Abstract
Background: The aim of the study is to investigate the success rate of ECV and relevant complications with intrathecal analgesia for singleton breech pregnancy.Methods: Sixty pregnant women received obstetrical regular prenatal care were randomly divided into EA group( epidural anesthesia, n = 30), CSEA group( combined spinal-epidural anesthesia, n = 30), control group(no analgesia, n = 30). The primary outcome of our study was the success rate of ECV confirmed by ultrasound. Visual analogue scale,, the rate of cesarean section and relevant side effect were recorded.Results: The success rate of spontaneous inversion to cephalic version was 76.7% in EA group, which was higher than that in CSEA group (53.3%) and control group (46.7%) (p = 0.058 and p = 0.017, respectively). The rate of cesarean section in EA group was 33.3%, which was also lower than that in CSEA group (53.3%) and control group (50.0%), however, the difference was not statistically significant between CSEA group and EA group(p = 0. 19). The VAS scores in the EA group and the spinal group were respectively 1.87 ± 2.94 and 1.73 ± 2.71 ,obviously better than that of the control group (6.84 ± 3.08) (p = 0.001 and p = 0.001).It was no significant difference between EA group and Control group ( p = 0. 118). The incidence of hypotension, nausea and vomiting, and fetal heart rate deceleration in CSEA group was significantly higher than that in control group (p = 0.000, p = 0.161, p = 0.129). The occurrence rate of spontaneous fetal heart rate deceleration in the EA, CSEA and control group were 6.7%, 20% and 6.7%, respectively, the differences were not statistically significant.Conclusions: EA can be more effective to enhance the success rate of spontaneous inversion to cephalic version than CSEA, and CSEA is accompanied with more side effects. Meanwhile, EA or CSEA don’t affect the rate of cesarean section of ECV for breech single pregnancy.

Abstract
Background

Non-small cell lung cancer (NSCLC), is the most common malignancy worldwide. MiR-199a-5p has been reported to play important roles in multiple tumors, inclusive of NSCLC. Whereas, little is definitively known pertaining to its explicit mechanism of action in NSCLC.
Methods

Expression of miR-199a-5p and HIF-1α mRNA were quantified employing qRT-PCR. H1299 and A549 cells were transiently transfected with miR-199a-5p mimics or inhibitors. Then CCK-8 assays, flow cytometry analysis, Transwell assay were implemented for detecting cell proliferation, cell cycle, apoptosis, migration and invasion of NSCLC cells, respectively. HIF-1α, STAT3 and p-STAT3 expression were detected via Western blotting. Bioinformatic analysis and dual-luciferase assay were performed for monitoring interaction between miR-199a-5p, HIF-1α and STAT3. Xenograft models were established with nude mice for further analyzing Bevacizumab resistance of NSCLC.
Results

MiR-199a-5p expression was markedly attenuated in NSCLC tissues and cell lines. Overexpression of miR-199a-5p constrained proliferation, migration, invasion but induced apoptosis of NSCLC cells. HIF-1α was identified as a direct target of miR-199a-5p. Further study confirmed a positive feed-back loop between miR-199a-5p, HIF-1α and STAT3. Co-transfection of HIF-1α or STAT3 overexpression plasmids counteracted effects of miR-199a-5p. Further study substantiated that feed-back loop might be in association with the Bevacizumab resistance of NSCLC cells .
Conclusion

MiR-199a-5p constrained the progression and Bevacizumab resistance of NSCLC by suppressing HIF-1α and STAT3, while HIF-1α/STAT3 axis suppressed the expression of miR-199a-5p, which forms a positive feed-back loop to promote the sustaining progression of NSCLC.

Abstract
Objective: To explore the feasibility of adjuvant surgery following concurrent chemoradiation therapy (CCRT) in stage ⅡB–Ⅲ cervical cancer. And analyze risk factors of recurrence after surgery. Methods: Forty-nine patients diagnosed with stage ⅡB–Ⅲ cervical cancer were reviewed retrospectively. Investigated the risk factors of recurrence after surgery using Chi-squared Test and further analyzed multiple factors affecting postoperative recurrence using the multi-factor logistic regression. Furthermore, the correlation of surgery outcomes (including operation time, bleeding, and hospitalization date and surgery complications) with the time which carried out between CCRT and completion surgery was analyzed. Results: Tumor histology and residual tumor in the cervix were significantly associated with postoperative recurrence (P = 0.014 and P = 0.040, respectively). Logistic regression analysis demonstrated that the independent risk factors of postoperative recurrence were age and residual tumor in the cervix (P = 0.017 and P = 0.030, respectively). Compared with completion surgery was carried out ≤ 6 weeks after CCRT, the operation time, bleeding, hospitalization date and surgery complications were more than > 6 weeks group. Moreover, bleeding and surgery complications were statistically significant (P = 0.019 and P = 0.044, respectively).Conclusion: CCRT combined surgery for stage ⅡB–Ⅲ cervical cancer was feasible, reduced the rate of postoperative recurrence and surgery complications were tolerated. CCRT combined surgery might improve the local control of lesion.

