Cerebral ischemia activates endogenous angiogenic factors,and increase microvessel density and form new capillaries in ischemic brain tissues.Exogenous angiogenic factors can more effectively promote angiogenesis and the establishment of collateral circulation in ischemic regions and peripherial tissues,improving local blood supply and reducing infarct size.The further study of the mechanisms and methods in promoting regional angiogenesis after cerebral ischemia will contribute to improve neurologic deficit.

Objective To study and analyze the detection significance of platelet indexes and pancreatic blood flow parameters in the patients with severe acute pancreatitis(SAP).Methods Sixty-one patients with SAP in our hospital from June 2014 to June 2016 were selected as the group A,contemporaneous 61 patients with mild acute pancreatitis were selected as group B and 61 persons undergoing the healthy physical examination were selected as the group C.Then the platelet indexes and pancreatic blood flow parameters were detected and compared among 3 groups,and at the same time the platelet indexes and pancreatic blood flow parameters in the group A were compared among different stages of disease course.Results MPV,PDW and platelet activation indexes in the group A were all significantly higher than those in the group B and C,while PCT was lower than that in the group B and group C,the pancreatic head and pancreatic tail blood flow parameters were all worse than those in the group B and C,moreover the pancreatic head and pancreatic tail blood flow parameters in the group B were all worse than those in the group C,and the platelet indexes and pancreatic blood flow parameters in the group A all had significant differences among different stages of disease course (P<0.05),the differences in these indexes were statistically significant.Conclusion The detection significance of platelet indexes and pancreatic blood flow parameters in the patients with SAP is higher,and also has a certain value for the disease course stages in the patients with SAP,so their monitoring has higher value.

Objective:To establish the high performance liquid chromatography (HPLC) combined with switching wavelength method to determinate chlorogenic acid, ferulic acid, Calycosin-7-glucoside in Shenqi-Yiqi oral liquid. Methods:The Shenqi-Yiqi oral liquid was separated on an Agilent HC-C18 column by gradient elution using acetonitrile (A) - 0.1% phosphate (B) as the mobile phase. The flow rate was 1.0 ml/min. The detection wavelengths were 260 nm (chlorogenic acid and Calycosin-7-glucoside), 316 nm (ferulic acid) by wavelength conversion method. Results:The linear ranges of chlorogenic acid, ferulic acid, Calycosin-7-glucoside were 70.40-704.00 μg ( r=0.999 8), 1.36-13.60 μg ( r=0.999 8), 1.28-12.80 μg ( r=0.999 7), the average recovery rate were 99.44% ( RSD=2.54%), 101.06% ( RSD=1.57%), and 98.00% ( RSD=2.09%). Conclusion:This method is convient, rapid and accurate for determinating chlorogenic acid, ferulic acid and Calycosin-7-glucoside in Shenqi-Yiqi oral liquid.

Objective:To study the positive expression rate of M2 subtype of macrophage cell surface molecules and the inflammatory factors of PPS in IL-4-induced M2 macrophage.Methods:The experiment was divided into 5 groups:blank control group, Model group,PPS groups(50 μg/ml,100 μg/ml and 200 μg/ml).The expression of CD206 and CD23 was used as bio-maker to confirm IL-4 induced macrophages by treating RAW264.7 with 20ng/ml of IL-4.IL-4 induced RAW264.7 cells were treated with PPS of 50μg/ml,100μg/ml and 200μg/ml for 24 h.Then the expression of CD206,CD16/32 and CD40 were analyzed by flow cytometry, and the mRNA expression of IL-1β,TNF-α,IL-10 and iNOS were detect by qRT-PCR.Results: After treated with IL-4,the positive rate of CD206 of RAW264.7 were high.After treated with PPS ,the rate of CD16/32 and CD40 in IL-4 induced RAW264.7 cells were high ,the expression of CD206 decreased,and the mRNA level of IL-1βand TNF-αincreased.Conclusion:RAW264.7 cells can be polarlized to M2 subtype macrophage by using 20 ng/ml IL-4.PPS enhances the mRNA of IL-1β,TNF-αand the expression of CD40, CD16/32 in IL-4-induced RAW264.7 cells .These results indicate that PPS can induce the M2 subtype to become M1 macrophages, can improve immune function of macrophages.

The effect of carbon source,nitrogen source,temperature,moisture,pH and light on the fungal growth,conidia production and conidia germination of Paecilomyces cicadae LB were studied.For the fun-gal growth and conidia production,the optimum carbon sources were soluble starch and glucose,while the optimum nitrogen source was peptone.For the fungal growth and spore germination of P.cicadae,the opti-mum temperature was 25?C~27?C,for the conidia production,the optimum temperature was 25?C.Conidia geminated at RH 90%~100%,but did not below 90%.When RH reaches to 100% or the conidia were in wa-ter,the germination rate was the highest.The range of pH for the fungal growth,conidia production and co-nidial germination was 4~10,while the optimum pH for the fungal growth was 6 and 6~7 for the conidia production and conidial germination.The light treatment significantly influenced fungal conidia production.The lethal temperature for the fungal conidia was 55?C remaining 10 minutes.The present results suggest the isolate LB can adapt to nutrition and environment more widely,and has greater potential as biological control factor against of pest.

Objective:To improve the safety,rationality and efficacy of medication for ovarian cancer patients complicated with cirrhosis by the participation of clinical pharmacists in the therapy. Methods:Clinical pharmacists participated in the therapy for an ovarian cancer patient with cirrhosis,and provided a rational and individualized therapeutic regimen through the drug experience of clinical pharmacists as well as the relevant medical guides and literatures. Results:The therapeutic efficacy was increased by the participation of clinical pharmacists in the therapy,the potential risk of the chemotherapy was avoided and the security of medication was assured. Conclusion:The participation of clinical pharmacists in therapeutic practice can improve the normalization of pharmacotherapy for ovarian cancer patients with cirrhosis,which also can provide ideas and methods for treating the similar patients.

Clinical neuroanatomy is a bridge between basic medicine and clinic. To resolve the deficiency existing in PBL teaching,we improved the basic teaching installation and teaching practice and evaluation system. The results indicated that we had gotten satisfactory effect by using teaching method of clinical neuroanatomy

Objective:To understand the clinical diagnosis and treatment ability of Chinese and French medical students, so as to improve the education of clinical medicine in China, improve the diagnosis and treatment ability of medical students, and provide reference for improving training quality of medical personnel.Methods:Retrospective analysis was made on the clinical skills competition of Chinese and French medical students, and the percentages of three categories of students' scores were compared (1 team of general practice residents, 3 teams of Chinese undergraduates, and 3 teams of French undergraduates).Results:In clinical basic skills such as electrocardiogram and imaging interpretation site, the scores of general practice residents were higher than those of Chinese and French undergraduates, and there was no significant difference between Chinese and French undergraduates. In clinical virtual case sites, except for few items in surgery site, general practice residents and Chinese undergraduates were better than French undergraduates in many evaluation items. In the internal medicine site, 6 out of 8 scoring items of French undergraduates were higher than those of Chinese undergraduates. In the medical team comprehensive first-aid site, 8 out of 10 scoring items of Chinese undergraduates were higher than those of French undergraduates.Conclusion:Clinical thinking and decision-making of undergraduates in our university need to be improved compared with that of French students. The general practice residents in our school need to be strengthened in the aspects of clinical thinking, decision-making and the cooperation with emergency team.
