Abstract
The recognition of food images is of great significance for nutrition monitoring, food retrieval and food recommendation. However, the accuracy of recognition had not been high enough due to the complex background of food images and the characteristics of small inter-class differences and large intra-class differences. To solve these problems, this paper proposed a food image recognition method based on transfer learning and ensemble learning. Firstly, generic image features were extracted by using the convolutional neural network models (VGG19, ResNet50, MobileNet V2, AlexNet) pre-trained on the ImageNet dataset. Secondly, the 4 pre-trained models were transferred to the food image dataset for model fine-tuning. Finally, different basic learner combination strategies were adopted to establish the ensemble model and classify feature information. In this paper, several kinds of experiments were performed to compare the results of food image recognition between single models and ensemble models on food-11 dataset. The experimental results demonstrated that the accuracy of the ensemble model was the highest, reaching 96.88%, which was superior to any base learner. Therefore, the convolutional neural network model based on transfer learning and ensemble learning has strong learning ability and generalization ability, and it is feasible and practical to apply the method to food image recognition.

Abstract
PURPOSE To investigate the impact of body mass index (BMI) on the aggressiveness of papillary thyroid cancer (PTC). METHODS A total of 1720 PTC patients with total thyroidectomy or lobectomy, from January 2017 to April 2020, were retrospectively evaluated. Based on BMI, they were divided into two groups, as follows: control (CON, < 24 kg/m2) and overweight and obesity (OB, ≥ 24 kg/m2), each sex being analyzed separately. RESULTS In the whole cohort, the OB group had significantly higher rates of extrathyroidal extension (21.5 vs. 16.8%, p = 0.013), multifocality (43.2 vs. 37.7%, p = 0.018), and BRAF-V600E mutation (82.9 vs. 79.3%, p = 0.015) than the CON group. In males, the OB group had increased rates of tumor size over 1cm (54.4 vs. 42.7%, p = 0.008), extrathyroidal extension (24.9 vs. 12.4%, p = 0.001), and multifocality (42.7 vs. 33.5%, p = 0.038). The OB group had significantly higher adjusted odds ratios (ORs) of 1.63 (1.14-2.33, p = 0.008), 2.12 (1.26-3.57, p = 0.005), and 1.56 (1.07-2.29, p = 0.022) for tumor size over 1cm, extrathyroidal extension, and multifocality compared with CON. Additionally, overweight and obesity were analyzed alone and the rates of extrathyroidal extension (30/100, 30.0%, p = 0.001) and tumor size over 1cm (65/100, 65.0%, p = 0.001) were significantly higher in the obesity group than in the overweight and CON groups. The obesity group had robust higher adjusted ORs of 2.51(1.50-4.20, p < 0.001), 2.93 (1.50-5.73, p = 0.002) and 1.89 (1.11-3.22, p = 0.020) for tumor size over 1cm, extrathyroidal extension, and multifocality compared with CON. CONCLUSIONS Overweight and obesity were predominant independent risk factors for PTC aggressiveness in males. These data indicated that the therapeutic treatment should be based on risk stratification by BMI in males.

Abstract
BACKGROUND AND AIMS The functions of liver fatty acid binding protein 1 (FABP1) in the regulation of nonalcoholic fatty liver disease (NAFLD) have been previously established. However, how FABP1 expression is dynamically regulated in metabolic disorders is unclear. Previous studies have reported that ubiquitin proteasome-mediated degradation of FABP1 is involved, but the mechanism remains unknown. METHODS Dysregulated expression of hepatic FABP1 and Derlin-1 was observed in NAFLD patients. We performed mice hepatic tissue coimmunoprecipitation based mass spectrum assays. Interaction between Derlin-1 and FABP1, and its impact on FABP1 ubiquitination status was evaluated by coimmunoprecipitation. The role of Derlin-1 in lipid deposition was tested using adenovirus-mediated overexpression in C57BL/6 mice, as well as by Derlin-1 overexpression or knockdown in HepG2 cells. RESULTS As a subunit of the endoplasmic reticulum-associated degradation complex, Derlin-1 was negatively associated with NAFLD patients, interacted with and ubiquitinated FABP1. Derlin-1 suppressed FABP1 levels and inhibited lipid deposition through a FABP1-dependent pathway. Additionally, Trim25, an E3 ubiquitin ligase present in the endoplasmic reticulum, was recruited to promote Derlin-1-related polyubiquitylation of FABP1, thereby creating a ubiquitin-associated network for FABP1 regulation. Derlin-1 overexpression ameliorated hepatic steatosis in both C57BL/6 mice and HepG2 cells, and contributed to attenuated weight gain, lower liver weight, and visceral fat mass. CONCLUSIONS FABP1 was degraded by Derlin-1 through ubiquitin modification. Negative regulation of FABP1 by Derlin-1 overexpression, suppressed lipid metabolism and alleviated lipid deposition in vivo and in vitro. Hence, Derlin-1 activation in hepatocytes may represent a potential therapeutic strategy for NAFLD.

Abstract
PURPOSE/OBJECTIVE(S) Deep inspiratory breath holding (DIBH) has been widely used during the radiotherapy of thoracic tumors. The main disadvantage of voluntary DIBH is the short duration of each breath hold. The hypocapnia induced by hyperoxia (oxygen concentration > 50%) pre-oxygenation (PreO2) combined with mechanical hyperventilation has been reported to prolong the duration of single breath hold, but its safety remains controversial, especially the sensitivity of lung tissue to radiation damage under hyperoxia exposure has not been elucidated. In this study, we aim to investigate the changes of radiation induced lung injury in rats after PreO2 radiation. MATERIALS/METHODS We evaluated the lung tissue of rats at different time points (48h, 2w, 4w, 8w, 12w) after thoracic radiation (15Gy single fraction to the right lung), and sequenced the transcriptome of lung tissue at 48 hours after irradiation. Rat cohorts (n = 7/group): 1. Control (Con); 2. Radiation group (RT); 3. Pre-oxygenation (oxygen concentration > 90%) for 8 hours before thoracic radiation (PreO2). RESULTS The inflammatory exudation emerged in the pulmonary interstitium at 48 hours, and reached the most serious alveolitis after four weeks of irradiation (the comparison of alveolitis scores in RT4w vs Con4w and PreO2(4w) vs Con4w, P<0.001) on hematoxylin-eosin staining. While the alveolitis scores in RT group and PreO2 group were not statistically different at each time point. Masson staining showed that the pulmonary fibrosis in the RT group and the PreO2 group reached an obvious pathological change at 12 weeks after irradiation, but the difference between the two groups was not significant. Transcriptome sequencing showed that the number of differential genes in PreO2 vs Con was 559 (302 up-regulated genes and 257 down-regulated genes). The GO enrichment analysis indicated that chromosome segregation was the most significant functional item with P value in the comparative analysis, and the KEGG enrichment analysis suggested that cell division was the most significant enrichment pathway of these differential genes. While there was a small quantity of differential genes in PreO2 vs RT group (3 up-regulated genes and 12 down-regulated genes). Pentose and glucuronate conversions were the most significant enrichment pathway of these differential genes. CONCLUSION This study demonstrated that PreO2 radiotherapy did not increase the severity of radiation induced lung injury in rats compared to conventional radiotherapy. Further study should be conducted to confirm these results and to investigate the regulatory mechanism of pneumonia caused by PreO2 radiotherapy.

