Objective To investigate the safety,feasibility,and surgical skills of laparoscopic high ligation of the hernia sac after laparoscopic appendectomy in children with gangrenous perforated appendicitis or peri-appendiceal abscess.Methods Between February 2015 and May 2024,laparoscopic high ligation of the hernia sac was conducted in 9 cases of gangrenous perforated appendicitis and 3 cases of peri-appendiceal abscess who had undergone laparoscopic appendectomy for 4 months to 3 years and 8 months(mean,1 year and 4 months).Clinical data of these patients was retrospectively reviewed and summarized.Results All the 12 patients were found to have adhesion of greater omentum to the patent tunica vaginalis with folded peritoneum around inner ring orifice.For 3 cases of adhesion to the inner ring orifice,the greater omentum adhesion was released followed by two-port laparoscopic inner ring closure assisted by extracorporeal suture traction,the operative time being 18 min,21 min,and 22 min,respectively.For 8 cases of adhesion to the wall of the tunica vaginalis and 1 case of adhesion to bottom of the tunica vaginalis,the greater omentum adhesion was released and disconnected by using an electric hook followed by three-port laparoscopic inner ring closure assisted by forceps pulling the thick peritoneum,the operative time being(45.5±5.7)min.No intraoperative complications were found and the patients were discharged within 6 h postoperatively.A total of 11 patients were followed up for 4-20 months(mean,7.5 months).One patient was found contralateral inguinal hernia at 1 year and 7 months postoperatively,and high ligation of the hernia sac was conducted after re-admission.No incision infection,hydrocele,iatrogenic cryptorchidism,or testicular atrophy.Conclusions After laparoscopic appendectomy,there is a possibility of the greater omentum adhesion to the inguinal canal during laparoscopic high ligation of the hernia sac.During the operation,it is advisable to add a trocar for assisting the detachment of the greater omentum and fully exposure of the inner ring orifice and retroperitoneum.While protecting the spermatic cord blood vessels,vas deferens,and testes,the greater omentum can be loosened and detached,and high ligation of the hernia sac can be performed.This operation is safe and feasible.

Objective To summarize the best evidence of early rehabilitation management of hand function in patients with hand burn,and provide basis for medical personnel to carry out early rehabilitation management of hand burn.Methods According to the 5S model,all evidence on early rehabilitation management of hand function in patients with hand burns was retrieved from databases and websites including UpToDate,BMJ Best Practice,NICE,RNAO,GIN,and so on.The retrieved evidence included clinical decisions,guidelines,evidence summaries,expert consensuses,systematic reviews,Meta analysis.The search period of the summary of best evidence,expert concensus and guidelines are from the establishment of the database to December 20,2024,and the search period of the systematic reviews is from January 1,2019 to December 20,2024.Quality evaluation of literature,evidence extraction and summary were conducted.The evidence was graded according to JBI evidence pre-grading system 2014.Results Totally 17 pieces of the literature were included,including 1 clinical decision,4 guidelines,6 evidence summaries,3 expert consensus articles,and 3 systematic reviews.Totally pieces of best evidence were summarized,including 7 aspects of assessment,hand positioning,treatment of edema,dressing,use of orthotics,joint mobility training,and health education.Conclusion This study summarized the best evidence of early rehabilitation management of hand function in patients with hand burn,and provided evidence-based evidence for clinical rehabilitation management plan.According to the clinical situation,the medical staff can apply the evidence to clinical practice,so as to improve the hand function and quality of life of patients.

