The main outcome measurements included complete resection rate, complications, and long-term follow-up outcomes.RESULTS ER included endoscopic muscularis excavation in 179 cases, endoscopic full-thickness resection in 32 cases, and submucosal tunneling endoscopic resection in 18 cases. The median size of GISTs was 1.90 cm. Of the 229 GISTs, 147 were very low risk, 72 were low risk, 8 were intermediate risk, and 2 were high risk. Shortterm outcomes showed the complete resection rate was 96.5%, and 8 patients(3.5%) had complications. Of the 8 patients with complications, only one patient required surgical intervention. Long-term outcomes showed 225 patients were actively followed-up until composition of this manuscript. The remaining 4 patients were lost because of unrelated death. During the follow-up period(median, 57 mo), no residual, recurrent lesions, or distant metastasis were detected in any patients. Binary logistic regression analysis showed tumor size was a risk factor associated with a high mitotic index(≥ 5/50 HPF) of GISTs(P = 0.002).CONCLUSION ER seems to be an effective and safe method for gastric MP-GISTs ≤ 4.0 cm, and, for some intermediate or high risk GISTs, adjuvant therapy and/or additional surgery might be required to reduce the risk of recurrence or metastasis.展开更多

Eligible subjects(n = 6,613) were randomly divided into a training set(n1 =4,609) and a validation set(n2 = 2,004) at a ratio of 7:3. The training set was used to identify predictors of NAFLD risk using logistic regression analysis. An ANN was established to predict the NAFLD risk using a training set. Receiver operating characteristic(ROC) curve analysis was performed to evaluate the accuracy of the model using the training and validation sets.Results Our study found that the odds ratios(ORs) and 95% confidence intervals(CIs) of NAFLD for the highest quartile of plant-derived dietary retinol intake(i.e., provitamin A carotenoids, such as β-carotene)(OR = 0.75, 95% CI: 0.57 to 0.99) were inversely associated with NAFLD risk, compared to the lowest quartile of intake, after adjusting for potential confounders. The areas under the ROC curves were 0.874 and 0.883 for the training and validation sets, respectively. NAFLD occurs when its incidence probability is greater than 0.388.Conclusion The ANN model combined with plant-derived dietary retinol intake showed a significant effect on NAFLD. This could be applied to predict NAFLD risk in the American adult population when government departments formulate future health plans.展开更多

The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.展开更多

Methods： Single-factor analysis and multiple linear stepwise regression method were used to investigate 3933 cases between 2014 and 2016 in Beijing Hospital （China） whose main diagnosis was defined as unstable angina pectoris to determine the main factors influencing the inpatient medical expenditure,and decision tree method was adopted to establish the model of DRGs grouping combinations. Results： The major influential factors of inpatient medical expenditure included age, operative method, therapeutic effects as well as comorbidity and complications （CCs） of the disease, and the 3933 cases were divided into ten DRGs by four factors： age, CCs, therapeutic effects, and the type of surgery with corresponding inpatient medical expenditure standards setup. Data of nonparametric test on medical costs among different groups were all significant （P 〈 0.001, by Kruskal-Wallis test）, with R2 = 0.53 and coefficient of variation （CV） 0.524. Conclusions： The classification of DRGs by adopting the type of surgery as the main branch node to develop cost control standards in inpatient treatment of unstable angina pectoris is conducive in standardizing the diagnosis and treatment behaviors of the hospital and reducing economic burdens among patients.展开更多

