Abstract
Before the Song Dynasty, the main processing method of Pinelliae Rhizoma was soup washing. The "new method" in Taiping Huimin Heji JuFang is a processing method that concocted with Ginger,white alum and starter-making.The "Fa Banxia" in the Yuan Dynasty's Yuyuan Yaofang comes from the Taiping Huimin Heji JuFang, and the Fa Wen Banxia, Fa Bai Banxia, and Fa Hong Banxia are the processing methods of patent medicine with a variety of other herbs.Fa Banxia appeared in the Ming Dynasty, and its auxiliary materials were ginger and white alum, and medical formulary began to include formulas containing Fa Banxia. Bencao Gangmu abbreviates the Yuan Dynasty's Fabai Banxia as "Fa Banxia", and is elaborated under the item attached "prescription" item instead of the "treatment". In the literature of Materia Medica, it is recorded that the preparation of auxiliary materials in Fa Banxia increased, including lime, licorice, soap horn, and simple nitro.After Daoguang in the Qing Dynasty, the Fa Banxia in famous medical cases was more used, and at that time, Fa Banxia was Xian Banxia. There are two recipes for Xian Banxia: one is made with seven processes, and the other is soaked in alum licorice water. During the Republican period, Zhang Cigong also pointed out that Fa Banxia was sliced Xian Banxia after rinsing and boiling, while the preparation method of Xian Banxia was Banxia made of ginger and white alum.Ye Juquan pointed out that the so-called "fa" is neither an ancient method nor a new method, questioning the process of repeated immersion in Banxia. After 1949, the questioning of Fa Banxia continued unceasing.Influenced by this, the 1960 edition Beijing Traditional Chinese Medicine Slice Cutting Experience included the method of soaking alum, licorice ,lime water, and was included in the 1963 edition of the Pharmacopoeia of the People's Republic of China.The 1985 version reduced the soaking time and eliminated the soaking process of alum based on the 1963 version, and this method is still used today.

Abstract
Objective: To investigate the efficacy and safety of interventional endobronchial one-way valves (EBV) for the treatment of peripheral bronchopleural fistula (BPF). Methods: A total of 33 patients with peripheral BPF who underwent EBV implantation in Endoscopy Center of Shanghai Pulmonary Hospital from August 2017 to December 2021 were selected as the research objects. All the patients were diagnosed with peripheral BPF before the implantation surgery. The detailed medical records of the patients were collected, and the etiology, lesion location, treatment method and operation process, treatment efficacy and postoperative complications were analyzed to evaluate the efficacy and safety of EBV implantation. Results: Of the 33 patients in our study, 26 were male and 7 were female. The median age was 54.7 (28-86) years. There were 18 cases of BPF after thoracic surgery (54.5%), 6 cases of chronic obstructive pulmonary disease complicated with spontaneous pneumothorax (18.2%), and 12 cases of pulmonary tuberculosis and non-tuberculous mycobacterial infection with spontaneous pneumothorax (36.4%). A total of 63 valves were inserted in the 33 cases, and a maximum of valves and at least one were inserted in a single case. The lesions were located in the right lower lobe in 16 cases (48.5%) and the left upper lobe in 12 cases (36.4%). Of the 33 patients undergoing EBV placement, 22 (66.7%) were successful, with chest drainage tube indwelling duration of (88.5±36.6) days and (29.6±11.4) days, respectively, before and after EBV treatment. The time from EBV placement to successful withdrawal of EBV was (102.2±31.3) days. During a postoperative follow-up of 6 months after EBV treatment, the main complications were 29 cases with attachment of secretions to the EBV (90.6%) and 13 cases (40.6%) with mild granulation proliferation. In addition, there were five patients with moderate to severe granulation proliferation (15.6%), one with valve displacement or shedding (3.1%), and one with bleeding (3.1%). Conclusions: In this study, the success rate of EBV placement and occlusion was 66.7%. Transbronchoscopic EBV placement in the treatment of peripheral BPF is a effective treatment with relatively minor complications.

Abstract
Shen Qu was distiller's yeast in Qi Min Yao Shu, the most completely preserved of the ancient Chinese agricultural texts in the North Dynasty. The making process of Shen Qu (medicated leaven) in this book had far-reaching influence on the processing of Liu Shen Qu. In terms of pharmaceutical composition, Flour-qu in Shen Qu, which developed into Whole-bran-wheat-qu and then Bran-qu, is still used up to this day. The use of polygonum, as a supplementary material from the buckwheat and knotweed family polygonaceae, was gradually narrowed to polygonum hydropiper and polygonum orientale. In terms of production and processing, fresh herbs were developed from boiling or boiling and juicing in parallel. Wheat processing was simplified from the method of raw wheat, steaming and frying together into the method of using raw wheat only. Psychrometrics of Qu-cake "Sou Yu Gang" is still taken as the measurement of production and processing today. The method of shaping Qu-cake evolved to hand kneading and moulding. The covering material of Qu-cake was developed from wheat straw and Artemisia annua to Vitex negundo. The wrapping material of Qu-cake were Ramie leaves, broussonetia papyrifera leaves and paper. Some techniques in the processing, such as Fan-qu, Ju-qu and Wengsheng, were lost in the historical development of the making method of Shen Qu. The drying method was developed from hanging clusters of Qu-cakes to hanging single paper wraped cakes alone. As a mainstream processing method, Yan-qu was then developed into the methods of Fengqu and Zao Jiang Huang. The making method Bao-qu, which outdated Qu was added, and is still the method of Yan-qu. In this sense, current production and processing technology of Yan-qu and Zao Jiang Huang came from Qi Min Yao Shu.The issues for further studies are: the use of Artemisia annua, Polygonum hydropiper and Xanthium sibiricum, Qu-cake moulding, single strain fermentation or dominant population fermentation, the Feng-qu method, the materials for covering and wrapping Qu-cake, and comparison between Flour-qu, Whole bran wheat- qu and Bran-qu.

Abstract
BACKGROUND AND AIM It has been reported that serum quantification of anti-HBc (qAnti-HBc) could predict antiviral response in chronic hepatitis B (CHB) patients, while its role in hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) remains unclear. Its implication in HBV-ACLF was evaluated in this study. METHODS Baseline serum qAnti-HBc levels were retrospectively detected in HBV-ACLF and CHB patients using recently developed double-sandwich immunoassay. The association of qAnti-HBc level with clinical outcomes was evaluated by multiple logistic regression. Nomogram was adopted to formulate an algorithm incorporating qAnti-HBc for the prediction of survival in HBV-ACLF. The post-hospitalization of HBV-ACLF patients were followed-up for 1 year. RESULTS Eighty-eight HBV-ACLF as training set, 80 HBV-ACLF as validation set and 216 CHB cases were included. Serum qAnti-HBc level was significantly higher in HBV-ACLF (4.95 ± 0.54 log10 IU/mL) than CHB patients (4.47 ± 0.84 log10 IU/mL) (P < 0.01). Among HBV-ACLF cases, both in training and validation set, patients with poor outcomes had lower qAnti-HBc level. Area under receiver operating characteristic curve of the novel qAnti-HBc inclusive model was 0.82, superior to 0.73 from model for end-stage liver disease scores (P = 0.018), which was confirmed in validation set. During follow-up, the qAnti-HBc level declined at month 3 and month 6, then plateaued at 3.84 log10 IU/mL. CONCLUSIONS Serum qAnti-HBc level was associated with disease severity and might be served as a novel biomarker in the prediction of HBV-ACLF clinical outcomes. The underlying immunological mechanism warrants further investigation.

Abstract
Qimin Yaoshu(, Essential Techniques for the Welfare of the People), written in the Northern Wei Dynasty, had a specific record of process of boiling down gelatin, it involved 12 steps. Comparing with the methods of later generations, we find that the main differences lie in 6 aspects: shaving hair, adding accessories, duration and degree of heating for gel-forming, preventing gelatin from scorching, drying method, checking water quality. Especially, it is considered that the experience of no hair shaving and excipients adding is of great reference value to the cooking methods of modern donkey-hide gelatin and ox-hide gelatin.

Abstract
AIMS High glucose (HG)-induced pancreatic β-cell apoptosis may be a major contributor to the progression of diabetes mellitus (DM). NADPH oxidase (NOX2) has been considered a crucial regulator in β-cell apoptosis. This study was designed to evaluate the impact of GLP-1 receptor agonist (GLP-1Ra) liraglutide on pancreatic β-cell apoptosis in diabetes and the underlying mechanisms involved. METHODS The diabetic rat models induced by streptozotocin (STZ) and a high fat diet (HFD) received 12 weeks of liraglutide treatment. Hyperglycemic clamp test was carried out to evaluate β-cell function in vivo. Flow cytometry analysis was used to measure apoptosis rates in vitro. DCFH-DA method was used to detected ROS level in vivo and in vitro. RESULTS Liraglutide significantly improved islet function and morphology in diabetic rats and decreased cell apoptosis rates. Thr183/Thr185 p-JNK1/2 and NOX2 levels reduced in diabetic rats and HG-induced INS-1 cell following liraglutide treatment. In addition, liraglutide upregulated the phosphorylation of AMPKα (p-AMPKα), which prevented NOX2 activation and alleviated HG-induced β-cell apoptosis. CONCLUSION The p-AMPKα/NOX2/JNK1/2 pathway is essential for liraglutide to attenuate HG-induced β-cell apoptosis, which further proves that GLP-1Ras may become promising therapeutics for diabetes mellitus.

