Abstract
Purpose Imipenem is one of the very few effective options for treating Mycobacterium abscessus (M. abscessus) infections; the development of imipenem resistance is a major health concern. Materials and Methods The susceptibility of 194 clinical M. abscessus isolates to imipenem was determined. The ability of imipenem to synergize with N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN), a zinc chelator and a metallo-β-lactamases (MBLs) inhibitor, to inhibit M. abscessus growth was also assessed. Results M. abscessus exhibited an elevated resistance to imipenem (MIC50 = 16 mg/L, MIC90 = 64 mg/L). A combination of TPEN and imipenem synergized to inhibit the growth of 100% of imipenem-resistant and 79.2% of imipenem-resistance intermediate isolates; no synergy was observed treating imipenem-sensitive isolates. A remarkable decrease in the MIC50 (from 16 to 4 mg/L) and MIC90 (from 64 to 8 mg/L) of imipenem was observed when it was combined with TPEN; the portion of imipenem-resistant isolates also decreased (from 48.4% to 0%). Consistent with these results demonstrating synergy, a time-kill assay showed the addition of TPEN significantly improved the bactericidal activity of imipenem toward M. abscessus. Similarly, EDTA (a potent MBLs inhibitor) promoted the anti-M. abscessus activity of imipenem in a disk assay, corroborating the effect of TPEN and supporting the role of MBLs in imipenem resistance exhibited by some isolates. Conclusion These findings demonstrate that TPEN can reduce the resistance of M. abscessus to imipenem and suggest that the inhibition of MBLs activity is the underlying mechanism.

Abstract
OBJECTIVE To describe women's experience of episiotomy in urban China. DESIGN This is a semistructured, indepth interview with women after episiotomy. We analysed transcriptions using thematic analysis in Chinese. Emerging themes were debated in English to finalise interpretation. SETTING Two community health centres and four hospitals in Shanghai, China. PARTICIPANTS Purposive sampling of 30 postpartum women who had experienced episiotomy; 25 were primiparous and 4 had deliveries by forceps. We interviewed health providers to complement the data. RESULTS We identified four main themes: (1) women's views of the procedure vary considerably; (2) pain interferes with daily life for weeks; (3) long-term anxiety is a consequence for some, described as a 'psychological shadow'; and (4) societal norms assume women will not complain. CONCLUSION Women receive little information in advance about episiotomy, yet the procedure has a wide range of physical and psychological consequences. This includes long-term anxiety about the damage done to them as women.

Abstract
Asymmetric mandibular prognathism is a clinically common skeletal dentomaxillofacial deformity. Unilateral sagittal split ramus osteotomy (USSRO) is an effective alternative procedure to bilateral sagittal split ramus osteotomy (BSSRO) for some patients. However, the biomechanical effect of temporomandibular joint (TMJ) of USSRO has not been fully studied. This study aims to evaluate the stress distribution changes in the TMJ of asymmetric mandibular prognathism treated with BSSRO/USSRO, to validate the clinical feasibility of USSRO. Nineteen patients with mandibular prognathism patients who were treated with BSSRO (n=12) and USSRO (n=7) had preoperative and postoperative computed tomographic scanning. Preoperative and postoperative 3-dimensional finite element analysis (FEA) of functional TMJ movements were made on one BSSRO patient and one USSRO patient. In all patients, the ANB angle and mandibular deviation were significantly improved postoperatively. There was no significant difference in the postoperative ANB angle and mandibular deviation between the BSSRO group and the USSRO group. In two preoperative FEA models, the maximum stresses of non-deviation side TMJ structures were greater than the deviation side during functional movements. The unbalanced stress distribution was corrected postoperatively in both BSSRO/USSRO FE models. Both BSSRO/USSRO can improve the ANB angle and mandibular deviation. The bilateral TMJ structure in patients with asymmetric mandibular prognathism had unbalanced stress, which could be significantly improved with the USSRO as effectively as BSSRO.

Abstract
OBJECTIVE To investigate the association between obstetric haemorrhage and cardiovascular disease up to three decades after pregnancy. DESIGN Population-based cohort study. SETTING AND POPULATION All women who delivered between 1989 and 2016 in Quebec, Canada. METHODS Using hospital admissions data, 1 224 975 women were followed from their first delivery until March 2018. The main exposure measures were antenatal (placenta praevia, placental abruption, peripartum haemorrhage) or postpartum haemorrhage, with or without transfusion. Adjusted Cox regression models were used to assess the association between obstetric haemorrhage and future cardiovascular disease. MAIN OUTCOME MEASURE Cardiovascular hospitalisation. RESULTS Among 104 291 (8.5%) women with haemorrhage, 4612 (4.4%) required transfusion. Women with haemorrhage had a higher incidence of cardiovascular hospitalisation than women without haemorrhage (15.5 versus 14.1 per 10 000 person-years; 2437 versus 28 432 events). Risk of cardiovascular hospitalisation was higher for obstetric haemorrhage, with or without transfusion, compared with no haemorrhage (adjusted hazard ratio [aHR] 1.06, 95% CI 1.02-1.10). Women with haemorrhage and transfusion had a substantially greater risk of cardiovascular hospitalisation (aHR 1.47, 95% CI 1.23-1.76). Among transfused women, placental abruption (aHR 1.79, 95% CI 1.06-3.00) and postpartum haemorrhage (aHR 1.38, 95% CI 1.13-1.68) were both associated with risk of cardiovascular hospitalisation. Antenatal haemorrhage with transfusion was associated with 2.46 times the risk of cardiovascular hospitalisation at 5 years (95% CI 1.59-3.80) and 2.14 times the risk at 10 years (95% CI 1.47-3.12). CONCLUSIONS Obstetric haemorrhage requiring transfusion is associated with maternal cardiovascular disease. The benefit of cardiovascular risk prevention in pregnant women with obstetric haemorrhage requires further investigation. TWEETABLE ABSTRACT Risk of future cardiovascular disease is increased for women with obstetric haemorrhage who require transfusion.

Abstract
AIMS Rg1 is the most active component of traditional Chinese medicine ginseng, having anti-aging and anti-oxidative stress features in multiple organs. Cellular senescence of hepatocytes is involved in the progression of a wide spectrum of chronic liver diseases. In this study, we investigated the potential benefits and mechanism of action of Rg1 on aging-driven chronic liver diseases. MATERIALS AND METHODS A total of 40 male C57BL/6 mice were randomly divided into four groups: control group; Rg1 group; Rg1+d-gal group; and d-gal group. Blood and liver tissue samples were collected for determination of liver function, biochemical and molecular markers, as well as histopathological investigation. KEY FINDINGS Rg1 played an anti-aging role in reversing d-galactose induced increase in senescence-associated SA-β-gal staining and p53, p21 protein in hepatocytes of mice and sustained mitochondria homeostasis. Meanwhile, Rg1 protected livers from d-galactose caused abnormal elevation of ALT and AST in serum, hepatic steatosis, reduction in hepatic glucose production, hydrogenic degeneration, inflammatory phenomena including senescence-associated secretory phenotype (SASP) IL-1β, IL-6, MCP-1 elevation and lymphocyte infiltration. Furthermore, Rg1 suppressed drastic elevation in FOXO1 phosphorylation resulting in maintaining FOXO1 protein level in the liver after d-galactose treatment, followed by FOXO1 targeted antioxidase SOD and CAT significant up-regulation concurrent with marked decrease in lipid peroxidation marker MDA. SIGNIFICANCE Rg1 exerts pharmaceutic effects of maintaining FOXO1 activity in liver, which enhances anti-oxidation potential of Rg1 to ameliorate SASP and to inhibit inflammation, also promotes metabolic homeostasis, and thus protects livers from senescence induced fatty liver disease. The study provides a potential therapeutic strategy for alleviating chronic liver pathology.

