Abstract
In this study, the impact of chitosan (CS) and maitake (GF) nanoparticles towards the renal toxicity induced by Ehrlich ascites carcinoma (EAC) in vivo model was conducted. Besides benchmark negative control group, EAC model was constructed by intraperitoneal injection (i.p.) of 2.5 × 106 cells. Alongside positive control, two groups of EAC-bearing mice received 100 mg/kg of CS and GF nanoparticles/body weight daily for 14 days. The kidney function was conducted by measuring urea, creatinine, ions, (anti)/oxidative parameters and DNA damage. Also, measuring immunoreactivity of P53, proliferating cell nuclear antigen (PCNA), and B-cell lymphoma 2 (Bcl-2) and apoptosis protein. The outcomes illustrated notable kidney toxicity, which indicated by elevations in urea, creatinine, oxidative stress, DNA damage and induction of apoptosis. These events were supported by the drastic alteration in kidney structure through histological examination. Administration of CS and GF nanoparticles was able to enhance the antioxidant power, which further reduced oxidative damage, DNA injury, and apoptosis. These results indicated the protective and therapeutic role of biogenic chitosan and maitake nanoparticles against nephrotoxicity.

Abstract
High-grade serous carcinoma of the ovary, fallopian tube and peritoneum (HGSC), the most common type of ovarian cancer, ranks among the deadliest malignancies. Many HGSC patients have excess fluid in the peritoneum called ascites. Ascites is a tumour microenvironment (TME) containing various cells, proteins and extracellular vesicles (EVs). We isolated EVs from patients' ascites by orthogonal methods and analyzed them by mass spectrometry. We identified not only a set of 'core ascitic EV-associated proteins' but also defined their subset unique to HGSC ascites. Using single-cell RNA sequencing data, we mapped the origin of HGSC-specific EVs to different types of cells present in ascites. Surprisingly, EVs did not come predominantly from tumour cells but from non-malignant cell types such as macrophages and fibroblasts. Flow cytometry of ascitic cells in combination with analysis of EV protein composition in matched samples showed that analysis of cell type-specific EV markers in HGSC has more substantial prognostic potential than analysis of ascitic cells. To conclude, we provide evidence that proteomic analysis of EVs can define the cellular composition of HGSC TME. This finding opens numerous avenues both for a better understanding of EV's role in tumour promotion/prevention and for improved HGSC diagnostics.

Abstract
The benefits of branched-chain amino acid (BCAA) administration after hepatic intervention in patients with liver diseases remain unclear. We conducted a systematic review and meta-analysis to evaluate the effects of BCAA on patients undergoing hepatectomy, trans-arterial embolisation and radiofrequency ablation. Relevant randomised controlled trials (RCT) were obtained from PubMed, EMBASE and Cochrane Library databases. A meta-analysis was performed to calculate the pooled effect size by using random-effects models. The primary outcomes were survival and tumour recurrence. The secondary outcomes were hospital stay, nutrition status, biochemistry profile, complication rate of liver treatment and adverse effect of BCAA supplementation. In total, eleven RCT involving 750 patients were included. Our meta-analysis showed no significant difference in the rates of tumour recurrence and overall survival between the BCAA and control groups. However, the pooled estimate showed that BCAA supplementation in patients undergoing hepatic intervention significantly increased serum albumin (mean difference (MD): 0·11 g/dl, 95 % CI: 0·02, 0·20; 5 RCT) at 6 months and cholinesterase level (MD: 50·00 U/L, 95 % CI: 21·08, 78·92; 1 RCT) at 12 months and reduced ascites incidence (risk ratio: 0·39, 95 % CI: 0·21, 0·71; 4 RCT) at 12 months compared with the control group. Additionally, BCAA administration significantly increased body weight at 6 months and 12 months and increased arm circumference at 12 months. In conclusion, BCAA supplementation significantly improved the liver function, reduced the incidence of ascites and increased body weight and arm circumference. Thus, BCAA supplementation may beneficial for selected patients undergoing liver intervention.

