OBJECTIVE To probe how to avoid the complication after intravenous infusion for the elders. METHODS The cause of the complication in infusion therapy for the elders with a total of 80 cases in the past three years was analyzed retrospectively. RESULTS Among the complications after intravenous infusion for 80 elders,leakage injury accounted for 47 cases(58.5%), and phlebitis accounted for 21 cases(26.8%),respectively. CONCLUSIONS As the elders′ blood vessel wall is very thin,the intravenous infusion often causes injury,the nurses should pay more attention to operating of intravenous infusion for the elders,observing regularly,and prolonging the time for pressing the pinprick after pulling out the dropper,in order to reduce the coming of injury.

Objective To study the expression and clinical significance of Survivin and PTEN in cervical carcinoma. Methods The expression of Survivin and PTEN in 60 cases of cervical carcinoma, 15 cases of CIN Ⅰ , 15 cases of CIN Ⅱ, 15 cases of CIN Ⅲ and 15 cases of normal cervical tissues were detected by immunohistochemical staining. Results The expression positive rates of Survivin were 86.67 %, 80.00 %,33.33 %, 20.00 % and 0, respectively, and those of PTEN were 21.67 %, 40.00 %, 80.00 %, 86.67 % and 100.00 % in cervical carcinoma, CIN Ⅲ, CIN Ⅱ, CIN Ⅰ and normal cervical tissues, respectively. The expression positive rates of Survivin were increased along with normal cervical epithelium, CIN Ⅰ, CIN Ⅱ,CIN Ⅲ and invasive carcinoma of cervix;while those of PTEN were inverse order.Compared with the expression positive rates of Survivin and PTEN protein in the CIN Ⅱ group, those in the CIN Ⅲ group had significant differences (P <0.01 and P <0.05, respectively). Expressions of Survivin and PTEN were correlated to the size of focus(P <0.05), the depth of tumor and pelvic lymphnode metastasis (P <0.05), but not to clinical staging, pathological types, pathological grading and age(P >0.05). There was a negative correlation between the expression of PTEN and Survivin in cervical carcinoma. Conclusion The expressions of Survivin and PTEN are correlated with invasion and metastasis of cervical carcinoma, and be related to clinical pathotology.Survivin and PTEN may play a important role in the formation, proliferation, differentuation and metastasis of cervical carcinoma. They may be used as markers of early diagnose, efficacy and prognosis evaluation.
