Abstract
BACKGROUND A possible role of PM2.5 components on ovarian reserve has not been adequately unexplored. OBJECTIVE To evaluate the association between PM2.5 components and women' ovarian reserve over critical exposure periods in northern China, where the level of air pollution is among the nation's highest. METHODS We included 15,102 women with serum anti-Müllerian hormone (AMH) measurements from the Center for Reproductive Medicine of Shandong University during 2015-2019. Concentrations of PM2.5 and its five major components (0.1° × 0.1°), including sulfate, nitrate, ammonium, organic matter, and black carbon, were assigned to each residential address. Multivariable linear mixed effect models combined with constituent-residual models were performed to estimate the effect sizes of essential components over six short- to long-term exposure periods. RESULTS The strength of association was stronger during the process from primary to small antral follicle compared with other longer windows. For every interquartile range increase in PM2.5 mass was associated with - 8.7% (95%CI: -12.3%, -4.9%) change in AMH and the effect size was greatest for sulfate. Women with the lower level of attained education and those living inland were more susceptible compared with other population subgroups. CONCLUSION Exposure to specific components of air pollution during critical exposure windows is associated with a decline in ovarian reserve. These data add to the growing body of evidence that environmental factors have adverse effects on reproductive health, particularly for vulnerable population subgroups.

Abstract
A large proportion of miscarriages are classified as unexplained miscarriages since no cause is identified. No reliable biomarkers or treatments are available for these pregnancy losses. While our transcriptomic sequencing has revealed substantial upregulation of miR-146b-5p in unexplained miscarriage villous tissues, its role and associated molecular processes have yet to be fully characterized. Our work revealed that relative to samples from normal pregnancy, miR-146b-5p was significantly elevated in villous tissues from unexplained miscarriage patients and displayed promising diagnostic potential. Moreover, miR-146b-5p agomir contributed to higher rates of embryonic resorption in ICR mice. When overexpressed in HTR-8/SVneo cells, miR-146b-5p attenuated the proliferative, invasive, and migratory activity of these cells while suppressing the expression of MMP9 and immune inflammation-associated cytokines, including IL1B, IL11, CXCL1, CXCL8, and CXCL12. Conversely, inhibition of its expression enhanced proliferation, migration, and invasion abilities. Mechanistically, IL-1 receptor-associated kinase-1 and a disintegrin and metalloproteinase 19 were identified as miR-146b-5p targets regulating trophoblast function, and silencing IL-1 receptor-associated kinase-1 had similar effects as miR-146b-5p overexpression, while IL-1 receptor-associated kinase-1 overexpression could partially reverse the inhibitory impact of this microRNA on trophoblasts. miR-146b-5p may inhibit trophoblast proliferation, migration, invasion, and implantation-associated inflammation by downregulating IL-1 receptor-associated kinase-1 and a disintegrin and metalloproteinase 19, participating in the pathogenesis of miscarriage and providing a critical biomarker and a promising therapeutic target for unexplained miscarriage.

Abstract
OBJECTIVE Although the mechanism underlying preeclampsia (PE) has been widely explored, the mechanisms related to senescence have not yet been fully revealed. Therefore, we investigated the role of the miR-494/longevity protein Sirtuin 1 (SIRT1) axis in PE. METHODS Human placental tissue was obtained from severe preeclampsia (SPE) (n = 20) and gestational age-matched normotensive pregnancies (n = 20), and senescence-associated β-galactosidase (SAβG) and SIRT1 expression levels were measured. The TargetScan and miRDB databases predicted candidate miRNAs targeting SIRT1, and intersected with differentially expressed miRNAs in the GSE15789 dataset (p < 0.05, |log2FC|≥1.5). Subsequently, we showed that miRNA (miR)-494 expression was significantly elevated in SPE, revealing miR-494 as a candidate SIRT1-binding miRNA. A dual-luciferase assay confirmed the targeting relationship between miR-494 and SIRT1. The senescence phenotype, migration, cell viability, reactive oxygen species (ROS) production levels and inflammatory molecule expression levels were measured after miR-494 expression was altered. We conducted a rescue experiment using SIRT1 plasmids to further demonstrate the regulatory relationship. RESULTS SIRT1 expression was lower(p < 0.01) and miR-494 expression was higher (p < 0.001) in SPE, and SaβG staining showed premature placental aging in SPE (p < 0.001). Dual-luciferase reporter assays revealed that miR-494 targeted SIRT1. Compared to control cells, HTR-8/SVneo cells with upregulation of miR-494 had remarkably downregulated SIRT1 expression (p < 0.001), more SAβG-positive cells (p < 0.001), cell cycle arrested (p < 0.05), and upregulated P21 and P16 expression (p < 0.01). miR-494 overexpression also decreased HTR-8/SVneo cell migration (p < 0.05) and ATP synthesis (p < 0.001), increased ROS levels (p < 0.001), and upregulated NLRP3 and IL-1β expression (p < 0.01). SIRT1-overexpressing plasmids partially reversed the effects of miR-494 overexpression in HTR-8/SVneo cells. CONCLUSION The miR-494/SIRT1 interaction plays a role in the mechanism of premature placental aging in PE patients.

Abstract
OBJECTIVE This study aimed to assess the effectiveness of Mersilene tape versus alternative suture types in prolonging singleton pregnancies as well as other pregnancy and neonatal outcomes, in cases of history-, ultrasound-, and exam-indicated cervical cerclage. METHODS A systematic review was conducted to identify relevant studies comparing different suture types in cervical cerclage procedures. The primary outcome of interest was preterm birth (PTB) rate < 37, <35, < 28, and < 24 weeks. Statistical analyses were performed to determine the relationship between suture type and various outcomes. RESULTS A total of five studies, including three randomized controlled trials (RCTs) and two retrospective studies, with a combined participation of 2325 individuals, were included. The pooled analysis indicated no significant association between suture type and PTB at less than 37 weeks of gestation (RR: 1.02, 95% CI: 0.65-1.60, p < 0.01, I2 = 74%). Women who received Mersilene tape had a higher risk of PTB at 34-37 weeks (RR: 2.62, 95% CI: 1.57-4.37, p = 0.69, I2 = 0%), but a lower risk of PTB at less than 34 weeks (RR: 0.43, 95% CI: 0.28-0.66, p = 0.66, I2 = 46%). No statistically significant differences were observed for PTB before 28 weeks (RR: 1, 95% CI: 0.65-1.53, p = 0.70, I2 = 0%), before 24 weeks (RR: 0.86, 95% CI: 0.60-1.23, p = 0.33, I2 = 0%), incidence of chorioamnionitis (RR: 0.97, 95% CI: 020-4.83, p < 0.01, I2 = 95%), neonatal intensive care unit (NICU) admission (RR: 0.79, 95% CI: 0.28-2.22, p = 0.08, I2 = 67%) and neonatal death (RR: 1.00, 95% CI: 0.42-2.35, p = 0.17, I2 = 48%). CONCLUSION Our findings suggest that Mersilene tape does not reduce the risk of PTB before 37, 28 or 24 weeks. We observed higher risk of preterm birth between 34 and 37 weeks with Mersilene tape but lower incidence before 34 weeks, a period with higher neonatal morbidity and mortality. Due to the limited number of studies, our results and their clinical significance should be interpreted with caution.

