Objective: To study the protective roll of neuregulin-1 (NRG-1) on high glucose caused myocardial cell injury in rat’s embryo H9c2 myocardial cells with its mechanism. Methods: Cultured rat’s embryo H9c2 myocardial cells were divided into 5 groups:①Control group,②High glucose (HG) group, containing glucose 33 mmol/L,③HG+NRG-1 10 nmol/L (N1) group,④HG+NRG-1 50 nmol/L (N2) group and⑤HG+NRG-1 250 nmol/L (N3) group. All cells were treated for 24 hours. Myocardial cell survival rate was measured by CCK-8 method, intracellular reactive oxygen species (ROS) level and the apoptosis rate were detected by lfow cytometry, enzymes activities of CK, LDH, SOD and MDA content were examined, proteins expressions of NRG-1 receptor as ErbB2 and ErbB4 were assessed by Western blot analysis. NRG-1 treated myocardial cell apoptosis in type II diabetic cardiomyopathy rats was observed by Tunel staining. Results: Compared with HG group, from N1 group to N3 group, myocardial cell survival rates were increased from (63.33±3.56) %to (85.88±4.55) %, ROS levels decrease form (33.75±4.23) % to (15.88±4.55) %, apoptosis rates reduced from (36.44±4.86) % to (14.77±4.21) %, receptor expressions of ErbB2 was elevated from (0.26±0.04) to (0.84±0.03) and ErbB4 was elevated from (0.39±0.03) to (0.72±0.04), allP<0.05; enzymes activities of CK, LDH and MDA content were gradually decreased and SOD activity was gradually increased, allP<0.05. NRG-1 treated myocardial cell apoptosis in type II diabetic cardiomyopathy rats was also obviously reduced. Conclusion: NRG-1 could increase the survival rate and reduce the oxidative stress injury and apoptosis of cultured rat’s embryo H9c2 myocardial cells in HG condition which might be related to NRG-1 binding to ErbB2/ErbB4 molecules in the cells.

Objective To observe the curative effects and explore the homeostasis mechanism of Fuxueningheji in treating metrorrhagia with blood stasis.Methods 60 patients were divided randomly into test group(30 cases,treated with Fuxueningheji)and control group(30 cases,treated with Gongxuening pulse),one course was 1 month.Results The total effective rate of treatment group was 93.33%,and markedly effective rate was 66.67%,while the control group was 66.67% and 40% respectively.There was no significant difference in total effective rate,but was significant difference in markedly effective rate.Fuxueningheji could improve clinical symptoms of patients obviously and reduced the bleeding and coagulation time,improve the hemorheology,decrease PGI2,increase TXB2.The effects was superior to that of the control group(P

To study the growth, expansion and differentiation of bone marrow stromal cells (BMSC) of rhesus monkey, the BMSC were isolated from adult rhesus monkeys, cultured and induced with a special medium confected in our lab. Identification was performed with immunochemichemistry method. The results showed that BMSC could proliferate and generate clone when culturing in vitro. These cells grow rapidly and differentiated into neuron like cells and astrocyte like cells. The cell clones proliferated from stem cell could express Nestin antigen and the differentiated cells expressing GFAP or NSE antigen respectively. In this study, we did not observe RA, BFGF and EGF remarkably influencing the induction and differentiation of the BMSC. It is suggested that the BMSC from rhesus monkey have the self renewal and differentiation abilities. They might differentiate into neuron like and astrocyte like cells which express GFAP or NSE. As available easily, the BMSC could be considered as the ideal seed cells of the neural stem cells.