Abstract
Premature ovarian insufficiency (POI) is characterized by impairment of ovarian function on a continuum before the age of 40 years. POI is affected by multiple factors. Considering new insights from recent gut microbiome studies, this study aimed to investigate the relationship between gut microbial community structure and POI. Subjects were recruited at the Shenzhen Maternity&Child Healthcare Hospital. Fecal microbial community profiles of healthy women (n = 18), women with POI (n = 35) were analyzed using 16S rRNA gene sequencing based on Illumina NovaSeq platform. Compared to the controls, the serum levels of FSH, LH, T and FSH/LH ratio significantly increased in women with POI, whereas E2 and AMH decreased significantly. Higher weighted UniFrac value was observed in POI women compared with healthy women. Phylum Firmicutes, genera Bulleidia and Faecalibacterium were more abundant in healthy women, while phylum Bacteroidetes, genera Butyricimonas, Dorea, Lachnobacterium and Sutterella enriched significantly in women with POI. Moreover, these alterations of the gut microbiome in women with POI was closely related to FSH, LH, E2, AMH level and FSH/LH ratio. Women with POI had altered microbial profiles in their gut microbiome, which were associated with serum hormones levels. These results will shed a new light on the pathogenesis and treatment for POI.

Published: August 2020

Abstract
Background: The integration of multi-omics data can greatly facilitate the advancement of research in Life Sciences by providing new insights on how biological systems interact. However, there is currently no widespread procedure for a robust, efficient and meaningful multi-omics data integration; the approach presented here is a first attempt towards increasing the reliability of data discovery power compared to the processing of individual biodata sets. Results: Here, we proposed a high-speed framework, called InterTADs, for integrating multi-omics data from the same physical source (e.g. patient) taking into account the chromatin configuration of the genome, i.e. the topologically associating domains (TADs). The main concept of the proposed methodology is to create a single matrix with all different events (e.g. DNA methylation, expression, mutation) combined with their genome coordinates and the respective quantitative metrics after application of the appropriate scaling. The events are divided into their related TADs according to the chromosomal location and each TAD is evaluated for statistically significant differences between the groups of interest (e.g. normal cells vs cancer cells). Finally, several visualization approaches are available, including the mapping of the events on the chromosomal location of the TAD as well as the distribution of the counts within a given TAD across the different study groups.Conclusions: InterTADs provides a general framework for integrating multi omics data and relating them with the TADs. This could lead to the extraction of new biological insight of the examined case study. InterTADs is an open-source tool implemented in R and licensed under the MIT License.

Published: August 2020

Abstract
Aspergillus flavus and its main secondary metabolite AFB1 pose a serious threat to several important crops worldwide. Recently, it has been reported that some PHD family transcription factors are involved in the morphogenesis and AFB1 biological synthesis in A. flavus, but the role of Cti6, a PHD domain containing protein in A. flavus, is totally unknown. The study was designed to reveal the biological function of Cti6 in the fungus by deletion of cti6, and its two domains (PHD and Atrophin-1) through homologous recombination, respectively. The results showed that Cti6 might up-regulate the mycelium growth, conidiation, sclerotia formation and AFB1 biological synthesis of A. flavus by its PHD domain, while Atrophin-1 also improved the conidiation of the fungus. The qRT-PCR analysis showed that Cti6 increased the conidiation of the fungus through AbaA and BrlA mediated conidiation pathway, triggered the formation of sclerotia by orthodox sclerotia formation pathway, and improved the production of AFB1 by orthodox AFB1 synthesis pathway. Crops models analysis showed that A. flavus Cti6 plays vital role in colonization and the production of AFB1 on the host grains mainly via PHD domain. Bioinformatics analysis showed Cti6 is conservative in Aspergillus spp., and mCherry mediated subcellular localization showed that most Cti6 accumulated in the nuclei, which reflected that Cti6 performed its important biological function in the nuclei in Aspergillus spp.. The results of the current study elucidate the roles of PHD domain containing proteins in the mechanism of the infection of crops by A. flavus, and provided a novel target for effectively controlling the contamination of Aspergillus spp. to crops.

