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.

HPLC was applied to content determination of active components——chlorogenic acid and baicalin in Qingkailing Injection.This method is simple,rapid,involves good reproducibility,and can be as a reliable determination method for the quality control of Qingkailing Injection.The test conditions are as follows:detection wavelength at 340 nm,ODS C-18 chromatocolumn of stainless steel(3.9?30cm),mobile phase using methanol-water-tetrahydrofuran(25:57:18).

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 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.

Multiple myeloma (MM) is a heterogeneous disease.The prognosis of MM varied a lot among different patients.One of the main basis of risk stratification is genetic abnormality,which including the number or structure anomaly of chromosomes,genetic aberrations,signaling pathway disorders and epigenetic changes.The risk stratification is being revised with the development of FISH,gene-expression profiling and next-generation sequencing.These combined approaches would hopefully transform the current one-for-all care into a more tailored,individual therapeutic strategy for MM patients and would finally improve their quality of lives.

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.

Hypertension in children is defined as systolic blood pressure and/ or diastolic blood pressure≥95th percentile for age,gender and height,on at least 3 occasions. Persistent hypertension despite non - pharmacologic measures should be treated with anti - hypertensive drugs. Angiotensin - converting enzyme inhibitors,angiotensin receptor blockers,calcium channel blockers,β - blockers and diuretics are safe,effective,and well tolerated in children. This article describes the selection and clinical application of anti - hypertensive drugs in children.