Abstract
The vasopressin system has emerged as a therapeutic focus for lowering portal hypertension and reducing splanchnic vasodilation in patients with refractory ascites. Clinically available vasopressin agonists are limited by preferential selectivity for V1 receptors that also have steep concentration-response curves with potential risks of excess vasoconstriction and/or complete antidiuretic effects. OCE-205 is a novel, selective, partial V1a receptor agonist with mixed agonist/antagonist activity and no V2 receptor activation at therapeutic doses. We carried out two studies assessing the in vivo effects of OCE-205 in different rat models of cirrhosis and ascites. In a carbon tetrachloride rat cirrhosis model, OCE-205 administration produced a marked reduction in portal hypertension and hyperaldosteronism, along with robust diuretic and natriuretic effects. These effects were accompanied by marked decreases in ascites volume, with three of five animals experiencing total mobilization of ascites. There was no evidence of fluid overload or sodium or water retention, confirming OCE-205's lack of V2 receptor activity. In a second, corroborative study using a bile duct ligation rat model of ascites, OCE-205 produced significant decreases in ascites volume and body weight and a significant increase in urine volume versus vehicle. Urine sodium excretion increased significantly after the first administration of OCE-205 relative to vehicle; however, repeat administration over 5 days did not lead to hyponatremia. Thus, in separate in vivo models, the mixed agonist/antagonist OCE-205 demonstrated relevant and expected endpoint findings consistent with its known mechanism of action and in vitro pharmacology without apparent unwanted effects or nonspecific toxicities.

Abstract
Heavy metals are ubiquitous environmental pollutants that are extremely dangerous for public health, but the molecular mechanisms of their cytotoxic action are still not fully understood. In the present work, the possible contribution of the mitochondrial ATP-sensitive potassium channel (mK(ATP)), which is usually considered protective for the cell, to hepatotoxicity caused by heavy metals was investigated using polarography and swelling techniques as well as flow cytometry. Using isolated liver mitochondria from adult male Wistar rats and various potassium media containing or not containing penetrating anions (KNO3, KSCN, KAcet, KCl), we studied the effect of mK(ATP) modulators, namely its blockers (5-hydroxydecanoate, glibenclamide, ATP, ADP) and activators (diazoxide, malonate), on respiration and/or membrane permeability in the presence of hepatotoxins such as Cd2+, Hg2+, and Cu2+. It has been shown for the first time that, contrary to Hg2+ and depending on media used, the mK(ATP) modulators affect Cd2+- and/or Cu2+-induced alterations in mitochondrial swelling and respiration rates, although differently, nevertheless, in the ways compatible with mK(ATP) participation in both these cases. On rat AS-30D ascites hepatoma cells, it was found that, unlike Cd2+, an increase in the production of reactive oxygen species was observed with the simultaneous use of Cu2+ and diazoxide; in addition, there was no protective effect of diazoxide against cell death, which also occurred in the presence of Cu2+. In conclusion, the relationships (functional, structural and/or regulatory) between mK(ATP), components of the mitochondrial electron transport chain (CI, CII-CIII and/or ATP synthase, CV) and mitochondrial permeability transition pores were discussed, as well as the role of these molecular structures in the mechanisms of the cytotoxic action of heavy metals.

Abstract
AIM To determine whether or not a decoction made from Qigu Zhushui has a suppressive impact on malignant ascites in mice. BACKGROUND Malignant ascites are one of the common complications of advanced malignant tumors. Patients with malignant ascites typically have a poor prognosis, with only 12 to 20 weeks of survival. Currently, the standard treatments for malignant ascites are systemic chemotherapy, which is ineffective in eradicating the disease and is associated with issues such as safety, short duration of sustained high-level drug concentration in localised regions, and drug resistance. OBJECTIVE To clarify the effect of Qigu Zhushui decoction on inhibiting malignant ascites in mice and provide the experimental basis for further research. METHODS The ascites model of liver cancer in mice was established by intraperitoneal injection of the H22-H8D8 cell line of liver cancer. ELISA detected the content of CEA, VEGF and TNF-α in ascites. RESULTS Qigu Zhushui decoction combined with cisplatin group and Qigu Zhushui decoction highdose group could significantly reduce the weight, abdominal circumference and ascites volume of mice, and their survival days and survival rate were also greatly improved; The levels of CEA and VEGF in the combination group decreased significantly, while the level of TNF-α increased; The level of TNF-a in the high dose group of Qigu Zhushui decoction was significantly increased, while the level of CEA and VEGF in the moderate dose group was decreased. CONCLUSION Qigu Zhushui decoction can reduce the malignant ascites in mice, and the combination of Qigu Zhushui decoction and cisplatin has a significant anti-malignant ascites effect, which can significantly prolong the survival time and improve the survival rate.

