Objective: To explore the relationship of social anxiety and emotion regulation strategy with short video addiction among college students, so as to provide reference for alleviating social anxiety, improving the level of emotion regulation and preventing short video addiction. Methods: From May to June 2024, 2 172 college students from a university in Guangzhou were selected by multistage random cluster sampling method. The Interaction Anxiousness Scale, Emotion Regulation Questionnaire and Short Video Addiction Scale were used as the measurement tools. The potential profile was used to analyze the potential categories of social anxiety and emotion regulation strategy. The Chi square test was used to analyze the characteristics of the distribution of potential profile categories of college students with different demographic characteristics. Multiple linear regression analysis was used to analyze the relationship between social anxiety, emotion regulation strategy and short video addiction. Results: The potential categories of social anxiety and emotion regulation strategy in college students were divided into adaptive regulation type (784 cases, 36.10 %), low anxiety-expression type (623 cases, 28.68%), inhibition-anxiety type (478 cases, 22.01%), high anxiety-disorder type (287 cases, 13.21%). There were statistically significant differences in the distribution of various potential categories of social anxiety and emotion regulation strategy among cadres of different gender, family residence, class cadres or not ( χ 2=42.55, 17.86 , 39.05, all P <0.01). Multiple linear regression analysis showed that after controlling the confounding factors such as demographic variables, the potential categories of social anxiety and emotion regulation strategy of college students (low anxiety-expression type, inhibition-anxiety type, high anxiety-disorder type) were the important related factors of short video addiction ( β =0.15,0.25,0.35, all P <0.05). Conclusions Social anxiety and emotion regulation strategy of college students exhibit distinct categorical characteristics, and its varying latent categories are associated with short video addiction. Schools should implement targeted intervention measures for different categories of college students to promote their comprehensive mental health development.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Background Ambient air pollution is a major environmental risk factor for cardiovascular disease (CVD). However, epidemiological evidence regarding the modifying effect of a healthy lifestyle on the association between air pollution and CVD remains inconsistent. Objective To investigate the modifying effect of a healthy lifestyle on the association between exposure to air pollutants and CVD risk, to provide evidence for targeted prevention strategies. Methods Databases including PubMed, Web of Science, Embase, the Cochrane Library, CNKI, and Wanfang were systematically searched for epidemiological studies published from January 2011 to August 2025. The quality of included studies was assessed, and relevant data were extracted. A meta-analysis was performed to examine the association between air pollutant exposure and CVD outcomes, as well as the modifying effect of a healthy lifestyle. Results A total of 24 studies were included. The meta-analysis demonstrated that each 10 μg·m⁻³ increase in the concentration of ultrafine particulate matter (PM₁), fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and ozone (O₃) was associated with pooled relative risks (RRs) for CVD morbidity of 1.176 (95%CI: 1.007, 1.373), 1.167 (95%CI: 1.035, 1.315), 1.030 (95%CI: 1.012, 1.048), 1.093 (95%CI: 1.039, 1.150), 1.014 (95%CI: 0.996, 1.032), and 1.216 (95%CI: 0.901, 1.641), respectively; each 10 mg·m⁻³ increase in the concentration of carbon monoxide (CO) was associated with a pooled RR for CVD morbidity of 1.005 (95%CI: 1.005, 1.006). For CVD mortality, each 10 μg·m⁻³ increase in PM_2.5, PM₁₀, and NO₂ yielded pooled RRs of 1.188 (95%CI: 1.032, 1.367), 1.137 (95%CI: 0.953, 1.357), and 1.038 (95%CI: 1.011, 1.066), respectively; for SO₂ and O₃, where only a single study was available, RRs were 1.068 (95%CI: 1.030, 1.108) and 1.010 (95%CI: 0.996, 1.024) per 10 μg·m⁻³ increase, respectively; for CO, where also only a single study was available, the RR was 1.002 (95%CI: 1.001, 1.003) per 10 mg·m⁻³ increase. Adherence to a healthy lifestyle significantly modified the PM_2.5-associated CVD risk. Specifically, compared to healthy behaviors, unhealthy factors including smoking, low-quality diet, and physical inactivity exacerbated this risk, with relative effect sizes (RES; ratio of hazard ratios of the unhealthy group to the healthy group) of 1.016 (95%CI: 1.013, 1.020), 1.008 (95%CI: 1.003, 1.013), and 1.058 (95%CI: 1.055, 1.062), respectively. Furthermore, a combined healthy lifestyle demonstrated a superior modifying effect compared to any single lifestyle factor, which significantly attenuated the PM_2.5-associated CVD risk (P for interaction < 0.05). Conclusion Long-term exposure to ambient PM_2.5 significantly increases CVD risk. However, adherence to a combined healthy lifestyle can effectively mitigate these adverse effects, offering substantially greater cardiovascular protection than maintaining any single healthy habit.