Abstract
Background Systematic retroperitoneal lymphadenectomy has been widely used in the surgical treatment of advanced ovarian cancer patients. Nevertheless, the corresponding therapeutic may not provide a survival benefit. The aim of this study was to assess the effect of systematic retroperitoneal lymphadenectomy in such patients. Methods Patients with advanced ovarian cancer (stage III-IV, according to the classification presented by the International Federation of Gynecology and Obstetrics) who were admitted and treated in Zhejiang Cancer Hospital from January 2004 to December 2013 were enrolled and reviewed retrospectively. All patients were optimally or suboptimally debulked (absent or residual tumor <1 cm) and divided into two groups. Group A (no-lymphadenectomy group, n =170): patients did not undergo lymph node resection; lymph nodes resection or biopsy were selective. Group B (n=240): patients underwent systematic retroperitoneal lymphadenectomy. Results A total of 410 eligible patients were enrolled in the study. The patients’ median age was 51 years old (range, 28–72 years old). The 5-year overall survival (OS) and 2-year progression-free survival (PFS) rates were 78% and 24% in the no-lymphadenectomy group and 76% and 26% in the lymphadenectomy group (P=0.385 and 0.214, respectively). Subsequently, there was no significant difference in 5-year OS and 2-year PFS between the two groups stratified to histological types (serous type or non-serous type), the clinical evaluation of negative lymph nodes or with macroscopic peritoneal metastasis beyond pelvic (IIIB-IV). Multivariate Cox regression analysis indicated that systematic retroperitoneal lymphadenectomy was not a significant factor influencing the patients’ survival. Patients in the lymphadenectomy group had a higher incidence of postoperative complications (incidence of infection treated with antibiotics was 21.7% vs. 12.9% [P=0.027]; incidence of lymph cysts was 20.8% vs. 2.4% [P < 0.001]). Conclusions Our study showed that systematic retroperitoneal lymphadenectomy did not significantly improve survival of advanced ovarian cancer patients with residual tumor<1 cm or absent after cytoreductive surgery, and were associated with a higher incidence of postoperative complications.

Abstract
Background: LncRNA MEG3 expressed abnormally in various cancers including breast cancer, but no studies reported the correlation between MEG3 SNPs and breast cancer susceptibility among Chinese women. Methods: This study is aimed to explore the association between three SNPs of MEG3 (rs3087918, rs7158663, rs11160608) and breast cancer. The study is a population-based case-control study including 434 breast cancer patients and 700 healthy controls. Genotyping was performed using Sequenom MassArray technique. Function prediction of rs3087918 were based on RNAfold and lncRNASNP2 databases. Results: Pooled analysis indicated that rs3087918 was related to a decreased risk of breast cancer [GG vs. TT: OR(95%) = 0.67(0.45-0.99), P = 0.042; GG vs. TT + TG: OR(95%) = 0.69(0.48-0.99), P = 0.046], especially for women aged <=49 [GG vs. TT: OR(95%) = 0.40(0.22-0.73), P = 0.02]. Comparison between case groups showed genotype GG and TG/GG of rs3087918 were associated with her-2 receptor expression [GG vs. TT: OR(95%) = 2.37(1.24-4.63), P = 0.010; TG + GG vs. TT: OR(95%) = 1.50(1.01-2.24), P = 0.045]. We didn’t find statistical significance for rs11160608, rs7158663 and breast cancer. Structure prediction based on RNAfold found rs3087918 may influence the secondary structure of MEG3. The results based on lncRNASNP2 indicated that rs3087918 may gain the targets of hsa-miR-1203 to MEG3, while loss the target of hsa-miR-139-3p and hsa-miR-5091 to MEG3. Conclusions: MEG3 rs3087918 was associated with a decreased risk of breast cancer. MEG3 haplotype TCG may increase the risk of breast cancer.

Abstract
Background: The underlying cellular mechanisms causing adverse reactions to food are complex and still not fullyunderstood. Therefore, in this study we aimed to identify functional and/or phenotypical immune cell signaturescharacteristic for adult patients reporting adverse reactions to food.By mass cytometry, we performed high-dimensional profiling of peripheral blood mononuclear cells (PBMC) fromadult patients reporting adverse reactions to food and healthy controls. The patients were grouped according to sIgE-positive or sIgE-negative serology to common food and inhalant allergens. Two broad antibody panels were used,allowing determination of major immune cell populations in PBMC, as well as activation status, proliferation status,and cytokine expression patterns after PMA/ionomycin-stimulation on a single cell level.Results: By use of data-driven algorithms, several cell populations were identified showing significantly differentmarker expression between the groups.Most striking was an impaired frequency and function of polyfunctional CD4+ and CD8+ T cells in patients reportingadverse reactions to food compared to the controls. Further, subpopulations of monocytes, T cells, and B cells hadincreased expression of functional markers such as CD371, CD69, CD25, CD28, and/or HLA-DR as well asdecreased expression of CD23 in the patients. Most of the differing cell subpopulations were similarly altered in thetwo subgroups of patients.Conclusion: Our results suggest common immune cell features for both patient subgroups reporting adversereactions to food, and provide a basis for further studies on mechanistic and diagnostic biomarker studies in foodallergy.

