mia and hypertension are the major risk factors for occurrence of diabetic retinopathy.High UA may be also associated with occurrence of diabetic retinopathy.

Objective An intensive analysis on the recent advances in cardiovascular medicine both in China and abroad was made,so as to provide an orientation of developing cardiovascular medicine in the future.Methods Literature of cardiovascular medicine published domestically and abroad in recent 5 years was reviewed.The advances in the use of new drug and techniques,clinical diagnosis and therapeutic methods were analyzed.Results Cardiovascular medicine in basic,clinical and practical fields had made rapid advances in the military institutions lately,especially in the interventional diagnosis and treatment of coronary heart disease,arrhythmia and peripheral vascular disease,and in the treatment of hypertension,where outstanding successes had been achieved.Conclusions The general level of cardiovascular medicine of military medical establishments could be considered foremost in our country.During the coming years of "the 12th Five-Year Plan",the emphasis of research work should be placed upon the medical care,basic and clinical research of common cardiovascular diseases existing in military officers and soldiers,such as coronary heart disease,peripheral vascular disease and arrhythmias,both in peace time and military conflicts.

Objective To study the effect of rising [Ca 2+ ]i on the expression of Caspase 3, Bax and Bcl 2 in human breast cancer MCF 7 cell lines. Methods After the MCF 7 cells treated with different dose of thapsigargin(TG), intracellular calcium concentrations in MCF 7 cells were measured by calcium sensitive fluorescence indicator Fura 2/AM technique; and immunohistochemical method was used to detected the expressions of Caspase 3, Bax and Bcl 2. Results Bax was over expressed and Bcl 2 was down expressed in a [Ca 2+ ]i concentration dependent way;nevertheless, the expression of Caspase 3 was negative in all the TG treated cells. Conclusions The increase of intracellular calcium concentration may have an inductive effect of apoptosis on MCF 7 cells, which is independent to Caspase 3.

Objective To study the apoptotic induction effect of Thapsigargin on estrogen receptor positive human breast cancer cell lines MCF 7. Methods Cells were treated with Thapsigargin and 5 FU in vitro . The rate of cell apoptosis and distribution of cell cycle were detected on flow cytometry. The cell viability was measured by MTT assay and ultrastructural changes in apoptotic cells were confirmed by transmission electron microscopy.Results Thapsigargin could increase the rates both of cell apoptosis and growth supression of MCF 7 cells induced by 5 FU and alter the distribution of cell cycle. Under electron microscope, apoptotic bodies in MCF 7 cells considerably increased.Conclusion Thapsigargin apparently enhances the effect of apoptotic induction of 5 FU on MCF 7 cells, it is worthy of being further studied.

The freshmen column in 39 985 Projectacademic libraries was investigated , which showed that 15 out of the 39 985 Projectacademic libraries have established freshmen column on their library website .Its posi-tion, contents and forms were analyzed.The typical freshmen column in libraries of Qinghua University, Shanghai Jiaotong University , and Sun Yat-sen University was described with suggestions put forward for improvement of its position, contents and forms.

Objective To observe the effect of irbesartan in treating patients with congestive heart failure.Method Forty_two patients\[male26,female16,average age (61?11) with heart failure \[cardiac function (NYHA) grade Ⅲ15 patients,grade Ⅳ27 patients\], who had unsatisfactory results under conventional digitals,diuretics, vasodilators therapy ,were given irbesartan (angiotensinⅡreceptor antagonist)75～300mg orally once a day for 4～6 weeks. The changes of heart rate (HR),blood pressure(BP),cardiothoracic ratio ,left ventricular end diastolic diameter (LVEDD),left ventricular ejection fraction (LVEF) and cardiac function (NYHA) were observed.Results After 4～6 weeks therapy,HR,BP,cardiothoracic ratio and LVEDD all decreased significantly(P

Objective To study the pulmonary function changes in patients cured from severe acute respiratory syndrome(SARS) Methods Pulmonary function tests were performed in 11 SARS patients one month after their discharge from hospital Results The subjects (3 males and 9 females) were aged from 21 to 62 years (31 0?10 0) The days after their discharge from hospital were 22 to 43 days (32 2?4 7) Pulmonary function showed:vital capacity(VC) (95 6?19 0)% predicted,forced vital capacity(FVC) (97 2?9 9)% predicted,forced expiratory volume in one second(FEV 1)(97 5?9 8)% predicted,FEV 1/FVC (85 9?5 6)%,total lung capacity(TLC) (102 4?10 4)% predicted,residual volume(RV)/TLC (32 6?5 0)%,RV (116 8?25 0)% predicted,and diffusing capacity of CO(DLCO) (73 6?10 9)% predicted Conclusion The patients cured from SARS demonstrated relatively normal ventilatory function but mild impaired diffusing capacity

Objective To investigate the recent studies on the biocharacters of keratin family (e.g. genetic mutations and abnormal expressions) and their relationships with the malignant tumors. Methods The literatures of recent years on the biocharacters of keratin family (e.g. genetic mutations and abnormal expressions) and their relationships with the malignant tumors were reviewed. Results Keratin family is a kind of structural proteins in cell which plays an important role in cytomechanics and regulates cell-cycle. The mutations of keratin genes (mRNA) or the overexpression of keratin proteins would interfere with the order of cell-cycle or the integrity of cytomechanics, and lead to some diseases and malignant tumors finally. Conclusion The studies on biocharaters of keratin family (e.g. genetic mutations and abnormal expressions) are helpful in the diagnosis, staging and the evaluation of prognosis of some diseases and cancers, e.g. liver cirrhosis, breast cancer, rectum carcinoma, etc.

Objective To study the mental hea lth of drug addicts and its correlation with addictive behavior. Method s 143 drug addicts in treatment were investigated and analyzed with The Symptom Checklist 90 and Addictive Behavior Questionnaire. Results The mental health of drug addicts was worse than that of normal peo ple, and somatization, depression, anxiety and psychopathy in the factor of SCL -90 had high proportion in high score field. Sex, having occupation or not, and living alone had no significant differences in SCL-90 score. The results of co rrelation analysis of mental health and addictive behavior were that the quantit y and frequency of drug use had positive correlation with mental health. The con trol power of drug use desire had negative correlation with mental health. Conclusion The mental health of drug addicts is worse, and addi ctive behavior is correlated with mental health.