It is also an effective approach in upgrading medical service and core competitiveness among medical institutions. This study aimed to build a quantitative medical technology evaluation system through questionnaire survey within medical institutions to perforna an assessment to medical technologies more objectively and accurately, and promote the management of medical quality technologies and ensure the medical safety of various operations among the hospitals. Methods： A two-leveled quantitative medical technology evaluation system was built through a two-round questionnaire survey of chosen experts. The Delphi method was applied in identifying the structure of evaluation system and indicators. The judgment of the experts on the indicators was adopted in building the matrix so that the weight coefficient and maximum eigenvalue （λ. max）, consistency index （CI）, and random consistency ratio （CR） could be obtained and collected. The results were verified through consistency tests, and the index weight coefficient of each indicator was conducted and calculated through analytical hierarchy process. Results： Twenty-six experts of different medical fields were involved in the questionnaire survey, 25 of whom successfully responded to the two-round research. Altogether, 4 primary indicators （safety, effectiveness, innovativeness, and benefits）, as well as 13 secondary indicators, were included in the evaluation system. The matrix is built to conduct the λ max, CI, and CR of each expert in the survey, and the index weight coefficients of primary indicators were 0.33, 0.28, 0.27, and 0.12, respectively, and the index weight coefficients of secondary indicators were conducted and calculated accordingly. Conclusions： As the two-round questionnaire survey of experts and statistical analysis were performed and credibility of the results was verified through consistency evaluation test, the study established a quantitative medical technology evaluation system model and assessment indicators within medical institutions based on the Delphi method and analytical hierarchy process. Moreover, further verifications, adjustments, and optimizations of the system and indicators will be performed in follow-up studies.展开更多

This study aimed to investigate the medical economic characteristics of cervical cancer patients with different payment modes within a Grade A tertiary hospital to provide evidence and suggestions for inpatient cost control and to verily the application of Gamma model in medical cost analysis. Methods： The basic and cost information of cervical cancer cases within a Grade A tertiary hospital in the year 2011-2016 were collected. The Gamma model was adopted to analyze the differences in each cost item between medical insured patient and uninsured patients. Meanwhile, the marginal means of different cost items were calculated to estimate the influence of payment modes toward different medical cost items among cervical cancer patients in the study. Results： A total of 1321 inpatients with cervical cancer between the 2011 and 2016 were collected through the medical records system. Of the 1321 cases~ 65.9% accounted for medical insured patients and 34.1% were uninsured patients. The total inpatient medical expenditure of insured patients was RMB 29,509.1 Yuan and uninsured patients was RMB 22,114.3 Yuan, respectively. Payment modes, therapeutic options as well as the recurrence and metastasis of tumor toward the inpatient medical expenditures between the two groups were statistically significant. To the specifics, drug costs accounted for 37.7% and 33.8% of the total, surgery costs accounted for 21.5% and 25.5%, treatment costs accounted for 18.7% and 16.4%, whereas the costs of imaging and laboratory examinations accounted for 16.4% and 15.2% for the insured patient and uninsured patients, respectively. As the effects of covariates were controlled, the total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory exainination costs showed statistical significance. The total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs of insured patient were 1.33, 1.42, 1.52, and 1.44 times of uninsured patients. Conclusions： The analysis of different payment modes toward the medical economic characteristics based on Gamma model is basically rational. Medical payment modes are having certain influence toward the hospitalization expenses of cervical cancer patients in an extent, as drug costs, treatment costs, and examination costs appear to be the main causes.展开更多

文摘Idiopathic pulmonary fibrosis(IPF)has a poor prognosis if left untreated;therefore,early treatment with pirfenidone is crucial.Lei et al conducted a retrospective analysis to evaluate the effectiveness of early pirfenidone treatment on lung function in 113 patients with IPF.In addition to other research,pirfeni-done has demonstrated efficacy in patients at all stages of IPF once correct diagnosis has been made.In advanced IPF,we include the requirement for pirfenidone.Therefore,it is essential to choose an appropriate method of adminis-tration method,such as inhalation.This may circumvent the drawbacks of the high cost and possible adverse effects of this drug.
