Abstract
BackgroundChildhood trauma is known to predispose to a variety of psychiatric disorders, including anxiety, mood, and substance use. However, the relationship between childhood trauma and obsessive-compulsive disorder (OCD) has not been well studied. The aim of the present study is to compare childhood trauma experience between OCD and controls, and explore its impact on symptoms of OCD.MethodsOne hundred eighty-five outpatients who met DSM-IV diagnosis of OCD and 132 gender- age- matched controls were included in this study. The Early Trauma Inventory Self Report-Short Form (ETISR-SF) was administered to all participants to evaluate 4 types (general, physical, emotional and sexual) of trauma and its severity. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to measure the severity of symptoms of OCD patients.ResultsOCD patients showed a significantly greater severity in all four types of trauma when compare with controls. 77% of OCD patients reported at least one type of childhood trauma experience, and 18% reported sexual trauma. Sexual trauma experience is significantly associated with obsessive but not compulsive symptoms of OCD patients. When compared to female OCD patients, male patients reported significantly higher scores on general trauma, physical abuse and emotional abuse; but lower of sexual abuse.ConclusionThe present study revealed the high prevalence of childhood trauma among OCD patients, which is consistent with evidence from previous studies suggesting that childhood trauma may play a role in the development of mental disorders. It may be important to consider the impact of childhood trauma in OCD clinical management.

Abstract
Aspergillus spp. are a common contaminant of grapes and a major source of mycotoxins. China is the largest producer of grape in the world now, however, the toxigenic Aspergillus population on grape in this country is still largely unknown. In this study, a total of 345 strains were isolated from grapes of 13 main grapevine producing regions in China. Based on calmodulin gene sequences, eight species within Aspergillus section Nigri were identified. Among them, Aspergillus tubingensis (48.7%) was predominant, followed by Aspergillus welwitschiae (20.6%) and Aspergillus aculeatinus (11%). Average of contamination level was up to 64.19%, and we found the occurrence of section Nigri species on the surface of fresh grapes was significantly influenced by the climate (P<0.05). The subtropical monsoon climate showed the highest fungal detection rate (72.45%), followed by the temperate monsoon climate (49.82%), and the lowest frequency was found in the temperate continental climate (37.23%). Regarding mycotoxin-producing capacity, 4.4% of the total tested section Nigri isolates (137) were positive for ochratoxin A (OTA) production and 59.6% were fumonisin B2 (FB2) producers. Of those, Aspergillus carbonarius was the main OTA producer and A. welwitschiae and Aspergillus niger were the main FB2 producers with different toxigenic ability. Our results highlight the potential risk of OTA and FB2 contamination by A. carbonarius and A. welwitschiae on grape in China, respectively; management strategies should be considered for preventing and reducing the toxigenic Aspergillus and its mycotoxins.

Abstract
AIM To undertake a systematic review and meta-analysis of the diagnostic performance of CT for differentiating peritoneal tuberculosis (PTB) from peritoneal carcinomatosis (PC). MATERIAL AND METHODS PubMed, Embase, the Web of Science, and the Cochrane Library were searched for papers published before 23 July 2019. The methodological quality of the studies was analysed. Overlapping descriptors used in different studies to denote the same image finding were subsumed under a single CT feature. Sensitivity, specificity, and positive and negative likelihood ratios were pooled. A summary receiver operating characteristic curve (sROC) was constructed and the area under the curve (AUC) of the included studies was calculated when possible. RESULTS Six studies were included and 17 CT features were analysed. The pooled sensitivity and specificity of smooth peritoneal thickening were 59% (95% CI: 52-66%) and 84% (95% CI: 79-88%), respectively. The AUC of smooth peritoneal thickening was 0.83. Omentum line/rim, lymph node necrosis or calcification, and mesenteric macro nodules had a pooled specificity ranging from 95% to 100% and a pooled sensitivity ranging from 12% to 67%. The other 12 signs had a pooled sensitivity ranging from 21% to 79% and a pooled specificity ranging from 19% to 81%. Omentum involvement (cake-like pattern) showed a threshold-effect, so only the AUC (=0.70) was calculated. CONCLUSIONS Smooth peritoneal thickening shows fairly good diagnostic accuracy, while omentum rim/line, lymph nodes necrosis or calcification, mesenteric macro nodules have good specificity but limited sensitivity. The informative features summarised in this study may aid clinical practice and future studies.

Abstract
The magnetoelectric properties of exchange-coupled Ni/CoFeB-based composite multiferroic microstructures are investigated. The strength and sign of the magnetoelastic effect are found to be strongly correlated with the ratio between the thicknesses of two magnetostrictive materials. In cases where the thickness ratio deviates significantly from one, the magnetoelastic behavior of the multiferroic microstructures is dominated by the thicker layer, which contributes more strongly to the observed magnetoelastic effect. More symmetric structures with a thickness ratio equal to one show an emergent interfacial behavior which cannot be accounted for simply by summing up the magnetoelastic effects occurring in the two constituent layers. This aspect is clearly visible in the case of ultrathin bilayers, where the exchange coupling drastically affects the magnetic behavior of the Ni layer, making the Ni/CoFeB bilayer a promising next-generation synthetic magnetic system entirely. This study demonstrates the richness and high tunability of composite multiferroic systems based on coupled magnetic bilayers compared to their single magnetic layer counterparts. Furthermore, because of the compatibility of CoFeB with present magnetic tunnel junction-based spintronic technologies, the reported findings are expected to be of great interest for the development of ultralow-power magnetoelectric memory devices.