Abstract
Background Recurrent pregnancy loss defined as the occurrence of two or more pregnancy losses before 20-24 weeks of gestation, is a prevalent and significant pathological condition that impacts human reproductive health. However, the underlying mechanism of RPL remains unclear. This study aimed to investigate the biomarkers and molecular mechanisms associated with RPL and explore novel treatment strategies for clinical applications. Methods The GEO database was utilized to retrieve the RPL gene expression profile GSE165004. This profile underwent differential expression analysis, WGCNA, functional enrichment, and subsequent analysis of RPL gene expression using LASSO regression, SVM-RFE, and RandomForest algorithms for hub gene screening. ANN model were constructed to assess the performance of hub genes in the dataset. The expression of hub genes in both the RPL and control group samples was validated using RT-qPCR. The immune cell infiltration level of RPL was assessed using CIBERSORT. Additionally, pan-cancer analysis was conducted using Sangerbox, and small-molecule drug screening was performed using CMap. Results A total of 352 DEGs were identified, including 198 up-regulated genes and 154 down-regulated genes. Enrichment analysis indicated that the DEGs were primarily associated with Fc gamma R-mediated phagocytosis, the Fc epsilon RI signaling pathway, and various metabolism-related pathways. The turquoise module, which showed the highest relevance to clinical symptoms based on WGCNA results, contained 104 DEGs. Three hub genes, WBP11, ACTR2, and NCSTN, were identified using machine learning algorithms. ROC curves demonstrated a strong diagnostic value when the three hub genes were combined. RT-qPCR confirmed the low expression of WBP11 and ACTR2 in RPL, whereas NCSTN exhibited high expression. The immune cell infiltration analysis results indicated an imbalance of macrophages in RPL. Meanwhile, these three hub genes exhibited aberrant expression in multiple malignancies and were associated with a poor prognosis. Furthermore, we identified several small-molecule drugs. Conclusion This study identifies and validates hub genes in RPL, which may lead to significant advancements in understanding the molecular mechanisms and treatment strategies for this condition.

Abstract
Objective This study aimed to examine the mediating role of fear of missing out (FoMO) and the moderating role of resilience in the association between social media use and negative emotions among medical college students in China during the COVID-19 pandemic. Participants and Methods A cross-sectional study design was conducted, medical college students from Qiqihar Medical University, China participated in the study. A total of 470 medical college students were recruited voluntarily to complete questionnaires on social media use, FoMO, resilience, and negative emotions. Results Social media use was positively associated with FoMO and negative emotions among medical students (p < 0.01). The total effect of social media use on negative emotions was significant (β = 1.101, SE = 0.079, p < 0.001). Social media use had no significant direct effect on negative emotions (β = 0.168, SE = 0.096, p > 0.05), but it had an indirect effect on negative emotions via mediation of FoMO (β = 0.933, SE = 0.106, 95% CI: 0.731 to 1.149). Moreover, resilience had a significant moderating effect on the relationship between FoMO and negative emotions (β = -0.021, SE = 0.005, 95% CI: -0.032 to -0.012). FoMO had a significant positive predictive effect on negative emotions at both levels of resilience (low resilience individuals: β = 1.079, SE = 0.076, p < 0.001; high resilience individuals: β = 0.212, SE = 0.094, p < 0.05). Conclusion Social media use and FoMO may be risk factors for increased negative emotions, and resilience should be considered in prevention and intervention strategies designed to mitigate negative emotions among medical college students.

Abstract
BACKGROUND Lack of evidence exists on whether air pollution exposure may affect ovarian reserve, especially for Chinese women. OBJECTIVES To explore the association between exposure to various air pollutants and anti-Müllerian hormone (AMH), a predictor of ovarian reserve, over different exposure windows in Shandong Province, China. METHODS We enrolled 18,878 women who had AMH measurements in the Center for Reproductive Medicine, Shandong University during 2010-2019. Daily average concentrations of ambient particulate matter with diameters ≤1 μm/2.5 μm/10 μm (PM1, PM2.5, and PM10), nitrogen dioxide (NO2) and ozone (O3) were developed at a spatial resolution of 0.01° × 0.01°, and assigned to the residential addresses. Three exposure windows were considered, i.e., the process from primary to small antral follicle stage (W1), from primary to secondary follicle stage (W2), and from secondary to small antral follicle stage (W3). The air pollution-AMH association was fitted using the multivariable linear mixed effect model with adjustment for potential confounders. Stratified analyses were performed by age group, overweight status, residential region, and educational level. RESULTS The level of AMH changed by -8.8% (95% confidence interval (CI): -12.1%, -5.3%), -2.1% (95% CI: -3.5%, -0.6%), -1.9% (95% CI: -3.3%, -0.5%), and -4.5% (95% CI: -7.1%, -1.9%) per 10 μg/m3 increase in PM1, PM2.5, PM10, and NO2, respectively, during W1. The effect estimates were significant during W2 for PM1, PM2.5 and NO2 while minimal association was observed in W3. Greater vulnerability for certain air pollutants were observed for women who lived in inland areas and were less educated. CONCLUSIONS We found that ovarian reserve was negatively associated with air pollution exposure for women, particularly from the primary to secondary follicle stage. The effect estimate increased by the reduction in the diameter of PMs, which also varied across population sub-groups.

Abstract
Objectives The prognosis of endometrial cancer (EC) is significantly affected by tumor infiltration and metastasis. Cortactin (CTTN) regulates infiltration and metastasis in other tumors. Studies on the role and mechanism of CTTN in EC are limited and further studies are needed. Materials and Methods Quantitative PCR and immunohistochemistry were used to detect Ras-associated C3 botulinum toxin substrate 1 (Rac1) and CTTN in EC and normal tissues. The relationship between the expression of these two genes and their prognostic factors was analyzed. A CTTN-RNAi lentiviral system was constructed and transfected into EC cells. Migration and invasion were evaluated by scratch assay, transwell migration, and invasion assays. Pseudopodia formation was observed by immunofluorescence staining. Western blotting was performed to detect the expression of Rac1. Results The expression levels of Rac1 and CTTN in EC tissues were significantly higher than those in normal tissues. In the EC group, Rac1 and CTTN levels were correlated. The protein expression levels of Rac1 and CTTN were related to myometrial invasion and stage. After CTTN knockdown, the migration rate, invasiveness, and migratory ability of EC cells decreased significantly. Lamellipodia was observed to disappear with the appearance of blebs. Rac1 protein expression was decreased after CTTN knockdown. Conclusion CTTN may promote the invasion and migration of EC by lamellipodia. This effect may be related to the regulation of Rac1 by CTTN.

Abstract
Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Abstract
BACKGROUND Spontaneous abortions (SA) is amongst the most common complications associated with pregnancy in humans, and the underlying causes cannot be identified in roughly half of SA cases. We found miR-135a-5p to be significantly upregulated in SA-associated villus tissues, yet the function it plays in this context has yet to be clarified. This study explored the function of miR-135a-5p and its potential as a biomarker for unexplained SA. METHOD RT-qPCR was employed for appraising miR-135a-5p expression within villus tissues with its clinical diagnostic values being assessed using ROC curves. The effects of miR-135a-5p in HTR-8/SVneo cells were analyzed via wound healing, Transwell, flow cytometry, EdU, CCK-8, and tube formation assays. Moreover, protein expression was examined via Western blotting, and interactions between miR-135a-5p and PTPN1 were explored through RIP-PCR, bioinformatics analyses and luciferase reporter assays. RESULTS Relative to normal pregnancy (NP), villus tissue samples from pregnancies that ended in unexplained sporadic miscarriage (USM) or unexplained recurrent SA (URSA) exhibited miR-135a-5p upregulation. When this miRNA was overexpressed in HTR-8/SVneo cells, their migration, proliferation, and cell cycle progression were suppressed, as were their tube forming and invasive activities. miR-135a-5p over-expression also downregulated the protein level of cyclins, PTPN1, MMP2 and MMP9. In RIP-PCR assays, the Ago2 protein exhibited significant miR-135a-5p and PTPN1 mRNA enrichment, and dual-luciferase reporter assays indicated PTPN1 to be a bona fide miR-135a-5p target gene within HTR-8/SVneo cells. CONCLUSION miR-135a-5p may suppress trophoblast migratory, invasive, proliferative, and angiogenic activity via targeting PTPN1, and it may thus offer value as a biomarker for unexplained SA.

