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 observe the clinical efficacy of against-lateral correction Tuina(Chinese therapeutic massage)in treating atlanto-axial joint disorder(AAJD)and imaging changes.Methods:A total of 142 patients with AAJD were recruited.They were randomly allocated to a trial group and a control group using the random number table method,with 71 participants in each group.The trial group was treated with against-lateral correction Tuina 3 times weekly.The control group was offered conventional physical traction therapy once daily.The interventions lasted 2 weeks in both groups.The two groups of participants were observed before and after treatment for their changes in the global pain scale(GPS)score,visual analog scale(VAS)score for dizziness assessment,cervical range of motion(ROM)in rotation,and the extent of atlanto-dental displacement.Results:The GPS and VAS scores dropped after treatment in both groups(P<0.05)and were lower in the trial group than in the control group after treatment and at the follow-up(P<0.05).Participants in the trial group achieved a significant increase in the cervical ROM in rotation after treatment and at the follow-up compared to the pre-treatment value(P<0.05)and surpassed the control group(P<0.05);the control group only showed an increase in the left-side rotation(P<0.05).After the intervention,neither the intra-group nor the between-group comparison revealed significant differences in the extent of atlanto-dental displacement(P>0.05),though the trial group presented an improving tendency.Conclusion:Compared to physical traction,the against-lateral correction Tuina method works more significantly in improving pain,dizziness,and ROM in AAJD patients.

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 examine the interaction between interpersonal issues and eating behavior problems among college freshmen, and to identify core psychological factors and potential pathways that drive eating behavior.Methods:In October 2019, a total of 5 073 college freshmen from a university in Shanghai were recruited as participants. Their general demographic data were collected, and they were evaluated using the eating disorder examination questionnaire 6.0 (EDE-Q 6.0) and inventory of interpersonal problems-32(IIP-32).Descriptive analyses were performed using SPSS 24.0 software.A regularized partial correlation network was constructed using the graphical least absolute shrinkage and selection operator (GLASSO) in R(v4.2.3) software. A Bayesian network analysis (BNA) was conducted to build a directed network, aiming to identify core driving factors and key psychological mechanisms.Results:Regularized partial correlation network identified shape concern as the most central node, with the highest strength centrality(1.32) and expected influence(1.20). It showed the highest bridge strength with dominance/control (0.22, 0.21), linking the interpersonal and eating behavior modules. Directed network analysis indicated that low self-confidence was the upstream node influencing social inhibition and cold/ distant relationships, indirectly affecting eating disorder.Within the eating module, shape concern and weight concern predicted eating preoccupation and dietary restraint, forming a pathway structure from eating cognition to behavior.The network demonstrated good stability (CS-coefficient=0.75).Conclusion:Shape concern is the core mechanism underlying eating problems in college freshmen. Low self-confidence contributes indirectly via interpersonal dysfunction. Dominance/control and shape concern bridge interpersonal and eating domains, providing key targets for early prevention and intervention.

Hepatocellular carcinoma(HCC),as the most common type of liver cancer,poses a significant threat to global public health due to its high incidence and mortality rates.This paper delves into the etiology,pathogenesis,and syndrome differentiation of liver cancer from the perspective of"dispersing qi and fortifying the body resistance",based on the clinical experience of renowned traditional Chinese medicine(TCM)practitioner,Prof.Changquan Ling.Prof.Ling believes that the development of liver cancer is closely related to the disruption of liver qi flow,the accumulation of blood stasis over time,and the generation of toxin from long-term stagnation,accompanied by pathological changes such as imbalance of yin and yang,deficiency of the body's vital qi and accumulation of pathogenic factors,and internal blazing of cancer toxins.In terms of treatment,he emphasizes the principles of dispersing qi and fortifying the body resistance,addressing both the root cause and symptoms.This is achieved by regulating the functions of viscera,improving the stagnation of qi flow,and supplemented by methods such as clearing heat and detoxifying,and softening and dispersing hard masses,aiming to break the vicious cycle of qi stagnation,deficiency of vital qi,and pathogenic factor generation,thereby promoting the recovery from the disease.Through detailed analysis of clinical cases,this paper demonstrates Prof.Ling's unique insights and significant efficacy in treating liver cancer through"dispersing qi"to"fortify the body resistance",ultimately achieving"tumor suppression".This provides new references and perspectives for the clinical diagnosis and treatment of liver cancer in TCM.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
