Cardiovascular disease has become the first cause of human death.Among the many risk factors in coronary heart disease,depression has been identified as an independent prognostic risk factors.In patients with coronary heart disease accompanied by severe depression,the onset of angina,quality of life deterioration and the mortality will increase by 3～5 times.However,the majority of antidepressant drugs have adverse effects on cardiovascular disease adverse drug reactions,making coronary heart disease patients with depression,did not receive antidepressant treatment due.So more researches to clarify the anti-depressant drugs,safety for cardiovascular disease are needed.

OBJECTIVE: To investigate the tagging condition in medication of special population in package inserts in order to give reference for rational drug use of special population. METHODS: 389 pieces of common Chinese and western medicine package inserts of our inpatient and out-patient dispensaries were randomly collected and analyzed statistically in terms of the content of package inserts for special population, including pregnant and lactant women, children and the aged. RESULTS: A part of medication items of special population in package inserts had deficiency. According to the classification of dosage form, the tagging rate of injection exceeded other dosage forms reached to more than 90%, except of medication items for children. The tagging rate of oral formulation arrived at more than 90% only in terms of contraindications and cautions. According to the classification of manufacturer, the tagging rate of domestic drugs was kept at the low level while that of imported drugs exceeded 90%. CONCLUSIONS: Package inserts need to be improved with the effort of drug supervision management department, drug production department and population of using drugs to guarantee the safety of drug use in special population.

Objective: To discuss the risk factors of suicide with psychological autopsy method. Methods: 66 complete suicides from Jinzhou and Zhuanghe of Dalian , LiaoNing province, which were individually matched with control population. Results: Three main risk factors of suicide remained in the final conditional logistic regression model. They were social support (OR = 0.66, 95%CI = 0.48 - 0.91 ), depression (OR=1.18, 95%CI=1.03-1.35) and neurosis (OR=2594.59,95%CI=6.29-1069550) . Conclusion: The combined effect of multiple factors increases the risk of suicide but not the unique effect of single factor. The suicide preventive efforts should focus on individuals exposed to multiple risk factors.

Objective To know the effect of cold stress on the artery pressure and the concentration of IL-2, IL-10, IFN-?, TNF-? in the serum of the rabbits. Methods The local white rabbits of China (clean grade) were anesthetized. The mAP (mean artery pressure), mSP (mean systolic pressure), mDP (mean diastolic pressure) and the concentration of IL-2, IL-10, IFN-?, TNF-? were determined at 0 h, 0.25 h, 0.50 h, 0.75 h, 1.00 h, 1.50 h, 2.00 h, 3.00 h, 4.00 h and 6.00 h after cold stress. Results The mAP,mSP and mDP changed undulant with the delay of cold stress,but the whole tendency was descendent. The mAP,mSP and mDP went up to the peak at 1 h,however lower than control. The concentration of IL-2 increased then decreased with the delay of cold stress,the concentration of IL-10 went down then up and the concentration of TNF-?,IFN-? went down gradually. There was a strong correlation between IFN-? and TNF-? (r=0.983 0,P

Neural stem cells which have many characters of high self-renewal, multipotentiality, migration and good histocompatibility could differentiate neurons, astrocyte and oligodendrocyte. Therefore, the research on differentiation mechanisms of neural stem cells should be very important for the therapy of nervous system degenerative diseases and functional recovery of the central nervous system injury. The neural stem cells differentiation mechanisms regulated by the genes and environment were reviewed in the present paper.

OBJECTIVE:To provide reference for the practice of monitoring on adverse drug reactions (ADRs) in secondary or inferior to secondary medical institutions.METHODS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions were analyzed and the approaches to strengthen the ADR monitoring was discussed taking our hospital as an example.RESULTS & CONCLUSIONS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions manifested as low general technical level,lacking of advanced information network,hospital leaders' negligence,medical staff's poor consciousness,pharmacy departments' failure in bringing their role into full play,etc.Therefore,it is urgent to attach great importance to the problems to facilitate the development of ADR monitoring by enlarging publicizing,raising awareness;improving the organizational structure and the related working rules,bringing clinical pharmacists and nursing staff's roles into full play and establishing the reward and punishment mechanism,etc.