Abstract
The involvement of circRNAs in β-thalassemia and their actions on fetal hemoglobin (HbF) is unclear. Here, the circRNAs in β-thalassemia carriers with high HbF levels were comprehensively analyzed and compared with those of healthy individuals. Differential expression of 2183 circRNAs was observed and their correlations with hematological parameters were investigated. Down-regulated hsa-circRNA-100466 had a strong negative correlation with HbF and HbA2. Bioinformatics was employed to construct a hsa-circRNA-100466‑associated competing endogenous RNA (ceRNA) network to identify hub genes and associated miRNAs. The hsa-circRNA-100466▁miR-19b-3p▁SOX6 pathway was identified using both present and previously published data. The ceRNA network was verified by qRT-PCR analysis of β-thalassemia samples, RNA immunoprecipitation of K562 cell lysates, and dual-luciferase reporter analysis. qRT-PCR confirmed that hsa-circRNA-100466 and SOX6 were significantly down-regulated, while miR-19b-3p was up-regulated. Hsa-circRNA-100466, miR-19b-3p, and SOX6 were co-immunoprecipitated by anti-argonaute antibodies, indicating involvement with HbF induction. A further dual-luciferase reporter assay verified that miR-19b-3p interacted directly with hsa-circRNA-100466 and SOX6. Furthermore, spearman correlation coefficients revealed their significant correlations with HbF. In conclusion, a novel hsa-circRNA-100466▁miR-19b-3p▁SOX6 pathway was identified, providing insight into HbF induction and suggesting targets β-thalassemia treatment.

Abstract
OBJECTIVE To construct a polylactic acid-glycolic acid-polyethylene glycol (PLGA-PEG) nanocarrier (N-Pac-CD133) coupled with a CD133 nucleic acid aptamer carrying paclitaxel for eliminating lung cancer stem cells (CSCs). METHODS Paclitaxel-loaded N-Pac-CD133 was prepared using the emulsion/solvent evaporation method and characterized. CD133+ lung CSCs were separated by magnetic bead separation and identified for their biological behaviors and gene expression profile. The efficiency of paclitaxel-loaded N-Pac-CD133 for targeted killing of lung cancer cells was assessed in vitro. SCID mice were inoculated with A549 cells and received injections of normal saline, empty nanocarrier linked with CD133 aptamer (N-CD133), paclitaxel, paclitaxel-loaded nanocarrier (N-Pac) or paclitaxel-loaded N-Pac-CD133 (n=8, 5 mg/kg paclitaxel) on days 10, 15 and 20, and the tumor weight and body weight of the mice were measured on day 40. RESULTS Paclitaxel-loaded N-Pac-CD133 showed a particle size of about 100 nm with a high encapsulation efficiency (>80%) and drug loading rate (>8%), and was capable of sustained drug release within 48 h. The CD133+ cell population in lung cancer cells showed the characteristic features of lung CSCs, including faster growth rate (30 days, P=0.001) and high expressions of tumor stem cell markers OV6(P < 0.001), CD133 (P=0.001), OCT3/4 (P=0.002), EpCAM (P=0.04), NANOG (P=0.005) and CD44 (P=0.02). Compared with N-Pac and free paclitaxel, paclitaxel-loaded N-Pac-CD133 showed significantly enhanced targeting ability and cytotoxicity against lung CSCs in vitro (P < 0.001) and significantly reduced the formation of tumor spheres (P < 0.001). In the tumor-bearing mice, paclitaxel-loaded N-Pac-CD133 showed the strongest effects in reducing the tumor mass among all the treatments (P < 0.001). CONCLUSION CD133 aptamer can promote targeted delivery of paclitaxel to allow targeted killing of CD133+ lung CSCs. N-Pac-CD133 loaded with paclitaxel may provide an effective treatment for lung cancer by targeting the lung cancer stem cells.

Abstract
Neural tube defects (NTDs) constitute the second most common congenital malformation of the central nervous system. The pathogenesis of NTDs is not entirely clear. In recent years, microRNAs (miRNAs) have become a hot spot in genetic and developmental biology research. The present study aimed to explore the potential role of miRNA-26a in NTDs and the underlying pathogenesis thereof. First, we found significantly increased miRNA-26a expression in fetuses with NTDs (p < 0.0001), which significantly downregulated EphA2 and ERK1 mRNA and protein expression levels in fetuses with NTDs compared to normal controls (p < 0.01). In addition, a dual-luciferase reporter assay showed that miR-26a negatively regulated EphA2 by directly binding with the 3'-untranslated region of EphA2. Second, the upregulation of miRNA-26a expression increased caspase 3 and 9 protein expression levels (p < 0.01) and decreased EphA2 mRNA and protein expression levels (p < 0.01), as well as ERK1 and SRF protein expression levels (p < 0.01) in mouse neural stem cells (NE-4C) and human astroblastoma cells (U87MG). Furthermore, the upregulation of miRNA-26a inhibited cell proliferation and enhanced apoptosis of NE-4C and U87MG cells (p < 0.05). Similar results were observed with the MAPK inhibitor PD98059 (p < 0.01). These results suggest that miR-26a targets EphA2, modulates phosphorylation of the MAPK/ERK (MEK) pathway, regulates SRF, and participates in regulating nervous cell proliferation and apoptosis. Dysregulation of the aforementioned mechanism may be involved in the pathogenesis of NTDs.

Abstract
AIM Hemoglobin Bart's hydrops fetalis syndrome (BHFS) is the most severe form of α-thalassemia. Histological alternations can be observed in placenta, but placental transcriptome profile and circular RNAs have not been studied in this disease. The aim of this study was to define the placental transcriptional changes and find relevant circular RNAs in BHFS. METHODS We performed high-throughput RNA sequencing to detect placental samples from fetuses affected by BHFS (n = 5) and normal fetuses (NF, n = 5), quantitative reverse transcription polymerase chain reaction (RT-qPCR), and Sanger sequencing to validate the differentially expressed circRNAs and their potentially related miRNAs (BHFS, n = 22; NF, n = 11). Bioinformatics methods were performed for further analysis. RESULTS Our results showed 152 differentially expressed genes (DEGs), 112 circRNAs, and 45 microRNAs that were differentially expressed. DEGs were found to be involved in Gene Ontology terms related to gas transport, cell adhesion, oxidative stress, organ development, hemopoiesis, and others. RT-qPCR results showed that hsa_circ_0003961 and hsa_circ_0006687 were upregulated (p < 0.05). The competing endogenous RNA and co-expression networks showed that hsa_circ_0003961 and hsa_circ_0006687 were connected with 3 miRNAs and some DEGs, including cell adhesion genes (e.g., CLDN19), hemoglobin related genes (e.g., SOX6 and HBZ) and angiogenesis related genes (e.g., EPHB2). Downregulations of hsa-miR-1299 and hsa-miR-625-5p in ceRNA network were also validated by RT-qPCR. Gene set enrichment analysis results for the two circRNAs showed that some gene sets associated with cell adhesion, hematopoietic system and apoptosis were significantly enriched. CONCLUSIONS Our study characterized the placental transcriptome of BHFS. The circRNAs hsa_circ_0003961 and hsa_circ_0006687 in placenta may be relevant to BHFS.