Abstract
Ovarian cancer (OC) is one of the most common and fatal types of gynecological cancer. In the early phase of OC detection, the current treatment and diagnostic methods are not efficient and sensitive enough. Therefore, it is crucial to explore the mechanisms of OC metastasis and discover valuable factors for early diagnosis of female cancers and novel therapeutic strategies for metastasis. Exosomes are known to be involved in the development, migration, and invasion of cancer cells, and their cargo could be useful for the non-invasive biopsy development. CD151- and Tspan8-positive exosomes are known to support the degradation of the extracellular matrix, and are involved in stroma remodeling, angiogenesis and cell motility, as well as the association of miR-24 and miR-101 with these processes. The objective of this study was to explore the relationship of these components of exosomal cargo, in patients with OC, to clarify the clinical significance of these markers in liquid biopsies. The levels of tetraspanins Tspan8+ and CD151+ exosomes were significantly higher in plasma exosomes of OC patients compared with healthy females (HFs). The relative levels of miR-24 and miR-101 in plasma exosomes of HFs were significantly higher than in plasma exosomes of OC patients, while the levels of these microRNAs in exosomes from plasma and ascites of ill females showed no difference. Our study revealed a strong direct correlation between the change in the ascites exosomes CD151+Tspan8+ subpopulation level and the expression levels of the ascites (R = 0.81, p < 0.05) and plasma exosomal miR-24 (R = 0.74, p < 0.05) in OC patients, which confirms the assumption that exosomal cargo act synergistically to increase cellular motility, affecting cellular processes and signaling. Bioinformatics analysis confirmed the involvement of CD151 and Tspan8 tetraspanins and genes controlled by miR-24-3p and miR-101 in signaling pathways, which are crucial for carcinogenesis, demonstrating that these tetraspanins and microRNAs are potential biomarkers for OC screening, and predictors of poor clinicopathological behavior in tumors.

Abstract
The ascites ecosystem in ovarian cancer is inhabited by complex cell types and is bathed in an environment rich in cytokines, chemokines, and growth factors that directly and indirectly impact metabolism of cancer cells and tumor associated cells. This milieu of malignant ascites, provides a 'rich' environment for the disease to thrive, contributing to every aspect of advanced ovarian cancer, a devastating gynecological cancer with a significant gap in targeted therapeutics. In this perspective we focus our discussions on the 'acellular' constituents of this liquid malignant tumor microenvironment, and how they influence metabolic pathways. Growth factors, chemokines and cytokines are known modulators of metabolism and have been shown to impact nutrient uptake and metabolic flexibility of tumors, yet few studies have explored how their enrichment in malignant ascites of ovarian cancer patients contributes to the metabolic requirements of ascites-resident cells. We focus here on TGF-βs, VEGF and ILs, which are frequently elevated in ovarian cancer ascites and have all been described to have direct or indirect effects on metabolism, often through gene regulation of metabolic enzymes. We summarize what is known, describe gaps in knowledge, and provide examples from other tumor types to infer potential unexplored roles and mechanisms for ovarian cancer. The distribution and variation in acellular ascites components between patients poses both a challenge and opportunity to further understand how the ascites may contribute to disease heterogeneity. The review also highlights opportunities for studies on ascites-derived factors in regulating the ascites metabolic environment that could act as a unique signature in aiding clinical decisions in the future.

This study investigated the anti-ascites effect of the total saponins of Phytolaccae Radix(PRTS) and the mechanism.H22 cell suspension was used(ip) to induce ascites in ICR male mice, and the model mice were randomized into model group, positive drug group(furosemide, 6 mg·kg~(-1)), total extract of Phytolaccae Radix(PRTE) group, and PRTS(1.29 g·kg~(-1)).Another 10 male mice were selected as the blank group.Mice in the blank group and model group were given(ig) normal saline containing 0.5% CMC-Na, and those in the positive drug group, PRTE group, and PRTS group received(ig) corresponding doses of drugs, once a day, for 8 consecutive days.The ascites volume, urine volume, and fecal water content in mice with ascites, serum levels of antidiure-tic hormone(ADH), renin in renin-angiotensin-aldosterone system(RAAS), angiotensin Ⅱ(AngⅡ), and aldosterone(ALD), expression of aquaporin(AQP)1-AQP4 in kidney, expression of AQP1, AQP3 in colon, and expression of phosphatidylinositol 3-kinase/protein kinase B(PI3 K/Akt) pathway-related proteins were detected to explore the anti-ascites mechanism of PRTS.The results showed that the PRTS can increase the urine volume and fecal water content and decrease the ascites volume of ascites mice.Moreover, PRTS significantly reduced the expression of AQP1-AQP4 in kidney and AQP1, AQP3 in colon, serum levels of renin, AngⅡ, ALD, and ADH, and the expression of p-PI3 K and p-Akt in the kidney of ascites mice.PRTS exerts anti-ascites effect by promoting urination and defecation.The mechanism is that it inhibits the activities of RAAS and ADH and suppresses the phosphorylation of PI3 K/Akt signaling pathway, thereby restricting the expression of AQPs in the kidney and colon.

