Male factors contribute to 50% of infertility cases, with 20%-30% of cases being solely attributed to male infertility. Helicase for meiosis 1 ( HFM1 ) plays a crucial role in ensuring proper crossover formation and synapsis of homologous chromosomes during meiosis, an essential process in gametogenesis. HFM1 gene mutations are associated with male infertility, particularly in cases of non-obstructive azoospermia and severe oligozoospermia. However, the effects of intracytoplasmic sperm injection (ICSI) in HFM1 -related infertility cases remain inadequately explored. This study identified novel biallelic HFM1 variants through whole-exome sequencing (WES) in a Chinese patient with severe oligozoospermia, which was confirmed by Sanger sequencing. The pathogenicity of these variants was assessed using real-time quantitative polymerase chain reaction (RT-qPCR) and immunoblotting, which revealed a significant reduction in HFM1 mRNA and protein levels in spermatozoa compared to those in a healthy control. Transmission electron microscopy revealed morphological abnormalities in sperm cells, including defects in the head and flagellum. Despite these abnormalities, ICSI treatment resulted in a favorable fertility outcome for the patient, indicating that assisted reproductive techniques (ART) can be effective in managing HFM1 -related male infertility. These findings offer valuable insights into the management of such cases.

OBJECTIVES: To investigate the mechanism of DDX17 for regulating proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) during the development of pulmonary hypertension (PH). METHODS: In murine PASMCs cultured under normoxic or hypoxic conditions, the effects of transfection with si-Ddx17 and insulin treatment, alone or in combination, on cell proliferation and migration were evaluated using Ki-67 immunofluorescence staining, scratch assay and Transwell assay. Western Blotting was performed to detect the changes in protein expression levels of DDX17, 4EBP1, S6, p-4EBP1, and p-S6. In a mouse model of PH induced by intraperitoneal injection of monocrotaline (MCT), the changes in pulmonary vasculature were examined using HE staining following tail vein injection of AD-Ddx17i. RESULTS: The PASMCs in hypoxic culture exhibited significantly enhanced cell proliferation and migration and protein expressions of p-4EBP1 and p-S6, and these changes were obviously reversed by transfection with si-Ddx17. Treatment with insulin significantly attenuated the effect of si-Ddx17 against hypoxic exposure-induced changes in PASMCs. In the mouse model of MCT-induced PH, transfection with AD-Ddx17i obviously alleviated pulmonary vascular stenosis and intimal hyperplasia. CONCLUSIONS The expression of DDX17 is elevated in hypoxia-induced PASMCs and PH mice, and silencing DDX17 significantly inhibits PASMC proliferation and migration in vitro and pulmonary vascular remodeling in PH mice by reducing mTORC1 activity.

The evolution of acupuncture anesthesia (AA) has spanned six decades. Cardiothoracic surgery serves as a representative case study to illustrate this evolution. Reflecting on its historical development, the use of AA in cardiothoracic surgery has advanced from basic AA procedures in the 1960s to combined acupuncture and drug anesthesia techniques in the early 1980s. Since 2005, the innovative use of non-intubation AA combined anesthesia has been implemented extensively in cardiothoracic surgery. As the medical industry continues to evolve, the techniques applied in AA have expanded to encompass the entire perioperative period in cardiothoracic surgery, leading to the introduction of the concept of modern AA. The use of AA in cardiothoracic surgery exemplifies the ongoing advances and integration of traditional Chinese and Western medicine. Moving forward, it is imperative to enhance the theoretical framework of AA through the execution of rigorous multicenter clinical trials, to further strengthen the body of evidence supporting evidence-based medicine, and to finally explore the underlying mechanisms of AA.