文摘BACKGROUND In 2018,the diagnosis-related groups prospective payment system(DRGs-PPS)was introduced in a trial operation in Beijing according to the requirements of medical and health reform.The implementation of the system requires that more than 300 disease types pay through the DRGs-PPS for medical insurance.Colorectal cancer(CRC),as a common malignant tumor with high prevalence in recent years,was among the 300 disease types.AIM To investigate the composition and factors related to inpatient medical expenditure in CRC patients based on disease DRGs,and to provide a basis for the rational economic control of hospitalization expenses for the diagnosis and treatment of CRC.METHODS The basic material and cost data for 1026 CRC inpatients in a Grade-A tertiary hospital in Beijing during 2014-2018 were collected using the medical record system.A variance analysis of the composition of medical expenditure was carried out,and a multivariate linear regression model was used to select influencing factors with the greatest statistical significance.A decision tree model based on the exhaustiveχ^2 automatic interaction detector(E-CHAID)algorithm for DRG grouping was built by setting chosen factors as separation nodes,and the payment standard of each diagnostic group and upper limit cost were calculated.The correctness and rationality of the data were re-evaluated and verified by clinical practice.RESULTS The average hospital stay of the 1026 CRC patients investigated was 18.5 d,and the average hospitalization cost was 57872.4 RMB yuan.Factors including age,gender,length of hospital stay,diagnosis and treatment,as well as clinical operations had significant influence on inpatient expenditure(P<0.05).By adopting age,diagnosis,treatment,and surgery as the grouping nodes,a decision tree model based on the E-CHAID algorithm was established,and the CRC patients were divided into 12 DRG cost groups.Among these 12 groups,the number of patients aged≤67 years,and underwent surgery and chemotherapy or radiotherapy was largest;while patients aged>67 years,and underwent surgery and chemotherapy or radiotherapy had the highest medical cost.In addition,the standard cost and upper limit cost in the 12 groups were calculated and re-evaluated.CONCLUSION It is important to strengthen the control over the use of drugs and management of the hospitalization process,surgery,diagnosis and treatment to reduce the economic burden on patients.Tailored adjustments to medical payment standards should be made according to the characteristics and treatment of disease types to improve the comprehensiveness and practicability of the DRGs-PPS.

文摘Among refractive errors,astigmatism is the most common optical aberration,where refraction changes in different meridians of the eye.It causes blurred vision at any distance and includes corneal,lenticular,and retinal astigmatism.Cataract surgery used to cause a progressive increase in the pre-exisiting corneal astigmatism because of creating a surgically induced astigmatism,for example,a large size surgery incision.The development of surgical techniques during last decades has made cataract surgery interchange to treat preoperative corneal astigmatism at time of surgery.Nowadays,three surgical approaches can be used.By placing a sutureless clear corneal incision on the steep meridian of the cornea,a preoperative corneal astigmatism less than 1.0 D can be corrected.Single or paired peripheral corneal relaxing incisions(PCRIs)provide 1.0-3.0 D corneal astigmatism correction.PCRIs are typically used for treating 1.0-1.5 D of regular corneal astigmatism,if more than 2.0 D,the risk of overcorrection and irregular astigmatism is increased.When toric intraocular lenses(IOLs)are unavailable in markets,PCRIs are still a reasonable option for patients with up to 3.0 D of pre-existing corneal astigmatism.Toric IOLs implantation can correct 1.0-4.5 D of corneal astigmatism.Several IOLs are approved to correct a high degree of corneal astigmatism with cylinder power up to 12.0 D.These approaches can be used alone or in combination.
文摘Objective:To describe the situation of measles in Sri Lanka from May to November,2023 and to define the role of virology laboratory towards case confirmation and epidemiological and genetic characterization of the outbreak.Methods:This retrospective study analyzed all samples tested for measles from 1st of May to 30th of November,2023 at National Measles Rubella Laboratory,Sri Lanka.According to the World Health Organization(WHO)algorithm,serum and oropharyngeal/nasopharyngeal swabs were tested with WHO recommended kits for anti-measles IgM and measles virus specific RNA,respectively.Selected RNA positive samples were sequenced at reference laboratory,India.Analysis of sequencing data and construction of phylogenetic tree were carried out at National Measles Rubella Laboratory.Data was analyzed using descriptive statistics.Results:Of the total 1132 serum samples and 497 oropharyngeal/nasopharyngeal swabs from 1326 patients,657(49.5%)patients were confirmed as measles by anti-measles IgM,measles virus specific RNA or both.Males(55.6%,n=365)and the age group from>20 to≤30 years(33.0%,n=217)predominated positive patients.All provinces reported measles positive cases.All samples sequenced(100%,n=42)were genotype D8 with 95.2%(n=40)bearing Victoria.Australia origin.Conclusions:We described resurgence of measles in an eliminated country,confirming the genotype to be D8,one of the two genotypes currently circulating globally.Further,the study strongly convinced the importance of a strengthened virological surveillance system in an eliminated country,despite its eliminated status.
