Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Patients with atrial fibrillation complicated with kidney disease have a high risk of stroke and bleeding, and have some limitations or contraindications to oral anticoagulants. Left atrial appendage closure has been used as an alternative to oral anticoagulation in patients with atrial fibrillation, but its efficacy and safety in patients with atrial fibrillation and chronic kidney disease need to be further confirmed. This paper intends to review the research progress of left atrial appendage occlusion in patients with atrial fibrillation complicated with chronic renal insufficiency.

Objective: To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with programmed death-1 (PD-1) antibody in operable, borderline or potentially resectable locally advanced esophageal squamous cell carcinoma(ESCC) in the real world. Methods: The study retrospectively analyzed 28 patients with operable or potentially resectable locally advanced ESCC patients treated with preoperative chemotherapy combined with PD-1 inhibitor in Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from April 2020 to March 2021. According to the clinical TNM staging system of the 8th edition of the American Joint Committee on Cancer, there were 1, 15, 10, 1 and 1 case of stage Ⅱ, Ⅲ, ⅣA, ⅣB and unknown stage respectively. The treatment was two cycle of dual drug chemotherapy regimen including taxane plus platinum or fluorouracil combined with PD-1 antibody followed by tumor response assessment and surgery if the patient was eligible for resection. Results: Of the 28 patients, 1, 2, 3 and 4 cycles of chemotherapy combined with PD-1 antibody treatment completed in 1, 21, 5, and 1 patient, respectively. Objective response rate (ORR) was 71.4% (20/28), and disease control rate (DCR) was 100% (28/28). The incidence of adverse events exceeding grade 3 levels was 21.4% (6/28), including 3 neutropenia, 1 leukopenia, 1 thrombocytopenia and 1 immune hepatitis. There was no treatment-related death. Of the 23 patients underwent surgery, R0 resection rate was 87.0% (20/23), 13 patients had down staged to the T1-2N0M0 I stage, the pCR rate was 17.3% (4/23), and the pCR rate of primary tumor was 21.7% (5/23). Four patients received definitive chemoradiotherapy. One patient rejected surgery and other treatment after achieved PR response.

Abstract: Objective　To analyze the distribution and drug resistance evolution characteristics of pathogenic bacteria of bloodstream infection in nine tertiary hospitals in Yunnan Province from 2017 to 2021, so as to provide reliable basis for rational selection of antibiotics in clinic. Methods Using the drug sensitive paper method or instrument method, the bacteria identification and drug sensitivity test were carried out in nine tertiary hospitals in different regions according to the unified technical scheme. The results were judged according to the Clinical and Laboratory Standards Institute (CLSI) breakpoint standard in 2021, and use WHONET5.6 for data statistical analysis. Results A total of 12 003 strains of pathogenic bacteria were isolated from bloodstream infection samples in the past five years, including 7 442 strains of Gram-negative bacteria (62.0%) and 4562 strains of Gram-positive bacteria (38.0%), with an increasing trend in the number of isolated strains; of these, 163 strains (1.4%) were isolated from outpatients and 11 840 strains (98.6%) were isolated from inpatients. The top three gram-negative bacteria were Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, of which 309 strains (4.2%) were carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 29 strains (0.4%) carbapenem-resistant Escherichia coli and 19 strains (0.3%) carbapenem-resistant Enterobacter cloacae, and the number of CR-KPN was on the rise year by year. The top three Gram-positive bacteria were coagulase-negative staphylococci, Staphylococcus aureus and Enterococcus faecium, of which methicillin-resistant Staphylococcus aureus (MRSA) was detected for 213 strains, accounting for 27.7%, and decreased from 40.0% in 2017 to 23.4% in 2021, showing a downward trend year by year. No vancomycin-resistant staphylococci and enterococci were found. Conclusions The detection and composition of bloodstream infection pathogenic bacteria in multicenter have not changed much in the past five years, but each hospital has its own characteristics. The number of carbapenem resistant Enterobacteriaceae increased year by year, which should be paid more attention.

Objective To investigate the expression and the potential roles of long non-coding RNA(lncRNA)cancer susceptibility candidate 2(CASC2)and imprinted gene H19 in extrahepatic cholangiocarcinoma(ECC). Methods Four samples from patients with ECC were collected for high-throughput sequencing which was conducted to reveal the transcriptomic profiles of lncRNA CASC2 and H19.Bioinformatics tools were employed to predict the potential roles of the two genes.Another 22 ECC tissue samples and the cholangiocarcinoma cell lines(RBE,QBC939,HuH-28,and HuCCT1)with different degrees of differentiation were selected for validation.The para-carcinoma tissue and normal human intrahepatic biliary epithelial cell(HIBEC)were used as the control groups.The expression levels of lncRNA CASC2 and H19 in carcinoma tissue,para-carcinoma tissue,and cell lines were determined by real-time quantitative polymerase chain reaction(qRT-PCR).The correlation analysis was carried out for the clinical indicators of patients with the expression levels of the target genes. Results The two target genes showed significantly different expression between carcinoma tissue and para-carcinoma tissue(all P<0.05).Specifically,CASC2 had higher expression level in the carcinoma tissue than in the para-carcinoma tissue(t=1.262,P=0.025),whereas the expression of H19 showed an opposite trend(t=1.285,P=0.005).The expression levels of CASC2 in QBC939(t=8.114,P=0.015)and HuH-28(t=9.202,P=0.012)cells were significantly higher than that in the control group.The expression levels of H19 were significantly lower in RBE(t=-10.244,P<0.001),QBC939(t=-10.476,P<0.001),HuH-28(t=-19.798,P<0.001),and HuCCT1(t=-16.193,P=0.004)cells than in the control group.Bioinformatics analysis showed that CASC2 was mainly involved in the metabolic process and H19 in the development of multicellular organisms.Both CASC2 and H19 were related to catalytic activity.The expression level of lncRNA CASC2 was correlated with pathological differentiation(χ ²=6.222,P=0.022)and lymph node metastasis(χ²=5.455,P=0.020),and that of lncRNA H19 with pathological differentiation(χ²=1.174,P=0.029)and tumor size(χ²=-0.507,P=0.037). Conclusions In the case of ECC,lncRNA CASC2 and H19 have transcription disorders.lncRNA CASC2 is generally up-regulated in the carcinoma tissue,while H19 is down-regulated.Both genes have the potential to become new molecular markers for ECC.

OBJECTIVE: To explore the influencing factors of low back pain and the relationship of the influence of bad working posture, weight load and frequency of load and the dose-response relationship among the occupational workers of key industries in China. METHODS: A total of 57 501 employees from 15 key industries in China were selected as research subjects using stratified cluster sampling method. The occurrence of low back pain in the past one year, as well as occupational factors such as job type, labor organization and work posture were investigated by using the Chinese version Musculoskeletal Disorders Questionnaire. RESULTS: The prevalence of low back pain in the occupational population of key industries in China was 16.4%(9 448/57 501). Multivariate Logistic regression analysis showed that the risk of low back pain in females was higher than that in males(P<0.01). Married, obese, occasional and frequent smokers, and a history of lower back disease were associated with increased risk of low back pain(all P<0.05). The risk of low back pain was associated with older age, higher education level, and lower frequency of physical exercise(all P<0.01). The risk of low back pain was higher with longer working time, greater back curvature, and the high frequency of long standing and sitting position work, uncomfortable working posture, repeated operation per minute, and lifting>5 kg weight(all P<0.01). CONCLUSION: The influencing factors of low back pain in the occupational population of key industries in China include bad working posture, high frequency load, weight load and other individual factors. There is a dose-response relationship with low back posture load and frequency of load.
