Abstract
BACKGROUND The effect of human 8-Oxoguanine DNA Glycosylase (hOGG1) on exogenous chemicals in esophageal squamous cell carcinoma (ESCC) remain unclear. The study plans to determine hOGG1 expression levels in ESCC and possible interactions with known environmental risk factors in ESCC. MATERIAL AND METHODS We analyzed levels of exposure to urinary nitrosamines in volunteers from high and low prevalence areas by GC-MS. And we performed the interaction between hOGG1 gene and nitrosamine disinfection by-products by analyzing hOGG1 gene expression in esophageal tissues. RESULTS In ESCC, nitrosamine levels were significantly increased and hOGG1 mRNA expression levels were significantly decreased. There was a statistically significant interaction between reduced hOGG1 mRNA levels and non-tap drinking water sources in ESCC. The apparent indirect association between ESCC and NMEA indicated that 33.4% of the association between ESCC and NMEA was mediated by hOGG1. CONCLUSION In populations which exposed to high levels of environmental pollutants NDMA, low expression of hOGG1 may promote the high incidence of esophageal cancer in Huai'an. hOGG1 may be a novel mediator in nitrosamine-induced esophageal tumorigenesis.

Abstract
BACKGROUNDS Allergic airway inflammation is prevalent worldwide and imposes a considerable burden on both society and affected individuals. This study aimed to investigate the therapeutic advantages of mesenchymal stem cells (MSCs) overexpressed interleukin-10 (IL-10) for the treatment of allergic airway inflammation, as both IL-10 and MSCs possess immunosuppressive properties. METHODS Induced pluripotent stem cell (iPSC)-derived MSCs were engineered to overexpress IL-10 via lentiviral transfection (designated as IL-10-MSCs). MSCs and IL-10-MSCs were administered intravenously to mice with allergic inflammation induced by ovalbumin (OVA), and the features of allergic inflammation including inflammatory cell infiltration, Th cells in the lungs, and T helper 2 cell (Th2) cytokine levels in bronchoalveolar lavage fluid (BALF) were examined. MSCs and IL-10-MSCs were co-cultured with CD4+ T cells from patients with allergic rhinitis (AR), and the levels of Th2 cells and corresponding type 2 cytokines were studied. RNA-sequence was performed to further investigate the potential effects of MSCs and IL-10-MSCs on CD4+ T cells. RESULTS Stable IL-10-MSCs were established and characterised by high IL-10 expression. IL-10-MSCs significantly reduced inflammatory cell infiltration and epithelial goblet cell numbers in the lung tissues of mice with allergic airway inflammation. Inflammatory cell and cytokine levels in BALF also decreased after the administration of IL-10-MSCs. Moreover, IL-10-MSCs showed a stronger capacity to inhibit the levels of Th2 after co-cultured with CD4+ T cells from patients with AR. Furthermore, we elucidated lower levels of IL-5 and IL-13 in IL-10-MSCs treated CD4+ T cells, and blockade of IL-10 significantly reversed the inhibitory effects of IL-10-MSCs. We also reported the mRNA profiles of CD4+ T cells treated with IL-10-MSCs and MSCs, in which IL-10 played an important role. CONCLUSION IL-10-MSCs showed positive effects in the treatment of allergic airway inflammation, providing solid support for the use of genetically engineered MSCs as a potential novel therapy for allergic airway inflammation.

Abstract
Objective: To explore risk factors associated with in-hospital mortality in patients requiring extracorporeal membrane oxygenation (ECMO) in the perioperative period of heart transplantation. Methods: The data of ECMO cases in the perioperative period of heart transplantation from the Chinese Society of Extracorporeal Life Support (CSECLS) between January 2017 and December 2021 were retrospectively analyzed. These patients were divided into the survival group and non-survival group according to their outcomes at discharge. The demographics, indications and complications of ECMO between the two groups were compared, and the related risk factors of poor prognosis were analyzed. Results: A total of 77 patients were included in the study, including 67 males and 10 females, with a median age [M(Q1, Q3)] of 48 (36, 59) years. Sixty-three patients (81.8%) were successfully withdrawn from the ECMO and 46 patients (59.7%) survived to discharge. The median ECMO time was 139 (92, 253) hours. Compared with the survival group, the non-survival group (n=31) had more patients with chronic kidney disease before surgery [22.6% (7/31) vs 4.3% (2/46), P=0.034], and a higher proportion of continuous renal replacement therapy (CRRT) during ECMO [74.2% (23/31) vs 50.0% (23/46), P=0.034]. Moreover, the non-survival group had longer duration of extracorporeal circulation [262 (195, 312) vs 201 (155, 261) min, P=0.056] and higher lactate value in the first 24 hours of ECMO support [2.7 (2.1, 4.7) vs 2.3 (1.4, 3.8) mmol/L, P=0.060], but the differences were not statistically significant. Multivariate logistic regression analysis showed that perioperative application of CRRT was an independent risk factor for poor prognosis in ECMO patients during heart transplantation (OR=19.345, 95%CI: 1.209-309.440, P=0.036). Conclusion: CRRT treatment during ECMO is a risk factor for in-hospital mortality in patients undergoing heart transplantation.

Abstract
Introduction Cotton (Gossypium hirsutum L.) is susceptible to long-term waterlogging stress; however, genomic information of cotton response mechanisms toward long days of waterlogging is quite elusive. Methods Here, we combined the transcriptome and metabolome expression level changes in cotton roots after 10 and 20 days of waterlogging stress treatment pertaining to potential resistance mechanisms in two cotton genotypes. Results and discussion Numerous adventitious roots and hypertrophic lenticels were induced in CJ1831056 and CJ1831072. Transcriptome analysis revealed 101,599 differentially expressed genes in cotton roots with higher gene expression after 20 days of stress. Reactive oxygen species (ROS) generating genes, antioxidant enzyme genes, and transcription factor genes (AP2, MYB, WRKY, and bZIP) were highly responsive to waterlogging stress among the two genotypes. Metabolomics results showed higher expressions of stress-resistant metabolites sinapyl alcohol, L-glutamic acid, galactaric acid, glucose 1-phosphate, L-valine, L-asparagine, and melibiose in CJ1831056 than CJ1831072. Differentially expressed metabolites (adenosine, galactaric acid, sinapyl alcohol, L-valine, L-asparagine, and melibiose) significantly correlated with the differentially expressed PRX52, PER1, PER64, and BGLU11 transcripts. This investigation reveals genes for targeted genetic engineering to improve waterlogging stress resistance to enhance abiotic stress regulatory mechanisms in cotton at the transcript and metabolic levels of study.

Abstract
Objective: To analyze the short-term effect of individual atmospheric PM2.5 exposure on the diversity, enterotype, and community structure of gut microbiome in healthy elderly people in Jinan, Shandong province. Methods: The present panel study recruited 76 healthy elderly people aged 60-69 years old in Dianliu Street, Lixia District, Jinan, Shandong Province, and followed them up five times from September 2018 to January 2019. The relevant information was collected by questionnaire, physical examination, precise monitoring of individual PM2.5 exposure, fecal sample collection and gut microbiome 16S rDNA sequencing. The Dirichlet multinomial mixtures (DMM) model was used to analyze the enterotype. Linear mixed effect model and generalized linear mixed effect model were used to analyze the effect of PM2.5 exposure on gut microbiome α diversity indices (Shannon, Simpson, Chao1, and ACE indices), enterotype and abundance of core species. Results: Each of the 76 subjects participated in at least two follow-up visits, resulting in a total of 352 person-visits. The age of 76 subjects was (65.0±2.8) years old with BMI (25.0±2.4) kg/m2. There were 38 males accounting for 50% of the subjects. People with an educational level of primary school or below accounted for 10.5% of the 76 subjects, and those with secondary school and junior college or above accounting for 71.1% and 18.4%. The individual PM2.5 exposure concentration of 76 subjects during the study period was (58.7±53.7) μg/m3. DMM model showed that the subjects could be divided into four enterotypes, which were mainly driven by Bacteroides, Faecalibacterium, Lachnospiraceae, Prevotellaceae, and Ruminococcaceae. Linear mixed effects model showed that different lag periods of PM2.5 exposure were significantly associated with a lower gut α diversity index (P<0.05 after correction). Further analysis showed that PM2.5 exposure was significantly associated with changes in the abundances of Firmicutes (Megamonas, Blautia, Streptococcus, etc.) and Bacteroidetes (Alistipes) (P<0.05 after correction). Conclusion: Short-term PM2.5 exposure is significantly associated with a decrease in gut microbiome diversity and changes in the abundance of several species of Firmicutes and Bacteroidetes in the elderly. It is necessary to further explore the underlying mechanisms between PM2.5 exposure and the gut microbiome, so as to provide a scientific basis for promoting the intestinal health of the elderly.

