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.

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 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.

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.

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 effects of c-myc promoter binding protein(MBP-1)gene expression silencing on the pro-liferation in vitro in human gastric cancer cell line SGC-7901.Methods The cells divided into three groups:blank control group (cells without transfecting gastric cancer cell),negative control group(cells transfecting missense sequence)and experimental group (cells transfecting MBP-1 shRNA).Two MBP-1 shRNA sequences and one negative control shRNA sequence were designed,syn-thesized and cloned into pSIREN-retroQ plasma.Then the recombinant plasmids were constructed and transfected into human gas-tric cancer SGC-7901 cells by Lipofectamine 2000.After selection of cells with puromycin for two weeks,stable cell line SGC-7901 expressing gene of MBP-1 specific shRNA was obtained.The expressions of MBP-1 mRNA and protein in SGC-7901 were deter-mined by the real time PCR and Western blot,respectively.The effects of altered expression of MBP-1 on the cell proliferation were measured by MTT cell proliferation assay.Results PCR and sequencing indicated that the recombinant plasmids pSIREN-retroQ was constructed.Then the recombinant plasmids were transfected into human gastric cancer SGC-7901 cells by Lipofectamine 2000. After selection of cells with puromycin for two weeks,stable cell line SGC-7901 expressing gene of MBP-1 specific shRNA was ob-tained.The relative expression level MBP-1 mRNA in the MBP-1 siRNA transfection group was significantly decreased compared with the blank control group(P <0.05).Compared with the blank group,the expression levels of MBP-1 protein in the experimental group also significantly decreased.The proliferation abilities of SGC-7901 cells at 48,72,96,120 h after MBP-1 siRNA transfection were significantly increased compared with the blank control group (P < 0.05 ).Conclusion Down-regulating the expression of MBP-1 can obviously promote the proliferation of human gastric cancer cell line SGC-7901.MBP-1 gene may become the new target of gene therapy for gastric cancer.

The conformity between bone implant and bone tissue plays an important role in osseointegration.Protein molecules such as extracellular matrix proteins,cytoskeletal proteins,and attachment proteins,which produced by osteoblasts,promote the attachment of osteoblasts to bone implant and the surrounding ceils.In vitro studies show that nano-plated implant material bears excellent biocompatibility and superior physical and chemical features.Nano-scale material has the advantage of high surface roughness,wettability and electrochemistry features which erdaance the adherence and interaction of extracellular matrix proteins and promotes the attachmerit,proliferation and differentiation of osteoblasts.The expression of cytokines,such as prostaglandin E2(PGE2)and transforming growth factor-β(TGF-β)are also increased in nano-structured bone implants which in turn promote the new bone formation.Further studies need to be done to explain the mechanism of the effect of nano-tructured bone implant on osteoblasts.