Abstract
Malignant ascites is a common clinical problem in ovarian cancer. NK cells are present in the ascites, but their antitumor activity is inhibited. The underlying mechanisms of the inhibition have yet to be fully elucidated. Using an Fcγ receptor-mediated NK cell activation assay, we show that ascites from ovarian cancer patients potently inhibits NK cell activation. Part of the inhibitory activity is mediated by CA125, a mucin 16 fragment shed from ovarian cancer tumors. Moreover, transcriptional analyses by RNA sequencing reveal upregulation of genes involved in multiple metabolic pathways but downregulation of genes involved in cytotoxicity and signaling pathways in NK cells purified from ovarian cancer patient ascites. Transcription of genes involved in cytotoxicity pathways are also downregulated in NK cells from healthy donors after in vitro treatment with ascites or with a CA125-enriched protein fraction. These results show that ascites and CA125 inhibit antitumor activity of NK cells at transcriptional levels by suppressing expression of genes involved in NK cell activation and cytotoxicity. Our findings shed light on the molecular mechanisms by which ascites inhibits the activity of NK cells and suggest possible approaches to reactivate NK cells for ovarian cancer immunotherapy.

Abstract
Utilizing metabolomics technology, this study explored the change of fecal endogenous metabolites in Walker-256 rats with malignant ascites after the administration with Kansui Radix(KR) stir-fried with vinegar(VKR), sought the potential biomarkers in feces which were related to the treatment of malignant ascites by VKR and revealed the biological mechanism of water-expelling effect of VKR. Ultra-fast liquid chromatography-quadrupole-time-of-flight mass spectrometry(UFLC-Q-TOF-MS) was employed to detect the feces of rats in all groups. Principle component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were conducted to achieve pattern recognition. Combining t-test and variable importance in the projection(VIP) enabled the screening of potential biomarkers for the malignant ascites. Metabolic pathway analysis was accomplished with MetaboAnalyst. Correlation analysis was finally conducted integrating the sequencing data of gut microbiota to elucidate the mechanism underlying the water-expelling effect of VKR. The results showed that both KR and VKR could restore the abnormal metabolism of model rats to some extent, with VKR being inferior to KR in the regulation. Eleven potential biomarkers were identified to be correlated with the malignant ascites and five metabolic pathways were then enriched. Four kinds of gut microbiota were significantly related to the potential biomarkers. The water-expelling effect of VKR may be associated with the regulation of phenylalanine metabolism, biosynthesis of phenylalanine, tyrosine and tryptophan, tryptophan metabolism, glycerophospholipid metabolism, and glycosylphosphatidylinositol(GPI)-anchor biosynthesis. This study can provide a scientific basis for comprehensive understandings of the interaction between gut microbiota and host which has relation to the water-expelling effect of VKR and guide the reasonable clinical application of VKR.

Abstract
In parallel to medical treatment of ovarian cancer, methods for the early detection of cancer tumors are being sought. In this contribution, the use of non-invasive static (SLS) and dynamic light scattering (DLS) for the characterization of extracellular nanoparticles (ENPs) in body fluids of advanced serous ovarian cancer (OC) and benign gynecological pathology (BP) patients is demonstrated and critically evaluated. Samples of plasma and ascites (OC patients) or plasma, peritoneal fluid, and peritoneal washing (BP patients) were analyzed. The hydrodynamic radius (Rh) and the radius of gyration (Rg) of ENPs were calculated from the angular dependency of LS intensity for two ENP subpopulations. Rh and Rg of the predominant ENP population of OC patients were in the range 20–30 nm (diameter 40–60 nm). In thawed samples, larger particles (Rh mostly above 100 nm) were detected as well. The shape parameter ρ of both particle populations was around 1, which is typical for spherical particles with mass concentrated on the rim, as in vesicles. The Rh and Rg of ENPs in BP patients were larger than in OC patients, with ρ ≈ 1.1–2, implying a more elongated/distorted shape. These results show that SLS and DLS are promising methods for the analysis of morphological features of ENPs and have the potential to discriminate between OC and BP patients. However, further development of the methodology is required.

