This study aimed to investigate the effects of the peptide secreted protein isthmin-1 (ISM1) on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) cells. ISM1 expression in NSCLC was detected by immunohistochemistry (IHC). ISM1 was overexpressed in lung cancer cell lines by transient transfection of ISM1 plasmids, or establishing ISM1 overexpression stable cell lines, or by treating cells with recombined ISM1 (rISM1). CCK-8 was used to examine cell growth. The intracellular signal transduction pathways regulated by rISM1 were analyzed by transcriptome sequencing, and verified by qRT-PCR and Western blot. The levels of intracellular ROS and apoptosis were further detected using the kit. The results showed that the expression of ISM1 was decreased in human NSCLC tissue samples compared to normal lung tissue samples. Overexpression of ISM1 or rISM1 treatment significantly suppressed the growth of lung cancer cells. RNA sequencing revealed that rISM1 mainly regulated the FoxO signaling pathway. rISM1 treatment decreased the expression of FoxO3 and FoxO1, increased reactive oxygen species (ROS) production, and induced cell apoptosis. These results suggest that ISM1 can inhibit the growth of NSCLC by regulating the FoxO signaling pathway. These findings provide new strategies for cancer therapy.

Objective To assess the echogenicity of the ultrasound-guided catheter and its associated delivery system. Methods The study consisted of in vitro characterization experiments and animal studies. In the in vitro phase, the acoustic and mechanical properties of the ultrasound-guided catheter were compared with those of the traditional MPA2 catheter, including parameters such as echo intensity, recognizability, and angle dependence. In the animal experiments, a ventricular septal defect (VSD) model was established in miniature pigs to compare the procedural performance of the ultrasound-guided delivery system versus the conventional system. Evaluation indicators included the time required for the system to cross the VSD, the detection rate of the system within the right ventricle, and the occurrence of intraoperative complications. Results The ultrasound-guided catheter demonstrated a significantly higher mean echo intensity than the MPA2 catheter [(237.3±1.8) dB vs. (190.9±13.1) dB, P<0.001] and a markedly improved recognizability rate (82.3%±5.6% vs. 26.7%±3.2%, P<0.001), along with better angle independence and image quality. In animal experiments, the ultrasound-guided delivery system significantly reduced the time required to cross the VSD [(18.5±5.7) min vs. (30.3±4.5) min, P<0.001] and substantially increased the detection rate within the right ventricle (100.0% vs. 30.0%). No severe complications occurred in any experimental animal. Conclusion The ultrasound-guided catheter and its corresponding delivery system exhibite superior ultrasound visibility and operational performance in both in vitro and animal experiments, indicating strong potential for clinical application.

Objective To analyze and compare the disease burden of high BMI in Kunshan City in different periods, and to provide a scientific basis for the prevention and control of overweight and obesity in Kunshan City. Methods Using the global burden of disease research method, the number of deaths attributable to high BMI and attributable YLL in Kunshan City were calculated using the survey data of chronic diseases and their risk factors and the data of the death registration system in Kunshan City. Results In 2023, R5.46% of deaths in Kunshan City were attributed to high BMI, with 345 attributable deaths, and attributable mortality rate and standardized attributable mortality rate were 39.16/100 000 and 33.82/100 000, Rrespectively. Attributable YLL rate and standardized attributable YLL rate were 692.35/100 000 and 604.46/100 000, respectively. High BMI caused a loss of 0.52 years of life expectancy per capita. Compared with 2012, PAF, standardized attributable mortality rate, standardized attributable YLL rate and life expectancy loss per capita of high BMI in 2023 increased by 121.95%, 100.71%, 57.05%, and 100%, respectively. Among different genders, PAF increased by 91.05% for males and 161.97% for females from 2012 to 2023. Among different diseases, cardiovascular and cerebrovascular diseases and cancers had the highest attributable disease burden, while diabetes, chronic kidney disease and Alzheimer's disease all had a significant increase. Conclusion The burden of disease attributable to high BMI has risen dramatically in Kunshan City, and the adverse health effects of overweight and obesity need to be reduced through scientific weight loss and comprehensive practical measures.

Objective: To investigate the impact of milk and egg supplementation on body composition and bone mineral density of rural primary school students in Yunnan Province, so as to provide a reference for developing targeted nutritional intervention strategies. Methods: In December 2023, a cluster sampling method was adopted to select students from grades one to three in four primary schools each from Jinggu and Shidian countys of Yunnan Province, as the intervention group (662 students). Additionally, two boarding primary schools were selected from each county based on the principle of matching scale and student numbers as the control group (455 students). Starting from April 2023, the intervention group received 200 mL milk and 50 g eggs during the break on school days for 8 months, while the control group maintained their usual diet behavior. Body composition was measured by using bioelectrical impedance analysis, and distal radial bone mineral density was assessed via dual energy X-ray absorptiometry in April and December 2023. The intervention effects were analyzed by using a difference in-differences approach. Results: The final measurements of body fat percentage, skeletal muscle mass and fat free mass of the intervention group and the control group of primary school students were significantly higher than the baseline values, and the net effect of milk and egg intervention on these body composition indicators was not statistically significant ( P >0.05, both before and after adjustment). In contrast, bone mineral density increased significantly by 0.02 g/cm 2 in the intervention group. The net intervention effect on bone mineral density was statistically significant ( β=0.02, 95%CI =0.00-0.04), and remained significant after model adjustment ( β=0.02, 95%CI =0.00-0.04) (both P < 0.05). Subgroup analysis showed statistically significant effects of the intervention among girls ( β=0.02, 95%CI =0.00-0.04), day students ( β=0.04, 95%CI =0.01-0.07), and students with normal nutritional status ( β=0.02, 95%CI =0.00-0.04) (all P <0.05). No significant effect of milk and egg supplementation was observed on body composition indicators (all P <0.05). Conclusions Milk and egg supplementation can improve bone mineral density among rural primary school students in Yunnan Province. It is recommended that rural school aged children should increase intake of milk and eggs to support growth and development.

