This study aimed to investigate the effect of atractylenolide I (Atr-I) on myocardial mitochondrial function in mice with dilated cardiomyopathy (DCM) by regulating the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway. Sixty SPF-grade male cTnT R141W transgenic DCM mice were randomly divided into the DCM group, Atr-I low-dose group (60 mg/kg), Atr-I high-dose group (240 mg/kg), captopril group (0.01 g/kg), and Atr-I high-dose+cGAS/STING pathway activator 5,6-dimethylxanthenone-4-acetic acid (DMXAA) group, with 12 mice in each group. Additionally, 12 male C57BL/6J mice were used as the control group. All mice were administered via oral gavage once daily for 8 weeks. Cardiac function was assessed using the Vevo 770 ultrasound system; myocardial pathology was examined via HE staining; mitochondrial ultrastructure in cardiomyocytes was observed using transmission electron microscopy; the proportion of cardiomyocytes without reduced mitochondrial membrane potential was detected using JC-1 staining; reactive oxygen species (ROS) content in myocardial tissue was measured using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) staining; adenosine triphosphate (ATP) content in myocardial tissue was determined using a commercial kit; and Western blot was performed to detect the protein expression levels of mitofusin-2 (MFN2), dynamin-related protein 1 (DRP1), cGAS, STING, interferon-β (IFN-β), CXC chemokine ligand 10 (CXCL10), and interleukin-6 (IL-6) in myocardial tissue. The aim was to observe the effect of Atr-I on myocardial mitochondrial function in DCM mice. The results showed that low- and high-dose Atr-I (60 mg/kg, 240 mg/kg) intervention improved cardiac function, alleviated cardiomyocyte hypertrophy and disordered muscle fiber arrangement, ameliorated mitochondrial ultrastructure in cardiomyocytes, reduced ROS content and the protein expression levels of DRP1, cGAS, STING, IFN-β, CXCL10, and IL-6 in myocardial tissue, and increased the proportion of cardiomyocytes without reduced mitochondrial membrane potential, as well as ATP content and MFN2 protein expression in myocardial tissue. However, DMXAA attenuated the beneficial effects of high-dose Atr-I on myocardial mitochondrial function in DCM mice. In conclusion, Atr-I may improve myocardial mitochondrial function in DCM mice by inhibiting the cGAS/STING pathway.

Functional dyspepsia （FD） is a prioritized disease category where traditional Chinese medicine （TCM） demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents， with digestive enzymes， probiotics and antidepressants serving as adjuvant medication， yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines， as well as external TCM therapies such as acupuncture and moxibustion， acupoint application， hot medicinal compress therapy， rubbing with ointment， medicinal iontophoresis， auricular acupoint therapy and tui na （Chinese medical massage）. The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD， mainly focusing on restoring gastrointestinal motility， regulating the levels of brain-gut peptides， modulating intestinal microecology， and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM， and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment， so as to provide personalized and comprehensive treatment regimens for FD patients.

Objective: To understand the current status of short video addiction among vocational nursing students in higher vocational colleges (hereinafter referred to as "nursing students") and its related factors, so as to provide a reference for formulating online education programs in colleges. Methods: From March to May 2025, a stratified random sample of 2 223 nursing students from four vocational colleges in Henan Province was selected. Short Video Addiction Scale for College Students, Short form Egna Minnen av Barndoms Uppfostran for Chinese, Peer Rejection Scale, and University of California at Los Angels Loneliness Scale were used for investigation. Chi square test and multivariate Logistic regression analysis were used to explore the related factors of short video addiction among nursing students. Results: The detection rate of short video addiction of higher vocational nursing students was 26.95%, and the scores for avoidance, loss of control, inefficiency and withdrawal were (8.05±2.97) (10.24±3.09) (4.99±1.88) and (11.97±4.10), respectively. Multivariate Logistic regression analysis showed that sophomore year 2 ( OR=1.83, 95%CI =1.39-2.40), higher maternal education level (secondary school/vocational college: OR =1.34, 95% CI =1.06-1.68; college/undergraduate: OR =1.38, 95% CI =1.05-1.82), paternal overprotection ( OR=1.59, 95%CI =1.27-2.00), high peer rejection ( OR=1.40, 95%CI =1.19-1.66), and strong loneliness ( OR=1.57, 95%CI =1.07-2.28) were associated with a higher risk of short video addiction among nursing students (all P <0.05). Paternal affectionate and warm rearing style ( OR=0.82, 95%CI = 0.71- 0.95) was associated with a lower risk of short video addiction ( P <0.05). Conclusions The detection rate of short video addiction among nursing students is relatively high. Short video addiction is related to the nursing students grade, maternal education level, paternal overprotection and affectionate rearing style, peer rejection, and loneliness.

