OBJECTIVETo observe the effect of Ningdong Granule (NG) on serum levels of interleukin-12 (IL-12) and tumor necrosis factor-alpha (TNF-alpha) of children patients with Tourette's syndrome (TS).

METHODSTotally 90 TS children patients were randomly assigned to the NG group, the NG + Tiapride group (abbreviated as the combined treatment group), and the Tiapride group, 30 in each group. Besides,another 30 healthy children were recruited as the healthy control group. Patients in the NG group were treated with NG (consisting of all gastrodia rhizome, Codonopsis pilosula, Ophiopogon japonicus, white peony root, Rhinocerotidae, oyster, earthworm, licorice root, etc.), one dose daily, administered by dissolving it in boiled water, taken in two portions in the morning and in the evening respectively. Patients in the Tiapride group took Tiapride Tablet, 50 -100 mg each time, twice daily. The dosage was adjusted according to individual difference and changes of pathogenic conditions. The maximal dosage was 300 mg per day. Those in the combined treatment group were treated with equal dose of NG and Tiapride Tablet in combination. The treatment course was 3 months for all. Changes of pathogenic condition before and after treatment were assessed by Yale global tic severity scale (YGTSS). Serum levels of IL-12 and TNF-alpha were detected by enzyme-labeled immunosorbent assay (ELISA) before and after treatment.

RESULTS(1) The total effective rate of the NG group, the combined treatment group, and the Tiapride group was 79.3%, 83.3%, and 67.9%, respectively. It was the lowest in the Tiapride group (P < 0.05). It was significantly higher in the combined treatment group than in the NG group (P < 0.05). (2) The post-treatment YGTSS score was obviously lower in each group after treatment than before treatment (P < 0.05). The posttreatment YGTSS score was obviously lower in the NG group and the combined treatment group than in the Tiapride group (P < 0.05), but with no statistical difference between the fromer two groups (P > 0.05).(3) Compared with the healthy control group before treatment, serum levels of IL-12 and TNF-alpha (pg/mL) were 124.95 +/- 22.78 and 209.52 +/- 21.69 in the NG group, 126.14 +/- 25.65 and 208.97 +/- 22.46 in the combined treatment group, 123.00 +/- 24.26 and 205.10 +/- 26.16 in the Tiapride group, being higher than those in the healthy control group (64.56 +/- 27.59 and 78.13 +/- 33.42; P < 0.05). After treatment, serum levels of of IL-12 and TNF-alpha were 104.67 +/- 16.84 and 183.01 +/- 24.95 in the NG group, 109.04 +/- 16.81 and 179.87 +/- 23.45 in the combined treatment group, significantly lower than before treatment (P < 0.05). But there was no statistical difference in serum levels of IL-12 or TNF-alpha in the Tiapride group between before treatment (123.00 +/- 24.26 and 205.10 +/- 26.16) and after treatment (117.75 +/- 16.79 and 199.76 +/- 33.21; P > 0.05).

CONCLUSIONNG could modulate abnormal serum levels of IL-12 and TNF-alpha in TS children patients, which might be one of its pharmacodynamic mechanisms for treating TS.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

Objective To evaluate the association of islet autoantibodies [ glutamic acid decarboxylase antibody(GADA),protein tyrosine phosphatase antibody(IA-2A)and insulin autoantibodies(IAA)1 with HLA- DQ genotypes in the first-degree relatives of autoimmune type 1 diabetes mellitus.Methods This was a cross- sectional and case-control study.Three hundred and fifty-one first-degree relatives with normal glucose tolerance of patients with type 1 diabetes mellitus and 376 healthy controls were recruited and measured for GADA,IA-2A and IAA by radioligand assay,and 156 first-degree relatives of patients with autoimmune type 1 diabetes mellitus and 278 controls were typed for genetic polymorphisms of HLA-DQ with PCR sequencing-based typing method.Results (1)DQA1*03,DQBI*0303,*0401 alleles and DQA1 * 03-DQBI * 0303,DQA1 * 05-DQBI * 0201,DQA1 * 03-DQBI * 0401 haplotypes were significantly increased in the first-degree relatives of autoimmune type 1 diabetes mellitus(P

To study the enzyme kinetics of schizandrin metabolism in different gender in rat liver microsomes, liver microsomes were prepared from male or female rats. Schizandrin was incubated with rat liver microsomes. Schizandrin and its metabolites were isolated and identified by HPLC-UV method. Vmax, Km and Cl(int) of schizandrin in male and female rat liver microsomes were (21.88 +/- 2.30) and (0.61 +/- 0.07) micromol x L(-1) x min(-1) x mg(-1) (protein), (389.00 +/- 46.26) and (72.64 +/- 13.61) micromol x L(-1), (0.0563 +/- 0.0007) and (0.0084 +/- 0.0008) min x mg(-1) (protein), respectively. The major metabolites of schizandrin in female and male rat liver microsomes were 7,8-dihydroxy-schizandrin (M1) and 7, 8-dihydroxy-2-demethyl schizandrin (M2b), respectively. Ketoconazole, quinidine, and orphenadrine had different level effects on schizandrin metabolism in both male and female rat liver microsomes, and cimetidine still had some inhibitory effect in male liver microsomes. CYP3A and CYP2C11 may be the main P450 enzymes in schizandrin metabolism and their difference in rat liver microsomes may be the main reason for the sex difference of metabolic enzyme kinetics and metabolites of schizandrin in rats.

OBJECTIVETo study the expression and distribution of KDR, VEGF and CD34 in yolk sac and liver of human embryo at different development stage.

METHODSYolk sacs and livers of 15 human embryos were analyzed by the immunohistochemical SP kits for the expression of KDR, VEGF and CD34.

RESULTSKDR, VEGF and CD34 were all expressed in yolk sacs and livers of the embryos. In the intermediate liver group, the grey value of KDR and VEGF were 103.8 +/- 6.1 and 96.4 +/- 6.3, respectively, stronger than that in the late liver group which were 90.4 +/- 6.0 and 87.4 +/- 6.3, respectively (P < 0.05). A positive correlation between the levels of KDR and VEGF was observed (P < 0.05).

CONCLUSIONThe expression of KDR and CD34 in yolk sac and liver of embryo suggests the presence of hemangioblast in these organs. Interaction of KDR and VEGF might relate to survival, proliferation, migration and differentiation of hemangioblasts.
