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.

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.

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.

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 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.

Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.

ObjectiveThis paper discusses the instructional design of ＂General survey of medical culture＂,to provide the basis for the implementation of the teaching.MethodsThe first round of our teaching situation was concluded,to improve the teaching objectives,content,methods and the content and methods of teaching evaluation.Results The course is a new medical humanities curriculum to improve medical knowledge of the human spirit of nursing students,training the cultural literacy,but the teaching content should be combined with professional features,and teaching evaluation methods should be improved.ConclusionsRigorous designed curriculum,flexible and diverse teaching methods and forms of assessment and suggestions from the students are conducive to the improvement of the course.

Objective To summarize the main nursing point and experience of allogeneic small bowel transplantation.Methods One case underwent allogeneic small bowel transplantation in our hospital on the first of December 2010,the nursing measures were summarized.Results The patient passed the operation well-off,and survived the infection phase and repulsion phase in the transplantation ward.Conclusions Valid preoperative evaluation,taking active measures to prevent intraoperative hypothermia and infection,using self-made vacuum pads to prevent pressure sores during operation,are the guarantees for successful operation.
