Abstract
A 31-year-old female patient with refractive error in both eyes underwent small incision lenticule extraction. On the 4th day after surgery, arc-shaped peripheral corneal infiltrates appeared in the right eye. Tobramycin and dexamethasone eye drops, 0.3% gatifloxacin eye drops, and a corneal bandage lens were applied to the eye. After bacterial infection was ruled out, dexamethasone sodium phosphate was injected subconjunctivally near the corneal lesion. The symptoms improved and the corneal lesion subsided afterwards.

Abstract
Methylation is one of the most prevalent epigenetic modifications in natural organisms, and the processes of methylation and demethylation are closely associated with cell growth, differentiation, gene transcription and expression. Abnormal methylation may lead to various human diseases including cancers. Simultaneous analysis of multiple DNA demethylases remains a huge challenge due to the requirement of diverse substrate probes and scarcity of proper signal transduction strategies. Herein, we propose a sensitive and label-free method for simultaneous monitoring of multiple DNA demethylases on the basis of demethylation-activated light-up dual-color RNA aptamers. The presence of targets AlkB homologue-3 (ALKBH3) and fat mass and obesity-associated enzyme (FTO) erases the methyl group in DNA substrate probes, activating the ligation-mediate bidirectional transcription amplification reaction to produce enormous Spinach and Mango aptamers. The resulting RNA aptamers (i.e., Spinach and Mango aptamers) can bind with their cognate nonfluorescent fluorogens (DFHBI and TO1-biotin) to significantly improve the fluorescence signals. This aptamersensor shows high specificity and sensitivity with a limit of detection (LOD) of 8.50 × 10-14 M for ALKBH3 and 6.80 × 10-14 M for FTO, and it can apply to screen DNA demethylase inhibitors, evaluate DNA demethylase kinetic parameters, and simultaneously measure multiple endogenous DNA demethylases in a single cell. Importantly, this aptamersensor can accurately discriminate the expressions of ALKBH3 and FTO between healthy tissues and non-small cell lung cancer (NSCLC) patient tissues, offering a powerful platform for clinical diagnosis and drug discovery.

Abstract
Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. Previous studies have suggested that metabolites may play a pivotal mediating role in the progression of phenotypic variations. Although several metabolites had been identified as potential markers for PCOS, the relationship between blood metabolites and PCOS was not comprehensively explored. Previously, Pickrell et al. designed a robust approach to infer evidence of a causal relationship between different phenotypes using independently putative causal SNPs. Our previous paper extended this approach to make it more suitable for cases where only a few independently putative causal SNPs were identified to be significantly associated with the phenotypes (i.e., metabolites). When the most significant SNPs in each independent locus (the independent lead SNPs) with p-values of < 1 × 10-5 were used, 3 metabolites (2-tetradecenoyl carnitine, threitol, 1-docosahexaenoylglycerophosphocholine) causally influencing PCOS and 2 metabolites (asparagine and phenyllactate) influenced by PCOS were identified, (relative likelihood r < 0.01). Under a less stringent threshold of r < 0.05, 7 metabolites (trans-4-hydroxyproline, glutaroyl carnitine, stachydrine, undecanoate, 7-Hoca, N-acetylalanine and 2-hydroxyisobutyrate) were identified. Taken together, this study can provide novel insights into the pathophysiological mechanisms underlying PCOS; whether these metabolites can serve as biomarkers to predict PCOS in clinical practice warrants further investigations.

Abstract
Objective: To investigate the consistency between the hearing handicap inventory (HHI) and pure-tone audiometry (PTA) scores in assessing hearing status to provide valuable insights for clinical application. Methods: Retrospective analysis of clinical data and the HHI reporting status of 6540 patients admitted between April 2020 and July 2022 for self-reported unilateral hearing loss who met the study inclusion and exclusion criteria. The kappa coefficient was used to evaluate the consistency of HHI and PTA in assessing the hearing status of the participants. Results: The PTA results showed that among the 6540 participants, 3895 exhibited normal hearing, 1434 showed mild hearing loss, 809 presented with moderate hearing loss, and 402 showed severe hearing loss. The mean hearing thresholds from 0.5 to 4 kHz in healthy ears ranged from 3.65 to 18.45 dB HL, with a mean of 10.83 ± 5.29 dB HL; in ears affected by hearing loss, this ranged from 35 to 125 dB HL, with a mean of 69.63 ± 28.45 dB HL. The HHI scores showed that 4820 people had normal hearing, 1245 had mild-to-moderate hearing loss, and 475 had severe hearing loss. The kappa coefficients of normal, mild-to-moderate, and severe hearing loss were 0.312, 0.223, and 0.716, respectively (P = .001). The consistency between the 2 groups was particularly significant in the assessment of severe hearing loss. Using the PTA results as a benchmark, the sensitivity, specificity, positive predictive value, and negative predictive value of the HHI were found to be 73.08%, 87.83%, 95.60%, and 70.98%, respectively. Conclusion: The HHI and PTA results were consistent in the assessment of hearing status, particularly in the assessment of severe hearing loss, and the level of consistency between the 2 methods was high. The combined use of these tools can facilitate a comprehensive assessment of the auditory status of patients with hearing loss.

Abstract
Objective: The study investigated the clinical distribution, antimicrobial resistance and epidemiologic characteristics of hypervirulent Carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) in a hospital in Henan Province to provide a scientific basis for antibiotic use and nosocomial infection prevention and control. Methods: A retrospective analysis of the clinical data from the cases was carried out in this study. Clinical data of patients infected with the CRKP strain isolated from the clinical microbiology laboratory of Henan Provincial Hospital of Traditional Chinese Medicine from January 2020 to December 2022 were retrospectively analyzed. A string test, virulence gene screening, serum killing, and a G. mellonella infection model were used to screen hv-CRKP isolates. The clinical characteristics of hv-CRKP and the drug resistance rate of hv-CRKP to twenty-five antibiotics were analyzed using WHONET 5.6. Carbapenemase phenotypic characterization of the hv-CRKP was performed by colloidal gold immunochromatographic assay, and Carbapenemase genotyping, multi-locus sequence typing (MLST) and capsular serotyping of hv-CRKP isolates were performed by PCR and Sanger sequencing. Results: A total of non-duplicate 264 CRKP clinical isolates were detected in the hospital from 2020 to 2022, and 23 hv-CRKP isolates were detected, so the corresponding detection rate of hv-CRKP was 8.71% (23/264). The hv-CRKP isolates in this study were mainly from the intensive care unit (10/23) and neurosurgery department (8/23), and the main sources of hv-CRKP isolates were sputum (10/23) and bronchoalveolar lavage fluid (6/23). The hv-CRKP isolates in this study were highly resistant to β-lactam antibiotics, fluoroquinolones and aminoglycosides, and were only susceptible to colistin, tigecycline and ceftazidime/avibactam. The detection rate of the blaKPC-2 among 23 hv-CRKP isolates was 91.30% (21/23) and none of the class B and class D carbapenemases were detected. Results of MLST and capsular serotypes showed that ST11 type hv-CRKP was the dominant strain in the hospital, accounting for 56.52% (13/23), and K64 (9/13) and KL47 (4/13) were the major capsular serotypes. Conclusion: The hv-CRKP isolates from the hospital are mainly from lower respiratory tract specimens from patients admitted to the intensive care department and the drug resistance is relatively severe. The predominant strains with certain polymorphisms are mainly composed of the KPC-2-producing ST11-K64 and ST11-KL47 hv-CRKP isolates in the hospital.

