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.

ObjectiveTo investigate the effect of repetitive peripheral magnetic stimulation (rPMS) combined with upper limb intelligent robotic training on muscle tension, motor function and cortical excitability in children with unilateral spastic cerebral palsy (USCP). MethodsFrom March, 2023 to December, 2024, 90 children with USCP admitted to Children's Hospital of Soochow University were selected and randomly divided into control group (n = 30), rPMS group (n = 30) and combined group (n = 30). The control group received conventional occupational therapy. The rPMS group received rPMS intervention followed by conventional occupational therapy. The combined group received rPMS followed by upper limb intelligent robot training, for four weeks. Before and after treatment, muscle tension of biceps brachii was assessed using the modified Ashworth Scale (MAS); upper limb motor function was evaluated using the Fugl-Meyer Assessment-Upper Extremity (FMA-UE) and upper limb intelligent parameters; and cortical excitability was measured using transcranial magnetic stimulation (TMS), including resting motor threshold (RMT) and motor-evoked potential (MEP) amplitude of the affected hemisphere. ResultsAfter treatment, MAS grades improved in all groups (|Z| > 3.523, P < 0.001), and the improvement in the combined group was superior to that in the control group (P < 0.05). Significant intra-group (F > 65.21, P < 0.001), inter-group (F > 17.94, P < 0.001) and interaction effects (F > 5.36, P < 0.01) were observed in FMA-UE scores, upper limb intelligent parameters and TMS parameters. Post Hoc analysis showed that the combined group demonstrated significantly greater improvements in FMA-UE scores, upper limb intelligent parameters, and TMS parameters compared with both the control and rPMS groups (all P < 0.01). Except for FMA-UE scores, the rPMS group showed significantly greater improvements than the control group in upper limb intelligent parameters (mechanical feedback, trajectory, and range of motion) and TMS parameters (RMT and MEP amplitude) (P < 0.05). ConclusionrPMS combined with upper limb intelligent robotic training can reduce upper limb muscle tension, improve motor function, and enhance cortical excitability in children with USCP.

The search period was from the establishment of the database until February 2026. Results: After screening, a total of 19 articles were included, encompassing 3 clinical decisions, 1 recommended practice, 4 guidelines, 7 expert consensuses, and 4 evidence summaries. Twenty-five pieces of best evidence were summarized across 8 aspects: multidisciplinary collaboration, influencing factors, assessment and monitoring, diagnostic differentiation, symptom management, dietary nutrition, medication guidance, and health education. Conclusion: Summarizing the relevant evidence on the management of patients with gastrointestinal graft-versus-host disease after hematopoietic stem cell transplantation can provide evidence-based support for clinical medical staff, and it is recommended to apply it in combination with clinical practice and patient wishes.

Objective To explore the utility of comprehensive geriatric assessment (CGA) in screening risk factors for osteosarcopenia (OS) among older adults (≥80 years old) and to evaluate the therapeutic efficacy of CGA-guided integrated interventions for OS. Methods A total of 420 patients aged ≥80 years, recruited from the Department of Geriatrics, General Practice of The Affiliated Jiangyin Hospital of Nantong University, and community health centers from January 2022 to October 2024, were enrolled. Participants were classified into OS (n＝139) and non-OS (n＝281) groups based on diagnostic criteria. CGA was utilized to compare differences in general characteristics, laboratory indicators, comorbidities between groups. Binary logistic regression analysis identified independent risk and protective factors. Subsequently, 40 OS patients were randomly assigned to an intervention group (n＝20) receiving integrated interventions including nutritional support, exercise training, and psychological management or a control group (n＝20, receiving routine care). Appendicular skeletal muscle mass index (ASMI), grip strength, gait speed, and bone mineral density (BMD) T-score were compared between groups after 3 months. Results The prevalence of OS in this cohort was 33.1%. Compared to the non-OS group, the OS group exhibited significant differences in age, body mass index (BMI), smoking history, comorbidity index, concomitant medication, cognitive impairment, visual and hearing impairment, sleep disorders, depression, marital status, social participation, activities of daily living, nutritional risk, total cholesterol, uric acid, and constipation (P＜0.05). Logistic regression analysis identified age and comorbidity index as significant risk factors for OS, while BMI, married status, total cholesterol, and activities of daily living (assisted and independent) served as protective factors. The intervention group demonstrated significant improvements in grip strength, gait speed, BMD T-score, and male ASMI compared to controls (P＜0.05). Conclusions CGA demonstrates clinical utility in systematically identifying risk factors for OS in the old population. Multimodal interventions guided by CGA effectively improve musculoskeletal function in elderly OS patients.