Abstract
Macrophages play an important role in the immune system as a key host defense against pathogens. Non-polarized macrophages can differentiate into pro-inflammatory classical pathway-activated macrophages or anti-inflammatory alternative pathway-activated macrophages, both of which play central roles in breast cancer growth and progression in a process called polarization of macrophages. Classical pathway-activated and alternative pathway-activated macrophages can transform into each other and their transformational properties and orientation are determined by cytokines in the tumor microenvironment. Tumor-associated macrophages display many functions, such as tissue reforming, participating in inflammation and tumor growth in breast cancer progression. Some cytokines, such as interleukins and transcriptional activators, reside in the tumor microenvironment and influence tumor-associated macrophages. Chemotherapy is a common treatment for breast cancer and macrophages play an important role in mammary tumor cell migration, cancer invasion, and angiogenesis. This review summarizes the activities of tumor-associated macrophages in the mammary tumor, chemotherapeutic processes and some potential strategies for breast cancer therapy.

Abstract
PURPOSE Capecitabine is a widely used 5-fluorouracil oral prodrug. Hand-foot syndrome (HFS), one of the most common adverse events of capecitabine, impacts patients' quality of life seriously. The pathogenesis of HFS remains unclear but was usually considered as a type of inflammation conducted by cyclooxygenase-2 (COX-2). The COX-2/PGES/EP signaling pathway plays an important role in the inflammatory reaction. We hypothesized that the single nucleotide polymorphisms (SNPs) in this pathway may be associated with the risk of HFS induced by capecitabine. PATIENTS AND METHODS Using DNA from blood samples of 225 patients, we genotyped 19 SNPs in 6 core genes (COX-2, PGES, EP1, EP2, EP3, and EP4). Common Terminology Criteria for Adverse Events version 3.0 was used to grade hand-foot syndrome. We used logistic regression analysis to evaluate the correlations between genotype variants and occurrence of HFS. The cumulative incidence of HFS was assessed by Kaplan-Meier analysis. RESULTS Among the 225 participants, 58.6% (132/225) patients developed into HFS, including 41.3% (93/225) grade 1 HFS, 10.2% (23/225) grade 2 HFS and 7.1% (16/225) grade 3 HFS. Multivariate logistic regression analysis showed the AG/GG genotype of rs3810255 to be associated with a significantly higher risk of grade 2/3 HFS, while the AG/AA genotype of rs17131450 to be associated with a significantly lower risk of grade 2/3 HFS (OR = 3.646, P = 0.011; and OR = 0.266, P = 0.036; respectively). CONCLUSION Our study showed that rs3810255 AG/GG genotypes and rs17131450 GG genotypes to be associated with high risk of capecitabine-induced HFS.

Abstract
Osteoradionecrosis of the mandible (MORN) is one of the most devastating complications caused by radiation therapy in the head and neck region. It is characterized by infection and chronic necrosis of the mandible as the main manifestation. Clinically, MORN-related symptoms include swelling, pain, dysphagia, trismus, masticatory or speech disorders, refractory orocutaneous fistula, bone exposure, and even pathological fracture. MORN has become a challenging clinical problem for oral and maxillofacial surgeons to deal with, but thus far, this problem has not been solved due to the lack of widely accepted treatment algorithms or guidelines. Because of the nonexistence of standardized treatment criteria, most clinical treatment against MORN nowadays is largely based on controversial empirical understandings, while recommendations on post-therapeutic evaluations are scarce. Therefore, to further unify and standardize the diagnosis and treatment of MORN, to decrease the huge waste of medical resources, and ultimately, to improve the wellbeing of the patients, the Chinese Society of Oral and Maxillofacial Surgery (CSOMS) convened an expert panel specialized in MORN from 16 domestic medical colleges and affiliated hospitals to discuss the spectrum of diagnosis and and formulate treatment. In addition, consensus recommendations were also revised with a comprehensive literature review of the previous treatment experiences and research pearls. This 'expert consensus statement on diagnosis and clinical management of MORN' is for clinical reference.

Abstract
Objective: Tracking the information on 1.69 million fetal cases across Guangxi Zhuang Autonomous Region (Guangxi) so as to study the occurrences of total and major birth defects in order to evaluate the ability on related prevention and control programs in Guangxi. Methods: Using the self-developed "Gui Women's System" to establish a database of 1.69 million fetal cases in Guangxi and to analyze the distribution of time, space and population, as well as the outcomes of pregnancy, using the big data. Results: During the 29 months of observation, the overall live birth rate was 99.25%, with stillbirth rate during pregnancy as 0.44%, stillbirth rate during birth as 0.02%, and the 0-6 days mortality rate as 0.14%. The total detection rate on birth defects was 197.63/10 000; the incidence rate was 103.04/10 000, the birth rate was 102.55/10 000. The overall discovery rate of major birth defects was 48.33/10 000, with the incidence rate as 783 000, the birth rate as 0.58/10 000. The discovery rates of major birth defects in 14 cities were between 35 and 68/10 000, and the birth rate dropped significantly to less than 1.00 in 10 000. Nationalities showed that the number of pregnant women with birth defects more than 50 000 would include Hui (9.68/10 000), Yao (9.57/10 000), and Jing (9.37/10 000). With the increasing age of gestation, number of birth defects, incidence of major birth defects also increased. Ninety-five percent of the major birth defects were found within <28 weeks and with the top 5 kinds of major birth defects as complicated congenital heart disease (9.11/10 000), alpha thalassemia (8.36/10 000), and 21-trisomy syndrome (7.85/10 000), beta thalassemia (5.32/10 000) and fetal edema syndrome (4.92/10 000). The top 5 major birth defects appeared as complicated congenital heart disease (9.11/10 000), alpha thalassemia (8.36/10 000), and 21-trisomy syndrome (7.85/10 000), beta thalassemia (5.32/10 000) and fetal edema syndrome (4.92/10 000). Conclusion: Programs leading to increase the rate on discovery of major birth defects were fundamental in effectively reducing the major birth defects.

