Objective To identify the role of resistin in insulin resistance(IR) by endoplasmic reticulum(ER) stress in human umbilical vein endothelial cells ( HUVECs) and in rats.Methods HUVECs were cultured in vitro and disposed by resistin (R) or tauro ursodesoxycholic acid (tudca).Expressions of GRP78, P-akt and P-eNOS were determined using Western blotting.Thoracic aortic rings were made and their dilation function exposed to different concentrations of insulin was detected.Changes of vascular morphology were observed by HE staining.Results Results of Western blotting showed that expression of GRP78 was remarkably increased,but P-akt and P-eNOS were markedly decreased in R group.However, there was no difference in expressions of GRP78, P-akt and P-eNOS between tudca group and control group.The insulin induced vasodilation was decreased in R group and there was no difference between tudca group and control.Using HE staining, the R group showed significant medial thickening and proliferation of smooth muscle.Conclusion Resistin can induce insulin resistance in vascular endothelium cells by ER stress.
8.Phylogenetic Tree and Function Analysis of Inflorescence Meristem Identity Gene TFL1
China Biotechnology 2006;0(01):-
TFL1 homologs play important roles in maintaining vegetative growth and inflorescence meristem identity. The plants without the function of this gene usually are flowering earlier. Their normal inflorescence development is inhibited, the inflorescence meristem eventually acquired floral identity, which producing a terminal flower. Up to now, the TFL1 homologs have been isolated from 28 species of plants, including Arabidopsis, Snapdrogen and Tomato. The phylogenic tree of TFL1 proteins is almost accordance with the relative of those plants. The inflorescence identity gene TFL1 interacted with floral meristem identity genes LFY and AP1, so as to retard the transformation from inflorescence identity into floral identity. These meristem identity genes such as TFL1 and LFY can be applied in breeding of earl-flowering cultivars, there also have plenty of potentials in breeding fruit-free plantanus, popular or willows.

OBJECTIVE:
To evaluate the efficacy of sublingual immunotherapy with dermatophagoides farina drops on children with allergic rhinitis.
METHOD:
This was retrospective study analyzing the efficacy of dermatophaguides farinae drops SLIT in 110 patients (aged 4-14 years old) with house dust mites induced allergic rhinitis (without asthma). All the patients were divided into the SLIT group (n = 60) and drug group (n = 50). Patients in SLIT group received sublingual immunotherapy combined with symptomatic medication, and patients in drug group only received symptomatic medication. We recorded and evaluated the total nasal symptom scores (TNSS), total medication scores (TMS) and visual analogue scale (VAS) of the 2 groups at three time points, before the treatment, and the treatment for 1-year and 2-year.
RESULT:
After 1-year and 2-year treatment, compared with drug group, TMS, TNSS and VAS in SLIT group decreased significantly (P < 0.01). When compared with baseline, we got the similar result as compared with drug group. Besides, the TMS of drug group increased significantly after treatment (P < 0.01). And no significant difference was observed in TNSS and VAS. In addition, there was significant difference in the Proportion of patients withdrawing symptomatic medication in SLIT group and drug group (68.33%,16.00%, respectively; P < 0.01). There were 4 local adverse reactions occurred during the treatment and no serious adverse events occurred.
CONCLUSION
Sublingual immunotherapy with Dermatophagoides farinae drops showed significant clinical efficacy in children with allergic rhinitis comparing with pharmacotherapy.