Abstract
Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic pathogenic bacterium with complex pathogenesis and drug resistance mechanisms. It has high morbidity and mortality and can cause acute and chronic infections in immunocompromised individuals, with lung infections, wound infections, and bloodstream infections being the most common. The animal infection model of P. aeruginosa is of great value for in-depth research on the pathogenicity, drug resistance, and therapeutic measures of P. aeruginosa by simulating the pathways of human bacterial infections. This article firstly summarizes the selection, anesthesia, and disposal of experimental animals in the construction of animal models of P. aeruginosa infection, and then reviews the methods of construction, model evaluation, and applications of animal models of P. aeruginosa pulmonary infection, wound infection, and bloodstream infection, in order to provide a reference for scientific research related to P. aeruginosa infectious diseases.

Abstract
BackgroundRenal ischemia-reperfusion injury (IRI) is an inevitable occurrence during kidney transplantation. Mitophagy, ferroptosis, and the associated immune microenvironment (IME) have been shown to play important roles in renal IRI. However, the role of mitophagy-associated IME genes in IRI remains unclear. In this study, we aimed to construct a prediction model of IRI prognosis based on mitophagy-associated IME genes.MethodThe specific biological characteristics of the mitophagy-associated IME gene signature were comprehensively analyzed using public databases such as GEO, Pathway Unification, and FerrDb. Correlations between the expression of prognostic genes and immune-related genes and IRI prognosis were determined by Cox regression, LASSO analysis, and Pearson’s correlation. Molecular validation was performed using human kidney 2 (HK2) cells and culture supernatant as well as the serum and kidney tissues of mice after renal IRI. Gene expression was measured by PCR, and inflammatory cell infiltration was examined by ELISA and mass cytometry. Renal tissue damage was characterized using renal tissue homogenate and tissue sections.ResultsThe expression of the mitophagy-associated IME gene signature was significantly correlated with IRI prognosis. Excessive mitophagy and extensive immune infiltration were the primary factors affecting IRI. In particular, FUNDC1, SQSTM1, UBB, UBC, KLF2, CDKN1A, and GDF15 were the key influencing factors. In addition, B cells, neutrophils, T cells, and M1 macrophages were the key immune cells present in the IME after IRI. A prediction model for IRI prognosis was constructed based on the key factors associated with the mitophagy IME. Validation experiments in cells and mice indicated that the prediction model was reliable and applicable.ConclusionWe clarified the relationship between the mitophagy-related IME and IRI. The IRI prognostic prediction model based on the mitophagy-associated IME gene signature provides novel insights on the prognosis and treatment of renal IRI.

Abstract
In recent years, with the problem of aging population in China being prominant, the number of patients with chronic wounds such as diabetic foot, pressure ulcer, and vascular ulcer is increasing. Those diseases seriously affect the life quality of patients and increase the economy and care burden of the patients' family, which have been one of the most urgent clinical problems. Many researches have confirmed that adipose stem cells can effectively promote wound healing, while exogenous protease is needed, and there are ethical and many other problems, which limit the clinical application of adipose stem cells. Adipose stem cell matrix gel is a gel-like mixture of biologically active extracellular matrix and stromal vascular fragment obtained from adipose tissue by the principle of fluid whirlpool and flocculation precipitation. It contains rich adipose stem cells, hematopoietic stem cells, endothelial progenitor cells, and macrophages, etc. The preparation method of adipose stem cell matrix gel is simple and the preparation time is short, which is convenient for clinical application. Many studies at home and abroad showed that adipose stem cell matrix gel can effectively promote wound healing by regulating inflammatory reaction, promoting microvascular reconstruction and collagen synthesis. Therefore, this paper summarized the preparation of adipose stem cell matrix gel, the mechanism and problems of the matrix gel in promoting wound repair, in order to provide new methods and ideas for the treatment of chronic refractory wounds in clinic.

Abstract
Although gastric cancer with para-aortic lymph node (PAN) metastasis is commonly regarded as unresectable, surgeons have explored the optimal treatment for patients with PAN metastases limited to No.16a2/b1 in the past few decades. Preoperative systemic therapy combined with D2 gastrectomy plus PAN dissection may improve the prognosis of these patients. In this multicenter phase II trial, 29 gastric cancer patients with PAN metastasis limited to No.16a2/b1 will receive preoperative treatment with nab-paclitaxel, oxaliplatin, S-1 (nab-POS: nab-paclitaxel, oxaliplatin, S-1) and sintilimab followed by D2 gastrectomy plus PAN dissection; and postoperative treatment with oral S-1, intravenous sintilimab and intraperitoneal paclitaxel. The end points for the study are 3-year overall survival, 3-year disease-free survival, pathological response rate, incidence of postoperative complications and adverse events.

Abstract
An efficient and straightforward approach for the synthesis of carbamoylated chroman-4-ones has been well-developed. The reaction is triggered through the generation of carbamoyl radicals from oxamic acids under metal-free conditions, which subsequently undergoes decarboxylative radical cascade cyclization on 2-(allyloxy)arylaldehydes to afford various amide-containing chroman-4-one scaffolds with high functional group tolerance and a broad substrate scope.

Abstract
Pyogenic granuloma (PG) is a benign fibrovascular proliferative lesion on the skin and mucous membranes, but its pathogenesis remains unclear. PG usually occurs on the head and neck region, fingers and toes. The oral gingiva is the most common location for pregnant patients, while it is rarely found in the nasal cavity. This case is notable not only for its uncommon site and size but also for its gradual growth after delivery. Endoscopic surgery can achieve the desired cosmetic effect and a satisfactory airway. A rapidly growing hemorrhagic lesion in the nasal cavity should be considered as a differential diagnosis.

Abstract
Ameloblastomas are slow-growing, aggressive odontogenic epithelial tumors that originate from the jawbone. One of the most easily relapsing maxillofacial tumors, ameloblastomas mainly occur in the mandibular molar area and ascending branch, although they can occasionally occur in the nasal cavity and paranasal sinuses. A 14-year-old child with autism spectrum disorder underwent sinus computed tomography (CT) under anesthesia. A swollen tumor had grown in the left maxillary sinus, and the bone of the maxillary sinus was damaged. Nine months after the first operation, recurrence was observed in the left maxillary sinus. The pathological diagnosis was ameloblastoma. Due to the child's inability to communicate and cooperate with the treatment normally, he underwent endoscopic surgery again combined with low-temperature plasma treatment. No tumor recurrence was found on reexamination 6 months after surgery.

Abstract
BACKGROUND Genome-wide association studies (GWASs) have identified numerous genetic variants associated with attention-deficit/hyperactivity disorder (ADHD), which is considered highly genetically heritable. However, because most of the variants located in the non-coding region of the human genome, the onset of ADHD requires further exploration. METHODS The risk genes involved in ADHD were identified by integrating GWAS summary data and expression quantitative trait locus (eQTL) data using summary-data-based Mendelian randomization (SMR) method. We then used a stratified linkage disequilibrium score regression (LDSR) method to estimate the contribution of ADHD-relevant tissues to its heritability to screen out disease-relevant tissues. To determine the ADHD-relevant cell types, we used an R package for expression-weighted cell type enrichment (EWCE) analysis. RESULTS By integrating the brain eQTL data and ADHD GWAS data using SMR, we identified 247 genes associated with ADHD. The LDSR applied to specifically expressed genes results showed that the ADHD risk genes were mainly enriched in brain tissue, especially in the mesencephalon, visual cortex, and frontal lobe regions. Further cell-type-specific analysis suggested that ADHD risk genes were highly expressed in excitatory neurons. CONCLUSION The study showed that the etiology of ADHD is associated with excitatory neurons in the midbrain, visual cortex, and frontal lobe regions.