Abstract
The purpose of this study was to identify potential miRNAs and mRNAs involved in chemotherapy insensitivity in hypopharyngeal squamous cell carcinoma (HSCC) and to explore the underlying mechanisms involved to provide diagnostic markers and therapeutic targets for HSCC. We used microarrays to identify differences in both the mRNA and miRNA expression profiles between a group (twelve patients) sensitive to chemotherapy and a resistant group (nine patients). We then employed bioinformatics tools to examine the functions and pathways involved. The genes and miRNAs most related to chemotherapy sensitivity in HSCC were screened. Finally, a miRNA-mRNA-phenotype network was constructed with an integrated analysis based on the identified miRNAs and mRNAs. Nine differentially expressed miRNAs and one hundred differentially expressed mRNAs were identified, and the functions of these genes and miRNAs were predicted. Bioinformatics analysis revealed a regulatory network consisting of eight genes and two miRNAs that influenced HSCC chemosensitivity. According to our analysis, CCL4L1 may be a potential molecular marker for HSCC chemotherapy, and excess CCL4L1 leads to the upregulation of PRAME and the downregulation of miR-375, thus decreasing HSPB8 expression and promoting chemotherapy sensitivity. Our work provides reliable data for further studies investigating the mechanism of HSCC chemotherapy sensitivity.

Abstract
Blood brain barrier (BBB) disruption plays an important role in brain injury after acute kidney injury (AKI). However, its underlying mechanisms remain poorly understood. Recent evidence has revealed that proper mitochondrial function is essential for BBB permeability. Peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) is a key factor in mitochondrial biogenesis and function. This study was designed to investigate the role of PGC-1α in BBB injury after AKI and its related mechanisms. Mice received recombinant adenovirus encoding murine PGC-1α (100 μl, 1.0 × 109PFU/ml) or vehicle 5 days before renal I/R or sham operation. Twenty-four hours after the operation, brain, kidney and serum samples were collected for assessments. We found that mice suffering from renal I/R injury showed decreased PGC-1α levels in both the kidney and BBB. PGC-1α transfection resulted in increased PGC-1α level and mitochondrial transcripts in BBB at 24 h after AKI. PGC-1α transfection improved renal function, systemic inflammation and BBB permeability via both the paracellular and transcellular pathways. Further study suggested that PGC-1α overexpression elevated fatty acid oxidation related gene expression. Our findings demonstrate the importance of PGC-1α in AKI-induced BBB injury and suggest that it could be a therapeutic target for BBB repair via the regulation of mitochondrial function.

Abstract
BACKGROUND Although massive studies have been conducted to investigate the mechanisms of esophageal squamous cell carcinoma (ESCC) carcinogenesis, the understanding of molecular alterations during the malignant transformation of epithelial dysplasia is still lacking, especially regarding epigenetic changes. RESULTS To better characterize the methylation changes during the malignant transformation of epithelial dysplasia, a whole-genome bisulfite sequencing analysis was performed on a series of tumor, dysplastic, and non-neoplastic epithelial tissue samples from esophageal squamous cell carcinoma (ESCC) patients. Promoter hypermethylation in TGF-β receptor type II (TGFBR2), an important mediator of TGF-β signaling, was identified. Further, we evaluated the methylation and expression of TGFBR2 in tumor samples through The Cancer Genome Atlas multiplatform data as well as immunohistochemistry. Moreover, treatment of ESCC cell lines with5-Aza-2'-deoxycytidine, a DNA methyltransferase inhibitor, reactivated the expression of TGFBR2. The lentiviral mediating the overexpression of TGFBR2 inhibited the proliferation of ESCC cell line by inducing cell cycle G2/M arrest. Furthermore, the overexpression of TGFBR2 inhibited the tumor growth obviously in vivo. CONCLUSIONS The characterization of methylation silencing of TGFBR2 in ESCC will enable us to further explore whether this epigenetic change could be considered as a predictor of malignant transformation in esophageal epithelial dysplasia and whether use of a TGFBR2 agonist may lead to a new therapeutic strategy in patients with ESCC.

Abstract
Mammalian target of rapamycin (mTOR) has two subtypes, i.e., mTORC1 and mTORC2, which contain the Raptor and Rictor core molecules, respectively. The effect of Raptor and Rictor on hypoxia inducible factor (HIF)-1α, HIF-2α, and vascular endothelial growth factor (VEGF) in colorectal cancer (CRC) is unclear. In this work, we investigated the correlations among Raptor, Rictor, HIF-1α, HIF-2α, and VEGF expression in CRC. We subsequently analyzed the clinicopathological features of patients. Immunohistochemistry, western blot, and RT-PCR analyses were performed to detect the expression of Raptor, Rictor, HIF-1α, HIF-2α, and VEGF in 120 cases of CRC and 60 cases of normal colorectal mucosa. CD34 was used to label microvascular density (MVD), which was found to be higher in patients with positive Raptor or Rictor than in those with negative Raptor or Rictor. The positive rates of Raptor, Rictor, HIF-1α, HIF-2α, and VEGF in CRC were significantly higher than in normal colorectal mucosa. Raptor expression was positively correlated with HIF-1α and VEGF but not with HIF-2α expression. By contrast, Rictor expression was positively correlated with HIF-2α and VEGF but not with HIF-1α expression. Survival analysis further indicated that Raptor, Rictor, HIF-1α, HIF-2α, VEGF and lymph node metastasis were independent prognostic factors in CRC. To conclude, Raptor and Rictor expression was related to the initiation and development of CRC and angiogenesis in different ways. The combined detection of Raptor and Rictor is important for patients with colorectal carcinoma in prognosis and optimal therapy.

Abstract
While Asian monsoon (AM) changes have been clearly captured in Chinese speleothem oxygen isotope (δ18O) records, the lack of glacial-interglacial variability in the records remains puzzling. Here, we report speleothem δ18O records from three locations along the trajectory of the Indian summer monsoon (ISM), a major branch of the AM, and characterize AM rainfall over the past 180,000 years. We have found that the records close to the monsoon moisture source show large glacial-interglacial variability, which then decreases landward. These changes likely reflect a stronger oxygen isotope fractionation associated with progressive rainout of AM moisture during glacial periods, possibly due to a larger temperature gradient and suppressed plant transpiration. We term this effect, which counteracts the forcing of glacial boundary conditions, the moisture transport pathway effect.

Abstract
Objective: To evaluate the diagnostic value of thin-slice CT navigation combined with radial endobronchial ultrasound in peripheral lung lesions. Methods: The clinical data of patients with peripheral lung lesions diagnosed by thin-slice CT navigation combined with radial endobronchial ultrasound in National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from November 2015 to August 2018 were retrospectively analyzed. The success rate of thin-slice CT for guiding radial endobronchial ultrasound was statistically analyzed, and the diagnostic rate, sensitivity and specificity of thin-slice CT combined with radial endobronchial ultrasound were analyzed. Results: 140 consecutive patients with 145 lesions were included, 139 lesions in 136 patients were found by thin-layer CT guidance, the success rate was 95.9%; 137 lesions in 135 patients were examined by histology and/or cytology, and 106 lesions were finally diagnosed, the diagnostic rate was 77.37%; and the diagnosis sensitivity and specificity was 88.45% and 99.96%. Histological and cytological diagnostic rate, sensitivity and specificity was 72.18% versus 63.50%, 70.58% versus 66.85%, 100% versus 88.23%, respectively. Factors influencing the diagnostic rate of thin-slice CT navigation combined with radial endobronchial ultrasound include the relationship between the lesion and the target bronchus, the location of the probe and the lesion, and the size of the lesion, and the difference between the farthest generation of bronchoscopy insertion and the bronchial generation of lesions. Five patients had mild bleeding and one ultrasonic probe was damaged. Conclusion: Thin-slice CT has a higher positive rate in guiding peripheral lung lesions with radial ultrasound, and this method has a higher diagnostic value for peripheral lung lesions.

