Objective: To study the regulatory action of BushenqingreFang on Fas/FasL in the cells of nephridial tissue in mice with lupus nephritis (LN) caused by chronic graft-versus-host disease (cGVHD). Methods: To observe the apoptosis in nephridial tissue by TUNEL and to measure the Fas/FasL genetic transcription and their protein expression by immunohistochemistry, western blot and RT-PCR techniques. Results: BushenqingreFang increased the positive score of TUNEL in nephridial tissue and up regulated mRNA expression and protein levels of Fas and FasL. Conclusion: The action of BushenqingreFang on LN may be conducted by its up regulation of Fas and FasL and its promotion of apoptosis.

Objective To investigate the effect of rAAV2 VEGF 165 (recombinant adeno associated Virus 2 vector encoding VEGF 165 cDNA) in stimulating angiogenesis, its dose effect relationship in swine acute coronary occlusion model, and to search for a suitable dose for further investigation in swine myocardium ischemia model Methods Ligation of LAD (left anterior descending coronary artery) was performed in swine modles via mini thoracotomy rAAV2 VEGF 165 (experimental group) or phosphate buffer saline (control group) was injected around the infarcted region The experimental group was divided into four subgroups: according to the amount of virus genome, which were: 1?10 11 v g (virus genome), 5?10 11 v g, 1?10 12 v g and 5?10 12 v g Animals underwent angiographic evaluation of collateral development four weeks after the operation Expression of VEGF was assessed by semiquantitative RT PCR and immunohistochemical staining Results Four weeks after the operation, expression of VEGF was detected in all the four experimental subgroups and the level of expression was higher than that of the control group Capillary density was higher in both of the 1?10 12 v g and 5?10 12 v g subgroups, compared with the control Coronary angiography demonstrated higher collateral index to the occluded LAD in the groups of 5?10 11 v g,1?10 12 v g and 5?10 12 v g than that of the control Conclusion Direct injection of rAAV2 VEGF 165 can achieve effective expression of VEGF in swine acute ischemic myocardium At certain dosage, rAAV2 VEGF 165 can promote generation of blood ressels in swine acute ischemic myocardium and 1? 10 12 v g is a more suitable dosage for swine myocardium ischemia model

Objective Evaluation of the benefit and safety of combined thrombolysis and precutaneous coronary intervention in acute myocardial infarction by retrospective analysis. Methods Precutaneous coronary intervention were performed in 45 patients with acute myocardial infarction immediately after thrombolysis. The clinical and angiographic data were compared with that of 31 patients with thrombolysis alone and 74 patients with primary precutaneous coronary intervention in the same period. Results Angiographic data showed that patients with PCI plus thrombolysis had more frequency of TIMI 3 flow than patients with thrombolysis alone (88.9% vs. 74.2%, P=0.087). Patients with PCI plus thrombolysis and with primary PCI had similar frequency of TIMI 3 flow (88.9% vs. 91.9% P=0.404). Clinical data showed that patients with PCI plus thrombolysis had less major adverse cardiovascular events in hospital than patients with thrombolysis alone (4.4% vs. 12.9%, P=0.181). Patients with PCI plus thrombolysis and with primary PCI had similar major adverse cardiovascular events (4.4% vs. 1.4%, P=0.319). Patients with three strategies of treatment had similar mortality (4.4% vs. 6.5% vs. 4.1%). Patients with three strategies of treatment had similar major bleeding events (4.4% vs. 3.2% vs. 1.4%) in hospital. Conclusion Combined thrombolysis and precutaneous coronary intervention maybe surpass thrombolysis alone, at least similar to primary PCI. This strategy of treatment is safe.

A quantitative study on human water contact was carried out in an endemic area of schistosomiasis japonica. The information relating to frequency, duration and intensity of each activities was obtained from 390 persons (93% of all) aged 5-59 and 10 days of each season in 1987 was surveyed by using systematic sampling. Socioeconomic investigation and stool examination were also performed on the same population. It is found that cutting grass and fishing are the most important activities, as well as swimming and bathing. The accumulated index ofexposure is high in spring and summer, low in autumn and rare in winter. The peak contact is 8-12 o'clock in the morning. The reasons of contact are different between males and females. And the peak contact is at teen aged youth. Studies on water contact and socioeconomic factors show that there are more contacts in peasants than in those with other occupations. Rich farmers who has more savings contact less. The contacts seem more frequent in those whose family water supply is from infected water. The stepwise regression analysis shows that the most important factor relating to the infection of schistosomiasis japonica are index B of exposure (accumulation of duration ? intensity). The infected water supply of family and education were two other factors relating to the infection.

OBJECTIVE:To establish the quality standard for Compound huaihua granules.METHODS:Sophora japonica,salvia miltiorrhiza,and Lonicera joponica in the formulation were identified qualitatively by TLC,and the content of rutin in Sophora japonica was determined by UV spectrophotometry.RESULTS: The TLC spots were clear and well-separated.The linear range of rutin was 2.904～14.52 ?g?mL-1(r=0.997 7) and its average recovery was 98.43%(RSD=0.55%,n=6).CONCLUSION: The established standard is suitable for the quality control of Compound huaihua granules.

Objective:To evaluate the clinical efficacy between preparation porcelain veneer(PPV)and no-preparation porcelain veneer(NPPV).Methods:44 patients with 97 PPVs and 23 patients with 57 NPPVs were followed up for 3 years.Mental tension, postoperative dentin sensitivity and satisfaction of the patients,survival rate of the veneers,sulcus bleeding index(SBI)of preopera-tive and postoperative 3 years were evaluated.A comparative analysis was taken to examine the clinical indicators of 2 groups accord-ing to the modified CDA /Ryge criteria.Results:Survival rates of PPVs and NPPVs were 96.91 % and 96.49%(P >0.05),satisfac-tion rates of the 2 group patients were 95.45% and 95.65%(P >0.05),respectively.Mental tension and the postoperative dentin sensitivity of patients in PPV group was higher than those in NPPV group.Preoperative and postoperative SBI were not statistically dif-ferent between the 2 groups(P >0.05).Marginal adaptation in PPV group was better than that in NPPV group.Color matching, Porcelain surface and Marginal stain were not statistically different between 2 groups.Conclusion:Preparation porcelain veneers and no-preparation porcelain veneers both are effective in clinical application.