Abstract
The isolation of a patient's metastatic cancer cells is the first, enabling step toward treatment of that patient using modern personalized medicine techniques. Whereas traditional standard-of-care approaches select treatments for cancer patients based on the histological classification of cancerous tissue at the time of diagnosis, personalized medicine techniques leverage molecular and functional analysis of a patient's own cancer cells to select treatments with the highest likelihood of being effective. Unfortunately, the pure populations of cancer cells required for these analyses can be difficult to acquire, given that metastatic cancer cells typically reside in fluid containing many different cell populations. Detection and analyses of cancer cells therefore require separation from these contaminating cells. Conventional cell sorting approaches such as Fluorescence Activated Cell Sorting or Magnetic Activated Cell Sorting rely on the presence of distinct surface markers on cells of interest which may not be known nor exist for cancer applications. In this work, we present a microfluidic platform capable of label-free enrichment of tumor cells from the ascites fluid of ovarian cancer patients. This approach sorts cells based on differences in biomechanical properties, and therefore does not require any labeling or other pre-sort interference with the cells. The method is also useful in the cases when specific surface markers do not exist for cells of interest. In model ovarian cancer cell lines, the method was used to separate invasive subtypes from less invasive subtypes with an enrichment of ~ sixfold. In ascites specimens from ovarian cancer patients, we found the enrichment protocol resulted in an improved purity of P53 mutant cells indicative of the presence of ovarian cancer cells. We believe that this technology could enable the application of personalized medicine based on analysis of liquid biopsy patient specimens, such as ascites from ovarian cancer patients, for quick evaluation of metastatic disease progression and determination of patient-specific treatment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Malignant ascites (MA) effusion is mainly caused by hepatocellular, ovarian, and breast cancer etc. It has been reported that Euphorbia kansui (EK), the root of Euphorbia kansui S.L.Liou ex S.B.Ho, possessing a therapeutic effect on MA. However, the clinical applications of EK are seriously restricted for its severe toxicity. Although studies demonstrated that vinegar-processing can reduce the toxicity and retain the water expelling effect of EK, its specific mechanism remains unknown. AIM OF THE STUDY This study aims to explore the underlying mechanisms of toxicity reduction without compromising the pharmacological effects of EK stir-fried with vinegar (VEK). MATERIALS AND METHODS 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol (3-O-EZ), a major diterpenoid of EK, could convert into ingenol after processing EK with vinegar. The H22 mouse hepatoma ascites model was replicated, and were given 3-O-EZ and ingenol seven days (110.14, 50.07 and 27.54 mg/kg). The histopathological observation, serum liver enzymes, serum Renin-Angiotensin-Aldosterone System (RAAS) levels, ascites volumes, pro-inflammatory cytokines levels and H22 cells apoptosis in ascites were examined. Then the intestine (Aquaporin 8, AQP8) and kidney (Aquaporin 2, AQP2; Vasopressin type 2 receptor, V2R) protein expression were detected, as well as the metabolomics of serum were analyzed. Finally, the content of 3-O-EZ and ingenol in EK and VEK were investigated. RESULTS 3-O-EZ and ingenol can relieve hepatic and gastrointestinal injuries, reduce ascites volumes, enhance the H22 cells apoptosis, ameliorate abnormal pro-inflammatory cytokines and RAAS levels, and down-regulate the expression of AQP8, AQP2, V2R. The involved metabolic pathways mainly included glycerophospholipid metabolism and arachidonic acid metabolism. And the decreasing rate of 3-O-EZ in VEK was 19.14%, the increasing rate of ingenol in VEK was 92.31%. CONCLUSION 3-O-EZ and ingenol possess significant effect in treating MA effusion, while ingenol has lower toxicity compared with 3-O-EZ. And provide evidence for the mechanism of attenuation in toxicity without compromising the pharmacological effects of VEK.

Abstract
The poor prognosis of ovarian cancer is mainly due to metastasis, and the specific mechanism underlying ovarian cancer metastasis is not clear. Ascites-derived exosomes (ADEs) play an important role in the progression of ovarian cancer, but the mechanism is unknown. Here, we found that ADEs promoted ovarian cancer metastasis not only in vitro but also in vivo. This promotive function was based on epithelial-mesenchymal transition (EMT) of ovarian cancer cells. Bioinformatics analysis of RNA sequencing microarray data indicated that miR-6780b-5p may be the key microRNA (miRNA) in ADEs that facilitates cancer metastasis. Moreover, the expression of exosomal miR-6780b-5p correlated with tumor metastasis in ovarian cancer patients. miR-6780b-5p overexpression promoted and miR-6780b-5p downregulation suppressed EMT of ovarian cancer cells. These results suggest that ADEs transfer miR-6780b-5p to ovarian cancer cells, promoting EMT and finally facilitating ovarian cancer metastasis.

