A questionnaire survey on awareness of child health management was conducted in 238 family members ( 236 were parents) of children aged 0 - 36 months; among whom 92 of children aged 0 to 6 months,85 of children aged 7 to 12 months,33 of children aged 13 to 18 months,16 of children aged 19 to 24 months and 12 of children aged 24 to 36 months.52.1％ of the surveyees had college education level.The awareness about medical examination in last half year in female subjects was higher than males ( P ＜ 0.05).There were no differences in other health management knowledge.The results showed that the average times of medical examination was 2.8 ± 1.9 in last half year; the age for supplement of meat in food was 7.4 ± 2.4 mouths; supplement of meat,animal liver and eggs was more than 7 time a week.The subjects with college education or above paid more attention to the children's growth,risk for rickets and anemia than other peoples.Pure breast feeding accounted for only 37.0％ (88/238).The study indicates that strengthening the knowledge and awareness is necessary to improve the children health management.

Objective To assess the value of multi-slice spiral CT angiography (MSCTA) in diagnosis of posterior nutcracker syndrome (NCS). Methods MSCTA of 15 patients clinically diagnosed as posterior NCS (patient group) and 50 subjects with normal renal vessels (control group) were retrospectively analyzed. The anatomy, course and relationship to the adjacent structure of left renal vein (LRV) and its branches were observed. The anteroposterior diameter (d1) and cross areas (s1) of the angle of control group and posterior abdominal artery (AA), the anteroposterior diameter (d2) and cross areas (s2) at the largest lumen near the renal hilar were measured and the ratio of s2/s1 and d2/ d1 were calculated.Results All LRVs posterior AA of patient group were compressed and narrowing with dilating apparently near the renal hilar. The difference of d2 was not significant (P＞0.05), but of other values were significant (P＜0.05).Conclusion MSCTA can show anatomy and three-dimentional trend clearly of LRV for posterior NCS, and evaluate the extent of narrow and dilating lumen accurately with cross areas measuring.

Objectives: To evaluate mice as experimental animal for Chlamydia pneumoniae, a common cause of acute respiratory infections in human.　Methods: Intranasal inoculation of Icr mice with C. Pneumoniae induced a prolonged course of lung infection, as demonstrated by persistence of lung pathology(60 days).　Results: Icr mice were susceptible to C. pneumoniae. Lung pathology was characterized by patchy interstitial pneumonitis with predominately neutrophil leukocyte infiltration in the early(7 days) and lymphocytes infiltration in the later stages(14 days later) of infection.　Conclusions:Icr mice were susceptible to C. pneumoniae and the mouse model is useful for the investigation of the pathogenesis of C. pneumoniae infection.

ObjectiveTo determine the effectiveness of endovascular embolization in patients with cryptogenic massive hemoptysis who were all long-term smokers.Methods Aortography and subclavian artery angiography were performed in 21long-term smokers with cryptogenicmassive hemoptysis.Transarterial embolization (TAE) was performed in patients with detectable pathologic systemic arteries.The angiographic findings were reviewed and the clinical and follow-up CT results were observed.ResultsThe pathologic systemic arteries were all bronchial arteries (BAs) and thirty-five arteries were involved.The angiography demonstrated peripheral hyperplasia in all BAs,with 24 pathologic BAs supplying the right lung and 25 supplying the upper lobes.In thirty-five BAs,24 showed hypertrophy and 11 were normal.TAE of the pathologic BAs was successfully performed and cessation of bleeding was achieved in all patients.During follow-up,one patient had episodic bloody sputum after embolization and no recurrence in all patients.The follow-up CTdemonstratednoadditionalabnormalitybesidespre-existingpulmonaryemphysema.Conclusion Cryptogenic massive hemoptysis in long-term smokers efficiently treated by endovascular embolization of the responsible bronchial artery.

This study is aimed to establish a high-performance liquid chromatography (HPLC) method for simultaneous determination of skimmin, scopolin and umbelliferone in Saussurea hieracioides. Samples were analyzed on a Wondasil C18-WR column (4.6 mm x 250 mm, 5 microm) with methanol (A) and water containing 0.1% phosphate (B) as mobile phases for gradient elution at a flow rate of 1.0 mL x min(-1). The detection wavelength and column temperature were set at 325 nm and 35 degrees C, respectively, and the sample size was 10 microL. The results showed that skimmin, scopolin and umbelliferone were simultaneously achieved within 40 min under the above conditions. A good linearity was observed in the range of 0.18-5.6 microg (r = 1.000 0), 0.060-1.8 microg (r = 0.999 9), 0.032-0.97 microg (r = 0.999 8) for skimmin, scopolin and umbelliferone, respectively, with the average recoveries of 99.16% (RSD = 0.41%), 100.3% (RSD = 0.79%), 102.2% (RSD = 0.87%). The method is simple, accurate and reproducible and can be used for the quality control of S. hieracioides.