Abstract
Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Abstract
Objective: To investigate the relationship between glycemic variability and glycosylated hemoglobin (HbA1c) level during follow-up in elderly male patients with type 2 diabetes. Methods: Retrospective cohort study. A total of 200 elderly male patients who received continuous glucose monitoring from January 2007 to January 2011 were recruited in the Second Medical Center of PLA General Hospital. The subjects were divided into two groups according to baseline mean amplitude of glycaemic excursion (MAGE) level, including MAGE <3.9 mmol/L group (n=114) and MAGE ≥3.9 mmol/L group (n=86). The correlation between baseline MAGE and mean HbA1c during follow-up were evaluated by univariate Pearson correlation analysis and multivariate linear regression analysis. Results: Baseline characteristics including age, body mass index, waist circumference, smoking, drinking, fasting blood glucose, blood lipid and blood pressure were comparable between MAGE <3.9 mmol/L group and MAGE ≥3.9 mmol/L group. The average follow-up period was 12.5 years. The mean HbA1c during follow-up in MAGE ≥3.9 mmol/L group was significantly higher than that in MAGE <3.9 mmol/L group (7.23%±0.72% vs. 6.91%±0.77%, t=-2.94, P=0.004). The proportion of mean HbA1c <7.0% during follow-up in MAGE ≥3.9 mmol/L group was 44.2% (38/86), which was significantly lower than that in MAGE <3.9 mmol/L group [60.5% (69/114), χ2=5.26, P=0.022]. In univariate analysis, MAGE at baseline was correlated with the mean HbA1c during follow-up (r=0.306, P<0.001). Multivariate linear regression analysis suggested that the baseline MAGE remained an independent influential factor of mean HbA1c (β=0.09, 95%CI: 0.03 to 0.15, P=0.006, R2=0.31) after several confounding factors were adjusted. Conclusions: With the increased glycemic variability at baseline, mean HbA1c level during follow-up is accordingly elevated. The glycemic variability at baseline is independently related to mean HbA1c level during follow-up in elderly male patients with type 2 diabetes.

Abstract
Objective: To analyze the morphological changes of gray matter in clefts lip and palate (CLP) children using voxel-based morphometric (VBM) and surface-based morphometric (SBM) methods. So as to provide a reference for the neural mechanism of cleft palate speech disorder (CPSD) in CLP population. Methods: A total of 29 CLP children with CPSD who were admitted to Department of Oral & Maxillofacial Plastic & Tramuma Surgery, Capital Medical University School of Stomatology from January 2017 to January 2022 were selected (CLP group), including 9 males and 20 females, aged (9.6±3.2) years (5-17 years old). During the same period, 33 healthy children (healthy control group) were recruited in Beijing Children's Hospital, including 9 males and 24 females, aged (9.6±2.4) years (5-16 years). Results: There were no significant differences in age and gender between the healthy control group and the CLP group (t=-0.07, P=0.944; χ2=0.11, P=0.745). Compared with the healthy control group, the left inferior temporal gyrus, right inferior parietal angular gyrus, and left upper cerebellar gray matter volume in the CLP group were significantly decreased (P<0.05), and the volume of the right medial superior frontal gyrus was significantly increased (P<0.05). The left inferior frontal gyrus insula and the right insula cortical thickness of the subjects in the CLP group were significantly thinner [family-wise error rate (FWER) correction, P=0.035]. The right hemisphere cingulate gyrus isthmus sulcus index increased in the CLP group (FWER correction, P=0.040). Conclusions: CLP children with speech disorder have multiple language-related brain regions with reduced gray matter (GM) volume, decreased cortical thickness, and increased gyrificaition index. The abnormal changes in GM morphology in these brain regions may be related to the characteristics of cleft palate speech disorder in the CLP population.

Abstract
Temporal lobe epilepsy, with a variety of etiological, symptomatic, electrophysiological characteristics, has the highest incidence among all focal epilepsy, and a high rate of progression to refractory epilepsy. Surgery is an effective treatment, but traditional methods are usually difficult to accurately locate the epileptogenic zone, which may be resolved by stereotactic-electroencephalogram(SEEG) technique. Radiofrequency thermocoagulation and MRI-guided laser interstitial thermal therapy based on SEEG provide a new accurate and minimally invasive choice for refractory epilepsy patients with high surgical risk and difficulty.

Abstract
Objective: To investigate the long-term efficacy and safety of left cardiac sympathetic denervation(LCSD) for long QT syndrome(LQTS) patients with either recurrence on drug therapy intolerance/refusal. Methods: This study was a retrospective cohort study. The cases selected from 193 patients with LQTS who were enrolled in the Chinese Channelopathy Registry Study from November 1999 to November 2012. This study selected 28 LQTS patients with either recurrence on drug therapy intolerance/refusal and underwent LCSD surgery in the Peking University People's Hospital or Beijing Tongren Hospital. The patients were allocated into 3 groups: high-risk group(n=13, baseline QTc ≥550 ms or symptomatic in the first year of life or highly malignant genetics); intermediate-risk group(n=10, 500 ms≤baseline QTc<550 ms, symptomatic after the first year and without highly malignant genetics); low-risk group(n=5, baseline QTc<500 ms, symptomatic after the first year and without highly malignant genetics). LCSD was performed with the traditional supraclavicular approach or video assisted thoracoscopic surgery (VATS). Patients were regularly followed up until 20 years after the surgery. Data were collected before and 1 year after surgery and at the last follow-up. Patients' electrocardiograph(ECG), cardiac events and surgery-related complications were recorded. Kaplan-Meier survival analysis was used to determine the cardiac event-free survival based on different risk stratification and genotypes. Results: A total of 28 LQTS patients, aged 20.5 (15.0, 37.5) and underwent LCSD surgery, were enrolled in this study, including 23(82.1%) women. There were 11(39.3%) patients treated with traditional approach while 17(60.7%) with VATS-LCSD. There were 19(67.9%) patients had positive genetic test results, including 4 LQT1, 12 LQT2, 1 LQT1/LQT2 mixed type, and 2 Jervell-Lange-Nielsen (JLN) syndrome. The median follow-up period was 189.3(138.7, 204.9) months. The dropout rate was 10.7%(3/28) while 3 patients in the intermediate-risk group were lost to follow-up. Horner syndrome occurred in 1 patient (in the high-risk group). Sudden cardiac deaths were observed in 3 (12.0%) patients (all in the high-risk group), and 12 patients (48.0%) had syncope recurrences (2 in low-risk group, 3 in intermediate-risk group and 7 in high-risk group). A significant reduction in the mean yearly episodes of cardiac events was observed, from (3.5±3.3) before LCSD to(0.2±0.1) at one year after LCSD and (0.5±0.8) at last follow up(P<0.001). The mean QTc was shortened from (545.7±51.2)ms before the surgery to (489.0±40.1)ms at the last follow-up (P<0.001). Among the 20 patients with basic QTc ≥500 ms and completing the follow-up, the QTc intervals of 11(55.0%) patients were shortened to below 500 ms. The event free survival rates for any cardiac events after LCSD decreased sequentially in the low-, intermediate- and high-risk groups, and the difference was statistically significant (χ²=7.24, log-rank P=0.026). No difference was found in the event free survival rates among LQT1, LQT2 and undefined gene patients (χ²=5.20, log-rank P>0.05). Conclusions: LCSD surgery can reduce the incidence of cardiac events and shorten the QTc interval in patients with LQTS after the long-term follow-up. LCSD surgery is effective and safe for patients with LQTS ineffective or intolerant to drug therapy. However, high-risk patients are still at a high risk of sudden death after surgery and should be actively monitored and protected by combined therapies.

