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.

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.

Background::Somatic copy number variations (SCNVs) in the CDKN2A gene are among the most frequent events in the dysplasia-carcinoma sequence of esophageal squamous cell carcinoma. However, whether CDKN2A SCNVs are useful biomarkers for the risk stratification and management of patients with esophageal squamous cell dysplasia (ESCdys) is unknown. This study aimed to investigate the characteristics and prognostic value of CDKN2A SCNVs in patients with mild or moderate (m/M) ESCdys. Methods::This study conducted a prospective multicenter study of 205 patients with a baseline diagnosis of m/M ESCdys in five high-risk regions of China (Ci County, Hebei Province; Yanting, Sichuan Province; Linzhou, Henan Province; Yangzhong, Jiangsu Province; and Feicheng, Shandong Province) from 2005 to 2019. Genomic DNA was extracted from paraffin biopsy samples and paired peripheral white blood cells from patients, and a quantitative polymerase chain reaction assay, P16-Light, was used to detect CDKN2A copy number. The cumulative regression and progression rates of ESCdys were evaluated using competing risk models. Results::A total of 205 patients with baseline m/M ESCdys were enrolled. The proportion of ESCdys regression was significantly lower in the CDKN2A deletion cohort than in the diploid and amplification cohorts (18.8% [13/69] vs. 35.0% [28/80] vs. 51.8% [29/56], P <0.001). In the univariable competing risk analysis, the cumulative regression rate was statistically significantly lower ( P = 0.008), while the cumulative progression rate was higher ( P = 0.017) in ESCdys patients with CDKN2A deletion than in those without CDKN2A deletion. CDKN2A deletion was also an independent predictor of prognosis in ESCdys ( P = 0.004) in the multivariable analysis. Conclusion::The results indicated that CDKN2A SCNVs are associated with the prognosis of ESCdys and may serve as potential biomarkers for risk stratification.