Background Diarrhea disease is a common intestinal infectious disease, and its incidence is affected by meteorological conditions. A better understanding of its epidemiological patterns and influencing factors, together with the construction of reliable prediction models, is of great significance for precise public health prevention and control. Objective To clarify the epidemic characteristics of adult diarrhea disease in Shanghai, analyze the associations of meteorological factors and a web search index with adult diarrhea disease, and develop and compare forecasting models to support precise regional prevention and control. Methods Weekly surveillance data of adult diarrhea disease cases from the Shanghai Comprehensive Surveillance Information System for Diarrhea Diseases, together with concurrent meteorological observation data and web search index (Baidu index) data from 2014 to 2019, were collected. A distributed lag non-linear model (DLNM) was adopted to analyze the associations of multiple meteorological factors and the web search index with the number of diarrhea disease cases. By integrating meteorological factors and web search index data, three types of forecasting models were developed, including autoregressive integrated moving average (ARIMA), Random Forest, and extreme gradient boosting (Xgboost), and their predictive performances were evaluated. Results Adult diarrhea disease in Shanghai exhibited seasonal variation, with an major incidence peak in summer and winter peaks in some years. The number of cases declined annually after 2015. Mean temperature was significantly associated with the risk of diarrhea disease, and both low and high temperature exposures were associated with increased risks. The highest risk was observed at 32.8°C (RR=2.04, 95%CI: 1.62, 2.55), while the strongest effect of low temperature was observed at 0.9 °C (RR=1.53, 95%CI: 1.25, 1.88). When relative humidity exceeded 69%, the risk of diarrhea disease increased with relative humidity, reaching a peak at 81% (RR=1.20, 95%CI: 1.07, 1.35). When weekly cumulative precipitation exceeded 16 mm, the risk also increased with increasing precipitation, reaching a maximum at 105 mm (RR=1.23, 95%CI: 1.07, 1.42). The web search index was positively associated with the risk of diarrhea disease. Model prediction indicated that both the Random Forest model and the Xgboost model adequately captured the overall trend in diarrhea disease cases, with R² values generally exceeding 0.7. Notably, the Xgboost model demonstrated greater accuracy in capturing peak intensities. Conclusion Meteorological factors are associated with adult diarrhea disease in Shanghai. The web search index may serve as an auxiliary indicator for diarrhea forecasting. Machine learning models, with advantages in integrating multisource data, may provide effective predictive tools for the prevention and control of diarrhea disease.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective To explore the value of the time to positivity(TTP)combined with inflammatory indicators for identifying coagulase-negative Staphylococcus(CoNS)bloodstream infection and contamination in tumor patients.Methods A retrospective analysis was performed on totally 368 tumor patients with blood culture-positive admitted to the hospital from September 2022 to April 2023,and 47 patients with blood cul-ture-positive CoNS and complete clinical data were selected as research objects.The patients were divided into CoNS infection group(24 cases)and CoNS contamination group(23 cases)according to the diagnostic criteria of bloodstream infection and in combination with the clinical manifestations and laboratory examination re-sults.In addition,5 tumor patients with blood culture Staphylococcus aureus positive admitted to the hospital during the same period were selected as the control group.The TTP,percentage of immature granulocytes(IG%),absolute value of immature granulocytes(IG#),white blood cell count(WBC),neutrophil percent-age(NE%),neutrophil-to-lymphocyte ratio(NLR),C-reactive protein(CRP)and procalcitonin(PCT)levels in all groups were compared.Results Among the 47 patient isolates of CoNS from blood cultures,Staphylo-coccus hominis was the most common,accounting for 42.55%.There were significant differences in TTP,NE%,NLR and CRP levels between CoNS infection group,CoNS contamination group and control group(P<0.05).The TTP in CoNS infection group was shorter than that in CoNS contamination group,and the levels of NE%,NLR,CRP and PCT were higher than those in CoNS contamination group,with statistical sig-nificance(P<0.05).TTP combined with NLR,CRP and PCT had the largest area under the curve,which was 0.971(P<0.000 1),with a sensitivity of 91.67%,specificity of 95.65%,likelihood ratio of 21.08,positive predictive value of 91.67%,negative predictive value of 95.65%,and an accuracy of 93.62%.Conclusion TTP combined with NLR,CRP and PCT have important clinical value in the differential diagnosis of CoNS blood-stream infection and contamination in tumor patients.