Abstract
Objective: To investigate the drinking status and associated factors in adults in China. Methods: Based on the 2010-2012 China National Nutrition and Health Survey (CNNHS), a total of 135 824 participants aged ≥18 were included in this cross-sectional analysis. Multivariable logistic regression model was used to investigate the associated factors for drinking status. Results: The overall drinking rate was 30.5% in Chinese adults, 53.8% in men, and 12.2% in women. The excessive drinking rate was 14.0% in men and 1.1% in women. The daily drinking rate was 25.7% in men and 10.9% in women. Men mainly consumed multi-type wines, but women preferred beer. The overall harmful drinking rate was 7.1%. The excessive drinking rate, daily drinking rate, and harmful drinking rate increased first but then declined with age. All the four rates were positively related with physical activity. Conclusions: The drinking rate, excessive drinking rate, daily drinking rate and harmful drinking rate were high in adults in China. Drinking status was associated with age, sex, marital status, education level, smoking status and physical activity.

Abstract
Objective: To analyze the average systolic blood pressure (SBP) and diastolic blood pressure (DBP) among adults aged 18 years old and above in China between 2010 and 2012; and to compare the difference in the results measured by mercury sphygmomanometer and converted electronic sphygmomanometer. Methods: The data was collected from Chinese Nutrition and Health Surveillance in 2010-2012. 120 428 adults aged 18 years old and above were selected from 150 survey counties (districts) of 31 provinces in China Mainland, by multi-stage stratified and probability proportion to size (PPS) cluster randomization sampling method. The average blood pressure value was calculated from three systolic and diastolic blood pressure readings measured by mercury sphygmomanometer. The value of Electronic Sphygmomanometer was converted by regression formula. Age-standardized results were calculated incorporating a complex sample weighting using the population data from the National Bureau of Statistics in 2009. Results: The overall adjusted mean of SBP based on the value of mercury sphygmomanometer among Chinese adults aged 18 years old and above was 122 mmHg (1 mmHg=0.133 kPa), 124 mmHg in men and 120 mmHg in women. The average SBP value was separately 115, 127, and 137 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average SBP was 122 mmHg in urban and 122 mmHg in rural areas. Mean DBP was 78 mmHg, 79 mmHg in men and 76 mmHg in women. The average DBP was separately 75, 81, and 81 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was 78 mmHg in urban and 77 mmHg in rural areas. The overall adjusted mean of SBP based on converted electronic device was 129 mmHg,130 mmHg in men and 127 mmHg in women, respectively. The mean of SBP was separately122, 134, and 143 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. Mean SBP was both 129 mmHg in urban and in rural areas. Mean DBP was 76 mmHg, 78 mmHg in men and 75 mmHg in women, respectively. The average DBP was separately 74, 79, and 79 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was both 76 mmHg in urban and rural areas. Conclusion: The average SBP and DBP was different between the mercury sphygmomanometer and converted electronic device. However, the results from both measures showed that the blood pressure was higher in men than in women, the blood pressure increased with the increase of age, and there was no difference between urban and rural areas.

Objective: To analyze the epidemiological characteristics of waist circumference and abdominal obesity among Chinese children and adolescents aged 6-17 years. Methods: Data was from the samples of aged 6-17 years in the China National Nutrition and Health Surveillance program in 2010-2012. P(90) (the same age, the same sex) was used as the diagnostic value for abdominal obesity. Results: The overall waist circumference of children and adolescents in all the age groups appeared higher in males than that in females (P<0.000 1), higher in cities than that in the rural areas (P<0.05), and higher in children with high family income than those with middle or low family incomes (P=0.000 3). The rate of abdominal obesity in children and adolescents aged 6-17 years appeared as 11.2% on average and 10.7% and 11.8% for boys and girls, respectively but with no significant difference (P>0.05). Rates on abdominal obesity appeared as 13.2% and 8.5% for boys while as 12.3% and 11.2% for girls respectively, in urban or rural areas. As for the levels of family income, the abdominal obesity rates appeared as 15.8%, 11.5% and 8.8% respectively for boys while 13.5%, 11.9% and 11.6% respectively for girls, under high, middle and low levels of family income. Conclusion: The rate of abdominal obesity in boys seemed more responsive to the impact of income in urban or rural areas.

Abstract
Objective: To analyze the relationship between family-related factors and the status of overweight and obesity in children and adolescents aged 6-17 years in China. Methods: Data were collected from the China National Nutrition and Health Surveillance in 2010-2012 program. A sample of 6 343 subjects aged 6-17 years was selected, with matched weight, education levels, household income and other family related factors of their parents. Univariate analysis and multivariate logistic regression were used to explore the relationship between family factors and overweight and obesity in school-aged children and adolescents. Results: After adjusted for age, gender and region, results from the multivariate logistic regression showed that both the overweight and obesity of children and adolescents were associated with maternal BMI (OR=1.83, 95%CI: 1.63-2.05), paternal BMI (OR=1.74, 95%CI: 1.57-1.94), mother's educational level (OR=1.24, 95%CI: 1.12-1.37) and household income (OR=1.30, 95%CI: 1.15-1.46). Conclusion: Factors as overweight or obesity status of the parents, mother's educational level and household income were positively correlated with the prevalence of overweight and obesity in Chinese children and adolescents.

Abstract
Objective: To study the prevalence and characteristics of overweight and obesity among Chinese children aged 0-5 years, in 2010-2013. Methods: Data was from the'China Nutrition and Health Surveillance-0-5-Years-Old Children and Lactating Women'project in 2013. Stratified multistage cluster sampling method was used to select 55 districts/counties from 30 provinces (autonomous regions, municipalities) with the sample size of children as 32 862. Definition of overweight and obesity were according to both the WHO 2006 growth standard in children less than 5-year-old and the WHO 2007 growth reference in children of 5-years-old. Results: were calculated by complex weight based on national census from the National Bureau of Statistics in 2010. Results The overall prevalence of overweight was 8.4% among the 0-5-year-old in 2013, with 9.4% in boys and 7.2% in girls. Both of the rates from urban and rural areas were the same, as 8.4%. The prevalence rates of overweight in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups appeared as 13.0%, 11.1%, 8.3%, 6.0%, 4.8%, 3.9% and 15.9%, respectively. The rates of overweight in low, medium and high income families were 8.0%, 8.8% and 8.9%, respectively. The prevalence of obesity was 3.1% among the 0-5-year-old, with 3.6% in boys and 2.5% in girls. There was no significant difference seen in urban (3.3%) and rural areas (2.9%). The prevalence rates for obesity in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups were 5.8%, 3.8%, 2.5%, 1.6%, 1.2%, 1.3% and 7.8%, respectively. The rates of obesity in low, medium and high income families were 2.8%, 3.3% and 3.5%, respectively. Conclusion: The prevalence rates of both overweight and obesity were increasing among the 0-5-year-olds in China, suggesting that it is necessary to timely conduct the surveillance and intervention programs on overweight and obesity in this target population.

Abstract
Objective: To analyze the prevalence rates of overweight and obesity in Chinese children and adolescents aged 6-17 years, and to provide scientific basis for the development of prevention strategies on obesity. Methods: Data was from children and adolescents aged 6-17 years in the China National Nutrition and Health Surveillance 2010-2012 program. In children aged 6 years, criteria of overweight and obesity were followed the WHO growth reference for school-aged children and adolescents. In children and adolescents aged 7-17 years, overweight and obesity were defined by sex and age specific BMI, recommended by Guidelines for prevention and control of overweight and obesity among school-age children and adolescents according to the Chinese guidelines. Results: The overall rates on overweight and obesity were 9.6% and 6.4% among the Chinese children and adolescents aged 6-17 years, with 11.0% (12.8% for boys and 9.0% for girls) in urban and 7.7% (boys 9.7%, girls 5.5%) in rural areas. The rates of overweight and obesity among children and adolescents were 8.4% (boys 9.3%, girls 7.4%) and 5.2% (boys 6.2%, girls 4.1%) in the rural areas. According to the levels of household income, the overweight rates of children in high, middle and low incomes were 12.3%, 10.7% and 8.2%, with obesity as 8.6%, 7.2% and 5.7% respectively. Conclusions: In 2012, the prevalence rates of overweight and obese were 9.6% and 6.4% among children and adolescents aged 6-17 years, respectively, higher in urban than in rural areas and higher boys than in girls. The prevalence rates of overweight and obesity seemed to be related to the levels of household income.

