Objective To evaluate the expression and function of mammalian target of rapamycin (mTOR) and its substrate kinase P70S6K in mTOR/P70S6K signal pathway in cervical carcinogenesis. Methods The expression of mTOR and P70S6K in normal cervix uteri or cervical cancer was detected by the immunohistochemistry and RT-PCR methods. Results Compared to those in normal cervix uteri, both mRNA and protein of mTOR/P70S6K in cervical carcinomas were significantly increased (P<0.05). There was a positive correlation between mTOR gene and P70S6K gene expression in cervical cancer (r=0.746, P<0.001). Conclusion High expression of mTOR and P7OS6K may play an important role in the pathogenesis and development of cervical cancer.

Objective To study the incidence of malposition of catheter at different body positions during the operation of peripherally inserted central catheter (PICC),and then select the optimum position to increase the success rate of insertion. Methods 155 patients were randomly divided into the horizontal position group (55 cases),the semi-reclining position group (49 cases) and the sitting position group (51cases).They all used chest X-ray to conffirm the position of top end of the catheter after insertion and then comparing the incidence rate of malposition of catheter among three groups. Results After insertion,11 patients' catheters were found malposition.Among them,8 patients were in the semi-reclining position group (incidence rate 16.3%),2 patients were in the horizontal position group (incidence rate 3.6%) and only one patient was in the sitting position group (incidence rate 1.9% ).Incidence rate of catheter malposition in the semi-reclining position group was significantly higher than other two groups. Conclusions The best position for PICC is the horizontal position.If the patient has expiratory dyspnea or need to adjust the malposition catheter,sitting position can be used.Semi-reclining position should be avoided in the operation of PICC.

Objective To explore the incidence and pathologic feature of patients with thyroid carcinoma treated at the First Hospital of Jilin University. Methods From January 2000 to July 2010,clinicopathologic data of 1018 patients with thyroid carcinoma treated in the First Hospital of Jilin University were retrospectively analyzed. Results The cases of thyroid carcinoma between 2008 and 2010 were more than 73% higher than that in the preceding 8 years. Cancer cases from January 2009 to July 2010 were more1018 cases reviewed, 976 cases were clearly classified pathologically. Papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma were present in 897 (91.91%), 43(4. 41% ), 22(2. 25% ) and 6(0. 61% ) cases respectively. Of the 1018 cases reviewed,804 cases were recorded with or without lymphnode metastasis. The rate of lymphnode metastasis of male and female patient were 39. 24% and 28. 64% respectively and the difference was significant( χ2 = 6. 71 ,P <0. 05). The rate of lymphnode metastasis of age <45 years and age ≥45 years were 37.65% and 23. 26%respectively and the difference was significant ( χ2 = 19. 54, P < 0. 05 ). Conclusions In the past ten and a half years, the number of the thyroid carcinoma patients treated in the First Hospital of Jilin University increased year by year. The increase of papillary thyroid carcinoma was the most obvious. Thyroid carcinoma was more common among females. The peak incidence age of males and females was 30 -59. The rate of lymphnode metastasis of males was larger than that of females. The rate of lymphnode metastasis of age <45years was larger than that of age≥45 years.
