Abstract
Follicle-stimulating hormone (FSH) is involved in mammalian reproduction via binding to FSH receptor (FSHR). However, several studies have found that FSH and FSHR play important roles in extragonadal tissue. Here, we identified the expression of FSHR in human and mouse pancreatic islet β-cells. Blocking FSH signaling by Fshr knock-out led to impaired glucose tolerance owing to decreased insulin secretion, while high FSH levels caused insufficient insulin secretion as well. In vitro, we found that FSH orchestrated glucose-stimulated insulin secretion (GSIS) in a bell curve manner. Mechanistically, FSH primarily activates Gαs via FSHR, promoting the cAMP/protein kinase A (PKA) and calcium pathways to stimulate GSIS, whereas high FSH levels could activate Gαi to inhibit the cAMP/PKA pathway and the amplified effect on GSIS. Our results reveal the role of FSH in regulating pancreatic islet insulin secretion and provide avenues for future clinical investigation and therapeutic strategies for postmenopausal diabetes.

Abstract
Objective: To investigate the risk factors of diabetic nephropathy (DN) in primary type 2 diabetes mellitus (T2DM) patients and to quantitatively analyze the risk of DN by nomogram modeling. Methods: A total of 1 588 primary T2DM patients from 17 townships and streets in Zhejiang Province were enrolled from June 2018 to August 2018 in this cross-sectional study, with an average age of (56.8±10.1) years (50.06% male) and a mean disease duration of 9 years. The clinical data, biochemical test results, and fundus photographs of all T2DM patients were collected, and logistic regression analysis was used to screen the risk factors of DN. Then, a nomogram model was used to quantitatively analyze the risk of DN. Results: DN occurred in 27.71% (440/1 588 cases) primary type 2 diabetes patients. Hemoglobin A1c (HbA1c) (OR=1.159, 95%CI 1.039-1.292), systolic blood pressure (OR=1.041, 95%CI 1.031-1.051), serum creatinine (Scr) (OR=1.011, 95%CI 1.004-1.017), serum globulin (GLOB) (OR=1.072, 95%CI 1.039-1.105), diabetic retinopathy (DR) (OR=1.463, 95%CI 1.073-1.996), education level of more than junior high school (OR=2.018, 95%CI 1.466-2.777), and moderate-intensity exercise (OR=0.751, 95%CI 0.586-0.961) were influencing factors of DN. Nomogram model analysis showed that the total score of each factor of DN ranged from 64-138 points, and the corresponding risk rate ranged from 0.1-0.9. The nomogram model also predicted a C-index value of 0.753 (95%CI 0.726-0.781) and an area under the receiver operating characteristic curve of DN of 0.753. Internal verification of the C-index reached 0.738. The model displayed medium predictive power and could be applied in clinical practice. Conclusions: HbA1c, systolic blood pressure, Scr, GLOB, DR, and more than a junior high school education are independent risk factors of DN. Nomogram modeling can more intuitively evaluate the risk of DN in primary T2DM patients.

Abstract
BACKGROUND Fertility awareness and menses prediction are important for improving fecundability and health management. Previous studies have used physiological parameters, such as basal body temperature (BBT) and heart rate (HR), to predict the fertile window and menses. However, their accuracy is far from satisfactory. Additionally, few researchers have examined irregular menstruators. Thus, we aimed to develop fertile window and menstruation prediction algorithms for both regular and irregular menstruators. METHODS This was a prospective observational cohort study conducted at the International Peace Maternity and Child Health Hospital in Shanghai, China. Participants were recruited from August 2020 to November 2020 and followed up for at least four menstrual cycles. Participants used an ear thermometer to assess BBT and wore the Huawei Band 5 to record HR. Ovarian ultrasound and serum hormone levels were used to determine the ovulation day. Menstruation was self-reported by women. We used linear mixed models to assess changes in physiological parameters and developed probability function estimation models to predict the fertile window and menses with machine learning. RESULTS We included data from 305 and 77 qualified cycles with confirmed ovulations from 89 regular menstruators and 25 irregular menstruators, respectively. For regular menstruators, BBT and HR were significantly higher during fertile phase than follicular phase and peaked in the luteal phase (all P < 0.001). The physiological parameters of irregular menstruators followed a similar trend. Based on BBT and HR, we developed algorithms that predicted the fertile window with an accuracy of 87.46%, sensitivity of 69.30%, specificity of 92.00%, and AUC of 0.8993 and menses with an accuracy of 89.60%, sensitivity of 70.70%, and specificity of 94.30%, and AUC of 0.7849 among regular menstruators. For irregular menstruators, the accuracy, sensitivity, specificity and AUC were 72.51%, 21.00%, 82.90%, and 0.5808 respectively, for fertile window prediction and 75.90%, 36.30%, 84.40%, and 0.6759 for menses prediction. CONCLUSIONS By combining BBT and HR recorded by the Huawei Band 5, our algorithms achieved relatively ideal performance for predicting the fertile window and menses among regular menstruators. For irregular menstruators, the algorithms showed potential feasibility but still need further investigation. TRIAL REGISTRATION ChiCTR2000036556. Registered 24 August 2020.

Abstract
BACKGROUND Poor sleep quality and maternal mood disturbances are common during pregnancy and may play pivotal roles in the development of postpartum depression. We aim to examine the trajectories of sleep quality and mental health in women from early pregnancy to delivery and explore the mediating effects of sleep quality and mental status on the link between antepartum depressive symptoms and postpartum depressive symptoms. METHODS In an ongoing prospective birth cohort, 1301 women completed questionnaires in the first, second and third trimesters and at 6 weeks postpartum. In each trimester, sleep quality was measured utilizing the Pittsburgh Sleep Quality Index (PSQI), and mental health was assessed with the Center for Epidemiologic Studies Depression Scale (CES-D), the Self-Rating Anxiety Scale (SAS) and the Perceived Stress Scale (PSS). Postpartum depressive symptoms were evaluated by the Edinburgh Postnatal Depression Scale (EPDS). The bootstrap method was used to test the mediation effect. RESULTS The PSQI, CES-D, and SAS scores presented U-shaped curves across the antenatal period while the PSS score followed a descending trend. Antenatal sleep quality, depressive symptoms, anxiety symptoms and perceived stress all predicted depressive symptoms at 6 weeks postpartum. The influence of antepartum depressive symptoms on postpartum depressive symptoms was mediated by antepartum sleep quality and anxiety symptoms, which accounted for 32.14%, 39.25% and 31.25% in the first, second and third trimesters (P = 0.002, P = 0.001, P = 0.001, respectively). CONCLUSIONS Poor sleep quality and anxiety symptoms in pregnancy mediated the relationship between antepartum depressive symptoms and postpartum depressive symptoms. Interventions aimed at detecting and managing sleep quality and elevated anxiety among depressed women in pregnancy warrant further investigation as preventative strategies for postpartum depression.

