Objective To investigate the distribution characteristics of cerebral artery stenosis and its risk factors in patients with acute ischemic stroke.Methods The patients with acute ischemic stroke examined with MRI and magnetic resonance angiography (MRA) were divided into either a stenosis group or a non-stenosis group according to whether they had cerebral artery stenosis or not.The patients in the stenosis group were redivided into a simple intracranial stenosis,simple extracranial stenosis,and intracranial + extracranial stenosis subgroups according to their stenotic sites; they were redivided into either a young and middle-aged subgroup (＜60) or an elderly subgroup (≥60) according to their age; they were redivided into either a single-branch lesion subgroup or multibranch lesion subgroup according to the number of vascular stenosis.The distribution characteristics and influencing factors of cerebral artery stenosis were analyzed.Results A total of 232 patients with acute ischemic stroke were enrolled,and 114 of them (62.0％) were simple intracranial stenosis,30 (16.3％) were simple extracranial stenosis,and 40 (21.7％) were intracranial+ extracranial stenosis.The patients with anterior circulation stenosis (76.6％) were more common than those with posterior circulation stenosis (33.7％).They were mainly in the middle cerebral artery (64.4％) and posterior cerebral artery (53.8％) respectively.Multivariate logistic regression analysis showed that age (odds ratio [OR] 1.049,95％ confidence interval [CI] 1.015-1.084; P =0.005),hypertension (OR 10.063,95％ CI 4.402-23.004; P ＜ 0.001),diabetes (OR 3.873,95％ CI 1.141-13.147; P =0.030),smoking (OR 3.311,95 ％ CI 1.112-9.855; P =0.031),and fibrinogen (OR 6.085,95％ CI 1.396-26.533; P=0.016) were the independent risk factors for cerebral artery stenosis in patients with acute ischemic stroke; hypertension (OR 10.779,95％ CI 4.468-26.007; P＜ 0.001),diabetes (OR 3.593,95％ CII.018-12.685; P =0.047),and smoking (OR 4.408,95％ CI 1.403-13.826; P =0.011) were the independent risk factors for simple intracranial artery stenosis; hypertension (OR 6.143,95％ CI 1.838-20.537; P=0.003),diabetes (OR 8.179,95％ CI 1.844-36.287; P=0.006),and fibrinogen (OR 2.410,95％ CI 1.046-5.551; P =0.039) were the independent risk factors for simple extracranlal artery stenosis.C reactive protein (CRP) level of the intracranial + extracranial stenosis group was significantly higher than that of the simple intracranial stenosis (P=0.001) and simple extracranial stenosis (P =0.018) groups.There was no significant difference between the two groups,but the mean level of the 3 groups was higher than that of the normal value.The simple intracranial stenosis and the simple extracranial stenosis were most common in the young and middle-aged group,and the simple intracranial stenosis and the intracranial + extracranial stenosis were more common in the elderly group.The age (P=0.036) and uric acid level (P=0.006) in the subgroup of multiple branches stenosis were significantly higher than those in the subgroup of single branch stenosis,but only age (OR 1.030,95％ CI 1.003-1.057; P =0.028) was significantly independent correlated with the multiple branches stenosis.Conclusions Intracranial artery stenosis is common in cerebral artery stenosis of patients with acute ischemic stroke.The proportion of intracranial + extracranlal stenosis increases sfightly with age.Age,hypertension,diabetes,smoking,and fibrinogen are the independent risk factors for cerebral artery stenosis in patients with acute ischemic stroke.Hypertension and diabetes are the common independent risk factors for simple intracranial and extracranial artery stenosis in patients with acute ischemic stroke.Smoking is an independent risk factor for simple intracranial artery stenosis in patients with acute ischemic stroke.Fibrinogen is a simple independent risk factor for extracranial artery stenosis in patients with acute ischemic stroke.CRP and uric acid may be the inflammatory predictive factors associated with the patients with acute ischemic stroke and cerebral artery stenosis.

Objective To discuss the effect of comprehensive mental intervention on mental health and sleep quality among the crew members during the Escort Mission in the Gulf of Aden.Methods The same batch of two escort ships was divided into study group and control group.The study group was intervened by comprehensive psychological intervention methods involving diversified forms of psychological training, counseling, behavioral intervention and cooperation between various departments.A psychological survey was conducted with Symptom Checklist 90( SCL-90) , Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS) and Pittsburgh Sleep Scale(PSQI) before and 3 months after intervention. Results There was no significant difference between the two groups before intervention (P>0.05).After intervention,the score of SCL-90 of study group was significantly better than that of the control group in somatization,obsessive compulsive disorder,interpersonal relationship,depression, anxiety,bigotry and hostility (P<0.05), while the score of SAS and SDS was lower(P <0.05).Sleep quality, the time taken to fall asleep, sleep time, dyssomnia,sleep efficiency,daytime dysfunction factor and the total score of PSQI were significantly more desirable than in control group (P<0.01).Conclu-sion Comprehensive intervention can effectively improve mental health and sleep quality of the crew members in the escort mission in the Gulf of Aden.It is worthy of popularization and application.

