Abstract
Objective: To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021. Methods: A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children. Results: The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M (Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 (χ2trend=111.427, P<0.001). The median of urinary iodine concentration M (Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [M (Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [M (Q1, Q3): 173.00 (113.00, 250.30) μg/L] (P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95%CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95%CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95%CI: 2.64%-3.10%), 588/20 530] (P=0.001). Conclusion: From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

Abstract
Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome in which tumor-induced osteochondrosis is a metabolic bone disease caused by increased renal excretion of phosphorus due to excessive secretion of fibroblast growth factor 23 (FGF23) by tumor tissue. We report here a rare case of TIO in which the tumor was found in the hyoid body and the patient had tertiary hyperparathyroidism. The patient's symptoms did not improve after removal of the tumor from the hyoid body, and the patient's hypophosphatemia was gradually improved after subsequent removal of the left parathyroid gland. TIO derived from the tongue tumor is very rare, and also subsequent tertiary hyperparathyroidism is even rarer. This report helps to improve the understanding of TIO and provides reference in the diagnosis and treatment of TIO.

Abstract
PURPOSE/OBJECTIVE(S) Widespread use of intensity modulated radiotherapy (IMRT) has improved the tumor control rate of nasopharyngeal carcinoma (NPC). However, nearly 20% of the patients with local-advanced NPC would relapse after precise irradiation and 80% of the recurrent lesions occur within the high dose field, suggesting that there are radiation-resistant cancer cell subsets within the tumor. In this context, identification and contouring of radiation resistance region of NPC for dose escalation at primary IMRT could be advantageous. In this work, we proposed a two-step radiomics workflow to predict local relapse and the recurrent region of NPC before primary IMRT. MATERIALS/METHODS In this single-center, retrospective study, pre-treatment magnetic resonance (MR) sequences of T1-weighted imaging (T1-w) and contrast-enhanced T1-weighted imaging (CET1-w) were collected from 800 patients of newly diagnosed and non-metastatic NPC between April 2009 and December 2015. The primary gross tumor volume (GTVp) of all patients and the actual recurrent lesion (GTVr) of patients who suffered from local recurrence were manually contoured for further analysis. A two-step complete radiomics workflow was designed to predict tumor recurrence and segment the region. First, least absolute shrinkage and selection operator (LASSO) was utilized for radiomics features selection of GTVp and support vector machine (SVM) was adopted to predict the recurrence. If the model predicts a recurrence, then the workflow utilizes an improved 3D U-Net to segment the recurrent region. Area under receiver operating characteristic curve (ROC-AUC) was used to evaluate the performance of tumor recurrence prediction, and Dice similarity coefficient (DSC) was used to assess the consistence between the actual and predicted GTVr. RESULTS Of 800 NPC patients, 95 (11.9%) patients developed in-field local recurrence. For recurrence risk prediction, the SVM ensemble model (T1-w+CET1-w) was selected for further application with higher sensitivity. The average ROC-AUC, specificity, sensitivity of the SVM ensemble model in a 5-fold cross-validation and in the independent test set of 160 patients were 0.922, 0.922, 0.777 and 0.928, 0.915, 0.737, respectively. Moreover, for recurrent region segmentation, the multi-modality (T1-w+CET1-w) model was superior to the single-modality (T1-w or CET1-w) model. In an independent test set of 15 patients, the DSC, sensitivity and 95% Hausdorff Distance between actual and predicted GTVr was 0.549±0.176, 0.696±0.118 and 9.813±4.788 which was superior to 0.444±0.188, 0.497±0.218 and 12.047±5.361 of original 3D U-Net. CONCLUSION The proposed two-step radiomics workflow showed a good performance in predicting tumor recurrence of NPC. The predicted location of the recurrence lesion was all accurate, but there was still a certain difference between the volume of the automated delineated and actual GTVr, which needed to be further optimized to be used as biological tumor volume.

Abstract
PURPOSE/OBJECTIVE(S) PALACE-1 trial has confirm that the addition of pembrolizumab to neoadjuvant chemoradiotherapy (NCRT) improves the pathological complete response(pCR) for esophageal squamous cell carcinoma (ESCC), which might be a novel treatment strategy for ESCC. In the present study, we aim to establish a machine learning model to predict the local response to NCRT+ pembrolizumab for ESCC by using pretreatment 18-fluorodeoxyglucose positron emission tomography (FDG PET) and contrast-enhanced plan CT images. MATERIALS/METHODS A total of 65 cases treated with NCRT+ pembrolizumab followed by surgery were prospectively enrolled for analysis from 2019-2022. Each patient contains a contrast-enhanced plan CT and FDG PET images. 52 patients were randomly divided into training set and 13 patients were used as test set. The Extraction of radiomics features was performed using an open-source Python library PyRadiomics automatically. Features were computed according to the radiologist-drawn ROIs on both CT and PET images. In the feature selection stage least absolute shrinkage and selection operator (LASSO) was utilized on CT features and PET features separately. Four different machine learning models were implemented: Support Vector Machine (SVM), Logistic Regression (LR), Random Forest (RF) and XGBoost (XGB). The features selected by LASSO regression were used as model input and the output of the model is "pCR" or "non-pCR". To find the optimal parameter, the 5-fold cross-validation method was used in the training stage. In this study, we use accuracy, sensitivity and specificity as the metrics to evaluate the performance of the model on the testing cohort. The predictive performance of the model was assessed using the area under curve (AUC) of the receiver operating characteristics curve (ROC). RESULTS Of the 65 cases treated with NCRT+pembrolizumab, 35 patients archived pCR (53.8%), and 30 archived non-pCR. 1684 radiomics features were extracted from each case, and half of them (842 features) were from CT and others were from PET. Among the machine learning models mentioned above SVM achieves the most promising performance on the evaluation metrics. Accuracy, sensitivity, specificity and AUC score on test set were 0.692, 0.833, 0.571 and 0.786 for CT features and 0.615, 0.667, 0.571 and 0.762 for PET features, respectively. For CT+FDG PET fused features accuracy, sensitivity, specificity and AUC score on test set were 0.769, 0.667, 0.857 and 0.833. CONCLUSION In this study, we performed several different machine learning models to predict the response to NCRT+ pembrolizumab among ESCC based on the extracted radiomics features from CT and FDG PET images. The best-performing model based on radiomics features of CT and PET images could identify non-pCR to NCRT + pembrolizumab in EC patients.

Abstract
BACKGROUND Oxidative stress is recognized as a key factor in the induction of endothelial dysfunction in diabetes. However, the specific mechanisms have not been fully elucidated. We herein hypothesized that ubiquitin-like containing PHD and RING finger domains 1 (UHRF1) might have a role in oxidative stress-induced endothelial cell (EC) apoptosis in diabetes. METHODS Western blot, qPCR, wound healing assay, apoptosis assay, reactive oxygen species (ROS) detection, dual-luciferase reporter assay, methylation-specific PCR, bisulfite sequencing PCR and chromatin immunoprecipitation assay were performed. RESULTS UHRF1 expression levels were significantly decreased in endothelial colony-forming cells derived from peripheral blood of participants with type 2 diabetes compared with individuals without diabetes. ECs treated with high glucose, palmitate or hydrogen peroxide in vitro also exhibited decreased UHRF1 protein levels. Silencing of UHRF1 led to decreased migration ability and increased apoptosis and ROS production in ECs, which might be related to impaired Kelch-like ECH-associated protein 1 (KEAP1)/nuclear factor erythroid 2-related factor 2 (NRF2)/haeme oxygenase-1 pathway. Mechanistically, UHRF1 is closely implicated in epigenetic regulation of chromatin modification status at KEAP1 genomic locus via histone acetylation. NRF2 down-regulation in turn inhibits UHRF1 protein level, which might be due to increased ROS generation. CONCLUSION Diabetes-induced oxidative stress can mediate down-regulation of UHRF1, which enhances ROS production by regulating KEAP1/p-NRF2 pathway through histone acetylation and might also form a self-perpetuating feedback loop with KEAP1/p-NRF2 to further promote oxidative stress-induced apoptosis of ECs in diabetes.

