Objective To observe the influence of ATP protection after brachial plexus injuries. Methods A total of 80 female Wistar rats,weighting 280~300 g,were randomly divided into ATP and con- trol groups.The right C_5~T_1 nerve roots were transected and then the intraperitoneal injection of 4m[ of ATP or normal saline was given immediately and once daily to the rats,respectively.The rats were sacrificed on postoperative days 14,28 and 42 respectively.The C_5-T_1 segments of the spinal cord were harvested.NT-3 activity was measured by enzymo-histochemistry method.Four weeks and 6 weeks postoperatively,ultrastruc- ture of the denervated skeletal muscles was observed.Results Compared to the control group,the expres- sions of NT-3 was increased in the treated groups with ATP injection (P

With inlet temperature, specific gravity, feeding speed as independent variables, the comprehensive evaluating indexes of content of schisandrin and arctiin as dependent variable, the experimental data were fitted to a second order polynomial equation. Based on establishing the mathematical relationship between the comprehensive evaluating indexes and respective variables, Box-Benhnken central composite test and response surface analysis method was employed to optimize the spray drying technology of Biqiu granules ethanol extract. The optimal drying parameter was as follows: the inlet temperature was 175 degrees C, the specific gravity was 1.10, feeding speed was 32 r x min(-1). Under these conditions, the comprehensive evaluating indexes of spraying dry processes was 92.68, which was close to the model prediction. The spraying dry technology of Biqiu granules ethanol extract optimized by response surface methodology was accurate and feasible, which provided theoretical experiment basis for the industrialization production.

Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.

Objective To discuss the feasibility and curative effect of broncho-alveolar lavage(BAL)through bronchofiberscope in the treatment of severe toxic pulmonary edema caused by irritative gas.Methods 16 cases se- vere toxic pulmonary edema caused by irritative gas were performed BAL through bronchofiberseope.The index of oxygen in arterial blood,clinical and radiological changes before,during and 2 hours after BAL were observed.Results 2 hours after BAL through bronchofiberscope,the partial pressure of oxygen in arterial blood(PaO2)obviously in- creased,the partial pressure of carbon dioxide in arterial blood(PaCO_2)did not change much.PaO_2 and PaCO_2 had no obvious change before and during BAL.The shadow area in the X-ray film of chest obviously decreased 24 hours af- ter BAL.In all 16 cases,13 cases were cured,1 case got improvement,and 2 cases died.The curative rate was 81%. Conclusion BAL through bronchofiberscope could clear the noxious substance in airway and improve the ventilation function.It was safe and had confirmed curative effect.

Objective: To acquire recombinant nematode anticoagulant peptide ( NAP) with high anticoagulant activity. Methods: Pichia pastoris GS115 strain was transformed with recombinant yeast expression vector pPICS. 5K-rNAP. Expression of rNAP was induced with methanol after the identification of positive strains. NAP expressed in the collected yeast culture supernatant was confirmed with SDS-PAGE and Western blot. The biological activity of the products was validated with PT (prothrombin time) , INR (international normalized ratio) and APTT (activated partial thromboplastin time) , respectively. Results: The yeast strains expressing NAP were identified. The rNAP was secreted into culture supernatant with a molecular weight of about 10 kDa due to glycosylation, which is a little bigger than that predicted (8.7kDa). The anticoagulant efficiency of rNAP was confirmed with the in vitro assays. Conclusion: The recombinant nematode anticoagulant peptide with high biological activity was successfully expressed in Pichia pastoris and can be used in the future development of novel anticoagulant agent.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.
