Abstract
BACKGROUND Infection is a serious potential consequence of surgery to complete a spontaneous abortion. Antibiotic prophylaxis before some operations has been shown to reduce the risk of postoperative infections. However, for miscarriage surgery, evidence is lacking to show effectiveness. METHODS In this systematic review, the electronic databases of Cochrane Central Register of Controlled Trials, EMBASE, and PUBMED will be searched from inception to May 1, 2020. Randomized controlled trials that assessed the effectiveness and safety of antibiotic prophylaxis for preventing infection for patients undergoing miscarriage surgery will be included. All process of the study selection, data extraction, and methodology evaluation will be carried out by two authors independently. RevMan 5.3 software will be utilized for statistical analysis. RESULTS This study will provide a detailed summary of latest evidence related to the effectiveness and safety of antibiotic prophylaxis for preventing infection for patients undergoing miscarriage surgery. CONCLUSION The findings of this study may provide possible guidance for the use of antibiotic prophylaxis for preventing infection for patients undergoing miscarriage surgery. DISSEMINATION AND ETHICS Ethical approval is not required in this study, because it will not collect the original data from individual patient. The results are expected to publish through a peer-reviewed journal. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD CRD42020155643.

Abstract
Objective: To explore the clinical application effects of portable visual retractor in superficial temporal fascia flap harvesting. Methods: From January 2010 to June 2019, 27 patients meeting the inclusion criteria and planning to perform operation of superficial temporal fascia flap harvesting were admitted to the Department of Plastic and Reconstructive Surgery of the First Clinical Medical Center of the People's Liberation Army General Hospital. The patients were divided into traditional surgical method group [6 males and 3 females, aged (34±14) years], cold light source retractor group [6 males and 4 females, aged (35±16) years], and portable visual retractor group [7 males and 1 female, aged (30±14) years] according to way of superficial temporal fascia flap harvesting. The superficial temporal fascia flaps of patients in traditional surgical method group were resected by traditional way of resection, and the superficial temporal fascia flaps of patients in cold light source retractor group and portable visual retractor group were resected at assistance of cold light source retractor and portable visual retractor, respectively. Length of incision, operation time, intraoperative blood loss volume, postoperative drainage volume, and postoperative complication of patients in 3 groups were observed and recorded. Data were processed with Fisher's exact probability test, one-way analysis of variance, least significant difference test, Kruskal-Wallis H test, and Bonferroni correction. Results: The length of incision of patients in visual retractor group was (3.6±0.8) cm, significantly shorter than (12.6±1.6) cm in traditional surgical method group and (5.8±0.9) cm in cold light source retractor group (P<0.05). The incision length of patients in traditional surgical method group was significantly longer than that in cold light source retractor group (P<0.05). The operation time of patients in visual retractor group was 24.0 (23.3, 25.8) min, significantly shorter than 35.0 (30.5, 36.5) min in traditional surgical method group and 28.5 (26.8, 30.5) min in cold light source retractor group (H=16.5, 9.8, P<0.05). The operation time of patients in traditional surgical method group was significantly longer than that in cold light source retractor group (H=6.6, P<0.05). The intraoperative blood loss volume was (26±3) mL of patients in visual retractor group, significantly less than (34±4) mL in traditional surgical method group and (30±6) mL in cold light source retractor group (P<0.05). The intraoperative blood loss volume of patients in traditional surgical method group was significantly more than that in cold light source retractor group (P<0.05). The postoperative drainage volumes of patients in visual retractor group, cold light source retractor group, and traditional surgical method group were (33±4), (34±6), and (31±7) mL, respectively, and there were no significantly statistical differences in postoperative drainage volumes among patients in the three groups (F=0.3, P>0.05). There were no severe complications such as ischemia and necrosis of superficial temporal fascia flaps in patients of the three groups. One patient in cold light source retractor group had subcutaneous hematoma after operation, which was improved by removing stitches and hematoma. Conclusions: Superficial temporal fascia flap harvesting at the assistance of portable visual retractor has the advantages of clear visual field, simple operation, short operation time, small incision, and less intraoperative blood loss.