文摘BACKGROUND Complement components could contribute to the tumor microenvironment and the systemic immune response.Nevertheless,their role in colorectal cancer(CRC)remains a contentious subject.AIM To elucidate the relationship between complement components and CRC risk and clinical characteristics.METHODS Searches were conducted in PubMed,the Cochrane Library,and the China National Knowledge Infrastructure database until June 1,2023.We included cohort studies encompassing participants aged≥18 years,investigating the association between complement components and CRC.The studies were of moderate quality or above,as determined by the Agency for Healthcare Research and Quality.The meta-analysis employed fixed-effects or random-effects models based on the I^(2)test,utilizing risk ratio(RR)and their corresponding 95%confidence interval(CI)for outcomes.Sensitivity and subgroup analyses were performed to validate the robustness of the collective estimates and identify the source of heterogeneity.RESULTS Data from 15 studies,comprising 1631 participants that met the inclusion criteria,were included in the meta-analysis.Our findings indicated that protein levels of cluster of differentiation 46(CD46)(RR=3.66,95%CI:1.75-7.64,P<0.001),CD59(RR=2.86,95%CI:1.36-6.01,P=0.005),and component 1(C1)(RR=5.88,95%CI:1.75-19.73,P=0.004)and serum levels of C3(standardized mean difference=1.82,95%CI:0.06-3.58,P=0.040)were significantly elevated in patients with CRC compared to healthy controls.Strong expression of CD55 or CD59 was associated with a higher incidence of lymph node metastasis,whereas strong CD46 expression correlated with a higher incidence of tumor differentiation compared to low CD46 expression(P<0.05 for all).Although specific pooled results demonstrated notable heterogeneity,subgroup analyses pointed to regional differences as the primary source of inconsistency among the studies.CONCLUSION Our analysis underscores that increased levels of specific complement components are associated with a heightened risk of CRC,emphasizing the potential significance of monitoring elevated complement component levels.

文摘AIM To evaluate the long-term efficacy of endoscopic resection(ER) for small(≤ 4.0 cm) gastric gastrointestinal stromal tumors(GISTs) originating from the muscularis propria layer.METHODS Between June 2005 and February 2015, we retrospectively analyzed 229 consecutive patients with gastric MP-GISTs who underwent ER with a follow-up at least 36 mo. The main outcome measurements included complete resection rate, complications, and long-term follow-up outcomes.RESULTS ER included endoscopic muscularis excavation in 179 cases, endoscopic full-thickness resection in 32 cases, and submucosal tunneling endoscopic resection in 18 cases. The median size of GISTs was 1.90 cm. Of the 229 GISTs, 147 were very low risk, 72 were low risk, 8 were intermediate risk, and 2 were high risk. Shortterm outcomes showed the complete resection rate was 96.5%, and 8 patients(3.5%) had complications. Of the 8 patients with complications, only one patient required surgical intervention. Long-term outcomes showed 225 patients were actively followed-up until composition of this manuscript. The remaining 4 patients were lost because of unrelated death. During the follow-up period(median, 57 mo), no residual, recurrent lesions, or distant metastasis were detected in any patients. Binary logistic regression analysis showed tumor size was a risk factor associated with a high mitotic index(≥ 5/50 HPF) of GISTs(P = 0.002).CONCLUSION ER seems to be an effective and safe method for gastric MP-GISTs ≤ 4.0 cm, and, for some intermediate or high risk GISTs, adjuvant therapy and/or additional surgery might be required to reduce the risk of recurrence or metastasis.
