Abstract
Objective To investigate the impact of sarcopenia on the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) among individuals with type 2 diabetes mellitus (T2DM). Methods This study included the clinical, laboratory, and body composition data of 1491 patients with T2DM who were admitted to the Department of Endocrinology and Metabolism at Tianjin Union Medical Center from July 2018 to July 2023. The China-PAR model was utilized to evaluate cardiovascular disease risk. Associations between ASCVD risk and various clinical parameters were analyzed, and the relationship between body composition parameters and ASCVD risk was assessed using logistic regression. Results The analysis revealed that T2DM patients with sarcopenia had a higher 10-year ASCVD risk compared to those without sarcopenia, with reduced muscle mass independently predicting an increased risk of cardiovascular disease. This association was significant among female T2DM patients, while male T2DM patients with sarcopenia showed a marginally higher median ASCVD risk compared to their non-sarcopenic counterparts. ASCVD risk inversely correlated with body muscle parameters and positively correlated with fat content parameters. Specifically, height- and weight-adjusted fat mass (FM, FM%, FMI) were identified as risk factors for ASCVD. Conversely, muscle parameters adjusted for weight and fat (ASM%, SMM%, FFM%, ASM/FM, SMM/FM, FMM/FM) were protective against ASCVD risk. These findings highlight the critical role of sarcopenia in influencing cardiovascular disease risk among Chinese patients with T2DM, as predicted by the China-PAR model. Conclusion This study highlights the importance of sarcopenia in T2DM patients, not only as an indicator of ASCVD risk, but possibly as an independent risk factor in this demographics.

Abstract
To investigate the safety and feasibility of gasless total endoscopic resection of deep lobe parotid gland tumors via a postauricular hairline plus temporal approach. The approach was designed as: a 4 to 5 cm main incision was designed at the postauricular hairline, and a 0.5 cm auxiliary incision was designed in the temporal hairline. The operating cavity was established with the assistance of a special retractor. "Anterograde" dissection of the facial nerve was performed throughout the procedure, along with partial or total gland removal of the tumor. All 16 operations were successfully completed without conversion to open surgery. During the operation, the trunk and branches of the facial nerve were completely preserved, the tumor was completely removed, and the incision healed. Six patients had mild facial paralysis after operation, and recovered completely after 3 to 6 months. There was no salivary fistula, Frey syndrome, infection, or other complications. The postoperative incision was concealed and the aesthetic effect was good. The postauricular hairline plus temporal approach gasless total endoscopic parotidectomy is safe and feasible. This technique can achieve the complete dissection of the total trunk to the branches of the facial nerve, and has good access to the tumors located in any part of the parotid gland region. On the basis of radical resection of the tumor, it achieves minimally invasive and aesthetic improvement.

Abstract
BACKGROUND The purpose of the study was to compare the efficacy of two novel obesity indices, lipid accumulation product (LAP) and visceral adiposity index (VAI), with traditional obesity indices in predicting early-onset type 2 diabetes (T2DM). METHODS In this cross-sectional study, a total of 744 participants, including 605 patients newly diagnosed with T2DM and 139 non-diabetic control subjects, were enrolled from a tertiary care hospital in Tianjin, China. Participants with T2DM were divided into two groups based on their age at diagnosis, namely early-onset T2DM (age less than 40 years, n = 154) and late-onset T2DM (age 40 years or older, n = 451). The predictive power of each obesity index was evaluated using receiver operating characteristic (ROC) curve analysis. Furthermore, binary logistic regression analysis was conducted to examine the independent relationship between LAP and VAI with early-onset T2DM risk. The relationship between novel obesity indices and the age of T2DM onset was also evaluated through correlation and multiple linear regression analysis. RESULTS In males, LAP had the highest predictive power for early-onset T2DM with an area under the ROC curve (AUC) of 0.742 (95% CI 0.684-0.799, P < 0.001). In females, VAI had the highest AUC for early-onset T2DM with a value of 0.748 (95% CI 0.657-0.839, P < 0.001), which was superior to traditional indices. Patients in the 4th quartile of LAP and VAI had 2.257 (95% CI 1.116-4.563, P = 0.023) and 4.705 (95% CI 2.132-10.384, P < 0.001) times higher risk of T2DM before age 40, compared to those in the 1st quartile, respectively. A tenfold increase in LAP was associated with a decrease in T2DM onset age of 12.862 years in males (β = -12.862, P < 0.001) and 6.507 years in females (β = -6.507, P = 0.013). A similar decrease in T2DM onset age was observed for each tenfold increase in VAI in both male (β = -15.222, P < 0.001) and female (β = -12.511, P < 0.001) participants. CONCLUSIONS In young Chinese individuals, LAP and VAI are recommended over traditional obesity indices for improved prediction of early-onset T2DM risk.

Abstract
Medium-chain acyl-CoA dehydrogenase (MCAD) is one of the significant enzymes involved in the β-oxidation of mitochondrial fatty acids. MCAD deficiency affects the β-oxidation of fatty acid and leads to lipid deposition in multiple organs, but little is known about its importance in nonalcoholic steatohepatitis (NASH). Empagliflozin is revealed to effectively improve NASH by increasing research, whereas the specific mechanism still has to be explored. Human liver tissues of patients with or without NASH were obtained for proteomic analysis to screen proteins of interest. db/db mice were given empagliflozin by gavage for 8 weeks. The expression of MCAD and signaling molecules involved in hepatic lipid metabolism was evaluated in human liver, mice and HL7702 cells. We found that the MCAD levels in the liver were significantly reduced in NASH patients compared to patients without NASH. Protein-protein interaction network analysis showed that MCAD was highly correlated with forkhead box A2 (FOXA2) and protein kinase AMP-activated catalytic subunit alpha (PRKAA). AMPK/FOXA2/MCAD signaling pathway was detected to be inhibited in the liver of NASH patients. Decreased expression of MCAD was also observed in the livers of db/db mice and hepatocyte treated with palmitic acid and glucose. Of note, empagliflozin could upregulate MCAD expression by activating AMPK/FOXA2 signaling pathway, reduce lipid deposition and improve NASH in vivo and in vitro. This research demonstrated that MCAD is a key player of hepatic lipid deposition and its targeting partially corrects NASH. MCAD thus may be a potential therapeutic target for the treatment of NASH.

Abstract
BACKGROUND Visceral adiposity plays a key role in the development of insulin resistance (IR), so surrogate index that can indicate visceral obesity may have higher predictive value for IR. This study aimed to establish and validate a new predictive model including indicator of visceral obesity for IR. METHODS The study population consisted of two cohorts. The derivation cohort was a group of 667 patients with newly diagnosed type 2 diabetes and the population undergoing a routine health checkup was the validation cohort. The predictive model was established by the logistic regression analysis. Its value for predicting IR was compared with other surrogate indices by the receiver operating characteristic curve. RESULTS The odds ratio (OR) of age, visceral fat area (VFA), triglyceride (TG), fasting plasma glucose (FPG), and alanine aminotransferase (ALT) for IR was 1.028 (95% CI, 1.008-1.048) (P < 0.01), 1.016 (95% CI, 1.009-1.023) (P < 0.001), 1.184 (95% CI, 1.005-1.396) (P < 0.05), 1.334 (95% CI, 1.225-1.451) (P < 0.001), and 1.021 (95% CI, 1.001-1.040) (P < 0.05). The formula of the predictive model was (0.0293 × age + 1.4892 × Ln VFA + 0.4966 × Ln TG + 2.784 × Ln FPG + 0.6906 × Ln ALT)/2. The area under the curve was the largest among all the previously reported predictors. CONCLUSIONS This study established and validated a predicting model for IR and confirmed its predictive value in comparison with other surrogate indicators, which will offer a simple and effective tool to measure IR in future large population studies.