Abstract
In order to study the effects of chitinase-like protein YKL-40 on proliferation, apoptosis, and migration of human bronchial epithelial cell line (BEAS-2B), and the underlying mechanisms, we cultured BEAS-2B alone or with different concentrations of YKL-40. thiazolyl blue tetrazolium bromide (MTT) assay was used to examine the cell proliferation. Annexin V-fluorescein isothiocyanate isomer (FITC)/propidium iodide staining and scratch assay were performed to test the cell apoptosis and migration. The concentrations of transforming growth factor-β1 (TGF-β1), Smad3, Smad7, alpha-smooth muscle actin (α-SMA), interleukin-4 (IL-4), IL-6, and IL-8 in the cell culture supernatant were detected by enzyme-linked immunosorbent assay. The messenger RNA and protein levels of YKL-40, TGF-β1, Smad3, Smad7, and α-SMA were detected by reverse transcription polymerase chain reaction and Western blot. BEAS-2B cells cultured with different concentrations of YKL-40 showed significantly higher cell proliferation and migration and inflammatory cytokines compared with that of control group, while the cell apoptosis was significantly lower than that of control group (p < 0.05). In addition, BEAS-2B cells cultured with YKL-40 had increased TGF-β1, Smad3, Smad7, and α-SMA levels in the supernatant, compared with that of BEAS-2B cells cultured alone (p < 0.05). Furthermore, LY364947, as TGF-β1/Smads signaling pathway inhibitor, decreased cell proliferation and migration ability and enhanced cell apoptosis of BEAS-2B cells compared with control group (p < 0.05). However, YKL-40 administration reversed the effect of LY364947 on the biological behavior of BEAS-2B cells. YKL-40 could affect the biological behaviors of BEAS-2B cells, which might be related to the TGF-β1/Smads pathway.

Abstract
Objective: To understand the basic information of anti-mitochondrial antibody (anti-AMA)-positive patients after initial diagnosis, and to set groundwork for further exploring the clinical significance of AMA in various diseases. Methods: Demographic data and related clinical information recorded through the Information System of Peking University People's Hospital from January 2013 to December 2016 were collected. Patients whose AMA and/or AMA-M2 first- tested as positive were recorded. Complications were classified according to the International Classification of Diseases. Results: A total of 1323 AMA positive cases were discovered for the first time. Among them, 78.0% were women, and the age of initial diagnosis was 56.8 ± 16.0 years. The first three initially diagnosed departments were rheumatology and immunology (37.4%), liver Disease (15.9%) and hematology (15.9%) relevant to musculoskeletal and connective tissue diseases (45.2%), hematology and hematopoietic organs and immune diseases (30.6%) and circulatory system diseases (29.7%). There were 297 newly confirmed cases of primary biliary cholangitis (PBC); accounting for 89.2% of women, and the age of initial diagnosis was 60.1 ± 12.4 years. The top three departments of initially diagnosed as PBC were liver disease (37.7%), rheumatology (33.0%) and gastroenterology (15.2%), of which 39.7% had musculoskeletal and connective tissue diseases, 27.9% had circulatory diseases, and 24.9 % were combined with endocrine and metabolic diseases. Conclusion: Besides PBC and other autoimmune diseases, AMA and / or AMA-M2 positivity can be observed in a variety of diseases in several clinical departments, and its clinical significance remains to be further clarified.

Abstract
We report on an emerging symmetry axis in the magnetoresistance of bulk single crystals of quasi-one-dimensional Li0.9Mo6O17 below T min = 25 K, the temperature at which the electrical resistivity experiences a minimum. Detailed angle-dependent magnetoresistance sweeps reveal that this symmetry axis is induced by the development of a negative magnetoresistance, which is suppressed only for magnetic fields oriented along the poles of the MoO6 octahedra that form the conducting chains. We show that this unusual negative magnetoresistance is consistent with the melting of dark excitons, composed of previously omitted orbitals within the t 2g manifold that order below T min. The unveiled symmetry axis in directional magnetic fields not only provides evidence for the crystallization of these dark excitons but also sheds new light on the long-standing mystery of the metal-insulator transition in Li0.9Mo6O17.

