The advantages and disadvantages of various echocardi-ography including Color, pulse doppler.Two-dimensioaal and M-mode were evaluated in the detection of Coronary artery disease. A total of 47 patients with Coronary artery disease and 17 cases of healthy control were studied by above mentioned 4 different eehocardio-graphy. The results were analysed and showed chat such an examintion was helpful and practical for detection of Coronary artery disease without motion of ventricular wall

Medical institutions bear the important task of cultivating medical professional talents,and superb medical technology level and decent moral quality are the basic objectives of personnel training.Morality construction related to the overall level of teachers in medical institutions,thus it is a critical content of college personnel management to focus on the practical status quo of young teachers in medical institutions and innovate new ways of morality education.

Colorectal cancer is one of the most common cancer.Despite the survival rate of patients with metastatic disease has been raised due to the combination therapy of chemotherapy and opetation,few longterm survivors exist.The detection of circulating tumor cells (CTC) is an evolving technology whose significance has been discussed for more than a century.The advence of modem technology has allowed for more reliable detection of CTCs,and recent studies have provided compelling evidence that CTCs can predict clinical outcome in metastatic colorectal cancer (mCRC).In this review,we will discuss the evidence for CTC significance,with particular focus on detection methods,novel markers,and clinical outcomes in CRC,and future challenges in testing them as a means to individualize the therapy of mCRC patients.

BACKGROUND:Femoral head necrosis induced by glucocorticoid is typical under mechanics load.OBJECTIVE:To create the rat models of the femoral head necrosis by long-term glucocorticoid treatment,and to Observe the changes of femoral head necrosis induced by glucocorticoid under mechanics load.METHODS:Wistar rats with 4-month old were randomly divided into the experimental and control groups.After the buttocks injection of dexamethasone 20mg/kg weakly for 8 weeks,rats in the experimental group were made to run on the running machine at a speed of 1 km/h to forme the hyper-weight model;at the same time those in the control group were with the normal physiological weight.Rats in both groups were sacrificed at weeks 2,4,6 and 8.The left legs were taken for the biomechanics test on the EnduraTEC ELF3200,the biggest vertical deformation and stiftness were calculated,the number of empty osteocyte lacunas was calculated,and the cumulative absorbance value was compared between two groups.RESULTS AND CONCLUSION:The femoral head presented with necrosis at 8 weeks in the experimental group.and the width of bone trabecula,and the stiffness of which were smaller than that of the control group.but the biggest vertical deformation was greater the concurrent control group(P＜0.05).The Bcl-2 cumulative absorbance value of 2 groups had significant differences at 4 weeks(P＜0.05),which was increased with time prolonged in the experimental group(P＜0.05).The results demonstrated that:in glucocorticoid-induced osteonecrosis of the femoral head,mechanics Ioad induces the obviously osteocyte necrosis.more cartilage repair,and trabeculae rupture,which is considered as the direct reason of the necrosis of the femoral head The typical femoral head necrosis is presented.

Hypcrlipidemia is one of etiological factors of pancreatitis,of which the genesis has somewhat speci ficity.This article reviews hyperlipidemia related pancreatitis about its conception,etiology,classification,pathogene sis.specific clinical manifestation as well as diagnosis and treatment.

With the development of the ultrasonic molecular imaging,the invention of a variety of new ultrasound contrast agents can not only improve the sensitivity and specificity of the diagnosis,but also provide new ideas and means for early diagnosis and treatment of hepatocellular carcinoma.The development and perspective of the relative researches were described in this article.

As the passage of environmental atmosphere entering the body,the respiratory tract suffers persistent challenge from foreign substances.The mucosal immune system of the respiratory tract is the main defense line against the invasion of pathogens,which needs to distinguish not only beneficial and detrimental materials but also resident and pathogenic bacteria.Because the knowledge about respiratory mucosal immunity is limited,the immunopathologic mechanisms of related diseases such as asthma,acute lung injury, chronic obstructive pulmonary disease, and respiratory infection need investigation.The study about the immune features of the respiratory tract not only contributes to the prevention and treatment of respiratory disease but also provides ideas for the development and design of new vaccines and medicines.

Objective To evaluate the anti-oxidant effects of vitamin E -modified membrane in hemodialysis patients.Methods In our four-week study,57 patients on maintenance hemodialysis were divided randomly into three groups.Group A (n=19) resorted to hemodialysis with VitE-modified membrane;Group B (n=19) resorted to hemodialysis with conventional dialyzers and oral VitE intake(400mg/d);Group C (n=19) resorted to hemodialysis with neither vitamin E-modified membrane nor vitamin E intake.Blood samples were collected prior to the first and thirteenth dialysis sessions,and were employed to determine the concentrations of malonylaldehyde (MDA),glutathione peroxidease (GSH-px),glutathione (GSH),superoxide dismutase (SOD) and Vitamin E in plasma and red blood cells (RBC),and advanced oxidative protein products (AOPP) in plasma.Results In group A,there were significant increase in VitE,GSH-px,GSH and SOD levels,and declined MDA and AOPP levels in plasma and in RBC(P0.05).Conclusion Our study suggests that VitE may have anti-oxidant effects on hemodialysis patients,and that VitE-modified membrane may have more advantages in anti-oxidative effect compared with.VitE oral administration.

Objective To observe long-term clinical and rehabilitation effect of Xingnaojing injection with hyperbaric oxygen on the stroke patients with hemiplegia.Methods100 patients with cerebral apoplexy hemiplegia from May 2012 to April 2014 in Wuzhong City People's Hospital Affiliated to Ningxia Medical University during the period.According to the stochastic indicator method, the object of this study were divided into experimental group (50 cases) and control group (50 cases).For all patients with conventional treatment, daily aspirin 0.5 g, nim horizon each time, three times a day oral treatment, control group patients on the basis of the joint 20 mL Xingnaojing injection, once a day.Patients in the experimental group were given hyperbaric oxygen treatment on the basis of the combination, for an hour every day.Treatment for 2 months after hospital discharge, 18 months after treatment to return of two groups of patients, compared two groups of patients before and after treatment action, ability of daily life, the quality of life as well as the secondary injury, and the patient's neurologic deficits were evaluated.ResultsIn 18 months after treatment, the treatment group patients walk rate was 68%, significantly higher than that of control group 42%(P<0.05), nerve function defect assessment in experimental group patients was (10.43±2.19) scores,was significantly better than control group (16.04±3.23) scores, daily life ability, life quality and improve secondary injury effect in experimental group was significantly better than control group, difference has statistical significance (P<0.05).ConclusionXingnaojing injection combined hyperbaric oxygen treatment of stroke patients with hemiplegia, can improve long-termdaily life skills, and improve quality of life with rehabilitation, the long-term clinical effect is remarkable, less adverse reaction.

Objective To utilize the PBL method for the teaching reform of pedodontics lesson in Zhengzhou University. Methods Dental students of 2004 grade of Zhengzhou University were divided into 2 groups randomly,one group of which were taught with PBL method while the other group with traditional teaching method. The teaching effect was measured with questionnaire survey and examination. Result The PBL method was welcomed by undergraduate students and there was statistical significant difference between the examination scores of the two groups (P