Abstract
This study evaluated the anti-ascites effect of total diterpenoids extracted from Euphorbiae ebracteolatae Radix (TDEE) on malignant ascitic mice and elucidated its underlying mechanism. TDEE was extracted by dichloromethane and subjected to column chromatography. The purity of six diterpenoids isolated from TDEE was determined to be 77.18% by HPLC. TDEE (3 and 0.6 g raw herbs/kg, p.o.) reduced ascites and increased urine output. Meanwhile, analysis of tumor cell viability, cycle and apoptosis indicated that TDEE had no antitumor activity. In addition, the expression levels of aquaporins (AQPs) and the membrane translocation levels of protein kinase C (PKC) α and PKCβ in kidney and cells were measured. TDEE reduced the levels of AQP1–4, and inhibited PKCβ expression in membrane fraction. Four main diterpenoids, except compound 2, reduced AQP1 level in human kidney-2 cells. Compounds 4 and 5 inhibited AQP2–4 expression in murine inner medullary collecting duct cells. The diterpenoid-induced inhibition of AQP1–4 expression was blocked by phorbol-12-myristate-13-acetate (PMA; agonist of PKC). The diterpenoids from TDEE are the main anti-ascites components. The anti-ascites effect of diterpenoids may be associated with alterations in AQPs in the kidneys to promote diuresis. The inhibition of AQP1–4 expression by TDEE is related to the inhibition of PKCβ activation.

Abstract
Peritoneal dissemination and malignant ascites in pancreatic ductal adenocarcinoma (PDAC) patients represent a major clinical issue. Lysophosphatidic acid (LPA) is a lipid mediator that modulates the progression of various cancers. Based on the increasing evidence showing that LPA is abundant in malignant ascites, we focused on autotaxin (ATX), which is a secreted enzyme that is important for the production of LPA. This study aimed to elucidate the importance of the ATX-LPA axis in malignant ascites in PDAC and to determine whether ATX works as a molecular target for treating peritoneal dissemination. In a PDAC peritoneal dissemination mouse model, the amount of ATX was significantly higher in ascites than in serum. An in vitro study using two PDAC cell lines, AsPC-1 and PANC-1, showed that ATX-LPA signaling promoted cancer cell migration via the activation of the downstream signaling, and this increased cell migration was suppressed by an ATX inhibitor, PF-8380. An in vivo study showed that PF-8380 suppressed peritoneal dissemination and decreased malignant ascites, and these results were validated by the biological analysis as well as the in vitro study. Moreover, there was a positive correlation between the amount of ATX in ascites and the degree of disseminated cancer progression. These findings demonstrated that ATX in ascites works as a promotor of peritoneal dissemination, and the targeting of ATX must represent a useful and novel therapy for peritoneal dissemination of PDAC.

Abstract
The presence of ascites in the peritoneal cavity leads to morphological and functional changes of the peritoneal mesothelial cell layer. Cells loose cell-cell interactions, rearrange their cytoskeleton, activate the production of fibronectin, and change their cell surface morphology in a proinflammatory environment. Moreover, ovarian cancer cell adhesion has been shown to be facilitated by these changes due to increased integrin- and CD44-mediated binding sites. In this study, the biological responsiveness of the human pleural mesothelial cell line MeT-5A to patient-derived and artificial ascites was studied in vitro and adhesion of ovarian cancer cells, i.e. SKOV-3 cells, investigated. Changes were mainly observed in cells exposed to artificial ascites containing higher cytokine concentrations than patient-derived ascites. Interestingly, reduced cell-cell interactions were already observed in untreated MeT-5A cells and effects on tight junction protein expression and permeability upon exposure to ascites were minor. Ascites induced upregulation of CDC42 effector protein 2 expression, which affects stress fiber formation, however significant F-actin reorganization was not observed. Moreover, fibronectin production remained unchanged. Analysis of mesothelial cell surface characteristics showed upregulated expression of intercellular adhesion molecule 1, slightly increased hyaluronic acid secretion and decreased microvillus expression upon exposure to ascites. Nevertheless, the observed changes were not sufficient to facilitate adhesion of SKOV-3 cells on MeT-5A cell layer. This study revealed that MeT-5A cells show a reduced biological responsiveness to the presence of ascites, in contrast to published studies on primary human peritoneal mesothelial cells.

Abstract
Hyponatremia is frequently seen in patients with ascites secondary to advanced cirrhosis and portal hypertension. Although not apparent in the early stages of cirrhosis, the progression of cirrhosis and portal hypertension leads to splanchnic vasodilation, and this leads to the activation of compensatory mechanisms such as renin-angiotensin-aldosterone system (RAAS), sympathetic nervous system, and antidiuretic hormone (ADH) to ameliorate low circulatory volume. The net effect is the avid retention of sodium and water to compensate for the low effective circulatory volume, resulting in the development of ascites. These compensatory mechanisms lead to impairment of the kidneys to eliminate solute-free water in decompensated cirrhosis. Nonosmotic secretion of antidiuretic hormone (ADH), also known as arginine vasopressin, further worsens excess water retention and thereby hyponatremia. The management of hyponatremia in this setting is a challenge as conventional therapies for hyponatremia including fluid restriction and correction of hypokalemia are frequently inefficacious. In this review, we discuss the pathophysiology, complications, and various treatment modalities, including albumin infusion, selective vasopressin receptor antagonists, or hypertonic saline for patients with severe hyponatremia and those awaiting liver transplantation.

