In recent years， the incidence of depression among adolescents has increased significantly， becoming a serious global public health problem. There is a close relationship between adolescent depression and lipid metabolism abnormalities. However， the mechanisms underlying this association have not been fully elucidated. This article provides a review of the mechanisms and interventions linking adolescent depression and lipid metabolism abnormalities， aiming to offer new ideas for interventions in adolescent depression. Using computerized searches of the China National Knowledge Infrastructure （CNKI）， Wanfang Data， PubMed， and Web of Science， studies on the mechanisms and interventions related to adolescent depression and lipid metabolism were collected， with the search period extending up to October 10， 2025. Two researchers independently conducted literature screening and extracted basic information from the included studies. A total of 12 original studies were included. The results indicate that adolescent depression is associated with certain lipid metabolites. Neurobiological factors， immune inflammation， oxidative stress， and gut microbiota imbalance play important roles in this association. In addition， lipid metabolites such as omega-3 polyunsaturated fatty acids （ω-3 PUFAs） have a significant ameliorating effect on adolescent depression. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）； Shenzhen Science and Technology Program （number， 20210617155253001）］

Background/Aims: This study aimed to assess the impact of INTERCEPT Foam Spray (IFS) application on delayed endoscope reprocessing through microbiological surveillance culture (MSC). Methods: A quasi-experimental, matched-comparison pilot study was conducted using gastrointestinal endoscopy. IFS was applied to the endoscopes after precleaning and before reprocessing the next day. An equal number of endoscopes, matched by endoscope type, were subjected to routine reprocessing. The MSC were subjected to high-level disinfection to detect any contamination. Data were analyzed using the chi-square test or Fisher exact test (categorical data) and Student t-test (continuous data). Results: In total, 150 MSCs were collected from 42 endoscopes. Positive MSCs were observed in 4.0% (4/75) of the sprayed group and 1.3% (1/75) of the control group (95% confidence interval, 30.34–0.31; p>0.05), all of which were contributed by colonoscopes. Colonoscope were more prone to positive MSC (mean difference in percentage, p<0.05). Mean spraying hours were not associated with detected growth (11.7% vs. 13.6%; 95% confidence interval, 1.43 to –5.27; p>0.05), with environmental and skin flora being the primary contaminants. Conclusions IFS may be applied when delayed endoscope processing is necessary, but with caution when applied to colonoscopes. However, further research is warranted to verify the result.

Objective:To analyze the feasibility and safety of microsurgical anastomosis for obstructive azoospermia (OA) patients with prior intracytoplasmic sperm injection (ICSI) failure.Methods:From September 2015 to May 2020, the data of 20 OA patients with previous ICSI-assisted pregnancy failure admitted to the Department of Andrology, Urologic Medical Center, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. The characteristics of seminal tract microsurgical reconstruction were summarized, and the postoperative recurrence rate and clinical pregnancy rate were calculated.Results:Vasal obstruction was found in 8 patients and epididymal obstruction in 12 patients during microscopically reconstructed seminal tract. Among the patients with vasal obstruction, 1 patient developed OA after trauma and underwent laparoscopic-assisted right vasovasostomy (VV). Totally 7 patients developed OA after juvenile bilateral hernia, among whom 6 patients underwent further laparoscopic-assisted VV and 1 patient underwent vasovasostomy and epididymal cross anastomosis. Of the 8 patients who underwent VV, 6 achieved postoperative patency, and 2 couples achieved natural pregnancy. Patients with epididymal obstruction underwent microscopic vasoepididymostomy (VE), and 6 out of 12 patients achieved postoperative pregnancy, while 3 couples achieved natural pregnancy. No significant complications occurred in all patients during and after operation.Conclusion:Microsurgical anastomosis is an effective remedy for patients with OA after ICSI pregnancy failure, which can help patients achieve natural pregnancy.

Objective:To explore the chromosomal genetic factors of maturation arrest non-obstructive azoospermia (NOA).Methods:A case of maturation arrest NOA patients with chromosome reciprocal translocation was retrospective analyzed with literature review.Results:The karyotype of 46,Y,t(X;19)(p22.1;q13.3) was detected in a NOA patient, and the karyotypes of his parents were normal. There were no micro-deletions of Y chromosome. Also, no obvious pathogenic gene mutations were found in whole-exome sequencing (WES). Furthermore, there were no pathogenic copy number variations (CNVs) detected by chromosomal microarray analysis (CMA) in the patient. The histopathological analysis revealed that the spermatogenesis arrested at spermatocyte stage.Conclusion:46,Y,t(X;19) chromosome reciprocal translocation could lead to maturation arrest NOA.

Azoospermia accounts for 10%-15% of male infertility, with the prevalence of 1% in male population. Obstructive azoospermia (OA) accounts for 40% of azoospermia and can be caused by a variety of factors, including male reproductive duct inflammation and genetic factors. Given the fact that the spermatogenesis is normal in the testis of OA patients, the OA patients can have their own offspring through testicular biopsy and sperm retrieval followed by assisted reproductive technology (ART). Therefore, the genetic etiology of OA is often overlooked. Subsequently, studies of the following ART strategies and offspring birth defects are also ignored. This article reviewed the genetic disorders of OA patients, and the animal model with OA, providing new ideas for management of OA patients, genetic counseling, and development of male contraceptives.
