Objective To select optimum water extraction process of SuXingErChen Syrup by orthogonal test and multivariate nonlinear regression analysis.Methods Naringin was extracted by water, Used the naringin content and extraction rate of extractum as indexes.Based on the orthogonal test and multivariate nonlinear regression analysis to make sure the best way for extracting naringin from SuXingErChen Syrup.Results The optimal conditions of water extraction process was that the herbs were added seven times the amount of water without infiltration,extracted two times with 80 min each time,which was selected by multivariate nonlinear regression analysis.Conclusion The process of water extraction for the preferred Su XingErChen Syrup is exact, high effective and suitable for production needs.

Computer technology is one of the greatest achievements of the 20th Century. Its appearance not only brings a breakthrough development in various fields, but also brings promotion to the development of traditional Chinese medicine (TCM). TCM is a traditional medicine, and the modernization of TCM is urgent. Whether in the medical management or scientific research, the application of computer technology has penetrated into all levels. The following article described the contribution made by computer technology, pointed out possible problems and provided relevant thinking based on the application of TCM related systems and data mining technology.

Objective To investigate the biochemical differences between the cartilage of the residual ear of microtia patient and normal person. Methods Seven cartilage specimens from 7 about 10-years-old microtia patient's residual ears and 7 normal ears from cadaver of the same age were measured by electrophoretic mobility shift assay and spectrophotometer for collagen glycoaminoglycan (GAG), chondroitin sulfate (Chs), hyaluronan (HA) and keratin sulfate (KS) .Results Biochemical analysis showed that no significant difference were found in the collagen contents of the two groups. The microtia cartilage had more GAG (49.00?25.60) ?g/mg than that of the normal (28.25?4.80) ?g/mg. The composition of GAG were different between two groups: microtia group (HA 38.96+4.97 %, Chs 29.02 %?4.12 %, KS 32.16 %?7.41) % and normal group (HA 32.94 %?3.24 %, Chs 33.10 %?2.61%, KS 33.96 %?1.66 %). There were differences in HA and Chs relative contents, but not in KS between the two groups. Conclusions There is no difference in the collagen content between normal and microtia ear cartilage. But the latter has more GAG than the former. As for the constitution of GAG, microtia cartilage has a higher percentage of HA, lower percentage of Chs, and no significant difference in KS.

Since the definition of sepsis has been first proposed in 1991, the main content of the definition has been developed by infection + systemic inflammatory response syndrome as infection + organ dysfunction,and organ dysfunction is indicated by an increase in sequential organ failure assessment(SOFA) score.These are components of Sepsis-3 which was published in 2016.In Sepsis-3,the SOFA score in the identification and diagnosis of sepsis plays an important role,but Sepsis-3 was mainly used in adults,how to adjust it to children,some questions and details were proposed in this article.

Many researches have focused on the wnt-frizzled cascade in the recent years, while much work has been done in neoplastic diseases and embryology, the role of the wnt-frizzled signal transduction pathway in cardiovascular diseases has only recently begun to be explored. It plays a very important role in many physiological and pathophysiological processes, such as its transduction pathway, the healing after myocardial infarction, the proliferation, differentiation and orientation of cardiomyocytes, angiogenesis/neovascularization, cardiac hypertrophy and heart failure, the deposition of the extracellular matrix and so on. This article is aimed at its relation with myocardial infarction and the role of this pathway in cardiovascular diseases.[

OBJECTIVE:To analyze bacteria distribution and drug resistance of pediatric severe sepsis in our hospital,and to provide reference for clinical rational use of antimicrobial agents. METHODS:57 pediatric severe sepsis patients were collected from pediatric intensive care unit of our hospital during Jan. 2014 to May 2015. The results of pathogen culture and drug sensitivity tests were analyzed retrospectively. RESULTS:Of 57 children,pathogen were detected in 18 cases(31.58%). A total of 91 pathogen were detected,of which there were 24 strains of Gram-positive(G+)bacteria(26.37%)mainly including Staphylococcus and Entero-coccus,60 strains of Gram-negative (G-) bacteria (65.93%) mainly including Klebsiella pneumoniae and Acinetobacter calco-acetcus-A. baumannii complex and 7 strains of fungus (7.69%) as Candida. 4 strains of methicillin-resistant Staphylococcus,22 strains of carbapenems-resistant K. pneumoniae,21 strains of multi-drug resistant K. pneumoniae and 7 strains of multi-drug resistant A. calcoacetcus-A. baumannii complex were all detected. Methicillin-resistant Staphylococcus,Staphylococcus aureus and Streptococ-cus pneumoniae were sensitive to vancomycin and linezolid,with resistant rate of 0. K. pneumoniae was completely resistant to ampi-cillin sodium and sulbactam sodium,piperacillin sodium and tazobactam sodium,imipenem and cephalosporin,with resistant rate of 100%. Resistant rate of A. calcoacetcus-A. baumannii complex to major common antimicrobial agents was higher than 50%. Esche-richia coli was resistant to cefotaxime,and resistant rates of other antimicrobial agents were lower than 40%. CONCLUSIONS:Main pathogen of pediatric severe sepsis is G- bacteria in our hospital,and carbapenems-resistant K. pneumoniae is detected,to which should be pay attention. The multiple drug-resistant treatment should be adopted for pediatric severe sepsis caused by multiple drug-re-sistant bacteria. Antimicrobial agents should be selected rationally according to pathogen type and the results of drug sensitivity test.