OBJECTIVE: To observe the clinical effect of Tiaoshen Guben holistic therapy of acupuncture and moxibustion (holistic treatment with acupuncture and moxibustion by adjusting the mind and consolidating the root) on comorbidity of depression and insomnia. METHODS: Twenty-four patients with comorbidity of depression and insomnia were included and treated with Tiaoshen Guben holistic therapy of acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Guanyuan (CV4), bilateral Neiguan (PC6), etc. The refined moxibustion therapy was delivered at Zhongwan (CV12), Qihai (CV6), bilateral Yongquan (KI1), etc. Subcutaneous embedding therapy with thumb-tack needle was adopted at bilateral Xinshu (BL15), bilateral Pishu (BL20), etc. The intervention was operated once every other day, 3 treatments a week, and for 6 consecutive weeks. Before and after treatment completion, and in 1 month after treatment, Pittsburgh sleep quality index (PSQI) and Hamilton's depression scale (HAMD-17) were adopted to assess sleep quality and depression symptoms in the patients, respectively. Before and after treatment completion, using functional magnetic resonance imaging (fMRI), the functional connectivity (FC) of locus coeruleus (LC) in brain regions was evaluated; and the levels of serum norepinephrine (NE), cortisol (CORT), adrenocorticotropic hormone (ACTH) and corticotropin releasing hormone (CRH) were detected. RESULTS: Compared with the scores before treatment, PSQI and HAMD-17 scores after treatment completion and in 1 month after treatment were reduced (P<0.01); and strengthened FC was revealed between the right LC and the pars opercularis of the left inferior frontal gyrus, as well as the lateral occipital lobe region. After treatment completion, serum NE was elevated (P<0.01), the levels of CORT, ACTH and CRH were reduced (P<0.01). Before and after treatment completion, the difference in FC between the right LC and the pars opercularis of the left inferior frontal gyrus was negatively correlated with the differences in PSQI score (r = -0.484, P = 0.016) and HAMD-17 score (r = -0.233, P = 0.027). CONCLUSION Tiaoshen Guben holistic therapy of acupuncture and moxibustion can effectively alleviate depression symptoms and improve sleep quality in the patients with comorbidity of depression and insomnia, which is obtained probably through reducing the levels of serum CORT, ACTH and CRH, increasing serum NE, strengthening the FC of the right LC with the pars opercularis of the left inferior frontal gyrus and the lateral occipital lobe region.

Objective:To investigate the pathways involved in bisphenol S(BPS)and bisphenol F(BPF)induced male reproductive injury by bioinformatics methods and experimental verification.Methods:Bioinformatics analysis was conducted to screen the genes related to male reproductive system diseases associated with BPF and BPS from the Comparative Toxicogenomics Database(CTD).Functional enrichment using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed to predict potential signaling pathways and key genes.Cell counting kit-8(CCK-8)method was used to assess the cell viability in various groups treated with different concentrations of BPS and BPF(1×10-3,1×10-2,1×10-1,1×100,1×101,and 1×102 μmol·L-1).TM3 cells were divided into control group(0.1％DMSO),different doses of BPS groups,and different doses of BPF groups.The cells were treated with 20,40,and 80 μmol·L-1 of BPS and BPF for 72 h,respectively.Real-time fluorescence quantitative PCR(RT-qPCR)and Western blotting method were used to detect the expression levels of key genes mRNA and proteins in various groups.Results:The bioinformatics analysis results revealed that 507 and 447 male systemic disease genes related to BPS and BPF were screened by CTD,respectively.The GO enrichment analysis results showed that the selected genes were primarily enriched in biological processes(BP)such as reproductive system development and reproductive structure development.The KEGG pathway analysis results indicated that these genes were significantly enriched in signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT),hypoxia-inducible factor-1(HIF-1),and cellular senescence(P＜0.001).The CCK-8 method results showed that compared with control group,the cell viabilities in 1× 102 μmol·L-1 BPF and BPS groups were significantly decreased(P＜0.05),while the viabilities of TM3 cells in other groups had no significant changes(P＞0.05).After BPS treatment,compared with control group,the expression levels of PI3K,AKT,hypoxia-inducible factor-1α(HIF-1α),and CREB-binding protein(CBP)mRNA in low,medium,and high doses of BPS groups were decreased(P＜0.05),the expression levels of PI3K protein were decreased(P＜0.05),the expression levels of B-cell lymphoma-2-associated X protein(Bax)protein were increased(P＜0.05),and the expression levels of serine protease inhibitor clade B,member 10(SERPINB10)mRNA were increased(P＜0.01);the expression levels of Bax and intraflagellar transport 80 homolog(IFT80)mRNA in the cells in medium and high doses of BPS groups were increased(P＜0.05);the expression levels of B-cell lymphoma-2(Bcl-2)mRNA and protein in low and high doses of BPS groups were decreased(P＜0.05);the expression levels of additional sex combs like 2(ASXL2)mRNA in low and medium doses of BPS groups were decreased(P＜0.01).After BPF treatment,compared with control group,the expression levels of Bcl-2,HIF-1α,and structural maintenance of chromosomes protein 1B(SMC1B)mRNA in low,medium,and high doses of BPF groups were decreased(P＜0.05),and the expression levels of IFT80 mRNA(P＜0.01)and Bax protein(P＜0.01)were increased;the expression levels of PI3K,AKT,and ring finger protein 130(RNF130)mRNA in low and high doses of BPF groups were decreased(P＜0.05);the expression level of CBP mRNA in medium dose of BPF group was decreased(P＜0.05),while the expression level of RNF130 mRNA was increased(P＜0.05);the expression levels of PI3K and Bcl-2 proteins in high dose of BPF group were decreased(P＜0.05).Conclusion:BPF and BPS may cause cell cytotoxicity and impair male reproductive health through PI3K/AKT and HIF-1 signaling pathways.RNF130 and SMC1B may be important targets for their induction of male reproductive toxicity.

