The liver, skeletal muscle, and adipose tissue are central energy-metabolizing organs and insulin-sensitive tissues, playing a crucial role in maintaining glucose homeostasis. As the powerhouse of the cell, mitochondria not only regulate insulin secretion but also oversee the oxidative phosphorylation and β-oxidation of fatty acids, processes vital for the metabolism of carbohydrates and fats, as well as the synthesis of ATP. The mitochondrial quality control system is of paramount importance for sustaining mitochondrial homeostasis, achieved through mechanisms such as protein homeostasis, mitochondrial dynamics, mitophagy, and biogenesis. Evidence suggests that dysfunctional mitochondria may significantly contribute to insulin resistance and ectopic fat storage in the liver, offering new insights into the strong correlation between mitochondrial dysfunction and the development of obesity, diabetes mellitus type 2 (T2DM), and non-alcoholic fatty liver disease (NAFLD). This manuscript aims to delve into the precise mechanisms by which imbalances in mitochondrial quality control lead to metabolic disorders in the liver, skeletal muscle, and adipose tissue, the 3 major insulin-sensitive organs. In the liver, mitochondrial dysfunction can lead to disturbances in glucose and lipid metabolism, resulting in insulin resistance and fat accumulation—a key factor in the development of NAFLD. In skeletal muscle, reduced mitochondrial function can decrease ATP production, weakening the muscle’s ability to uptake glucose, thereby exacerbating insulin resistance. In adipose tissue, mitochondrial dysfunction can impair adipocyte function, leading to lipotoxicity and inflammatory responses,which further contribute to insulin resistance and the onset of metabolic syndrome. Moreover, the interorgan crosstalk among these 3 tissues is essential for overall metabolic homeostasis. For instance, hepatic gluconeogenesis and glucose utilization in skeletal muscle are both influenced by the health status of their respective mitochondrial populations. The conversion between different types of adipose tissue and the ability to store lipids depend on normal mitochondrial function to avert ectopic fat accumulation in other organs. In summary, this manuscript emphasizes the critical role of mitochondrial quality control in maintaining the metabolic stability of the liver, skeletal muscle, and adipose tissue. It elucidates the specific mechanisms by which mitochondrial dysfunction in these organs contributes to the development of metabolic diseases, providing a foundation for future research and the development of therapeutic strategies targeting mitochondrial dysfunction.

OBJECTIVE: To explore the clinical application value of metagenomic next-generation sequencing (mNGS) in pathogen detection of bloodstream infection secondary to hematologic diseases in children. METHODS: 42 children with bloodstream infections secondary to hematologic diseases admitted to the Children's Hematology and Tumor Center of the Affiliated Hospital of Guangdong Medical University from November 2021 to May 2023 were included in the study, and their clinical data, results of peripheral blood mNGS and traditional blood culture, pathogen distribution characteristics, and diagnostic efficacy of mNGS were retrospectively analyzed. RESULTS: Among the 42 children included, there were 2 cases (4.8%) of aplastic anemia (AA), 27 cases (64.3%) of acute lymphoblastic leukemia (ALL), 7 cases (16.7%) of acute myeloid leukemia (AML), 1 case (2.4%) of chronic myeloid leukemia (CML), 2 cases (4.8%) of hemophagocytic lymphohistiocytosis (HLH), 2 cases (4.8%) of non-Hodgkin lymphoma (NHL), and 1 case (2.4%) of Wiskott-Aldrich syndrome (WAS). In mNGS testing, pathogens were detected in 31 peripheral blood samples, with a positive rate of 73.8% (31/42), significantly higher than the pathogen positive rate of 16.7% (7/42) detected by traditional blood culture, and the difference was statistically significant (P < 0.05). Among the pathogen-positive cases detected by mNGS, 23 cases (74.2%) were positive for bacteria, 12 cases (38.7%) were positive for viruses, and 9 cases (29.0%) were positive for fungi. 32.2% (10/31) of the pathogen-positive samples detected by mNGS were mixed pathogens, which could not be effectively detected by traditional blood culture. CONCLUSION Peripheral blood mNGS has advantages in the detection of pathogens of bloodstream infection secondary to hematologic diseases, with a higher detection rate of pathogen positivity than traditional blood cultures. It can detect viruses, rare pathogens and mixed pathogens, and has good clinical application value.

