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 clinical efficacy of pelvic floor biofeedback combined with electroacupuncture therapy in the treatment of chronic pelvic floor pain syndrome (CPPS).Methods:Ninety CPPS patients admitted to the Dongguan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine from August 2022 to July 2023 were selected prospectively, and they were divided into two groups by random number table method, each group with 45 cases. The control group received pelvic floor biofeedback treatment alone, while the observation group received pelvic floor biofeedback combined with electroacupuncture treatment. The two groups were treated once a day, 10 times as a course of treatment. After two courses of treatment, the clinical efficacy, pain degree before and after treatment, inflammatory factor levels, SF-36 health questionnaire (SF-36) scores, pelvic floor surface myoelectric parameters, and incidence of adverse reactions were compared between the two groups.Results:The total effective rate in the observation group after treatment was higher than that in the control group: 95.56% (43/45) vs. 75.56% (34/45), there was statistical difference ( χ2 = 7.28, P<0.05). After treatment, the visual analogue scale (VAS) scores, levels of procalcitonin (PCT), interleukin-6 (IL-6) and C-reactive protein (CRP) in the two groups were decreased, and SF-36 scores were increased, there were statistical differences ( P<0.05); the VAS scores, PCT, IL-6 and CRP levels in the observation group were lower than those in the control group, and SF-36 scores was higher than that in the control group: (2.11 ± 0.24) scores vs. (2.87 ± 0.34) scores, (0.92 ± 0.08) ng/L vs. (1.26 ± 0.09) ng/L, (24.08 ± 2.52) μg/L vs. (28.49 ± 3.10) μg/L, (4.55 ± 0.51) mg/L vs. (6.06 ± 0.63) mg/L, (74.55 ± 7.29) scores vs. (70.18 ± 7.80) scores, there were statistical differences ( P<0.05). After treatment, the surface muscle potential of pelvic floor muscle were increased in the front resting stage, rapid contraction stage, tension contraction stage, endurance contraction stage and post-resting stage, and the above parameters in the observation group were higher than those in the control group: (3.56 ± 0.34)μV vs.(3.20 ± 0.37) μV, (35.26 ± 3.05) μV vs. (31.47 ± 3.08) μV, (34.22 ± 3.25) μV vs. (31.15 ± 3.01)μV, (29.77 ± 3.17) μV vs. (27.04 ± 2.68) μV, (3.21 ± 0.27) μV vs. (3.00 ± 0.34) μV, there were statistical differences ( P<0.05). The incidence rate of adverse reactions in the two groups had no statistical difference ( P>0.05). Conclusions:Pelvic floor biofeedback combined with electroacupuncture in the treatment of CPPS has good clinical effect, and can relief pain response, regulate the inflammatory response and pelvic floor function, and have high safety.

Objective To investigate the karyotypes and the correlation of chromosomal abnormalities in the fetuses with increased nu-chal translucency(NT),so as to provide a basis for prenatal genetic counseling.Methods The clinical data of 386 singleton pregnant women with NT≥2.5mm who underwent invasive prenatal diagnosis at the First Affiliated Hospital of Nanjing Medical University from January 2018 to April 2022 were retrospectively analyzed.The fetuses were grouped according to NT thickness(2.5-3.4,3.5-3.9,4.0-4.9,5.0-5.9,and ≥6.0 mm),fetal ultrasound abnormalities(isolated increased NT,non-isolated increased NT),and maternal age(advanced age ≥35 years,non-advanced age＜35 years).The chi-square test was used to compare the differences of the incidence of fetal chromosomal abnormalities among various groups.Results Among the 386 fetuses with increased NT,chromosomal abnormalities were detected in 87 cases with an overall detection rate of 22.5％(87/386),including chromosomal numerical abnormalities accounted for 82.8％(72/87)and copy number variations(CNVs)accounted for 17.2％(15/87).The detection rates of chromosomal abnormal-ities and numerical abnormalities increased with NT thickness(P＜0.05),while no statistically significant difference of CNV abnormali-ty rates was found(P=0.41).The detection rates of chromosomal abnormalities(36.5％)and CNV abnormalities(14.1％)in the non-isolated increased NT group were significantly higher than those in the isolated increased NT group(18.6％and 1.0％,respective-ly,both P＜0.05).The detection rates of chromosomal abnormalities(34.7％)and numerical abnormalities(31.6％)in the fetuses of advanced maternal age mothers with increased NT were significantly higher than those in the non-advanced age group(18.4％and 14.2％,respectively,both P＜0.05).However,the difference of CNV abnormality rates between the two groups was not statistically sig-nificant(P=0.62).Conclusion The detection rate of fetal chromosomal abnormalities elevated with increased NT thickness.Ad-vanced maternal age and the presence of other ultrasound abnormalities were the high-risk factors for fetal chromosomal abnormalities.The risks of CNV abnormalities may not be significantly correlated with NT thickness or maternal age but associated with the presence of other ultrasound abnormalities.

This study aims to simultaneously detect three antibiotic resistance genes(blaNDM,mcr-1 and cfr).A triplex fluorescence quantitative PCR method was established.Plasmids,primers and probes were designed and optimized.The method could specifically detect blaNDM,mcr-1 and cfr,but not other antibiotic resistance genes.The R2 of the standard curves of the three antibiotic re-sistance genes were all greater than 0.999,and the coefficients of variation were all lower than 1％.The lowest detection limits of the plasmids were 1 × 102 copies/μL.This method was used to de-tect 800 bacterial samples.The results showed that 32 samples contained mcr-1 gene,40 samples contained blaNDM gene,2 samples contained cfr gene,8 samples contained both mcr-1 and blaNDM genes.There were no samples carrying three antibiotic resistance genes detected.The results indica-ted that the triplex fluorescence quantitative PCR method established in this experiment had the advantages of high sensitivity,specificity and stability.It was suitable for rapid detection of blaNDM,mcr-1 and cfr antibiotic resistance genes in clinical practice.It provided a convenient and quick method basis for the detection of antibiotic resistance genes.

Objective:To investigate exercise fear condition and its influencing factors in patients with coronary heart dis-ease(CHD)involving in phase Ⅱ cardiac rehabilitation after percutaneous coronary intervention(PCI).Methods:Conven-ience sampling was performed among cardiac rehabilitation patients from a Shanxi grade-A tertiary hospital between Janu-ary 2023 and June 2023.General data questionnaire,Tampa Scale for Kinesiophobia-Short Version for Heart patients(TSK-SV H),the Multidimensional Scale of Perceived Social Support(MSPSS)and the Post Percutaneous Coronary In-tervention Health Literacy Scale(PPCIHLS)were used for assessment.Pearson and Spearman rank correlation analyses were applied to investigate the relationships between social support factors and health literacy factors with patients'fear of exercise;multivariate linear regression models and quantile regression models were used to analyze the influencing factors of fear of exercise.Results:Among the 118 patients,average TSK-SV H score was(33.78±3.79)points;10.2％patients showed significant fear.The correlation analysis showed that PPCIHLS score was negatively correlated with TSK-SV H score(r=-0.423,P＜0.001).Results from multivariate regression analysis indicated that health literacy,cardiac func-tion class and drinking status affected the average score of exercise fear(P＜0.05 all).The quantile regression model pro-vided additional insights,showing that the impact of factors such as living situation,drinking status,cardiac function class and health literacy on exercise fear varied across different quantiles.Notably,cardiac function class had a consistently posi-tive effect on TSK-SV H score at various quantiles.Conclusion:Improving health literacy and tailored rehabilitation plans are vital to reduce exercise fear and improve cardiac rehabilitation effect.
