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.

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 .

BACKGROUND: A silk fibroin/chitosan scaffold has good biocompatibility, osteoinductivity and degradability.OBJECTIVE: To review the structure, performance and application of the silk fibroin/chitosan scaffold in bone,cartilage and soft tissue engineering regeneration.METHODS: PubMed, Wanfang, and CNKI databases were retrieved by computer for articles related to the structure, performance and application of the silk fibroin/chitosan scaffold in orthopedics published from 1998 to 2016. The keywords were chitosan, silk protein, bone tissue engineering in English and Chinese, respectively.RESULTS AND CONCLUSION: The silk fibroin/chitosan scaffold is characterized by good biocompatibility, bone inductivity and biodegradability that make cells grow well on the scaffold. The silk fibroin/chitosan scaffold has been widely used in bone tissue engineering, and has a prominent performance in bone defect repair and cartilage injury treatment. Meanwhile, the silk fibroin/chitosan scaffold exerts a crucial role in wound healing as well as in the treatment of spinal nerve injury and other soft tissue injuries. However, the silk fibroin/chitosan scaffold currently is less reported in the clinical use due to various reasons, and it will be the main research direction of future efforts. As is known to us, silk protein can be used to prepare the cruciate ligament and construct tissue-engineered nuclei; therefore, the silk fibroin/chitosan scaffold can be developed in the treatment of tendon ligament injury and intervertebral disc tissue engineering.

Esophageal reconstruction is of great importance in the practice of esophagectomy,and esophagogastric anastomosis represents the most essential and key technical aspect of the operation,which largely determined patients' shortterm outcomes.A successful esophageal anastomosis should be no occurrences of postoperative early-stage anastomotic bleeding and leakage and later-stage anastomotic stenosis.The circular stapler,linear cut stapler and hand-sewn anastomosis are the most common anastomotic methods.Hand-sewn anastomosis is the most traditional and classical.Circular stapler has gained significant popularity for its simplicity and convenience.Linear cut stapler used for side-to-side anastomosis has the potential to reduce the risk of postoperative anastomotic stenosis via expanding inner diameter of anastomosis.Every anastomotic method has its advantages and disadvantages,and it cannot completely avoid occurrence of postoperative anastomotic complications.To have a better outcome,both surgeon's experiences and patient's individual conditions should be taken into consideration for the choice of anastomotic technique.

Medical safety management and non-medical safety management are two major systems of hospital safety management.With the deepening of the medical and health system reform and the change of the mode of medical treatment,the connotation and extension of non medical safety management have changed,and the non-medical safety management field is faced with more risk factors and security risks.Combined with the.status quo of non medical safety management in hospital,the problems existing in non-medical safety management are analyzed and some suggestions for improvement are put forward.

In this paper,performance of decompression and low coated gas chromatographic column of non-polar liquid phases is described. Chromatographic parameters of a column packed with 0.5% OV-101 on glazing support (φ0.18～0.25mm) 302 was studied for C、C7、C8、C9 n-alkanes samples. The results showed that the column pressure 0.068 MPa was best,the column temperature for n-octane could be decreased to 52°C,column efficiency was four time as high as ordinary pressure detection.

Human DAB2 interaction protein (DAB2IP) is a novel member of Ras GTPase-activating protein family. It interacts directly with disabled-2 protein (DAB2/DOC2) which suppresses growth of cancers derived from different tissues, including mammary, prostate and ovarian cancers. DAB2IP was identified as an immediate downstream effector mediated by DAB2/DOC2. DAB2IP and DAB2/DOC2 form a unique protein complex that has a negative regulatory effect on the Ras-mediated signal pathway. It is demonstrated that DAB2IP is a tumor suppressor gene inactivated by methylation in several cancers. This article reviews the structure and biological functions of DAB2IP gene as well as its potential roles in carcinogenesis and evolution.
