Objective To investigate the different characteristics of vertebral basilar artery between isolated vertigo and dizziness with ischemic stroke history by magnetic resonance angiography (MRA) information,and find the independent risk factors of isolated vertigo.Methods From January 2015 to January 2016,isolated vertigo patients from our department were enrolled in study group (vertigo group),and dizzy patients with ischemic stroke history in control group (dizziness group).The patient's general information,and the relevant vascula data of the MRA were statistically analyzed to find the risk factors.Results A total of 118 patients with isolated vertigo was enrolled in the vertigo group,and 74 patients with dizziness after ischemic stroke were used as a control group.There were significant statistical differences in mean diameter of the right vertebral artery,rate of stenosis of basilar artery,vertigo history,the left vertebral artery hypoplasia,basilar artery skewing,and basilar artery hypoplasia between two groups (P ＜ 0.05).Multivariate logistic regression analysis showed that vertigo history (P =0.049,OR =3.822,95％ CI =1.004 ～ 14.548),the right vertebral artery hypoplasia (P =0.001,OR =6.083,95％ C1 =2.193 ～ 16.876),the left vertebral artery hypoplasia (P =0.006,OR =5.110,95 ％ CI =1.615 ～ 16.170),and mean diameter of the right vertebral artery (P =O.000,OR =3.143,95％ CI =1.724 ～ 5.730) were independent risk factors for isolated vertigo,and basilar artery skewing (P =0.018,OR =O.436,95％ CI =0.219 ～ O.866),and degree of basilar artery stenosis (P =0.006,0R =0.634,95％ CI =0.459 ～0.877) were the protective factors.Conclusions The right vertebral artery hypoplasia,the left vertebral artery hypoplasia,and mean diameter of the right vertebral artery are independent risk factors for isolated vertigo.Basilar artery skewing and degree of basilar artery stenosis may be the protective factors.

Objective To examine the effect of hydroxyethyl starch (HES 6%, 200/0.5) on reticuloendothelial system (RES) function in hemorrhagic shock. Methods Thirty 8 to 12-week-old Wistar rats weighing 250-350g were randomly divided into two groups: HES group ( n = 15) and control group ( n =15) . The animals were anesthetized with intraperitoneal 0.5% pentobarbital sodium 30mg ?kg-1 Bilateral common carotid arteries were exposed and cannulated for MAP monitoring and blood-letting. Blood was gradually removed until MAP dropped to 40mm Hg, which was maintained for 60min. Then same amount of HES (HES group) or Dextran (control group) was infused. The Kupffer cells were separated and purified before hemorrhagic shock (T0), at 12h (T1) 24h (T2) 48h (T3) and 72h (T4) after HES or DEX infusion, when the animals recovered from shock. Phagocytic activity of Kupffer cells (KC) was measured by counting the amount of Latex particles ingested by KC. Results At the same intervals (T1-4) there was no significant difference in phagocytic activity of KC between the two groups. There was no significant difference in phagocytic activity of KC between T0 (baseline) and T1-4 in both groups.Conclusions The phagocytic activity of Kupffer cells in not affected by removed of 20-30% blood volume which was replaced by same amount of HES.

OBJECTIVE: To investigate the absorption characteristics of dauricine in rat intestine. METHODS: In situ single-pass perfusion model was used and the concentrations of dauricine in perfusate were determined by HPLC. The effects of perfusion rates, intestinal segments and drug concentrations on the intestinal absorption of dauricine were studied. RESULTS: The absorption rate and absorption degree of dauricine increased with the perfusion rates(0.1, 0.2 and 0.4 mL · min-1)(P<0.05); the absorption rate constants of dauricine in duodenum, jejunum, ileum and colon were not significantly different(P>0.05); at high, middle and low concentrations, the drug absorption rate constants(Ka) were (2.36±0.0073) × 10-2, (3.73 ± 0.0052) × 10-2 and(5.62 ± 0.0136) × 10-2 min-1, respectively, the apparent permeation coefficients(P.,) were(2.02±0.0002) × 103, (3.10±0.0007) × 10-3 and (5.31±0.0010) × 10-3 cm · min-1, respectively, the absorption percentages(P%) were 8.66%, 10.17% and 19.06%, respectively, and the accumulate absorption amount and accumulate absorption percentages of different concentrations at different time were very low. CONCLUSION: The absorption degree of dauricine increases with perfusion rates; there is no specific absorption site in the whole rat intestinal tract; the absorption of dauricine is very poor and the active transport is involved in the absorption mechanism of dauricine.

This paper studied on breeding selenium-enriched yeast by protoplast mutagenesis. A strain which the content of selenium is the highest is selected from thirteen strains yeast. The optimum conditions to form protoplast are lysed by 1 g/100 mL lywallzyme for 120 min, the formation and regeneration being 95.2% and 21.8% respectively. By mutating breed a strain of A1 which the content of selenium is 821 mg/kg and the amount of dry cell of 0.84 g/100 mL is obtained.