Abstract
Background: The human papillomavirus (HPV), especially HPV 16 type infection, is one of the well-known causes for human cervical cancer, we sought to investigate HPV 16 regulating lncRNA and its role in cervical carcinogenesis. Methods: The potential HPV16 related lncRNAs were screened by using bioinfomatic analysis. The relationship between SOX21-AS1 and clinical features was studied by using clinical samples. Its oncogenic roles were explored in vitro. Results: A HPV 16 infection-specific lncRNA, SOX21-AS1 was spotted by screening the Cancer Genome Atlas TCGA database, and its expression was seriously related to Hippo signaling pathway by using Gene Set Enrichment Analysis. Total 40 cases patients suffered from cervical carcinomas (CCs) were involved, we found that SOX21-AS1 was over-expressed in those CCs patients who were positive for HPV 16 infection compared to those who were negative. We also found that SOX21-AS1 expression was positively related to E6 protein but not E7 expression, which is a carcinogenic protein of HPV 16. Also, YAP1/TAZ/TEAD complex can increase SOX21-AS1 transcription by binding to its promoter region. SOX21-AS1 can promote cell proliferation and invasion in CCs cell lines in a YAP1 activation-dependent manner. We found that SOX21-AS1 can promote YAP1 activation by preventing YAP1 phosphorylation at s127 residue and further preventing its degradation by binding to 14-3-3. Conclusion: In conclusion, SOX21-AS1 is an HPV16 specific lncRNA which can promote tumor growth and metastasis by targeting the Hippo signaling pathway.

Abstract
Background

Triplet therapy has become the standard of care for relapsed or refractory multiple myeloma (RRMM) over the past few years. Prior to that, doublet therapy including dexamethasone and an immunomodulatory were standard. Several systematic studies have been conducted and many combinations with variable triplet therapies but have not always used the former standard therapy as a benchmark. The objective of this meta-analysis was to evaluate the efficacy and safety of triplet combinations that included dexamethasone and an immunomodulatory drug versus a doublet combination of just dexamethasone and an immunomodulatory for the treatment of RRMM.
Methods

A comprehensive literature search (PubMed, EMBASE, Cochrane Library) for phase III randomized controlled trials for efficacy and safety of triplet versus doublet combinations that specifically included dexamethasone and an immunomodulatory drug for treatment of RRMM. Efficacy (ORR, PFS, OS) and adverse events (≥ grade 3) were assessed using traditional statistical measures for aggregate data.
Results

Of 235 potential reports, 6 met the inclusion criteria (N = 115–792 participants). The methodological quality was ≥ 4 Jadad score for each. Triplet treatment had higher ORR (HR = 0.74, 95%CI: 0.65–0.84, P ≤ 0.001), PFS (HR = 0.63, 95%CI: 0.52–0.75, P ≤ 0.001), and OS (HR = 0.74, 95%CI: 0.65–0.84, P ≤ 0.001). The incidence of ≥ grade 3 diarrhea and fatigue were significantly higher in the triplet combination group. There was a trend toward increased incidence of ≥ grade 3 neutropenia, thrombocytopenia, thromboembolism, and peripheral neuropathy in the triplet therapy group. Notably, triplet therapy had a significantly lower rate of anemia compared to doublet therapy.
Conclusions

This study reinforces current guidelines and recommendations for triplet combinations containing dexamethasone and an immunomodulatory drug.

Abstract
Background

Diarrhea caused by parasitic agents is common in neonatal calves and causes significant economic losses in cattle farms worldwide. Cryptosporidium spp. is one of the most frequently detected parasitic agents causing diarrhea in neonatal calves. Also, Giardia intestinalis is shown to cause diarrhea in calves. This study aimed to investigate the presence of Cryptosporidium spp. in calves (n:36), cows (n: 11), drinking water and two different artesian water supplies as well as in environmental swap samples (n:32) obtained from the manger, silage, bottle, and doorknob in a dairy farm which has big diarrhea problems. For this purpose, all fecal samples investigated with using direct microscopy for routine parasitological screening. Then, the presence of Cryptosporidium spp. was examined in feces samples and other environmental samples using Kinyoun acid-fast stained slides and Real-Time PCR targeting Cryptosporidium spp.. In addition, Real-Time PCR positive samples were investigated by nested PCR and subsequently by sequencing, BLAST, and phylogenetic analysis for species identification by MEGA7.
Results

Giardia intestinalis was detected in 10 feces samples (21,27%; 10/47) during routine microscopic examination. Among them, 9 belonged to calves older than two months without diarrhea, and one belonged to an adult cow. Cryptosporidium spp. was found in 11 calves (30.55%; 11/36) by Real-Time PCR, whereas no cows were found positive. Among the PCR positive samples, only five of them were detected as positive by microscopy. Cryptosporidium spp. positivity value was found higher in younger than two month old calves with diarrhea (9/12; 75%). Also, Cryptosporidium spp. was found in one of two water supplies and five of environmental samples by real-time PCR. Of the 18 real time positive samples, 8 were found positive by nested PCR and all positive samples were detected to be Cryptosporidium parvum by sequencing, BLAST, and phylogenetic analysis.
Conclusions