Abstract
INTRODUCTION Conventional intracytoplasmic sperm injection (ICSI) is a widely used treatment for couples with severe male infertility. However, there are controversies regarding the selection and the damage to gametes during the ICSI procedure. Although preimplantation genetic testing for aneuploidies (PGT-A) can give genetic information about embryos for transfer and improve fertility rate, and it is widely used in women with recurrent spontaneous abortion or advanced age, PGT-A is not only more expensive but also has unclear effectiveness with respect to the improvement of fertility rate among couples with severe male infertility. High-quality, well-powered randomised clinical trials (RCTs) comparing ICSI+PGT-A and ICSI are lacking. METHODS AND ANALYSIS This is a protocol for a multicenter, open-label RCT in four reproductive medical centers qualified for PGT technique in China. We will study couples with severe male infertility scheduled for their fertility treatment. After the blastocyst culture, eligible participants are randomised to the ICSI+PGT-A group or the conventional ICSI group in a 1:1 ratio. Other assisted reproductive procedures are similar and parallel between the two groups. The primary outcome will be live birth rate and cumulative live-birth rate . Secondary outcomes will be embryo implantation rate, biochemical pregnancy rate, clinical pregnancy rate, spontaneous abortion rate, ongoing pregnancy rate, preterm birth rate, fetal chromosomal abnormality rate, birth defect rate and treatment complications. To demonstrate or refute a difference between the two groups, we plan to include 188 participants in each group; taking consideration of 20% of dropout, the total target sample size is 450. ETHICS AND DISSEMINATION Ethical approval was obtained from International Peace Maternity and Child Health Hospital of Shanghai Jiao Tong University Medical Science Research Ethics Committee (GKLW2016-16). Informed consent will be obtained from each participant. The findings will be disseminated to the public through conference presentations and publication in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT02941965.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a complex of interrelated risk factors, including central adiposity, increased blood pressure, hyperglycemia, elevated triglyceride levels and low high-density lipoprotein. Few studies have reported the genetic variants in the Sirt1 and Nrf2 genes (Sirt1 rs7895833 A > G, Sirt1 rs2273773 C > T and Nrf2 rs6721961 C > A) that increase the risk of type 2 diabetes mellitus and are correlated with some glycemic and metabolic traits in the Chinese Han population. METHODS Our study recruited 141 individuals with MetS and 549 individuals without MetS to investigate the associations between three single nucleotide polymorphisms (SNPs) of Sirt1 and Nrf2 and the risk of MetS in a Chinese Han population using the PCR-CTPP method. RESULTS This research showed that the risk of MetS was 2.41 times higher for the AA genotype (P = 0.038) and 1.94 times higher for the AG genotype (P = 0.016) compared with carriers of the GG genotype. The serum levels of low-density lipoprotein cholesterol and HOMA-IR were significantly higher (P < 0.05) in carriers of the AA genotype of Sirt1 rs7895833 than in carriers of the AG and GG genotypes in the general population. The serum level of total cholesterol in the AA genotype was lower (P = 0.033) than that in the other two genotypes. However, the genotype frequencies of Sirt1 rs2273773 and Nrf2 rs6721961 in the MetS group were not significantly different from those in the control subjects, and those two genetic variants were not correlated with metabolic traits. CONCLUSIONS These results underscore the contributions of SNPs of Sirt1 rs7895833 to MetS susceptibility as well as glycemic and metabolic traits in a Chinese population.

Abstract
Purpose: To estimate whether the city-specific lockdown in Shanghai induced by the COVID-19 pandemic affected preterm birth rates among uninfected pregnant women in different trimesters. Methods: The population-based retrospective cohort study was conducted in the International Peace Maternity and Child Health Hospital (IPMCH) in Shanghai, China. Pregnant women without COVID-19 received perinatal healthcare during lockdown (from January 24, 2020 to March 24, 2020) and non-lockdown (from January 24, 2019 to March 24, 2019) period and giving birth to a live infant at IPMCH were enrolled. 1:1 propensity score matching and Inverse probability of treatment weighting were used to evaluate preterm birth (<37 weeks), very preterm birth (<34 weeks), preterm birth with premature rupture of membranes (PROM-PTB), spontaneous preterm birth with intact membranes (S-PTB), and medically induced preterm birth (MI-PTB) between two groups. Results: 8,270 pregnant women were in the lockdown group, and 9,815 were in the non-lockdown group. Pregnant women in second trimester during lockdown had a higher risk of PTB than those during the non-lockdown period [OR: 1.43 (CI 1.01–2.02), ARD: 1.7% (CI 0.04–3.4%), p = 0.045]. Furthermore, pregnant women in third trimester during lockdown had a higher risk of PROM-PTB than those during the non-lockdown period [OR: 1.64 (CI 1.09–2.47), ARD: 0.9% (CI 0.2–1.6%), p = 0.02]; no group differences were found related to rates of VPTB, S-PTB or MI-PTB. Conclusion: In this cohort study in China, we found that there was an increased risk in preterm birth for non-infected women in COVID-19 lockdown who were in their second trimester.

Abstract
A high maternal triglyceride (mTG) level during early pregnancy is linked to adverse pregnancy outcomes, but the use of specific interventions has been met with limited success. A retrospective cohort study was designed to investigate the impact of gestational weight gain (GWG) on the relationship between high levels of mTG and adverse pregnancy outcomes in normal early pregnancy body mass index (BMI) women. The patients included 39,665 women with normal BMI who had a singleton pregnancy and underwent serum lipids screening during early pregnancy. The main outcomes were adverse pregnancy outcomes, including gestational hypertension, preeclampsia, gestational diabetes, cesarean delivery, preterm birth, and large or small size for gestational age (LGA or SGA) at birth. As a result, the high mTG (≥2.05mM) group had increased risks for gestational hypertension ((Adjusted odds ratio (AOR), 1.80; 95% CI, 1.46 to 2.24)), preeclampsia (1.70; 1.38 to 2.11), gestational diabetes (2.50; 2.26 to 2.76), cesarean delivery (1.22; 1.13 to 1.32), preterm birth (1.42, 1.21 to 1.66), and LGA (1.49, 1.33 to 1.68) compared to the low mTG group, after adjustment for potential confounding factors. Additionally, the risks of any adverse outcome were higher in each GWG subgroup among women with high mTG than those in the low mTG group. High mTG augmented risks of gestational hypertension, preeclampsia, preterm birth, and LGA among women with 50th or greater percentile of GWG. Interestingly, among women who gained less than the 50th percentile of GWG subgroups, there was no relationship between high mTG level and risks for those pregnancy outcomes when compared to low mTG women. Therefore, weight control and staying below 50th centile of the suggested GWG according to gestational age can diminish the increased risks of adverse pregnancy outcomes caused by high mTG during early pregnancy.

Abstract
Insulin resistance (IR) is one of the most common features of polycystic ovary syndrome (PCOS), which is related to obesity. Whether increased anti-Müllerian hormone (AMH) levels in PCOS are involved in the pathogenesis of insulin resistance remains unclear. We investigated serum levels of leptin and AMH along with basic clinical and metabolic parameters in 114 PCOS patients and 181 non-PCOS women. PCOS patients presented higher fasting blood glucose, insulin concentrations and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) in addition to body mass index (BMI), lipids profiles and hormone levels. HOMA-IR showed a positive correlation with BMI, AMH, leptin, and low-density lipoprotein-cholesterol (LDL-c) levels. Interestingly, AMH is strongly positively correlated with HOMA-IR and insulin concentrations for 1st and 2nd hours of glucose treatment after fasting. Among PCOS women with BMI≥25 kg/m2, high AMH level group showed an increased HOMA-IR when compared to normal AMH level. However, among PCOS women with normal BMI, women with high AMH presented an elevated fasting insulin levels but not HOMA-IR when compared to normal AMH group. In vitro treatment of isolated islet cells with high concentration of leptin (200 ng/ml) or high leptin plus high concentration of AMH (1 ng/ml) significantly enhanced insulin secretion. Importantly, co-treatment of AMH plus leptin upregulates the expression of pro-apoptotic proteins, such as Bax, caspase-3, and caspase-8 after incubating with a high level of glucose. These results suggest that AMH may involve in the pathological process of pancreatic β-cells in obese PCOS women.

Abstract
The pandemic of Coronavirus Disease 2019(COVID-19) could be sources of anxiety among pregnant women and health care workers, which might affect the decision making on the mode of delivery. The aim of this study was to explore whether the cesarean section rates had significantly increased after the outbreak of COVID-19. We analyzed the labor data with cesarean rates in a tertiary maternity center during COVID-19 epidemic months from January to March in 2020, compared with pre-epidemic parallel months in 2019 by using Z-score test for proportions. Even though none of the staff or patient suffered with COVID-19 in the hospital, we found the cesarean section rates slightly increased in a non-infected population after the outbreak of COVID-19. Obstetricians should beware of the possible effects of COVID-19 on the mode of delivery.

Abstract
Traditionally, the anteroventral periventricular (AVPV) nucleus has been the brain area associated with luteinizing hormone (LH) surge secretion in rodents. However, the role of the other population of hypothalamic kisspeptin neurons, in the arcuate nucleus (ARC), has been less well characterized with respect to surge generation. Previous experiments have demonstrated ARC kisspeptin knockdown reduced the amplitude of LH surges, indicating that they have a role in surge amplification. The present study used an optogenetic approach to selectively stimulate ARC kisspeptin neurons and examine the effect on LH surges in mice with different hormonal administrations. LH level was monitored from 13:00 to 21:00 h, at 30-minute intervals. Intact Kiss-Cre female mice showed increased LH secretion during the stimulation period in addition to displaying a spontaneous LH surge around the time of lights off. In ovariectomized Kiss-Cre mice, optogenetic stimulation was followed by a surge-like secretion of LH immediately after the stimulation period. Ovariectomized Kiss-Cre mice with a low dose of 17β-estradiol (OVX+E) replacement displayed a surge-like increase in LH release during period of optic stimulation. No LH response to the optic stimulation was observed in OVX+E mice on the day of estradiol benzoate (EB) treatment (day 1). However, after administration of progesterone (day 2), all OVX+E+EB+P mice exhibited an LH surge during optic stimulation. A spontaneous LH surge also occurred in these mice at the expected time. Taken together, these results help to affirm the fact that ARC kisspeptin may have a novel amplificatory role in LH surge production, which is dependent on the gonadal steroid milieu.

