Abstract
PURPOSE New strategies are needed for prevention and treatment of chronic lymphocytic thyroiditis (CLT). This study aimed to assess whether combination of levothyroxine treatment and selenium (Se) supplementation results in improved therapeutic effects in CLT compared with levothyroxine monotherapy. METHODS An open-label, randomized controlled study was performed in 60 CLT patients assigned to two groups. Levothyroxine group (LT) patients (n = 24) received levothyroxine alone for 3 months; meanwhile, the combination (LTSS) group (n = 36) was administered levothyroxine with selenium yeast capsule. Blood selenium concentrations, anti-thyroid peroxidase (TPO) and anti-thyroglobulin (Tg) antibody levels, and inflammatory cytokine amounts were compared between both groups before and after treatment. RESULTS At baseline, similar values were obtained in both groups for all the parameters assessed (p > 0.05). After treatment, significantly increased blood selenium levels (µg/L) [90.05 (80.69, 107.76) vs. 39.64 (29.42, 51.10), p < 0.001] and decreased anti-TPO antibody (23.63 ± 9.31 vs. 32.00 ± 10.41%, p = 0.002), anti-Tg antibody (35.84 ± 15.21 vs. 45.47 ± 14.24%, p = 0.015) and IL-2 amounts (pg/mL) [159.29 (124.54, 189.70) vs. 226.48 (190.74, 266.56), p < 0.001] were observed in the LTSS group compared with the LT group post-treatment; meanwhile, similar IL-10 concentrations [23.14 (21.65, 28.56) pg/mL vs. 24.68 (21.71, 29.67) pg/mL] were obtained in both groups. Subgroup analysis of patients with hypothyroidism showed the same trend observed in the whole population; in patients with normal thyroid function, only Se and IL-2 amounts differed between the two treatment groups. Correlation analysis of of the indexes: in HT patients, the basal serum selenium concentration was positively correlated with TT4 (r = 0.294, p < 0.05), significantly negatively correlated with TSH (r = -0.343, p < 0.01), and had no significant correlation with TT3 (p > 0.05). CONCLUSIONS These findings indicated that levothyroxine and selenium combination results in improved therapeutic effects than the levothyroxine monotherapy in preventing CLT progression.

Abstract
Objective: To assess the dietary intake status of Chinese lactating women during the first month postpartum. Methods: Data were extracted from Chinese National Nutrition and Health Surveillance, children aged 0-5 years and lactating women (2013). A total of 55 counties from 30 provinces in China (excluding the Tibet Autonomous Region) were selected using a multi-stage stratified cluster randomization sampling method. A group of 3 623 lactating women, at 1-6 months after delivery, were investigated in the study. The semi-quantitative food frequency questionnaire (FFQ) was used to collect information on frequencies and amounts of food consumed. Differences in food consumption rates and dietary intake in lactating women having different characteristics were analyzed and compared. Results: To eliminate abnormal values, 3 300 lactating women were included in the study. During the first month postpartum, food types with higher consumption rates were animal products (98.2%, 3 239) and vegetables (90.7%, 2 987), in addition to cereals (100%) and liquids (100%). The consumption rate of fruits was 67.4% (2 222) and the lowest consumption rate was for dairy products (38.3%, 1 262). The median intake of cereals, vegetables, fruits and animal products were 247.8, 150.0, 40.0 and 178.6 g/d, respectively. The daily median intake of dairy products and soybean/nut products was 0.0 g/d. Overall, the lactating women consumed 895.7 ml/d liquids. About 49.3% (1 627) of the subjects consumed less than the recommended intake for animal products in Chinese Dietary Guideline (2016). More than 50% of the lactating women consumed less than the recommended intakes for the other types of food, especially dairy, soybean/nut and liquids. The consumption rates for dairy products were 26.9%, 29.4%, 31.8% and 33.8% and those for soybean/nut products were 33.9% , 35.8% , 37.5% and 41.7% for the lactating women living in rural areas, with educations at junior high school level and below, with average family incomes under 15 000 yuan per capita in 2012 and who work as household mothers, respectively. These consumption rates for dairy and soybean/nuts were significantly lower than those in women living in cities (48.4%, 55.0%), with an education level of senior high school or above (48.8%, 55.7%), with average family income over 15 000 yuan per capita in 2012 (45.5%, 52.8%) and who work outside the home (43.7%, 49.4%). P values were <0.05 for all comparisons. Conclusion: The daily intake of all foods by lactating women during the first month postpartum was lower than the levels recommended in Chinese Dietary Guideline (2016). The consumption rate of dairy and soybean/nut products during this time period was low, especially for those living in rural areas, with education levels of junior high school and below, with average family incomes less than 15 000 yuan per capita in 2012 and who are housemothers.

