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.

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.

0.05).The comparison of operating time and hospital stay was not performed due to insufficient data.Conclusion:Relative small J-pouch and straight anastomos is provided similar early results after low anterior resection.Both of these methods were proved to be safe and effective.

Natural killer cells are the key effector cells in innate immune response,playing the role in pathogen clearance and tumor immunosurveillance by cytokine secretion and cytotoxicity.Hematopoietic stem cells go through developmental intermediates to generate mature NK cells under the progressive regulation of extrinsic factors and intrinsic factors.In the past thirty years, great progresses have been made in the developmental progress,niches,regulation of NK cells and the relationship between NK cells and dis-eases.In this review,we will discuss in detail the molecular mechanisms of NK cell development and the diseases caused by functional compromise of NK cells.

The incidence of coIorectaI cancer is increasing in recent years. Liver metastasis is the main cause of death in patients with coIorectaI cancer. EarIy diagnosis and treatment of Iiver metastasis is important for improving the survivaI rate of patient. Liver metastasis in coIorectaI cancer is a muIti-step progress invoIving many genes and moIecuIar aIterations,detecting the abnormaI changes wiII heIp to assess the earIy risk of Iiver metastasis. This articIe reviewed the advances in studies on assessment of Iiver metastasis in coIorectaI cancer.

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.

In the recent few years,apart from the development of interventional technology,the development of new kinds material for packing intracranial aneurysms has hastened the promotion of endovascular interventional treatment greatly. Microvention company introduces lately Hydrocoil,a kind of hydro-agglutinated microspring coil which adopts a special hydrolink detachment technology,enriching the methods of endovascular treatment for cerebral aneurysms. Hydrocoil is a traditional platinum coil coated with expandable,unabsorble hydrogel material,which can improve the filling volume proportion of the aneurysm. At present it has been initially applied in clinic. This article summarizes the characteristics,the preclinical study,and the clinical application of Hydrocoil.(J Intervent Radiol,2007,16: 710-713)