OBJECTIVE: To explore the association between acupuncture during controlled ovarian hyperstimulation (COH) and the live birth rate (LBR) using different propensity score methods. METHODS: In this retrospective cohort study, eligible women who underwent a COH were divided into acupuncture and non-acupuncture groups. The primary outcome was LBR, as determined by propensity score matching (PSM). LBR was defined as the delivery of one or more living infants that reached a gestational age over 28 weeks after embryo transfer. The propensity score model encompassed 16 confounding variables. To validate the results, sensitivity analyses were conducted using three additional propensity score methods: propensity score adjustment, inverse probability weighting (IPW), and IPW with a "doubly robust" estimator. RESULTS: The primary cohort encompassed 9751 patients (1830 [18.76%] in the acupuncture group and 7921 [81.23%] in the non-acupuncture group). Following 1:1 PSM, a higher LBR was found in the acupuncture cohort (41.4% [755/1824] vs 36.4% [664/1824], with an odds ratio of 1.23 [95% confidence interval, 1.08-1.41]). Three additional propensity score methods produced essentially similar results. The risk of serious adverse events did not significantly differ between the two groups. CONCLUSION This retrospective study revealed an association between acupuncture and an increased LBR among patients undergoing COH, and that acupuncture is a safe and valuable treatment option.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To identify genetic regulators of ionizing radiation(IR)sensitivity through clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated nuclease 9(Cas9)genome-wide screening.Methods A specialized single guide RNA(sgRNA)library was developed targeting 987 stress-response regulatory genes identified through Kyoto Encyclopedia of Genes and Genomes(KEGG),Reactome and gene ontology(GO)databases,followed by construction of sgRNA plasmids and packaging into a lentiviral library.Using colon adenocarcinoma Caco-2 cells as a model system,the Cas9-stable transgenic line was established via lentiviral transduction and antibiotic selection.Library-transduced cells underwent puromycin selection,followed by γ-irradiation(dose optimized via preliminary experiments).Post-irradiation phenotypic selection was conducted after 14 days,with subsequent next-generation sequencing of surviving cell populations to identify enriched/depleted sgRNAs.Candidate genes were functionally validated through orthogonal assays:cell counting kit-8(CCK-8)proliferation analysis,clonogenic survival assays and flow cytometric quantification of reactive oxygen species(ROS)and apoptotic markers.Results The optimized screening platform identified 281 radiation response genes(165 radiosensitive and 116 radioprotective candidates).Functional validation revealed Bcl2-associated athanogene 3(BAG3)knockdown significantly enhanced radioresistance.Proliferation was increased 1.2-1.5 fold,clonogenic survival improved 1.5-2.0 fold,and ROS was reduced by 13％-25％coupled with 32％-73％apoptosis attenuation compared to control groups.Conclusion The integrated CRISPR/Cas9 screening platform effectively identifies novel radiation response regulators,as evidenced by the discovery of BAG3 as a critical radiosensitivity determinant.This high-throughput functional genomics approach provides a robust methodology for systematically mapping molecular determinants of cellular radiation response,with potential applications in both mechanistic studies and therapeutic target discovery.

Objective To classify traumatic triangular fibrocartilage complex(TFCC)injury based on 3.0T MR.Methods A total of 46 patients with definite history of wrist trauma admitted were collected.All patients underwent MRI scanning within 3 days after trauma,and the MRI findings were classified as follows according to the Palmer classification criteria:the focal structures of triangular fibro-cartilage(articular disc)(TFC)injury,the horizontal of the articular disc tear,injuries of ulnar styloid attachment and ulnar fovea attach-ment in TFC,ulnolunate and ulnotriquetral ligaments injuries,injury of the radial sigmoid notch junction,meniscal homologous inju-ry.The presence of TFCC injury was eventually confirmed by surgery in all patients.Results Of 46 patients,38 patients could be classified by Palmer,and there were 10 cases with type ⅠA,23 cases with type ⅠB,3 cases with type ⅠC and 2 cases with type ⅠD.A total of 8 patients were not suitable for Palmer type,and there were 3 patients with horizontal tears in the articular disc and 5 patients with meniscus homologous injuries.Conclusion The 3.0T MR can not only show various subtypes of Palmer classification,but also refine and supplement the classification based on the original classification,such as the injuries of ulnar styloid attachment and ulnar fovea attachment at the ulnar end of the articular disc,horizontal tear of the articular disc,meniscus homologous injury,etc.