Abstract
Purpose: The increasing prevalence of sarcopenia remains an ongoing challenge to health care systems worldwide. The lack of treatments encouraged the discovery of human proteomes to find potential therapeutic targets. As one of the major components of the human proteome, plasma proteins are functionally connected with various organs of the body to regulate biological processes and mediate overall homeostasis, which makes it crucial in various complex processes such as aging and chronic diseases. By performing a systematic causal analysis of the plasma proteome, we attempt to reveal the etiological mechanism and discover drug targets for sarcopenia. Methods: By using data from four genome-wide association studies for blood proteins and the UK Biobank data for sarcopenia-related traits, we applied two-sample Mendelian randomization (MR) analysis to evaluate 310 plasma proteins as possible causal mediators of sarcopenia-related traits: appendicular lean mass (ALM) and handgrip strength (right and left). Then we performed a two-sample bidirectional Mendelian randomization analysis for the identified putatively causal proteins to assess potential reverse causality that the trait values may influence protein levels. Finally, we performed phenome-wide MR analysis of the identified putatively causal proteins for 784 diseases to test the possible side effects of these proteins on other diseases. Results: Five plasma proteins were identified as putatively causal mediators of sarcopenia-related traits. Specifically, leukocyte immunoglobulin-like receptor subfamily B member 2 (LILRB2), asporin (ASPN), and contactin-2 (CNTN2) had potential causal effects on appendicular lean mass, and ecto-ADP-ribosyltransferase 4 (ART4) and superoxide dismutase 2 (SOD2) had putative causal effects on the handgrip strength, respectively. None of the five putatively causal proteins had a reverse causality relationship with sarcopenia-related traits, and no side effects on other diseases were identified. Conclusion: We identified five plasma proteins that may serve as putatively potential novel drug targets for sarcopenia. Our study attested to the value of two-sample MR analysis in identifying and prioritizing putatively potential therapeutic targets for complex diseases.

Abstract
Endoscopic full-thickness resection (EFTR) allows completely resecting deep submucosal tumors (SMTs) in the gastrointestinal wall, which has a broad application prospect in clinic. However, its application and promotion are limited by complex surgical procedures and high surgical risk. Various auxiliary traction techniques are expected to reduce the operation difficulty and risk of EFTR and improve its operative success rate. To provide a reference for clinicians, we summarize various auxiliary traction techniques in EFTR in this article. The clip-with-line method is simple to operate and widely used, whereas its traction is limited and there is a risk of clip falling off. The snare traction method and the clip-snare traction method has advantage of large traction force, but its thrust is affected by the hardness of snare. The traction point of the grasping forceps traction method is flexible and easy to adjust. Nevertheless, it requires the use of a dual-channel upper endoscope, which is difficult to operate. The transparent cap traction method and the full-thickness resection device traction method takes a short time and is easy to promote, whereas the resectable lesion is limited, and the size of the lesion may affect the success rate. In contrast, the suture loop needle-T-tag tissue anchors assisted method has a large resection range, but the operation is complicated and the feasibility has not been verified. The robot-assisted method has flexible operation and excellent visualization, whereas it is expensive and difficult to operate. There is no report of the application of magnetic anchor technology in EFTR, but it may have good application prospects in the auxiliary traction of EFTR.

Abstract
In this study, soil samples were collected from the eastern edge of the Qinghai Tibet Plateau in December 2019. The level and distribution characteristics of organophosphate esters (OPEs) in seasonal frozen soil were analyzed, and their sources were discussed. The results showed that the target analytes including tri-n-butyl phosphate (TnBP), tris(2-ethylhexyl) phosphate (TEHP), tributoxyethyl phosphate (TBEP), triphenyl phosphate (TPhP), tri(2-chloroethyl) phosphate (TCEP), trichloropropyl phosphate (TCPP), and tris-(2,3-dichloropropyl) phosphate (TDCPP) were detected with 100% frequency. Levels of Σ7OPEs in topsoil (0-10 cm) and sub topsoil (10-20 cm) were 146.7-348.7 ng·g-1 (mean:231.1 ng·g-1) and 206.5-333.2 ng·g-1 (mean:260.2 ng·g-1), respectively. The Σ7OPEs content level is comparable to that of urban soil,which is worthy of attention. TBEP and TDCPP were the most abundant compounds in the plateau soil. Point source emissions have significant influence on the spatial distribution of OPEs, and regional deposition of OPEs contributes to all sampling sites. The migration ability of different OPE compounds in soil was different. Stronger migration ability was observed for aromatic OPEs (TPhP) than chlorinated OPEs. Principal component analysis showed that the main sources of OPEs in plateau soil were atmospheric wet and dry deposition, manufactured consumer materials, and the release of OPEs from automobile interior decoration.

Abstract
Objective: To discuss the prediction efficacy of Down's screening serological indicators in the second trimester of gestational hypertension (GH). Methods: 64 849 pregnant women who had undergone regular check-ups at the Beijing Obstetrics and Gynecology Hospital from June 2013 to June 2019 and finally gave birth were the subjects of the study. There were 3 808 cases of the GH group (including patients with GH, preeclampsia, and eclampsia diagnosed) and 61 041 cases of non-GH group respectively. 3 ml of fasting venous blood was drawn during 14-19 weeks of pregnancy, and body weight, serum β-human chorionic gonadotropin (β-HCG), free estriol (uE3) and alpha fetal protein (AFP) were obtained through physical check and laboratory testing. β-HCG, AFP, uE3 were analyzed by using the corresponding median times of gestational age (MOM value), and multivariate logistic regression model and receiver operating characteristic curve (ROC curve) were used to analyze the predictive efficiency of serological indicators. Results: Among 64 849 research subjects, the GH group (3 808 cases) and the non-GH group (61 041) were (29.51±2.72), (29.38±2.68) years old, the weights were (65.46±12.17), (58.73±9.13) kg, gestational age of blood collection were (16.53±0.89) and (16.58±0.90) weeks respectively. The analysis of multivariate logistic regression model showed that the risk of GH increased with the increase of body weight, β-HCG and AFP concentration, OR (95%CI) values were 1.059 (1.056-1.062), 1.329 (1.188-1.487) and 1.195 (1.125-1.269); so did when the concentration of uE3 decrease, OR (95%CI) value was 0.527 (0.464-0.599). ROC curve analysis results show that age, weight, serum AFP, β-HCG, uE3 and multivariate diagnosis all have predictive efficiency for GH (P values<0.05); combined diagnosis of multiple indicators and weight AUC (95%CI) were 0.684 (0.675-0.693) and 0.673 (0.663-0.682), but the Youden index, sensitivity, and specificity of the two were relatively small. Conclusion: The β-HCG, AFP and uE3 of Down's screening in the second trimester of pregnancy were relatively low in predicting GH.

Abstract
Pseudomonas aeruginosa is one of the common multidrug-resistant bacteria in the clinic. Because it can produce a "protective" biofilm, it can affect the penetration and killing efficacy of antibacterial drugs, leading to the formation of a persistent and persistent chronic infection in the host. Biofilms make Pseudomonas aeruginosa resistant to antibacterials and evasive to the host's immune system. Therefore, traditional conventional antibacterials are difficult to achieve effective bactericidal treatment. Understanding the process of P. aeruginosa biofilm formation and the regulatory mechanisms that affect biofilms can provide ideas and methods for our future research on new antibacterial drugs.