Abstract
INTRODUCTION Adipose tissue deposited on the viscera is the main culprit in the development of insulin resistance (IR) and cardiometabolic diseases, whereas subcutaneous adipose tissue may have a protective role. This study aimed to propose a new predictive index - the visceral-fat area (VFA)-to-hip-circumference ratio (VHR) and explore its efficacy for prediction of IR in a Chinese population with type 2 diabetes mellitus. METHODS A total of 643 patients with newly diagnosed diabetes were enrolled in this study. Body composition, anthropometrical, and biochemical measurements were performed. IR was defined as homeostatic model assessment of IR (HOMA-IR) > 2.69. The association between VHR and IR was analyzed. RESULTS Regardless of gender, subjects in the IR group had higher VHR, body mass index (BMI), VFA, body fat percentage, systolic blood pressure, diastolic blood pressure (DBP), fasting blood glucose, fasting insulin, triglyceride (TG), uric acid (UA), homocysteine, and aminotransferases than those in the non-IR group. The other concomitant metabolic disorders were more common in the IR group. Further analysis showed that with the increase of VHR, the levels of HOMA-IR, BMI, VFA, DBP, TG, UA and the prevalence of nonalcoholic fatty-liver disease, hypertension, and hyperuricemia increased continuously (p trend <0.01). The linear trend test showed that VHR and IR remained closely correlated after adjusting for possible confounders (p trend <0.05). The receiver operating characteristic curve analysis showed that the area under the curve was 0.69, and the optimal cutoff of VHR was 0.89 (sensitivity 79.3%, specificity 61.5%). CONCLUSION VHR was positively associated with IR regardless of gender, and it might be a reliable predictor for IR.

Abstract
Islet β cell dedifferentiation is one of the most important mechanisms in the occurrence and development of diabetes. We studied the possible effects of chemokine stromal cell-derived factor-1 (SDF-1) in the dedifferentiation of islet β cells. It was noted that the number of dedifferentiated islet β cells and the expression of SDF-1 in pancreatic tissues significantly increased with diabetes. In islet β cell experiments, inhibition of SDF-1 expression resulted in an increase in the number of dedifferentiated cells, while overexpression of SDF-1 resulted in a decrease. This seemed to be contradicted by the effect of diabetes on the expression of SDF-1 in pancreatic tissue, but it was concluded that this may be related to the loss of SDF-1 activity. SDF-1 binds to CXCR4 to form a complex, which activates and phosphorylates AKT, subsequently increases the expression of forkhead box O1 (FOXO1), and inhibits the dedifferentiation of islet β cells. This suggests that SDF-1 may be a novel target in the treatment of diabetes.

Abstract
Objective: To observe the efficacy and safety of S(+)-ketamine combined with sufentanil for patient-controlled intravenous analgesia (PCIA) in elderly patients undergoing laparoscopic radical resection of rectal cancer and explore its impact on patients' early recovery. Methods: One hundred and ten patients undergoing laparoscopic radical resection of rectal cancer in Affiliated Cancer Hospital of Zhengzhou University from December 2020 to March 2021, were divided into two groups (n=55) using a random number table: group S received PCIA, with continuous infusion of S(+)-ketamine combined with sufentanil, while group C received PCIA, with continuous infusion of sufentanil. PCIA was initiated at the end of the surgery, and the formulations were as follows: group S, S(+)-ketamine (1.44 mg/kg), sufentanil (1.05 μg/kg), ketorolac tromethamine (2.0 mg/kg) and tropisetron (5 mg), in 100 ml of normal saline; group C: sufentanil (1.50 μg/kg), ketorolac tromethamine (2.0 mg/kg) and tropisetron (5 mg), in 100 ml of normal saline. Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of remedial analgesia, the effective compressions number of PCI during 48 h after the operation. Time to first ambulation, time to first anal exhaust, time to resume oral feeding were recorded. The occurrence of adverse effects was compared between the two groups. Results: A total of 10 patients were excluded during the study, including 4 cases of conversion to laparotomy, 3 cases of dropping out of the study, and 3 cases with operation time more than 4 hours. Finally, 50 cases in group S and 50 cases in group C completed the study. There were no significant differences in VAS scores and Ramsay sedation sores at all time points between two groups (all P>0.05). Likewise, there were also no significant differences in the number of remedial analgesia and effective compressions of PCIA during 48 h after the operation between the two groups (both P>0.05). The total dosage of sufentanil consumption in group S [(64±9) μg] was lower than that in group C [(95±12) μg] within 48 h of PCIA, with a statistically significant difference (P<0.001). Time to first ambulation in group S was (1.1±0.2) d, which was shorter than that in group C [(1.6±0.5) d], and the difference was statistically significant (P<0.001). Likewise, time to first anal exhaust in group S [(1.3±0.4) d] was shorter than that in group C [(1.8±0.6) d], with a statistically significant difference (P<0.001). Additionally, time to resume oral feeding in group S was (2.5±0.6) d, which was shorter than that in group C [(3.1±0.7) d], and there was a statistically significant difference (P<0.001). The incidence of nausea, vomiting and pruritus in group S were 4.0%, 2.0% and 0, which were lower than that in group C (16.0%, 10% and 8.0%, respectively), with statistically significant differences (all P<0.05). No case with psychiatric symptoms was found in both groups. Conclusion: When used for postoperative intravenous analgesia in elderly patients undergoing laparoscopic radical resection of rectal cancer, S(+)-ketamine combined with sufentanil can provide satisfactory analgesic effects, decrease total consumption of sufentanil and the incidence of adverse effects, and thus facilitate patients' early recovery.

Abstract
Abstract
Study question
Does the presence of smooth endoplasmic reticulum clusters (sERCs) in oocytes affect the human embryo ploidy?
Summary answer
The euploidy rate of embryos originating from sERCs + oocytes is lower
What is known already
While an expert panel strongly recommended that sERCs+ oocytes should not be inseminated, some normal healthy babies derived from sERCs+ oocytes have been reported. In previous studies have shown that declined fertilization rate and lower proportions of good quality embryos are found in oocytes showing sERCs. The updating findings of the molecular status of sERC+ oocytes elucidated the sERCs+ oocytes may have impaired chromosomal segregation ability. However, no study reveals the relation between sERCs and embryo ploidy.
Study design, size, duration
A retrospective study enrolled 129 preimplantation genetic testing (PGT) cycles from January 2017 to March 2020 at Chang Gung Memorial Hospital, Lonkou.
Participants/materials, setting, methods
ICSI fertilization rate, Day5 usable blastocyst rate (D5UBR), total usable blastocyst rate (TUBR), euploidy rate, mosaic rate, and aneuploidy rate are investigated between embryo originating from sERCs+ and sERCs- oocytes.
Main results and the role of chance
Although higher TBUR in blastocyst derived from sERCs+ oocytes than sERCs- group (73.7% vs. 62.5%) but accompanied lower euploidy rate (7% vs. 29%) and higher aneuploid rate (79% vs. 54%).
Limitations, reasons for caution
Limited sample size, need a large-scale study to confirm the conclusion. The live-birth rate per embryo transfer cycle was not included for analysis. As we did not perform polar body analysis, we cannot state for sure that embryonic aneuploidy was related to the oocyte.
Wider implications of the findings: This study demonstrates that embryos originating from sERCs+ oocytes have a lower euploidy rate.