文摘Evaluating patients with chronic venous leg ulcers(CVLUs)is essential to find the underlying etiology.The basic tenets in managing CVLUs are to remove the etiological causes,to address systemic and metabolic conditions,to examine the ulcers and artery pulses,and to control wound infection with debridement and eliminating excessive pressure on the wound.The first-line treatments of CVLUs remain wound care,debridement,bed rest with leg elevation,and compression.Evidence to support the efficacy of silver-based dressings in healing CVLUs is unavailable.Hydrogen peroxide is harmful to the growth of granulation tissue in the wound.Surgery options include a high ligation with or without stripping or ablation of the GSVs depending on venous reflux or insufficiency.Yet,not all CVLUs are candidates for surgical treatment because of comorbidities.When standard care of wound for 4 wk failed to heal CVLUs effectively,use of advanced wound care should be considered based on the available evidence.Negative pressure wound therapy facilitates granulation tissue development,thereby helping closure of CVLUs.Autologous split-thickness skin grafting is still the gold standard approach to close huge CVLUs.Hair punch graft appears to have a better result than traditional hairless punch graft for CVLUs.Application of adipose tissue or placenta-derived mesenchymal stem cells is a promising therapy for wound healing.Autologous platelet-rich plasma provides an alternative strategy for surgery for safe and natural healing of the ulcer.The confirmative efficacy of current advanced ulcer therapies needs more robust evidence.
文摘Objective:Aging caused by a deficiency syndrome can be found in ancient and modern traditional Chinese medicine literature.Qi deficiency syndrome(QDS)is a vital factor in the aging process.This study aimed to establish a full-scale trial to evaluate the prevalence,symptom severity,frequency,and distribution of QDS in different age groups and varying health status to elucidate the role of qi deficiency in the aging process and deterioration of health.Methods:This cross-sectional study was conducted in four hospitals in China,and data from 1220 participants were included.The participants,aged between 20 and 79 years,completed questionnaires that recorded prevalence of QDS and severity or frequency of relevant symptoms,then were interviewed by investigators.We used frequency analysis and chi-squared tests to perform comparative analysis of prevalence in different age and health groups;we used a ranksum tests for quantitative analysis of symptoms severity and frequency scores;we performed a regression analysis of correlation between syndrome occurrence and potential factors using nonconditional binary logistic stepwise regression of numerical variables.P<0.05 was considered statistically significant.Results:Prevalence,symptom severity and frequency scores of QDS showed a rising trend when physical condition worsened,rather than when age increased.Health status,fatigue,shortness of breath or no desire to talk,spontaneous sweating,swollen tongue with teeth marks on side,and deficient and weak pulse,rather than increasing age were contributing factors to this syndrome.Distribution of QDS in certain health and age stages showed remarkable irregularities.Conclusions:Qi deficiency may be a contributing factor for sub-health(sub-optimal health)and chronic diseases rather than aging.It may play a crucial role in chronic disease pathogenesis of young and middle-aged people,and in sub-health pathogenesis of older adults.Recognition of the warning signs and symptoms of QDS may lead to early intervention and prevention of subhealth,and chronic diseases.

文摘Objective This study aimed to develop an artificial neural network(ANN) model combined with dietary retinol intake from different sources to predict the risk of non-alcoholic fatty liver disease(NAFLD) in American adults.Methods Data from the 2007 to 2014 National Health and Nutrition Examination Survey(NHANES)2007–2014 were analyzed. Eligible subjects(n = 6,613) were randomly divided into a training set(n1 =4,609) and a validation set(n2 = 2,004) at a ratio of 7:3. The training set was used to identify predictors of NAFLD risk using logistic regression analysis. An ANN was established to predict the NAFLD risk using a training set. Receiver operating characteristic(ROC) curve analysis was performed to evaluate the accuracy of the model using the training and validation sets.Results Our study found that the odds ratios(ORs) and 95% confidence intervals(CIs) of NAFLD for the highest quartile of plant-derived dietary retinol intake(i.e., provitamin A carotenoids, such as β-carotene)(OR = 0.75, 95% CI: 0.57 to 0.99) were inversely associated with NAFLD risk, compared to the lowest quartile of intake, after adjusting for potential confounders. The areas under the ROC curves were 0.874 and 0.883 for the training and validation sets, respectively. NAFLD occurs when its incidence probability is greater than 0.388.Conclusion The ANN model combined with plant-derived dietary retinol intake showed a significant effect on NAFLD. This could be applied to predict NAFLD risk in the American adult population when government departments formulate future health plans.