Abstract
As an emerging environmental pollutant, microplastics have attracted more and more attention for its influence on the ecological environment and human health. Due to its wide range of usage and production, difficult degradation and other characteristics, as well as the continuous and substantial increase in the use of plastic products, the number of plastic fragments in the environment continues to increase, which leads to the accumulation of microplastics in the environment and organisms, spread through the food chain, and ultimately poses a threat to human health. At the same time, in the plastic production, synthetic textile, and other industries, the incidence of workers related occupational diseases greatly increased. In this paper, the concept, classification, source, impact on biological and human health of microplastics are summarized, and propose solutions on the current situation of microplastics pollution in China, we hope this review could provide effective reference for further carry out risk assessment of microplastics pollution on human health and formulate legislation to control microplastics pollution.

Abstract
Fertilization failure often occurs during in vitro fertilization (IVF) cycles despite apparently normal sperm and oocytes. Accumulating evidence suggests that mitochondria play crucial roles in the regulation of sperm function and male fertility. 3-Nitrophthalic acid (3-NPA) can induce oxidative stress in mitochondria, and melatonin, as an antioxidant, can improve mitochondrial function by reducing mitochondrial oxidative stress. The role of sperm mitochondrial dysfunction in fertilization failure during IVF is unclear. The present study revealed that spermatozoa with low, or poor, fertilization rates had swollen mitochondria, increased mitochondria-derived ROS, and attenuated mitochondrial respiratory capacity. 3-NPA treatment enhanced mitochondrial dysfunction in sperm. Spermatozoa with poor fertilization rates, and spermatozoa treated with 3-NPA, had reduced penetration ability. The concentration of melatonin was decreased in semen samples with low and poor fertilization rates. Melatonin, not only decreased excessive mitochondria-derived ROS, but also 'rescued' the reduced penetration capacity of spermatozoa treated with 3-NPA. Taken together, the study suggested that mitochondria-derived ROS and mitochondrial respiratory capacity are independent bio-markers for sperm dysfunction, and melatonin may be useful in improving sperm quality and overall male fertility.

Abstract
The recommendations for the diagnosis of stage 1 hypertension were recently revised by the American Heart Association primarily based on its impact on cardiovascular disease risks. Whether the newly diagnosed stage 1 hypertension impacts pregnancy complications remain poorly defined. We designed a retrospective cohort study to investigate the associations of stage 1 hypertension detected in early gestation (<20 weeks) with risks of adverse pregnancy outcomes stratified by prepregnancy body mass index. A total of 47 874 women with singleton live births and blood pressure (BP) <140/90 mm Hg were included, with 5781 identified as stage 1a (systolic BP, 130-134 mm Hg; diastolic BP, 80-84 mm Hg; or both) and 3267 as stage 1b hypertension (systolic BP, 135-139 mm Hg; diastolic BP, 85-90 mm Hg; or both). Slightly higher, yet significant, rates and risks of gestational diabetes mellitus, preterm delivery, and low birth weight (<2500 g) were observed in both groups compared with normotensive controls. Importantly, women with stage 1a and stage 1b hypertension had significantly increased incidences of hypertensive disorders in pregnancy compared with normotensive women (adjusted odds ratio, 2.34 [95% CI, 2.16-2.53]; 3.05 [2.78-3.34], respectively). After stratifying by body mass index, stage 1a and 1b hypertension were associated with increased hypertensive disorders in pregnancy risks in both normal weight (body mass index, 18.5-24.9; adjusted odds ratio, 2.44 [2.23-2.67]; 3.26 [2.93-3.63]) and the overweight/obese (body mass index, ≥25; adjusted odds ratio, 1.90 [1.56-2.31]; 2.36 [1.92-2.90]). Current findings suggested significantly increased adverse pregnancy outcomes associated with stage 1 hypertension based on the revised American Heart Association guidelines, especially in women with prepregnancy normal weight.

Abstract
The prostanoid EP4 receptor is one of the key receptors associated with inflammatory mediator PGE2-elicited immunosuppression in the tumor microenvironment. Blockade of EP4 signaling to enhance immunity-mediated tumor elimination has recently emerged as a promising strategy for cancer immunotherapy. In our efforts to discover novel subtype-selective EP4 antagonists, we designed and synthesized a class of 1H-1,2,3-triazole-based ligands that display low nanomolar antagonism activity toward the human EP4 receptor and excellent subtype selectivity. The most promising compound 59 exhibits single-digit nanomolar potency in the EP4 calcium flux and cAMP-response element reporter assays and effectively suppresses the expression of multiple immunosuppression-related genes in macrophage cells. On the basis of its favorable ADMET properties, compound 59 was chosen for further in vivo biological evaluation. Oral administration of compound 59 significantly inhibited tumor growth in the mouse CT26 colon carcinoma model accompanied by enhanced infiltration of cytotoxic T lymphocytes in the tumor tissue.

Abstract
CONTEXT Maternal obesity increases the risk of preterm delivery. Obesity is known to be associated with altered lipid metabolism. OBJECTIVE To investigate the associations between high maternal triglyceride (mTG) levels during early pregnancy and risks of preterm delivery stratified by early pregnancy body mass index (BMI). DESIGN Retrospective cohort study. SETTING University-based maternity center. PATIENTS 49,612 women with singleton pregnancy who underwent fasting serum lipid screening during early pregnancy. MAIN OUTCOME MEASURES Risk of preterm delivery (total, <37 weeks; early, 28 to 33 weeks; and late, 34 to 36 weeks). RESULTS Among women enrolled, 2494 had a preterm delivery, including 438 early preterm and 2056 late preterm delivery. High mTG (>90th percentile, 2.04 mM) was associated with shortened gestation. Risks of total, early, and late preterm deliveries increased with mTG levels, and the high mTG-related risk was highest for early preterm delivery [adjusted odds ratio (AOR) 1.72; 95% CI, 1.30 to 2.29]. After stratification by BMI, high mTG was associated with risk of preterm delivery in both overweight or obese (OWO) women (AOR 1.32; 95% CI, 1.02 to 1.70) and women with normal BMI (AOR 1.36; 95% CI, 1.16 to 1.59). In additional sensitivity analyses, we found that high mTG was related to higher risks of preterm delivery among OWO women and women with normal BMI (AOR, 1.54; 95% CI, 1.07 to 2.22 and 1.62, 1.34 to 1.96, respectively), especially early preterm delivery (AOR 2.47; 95% CI, 1.19 to 5.10, and AOR 2.50; 95% CI, 1.65 to 3.78, respectively). CONCLUSIONS High mTG level during early pregnancy increased the risks of preterm delivery not only in OWO women but also in women with normal BMI.