Abstract
N 6-Methyladenosine (m6A) is the most abundant modification of mammalian mRNAs. RNA methylation fine tunes RNA stability and translation, altering cell fate. The fat mass- and obesity-associated protein (FTO) is an m6A demethylase with oncogenic properties in leukemia. Here, we show that FTO expression is suppressed in ovarian tumors and cancer stem cells (CSC). FTO inhibited the self-renewal of ovarian CSC and suppressed tumorigenesis in vivo, both of which required FTO demethylase activity. Integrative RNA sequencing and m6A mapping analysis revealed significant transcriptomic changes associated with FTO overexpression and m6A loss involving stem cell signaling, RNA transcription, and mRNA splicing pathways. By reducing m6A levels at the 3'UTR and the mRNA stability of two phosphodiesterase genes (PDE1C and PDE4B), FTO augmented second messenger 3', 5'-cyclic adenosine monophosphate (cAMP) signaling and suppressed stemness features of ovarian cancer cells. Our results reveal a previously unappreciated tumor suppressor function of FTO in ovarian CSC mediated through inhibition of cAMP signaling. SIGNIFICANCE: A new tumor suppressor function of the RNA demethylase FTO implicates m6A RNA modifications in the regulation of cyclic AMP signaling involved in stemness and tumor initiation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euphorbia kansui is a toxic Chinese herbal medicine and exhibits promising treatment to the malignant ascites (MA) in its traditional use. Ingenane-type and jastrophane-type diterpenes are demonstrated to be responsible for the toxicity and efficacy of kansui. Two representative compounds, kansuiphorin C (KPC) and kansuinin A (KA) in each type were proved to effectively reduce the ascites. The biological and toxicological effects are closely associated with the gastrointestinal tract, but the possible mechanism and related metabolic functions of KPC and KA treating MA through modulating the gut microbiota remain unclear. AIM OF THE STUDY To investigate the possible mechanism and related metabolism of KPC and KA ameliorating malignant ascites through modulating gut microbiota. MATERIALS AND METHODS MA rats and normal rats were divided into different groups and administrated with KPC, KA, and positive drug, respectively. 16S rDNA gene sequencing and metagenomes analysis combined with the quantification of short-chain fatty acids of feces were performed to reflect the modulation of gut microbiota. Then, the metabolites of KPC and KA in rat feces under the normal and pathological circumstances were detected by ultra-fast liquid chromatography coupled with MS/MS detector (UFLC-MS/MS) to explore the in-vivo bacterial biotransformation. RESULTS KPC and KA were modulatory compounds for gut microbiota. The richness of Lactobacillus and the decreased abundance of Helicobacter involved in the carbohydrate metabolism and amino acid metabolism could be responsible for their prohibitory effects on malignant ascites. KPC exhibited stronger modulation of gut microbiota through making the abundance of Helicobacter about 3.5 times lower than KA. Besides, in-vivo microbial biotransformation of KPC and KA contained oxidation, hydrolysis, dehydration, and methylation to form metabolites of lower polarity. Besides, at the dosage of 10 mg kg-1, the toxicity of both compounds had weaker influences on the gut microbiota of normal rats. CONCLUSION KPC and KA could ameliorate malignant ascites by modulating gut microbiota mainly containing the increase of Lactobacillus and the decrease of Helicobacter and related carbohydrate and amino acid metabolism, providing a basis for their promising clinical usage.

