Objective To evaluate the values of visual inspection with acetic acid( VIA) and human papillomavirus( HPV) and thinprep cytology test( TCT) in the screening of cervical cancer.Methods VIA,HPV test and TCT in 946 women was conducted.Cervical biopsy or endocenical curettage( ECC) was performed in VIA positive women or HPV positive women or TCT positive women. The pathologic outcome was as the gold standard,and the out come more and equal to cervical intraepithelial neoplasia( CIN) Ⅱ were identified as positive.Results There was no significant difference among three groups in sensitivity rate( 73.l％,96.2,88.5％ ) and negative predictive value ( 99. 1％ ,99.9％ ,99.7％ ) ( all P ＞ 0.05 ).The specificity rate (97.5％ ) and positive predictive value ( 50.O％ ) of TCT was better than those of HPV ( 93.5％,29.4％ ),and HPV was better than those of VIA( 87.0％,13.7％ ),and the difference had statistifical significance among three groups ( x2 =71.34,26.00,22.17,8.28,all P ＜ 0.05 ).Conclusion Although the rate of missed diagnosis and misdiagnosis rate was higher than that of HPV and TCT,but VIA seems to be appropriate methods in the screening of cervical cancer owing to its low price.

Objective To improve patient postoperative comfort of vitrectomy with tamponnade in the prone position, design a new prone position headrest to reduce complications caused by improper body position and observe its clinical effect. Methods According to the postoperative position of the patients, 360 cases were collected. The patients were divided into the control group and the observation group with 180 cases of each group. Observation group was treated with the new prone position headrest nursing, control group were treated with routine prone position. The comfort of patients, postoperative adverse reactions, success rate of retina reattachment were observed. Results According to simplified comfortable situation scale, physiological, psychological, social culture and environment of each individual score respectively was (2.74±0.21), (3.54±0.29) , (3.25±0.23), (3.36±0.27) points in observation group and (2.30± 0.19), (2.92±0.31), (2.93±0.26), (2.79±0.30) points in control group, and there were significant differences (t=12.368-20.845, all P<0.05). The daily posture duration in postoperative first time and 5 days was respectively (220.00±25.08), (1008.00 ± 20.32) min in observation group and (85.00±28.07), (650.00± 30.12) min in control group, and there were significant differences(t=48.117, 133.194, all P<0.01). The incidence of corneal edema, conjunctival congestion, water turbidity in observation group were lower than those in control group at 4 weeks after surgery, and there were statistically significant difference (U=6.308,8.130, 6.875, P < 0.01). The incidence of high intraocular pressure, recurrent retinal detachment rate and reduction rate in observation group were lower than those in control group at 4 weeks after surgery, and there were statistically significant difference (χ2=9.000, 10.540, 11.770, P < 0.01). Conclusions The new prone headrest can effectively improve the resection of vitreous body with tamponade patients in comfort, ensure the operation effect.
