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.

Objective To investigate whether HBx alone is sufficient to directly transform the nontransformed immortalized human liver cell line QSG7701 and induce hepatocellular carcinoma in vivo,and to explore preliminarily the pathogenic mechanism of transplantation tumor in nude mice.Methods The pCMVX/QSG7701 cells were vaccinated into subcutaneous tissue of nude mice.The pRcCMV2/QSG7701 and QSG7701 Cells were used as control.At the fifth weeks after vaccination,the nude mice were killed to observe whether a tumor was formed.The activity state and food intake of the nude mice was recorded.The texture,volume,and metastasis of transplantation tumor were observed grossly.The transplantation tumor was observed microscopically on the hematoxylin and eosin (HE) staining section.Immunohistochemical surfactant protein (SP) method was used to analyze the protein expression of mutant p53 and C-Myc genes.Results The transplantation tumor was occurred in all of the six nude mice vaccinated with pCMVX/QSG7701 cells at the second week after vaccination.No metastatic tumor was found in other organs.Transplanted tumor was not formed in all of the negative control groups.HE staining analysis confirmed that the character of transplanted tumor was hepatocellular carcinoma.p53 and C-Myc proteins were expressed in pCMVX/QSG7701,pRcCMV2/QSG7701,and QSG7701 cells,and their expression levels in the pCMVX/QSG7701 cells were significantly higher than those in the pRcCMV2/QSG7701 and QSG7701 cells,respectively(P ＜0.01).Conclusions HBx alone is sufficient to directly transform the non-transformed immortalized human liver cell line QSG7701 and induce hepatocellular carcinoma in vivo through up-regulating the expression of mutant p53 and C-Myc genes.

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.

Myasthenia gravis is autoimmune diseases which mediated with acetylcholine receptor antibody.Based on the studies in rencent years,treatment of MG has made great progress.Thisreview will discuss several aspects,such as immune tolerance induced by dendritic cells,blocking monoclonal antibodies,hematopoietic stem cell transplantion,and provide new ideas and methods for the treatment of myasthenia gravis.

Objective To investigate the pathogen and inspection methods of the middle-aged women with constipation and evaluate the accuracy and clinical application of imaging to constipation.Methods First colonic transit test were used to 98 cases of middle-aged women who were diagnosed constipation by doctors,then air-barium double contrast examination were applied.Defecation radiography or simulation rectum defecography were used to those who were diagnosed as outlet obstruction.According to the measure target and diagnostic criteria of professor LU,the results were studied.Results 6 cases were abnormal within 8 cases who were inspected by barium enema.14cases were abnormal within 16 cases who were inspected by defecation radiography.Colonic transit test were used to 74 cases and only 6 cases were normal.16 cases were true slow transmission and 20 cases were false slow transmission.52 cases were outlet obstruction.20 volunteers were inspected by suspension barium sulfate and simulation rectum defecography.Conclusions Air-bariun double contrast examination could discover the organic disease and abnormal of rectum.colonic transit test,defecation radiography and simulation rectum defecography were simply and perfect methods to discover the pathogen of constipation.

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 explore the application value of clopidogrel in patients with non ST segment elevation myo‐cardial infarction (NSTEMI) during emergency percutaneous coronary intervention (PCI) .Methods :A total of 168 NSTEMI patients treated in our hospital from Jan 2012 to Feb 2013 were randomly divided into clopidogrel group (n=84) and ticlopidine group (n=84) ,both groups received PCI .Therapeutic effect were observed and compared be‐tween two groups .Results:Compared with ticlopidine group , there were significant rise in percentage of TIMI blood flow grade 3 (88.1% vs .91.7% ) ,white blood cell counting [ (4.0 ± 2.9) 109/L vs .(7.2 ± 2.3) 109/L] and platelet counting [ (101 ± 35) 109/L vs .(141 ± 39) 109/L] ,and significant reduction in percentage of mild bleeding (40.5% vs .19.0% ) in clopidogrel group after operation 28d , P< 0.05 or < 0.01 ;compared with ticlopidine group , there were significant reductions in incidence rates of cardiovascular events (60.7% vs . 27.4% ) and adverse reactions (14.3% vs .10.8% ) in clopidogrel group after six‐month follow‐up ( P<0.05 both) .Conclusion:Clopi‐dogrel possesses satisfying therapeutic effect and high safety in patients with non ST segment elevation myocardial in ‐ farction during emergency percutaneous coronary intervention ,which is worth extension .
