AIM: To observe the changes of morphology, the activity of myeloperoxidase (MPO) and membrane pump activities of spleen tissue in acute renal failure (ARF) rabbits, and to inquire into the role of spleen on pathogenesis of immune function disorders during ARF. METHODS: 42 rabbits were divided into control group, HgCl_2 group and glycerinum group. The ARF model was established by hypodermic injection of 1% HgCl_2 at dose of 1.3 mL/kg in HgCl_2 group, intramuscularly injection of 50% glycerinum at dose of 10 mL/kg in glycerinum group, respectively, and the animals were divided into the 12 h, 24 h, 48 h secondary groups (6 rabbits each group). At different time points, the rabbits were cannulated to facilitate the collection of blood sample to examine the biochemical indexes of renal function. The spleen microscopic sections were prepared for observing the morphology. The spleen homogenate was made for determining the activities of MPO and membrane pumping. RESULTS: Pathological sections of spleen showed that the different degree of congestion was found and spleen trabecula was increased in two model groups at multiple-time points. The MPO activity of spleen homogenate in HgCl_2 group and glycerinum group at all time points were obviously higher than that in control group, and at 24 h, the MPO activitie in two model groups was significantly increased than that in the same group at 12 h and 48 h. The activities of Na~+-K~+-ATPase, Ca~(2+)-ATPase, Mg~(2+)-ATPase, Ca~(2+)-Mg~(2+)-ATPase of spleen homogenate in two model groups at multiple time points were significantly lower than those in control group. Following ARF development, the ATPase activitie in two model groups at 48 h was lower than that at 12 h except the Mg~(2+)-ATPase in glycerinum group. CONCLUSION: Spleen as an immune organ has histological damage, arrest of polymorphonuclear neutrophils and dysfunction of membrane pump during the development of ARF in rabbits, leading to immune disorders.

Objective To investigate the therapeutic efficacy of the combined therapy of daoyin prescription and cognitive training on vascular dementia(VD).Methods Totally 75 patients with VD were randomly divided into 3 treatment groups:daoyin prescription,cognitive training and two combined treatments(n =25 each) for 3 months.Mini mental state examination(MMSE),Loewenstein occupational therapy cognitive assessment(LOTCA)and activities of daily living scale(ADL)were used for assessing therapeutic efficacy among three treatment groups.Results There were no significant differences in baseline clinical data among the three groups (P ＞ 0.05),possessing data comparability.Scores of MMSE,LOTCA,ADL and LOTCA subitems of orientation,visual perception,spatial perception,visual movement,thinking operation and attention were significantly improved in the 3 groups after 3 months intervention versus pre-treatment with three treatments(all P＜0.01).There were significant differences in scores of MMSE,LOTCA,ADL and LOTCA subitems of orientation,visual perception,visuo-motor organization and attention between combination therapy group versus daoyin prescription group and cognitive training group (all P ＜ 0.05).Conclusions Combined treatments of daoyin prescription and cognitive training have better effect on vascular cognitive function in patients with and VD.It can markedly improve the activities of daily living and cognitive function.It is worthy of further research in clinical medicine.

Objective:To assess the possibility of suicide in setting condition among urban and rural residents samples in northern China.Methods:By randomly sampling,1007 persons aged 18 years or older were selected from 10 urban neighborhoods in Beijing and from 10 rural village in Hebei province.The Survey Schedule of Atti-tudes in China in which 24 negative life events were listed,and the possibility of committing suicide was asked to the subjects when they encountered the supposed events.Results:The rates of thinking about committing suicide when encountered the supposed life events were 65.2% of incurable illness,62.0% of burden on other and no future hope,61.2% of drug dependence,57.3% of large debt due to gambling,54.2% of being raped, 51.6% of severe depression,50.7% of being elderly and no family to provide support.Only 14.6% of the ur-ban and rural residents would not consider suicide when encountered any type of supposed problems.Conclusion:There is higher possibility of considering suicide in urban and rural residents when encountered negative life events, so it is important to give support to the residents with one or more life events.