Abstract
Introduction Iron accumulates in the brain during aging, which catalyzes radical formation, causing neuronal impairment, and is thus considered a pathogenic factor in Alzheimer's disease (AD). To scavenge excess iron-catalyzed radicals and thereby protect the brain and decrease the incidence of AD, we synthesized a soluble pro-iron 5-YHEDA peptide. However, the blood-brain barrier (BBB) blocks large drug molecules from entering the brain and thus strongly reduces their therapeutic effects. However, alternative receptor- or transporter-mediated approaches are possible. Methods A low-density lipoprotein receptor (LDLR)-binding segment of Apolipoprotein B-100 was linked to the 5-YHEDA peptide (bs-5-YHEDA) and intracardially injected into senescent (SN) mice that displayed symptoms of cognitive impairment similar to those of people with AD. Results We successfully delivered 5-YHEDA across the BBB into the brains of the SN mice via vascular epithelium LDLR-mediated endocytosis. The data showed that excess brain iron and radical-induced neuronal necrosis were reduced after the bs-5-YHEDA treatment, together with cognitive amelioration in the SN mouse, and that the senescence-associated ferritin and transferrin increase, anemia and inflammation reversed without kidney or liver injury. Discussion bs-5-YHEDA may be a mild and safe iron remover that can cross the BBB and enter the brain to relieve excessive iron- and radical-induced cognitive disorders.

Abstract
Microtia is a congenital malformation of the external ear that can be observed in many species including sheep. However, the genetic basis of microtia still remains unclear. Here, a GWAS was conducted to investigate the genetic basis underlying microtia. A total of 55 samples from 26 microtia and 29 normal animals were genotyped with Illumina OvineHD BeadChip. The strongest significant SNP was identified on OAR6, approximating the evolutionarily conserved region of the HMX1 gene, which is related to congenital malformations of the external ear in other species such as cattle and rats. Sequencing an evolutionarily conserved region surrounding HMX1 revealed a duplication of 76 bp, which is concordant with microtia, suggesting a dominant inheritance mode. Identification of this causal mutation in the HMX1 gene indicates the role of this particular gene in the development of the external ear and provides a genetic marker for selection against microtia.

Abstract
Background Quality by design (QbD) is an advanced drug quality control concept that has been gradually implemented in the optimization of manufacturing processes of Chinese medicines. However, the variation of Chinese medicinal material quality has rarely been considered in published works. Because manufacturing processes may lower the variation introduced through different batches of materials, a material quality control strategy should be developed considering the influences of manufacturing processes. Methods In this work, the processes of extraction, concentration, water precipitation, and chromatography for notoginseng total saponin (NTS) production were investigated while considering Panax notoginseng quality variation as a sample. Ten process parameters were studied simultaneously using a definitive screening design. After the process critical quality attributes (CQAs) were determined, critical process parameters (CPPs) and critical material attributes (CMAs) were identified simultaneously. Then, models utilizing the CMAs, CPPs, and process CQAs were developed. The design space was then calculated using a Monte Carlo simulation method with an acceptable probability of 0.90. A material quality control strategy considering the influences of manufacturing processes was proposed. Results The ginsenoside Rd purity and total saponin purity in the eluate were identified as process CQAs. The ethanol solution concentration used for extraction, the ethanol solution concentration used for elution, and elution time were identified as CPPs. The extractable dry matter content of Panax notoginseng was one of the CMAs. The extractable contents of notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, and ginsenoside Rd were the other CMAs. The inequalities implemented to discriminate the high quality and low quality of Panax notoginseng were developed according to the NTS standard of the Xuesaitong injection. Low quality Panax notoginseng should not be released for NTS production. High quality Panax notoginseng can be treated with feasible manufacturing processing parameters. Verification experiments were carried out successfully for 2 batches of high quality Panax notoginseng. Conclusions In this work, a quality control strategy for herbal materials was developed considering the matching of process characteristics and material quality attributes. This strategy is promising for application to other Chinese medicines.

Abstract
Abstract
Background
ST-elevation myocardial infarction (STEMI) Patients suffered from progressive heart failure, for which progressive and aggravated Left ventricle stiffness was one of the major culprit. Myocardial deformation in the early diastole is largely affected by the left ventricle compliance which could partly reflect chamber stiffness and potentially predict left ventricular remodeling for post-STEMI patients.
Purpose
To determine the value of diastolic strain rate in detecting left ventricle stiffness and early heart failure in post-STEMI patients.
Methods
A number of 52 (M/F: 46/6, age: 54.27 [46.8–62.3]yrs) patients with STEMI three months ago were prospectively recruited from 2016 to 2017. Follow-up was done until 2018. The primary end points were the symptoms of heart failure (NYHA II-IV). Consent was acquired from each patient and 3.0 T MRI was arranged. Imaging analysis was performed on Cvi 42 (V5.9.3 Canada). Peak radial strain (PS) and strain rate (SR) were extracted both from 2D short- and long-axis cine images, while peak circumferential parameters only from the short axis slices and longitudinal the long axis slices. The diastolic strain rate ratios (DSRRs) were calculated as the peak early diastolic SR divided by the peak late diastolic SR, which were derived from the two peak points on the corresponding curve of time-to-SR curve in the diastole (Figure 1a). Receiver-operating characteristics curve analysis and Logistic regression test were done for statistical analysis on R project and P<0.05 was considered as significant.
Results
Three patients were excluded due to unsatisfied cine images. Among the 52 patients, none of the patients died or had congestive heart failure. 23/52 (44.2%) patients complained of heart failure symptoms at the one-year follow-up. No significant difference was found in LVEF and three directional peak strain values or systolic peak strain rates between the patients with and without heart failure. Patients with symptoms had lower Longitudinal PS (P=0.049), early diastolic radial SR (P=0.01798), longitudinal SR (P=0.0042), and decreased DSRR in all directions (Figure 1b). Multivariate Logistic regression test showed that only DSRR in the radial direction on the short axis (DSRR-SR) was the independent predictor of the heart failure symptoms (6.59; range, 6.71–3.68; P=0.026). ROC analysis demonstrated that the DSRR-SR of 2.35 had sensitivity 91.3% and specificity 58.6% for the prediction of heart failure (Figure 1c).
Figure 1
Conclusion
DSRR especially DSRR-SR was more sensitive to left ventricle stiffness change and help predict the progression of heart failure for Post-STEMI patients. Further studies were needed to verify the its association with other cardiovascular clinical events.

