ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

Proteome is defined as all proteins expressed in a cell, a tissue or an organism. Proteomics, a science of understanding the life activity law at the whole protein level, takes proteome as a research object; it is also a scientific method for quantitative detection of one or more protein populations or proteomes in a cell or tissue. Cerebral ischemic preconditioning has been one of the research hotspots in the field of neuroscience for decades. Its neuroprotec-five mechanism is associated with the changes of protein expression levels after cerebral ischemia, Therefore, proteomics has become more and more important in its mechanism study. This article mainly presents the major techniques of proteomics and their application in the studies of cerebral ischemic preconditioning.

Objective To evaluate the methodological quality of clinical trials on Chinese medicine interventional chemothera-py induced gastrointestinal toxic reactions from 2000 to 2014.Methods The randomized controlled trials(RCT)and semi-RCT on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions were retrieved from the China National Knowledge Infrastructure (CNKI),Wanfang databases,VIP,China Biology Medicine Database (CBM)and Traditional Chinese Medicine (TCM)database by computer and supplemented by the manual retrieval (January 2000 to December 2014).The methodo-logical quality assessment on the included RCT and semi-RCT was conducted by using the Cochrane risk assessment table of bias. Results 291 articles were finally screened out,only 76 of RCT and semi-RCT were conformed to the at least one of low risk stand-ards of Cochrane risk assessment table of bias.Therefore the total methodological quality was not good enough.Conclusion The publishing of clinical trials on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions shows the in-creasing trend year by year during the past 14 years.However,the different defects exist in the overall trial design.

AIM:To explore the role of α7 nicotinic acetylcholine receptor (α7nAChR) in anti-inflammation of glucocorticoids (GCs) at physiological concentrations .METHODS: MTT assay was used to measure the viability of BV-2 cells, which were processed by hydrocortisone at different concentrations .On the basis of inflammatory model induced by LPS in BV-2 cells, experimental groups were divided as follows:(1) control;(2) LPS;(3) GCs+LPS;(4) methyl-lycaconitine ( MLA)+GCs+LPS.The levels of TNF-αand IL-1βin the cell supernatants were detected by ELISA .RE-SULTS:Hydrocortisone at concentrations of 2 000 and 1 000 nmol/L decreased the cell viability to (76.9 ±5.5)% and (90.8 ±7.3)%, respectively, indicating the cellular injury by GCs at over-physiological doses.LPS significantly induced the releases of TNF-αand IL-1βin a time-and dose-dependent manner in BV-2 cells.Hydrocortisone at physiological con-centrations (500 and 250 nmol/L) reduced the releases of TNF-αand IL-1βin BV-2 cells stimulated by LPS, and MLA at concentration of 10 nmol/L antagonized the anti-inflammatory effect of GCs .CONCLUSION:α7nAChR is involved in the anti-inflammatory effect of the physiological concentrations of GCs .

Objective To investigate the effect of Atorvastatin Combined Naoxintong Capsule treats to cerebral infarction and carotid atherosclerosis.Methods 134 patients with cerebral infarction and carotid atherosclerosis were diagnosed by MRI or CT scan.They were randomly divided into two groups.67 cases were given atorvastatin versus aspirin received routine treatment in the control group and 67 cases were used Naoxintong capsule in observation group on the basis of routine treatment in the observation group.The blood lipid,serum high sensitive C-reactive protein (hs-CRP) level,neural function defect score (NIHSS),carotid artery intima-media thickness (IMT) were comperred before and after treatment in two groups for treated with 1 courses (6 months).Results The blood lipid had no significant difference between two groups before and after treatment (P ＜ 0.05).The IMT,NIHSS score of high sensitivity C-reactive protein levels had no significant difference in two groups before and after treatment (P ＜ 0.05).The scores of NIHSS,IMT,high sensitive C-reactive protein level respectively (10.08 ± 1.82) ％,(1.06 ± 0.13)mm,(3.89 ± 1.41) mg/L of observation group were more decreased significantly than the control group (respectively (13.92 ±2.01)％,(1.24 ±0.15)mm,(5.02 ± 1.52) mg/L after treatment.Conclusion Atorvastatin Combined Naoxintong Capsule in treatment of cerebral infarction and carotid artery gruel kind hardening shows good therapeutic effect,it is worth for clinical use.

Based on the necessity of carrying out bioethics education to the probationer nurses, this paper put forward to introduce psychological sitcom to the probationer nurses′ bioethics education and described the practice process in detail. It also discussed the mechanism to improve the effectiveness of bioethics education from the per-spectives of creation, dramatization, and performance of psychological sitcom.

Toll-like receptors (TLRs) can recognize pathogens associated molecular of micro-organisms,leading to activation of the downstream signal transduction pathway and participate in innate and adaptive immune response.TLRs can also recognize endogenous danger signaling molecule and therefore be involved in pathogenesis of many low-grade chronic inflammatory and autoimmune diseases.TLRs are always expressed on immune cells,and recent studies confirmed that retinal pigment epithelial (RPE) cells also express TLRs.This review focuses on the research progress of fundus diseases and TLRs,such as the recognition of exogenous pathogenic microorganisms and endogenous danger signals in fundus,induction of inflammatory response,phagocytosis of photoreceptor outer segment by RPE and angiogenesis of fundus diseases.
