TPX2(targeting protein for Xklp2)is a microtubule-associated protein in a new family of vertebrate spindle pole components.TPX2 is diffusely distributed all over the nucleus during the cell cycle phases S and G_2 and play important roles in mitotic spindle formation.TPX2 over expression was found in a variety of malignant tumors,that are asssociated with the centrosome amplification,aneuploidy,cell transfor- mation and the biological behavior of tumor.Blocking the expression of TPX2 can inhibit the growth of tumor cells.TPX2 may serve as a new candidate target for tumor therapy.The study progress of its structure and function,expression levels in cell cycle,molecular mechanism etc.was reviewed.

Objective To explore the effect of Lactobacillussalivariuson the number of CD4+CD25+Foxp3+Treg cells and expression of transform?ing growth factorβ1(TGF?β1)in asthma Balb/c mice. Methods Thirty?two female Balb/c mice were randomly divided into four groups:the nor?mal control group,the asthma group,the Lactobacillus salivarius group,and the asthma combined Lactobacillussalivariusgroup. Acute asthma mod?el was established by the ovalbumin challenge method. After extraction of primary spleen cells,flow cytometry was used to test CD4+CD25+Foxp3+Treg/CD4+T ratio in spleen lymphocytes. The levels of IL?4,IFN?γand TGF?β1 in the spleen cell culture supernatant were measured by ELISA method. Results The level of Th2 cytokine(IL?4)in the spleen cell culture supernatant of the asthma group was significantly higher than that of the control group(P<0.05),however,the level of Th1 cytokine(IFN?γ)was significantly lower than that of the control group(P<0.05). The ex?pression level of Th2 cytokine(IL?4)in the Lactobacillussalivariusintervention group was significantly decreased compared with the asthma group, and the Th1 cytokine(IFN?γ)expression level was elevated compared with the asthma group(P<0.05). The level of TGF?β1 in the Lactobacillus salivarius intervention group was higher than in the asthma group(P<0.05). The proportion of CD4+CD25+Foxp3+Treg/CD4+T in spleen lympho?cytes in the asthma group was lower than that in the control group(P<0.05),and was higher in the Lactobacillus salivarius intervention group than in the asthma group(P<0.05). Conclusion CD4+CD25+Foxp3+Treg was associated with the pathogenesis of asthma. Lactobacillus salivarius could adjust Th1/Th2 imbalance and reduce asthma inflammation through up?regulation of CD4+CD25+Foxp3+Treg and TGF?β1 expression.

Objective To investigate the effect of combined Metformin and esomeprazole therapy on plasma levels of gastrin,blood glucose,glycosylated hemoglobin(HbA1c) and insulin in elderly patients with type 2 diabetes.Methods A randomized,double-blind,placebo-controlled study of 41 elderly patients with type 2 diabetes was conducted.Patients were randomly assigned into treatment group(combination therapy with Metformin 0.5 g,bid or tid and Esomeprazole 20 mg,qd,for 12 weeks)and placebo group(Metformin monotherapy 0.5 g,bid or tid,for 12 weeks).Fasting blood samples were taken from vein before and after treatment.Fasting serum levels of gastrin,glucose,HbA1c,insulin,lipids,liver and renal functions were compared between the two groups.The homeostasis model of assessment for insulin resistance index(HOMA-IR) and insulin secretion index (HOMA-β)were calculated,and complications were recorded.Results There were no significant differences in body mass index and waist circumference between the two groups.Serum gastrin level was slightly increased in the treatment group 12 weeks after treatment,but without statistically significance [(127.20±9.21)ng/L vs.(131.53±7.84)ng/L,P＞0.05],and serum gastrin level had no significant differences in the placebo group before and after treatment [(128.42±4.58)ng/L vs.(127.51±3.47)ng/L,P＞0.05].However,there were no significant differences in the changes of blood glucose,HbA1c,insulin,HOMA-β and HOMA-IR before versus after therapy,and between the two group(all P＞0.05).Conclusions Combined Metformin and insulin therapy cannot increase serum gastrin and insulin levels and has no significant effect on reducing blood glucose and HbA1c levels in elderly patients with type 2 diabetes.

