Access to the clinical application of medical technology is one of the core institutional contents of medical quality management， involving medical quality assurance， the achievement of patient safety goals， and medical service satisfaction. Medical technology is only permitted for clinical use after its safety and effectiveness have been verified through clinical research， as well as evaluated and reviewed by the medical technology clinical application management committee and ethics committee of this medical and health institution. Based on the relevant laws， regulations， and ethical principles， combined with the experience of ethical review in the clinical application of medical technology from some medical and health institutions， a thematic discussion was held to formulate ethical review guidelines for the clinical application of medical technology for references. These guidelines elaborated on the management system for access to the clinical application of medical technology in medical and health institutions， the system of ethics committees and the requirements of review norms， technical plans and their review points， key points for the implementation of informed consent， technical teams and conditions， and other aspects.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC). METHODS: A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups. RESULTS: After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

This paper discussed the current education status on medical ethics and styles and the assessment condition in the examination of doctors' qualification， as well as the existing problems and potential solutions by reviewing domestic and foreign literature and summarizing the practice experience. Traditionally， medical ethics and styles have always been integrated into clinical medical practice in China. However， under the modern medical education system， it is challenged to integrate traditional education on medical ethics and styles with the rules of modern medical knowledge. By summarizing the education and assessment status of medical ethics and styles in the examination of doctors' qualification， it is found that the current examination is relatively poor in the evaluation content， and the way of evaluation is not diverse， with lack of curriculum of medical humanities. The solutions suggested are enriching relevant examination content， introducing more and comprehensive evaluation method， and establishing more medical humanities-related courses.

Background Mindful parenting is related to the physical and mental health of adolescents,but only few empirical studies have been conducted on the mindful parenting and none has addressed on the impact and actor-partner effects of mindful parenting on adolescents' aggressive behaviors via parenting stress.Objective To explore the impact and actor-partner effects of mindful parenting on adolescents' aggressive behaviors via parenting stress,so as to provide references for improvements in family education and interventions on behavioral problems in adolescents.Methods A sample of 907 subjects(including family members and students)from three classes in each of five grades from grade 5 in elementary school to grade 9 in junior high school in Mianyang,Sichuan Province were selected from September 8 to 15,2023.Parents were assessed with Mindfulness In Parenting Questionnaire(MIPQ)and Parenting Stress Index-Short Form(PSI-SF),and students were required to fulfill aggressive behavior scale of Youth Self-Report(YSR).Pearson correlation analysis was utilized to examine the correlation among the above scales.The actor-partner interdependence model was used to analyze the impact of mindful parenting on their own and their spouses' parenting stress,as well as the impact on adolescents' aggressive behaviors via parenting stress.Results A total of 472 families completed the effective questionnaires.Both father and mother's mindful parenting exhibited an actor effect on adolescents' aggressive behaviors via their own parenting stress,with the effect size of-0.018(P=0.002)and-0.026(P=0.012).The partner effect sizes of father's mindful parenting and mother's mindful parenting on adolescents' aggressive behaviors via their spouse's parenting stress were-0.006(P=0.026)and-0.007(P=0.012),respectively.Conclusion Mindful parenting has been proven to have specific indirect impact on adolescents' aggressive behaviors through their own and their spouse's parenting stress,and the actor effect and partner effect are found both significant.

Scientific research is an important part of hospital work,the driving force of hospital construction and development,and the key to the hospital's comprehensive competitiveness and future development potential.Scientific research misconduct,which seriously deviates from the recognized norms of the scientific community,and will cause great harm to groups,society,and the public.It may also lead to the spread of false knowledge,resulting in misconceptions among peers and causing losses.By analyzing the scientific research integrity relationship between clinical doctors and clinical researchers,as well as looking at integrity standards from multiple dimensions,this paper found out the similarities and differences in the extension of integrity between them.Exploring measures to further promote the construction of scientific integrity and ethics,especially increasing the supervisory role of discipline inspection and supervision,which is conducive to the promotion of scientific research in the medical field in China.