Abstract
Background Protective effects of reduced beta 2 glycoprotein I (Rβ2GPI) against vascular injury of diabetes mellitus have been extensively investigated. However, the effects of Rβ2GPI on liver injury in diabetic animals have not been reported. Material/Methods A diabetic rat model of was produced by systemic injection of streptozotocin (STZ). Rats were divided into a normal control group, a model group, and an Rβ2GPI treatment group (N=6 in each group). After treatments, blood serum and liver tissue were collected to test the protection of Rβ2GPI. AMP-activated protein kinase (AMPK) was detected by immunohistochemistry and Western blotting. Results Our results revealed that Rβ2GPI reduced blood glucose, serum creatinine, and urea nitrogen levels, as well as serum inflammation cytokines, including interleukin (IL)-6, tumor necrosis factor (TNF)-a and C-reactive protein in the diabetic rats. Importantly, Rβ2GPI prevented liver injury in the diabetic rats as confirmed by hematoxylin-eosin (H&E) staining, alanine transaminase, aspartate transaminase, and gamma-glutamyl transferase. Reactive oxygen species (ROS) were promoted by diabetic modeling and were attenuated by Rβ2GPI administration. Moreover, Rβ2GPI significantly reduced liver catalase, malondialdehyde, and superoxide dismutase levels in the diabetic rats. Rβ2GPI reduced liver glycolipid storage in STZ diabetic rats. Both immunohistochemistry and Western blotting demonstrated that Rβ2GPI promoted AMPK phosphorylation in the diabetic rats. Conclusions Our data proved that Rβ2GPI prevented liver injury in diabetic rats, likely through activating the AMPK signaling pathway.

Abstract
BACKGROUND Adipocyte fatty acid-binding protein (A-FABP) has been recognized as an important player in macrophage cholesterol trafficking and inflammation, and may promote the development of atherosclerosis. To further elucidate the role of A-FABP in atherosclerosis in diabetes, we investigated the relationship between serum A-FABP concentrations and peripheral arterial disease (PAD) in patients with type 2 diabetes mellitus (T2DM). METHODS In all, 488 inpatients with T2DM were enrolled in the study (254 men, 234 women; mean (±SD) age 57.3 ± 13.0 years). The severity of peripheral arterial stenosis was assessed by ultrasound examination. Serum A-FABP concentrations were determined by ELISA. RESULTS Serum A-FABP concentrations were significantly higher in patients with than without PAD (8.0 ± 3.3 vs 6.2 ± 1.6 ng/mL, respectively; P < 0.05). Interestingly, there was an obvious gender-related difference in PAD patients with T2DM, with the stenosis rate being higher for female than male T2DM patients in the third A-FABP tertile. Logistic regression analysis revealed that serum A-FABP concentrations were an independent risk factor for PAD in female T2DM patients (odds ratio 1.890, 95% confidence interval 1.041-3.432; P = 0.036), but not in male T2DM patients. Correlation analyses revealed that A-FABP concentrations were correlated with body mass index (BMI), diastolic blood pressure, urinary microalbumin, and serum creatinine in male patients, and with BMI, duration of T2DM, fasting blood glucose, and serum creatinine in female patients. CONCLUSIONS Serum A-FABP concentrations are closely associated with PAD in Chinese women with T2DM. The study findings suggest that A-FABP may be a more specific marker of PAD in diabetic women than men.

Abstract
Objective: To monitor the antimicrobial resistance and drug-resistance genes of Yersinia enterocolitis, Y. intermedia and Y. frederiksenii recovered from retailed fresh poultry of 4 provinces of China. Methods: The susceptibility of 25 isolated Yersinia spp. to 14 classes and 25 kinds of antibiotics was determined by broth microdilution method according to CLSI (Clinical and Laboratory Standards Institute). The antibiotic resistance genes were predicted with antibiotic resistance genes database (ARDB) using whole genome sequences of Yersinia spp. Results: In all 22 Y. enterocolitis tested, 63.7% (14 isolates), 22.8% (5 isolates), 4.6% and 4.6% of 1 isolates exhibited the resistance to cefoxitin, ampicillin-sulbactam, nitrofurantoin and trimethoprim-sulfamethoxazole, respectively. All the 25 isolates were multi-drug resistant to more than 3 antibiotics, while 64.0% of isolates were resistant to more than 4 antibiotics. A few Y. enterocolitis isolates of this study were intermediate to ceftriaxone and ciprofloxacin. Most Yersinia spp. isolates contained antibiotic resistance genes mdtG, ksgA, bacA, blaA, rosAB and acrB, and 5 isolates recovered from fresh chicken also contained dfrA1, catB2 and ant3ia. Conclusion: The multi-drug resistant Yersinia spp. isolated from retailed fresh poultry is very serious in the 4 provinces of China, and their contained many kinds of drug-resistance genes.

Abstract
Serum Mac‐2‐binding protein glycosylation isomer (M2BPGi) level was found to be a useful prognostic marker for hepatitis B e antigen (HBeAg)‐positive chronic hepatitis B (CHB) patients treated with nucleoside/nucleotide analogs (NUCs) therapy, and the aim of our study is to evaluate the clinical implementation of M2BPGi level in the prediction of antiviral responses to pegylated‐interferon‐α (PEG‐IFN‐α) treatment in HBeAg‐positive CHB patients. Ninety‐six CHB patients who received PEG‐IFN‐α treatment for at least 48 weeks were recruited. The serum M2BPGi, alanine aminotransferase (ALT), hepatitis B surface antigen (HBsAg), HBeAg, and HBV DNA levels at baseline, weeks 4, 12, and 24 after PEG‐IFN‐α treatment were determined and their associations with antiviral responses were evaluated and the virological response (VR) rate and serological response (SR) rate after 48 weeks of treatment were 65.6% and 35.4%, respectively. Baseline serum M2BPGi level was significantly different between VR and non‐VR (P = 0.002) or SR and non‐SR groups (P = 0.012). Multivariate analyses suggested that baseline serum M2BPGi level was independently associated with VR and SR of PEG‐IFN‐α treatment at week 48. The area under the ROC curve (AUC) of baseline M2BPGi was 0.682 in predicting VR, which was superior to HBsAg (AUC = 0.566) or HBV DNA (AUC = 0.567). The AUC of baseline M2BPGi in predicting SR was 0.655, which was also higher than that of HBsAg (AUC = 0.548) or HBV DNA (AUC = 0.583). These results suggested that baseline serum M2BPGi level was a novel predictor of VR and SR for PEG‐IFN‐α treatment in HBeAg‐positive CHB patients.

Abstract
Objective: To investigate the epidemiological characteristics of waist circumference (WC) and abdominal obesity (AO) among Chinese adults aged 18 and above. Methods: Data were collected from China National Nutrition and Health Surveillance in 2010-2012. Multi-stage stratifies proportion to the population cluster random sampling method was conducted to determine 120 265 subjects aged 18 and above at 150 counties in 31 provinces in China mainland. WC was determined for all subjects, and AO was judged according to the "Healthy Adult Weight Determination" (WS/T 428-2013). Using the demographic data published by the National Bureau of Statistics of China in 2009, we performed complex sampling weighted treatment to calculate the WC, AO rate and 95%CI. Results: The mean WC of Chinese men aged 18 and above was 82.8 cm, which of urban men (84.1 cm) was higher than that of rural men (81.4 cm) (P<0.001). The average WC of women was 78.5 cm. There was no statistical difference between urban (78.7 cm) and rural women (78.4 cm) (P=0.965). With the increase of education level, the mean WC of male increased gradually from 81.2 cm to 84.3 cm (P<0.001), and the mean WC of female decreased from 80.3 cm to 74.3 cm (P<0.001). With the family income rose, the mean WC of men increased gradually from 81.9 cm to 84.7 cm (P<0.001), and the mean of WC of women decreased from 78.8 cm to 77.6 cm (P<0.001). The AO rate was 25.7% (95% CI: 23.7%-27.7%) in adults aged 18 years and older. The AO rate in urban males (29.8% (95%CI: 26.5%-33.1%)) was significantly higher than that of rural males (22.3% (95%CI: 19.3%-25.2%)) (P=0.001). There was no significant difference in the female AO rate between urban (25.6% (95%CI: 22.8%-28.4%)) and rural areas (25.1% (95%CI: 22.2%-27.9%)) (P=0.772). With the increase of the educational level, the AO rate of men increased from 20.1% (95%CI: 18.0%-22.1%) to 32.6% (95%CI: 28.6%-36.6%) (P<0.001), the rate of women decreased gradually from 31.3% (95%CI: 28.7%-33.9%) to 13.5% (95%CI: 10.9%-16.1%) (P<0.001). With the increase of family income, the AO rate of male increased gradually from 23.3% (95%CI: 20.7%-25.9%) to 31.8% (95%CI: 27.6%-36.1%) (P<0.001), the rate of female decreased from 26.5% (95% CI: 24.2%-28.7%) to 20.0% (95% CI: 17.2%-22.8%) (P<0.001). Conclusion: The prevalence of AO among Chinese residents aged 18 years and above was high, and there were significant differences in WC and AO rate between men and women under different age, region, educational level and family income level.

