Objective To analyze the clinical data of patients undergoing emergency operation for small intestinal perforation secondary to small intestinal metastasis of lung cancer and explore the clinical characteristics,treatment strategies,and preventive measures.Methods The clinical data of 11 patients who underwent emergency operation for small intestinal perforation secondary to small intestinal metastasis of lung cancer at the Department of Emergency Surgery,Zhongshan Hospital,Fudan University from Jan 2018 to Jun 2023 were selected for retrospective analysis.Analysis factors included age,gender,clinical manifestations,comorbidities,past history,preoperative imaging results,preoperative blood test results,treatment,surgical methods,metastasis sites,perforation sites,pathological types,hospitalization time,and prognostic outcomes.Results All of the 11 patients went to the emergency room with abdominal pain,and their duration of abdominal pain ranged from 8 to 96 hours.There were white blood cells≥9.5×109/L in 10 patients,neutrophil percentages≥90%in 8 patients,procalcitonin(PCT)≥0.05 ng/mL in 10 patients,and C-reactive protein(CRP)≥5 mg/L in 11 patients.Among the 11 patients,7 cases had jejunal perforation and 4 cases had ileal perforation;10 patients underwent partial small bowel resection and enter-enterostomy,and 1 patient underwent small bowel perforation repairment and jejunostomy;10 patients were receiving anti-tumor drug treatment before operation,of which 7 patients received targeted therapy alone,2 patients received chemotherapy alone,and 1 patient received both targeted therapy and chemotherapy.Postoperative hospitalization time ranged from 4 to 71 days,of which 3 patients died and 8 patients were discharged successfully.Conclusion Jejunum is the main perforation site of small intestinal perforation secondary to small intestinal metastasis of lung cancer.Patients with advanced lung cancer should have regular comprehensive examinations to detect distant metastases early.Early detection enables timely intervention,which can help prevent serious complications.

Objective:To investigate the incidence and influencing factors of allergic reactions to cephalosporins.Methods:A cross-sectional study of 29 medical institutions in Zhejiang Province was conducted from April 2021 to June 2021.The incidence of allergic reactions to cephalosporins was investigated,and the influencing factors of cephalosporin-induced allergic reactions were analyzed by Poisson regression.Results:A total of 56 155 patients were included in this study.The total incidence of allergic reactions to cephalosporin was 1.67‰,the highest incidence of anaphylaxis occurred for ceftizoxime(4.27‰),followed by ceftriaxone(3.49‰)and cefotaxime(2.40‰).There was no significant difference in the incidence of allergic reactions between patients with negative skin tests and those without skin tests(1.75％o vs.1.63‰,RR=1.07,95％CI:0.70-1.63,P＞0.05).Poisson regression showed that body mass index(BMI)＜18.5 kg/m2(RR=2.43,95％CI:1.23-4.82,P＜0.05)and history of β-lactam antibiotics allergy(RR=33.88,95％CI:1.47-781.12,P＜0.05)increased cephalosporin-induced anaphylaxis.Compared with cefuroxime,the risk of allergic reactions was increased for ceftriaxone(RR=3.08,95％CI:1.70-5.59,P＜0.01),ceftazidime(RR=1.89,95％CI:1.03-3.47,P＜0.05),and ceftizoxime(RR=3.74,95％CI:1.64-8.50,P＜0.01).Conclusions:Lower BMI and history of β-lactam antibiotics allergy increase the risk of cephalosporin allergic reactions.The routine skin test may not reduce the occurrence of allergic reactions to cephalosporins. This study has been registered at Chinese Clinical Trial Registry(ChiCTR2200064314).

Objective To investigate the relationship between single nucleotide polymorphisms(SNPs)in the eNOS gene and genetic susceptibility to systemic lupus erythematosus(SLE)in Hainan.Methods Blood samples were collected from SLE patients(SLE group,n=214)and healthy controls(control group,n=214)from January 2020 to December 2022 at the First Affiliated Hospital of Hainan Medical College and Hainan Provincial People's Hospital.The bases of eNOS gene rs3918188,rs1799983 and rs1007311 loci in each group were detected by SNaPshot sequencing technology.Logistic regression was used to analyze the correlation between genotypes,alleles and gene models(dominant model,recessive model,and overdominant model)of the above 3 target loci of the eNOS gene and genetic susceptibility to SLE.Haplotype analysis was conducted using HaploView 4.2 software to investigate the relationship between haploid and genetic susceptibility to SLE at each site.Results The results of logistic regression analysis revealed that the CC genotype and the C allele at rs3918188 locus were risk factors for genetic susceptibility to SLE(CC vs.AA:OR=2.449,P<0.05;C vs.A:OR=2.133,P<0.001).In recessive model at rs3918188 locus,CC genotype carriers had an increased risk of SLE development compared with AA+AC genotype carriers(OR=2.774,P<0.001).In contrast,in overdominant model at this locus,AC genotype carriers had a decreased risk of SLE occurrence compared with AA+CC genotype carriers(OR=0.385,P<0.001).In addition,polymorphisms of rs1799983 and rs1007311 were not associated with susceptibility to SLE in genotype,allele type and the 3 genetic models(P>0.05).Haplotype analysis revealed a strong linkage disequilibrium between the rs1007311 and rs1799983 loci of the eNOS gene,but no significant correlation was found between haplotype and genetic susceptibility to SLE(P>0.05).Conclusion The CC genotype and C allele at rs3918188 locus of eNOS gene may be risk factors for SLE in Hainan,while the risk of SLE occurrence is reduced in carriers of AC genotype under the overdominant model.