Abstract
Objective: To investigate whether the contralateral normal external auditory canal (EAC) skin graft can maintain the ear canal health after EAC reconstruction in unilateral congenital aural atresia (CAA) cases. Methods: A Zelen design randomized controlled study was used to collect unilateral CAA patients for EAC reconstruction prospectively (clinical trial registration number: ChiCTR2000032103). The patients were randomly divided into the control group and the trial group. The trial group used the contralateral normal EAC skin graft group (transplant part of the contralateral normal EAC skin to repair the atresia side for unilateral CAA patients), the control group all used scalp blade thick skin. We observed the EAC health and hearing results of the two groups after EAC reconstruction. Results: A total of 13 cases were enrolled from July 2020 to August 2021. There were eight patients in the trial group, including six males and two females, with an average age of 22.3 years (14-36 years). There were two patients with CAA on the left and six patients on the right. The average follow-up time was 8.8 months (4-14 months). There were five patients in the control group, all cases were male with an average age of 16.2 years (12-20 years). There were four patients with CAA on the left and one patient on the right. The average follow-up time was 7.0 months (2-14 months). In the trial group, eight cases of reconstructed EAC epithelium were healthy, one patient had cicatricial stenosis of EAC opening and lateralization of the tympanic membrane. The other patient had cicatricial stenosis of reconstructed EAC, this case also had scar hyperplasia of the contralateral EAC opening but recovered after soft packing and triamcinolone acetonide injection treatment. The healthy side EAC of the rest trial group had no scarring stenosis or local bone hyperplasia during long-term follow-up. In the control group, one patient was lost to follow-up and the other four patients had dry ears of reconstructed EAC, but easily to form crusts and needed to be cleaned repeatedly, one patient had lateralization of the tympanic membrane, the EAC epithelium was not healthy for long-term follow-up. The incidence of complications related to EAC reconstruction was lower than previous studies (χ²=5.55, P=0.018), and the average postoperative Air-Bone Gap increased (18.8±10.0)dB. Conclusion: By optimizing the EAC reconstruction technology, the health of the reconstructed EAC is improved compared with the previous study. After active intervention and treatment, there should be no scarring stenosis or local bone hyperplasia on the contralateral side EAC.

Abstract
Patients with cancer who receive doxorubicin (DOX) treatment can experience cardiac dysfunction, which can finally develop into heart failure. Oxidative stress is considered the most important mechanism for DOX-mediated cardiotoxicity. Rutaecarpine (Rut), a quinazolinocarboline alkaloid extracted from Evodia rutaecarpa was shown to have a protective effect on cardiac disease. The purpose of this study is to investigate the role of Rut in DOX-induced cardiotoxicity and explore the underlying mechanism. Intravenous injection of DOX (5 mg/kg, once a week) in mice for 4 weeks was used to establish the cardiotoxic model. Echocardiography and pathological staining analysis were used to detect the changes in structure and function in the heart. Western blot and real-time PCR analysis were used to detect the molecular changes. In this study, we found that DOX time-dependently decreased cardiac function with few systemic side effects. Rut inhibited DOX-induced cardiac fibrosis, reduction in heart size, and decrease in heart function. DOX-induced reduction in superoxide dismutase (SOD) and glutathione (GSH), enhancement of malondialdehyde (MDA) was inhibited by Rut administration. Meanwhile, Rut inhibited DOX-induced apoptosis in the heart. Importantly, we further found that Rut activated AKT or nuclear factor erythroid 2-related factor 2 (Nrf-2) which further upregulated the antioxidant enzymes such as heme oxygenase-1 (HO-1) and GSH cysteine ligase modulatory subunit (GCLM) expression. AKT inhibitor (AKTi) partially inhibited Nrf-2, HO-1, and GCLM expression and abolished the protective role of Rut in DOX-induced cardiotoxicity. In conclusion, this study identified Rut as a potential therapeutic agent for treating DOX-induced cardiotoxicity by activating AKT.

Abstract
Background Genetic polymorphisms in the PPARD and NOS1AP is associated with type 2 diabetes mellitus (T2DM); however, there is no evidence about its impact on the therapeutic efficacy of nateglinide. This study was designed to investigate a potential association of PPARD rs2016520 (T/C) and NOS1AP rs12742393 (A/C) polymorphisms with efficacy of nateglinide in newly diagnosed Chinese patients with type 2 diabetes mellitus (T2DM). Methods Sixty patients with newly diagnosed T2DM were enrolled to identify PPARD rs2016520 and NOS1AP rs12742393 genotypes using the polymerase chain reaction-restriction fragment length polymorphism assay (PCR–RFLP). All subjects were treated with nateglinide (360 mg/day) for 8 weeks. Anthropometric measurements, clinical laboratory tests were obtained at baseline and after 8 weeks of nateglinide treatment. Results After nateglinide treatment for 8 consecutive weeks, patients with at least one C allele of PPARD rs2016520 showed a smaller decrease in post plasma glucose (PPG), homeostasis model assessment for beta cell function (HOMA-B) than those with the TT genotype did (P < 0.05). In patients with the AA genotype of NOS1AP rs12742393, the drug showed better efficacy with respect to levels of fasting plasma glucose (FPG), fasting serum insulin (FINS), HOMA-B and homeostasis model assessment for insulin resistance (HOMA-IR) than in patients with the AC + CC genotype (P < 0.05). NOS1AP rs12742393 genotype distribution and allele frequency were associated with responsiveness of nateglinide treatment (P < 0.05). Conclusions The PPARD rs2016520 and NOS1AP rs12742393 polymorphisms were associated with nateglinide monotherapy efficacy in Chinese patients with newly diagnosed T2DM.

Abstract
OBJECTIVE To evaluate the impact of water pollutants, water levels and meteorological factors on the Oncomelania hupensis density in Eastern Dongting Lake regions, so as to provide insights into schistosomiasis control. METHODS O. hupensis snails were surveyed using a systematic sampling method in snail-infested marshlands in Eastern Dongting Lake regions from 2007 to 2014, and data pertaining to water pollutants, water levels and meteorological factors were collected. The duration of submergence and the date of the start of submergence were calculated. The snail density and its influencing factors were descriptively analyzed, and a linear mixed model was generated to examine the impacts of variables on the snail density. In addition, smooth curves were fitted to investigate the relationship between snail density and variables. RESULTS The snail density appeared a fluctuation in Eastern Dongting Lake regions during the period from 2007 to 2014, with the highest density on October, 2010 (52.79 snails/0.1 m2) and the lowest density on January 2009 (2.15 snails/0.1 m2). Linear mixed-model analysis showed that permanganate index, total phosphorus and the date of the start of submergence affected the snail density (t = 6.386, -2.920 and -3.892, all P values < 0.01). Smooth curve analysis revealed that the associations of the snail density with the permanganate index and total phosphorus appeared an approximately quadratic curve. After the end of April, the earlier date of the start of submergence resulted in a higher snail density. CONCLUSIONS Permenganate index, total phosphorus and the date of the start of submergence affect the O. hupensis snail density in Eastern Dongting Lake regions.

