OBJECTIVE:To research the correlation between per capita disposable income,investment of pharmaceutical advertisement,people’s healthy level,pharmaceutical price and the demand of drugs in China METHODS:Based on the economical theory,the methods of the econometrics and the Eviews were adopted to establish the model of demand function RESULTS & CONCLUSION:Under the background of the non-full competition,the improvement of people’s living conditions can lead to the demand of drugs The changes of drug price have little influence on the demand of drugs

By generalizing the integrity crisis of college students,the article analyzes the causes of this phenomenon,and proposes a series of measures aiming at strengthening integrity education,establishing the favorable environment,completing the mechanism of rewards and punishments and building the credit system,in the hope of securing the deepening and full completion of good-faith education at college,both ideologically and systematically.

The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by failure of the original vessel to provide adequate flow. Angiogenesis growth factors induce angiogenesis to promote collateral circulation, been demonstrated in a number of different animal test and phase Ⅰ clinical experience to induce collateralization in the ischemic area and improve cardiac function. Although there are several unsolved questions, the pharmacologic use of angiogenesis growth factors will represent a viable therapeutic alternative for the patients with ischemic heart disease.

Objective To find the inpact(s) of Losartan on myocardial apoptosis in rats with heart failure. Methods Eight-week-old male SD rats were divided into control group (group C) , heart failure (group HF) and treatment group (group LS). Use of doxorubicin injection model, group LS at the same time in a row to the oral losartan, myocardial ultrastructure was examined by TEM. DNA-situ terminal labeling (TUNEL method) was used to detect myocardial apoptosis and myocardial BAX, BCL-2 protein expression was detected by immunohistochemistry. Results Group HF showed significant myocardial cell injury, and apoptotic bodies were found, serum CPK, CK-MB and LDH were increased. In LS group, myocardial apoptosis index was lower (P <0. 01) , myocardial cells BCL-2 expression, BAX expression reduced as compared with those in HF group. Conclusion Losartan can effectively inhibit the process of heart failure occurred in cardiomyocyte apoptosis, reverse myocardial damage and improve the prognosis of heart failure.

Lysyal oxidase (LOX),a cooper dependent monoamine oxidase,can stabilize the extracellular matrix and is closely related to the tumor cell differentiation,vicious transformation and invasiveness.LOX is secreted into extracellular,and it is resolved into a small fragment by sol protease,which is lysyal oxidase propeptide (LOX-PP).According to research,LOX-PP has its own structure and physiological functions,which can inhibit the growth of tumor cells.LOX-PP also plays a significant role in the generation and progression of tumor,which is likely to be a new therapeutic target.

Dorsal-ventral axis formation is one of the earliest and the most important steps of patterning formation during early embryogenesis.The molecular basis of dorsoventral axis formation reflects the fundamental issues of orchestrated cell proliferation and differentiation.Wildly speculated since the Renaissance,the effort of deciphering the mechanisms of dorsal-ventral axis formation has contributed significantly to our current understanding of disease pathogenesis.Here,we focused our discussion on the recent discovery of the convergence of dorsal and ventral signaling pathways during early embryogenesis and its implications in cancer biology and beyond.

Objective To investigate the serum levels of anti-BRAF antibody in patients with rheumatoid arthritis (RA) and its clinical significance.Methods Blood samples from 129 patients with RA,71 patients with other rheumatic diseases and 68 healthy controls were measured by enzyme-linked immunosorbent assays (ELISA).The serum levels of anti-BRAF antibody in patients with RA were divided into high,medium and low groups,each group had 43 cases.The clinical symptoms,immunological findings and related imaging data of all cases were recorded.We investigated the relationship between the serum levels of anti-BRAF antibody and the clinical symptoms,immunological findings and related imaging changes of the RA group.Chi-square test,Mann-Whitney U test,Spearman's correlation test were used for statistical analysis.Results ① The serum levels of anti-BRAF antibody were significantly higher in RA group [A:1.093 (0.150-3.210)] than in other rheumatic diseases group [A:0.278 (0.093-0.455)] and healthy controls [A:0.202 (0.121-0.443)] (Z=-11.223,P=0.021 ; Z=-7.839,P=0.008 7).The serum levels of anti-BRAF antibody was not significantly different between patients with other rheumatic diseases group and healthy controls (Z=-0.905,P=0.445).② The difference in positive rate of rheumatoid factor (RF) in different groups of anti-BRAF antibody levels was statistically significant (λx2=10.14,P=0.006),namely the positive rate was significantlyhigher in the low-level group (88％) than in the high-level group (58％) (x2=10.03,P=0.002).Thepositive rate of anti-cyclic citrullinated peptide antibody and anti-keratin antibody of the three groups was not significantly different (x2=0.721,P=0.697; x2=1.735,P=0.188).③ There was significant negative correlation between the levels of anti-BRAF antibody and the course of disease (r=-0.233,P=0.047),RF(r=-2.84,P=0.039),IgM (r=-0.234,P=0.038),and hemoglobin (r=-0.287,P=0.032).There was no significant correlation between the level of anti-BRAF antibody and the joint swelling index (r=-0.133,P=0.230),joint pain index (r=-0.173,P=0.100),other clinical and laboratory parameters.There was significantly negative correlation between the ESR and hemoglobin level.④ There was no significant difference of the level of anti-BRAF antibody between the normal group and patients with bone destruction in the RA group (Z=-0.642,P=0.521).⑤ There was no significant difference in the level of anti-BRAF antibody between the normal group and patients with interstitial pulmonary fibrosis group in the RA group (Z=-0.121,P=0.904).Conclusion The anti-BRAF antibody can be used for the diagnosis of RA as a new autoantibody,and it can also be used in the diagnosis of early or RF-negative RA.There is no correlation between the level of anti-BRAF antibody and bone destruction and interstitial pulmonary fibrosis.

Asymptomatic bacteriuria is common in diabetic patients. This article reviews several aspects of asymptomatic bacteriuria in diabetes mellitus, including prevalence, mechanisms, coexisting risk factors, bacteriology, treatment and prognosis.

The G protein-coupled receptor, GPR40, is a specific receptor for free fatty acids. Singnaling pathways are activated in islet ?-cells by fatty acids as binding to GPR40. Fatty acids regulate insulin secretion and cause ?-cell hyperplasia through GPR40. GPR40 also mediates responses to antidiabetic drugs like thiazolidinediones. GPR40 agonists and/or antagonists show potential effect in the development of new anti-diabetic drugs.
