Objective To systematically evaluate the relationship between atherosclerotic renal artery stenosis (ARAS) and cor‐onary artery disease (CAD) and peripheral arterial disease (PAD) .Methods We gathered all case‐control studies about the correla‐tion of ARAS with CAD and PAD in the following databases:Cochrane library ,PubMed ,EMBASE ,Web of science until April , 2014 .Two reviewers extracted all relevant datas from the screened documents independently according to exclusion and inclusion criteria ,RevMan 5 .2 software were used to conduct Meta‐analysis .Results Fourteen trials were included .Meta‐analysis showed that :the OR (95% CI)of CAD with 1 vascular lesions ,2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD and ARAS were 0 .70(0 .59-0 .82) ,1 .28(1 .10 -1 .48) ,2 .09(1 .69 -2 .59) ,1 .82(1 .40 -2 .36) ,3 .68(2 .21 -6 .10) with statistical signifi‐cance (P<0 .05) .Conclusion CAD with 2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD were connected with ARAS ,CAD with 1 vascular lesions has little relationship with ARAS .

Objective To investigate the association of serum ghrelin level with cognition, hippocampal volume, and proton magnetic resonance spectrum ( [ 1 H ]-MRS ) in patients with type 2 diabetes mellitus ( T2DM) . Methods The T2DM patients cared at the Wuhan Fourth Hospital were recruited. Data on demographic characteristics and clinical parameters were collected. Ghrelin was measured by ELISA assay. Cognitive performance was assessed by the Montreal Cognitive Assessment ( MoCA ) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The changes of metabolites in hippocampus were detected by [1 H]-MRS, including N-acetyl asparate ( NAA) , choline ( Cho) , myo-inositol ( MI) , creatine ( Cr) . All patients were divided into 2 groups[cognitive impairment (CI) and non-cognitive impairment (NCI) groups] by MoCA. Results (1) Compared with patients in NCI group, the serum ghrelin level, bilateral hippocampal volume, and NAA/Cr ratio of [1H]-MRS metabolites in CI group were decreased, but MI/Cr and Cho/Cr ratios were increased(all P<0.05). (2) Serum ghrelin was positively correlated with a variety of RBANS scores ( including immediate memory, attention, delayed memory, and total scores) , bilateral hippocampal volume, and NAA/Cr ratio of [ 1 H]-MRS metabolites in T2DM patients, but it was negatively correlated with MI/Cr ratio and Cho/Cr ratio ( all P<0. 05 ) . ( 3 ) Logistic regression analysis showed that ghrelin was a protective factor of cognition in T2DM patients. Conclusions T2DM patients with cognitive impairment had lower levels of ghrelin, and serum ghrelin was postively correlated with their cognitive performance, hippocampal volume, and [1 H]-MRS metabolites, suggesting that serum ghrelin may be involved in the occurrence and development of cognitive dysfunction in patients with T2DM.

BACKGROUND: Men who have sex with men (MSM) have become a high risk population of HIV infection due to their risky sexual behaviors. The latent pattern of psychosocial characteristics plays an important effect in HIV-related risky behaviors among HIV-negative MSM. METHOD: Participants were recruited from Wuhan, Nanchang, and Changsha city from September 2017 to January 2018. Social support was assessed by the multidimensional scale of social support, Connor-Davidson Resilience scale-10 items for reliance, the assessment of Stigma towards Homosexuality for sexual minority stigma, the Likert subscale of nondisclosure for identity concealment, the ACE questionnaire-Kaiser-CDC for adverse childhood experience, the Centers for Epidemiological Studies Depression Scale for depression. Latent profile analysis (LPA) and multivariate regression were used to analyze the data. RESULTS: Three psychosocial characteristic patterns were revealed by the LPA. "Social support and resilience group" (SR group), "Identity concealment group" (IC group) and "Adverse childhood experience" (ACE group) were identified, respectively. In comparison with "SR group", "IC group" have a higher likelihood of one-night male partners (AOR = 2.74, 95%CI = [1.54, 4.90]), both fixed and one-night male partners (AOR = 2.01, 95%CI = [1.34, 3.01]) and HIV-unsure male partner (AOR = 2.12, 95%CI = [1.44, 3.13]). Similarly, "ACE group" were more likely having inconsistent condom use (AOR = 2.58, 95%CI = [1.41, 4.73]), and having sex with HIV-positive male partner (AOR = 4.90, 95%CI = [1.95, 12.30]) with comparison of "SR group". In addition, we further revealed that "ACE group" had a higher ratio (90.0%) of inconsistent condom use among MSM whose male partners were HIV-positive. CONCLUSIONS Six important psychosocial factors were divided into three latent pattern classes. Compared with "SR group", "IC group" and "ACE group" were more likely to engage in HIV-related risky sexual behaviors. Further research may pay more attention to "IC group" and "ACE group" for targeted intervention.
