Journal of Chongqing Medical University 1986;0(04):-
Objective:To make use of the characteristics of presenting and processing tumor antigen of dendritic cell to enhance generation of isotypical but xenogenous T lymphocyte.Methods:Autologous dendritic cells were obtained by culturing peripheral blood monocyte of patients with cervical cancer in the presence of granulocyte-macrophage colony stimulating factor(GM-CSF) and interleukin-4(IL-4).Dendritic cells were loaded with tumor cell lysate and co-cultured with heterogenous PBMCs from patients to induce generation of tumor specific cytotoxic T cell.The generation rate was measured by MTT.Results:Tumor lysate-loaded DC which was isolated from peripheral blood monocyte of patients with cervical cancer could induce the generation of isotypical but xenogenous T lymphcyte.There was no significant difference between tumor tissue lysate and tumor cell strain lysate(P

5.Infection status and viral replication level are not significantly correlated with serum levels of leptin and adiponectin in patients with chronic HBV infection
Journal of Clinical Hepatology 2014;30(10):1035-1038
Objective To investigate the changes in serum leptin and adiponectin levels and their significance in patients with chronic hepa-titis B virus (HBV)infection.Methods One hundred and twenty -five patients with chronic HBV infection (44 HBeAg -positive cases, 31 HBeAg -negative cases of chronic hepatitis B,23 chronic HBV carriers,and 27 inactive HBsAg carriers)were recruited in the present study.Fifty -five healthy people served as the control group.Blood samples were collected at 8 to 9 AMof the next morning after overnight fasting.Blood glucose,blood lipids,renal and liver function parameters,fasting insulin,serum HBV markers,and HBV DNA concentration were determined,and HOMA -IR was calculated.Serum levels of leptin and adiponectin were measured by ELISA.Continuous data were expressed as mean ±SD,and Student′s t -test,analysis of variance,linear regression analysis,and multiple regression analysis were ap-plied in the analysis of all experimental data.Results There were no significant differences in serum levels of leptin and adiponectin be-tween patients with chronic HBV infection and the control group (P =0.480;P =0.321),even after stratification by gender (males:P =0.210 /0.895;females:P =0.404 /0.066).After patients with chronic HBV infection were divided into subgroups by HBeAg status,HBV DNA,or ALT level,there were no significant differences in serum levels of leptin and adiponectin between groups (leptin:P =0.820 /0.296 /0.212;adiponectin:P =0.268 /0.760 /0.224).Conclusion For patients with chronic HBV infection,infection status and viral replication level are not significantly correlated with serum levels of leptin and adiponectin.

The Journal of Practical Medicine 2016;32(18):3023-3026
Objective To explore the clinical value of tuberculous infection of T cells spot test (T-SPOT. TB)for diagnosing tuberculous pleurisy in immunocompromised patients. Methods The sensitivities of T-SPOT. TB,ADA, TB-DNA and tuberculosis antibodies to tuberculous pleurisy in 54 immunocompromised patients were compared.Among these patients,22 were retested by T-SPOT. TB after 2 months anti-tuberculosis treatment. Spot forming cells(SFCs) were compared before and after treatment. Results The diagnostic sensitivity of T-SPOT.TB (79.63%)was significantly higher than those of ADA (64.81%),TB-DNA (48.15%)and tuberculosis antibodies (55.56%) (P<0.05).22 patients were retested by the T-SPOT.TB after anti-TB treatment (2 months), the results showed that the positive rate of T-SPOT.TB was 90.91%,not significantly than previous tests (P<0.05).Both ESAT-6 and CFP-10 specific SFCs decreased significantly compared with those before anti-TB treatment (t=2.728 and 2.400,P<0.05 respectively). Conclusions T-SPOT.TB assay has satisfactory sensitivity and could be used in diagnosis of tuberculous pleurisy in immunocompromised patients.
7.DYNAMIC ANALYSIS OF RHODAMINE 123 STAINING OF HUMAN BRONCHIAL EPITHELIUM DURING THE WOUND REPAIR PROCESS INDUCED BY FLUOROURACIL
Acta Anatomica Sinica 2002;0(06):-
Objective To analyze the condition of Rhodamine 123 staining of human bronchial epithelium in vitro during the wound-repair process induced by fluorouracil(5-FU). Methods The bronchial epithelial cells in normal and 5-FU injurious group were obtained by enzymatic digestion and analyzed by flow cytometry.1.PI staining to identify the percentage of cells in different cell phase;2.Rhodamine 123 staining in live cells was to contrast the percentage of negative cells in two groups. Results 1.Analysis of cell cycle:apoptotic cells in injurious group increased,cells in S+G-2/M phase almost disappeared,majority of the remain live cells of injurious group were in G-0/G-1 phase;with the recover of bronchial epithelium,cells in S+G-2/M phase increased;2.The percentage of Rhodamine 123 negative staining live cells in injurious group was higher than that of normal group,and with the recover of bronchial epithelium,this percentage lowered to nearly normal.Conclusion 5-FU can make the cycling cells apoptosis and reserve quiescent phase cells.Among them there were bronchial stem cells which had the capacity to efflux Rhodamine 123.Just the proliferation and differentiation of these stem cells regenerated bronchial epithelium.Rhodamine 123 staining to sort the remain cells after 5-FU treatment by FACS can be used to enrich and purify bronchial stem cells.

Clinical Medicine of China 1999;0(02):-
Objective To observe the application value of cardiac troponin I (cTnI),cardiac troponin T (cTnT) and creatine kinase MB (CK MB) for the early diagnosis of acute myocardial infarction (AMI).Methods The same serum sample was measured to detect the indexes of cTnI,cTnT and CK MB levels in 60 patients with AMI and 40 patients with UA.Comparison between AMI and UA was performed and all the indexes were analysed contrastively.Results The sensitivity of cTnI and cTnT was higher than that of CK MB,and their positive rates were 63.3%,46.7% and 18.3% respectively (P0.05) and the specificity of the three indexes were almost the same without significant difference.Conclusion cTnI and cTnT,as specific markers of cardiac damage,are more sensitive and specific in the early diagnosis of AMI.As a convenient,swift and accurate measurement method,cTnI has significant clinical value.