Abstract
Diabetic foot ulcers are a serious complication of diabetes, with high mortality and a lack of effective clinical treatment, which leads to a considerable financial burden. Pien-Tze-Huang (PZH) is a Chinese traditional medicine with a long history that has been found to be an effective and convenient treatment for inflammatory diseases such as skin abscesses and ulcers. In this study, we assessed the effects of PZH on diabetic wounds and the underlying mechanisms. The wounds were established on the backs of streptozotocin-induced type 1 diabetic rats and type 2 diabetic mouse models. We found that PZH treatment used locally or by gavage significantly promoted wound healing, accelerated re-epithelialization and vasculature in the wound tissue, upregulated the expression of the growth factors VEGF-A, PDGF, and EGF, and activated the Nrf2/ARE pathway in the wound tissue. In vitro assays showed that PZH improved the proliferation, migration and angiogenic function of human umbilical vein endothelial cells (HUVECs) cultured in palmitic acid, reduced the expression of the apoptotic proteins p53, Bax, and cleaved-caspase3, and activated Nrf2/ARE signaling; however, these protective effects were abrogated after Nrf2 was knocked down by specific siRNA. In addition, the levels of the serum inflammatory cytokines IL-1β, TNF-α, and IL-6 were reduced after PZH gavage treatment. In conclusion, the positive role of PZH in diabetic wound healing might be related to the activation of the Nrf2/ARE pathway to regulate the level of oxidative stress in vivo and increase the expression of growth factors to improve angiogenesis.

Abstract
OBJECTIVE This phase 3 confirmatory diabetes mellitus treatment study compared the safety and efficacy of Rapilin and NovoRapid insulin asparts in combination with metformin. METHODS This 24-week, open-label, randomized, active-controlled, noninferiority phase 3 confirmatory study conducted across centers in China aimed to enroll patients with type 2 diabetes mellitus and blood sugar glucose inadequately controlled by oral antidiabetic drugs. Randomized patients received subcutaneous mealtime Rapilin or NovoRapid (3:1) injections, with metformin. The primary objectives were to demonstrate noninferiority (margin of 0.4%) in HbA1c change from baseline and compare safety profiles of Rapilin versus NovoRapid after 24 weeks. Secondary outcomes included 2-h postprandial plasma glucose (PPG), fasting plasma glucose (FPG), and patients achieving HbA1c <7.0% and ≤6.5%. RESULTS 590 patients with type 2 diabetes mellitus were randomized to Rapilin (n = 441) and NovoRapid (n = 149) groups. After 24 weeks, the mean HbA1c change from baseline was -2.20% (Rapilin) and -2.32% (NovoRapid); the estimated treatment difference based on least-square means was 0.04% (95% CI: -0.17, 0.26), meeting the noninferiority criteria for Rapilin versus NovoRapid. Comparable improvements were reported for mean 2-hour PPG (6.14 and 6.29 mmol/L), FPG (2.02 and 1.70 mmol/L), and patients with HbA1c <7.0% (52.6% and 51.0%) and ≤6.5% (34.2% and 30.9%), in the Rapilin and NovoRapid groups, respectively, with no significant safety or immunogenicity outcome differences. CONCLUSIONS Rapilin demonstrated non-inferior glycemic control, and matching safety and immunogenicity to NovoRapid in patients with type 2 diabetes mellitus also receiving metformin over 24 weeks.

Abstract
OBJECTIVE To explore the transcriptional regulation mechanism and biological function of low expression of vasoactive intestinal peptide receptor 1 (VIPR1) in hepatocellular carcinoma (HCC). METHODS We constructed plasmids carrying wild-type VIPR1 promoter or two mutant VIPR1 promoter sequences for transfection of the HCC cell lines Hep3B and Huh7, and examined the effect of AP-2α expression on VIPR1 promoter activity using dual-luciferase reporter assay. Pyrosequencing was performed to detect the changes in VIPR1 promoter methylation level in HCC cells treated with a DNA methyltransferase inhibitor (DAC). Chromatin immunoprecipitation was used to evaluate the binding ability of AP-2α to VIPR1 promoter. Western blotting was used to assess the effect of AP-2α knockdown on VIPR1 expression and examine the differential expression of VIPR1 in the two cell lines. The effects of VIPR1 overexpression and knockdown on the proliferation, cell cycle and apoptosis of HCC cells were analyzed using CCK8 assay and flow cytometry. We also observed the growth of HCC xenograft with lentivirus-mediated over-expression of VIPR1 in nude mice. RESULTS Compared with the wild-type VIPR1 promoter group, co-transfection with the vector carrying two promoter mutations and the AP-2α-over-expressing plasmid obviously restored the luciferase activity in HCC cells (P < 0.05). DAC treatment of the cells significantly decreased the methylation level of VIPR1 promoter and inhibited the binding of AP-2α to VIPR1 promoter (P < 0.01). The HCC cells with AP-2α knockdown showed increased VIPR1 expression, which was lower in Huh7 cells than in Hep3B cells. VIPR1 overexpression in HCC cells caused significant cell cycle arrest in G2/M phase (P < 0.01), promoted cell apoptosis (P < 0.001), and inhibited cell proliferation (P < 0.001), while VIPR1 knockdown produced the opposite effects. In the tumor-bearing nude mice, VIPR1 overexpression in the HCC cells significantly suppressed the increase of tumor volume (P < 0.001) and weight (P < 0.05). CONCLUSION VIPR1 promoter methylation in HCC promotes the binding of AP-2α and inhibits VIPR1 expression, while VIPR1 overexpression causes cell cycle arrest, promotes cell apoptosis, and inhibits cell proliferation and tumor growth.

Abstract
Stem cells and progenitor cells have been identified as potential new therapeutic options for severe limb ischemia to induce angiogenesis, and hyaluronic acid (HA) is commonly applied as a biomaterial in tissue engineering. However, the efficiency of HA combined with human umbilical cord blood-derived endothelial colony forming cells (ECFCs) and human umbilical-derived mesenchymal stem cells (MSCs) on angiogenesis is unclear. In the present study, we showed that HA promoted angiogenesis induced by MSCs-ECFCs in Matrigel plugs and promoted blood perfusion of murine ischemic muscles. Laser confocal microscopy revealed that human-derived cells grew into the host vasculature and formed connections, as shown by mouse-specific CD31+/human-specific CD31+ double staining. In vitro assays revealed that HA supported cell proliferation and migration, enhanced CD44 expression and reduced microRNA (miR)-139-5p expression. Further analysis revealed that miR-139-5p expression was negatively regulated by CD44 in ECFCs. Flow cytometry assays showed that HA increased CD31 positive cells proportion in MSC-ECFC and could be reversed by miR-139-5p mimics transfection. Moreover, the improvement of MSC-ECFC proliferation and migration induced by HA could be blocked by upregulation of miR-139-5p expression. In conclusion, HA facilitates angiogenesis of MSCs-ECFCs, and this positive effect be associated with activation of the CD44/miR-139-5p pathway, providing a promising strategy for improving severe limb ischemia.