Objective:To investigate the efficacy of 3D-printed navigation guided pudendal lead implantation on nervous regula-tion of lower urinary tract symptoms(LUTS)in male patients.Methods:Twenty-eight male patients who underwent perineal nervous regulation treatment for LUTS in Gongli Hospital of Pudong New Area from October 2021 to October 2023 were randomly divided into observation group and control group.The technology assisted with 3D-printed navigation to regulate the genital nerves was used in ob-servation group.And the patients in control group were treated with regulation of the genital nerves by routine puncture.Operation time of puncture,number of surgical punctures,and stimulator debugging time compared between the two groups.The improvement of post-operative symptoms and surgical complications of patients in the observation group were recorded as well.Result:A total of 12 male LUTS patients were included in the observation group,with an average age of 36.5±6.5 years,including 7 cases of frequent micturi-tion,3 cases of perineal pain,and 2 cases of dysuria.Four patients showed no significant improvement in symptoms,including two pa-tients with pain and two cases of frequent micturition who did not undergo secondary surgery.While the other eight patients showed sig-nificant improvement in symptoms.The average time for successful puncture in control group was(21.13±4.53)minutes,which was longer than that of the 3D-printed navigation group([10.32±3.42]min)significantly(P＜0.05).The average number of punctures in the ordinary puncture group was 5.62±1.43,which was significantly higher than that in the 3 D-printed navigation group(1.5±0.56).There was no statistically significant difference in the average time for stimulator debugging between the two groups of patients.The conversion rate of the 3D-printed navigation group in the second phase was 66.7％,which was higher than that(37.5％)significantly(P＜0.05).Conclusion:3D printing navigation of pudendal nerve electrode wire implantation can improve the accuracy of electrode implantation and the conversion rate to a certain extent,which has the advantages of reducing the difficulty of surgery.

Objective To carry out quality control testing of anesthesia ventilators to ensure the reliability and safety during their clinical use.Methods Totally 88 anesthesia ventilators used in some hospital underwent quality control testing in terms of tidal volume,peak airway pressure and positive end-expiratory pressure by using a gas flow analyzer according to JJF(E)61-2020 Calibration Specification of Anesthetic Machines,which included 31 ones,36 ones,12 ones and 9 ones respectively from brand A,B,C and D.The Kruskal-Wallis test was used to analyze the variability of the measured values and errors of the performance indicators between different brands of anesthesia ventilators,the chi-square test was applied to discussing the variability of the accuracy class of the performance indicators between different brands of anesthesia ventilators,and the Pearson correlation coefficient was adopted to investigate the correlation between the years of use and the absolute values of the relative errors of the performance indicators.Results The 88 anesthesia ventilators had the overall pass rate for quality control testing being 42.05%,of which,brand B had the highest pass rate(52.78%)and brand C had the lowest pass rate(8.33%).Brand B gained advantages in tidal volume when compared with brand A,C and D,with the differences being significant(P<0.05);brand A behaved the best in peak airway pressure and positive end-expiratory pressure when compared with brand B,C and D,with the differences being significant(P<0.05).Brand A had the highest proportion(63.08%)of distinction and credit in terms of the three performance indicators.The absolute value of the relative error in tidal volume was positively correlated with the years of use at the 3 measurement points for setting values of 400,600,and 800 mL respectively(P<0.05),and there was a significant correlation between the absolute value of the relative error and the years of use at a peak airway pressure setting of 10 cmH2O(1 cmH2O=98.07 Pa)(P<0.05).Conclusion Quality control testing of anesthesia ventilators contributes to finding the risks during their application,which can be an effective tool to ensure the safety of anesthesia ventilators used in medical institutions.[Chinese Medical Equipment Journal,2025,46(9):75-80]