Objective To investigate the post-intervention experiences in elderly stroke patients who received the group-based acceptance and commitment therapy(ACT)and to provide a reference to improve the group-based ACT intervention strategies for the patients.Methods With the descriptive phenomenological research,the semi-structured in-depth interviews were conducted with 15 elderly stroke patients who had received the group-based ACT intervention for 6 months in a Tier-IIIA hospital in Hunan Province between May and July 2023.The data acquired from the interviews were analysed using the Colaizzi method.Results The experiences in elderly stroke patients with the group-based ACT intervention were categorised into three main themes and ten sub-themes:(1)The impact of intervention on the psychology and spirit(change cognition and accept oneself;enhance awareness and reflect on oneself;clarify values and adapt to oneself;disengage from suffering and achieve dissociation;understand suffering and discover a sense of meaning in life);(2)Behavioural changes brought by the intervention(change approaches to improve health;engage in rehabilitation exercises and build confidence;enhance social interactions and integrate into life);(3)Suggestions for the intervention program(tailor to the physiological characteristics of the elderly;adapt to the psychological characteristics of the elderly).Conclusion The group-based ACT intervention has a beneficial effect on the psychological,spiritual and behavioural changes in the elderly stroke patients.The intervention programs should be improved according to the physical and mental characteristics therefore to improve the mental health of elderly stroke patients.

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder in women of childbearing age, which can cause metabolic disorders, cardiovascular disease, ovarian cancer, uterine cancer and other complications, seriously endangering the health of the body. China has become one of the countries with the fastest increasing prevalence of PCOS, but its complex pathogenesis leads to highly heterogeneous clinical manifestations, making it difficult to completely cure. Therefore, clarifying the potential pathogenesis of PCOS is of great significance for early clinical screening, diagnosis, treatment, and prognosis. Recent studies have shown that long noncoding RNA (lncRNA) plays a dual role in the pathogenesis of PCOS and is a potential novel biomarker and intervention target. The characteristics of multi-component, multi-target, and multi-pathway action in Traditional Chinese Medicine (TCM) are consistent with the biological properties of lncRNA, which have diverse types, dual roles, and diverse locations. However, research on lncRNA mediated PCOS and how TCM can improve PCOS by regulating lncRNA is relatively scattered, which is not conducive to the recognition of its clinical value. Therefore, this article provides a systematic review of the dual regulatory mechanism, clinical value, and TCM intervention research of lncRNA in the occurrence and development of PCOS, aiming to clarify how lncRNA affects the occurrence and development of PCOS and potential treatment strategies, in order to provide new ideas for the clinical prevention and treatment of PCOS.