Abstract
AIMS/HYPOTHESIS Glucagon-like peptide 1 receptor agonists (GLP-1 RA) such as exenatide are used as monotherapy and add-on therapy for maintaining glycaemic control in patients with type 2 diabetes mellitus. The current study investigated the safety and efficacy of once-weekly PB-119, a PEGylated exenatide injection, in treatment-naive patients with type 2 diabetes. METHODS In this Phase II, randomised, placebo-controlled, double-blind study, we randomly assigned treatment-naive Chinese patients with type 2 diabetes in a 1:1:1:1 ratio to receive subcutaneous placebo or one of three subcutaneous doses of PB-119 (75, 150, and 200 μg) for 12 weeks. The primary endpoint was the change in HbA1c from baseline to week 12, and other endpoints were fasting plasma glucose, 2 h postprandial glucose (PPG), and proportion of patients with HbA1c < 53 mmol/mol (<7.0%) and ≤48 mmol/mol (≤6.5%) at 2, 4, 8 and 12 weeks of treatment. Safety was assessed in all patients who received at least one dose of study drug. RESULTS We randomly assigned 251 patients to one of the four treatment groups (n = 62 in placebo and 63 each in PB-119 75 μg, 150 μg and 200 μg groups). At the end of 12 weeks, mean differences in HbA1c in the treatment groups were -7.76 mmol/mol (95% CI -9.23, -4.63, p < 0.001) (-0.72%, 95% CI -1.01, -0.43), -12.89 mmol/mol (95% CI -16.05, -9.72, p < 0.001) (-1.18%, 95% CI -1.47, -0.89) and -11.14 mmol/mol (95% CI -14.19, -7.97, p <0 .001) (-1.02%, 95% CI -1.30, -0.73) in the 75 μg, 150 μg and 200 μg PB-119 groups, respectively, compared with that in the placebo group after adjusting for baseline HbA1c. Similar results were also observed for other efficacy endpoints across different time points. There was no incidence of treatment-emergent serious adverse event, severe hypoglycaemia or death. CONCLUSIONS/INTERPRETATION All tested PB-119 doses had superior efficacy compared with placebo and were safe and well tolerated over 12 weeks in treatment-naive Chinese patients with type 2 diabetes. TRIAL REGISTRATION ClinicalTrials.gov NCT03520972 FUNDING: The study was funded by National Major Scientific and Technological Special Project for Significant New Drugs Development and PegBio.

Abstract
During vertebrate development, the cardiovascular system begins operating earlier than any other organ in the embryo. Endothelial cell (EC) forms the inner lining of blood vessels, and its extensive proliferation and migration are requisite for vasculogenesis and angiogenesis. Many aspects of cellular biology are involved in vasculogenesis and angiogenesis, including the tip versus stalk cell specification. Recently, epigenetics has attracted growing attention in regulating embryonic vascular development and controlling EC differentiation. Some proteins that regulate chromatin structure have been shown to be directly implicated in human cardiovascular diseases. Additionally, the roles of important EC signaling such as vascular endothelial growth factor and its receptors, angiopoietin-1 and tyrosine kinase containing immunoglobulin and epidermal growth factor homology domain-2, and transforming growth factor-β in EC differentiation during embryonic vasculature development are briefly discussed in this review. Recently, the transplantation of human induced pluripotent stem cell (iPSC)-ECs are promising approaches for the treatment of ischemic cardiovascular disease including myocardial infarction. Patient-specific iPSC-derived EC is a potential new target to study differences in gene expression or response to drugs. However, clinical application of the iPSC-ECs in regenerative medicine is often limited by the challenges of maintaining cell viability and function. Therefore, novel insights into the molecular mechanisms underlying EC differentiation might provide a better understanding of embryonic vascular development and bring out more effective EC-based therapeutic strategies for cardiovascular diseases.

Abstract
Methicillin‐resistant Staphylococcus aureus (MRSA) with reduced sensitivity to vancomycin (VAN) has caused many clinical cases of VAN treatment failure, but the molecular mechanism underlying the reduced sensitivity to VAN is still unclear. We isolated a heterogeneous VAN‐intermediate Staphylococcus aureus (hVISA), which was also a MRSA strain with reduced sensitivity to VAN. To investigate the molecular mechanism underlying the reduced sensitivity to VAN exhibited by the hVISA strain, we compared the hVISA strain with a VAN‐sensitive MRSA strain, known as the N315 strain. The images captured by transmission electron microscopy showed that the cell wall of the hVISA strain was significantly thicker than that of the N315 strain (36·72 ± 1·04 nm vs 28·15 ± 1·25 nm, P < 0·05), and the results of real‐time quantitative PCR analysis suggested that the expression levels of the cell wall thickness related genes (glmS, vraR/S, sgtB, murZ and PBP4) of the hVISA strain were significantly higher than those of the N315 strain (P < 0·05). In conclusion, this study indicated that the upregulation of the expression of the genes related to cell wall synthesis might be the molecular mechanism underlying the cell wall thickening of the hVISA strain and might be related to its resistance to VAN.

Abstract
AIM To assess the efficacy and safety of polyethylene glycol loxenatide (PEX168), a new glucagon-like peptide-1 receptor agonist, as an add-on to metformin therapy in Chinese patients with type 2 diabetes (T2D). MATERIALS AND METHODS This was a multicentre, randomized, double-blind, placebo-controlled phase 3b trial. After metformin monotherapy (≥1500 mg/day) for 8 weeks or more, patients with uncontrolled T2D (HbA1c of 7.0%-10.5%) from 44 sites were randomized (1:1:1) to metformin + placebo, metformin + PEX168 100 μg, and metformin + PEX168 200 μg. The core treatment period lasted for 24 weeks, followed by a 28-week extension period. The primary endpoint was the change in HbA1c levels at week 24. The main secondary endpoint was the proportion of patients with an HbA1c of less than 7.0% at week 24. RESULTS The least-square mean (standard error) change in HbA1c levels was significantly greater (P < .001 for superiority) in the PEX168 groups (-1.16% [0.08%] and -1.14% [0.08%] with 100 and 200 μg, respectively) than in the placebo group (0.35% [0.08%]). The proportion of patients with an HbA1c of less than 7.0% at week 24 was significantly higher in the PEX168 100 μg (37.4%) and PEX168 200 μg (40.6%) groups than in the placebo group (16.8%; both P < .001). The gastrointestinal reactions were mild; the risks of hypoglycaemia and weight gain did not increase. Anti-PEX168 antibodies were noted in less than 2% of patients. No treatment-emergent serious adverse events occurred. CONCLUSION The subcutaneous injection of PEX168 once a week can effectively, continuously and safely improve HbA1c levels in patients with T2D when combined with metformin.

Abstract
Multiple endocrine neoplasia-IIb (MEN-IIb) is a rare hereditary autosomal dominant syndrome caused by mutations in the RET proto-oncogene. It's characterized by medullary thyroid carcinoma (MTC), pheochromocytoma (PHEO), mucosal neuromas, and Marfanoid habitus. Because of the rarity of MEN-IIb and finiteness of clinical cognition, the majority of the patients suffer a delayed diagnosis. A MEN-IIb patient with the lingual mucosal neuromas since childhood was admitted in the Third Xiangya Hospital of Central South University in November, 2018. He had surgical history of mitral valve prolapse and spinal deformity. He was diagnosed with MTC and PHEO at the age of 22 and 28, respectively, and received surgical treatments. Sequencing of RET gene revealed a de novo heterozygous p.M918T mutation in the patient. Being aware of the unique clinical phenotype and screening of RET gene mutation may lead to the early diagnosis and better long-term outcome for MEN-IIb.

