Objective The aim of this study was to analyze the incidence and mortality of esophageal cancer and its trend in Lianyungang city from 2008 to 2019.Methods The data of esophageal cancer in all cancer registry areas in Lianyungang city were col-lected and sorted out,and the quality control reached the standards.The incidence,mortality,age-standardized rate of Chinese population(ASRC),age-standardized rate of World population(ASRW),cumulative rate at 0-74 years old,truncation rate of 35-64 years old,and composition ranking were calculated.The Joinpoint4.7.0.0software was used to analyze the average annual percentage change(AAPC)of the age-standardized incidence and mortality of esophageal cancer by the standard population(ASIRC and ASMRC).Results From 2008 to 2019,the incidence of esophageal cancer in Lianyungang city was 25.90/100,000,ASIRC was 17.95/100,000,ASIRW was 17.91/100,000,ranking the third in the incidence spectrum of malignant tumors.The mortality was 20.55/100,000,ASMRC was 13.86/100,000,and ASMRW was 13.71/100,000,ranking the third in the malignant tumor mortality spectrum.The incidence,mortali-ty,ASIRC and ASMRC of esophageal cancer were higher in men than those in women,and higher in rural areas than those in urban are-as.From 2008 to 2019,the change trend of incidence and mortality of esophageal cancer in Lianyungang city was the same,showing a downward trend.The AAPC of the ASIRC was-6.19%(95%CI:-7.08%-5.30%,P<0.001),and the AAPC of the ASMRC was-4.03%(95%CI:-5.81%-2.22%,P<0.001).Among them,the ASIRC and ASMRC of esophageal cancer in urban and rural areas showed a downward trend(P<0.05).Among them,the ASIRC and ASMRC of esophageal cancer in urban women decreased the most,with an average annual decline of-7.99%(95%CI:-10.86%-5.03%,P<0.001)and-9.19%(95%CI:-12.35%-5.93%,P<0.001).Conclusion The incidence and mortality of esophageal cancer in Lianyungang city have shown a downward trend,a rural areas and male populations are the key prevention and control populations for esophageal cancer.

This study investigated the full-genome molecular characteristics of a rotavirus vaccine-derived strain,G1P[8]geno-type A group rotavirus RVA/Human-wt/CHN/HN1140/2021/G1P[8](referred to as HN1140).The gene fragments of the HN1140 strain were amplified with reverse transcription-polymerase chain reaction(RT-PCR)combined with whole-genome primers to obtain the full genome sequence.Genotyping was performed with the online genotyping tool RotaC 2.0,and similarity and genetic evolution analyses for each gene segment were conducted in DNAstar5.1 and MEGA11.0 software.The genotype of the HN1140 strain was deter-mined to be G1-P[8]-I2-R2-C2-M2-A3-N2-T6-E2-H3.Phylogenetic analysis demonstrated that all 11 genomic segments clus-tered closely with the RotaTeq vaccine strains,sharing 99.7%-100%nucleotide sequence similarity.Notably,VP1,VP2,VP6,and NSP2-NSP5 segments showed 100%nucleotide identity with RotaTeq strains.Comparative genomic analysis identified 13 nucleotide and 8 amino acid substitutions between HN1140 and RotaTeq strains,localized within the VP7,VP4,VP1,VP2,VP3,and NSP1 segments.The HN1140 strain exhibited the genotype G1-P[8]-A3-T6-H3,which was consistent with the typical profile of a vaccine-derived reassortant.This strain demonstrated high genetic similarity to RotaTeq vaccine strains,with nucleotide sequence identity ranging from 99.7%to 100%.These findings suggested that HN1140 evolved from RotaTeq vaccine strains through genetic reassortment.

Objective To explore the application value of laparoscopic assisted ileostomy closure after prophylactic ileostomy.Methods A retrospective analysis was conducted on 63 cases of middle and low rectal cancer who received ileostomy closure after prophylactic ileostomy in natural orifice specimen extraction surgery(NOSES)from September 2017 to May 2023.Among them,31 cases underwent laparoscopic assisted ileostomy closure(observation group),and 32 cases underwent conventional open ileostomy closure(control group).The operative time,intraoperative blood loss,time to first ambulation,time to first flatus,time to first liquid diet,postoperative pain score,postoperative hospital stay time,and postoperative complications were compared between the two groups.Results All the 63 cases successfully underwent ileostomy closure.The observation group showed significantly better outcomes than the control group in operative time[(63.2±5.7)min vs.(93.5±4.7)min,t=-23.109,P=0.000],intraoperative blood loss[7.0(6.0,8.0)ml vs.22.5(21.0,24.0)ml,Z=-6.853,P=0.000],time to first ambulation[1.0(1.0,1.0)d vs.2.0(2.0,2.0)d,Z=-5.653,P=0.000],time to first flatus[1.0(1.0,2.0)d vs.2.0(2.0,2.0)d,Z=-5.304,P=0.000],time to first liquid diet[2.0(2.0,3.0)d vs.3.0(2.0,3.0)d,Z=-3.000,P=0.003],postoperative pain score[24 h:3.0(3.0,4.0)vs.4.0(3.0,4.0),Z=-4.501,P=0.000;48 h:2.0(2.0,2.0)vs.3.0(2.0,3.0),Z=-3.750,P=0.000;72 h:1.0(1.0,2.0)vs.2.0(2.0,2.0),Z=-2.996,P=0.003],and postoperative hospital stay[(6.8±1.6)dvs.(8.5±1.5)d,t=-4.297,P=0.000].The observation group had a lower postoperative incision infection rate than the control group[3.2％(1/31)vs.34.4％(11/32),x2=9.908,P=0.002],while no significant differences were observed in incision dehiscence,intestinal obstruction,or abdominal hemorrhage(P＞0.05).Conclusions For patients with middle and low rectal cancer who undergoing ileostomy closure after prophylactic ileostomy in NOSES,laparoscopic assisted ileostomy closure is safe and feasible.Compared with open surgery,it reduces incision infection rate,alleviates postoperative pain,shortens hospital stay,and promotes recovery.