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To explore the efficacy and safety of one-hole split endoscope (OSE) minimally invasive surgery for the treatment of single-segment thoracic ossification of the ligamentum flavum (TOLF).Methods:This retrospective non-randomized controlled study included 41 patients with single-segment TOLF who underwent surgery at Qilu Hospital of Shandong University between July 2019 and July 2023. Patients were divided into two groups: the OSE group (19 cases) treated with one-hole split endoscope minimally invasive surgery and the open group (22 cases) treated with traditional laminectomy and pedicle screw fixation. There were no significant differences between the two groups on gender, age, disease duration, affected segment, presence or absence of dural ossification, and residual cross-sectional vertebral canal area on CT ( P>0.05). Additionally, perioperative surgical time, estimated blood loss (EBL), incision length, hospital stay duration, hospitalization costs and follow-up duration were compared. The Japanese Orthopaedic Association (JOA) score and Oswestry Disability Index (ODI) were compared preoperatively and at the last follow-up. Complications were also recorded. Results:All patients successfully completed the surgery with no significant differences at the last follow-up ( P>0.05). Compared with the open group, the OSE group had a significantly shorter operative time (133.1±16.8 vs. 160.5±22.6 min), lower EBL (91.2±15.0 vs. 192.5±43.8 ml), shorter incision length (2.6±0.5 vs. 7.9±1.9 cm), reduced hospital stay (3.9±0.8 vs. 5.6±0.8 days), and lower hospitalization costs (34,874.9±4,568.6 vs. 53,162.3±9,815.6 yuan) (all P<0.05). AAt the final follow-up, JOA scores (8.5±0.8 vs. 8.6±1.2) and ODI values (16.7%±2.1% vs. 17.7%±4.4%) showed no significant differences between the OSE and open groups ( P>0.05). During the perioperative period and follow-up, complications occurred in 2 patients in the OSE group (1 cerebrospinal fluid leak, 1 poor wound healing) and in 8 patients in the open group (5 cerebrospinal fluid leaks, 1 neurological deterioration, 2 poor wound healing). Conclusion:OSE minimally invasive surgery is an effective treatment for single-segment thoracic ossification of the ligamentum flavum. Compared with open surgery, it provides advantages such as minimal invasiveness and fewer complications.

STC is a kind of clinically common functional gastrointestinal disease.Its pathogenesis hasn't been completely clarified,and current diagnosis and treatment norms are certainly limited.In recent years,"Brain-Gut Axis"theory has unveiled the complex bidirectional regulation mechanism between brain and intestinal tract,rendering new perspective for the research and treatment of STC.TCM theory demonstrates that there is close connection between brain and gut,has formed abundant experience in discrimination and treatment of STC and formed unique diagnosis and treatment ideas.Based on the theory of"Brain-Gut Axis"and"excess syndrome is corresponding to Zhanyu,deficiency syndrome is corresponding to Zhengsheng"in the chapter on Yangming diseases in"Treatise on Febrile Diseases",this paper elaborates on the relationship between the"Brain-Gut Axis"and STC.Meanwhile,by combining the theory of"excess syndrome is corresponding to Zhanyu,deficiency syndrome is corresponding to Zhengsheng"with the"Brain-Gut Axis"theory,it analyzes the influence of the excess and deficiency of the Yangming meridian on the mental state as well as the regulatory mechanism of the"Brain-Gut Axis",and puts forward corresponding treatment methods according to different syndromes.By integrating the relevant provisions in"Treatise on Febrile Diseases"with the"Brain-Gut Axis"theory of modern medicine,this paper makes a preliminary exploration of the laws of differentiating and treating STC,aiming to provide a theoretical basis for promoting a more comprehensive understanding of the pathogenesis of STC and developing more effective treatment strategies.