Abstract
Treatment-induced neuropathy is an distinct, acute form of neuropathic pain which often occur shortly after initiation of intensive glycemic control and is characterized by excruciating neuropathic pain. It is a rare form of diabetic neuropathy and easy to be misdiagnosed. Clinical characteristics were analyzed based on two cases of treatment-induced neuropathy in diabetes accepted by the Third Xiangya Hospital of Central South University. It is proposed that strict glycemic control may lead to the occurrence of the disease. At Present, the pathogenesis is still unclear. Besides, the morbidity is much higher than we expected. It is important to improve the doctors awareness of this disease and avoid the the disease through carful glycemic control.

Abstract
Many recent studies have proved that ubiquitin-like with PHD and RING finger domains 1 (UHRF1) is an important nuclear protein associated with tumorigenesis, which plays a significant role in epigenetic regulation, especially in DNA methylation and histone methylation. For its particular domains, UHRF1 plays a critical role in biological behaviors including cell proliferation, cell cycle, and apoptosis. Overexpression of UHRF1 in various tumors is closely associated with the angiogenesis in tumors. This paper will provide a review of the regulation of UHRF1 in DNA methylation and histone methylation, and discuss the potential epigenetic role of UHRF1 in angiogenesis.

Abstract
INTRODUCTION Metabolic surgery is an effective treatment for type 2 diabetes (T2D). At present, there is no authoritative standard for predicting postoperative T2D remission in clinical use. In general, East Asian patients with T2D have a lower body mass index and worse islet function than westerners. We aimed to look for clinical predictors of T2D remission after metabolic surgery in Chinese patients, which may provide insights for patient selection. METHODS Patients with T2D who underwent metabolic surgery at the Third Xiangya Hospital between October 2008 and March 2017 were enrolled. T2D remission was defined as an HbA1c level below 6.5% and an FPG concentration below 7.1 mmol/L for at least one year in the absence of antidiabetic medications. RESULTS (1) Independent predictors of short-term T2D remission (1-2 years) were age and C-peptide area under the curve (C-peptide AUC); independent predictors of long-term T2D remission (4-6 years) were C-peptide AUC and fasting plasma glucose (FPG). (2) The optimal cutoff value for C-peptide AUC in predicting T2D remission was 30.93 ng/ml, with a specificity of 67.3% and sensitivity of 75.8% in the short term and with a specificity of 61.9% and sensitivity of 81.5% in the long term, respectively. The areas under the ROC curves are 0.674 and 0.623 in the short term and long term, respectively. (3) We used three variables (age, C-peptide AUC, and FPG) to construct a remission prediction score (ACF), a multidimensional 9-point scale, along which greater scores indicate a better chance of T2D remission. We compared our scoring system with other reported models (ABCD, DiaRem, and IMS). The ACF scoring system had the best distribution of patients and prognostic significance according to the ROC curves. CONCLUSION Presurgery age, C-peptide AUC, and FPG are independent predictors of T2D remission after metabolic surgery. Among these, C-peptide AUC plays a decisive role in both short- and long-term remission prediction, and the optimal cutoff value for C-peptide AUC in predicting T2D remission was 30.93 ng/ml, with moderate predictive values. The ACF score is a simple reliable system that can predict T2D remission among Chinese patients.

Abstract
BACKGROUND Multiple symmetric lipomatosis (MSL) is a rare disease showing chronic progression of multiple, symmetrical, and non-encapsulated subcutaneous lipoma. The cause of the disease remains unknown. PATIENTS AND METHODS This study reported and summarized 13 sporadic cases of Type I MSL patients in terms of histopathology and cellular and molecular biology and assessed the CBLB c.197A>T mutation in the IRS1-PI3K-Akt pathway. RESULTS The clinical data showed that these 13 Type I patients were all male with a mean age of 57.0 ± 6.6 years old and consumed alcohol heavily. The laboratory tests revealed that most of the patients had hyperuricemia, diabetes, hyperinsulinemia, or insulin resistance; however, their blood lipid levels were close to a normal range. The imaging data exhibited lipomas that only occurred subcutaneously but not viscerally, ie, Types Ia (15.4%), Ib (30.8%), and Ic (53.8%). The molecular analyses of adipocytes of isoprenaline stimulated human adipose tissue-derived mesenchymal stromal cells (hADSCs) isolated from the adipose tissue lipoma-like masses (ATLLM) demonstrated that these adipocytes did not express UCP-1. The Cbl proto-oncogene B (CBLB), an E3 ubiquitin-protein ligase, was associated with insulin resistance and obesity and was mutated (ie, CBLB c.197A>T) in four MSL patients after the whole genome and Sanger sequencing of the blood samples. Furthermore, the CBLB c.197A>T mutation induced hADSC resistance to insulin by inactivation of the IRS-1-PI3K-AKT pathway. CONCLUSION This study analyzed clinical, histopathological, and cellular and molecular biological characterizations of 13 Type I MSL patients and identified the CBLB c.197A>T heterozygous mutation that could be responsible for MSL metabolic dysfunction or even MSL development.

Abstract
Providing a better understanding of the risk factors for amputation in this particular region, Hunan province, in China might help patients with diabetic foot ulcers receive timely and appropriate medical care and help prevent amputation. Diabetic foot ulcer patients referred to the Third Xiangya Hospital during the period between December 2014 and September 2018 were enrolled. Participants who underwent amputations and received conservative treatments were compared using univariate and multivariate analyses to identify the independent predictors of amputation. Those who required amputation presented significantly higher levels of white blood cell counts, platelet counts, erythrocyte sedimentation rate, C-reactive protein, and glycated haemoglobin (HbA1c) levels. However, levels of haemoglobin, postprandial plasma C-peptide, triglyceride, high-density lipoprotein cholesterol, albumin, and uric acid were decreased in patients with amputations. Patients with more advanced Wagner grades had much higher rates of amputation. Multivariable-adjusted odds ratios in stepwise logistic regression model was 1.317 for HbA1c (95% CI: 1.015-1.709), 0.255 for triglyceride (95% CI: 0.067-0.975), and 20.947 for Wagner grades (95% CI: 4.216-104.080). Independent risk factors for amputation in these Chinese diabetic foot ulcer patients included an elevated HbA1c level, lower triglyceride level, and higher Wagner grades.

Abstract
NLRP3 inflammasome is a key contributor to obesity-related insulin resistance and type 2 diabetes (T2D). Adenosine monophosphate-activated protein kinase (AMPK) is a principle intracellular energy sensor exerting protective effect against T2D. Strikingly, compound C, an inhibitor of AMPK, considerably inhibited the secretion of IL-1β when THP-1 cells were stimulated with LPS plus palmitic acid (PA). The underlying mechanism was examined with respect to the effect of compound C on NLRP3 inflammasome, a multiprotein complex which controls the processing and production of IL-1β. Interestingly, compound C significantly attenuated the activation of NLRP3 inflammasome. This phenomenon was reproduced in AMPK siRNA-transfected THP-1 cells, indicating that compound C exerts this function despite AMPK knockdown. Also, it significantly suppresses the mitochondria-generated reactive oxygen species (ROS) required for NLRP3 inflammasome activation. In conclusion, compound C was shown to significantly attenuate the NLRP3 inflammasome despite AMPK knockdown, rendering it as the novel target of compound C. Potentially, compound C attenuates NLRP3 inflammasome through the suppression of mitochondrial ROS production. These findings offer initial evidence into compound C as a novel pharmacological agent with significant therapeutic potential in NLRP3 inflammasome-related disorders, including obesity, insulin resistance, and T2D. Thus, further studies are essential to identify the effect of compound C on these diseases in vitro.