Abstract
Nifedipine is a typical dihydropyridine calcium antagonist, and large doses of intake can cause poisoning. This article retrospectively analyzed the clinical data of a patient with nifedipine poisoning complicated with paralytic intestinal obstruction admitted to the First Affiliated Hospital of Jilin University in October 2020. When the patient was admitted to the hospital, the symptoms of poisoning were decreased blood pressure and shock, followed by severe paralytic intestinal obstruction. Finally, after active hemoperfusion combined with hemofiltration and symptomatic supportive treatment, the patient's condition improved and was discharged. There was no discomfort in the follow-up 2 months later.

Abstract
This study aimed to screen the potential candidate genes and relevant biological markers associated with gastrointestinal metaplasia that progresses to gastric cancer (GIM-GC). Microarray datasets (GSE78523) were downloaded from the GEO database. Differentially expressed genes (DEGs) between GIM-GC samples and healthy controls were identified. GO and KEGG pathway enrichment analyses were performed. STRING and Cytoscape were used to identify significant module and hub genes. Survival analysis was applied to identify key genes. A Venn diagram was built to find hub DEGs that differed in all three relevant comparisons (GIM-GC vs. healthy controls vs. GIM-NoGC). The clinical characteristics of the hub DEGs were evaluated using the Cancer Genome Atlas dataset. The study found 257 DEGs (217 upregulated and 40 downregulated). The upregulated DEGs were enriched in regulation of microvillus length and phospholipid binding and were components of the apical plasma membrane. Downregulated DEGs were involved in digestion and hormone activity and were found in the extracellular space. Fat digestion and absorption as well as gastric acid secretion were the pathways enrichment. The most important gene modules related mainly to O-glycan processing, extracellular exosome, hormone activity, and vitamin and fat digestion and absorption. Eleven hub genes were identified, of which APOB, FABP1, CDX2, GCG, HNF4A, SLC26A3, CFTR, MUC5AC, OLFM4, and SI were related to the prognosis. Olfactomedin-4 (OLFM4) was the most relevant DEG to identify GIM-GC. In conclusion: DEGs and hub genes are helpful to understand the molecular mechanisms of GIM-GC. OLFM4 may be a biological marker for GIM-GC.

Abstract
BACKGROUND We designed a meta-analysis to evaluate the clinical significance and efficacy of circulating noncoding RNAs (ncRNAs) in the early prediction of preeclampsia. METHODS PubMed, Embase and the Cochrane Library were used to search for literature. The combined prediction performance was evaluated by calculating the area under the summary receiver operator characteristic (SROC) curve. The potential sources of heterogeneity were analysed by meta-regression analysis and subgroup analysis. All statistical analyses and mapping were performed by RevMan 5.3 and Stata 12.0. RESULTS A total of 41 studies from 14 articles, including 557 preeclampsia patients and 842 controls, were included in our meta-analysis. All studies collected blood before onset. NcRNAs in blood performed relatively well in predicting preeclampsia. The combined sensitivity was 0.71, the specificity was 0.84, and the area under the SROC curve (AUC) was 0.86. Peripheral blood mononuclear cell (PBMC) samples showed the best diagnostic accuracy. The combined AUC was 0.93. Combined detection was better than single detection, and miRNA was better than circRNA. The heterogeneity of the study was determined by sample size, lncRNA characteristics, lncRNA source and race. CONCLUSION Circulating ncRNAs can be valuable biomarkers used as candidates for noninvasive early predictive biomarkers of preeclampsia and have great clinical application prospects. The clinical value of ncRNAs needs to be tested by further multicentre, comprehensive and prospective studies, and the test criteria should be established.

Abstract
Objective: To understand the cognition and related factors on the use of HIV non-occupational post-exposure prophylaxis (nPEP) among men who have sex with men (MSM). Methods: The snowballing method was applied to recruit research subjects who were ≥18 years old, had sex with men in the past three months, and were aware of nPEP in MSM groups in Beijing, Shenzhen, and Kunming from March 15 to April 14, 2019. Data on social demographics, behavioral characteristics, basic knowledge of nPEP, consultation, and using nPEP were collected through "i guardian Platform". The logistic regression model was used to analyze the related factors affecting the use of nPEP. Results: Among 1 809 investigated, 39.8% (720 persons) were aware of the basic knowledge of nPEP, 33.4% (605 persons) had consulted nPEP, and 15.0% (271 persons) had used nPEP. In addition, multivariate logistic regression analysis showed that factors as whether to have sex with men infected with HIV in the last three months (OR=2.58, 95%CI: 1.64-4.07), the frequency of HIV testing in the past year (OR=2.47, 95%CI: 1.28-5.11), nPEP knowledge awareness (OR=0.70, 95%CI: 0.49-0.99), whether to consult nPEP (OR=70.98, 95%CI: 40.51-136.83) were related to the use of nPEP. Conclusions: MSM still have poor cognition of nPEP. It is necessary to strengthen the publicity and education of nPEP in MSM and promote the use of nPEP after HIV exposure as soon as possible.

Abstract
Endometrial hyperplasia (EH) is a precursor for endometrial cancer (EC). However, biomarkers for the progression from EH to EC and standard prognostic biomarkers for EC have not been identified. In this study, we aimed to identify key genes with prognostic significance for the progression from EH to EC. Weighted-gene correlation network analysis (WGCNA) was used to identify hub genes utilizing microarray data (GSE106191) downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified from the Uterine Corpus Endometrial Carcinoma (UCEC) dataset of The Cancer Genome Atlas database. The Limma-Voom R package was applied to detect differentially expressed genes (DEGs; mRNAs) between cancer and normal samples. Genes with |log2 (fold change [FC])| > 1.0 and p < 0.05 were considered as DEGs. Univariate and multivariate Cox regression and survival analyses were performed to identify potential prognostic genes using hub genes overlapping in the two datasets. All analyses were conducted using R Bioconductor and related packages. Through WGCNA and overlapping genes in hub modules with DEGs in the UCEC dataset, we identified 42 hub genes. The results of the univariate and multivariate Cox regression analyses revealed that four hub genes, BUB1B, NDC80, TPX2, and TTK, were independently associated with the prognosis of EC (Hazard ratio [95% confidence interval]: 0.591 [0.382–0.912], p = 0.017; 0.605 [0.371–0.986], p = 0.044; 1.678 [1.132–2.488], p = 0.01; 2.428 [1.372–4.29], p = 0.02, respectively). A nomogram was established with a risk score calculated using the four genes’ coefficients in the multivariate analysis, and tumor grade and stage had a favorable predictive value for the prognosis of EC. The survival analysis showed that the high-risk group had an unfavorable prognosis compared with the low-risk group (p < 0.0001). The receiver operating characteristic curves also indicated that the risk model had a potential predictive value of prognosis with area under the curve 0.807 at 2 years, 0.783 at 3 years, and 0.786 at 5 years. We established a four-gene signature with prognostic significance in EC using WGCNA and established a nomogram to predict the prognosis of EC.

Abstract
OBJECTIVE To investigate the value of quantitative detection of ITGA4 and SFRP2 gene methylation in stool DNA for the early diagnosis and prognostic evaluation of colorectal tumors. OBJECTIVE Real-time PCR was used for quantitative assessment of ITGA4 and SFRP2 gene methylation levels in stool samples of 85 patients with colorectal cancer, 65 patients with colorectal adenoma and 40 healthy subjects. OBJECTIVE The 3 groups were comparable for age and gender composition. Methylated ITGA4 and SFRP2 promoters were detected in 48.2% and 62.4% of patients with colorectal cancer, respectively, with a combined positivity of 81.2%. ITGA4 and SFRP2 promoter methylation was detected in 23.1% and 43.1% of patients with colorectal adenoma, respectively, with a combined positivity of 69.2%. The positivity rates of ITGA4 and SFRP2 methylation were significantly higher in patients with colorectal cancer than in those with colorectal adenoma (P < 0.001; P= 0.001) and healthy subjects (P < 0.001; P < 0.001). In colorectal cancer group, ITGA4 and SFRP2 promoter methylation levels were correlated with postoperative tumor recurrence in colorectal cancer group, and the relapse-free survival rate was significantly lower in positive patients for ITGA4 and SFRP2 promoter methylation than in the negative patients (P=0.0002; P=0.007). Multivariate analysis with the COX proportional hazard regression model showed that methylation of ITGA4 and SFRP2 gene promoters (P=0.01) and the degree of tumor differentiation (P=0.03) were associated with the recurrence of colorectal cancer, and were independent risk factors for the recurrence of colorectal cancer. OBJECTIVE Combined detection of ITGA4 and SFRP2 gene methylation levels in stool DNA can improve the early diagnosis rate of colorectal tumor. ITGA4 and SFRP2 promoter methylation and the degree of tumor differentiation are independent risk factors for colorectal cancer recurrence.

