Abstract
Objective: To investigate the effect of serine/arginine-rich splicing factor 2 (SRSF2) on ferroptosis and its possible mechanism in glioblastoma cells. Methods: The online database of gene expression profiling interactive analysis 2 (GEPIA 2) and Chinese Glioma Genome Atlas were used to analyze the expression of SRSF2 in glioblastoma tissue and its association with patients prognosis. To validate the findings of the online databases, the pathological sections of glioblastoma and non-tumor brain tissues from Tianjin Medical University General Hospital, Tianjin, China were collected and analyzed by using immunohistochemistry. Silencing SRSF2 gene expression in glioblastoma cells by siRNA was analyzed with Western blot. The proliferation index was detected by using CCK8 assay. The rescued experiment was conducted by using expression plasmid of pcDNA3.1(+)-SRSF2. The activity of ferroptosis was assessed by using the levels of iron ions and malondialdehyde in glioblastoma cells and the changes in the ratio of glutathione to oxidized glutathione. The changes of gene expression and differential pre-mRNA alternative splicing (PMAS) induced by SRSF2 were monitored by using the third-generation sequencing technology analysis, namely Oxford nanopore technologies (ONT) sequencing analysis. Results: SRSF2 expression was higher in glioblastoma tissues than non-tumor brain tissues. Immunohistochemistry also showed a positive rate of 88.48%±4.60% in glioblastoma tissue which was much higher than the 9.97%±4.57% in non-tumor brain tissue. The expression of SRSF2 was inversely correlated with overall and disease-free disease survivals (P<0.01). The proliferation index of glioblastoma cells was significantly reduced by silencing with SRSF2 siRNA (P<0.01) and could be reversed with transfection of exogenous SRSF2. The levels of intracellulariron ions and malondialdehyde increased (P<0.05), but the glutathione/oxidized glutathione ratio and the expression of key proteins in the glutathione pathway remained unchanged (P>0.05). ONT sequencing results showed that silencing SRSF2 in glioblastoma cells could induce a significant alternative 3' splice site change on ferroptosis suppressor protein 1 (FSP1). Conclusion: SRSF2 inhibits the ferroptosis in glioblastoma cells and promotes their proliferation, which may be achieved by regulating FSP1 PMAS.

Abstract
Lepiota brunneoincarnata is a highly toxic mushroom species known to cause acute liver failure. However, there are limited reports investigating L. brunneoincarnata causing acute hepatic and renal damage. The present article reports 2 cases of L. brunneoincarnata poisoning in a mother and son from Chuxiong City, Yunnan Province, China. Both patients presented with gastrointestinal symptoms approximately 8-9 h after ingesting the suspect mushrooms and sought medical attention 27-28 h post-ingestion, both exhibiting acute hepatic and kidney injuries. Morphological and molecular biology studies confirmed the species of the mushrooms as L. brunneoincarnata. Liquid chromatography-tandem mass spectrometry analysis revealed mean fresh-weight concentrations of 123.5 μg/g α-amanitin and 45.7 μg/g β-amanitin in the mushrooms. The patients underwent standard treatments, including multiple-dose activated charcoal, oral silibinin capsules, N-acetylcysteine, penicillin G, hemoperfusion, and plasma exchange. One patient recovered completely and was discharged after 16 days of hospitalization. The other patient exhibited gradual improvement in liver and renal function; however, renal function deteriorated 9 days after ingestion, and the patient declined renal replacement therapy and returned home 14 days post-ingestion. The patient was then re-hospitalized due to oliguria and edema in both lower extremities. Renal biopsy revealed acute tubular necrosis, inflammatory cell infiltration, minor glomerular capsular fibrosis, loss of microvilli in the renal tubular epithelial cells, and interstitial edema. The patient underwent 2 rounds of continuous renal replacement therapy, which eventually resulted in improvement, and was discharged 31 days after mushroom consumption. It is noteworthy that this patient had already progressed to chronic kidney insufficiency 11 months after intoxication.

Abstract
Objective: To conduct a nationwide physician survey to better understand clinicians' disease awareness, treatment patterns, and experience of Waldenström macroglobulinemia (WM) in China. Methods: This cross-sectional study was conducted from February 2022 to July 2022 by recruiting clinicians with WM treatment experience from hematology, hematology-oncology, and oncology departments throughout China. Quantitative surveys were designed based on the qualitative interviews. Results: The study included 415 clinicians from 219 hospitals spread across thirty-three cities and twenty-two provinces. As for diagnosis, the laboratory tests prescribed by physicians for suspected WM patients were relatively consistent (92% -99% recommendation for laboratory, 79% -95% recommendation for pathology, 96% recommendation for gene testing, and 63% -83% recommendation for imaging examination). However, from a physician's perspective, there was 22% misdiagnosis occurred in clinical practice. The rate of misdiagnosis was higher in lower-level hospitals than in tertiary grade A hospitals (29% vs 21%, P<0.001). The main reasons for misdiagnosis were that WM was easily confused with other diseases, and physicians lacked the necessary knowledge to make an accurate diagnosis. In terms of gene testing in clinical practice, 96% of participating physicians believed that WM patients would require gene testing for MYD88 and CXCR4 mutations because the results of gene testing would aid in confirming diagnosis and treatment options. In terms of treatment, 55% of physicians thought that the most important goal was to achieve remission, while 54% and 51% of physicians wanted to improve laboratory and/or examination results and extend overall survival time, respectively. Among patients with treatment indications, physicians estimated that approximately 21% of them refused to receive treatment, mainly owing to a lack of affordable care and disease awareness. When selecting the most appropriate treatment regimens, physicians would consider patient affordability (63% ), comorbidity (61% ), and risk level (54% ). Regimens containing Bruton tyrosine kinase inhibitor (BTKi) were most widely recommended for both treatment-naïve and relapsed/refractory patients (94% for all patients, 95% for treatment-naïve patients, and 75% for relapsed/refractory patients), and most physicians recommended Ibrutinib (84% ). For those patients who received treatment, physicians reported that approximately 23% of patients did not comply with the treatment regimen due to a lack of affordability and disease awareness. Furthermore, 66% of physicians believe that in the future, increasing disease awareness and improving diagnosis rates is critical. Conclusions: This study is the first national physician survey of WM conducted in China. It systematically describes the issues that exist in WM diagnosis and treatment in China, such as a high rate of misdiagnosis, limited access to gene testing and new drugs, and poor patient adherence to treatment. Chinese doctors believe that improving doctors' and patients' understanding of WM is one of the most urgent issues that must be addressed right now.