Abstract
Insulin resistance and β-cell function are different between the young and elderly diabetes individuals, which are not well elaborated in the nondiabetic persons. The aims of this study were to compare insulin resistance and β-cell function between young and old adults from normal glucose tolerance (NGT) to prediabetes [which was subdivided into isolated impaired fasting glucose (i-IFG), isolated impaired glucose tolerance (i-IGT), and a combination of both (IFG/IGT)], and compare the prevalence of diabetes mellitus (DM) in the above prediabetes subgroups between different age groups after 3 years. A total of 1 374 subjects aged below 40 or above 60 years old with NGT or prediabetes were finally included in this study. Insulin resistance and β-cell function from homeostasis model assessment (HOMA) and interactive, 24-variable homeostatic model of assessment (iHOMA2) were compared between different age groups. The rate of transition to diabetes between different age groups in all pre-diabetes subgroups was also compared. Compared with the old groups, young i-IFG and IFG/IGT groups exhibit higher log HOMA-IR and log HOMA2-S, whereas the young i-IGT groups experienced comparable log HOMA-IR and log HOMA2-S when compared with old i-IFG and IFG/IGT groups. Three prediabetes subgroups all had similar log HOMA-B and log HOMA2-B between different age groups. In addition, the prevalence of diabetes in young i-IFG was statistically higher than that in old i-IFG after 3 years. Age is negatively related to log HOMA2-B in both age groups. Considering an age-related deterioration of β-cell function, young i-IFG, young i-IGT, and young IFG/IGT all suffered a greater impairment in insulin secretion than the old groups. Young i-IFG and IFG/IGT have more severe insulin resistance than the old groups. In addition, young i-IFG characterized with a higher incidence of DM than the old i-IFG. These disparities highlight that the prevention to slow progression from prediabetes to type 2 diabetes should be additionally focused in young prediabetes individuals, especially young i-IFG.

Abstract
BACKGROUND Pancreatic cystic neoplasms (PCN) frequently undergo surgery, given malignant potential. Pancreatic cyst surgery is associated with significant rates of morbidity and mortality. It is crucial to accurately characterize these lesions pre-operatively to avoid unnecessary surgery in patients with benign pancreatic cysts. AIM We aimed to assess the correlation between pre-operative (pre-op) diagnosis based on imaging and clinical presentation, and post-operative (post-op) diagnosis based on histopathology in patients undergone pancreatic cyst surgery. METHODS From January 2000 to January 2012, we randomly selected 2000 patients with ICD-9 code 211.6 and 577.2. Amongst these we identified 281 patients undergone pancreas surgery. Patients with no pre-op imaging or non-cyst indication for surgery were excluded (n = 107). Imaging details, demographics, pre-operative physician diagnosis and histopathologic details of pancreatic cysts were recorded in 174 patients. RESULTS There was a discrepancy between the pre- and post-operative pancreatic cyst diagnosis in 54 (31%) patients. There was no difference in the proportion of various imaging studies (CT, EUS or MRI) between patients with a correct and patients with an incorrect pre-op diagnosis. The pre-op diagnosis was confirmed at pathology in 87.5% of the presumed SCNs, in 80% of the presumed pseudocysts, in 73.3% of the presumed BD-IPMNs, in 66.7% of the presumed MD/mixed-IPMNs and in 53.6% of the presumed MCNs. The accuracy of the pre-operative diagnosis of presumed MCN was significantly lower compared to the non-MCN cysts (53.6% vs. 75%; p = 0.037). Fourteen percent of resections were performed for asymptomatic benign cysts, preoperatively suspected to be potentially pre-malignant cysts. CONCLUSION In nearly 1 out of 3 patients undergone pancreas cyst surgery, there is a discrepancy between pre- and post-op diagnosis. Pre-op diagnosis of presumed MCN is more likely to be incorrect, compared to the other cysts.

Abstract
Objective: To study the prevalence of delayed onset of lactation (later than 3 days) in lactating women in China and to analyze its influencing factors. Methods: Data were extracted from Chinese National Nutrition and Health Surveillance-Mothers, from mothers with children under 2 years of age (in 2013). A total of 11 178 women who were lactating or had lactated were selected from 55 counties of 30 provinces (excluding the Tibet Autonomous Region) in China, using the multi-stage stratified cluster randomization sampling method. Basic information, including onset of lactation, initiation of breastfeeding, breastfeeding difficulties and breastfeeding knowledge were collected using a questionnaire investigation. The prevalence of delayed onset of lactation were analyzed by the weighted processing of complex sampling from the 6th national population census data. A multiple logistic regression was used to analyze the factors associated with delaged onset of lactation. Results: Among 11 178 lactating women, 3 388 had an onset of lactation later than 3 d. The prevalence of delayed onset of lactation was 30.3%. After complex weighting, the prevalence of delayed onset of lactation was 31.2% (95% CI: 25.7%-36.8%) for lactating women in China. Delivery by Caesarean section (OR=1.28, 95%CI: 1.06-1.53) and initiating breastfeeding ≥4 h (OR= 2.34, 95%CI: 1.76-3.11) were the negative factors for delayed onset of lactation. Compared with those living in large cities, lactating women living in medium or small cities (OR=1.39, 95%CI: 1.05-1.84) had a higher risk of delayed onset of lactation. Compared with the lactating women doing housework, the risk of delayed onset of lactation was lower (P<0.05) among those whose occupations were as leaders of Enterprises/Institutions (OR=0.68, 95%CI: 0.47-0.99), in catering and service trades (OR=0.61, 95%CI: 0.43-0.86), in agriculture/forestry/fishery/herdsmen fields (OR=0.65, 95%CI: 0.44-0.96) and who were unemployed (OR= 0.64, 95%CI: 0.46-0.90). Breastfeeding education during pregnancy might lower the risk of delayed onset of lactation (OR=0.78, 95% CI: 0.62-0.98). Conclusion: The prevalence of delayed onset of lactation was relatively high for Chinese lactating mothers. Caesarean section and late initiation of breastfeeding were the primary risk factors. Lactating mothers living in medium or small cities and those doing housework appear to be high-priority groups for intervention. Based on our findings, breastfeeding education during pregnancy is recommended to lower the risk of delayed onset of lactation.

