Objective: To explore the association between the accumulation of metabolic syndrome (MS) components and abnormal brachial ankle pulse wave velocity (baPWV), and to investigate the effect of accumulation of abnormal metabolic components on abnormal baPWV among adult individuals undergoing routine health examination. Methods: It's a cross-sectional study. Data from 9 201 stratified sampled subjects, aged between 25 to 75 years old, who took part in the annual health checkups in 11 cities of Zhejiang Province from January to December 2016, were analyzed. Blood pressure(BP), fasting plasma glucose(FPG), waist circumference(WC), triglyceride(TG), high-density lipoprotein cholesterols(HDL-C) were defined as MS components. The baPWV was measured by VP-1000 (BP-203RPE Ⅲ) and ΔbaPWV (measured baPWV-reference baPWV/reference baPWV) ×100 (%)> 10% was defined as abnormal. The relationship between MS components and ΔbaPWV was analyzed by linear regression, and impact of accumulation of MS components on ΔbaPWV was analyzed by logistic regression, and the ΔbaPWV in subjects with different levels of MS components were analyzed by analysis of variance. Results: (1) The linear regression analysis demonstrated a positive correlation between ΔbaPWV and MS components including systolic blood pressure, diastolic blood pressure, WC, FPG, TG, while ΔbaPWV was negatively correlated with HDL-C. The β values were 0.518, 0.616, 0.208, 2.778, 1.862, -1.339, respectively (all P<0.001), indicating a strong association between ΔbaPWV and systolic blood pressure, diastolic blood pressure, and FPG. (2) The logistic regression analysis showed that the proportion of abnormal ΔbaPWV was 2.595 times higher in MS individuals than in non-MS individuals (P<0.001). Abnormal ΔbaPWV increased in proportion with increase in numbers of the metabolic components (OR=1.913, 2.884, 3.833, 6.161, 11.176 in individuals with 1,2,3,4,5 metabolic components, respectively, all P<0.001). (3) The logistic analysis suggested that each component of MS could affect baPWV,and OR was 4.68, 2.45 for systolic blood pressure and/or diastolic blood pressure and FPG. All combinations of 2 components of MS also significantly affected baPWV,and OR value was the highest (5.104(95%CI 4.281-6.085), P<0.001) for FPG+BP. All combinations of 3 components of MS significantly affected baPWV,and OR value was the highest(5.385(95%CI 4.245-6.831), P<0.001) for BP+FPG+TG. All combinations of 4 components of MS affected baPWV,and OR value was the highest (6.519(95%CI 4.731-8.984), P<0.001) for BP+FPG+WC+TG. (4) Finally, every component of MS was divided into 3 levels, their impact on abnormal ΔbaPWV was analyzed. Prevalence of abnormal ΔbaPWV significantly increased with the increasing levels of the metabolic components expect for HDL-C, the F values were 1 224.66, 832.89, 192.72, 112.79 and 56.22, respectively (all P<0.001), indicating that higher levels of metabolic components significantly affected the ΔbaPWV. Conclusions MS and accumulation of abnormal MS components are closely related with abnormal ΔbaPWV, and the combination of BP and FPG have the greatest impact on the abnormal ΔbaPWV. Analysis on the accumulation of MS components might serve as an early indicator of arteriosclerosis.

The authors described the attempt of general practice in hierarchical medical system aided by the medical service partnership model.This reform has achieved an effective and efficient hierarchical medical system for chronic diseases within a medical alliance, overcoming the existing hierarchical medical system centering on a hospital.Other merits of the reform include a general practice guidance pattern between general hospitals and community hospitals and enhanced general practitioner competence in communities,effectively encouraging general practice progress.

Objective To observe the clinic effects and safety of thoracic dorsal root ganglion(DRG) pulsed radiofrequency in treating post-thoracotomy pain syndrome(PTPS). Methods 47 PTPS patients were treated with thoracic DRG pulsed radiofrequency. VAS, Oxycodone dosage, medicine side effects before and after operation were recorded. Results The VAS before operation and 1 d, 15 d, 1 m, 3 m, 6 m, 12 m after operation were 6. 3 ±2. 4, 4. 1 ±1. 8, 3. 2 ±1. 3, 2. 5 ±1. 5, 2. 1 ±0. 9, 2. 0 ±0. 8 and 2. 2 ±1. 1 respectively. The oxycodone dosage were (28. 5 ±10. 2)mg, (12. 3 ±5. 7)mg, (8. 3 ±3. 8)mg, (7. 6 ± 3. 1) mg, (7. 0 ± 3. 4) mg, (6. 6 ± 2. 7) mg and (7. 2 ± 3. 2) mg respectively. The difference was significant compared with the preoperative (P＜0. 05). No serious complications occurred. Conclusion Thoracic DRG pulsed radiofrequency was a safe and effective method in treating PTPS.
