Objective To investigate the effects of new compound traditional Chinese medicine prepatations Banxiao capsule on the mobilization of endothelial progenitor cells ( EPCs) .Methods After EPCs from mouse bone marrow treated with variable dose of Banxiao capsule, we detected the proliferation by CCK-8 assay, quantified the number of CD34/Flk-1 double positive cells by flow cytometric analysis, evaluated the migratory function of EPCs by transwell chamber assay, and studied the protein level of Bcl-2/Bax by Western blot analysis.Results Compared with untreated group, the proliferation potential of EPCs in Banxiao low dose (20μg/ml) and high dose (200μg/ml) group was increased(P<0.05), the number of CD34/Flk-1 double positive cells were increased (P<0.05), migrative activity of EPCs was increased (P<0.05),the level of Bcl-2 protein were increased, and the level of Bax protein were decreased.Con-clusion Banxiao capsule can enhance proliferation of EPCs through up-regulating of expression of Bcl-2/Bax.

Objective To estabilish a HPLC method for the determination of Geniposide in Jigucao Capsule. Methods The column was Lichrospher-C18(5 ?m,4.6 mm?250 mm). The determination was carried out with acetonitrile-0.1% phosphoric acid(10∶90) as the mobile phase,a flow rate of 1.0 mL/min and detected at 238 nm,and temperature of the column was 35 ℃. Results The calibration curve showed good linearity in the range of 0.14～1.68 ?g,Y =1 552.15X-6.42,r=0.999 9. The mean recovery was 97.53%(RSD=1.24%,n =6). Conclusion The method is accurate,reliable,and can be used for quality control of the preparation.

Objective: To propose the hypothesis of "endogenous collateral wind" based on the pathomechanism of thrombogenesis complicated by ruptured plaque on acute coronary syndrome(ACS) and the theory of traditional Chinese medicine.Methods: Patients of coronary artery disease with successful coronary angiography(CAG) and intravascular ultrasound(IVUS) was made the differential diagnosis such as blood stasis,blood stasis due to phlegm obstruction and endogenous collateral wind.The levels of plasma inflammatory marker were measured to study the charactristic of "endogenous collateral wind".The prescription principle of Luoheng dripping pills was promoting blood circulation to expel wind-evil and remove wetness under guidence of "endogenous collateral wind" hypothesis.Patients with unstable angina were randomly divided into 3 groups based on therapeutic methods:conventional therapy group,luoheng dripping pills group and Tongxinluo capsule group.Results: There were characteristic changes of severity of coronary artery stenosis,the types of ACC/AHA lesion and Levin lesion,remodeling index,positive or negative remodeling percentage measured by IVUS,the plasma levels of plasma inflammatory marker measured by ELLSA in patients with endogenous collateral wind syndrome.The total effective rate of improved angina in luoheng dripping pills group was significantly higher than those in other two groups.The levels of plasma inflammatory marker were significantly lower in luoheng dripping pills group.Conclusion: There were some pathological found of the hypothesis of "endogenous collateral wind" on acute coronary syndrome.It provides the evidences that patients with coronary artery disease were treated with expelling wind-evil and removing wetness.

Great and extensive progress has been made in joint surgery in the last decade. With the evolution of surgical concepts and the development of operational technique and equipment, indications, selective range for surgica l operation and management in the period of perioperation have been surveyed in new perspectives and with deeper insights. This article introduces the situation of joint surgery of China in these years, briefly reviews the latest progresses in the fields of the arthroscopy, the arthroplasty and the joint cartilage repa ration, and thus suggests developmental strategies for Chinese joint surgery in the future.

Abstract: Objective　To analyze the whole genome characteristic of influenza A(H1N1) pdm09 virus outbreak in a school in Jining, so as to serve as a reference for prevention and control of influenza A (H1N1) pdm09．Methods　Real time fluorescence quantitative PCR were used to detected the 12 nasopharyngeal swab specimens from patients. The positive specimens were cultured and sequenced the whole genome. DNASTAR was used to analyze the homology. MEGA was used to construct the phylogenetic tree. NetNGly, GPS-SUMO, NetPhos were used to predict the glycosylation sites, the small ubiquitin-like modifier sites and the phosphorylation sites respectively. Results　Among of 12 specimens, 4 specimens were showed positive for influenza A (H1N1) pdm09 virus nucleic acid, and 4 virus strains were isolated. Compared to the vaccine strain A/Brisbane/02/2018, the homology of nucleic acids of 8 gene segments was 98.5%-99.8%. The homology of amino acids of 10 proteins was 98.2%-100%. In the evolutionary tree analysis, four strains were located in two evolutionary clusters, three strains in the same evolutionary cluster and one strain in a different evolutionary cluster. A total of 50 amino acid site substitutions occurred in the 10 proteins encoded by the four strains, including two amino acid sites in the hemagglutinin antigen epitope, and there was no mutation in the neuraminidase (NA) protease active site, polymerase acidic protein (PA), polymerase basic protein 1 (PB1) and polymerase basic protein 2 (PB2) inhibitor resistance sites, and neuraminidase inhibitor resistance sites. In addition, the glycosylation sites and SUMO sites were not mutated, while multiple phosphorylation sites were substituted. Conclusions　There are 2 different sources of influenza A (H1N1) virus causing the school influenza outbreak. School influenza outbreak surveillance and school influenza prevention and control should be strengthened should be enhanced.

Objective To observe the time interval changes of the expression of Nogo-A in the intumescentia lumbalis of rats with experimental allergic encephalomyelitis(EAE),and explore the function of Nogo-A in the happening and development of EAE.Methods One hundred and six Wistar rats(female) were randomly divided into 2 groups:EAE group(70 rats)and control group(36 rats).Female Wistar rats were used to make EAE animal models,immunized by fresh cavia cobaya spinal cord homogenate and complete Freund adjuvant(CFA),at the same time,their blood brain barrier permeability was lifted by using pertussis stock solution.The rats those were coincident with the standard of being picked up were divided into 6 groups randomly according to the time of falling ill.In control group,fresh guinea pig spinal cord homogenate was replaced by sodium chloride,and rats were also divided into 6 groups randomly.Immunohistochemistry SP was used to detect expression of Nogo-A.Amyelination was detected by improved acid fuchsin and azulin myelin staining.Results In the control group,differences of Nogo-A expression in the intumescentia lumbalis were not obvious in each time group.In the EAE group,expression of Nogo-A could be observed in each time group,but their quantities were very different in contrast with those in the control group.One day after the rats had clinic symptoms,the expression of Nogo-A decreased to some extent;the third day,it reached the lowest point,and was significantly lower than that in control group(P
