Objective To investigate the protective effects of sulforaphen (SFN) on focal cerebral ischemia/reperfusion injuy (IRI) in rats in order to explore the mechanisms.Methods Twenty-four male SD rats were randomly (random number) divided into Sham-operated group (A group,n =8),IRI group (B group,n =12),sulforaphen group (C group,n =8).SD rats were made to be transient focal cerebral IRI models.SFN 5 mg/kg was injected intraperitoneally to rats 15 minutes after IRI in C group,and rats of group A and group B received equal volume PBS instead.Infarct volume was measured by TTC staining and morphologic changes were observed with HE staining.Neuronal cell apoptosis index was detected by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-biotin nick end labeling (TUNEL) assay.Rats were sacrificed at 24 h after IRI.The protein levels of NF-κB p65 and iNOS were detected by using western bloting and the mRNA expressions of NF-κB p65 and iNOS were detected by using RT-PCR.Results Compared with the group B,infarct volume was significantly smaller in group C,the number of neuronal cell apoptosis in brain tissue were decreased significantly in group C [(96.34 ±3.72) vs.(124.65 ±3.85),P ＜ 0.01],the levels of NF-κB and iNOS in brain tissue of rats were decreased in the SFN group (P ＜ 0.01).SFN reduced neuronal cell apoptosis,injury,and infarct volume [(0.26 ± 0.018) vs.(0.43 ±0.031),P ＜0.01].The mRNA expression and protein level of NF-κBp65 were decreased in the group C.And the mRNA expression and protein level of induced nitric oxide synthase (iNOS) in IRI affected brain tissue were decreased in the group C [(0.67 ± 0.042) vs.(0.56 ± 0.032),P ＜ 0.01].Conclusions SFN might decrease the neuronal cell apoptosis caused by ischemia/repeffusion injury,and this protective effect is mediated by decreasing the level of NF-κB and iNOS.

Objective To investigate the effect of the stage-change model on the behavior changes of patients with non-insulin dependent diabetes mellitus (NIDDM). Methods A total of 169 cases NID-DM patients were randomly divided into the control group (84 cases )and the experimental group(85 cases ).The regular health education for the self behavior changes was carried out among patients in the control group,while besides the regular health education conducted in the control group,the stage- change model was additionally used in patients of the experimental group.By virtue of the self-design questionnaire,the surveys were performed on 2 groups respectively before the implementation,6 months and 12 months after the implementation.The behavior stages and behavior changes for the patients in 2 groups were compared. Results The end period of stage behavior and behavior change for patients in the experimental group were obviously better than those in the control group. Conclusions The stage-change model could accelerate the behavior change of patients with non-insulin dependent diabetes mellitus.

BACKGROUND:The preparation of recombinant human epidermal growth factor (rhEGF) and basic fibroblast growth factor (bFGF) has been clinical y used in the repair of ocular surface trauma. However, the concentration of these growth factors that achieve the maximal healing effect and the comparison of two kinds of growth factors on promoting wound healing are stil controversial.
OBJECTIVE:To investigate the effect of rhEGF and bFGF on the cloning of human corneal epithelial cells.
METHODS:The human corneal epithelial cells cultured in vitro were interfered with rhEGF and bFGF under different concentrations. The proliferation of human corneal epithelial cells was detected using MTT assay after 3, 5, 7 days of growth factors treatment. Plate clone formation assay was applied to observe the morphology of cellclone and analyze clone formation rate of human corneal epithelial cells.
RESULTS and CONCLUSION:MTT value shows that 10μg/L rhEGF and 10μg/L bFGF on day 5 were the most powerful concentration. The clone formation rate of human corneal epithelial cells after treated with 10μg/L rhEGF was higher than that with 10μg/L bFGF (P=0.02). The results confirmed that both rhEGF and bFGF could promote the proliferation and increase clone formation ability of human corneal epithelial cells. 10μg/L rhEGF for 5 days achieves the best effect on promoting clone formation of human corneal epithelium cells.

ObjectiveTo inyestigate the effect of miRNA-155 expression on the differentiations and functions of CD4 + T lymphocyte in patients with unstable angina pectoris. MethodsTwenty-one patients with unstable angina pectoris (UAP) were enrolled in this study, and another 18 patients with normal coronary arteries evidenced by angiography were assigned as control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression of miRNA-155 in CD4 + T lymphocyte of the peripheral blood. And the levels of IFN-γ and IL-4 in serum were determined by using enzyme-linked immunosorbent assay (ELISA). The CD4 + T lymphocyte were isolated from mononuclear cells prepared with Ficoll-Hypaque density-gradients centrifugation from human peripheral blood by magnetic cell sorting system. Then, the CD4 +T cells (2 × 106 cells/mL) were seeded in culture plates with 6 wells.The CD4 + T lymphocytes were divided into 3 groups in experiment: control group, miRNA-155 group, and miRNA-155 inhibitor group. The numbers of Th1 and Th2 cells were measured by flow cytometry analysis (FACS).The protein levels and expressions of IFN-γRα, T-bet, GATA-3 mRNA were measured by using western blotting and qRT-PCR, respectively. The levels of IFN-γ and IL-4 in culture supernatants of CD4 +T lymphocytes were detected by using ELISA. ResultsIn comparison with the control group, there was significant increase in the expression of miRNA-155 and serum level of IFN-γ in the UAP group (P ＜0. 01 ). There was a positive correlation between miRNA-155 and serum IFN-γ ( r =0. 842, P ＜ 0. 0l ).However, in vitro, the number of Th1, the protein level and expression of T-bet mRNA, and supernatant IFN-γ increased, and the protein level and expression of IFN-γRα protein decreased in miRNA-155 group in comparison with the control group (all P ＜0. 01 ). Interestingly, there were no significant differences in the number of Th2 cells, the expressions of GATA-3mRNA and IFN-γRα mRNA, GATA-3 protein and supernatant IL-4 between control group and miRNA-155 group ( all P ＞ 0. 05 ). And the miRNA-155 inhibitor could attenuate the effect of miRNA-155 effectively. ConclusionsThe miRNA-155 can promote differentiations and improve the function of Thl, playing an important role in the pathogenesis of unstable angina pectoris.