Abstract
Objective: To analyze the pathogens of lower respiratory tract infection(LRTI) including bacterial, viral and mixed infection, and to establish a discriminant model based on clinical features in order to predict the pathogens. Methods: A total of 243 hospitalized patients with lower respiratory tract infections were enrolled in Fujian Provincial Hospital from April 2012 to September 2015. The clinical data and airway (sputum and/or bronchoalveolar lavage) samples were collected. Microbes were identified by traditional culture (for bacteria), loop-mediated isothermal amplification(LAMP) and gene sequencing (for bacteria and atypical pathogen), or Real-time quantitative polymerase chain reaction (Real-time PCR)for viruses. Finally, a discriminant model was established by using the discriminant analysis methods to help to predict bacterial, viral and mixed infections. Results: Pathogens were detected in 53.9% (131/243) of the 243 cases.Bacteria accounted for 23.5%(57/243, of which 17 cases with the virus, 1 case with Mycoplasma pneumoniae and virus), mainly Pseudomonas Aeruginosa and Klebsiella Pneumonia. Atypical pathogens for 4.9% (12/243, of which 3 cases with the virus, 1 case of bacteria and viruses), all were mycoplasma pneumonia. Viruses for 34.6% (84/243, of which 17 cases of bacteria, 3 cases with Mycoplasma pneumoniae, 1 case with Mycoplasma pneumoniae and bacteria) of the cases, mainly Influenza A virus and Human Cytomegalovirus, and other virus like adenovirus, human parainfluenza virus, respiratory syncytial virus, human metapneumovirus, human boca virus were also detected fewly. Seven parameters including mental status, using antibiotics prior to admission, complications, abnormal breath sounds, neutrophil alkaline phosphatase (NAP) score, pneumonia severity index (PSI) score and CRUB-65 score were enrolled after univariate analysis, and discriminant analysis was used to establish the discriminant model by applying the identified pathogens as the dependent variable. The total positive predictive value was 64.7%(77/119), with 66.7% for bacterial infection, 78.0% for viral infection and 33.3% for the mixed infection. Conclusions: The mostly detected pathogens were Pseudomonas aeruginosa, atypitcal pathogens, Klebsiella pneumoniae, influenza A virus and human cytomegalovirus in hospitalized patients with LRTI in this hospital. The discriminant diagnostic model established by clinical features may contribute to predict the pathogens of LRTI.

Abstract
BACKGROUND Infants being born Large-for-gestational-age (LGA) are prone to developing cardiometabolic disease. However, the underlying mechanisms remain unclear. RESULTS Clinical investigation showed that children born LGA had significantly higher serum level of total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-c), and insulin, ratio of TC/high-density lipoprotein-cholesterol (HDL-c) compared to children born appropriate for gestational age (AGA). Birth weight (BW) was positively correlated to TC, LDL-c, and the ratio of TC/HDL in serum. Genome-wide DNA methylation analyzed in umbilical cord blood of controls and macrosomia cases. We identified 3459 methylation variable positions (MVPs) achieving genome-wide significance (adjusted P-value < 0.05) with methylation differences of ≥ 5%. A total of 327 MVPs were filtered by methylation differences of ≥ 7% located within an island, which mapped to 213 genes. Function analysis using Ingenuity Pathway Analysis showed 16 genes enriched in "cardiovascular disease". Four genes included contributed to hyperlipidemia. MATERIALS AND METHODS Fifty-eight children aged 3-6 years born LGA and 123 subjects born AGA were enrolled. Anthropometric parameters and blood pressure (BP) were measured, and metabolic assessment was performed in all subjects. Genome-wide DNA methylation in umbilical blood was assayed by the 450K BeadChip in six AGA and six macrosomia newborns. CONCLUSIONS Our data indicate that excess birth weight may increase the risk of lipid dysfunction in children aged 3-6 years. It might through reprogramming a group of genes correlated to cardiovascular disease. The genes identified in this study might be potential biomarker for cardiometabolic disease.

Abstract
Objective As high glucose (HG) concentration in peritoneal dialysis (PD) solution is thought to contribute to peritoneal fibrosis, and angiotensin II receptor blockers (ARBs) may have a key role in preventing fibrosis as they may inhibit the TGF- ß1–Smad pathway, the aims of this in vitro study were to investigate 1) if HG affects the expression of Smad in human peritoneal mesothelial cells (HPMCs) and 2) if ARB (losartan) can inhibit this effect. Methods HPMCs, obtained from non-renal patients undergoing elective abdominal surgery, were stimulated by HG solutions with different concentrations (1.5%, 2.5%, 4.25%) of dextrose and mannitol, and by solutions containing combination with dextrose and losartan. The supernatant was assayed for TGF- ß1 by ELISA and cells were collected for the analysis of Smad family by RT-PCR and Western Blot. Results 1) HG up-regulated the expression of Smad2 on both gene and protein levels, especially in 2.5% and 4.25% dextrose groups (P&0.05), and also stimulated the expression of Smad4 in 4.25% dextrose group. However, the expression of Smad3 was not affected. 2) High osmolality as such (using mannitol) did not affect the TGF-ß1-Smad signaling pathway. 3) Losartan inhibited the expression of Smad2 on the gene level but not on the protein level. 4) HG up-regulated the level of TGF- ß1 with increasing dextrose concentration, while losartan partially inhibited this effect of HG on releasing of TGF-ß1. Conclusion A high glucose solution up-regulated the expression of Smad2 and Smad4, suggesting that the TGF- ß1-Smad pathway could be involved in the fibrosis of the peritoneum during PD. As losartan inhibited the expression of Smad2 on the gene level and reduced the concentration of TGF- ß1 in our study, the results of this in vitro study suggest that the use of angiotensin II receptor blockers might represent a possible way to prevent and treat peritoneal fibrosis in PD patients. However, further studies in vivo are needed to confirm this hypothesis.

Abstract
Previous studies have shown that increasing estradiol concentrations had a toxic effect on the embryo and were deleterious to embryo adhesion. In this study, we evaluated the physiological impact of estradiol concentrations on endometrial cells to reveal that serum estradiol levels probably targeted the endometrium in controlled ovarian hyperstimulation (COH) protocols. An attachment model of human choriocarcinoma (JAr) cell spheroids to receptive-phase endometrial epithelial cells and Ishikawa cells treated with different estradiol (10-9 M or 10-7 M) concentrations was developed. Differentially expressed protein profiling of the Ishikawa cells was performed by proteomic analysis. Estradiol at 10-7 M demonstrated a high attachment rate of JAr spheroids to the endometrial cell monolayers. Using iTRAQ coupled with LC-MS/MS, we identified 45 differentially expressed proteins containing 43 significantly upregulated and 2 downregulated proteins in Ishikawa cells treated with 10-7 M estradiol. Differential expression of C3, plasminogen and kininogen-1 by Western blot confirmed the proteomic results. C3, plasminogen and kininogen-1 localization in human receptive endometrial luminal epithelium highlighted the key proteins as possible targets for endometrial receptivity and interception. Ingenuity pathway analysis of differentially expressed proteins exhibited a variety of signaling pathways, including LXR/RXR activation pathway and acute-phase response signaling and upstream regulators (TNF, IL6, Hmgn3 and miR-140-3p) associated with endometrial receptivity. The observed estrogenic effect on differential proteome dynamics in Ishikawa cells indicates that the human endometrium is the probable target for serum estradiol levels in COH cycles. The findings are also important for future functional studies with the identified proteins that may influence embryo implantation.

Abstract
Obesity appears to be associated with female reproductive dysfunction and infertility. Women with obesity undergoing in vitro fertilization (IVF) had poor oocyte quality, decreased embryo development, and poor pregnancy outcome. However, the mechanism linking obesity to poor reproductive outcomes is still unclear. Obesity is frequently accompanied with elevated leptin levels. Here we aimed to evaluate the effect of high leptin level in follicular fluid (FF) on the proliferation and apoptosis in granule cells and correlate these findings with poor reproductive outcomes in infertile women with overweight or obesity who underwent IVF treatment. We investigated clinical and ongoing pregnancy rates in 189 infertile women who underwent IVF. Leptin levels were quantified in peripheral blood and FF as well. In vitro cell model was used to explore the potential effect of high leptin on the proliferation and apoptosis in granulosa cells. Results showed reduced clinical and ongoing pregnancy rates in overweight/obesity women who underwent IVF compared to control with normal BMI. On the other hand, leptin levels presented significant increase in peripheral blood and FF in overweight/obese women. Leptin level in FF was negatively correlated to good quality embryo rate. Importantly, in vitro study showed that leptin inhibited cells proliferation and promoted apoptosis by upregulation of caspase-3 and downregulation of Bcl-2 in granulosa cells in a dose dependent manner. These observations suggest that leptin may acts as a local mediator to attenuate embryo development and reduce fertility in obese patients.

