Objective:To select the differentially expressed vascular smooth muscle cell(VSMC) apoptosis gene induced by icariin,glucose regulated protein 78(GRP78),to observe the expression of GRP78 in atherosclerosis tissue and to the elucidate the mechanism of anti-atherosclerosis of icariin.Methods:The model was established by using halfcystine in viro.The vascular smooth muscle cell was incubated with various concentrations of icariin for 48 hours.The apoptosis was detected by TUNEL assay.GRP78 gene was amplificated by PCR,recombinant plasmid were constructed,transfected into E.coli,positive clonings were selected and conf irmed by restriction endonucleas analysis,and sequence-ed.Tissue situ hybridization was used to observe the GRP78 expression in atherosclerosis tissue.Results:Icariin promoted obviously vascular smooth muscle cell apoptosis.Furthermore,the fragment,648bp,was similar to the gene of GRP78 from VSMC,and the expression level was signif icantly higher in high cholesterol group than in control nroup.Conclusions:The GRP78 plays a key role in inducing atherosclerotic lesions.The mechanism of anti-atherosclerosis of icariin might be partly due to promoting apoptosis of vascular smooth muscle cell.

Foreign bodies in the paranasal sinuses are rare. Foreign bodies in the ethmoid sinus are easily misdiagnosed as tumor. There is no typical display in CT and MRI tests. The described case showed the misdiagnosis of an ethmoid foreign body as tumour on the basis of CT and MRI results. It should be emphasised that the tumour diagnosis should be based on further physical and histopathological examinations and not only on the results of CT and MRI tests.

OBJECTIVE: To explore the olfactory abilities in patients with allergic rhinitis (AR), analyze the correlation between olfactory bulb (OB) volume with depth of olfactory sulcus (OS) and olfactory function in patients with AR. METHOD: One hundred patients with AR were compared with one hundred controls in terms of olfactory function T&T testing, OB volume and depth of OS assessed with magnetic resonance imaging (MRI). T&T testing and MRI were done after a year in 100 AR patients,the results were compared with the initial results. RESULT: The OB volume in AR patients was (29.53±3.95) mm3 on the left, (29.67±14.21)mm3 on the right, (29.61±4.05) mm3 on average; The OB volume in controls was (48.93±6.73)mm3 on the left side, (48.81±7.43)mm3 on the right side, (48.85±7.11)mm3 on average; The OB volume in AR patients was less then the control group(t= 6.321, 6.141, 6.221, P<0.01). The OS depth had no statistical difference between AR patients and controls (t=1.032, 0.972, 0.991, P>0.05). Olfactory discriminate threshold was negatively correlated with OB volume in AR patients (r=-0.46, P<0.05); and it was no correlated with depth of OS (r=-0.012,P>0.05). Among 100 followed-up AR patients, 43 showed increased in OB volume and olfactory function after a year, but there was no statistical difference (t= 0. 811,0. 843, 0.826, P>0.05; Z=1.911, P>0.05) ,and the other 57 showed no significant changes of OB volume and olfactory function. CONCLUSION In AR patients, the OB volume and olfactory function decreased, but the depth of OS had no significant changes. The OB volume is correlated with olfactory function, while the depth of OS is no correlated with olfactory function. Conservative treatment had some clinical significance on the recovery of olfactory function in patients with AR.