Objective:To understand the current status of knowledge, attitude, and practice (KAP) of nurses in palliative care under the model of palliative co-care in hospitals of different levels in Zhejiang Province, and to analyze the influencing factors.Methods:This study was a cross-sectional study. Convenience sampling was used to select 541 clinical registered nurses from 3 Class Ⅲ hospitals, 3 Class Ⅱ hospitals, and 2 ClassⅠ hospitals in Hangzhou, Huzhou, and Lishui, Zhejiang Province, from March to April 2023. A general information questionnaire and the KAP Survey Scale of Palliative Care Under the Palliative Co-care Model were used to investigate the subjects. Multiple linear regression analysis was conducted to analyze the influencing factors of nurses' KAP of palliative care under palliative co-care. A total of 541 questionnaires were distributed, and 535 valid questionnaires were recovered, with an effective response rate of 98.89%.Results:The scores of 535 nurses for palliative care knowledge, attitude, and practice were (16.29±1.99), (71.10±9.00), and (32.21±5.89), respectively. Multiple linear regression analysis revealed that hospital level, gender, and whether nurses have participated in on-the-job training on palliative care are influencing factors of nurses' knowledge of palliative care ( P<0.05) ; ethnicity and the duration of palliative care training courses attended within two years are influencing factors of nurses' attitude toward palliative care ( P<0.05) ; department is an influencing factor of nurses' practice of palliative care ( P<0.05) . Conclusions:Under the palliative co-care model in Zhejiang Province, nurses demonstrate a good attitude toward palliative care, while their knowledge and practice levels of palliative care still have room for improvement, with distinct influencing factors for each dimension-hospital level, gender, and on-the-job training participation affect knowledge; ethnicity and training duration within two years affect attitude; and department affects practice.

Comorbidities will be a challenge faced by both Chinese and Western medicine in the future.The coexistence of multiple diseases logically begins with a holistic view of life that integrates form,qi,and spirit,and a holistic view of disease that integrates dis-ease and syndrome.From a Chinese medicine perspective,the core pathogenesis of comorbidities involves the interaction between ab-normal qi transformation and physical damage.The key to treatment lies in restoring the disordered state of qi.The basis for formula se-lection is the formula-syndrome.The therapeutic goal of the formula-syndrome is not a specific disease,but rather a holistic differenti-ation and treatment of the entire body.The"formula-disease-person"diagnosis and treatment model for treating comorbidities is a model for innovative theoretical guidance in clinical practice.It offers three approaches to diagnosing and treating comorbidities:formu-la-disease correspondence,formula-person correspondence,and formula-disease and formula-person correspondence,which provides a more original perspective and broader thinking for the study of comorbidity.

Objective:To investigate the disease self-management status of patients with chronic obstructive pulmonary disease (COPD) and its influential factors, providing evidence for the development of effective management strategies.Methods:A total of 483 patients with chronic obstructive pulmonary disease (COPD) who received treatment at Wenshan People's Hospital from April 2023 to April 2024 were included in this study. Their disease self-management status was assessed, and one-way analysis of variance and multiple linear regression analysis were conducted to identify the factors influencing patients' self-management abilities.Results:Among the 483 patients studied, only 2.9% (14/483) showed a complete understanding of their disease, while 21.12% (102/483) had some understanding of how to manage it. Only 34.38% (166/483) of the patients used inhalants outside the hospital as required, of which only 40.96% (68/166) used them regularly as required by doctors, and 60.84% (101/106) of the patients inhaled correctly. One-way analysis of variance and multiple linear regression analysis results showed that the factors affecting patients' self-management included COPD classification, smoking, life satisfaction, disease self-cognition, exercise habits, lung function, and gender ( t = 2.35, -2.22, -5.76, 4.37, -2.22, 5.09, -3.64, all P < 0.05). Conclusions:Patients with COPD exhibit poor disease self-management awareness and medication compliance. Patient's ability to self-manage their disease is associated with COPD classification, lung function, smoking, exercise habits, gender, life satisfaction, and disease self-cognition. Therefore, it is essential to develop appropriate intervention measures based on these factors, focusing on enhancing patients' self-management awareness and abilities to improve their quality of life.