Abstract
The aim of this study was to compare single- and double-layer digital template-assisted genioplasty for the correction of jaw deformity resulting from temporomandibular joint ankylosis (TMJA). Thirteen patients with jaw deformity resulting from TMJA who underwent lateral arthroplasty, costochondral graft, or total joint replacement combined with single- or double-layer digital template-assisted genioplasty were included. Computed tomography data were obtained for the preoperative design. Digital templates were designed and manufactured using three-dimensional printing to assist with the chin osteotomy and repositioning in single- or double-layer genioplasty. Of the 13 patients included, seven underwent single-layer genioplasty and six underwent double-layer genioplasty. The digital templates precisely reflected the osteotomy planes and repositioning of the chin segments intraoperatively. The radiographic evaluation showed that the patients who underwent double-layer genioplasty exhibited more chin advancement (11.95 ± 0.92 mm vs 7.50 ± 0.89 mm; P < 0.001) with a slightly larger mean surface error (1.19 ± 0.14 mm vs 0.75 ± 0.15 mm; P < 0.001) than those who underwent single-layer genioplasty. This indicates that double-layer genioplasty better promoted chin advancement and improved the facial shape, but was accompanied by more surgical error compared with the preoperative design. Furthermore, hardly any nerve damage was observed. Digital templates are useful for assisting in surgical procedures.

Abstract
Objective To explore the predictors of menstrual recovery in polycystic ovary syndrome (PCOS) women with obesity following laparoscopic sleeve gastrectomy (LSG). Methods A total of 88 PCOS patients with obesity and 76 control patients with obesity aged 18-45 years were enrolled between May 2013 and December 2020. PCOS was diagnosed using the Rotterdam diagnostic criteria (2003). Anthropometric measurements, biochemical parameters, sex hormones, and circulating fibrinogen-like protein 1 (FGL-1) levels were collected before and six-month after LSG. The data on postoperative menstrual status, body weight, and fertility were obtained through telephone follow-ups for all individuals with PCOS. Results Patients with PCOS were followed up for at least six months after surgery, and the mean follow-up time was 3.23 years. At 6 months after LSG, circulating total testosterone (TT), calculated free testosterone (cFT), and FGL-1 levels declined significantly. The mean percent excess weight loss (%EWL) and percent total weight loss (%TWL) in PCOS patients at the final follow-up was 97.52% ± 33.90% and 31.65% ± 10.31%, respectively. The proportion of regular menstruation in PCOS patients significantly increased within six months (75.86% vs 0.03% at baseline). In the logistic regression analysis, time from PCOS diagnosis (P=0.007), body mass index (BMI) (P=0.007), TT (P=0.038) at baseline were demonstrated to be independent predictive factors for the regular menstruation in women with PCOS and obesity within 6 months after LSG. Conclusion In PCOS patients with obesity, time from PCOS diagnosis, BMI, and TT levels at baseline were independently and negatively associated with menstrual recovery within 6 months after LSG, which could be applied in preoperative evaluation.

Abstract
To investigate the cross-sectional and longitudinal correlation between serum superoxide dismutase (SOD) levels and thyroid function with obesity before and after laparoscopic sleeve gastrectomy (LSG). Patients with morbid obesity (n = 219, 112 males and 107 females) who underwent LSG were selected and they were subdivided into normal levels of SOD (NSOD, n = 112) and high levels of SOD (HSOD, n = 107) according to the median value of SOD levels (183 U/mL). SOD and thyroid hormones were measured and compared at baseline, 3, 6, and 12 months after LSG. The HSOD group had lower body mass index (BMI), total thyroxine (TT4), and thyroid-stimulating hormone (TSH) than the NSOD group (p < 0.001, p = 0.031, p < 0.001, respectively). However, they had higher free triiodothyronine (FT3) and free thyroxine (FT4) (p = 0.019 and p = 0.017, respectively). SOD was significantly negatively associated with TSH and positively associated with FT4. Of all the patients, 22.31% (NSOD: 66.67%; HSOD: 33.33%) had subclinical hypothyroidism (SH), and there were lower SOD levels in the SH group. Preoperative SOD was a protective factor for SH. After LSG, SOD and FT4 levels were increased at 12 months after LSG, however, TSH, FT3, total triiodothyronine (TT3) and TT4 levels decreased compared to the preoperative levels at 3, 6, and 12 months in the SH group. Postoperative changes in FT4 and TT4 levels correlated with changes in SOD levels. SOD, which is correlated with thyroid hormones, protects against SH in patients with obesity. The improvement in thyroid function with SH after LSG may be related to increased SOD levels.

Abstract
Objective: To investigate the clinical characteristics and pregnancy outcomes in pregnant women with left ventricular non-compaction (LVNC). Methods: The clinical data of seven pregnant women with LVNC from January 2011 to December 2021 in Beijing Anzhen Hospital,Capital Medical University were retrospectively analyzed, including age, gestational age of symptom first occured, LVNC history, clinical symptoms, New York Heart Association (NYHA) cardiac function class, echocardiography, blood brain natriuretic peptide (BNP), treatment and the maternal and fetal outcomes. Results: Five cases were diagnosed before pregnancy, of which there were three women with medication; one case diagnosed in the month of pregnancy; one case diagnosed at 36 weeks of gestation. NYHA cardiac function was grade Ⅰ in four cases and grade Ⅱ in three cases before or during the first trimester of pregnancy. Of the five pregnant women who underwent echocardiography, there were one case of left ventricular insufficiency, three cases of mild left ventricular dysfunction and one case of normal left ventricular function before or during the first trimester of pregnancy. Of the five pregnant women to the second and third trimester of pregnancy, there were one case of grade Ⅳ, one case of grade Ⅲ, two cases of grade Ⅱ-Ⅲ and one case of grade Ⅱ in NYHA class ; three cases of left ventricular insufficiency, two cases of normal left ventricular function by echocardiography four cases had cardiac symptoms at 15-24 weeks of gestation and were treated with medication. In four cases, blood BNP increased to 214-1 197 ng/L during pregnancy, and were 89-106 ng/L after termination of pregnancy. There were 4 cases with arrhythmia. Indications for termination of pregnancy: LVNC complicated with heart failure in two cases, LVNC complicated with decreased cardiac function and threatened preterm birth in one case, complicated with pregnancy at full term in two cases, LVNC complicated with severe pulmonary hypertension in one case, and left ventricular dysfunction in one case. Cesarean section in four cases in the third-trimester, in one case in the second-trimester, and forceps curettage in two cases were taken. Two full-term infants,two preterm infants were born without LVNC. Conclusions: Women diagnosed with LVNC and low left ventricular ejection fraction before pregnancy are more prone to decreased cardiac function during pregnancy. Carrying out pregnancy risk assessment and strengthening the multi-disciplinary team management of high risk factors in pregnancy are conducive to achieve good pregnancy outcomes.

