OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.
METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.
RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).
CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

To confirm the inactivating effect of chito-oligosaccharides on Tobacco mosaic virus (TMV) par ticles in vitro, the difference of TMV pathogenicity was evaluated according to the decrease of local lesion numbers after inoculating with TMV mixed with chito-oligosaccharides (DP3-10) in Nicotiana glutinosa, and the virion structural change was studied by transmission electron microscopy after mixed with chito-oligosaccharides. In the range of tested concentrations of chito-oligosaccharides (100-1000 microg /mL), the numbers of local lesions were strongly reduced with over 30% decrement, and the 88.4% reduction gained at the concentration of 600g /mL. It revealed that treatment with chito-oligosaccharide solution of 300-500 microg /mL directly broke TMV particles into tiny pieces of 50-150nm long, and that treatment with solutions of 600-1000 microg/mL caused virus particle agglomerated. The data presented here suggested that chito-oligosaccharides exerted strong inactivating effect on plant virus in vitro.

OBJECTIVETo study the anti-endotoxin activity and mechanism of F022 from Radix Isatidis.
METHODThe production of TNF-alpha and IL-6 of murine peritoneal macrophages stimulated by LPS was measured by ELISA. The temperature in rabbits was tested after i.v. administration of LPS. The lethality of BCG-primed mice was induced by LPS.
RESULTIf F022 was added to macrophages culture simultaneously with LPS or 1 h before addition of LPS, production of TNF-alpha and IL-6 by macrophages was remarkably inhibited in vitro. F022 inhibited the fever induced by LPS in rabbits and protected BCG-primed mice from LPS induced lethality if given before administration of LPS.
CONCLUSIONThe anti-endotoxin effect of F022 may inhibit LPS binding to its receptor, and it may be a LPS receptor antagonist.

OBJECTIVETo search for the possible relation between tortilcollis and partial chromosome 13q trisomy.
METHODSFluorescence in situ hybridization (FISH) technique combined with chromosome banding was performed to determine the karyotype of two patients with typical clinical features of partial 13q trisomy syndrome, then their manifestations were compared with those of the literatures published previously.
RESULTSThe two cases were partial trisomy of 13q14--> ter with a different second derivative chromosome, in spite of this difference, both of them had tortilcollis.
CONCLUSIONIt is suggested that a potential site for tortilcollis may locate on the long arm of chromosome 13. With reference to a report previously published, the more precise candidate related region may be 13q32--> qter.

OBJECTIVEChronic airway inflammation is associated with the polarization of TH2 cells in asthma. Prostaglandin D2 (PGD2) plays an important role in the polarization of TH2 cells. This study aimed to investigate the changes of PGD2 receptors (DP1/CRTH2) on T lymphocytes and their significance in asthma.
METHODSSeventy-two children with asthma were assigned to two groups: acute attack (n=42) and remission (n=30). Thirty-five healthy children were used as the control group. Plasma levels of TH2 cytokines IL-4 and IL-5, and TH1 cytokine INF-gamma were detected using ELISA. Radiological binding assay (RBA) was used to measure the contents of DP1/CRTH2 receptors on T cells in peripheral blood (PPB).
RESULTSThe total combining contents of DP and CRTH2 on T cells in PPB in the acute attack and the remission groups were significantly higher than those in the control group (p<0.01). There was no significant difference in the DP1 content among the three groups. Serum levels of IL-4 and IL-5 significantly increased (p<0.01), in contrast, serum levels of TH1 cytokine IFN-gamma were significantly reduced in the acute attack and the remission groups compared with those in the control group (p<0.01).
CONCLUSIONSThe total combining contents of DP and CRTH2 on T cells increased, serum levels of TH2 cytokines also increased, but serum levels of TH1 cytokine decreased significantly in the acute attack and the remission phases in children with asthma. This showed that a polarization of TH2 cells occurred in children with asthma and suggested that CRTH2 antagonism may be a new target for the treatment of asthma.