Abstract
Abstract Objective To retrospectively analyze the characteristics of the traumatic rupture of intracranial internal carotid artery in order to provide reference for forensic expertise examination and identification. Methods A total of 11 autopsy cases of traumatic rupture of intracranial internal carotid artery were collected. The gender, age, cause of injury, blood loss on the scene, location of internal carotid artery rupture, hardening degree of the rupture of the wall, brain injury, blood ethanol content and cause of death were also recorded. Results All 11 cases died on the scene, of which 7 died from traffic accidents, 2 falls from height and 2 from bare handed injuries. None of the 11 victims suffered serious head and body surface injury. The internal carotid artery rupture in the 9 cases of traffic injury and fall from height injury occurred in the cavernous segment. In all these cases, there were transverse fractures of the middle cranial fossa with the carotid sulcus involved, and minor intracranial hemorrhage and brain contusion. In 2 cases of bare handed injuries, internal carotid artery rupture occurred in the ophthalmic artery segment, accompanied by fatal intracranial hemorrhage and diffuse axonal injury, but no skull fracture. All 11 cases showed full-thickness rupture of the vessel wall, and the long axis of the wounds was perpendicular to those of the artery. Conclusion The incidence of intracranial internal carotid artery rupture in high-energy trauma events such as traffic accidents and high falls deserves attention. Injuries of the cavernous segment or ophthalmic segment might be more common. The main injury mechanism of intracranial internal carotid artery rupture might be that the blood vessels were pulled and the bone fragments caused damage.

Abstract
Legionella pneumophila cell surface hydrophobicity and charge are important determinants of their mobility and persistence in engineered water systems (EWS). These surface properties may differ depending on the growth phase of L. pneumophila resulting in variable adhesion and persistence within EWS. We describe the growth-dependent variations in L. pneumophila cell surface hydrophobicity and surface charge using the microbial adhesion to hydrocarbon assay and microelectrophoresis, respectively, and their role in cell adhesion to stainless steel using a quartz crystal microbalance with dissipation (QCM-D) monitoring instrument. We observed a steady increase in L. pneumophila hydrophobicity during their lifecycle in culture media. Cell surfaces of stationary phase L. pneumophila were significantly more hydrophobic than their lag and midexponential counterparts. No significant changes in L. pneumophila cell surface charge were noted. Morphology of L. pneumophila remained relatively constant throughout their lifecycle. In the QCM-D study, lag and exponential phase L. pneumophila weakly adhered to stainless steel surfaces resulting in viscoelastic layers. In contrast, stationary phase bacteria were tightly and irreversibly bound to the surfaces, forming rigid layers. Our results suggest that the stationary phase of L. pneumophila would highly favour their adhesion to plumbing surfaces and persistence in EWS.

Abstract
As a chaperone protein of progesterone receptor (PR), FK-506 Binding Protein 52 (FKBP52) can enhance the activity of PR, but the mechanism of FKBP52 affecting PR expression levels is difficult to clarify. Here, we report a novel in vitro model of ectopic endometrial stromal cells (ESCM) established through the primary culture method of endometrial stromal cells, which is used to study the details of relationship between FKBP52 abnormality and PR expression level in endometriosis (Ems). At the same time, the clinical study of the relationship between FKBP52 and PR expression levels in endometriosis patients was used to verify our conclusions. The results showed that the expression levels of PR-A mRNA and protein in endometriosis are positively correlated with FKBP52 and the abnormality of FKBP52 leads to the decrease of PR-B mRNA and protein expression. When FKBP52 was deleted or reduced, the expression levels of m RNA and protein of PR-A and PR-B have decreased leading to the proliferation of ectopic endometrium cells (ESC) and the occurrence of endometriosis, which is consistent with the expression levels of clinical endometriosis patients and fully confirms our conclusions and reliability of the model, and has great guiding significance for the research of Ems disease occurrence mechanism and clinical treatment.

Abstract
Abstract Objective To provide reference for medical and health services and forensic expertise, the causes and manners of death of psychiatric patients were analyzed retrospectively. Methods A total of 105 autopsy cases of psychiatric patients accepted and settled by Institute of Forensic Science of Criminal Investigation Police University of China from 2004 to 2019 were collected. The cases were divided into four groups: disease death, suicidal death, accidental death and homicidal death. The common causes of death of each group were statistically analyzed and the differences in age, disease duration, body mass index (BMI) and gender among the groups were assessed. Results Of the 105 cases, 60 were male and 45 were female, the course of psychosis was (12.9±10.4) years, the age of the deceased was (51.3±11.4) years, and 61.0% was schizophrenic. There were 50 cases (47.6%) in the disease death group, in which the psychiatric patients were the oldest and had the longest course of psychosis and lowest BMI. Pulmonary thromboembolism, respiratory infections, and cardiogenic disease were the most common causes of death in the group. There were 26 accidental deaths (24.8%), among which traffic accidents were the most common cause of death. There were 15 homicidal deaths (14.3%), all of which were male, with craniocerebral injury being the most common cause of death. There were 14 suicidal deaths (13.3%). In suicidal death group, the age of the deceased was the youngest, the course of psychosis was the shortest and falling from the height was the most common way to commit suicide. Conclusion Understanding the common causes of death of psychiatric patients may contribute to developing measures to reduce the mortality rate of the population. It is necessary to investigate the age, course of psychosis and gender of the deceased when assessing the manner of death.

Abstract
AIM To explore the regulatory role and molecular mechanism of lncRNA-LINC01279 in endometriosis (EMs). METHODS Between September 2018 and July 2019, 20 EMs patients and 20 healthy subjects were recruited to detect the expression of lncRNA-LINC01279 in EMs and in normal endometrium via qRT-PCR. Autograft was used to establish EMs models on Spraque-Dawley (SD) rats, which was followed by taking volume measurements of EMs endometrium and observing pathological changes in the morphology of EMs via hematoxylin and eosin (H&E) staining. The qRT-PCR technique was further carried out to determine mRNA expression of lncRNA-LINC01279 and HOXA10 in the serum of EMs rats and LINC01279 shRNA-transfected rats, while the protein expression of HOXA10 was determined using a Western blot. RESULTS EMs patients presented with upregulation of lncRNA-LINC01279 and downregulation of HOXA10 (p < 0.01 or 0.001). Online predictions further revealed that lncRNA-LINC01279 regulated the expression of HOXA10 via miRNA-135b. In EMs models, it was observed that there were a significantly enlarged endometrium and poor pathological morphology, significant upregulation of lncRNA-LINC01279, and downregulation of miR-135b and HOXA10 in serum (p < 0.05, 0.01 or 0.001). In the lncRNA-LINC01279 shRNA group, EMs rats, following treatment, had a sharp decrease in the volume of EMs endometrium, and an improvement in pathological morphology, while lncRNA-LINC01279 was downregulated, with upregulation of miR-135b and HOXA10 (p < 0.05, 0.01 or 0.001). CONCLUSION LncRNA-LINC01279, by the mechanism of targeting miR-135b, has the potential to downregulate the expression of HOXA10, and therefore, can promote the development and progression of EMs.

