Object:To understand the situation of postpartum abuse and postpartum depression Method:This was a community-based face-to-face survey of a representative group of women who had a child aged 6 to 18 months in 32 communities of Tianjin, Liaoning, Henan and Shaanxi provinces between Nov 1, 2001 and February28, 2002 Totally 12044 subjects were found by stratified cluster sampling Results:The incidence of postpartum depression (according to result of Zung's self-rate depression scale for one week assessment during the interview) was 20 9%, while the rate of postpartum abuse was 8 3% Women often suffered abuses with many forms (physical, sexual and emotional maltreatment), and recurrently for a long time Among them, sexual abuse was the most frequent one Multiple logistic regression showed association between abuse and depression Conclusion:The incidences of postpartum depression and postpartum abuse are high Being abused has influence on depression

OBJECTIVETo identify contraceptive use behavior and its determinants among never married young women with an unwanted pregnancy and seeking pregnancy termination in Beijing.

METHODSA cross sectional study, adopting the Lawrence' PRECEDE-PROCEED model was conducted in 1999 in Beijing, China. A total of 306 unmarried young women, aged 18 to 24 years and requesting pregnancy termination, were face to face interviewed.

RESULTSOnly 13% of the young women insisted on contraceptive use, and almost an equal proportion occasionally or never used contraceptives (26% and 27%, respectively). Among 224 women who had contraceptive use during the past 12 months, the methods used most often were condom (49%), withdrawal (28%) and the rhythm method (16%). One of the most important reasons cited by 73 percent of women who had never used contraceptives was that they did not realize the risk of getting pregnant. The results of logistic regression analysis revealed that knowledge on contraception, boyfriend's approval of contraceptive use, perceived risk of getting pregnant, perceived availability of contraceptive services and discussion of contraception with boyfriend were important indicators of a young woman's contraceptive use behavior.

CONCLUSIONThese results indicate an urgent need to develop sex education on conception and contraception among young women and men. It is equally important to enhance young women's perception about the risk of unwanted pregnancy and the complications of induced abortion. Promotinga men's cooperation and participation in contraceptive use as well as strengthening communication on contraception between young women and their partners is essential.

Objective: To explore the epidemiologic characterization of high-risk human papillomavirus (HR-HPV) infection and genotype distribution of HR-HPV among women in rural areas of China. Methods: This study used multiple layers of stratified cluster random sampling method. During January to December in 2014, 117 counties of 27 provinces were selected as the HPV test screening pilot project counties. The women aged 35-64 years with rural areas Hukou in these project counties were selected as the study subjects. A total 457 799 women received HPV DNA test. Among them, 118 237 women from 32 counties in 11 provinces received qualified HPV DNA test by fluorescent PCR to detect HPV genotypes. Results: Among 118 237 rural women, the overall HR-HPV positive infection rate was 7.8% (9 249/118 237). The infection rate increased with age and reached an infection peak at the 60-64 age groups (9.9%, 831/8 394). The HR-HPV positive infection rate in western regions (6.9%, 2 144/31 130) was statistical significantly lower than in central regions (8.2%, 1 894/23 023) and eastern regions (8.1%, 5 211/64 084) (χ²=51.46, P<0.001). Among 9 249 women with specific genotypes of HR-HPV, 6 496 (97.6%) cases were infected with single HR-HPV type, and 163 cases (2.4% ) were infected with multiple types. HR-HPV type 52, 16 and 58 were the most common infection types in rural areas of China. The single infection rates were 20.9% (1 355/6 496), 18.7% (1 215/6 496), and 11.2% (725/6 496), respectively. The multiple infection rates were 47.2% (77/163), 17.8% (29/163), and 18.4% (30/163), respectively. Conclusion The HR-HPV positive infection rate in rural areas of Chinese woman was 7.8%, western region has lower infection rate compared with central and eastern regions. HPV 52 was first of the most common genotypes in rural areas of China.

OBJECTIVETo find out the occurrence of cesarean section (CS) and related factors among child-bearing women in China.

