AIM:To investigate the role of Shengmai Powder (Radix Ginseng, Radix Ophiopogonis and Fructus schisandrae) (SMP) in treatmen of hemorrhagic shock in rabbits. METHODS: The concentrations of endothelin (ET), tumor necrosis factor (TNF), ? endorphin (? EP) and nitric oxide (NO), the activity of nitric oxide synthase (NOS) in plasma were respectively tested by different biochemical assays in hemorrhagic shock in rabbits. RESULTS: SMP could obviously decrease the ET,TNF,NO level and NOS activity ( P

Objective To study the tumor suppression of Chinese caterpillar fungus water decoction combined cisplatin on a tumor burdened mice .Methods The beforehand vaccinal HCT8 tumor burdened mice were randomly devided into 5 groups(n=10) ,then 3 groups of Chinese caterpillar fungus water decoction were given a tumor burdened mice stomach (2 .5 ,5 .0 ,10 g/kg) ,1 times a day ,12 d .1 group of mice were given saline .1 group were given cisplatin .Determination of different concentrations of cordyceps water decoction lavage ,then observe the changes of tumor‐burdened bone tumors in mice weight .Results For vaccination HCT8 tumor burdened bone tumors had an average weight of each dose group mice compared with saline group have significant difference(P<0 .01) ,while Chinese caterpillar fungus water decoction (2 .5 ,5 .0 g/kg) and cisplatin group mice tumor block is more significant difference(P< 0 .01) ,the tumors had the lighter weight .Conclusion Chinese caterpillar fungus water decoction has tumor suppression effect on tumor burdened mice .

Objective To systematically evaluate the association between protein C and Legg -Calve -Perthes disease.Methods A literature research was performed through PubMed,Embase,Cochrane library,Web of Science,Chinese Biomedical Literature Database(CBM),China National Knowledge Infrastructure(CNKI)and Wan-fang Database from inception to February 201 6 on the association between protein C and Legg -Calve -Perthes disease.According to the Newcastle -Ottawa Scale(NOS)criteria,the quality of studies was evaluated and data were extracted.Meta -analysis was performed with Stata 1 1 .0 software.Results A total of 1 4 articles were included.Twelve articles on protein C and Legg -Calve -Perthes disease in the study group and the control group were compared.The results of Meta -analysis showed that there was no significant difference in protein C levels between the study group and the control group[odds radio(OR)=1 .41 ,95% confidence interval(CI)(0.87,2.28),P =0.1 47];five articles on protein C and the white race of Legg -Calve -Perthes disease between the study group and the control group were com-pared,The results of Meta -analysis showed that there was no significant difference in protein C levels between the whiteskin patients′group and the control group[OR =0.61 2,95%CI(1 .83,7.29),P =0.61 2];three articles on pro-tein C and the yellow race of Legg -Calve -Perthes disease between the study group and the control group were com-pared,and the results of Meta -analysis showed that there was no significant difference in protein C levels between the yellow skin patients group and the control group[OR =0.59,95%CI(0.05,6.72),P =0.080].Conclusion There is no significant correlation between protein C and Legg -Calve -Perthes disease.

To investigate the neurotoxic effect of human immunodeficiency virus (HIV) gp120 on cultured dorsal root ganglion (DRG)neurons in vitro, dissociated and organotypic mouse embryo's DRG cell culture models were established. Both dissociated and organotypic DRG cultures were treated with HIV gp120 in different concentration (250 pmol/L and 1 nmol/L, respectively, 2 times/7 days). For dissociated DRG cultural cells, microtubule-associated protein 2 (MAP2) immunofluorescent labeling was processed for observing the changes of neuronal cell body and neurites. The change of the ultrastructure in the organotypic cultured DRG was observed by electron microscopy.The difference of the number and length of neurites between the control group and HIV gp120 treated groups were significant (P＜0.001),whereas there was no significant difference in the diameter of neurons between them (P＞0.05). The ultrastructural changes included the decrease or loss of cristae in mitochondria and accumulation of many high densed particles between the microtubules and the neurofilaments by using both the concentrations of HIV gp120 treatment. The present results indicate that HIV gp120 had a directly neurotoxic effect on the cultured DRG neurons, especially more sensitive to mitochondria.

Shepp-Logan head phantom is the classical model of simulation computing in Computerized Tomography. This paper proposes a new method--considering 3D Shepp-Logan head phantom as the basic reference model to carry on simulation experiment and algorithms performance evaluating in three-dimension medical image reconstruction field. The paper introduces the design and the implementation of 3D Shepp-Logan head phantom as well the computing of projection data at first, and then describes the simulation process of the three-dimension medical image. The numerical experiment gives the three-dimension medical image reconstruction simulations based on 3D Shepp- Logan head phantom. The result of this experiment indicates the accuracy of model computing and the feasibility of our this method.

To further improve the diagnosis and treatment level of integrated traditional Chinese and Western medicine for the prevention and treatment of postoperative gastrointestinal disorder, and to promote the standardization of clinical practice guidelines for postoperative gastrointestinal disorder. It was initiated by the Chinese Society of Integrative Anesthesiology, and the " Clinical practice guidelines for prevention and treatment of postoperative gastrointestinal disorder by integrated traditional Chinese and Western medicine: a protocol" was jointly formulated by the institutions such as Gansu Province Clinical Research Center of Integrative Anaesthesiology, Center of Anesthesiology and Pain Medicine of Gansu Provincial Hospital of Traditional Chinese Medicine, World Health Organization Collaborating Center for Guidelines Implementation and Knowledge Translation, GRADE China Center, Industry Technology Centre for Medical Guidelines of Gansu Province, and Evidence-based Medicine Center of Lanzhou University. The Guidelines Formulation Committee followed the principles, methods and procedures of evidence-based guidelines formulation, assembled a multidisciplinary team of experts, and provided an evidence-based clinical practice guidelines using the GRADE method. This protocol mainly expounds the purpose and method of guidelines formulation and the publication, promotion, implementation and update of guidelines.
