Objective To investigate the relationship between accompanying infection and the change of immunologic function in type 2 diabetes mellitus ( T2DM) patients.Methods One hundred and fifteen T2DM patients with infection and 95 T2DM patients with no infection were selected,and 102 subjects with no history of dia-betes were selected as no diabetetes with infection group.The venous blood of all groups were sampled after an over-night fast of 12h.Glycosylated hemoglobin a1c(HbA1c) level was tested by glycosylated hemoglobin automatic analy-zer.The levels of T cell subsets including CD3 ,CD4 ,CD8 ,NK cell and B cell ratio were tested by flow cytometry,Ig and complement level was tested by immune nephelometry.Results The level of body mass indices(BMI) in T2DM patients with infection group[(27.39 ±9.18) kg/m2 ] and with no infection group[(26.15 ±7.39) kg/m2 ] were higher than no diabetes with infection group (24.21 ±5.37)kg/m2 (t =2.548,4.702,all P <0.05).The levels of IgG,IgA,IgM,C3 ,C4 in T2DM with infection group were (11.83 ±3.92)mg/mL,(3.02 ±0.96)mg/mL,(3.38 ± 0.82)mg/mL,(1.70 ±0.38)mg/mL,(0.52 ±0.18)mg/mL,which in T2DM with non infection group were (12.46 ± 2.47)mg/mL,(2.63 ±1.37)mg/mL,(2.91 ±1.79)mg/mL,(1.58 ±0.43)mg/mL,(0.46 ±0.31)mg/mL,which in no diabetetes with infection group were (13.26 ±3.74)mg/mL,(2.06 ±1.86)mg/mL,(2.49 ±1.01)mg/mL, (1.19 ±0.82)mg/mL,(0.30 ±0.05)mg/mL.In T2DM with non infection group and T2DM with infection group, humoral immunity index including the level of IgG was lower and IgA,IgM,C3 ,C4 levels were higher than no dia-betetes with infection group,the differences were statistically significant(t =7.052,23.059,12.617,18.326,8.730, all P <0.05).The levels of CD4 ,CD8 ,NK,CD4 /CD8 ,CD3 were (37.68 ±8.39)%,(31.58 ±6.98)%,(10.76 ± 6.49)%,(1.19 ±0.75),(62.83 ±5.28)% in T2DM with infection group,which in T2DM with non infection group were (39.23 ±10.28)%,(27.61 ±5.65)%,(14.89 ±7.12)%,(1.39 ±1.01),(64.19 ±6.46)%,which in no diabetes with infection group were (42.91 ±5.67)%,(25.17 ±7.25)%,(16.39 ±6.24)%,(1.86 ±0.82), (73.65 ±9.10)%.Cellular immunity index containing CD4 ,CD8 ,NK,CD4 /CD8 ,CD3 levels decreased more signifi-cantly than no diabetic group,T2DMI group compared with T2DM group,the levels of IgG,CD4 ,CD8 ,NK,B cell ratio, CD4 /CD8 ,CD3 decreased obviously,while the levels of IgA,IgM,C3 declined greatly,there were significant differences (t =11.038,8.237,18.549,25.871,2.436,all P <0.05).Conclusion Patients with T2DM have humoral and cellular immunity abnormalities,T2DM patients with infection is closely related with the imbalance of immunologic function.

Objective To study the effect and mechanism of strengthening the spleen and tonifying the kidney on the function and apoptosis of kidney in rats.Methods The 42 male SD rats were randomly divided into quiet control group,exhausted exercise group and strengthening the spleen and tonifying the kidney group.Twenty four hours after exhaustive exercise,the concentrations of blood urea nitrogen(BUN),serum creatinine and urinary protein were determined.The apoptosis in kidneys of rats was detected by TUNEL.The structure of kidney was observed in the HE stain.Results Comparing with the exhausted exercise group,the concen- trations of BUN,serum creatinine and apoptotic index were lower significantly(P

Objective To study the effects of p27kip1 gene on the apoptosis in esophageal carcinoma cell lines EC 9706. Methods A replication deficient adenovirus vector encoding p27kip1(ad p27kip1) was constructed and human esophageal carcinoma cell lines EC 9706 were transduced in vitro. The cell apoptosis were determined by flow cytometry, TUNEL technique and DNA fragmentation analysis. Results Ad p27kip1 containing the p27kip1 sequence was successfully constructed and the virus titer was 1.24?10 12 CFU/ml. The transduction efficiency was 100% when multplicity of infection≥50. FCM analysis revealed a sub G 1 cell peak in ad p27kip1 transduced esophageal carcinoma cell lines. Agarose electrophoresis showed marked ladder. The difference of apoptotic index between the ad p27kip1 group and the control group was statistically significant(37.3?3.4 vs. 1.3?0.2, P

Objective To investigate the effects of inhibiting ubiquitin proteasome pathway(UPP) on proliferation of gastric carcinoma cells and the possible mechanism was discussed. Methods The gastric carcinoma cell strain SGC 7901 was treated with MG 132 to inhibit its UPP specially. The effect of growth suppression on cells was evaluated with MTT assay. Cell cycle and apoptosis were detected by flow cytometry(FCM). DNA fragment analysis was used for confirming the presence of apoptosis. The activity of telomerase was examined by TRAP PCR ELISA. Expression of p27kip1 was detected by immunocytochemical technique. Results MG 132 had great inhibitory effect on the growth of SGC 7901 cells. The FCM analysis showed that the ratio of G0/G1 phase of control group was (46.3?4.1)%, the ratio of G0/G1 phase of SGC 7901 cells treated with MG 132 increased to (72.1?5.0)% ( P
