Objective To explore relationship of the anesthetic risks and intraoperative complications.Methods Preoperative anesthetic risks were assessed with Hussman's method from May 2015 to May 2016 in 2 494 surgical patients, including 1 462 males and 1 032 females.Intraoperative data and complications were tracked and recorded.Results Three hundred and thirty-six intraoperative complications occurred, accounting for 13.47% of total patients.The cardiovascular complications were a major intraoperative complications, accounting for 80.7%.2 494 patients were graded respectively into risk grade 1 with 1 540 (61.75%), grade 2 with 660 (26.46%), grade 3 with 202 (8.10%), grade 4 with 80 (3.21%) and grade 5 with 12 (0.48%).The incidence of complications were 112 (7.28%), 82 (12.42%), 82 (40.59%), 50 (62.50%) and 10 (83.33%) respectively.The sensitivity of prediction was 33.33%, 24.40%, 24.40%, 14.88% and 2.78%;the specificity 33.76%, 73.26%, 94.44%, 98.61% and 99.91%;and the accuracy 33.76%, 66.64%, 85.01%, 87.33% and 86.85%, respectively, in patients with risk grade 1, 2, 3, 4 and 5.Conclusion Hussman's method of anesthetic risks well predicts the intraoperative complications.

Objective To investigate the constitutive characteristics and the change trend of gynecologic malignant tumors in hospitalized patients in Guangxi Zhuang Autonomous Region over the recent 20 years.Methods Clinical data of 8009 in-patients who suffered from gynecologic malignant tumors in 23 hospitals from 1985 to 2004 in Guangxi Zhuang Autonomous Region were analyzed,with respect to the tumor types and change trend.Results(1)The leading 4 types of malignant tumors were cervical cancers, ovarian cancers,endometrial cancers,and malignant trophoblastic tumors according to the constitutive ratios of the tumors.The constitutive ratio of cervical cancer patients rose year by year,from 17.48% during the 1985-1989 period to 49.25% during the 2000-2004 period(P0.05).(2)The occurring age of cervical cancers became younger obviously,from≥60 years old dropped to

Objective: To understand the relations between high risk sexual behavior and HIV infection among MSM in ways of finding male partners in Ningbo. Methods: A cross-sectional study was conducted in Ningbo between April and November in 2018. Data related to socio-demographics, ways of finding male partners, adoption of gay apps and sexual behaviors were collected by snowball method. Blood samples were drawn for HIV antibody testing. Classified data was evaluated by chi-square test. Related factors on HIV infection were analyzed by multivariate logistic regression. Results: A total of 735 participants were included in this study. Ways of finding male partners would through gay apps (60.8%, 447/735), QQ/Wechat (32.3%, 237/735) and gay-places (6.9%, 51/735). Related information on high risk sexual behavior and HIV infection among gay apps users were found as: 16.8%(75) had sexual behavior once per week in the past 6 months, 41.8% (187/447) had multiple sexual partners, 12.1% (54/447) had unprotected anal intercourse in the last time, 52.3% (234/447) having had unprotected anal intercourse in the past 6 months. The overall HIV prevalence rate was 12.1%(54/447). Among the HIV cases who got infected within the two years, 68.6%(24/35) of them had used gay apps for less than two years. Results from the, multivariate logistic regression analysis showed that gay apps users were more susceptible to infected HIV than those who used the QQ/Wechat (OR=3.03, 95%CI: 1.30-7.07). Conclusions Gay apps was popularly known among the Ningbo MSM, and was associated with the high risk sexual behaviors and HIV infection. HIV control and prevention programs should be strengthened in the MSM population who used the gay apps. Related surveillance and intervention programs for MSM, who use the gay apps, need to be further reinforced.