Abstract
Background Bariatric surgery is the most effective therapy for obesity, but targeted weight reduction is not always achieved. Serum lipocalin-2 (LCN2) is closely associated with obesity, but its impact on weight loss after surgery is unknown. We aimed to access the reliability of LCN2 levels and other parameters as effective predictors of excellent weight loss (≥ 75% excess weight loss (EWL)) 1 year after bariatric surgery. Methods This retrospective study evaluated 450 patients (aged 18–65 years) with obesity at 3 months and 1 year after laparoscopic sleeve gastrectomy (LSG) surgery. Seventy-four patients who underwent LSG surgery and met the inclusion and exclusion criteria were included in this study. Serum LCN2, thyroid function, and metabolic and anthropometric parameters were assessed. Weight reduction was expressed as %EWL and percent total weight loss (%TWL) at 3 months and 1 year post surgery. Multivariable logistic regression analysis and receiver operating characteristic (ROC) curve analysis were used to evaluate predictors of ≥ 75%EWL. Results In our cohort, %EWL and %TWL were both strongly associated with preoperative serum LCN2 levels. The binary logistic regression analysis showed that preoperative LCN2, waist circumference, and glycated hemoglobin were independent predictors of excellent weight loss. Conclusions Based on these results, we determined a new P index with better predictive value for excellent weight reduction (≥ 75%EWL) 1 year after LSG surgery. Graphical abstract ![]()

Abstract
BACKGROUND Lipocalin-2 (LCN2) has a critical effect on obesity as well as its associated comorbidities. The present study focused on analyzing serum LCN2 levels of obese patients with nonalcoholic fatty liver disease (NAFLD) and on determining relationship of hepatic steatosis improvement with LCN2 levels after laparoscopic sleeve gastrectomy (LSG). METHODS This work enrolled ninety patients with obesity and NAFLD. Twenty-three of them underwent LSG. Anthropometric and biochemical parameters and serum LCN2 levels were determined at baseline and those at 6-month post-LSG. Controlled attenuation parameter (CAP) measured by FibroScan was adopted for evaluating hepatic steatosis. RESULTS Among severe obesity patients, serum LCN2 levels were significantly increased (111.59 ± 51.16 ng/mL vs. 92.68 ± 32.68 ng/mL, P = 0.035). The CAP value was higher indicating higher liver fat content (360.51 ± 45.14 dB/m vs. 340.78 ± 45.02 dB/m, P = 0.044). With regard to surgical patients, liver function, glucose, and lipid levels were significantly improved after surgery. Serum LCN2 levels significantly decreased (119.74 ± 36.15 ng/mL vs. 87.38 ± 51.65 ng/mL, P = 0.001). Decreased CAP indicated a significant decrease in liver fat content (358.48 ± 46.13 dB/m vs. 260.83 ± 69.64 dB/m, P < 0.001). The decrease in LCN2 levels was significantly related to the reduced hepatic fat content and improvement in steatosis grade after adjusting for gender, age, and BMI decrease. CONCLUSIONS Serum LCN2 levels are related to obesity and NAFLD. The decreased serum LCN2 levels could be an indicator of hepatic steatosis improvement.

Abstract
BACKGROUND Liver-type fatty acid-binding protein (FABP1) contributes to metabolic disorders. However, the relationship between FABP1 and hyperuricemia remains unknown. We aimed to evaluate the correlation between serum FABP1 and hyperuricemia in patients with obesity before and after laparoscopic sleeve gastrectomy (LSG). METHODS We enrolled 105 patients (47 men and 58 women) with obesity who underwent LSG. They were divided into two groups: normal levels of uric acid (UA) (NUA, n = 44) and high levels of UA (HUA, n = 61) with matching sexes. FABP1 levels and other biochemical parameters were measured at baseline and 3, 6, and 12 months after LSG. RESULTS Serum FABP1 levels were significantly higher in the HUA group than in the NUA group (34.76 ± 22.69 ng/mL vs. 25.21 ± 21.68 ng/mL, P=0.024). FABP1 was positively correlated with UA (r=0.390, P=0.002) in the HUA group. The correlation still existed after adjusting for confounding factors. Preoperative FABP1 levels were risk factors for hyperuricemia at baseline. UA and FABP1 levels decreased at 3, 6, and 12 months postoperatively. FABP1 showed a more significant decrease in the HUA group than in the NUA group at 12 months (27.06 ± 10.98 ng/mL vs. 9.54 ± 6.52 ng/mL, P=0.003). Additionally, the change in FABP1 levels positively correlated with changes in UA levels in the HUA group 12 months postoperatively (r=0.512, P=0.011). CONCLUSIONS FABP1 was positively associated with UA and may be a risk factor for hyperuricemia in obesity. FABP1 levels were higher but decreased more after LSG in obese patients with hyperuricemia than in those without hyperuricemia.

Abstract
BACKGROUND Metabolic dysfunction associated fatty liver disease (MAFLD) is the most common hepatopathy worldwide due to the obesity epidemic and is associated with chronic low-grade inflammation. High-sensitive C-reactive protein (hsCRP) as an inflammatory marker has been used in diagnosing MAFLD. However, the association between hsCRP and the severity of liver steatosis and fibrosis among obese patients with MAFLD remains to be elucidated. OBJECTIVE To explore the correlation of hsCRP with the severity of liver steatosis and fibrosis among Chinese obese patients with MAFLD. METHODS A total of 393 obese patients with mean BMI 34.8 ± 6.6 kg/m2 were selected and categorized as MAFLD and non-MAFLD groups. Anthropometric data, biochemical indices, and hsCRP were measured. The severity of hepatic steatosis and fibrosis was assessed using FibroScan. Multivariate logistic regression analysis was performed to determine the relationship between hsCRP and the risk of MAFLD and its disease severity. RESULTS Patients with MAFLD showed significantly elevated hsCRP levels and were more likely to have severe steatosis and fibrosis compared to those without MAFLD. The proportions of MAFLD, severe steatosis, and severe fibrosis were significantly increased across the hsCRP quartiles (P-trend = 0.004, 0.021, and 0.006, respectively). After multivariable adjustments, the adjusted ORs (AORs) and 95%CI for MAFLD were 1.00 (reference), 1.298 (0.587-2.872), 2.407 (1.002-5.781), and 2.637(1.073-6.482) (Q1-Q4, P-trend = 0.014). Likewise, the AORs (95%CI) for severe steatosis and severe fibrosis were remarkably increased with the increment of serum hsCRP quartiles (P-trend < 0.001, P-trend = 0.021, respectively). CONCLUSIONS Elevated serum hsCRP levels were associated with increased risk of MAFLD among Chinese obese patients and correlated positively with the severity of liver steatosis and fibrosis, suggesting that hsCRP can be used as a potential biomarker to monitor and predict disease severity among Chinese obese population with MAFLD.