Abstract
PURPOSE Increasing evidences suggest dysfunctions of microRNAs (miRNAs) are playing important part in tumors. Therefore, the role of miR-802 in osteosarcoma (OS) was exploited. The object was to evaluate the effect of miR-802 and verify its influence on p27 Kip1 (p27) in OS. METHODS RT-qPCR experiment was used to detect miR-802 and p27 expression in OS tissues and cells. We explored the function of miR-802 through Transwell assays. The phosphoinositide 3-kinase (PI3K)/AKT serine/threonine kinase pathway and epithelial-mesenchymal transition (EMT) was detected by Western blot assays. Luciferase assay was used to testify the target of miR-802. RESULTS MiR-802 expression was elevated in OS, which was related to poor clinical outcome in OS patients. MiR-802 overexpression promoted OS migration, invasion and EMT. Further, p27 is a direct target of miR-802. P27 elevation counteracted the promotion effect of OS on EMT, migration and invasion induced by miR-802. In addition, miR-802 overexpression inactivated PI3K/AKT pathway via targeting p27 in OS. CONCLUSION MiR-802 promoted the progress of EMT, migration and invasion in OS via targeting p27. This newly identified miR-802/p27/PI3K/AKT axis may represent potential targets for OS.

Abstract
Objective: To investigate the effects of positive end-expiratory pressure (PEEP) setting of mechanical ventilation guided by esophageal pressure in the treatment of patients with traumatic craniocerebral injury combined with acute respiratory distress syndrome (ARDS). Methods: The retrospective cohort study was conducted. From June 2016 to June 2018, 55 patients with traumatic craniocerebral injury combined with ARDS who met the inclusion criteria were admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University. According to PEEP setting method, 28 patients were allocated to esophageal pressure group (17 males and 11 females, aged (40±13) years) and 27 patients were allocated to PEEP-fractional concentration of inspired oxygen (FiO2) table group (18 males and 9 females, aged (38±10) years). Patients in the 2 groups were treated with mechanical ventilation guided by lung protective ventilation strategy, and the optimal PEEP at 0 (immediately), 24, 48, and 72 h after treatment was determined according to esophageal pressure and PEEP-FiO2 table, respectively. The mechanical ventilation parameters in the 2 groups were adjusted according to the optimal PEEP. The transpulmonary end-expiratory pressure, pulmonary compliance, oxygen index, central venous pressure, mean arterial pressure, and intracranial pressure at 24, 48, and 72 h after treatment were recorded. Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, independent sample t test, and Bonferroni correction. Results: The optimal PEEP of patients in esophageal pressure group at 0, 24, 48, and 72 h after treatment was (12.4±3.9), (11.2±3.5), (13.4±2.6), and (13.2±3.6) cmH2O (1 cmH2O=0.098 kPa), respectively, which was significantly higher than (8.2±2.5), (7.4±2.2), (8.3±2.3), and (8.5±2.5) cmH2O in PEEP-FiO2 table group, respectively (t=4.702, 4.743, 7.849, 5.623, P<0.01). The transpulmonary end-expiratory pressure and pulmonary compliance at 24, 48, and 72 h after treatment and oxygen index at 48 and 72 h after treatment of patients in esophageal pressure group were significantly higher than those in PEEP-FiO2 table group (t=17.852, 20.586, 19.532, 4.752, 5.256, 7.446, 2.342, 4.178, P<0.05 or P<0.01). The central venous pressure of patients in esophageal pressure group at 24, 48, and 72 h after treatment was significantly higher than that in PEEP-FiO2 table group (t=12.632, 5.247, 8.994, P<0.01), and there was no statistically significant difference in mean arterial pressure of patients between the 2 groups at 24, 48, and 72 h after treatment (P>0.05). The intracranial pressure of patients in esophageal pressure group was higher than that in PEEP-FiO2 table group at 24, 48, and 72 h after treatment, but there was no statistically significant difference between the 2 groups (P>0.05). Conclusions: For patients with traumatic craniocerebral injury combined with ARDS, the optimal PEEP can be set under the guidance of esophageal pressure method, and the mechanical ventilation parameters adjusted according to the optimal PEEP can improve lung compliance and accelerate recovery of lung function more effectively, with no adverse effect in mean arterial pressure and intracranial pressure.

Abstract
Background Sexual transmission among men who have sex with men (MSM) is the dominant route of HIV transmission in China. Extensive use of geosocial networking (GSN) smartphone application (app) has dramatically changed the pattern of sexual behaviors and HIV risk among MSM, but data on HIV incidence and the changing risk behaviors of GSN app-using MSM are limited. We aims to assess the HIV incidence and its correlates among gay GSN app-using MSM in China. Methods We constructed an open cohort which was initiated and maintained using a GSN app to assess the HIV incidence among app-using MSM, recruited from June 2017 to December 2018. MSM completed an online questionnaire on their sociodemographic characteristics, sexual behaviors, recreational drug use and sexually transmitted infections status. Then each man had an HIV test, and those tested negatives were enrolled into the cohort. Participants completed follow-ups with additional HIV tests though the app during the study period, and were censored at HIV seroconversion or study end date. HIV incidence was calculated by dividing the sum of observed HIV seroconversions by the observed person-time. Univariate (Chi-square test and Fisher’s exact test) and multivariate (proportional hazards regression) analyses were used to examine correlates of HIV incidence. Results A total of 6957 HIV negative MSM were enrolled in the open cohort, 37 seroconversions occurred among 1937 men contributing 1065 observed person-years: HIV incidence was 3.47 per 100 person-years [95% confidence interval (CI): 2.37–4.57]. More than five sexual partners [hazard ratio (HR) = 2.65, 95% CI: 1.04–6.67], and sex with HIV positive partners (HR = 3.82, 95% CI: 1.16–12.64) in the preceding six months were positively associated with HIV seroconversion. Consistent condom use for anal sex (HR = 0.27, 95% CI: 0.07–0.96), and reporting insertive anal sex only (HR = 0.23, 95% CI: 0.08–0.62) in the preceding six months were protective factors for HIV seroconversion. Conclusions Tailored interventions targeting app-using MSM are urgently needed given their high risk of HIV. As a new tool for accessing MSM at higher HIV risk, GSN smartphone app could play an important role in HIV research among MSM. ![]()

Abstract
OBJECTIVE Obesity and sarcopenia are known to be closely related to nonalcoholic fatty liver disease (NAFLD). We attempted to explore the combined influence of fat and muscle tissue on NAFLD by using visceral fat area to appendicular muscle mass ratio (VAR) as a novel parameter. MATERIAL AND METHODS In this cross-sectional study, a total of 3255 adults (1399 men and 1856 women) coming for a health examination were enrolled. NAFLD was diagnosed using ultrasound and VAR was measured by bioelectrical impedance analyzer. RESULTS The prevalence of NAFLD was 46.5% in men and 26.6% in women. VAR differed significantly between subjects with and without NAFLD (4.27 vs. 3.26 in men, 7.89 vs. 5.01 in women, respectively, p < .001). Logistic regression analysis determined VAR as a risk factor for NAFLD, and the multivariable-adjusted odds ratios in the highest VAR quartile was 9.57 (95%CI: 5.98-15.30) for men and 12.37 (95%CI: 6.37-24.05) for women. From the receiver operating characteristic analysis, the area under the curve was 0.767 and 0.834, with the suitable cut-off VAR value of 3.469 and 6.357 for men and women, respectively. To control the influence of obesity, all subjects were stratified according to their BMI. For each BMI group, individuals with VAR above the cut-off value had significant higher prevalence and risk of NAFLD, with odds ratios ranging from 1.76 to 4.75. CONCLUSIONS Increased VAR is strongly associated with higher risk of NAFLD in both sexes independent of obesity and can serve as a screening reference for NAFLD.

