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.

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

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 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.

BACKGROUND: The question whether patellar replacement is necessary during total knee arthroplasty remains controversial. The influence of different parameters, such as patellar thickness, bone bed shape, fixation column style and fixation patterns on effect of total knee arthroplasty remains unclear. OBJECTIVE: To induce the technical parameters in patellar replacement. METHODS: A computer-based line seerch of CNKI and Pubmend was performed for articles published between January 1999 and June 2009 with key words "artificial knee joint, petellar replacement" in Chinese and "artificial knee joint, arthroplasty, patellar surfacing" in English. Clinical studies of patients undergoing patellar replacement or not dudng total knee arthroplasty were included. Animal experiments were excluded. The indication and complication of patellar replacement, issues regarding patellar replacement, influence of petellar thickness reservation on artificial knee arthroplasty, prosthesis design of patellar and influence of internal fixation pattems on postoperative effect, and influence of replacement techniques on artificial knee joint were discussed in this article. RESULTS AND CONCLUSION: Currently, patellar replacement is considered to have three patterns: total replacement, no replacement and selective replacement. The shape of patella remains controversial. Bone cement is commonly used for patellar prosthesis fixation. The pdnciples of patellar replacement are as follows: to maximize patellar thickness; to maintain articular facet symmetry; to protect patellar blood transport; to ensure reasonable motion track of the patella. The indications of patellar replacement depend on protopathy, pathological change degree, prosthesis pattern, patient activity amount and body mass.

Safflower Yellow is the essential component of Chinese traditional medicine Carthamus tinctorius with the effect of promoting blood circulation and removing blood stasis .Clinical studies have found its obvious curative effect in cardiovascular and cere -bral vascular diseases .Clinical treatment of angina , hyperlipidemia , cerebral infraction and arterial type cervical spondylosis in recent years was reviewed , which can provide references for treatment of cardiovascular diseases with Safflower Yellow .

Objective To explore the correlation of infants with asthma and food allergens,to povide the basis for early prevent the development of asthma.Methods The U-niCAP-100 automatic detection system was used to check the common food allergens in serum of 79 infants with asthma and 68 healthy children of the same age.Results The positive rate of serum total IgE in the group of asthma was 64.6％,significantly higher than the healthy group (45.6％)(P＜0.01).The positive rate of serum SIgE was showed that:the mainly food allergens of the asthma group was milk(63.2％)and whole egg(26.3％)which were,significantly higher than the healthy group(36.8％,14.7％)(P ＜ 0.01 and P ＜ 0.05).Conclusion Asthma of infant had close relation with the food allergens.Early avoid food allergens had an important role in preventing the development in low-age children with asthma.

Objective To observe and evaluate the efficacy of the preventing antibiotic-associated diarrhea in infant with bacterial pneumonia using the live Clostridium butyricum and Bifidobacterium combined Powders. Methods 103 infants with bacterial pneumonia were randomly divided into the two groups,53 infants as the trial group,another 50 infants as the control group with normal antibacterial therapy,two or three hours afterword the live Clostridium butyricum and Bifidobacterium combined Powders was administered at dose of 0.5g ti-daily in the trial group,After diarrhea taken place,the live Clostridium butyricum and Bifidobacterium combined Powders was adminis-tered at dose of 0.5g ti-daily in the control group,to contrast the rate of secondary diarrhea and clinical efficacy in the two groups.Results The incidence of antibiotic-associated diarrhea was 13.2%( 7/53 ) in the trial group and 56.0%(28/50) in the control group (χ2 =21.00,P<0.01).There were significant differences between the two groups.Duration of diarrhea and period of treatment in the trial group was obviously shorter than that of the control group,the rate of dehydration in the trial group was lighter than that in the control group(χ2 =6.64,P<0.01). Conclusion The live Clostridium butyricum and Bifidobacterium combined powders with antibacterial therapy at reg-ular intervals can prevent antibiotic-associated diarrhea.It is worthy of preventive application.

BACKGROUND:To establish the real body’s artery model has its own limitations due to the diversity of different individual differences in the carotid artery and blood flow.
OBJECTIVE:To study the effect of different inlet velocity profiles of the common carotid artery and three different flow ratios of internal and external carotid artery on hemodynamics of the carotid artery.
METHODS:The carotid bifurcation TF-AHCB numerical model was established. Commercial software ANSYS was used to compute the flow field and calculate hematodynamic parameters, including velocity and wal shear stress. Then, their relationship with atherosclerosis was analyzed from different angles.
RESULTS AND CONCLUSION:Flow ratio of internal and external carotid artery significantly influences the flow field of the simulated bifurcation of the carotid artery. Changes in the magnitude of inlet velocity cannot only alter the hematodynamic properties, but also change the range of mechanical mechanism.