Group C rotavirus（RVC）is one of the important etiological agents responsible for human rotavirus gastroenteritis（RVGE）. Although its overall detection rate has shown a declining trend in recent years，sporadic outbreaks continue to be reported，highlighting its potential public health threat. RVC infections predominantly occur in preschool children，adolescents，and adults，typically presenting with mild to moderate diarrhea. While most cases are sporadic，cluster outbreaks can also occur. At present，fundamental research on RVC remains limited，particularly regarding its transmission and pathogenesis. Nevertheless，emerging evidence suggests that interspecies transmission may represent a key route of human infection. This review provides a comprehensive overview of current research on RVC-associated gastroenteritis，with a particular focus on its virological characteristics，epidemiological patterns，clinical manifestations，and preventive and control strategies. It aims to offer a theoretical foundation and practical reference for future studies and public health interventions targeting RVC.

OBJECTIVE: To summarize the clinical characteristics of foot and ankle deformities combined with knee and lower limb deformities and evaluate the advantages, clinical outcomes, and considerations of QIN Sihe's surgical strategy for treating such complex deformities. METHODS: Between January 2022 and December 2024, 32 patients with foot and ankle deformities combined with knee and lower limb deformities were enrolled. The cohort included 23 males and 9 females, aged 10-67 years (mean, 41.1 years). The main etiologies included post-polio sequelae (20 cases) and congenital limb deformities (3 cases). Deformities were categorized as follows: equinovarus foot (12 cases), equinus foot (2 cases), equinovalgus foot (3 cases), equinus foot with swan-neck deformity (2 cases), calcaneus foot (5 cases), foot valgus (2 cases), knee flexion deformity (14 cases), genu recurvatum (4 cases), genu varum (3 cases), genu valgum (3 cases), lower limb shortening (3 cases), and lower limb external rotation (6 cases). QIN Sihe's surgical strategies included osteotomies, tendon releases, and tendon transfers for deformity correction, followed by external fixation for residual deformity adjustment and stabilization. Outcomes were assessed using QIN Sihe's Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction. RESULTS: All patients were followed up 8-32 months (mean, 16.5 months). Complications included pin tract infection (1 case, 1 site), ankle pain (2 cases), delayed healing at the proximal tibial osteotomy site (1 case), and anterior talar dislocation (1 case). At last follow-up, insufficient correction of foot deformity was observed in 1 case; both knee and lower limb deformities were corrected, with only mild recurrence of knee flexion deformity in 1 case. The foot/ankle and knee joint function improved. Based on QIN Sihe's Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction, outcomes were rated as excellent in 30 cases and good in 2 cases, with an excellent-good rate of 100%. CONCLUSION Foot and ankle deformities combined with knee and lower limb deformities are complex, QIN Sihe's surgical strategy can achieve satisfactory clinical outcomes for simultaneous correction.

Objective To summarize the clinical characteristics of patients with acute posterior circulation large artery occlusive stroke within 6 hours via endovascular therapy and analyze the risk factors for poor prognosis. Methods Clinical data of 43 patients with acute posterior circulation large artery occlusive stroke within 6 hours from January 2017 to June 2023 in the Department of Neurosurgery of the Affiliated People's Hospital of Jiangsu University were collected. The baseline data, the vascular recanalization rate, symptomatic intracranial hemorrhage rate, 90 d good prognosis [modified Rankin Scale (mRS) score≤2] rate, and mortality were analyzed retrospectively. Univariate and multivariate Logistic regression analyses were applied to analyze the risk factors associated with poor prognosis (mRS score>2). Results After endovascular treatment, successful revascularization was achieved in 34 cases, and 4 cases developed symptomatic intracranial hemorrhage. At the 90-day follow-up, 20 patients had good outcomes, 12 had poor outcomes, and 11 died. Univariate analysis suggested that there was a statistically significant difference in preoperative NIHSS scores between the two groups (P < 0.05). Binary logistic regression analysis showed that a high preoperative NIHSS score was an independent risk factor for poor prognosis. Conclusion Early endovascular treatment can significantly improve the revascularization rate and prognosis of patients with acute posterior circulation large artery occlusion stroke. Preoperative NIHSS score can be used as an independent influencing factor to predict the prognosis of patients.
