OBJECTIVETo study the relationship between pharmacological effects and properties of traditional Chinese medicine by the decision tree algorithm.

METHODBased on of pharmacological effects of traditional Chinese medicine, the decision tree algorithm was applied in the study on the relationship between pharmacological effects and properties of traditional Chinese medicines. A model was established with the decision tree algorithm for the purpose of predicting the properties of traditional Chinese medicine components.

RESULTThe established model was reliable and stable, and could be used to predict the properties of traditional Chinese medicine components.

CONCLUSIONThe prediction for the properties of traditional Chinese medicine components with a decision tree model could reflect the theoretical connotation of the properties of traditional Chinese medicine components to some extent and provide a new method for studying the properties of traditional Chinese medicine components.

Objective To prospectively evaluate 3D time-of-flight magnetic resonance angiography (3DTOF MRA) and high resolution contrast enhanced volume scan magnetic resonance angiography (CEMRA) with sensitivity encoding in diagnosing craniocervical artery stenosis. Methods Forty-six patients suspected with craniocervical artery diseases underwent MRI, 3DTOF MRA of the head and also CEMRA of the neck. The images of MRA were reconstructed with MIP and VR. The degree of arterial stenosis demonstrated on MRA was compared with that showed on digital subtraction angiography(DSA), and the data were analyzed with Spearman rank correlation coefficient (Rs). Results Excellent correlation in determining the degree of craniocervical artery stenosis existed between MRA and DSA (Rs = 0.97). With DSA as a golden standard, the sensitivity, specificity and accuracy of MRA in detecting over 50% arterial stenosis were 100%, 99.4% and 99.4% respectively. Conclusion 3DTOF MRA and CEMRA with sensitivity encoding at 3.0T are reliable and effective examinations for evaluating craniocervical artery disease. These techniques can be used as the necessary exams before DSA and can even substitute for the conventional DSA in some instances.

Abstract: In order to investigate immune protection against swine-origin influenza virus (S-OIV) A H1N1, the helper-dependent adenovirus vector (HDAd) system was exploited to construct recombinant HDAd encoding hemagglutinin (HA). The HA gene was synthesized and cloned to the HDAd backbone. Then, the HDAd/HA DNA molecules were transfected into 293Cre4 cells with calcium phosphate. The cells were infected by helper virus 16 hours after the transfection. The 293Cre4 cells were coinfected with HDAd/HA and the helper virus for large-scale preparation of HDAd/HA. The HDAd/HA was obtained and purified twice with CsCI density ultracentrifugation and observed morphologically under transmission electron microscope, and the expression of HA protein was analyzed with RTPCR. Recombinant HDAd/HA expressing HA protein was successfully constructed which could pave the way for in vivo investigation on immunogenicity and efficacy against S-OIV A H1N1 infection.

Objective To observe insulin resistance (IR) in non-diabetic peritoneal dialysis (PD) patients,and analyze its related factors.Methods The non-diabetic PD patients who had been on stable PD at least three months were eligible to enroll.The patients were measured for their height,weight,waist to hip ratio,fasting glucose,fasting insulin,lipids and other biochemical indicators,dialysis adequacy indicators in August 2012,and divided into two groups depended on median HOMA-IR in August 2012.Results A total of 56 patients were enrolled and divided into two groups according to median HOMA-IR,including high IR group (HOMA-IR≥ 1.79,n=29) and low IR group (HOMA-IR ＜ 1.79,n=27).Compared to low IR group,high IR group were older [(57.9±14.2) years vs (48.7±14.5) years],had higher daily dialysate glucose load [(138.7±28.5) mmol/L vs (114.0± 21.5) mmol/L],higher waist-to-hip ratio [(0.91±0.08) vs (0.86±0.07)],higher BMI [(23.0±3.0) kg/m2 vs (21.2±3.1) kg/m2],higher triglycerides [(2.51±1.36) mmol/L vs (1.42±0.48) mmol/L],lower high-density lipoprotein cholesterol [(1.00±0.27) mmol/L vs (1.23±0.32) mmol/L],and lower Kt/V [(1.74±0.37) vs (2.08±0.56)].Multivariate logistic regression showed that age (β=0.122,P=0.033),triglycerides (β=1.798,P=0.030) and daily dialysate glucose load (β=0.094,P=0.031) associated with the degree of insulin resistance.Conclusion More dialysate glucose exposure is a risk factor of the occurrence of insulin resistance in non-diabetic patients with peritoneal dialysis.