Abstract
The aim of the study was to explore the effect and its clinical relevance of short-term intensive insulin treatment on plasma concentrations of lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) and secretory phospholipase A(2) (sPLA(2)) in newly diagnosed type 2 diabetes mellitus (T2DM). Ninety newly diagnosed T2DM patients were recruited and received continuous subcutaneous insulin infusion (CSII) for about 2 weeks. After CSII, sPLA(2) levels [173.78 (80.95, 278.09) μg/L] were significantly decreased compared with the levels before [219.33 (130.03, 337.30) μg/L], P<0.01, while no statistic significant changes could be viewed in Lp-PLA(2) levels. Correlation analysis showed that the changes of Lp-PLA(2) and sPLA(2) were both positively correlated with the changes of homeostasis model assessment of insulin resistance(HOMA-IR)after CSII (r=0.537, 0.493 respectively, all P<0.05). The Lp-PLA(2) and sPLA(2) level reduction after CSII might help to protect the patients from diabetic macroangiopathy. Trial registration Chinese Clinical Trial Registry, ChiCTR-TRC-10001618.

Abstract
Background Excessive androgen exposure during pregnancy has been suggested to induce diabetic phenotypes in offspring in animal models. The aim of this study was to investigate whether pregestational maternal hyperandrogenism in human influenced the glucose metabolism in offspring via epigenetic memory from mother's oocyte to child's somatic cells. Methods Of 1782 reproductive-aged women detected pregestational serum androgen, 1406 were pregnant between 2005 and 2010. Of 1198 women who delivered, 1116 eligible mothers (147 with hyperandrogenism and 969 normal) were recruited. 1216 children (156 children born to mothers with hyperandrogenism and 1060 born to normal mother) were followed up their glycometabolism in mean age of 5 years. Imprinting genes of oocyte from mothers and lymphocytes from children were examined. A pregestational hyperandrogenism rat model was also established. Findings Children born to women with hyperandrogenism showed increased serum fasting glucose and insulin levels, and were more prone to prediabetes (adjusted RR: 3.98 (95%CI 1.16–13.58)). Oocytes from women with hyperandrogenism showed increased insulin-like growth factor 2 (IGF2) expression. Lymphocytes from their children also showed increased IGF2 expression and decreased IGF2 methylation. Treatment of human oocytes with dihydrotestosterone upregulated IGF2 and downregulated DNMT3a levels. In rat, pregestational hyperandrogenism induced diabetic phenotypes and impaired insulin secretion in offspring. In consistent with the findings in human, hyperandrogenism also increased Igf2 expression and decreased DNMT3a in rat oocytes. Importantly, the same altered methylation signatures of Igf2 were identified in the offspring pancreatic islets. Interpretation Pregestational hyperandrogenism may predispose offspring to glucose metabolism disorder via epigenetic oocyte inheritance. Clinical trial registry no.: ChiCTR-OCC-14004537; www.chictr.org. Maternal hyperandrogenism may increase the risks of glucose metabolism disorder and prediabetes in their children. High androgen levels in women may directly increased IGF2 expression and decreased IGF2 methylation in oocytes Intergenerational inheritance of epigenetic alteration could be regarded important in determining development of diabetes.
Hyperandrogenemia can be observed in most patients with polycystic ovarian syndrome that is a common endocrine disorder in women of reproductive age, especially in subfertile women. We found that maternal hyperandrogenism may increase the risks of glucose metabolism disorder and prediabetes in their children. Also, Data from human and rat suggest that this glucose metabolism disorder may be mediated by DNA methylation modifications, and this kind of epigenetic modification may be transmitted from oocytes of mothers to somatic cells of offspring. Hence, intergenerational inheritance of epigenetic alteration should be regarded important in determining development of diabetes in the future.

Abstract
Diabetic pregnancy, with ever increasing prevalence, adversely affects embryogenesis and increases vasculometabolic disorder risks in adult offspring. However, it remains poorly understood whether maternal diabetes increases the offspring's susceptibility to heart injuries in adulthood. In this study, we observed that cardiac function and structure were comparable between adult offspring born to diabetic mice and their counterparts born to nondiabetic mice at baseline. However, in response to myocardial ischemia/reperfusion (MIR), diabetic mother offspring exhibited augmented infarct size, cardiac dysfunction, and myocardial apoptosis compared with control, in association with exaggerated activation of mitochondria- and endoplasmic reticulum (ER) stress-mediated apoptosis pathways and oxidative stress. Molecular analysis showed that the impaired myocardial ischemic tolerance in diabetic mother offspring was mainly attributable to blunted cardiac insulin receptor substrate (IRS)-1/Akt signaling. Furthermore, the effect of maternal melatonin administration on offspring's response to MIR was determined, and the results indicated that melatonin treatment in diabetic dams during pregnancy significantly improved the tolerance to MIR injury in their offspring, via restoring cardiac IRS-1/Akt signaling. Taken together, these data suggest that maternal diabetes predisposes offspring to augmented MIR injury in adulthood, and maternal melatonin supplementation during diabetic pregnancy may hold promise for improving myocardial ischemic tolerance in the offspring.

Abstract
Polycystic ovary syndrome (PCOS) is a complex reproductive and metabolic disorder affecting 10 % of reproductive-aged women, and is well associated with an increased prevalence of cardiovascular risk factors. However, there are few data concerning the direct association of PCOS with cardiac pathologies. The present study aims to investigate the changes in cardiac structure, function, and cardiomyocyte survival in a PCOS model, and explore the possible effect of calcitriol administration on these changes. PCOS was induced in C57BL/6J female mice by chronic dihydrotestosterone administration, as evidenced by irregular estrous cycles, obesity and dyslipidemia. PCOS mice progressively developed cardiac abnormalities including cardiac hypertrophy, interstitial fibrosis, myocardial apoptosis, and cardiac dysfunction. Conversely, concomitant administration of calcitriol significantly attenuated cardiac remodeling and cardiomyocyte apoptosis, and improved cardiac function. Molecular analysis revealed that the beneficial effect of calcitriol was associated with normalized autophagy function by increasing phosphorylation levels of AMP-activated protein kinase and inhibiting phosphorylation levels of mammalian target of rapamycin complex. Our findings provide the first evidence for the presence of cardiac remodeling in a PCOS model, and vitamin D supplementation may be a potential therapeutic strategy for the prevention and treatment of PCOS-related cardiac remodeling.

Abstract
LIM domain kinase 1 (LIMK1), an actin-binding kinase, can phosphorylate and inactivate its substrates, and can regulate long-term memory and synaptic plasticity. Both β-amyloid precursor protein (App) and presenilin (PS) are functional degeneration factors during early neuronal development, and are considered as potential factors that contribute to the development of Alzheimer's disease (AD). However, hardly any information is available about the distribution and expression of LIMK1. Thus, using the App and PS deficient mice, the role of LIMK1 was demonstrated in the absence of App and PS. Our results showed that LIMK1 was present in the nerve fiber layer and external plexiform layer of the olfactory bulb, as well as in the mitral cells and Purkinje cells of the cerebellum in App and PS deficient mice. Additionally, LIMK1 was concentrated in the granule cell layer of the olfactory bulb and cerebellum and LIMK1 positive cells were located in the CA1 region of the hippocampus. Our study indicates that there is a connection between LIMK1 and AD in the mouse model of AD. This might explain neurological problems such as cerebellar ataxia, impaired long-term memory, and impaired synaptic plasticity observed in AD.

Abstract
Hyperosmotic stress may induce apoptosis of different cells. However, oocytes show tolerance to osmotic stress during cryopreservation by vitrification, which is an assisted reproductive technique. The underlying mechanism is still not understood. Here, we demonstrated that hyperosmosis produced by high concentrations of cryoprotectants, including DMSO, ethylene glycol and sucrose, significantly upregulated the protein levels of aquaporin (AQP) 7, but not AQP3 and AQP9, in mouse oocytes. Knockdown of AQP7 expression by siRNA-injection significantly reduced the survival of oocytes after vitrification. In oocytes, AQP7 was shown to bind with F-actin, a protein involved in almost all biological events. Moreover, we found that hyperosmosis could upregulate the phosphorylation levels of CPE-binding protein (CPEB) and Aurora A. Inhibition of the PI3K and PKC pathways blocked the hyperosmosis-induced upregulation of AQP7 and the phosphorylation of CPEB and Aurora A in oocytes. In conclusion, hyperosmosis could upregulate the expression of AQP7 via Aurora A/CPEB phosphorylation mediated by the PI3K and PKC pathways, and upregulation of AQP7 plays an important role in improving of tolerance to hyperosmotic stress and survival of oocytes during cryopreservation by vitrification.