Abstract
Objective: To invesigate the epidemic status of the metabolic syndrome (MS) among mainland Chinese adolescents aged 10-17 in 2010-2012. Methods: Data were collected from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 16 872 adolescents in 150 counties from 31 provinces in mainland China. The epidemic status of metabolic syndrome was analyzed by China criterion (defined by Chinese Pediatric Society, Chinese Medical Association) and Cook criterion, respectively. The prevalence of MS and 95%CI were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009. Results: Based on China criterion, the weighted prevalence of MS was 2.4% (95% CI: 2.1%-2.6%) among Chinese adolescents aged 10-17. Prevalence in urban was higher than in rural (2.8%, 95%CI: 2.4%-3.2% and 1.9%, 95%CI:1.6%-2.3%, respectively). Prevalence in boys and girls were 2.7% (95% CI: 2.3%-3.0%), and 2.0% (95% CI: 1.7%-2.4%), respectively. Based on Cook criterion, the weighted prevalence was 4.3% (95% CI: 4.0%-4.7%) . The highest weighted prevalence of the components of the metabolic syndrome was low high-density lipoprotein cholesterol (26.8%, 95% CI: 26.0%-27.5%), followed by high fasting glucose (11.5%, 95% CI: 11.0%-12.0%), abdominal obesity (11.1%, 95%CI: 10.6%-11.7%) , hypertriglyceridemia (8.8%, 95%CI: 8.4%-9.3%) , and high blood pressure (6.4%, 95% CI: 6.0%-6.8%). Conclusion: Among the five indicators of metabolic syndrome, the prevalence of central obesity and hypertriglyceridemia were relative high in Chinese adolescents aged 10-17 years, though the prevalence of metabolic syndrome was not high.

Abstract
Chronic hepatitis B (CHB) is one of the major public health challenges in the world. Due to a strong interplay between specific T-cell immunity and elimination of hepatitis B virus (HBV), efforts to develop novel immunotherapeutics are gaining attention. TG1050, a novel immunotherapy, has shown efficacy in an animal study. To support the clinical development of TG1050 in China, specific immunity to the fusion antigens of TG1050 was assessed in Chinese patients. One hundred and thirty subjects were divided into three groups as CHB patients, HBV spontaneous resolvers, and CHB patients with HBsAg loss after antiviral treatment. HBV-specific T-cell responses to pools of HBV Core or Polymerase genotype D peptides included in TG1050 were evaluated. HBV Core- or Polymerase-specific cells were detected in peripheral blood mononuclear cells (PBMCs) from the different cohorts. The frequencies and intensities of HBV Core-specific immune responses were significantly lower in CHB patients than in HBsAg loss subjects. In CHB patients, a dominant pool derived from Polymerase (Pol1) was the most immunogenic. CHB patients with low viral loads (<106 IU/mL) were more likely to have a positive response specific to the Core peptide pool. Overall, genotype D-derived peptides included in TG1050 could raise broad and functional T-cell responses in PBMCs from Chinese CHB patients infected with genotype B/C isolates. Core-specific immunogenic domains appeared as "hot spots" with the capacity to differentiate between CHB vs HBsAg loss subjects. These observations support the extended application and associated immune monitoring of TG1050 in China.

Abstract
High serum beta 2 glycoprotein I (β2GPI) is associated with complications of type 2 diabetes mellitus (DM), and especially microvascular disorders. In contrast, reduced β2GPI (Rβ2GPI) can prevent diabetic vascular injury. This study aimed to investigate the protective function of Rβ2GPI in DM vascular disorders, and to assess the under lying mechanisms. High glucose-induced injury in human umbilical vein endothelial cells (HUVECs) was used to model hyperglycemia. Alow concentration of Rβ2GPI (0.5 μM), but not β2GPI, mitigated high glucose-induced cell injury. High glucose decreased miR-21 expression and Akt phosphorylation at 6 h, but facilitated their expression at 48 h. Moreover, high glucose decreased phosphatase and tensin homolog deleted on chromosome ten(PTEN) expression at 6 h, but facilitatedits expression at 48 h. Importantly, by promoting miR-21 expression, Rβ2GPI mitigated high glucose-induced PTEN expression, reduced Akt phosphorylation and nitric oxide synthase activity, and increased cyclooxygenase-2 activity and cell loss. Similar to Rβ2GPI, an miR-21 mimic (1 pM) and PTEN inhibition (1 μM bpV, or PTEN silencing) exerted protective action, while an Akt signaling pathway inhibitor (LY294002, 1 μM) aborted the effect of Rβ2GPI on high glucose-induced cell injury. Finally, Rβ2GPI inhibited high glucose-induced apoptosis via a mitochondria-dependent pathway. These data reveal that Rβ2GPI exerts protective action in high glucose-induced HUVEC injury. The mechanism is related to the miR-21-PTEN-Akt pathway and mitochondria-dependent apoptosis. This study provides in vitro data supporting the therapeutic effect of Rβ2GPI in diabetic vascular injury.

Abstract
Reduced β2 glycoprotein I (β2GPI) has been demonstrated to exhibit a beneficial effect in diabetic atherosclerosis and retinal neovascularization. However, the effect of reduced β2GPI on vascular disorders in diabetic mellitus (DM) remains to be elucidated. The present study established a high glucose‑induced injury model using human umbilical cords veins (HUVECs) and evaluated the protective effects of reduced β2GPI against the injury. The data demonstrated that a low concentration of reduced β2GPI (0.5 µM) mitigated high glucose‑induced cell loss, decreased nitric oxide (NO) production and resulted in calcium overloading. Mechanically, reduced β2GPI additionally reversed high glucose‑induced phosphatase and tensin homolog (PTEN) accumulation, decrease of protein kinase B phosphorylation and nitric oxide synthase activity, and increase of cyclooxygenase‑2 activity. It was further confirmed that PTEN inhibitor‑bpV (1 µM) exhibited similar effects to those resulting from reduced β2GPI. Overall, the data revealed that reduced β2GPI exerts protective effects from glucose‑induced injury in HUVECs, potentially via decreasing PTEN levels. The present study suggests reduced β2GPI may act as a novel therapeutic strategy for the treatment of vascular disorders in DM.

Abstract
BACKGROUND Subclinical hypothyroidism (SCH) is typically featured by elevated serum concentration of thyroid-stimulating hormone (TSH). This study aimed to determine the relationship between TSH levels and microvascular complications in type 2 diabetes patients. MATERIAL AND METHODS A total of 860 type 2 diabetes patients were enrolled in this cross-sectional study. Subjects were evaluated for anthropometric measurements, thyroid function, diabetic retinopathy, and diabetic kidney disease. TSH was divided into 3 levels: 0.27-2.49 mU/l, 2.5-4.2 mU/l, and >4.2 mU/l. RESULTS Among the participants, 76 subjects (8.8%) were diagnosed with subclinical hypothyroidism (SCH) (male: 6.6% and female: 11.8%). The prevalence of diabetic retinopathy did not differ among the groups (P=0.259). Of the 860 type 2 diabetic subjects, we further excluded invalid or missing data. Therefore, 800 and 860 subjects were included in our study of diabetic retinopathy (DR) and diabetic kidney disease (DKD), respectively. The frequencies of microalbuminuria and macroalbuminuria differed significantly among the different groups. The frequency of DKD was significantly different among the 3 groups (P=0.001) and was higher in subjects with higher TSH levels. After an adjustment for confounding variables, TSH levels were significantly associated with DKD (P<0.001). When compared with subjects with TSH 0.27-2.49 mU/l, the frequency of DKD was higher in subjects with TSH >4.20 mU/l (OR 1.531, 95% CI 1.174-1.997) and with TSH 2.50-4.20 mU/l (OR 1.579, 95% CI 1.098-2.270). However, TSH levels was not significantly correlated with DR (P=0.126). CONCLUSIONS Type 2 diabetic patients with higher TSH values had a higher prevalence of DKD.

Abstract
Long noncoding RNA taurine-upregulated gene 1 (lncRNA TUG1) has been reported to play a key role in the progression of diabetic nephropathy (DN). However, the role of lncRNA TUG1 in the regulation of diabetic nephropathy remains largely unknown. The aim of the present study is to identify the regulation of lncRNA TUG1 on extracellular matrix accumulation via mediating microRNA-377 targeting of PPARγ, and investigate the underlying mechanisms in progression of DN. Microarray was performed to screen differentially expressed miRNAs in db/db DN mice. Afterwards, computational prediction programs (TargetScan, miRanda, PicTar and miRGen) was applied to predict the target gene of miRNAs. The complementary binding of miRNA and lncRNA was assessed by luciferase assays. Protein and mRNA expression were detected by western blot and real time quantitate PCR. MiRNA-377 was screened by miRNA microarray and differentially up-regulated in db/db DN mice. PPARγ was predicted to be the target of miR-377 and the prediction was verified by luciferase assays. Expression of miR-377 was up-regulated in mesangial cell treated with high glucose (25 mM), and overexpression of miR-377 inhibited PPARγ expression and promoted PAI-1 and TGF-β1 expression. The expression of TUG1 antagonized the effect of miR-377 on the downregulation of its target PPARγ and inhibited extracellular matrix accumulation, including PAI-1, TGF-β1, fibronectin (FN) and collagen IV (Col IV), induced by high glucose. LncRNA TUG1 acts as an endogenous sponge of miR-377 and downregulates miR-377 expression levels, and thereby relieving the inhibition of its target gene PPARγ and alleviates extracellular matrix accumulation of mesangial cells, which provides a novel insight of diabetic nephropathy pathogenesis.