Abstract
Objective Waardenburg syndrome type 2 (WS2) is an autosomal dominant syndrome, characterized by bright blue eyes, hearing loss, and depigmented patches of hair and skin. It exhibits high phenotypic and genetic heterogeneity. We explored the molecular etiology in a Chinese family with WS2. Methods We recruited a three-generation family with three affected members. Medical history was obtained from all family members who underwent detailed physical examinations and audiology tests. Genomic DNA was extracted from peripheral blood of each individual, and 139 candidate genes associated with hearing loss were sequenced using Illumina HiSeq 2000 (Illumina Inc., San Diego, CA, USA) and verified by Sanger sequencing. Results Genetic evaluation revealed a novel nonsense heterozygous variant, NM_006941.4: c.342G>A (p.Trp114Ter) in exon 2 of the SOX10 gene in the three affected patients; no unaffected family member carried the variation. We did not detect the variation in 500 Chinese individuals with normal hearing or in 122 unrelated Chinese families with hearing loss, suggesting that it was specific to our patients. Conclusions We identified a novel heterozygous nonsense variation in a family with syndromic hearing loss and WS2. Our findings expand the pathogenic spectrum and strengthen the clinical diagnostic role of SOX10 in patients with WS2.

Abstract
OBJECTIVE To evaluate the genotype-phenotype correlation of branchio-otic syndrome (BOS) in a Chinese family. METHODS The proband in this study was an 18-month-old boy with hearing loss, preauricular pit, and branchial fistula without a renal anomaly. We collected blood samples from 6 family members, including 4 who were affected by the syndrome. Targeted next-generation sequencing and Sanger sequencing were performed to identify pathogenic mutations in this family. RESULTS Pedigree analysis indicated that the mode of inheritance in the family was consistent with the autosomal dominant pattern. Hearing loss was the most common manifestation, occurring in 4 patients. Other findings included preauricular pits (n=2), cervical fistulas (n=3) and abnormal pinnae (n=4). None of the patients had renal anomalies. Evaluation by pure-tone audiometry and temporal bone imaging demonstrated bilateral mixed hearing loss, as well as middle ear and inner ear deformities, in two patients. Mutational analysis of candidate genes in the selected patients led to the identification of a novel frameshift variant NM_000503.4: c.1075_1077delinsAT (p.Gly359Ilefs*7) in the EYA1 gene. CONCLUSIONS The EYA1 c.1075_1077delinsAT mutation is the causative variant in the Chinese family with BOS, although the penetrance is variable within patients.

Abstract
OBJECTIVE To expose the spectrum and frequency of GJB2, GJB3, SLC26A4 and MT-RNR1 in northwest China and to investigate the underlying causative genes in patients without common mutations. METHODS We analyzed the mutation screening results of GJB2, GJB3, SLC26A4 and MT-RNR1 in 398 unrelated severe-to-profound probands with bilateral, symmetrical sensorineural hearing loss. Subsequently, we selected 10 probands with a significant family history of inherited hearing loss (HL) that did not have the above four common gene mutations to perform next-generation sequencing (NGS) of 139 known deafness genes, followed by co-segregation analysis of all available family members. RESULTS Among the 398 patients, 69 (17.34%) had the biallelic GJB2 gene mutations, and the most common mutations were c.235delC, c.109G>A and c.299_300delAT, with allele frequencies of 12.31%, 3.38% and 3.89%, respectively. A total of 63 (15.83%) cases with biallelic SLC26A4 mutations were detected, and the most common pathogenic alleles were c.919-2A>G, c.2168A>G and c.1174A>T, with allele frequencies of 9.17%, 2.26% and 0.88%, respectively. Mitochondrial gene mutations were detected in 9 (2.26%) patients, with 5 cases of mitochondrial DNA (mtDNA) m.1555A>G mutation and 4 cases of mtDNA m.1095T>C mutation. In 10 probands with a clear family history of HL, NGS showed two novel pathogenic variants in 2 families, including c.4129C>T/c.3268C>T in LOXHD1, c.334G>A/c.2968G>T in CDH23. Sanger sequencing confirmed that these variants segregated with the HL in each family. CONCLUSIONS Our results showed that GJB2 and SLC26A4 were the two major HL-causing genes in northwest China. The most common mutation alleles in GJB2 were c.235delC, c.109G>A and c.299_300delAT, and those in SLC26A4 were c.919-2A>G, c.2168A>G and c.1174A>T. In addition, both genes and their loci can be used as the first selection of deafness gene screening. Additionally, for patients who did not have mutations of these common genes, NGS provided an efficient diagnosis for increasing known deafness genes.

Abstract
Objective: To identify the epidemic clones of MRSA isolates at a hospital in shanghai. Methods: A total of 72 MRSA isolates have been isolated from a second grade hospital between 2017 and 2018, including 32 CA-MRSA isolates, 13 HA-MRSA isolates and 26 MRSA isolates from environment. In this study, MLST and PFGE typing methods were used to analyze the molecular epidemiology of the MRSA isolates. Results: A total of 72 MRSA isolates have been obtained including 46 isolates from clinical specimens, 26 isolates from environments. The 46 MRSA isolates from clinical specimens consisted of 33 CA-MRSA (community-acquired MRSA) and 13 HA-MRSA (hospital-acquired MRSA). Furthermore, these patients infected with MRSA isolates were mostly distributed in the department of geriatrics (34.8%, 16/46), internal medicine (26.1%, 12/46) and surgery (26.1%, 12/46). MLST typing results showed that ST764 was predominant in isolates from both clinical specimens and hospital environments. Furthermore, PFGE typing results showed that most ST764 MRSA had high homolog (>90%). Conclusion: ST764 MRSA isolates might spread in community, hospital and environments. Therefore, continuous monitoring of MRSA and its variation may be useful in understanding the involvement of epidemic clone, and in searching new strategies to control MRSA infection.

Abstract
INTRODUCTION To examine the effects and safety of oxytocin administered intramuscularly or intravenously for preventing postpartum hemorrhage (PPH) in the third stage of labor after vaginal deliveries. MATERIAL AND METHODS Before data extraction, the review was registered with the PROSPERO International Prospective Register of Systematic Reviews (registration No. CRD42019145912). We searched the published electronic databases, including Medline, EMBASE, PubMed, Web of Science, CNKI, VIP, Wanfang, the Cochrane Library, clinicaltrial.gov and PROSPERO database, from their inception until February 2019. We included all randomized controlled trials (RCTs) comparing intramuscular and intravenous oxytocin administered just after the birth of the anterior shoulder or soon after the birth of the baby during a vaginal delivery. The primary outcomes were the incidence of PPH and severe PPH. PPH was defined as a blood loss ≥500 ml within 24 hours after vaginal birth. Severe PPH refers to a clinically estimated blood loss equal to or greater than 1000 mL within 24 hours after vaginal birth. Statistical heterogeneity was assessed by the I2 test, the Cochran Q statistic and the Galbraith plot for heterogeneity. RESULTS Six RCTs, including 7320 women undergoing vaginal delivery, were identified in the meta-analysis. Women who were randomized to have intravenous oxytocin for the third stage of labor had a significantly lower incidence of PPH (relative risk 1.35, 95% CI 1.11-1.64, p = 0.003), severe PPH (relative risk 1.61, 95% CI 1.05-2.46, p = 0.03) and blood transfusion (relative risk 2.50, 95% CI 1.37-4.59, p = 0.003) compared with those who were randomized to have intramuscular oxytocin during the third stage of labor after vaginal delivery. There was no significant difference with regard to changes in hemoglobin level, third stage of labor duration, mean postpartum blood loss, or the incidences of a need for additional uterotonics and of retained placenta or manual removal of placenta between groups. CONCLUSIONS For women in the third stage of labor who are undergoing a vaginal delivery, the use of intravenous oxytocin reduces the incidence of PPH, severe PPH and blood transfusion and does not increase the risk of adverse effects compared with intramuscular oxytocin.

