Acute mitral regurgitation(MR)in the setting of myocardial infarction(MI)may be the result of papillary muscle rupture(PMR).The clinical presentation can be catastrophic,with refractory cardiogenic shock.This condition is associated with high morbidity and mortality.Transcatheter edge-to-edge repair(TEER)has become increasingly common in treating severe mitral regurgitation.This case details a successful TEER is feasible and safe in patients with acute MR following MI.TEER is an emerging treatment option in this clinical scenario that should be taken into consideration.

Objective To investigate knowledge,attitude and practice towards the fertility preservation of female cancer patients among clinical nurses in a cancer hospital,and to analyze influencing factors,so as to provide references for clinical implementation of related nursing services.Methods A self-designed questionnaire was delivered to 336 nurses working at a tertiary oncology hospital in Tianjin.Univariate analysis and multiple linear regression were used to analyze the factors influencing the knowledge,attitude,and practice level of female fertility preservation among nurses in a cancer hospital.Results In October 2022,a total of 291 nurses completed the questionnaires.The score of the knowledge,attitude and practice were(46.13±8.66),31.00(29.00,33.00),12.00(8.00,14.00),respectively,and the total score was(88.08±12.78).Multiple logistic regression analysis showed that education level,position,department types and whether or not getting the knowledge about fertility preservation of female cancer patients were the influencing factors for the total scores of knowledge,attitude and practice(P＜0.05).Conclusion Nurses who work at the cancer hospital have a positive attitude towards fertility preservation for female cancer patients,while their knowledge and practice level need be improved.Nursing administrators should attach importance to improving the knowledge level and practical ability of nurses in cancer hospitals to protect the fertility of female cancer patients,so as to promote the development of onco-fertility nursing in the future.

Objective To understand the experience of oncology nurses participating in fertility preservation services,and to provide a reference for oncology nurses to formulate targeted training courses and management measure.Methods From September to November 2023,phenomenological research methods were used to select 14 oncology nurses in a tertiary A cancer hospital in Tianjin for semi-structured interviews.Colaizzi 7-step analysis method was used to analyze the interview data and summarize the themes.Results 3 themes and 10 sub-themes were extracted:①The driving forces for participating in fertility preservation services(long-term benefits of fertility preservation,individual conditions of cancer patients,self-conscious cognition of role responsibilities,and internal drivers of empathy);②Oncology nurses are hampered by the lack of professional quality(knowledge system has not been built,ideological deviation needs to be corrected,communication skills need to be strengthened);③ The practical difficulties of oncology nurses participating in fertility preservation services(lack of targeted education and training,lack of multidisciplinary team contact channels,and lack of normative institutional guarantee).Conclusion Oncology nurses play an indispensable role in fertility preservation services.Hospitals need to pay attention to the unique role of oncology nurses and develop targeted training courses to improve their professional quality,so as to promote the implementation of fertility preservation services in China.

Objective: : Nicotinamide mononucleotide adenylyl transferase 2 (NMNAT2) is a crucial factor for the survival of neuron. The role of NMNAT2 in damage following traumatic brain injury (TBI) remains unknown. This study was designed to investigate the role of NMNAT2 in TBI-induced neuronal degeneration and neurological deficits in rats. Methods: : The TBI model was established in Sprague-Dawley rats by a weight-dropping method. Real-time polymerase chain reaction, western blot, immunofluorescence, Fluoro-Jade C staining, and neurological score analyses were carried out. Results: : NMNAT2 mRNA and protein levels were increased in the injured-side cortex at 6 hours and peaked 12 hours after TBI. Knocking down NMNAT2 with an injection of small interfering RNA in lateral ventricle significantly exacerbated neuronal degeneration and neurological deficits after TBI, which were accompanied by increased expression of BCL-2-associated X protein (Bax). Conclusion : NMNAT2 expression is increased and NMNAT2 exhibits neuroprotective activity in the early stages after TBI, and Bax signaling pathway may be involved in the process. Thus, NMNAT2 is likely to be an important target to prevent secondary damage following TBI.

Accumulating studies suggest that, as the subway is one of the important means of transport in cities, airborne microorganisms in its system have potential effects on human health, but previous studies have mainly focused on some foreign cities. We reviewed the spatio-temporal distribution characteristics of airborne microorganisms in subway stations in different cities, including diurnal, weekly, and seasonal variations, and the distribution of microorganisms in different regions of the world. The factors affecting airborne microorganisms, such as human activities, temperature and humidity, ventilation, and particulate matter, were presented. The potential health effects were described. Although there was no significant risk of infection from using subway, many pathogens do exist in the air. The influence of microorganisms in subway air on health has become a public health problem that cannot be ignored.

