Stroke is the leading cause of death and long-term disability worldwide,and cognitive impairment and dementia are major complications of ischemic stroke.Cystatin C (CysC) has been found to be a neuroprotective factor in animal studies.However,the relationship between CysC levels and cognitive dysfunction in previous studies has revealed different results.This prospective observational study investigated the correlation between serum CysC levels and post-stroke cognitive dysfunction at 3 months.Data from 638 patients were obtained from the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS).Cognitive dysfunction was assessed using the Mini-Mental State Examination (MMSE) at 3 months after stroke.According to the MMSE score,308 patients (52.9%) had post-stroke cognitive dysfunction.After adjusting for potential confounding factors,the odds ratio (95% CI) of post-stroke cognitive dysfunction for the highest quartile of serum CysC levels was 0.54 (0.30–0.98),compared with the lowest quartile.The correlation between serum CysC and cognitive dysfunction was modified by renal function status.We observed a negative linear dose-response correlation between CysC and cognitive dysfunction in patients with normal renal function (Plinearity = 0.044),but not in those with abnormal renal function.Elevated serum CysC levels were correlated with a low risk of 3-month cognitive dysfunction in patients with acute ischemic stroke,especially in those with normal renal function.The current results suggest that CysC is a protective factor for post-stroke cognitive dysfunction,and could be used to treat post-stroke cognitive dysfunction.The CATIS study was approved by the Institutional Review Boards at Soochow University from China (approval No.2012-02) on December 30,2012,and was registered at ClinicalTrials.gov (identifier No.NCT01840072) on April 25,2013. 展开更多

Stromal cell-derived factor-1 and its receptor CXCR4 are essential regulators of the neurogenesis that occurs in the adult hippocampal dentate gyrus.However,the effects of CXCR7,a new atypical receptor of stromal cell-derived factor-1,on hippocampal neurogenesis after a stroke remain largely unknown.Our study is the first to investigate the effect of a CXCR7-neutralizing antibody on neurogenesis in the dentate gyrus and the associated recovery of cognitive function of rats in the chronic stage of cerebral ischemia.The rats were randomly divided into sham,sham+anti-CXCR7,ischemia and ischemia+anti-CXCR7 groups.Endothelin-1 was injected in the ipsilateral motor cortex and striatum to induce focal cerebral ischemia.Sham group rats were injected with saline instead of endothelin-1 via intracranial injection.Both sham and ischemic rats were treated with intraventricular infusions of CXCR7-neutralizing antibodies for 6 days 1 week after surgery.Immunofluorescence staining with doublecortin,a marker for neuronal precursors,was performed to assess the neurogenesis in the dentate gyrus.We found that anti-CXCR7 antibody infusion enhanced the proliferation and dendritic development of doublecortin-labeled cells in the dentate gyrus in both ischemic and sham-operated rats.Spatial learning and memory functions were assessed by Morris water maze tests 30-32 days after ischemia.CXCR7-neutralizing antibody treatment significantly reduced the escape latency of the spatial navigation trial and increased the time spent in the target quadrant of spatial probe trial in animals that received ischemic insult,but not in sham operated rats.These results suggest that CXCR7-neutralizing antibody enhances the neurogenesis in the dentate gyrus and improves the cognitive function after cerebral ischemia in rats.All animal experimental protocols and procedures were approved by the Institutional Animal Care and Use Committee of China Medical University(CMU16089 R)on December 8,2016. 展开更多

BACKGROUND:Hospital mortality rates are higher among patients with sepsis-associated acute kidney injury(SA-AKI)than among patients with sepsis.However,the pathogenesis underlying SA-AKI remains unclear.We hypothesized that the source of infection affects development of SA-AKI.We aim to explore the relationship between the anatomical source of infection and outcome in patients with SA-AKI.METHODS:Between January 2013 and January 2018,113 patients with SA-AKI admitted to our Emergency Center were identifi ed and divided into two groups:those with pulmonary infections and those with other sources of infection.For each patient,we collected data from admission until either discharge or death.We also recorded the clinical outcome after 90 days for the discharged patients.RESULTS:The most common source of infection was the lung(52/113 cases,46%),followed by gastrointestinal(GI)(25/113 cases,22.1%)and urinary(22/113,19.5%)sources.Our analysis showed that patients with SA-AKI had a significantly worse outcome(30/52 cases,P<0.001)and poorer kidney recovery(P=0.015)with pulmonary sources of infection than those infected by another source.Data also showed that patients not infected by a pulmonary source more likely experienced shock(28/61 cases,P=0.037).CONCLUSION:This study demonstrated that the source of infection infl uenced the outcome of SA-AKI patients in an independent manner.Lung injury may influence renal function in an asyet undetermined manner as the recovery of kidney function was poorer in SA-AKI patients with a pulmonary source of infection. 展开更多

