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）.

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.

Objective:To evaluate the efficacy and safety of treatments in phase Ⅰ oncology clinical trials in patients with advanced non-small-cell lung cancer(NSCLC).Methods:We retrospectively analyzed the clinical data of 65 patients with advanced NSCLC who received phase Ⅰ antitumor trial drugs at the Clinical Trial Research Center of The First Affiliated Hospital of Bengbu Medical University from January 2020 to December 2023.The efficacy and occurrence of serious adverse events(SAEs)were analyzed.Results:The objective response rate(ORR)and disease control rate(DCR)were 9.2%and 61.4%,respectively,whereas the median progression-free survival(PFS)and overall survival(OS)were 2.9 and 15.1 months,respectively.Previously receiving second-line or more lines of treatment and SAE occurrence were independent risk factors for a shorter PFS(P<0.05).A history of smoking and previous second-line or more lines of treatment were inde-pendent risk factors for a shorter OS(P<0.05).The SAE incidence was 15.4%,and no treatment-related deaths occurred.Conclusions:Treat-ments in phase Ⅰ oncology clinical trials are beneficial for patients with advanced NSCLC.Patients with a higher number of previous treat-ment lines and those who experienced SAEs during the trial had a shorter PFS,whereas patients with no smoking history and fewer previous treatment lines had a longer overall survival.The overall safety of the treatments was acceptable.

Objective To observe the clinical efficacy of electroacupuncture of bilateral Yifeng(SJ17)points penetrating Lianquan(RN23)points combined with electromyographic biofeedback therapy(shortened as EMG biofeedback)in the treatment of post-stroke dysphagia.Methods A total of 94 cases of patients admitted to the wards and outpatient clinics of Handan Mingren Hospital with a definitive diagnosis of post-stroke dysphagia from April 2022 to May 2023 were selected for the study.The patients were randomly divided into observation group and control group according to the random number table method,with 47 cases in each group.Both groups of patients were given basic treatment,the control group was treated with EMG biofeedback,and the observation group was treated with electroacupuncture of bilateral Yifeng points penetrating Lianquan points on the basis of the treatment of the control group.The course of treatment covered four consecutive weeks.After one month of treatment,the clinical efficacy of the two groups was evaluated,and the changes in traditional Chinese medicine(TCM)syndrome scores and Kubota Water Swallowing Test scores,Standardized Swallowing Assessment(SSA)scores,Functional Oral Intake Scale(FOIS)scores,and Swallowing-Quality of Life(SWAL-QOL)scores before and after treatment were observed in the patients of the two groups.The changes of tongue pressure before and after treatment were compared between the two groups.The safety and the incidence of adverse reactions in the two groups were evaluated.Results(1)The total effective rate was 95.74%(45/47)in the observation group and 76.60%(36/47)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(2)After treatment,the TCM syndrome scores and Kubota Water Swallowing Test scores of the patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(3)After treatment,SSA and FOIS scores of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(4)After treatment,the peak tongue pressure,mean tongue pressure,duration of tongue pressure of the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(5)After treatment,the quality of life scores of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(6)No obvious adverse reactions occurred during the treatment of the two groups of patients,the difference in the incidence of adverse reactions between the two groups of patients being not statistically significant(P>0.05).Conclusion Electroacupuncture of bilateral Yifeng points penetrating Lianquan points combined with EMG biofeedback in the treatment of post-stroke dysphagia exerts certain efficacy,which can improve the swallowing function and tongue muscle strength,reduce TCM syndrome scores,and enhance patients'quality of life.