Abstract
Epigenetic alterations occur as organisms age, and lead to chromatin deterioration, loss of transcriptional silencing and genomic instability. Dysregulation of the epigenome has been associated with increased susceptibility to age-related disorders. In this study, we aimed to characterize the age-dependent changes of the epigenome and, in turn, to understand epigenetic processes that drive aging phenotypes. We focused on the aging-associated changes in the repressive histone marks H3K9me3 and H3K27me3 in C. elegans. We observed region-specific gain and loss of both histone marks, but the changes are more evident for H3K9me3. We further found alteration of heterochromatic boundaries in aged somatic tissues. Interestingly, we discovered that the most statistically significant changes reflected H3K9me3-marked regions that are formed during aging, and are absent in developing worms, which we termed "aging-specific repressive regions" (ASRRs). These ASRRs preferentially occur in genic regions that are marked by high levels of H3K9me2 and H3K36me2 in larval stages. Maintenance of high H3K9me2 levels in these regions have been shown to correlate with a longer lifespan. Next, we examined whether the changes in repressive histone marks lead to de-silencing of repetitive DNA elements, as reported for several other organisms. We observed increased expression of active repetitive DNA elements but not global re-activation of silent repeats in old worms, likely due to the distributed nature of repetitive elements in the C. elegans genome. Intriguingly, CELE45, a putative short interspersed nuclear element (SINE), was greatly overexpressed at old age and upon heat stress. SINEs have been suggested to regulate transcription in response to various cellular stresses in mammals. It is likely that CELE45 RNAs also play roles in stress response and aging in C. elegans. Taken together, our study revealed significant and specific age-dependent changes in repressive histone modifications and repetitive elements, providing important insights into aging biology.

Abstract
Marine-derived fungi are a treasure house for the discovery of structurally novel secondary metabolites with potential pharmaceutical value. In this study, a pair of new nor-bisabolane derivative enantiomers (±)−1 and two new phthalides (4 and 5), as well as four known metabolites, were isolated from the culture filtrate of the marine algal-derived endophytic fungus Penicillium chrysogenum LD-201810. Their structures were established by detailed interpretation of spectroscopic data (1D/2D NMR and ESI-MS). The optical resolution of compound (±)−1 by chiral HPLC successfully afforded individual enantiomers (+)−1 and (−)−1, and their absolute configurations were determined by TDDFT-ECD calculations. Compound (±)−1 represents the first example of bisabolane analogs with a methylsulfinyl substituent group, which is rare in natural products. All of the isolated compounds 1–7 were evaluated for their cytotoxic activity against A549, BT-549, HeLa, HepG2, MCF-7, and THP-1 cell lines, as well as for antifungal activity against four plant pathogenetic fungi (Alternaria solani, Botrytis cinerea, Fusarium oxysporum, and Valsa mali). Compound 2, a bisabolane-type sesquiterpenoid, was shown to possess excellent activity for control of B. cinerea with half-maximal inhibitory concentration (IC50) of 13.6 μg/mL, whereas the remaining investigated compounds showed either weak or no cytotoxic/antifungal activity in this study.

Abstract
Annexin A1 (AnxA1, also known as lipocortin-1), is a calcium-dependent phospholipid binding protein with diverse functions. Previous studies have indicated that AnxA1 is associated with age-related β-cell dysfunction and aging, which lead to decreased β-cell proliferation capacity. However, it has been uncertain whether AnxA1 affects the proliferation of pancreatic beta (β) cells. In the present study, we reduced AnxA1 expression in the MIN6 islet β-cell line using small interfering RNA (AnxA1-siRNA), then measured cell cycle distribution and cellular proliferation. We also measured the expression levels of cell cycle-related proteins such as cyclin D1, cyclin E, and cyclin-dependent kinase 2 (CDK2) by Western blot analysis. We investigated the phosphatidylinositol 3-kinase (PI3K)/ serine/threonine protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway to explore the potential mechanism underlying the observed effects. Knockdown of AnxA1 expression using siRNA reduced the rates of MIN6 cell proliferation. The proportions of cells in S and G2/M phases also decreased upon inhibition of AnxA1. Moreover, AnxA1 protein expression in MIN6 cells was positively related to the protein levels of cyclin D1, cyclin E, and CDK2. Activation of the PI3K/Akt/mTOR signaling pathway by AnxA1 may be involved in the signaling cascade to regulate cell proliferation. This study identified a positive correlation between AnxA1 protein and pancreatic β-cell proliferation. AnxA1 protein expression might affect the proliferation of MIN6 cells via regulation of cyclin D1, cyclin E, and CDK2 proteins, as well as the PI3K/Akt/mTOR signaling pathway.

Abstract
Podocyte injury following abnormal podocyte autophagy plays an indispensable role in diabetic nephropathy (DN), therefore, restoration of podocyte autophagy is considered as a feasible strategy for the treatment of DN. Here, we investigated the preventive effects of sarsasapogenin (Sar), the main active ingredient in Anemarrhena asphodeloides Bunge, on the podocyte injury in diabetic rats, and tried to illustrate the mechanisms underlying the effects in high glucose (HG, 40 mM)-treated podocytes (MPs). Diabetes model was established in rats with single streptozocin (60 mg· kg-1) intraperitoneal administration. The rats were then treated with Sar (20, 60 mg· kg-1· d-1, i.g.) or a positive control drug insulin (INS) (40 U· kg-1· d-1, i.h.) for 10 weeks. Our results showed that both Sar and insulin precluded the decreases of autophagy-related proteins (ATG5, Beclin1 and LC3B) and podocyte marker proteins (podocin, nephrin and synaptopodin) in the diabetic kidney. Furthermore, network pharmacology was utilized to assess GSK3β as the potential target involved in the action of Sar on DN and were substantiated by significant changes of GSK3β signaling in the diabetic kidney. The underlying protection mechanisms of Sar were explored in HG-treated MPs. Sar (20, 40 μM) or insulin (50 mU/L) significantly increased the expression of autophagy- related proteins and podocyte marker proteins in HG-treated MPs. Furthermore, Sar or insulin treatment efficiently regulatedphosphorylation at activation and inhibition sites of GSK3β. To sum up, this study certifies that Sar meliorates experimental DN through targeting GSK3β signaling pathway and restoring podocyte autophagy.

Abstract
Objective: To investigate the effect and satisfaction of using the postauricular tongue-shaped flap combined with deep fascia suspension in correcting severe cup ear malformation. Methods: Between August 2018 and November 2019, nine cases (10 ears) of Tanzer type Ⅲ severe cup ear malformation were treated with postauricular tongue-shaped flap combined with deep fascia suspension in this study. Results: Nine cases primary healed without hematoma, infection or skin necrosis, except one case with postoperative incision dehiscence. The cup ear deformity was significantly improved after the operation, the helix was intact, and the anti-helix was visible. The length, width, and circumference of the auricle were significantly enlarged three months following surgeries. There were no other complications except 1 patient recurrence 12 months after surgery. The patients were highly satisfied with the results of the surgery. Conclusions: Although the aesthctic of the reconstructed auricle is insufficient, this new technology makes full use of the autologous auricle tissue to correct severe cup ear malformation with good results.

Abstract
Group 2 innate lymphoid cells (ILC2s) are recognized as key controllers and effectors of type 2 inflammation. Mesenchymal stem cells (MSCs) have been shown to alleviate type 2 inflammation by modulating T lymphocyte subsets and decreasing TH 2 cytokine levels. However, the effects of MSCs on ILC2s have not been investigated. In this study, we investigated the potential immunomodulatory effects of MSCs on ILC2s in peripheral blood mononuclear cells (PBMCs) from allergic rhinitis patients and healthy subjects. We further investigated the mechanisms involved in the MSC modulation using isolated lineage negative (Lin- ) cells. PBMCs and Lin- cells were cocultured with induced pluripotent stem cell-derived MSCs (iPSC-MSCs) under the stimulation of epithelial cytokines IL-25 and IL-33. And the ILC2 levels and functions were examined and the possible mechanisms were investigated based on regulatory T (Treg) cells and ICOS-ICOSL pathway. iPSC-MSCs successfully decreased the high levels of IL-13, IL-9, and IL-5 in PBMCs in response to IL-25, IL-33, and the high percentages of IL-13+ ILC2s and IL-9+ ILC2s in response to epithelial cytokines were significantly reversed after the treatment of iPSC-MSCs. However, iPSC-MSCs were found directly to enhance ILC2 levels and functions via ICOS-ICOSL interaction in Lin- cells and pure ILC2s. iPSC-MSCs exerted their inhibitory effects on ILC2s via activating Treg cells through ICOS-ICOSL interaction. The MSC-induced Treg cells then suppressed ILC2s by secreting IL-10 in the coculture system. This study revealed that human MSCs suppressed ILC2s via Treg cells through ICOS-ICOSL interaction, which provides further insight to regulate ILC2s in inflammatory disorders.