ObjectiveTo assess the relationship between the location,quantity and leukodystrophy of cerebral infarction and vascular cognitive impairment ( VCI ),and to compare the differences of the severity and domains of cognitive impairment among the different types of cerebral infarction,which will provide the pathophysiological evidence to the mechanism for the development of VCI. MethodThe patients suffering from cerebral infarction or leukodystrophy were recruited from either the ward or clinic in Tianjin General Hospital from April 2009 to April 2010,then assessed the cognition,and classified into different groups according to the location,size,quantity,whether or not they have leukodystrophy and the severity.The Logistic regression analysis was taken with whether or not the patients have had developed to the VCI as the dependent variable,and with the location,size,quantity,whether or not they have leukodystrophy and the severity as the independent variables.The differences of the score of NIHSS,Bathel index and the level of cognitive impairment were compared among patients with different types of lesions.Moreover,the difference of the score of MoCA for each cognitive domain were compared among patients with different types of lesions.ResultsThere was a relationship between key position infarction in the subcortex and white leukodystrophy with VCI.The position infarction in the subcortex and white leukodystrophy ( grade Ⅱ and Ⅲ ) might be the independent risk factors for the VCI( OR =1.752,2.135,3.753; 95％ CI 1.533-3.821,1.541-6.787,1.432-6.821,all P ＜0.05).There were significant differences in the domains of excusive ability,attention,calculation,fluent language and orientation.The average scores of the domain of excusive ability in the subcortical group (3.40 ± 1.90) and the mix group (3.83 ± 1.27) were significantly lower than the cortical disease group(4.28 ± 0.89,t =0.050,0.857,both P ＜ 0.05 ).The average scores of the domains of attention,calculation,fluent and orientation in the mix group were significantly lower than the subcortical group and cortical disease group.ConclusionsThere is a significant association of the key infarction in the subcortex and leukodystrophy with VCI.The patients with both the subcortex infarction and leukodystrophy are susceptible to VCI.The development of VCI is depended on the position of infarction instead of the quantity and size of infarction.The development of VCI is not only related to the white matter disease but also related to the severity of the leukodystrophy.The data highlights the need to small vessel disease.The patients with subcortical lesions mainly impair the executive ability.The patients with mix lesions may have more extensive domains and more severe cognitive impairment.

Objective To investigate curative effect in children with bronchial asthma by two treatment methods. Methods 100 children with bronchial asthma,according to the different treatment were divided into treatment group 50 cases and control group(50 cases). The first seconds vital capacity(FEV1),peak expiratory flow (PEF) ,vital capacity 25% of the instantaneous velocity (V75), vital capacity 50% of the instantaneous velocity (V50) ,vital capacity 75% of the instantaneous velocity(V25) and their percentage the percentage of predicted value were observed. Results Total effective of 43 cases(86.0%) in treatment group after treatment 4 weeks were higher than that in control group of 28 cases (56. 5 %) (x~2 = 3. 987, P ＜ 0.05); The percentage of FEV1 and PEF in two groups after treatment 12 weeks were significantly higher than that before treatment(x~2 = 4. 01,4. 21,4. 31,4. 08, all P ＜ 0.05), but it between the two groups was not statistically significant (x~2 = 2. 31,2. 41, all P ＞ 0.05); The pulmonary function of V75 、V50、V25 in two groups after treatment 12 weeks reached projected value of more than 90% ;The pulmonary function of V75 、V50、V25 after treatment compared with those before treatment were improved significantly (x~2 =4.285,4.234,4.311,4.278,all P＜0.05). Conclusion The curative effect of bronchial asthma were confirmed in two methods,but treatment group were better than the control group.

Objective:To identify potentially pleiotropic genes for lean body mass ( LBM ) and age at menarche ( AAM).Methods:The discovery sample consisted of 1 692 unrelated female subjects of European ancestry.The replication sample consisted of 801 unrelated female subjects of Han Chinese ancestry.A total of 909,622 single nucleotide polymorphisms (SNPs) were genotyped in both samples with the Affymetrix genome-wide genotyping array SNP 6.0.Bivariate genome-wide association analyses were then performed to the appendicular LBM and AAM.Results: Two SNP rs1860547 and rs11030746 identified by the bivariate GWAS were significant at the genome-wide significance (GWS) level;their P-values were <0.05 after replications.In the upstream of rs1860547, two genes KCNA1 and KCNA5 were found to be important for both LBM and AAM.In the downstream of rs11030746, one gene KCNA4 was found.Univariate GWAS also identified both SNPs to be significant at the GWS level; their P-values were <0.05 after replications.In the upstream of rs1860547 , two genes KCNA1 and KCNA5 are found to be important for LBM.In the downstream of rs11030746 , one gene KCNA4 was found.Conclusion:KCNA1, KCNA4 and KCNA5 are likely to be pleiotropic genes closely related to both LBM and AAM in European females.