Abstract
Nivolumab is an anti-programmed cell death (anti-PD-1) monoclonal antibody, which is a new drug for tumor immunotherapy. A 73-year-old female patient with colorectal cancer 3 years after surgery was treated in the Endocrinology Department of Third Xiangya Hospital, Central South University, who developed severe hypothyroidism resulting from treatment with nivolumab. After 4 months treatment of nivolumab, this patient presented with symptoms such as fatigue, dizziness, jaundice and palpebral edema, with decreased levels of FT3 and FT4 and elevated levels of TSH. Subsequently, nivolumab treatment was terminated. This patient's symptoms were relieved and thyroid function returned to normal after thyroxine replacement therapy. The clinical diagnosis was considered to be nivolumab-induced autoimmune thyroid damage, which was an immune-related adverse reaction in the treatment.

Abstract
OBJECTIVE To investigate the effects of mesenchymal stem cells (MSCs) coated by the extracellular matrix (ECM) on wound healing in diabetic rats. METHODS Mesenchymal stem cells were cocultured with ECM. Cell viabilities were evaluated using MTT assay. The diabetes model was established using both STZ and high-glucose/fat methods in SD rats. A wound area was made on the middle of the rats' back. MSCs or ECM-MSCs were used to treat the rats. HE staining and CD31 immunohistochemistry were used to detect the skin thickness and angiogenesis. Western blotting and qRT-PCR were conducted to determine the level of VEGF-α, PDGF, and EGF. RESULTS It was observed that treatment of ECM had no significant effects on the cell viability of ECM-MSCs. Wound area assay showed that both MSCs and ECM-MSCs could enhance the wound healing of diabetic rats and ECM-MSCs could further promote the effects. Both MSCs and ECM-MSCs could enhance angiogenesis and epithelialization of the wounds, as well as the expression of VEGF-α, PDGF, and EGF in wound tissues, while ECM-MSC treatment showed more obvious effects. CONCLUSION Mesenchymal stem cells coated by the extracellular matrix could promote wound healing in diabetic rats. Our study may offer a novel therapeutic method for impaired diabetic wound healing.

Abstract
OBJECTIVES The aim of this study was to investigate the effects of compound C on an in vivo mouse model of high-fat diet- (HFD-) induced obesity and hepatosteatosis. METHODS C57BL/6 mice were fed with a standard diet (n = 5) for 16 weeks and then injected saline once a day for 4 weeks as the normal chow group. Mice (n = 10) were fed with HFD for 16 weeks to induce obesity and hepatosteatosis and then divided into two groups: HFD + vehicle group injected with the vehicle solution (saline) and HFD + compound C group injected with compound C in saline (5 mg/kg i.p., once a day) for 4 weeks. Liver histology was observed. The expression levels of genes related to lipid metabolism and proinflammation in liver tissue were examined. NLRP3 inflammasome expression in liver tissue was detected by the western blot assay. HepG2 cells were pretreated with compound C and/or AICAR for 1 h and then treated with palmitic acid (PA) for 3 h. The cells were collected, and mRNA levels were determined. RESULTS There was a significant reduction in body-weight gain and daily food intake in the HFD + compound C group compared with the HFD + vehicle group (p < 0.05). The glucose tolerance test (GTT) and insulin tolerance test (ITT) showed that compound C alleviated insulin resistance. Histology analysis showed a significant reduction of hepatic steatosis by compound C. Compound C also significantly decreased fatty acid synthesis genes, while increased fatty acid oxidation genes. Furthermore, compound C significantly reduced the expression of proinflammatory markers and NLRP3 inflammasome (p < 0.05). Compound C enhanced mRNA levels of SOD1, SOD2, catalase, GPx1, and GPx4 and reduced the p-AMPK/AMPK ratio, which were stimulated by palmitic acid (PA). The effect was enhanced by AICAR. CONCLUSION Our data suggest that compound C is a potent NAFLD suppressor and an attractive therapeutic target for hepatic steatosis and related metabolic disorders.

Abstract
Background Gitelman syndrome (GS) is a rare autosomal recessive renal tubular disease, caused by mutations in the SLC12A3 gene, which encodes the renal thiazide-sensitive Na/Cl cotransporter (NCCT) in the distal renal tubule. Case presentation A 23-year-old woman was admitted with limb numbness, recurrent tetany and palpitation. Laboratory tests showed hypokalemic alkalosis, hypomagnesemia, hypocalcemia and secondary hyperaldosteronism, as well as hypocalciuria and transient decreased PTH. Next-generation sequencing detected a novel homozygous mutations c.2039delG in the SLC12A3 gene, and her father and children were all heterozygous carriers. Conclusion We reported a case of GS with a novel homozygous frame-shift mutation of SLC12A3, and reviewed recent literatures about diagnosis, differential diagnosis and treatments. Hypocalcemia in Gitelman syndrome is rare, and may be related to inhibited PTH secretion induced by hypomagnesemia.

Abstract
In amyotrophic lateral sclerosis (ALS), mitochondrial dysfunction and oxidative stress form a vicious cycle that promotes neurodegeneration and muscle wasting. To quantify the disease-stage-dependent changes of mitochondrial function and their relationship to the generation of reactive oxygen species (ROS), we generated double transgenic mice (G93A/cpYFP) that carry human ALS mutation SOD1G93A and mt-cpYFP transgenes, in which mt-cpYFP detects dynamic changes of ROS-related mitoflash events at individual mitochondria level. Compared with wild type mice, mitoflash activity in the SOD1G93A (G93A) mouse muscle showed an increased flashing frequency prior to the onset of ALS symptom (at the age of 2 months), whereas the onset of ALS symptoms (at the age of 4 months) is associated with drastic changes in the kinetics property of mitoflash signal with prolonged full duration at half maximum (FDHM). Elevated levels of cytosolic ROS in skeletal muscle derived from the SOD1G93A mice were confirmed with fluorescent probes, MitoSOX™ Red and ROS Brite™570. Immunoblotting analysis of subcellular mitochondrial fractionation of G93A muscle revealed an increased expression level of cyclophilin D (CypD), a regulatory component of the mitochondrial permeability transition pore (mPTP), at the age of 4 months but not at the age of 2 months. Transient overexpressing of SOD1G93A in skeletal muscle of wild type mice directly promoted mitochondrial ROS production with an enhanced mitoflash activity in the absence of motor neuron axonal withdrawal. Remarkably, the SOD1G93A-induced mitoflash activity was attenuated by the application of cyclosporine A (CsA), an inhibitor of CypD. Similar to the observation with the SOD1G93A transgenic mice, an increased expression level of CypD was also detected in skeletal muscle following transient overexpression of SOD1G93A. Overall, this study reveals a disease-stage-dependent change in mitochondrial function that is associated with CypD-dependent mPTP opening; and the ALS mutation SOD1G93A directly contributes to mitochondrial dysfunction in the absence of motor neuron axonal withdrawal.

Abstract
Neurofibromatosis Type 1 (NF1) is an autosomal dominant genetic disorder caused by NF1 gene mutations. Café au lait spots, neurofibromatosis, Lisch nodules, axillary freckling, dermal neurofibromas and skeletal dysplasia are the most common manifestations for this disease. A 11-year-old boy visited Third Xiangya Hospital, Central South University due to growth-retardation. He was eventually diagnosed as NF1 with growth hormone deficiency. A novel heterozygous splicing mutation c.6579+2 T>C (IVS 34+2 T>C) of NF1 gene was identified in the patient and his mother. Considering NF1 may present with short stature due to growth hormone deficiency, all children with short stature combined with café au lait spots should be screened for NF1, which may assist the clinical diagnosis and the genetic counseling.

