New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

The medical order number of a blood transfusion is used as the matching number in the full range of clinical blood use. A cycle is built ranging from the application for to the implementation of a medical order for blood transfusion. Such measures as repeated blood types verification by two departments, dual-database management of blood type files, and bar coding are called into play to ensure information correctness. These measures can make sure that the correct blood type is transfused to the correct patient and rule out accidents in blood transfusion. Indications for blood products are set up under real-time surveillance, which makes available limited blood products supply to those in need and minimizes waste and abuse of such products. The full-range and real-time management of clinical blood use will confine blood transfusion indications and ensure patients' safety with 100% match ratio.

Objective To investigate the effects of biological characters of the human ovarian cell line (OVCAR) by stable transfection short hairpin RNA into the target HMGA1 gene. Methods Experiments were divided into two groups: transfected the OVCAR cells with pSilence4. 1-CMV-Hs plasmid as group A, while transfected OVCAR cells with pSilence4. 1-CMV-Hn plasmid as group B, in which stably transfected cells were gained by antibiotic screening. The comparative expressions of HMGA1 were detected by RT-PCR and western blot. Methyl thiazolyl tetrazolium (MTT) method was applied to measure cell proliferation and at the same time, the cell growth curve was also be mapped. Vitro invasion assay was used to observe the invasion ability of the cancer cells, and the tumor growth of the nude mice inoculated of tumor cells were compared with before and after transfection. Results In group A, the expression level of mRNA and protein HMGA1 gene in OVCAR cells were remarkably reduced before and after the stable transfected with HMGA1 siRNA, in which the percents of mRNA expression were [(86.3±2.7) % vs. (35.8± 3.1) %, P<0.05], the expression of protein were [(68.6±2.8) % vs. (22.3±4.2) %, P<0.05)]. The OVCAR cell growth in stable transfection status was more significantly decreased than that in non-transfection status (P<0.05). In group B, there were no statistical difference in the expression of HMGA1 siRNA, protein and the cell growth between before and after transfection states (P>0.05). The invasion cell numbers were reduced from before to after transfection state in group A [(53±6)vs. (21±6), P< 0.05] ,while there was no significant difference in group B [(51±6)vs. (47±8), P>0.05]. After inoculated transfected cells into nude mice, it took (6.0±0.9) days to grow the planed tumors in group A, which was much shorter than that (12.3±3.9) days in group B (P<0.05 ). After 5 weeks, the tumor weight and volume in group A was were significantly lower than those in group B [(0.8±0.3)g vs. (2.1± 0.4)g, (205±34)mm~3 vs. (987±82) mm~3, all P <0.05]. Conclusion HMGA1 siRNA could remarkably reduce the expression of HMGA1 gene in ovarian cell and also inhabit the ovarian cell growth.

Quantitative measurement of strain distribution of arterial vessel walls due to pulsatile blood flow within the vascular lumen is valuable for evaluating the elasticity of arterial wall and predicting the evolution of plaques. The present paper shows that the three-dimensional (3D) strain distribution are estimated through uni-directional coupling for 3D vessel and blood models reconstructed from intravascular ultrasound (IVUS) images with the computational. fluid dynamics (CFD) numerical simulation technique. The morphology of vessel wall and plaques as well as strain distribution can be visually displayed with pseudo-color coding.

Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.

Objective Diabetic cardiomyopathy is a heart disease that excludes coronary heart disease,hypertensive heart disease and other heart diseases,and patients with diabetes mellitus prone to cardiac structural and functional changes.Echocardiography is often the first choice of examination methods,and nuclear magnetic resonance and nuclear magnetic resonance imaging is a new method to observe the changes of myocardial fibrosis and myocardial metabolism.In the treatment,need to a variety of methods to intervene,such as blood glucose control,using statin lipid -lowering drugs,angiotensin converting enzyme inhibitor,angiotensin receptor blocking agent,beta blockers,antioxidants,and traditional Chinese medicine etc.

The humanistic quality education of undergraduate clinical medical students is a system of education throughout the whole process of medical education.Some aspects include new career planning education,medical humanities quality courses,social practice,professional courses,clinical practice and evaluation of humanistic quality education need to design and control,which are necessary to achieve a good education results.

Objective:To investigate whether plasma lipoprotein-associated phospholipase A_(2)(Lp-PLA_(2)) activity correlates with severity and stability of coronary atherosclerosis and other established cardiovascular risk factors.Methods: Coronary angiography(CAG) was performed in 180 hospitalized patients who were suspected as having coronary heart disease(CHD).The severity of pathological changes of the coronary artery was assessed by the number of diseased coronary branches and Gensini′s score.According to the results of CAG,the 180 patients were divided into 2 groups: CHD group(n=112) and non-CHD group(n=68).The CHD patients were further divided into subgroups according to the clinical types,the number of diseased coronary branches and Gensini′s score.Lp-PLA_(2) activity,white blood cell(WBC) count,high sensitive C reactive protein(hsCRP),lipids,blood pressure and body mass index were measured.The age,sex and prior medical histories including hypertension,diabetes mellitus and smoking status were obtained before CAG in all patients.Lp-PLA_(2),WBC count and hsCRP were compared statistically between the subgroups,and correlation coefficients of Lp-PLA_(2) activity with WBC count,hsCRP and other conventional risk factors for CHD were calculated.Results: Plasma Lp-PLA_(2) activity in CHD patients was significantly higher than that in controls(P