Abstract
Objective: The study aimed to assess the folic acid status of lactating women in China and to analyze factors related to folic acid deficiency in these subjects. Methods: The data on lactating women were extracted from the Chinese National Nutrition and Health Surveillance in 2013. By a multi-stage stratified cluster random sampling method, 10 331 lactating women were selected for the study. The lactating women, 0-24 months postpartum, were from 55 sites in 30 provinces of China, excluding the Tibet Autonomous Region. A standard questionnaire was used to obtain general information and dietary intake during the previous one month period was collected using a food frequency questionnaire. A total of 20% of the total number of lactating women were randomly selected to analyze serum folic acid. Finally, 1 894 lactating women, with questionnaire results and serum folic acid data, were included in the study. Serum folic acid concentrations were analyzed using an electro-chemiluminescence immunoassay method. Folic acid deficiency was defined as a serum folic acid level <2 ng/ml. A multiple logistic regression analysis was used to analyze the factors associated with folic acid deficiency in these women. Results: After excluding abnormal values, 1 894 lactating women were included in the study. Based on our findings, the prevalence of folate deficiency was 3.0% (56/1 894) in lactating women in China. The prevalence of folic acid deficiency was 0.3% (1/388), 1.3% (7/550), 6.0% (38/639) and 3.2% (10/317) in larger, medium or small cities, general rural counties and poor rural counties, respectively. The prevalence of folic acid deficiency was 6.3% (17/269) and 2.4% (39/1 623) for minority and Han ethnic groups, respectively, and was 6.3% (52/823) and 0.4% (4/1 071) for subjects in northern and southern areas of China, respectively. Binary unconditionally logistic regression was used to analyze the factors associated with folic acid deficiency in the lactating women. The results showed that, compared with those living in the south and those in the Han ethnic group, those living in the north and belonging to the minority ethnic group had a greater risk of folic acid deficiency, with (OR=3.63, 95% CI: 1.64-8.05) and (OR=5.42, 95% CI: 1.75-16.74), respectively. With each month of age during childhood, the prevalence of folic acid deficiency decreased by 10% (OR=0.90, 95%CI: 0.85-0.96). Compared with low income subjects, those with middle incomes had OR (95%CI) of 0.25 (0.10-0.60) for folic acid deficiency. A lesser intake of cereal was associated with a greater risk of folic acid deficiency in lactating women (OR=3.04, 95%CI: 1.18-7.79). A lesser intake of tubers was a protective factor for folic acid deficiency in lactating women (OR=0.29, 95% CI:0.12-0.70). Conclusion: The folic acid status of Chinese lactating women has, in general, recently improved. However, living in northern areas, during early lactating periods, belonging to an ethnic minority, living in rural areas, having a low income, lower intake of cereal and excessive intake of tubers were risk factors for folic acid deficiency in lactating women. In these women, folic acid intervention should be considered a priority.

Abstract
Montelukast, a leukotriene receptor antagonist commonly prescribed for treatment of asthma, is primarily metabolized by cytochrome P450 (CYP)2C8, and has been suggested as a probe substrate for investigating CYP2C8 activity in vivo. We evaluated the quantitative role of hepatic uptake transport in its pharmacokinetics and drug-drug interactions (DDIs). Montelukast was characterized with significant active uptake in human hepatocytes, and showed affinity towards organic anion transporting polypeptides (OATPs) in transfected cell systems. Single-dose rifampicin, an OATP inhibitor, decreased montelukast clearance in rats and monkeys. Clinical DDIs of montelukast were evaluated using physiologically based pharmacokinetic modeling; and simulation of the interactions with gemfibrozil-CYP2C8 and OATP1B1/1B3 inhibitor, clarithromycin-CYP3A and OATP1B1/1B3 inhibitor, and itraconazole-CYP3A inhibitor, implicated OATPs-CYP2C8-CYP2C8 interplay as the primary determinant of montelukast pharmacokinetics. In conclusion, hepatic uptake plays a key role in the pharmacokinetics of montelukast, which should be taken into account when interpreting clinical interactions.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) was associated with higher risk of cardiovascular disease (CVD). Low-grade albuminuria was recognized as an early indicator of CVD. Epidemiological studies investigating the association between NAFLD and low-grade albuminuria were limited. AIM To determine whether NAFLD is independently associated with the presence of low-grade albuminuria in Chinese adults. DESIGN A cross-sectional community-based population study was performed in 8270 Chinese adults aged 40 years or older. METHODS A first-voided early morning spot urine sample was obtained for urinary albumin and creatinine measurements. The highest quartile of urinary albumin-to-creatinine ratio was defined as low-grade albuminuria, after excluding the participants with micro- or macroalbuminuria. NAFLD was diagnosed by using ultrasonography findings after the exclusion of alcohol abuse and other liver diseases. RESULTS The prevalence of low-grade albuminuria was significantly higher in participants with NAFLD than in those without NAFLD (33.6% vs. 21.3% in men and 30.4% vs. 22.8% in women, respectively). Multivariate-adjusted logistic regression analysis revealed that NAFLD was significantly associated with increased odds ratio of low-grade albuminuria in men (odds ratio, 1.47; 95% CI, 1.16-1.87) after adjusting for multiple confounders. The significant association was not detected in women. CONCLUSIONS NAFLD was significantly associated with an increased risk of present low-grade albuminuria in middle-aged and elderly Chinese men.

