1Status of hyperhomocysteinemia in China: results from the China Stroke High-risk Population Screening Program, 2018显示文摘A nationwide survey was conducted from October 2018 to September 2019 to assess the prevalence of hyperhomocysteinemia(Hhcy)and its influencing factors in China.A standardized questionnaire was used to collect information.Hhcy was defined as the level of serum homocysteine(HCY)≥15.0µmol/L.The H-type hypertension(HHYP)was defined as hypertension with an elevated serum HCY(≥15.0µmol/L).Finally,110551 residents≥40 years of age from 31 provinces in the mainland of China were included.Overall,the median serum HCY level was 10.9µmol/L(interquartile range 7.9–15.1).A total of 28633 participants(25.9%)were defined as Hhcy.The Hhcy prevalence ranged from 7.9%in Shanghai to 56.8%in Tianjin.The data showed that serum HCY levels were associated with age,male gender,cigarette smoking,hypertension,diabetes,ethnicity,endurance in exercise(inverse),and fruit and vegetable intake(inverse).In addition,15486 participants were defined as HHYP,and the rate was 14.0%.HHYP was an independent predictor of stroke with an adjusted odds ratio of 1.752(95%CI 1.338–2.105).The geographical distribution pattern of the Hhcy epidemic reflects dynamic differences,and national strategies should be carried out to further improve the care of patients with Hhcy across China.Wenjun Tu Feng Yan Baohua Chao Xunming Ji Longde Wang 2021Frontiers of Medicine2021,15,6:12

3A microRNA encoded by HSV-1 inhibits a cellular transcriptional repressor of viral immediate early and early genes显示文摘Viral microRNAs are one component of the RNA interference phenomenon generated during viral infection. They were first identified in the Herpesviridae family, where they were found to regulate viral mRNA translation. In addition, prior work has suggested that Kaposi's sarcoma-associated herpesvirus (KSHV) is capable of regulating cellular gene transcription by miRNA. We demonstrate that a miRNA, hsv1-mir-H27, encoded within the genome of herpes simplex virus 1 (HSV-1), targets the mRNA of the cellular transcriptional repressor Kelch-like 24 (KLHL24) that inhibits transcriptional efficiency of viral immediate-early and early genes. The viral miRNA is able to block the expression of KLHL24 in cells infected by HSV-1. Our discovery reveals an effective viral strategy for evading host cell defenses and supporting the efficient replication and proliferation of HSV-1.WU WenJuan GUO ZhongPing ZHANG XueMei GUO Lei LIU LongDing LIAO Yun WANG JingJing WANG LiChun LI QiHan 2013Science China(Life Sciences)2013,56,4:6
4A comparative study of the characteristics of two Coxsackie A virus type 16 strains (genotype B)显示文摘Coxsackie A virus is one of the major pathogens associated with hand, foot and mouth disease (HFMD). The etiological characteristics of Coxsackie A virus type 16 (CA16) are thought to correlate with the pathological process of its infection. Two CA16 strains that were isolated from a severe HFMD patient presented with different plaque forms. This observation, along with biological analysis, indicated that the differences in the strains' biological characteristics, such as proliferation kinetics and immunogenicity, correlate with differences in their pathogenicity toward neonatal mice. Furthermore, these differences are thought to be associated with the sequence of the 5′ non-coding region of the viral genome and the VP1 structural region sequence. The results suggest that the biological and genetic characteristics of the CA16 viral strains are relevant to their pathogenicity.YANG ErXia ZHAO Heng ZHANG Ying LIU JianSheng LIAO Yun WANG LiChun CUI PingFang YANG LiXian LIU LongDing DONG ChengHong DONG ShaoZhong SHAO CongWen JIANG Li SUN Le LI QiHan 2012Science China(Life Sciences)2012,55,4:5
5Transcriptional regulation of the Herpes Simplex Virus 1α-gene by the viral immediate-early protein ICP22 in association with VP16显示文摘Herpes Simplex Virus 1 (HSV1) is capable of inducing two forms of infection in individuals, and the establishment of which type of infection occurs is linked to the transcriptional activation of viral α genes. One of the HSV1 α genes, ICP22, is known to have multiple functions during virus replication, but its distinct roles are still unclear. This study showed that ICP22 functions as a general repressor for certain viral and cellular promoters, and this transcriptional repression by ICP22 is independent of the specific upstream promoter element, as shown using the CAT enzyme assay system. Further work also found that VP16 interfered with ICP22 mediated transcriptional repression of the viral α4 gene, through interactions with specific elements upstream of the α4 gene promoter. These findings support the possibility that ICP22 and VP16 control transcription of HSV1α genes in a common pathway for the establishment of either viral lytic or latent infections.CUN Wei, GUO Lei, ZHANG Ying, LIU LongDing, WANG LiChun, LI JianFeng, DONG ChengHong, WANG JinJin & LI QiHan Institute of Medical Biology, Chinese Academy of Medical Sciences and Peking Union Medical College, Kunming 650118, China 2009Science China(Life Sciences)2009,52,4:4
