Methods: RBL-2H3 cells were used to study the degranulation by co-culture with positive control C48/80 and some TCMIs through morphological and ultra-structure observation, β-hexosaminidase activity detection. RBL-2H3 cell degranulation test was established to detect β-hexosaminidase activity caused by 17 kinds of TCMIs and their ingredients. The cytotoxicity effect of some TCMIs on both RBL 2H3 and BRL cells was measured by CCK-8 assay. Results: Toluidine blue staining and ultra-structure of electronic microscope observation of treated RBL-2H3 cells showed degranulation morphologically. Detection of β-hexosaminidase activity in the supernatant of treated cells showed some TCMIs had elevated enzyme release rates. Further analysis of the ingredients and compound in Tanreqing Injection and Shengmai Injection showed Scutellaria baicalensis Georgi in Tanreqing Injection, Red ginseng and Fructus Schisandrae Chinensis in Shengmai Injection were responsible to the degranulation of RBL-2H3 cells. Osmotic pressures and pH influenced RBL-2H3 degranulation. High Osmotic pressure of Tanreqing Injection and low pH of chlorogenic acid at 2.5 and 5.0 mmol/L congcentration might be responsible to high β-hexosaminidase activity. Most of the TCMIs inducing degranulation had cytotoxicity effect for both RBL-2H3 and BRL cells, but some TCMIs inducing degranulation had no cytotoxicity effect. Conclusion: Some TCMIs can induce degranulation of RBL-2H3 cells;RBL-2H3 cell degranulation test can be used in non-clinical stage to detect the risk causing anaphylactoid reactions. Osmotic pressures and pH influenced RBL-2H3 degranulation, and they should be measured before testing. The mechanism of degranulation caused by some TCMIs is cytotoxic, and some are non-cytotoxic and may be through exicytosis.展开更多

METHODS The clinical features and follow-up data from 108 NHL patients whose diagnosis was confirmed through pathologic examination during a period from January 2000 to January 2008 were reviewed. SPSS 14.0 package was used for statistical analysis, and the Kaplan-Meier curve method for assessment of survival probability. Furthermore, the Cox regression model was utilized for multivariate analysis for all parameters which were statistically significant and confirmed by univariate analysis. RESULTS In the 108 NHL patients, the male-female ratio was approximately 1.5 ： 1 and the median age was 48 years. Before treatment, 61.1% of the patients had stage I and II disease, based on the Ann Arbor Clinical Classification. The ECOG performance status （PS） score reached a range from 0 to 1 in about 93% of total patients, and an elevated serum lactate dehydrogenase （LDH） was seen in 19.2%. Based on the international prognostic index （IPI） score, 80.6% of patients were in the low risk group. On admission, 35.2% of patients had an ALC 〈 1 × 10^9/L. Anemia, i.e. hemoglobin （Hb） 〈 110 g/L was seen in 29.6% and B-symptoms in 26.9% of patients. The mean value of Hb was 129.2 ＋ 17.5 g/L in patients with ALC 〉 1 x 109/L （n = 70） and 98.1 ＋ 20.6 g/L in those with ALC 〈 1 × 10^9/L （n = 38）, and the difference between the 2 groups was statistically significant （P 〈 0.05）. With a median follow-up period of 2 years, the median survival time was 2.3 years among all patients. The 2-year and 5-year overall survival （OS） rates were 73.2% and 39.6%, respectively. It was shown by univariate analysis that ALC 〈 1 × 10^9/L, Hb ≤ 110 g/L, B-symptoms, and the IPI 〉 2 were statistically significant unfavorable prognostic factors in NHL patients. Multivariate analysis revealed that ALC 〈 1 × 10^9/L, B-symptoms, and the IPI 〉 2 were independent unfavorable prognostic factors in NHL patients. CONCLUSION The numerical value of ALC and the presence＂ of B-symptoms are prognostic factors independent of IPI in NHL patients. Clinically, determining prognosis based on the IPI combined with simple clinical parameters, such as the numerical value of ALC and B-symptom status, might be of more practical value in determining individualized treatment regimens for NHL patients.展开更多
