24) among male adults increased by years:9.4% in 1989,28.6% in 2000,and 34.1% in 2004。In 1989 the prevalence of hypertension was only 7.8% in men and 4.8% in women,while it reached 26.5% and 20.1% respectively in 2004. Conclusion:In the period of dietary transition,people in Jiangsu experienced the inadequate intake of some nutrients and high intake of fat. Overweight,obesity and hypertension are prevalent as results of this transition,so implementation of nutrition intervention is needed.

Objective To explore the effect of dexmedetomidine on blood coagulation following radical gastrectomy.Methods ASA Ⅰ or Ⅱ patients aged 51-70 years weighing 53-75 kg scheduled for radical gastrectomy were randomly allocated to two groups:dexmedetomidine group (group D)and control group (group C).Dexmedetomidine 0.5 μg/kg was intravenously infused over 10 minutes before anesthesia induction,followed by a rate of 0.5 μg·kg-1 ·h-1 until peritoneal closure in group D and volume-matched normal saline was administrated in group C.Radical gastrectomy was performed under total intravenous anesthesia with propofol and remffentanil.A series of warming measures were implemented and artificial colloid and heparin flushing fluid were not used.Postoperative patient-controlled intravenous analgesia was performed to maintain visual analogue scale≤3.The blood samples were collected for TEG and standard coagulation monitoring before dexmedetomidine and saline administration and 3 h after surgery.Results The temperature and hematocrit in the postoperative period were significantly less than the preoperative period in two groups (P＜0.01).In both groups,the activity of plasma antithrombin Ⅲ was significantly decreased and the concentration of plasma FDP was significantly increased in the postoperative period when compared with the preoperative period (P ＜0.01).In group D,the R time was significantly shortened and MA value was significantly increased in the postoperative period when compared with the preoperative period (P＜0.05) and there were no significant differences in the K time and α angle between the preoperative and postoperative period.In group C,the R and K time were significantly shortened and the value for MA and α angle were significantly increased in the postoperative period compared with the preoperative period (P＜0.01).The platelet counts,PT,APTT,and plasma fibrinogen concentration were comparable between the preoperative and postoperative period in both groups.The requirements of propofol and remifentanil in group D were significantly less than group C (P＜0.05).In the preoperative period,the plasma antithrombin Ⅲ activity,FDP concentration,and the values for all TEG variables were similar in both groups.In the postoperative period,the value for MA and the concentration of plasma FDP in group D were less than that in group C and the value for R and the activity of plasma AT Ⅲ in group D were more than group C (P＜0.05 or P＜0.01) and there were no significant differences in the K time and α angle in both groups.There were no significant differences in the temperature,hematocrit,platelet counts,PT,APTT,and plasma fibrinogen concentration in the preoperative and postoperative periods between the two study groups.Conclusion Adjunctive dexmedetomidine in general anesthesia could inhibit the decrease of R time and raise of the value for MA,inhibit the decrease of plasma an tithrombin Ⅲ activity and raise of FDP concentration,which indicated that dexmedetomidine can improve blood coagulation state after radical gastrectomy.

Objective To investigate whether the median(50%)effective effect-concentration(EC50)of propofol inducing loss of consciousness (LOC) varies. Methods 56 patients undergoing gastroscopy under general anaesthesia were enrolled on the study. Anaesthesia was conducted with a target-controlled infusion(TCI) of propofol. The initial target effect-site propofol concentration (Ceprop) was 5.00 μg/mL and was adjusted stepwise by 0.50μg/mL by an up-down sequential method to reach no-movement. Results Propofol EC50 to induce no-movement was higher in patients with anxiety than those without anxiety(6.46μg/mL vs. 5.75μg/mL,P<0.05). Conclusions During general anaesthesia ,patients with anxiety had a higher propofol EC50 for no-movement compared with those without anxiety. Differences in preoperative anxiety levels may reduce anaesthetic effects.

Objective:This study compared the prevalence,awareness,treatment and control of hypertension and associated factors in China and the United States(US).Methods:Adult data from nationally representative samples were derived from the Chronic Disease and Risk Factors Surveillance in 2010 and 2013 in China and the National Health and Nutrition Examination Survey in 2010 and 2013 in the US.Multivariable logistic and Poisson regression analysis were conducted to assess associations of the four outcomes with body weight status and behavioral factors.Results:Age-standardized prevalence rates of hypertension was 35.7％(95％confidence interval[CI]:35.4％to 36.1％)in 2010 and 29.8％(95％CI:29.4％to 30.2％)in 2013 in China,and 35.3％(95％CI:33.6％to 37.1％)in 2010 and 37.9％(95％CI:36.0％to 39.7％)in 2013 in the US.Among hypertensive participants,the age-standardized rates of treatment were 18.4％(95％CI:17.9％to 18.9％)in 2010 and 23.8％(95％CI:23.1％to 24.6％)in 2013 in China and 54.5％(95％CI:50.3％to 58.7％)in 2010 and 50.9％(95％CI:46.5％to 55.3％)in 2013 in the US;the age-standardized hypertension control rates were 3.2％(95％CI:3.0％to 3.5％)and 5.7％(95％CI:5.3％to 6.0％)in 2010 and 2013 in China and 50.6％(95％CI:46.2％to 55.0％)and 55.3％(95％CI:50.3％to 60.3％)in the US.Obesity was significantly associated with prevalence,awareness and control rates in both countries.Different from the US,obesity was negatively associated with hypertension control in China.Conclusion:Hypertension prevalence in China is similar to that in the US,but the control rate in China was significantly lower.Obesity was a critical risk factor for poor hypertension control in China.
