Objective:To analyze geometry topography and the characteristic diffraction peaks of powder X-ray diffraction Fourier pattern for Baiziyangxin Pills and establish its quality standard.Methods:X-ray diffraction Fourier patterns for Baiziyangxin Pills have been analyzed and calculated by powder X-ray diffraction methods.Results:The standard X-ray diffraction Fourier pattern and characteristic diffraction peaks of Baiziyangxin Pills were obtained. Conclusion:The powder X-ray diffraction Fourier pattern analysis is able to be used for the identification of Chinese Patent medicine.

Objective Since there are significant variation of the dietary structure recent years in China,it is necessary to re-investigate the fatty acid composition of human breast milk for the presentation of the latest data of fatty acid composition in China. Methods Using a gas chromatography GC-2010,the composition of fatty acids was detected in the human colostrums and the mature breast milk(consecutively from postnatal day 1 to day 7 and from postnatal day 42)obtained from 62 healthy postpartum women in Shanghai and Chongqing,two big cities of China,from Jan to July,2008. Results The level of total fatty acid(TFA)tended to increase significantly from the colostrums to the mature breast milk. No significant difference in the level of TFA was found between two cities. The significantly higher monounsaturates(MUFA)level(44.06% vs. 33.85%,P ＜ 0.01)and lower linoleic acid(LA,C18 : 2n-6)level(18.43% vs. 27.62%,P ＜ 0.01)of the mature breast milk were observed in Chongqing women compared with those in Shanghai women. The docosahexenoic acid(DHA)level of the mature breast milk in Shanghai women was significantly higher than that in Chongqing women(0.41% vs. 0.29%,P ＜ 0.01). There was no significant difference in the level of arachidonic acid(AA,C20 : 4n-6)between two cities. Conclusions The fatty acid composition in human breast milk tends to vary with the extension of the lactation. There is significant difference in the fatty acid compositions in human breast milk between Shanghai and Chongqing owing to different dietary habits in the different regions of China.

Objective: To develop a new identification and analysis method of crude drug Pheretima . Method: Powders of pheretima were identified by means of X ray differacion Fourier pattern. Results: Experiments and analysis were carried out on five samples of pheretima. The standard X ray diffraction Fourier pattern and characteristic diffraction peaks of Pheretima were obtained.Conclusion: This method can be used for identification on crude drug Pheretima .

Objective To explore the clinical characteristics, etiology and prognosis of orbit apex syndrome. Methods Clinical data of 18 patients with orbit syndrome was summarized and analyzed. Results All patients developed vision loss, ptosis and diplopia, such as a headache or sore eyes forehead performance. However, the onset symptoms varied including vision decline or loss in 8 cases, headache in 7 cases, eye pain in 1 case, toothache in 1 case, stuffy nose and runny nose in 1 case and exophthalmos in 1 cases. The Causes included trauma in 6 cases (33％), mass lesion in 5 cases (28％), nonspecific inflammation in 1 cases (22％), infection in 3 cases (17％). Vision and eye movements disorder were improved in 5 cases of 6 patients with trauma in which 3 mild cases recovered better and one severe case did not recovered. Of 5 patients with mass lesion, the vision and eye movement were improved in one patients with sphenoid sinus mucocele receiving surgical operation. but not in the rest 4 cases with orbital adenoid cystic carcinoma or osteosarcoma patients receiving either surgical operation or radiotherapy. Of 4 patients with nonspecific inflammatory disease, eye movements were improved in 2 mild cases but not in 2 severe cases. Of 3 infectious diseases, eye movements were improved in 1 mild case. Conclusion Orbital apex syndrome is a heterogeneous disorder with multiple etiologies, presenting with a variety of initial symptoms. The prognosis depends on causes, timely diagnosis, early diagnosis and early treatment.
