Background: Female sexual dysfunction (FSD) is a highly prevalent and often underestimated problem. However, large-scale, population-based epidemiological surveys of FSD are scarce in China. The present study was conducted to evaluate the prevalence and the potential risk factors of FSD across a selection of social groups in Beijing, China, based on the Female Sexual Function Index (FSFI). Methods: A cross-sectional study based on the multiple-stage cluster sampling was performed with adult women throughout the Dongcheng and Shunyi districts of Beijing. The Chinese version of FSFI was used, as well as questions on demographic characteristics, the disease-related context, and social relationships. Results: A total of 6000 consecutive women entered this study, with an actual response from 5024 women, corresponding to a response rate of 83.7%. A total of 4697 (78.3%) questionnaires were effective. The prevalence of adult FSD in Beijing was 2973 (63.3%) using a score of 26.55 as the boundary value, whereas the total mean FSFI score was 23.92 ± 6.37. However, 1423 (30.3%) women did not seek help. By multivariate logistic regression analysis, the possible potential risk factors included age (odds ratio [OR] = 1.051), dissatisfaction with the spouse’s sexual ability (OR = 3.520), poor marital affection (OR = 2.087), spouse sexual difficulties (OR = 1.720), dissatisfaction with married life (OR = 1.476), living in a rural area (OR = 1.292), chronic pelvic pain (OR = 1.261), chronic disease (OR = 1.534), previous pelvic surgery (OR = 1.605), vaginal delivery (OR = 2.285), lower education (OR = 3.449) and postmenopausal (OR = 3.183). Conclusions: As suggested by the FSFI scores, female sexual problems are highly prevalent in Beijing. Dissatisfaction with the spouse’s sexual ability, poor marital affection, sexual difficulties of the spouse, dissatisfaction with the marriage, rural life, CPP, and postmenopausal were conceivable risk factors for FSD in Beijing women.

Background: Antiphospholipid syndrome (APS)-related immune factors are considered as an important cause of recurrent spontaneous abortion (RSA). Anticoagulant and anti-inflammatory treatments are believed to effectively improve adverse pregnancy outcomes by affecting the abnormal autoimmune response of the maternal-fetal interface. The aim of this study was to observe the clinical characteristics and treatment outcomes of anticoagulant regimens and anti-inflammatory plus anticoagulation regimens for APS-related RSA. Methods: APS-related RSA cases from September 2011 to September 2016 at Peking University Third Hospital were retrospectively analyzed. The patients were assigned to study group (anti-inflammation plus anticoagulation) and control group (simple anticoagulation). The incidence of repeat abortion, the incidence of placental dysfunction, the gestational weeks of pregnancy, and the mean weight of the fetus were observed. Results: The pregnancy and neonatal outcome indicators of the repeat pregnancy loss rate (11.11% vs. 22.70%), placental dysfunction-related diseases (6.35% vs. 15.60%), the mean birth weight of infants born after 24 weeks gestation (3152.41 ± 844.67 g vs. 2765.76 ± 816.40 g), full-term delivery weight (3456.28 ± 419.79 g vs. 3076.18 ± 518.79 g), the proportions of low birth weight infants (12.70% vs. 21.98%), and small for gestational age (6.35% vs. 14.18%) differed significantly between the study and control groups (all P < 0.05). The incidence of preterm delivery, term delivery, and stillbirth was not significantly different between the two groups, and there was no significant difference between the study and control groups in gestational age at birth (37.6 ± 3.3 weeks vs. 36.9 ± 3.2 weeks; P > 0.05). Conclusion: The anti-inflammatory and anticoagulation regimen is more effective than the simple anticoagulation regimen in the treatment of APS recurrent abortion.