Objective: To investigate the effects of retrograde intrarenal surgery (RIRS) and Mini-percutaneous nephroscope lithoipsy (Mini-PCNL) on liver and kidney function, endocrine changes and trauma in patients with upper ureteral calculi. Methods: 100 patients with upper ureteral calculi admitted to our hospital from March 2016 to February 2018 were selected. They were randomly divided into observation group (RIRS group) and control group (Mini-PCNL group), with 50 cases in each group. The observation group was given RIRS, while the control group was given Mini-PCNL. At the same time, the expression levels of the liver function [including alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma transpeptidase (gamma-GT)], renal function [including urea nitrogen (BUN) and serum creatinine (Scr) levels], endocrine changes [including corticotropin (ACTH), cortisol (Cor), norepinephrine (NE)] and trauma related indexes [Including soluble vascular cell adhesion molecule-1 (sVCAM-1) and erythrocyte sedimentation rate (ESR)] were analyzed and compared between the two groups. Results: There was no significant difference in ALT, AST, γ-GT, BUN and Scr before and after operation between the two groups. The difference was not statistically significant (P>0.05). After operation, the levels of ACTH (27.37±3.29) pg/mL, Cor (150.09±18.47) ng/mL, NE (165.48±26.74) ug/L and sVCAM-1, (596.55±56.24) ng/mL in RIRS group were significantly lower than those in Mini-PCNL group ((38.42±4.33) pg/mL, (222.37±28.70) ng/mL, (287.26±25.29) ug/L and (820.62±72) mL)The differences were statistically significant (P<0.05). While the ESR level in RIRS group (8.29±0.63) mm/h was significantly higher than that in Mini-PCNL group (7.16±0.68) mm/h, and the differences were statistically significant (P<0.05). Conclusions: There is no significant difference in the liver and renal function between RIRS and Mini-PCNL in the treatment of upper ureteral calculi.

Objective: To explore the effects of Ticagrelor on oxidative stress, coagulation function, platelet function and related factors in patients with coronary artery disease undergoing interventional therapy. Methods: A total of 140 patients with coronary artery disease who underwent percutaneous coronary intervention in our hospital from October 2016 to March 2018 were selected as the study subjects and were divided into control group (70 cases) and observation group (70 cases) by drawing lots. Both groups were treated with symptomatic routine therapy before operation. On this basis, the control group was treated with clopidogrel before operation, and the observation group was treated with Ticagrelor before operation on the basis of routine treatment. The changes of oxidative stress, coagulation index, platelet function and related factors were compared between the two groups before and after treatment. Results: Before treatment, there were no significant differences in oxidative stress factors, coagulation parameters, platelet parameters and related factors factors between the two groups. After treatment, the levels of MDA, MPAR, VEGF and MMP-9 in the two groups were lower than those before treatment, while the levels of SOD, APTT, TT and PT were higher than those before treatment;and the levels of MDA, MPAR, VEGF, MMP-9, APTT and PT in the observation group were significantly lower than those in the control group after treatment, while the levels fo SOD, TT and IPA in the observation group were significantly higher than those in the control group. Conclusions: Ticagrelor can better reduce oxidative stress injury, improve coagulation function and coronary stenosis, and inhibit platelet aggregation in patients with coronary heart disease undergoing PCI than clopidogrel. It has clinical popularization significance. 展开更多

Objective: To investigate the effects of Liraglutide on endothelial function, immune function and related factors in patients with type 2 diabetes mellitus. Methods: A total of 160 patients with type 2 diabetes mellitus who received treatment in department of endocrinology of our hospital from December 2015 to June 2018 were collected. They were randomly divided into the control group and the observation group, 80 cases in each group. The patients in the control group were treated with metformin. The patients in the observation group were treated with liraglutide on the basis of the control group. The levels of endothelin (ET-1), nitric oxide (NO), immunoglobulin A (IgA), immunoglobulin M (IgM), immunoglobulin G (IgG), hypersensitive C-reactive protein (hs-CRP), insulin-like growth factor-1 (IGF-1), tumor necrosis factor- (TNF-α), Vaspin and HbAlc were detected and compared. Results: After treatment, compared with the treatment group, the serum levels of ET-1, hs-CRP, IGF-1, TNF-α and HbAlc of patients in the control group and the observation group were significantly decreased, and the levels of NO, IgA, IgG, IgM and Vaspin increased significantly. The change trend of the above indexes of patients in the observation group was more obvious than those in the control group (P<0.05). Conclusion: Liraglutide combined with metformin in the treatment of type 2 diabetes mellitus can significantly enhance endothelial function and immune function of patients, and alleviate inflammation, and it has good clinical efficacy. 展开更多