Abstract
The physical form of starter feed may affect the gastrointestinal development and the performance of ruminant. However, little information is available on how changes in the physical forms of starter feed influence the performance of lambs, especially during the pre- and post-weaning periods. The aim of this study was to investigate the effects of different physical forms of starter feeds on growth performance, nutrient digestibility, gastrointestinal enzyme activity, and morphology of pre- and post-weaning lambs. Twenty-four 8-day-old male Hu lamb (5.04 ± 0.75 kg BW) were randomly assigned to one of two dietary treatments: 1) a pelleted starter (PS) feed and 2) a textured starter (TS) feed, which included coarse mashed steam-flaked corn. From eight to thirty-five days of age (pre-weaning), the lambs were bottle-fed milk replacer (MR) at 2% of BW measured on day 8. All lambs were weaned at day 35 when feeding of MR was stopped. Six lambs for each treatment were euthanized at 21 or 42 days of age for sampling. The following results are obtained by variance analysis: TS lambs had a greater (P < 0.05) final BW, higher apparent digestibility of starch and ether extract, activities of α-amylase pre- or post-weaning, and higher (P < 0.05) average dry matter intake and lipase post-weaning in small intestine contents and had a trend of significantly higher average daily gain post-weaning (P = 0.07). Rumen development analysis of TS lambs showed a significantly higher (P < 0.05) relative weight of rumen post-weaning, greater papillae length, increased circular and layered muscle, increased sectional area pre- and post-weaning, and increased rumen papillae width post-weaning. Textured starter treatment increased the villus height and villus width (except jejunum pre-weaning) of the whole small intestine and villus height to crypt depth ratio of jejunum and ileum during the whole period and tended to increase the relative weight of the rumen pre-weaning (P = 0.07). The results indicated that TS feeding is more beneficial to lambs over the weaning transition than PS in promoting gastrointestinal development, intestinal enzyme activities, nutrient digestibility, and growth performance. The findings provide new insights into the selection of physical forms of starter feeds in lamb production. Further research with more animals and female lambs is needed to obtain a more complete conclusion.

Abstract
Abstract Objective To estimate sex based on patella measurements of Sichuan Han population by computed tomography three-dimensional volume reconstruction technique, and to explore the application value of patella in sex estimation. Methods CT three-dimensional volume reconstruction images of patella of 250 individuals were collected, the four measurement indicators including patellar length, patellar width, patellar thickness, and patellar volume were measured. The t-test was used to determine measurement indicators with sex differences. Fisher discriminant analysis was used to establish the sex discriminant function and the prediction accuracy was calculated by leave-one-out cross validation. Results The sex differences of the four measurement indicators had a statistical significance (P<0.05). The accuracy rate of the univariate discriminant function established by the patellar length was the highest (82.0%). The accuracy rates of the all indicators discriminant function and the stepwise discriminant function were 80.4% and 81.6%, respectively. Conclusion It is feasible and accurate to estimate sex of Sichuan Han population by patella measurements with CT three-dimensional volume reconstruction technique. The method may be used as an alternative for sex estimation of Sichuan Han population when other bones with higher accuracy are not available.

Abstract
In this study, a series of 3-(4-phenyl-1H-imidazol-2-yl)-1H-pyrazole derivatives were designed, synthesized, and evaluated for their biological activities. Upon performing kinase assays, most of the compounds exhibited potent inhibition against JAK2/3 and Aurora A/B with the IC50 values ranging from 0.008 to 2.52 μM. Among these derivatives, compound 10e expressed the most moderate inhibiting activities against all the four kinases with the IC50 values of 0.166 μM (JAK2), 0.057 μM (JAK3), 0.939 μM (Aurora A), and 0.583 μM (Aurora B), respectively. Moreover, most of the derived compounds exhibited potent cytotoxicity against human chronic myeloid leukemia cells K562 and human colon cancer cells HCT116, while compound 10e expressed antiproliferative activities against K562 (IC50=6.726 μM). According to western blot analysis, compound 10e down-regulated the phosphorylation of STAT3, STAT5, Aurora A, and Aurora B in a dose-dependent manner in K562 and HCT116 cells. Cell cycle analysis revealed that compound 10e inhibited the proliferation of cells by inducing cell cycle arrest in the G2 phase. The molecular modeling suggested that compound 10e could maintain a binding mode similar to the binding mode of AT9832, a common JAK 2/3 and Aurora A/B kinases multi-target kinase inhibitor. Therefore, compound 10e might be a potential agent for cancer therapy deserving further research.

Abstract
Objective: To investigate the feasibility and safety of minimally invasive radical prostatectomy for prostate cancer patients without preoperative prostate biopsy in the new era of the continuous development of comprehensive new imaging diagnostic mode and minimally invasive surgery technology. Methods: From August 2018 to October 2019, 17 patients with prostate cancer were enrolled in this study in the Cancer Hospital, Chinese Academy of Medical Sciences. All patients were highly suspected of prostate cancer by PSMA-PET/CT-based imaging diagnostic techniques and underwent 3D laparoscopic radical prostatectomy without prostate biopsy. The perioperative data, postoperative pathology, postoperative complications and follow-up results were recorded and analyzed. Results: The average age of 17 patients with prostate cancer was (65±7) years. The body mass index (BMI) average was (24.4±3.0) kg/m(2). The American Society of Anesthesiologists (ASA) score was 1 (1-2) and the Charlson comorbidity index (CCI) score was 1 (0-4). The preoperative value of PSA was (19±11) μg/L. The PSMA PET/CT showed abnormally high expression foci and the great possibility of prostate cancer for all the 17 patients. Prostate puncture biopsy: the results of prostate biopsy were negative in 3 cases. The digital rectal examination found that the prostate volume was Ⅰ or Ⅱ degree large, 10 cases touched hard and the nodule was touched in two cases. Three patients had undergone a previous prostate biopsy, but prostate cancer was not found. All the 17 operations were successfully performed without conversion to open surgery. The surgery time was (85±21) (range from 45 to 120) min, the estimated blood loss was (25±18) (range from5 to 100) ml, the time of intake of liquid diet was (14.3±4.4) h, the intestinal recovery time was (23±10) h, the postoperative activity time was (22±7) h, the drainage duration was (3.7±0.8) d, the postoperative hospital stay was (4.9±1.2) days, and the catheter removal time was (7.4±1.5) days. In the early postoperative period (within 30 days after surgery), no obvious complications occurred. The postoperative final pathology confirmed that all the 17 specimens were prostate cancer. After a median follow-up of 6.5 months, the patient's urinary control rate reached 81.3% at postoperative 1 month, 92.3% at postoperative 3 months after surgery, and the urinary control rate reached 100% at postoperative 6 months. Postoperative PSA value was (0.08±0.08) μg/L, significantly lower than preoperative PSA level (P<0.001). There was significant difference between the preoperative and postoperative QOL (Quality of life) score (57±5 and 47±5 respectively, P<0.001) which indicated that the patients' postoperative quality of life was greatly improved. Conclusions: It is safe and feasible to perform minimally invasive radical prostatectomy without preoperative prostate biopsy for patients with highly suspected prostate cancer by comprehensive diagnostic mode based on modern new imaging technology.

Abstract
PURPOSE This retrospective study aimed to assess the association between obesity, gender, and specific clinicopathological features in patients with papillary thyroid cancer (PTC) and whether diagnostic ultrasonography (US) is adversely affected by obesity in these patients. MATERIALS AND METHODS This study retrospectively analyzed 13,995 adult patients with PTC from a single medical center in China. Data stratification was performed to assess the association of obesity with US features and aggressive clinicopathological features in different models according to the World Health Organization Body Mass Index (WHO-BMI) and Chinese BMI classification (CN-BMI). The odds ratio (OR) of malignant US features and aggressive clinicopathological features was calculated from binary logistic regression models. RESULTS The BMI, obesity ratio, malignant US features, and aggressive pathological characteristics of males were significantly higher than those of females. After adjusting for confounding factors, the association of obesity with malignant US features and aggressive pathological characteristics was found to be sex-dependent. Next, obesity (WHO-BMI) was found to have an "interfering effect" on the US assessment of PTC (OR = 0.754, 95% CI 0.609-0.932, P = 0.009) in women. Among both sexes, obesity (WHO-BMI) increased the risk of tumor size (ORmale = 1.539 and ORfemale = 1.521) and multifocality (ORmale = 1.659 and ORfemale = 1.449). However, obesity did not increase the risk of capsular invasion or tumor staging in males. The above results are consistent with the CN-BMI. In addition, age was found to have an "interfering effect" on the US evaluation of malignant nodules in both sexes. CONCLUSION The results of our study confirm that higher BMI is significantly associated with aggressive clinicopathological features of PTC. Gender differences were present with obesity ratios and aggressive clinicopathological features being significantly higher in men.

