ObjectiveTo investigate the effectiveness of the modified Urbaniak operation to treat avascular necrosis of the femoral head (ANFH). MethodsA retrospective analysis was made on the clinical data of 38 patients (41 hips) with ANFH treated between February 2010 and October 2012 with the modified Urbaniak operation (to add lateral femoral incision based on femoral greater trochanter incision, to preserve the original fibula flap drilling, decompression and filling through trochanteric outer cortex, and to select the descending branch of lateral circumflex femoral artery as the supply vessel). Of 38 cases, 25 were male (28 hips), 13 were female (13 hips), aged 16-52 years (mean, 34 years); there were 19 cases (21 hips) of alcoholic ANFH, 9 cases (9 hips) of traumatic ANFH, 5 cases (6 hips) of hormone ANFH, and 5 cases (5 hips) of idiopathic ANFH. The disease duration ranged from 10 months to 6 years (mean, 3.7 years). According to Ficat staging criteria, 24 hips were rated as stages II and 17 hips as stage III. The preoperative Harris hip scores were 80.63±5.02 and 77.06±6.77 in patients at stage II and III respectively. The related complications were recorded after operation. According to the findings of postoperative X-ray films, 4 grades were improvement, stabilization, deterioration, and failure; improvement or stabilization was determined to radiological success. According to the Harris score to evaluate the function of hips, more than 80 was determined to clinical success. ResultsHealing by first intention was achieved in all patients after operation. Three cases had numbness and hypoaesthesia of the lateral femoral skin, 1 case had abnormal sensation of the dorsal foot, which had no effect on daily life. Thirty-eight cases (41 hips) were followed up 1 year to 3 years and 3 months (mean, 2 years and 3 months). There was no complication such as hip joint stiffness, hip or groin persistent pain, hip joint infection, or ankle instability. At last follow-up, the X-ray films showed improvement in 23 hips (56.1%), stabilization in 17 hips (41.5%), and deterioration in 1 hip (2.4%); 40 hips obtained the radiological success. According to the Harris score, the results were excellent in 17 hips, good in 20 hips, fair in 3 hips, and poor in 1 hip with an excellent and good rate of 90.2%; 37 hips achieved the clinical success. The Harris scores were 89.92±4.12 and 86.53±5.70 in patients at stage II and III respectively at last follow-up, showing significant differences when compared with preoperative ones (t=7.011, P=0.000;t=4.412, P=0.000). ConclusionThe modified Urbaniak operation has the advantages of more convenient operation, less complications, higher safety, and better hip functional recovery. It is an effective method to treat ANFH.
ObjectiveTo explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults. MethodsBased on the data from the China Health and Nutrition Survey (CHNS), as well as the consumption level and altitude data from the National Bureau of Statistics and government official website, a robust multilevel Poisson regression was performed to explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults, according to data and design types. ResultsAccording to the inclusion and exclusion criteria, 11 579 subjects and totaling 50 957 lines of data were enrolled. The 24 years follow-up results indicated that the crude incidence density of hypertension was 37.08/1 000 person years, with 40.51/1 000 person years for males and 34.13/1 000 person years for females. The robust multilevel Poisson regression results indicated that, by adjusting the high-level factors such as time, the proportion of the community mainly engaged in agricultural labor, and the consumption level of subjects, as well as sociodemographic characteristics such as age and gender, the Middle (RR=1.20, 95%CI 1.04 to 1.39), Northeast (RR=1.25, 95%CI 1.03 to 1.52), and Eastern (RR=1.25, 95%CI 1.05 to 1.48) China had a higher risk of developing hypertension than the Western China. The risk of hypertension in urban area was lower than that in rural area (RR=0.87, 95%CI 0.77 to 0.96). ConclusionThe incidence density of hypertension in China is relatively high, and male is higher than female. The incidence of hypertension in the Western China is lower than that in the Middle, Northeast and Eastern China, and urban area is lower than rural area.
ObjectiveTo investigate the prevalence and risk factors of chronic obstructive pulmonary disease (COPD) in urban and rural male residents of Chengdu city. MethodsA cross-sectional survey about the incidence of COPD using cluster random sampling methods was carried out from February to December 2010 among male residents aged 40 to 70 years in four communities in Chengdu city, which was conducted by applying questionnaire survey, physical examination, portable spirometry, etc. Data was analyzed by using SPSS 18.0 software, and the risk factors were also analyzed by using the multivariate logistic methods. ResultsA total of 631 male residents were included, 301 urban and 330 rural. The results showed that: after population standardization, among male residents aged 40 to 70 years in four communities in Chengdu city, the overall prevalence of COPD was 7.95%, and the prevalence was 12.07% in rural area and 7.05% in urban area (P < 0.001). The results of multivariate logistic regression analysis showed that area, age, BMI and smoking volume were the main risk factors of COPD among male. ConclusionThe prevalence of COPD in Chengdu city is relatively higher, which is much higher in rural area than that in urban area. The risk factors are various, and thus comprehensive prevention and treatment of COPD should be emphasized.
