Abstract
BACKGROUND With a large population of internal migrants from all over the world, China has the largest number of internal floating migrants, and most of them (up to 169 million in 2016) are rural-to-urban migrants. Those migrants have difficulty accessing essential health care services because of Hukou, leading to disparities in health needs and utilization between rural-to-urban migrants and residents. To compare the needs and utilization of health services between urban residents and rural-to-urban migrants in China from 2012 to 2016. METHOD We used longitudinal data from the Chinese Labor Dynamic Survey (CLDS) with three waves in 2012, 2014 and 2016. Descriptive analysis was employed to show self-reported illnesses and health services utilization among locals and migrants in the most recent 2 weeks in China. Chi-square tests and log binomial regression models were constructed to explore factors influencing health care needs and utilization. RESULT A total of 19.97% of respondents were rural-to-urban migrants, with an upward trend from 2012 to 2016. Rural-to-urban migrants (11.99%) had higher needs for health services than urban residents (10.47%) in general, while urban residents and migrants had no differences in needs in 2012. Besides, there was no difference in the utilization of health services between residents and migrants in 2012, 2014 or 2016. In addition, increased age, male sex, poor medical insurance coverage and dissatisfaction with income were found to have negative effects on health care needs. CONCLUSION This study has shown that the rural-to-urban migrants had higher health care needs but the same health care utilization compared with urban residents in China. Health policies focusing on equitable health outcomes should pay more attention to rural-to-urban migrants in China's health care system reform.

Effects of storage temperature and combined microbial inoculants on fermentation end products and microbial populations of Italian ryegrass (Lolium multiflorum Lam.) silage. J Appl Microbiol 2018; 125:1682-1691. [PMID: 30133082 DOI: 10.1111/jam.14083] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2018] [Revised: 07/29/2018] [Accepted: 08/19/2018] [Indexed: 12/24/2022]
Abstract
AIMS To examine five lactic acid bacteria (LAB) strains (LCG9, LTG7, I5, TG1 and LI3) isolated from the Tibetan Plateau, and evaluate their combined effects on the silage quality of Italian ryegrass (Lolium multiflorum Lam.) at three temperatures (10, 15 and 25°C). METHODS AND RESULTS The isolated strains were evaluated by morphological, physiological and biochemical tests. Six combined inoculants LCG9+LI3, LCG9+I5, LCG9+TG1, LTG7+LI3, LTG7+I5 and LTG7+TG1 were added to Italian ryegrass for ensiling 30 days in laboratory silos (1L) at various temperatures, respectively. All the isolates could grow normally at 5-20°C, pH 3·5-7·0 and NaCl (3·0, 6·5%). Compared to three corresponding controls, all the inoculants improved the silage quality of Italian ryegrass at different temperatures, indicated by markedly (P < 0·05) higher lactic acid (LA) contents and ratios of lactic acid/acetic acid (LA/AA), and lower pH and ammonia nitrogen (NH3 -N) contents and undesirable micro-organism counts. At 10°C, LTG7+LI3, I5 or TG1 inoculants performed superior to LCG9+LI3, I5 or TG1 inoculants, evidenced by distinctly (P < 0·05) higher LA contents and ratios of LA/AA, and lower pH and NH3 -N contents. LTG7+LI3 or TG1 silages had obviously (P < 0·05) higher LAB counts than LTG7+I5 silage at 10°C. CONCLUSIONS Therefore, the combined inoculants LTG7 + LI3 or TG1 are recommended as starter cultures for Italian ryegrass silage at low temperatures. SIGNIFICANCE AND IMPACT OF THE STUDY Temperature is a key factor affecting ensilage. In cold regions, low temperature could be an adverse environmental condition during ensiling. However, few studies have focused on improving silage quality at low temperatures. Moreover, analysis of effects of combined LAB strains with their physiological and biochemical characteristics help us use combined LAB inoculants to realize the fermentation optimization.

Abstract
BACKGROUND AND AIMS It is expected that older adults with metabolic abnormalities may benefit from weight loss; however, data on this population are limited. Our study was to assess the effect of obesity and weight change on mortality risk in older adults with metabolic abnormalities. METHODS AND RESULTS A total of 3649 Chinese older adults aged 60-90 years with metabolic abnormalities were included between 2000 and 2014. Weight change between two health checkup periods was calculated. During a median follow-up period of 37 months, 503 all-cause mortality and 235 cardiovascular disease mortality occurred. Death rate was the lowest in overweight participants and in the participants with weight stability. After adjustment for covariates, hazard ratios (95% confidence intervals) of overweight participants for all-cause mortality and cardiovascular mortality were 0.71 (0.59, 0.86) and 0.72 (0.55, 0.95), respectively, whereas obesity was not significantly associated with mortality risk. Furthermore, relative to weight stability, risks of mortality significantly increased with the increase in weight loss or weight gain, except small weight gain. These associations were unchanged when the participants were stratified by baseline covariates and even when several definitions of weight change were considered. CONCLUSIONS Overweight was associated with less mortality risk, and obesity was not associated with mortality risk in older adults with metabolic abnormalities. Mortality risk increased with the increase in weight loss or weight gain, regardless of body weight levels at the baseline. These findings suggest that maintaining a stable weight may be the best choice in older adults with metabolic abnormalities.

