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.

Objective:To understand the molecular evolutionary characteristics of the recombinant strain GII.3[P12] of norovirus acute gastroenteritis outbreaks and aggregated outbreaks in China from 2022 to 2023.Methods:Epidemiological information, case information, clinical samples, as well as detection and genotyping information of norovirus outbreaks and aggregated outbreaks from 2022 to 2023 were collected; positive samples of the GII.3[P12] recombinant strain were subjected to nucleic acid extraction, whole-genome amplification, and sequence analysis; and homology simulation method were used to construct a three-dimensional structure and predict antigenic epitopes.Results:From January 2022 to December 2023, a total of 1 136 norovirus outbreaks and aggregated outbreaks were reported in China′s norovirus outbreak surveillance network, and genotyping result were successfully obtained for 942 outbreaks, with GII dominating, accounting for 76.0% (716/942), and the proportion of GI and mixed genotypes being 15.8% (149/942) and 8.2% (77/942). Norovirus outbreaks caused by GII were dominated by GII.3[P12] (22.5%, 161/716), while other major genotypes included GII.17[P17] (18.7%, 134/716), GII.4_Sydney 2012[P16] (11.6%, 83/716) and GII.6[P7] ( 11.3%, 81/716). 2022-2023 Outbreaks caused by GII.3[P12] were concentrated in February-March (54.0%, 87/161), with the main outbreaks occurring in nursery and primary schools (87.5%), the mode of transmission was mainly human-to-human (68.9%), and the main susceptible population was children aged 3-7 years (93.3%). In this study, the genome sequences of 25 GII.3[P12] recombinant strains were obtained, and according to the phylogenetic analysis, it was shown that the GII.3[P12] recombinant strains in China in 2022-2023 belonged to the Cluster IV cluster of sublineage b (7 strains) and sublineage c (18 strains). A total of 11 linear and 8 conformational epitopes were predicted by epitope prediction analysis, and the predicted linear and conformational epitopes had overlapping positions, and each conformational epitope was part of the predicted linear epitope with conserved potential antigen-binding and receptor-binding sites.Conclusions:The recombinant strain GII.3[P12] is one of the epidemic strains that will cause outbreaks and clusters of norovirus in China in 2022-2023, and its genome did not undergo significant mutation.

Although percutaneous pulmonary artery denervation (PADN) has demonstrated long-term benefits in combined post- and pre-capillary pulmonary hypertension, its usefulness for isolated post-capillary pulmonary hypertension (IpcPH) remains unclear. This report presents 2 cases of IpcPH due to left heart failure who underwent PADN treatment following an insufficient response to optimized conventional therapy. This case study illustrates how PADN, when combined with heart failure guideline-directed medical therapy, may represent a promising treatment option for IpcPH.

Objective To investigate the clinical efficacy of the"dynamic and static combination"approach in the treatment of Hepple Ⅰ-Ⅲ type osteochondral lesions of the talus(OLT),utilizing external ankle shaking,pulling,and poking manipulations in conjunction with ankle brace fixation.Methods A total of 82 patients diagnosed with OLT,who sought treatment at four hospitals between June 2022 and December 2023,were included in the study.Both the experimental and control groups received ankle immobilization using braces through-out the treatment period.The control group was administered Voltaren Emulgel topically twice daily(morning and evening),with each treatment course lasting 30 days,for a total of one course.The experimental group received additional therapeutic intervention involving shaking,pulling,and poking manipulations,conducted twice weekly,with the same duration and number of treatment courses as the control group.Follow-up assessments were scheduled at 2 weeks,4 weeks,and 2 months post-treatment.Outcome measures included the pain rating index(PRI),visual analogue scale(VAS)for pain intensity,current pain intensity(PPI),American Orthopaedic Foot & Ankle Society(AOFAS)ankle and hindfoot scores,proprioceptive function,and the size of OLT.Results During the longitudinal assessment conducted at 2-week,4-week,and follow-up intervals,the experimental group exhibited superior clinical outcomes compared to the control group,with statistically significant decreases in PRI,PPI,and AOFAS scores(all P＜0.05).VAS scores showed progressive improvement over time,with significant intergroup differences observed at both the 4-week and follow-up assessments(P＜0.05).Biomechanical analysis performed post-intervention indicated improved kinematic repositioning accuracy in the experimental group,as reflected by significantly reduced active-passive error angles(P＜0.05).Importantly,measurements of OLT area revealed notable therapeutic effects in the experimental group(P＜0.05),whereas no statistically significant changes were observed in the control group throughout the study period(all P＞0.05).Conclusions Under the guidance of the"dynamic and static combination"concept,the integration of shaking,pulling,and poking manipu-lation with conventional Western medicine-based conservative treatment for OLT demonstrates more pronounced advantages in alleviating pain,improving ankle joint function,restoring proprioception,facilitating lesion recovery,and enhancing overall quality of life.