Our findings showed the importance of C. parvum infection in diarrhea cases occurred in calves. Besides the correct diagnosis and treatment of Cryptosporidium spp. contaminated water resources, and hygiene measures are very important for preventing the cryptosporidiosis in dairy farms.
Impact of high non-performing loan ratios on bank lending trends and profitability
Authors: Jing Eric 
Published: August 2020

Abstract
The goal of this paper is to explore the relationship between the specific non-performing loan ratio (NPL ratio) and the corresponding impact on the bank’s profitability and lending behavior. It also seeks to investigate the macroeconomic impacts of economies with excessively high NPL ratios as well as the efficacy and impact of alleviation measures used by banks and governments around the world to help facilitate a decrease in high NPL ratios. The possible implications and effects of the COVID-19 pandemic on NPL ratios is also addressed in this paper. It is found that when excessively high NPL ratios go unaddressed, the economy tends to suffer. On the other hand, this study shows that when measures are taken to reduce or eliminate the high NPL ratios, economic performance improves, and the reduction has a clear positive impact on the economy.

Abstract
In this paper, we report complete design and simulation of a quasi-optical millimeter wave imaging system with Fresnel lens and horn Antenna using ZEMAX and FEKO softwares, respectively. It is much easier to make a Fresnel lens at millimeter wavelengths compared to spherical and aspherical lenses. The use of Fresnel lens to focus millimeter wave radiation greatly reduces the thickness and also the weight of the focusing element from 25 Kg to 4.5 Kg. A horn antenna with Gaussian profile and corrugated walls at the central frequency of 94 GHz for feeding this system is designed. The symmetry of the designed corrugated Gaussian horn radiation pattern in E and H orthogonal planes, its wide bandwidth as well as its low side lobe levels make it a good candidate for feeding a W band millimeter-wave imaging system. The designed quasi-optical imaging system has low weight with high resolution and can be used to detect hidden objects within a distance of 5 meters with 30 mm resolution in W band at 94 GHz central frequency.

Abstract
Objectives The aim of this study is to analyze the clinical and pathological features of HAS and investigate the factors affecting prognosis.Methods From January 2014 to May 2020, 31 patients were diagnosed as HAS in in the First Affiliated Hospital of Zhengzhou University. The clinicopathologic features and the relevant prognosis of these patients were analyzed.Results Of the 31 patients, 23 were male, with a median age of 62 years. And among the 31 patients, 22 patients underwent a radical gastrectomy and a D2 lymph node dissection. During the follow up period, 18 patients died of the disease. The median OS (mOS) was 28 months. The 1-year survival rate was 55%, the 3-year survival rate was 47%, and the 5-year survival rate was 34%. An elevated CA125 level, distant metastasis, and radical surgery were associated with the prognosis of HAS, and distant metastasis is an independent prognostic risk factor for survival. Conclusion HAS had a poor prognosis because of its frequent vascular involvement, and lymph node and liver metastasis. Aggressive multimodal treatment comprising radical gastrectomy and adjuvant chemotherapy is warranted.This article describes the Clinicopathological of Hepatoid Adenocarcinoma of the Stomach and through survival analysis, the factors affecting the patient’s prognosis were studied.

Authors: Zhang Weilin , Li Yong 
Published: August 2020

Abstract
Background: The tumor-node-metastasis (TNM) pN stage, which is based on the number of positive lymph nodes (LNs), is an important prognostic factor for patients with adenocarcinoma of the esophagogastric junction (AEG). The lymph node ratio (LNR) and log odds of metastatic lymph nodes (LODDS) staging systems are new effective indicators of prognosis. We aimed to evaluate their prognostic value in Siewert type II AEG.Methods: Patients diagnosed with Siewert type II AEG who underwent curative resection between 2004 and 2014 at Guangdong General Hospital were recruited. A Cox regression model was constructed, and prognostic performance was measured using Harrell’s concordance index (C-index) and the Akaike information criterion (AIC).Results: When LN status was modeled as a continuous variable, the LODDS system (C-index: 0.729; AIC: 940.483) outperformed the other staging systems, including the number of positive LNs (LNP) (C-index: 0.721; AIC: 946.935) and LNR (C-index: 0.725; AIC: 938.918).However,when assessed as categorical variables, the LNR staging system had a better prognostic performance (C-index: 0.752; AIC: 926.350) than the American Joint Committee on Cancer (AJCC) 8th edition TNM pN (C-index: 0.740; AIC: 934.349) and LODDS (C-index: 0.737; AIC: 939.087) staging systems. Each LNR stage is more evenly distributed than the other two staging systems. Moreover, the LODDS stage is more dependent on the TLNE.Conclusion: The LNR represented the best prognostic factor when assessed as a categorical variable and may serve as an alternative nodal staging system for AEG.
