| 1 | Effects of donor cells on in vitro development of cloned bovine embryos显示文摘The donor cells from different individuals and with different foreign genes introduced were investigated to determine their effects on the efficiency of somatic cell nuclear transfer (SCNT). The bovine ear fibroblast from different individuals was isolated, cultured, and then transfected with foreign genes to establish the stable cell lines, which were used as donor cells for nuclear transfer. The oocytes were obtained through ovum pick up operation. After in vitro maturation, the M II phase oocytes were selected as receptors for nuclear transfer. The reconstructed embryos were cultured in vitro and observed at 2 h, 48 h, and 7 days after transfer to assess the rate of fusion using cleaved and blastocyst as the parameters of SCNT efficiency. The donor cells from different individuals (04036, 06081, 06088, and 06129) had no obvious effect on the fusion and cleaved rate, whereas there was significant difference in the blastocyst rate (P<0.05), and the rate was 62.3%, 37.0%, 35.1%, and 15.6%, respectively. There was no significant difference among the rate of fusion, cleaved and blastocyst in donor cells with different foreign genes (P>0.05). It was concluded that the genetic background of the donor cells could affect the effi- ciency of SCNT, while the introduction of foreign genes into the donor cells had no obvious effect on the efficiency. This study provides useful information for the SCNT and would benefit in promoting the efficiency. | Jing Fu Pengfei Guan Leiwen Zhao Hua Li Shuzhen Huang Fanyi Zeng Yitao Zeng | 2008 | Journal of Genetics and Genomics2008，35，5： | 6 |
| 2 | Correlates of Sexual Lifestyles Among Older Adults Living With HIV in China: Findings From the Sexual Well-being (SWELL) Study显示文摘Sexual lifestyles are closely related to overall human health and well-being.Few studies have focused on sexual lifestyles among older adults living with HIV(OALHIV),especially in low-and middle-income countries.This study is a part of the sexual well-being among older adults in China(SWELL)study,which is a multicenter cross-sectional study focused on sexual health among older adults aged 50 years and older.Participants were 680 OALHIV(≥50 years old)from the SWELL study conducted from June 2020 to December 2022.Data were collected through one-on-one interviews.We used logistic regression to assess the correlates of sexual activity and sexual satis-faction.Among all participants,37.1%were sexually active.Being older,male,in a steady relationship and employed were associated with being sexually active.The prevalence of sexual satisfaction was 69.8%among sexually active OALHIV.Being homosexual and reporting a better general health status were associated with sexual satisfaction.The OALHIV who have depressive symptoms were less likely to report sexual satisfaction.To support holistic healthy aging among OALHIV,it is important for healthcare providers to be educated about the importance of enquiring about sexual activity,satisfaction and problems and addressing concerns while conveying sex-positive attitudes during clinical reviews,as these are still critical aspects of their health and well-being. | Bingyi Wang Xin Peng Leiwen Fu Xinyi Li Tongxin Shi Bowen Liang Tian Tian Thomas Fitzpatrick Zhen Lu Weijie Zhang JunyeBian Xin Xiao YingWang Yunlong Ao Lin Ouyang YongCai Maohe Yu Guohui Wu Linghua Li Xiaojun Meng Huachun Zou | 2023 | Infectious Microbes & Diseases2023，5，3： | 1 |
| 3 | Burdens Attributable to Intimate Partner Violence in Women Aged 15 Years or Older—China,1990–2019显示文摘Summary What is already known about this topic?Intimate partner violence(IPV)represents a significant global public health concern.What is added by this report?The burden of HIV/AIDS related to IPV demonstrated an upward trend from 1990 to 2019,exhibiting an annual growth of 4.66%in age-standardized death rates(ASDR)and 4.42%in age-standardized disabilityadjusted life years(DALYs)rates.Notably,the age groups 30–34 and 50–54 experienced a higher IPV burden compared to other age groups.What are the implications for public health practice?There is a pressing need for public health policymakers to develop efficacious interventions aimed at bolstering the surveillance and prevention of IPV targeted at women in China. | Leiwen Fu Tian Tian Zhen Lu Bingyi Wang Xinyi Li Weijie Zhang Yanxiao Gao Yinghui Sun Huachun Zou | 2023 | China CDC weekly2023，5，16： | 0 |
| 4 | Oral Sexual Behavior Among HIV-Infected Men Who Have Sex with Men--China,February 2021显示文摘Summary What is already known about this topic?Unprotected oral sex carries a risk of the transmission of sexually transmitted infections(STIs),especially if the individual has poor oral health.What is added by this report?Most human immunodeficiency virus(HIV)infected men who have sex with men(MSM)had never used a condom when giving oral sex(89.30%,718/804)or receiving oral sex(90.32%,709/785).Among MSM with detectable viral loads who had ever received oral sex without a condom,40.00%reported ejaculation in their partner’s mouth. | Leiwen Fu Jin Zhao Weiran Zheng Yinghui Sun Tian Tian Bingyi Wang Luoyao Yang Xinyi Zhou Yi-Fan Lin Zhengrong Yang Hui Li Huachun Zou | 2022 | China CDC weekly2022，4，25： | 0 |
| 5 | Sexual Risk Behavior and Satisfaction Among Men Who Have Sex With Men Living With Detectable HIV Viral Loads:A Nationwide Online Survey in China显示文摘Little is known about sexual behavior and satisfaction among men who have sex with men(MSM)with detectable HIV viral loads(VL)in China.This study aims to investigate sexual risk behavior and sexual satisfaction among MSM living with HIV in China,as well as poten-tial predictors.This cross-sectional study was conducted in February 2021 using an anonymous online survey based on WeChat.Data were collected on sociodemographics,sexual behavior,HIV clinical information,sexual satisfaction and mental health.Descriptive sta-tistics,logistic regression and multivariable logistic regression were performed.MSM with detectable HIV VL(VL+)or VL not sure were more likely to report inconsistent condom use,even with HIV-negative/unknown-status regular male partners.Having an HIV-positive regular partner and recreational drug use were positively associated with inconsistent condom use during anal sex among MSM with undetectable VL(VL-).Alcohol use before or during sexual activities was positively associated with inconsistent condom use during anal sex among VL+or VL not sure MSM.A total of 58.3%of participants reported being sexually satisfied.MSM living with HIV who were currently employed,had experienced anal sex in the prior 6 months,had VL-HIV status,or had more frequent ejaculation during sex/masturbation were more likely to report sexual satisfaction.The development of targeted education and interventions to minimize sexual risk behavior among MSM living with HIV is in dire need.Treating sexual dysfunction and developing a reasonable antiretroviral therapy regimen to achieve viral suppression can help promote sexual satisfaction in MSM living with HIV. | Leiwen Fu Bingyi Wang Tian Tian Xinyi Zhou Zhen Lu Yinghui Sun Weiran Zheng Yanxiao Gao Yi-Fan Lin Hui Li Huachun Zou | 2023 | Infectious Microbes & Diseases2023，5，3： | 0 |