Abstract
Dipeptidyl peptidase-4 inhibitors, such as saxagliptin, have been reported to have beneficial effects on β-cell function, but the specific underlying mechanism remains unclear. Stromal cell-derived factor-1α (SDF-1α), a chemokine produced in multiple organs, has been considered as a crucial regulator in promoting β-cell survival. Here, we speculate that SDF-1α might mediate the effect of saxagliptin on improving β-cell function. After 12-week saxagliptin treatment in high-fat diet/streptozotocin-induced diabetic rats, significant improvement in pancreas insulin secretion capacity evaluated by hyperglycemia clamp and increased β-cell to α-cell areas ratio were observed. Saxagliptin significantly induced β-cell proliferation and upregulated the expression of proliferation-related factors including c-myc and cyclind D1 determined with western blotting from the isolated islets. The expression/activity of DPP-4 was significantly reduced and paralleled with the restoration of SDF-1α levels in the saxagliptin-treated diabetic rats, subsequently the key WNT-signaling regulators, β-catenin, and AKT were activated. However, the effect of saxagliptin inducing β-cell proliferation was attenuated when we silenced the SDF-1α receptor (CXCR4) with RNAi in INS cell lines. Collectively, our data indicate that SDF-1α mediates the protective effect of saxagliptin on β-cell proliferation, suggesting that DPP-4 inhibitors have the potential role on delaying β-cell failure and SDF-1α could be a therapeutic target of β-cell regeneration.

Abstract
BACKGROUND & AIMS Accurate evaluation of liver fibrosis is crucial for predicting progression of chronic hepatitis B virus (HBV) infection. We assessed the utility of a novel fibrosis glycobiomarker Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA+ -M2BP) for evaluating liver fibrosis and disease progression in patients with chronic HBV infection. METHODS We enrolled 774 patients with chronic HBV infection, with or without fibrosis, diagnosed by liver biopsy/FibroScan. Patients who underwent liver biopsy (n = 297) were divided into training (n = 221) and validation (n = 76) groups. Serum WFA+ -M2BP values were measured and compared with FIB-4 index, aspartate aminotransferase (AST)-to-platelet ratio (APRI) and AST-to-alanine aminotransferase ratio (AAR) using receiver-operating characteristic (ROC) analysis. RESULTS Serum WFA+ -M2BP levels increased significantly with fibrosis progression (P < 0.0001). Area under the ROC curve of WFA+ -M2BP for diagnosing significant fibrosis was higher than that of FIB-4 (P = 0.198), APRI (P = 0.017) and AAR (P < 0.001), with sensitivity and specificity in the training set of 60.5% and 79.8% and validation set of 59.5% and 82.1%, respectively. Serum WFA+ -M2BP levels were significantly correlated with FibroScan values (P < 0.0001) and improved the accuracy of FibroScan in assessing significant fibrosis. Changes in WFA+ -M2BP levels were parallel with those in FibroScan values during nucleot(s)ide analogues therapy in patients with chronic HBV infection. CONCLUSIONS WFA+ -M2BP is an accurate serum indicator for assessing early stages of liver fibrosis and may monitor regression of fibrosis during the treatment of chronic HBV infection. WFA+ -M2BP provides a simple and reliable alternative or complementary method to liver biopsy and FibroScan.

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
BACKGROUND CpG islands in hepatitis B virus (HBV) genome are potential targets for methylation mediated gene silencing, and may be involved in the pathogenesis of HBV infection. To date, their characteristics in HBV quasispecies (QS) remain largely unknown. The purpose of this study was to investigate the characteristics of CpG islands in HBV QS. METHODS Forty patients diagnosed as acute hepatitis B (AHB, n = 10), immune-tolerant HBV carriers (IT, n = 9), chronic hepatitis B (CHB, n = 11), or acute on chronic liver failure (ACLF, n = 10), were enrolled in this case-control study. A total of 599 clones were isolated, and full-length HBV genomes were sequenced. RESULTS CpG island II (CGII) in AHB group was shorter in length and its QS heterogeneity was lower than that in the chronic infection group. Among the chronic infection subgroups, CGII and CpG island III (CGIII) in IT group were longer and their heterogeneity was lower compared to CHB and ACLF groups. Length of CGII correlated with HBV DNA levels positively while the complexity and diversity of CGII correlated with HBV DNA levels negatively. Moreover, CGII and CGIII were shorter in genotype B than those in genotype C, while QS complexity and diversity of either CGII or CGIII had no significant difference between genotype B and C. CONCLUSIONS Overall, our results suggest that the distribution, length and QS heterogeneity of CpG islands in full-length HBV genome differ across clinical phases of infection, of which the mechanism warrants further study.

Abstract
Oxidized low-density lipoprotein (oxLDL) can bind to β2-glycoprotein I (β2GPI) and C-reactive protein (CRP) to form stable complexes, which exert certain effects in diabetic cardiovascular disease. A previous study by our group has confirmed that the resulting complexes promote atherosclerosis in diabetic BALB/c mice. The present study was designed to investigate the effects and potential mechanisms of oxLDL complexes on lipid accumulation and inflammatory reactions in RAW264.7 macrophages cultured in a hyperglycemic environment. Cultured cells were divided into seven groups, which were treated with phosphate‑buffered saline (control), CRP, β2GPI, oxLDL, CRP/oxLDL, oxLDL/β2GPI or CRP/oxLDL/β2GPI. The results revealed the formation of foam cells in the oxLDL, CRP/oxLDL, oxLDL/β2GPI as well as CRP/oxLDL/β2GPI groups. Compared with oxLDL, the three complexes induced less lipid accumulation (P<0.05) through inhibiting the expression of CD36 mRNA and promoting the expression of and ABCG1 mRNA (P<0.05 vs. oxLDL). Furthermore, the levels of inflammatory factors interleukin (IL)‑1β, IL‑6 and tumor necrosis factor‑α were elevated in the CRP/oxLDL and CRP/oxLDL/β2GPI groups (P>0.05 vs. oxLDL), and obvious effects on p38/mitogen‑activated protein kinase and nuclear factor (NF)‑κB phosphorylation were also observed in these groups (P<0.05 vs. oxLDL). These results suggested that CRP/oxLDL/βG2P1 complexes may induce lipid accumulation and inflammation in macrophages via the p38/MAPK and NF‑κB signaling pathways. However, some differences were observed between the complexes, which may be attributed to the property of each constituent; therefore, further studies are required.

Abstract
Type 2 diabetes mellitus induced atherosclerosis (DA) is regarded as a major cause of disability and death in diabetic patients. The early prediction of atherosclerosis in patients DM is necessary. Therefore, we aimed to identify special plasma microRNAs that can serve as a novel non-invasive screening signature of DA patients with atherosclerosis and test its specificity and sensitivity in the early diagnosis of DA. In total, we obtained plasma samples from 285 diabetic atherosclerosis patients and matched diabetic retinopathy (DR) patients, diabetic nephropathy (DN) patients, diabetes mellitus without complication (DM) and healthy controls. An initial screening of miRNA expression was performed through TaqMan Low Density Array (TLDA). Three miRNAs were significantly increased in patients with DA compared with other groups after the multiple stages. The areas under the receiver operating characteristic (AUC) curves of the validated three-plasma miRNAs signature in DA comparing with NC were 0.881, 0.709 and 0.842 while the merged was 0.940 while DA comparing with DM was 0.879, 0.663, 0.731 and the merged was 0.928. The three miRNA could also distinguish DA from DN with an AUC of 0.894, 0.782, 0.910 and 0.963 (merged) as well as from DR with an AUC of 0.876, 0.815, 0.850 and 0.925 (merged). In conclusion, these data provide evidence that plasma miRNAs have the potential to be sensitive, cost-effective biomarkers for the early detection of DA. These biomarkers could serve as a dynamic monitoring factor for detecting the progression of DA from DR, DN, DM patients.

Abstract
LIM domain kinase 1 (LIMK1), an actin-binding kinase, can phosphorylate and inactivate its substrates, and can regulate long-term memory and synaptic plasticity. Both β-amyloid precursor protein (App) and presenilin (PS) are functional degeneration factors during early neuronal development, and are considered as potential factors that contribute to the development of Alzheimer's disease (AD). However, hardly any information is available about the distribution and expression of LIMK1. Thus, using the App and PS deficient mice, the role of LIMK1 was demonstrated in the absence of App and PS. Our results showed that LIMK1 was present in the nerve fiber layer and external plexiform layer of the olfactory bulb, as well as in the mitral cells and Purkinje cells of the cerebellum in App and PS deficient mice. Additionally, LIMK1 was concentrated in the granule cell layer of the olfactory bulb and cerebellum and LIMK1 positive cells were located in the CA1 region of the hippocampus. Our study indicates that there is a connection between LIMK1 and AD in the mouse model of AD. This might explain neurological problems such as cerebellar ataxia, impaired long-term memory, and impaired synaptic plasticity observed in AD.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is frequently seen in the type 2 diabetes mellitus (T2DM) population. Insulin resistance is the pathophysiologic bridge which links T2DM and NAFLD. Coexistence of both diseases indicates more severe diseases and higher risk of death. As a result, it is urgent to effectively control NAFLD in patients with T2DM. The advent of glucagon like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors brings new hope for effectively managing NAFLD in T2DM patients. Bariatric surgery provides obese T2DM patients with a powerful means to treat NAFLD. The discovery of adipokines such as adiponectin and fibroblast growth factor 21 (FGF21) may point to a new research direction for NAFLD. In this paper, we present therapeutic options currently available for NAFLD in T2DM patients as well as the present research progress in NAFLD with T2DM, with regards to epidemiology and pathophysiologic links between them.