Abstract
Neuroplasticity - the capacity of the brain to change as a response to internal and external pressures - has been studied from a number of different perspectives. Perhaps one of the most powerful models is the study of populations that have been congenitally deprived of a sense. It has been shown that the right Auditory Cortex (AC) of congenitally deaf humans is neuroplastically modified in order to represent visual properties of a stimulus. One unresolved question is how this visual information is routed to the AC of congenitally deaf individuals. Here, we performed volumetric analysis of subcortical auditory and visual brains regions - namely the thalamus (along with three thalamic nuclei: the pulvinar, the lateral geniculate nucleus and the medial geniculate nucleus), and the inferior and superior colliculi - in deaf and hearing participants in order to identify which structures may be responsible for relaying visual information toward the altered AC. Because there is a hemispheric asymmetry in the neuroplastic changes observed in the AC of the congenitally deaf, we reasoned that subcortical structures that also showed a similar asymmetry in their total volume could have been enlisted in the effort of relaying visual information to the neuroplastically altered right AC. We show that for deaf, but not for hearing individuals, the right thalamus, right lateral geniculate nucleus and right inferior colliculus are larger than their left counterparts. These results suggest that these subcortical structures may be responsible for rerouting visual information to the AC in congenital deafness.

Abstract
Acute promyelocytic leukemia (APL) cells exhibit disrupted regulation of cell death and differentiation, and therefore the fate of these leukemic cells is unclear. Here, we provide the first evidence that a small percentage of APL cells undergo a novel cell death pathway by releasing extracellular DNA traps (ETs) in untreated patients. Both APL and NB4 cells stimulated with APL serum had nuclear budding of vesicles filled with chromatin that leaked to the extracellular space when nuclear and cell membranes ruptured. Using immunofluorescence, we found that NB4 cells undergoing ETosis extruded lattice-like structures with a DNA-histone backbone. During all-trans retinoic acid (ATRA)-induced cell differentiation, a subset of NB4 cells underwent ETosis at days 1 and 3 of treatment. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were significantly elevated at 3 days, and combined treatment with TNF-α and IL-6 stimulated NB4 cells to release ETs. Furthermore, inhibition of autophagy by pharmacological inhibitors or by small interfering RNA against Atg7 attenuated LC3 autophagy formation and significantly decreased ET generation. Our results identify a previously unrecognized mechanism for death in promyelocytes and suggest that ATRA may accelerate ET release through increased cytokines and autophagosome formation. Targeting this cellular death pathway in addition to conventional chemotherapy may provide new therapeutic modalities for APL.

Abstract
Diabetic nephropathy (DN) is one of the most frequent complications in diabetes mellitus. This study aimed to explore whether Danshen injection is protective to renal tissue in diabetes. Intraperitoneal injection of streptozotocin (STZ) (60mg/kg) was used to induce diabetes in rats. Some STZ-induced diabetic rats were also intraperitoneally injected with Danshen solution at two different dosages (0.5 or 1ml/kg/day) for 6weeks. Our results showed that serum creatinine (sCr) and blood urea nitrogen were significantly increased in STZ-induced diabetic rats, which was alleviated upon Danshen injection. Danshen injection was also found to ameliorate hypertrophy and dilatation of renal tubule and glomeruli possibly by decreasing the expression of collagen and fibronectin in association with suppression of TGF-β1/Smad pathway. Further investigation revealed that Danshen injection could increase the activity of superoxide dismutase (SOD), and reduce reactive oxygen species (ROS) and malondialdehyde (MDA) levels in STZ-induced diabetic rats, indicating suppression of oxidative stress. In addition, we also found that Danshen injection could suppress IκB/NF-κB signaling pathway and reduce the level of a number of pro-inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in the diabetic renal tissue, indicating suppression of inflammation. In conclusion, our results demonstrated that Danshen injection may rescue STZ-induced diabetic nephropathy, possibly via suppressing the oxidative stress, inflammatory responses and fibrosis progression.

Abstract
Duck Tembusu virus (DTMUV) is an infectious pathogen that can cause epidemics in egg-laying ducks. Here, we isolated and characterized a DTMUV, designated GDLH01, thought to be responsible for the noticeable egg drop in Muscovy duck flocks in South China since 2011. The genome sequence of GDLH01 shared 97-99% homology with other avian-origin Tembusu viruses, and 99.5% homology with the mosquito-borne strain SDMS recently reported in China. Phylogenetic analysis based on the nucleotide sequence of the entire open reading frame confirmed that the isolate was of avian origin and closely related to a mosquito-borne strain. Our findings characterize a novel Tembusu virus circulating in Muscovy ducks in South China and emphasize the importance of reinforcing biosecurity measures and developing vaccines to prevent the spread of this viral pathogen.