Objective To systematically review the advantages and disadvantages of capping and non-capping decannulation strate-gies in adult tracheostomized patients.Methods The PICO framework was developed.Literatures on decannulation measures in adult tracheostomized patients were searched in PubMed,EMbase,Cochrane Library,CNKI,Wanfang Database and SinoMed from establish-ment to February 1st,2025.The non-capping group included patients who underwent decannulation after passing the assessment,without≥24 hours of tube capping.The capping group included patients who underwent≥24 hours of tube occlusion before decannulation.Study types included randomized controlled trial(RCT),cohort studies,and case-control studies.The Newcastle-Ottawa Scale(NOS)was used to evaluate the quality of non-ran-domized studies,while the Cochrane Risk of Bias Tool was applied to assess RCTs.The GRADE was used to evaluate the evidence quality of outcome measures.Relevant information was extracted from the included studies for systematic review.Results A total of six studies were ultimately included,published between 2003 and 2020,originating from Spain,Chi-na,Nepal,and Israel,involving 745 patients.Non-RCT studies scored six to eight points on NOS.Among RCT,one study had a low risk of bias,while another had a moderate risk based on the Cochrane Risk of Bias Tool.Capping strategies included complete capping for 24 to 48 hours before decannulation,stepwise tube downsizing followed by capping,and progressive capping prior to decannulation.Non-capping strategies involved immediate decannulation after passing the assessment or following endoscopic evaluation.Compared with the capping strat-egy,non-capping decannulation significantly reduced decannulation time and incidence of adverse events.No sig-nificant differences were observed in decannulation success rates or pulmonary infection rates between the two strategies.However,findings on pulmonary infections and adverse events were inconsistent across studies.Ac-cording to the GRADE assessment,the strength of evidence was rated as low for decannulation success rate and decannulation time,and very low for incidence of pulmonary infection and adverse events.Conclusion For adult tracheostomized patients,non-capping decannulation strategy appears superior to capping strategy,demonstrating shorter decannulation time and reduced adverse events.No significant difference were observed in decannulation success rates and pulmonary infection rates between the two strategies.

Objective·To study the alterations in vestibular hair cell morphology and function of ATPase plasma membrane Ca2+transporting 2 oblivion(Atp2b2 Oblivion)heterozygous mice at different ages.Methods·Atp2b2 Oblivion heterozygous male mice aged 2 months and 8 months were selected with ten in each kind and C57BL/6J wild-type mice with the same gender,age and number were selected as the control group.Expression patterns of ATP2B2 in vestibular hair cells and numbers of hair cells in the striola zone and the extra striola zone in the two groups of mice at different ages were observed and calculated respectively through immunofluorescence assay.Hair bundle structures were detected by scanning electron microscopy(SEM),and mitochondria and ribbon synapse structures were observed by transmission electron microscopy(TEM).Vestibular evoked potential(VsEP),vestibular evoked myogenic potential(VEMP),rotarod rod test,and balance beam test were adopted for the evaluation of vestibular functions.Results·ATP2B2 was mainly expressed in the hair bundle of vestibular hair cells in the two groups of mice.Hair cell numbers in the striola zone and the extra-striola zone did not exhibit any differences between Atp2b2 Oblivion heterozygous mutant mice and wild-type mice of 2-month-old and 8-month-old.No visible structural abnormality in the hair bundle could be seen through SEM.TEM results implied no morphological abnormality in mitochondria or ribbon synapses in the 2-month-old heterozygous mutant mice,while vacuolar degeneration was discovered in the mitochondria under the cuticular plate in the 8-month-old heterozygous mutant mice with the normal ribbon synapses and the normal mitochondria near the innervation site.VsEP and VEMP thresholds of 2-month-old and 8-month-old Atp2b2 Oblivion heterozygous mutant mice were significantly elevated compared with the wild-type mice.Analysis of VsEP waveform manifested prolonged P1 latency and declined P1N1 amplitude in heterozygous mutant mice(P＜0.05).Results of rotarod rod test and balance beam test acquired from 2-month-old Atp2b2 Oblivion heterozygous mutant mice were not significantly different from the wild-type mice,while the ability of the mutant mice to accomplish the tests descended significantly at 8 months of age compared with the wild-type mice(P＜0.05).Conclusion·Atp2b2 Oblivion heterozygous mutant mice showed defective vestibular electrophysiological function at 2 months old,and abnormalities in vestibule-related behaviors can be detected at 8 months old.The vestibular function ofAtp2b2 Oblivion heterozygous mutant mice deteriorate progressively.

