Objective To study the role of bacterial collagenase in wound healing with observing capillary neovascularization, epidermis regeneration and collagen fiber reparation in vivo. Method A total of 28 New Zealand rabbits were made into models of superficial soft tissue trauma and divided into two groups. In the experimental group, the right limbs of rabbits were traumatized intentionally in the same length and depth, and their wounds were treated with bacterial collagenase liquor 133 MIU/mL, and the wounds were sutured. Similarly, in the control group, the left limbs of the rabbits were modeled in the same way and their wounds were managed with physiological saline instead and closed. Their wounds were observed continually 1, 2, 3, 5, 7, 10 and 14 days after traumatized. Data were analyzed statistically by using One-way ANOVA, LSD-test, and Wilcoxon rank test. Results There were no significant differences in capillary neovascularization and epidermis regeneration between two groups ( F = 0.12, P = 0.740 and F = 0.95, P = 0.33, respectively), but significant difference in collagen fiber reparation was found between two groups (F = 6.63, P = 0.01). Conclusions In the progress of wound healing, bacterial collagenase can improve the collagen fiber reparation without effects on the new capillary vasculogenesis and epidermis regeneration. The bacterial collagenase does not play a positive role in wound healing.

[Objective]To ascertain the best formulation process of Tangkening Granule. [Method]By determinating hygroscopicity, granulation and dissolubility, the appropriate recipient and its formula are selected. [Results]The best excipient is 1∶0.5. The made granules have low hygroscopicity and high granulation and high dissolubility. And its critical relative humidity is 70%. [Conclusion]The experimental results provide the basis of the ascertainment of formulation process and the control of product inviroment of Tangkening Granule.

Objective To investigate the mechanism of glycoprotein serglycin (SRGN) promoting metastasis of breast cancer cells and the possible mechanism of SRGN expression.Methods Real time quantitative polymerase chain reaction (PCR) and bioinformation retrieval were used to detect the expression of SRGN in lymph node metastasis and non-metastasis breast cancer.MDA-MB-231 shRNA and MCF-7-SRGN of breast cancer stable cell line were established by lentivirus shRNA interferencc and overexpression.Transwell assay was used to test the effect of SRGN on invasion and metastasis of breast cancer cell line in vitro.Western blot assay was used to detect the changes of epithelial-mesenchymal (EMT) related markers.The possible regulatory mechanism of SRGN expression was detected by Western blot assay.Results SRGN expression was significantly increased in lymph node metastasis of breast cancer in clinical specimens.SRGN interference inhibited the invasion and metastasis of tumor cells.SRGN promoted breast cancer cells EMT.Transforming growth factor β1 (TGFβ1) promoted the expression of beta SRGN transcription.Conclusions SRGN can induce the change of EMT in breast cancer cells and promote the invasion and metastasis of breast cancer cells.

Simulated teaching method is a necessary complement to theoretical teaching of health law,which meets the practical-oriented reform need and cultivates students with the literacy as a legal professional.The teaching method demands more requirements on teachers,students,teaching materials,organizational management,and more attention on contextual design,preparation details,implementation activities and evaluation of teaching.

Constructivism educational theory can provide a useful guidelines for health law education,this article finds the association of constructivist theory for health law education reform,and combined the with application of relevant theories on teaching practice experience,it also discusses how to provide a real promotion for the"students'first"concept.

Objective To observe the effectiveness and safety of basal insulin plus oral antidiabetic drugs (OADs) in treating the patients with type 2 diabetic mellitus (T2DM ) ,who were poor blood sugar control by premixed insulin with or without OADs . Methods 32 cases of T2DM and poor blood sugar control by premixed insulin combinated with or without OADs stopped the premixed insulin therapy and changed to insulin glargine plus OADs for 16 weeks .Glycosylated haemoglobin (HbA1c) ,fasting blood glucose(FBG) ,postprandial blood glucose(PBG) ,body mass index (BMI) and mean daily insulin dose were compared among patients .And the episodes of hypoglycemia events were recorded .Results After 16‐week treatment ,HbA1c ,FBG ,PBG and BMI were all significantly decreased comapared with before treatment (P<0 .01) .The mean insulin glargine daily dose was significantly decreased compared with the premixed insulin dose at admission .2 cases (6% )appeared twice hypoglycemia episodes during the treatment period ,all were general hypoglycemia .Conclusion Basal insulin once daily can effectively improve the sugar metabolism in T2DM patients failed by premixed insulin with or without OADs ,moreover the body mass is not increased .

Ureaplasma urealyticum(UU)is one of the most common pathogen in childbearing age women.The proportion of neonate especially premature baby infected with UU is increasing yearly.UU infaction is related with premature labour,low birth weight,bronchopulmonary dysplasia,chronic lung disease,respiratory distress syndrome and other perinatal diseases by promoted the expression of inflammatory cytokines,increasing the inflammatory response and interfering inflammation clear.There still has controversial point to treat perinatal diseases caused by UU infection by erythromycin,azithromycin,pulmonary surfactant,steroid.

ObjectiveTo evaluate the reliability and validity of the of Disability Assessment Schedule Ⅱ of World Health Organization(WHO-DASⅡ) applied in assessment of the function of disabled athletes.Methods56 disabled people,26 wheelchair basketball athletes and 30 patients,were sampled and completed WHO-DASⅡ questionnaire.The test and re-test had been administrated in 10 days.Barthel Index(BI) and Sports Classification Test had been implemented for the functioning assessment.ResultsThe test-retest reliability for WHO-DASⅡ in six dimensions were: 0.978,0.807,0.938,0.877,0.998,0.935,0.986 and all were in very significant level(P<0.01).There were negative correlation between WHO-DASⅡ scores and BI in total and in every dimension,the correlation coefficients were:-0.77,-0.17,-0.71,-0.82,-0.33,-0.73,-0.61.The correlation coefficients between WHO-DASⅡ total and six dimensional scores and the grade of sports classification were:-0.741,-0.378,-0.806,(-0.541),-0.293,-0.510,-0.677.ConclusionWHO-DASⅡ can be used in assessing the function of disabled athletes.

Objective To know the etiology distribution and drug resistance in neonate, hope to provide the reference for clinic.Methods The identification and susceptibility of bacteria were detected by culture.Results 583 bacterial strains were identified from total 560 positive samples from 2127 neonate (25.8%).The infection neonates of single bacterial and complex bacterial were 537 and 23 respectively of all 560 patients.The ratio of staphylococcus aureus, klebsiella pneumoniae and E.coli were 29.5%,22.0% and 17.0% respectively in total 560 patients.Staphylococcus Aureus of Resistance to Vancomycin(VRSA) wasn't be found.Conclusion Respiratory tract infection is the major cause of infection in newborn, including staphylococcus aureus, klebsiella pneumoniae and E.coli.