Abstract
Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Abstract
BACKGROUND A significant positive association was found in previous studies among obesity, visceral fat accumulation, and hyperuricemia. The purpose of this study was to explore the association between the ratio of visceral fat area to leg muscle mass (VFA-to-LMM) and hyperuricemia, and verify the role of gender differences in the association. METHODS A total of 3393 (43.3% are men) participants from Tianjin Union Medical Center-Health Management Center were recruited for this cross-sectional study. The VFA-to-LMM ratio was used as the independent variable. Hyperuricemia, a serum uric acid level ≥ 416 μmol/L in men and in menopausal women and ≥ 357 μmol/L in premenopausal women, was used as the dependent variable. Multiple logistic regression analysis was used to estimate the odds ratio and the 95% confidence interval between the VFA-to-LMM ratio and hyperuricemia. RESULTS The overall prevalence of hyperuricemia was 14.8% (8.9% in women, and 22.5% in men). After adjustment by age, smoking status (for males), menopause status (for females), drinking status, exercise frequency, blood pressure, alanine aminotransferase, fasting plasma glucose, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, creatinine, and history of diseases, a strong positive association was found between the VFA-to-LMM ratio and hyperuricemia in both men (4th vs. 1st quartile 1.60, 95%CI: 1.03-2.49) and women (4th vs. 1st quartile 5.22, 95%CI: 2.44-12.56). After additional adjustment by BMI, there was still a significant positive association in women (4th vs. 1st quartile 2.57, 95%CI: 1.06-6.77). The results of subgroup analysis showed that pre-menopausal women (4th vs. 1st quartile OR: 3.61) have a higher risk of hyperuricemia than postmenopausal women (4th vs. 1st quartile OR: 1.94) with the increase of the VFA-to-LMM ratio. Besides, the interaction analysis results showed the highest risk of hyperuricemia when VFA and LMM were both in the highest quantile (OR: 11.50; 95% CI: 4.86-31.98). CONCLUSION The VFA-to-LMM ratio was positively associated with the risk of hyperuricemia in women after adjustment by confounders. Pre-menopausal women have a higher risk of hyperuricemia than postmenopausal women with the increase of the VFA-to-LMM ratio. In addition, the highest risk of hyperuricemia was demonstrated when both VFA and LMM were at the highest quartile.

Abstract
This study was conducted to determine the effect of feeding frequency on growth performance, carcass traits, and apparent nutrient digestibility in geese from 28 to 70 D of age. In experiment 1, a total of 240 geese were distributed in a completely randomized design into 4 treatments and 6 replicates of 10 birds each. The treatments were free access to the feeder (ad libitum) and access to the feeder 3, 4, and 5 times daily. Geese fed 3 times daily had a lower (P < 0.05) BW, ADG, and ADFI and a higher (P = 0.064) feed conversion ratio (FCR) from 28 to 41 D of age compared with the other groups. Geese fed 4 times daily had a higher (P < 0.05) ADG and ADFI and a lower (P < 0.05) FCR from 42 to 55 D of age compared with ad libitum fed geese. Geese fed 3 times daily had a higher (P < 0.05) ADG from 56 to 69 D of age than geese fed ad libitum and 4 times daily. No differences (P > 0.05) in BW, ADFI, ADG, and FCR were observed between ad libitum and feeding frequency groups from 28 to 69 D of age. Carcass traits and gastrointestinal development were not affected (P > 0.05) by feeding frequency. In experiment 2, the apparent nutrient digestibility in geese from 71 to 77 D of age fed using different feeding frequencies was determined using the total fecal collection method. Feeding frequency did not affect (P > 0.05) the apparent digestibility of DM, CP, crude ash, calcium, phosphorous, or ether extract in geese. Our study demonstrates for the first time that compensatory growth can be gained by enhancing feed intake when a lower feeding frequency is imposed on geese. Both ad libitum feeding and fixed feeding frequency for 3 to 5 times daily are suitable for geese from 28 to 70 D of age to achieve optimum production.

Abstract
Abstract
Background
With the outbreak of pandemics such as SARS, MERS and COVID-19 etc., making full use of artificial intelligence (AI) become the focus of social discussion. Some experts think AI can reduce infection probability of medical staffs and improve medical efficiency, while opponents believe AI will increase unemployment and medical ethical crises. We try to answer the question: From public perspective, could AI replace human doctors?
Methods
According to occupational status and biological gender, we select four groups as respondents: on-job and retired men, on-job and retired women. We investigate their attitudes towards AI application in medical field. After collecting 400 anonymous questionnaires, we use sample statistics, ANOVA and cluster method (CFSFDP) to find out cognitive similarities and differences between different groups.
Results
Reliability (Cronbach's alpha coefficient) and validity (KMO test) of questionnaires are 0.740 and 0.875 respectively. To the four groups, there are significant (p < 0.01) differences in answers of 7 questions but non-significant differences in the remaining 3 questions. By CFSFDP, questionnaires are automatically grouped into two clusters. Largest group in two clusters are on-job women and on-job men, respectively. Although 82.5% of respondents pay attention to news about AI, the overall average score for “public attitude to AI application in medical field” is 2.828 (full-score is 5.000), below neutral-score (3.000).
Conclusions
To AI application in medical field, cognitive differences among different groups are in existence, especially between on-job men and women. But in general, the public held a negative attitude towards the AI application in medical field, and trust human doctors more.
Key messages
According to the survey, it seems that AI is lesser probability to replace human doctors in recent years. It is also necessary to consider the public attitudes when promoting medical AI.

Abstract
Chemokine (C-X-C motif) receptor 7 (CXCR7), recently termed ACKR3, belongs to the G protein-coupled cell surface receptor family, binds to stromal cell-derived factor-1 [SDF-1, or chemokine (C-X-C motif) ligand 12] or chemokine (C-X-C motif) ligand 11, and is the most common chemokine receptor expressed in a variety of cancer cells. SDF-1 binds to its receptor chemokine (C-X-C motif) receptor 4 (CXCR4) and regulates cell proliferation, survival, angiogenesis and migration. In recent years, another new receptor for SDF-1, CXCR7, has been discovered, and CXCR7 has also been found to be expressed in a variety of tumor cells and tumor-related vascular endothelial cells. Many studies have shown that CXCR7 can promote the growth and metastasis of a variety of malignant tumor cells. Unlike CXCR4, CXCR7 exhibits a slight modification in the DRYLAIV motif and does not induce intracellular Ca2+ release following ligand binding, which is essential for recruiting and activating G proteins. CXCR7 is generally thought to work in three ways: (1) Recruiting β-arrestin 2; (2) Heterodimerizing with CXCR4; and (3) Acting as a “scavenger” of SDF-1, thus lowering the level of SDF-1 to weaken the activity of CXCR4. In the present review, the expression and role of CXCR7, as well as its prognosis in cancers of the digestive system, were investigated.

