Objective To better promote the health education and health promotion among patients with chronic disease, general practitioners (GPs) in the community should master the knowledge of non-communicable diseases (NCDs). This paper aimed to describe the current situation of GPs' knowledge about prevention and treatment of NCDs. Methods Self-designed questionnaires were issued to 1 077 GPs in community health service centers, and all GPs finished the questionnaire without assistance. The content of questionnaire includes the general information of GPs and six questions focusing on NCDs. Results Overall, 1 076 GPs completed the questionnaire, and the response rate was 99.9% (1 076/1 077). With regard to the six questions about NCDs, 90.4% (973/1 076) of GPs were well aware of the diagnosis of hypertension. Apart from that, the knowledge of diabetes mellitus (60.9%, 655/1 076), factors related to NCDs (70.2%, 755/1 076), the concepts of mental illness (52.0%, 560/1 076) and the clinical significance of tumor markers (87.9%, 946/1 076) among GPs were adequate, while more than half of the GPs did not know a lot about home oxygen therapy. Conclusion The mastering level of knowledge about prevention and treatment of NCDs among GPs varies that they need further improvement.

The teaching methods were explored to improve the quality of medical genetic teaching for foreign students according to the common problems during the teaching process. The negative effects of communication barriers in medical genetic teaching could be reduced by interactive teaching or problem-based learning in groups,in which the ability to resolve problems by themselves could be improved. In order to improve the teaching systematicness and teaching quality,the teaching contents in class should be from simple to deep,covering genetic laws,pathogenesis,diagnosis and control measure of genetic diseases. From the perspective of practical application and combining with the construction of self-de-signed teaching textbook and cases, the quality of medical genetic teaching ultimately could be further improved.

This study was to appraise safety and feasibility of laparoscopic approach and investigate the clinical effects of laparoscopic tension-free repair of esophageal hiatal hernia using mesh. From August 2006 to July 2009, 24 patients with esophageal hiatal hernia underwent laparoscopic repair. Twenty-three patients received laparoscopic tension-free repair using mesh, at the same time, Toupet or Dor partial fundoplication was performed. One patient was converted to open surgery. The average operating time was 90 min (70-210 min) and the blood loss was between 10-110 mL. There was no death. The mean postoperative hospital stay was 5 days (3-30 days). During a follow-up period of 12-20 months (mean 15 months), there was no recurrence of the hernia, and no complication with use of mesh. The present study suggested that laparoscopic approach was secure and minimally invasive operation for esophageal hiatal hernia and the use of mesh could reduce recurrence rate.

Objective To evaluate the tissue motion tracking of mitral annular displaeement(TMAD) method in the assessment of short-term effect of cardiac resynchronization therapy (CRT). Methods Twenty six chronic heart failure (CHF) patients with CRT were detected by TMAD. The maximal displacement of the six points of mitral annulus(DS), the standard deviation of the time to regional peak systolie displacement of the six points (Td-sd) and the maximal temporal difference of any two points(Tds-diff) were compared before and one month after CRT. And the correlation between mean displacement and left ventricular ejection fraetion(LVEF),left ventricular end systolic volume(LVESV), fraction area change (FAC) was analyzed. Results Compared with the pre-operatively, the displacement and the mean displaeement of the six points of mitral annulus were significantly increased(P<0.01),Tds diff and Td-sd were decreased(P<0.05) one month after CRT. TMAD correlated with LVEF,LVESV and FAC (r =0.419, r = 0.529, r = 0.567, P <0.05) one month after CRT. Conclusions TMAD is a new technology to evaluate the short-term effect of CRT.