Abstract
BACKGROUND The increasing number of babies conceived by in vitro fertilization and embryo transfer (IVF-ET) shifts concern from pregnancy outcomes to long-time health of offspring. Maternal high estradiol (E2) is a major characteristic of IVF-ET and lasts throughout the first trimester of pregnancy. The fetal thyroid develops during this period and may thus be affected by exposure to the supra-physiological E2. The aim of this study is to investigate whether the high E2 maternal environment in the first trimester increases the risk of thyroid dysfunction in children born following IVF-ET. METHODS A cross-sectional survey design was used to carry out face-to-face interviews with consecutive children attending the hospital. A total of 949 singletons born after fresh embryo transfer (ET) (n=357), frozen ET (n=212), and natural conception (NC) (n=380), aged 3 to 10 years old, were included. All children were thoroughly examined. Meanwhile, another 183 newborns, including 55 fresh ET, 48 frozen ET, and 80 NC were studied. Levels of serum T3, FT3, T4, FT4, and TSH and levels of maternal E2 at different stages of the first trimester were examined. RESULTS The mean serum E2 levels of women undergoing fresh ET during the first trimester of pregnancy were significantly higher than those of the women undergoing frozen ET or following NC. The thyroid hormone profile, especially the levels of T4, FT4, and TSH, were significantly increased in 3- to 10-year-old children conceived by fresh ET compared to NC. The same tendency was confirmed in newborns. However, levels of T4 and TSH in the frozen ET group were nearer to that of the NC group. Furthermore, levels of T4 and FT4 in fresh ET were positively correlated with maternal serum levels of E2 during early pregnancy. CONCLUSIONS The maternal high E2 environment in the first trimester is correlated with increased risk of thyroid dysfunction. Frozen ET could reduce risks of thyroid damage in children conceived by IVF. Further studies are needed to confirm these findings and to better determine the underlying molecular mechanisms and clinical significance. TRIAL REGISTRATION ChicCTR-OCC-14004682 (22-05-2014).

Abstract
CONTEXT The cardiovascular dysfunction in children born with assisted reproductive technologies has been of great concern. However, the association of ovarian hyperstimulation syndrome (OHSS), a complication of assisted reproductive technologies, with worse cardiovascular functions and underlying mechanism remains unknown. OBJECTIVES The objective of the study was to assess the cardiovascular functions of children born to mothers with OHSS and investigate the underlying regulator(s). DESIGN AND SETTING This was a retrospective cohort recruited in a university hospital. PARTICIPANTS AND METHODS We assessed the cardiovascular functions by Doppler echography in 42 children born to OHSS women, 34 children of mothers with non-OHSS in vitro fertilization, and 48 spontaneously conceived (SC) children (mean age ∼ 4.5 y). Groups were matched for gestational age at delivery and birth weight. An isobaric tag for relative and absolute quantitation-labeled proteomics analysis was performed with another set of umbilical arteries from OHSS and SC pregnancies (n = 3 for both groups). RESULTS Children of OHSS mothers showed a significantly decreased mitral ratio of early to late mitral peak velocities, reduced systolic and diastolic diameters of common carotid arteries, and impaired flow-mediated dilation compared with non-OHSS in vitro fertilization and SC children. Intima-media thickness and arterial stiffness indices were similar in the three groups. In the proteomics study, 1640 proteins were identified from OHSS and SC umbilical arteries, and 40 differentially expressed proteins were selected for further analysis. Estradiol and progesterone were identified as activated upstream regulators. CONCLUSIONS Children born to ovarian-hyperstimulated women displayed cardiovascular dysfunctions. The underlying mechanisms may involve the effects of supraphysiological estradiol and progesterone levels.

Abstract
OBJECTIVE To examine epithelial Na(+) channel (ENaC) expression in endometrium of overweight/obese women with polycystic ovary syndrome (PCOS) during the window of implantation, and to explore the mechanism linking leptin-mediated reduction of γ-ENaC to low endometrial receptivity. DESIGN Controlled, prospective, clinical, experimental study. SETTING University-based infertility center. PATIENT(S) Blood and endometrium samples were collected from 12 control women and 12 overweight/obese PCOS patients. Pregnancy outcomes were obtained from 245 women with male-factor infertility (533 cycles) and 57 infertile women with PCOS (120 cycles) who underwent intrauterine insemination. INTERVENTION(S) Human endometrial biopsies. MAIN OUTCOME MEASURE(S) Expression of ENaC mRNA and protein in endometrium. RESULT(S) The expression of γ-ENaC decreased in the secretory phase endometrium of PCOS patients who showed increased serum leptin levels. In cultured endometrial cells (Ishikawa cells), leptin dose-dependently down-regulated the expression of γ-ENaC and reduced the JAr spheroid attachment rate, which could be blocked by knockdown of STAT3, a signal in the pathway of leptin receptor activation. The overweight/obese PCOS patients with increased serum leptin levels showed a significantly increased biochemical pregnancy rate, suggesting that high leptin might attenuate endometrial receptivity and increase very early pregnancy loss. CONCLUSION(S) High serum leptin may reduce endometrial receptivity by activating the STAT3 signal pathway and down-regulating γ-ENaC expression in the endometrium. These results provide valuable new insights into the molecular mechanisms linking abnormal ENaC gene expression to early pregnancy loss in overweight/obese PCOS patients.

Abstract
BACKGROUND Small-conductance, Ca(2+)-activated K(+) channel 3 (SK3) has been shown to be expressed in porcine endometrium. However, the roles of SK3 in human endometrium during the menstrual cycle and early pregnancy are unknown. OBJECTIVE The objective of the study was to investigate the expression and function of SK3 in human endometrium and the mechanism involved. METHODS We determined the expression of SK3 in human endometrium by RT-PCR, Western blotting, and immunofluorescence. Using electrophysiological and fluorescent imaging techniques, we investigated the effects of SK3 on the membrane potential and the concentrations of cytosolic calcium, respectively. The effects of SK3 on endometrial thickness and pregnancy outcome were also investigated. Knockdown of endometrial SK3 was used to examine the effects of SK3 on cell migration, cytoskeleton formation, and calcium concentration in the cytosol. RESULTS SK3 channels are present in human endometrium. In vivo experimental and clinical data demonstrated that the reduced expression of SK3 was associated with a thin endometrium and unsuccessful pregnancy outcomes. Knockdown of human endometrial SK3 attenuated the rise in cytosolic calcium and membrane hyperpolarization induced by thapsigargin, a Ca(2+)-ATPase inhibitor, cell migration, and F-actin assembly. Knockdown of endometrial SK3 in mice also resulted in a thin endometrium and unsuccessful pregnancy outcome. CONCLUSIONS These observations demonstrate that SK3 channels are expressed in human endometrial cells. Reduced SK3 expression attenuates endometrial cell migration and is associated with unsuccessful pregnancy outcomes.

Abstract
The physiological mechanisms involved in isoproterenol (ISO)-induced chronic heart
failure (CHF) are not fully understood. In this study, we investigated local changes
in cardiac aldosterone and its synthase in rats with ISO-induced CHF, and evaluated
the effects of treatment with recombinant human brain natriuretic peptide (rhBNP).
Sprague-Dawley rats were divided into 4 different groups. Fifty rats received
subcutaneous ISO injections to induce CHF and the control group (n=10) received equal
volumes of saline. After establishing the rat model, 9 CHF rats received no further
treatment, rats in the low-dose group (n=8) received 22.5 μg/kg rhBNP and those in
the high-dose group (n=8) received 45 μg/kg rhBNP daily for 1 month. Cardiac function
was assessed by echocardiographic and hemodynamic analysis. Collagen volume fraction
(CVF) was determined. Plasma and myocardial aldosterone concentrations were
determined using radioimmunoassay. Myocardial aldosterone synthase (CYP11B2) was
detected by quantitative real-time PCR. Cardiac function was significantly lower in
the CHF group than in the control group (P<0.01), whereas CVF, plasma and
myocardial aldosterone, and CYP11B2 transcription were significantly higher than in
the control group (P<0.05). Low and high doses of rhBNP significantly improved
hemodynamics (P<0.01) and cardiac function (P<0.05) and reduced CVF, plasma and
myocardial aldosterone, and CYP11B2 transcription (P<0.05). There were no
significant differences between the rhBNP dose groups (P>0.05). Elevated cardiac
aldosterone and upregulation of aldosterone synthase expression were detected in rats
with ISO-induced CHF. Administration of rhBNP improved hemodynamics and ventricular
remodeling and reduced myocardial fibrosis, possibly by downregulating CYP11B2
transcription and reducing myocardial aldosterone synthesis.