Abstract
BACKGROUND Surgical resection is regarded as the only potentially curative treatment option for patients with metastatic colorectal cancer (CRC). The National Comprehensive Cancer Network clinical practice guidelines do not recommend palliative surgery unless there is a risk of severe symptoms. However, accumulating evidence has shown that palliative surgery is associated with more favorable outcomes for patients with metastatic CRC.
AIM To investigate the separate role of palliative primary tumor resection for patients with stage IVA (M1a diseases) and stage IVB (M1b diseases) colorectal adenocarcinoma (CRA).
METHODS CRA patients diagnosed from 2010 to 2015 with definite M1a and M1b categories according to the 8th edition of American Joint Committee on Cancer staging system were selected from the Surveillance Epidemiology and End Results (SEER) database. To minimize potential selection bias, the data were adjusted by propensity score matching (PSM). Baseline characteristics, including gender, year of diagnosis, age, marital status, primary site, surgical information, race, grade, chemotherapy, and radiotherapy, were recorded and analyzed. Univariate and multivariate analyses were performed to explore the separate role of palliative surgery for patients with M1a and M1b diseases.
RESULTS A total of 19680 patients with metastatic CRA were collected from the SEER database, including 10399 cases of M1a diseases and 9281 cases of M1b diseases. Common independent prognostic factors for both M1a and M1b patients included year of diagnosis, age, race, marital status, primary site, grade, surgery, and chemotherapy. After PSM adjustment, 3732 and 3568 matched patients in the M1a and M1b groups were included, respectively. Patients receiving palliative primary tumor resection had longer survival time than those without surgery (P < 0.001). For patients with M1a diseases, palliative resection could increase the median survival time by 9 mo; for patients with M1b diseases, palliative resection could prolong the median survival time by 7 mo. For M1a diseases, patients with lung metastasis had more clinical benefit from palliative resection than those with liver metastasis (15 mo for lung metastasis vs 8 mo for liver metastasis, P < 0.001).
CONCLUSION CRA patients with M1a diseases gain more clinical benefits from palliative primary tumor resection than those with M1b diseases. Those patients with M1a (lung metastasis) have superior long-term outcomes after palliative primary tumor resection.

Abstract
Objective: To Summarize the experience of pump-controlled retrograde trial off (PCRTO) in the process of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) withdrawal in adult patients. Methods: Adult patients who received ECMO assistance in Intensive Care Unit for Cardiac Surgery from March to July 2019 were collected. According to our strategies, PCRTO was used if the patients can wean from VA-ECMO and hemodynamic indexes were recorded during the process. The statistics data was collected, including the 48 hours survival rate, ECMO re-assistance rate, thrombus complications, Intensive Care Unit (ICU) stay time and hospital stay time after weaning from VA-ECMO. The patients who failed in the test were continued to be assisted by ECMO. Results: There were 46 patients assisted by VA-ECMO in our center. In total, 21 adults who met the offline test standard underwent 26 PCRTOs, including 10 male adults (47.6%), with an age of 65 (55, 68) years old. Eighteen adults passed the withdrawal test. No new thrombus was found in the arteriovenous ultrasound of the lower extremity after weaning from ECMO, and no pulmonary embolism was found in the chest X-ray. The success rate of weaning from ECMO was 69.23%(18/26). The D-dimer decreased [584(348,2 107)μg/L vs 1 440(631,2 916)μg/L, P=0.014] and the left ventricular ejection fraction (LVEF) increased (51.4%±8.5% vs 46.9%±10.6%, P=0.013) on the next day after weaning. There were significant differences in heart rate (HR), central venous pressure (CVP), oxygenation index and lactate (Lac) during the PCRTO in the group which involved the cases of the 8 failed experiments (all P<0.05). Compared with the failure group, there were significant differences in age, blood flow rate, CVP before the test, HR, pulse oxygen saturation(SpO(2)), CVP, Lac and oxygenation index after the test, and the variations of SpO(2), CVP and Lac. Conclusion: PCRTO is a simple, reversible, safe and effective weaning method. It can be used in the process of VA-ECMO withdrawal in adult patients.

Abstract
Objective: To establish Chinese diet balance index for preschool children(DBI_C), and evaluate the dietary quality of Chinese preschool children. Methods: DBI_C was established according to the methods establishing DBI_16 and the recommended intake of different kinds of food for preschool children. Three scoring methods [low bound score (LBS), high bound score (HBS), diet quality distance (DQD)] were used to evaluate the dietary quality of preschool children selected from the 2010-2012 China National Nutrition and Health Surveillance. Scores [P50(P25, P75)] were compared to reflect the diet quality of preschool children in different regions. Results: DBI_C scores for cereals of preschool children from big city, middle and small city, normal rural area, and poor rural area were 0.0 (-2.0, 6.0), 0.0 (0.0, 6.0), 4.0 (0.0, 10.0), and 10.0 (2.0, 12.0), respectively (P<0.001), indicating that the intakes of cereals of preschool children were adequate. Scores for animal food of preschool children from four types of location were 0.0 (-2.0, 2.0), 0.0 (-6.0, 2.0), -4.0 (-6.0, 0.0), and -6.0 (-8.0,-2.0), respectively (P<0.001), indicating that the intakes of animal food of rural preschool children were inadequate. Scores for vegetable and fruit, milk and soybean were both less than 0 (P<0.001), indicating that the intakes of these food were insufficient in both urban and rural area. Scores of LBS, HBS and DQD were 24.0 (18.0, 30.0), 8.0 (3.0, 13.0) and 33.0(26.0, 39.0). Children without diet insufficient problem in four type of location accounted for 30.8%, 7.8%, 4.3% and 1.1%, respectively (P<0.001). Children without diet excessive problem accounted for 54.0%, 57.3%, 52.9% and 32.6%, respectively (P<0.001). Children without diet imbalance problem were 10.6%, 1.1%, 1.3% and 0.3%, respectively (P<0.001). Conclusion: Diet quality of urban preschool children is better than that of rural preschool children. Dietary imbalance is the main problem among Chinese preschool children.

Abstract
Background Several studies probed into the connection between esophageal cancer (EC) risk and PRKAA1 rs13361707 C/T
polymorphism, but obtained insignificant findings. Methods In this study, 814 EC cases and 961
controls from Eastern China were recruited to validate the relationship between this polymorphism and EC susceptibility. Results Data suggested rs13361707 C/T
polymorphism in PRKAA1 gene was significantly related with a lower risk for EC. Such significant connection was also uncovered in subgroups of males, smokers, drinkers and individuals with age ≥ 60 years. In addition, this polymorphism
was linked with the pathological grading, distant metastasis, and histology of EC. Conclusion In summary, PRKAA1 rs13361707 C/T
polymorphism is related to the risk and clinical properties of EC patients in East China.