Purpose To investigate the clinicopathological features and cytogenetic characteristics in the fumarate hydratase(FH)-deficient uterine smooth muscle tumors.Methods A total of 334 paraffin-embedded specimen of be-nign,borderline,and malignant uterine smooth muscle tumors were collected.FH-deficient uterine smooth muscle tumors were screened using the immunohistochemical detection with FH and S-(2-succino)-cysteine(2SC)antibodies.A retrospective analysis of the clinicopathological features and FH mutations was conducted.Results Compared with the 310 non-FH-deficient uterine leiomyomas(non-FH-dUL),14 cases(93.3％)out of the 15 FH-dUL presented with staghorn blood vessels(x2=52.86,P＜0.000 1),8 cases(53.3％)exhibited pulmonary edema-like stroma(x2=26.41,P＜0.000 1),8 cases(53.3％)had cytoplasmic eosinophilic globules(x2=41.85,P＜0.000 1),5 cases(33.3％)showed multifocal bizarre nuclei(x2=72.54,P＜0.000 1),5 cases(33.3％)had large eosino-philic nucleoli with viral inclusion-like halos(x2=38.85,P＜0.000 1),and 5 cases(33.3％)demonstrated a sig-nificant increase in cell density(x2=8.782,P=0.003).The above morphological features were also observed in a case of FH-d uSTUMP and FH-d uLMS.Among the 14 cases with follow-up,except for one death in the FH-d uLMS,none reported the renal cell carcinoma and cutaneous leiomyoma.FH mutations were identified in 11 cases and the hotspot mutations were found in exon 1,2,4,5,6 and 7.Among these variations,c.125C＞T,c.151C＞T and c.704A＞C were found to be the hotspot gene variations.Furthemore,7 gene variations(c.197A＞G,c.426G＞T,c.505C＞T,c.704A＞C,c.812A＞C,c.847T＞C,c.1006A＞G)were not included in COSMIC and ClinVar database and were supposed to be novel.Conclusion The combination of FH/2SC immunohistochemical detection and FH exon mutation analysis are reliable tools for the early identification of FH-deficient uterine smooth muscle tumors or hereditary leiomyomatosis and renal cell carcinoma(HLRCC)syndrome.

Objective:To introduce the clinical application of "page-turning" superior pancreatic lymph node dissection in laparoscopic D2 radical gastrectomy for gastric cancer.Methods:Patients who were confirmed to have adenocarcinoma by preoperative gastroscopy and pathological biopsy, with tumor staging evaluated by imaging as cT1~4aN0~3M0, without neoadjuvant therapy, and without absolute surgical contraindications, underwent laparoscopic radical gastrectomy for gastric cancer with "page-turning" superior pancreatic lymph node dissection. The "page-turning" superior pancreatic lymph node dissection was performed in four steps: (1) Expose the posterior gastric mesentery and dissect No.11p lymph nodes; (2) Expose the left gastric mesentery and dissect No.7, No.8a and No.9 lymph nodes; (3) Expose the right gastric mesentery and dissect No.5 lymph nodes; (4) Expose the left edge of the portal vein and dissect No.12a lymph nodes.Results:From April 2018 to October 2024, 112 patients with gastric cancer underwent laparoscopic D2 radical gastrectomy with "page-turning" superior pancreatic lymph node dissection, including 21 cases in the First Affiliated Hospital of Guangzhou University of Chinese Medicine, 78 cases in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and 13 cases in the Department of Gastrointestinal Surgery, Jilin Provincial People's Hospital. The TNM staging of all patients was as follows: 31 cases in stage Ⅰ, 24 cases in stage Ⅱ, and 57 cases in stage Ⅲ; 62 cases of differentiated adenocarcinoma and 50 cases of undifferentiated adenocarcinoma; the median length of tumors was 3.8 cm. All patients successfully completed the operation without conversion to open surgery, no intraoperative massive hemorrhage or postoperative death. The median total number of lymph nodes dissected in all patients was 32, and the median number of positive lymph nodes was 4.5. The overall postoperative complication rate was 5.4% (6/112), all of which were Clavien-Dindo grade Ⅱ, including pulmonary infection, pleural effusion, and incisional infection, all cured by symptomatic treatment. The median follow-up was 41.8 (2-78) months, with 7 cases lost to follow-up. During the follow-up period, 27 cases (25.7%) had tumor recurrence and 16 cases (15.2%) died.Conclusions:The "page-turning" superior pancreatic lymph node dissection technique is safe and feasible in laparoscopic radical gastrectomy for gastric cancer.

Subclinical ptosis is a common congenital abnormality of bilateral upper eyelid development; the clinical manifestations are upper eyelid skin covering the upper corneal margin of more than 2 mm, upper eyelid bloat, narrow lid fissure, often accompanied by epicanthus and eyebrow elevation when the eyes are opened. Patients often present with a single eyelid, which can be easily missed and misdiagnosed. The cause of subclinical ptosis is an increase in the afterload of the levator muscle during contraction due to a variety of reasons, such as gravitational, volumetric, and tensile loads; the clinical manifestations and the normalisation of the levator muscle strength are the main basis for diagnosis and identification of true ptosis. Depending on the type of afterload, different surgical treatments are available, such as blepharoplasty, orbicularis oculi myotomy, upper eyelid tissue reduction, fibrous mesh band release, anterior displacement of the levator complex, and shortening of the levator complex.

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.
