Objective To investigate T cell-mediated anti-HBV effects of dendritic cells (DCs) sensitized by HBsAg in patients with HBV infection in vitro. Methods DCs isolated from peripheral blood mononuclear cells of HBV patients were cultured and proliferated in vitro, and then were stimulated with pure HBsAg before DCs maturation, and co-cultured with auto-T lymphocytes after DCs maturation. The T lymphocytes were then harvested 5 days later and added into the supernatant of 2.2.15 cell cultures. The supernatants were collected on 1st, 3rd, 5th and 7th day, respectively. ELISA was employed to detect HBeAg and the secretion of HBsAg, as well as to measure the concentration of IFN-? and IL-12 in culture supernatents. Results The proliferation and cytotoxicity of auto-T cells were markedly enhanced in the antigen stimulated DCs group compared with that of DCs without loaded antigen and only T lymphocyte group (P

Objective To identify the property and implications of dendritic cells of peripheral blood monocytes (PBMC) in patients with persistent HBV infection. Methods The PBMC from 18 patients with persistent HBV infection and 10 healthy subjects were incubated and induced into mature dendritic cells (DC) in the completed medium containing GM CSF、IL 4、FLt3 L and TNF ? cytokines. The flow cytometric analysis was employed to detect the expression of surface markers on DC. ELISA test was used to determine the level of interleukin 12 (IL 12) and IL 10 cytokines produced by DCs. The stimulatory capacity of DC were also determined in allogenic mixed leukocyte reaction (MLR). Results A typical morphology of DCs was observed when the PBMCs from healthy subjects and HBV infected patients were induced for 6 7 day in vitro incubation, but there were some significant differences of DCs as follows: (1) the proliferation ability and number of DCs significantly decreased, in particular, the expression levels of HLA DR,CD80(B7 1),CD86(B7 2) and CD1? on DC surface were simultaneously much lower in patients compared to healthy subjects ( P

Objective To investigate the relationship between body mass index (BMI) and dose area product (DAP) as well as fluoroscopy time during coronary angiography (CAG) in Han nationality subjects in order to improve early judging and reducing high radiation risk. Methods CAG materials of 451 Han nationality subjects were retrospectively analyzed. The patients included 276 males (age 32-87 years) and 175 females (age 42-84 years), and the BMI values ranged from 17.30 to 35.42 kg/m2. According to BMI values, the patients were divided into group A(BMI<20 kg/m2,n=25), group B (BMI 20-24.9 kg/m2,n=204), group C (BMI 25-29.9 kg/m2,n=192) and group D (BMI>30 kg/m2,n=30). The mean DAP and fluoroscopy time of each group were calculated; the DAP values were compared between each other among the four groups by using nonparametric Kruskal-Wallis test, while the fluoroscopy time was compared between each other among the four groups by using single factor analysis of variance or LSD-t test. Results The mean DAP of group A, B, C and D was(1 070.07±541.33) μGym2,(1 326.82±606.91) μGym2,(1 937.99±1 030.31) μGym2 and (2 654.53±1 296.69) μGym2 respectively. The mean fluoroscopy time of group A, B, C and D was (3.53± 2.08) min, (2.70 ±1.80) min, (2.75 ±1.88) min and (2.71 ±1.69) min respectively. Statistically significant difference in DAP values existed between each other among the four groups (P<0.05) except between group A and group B (P=0.232). Statistically significant difference in fluoroscopy time existed between group A and other three groups (P<0.05), while the difference in fluoroscopy time between each other among B, C and D groups was not significant (P>0.05). Conclusion The DAP values of adult Han subjects receiving CAG are increased with the increase of BMI values; the fluoroscopy time is significantly prolonged in patients with BMI<20 kg/m2. In performing interventional procedure, the operator should not only understand that the increase of BMI can cause the increase of DAP, but also need to pay special attention to the increase of DAP value caused by operation difficulty when the patient’s BMI is <20 kg/m2.

BACKGROUND:Intervertebral disc degeneration is the basis of spinal degenerative diseases;however,there is no effective treatment. OBJECTIVE:To investigate whether sinomenine can inhibit interleukin-1β-induced apoptosis in nucleus pulposus cells and its molecular mechanism. METHODS:Rat nucleus pulposus cells were cultured in vitro by trypsin combined with type II collagenase digestion,and the cell growth curve was plotted.An appropriate sinomenine concentration was determined using the cell counting kit-8 kit.Nucleus pulposus cells were divided into control group,sinomenine group,interleukin-1β group,sinomenine+interleukin-1β group,zinc protoporphyrin group,zinc protoporphyrin+sinomenine group,zinc protoporphyrin+interleukin-1β group,and sinomenine+zinc protoporphyrin+interleukin-1β group.Proliferative activity,reactive oxygen species content,apoptosis rate,and heme oxygenase-1 expression in nucleus pulposus cells were detected. RESULTS AND CONCLUSION:The rat nucleus pulposus cells cultured in vitro were polygonal,triangular,and short wedge-shaped,and the cell growth showed an"S"curve.The cells grew slowly in the first 3 days of culture,rapidly in 4-6 days,and slowly again in 7-8 days.The cells then entered the"platform stage"where the number of cells no longer increased.The proliferative activity of myeloid cells showed no significant changes when the concentration of sinomenine was≤80 μmol/L(P>0.05).Interleukin-1β significantly reduced the proliferative activity of nucleus pulposus cells,increased the content of reactive oxygen species and led to apoptosis(P<0.01).Sinomenine intervention not only promoted heme oxygenase-1 expression(P<0.05)but also inhibited interleukin-1β-induced decrease in proliferative activity and increase in reactive oxygen species content and apoptosis rate in nucleus pulposus cells(P<0.05).These effects could be reversed by zinc protoporphyrin(P<0.01).