文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
文摘BACKGROUND Percutaneous kyphoplasty(PKP)is a pivotal intervention for osteoporotic fractures,pathological vertebral compression fractures,and vertebral bone tumors.Despite its efficacy,the procedure presents challenges,notably complications arising from intradural cement leakage.Timely and accurate diagnosis,coupled with emergent intervention is imperative to improve patient prognosis.This case report illuminates the intricacies and potential complications associated with PKP,emphasizing the critical need for vigilant monitoring,prompt diagnosis,and immediate intervention to mitigate adverse outcomes.CASE SUMMARY A 58-year-old male patient,experiencing a T7 osteoporosis-related pathological compression fracture,underwent PKP at a local hospital.Two weeks postprocedure,the patient developed paraplegic and dysuric symptoms,necessitating emergency decompression surgery.Gradual improvement was achieved,marked by the restoration of muscle strength,sensation,and mobility.CONCLUSION PKP Intradural cement leakage following PKP is unusual and potentially fatal.Prompt imaging examinations,urgent evaluation,and the decompression surgery are essential,which help alleviate symptoms associated with spinal damage,markedly improving the overall prognosis.
文摘Nonalcoholic fatty liver disease(NAFLD)is the most prevalent type of chronic liver disease.However,the disease is underappreciated as a remarkable chronic disorder as there are rare managing strategies.Several studies have focused on determining NAFLD-caused hepatocyte death to elucidate the disease pathoe-tiology and suggest functional therapeutic and diagnostic options.Pyroptosis,ferroptosis,and necroptosis are the main subtypes of non-apoptotic regulated cell deaths(RCDs),each of which represents particular characteristics.Considering the complexity of the findings,the present study aimed to review these types of RCDs and their contribution to NAFLD progression,and subsequently discuss in detail the role of necroptosis in the pathoetiology,diagnosis,and treatment of the disease.The study revealed that necroptosis is involved in the occurrence of NAFLD and its progression towards steatohepatitis and cancer,hence it has potential in diagnostic and therapeutic approaches.Nevertheless,further studies are necessary.
文摘Gastrointestinal(GI)cancers,which predominantly manifest in the stomach,colorectum,liver,esophagus,and pancreas,accounting for approximately 35%of global cancer-related mortality.The advent of liquid biopsy has introduced a pivotal diagnostic modality for the early identification of premalignant GI lesions and incipient cancers.This non-invasive technique not only facilitates prompt therapeutic intervention,but also serves as a critical adjunct in prognosticating the likelihood of tumor recurrence.The wealth of circulating exosomes present in body fluids is often enriched with proteins,lipids,microRNAs,and other RNAs derived from tumor cells.These specific cargo components are reflective of processes involved in GI tumorigenesis,tumor progression,and response to treatment.As such,they represent a group of promising biomarkers for aiding in the diagnosis of GI cancer.In this review,we delivered an exhaustive overview of the composition of exosomes and the pathways for cargo sorting within these vesicles.We laid out some of the clinical evidence that supported the utilization of exosomes as diagnostic biomarkers for GI cancers and discussed their potential for clinical application.Furthermore,we addressed the challenges encountered when harnessing exosomes as diagnostic and predictive instruments in the realm of GI cancers.
文摘Background： With the rising incidence as well as the medical expenditure among patients with unstable angina pectoris, the research aimed to investigate the inpatient medical expenditure through the combination of diagnosis-related groups （DRGs） among patients with nnstable angina pectoris in a Grade A tertiary hospital to conduct the referential standards of medical costs for the diagnosis. Methods： Single-factor analysis and multiple linear stepwise regression method were used to investigate 3933 cases between 2014 and 2016 in Beijing Hospital （China） whose main diagnosis was defined as unstable angina pectoris to determine the main factors influencing the inpatient medical expenditure,and decision tree method was adopted to establish the model of DRGs grouping combinations. Results： The major influential factors of inpatient medical expenditure included age, operative method, therapeutic effects as well as comorbidity and complications （CCs） of the disease, and the 3933 cases were divided into ten DRGs by four factors： age, CCs, therapeutic effects, and the type of surgery with corresponding inpatient medical expenditure standards setup. Data of nonparametric test on medical costs among different groups were all significant （P 〈 0.001, by Kruskal-Wallis test）, with R2 = 0.53 and coefficient of variation （CV） 0.524. Conclusions： The classification of DRGs by adopting the type of surgery as the main branch node to develop cost control standards in inpatient treatment of unstable angina pectoris is conducive in standardizing the diagnosis and treatment behaviors of the hospital and reducing economic burdens among patients.