Abstract
Objective: To study the role of virtual gastroscopy simulator in the examination of clinical practice skills of gastrointestinal specialists. Methods: A multi-center empirical study was carried out. In June 2018, ninety participants from three tertiary care teaching hospitals in China, including Zhongshan Hospital of Fudan University, Shanghai Tongji Hospital and Xiangya Hospital of Central South University, took part in the examination. Participants were selected as follows: 30 specialists without any experience of gastroscopy exams, 30 with basic knowledge (gastroscopy exams <500 cases) and 30 with good skill (gastroscopy exams ≥500 cases). These 90 students participated in this empirical study after theoretical study and simulator training. Among them, 50 (55.6%) were undergraduates, 25 (27.8%) masters, and 15 (16.7%) doctors; 42 (46.7%) were residents, 39 (43.3%) attending physicians, and 9 (10.0%) deputy chief physicians. The assessment was divided into two parts. The first part was to use the simulator (GI mentor II) for ballooning within 10 minutes, with a total score of 40 points. The second part was a complete gastroscopy exam on the simulator, including preparation before gastroscopy exam, gastroscopy exam, post - exam management and related knowledge quiz. The difficulty and discrimination of the assessment plan were evaluated by the extreme grouping method parameters (difficulty P definition: <0.3 was difficult, 0.3 to 0.7 was medium, ≥0.7 was easy; discrimination degree D definition: <0 was poor, 0 to 0.2 was medium, ≥0.2 was good), and by comparing the virtual gastroscopy assessment scores of different experience, academic, and professional title groups. The score analysis of the student group was expressed using the mastering rate (the average score divided by the total score). The data of the normal distribution was represented by (mean±SD) (range), and the data of the nonnormal distribution was represented by M (P25, P75). Kruskal-Wallis non-parametric test was used for comparison between groups. Results: The total score of 90 students was (82.9±10.9) (55.8 to 99.0), and the mastering rate was 82.9%. The overall difficulty of the first and the second parts were 0.78 and 0.76, respectively, and the difficulty level was easy. The overall discrimination of the first and the second parts were 0.70 and 0.67, respectively, and the discrimination was good. The stratified analysis was performed according to the professional title. The median score was 83.2 (75.5, 89.0) in the residents, 82.5 (71.7, 93.6) in the attending physicians, and 93.5 (88.5, 99.0) in the deputy chief physicians, and the difference was statistically significant (H=6.213, P=0.045). According to the stratification analysis of academic qualifications, the median score was 81.7 (73.0, 87.5) in participants with undergraduate degree, 91.0 (79.0, 95.0) in those with master degree and 88.0 (81.7, 93.5) in those with doctor degree, whose difference was statistically significant (H=9.233, P=0.010). The stratified analysis of the second part showed that the median scores of the "operational process" part of the low, medium and high basis group were 33.0 (30.5, 36.5), 34.0 (32.0, 36.0) and 37.0 (35.0, 37.5), respectively, whose difference was statistically significant (H=7.603, P=0.022). The median scores of the "operational process" section of the resident, attending physician, and deputy chief physician were 33.0 (30.5, 35.0) points, 36.0 (34.0, 37.5) points and 37.0 (37.0, 37.5) points, respectively, whose difference was statistically significant (H=18.563, P=0.001). Conclusions: The virtual gastroscopy simulator can reflect the true level of gastroscopy exam skills of the students. The examination questions are moderately difficult, and there is a good discrimination of the exam.

Abstract
Apoptosis is the major cause of cardiomyocyte death in myocardial ischemia/reperfusion injury (MI/RI). Increasing evidence suggests that microRNAs (miRNAs) can contribute to the regulation of cardiomyocytes apoptosis by posttranscriptional modulation of gene expression networks. However, the effects of miR-327 in regulating MI/RI-induced cardiomyocytes apoptosis have not been extensively investigated. This study was performed to test whether miR-327 participate in cardiomyocytes apoptosis both in vitro and in vivo, and reveal the potential molecular mechanism of miR-327 regulated MI/RI through targeting apoptosis repressor with caspase recruitment domain (ARC). Sprague-Dawley (SD) rats were subjected to MI/RI by left anterior descending coronary artery occlusion for 30 min and reperfusion for 3 hr. H9c2 cells were exposed to hypoxia for 4 hr and reoxygenation for 12 hr to mimic I/R injury. miRNA-327 recombinant adenovirus vectors were transfected into H9c2 cells for 48 hr and rats for 72 hr before H/R and MI/RI treatment, respectively. The apoptosis rate, downstream molecules of apoptotic pathway, and the target reaction between miRNA-327 and ARC were evaluated. Our results showed that miR-327 was upregulated and ARC was downregulated in the myocardial tissues of MI/RI rats and in H9c2 cells with H/R treatment. Inhibition of miR-327 decreased the expression levels of proapoptotic proteins Fas, FasL, caspase-8, Bax, cleaved caspase-9, cleaved caspase-3, and the release of cytochrome-C, as well as increasing the expression levels of antiapoptotic protein Bcl-2 via negative regulation of ARC both in vivo or vitro. In contrast, overexpression miR-327 showed the reverse effect. Moreover, the results of luciferase reporter assay indicated miR-327 targets ARC directly at the posttranscriptional level. Taken together, inhibition of miR-327 could attenuate cardiomyocyte apoptosis and alleviate I/R-induced myocardial injury via targeting ARC, which offers a new therapeutic strategy for MI/RI.

Abstract
Objective: To investigate the application value of Overlap anastomosis in Billroth I digestive tract reconstruction after laparoscopic distal gastrectomy in gastric cancer. Methods: Clinical data of 68 stage T1-2 gastric cancer patients undergoing laparoscopic distal gastrectomy for D2 radical gastrectomy from January 2015 to January 2016 at China Japan Union Hospital of Jilin University were retrospectively analyzed. Inclusion criteria: (1) no distant metastasis of gastric cancer confirmed by gastroscopy and pathology before surgery; (2) T1-2 tumor with diameter <3 cm; (3) the lesion locating in the antrum of the stomach with distance >1 cm from the pylorus, and no invasion into middle area; (4) R0 resection confirmed by postoperative pathology; (5) no history of abdominal surgery. Among 68 cases,23 cases were in Overlap anastomosis group and 45 cases in Billroth I anastomosis group. D2 lymph node dissection and distal gastrectomy were performed in both groups. In the Overlap anastomosis group, the duodenum and stomach were severed by a linear stapler under endoscopy, and the residual gastric curve anastomotic opening was selected. According to the tension between the duodenum and the remnant stomach, the anastomotic opening was selected at the upper edge of the remnant duodenum, and the anastomosis between the posterior wall of the remnant stomach and the upper wall of the duodenum was completed by placing the stapler under endoscopy. Then the common opening was closed and the remnant duodenum was resected. In the traditional Billroth I anastomosis group, pneumoperitoneum was discontinued after amputation of the duodenum under laparoscopy. The median incision of the upper abdomen was 9-12 cm. The distal stomach was pulled out to complete the excision of specimens, the extraction of specimens and Billroth I digestive tract reconstruction. The intraoperative and postoperative conditions of the two groups were compared with student t test (continuous variable) and chi-square test (categorica variable). Results: Of the 68 patients,39 were males and 29 were females,with age of (65.5±10.2)(51 to 77)years. Differences in baseline data between Overlap group and Billroth I group were not statistically significant (all P>0.05). Laparoscopic surgery was successfully performed in both groups without conversion to open operation. As compared with the Billroth I group, the Overlap group had significantly shorter operation time [(149.8±10.1) minutes vs. (169.8±15.3) minutes, t=5.658,P=0.008], shorter anastomotic time of digestive tract reconstruction [(31.2±3.8) minutes vs. (36.3±3.3) minutes, t=3.389, P=0.003] and shorter abdominal incision length [(4.5±0.9) cm vs.(11.0±2.3) cm, t=13.244,P=0.004]. There were no significant differences between two groups in intraoperative blood loss [(92.9±22.4) ml vs. (87.0±7.3) ml,t=1.186,P=0.366], number of lymph node dissected (28.4±5.7 vs. 27.3±5.2, t=0.838, P=0.383), postoperative flatus time [(4.4±2.1) days vs.(4.2±1.8) days, t=0.391, P=0.563], morbidity of postoperative complication [4.3%(1/23) vs. 6.7%(3/45), χ2=0.148,P=0.701]. All the patients were followed up for 28±10 (10-46) months. There were no long-term complications, recurrence or death in two groups. Conclusion: Overlap anastomosis in Billroth I digestive tract reconstruction after laparoscopic distal gastrectomy is safe and effective, and can reduce the anastomosis time.

