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 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

Objective To study the expression of E-cadherin protein and Snail protein in the labial glands of patients with primary Sj(o)gren's syndrome(pSS) and to analyze their roles in the pathogenesis of pSS.Methods The expression of E-cadherin protein and Snail protein were detected by immunohistochemical method.The labial glands were obtained from 50 patients with pSS and 30 healthy controls.The data was analyzed by Chi-Square test,Fisher's exact probability and Spearman's rank correlation analysis.Results The expression rate of E-cadherin in the labials gland of the patients with pSS were lower than that in normal salivary tissues (x2=14.651,P＜0.01).The positive rates of Snail in the labial glands of the patients with PSS were 40％ and it's expression rates were significantly higher than those in normal salivary tissues (x2=28.800,P＜0.01).There was a negative correlation between lymphocyte focus score and the expression of E-cadherin (P＜0.01) and a positive correlation between lymphocyte focus score and the expression of Snail in pSS group (P＜0.01).There was a negative correlation between the expression of E-cadherin and Snail (rs=-0.484,P＜0.01).Conclusion The interaction of E-cadherin and Snail may have played an important role in the pathogenesis of PSS.

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.ResultsGroup 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

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 characteristics of P3a and P3b which are the subcomponents of P300 event-related potential in patients with vascular cognitive impairment (VCI) ,and to investigate the relations between P3a,P3b and the changes of cognitive function and cerebral blood flow. Methods Thirty patients with VCI and twenty two normal subjects were tested for P3a and P3b cognitive function ischemic focus and cerebral blood flow and then analyzed for correlation. Results (1) The latency of P3a ((446 ± 71) ms, (429 ± 67) ms, (446±61)ms,(428±66)ms)and P3b((496 ±73)ms,(478 ±75)ms,(498 ±77)ms,(483 ±77)ms) was significantly prolonged in patients with VCI compared with that in normal subjects in all recorded regions(P<0.01) . The amplitude of P3a in patients with VCI ((3.3 ±2.6)μV,(3.3 ± 1.8)μV) was significantly lower than that in normal subjects in Fz and Pz (P<0.01) ,and the amplitude of P3b in patients with VCI((4.5 ±2.5)μV,(6.4 ± 3.8)μV,(5.3 ±3.8)μV,(5. 3 ±3.0)μV) was significantly lower than that in normal subjects in all recorded regions (P < 0.01 or P<0.05) . (2) The latency of P3a and P3b in patients with VCI was negatively related to the scores of sub items of attention and MMSE total scores (P < 0.05 or P < 0.01), the amplitude of P3a was positively related to the scores of MMSE total scores(P<0.05) ,the amplitude of P3b was positively related to the scores of attention and MMSE total scores(P<0.05). (3) The latency of P3a in patients with VCI was positively related to frontal lobe(P<0.05) ,and the latency of P3b was positively related to parietal lobe(P<0.05). (4) The latency of P3a in patients with VCI was positively related to RILMCA,RILACA and RIRACA(P<0.05 orP<0.01) ,the latency of P3b was positively related to RILMCA,RIRMCA and RIRACA(P<0.05 orP<0.01) ,and the amplitude of P3a was positively related to RILACA(P<0.01). Conclusion P3a and P3b are good objective indexes for testing the descent of cognitive function in patients with VCI,which can provide reference basis for the clinical diagnosis.

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.
