Aim To study the inhibitory effects and its mechanis ms of Garlic Polysaccharide (GP) on adriamycin(ADR)-induced cardiotoxicity in mic e.Mehtod ADR was injected intraperitoneally to induce myocardiu m injury model in mice. The activities of several serum and heart tissue enzymes were measured. With scanning electron microscope, the cardiac ultrastructural c hanges were examined.Results ADR (3 mg?kg -1 ip, qod?7) induced severe myocardial damages with the increasing activities of creatine kin ase (CK), lactate dehydrogenase (LDH), glutamic oxaloacetic transaminase (GOT) a nd inducible nitric oxide synthase (iNOS) (P

Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

Objective To assess the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist on prostate epithelial cells in vitro.Methods The expression of peroxisome proliferator-activated receptor γ(PPARγ) was studied by immunocytochemistry and immunofluorescence study.The RWPE-1 human prostate epithelial cell line was treated with PPARγ agonist rosiglitazone 100 μmol/L for 48 h.Analysis of apoptosis was performed by Caspase 3/7 activity assay.Mitochondria depolarization was measured by using the potential-sensitive color,JC-1.The expression of apoptosis-related proteins-Bax was investigated by immunohistochemistry.Results PPARγ mainly located in nucleus and perinucleus.RWPE-1 cell line treated with PPARγ agonist rosiglitazone showed higher Caspase 3/7 activity (10636±1032 RLU) than in control (5936±620 RLU),P<0.01 and significantly upregulated Bax level (8250±694 vs.6017±563)than in control group,P<0.01.In addition,mitochondrial membrane potential was depolarized in rosiglitazone treated cells.Conclusions PPARmay play important roles in the pathophysiology of BPH.The mechanism might be that PPARγ regulates cell apoptosis.It is suggested that the mitochondrial and Bax pathway might be involved in signaling PPARγ induced cell apoptosis.

Objective To investigate the serum levels of soluble CD23 ( sCD23 ) and thrombopeietin (TPO) in chronic lymphocytic leukemia (CLL) and their correlation with other prognostic factors. Methods The serum levels of sCD23 and TPO of 25 CLL patients were detected with enzyme linked immunosorbent assay. Flow cytometry was employed to determine the expression of CD38 and ZAP-70 protein. Results TPO level in CLL patients was significantly higher than that in normal controls 67.22 - 1881.77 ng/L and 70. 29 - 147. 98 ng/L respectively, P =0. 003. sCD23 level in CLL patients was significantly higher than that in normal controls 129. 80-405. 31 U/ml and 0. 65 -32. 99 U/ml respectively, P =0. 000. TPO level was significantly correlated with Binet stage and CD38 expression. Patients in stage B and C had higher level of TPO than those in stage A 140. 57 -457.48 ng/L and 121.92 - 163.83 ng/L respectively, P =0.014,while TPO level was higher in patients with higher CD38 expression than in patients lower CD38 expression 113.23- 199. 10 ng/L and 141.34 -454. 92 ng/L respectively, P = 0. 033. No significant correlation of sCD23 and TPO levels with ZAP-70 protein, sex, age, peripheral lymphocyte count and lactate dehydrogenase were observed. Conclusion Serum TPO level might be a prognostic factor in CLL.

ObjectiveTo investigate the effects of care bundles on the lactation of mothers of preterm infants.MethodsFrom January to June 2015, postpartum women who had preterm deliveries in First Maternity and Infant Hospital Affiliated to Tongji University with the neonates hospitalized in neonatal intensive care unit were enrolled in this study. They were randomly divided into intervention group (n=25) receiving bundle care (assist the mothers to determine lactation target; pump/express breastmilk within six hours after birth and keep a lactation diary to record the times and volume of pumped/expressed milk) and control group (n=22) given normal mammary guidance only. The time of the first pumped/expressed milk, the times for pumping/expressing milk a day, the total milk volume per day and rate of breastfeeding were compared between the two groups. Statistical analyses were conducted using two independent samplest-test,Chi-square test and nonparametric test.ResultsThe initial time of pumped/expressed milk of the intervention group was (6.1±3.4) h after delivery, significantly earlier than the control group [(10.7±9.3) h](t=-2.301,P=0.026). The times for pumping/expressing milk per day were significantly more in the intervention group than in the controlgroup on the 1st, 2nd and 3rd day after delivery [(4.2±2.2) vs (3.0±1.6); (6.2±1.1) vs (4.7±1.9); and (7.1±1.9) vs (5.9±1.9) times, respectively](t=2.083, 2.564 and 2.194, allP<0.05). From the second postpartum day, the milk volume of the intervention group was more than the control group [M(range) were 10.0(25.0) vs 2.0(5.0) ml] (Z=-2.879,P=0.005); and on the 21st day, the milk volume of the intervention mothers reached 800.0(295.0) ml, still higher than the control group [300.0(155.0) ml](Z=-3.179,P=0.001). The primarily breastfeeding (adding formula milk≤2 times a day) rate in the intervention group was significantly higher than in the control group on the 42nd postpartum day [68% (17/25) vs 41% (9/22),χ2=5.874,P=0.045].ConclusionThe care bundles on lactation can improve the lactation of the mothers of preterm infants.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective To explore the inhibitory effects of lobaplatin and cisplatin and their regulation of apoptosis-related genes in ovarian cancer cells in nude mice.Methods SKOV3 cells were implanted into nude mice.In monotherapy treatment study,the nude mice bearing human SKOV3 cells were randomly divided into control,lobaplatin,and cisplatin groups,with 7 mice in each group.The mice in each group were received corresponding treatment.The volume of tumor and the weight of nude mice were measured three times per week,respectively.Tumor inhibitory rate was calculated.The protein expressions of bax and bcl-2 were detected by flow cytometry.Results The growth inhibitory rate was 47.2% in lobaplatin group and 42.8% in cisplatin group,without significant difference between two groups (P > 0.05).The expression of bcl-2 was decreased but the bax was increased in lobaplatin and ciaplatin groups compared to the control group.Conclusions Lobaplatin can significantly inhibit the growth of ovarian cancer cells,induce apoptosis by down-regulation of bcl-2 and up-regulation of bax.