Objective To investigate the relationship of the neutrophil/lymphocyte ratio (NLR) on admission and angiographic no-reflow phenomenon in patients with ST-segment elevation myocardial infarction (STEMI) who had undergone primary percutaneous coronary intervention (PCI).Methods 232 patients who had undergone PCI between 2010 and 2013,were included and divided into two groups based upon the thrombolysis in myocardial infarction (TIMI) flow gradings.No-reflow was defined as post-PCI TIMI Grade 0,1 and 2 flows (group Ⅰ).Normal-flow was defined as TIMI 3 flow (group Ⅱ).Receiver operating characteristic curve (ROC) analysis was used to identify the predictive effect of NLR on no-reflow phenomenon.Relationship of NLR and no-reflow was assessed by multivariate logistic regression.All statistical calculations and analyses were performed using SPSS 11.0.Results NLR was significantly higher in group Ⅰ (n=45) compared with group Ⅱ (n=187) [4.1 (2.4-6.5) vs.2.4 (1.7-3.8),P=0.001].In ROC analysis,NLR＞3.2 predicted no reflow with 80％ sensitivity and 73％ specificity.Patients with elevated NLR had a higher incidence of no-reflow phenomenon than those with non-elevated NLR (34.8％ vs.9.3％,P＜0.001).Also,NLR (＞3.2) was an independent predictor of no-reflow development [odds ratio 3.70,95％ confidence interval (1.39-9.80),P=0.009].Conclusion NLR was an independent predicator for no-reflow development in STEMI patients who had undergone PCI.This simple and low-cost parameter could provide useful information for the early risk evaluation on these patients.

Vascular cognitive impairment(VCI)is a group of syndromes ranging from mild cognitive impairment to dementia caused by cerebrovascular disease,due to the lack of sensitivity and specific biomarkers,it is difficult to identify and diagnose early.Abnormal connectivity is observed in brain regions of patients with vascular cognitive disorders,locates mainly in the default mode network(DMN),and changes in their abnormal functional connectivity correlated with the degree of patients' cognitive impairment.Resting-state functional magnetic resonance imaging(rs-fMRI)is a commonly used method to detect the internal activity of the brain at resting state.The use of various rs-fMRI to study abnormal changes in the DMN in patients with VCI is useful to further investigate the pathogenesis of VCI and provide an objective basis for imaging.This article mainly reviews the application of rs-fMRI in the DMN in patients with VCI,bringing new perspectives for the correct diagnosis and assessment of VCI.

Objective To compare the efficacy between left radial approach (LRA) and right radial approach (RRA) for coronary angiography (CAG).Methods The following databases were searched,including PubMed,Embase,Web of science,Cochrane Library,CBM,VIP,Wanfang databases and CNKI,from creation of database to January 2013.Two reviewers extracted data independently,according to inclusive criteria,exclusion criteria and methods of Cochrane Collaboration.Statistical analysis was performed using Review Manager Software (RevMan 5.1).Results Eleven trials with 5 442 patients were included in the systematic review.The results of meta-analysis showed that when compared with RRA,LRA did not increase the failure rate of the procedures (OR =1.04,95％ CI 0.80-1.35,P ＞ 0.05) and amount of contrast medium(mean difference =2.39,95％ CI-0.30-5.08),P ＞ 0.05).However,LRA was superior to RRA in reducing fluoroscopy time (standardized mean difference =0.15,95％ CI0.06-0.24,P ＜ 0.01).In addition,the incidence of severe tortuosity of subclavian artery was significantly lower with LRA (OR=4.65,95％CI 1.98-10.88,P＜0.01).Conclusions Based on the current evidence,LRA shares similar safety with RRA for CAG and is superior to RRA in certain respects.LRA can thus be used either as an alternative approach or routine approach for CAG.