Abstract
OBJECTIVE Injection of lipopolysaccharide (LPS) has both promotion and inhibition effects on the autoimmune disease. Given the variable roles of LPS in autoimmune diseases, the role of LPS played in collagen-induced arthritis (CIA, autoimmune disease) model remains to be further determined. MATERIALS AND METHODS CIA was induced by intradermal injection of collagen type II (CII) in DBA/1 mice (day 0) followed by a booster injection on day 21. Mice of CIA with LPS injection group (CIA+ LPS group) were intraperitoneally injected with 50 µg LPS on day 42. Tissues such as carpal joints and fingers were stained with hematoxylin and eosin (H&E) for histopathology analysis. Inflammation, pannus formation and bone resorption were monitored by a macroscopic scoring system. Serum level of IgG2a antibody was determined by enzyme-linked immunosorbent assay (ELISA). RESULTS The incidence of arthritis in CIA group was much higher than that in CIA+ LPS group (100%: 46.5%, p < 0.05), as same as the arthritis score (5.38:1.37, p = 8.16 × 10-6). Besides, the histopathologic score was also higher in CIA group than that in CIA+ LPS group (15.0:5.36). Compared with CIA group, mild synovial hyperplasia and no articular cartilage damage were observed in CIA+ LPS group. Besides, mice of CIA group produced a significantly higher level of IgG2a than CIA+ LPS group (3922 ng/ml: 2084 ng/ml, p = 0.0333) when arthritis developed. CONCLUSIONS Our findings showed that LPS might suppress CIA progression under special conditions, opening up a new understanding of the roles of LPS in arthritis and new possibilities for a clinical therapy of CIA.

Abstract
UNLABELLED To develop a practical process for D-valine preparation from DL-valine, L-valine was used as a sole source of carbon and nitrogen in basal minimal medium to isolate L-valine-degrading micro-organisms. A yeast strain DLPU-zpb was obtained, which showed asymmetric degrading activity against DL-valine. Based on the morphology, physiological and biochemical characteristics, and 26S rDNA D1/D2 domain sequence, strain DLPU-zpb was identified as Candida maltosa. The cells of this strain were used as a biocatalyst for eliminating the L-isomer from DL-valine. The L-isomer was completely degraded within 72 h under the conditions of 30°C, pH control at 6·0, 200 rev min(-1) and 50 g l(-1) DL-valine. The strain DLPU-zpb degraded L-valine effectively but not D-valine, and thus D-valine could be easily isolated from the resultant reaction mixture, which provides a new method for D-valine preparation from DL-valine. SIGNIFICANCE AND IMPACT OF THE STUDY D-valine is an important raw material for medicines and its demand is increasing year by year. Several approaches for D-valine preparation have been reported, but none of them are likely to provide product at low cost. A newly isolated L-valine-degrading yeast strain Candida maltosa DLPU-zpb was described, which showed asymmetric degrading activity against DL-valine. Thus, a new and practical process for D-valine preparation from DL-valine could be developed. This is the first report of the asymmetric degrading ability of C. maltosa against DL-valine and D-valine preparation from DL-valine.

Abstract
AIMS Few studies have analysed the effect of sleep duration and snoring on hypertension and glycaemic control in patients with diabetes. This study aims to investigate the relationship of sleep duration and snoring on prevalent hypertension and glycaemic control in people with diabetes. METHODS In the baseline survey of the REACTION study, 56 032 patients with diabetes were categorized into four groups according to self-reported sleep duration: < 6, 6-7.9, 8-8.9 and ≥ 9 h. Snoring frequency was evaluated as 'usually', 'occasionally' or 'never'. Hypertension was assessed by systolic blood pressure, diastolic blood pressure, self-reported previous diagnosis and antihypertensive medications. 'Good' glycaemic control was defined as HbA1c < 53 mmol/mol (7.0%) and 'poor' glycaemic control as HbA1c ≥ 53 mmol/mol (7.0%). RESULTS Controlling for potential confounders and intermediates, sleep ≥ 9 h relative to intermediate sleep (6-7.9 h) was significantly associated with prevalent hypertension (OR: 1.25, 95% CI: 1.18-1.32) and poor glycaemic control (OR: 1.11, 95% CI: 1.05-1.18), and a U-shaped association was found between sleep duration and prevalent hypertension (P for quadratic trend = 0.019). Usually snoring was positively associated with prevalent hypertension (OR: 1.30, 95% CI: 1.23-1.37), whereas the association between snoring and poor glycaemic control was only on the borderline of statistical significance. CONCLUSIONS Compared with a sleep duration of 6-7.9 h, longer sleep duration was associated with a higher prevalence of hypertension and poor glycaemic control in people with diabetes. Moreover, the relationship between sleep duration and prevalent hypertension was U-shaped. These findings may propose important public health implications for diabetes management.

Abstract
BACKGROUND Autonomic dysfunction (AD) accompanying with chronic liver disorders led to an increased risk of mortality. However, researches that investigated the association between non-alcoholic fatty liver disease (NAFLD) and AD were insufficient. AIMS To study the association of NAFLD with AD in middle-aged and elderly Chinese adults. DESIGN Four thousand nine hundred seventy-four adults aged 40 years or older were enrolled in this cross-sectional study. NAFLD was diagnosed by hepatic B-mode ultrasonography. Autonomic function was assessed using a simple EZSCAN test by measuring sudomotor function, with an AD index > 50% defined as a manifestation of AD. METHODS Pearson correlation, multiple stepwise linear regression, univariate and multivariate logistic regression was employed to examine the relationship between NAFLD and AD, controlling for potential confounders. RESULTS The prevalence of AD was significantly higher in participants with NAFLD than those without (40.75 vs. 26.86%, P < 0.0001). Age, body mass index, status of diabetes, sex, diastolic blood pressure and prevalent NAFLD, were positively correlated with AD index in multiple stepwise linear regression analysis (all P < 0.05), whereas total cholesterol was negatively related to it (P = 0.0043). Compared with the participants without NAFLD, those with NAFLD had an increased odds of the prevalent AD (odds ratio 1.38; 95% confidence interval 1.15-1.64; P = 0.0004) after controlling for multiple confounders. CONCLUSIONS The presence of NAFLD was significantly associated with AD, as indicated by abnormal sudomotor function. The association was independent from various conventional risk factors.