Abstract
PURPOSE Radiotherapy is the main treatment method for patients with locally advanced, unresectable esophageal cancer. The aim of this study is to compare overall survival (OS) using 3D radiotherapy (3DRT) alone with concurrent chemoradiotherapy (CCRT) in 296 non-surgical esophageal carcinoma patients. PATENTS AND METHODS Over 10 years, of the 480 patients with esophageal carcinoma treated with 3DRT with or without chemotherapy, 148 patients each comprised 3DRT and CCRT groups after propensity score matching. RESULTS The 5- and 10-year OS (P=0.337) and PFS (P=0.715) rates for 3DRT alone were 22.0%, 14.4% and 26.1%, 23.2%, respectively, compared with 28.8%, 18.6% and 34.7%, 29.1% for CCRT, respectively. CCRT did not improve 5-year and 10-year OS or PFS in 60-70Gy group (OS: 27.5% and 25.2%; 17.9% and 17.0%, P=0.938; PFS: 38.3% and 31.8%; 31.9% and 27.8%, P=0.890) nor reduce 10-year hematogenous metastasis (31.7% and 28.3%, P=0.698). CCRT improved 5-year OS and PFS of 50.0-59.9Gy group (OS: 33.3% and 12.0%, P=0.029; PFS: 33.1% and 10.6%, P=0.081). For 3DRT, the 5-year OS and PFS rates were significantly better in the 60-70Gy group (P=0.017) compared with 50.0-59.9Gy group (P=0.002). For CCRT group, 5-year OS and PFS favored the 50.0-59.9Gy group, but the difference was insignificant. Major toxicities were greater with CCRT compared with 3DRT. CONCLUSION For non-surgical esophageal carcinoma patients, 3DRT combined with CCRT was effective in prolonging both OS and PFS.

Abstract
The electrical resistivity of single-layer graphene nanoribbons has been studied experimentally for ribbon widths from 16 to 320 nm and is shown to validate the expected quantum scattering model for conduction through confined graphene structures. The experimental findings are that the resistivity follows a more dramatic trend than that seen for metallic nanowires of similar dimensions, due to a combination of the nature of the charge carriers in this 2D material, surface scattering from the edges, bandgap related effects and shifts in the Fermi level due to edge effects. We show that the charge neutrality point switches polarity below a ribbon width of around 50 nm, and that at this point, the thermal coefficient of resistance is a maximum. The majority doping type therefore can be controlled by altering ribbon width below 100 nm. We also demonstrate that an alumina passivation layer has a significant effect on the mean free path of the charge carriers within the graphene, which can be probed directly via measurements of the width-dependent resistivity.

Abstract
PURPOSE Prolactinoma is the most commonly seen secretory tumor of pituitary glands, which accounts for approximately up to 40% of total pituitary adenomas. Due to its high drug resistance, dopamine agonist, such as bromocriptine, has limited effect on the treatment of patients with prolactinoma. Recent discoveries have revealed that multiple miRNAs were involved in regulating drug resistance. In this research, we explored the relationship between miR-145-5p expression as well as bromocriptine sensitivity both in vitro and in vivo. METHODS To study the role of miR-145-5p in drug resistance of prolactinoma, the expression levels of miR-145-5p in bromocriptine-resistant prolactinoma cell line MMQ/BRC and its parental cell line MMQ cells, 24 bromocriptine-resistant as well as eight sensitive clinical samples were measured by qRT-PCR. Moreover, CCK8, flow cytometry and immunofluorescence were performed to identify the biological characteristics of MMQ/BRC and MMQ. TPT1 was predicted as a direct target gene of miR-145-5p by bioinformatic methods. In addition, qRT-PCR, western blot and immunohistochemistry were used to detect the expression level of TPT1 in clinical specimens and cell lines. Xenograft mouse model was constructed to analyze whether miR-145-5p could reverse bromocriptine resistance in prolactinoma in vivo. RESULTS In our study, bromocriptine-resistant prolactinoma clinical samples and cell line had decreased miR-145-5p levels and expressed high levels of TPT1 compared with their sensitive counterparts. Bioinformatic methods and our preliminary dual luciferase reporter assay were utilized to elucidate that TPT1 was a direct target gene of miR-145-5p. Furthermore, introducing miR-145-5p mimic into MMQ cells led to a decrease of IC50 along with upregulation of TPT1; nevertheless, transfecting the corresponding inhibitor into MMQ cells resulted in an upregulation of IC50 as well as reduction of TPT1. CONCLUSIONS Collectively, our findings elucidated the role of miR-145-5p as an important regulator of drug resistance in prolactinoma by controlling TPT1, and implicated the potential application of miR-145-5p in cancer therapy as well.

Abstract
BACKGROUND Slow freezing has been widely applied to preserve human ovarian tissue. OBJECTIVE The aim of this study is to determine whether human ovarian cortex pretreated with hyaluronidase can improve the protective effect of cryopreservation. MATERIALS AND METHODS Human ovarian biopsies from seven patients were cryopreserved using slow freezing. The samples in the experimental group were incubated in culture medium with hyaluronidase for a short time before cryopreservation. The histology of the thawed ovarian tissue was investigated; the levels of steroid hormone in the culture media were then used to evaluate the development and function of thawed ovarian tissue. RESULTS The result showed that the percentage of morphologically abnormal primordial follicles was higher in the freezing control than in the experimental group (P<0.05). 17β-estradiol (E2) and progesterone (P4) concentrations were significantly higher in the experimental group than in the freezing control group (P<0.05). CONCLUSION Our study showed that human ovarian cortex pretreatment with hyaluronidase can improve the protective effect of cryopreservation by improving the penetration of cryoprotectant.
