Objective To explore the effect of different processes on the contents of active ingredients in Rhizoma Corydalis. Methods Processes of vinegar-boiling, vinegar-frying and alcohol-frying were used to fresh corydalis, boiled corydalis and purchased corydalis. Then the method of extraction by ultrasound with water and by reflux with methanol were used to extract the sample. The contents of Protopine, Tetrahydropalmatine and Dehydrocorydaline in corydalis was determined by RP-HPLC. Agilent TC-C18 (25 mm?4.6 mm, 5 ?m) column was used at 35 ℃, with acetonitrile-0.1% phosphonic acid (pH 5.3 with triethylamine) (28∶72) as mobile phase. The flow rate was 1 mL/min and detection wavelength was set at 280 nm. Results In the sample extracted by water, the contents of active ingredients in processed products were higher than in corydalis. And in the sample extracted by methanol, it also has the tendency that the contents of active ingredients in processed products were higher than in corydalis. The content of Dehydrocorydaline in fresh corydalis which was processed by vinegar-boiling, vinegar-frying and alcohol- frying was high. The content of Tetrahydropalmatine in purchased corydalis which was processed by water-boiling at production place was high. Conclusion The method of determining active ingredients in Rhizoma Corydalis was established. It was convenient and the result was accurate. The process technology that fresh corydalis was boiled by water and then processed or fresh corydalis was processed in production place can be used.

BACKGROUND:Ultrasound has been widely used in developmental hip dysplasia screening in infants and young children, but there are significant differences among different inspection findings, even in the reexamination by the same examiner. Therefore, the accuracy of ultrasound imaging in the diagnosis is of insufficient evidence.
OBJECTIVE:Through virtual reality three-dimensional reconstruction images showing the structure of acetabulum and femoral head space, to obtain a new parameter in order to enrich measurement standards of Graf ultrasonic diagnosis technology and to further improve the credibility of the diagnosis of developmental dysplasia of the hip.
METHODS:Ten fresh cadaver specimens of Chinese infants were selected, including five males and five females. Two-dimensional ultrasonic method was employed for hip screening, and at the same time, multi-slice spiral CT was used for three-dimensional reconstruction fol owed by volume reconstruction and fitting of surface reconstruction to display the anatomic structure around the hip and to simulate Graf’s two-dimensional ultrasound method to measure a andβangles on three-dimensional virtual reality images.
RESULTS AND CONCLUSION:As confirmed by three-dimensional reconstruction, Graf’s two-dimensional ultrasound could be used to measure a and angles, truly reflecting the development of bony and cartilaginous acetabulum. Graf’s two-dimensional ultrasound contributed to the proper evaluation of beonatal hip dysplasia, which can be used as a routine examination for developmental dysplasia of the hip. These indicate that to master Graf’s ultrasound technology and strictly grasp the evaluation standards for developmental dysplasia of the hip is the important guarantee for diagnosis of developmental dysplasia of the hip.

Objective To study the changes of oral flora in patients with diabetic ketoacidosis,in order to provide evidence for making oral nursing intervention and hygiene education. Methods 35 patients with diabetic ketoacidosis were named as group A,35 non-diabetic patients with chronic periodontitis (diagnostic criteria:periodontal pocket 14 mm) were named as group B,35 nonketotic patients with diabetes mellitus were named as group C,then all the patients were detected for the oral disease and the oral hygiene was evaluated. Results The gingival index,plaque index,tooth mobility,probing depth and hemorrhage after the detection of three groups had no significant differences. The detection rate of streptococcus oralis, lactobacillus,fusobacterium nucleatum,black-pigment bacteria,Capnocytophaga gingivalis,actinomycetes, escherichia coli,staphylococcus aureus and pseudomonas aeruginosa had no significant differences,there was a positive correlation between quantity of black-pigment bacteria, Capnocytophaga gingivalis and fasting blood glucose and glycosylated hemoglobin of patients with diabetic ketoacidosis. Conclusions Diabetic ketoacidosis strengthened the bacterial invasion and oral colonization of patients.

OBJECTIVE:Tosum up the condition of theoretical teaching and experimental teaching of the Processing of Chinese Materia,and to provide referencefor the reform of teaching model of the Processing of Chinese Materia. METHODS:Teaching soft-ware,teaching video and other modelrn teaching methods were used to enrich the content in theory teaching;linking theory with practice was used to stimulate students'interest in learning;scientific research achievement was introduced in teaching to train stu-dents' scientific research thinking;the teaching model of traditional confirmative experiment teaching was reformed by increasing de-signing experiment hours and score;the traditional usual performance evaluation method was changed by replacing with evaluation method of formative,and it was used for evaluation. RESULTS:The students not only learned theoretical knowledge,but also cul-tivated their ability to analyze and solve problems,changing from passive learning to active learning,so that it has made satisfacto-ry teaching effect. CONCLUSIONS:The traditional concept should be changed in teaching of the Processing of Chinese Materia, paying attention to the combination of scientific research and teaching;improve the situation of the designing experiment in the present undergraduate experimental teachingto stimulate students interest in learning,enhance students'practical ability,and im-prove the quality of teaching.

In recent years,with the development of the bio-psycho-social medical model,more and more attention has been paid to the relationship between psycho-emotional factors and liver.According to traditional Chinese medicine theory,the liver is mainly responsible for catharsis and regulating emotion,which is closely related to emotion.Epidemiological studies have shown that all kinds of liver diseases are accompanied by different degrees of mental disorders,and mental and emotional abnormalities may promote the occurrence of liver diseases and affect the prognosis.Liver and emotion have a common pathogenesis in pathology,involving the dysfunction of nervous,endocrine and immune systems.Based on the basic theory of traditional Chinese medicine and modern medical research,this review analyzes the correlation between emotions and liver.At the same time,neurotransmitters,inflammatory cytokines,brain-derived neurotrophic factor(BDNF),soluble epoxide hydrolase(sEH),intestinal microecology,hypothalamic-pituitary-adrenal(HPA)axis and hypothalamic-pituitary-thyroid(HPT)axis,which summarizes the potential mechanisms of liver disease complicated with emotional disorders,and provides certain reference value for future theoretical research and clinical treatment.

OBJECTIVE To investigate the effects of different drying methods on the index components in wine-processed Cornus officinalis so as to optimize drying method.METHODS After processed with wine, C. officinalis decoction pieces were dried with different drying methods (blast drying, far infrared drying, microwave drying, freeze drying, sun drying, shade drying and combined drying). The contents of 5 components such as gallic acid in wine-processed C. officinalis were determined by high- performance liquid chromatography. The contents of total flavonoids in wine-processed C. officinalis were determined by chromogenic method. Analytic hierarchy process was used to evaluate the effects of different drying methods on the contents of components in C. officinalis.RESULTS The contents of gallic acid, 5-hydroxymethylfurfural, monoside, loganin, cornuside and total flavonoids in 22 batches of wine-processed C. officinalis were 1.043 8-1.563 8, 0.648 5-2.358 8, 5.031 0-10.305 7, 6.681 2- 7.534 2, 0.986 5-1.148 8 and 33.657 2-50.741 5 mg/g, respectively. The comprehensive scoring results of analytic hierarchy process showed that the comprehensive score of each component in C. officinalis dried by microwave at 75 ℃ was higher , followed by blast drying at 60 ℃ and far infrared drying at 60 ℃ .CONCLUSIONS The wine-processed C. officinalis could be dried by microwave drying at 75 ℃, blast drying at 60 ℃ or far infrared drying at 60 ℃.