Background: Ambient aerosol fine particulate matter (PM2.5) is associated with male reproductive toxicity in experiments and may have adverse effects in the female. However, studies evaluating the protective effects and precise mechanisms of aspirin, Vitamin C, Vitamin E, or ozone against toxic effects of PM2.5 are sparse. This study was conducted to investigate the possible protective effects and mechanisms of aspirin, Vitamin C, Vitamin E, or ozone on fertility in female mice treated with PM2.5. Methods: Eighty-four ICR mice were divided into six groups: control group, PM2.5 group, PM2.5 + aspirin group, PM2.5 + Vitamin C group, PM2.5 + Vitamin E group, and PM2.5 + ozone group. PM2.5 was given by intratracheal instillation every 2 days for 3 weeks. Aspirin, Vitamin C, and Vitamin E were given once a day by oral gavage for 3 weeks, and ozone was administered by intraperitoneal injection once a day for 3 weeks. The levels of anti-Müllerian hormone (AMH), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and 8-hydroxy-2’-deoxyguanosine (8-OHdG) were measured using enzyme-linked immunosorbent assay.Western blotting analysis was used to analyze the expressions of Bcl-2, Bax, and caspase-3 in ovaries. Changes in histological structure were examined by light microscope and electron microscopy was used to detect ultramicrostructure. Results: The results demonstrated that PM2.5 decreased AMH levels (P < 0.001); however, aspirin (P < 0.001), Vitamin C (P < 0.001), Vitamin E (P = 0.001), and ozone (P = 0.002) alleviated the decrease. Changes of IL-6, TNF-α, 8-OHdG, Bax/Bcl-2, and caspase-3 in PM2.5 group were increased compared to control group (P < 0.001), while in PM2.5 + aspirin, PM2.5 + Vitamin C, PM2.5 + Vitamin E, and PM2.5 + ozone groups, they were statistically decreased compared to PM2.5 group (P < 0.001 or P < 0.05). Conclusions: PM2.5 cause the damage of ovaries, and aspirin, Vitamin C, Vitamin E, and ozone antagonizes the damage. The protective mechanism is probably due to its ability to blunt the inflammatory and oxidative stress caused by PM2.5, which subsequently suppressing the expression of apoptotic regulatory protein and reducing the incidence of ovary apoptosis.

Background: Atrial AutoCapture™ (ACap™) was a new technological development that confirmed atrial capture by analyzing evoked response (ER) with a new method – paced depolarization integral ER detection – and optimized energy output to changes in the stimulation threshold. The purpose of this study was to evaluate the clinical performance of ACap™ function. Methods: This was a prospective, observational, nonrandomized two-center study. Between November 2008 and August 2014, 102 patients were enrolled from two different institutions. Data were collected by case report forms at enrollment, hospital discharge, and in-office follow-ups scheduled at 1, 2, 3, 6, and 12 months postimplantation. Results: Ambulatory ACap™ function started to become available for 20.6% of patients at 1 day, then progressed to 30.4% at 7 days, 38.6% at 1 month, 41.6% at 2 months, 47.5% at 3 months, 53.5% at 6 months, and 63.4% at 1 year. The cause of the unsuccessful attempts to perform ACap™ threshold was ER/polarization <2:1. Availability for SD, BND, and HOCM indications had shown better results than AVB indication. For SD indication cases, feasibility was significantly better for SD with paroxysmal atrial fibrillation (pAF) than SD without pAF (78.4% vs. 35.0% at 1 year, n = 71, P < 0.001). At each stage of the clinical follow-ups, there had been a strict correlation between ACap™ measurements and those conducted manually with P < 0.001 (n = 299). Conclusions: It has been concluded that ACap™ function was safe and effective to confirm atrial threshold and reduce energy output automatically. ACap™ function is unavailable for some patients at early stages of the implantation; however, availability has been progressively increasing during follow-up.