Abstract
Background: The present study provides a countrywide perspective of the malaria situation in Panama over a long-term framework, with the purpose of identifying historical malaria resurgence events and their potential causes. Methods: A descriptive-ecological study was conducted by analyzing demographic and epidemiological annual malaria time series data in Panamá (1884 – 2019) using several data sources. Malaria intensity indicators were calculated during the study period. We also analyze the effects of El Niño Southern Oscillation on malaria transmission using a retrospective analysis of malaria cases between 1957 and 2019. Results: Several factors were identified responsible for malaria resurgence in Panama, mostly related with Malaria Control Programme weakening. During the past 20 years (2000 – 2019) malaria has progressively increased its prevalence within indigenous settlements, with a predominance of male cases and a high proportion (15% of total cases) in children less than 5 years old. During this period a significant and increasing proportion of the P. falciparum total cases were imported. Our retrospective analysis (1957 - 2019) evidenced that ENSO has a significant impact on malaria transmission dynamics in Panama. Conclusions: Data analysis confirmed that although authorities have been successful in focalizing malaria transmission in the country, there are still neglected issues to be solved and important intercultural barriers that need to be addressed in order to achieve elimination of the disease by 2022. This information will be useful for targeting strategies by the National Malaria Control Programme.

Abstract
Objective: The role of Mycobacterium tuberculosis complex (MTBC) species in tuberculosis (TB) infection in human is still questioned. The aim of this study was to determine whether M. tuberculosis and M. bovis is associated with apoptosis and necroptosis by measuring the expression of specific signaling pathways components (Fas-associated protein with death domain (FADD) and receptor interacting protein 3 (RIP3)), and the level of apoptosis.Results: We recruited 30 patients of pulmonary TB; 24 patients were infected with M. tuberculosis Beijing strain and six patients with M. bovis BCG strain. M. tuberculosis-infected patients were more likely to have severe lung damage compared to those infected with M. bovis (odds ratio [OR]: 7.60; 95% confidence interval [CI]: 1.07-54.09). M. tuberculosis infection was associated with lower expression of FADD and lower apoptosis level of macrophages compared to M. bovis. No significant different of RIP3 between MTBC species groups. In conclusion, M. tuberculosis Beijing strain was associated with severe pulmonary damage, inhibited FADD expression and reduced apoptosis level of macrophages derived from TB. This suggests that the M. tuberculosis Beijing strain is potentially to be used as determinant of disease progressivity and tissue damage in TB cases.

Abstract
Background: Ovarian cancer (OvCa) is one of the most lethal tumors of gynecologic malignancies, due to lack of early detection, and a high rate of metastasis. The standard treatment for OvCa is surgery and cytotoxic chemotherapy. However, to overcome the high cost and side effects of these treatments, medicinal plants are widely used in developing countries to treat OvCa. Byrsocarpus coccineus plant preparation has been administered to patients traditionally in the management of tumors in Nigeria. In this study, we investigated the anti-proliferative effects of B. coccineus ethanol leaf extract against OVCAR-3 and SW 626 OvCa cell lines. After the treatment of the two cell lines with the extracts, analyses were carried out to determine inhibition of proliferation and expression of cell cycle markers, pro-apoptotic, and anti-apoptotic markers. Results: Results showed that B. coccineus ethanol leaf extract, significantly inhibited cell migration and colony formation in OVCAR-3 and SW 626 treated cells in a dose-dependent manner. Results also show that B. coccineus ethanol leaf extract modulated the expression of tumor suppressor gene (p53), cell cycle progression, pro- and anti-apoptotic gene, and the pro-inflammatory cytokines. Conclusions: These results suggest that B. coccineus have anti-proliferative properties and could induce apoptosis. Further investigation will be carried out to isolate bioactive compounds for the treatment of ovarian cancer.

