Objective To explore the normal reference values of infant intelligence in Fagan test of infant Method Fagan test was carried out in 315 healthy infants aged 6.5～14.0 month in Shenyang,Tieling and Jinzhou in Liaoning province.Results Infants with cognitive exponent X≥54.6 might be considered to be normal in development,49.9

1.The sagittal and transverse diameters of 1,456 transverse foramina in 728cervical vertebrae were measured.The data are as follows:transverse diameter(mm) sagittal diameter (mm)Left Right Left RightMale(702 cases) 6.0?1.0 5.9?1.1 5.4?1.2 5.3?1.1Female(754 cases) 5.9?1.0 5.8?1.1 5.3?1.1 5.1?1.12.Among the 710 transverse foramina of 357 cervical vertebrae observed,mostof them are of the elliptical type.3.19.3% of double transverse foramen were found in 710 transverse foraminawhich were mostly encountered at the 6 th cervical vertebra.4.The mean value of the external diameter of the cervical part of the vertebralartery is 4?0.7mm.in 40 sides of specimens.5.63.1% of the vertebral artery in the 710 transverse foramina were foundmedial to its accompanying vein.6.According to the relationship between the sagittal(X_1)and transversediameter(X_2)of the transverse foramen and the diameter(Y)of the vertebralartery,a formula,(?)=1.859+0.172 X_1+0.24 X_2,of multiple regression was formulatedThus,the estimated diameter of the vertebral artery from the sagittal diameter X_1and transverse diameter X_2 of the transverse foramen could be obtained and it maybe helpful for clinical practice.7.In case of arthrosis,the vertebral artery could be compressed by the unco-vertebral joint which are found mostly at the level of the 4～5th cervicalvertebrae.

Objective:To optimize the clarification process of total flavonoids extract from Geum aleppicum with ZTC1+1-Ⅱtype clarifying agent. Methods:With the solid removal rate, retention rate of the total flavonoids and clearance rate of protein as the indi-ces, single factor tests were adopted to study the effects of extract concentration, amount of clarifying agent, reaction temperature and reaction time on the clarification results. Results:The optimal clarification process was as follows:the extract concentration was 0. 5 g ·ml-1 , the amount of clarifying agent was 4% component B and 2% component A, the reaction temperature was at 60℃, and the soaking time was 60 min. The retention rate of total flavonoids was 91. 32%, the clearance rate of protein was 35. 82%, and the solid removal rate was 8. 1%. Conclusion:ZTC1+1-Ⅱ type clarifying agent has good effect on the clarification of total flavonoids extract from Geum aleppicum with promising feasibility and stability.

Objective To identify the animal drug of Cervus elaphs and C. nippon from origin of deers. Methods To extract DNA from deer blood and hairy antler of 11 species of deers such as C. elaphus, C. nippon and so on, and to gain the mitochondrial 12S rRNA gene fragment using the general primers of L1091 and H1478. Based on the sequence multialinement of 11 species deers above gene fragments, designing the couples of special difference primers and identifying C. elaphs and C. nippon. Results 12S rRNA Gene fragments can distinguish different deers well. The couple of primers (EP-1/H1478 and EP-2/H1478) PCR can effectively identify C. elaphus and C. nippon. Conclusion Special primer PCR is suitable for the identification of valuable Chinese medicinal materials, such as C. elaphus and C. nippon.

OBJECTIVETo observe the clinical efficacy and safety on moderate and severe persistent allergic rhinitis treated with acupuncture.