Abstract
AIM To investigate whether conicity index, abdominal volume index, body adiposity index, body roundness index, cardiometabolic index and lipid accumulation product compared with waist circumference could predict future diabetes in a 15-year prospective study. METHODS The data were collected in 1992 and recollected in 2007 from the same group of 687 individuals. Anthropometric indices and biochemical data were obtained. Cox's proportional hazards regression models were used to estimate the hazard ratios of anthropometric measures. The discriminatory power of anthropometric measures for incident diabetes were assessed by Harrell's C-statistic. RESULTS During follow-up, 74 participants were newly diagnosed with diabetes. In multivariable Cox regression analysis after adjusting potential for confounders, log10 -conicity index [HR: 1.67 (95% CI: 1.31-2.11) per sd; P < 0.0001], log10 -abdominal volume index [HR: 1.95 (95% CI: 1.50-2.55) per sd; P < 0.0001], log10 -body adiposity index [HR: 1.82 (95% CI: 1.33-2.50) per sd; P < 0.0001], log10 -body roundness index [HR: 2.16 (95% CI: 1.63-2.88) per sd; P < 0.0001], log10 -cardiometabolic index [HR: 1.70 (95% CI: 1.39-2.09) per sd; P < 0.0001], log10 -lipid accumulation product [HR: 2.06 (95% CI: 1.56-2.73) per sd; P < 0.0001] and log10 -waist circumference [HR: 1.99 (95% CI: 1.51-2.46) per sd; P < 0.0001] were significantly associated with incident diabetes. Additionally, lipid accumulation product had the highest Harrell's C-statistic at 0.715 (95% CI: 0.656-0.775), followed by body roundness index at 0.714 (95% CI: 0.658-0.770) and cardiometabolic index at 0.704 (95% CI: 0.643-0.764) then by waist circumference at 0.701 (95% CI: 0.644-0.759). CONCLUSIONS Conicity index, abdominal volume index, body adiposity index, body roundness index, cardiometabolic index and lipid accumulation product were independent predictors of future diabetes. The discriminatory power of body roundness index, cardiometabolic index and lipid accumulation product for diabetes prediction were higher than that of waist circumference.

Abstract
An external electromagnet plus moving PM (permanent magnet) FPCB (flexible printed circuit board) micromirror is proposed in this paper that can overcome two limitations associated with the previous FPCB micromirror with a configuration of an external PM plus moving coil, i.e., (1) it reduces the overall width beyond the mirror plate, and (2) increases the maximum rotation angle. The micromirror has two external electromagnets underneath an FPCB structure (two torsion beams and a middle seat) with two moving PM discs attached to the back and a metal-coated mirror plate bonded to the front of the FPCB middle seat. Modeling and simulation were introduced, and the prototype was fabricated and tested to verify the design. The achieved performance was better than that of the previous design: a maximum resonant rotation angle of 62° (optical) at a driving voltage of ±3 V with a frequency of 191 Hz, the required extra width beyond the mirror plate was 6 mm, and an aperture of 8 mm × 5.5 mm with a roughness of <10 nm and a flatness of >10 m (ROC, radius of curvature). The previous FPCB micromirror's performance was: strain limited maximum rotation angle was 40° (optical), the extra width beyond the mirror plate was 14.7 mm, and had an aperture of 4 mm × 4 mm with a similar roughness and flatness.

Abstract
Aims The present study aims to improve the design of cementless femoral prosthesis stem and achieve better bone ingrowth and long-term stability. Materials and Methods Four models with different directional hollow holes at the proximal end of femoral prosthesis were designed and finite element analysis was applied to calculate the magnitude of conducting force within the differently angled holes and the stress distribution of the femur and prosthesis. Results Holes in prostheses make no difference on the stress values of femoral inner walls. The conducting forces in models trepanned on the lateral plane were 6.60N (0° pore) and 8.40N (45° pore) while forces in models trepanned on the anterior-posterior planes were 0.45N (upper 0° pore), 0.48N (lower 0° pore) and 1.57N (upper 45° pore), 1.51N (lower 45° pore), respectively. Conclusion The position and direction of hollow holes influenced the conducting force in holes but had no influence on stress values of femoral inner walls. Prostheses with one 45° hole trepanned on the lateral plane of proximal prostheses presented best in elevating conducting force.

Abstract
Objective: To evaluate the clinical application of Chinese version of Cornell assessment of pediatric delirium (CAPD) scale in children by a pilot study. Methods: A prospective observational study. From June 2017 to December 2017, the original CAPD screen was translated into Chinese and debugged cross-culturally according to the guidelines, which was further applied in the Department of Critical Care Medicine, Children's Hospital of Chongqing Medical University. The clinical data of 250 patients who were evaluated with the Chinese version of CAPD scale and Richmond agitation-sedation scale were extracted and analyzed with chi-square test or Mann-Whitney U test. Cronbach's α coefficient,Split-half coefficient and intra-group correlation coefficient were used to evaluate the reliability, while exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the structural validity of the scale. The result was compared with the gold standard diagnostic results to evaluate the diagnostic efficacy of the CAPD. Results: Sixty-one (24.4%) patients had delirium during pediatric intensive care unit hospitalization,and significant differences existed between them and 189 patients without delirium in age (χ(2)=11.220, P=0.011), rates of mechanical ventilation (χ(2)=6.691, P=0.010) and length of PICU hospitalization (Z=10.656, P=0.001). The Chinese version of the CAPD scale had high discrimination among the 8 items in the main table without skewed distribution and discrete items. The internal and external reliability of the scale were preferable as the Cronbach's α coefficient was 0.819 and ICC value was 0.835. The KMO value of EFA was 0.834 and Bartlett spherical test showed statistical significance (χ(2)=661.440, P<0.01). CFA constructed a two-factor structural equation model with favorable fit index:Chi-square/degree of freedom (DF) ratio was 1.786 (χ(2)=33.930, P=0.019), goodness of fit index (GFI) was 0.967,adjusted GFI was 0.938,root mean square of the approximate error (RMSEA) was 0.056. A good diagnostic efficacy of this scale was demonstrated by receiver operating characteristic curve analysis as when the cut-off was 10, the area under curve was 0.99 (95%CI: 0.97-0.99), sensitivity was 96.7% (95%CI: 88.7-99.6), specificity was 93.1% (95%CI: 88.5-96.3), positive likelihood ratio was 14.0 (95%CI: 13.2-14.9), and the negative likelihood ratio was 0.035 (95%CI: 0.008-0.200). Conclusion: The Chinese version of the CAPD Scale has favorable reliability,validity,diagnostic efficacy, as well as feasibility, which should be applied in evaluation of pediatric delirium in clinical observation and research in the future.