ObjectiveTo explore the potential mechanism of acupuncture with the method of soothing the liver and regulating the mind in improving depressive disorder. MethodsEighteen C57BL/6J mice were randomly divided into blank group， model group， and acupuncture group， with 6 mice in each group. The model group and the acupuncture group were subjected to depression induction by intraperitoneal injection of lipopolysaccharide （LPS）， while the blank group received an equal volume of normal saline once daily for seven consecutive days. Concurrently， the acupuncture group received "soothing the liver and regulating the mind" acupuncture intervention starting from the first day of modeling， once daily for 14 days； whereas the blank group and the model group were only restrained without acupuncture. The sucrose preference test was used to assess sucrose preference rate， the open-field test to measure center stay time and total travel distance， and the forced swim test to evaluate immobility time. Hematoxylin-eosin （HE） staining was performed to observe hippocampal morphological changes. Enzyme-linked immunosorbent assay （ELISA） was used to detect levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in hippocampal tissue. Western blot analysis was conducted to examine the protein expression levels of Toll-like receptor 4 （TLR4） and nuclear factor-κB （NF-κB） in the hippocampus. ResultsCompared to the blank group， the model group showed a significant reduction in sucrose preference rate， center stay time， and total travel distance， along with a significant increase in immobility time in the forced swim test， hippocampal IL-1β， IL-6， and TNF-α levels， as well as TLR4 and NF-κB protein expression （P＜0.01）， and the histological examination revealed blurred hippocampal neuronal boundaries， loose arrangement， and some neurons exhibiting nuclear pyknosis and deep staining. Compared to the model group， the acupuncture group demonstrated a significant increase in sucrose preference rate， center stay time， and total travel distance， along with a significant reduction in immobility time in the forced swim test， hippocampal IL-1β， IL-6， and TNF-α levels， and TLR4 and NF-κB protein expression （P＜0.01）， and the histological analysis showed that hippocampal neurons in the acupuncture group were more tightly arranged， with reduced nuclear pyknosis and deep staining. ConclusionAcupuncture with the "soothing the liver and regulating the mind" method can significantly improve depression-like behavior， potentially by inhibiting the hippocampal TLR4/NF-κB signaling pathway and alleviating inflammatory responses.

Objective To investigate the clinical and MRI imaging features of ovarian endometrioid adenofibroma and to analyze its pathological features in order to promote the diagnostic and differential diagnostic ability.Methods The clinical and MRI imaging features of 5 cases of ovarian endometrioid adenofibroma confirmed by pathology were analyzed retrospectively.Results Among the 5 patients,2 were diagnosed with postmenopausal vaginal bleeding,while the other 3 cases were incidental findings with no obvious clinical discomfort.One patient had elevated estrogen level,but the remaining patients showed no obvious abnormalities in laboratory examinations.All the lesions in 5 patients were cystic-solid masses,MRI showed mixed iso-and hypointensity on T1 WI,and slightly hyperintensity and hypointensity of solid components on T2WI.The solid components showed scattered cystic foci with smooth cyst walls and partial septa.The signal in the capsule was homogeneous.Diffusion weighted imaging(DWI)showed slightly hyperintensity and hypointensity.Contrast-enhanced scans showed gradual enhancement in the solid part of the massed with no enhancement in the cystic areas.Conclusion The clinical manifestations of ovarian endometrioid adenofibroma are non-specific,but MRI manifestations are specific to some extent.The final diagnosis depends on pathological diagnosis.