Objective\ To explore the risk factors of dementia induced by stroke.Methods\ 258 elder patients with stroke had been followed up for three months,including clinical neuropathy and neuropsychological tests.Multivariate noncondition stepwise Logistic model analysis was made after single variable analysis.Results\ There were 83 patients with dementia induced by stroke,175 patients without dementia after stroke.The morbidity was 32.2%.The following eight factors were associated with dementia i.e.,age,multiple lesions,left lesion,large area of cerebral hemorrhage or cerebral infarction,cerebral atrophy,hypertension,the history of stroke,and bilateral lesions.Conclusions\ Dementia induced by stroke is caused by multiple factors.It is closely correlated to numbers of cerebral lesions,the location of cerebral lesions and the size of brain tissue necrosis.The primary conditions of patients'cerebral function are also closely associated with the occurence of dementia.

Objective To measure the expressions of HSP10 and 60 in cutaneous squamous cell carcinoma (SCC), basal cell carcinoma (BCC) and solar keratosis (AK) tissue. Methods Lesion samples were resected from patients with SCC (n = 50), BCC (n = 50) and AK (n = 50), and control samples were obtained from the normal skin adjacent to the operation sites of 14 of the 50 patients with SCC, BCC and AK. Immunohistochemical Envision two step method was used to detect the expression of HSP60 and 10 in the tissue samples.Results The expression of HSP10 was significantly higher in BCC tissue samples (Z = 3.24, P ＜ 0.001 ), but not in AK (Z= 0.74, P＞ 0.05) or SCC (Z= 0.52, P＞ 0.05) tissue samples than in the normal control tissue samples. Statistical significance was observed in the expression of HSP10 between AK and SCC and between AK and BCC tissue samples (both P ＜ 0.05), but not between SCC and BCC tissue samples (P ＞ 0.05 ). Elevated expression of HSP60 was found in AK, BCC and SCC tissue samples compared with the control samples (Z =-2.90, -2.15, -2.78,P ＜ 0.01, 0.05 and 0.01, respectively). Furthermore, the expression of HSP60 in SCC tissue samples was higher than that in BCC tissue samples (P ＜ 0.05 ) but similar to that in AK tissue samples. Conclusions There is likely to be a correlation between the high expression of HSP60 and biological behavior of SCC, and between the elevated HSP60 and HSP10 expressions and BCC initiation and development.

Objective To quantitatively assess left ventricular systolic function in rabbits with dilated cardiomyopathy(DCM) by quantitative tissue velocity imaging (QTVI). Methods Thirty rabbits were divided into two groups: group A(adriamycin group) and group B(sodium chloride group). Group A( n = 20) were given adriamycin 2 mg/kg intravenously once a week for eight weeks (total dose, 16 mg/kg) to induce DCM model, group B were given with the same dose of sodium chloride injection solution. Two dimensional echocardiography and QTVI examination were performed in all rabbits before and three weeks after the administration,respectively. Peak systolic velocity(Vs), peak displacement(D) and other common parameters were analyzed. Results Common parameters assessed after administration in group B did not show significant changes. The QTVI curves of left ventricle myocardium were regular and the value of Vs and D decreased gradually from the basal segments to the apical segments after the administration. The diameters of atrium and ventricle of group A increased,while the ejection fraction and fractional shortening of left ventricle decreased significantly ( P <0. 05 or P < 0.01). The pattern of the curves still had the regularity. But Vs and D value decreased significantly ( P <0. 05 or P <0. 01). Pathology of myocardium samples of group A showed the cardiomyocyte changes like dilated cardiomyopathy, while samples of group B had no significant change. Conclusions QTVI can accurately evaluate regional systolic function of left ventricle in rabbits with dilated cardiomyopathy, therefore provides experimental foundation for clinical observation and treatment.