Abstract
OBJECTIVE Progressive β-cell dysfunction hinders the maintenance of glycaemic control in type 2 diabetes, but comparative data on β-cell-protective therapies are lacking in the early stage of type 2 diabetes. Here we evaluated the comparative glycaemic efficacy and impact on β-cell function of three antihyperglycaemic agents that have a β-cell-protective effect, exenatide, insulin and pioglitazone, in newly diagnosed patients with type 2 diabetes. DESIGN AND METHODS In this 48-week, multicentre, parallel-group study, 416 patients newly diagnosed with type 2 diabetes were randomly assigned 1 : 1 : 1 to receive exenatide, insulin or pioglitazone. The primary end-point was the change in glycosylated haemoglobin (HbA1c) from baseline. Secondary end-points included effects on weight, blood pressure, lipid profiles and β-cell function assessed by homeostasis model assessment, fasting proinsulin:insulin (PI/I), disposition index (DI) and acute insulin response (AIR). RESULTS At week 48, mean [95% confidence interval (CI)] HbA1c changes from baseline were -1.8% (-1.55% to -2.05%) with exenatide, -1.7% (-1.52% to -1.96%) with insulin and -1.5% (-1.23% to -1.71%) with pioglitazone. Treatment differences were -0.20% (95% CI -0.46% to 0.06%) for exenatide versus insulin (P = 0.185), and -0.37% (95% CI -0.63% to -0.12%) for exenatide versus pioglitazone (P = 0.002). Significant improvements from baseline in AIR, PI/I and DI were observed with all treatments, with the greatest improvements in DI, as well as weight, blood pressure and lipid profile, observed with exenatide. CONCLUSIONS All three agents showed efficacy regarding glycaemic control and metabolic benefits; however, exenatide showed the greatest efficacy. β-cell function improved in all treatment groups; hence, early initiation of β-cell-protective therapy may halt the decline in β-cell function in type 2 diabetes.

Abstract
AIM Studies with metformin suggest a favourable change in β-cell function over sulphonylureas in the early course of obese type 2 diabetes mellitus (T2DM), but it remains unclear whether a similar effect is observed in non-obese individuals. Here we investigated the effects of metformin or glipizide gastrointestinal therapeutics system extended-release formulation (GITS) on β-cell function in non-obese patients with newly diagnosed T2DM. METHODS A total of 160 newly diagnosed patients with fasting glucose 7.0-13.0 mmol/L and body mass index <30 kg/m(2) from five centres in China were randomized to metformin or glipizide GITS for 24 weeks. Early insulin secretion [the ratio of area under the curve (AUC) of insulin to glucose during 0-30 min (InsAUC30 /GluAUC30 )] and insulin sensitivity [Matsuda index (ISIM )] were assessed during the standard meal tolerance test before and after therapy. Plasma glucagon-like peptide-1(GLP-1) and glucagon levels were also measured. RESULTS Metformin improved InsAUC30 /GluAUC30 significantly (from 8.1 ± 0.6 pmol/mmol to 10.7 ± 0.7 pmol/mmol, p < 0.05), comparable to results with glipizide GITS. In the metformin-treated lean (body mass index < 25 kg/m(2) ) subgroup, the increase in ISIM was not significant, but the improvement in InsAUC30 /GluAUC30 was of great magnitude. Increased GLP-1 responses during meal tolerance test and decreased fasting glucagon level were observed after metformin treatment. Correlation analysis showed that the improvement of InsAUC30 /GluAUC30 was associated with the changes in HbA1c (r = -0.374, p = 0.000), ISIM (r = 0.356, p = 0.001), and ΔGLP-10-30 (r = 0.225, p = 0.02). CONCLUSIONS Metformin improved β-cell function in non-obese subjects with newly diagnosed T2DM, which was partly independent of the change in insulin sensitivity in these subjects. This study provides evidence-based data to support metformin use in non-obese patients with T2DM as the first-line agent, which can improve both insulin sensitivity and β-cell function.

Abstract
PURPOSE To evaluate the efficacy of two-step retrograde closed stenting for treating canalicular laceration. methods: Forty-eight consecutive canalicular laceration cases (48 eyes) were randomised and divided into two groups: a one-step group and a two-step group. In the two-step group (23 cases), the first step was performed in the outpatient department and included identifying the medial cut end of the canaliculus and probing under a slit-lamp microscope, followed by a retrograde canalicular stenting assisted by a memory titanium stylet. The second step was canalicular anastomosis, which was performed in the operating room. In the one-step group (25 cases), all of the surgical procedures were performed when preoperative preparations were simultaneously available. RESULTS The time elapsed from the doctor visit to the treatment was 4.3 ± 2.4 h in the two-step group and 18.8 ± 6.3 h in the one-step group (P<0.01). The canalicular medial cut ends were found in all cases, but 8.6 ± 3.5 min was needed in the two-step group, and 51.4 ± 24.2 min was needed in the one-step group (P<0.01). The numerical rating scale for pain during surgery was 1.8 ± 1.2 in the two-step group and 5.4 ± 2.2 in the one-step group (P<0.01). One case (2.63%) in the two-step group and nine cases (36%) in the one-step group required other assisted methods to locate the medial cut end (P=0.007). Twenty-one cases (91.3%) in the two-step group and 20 cases (80%) in the one-step group achieved patent lacrimal drainage systems during a 12-month follow-up (P=0.528). CONCLUSIONS The two-step canalicular anastomosis method allows an early search for the medial cut end of the canaliculus and improves the chances of finding it; it is also a quicker, less invasive method for treating canalicular lacerations.