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 causal relationship between use of analgesic drugs and incidence of Clostridium difficile enteritis(CDE).Methods Univariate and multivariate Mendelian randomization(MR)methods were employed to investigate the potential causal relationship between use of analgesic drugs and incidence of CDE,using inverse variance weighted as the primary analytical approach.Results Univariate MR analysis indicated that use of nonsteroidal anti-inflammatory drug(NSAID)(OR=2.680,95％CI:1.689-4.252,P＜0.001)and aniline derivatives(OR=2.521,95％CI:1.503-4.229,P＜0.001)increased the risk of CDE,whereas use of opioids(OR=0.955,95％CI:0.818-1.114,P=0.556)and salicylates(OR=1.081,95％CI:0.820-1.425,P=0.579)were not identified as risk factors for CDE.The MR-Steiger test did not suggest the presence of reverse causality between exposure and outcome.After adjustment in the multivariate MR analysis,the use of NSAID was no longer a risk factor for CDE(OR=1.709,95％CI:0.864-3.308,P=0.123),while use of aniline derivatives remained a risk factor(OR=2.147,95％CI:1.239-3.721,P=0.003).Sensitivity analyses showed no evidence of heterogeneity,horizontal pleiotropy,or outliers,and no single nucleotide polymorphisms independently influenced the results.Conclusion The use of opioids does not increase the risk of CDE infection.The causal relationship between NSAID use and CDE remains inconclusive.However,the use of aniline derivatives within the NSAID class is a risk factor for CDE,while use of salicylates is not a risk factor for CDE.

Perimenopausal women are more susceptible to fire pathogen disturbances,often resulting in the restlessness of the mind owing to the deficiency and decline of the thoroughfare and conception vessels,as well as the insufficiency of the essence and blood of the viscera.CHENG Zhongling's theory of thief and child fire in Medical Insights proposes that thief fire primarily arises from exogenous pathogen invasion and improper diet,leading to syndromes such as food retention in the stomach or phlegm-fire stagnation.In contrast,child fire is generated endogenously,often owing to liver and kidney deficiency,resulting in an imbalance of water and fire and liver dysfunction,leading to excessive fire transformation.This theory provides a novel perspective for understanding the pathogenesis of perimenopausal insomnia.An in-depth exploration of the role of thief fire and child fire in perimenopausal insomnia is presented,along with a detailed discussion of corresponding treatment strategies.For the invasion of thief fire,therapeutic approaches include ascending and dispersing stagnant fire,clearing and moistening to remove interior heat,purging the heat accumulation to unblock the bowels,and subduing the fire and nourishing yin to eliminate depression.When child fire disturbs the spirit,treatment methods involve smoothing and relieving the liver qi to clear the stagnant heat,nourishing the true yin to restrain the yang,warming and nurturing the primordial qi and harmonizing the nutrient and defensive qi,and guiding and reducing the deficient heat to remove the floating fire.Clinical practice necessitates precise identification of thief and child fire,thorough investigation of exogenous pathogens and internal damage,and careful differentiation between deficiency and excess,as well as the superficial and internal aspects.Strict adherence to the treatment principle of"nourishing the child fire can drive out the thief fire,but driving out the thief fire should not harm the child fire"ensures a balanced approach.By harmonizing the yin and yang of the viscera and allowing the mind to be at ease,this strategy effectively alleviates perimenopausal insomnia.The application of these principles provides a practical and feasible theoretical foundation and practical guidance for the treatment of perimenopausal insomnia using traditional Chinese medicine.

Perimenopausal anxiety and depression state fall under the categories of"visceral agitation"and"perimenopausal syndrome"in traditional Chinese medicine(TCM).Grounded in the theory of"Yang transforms qi,yin shapes form",this study posits that the pathogenesis of this condition is complex,often presenting with concurrent deficiency and excess syndromes,and is closely associated with yang deficiency-induced stagnation and qi stagnation leading to mental decline.The pathological mechanism is summarized as yang deficiency being the root and qi stagnation the manifestation.This article proposes a"yang-oriented treatment"approach for perimenopausal anxiety-depression disorders,employing a stepwise integrated acupuncture protocol termed"One Needling,Two Moxibustion,Three Consolidation":"One Needling"prioritizes regulating qi flow via acupuncture to soothe the liver and harmonize the spirit;"Two Moxibustion"utilizes refined moxibustion to warm yang,resolve stagnation,and activate yang circulation;"Three Consolidation"combines bloodletting therapy to remove stasis and regenerate tissues with intradermal needle embedding to stimulate yang and regulate visceral functions.This synergistic protocol aims to nourish the heart-mind,awaken the orifices of consciousness,alleviate perimenopausal anxiety and depressive symptoms,and consolidate therapeutic efficacy.
