Objective To investigate the change of serum transforming growth factor(TGF)-?1 and vascular endothelial growth facter( VEGF) in children with different types of primary nephrotic syndrome( PNS). Methods Children involved in the experiments were divided into simple type group, 16 cases; nephrit was type group, 16 cases, collecting blood sample in prednison - pretreated stage and in prednison- treated stage;control group, 14 cases. Monoclonal EUISA detected TGF-?1 and VEGF. Results Serum level of TGF-?1 and VKGF in active stage of simple type were higher than those of remission stage. The level in nephritis type was no signifi cant difference between prednison- treated stage and prednison - pretreated stage. The level in nephritis type was significantly higher than that in simple type. Conclusion Monitoring the dynamic change of serum TGF-?1 and VEGF can assess the effect of prednison treatment,and evaluate the prognosis of nephrotic syndrome.

OBJECTIVETo observe the clinical effect of integrative medicinal therapy in treating children Henoch-Schonlein purpura (HSP) and its preventive effect on complicated renal impairment.
METHODSOne hundred and twenty children with HSP were equally randomized into two groups, the treated group and the control group. Both were treated with conventional Western medical therapy, but Sanhuang Qingxue Yin (SQY, a Chinese herbal drug) was given additionally to the treated group. Besides, a group consisted of 30 healthy children was set up as a normal control. Changes of symptoms, physical signs, routine urine, plasma endothelin-1 (ET-1) and urinary levels of beta2-microglobulin (beta2-MG), albumin (ALB) and immunoglobulin G (IgG) before and after treatment were observed, and the recurrence was monitored.
RESULTSThe cure rate and the total effective rate in the treated group were 80.0% and 98.3%, while those in the control group were 61.7% and 88.3%, showing significant differences between groups (P < 0.05); the disappearance time of clinical symptoms was shorter in the treated group than in the control group, also showing a significant difference (P < 0.01); after 1-month treatment, levels of plasma ET-1, and urinary beta2-MG, ALB and IgG were improved in the treated group, reaching the levels opproximate to those in the normal control (P > 0.05), significant difference was shown as compared with those in the control group and with those before treatment respectively (P < 0.01, P < 0.05). The recurrent rate was 13.33% in the treated group and 30.0% in the control group, and they were statistically different (P < 0.05).
CONCLUSIONThe integrative medicinal therapy is good for treating HSP in children, it could not only obviously relieve clinical symptoms, shorten the illness course and reduce the recurrent rate, but also effectively prevent the occurrence of renal impairment.

OBJECTIVETo study the hepatoprotective effect of the extract of Terminala catappa leaves (TCE) and the possible mechanisms underlying its protection on acute liver injury induced by D-Galactosamine (D-GalN).
METHODIn vivo: D-GalN-induced liver injury model was used to evaluate the effect of TCE on the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in mice. Structure of liver was observed and liver mitochondrial swelling was measured following D-GalN injection without or with TCE. In vitro: D-GalN-induced primary cultured hepatocytes injury model was used to value the effect of TCE on cultured hepatocytes. Cell viability was measured by means of MTT assay, and the AST and superoxide dismutase (SOD) activities in supernatant of cultured cells were investigated also.
RESULTIn acute hepatic injury test, with oral pretreatment of TCE, remarkable rises in serum AST and ALT activities (2.95 fold and 3.35 fold) induced by D-GalN were obviously reversed and significant morphological changes were remarkably lessened. In addition, the decrease in sensitivity of mitochondrial swelling to the exotic Ca2+ stimulation induced by D-GalN was also prevented by TCE. In primary cultured hepatocytes of mice, it was found that incubation with TCE could prevent the decrease in cell viability in a dose-dependent manner. It was also found that both the increase in AST level (1.9 fold) and the decrease in SOD activity (48.0%) in supernatant of primary cultured hepatocytes induced by D-GalN could be inhibited by pretreatment of TCE.
CONCLUSIONTCE has hepatoprotective activity and the mechanisms underlying its protective effect may be related to its antioxidant activity and protection on both hepatocytes and liver mitochondria.

OBJECTIVETo study the clinical features of pediatric acquired immunodeficiency syndrome(AIDS).
METHODSThe epidemiological, clinical and laboratory data of 66 children with AIDS were retrospectively studied.
RESULTSOf the 66 patients, 46 (69.7%) were male and 20 (30.3%) were female, with a mean age of 8.7 years (ranged 2-16 years). The mean age at diagnosis was 7.7 years (ranged 2-15 years). Vertical transmission as the route of infection was documented in 48 cases (72.7%). Fourteen children (21.2%) were infected through blood or blood products. The route of infection could not be identified in 4 cases (6.1%). Body weight loss was noted in 43 cases (65.2%), anemia in 42 cases (63.7%), fever in 40 cases (60.6%), fatigue in 38 cases (57.6%), rash in 31 cases (47.0%), chronic cough in 28 cases (12.1%), chronic diarrhea in 24 cases (36.4%), CNS involvement in 16 cases (24.2%), oral thrush in 13 cases (19.7%), and hepatosplenomegaly in 12 cases (18.2%). Body height of 30 cases (45.4%) and body weight of 26 cases (39.4%) ranked the lower level. The immune system was severely suppressed in 59 cases (89.4%) and moderately suppressed in 7 cases (10.6%).
CONCLUSIONSVertical transmission remained the most common route of pediatric HIV infection. There were various clinical manifestations in children with AIDS. The immune systems of the majority of children with this disorder were severely suppressed.

Polycomb group (PcG) proteins are a family of epigenetic regulators responsible for the repression of genes in proliferation and differentiation of stem cells. PcG protein complex consists of two important epigenetic regulators: PRC1 (polycomb repressive complex 1) and PRC2 (polycomb repressive complex 2). In order to further understand the functions of PcG proteins in stem cell growth and differentiation, we review the PcG protein composition, PcG protein localization in the target gene, PcG protein recruitment, and the functions of PcG proteins in the development of stem cells.

This paper is to report the study of the metabolism of lidamycin in vitro including in plasma and microsomes to guide clinical therapy. Lidamycin was quantified by detecting its active ingredient using HPLC-MS/MS. The metabolic stability of lidamycin in rat, Beagle dog, monkey and human plasma and liver microsomes, and its inhibition to cytochrome P450 isoforms in human liver microsomes were studied. Results showed that lidamycin was metabolized in the four species of plasma, and the sequence of metabolic rates in plasma were in rat > in dog > in human > in monkey. But among the four species of liver microsomes, lidamycin was metabolized only in monkey liver microsomes. There was almost no inhibition to cytochrome P450 isoforms at the concentrations of between 0.0005 and 10 ng x mL(-1). Therefore, the property of lidamycin metabolism in human is similar with that in dog, and metabolism of other drugs would not be decreased by cytochrome P450 as used along with lidamycin in clinic.