Objective To evaluate the therapeutic effect of lentinan combined with conventional antituberculous therapy in women with pelvic tuberculosis.Methods A total of 90 women with pelvic tuberculosis were enrolled and recruited into a control group and a treatment group by random number table,45 in each group.The control group was treated with anti-tuberculosis program (2HRZE/4HRE),while the treatment group was treated with lentinan tablets on the basis of the control group.Both groups were treated for 6 months.Serum levels of carbohydrate antigen 125 (CA125) and erythrocyte sedimentation rates (ESRs) were determined before and after treatment,and the therapeutic effect was evaluated.Results After treatment,the serum CA125 level (28.61 ± 9.08 U/ml vs.39.72 ± 12.13 U/ml;t=4.919,P＜0.01) and the ESR (36.13 ± 8.33 mm/h vs.41.35 ± 12.45 mm/h;t=2.338,P＜0.05) in the treatment group were significantly lower than those in the control group.The negative rate of serum CA125 after treatment than before treatment in the treatment group (93.3％ vs.20.0％;X2=46.335,P＜0.01) and the control group (82.2％ vs.8.9％;X2=37.396,P＜0.01);but there was no difference in negative rate of serum CA125 after treatment between two groups (X2=1.6571,P=0.198).The total effective rate in the treatment group was significantly higher than that in the control group (93.3％ vs.77.8％;X2=4.406,P=0.036).Conclusion Lentinan combined with conventional antituberculous therapy is effective in treatment of pelvic tuberculosis in women.

BACKGROUND:Ligustrazine has been shown to restore the function of the femoral headviathe revascularization, increased blood flow, theabsorption ofnecroticbone, and bone regeneration. OBJECTIVE:To study the effects of ligustrazine on remodeling of periodontal tissues and the expression of osteoprotegerin in the maintenance phase in rats with orthodontic tooth movement. METHODS:Thirty-two healthy male Wistar rats were included and equaly randomized into four groups. Maxilary left first molar mesialization was performed through traction of 50 g force for 21 days to establish the rat model of tooth movement. 5, 10, 15 mg/L ligustrazine (50 μL) were localy injected into the first molar periosteum in model rats on the day before removing the orthodontic forcing device. Same volume of saline was injected in the control group. The injection was administered every other day. At 1 and 4 weeks after injection, the distance of tooth movement, the recurrence distances and percentage were determined and calculated. The pathological changes in periodontal tissues were observed by immunohistochemistry and hematoxylin-eosin staining. The width ofthe parodontium and number of osteoblasts were observed under an optical microscope. RESULTS AND CONCLUSION:The recurrence distance inthecontrol group was increased compared withtheexperimental group, while the number of osteoblasts and osteoprotegerin immunoreactivity were decreased. Good width of the parodontium and smal recurrence trend were found in 10mg/L ligustrazine group. These findings indicate that ligustrazine promotes the proliferation of osteoblasts and enhances the expression of osteoprotegerin, which is beneficial to the retention of teeth after orthodontic surgery.

The build-in low-pressure monolithic column combined with hydride generation atomic fluorescence spectrometry ( HG-AFS ) was employed for speciation analysis of fish meat. The sample pretreatment and separation approach could be accomplished within 30 min. The proper amount of fish sample was weighed and smashed into puree. The extraction solution composed of 10% HCl, 1% thiourea, and 0. 15% KCl was added before loaded into the automatic temperature controlled vertex system with 2000 r/min. The sample solution was separated through Merck monolithic column, with 3% ( V/V) acetonitrile, 30 mmol/L amonium acetate and 0. 03%(V/V) 2-mercaptoethanol (2-ME) as the eluent. The after-column eluent was digested by novel UV digestion device with pipeline sintered into the lamp, and then detected by hydrid-generation AFS. The rapid LC separation enabled fast mercury speciation of fish sample within 10 min. The different UV lamp digestion effects, eluent components, carrier gas, shield gas, lamp current, as well as PMT working power was optimized. Under the optimal conditions, the robust system achieved detection limits (DL) of 0. 15 μg/L and 0. 14 μg/L for methylmercury and HgⅡ, respectively. The RSD (n=7) was less than 5%, the linear correlation coefficient was 0 . 999 , and the matrix spiked recovery was in the range of 85%-110% for Hg speciation. This method was used for the determination of Hg speciation in fish and soil samples, and was proofed to be a reliable, easy approach for daily inspection.