Abstract
BACKGROUND The best strategy for chronic hepatitis B patients with poor response to 48 weeks of Peginterferon-based therapy has been controversial and the predictive value of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA levels for determining the sustained virological response (SVR) of these patients is uncertain. OBJECTIVES To optimize management of these patients and evaluate the use of these serobiomarkers to predict SVR. STUDY DESIGN Eighty-one patients with an unsatisfactory response after 48 weeks of Peginterferon-based therapy were treated with extended Peginterferon therapy with or without nucleo(s) tide analogues (NAs), for a total of 96 weeks of Peginterferon treatment. HBsAg, HBeAg and HBV DNA levels were measured serially during the treatment and follow-up. RESULTS AND CONCLUSIONS Twenty-six of 81 patients (32.1%) attained SVR during the 72-week follow-up. The SVR rate was not statistically different between groups receiving 1-year prolongation of Peginterferon with or without NAs. The serum HBsAg cut-off of 1800IU/mL at week 48 had area under curve (AUC) of 0.727, and the serum HBsAg cut-off of 1500IU/mL, combined with HBeAg loss at week 72, had AUC of 0.753 to predict SVR during the follow-up. In conclusion, extended treatment with Peginterferon with or without NAs for patients with unsatisfactory response after 48 weeks of Peginterferon-based therapy is a promising strategy to achieve SVR, and quantitative serum HBsAg at week 48 and HBsAg level combined with HBeAg loss at week 72 of therapy can predict SVR to prolongation therapy with Peginterferon.

Abstract
We aimed to observe the effect of penehyclidine hydrochloride (PHC) on lipopolysaccharide (LPS)-induced acute kidney injury in rats and expression of tight junction proteins ZO-1 and occludin. Adult male Sprague-Dawley (SD) rats were divided randomly (N = 10) into control group (C), LPS group (LPS), low-dose PHC group (L-PHC), and high-dose PHC group (H-PHC). All rats, except C group, received a vena caudalis injection of 5.0 mg/kg LPS; after 30 min, rats in L-PHC and H-PHC groups received a vena caudalis injection of 0.3 and 0.9 mg/kg PHC. After 24 h, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, serum creatinine (Scr), and blood urea nitrogen (BUN) were detected. Histopathological changes and expression of ZO-1 and occludin were observed in renal tissues. Versus levels of TNF-α (38.5 ± 9.0), IL-1β (46.3 ± 12.7), Scr (37.2 ± 9.3), and BUN (6.5 ± 1.1) in control group, those in LPS group, TNF-α (159.0 ± 21.3), IL-1β (130.8 ± 18.7), Scr (98.5 ± 18.2), and BUN (12.8 ± 1.8), increased obviously (P < 0.05), with significantly structural changes and decreases of ZO-1 and occludin. However, TNF-α (111.3 ± 11.6), IL-1β (78.4 ± 14.3), Scr (51.3 ± 12.5), BUN (8.1 ± 1.2) in H-PHC group, and TNF-α (120.8 ± 14.3), IL-1β (92.5 ± 19.0), Scr (56.7 ± 14.7), BUN (9.7 ± 1.6) in L-PHC group were obviously decreased (P < 0.05). PHC has protective effects on acute kidney injury in sepsis, including abatement of renal tissue inflammation and functional improvement, potentially by upregulating ZO-1 and occludin.

Abstract
PURPOSE Beta 2 glycoprotein I (β2GPI) has been shown the positive effect on diabetic atherosclerosis and retinal neovascularization. β2GPI can be reduced by thioredoxin-1, resulting in the reduced state of β2GPI. The possible protective effects of β2GPI and reduced β2GPI on diabetic nephropathy (DN) are not fully elucidated. The purpose of this study was to test a hypothesis that β2GPI and reduced β2GPI would improve DN in streptozotocin (STZ) induced diabetic mice and high-glucose (HG) exposed rat mesangial cell (RMC). METHODS The STZ-induced Balb/c mice and HG exposed RMCs were administrated with β2-GPI and reduced β2-GPI at different time and concentrations gradient respectively. The changes of glomerular structure and expression of collagen IV, TGF-β1, p38 MAPK and phospho-p38 MAPK in renal cortical and mesangial cells were observed by immunohistochemical techniques, quantitative real-time PCR and western blot with or without the treatment of β2-GPI and reduced β2-GPI. RESULTS β2GPI and reduced β2GPI improved early clinical and pathological changes of DN in STZ-diabetic mice. Treatment with β2GPI and reduced β2GPI in the STZ-diabetic mice and HG exposed RMCs resulted in decrease expression levels of TGF-β1 and collagen IV, with concomitant decrease in phospho-p38 MAPK expression. CONCLUSIONS β2GPI and reduced β2GPI improved renal structural damage and kidney function. The renoprotective and antifibrosis effects of β2GPI and reduced β2GPI on DN were closely associated with suppressing the activation of the TGF-β1-p38 MAPK pathway.

Abstract
AIMS Macro-nutrient preloads given 30 min before regular meals may improve metabolism. The aim was to investigate how type 2 diabetic patients react to a preload consisting of a blend of macro-nutrients with a low-glycemic index (Inzone Preload(®)). METHODS In a before-after study design, 30 subjects with type 2 diabetes mellitus (T2DM) were enrolled in a 12-week program. All subjects were given Inzone Preload (43% proteins, 29% carbohydrates, 10% lipids, and 9% fibers, 71 kcal), 30 min before each meal during 12 weeks. Fasting glucose and postprandial 2 h glucose were monitored every second week. Body weight (BW) and waist circumference were measured each month. Fasting plasma glucose, glycosylated hemoglobin, serum lipids, fasting insulin, C-reactive protein, and homeostasis model assessment were evaluated before and after the intervention. Subjective appetite was monitored using visual analogue scales after the Inzone Preload. RESULTS The dietary intervention significantly influenced several metabolic parameters compared to base line. Inzone Preload treatment reduced mean postprandial plasma glucose levels (12.2 ± 1.2 vs. 10.5 ± 2.0 mmol/L), HbA1c (7.4 ± 0.3 vs. 7.1 ± 0.2%), mean total cholesterol (4.8 ± 0.9 vs. 4.3 ± 0.8 mmol/L), low-density lipoprotein cholesterol (2.8 ± 0.6 vs. 2.5 ± 0.4 mmol/L), and CRP (1.5 ± 1.4 vs. 0.7 ± 0.7 mg/L). BW loss of more than 3% was seen in 13 participants (43%). Feelings of satiety were significantly higher after Inzone Preload than after habitual breakfast (p < 0.05). No significant changes in fasting blood glucose, high-density lipoprotein and total triacylglycerol, HOMA-IR, and HOMA-β were observed. CONCLUSION A macro-nutrient preload treatment reduces postprandial glucose, inflammatory markers, and serum lipids in patients with T2DM. Approximately half of the study group also displayed reduced BW.

Abstract
We studied two patients from a nonconsanguineous family with life-long abnormal liver function, hepatomegaly and abnormal fatty acid profiles. Abnormal liver function, hypoglycemia and muscle weakness are observed in various genetic diseases, including medium-chain acyl-CoA dehydrogenase (MCAD) deficiency and glycogen storage diseases. The proband showed increased free fatty acids, mainly C8 and C10, resembling fatty acid oxidation disorder. However, no mutation was found in ACADM and ACADL gene. Sequencing of theamylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase (AGL) gene showed that both patients were compound heterozygotes for c.118C > T (p.Gln40X) and c.753_756 del CAGA (p.Asp251Glufsx29), whereas their parents were each heterozygous for one of these mutations. The AGL protein was undetectable in EBV-B cells from the two patients. Transcriptome analysis demonstrated a significant different pattern of gene expression in both of patients’ cells, including genes involving in the PPAR signaling pathway, fatty acid biosynthesis, lipid synthesis and visceral fat deposition and metabolic syndrome. This unique gene expression pattern is probably due to the absence of AGL, which potentially accounts for the observed clinical phenotypes of hyperlipidemia and hepatocyte steatosis in glycogen storage disease type IIIa.