Abstract
Objective: To understand the status, attitude and related risk factors on smoking among 18-65 years old patients with hypertension, diabetes, dyslipidemia, chronic obstructive pulmonary disease (COPD) or asthma in Beijing. Methods: Data was gathered from the 2014 Beijing Non-communicable and Chronic Disease Surveillance Program. Multiple classified cluster sampling method was used and 19 815 participants aged 18-65 were sampled from 16 districts in Beijing. Results: Among all the 18 405 participants, male hypertensive patients showed a higher rate on current smoking than the other groups (χ(2)=17.695, P<0.001). Male patients with dyslipidemia had higher current smoking rate than the other groups (χ(2)=39.292, P<0.001). However, female patients with COPD or with asthma showed higher rate on current smoking than the other groups (χ(2)=6.276, P=0.012), (χ(2)=8.245, P=0.004). Among the smokers, hypertensive patients presented lower rate (χ(2)=20.487, P<0.001) on intention of smoking concession, than the other groups. Patients with COPD showed greater intention in quitting smoking (χ(2)=6.085, P=0.048), than the other groups. Male patients with diabetes (χ(2)=9.219, P=0.010) or dyslipidemia (χ(2)=13.513, P=0.001) who had stopped smoking tobacco appeared having higher rates in keeping the current status. Results from logistic regression analyses showed that smoking was the risk factor for hypertension (OR=1.17), dyslipidemia (OR=1.25), COPD (OR=1.78), and asthma (OR=1.57). Conclusions: Patients with certain kinds of chronic diseases showed higher rate of current smoking and lower rate of quitting. Cigarette consumption appeared an important risk factor for patients with hypertension, dyslipidemia, COPD, or asthma in Beijing.

Abstract
INTRODUCTION Triceps motor branch transfer has been used for more than ten years to restore deltoid function after axillary nerve injury. However, there have been few reports of the outcome of this procedure in isolated axillary nerve injury. HYPOTHESIS Triceps motor branch transfer could be an effective method to restore deltoid function for patients with isolated axillary nerve injury. MATERIALS AND METHODS Nine patients who underwent triceps motor branch transfer for treatment of isolated axillary nerve injury were followed up for at least 22 months. Shoulder abduction was assessed for all patients. The DASH outcome questionnaire was completed by every patient. Electrophysiological study was performed on 7 patients. RESULTS All patients regained≥90° (mean, 137°) shoulder abduction. Mean DASH score decreased from 35.2 before surgery to 13.1 at the last follow-up. There was no noticeable weakness of elbow extension in any patient. DISCUSSION Triceps motor branch transfer provided good results and may be a feasible alternative to nerve grafting for the treatment of complete isolated axillary nerve injury. TYPE OF STUDY IV, retrospective cohort study.

Abstract
Quantitative information is scarce in current obesity medication guidelines, and they do not clearly reflect the differences in the efficacy characteristics among various drugs. This study quantitatively assessed the efficacy characteristics of five FDA-approved long-term weight loss drugs. Potentially eligible studies were obtained from public databases. Using the differences in the weight change from baseline between the drug group and the corresponding placebo group as the major indicator of efficacy, a time-effect model was established, and crucial pharmacodynamic parameters, such as the maximal efficacy, drug onset time and rate of body weight regain after the maximal efficacy point, were used to reflect the differences in efficacy among the five drugs. Finally, 50 reports (involving 43,443 participants) were included. After deducting the placebo effects, the maximal efficacies (95% CI) of orlistat (120 mg), lorcaserin, naltrexone-bupropion, phentermine-topiramate (PT, 7.5/46 mg) and liraglutide were -2.94 (-5.82, -1.27), -3.06 (-4.39, -1.71), -6.15 (-9.78, -3.25), -7.45 (-9.76, -3.88) and -5.50 (-10.62, -2.97) kg at weeks 60, 54, 67, 59 and 65 respectively, and their rates of body weight regain were 0.51, 0.48, 0.91, 1.27and 0.43 kg per year respectively. The 1-year dropout rates of orlistat, lorcaserin, naltrexone-bupropion, PT and liraglutide were 29.0, 40.9, 49.1, 34.9 and 24.3% respectively. In addition, a significant dose-effect correlation was observed for orlistat and PT. This study provides valid quantitative information for medication guidelines.