Objective To evaluate the efficacy and safety of polyethylene glycol electrolyte powder(PEG)combined with linaclotide(Lin)for bowel preparation in elderly constipated patients before colonoscopy.Methods In this prospective,randomized controlled trial,90 elderly patients with constipation undergoing colonoscopy were recruited at our hospital from June 2022 to December 2023.Participants were randomly assigned to three groups(n=30 each):PEG-3L alone,PEG-3L+Lin,and PEG-2L+Lin.Primary outcome was Boston Bowel Preparation Scale(BBPS)score and secondary outcomes included adverse event rates,colonoscopy completion rate,withdrawal time,and polyp detection rate.Statistical analysis was performed using independent t-tests and chi-square tests.Results The PEG-3L+Lin group achieved significantly higher BBPS scores than both PEG-3L alone and PEG-2L+Lin groups did(both P<0.001).The PEG-2L+Lin group also outperformed the PEG-3L alone group in cleansing efficacy(90.0%vs.76.7%,P=0.008).The PEG-2L+Lin group demonstrated the best tolerability and lowest adverse event rate,the PEG-3L group had the longest withdrawal time(P<0.05),but the three groups showed no significant difference in polyp detection rates.Conclusion PEG combined with linaclotide significantly improves bowel cleansing in elderly constipated patients.PEG-2L+Lin regimen provides optimal balance between efficacy,safety,and tolerability,making it a preferable choice for this population.

Objective To evaluate the application of high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)in identifying high-risk features of intracranial atherosclerotic plaques,and to analyze the correlation between plaque characteristics and stroke recurrence under varying degrees of stenosis.Methods The data from 368 patients with intracranial atherosclerotic stenosis(ICAS)across two centers were retrospectively analyzed.Based on the degree of stenosis,all patients were categorized into mild-to-moderate stenosis group(luminal stenosis<70%,n=155)and severe stenosis group(luminal stenosis≥70%,n=213).HRMR-VWI images and clinical information of the patients were collected and analyzed,and the culprit plaques were quantitatively analyzed.Univariate and multivariate logistic regression analyses were employed to identify the risk factors for stroke recurrence,and the predictive performance was evaluated using the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results Higher normalized wall index(NWI)[odds ratio(OR)=1.082,95%confidence interval(CI)1.050-1.118,P<0.05]and the presence of intraplaque hemorrhage(IPH)(OR=1.843,95%CI 1.120-3.036,P<0.05)were risk factors for stroke recurrence in all patients.And these two factors were also significant in the mild-to-moderate stenosis group(NWI:OR=1.088,95%CI 1.009-1.186,P<0.05;IPH:OR=4.049,95%CI 1.227-16.065,P<0.05).A predictive model for stroke recurrence was constructed using the combination of IPH and NWI,with the best performance in the mild-to-moderate stenosis group(AUC=0.813,95%CI 0.723-0.906).Conclusion In patients with luminal stenosis<70%,the increase of NWI and the presence of IPH have been validated as significant and effective indicators for predicting stroke recurrence,demonstrating notable predictive performance.In contrast,among patients with luminal stenosis≥70%,the utility of plaque characteristics in predicting stroke recurrence is relatively lower,indicating that the correlation between plaque characteristics and stroke recurrence varies across different degrees of stenosis.

Objective:To isolate Yersinia enterocolitica phage and study its biological and genomic characteristics, and explore its application value. Methods:Phages were isolated from cecum of Apodemus chevrieri in the plague focus of wild rodent in Lijiang employing Yersinia enterocolitica (CMCC52301) as the host strain. After purification, proliferation and concentration, the morphology was observed by transmission electron microscope, and the host spectrum of the phage was determined by double-layer plate method. Phage DNA was extracted and sequenced, and the raw sequences data were assembled and visually analyzed, also performed genome functional annotation, phage classification status, phylogenetic tree, genome collinearity analysis, etc. Results:One strain of Yersinia enterocolitica phage was isolated and named vB_Yen_YN301-151, which had a head and a contractile tail. The phage only lysed Yersinia enterocolitica, and could not lyse other tested strains. And at a lysis temperature of 37 ℃, more transparent plaques were observed compared to at a lysis temperature of 21 ℃. The gene structure of this phage was double-stranded DNA, with a genome length of 51 176 bp and a GC content of 46.96%, and 95 genes were predicted to encode 15 structural morphological related proteins, 9 proteins involved in replication and metabolism, 3 DNA assembly functional proteins, 1 phage lysis related protein, and 67 hypothetical proteins. It was identified that the phage belong to the Drexlerviridae family of the Caudoviricetes class, clustered with vB_YenM_534, vB_Yen_X1, vB_YenM_281, and vB_YenM_531 in the phylogenetic tree and exhibited good collinearity with PY100, vB_YenM_ 25, and vB_Yen_X1. Conclusions:The successfully isolated vB_Yen_YN301-151 is a novel phage belonging to the Drexlerviridae family, and its gene encoded proteins are mostly hypothetical proteins. It only lyses Yersinia enterocolitica, with host specificity and has the potential to be used as diagnostic phage for screening Yersinia enterocolitica.
