OBJECTIVE: To evaluate the role of total glucosides of peony (TGP) as adjuvant therapy for prevention of cardiac allograft rejection in rats. METHODS: Rats with cardiac allograft were randomly divided into control group, tacrolimus-treated group, TGP-treated group and tacrolimus plus TGP-treated group. Graft survival time was observed. Allografts in some cases were examined by histological study seven days after transplantation. At the same time, the levels of CD4(+) and CD8(+) T cell subsets in peripheral blood were examined by using flow cytometry; the hepatic function and renal function of recipients were also tested. RESULTS: The graft survival time of the tacrolimus-treated group and tacrolimus plus TGP-treated group was (11.14+/-1.57) d and (13.57+/-1.99) d, respectively. The graft survival time of the tacrolimus plus TGP-treated group was longer than that of the tacrolimus-treated group (P<0.05). The histological study showed that the rejection of the tacrolimus plus TGP-treated group was slighter than that of the tacrolimus-treated group. The levels of CD4(+) T cell subset in the peripheral blood of the tacrolimus-treated and tacrolimus plus TGP-treated groups were (38.71+/-5.15)% and (32.43+/-4.39)% respectively 7 days after transplantation. The level of CD4(+) T cell subset in the tacrolimus plus TGP-treated group was lower than that in the tacrolimus-treated group (P<0.05). The level of CD8(+) T cell subset and the hepatic and renal function had no significant differences between the tacrolimus-treated group and the tacrolimus plus TGP-treated group. CONCLUSION: Effects of tacrolimus plus TGP in prevention of rejection are better than tacrolimus monotherapy in rats with cardiac allograft and without increasing side effects.

OBJECTIVE:To work out the optimal inventory levels in zero inventory management mode through model predic-tion and control strategy,by using the inventory upper & lower limits settings generally available in the information management system of health care institutions. METHODS:Multi-varieties joint ordering modelwas constructed by referring to operations management,time series analysis and quantitative approach to decision-making,that is,to make a prediction of upper&lower lim-its on medicine inventory based on historical data and applicable mathematical models(fixed order interval model and re-order mod-el,i.e. FOI and ROP),and compared with real results;based on above,specific medicine procurement and inventory control strat-egies would be developed and an evaluation of the application effects would be made. RESULTS:The error test and reproducibility test exhibited that the out-of-stock ratio remained under 3.36%,of which 71.24% could be effectively alarmed;under computer simulation and practical operation,the instant replenishment rate reduced by 9.33% and 13.03%,OOS ratio down by 11.11% and 27.45%,and average daily inventory turnover rate up by 30.19% and 15.85% respectively,all showing remarkable improvements compared to before the implementation of the mode. CONCLUSIONS:This model is of favorable accuracy and operability,there-fore it can lay foundation for rational and well-founded decisions in medicine procurement and inventory control in zero inventory management mode.

AIM: To study the relationship between prostaglandins and acute pulpitis. METHODS: Rat traumatic pulpitis model was established by pulp exposure. The kinetic pathological changes in dental pulpal tissues and changes of PGE 2?6-Keto-PGF 1? and TXB 2 concentration in dental pulp were observed. RESULTS: After pulpal trauma, the dental pulp showed inflammatory changes and the concentrations of PGE 2?6-Keto-PGF 1? and TXB 2 were increased, which peaked at 6 hour post-trauma. CONCLUSION: Prostaglandins play a significant role in the pathogenesis of pulpitis.

Objective:To investigate the effects of laparoscopy assisted complete mesocolon resection on the stress response and immune function of patients with colon cancer.Methods:From January 2013 to January 2016,130 patients with colon cancer in our hospital were selected and randomly divided into the observation group and the control group with 65 cases in each group according to the random lottery envelopes.The observation group was treated with laparoscopy assisted complete mesocolon resection,the control group was treated with open operation.The changes of semm IL-6,TNF-α and amours of CD4+ cells,blood loss,bowel function restoration time,hospital stays and complication rate of two groups were compared before and after treatment.Results:Both groups of patients were successfully completed the surgery and there was no serious complications occurred in both groups.The amount of bleeding,postoperative intestinal recovery time and postoperative hospital stay in the observation group were significantly less than those of the control group (P＜0.05).The chylous fistula,wound infection,pulmonary infection and complication rate on the 14th day postoperation in the observation group was 1.5％,which was 12.3％ in the control group and significantly higher than that of the control group (P＜0.05).The contents ofCD4+ cells in the observation group and the control group were 36.34± 7.83％ and 33.66± 9.82％,respectively,which were significantly higher than those before treatment(30.33± 6.49％ and 30.49± 5.33％)(P＜0.05),and the contents of CD4+ cells of observation group was significantly higher than that of the control group after treatment (P＜0.05).The serum levels ofIL-6 and TNF-α in both groups were significantly lower than those before treatment on the 14th day postoperation (P＜0.05),and the serum IL-6 and TNF-α levels of observation group were significantly lower than those in the control group on the 14th day postoperation (P＜0.05).Conclusion:Laparoscopy assisted complete mesocolon resection could promote the immune function and inhibit the stress response,which further promoted the rehabilitation and induced the complications in the treatment of patients with colon cancer.