Abstract
BACKGROUND Metabolic-associated fatty liver disease (MAFLD) has become a worldwide epidemic. Prolactin (PRL), a pituitary hormone, has been linked to MAFLD. As a result, we set out to look into the relationship between serum PRL and the risk of MAFLD in patients with type 2 diabetes mellitus (T2DM). METHODS A total of 724 adults with T2DM were enrolled and categorized as MAFLD and non-MAFLD groups. Anthropometric data, biochemical parameters, and serum PRL levels were collected. Liver steatosis and fibrosis were assessed using FibroScan. Patients were stratified into normal PRL (NP) and high PRL (HP) groups and divided into four groups based on serum PRL quartiles. Multivariate logistic regression analysis was performed to evaluate the association between serum PRL and MAFLD risk. RESULTS Female but not male patients with MAFLD, liver steatosis, and fibrosis had significantly lower PRL levels in the NP group but higher PRL levels in the HP group than their counterparts. The proportions of MAFLD, liver steatosis, and fibrosis were significantly decreased in the NP group but increased in the HP group across the PRL quartiles in females but not in males. After multivariate adjustment, the adjusted ORs (AORs) and 95% CI for MAFLD among females were 18.165 (3.425-96.336), 1.784 (0.658-5.002), 1.744 (0.608-4.832), and 1.00 (reference) in the NP group (Q1-Q4, P-trend < 0.001) and 1.00 (reference), 11.098 (1.819-110.356), 15.225 (1.996-116.112), and 18.211 (2.579-128.568) in the HP group (Q1-Q4, P-trend = 0.020). Such associations were also found between serum PRL and liver fibrosis in females but not in males. CONCLUSION We observed a J-shaped association between serum PRL and the risk of MAFLD and liver fibrosis in females but not in males with T2DM, indicating that PRL may be relevant to MAFLD and its progression in a gender-specific manner.

Abstract
We describe the use of on-chip buckled-dome Fabry-Perot microcavities as pressure sensing elements. These cavities, fabricated by a controlled thin-film buckling process, are inherently sealed and support stable optical modes (finesse >103), which are well-suited to coupling by single-mode fibers. Changes in external pressure deflect the buckled upper mirror, leading to changes in resonance wavelengths. Experimental shifts are shown to be in good agreement with theoretical predictions. Sensitivities as large as ∼1nm/kPa, attributable to the low thickness (<2µm) of the buckled mirror, and resolution ∼10Pa are demonstrated. We discuss potential advantages over traditional low-finesse, quasi-planar Fabry-Perot pressure sensors.

Abstract
Gastric mucosal injury is a less well known complication of obesity. Its mechanism remains to be further elucidated. Here, we explored the protective role of lipocalin 2 (LCN2) against endoplasmic reticulum stress and cell apoptosis in gastric mucosa in patients and mice with obesity. Through molecular and genetic analyses in clinical species, LCN2 secreted by parietal cells expression is elevated in obese. Immunofluorescence, TUNEL, and colorimetry results show that a more significant upregulation of pro-inflammatory factors and increased amount of apoptotic cells in gastric tissue sections in obese groups. Loss- and gain-of-function experiments in gastric epithelial cells demonstrate that increased LCN2 protected against obesity associated gastric injury by inhibiting apoptosis and improving inflammatory state. In addition, this protective effect was mediated by repressing ER stress. Our findings identify LCN2 as a gastric hormone could be a compensatory protective factor against gastric injury in obese.

Abstract
Purpose: To investigate the risk-stratifying utility of tumor size and a threshold for further stratification on cancer-specific mortality of thyroid cancer (TC) patients in stage IVB. Methods: One thousand three hundred and forty-five patients (620 males and 725 females) with initial distant metastasis over 55 years between 2004 and 2016 from Surveillance, Epidemiology, and End Results databases were investigated, with a median follow-up time of 23 months [interquartile range (IQR), 5–56 months] and a median age of 70 years (IQR, 63–77 years). TC-specific mortality rates were calculated under different classifications. Cox regressions were used to calculate hazard ratios (HRs) and Kaplan-Meier Analyses were conducted to investigate TC-specific survivals. Results: In the whole cohort, patients with tumors >4 cm had the highest TC-specific mortality (67.9%, 330/486), followed by tumor size >1 cm but ≤ 4 cm (43.08%, 190/441), and tumor size ≤ 1 cm (32.69%, 34/104). Kaplan-Meier curves showed the increased tumor size was associated with a statistically significant decrease in TC-specific survival (P < 0.001). Papillary thyroid cancer (PTC) patients with tumors >4 cm had significantly higher hazard ratios (HRs) of 2.84 (1.72–4.70) and 3.11 (1.84–5.26) after adjusting age, gender, race, and radiation treatment, compared with patients with tumors ≤ 1 cm (P < 0.001). The TC-specific mortalities and survivals were further investigated among more detailed subgroups divided by different tumor size, and a threshold of 3 cm could be observed (P < 0.005) for risk stratification. Conclusions: Mortality risk increased with tumor size in PTC patients in stage IVB. Our findings demonstrated the possibility of further stratification in IVB stage in current TNM staging system. Patients with tumor size over 3 cm had an excessively high risk of PTC-specific mortality, which may justify the necessity of more aggressive treatment for them.

Abstract
Islet beta-cell dysfunction is an important condition leading to the development of diabetes. Numerous studies have found that miRNA regulates islet β-cell function. In our previous research, the aberrant expression of miR-383 was revealed in type 2 diabetes mellitus (T2DM) serum. Herein, we aimed to assess the function and underlying mechanism of miR-383 in β-cells through in vitro and in vivo experiments. Using high glucose media, the β-cell injury was induced and transfected miR-383 overexpression vector to detect cell function in MIN6. Moreover, miR-383 overexpression lentivirus was administrated into high-fat induced diabetes mice to assess the in vivo effect. Results showed that overexpressing miR-383 reversed the cell apoptosis and oxidative stress, induced by high glucose which targets Toll-like receptors (TLR4) and Apolipoprotein C3 (ApoC3) genes. Furthermore, mechanistic studies demonstrated that miR-383 targeted the TLR4 and ApoC3 3' UTR consequently inhibiting TLR4 and ApoC3 expression in MIN6 cells. Besides, overexpression of miR-383 ameliorated hyperglycemia and pancreatic apoptosis in high-fat induced diabetic mice. Conclusively, miR-383 potentially alleviate pancreatic β-cell injury induced by high glucose and ameliorates high-fat induced diabetes by suppressing TLR4 and ApoC3 expression.

Abstract
AIMS Coronavirus disease 2019 (COVID-19) has become a recognized worldwide pandemic. Researchers now know that mortality from COVID-19 can be reduced through early prevention measures. This retrospective, multi-centered study of 293 COVID-19 patients without diabetes explores the association between fasting blood glucose (FBG) levels and the risk of COVID-19 disease progression, with the goal of providing clinical evidence for glycemic targets in patients. METHODS The multivariate stepwise binary logistic regression analysis was used to test the dose-response effects of FBG levels on the risk of severe and critical condition in COVID-19 patients. RESULTS FBG levels were plotted in quintiles with set at <4.74, 4.74-5.21, 5.21-5.78, 5.78-7.05, and ≧7.05 mmol/L. The constituent ratio of severe or critical cases in each FBG quintile was 20.7%, 1.7%, 13.8%, 27.1%, and 67.2%, respectively (P < 0.0001). When the second quintile was used as the reference, the adjusted odds ratios (AORs) (95%CI) for the risk of severe/critical condition in COVID-19 was 25.33 (2.77, 231.64), 1.00 (Reference), 3.13 (0.33, 29.67), 10.59 (1.23, 91.24), 38.93 (4.36, 347.48) per FBG quintile respectively (P < 0.001). CONCLUSIONS We provide evidence of J-shaped associations between FBG and risk of severe and critical condition in non-diabetes patients with COVID-19, with nadir at 4.74-5.78 mmol/L.

