Objective: To investigate the action and mechanism of Bupleurum chinense SD and Schisandra chinensis Turcz extract on liver fibrosis in rat.Methods: The model was prepared by injection of 40% CCl 4 plant oil solution, then the enzyme active AST、AST、MAO、ALP、r-GT、TG in serum and MAO、ALP、GSH、TG in hemogeneous were measured by enzyme method, the level of Pc-Ⅰand PcⅢ were measured by radio-immunity. Results: Bupleurum chinense and Schisandia chinensis extract can reduce significantly enzyme active of ALT、AST、TG、MAO in serum of fibrosis rat, the GSH was elevated and the r-GT was not effect in serum, but it could reduce the level of MAO、ALP、Pc-Ⅰ、Pc-Ⅲ in the homogeneous, sometime the TG was increased and the GSH was not effect in homogeneous. The histopathology showed that Bupleurum chinense and Schisandia chineusis extract could get damaged liver cell back and reinforce the regeneration of hepatic cell. Conclusion:Bupleurum chinense and Schisandid chinensis extract the action of protective and restoration on injured liver cell, and its could eliminate the bile accumulation, to retard the fatty degeneration in fibrotie rat.

SOX7 belongs to the SOX gene family.And it has been shown to regulate multiple biological processes.Studies have found that SOX7 gene is likely to be a tumor suppressor gene.In many tumors,SOX7 downregulation that inhibits proliferation,migration and invation of tumor via regulating the Wnt-β-catenin signaling pathway mediated the transcription process,which plays a significant role in tumorigenesis.

Objective:To establish an HPLC method for the content determination of salvianolic acid B in Ansheng Yizhi cap-sules. Methods:A Hypersil ODS2 C18 column(150 mm × 4. 6 mm,5 μm) was used and methanol-water-formic acid (40∶60∶1) was used as the mobile phase. The detection wavelength was at 286 nm. The flow rate was 1. 0 ml·min-1 and the sample size was 10 μl. Results:The calibration curve of salvianolic acid B was linear within the range 7. 75-77. 51 μg·ml-1(r=0. 999 6). The average re-covery was 98. 17%(RSD=1. 79%, n=6). Conclusion:The method is simple, accurate and repeatable, which can be used in the quality control of Ansheng Yizhi capsules.

OBJECTIVE To observe a time course of keratinocyte growth factor(KGF) and surfactant protein A(SPA) changes in rats with Pseudomonas aeruginosa pneumonia and to find out the significances of them.METHODS Specific pathogen-free male Sprague-Dawley rats were used to study.Standard P.aeruginosa strain ATCC 27853 was instilled into airway by the tracheal route to induce model of pneumonia.Samples of lung tissue and BALF were harvested before infection,and 6 h,9 h and 72 h after infection.Six rats per each point were sacrificed for harvesting samples.Expression of KGF protein in lungs was detected by Western blotting.Western-dot-blot was used to detect SPA expressions in BALF.RESULTS After infected with P.aeruginosa,KGF protein in lungs was markedly increased,reached the peak at 72 h postinfection.KGF protein level at 72 h postinfection was markedly higher than that of before infection(P

Objective To study the effect of proteasome inhibitor MG-132 on proliferation and apoptosis of human laryngeal squamous cell carcinoma Hep-2 cell line, and to explore if cisplatin (DDP) is combined with MG-132, can enhance the cytotoxicity to laryngocarcinoma cells. Methods Hep-2 cells were treated with different doses (0, 1, 2.5, 5, 10, 20 ?mol/L) of MG-132 for 48h. In another experiment, cells were treated with 2.5?mol/L MG-132 for different length of time (0, 12, 24, 48, 72h). Cells were further divided into 4 groups: control group without any treatment, MG-132 group cells were treated with 1?mol/L MG-132 alone, DDP group were treated with 10, 20, 40 and 80?mol/L DDP alone, and MG-132+DDP group were given 1?mol/L MG-132 combined with 10, 20, 40, 80?mol/L DDP for 48h. Cell growth was assessed by methyl thiazolyl tetrazolium (MTT) assay, and apoptosis was determined with flow cytometry (FCM). Results MTT assays showed that the MG-132 can effectively inhibit the proliferation of Hep-2 cell in a dose-(r=0.944, P

ObjectiveTo analyze the correlations between bone mineral density and biochemistry data of health checkup receivers.MethodsA total of 3025 sets of medical measurements,including blood glucose,lipid profiles,blood uric acid,blood pressure and bone mineral density,were collected from January 2008 to November 2010 in Medical Examination Center of Peking Union Medical College Hospital.Bone mineral density of lumbar vertebra 1 - 4 (L1-4) and hip were recorded.Linear correlation analysis was used to investigate the correlation between bone mineral density and other factors. Results In multiple regression analysis,age,body weight,and alkaline phosphatase level were found to be related to male hip bone mineral density; age,body weight,alkaline phosphatase,and glutamyltranspetidase level were related to male L2-4 bone mineral density; age,body weight,alkaline phosphatase,and glutamyltranspetidase level were indicated to be related to female hip bone mineral density; age,body weight,alkaline phosphatase,and the ratio of neutrophile granulocyte were related to female L2-4 bone mineral density.ConclusionIn thisstudygroup, bodyweightwaspositivelycorrelatedwithbonemineraldensity, although alkalinephosphatase was negatively associated with bone mineral density.The role of blood glucose and lipid in the regulation of bone mineral density remains inconclusive.

Objective To observe the effectiveness of routine nursing plus foot exercise on the peripheral neuropathy and plantar pressure in patients with diabetic foot.Methods Toally 100 patients with diabetic foot were randomly divided into 2 groups.On the basis of routine nursing care,50 patients in the observation group were given foot exercises for 12 weeks,50 patients in the control group were given routine nursing only.Before and after intervention,the Toronto clinical scoring system (TCSS),left and right foot peak pressure variation were observed.Results Before intervention,there was no statistical difference between the two groups' TCSS sore and the peak pressure of left and right foot (P ＞0.05).After intervention,the observation group's average total score of TCSS was lower,there was significantly different between two groups (P＜ 0.001).The peak pressure of left and right foot is lower in the observation group,the difference was statistically significant (P ＜ 0.05).Conclusion Foot exercises is worthy of clinical promotion,because it can improve the peripheral neuropathy of patients with diabetic foot,so as to reduce the plantar pressure,reduce the pain of patients and improve their life quality.

Objective To study the effects of classification-partition-distribution emergency nursing management for severe trauma patients. Method A total of 60 patients from June 2014 to May 2015 were set as control group receiving common nursing and other 62 patients from June 2015 to June 2016 as observation group treated with emergency hierarchical partition and triage nursing. Result The treatment success rate in the observation group were both significantly higher than that of the control group (P<0.05). Conclusion Classification-partition-distribution emergency nursing management for severe trauma patients can increase treatment success rate .

0.3). Conclusions Routine biopsy of donor renal graft is helpful in finding abnormalities as soon as possible.The lesions of donor renal graft may have certain correlation with CAN,but have no association with acute rejection or other abnormalities after renal transplantation.
