Objective To survey the prevalence of chronic obstructive pulmonary disease (COPD)in urban areas of Hunan province and relevant risk factors and provide a basis of the prevention and treatment for COPD. Methods A questionnaire survey was conducted among 4248 residents, aged over 15, by a simple cluster random sampling method in Changsha, Hunan, Wulipai street North Station community. All the respondents filled out an unified epidemiological survey questionnaire. All of the respondents received examination for lung function. Those respondents showed FEV1/FVC <70% were further examined by ECG,X ray inspection for differential diagnosis. The data of epidemiological survey was analyzed by multivariate logistic regression method. Results The response rate was 92%. The total prevalence of COPD was 4. 81%.The prevalence of COPD in the males was 6. 6%, and 3. 0% in the females. The prevalence of COPD in the males was significantly higher than that in the females (x2 = 29. 915, P < 0. 01). The prevalence increased with age increasing (P <0. 01). The more the education was, the lower the prevalence of COPD was. Risk factors analyzed with non-conditional logistic were as follow. The odd ratio (OR) for COPD in the age was 1.92(P <0. 01) and the odd ratio (OR) for COPD in the sex was 1.81 (P <0. 01). The weak lighting in house increased the risk with the OR of 4. 25(P <0. 01) and pet feeding further increased the risk with the OR of 12.08(P <0. 01). The odd ratio (OR) for COPD in the smokers was 1.74(P <0. 01) and the prevalence of COPD was related with smoking intensity (branch years of cigarette). Smoking intensity above 500 increased the risk of COPD. The passive smoking increased the risk with the OR of 16. 39(P <0. 01). The odd ratio (OR) for COPD in the paternal family history with chronic pulmonary disease was 2. 13(P <0. 01) and 2. 11 (P < 0. 01) in the maternal family history. The odd ratio (OR)for COPD in the education degree was 0. 52(P < 0. 01). Conclusions The prevalence of COPD was high in Changsha city, which might be attributed to the risk factors such as house lighting, pet feeding, cooking,aged, male, smoking, passive smoking, and family history. The education degree was the protective factor of COPD. We should intervene the relevant risk factors of COPD so that the prevalence of COPD might be cut down.

Objective To investigate the impact of exogenous of triiodothyronine (T3) on the liver hyperplasia of mouse. Methods Forty-ifve healthy speciifc pathogen free (SPF) C57BL/6 mice were divided into group A, B and control group using random number table method with 15 mice in each group. Mice in group A, B were respectively injected with 2 ml exogenous T3 solutions 10, 5μg/kg intraperitoneally. Mice in control group were injected with 2 ml normal saline. Three mice of each group were put to death respectively on day 0, 7, 14, 21, 42 after treatment. The total liver weight of the mice was measured after death. The proliferation of liver cells was detected by immunohistochemistry. The experimental data were compared using t test or analysis of variance. Results Compared with control group, the liver weight of mice in group A increased signiifcantly on day 7, 14, 21, 42 after treatment (t=3.298, 6.760, 7.119, 6.128;P<0.05) , and the liver weight of mice in group B increased signiifcantly on day 14, 21, 42 after treatment (t=4.188, 4.570, 2.978;P<0.05). The increased liver weight in group A was signiifcantly more than that in group B on day 7, 14, 21, 42 after treatment (t=4.935, 4.303, 4.033, 4.480;P<0.05). The liver weight in group A, B rose to the top on day 21 after treatment (F=21.480, 11.244;P<0.05). Compared with control group, the liver cell count in group A increased signiifcantly on day 0, 7, 14, 21, 42 after treatment (t=28.383, 23.842, 40.194, 31.059, 15.841;P<0.05), and the same with group B (t=9.097, 7.680, 20.597, 42.192, 14.415;P<0.05). The increased liver cell count in group A was signiifcantly more than that in group B (t=8.016, 4.872, 10.719, 9.514, 7.831;P<0.05). The liver cell count rose to the top in group A on day 14 after treatment (F=169.190, P<0.05) and rose to the top in group B on day 21 after treatment (F=90.460, P<0.05). Extensive proliferation of liver cells was observed both in group A and B after treatment. Conclusions Exogenous T3 can effectively promotes the liver hyperplasia of mouse, and the hyperplasia becomes more signiifcant as the T3 concentration rises.

