Objective To observe the effect of biofeedback therapy combined with electrical stimulation in patients with traumatic faecal incontinence.Methods Eishty-two patients with traumatic faecal incontinence were treated once daily with electric stimulation delivered via an intra-anal electrode.They also followed a biofeedback regimen including strengthening,sensory and coordination biofeedback.The whole progrtun consisted of 3 sessions of supervised treatment in hospital followed by 3 sessions of home therapy(10 days per session with an interval of 7days between the sessions).Clinical scores and anorectal function were assessed before and after the program.Results Before treatment,there were 9 patients with good clinical scores,and the general rate of fair and poor clinical scores Was 89%.After therapy,61 patients had good scores,and the general rate of fair and poor Was 26%.Anorectal squeeze pressure and sphincter electromyographic amplitude had improved significantly,the rectal sensory threshold Was decreased significantly,and 76%of the patients who had no external anal sphincter reflex recovered.At the two years follow-up,68% of the patients had maintained the clinical outcomes.Conclusion Biofeedback therapy in conjunction with electrical stimulation has significant therapeutic effects on patients with traumatic faecal incontinence.

Objective:To investigate the clinical characteristics and therapeutic laparoscopy treatment for superior mesenteric artery syndrome(SMAS) in children.Methods:A retrospective study on 5 children with SMAS who failed to respond to the conservative treatment in the Second Hospital of Shandong University from March 2017 to March 2022 was carried out.All the patients underwent the laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure.The clinical data were analyzed and literature retrieved from Wanfang and PubMed databases were reviewed.Results:There were 3 boys and 2 girls in the 5 cases with SMAS.The average age was (12.4±1.4) years, and the preoperative body mass index was (15.2±0.8) kg/m 2.The patients were admitted to the hospital with vomiting, abdominal pain and emaciation symptoms, and the duration of symptoms was (8.4±7.8) months.Gastroscopy, laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure were performed successfully in all the patients, without conversions to open surgery.The average operation duration was (66.0±10.7) min.Food intake was allowed 1 day after surgery.Chylous fistula occurred 4 days after operation in one patient, whose symptom relieved after 11 days of conservative treatment.One patient still had nausea and vomiting symptoms 10 days after operation and was healed by knee-chest posture treatment.No other short-term complications were observed.The median postoperative duration of stay in the hospital was 7 (6-22) days.The patients were followed up for 9-56 (median: 21) months.All of them recovered well and gained weight.One patient had mild recurrent symptoms, and was cured after conservative treatment.A total of 15 literature on the treatment of SMAS by laparoscopic lysis of the ligament of Treitz was retrieved, and the cure rate was 40%-100%.Only one group of these cases had a cure rate below 75%. Conclusions:The laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure is safe, effective, simple and minimally invasive treatment for children with SMAS.It can be used as the first choice for most pediatric patients.

Objective:To investigate the clinical features of neonatal testicular torsion and to evaluate the effect and necessity of early intervention.Methods:A retrospective analysis was performed on 11 neonates admitted to the Second Hospital of Shandong University with neonatal testicular torsion from June 2017 to June 2022. Clinical data of these cases including clinical manifestations, ultrasonography findings, surgical management and outcomes were reviewed and analyzed with descriptive statistical methods.Results:The median age of the 11 patients on admission was 2.6 d (1-5 d). The median time from finding abnormal scrotum to admission was 12 h (1-120 h). Various degrees of scrotal swelling or scleroma were found in the patients. Among them, seven patients presented with acute inflammatory signs of cyano sis or skin redness, and testis-like tissue induration could be touched. Ultrasound scan showed abnormal blood flow in the affected testicle in all cases. Emergency scrotal exploration under general anesthesia was performed successfully in all cases and ten of them underwent orchiectomy of the affected testicle plus contralateral orchiopexy. The rest one who was admitted within 1 h after birth only underwent orchiopexy of the affected testicle as the parents refused contralateral testicular exploration. During the operation, 12 twisted testis were observed, including seven with extravaginal torsion, three with intravaginal torsion and two adhering to the surrounding tissue without normal testicular tissue or distinguishable torsion direction or degree. In this study, ten patients had unilateral testicular torsion, which affected the left side in seven cases and the right side in three cases, and one had bilateral testicular torsion, which was diagnosed as left testicle torsion before surgery. During scrotal exploration, the left testicle of this bilateral case was resected due to necrosis, while the right testicle twisted about 180 degrees with good blood flow and was subjected to orchidopexy after reduction. In one case, the unaffected testicle was unfixed and dysplastic during contralateral exploration, which was also subjected to orchidopexy. In the 12 testis with torsion, one testicle of the patient admitted within 1 h after birth and the right testicle of the bilateral case were preserved with a salvage rate of 2/12. Pathological examination showed necrosis in the ten excised testis, and fibrosis and calcification foci in two of them. None of the patients had any perioperative complications and the scrotal incision healed well in all neonates. The patients were followed up for 6-12 months with regular ultrasound. The two preserved testis and the contralateral testis subjected to orchidopexy were located in the scrotum with good blood supply, and no torsion, atrophy or other abnormalities occurred.Conclusions:Neonatal testicular torsion is rarely seen in clinical practice and has no specific manifestations. It has a high excision rate due to testicular necrosis. Early diagnosis and bilateral scrotal exploration are crucial to the prognosis and the keys to save the affected testis and avoid anorchidism.

Objective: To identify the specific Hub genes in young hepatocellular carcinoma (HCC) patients, and to explore their biological and clinical significance by using bioinformatic methods. Methods: The data information of HCC and normal tissues of young (≤40 years old at diagnosis) and old (＞40 years old at diagnosis) HCC patients were obtained from GEO chip data set GSE45267. The differentially expressed genes (DEGs) in HCC tissues as comparing to normal tissues in the two groups were screened by using GEO2R and Venn chart software. The Protein-Protein Interaction (PPI) network of the specific DEGs in young group was constructed by bioinformatics tools STRING and Cytoscape to screen the Hub genes and significant modules. The Hub genes were verified by GEPIA database, and the overall survival time was analyzed by Kaplan-Meier. Finally, Gene Ontology (GO) Enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were used to analyze the DEGs specific to young group and the common DEGs of the two groups by DAVID. Results: Finally, 117 up-regulated and 179 down-regulated DEGs specific to the young group were screened out, and PPI network screened 10 most connected genes as Hub genes, among which 7 Hub genes were concentrated in the first module. Six up-regulated Hub genes, including TYMS, CDC6, BUB1, TPX2, OIP5 and KIF23, were indicated to associate with the poor prognosis in young HCC patients by GEPIA and Kaplan-Meier analysis. GO function and KEGG pathway analyses showed that the DEGs specific to young HCC patients were mainly involved in biological processes such as ATP binding, and were mainly enriched in S phase of cell cycle; while the common DEGs of two groups were mainly involved in biological processes such as cyclooxygenase P450 and cell division, and were mainly enriched in the G2/M phase of the cell cycle. Conclusion: In this study, 6 up-regulated DEGs specific to young group that suggested poor prognosis were identified, which may be the potential therapeutic and prognostic targets for young patients with HCC.
