Chinese Journal of Minimally Invasive Surgery 2017;17(2):155-158
Objective To investigate the clinical characteristics of postmenopausal patients with cervical intraepithelial neoplasia ( CIN) gradeⅡ/Ⅲand cervical cancer . Methods A retrospective analysis was made on the clinical characteristics of 57 cases of postmenopausal patients who were diagnosed as CIN grade Ⅱor above from January 2014 to September 2015.Their age ranged from 49 to 77 (58.2 ±5.6) years old, and the time of menopause ranged from 1 to 36 (9.4 ±6.9) years. Results ①In postmenopausal women with CIN Ⅱ/Ⅲ and cervical cancer, only about 1/5 (11/57, 19.3%) had clinical complaints, and nearly 2/3 (36/57, 63.2%) had smooth cervical appearance .②There were 36 cases of high-risk human papillomavirus ( HPV) (36/39, 92.3%), 20 cases of single HPV16 infection (20/36, 55.6%), 7 cases of HPV16 type and other high-risk HPV infection (7/36, 19.4%), and 9 cases of other types of high-risk HPV infection (9/36, 25.0%).③The positive rate of high-risk HPV was 92.3%(36/39) and the HPV16 positive rate was 69.2% (27/39).TCT examination showed a positive rate of high grade squamous intraepithelial lesion (HSIL) of only 29.6% (16/54), with significant difference (χ2 =6.686 and 14.286, P =0.010 and 0.000, respectively). Conclusions Postmenopausal women with cervical lesions usually have no obvious clinical symptoms . Gynecological examination alone is difficult to judge whether the cervical lesions exist .Strict cervical lesions screening is particularly important .

Chinese Journal of Practical Nursing 2016;32(19):1466-1469
Objective To explore the best turn lateral position angle of the patients with stroke in acute phase. Methods 100 patients with stroke in acute phase weredivided into five groups according to 15 ° ,30 ° 45 ° , 60 ° , 90 ° turn lateral position angle separately and then observed the skin temperature of good location of pressure ulcers of the patients before and after turning over 2 h. The changes of blood pressure, heart rate and the finger tip pulse oxygen saturation were recorded within the turn over 2 hours. Results The skin temperature, blood pressure, heart rate, blood oxygen saturation among the groups had no statistical significance (P>0.05) in the difference turn angle of lateral position.The skin temperature, blood pressure, heart rate, blood oxygen saturation between the groups had no statistical significance (P>0.05) in the same turn angle of lateral position.Conclusions Five different turn lateral position angle have no obvious difference on the vital signs and the skin temperature in patients with stroke in acute phase. It is suggested to adopt the turn lateral position angle of less than 90° from the perspective of biomechanics and patients′comfort.