ObjectiveTo investigate the prevalence status and characteristics of dyslipidemia and cardiovascular risk factors in urban communities of Chengdu city. MethodsBy cluster sampling, a population of 994 inhabitants were selected from 14 urban communities in Chengdu city between February and October 2010. We investigated patients between 35-70 years old who lived in the area over 2 years, by using questionnaires survey, physical examination, and laboratory tests. According to the age, the respondents were divided into three groups: young group ( ≤ 44 years old), middle-aged group (45-59 years old) and elderly group ( ≥ 60 years old). We further investigated the major cardiovascular risk factors for hyperlipidemic patients. ResultsThe prevalence of dyslipidemia in Chengdu urban area was 28.47% (283/994), and standardized prevalence rate was 24.65% (male, 24.68%; female, 30.91%). The prevalence rate between male and female had significant diTherence (χ2=4.513, P=0.034). Female elderly group and middle-aged group had a significantly higher prevalence than the young group (P<0.05), while the male prevalence had no statistical diTherences among all age groups (P>0.05). Hypertension was most common in patients with dyslipidemia (male, 50.04%; female, 52.41%) followed by diabetes and coronary heart disease. There was no difference between male and female in the prevalence of dyslipidemia accompanied hypertension, history of stoke and coronary heart disease, abdominal obesity,or obesity (P>0.05). Higher prevalence with smoking and drinking was in male patients (P<0.05). ConclusionThe prevalence of dyslipidemia is relatively high in urban communities of Chengdu city. According to the region of hyperlipemia epidemiological characteristics and risk factors, by using comprehensive intervention measures, we can reduce the prevalence of dyslipidemia.
ObjectiveTo investigate the status-quo of urban and rural residents' depression in the communities of Chengdu city and its influencing factors. MethodsA multi-stage stratified cluster sampling survey was carried out from February to October 2010. Residents aged from 35 to 70 years in 4 urban and rural communities of Chengdu were investigated in the incidence of depression. The health survey questionnaire and PHQ-2 Depression Screening Scale were used for the household investigation. Data was analyzed using SPSS 18.0 software, and the risk factors were also analyzed using multivariate logistic methods. ResultsA total of 2 027 residents were interviewed, including 1 015 urban (616 women and 399 men, with mean age of 58.90 ±9.48 years) and 1 012 rural residents (582 women and 430 were men, with mean age of 54.94 ±9.64 years). The results showed that the overall depression prevalence rate of residents aged from 35 to70 years old in Chengdu was 2.91% (59/2 027); and the prevalence was 4.33% (44/1 015) in urban and 1.48% (15/1 012) in rural. The prevalence was significantly higher in urban areas than that in rural areas (χ2=13.296, P < 0.001). The results of multivariate analysis showed that a significant difference was found in the prevalence of depression among the different marital status groups, and more divorced people suffered from depression. No statistically significant correlation was found between the factors (including occupation, education level and family income status) and depression. ConclusionThe prevalence of depression among residents in urban and rural communities of Chengdu was high, and the divorced population should be paid more attention to in the prevention and treatment of depression.
ObjectiveTo evaluate the reasonableness of anticoagulation management strategy in patients after mechanical heart valve replacement. MethodsAll patients were followed and registered continually at outpatient clinic from July 2011 to February 2013, with a minimum of 6 months after surgery. Targeted international normalized rate (INR) 1.60 to 2.20 and warfarin weekly dosage adjustment were used as the strategy of anticoagulation management. Except bleeding, thrombogenesis and thromboembolism, time in therapeutic range (TTR) and fraction of TTR (FTTR) were adopted to evaluate the quality of anticoagulation management. ResultsA total 1 442 patients and 6 461 INR values were included for data analysis. The patients had a mean age of 48.2±10.6 years (14-80 years) and the following up time were 6 to 180 months (39.2±37.4 months) after surgery. Of these patients, 1 043 (72.3%) was female and 399 (27.7%) was male. INR values varied from 0.90-8.39 (1.85±0.49) and required weekly doses of warfarin were 2.50-61.25 (20.89±6.93 mg). TTR of target INR and acceptable INR were 51.1% (156 640.5 days/306 415.0 days), 64.9% (198 856.0 days/306 415.0 days), respectively. FTTR of target INR and acceptable INR were 49.4% (3 193 times/6 461 times), 62.6% (4 047 times/6 461 times). There were 8 major bleeding events, 7 mild bleeding events, 2 thromboembolism events, and 2 thrombogenesis in the left atrium. ConclusionIt is reasonable to use target INR 1.60-2.20 and warfarin weekly dosage adjustment for patients after mechanical heart valve replacement.