METHODSSixty-six patients of moderate and severe persistent allergic rhinitis were randomized into an acupuncture group (34 cases) and a western medication group (32 cases). In the acupuncture, group, acupuncture was applied to Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20), Ganshu (BL 18) and Shenshu (BL 23) in the prone, retained for 20 min; then in the supine, at Baihui (GV 20), Yintang (GV 29), yingxiang (LI20) Taichong (LR 3) and Hegu (LI 4), retained for 20 min. Acupuncture was given once every two days, three times a week, continuously for 8 weeks. In the western medication group, cetirizine hydrochloride was taken orally, 10 mg each time, once every day, continuously for 8 weeks. Separately, before treatment, after the treatment of 1 and 2 months and in 1 month after treatment, the total nasal symptom score (TNSS), the scores in the emotion rating scale for Ganzangxiang of TCM (ERSG) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTS(1) For TNSS, the results after 1 and 2 months treatment and in 1 month after treatment were all, reduced as compare with that before treatment separately in the two groups (P < 0.05, P < 0.01) The result after 2 months treatment was lower than that after 1 month treatment in the acupuncture group (P < 0.05). In 1 month after treatment, the result in the acupuncture group was lower than that in the western medication group (P < 0.05). (2) For ERSG, the score after 2 months treatment was lower than that before treatment in the two groups (both P < 0.05). The score after 2 months treatment in the acupuncture group was lower than that in the western medication group (P < 0.05). (3) For RQLQ, the score after 1 month treatment was lower than that before treatment and the score after 2 months treatment was lower than that after 1 month treatment in the two groups (all P < 0.05). The score after 1 and 2 months treatment and in 1 month after treatment in the acupuncture group was lower than that in the western medication group separately (all P < 0.05). (4) The total effective rate was 91.2% (31/34) in the acupuncture group and was 90.6% (29/32) in the western medication group, without significant difference between the two groups (P > 0.05).

CONCLUSIONAcupuncture is the safe and effective intervention on moderate and severe persistent allergic rhinitis. Compared with the western medicine group, the efficacy in the acupuncture group presents much more advantageous at its durability.

Objective To evaluate the application value of X-ray,echocardiogram,pulmonary perfusion scintigraphy,EBCT,Magnetic resonance Pulmonary angiography in diagnosis of PTE.Methods Twenty-five consecutive patients clinically diagnosed of having PTE were examined from july 2003 through March 2004. Patients underwent X-ray chest plain film, echoeardiogram, electronic beam computed tomographie (EBCT)angiography,ventilation-perfusion (V-P)seintigraphy,Magnetic resonance Pulmonary angiography (MRPA)and puhnonary angiography according to a strict diagnostic protocol.Two of the independent readers reviewed the pulmonary angiography and record all of the lobe and segmental involved in PTE and compared with other image method.Results Pulmonary angiography:all of the patients success underwent the technique,the pulmonary artery branch with PTE was in 556 of 775 branches (71.7%). Chest radiography had hints of diagnosis in 12 of 25 patients.Nine patients diagnosed with echocardiogram. Right heart enlargement was in 21,and pulmonary hypertension in 18.V-P scintigraphy revealed 247 segmental involved with PTE of 500 (52.0% ),and the sensitivity was 64.66% compare with the pulmonary angiography.There were 523 pulmonary branches involved PTE with EBCT pulmonary angiograpy of 775 branches,and the sensitivity was 94.06%.MRPA: 8 of 10 patients succeed in the technique, 155 branches of 248 were detected with PTE(62.5% ),the sensitivity was 81.29%.Conclusions EBCT is a high sensitivity method in diagnosis of PTE.Chest radiography and echocardiogram are the first-line modality of PTE.V-P scintigrapby is the valid compensation in diagnosis subsegmental pulmonary artery with PTE when EBCT miss diagnosis.Gd-CE-MRPA may be the second-line modality in diagnosis of PTE.

In lieu of large samples of cases and/or controls with hundreds of markers spreading throughout the human genome, researchers started to notice the dramatic increase of genome-wide association study (GWAS) for complex disorders, in the last 5 years. This paper highlights the statistical challenges in such huge-scale genetic studies, and introduces the analytical strategies and steps for handling GWAS data. Such issues as quality control of data, population stratification, methods available to data analysis and results presentation, replication, as well as the limitations of GWAS studies and the challenges presenting for statistics, are addressed.