METHODSThe survey was conducted during October, 2010 in 40 counties selected from 30 provinces. Size proportional sampling method was employed in sampling. A face to face questionnaire investigation was conducted among 8 420 women who experienced pregnancies from 1978 to 2010. Information on demographic characteristics, history of pregnancy and birth were obtained, and related factors of CS occurrence were analyzed.

RESULTSA total of 11 440 living births have been given by 8 420 women, and 1 725 CS happened. As the time goes on, there is a growing trend of CS occurrence, from 2.0% (14/701) in 1978-1985 to 36.6% (813/2 224) in 2006-2010, and there is a most fast increase from 2001 to 2010. CS rate in Mid-China (42.3%, 257/608) is the highest from 2006 to 2010. And also, the rate of CS requested by the pregnant women or their family members was increasing year by year, from 14.3% (2/14) in 1978-1985 to 43.7% (255/813) in 2006-2010. Women who were above 25 years old (21.4%, 960/4 485) , with an education degree of high school or above (24.5%, 568/2 317), engaged in nonagricultural work (22.4%, 663/2 956), living in eastern provinces of China (18.6%, 757/4 074), fetal malposition (45.4%, 247/544) , with a heavier birth weight(4 000 gram or above) (36.5%, 175/479) , have accepted B ultrasound exam (18.8%, 1 633/8 687) with an increasing of blood pressure (28.0%, 172/614) and convulsion experiences (24.8%, 131/528) during pregnancy were more likely to have CS.

CONCLUSIONThe CS rate among child-bearing women in China was rather high, and was related with factors of demographic characteristics(age of childbearing, education, vocation, residence) and some medical factors(neonatal weight, having accepted B ultrasound exam, fetal malposition, an increase of blood pressure and convulsions during pregnancy).

Objective:To evaluate the effectiveness and quality of ultrasound-based (BUS) process optimization in breast cancer screening.Methods:The program collected the first to fourth quarterly breast cancer screening statistic data and case report data from 30 provinces, autonomous regions and municipalities in 2015 by the online report system of national key service program of women and children′s public health. The call rate, mammography (MG) subsequent screen rate, biopsy rate, detection rate, early diagnosis rate, carcinoma in situ rate, missing detection rate, false positive rate and positive predictive value (PPV) of breast cancer were calculated.Results:A total of 1 501 753 rural women attended the BUS process optimization screening. The nationwide recall rate was 3.01%(45 156/1 501 753), and in the eastern and central area were 3.41%(17 173/503 130) and 3.56%(14 499/407 739), respectively, higher than 2.28% (13 484/590 884) of western area ( P<0.05). The nationwide MG subsequent screen rate was 2.78%(41 694/1 501 753), and in the eastern and central area were 3.19%(16 036/503 130) and 3.29% (13 421/407 739), respectively, higher than 2.07%(12 237/590 884) of western area ( P<0.05). The nationwide biopsy rate was 0.23%(3 462/1 501 753), and in the central area were 0.26%(1 078/407 739), respectively, higher than 0.21%(1 247/590 884) of western area and 0.23% (1 137/503 130) of eastern area ( P<0.05). The nationwide biopsy PPV was 37.00%(1 281/3 462). The biopsy PPV of eastern area was (34.30%, 390/1 137), lower than 39.33% (424/1 078) of central area ( P<0.05). A total of 1 281 cases of breast cancer were detected, the detection rate was 0.85‰(1 281/1 501 753), and the detection rates of central area was 1.04‰ (424/407 739), higher than 0.79‰(467/590 884) of western area and 0.78‰(390/503 130) of eastern area ( P<0.05). The BUS initiate screening positive rate from detected breast cancer cases was 96.96%(1 242/1 281), the MG subsequent screening positive rate was 2.42%(31/1 281). The nationwide early diagnosis rate was 85.25%(1 092/1 281), and in the eastern and central areas were 87.95%(343/390) and 88.21%(374/424), higher than 80.30%(375/467) of western area ( P<0.05). The screening rate of on or above stage Ⅱ breast cancer in eastern area was 55.64%(217/390), lower than 64.62%(374/424) of central area and 62.31%(291/467) of western area. The missing detection rate was 0.62%(8/1 281) and false positive rate was 1.20%(17 528/1 464 149). Conclusions:The BUS process optimization of breast cancer screening scheme is reasonable and applicable to China rural women. The effectiveness and quality of eastern area are superior to those of central and western area.

