This study investigated the updated prevalence of metabolic syndrome among adults in West China and the influence of diet and behaviour on metabolic syndrome.A cross-sectional survey was conducted from 2013-2014, and multi-stage stratified clustering sampling was applied in 12 counties of Sichuan province. Data regarding metabolic syndrome and style risk factors were collected through interviewer-administered questionnaires, and physical measurements were recorded following a standardized protocol. Logistic regression models were used to explore the association between metabolic syndrome and its risk factors.A total of 7,131 adults participated. The prevalence of metabolic syndrome was 16.9% and 23.8% according to the International Diabetes Federation criteria and the consensus definition, respectively. The International Diabetes Federation criteria failed to identify 28.8% of the participants identified by the consensus definition. The odds ratios (ORs) of suffering from Metabolic syndrome in people eating pork every week compared with at lower frequencies, people eating more than 100 g of red meat/day, people with more sedentary behaviour per day, and people consuming at least 20 cigarettes/day were 1.76 (1.09-2.84), 1.28 (1.01- 1.62), 1.03 (0.99-1.07), and 1.46 (1.12-1.92), respectively, according to the consensus definition, and 1.51 (1.09- 2.10), 1.4 (1.14-1.72), 1.07 (1.02-1.13), and 1.5 (1.16-1.94), respectively, based on the International Diabetes Federation criteria.The International Diabetes Federation criteria were less sensitive in identifying metabolic syndrome than the consensus definition. More sedentary behaviour, smoking >=20 cigarettes per day, and a higher frequency of pork intake increased the risk of metabolic syndrome in this study.
Previous studies have shown that there is a geographic variation in the prevalence of stroke, with a lower prevalence of stroke in Sichuan province. And a stroke transition was found during the period of economic development as well. However, as the center of Southwest China, with a greatly developed economy, whether the geographic variation remained with lower burden of stroke in Sichuan province is unknown. Therefore, in this study, we analyzed the secular stroke status in Sichuan province to help explore the potential reasons for geographic disparity. From a cross-sectional study conducted based on 8 national disease surveillance points (DSPs) in Sichuan Province in 2013 the epidemiologic data of stroke were collected. Data of risk factors were obtained from a cross-sectional study based on 12 national DSPs in Sichuan Province in 2013. The results showed that the standardized prevalence, incidence and mortality of stroke in Sichuan province were 338.6/100 000 people (95% CI, 267.8-409.4), 147.1/100 000 person-years (95% CI, 100.6-193.6), and 72.4/100 000 person-years (95% CI, 40.0-104.8), respectively, which were significantly lower than those determined from the contemporary data of China in 2013 . The analysis of the risk factors showed that the weights of contribution of the potential risk factors to stroke was in consistency with those published reports from other areas. In conclusion, the disparity of lower stroke burden in Sichuan than the average China remained, though with the great developments in Sichuan province over all those decades. In addition to traditional modifiable factors, we suggest that unknown or intrinsic differences such as genetic factors might play an important role in geographic disparity, which should be investigated in future studies.
To observe the effect of electroacupuncture (EA) of "Biao-Ben acupoints" (Biao indicates pathogenic factors of disease; Ben refers to body constitution) on renal function, hemorheology and endothelial nitric oxide synthase (eNOS) level in patients with early diabetic kidney disease (DKD), so as to explore its mechanism underlying relieving early DKD.A total of 120 patients with early DKD were selected and randomized into 3 groups: medication, conventional acupoints, and "Biao-Ben"acupoints groups by stratified randomization method, with 40 cases in each group. Patients of the me-dication group were treated by routine symptomatic supportive treatment (gleziquantel tablets or subcutaneous injection of insulin \[for hyperglycemia\], candesartan tablet \[hypertension\], simvastatin