Abstract
CONTEXT There are increasing concerns that a disrupted endocrine environment may disturb the growth of the fetus. Assisted reproductive technology (ART) situates gamete/embryo in a supraphysiological estradiol (E2) environment and, thus, provides an ideal model to investigate this problem. OBJECTIVE Our objective was to investigate whether the maternal high-E2 environment in the first trimester increases the risks of low birth weight (LBW) and small-for-gestational-age (SGA) birth. METHODS In total, 8869 singletons born after fresh embryo transfer (ET) (n = 2610), frozen ET (n = 1039), and natural conception (NC) (n = 5220) and their mothers were included. Birth weight, LBW, SGA, and maternal serum E2 levels were investigated. RESULTS The mean serum E2 levels of women undergoing fresh ET at 4 and 8 weeks of gestation were significantly higher than those of the women undergoing frozen ET and the women with NC (P < .01). Serum E2 levels of women undergoing fresh ET at 4 and 8 weeks of gestation were positively correlated to those on the day of human chorionic gonadotropin (hCG) administration (r = 0.5 and r = 0.4, respectively; P < 0.01). The birth weight after fresh ET was significantly lower than that after frozen ET and NC (P < 0.01), with increased incidence of LBW and SGA (P < .05). Furthermore, in the fresh ET group, singletons of mothers with high E2 levels (≥10460 pmol/L on the day of hCG administration) had higher risks of LBW (P < .01) and SGA (P < .01) than those with low E2 levels, and maternal serum E2 level on the day of hCG administration negatively correlated with the birth weight (P < .01). CONCLUSIONS The maternal high-E2 environment in the first trimester is correlated with increased risks of LBW and SGA. Evaluation of serum E2 before ET should be adopted to reduce the possibility of high E2 exposure to gamete/embryo.

Abstract
OBJECTIVE To study the effect of desogestrel and ethinyl estradiol (DEE) pre-treatment combined with gonadotropin releasing hormone agonist (GnRH-a) stimulation in in vitro fertilization-embryo transplantation (IVF-ET). METHODS A retrospective analysis was performed in 101 infertile women who received a short protocol of GnRH-a for IVF-ET treatment from June 2004 to June 2007 in the Reproductive Medicine Center of First Affiliated Hospital of Wenzhou Medical College. Patients had been pre-treated with oral contraceptive pill (OCP) for two months before GnRH-a combined with recombinant follicle stimulation hormone (r-FSH) treatment (study group, n = 42) or had not been pretreated with OCP (control group, n = 59). A statistical analysis of two groups was carried out for the assessment of ovulation stimulating effect of OCP and its influence on the IVF. RESULTS Serum FSH was significantly decreased after OCP in the study group. Twelve pregnancies were obtained including 1 case of spontaneous abortion at 7 weeks in the study group, and 11 pregnancies were obtained including 2 cases of spontaneous abortion during 7 -9 weeks in control group. The clinical pregnancy rates in the study group (23%, 12/53) was higher than that in the control group (17%, 11/63), but the differences were not significant (P > 0.05). The miscarriage rate in the study group (8%, 1/12) was lower than that in the control group (18%, 2/11), however no significant differences were found between them (P > 0.05). The cycle cancellation rate in patients of the study group (5%, 3/56)was significantly lower than that in patients of the control group (17%, 13/76, P < 0.05). The differences between patients of the two groups with respect to age, basal level of FSH and luteinizing hormone (LH), antral follicle counts, the mean number of oocyte retrieval, the days of stimulation, total dose of r-FSH used, fertilization rate and embryo cleavage rate, however were insignificant. CONCLUSION OCP pretreatment combined with short protocol of GnRH-a stimulation in IVF could significantly decrease the cycle cancellation rate, with a declining miscarriage rate and increasing pregnancy rate.

Abstract
UNLABELLED It has been shown that arsenic trioxide (ATO) induced apoptosis in human nasopharyngeal carcinoma cells and inhibited the growth of nasopharyngeal carcinoma xenografts (NPCX) in nude mice. AIM The present study was designed to determine whether ATO at the non-toxic dose level could potentiate the therapeutic effectiveness of radiation therapy in nasopharyngeal carcinoma, using a BALB/C nude mouse xenograft model. METHODS The mice bearing NPCX were treated with radiation alone (2, 4, and 6 Gy), ATO alone (4 mg/kg/day x 6 days), and ATO plus radiation at the same dosage levels. Time of tumor growth delay (defined as the time necessary for the tumor to grow four-fold of its initial volume after, compared with untreated tumors) and toxic effects were determined. RESULTS The low dose ATO alone has no pronounced effects on tumor growth delay compared to untreated control. However, compared with radiation alone, the combined regimen delayed the tumor growth by 2-10 days and had no significant toxic effects such as the liver function damage. CONCLUSIONS Combination of ATO at non-toxic dose level and radiation has synergistic effects on tumor growth inhibition in vivo and is well tolerated.

Abstract
Hailey-Hailey disease (HHD; MIM 16960) is a rare autosomal dominant hereditary disorder characterized by recurrent eruption of vesicles and bullae, predominantly involving the body folds. It is caused by heterozygous mutations in the ATP2C1 gene, encoding the human secretory pathway Ca2+/Mn2+-ATPase protein 1 (hSPCA1). When we studied Chinese patients with HHD, we found two different heterozygous mutations, Q506X and G353V, the former previously reported in a Hungarian patient, and the latter being a novel mutation. In a 38-year-old patient from a four-generation pedigree with a 3-year history of severe recurrent blisters, we identified a C-->T transition at nucleotide 1696, c(1696C-->T), in exon 17 of ATP2C1, resulting in a nonsenes mutation, Gln506X, which resulted in a premature termination codon. In the second patient, who represented a occurrence of sporadic Hailey-Hailey disease, a G-->T transversion of nucleotide, c(G1238T), in exon 13 of ATP2C1 was detected, which resulted in a Gly353-->Val amino acid substitution (G353V). Our molecular findings further demonstrate that the mutational events in the human ATP2C1 gene encoding the hSPCA1 pump play an important role in the pathogenesis of HHD.

Abstract
DNA methylation is known to play an important role in the regulation of gene expression in eukaryotes. The rice cultivar Wase Aikoku 3 becomes resistant to the blight pathogen Xanthomonas oryzae pv. oryzae at the adult stage. Using methylation-sensitive amplified polymorphism (MSAP) analysis, we compared the patterns of cytosine methylation in seedlings and adult plants of the rice cultivar Wase Aikoku 3 that had been inoculated with the pathogen Xanthomonas oryzae pv. oryzae, subjected to mock inoculation or left untreated. In all, 2000 DNA fragments, each representing a recognition site cleaved by either or both of two isoschizomers, were amplified using 60 pairs of selective primers. A total of 380 sites were found to be methylated. Of these, 45 showed differential cytosine methylation among the seedlings and adult plants subjected to different treatments, and overall levels of methylation were higher in adult plants than in seedlings. All polymorphic fragments were sequenced, and six showed homology to genes that code for products of known function. Northern analysis of three fragments indicated that their expression varied with methylation pattern, with hypermethylation being correlated with repression of transcription, as expected. The results suggest that significant differences in cytosine methylation exist between seedlings and adult plants, and that hypermethylation or hypomethylation of specific genes may be involved in the development of adult plant resistance (APR) in rice plants.

Abstract
AIM To compare the postnatal development of brainstem auditory evoked potential (BAEP) with that of middle latency response (MLR) in rats. METHODS The postnatal development of BAEP and MLR had been studied continuously for 10 weeks in the same groups of rat Pups. RESULTS BAEP and MLR emerged at day 14 and 17 respectively. The peak latencies of BAEP's waves shortened systematically with age, especially during 3-4 weeks. The peak latency of wave I reached adult value at day 29, and the peak latencies of the rest waves reached adult ones at day 70. However, the peak latencies of wave Po and Na in the first time evoked MLR had already been at adult values. Though the peak latencies of wave Pa, Nb and Pb also shortened with age, they reached adult ones quickly at day 20-23. The wave amplitudes of BAEP's wave I ,III, IV and MLR's wave Nb, Pb increased quickly with age during 3-4 weeks. Their peak values were much bigger than adult ones and then decreased gradually. CONCLUSION The postnatal development of BAEP and MLR proceeded in a similar way in rats, but the peak latencies of MLR reached adult values much earlier than that of BAEP.

