Objective To study the change of the eonnxin43 expression in the heart of diabetic mellitus rats. Methods STZ-in-dueed diabetic mellitus in rats were developed. The expression of connexin43 in the heart was detected by immunohistochemistry and image analysis, and the heart function was observed by electrophysiolograph and echocardiogram. Results During the course of diabetic mellitus, the expression of connexin43 in the heart of diabetic rats decreased respectively in the 12th week and 24th week (P<0.01). The values of dp/dtmax and + dp/dtmax in group DM in the 12th week and 24th week were lower than that in normal control group respectively (P<0.01), and the LVEF were also decreased (12w P<0.05,24w P<0.01). The analysis of correlation showed that the expression of con-nexin43 in heart were positively correlated with heart function (P<0.05) . Conclusion The expression of Connexin43 evidently de-creased in the hearts of diabetic rats and it is positively correlated with the heart function.

Objective To evaluate the effects of clinical pathway combined with transitional care implemented by specialty nurses on patients with coronary heart disease after PCI (percutaneous coronary intervention) therapy. Methods Totally 124 patients after PCI were divided into the experimental group and the control group with random digit table. Patients in the control group received routine education and follow- up during hospitalization and discharge period. The experimental group received clinical pathway combined with transitional care implemented by specialty nurses based on routine education. The level of patients′knowledge, attitude, practice and risk factors were compared between the two groups 6 and 12 months after discharge. Results There were 55 patients in each group completed the research ultimately. The Coronary Heart Disease Knowledge Questionnaire in the experimental group scored (57.61 ±8.77), (81.27±6.88) and (88.47±6.10),while the control group scored (59.71±7.32),(68.61±7.12) and (76.85±7.70), after repeated measurement analysis of variance, F=74.71, 14.52, P<0.01. The scores of General Self- Efficacy Scale (GSES) and Coronary Artery Disease Self- Efficacy Scale (CSMS) between two groups at three time points showed statistical significance, F=5.40, 14.52, P<0.05 or 0.01. The risk factors of coronary heart disease such as total cholesterol, triacylglycerol, hemoglobin A1c, body mass index, systolic pressure and diastolic pressure were statistically different between two groups except for high density lipoprotein cholesterol and low density lipoprotein cholesterol, F=5.82, 20.32, 4.14, 4.15, 4.99, 7.15, P<0.05 or 0.01. Conclusions Clinical pathway combined with transitional care implemented by specialty nurses can improve the knowledge-attitude- practice level of patients, help to control the risk factors of coronary heart disease. It is an effective heart rehabilitation model for patients after PCI.

Objective To investigate the effects of diclofenac sodium suppositories on emergence agitation after sevoflurane maintenance in children undergoing adenotonsilleetomy. Methods Forty-five patients selected for adenotonsillectomy were randomly divided into three groups (n=15). Patients in group 1 were given diclofenac sodium suppositories 12.5 mg right after intubation, those in group 2 were given diclofenac sodium suppositories 12.5 mg immediately after operation, while those in control group were not treated with diclofenac sodium suppositories before or after operation. The extubation time and time spent in post-anesthctic ICU (PACU) were recorded, the modified Aldrete score and pain score were assessed after entrance into PACU, and pediatric anesthesia emergence delirium (PAED) scale was administered 10, 20 and 30 rain after entrance into PACU. Results There was no significant difference in extubation time and time spent in PACU among three groups(P>0.05). Ten minutes after entrance into PACU, the PAED score of group 1 was significantly lower than those of group 2 and control group(P<0.05), while there was no significant difference between the latter two groups(P>0.05). Twenty and thirty minutes after entrance into PACU, the PAED scores of group 1 and group 2 were significantly lower than that of control group(P<0.05). There was no significant difference in the modified Aldrete score right after entrance into PACU among three groups. The pain scores of group 1 and group 2 were signifiantly lower than that of control group(P< 0.05). Conclusion Diclofenac sodium suppositories can decrease the incidence and severity of emergence agitation after sevoflurane maintenance in children undergoing adenotonsillectomy.

Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.

OBJECTIVETo investigate effects of paraquat on the mRNA expression of key elements of Notch signaling (Notch1, Jagged1 and DTX1) during differentiation process of human neural stem cells (hNSCs).