Objective To investigate the neuroprotective effect and potential mechanism of rehabilitation training combined with citicoline on cerebral hemorrhage model in mice based on Keap1/Nrf2/ARE signaling pathway.Methods The C57BL/6 male mice were randomly divided into sham operation group(sham operation treatment),model group(right caudate putamen hemorrhage model induced by type Ⅶcollagenase),choline group(model+choline 64 mg·kg-1),rehabilitation training group(rehabilitation training)and combined group(model+rehabilitation training+choline 64 mg·kg-1).The study observed the modified neurological severity score(mNSS)in mice with cerebral hemorrhage;colorimetric assays were used to detect the expression of malondialdehyde(MDA),superoxide dismutase(SOD)and catalase(CAT)in brain tissues;protein imprinting and reverse transcription-quantitative polymerase chain reaction were employed to assess the expression of Kelch-like ECH-associated protein 1(Keap1),nuclear factor erythroid 2-related factor 2(Nrf2)/antioxidant response element(ARE),heme oxygenase-1(HO-1),quinone oxidoreductase 1(NQ01)proteins and mRNA in brain tissues.Results The mNSS scores of sham operation group,model group,citicoline group,rehabilitation training group and combined group were 0,1.56±0.73,1.00±0.00,0.78±0.44 and 0.67±0.50;the MDA contents were(6.93±0.92),(22.97±0.77),(19.26±1.73),(13.21±0.78)and(7.25±0.97)nmol·mgprot-1;the relative expression of Keap1 protein were 0.79±0.03,1.02±0.04,0.95±0.10,0.90±0.09 and 0.86±0.05;the relative expression levels of Nrf2 protein were 0.94±0.12,0.71±0.08,0.90±0.07,0.98±0.12 and 1.33±0.25.There were significant differences in the above indexes between the model group and the sham operation group(P＜0.05,P＜0.01);there were significant differences between the citicoline group and the rehabilitation training group,the model group(P＜0.05,P＜0.01);there were significant differences between the combined group and the citicoline group,the rehabilitation training group except for protein expression of Keap1(all P＜0.01).Conclusion Rehabilitation training and citicoline can reduce the symptoms of neurological deficits in mice with cerebral hemorrhage.The mechanism way be that they can activate the Keap1/Nrf2/ARE signaling pathway to exert anti-oxidative stress,and the combined effect is the best.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To investigate the effects of high-risk human papillomavirus 16 E6 protein(HPV16 E6 protein)on invasion and migration of cervical cancer SiHa cells via regulating the expression of expression miR-23a.Methods Tissue samples from 100 patients with cervical cancer HPV-negative,100 HPV-positive patients,and 100 paracancerous normal tissues were collected;cervical cancer SiHa cells were divided into blank group,E6 overexpression group,negative transfection group,and E6 + miR-23a mimics group.The expression of miR-23a and HPV16 E6 mRNA were detected by qRT-PCR;MTT assay was used to detect the cell proliferation inhibition rate;flow cytometry to detect the apoptosis;Transwell chamber assay to detect cell invasion,and scratch test to detect the ability of cell migration.The expression of HPV16 E6,apoptosis related proteins(Caspase-3,Bax,Bcl-2),and migration related proteins(MMP-2,MMP-9)was detected by WB.Results The expression level of miR-23a was decreased in cervical cancer tissues,and that was lower in HPV positive cervical cancer tissues.Overexpression of E6 decreased the expression level of miR-23a,cell proliferation inhibition rate,apoptosis rate,Caspase-3 and Bax protein expression,and increased the expression of Bcl-2 protein,scratch healing rate,inva-sion cell number,MMP-2,MMP-9 protein expression(P<0.05);miR-23a mimics reversed the effects of E6 overexpression on the above indicators.Conclusion HPV16 E6 promotes the invasion and migration of cervical cancer cells,which may be related to the regulation of miR-23a expression.