Abstract
We describe curved-mirror Fabry-Perot cavities with embedded silicon nitride membranes, fabricated using a monolithic surface-micromachining process. The presence of the suspended membranes was confirmed by confocal microscopy, and their properties were verified through optical studies and thermomechanical calibration of mechanical/vibrational noise spectra measured at room temperature and atmospheric pressure. The cavities exhibit reflectance-limited finesse (F ∼ 103) and wavelength-scale mode volumes (VM ∼ 10·λ3). The short cavity length (L ∼ 2·λ) results in large optomechanical coupling, which is desirable for numerous applications in sensing and quantum information.

Abstract
BACKGROUND Although the results of our and other studies show that baicalin can enhance glucose uptake and insulin sensitivity in skeletal muscle and adipocytes of mice, the specific metabolic contribution of baicalin on hepatic insulin resistance and gluconeogenic activity is still unclear. PURPOSE The aim of this study is to investigate whether baicalin is involved in regulation of hepatic insulin resistance and gluconeogenic activity and its underlying mechanisms. STUDY DESIGN/METHODS In the present study, high-fat diet-induced obese mice were given 50 mg/kg baicalin intraperitoneally (i.p.) once a day for 21 consecutive days, and hepatocytes were treated with baicalin (100 μM) or metformin (100 μM) in the presence of glucagon (200 nM) for 12 h. Then insulin resistance indexes and genes related to gluconeogenesis were examined in liver tissues. RESULTS The present findings showed that baicalin decreased body weight, HOMA-IR, and alleviated high fat diet-induced glucose intolerance, hyperglycemia and insulin resistance in diet-induced obese mice. Furthermore, baicalin markedly suppressed p-p38 MAPK, p-CREB, FoxO1, PGC-1α, PEPCK and G6Pase expression in liver of obese mice and hepatocytes. Moreover, inhibition of gluconeogenic genes by baicalin was also strengthened by p38MAPK inhibitor in hepatocytes. CONCLUSION Baicalin suppressed expression of PGC-1α and gluconeogenic genes, and reduced glucose production in high-fat diet-induced obese mice. Baicalin ameliorated hepatic insulin resistance and gluconeogenic activity mainly through inhibition of p38 MAPK/PGC-1α signal pathway. This study provides a possibility of using baicalin to treat hyperglycemia and hepatic insulin resistance in clinic.

Abstract
We describe a tunable bandpass filter and polarizer based on resonant tunneling through an air gap between two hemi-cylindrical prisms coated with 4-layer a-Si/SiO2 matching stacks. Tuning is achieved by simultaneous variations in the incident angle and the air gap thickness, enabling the pass-band center wavelength to be continuously adjusted over a very wide range (potentially ~1000 - 1800 nm) with an approximately fixed fractional bandwidth (Δλ/λ ~1%). An analytical derivation of the conditions required to produce a flat-top TE pass-band at a desired wavelength is given. The filter provides excellent out-of-band rejection and strong suppression of the orthogonal TM polarization over the entire tuning range. For applications involving collimated light, it could be a useful alternative to existing widely tunable filters based on gratings or liquid crystals.

Abstract
OBJECTIVE Lipocalin-2 (LCN2) plays an important role in the regulation of the obesity and obesity-related dysmetabolic state. This study aimed to analyze serum LCN2 level in Chinese women with obesity before and after laparoscopic sleeve gastrectomy (LSG) and determine the association between alteration in fat mass and bone mineral density (BMD) and LCN2 level. METHODS Fifty-two women (38 patients with obesity and 14 with normal body mass index (BMI)) were enrolled in this study. All patients with obesity underwent LSG. BMDs of the arm, leg, thoracic and lumbar spine, and pelvis were measured by dual-energy X-ray absorptiometry. Body fat mass and distribution were measured by dual-energy X-ray absorptiometry, and routine anthropometric/laboratory biochemical parameters at baseline and 3 and 12 months after LSG were recorded. Serum LCN2 levels were measured using an enzyme-linked immunosorbent assay. RESULTS Serum LCN2 level was significantly higher in women with obesity than in the controls with normal BMI (102.70 ± 27.19 vs. 80.66 ± 19.55 ng/mL, P = 0.009). LCN2 level was decreased at 3 and 12 months after LSG (86.73 ± 26.79 ng/mL, P = 0.171, and 64.79 ± 28.39 ng/mL, P < 0.001, respectively). LSG led to marked body fat mass and slight BMD decrease. Decreased LCN2 level was significantly correlated with alterations in left and right leg BMDs and trunk fat mass at 12 months after LSG. CONCLUSIONS Obesity was associated with up-regulated serum LCN2 level. Decreased LCN2 level was positively correlated with changes in BMD and fat mass at 12 months after LSG in Chinese women.

Abstract
BACKGROUND Hyperuricemia is related to obesity and fat accumulation. This study aimed to observe the effects of laparoscopic sleeve gastrectomy (LSG) on serum uric acid (sUA) level and body fat distribution in obese patients. The relationships between post-LSG improvement in sUA levels and body fat distribution changes, as well as their sex-related differences, were also explored. METHODS In total, 128 obese patients (48 men; 80 women) who underwent LSG were enrolled. Anthropometric indicators, glucose and lipid metabolic indicators, and sUA levels were measured pre-LSG and 6 months post-LSG. The body compositions were measured via dual-energy X-ray absorptiometry. The patients were divided into normal-sUA (NUA) and high-sUA (HUA) groups based on preoperative sUA levels. RESULTS Compared with the NUA group, the reduction of sUA levels 6 months post-LSG was more significant in the HUA group. In addition, sUA reduction in the female HUA group was more significant than that of the male HUA group (P < 0.01). Changes in serum uric acid levels (ΔsUA) in the male HUA group was positively correlated with changes in body weight, body mass index, neck circumference, and hip circumference (r = 0.618, 0.653, 0.716, and 0.501, respectively; P < 0.05 in all cases). It was also positively correlated with changes in fat mass in the gynoid region, android region, and legs, (r = 0.675, 0.551, and 0.712, respectively; P < 0.05 in all cases), and negatively correlated with changes in total testosterone (ΔTT) (r = - 0.517; P = 0.040). Furthermore, ΔTT in this group was closely associated with the improved sex-related fat distribution. The ΔsUA in the female HUA group was positively correlated with changes in fasting serum C peptide and ΔLNIR (r = 0.449 and 0.449, respectively; P < 0.05 in both cases). In addition, it was also positively correlated with changes in visceral adipose tissue (VAT) fat mass, VAT fat volume, and VAT fat area (r = 0.749, 0.749, and 0.747, respectively; P < 0.01 in all cases). CONCLUSIONS sUA levels of obese patients with hyperuricemia improved 6 months after LSG. Reduction of sUA after LSG was correlated with improved body fat distribution, and the relationships also displayed sex-based differences. Uric acid might be an important metabolic regulator associated with fat distribution and sex hormones.

Abstract
BACKGROUND AND OBJECTIVE The stomach plays an important role in obesity and obesity-related diabetes; yet, little is known about key pathways in the gastric mucosa associated with obesity and diabetes. METHODS We performed gene microarray and real time-polymerase chain reaction (RT-PCR) on gut mucosa samples from control subjects (CON), patients with simple obesity (OB), and patients with obesity and comorbid diabetes (OD) (n = 3 per group). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were used to predict the functional significance of differentially expressed genes. RESULTS In total, 262 genes were upregulated and 265 genes were downregulated in the OB group whereas 1756 genes were upregulated and 1053 genes were downregulated in the OD group compared with the CON group. Of these, 23 were co-regulated in both comparisons. Seven differentially expressed genes were validated by RT-PCR (NRIP3, L1CAM, TPO, P2RY1, OR8A1, ADAMTS19, and ASIC3). A functional analysis revealed that genes differentially expressed between the OB or OD and CON groups played crucial roles in metabolic, T cell, and G-protein coupled receptor biological processes, and primarily participated in the PI3K-Akt and AGE-RAGE signaling pathways. CONCLUSIONS Obesity and obesity-related diabetes are associated with important gene expression and pathway alterations in the stomach.