Objective:To investigate the impact of different luteal phase support protocols on pregnancy outcomes in patients aged ≤35 years undergoing modified natural cycle frozen-thawed embryo transfer (mNC-FET).Methods:A retrospective cohort study was conducted to analyze 2 086 cycles of patients aged ≤35 years who received mNC-FET cycles in Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020. The cycles were divided into three groups based on luteal phase support protocols used. The patients received a combination of progesterone soft capsule and dydrogesterone in the group A (446 cycles), the patients received dydrogesterone in the group B (439 cycles), and the patients received a combination of progesterone vaginal sustained-release gel and dydrogesterone in the group C (1 201 cycles). The pregnancy and perinatal outcomes were compared between groups A and B, groups C and B after matching the baseline data in a ratio of 1∶1 using the propensity score matching (PSM). The effect of different luteal phase support on live birth rate was analyzed after adjusting for confounding factors affected by univariate and multivariate generalized estimating equation (GEE).Results:After PSM, there were no significant differences between groups A and B, groups C and B in human chorionic gonadotropin positive rate, clinical pregnancy rate, ectopic pregnancy rate, live birth rate in transplant cycle, incidence of low weight, macrosomia, premature delivery rate, pregnancy complication rate and incidence of birth defects (all P>0.05). GEE analysis showed that three different luteal phase support regimens were not associated with live birth rate. Conclusion:In the mNC-FET cycle, patients aged ≤35 years who chose dydrogesterone alone as luteal phase support drug, had no difference in live birth rate and perinatal outcome between progesterone soft capsules or progesterone vaginal sustained-release gel combined with dydrogesterone, but the outcome still needs to be confirmed by large sample prospective studies.

Objective:To explore the developmental trajectory and influencing factors of kinesiophobia in patients undergoing percutaneous coronary intervention (PCI) .Methods:By convenient sampling, totally 217 patients undergoing PCI who enrolled from two tertiary hospitals in Guangdong Province from March 2022 to July 2023. The demographic data of the patients was collected , and kinesiophobia was measured using the Tampa scale for kinesiophobia heart(TSK-SV-Heart) at one day pre-discharge, 2 weeks, 1 month, and 4 months post-discharge. Data analysis was conducted using SPSS 25.0 and Mplus 8.7 softwares. Growth mixture modelling, chi-square test, and polynomial Logistic regression were used for data processing and analysis.Results:Three different kinesiophobia trajectory classes were identified in patients within 4 months after PCI: sustained high level of kinesiophobia group (C1 group, 22.6%(49/217)), moderate level of kinesiophobia with a rapid decrease group (C2 group, 47.4%(103/217)), and rapid decrease of kinesiophobia followed an increase group (C3 group, 30.0%(65/217)). Polynomial Logistic regression results showed that, females ( B=1.136, OR=3.113, 95% CI=1.155-8.389) , patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=1.135, OR=3.112, 95% CI=1.380-7.017) were more likely to develop into the C1 compared with the C2 group. Compared with the C3 group, patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=3.322, OR=27.712, 95% CI=5.251-146.244), and patients with coronary heart disease(CHD) more than two years ( B=3.855, OR=47.250, 95% CI=2.146-1 040.535)were more likely to develop into the C1 group. Compared with the C3 group, patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=-2.187, OR=0.112, 95% CI=0.022-0.565), patients with three or more comorbidities ( B=-2.711, OR=0.066, 95% CI=0.008-0.528), and patients with CHD more than two years ( B=-2.376, OR=0.093, 95% CI=0.011-0.783) were more likely to develop into the C2 group. Conclusion:Kinesiophobia level in patients undergoing PCI presents a curvilinear decrease within 4 months after PCI.Different kinesiophobia trajectory classes can be observed. Sex, NYHA/Killip class, course of CHD, and comorbidity affect the development trajectory of different subgroups.