Abstract
Aims and background This report retrospectively analyzes 9 cases of epithelial ovarian cancer with persistent retroperitoneal metastasis after intraperitoneal surgery (without systematic lymphadenectomy) and chemotherapy. Methods All 9 patients were diagnosed as FIGO stage I to IV at the time of primary surgery. They received combined postoperative chemotherapy (8 cases with a cisplatin-based regimen and 1 with adriamycin and endoxan). They were submitted to pelvic and paraaortic lymphadenectomy at the National Cancer Institute of Milan during the period 1990-1994. Results All patients presented no evidence of disease in the abdominal cavity but retroperitoneal metastasis, which was the unique metastatic site. Chemotherapy was administered as adjuvant therapy after lymphadenectomy. Six patients were free of disease for 14 to 61 months. One patient with vaginal recurrence at the 18th month was treated with radiotherapy and chemotherapy, but died of widespread disease 25 months after lymphadenectomy. Two patients with massive positive lymph nodes died of brain and lung metastasis 20 and 6 months later, respectively. Conclusions We conclude that retroperitoneal metastasis may be the only site of persistent disease and that systematic lymphadenectomy technically feasible in this situation to increase the opportunity for local disease control and to obtain a good result.

Abstract
Due to its cooperative nature, magnetic ordering involves a complex interplay between spin, charge, and lattice degrees of freedom, which can lead to strong competition between magnetic states. Binary Fe3Ga4 is one such material that exhibits competing orders having a ferromagnetic (FM) ground state, an antiferromagnetic (AFM) behavior at intermediate temperatures, and a conspicuous re-entrance of the FM state at high temperature. Through a combination of neutron diffraction experiments and simulations, we have discovered that the AFM state is an incommensurate spin-density wave (ISDW) ordering generated by nesting in the spin polarized Fermi surface. These two magnetic states, FM and ISDW, are seldom observed in the same material without application of a polarizing magnetic field. To date, this unusual mechanism has never been observed and its elemental origins could have far reaching implications in many other magnetic systems that contain strong competition between these types of magnetic order. Furthermore, the competition between magnetic states results in a susceptibility to external perturbations allowing the magnetic transitions in Fe3Ga4 to be controlled via temperature, magnetic field, disorder, and pressure. Thus, Fe3Ga4 has potential for application in novel magnetic memory devices, such as the magnetic components of tunneling magnetoresistance spintronics devices.

Abstract
BACKGROUND Plasminogen activator inhibitor-1 (PAI-1) is the primary inhibitor of the endogenous fibrinolytic system and is known to be increased in obesity, insulin resistance and non-alcoholic fatty liver disease (NAFLD). We previously demonstrated that PAI-1 levels were closely related to the amount of hepatic steatosis in children. OBJECTIVES The aim of this study was to characterize plasma PAI-1 in relationship to severity of inflammation and fibrosis, as well as to plasma lipids in children with NAFLD. METHODS In 44 children with NAFLD, plasma PAI-1 levels and lipids were measured at the time of a liver biopsy. Hepatic histological features were systematically scored. Trend analysis was applied to determine the correlation of plasma PAI-1 levels with lipid markers for cardiovascular disease and with the staging of histological features in the liver. RESULTS We found that plasma PAI-1 levels were significantly increased in children with increased severity of steatosis, lobular inflammation, ballooning and fibrosis. Furthermore, PAI-1 was strongly correlated with plasma lipids and insulin resistance indices. CONCLUSIONS PAI-1 appears to be tightly related to both histologic severity of NAFLD as well as systemic features of the disease including insulin resistance and dyslipidemia. PAI-1 may be a mediator of disease progression and future cardiovascular complications in children with NAFLD.