ObjectiveTo investigate the incidence and risk factors of antibiotic-associated diarrhea (AAD) of pediatric patients with severe bacterial pneumonia.MethodsClinical data of 1086 pediatric patients with severe bacterial pneumonia from January 2010 through January 2014 were recruited. The incidence and risk factors of AAD were retrospectively analyzed. ResultsThe incidence of AAD in 1086 pediatric patients with severe bacterial pneumonia was 36.74%. The incidence of AAD in patients younger than 2 years old were higher than that in those older than 2 years, once or more times of mechanical venti-lation history were higher than that with no arrangements of this treatment, administering of combined antibiotics therapy were higher than that with single antibiotics, and the incidence of AAD due to amoxicillin/clavulanate, piperacillin/tazobactam, cefo- perazone/sulbactam in pediatric patients were 43.55%, 43.75%, and 45.03%, respectively. Three β-lactam/β-lactamase inhibitors above were risk factors of AAD through multivariate Logistic regression analysis.ConclusionThe high incidence of AAD in pediatric patients with severe bacterial pneumonia was associated with some risk factors, including younger than 2 years old, me-chanical ventilation, combined antibiotics therapy and administration of β-lactam/β-lactamase inhibitor (amoxicillin/clavulanate, piperacillin/tazobactam, cefoperazone/sulbactam).

Arbuscular mycorrhizal fungi can infect the roots of Cercidiphyllaceae and form arbuscular mycorrhizae.Infection rate is from 12% to 30%,but infection strength is weak.4 species of Acaulospora and 11 species of Glomus were isolated and identified,including Acaulospora tuberculata,A.spinosa,A.foveata,A.denticulate,Glomus geosporum,G.clarum,G.constrictum,G.monosporum,G.laroideum,G.versifome,G.microcarpum,G.mosseae,G.hoi,G.halonatum and G.reticulatum.Among them,G.cercidiphyllorum is advantage species.So AMF may be a potent resource of biology which can stimulate the growth of Panax notoginseng.

This study was aimed to observe the clinical effect of nerve root cervical spondylosis treatment by muscle meridian manipulation with small-angle sagittal localized rotational pulling of the neck . A total of 60 cases of nerve root cervical spondylosis were randomly divided into two groups , which are the treatment group (by muscle meridian manipulation with small-angle sagittal localized rotational pulling of the neck) and the control group ( by tendon-soothing manipulation ) . The results showed that there were significant differences ( P< 0 . 01 ) in the comparison of cure rate after treatment . The total efficiency of the treatment group was 93 . 33%, and the control group was 70 . 00%. The treatment group showed better clinical effect with significant difference ( P < 0 . 05 ) . It was concluded that the application of muscle meridian manipulation with small-angle sagittal localized rotational pulling of the neck is maneuverable and time-saving in the treatment of cervical spondylosis . It has a remarkable therapeutic effect and is suitable for clinical application .

Objective To explore the effects of behavioral inhibition system/activation system (BIS/BAS) and emotion regulations on depression of adolescents.Methods 800 adolescents from an university and a middle school were chosen by cluster random sampling,and were surveyed by BIS/BAS scale,Beck depression inventory(BDI),center for epidemiologic studies depression scale (CESD) and cognitive emotion regulation questionnaire (CERQ).The data were analyzed by pearson correlation,F test and multiple stepwise regression analysis.Results (1) BDI and CESD were correlated positively with BIS (r =0.39,0.41,P ＜ 0.01),self-blame,rumination,catastrophizing,blame others and perspective(r =0.19-0.50,P ＜ 0.05-0.01),and negatively with planning,reappraisal (r =-0.08-0.24,P＜0.05).(2)The scores of severe depression group were highest(15.45 ±2.57,P＜0.01) in BIS,lowest in BAS-drive(9.60 ±2.99,P＜0.01),and nonadaptive emotion regulations were used mostly,and adaptive emotion regulations were done leastly.(3) Catastrophizing,BIS,reappraisal,rumination,refocusing and self-blame explained 35％ of total variance,and catastrophizing and BIS explained the largest proportion,respectively 25％ and 4％.Conclusion BIS/BAS and emotion regulations may be important factors influencing non-clinical depression of adolescents.