Abstract
Objective: To analyze the association of D-dimer levels, inflammatory indicators, cytokine abnormality, and disease severity in COVID-19 severe/critical type patients. Methods: The medical records of 41 patients were collected from a single center in Wuhan from February 8, 2020 to March 25, 2020. The patients were divided into severe type group (28 patients) and critical type group (13 patients) . The levels of D-dimer, WBC, ANC, PCT, hsCRP, IL-2R, IL-6, IL-8, and TNF-α were compared among patients with different clinical types of COVID-19 infection. Moreover, the changes in the cytokines were analyzed in patients with different D-dimer levels. And, the levels of D-dimer, IL-2R, IL-6, IL-8, and TNF-α before and after anticoagulant therapy were assessed. Statistical analyses were performed using Student t test, Mann-Whitney U test, and Chi-square test. Results: Among the 41 patients, 23 were men (56.1%) and 18 were women (43.9%) ; the median patient age was 57 y. The age of the critical type patients [ (61.1±10.4) y] was higher than that of severe type patients [ (52.8±11.7) y]; the difference was significant (t=-2.264, P=0.032) . The proportion of critical type patients with chronic diseases, especially hypertension, cardiovascular disease, and cerebrovascular disease, was higher as compared to that in those with severe type patients; the differences were significant (all P<0.05) . The prevalence of dyspnea, sweats, and fatigue symptoms in the critical type patients was higher than that in those with severe type disease; the differences were significant (χ(2)=14.898, 6.972, 7.823; P<0.001, 0.008, 0.005) . The levels of D-dimer, WBC, ANC, PCT, hsCRP, and IL-8 in critical type patients were higher than those in severe type patients; the differences were significant (all P<0.05) . The levels of IL-2R, IL-8, and TNF-α in patients with abnormal D-dimer were higher as compared to those in patients with normal D-dimer levels; the differences were significant (all P<0.05) . Eight patients were treated with prophylactic anticoagulation; the levels of D-dimer, IL-2R, IL-6 and IL-8 after anticoagulant therapy were lower than those before treatment. Conclusions: COVID-19 critical type patients have more serious coagulation-immune dysfunction and dynamic monitoring of D-dimer and cytokines levels helps in identifying critical type patients as early as possible; anticoagulant therapy may improve the patient's condition by correcting coagulation-immune dysfunction.

Abstract
Objective: To understand the hepatitis C diagnosis type, progression and treatment in medical institutions. Methods: Monitoring posts were set up in the secondary and tertiary-level hospitals in some parts of the country. Reported infectious diseases cases of hepatitis C in sentinel hospitals during the three consecutive years from 2017 to 2019 were investigated to understand their general demographic characteristics, diagnosis, liver fibrosis degree, and treatment. The diagnosis, treatment and related factors were analyzed by chi square test and trend. Results: A total of 16 241 cases of hepatitis C were investigated in three years. Among them, 7 538 cases were clinically diagnosed (46.41%) and 8703 cases (53.59%) were confirmed as hepatitis C. Among the confirmed cases, 60 cases (0.69%) were acute and 8643 cases (99.31%) were chronic. In the past three years, the proportion of cases diagnosed by liver diseases related departments decreased from 62.23% to 40.01%, while the proportion of medical and surgical cases of non-liver diseases increased from less than 30% to nearly 60%. The proportion of confirmed cases in secondary hospitals (26.27%) was significantly lower than that in tertiary hospitals (62.48%), and the difference was statistically significant (χ (2) = 1594.833, P < 0.001). There were also differences in the proportion of confirmed cases in different regions (P < 0.001). The cases with FIB-4 > 3.25 accounted for 35.78%, and the proportion was increased significantly with age (χ (2) trend = 1159.624, P < 0.001). The average proportion of antiviral treatment was less than 10%, and the proportion of antiviral treatment in secondary hospitals was very low (2.13%); however, the proportion of liver-protective monotherapy treatment was decreased from 30.40% in 2017 to 11.14% in 2019, and the difference was statistically significant (P < 0.001). Conclusion: The large-scale screening of hepatitis C by medical institutions is increasing year by year, but only about half of the cases can be diagnosed, and the diagnostic capacity of secondary hospitals is particularly unsatisfactory. Most of the confirmed cases are chronic hepatitis C, and more than one third of them have abnormal liver fibrosis indicators, and the proportion increases with age. The proportion of antiviral treatment for hepatitis C is lower in secondary than tertiary-level hospitals. Therefore, there is an urgent need to raise the attention of both parties (doctors and patients) to enhance diagnostic capabilities and expand the coverage of antiviral treatment for hepatitis C.

Abstract
HCV prevalence among people who inject drugs (PWID) is up to 67%. PWID is a population that needs priority attention to achieve the World Health Organization's goal of eliminating viral hepatitis as a public health threat by 2030. Although the SVR of HCV patients treated with direct-acting antiviral drugs (DAAs) can reach over 95%, especially in medical practice, there are still major obstacles to PWID treatment, because PWID is usually accompanied with concurrent infection, multiple-genotype infections, low compliance, substance abuse, methadone maintenance therapy, and risky behavior and re-infection conditions. Therefore, physicians often concern that these factors will affect the treatment efficacy, and refuse to provide hepatitis C treatment in PWID. This article reviews the relevant studies status and effects of hepatitis C treatment in PWID with different infection states and special behavior characteristics, and further highlights that the multidisciplinary cooperation for hepatitis C treatment in PWID is safe and effective, and can ensure treatment compliance.

Abstract
Evidence indicates that microRNAs (miRNAs) play essential roles in early embryonic development. The miRNA-518 family is a special biomarker of the placenta, and miRNA-518b is abnormally expressed in placental tissue in preeclampsia. Early growth response protein 1 (EGR1), a zinc finger transcriptional factor, plays an essential role in regulating cell differentiation, angiogenesis, and migration. Moreover, earlier studies have shown that EGR1 protein plays a key role in implantation. However, little is known about the role of miR-518b and EGR1 on early embryonic arrest (EEA) in humans. In our study, increased miR-518b along with decreased EGR1 was found in human villus tissues with EEA. Furthermore, we demonstrated by luciferase assay that miR-518b is a direct regulator of EGR1. After comparing the effect of silencing EGR1, vascular endothelial growth factor (VEGF) individually, and EGR1/VEGF in combination, we found that EGR1 can inhibit migration and angiogenesis of HTR-8 SVneo cells by decreasing the VEGF expression. Hypoxia plays an initial role in early embryonic development, and we found that hypoxia reduces the expression of miR-518b and increases the expression of EGR1 and VEGF to facilitate migration and angiogenesis in a hypoxic model of HTR-8/SVneo cell line. Our findings provide new insights into the role of miR-518b in EEA and implicate the potential application of miR-518b in the diagnosis and development of intervention for EEA.

Abstract
AIM The objective of this study was to investigative genetic and environmental factors that contribute to caries susceptibility among adolescents in south China. MATERIALS AND METHODS A cross-sectional study was conducted among 1055 adolescents aged 13-14 years old in south China. The International Caries Detection and Assessment System (ICDAS) was used to identify caries. Environmental variables were analysed by regression models. Twenty-three single nucleotide polymorphisms (SNPs) in 14 genes were identified from saliva samples. Regression analysis was used for the evaluation of effects of SNP markers using the minor allele as the effect allele. RESULTS Our results suggest that gender, Cariostat score and Plaque Index were associated with dental caries. After the adjustment by age and gender, the G allele in AMBN (rs13115627) nominally was a protective factor for caries under additive model (P=0.028; OR=0.782; 95% CI, 0.627-0.974). However, the association did not meet the Bonferroni correction significance cut-off for multiple testing. CONCLUSION Gender, Cariostat score and Plaque Index were associated with dental caries in this population. No selected SNPs showed a significant association with dental caries under either additive model or dominance model.

