Objective: To investigate the status of condom use and its influencing factors among men who have sex with men (MSM), so as to provide a basis for improving condom utilization rates and AIDS prevention and control in this population. Methods: From May to October 2024, a snowball sampling method was employed to recruit MSM in Songjiang District, Shanghai Municipality. Self-administered questionnaires were used to collect data on demographic characteristics, AIDS-related knowledge, sexual behaviors, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), and condom use in the past six months. Multivariable logistic regression model was used to analyze the influencing factors for consistent condom use. Results: A total of 921 MSM were surveyed, with a median age of 29.00 (interquartile range, 9.00) years. Among them, 697 (75.68%) were aware of AIDS-related knowledge, 826 (89.69%) expressed willingness to use PrEP, and 835 (90.66%) were willing to use PEP. Additionally, 787 (85.45%) MSM reported their age at first homosexual intercourse as ≥18 years, while 519 (56.35%) reported consistent condom use in the past six months. Multivariable logistic regression analysis revealed that MSM who were aware of AIDS-related knowledge (OR=0.582, 95% CI: 0.423-0.801), willing to use PrEP (OR =0.611, 95% CI: 0.385-0.969), and whose age at first homosexual intercourse was <18 years (OR=0.480, 95% CI: 0.330-0.700) were less likely to consistent use condoms. Conclusion The proportion of consistent condom use among the MSM remains relatively low, which is primarily associated with AIDS-related knowledge, willingness to use PrEP, and the age at first homosexual intercourse.

Objective To explore the application value of computed tomography (CT) three-dimensional reconstruction in total knee arthroplasty (TKA). Methods A total of 102 patients who underwent TKA in our hospital between April 2022 and April 2025 were enrolled and divided using a random number table into a traditional group (51 cases, routine preoperative evaluation) and a study group (51 cases, CT three-dimensional reconstruction-assisted surgery). The therapeutic efficacy at 3 months postoperatively and perioperative indicators were compared between the two groups. The hip-knee-ankle (HKA) angle was measured preoperatively and at 3 months postoperatively. The Hospital for Special Surgery (HSS) knee score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were recorded preoperatively and at 3 and 6 months postoperatively. Complications were documented. Results The excellent/good rate in the study group (92.16%) was higher than that in the traditional group (74.51%) (P<0.05). The operation time, intraoperative blood loss, postoperative drainage volume, and hospital stay in the study group were (69.52 ± 7.11) min, (102.69 ± 8.54) mL, (167.33 ± 12.35) mL, and (10.93 ± 2.37) days, respectively, which were shorter than those in the traditional group [(78.45 ± 5.98) min, (108.36 ± 10.02) mL, (175.96 ± 14.93) mL, and (12.04 ± 1.95) days] (P<0.05). At 3 months postoperatively, the HKA angle was 178.02° ± 1.05° in the study group and 177.45° ± 1.34° in the traditional group, both were significantly improved compared with those before operation, with the study group showing better improvement (P<0.05). The HSS knee and WOMAC scores in both groups at 3 and 6 months postoperatively were improved compared with preoperative scores (P<0.05). At 3 and 6 months postoperatively, the study group showed higher HSS knee score and lower WOMAC score than the traditional group (P<0.05). The incidence of complications in the study group (3.92%) was lower than that in the traditional group (17.65%) (P<0.05). Conclusion TKA guided by CT three-dimensional reconstruction improved the excellent/good rate, optimized HKA angle and knee function, shortened operation time and hospital stay, reduced intraoperative blood loss and postoperative drainage volume, and decreased the incidence of complications.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

AIM:To observe the therapeutic efficacy of 25G+minimally invasive vitrectomy for retinal arterial macroaneurysm.METHODS:Totally 40 patients(40 eyes)who admitted to Jinan Mingshui Eye Hospital from January 2021 to May 2024 and with vitreous hemorrhage or dense premacular hemorrhage in the macular area caused by retinal arterial macroaneurysm, underwent 25G+minimally invasive vitrectomy. Preoperative and postoperative best-corrected visual acuity(BCVA), complications, and special cases were analyzed.RESULTS: The general patient data aligned with previous literature reports. The postoperative BCVA was significantly improved(t=9.72, P<0.01), and no significant serious surgical complications were observed. Notably, intraoperative findings revealed secondary macular holes in 3 eyes, resulting in poor visual prognosis.CONCLUSION: For vitreous hemorrhage or dense premacular hemorrhage caused by retinal arterial macroaneurysm, 25G+ minimally invasive vitrectomy is a safe and effective treatment. Visual prognosis was excluded for secondary macular holes.

OBJECTIVE: To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension. METHODS: This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups. RESULTS: A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period. CONCLUSIONS Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVE: To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI). METHODS: From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales. RESULTS: Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001). CONCLUSIONS Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

AIM: To investigate the research status and hotspots in the field of ocular trauma over the past two decades using bibliometric software CiteSpace and VOSviewer.METHODS: A bibliometric study. Relevant literature on ocular trauma published in the past 20 a was retrieved from the CNKI database and Web of Science Core Collection in June 2025. EndNote X9 was used for literature management and verification. Microsoft Office Excel 2019 was employed for data management and statistics, with graphical representations created for frequency data. CiteSpace and VOSviewer were utilized to construct and analyze visual maps of authors, institutions, countries/regions, journals, and keywords.RESULTS: A total of 3 437 valid articles were included(911 in Chinese, 2 526 in English). English publications grew at an average annual rate of 12.7%(peak: 289 articles in 2021), while Chinese articles decreased from 31.2% in 2005(peak: 149 articles)to 6.3% in 2024. Chinese scholars showed an early surge in output but a subsequent declining trend, necessitating enhanced sustained research investment and translational outcomes. The United States(682 articles), China(272 articles), and India(206 articles)formed a core collaborative triangle, with a transnational collaboration rate of 68.2%. Six author clusters(e.g., Yan Hua/Zhang Maonian, et al.)demonstrated strong intra-group collaboration but minimal inter-group cooperation. Analysis of high-frequency keywords and burst terms revealed six global research hotspots: 1)ocular trauma score and minimally invasive vitrectomy; 2)optical coherence tomography(OCT)/ultrasound biomicroscopy(UBM)-guided diagnosis and management of intraocular foreign bodies; 3)amniotic membrane transplantation for chemical injury repair; 4)multimodal assessment of corneal perforation injuries; 5)inflammatory indicators for diagnosing endophthalmitis as a traumatic complication; 6)family-based interventions for preventing and controlling pediatric ocular trauma. Trends indicate a shift in research focus from emergency care toward artificial substitutes and full-cycle nursing rehabilitation.CONCLUSION: Differences in research outputs between China and other countries reflect imbalances in prevention policies and medical resource allocation. China should strengthen sustained investment and overcome collaboration barriers to jointly advance ocular trauma research toward full-cycle precision management.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.