Background: It is currently believed that triple oral antithrombotic therapy in patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI) should be recommended if there are no contraindications. However, selecting triple therapy for AF patients undergoing PCI is still challenging when bleeding risk is considered. This study aimed to investigate the current use of oral anticoagulants (Vitamin K antagonists [VKA]) and perform prognostic analysis in real-world patients with AF undergoing coronary stenting. Methods: A total of 276 consecutive coronary artery disease (CAD) patients with or without AF undergoing coronary stenting were retrospectively evaluated and analyzed. The univariate and multivariate analyses were conducted to explore the current use of VKA and prognosis of patients with AF undergoing coronary stenting. The primary end-point was composite of all-cause death, nonfatal recurrent myocardial infarction, stroke, serious bleeding events, unplanned repeat revascularization, and worsening heart failure at 12-month follow-up after coronary stenting. Results: AF patients undergoing coronary stenting have more clinical concomitant diseases. Only 9.0% AF patients after coronary stenting received triple antithrombotic therapy (VKA, aspirin, and clopidogrel) at discharge. AF was independently associated with increased risk of the 12-month composite end-points (relative risk = 5.732, 95% confidence interval 1.786–18.396, P = 0.003). Conclusions: In real-life AF patients undergoing coronary stenting, guideline-recommended VKA was less used. AF patients had adjusted worse prognosis during 12-month follow-up after discharge. It is of utmost importance to improve the current status of oral anticoagulants use.

Background: Primary angle-closure glaucoma (PACG) is a common eye disease and a common cause of blindness. Inappropriate medical decisions severely affect the prognosis. This study investigated decision-making under risk in PACG patients. Methods: Thirty patients with first acute attack of PACG before surgery and thirty healthy controls were included in the study. Decision-making under risk was evaluated with the game of dice task (GDT). The results of Eysenck Personality Questionnaire (EPQ) and GDT between PACG patients and healthy controls were compared. Results: Risky decisions in PACG patients were more than those in healthy controls as measured by mean score of GDT (12.47 ± 5.72 vs. 4.33 ± 3.30, P < 0.001). Higher neuroticism score in EPQ was found in PACG patients compared to healthy controls (14.97 ± 3.93 vs. 9.90 ± 4.49, P < 0.001). Neuroticism scores in EPQ were associated with decision-making performance (r = 0.417, P = 0.001). Conclusions: Neuroticism positively correlated with risky decisions. Decision-making might be influenced by neuroticism. Future studies will show whether therapy compliance will be improved by emotional management and psychological intervention in PACG patients.

Background: Surgical ventricular restoration (SVR) has been performed to treat left ventricular (LV) aneurysm. However, there is limited analysis of changes in LV shape. This study aimed to evaluate the changes in LV shape induced by SVR and the effects of SVR on LV size and function for LV aneurysm. Methods: Between April 2006 and March 2015, 18 patients with dyskinetic (dyskinetic group) and 12 patients with akinetic (akinetic group) postinfarction LV anterior aneurysm receiving SVR with the Dor procedure at Chinese People’s Liberation Army General Hospital were enrolled in this study. A retrospective analysis was carried out using data from the echocardiography database. LV shape was analyzed by calculating the apical conicity index (ACI). LV end-diastolic volume index, end-systolic volume index, and ejection fraction (EF) were measured. One-way analysis of variance was used to compare means at different time points within each group. Results: Within one week after SVR, LV shape became more conical in the two groups (ACI decreased from 0.84 ± 0.13 to 0.69 ± 0.11 [t = 5.155, P = 0.000] in dyskinetic group and from 0.73 ± 0.07 to 0.60 ± 0.11 [t = 2.701, P = 0.026] in akinetic group; LV volumes were decreased significantly and became closer to normal values and EF was improved significantly in the two groups). On follow-up at least one year, LV shape remained unchanged in dyskinetic group (ACI increased from 0.69 ± 0.11 to 0.74 ± 0.12, t = −1.109, P = 0.294), but became more spherical in akinetic group (ACI significantly increased from 0.60 ± 0.11 to 0.75 ± 0.11, t = −1.880, P = 0.047); LV volumes remained unchanged in dyskinetic group, but increased significantly in akinetic group and EF remained unchanged in the two groups. Conclusions: SVR could reshape LV to a more conical shape and a more normal size and improve LV function significantly early after the procedure in patients with dyskinetic or akinetic postinfarction LV anterior aneurysm. However, LV tends to be more spherical and enlarged in the akinetic group on at least 1-year follow-up.

