Henoch-Schonlein purpura(HSP)is the most common vasculitic disease affecting children,which is a multisystem immunoglobulin A mediated vasculitis with a self-limited course affecting the skin,joints,gastrointestinal tract and kidneys.Antiphospholipid syndrome(APS)is a systemic autoimmune disorder characterized by a combination of arterial or venous thrombosis and recurrent fetal loss,accompanied by elevated titers of antiphospholipid antibodies.Both HSP and APS are multisytem diseases and are thought to result from immunologically mediated processes.It was known that APS can associated with HSP,but the relationship between the 2 diseases is unclear.The literature on HSP associated with APS was reviewed and the possible mechanism was analyzed.

Objective To detect the apoptosis and the intensity of proliferation in different types of renal pathology in children with lupus nephritis (LN), analyzed the relationship between apoptosis and proliferation in LN. Methods Twenty - seven children (aged 7-16 years old, 21 type IV and 6 type V ) with biopsy- proven LN and nine as controls were included in the study. Apoptosis was detected by in situ nick- end labeling techniques (TUNEL) in renal biopsy samples. Immunohistochemistry was employed to detect the proliferating cells identified by proliferating cell nuclear antigen (PCNA) and detect the expressions of proteins of apoptosis associated gene PDCD5 and Caspase - 3 in these patients. Results 1. Compared to type V LN, the patients with type IV LN had more apoptolic cells,more PCNA positive cells and higher ratios of PCNA/apoptosis (P/A) in glomeruli. 2. There were no difference in expression of PDCD5 in glomeruli in type IV LN compared with those in type V LN. Numbers of apoptotic cells were observed in glomeruli. The expression of Caspase- 3 in type IV LN increased in glomeruli compared with that in type V LN. Conclusions The up- regulation of mechanism of apoptosis in type IV LN was less than that of type V LN. Caspase- 3 participated in the apoptosis of glomeruli of LN, but PDCD5 did not play a role during apoptosis of glomeruli of LN or the effect of PDCD5 promoting apoptosis was depressed.

Objective To analyze the correlative factors of prognosis of neonatal stress-induced ulcer bleeding.Methods Fifty-four cases of NICU admitted stress-induced ulcer bleeding newborns were divided into mild group and severe group according to bleeding endurance,transfusion requirement,and clinical turnover.Compared with gender,gestational age,birth weight,and score for neonatal acute physiology(SNAP) Ⅱ and score for neonatal acute physiologyⅡ perinatal extension(SNAP-PE) Ⅱ of two groups.Results Based on the output of SPSS statistical package,the SNAP Ⅱand SNAP-PE Ⅱ had a significant deviation between two subgroups((?~2=)15.207,10.311 all P

italic>Mycobacterium tuberculosis, responsible for tuberculosis (TB), remains a major health problem worldwide and is one of the infectious diseases causing increased morbidity and mortality worldwide. Biotin, namely vitamin H, is an important cofactor necessary for fatty acid biosynthesis, gluconeogenesis and amino acid metabolism in organisms including Mycobacterium tuberculosis. Due to its inability to ingestion biotin from outside, Mycobacterium tuberculosis can only obtain biotin through biotin biosynthesis. Different from the classical BioC-BioH, BioI-BioW and non-classical BioZ pathways, Mycobacterium tuberculosis synthesized biotin by "BioC-BioH(2)" pathway in the early stage. This review focuses on the unique biotin synthesis pathway of Mycobacterium tuberculosis and its key genes, especially the response of this pathway and biotin-dependent carboxylase to tuberculosis first-and second-line drugs, as well as inhibitors and natural products targeting biotin synthesis.

Objective To investigate the expression of FHIT,WWOX and MDR1 gene in nasopharyngeal carcinoma and FHIT and WWOX mechanism of inactivation.Methods Real-time PCR was used to test FHIT,WWOX and MDR1 gene′s mRNA expression in 89 nasopharyngeal carcinoma patients (experimental group) and 61 inflammatory patients (control group).Q-MSP was used to test the FHIT and WWOX promoter methylation status.Denatured polyacrylamide gel electrophoresis was used to test the LOH of FHIT and WWOX gene.Results (1)The three genes′ mRNA expression were different between experimental group and control group (P<0.05).After grouped according to the histological type and clinical stages,the expression of FHIT and WWOX mRNA between the patients with serious illness or poorly differentiated squamous cell carcinoma and mild cases or highly differentiated squamous cell carcinoma were significantly different in the experimental group,the difference is statistically significant (P<0.05)Meanwhile,the FHIT and WWOX mRNA expression had statistical association with the clinical stage and histological type(r=-0.731,P=0.000;r=-0.816,P=0.000;r=-0.626,P=0.000;r=-0.536,P=0.001).The MDR1 mRNA expression was different between poorly and highly differentiated squamous cell carcinoma (P=0.021),which was statistical associated with the histological type (r=-0.697,P<0.001).(2)The degrees of FHIT and WWOX promoter methylation in the experimental group was higher than those in the control group,the difference was statistically significant (P<0.05);Also,the expression of FHIT and WWOX mRNA were closely related to the degree of promoter methylation(r=-0.689,P=0.000;r=-0.594,P=0.000).(3) In the experimental group,there were 39 cases (43.8%) of LOH in the FHIT gene,and 42 cases (47.2%)of the WWOX genes were significantly higher than those in the control group (4.9% and 3.3%),the difference was statistically significant (P<0.05).The FHIT and WWOX gene mRNA were negatively correlated with the loss of heterozygosity(r=-0.239,P=0.049;r=-0.364,P=0.013).Conclusion Promoter methylation is the main reason for the down-regulation of FHIT gene and WWOX gene expression in nasopharyngeal carcinoma patients,which may be the main reason for the occurrence and development of nasopharyngeal carcinoma.The higher expression of MDR 1 mRNA is statistical association with the histological type.
