The prevalence of obesity,type 2 diabetes,and other chronic non-communicable diseases is increasing rapidly world-wide.Most recent epidemiological data showed that China is now in an era of obesity,and under a huge burden of the complications related with obesity,diabetes,as well as cerebral-and cardiovascular disorders.Strenuous efforts,comprehensive strategies,effective measures,and practical solutions must all be taken to combat against these chronic diseases.

Objective To study the relationship between the aged retirees' group's body mass index(BMI)distribution characteristics and relative cardiovascular diseases risk tactors.Methods One thousand three hundred and forty-three retirees in health medical examination were tested for systolic pressure, diastolic pressure,serum triglyceride,total cholesterol and fasting blood glucose.Groups with different BMI and different genders were tested for their mortality.Results The detective rates of BMI insufficiency,normal,overweight and obesity were 6.18%,51.67%,35.52%and 6.63%respectively.There was no statistic significance between different genders.The prevalence rates of hypertension,hyperlipidemia and diabetes mellitus(DM)were 46.09%,46.91%and 7.45%respectively.It showed that the prevalence rates of male hypertension and hyperlipidemia were significantly above those of the female's(P<0.05).As the BMI increased,hypertention,hyperlipidemia and DM rates increased too,and obviously increased in overweight group compared to normal BMI group(P<0.05).The detective rate of cardiovascular disease increased correspondingly with the increase of BMI.Conclusion BMI increasing is the important vascular relative risk factor for the aged retriee.

The cardiovascular system is closely associated with sex hormones. The risk factors of the cadiovascular diseases or related events, such as lipid metabolism, coagulatory function and vascular endothelium function are affected by sex hormones and their analogues by a number of pathways. Consensus is generaly reached about hormone replacement therapy (HRT) among menopausal women except the effects on cardiovascular system, which removined to be controversial. It is recommended that women should consult their doctors for their individulized administration of HRT.

As the introduction of novel agents,the median overall survival of elderly newly diagnosed multiple myeloma patients has increased roughly from 30 to 60 months.But patients with high risk prognostic features still have a poor clinical outcome.This paper which combined the 19th annual congress of the European Hematology Association (EHA) reviews the advances in elderly patients with newly diagnosed multiple myeloma,including standard of care,the way to treatment and prognostic factors.

NKG2D is an activating receptor expressed on various immune cells' surfaces.Currently,eight ligands have been found,they can be divided into two kinds:MHC Ⅰ related protein and ULBP molecules.NKG2D receptors and their respective ligands differentially exist in normal and cancerous tissues.So far,many researchers have found that a lot of immune cells' anti-tumor mechanism is mediated by NKG2D receptor and it can't be replaced in the resistance to the development of carcinoma.adoptive immunotherapy is a new method of treating cancer that propose to find tumor-specific cytotoxicity immune cells and enlarge the amount of it,then injected into human body to resist tumor.Recently,many researchers have found that DNT cells (CD4-CD8-T 细胞)have the function of anti-tumor;sadly its mechanisms are unclear.After the summary of NKG2D receptor-mediated pathway of destruction,this paper try to analyze its relevance to DNT cells' killing effect,on the purpose of finding the Killing mechanism of DNT cells that may existed.

BACKGROUND:Rabbit VX2 hepatocarcinoma models are characterized by expanded and infiltrative growth, abundant blood supply, similar pathological and imaging features to human hepatocelular carcinoma, so this model is ideal for imaging experiments. OBJECTIVE: To establish rabbit VX2 hepatocarcinoma models and compare two different laparotomy methods in establishing rabbit VX2 hepatocarcinoma models. METHODS:Thirty New Zealand rabbits were randomly divided into two groups: traditional laparotomy (tumor particles were directly embedded into the liver with tweezers) and improved laparotomy (tumor particles were injected into the liver through a 15G syringe needle). The growth features of the tumor established in two different ways were compared by ultrasound. RESULTS AND CONCLUSION:The tumor formation rate was 100% in the two groups; the single rate was respectively 50% and 90%; the ectopic implantation rate was 50% and 10%, there were significant differences between two groups (P < 0.05). The mortality rate within 2 weeks was 33% and 0 in the two groups, with significant differences (P < 0.05). The improved laparotomy method is feasible for modeling rabbit VX2 hepatocarcinoma, due to minimal injury, short operation time, high success rate and stable features.

Objective: To observe the anti-hypertensive effect of pomegranate polyphenols in spontaneously hypertensive rats ( SHR) and explore the underlying mechanism. Methods:Totally 40 male SHR rats at the age of 12 weeks were randomly divided into five groups:SHR control group, pomegranate polyphenols groups respectively at the dose of 120 mg·kg-1 , 240 mg·kg-1 and 480 mg ·kg-1 , and captopril group at the dose of 15 mg·kg-1 . The age-matched Wistar-Kyoto ( WKY) rats were randomly divided into two groups:WKY control group and pomegranate polyphenols group at the dose of 480 mg·kg-1 . All the rats were given corresponding drug or water by intragastric administration for four weeks. The systolic blood pressure ( SBP) and diastolic blood pressure ( DBP) were measured weekly. After the 4-week administration, the rats were fasted 12 hours and anaesthetized with 25% urethane solution. The blood samples were collected from abdominal aorta. The serum concentrations of angiotensin II ( Ang II) and endothelin ( ET) were de-termined by euzymelinked immunosorbent assay. The concentration of nitric oxide ( NO) in serum was determined by nitrate reduction test. Results:Pomegranate polyphenols could significantly lower the SBP and DBP, decrease the serum concentrations of Ang II and ET, and increase the serum concentration of NO(P<0.05 or P<0.01). In addition, pomegranate polyphenols had no effects on blood pressure and vasoactive substances in WKY rats. Conclusion: Pomegranate polyphenols has anti-hypertensive effect in SHR rats. The mechanism may be related to regulating the expression of vasoactive substances, such as Ang II, ET and NO.

It is general belied that myocardial ischemia caused an increase of plasma fibrinogen(Fg),but the changes of Fg in ischemic region is not clear.In 17 open chest dogs, an external stenosis or infarction was produced by a micro-meter constrictor on left circumflex coronary artery. The changes of Fg and platelet count(PC) in coronary sinus were observed for 60 min. The results showed that acute myocardial ischemia produed a decrease in Fg when coronary artery stenosis was more than 75%; there was also a decrease in PC when stenosis was more than 90%. The reduced amplitude of PC was more than that of Fg. Histopathologic examination confirmed the presence of damanged endothelial cell, platelet adhesion and aggregation coronary thrombosis and microemboli in ischemic region It is suggested that acute myocardial ischemia lead to a decrease of Fg in the ischemic myocardium, which was associated with platelet aggregation and coronary thrombosis.

Human peripheral blood lymphocytes and sheep red blood cells(SRBC)were incubated together in Hanks solution containing Ca~(2+) and Mg~(2+) ion, causing SRBC destruction and release of hemoglobin, 500%hemolysis value was found to 6.1921?0.06. The destruction of SRBC by lymphocytes was inhibited by trypsinase, its 50% hemolysis value became 0.0348?0.03 (P