OBJECTIVE: This study aimed to evaluate the association between susceptibility genes and non-alcoholic fatty liver disease (NAFLD) in children with obesity. METHODS: We conducted a two-step case-control study. Ninety-three participants were subjected to whole-exome sequencing (exploratory set). Differential genes identified in the small sample were validated in 1,022 participants using multiplex polymerase chain reaction and high-throughput sequencing (validation set). RESULTS: In the exploratory set, 14 genes from the NAFLD-associated pathways were identified. In the validation set, after adjusting for sex, age, and body mass index, ECI2 rs2326408 (dominant model: OR = 1.33, 95% CI: 1.02-1.72; additive model: OR = 1.22, 95% CI: 1.01-1.47), C6orf201 rs659305 (dominant model: OR = 1.30, 95% CI: 1.01-1.69; additive model: OR = 1.21, 95% CI: 1.00-1.45), CALML5 rs10904516 (pre-ad dominant model: OR = 1.36, 95% CI: 1.01-1.83; adjusted dominant model: OR = 1.40, 95% CI: 1.03-1.91; and pre-ad additive model: OR = 1.26, 95% CI: 1.04-1.66) polymorphisms were significantly associated with NAFLD in children with obesity ( P < 0.05). Interaction analysis revealed that the gene-gene interaction model of CALML5 rs10904516, COX11 rs17209882, and SCD5 rs3733228 was optional ( P < 0.05), demonstrating a negative interaction between the three genes. CONCLUSION In the Chinese population, the CALML5 rs10904516, C6orf201 rs659305, and ECI2 rs2326408 variants could be genetic markers for NAFLD susceptibility.

OBJECTIVE: To investigate the spatiotemporal patterns and socioeconomic factors influencing the incidence of tuberculosis (TB) in the Guangdong Province between 2010 and 2019. METHOD: Spatial and temporal variations in TB incidence were mapped using heat maps and hierarchical clustering. Socioenvironmental influencing factors were evaluated using a Bayesian spatiotemporal conditional autoregressive (ST-CAR) model. RESULTS: Annual incidence of TB in Guangdong decreased from 91.85/100,000 in 2010 to 53.06/100,000 in 2019. Spatial hotspots were found in northeastern Guangdong, particularly in Heyuan, Shanwei, and Shantou, while Shenzhen, Dongguan, and Foshan had the lowest rates in the Pearl River Delta. The ST-CAR model showed that the TB risk was lower with higher per capita Gross Domestic Product (GDP) [Relative Risk ( RR), 0.91; 95% Confidence Interval ( CI): 0.86-0.98], more the ratio of licensed physicians and physician ( RR, 0.94; 95% CI: 0.90-0.98), and higher per capita public expenditure ( RR, 0.94; 95% CI: 0.90-0.97), with a marginal effect of population density ( RR, 0.86; 95% CI: 0.86-1.00). CONCLUSION The incidence of TB in Guangdong varies spatially and temporally. Areas with poor economic conditions and insufficient healthcare resources are at an increased risk of TB infection. Strategies focusing on equitable health resource distribution and economic development are the key to TB control.