Abstract
There is an increasing need to understand long-term metabolic changes and resultant comorbidities because life expectancy is increasing after pediatric kidney and liver transplants. We evaluated differences in classic and novel cardiometabolic biomarkers among obese and normal weight adolescent transplant recipients. We enrolled a total of 80 adolescent (mean±SD, 14.8 years ±3.0) transplant recipients (63 kidney, 17 liver) with mean duration from transplantation of 6.0 (±4.1) years. Among kidney transplant recipients, overweight and obese individuals had higher leptin (16.7 vs 7.5 μg/mL, P<.001), lower HDL (1.1 vs 1.3 mmol/L, P=.02), higher free fatty acid (0.6 vs 0.5 mmol/L, P=.03), higher apoB-to-apoA1 ratio (0.8 vs 0.6, P=.03), and higher glucose (5.8 vs 4.3 mmol/L, P=.03) concentrations compared to normal weight individuals. Regardless of obesity status, over half of all participants (57.5%) were considered at high cardiometabolic risk using consensus guidelines, and this was more pronounced for kidney transplant recipients (61.9%). Post-transplantation adolescents have increased cardiometabolic risk characterized by traditional risk factors of obesity and diabetes. The presence of obesity significantly worsens biomarkers of cardiometabolic risk. Future studies should explore whether treatment of obesity can improve the health and long-term outcomes for children undergoing solid organ transplant.

Abstract
Objective: To investigate the contents and features of drug-induced liver injury (DILI) database called LiverTox, as well as 37 herbal preparations included in this database. Methods: Firstly, the source and contents of LiverTox were briefly introduced, including the clinical features, types, severity, and causality assessment scale of DILI. Secondly, detailed information of 37 herbal preparations included in the class of "Herbals and Dietary Supplements" were extracted, including drug name, origin, efficacy, constituents, type of liver injury, and manifestations, to perform a preliminary statistical analysis. Finally, a comparative analysis was performed between such information and current knowledge of Chinese herbal medicine-induced liver injury in China. Results: LiverTox was a DILI database with open access and rich information and provided practical information on treatment, typing, causality assessment, and treatment. Among the 37 herbal preparations, 28 had the risk of liver injury. The most common indication was weight loss, followed by arthritis and constipation. The latency of hepatotoxicity ranged from 4 weeks to 6 months. Compared with the current knowledge in China, there were differences in the varieties and indications for herbal preparations with hepatotoxicity included in LiverTox, and many herbals with acknowledged hepatotoxicity in China were not included. Conclusion: LiverTox database is concise and practical, but there are certain differences between the herbal preparations included in this database and current knowledge in China.

Abstract
CONTEXT Triterpenes from Poria cocos Wolf (Polyporaceae) have been used to treat various diseases in traditional Chinese medicine. However, the antiepileptic effects and mechanism are not fully understood. OBJECTIVE The objective of this study is to investigate the antiepileptic properties of total triterpenes (TTP) from the whole P. cocos. MATERIALS AND METHODS The ethanol extract TTP was identified by HPLC fingerprint analysis. Male ICR mice were gavaged (i.g.) with TTP (5, 20, 80 or 160 mg/kg) or reference drugs twice a day for 7 d. Antiepileptic activities of TTP were evaluated by maximal electroshock (MES)- and pentylenetetrazole (PTZ)-induced seizures in mice for 30 and 60 min, respectively. Locomotor activity and Rota-rod tests were performed for 60 min and 5 min, respectively. The levels of glutamic acid (Glu), aspartic acid (Asp), γ-aminobutyric acid (GABA) and glycine (Gly) in convulsive mice were estimated. The chronic epileptic model of Wistar rats was built to measure expressions of glutamate decarboxylase 65 (GAD65) and GABAA in rat brain after TTP treatment. RESULTS The LC50 of TTP (i.g.) was above 6 g/kg. TTP (5-160 mg/kg) protected mice against MES- and PTZ-induced convulsions at 65.0% and 62.5%, respectively, but have no effect on rota-rod treadmill; TTP (20-160 mg/kg) significantly reduced the locomotor activities, shortened the onset of pentobarbital sodium-induced sleep; TTP decreased Glu and Asp levels in convulsive mice, but increased the GAD65 and GABAA expressions in chronic epileptic rats at doses usage. DISCUSSION AND CONCLUSION TTP extracted from P. cocos possessed potential antiepileptic properties and is a candidate for further antiepileptic drug development.

