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.
Objective To investigate pre-hypertension in aspects of its incidence, accompanied cardiovascular risk factors, and difference between urban and rural areas in Chengdu. Methods By cluster random sampling method, a total of 2 011 patients aged 35-70 years from urban and rural communities in Chengdu were selected as respondents. The investigation was conducted through questionnaire, physical examination and laboratory tests, so as to find out the main cardiovascular risk factors of pre-hypertension. All data were dual input into computer by a specially-assigned person. SPSS 13.0 software was used for analysis, Chi-square test was adopted for categorical data, and Plt;0.05 was taken as an index for significant difference. Results a) The incidence rate of pre-hypertensive in Chengdu was 33.6%, and it was 45.67% and 46.31% in urban and rural areas, respectively. In rural area, more male (51.04%) were affected than female (42.83%). b) The smoking population with pre-hypertension were mainly the male, and the ratio of rural male was 60% (132/220), far higher than that of urban male which was 32.6% (59/181). c) The pre-hypertensive population accompanied with diabetes was higher in urban (27.97%) than rural (14.01%). d) The pre-hypertensive population accompanied with hypercholesterolemia or low HDL was 33.04% (150/454) in urban, as twice as that in rural which was 16.41% (76/471). e) The pre-hypertensive population accompanied with abdominal obesity was far higher in urban (28.41%) than rural (12.74%). Conclusion Smoking is the risk factor which needs to be primarily intervened for male hypertensive patients in rural area. Impaired glucose tolerance is the common risk factor for both urban and rural residents, and hyperlipidemia is the most primarily risk factor for urban pre-hypertensive patients, followed by diabetes, and abdominal obesity.
Objective To investigate the prevalence of hyperuricemia and the current status as well as differences of cardiovascular risk factors in hyperuricemia patients between urban and rural areas in Chengdu. Methods We randomly sampled 2 032 patients aged from 35 to 70 years age in urban and rural communities, using a questionnaire, physical examination and laboratory tests. Results a) The prevalence of hyperuricemia was 17.77%, which was higher in urban residents (21.38%) than that in rural residents (14.16%). b) The prevalence of hyperuricemia associated with hypercholesterolemia was higher in urban residents (34.10%) than that in rural residents (13.98%); urban women (39.06%) were higher than rural women (16.13%) and urban men (26.97%) were higher than rural men (12.20%). c) The prevalence of hyperuricemia associated with hypertension which was higher in urban residents (58.06%) than that in rural residents (32.64%); urban women (59.38%) were higher than rural women (35.48%) and urban men (56.18%) were higher than rural men (30.49%). d) The prevalence of hyperuricemia associated with impaired glucose tolerance (IGT) in urban women (28.91%) were lower than that in rural women (45.16%). Conclusion Hypercholesterolemia and hypertension are the most commonly seen cardiovascular risk factors accompanied in patients with hyperuricemia in urban areas, which has obviously higher prevalence than in rural areas. IGT is the most commonly seen cardiovascular risk factors accompanied in patients with hyperuricemia among rural women. But in aspects of hyperuricemia associated with impaired fasting glucose (IFG), hypertriglyceridemia, low high-density fetoprotein cholesterol, abdominal obesity and obesity, there is no difference between urban and rural areas.
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 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 of hypertension and to find the cardiovascular risk factors in the urban residents 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. They were 35-70 years old and had resided in the area for over 2 years. Hypertension questionnaire was used and physical examinations were taken to investigate. The definition of hypertension was determined by the Guidelines of Hypertension Prevention and Control made by National Revision Committee in 2010. Logistic regression model was used to define the risk factors for hypertension. ResultsThe prevalence rate of hypertension was 44.87%, and the standardized prevalence rate was 39.21% (male:41.07%, female:38.20%). The difference of prevalence rate between males and females was not significant (P>0.05). The prevalence rate of hypertension increased significantly with age. By multi-factor logistic regression analysis, age (OR=1.103, P<0.001), serum uric acid (OR=1.003, P=0.001), heart rate (OR=1.014, P=0.027), and waist circumference (OR=1.624, P<0.001) were the risk factors for hypertension. ConclusionThe prevalence rate of hypertension is high in urban communities of Chengdu city, and age, serum uric acid, heart rate, and waist circumference are the risk factors for hypertension.
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 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 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 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.