Objective To explore the role and possible molecular mechanism of Isocitrate dehydrogenase 1(IDH1)gene in proliferation and migration of intrahepatic cholangiocarcinoma(iCCA)cell HuCCT1.Methods HuCCT1 cells with IDH1 gene knockout(HuCCT1IDH1-/-)were constructed by CRISPR/Cas9 gene editing technology.To investigate the capacities of proliferation,migration and invasion of HuCCT1WT(HuCCT1 cells with wild-type IDH1 gene)and HuCCT1IDH1-/-cells,assays of CCK-8,clone formation,scratch and transwell were performed.Western blotting was used to detect the expression levels of epithelial-mesenchymal transition(EMT)associated proteins E-cadherin,N-cadherin,Vimentin,MMP-9,Wnt3a and β-catenin in two groups of cells.The transcriptome sequencing data of HuCCT1WT and HuCCT1IDH1-/-cells were analyzed by bioinformatics methods,Western blotting was used to verify the expression of signaling pathway-related proteins.Results Compared with HuCCT1WT cells,HuCCT1IDH1-/-cells showed the number of proliferation and clone formation significantly reduced(P<0.05),the proportion of cells blocked in G2/M phase was significantly increased(P<0.01),the rate of scratch healing was significantly decreased(P<0.01),and the number of migrated cells(P<0.001)and invaded cells(P<0.05)was significantly reduced.qRT-PCR assay showed that the expression levels of IDH1,Vimentin,MMP-9 and genes related to the regulation of G2/M cycle proliferation,Cyclin A2,Cyclin B1 and CDK1 mRNA were down-regulated in HuCCT1IDH1-/-cells(P<0.05),and the expression of CDH1 mRNA encoding E-cadherin was up-regulated(P<0.01);Western blotting assay showed that the expression level of E-cadherin in HuCCT1IDH1-/-cells was significantly increased(P<0.05),and the expression level of N-cadherin,Vimentin and MMP-9 protein was significantly decreased(P<0.05)than that in HuCCT1WT cells.Data of transcriptome sequencing revealed 1476 differentially expressed genes(DEGs)between two groups of HuCCT1 cells.Go enrichment analysis showed the DEGs were significantly enriched in cell biological processes associated with inflammatory response,cell signaling and cell metabolism.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis suggested that the DEGs may be involved in some signaling pathways such as Wnt,MAPK,Rap1,Hippo and TNF,which are closely related to the regulation of proliferation and invasion of tumor cells.Western blotting verification results showed that compared with HuCCT1WT cells,the relative expression of Wnt3a and β-catenin proteins of HuCCT1IDH1-/-cells was significantly decreased(P<0.05).Conclusions IDH1 gene may participate in the control of biological functions of HuCCT1 cells,including cell proliferation,migration,invasion and epithelial mesenchymal transition.The mechanism may be related to the activation of the Wnt/β-catenin signaling pathway.

Pulmonary disease is one of the major threats to human health. However, the current clinical treatment drugs for lung diseases generally have problems such as low lung delivery efficiency, fast clearance rate and obvious toxic side effects. Recently, membrane biomimetic nanocarriers have attracted more and more attention. Due to their advantages of high targeting, long cycle time, good biocompatibility and strong immune escape ability, membrane biomimetic nanocarriers have become a major research hotspot in targeted therapy of lung diseases. In this review, we discuss the main preparation methods of membrane biomimetic nanoparticles, the characteristics of membrane biomimetic nanocarriers from different cell sources and their application in the targeted therapy of lung diseases. At the same time, according to the characteristics of different membranes, the shortcomings, current technical limitations and future prospects are discussed. This review is expected to provide references for the design of membrane biomimetic nanocarriers and their potential applications in the treatment of lung diseases.

Misuse of pyrrolizidine alkaloid (PA)-containing herbs is the major cause of hepatic sinusoidal obstruction syndrome (HSOS) in China. And diuretics are among the most commonly used medications for the treatment of PA-induced HSOS in clinical practice. As a traditional diuretic in traditional Chinese medicine, the diuretic mechanism of Alismatis Rhizoma (AR) has not been fully clarified, and there is no report on AR ameliorating PA-induced HSOS from a diuretic point of view. Therefore, this study aims to investigate the therapeutic potential of alisol B 23-acetate (AB23A) against acute liver injury induced by senecionine (a representative toxic PA) in mice, and to further elucidate its effect on impaired water-liquid balance in mice exposed to PA. All experiments were approved by the Animal Research Committee of Shanghai University of Traditional Chinese Medicine (Registration number: PZSHUTCM220808017). Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Shanghai University of Traditional Chinese Medicine. Model of mice was induced by a single oral exposure of senecioine (50 mg·kg^-1) (SEN group), and AB23A (40 mg·kg^-1) intervention group (AB23A+SEN group), solvent control group (Ctrl group) and AB23A control group (AB23A group) were set up. The results showed that AB23A could significantly attenuate the levels of serum biochemical indices of liver functions in senecioine-induced acute liver injury mice, as evident by alleviated hepatocyte necrosis and hepatic sinusoidal stasis. AB23A also improved kidney function of mice exposed to senecionine, fascinated urinary excretion and repaired electrolyte disorders, as well as decreased content of senecioine metabolites. Further, the protein and mRNA expression of genes related to the water balance pathway were measured. AB23A could significantly down-regulate the elevated protein and mRNA expression levels of aquaporin 2 (AQP2) and angiotensin II type 1 receptor, and inhibit the transport of AQP2 to the apical plasma membrane induced by senecionine exposure. AB23A also significantly decreased serum levels of angiotensin II. In vitro studies further confirmed that AB23A regulates AQP2 expression in renal inner medullary collecting duct cells 3 (IMCD3). These data indicate that AB23A regulates the expression of AQP2 in renal medulla, thereby affecting its water reabsorption in mice with senecionine-induced acute liver injury. This work achieves a better understanding of the diuretic effect of AR, and provides experimental foundation and theoretical basis for the treatment of PA-induced acute liver injury by AR in clinics.