Abstract
Objective: To summarize and analyze the clinical manifestation of conjunctival papilloma, its relationship with human papillomavirus (HPV) infection and the recurrence after the combination of operation and pharmacotherapy. Methods: A retrospective case series study. Analysis of 40 patients (41 eyes) with conjunctival papilloma treated at Peking Union Medical College Hospital from January 2008 to June 2018 was performed. All patients were given routine blood and urine, hepatitis B virus surface antigen, antibodies to hepatitis C virus, antibodies to human immunodeficiency virus and antibodies to Treponema pallidum testing, and HPV testing for the urethra epithelial tissue. Direct contact of the tumor with instruments was avoided during surgery, and freezing treatment was combined. HPV testing was performed for the resected conjunctival papilloma. Multiple medications were used after surgery. Results: In 40 cases with 41 eyes, there were 22 males (23 eyes) and 18 females (18 eyes). A single tumor was seen in 27 eyes, and multiple tumors were seen in 14 eyes. Thirteen patients (13 eyes) older than 50 years old had pedicel-free papillpma, and 27 patients (28 eyes) aged from 12 to 40 years had pedicel-type papillpma. All cases were confirmed by pathology as conjunctival papilloma, of which 9 cases showed moderate to severe atypical hyperplasia on squamous cells. The HPV test was positive in 17 out of the 40 cases (42.5%) of conjunctival papilloma. Urine test results of 16 patients (40.0%) were positive for occult blood and showed that urinary white blood cell was elevated. Of the 40 patients, 33 were newly diagnosed and 7 had a relapse. The average follow-up time was (37.4±11.9) months after combined therapy and no recurrence was found in any patients. Conclusions: Conjunctival papilloma is usually observed in people aged from 20 to 40 years and older than 50 years, and it often occurs in one eye. Its main pathological feature is benign tumors of the papillary hyperplasia on the conjunctival epithelial tissue. Some patients have atypical hyperplasia of squamous cells. The cause of the disease may be related to the infection of HPV and the urinary tract. Combined treatment can reduce the recurrence rate of conjunctival papilloma.

Abstract
Objective: To analyze the clinical characteristics of IgG4-related disease (IgG4-RD)so as to improve the understanding of IgG4-RD in China. Methods: IgG4-RD patients were recruited from Peking Union Medical College Hospital between January 2011 and January 2016. All patients were followed-up for more than 6 months. The demographic characteristics, symptoms, organ involvements, laboratory examinations and treatment efficacy were evaluated and analyzed. Results: A total of 346 patients were finally enrolled, including 230 males (66.5%) and 116 females (33.5%). The mean age of disease onset was (53.8±14.2) years old. The mostly common involved organs were lymph nodes (56.4%) and submandibular glands (52.6%). Other affected organs and manifestations included: swelling of the lacrimal glands (46.5%), autoimmune pancreatitis (38.4%), pulmonary involvement (28.0%), sclerosing cholangitis (25.4%), naso-sinusitis (23.4%), parotid gland swelling (21.7%), retroperitoneal fibrosis (19.9%), large arteries involvement (9.5%), kidney involvement (obstructive nephropathy caused by retroperitoneal fibrosis was excluded) (6.9%), skin lesions (6.4%). Rare features consisted of thyroid glands, pituitary glands, gastrointestinal tract, pachymeningitis, pericardium, sclerosing mediastinitis and orchitis. The majority of patients had multi-organ involvement, such as 74.3% patients with 3 and more, 18.2% and 7.5% patients with 2 and single organ involvement respectively. The average IgG4-RD responder index (IgG4-RD RI) was 13.21±5.70. History of allergy was found in 172 (49.7%) patients. As to the laboratory tests, elevated serum IgG4 levels were confirmed in 285 (94.1%) patients, which was positively correlated with IgG4-RD RI. There were 33.5% patients receiving monotherapy of glucocorticoid, 52.6% treated with glucocorticoids combined with immunosuppressive agents, 4.9% patients with immunosuppressant only, and 9.0% patients with mild disease not receiving medication. The majority (336, 97.1%) patients improved the above regimens. Conclusion: IgG4-RD is a systemic fibro-inflammatory disease with multiple organ involvement. The mostly common involved organs include lymph node, submandibular glands, and pancreas. Glucocorticoids and immunosuppressive agents were effective for IgG4-RD.

Abstract
Propofol, an intravenous anesthetic agent widely used in clinical practice, is the preferred anesthetic for asthmatic patients. This study was designed to determine the protective effect and underlying mechanisms of propofol on airway inflammation in a mast cell-dependent mouse model of allergic asthma. Mice were sensitized by ovalbumin (OVA) without alum and challenged with OVA three times. Propofol was given intraperitoneally 0.5 h prior to OVA challenge. The inflammatory cell count and production of cytokines in the bronchoalveolar lavage fluid (BALF) were detected. The changes of lung histology and key molecules of the toll-like receptor 4 (TLR4)/reactive oxygen species (ROS)/NF-κB signaling pathway were also measured. The results showed that propofol significantly decreased the number of eosinophils and the levels of IL-4, IL-5, IL-6, IL-13, and TNF-α in BALF. Furthermore, propofol significantly attenuated airway inflammation, as characterized by fewer infiltrating inflammatory cells and decreased mucus production and goblet cell hyperplasia. Meanwhile, the expression of TLR4, and its downstream signaling adaptor molecules--myeloid differentiation factor 88 (MyD88) and NF-κB, were inhibited by propofol. The hydrogen peroxide and methane dicarboxylic aldehyde levels were decreased by propofol, and the superoxide dismutase activity was increased in propofol treatment group. These findings indicate that propofol may attenuate airway inflammation by inhibiting the TLR4/MyD88/ROS/NF-κB signaling pathway in a mast cell-dependent mouse model of allergic asthma.