Abstract
BACKGROUND To observe the efficacy and safety of adding glimepiride to established insulin therapy in poorly controlled type 2 diabetes (T2D) and to assess the relationship of changes in the serum high-molecular weight (HMW) adiponectin levels and glycemic control after glimepiride treatment. METHODS Fifty-six subjects with poorly controlled insulin-treated T2D were randomly assigned to either the glimepiride-added group (the group A, n = 29) or the insulin-increasing group (the group B, n = 27) while continuing current insulin-based therapy. Glycosylated hemoglobin (HbA1c) value, daily insulin dose, body weight, waist circumference, plasma lipid concentration, serum HMW adiponectin level and the number of hypoglycemic events were evaluated before and after treatment. RESULTS At the end of study, insulin doses were significantly reduced, and the mean HbA1c, fasting blood glucose (FBG) and 2-hour postprandial blood glucose (P2BG) were improved greater in the group A compared with the group B. The serum HMW adiponectin levels were significantly increased in the group A compared with the group B. Most importantly, we found that changes in HbA1c were inversely correlated with changes in serum HMW adiponectin in the group A (r = -0.452, p = 0.02). CONCLUSIONS Adding glimepiride to current insulin treatment led to better improvement in glycemic control with a significant smaller daily insulin dose, and the increases in the serum HMW adiponectin levels may directly contribute to improvement glycemic control.

Abstract
BACKGROUND & AIMS HBV immune escape represents a challenge to prevention, diagnosis, and treatment of hepatitis B. Here, we analyzed the molecular and clinical characteristics of HBV immune escape mutants in a Chinese cohort of chronically infected patients. METHODS Two hundred sixteen patients with HBsAg and anti-HBs were studied, with one hundred eighty-two HBV carriers without anti-HBs as a control group. Recombinant HBsAg bearing the most frequent N-glycosylation mutations were expressed in CHO and HuH7 cells. After confirming N-glycosylation at the most frequent sites (129 and 131), together with inserted mutations, functional analysis were performed to study antigenicity and secretion capacity. RESULTS One hundred twenty-three patients had the wild-type HBs gene sequence, 93 patients (43%) had mutants in the major hydrophilic region (MHR), and 47 of the 93 patients had additional N-glycosylation mutations, which were transmitted horizontally to at least 2 patients, one of whom was efficiently vaccinated. The frequency of N-glycosylation mutation in the case group was much higher than that of the control group (47/216 vs. 1/182). Compared with wild-type HBsAg, HBsAg mutants reacted weakly with anti-HBs using a chemiluminescent microparticle enzyme immunoassay. Native gel analysis of secreted virion in supernatants of transfected HuH7 cells indicated that mutants had better virion enveloping and secretion capacity than wild-type HBV. CONCLUSIONS Our results suggest that specific HBsAg MHR N-glycosylation mutations are implicated in HBV immune escape in a high endemic area.

Abstract
Background and aims Liraglutide treatment can improve glycemic control with a concomitant weight loss, but the underlying mechanism on weight loss is not completely understood. Cardiac natriuretic peptides (NPs) can resist body fat accumulation through increasing adipocytes lypolysis. In this study, we tested the hypothesis that liraglutide-induced weight loss was associated with increased plasma NPs concentrations. Methods Thirty-one outpatients with type 2 diabetes (T2D) treated with metformin and other oral antidiabetic drugs except for thiazolidinediones (TZDs) were subcutaneously administered with liraglutide for 12 weeks. Body composition, abdominal visceral adipose tissue areas (VAT) and subcutaneous adipose tissue areas (SAT) were assessed at pre- and post-treatment by dual-energy X-ray absorptiometry (DXA) scanning and abdominal computerized tomography (CT). Plasma atrial natriuretic peptides (ANP) and B-type ventricular natriuretic peptides (BNP) concentrations were tested by commercial ELISA Kit quantitatively. Results Following 12-week liraglutide treatment, body weight, waist circumference, total fat and lean mass, fat percentage, SAT and VAT areas were significantly reduced from baseline. Concurrently, plasma ANP and BNP levels were significantly increased following 12-week liraglutide treatment. There were significant correlations between the reductions in body compositions and the increases in both plasma ANP and BNP levels. Conclusions There were significant correlations between increases in both plasma ANP and BNP levels and changes in liraglutide-induced body composition. Our data implied that increases in plasma NPs may add a novel dimension to explain how liraglutide induces weight loss.

Abstract
BACKGROUND The oral DPP-4 inhibitors are new incretin-based therapies for treatment of type 2 diabetes. To assess the efficacy and safety of three DPP-4 inhibitors (Saxagliptin, Sitagliptin and Vildagliptin) as add-on therapy to dual combination of traditional oral hypoglycemic agents in Chinese type 2 diabetes patients. METHODS In this 24-week, randomized, open-label, parallel clinical trial, we enrolled inadequately controlled (glycosylated haemoglobin A1c [HbA1c] ≥7.5% to ≤10%) patients with type 2 diabetes, who were treated by dual combination of metformin and another traditional oral hypoglycemic agent (glimepiride, acarbose or pioglitazone). 207 patients had been randomized to add-on 5 mg saxagliptin group or 100 mg sitagliptin once daily group, or 50 mg vildagliptin twice daily group for 24 weeks. HbA1c, fasting and postprandial blood glucose (FBG and P2hBG), body weight, body mass index (BMI), episodes of hypoglycemia and adverse events were evaluated. RESULT After 24 weeks, HbA1c, FBG, and P2hBG of each group were significantly decreased. (saxagliptin vs vildagliptin vs sitagliptin: HbA1c: -1.2% vs -1.3% vs -1.1%; FBG: -1.8 mmol/l vs -2.4 mmol/l vs -1.5 mmol/l; P2hBG: -3.4 mmol/l vs -3.7 mmol/l vs -3.2 mmol/l). The changes of HbA1c and P2hBG among the three groups had no significance. However, vildagliptin-added group showed the greatest reduction (p < 0.001), while, sitagliptin-added group showed the lowest reduction (p < 0.001) in terms of FPG changes. Proportions of patients achieving HbA1c < 7% at the end were similar in three groups (saxagliptin 59%, vildagliptin 65%, sitagliptin 59%). Mild hypoglycemia was commonly reported among the three groups (saxagliptin 6%, vildagliptin 2%, sitagliptin 3%). No significant between-group difference was shown in other AEs. CONCLUSION The three gliptins showed almost similar glycemic control and incidence of adverse events. However, for FBG control, saxagliptin demonstrated superiority to sitagliptin, while, inferiority to vildagliptin.

Abstract
We previously reported that, based on clone-based sequencing (CBS), hepatitis B virus (HBV) heterogeneity within the reverse transcriptase (RT) region was a predictor of antiviral efficacy. Here, by comparing ultradeep pyrosequencing (UDPS), i.e., next-generation sequencing (NGS), with CBS in characterizing the genetic heterogeneity of HBV quasispecies within the RT region, we evaluated the performance of UDPS in the analysis of HBV viral populations. HBV genomic DNA was extracted from serum samples from 31 antiviral treatment-naive patients with chronic hepatitis B. The RT region quasispecies were analyzed in parallel using CBS and UDPS. Characterization of quasispecies heterogeneity was conducted using bioinformatics analysis. Quasispecies complexity values were calculated with the formula Sn = -Σi(pilnpi)/lnN. The number of qualified strains obtained by UDPS was much larger than that obtained by CBS (P < 0.001). Pearson analysis showed that there was a positive correlation of quasispecies complexity values at the nucleotide level for the two methods (P < 0.05), while the complexity value derived from UDPS data was higher than that derived from CBS data (P < 0.001). Study of the prevalences of variations within the RT region showed that CBS detected an average of 9.7 ± 1.1 amino acid substitutions/sample and UDPS detected an average of 16.2 ± 1.4 amino acid substitutions/sample. The phylogenetic analysis based on UDPS data showed more genetic entities than did that based on CBS data. Viral heterogeneity determination by the UDPS technique is more sensitive and efficient in terms of low-abundance variation detection and quasispecies simulation than that by the CBS method, although imperfect, and thus sheds light on the future clinical application of NGS in HBV quasispecies studies.

Abstract
Background Reduced beta2-glycoprotein I (beta2-GPI) is a free thiol-containing form of beta2-GPI that displays a powerful effect in protecting endothelial cells from oxidative stress-induced cell death. The present study aims to investigate the effect of beta2-GPI or reduced beta2-GPI on ox-LDL-induced foam cell formation and on cell apoptosis and to determine the possible mechanisms. Methods The RAW264.7 macrophage cell line was selected as the experimental material. Oil red O staining and cholesterol measurement were used to detect cholesterol accumulation qualitatively and quantitatively, respectively. Flow cytometry was used to detect cell apoptosis. Real-time quantitative PCR was used to detect the mRNA expression of the main proteins that are associated with the transport of cholesterol, such as CD36, SRB1, ABCA1 and ABCG1. Western blot analysis was used to detect the protein expression of certain apoptosis-related proteins, such as caspase-9, caspase-3, p38 MAPK/p-p38 MAPK and JNK/p-JNK. Results Beta2-GPI or reduced beta2-GPI decreased ox-LDL-induced cholesterol accumulation (96.45 ± 8.51 μg/mg protein vs. 114.35 ± 10.38 μg/mg protein, p < 0.05;74.44 ± 5.27 μg/mg protein vs. 114.35 ± 10.38 μg/mg protein, p < 0.01) and cell apoptosis (30.00 ± 5.10% vs. 38.70 ± 7.76%, p < 0.05; 20.66 ± 2.50% vs. 38.70 ± 7.76%, p < 0.01), and there are significant differences between beta2-GPI and reduced beta2-GPI (p < 0.05). Reduced beta2-GPI decreased the ox-LDL-induced expression of CD36 mRNA and ABCA1 mRNA (p < 0.05), as well as CD36, cleaved caspase-9, cleaved caspase-3, p-p38 MAPK and p-JNK proteins (p < 0.05 or p < 0.01). Beta2-GPI did not significantly decrease the expression of ABCA1 mRNA and the p-p38 MAPK protein. Conclusions Both beta2-GPI and reduced beta2-GPI inhibit ox-LDL-induced foam cell formation and cell apoptosis, and the latter exhibits a stronger inhibition effect. Both of these glycoproteins reduce the lipid intake of macrophages by downregulating CD36 as well as protein expression. Reduced beta2-GPI inhibits cell apoptosis by reducing the ox-LDL-induced phosphorylation of p38 MAPK and JNK, and the amount of cleaved caspase-3 and caspase-9. Beta2-GPI does not inhibit the ox-LDL-induced phosphorylation of p38 MAPK.