Abstract
In the surgical treatment of hemorrhoids, rectal prolapse, rectal cancer, anal fissures, or anal fistulas, inadvertent damage to the nerves or muscles responsible for bowel control may potentially lead to varying degrees of fecal incontinence (FI). Surgeons need to conduct preoperative assessments based on the patient's individual condition to select an appropriate surgical plan, aiming to minimize the incidence of postoperative FI and improve the patient's postoperative quality of life as much as possible while effectively treating the disease. Additionally, the proficiency of the surgeon's skills, appropriate preoperative dietary adjustments for the patient, regular bowel habits, and exercises targeting the pelvic floor muscles all contribute to reducing the incidence of postoperative FI in patients. For patients who have already developed FI after surgery, on the basis of suitable diet, regular bowel habits, and medication, clinical practitioners can adopt such methods as biofeedback, pelvic floor muscle exercise, sacral nerve stimulation, percutaneous tibial nerve stimulation, acupuncture, injectable bulking agents, anal or vaginal inserts, transanal irrigation, surgical interventions, psychological support, etc., to individualized treatment for patients' conditions. This article, combining the literature, summarizes the current status of common diseases that may lead to postoperative FI. It elaborates on strategies for the prevention and treatment of postoperative FI, aiming to serve as a reference for peers in the field.

Abstract
Objective: To compare the outcomes between iliac crest and accessory navicular as different bone grafts in the Cotton osteotomy in the treatment of pediatric flexible flatfoot deformity. Methods: A retrospective cohort study. The clinical data of pediatric flexible flatfoot patients with symptomatic accessory navicular received operations from July 2018 to March 2022 in Beijing Tongren Hospital were retrospectively analyzed. All the patients were treated with Cotton osteotomy. According to the different sources of bone grafting in Cotton osteotomy, the patients were divided into iliac crest group and accessory navicular group. There were 12 patients (19 feet) in iliac crest group, including 9 males and 3 females with a median age M(Q1, Q3) of 11(11, 12) years and were followed-up for 36(6, 48) months. There were 9 patients (16 feet) in accessory navicular group, including 6 males and 3 females, with a median age M(Q1, Q3) of 11(11, 11) years and were followed-up for 12(6, 17) months. Radiographic evaluations were reviewed and compared between the two groups before surgical treatment and at final follow-up, included talo-1st metatarsal angle (T1MT), talonavicular coverage angle (TNCA), talocalcaneal angle (TCA) in weight bearing anteroposterior view, and Meary angle, calcaneal Pitch angle, Kite angle, cuneiform articular angle (CAA) in weight bearing lateral view, and hindfoot alignment angle (HAA) in calcaneal long axial view. Functional scores included American Orthopedic Foot and Ankle Society (AOFAS), visual analog scale (VAS), and Maryland scores were recorded and compared before and after the operation. The complications were also recorded. Results: Total of 21 patients were successfully followed in this study. The radiographic measurements in the two groups, such as T1MT, TNCA, Meary angle, Pitch angle, Kite angle, CAA, HAA, were all significantly improved at the last follow-up when compared with those before the surgery (all P<0.05); and the AOFAS, VAS, Maryland scores in both groups were all improved after the surgery (all P<0.05). There was a significant difference in CAA alteration (∆CAA) after the operation between the two groups, the ∆CAA in iliac crest group and the accessory navicular group was 6.0°±2.6° and 4.3°±1.3°, respectively (P=0.017). There was no significant differences in the improvement of other radiographic measurements between the two groups (all P>0.05). All the patients had a successful bone union. Two patients had donor site pain in the iliac crest group and were treated conservatively. Conclusion: Compared with iliac crest bone graft, accessory navicular bone graft could achieve comparable outcomes in radiographic measurements and functional scores in the treatment of pediatric flexible flatfoot with accessory navicular pain.

Abstract
Objective: To investigate the effect of 1-acyl-sn-glycerol-3-phosphate acyltransferaseδ (APGAT4) on the growth and lenvatinib resistance of hepatocellular carcinoma (HCC), and provide novel targets for HCC treatment. Methods: Using the bioinformatics methods to screen out upregulated genes in lenvatinib resistant cell lines from GEO dataset and survival related genes from TCGA dataset. Immumohistochemical staining was used to detect the expression AGPAT4 in HCC tissues, and its correlation with patients' survival. CCK8, EdU, cell cycle, and cell apoptosis assays were used to investigate the impact of role AGPAT4 on the proliferation and lenvatinib reistance of HCC cells. AGPAT4 stable knockdown cell line and subcutaneous nude mouse model were established to test the therapeutic effects of Lenvatinib. Analysis of variance was used to compare the differences between data sets. Results: APGAT4 was the common factor that predicted poor survival and Lenvatinib resistance. The mRNA and protein levels of APGAT4 were significantly upregulated in HCC tissues compared to the para-tumor tissues (P < 0.05). Using siRNA could significantly knocked down the mRNA and protein expression of APGAT4 in HCC cell lines Hep3B and HCCLM3. Compared with the control group, the proliferation ability of HCC cell lines (Hep3B and HCCLM3) in APGAT4 knockdown group was significantly inhibited, and the cell cycle was arrested in G2/M phase (P < 0.05). In addition, compared to the control group, HCC cell lines (Hep3B and HCCLM3) in APGAT4 knockdown group showed significant decrease in the Lenvatinib half maximal inhibitory concentration, and were more sensitive to lenvatinib-induced apoptosis (P < 0.05). In HCC subcutaneous nude mouse model, compared to the control group, the growth of tumor in APGAT4 knockdown group was significantly suppressed, and more apoptosis cells were induced (P < 0.05). Conclusion: APGAT4 promotes the growth and Lenvatinib resistance of HCC, which is a potential target for HCC treatment. Targeting APGAT4 treatment is conducive to inhibit the growth and Lenvatinib resistance of HCC.