Abstract
Chronic inflammation is a key contributor to obesity-related insulin resistance and type 2 diabetes (T2D). NLRP3 inflammasome activation plays an important role in impairing insulin signaling and insulin sensitivity. Adiponectin is an adipocyte-derived cytokine that has been shown to promote insulin sensitivity and exert anti-inflammatory properties, yet the detailed mechanism is still unclear. In this study, we aimed to investigate the anti-inflammatory effect of adiponectin on lipopolysaccharide (LPS) plus palmitic acid (PA)-induced THP-1 cells and to identify the underlying mechanism. We report here that adiponectin was able to inhibit interleukin (IL)-1β and IL-18 by suppressing NLRP3 inflammasome activation. Furthermore, we, for the first time, describe that adiponectin attenuates NLRP3 inflammasome activation by modulating the AMPK-ROS signaling pathway. These findings provide insight suggesting that adiponectin and NLRP3 inflammasome be considered molecular targets for the development of new treatment for T2D and the related metabolic diseases.

Abstract
Kallmann syndrome (KS) is a clinically and genetically heterogeneous disorder characterized by hypogonadotropic hypogonadism and olfactory dysfunction. Recently, mutations in SOX10, a well-known causative gene of Waardenburg syndrome (WS), have been identified in a few KS patients with additional developmental defects including hearing loss. However, the understanding of SOX10 mutation associates with KS and other clinical consequences remains fragmentary. A 30-year-old Chinese male patient presented with no pubertal sex development when he was at the age of twelve years. Additionally, he showed anosmia, sensory deafness, and blue irises. Last year, he developed clinical symptoms of hyperthyroidism with a fast heartbeat, heat intolerance and weight loss. Blood examinations revealed low levels of FSH, LH, and testosterone. Thyroid function showed high levels of FT3, FT4 and extremely low level of TSH. Molecular analysis detected a de novo (c.565G>T/p.E189X) mutation in SOX10, which has previously been reported in a patient with WS4 (WS with Hirschsprung). The mutation was predicted to be probably damaging. These results highlight the significance of SOX10 haploinsufficiency as a genetic cause of KS. Importantly, our result implies that the same SOX10 mutation can underlie both typical KS and WS, while the correlation between SOX10 and hyperthyroidism still needs to be clarified in the future.

Abstract
Two patients with primary hypertrophic osteoarthropathy (PHO) and their available healthy family members were studied. All exons of the SLCO2A1 and HPGD gene and adjacent exon-intron sequences were amplified by PCR and subsequently sequenced. To assess the damaging effects of missense mutations in silico, the online database, PolyPhen-2 and SIFT were used. We identified two homozygous mutations in SLCO2A1 gene: one was c.1106G>A (p.G369D) in exon 9, the other was c.611C>T (p.S204L) in exon 4. No HPGD mutation was found in the affected individuals. The two mutation were predicted in silico by the bioinformatic tools. Our study further supports the role of mutations in the SLCO2A1 gene in the pathogenesis of PHO. Identification of the genotype in PHO may not only help the clinical diagnosis of PHO but also help the interpretation of genetic information for prenatal diagnosis and genetic counseling.

Abstract
Multiple symmetric lipomatosis (MSL) is a rare disorder characterized by aberrant multiple and symmetric subcutaneous adipose tissue accumulation in the face, neck, shoulders, back, chest and abdomen, severely affecting the quality of life of patients. At present, precise MSL etiology and pathogenesis remain to be elucidated. The present study first utilized a digital gene expression technique with a next‑generation sequencing platform to profile differentially expressed genes in three cases of MSL vs. normal control tissue. cDNA libraries from these tissue specimens were constructed and DNA sequenced for identification of differentially expressed genes, which underwent bioinformatic analysis using the Gene Ontology (GO) enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) and protein‑protein interaction (PPI) network analyses. As a result, a total of 859 differentially expressed genes were identified, including 308 upregulated genes (C19orf80, Apelin, C21orf33, FAM166B and HSD11B2 were mostly upregulated 6.984‑, 4.670‑, 4.412‑, 3.693‑ and 3.561‑fold, respectively) and 551 downregulated genes [FosB proto‑oncogene, AP‑1 transcription factor subunit (FOSB), selectin (SEL) E, RAR related orphan receptor (ROR) B, salt inducible kinase (SIK)1 and epidermal growth factor‑like protein (EGFL)6 were mostly downregulated ‑9.845, ‑8.243, ‑8.123, ‑7.702 and ‑7.664 fold, respectively). The GO functional enrichment analysis demonstrated these differentially expressed genes were predominantly involved in biological processes and cellular components, while the KEGG pathway enrichment analysis demonstrated that ribosome, non‑alcoholic fatty liver disease, human T‑lymphotropic virus type 1 (HTLV‑I) infection and Alzheimer's disease pathways were altered in MSL. The PPI network data demonstrated ubiquitin C (UBC), translocator protein (TSPO), Jun Proto‑Oncogene, AP‑1 Transcription Factor (JUN) and FOS were among these differentially expressed genes that participated in regulation of adipocyte differentiation, although no previous study has linked them to MSL. In conclusion, the present study profiled differentially expressed genes in MSL and identified gene pathways that may be associated with MSL development and progression.

Abstract
Individuals with the human neutrophil antigen (HNA)-3b/3b type can produce HNA-3a antibodies, which have been reported to cause severe, sometimes fatal transfusion-related acute lung injury (TRALI). Our study aimed to determine the genotype frequency of HNA-3a/3b which will be helpful to estimate the potential risk for forming anti-HNA-3a, the clinically relevant antibody linked to TRALI in two different ethnic groups of southern China. Five hundred unrelated and healthy blood donors (284 male, 216 female; 300 Zhuangs, 200 Dongs) from the Guangxi Zhuang Autonomous Region were simultaneously typed for the HNA-3 allele using a polymerase chain reaction sequence-based typing (PCR-SBT) method. Genotype frequencies of HNA-3a/3a, HNA-3a/3b and HNA-3b/3b were 51.7%, 39.7% and 8.6% in the Zhuang population, and 44.0%, 49.0% and 7.0% in the Dong population, respectively. Homozygous HNA-3b/3b genotype frequency among the Zhuang population (8.6%) was significantly higher than previously reported in African Americans (0.4%), Brazilians (3.6%) and English Caucasians (2.9%) (p < .05). And the HNA-3b/3b genotype frequency among the Dong population was higher than African Americans (0.4%) (p < .05). This study showed Chinese Zhuang and Dong populations possessed a higher frequency of HNA-3b/3b genotype, suggesting that they may be at greater risk for developing anti-HNA-3a alloantibodies that may cause severe cases of TRALI. A molecular-based identification of the HNA-3b/3b genotype in all multiparous female blood donors was suggested to reduce the risk of TRALI following plasma and whole blood allogeneic transfusions.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is a significant burden in China, where approximately 114 million patients have been diagnosed with diabetes. Chinese patients present with prominent β-cell failure, with resulting deficiency in insulin secretion, particularly early phase insulin secretion leading to postprandial hyperglycemia. Sitagliptin, a selective once-daily oral dipeptidyl peptidase-4 inhibitor, has been shown to improve glycemic control as monotherapy and in combination with other antihyperglycemic agents, including sulfonylureas and metformin. METHODS This was a multicenter randomized double-blind placebo-controlled study conducted in China. The study assessed the safety and efficacy of the addition of sitagliptin 100 mg once daily versus placebo on changes from baseline at Week 24 in HbA1c, fasting plasma glucose (FPG) and 2-h post-meal glucose (PMG). Patients were aged 18-79 years, had T2DM with inadequate glycemic control, and were taking a sulfonylurea, with or without metformin. RESULTS After 24 weeks, sitagliptin reduced HbA1c, FPG, and 2-h PMG significantly more than placebo (between-treatment differences: -0.61 %, -16.8 mg/dL, and -32.9 mg/dL, respectively; P < 0.001 for all). The addition of sitagliptin was generally well tolerated, with a comparable incidence of adverse events and drug-related adverse events in both treatment groups. The sitagliptin group had a higher incidence of symptomatic hypoglycemia than the placebo group (25/248 [10.1 %] vs 13/249 [5.2 %], respectively; P = 0.042). CONCLUSIONS Sitagliptin 100 mg once daily significantly improved glycemic control in Chinese patients with T2DM who had inadequate glycemic control with sulfonylurea, with or without metformin therapy. The addition of sitagliptin was generally well tolerated. (clinicaltrials.gov: NCT01590771).