Abstract
OBJECTIVE To explore the correlation of urinary cysteinyl leukotriene E4 (CysLTE4) and diagnosis of bronchopulmonary dysplasia (BPD) in premature infants. METHOD One hundred and fifty-eight newborn infants were consecutively admitted to the neonatal intensive care units of First Affiliated Hospital of Nanjing Medical University from November 2014 to October 2015.The infants were divided into 3 groups according to the diagnosis on discharge.Sixty-one term infants were classified as having no pulmonary diseases, 52 premature infants were classified as without BPD, and 45 premature infants with BPD were diagnosed at 28 d after birth.Urinary CysLTE4 levels of newborns within 3 days after birth were measured in a blinded way by enzyme- linked immunosorbent assay and were compared among 3 groups, and were evaluated for the diagnostic value and the correlation of gestational age and birth weight.Statistical analysis was performed using correlation analysis, one-way analysis of variance and χ(2) test etc. RESULT In infants with BPD, the mean urinary CysLTE4 level was (191.0±29.3) ng/L which significantly higher than the premature group without BPD ((164.1±22.7) ng/L) and term infant group ((151.6±41.9) ng/L, F=18.70, P<0.05). Urinary CysLTE4 level within 3 days of life in newborn inversely correlated with gestational age and birth weight (Pearson=-0.33, -0.38, P<0.01). The area under the curve was 0.78, 95%CI: 0.70-0.86, P<0.01, when cutoff was 187.7 ng/L, with Youden index 0.59, sensitivity 77.8% and specificity 81.4%, respectively. CONCLUSION Urinary CysLTE4 level is up-regulated in BPD infants within early days of life which may be a useful biomarker of early diagnoses of BPD.

Abstract
BACKGROUND Damage to melanocytes induced by oxidative stress plays an important role in the pathogenesis of vitiligo. A polyphenol found in green tea, (-)-epigallocatechin-3-gallate (EGCG), exhibits certain antioxidative effects in the treatment of various diseases. The major problem that limits the clinical application of this polyphenol is its low bioavailability and stability. Peracetylated EGCG (AcEGCG), a fully acetylated derivative of EGCG, is more stable and bioavailable than EGCG, but the effects of its action on human epidermal melanocytes have not been elucidated. AIM To compare the protective effects of AcEGCG and EGCG on hydrogen peroxide (H2 O2 )-induced damage to human melanocytes. METHODS Effects of AcEGCG and EGCG on human melanocytes were examined by measuring cell viability, levels of reactive oxygen species (ROS), the mitochondrial membrane potential (ΔΨm)and protein levels of caspase-9, caspase-3 and p38 mitogen-activated protein kinase. RESULTS Both AcEGCG and EGCG decreased ROS generation, restored lost mitochondrial membrane potential and reduced H2 O2 -induced apoptosis in melanocytes. All of these effects were more pronounced with AcEGCG than with EGCG. Furthermore, AcEGCG effectively suppressed H2 O2 -induced p38 mitogen-activated protein kinase phosphorylation, which has been suggested to contribute to melanocyte damage. CONCLUSIONS AcEGCG is a more potent agent than EGCG for protection of melanocytes from oxidative damage.