Abstract
Extracellular vesicles (EVs) including exosomes, microvesicles (MVs), and apoptotic bodies, are small membrane vesicular structures that are released during cell activation, senescence, or programmed cell death, including apoptosis, necroptosis, and pyroptosis. EVs serve as novel mediators for long-distance cell-to-cell communications and can transfer various bioactive molecules, such as encapsulated cytokines and genetic information from their parental cells to distant target cells. In the context of obesity, adipocyte-derived EVs are implicated in metabolic homeostasis serving as novel adipokines. In particular, EVs released from brown adipose tissue or adipose-derived stem cells may help control the remolding of white adipose tissue towards browning and maintaining metabolic homeostasis. Interestingly, EVs may even serve as mediators for the transmission of metabolic dysfunction across generations. Also, EVs have been recognized as novel modulators in various metabolic disorders, including insulin resistance, diabetes mellitus, and non-alcoholic fatty liver disease. In this review, we summarize the latest progress from basic and translational studies regarding the novel effects of EVs on metabolic diseases. We also discuss EV-mediated cross-talk between adipose tissue and other organs/tissues that are relevant to obesity and metabolic diseases, as well as the relevant mechanisms, providing insight into the development of new therapeutic strategies in obesity and metabolic diseases.

Abstract
Background: Chronic non-communicable diseases are the major causes of mortality in the world. However, few studies have investigated the association between multi-categories BMI and chronic diseases from perspective of sex stratification. This study aimed to investigate the risk of chronic diseases at different BMI levels, and to further explore whether BMI-health risk associations differ by sex. Methods: In total, 21,134 participants aged 19-65 years (60.4% men) from the Tianjin People's Hospital, Tianjin Union Medical Center-Health Management Center were recruited for this cross-sectional study. Sex-specific percentiles of BMI were calculated and divided into 11 categories according to the 2000 CDC growth charts. Health-related indicators, such as hyperglycemia, hypertension, non-alcoholic fatty liver diseases (NAFLD), hyperuricemia, etc., were used as dependent variables in this study. Statistical differences were tested by unpaired Mann-Whitney U-test and chi-squared test. Logistic regression models were used to examine the associations between BMI and health-related indicators. Results: The risk of hyperglycemia (OR: 1.67, 95%CI: 1.23-2.29), NAFLD (OR: 2.22, 95%CI: 1.74-2.85), hypertriglyceridemia (OR: 1.65, 95%CI: 1.28-2.12), and hyperuricemia (OR: 1.39, 95%CI: 1.12-1.72) in men began to increase significantly when BMI was in the range of 22.59-23.89 kg/m2. However, in women, the risk of hyperglycemia (OR: 3.02, 95%CI: 1.25-8.98) and hyperuricemia (OR: 1.94, 95%CI: 1.26-3.05) began to increase significantly when BMI was in the range of 22.76-23.62 kg/m2, and the risk of NAFLD (OR: 5.48, 95%CI: 2.49-14.47) began to increase significantly when BMI was in the range of 21.08-21.97 kg/m2. Besides, at the same BMI level, the risk of diseases in women were significantly higher than that in men, especially when BMI > 25 kg/m2. Conclusion: In the Chinese population, the risk of chronic diseases in women were significantly higher than that in men at the same BMI level, especially when BMI was >25 kg/m2. In addition, the risk of chronic diseases began to increase significantly when BMI was >21.97 kg/m2 in women and 23.89 kg/m2 in men. The results indicated that women should be more alert to the risk of chronic diseases caused by the increase of BMI than men.

Abstract
Hyperuricemia (HUA) is a metabolic disease characterized by elevated serum uric acid (SUA). Empagliflozin, a kind of sodium-glucose cotransporter 2 inhibitors, has recently emerged as a new antidiabetic agent by facilitating glucose excretion in urine. Moreover, there was evidence of SUA reduction following treatment with empagliflozin in addition to glycaemic control, while the molecular mechanisms remain unknown. To investigate the potential mechanisms, the model of type 2 diabetes (T2DM) with HUA was established by combination of peritoneal injection of potassium oxonate and intragastric administration of hypoxanthine in KK-Ay mice. A series of method such as RT-PCR, western blot, immunochemistry, immunofluorescence were conducted to explore the mechanism. Our results showed that empagliflozin significantly ameliorated the levels of SUA and blood glucose in T2DM mice with HUA. Furthermore, in both kidney and ileum, empagliflozin obviously promoted protein expression of uric acid (UA) transporter ABCG2, p-AMPK, p-AKT and p-CREB. The same trend was observed in human tubular epithelial (HK-2) cells. Additionally, through application of an AMPK inhibitor (Compound C), it was further confirmed empagliflozin exerted its anti-hyperuricemic effects in an AMPK dependent manner. Meanwhile, with the help of ChIP assay and luciferase reporter gene assay, we found that CREB further activated ABCG2 via binding to the promoter of ABCG2 to induce transcription. Taken together, our study demonstrated that empagliflozin treatment played an essential role in attenuating HUA by upregulation of ABCG2 via AMPK/AKT/CREB signaling pathway.

Abstract
Objective: Calcium dobesilate (CaD), an effective drug for the treatment of diabetic microvascular complications, especially diabetic retinopathy, is widely used in the clinic. Interestingly, several studies have indicated that CaD is therapeutic for diabetic kidney disease (DKD). Recently, evidence has indicated that altered vascular endothelial growth factor (VEGF) expression and decreased autophagy are the main pathological mechanisms of proteinuria. Thus, this study was conducted to explore the effect of CaD on restoring autophagy in DKD and the possible signaling pathway between VEGF and autophagy. Methods: Obese mice with spontaneous diabetes (KK-Ay) and high-fat diet- and streptozotocin-induced diabetic mice (HFD/STZ) were used in this study. Biochemical staining, western blotting, and immunohistochemistry were conducted to determine the angioprotective effect of CaD and the underlying mechanism between autophagy and VEGF/VEGFR. Results: Our results showed that CaD was capable of reducing albuminuria and restoring renal histological changes in KK-Ay and HFD/STZ-induced diabetic mice. CaD restored autophagy by decreasing the protein expression of LC3 II, Atg5, and beclin 1 and increasing the expression of P62. Moreover, CaD reduced the activation of the autophagy-related PI3K/AKT/mTOR pathway possibly via decreasing VEGF and downregulating VEGF receptor 2. Conclusion: Overall, CaD, as a novel potential therapeutic drug for DKD, plays a key role in protecting renal function and restoring autophagy by blocking VEGF/VEGFR2 and inhibiting the PI3K/AKT/mTOR signaling pathway.