Abstract
Objective: To investigate the wearing of masks and the knowledge of masks among high-risk positions for overseas import and pollution transmission. Methods: From May 14 to 17, 2022, a convenient sampling method was used to conduct an online survey among 963 workers in high-risk positions for overseas import and pollution transmission in Beijing. The behaviors of individual use and wearing masks, the distribution and supervision of the unit, the knowledge of personal mask protection and the subjective feelings of wearing masks were analyzed. The χ(2) test and logistic regression model were used to analyze the influencing factors of the correct selection of masks. Results: The majority of the workers in high-risk positions for overseas import and pollution transmission were male (86.0%, 828/963), age concentration in 18-44 years old (68.2%, 657/963), and the majority of them had college or bachelor degrees (49.4%, 476/963). 79.4%(765/963) of the workers chose the right type of masks, female, 45-59 years old and high school education or above were the risk factors for correct selection of masks (P <0.05). Workers had good behaviors such as wearing/removing masks, but only 10.5% (101/963) could correctly rank the protective effect of different masks. 98.4% (948/963) of the workers believed that their work units had provided masks to their employees, and 99.1% (954/963) and 98.2%(946/963) of them had organized training and supervision on the use of masks, respectively. 47.4%(456/963) of the workers were uncomfortable while wearing masks. Conclusion: The overall selection and use of masks among occupational groups in high-risk positions for overseas import and pollution transmission in China need to be further standardized. It is necessary to strengthen supervision and inspection on the use of masks among occupational groups, and take improvement measures to improve the comfort of wearing masks.

Abstract
The soaring prevalence of obesity and its complications presents a significant health care burden, and there is currently a lack of effective and sustainable treatment methods. Time-restricted eating (TRE) is a specific intermittent fasting (IF) protocol involving consistent fasting and eating periods within a 24-hour cycle. Time-restricted eating can restore robust circadian rhythms and improve metabolic health, providing an emerging dietary strategy for the prevention and treatment of obesity and related metabolic diseases. Previous TRE trials laid the groundwork, and indicate a need for further clinical research including large-scale controlled trials to determine TRE efficacy and the mechanisms by which it may affect humans.

Abstract
Traumatic scar can not only exert influence on appearance and function of patients, but also affect psychological health status and life quality of patients to varying degrees. At present, scholars have confirmed from basic research that mechanical tension promotes the proliferation of inflammatory cells, fibroblasts, and other cells, as well as angiogenesis and epithelialization through a variety of mechanical conduction pathways and plays an important role in the formation of hypertrophic scar. Clinical studies have confirmed that surgical methods and adjuvant treatment to reduce the mechanical tension on wound can promote wound healing and inhibit hyperplasia of scar. This article summarizes the mechanism of hypertrophic scar formation, and surgical methods and adjunct means of reducing mechanical tension in traumatic wounds, aiming to provide a reference for reducing formation of hypertrophic scar in clinics.

Abstract
Objective: To observe the therapeutic effect of terlipressin on refractory ascites (RA) in cirrhosis, and its role and impact on acute kidney injury (AKI). Methods: A non-randomized controlled clinical trial data of 111 hospitalized cases of liver cirrhosis accompanied with RA was collected from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Zhongshan Hospital of Hubei Province, The First Affiliated Hospital of Zhengzhou University, The First Affiliated Hospital of Medical School of Zhejiang University, and People's Hospital of Pudong New Area of Shanghai between March 2015 and March 2017. 26 cases of conventional treatment group (control group) were divided into two subgroups: RA without AKI (RA-NAKI) and RA with AKI (RA-AKI), and each subgroup consisted 13 cases. Patients with bacterial infection were treated with diuretics, albumin supplementation and antibiotics. 85 cases were presented in terlipressin combined treatment group, of which 27 cases were of RA-NAKI and 58 cases were of RA-AKI. Control group was injected terlipressin 1mg of intravenous drip or static push (once q6 h ~ 12 h) for more than 5 days. The treatment duration lasted for 2 weeks with 4 weeks of follow-up. Body weight, 24-hour urine volume, abdominal circumference, mean arterial pressure (MAP), liver and kidney function, anterior hepatic ascites, deepest point of ascites, and ultrasonographic detection of ascites in supine position before treatment, one and two weeks after treatment and 4 weeks after follow-up were compared. Count data were tested by χ (2). Samples of four groups at baseline were compared. One-way analysis of variance was used for normal distribution data and Kruskal-Wallis H test for non-normal distribution data. Repeated measures analysis of variance was used to compare the difference in efficacy between different time points before and after treatment in the group. The LSD method of one-way ANOVA was used to compare the two groups. A t-test of independent samples was used to compare the efficacy of different time series between the two groups. Mann-Whitney rank- sum test was used to compare the data of non-normal distribution between the two groups. Results: (1) Baseline data were compared among 4 subgroups of terlipressin RA-NAKI and control RA-AKI. Control group age was higher than that of terlipressin group, and the serum creatinine (SCr) of the RA-AKI group was higher than RA-NAKI group, and there was no significant difference in the rest of the baseline data and the combined medication (P > 0.05). (2) An intra-group comparison between control and trelipressin before and after treatment showed that all patients had lower body mass, abdominal circumference and deepest ascites, and higher serum albumin (P < 0.05). 24-hour urine volume and MAP was significantly increased in the terlipressin group, while the pre-ascites, SCr and child Turcotte Pugh (CTP) scores were decreased. Body weight, abdominal circumference, pre-ascites, and deepest ascites of the terlipressin group were decreased, while MAP was increased during the treatment and follow-up periods. The differences were statistically significant when compared with the control group at the same time (P < 0.05). There was a statistically significant difference in the increase of 24-h urine volume in the terlipressin group compared with the control group (P < 0.05). The decrease in SCr and CTP in the terlipressin group after 2 weeks of treatment and 4 weeks of follow-up was statistically significant compared with the control group (P < 0.05). (3) Among the two subgroups of RA-AKI and RA-NAKI in the terlipressin group, the baseline SCr value of the former was higher than that of the latter. After treatment, the body weight, abdominal circumference, pre-ascites, deepest ascites and CTP scores were decreased. In the RA-AKI group, 24-hour urine volume, MAP, SCr and serum albumin concentration were significantly increased. The difference between the two subgroups before and after treatment was compared, and the body weight of RA-AKI group at 1, 2 weeks of treatment and 4 weeks of follow-up was significantly lower than RA-NAKI group, which were (- 2.3 ± 0.2 vs. - 1.5 ± 0.2) kg, (- 4.1 ± 0.2 vs. - 2.6 ± 0.2) kg, (- 4.2 ± 0.3 vs. - 2.4 ± 0.3) kg, respectively. RA-NAKI group urine volume was significantly increased at 2 weeks of treatment and 4 weeks of follow-up, which was (468 ± 42 vs. 110 ± 131) ml, (272 ± 34 ml vs. 11 ± 112) ml, respectively. SCr reduction (18.3 ± 4.7 vs. 0.9 ± 2.4) µmol/l at 4 weeks of follow-up was apparent in RA-NAKI group, and the difference was statistically significant (P < 0.05). Conclusion: Addition of terlipressin to conventional treatment may significantly increase MAP, 24-h urine volume, improve renal function and promote ascites resolution in patients with refractory cirrhotic ascites. Moreover, its combination effect is more obvious in AKI patients, and adverse reactions are mild.

