Purpose To investigate the expression of the interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-alpha;) in epiretinal membranes(ERM) of eyes with proliferative vitreoretinopathy(PVR). Methods Nineteen epiretinal membranes were obtained form eyes undergoing vitrectomy for retinal detachment complicated with PVR and observed by immunohistochemical methods. Results Expression of IL-6 and TNF-alpha; were observed in 12 and 15 membranes respectively with positive staining mostly in extracellular matrix of epiretinal membranes.Only one membrane showed positive to IL-6 intracellularly,and expression for IL-6 and TNF-alpha; simultaneously in membranes. Conclusion The findings indicate that IL-6、and TNF-alpha;might be involved in the development of PVR. (Chin J Ocul Fundus Dis,1998,14:219-221)
Objective To explore the effect of pain management by anesthesia nurses on labor analgesia. Methods A total of 100 parturient women in the Affiliated Hospital of North China University of Science and Technology between July and August 2015 were randomly divided into two groups: analgesia group and control group with 50 in each. Both two groups accepted labor analgesia routine maternity nursing. Analgesia group accepted maternal perinatal term pain management in addition to the routine nursing. Then we compared degree of pain during the production process, labor time and perineal injury between the two groups of women. Results The number of women with a labor pain degree of 0-Ⅲ in the analgesia group was respectively 36 (72%), 12 (24%), 2 (4%) and 0 (0%), and the number in the control group was respectively 23 (46%), 17 (34%), 8 (16%), and 2 (4%). The above difference between the two groups was statistically significant (Z=–2.908, P =0.004). The number of women with intact perineum, perineal injury of lateral and median cut, and Ⅰ-Ⅲ degree laceration in the analgesia group was respectively 31 (62%), 7 (14%), 8 (16%), 4 (8%) and 0 (0%); and the number in the control group was respectively 21 (42%), 12 (24%), 10 (20%), 7 (14%) and 0 (0%), also with significant difference between the two groups (Z =–2.028, P =0.043). The first and second labor stage of the analgesia group was (462.32±101.27) and (63.58±10.38) minutes, and was (568.27±113.28) and (76.92±11.24) minutes in the control group, with significant differences between the two groups (P<0.001). There was no statistically significant difference between the two groups in the third labor stage (5.78±3.02) and (5.97±2.96) minutes, (P=0.654). Conclusions The implementation of pain management by anesthesia nurses on labor analgesia can significantly reduce maternal labor pain, shorten the time of labor, and the condition of the perineal injury is mild and easily acceptable. It is worthy of clinical promotion.