Abstract
Osteoporosis is one of the most common skeletal disease featured by osteopenia and adipose accumulation in bone tissue. NLRP3 inflammasome activation is an essential player in aging-related chronic diseases like osteoporosis, particularly due to the causal caspase-1 activation and its correlation to adipose accumulation in bone tissue. Moreover, the expression of anti-aging/senescence SIRT1 was reported to decline along with aging. As the major cellular contributor of bone formation, mesenchymal stem cells (MSCs) are multipotent stem cells processing mutually exclusive differentiatability toward osteocytes or adipocytes. Therefore, we hypothesized that NLRP3 inflammasome activation promotes adipogenesis and repress osteogenesis in MSCs via inhibiting SIRT1 expression. We activated NLRP3 inflammasome in human MSCs via lipopolysaccharide and palmitic acid (LPS/PA) treatment for self-renewal maintenance, adipogenic differentiation or osteogenic differentiation. LPS/PA treatment significantly increased NLRP3 expression, decreased SIRT1 expression and promoted caspase-1 activity in MSCs. LPS/PA treatment also boosted adipogenesis of MSCs and suppressed osteogenesis. Moreover, inhibition of caspase-1 activity repressed adipogenic differentiation and partially improved osteogenic differentiation of MSCs with LPS/PA treatment. Our study demonstrated the pivotal roles of NLRP3 inflammasome and downstream mediator caspase-1 for the progress of osteo-differentiation MSCs, and offered novel therapeutic target of treatment for osteoporosis.

Abstract
RATIONALE Hyperthyroidism is one of the major clinical causes of hypercalcaemia, however, hyperthyroidism-related hypercalcemic crisis is rare, only 1 case have been reported. The potential mechanisms are still not too clear. It may be related that thyroid hormone stimulate bone turnover, elevate serum calcium, increase urinary and fecal calcium excretion. PATIENT CONCERNS A 58-year-old female patient was found to have Graves' disease, a marked elevated serum calcium level (adjusted serum calcium: 3.74 mmol/L), and reduced parathyroid hormone level. DIAGNOSES She was diagnosed as hyperthyroidism-associated hypercalcemic crisis. INTERVENTIONS Treatment with methimazole to correct the hyperthyroidism and treatment of the patient's hypercalcaemia was achieved by physiological saline, salmon calcitonin and furosemide. OUTCOMES After treatment for hypercalcaemia and hyperthyroidism, her symptoms and serum calcium levels quickly returned to normal. LESSONS hyperthyroid-associated hypercalcaemia crisis is rare, however, the diagnosis should pay attention to screening for other diseases caused by hypercalcemia. Timely treatment of hypercalcaemia is a critical step for rapidly control of symptoms, and treatment of hyperthyroidism is beneficial to relief the symptoms and maintain the blood calcium level.

Abstract
Van Wyk-Grumbach syndrome (VWGS) is a rare complication of prolonged untreated juvenile hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. A 13-year-old girl visited our outpatient clinic due to menstrual irregularities. She had precocious puberty, pituitary hyperplasia and multiple cystic ovaries in addition to clinical signs of severe congenital hypothyroidism. After the initiation of L-thyroxine therapy, the symptoms were alleviated in a short time. This rare syndrome is easy to be misdiagnosed as pituitary and ovarian tumor. High degree of suspicion and timely diagnosis can prevent unnecessary surgical procedures because the symptoms can be reversed with thyroid hormone supplementation.

Abstract
The aim of this study was to describe the prevalence of and risk factors for prostatitis-like symptoms and its relation to erectile dysfunction (ED) among southern Chinese men. Data were collected from 2790 men attending the Fangchenggang Area Male Healthy and Examination Survey from September 2009 to December 2009. The prostatitis-like symptoms were assessed by the NIH Chronic Prostatitis Symptom Index and ED was assessed using the 5-item International Index of Erectile Function. Lifestyle and demographic characteristics were obtained through a questionnaire. Prevalence of prostatitis-like symptoms was 12.4% among 2790 Chinese men aged 20-84 years. In smokers who smoked ≥20 cigarettes per day (age-adjusted OR = 1.29; 95% CI = 1.00-1.66; p = 0.04), physical inactivity (age-adjusted OR = 1.31; 95% CI = 1.03-1.66; p = 0.02) was a significant risk factor for prostatitis-like symptoms. Alcohol consumption (daily drinking) also was a risk factor for prostatitis-like symptoms, although the differences were not statistically significant (age-adjusted OR = 1.36; 95% CI = 0.96-1.92; p = 0.07). Those with diabetes may also be at higher risk for prostatitis-like symptoms (age-adjusted OR = 1.37; 95% CI = 0.85-2.21; p = 0.19). In addition, men with ED were more likely to have had prostatitis-like symptoms (age-adjusted OR = 1.86; 95% CI = 0.47-2.36; p < 0.0001), and the ORs increased with increasing severity of ED status (mild ED, mild to moderate ED, and moderate to severe ED were 1.57, 2.62, and 3.24, respectively. Test for trend, p = 0.0001). Our results show that prostatitis-like symptoms are prevalent in Southern China affecting men of all ages. Smoking, drinking, lack of physical activity, and elevated plasma glucose level were associated with an increased risk of prostatitis-like symptoms. In addition, our results reveal that ED accounted for a large proportion (61.5%) among men with prostatitis-like symptoms; we also confirm the magnitude of ED associated with prostatitis-like symptoms. Thus, interventions to evaluate and improve ED might help ameliorate prostatitis-like symptoms and vice versa.

Abstract
Chronic inflammation has been associated with a variety of human cancers including prostate cancer. Interleukin-17 (IL-17) is a critical pro-inflammatory cytokine, which has been demonstrated to promote development of prostate cancer, colon cancer, skin cancer, breast cancer, lung cancer, and pancreas cancer. IL-17 promotes prostate adenocarcinoma with a concurrent increase of matrix metalloproteinase 7 (MMP7) expression in mouse prostate. Whether MMP7 mediates IL-17’s action and the underlying mechanisms remain unknown. We generated Mmp7 and Pten double knockout (Mmp7−/− in abbreviation) mouse model and demonstrated that MMP7 promotes prostate adenocarcinoma through induction of epithelial-to-mesenchymal transition (EMT) in Pten-null mice. MMP7 disrupted E-cadherin/β-catenin complex to up-regulate EMT transcription factors in mouse prostate tumors. IL-17 receptor C and Pten double knockout mice recapitulated the weak EMT characteristics observed in Mmp7−/− mice. IL-17 induced MMP7 and EMT in human prostate cancer LNCaP, C4-2B, and PC-3 cell lines, while siRNA knockdown of MMP7 inhibited IL-17-induced EMT. Compound III, a selective MMP7 inhibitor, decreased development of invasive prostate cancer in Pten single knockout mice. In human normal prostates and prostate tumors, IL-17 mRNA levels were positively correlated with MMP7 mRNA levels. These findings demonstrate that MMP7 mediates IL-17’s function in promoting prostate carcinogenesis through induction of EMT, indicating IL-17-MMP7-EMT axis as potential targets for developing new strategies in the prevention and treatment of prostate cancer.