Abstract
Thin living tissue slices have recently emerged as a new tissue model for cardiac electrophysiological research. Slices can be produced from human cardiac tissue, in addition to small and large mammalian hearts, representing a powerful in vitro model system for preclinical and translational heart research. In the present protocol, we describe a detailed mouse heart transverse slicing and optical imaging methodology. The use of this technology for high-throughput optical imaging allows study of electrophysiology of murine hearts in an organotypic pseudo two-dimensional model. The slices are cut at right angles to the long axis of the heart, permitting robust interrogation of transmembrane potential (Vm) and calcium transients (CaT) throughout the entire heart with exceptional regional precision. This approach enables the use of a series of slices prepared from the ventricles to measure Vm and CaT with high temporal and spatial resolution, allowing (i) comparison of successive slices which form a stack representing the original geometry of the heart; (ii) profiling of transmural and regional gradients in Vm and CaT in the ventricle; (iii) characterization of transmural and regional profiles of action potential and CaT alternans under stress (e.g., high frequency pacing or β-adrenergic stimulation) or pathological conditions (e.g., hypertrophy). Thus, the protocol described here provides a powerful platform for innovative research on electrical and calcium handling heterogeneity within the heart. It can be also combined with optogenetic technology to carry out optical stimulation; aiding studies of cellular Vm and CaT in a cell type specific manner.

Abstract
BACKGROUND AND PURPOSE 3D reconstruction of a targeted area ("safe" triangle and Kambin triangle) may benefit the viability assessment of transforaminal epidural steroid injection, especially at the L5/S1 level. However, manual segmentation of lumbosacral nerves for 3D reconstruction is time-consuming. The aim of this study was to investigate the feasibility of deep learning-based segmentation of lumbosacral nerves on CT and the reconstruction of the safe triangle and Kambin triangle. MATERIALS AND METHODS A total of 50 cases of spinal CT were manually labeled for lumbosacral nerves and bones using Slicer 4.8. The ratio of training/validation/testing was 32:8:10. A 3D U-Net was adopted to build the model SPINECT for automatic segmentations of lumbosacral structures. The Dice score, pixel accuracy, and Intersection over Union were computed to assess the segmentation performance of SPINECT. The areas of Kambin and safe triangles were measured to validate the 3D reconstruction. RESULTS The results revealed successful segmentation of lumbosacral bone and nerve on CT. The average pixel accuracy for bone was 0.940, and for nerve, 0.918. The average Intersection over Union for bone was 0.897 and for nerve, 0.827. The Dice score for bone was 0.945, and for nerve, it was 0.905. There were no significant differences in the quantified Kambin triangle or safe triangle between manually segmented images and automatically segmented images (P > .05). CONCLUSIONS Deep learning-based automatic segmentation of lumbosacral structures (nerves and bone) on routine CT is feasible, and SPINECT-based 3D reconstruction of safe and Kambin triangles is also validated.

Abstract
Dissolved organic nitrogen (DON) has drawn more attention from research into drinking water treatment because of its potential to form nitrogenous disinfection byproducts. Amino acids are important DON constituents that are difficult to remove by conventional water treatment. The permanganate/hydrogen sulfite (PM/BS) system, a novel oxidation process, is used to remove a typical amino acid, glutamate. The factors that affect removal mechanism and the degradation pathways were studied. The results show that the rates of DON and glutamate removal in the PM/BS system within 10 min were 55% and 90%, respectively. The optimum pH for glutamate degradation was 5, and the optimal dosages of KMnO4 and NaHSO3 were 1 mM and 5 mM, respectively. Activation of MnO4- by HSO3- resulted in the oxidation of glutamate at very high rates. As shown by electronic spin resonance (ESR) experiments, Mn (III), SO3-⋅ , and •OH were involved in the degradation process. The oxidation products suggest that most of the glutamate undergoes oxidation to ammonia nitrogen within 10 min, eventually forming N2 in the process. No evidence shows that NO3- and NO2- formed during the entire process. High-performance liquid chromatography-mass spectrometry results reveal that glutamate degradation consists of two separate pathways involving Mn(III), SO3-⋅ , and •OH, both of which convert -NH2 into NH4+ or directly to N2. It can be indicated that nitrogenous disinfection by-products (N-DBPs) formation decreased in the degradation process, as shown by gas chromatograph detection.

Abstract
Objective: To evaluate the short-term outcomes and safety of submucosal tunneling endoscopic resection (STER) for submucosal tumors (SMT) originating from muscularis propria (MP) layer at esophagogastric junction. Methods: The clinical data of 31 patients with SMT originating from MP layer at esophagogastric junction underwent STER were collected and retrospectively analyzed. Results: The success rate of STER of the thirty-one patients was 100%. The mean tumor size was (2.5±1.3) cm and the average operative time was (95.9±56.7) min. Perforation occurred in 3 patients and was successfully clipped by endo-clips during operation. One patient developed delayed bleeding and the bleeding was stopped by endoscopic hemostasis. Twenty-nine leiomyomas and two stromal tumors (GIST) were finally pathologically diagnosed. No local recurrence and distant metastasis were noted during the mean 15.4 months follow-up of 20 cases. According to the lesion size, 31 patients who received STER were divided into two groups. The operation time of maximum diameter ≥3.5 cm group was (134.0±70.6) min, significantly longer than (80.3±42.6) min of maximum diameter <3.5 cm group (P=0.014). However, the en bloc removal rate, postoperative hospital stay and the complication incidence between the two groups had no obvious differences (P>0.05). Univariate analysis showed that the piecemeal removal group had longer tumor diameter, higher incidence of irregular tumor morphology, and longer operative time than the en bloc removal group (all P<0.05). Stepwise logistic regression analysis showed that irregular shape was a risk factor for failure of en bloc removal (OR=18.000, 95% CI: 1.885~171.88, P=0.012). Conclusion: As a new method of minimally invasive treatment, STER technology appears to be a safe and effective option for patients with SMT originating from MP layer at esophagogastric junction.

Abstract
Long noncoding RNAs (lncRNAs), by virtue of their versatility and multilevel gene regulation, have emerged as attractive pharmacological targets for treating heterogeneous and complex malignancies like triple-negative breast cancer (TNBC). Despite multiple studies on lncRNA functions in tumor pathology, systemic targeting of these "undruggable" macromolecules with conventional approaches remains a challenge. Here, we demonstrate effective TNBC therapy by nanoparticle-mediated RNAi of the oncogenic lncRNA DANCR, which is significantly overexpressed in TNBC. Tumor-targeting RGD-PEG-ECO/siDANCR nanoparticles were formulated via self-assembly of multifunctional amino lipid ECO, cyclic RGD peptide-PEG, and siDANCR for systemic delivery. MDA-MB-231 and BT549 cells treated with the therapeutic RGD-PEG-ECO/siDANCR nanoparticles exhibited 80-90% knockdown in the expression of DANCR for up to 7 days, indicating efficient intracellular siRNA delivery and sustained target silencing. The RGD-PEG-ECO/siDANCR nanoparticles mediated excellent in vitro therapeutic efficacy, reflected by significant reduction in the invasion, migration, survival, tumor spheroid formation, and proliferation of the TNBC cell lines. At the molecular level, functional ablation of DANCR dynamically impacted the oncogenic nexus by downregulating PRC2-mediated H3K27-trimethylation and Wnt/EMT signaling, and altering the phosphorylation profiles of several kinases in the TNBC cells. Furthermore, systemic administration of the RGD-PEG-ECO/siDANCR nanoparticles at a dose of 1 mg/kg siRNA in nude mice bearing TNBC xenografts resulted in robust suppression of TNBC progression with no overt toxic side-effects, underscoring the efficacy and safety of the nanoparticle therapy. These results demonstrate that nanoparticle-mediated modulation of onco-lncRNAs and their molecular targets is a promising approach for developing curative therapies for TNBC and other cancers.

