Alzheimer's disease(AD),the most common form of dementia,it is lack of effective cure or preventive treatment.Dementias in the elder are an increasing medical,social and economic problems and current treatments are only mildly effective.Recently,amyloid-beta protein(A?) has become a major therapeutic target.A? vaccine treatment can improve cognition in the patients with AD,but adverse events,such as meningencephalitis were observed in clinical study.The passive A? immunotherapy in humans is effective with possible safety.However,patients need to be monitored carefully.

Doctor's degree is the highest degree for medical education.Nowadays,medical doctor candidates in more and more medical universities are requested to publish research papers in intemational journals embodied in Science Citation Index(SCI),or they can not graduate with doctor's degree.So,it is significant for medical doctor candidates to learn the related knowledge about SCI and Impact Factor(IF).

Insulin resistance model of 3T3-L1 adipocytes were prepared with plamotic acid.Adipocytes with generated insulin resistance were cultured with different concentrations of globular domain of adiponectin(gAd:250,500,1 000 ng/ml).The cell culture medium glucose content was detected with the glucose oxidase method,the mRNA expressions of insulin receptor substrate-1 (IRS-1),phosphatidylinositol-3 kinase(PI3K),and protein kinase B(PKB) were detected with real-time quantitative PCR method.The phosphorylation of IRS-1 was detected by Western blot.Compared with the control group,the experimental group showed significantly increased glucose consumption (P ＜ 0.01),and with the increasing gAd concentration,glucose consumption was gradually increasing.IRS-1 phosphorylation was increased gradually with the increasing concentration of gAd.These results suggest that gAd can promote glucose uptake by 3T3-L1 adipocyte model with generated insulin resistance.This may be correlated with promoting insulin signal transduction and improving insulin resistance in adipocytes.

Objective To explore the effect of minimally invasive clinical pathway in patients after car-diac interventional therapy. Methods One hundred and twenty patients who received cardiac interventional therapy from June 2005 to October 2006 were divided into the control group and the observation group.The control group received routine nursing while the observation group adopted minimally invasive clinical pathway of nursing.The nursing effect in the two groups was compared. Results The mean hospitalized duration, sat-isfaction degree and health knowledge level in the observation group were superior to those of the control group (P ＜ 0.05). Conclusions The adoption of minimally invasive clinical pathway in patients after cardiac inter-ventional therapy could increase working efficiency nd ensure the nusing quality.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.

OBJECTIVE To survey the antibiotic susceptibility of Pseudomonas aeruginosa and medical treatment among the aged patients suffering from underlying disease.METHODS A total of 326 strains of P.aeruginosa were isolated among the aged patients with underlying disease by sputum culture.Drug susceptibility was performed and effective antibiotic treatment was given.RESULTS Amikacin(8.0%),imipenem(12.0%) and piperacillin/tazobactam(16.0%) could be chosen.The symptom of 326 patients was alleviated after clinical treatment,while some sputum samples were found still positive.CONCLUSIONS Combined use of two kinds of medicines may produce better effects in the patients with underlying disease,who infected with P.aeruginosa,but sputum should not be emphasized to converse negative in this case.