Abstract
Hepatic progenitor cells (HPCs) are a potential cell source for liver cell
transplantation but do not function like mature liver cells. We sought an
effective and reliable method to induce HPC maturation. An immortalized HP14.5
albumin promoter-driven Gaussian luciferase (ALB-GLuc) cell line was established
from HPCs isolated from fetal mouse liver of post coitus day 14.5 mice to
investigate the effect of induction factors on ALB promoter. HP14.5 parental
cells were cultured in DMEM with different combinations of 2% horse serum (HS),
0.1 µM dexamethasone (DEX), 10 ng/mL hepatic growth factor (HGF), and/or 20
ng/mL fibroblast growth factor 4 (FGF4). Trypan blue and crystal violet staining
were used to assess cell proliferation with different induction conditions.
Expression of hepatic markers was measured by semi-quantitative RT-PCR, Western
blot, and immunofluorescence. Glycogen storage and metabolism were detected by
periodic acid-Schiff and indocyanine green (ICG) staining. GLuc activity
indicated ALB expression. The combination of 2% HS+0.1 µM Dex+10 ng/mL HGF+20
ng/mL FGF4 induced the highest ALB-GLuc activity. Cell proliferation decreased
in 2% HS but increased by adding FGF4. Upon induction, and consistent with
hepatocyte development, DLK, AFP, and CK19 expression decreased, while ALB,
CK18, and UGT1A expression increased. The maturity markers tyrosine
aminotransferase and apolipoprotein B were detected at days 3 and 6
post-induction, respectively. ICG uptake and glycogen synthesis were detectable
at day 6 and increased over time. Therefore, we demonstrated that HPCs were
induced to differentiate into functional mature hepatocytes in
vitro, suggesting that factor-treated HPCs may be further explored
as a means of liver cell transplantation.

Abstract
Adipogenesis, the development from preadipocytes or mesenchymal stem cells (MSCs) to mature adipocytes, is regulated by a network of signaling pathways and transcription factors. The involvement of Notch signaling and its effector HES1 in adipogenesis has been investigated in several studies with conflicting results. The underlying mechanisms remain unclear because of the lack of information about HES1 target genes during adipocyte differentiation. As a novel gene transiently up-regulated in early adipogenesis, FAD24 functions as a positive regulator of adipocyte differentiation in both preadipocytes and MSCs. In the present study, we report that the expression level of FAD24 is inversely associated with that of HES1 in porcine MSCs after adipogenic induction. Enforced overexpression of HES1 in MSCs during the early stage of adipogenesis significantly repressed the transcription of FAD24 (P < 0.01) and the other pro-adipogenic genes (P < 0.05), resulting in reduced intracellular lipid accumulation. Sequence analysis showed that porcine FAD24 harbors an evolutionarily conserved HES1 binding site in its proximal promoter region. Functional HES1, but not its dominant-negative mutant, markedly reduced the promoter activity of FAD24 (P < 0.01). Site-directed mutation and chromatin immunoprecipitation further confirmed that HES1 inhibits FAD24 transcription by direct binding to the promoter. Taken together, we identified FAD24 as a novel downstream target of HES1 during adipogenesis. Our data suggest that HES1-mediated repression of FAD24 transcription at the early stage of adipocyte differentiation may contribute to the impaired adipogenesis induced by the Notch-HES1 signaling pathway.

Abstract
Yersinia pestis, the causative agent of plague, is proved to be a recently emerged clone from Y. pseudotuberculosis. However, the diseases they cause and their patterns of transmission are very different. People always focus on the genetic changes between Y. pestis and Y. pseudotuberculosis to reveal their pathogenic differences, and little is known about host defence differences to these two Yersinia. In this study, the effects of Y. pestis and Y. pseudotuberculosis on macrophages were analysed. Cell apoptosis showed significant difference after the macrophages were infected by these two strains, and caspase-3 activity also demonstrated a similar tendency. Further, macrophage function activities were evaluated. We found during the early infection of Y. pestis, several basic functions of macrophages, including phagocytosis, secretion of cytokine tumour necrosis factor-α and nitric oxide, macrophage polarity and antigen presenting, were significantly interrupted. In comparison, Y. pseudotuberculosis infection showed lower inhibition on macrophages. Especially, Y. pestis infection might cause macrophage to polarize to M2 macrophages in the early phase, compared with Y. pseudotuberculosis infection, which was different from the common acute infection. These results clearly indicated even in the early stage of infection, different host macrophage defence patterns could help us to understand the obvious virulence differences between Y. pestis and Y. pseudotuberculosis.

Abstract
Adipokines omentin-1 and adiponectin have been reported to improve insulin resistance. It is known that insulin sensitizers exenatide, avandamet, or diet change from high-fat to normal chow ameliorate metabolic disorders. However, whether these treatments increase omentin-1 levels in high fat-diet animals and the relationship between omentin- 1 and adiponectin remain largely unknown. We investigated the effect of insulin sensitizers exenatide and avandamet, and of dietary change on these adipokine levels, body weight, and insulin sensitivity in diet-induced obese rats. Obesity was induced in rats by high-fat diet feeding for 8 weeks, and then the rats were given exenatide, avandamet and diet change to normal chow, respectively, for additional 8 weeks. Compared to the high-fat control group, exenatide and avandamet treatment significantly induced adipose gene expression and elevated the circulation levels of omentin-1 and adiponectin, whereas they decreased the leptin gene expression and circulation level, which is associated with improvement of systemic insulin sensitivity and the glucose and lipid profile. Notably, there was a significant positive correlation between omentin-1 and adiponectin in the above regimens, suggesting that omentin-1 and adiponectin may contribute to the insulin-sensitizing effect of exenatide and avandamet.