Abstract
Objective: To analyze the relationship between the severity of esophageal acid reflux and esophageal motility, esophageal mucosal injury and morphological anatomy of gastroesophageal junction (GEJ) in patients with gastroesophageal reflux disease (GERD). Methods: The clinicaldata of GERD patients who underwent 24 h pH-impedance monitoring, gastroscopy and high-resolution manometry (HRM) from January 2016 to January 2019 in the Gastroesophageal Surgery Department of PLA Rocket Force Characteristic Medical Center were retrospectively analyzed. The patients were divided into non-pathological acid reflux group, mild pathological acid reflux group and moderate to severe pathological acid reflux group according to the DeMeester score. The gender and age of each group were matched, with 60 cases in each group. Statistical analysiswas performed to analyze thedifferences in upper esophageal sphincter pressure, lower esophageal sphincter pressure (LES), LES length, length of ventral LES, percentage of ineffective swallowing, esophagitis, Hill grade of GEJ, and hiatus hernia (HH) in each group. The comparison and correlation analysis are also carried out between the groups. Results: The male-female ratio was 33/27, and the age was (57±13) years in each group. Non-parametric analysis showed that the LES pressure and the length of the ventral LES decreased with the severity of acid reflux, and there was a statistical difference (P= 0.033, P=0.015). The detection rate of HH by HRM increased significantly (χ(2)=0.001) as well. Esophagitis score increased with the severity of acid reflux and there was statistical difference (P<0.001).The detection rate of esophagitis increased significantly (χ(2)<0.001) as well. Hill grading score of GEJ increased with the severity of acid reflux, and there was statistical difference (P<0.001).The detection rate of HH by endoscopy increased significantly (χ(2)<0.001) as well. The correlation between DeMeester score and LES pressure, length of ventral LES, percentage of ineffective swallowing, esophagitis score, and Hill grade score were statistically significant (P<0.05). Conclusions: The esophageal low motility (such as low LES pressure) and anatomical abnormalities (abdominal esophageal shortening, GEJ flabbiness, and even HH formation) of the GEJ regionare significantly associated with the severity of acid reflux. These factors may be important causes of increased acid reflux. In addition, the aggravation of acid reflux can also increase the incidence and severity of esophagitis.

Abstract
Objective: To analyze the antimicrobial resistance and multilocus sequence typing (MLST) results of extended-spectrum β-lactamase (ESBLs)-producing Escherichia coli in rural residents in villages with pig breeding farms in a county of Shandong province. Methods: Antimicrobial susceptibility testing was performed with agar dilution method by using 360 ESBLs-producing E. coli strains from fresh stool samples of rural residents in villages with pig breeding farms in a county of Shandong. PCR was conducted to amplify the CTX-M, TEM, SHV genes and capillary electrophoresis was used to screen positive strains in July, 2016. MLST was performed for molecular typing analysis, and eBURST v3.0 software was used for cluster analysis. Results: Among 360 strains of ESBLs-producing E. coli, the resistance rates to cefotaxime, tetracycline, trimethoprim-sulfamethoxazole and florfenicol were 100.0% (360/360), 82.2% (296/360), 81.1% (292/360) and 80.3% (289/360), respectively. The positive rate of CTX-M gene was 99.2% (357/360), in which the positive rate of CTX-M-9 was 35.6% (128/360) and the positive rate of CTX-M-1 was 24.4% (88/360). The positive rate of TEM gene was 26.9% (97/360). A total of 132 STs were identified through MLST. The predominant ST was ST10, accounting for 12.5% (45/360). Cluster analysis showed that CC10 was the most important clone group, including 39 ST clones, involving 148 strains (41.1%). Conclusions: The drug resistances of ESBLs-producing E. coli to cefotaxime, tetracycline, trimethoprim-sulfamethoxazole and flurfenicol are serious in this rural area. There is a small-scale clustering of CC10 and transmission mode from animals to humans might exist.

Abstract
Recently published studies on the association between depression and hip fracture (HF) are inconsistent. Therefore, we performed this meta-analysis with the main aim to clarify the association between depression and HF, and also to identify possible susceptible groups. Relevant literature published until February 2019 was obtained and screened according to established inclusion criteria. Two researchers independently processed quality assessment and data extraction prior to the meta-analysis. Pooled hazard ratios (HRs) with 95%CI (confidence intervals) were calculated. To explore the sources of heterogeneity, subgroup analyses were performed based on study design, study region, NOS scores, follow-up duration, diagnostic criteria, sex, national income level, and adjustments (bone mineral density (BMD), antidepressant, calcium intake, and smoking). Ten studies with 13 estimates, involving 375,438 participants and 4576 HFs, were included. It was found that patients with depression had a higher risk of HF than non-depressed patients (HR = 1.21; 95%CI 1.11-1.31). Sensitivity analysis results show that the association is relatively stable. The studies that were not adjusted for confounders (e.g., antidepressant, BMD, calcium intake, and smoking) had higher overall HR compared to the studies that adjusted for the corresponding confounding factors. HFs are more likely to occur in European and male depression patients. This meta-analysis provided evidence of a modest positive association between depression and the risk of HFs, and the association is stronger in European and male patients. Implementation of practical measures to prevent and treat depression is of great public health significance.

