OBJECTIVE:To discuss the disposal of essential oil in the preparation process of solid preparations containing Ligusticum chuanxiong and Angelica dahurica.METHODS:Based on pertinent literature in recent years,the disposal of essential oil in the preparation process of solid preparations containing Ligusticum chuanxiong and Angelica dahurica was discussed from aspects of chemical components,pharmacology and extraction process etc.RESULTS & CONCLUSION:It is necessary to combine research on preparation process with the pharmacological effect and pharmacodynamic action,and to formulate effective measures to control quality of the essential oil during the whole preparation process to facilitate a solution for the disposal of essential oil.

Medicine is a comprehensive discipline.Under the new situation,medical students are required to have integral knowledge and whole view.This article aims at evaluating the necessity of diagnosis and discusses the defects,causes and strategy in this respect.

Objective:To investigate the family history of congenital heart disease (CHD) in Chogqing for studying the genetic relation of CHD families. Methods:The materials were collected from the population survey about families with more than one members being CHD patients. Map pedigrees for high-risk families were made. The probands and the first and second grade relatives were asked to fill in questionnaires and the high-risk families were analyzed. Results:In the survey of 4387 families, there were 21 high-risk families in which the disease types of the relative patients were inconsistent with those of the probands, the coincidence being 33.33%(7/121).The incidence rates of the first and second grade relatives were 16.49%(16/78),1.89%(5/265) respectively and their difference was significant ( ? 2=27.73, P

Teachers'quality is an essential factor to improve teaching,and nowadays,lack of medical English teachers has become a serious problem many medical colleges have to deal with in our country. While designing the cours "eMedical English Watching,Listening and Speaking" ,English teachers,relying on their advantages of oral communication in English,can learn more basic medical theories and knowledge,and can gradually be trained as qualified medical English teachers after several years'teaching practice.

Dry eye is the most common ocular surface diseases encountered in the clinic.At present,a system for dry eye diagnosis and treatment has initially been formed in China,but there are still many clinical issues need to be resolved.It is important to improve the definition of dry eye and construct a more rational classification system;pay attention to the epidemiological investigation of dry eye;standardize diagnostic procedures for dry eye;establish the dry eye diagnostic criteria and the correct treatment concept.We propose to develop the clinical guidelines on dry eye classification,diagnostic criteria and treatment principles.

Free fatty acids(FFAs) provide an important energy source and also act as signaling molecules.Medium to long-chain free fatty acids can activate the intracellular signal pathways in the pancreatic ?-cells and play a role in regulating insulin secretion as an extracellular signal molecular via binding to the FFA receptor G protein-coupled receptor 40(GPR40). Furthermore,GPR40 is associated with several biological effects including cell proliferation and antiapoptosis of nerve cells.GPR40 act an important role in the connection of obesity and diabetes or cancers.GPR40 will probably become a novel kind of antidiabetic and anticancer drugs.

OBJECTIVE: To establish the quality standard of Codonopsis lanceolata.METHODS: C.lanceolata was identified by TLC and the content of ginsenoside in C.lanceolata was determined by HPLC.RESULTS: The TLC spots of syringin and echinocystic acid were clear and easy to identify.The linear range of ginsenoside in C.lanceolata were 2.176～21.76 ?g (r=0.999 8) with an average recovery of 96.54%(RSD=1.2%,n=9).CONCLUSION: Established quality standard can be used for the quality control of C.lanceolata.

The developing process of thermal comfort was analyzed based on physiology and psychology and the relationship between thermal comfort and human health, environment was discussed in this paper.It suggested that the thermo-stable and thermo-comfortable environment, which might decrease body's adaptability to environment, were not necessarily good for human health. It might have some impacts on human's physiological and psychological adaptabilities also to live in the environment with a great difference between the indoor and outside temperature simultaneously and alternately.

To increase the identification of pharyngeal bursa invasive fungal disease with lower cranial nerve involvement, reduce the misdiagnosis and improve the awareness of invasive fungal disease.