Abstract
The discovery of two-dimensional (2D) materials comes at a time when computational methods are mature and can predict novel 2D materials, characterize their properties, and guide the design of 2D materials for applications. This article reviews the recent progress in computational approaches for 2D materials research. We discuss the computational techniques and provide an overview of the ongoing research in the field. We begin with an overview of known 2D materials, common computational methods, and available cyber infrastructures. We then move onto the discovery of novel 2D materials, discussing the stability criteria for 2D materials, computational methods for structure prediction, and interactions of monolayers with electrochemical and gaseous environments. Next, we describe the computational characterization of the 2D materials' electronic, optical, magnetic, and superconducting properties and the response of the properties under applied mechanical strain and electrical fields. From there, we move on to discuss the structure and properties of defects in 2D materials, and describe methods for 2D materials device simulations. We conclude by providing an outlook on the needs and challenges for future developments in the field of computational research for 2D materials.

Abstract
Objective: To understand the prevalence of hypercholesterolemia and related risk factors in residents aged 18-65 years in Beijing and provide scientific evidence for the prevention and control of hypercholesterolemia. Methods: The data were collected from Beijing Non-communicable and Chronic Disease Survey and stratified cluster sampling method was used to select study subjects, and questionnaire investigation, physical measurement and laboratory examination were conducted to collect information. Results: The prevalence of hypercholesterolemia and borderline hypercholesterolemia was 6.26% and 21.34% respectively in 17 662 residents surveyed, the average total cholesterol level was (4.69±0.95) mmol/L. The prevalence of hypercholesterolemia was 6.33% in men and 6.20% in women, the difference was not significant (Z=1.64, P=0.10). The prevalence was higher inurban area than in suburb (6.73% vs. 5.59%; Z=-7.27, P<0.01). The prevalence of hypercholesterolemia increased with age (trend χ(2)=308.85, P<0.01). The trend was observed in men (trend χ(2)=81.65, P<0.01), in women (trend χ(2)=318.04, P<0.01), in urban area (trend χ(2)=201.77, P<0.01) and in suburb (trend χ(2)=114.65, P<0.01). Multiple logistic regression showed age, being female (OR=1.23, 95%CI: 1.04-1.45), overweight (OR=1.56, 95%CI: 1.34-1.81), obesity (OR=1.82, 95%CI: 1.54-2.16), smoking (OR=1.24, 95%CI: 1.03-1.50), alcohol use (OR=1.40, 95%CI: 1.12-1.75), beef and mutton intake >1 time per week (OR=1.19, 95%CI: 1.02-1.39) were risk factors. Conclusion: The prevalence of hypercholesterolemia in Beijing was lower than national level, and age, gender, location, BMI, smoking, alcohol use, beef and mutton intake were main influencing factors.

Abstract
AIM Prostaglandin E2 mediates sympathoexcitation in chronic heart failure (CHF) through EP3 receptors (PTGER3) in the paraventricular nucleus (PVN). The aim of this study was to investigate the role of c-Jun N-terminal kinase (JNK) in expressional regulation of gamma-aminobutyric acid signalling in PVN in CHF rats. METHODS Chronic heart failure was induced by left coronary ligation in Wistar rats. Renal sympathetic nerve discharge (RSND) and mean arterial pressure (MAP) responses to the PVN infusion were determined in anaesthetized rats. Osmotic minipumps were used for chronic PVN infusion. PTGER3 expression was examined with immunofluorescence staining, quantitative real-time PCR and Western blot. RESULTS Chronic heart failure rats had increased JNK activation and decreased glutamate decarboxylase 1 (GAD1) and GABAA receptor alpha 1 subunit (GABRA1) expression in the PVN. PVN infusion of the PTGER3 agonist SC-46275 caused sympathoexcitation in sham-operated control (Sham) rats and increased it further in CHF. The PTGER3 antagonist L798106 reduced sympathoexcitation and cardiac dysfunction in CHF. PVN infusion of EP1 receptor antagonist SC-19220, EP2 receptor antagonist AH6809 or EP4 receptor antagonist L-161982 had no effect on sympathoexcitation. The JNK inhibitor SP600125 normalized sympathoexcitation and GAD1 and GABRA1 expression in PVN in CHF rats. Both the p44/42 and p38 mitogen-activated protein kinase inhibitors PD98059 and SB203580 could not prevent the downregulation of GAD1 and GABRA1 expression in PVN in CHF. PTGER3 agonist activated JNK but downregulated GAD1 and GABRA1 expression in NG108 neuronal cells. CONCLUSION Prostaglandin signalling through upregulated PTGER3 activates JNK which reduces GAD1 and GABRA1 expression in the PVN, and contributes to sympathoexcitation in CHF.
