Objective To investigate the prevalence of chronic non-communicable diseases among farmers,land less peasants and urban population in a certain area of Anhui Province,to explore the relationship between the lifestyles of landless peasants and their chronic non-communicable diseases.Methods A total of 761 valid questionnaires were collected by cross-sectional epidemiological study,including 119 farmers,259 landless peasants and 383 urban groups.The enumeration data was analyzed by x2 test and the measurement data analyzed by variance.The risk of chronic non-communicable diseases in each group was analyzed by Logistic regressions.Results General demographic characteristics showed that there were differences in three groups of people in the respects of drinking,eating habits and physical activity and other lifestyles (all P < 0.05).Logistic regression analysis showed that the onset risk of hypertension and overweight obesity in the famer group and the landless peasant group was lower than that in the urban group,but higher than that in the peasant group.After adjusting for confounding factors,the prevalence of hypertension in the farmer group (OR =0.20,95% CI:0.12-0.33) and the lost land group (OR =0.65,95% CI:0.44-0.95) was lower than that in the urban group,the overweight obesity in the farmer group (OR =0.44,95% CI:0.27-0.74) and the lost land group(OR =0.67,95% CI:0.47-0.96) was lower than that in the urban group.The incidence of atherosclerosis in the farmer group (OR =2.48,95 % CI:1.45-4.23) and the lost land group(OR =2.00,95% CI:1.33-3.02) was higher than that in the urban group.Conclusions The living style of landless peasants is different from those of rural group and urban group,and the incidence of hypertension and overweight obesity is higher than that of farmers.We should take interventions against chronic non-communicable diseases in landless peasants.

Objective:To compare the clinical effect of Ilizarov frame and unilateral frame in the treatment of tibial segmental bone defect combined with soft tissue defect by open bone transport.Methods:A retrospective case-control study was conducted to analyze the clinical data of 32 patients with tibial segmental bone defect and soft tissue defect-up who underwent open bone transport technique in Tianjin Hospital from August 2008 to August 2016 and obtained complete followed-up. There were 22 males and 10 females, aged 22-64 years (mean, 36.8 years). Nineteen patients in the Ilizarov group showed the mean bone defect length of 7.9 cm and mean soft tissue defect area of 41.4 cm 2. Thirteen patients in the unilateral group showed the mean bone defect length of 7.8 cm and the mean soft tissue defect area of 39.2 cm 2. The results of fracture healing, wound healing time, radiological consolidation index, external fixation index, Association for the Study and Application of the Method of Ilizarov (ASAMI) bone and lower-limb function score and incidence of complications were compared between the groups. Results:All patients were followed up for 24 to 60 months [(32.6±1.3)months]. Bone healing was achieved in all patients. The wound healing time was (2.7±2.3)days in Ilizarov group and (2.4±1.8)days in unilateral group ( P>0.05). The consolidation index was (43.4±8.7)d/cm in Ilizarov group and (45.8±10.3)d/cm in unilateral group ( P>0.05). The external fixation index was (52.6±8.9)d/cm in Ilizarov group and (58.7±12.9)d/cm in unilateral group ( P<0.05). The results of ASAMI bone score was excellent in 10 patients, good in 6, fair in 2 and poor in 1 in Ilizarov group, with the excellent rate of 84%; and excellent in 6 patients, good in 4, fair in 2, and poor in 1 in unilateral group, with the excellent rate of 77%, with insignificant difference between two groups ( P>0.05). The results of ASAMI lower-limb function score was excellent in 8 patients, good in 7, fair in 3, poor in 1 in Ilizarov group, with the excellent rate of 79%; and excellent in 6, good in 3, fair in 3, poor in 1 in unilateral group, with the excellent rate of 69%, with insignificant difference between the two groups ( P>0.05). Incidence of axial deviation was zero in Ilizarov group versus 23% in unilateral group ( P<0.05). After operation, Ilizarov group had refracture in 1 patient and pin site infection in 5, and unilateral group had refracture in 1 patient and pin site infection in 1, showing no significant difference between the two groups ( P>0.05). Conclusions:Tibial segmental bone defect with soft tissue defect can be effectively treated by open bone transport with Ilizarov and unilateral frame. Ilizarov frame has better biomechanical properties and is more convenient for correction of poor postoperative axial alignment.

Objective:To investigate the accuracy and postoperative efficacy of fluoroscopy and CT in measuring the mounting parameters of Taylor Spatial Frame.Methods:Data of patients with peripheral knee deformities who were treated by Taylor Spatial Frame from June 2006 to December 2017 were retrospectively analyzed. According to different measurement methods of mounting parameters, they were divided into fluoroscopy group (mounting parameters were obtained by intraoperative fluoroscopy) and CT group (mounting parameters were obtained by postoperative CT). There were 33 patients (35 segments) in the fluoroscopy group, 23 males (23 segments) and 10 females (12 segments), with an average age of 36.4±11.6 years old. In CT group, there were 30 patients, 19 males and 11 females, with an average age of 36.9±13.8 years. There were 22 cases (24 segments) of high tibial osteotomy, 5 cases (5 segments) of distal femur osteotomy, and 6 cases (6 segments) of both distal femur and high tibial osteotomy. Operation time, external fixation time, the number of electronic prescription and deformity correction time, mechanical axis deviation (MAD), medial proximal tibia angle (MPTA), mechanical lateral distal femoral angle (mLDFA), range of motion (ROM) andhospital for special surgery (HSS) knee functional scores were compared between the two groups.Results:All the 63 patients were followed up for 21.9 months (range, 12-60 months). In fluoroscopy group, operating time was 100.9±9.1 min, electronic prescription number 1.4±0.6, and deformity correction time was 19.4±3.6 days. In CT group, operating time was 79.2±10.8 min, electronic prescription number 1.2±0.4, and deformity correction time was 16.0±4.4 days. The difference of the above indexes between the two groups was statistically significant ( t=8.803, 2.042, 3.440, all P < 0.05). In the fluoroscopy group, the external fixation time was 4.8±0.9 months; MAD was 4.3±2.1 mm; MPTA was 88.5°±1.9°; mLDFA was knee 89.2°; ROM was 122.4°±3.9° and HSS score was 90.0±3.6. In CT group, the external fixation time was 4.6±0.9 months; MAD was 4.0±1.9 mm; MPTA was 87.8°±1.7°; mLDFA was knee 88.6°; ROM was 122.7°±3.4° and HSS score was 91.1±2.9. There was no statistically significant difference in the above indexes between the two groups (all P >0.05). In the fluoroscopy group, 22 segmental deformities were corrected by one electronic prescription, and 13 segmental deformities were corrected by two or more electronic prescriptions. In CT group, 25 segmental deformities were corrected by one electronic prescription, and 5 segmental deformities were corrected by two electronic prescriptions. There was no incision infection and no neurovascular injury in the two groups. Conclusion:Both fluoroscopy and CT scan can obtain the mounting parameters of the Taylor Spatial Frame, and the results of correction of the peripheral deformities of the knee joint are satisfactory. However, CT measurement of the mounting parameters is more accurate which could achieve shorter operation time, and less times of electronic prescriptions.