Abstract
AIM Glucagon-like peptide-1 receptor agonists (GLP-1Ras) have been reported to prevent non-alcoholic fatty liver disease (NAFLD), but the potential mechanisms are still debated. MicroRNAs (miRNAs) play a prominent role in the field of metabolic disorders, including NAFLD. Our study was designed to further evaluate the effect of GLP-1Ra liraglutide on NAFLD in terms of miRNAs. METHODS MicroRNA expression was evaluated by clustering analysis of microRNA arrays in high fat diet-fed mice. The luciferase reporter assay was carried out to validate the cross-talk between adipose triglyceride lipase (ATGL) and miR-124a. MicroRNA-124a mimics and inhibitor plasmids were transfected to study the role of miR-124a in palmitate-treated normal human liver cell line (HL-7702). Liraglutide treatment was used to observe the effect of GLP-1Ra on the miR-124a/ATGL pathway. RESULTS Expression of ATGL decreased and miR-124a expression increased in hepatosteatosis in vivo and in vitro. Mechanistically, miR-124a interacted with the 3'-untranslated region of ATGL mRNA and induced its degradation. MicroRNA-124a overexpression antagonized the effect of liraglutide on NAFLD by inhibiting ATGL expression, whereas miR-124a knockdown led to elevated ATGL and sirtuin 1 (Sirt1) expression, and subsequently decreased lipid accumulation and inflammation in cells. CONCLUSIONS MicroRNA-124a overexpression contributes to the progression of NAFLD through reduction of ATGL expression, whereas miR-124a knockdown can reverse this trend, suggesting that miR-124a and its downstream target ATGL can be novel therapeutic targets of NAFLD. We reveal a novel mechanism by which liraglutide attenuates NAFLD by the miR-124a/ATGL/Sirt1 pathway.

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

Abstract
Objective: To analyze the influence of simulation mouse use motion under different wrist forcing postures on median nerve, tendons and ligaments in the carpal tunnel. Methods: From June to November in 2017, a total of 49 healthy volunteers [aged from 18 to 27 years, 24 males (48 cases of hands) and 25 females (50 cases of hands)] were selected in the Institute of Digitized Medicine and First Affiliated Hospital of Wenzhou Medical University.Three hand postures of the volunteers were simultaneously and continuously measured by using LOGIQ E9 ultrasonic diagnostic apparatus and Zebris foot pressure distribution measurement system.Seventeen parameters of nerves, tendons and ligaments in carpal tunnel were observed under natural (0 N), and two forced (25 and 50 N) states.Double factor variance analysis was performed with generalized estimating equation (GEE). Results: With increasing pressure (0, 25 and 50 N) of hand postures, the distance between median nerve and transverse carpal ligament were all less than 0.2 cm.The differences in both the distance between median nerve and flexor pollicis longus under the hand pressure changes or under the hand posture changes and the top angle of a triangle composed of median nerve, flexor pollicis longus and flexor digitorum superficialis group under the hand pressure changes or under the hand posture changes were all significant under the GEE analysis (all P<0.01). There were no significant changes in all other structural parameters in the carpal tunnel with the increasing of hand pressure (all P>0.05). Conclusions: The influence of the transverse carpal ligament to the median nerve belongs to the mechanism of pressure-induced irritation damage.The influence of flexor pollicis longus to median nerve belongs to the mechanism of tension-induced irritation damage.The influence of flexor digitorum superficialis to median nerve belongs to the mechanism of mixed shear irritation damage.

Abstract
Background: Imatinib has been regarded as the first successful synthetic small molecule targeting at blocking tyrosine kinase. Its high efficacy stabilized disease in above 80% of chronic myeloid leukemia (CML) patients over 10 years survival. Due to the similar canceration of gastrointestinal stromal tumor (GIST) as to CML, imatinib has been approved to be used as first-line treatment. Study design: Our retrospective study was proposed to enroll 191 GIST patients with larger tumor size (≥8 cm) who preoperative accepted imatinib from those with direct operation. Analysis included demographics, cancer specific survival and relationship of their risk factors. Results: Male patients and gastrointestinal (GI) tract location took higher proportion in total cases, detection of KIT mutant took 89.7% among all traceable genetic testing. Patients with preoperative imatinib can achieve higher cancer specific survival (CSS) after both in 1 year and 3 years duration than their counterpart. Tumor size above its threshold of 8 cm would be a hazardous factor for poor prognosis. Conclusion: In conclusion, as for regressing tumor progression and creating operative chance, preoperative imatinib should be considered for the patients with high risk, although the precise duration of this intervention needs further validation.

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

Abstract
Electrolyte gating is a powerful means for tuning the carrier density and exploring the resultant modulation of novel properties on solid surfaces. However, the mechanism, especially its effect on the oxygen migration and electrostatic charging at the oxide heterostructures, is still unclear. Here we explore the electrolyte gating on oxygen-deficient interfaces between SrTiO_{3} (STO) crystals and LaAlO_{3} (LAO) overlayer through the measurements of electrical transport, x-ray absorption spectroscopy, and photoluminescence spectra. We found that oxygen vacancies (O_{vac}) were filled selectively and irreversibly after gating due to oxygen electromigration at the amorphous LAO/STO interface, resulting in a reconstruction of its interfacial band structure. Because of the filling of O_{vac}, the amorphous interface also showed an enhanced electron mobility and quantum oscillation of the conductance. Further, the filling effect could be controlled by the degree of the crystallinity of the LAO overlayer by varying the growth temperatures. Our results reveal the different effects induced by electrolyte gating, providing further clues to understand the mechanism of electrolyte gating on buried interfaces and also opening a new avenue for constructing high-mobility oxide interfaces.

Abstract
Toll-like receptor 4 (TLR4)-mediated immune and inflammatory signaling serves a pivotal role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Our previous study demonstrated that celastrol treatment was able to improve hepatic steatosis and inhibit the TLR4 signaling cascade pathway in type 2 diabetic rats. The present study aimed to investigate the effects of celastrol on triglyceride accumulation and inflammation in steatotic HepG2 cells, and the possible mechanisms responsible for the regulation of cellular responses following TLR4 gene knockdown by small interfering RNA (siRNA) in vitro. A cell model of hepatic steatosis was prepared by exposing the HepG2 cells to free fatty acid (FFA) in the absence or presence of celastrol. Intracellular triglycerides were visualized by Oil red O staining, and the TLR4/myeloid differentiation primary response 88 (MyD88)/nuclear factor-κB (NF-κB) signaling cascade pathway were investigated. To directly elucidate whether TLR4 was the blocking target of celastrol upon FFA exposure, the cellular response to inflammation was determined upon transfection with TLR4 siRNA. The results revealed that celastrol significantly reduced triglyceride accumulation in the steatotic HepG2 cells, and downregulated the expression levels of TLR4, MyD88 and phospho-NF-κBp65, as well as of the downstream inflammatory cytokines interleukin-1β and tumor necrosis factor α. Knockdown of TLR4 also alleviated FFA-induced inflammatory response. In addition, co-treatment with TLR4 siRNA and celastrol further attenuated the expression of inflammatory mediators. These results suggest that celastrol exerts its protective effect partly via inhibiting the TLR4-mediated immune and inflammatory response in steatotic HepG2 cells.

Abstract
BACKGROUND AND STUDY AIMS To investigate the relationship among fibrotic, haemostatic and endotoxic changes in patients with different degrees of liver cirrhosis. PATIENTS AND METHODS Liver fibrotic markers, including hyaluronic acid (HA), Ccollagen IV (Col-IV), laminin (LN), and N-terminal pro-peptide of collagen type III (PIIINP), were determined by radioimmunoassay. A series of haemostatic tests, including prothrombin time (PT), international normalized ratio, activated partial thromboplastin time, antithrombin-III, thrombin time, fibrinogen, fibrin(ogen) degradation product and D-dimer were determined using an automatic coagulation analyszer. Plasma levels of endotoxin were detected quantitatively using an endotoxin detection kit. Correlation analysis of the data was performed. RESULTS Based on Child-Pugh classification, statistically significant differences in fibrotic markers and haemostatic parameters were found in 249 patients with liver cirrhosis, while no significant differences in endotoxin levels were observed. Based on ascites classification, statistically significant differences in fibrotic markers (such as HA, Col-IV and PIIINP, except for LN) and haemostatic parameters were found. As for endotoxin levels, there were significant differences between the ascites, spontaneous bacterial peritonitis (SBP) and no-ascites groups, while no significant differences were observed between the ascites and SBP groups. Correlation analysis demonstrated some correlation among fibrotic markers, haemostatic parameters and endotoxin. CONCLUSIONS A close relationship exists between the severity of cirrhosis and fibrotic changes, as well as haemostatic changes. Endotoxin may be an important contributing factor to the development of ascites in cirrhosis. Some correlation may exist between fibrosis, haemostatic and endotoxin.