Abstract
The most frequently reported fatal Lepiota ingestions are due to L. brunneoincarnata. We present a case of L. brunneoincarnata poisoning with endoscopic nasobiliary drainage known to be the first in China. The patient suffered gastrointestinal symptoms 9 h post ingestion of mushrooms. The patient was hospitalized 4 days after eating the mushrooms with jaundice. The peak ALT, AST, APTT, TBIL and DBIL values of the patient were as follow: ALT, 2980 U/L (day 4 post ingestion); AST, 1910 U/L (day 4 post ingestion); APTT, 92.8 seconds (day 8 post ingestion), TBIL, 136 μmol/L (day 10 post ingestion), DBIL 74 μmol/L (day 10 post ingestion). UPLC-ESI-MS/MS was used to detect the peptide toxins in the mushroom and biological samples from the patient. We calculated that the patient may have ingested a total of 29.05 mg amatoxin from 300 g mushrooms, consisting of 19.91 mg α-amanitin, 9.1 mg β-amanitin, and 0.044 mg γ-amanitin. Amatoxins could be detected in bile even on day 6 after ingestion of L. brunneoincarnata. With rehydration, endoscopic nasobiliary drainage and intravenous infusion of Legalon SIL, the patient recovered after serious hepatotoxicity developed.

Abstract
Objective: To analyze the epidemic characteristics of acute occupational poisoning events in order to state the regularity of outbreak and provide scientific evidences of prevention and control measure in China. Methods: According to the report information from the Management Information System of Public Health Emergency, we analyzed acute occupational poisoning events time distribution, regional distribution, toxicant variety, route of exposure and events detection from 2006 to 2016. Results: The total number of acute occupational poisoning events reported in 26 provinces of China from 2006 to 2016 was 337, causing 2 399 people poisoned, and the fatality rate was 18.09%. Majority of them were higher grade events and the top three provinces of acute occupational poisoning events were Shanghai, Anhui, Shandong. Inhalation is the main cause of poisoning. The acute occupational poisoning events for carrying out poison dectection were accounted for 56.68%. Conclusion: Acute occupational poisoning events in China is reducing year by year, But fatality rate is not decrease. So the country should increase the supervision and management of safety in production, strengthen the safety education of employees and coordination mechanism among different departments.

Abstract
Amatoxin poisoning induces delayed-onset acute liver failure, which are responsible for more than 90% of deaths in mushroom poisoning. It has been postulated from animal and human studies that biliary drainage interrupting enterohepatic amatoxin circulation may affect amatoxin poisoning. Dogs were randomly divided into four groups of six animals each. In 20 mg/kg and 60 mg/kg with biliary drainage groups, after accepting bile drainage operation, beagles were fed Amanita exitialis powder (20 or 60 mg/kg) in starch capsules. In control and bile drainage groups, the beagle dogs were fed with empty capsules. They were assessed for toxicity signs, biochemical and pathological changes, and peptide toxins in plasma, urine and bile. The data were directly compared with those from our published studies on Amanita exitialis-exposed beagles without biliary drainage. Amatoxins were rapidly absorbed and eliminated from plasma after Amanita exitialis ingestion. Amatoxins in 0–1-day urine accounted for more than 90% of the total urine excretion, and amatoxins in bile accounted for less than 20% of the total urine and bile excretion. The dogs with biliary drainage showed less severe toxicity signs and biochemical and pathological changes and much lower internal exposure than dogs without biliary drainage. Biliary drainage caused a more than 70% reduction in intestinal amatoxin absorption and could reduce amatoxin absorption from the gastrointestinal tract.

Abstract
Atmospheric ammonia in animal housing is reported to have adverse effects on livestock performance and animal health. Previous experiments have found that 75 ppm ammonia reduced the production performance and altered body fat distribution quality of broilers. In this study, we examined the body fat distribution, serum metabolites and lipid metabolism gene expression of broiler exposed to ammonia. A total of 400 chickens were randomly allocated to four groups with four replicates and received ammonia treatments at 0, 25, 50 and 75 ppm, respectively, for 3 weeks. The average daily feed intake and weight gain were decreased when broiler was exposed to ammonia concentration exceeding 50 ppm (p < .05). The increased abdominal fat and reduced thickness of subcutaneous adipose were found in broilers of 75 ppm group (p < .05). When ammonia exceeded 50 ppm, the content of fat in breast muscle of broiler was increased, and when ammonia was higher than 25 ppm, the fat in liver was increased (p < .05). It showed that the fat content in liver was a sensitive index for broilers exposed to ammonia. Furthermore, ammonia exposure had no significant effect on total cholesterol and triglyceride in serum, but significantly increased the relative mRNA expression of acetyl-CoA carboxylase (p = .046) and malic enzyme in liver (p = .038), which indicated that ammonia exposure may increase the de novo fat synthesis in liver. In addition, ammonia increased the high-density lipoprotein cholesterol (p = .02) and activity of hepatic lipase in serum (p < .001), which indicated that ammonia exposure may improve the transportation of cholesterol to liver. To conclude, our results indicated that ammonia exposure might increase the de novo fat synthesis in liver and increased the transportation of cholesterol to liver. In addition, the concentration of ammonia in poultry house should be limited lower than 25 ppm based on the variation of hepatic fat content.

Abstract
Objective: This study evaluated the atypical computed tomography (CT) manifestations of thoracic sarcoidosis. Methods: Medical data of 190 patients with thoracic sarcoidosis were retrospectively reviewed. Results: The atypical CT manifestations of thoracic sarcoidosis observed were unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy(n=12, 6.3%), mediastinal lymphadenopathy without hilar lymphadenopathy(n=9, 4.7%), patchy consolidation (n=23, 12.1%), sarcoid galaxy sign (n=22, 11.6%), reversed halo sign (n=1, 0.5%), and ground-glass opacities (n=52, 27.4%). Air trapping was found in 8 of 10 patients who underwent both inspiratory and expiratory CT. Post-treatment CT scans showed improvements in most patients. Of the 12 patients with unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy, 10(83.3%) improved. Of the 9 patients with mediastinal lymphadenopathy without hilar lymphadenopathy, 8(88.9%) improved. Of the 23 patients with patchy consolidation, 15(65.2%) improved. Of the 22 patients with the sarcoid galaxy sign, 16(72.7%) improved. The patient with the reversed halo sign improved completely. Of the 52 patients with ground-glass opacities, 31(59.6%) improved. Of the 8 patients with air trapping, 7(87.5%) improved. Conclusions: The atypical imaging manifestations of thoracic sarcoidosis included unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy, mediastinal lymphadenopathy without hilar lymphadenopathy, patchy consolidation, the sarcoid galaxy sign, the reversed halo sign, ground-glass opacity, and air trapping. These lesions mostly improved after treatment. Familiarity with these atypical signs will help increase the diagnostic accuracy of imaging studies for thoracic sarcoidosis.