ObjectiveTo evaluate the smoking environment, its related knowledge and difference between urban and rural areas in Chengdu. MethodsIn December 2010, we randomly sampled and investigated 60 dwellers aged from 35 to 70 from urban and rural communities, who were 1:1 paired by the age and sex. Questionnaires survey was used. ResultsThere were 48.3% (29/60) dwellers thought that smoking should be allowed freely at home, of which 30.0% (9/30)rural homes had no rules about smoking prohibited. There were 93.3% (28/30) urban dwellers supported male smoking. About 86.7%-98.3% urban dwellers realized that many diseases such as heart disease, stroke, and lung cancer may be due to smoking. And 16.7% urban dwellers also realized that cigarettes can result in diabetes mellitus, but none of rural dwellers did. The publicity of smoking cessation among urban dwellers (91.7%) by mass media was better than rural ones (0.0%). There were 95.0% dwellers denied any institution or organization for smoking control. ConclusionThe dwellers were short of cognition about restrictions of smoking environment and non-smoking knowledge. It's different between urban and rural area in tobacco advertisement and publicity of smoking cessation. We should continue enhancing public education, forbiding tobacco advertisement and providing institutions for smoking control.
Objective To analyze the current status of health insurance policies for outpatient chronic diseases among urban and rural residents in Sichuan Province and provide policy recommendations for improving their management. Methods Health insurance policies for outpatient chronic diseases across 21 coordination districts in Sichuan Province were systematically reviewed by computer. Descriptive analysis was employed to compare differences in disease coverage, classification management, eligibility criteria, and benefit levels. Results In Sichuan Province, the number of outpatient chronic and special diseases across its 21 coordination areas ranged from 41 to 77. The coverage of these diseases varies included <10%, 10%–49%, 50%–99%, and 100%, and the diseases were managed under 2, 3, or 4 categories. There were also significant variations in disease recognition criteria and the level of benefit protection among the different coordination areas. Conclusions Significant disparities exist in outpatient chronic diseases policies and management practices among the 21 coordination districts in Sichuan Province. To address this, we recommend standardizing the provincial outpatient chronic diseases catalog, eligibility criteria, and classification management. Additionally, benefit levels should be optimized and regional disparities gradually reduced under the premise of maintaining balanced medical insurance fund risks.
ObjectiveTo provide policy suggestions concerning the distribution of health resources between urban and rural areas and management and education of diabetes, this study depicted the current status of access to healthcare and analyzed its determinants among Chinese diabetic patients.MethodsMultivariate ordinal logistic regression and multivariate binary logistic regression were employed to analyze the effects of socioeconomic status and urban-rural disparities on health access.ResultsMultivariate results suggested that urban patients were more likely to conduct more blood glucose tests (P<0.000 1) and receive more self-care suggestions from physicians (P=0.02). After controlling all other covariates, patients graduated from secondary schools and those with vocational school degrees or above were 1.61 and 2.44 times more possible to take more blood glucose tests.Conclusions There exists significant urban-rural disparities of access to healthcare among Chinese diabetic patients. Education may be a key factor of access to healthcare among Chinese diabetic patients. It’s highly recommended to implement education programs on diabetes management in rural areas, where the education status and demographic factors should be considered. The distribution of health resource in rural areas requires more policy and governmental support.
ObjectivesIn order to provide baseline data for the establishment of urban health indicator system in China and other cities, the indicators, characteristics and problems of 24 urban health indicator systems in China were researched.MethodsCNKI, Wan Fang Data, VIP, as well as China’s all provinces and cities’ websites of government and family planning commission and patriotic health campaign commission were searched to collect literatures and government documents on " Healthy city” and its index system. They were then been extracted, classified and summarized.ResultsThe final search involved 24 healthy city indicators system in China, including 1 531 indicators and 14 dimensions, 5 operations and 8 special operations. Seven dimensions (health, health services, environmental health, social indicators, indicators of policy, indicator of health promoting) were widely used. 38 indicators were used above five times, while 441 indicators were used merely once.ConclusionsThe structure of urban health indicator systems in China are almost consistent with WHO’s. They all have the characteristics of diversity, characteristic, national policy, civilian etc. However, there still exists problems with indicators of quantity, definition, classification and lack of indicators on mental health, children health, pregnant woman health as well as elderly health. It is urgent to develop the principles, methods, processes and standards for urban health indicators.
