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.
There are more than 6 800 urban public hospitals in China, which are the main subject of our country's medical service, but the process and efficiency need to be improved because of the siphon effect of resources and the limit of service scope. The use of internet thinking and technology will solve this problem effectively. Based on the fact, Deyang People's Hospital planned "internet+" system according to the requirement of the medical and health system reform, to solve the problems such as service efficiency, doctor-patient communication, multi-spot disciple, hierarchical medical system, delicacy management, etc. Through the concrete practice of elevating the efficiency of outpatient and emergency care services, it is recognized that the application of internet thinking and technology can not only accelerate the medical and health system reform, but also subvert the traditional medical pattern, integrate the regional medical resource, and enlarge the scope of medical services. It provides a sharp weapon to push forward the reform of urban public hospitals.
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.
ObjectiveTo investigate the prevalence and risk factors for hypertensive women in Chengdu communities, as well as the urban-rural differences.
MethodsCluster random sampling method was used. Cross-sectional data on questionnaire for physical examination and laboratory tests were collected from study of 1 202 women in urban and rural Chengdu between February and October 2010.
ResultsThis study enrolled the total of 1 202 women aged from 35 to 70 in Chengdu communities, where 616 were from urban areas and 586 from rural areas. Of them, 402 had hypertension with an overall prevalence rate of 33.44% and with the standardized prevalence of 35.27%. The prevalence of hypertension in urban women (42.86%) was higher than that of rural women (23.55%); the difference was statistical (χ2=13.057, P<0.001). The prevalence of hypertension increased with the age increase. The highest cardiovascular risk factors coexisted with hypertensive women was high waist circumference (abdominal obesity), followed by triglyceride (33.33%), total cholesterol (TC) (33.08%), impaired glucose tolerance (38.86%), impaired fasting glucose (IFG) (24.38%), body mass index (16.67%), and high density lipoprotein cholesterol (0.75%). The urban hypertensive women had higher the ratio and average of high waist circumference, IFG and TC than thoes from rural areas with a statistically difference (P<0.05).
ConclusionHypertension prevalence in women from rural areas is higher than that in women from urban areas. The urban hypertensive women has higher ratio of risk factors than thoes from rural areas.
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.
ObjectiveTo investigate the status and problems of facility allocation in 22 health service centers and township health centers in Fucheng District of Mianyang city, in order to provide references for improving health services in these medical units.
MethodsAccording to the national guidance of facility configuration in township hospitals, the questionnaire was made to survey on the allocation of medical facilities, durable years and frequency of use in 22 medical units of Fucheng district (11 urban community health service centers and 11 township health centers) from November to December 2010. The descriptive and stratified analysis was performed for the survey results.
ResultsMost equipment and facilities required in "Guide Criteria for Installation of Equipment and Facilities in Urban Community Health Service Centers" including facilities for diagnosis, treatment and health education were not installed and there were problems of poor property and low frequency of use. The medical equipment was seriously inadequate in 11 township health centers.
ConclusionCommunity basic equipment resource should be improved as soon as possible.
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 investigate the prevalence and risk factors of hypertension in urban and rural residents in Chengdu.
MethodsA cluster random sampling survey was carried out from February to October in 2010. A total of 2 011 residents aged 35-70 years in four communities of Chengdu (two communities in urban area, two in rural area) were investigated for the incidence of hypertension. Analysis was performed using SPSS 18.0 software.
ResultsThe standardized prevalence of hypertension was 31.30% among residents aged 35-70 years, which was much higher in urban than that in rural:39.03% vs. 24.90% (P < 0.05). The results of multivariate logistic regression analysis showed that, age, waist, heart rate, fasting blood glucose and education level were the major risk factors of hypertension for male; while age, waist, heart rate, fasting blood glucose, triglyceride and uric acid were the major risk factors for female.
ConclusionThe prevalence of hypertension in urban is higher than that in rural in Chengdu. Prevention and intervention should be performed more for whom have increased waist circumfluence, abnormal levels of fasting glucose, and increased heart rate.
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.