Abstract
Amanita exitialis is a lethal mushroom found in China. Knowledge regarding taxonomic characterization, toxin detection, general poisoning conditions, clinical manifestations, laboratory examinations, and clinical treatments for this species is currently lacking. We investigated three A. exitialis mushroom poisoning cohorts in Yunnan Province in 2014 and 2015, involving 10 patients. Mushroom samples were identified by morphological and molecular studies. Ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry was used to detect the peptide toxins in the mushroom samples. Epidemiological information, clinical data, and results of laboratory examinations were collected and analyzed. The mushroom samples were all identified as A. exitialis. The average toxin concentration decreased from the cap to the stipe to the volva, and the average concentration of the peptide toxins decreased in the order of α-amanitin > phallacidin > β-amanitin > γ-amanitin. The latency period between ingestion and the onset of symptoms was 13.9 ± 2.1 h, and the time from ingestion to hospitalization was 49.6 ± 8.5 h. The most common symptoms were nausea and vomiting (100%). Four patients died from fulminant hepatic failure. Laboratory examinations showed that the alanine transaminase, aspartate transaminase, prothrombin time, and activated partial thromboplastin time levels peaked on the third day post-ingestion. Total bilirubin and direct bilirubin values peaked on day 7. The death group and the survival group had a similar variation trend of serological indexes, but the death group had a greater change. A. exitialis is an extremely dangerous mushroom and there is a need to educate the public to avoid picking and eating wild mushrooms that have not been definitively identified.

Abstract
The aim of this in vivo study was to determine the existence of muscle-derived stem cells (MDSCs) in rat corpus cavernosum. Immunohistochemical and RT-PCR analyses were performed to determine the expression of the stem cell markers (Sca-1, Oct4, and desmin) in Sprague-Dawley (SD) rats in different age groups (10 rats in each group). Sca-1 was mainly expressed in blood vessels and cavernous sinus and demonstrated primarily cytoplasmic staining. Desmin was expressed mainly in muscle tissues and staining occurred mainly in the cytoplasm but also partially in the nucleus. An extremely small amount of double-positive stained cells (Sca-1/desmin) were detected near the cavernous sinus. Expression of the markers was significantly and negatively correlated with the age of the rats (P < 0.05). The RT-PCR results showed that the expression levels of Sca-1 and desmin significantly decreased with age (P < 0.05). Correlation analysis indicated that the expression of Sca-1 and desmin were significantly and negatively correlated with the age of rats (r = -0.929, P < 0.05). The present study provides evidence for the existence of MDSCs in rat corpus cavernosum. MDSCs may have therapeutic potential in the treatment of organic erectile dysfunction.

Abstract
In diffusion magnetic resonance imaging, accurate and reliable estimation of intravoxel fiber architectures is a major prerequisite for tractography algorithms or any other derived statistical analysis. Several methods have been proposed that estimate intravoxel fiber architectures using low angular resolution acquisitions owing to their shorter acquisition time and relatively low b-values. But these methods are highly sensitive to noise. In this work, we propose a nonconvex regularized blind compressed sensing approach to estimate intravoxel fiber architectures in low angular resolution acquisitions. The method models diffusion-weighted (DW) signals as a sparse linear combination of unfixed reconstruction basis functions and introduces a nonconvex regularizer to enhance the noise immunity. We present a general solving framework to simultaneously estimate the sparse coefficients and the reconstruction basis. Experiments on synthetic, phantom, and real human brain DW images demonstrate the superiority of the proposed approach.

Abstract
An earlier study has demonstrated that exogenous allopregnanolone (APα) can reverse the reduction of tyrosine hydroxylase (TH)-positive neurons in the substantia nigra pars compacta (SNpc) of 3-month-old male triple transgenic Alzheimer's disease mouse (3xTgAD). This paper is focused on further clarifying the origin of these new-born TH-positive neurons induced by exogenous APα treatment. We performed a deeper research in another AD mouse model, 4-month-old male APPswe/PSEN1 double transgenic AD mouse (2xTgAD) by measuring APα concentration and counting immunopositive neurons using enzyme-linked immunosorbent assay (ELISA) and unbiased stereology. It was found that endogenous APα level and the number of TH-positive neurons were reduced in the 2xTgAD mice, and these reductions were present prior to the appearance of β-amyloid (Aβ)-positive plaques. Furthermore, a single 20mg/kg of exogenous APα treatment prevented the decline of total neurons, TH-positive neurons and TH/bromodeoxyuridine (BrdU) double-positive neurons in the SNpc of 2xTgAD mice although the decreased intensity of TH-positive fibers was not rescued in the striatum. It was also noted that exogenous APα administration had an apparent increase in the doublecortin (DCX)-positive neurons and DCX/BrdU double-positive neurons of subventricular zone (SVZ), as well as in the percentage of neuronal nuclear antigen (NeuN)/BrdU double-positive neurons of the SNpc in the 2xTgAD mice. These findings indicate that a lower level of endogenous APα is implicated in the loss of midbrain dopaminergic neurons in the 2xTgAD mice, and exogenous APα-induced a significant increase in the new-born dopaminergic neurons might be derived from the proliferating and differentiation of neural stem niche of SVZ.

Abstract
Vascular endothelial growth factor-B (VEGF-B is an important member of the VEGF protein family. Recent animal studies indicated that VEGF-B signaling had determinant roles in insulin resistance, lipid distribution and metabolism in type 2 diabetes. The clinical significance of VEGF-B in type 2 diabetes is still not clear. This study aimed to correlate VEGF-B levels with biochemistry characteristics and target organ damage in type 2 diabetic patients. Serum VEGF-B levels were measured using ELISA. A crosssectional control study, which included 180 type 2 diabetic patients and 62 healthy subjects, was carried out. Diabetic patients who were undergoing insulin therapy were not included. This results showed that serum VEGF-B levels did not differ between the type 2 diabetic patients and the healthy controls (169.2∓118.8 vs 163.5∓115.2 pg/mL; P=0.734). VEGF-B levels in type 2 diabetic patients were significantly associated with the levels of c-peptide, total cholesterol and triglyceride. T-test analysis showed that the associations of serum VEGF-B levels with insulin resistance, pancreatic reserve, HDL and LDL were not significant. Regression analysis showed that VEGF-B levels were significantly correlated with diabetic retinopathy and nephropathy. No significant association between VEGF-B and macro-vasculopathy was found. In conclusion, our study findings suggested that VEGF-B levels did not differ between the type 2 diabetic patients and the normal controls. High VEGF-B levels might correlate with the presence of hyperlipidemia and target organ damage in type 2 diabetic patients.