Background: Avascular necrosis of femoral head (AVNFH) typically presents in the young adults and progresses quickly without proper treatments. However, the optimum treatments for early stage of AVNFH are still controversial. This study was conducted to evaluate the therapeutic effects of multiple small-diameter drilling decompression combined with hip arthroscopy for early AVNFH compared to drilling alone. Methods: This is a nonrandomized retrospective case series study. Between April 2006 and November 2010, 60 patients (98 hips) with early stage AVNFH participated in this study. The patients underwent multiple small-diameter drilling decompression combined with hip arthroscopy in 26 cases/43 hips (Group A) or drilling decompression alone in 34 cases/55 hips (Group B). Patients were followed up at 6, 12, and 24 weeks, and every 6 months thereafter. Radiographs were taken at every follow-up, Harris scores were recorded at the last follow-up, the paired t-test was used to compare the postoperative Harris scores. Surgery effective rate of the two groups was compared using the Chi-square test. Results: All patients were followed up for an average of 57.6 months (range: 17–108 months). Pain relief and improvement of hip function were assessed in all patients at 6 months after the surgery. At the last follow-up, Group A had better outcome with mean Harris’ scores improved from 68.23 ± 11.37 to 82.07 ± 2.92 (t = −7.21, P = 0.001) than Group B with mean Harris’ scores improved from 69.46 ± 9.71 to 75.79 ± 4.13 (t = –9.47, P = 0.037) (significantly different: t = –2.54, P = 0.017). The total surgery effective rate was also significantly different between Groups A and B (86.0% vs. 74.5%; χ2 = 3.69, P = 0.02). Conclusion: For early stage of AVNFH, multiple small-diameter drilling decompression combined with hip arthroscopy is more effective than drilling decompression alone.

Background: Mental disorders are strongly associated with disabilities. National survey on disability could provide a reliable basis for policymaking in care and rehabilitation of disabled persons. This study aimed to describe the disability prevalence rates attributed to mental disorders, their distribution by sociodemographic factors, and utilizations of service. Methods: This study is a secondary data analysis of the Second National Sample Survey on Disability in 2006. The disability and severity were assessed using the World Health Organization DisabilityAssessment Schedule 2.0. Mental disorders were diagnosed according to the International Statistical Classification of Diseases and Related Health Problems 10th Revision Classification of Mental and Behavioral Disorders. Using descriptive and analytic epidemiological methods, prevalence rates of disability attributed to mental disorders and service use were calculated. Results: Data of 2,526,145 respondents were analyzed. The disability prevalence rate attributed to mental disorders in China was 6.3‰, accounting for 9.9% of all disabled people. Regarding disability prevalence attributed to mental disorders, it showed that gender, residential area, marital status, education level, and economic area were related to the prevalence distributions. The proportions of mild disability were highest in the disabled people with onset age of 18–64 years, while the proportion of extremely severe disability was highest in the disabled people with onset age of 65 years and above. Only 58.6% of disabled people attributed to mental disorders used some of the services. Conclusions: There are statistical differences of disability prevalence attributed to mental disorders by people and region in China. Service use in disabled people with mental disorders is insufficient.

Background: Drug resistance to targeted therapies occurs in lung cancer, and resistance mechanisms related to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are continuously being discovered. We aimed to establish a novel method for highly parallel multiplexed detection of genetic mutations related to EGFR TKI-resistant lung cancer using Agena iPLEX chemistry and matrix-assisted laser desorption ionization time-of-flight analysis on the MassARRAY mass spectrometry platform. Methods: A review of the literature revealed 60 mutation hotspots in seven target genes (EGFR, KRAS, PIK3CA, BRAF, ERBB2, NRAS, and BIM) that are closely related to EGFR TKI resistance to lung cancer. A total of 183 primers comprised 61 paired forward and reverse amplification primers, and 61 matched extension primers were designed using Assay Design Software. The detection method was established by analyzing nine cell lines, and by comparison with LungCarta™ kit in ten lung cancer specimens. EGFR, KRAS, and BIM genes in all cell lines and clinical samples were subjected to Sanger sequencing for confirming reproducibility. Results: Our data showed that designed panel was a high-throughput and robust tool, allowing genotyping for sixty hotspots in the same run. Moreover, it made efficient use of patient diagnostic samples for a more accurate EGFR TKIs resistance analysis. The proposed method could accurately detect mutations in lung cancer cell lines and clinical specimens, consistent with those obtained by the LungCarta™ kit and Sanger sequencing. We also established a method for detection of large-fragment deletions based on single-base extension technology of MassARRAY platform. Conclusions: We established an effective method for high-throughput detection of genetic mutations related to EGFR TKI resistance based on the MassARRAY platform, which could provide more accurate information for overcoming cancers with de novo or acquired resistance to EGFR-targeted therapies.

