Objective:
To explore the impact of family function intervention on mental health status of middle school students, so as to provide the reference for promoting adolescent mental health.
Methods:
From October 2023 to January 2024, 44 families from grade 2 of one junior high school were recruited. They were randomly divided into an intervention group ( n =21) and a control group ( n =23) using a simple random sampling method. Both groups of families participated in various daily school activities and learning, but the intervention group of families also participated in 10 online family function intervention courses. Family Assessment Device (FAD) and the Middle School Student Mental Health Scale (MSSMHS) were used as evaluation tools. Pearson correlation analysis was used to test the correlation between FAD total scores of middle school students and the total mean scores of MSSMHS, and repeated measures ANOVA was used to analyze FAD scores changes in various dimensions before and after intervention.
Results:
The total score of FAD in middle school students was positively correlated with the total average score of MSSMHS ( r= 0.44, P <0.01). Before intervention, there was no statistically significant difference in the FAD scores (intervention group: 143.19 ±16.05, control group:144.87±22.40) and MSSMHS total average scores (intervention group: 1.69±0.46, control group: 1.77 ±0.59) between the two groups ( t=0.28, 0.53, P >0.05). After intervention, the main effect of time, group, and time group interaction of the interventions on the FAD total scores between the intervention group and the control group were statistically significant ( F=11.87, 7.26, 11.04, P <0.05). Further simple effects analysis revealed that the post test FAD total score of the intervention group (121.71±16.01) decreased by 21.48 points compared to the pre test and was lower than the post test total score of the control group (144.47±17.71), with statistically significant differences ( t=4.68, 4.11, P <0.05). The main effect of the group on the total mean MSSMHS score between the intervention and control groups was statistically significant ( F=8.45, P <0.05), while the main effect of time was not statistically significant ( F=1.68, P >0.05). Further comparative analysis revealed that the post test total mean score of MSSMHS in the intervention group (1.34±0.23) was lower than that in the control group (1.85±0.52) ( t=3.48, P <0.01).
Conclusion
Family function intervention can improve the mental health status of middle school students, and relevant measures should be actively taken to promote adolescent mental health.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back, and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group, with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes, three times per week; the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement, as the primary outcome, was assessed using the Global Pain Scale (GPS) at baseline, after 2 weeks of treatment, and again 2 weeks post-treatment. To explore potential mechanisms, a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration, the between-group mean difference was -8.8 [95% CI (-18.2, -0.7), P<0.05]. Part of the therapeutic effect was mediated by changes in deep muscle elasticity, with a mediation effect size of -1.5 [95% CI (-2.0, -0.9), P = 0.024], accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back, partly through a mediating effect of improved deep muscle elasticity.

The innate immune system detects cellular stressors and microbial infections, activating programmed cell death (PCD) pathways to eliminate intracellular pathogens and maintain homeostasis. Among these pathways, pyroptosis, apoptosis, and necroptosis represent the most characteristic forms of PCD. Although initially regarded as mechanistically distinct, emerging research has revealed significant crosstalk among their signaling cascades. Consequently, the concept of PANoptosis has been proposed—an inflammatory cell death pathway driven by caspases and receptor-interacting protein kinases (RIPKs), and regulated by the PANoptosome, which integrates key features of pyroptosis, apoptosis, and necroptosis. The core mechanism of PANoptosis involves the assembly and activation of the PANoptosome, a macromolecular complex composed of three structural components: sensor proteins, adaptor proteins, and effector proteins. Sensors detect upstream stimuli and transmit signals downstream, recruiting critical molecules via adaptors to form a molecular scaffold. This scaffold activates effectors, triggering intracellular signaling cascades that culminate in PANoptosis. The PANoptosome is regulated by upstream molecules such as interferon regulatory factor 1 (IRF1), transforming growth factor beta-activated kinase 1 (TAK1), and adenosine deaminase acting on RNA 1 (ADAR1), which function as molecular switches to control PANoptosis. Targeting these switches represents a promising therapeutic strategy. Furthermore, PANoptosis is influenced by organelle functions, including those of the mitochondria, endoplasmic reticulum, and lysosomes, highlighting organelle-targeted interventions as effective regulatory approaches. Cardiovascular diseases (CVDs), the leading global cause of morbidity and mortality, are profoundly impacted by PCD. Extensive crosstalk among multiple cell death pathways in CVDs suggests a complex regulatory network. As a novel cell death modality bridging pyroptosis, apoptosis, and necroptosis, PANoptosis offers fresh insights into the complexity of cell death and provides innovative strategies for CVD treatment. This review summarizes current evidence linking PANoptosis to various CVDs, including myocardial ischemia/reperfusion injury, myocardial infarction, heart failure, arrhythmogenic cardiomyopathy, sepsis-induced cardiomyopathy, cardiotoxic injury, atherosclerosis, abdominal aortic aneurysm, thoracic aortic aneurysm and dissection, and vascular toxic injury, thereby providing critical clinical insights into CVD pathophysiology. However, the current understanding of PANoptosis in CVDs remains incomplete. First, while PANoptosis in cardiomyocytes and vascular smooth muscle cells has been implicated in CVD pathogenesis, its role in other cell types—such as vascular endothelial cells and immune cells (e.g., macrophages)—warrants further investigation. Second, although pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) are known to activate the PANoptosome in infectious diseases, the stimuli driving PANoptosis in CVDs remain poorly defined. Additionally, methodological challenges persist in identifying PANoptosome assembly in CVDs and in establishing reliable PANoptosis models. Beyond the diseases discussed, PANoptosis may also play a role in viral myocarditis and diabetic cardiomyopathy, necessitating further exploration. In conclusion, elucidating the role of PANoptosis in CVDs opens new avenues for drug development. Targeting this pathway could yield transformative therapies, addressing unmet clinical needs in cardiovascular medicine.