Abstract
OBJECTIVES To modify the method for creating an abdominal aortic aneurysm in rabbits, and to study its performance. MATERIALS AND METHODS A total of 24 New Zealand white rabbits were induced topically with 10 μl of porcine elastase (0, 0.1, 5 and 10 units μl(-1)) to define the optimal concentration (groups A-D). Twelve aneurysms were induced with 10 units μl(-1) of 10 μl elastase to serve as a follow-up group (group E) to serve as a follow-up. A 1.5-cm aortic segment was isolated and induced with elastase solution for 30 min. RESULTS All animals in groups D and E developed AAA by day 5. Aneurysms in Group E were stable over 100 days. Partial destruction to disappearance of elastic lamellae and smooth muscle cells (SMCs) was seen in elastase-treated animals by day 5. Regenerated elastin and proliferated SMCs were present in group E. Matrix metalloproteinases 2 and 9 and RAM11 showed strong expression in group D, but expression decreased in group E after day 15. CONCLUSIONS The rabbit AAA model induced via topical application of porcine elastase at 10 units μl(-1) for 30 min appears easy and simple, with shorter induction and more rapid aortic dilation. The model is stable over 100 days and is useful to study the formation and progress of AAAs.

Abstract
Raspberry (Rubus idaeus L.) is a valuable and widely grown softfruit that is a host for 40 viruses and virus-like agents, of which many are not characterized at the molecular level. Recently, Raspberry leaf blotch virus (RLBV, putative emaravirus species) was described from raspberries (cv. Glen Ample) in the United Kingdom and Serbia. Plants displayed conspicuous yellow blotches on leaves and abnormal development of leaf hairs in the corresponding areas of the abaxial side (3). Similar symptoms were observed in 'Glen Ample' grown in protective plastic tunnels and open fields in the main berry growing area in eastern Finland in June 2011. In three farms, leaves were sampled from symptomatic and symptomless plants of 'Glen Ample' and also cv. Polka displaying no symptoms. Total RNA was extracted using CTAB reagent. Equal amounts of RNA were pooled from 13 samples and subjected to small-RNA (sRNA) deep sequencing (Fasteris SA, Plan-les-Ouates, Switzerland) to detect viruses without advance information (2). Contigs were built on 21- to 24-nt sRNA reads using Velvet. Contigs larger than 50 nt were used to search homologous sequences in GenBank by BLAST and significant similarity (up to 99%) was observed with RLBV RNA3 and RNA4. Mapping sRNA reads to the genome of RLBV (1) by MAQ resulted in significant coverage of RNA1 (16%), RNA2 (37%), RNA3 (46%), RNA4 (65%), and RNA5 (27%). cDNA was synthesized on RNA of one symptom-expressing plant using random hexamer primers and the cDNA tested by PCR with a forward primer (RLBV-F 5'-TCAAATCCACTTGCATAGAACC-3', nt 723 to 744) and reverse primer (RLBV-R1 5'-CCTCAAACCTTGCAAACACA-3', nt 1,318 to 1,337) designed according to the nucleocapsid (NP) gene of the Scottish RLBV isolate (3). The sequence of the amplified partial NP gene (576 nt; GenBank Accession No. JQ684678) was 92.8% and 94.8% identical to the Scottish isolate at nt and amino acid levels, respectively. The forward primer RLBV-F and a new reverse primer (RLBV-R2 5'-GCCGAAAGTCAAACCTGGTG-3', nt 943 to 962) were used to test additional plants for RBLV and to make a probe (198 nt) to detect RLBV using digoxigen-labeled sense and antisense RNA probes, as described for European mountain ash ringspot associated virus (1). RLBV was detected in all tested plants of 'Glen Ample' with yellow leaf blotch symptoms in the three farms, but not in any symptomless plants of 'Glen Ample' and 'Polka.' The sense probes gave strong signals, in contrast to the antisense probes, which gave only weak or no detectable signals in the virus-positive plants, consistent with the negative RNA strand of RLBV being encapsidated in virus particles. The results show RLBV is associated with severe, distinct, and characteristic symptoms in raspberries of cv. Glen Ample grown in plastic tunnels and open fields in Finland and has an apparent negative impact on plant growth and yield. Our observations in 2011 also suggest that the incidence of diseased plants is much higher in plastic tunnels than in open fields, perhaps because the conditions for the vector of RLBV (raspberry leaf and bud mite, Phyllocoptes gracilis Nalepa) (1) are more favorable in plastic tunnels. These results clarify the etiology of raspberry leaf blotch disease in Finland and emphasize the need to inspect raspberry planting materials for RLBV for better control of the disease.

Abstract
T helper 17 (TH17) cells have well-described roles in autoimmune diseases. The immune modulations of development and function of TH17 have become a key issue. In this review, we summarize the recent findings regarding the direct and indirect signalling regulatory mechanisms of TH17 cells in the general mouse model of autoimmune diseases and other human diseases.
