To explore the role of CDC25B in pathogenesis and development of colorectal cancer and to investigate the relation between the expression of CDC25B and the clinical pathological character of colorectal cancer and the prognosis of patients. The expression of CDC25B in 168 patients with colorectal cancer and 25 patients with adenoma, and normal colorectal mucosa from 20 individuals was assayed by immunohistochemistry (S-P method). The expression of CDC25B was not detected in adenoma and normal colorectal mucosa. The expression rate of CDC25B in colorectal cancer was 71.4%(120/168). The expression of CDC25B had a positive correlation with distant metastasis and the increase of CEA,while it had no relationship with the tumor stage, grade, lymph node metastases, gender, age or the size of tumor . The patients in whom expression of CDC25B was detected had a markedly low 5-year survival rate. The results suggested that expression of CDC25B in colorectal cancer might accelerate the transformation of cell cycle,which promoted metastasis to distant organ, indicating that the expression of CDC25B might play a role in the development of colorectal cancer. The expression of CDC25B was a risk factor of poor prognosis.

Objective To explore the cell-mediated immune function in patients with colon cancer undergoing minilaparotomy or laparoscopic assisted right hemicolectomy. Methods From January 2009 to August 2014, the colon cancer patients receiving right hemicolectomy were retrospectively analyzed. According to the operation mode, the patients were divided into minilaparotomy group and laparoscopic-assisted group. The clinical and pathological data was analyzed. Cell counts of total CD3, CD4, CD8, CD19 as well as NK cells in venous blood samples were compared between 1 day before surgery and postoperative days (POD) 1 and 5. Measurement data with normal distribution was compared using the t test or Q test. Count data was analyzed usingχ2 test or Fisher exact probability. Results There were 408 patients with colon cancer undergoing right hemicolectomy, 26 patients of whom were excluded. The remaining 382 patients were recruited in the research, which were divided into minilaparotomy group (182 cases) and laparoscopic-assisted group (200 cases). There was no significant difference in the age, gender, body mass index, TNM staging, histological type, blood loss, return of bowel function, tumor location, hospital stay and postoperative complications between the two groups (all P> 0.05). The operating time in minilaparotomy group [(131.53 ± 22.57) min] was shorter than that in laparoscopic-assisted group [(167.53 ± 22.04) min], and there was significant difference (t=15.76, P= 0.00). Compared with prior to surgery, cell numbers of CD3, CD4, CD8, CD19 and NK cells were lower on POD 1 and POD 5 (all P< 0.05), but there was no difference between minilaparotomy group and laparoscopic-assisted group (all P>0.05). Conclusion The minilaparotomy and laparoscopic-assisted right hemicolectomy have same effect on cellular immune function of patients with colon cancer.

BACKGROUND: The survival rate of articular chondrocytes is low after traditional cryopreservation,and great differences existed in chondrocytes from surface layer and deep layer,which easily result in graft degeneration and lead to surgery failure.OBJECTIVE: To establish rabbit allograft models of graded frozen articular cartilages with holes made before cryopreservation and to observe the effect of holed cryopreservation on the rabbit articular cartilages.METHODS: Osteochondral plugs taken aseptically from 2 months old rabbits were randomly divided into 3 groups: the experimental group,making holes(3 mm× 3 mm)in articular cartilages and graded freezing; non-hole graded freezing group,non-making holes and graded freezing; cryopreservation group: non-making holes and rapid freezing.The grafts were thawed and transplanted into the relevant articular cartilage defects of recipient rabbits.The grafts differences were observed by gross observation,histochemistry and immunohistochemistry staining.RESULTS AND CONCLUSION: The gross observation,histochemistry and immunohistochemistry staining of the experimental group were superior to the cryopreservation group.Though there were no significant differences between the non-hole graded freezing group and the experimental group,however,the experimental group enhanced the protective effect on cartilage tissue in the middle layer.The graded cryopreservation of articular cartilage gets an advantage over rapid cryopreservation.And the articular cartilage with holes could be preserved successfully in graded cryopreservation,which assures the survival and function of chondrocytes and slows down degrading process of the articular cartilage tissue after thawed and transplanted.

Objective To investigate the optimal b value of diffusion-weighted imaging (DWI)in predicting the grade of cerebral gliomas.Methods 38 patients with pathologically-proved brain gliomas (24 high-grade gliomas and 14 low-grade ones)were studied retrospectively.All patients received conventional MRI and DWI examination with three different b values (1 000 s/mm2 ,2 000 s/mm2 and 3 000 s /mm2 ).The signal features of the tumor on DWI with three different b values were evaluated and compared.The minimum ADC values of the tumors were calculated and compared between each other.Through drawing the ROC curve of different b values, the best diagnostic threshold was found.The sensitivity and specificity in predicting the grade of brain gliomas were assessed using Chi-square test.Results On DWI with b value of 3 000 s/mm2 ,91.6% (22/24)of high-grade tumors showed hyper-intensity, while 85.7%(12/14)of low-grade tumors presented hypo-intensity signals.Regarding hyper-intensity signals as diagnostic criterion for high-grade tumors,the sensitivity and specificity were 91.6% and 100% respectively.When the b value was similar,the minimum ADC value of high-grade glioma was significantly lower than that of low-grade glioma,and statistically significant differences in differentiating high-grade glioma from low-grade glioma existed among three b values (P <0.05).When the ADC 3 000 value<0.74×10 -3 mm2/s was regarded as a standard for the identification of high-grade and low-grade glioma,the sensitivity and specificity were 100% and 87.3%respectively.Conclusion DWI with high b value is more useful than standard moderate b value in preoperative grading the gliomas.When DWI with b value of 3 000 s/mm2 is used,the minimum ADC value will provide quantitative indicators in preoperatively precisely predicting grading glioma.