tablets \[hyperlipidemia\], etc.).Based on the medication group, patients of the conventional acupoint group were treated by EA of bilateral Feishu (BL13), Weiwanxiashu (EX-B3), Weishu (BL21), Shenshu (BL23), Sanyinjiao (SP6), Taixi (KI3) (main acupoints), etc., and those of the Biao-Ben acupoint group treated by EA of main acupoints Zhongwan (CV12), Fenglong (ST40), Xuehai (SP10) and Taichong (LR3) (Biao acupoints), and Guanyuan (CV4) and Zusanli (ST36) (Ben acupoints). The EA treatment was conducted one daily, 5 days a week for 8 weeks. The urine microprotein level in 24 h was detected using an automatic specific protein analyzer, followed by calcula-ting the urine albumin excretion rate (UAER). The serum creatinine (Scr), urea nitrogen (BUN) and cystatin (CysC) contents were detected by using an automatic biochemical analyzer, and the whole blood low-cut viscosity (ηbL), whole blood mid-cut viscosity (ηbM), whole blood high-cut viscosity (ηbH), plasma viscosity (ηp) and fibrinogen (FIB) levels were detected using an automatic hemorheology tester, and the serum eNOS and nitric oxide (NO) levels assayed using enzyme linked immunosorbent assay. The total clinical effective rates were compared and the adverse reactions of the treatment were recorded.Compared with the values before the treatment in each group, the levels of UAER, Scr, BUN, CysC, ηbL, ηbM, ηbH, ηp and FIB were all significantly decreased (P<0.01), while serum eNOS and NO levels significantly increased in the three groups after the treatment (P<0.01). Compared with the medication group, the levels of UAER, Scr, BUN, CysC, ηbL, ηbM, ηbH, ηp and FIB were notably lower (P<0.01, P<0.05), and serum eNOS and NO contents obviously higher in both the conventional acupoint and "Biao-Ben" acupoint groups (P<0.01). Comparison between the two EA groups showed that the levels of UAER, BUN, ηbL, ηbM, ηbH and ηp were lower (P<0.05), whereas the serum eNOS and NO contents were considerably higher (P<0.05) in the "Biao-Ben" acupoint group than in the conventional acupoint group. After the treatment, the total clinical effective rate of the "Biao-Ben" acupoint group was 89.74%(35/39), being significantly higher than those of both the conventional acupoint group (71.05%, 27/38,P<0.05) and medication group (64.10%, 25/39, P<0.05).EA of "Biao-Ben" acupoints can improve renal function and reduce microcirculation disorders in patients with early DKD, which may be related to its function in up-regulating the levels of serum eNOS and NO.目的：观察“标本配穴”电针疗法对早期糖尿病肾病(DKD)患者肾功能、血液流变学和内皮型一氧化氮合酶(eNOS)水平的影响，探讨“标本配穴”电针对早期DKD的保护作用及机制。方法：选取120例早期DKD患者，随机分为西药组、常规组、标本配穴组，每组40例。西药组予常规控制血糖、血压、血脂治疗；在西药组治疗的基础上，标本配穴组根据“标本配穴”法电针“标”穴中脘、丰隆、血海、太冲及“本”穴关元、足三里，常规组电针双侧肺俞、胃脘下俞、胃俞、肾俞、三阴交、太溪。各组均治疗1次/d，5 d/周，共治疗8周。分别于治疗前后采用全自动特异性蛋白质分析仪检测各组患者24 h尿微量白蛋白排泄率(UAER)；全自动生化分析仪检测血清肌酐(Scr)、尿素氮(BUN)、胱抑素(CysC)含量；全自动血流变测试仪检测全血低切黏度(ηbL)、全血中切黏度(ηbM)、全血高切黏度(ηbH)、血浆黏度(ηp)和纤维蛋白原(FIB)水平；酶联免疫吸附试验测定血清eNOS和一氧化氮(NO)水平。比较各组治疗的总有效率并观察其不良反应。结果：与本组治疗前比较，3组患者治疗后UAER及血清Scr、BUN、CysC，ηbL、ηbM、ηbH、ηp、FIB水平均显著下降(P<0.01)，血清eNOS、NO含量显著升高(P<0.01)。治疗后与西药组比较，常规组和标本配穴组UAER及血清Scr、BUN、CysC，ηbL、ηbM、ηbH、ηp、FIB水平降低(P<0.01，P<0.05)，血清eNOS、NO含量显著升高(P<0.01)；与常规组比较，标本配穴组UAER及血清BUN，ηbL、ηbM、ηbH、ηp降低(P<0.05)，血清eNOS、NO水平升高(P<0.05)。标本配穴组总有效率为89.74%(35/39)，常规组为71.05%(27/38)，西药组为64.10%(25/39)，标本配穴组明显高于常规组和西药组(P<0.05)。结论：“标本配穴”电针能改善早期DKD患者肾脏功能，减轻微循环障碍，其机制可能与上调血清eNOS和NO水平有关。.
Regarding the needling manipulation, Chifeng Yingyuan, there are different descriptions in ancient medical literature and the current teaching materials or clinical reports, especially for the understanding recorded in Jinzhenfu Poem of Golden Needle). In the current teaching materials and clinical reports, it is described that the needle is inserted deeply at first, and then shallowly; afterward, the needle tip is pushed to the middle layer and manipulated with lifting, thrusting and rotating technique, combined with twisting and flying method. After analyzing the original description in the book and the feasibility of function and operation, the authors introduced their recognition on its manipulation and techniques in this article. This manipulation should be: the needle is inserted to the middle layer, afterward, the needle body is pulled and tilted toward each of the four directions, on this basis, then twisting and flying method is applied.