Abstract
INTRODUCTION Idiopathic polyhydramnios (IPH) is an abnormal increase in amniotic fluid volume (AFV). This condition has unknown etiologies and is associated with various adverse pregnancy outcomes including maternal and fetal complication. This study aims to establish a comparative proteome profile for the human amniotic fluid (AF) of IPH and normal pregnancies and identify the responsible mediators and pathways that regulate AFV. METHODS We first employed coupled isobaric tags for relative and absolute quantitation (iTRAQ) proteomics and bioinformatics analysis to examine the differentially expression proteins (DEPs) in the AF of IPH and normal pregnancies. Second, CUL5, HIP1, FSTL3, and LAMP2 proteins were selected for verification in amnion, chorion, and placental tissues by Western blot analysis. RESULTS We identified 357 DEPs with 282 upregulated and 75 downregulated. Bioinformatics analysis revealed that cell, cellular process, and binding were the most enriched Gene Ontology terms. Amoebiasis, hematopoietic cell lineage, and NF-kappa B signaling pathway were the top significant pathways. In the verification procedure, FSTL3 protein had a highly significant expression in the amnion, chorion, and placentas of IPH and normal AFV groups (p < 0.05). DISCUSSION Our results provide new insights into idiopathic polyhydramnios and offer fundamental points for future studies on AFV.

Abstract
OBJECTIVE In invasive aspergillosis (IA), monitoring response to antifungal treatment is challenging. We aimed to explore if routine blood parameters help to anticipate outcomes following IA. METHODS Post hoc secondary analysis of two multicenter randomized trials was performed. The Global Comparative Aspergillosis Study (GCA, n = 123) and the Combination Antifungal Study (CAS, n = 251) constituted the discovery and validation cohorts respectively. The outcome measures were response to treatment and survival to 12 weeks. Interval platelet, galactomannan index (GMI) and C-reactive protein (CRP) levels prior and during antifungal treatment were analysed using logistic regression, Kaplan-Meier survival and receiver operating characteristic (ROC) analyses. RESULTS The 12-week survival was 70.7% and 63.7% for the GCA and CAS cohorts respectively. In the GCA cohort, every 10 × 109/L platelet count increase at week 2 and 4 improved 12-week survival odds by 6-18% (odds ratio (OR) 1.06-1.18, 95% confidence interval (CI) 1.02-1.33). Survival odds also improved 13% with every 10 mg/dL CRP drop at week 1 and 2 (OR 0.87, 95% CI 0.78-0.97). In the CAS cohort, week 2 platelet count was also associated with 12-week survival with 10% improved odds for every 10 × 109/L platelet increase (OR, 1.10, 95% CI 1.04-1.15). A GMI drop of 0.1 unit was additionally found to increase the odds of treatment response by 3% at the baseline of week 0 (OR 0.97, 95% CI 0.95-0.99). Week 2 platelet and CRP levels performed better than GMI on ROC analyses for survival (area under ROC curve 0.76, 0.87 and 0.67 respectively). A baseline platelet count higher than 30 × 109/L clearly identified patients with >75% survival probability. CONCLUSIONS Higher serial platelets were associated with overall survival while GMI trends were linked to IA treatment response. Routine and simple laboratory indices may aid follow-up of response in IA patients.

Abstract
Extensive Monte Carlo simulations have been performed on an Ising ferromagnet under conditions that would lead to complete wetting in a semi-infinite system. We studied an L×L×D slab geometry with oppositely directed surface fields so that a single interface is formed and can undergo a localization-delocalization transition. Under the chosen conditions the interface position is, on average, in the middle of the slab, and its fluctuations allow a sensitive test of predictions that the effective interactions between the interface and the confining surfaces are nonlocal. The decay of distance dependent correlation functions are measured within the surface, in the middle of the slab, and between middle and the surface for slabs of varying thickness D. From Fourier transforms of these correlation functions a nonlinear correlation length is extracted, and its behavior is found to confirm theoretical predictions for D>6 lattice spacings.

Abstract
Objective: To compare the time and spatial distribution of hepatitis C and HIV/AIDS cases and its correlation, in China from 2012 to 2017. Methods: Data on reported hepatitis C and HIV/AIDS cases was gathered from the Direct Reporting System of Infectious Diseases Information Network in China, 2012 to 2017 while annually collected provincial data was based on the date of review and current address. Correlation of the data was analyzed, using both simple correlation and linear regression methods. Results: The number of reported cases of hepatitis C remained stable in China, in 2012-2017, with the number of annual reported cases as 201 622, 203 155, 202 803, 207 897, 206 832 and 214 023, respectively. The number of reported cases on HIV/AIDS showed a steady growing trend, from 82 434, 90 119, 103 501, 115 465, 124 555 to 134 512. However, the numbers of hepatitis C and HIV/AIDS cases were in the same, top six provinces: Henan, Guangdong, Xinjiang, Guangxi, Hunan and Yunnan. Results from the simple correlation analysis indicated that there was a positive correlation (r>0.5, P<0.01) existed between the above-said two kinds of cases at the provincial level in China, in 2012-2017. Again, results from the linear regression analysis also showed that the correlation coefficient r(s) and year was strongly correlated (r=0.966) while r(s) had been linearly increasing with time. Conclusions: Our data showed that there were temporal and spatial correlations existed between the reported cases of hepatitis C and HIV/AIDS at the provincial level, suggesting that relevant prevention and control programs be carried out in areas with serious epidemics. Combination of the two strategies should be encouraged, especially on prevention and treatment measures related to blood transmission.

Abstract
RATIONALE The purpose of this case report was to raise awareness regarding endometriosis on the surface of the uterus mimicking malignant tumor and thus manage it accurately. PATIENT CONCERNS A 40-year-old Asian woman with a 2-year history of lower abdomen pain was admitted to our department with elevated serum cancer antigen (CA) 125 level, weight loss, and pelvic mass from 20 days previously. Magnetic resonance imaging revealed a high volume of effusion in the pelvic cavity, an irregular occupying lesion on the surface of the fundus of the uterus, and multiple nodules. DIAGNOSES Postoperative pathology confirmed the diagnosis of endometriosis. INTERVENTIONS Diagnostic laparoscopy revealed large crunchy tissue and soft nodules on the surface of the posterior wall of the uterus and approximately 2000 mL of bloody ascites. The result of the frozen-section analysis of the tissue on the surface of the uterus indicated endometriosis. The surgical procedure was converted to laparotomy due to bleeding after biopsy. OUTCOMES The patient's recovery was uneventful. Three months after the operation, the patient had a good general state without periodic pain, and the CA125 level returned to normal. LESSONS A large mass occurring in the pelvic cavity could be indicative of endometriosis, especially if accompanied by a history of period pain. Preoperative positron emission tomography may increase the accuracy of the diagnosis.