Background: The E-26 transformation-specific related gene (ERG) is frequently expressed in cytogenetically normal acute myeloid leukemia (CN-AML). Herein, we performed a meta-analysis to investigate the relationship between the prognostic significance of ERG expression and CN-AML. Methods: A systematic review of PubMed database and other search engines were used to identify the studies between January 2005 and November 2016. A total of 667 CN-AML patients were collected from seven published studies. Of the 667 patients underwent intensive chemotherapy, 429 had low expression of ERG and 238 had high expression of ERG. Summary odds ratio (OR) and the 95% confidence interval (CI) for the ERG expression and CN-AML were calculated using fixed- or random-effects models. Heterogeneity was assessed using Chi-squared-based Q-statistic test and I2 statistics. All statistical analyses were performed using R.3.3.1 software packages (R Foundation for Statistical Computing, Vienna, Austria) and RevMan5.3 (Cochrane Collaboration, Copenhagen, Denmark). Results: Overall, patients with high ERG expression had a worse relapse (OR = 2.5127, 95% CI: 1.5177–4.1601, P = 0.0003) and lower complete remission (OR = 0.3495, 95% CI: 0.2418–0.5051, P < 0.0001). With regard to the known molecular markers, both internal tandem duplications of the fms-related tyrosine kinase 3 gene (OR = 3.8634, 95% CI: 1.8285–8.1626, P = 0.004) and brain and acute leukemia, cytoplasmic (OR = 3.1538, 95% CI: 2.0537–4.8432, P < 0.0001) were associated with the ERG expression. In addition, the results showed a statistical significance between French-American-British (FAB) classification subtype (minimally differentiated AML and AML without maturation, OR = 4.7902, 95% CI: 2.7772–8.2624, P < 0.0001; acute monocytic leukemia, OR = 0.2324, 95% CI: 0.0899–0.6006, P = 0.0026) and ERG expression. Conclusion: High ERG expression might be used as a strong adverse prognostic factor in CN-AML.

Objective: The aim is to update our clinical recommendations for evidence-based language rehabilitation of people with aphasia, based on a systematic review of the literature from 1999 to 2015. Data Sources: Articles referred to in this systematic review of the Medline and PubMed published in English language literatures were from 1998 to 2015. The terms used in the literature searches were aphasia and evidenced-based. Study Selection: The task force initially identified citations for 51 published articles. Of the 51 articles, 44 studies were selected after further detailed review. Six articles, which were not written in English, and one study related to laryngectomy rehabilitation interventions, were excluded from the study. This study referred to all the important and English literature in full. Results: Aphasia is the linguistic disability, which usually results from injuries to the dominant hemisphere of the brain. The rehabilitation of aphasia is until in the process of being debated and researched. Evidence-based medicine (EBM), EBM based on the clinical evidence, promotes the practice of combining the clinicians’ first-hand experience and the existing objective and scientific evidence encouraging making decisions based on both empirical evidence and the scientific evidence. Currently, EBM is being gradually implemented in the clinical practice as the aim of the development of modern medicine. Conclusions: At present, the research for the aphasia rehabilitation mainly focuses on the cognitive language rehabilitation and the intensive treatment and the precise treatment, etc. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for linguistic disability after traumatic brain injury and stroke, which can be used to develop linguistic rehabilitation guidelines for patients with aphasia.