Abstract
BACKGROUND Mycophenolate has been shown to be effective in glomerular disease. However, the role of mycophenolate in the first-line treatment of adult-onset idiopathic minimal change disease (MCD) has not been systematically studied in a randomized fashion. AIM To evaluate the therapeutic efficacy of enteric-coated mycophenolate sodium combined with low-dose corticosteroid as first-line treatment for MCNS. DESIGN A prospective, open-label, randomized clinical trial. METHODS Twenty adult patients with biopsy proven MCD were recruited and randomly assigned to receive either enteric-coated Mycophenolate Sodium (EC-MPS) plus low-dose prednisolone (Group 1: Prednisolone 0.25 mg/kg/day, n = 10) or standard-dose prednisolone (Group 2: Prednisolone 1 mg/kg/day, n = 10). RESULTS After 24 weeks of therapy, eight patients in Group 1 vs. seven of patients in Group 2 achieved complete remission (P = 0.606). Both groups showed a significant reduction of urine protein excretion (P < 0.05) and increased serum albumin (P < 0.001) vs. baseline levels. However, no significant between-group differences were demonstrated. The relapse rate was also similar in both groups. Both treatment regimens were well tolerated but there were more patient reported adverse effects in the standard-dose prednisolone group. CONCLUSION EC-MPS plus low-dose prednisolone is non-inferior to standard-dose prednisolone therapy in inducing clinical remission and preventing relapse in adult-onset idiopathic MCD and is associated with better tolerability and less adverse effects. This trial is registered with the ClinicalTrials.gov number NCT01185197.

Abstract
OBJECTIVE To analyze the endemic situation of schistosomiasis in Hunan Province in 2019, so as to provide insights into the achievement of transmission interruption of schistosomiasis in the province in 2020. METHODS The data pertaining to Schistosoma japonicum infections in humans and livestock and snail status were captured from Hunan Province in 2019 and analyzed. RESULTS Schistosomiasis was endemic in 281 townships (towns) from 41 counties (districts) of 6 cities in Hunan Province by the end of 2019. A total of 991 900 persons received blood testing in Hunan Province in 2019, and 22 773 were positive for the blood testing, with sero-prevalence of 2.30%. All stool examinations were negative in 22 933 individuals detected. The high sero-prevalence was seen in Nanxian County, Anxiang County and Ziyang District. Currently, there were 5 034 cases with advanced schistosomiasis detected in Hunan Province, and they were predominantly identified in Yuanjiang City, Heshan District and Yueyang County. There were 44 963 bovines fenced in schistosomiasis-endemic villages in Hunan Province in 2019, which were predominantly distributed in Yuanjiang City, Hanshou County and Ziyang District, and no positives were detected in 1 996 bovines receiving blood testing or 20 684 bovines receiving stool examinations. In 2019, there were snail habitats of 1.73 billion m2 found in Hunan Province, which were mainly found in Yuanjiang City, Hanshou County and Yueyang County. CONCLUSIONS The endemic situation of schistosomiasis further decreases in Hunan Province in 2019; however, there is still a risk of schistosomiasis transmission in local areas of the province.

Abstract
Objective: To investigate the differences in efficacy between drug-eluting beads transbronchial arterial chemoembolization (DEB-BACE) combined with systemic chemotherapy and systemic chemotherapy alone for unresectable lung squamous cell carcinoma. Methods: Totally 60 cases of unresectable lung squamous cell carcinoma undergoing systemic chemotherapy in Yancheng Third People Hospital were retrospectively selected as the research object. According to patients' wishes, they were divided into chemotherapy-only group (group A) and combined treatment group (group B). Group A received gemcitabine combined with cisplatin chemotherapy. DEB-BACE was applied in the first half, and systemic chemotherapy was administered in the second half (starting 3 d after BACE). The first half and the second half of the chemotherapy dose were 1/2 of the drug dose in the chemotherapy alone group. The short-term efficacy, incidence of toxic side effects, peripheral blood T lymphocyte subsets, serum vascular endothelial growth factor (VEGF) levels, and survival time were compared between the two groups. Results: After 2 cycles of treatment, the total effective rates of group A and group B were 50.0% (15/30) and 76.7% (23/30) (P<0.05), the incidence of nausea and vomiting (63.3% vs 20.0%), decreased appetite (76.7% vs 43.3%), hair loss (86.7% vs 40.0%), and bone marrow suppression (40.0% vs 10.0%) in group A were higher than in group B (all P<0.05). After 2 cycles of treatment, the levels of CD3(+), CD4(+)and CD4(+)/CD8(+)in the two groups were higher than before treatment (group A: 47.7%±6.6% vs 52.3%±7.7%, 31.5%±4.9% vs 34.7%±5.8%, 1.05±0.24 vs 1.18±0.32; group B: 49.2%±7.0% vs 62.0%±14.0%,29.2%±5.5% vs 42.2%±7.3%, 1.07±0.26 vs 1.39±0.42; all P<0.05), while the level of CD8(+)was lower than before treatment (group A: 30.4%±5.4% vs 24.5%±4.8%; group B: 29.5%±4.1% vs 21.1%±4.5%; all P<0.05). The CD3(+), CD4(+), and CD4(+)/CD8(+) levels in group A were lower than those in group B (P<0.05), while CD8(+)level was higher than in group B (P<0.05). After 2 cycles of treatment, the VEGF levels in the two groups were lower than before treatment (group A: (423±85) vs (352±64) ng/L; group B: (404±114) vs (296±66) ng/L; P<0.05), and the VEGF level in group A was higher than that in group B (P<0.05). The 1-year survival rates of groups A and B were 54.9% and 77.9%, and the 2-year survival rates were 17.2% and 41.7% (Log rank χ(2)=4.750, P=0.029). Conclusion: DEB-BACE combined with systemic chemotherapy is superior to systemic chemotherapy in the treatment of unresectable lung squamous cell carcinoma. It can reduce toxic and side effects, improve immune function and prolong survival time, which is worthy of clinical application.

Abstract
OBJECTIVE To evaluate the effects of water body environments on the microbial community of Oncomelania hupensis snails in marshlands of the eastern Dongting Lake where natural extinction of O. hupensis snails are found, so as to explore the correlation between the natural extinction of O. hupensis snails and the microbial community in snails. METHODS Snails were caged water bodies in the Qianliang Lake marshland (Qianliang Lake regions) where natural extinction of snails was found and in the Junshan Park marshland (Junshan Park regions) in the eastern Dongting Lake for 30 days, and then all snails were collected and identified for survival or death. DNA sequencing of the fungi and bacteria was performed in snails before and after immersion in waters, and the biodiversity and abundance were analyzed. RESULTS The survival rates of O. hupensis snails were 28.0% (70/250) and 64.8% (162/250) in Qianliang Lake regions and Junshan Park regions 30 days after immersion in waters, respectively (χ2 = 81.365, P < 0.01). The number of the fungal community and the biodiversity of the bacterial community were both greater in snails caged in Qianliang Lake regions post-immersion than pre-immersion, and there was a significant difference in the structure of the fungal and bacterial communities. The microbial community with a significant difference included Flavobacteriaceae,which was harmful to O. hupensis snails. CONCLUSIONS The water body environment affects the composition of the microbial community in O. hupensis snails in marshlands with natural snail distinction around the eastern Dongting Lake; however, further studies are required to investigate whether the natural distinction of snails is caused by water body environments-induced changes of the microbial spectrum in O. hupensis snails.

Abstract
Polycrystalline Co2Ti1-xCrxO4 (0 ≤ x ≤ 0.2) inverse spinel ceramics have been synthesized via a sol-gel technique. The dc magnetization measurement in the field-cooled mode shows that negative magnetization could be observed until x reaches 0.2. The exchange constants are calculated using the ferrimagnetic Curie-Weiss fitting and the mean-field theory. This reveals that the strength of the inter sublattice magnetic interaction presents a non-monotonic trend with the increase in Cr content and reaches the minimum at x = 0.1, giving rise to the highest compensation temperature in the x = 0.1 sample. The applicability of the x = 0.1 sample is investigated in light of two prominent magnetic effects: (i) the stable magnetic switching effect indicates the potential applications in magnetic switching and data storage and (ii) the coexistence of normal and inverse magnetocaloric effects suggests a potential application in a constant temperature bath at 54 K.