Objective To introduce and conduct effectiveness evaluation of peer-group level care and management mode in people living with HIV and AIDS(PLHAs)in Jing'an District, Shanghai. Methods We recruited PLHAs who were managed by Jing'an District and participated in the peer-group care activities from 2015 to 2016, and collected their data of general conditions, behavior, antiretroviral therapy, life quality, social support, mental status and medical modes, and then conducted effectiveness evaluation of the mode by multivariate logistic regression model and linear regression model. Results A total of 300 PLHAs were included with 150 cases in each group. PLHAs in target group had higher proportion of antiretroviral therapy[82.7%(124/150)and 64.7%(97/150)]. In addition, they got higher scores in mental health(48.5±9.2 and 43.9±10.6)and social support(28.7±8.2 and 24.8±6.6), and lower scores in depressive severity index(0.5±0.1)and avoidance of medical modes(16.1±3.0 and 17.0±2.5). Multivariate analysis showed that PLHAs in target group had less sex partners(zero partner, OR = 2.1, 95%CI:1.1-3.9;one partner, OR = 3.6, 95%CI:1.9-6.8)and increased condom use(no sex, OR = 5.3, 95%CI:2.4-11.7;complete use, OR = 10.6, 95%CI:4.7-24.1;random miss, OR = 5.1, 95%CI:1.8-14.8)in the last 12 months. Conclusion The effect of peer-group level care and management mode is significantly good in promoting behavior change, enhancing health concern and increasing antiretroviral therapy.

OBJECTIVE: To observe the effect of acupuncture-moxibustion on negative emotions and plasma tryptophan (Trip)-kynurenine (Kyn) metabolism in the patients with Crohn's disease (CD) at the mild and moderate active stage. METHODS: A total of 66 CD patients were randomized into an observation group (33 cases, 1 case dropped off) and a control group (33 cases, 2 cases dropped off). In the observation group, acupuncture was applied in combination with moxibustion. In the control group, the sham-acupuncture was used in combination with sham-moxibustion. In both of the observation group and the control group, acupuncture was applied to Zhongwan (CV 12), Shangjuxu (ST 37), Sanyinjiao (SP 6), Gongsun (SP 4), Hegu (LI 4), Quchi (LI 11), Taixi (KI 3) and Taichong (LR 3), and moxibustion was applied to Tianshu (ST 25) and Zusanli (ST 36). The treatment was given once every two days, 3 times a week, totally for 12 weeks. Separately, before and after treatment, the score of the hospital anxiety-depression scale (HADS) and the score of intestinal core symptoms (degree of abdominal pain and frequency of diarrhea) were observed in the patients of the two groups. The concentration of plasma indoleamine 2,3-dioxygenase 1 (IDO1) and the ratios of Kyn/Trp, QuinA/Kyn, KynA/Kyn and KynA/QuinA were compared between the two groups. RESULTS: Compared with before treatment, the scores of HADS-A and HADS-D in the observation group and the score of HADS-A in the control group were all reduced after treatment ( CONCLUSION Acupuncture and moxibustion relieve the negative emotions of anxiety and depression in CD patients at mild and moderate active stage, which is probably related to the regulation of plasma Trp-Kyn metabolic pathway.

Objective:To determine the prevalence of facility-based HIV testing and its associated factors among men who have sex with men （MSM） in Shanghai. Methods:From June 2018 to December 2020， MSM were recruited by a community organization “Shanghai CSW&MSM Center （SCMC）”. A total of 3 251 MSM were included as follows： being 18 years old and above， being HIV-negative or with unknown HIV status， living in Shanghai， had homosexual behavior in the past year， and completed informed consent. Using a self-designed questionnaire， we performed an online survey powered by www.wjx.cn to collect information on demographics， sexual behavior， and facility-based HIV testing. A total of 3 240 valid questionnaires were collected. Univariate and multivariate logistic regression were used to determine the factors associated with facility-based HIV testing. Results:A total of 3 240 MSM participated in the study with mean age of （29.7±6.2） years .The prevalence of facility-based HIV testing was 63.2% （2 049/3 240）， Multivariate logistic regression showed that the participants with a college degree or above were less likely to have facility-based HIV testing（OR=0.73，P=0.008）， compared to those with lower educational background. The proportion of the MSM who sought sexual partners through the internet received facility-based testing was 68.7%. Compared to the participants with the sexual role being 0 （only be penetrated）， those being 0.5 （both penetrated and be penetrated） and 1 （only penetrated） were both more likely to have the HIV testing （both P<0.05）. Those who used condoms during the last homosexual behavior were more likely to be tested than those who did not （OR=1.39， P=0.001）. Those who had been diagnosed with sexually transmitted diseases were more likely to be tested than those who did not （OR=2.05， P<0.001）. The participants who had used HIV self-testing kits in the past were more likely to be tested than those who did not （OR=2.31， P<0.001）. Conclusion:MSM in Shanghai have lower utilization of facility-based HIV testing， which may be improved by strengthening the advocacy of facility-based HIV testing services through the internet and peer education， and innovating service models.