Abstract
BACKGROUND/AIMS Micro RNAs (miRNAs) play a very important role in myocardial ischemia/ reperfusion injury (MIRI), including in inflammation, apoptosis, and angiogenesis. Previous studies have demonstrated up-regulation of miR-327 in renal ischemia/reperfusion injury and MIRI. Via TargetScan, we found RP105 is a possible target gene of miR-327; our previous studies have also confirmed that RP105 acted as a cardioprotective protein in MIRI by reducing inflammation. However, the regulatory effect of miR-327 on RP105 has not previously been proposed. In our study, we aimed to identify the regulatory effect of miR-327 on RP105 protein in MIRI rats. METHODS Sixty male Sprague-Dawley rats were randomly divided into five groups, which were pre-treated with saline (sham and ischemia/reperfusion group), adenovirus-expressing miR-327-RNAi (Ad-miR-327-i group), control (Ad-NC group), or pri-miR-327 (Ad-miR-327 group) treatments. Three days later, the rat MIRI model was established by ischemia for 30 min, followed by reperfusion for 3 h. Myocardium and plasma were harvested and assessed. RESULTS miR-327 was increased by nearly 3-fold both in myocardium and plasma, which down-regulated RP105 in a 3'-untranslated region-dependent manner, and down-regulation of miR-327 via adenovirus transfection indirectly suppressed the TLR4/ TLR2-MyD88-NF-κB signaling axis activation via up-regulation of RP105, which subsequently resulted in reduced myocardial infarct size, attenuated cardiomyocyte destruction, and alleviated inflammation. In contrast, up-regulation of miR-327 induced the opposite effect. CONCLUSION Down-regulation of miR-327 exerts a cardioprotective effect against MIRI by reducing inflammation, which may constitute a promising molecular therapeutic target for treating MIRI.

Abstract
Objective:To study the risk factors of recurrence in patients with benign paroxysmal positional vertigo(BPPV) after successful repositioning treatment. Method: Two hundred and two cases of confirmed BPPV patients, were followed-up for 10 months after particle repositioning, and the incidence of recurrence was analyzed. The risk factors for recurrence were analyzed by logistic regression. Result: 51 out of 202 confirmed BPPV patients complained of recurrence. There was significant difference of the duration of vertigo before treatment, the times of repositioning and SDS between the two group(P<0.05). While the sex, the age, the incubation period of BPPV, the duration time of BPPV, underlying diseases and the type of canal were not associated with the residual dizziness(P>0.05). Logistic regression analysis showed that the times of repositioning and the SDS were the risk factor for residual dizziness. Conclusion:The effective repositioning and the psychological care are very important to reduce the recurrence of BPPV.

Abstract
OBJECTIVE The aim of this study was to compare the effects of adjuvant chemoradiotherapy (CRT) and adjuvant chemotherapy (ChT) on the survival of locally advanced gastric cancer (LAGC) patients treated with R1 resection. METHODS The patients with LAGC and microscopically positive margins after a potentially curative gastrectomy in Fudan University Shanghai Cancer Centre were retrospectively identified. The patients who were referred to our hospital for adjuvant CRT after an R1 resection elsewhere were also included. The patients were divided into either the CRT group or ChT group according to the treatment strategy. We, then, examined the patient survival results and patterns of recurrence for each group. RESULTS There were 114 LAGC patients treated with an R1 resection identified (CRT, n = 33; ChT, n = 81). The baseline characteristics between the two groups were not different. The estimated 3 year recurrence-free survival and overall survival in the CRT and ChT groups were 45.1% vs 31.8% (p = 0.09) and 49.6% vs 39.4% (p = 0.20), respectively. The results indicated that only nodal status was an independent prognostic factor (hazard ratio 4.04, 95% confidence interval 2.06-7.93). The risk of locoregional recurrence was increased in the ChT group. The subgroup analysis revealed that patients with pN0-2 GC showed a better recurrence-free survival due to adjuvant CRT (hazard ratio 0.19, 95% confidence interval 0.04-0.90; p = 0.022). CONCLUSION Adjuvant CRT improves locoregional control and may benefit patients with pN0-2 GC after R1 resection. The nodal status may be the most important predictor for patient selection. Advances in knowledge: Nodal status may be the most important predictor for patient selection. Compared with adjuvant ChT, LAGC patients with pN0-2 disease may further benefit from additional radiotherapy after R1 resection.

Abstract
C-terminal binding protein-2 (CtBP2), a transcriptional corepressor, has been reported to correlate with tumorigenesis and progression and predict a poor prognosis in several human cancers. However, few studies on CtBP2 in gastric cancer (GC) have been performed. In this research, we evaluated the correlations between CtBP2 expression and the clinicopathological characteristics, as well as prognosis of GC patients. The effects of silencing CtBP2 expression on GC cells biology activity were also assessed. The results showed that CtBP2 was overexpressed in GC tissues and closely correlated with poor differentiation, advanced tumor stage and poor prognosis in GC patients. CtBP2 induced epithelial-to-mesenchymal transition (EMT) and repressed PTEN to increase proliferation rate, migration, and invasion in GC cells. Silencing CtBP2 inhibited GC growth in nude mice model. In conclusion, CtBP2 is overexpressed in GC and may accelerate GC tumorigenesis and metastasis, which could represent an independent prognostic marker and promising therapeutic target for GC.

Abstract
Background To compare the diagnostic yield and safety of 22G endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) in the diagnosis of pancreatic solid lesions. Methods Between April 2014 and September 2015, 36 patients with pancreatic solid lesions were included for endoscopic ultrasound test. Patients were randomly divided into two groups: EUS-FNA (n = 18) and EUS-FNB (n = 18). Each nidus was punctured three times (15 ~ 20 insertions for each puncture) with a 22G needle. The core specimens were analyzed, and the diagnostic yields of FNA and FNB were evaluated. Results The procedure success rate was 100% with no complications. Cytological and histological examinations found that the diagnostic yield of FNB and FNA were both 83.3%. To get a definitive diagnosis, FNB needed fewer punctures than FNA (1.11 vs. 1.83; P < 0.05). Conclusions 22G EUS-FNB is a safe and effective way to diagnose pancreatic solid lesions. FNB required a lower number of needle passes to achieve a diagnosis compared with FNA.

Abstract
Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69). The baseline characteristics, disease status, other history of surgery and echocardiography parameters before and after septal reduction were collected, as well as the complication within 1 week after operation. Results: The mean age in surgery group was (46±14) years old, with 76 males (56.3%); mean age was (47±11) years old and with 51 males (73.9%) in PTMSA group. There was no significant difference in age, gender, the time of symptom and diagnosis, syncope, family history and atrial fibrillation between the two groups (all P>0.05). The proportion of mitral valve prolapse in the surgery group was higher than that in PTMSA group (75.8% vs 44.2%, P<0.05). Baseline left ventricular outflow tract (LVOT) gradient was comparable (82.7 mmHg in surgery group vs 77.7 mmHg in PTMSA group, P>0.05). The mean resting LVOT gradient after septal reduction therapy was lower (16.55 mmHg in surgery group, 26.68mmHg in PTMSA group) than that before operation, with lower gradient in surgery group (P<0.05). Compared with PTMSA group, the duration of hospitalization was longer in surgery group (P<0.05). There was similar rate of operation related complications in the two groups. Conclusions: Both septal reduction therapies can improve the LVOT obstruction, more significant in surgery group, but with longer hospital stay. The rate of operation related complication is similar in both groups.