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

Abstract
Complex-oxide materials exhibit physical properties that involve the interplay of charge and spin degrees of freedom. However, an ambipolar oxide that is able to exhibit both electron-doped and hole-doped ferromagnetism in the same material has proved elusive. Here we report ambipolar ferromagnetism in LaMnO3, with electron-hole asymmetry of the ferromagnetic order. Starting from an undoped atomically thin LaMnO3 film, we electrostatically dope the material with electrons or holes according to the polarity of a voltage applied across an ionic liquid gate. Magnetotransport characterization reveals that an increase of either electron-doping or hole-doping induced ferromagnetic order in this antiferromagnetic compound, and leads to an insulator-to-metal transition with colossal magnetoresistance showing electron-hole asymmetry. These findings are supported by density functional theory calculations, showing that strengthening of the inter-plane ferromagnetic exchange interaction is the origin of the ambipolar ferromagnetism. The result raises the prospect of exploiting ambipolar magnetic functionality in strongly correlated electron systems.

Abstract
OBJECTIVE To investigate the incidence of peri-anesthesia allergy in a tertiary teaching hospital. METHODS This was a retrospective cohort study. Patients who received anesthesia in operation rooms at Peking University First Hospital from January 2012 to April 2017 were enrolled. Researchers reviewed all the patients' electronic records and screened suspect allergy cases. Allergy was diagnosed according to the definition in Consensus on Management of Perioperative Allergy (China) and Scandinavian Clinical Practice Guidelines on the Diagnosis, Management and Follow-up of Anaphylaxis during Anesthesia. After obtaining the electronic records, two researchers began to screen and supplement missing data according medical records independently, then they checked out each other's data. The final data were reviewed by another two researchers. We collected the patients' basic characteristics, surgery type, anesthesia type, peri-anesthesia use of drugs, prognosis and other data. Univariate logistic regression was employed to screen potential factors of allergy. Factors with statistical significance (P<0.05) in univariate Logistic regression were entered into multivariate Logistic regression to identify independent risk factors of allergy. RESULTS In the study, 106 074 patients entered final statistic analysis. The incidence of peri-anesthesia allergy was about 1.5/1 000 (156/106 074). The incidence of Grades I, II and III allergy was 64.1% (100/156), 30.1% (47/156), and 5.8% (9/156) respectively. Multivariate logistic regression showed 5 independent risk factors of allergy including history of allergy (OR=6.836, 95%CI: 4.461-10.474, P<0.001), intraoperative use of sufentanil (OR=1.993, 95%CI: 1.228-3.232, P=0.005), intraoperative use of cis-atracuronium (OR=2.495, 95%CI: 1.599-3.893, P<0.001), intraoperative infusion of antibiotics (OR=2.005, 95%CI: 1.375-2.924, P<0.001) and frozen fresh plasma (OR=3.055, 95%CI: 1.842-5.068, P<0.001). CONCLUSION The incidence of peri-anesthesia allergy is high and further attempt is needed to establish standard operation process of diagnosis and treatment of allergy.

Acute right ventricular failure following extensive inferior wall myocardial infarction and complete atrioventricular block were noted and emergent angiography revealed insignificant coronary arterial stenosis. In view of the finding and absence of myocardial vasculitis, coronary artery spasm was implicated as the cause of myocardial infarction and complete atrioventricular block. After the reversal of the shock and successful angioplasty, the patient continued to take lercanidipine and had been angina-free during follow-up of 5 months. (Hong Kong j.emerg.med. 2013;20:396-399)

Abstract
Introduction We assessed whether a strategy using dynamic, internet-mediated, team-based case management could reduce the number of subsequent emergency department (ED) visits by frequent ED users. Methods Patients who attended the ED three or more times within 72 hours in June 2010 were identified. These cases were divided into the pain management or chronic disease group according to their chief complaint. Patients were assessed by expert panels, and initial care plans were developed and posted on an internal website. Thereafter, each emergency physician could follow or adjust the care plans dynamically via the internal website according to the patient's condition and use the website to communicate results. Care plans were revised by the team according to the patient's clinical situation as it changed. Patient ED visits over the subsequent six months were monitored. Results Fourteen cases were enrolled in the study, seven in each group. The mean number of visits per patient per month in the pain management and chronic disease groups decreased from 14.9 to 5.79 (p=0.031) and 6.1 to 2.9 (p<0.001) visits per month after the intervention, respectively. The overall mean number of visits per patient per month decreased from 10.5 to 4.36 (p=0.004), a decrease of 6.14 visits (58.27%). Conclusions Dynamic internet-mediated team-based case management may help to reduce subsequent visits in patients who frequently visit the ED. (Hong Kong j.emerg.med. 2014;21:161-166)

Abstract
Objective: To compare the long term safety and efficacy of the novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent(Firehawk stent) and permanent polymer coating everolimus eluting stent(Xience V stent) for the treatment of coronary de novo lesions. Methods: This prospective, multi-center, non-inferiority, randomized control trial(TARGETⅠ trial) was performed between August 2010 and April 2011, a total of 460 patients with primary, de novo, single vessel and single coronary lesion from 16 medical centers were enrolled. The diameter stenosis of target lesion was ≥70%, and lesion length was≤24 mm. The patients were randomly assigned to treatment with Firehawk stent (Firehawk stent group) or Xience V stent (Xience V stent group) groups by a web-based allocation system and was stratified by center. The late lumen loss after 9 months, target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction, or ischemia driven target lesion revascularization, patient-oriented composite endpoint (PoCE) which was a composite of all cause death, all cause myocardial infarction, or any revascularization, and stent thrombosis after 5 years were compared between the two groups. Results: (1) There were 2 patients without stent implantation dropped out of this trial. There were 227 patients in Firehawk stent group, and 231 patients in Xience V stent group. The baseline characteristics were similar between the two groups(all P>0.05). (2) The 9 months late lumen loss in Firehawk stent group was non-inferior to that in Xience V stent group ((0.13±0.24)mm vs. (0.13±0.18)mm, P=0.94). (3) A total of 442 (96.5%) patients completed 5 years clinical follow-up. There were no significant differences on 5-year TLF rate (6.0%(13/217) vs. 6.7% (15/225), P=0.77) and PoCE rate (12.0%(26/217) vs. 17.8% (40/225), P=0.09) between the Firehawk stent group and Xience V stent group. (4) Kaplan-Meier analysis showed that TLF rates between 1-5 years were similar in Firehawk stent group and Xience V stent group (5.7% and 6.6% respectively, HR=0.88, 95%CI 0.42-1.84, P=0.72). Land-Mark analysis showed that TLF rates bewteen 1-5 years were similar in Firehawk stent group and Xience V stent group (3.6% and 4.4% respectively, HR=0.83, 95%CI 0.34-2.00, P=0.67). Kaplan-Meier analysis showed that PoCE rates between 1-5 years were also similar in Firehawk stent group and Xience V stent group (11.4% and 17.3% respectively, HR=0.64, 95%CI 0.39-1.04, P=0.07). Land-Mark analysis showed that PoCE rates after 5 years were similar in Firehawk stent group and Xience V stent group (8.4% and 10.0% respectively, HR=0.66, 95%CI 0.40-1.10, P=0.11). (5) No stent thrombosis was documented in Firehawk stent group during the 5 years follow-up period, and there was 1 case of stent thrombosis in Xience V stent group after 3 years of stent implantation. Conclusion: TARGETⅠ trial results of 5 years follow up indicate the novel Firehawk stent have a durable safety and efficacy profile which is comparable to the Xience V stent in treating patients with single de novo coronary lesion.