Abstract
Background

A sustainable breeding program requires a minimum level of germplasm diversity to provide varied options for the selection of new breeding lines. To maximize genetic gain of the North Dakota State University (NDSU) flax breeding program, we aimed to increase the genetic diversity of its parental stocks by incorporating diverse genotypes. For this purpose, we analyzed the genetic diversity, linkage disequilibrium, and population sub-structure of 350 globally-distributed flax genotypes with 6,200 SNP markers

Results

All the genotypes tested clustered into seven sub-populations (P1 to P7) based on the admixture model and the output of neighbor-joining (NJ) tree analysis and principal coordinate analysis were in line with that of structure analysis. The largest sub-population separation arose from a cluster of NDSU/American genotypes with Turkish and Asian genotypes. All sub-populations showed moderate genetic diversity (average H = 0.22 and I = 0.34). The pairwise F st comparison revealed a great degree of divergence ( F st > 0.25) between most of the combinations. A whole collection mantel test showed significant positive correlation (r = 0.30 and p < 0.01) between genetic and geographic distances, whereas it was non-significant for all sub-populations except P4 and P5 (r= 0.251, 0.349 respectively and p < 0.05). In the entire collection, the mean linkage disequilibrium was 0.03 and it decayed to its half maximum within < 21 kb distance.

Conclusions

To maximize genetic gain, hybridization between NDSU stock (P5) and Asian individuals (P6) are potentially the best option as genetic differentiation between them is highest ( F st > 0.50). In contrast, low genetic differentiation between P5 and P2 may enhance the accumulation of favorable alleles for oil and fiber upon crossing to develop dual purpose varieties. As each sub-population consists of many genotypes, a Neighbor-Joining tree assists to identify distantly related genotypes. These results also inform genotyping decisions for future association mapping studies to ensure the identification of a sufficient number of molecular markers to tag all linkage blocks.

Published: July 2020

Abstract
Background: Wnt-inducible signaling pathway protein 2 (WISP2) is a wnt1-induced signaling pathway protein 2. Although studies indicate that WISP2 may promote the development of various tumors, its role in ovarian cancer remains unclear. The objective of the current study was to analyze the effects of WISP2 on the proliferation and migration of ovarian cancer cells in vitro and in vivo.Results: Immunohistochemistry and western blotting indicated that WISP2 was highly expressed in various ovarian cancer tissues and cell lines，but weakly expressed in normal ovary tissue. WISP2 deletion inhibited cell growth, clone formation, and migration of ovarian cancer cells while promoting cell apoptosis and affecting the cell cycle. This growth inhibitory effect caused by WISP2 loss is due to the inhibition of phosphorylated extracellular signal-related kinase (p-ERK)1/2, as well as CCAAT/enhancer-binding protein α (CEBPα) and CEPBβ. In addition, WISP2 deletion also activated the Yes-associated protein (YAP).Conclusion: WISP2 deletion inhibits ovarian cancer cell proliferation by affecting ERK signaling pathways.

Abstract
Background: Artemisinin is widely used to anti malaria, but the antimalaria mechanism and coordinative interaction of Artemisinin, Scopoletin, Arteannuin B and Artemisic acid are not clear.Methods: Based on the existing of antimalarial drugs, the antimalaria targets of Artemisinin, Scopoletin, Arteannuin B and Artemisic acid were explored by molecular docking with the similarity theory of chemical structure, and then the antimalaria mechanism of Scopoletin and its coordinative antimalaria interaction of the mixture with the three other ingredients.Results: Then through using the text information excavation’s method, the relevance proteins of antimalaria effect of Artemisinin were IL-6, ACHE, PC3, IPOB, CYC, TNF-α, UGT1A9, CASP3, XDH, IL-1β, VEGF, CAT, CREB, AMPK, UGT1A6, ADR, MAPK, COX2, LB24AB and CYP450. Meanwhile, the relevance proteins of Scopoletin were TNF-α, PI3K, IL-8, IL- 6, VEGF, IL-1β, MAPK, CD4, SP2, CTNNB, CASP3, PRO1400, IgE, IL-4, ICAM1, p38, STAT3, TLR4 and API4. But Arteannuin B and Artemisic acid had a little relevance with the above proteins. The interaction characteristic between TNF-α and Artemisia annua was the effect of the mixture of Artemisinin, Scopoletin, Arteannuin B and Artemisic acid was greater than Artemisinin, and the synergistic effect of the four elements was found in the progress of antimalaria.Conclusion: Antimalarial target of Artemisia annua ingredients was explored with data mining methods, and the antimalarial effect of Scopoletin may be related to TNF. Combined application of the four elements could achieve the same antimalarial effect and reduce the clinical usage of Artemisinin and Scopoletin.