Abstract
Objective: To understand the prevalence of hepatitis C virus (HCV) infection in 5 populations in China during 2016-2017 and provide evidence for the estimation of prevalence trend of hepatitis C and evaluation on the prevention and control effect. Methods: A total of 87 national sentinel surveillance sites for hepatitis C were set up in 31 provinces (autonomous regions and municipalities) of China to obtain the information about HCV infection prevalence in 5 populations, including volunteer blood donors, people receiving physical examination, patients receiving invasive diagnosis and treatment, patients receiving hemodialysis, and clients visiting family planning outpatient clinics. From April to June, 2016 and 2017, cross-sectional surveys were repeatedly conducted in the 5 populations and blood samples were collected from them for HCV antibody detection. Results: In 2016, 86 sentinel sites completed the surveillance (one sentinel site was not investigated), and 115 841 persons were surveyed. The overall HCV positive rate was 0.38% (442/115 841, 95%CI: 0.23%-0.53%). In 2017, all the 87 sentinel sites completed the surveillance, and 120 486 persons were surveyed. The overall HCV positive rate was 0.37% (449/120 486, 95%CI: 0.23%-0.52%). In 2016 and 2017, the anti-HCV positive rates were 4.46% (223/5 005, 95%CI: 2.18%-6.73%) and 4.39% (216/4 919, 95%CI: 2.29%-6.50%) respectively in hemodialysis patients, 0.85% (44/5 200, 95%CI: 0.27%-1.42%) and 0.70% (36/5 150, 95%CI: 0.15%-1.24%) respectively in patients receiving invasive diagnosis and treatment and remained to be ≤0.25% in volunteer blood donors, people receiving physical examination and clients visiting family planning outpatient clinics. Results for the comparison of the anti-HCV positive rates in the 5 populations indicated that the differences were significant (F=23.091, P<0.001 in 2016 and F=20.181, P<0.001 in 2017). Conclusions: Data from the sentinel surveillance of HCV infection on prevalence in China showed that the anti-HCV positive rates varied in the 5 populations during 2016-2017. The anti-HCV positive rate appeared the highest in the hemodialysis patients, followed by that in the patients receiving invasive diagnosis and treatment, and the prevalence of HCV infection in other 3 populations were at low levels.

Abstract
Abstract
Background: Iron oxide nanoparticles (NPs) have been used for a variety of in-vivo and ex-vivo applications within the biomedical sciences. Moreover, when intended for clinical in-vivo applications, NPs need to meet rigorous requirements to ensure safety as well as bio-functionality including blood circulation time and specificity for cellular targets. PrecisonMRX® NPs are extensively characterized superparamagnetic NPs composed of a 25nm magnetite cores that are currently employed in a variety of in-vivo applications including non-invasive/in vivo diagnosis of cancer, Magnetic Particle Imaging, MRI, and magnetic hyperthermia.
Objective: Here we report on the extensive pre-clinical development and functionality of antibody (Herceptin)-conjugated NPs for in-vivo and ex-vivo detection of HER2+ tumor cells by Magnetic Relaxometry (MRX).
Results: We observed: 1) specific binding and detection of HER2 positive tumor cells in-vitro; 2) specific detection of HER2+ tumors in mice; 3) binding and amplitude of magnetic signal to be proportional to the level of HER2 expression in-vitro and in-vivo; 4) the nanoconstruct remains stable in circulation; 5) the particles do not induce a pro-inflammatory response nor activate complement; 6) the particles are biodegradable; and do not induce acute or delayed signs of morbidity in mice.
Conclusion: Precision MRX® nanoparticles offer great clinical promise including the in- vivo detection of tumor cells by magnetic relaxometry. Given the stability and safety of these NPs, our pre-clinical results support progressing to clinical testing. A first-in human ex-vivo clinical research study design and strategy will be discussed.

Abstract
Early Embryonic Arrest (EEA) is one of the major causes of female infertility. Genetic factors including specific genes and miRNAs may play pivotal roles on EEA. However, it is not well defined what genes and micro RNAs participate the pathophysiological alterations of EEA. In this work, we compared the Transcriptome -Seq and microRNA profiles from three pairs of villi (three EEA patients and three normal pregnancy, NP). We first confirmed the array data by qPCR with ten randomly selected differentially expressed genes and ten differentially expressed miRNAs in villi from 20 EEA and 20 NP controls. We next applied Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathway analysis and found that these differentially expressed genes enriched in the PI3K-Akt signaling pathway, Jak-STAT signaling pathway, MAPK signaling pathway, Complement and coagulation cascades, Hypertrophic cardiomyopathy (HCM), Dilated cardiomyopathy (DCM). Interestingly, hsa-miR-6515-5p and its target genes NLRP3, UGP2 may regulate the Immune system and carbohydrate metabolism. Hsa-miRNA 518 and its target gene EGR1 may regulate cell proliferation, angiogenesis, and cell apoptosis to impact early embryonic development. Moreover, novel-m0045-5p and its target gene RMDN3 may regulate microtubule formation on the development of EEA. Our research provides novel biomarkers for EEA and establishes a foundation for further study of the mechanism of EEA.

Abstract
UNLABELLED Pseudovitamin D-deficiency rickets is a rare disease which is caused by CYP27B1. In this study, we identified 9 mutations in 7 PDDR patients. In addition, we observed the response to long-term treatment of calcitriol in 15 Chinese patients with PDDR, which showed that the biochemical abnormalities had been corrected satisfactorily after 1-year treatment. INTRODUCTION Pseudovitamin D-deficiency rickets is a rare autosomal recessive disorder resulting from a defect in 25-hydroxyvitamin D 1α-hydroxylase, which is encoded by CYP27B1. The purpose of this study was to identify the CYP27B1 mutations and investigate the response to long-term treatment of calcitriol in Chinese patients with PDDR. METHODS We investigated CYP27B1 mutations in seven individuals from six separate families. To investigate the response to long-term (13 years) treatment with calcitriol in PDDR patients, we additionally collected clinical data of eight families from our previous report and analyzed their biochemical parameter and radiographic changes during the treatment. RESULTS Nine different mutations were identified: two novel missense mutations (G194R, R259L), three novel and one reported deletion mutations (c1442delA, c1504delA, c311-321del, and c. 48-60del), two novel nonsense mutations (c.85G>T, c.580G>T), and a reported insertion mutation (c1325-1332insCCCACCC). The statistical analysis revealed that parathyroid hormone (PTH) and ALP significantly decreased after 6-month and 1-year treatment with calcitriol respectively. Urine calcium was measured in all the patients without kidney stones being documented. After 6-year treatment, the radiographic abnormalities had also been improved. Two patients who had reached their final height are both with short stature (height Z-score below - 2.0). CONCLUSIONS We identified seven novel mutations of CYP27B1 gene in seven Chinese PDDR families. Our findings revealed after 1-year treatment of active vitamin D3, PTH and ALP significantly decreased. The correction of the biochemical abnormalities had not improved the final height satisfactorily.

Abstract
Interactions between germline-encoded natural killer (NK) cell receptors and their respective ligands on tumorigenic or virus-infected cells determine NK cell cytotoxic activity and/or cytokine secretion. NK cell cytokine responses can be augmented in and can potentially contribute to multiple sclerosis (MS), an inflammatory disease of the central nervous system focused upon the oligodendrocytes (OLs). To investigate mechanisms by which NK cells may contribute to MS pathogenesis, we developed an in vitro human model of OL-NK cell interaction. We found that activated, but not resting human NK cells form conjugates with, and mediate cytotoxicity against, human oligodendrocytes. NK cells, when in conjugate with OLs, rapidly synthesize and polarize IFN-γ toward the OLs. IFN-γ is capable of reducing myelin oligodendrocyte and myelin associated glycoproteins (MOG and MAG) content. This activity is independent of MHC class-I mediated inhibition via KIR2DL1, but dependent upon the interaction between NK cell-expressed KIR2DL4 and its oligodendrocyte-expressed ligand, HLA-G. NK cells from patients with MS express higher levels of IFN-γ following conjugation to OLs, more actively promote in vitro reduction of MOG and MAG and have higher frequencies of the KIR2DL4 positive population. These data collectively suggest a mechanism by which NK cells can promote pathogenic effects upon OLs.