ObjectiveTo investigate the mechanism of kidney-tonifying and liver-regulating cyclical therapy and its formula in regulating endometrial receptivity during the "implantation window" in rats with polycystic ovary syndrome (PCOS). MethodsSix rats were randomly selected from 36 SPF SD female rats as the normal group, and the remaining rats were administered letrozole to induce a PCOS model. By using a random number method, the rats were divided into the following groups: normal group, model group, Xiaoyaosan group (11.97 g·kg-1), Sanzi Yangmo decoction group (28.35 g·kg-1), cyclical therapy group (11.97/28.35 g·kg-1), and aspirin group (8 × 10-3 mg·kg-1). After 12 days of continuous administration by gavage (equivalent to three estrous cycles), female and male rats were co-housed. On the fifth day of pregnancy, the number of blastocyst implantation in each group was counted. Hematoxylin-eosin (HE) staining was used to observe the pathological morphology of rat endometrial tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of estradiol (E2) and progesterone (P) in rat serum. Western blot was used to detect the protein expression of vascular endothelial growth factor (VEGF), progesterone receptor (PR), estrogen receptor (ER), androgen receptor (AR), and integrin(ITG) αvβ3 in rat endometrial blood vessels. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of miR-140-5 P, VEGF, vascular endothelial growth factor receptor 2 (VEGFR2), PR, ER, AR, and ITGαvβ3 in rat endometrium. ResultsCompared with normal group, the estrous cycle of the rats in model group continued to be in the estrus interval and the estrous cycle lost regular changes. The endometrium was significantly thinner, the number of uterine glands and blood vessels were significantly reduced (P<0.01), and the pregnancy rate was significantly reduced. Compared with the model group, each drug group restored the regular estrous cycle to varying degrees, and the endometrial thickness and the number of blood vessels were significantly improved (P<0.01). The pregnancy rate of each drug group increased, and the effect of the cycle therapy group could reach the normal level. The results of molecular biology experiments showed that compared with the normal group, the levels of serum E2 and P in the model group were significantly decreased (P<0.01), the expression of VEGF, ER, PR and ITGαvβ3 protein was significantly decreased (P<0.05,P<0.01), the expression of AR protein was significantly increased (P<0.01), the expression of miR-140-5P and AR mRNA was significantly increased (P<0.01), and the expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA was significantly decreased (P<0.01). Compared with model group, the serum E2 level in the Xiaoyaosan group was significantly increased (P<0.01).The levels of E2 and P in serum of rats in Sanzi Yangmo decoction group, cycle therapy group and aspirin group were significantly increased (P<0.01). The expression of AR protein in each drug group was significantly decreased (P<0.01). The expression of VEGF and ITGαvβ3 protein in Xiaoyaosan group was significantly increased (P<0.01). The expression of VEGF, ER and PR protein in Sanzi Yangmo decoction group was increased to varying degrees (P<0.05,P<0.01). The expression of VEGF, PR, ER and ITGαvβ3 protein in the cycle therapy group and the aspirin group increased to varying degrees (P<0.05,P<0.01). The expression of miR-140-5P and AR mRNA in each drug group was significantly decreased (P<0.01). The expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA in each drug group increased to varying degrees (P<0.05,P<0.01). Compared with Xiaoyaosan group and Sanzi Yangmo decoction group, the expression of miR-140-5P, VEGFR2, ER, PR, AR and ITGαvβ3 mRNA in the cycle therapy group were significantly different (P<0.05,P<0.01). ConclusionThe kidney-tonifying and liver-regulating cyclical therapy may reduce the activity of miR-140-5P, target the upregulation of VEGF expression, mediate angiogenesis, and promote endometrial angiogenesis, thereby playing a synergistic role in improving endometrial receptivity in PCOS-induced infertility. Its efficacy in increasing pregnancy rates surpasses that of Xiaoyaosan or Sanzi Yangmo decoction used alone.

Purpose:
The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations.
Methods:
This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits.
Results:
Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01).
Conclusion
Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.