Objective To investigate the characteristics of common causes of acute pancreatitis (AP) in China and to evaluate the association of the aetiology with the severity of disease.Methods The relevant literature was searched from the China National Knowledge Infrastructure (CNKI) database (1989.1-2015.3),WANFANG database (1999.1-2015.3),VIP database (1994.1-2015.3),and China Academic Journal Network Publishing Database (CAJD).To collect related literature about aetiology and the severity of acute pancreatitis,Meta analysis was performed for gallstone,alcohol,hyperlipidemia and other AP from the aspects of the severity of disease in the literature which reaches the criteria.Results The Meta analysis included 24 clinical articles which were accordance with the criteria,totally 17359 patients,including 8673 cases of biliary AP [6690 cases of mild acute pancreatitis (MAP),1983 cases of acute necrotizing pancreatitis (ANP)],1408 cases of alcoholic AP (1022 cases of MAP,386 cases of ANP),1753 cases of hyperlipidemia AP (1107 cases of MAP,646 cases of ANP),and 5525 cases of other aetiology (4179 cases of MAP,1346 cases of ANP).The Meta analysis showed that among the common causes which was developed to AP,there was significant difference between biliary AP and alcohol AP (OR =0.65,95％ CI:0.45 ～0.93,P ＜ 0.05).There was significant difference between biliary AP and hyperlipidemia AP (OR =0.51,95％ CI:0.33 ～0.79,P ＜0.05).However,there was no significant difference between alcoholic AP with hyperlipidemia AP (OR =0.70,OR =0.70,95％ CI:0.46 ～ 1.05,P ＞ 0.05).Conclusions There is difference in the severity of AP caused by different reasons in China.There is more likely that hyperlipidemia AP and alcohol AP easily developed into ANP than biliary AP.However,further investigation and large-scale clinical trials will be needed to confirm this conclusion.

Objective To determine the correlation between mouse maerophage metalloelastase (MME)and vascular endothelial growth factor(VEGF)expression involved in angiogenesis of colon cancer.Methods A eDNA fragment coding for domainsⅠandⅡof MME was transfected into murine CT-26 colon cancer cells that were MME deficient.The enzymatic activity of recombinant MME was confirmed by cleavage of native substrate in vitro.An orthotopic implantation model was established by using MME-transfected cells and control cells.Tumor samples were subjected to in situ hybridization (ISH)and immunohistochemical staining(IHC)to detect expressions of MME and VEGF.The microvessel counting was used to assess angiogenesis of murine colon tumors.Results It was demon- strated that the tumor growth was significantly inhibited in MME-transfected group compared with pcDNA3.1 transfected and nontransfected groups(P＜0.001).It was also found that,compared with pcDNA3.1-transfected and nontransfected groups,the microvessel formation in MME transfected group was significantly reduced(P＜0.001).The expression of VEGF mRNA and protein was significantly lower in MME-transfected group than those in the controls,as demonstrated by ISH(MME-transfected group versus pcDNAa.1-transfected group,P=0.028;and versus nontransfected group,P=0.003) and by IHC(MME-transfected group versus pcDNA3.1-transfected group,P=0.025;and versus non- transfected group,P=0.008).Conclusions The MME gene transfected into murine colon cancer cells can effectively suppress the growth of orthotopic tumors by inhibition of vaseularity.Both MME and VEGF gene expression is highly associated with the vascularity of tumors,which may depend on a hal- ance between MME and VEGF expression.
