【Abstract】 With the changes in living standards and dietary structure，the incidence of hyperuricemia is on the rise.Epidemiological studies show that the prevalence of hyperuricemia in adults is 8.4% - 13.3% in China.A large number of studies have shown that hyperuricemia is not only the main cause of gout，but also an independent risk factor for the progression of chronic kidney disease（CKD） and cardiovascular death.It has become one of the metabolic diseases that threaten human health.Mineral and bone disorder are common complications of CKD，including mineral metabolism disorders，bone lesions and extra-osseous calcification，which can lead to increased hospitalization，cardiovascular events and mortality in patients with CKD.Recent studies have found uric acid may be closely related to CKD-mineral and bone disorder （CKD-MBD），but the correlation is still controversial and further researches are needed.This article reviews the pathophysiological function of uric acid，the relationship between uric acid and CKD-MBD and the recent advances of their interaction mechanism.It is suggested that the regulation of uric acid level may be the target of CKD-MBD therapy.

【Abstract】 Background Detection of atherosclerosis in the elderly can assess the risk of cardiovascular and cerebrovascular diseases early and monitor the clinical efficacy.Transforming growth factor-beta 1（TGF-β1） and connective tissue growth factor（CTGF） have been identified as key factors of tissue fibrosis.However，there are little research on its correlation with vascular sclerosis in the elderly.Objective To analyze the relationship between TGF-β1 and CTGF in elderly patients with atherosclerosis，and to explore the feasibility of using TGF-β1，CTGF combined with brachial-ankle pulse wave velocity（BaPWV） and carotid ultrasound as indexes for evaluating arterial vascular pathological changes and monitoring clinical efficacy in the elderly.Methods A total of 134 elderly patients，who sought medical advice in Department of Geriatrics and Cardiology of Jiangyin People's Hospital from September 2017 to September 2018，were selected and divided into arteriosclerosis group（69 cases） and normal control group（65 cases） according to the standard of BaPWV or carotid ultrasound diagnosis of atherosclerotic plaque.The BMI，blood pressure，levels of total cholesterol（TC），triglyceride（TG），high density lipoprotein cholesterol（HDL-C），low density lipoprotein cholesterol（LDL-C），urea nitrogen（BUN），serum creatinine（Scr） and glycosylated hemoglobin（HbA1c） were compared between the two groups.Serum levels of TGF-β1 and CTGF were detected by enzyme-linked immunosorbent assay（ELISA）．The incidence of hypertension，diabetes mellitus，cerebrovascular disease and coronary heart disease were compared between the two groups.Results Systolic blood pressure（SBP），mean arterial pressure（MAP），HbA1c and BaPWV in arteriosclerosis group were higher than those in control group（P<0.05）．There was no significant difference in the serum level of TGF-β1 between arteriosclerosis group and control group（Z=-1.499，
P=0.134），while the serum level of CTGF in arteriosclerosis group was significantly higher than that in control group
（Z=-3.250，P=0.001）．The morbidities of hypertension，diabetes mellitus and cerebrovascular disease in arteriosclerosis group were significantly higher than those in normal control group（P<0.05），but there was no significant difference in the morbidity of coronary heart disease between the two groups（P>0.05）．Conclusion The serum level of CTGF in elderly patients with arteriosclerosis increased significantly.Therefore，CTGF combined with BaPWV and carotid ultrasound can be used as indexes for evaluating arterial vascular pathological changes and monitoring clinical efficacy in the elderly.

【Abstract】 Background Available surveys show that about 55% to 75% of stroke survivors worldwide have limb dysfunction，which directly affects the motor function and daily living activities，and brings great mental stress and physical pain.Functional rehabilitation after stroke is one method to effectively reduce the disability rate.Virtual reality technology（VR） is one of the most widely used rehabilitation methods in recent years，which is safe，effective and timely responsive.However，clinical evaluation of its effectiveness and safety is not the same.Objective To systematically overview the systematic reviews（SR）/meta-analyses of the effectiveness and safety of VR for stroke rehabilitation.Methods Databases of PubMed，EMBase，the Cochrane Library（2018，Issue 6），CNKI，Wanfang Data，CBM and VIP were searched as of June 2018 and the SR/meta analyses based on VR for stroke rehabilitation were collected.Literature screening and data extraction were performed by two reviewers independently.AMSTAR was used to evaluate the methodological quality of the included articles.The GRADE system was used to evaluate the quality of evidence for main outcome indicators reported in the articles.Results Finally，10 SR/meta analyses were included，involving 7 major outcome indicators.AMSTAR evaluation results showed that only two studies were of high quality and the other eight studies were of medium quality.The major problems of methodological quality assessment were lack of pre-design planning，omission of the status of publications of the included articles，lack of the list of excluded articles and the explaining of the conflicts of interest.Qualities of the evidence for indicators measuring 6 outcomes （the upper limb motor function，limb mobility，functional mobility，balance function，gait speed and the participation） were mainly graded as "medium"，and those for indicators related to stride length were mainly graded as "low".Three studies showed good VR safety and no adverse reactions，and one study showed that a small number of studies reported pain，headache or dizziness，but no serious adverse reactions were found.Conclusion The methodological quality of included studies is unsatisfied，with a low grade of evidence.VR has good safety and can be used as a short-term clinical assistant rehabilitation for stroke patients.However，there are still some controversies about its long-term effectiveness.A large number of high-quality tests are needed to prove its long-term effectiveness and safety.Clinicians should be cautious when using the evidence for rehabilitation.