ObjectiveTo investigate the influencing factors of portal vein thrombosis (PVT) after splenectomy in patients with portal hypertension.MethodsClinical data of 67 patients with liver cirrhosis and portal hypertension undergoing splenectomy + endoscopicvariceal ligation in Lingnan Hospital, the Third Affiliated Hospital of Sun Yat-sen University between March 2012 and April 2015 were retrospectively studied. Among the 67 patients, 47 were males and 20 were females with the average age of (47±8) years old. Thirty-five patients underwent laparoscopic splenectomy and 32 patients underwent open splenectomy. The informed consents of all patients were obtained and the local ethical committee approval had been received. The patients were divided into the PVT group and the non-PVT group according to whether PVT developed after surgery. The influencing factors of PVT in two groups were compared. The comparison of the influencing factors of PVT was conducted usingt test or chi-square test.ResultsEleven cases developed PVT after splenectomy with the incidenceof 16% (11/67) including 6 cases of laparoscopic splenectomy and 5 of open splenectomy. The incidence of PVT was associated with Plt and the concentration of D-dimer in blood circulation. Blood Plt of the PVT group was (739±39) ×109/L, which was significantly higher than (318±51)×109/L of the non-PVT group (t=14.678,P<0.05). The concentration of D-dimer of the PVT group was (7.4±1.1) mg/L, which was significantly higher than (4.0±0.9) mg/L of the non-PVT group (t=5.458, P<0.05). The incidence of PVT was not associated with surgical procedure (χ2=0.028,P>0.05).Conclusion The incidence of PVT after splenectomy is associated with Plt and the concentration of D-dimer and is not associated with surgical procedure.

ObjectiveTo investigate the application value of laparoscopic splenectomy combined with endoscopic variceal ligation in cirrhosis and portal hypertension.MethodsSixty-three patients with cirrhosis and portal hypertension undergoing laparoscopic splenectomy combined with endoscopic variceal ligation in Lingnan Hospital, the Third Afifliated Hospital of Sun Yat-sen University between September 2011 and September 2014 were included in the prospective study. The patients were randomized into the laparoscopy group and the laparotomy group according to different surgical procedures. Among the 28 patients in the laparoscopy group, 25 were males and 3 were females with the age ranging from 40 to 69 years old and the median of 55 years old. Among the 35 patients in the laparotomy group, 32 were males and 3 were females with the age ranging from 43 to 69 years old and the median of 53 years old. The informed consents of all patients were obtained and the local ethical committee approval had been received. The patients of two groups underwent endoscopic variceal ligation during the splenectomy. The duration of operation, intraoperative blood loss, length of hospital stay, treatment costs and incidence of postoperative complications of two groups were observed. The comparison of the observed indexes of two groups was conducted usingt test and the rate comparison was conducted using Fisher's exact test.ResultsAll the patients completed the surgery successfully. The duration of operation and the intraoperative blood loss were (113±8) min and (204±52) ml for the laparoscopy group, and were (106±6) min and (226±63) ml for the laparotomy group where no significant difference was observed (t=1.97,-0.75;P>0.05). The length of hospital stay and treatment costs of laparoscopy group were (6.0±1.2) and (35 000±3 000) RMB, which were signiifcantly lower than (11.2±2.7) and (45 000±1 000) RMB of laparotomy group (t=-4.87,-6.81;P<0.05). Eight patients in the laparoscopy group developed complications, among them, 7 were with portal venous thrombosis and 1 was with recurrent hemorrhage. Seventeen patients in the laparotomy group developed complications, among them, 10 were with portal venous thrombosis and 7 were with fat liquefaction of incisions. The incidence of fat liquefaction of incisions in laparoscopy group was signiifcantly lower than that of the laparotomy group (P=0.035).ConclusionLaparoscopic splenectomy combined with endoscopic variceal ligation can achieve the similar curative effect with laparotomy and has the advantages of small operational wound, quick recovery, less complications, as well as shorter length of hospital stay and lower total treatment costs.