Abstract
BACKGROUND The prevalence of type 2 diabetes mellitus (T2DM) is increasing rapidly among Chinese adults, and limited data are available on T2DM management and the status of glycemic control in China. We assessed the efficacy of oral antidiabetes drugs (OADs), glucagon-like peptide-1 (GLP-1) receptor agonists, and insulin for treatment of T2DM across multiple regions in China. METHODS This was a multicenter, cross-sectional survey of outpatients conducted in 606 hospitals across China. Data from all the patients were collected between April and June, 2011. RESULTS A total of 238,639 patients were included in the survey. Eligible patients were treated with either OADs alone (n=157,212 [65.88%]), OADs plus insulin (n=80,973 [33.93%]), or OADs plus GLP-1 receptor agonists (n=454 [0.19%]). The OAD monotherapy, OAD + insulin, and OAD + GLP-1 receptor agonist groups had mean glycosylated hemoglobin (HbA1c) levels (±SD) of 7.67% (±1.58%), 8.21% (±1.91%), and 7.80% (±1.76%), respectively. Among those three groups, 34.63%, 26.21%, and 36.12% met the goal of HbA1c <7.0%, respectively. Mean HbA1c and achievement of A1c <7.0% was related to the duration of T2DM. CONCLUSIONS Less than one third of the patients had achieved the goal of HbA1c <7.0%. Glycemic control decreased and insulin use increased with the duration of diabetes.

Abstract
Background The aim of this study was to investigate the effect of C-reactive protein/oxidised low-density lipoprotein/β2-glycoprotein I (CRP/oxLDL/β2GPI) complex on atherosclerosis (AS) in diabetic BALB/c mice. Methods BALB/c mice were fed high-fat and normal diet. Eight weeks later, the mice fed with high-fat diet were injected with streptozotocin (STZ) to induce diabetes. The diabetic mice were respectively injected twice monthly with 20 μg oxLDL, 20 μg β2GPI, 40 μg oxLDL/β2GPI complex, 44 μg CRP/oxLDL/β2GPI complex, and PBS. Aortas were stained with Sudan IV to investigate lipid plaque formation. The infiltration condition of smooth muscle cells (SMCs), macrophages, and T cells in the aortas were determined by immunohistochemistry (IH). The mRNA expressions of receptors associated with lipid metabolism were quantified by real-time PCR. The phosphorylation of p38 mitogen-activated protein kinase (p38MAPK) and MKK3/6 in aorta tissues were assessed by Western blot. The expression of inflammation cytokines was evaluated by protein chip. Results The lipid plaques were more extensive, the lumen area was obviously narrower, the ratio of intima and media thickness were increased, and the normal internal elastic lamia structure and endothelial cell disappeared (P < 0.05) in the oxLDL and CRP/oxLDL/β2GPI groups (P < 0.05). CRP/oxLDL/β2GPI complex dramatically promoted infiltration of SMCs, macrophages, and T cells, improved the mRNA expression of ABCA1 and ABCG1, but reduced the mRNA expression of SR-BI and CD36 and increased the phosphorylation of p38MAPK and MKK3/6 (all P < 0.05). The highest expression levels of IL-1, IL-9, PF-4, bFGF, and IGF-II were detected in the CRP/oxLDL/β2GPI group (P < 0.05). Conclusions CRP/oxLDL/β2GPI complex aggravated AS in diabetic BALB/c mice by increasing lipid uptake, the mechanism of which may be mediated by the p38MAPK signal pathway.

Abstract
Objective Beta-2-glycoprotein I (β2GPI) constitutes the major autoantigen in the antiphospholipid syndrome (APS), a common acquired cause of arterial and venous thrombosis. We recently described the novel observation that β2GPI may exist in healthy individuals in a free thiol (biochemically reduced) form. The present study was undertaken to quantify the levels of total, reduced, and posttranslationally modified oxidized β2GPI in APS patients compared to various control groups. Methods In a retrospective multicenter analysis, the proportion of β2GPI with free thiols in serum from healthy volunteers was quantified. Assays for measurement of reduced as well as total circulating β2GPI were developed and tested in the following groups: APS (with thrombosis) (n = 139), autoimmune disease with or without persistent antiphospholipid antibodies (aPL) but without APS (n = 188), vascular thrombosis without APS or aPL (n = 38), and healthy volunteers (n = 91). Results Total β2GPI was significantly elevated in patients with APS (median 216.2 μg/ml [interquartile range 173.3–263.8]) as compared to healthy subjects (median 178.4 μg/ml [interquartile range 149.4–227.5] [P < 0.0002]) or control patients with autoimmune disease or vascular thrombosis (both P < 0.0001). The proportion of total β2GPI in an oxidized form (i.e., lacking free thiols) was significantly greater in the APS group than in each of the 3 control groups (all P < 0.0001). Conclusion This large retrospective multicenter study shows that posttranslational modification of β2GPI via thiol-exchange reactions is a highly specific phenomenon in the setting of APS thrombosis. Quantification of posttranslational modifications of β2GPI in conjunction with standard laboratory tests for APS may offer the potential to more accurately predict the risk of occurrence of a thrombotic event in the setting of APS.

Abstract
OBJECTIVE To investigate the evolution of hepatitis B virus (HBV) quasispecies (QS) within the reverse transcriptase (RT) region during the early stage of entecavir treatment and its impact on virological response, and to compare evolutionary patterns under different selective pressures. METHODS 31 patients with chronic hepatitis B receiving entecavir (17 responders and 14 partial responders according to the HBV DNA levels at week 48) and 25 patients receiving lamivudine (14 responders and 11 non-responders) as controls were included. An average of 26 clones (2892 total from both groups) spanning the RT region per sample was sequenced. RESULTS QS complexity and diversity, in addition to alanine aminotransferase and HBV DNA levels, were comparable between responders and partial responders at baseline. However, QS complexity in responders at week 4 was statistically lower than that in partial responders at the nucleotide level (0.6494 vs. 0.7723, p=0.039). Net changes in diversity as well as the viral nucleotide substitution rate of responders were higher than those of partial responders, and both correlated with virological responses at both week 48 and the final visit (mean: 28 months). A preliminary model of QS evolution variables predicted 16 of 17 responders and 13 of 14 partial responders in the entecavir group. Despite significant differences between responders to entecavir and responders to lamivudine at week 4, the characteristics of QS were quite similar between partial responders to entecavir and non-responders to lamivudine. CONCLUSIONS The evolutionary patterns of HBV RT QS differ between responders and partial responders during the early stage of entecavir treatment. Characteristics of HBV QS evolution during the first 4 weeks contribute to the prediction of long-term virological responses. The similar patterns of HBV RT QS in partial responders and non-responders receiving different nucleoside analogues may imply a novel mechanism of drug resistance, which warrants further investigation.

Abstract
OBJECTIVE To study the role of S6K1 in the induction of SREBP1c in mouse hepatic cell by high glucose stimulation. METHODS S6K1 shRNA recombinant adenovirus (S6K1Ax) was injected into tail vein of db/db mice and then hepatic triglycerol content was analyzed. Liver specimen were stained with HE. After transfection with S6K1Ax or pU6Ax, mouse hepatic AML12 cells were treated with high glucose, insulin or glucose and insulin, the expression of mSREBP1c was detected by RT-PCR. S6K1 protein was detected by Western blot. RESULTS Hepatic S6K1 protein in db/db mice was inhibited a week after S6K1Ax injection. Compared with the control group, hepatic triglycerol content of S6K1Ax group was decreased (0.65+/-0.02) mmol/L vs (0.56+/-0.01) mmol/L (t = 4.312, P less than 0.01), hepatocyte fat droplet and vaculor generation were also decreased, fatty liver was improved. The mSREBP1c expression in S6K1Ax transfected cells was lower than that in the control cells (0.03+/-0.01 vs 0.06+/-0.01, t = 5.624, P less than 0.01). Compared with the basal state, SREBP1c expression of both groups was increased on the insulin stimulation, S6K1Ax group was 0.06+/-0.02 (t = 8.452, P less than 0.01) and control group was 0.08+/-0.02 (t = 3.591, P less than 0.05). There is no difference between control and S6K1Ax group by glucose addition (P more than 0.05). CONCLUSION S6K1 acts on fatty synthesis by regulating mSREBP1c expression.