Objective: To evaluate the effect of tai chi exercise on cardiac and static lung function for older community-dwelling adults at risk of ischemic stroke. Methods: A total of 170 older community-dwelling adults (aged 55–75 years old) at risk of ischemic stroke were allocated to either tai chi training group (85 cases, five 60-min sessions of tai chi training per week for 12 weeks) or control group (85 cases, usual pbysical activity for 12 weeks) using a computer-generated randomization. The echocardiographic parameters of cardiac structure, cardiac function and static lung function were measured at baseline, after 12 weeks of intervention and additional 12-week follow-up period by a blinded professional staff member using a color Doppler ultrasound imaging device or a cardiopulmonary function instrument. The t test and linear mixed model based on the intention-to-treat analysis principle was used to calculate the effect. The adverse effect was observed. Results: Most of echocardiographic parameters on the cardiac structure, cardiac function and static lung function between the tai chi group and control group did not have a significant difference either post 12-week intervention or additional 12-week follow-up period. Only three parameters involving in right ventricular diameter (P=0.024), main pulmonary artery diameter (P=0.002) and vital capacity maximum (P=0.036) were beneficial to be improved in the tai chi group compared to the control group by the analysis of mixed linear model. No adverse effects were found during the intervention period. Conclusions: The 12-week tai chi exercise did not have an obvious beneficial effect on cardiac structure, cardiac function and static lung function in older community-dwelling adults at risk of ischemic stroke.(Trial registration No. ChiCTR-TRC-13003601) 展开更多

We present optical luminosity functions(LFs) of galaxies in the0.1 g,0.1 r,0.1 i bands, calculated using data in40 deg2 sky area of the LAMOST Complete Spectroscopic Survey of Pointing Area(LaCoSSPAr) in the Southern Galactic Cap. Redshifts for galaxies brighter than r = 18.1 were obtained mainly with LAMOST. In each band, LFs derived using both parametric and non-parametric maximum likelihood methods agree well with each other. In the0.1 r band, our fitting parameters of the Schechter function are φ*=(1.65 ± 0.36) × 10-2 h3 Mpc-3, M*=-20.69 ± 0.06 mag and α =-1.12 ± 0.08,which agree with previous studies. Separate LFs are also derived for emission line galaxies and absorption line galaxies. The LFs of absorption line galaxies show a dip at0.1 r 18.5 and can be fitted well by a double-Gaussian function, suggesting a bimodality in passive galaxies. 展开更多

Objective: Analyze the effect of argatroban on neurological function in patients with acute cerebral infarction and explore its possible mechanisms. Methods: From August 2015 to August 2017, 140 patients with acute cerebral infarction who were admitted to the Department of Neurology in our hospital were divided into a control group and an observation group according to the lottery method, with 70 cases in each group. Patients in the conventional group received routine treatment. Patients in the treatment group received routine treatment plus argatroban. The changes of neurological function, coagulation function and inflammatory factors were observed in the two groups. Result: Before treatment, there were no significant differences in neurological function parameters, coagulation function indexes and inflammatory factors between the two groups. After treatment, the neurological function indexes NT-proBNP, NPY and S-100β levels, coagulation function index FIB level, inflammatory factor indicators MMP-9, Lp-PLA2 and Hcy, vascular endothelial function index ET levels decreased, coagulation Functional indicators PT, TT and APTT are both elevated, and NO and CGRP levels are elevated. The levels of NT-proBNP, NPY and S-100β, FIB level, MMP-9, Lp-PLA2 and Hcy, ET levels in the treatment group were lower than those in the conventional group, while the levels of PT, TT and APTT levels, and NO and CGRP levels were higher than the conventional group. Conclusion: Argatroban treatment can significantly improve neurological function in patients with acute cerebral infarction. The possible mechanism is to improve coagulation function, vascular endothelial function and relieve inflammatory stress response. 展开更多
