Objective To investigate the effects of procyanidin on apoptosis and caspase-8 activation in HeLa cell induced by TNF-?. Methods Flow cytometry was used to analyze the apoptosis. The caspase-8 fluorescent kits were used to detect the activity of caspase-8. And the expression of caspase-8 enzymogen was examined by Western blot. Results Procyanidin (5, 10, and 20 mg/L) significantly inhibited the apoptosis of HeLa cells induced by rhTNF-? (100 ?g/L) (P

Objective To investigate the feasibility and clinical effect of hip joint arthrodesis with the application of Kirschner wire and reconstruction plate in the treatment of advanced tuberculosis in total hip joint.Methods A total of 30 patients with advanced tuberculosis of the hip in our hospital from March 2014 to April 2016 were divided as Kirschner wire group and reconstruction plate according to different surgical methods,with 15 cases in each group.The operation time,bleeding volume during operation (intraoperative and postoperative),fusion time,postoperative complications of two groups were observed and compared.Results Patients of two groups reached bony fusion.Compared with reconstruction plate group,Kirschner wire group had less blood loss,shorter operative time,longer fusion time,the differences were statistically significant (P ＜ 0.05).Conclusion Both Kirschner wire fixation and reconstruction plate arthrodesis are effective for patients with advanced tuberculosis of total hip joint,but the clinical efficacy of Kirschner wire fixation in hip arthrodesis was significantly better than the reconstruction plate.

Objective To stady the clinical effects of repairing soft tissue defects on body surface by grafting free anterolateral thigh flaps. Methods 11 patients were treated for soft tissue defects on body surface by grafting free anterolateral thigh flaps from October,1986 to January,2002. Results all flaps in the 11 patients survived.Follow-up survey in the (6～18) months after the operation showed satisfactory results. Conclusions Free anterolateral thigh flap is well supplied with blood,and it is in a concealed area of the body,where flaps of large size can be cut off.It is the ideal flap to repair large areas of soft tissue defects on body surface.

OBJECTIVE: To study the mechanisms of the antitumor and immunoregulation functions of polyporus polysaccharide (PPS). METHODS: The production of nitric oxide (NO), the activity and mRNA expression of inducible nitric oxide synthase (iNOS) in peritoneal macrophages of mice administered with different dose of PPS were observed by Griess reaction, fluorimetry assay and RT-PCR, respectively. RESULTS: PPS could elevate the iNOS activity with dose-dependence and stimulate the iNOS mRNA expression of peritoneal macrophages in mice. CONCLUSION: The regulation of PPS on the production of NO in peritoneal macrophages of mice may occur at transcriptional level of iNOS. This indicates that the mechanism of PPS's antitumor and immunoregulation functions may be related to increasing NO output of macrophages through stimulating iNOS's denovo synthesis.

Object To investigate the mechanisms of action of lentinan (LTN) activated mouse peritoneal macrophages to produce nitric oxide (NO). Methods The effects of LTN on NO output and intracellular glutathione (GSH) in mouse peritoneal macrophages and the correlation of them were studied. Results (1) LTN can significantly increase production of NO in mouse peritoneal macrophages, decrease level of intracellular GSH followed increase of NO production. (2) The above effect can be blocked efficiently by the NO production inhibitors. (3) NO production can be inhibited by GSH lowering drugs. Conclusion LTN increase NO production with depletion of intracellular GSH in the activated mouse peritoneal macrophages. It suggested that intracellular GSH plays an important role in regulation of NO production and protection of host cells from cytotoxic attack induced by NO.

Oral anti-viral agents nucleos (t)ide analogues (NAs) are widely used in treatment of chronic hepatitis B (CHB) since they are well-tolerated in most patients.But clinical relapse occurs in a considerable part of patients after the cessation of NAs therapy.This paper reviews factors related to clinical relapse, including time for drug withdrawal, cccDNA level, age, baseline alanine aminotransferase (ALT) and HBV DNA levels, type of NAs, serum level of HBsAg and the immune status of patients.

Objective To optimize the radioligand assays for glutamic acid decarboxylase antibody (GAD-Ab), tyrosine phosphatase antibody (IA-2A) and insulin autoantibody (IAA) and to facilitate their application in clinical practice. Methods The radioligand assays established in our laboratory were optimized in several aspects, including the mode and time of antigen-antibody incubation, pH value of TBST buffer, times of washing, and type of centrifuge. The sensitivity and specificity of the optimized assays were calculated by the Diabetes Antibody Standardization Program (DASP, 2003). And the results were compared to those measured with domestic radioimmune assay kits. Results The optimal condition for radiligand assay were as followed: incubating the antigens of GAD-Ab and IA-2A with serum by rotating slowly for 24 hours and IAA for 72 hours respectively; washing the precipitation complex of GAD-Ab and IA-2A with TBST buffer (pH value 7 2～7 4) 4 times and IAA 5 times respectively; and applying the horizontal type of centrifuge. The results from DASP demonstrated that sensitivity and specificity of the optimized assays were 82% and 98% respectively for GAD-Ab, and 64% and 100% for IA-2A. The proportion of consistency between our results for 82 IAA gradient index of optimized assay and those measured with domestic radioimmune kits was 89%. The extensive analysis showed that the consistency reached 100% for those with IAA index less than 0 04 or more than 1 00, and the inconsistency was for the bordline positive ones (index 0 04～1 0). Conclusion The optimized radioligand assays for islet autoantibodies are high sensitivity and specificity, and are applicable in clinical practice.