Objective To investigate the correlation between the plasma homocysteine (Hcy) level and intra/extracranial artery stenosis in patients with ischemic stroke.Methods The medical history,baseline clinical data,imaging and Hcy and other laboratory test results in patients with ischemic stroke were collected.The patients were divided into either a stenosis group or a non-stenosis group according to magnetic resonance angiography.The artery stenosis group was further redivided into an isolated intracranial stenosis group,an isolated extracranial stenosis group,and combined extracranial and intracranial stenosis group.The relationship between plasma Hcy level and intra/extracranial stenosis was analyzed.Results A total 147 patients with ischemic stroke were enrolled,including 115 patients in the stenosis group and 32 in the non-stenosis group.There were significant differences in age (t =4.577,P ＜ 0.001),the plasma levels of Hcy (t =3.65,P ＜ 0.001),C-reactive protein (t =2.06,P =0.041),low-density lipoprotein cholesterol (LDL-C) (t =1.896,P =0.046),high-density lipoprotein cholesterol (HDL-C) (t =-4.261,P ＜ 0.001),as well as the proportions of diabetes mellitus (x2 =5.772,P =0.016),hypertension (x2 =10.507,P =0.001) and smoking (x2 =12.282,P ＜ 0.001) between the stenosis group and the non-stenosis group.Multivariate logistic regression analysis showed that age ≥60 years (odds ratio [OR] 3.374,95％ confidence interval [CI] 1.351-8.426; P=0.009),Hcy ＞15 mmol/L (OR 2.274,95％ CI 1.147-8.173; P=0.025),hypertension (OR 5.782,95％ CI 2.045-16.345; P =0.001),and smoking (OR 3.514,95％ CI 1.200-10.293; P=0.002) were the independent risk factors,while HDL-C ＞ 1.0 mmol/L was an independent protective factor for intra/extracranial stenosis (OR 0.166,95％ CI 0.054-0.511; P =0.002).The stenosis group was redivided into an isolated extracranial stenosis group (n =24),an isolated intracranial stenosis group (n =61) and a combined extracranial and intracranial stenosis (n =30) according to the sites of stenosis.The comparison of the clinical data and risk factors among the three groups showed that there were significant differences in the proportions of patients with hypertension (x2 =7.024,P=0.003),as well as the plasma levels of LDL-C (F =3.276,P =0.042) and C-reactive protein (F =3.645,P =0.029).Multivariate logistic regression analysis showed that hypertension was the common independent risk factor for isolated intracranial stenosis (OR 3.795,95％ CI 1.261-11.424; P =0.018),isolated extracranial artery stenosis (OR 18.490,95％ CI 3.117-10.966; P=0.001) and combined extracranial and intracranial stenosis (OR 9.178,95％ CI2.211-38.094; P=0.002),and the increased HDL-C level was the common protective factor for isolated intracranial artery stenosis (OR 0.150,95％ CI 0.043-0.523; P =0.003),isolated extracranial artery stenosis (OR 0.078,95％ CI 0.012-0.488; P=0.006) and combined extracranial and intracranial stenosis (OR 0.089,95％ CI 0.021-0.385; P=0.001).Age was an independent risk factor for isolated intracranial stenosis (OR 6.351,95％ CI 2.277-17.717; P ＜ 0.001).The increased LDL-C level was an independent risk factor for isolated extracranial stenosis (OR 6.021,95％ CI 1.212-29.917; P =0.028).The increased Hcy level was an independent risk factor for isolated extracranial stenosis (OR 4.376,95％ CI 1.026-18.671; P-0.046) and combined extracranial and intracranial stenosis (OR 4.951,95％ CI 1.378-17.783; P =0.014).Conclusions The increased plasma Hcy level correlated with extracranial stenosis.

Objective To screen and identify the phage-display random 7 amino acid peptide specific to the systemic lupus erythematosus(SLE) and analyze its practical significance. Methods Using the phage random 7 peptide library screening, the SLE specific phage clones are obtained after binding with the mixture of sera from 30 SLE patients and 30 normal controls as ligand respectively. Then the Dot-ELISA is used to identify the SLE specific phage clones reactive to sera of the SLE patients and normal controls individually. Finally the identified phage-display random 7 amino acid peptides are sequenced and it's homology with the antigenic epitope of human being and other are also analyzed. Results Total 12 of the phage-display random 7 amino acid peptide are obtained by phage peptide library screening and the Dot-ELISA identification. Sequence analysis shows that the identified phage-display random 7 amino acid peptide epitope have homology with E. coli, Salmonella and human immunodeficiency virus, but not with that of human being. Conclusion SLE-specific peptides screened by phage random peptide library maybe used to diagnosis the SLE. Meanwhile, the antibodies in SLE patients which are combined with the Pathogen epitope, suggest that SLE maybe relate to pathogen infection.