Abstract
OBJECTIVE To assess the effects of laparoscopic sleeve gastrectomy (LSG) on insulin secretion mode and metabolism of glucose and lipid in morbidly obese patients. METHODS Clinical data of 65 morbidly obese patients [body mass index (BMI) ≥30 kg/m2] undergoing LSG at Shanghai 10th People's Hospital from August 2012 to December 2016 were retrospectively analyzed. According to the result of OGTT, these obese patients were divided into three groups: normal glucose tolerance (NGT, 23 cases), impaired glucose tolerance (IGT, 22 cases) and type 2 diabetes mellitus (DM, 20 cases) groups. Twenty-two healthy people [BMI (23.1±1.4) kg/m2] were used as control group. The anthropometries parameters [weight, BMI, waist circumference, body fat percentage, excess weight loss(%EWL)], glucose metabolic indices [fasting plasma glucose (FPG), fasting insulin (FINS), glycosylated hemoglobin (HbA1c), homeostasis model assessment-insulin resistance index (HOMA-IR)], lipid profile (TC, TG, HDL-C, LDL-C) and inflammatory factor (UA, TNF-α) of 3 groups were detected before operation and at postoperative 1-, 3-, 6-month. These variables were analyzed among morbidly obese groups before and after surgery and compared to control group. Clinical registration number of this study was ChiCTROCSl2002381. RESULTS Body weight, waist circumference and BMI of morbidly obese patients all decreased at postoperative 1-, 3-, 6-month. Postoperative %EWL increased obviously to (71.5±24.7)% with the highest range in DM group. Percentage of successful weight loss (%EWL>50%) in NGT, IGT and DM groups was 63.6%, 83.9% and 90.0% at postoperative 6-month respectively, and DM group was also the highest. At postoperative 6-month, HbA1c of 3 morbidly obese groups became normal; FPG and postprandial 2-hour glucose of IGT and DM group decreased to normal level; insulin level of 3 morbidly obese groups decreased obviously compared to pre-operation (all P<0.05), especially FINS and postprandial 2-hour insulin became normal without significant difference of control group (P>0.05), while postprandial 30-minute and 60-minute insulin levels in 3 groups were still higher as compared to control group. The insulin secretion curves of morbidly obese groups showed hyperinsulinemia before surgery. The peak of insulin secretion curve in IGT and DM group moved back to postprandial 120-minute before operation, and returned to 60-minute after operation, with basic normal rhythm of secretion curve. Preoperative HOMA-IR in all 3 morbidly obese groups was higher than that in control group (all P<0.05) and remarkably lower at postoperative 6-month compared to pre-operation(P<0.05). In 3 morbidly obese groups after operation, TG decreased, HDL-C increased, UA and TNF-α decreased significantly compared to before operation (all P<0.05). At postoperative 6-month, the HOMA-IR of DM group was positively correlated with BMI (r=0.236, P=0.004) and TNF-α (r=0.228, P=0.033), and was not correlated with HDL-C(P>0.05). CONCLUSIONS LSG can effectively ameliorate hyperinsulinemia and insulin secretion curve, and improve metabolic disorder and insulin resistance of different stage in obesity patients with glucose metabolic disorder. Insulin resistance is correlated with body weight and inflammatory factors.

Abstract
Aims: Whether pioglitazone (PIO), a peroxisome proliferator-activated receptor-gamma agonist, increases the risk of developing bladder cancer has been debated for several years. The aim of this study was to investigate the in vitro effects of PIO on normal urothelial transitional epithelium (NUTE) cells and bladder cancer (J82) cells to further evaluate the risk. Methods: NUTE cells were obtained from Sprague-Dawley rats. NUTE and J82 cells were treated with different concentrations of PIO for various time periods. Cell proliferation was tested by the MTT assay. Cell apoptosis was evaluated by flow cytometry. The expressions of p53, cyclin D1, Bcl-2, and Bax were determined by qRT-PCR and western blots. Results: After 24 hours, the treatment of NUTE cells with 10 μmol/L PIO led to morphological changes, without changes in J82 cells. Moreover, PIO inhibited the proliferation and induced apoptosis of NUTE cells, but not J82 cells, in a time- and dose-dependent manner. However, PIO did not alter the growth of cells from other tissues. In addition, treatment with PIO for up to 72 hours did not result in changes in the expressions of p53, cyclin D1, Bcl-2, and Bax in NUTE cells and J82 cells. Interestingly, PIO significantly downregulated the protein levels of p53 and cyclin D1 in J82 cells, but not NUTE cells after more than 192 hours of treatment. Conclusions: PIO did not promote malignant alterations of NUTE cells or stimulate proliferation of J82 cells. PIO decreased the expression of p53 and cyclin D1 in J82 cells after long-term culture, which suggested that PIO may be helpful for diabetic patients with bladder cancer.

Abstract
BACKGROUND Acanthosis nigricans (AN) has a close relationship with obesity. It is believed that obesity and AN have the common pathophysiological basis such as hyperinsulinism. This study is aimed to observe the effect of laparoscopic sleeve gastrectomy (LSG) on body composition and insulin resistance in Chinese obese patients with acanthosis nigricans. METHODS A total of 37 obese patients who underwent LSG in our hospital were selected for analysis. They were divided into simple obesity (OB n = 14) and obesity with acanthosis nigricans (AN n = 23) group respectively. Body composition was measured by dual-energy X-ray absorptiometry (DEXA). Anthropometric measurements and glucolipid metabolism before and 3 months post LSG were collected for analysis. RESULTS Patients with AN got noticeable improvement in skin condition and their AN score was significantly decreased (3.52 ± 0.79 vs. 1.48 ± 0.73, P < 0.001).Alleviated insulin resistance and more trunk fat loss than limbs' were observed in both groups (P value < 0.01). In AN group, preoperative android fat mass (FM) was positively correlated with fasting insulin and natural logarithm of HOMA-IR (LNIR) (r = 0.622, 0.608, respectively; all P < 0.01). Besides, changes in android FM and visceral adipose tissue (VAT) also showed significantly positive correlation with changes in LNIR (r = 0.588, r = 0.598, respectively; all P < 0.01). CONCLUSIONS LSG had a positive impact on body composition and skin condition in Chinese obese patients with AN. Loss of android FM and VAT might result in the alleviation of insulin resistance in AN patients. Android fat distribution seems to be a potential indicator of postoperative metabolic benefits for obese patients with AN.