Abstract
The dipeptidyl peptidase-4 (DPP-4) inhibitor saxagliptin has been found to reduce progressive albuminuria, but the exact mechanism of inhibition is unclear. Podocyte epithelial-to-mesenchymal transition (EMT) has emerged as a potential pathway leading to proteinuria in diabetic nephropathy (DN). Stromal cell–derived factor-1α (SDF-1α), one of the substrates of DPP-4, can activate the protein kinase A pathway and subsequently inhibit its downstream effector, transforming growth factor-β1 (TGF-β1), which induces podocyte EMT. Thus, this study was designed to test the hypothesis that saxagliptin reduces progressive albuminuria by preventing podocyte EMT through inhibition of SDF-1α cleavage in DN. The results of a series of assays, including ELISA, western blotting, and immunochemistry/immunofluorescence, showed that saxagliptin treatment obviously ameliorated urinary microalbumin excretion and renal histological changes in high-fat diet/streptozotocin-induced diabetic rats. Furthermore, saxagliptin-treated diabetic rats presented with suppression of DPP-4 activity/protein expression accompanied by restoration of SDF-1α levels, which subsequently hindered NOX2 expression and podocyte EMT. In vitro, we consistently observed that saxagliptin significantly inhibited increased DPP-4 activity/expression, oxidative stress and podocyte EMT. Application of an SDF-1α receptor inhibitor (AMD3100) to cultured podocytes further confirmed the essential role of SDF-1α in podocyte EMT inhibition. In sum, we demonstrated for the first time that saxagliptin treatment plays an essential role in ameliorating progressive DN by preventing podocyte EMT through a SDF-1α-related pathway, suggesting that saxagliptin could offer renoprotection and that SDF-1α might be a potential therapeutic target for DN.

Abstract
Emergent phenomena at polar-nonpolar oxide interfaces have been studied intensely in pursuit of next-generation oxide electronics and spintronics. Here we report the disentanglement of critical thicknesses for electron reconstruction and the emergence of ferromagnetism in polar-mismatched LaMnO_{3}/SrTiO_{3} (001) heterostructures. Using a combination of element-specific x-ray absorption spectroscopy and dichroism, and first-principles calculations, interfacial electron accumulation, and ferromagnetism have been observed within the polar, antiferromagnetic insulator LaMnO_{3}. Our results show that the critical thickness for the onset of electron accumulation is as thin as 2 unit cells (UC), significantly thinner than the observed critical thickness for ferromagnetism of 5 UC. The absence of ferromagnetism below 5 UC is likely induced by electron overaccumulation. In turn, by controlling the doping of the LaMnO_{3}, we are able to neutralize the excessive electrons from the polar mismatch in ultrathin LaMnO_{3} films and thus enable ferromagnetism in films as thin as 3 UC, extending the limits of our ability to synthesize and tailor emergent phenomena at interfaces and demonstrating manipulation of the electronic and magnetic structures of materials at the shortest length scales.

Abstract
BACKGROUND/AIMS Metabolic acidosis is a common consequence of end-stage renal disease (ESRD) which may result in a substantial adverse outcome. The effect of oral bicarbonate on the preservation of residual renal function (RRF) in peritoneal dialysis (PD) patients has been rarely reported. METHODS We randomly assigned 40 continuous ambulatory peritoneal dialysis (CAPD) patients to the oral bicarbonate group or placebo group at a 1: 1 ratio. All enrollments were followed for a duration of 104 weeks. We took residual creatinine clearance (CCr), a measure of residual renal function (RRF), as the primary outcome. Residual CCr was calculated as the average of urea and creatinine clearance from a 24-hour urine collection. RESULTS Thirteen patients in the placebo group and 15 patients in the treatment group completed the 104 weeks of follow-up with a comparable dropout rate (placebo group: 35% vs treatment group: 25%). Compared with the placebo group, serum bicarbonate in treatment group was significantly increased at each time point, and oral bicarbonate resulted in a slower declining rate of residual CCr (F=5.113, p=0.031). Baseline residual CCr at enrollment also had a significant effect on residual CCr (F=168.779, P<0.001). Charlson Comorbidity Index which was adopted to calculate a comorbidity score had no significant effect on residual CCr loss (F=0.168, P=0.685). CONCLUSION Oral bicarbonate may have a RRF preserving effect in CAPD patients, and a normal to high level of serum bicarbonate (≥24mmol/L) may be appropriate for RRF preservation.

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

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

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

Abstract
4077 Background: Napabucasin, a first-in-class cancer stemness inhibitor in clinical development, suppresses cancer stemness by targeting STAT3-driven gene transcription. Amcasertib targets multiple serine threonine stemness kinases and inhibits Nanog and other cancer stemness pathways. Preclinically, potent and broad-spectrum anti-cancer activity was observed in vitro and in vivo, alone and in combination with sorafenib. Methods: A phase Ib/II open-label, multi-center study in adult patients with advanced HCC who have not received prior systemic chemotherapy was performed to determine the safety, tolerability, and recommended Phase II dose (RP2D) ,according to the criteria for DLT and for dose-escalation of Napabucasin (Arm 1), administered at 160 mg BID (dose level I) and at 240 mg BID (dose level II) in combination with sorafenib and of Amcasertib (Arm 2), administered at 100 mg QD (dose level I) and at 200 mg QD (dose level II) in combination with sorafenib. Results: 20 pts were enrolled, 10 in Arm 1 and 10 in Arm 2. 12 patients were evaluable for DLT determination; 2 pts d/c prior to starting protocol treatment; 11 pts received evaluation by RECIST, 6 pts in Arm 1 and 5 pts in Arm 2. The safety profile was consistent with that of each agent as monotherapy and most common AEs were attributed to (Sor) and included rash, PPE, grade 1/2 diarrhea, nausea, abdominal cramps, and vomiting. No signs of drug-drug interactions were observed in pharmacokinetics. Among all patients who received RECIST evaluation, Disease Control Rate (DCR=CR+PR+SD) for Arm 1 was 100% (6/6pts) and 100% (5/5pts) for Arm 2. DCR in ITT Arm 1 population was 67% and 50% in Arm 2. Median OS is not yet reached. Conclusions: In this phase Ib study, RP2D were determined for napabucasin and amcasertib to be safely combined with sorafenib at full dose, showing encouraging anti-tumor activity in patients with HCC who have not received prior systemic chemotherapy. A randomized phase II is schedule to start. Clinical trial information: NCD02279719. [Table: see text]
