METHODS The study was approved by the ethics committee of the Second Affiliated Hospital Zhejiang University School of Medicine(SAHZU). From April 2004 to July 2014, 20 patients were enrolled who underwent anatomic isolated caudate lobectomy at SAHZU. Clinical and postoperative pathological data were analyzed. RESULTS Of the total 20 cases, 4 received isolated complete caudate lobectomy(20%) and 16 received isolated partial caudate lobectomy(80%). There were 4 caseswith the left approach(4/20, 20%), 6 cases with the right approach(6/20, 30%), 7 cases with the bilateral combined approach(7/20, 35%), 3 cases with the anterior approach(3/20, 15%), and the hanging maneuver was also combined in 2 cases. The median tumor size was 5.5 cm(2-12 cm). The median intraoperative blood loss was 600 m L(200-5700 m L). The median intra-operative blood transfusion volume was 250 m L(0-2400 m L). The median operation time was 255 min(110-510 min). The median post-operative hospital stay was 14 d(7-30 d). The 1-and 3-year survival rates for malignant tumor were 88.9% and 49.4%, respectively. CONCLUSION Caudate lobectomy was a challenging procedure. It was demonstrated that anatomic isolated caudate lobectomy can be done safely and effectively.展开更多

So far, only 22 cases have been reported since 1999. All the cases, except one, exhibited benign features. Here, we report the first case of malignant pancreatic SFT with typical Doege-Potter syndrome, along with the clinical and pathologic evidence of its systemic metastasis.CASE SUMMARY The patient was a 48-year-old man with a 1-year history of pancreatic and liver masses and refractory hypoglycemia. Increased uptake of the tracer fluorodeoxyglucose(FDG) was found in the liver and bones by fluorine-18 FDG positron emission tomography/computed tomography. After multidisciplinary discussion, a distal pancreatectomy procedure was performed, and histological examination showed a lesion composed of abundant heterogeneous spindle cells with localized necrosis. On immunohistochemistry evaluation, STAT6 was found to be diffusely expressed in the tumor. Based on the overall evidence, the patient was diagnosed with malignant pancreatic SFT with liver and bone metastases.CONCLUSION The diagnosis of malignant SFT requires comprehensive evidence including clinical, immunohistochemistry, and histological features. This case may be presented as a reference for diagnoses and management of malignant pancreatic SFTs with systemic metastasis.展开更多

V. dahliae is especially difficult to control because it persists in soil as resting structures, called microsclerotia, for several years in the absence of a host plant. The dormant microsclerotia are the primary infectious propagules and germinate when they are stimulated by root exudates. Infection of cotton roots by V. dahliae in soi~ naturally leads to the colonization of vascular tissues, from the parasitic to saprophytic phase, when mycelia and melanized dormancy microsclerotia are produced in the infected cotton, resulting in vessel blockage and cotton wilt disease (Gerik and Huisman, 1988).展开更多

The colonization of cotton roots by V. dahliae in soil naturally leads to the colonization of vascular tissues in cotton (Garber and Houston, 1966; Gerik and Huisman, 1988). Recently, the development of confocal laser scanning microscopy (CLSM) has significantly increased our knowledge of the colonization process of V. dahliae on various plant roots (Eynck et al., 2007; Vallad and Subbarao, 2008; Prieto et al., 2009; Zhang et al., 2012). However, the comprehensive observation of the cotton living root colonization process by V. dahliae under CLSM is not likely to be practicable due to the large size of cotton roots.展开更多

文摘Aim:The transjugular intrahepatic portosystemic shunt(TIPS)procedure has been performed in China for 30 years,but our understanding of the status and difficulties associated with the use of TIPS for portal hypertension is incomplete.This study aims to investigate the current situation of the use of TIPS for portal hypertension,which should aid the development of TIPS in China.Methods:This study involved a questionnaire survey,initiated by the China Portal Hypertension Alliance(CHESS)to investigate the use of TIPS for portal hypertension in China.Questionnaires were released on the Internet between August 16,2022 and September 16,2022.Detailed information was collected from 545 hospitals contracted by the CHESS in China,which performed TIPS surgery in 2021.Results:The 545 hospitals covers the majority of hospitals in China that conduct TIPS intervention.In the survey,a total of 13,527 TIPS interventions were carried out with 94.1%(498/545)of them had a system of routine follow‐up after TIPS.The majority(42.6%[232/545])believed that the main indication of TIPS was the control of acute bleeding.Overall,48.1%(262/545)carried out early or pre‐emptive TIPS,53.0%(289/545)carried out TIPS for cavernous transformation of the portal vein,and 81.0%(441/545)chose routine embolization of collateral circulation during operation.Most used coils(97.0%[475/490])and biological glue(72.0%[353/490])as embolic materials,and 78.5%(428/545)routinely performed intraoperative portal pressure gradient measurements.When selecting TIPS stents,57.1%(311/545)chose viator‐specific stents,and 57.2%(312/545)chose conventional anticoagulation after TIPS.Conventional anticoagulation after TIPS is over a time interval of 3–6 months(55.4%[173/312]).The limitation of TIPS surgery is mainly its cost(72.3%[394/545])and insufficient understanding of the procedure by doctors in other related departments(77.4%[422/545]).Most of the hospital teams accept the use of domestic instruments in TIPS surgery(92.7%[505/545]).Conclusions:This survey shows that TIPS is an essential part of the treatment of portal hypertension in China.TIPS is widely used in Chinese patients with portal hypertension,and this survey presents a more comprehensive picture of the options and difficulties encountered in the implementation of TIPS.In the future,it is necessary to promote TIPS technology and further standardize surgical indications,routine operations,and instrument application.
