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.

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.

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.

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 To compare the therapeutic efficacy between medicinal cupping and collateral-pricking bloodletting therapy in treating lumbar intervertebral disc herniation (LIDH) and non-specific low back pain.Method Sixty LIDH patients were randomized into treatment group 1 and control group 1, 30 cases in each group. Sixty non-specific low back pain patients were randomized into treatment group 2 and control group 2, 30 cases in each group. Treatment group 1 and 2 were intervened by medicinal cupping, while control group 1 and 2 were by collateral-pricking bloodletting. The Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were observed before and after intervention.Result The VAS and ODI scores were significantly changed after intervention in treatment group 1, treatment group 2, and control group 2 (P<0.05). The VAS score was significantly changed after intervention in control group 1 (P<0.05); the ODI score didn’t show significant change after intervention in control group 1 (P>0.05). After treatment, there was a significant difference in comparing the ODI score between control group 1 and control group 2 (P<0.05).Conclusion Medicinal cupping and collateral-pricking bloodletting are both effective in treating chronic low back pain, and medicinal cupping has its advantage in improving ODI compared to the bloodletting therapy.

This study was aimed to observe the effects ofFeng-Shi-Ning (FSN) capsule on the balance of IL-17+CD4+T (Th17) / Foxp3+CD4+CD25+regulatory T (Treg) cells in peripheral blood and the inflammatory media in synovial fluid of rats with rheumatoid arthritis (RA), in order to further study the mechanism of FSN capsule in RA treatment. The collagen-induced arthritisⅡ (CIA) was used in the RA rat model establishment. The balance of Th17 and Treg cells in peripheral blood was analyzed by the flow cytometry method for effects of FSN capsule treatment. The levels of TNF-α, IL-6, IL-17A, IL-4 and IL-10 in synovial fluid were measured by cytometric bead array (CBA) method. The effects of the normal rats, CIA model rats and the rats treated by tripterygium wilfordii polyglycoside tablet (TPT) were compared. The results showed that compared with the model group, the percentage of Th17 cells in both the FSN capsule group and high-dose CIA group were obviously decreased (P < 0.05). The percentage of Treg cells had the tendency of increasing in all treatment groups with no significant difference (P > 0.05). There was no significant difference on Th17 and Treg cells among each treatment group and TPT group (P > 0.05). Compared with the model group, the high-dose and middle dose FSN can obviously reduce the levels of TNF-α, IL-6 and IL-17A in synovial fluid of rats in each FSN group (P < 0.05). There was no obvious upregulating effect on IL-4 and IL-10 in synovial fluid of each FSN group (P > 0.05). Compared with the TPT group, there were no significant differences on IL-6, TNF-α, IL-17A, IL-4 and IL-10 in each treatment group (P > 0.05). It was concluded that FSN can obviously reduce the percentage of Th17, decrease the secretion of IL-6, TNF-α and IL-17A in synovial fluid. However, it had no obvious effects on the percentage of Treg cells, or the secretion of IL-4 and IL-10 in synovial fluid. The mechanism of FSN capsule in RA treatment may be through regulating Th17 cells, adjusting body immune imbalance, and inhibiting the excessive secretion of inflammatory media in synovial fluid.

Objective To explore the correlations between septic acute kidney injury (SAKI) and immune condition and provide the clinical basis of predictable diagnosis and treatment in patients with SAKI.Methods Patients diagnosed with sepsis admitted to department of emergency intensive care unit of Peking Union Medical College Hospital between January 1st,2013 and September 30th,2014 were retrospectively studied.A total of 91 patients with sepsis were included,and they were divided into secondary immune deficient (SID) group (n =46) or control group (n =45).According to the diagnostic criteria and stage of the guidelines of Kidney Disease:Improving Global Outcomes 2012 (KDIGO-AKI 2012),patients in each group were divided into non-SAKI group (n1 =16,n2 =23)、KDIGO-1 group (n1 =15,n2 =13)、KDIGO-2 group (n1 =11,n2 =1) or KDIGO-3 group (n1 =4,n2 =8).The morbidity of each stage and the renal index along with the progression of SAKI was also compared in patients with SAKI in two groups.Results While there was a significant difference in the morbidity of KDIGO-2 (23.9％ vs.2.2％,x2 =0.321,P =0.002) in patients with SAKI between immune deficient group and control group,the morbidity of KDIGO-1 and KDIGO-3 had no significant difference (KDIGO-1:32.6％ vs.29.8％,x2 =0.040,P =0.701;KDIGO-3:8.7％ vs.17.8％,x2 =-1.805,P =0.200).There was also no significant difference in the renal index (△Scr、△eGFR) and progression of SAKI (elapsed days from the diagnosis of sepsis to the occurance and most severe stage of SAKI) in patients with SAKI in two groups (P ＞ 0.05).Conclusion There was no significant difference of the severity of septic acute kidney injury in patients with and without secondary immune deficiency.Inflammatory mediators-induced kidney injury in the process of immune response may not be the main mechanism in SAKI.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.
