Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

Objective To understand and analyse the epidemic status of human intestinal nematode infection in Jiangsu Province, so as to provide basis for making control measures. Methods The typical thirty-nine spots in thirteen counties among the sampling spots of National Investigation on Distribution of Human Parasites in 1990 were selected and investigated according to the Methods of National Investigation Scheme on Human Principal Parasites in 2004. Results The total prevalence was 3.88%, which decreased by 46.92% compared with the investigation in 2002 (7.31%). The infection rates of hookworm, Ascaris and Trichuris were 1.14%, 1.06% and 1.73%, respectively, and the proportion of light infection was 91.75%. The rate of multiple infections was 9.40%. The proportion of hookworm infection was 78.06% in Southern Jiangsu and the proportion of Ascaris or Trichuris was 89.03% in Northern Jiangsu. The infection rate of Enterobius was 3.72% among children aged less than 12 years. Conclusions The prevalence of intestinal nematodes has decreased to lower level in Jiangsu Province. The difference of prevalence in different regions has a relationship with the disease control and social-economic, culture and health levels. The principal control work should be still put in the northern part of Jiangsu Province. The preschool children and the middle and old age peasants are high-risk population. The different control measures should be taken in accordance with the situation of different regions in the future.

OBJECTIVE:To study the stability of baicalin magnesium salt. METHODS:The stability of baicalin magnesium salt at high temperature(60 ℃),high humidity(90%),strong illumination(4000 lx),different temperatures(20,37,50,60 ℃) and pHs(6.80,5.70,4.60,4.30,3.90,3.60,3.20) was investigated,and HPLC was used to detect the drug contents. RESULTS:High humidity test indicated that the quality of baicalin magnesium salt was increased by (6.17 ± 0.12)% in the 5th day and in-creased by(6.92±0.05)% in the 10th day. Drug contents in the 10th day were respectively(94.78±0.12)%,(94.79±0.20)%, (94.66±0.15)% in the high temperature,high humidity,strong illumination tests(n=3). In phosphate buffer solution(pH 6.80), baicalin magnesium salt was stable only when the temperature was below 20 ℃;and it was yet stable in pure water(pH 6.76)at 37 ℃. pH stability test showed that the most stable pH was 4.30. CONCLUSIONS:Baicalin magnesium salt has hygroscopicity to some extent. Strong illumination affects the stability more seriously than high temperature and high humidity. The stability of ba-icalin magnesium salt in pure water is superior to in phosphate buffer solution,and the salt is stable in weak acid solution.