Abstract
BACKGROUND We used the leptin-receptor (LPR)-deficient mice model (db/db), a spontaneous model of type 2 diabetes with early β cell dysfunction to determine whether a preventative sleeve gastrectomy (SG) is an effective technique for the treatment of β cell failure. METHODS The animals operated at an early stage of life, prior to metabolic alterations, were used to study the molecular mechanisms of β cell function improvement after a SG. RESULTS β cell function was significantly increased, and islet morphology remained normal, after the SG. The expression of Glut2, Pdx1, MafA, and Nkx6.1 were significantly increased after the SG. The expression of GLP-1 in the colonic tissue, as well as GLP-1R and PKC in islets, was significantly increased after the SG. CONCLUSIONS β cell dysfunction can be ameliorated by a preventative SG for db/db mice. Maintaining the GLP-1 pathway and key transcript factor (TF) activation contributes to the improvement of β cell function after a preventative SG.

Abstract
Background Bone morphogenetic protein 4 (BMP-4) has been proven to regulate white adipogensis. We aimed to demonstrate the correlation of BMP-4 with fat distribution and Exenatide treatment on it. Methods We enrolled 69 obese patients. Anthropometric and metabolic indexes were collected. Fat distribution was measured by dual-energy X-ray absorptiometry. BPM-4 levels were assessed using enzyme-link immunosorbent assay kit. 30 obese patients were treated with Exenatide twice a day. Change in body weight, metabolic-related indices and BPM-4 levels were evaluated after 18 weeks. Results 1) The mean(±SD) BMP-4 levels were 763.98 ± 324.11 pg/ml in the obese. BPM-4 levels were significantly positively correlated with estimated visceral adipose tissue mass in all subjects and also in females (r = 0.377, r = 0.625, respectively,all P < 0.05). BPM-4 levels were also significantly positively correlated with body mass index, hip circumference and total fat% in females (r = 0.375,r = 0.429,r = 0.493,respectively, all P < 0.05). BPM-4 levels were negatively correlated with total cholesterol(TC) in all subjects and males also (r = −0.373,r = −0.332,respectively, all P < 0.05). BPM-4 levels were also significantly positively correlated with free triiodothyronine in males (r = 0.441, P < 0.05). 3) Multivariate analyses showed that TC was risk factor of BMP-4 concentration in males and Est.VAT Area was risk factor of BMP-4 levels in females. 4) BMP-4 levels were significantly higher in the obesity with slightly increased thyroid stimulating hormone(TSH) than the obesity without slightly increased TSH (902.08 ± 354.74 pg/ml vs. 720.24 ± 306.41 pg/ml, P < 0.05). 5) Exenatide treatment leads to a significant decreased in BMP-4 from 860.05 ± 352.65 pg/ml to 649.44 + 277.49 pg/ml independent of weight loss(P < 0.05). Conclusion BMP-4 levels were associated with the visceral adipose tissue and may play a certain role in fat distribution and subclinical hypothyroidism in obesity. Exenatide treatment reduced BMP-4 levels independent of weight loss. Trial registration Clinicaltrials.gov Identifier: NCT02118376, Registered 16 April.

Abstract
Objective. Recent studies have shown that hyperuricemia (HUA) is associated with hypertension, dyslipidemia, insulin resistance, and metabolic syndrome (MetS). We aimed to examine the relationship of serum UA with Acanthosis nigricans (AN) and related metabolic indices in obese patients. Methods. A cross-sectional study with 411 obese patients recruited from our department was analyzed in this study. Weight, body mass index (BMI), UA, lipid profile, liver function, and renal function were measured in all participants. Oral glucose tolerance tests were performed, and serum glucose, insulin, and C peptide were measured at 0, 30, 60, 120, and 180 min. Results. AN group had higher serum UA levels than OB group. Circulating UA levels were associated with BMI, dyslipidemia, hypertension, IR, and AN. In logistic regression analyses (multivariable-adjusted), a high serum UA level was associated with high odds ratios (ORs) (95% confidence interval [CI]) for AN in females (ORs = 3.00 and 95% CI [1.02-8.84]) and males (ORs = 6.07 and 95% CI [2.16-17.06]) in the highest quartile (Q4) of serum UA. Conclusions. Serum UA levels were positively associated with multiple metabolic abnormalities including obesity, hypertension, hyperglycemia, hyperlipidemia, and AN and may be an important risk factor in the development of AN; further evidences in vitro and in vivo are needed to investigate the direct or indirect relationship.

Abstract
Ketosis in patients with type 2 diabetes mellitus (T2DM) is overlooked due to atypical symptoms. The objective of this study is to evaluate the value of hemoglobin A1c (HbA1c) as a screening tool for ketosis in T2DM patients. This retrospective study consisted of 253 T2DM patients with ketosis at Shanghai 10th People’s Hospital during a period from January 1, 2011 to June 30, 2015. A control group consisted of 221 T2DM patients without ketosis randomly selected from inpatients during the same period. Receiver operating characteristic curve (ROC) analysis was used to examine the sensitivity and specificity of HbA1c as an indicator for ketosis. Higher HbA1c levels were correlated with ketosis. In patients with newly diagnosed T2DM, the area under the curve (AUC) was 0.832, with 95% confidence interval (CI) 0.754–0.911. The optimal threshold was 10.1% (87 mmol/mol). In patients with previously diagnosed T2DM, the AUC was 0.811 (95% CI: 0.767–0.856), with an optimal threshold of 8.6% (70 mmol/mol). HbA1c is a potential screening tool for ketosis in patients with T2DM. Ketosis is much more likely with HbA1c values at ≥10.1% in patients with newly diagnosed T2DM and HbA1c values at ≥8.6% in patients with previously diagnosed T2DM.

Abstract
Background Melatonin can regulate lipid metabolism, increase insulin sensitivity, regulate glucose metabolism and reduce body weight. This study is aimed to determine the effects and mechanism of action of melatonin on non-alcoholic fatty liver disease (NAFLD) in high-fat-diet (HFD) induced obese mice. Methods NAFLD was induced by HFD in C57BL/6 mice. A total of 24 mice were randomly assigned to 4 groups. Groups A and B were fed with HFD for 36 weeks while groups C and D were fed with a regular diet (RD). During the last 12 weeks, Groups A and C were treated with 10 mg/kg melatonin while Groups B and D were treated with water in the same volume by intragastric administration. Body and liver weight, blood glucose, serum transaminases and lipid levels, and markers of hepatic inflammation were measured. Histological analyses were also performed on liver tissue. Results After 12 weeks of treatment with melatonin, body weights (Group A: before 53.11 ± 0.72 vs after 12w treatment 39.48 ± 0.74) and liver weights (A 1.93 ± 0.09 g vs B 2.92 ± 0.19 g vs C 1.48 ± 0.09 g vs D 1.49 ± 0.10 g), fasting plasma glucose, alanine transaminase (A 24.33 ± 11.90 IU/L vs B 60.80 ± 10.18 IU/L vs C 13.01 ± 3.49 IU/L vs D 16.62 ± 2.00 IU/L), and low-density cholesterol (A 0.24 ± 0.06 mmol/L vs B 1.57 ± 0.10 mmol/L vs C 0.28 ± 0.06 mmol/L vs D 0.29 ± 0.03 mmol/L) were significantly decreased in HFD mice. HFD fed mice treated with melatonin showed significantly less liver steatosis. Treatment of HFD fed mice with melatonin led to a significant decrease in the expression of TNF-α, IL-1β, and IL-6 measured using quantitative real-time polymerase chain reaction (qRT-PCR). HFD fed mice demonstrated increased phosphorylation of P38 and JNK1/2, which was reduced by melatonin treatment. Conclusions The study concluded that melatonin could improve NAFLD by decreasing body weight and reduce inflammation in HFD induced obese mice by modulating the MAPK-JNK/P38 signaling pathway.

