Objective To evaluate the relationship between cytotoxin-associated gene-A (CagA)seropositive of Helicobacter pylori (H .pylori )infection and risk of atherosclerotic cerebral infarction(ACI).Methods Related literatures were researched through literature retrieval ,literatures were obtained by uniformed criteria of inclusion and exclusion,and Meta analysis was performed with RevMan 4.2 software.Results A total of 10 literatures which met the inclusion criteria were retrieved,all were case-control study,case group included 907 studied subjects,and control group included 966 subjects;the included population were divided into Chinese subgroup and European Caucasian sub-group.Meta analysis of CagA seropositive of H .pylori infection and risk of ACI revealed that OR of the overall popula-tion,Chinese subgroup,and European Caucasian subgroup was 2.66(2.17-3.26),2.60(1.93-3.49),and 2.71(2.05-3.59)respectively;Meta analysis of CagA seronegative of H .pylori infection and risk of ACI revealed that OR of the overall population,Chinese subgroup,and European Caucasian subgroup was 0.74(0.49-1.10),0.81(0.45-1.48),and 0.64(0.37-1.09)respectively.The funnel plot and fail-safe number showed that there was no significant publication bias, the result was stable and reliable.Conclusion Chronic infection caused by CagA seropositive strains of H .pylori may be one of the risk factors of CAI,whether the eradication treatment of seropositive strains of H .pylori influences the process of atherosclerotic diseases like CAI needs to be further studied.

The human ovarian mucinous cystadenocarcinoma (hOMC) cells were co-cultured with antisense oligodeoxynucleotide (antisense ODN), nonsense ODN, and follicle-stimulating hormone (FSH) at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor (FSHR) on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups (P<0.05 or P<0.01), decreased distinctly in antisense ODN groups (P<0.05 or P<0.01), and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity (P<0.01). Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid-and high-dose antisense ODN groups (P<0.05 or P<0.01), while the number of cells in G(1)/G(0) phase was significantly decreased and that in S phase distinctly increased (P<0.01). There was no change in nonsense ODN groups (P>0.05). It was suggested that FSH may improve the development of hOMC cells. However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

Carotid atherosclerosis is an important pathogenesis of ischemic stroke.Inflammation plays a crucial role in the artery atherosclerotic genesis and development as well as its caused complications.Human CXC chemokine ligand 16 (CXCL16),as a novel chemokine,involves in the formation and development of atherosclerotic plaques.It may be associated with atherosclerotic stroke.

Applying cellular transplant methods in the treatment of peripheral nerve injury has become a new hot spot in tissue engineering and drawn much attention. Bone marrow stromal cells (BMSCs) grow fast and can be easily purified in vitro. Besides, they have the capability of differentiating into Schwann cells under specific conditions. For all the reasons above, BMSCs are considered good succedaneum of Schwann cells and new seed cells for tissue engineered peripheral nerve. In this review, the physiological functions and bionomics of Schwann cells and BMSCs are introduced, as well as various methods inducing BMSCs into nerve tissue cells and the foreground of the research.

Objective To construct the new diet intervention scheme of dyslipidemia of university teachers, discuss the effect of this plan on eating behavior change. Methods Choose two groups of college teachers in Harbin, who were hyperlipemia and had physical examinations from June to September, 2014. 44 teachers from one college were conducted the new dietary intervention as experimental group, 37 teachers from another college were the control group, used the usual method. Compared two groups before and after the intervention of dietary behavior and blood lipid. Results The experimental group′s dietary behaviors changed strongly after implement the new dietary intervention, the scores of DTS before the experiment (58.82 ± 18.47) points,3 months after the experiment (48.36 ± 14.25) points and 6 months after the experiment (44.18±14.92) points were statistically significant (F=21.308, P < 0.01). There was no statistically significant difference in control group (F = 1.129, P > 0.05), respectively (60.51 ± 16.91) points, (57.19 ± 16.35) points, (56.92 ± 21.35) points. After 6 months, the experimental group′s subjects of TC was (4.28±3.73) mmol/L, the control group was (6.23±1.04) mmol/L, the difference was statistically significant (t = 3.082, P < 0.05), there were no significant differences in TG, LDL-C and HDL-C of the two groups (P>0.05). Conclusions The new dietary guidance plan can effectively improve and maintain the dietary behavior in hyperlipidemia college teachers, and decrease the blood lipid level.

Objective This study was designed to evaluate the correlations between soluble E-selectin (sE-selectin) and intedeukin-8 (IL-8) levels and the condition and prognosis of severe pneumonia. Methods A total of 67 patients with pneumonia were identified at the intensive care unit and the Respiratory Department of Zibo Central Hospital between April 2007 and March 2008. The patients were divided into two groups according to the severity of pneumonia: severe (Group A, n = 35) and non-severe (Group B, n = 32). Group A was also subdivided into two groups of patiems: patients with Multiple Organ Dysfunction Syndrorae(MODS) (Group A_1, n = 13) and pa-tients with severe pneumonia alone (Croup A_2, n= 22). Thirty healthy people whose age and sex matched with the patients were enrolled as a control group (Group C). Patients with cancer, who had undergone surgery within the past 1 month, connective tissue disease or acute conplications of diabetes, for example, were excluded from the study. The serum levels of s-Eselectin and IL-8 were measured by EI.ISA, and correlations with Acute physiol-ogy and chronic Health Evaluation Ⅱ (APACHE-Ⅱ)score, Oxygenation index(PaO_2/FiO_2), percentage of poly-morphonuclear leukocyte (PMN)and high sensitive C-reactive protein (hs-CRP)levels were determined. The data were analyzed using t tests, one-way ANOVA, X~2 tests and linear correlation analysis using SAS 8.2 software. Results The sermn levels of sE-selectin and IL-8 in Croup A and Group B were significant higher than Group C (P < 0.05), and the levels in Group A were higher than those in Group B (P < 0.05). Furthermore, the levels of sE-selectin and IL-8 were higher in Group A_1 than in Group A_2(P < 0.001). The correlation analysis showed a positive correlation between the levels of sE-selectin and IL-8 in patients with pneumonia (r = 0.781,P < 0.01) ; and both were positively correhted with APACHE-Ⅱ score, PMN% and hs-CRP (P < 0.01), and nega-tively correlated with PaO_2/FiO_2 (P < 0.01).Conclusions sE-selectin and IL-8 levels are important indices for the assessment of the severity of pneumonia in tetras of the condition and prognosis.