AIM: To study the protective effect and mechanism of panax notoginseng saponinsa(PNS) for dealing with rats with middle cerebral artery ischemia reperfusion(CI/RP). METHODS: To establish the rat middle cerebral artery ischemia/reperfusion model with suture occlusion technique and record the neurologic impairment evaluation score on the basis of Zea Longa method,measured the infarct volume,and the others were detected neuron apoptosis by TUNEL technology and endogenous brain-derived neurotropic factor(BDNF) expression by immunohistochemistry technology. RESULTS: The administration of PNS to rat decreased neurologic impairment,reduced infarct volume,inhibited the neuron apoptosis,and increased endogenous BDNF expression after 24 hours CI/RP. CONCLUSION: Increasing endogenous BDNF expression after CI/RP might be the mechanisms of PNS for achieving neuroprotections.

Objective To investigate the effect of early intervention with education combined with treatment on developing intelligence of preterm infants. Methods Ninety seven preterm infants were assigned into the intervention group(n=49)and control group(n=48):Those in the former group were managed with early intervention by education combined with medical treatment and those in the latter were given routine preventive health service.The two groups were compared in terms of body length and weight at months 6,9 and 12 as well as the developmental quotient(DQ)with developmental screening test(DST). Result The scores on DQ in the intervention group were all significantly higher than those of the control at the three time points(all P<0.01).Conclusion The early intervention with education combined with treatment is effective for the early development of intelligence of preterm infants.

Objective To observe the risk factors for portal vein thrombosis (PVT) in cirrhotic patients prior to receiving endoscopic treatment to prevent gastroesophageal varices rebleeding.Methods A retrospective analysis was conducted on cirrhotic patients admitted to Zhongshan Hospital,Fudan University from 2008 to 2013 for secondary prevention of gastroesophageal varices bleeding via endoscopic treatment.Relevant information and data were collected,followed by an univariate analysis and multiple Logistic regression analysis in attempt to identify potential factors affecting the formation of PVT.Results Totally 591 patients were enrolled in the present study and were classified as present-PVT group (n =122,20.64 ％) and absent-PVT group (n =469,79.36 ％).Univariate analysis showed that MELD score,hemoglobin,platelet count,total bilirubin,alanine aminotransferase,blood urea nitrogen,splenectomy ratio all achieved statistical significance between the two groups (P＜0.05).The multiple Logistic regression showed that MELD score,lowered blood urea nitrogen,elevated D-dimer and history of splenectomy were independent factors associated with the formation of PVT (P values were separately 0.016,0.026,0.014 and ＜0.001).Conclusions Cirrhotic patients should receive regular surveillance for MELD score,liver function,D-dimer and portal vein ultrasonography,especially in patients received with a previous history of splenectomy.

Objective To compare the sensitivity of HE,immunohistochemistry (IHC) and RT-PCR in detection of breast cancer metastases in axillary lymph nodes.Methods Twenty female patients with newly diagnosed and clinically node-negative breast cancers underwent modified radical mastectomy, including a complete axillary lymph node dissection. The ages of the patients ranged from 31 years to 65 years, and the diagnosis of breast cancer was approved by pathological finding. Two hundred and thirty-nine axillary lymph nodes were found in these 20 patients. Metastases in axillary lymph nodes were explored by HE, cytokeratin 19 IHC and RT-PCR for cytokeratin 19 respectively. Results Seven(2.9%) lymph nodes were found to have metastatic cancers by HE in 3 patients,all nodes were found in level Ⅰ. Metastatic cancers were found in 13 (5.4%) nodes by IHC in 7 patients,11 nodes in level Ⅰ and 2 nodes in level Ⅱ; and 52(21.8%) nodes were found to contain tumor cells by RT-PCR in 14 patients,30 nodes in level Ⅰ and 22 nodes in level Ⅱ. All of 7 histologically(HE) positive nodes were found to contain tumor cells by IHC and RT-PCR. Among 232 histologically(HE) negative nodes,6(2.6%) nodes were found to contain tumor cells by IHC,and 45(19.4%) nodes were found to contain tumor cells by RT-PCR, all 6 IHC positive nodes showed the expected 460-base pair products on gel electrophoresis ( P

Underlying both the angles of norm-referenced test and criterion-referenced test, the qualitative or(and)quantitative analysis and evaluation were made on the tests of 10 medical academic courses in recent 4 years in reliabil-ity and item quality. From the angle of norm-referenced test, 67.4 percent of the items had good quality, 60 percent ofthe tests could differentiate the classes and 12.5 percent of the papers could differentiate the individual person accord-ing to their reliability. However, from the angle of criterion-referenced test, approximately 90 percent of the items werequalified; 87.5% had high reliability to determine whether an examinee passes the test or not.[