Objective To investigate the levels of blood pressure, blood lipid, blood glucose, body mass index (BMI) as well as the epidemiological characteristics of dyslipidemia, hyperglycemia, hypertension and metabolic syndrome of Hangzhou citizens. Methods A total of 28 990 citizens in Hangzhou city who underwent health checkup were recruited in this study, including 10 179 males and 18 811 females. The average age of subjects was 65.05 years. Subjects were asked to complete questionnaires regarding personal characteristics. The physical examination emphasized measurement of height, waist and blood pressure. Blood samples were collected and subjected to serum glucose, TC, HDL-C, LDL-C and TG measurements. The values of the examinations was described as xˉ± s . The ratios were compared with chi-square test. The trend analysis was conducted by linear correlation test. Results The prevalence of hypertension and metabolic syndrome was 17.1% and 11.2% respectively. And the prevalence of overweight/obesity and hyperglycemia was 36.3%,8.1%,16.4%respectively. It was indicated that the men had higher prevalence of hyperglycemia, hypertension, metabolic syndrome and overweight compared with women. However, as to the dyslipidemia, men and women were totally different. Women were more prone to suffer from hypercholesterolemia and elevation of low-density lipoprotein cholesterol. Men were apt to suffer from hypertriglyceridemia and reduction of high-density lipoprotein cholesterol. Divided the subjects by age into three groups, it was suggested that the rates of dyslipidemia, hyperglycemia, hypertension and overweight/obesity increased along with the increment of age in women. Although the rates of metabolic disorders were higher in the group of men, the trend of increase with age was not as significant as in women. It could be seen in men that dyslipidemia and overweight/obesity were reduced with the increase of age. Conclusion The metabolic disorders in Hangzhou citizens showed their own characteristics. It is suggested that multiple strategies targeting at different sexes and age-groups should be formulated to prevent and control the occurrence of metabolic diseases.

OBJECTIVETo test the different contrctile responses of extracellular nucleotides, such as ATP, UTP and nucleotide uridine adenosine tetraphosphate (Up4A) in gastric longitudinal muscle (LM) and circular muscle (CM). Examined the effect of P2X and P2Y receptor antagonists (in this study, we used IP5I and suramin) and cyclooxygenase inhibitor (indomethacin) on Up4A induced contractile responses in LM and CM.

METHODSThe rats were sacrificed and the stomachs were opened to gain LM and CM. Using organ bath system to assess contrctile responses of smooth muscle.

RESULTSUp4A could induce contractile responses in both CM and LM, which were similar with ATP and UTP. IP5 did not attenuate Up4A could induce contractions in both LM and CM, but suramin and indomethacin significantly inhibited Up4A contraction in CM, but not in LM.

CONCLUSIONOur results suggest that extracellular nucleosides and their inhibitors induce different responses between LM and CM.

Objective To evaluate laparoscopic local resection for the treatment of gastric tumors. Methods The clinical data of 78 patients who received laparoscopic local resection at the PLA General Hospital from February 2006 to January 2010 were retrospectively analyzed. According to the tumor site and free range, total laparoscopic gastrectomy was applied to 45 patients, laparoscopic local resection was applied to 22 patients, laparoscopic and endoscopic tumor resection was applied to 11 patients. The efficacies of the surgical approaches were investigated. Results Laparoscopic local resection was successfully performed on the 78 patients without conversion to open surgery. The mean operation time and operative blood loss were 75 minutes (range, 45-120 minutes) and 60 ml (range, 35-90 ml), respectively. The mean diameter of the tumor was (2.5±1.3)cm (range, 0.7-4.8 cm). No mortality or morbidity occurred postoperatively. The bowel function recovery time and the duration of hospital stay were 35 hours (range, 25-42 hours) and 7.5 days (range, 6-9 days), respectively. The results of postoperative pathological examination verified that 63 patients were with gastric stromal tumor, 11 patients were with benign gastric diseases, including 5 with gastric heterotopic pancreas, 2 with inflammatory pseudotumor, 2 with hyperplastic polyp, 1 with schwannomas and one with angioma. Four patients were with carcinoid, 3 carcinoids were located in mucous layer and 1 invaded into muscular layer. The median time of follow-up was 26 months, and no anastomotic stenosis or port-site metastasis was observed. Of the 63 patients with gastric stromal tumor, 2 were treated with imatinib mesylate, 1 had tumor recurrence and received reoperation. Conclusion Laparoscopic local resection is safe and feasible for the treatment of benign gastric neoplasms, stromal tumor and early gastric tumors.