Objective:To evaluate the effect of ultrasound-guided subserratus anterior plane block on postoperative analgesia in patients un-dergoing laparoscopic radical gastrectomy.Methods:Sixty patients who underwent elective laparoscopic radical gastrectomy were enrolled between May 2022 and October 2023 at Tianjin Medical University Cancer Institute&Hospital.Patients were assigned into two groups us-ing a random number table method:the control(group C)and the ultrasound-guided serratus anterior plane block(SAPB)(group S).Patient-controlled intravenous analgesia(PCIA)was administered at the end of the surgery.After surgery,visual analogue scale(VAS)of static pain scores was evaluated at 1,6,12,24,and 48 hours.PCIA pump was started at the VAS pain score≥4 after surgery,and sufentanil 0.1μg/kg was intravenously injected when the efficacy was inadequate.The requirement for PCIA use,time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and the duration of hospitalization stay were recorded for the two groups.Results:VAS scores were significantly lower at postoperative 1,6,and 12 h in group S than in group C(P<0.05).Additionally,the number of effective uses of PCIA,and rescue analgesia were significantly lower in group S[(6.1±0.4)(2)]than in group C[(18.6±1.4)(17)](P<0.001).The time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and duration of hospital stay were shortened in group S than in group C(P<0.05).There were no significant differences in other parameters between these two groups.Conclusion:Ultrasound-guided SAPB can reduce postoperative pain and facilitate fast recovery in laparoscopic radical gastrectomy patients.

Objective:To evaluate the effect of ultrasound-guided internal branch of superior laryngeal nerve(ibSLN) block on the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.Methods:The data from patients of either gender, aged 18-65 yr, with a body mass index of 18-28 kg/m 2, who underwent intracranial tumor surgery from December 2022 to October 2023, were retrospectively collected. Patients were divided into control group (group C) and ultrasound-guided ibSLN block group (group U). Bilateral ibSLN block was performed with 0.375% ropivacaine hydrochloride 2 ml.The tracheal extubation time, emergence time, development of cardiovascular events within 15 min after extubation, emergence agitation, Ramsay sedation score, Steward recovery score, visual analogue scale scores at 10 min after extubation and development of postoperative sore throat and hoarseness in postanesthesia care unit were recorded. Results:Compared with group C, the incidence of emergence agitation, Ramsay sedation score, visual analogue scale scores and sore throat were significantly decreased, the incidence of hoarseness was increased ( P<0.05), and no significant change was found in the extubation time, emergence time and Steward recovery score in group U( P>0.05). No hypertension, hypotension, tachachycardia and bradycardia were found in two groups. Conclusions:Ultrasound-guided ibSLN block can improve the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.

OBJECTIVE To explore the potential mechanism of Yishenqinglihuoxue Formula(YSQLF)in treating chronic kidney disease fibrosis in rats based on UHPLC-Q-TOF-MS technology and network pharmacology.METHODS UHPLC-Q-TOF-MS was used for qualitative analysis of Yishenqinglihuoxue Formula-containing serum.Targets of the plasma constituents and the disease were retrieved from SwissTargetPrediction,OMIM,GeneCards,and other databases.Then the protein-protein interaction(PPI)network was constructed and core targets were screened for GO term enrichment and KEGG pathway enrichment.Cytoscape software was em-ployed to construct the"drug-compound-core target-pathway"network and the targets and signaling pathways of Yishenqinglihuoxue Formula against fibrosis were predicted.A model of renal fibrosis was established to verify the core targets and pathway proteins.RE-SULTS A total of 56 constituents migrating to blood of Yishenqinglihuoxue Formula were identified.97 common targets of the constit-uents and the disease and 33 core targets were screened out.KEGG enrichment and PPI network analysis showed that Yishenqingli-huoxue Formula may play a role in the treatment of fibrosis through PI3K/Akt and other pathways.Furthermore,the results of animal experiments showed that Yishenqinglihuoxue Formula could reduce the levels of Scr and BUN,improve fibrosis areas,inhibit the acti-vation of the PI3K/Akt pathway,and reduce the protein expression of TNF-α.CONCLUSION Yishenqinglihuoxue Formula may play a role in the treatment of fibrosis by inhibiting PI3K/Akt signaling pathway and inhibiting TNF-α expression.
