Objective To study the expression of SARS-associated coronavirus nucleocapsid(N) gene in Pichia pastoris and to obtain recombinant N protein with good biological activity.Methods The gene encoding the full N protein of SARS-CoV was amplified by PCR and cloned into Pichia pastoris expression vector pPICZA.The recombinant expression plasmid pPICZA/N was transformed into X-33,KM71H and GS115. The positive insert transformants were screened,cultured and induced by methanol.The recombinant protein was further purified with Ni affinity chromatography.Antigen activity was detected with anti-N monoclonal antibody,polyclonal antibody and sera from SRAS patients.Results SDS-PAGE and immunological analysis demonstrated that only Pichia pastoris transformants KM71H/pPICZA/N and X-33/pPICZA/N expressed Mr 70 000 fusion protein with special antigenicity.Conclusion SARS-CoV N protein expression in Pichia pastoris has been achieved,establishing the basis for further study of biological and immunological function of N antigen.

Objective:To explore improving effect of Danqi soft capsule on hemorheology in patients with coronary heart disease (CHD) and its myocardial protection effect .Methods:A total of 84 CHD patients treated in our hos‐pital from Dec 2013 to Dec 2014 were enrolled .They were randomly divided into routine treatment group (n=42) and combined treatment group (n=42 ,received Danqi soft capsule therapy based on routine treatment group ) .He‐morheological indexes ,ECG and inflammatory factor levels [C reactive protein (CRP) ,tumor necrosis factor α(TNF‐α)] were measured and compared between two groups before and after treatment .Results:Compared with before treatment , above hemorheological indexes significantly reduced in both groups after treatment ( P< 0.05 all) ,compared with routine treatment group ,there were significant reductions in high shear whole blood viscosity [ (5.12 ± 0.73) mPa/s vs .(4.47 ± 0.86) mPa/s] ,low shear whole blood viscosity [ (7.36 ± 1.32) mPa/s vs .(6.21 ± 1.03) mPa/s] ,plasma viscosity [ (1.47 ± 0.31) mPa/s vs .(1.31 ± 0.25) mPa/s] ,erythrocyte aggregation index [ (3.53 ± 0.45) vs .(2.93 ± 0.26)] and fibrinogen level [ (2.95 ± 0.28) g/L vs .(2.08 ± 0.24) g/L] in combined treatment group , P< 0.05 all .Total effective rate on ECG in combined treatment group was significantly higher than that of routine treatment group (85.71% vs .57.14% ,P<0.05) .Compared with before treatment ,CRP and TNF‐αlevels significantly reduced in both groups after treatment ( P<0.05 all) ,compared with routine treatment group ,there were significant reductions in levels of CRP [ (6.52 ± 1.61) mg/L vs .(5.18 ± 1.25) mg/L] and TNF‐α [ (283.28 ± 18.28) pg/ml vs .(245.08 ± 12.24) pg/ml] in combined treatment group , P<0.05 all .Conclusion:Danqi soft capsule combined routine treatment can significantly improve hemorheology and reduce related inflamma‐tory factor levels ,possess myocardial protection effect in CHD patients ,which is worth extending .

Objective To explore the decision-making processing changes of patients with cerebral infarction in different regions.Methods The patients with cerebral infarction were divided into 21 cases of frontal lobe infarction,11 cases of temporal lobe infarction,19 cases of the medial temporal lobe infarction,25 cases of basal ganglia infarction;25 cases of the anterior infarction,51 cases of the posterior infarction,62 cases of depression,64 cases of anxiety ;and there were 125 cases in normal control group.All subjects completed the test of the six kinds of choice situational problems,and used MMSE to evaluate cognitive function,the Hamilton Depression and anxiety Scale Evaluation to evaluate emotion.Results All cerebral infarction patients (CI group) and normal control group in low-risk and no-risk of loss situation(choice scenario 2),high-risk and the no-risk of gain or loss situation(choice scenario 3 and 4),high-risk and low-risk of gain or loss situation(choice scenario 5 and 6) tended to choose conservative scheme,and the selection probability of conservative scheme were obviously higher than that of the normal group,and the differences were statistically significant (P ＜ 0.05).In choice scenario 3,the basal ganglia infarction group with frontal lobe infarction group,the medial temporal lobe infarction group comparison,the conservative income scheme selection probability increased significantly,all difference were statistically significant (P ＜ 0.01,P ＜ 0.05).In choice scenario 5 of the posterior infarction group,a higher probability of conservative income scheme was selected than the anterior infarction,and the difference was statistically significant (P ＜0.05).Accompanied with depression and anxiety,the basal ganglia infarction tended to select more conservative income program than the frontal lobe infarction group and the medial temporal lobe infarction group in choice scenario 3,and the program infarction group selected a higher probability comparative differences were statistically significant (P＜ 0.01,P＜ 0.05).The posterior infarction group selected a higher probability of conservative income scheme than the anterior infarction in choice scenario 5,and the difference was statistically significant (P ＜ 0.05).Conclusion Cerebral infarction in patients exist decision-making processing abnormally,and perform as income conservative and loss risk averse.Whether associated with depression,anxiety,the basal ganglia infarction and posterior cerebral infarction patients are inclined to income conservative.

The proto-oncogene, c-kit gene, widely expresses on the mast cell, melanoeyte, haemopoietic stem cell, intestinal cell of cajal and germoeyte. Recent researches have revealed the relationship between the e-kit gene and the carcinogenesis, proliferation, infiltration and metastasis of some malignant tumor. This article aimed to make a review of its biological function, lab and clinical research advancement in the digestive tract tumor.

To support the ongoing health reform in China,Chongqing municipal government made the decision in 2008 "Building Healthy Chongqing" ,and pinpointed for the first time regional development as a key goal.In line with this situation,the hospital proposed such hypothesis changes as from "disease hypothesis to "health hypothesis",from "illness oriented" to "capability oriented",and from "shaping development" to "adaptive development",as well as from one-sided efforts of medical staff to minimize casualty to joint efforts with patients to safeguard life and health.Focusing on these four strategic shifts,the hospital works in developing its "technical attraction,service capacity,innovation capacity,and emergency assurance capability,and management soft power",aiming at building a sustainable hospital in its development.

Methods200 diabetic patients were selected.Using face to face questionnaire survey forms filled in the questionnaire in order to collect the general situation of all subjects selected.The diameters of vessels were measured using a computer-assisted imaging program. ResultsIn type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different sex.In type 2 diabetes mellitus,as age increased,both the retinal arteriolar diameters and the retinal veular diameters declined.In type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different BMI.In type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.After storied in accordance with age,we can draw the sameConclusion . ConclusionIn type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.

Objective To study the influencing factors of retinal vessel caliber in type 2 diabetes mellitus and supply the elementary data for clinic. Methods Two hundred diabetic patients were involved in this study, and the vessel caliber was measured by fundus oculi color photo and computer-assisted imaging program. Biochemical indicator and blood pressure was examined and other document was achieved by questionaire. Results In type 2 diabetes mellitus, the retinal vein caliber had negative correlation with age and positive correlation with fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c) and the duration of diabetes mellitus(P < 0.01 ). The retinal arteriole caliber had negative correlation with age, blood pressure and the duration of diabetes mellitus (P < 0.01 or < 0.05 ). Conclusion The influencing factors of retinal vessel caliber in type 2 diabetes mellitus are age,FBG,HbA1c,blood pressure and the duration of diabetes mellitus.