Abstract
Objective: To evaluate the impact of AIDS-defining events (ADE) on long-term mortality of HIV positive individuals on antiretroviral therapy (ART), a retrospective HIV/AIDS treatment cohort study performed in Southwestern China.

Methods: The retrospective cohort was conducted among 6757 HIV/AIDS patients on ART (2NRTIs+1NNRTI, 2NRTIs+1PI and Single or two drugs) recruited in Guigang city, Guangxi, China, from January 2004 to December 2018. Participants were divided into ADE and non-ADE groups, and were followed-up every six months to observe treatment outcomes. Comparison of mortality between groups was performed using the log-rank test and Kaplan-Meier analysis. Cox proportional hazard regression was used to explore the risk factors of mortality. 1:1 propensity score matching (PSM) was used to balance confounding factors and adjust the mortality risk.

Results: Of 6,757 participants with 29,096.06 person-years of follow-up, 16.86% (1,139/6,757) belonged to ADE group while the others (83.14%) belonged to the non-ADE group. The most common cause of death by ADE was disseminated mycosis (31.65%), followed by recurrent severe bacterial pneumonia (28.48%), herpes zoster (17.72%), and extra-pulmonary tuberculosis (8.86%). The mortality of the ADE group was significantly higher than that of the non-ADE group [3.45/100 person-years (95% CI: 2.92-3.97) vs. 2.34/100 person-years (95%CI: 2.15-2.52), P＜0.001]. The death risk of the ADE group was also higher than that of the non- ADE group [adjusted hazard ratio (aHR) =1.291, 95% CI: 1.061-1.571, P=0.011], which was confirmed by PSM analysis (aHR=1.581, 95% CI: 1.192-2.099, P=0.002). Cox analysis indicated that ADE, older age, male gender, previous non-use of cotrimoxazole, advanced WHO clinical stage, and low baseline CD4+ cell count were the risk factors for death.

Conclusions: Even on ART, the mortality risk of HIV positive individuals with ADE was higher than those without ADE. Active testing, earlier diagnosis, and timely therapy with ART may reduce the death risk of ADE.

Published: July 2020

Abstract
The high enthalpy nozzle converts the high enthalpy stagnation gas into the hypervelocity free flow. The flow region of the high enthalpy nozzle consists of three parts: an equilibrium region upstream of the throat, a non-equilibrium region near the throat, and a frozen region downstream of the throat. Here we propose to consider the thermochemical non-equilibrium scale effects in the high enthalpy nozzle. With numerical solving axisymmetric compressible Navier-Stokes equations coupling with Park’s two-temperature model, the fully non-equilibrium solution is employed throughout the entire nozzle. Calculations are performed at different stagnation conditions with the different absolute scales and expansion ratio. The results of this study contain twofold. Firstly, as the absolute scale and expansion ratio increase, the freezing position is delayed, and the flow approaches equilibrium. Secondly, the vibrational temperature and Mach number decrease with the increase in the nozzle scale and expansion ratio，while the speed of sound, static pressure, and translational temperature increase as the nozzle scale and expansion ratio increase.

Abstract
Background The surgical Apgar score (SAS) or modified SAS (mSAS) has been reported as a simple and easy risk assessment system for predicting postoperative complications in primary surgery for gastric cancer. However, few studies have described the SAS’s utility in gastric surgery after neoadjuvant chemotherapy (NAC).Methods One hundred and fifteen patients who received NAC and radical gastrectomy from 2008 and 2015 were included in this study. The SAS was determined by the estimated blood loss (EBL), lowest intraoperative mean arterial pressure, and lowest heart rate. The mSAS was determined by the EBL reassessed using the interquartile values. The predictive values of the SAS/mSAS for postoperative complications were assessed with univariate and multiple logistic regression analyses.Results Among the 115 patients, 41 (35.7%) developed postoperative complications. According to analyses with receiver operating characteristic curves of the SAS and mSAS for predicting postoperative complications, the cut-off value of the mSAS was set at 8. The rates of anastomotic leakage, pancreatic fistula, and arrhythmia in patients with high mSAS (>8) values were higher than in those with low (0-3) and moderate (4-7) mSAS values. A multiple logistic regression analysis showed that the operation time, body mass index, and diabetes mellitus were independent risk factors for postoperative complications. The mSAS was not a significant predictor.Conclusion The predictive value of SAS or mSAS for morbidity may be limited in patients who undergo gastric cancer surgery after NAC. Future prospective studies with a large sample size will be needed to confirm the present results.
