AIM: To investigate the effect and potential mechanism of liraglutide(LIR)combined with neural stem cells(NSCs)in alleviating diabetic retinopathy(DR)in rats.METHODS:A DR rat model was established using a high-fat diet combined with a single intraperitoneal injection of streptozotocin(STZ). Rats in the control group were fed a normal diet and received an intraperitoneal injection of citric acid-sodium citrate buffer. After modeling, the rats were divided into the control group, DR group, DR+LIR group, DR+BMSCs group, DR+NSCs group, DR+BMSCs+LIR group, and DR+NSCs+LIR group. According to the grouping instructions, rats were given intraperitoneal injection of LIR at 200 μg/(kg·d)and intravitreal injection of bone marrow mesenchymal stem cells(BMSCs), or NSCs, or the combined therapy accordingly for 8 wk. Fasting blood glucose(FBG)and serum insulin levels, as well as retinal oxidative stress indexes and serum inflammatory indexes, were detected in each group. Retinopathy was evaluated by hematoxylin-eosin(HE)staining, retinal cell apoptosis was detected by TUNEL staining, SIRT1 expression in retinal tissues was detected by immunohistochemistry, and BDNF expression in retinal tissues was detected by immunofluorescence. The transcriptional levels of cZNF532, miR-29a-3p, SIRT1, TGF-β1, NRF2, Keap1, and BDNF in retinal tissues were detected by qRT-PCR, and the protein expression levels of SIRT1, TGF-β1, SMAD2/3, p-SMAD2/3, NRF2, Keap1, p65, and p-p65 in retinal tissues were detected by Western blot. RESULTS:Compared with the other groups of rats, the retinal morphology of rats in the DR+NSCs+LIR group was significantly improved, the levels of FBG, TNF-α, IL-1β, IL-6 and MDA were decreased(all P<0.05), the serum insulin level and the levels of SOD, CAT, and GSH-Px were increased(all P<0.05), the TUNEL-positive rate of retinal cells was reduced(all P<0.05). The expression levels of cZNF532, SIRT1, NRF2, and BDNF in retinal tissue were up-regulated(all P<0.05), whereas the expression levels of miR-29a-3p, TGF-β1, p-SMAD2/3, Keap1, and p-p65 were down-regulated(all P<0.05). CONCLUSION:LIR combined with NSCs alleviates DR by regulating the cZNF532-miR-29a-3p-SIRT1 network and its downstream TGF-β/SMAD, NF-κB, and Keap1/NRF2 signaling pathways.

Objective:
To explore the facilitating and hindering factors of mental health promotion activities in junior and senior high schools from teachers perspectives, as well as coping strategies, so as to provide evidence for implementing teacher led mental health promotion programs.
Methods:
From September 2023 to September 2024, by using purposive sampling method, 5 junior high schools, 5 regular high schools, 2 vocational high schools in four provinces and municipalities (Tianjin, Shanxi, Shandong, and Jiangxi) were selected. A total of 92 teachers (78 homeroom teachers and 14 full time or part time psychological counselors) were interviewed using semi structured focus group discussions (one session per school, totaling 12 sessions). Thematic analysis was applied to code and analyze the interview transcripts.
Results:
The implementation of mental health promotion activities in middle schools was influenced by three levels: teachers, schools and society. Specifically, teachers exhibited a high support low capability phenomenon (81 participants supported conducting such activities, but 71 felt lacking in professional capacity); activity effectiveness and support systems were imbalanced (42 mentioned significant effects, while 78 reported insufficient support); there was a mismatch between student demand and activity content (9 mentioned students had psychological needs, but 11 indicated existing activities failed to meet these needs); administrative support and sustainability showed disparities (14 believed sufficient administrative support existed, while 37 noted sustainability issues); parental awareness and participation remained inadequate (11 highlighted parents need for mental health knowledge, and 37 perceived insufficient understanding of psychological issues among parents). Effective strategies included enhancing teachers effectiveness, providing essential skill training, focusing on the needs of teenagers,enhancing program sustainability, and eliminating misconceptions about mental health among parents.
Conclusion
Mental health promotion activities in junior and senior high schools should focus on enhancing teachers skills, improving activity sustainability, reducing stigma among parents, and establishing a collaborative network for school based mental health promotion.

