BACKGROUND: Excessive nitric oxide (NO) release can cause the occurrence and development of brain injury and senile dementia due to the apoptosis induction role of NO at high concentration to nerve cells. Therefore one strategy to prevent and treat senile dementia is inhibiting the apoptosis induced by NO.OBJECTIVE: To observe whether acidic peptide will inhibit the neuron apoptosis caused by NO. DESIGN: An cell and molecule observation experiment by comparisons. SETTING: Department of Biochemistry and Molecular Biology of Basic Medical College in Zhengzhou University and the Second Laboratory of Biological Active Peptide Institute in Zhengzhou University. MATERTALS: The experiment was performed between May 2003 and May 2005, in the Second Laboratory of Biological Active Peptide Institute in Zhengzhou University and the cell culture room of Department of Biochemistry and Molecular Biology of Basic Medical College in Zhengzhou University. The newborn SD male rats within 24 hours after birth were provided by the Animal Center of Henan Province (410117).METHODS: On day 11 of primary cultures, hippocampus neurons of the newborn SD rats were pretreated with different dosages of acidic peptide for six hours. Sodium nitroprusside (SNP) of 50 μmol/L final concentration was added to the cells which were incubated for another 24 hours. Cells were collected and adopted in this experiment of five different groups, namely normal control group, group treated with SNP, group of SNP plus 0.037 5 mg/mL acidic peptide, group of SNP plus 0.075 mg/mL acidic peptide, group of SNP plus 0.15 mg/mL acidic peptide. The cell's survival rate wasmeasure by methyl thiazolyl (MTT) method; The neurofilament protein was stained with the method of immunohisto chemistry. The shape of apoptosis was display with acridine orange fluorescent stain. Then DNA ladder zone of apoptosis cells was analyzed with the method of agarose gel electrophoresis. Western Blot and absorbance scan were used to determine the expression level of Bcl-2 protein and Bax protein.MAIN OUTCOME MEASURES: ①Experimental result of cell survival rate with MTT method;②Observation results of nuclear type of apoptosis; ③DNA electrophoresis analysis of apoptosis; ④Western Blot analysis results of Bcl-2 protein and Bax protein.RESULTS: ①Neuron survival rate was 58.9％ for group treated with SNP, 70.0％ for group of SNP plus 0.037 mg/mL acidic peptide, 72.8％ for group of SNP plus 0.075 mg/mL acidic peptide, and 75.3％ for group of SNP plus 0.15 mg/mL acidic peptide. ②Observation results of nuclear type of apoptosis: Significant characteristics of apoptosis were seen in group treated with SNP. The nucleus of hippocampus neuron treated with different concentrations of acidic peptide plus SNP was similar to that of normal control group in morphology. ③The results of DNA electrophoresis analysis of apoptosis: Only the neuron DNA of group treated with SNP showed clear characteristic DNA ladder zone of apoptosis on agarose gel electrophoresis. ④Analysis results of Bcl-2 protein and Bax protein with Western Blot and absorbance scan: The expression level of Bcl-2 protein in SNP treated group was decreased while that of Bcl-2 protein was increased. Bcl2 protein levels in acidic peptide plus SNP group were increased and Bax protein levels were decreased gradually with the increasing concentrations of acidic peptide compared with SNP treated group. CONCLUSION: Acidic peptide can inhibit neuron apoptosis, increase expression level of neuron Bcl-2 protein and decrease expression level of neuron Bax protein.

Objective To investigate the clinical manifestation and management of acute cholangitis severe type (ACST) with different typos of obstruction. Methods From January 1997 to December 2006, 164 consecutive patients with ACST had been admitted to Chengdu First People's Hospital. All patients were divided into extrahepatic type group (n=122), intrahepatic type group (n=18) and mixed type group (n=24) accord-ing to the types of obstruction. Clinical manifestation and therapeutic outcome of the 3 groups were analyzed using chi-square test, continuity correction test or Fisher exact test. Results There was no significant difference in clinical manifestation between patients with extrahepatic type and those with mixed type (P>0.05). The incidence of jaundice and abdominal pain in patients with intrahepatic type is significantly lower than those with extrahepatic type (P<0.05). The incidences of distention in consciousness and response to initial medical treat-ment were higher than those with extrahepatic type (P<0.05). The total mortality rate was 9.8% (16/164). Of all patients, 123 received open surgery. There was no significant difference in morbidity and mortality in patients with intrahepatic type and mixed type (χ~2=0.172,0.789; 1.769, 1.948, P>0.05). In emergency operation, the incidence of biliary high pressure and postoperative vital sign improvement rates were significant higher in patients with extrahepatic type than the other 2 types (P<0.05). The morbidity and mortality of patients who received emergency operation were higher than non-emergency operation (P<0.05). Conclusions The clinical manifestation of ACST is different between intrahepatic obstructive type and the other 2 types. There is no signi-ficant difference in morbidity and mortality among the 3 types of obstruction. The morbidity and mortality are high in patients who received emergency operation. Proper management of surgical timing is helpful in decreasing the morbidity and motality of ACST.

Objective To explore the signal transduction mechanism of inhibitor kappa B kinase α( IKKα) , one of the catalytic subunits of IKK complex , for regulating p53 transactivation in the cellular ultraviolet radiation ( UVB) repsonse. Methods The transactivation of p53 was determined by dual-luciferase reporter gene analysis system while the expression and activation of IKKα, IKKβ, p53 and p38K was detected by Western blotting assay .Results UVB exposure induced activation and transactivation of p 53 in the wild type mouse fibroblasts ,but the effect was blocked by IKKa deficiency and recovered by reconstitution of IKKαexpression.Under the same conditions , IKKαregulated p38K activation, while inhibi-ting p38K activation down-regulated p53 transactivation under UVB exposure .Conclusion IKKαregulates UVB-induced phosphorylation and activation of p 53 in a p38K-dependent manner .
