In recent years,the incidence of allergic diseases is rising.The mild symptoms in allergic diseases are partial performance,but the severe symptoms in allergic diseases can induce anaphylactic shock and even death.With the unclear pathogenesis,there is lack of the effective treatment.Early detection and control of risk factors that cause allergic disease may be helpful in reducing the incidence of allergic disease.This review describes recent progress in the study of epidemiology, risk factors of allergic diseases, hypotheses of mechanism and the direction of future researches in risk factors of allergic diseases.

Objective To develop a qualitative and quantitative simultaneous determination of multiple bioactive constituents in total alkaloid in Sophora alopecuroides (TASA). Methods In the experiment, a new and simple HPLC-DAD method for the simultaneous determination of multiple constituents in TASA was developed. The separation was performed on a Kromasil C,8 column (250mmx4.6mm,5.0pm) eluted with 0.02 mol/L potassium dihydrogen phosphate (adjusted pH 4.3 using 1% glacial acetic acid) and acetonitrile (75:25) at a flow-rate of 0.7 mUmin. The detection wavelength was set at 210 nn. Results Five constituents (sophoridine, matrine, oxymatnne, aloperme, and lehmamune) were simultaneously analyzed in this study. Four of them were identified and determinated by the developed method. The calibration curves exhibited linear regressions (r~2>0.9995). The injection precision, the intra-day precision, and the ana hsis repeatability were validated with the RSD values less than 5.0%. The mean recoveries of the four constituents were ranged from 98.62% to 100.20%, and the RSD values were all less than 3.37%. Conclusion This method is convenient, fast, accurate, and is applicable to analyze the multi-constituents in TASA.

BACKGROUND: Intra-oral, extra-oral, and combination of intraoral and extra-oral incisions often use in mandibular angle contouring surgery. Minimally invasive incision at auriculocephalic sulcus in mandibular angle osteotomy is a new approach, but its report is rare. OBJECTIVE: To observe the anatomical structure of the mandibular angle and its related blood vessels and nerves, and to provide the anatomical basis for the minimally invasive incision at auriculocephalic sulcus in mandibular angle osteotomy. DESIGN, TIME AND SETTING: A single sample observational experiment was performed at Department of Anatomy in the Second Military Medical University from February to May in 2008. MATERIALS: A total of 15 adult skull specimens (30 laterals), including 11 female and 4 male, and 15 adult mandible (30 laterals) were used in the experiment. METHODS: Anatomical study was performed on 30 laterals of 15 skull specimens, observing distributions and arrangement of blood vessels and nerves as well as their position relation with mandibular angle. After sawing the mandible bones along mark lines, the distances from the mental foramen, mandibular foramen, and each section of mandibular canal to the edge, internal wall and external wall of the mandible bone were measured. The results were expressed as Mean?SD. MAIN OUTCOME MEASURES: The anatomical level, blood vessels, nerves and mandibular canals of mandibular angle region were observed. RESULTS: The distances from great auricular nerve, external jugular vein, cervical branch of facial nerve, facial artery and facial vein to the mandibular angle were (19.48?6.45), (13.84?3.78), (9.58?3.05), (22.62?7.16) and (20.08?6.45) mm, respectively. The distance from the location of marginal mandibular branch of facial nerve running out of the parotid gland to the mandibular angle was (7.79?2.57) mm. The distance from the location of mandibular canal at outer margin of third molar to the mandibular angle was (16.97?2.24) mm. CONCLUSION: The anatomical structure of the mandibular angle region is complex, and there are many important blood vessels and nerves. Minimally invasive incision at auriculocephalic sulcus is relatively safe in anatomy.