Abstract
Neuroanatomical asymmetries are known to be present in the human brain, and loss of reversal of these asymmetries, particularly through changes in the left temporal lobe, have been found in the brains of patients with schizophrenia. In addition to disturbed neuroanatomical asymmetries, disturbed neurochemical asymmetries have also been reported in the brains of patients with schizophrenia. However, in the temporal lobe, the laterality of most of these neurochemical changes has not been specifically evaluated. Few neurochemical studies have addressed left-right differences in the superior temporal gyrus (STG). A deteriorated serotonin2A receptor-G protein qalpha (Gqalpha)-phosphoinositide-specific phospholipase C beta1(PLC beta1) cascade has been found in the left, but not right, STG of patients with schizophrenia. Not only neuroanatomical but also neurochemical evidence supports the loss or reversal of normal asymmetry of the temporal lobe in schizophrenia, which might be due to a disruption of the neurodevelopmental processes involved in hemispheric lateralization.

Abstract
We have cloned murine genomic and complementary DNA that is equivalent to the human ABO gene. The murine gene consists of at least six coding exons and spans at least 11 kilobase pairs. Exon-intron boundaries are similar to those of the human gene. Unlike human A and B genes that encode two distinct glycosyltransferases with different donor nucleotide-sugar specificities, the murine gene is a cis-AB gene that encodes an enzyme with both A and B transferase activities, and this cis-AB gene prevails in the mouse population. Cloning of the murine AB gene may be helpful in establishing a mouse model system to assess the functionality of the ABO genes in the future.

Abstract
BACKGROUND Abnormalities in types of neurotransmitter signaling that are coupled with phosphoinositide-specific phospholipase C (PLC) have previously been reported in brains from patients with schizophrenia. PLC, a main component of this pathway, may be affected in schizophrenia. METHODS We immunoquantified PLC beta 1, gamma 1 and delta 1 in the left prefrontal cortex and superior temporal cortex, nucleus accumbens and amygdala, and in the right superior temporal cortex of postmortem brains obtained from a total of 19 patients with schizophrenia and a total of 27 controls. RESULTS PLC beta 1 immunoreactivities were increased in the particulate fraction from the prefrontal cortex (by 64%), although they were decreased in the particulate fraction from the left superior temporal cortex (by 28%), as compared with the values in controls. There was no difference in PLC beta 1 immunoreactivities in the nucleus accumbens, the amygdala or the right superior temporal cortex between schizophrenic patients and controls. PLC gamma 1 and delta 1 immunoreactivities did not differ between the two groups in any of the regions studied. CONCLUSIONS Changes in PLC beta 1 immunoreactivities in the prefrontal and superior temporal cortex of patients with schizophrenia may reflect abnormalities in neurotransmissions via receptors that are coupled with the Gq alpha-PLC beta 1 cascade.

Abstract
PURPOSE Immunohistochemical procedures were employed to test the hypothesis that cytokines such as interleukin-1beta (IL-1beta) and interleukin-6 (IL-6) are involved in AIDS-related optic neuropathy and to determine the primary cell types involved. METHODS Fixed sections of six human HIV-1 infected optic nerves were immunostained for the presence of IL-1beta and IL-6, using horseradish peroxidase and diaminobenzidine as markers. RESULTS IL-1beta and IL-6 were found in astrocytes, macrophages, microglia, and endothelial cells. The great majority of astrocytes demonstrated strong immunoreactivity. CONCLUSION Our findings support the premise that IL-1beta and IL-6 are significant pro-inflammatory mediators in AIDS-related optic neuropathy. This finding supports the theory that HIV infection stimulates the release of IL-1beta and IL-6 in astrocytes, macrophages, and endothelial cells in the optic nerve which ultimately leads to demyelination, astrogliosis, and neuronal destruction.

Abstract
PURPOSE To examine the microvascular changes in the retrobulbar optic nerve in idiopathic intracranial hypertension (PTC). METHODS Both optic nerves from a 29-year-old man with a two year history of PTC were examined histologically and morphometrically. A semi-automated image analysis system and paraphenylenediamine (PPD) stain were employed to resolve sufficiently the microvascular images for counts and measurement. RESULTS There were 150 vessels distributed in the optic nerves which revealed the following: The average lumen of the vessels in outer sectors were larger than those of the inner sector vessels (168.17 microns 2 vs. 46.99 microns 2; p = 0.0338; OD; and 251.96 microns 2 vs. 130.02 microns 2; p = 0.029; OS) while in the normal control optic nerve the outer and inner area lumens were reversed in size-differential, but this did not show a statistical difference. The thickness of the PTC optic nerve vessel walls in the outer sectors was also greater than that of the walls in the inner sectors (4.95 microns vs. 2.67 microns; p = 0.013; OD and 5.25 microns vs. 3.34 microns; p = 0.019; OS); the same measurements in the normal optic nerve showed a reversed ratio, which was opposite that of the experimental group and but not statistically different. CONCLUSION This pattern of microvascular changes is consistent with the selective axonal loss in the peripheral area of each optic nerve as much more severe than that in the inner sectors.

Abstract
Protein phosphatase 2A (PP2A) is an abundant, multifunctional serine/threonine-specific phosphatase that stimulates simian virus 40 DNA replication. The question as to whether chromosomal DNA replication also depends on PP2A was addressed by using a cell-free replication system derived from Xenopus laevis eggs. Immunodepletion of PP2A from Xenopus egg extract resulted in strong inhibition of DNA replication. PP2A was required for the initiation of replication but not for the elongation of previously engaged replication forks. Therefore, the initiation of chromosomal DNA replication depends not only on phosphorylation by protein kinases but also on dephosphorylation by PP2A.

Abstract
BACKGROUND We examined possible abnormalities in neural structural proteins that may underlie morphometric changes reported in the left superior temporal cortices (Brodmann's area 22) of schizophrenics. METHODS Particulate proteins of the superior temporal cortices taken at autopsy from 11 schizophrenic and 9 control brains were fractionated by gel electrophoresis. Target proteins, identified by reading their amino acid sequences, were immunoquantified using the specific antibody. RESULTS Amino acid sequences of the 150-kDa proteins on sodium dodecyl sulfate/polyacrylamide gel electrophoresis, which were significantly increased on the left side of schizophrenic superior temporal cortices, revealed that they were proteolytic fragments of the alpha subunit of fodrin, a major cytoskeletal protein underlying the plasma membrane. Immunoquantification using the specific antibodies against alpha and beta subunits of fodrin indicated that there exist concomitant decreases in the full-length 240-kDa form and increases in the 150-kDa form of alpha-fodrin with no changes of the 235-kDa form of beta-fodrin in the left superior temporal cortices of the schizophrenic brains. CONCLUSIONS The findings may be a possible molecular basis for linking morphometric changes to neurochemical pathophysiology in schizophrenia.

Abstract
PURPOSE Both in vitro and in vivo studies have implicated a role for tumor necrosis factor (TNF-alpha) in the pathology of demyelinating diseases. The purpose of this study was to address the hypothesis that TNF-alpha is a mediator of AIDS-related optic nerve injury and to determine the cell types involved in the proliferation of TNF-alpha in the AIDS optic nerve. METHODS Ten optic nerves from seven patients with AIDS, and three from persons who were HIV negative were stained, using the indirect immunoperoxidase method. Six of the ten AIDS optic nerves were positive for cytomegalovirus (CMV), but the remainder did not have abnormal fundus findings. RESULTS In all the optic nerves from AIDS patients with or without CMV retinitis, the vast majority of astrocytes stained strongly for TNF-alpha. Microglial cells (MPS-derived macrophages) varied from not staining to staining strongly positive for TNF-alpha. However, oligodendrocytes were not labeled positively for TNF-alpha. Some endothelial cells also stained for TNF-alpha. Examination of normal optic nerves and controls did not reveal any cell type that stained positively for TNF-alpha. CONCLUSIONS The present study supports the contention that TNF-alpha is a major mediator of AIDS-associated optic neuropathy. HIV infection induces the production of TNF-alpha in macrophages and astrocytes, which probably causes demyelination and other neuronal damage.
