Objective:To investigate mRNA expression of cardiac related genes of NKX2.5,TBX5 and GATA4 in patients with tetralogy of fallot(TOF). Methods:A total of 10 TOF patients(TOF group)from 4 months to 8 years with the mean age of 3.5 years were recruited in our hospital from June to December 2005.The patients were diagnosed by typical clinical manifestation and cardiac color echocardiogram, the diagnosis was confirmed by cardiac surgery.6 non-congenital heart disease children were selected as Control group, and they were from 4 months to 9 years with the mean age of 3.8 years.The myocardial total RNA was extracted,the related cDNA was obtained by RT-PCR.The product cDNA was amplified with fluorescent quantitative PCR in order to compare the differences of NKX2.5,TBX5,GATA4 and GAPDH mRNA expression between TOF group and Control group. Results:NKX2.5 mRNA expression in TOF group was statistically decreased than that in Control group,while there were no statistical changes found in TBX5 and GATA4 mRNA expression between TOF group and Control group. Conclusion:The mRNA expression of NKX2.5,TBX5 and GATA4 were found in myocardium development.TOF was possibly related to decreased NKX2.5 mRNA expression.

The role of serotonergic system in vasovagal syncope (VVS) has been more concerned.Serotonin is a kind of neurotransmitter which is widely distributed in central nervous system.There are kinds of serotonergic receptors on postsynaptic membrane,among which 5-HT1A receptors participate in the mechanism of central blood pressure depression and promote the release of hormones such as prolactin and adrenocorticotrophic hormone.Acute administration of selective serotonin reuptake inhibitors (SSRIs) during head-up tilt test (HUT) blocks the reuptake of serotonin in the synapse space and thus increases stimulation of the serotonin receptors,which induces syncope episode.Long-term administration of SSRIs downregulates the postsynaptic serotonergic receptors,thus it weakens the reaction to the rapid change of serotonin concentration, which results in rapid depression of sympathic nerves and prevention of syncope episode.These demonstrate that central serotonergic system may participate in the pathogenesis of VVS and SSRIs are important for the diagnosis and treatment of VVS.

Objective　To investigate the interference of common methods in determination of creatinine. Methods　Standardized with Fuller′s earth, Jaffe′s method, enzymatic method (ultraviolet), enzymatic method (colour), enzymatic method (electrode) were compared and evaluated. Results　In eight interference materials, Jaffe′s method was positively affected by pyruvic acid (≥0.186 mmol/L), α-ketoglutaric acid(≥0.0615 g/L), ascorbic acid(≥0.82 mmol/L) and negatively affected by bilirubin(≥165.5 μmol/L). Enzymatic method (ultraviolet) was not interfered. Enzymatic method (color) was positively affected by creatine(≥0.21 mmol/L) and negatively interfered by dopamine(≥0.28 mmol/L). At last, enzymatic method (electrode) was positively interfered by creatine(≥0.62 mmol/L). Conclusion　Enzymatic method(ultraviolet) is the best in the above methods.

AIM:To study the relationship between the genetic polymorphism of CYP3A5 gene and the blood concentration/dose(C/D) ratio of cyclosporine combined with calcium channel blockers(CCBs) in renal transplant patients.METHODS:Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) analysis was applied to determine the genotype of CYP3A5 in 69 renal transplant patients.The blood concentration/dose(C/D) ratio of cyclosporine was compared in patients coadministrated of CCBs with different genetic polymorphism of CYP3A5.RESULTS:The cases of genotype of CYP3A51/1,CYP3A51/3 and CYP3A53/3 were 8,23 and 38,respectively.The mutation rate of CYP3A53 in renal transplant patients was 71.74%.The CsA C/D ratio of patients of CYP3A51/1 and CYP3A51/3 were 1.73 and 2.43 times higher than that in patients of CYP3A53/3.The CsA C/D ratio of patients(CYP3A51/1,CYP3A51/3) combined with CCBs had been obviously elevated(19.90?7.66 vs 36.01?8.18,34.33?7.87 vs 46.16?9.63 ng?mL-1 per mg?kg-1;P

Objective To observe the clinical efficacy of atorvastatin combined with neuroendocrine antagonist in the treatment of chronic heart failure.Methods 70 patients of Wenzhou Medical College Theorem Clinical College of Cardiology Department from March 2014 to March 2015 were randomly divided into observation group and control group of 35 cases in each group.The control group were given the neuroendocrine antagonist, observation group were given atorvastatin combined with neuroendocrine antagonist treatment. The changes of related indicators were recorded. Results The aminoterminal pro-brain natriuretic peptide (NT-ProBNP) and ejection fraction in observation group were [(1264.7 ±174.6)pg/mL, (0.58 ±0.07)], which were higher than those in control group [(2106.5 ±164.8)pg/mL,(0.49 ±0.08)](P<0.05).The total effective rate in observation group was 91.43%, which was higher than 71.43%in control group(P<0.05).Conclusion Atorvastatin joint neuroendocrine antagonist in treatment of chronic heart failure has clinical exact effect with no significant side effects.

The paper expounds the features of data in hospital information systems and analyzes current problems in domestic hospital information systems, particularly the problem of crisis handling with hospital data It also discusses the strategic data planning of hospital information systems, including organizational guarantee, systems development, technological pathways, and data models, The strategic data planning, which has been put into practice, has brought about good results.

Objective:To examine the expression of TRAF 6 in ovarian carcinomas ,discuss the relation between expression level and clinical characteristics of ovarian carcinomas and study the clinical significance .Methods: Specimens from 102 patients with ovarian carcinomas managed in our hospital between Augest 2001 and December 2009 were included in this study .Immunohistochemical staining was used to detect the expression of TRAF 6 in ovarian carcinomas and normal tissues .All the specimens were confirmed by pa-thology for ovarian carcinomas and normal tissues by HE staining .Then, the correlation between the expression and clinical characteristics of patients was analyzed .Furthermore ,survival analyses were performed according to the Kaplan-Meier method.Results:The positive expression rate of TRAF 6 in ovarian carcinomas and normal tissues was 68.6% and 20.5%, respectively.TRAF6 expression was significantly associated with tumor stage and distant metastasis ( P<0.05 ) .According to the survival analysis of 102 ovarian carcinomas patients ,cases in the TRAF6 low-expression group showed poorer overall survival rate when compared with low -expression group ( P<0.001 ) .Conclusion: These results indicate that the expression of TRAF 6 was closely related with in the progression of ovarian carcinomas and may have clinical utility in the prediction of prognosis of ovarian carcinomas .

Hypertension is a global problem,affecting both developed and developing nations. The mor-bidity of hypertension in children and adolescents has increased year by year in recent years. Hypertension in children can cause target organ damages(mainly renal,cardiovascular,central neurological,or optic fundal). In clinical practice,we need to find simple and easy methods for early recognition of target organ damages,thus se-rious consequences in adult hypertension may be prevented.

The reversed-phase high-performance chromatography was developed for determing the content of berberine, palmatine, emodin and chlorogenic acid in Xiaoerniuhuang Powder on ODS column. The powder samples extracted with methanol were determined separatly at their particular absorption points using external standard method.This method had advantages of perfect separatin, high sensitivity, good reproducibility and simple operation.