文摘Background： The development and application of medical technologies reflect the medical quality and clinical capacity of a hospital. It is also an effective approach in upgrading medical service and core competitiveness among medical institutions. This study aimed to build a quantitative medical technology evaluation system through questionnaire survey within medical institutions to perforna an assessment to medical technologies more objectively and accurately, and promote the management of medical quality technologies and ensure the medical safety of various operations among the hospitals. Methods： A two-leveled quantitative medical technology evaluation system was built through a two-round questionnaire survey of chosen experts. The Delphi method was applied in identifying the structure of evaluation system and indicators. The judgment of the experts on the indicators was adopted in building the matrix so that the weight coefficient and maximum eigenvalue （λ. max）, consistency index （CI）, and random consistency ratio （CR） could be obtained and collected. The results were verified through consistency tests, and the index weight coefficient of each indicator was conducted and calculated through analytical hierarchy process. Results： Twenty-six experts of different medical fields were involved in the questionnaire survey, 25 of whom successfully responded to the two-round research. Altogether, 4 primary indicators （safety, effectiveness, innovativeness, and benefits）, as well as 13 secondary indicators, were included in the evaluation system. The matrix is built to conduct the λ max, CI, and CR of each expert in the survey, and the index weight coefficients of primary indicators were 0.33, 0.28, 0.27, and 0.12, respectively, and the index weight coefficients of secondary indicators were conducted and calculated accordingly. Conclusions： As the two-round questionnaire survey of experts and statistical analysis were performed and credibility of the results was verified through consistency evaluation test, the study established a quantitative medical technology evaluation system model and assessment indicators within medical institutions based on the Delphi method and analytical hierarchy process. Moreover, further verifications, adjustments, and optimizations of the system and indicators will be performed in follow-up studies.
文摘Background： Cervical cancer shows a growing incidence and medical cost in recent years that has increased severe financial pressure on patients and medical insurance institutions. This study aimed to investigate the medical economic characteristics of cervical cancer patients with different payment modes within a Grade A tertiary hospital to provide evidence and suggestions for inpatient cost control and to verily the application of Gamma model in medical cost analysis. Methods： The basic and cost information of cervical cancer cases within a Grade A tertiary hospital in the year 2011-2016 were collected. The Gamma model was adopted to analyze the differences in each cost item between medical insured patient and uninsured patients. Meanwhile, the marginal means of different cost items were calculated to estimate the influence of payment modes toward different medical cost items among cervical cancer patients in the study. Results： A total of 1321 inpatients with cervical cancer between the 2011 and 2016 were collected through the medical records system. Of the 1321 cases~ 65.9% accounted for medical insured patients and 34.1% were uninsured patients. The total inpatient medical expenditure of insured patients was RMB 29,509.1 Yuan and uninsured patients was RMB 22,114.3 Yuan, respectively. Payment modes, therapeutic options as well as the recurrence and metastasis of tumor toward the inpatient medical expenditures between the two groups were statistically significant. To the specifics, drug costs accounted for 37.7% and 33.8% of the total, surgery costs accounted for 21.5% and 25.5%, treatment costs accounted for 18.7% and 16.4%, whereas the costs of imaging and laboratory examinations accounted for 16.4% and 15.2% for the insured patient and uninsured patients, respectively. As the effects of covariates were controlled, the total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory exainination costs showed statistical significance. The total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs of insured patient were 1.33, 1.42, 1.52, and 1.44 times of uninsured patients. Conclusions： The analysis of different payment modes toward the medical economic characteristics based on Gamma model is basically rational. Medical payment modes are having certain influence toward the hospitalization expenses of cervical cancer patients in an extent, as drug costs, treatment costs, and examination costs appear to be the main causes.
