Objective To observe the effect of simvastatin on serum levels of matrix metalloproteinase-9(MMP-9) and tissue inhibitors of matrix metalloproteinase-1 (TIMP-1) in patients with acute coronary syndromes (ACS).Methods 74 patients with coronary heart disease were studied.Among them,there were 34 patients with stable angina pectoris(SAP) and 40 patients with ACS.At the same time 25 cases of age matched healthy individuals were selected as a control.The serum level of MMP-gand TIMP-1 were compared among all groups.Results There was a significant difference in serum level of MMP-9and TIMP-1 among SAP group,ACS group and control group.The serum level of MMP-9 and TIMP-1 were different after treatment.Conclusion Plaque disruption may be related to the increased serum level of MMP-9 and the decreased serum level of TIMP-1 .Simvastatin can decrease serum level of MMP-9 and increase serum level of TIMP-1 in patients with ACS,and it may have a beneficial effect on clinical treating of patients with ACS.

MicroRNA (miRNA)is a kind of endogenous non-coding protein single-chain small RNA consisted of 18~25 nucleotides.In recent years,researches found that miRNAs played important modulating role in occurrence and development of heart diseases.This article made an overview for that.

AIM:To establish a fingerprint method of analyzing Xuefu Zhuyu Capsule(Semen Persicae,Radix Angelicae sinensis,Fruclus Aurantii,Rhizoma Chuanxiong,etc.) by HPLC. METHODS: A HPLC in combination with PDA detector was applied with a HiQ C_(18)(4.6 mm?250 mm,5 ?m) column by gradient elution using methanol-1.0% acetic acid solution as the mobile phase.The flow rate was 0.5 mL/min and the detection wavelength was at 260 nm. RESULTS: Thitrty-six common peaks were obtained in the fingerprint of Xuefu Zhuyu Capsule with good separation,six of them were identified as adenosine,paeoniflorin,naringin,hesperidin,neohesperidin and ligustilide by comparing chromatogram with control compounds. CONCLUSION: The HPLC method with good precision and reproducibility can be used for the quality control of Xuefu Zhuyu Capsule.

SLE-like syndrome in (C57BL/6 x BALB/c) F1 mice can be induced by intravenous injection of lymphocytes from BALB/c parental mice. In these SLE-like mice levels of DNA antibody and anti—histone increased and there were immuno-complex mediated proteinuria, glomerulonephritis. 28 days later artesunate was given intraperitoneally to daily these mice. The results revealed that artesunate could significantly suppress the progression of disease activity,

Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

Objective To observe the effect of interferon combined with kenacort in the treatment of scars. Methods According to random number table,287 patients with scars were randomly divided into treatment group and control group.The treatment group(145 cases) was treated with injection of the mixture of interferon and kenacort. The control group(142 cases) was applied with contratubex.The effect and adverse reaction of the two groups were compared.Results The total effective rate of the treatment group was 95.86%,which was higher than 64.08% of the control group,the difference was statistically significant(χ2 =45.52,P<0.01).The incidence rate of adverse reaction of the two groups had no statistically significant difference(χ2 =1.25,P>0.05).Conclusion These find-ings may shed some light on the clinical application of combined injection therapy on scar treatment,given that the closed dynamic method of injecting interferon combined with kenacort significantly improved scar healing.

This paper proposes to re-understand characteristics of medical practice and quality management,and elaborates on the relationship between quality-based quality development and legal person concept,in line with the study and practice of medical service quality management.Moreover.it emphasizes the importance of legislation on quality and awareness of contemporary standard,together with an in-depth discussion on the shift from competence management to process-oriented management.In the end is a comment on typical case study.

Atypical hemolytic uremic syndrome(aHUS) has recently been shown to be a rare disease of genetic predisposition, including genes of complement factor H(CFH), membrane cofactor protein(MCP, CD46)and complement factor Ⅰ(CFI), which are complement regulatory genes. Genes mutation is about 50%,involving the three genes mutation, including nonsense mutation, missen mutation, silent mutation, splice mutation and insertion mutation. Autosomal dominant inheritance and autosomal recessive inheritance have been reported, however, for autosomal dominant inheritance, the three genes mutations are incomplete penetrance.

BACKGROUND:Oppositional defiant disorder(ODD) often occurs as a comorbid condition of attention deficit hyperactivity disorder(ADHD),characterized by defiant behaviors.ADHD children with ODD have more extensive impairments than those with ADHD alone. Some studies suggest that decreased serum 5 hydroxytryptamine(5 HT) level is related to aggressive behavior in ADHD, but no relevant report is available in China. OBJECTIVE:To investigate the clinical features of ADHD with ODD,and their relations with serum 5 HT. DESIGN:A randomized case controlled study taking the ADHD children with or without ODD as the subjects for study. SETTING:Mental Health Institute of the Second Xiangya Hospital. PARTICIPANTS:Sixty one ADHD children(53 boys and 8 girls) aged 7 to 14 years visiting the Children's Clinic of Mental Health Institute of Central South University from June 2002 to May 2003 were recruited and divided into two groups based on the symptomatic criteria of ODD recommended by the Diagnostic and Statistical Manual of Mental Disorder(DSM Ⅳ ):ADHD group(n=33,without ODD) and ADHD+ ODD group(n=28). INTERVENTIONS:The parents of the enrolled children(n=61) were asked to complete the Achenbach child behavior checklist (CBCL),and the teachers(n=31) completed the teacher's report form (TRF).Two milliliters of fasting venous blood was drawn from these children and the serum separated by centrifugation for quantification of 5 HT using external standard method,and whole blood 5 HT was analyzed by LD 10AD high performance liquid chromatography(HPLC). MAIN OUTCOME MEASURES:Scores of CBCL,TRF and Chinese Wechsler Intelligence Scale for Children(C WISC) and serum 5 HT levels. RESULTS:In the ADHD+ ODD group,the scores of CBCL and TRF for externalizing, aggressive behaviors and total scores for behavioral problems rated by the parents and teachers were significantly higher than those of the ADHD group(t=2.28 to 3.76,P< 0.05 to 0.01);the former group also had significantly higher scores of CBCL for anxiety/depression and internalizing(t=2.27 to 2.35,P< 0.05), but had significantly lower serum 5 HT level[(327.01± 164.84) μ g/L vs (451.11± 250.89) μ g/L](t=2.32,P< 0.05). CONCLUSION:Children with ADHD and comorbid ODD receive poorer ratings on all variables including externalizing and internalizing problems,adjustment variables and attention impairment. Increased aggressive behavior and lowered 5 HT level may be the biological markers of impulsive behavior in ADHD children with ODD.