METHODShNSCs exposed to PQ at the concentrations 0.10, 1.00, 10.00 M. Cell proliferation ability was assessed using MTT assay and mRNA expressions of Notch1, Jagged1 and DTX1 were detected by Real-time RT-PCR at 2, 4, 8, 12 d of differentiation.

RESULTSCompared with control group, NOTCH1, JAG1 mRNA expression levels exposed to PQ at the concentration of 0.10 M significantly reduced at 2, 4, 8 d and significantly went up at 12d (P < 0.01). Compared with control group, NOTCH1, JAG1 and DTX1 mRNA expression levels exposed to PQ at the concentration of 10.00 M significantly reduced at 2, 8, 12 d (P < 0.01). PQ could down-regulate Notch1, Jagged1 and DTX1 mRNA expressions at the early stage of differentiation, then up-regulate Notch1 mRNA expression, and down-regulate Notch1, Jagged1 and DTX1 mRNA expressions at the end of differentiation.

CONCLUSIONNotch signaling pathway may be involved in differentiation of neural stem cell exposed to PQ.

Objective To investigate the expression and clinical significance of peripheral blood CD4~+, CD25~+ and CD4~+CD25~+ T subpopulations in patients with systemic lupus erythematosis.Methods The per- centage and fluorescence intensities of peripheral blood CD4~+,CD25~+ and CD4~+CD25~+ subpopulations from 34 SLE and 18 normal controls were measured with flow cytometry assay,then the correlation with clincal data was analyzed.The CD25~+ cells were defined as the CD25~(high) cells if their fluorescence intensity was higher than 10. Results The percentage of CD4~+CD25~+,CD4~+CD25~(high) T lymphocytes in active SLE patients[(4.80?1.21)% and (0.25?0.10)%]was lower than that in normal controls[(8.92?3.21)% and(0.44?0.22)% and non-active SLE patients(11.28?2.09)% and(0.59?0.34)%](P＜0.05).However,as for the CD25~+ cells in the CD4~+ T cells,there was no difference between SLE patients and normal control group.Peripheral blood CD4~+CD25~+,CD4~+CD25~(high) cells in SLE were reversely correlated with SLEDAI(r=-0.74,P=0.004 and r=-0.614,P=0.026),but not with others such as complements,ANA titers etc.Peripheral blood CD4~+ and CD25~+ lymphocytes in active SLE pa- tients were also lower than those in normal controls[(23?7)vs(34?7)and(7.4?1.8)vs(13.9?3.4),P＜0.05]. CD25 fluorescence intensities were higher in the SLE patients those in the normal controls,but CD4 fluores- cence intensities were not.Conclusion CD4~+CD25~+ may play a role in the pathogenesis of SLE.

Objective To describe the prevalence and relationship between physical activity (PA),depressive symptoms and school life satisfaction among middle school students in Bengbu,Anhui province.Methods A total number of 5268 boys and girls were analyzed from 4 middle schools.Depressive symptoms were assessed,using the Depression Self-rating Scale for Children,school life satisfaction via the School Life Satisfaction Rating Questionnaire.Self-reported PA and sedentary behaviors were also assessed.Descriptive statistics and logistic regression models were used.Results Adolescents self-reported rates of participating in sufficient moderate,vigorous and insufficient PA were 14.7％,36.0％ and 59.1％,respectively.The prevalence rates on depressive symptoms and school life dissatisfaction were 24.4％ and 25.9％.After adjusting on sedentary behaviors and other potential confounders,participants who had engaged in sufficient moderate and vigorous PA had odds ratios of 0.73 (0.60-0.89),0.68 (0.59-0.79) and 0.76 (0.63-0.92),0.70 (0.61-0.81) for likelihood of being depressive and school life dissatisfaction,compared to their counterparts who participating in insufficient moderate and vigorous PA.Insufficient PA was positively associated with depression and dissatisfaction of their school lives [OR (95％ CI):1.42(1.24-1.63) and 1.45 (1.27-1.66)].Conclusion High prevalence of insufficient PA was seen among adolescents and PA was closely related to the presence of depressive symptoms and school life dissatisfaction among middles school students.
