An investigation of palmar patterns on 900 cases Han nationality of China wasmade.The main purpose of this paper is to provide the normal values of Chinese dermatoglyphics and human genetics.The main characters of palmar patterns of Han nationality are as follows:mainline A:type Ⅰ 7.89%,type Ⅲ 91%,type Ⅴ 1.11%;main line B:type Ⅴ 80.72%,type Ⅶ 16.78%,type Ⅸ0.67%,type Ⅺ0.06%,type O(absent)0.11%,typeⅢ 1.67%;main line C:type Ⅴ 38.78%,type Ⅶ 32.67%,type Ⅸ 16.06%,typeⅪ0.44%,type O(absent)12.06%;main line D:type Ⅶ and type Ⅸ all 40.61%,type Ⅺ 18.39%,type O(absent)0.39%.The average value of AD main line formula is 6.50?1.61(SD).There are sig-nificant difference between sexes and two hands(R.L.)(P0.05).The frequency of complicatedpalmar creases is 5.22%.The rate of symmetrical main lines between two hands is34.89%.The main type of A.B.C.D main line is 3.5′.5″.7(18.11%).

This article was aimed to study the correlation between microstructure and stability of cream contained Span and Tween as compound emulsifier by factor analysis. Techniques such as microscopic observation and rheolog-ical examination were used to perform the microstructure. And the thermal analysis and near-infrared stability ana-lyzer was carried out to quantify characterization of the physical stability of cream. The results showed that among the series of S60-T80 and S60-T60 creams based on compound emulsifier, cream conductivity increased and more and more spherical lamellar liquid crystalline structures appear on micrographs with increasing Span 60 fraction. The greatest viscoelastic was appeared when the mass ratio of Span and Tween was 2:2 and 1:3, respectively. From the thermogravimetric analysis, the increase of Span 60 fraction led to the weight loss of samples between 50℃-70℃ in-crease, but it decreased within 70℃-110℃. It was concluded that there was positive correlation between the intensi-ty of microstructure and the ability of resistance to structural failure when the experiment conditions were stable. It had negative correlation with the hydrophilic gel phase water distribution index.

Objective To evaluate effectiveness of guideline-oriented training for community healthcare workers (HCWs) with The Applied Standards for Hypertension Prevention and Control at the Grassroots to provide guidance to hypertension management in communities. Methods In 2003, four community health-care service centers in Beijing were selected and assigned as intervention (one at urban and one at rural) and control (one at urban and one at rural ) groups, respectively. HCWs in the intervention group received guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots, while HCW in the control group did not. All HCWs participated in tests of the knowledge of hypertension management using the same questionnaire before and after the training to analyze their changes in awareness scores with a full of 32. Results There were 39 and 33 HCWs in the intervention group and 15 and 16 HCWs in the control group, respectively at urban, and 30 and 33 HCWs in the intervention group and 21 and 22 HCWs in the control group, respectively at rural before and after the training were involved in the tests, respectively. After training, overall knowledge scores of hypertension prevention and control in HCWs in the intervention group at urban increased obviously, with an average score of 26 of 32 ( 81.0% ) after training from 15 of 32 (45. 6% ) before it ( P ＜ 0. 01 ) , with a net increase of 28.5% (9/32), as compared to HCWs in the control group. Those at rural increased to 6. 6% (20/32) after training from 40. 7% (13/32) before it ( P ＜ 0.01 ), with a net increase of 22. 2 percent (7/32), as compared to HCWs in the control group. Their awareness of knowledge of hypertension prevention and control significantly improved, with the most obviously in the target of blood pressure control (51.7% vs. 31.5% ) and principles of pharmaceutical therapy (42. 2% vs. 27. 6% ). Conclusions Guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots can effectively improve community HCWs' awareness of knowledge of hypertension management and should be widely promoted in communities.