Objective To analyze the reported data of national rural cervical cancer screening project from 2012 to 2013 and to evaluate the project implementation condition. Methods Data of the national breast carcinoma and cervical cancer (two-cancer) screening project for rural women were collected from the online report system of key women and children's public health service programs.The screening items included: preliminary screening of cervical lesions (cervical cytology, using Traian Bethesda System (TBS) or Pap grading for classification and reporting), acetate/iodide staining (VIA/VILI), colposcopy, histopathological examination, and pathological diagnosis. The study collected the quarterly reported data from 1 183 counties of 30 provinces in 2014 and 1 130 counties of 30 provinces in 2013. Chi-square test was used to test the difference of positive detection rate, as well as precancerous cervical lesions, and cervical cancer detection rates among difference preliminary screening methods in 2012 and 2013. Results In 2012 and 2013, the number of cervical cancer screening was 10 621 482 and 10 321 835. The percentage of using ThinPrep cytological test as the screening method was 77.17%(n=8 196 627) and 77.07%(n=7 954 949) in 2012 and 2013, respectively. Among these ThinPrep cytological tests in these two years, 65.49%(n=5 368 194) and 71.67% (n=5 701 033) used TBS report system. The abnormality rate of colposcopy increased from 27.29% (170 063/623 161) to 31.15% (203 397/652 935) (χ2=2 295.94, P<0.001). The abnormality rate of histopathology test increased from 19.54% (37 992/194 394) to 35.43% (59 004/166 518) (χ2=11 523.58,P<0.001). All together, 27 341 cervical cancer or precancerous lesions have been detected in these two years. The detection rate of invasive cervical cancer increased from 18.02/100 000 in 2012 to 19.71/100 000 (χ2=7.90, P=0.005) in 2013 and that of precancerous lesions rose from 106.85/100 000 to 119.26/100 000 (χ2=70.82, P<0.001). The early detection rate was 89.60% (11 883/13 263), and 89.57%(12 609/14 078), respectively in 2012 and 2013. In these two years, the rank of the detection rate of each cervical lesion were CIN1, CIN2, CIN3, invasive carcinoma, adenocarcinoma in situ, and microinvasive carcinoma, from the highest rate to the lowest rate. Conclusion The program has achieved certain screening effect and the screening method has been improved. However, the quality of colposcope and histopathology should be enhanced.

Since December 2019, a novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) outbreak has occurred in Wuhan, Hubei Province, and the epidemic situation has continued to spread. Such cases have also been found in other parts of the country. The spread of the novel coronavirus pneumonia epidemic has brought great challenges to the clinical practice of thoracic surgery. Outpatient clinics need to strengthen the differential diagnosis of ground glass opacity and pulmonary plaque shadows. During the epidemic, surgical indications are strictly controlled, and selective surgery is postponed. Patients planning to undergo a limited period of surgery should be quarantined for 2 weeks and have a nucleic acid test when necessary before surgery. For patients who are planning to undergo emergency surgery, nucleic acid testing should be carried out before surgery, and three-level protection should be performed during surgery. Patients who are planning to undergo emergency surgery in the epidemic area should be confirmed with or without novel coronavirus pneumonia before operation, and perform nucleic acid test if necessary. Surgical disinfection and isolation measures should be strictly carried out. Among postoperative patients, cases with new coronavirus infection were actively investigated. For the rescue of patients with novel coronavirus infection, attention needs to be paid to prevention and treatment and related complications, including mechanical ventilation-related pneumothorax or mediastinal emphysema, and injury after tracheal intubation.