6Pingwei capsules improve gastrointestinal motility in rats with functional dyspepsia显示文摘OBJECTIVE: To investigate the mechanism of Ping-wei capsules(PWC) in improving gastrointestinal m otility in rats with functional dyspepsia(FD).METHODS: We established an FD model by stimu-lating semi-starvation rats via tail damping, provo-cation, and forced exercise fatigue. The FD model group was further divided into five groups accord-ing to the treatment received: normal saline, dom-peridone, low-dose PWC, mid-dose PWC, or highdose PWC. The effect of PWC on FD was evaluated by measuring gastrointestinal motility. Changes in leptin and cholecystokinin(CCK) were detected through enzyme-linked immunosorbent assay, re-verse transcription-polymerase chain reaction, and immunohistochemistry.RESULTS: PWC significantly increased gastrointesti-nal m otility in FD rats. Furthermore, PWC signifi-cantly increased CCK m RNA and protein concentra-tions in the duodenum and antrum, decreased leptin protein concentrations in the duodenum, an-trum, and hypothalamus, and decreased CCK pro-tein concentration in the hypothalamus.CONCLUSION: PWC improves gastrointestinal mo-tor function in FD rats by decreasing the leptin con-centration in serum and the brain-gut axis, and by increasing the CCK concentration in gastrointesti-nal tissue. Our findings help to elucidate the mech-anism of FD and provide further insight into the pharmacokinetics of PWC.Liang Qiankun Mao Lanfang Du Xiaojuan Li Yunxia Yan Yuan Liang Jingjing Liu Junhong Wang Longde Li Hongfang 2018Journal of Traditional Chinese Medicine2018,38,1:3
7HSV-1 stimulation-related protein HSRG1 inhibits viral gene transcriptional elongation by interacting with Cyclin T2显示文摘The protein encoded by HSRG1(HSV-1 stimulation-related gene 1) is a virally induced protein expressed in HSV-1-infected cells.We have already reported that HSRG1 is capable of interacting with transcriptional regulator proteins.To further analyze the effects of HSRG1 on the regulation of viral gene transcription,we expressed the HSRG1 protein in transfected cells and found that it postpones the proliferation of HSV-1.CAT(chloramphenicol acetyltransferase) assays also revealed that HSRG1 reduces transcription from HSV-1 promoters.Yeast two-hybrid and immunoprecipitation assays indicated that HSRG1 interacts with Cyclin T2,the regulatory subunit of P-TEFb,which is required for transcription elongation by RNA Pol II(RNAP II) ,and that amino acid residues 1-420 in Cyclin T2 are important for binding with HSRG1.Fluorescence assays suggested that the cellular localizations of those two proteins are influenced by their interaction.Further analyses with CAT assays revealed that HSRG1 inhibits the transcriptional activation by Cyclin T2 of viral promoters.Our results suggested that the inhibitory effects of HSRG1 on viral replication and proliferation are probably induced by its binding to Cyclin T2.Therefore,it is likely that HSRG1 inhibits viral gene transcriptional elongation by interacting with Cyclin T2.WU WenJuan YU Xian LI WeiZhong GUO Lei LIU LongDing WANG LiChun LI QiHan 2011Science China(Life Sciences)2011,54,4:3
8Consensus for prevention and management of coronavirus disease 2019 (COVID-19) for neurologists显示文摘Coronavirus disease 2019(COVID‐19)has become a pandemic disease globally.Although COVID-19 directly invades lungs,it also involves the nervous system.Therefore,patients with nervous system involvement as the presenting symptoms in the early stage of infection may easily be misdiagnosed and their treatment delayed.They become silent contagious sources or‘virus spreaders’.In order to help neurologists to better understand the occurrence,development and prognosis,we have developed this consensus of prevention and management of COVID‐19.It can also assist other healthcare providers to be familiar with and recognise COVID-19 in their evaluation of patients in the clinic and hospital environment.Huijuan Jin Candong Hong Shengcai Chen Yifan Zhou Yong Wang Ling Mao Yanan Li Quanwei He Man Li Ying Su David Wang Longde Wang Bo Hu 2020Stroke & Vascular Neurology2020,5,2:3
9Analysis of HSV-I ICP22 effects on HCMV major immediate-early promoter structure显示文摘The human cytomegalovirus (HCMV) major immediate-early (MIE) promoter has strong transcriptional promoting capability. Its cis-acting regulatory elements form a special structure in this region that is repeated multiple times; the biological significance of these elements and their different compositions in the transcriptional promoting process remain unclear. Our results demonstrate that the HSV-I MIE protein ICP22 can generate strong repression of many viral and cellular promoters and enhancers. We further studied the transcriptional effects of ICP22 on structural elements and mutations in various HCMV MIE promoters by using a CAT assay. In spite of different transcriptional effects of all the ele- ments in the presence of ICP22, the transcriptional efficiencies exhibited by mutations generated by different compositions and an entire HCMV promoter, are not the simple sum of the functions of these elements. Furthermore, the transcriptional activities of specific sequences were not affected by the presence of ICP22. Therefore, it is assumed that the HCMV MIE promoter co-regulates expression of downstream genes by using viral and cellular specific factors via a specific pathway.LUO Jie, CUN Wei, CHE YanChun, WANG LiChun, LI WeiZhong, LIU LongDing & LI QiHan Institute of Medical Biology, Chinese Academy of Medical Sciences and Peking Union Medical College, Kunming 650118, China 2007Science China(Life Sciences)2007,50,3:2
10Immediate-early gene product ICP22 inhibits the trans-transcription activating function of P53-mdm-2显示文摘As a product of HSVI immediate-early gene, ICP22 is capable of interacting with various cellular tran-scriptive and regulatory molecules during viral infection so as to impact the normal cellular molecular mechanism. ICP22 expressed in transfected cells can push the cells’ entering into S phase with binding to mdm-1 promoter region and impact its trans-transcription activating effect by P53. Consequently, the MDM-2 binds to P53, and the degradation effects by the ubiquitous pathway are decreased, improving indirectly the P53 levels in cells and making the cells progress into the S phase.GUO HongXiong, CUN Wei, LIU LongDing, WANG LiChun, ZHAO HongLing, DONG ChengHong & LI QiHan Department of Viral Immunology, Institute of Medical Biology, CAMS and PUMC, Kunming 650118, China These authors contributed equally to this work 2007Science China(Life Sciences)2007,50,4:2