Abstract
Brain natriuretic peptide (BNP) is used as a marker of cardiac dysfunction to predict heart failure mortality. The significance of the prognostic ability of BNP for liver cirrhosis remains unknown, although the levels of BNP seen in cirrhosis are high. We aimed to determine whether the BNP level is related to the stage of cirrhosis and could serve as a prognostic marker of cirrhosis (predict the 1-year all-cause mortality). We recruited 92 patients at different stages of cirrhosis and 81 controls matched by age and gender for this study. At admission, cardiac physical examination and BNP measurements were performed. Upon discharge, the 89 patients were followed up for 12 months. The median BNP levels of patients with cirrhosis were 167.0 pg/mL, which were significantly higher than those of the control group (167.0 vs 34.8 pg/mL, P = 0.001). Serum BNP levels were positively correlated with the Child score, the grade of esophageal varices, a history of spontaneous bacterial peritonitis, and the presence of ascites and collateral circulation. BNP levels above the median were associated with an increased occurrence of death within 12 months of discharge (log rank P = 0.025), as determined by univariate and multivariate Cox regression analyses. Esophageal varices, large/medium volume ascites, and BNP levels were related to the clinical outcome (P = 0.034, 0.030, and 0.025, respectively). Together, these results suggested that serum BNP levels are significantly correlated with the stage of cirrhosis, suggesting that BNP levels might serve as a significant predictor for 1-year all-cause mortality.

Abstract
Novel aromatic poly(benzoxazole–imide)s containing naphthalene were prepared from synthesized 1,4-di(5-aminobenzoxazol-2-yl)naphthalene and commercial dianhydrides by conventional two-step polymerization. The polymers showed high levels of tensile strength of up to 294 MPa and modulus of up to 6.5 GPa. The glass transition temperatures of the polymers were observed between 267°C and 345°C. The 5% weight loss temperatures of the polymers were tested in the range of 517–562°C in nitrogen atmosphere. The excellent properties of polymers were attributed to their rigid-rod-like molecular structure. The polymers emitted different fluorescence with maximum emission wavelengths in the range of 470–560 nm. Increasing the dianhydride electron affinity, the emission spectra peak value of polyimides (PIs) except PI6 increased gradually, but the fluorescent intensity of the PIs decreased. The 1,4-bis(3,4-dicarboxyphenoxy)benzene dianhydride-derived PI film exhibit highly fluorescent characteristics; however, the PI film from pyromellitic dianhydride was nonfluorescent.

Abstract
BACKGROUND To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. METHOD Data were from the World Health Organization (WHO) World Mental Health (WMH) surveys. Representative household samples were interviewed face to face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n = 63,678) and analyzed at different levels of clinical severity. RESULTS Among those with a DSM-IV disorder in the past 12 months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. A desire to handle the problem on one's own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers to both initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment drop-out (39.3%), followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). CONCLUSIONS Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide.

Abstract
BACKGROUND AND PURPOSE Differentiation of glioblastomas and solitary brain metastases is an important clinical problem because the treatment strategy can differ significantly. The purpose of this study was to investigate the potential added value of DTI metrics in differentiating glioblastomas from brain metastases. MATERIALS AND METHODS One hundred twenty-eight patients with glioblastomas and 93 with brain metastases were retrospectively identified. Fractional anisotropy and mean diffusivity values were measured from the enhancing and peritumoral regions of the tumor. Two experienced neuroradiologists independently rated all cases by using conventional MR imaging and DTI. The diagnostic performances of the 2 raters and a DTI-based model were assessed individually and combined. RESULTS The fractional anisotropy values from the enhancing region of glioblastomas were significantly higher than those of brain metastases (P < .01). There was no difference in mean diffusivity between the 2 tumor types. A classification model based on fractional anisotropy and mean diffusivity from the enhancing regions differentiated glioblastomas from brain metastases with an area under the receiver operating characteristic curve of 0.86, close to those obtained by 2 neuroradiologists using routine clinical images and DTI parameter maps (area under the curve = 0.90 and 0.85). The areas under the curve of the 2 radiologists were further improved to 0.96 and 0.93 by the addition of the DTI classification model. CONCLUSIONS Classification models based on fractional anisotropy and mean diffusivity from the enhancing regions of the tumor can improve diagnostic performance in differentiating glioblastomas from brain metastases.