Abstract
Chronic elevated glucose is harmful to pancreatic β-cells, resulting in pancreatic β-cells dysfunction and apoptosis. Understanding the molecular mechanisms associated with β-cells survival is pivotal for the prevention of β-cells injury caused by glucotoxicity. The role of Phosphatase and tensin homologue (PTEN)-induced putative kinase 1 (PINK1) in the fate of pancreatic β-cells constantly exposed to high glucose was studied. Sustained high glucose increased PINK1 protein expression both in rat pancreatic β-cells and INS-1 β-cells, and that this increase can be inhibited by PINK1 knockdown and further enhanced by PINK1 over-expression. PINK1 deficiency aggravated glucotoxicity-induced pancreatic β-cells apoptosis and inhibition of autophagy whereas PINK1 could reverse these adverse effects. This study provides fundamental data supporting the potential protective role of PINK1 as a new therapeutic target necessary to preserve β-cells survival under non-physiological hyperglycemia conditions.

Abstract
To determine the annual incidence and clinically relevant risk factors for foot ulceration in a large cohort study of diabetic foot ulcer (DFU) patients and diabetes mellitus (DM) patients in China. To investigate a cohort of 1,333 patients comprising 452 DFU patients and 881 DM patients, who underwent foot screening, physical examination, and laboratory tests in eight hospitals. The patients were assessed at baseline in terms of their demographic information, medical and social history, peripheral neuropathy disease (PND) screening, periphery artery disease (PAD) screening, assessment of nutritional status, and diabetic control. One year later, the patients were followed up to determine the incidence of new foot ulcers, amputation, and mortality. By univariate analysis, statistically significant differences were found in age, location, gender, living alone (yes/no), occupation, smoking, hypertension, PND, PAD, nephropathy, retinopathy, cataracts, duration of diabetes, Glycosylated hemoglobin A (HbA1c), fasting plasma glucose level, postprandial blood glucose level, insulin level, blood urea nitrogen, creatinine, cholesterol, triglyeride, high density lipoprotein (HDL), serum albumin, white blood cell, and body mass index. A binary logistic regression model was used to examine which of these risk factors were independent risk factors for foot ulceration. A total of 687 (51.5%) of the 1,333 patients were followed up for an average of 12 months; there were 458 DM patients and 229 DFU patients. A total of 46 patients died during the follow-up period; 13 were DM patients, and 33 were DFU patients. Of the 641 patients, 445 (69.4%) patients were DM patients, and 196 (30.6%) were DFU patients. At follow-up, 36/445 DM patients (8.1%), and 62/196 DFU patients (31.6%), developed new ulcers; 10/196 DFU patients underwent an amputation. The annual incidence of ulceration for DM patients and amputation for DFU patients were 8.1 and 5.1%, respectively. The annual mortality of the DM patients and DMF patients were 2.8 and 14.4%, respectively. A binary logistic regression model was used to examine which risk factors were independent risk factors for foot ulceration during the follow-up period, and the final results showed that nephropathy (odds ratio 2.32), insulin level (odds ratio 3.136, 2.629), and decreased HDL (odds ratio 0.427) were associated with increased risks for foot ulceration. Complications of diabetes affecting the feet represent a serious problem in China. The incidence of foot ulcers and amputation are much higher than that of Western countries. More intensive surveillance and aggressive care following a diagnosis of DFU and earlier referral to specialty care might improve the patient outcome.

Abstract
OBJECTIVE To explore the eff ect of silibinin on β cells in C57BL/6J mice fed a high-fat diet and the possible mechanisms. METHODS A total of 18 male C57BL/6J mice at 3 weeks old were divided into a normal chow group (n=6), a high-fat diet group (n=6) and a high-fat diet plus silibinin group (n=6). Aft er intervention for 10 weeks, fasting blood glucose (FBG), fasting insulin (FINS), triglycerides (TG), alanine aminotransferase (ALT), creatinine (Cr) and blood urea nitrogen (BUN), lipid metabolism, antioxidant enzyme activities and apoptosis were evaluated. Pancreatic tissues were isolated to examine insulin-induced gene-1 (Insig-1), sterol regulatory element binding protein-1c (SREBP-1c) and fatty acid synthetase (FAS) mRNA and protein expression. RESULTS Compared with the high-fat diet group, the function of insulin secretion was improved, and the level of blood glucose was decreased in the high-fat diet plus silibinin group (P<0.05). The levels of lipid content and oxidative stress and the rates of β cell apoptosis were lower in high-fat diet plus silibinin group than those in the high-fat diet group (both P<0.05). Simultaneously, the silibinin could promote the expression of Insig-1 and depress the expression of SREBP-1c and FAS (all P<0.05). Moreover, there was no significant difference in the levels of serum ALT, Cr and BUN among the 3 groups (all P>0.05). CONCLUSION Silibinin can protect β cells of mice fed a high-fat diet, and this effect might be related to, at least partially, increase in its antioxidative ability through regulation of insig-1/SREBP-1c pathway. Moreover, silibinin is safe for long-term treatment.

Abstract
Multiple symmetric lipomatosis (MSL) is a rare disease characterized by symmetric and abnormal distribution of subcutaneous adipose tissue (SAT); however, the etiology is largely unknown. We report here that miR-125a-3p and miR-483-5p are upregulated in the SAT of MSL patients, promoting adipogenesis through suppressing the RhoA/ROCK1/ERK1/2 pathway. TaqMan microRNA (miR) array analysis revealed that 18 miRs were upregulated in the SAT of MSL patients. Transfection of human adipose-derived mesenchymal stem cells (hADSCs) with the individual agomirs of these 18 miRs showed that miR-125a-3p and miR-483-5p significantly promoted adipogenesis. A dual-luciferase assay showed that RhoA and ERK1 were the targets of miR-125a-3p and miR-483-5p, respectively. Moreover, transfection of hADSCs with mimics of miR-125a-3p and miR-483-5p resulted in a pronounced decrease of ERK1/2 phosphorylation in the nucleus; conversely, transfection of hADSCs with inhibitors of miR-125a-3p and miR-483-5p led to a significant increase of ERK1/2 phosphorylation in the nucleus. Most importantly, we found that miR-125a-3p and miR-483-5p promoted de novo adipose tissue formation in nude mice. These results demonstrated that miR-125a-3p and miR-483-5p coordinately promoted adipogenesis through suppressing the RhoA/ROCK1/ERK1/2 pathway. Our findings may provide novel strategies for the management and treatment of MSL or obesity.

Abstract
Only a few previous studies have demonstrated an association between resistance to thyroid hormone (RTH) and thyroid cancer. The current study presents the case of a 67-year-old female who was referred to the Third Xiangya Hospital of Central South University with an enlargement of the neck that had grown gradually over two years and subsequently, rapidly enlarged over the two months prior to admission, alongside a slight sensation of shortness of breath. Laboratory data revealed a significantly increased level of thyroid-stimulating hormone (TSH), total triiodothyronine, total thyroxine, free triiodothyronine, free thyroxine, thyroprotein and thyroglobulin antibody; however, the levels of thyroperoxidase and TSH receptor antibody were within the normal ranges. A thyroid hormone suppression test revealed a TSH reduction of 32%, Magnetic resonance imaging of the pituitary gland was negative for abnormalities. The patient's thyroid pathology revealed a non-Hodgkin's lymphoma of the thyroid. CHOP + nimustine chemotherapy significantly reduced the clinical symptoms. The genetic analysis revealed a novel point mutation of the thyroid hormone receptor β (THRB) gene in exon 10 (g1680 G to A) in the 3'-untranslated region of the patient. To the best of our knowledge, this is the first case report of RTH with thyroid non-Hodgkin's lymphoma, which involved a mutation (g1680 G to A) in exon 10 of THRB.