Auditory neuropathy spectrum disorder (ANSD) represents a variety of sensorineural deafness conditions characterized by abnormal inner hair cells and/or auditory nerve function, but with the preservation of outer hair cell function. ANSD represents up to 15% of individuals with hearing impairments. Through mutation screening, bioinformatic analysis and expression studies, we have previously identified several apoptosis-inducing factor (AIF) mitochondria-associated 1 (AIFM1) variants in ANSD families and in some other sporadic cases. Here, to elucidate the pathogenic mechanisms underlying each AIFM1 variant, we generated AIF-null cells using the clustered regularly interspersed short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system and constructed AIF-wild type (WT) and AIF-mutant (mut) (p.‍T260A, p.‍R422W, and p.‍R451Q) stable transfection cell lines. We then analyzed AIF structure, coenzyme-binding affinity, apoptosis, and other aspects. Results revealed that these variants resulted in impaired dimerization, compromising AIF function. The reduction reaction of AIF variants had proceeded slower than that of AIF-WT. The average levels of AIF dimerization in AIF variant cells were only 34.5%‍‒‍49.7% of that of AIF-WT cells, resulting in caspase-independent apoptosis. The average percentage of apoptotic cells in the variants was 12.3%‍‒‍17.9%, which was significantly higher than that (6.9%‍‒‍7.4%) in controls. However, nicotinamide adenine dinucleotide (NADH) treatment promoted the reduction of apoptosis by rescuing AIF dimerization in AIF variant cells. Our findings show that the impairment of AIF dimerization by AIFM1 variants causes apoptosis contributing to ANSD, and introduce NADH as a potential drug for ANSD treatment. Our results help elucidate the mechanisms of ANSD and may lead to the provision of novel therapies.

The passing of ethical review is a necessary conditions and prerequisite for the development of life science and medical research involving humans. At present, some medical and health institutions have no or insufficient ethical review capabilities. The lack of ethical review ability has become a bottleneck restricting the development of life science and medical research involving humans. According to documents such as Opinions on Deepening the Reform of the Review and Approval System and Encouraging the Innovation of Pharmaceutical and Medical Devices, Opinions on Strengthening the Ethical Governance of Science and Technology, institutions can entrust competent institutional ethics review committees or regional ethics review committees in writing to conduct ethical review. Entrustment ethical review provides a viable solution for institutions that need to carry out life science and medical research involving humans but do not have an ethics (review) committee or the ethics (review) committee is not competent to review. To conduct the entrustment ethical review, the entrustment between the principal and the trustee is required. According to The Measures for Ethical Review of Life Sciences and Medical Research Involving Humans, if medical and health institutions and their ethical review committees do not accept the formal entrustment to provide the ethical review opinions for other institutions, the local health authorities at or above the county level will impose administrative penalties and sanctions on the relevant institutions and personnel in accordance with the law. Signing the entrustment ethical review contract, implementing legal compliance entrusted ethical review to protect the rights and interests of the trustee and the principal, and protect the research participants.

Objective:To explore the differential expression profile of miRN in the development of diabetes nephropathy (DN), and further explore the mechanism of miR-126-5p involved in high glucose induced injury of renal tubular epithelial cells.Methods:Firstly, we downloaded existing chip data from the Gene Expression Integrated Database (GEO) and used GEO2R, miRanda, gene ontology (GO) analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis to mine differential miRNAs. Subsequently, a high glucose induced HK-2 cell injury model was used and divided into three groups: high glucose model group, si-HOTAIR group, and si HOTAIR+ miR-126-5p inhibitor group. The three groups of cells were sequentially transfected with siRNA-NC, siRNA-HOTAIR, and siRNA-HOTAIR+ miR-126-5p mimic, and cultured in a medium containing 60 mmol/L glucose. Flow cytometry was used to detect changes in apoptosis levels in each group, while cell counting kit-8 (CCK-8) was used to detect changes in cell proliferation.Results:Through data mining analysis using GEO, it was found that compared to ordinary mice, DN mice had 74 upregulated miRNAs and 80 downregulated miRNAs in their kidney tissue. Enrichment analysis results showed that miRNAs could target signaling pathways such as Wnt, PKG, MAPK, and Rap1, and miR-126-5p was significantly downregulated. In the high glucose induced HK-2 cell injury model, the experimental results showed that the inhibitory effect on cell proliferation activity was more significant at a high glucose concentration of 60 mmol/L ( P<0.05); High glucose stimulation significantly reduced the expression of miR-126-5p ( P<0.05). The results of flow cytometry showed that compared with the high glucose model group, the apoptosis rate of the si-HOTAIR group significantly decreased ( P<0.05), while the apoptosis rate of the si-HOTAIR+ miR-126-5p inhibitor group significantly increased ( P<0.05). The CCK-8 experiment showed that compared with the high glucose model group, the cell viability of the si-HOTAIR group significantly increased ( P<0.05); The cell viability of the si-HOTAIR+ miR-126-5p inhibitor group was inhibited ( P<0.05). Conclusions:miR-126-5p can inhibit high glucose induced apoptosis in HK-2 cells and protect them.
