Objective To observe the intervention effect of Wuxing-Jiangu exercise for different syndrome types of elderly patients with chronic low back pain.Methods A total of 199 patients who met the criteria of chronic low back pain (CLBP) were divided into a Wuxing-Jiangu exercise group (86 cases), a control group (85 cases) and a health education group (28 cases). On the basis of health education, theWuxing-Jiangu exercise group was given Wuxing-Jiangu exercise; the control group was treated with the warm type frequency therapeutic instrument; health education group was only given health education guide. The changes of the score of CLBP patients before and after treatment with different syndrome types were observed.Results After 3 months of treatment, the score of the kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group, the control group and the health education group had significant differences (H were12.554, 8.014, respectively;all P<0.01); After 3 months of treatment, the score of kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group reduced than before the treatment (Z were -5.975,-5.025, respectively)and 1 month after the treatment(Z were -5.976,-5.026, respectively) (all P<0.01).Conclusion Wuxing-Jiangu exercise can reduce the score of the kidney deficiency syndrome and spleen deficiency syndrome and improve clinical syndrome.

Objective:To investigate the influence of dendritic cells modified by hIL-10 on proliferation and cytotoxicity of lymphocyte in experimental animals.Methods:The modified dendritic cells were injected intraperitoneally into C57BL/6 mice to sensitize it. Peripheral blood mononuclear cells (PBMC) of sensitized or unsensitized C57BL/6 mice act as reactive cells, dendritic cells modified or unmodified by hIL-10 act as stimulation cells. These two type cells co-cultured for 6 days. MTT assay was used to detect lymphocyte proliferation. Lactate dehydrogenase release method was used to examine the cytotoxic activity.Results:The results showed that IL-10 can inhibit lymphocyte proliferation reaction of unsensitized or sensitized C57BL/6 mice. Lymphocyte proliferation induced by modified dendritic cells is significant lower than that by unmodified dendritic cells. Modified dendritic cells can resist the cytotoxic activity of cytotoxic T lymphocyte.Conclusion:Dendritic cells stably expressing IL-10 can obviously decrease lymphocyte proliferation response of allogenic mice and reduce the cytotoxic activity.

AIM: To investigate the clinical significance in determination of the P- selectin levels in subjects with prethrombotic state or thrombosis by flow cytometry (FCM). METHODS: The P- selectin expression on platelet membrane in 42 patients with diabetes mellitus, 33 with hyperlipidemia, 23 with cerebral infarction and 20 healthy individuals, were analyzed using fluorescently - labeled SZ - 51 by direct FCM comparing with indirect FCM and enzyme- linked immunosorbent assay (ELISA). RESULTS: The level of P- selectin on platelet membrane is higher in DM (23.92 % + 15.83 % ), in hyperlipidemia ( 18.34 % + 9.46 % ) and in cerebral infarction ( 19.32 % + 10.38 % ) than normal subjects (3.38 % + 1.11% ) ( P < 0.01 ). In addition, similar results on P - selectin were obtained by indirect FCM and ELISA in patients with DM and cerebral infarction. CONCLUSION: FITC - labeled SZ - 51 - IgG can be used in FCM, and it would be a new and sensitive method in detecting platelet activation.

Objective:To study the expression of EG-1 in thyroid cancer tissue and analyze its correlation with clinical prognosis. Methods:EG-1 mRNA levels in malignant thyroid tissues were evaluated by RT-PCR. All patients were followed up. The survival rates were analyze in EG-1 positive group and EG-1 negative group. Benign thyroid tissues were used as control. Results:EG-1 was expressed in thyroid cancer. The differences between expression of malignant thyroid tissues and benign thyroid tissues were statistically significant (P

In recent years, Hepatitis B virus (HBV) persistent infection mouse model with recombinant adeno-associated virus 8 carrying 1.3 copies of HBV genome (rAAV8-1.3HBV) is concerned. We studied and compared the efficacy among HBV persistent infection mice models by other serotypes except AAV8. First, we prepared and purified five viruses: rAAV1-1.3HBV, rAAV2-1.3HBV, rAAV5-1.3HBV, rAAV8-1.3HBV and rAAV9-1.3HBV. Then we injected each virus into 3 C57BL/6J mice with the dose of lx 1011 vg (Viral genome, vg) per mouse. We detected HBsAg and HBeAg in sera by enzyme-linked immunosorbent assay (ELISA) at different time points post injection. We killed mice 8 weeks post injection and took blood and livers for assay. We detected copies of HBV DNA by real-time quantitative PCR in sera and livers. Meantime, we detected HBcAg in the livers of mice by immunohistochemistry and further performed pathology analysis of these livers. The five groups of mice, HBeAg and HBsAg expression sustained 8 weeks in serological detection and HBV DNA was both detected in sera and livers at the time of 8 weeks post injection. HBeAg, HBsAg, HBV DNA copies expression levels in descending order were AAV8>AAV9>AAV1>AAV5>AAV2. HBcAg expression was detected in livers as well. Varied degrees of liver damage were shown in five groups of mice. This study provides more alternative AAV vector species to establish a persistent infection with hepatitis B model.
