Objective In order to master the current prevalence situation of dilated cardiomyopathy in Yunnan Province.Methods An investigation of dilated cardiomyopathy was carried out in 17 counties from August to December in 2011 in non-Keshan disease areas.Two townships (towns) that similar to Keshan disease areas in natural environment,pattern of production and lifestyle in non-Keshan disease areas were selected in each project county,and 1 village was selected as surveillance site in each selected township(town).The number of resident in each village no less than 500 people was appropriate and deficiency was supplemented from neighboring villages.The sampling rate was no less than 80％.Clinical examination and electrocardiographic tracings were carried out.The patients with suspected dilated cardiomyopathy and latent Keshan disease were taken anteroposterior chest X-ray in accordance with the National Non-Keshan Disease Area Dilated Cardiomyopathy Condition Survey Program.The surveillance was carried out based on The National Investigation Scheme of Dilated Cardiomyopathy in Non-Keshan Disease Areas.Cases were diagnosed based on the diagnostic standard of dilated cardiomyopathy and suspected latent Keshan disease.Results In the 34 villages of 17 selected counties,14 545 people were investigated.Twenty-six cases of latent dilated cardiomyopathy and suspected latent Keshan disease were detected,and the total detection rate was 17.88/million.One case was dilated cardiomyopathy,and 25 cases were suspected latent Keshan disease,detection rates were 0.69/million and 17.19/million,respectively.Male and female cases were 15 and 11,respectively.The ratio of people aged 65 and older accounted for 42.31％(11/26),among them suspected latent Keshan disease accounted for 44.00％(11/25),and 1 case of dilated cardiomyopathy was in the 45 to 54 years old group.Electrocardiographic examination of 14 519 people,the abnormal rate was 8.13％(1 180/14 519).Among 112 chest X-ray films,104 cases had a cardiothoracic ratio less than or equal to 0.50,4 cases from 0.51 to 0.55,3 cases from 0.56 to 0.60,and 1 case more than or equal to 0.61.Conclusion The detection rate of dilated cardiomyopathy cases is lower in non-Keshan disease area of Yunnan Province,but suspected latent Keshan disease is detected.

Objective To master the current situation of Keshan disease(KD) and its trend in Yunnan Province,and scientifically evaluate the control and prevention measures.Methods According to the 2011 Endemic Disease Prevention and Control Project Implementation Plan and National Keshan Disease Mornitoring Program,choose Eryuang,Dali,Xiangyun,Wuding,Nanhua,Chuxiong and Mouding Counties(Cities)in Yunnan Province,that were seriously affected by Keshan disease,monitoring was carried out; 2 towns were selected in each county,and 1 village was selected as surveillance site in each selected town.All the residents were clinically examined and Electrocardiography tracing was taken.Suspected cases were given filmed chest X-ray and color echocardiography.KD cases were correctly diagnosed according to the diagnostic criteria.Results A total of 6 022 residents were investigated in the 14 investigation sites; 25 cases of KD were found,and the total incidence rate was 0.42％.Among the 25 KD cases,22 cases were latent KD,and the incidence rate was 0.37％; women(15 cases) were more than men (10 cases),and 10 patients were 3-14 years old,accounted for 40.00％(10/25).Potential KD 22 cases,including 10 cases of 3-14 years old; slow type of KD 3 cases,including 2 cases 45-54 years old.Electrocardiographic examination 6 022 residents,the abnormal rate was 20.44％.Among 32 X-ray films,28 cases had a cardiothoracic ratio less than or equal to 0.50,2 cases from 0.51 to 0.55,1 case from 0.56 to 0.60,and 1 case more than or equal to 0.61.Conclusions The results of KD surveillance have presented a downward trend in Yunnan Province,and the incidence rate of KD is lower.But the pathogenic factors are still active,which is harmful to children health in KD areas.In future,surveillance of children KD should be strengthened,control measures should be implemented,in order to guarantee the health of people who lived in KD areas.

Objective To discuss the efficiency of fibrin glue amikacin complex in controlling infection by observing the changes of leukocyte and neutrophilic granulocyte classifying counts after fibrin glue amikacin complex treated deep wound. Methods Clinical case-control study was used in the study. All patients were divided randomly into test group (100 patients) and control group (100 pa-tients), matched by wound location, wound size, time from injury to operation, combined injury and gen-eral antibiotics use to compare leukocyte and neutrophilic granulocyte classifying counts between both groups and observe possible toxic and side-effect in test group. Results Firstly, the test group and control group had the comparability in aspects of gender distribution, average age and injury mechanism (P >0.05). Secondly, there was statistical difference in classifying counts of leukocyte and neutrophilic granulocyte in the test group at different time points (P <0.05). The classifying counts of leukocyte and neutrophilic granalocyte peaked at 24 hours after operation, then decreased with treatment time and reached the lowest at 24 days after surgery or at day 1 before discharge. Thirdly, there existed statistical significance upon leukocyte counts in the test group and control group except for at day 1 after operation (P > 0.05), with lower counts in test group than control group. In aspect of neutrophil classifying counts, there was statistical significance (P < 0.05) at other time points in beth groups except for time points at days 1,2 and 12 (P >0.05). The test group had lower neutrophil classifying counts compared with con-trol group at different time points. Conclusion The fibrin glue amikacin complex has good clinical effort and high security, with no toxic or side effort in treatment of deep wound infection, and is worth clinical applicaiton.

Objective:To explore the efficacy of low-dose computed tomography (LDCT) baseline and follow-up scans of lung cancer screening and to analyze lung nodules and other thoracic lesions detected from baseline and follow-up. Methods:A total of 650 sub-jects were enrolled in the LDCT lung cancer screening program, and investigators mainly focused on the analysis of 548 subjects who participated in the follow-up scan. The investigators recorded the nodules and other lesions of baseline screening, compared them with the follow-up images, and recorded their progress. Results:A total of 101 subjects were positive in the baseline screening, with a positivity rate of 18.4%. Six cases of lung cancer were confirmed by pathology, with a detection rate of 0.92%(6/650). The detection rate of lung cancer in female non-smokers (1.59%) was higher than that in male smokers (1.04%) without significant difference (P=0.624). Detected in the follow-up scan were 19 cases of new nodule-positive subjects. The positive rate for new nodules was 3.5%(19/548). The difference between the three-and two-dimensional levels was statistically significant. Conclusion:The effect of LDCT screen-ing for early lung cancer is significant. The detection rate in female non-smokers was not significantly higher than that in male smok-ers. Thus, LDCT lung cancer screening is equally significant for both sexes. The computer-aided detection (CAD) volume measurement technique is better to evaluate the progress of nodules during the follow-up interval.