Abstract Background: To compare the epidemiological characteristics of Sichuan Province, other provinces in China and the world epidemic trends by analyzing the prevalence and length of epidemic time. in order to provide a basis for responding to imported cases abroad and to formulate prevention and control strategies in areas that are still rapidly circulating.Methods: The number of confirmed cases, daily growth, incidence and the length of time from the first reported case to the end of local case(non-overseas imported cases) were compared by spatial and temporal (geographical, temporal) classification. Visualizing the development and changes of epidemic situation by layer through maps.Results: In the first wave, total of 539 cases were reported in Sichuan Province, with the incidence rate of 0.6462 / 100,000. The closer to Hubei, the heavier the epidemic. The peak of Sichuan Province came earlier and the value was lower. Eight weeks after Wuhan lockdown, all became better. The longest epidemic length in city level of China was 53 days, median 23 days. It was released quickly in the 1st month, and accelerated in the 2ed month (three times of 1st month). Most countries outside China began to rise rapidly 4 weeks after their first case. Some European countries was earlier than USA. Germany, Spain, Italy, and China cost 28, 29, 34, and 18 days to reached the peak of daily increment, after their daily increase up to 20 cases. Countries in African Region and South-East Asia Region were at the early stage, in Eastern Mediterranean Region and Region of the Americas were at rapid growth phase,in European presented an inflection point or at a plateau period but falling slowly.Conclusions: Adopting appropriate isolation and control measures is necessary to actively respond to the epidemic situation. If effective measures were implemented at the 8 key weeks, the peak value of the confirmed cases will be lower and decrease quickly. Some countries with improved epidemic situations also need to develop a continuous "local strategy at entry checkpoints" to respond to a possible second local epidemic.
This study explored the prevalence of and individual influencing factors for metabolic syndrome (MS) as well as associated socioeconomic factors and regional aggregation.Four cross-sectional surveys were analysed for trends in MS and associations with socioeconomic and individual factors through multilevel logistic regression analyses. The risk associated with nutrient intake was also assessed through a dietary survey in 2015.From 2010 to 2018, 8-15 counties/districts of West China were included.A total of 28 274 adults were included in the prevalence analysis. A total of 23 708 adults were used to analyse the related factors.The overall prevalence of MS ranged from 21.4% to 27.8% over the 8 years, remaining basically stable within the 95% CI. Our study found that the urbanisation rate and hospital beds per 1000 people were positively associated with MS, and the number of doctors in healthcare institutions per 1000 persons was negatively associated with MS. The ORs for females, people with college education and higher and unmarried or single people were 1.49, 0.67 and 0.51, respectively (p<0.05). The ORs of people who smoked at least 20 cigarettes/day, ate more than 100 g of red meat/day, consumed fruit or vegetable juice and drank carbonated soft drinks less than weekly were 1.10, 1.16, 1.19-1.27 and 0.81-0.84, respectively. The ORs rose with increasing sedentary time and decreased with higher physical activity.The high burden of MS, unreasonable proportions of energy and micronutrient intake and low percentage of high levels of physical activity were the major challenges to public health in western China. Improving the human resources component of medical services, such as the number of doctors, increasing the availability of public sports facilities and E-health tools and improving individual dietary quality and education might help prevent MS.
Abstract Background: The COVID-19 spread worldwide quickly. Exploring the epidemiological characteristics could provide a basis for responding to imported cases abroad and to formulate prevention and control strategies in areas where COVID-19 is still spreading rapidly. Methods: The number of confirmed cases, daily growth, incidence and length of time from the first reported case to the end of the local cases (i.e., non-overseas imported cases) were compared by spatial (geographical) and temporal classification and visualization of the development and changes of the epidemic situation by layers through maps. Results: In the first wave, a total of 539 cases were reported in Sichuan, with an incidence rate of 0.6462/100,000. The closer to Hubei the population centres were, the more pronounced the epidemic was. The peak in Sichuan Province occurred in the second week. Eight weeks after the Wuhan lockdown, the health crisis had eased. The longest epidemic length at the city level in China (except Wuhan, Taiwan, and Hong Kong) was 53 days, with a median of 23 days. Spatial autocorrelation analysis of China showed positive spatial correlation (Moran's Index >0, p<0.05). Most countries outside China began to experience a rapid rise in infection rates 4 weeks after their first case. Some European countries experienced that rise earlier than the USA. The pandemic in Germany, Spain, Italy, and China took 28, 29, 34, and 18 days, respectively, to reach the peak of daily infections, after their daily increase of up to 20 cases. During this time, countries in the African region and Southeast Asian region were at an early stage of infections, those in the Eastern Mediterranean region and region of the Americas were in a rapid growth phase. Conclusions: After the closure of the outbreak city, appropriate isolation and control measures in the next 8 weeks were key to control the outbreak, which reduced the peak value and length of the outbreak. Some countries with improved epidemic situations need to develop a continuous "local strategy at entry checkpoints" to to fend off imported COVID-19.