Abstract
Secreted Frizzled-related protein 1 (sFRP1), as one of most important Wnt antagonists, is frequently silenced by promoter hypermethylation in many types of tumor, including hepatocellular carcinoma (HCC). In this study, we aimed to investigate whether restoration of sFRP1 affected HCC metastatic behavior. sFRP1 mRNA expression and promoter methylation in HCC tissues and cell lines were examined using RT-PCR and methylation-specific PCR (MS-PCR), respectively. sFRP1 protein expression was assessed by Western Blot. We generated stable HCC cell line restoration of sFRP1 in HepG2 cells, which naturally do not express detectable sFRP1 mRNA. The effects of exogenous sFRP1 on HepG2 cell invasion were investigated using trans-well assay. Also the effects of sFRP1 re-expression on the β-catenin/T-cell factor-dependent transcription activity was measured by luciferase assay.sFRP1 promoter methylation was frequently observed in HCC tissues (60%) and cell lines (75%). All samples with sFRP1 methylation showed down-regulation of sFRP1 expression in HCC cell lines. Demethylation treatment with 5-aza-20-deoxycytidine in HCC cells restored sFRP1 expression. Restoration of sFRP1 substantially impaired the invasive potentials of HepG2 cells. Moreover, exogenous sFRP1 caused significant decrease of β-catenin/T-cell factor-dependent transcription activity.These findings demonstrate that sFRP1 silencing due to promoter hypermethylation is a major event during tumorigenesis. sFRP1 is also a negative modulator of canonical Wnt signaling, which could contribute to metastasis in HCC progression, thus providing a possible therapeutic strategy against HCC.

Abstract
OBJECTIVE To describe the clinical features and management of thallium poisoning in patients with delayed hospital admission. METHODS Fourteen patients (median age 36 years) were admitted 9-19 days after ingesting food poisoned with thallium. Clinical and laboratory data, including blood and urine thallium concentrations, were collected. Patients were treated with oral Prussian blue, a chelating agent sodium dimercaptosulfonate, and hemodialysis. RESULTS All patients experienced a triad of symptoms of acute gastrointestinal upset, painful combined polyneuropathy, and hair loss after consuming poisoned food. Fatigue and skin pigmentation were observed in all patients. Abnormal liver function tests were found in 6 (42.9%) and delirium and coma were identified in 4 (28.6%). Two weeks after the poisoning, the blood and urine thallium concentration ranged from 219.0 to 1414.4 μg/L (median: 535.3) and 956.5 to 11285.0 μg/L (median: 7460.0), respectively. One patient (7.1%) with a previous history of pulmonary fibrosis died of respiratory failure in hospital. Symptoms were improved and blood or urine thallium levels were normalized in the remaining 13 patients before discharge. After a 6.5 ± 1-month follow-up, 1 patient (7.1%) developed deep venous thrombosis in the left lower limb. In another patient (7.1%), numbness in the lower limbs remained. CONCLUSION Acute thallium poisoning is commonly manifested by gastrointestinal upset, painful polyneuropathy, and significant hair loss. Treatment strategies included Prussian blue and hemodialysis, which were associated with a good outcome in this case series.

Abstract
OBJECTIVE This study analyzed patterns of suicide and suicide attempts by poisoning as reported through a national poison control system for the purpose of improving intervention and prevention. METHODS During the period of 2000 to 2006, 6440 cases of poisoning suicide were reported to the telephone consultation service system of The National Center for Poisoning Control (Chinese Center for Disease Control and Prevention). Among these records, 4728 cases had completed data for this analysis in terms of age, sex, trend of time and location, and type of poisons. RESULTS There were 60.6% female cases with the age from 10 to 90 years old. The age of cases from 20 to 39 years accounted for 54.5% of all age groups. Both the numbers and percentage in record related to poisoning consultation of oral poisoning suicide showed an increasing tendency during the 7 years. In particular, there was a drastic increase from 2004 to 2006. In addition, the high frequency of cases occurred from May to October. Hebei, Shandong, Henan, and Anhui Provinces had the highest number of cases. Pesticide poisonings were the most common method in these cases of consultation for suicide and suicide attempts. CONCLUSION This study describes epidemiological characteristics in the oral poisoning suicide cases and provides scientific basis for suicide prevention interventions.

Abstract
Replication of hepatitis delta virus (HDV) RNA occurs in the nuclei of infected cells. The replication is mediated by cellular factors containing an RNA polymerase II-like enzyme activity through a double rolling-circle mechanism and is regulated by delta antigens. In this study, UV cross-linking experiments were carried out to examine interactions between HDV RNA and proteins present in HeLa nuclear extract. Cellular proteins with molecular mass of 23 (p23), 36 (p36), 38 (p38), and 58 (p58) kDa bound to full-length HDV RNA of both genomic and antigenomic strands. Deletion analysis on the antigenomic strand mapped the interacting domain within a 79-nucleotide fragment but not at the ends of the rod-shaped viral RNA structure. The specificity of the RNA-protein interactions was demonstrated by competition experiments and the specific HDV RNA-binding proteins were purified through column chromatography. Electrophoresis mobility shift assay with the purified fractions demonstrated that the interaction between p36 and HDV RNA was relatively stable even in the presence of 0.5 M NaCl. Biochemical analysis including protein microsequencing identified the p36 as glyceraldehyde 3-phosphate dehydrogenase (GAPDH). RNase footprinting indicated that the UC-rich domain between nucleotides 379 and 414 of the HDV antigenomic RNA was involved in the GAPDH binding. Functional studies further demonstrated an enhancing effect of GAPDH on the ribozyme activity of HDV antigenomic RNA. In addition, in the presence of HDV RNA cellular GAPDH relocalized from the cytoplasm to the nucleus where HDV replication occurs. These results suggest that GAPDH is involved in the replication of HDV.