Abstract
Pigment epithelium-derived factor (PEDF) is an oncogene found in various types of cancers. However, how PEDF affects the development of human esophageal squamous cell carcinoma (ESCC) is unknown. This study investigates the role of PEDF in ESCC cell proliferation, migration, and cell cycle both in vitro and in vivo. The PEDF expression was examined in patient tumor samples and ESCC cell lines. Short hairpin RNA technology was used to inhibit the PEDF expression in ESCC EC9706 and KYSE150 cells. In vitro cell proliferation and migration assays were performed. The effects of PEDF on tumor growth and progression were examined in vivo in murine subcutaneous xenograft tumor models. It was found that PEDF was overexpressed in esophageal cancer cells and patient tumor tissues compared to normal control samples. PEDF enhanced cell cycle progression and inhibited cell apoptosis. Knock down of PEDF inhibited esophageal cell proliferation and migration in vitro. Moreover, Inhibition of PEDF significantly reduced tumor growth and tumor size in vivo. These results indicate that PEDF induce tumorigenesis in ESCC and can be a potential therapeutic target for cancer treatment.

Abstract
In this retrospective study, we compared the efficacy and safety of mechanical adjuvants in mucosal-sparing, mechanical endoscopic dacryocystorhinostomy (MMED) for primary acquired nasolacrimal duct obstruction (PANDO). 116 adult patients (90 female) aged 61 ± 11 received one of the following after MMED without topical mitomycin: no stenting or packing (group 1, n = 25), 1-week ostium packing by ribbon gauze (group 2, n = 29) or non-medicated absorbable gelatin sponge (group 3, n = 25), 8-week bicanalicular stenting (group 4, n = 28). 104 patients(92%) provided 12-month outcomes. Number of patients, age, gender, surgeon, and osteotomy size were comparable among groups (p = 0.4-0.9). Marginal significance was found in anatomical (group 1:80%, group 2:96.6%, group 3:96%, group 4:96.4%, p = 0.05) but not functional success (group 1:85%, group 2:85.7%, group 3:83.3%, group 4:88.9%, p = 0.75) at postoperative 12-month. Patients receiving any packing or stenting achieved better anatomical (96% versus 80%, p = 0.015) but not functional success (85% versus 86%, p = 0.90) compared to those receiving none. More patients receiving stenting developed postoperative granuloma than those who did not (87% versus 63%, p = 0.04). 1-week ostium packing was found to be as effective as 8-week bicanalicular intubation in improving anatomical outcome after MMED for PANDO. Functional outcome, however, did not differ among patients receiving mechanical adjuvant or not.

Abstract
Objective: To evaluate the clinical efficacy of endovascular treatment for non-thrombotic right iliac vein compression syndrome with intravascular ultrasound. Methods: The clinical data of 40 patients with non-thrombotic right iliac vein compression syndromereceiving intravascular ultrasound-assisted balloon dilatation combined with stent implantation from January 2012 to December 2018 were retrospectively analyzed. There were 32 males and 8 females, the average age of whom was 63 (46-81) years old. The patients were classified according to the CEAP (Clinical-Etiology- Anatomy-Pathophysiology) classification: 7 cases as C3, 18 as C4, 10 as C5 and 5 as C6. All patients underwent percutaneous right femoral vein puncture, intravascular ultrasound, and balloon dilatation combined with stentimplantation in the right iliac vein lesion location. Results: The success rate of clinical operations was 100%. There were no serious complications during the perioperative period. All patients were followed up for 4-58 months. During the follow-up period, the relief rate of limb edema was 88.6% (31/35), the pain relief rate was 86.7%(13/15), and the healing rate of ulcers was 100% (6/6). After the stent implantation, the endovascular area of the compression site was significantly enlarged (34.5mm(2)± 11.1mm(2)vs129.8 mm(2)±17.2 mm(2), P<0.001). The follow-up of color Doppler and/or anterograde angiography for deep veins of lower limb with digital subtraction angiography showed that the blood flow in the stentsweres mooth in all patients. Three cases were observed that the intimal hyperplasia led to mild in-stent restenosis, no obvious in stent restenosis (>50%). The abdominal X-ray plain film showed no obvious displacement and fracture of the stents. The venous clinical severity score (VCSS) was statistically significant (13.0±2.4 vs 6.2±2.0, P<0.001). The statistical results of short-form health surver SF-36 showed that the scores of life quality in all dimensions of the affected limb were significantly improved after operation (P=0.000). Conclusion: Intravascular ultrasound-assisted balloon dilatation combined with stent implantation is not only a safe and effective treatment for non-thrombotic right iliac vein compression syndrome, but also has a good mid-term patency rate.

Abstract
Half-metallic materials have gained a lot of attention because of their unique properties and applications in spintronic devices. Despite the fact that these materials have been studied by several research groups there are very limited studies on their heterostructure (HS) systems. In the current study we have investigated the electronic and magnetic properties of (LaAlO3)6.5/(SrTiO3)2.5(111) HS using density functional theory (DFT) calculations. We demonstrate that the system exhibits a 100% spin-polarized two-dimensional electron gas (2DEG) which is extremely confined to the Ti 3d orbitals of the SrTiO3 layers. In particular, this system can keep its half-metallic properties under different in-plane strains from -3 to 2%. This property proves that this material has relatively stable half-metallic properties. In addition, the conducting and magnetic ground states of the system can also be tailored by changing in-plane strain and interfacial cation intermixing of La and Sr (Sr ⇔ La intermixing). By increasing the in-plane lattice parameters, this system has the ability to evolve from a nonmagnetic to a ferromagnetic metal and then to a half-metal and by further increasing the in-plane lattice parameter it becomes a ferromagnetic insulator. Sr ⇔ La intermixing can destroy the original half-metallic properties and the system exhibits an AFM Mott-type insulator phase. Our results demonstrate that the system has high potential for application in the field of spintronics, and opens the prospect of using LaAlO3/SrTiO3(111) HSs to explore quantum phase transitions.

Abstract
AIM To investigate the accuracy of ultrasonography in the diagnosis of persistent sciatic artery (PSA) compared to computed tomography angiography (CTA). MATERIALS AND METHODS From May 2002 to Dec 2018, 61 consecutive patients seen at Shandong Medical Imaging Research Institute with a clinical suspicion of PSA were included. Ultrasonography was used to assess the abdominal and lower-limb arteries. The main sonographic criteria for a positive diagnosis were the visualisation of PSA, the enlarged internal iliac artery, and abnormality of common femoral artery and superficial femoral artery. These data were compared with CTA findings. Kappa statistics was applied to determine the level of agreement. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography as a diagnostic method were assessed. RESULTS Ultrasonography findings were positive in 16 of 61 patients with a clinical suspicion of PSA. The diagnosis was confirmed by CTA in 17 patients. There was one false-positive result and two false-negative results at ultrasonography. The kappa value was 0.875. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography were 88.2%, 97.7%, 93.8%, 95.6%, 95.1% and 0.859, respectively. CONCLUSIONS Ultrasonography could be a reliable, accurate, and non-invasive diagnostic imaging method in the diagnosis of patients with suspected PSA.

Abstract
Objective: To investigate China statistics of extracorporeal life support (ECLS) in 2018. Methods: The statistics data was collected by provincial coordinators assigned by Chinese Society of Extracorporeal Life Support (CSECLS) in 2019, including cases, centers, indications, and in-hospital survival rate. Results: Three thousand nine hundred and twenty-three cases were reported by 260 ECLS centers. There were an increase of 38.8% in extracorporeal membrane oxygenation (ECMO) cases and an increase of 11.6% in ECMO centers compared with that in 2017 (2 826 cases and 233 centers). Adult, pediatric, and neonatal patients accounted for 88.0%, 9.7%, and 2.3% of total cases, respectively. Centers with more than 20 ECMO cases per year had favorable in-hospital survival rate compared with those less than 20 cases (49.1% vs 44.0%, P=0.005). ECMO cases (r=0.71, P<0.001) and centers (r=0.81, P<0.001) were both associated with regional gross domestic product. Conclusions: There was a growth in ECLS cases, centers, and center scale in China within 2018. The majority of ECLS cases and centers were in developed regions. The ECLS indications, and in-hospital mortality in China were in accordance with that in the Extracorporeal Life Support Organization registry gradually. Large-scale ECLS centers had favorable patient outcomes. The development of ECLS still has tremendous potential in China, especially for pediatric and neonatal patients.
