Cone-bine CT(CBCT)images of 2 130 maxillary third molars were divided into 3 groups according to the impaction position. The relationship between the floor of maxillary sinus and the roots of maxillary third molar was analyzed and compared.In low,median and high impaction groups the probability of the root tip of maxillary third molar higher than the floor of maxillary sinus was 4.5%,10.3% and 14.6% respectively.

AIM: To investigate the effects of oral administration of Astragalus membranceus, mung bean and arsenolite on the toxic of the arsenolite induced rats and the possible mechanisms with metallothionein (MT). METHODS: All the rats were oral administration with arsenolite. The Astragalus membranceus and mung bean were compared with the cadmium chloride which induced MT synthesis. The contents of MT were determined by cadmium saturation method, the liver mRNA levels for MT 1, MT 2 were detected by RT PCR. The protective effects of renal and liver were observed by testing alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCR). RESULTS: The contents of MT were accorded with the mRNA expression of MT 1, MT 2. Arsenolite, Astragalus membranceus and mung bean could induce the synthesis of MT, but the contents of MT which arsenolite induced were trace. The contents of MT significantly increased after oral administration of Astragalus membranceus and mung bean, especially in the Astragalus membranceus group (P

The Chinese acupuncture doesn't only belong to China but rather to the world.The boom of overseas acupuncture education and scientific research as well as the satisfactory working environment compels us to reflect the Chinese traditional medicine education in our country.Especially in higher education specialty courses of acupuncture should not be subdivided;meanwhile,much attention should be paid to elementary education of western medicine.

Objective To develop a quality standard for Dongfengju oral liq ui d (DOL). Methods Atalantia buxjfolia, Radix Scrophulariae, Fructus Aurantii in DOL was identified by TLC. Results The obtained TLC spots of Atalantia buxj folia, Radix Scrophulariae, Fructus Aurantii in DOL occurred at the correspond ing positions compared to the controls. Conclusion The method is proved to be simple, sensitive, precise and reproducible and can be used for the quality con trol of DOL.

20/h. In the regression equationthat AHI was as the dependent, only volumetric change rate of velopharynx had statistic significance. CONCLUSION Middle-age and old women with OSAHS have obvious anatomy abnormalities which are the morphological foundation of the OSAHS. Higher compliance of upper airway plays an important role in the OSAHS pathogenesis in middle-age and old women.

Objective To evaluate the intracranial arterial collateral blood flow pathways and the changes of hemodynamics. Methods A total of 29 patients with unilateral internal carotid artery occlusion were selected. In these cases, their ophthalmic arteries(OA) and cerebral arteries were observed using transcranial color Doppler ultrasonography (TCCD), color Doppler energy imaging(CDE) and contrast-enhanced color Doppler ultrasonography. Collateral pathways through the ill-lateral OA, anterior and ill-lateral posterior communicating artery(ACoA and PCoA, respectively) were demonstrated by reversal of blood flow in the ipsilateral OA, reversal of blood flow in the ipsilateral A1 segment of the anterior cerebral artery(ACA) or decrease of blood flow velocity in ipsilateral middle cerebral arteries (MCA) during contralateral common carotid artery(CCA) compression and the increase of blood flow velocity in ipsilateral P1 segment of the posterior cerebral artery(PCA) during ipsilateral CCA compression, respectively. Results ①Among 29 cases, bilateral OA of 29 patients(100%) and bilateral MCA, ACA and PCA of 16 patients ( 55.2 %) could be visualized by TCCD and CDE. The other 13 patients( 44.8 %) can be seen clearly only after contrast-enhanced color Doppler ultrasonography. ② There were intracranial arterial collateral blood flow pathways of 29 patients(100%) through OA, 24 patients( 82.7 %) ACoA and 2 patients ( 6.8 %) PCoA, respectively. ③ The blood flow velocity was higher in ill-lateral OA than in contralateral OA, but PI and RI lower( P

Objective To study the extracranial and intracranial arterial hemodynamic changes before and after carotid artery stenting(CAS). Methods Thirty-eight patients with extracranial internal carotid arterial(EICA) stenosis were selected.Before and after CAS, the vessel diameter,the peak systolic velocity(PSV) in bilateral EICA and the PSV, pulsatility index(PI) in bilateral middle cerebral artery(MCA),ophthalmic artery(OA) were measured respectively by color Doppler flow imaging(CDFI) and transcranial color-coded duplex sonography(TCCD).Results Compared with pre-CAS,the diameter of ipsilateral EICA showed obviously increase post-CAS(P 0.05 ).The established collateral circulation were closed. Conclusions The extracranial and intracranial arterial hemodynamic data measured by CDFI and TCCD are valuable in evaluation of CAS.CAS is an effective and safe treatment for carotid stenosis,and the long time follow-up remains to be.
