To assess the current prevalence of and risk factors for infertility among couples reproductive age in China. Population-based cross-sectional study. We approached 25 270 eight provinces/municipalities, whom 18 571 (response rate 74%) were interviewed. Couples living together married more than 1 year, female spouse was 20-49 years old. Women via telephone face-to-face conversation to complete standardised structured questionnaire by trained interviewers. Prevalence infertility. Among women...
<h3>Importance</h3> Presence of thyroid autoantibodies in women with normal function is associated increased risk miscarriage. Whether levothyroxine treatment improves pregnancy outcomes among undergoing vitro fertilization and embryo transfer (IVF-ET) unknown. <h3>Objective</h3> To determine the effect on miscarriage IVF-ET who had tested positive for autoantibodies. <h3>Design, Setting, Participants</h3> An open-label, randomized clinical trial involving 600 antithyroperoxidase antibody...
Polycystic ovary syndrome (PCOS) has become a major international public health concern. However, because of controversy about the diagnostic criteria and patient selection, estimates its absolute prevalence change with time vary greatly.We conducted two consecutive nationwide epidemiological surveys PCOS in representative samples reproductive-aged women China 2010 2020. Face-to-face interviews were performed by trained interviewers each survey. All participants completed questionnaire...
Transformer winding deformation is common among all sorts of transformer failures. Cumulative can eventually burgeon into catastrophic faults and result in entire network outage. It possible to detect the early signs with continuous online monitoring transformer. However, frequency response analysis (FRA) considered be a useful accurate tool for sufficient detection. This paper aims at proposing novel diagnostic system power based on FRA. In order realize winding, uses capacitive coupling...
Objective To estimate the proportion of married women in China who intend to become pregnant given country's pronatalist population policy and investigate fecundity, with an emphasis on influence socioeconomic factors.Methods A nationally representative survey 12 815 aged 20 49 years (mean: 36.8 years) was conducted during 2019 2020.All completed questionnaires, 10 115 gave blood samples 11 710 underwent pelvic ultrasound examination.Fertility intention desire or intent combined engagement...
We developed a prognostic model to evaluate the overall survival (OS) and progression-free (PFS) of patients with unresectable hepatocellular carcinoma (u-HCC) treated Hepatic arterial infusion chemotherapy oxaliplatin, fluorouracil leucovorin (FOLFOX-HAIC). This was based on retrospective study u-HCC FOLFOX-HAIC (oxaliplatin 130 mg/m2, 400 bolus mg/m2 day 1, 2,400 for 23–46 h, once every 3–4 weeks). divided into training cohort validation cohort, used LASSO regression construct models,...
Abstract The roles of ethnicity and migration in determining the size human prostate zones during midlife were explored. Prostate was measured by planimetric ultrasound 163 men residing Sydney who either Australian non-Chinese (AR; n = 116) or Chinese migrants (ACM; 47) had lived Australia for a median 7.3 yr (range, 0.2–25 yr). These compared with China (CR; 210). Central total volumes estimated single observer using same equipment at both sites. After adjustment age, central significantly...
Winding deformation is a common problem that takes place within operating power transformers due to various internal and external conditions. Due their progressive nature, winding deformations should be detected rectified as soon they emerge. Unfortunately, the only reliable technique detect such faults at this stage frequency response analysis which conducted offline. This has motivated researchers propose alternative techniques transformer incipient core in real time. One of promising...
The cesarean section (CS) rate has risen globally during the last two decades. Effective and feasible strategies are needed to reduce it. aim of this study was assess CS change after a two-stage intervention package that designed overall in Guangzhou, China.This implemented by Health Commission Guangzhou Municipality 2 stages (October 2010-September 2014 October 2014-December 2016) included programs for population health education, skills training healthcare professionals, equipment...
To determine the normative cut-off value for free androgen index (FAI) among reproductive-age women in China.Cross-sectional, population-based study.A multistage systematic cluster random sampling 16 communities from two rural and city regions.A total of 1526 were randomly selected a representative sample 3009 aged 20-45 years general population southern China. Among these women, 444 subjects without known factors affecting levels as reference group.Subjects underwent physical examination,...
Polycystic ovary syndrome (PCOS) progression involves abnormal insulin signaling. SH2 domain-containing adaptor protein (Lnk) may be an important regulator of the signaling pathway. We investigated whether Lnk was involved in resistance (IR). Thirty-seven women due to receive laparoscopic surgery from June 2011 February 2012 were included gynecologic department Sun Yat-Sen Memorial Hospital, University. Samples polycystic and normal tissues examined by immunohistochemistry. Ovarian cell...
Triggered vacuum switch (TVS) is significant in the field of pulse power technologies, especially high application. Particularly, rise-time trigger important for paralleled TVSs which are frequently used to increase peak current. Trigger source based on transformer and solid state has good reliability low jitter, thus, design a fast-rise-time solid-state crucial parallel connected TVS. The work presented here extends art area generator. This paper introduces procedure closed magnetic core...
Abstract Background Polycystic ovary syndrome (PCOS) is currently considered to have a peri-adolescence onset and continuously influence the reproductive metabolic health of patients, while diagnostic criteria among adolescent population haven’t been universally unified till now. This survey seeks preliminarily evaluate prevalence PCOS in tenth grade schoolgirls Guangzhou area under NIH analyze clinical features adolescents with PCOS. Methods The cross-sectional epidemiological was carried...
In the present study, we evaluated impact of sperm origins and concentration on clinical outcomes intracytoplasmic injection (ICSI) cycles. A total 1201 ICSI cycles were retrospectively analyzed for male azoospermia or oligozoospermia between January 2015 December in Peking University Third Hospital. Patients divided into three groups (Group 1 vs Group 2/3; surgically extracted ejaculated sperms): included 343 2 388 semen with <5 × 106 ml-1 (severe group). 3 470 5 15 (mild Fertilization...