[Objective] To analyze the influencing factors of postoperative patency of longitudinal single suture intussusception microsurgical vasoepididymostomy, to provide reference for improving the repetition rate. [Methods] The clinical data of 82 patients with epididymal obstructive azoospermia who underwent longitudinal single suture intussusception microsurgical vasoepididymostomy in our hospital during Sep.2020 and Jan.2023 were retrospectively analyzed.The postoperative patency and spouse pregnancy were followed up by face to face and / or telephone interview.The effects of age, course of disease, body mass index (BMI), previous medical history (epididymitis, operation history, none), preoperative seminal plasma elastase (SPE) level, anastomosis site, unilateral and bilateral lesion, sperm quality, operation time and hospital stay on the postoperative patency rate were analyzed. [Results] All operations were successful, the follow-up rate was 95.12% (78/82), 78 were married, and the postoperative patency was 78.21% (61/78). Of the 61 patients who achieved patency, 56 were married, and the natural pregnancy rate of spouse was 45.21% (33/73). Univariate analysis showed that patients with age <30 years, course of disease <2 years, preoperative SPE level <290 ng/mL, bilateral anastomosis, body or tail anastomosis and motile sperm had higher postoperative patency rate (P>0.05). BMI, previous history, the number of motile sperms examined by epididymal fluid, the length of operation and hospital stay had no significant effects on postoperative patency (P>0.05). The results of multivariate logistic regression analysis showed that preoperative SPE level (OR=0.998, 95%CI: 0.997-1.000, P=0.008) and (OR=10.724, 95%CI: 2.243-51.283, P=0.003) were significantly correlated with postoperative patency. [Conclusion] The preoperative SPE level and anastomosis site are significant influencing factors of postoperative patency, which is higher in patients with age <30 years, course of disease <2 years, preoperative SPE level <290 ng/mL, bilateral anastomosis, body or tail anastomosis and motile sperm.

Objective To review the research on the application of clinical decision support system(CDSS)involving nurses in depression both domestically and internationally.Methods 10 Chinese and English databases including PubMed,Web of Science,Scopus,CINAHL,PsycINFO,Embase,Cochrane Library,CNKI,Wanfang Database,and VIP were searched until March,2024.The eligible literature of the application of CDSS involving nurses in depression was selected to analyze the basic characteristics of studies,the functions,characteristics,feasibility,and effectiveness of CDSS.Results Finally,16 English articles involving 13 CDSS were included.This study found that nurses participating in CDSS can improve the degree of depression in patients,but its application in depression management is mainly for screening,and few CDSS can propose personalized depression management programs based on the psychological and social factors of patients.Conclusion The CDSS involving nurses can promote the screening of depression and improve depression in patients,but it fails to propose a personalized depression management program.Future research can develop CDSS based on electronic medical record systems to facilitate nurses'screening for depression and further develop an intelligent management module for CDSS to provide intelligent and personalized management solutions for patients with depression.

Objective:To analyze the factors for low libido in male patients with sexual dysfunction and provide some evidence for the clinical diagnosis and treatment of the condition.Methods:We retrospectively analyzed the clinical data on 111 cases of sex-ual dysfunction(including disorders in erection,ejaculation or libido)treated in the Zhengzhou University First Hospital from June to September 2023.According to the patients'complaints of low libido or accompanied symptoms,we divided them into a normal libido group(n=68)and a low libido(n=43),obtained their scores on IIEF-5,Premature Ejaculation Diagnostic Tool(PEDT),13-1-tem Self-Rating Libido Scale for Males(SRLS-M),Patients'Health Questionnaire-9(PHQ-9)and General Anxiety Disorder-7(GAD-7),examined the levels of the sexual hormones FSH,LH,PRL,T,free testosterone(fT),E2,?insulin-like growth factor 1(IGF-1)and growth hormone(GH),compared the basic parameters between the two groups,and analyzed their correlation with the libido values.Results:The IIEF-5,PEDT and libido scores and IGF-1 level were significantly higher and the GAD-7 score remark-ably lower in the normal than in the low libido group(P＜0.05),but no statistically significant differences were observed between the two groups in the PHQ-9 score and the levels FSH,LH,PRL,T,fT,E2,T/E2 and GH(P＞0.05).The libido value was correla-ted positively with the I1EF-5(r=0.28,P＜0.01)and PEDT scores(r=0.29,P＜0.01)and IGF-1 level(r=0.23,P＜0.05),but negatively with the GAD-7 score(r=-0.21,P＜0.05).Conclusion:Low libido results from multiple factors,which cannot be fully explained by sexual hormone levels but is closely related to the decreased level of IGF-1 and severity of ED and anxiety.