Aim To explore the role of Takeda G pro-tein-coupled receptor 5(TGR5)in the proliferation and migration of vascular smooth muscle cells(VSMCs)within the intimal layer of mice.Methods Mouse VSMCs were stimulated for proliferation and migration with PDGF-BB,followed by administration of INT-777 for activation of TGR5.CCK-8 assay and Ki-67 immunofluorescence staining were employed to eval-uate cell proliferation.The scratch assay was utilized to assess migration.Western blot analysis was conducted to monitor TGR5 protein expression.To further investi-gate the role of TGR5 in intimal hyperplasia in vivo,20 male wild-type C57BL/6J mice were randomly divided into four groups:sham group,carotid artery endothelial injury group,sham+UDCA(ursodeoxy-cholic acid,a TGR5 agonist)group,and carotid artery endothelial injury+UDCA group(n=5 in each group).After the establishment of endothelial injury model,mice were orally fed with regular maintenance feed containing 0.5％UDCA for 21 days.Subsequent-ly,samples were collected for Hematoxylin and Eosin(HE)staining to assess the neointimal hyperplasia.Immunofluorescence(IF)staining was used to exam-ine the proliferation of VSMCs within the carotid inti-ma.Results The specific activation of TGR5 marked-ly diminished cell viability,the proportion of Ki-67-positive cells,and slowed down the rate of wound-heal-ing.Notably,the specific activation of TGR5 increases the expression of UCP2 in cells and reduces the levels of reactive oxygen species(ROS).The inhibitory effect of TGR5 on VSMC proliferation and migration was neutralized upon the restoration of intracellular ROS level with H2O2.Activation of TGR5 was found to mitigate intimal thickening following carotid artery inju-ry.Conclusion TGR5 may inhibit the proliferation and migration of mouse VSMCs by attenuating intracel-lular oxidative stress.

Objective To investigate the equivalent conversion of head injury criterion(HIC)under anterior-posterior(AP)and lateral-medial(LM)craniocerebral impact for mild craniocerebral injury in rats using motor evoked potential(MEP)and β-amyloid precursor protein(β-APP)immunohistochemistry(IHC).Methods Sixty healthy adult male SD rats were randomly divided into 0 m control group,0.5 m-AP and 0.5 m-LM injury groups,and 1 m-AP and 1 m-LM injury groups(12 rats in each group).The control group did not undergo any impact injury experiment.After the impact injury experiment,the injury and control groups were subjected to excessive anesthesia to produce β-APP immunohistochemical stained slices,and the percentage of positive area and integral optical density(IOD)in the brainstem pyramidal tract area of the slices were determined.The MEP groups were divided in the same manner as the IHC groups and the MEP amplitudes of the MEP and control groups were measured after the impact injury experiment.Results With an increase in the degree of injury,the decrease in MEP amplitude,percentage of positive areas,and IOD in the injury groups significantly increased.When the degree of injury was low,the sensitivity of IHC was higher than that of MEP.When the degree of injury was the same,the HIC in the LM direction was lower than that in the AP direction.When the HIC was the same,the degree of injury in the LM direction was greater than that in the AP direction.Conclusions The joint evaluation of MEP and β-APP can provide experimental references for the study of HIC equivalent conversion in AP-LM craniocerebral impact injury.