Abstract
Abstract
Estrogen receptor α-positive (ER+) breast cancer is routinely treated with therapies targeting the ER axis. However, de novo and acquired resistance to the standard-of-care treatment occur in a significant subset of patients. Multiple mechanisms have been proposed for the resistance, among which genetic alterations to the coding gene of ERα, ESR1, have been extensively studied. Notably, ESR1 hotspot mutations within the ligand binding domain (LBD), novel fusion proteins consisting of the N-terminal domain of ER and the C-terminal domain of a partner gene, and ESR1 gene amplification have been found to be enriched in endocrine-resistant, metastatic breast cancers. Together these ER gene alterations present new challenges in the management of ER+ breast cancer and call for the development of new agents to supplement the current standard-of-care. Around 90% of the ER+ breast cancer cases are also androgen receptor (AR) positive (AR+). Mounting preclinical evidence has demonstrated that AR agonists suppress AR and ER positive (AR/ER+) breast cancer cell growth, in line with clinical activity of androgens. We recently reported the oral selective androgen receptor modulator (SARM) RAD140 is a potent, tissue-selective AR agonist in breast cancer cells which significantly inhibited the growth of AR/ER+ patient-derived xenograft (PDX) models, partly via inhibiting ESR1 gene expression and ER signaling. It also elicited enhanced tumor growth inhibition when combined with a CDK4/6 inhibitor.
Here we further examine the activity of RAD140 in AR/ER+ breast cancer models that are endocrine-independent with a spectrum of ESR1 genetic alterations. In PDX models harboring ESR1 amplification or fusion, RAD140 inhibited tumor growth to a greater degree than fulvestrant, a standard-of-care selective ER degrader (SERD). These results are consistent with the clinical history of the donor patients whose diseases relapsed from or progressed rapidly on fulvestrant. In PDX models with ESR1 Y537S mutation, RAD140 showed anti-tumor activity comparable to that of fulvestrant. Notably, RAD140 treatment also led to substantial reduction of proliferation and colony formation in cell line models recapitulating resistance to the combination of estrogen deprivation and CDK4/6 inhibition.
In summary, RAD140 showed marked anti-tumor activity in AR/ER+, endocrine-resistant breast cancer models with defined genetic background. Importantly, in models with ESR1 amplification and fusion, the AR-targeting RAD140 exhibited more profound inhibitory activity compared with fulvestrant. In models with an ESR1 mutation, the efficacy of RAD140 and fulvestrant was comparable. These results lend support to a clinical hypothesis that AR/ER+, endocrine-resistant tumors with these genetic backgrounds may benefit from AR agonist-based treatment. RAD140 is currently being evaluated in hormone receptor positive (HR+) breast cancer patients (NCT03088527).

Abstract
OBJECTIVES We aimed to explore the association between serum UA and cellular aging markers. DESIGN The current cross-sectional analysis was based on data collected within a type 2 diabetes project. SETTINGS Serum uric acid (UA), which has both antioxidant and pro-oxidant properties, is thought to be involved in cellular aging processes. PARTICIPANTS There are 536 participants included in total, 65.3% of which are women. The average serum UA in women was 267.8 umol/l, lower than in men of 337.7 umol/l (P<0.001). MEASUREMENTS Serum UA, blood lipid profile, HbA1c, plasma glucose and insulin were determined. The peripheral blood leukocyte telomere length (LTL) and mitochondrial DNA copy number (mtDNAcn) were assessed using a real-time PCR assay. Logistic regressions were used to analyze the associations between serum UA and cellular aging markers. RESULTS In Spearman's correlation analysis, there were significantly negative correlations between serum UA and LTL in both women and men (r=-0.162, P=0.006; and r=-0.232, P=0.004, respectively). The logistic regression adjusted for age, BMI, WC, daily energy intake, HbA1c, TG, and LDL-C revealed that the ORs of shorter LTL comparing the extreme serum UA quintiles was 5.52 (95% CI 1.69-18.02; P for trend =0.025) in women and 6.49 (95% CI 1.38-30.45; P for trend =0.108) in men. Furthermore, the OR (95% CI) for shorter LTL per 1 SD increment in serum UA was 1.51(1.10-2.07) in women and 1.64(1.01-2.65) in men. In regard to mtDNAcn, the association between elevated serum UA and lower mtDNAcn only reached significance in men when comparing the second and fifth quintiles with reference quintile (OR=3.73(1.07-13.04) and 3.76(1.01-14.09) , separately, and P for trend=0.066). CONCLUSIONS Our results indicate a significant negative association between serum UA and peripheral blood cellular aging markers. Serum UA might play a role in promoting cellular aging.

Abstract
Objective: To explore the level of resting energy expenditure (REE) estimated by bioelectrical impedance analysis and the association of resting metabolic rate (RMR) with clinical related factors, and provide new ideas for improving protein energy wasting (PEW) in maintenance hemodialysis (MHD) patients. Methods: Seven hundred and sixty-five subjects receiving MHD between July 2015 and September 2016 in 11 hemodialysis centers in Guizhou province were enrolled in this cross-sectional study. Bioelectrical impedance analysis was used to measure RMR and body composition, such as lean body mass, fat mass and body cell mass (BCM). Baseline characteristics, routine blood test indexes and biochemical data of hemodialysis patients were collected. The level of RMR and body composition in hemodialysis patients was compared by gender grouping. Then the patients were divided into four groups according to the cutoff value of RMR quartile. Spearman correlation analysis and multiple linear regression analysis were used to analyze the relationships between RMR and clinical related factors. Results: The average age of MHD patients was (54.96±15.78) years and the duriation of dialysis was (42.3±9.0) months. The level of RMR in male patients (474 cases, 61.96%) was significantly higher than that in female patients [1 591(1 444, 1 764) kcal/d vs 1 226 (1 104, 1 354) kcal/d, P<0.001]. However, this significant difference of RMR between different genders disappeared after adjusting for lean body mass (P=0.193). Multiple linear regression analysis showed that RMR was positively correlated with body surface area (β=0.817) and lactate dehydrogenase (LDH) (β=0.198), and negatively correlated with age (β=-0.141), all P<0.05. Conclusion: RMR levels in patients with maintenance hemodialysis are associated with lactate dehydrogenase level, which may become a new index to evaluate energy consumption.