Abstract
Glutathione S-transferase P1 (GSTP1) and X-ray repair cross-complementing group 1 (XRCC1) genetic variations may in-fluence the efficacy of chemotherapy in various cancers. We investi-gated the possible roles of GSTP1 Ile105Val and XRCC1 Arg194Trp, and Arg399Gln gene polymorphisms in the prognosis of advanced non-small cell lung carcinoma (NSCLC) patients with cisplatin-based chemotherapy. Between January 2010 and December 2012, this study consecutively recruited 141 patients with advanced NSCLC from the First People's Hospital of Yunnan Province. Logistic regression analy-sis showed that individuals carrying the GG genotype were associated with a better response to chemotherapy than those with the wide-type genotype, with an adjusted odds ratio (95% confidence interval, CI) of 4.07 (1.06-25.06). Moreover, we observed that the AA genotype of XRCC1 Arg399Gln was correlated with a greater complete response + partial response to chemotherapy than that with the GG genotype (odds ratio = 2.71, 95%CI = 1.13-10.08). Based on the Cox hazard proportional model, the GG genotype of GSTP1 Ile105Val was found to be associated with a lower risk of death from all causes as compared to that with the AA genotype (hazard ratio = 0.07, 95%CI = 0.01-0.34). In summary, we suggest that GSTP1 Ile105Val and XRCC1 Arg399Gln polymorphisms could influence the response to chemotherapy and sur-vival of advanced NSCLC.

Abstract
Objective. We aimed to investigate the relationship between FGF21 and obesity-related acanthosis nigricans (AN). Methods. 40 obese patients without AN (OB group), 40 obese patients with AN (AN group), and 40 healthy volunteers (control group, CON) were included in this study. Weight, BMI, lipid profile, FFA, UA, and CRP were measured in all participants. Oral glucose tolerance tests (OGTT) were performed and serum glucose and plasma insulin were measured. Serum FGF21 was measured by ELISA. Results. Compared with OB group, AN group had higher levels of fasting insulin and homeostasis model of assessment for insulin resistance (HOMA-IR) (P < 0.05), but lower serum levels of blood glucose. The difference of FGF21 among three groups was significant and AN group showed the highest serum level of FGF21 (P < 0.05). Serum FGF21 was most positively correlated with fasting insulin and HOMA-IR. Multiple logistic analysis showed that FGF21 was the independent risk factor for AN (OR 4.550; 95% CI 1.054-19.635; P = 0.042). Conclusion. AN patients had more serious hyperinsulinemia but better serum levels of blood glucose than OB. Increased FGF21 is associated with AN in obese patients and may be considered as compensatory response to the decreased insulin sensitivity.

Abstract
Type 2 diabetes (T2D) is characterized by β-cell dedifferentiation, but underlying mechanisms remain unclear. The purpose of the current study was to explore the mechanisms of β-cell dedifferentiation with and without long-term control of calorie intake. We used a diabetes mouse model (db/db) to analyze the changes in the expression levels of β-cell-specific transcription factors (TFs) and functional factors with long-term caloric restriction (CR). Our results showed that chronic euglycemia was maintained in the db/db mice with long-term CR intervention, and β-cell dedifferentiation was significantly reduced. The expression of Glut2, Pdx1, and Nkx6.1 was reversed, while MafA expression was significantly increased with long-term CR. GLP-1 pathway was reactivated with long-term CR. Our work showed that the course of β-cell dedifferentiation can intervene by long-term control of calorie intake. Key β-cell-specific TFs and functional factors play important roles in maintaining β-cell differentiation. Targeting these factors could optimize T2D therapies.

Abstract
OBJECTIVE Acanthosis nigricans (AN) is proved to be a skin phenotype of hyperinsulinemia especially in obese patients. Irisin is a new myokine which plays an important role in metabolic disorders, such as obesity, insulin resistance, and type 2 diabetes. The role of irisin in the development of AN-related obesity is not yet understood. In this study, we aimed to investigate the relationship between irisin and AN-related obesity. Patients & Measurements: 30 obese patients without AN (OB group), 30 obese patients with AN (AN group), and 20 age-matched healthy volunteers (control group, CON) were included in this study. Weight, BMI, lipid profile, FFA, UA, and CRP were measured in all participants. Oral Glucose Tolerance tests (OGTT) were performed and serum glucose and plasma insulin were measured at 0, 30, 60,120 and 180 min. The AUC (area under curve) of glucose and insulin was calculated. Serum irisin was measured by ELISA. RESULTS Hyperinsulinemia is found in both AN and OB groups. The AN group had higher levels of insulin but better blood glucose tolerance and insulin response. The difference in irisin levels between the 3 groups was statistically significant, with the AN group showing the highest serum level of irisin. Serum irisin levels were positively correlated with BMI, and fasting insulin. CONCLUSION AN is a state of hyperinsulinmia and has better insulin response and glucose tolerance compared to obese patients without AN. Serum irisin may be a protective factor against impaired beta cell function in obesity with AN.

Abstract
Alendronate (ALN) is a commonly used drug for the treatment of osteoporosis. Atypical femur fractures (AFFs) have been associated with long-term use of ALN and have recently become the subject of considerable attention as ALN use increases. This meta-analysis aimed to determine the relationship between ALN and AFF. The Embase, PubMed, and Cochrane library databases were searched for relevant studies published before November 6, 2014. Studies clearly reporting the relationship between ALN and AFF were selected for our analysis. From these results, the relationship between ALN and AFF was analyzed. Weighted mean differences were calculated using a random-effects model. Five studies were included in this meta-analysis. The results revealed that the use of ALN will not increase the risk of AFF in short term (P>0.05), but there will be a risk of AFF (P<0.05) with long-term (>5 years) use of ALN. These findings indicate that long-term use of ALN is a risk factor for AFF and that more attention should be paid to the clinical applications of ALN.

Abstract
Traditional anti-diabetic drugs may have negative or positive effects on risk of bone fractures. Yet the relationship between the new class glucagon-like peptide-1 receptor agonists (GLP-1 RA) and risk of bone fractures has not been established. We performed a meta-analysis including randomized controlled trials (RCT) to study the risk of bone fractures associated with liraglutide or exenatide, compared to placebo or other active drugs. We searched MEDLINE, EMBASE, and clinical trial registration websites for published or unpublished RCTs comparing the effects of liraglutide or exenatide with comparators. Only studies with disclosed bone fracture data were included. Separate pooled analysis was performed for liraglutide or exenatide, respectively, by calculating Mantel-Haenszel odds ratio (MH-OR). 16 RCTs were identified including a total of 11,206 patients. Liraglutide treatment was associated with a significant reduced risk of incident bone fractures (MH-OR=0.38, 95% CI 0.17-0.87); however, exenatide treatment was associated with an elevated risk of incident bone fractures (MH-OR=2.09, 95% CI 1.03-4.21). Publication bias and heterogeneity between studies were not observed. Our study demonstrated a divergent risk of bone fractures associated with different GLP-1 RA treatments. The current findings need to be confirmed by future well-designed prospective or RCT studies.