Abstract
Self-prepared fortified antibiotic eye drops are essential for the severe ocular infection. The relation of potency decay and storage conditions including temperature, concentration and duration were studied by the changes of MIC. 1% and 10% amikin, 10% and 50% pipril, and 5% and 25% vancomycin were diluted from the prarenteral antibiotics with the 5% glucose and storage at 4, -18 and -80 degrees C for 3, 7, 14 and 28 days. MICs of amikin against Pseudomonas aeruginosa, pipril and vancomycin against Staphylococcus aureus were determined by the agar diffusion method. Fluctuations of the MIC were noted during the observation period. Most of the significant changes of MIC were found during the first 7 days. When the potencies between time of zero and 28 days are compared, only 10% pipril and 25% vancomycin stored at -80 degrees C had significant change. Our conclusion is that all of the fortified antibiotic eye drops in this study can be stored in the house refrigerator or freezer for up to 28 days. High concentration may show a negative result of the preservation. Temperature does not influence the preservative effect within four weeks' observation.

Abstract
Although transforming growth factor beta (TGF-beta) superfamily ligands play critical roles in diverse developmental processes, how cells transduce signals from these ligands is still poorly understood. Cell surface receptors for these ligands have been identified, but their cytoplasmic targets are unknown. We have identified three Caenorhabditis elegans genes, sma-2, sma-3, and sma-4, that have mutant phenotypes similar to those of the TGF-beta-like receptor gene daf-4, indicating that they are required for daf-4-mediated developmental processes. We show that sma-2 functions in the same cells as daf-4, consistent with a role in transducing signals from the receptor. These three genes define a protein family, the dwarfins, that includes the Mad gene product, which participates in the decapentaplegic TGF-beta-like pathway in Drosophila [Sekelsky, J. J., Newfeld, S. J., Raftery, L. A., Chartoff, E. H. & Gelbart, W. M. (1995) Genetics 139, 1347-1358]. The identification of homologous components of these pathways in distantly related organisms suggests that dwarfins may be universally required for TGF-beta-like signal transduction. In fact, we have isolated highly conserved dwarfins from vertebrates, indicating that these components are not idiosyncratic to invertebrates. These analyses suggest that dwarfins are conserved cytoplasmic signal transducers.

Abstract
Between 1979 and 1991, 48 cases of pancreatic paraffin-embedded specimens, ie 32 carcinomas and 16 islet cell tumors, confirmed by operative and pathological examination, were studied by flow cytometric nuclear DNA content measurements. 10 specimens taken from the normal pancreatic tissue nearby the tumor transection margin and another 8 specimens in pancreatitis were compared as controls. The results demonstrated that the aneuploid rate and DNA index in pancreatic carcinoma was obviously higher than that of non-pancreatic tumor (P < 0.01). In the field of pancreatic carcinoma, the S-phase fraction was much higher in aneuploid specimens (P < 0.05). Then the nuclear DNA content was a relatively independent factor to evaluate the cancerous biological behavior. The surgical resectability of pancreatic tumors with diploid DNA was significantly higher than aneuploid ones (P < 0.05), and the later carried a shorter survival time proved by Kaplan-Meier survival analysis (P < 0.05). Finally, the clinical significance of DNA content measurements in islet cell tumor was also discussed.

Abstract
The functions of delta antigens (HDAgs) in the replication of hepatitis delta virus (HDV) have been identified previously. The small HDAg acts as a transactivator, whereas the large HDAg has a negative effect on replication. To understand the molecular mechanisms involved in the control of HDV replication, we have established a replication system in Huh-7 cells by cotransfecting a monomeric cDNA genome of HDV and a plasmid encoding the small HDAg. We demonstrate that a leucine repeat in the middle domain of the small HDAg is involved in binding to the HDV genome and transactivation of HDV replication. When the leucine repeat was disrupted by a substitution of valine for leucine at position 115, both RNA-binding and transactivation activity of the small HDAg were abolished. In contrast, the binding and transactivation activities were not affected when Leu-37 and Leu-44 of the small HDAg were replaced by valines. In addition, small and large HDAgs can interact with each other to form protein complexes in vitro. The complex formation that may lead to the trans-dominant negative regulation of large HDAg in HDV replication is mediated by a cryptic signal located between amino acid residues 35 and 65 other than the putative N-terminal leucine zipper motif. Furthermore, an extra 21-amino-acid extension near the N terminus converts the small HDAg into a pseudo-large HDAg with negative regulation activity of HDV replication even though the extreme C-terminal residue is unchanged.

Abstract
10 cases of subchondral fracture of femoral condyle or tibial plateau with or without rupture of lateral meniscus were reported. All these fractures were compressive type and were treated by open poking reduction and filling of the remaining defect with cancellous bone. Follow-up for 5 to 9 years of the 10 patients showed that they regained painless stable knee and resumed their previous works. We purposely reviewed genicular radiograms of 100 cases who had knee joint injuries, and found that certain number of them showed depression on articular surfaces of femoral condyles, possibly compressive fractures, which should have been considered more seriously. The essential points of diagnosis and the operative keys of surgery for this kind of injury have been mentioned in the paper.

Abstract
Distinct differences occur in the pigmentation and ultrastructural features of the Harderian glands in male and female hamsters. The results of a study on the effect of testosterone on the fine structure of the female Harderian glands are presented here. Glands from three groups of hamsters were examined at intervals up to 49 days: (1) testosterone injected, receiving 2 mg testosterone propionate in 0.1 ml sesame oil per day; (2) sham-injected, receiving 0.1 ml sesame oil per day; (3) untreated controls. Testosterone injections caused a reduction in the number of dark-brown pigment granules in the acinar cells starting on the 6th day, whereas clusters of tubules, typical of adult male glands, appeared on the 4th day and increased in number thereafter. Lamellar structures, normally present in the female gland, decreased in testosterone treated specimens. These changes reversed after cessation of testosterone treatment. It is concluded that exogenous testosterone administered to female hamsters modifies the pigmentation and ultrastructure of their Harderian glands towards the male type and that this is a reversable phenomenon. There also appears to be an inverse relationship between the presence of tubular clusters in the acinar cells, and the degree of pigmentation.