Abstract
Objective:The aim of this study is to explore the role of cineMRI in the localization of upper airway obstruction in complicated pediatric OSAS. Method:Eleven persistent OSAS and 11 complex OSAS patients underwent cineMRI. Each patient was imaged midline sagittal and axial magnetic resonance cine image. The obtained sagittal and axial images were displayed in cine format, creating a real time "movie" of airway motion, to make a personalized treatment for each child. Polysomnography was performed to evaluate the effectiveness of cineMRI directed treatment for pediatric OSAS. Result:cineMRI could effectively define the upper airway obstruction level. There was a significant improvement in AHI (P=0.019) and saturation nadir (P<0.01). Conclusion:cineMRI is an effective method for assessing the level of airway obstruction on persistent or complex pediatric OSAS.

Abstract
BACKGROUND AND PURPOSE Some retrospective studies have found that the aneurysm wall enhancement on high-resolution MR vessel wall postgadolinium T1WI has the potential to distinguish unstable aneurysms. This study aimed to identify hemodynamic characteristics that differ between the enhanced and nonenhanced areas of the aneurysm wall on high-resolution MR vessel wall postgadolinium T1WI. MATERIALS AND METHODS TOF-MRA and high-resolution MR vessel wall T1WI of 25 patients were fused to localize the enhanced area of the aneurysm wall. Using computational fluid dynamics, we studied the aneurysm models. Mean static pressure, mean wall shear stress, and oscillatory shear index were compared between the enhanced and nonenhanced areas. RESULTS The aneurysmal enhanced area had lower wall shear stress (P < .05) and a lower oscillatory shear index (P = .021) than the nonenhanced area. In addition, the whole aneurysm had lower wall shear stress (P < .05) and a higher oscillatory shear index (P = .007) than the parent artery. CONCLUSIONS This study suggests that there are hemodynamic differences between the enhanced and nonenhanced areas of the aneurysm wall on high-resolution MR vessel wall postgadolinium T1WI.

Abstract
Objective:To investigate the imaging characteristics of bony erosion, fungal culture and related factors in allergic fungal rhinosinusitis (AFRS). Method:Sixty cases of AFRS were reviewed in this study. The characteristics of Computed Tomography and Magnetic Resonance Imaging including positive rate of bony erosion, eroded sites, disease extension and sinus expansion were summarized. Fungal culture and identification of nasal secretion were done. The correlation between the degree of sinus expansion, species of fungi and bony erosion was evaluated by statistical analysis. Result:Of the 60 patients, 18 (30%) had bony erosion. There was a significant difference in the proportion of bone erosion among the sinuses (P<0.05). The most commonly eroded site was the ethmoid sinus. The orbit were the most common adjacent anatomic spaces to exhibit disease extension, and anterior cranial fossa is the second most common. Statistical analysis revealed a significant association(P<0.05)of bone erosion with sinus expansion. The positive rate of fungal culture was 51.3%, among which the most common is Aspergillus. Statistical analysis shows no association(P>0.05)of bone erosion with specific fungi. Conclusion:Bone erosion is an important imaging feature of AFRS. Bone erosion may cause by sinus expansion. Extension of disease into the orbit or intracranial cavity results from a natural progression of disease after erosion occurs. Specific fungal species that can cause bone erosion was found.

Abstract
Objective: To investigate the epidemiological characteristics of hospitalized pediatric patients with burns and explore the prevention and treatment strategy of pediatric burns. Methods: Medical records of pediatric burn patients hospitalized in multiple departments of Children's Hospital of Chongqing Medical University from January 2012 to December 2016 were retrospectively analyzed. Data including gender, age, residence, ways of paying, total burn area, burn severity, cause, time, and place of burns, prehospital treatment ways, clinical outcome, length of hospital stay were collected and processed with chi-square test, Kruskal-Wallis H test, and Bonferroni correction. The factors which influence wound healing were processed with multivariate logistic regression analysis. Results: (1) A total of 1 946 pediatric burn patients with complete medical records were hospitalized in Children's Hospital of Chongqing Medical University during the 5 years, with 1 127 boys (57.91%), which were more than 819 girls (42.09%). Pediatric patients≤3 years old were with the highest incidence of burns of 87.15% (1 696/1 946). There was no significantly statistical difference in gender composition ratio among pediatric patients of different ages (χ2=2.294, P= 0.318). (2) The residence of 1 536 pediatric patients (78.93%) were in town, and most of them used urban resident essential medical insurance for medical cost. Most of the pediatric patients living in rural areas paid the medical cost at their own expense. There was significantly statistical difference in way of paying between pediatric patients living in urban and those in rural areas (χ2=658.324, P<0.05). (3) The pediatric patients with total burn surface area≥5% total body surface area (TBSA) and<15% TBSA were the most (1 200 cases, accounting for 61.66%). The pediatric patients with moderate burns were the most (1 225 cases, accounting for 62.95%), followed by mild burns (494 cases, accounting for 25.39%), severe burns (124 cases, accounting for 6.37%), and extremely severe burns (46 cases, accounting for 2.36%). (4) The pediatric patients with scald caused by hot water were the most (1 801 cases, accounting for 92.55%), followed by flame burns (69 cases, accounting for 3.55%), chemical burns (44 cases, accounting for 2.26%), and electrical burns (32 cases, accounting for 1.64%). There was significantly statistical difference in cause of injury among pediatric patients of different ages (χ2=85.471, P<0.05). (5) The incidence of burns of pediatric patients in Spring was 27.95% (544/1 946), which was slightly higher than those in other seasons. There was significantly statistical difference in the burn season among pediatric patients admitted to the hospital in different years (χ2= 23.172, P< 0.05). As to burn place, most of burns of pediatric patients happened at home (1 776 cases, accounting for 91.26%). (6) There was significantly statistical difference in clinical outcome among pediatric patients with different prehospital treatments (H=16.005, P<0.05). There was significantly statistical difference in clinical outcome between pediatric patients with reasonable prehospital treatments and those with unreasonable prehospital treatments (H=-64.990, P<0.05), and between pediatric patients with reasonable prehospital treatments and those without any treatment (H=-74.775, P<0.05). There was no significantly statistical difference in clinical outcome between pediatric patients with unreasonable prehospital treatments and those without any prehospital treatment (H=-9.785, P>0.05). (7) The median of length of hospital stay of pediatric patients was 8 days. The pediatric patients with length of hospital stay≤7 days were the most (834 cases, accounting for 42.86%), and the pediatric patients with length of hospital stay>30 days were the least (39 cases, accounting for 2.00%). (8) The way of prehospital treatment and cause of injury were independent risk factors influencing wound healing (χ2=7.946, 12.977, P<0.05). With no prehospital treatment as benchmark, reasonable prehospital treatments promoted wound healing (odds ratio=1.662, 95% confidence interval=1.129-2.447, P<0.05). With chemical burns as benchmark, electrical burn wounds were harder to heal (odds ratio=0.144, 95% confidence interval=0.028-0.734, P<0.05). Conclusions: Pediatric burn patients hospitalized in Children's Hospital of Chongqing Medical University were mainly boys≤3 years old with moderate scald caused by hot water at home in urban areas. Timely and reasonable prehospital treatments are beneficial to wound healing.