Narrative is the cornerstone of interpersonal relationships and life safety. However, its important value in daily life, school education, health management, personal happiness, career development, and other aspects has been ignored. The narrative ecology of families, schools, hospitals, workplaces, and elderly care institutions is worrying, the narrative connection between parent-child and intergenerational is broken, the narrative nature of adolescents is ignored, the narrative demands of patients are neglected, narrative relationships in the workplace are indifferent, and the narrative capital of the elderly is idle. These issues have resulted in serious social problems, such as depression and suicide among adolescents, conflicts between doctors and patients, workplace and life burnout among middle-aged people, and the inability of the elderly to achieve healthy aging, which have become a “stumbling block” to the realization of holistic health. Advocating the construction of narrative ecology and interpersonal narrative connections is an important measure of achieving holistic health. Taking the “narrative concept” as the overall framework, and based on the research, education, and practice carried out by the Alliance of Narrative Medicine in Higher Education Institutions, this paper proposed that actively build China’s narrative system of life and health, to enable narrative play an active and dynamic role in the construction of narrative ecology in different spaces, such as the families, the schools, the hospitals, the workplaces, and the elderly care institutions, as well as practically improve the quality of life of the people.

OBJECTIVE:
To analyze the clinical characteristics of a patient with Short rib-polydactyly syndrome type 6 (SRTD6) with long-term misdiagnosis, and improve its clinical recognition by reviewing the relevant literature.
METHODS:
A patient presented at the Children's Hospital Affiliated to Zhejiang University School of Medicine on August 19, 2024 for the discovery of liver dysfunction for 13 years and vision loss for 9 years was selected as the study subject. Her medical history, clinical data, laboratory findings and results of imaging examination were collected. High-throughput sequencing was carried out, and candidate variants were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Hospital (Ethics No.: 2021-IRB-292).
RESULTS:
The patient had long-term unexplained liver dysfunction, vision loss, and growth delay. Blood acylcarnitine and urinary organic acid analysis have failed to found any abnormality. Previous genetic testing revealed a homozygous c.203A>C (p.Glu68Ala) missense variant in the ETFDH gene, leading to a misdiagnosis of various acyl-CoA dehydrogenase deficiencies. However, treatment with high-dose vitamin B2 showed a poor effect. Physical examination revealed small hands, short and stubby fingers, and a narrow chest. Medical imaging showed shortened bilateral ribs, a narrowed chest, and short, thick metacarpals. High-throughput sequencing has detected a pathogenic homozygous c.1957C>T (p.R653*) nonsense variant in the NEK1 gene, confirming the diagnosis of SRTD6.
CONCLUSION
SRTD6 is characterized by rib and sternum dysplasia as the primary skeletal deformities, which is often accompanied by multi-organ impairment. Genetic testing can facilitate the precise diagnosis.

Intraoperative neural monitoring (IONM) is a critical technique for the protection of recurrent laryngeal nerve (RLN) function during thyroid surgery. In recent years, continuous innovations in IONM have established it as a cornerstone of modern thyroid surgery. However, current methodologies still exhibit limitations in the accurate assessment of neural function, and guidelines have yet to provide clear strategies for managing patients with intraoperative signal loss who subsequently develop postoperative voice disorders. This article reviews representative advances in the application of deep learning to bioelectrophysiological signals and systematically summarizes the use of deep learning in the field of voice medicine, thereby exploring the feasibility of integrating IONM with deep learning technologies.

Hepatitis B virus (HBV) infection is a major global public health problem. There will be about 257 million chronic HBV-infected patients worldwide, according to the World Health Organization's estimation by 2025. Currently, the main drugs for the treatment of chronic HBV infection are nucleos(t)ide analogues and pegylated interferon (PEG-IFN). However, previous research results show that whether it is nucleos(t)ide analogues and PEG-IFN-α monotherapy or combination therapy, or sequential combination therapy, the rate of hepatitis B surface antigen seroconversion in patients is low, and there is still a high risk of disease progression after a certain course of antiviral treatment. Therefore, to achieve the ambitious target of "eliminating viral hepatitis by 2030" set by the World Health Organization and help more hepatitis B patients achieve functional cure, a large number of new drugs have been developed and entered clinical trials. This paper summarizes and reviews the types, safety, and efficacy of new drugs to further promote advancements in the field of treatment of chronic HBV infection.