Abstract
Objective: To investigate the possible role of IL17-and IL22-secreting cells combined with patch test for the prediction of formaldehyde-induced occupational allergic contact dermatitis(OACD). Methods: From October 2014 to October 2016, totally 131 formaldehyde-exposed workers(49 cases with inflammatory skin lesions,82 ones without inflammatory skin lesions)and 63 non-exposed health controls were recruited. Patch-test was performed in 49 cases of formaldehyde-exposed workers with inflammatory skin lesions. Circulating IL17+and IL22+Tcell subsets were assessed by flow cytometry(FCM). Results: Among 49 cases of formaldehyde-exposed workers with inflammatory skin lesions,32 cases were with positive patch-test while 17 cases with negative patch-test. The proportions of circulating CD3+CD8-IL17+ and CD3+CD8-IL22+ cells from patch-test(+) formaldehyde-exposed workers were significantly higher than that of patch-test(-)group, formaldehyde-exposed workers without skin lesions and non-exposed controls(P<0.05). The proportions of circulating CD3+CD8-IL17+ and CD3+CD8-IL22+cells from patch-test(-)group and formaldehyde-exposed workers without skin lesions were also higher than that of non-exposed controls(P<0.05). But there was no significant difference between patch-test(-)group and formaldehyde-exposed workers without skin lesions(P>0.05). Peripheral CD3+CD8+IL17+and CD3+CD8+IL22+cells were also detected in spite of small amounts. The percentages of CD3+CD8+IL17+and CD3+CD8+IL22+ cells inperipheral blood from patch-test(+)formaldehyde-exposed workers were enhanced significantly, compared to patch-test(-)group, formaldehyde-exposed workers without skin lesions and non-exposed controls(P<0.05). The proportions of circulating CD3+CD8+IL17+ and CD3+CD8+IL22+ cells from patch-test(-)group and formaldehyde-exposed workers without skin lesions were significantly higher than that of non-exposed controls(P<0.05). But there was no significant difference between patch-test(-) group and formaldehyde-exposed workers without skin lesions(P>0.05). Conclusion: The proportions of circulating IL17+ and IL22+T cells(both CD8-and CD8+)are enhanced in formaldehyde-exposed workers at proposed OEL, possibly involved in the development of formaldehyde-induced OACD.The detection of IL17-and IL22-secreting cells combined with formaldehyde patch test help to screen the workers with allergy property and prevent OACD.

Abstract
The aim of this study was to investigate the mechanism of propranolol on the regression of hemangiomas. Propranolol-treated hemangioma tissues were collected and the expression of hypoxia inducible factor-1α (HIF-1α) was examined. We also established HIF-1α overexpression and knockdown hemangioma cells, and determined the effects of HIF-1α on the hemangioma cells proliferation, apoptosis, migration and tube formation. Significantly increased HIF-1α level was found in the hemangioma tissues compared to that in normal vascular tissues, whereas propranolol treatment decreased the HIF-1α level in hemangioma tissues in a time- and dose-dependent manner. Moreover, propranolol treatment significantly decreased cell proliferation, migration and tube formation as well as promoted cell apoptosis in HIF-1α overexpression and knockdown hemangioma cells. Propranolol suppressed the cells proliferation, migration and tube formation of hemangioma cells through HIF-1α dependent mechanisms. HIF-1α could serve as a novel target in the treatment of hemangiomas.

Abstract
Objective: To investigate the prevalence and treatment effects of Demodex species in eyelash follicles in patients with meibomian gland dysfunction (MGD). Methods: The MGD patients (MGD group) and normal subjects (control group) were collected from the Ophthalmology Clinic in PUMCH from July 2015 to December 2015. The symptom score of MGD patients was recorded. Eyelash sampling, Demodex counting, tear film break-up time (BUT), cornea fluorescein staining (Fl) and Schirmer test Ia (S Ⅰ aT) were measured for both groups. All the measurements were repeated after 4 weeks of meibomian function treatment for the MGD group. Symptom score, BUT, Fl and S ⅠaT were normally distributed and displayed as mean± standard deviation. Demodex counting was not normally distributed and displayed as median (interquartile range P25, P75). Results: Forty-four MGD patients (88 eyes) and 48 controls (96 eyes) were recruited. For the MGD and control groups, the number of Demodex was 3.5 (2, 7) and 0 (0, 7), respectively (Z =-4.912,P= 0.000). The percentage of Demodex infestation was 86.4% and 39.6%, respectively (χ(2)=35.957, P=0.000). The BUT was (3.57±2.09) s and (10.17±3.25) s, respectively (t=-5.154, P=0.000). The Fl was 2.73±1.23 and 0.85± 0.33, respectively (t=4.583, P=0.000). The SⅠaT was (8.75±5.61) s and (14.51±5.29) s, respectively (t=-2.278, P=0.028). The symptom score of the MGD group before and after treatment was 4.77 ± 3.01 and 2.79 ± 2.01, respectively (t=6.224, P=0.000). The BUT, Fl and number of Demodex of the MGD group after the treatment were (5.43±2.37)s, (1.91±0.66) and 2 (0, 3), respectively, and all had significant difference with the data before the treatment (BUT, t=-4.705, P=0.000. Fl, t =3.902, P =0.000. number of Demodex, Z=-4.623, P =0.000). The S Ⅰ aT of the MGD group after the treatment was 8.86 ± 6.76, with no significant difference with the data before the treatment (t=-0.277, P=0.833). Conclusions: The Demodex infestation has some effects on the pathogenesis of MGD. The treatment of MGD may help to decrease the number of Demodex and thus relieve the ocular discomfort.(Chin J Ophthalmol, 2017, 53:193-197).

Abstract
Understanding and managing pollination service is hindered by taxonomic impediments and paucity of data, particularly in the tropics. Herein we apply integrative species delineation and taxonomy to test impacts of land use on the diversity of bee communities within Xishuangbanna (Yunnan, south China), a highly biodiverse tropical region which has undergone extensive land conversion to rubber plantation. 128 Operational Taxonomic Units (OTU) were inferred by an iterative and integrative approach. Bee activity differed significantly across land use samples, although community composition corresponded more to level of vegetation density, when accounting for spatial structure. Species diversity was high in young rubber plantations, although composition overlapped with other species-rich habitats (natural forest edge and river banks), and older plantations (>8 years) showed very low diversity under all measures. Community structures were similar between the natural forest interior and edge, although analysis indicated contrasting drivers of diversity, with clustering in the interior and overdispersion in the forest edge. Further, phylogenetic diversity and derived indices were underestimated when reference data were omitted from analysis. The description of bee communities herein permits more informed choices in land management with respect to ensuring continuation of essential services by bees.

Abstract
Objective: To investigate the prevalence, severity of hearing disorders and demographics of people with hearing disorders based on the whole population in Jilin, Guangdong, Shannxi and Gansu provinces in China. Methods: According to " WHO Ear and Hearing Disorders Survey Protocol" , 144 clusters were chosen with probability proportional sampling(PPS) method from the four provinces covering 194, 688, 061 residents. Audiological test, otological examination and questionnaire surveying were conducted for all samples from August, 2014 to September, 2015. The hearing disorders were classified according to WHO criteria and classification. Results: Among 47 511 targeted residents, 45, 052 individuals (94.82% response rate) participated in the survey. The standardized prevalence rates of hearing disorders and disabling hearing disorders were 15.84 % and 5.17 % respectively. Almost 50% of people with hearing disorders had no awareness of it or its starting time. There was significant difference in the prevalence among people of different ages, genders, occupations, provinces, marital status and education levels. The prevalence of hearing disorders increased significantly as age grew. People above 60 years old occupied 55.31% of the total hearing disorders. The prevalence of hearing disorders among male, people of low education and those who lost husband or wife, as well as workers and farmers was relatively higher. Conclusions: The prevalence of hearing disorders is high, and hearing disorders are " invisible" . Demographics and socioeconomic factors significantly influence the prevalence of hearing disorders.