Abstract
ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, increases the intracellular levels of glutathione (GSH) by upregulating solute carrier family 7 member 11 (SLC7A11). Diffuse-type gastric cancer is an aggressive tumor that is frequently associated with ARID1A deficiency. Here, we investigated the efficacy of GSH inhibition for the treatment of diffuse-type gastric cancer with ARID1A deficiency using ARID1A-proficient or -deficient patient-derived cells (PDCs). ARID1A-deficient PDCs were selectively sensitive to the GSH inhibitor APR-246, the GCLC inhibitor buthionine sulfoximine, and the SLC7A11 inhibitor erastin. Expression of SLC7A11, which is required for incorporation of cystine, and the basal level of GSH were lower in ARID1A-deficient than in ARID1A-proficient PDCs. Treatment with APR-246 decreased intracellular GSH levels, leading to the excessive production of reactive oxygen species (ROS), and these phenotypes are suppressed by supply of cystine and GSH compensators. Taken together, vulnerability of ARID1A-deficient gastric cancer cells to GSH inhibition is caused by decreased GSH synthesis due to diminished SLC7A11 expression. The present results suggest that GSH inhibition is a promising strategy for the treatment of diffuse-type gastric cancers with ARID1A deficiency.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine boasts a 440-year-long history of treating refractory ascites via combinations of herbal medicines, called formulae. Xiaozhang Tie (XT) is a proprietary herbal-compound-based formula that has been proven to be very effective in the treatment of cirrhosis-associated ascites in clinical practice, but the mechanism of action of XT remains unknown. AIM OF THE STUDY In this study, we used a metabolomics-based systematic method to elucidate the mechanism of XT in the treatment of cirrhotic ascites. METHODS Decompensated liver cirrhosis was induced in rats by intraperitoneal injection of Carbon tetrachloride (CCl4). Ultra performance liquid chromatography-mass spectrometry (UPLC-MS) combined with pattern recognition approaches were used to determine differentiating metabolites relevant to XT treatment. Biomarkers were further validated by a targeted quantitative method and by the results from serum and urine analyses. Pathway analysis and correlation network construction were used to reveal the therapeutic targets associated with XT treatment, and the potential mechanisms were verified by the results from biochemical, histopathological and immunohistochemical assays. RESULTS XT synergistically mediated the abnormalities of amino acid metabolic pathways in cirrhotic rats. XT significantly elevated the arginine levels, reduced the serum nitric oxide (NO) levels and alleviated the gastrointestinal motility disorder of cirrhotic rats. This effect of XT has been confirmed by the inhibition of the activities of inducible NO synthase and neuronal NO synthase in the small intestine. CONCLUSIONS These results reveal that XT promotes gastrointestinal motility by acting on multiple targets in multiple pathways, of which the L-arginine/NO pathway is most affected.

Abstract
Spontaneous bacterial peritonitis (SBP) is one of the most frequent and severe complications in patients with decompensated cirrhosis. Early antibiotic therapy is extremely important for successful treatment and reducing mortality. Prostaglandin E2 (PGE2) is a regulator of the immune response and infection. This study aimed to explore whether ascitic PGE2 could be used as a marker for diagnosing SBP and predicting in-hospital mortality.Patients with cirrhosis and ascites undergoing abdominal paracentesis were enrolled in our study. Demographic, clinical, and laboratory parameters were recorded at the time of paracentesis and ascitic PGE2 levels were determined by ELISA. The correlation between ascitic PGE2 level and SBP as well as in-hospital mortality were analyzed.There were 224 patients enrolled, 29 (13%) patients diagnosed as SBP based on the current guideline criteria. The ascitic PGE2 level of patients with SBP [32.77 (26.5-39.68) pg/mL] was significantly lower than that of patients without SBP [49.72 (37.35-54.72) pg/mL]. In ROC analysis, the AUC of ascitic PGE2 for the diagnosis of SBP was 0.75, and the AUC of ascitic PGE2 combined with WBC and ascitic PGE2 combined with neutrophils were 0.90 and 0.90, respectively, which were significantly higher than that of ascitic PGE2. In multivariate analysis, ascites PGE2≤32.88 pg/mL (OR: 9.39; 95% CI: 1.41-67.44, P = .026), hepatic encephalopathy (OR: 18.39; 95% CI: 3.00-113.13, P = .002) and a higher MELD score (OR: 1.25; 95% CI: 1.05-1.40, P = .009) remained independent predictors of in-hospital mortality.Ascitic PGE2 level is likely to be a valuable marker in prediction of in-hospital mortality in patients with decompensated cirrhosis, and its value in diagnosis of SBP was not superior to other inflammatory indicators.

Abstract
Background Peritoneal tuberculosis (TB) remains difficult to diagnose because of its non-specific clinical features and the lack of efficient microbiological tests. As delayed diagnosis is associated with high mortality rates, new diagnostic tools are needed. Methods and findings We investigated for 24 patients prospectively enrolled with a possible diagnosis of peritoneal TB, the diagnostic value of the analysis of IFN-γ production by peritoneal fluid lymphocytes in response to a short in vitro stimulation with mycobacterial antigens. The patients were classified in two groups: non-TB and confirmed or highly probable TB. Diagnosis of TB was based on microbiological and histopathological criteria and/or a favorable response to anti-TB treatment. The IFN-γ production by peritoneal CD4+ T lymphocytes was analyzed by flow cytometry after an overnight in vitro stimulation with three different mycobacterial antigens, purified protein derivative (PPD), heparin-binding haemagglutinin (HBHA) or early-secreted-antigen-target-6 (ESAT-6). The percentages of PPD-, HBHA- or ESAT-6-induced IFN-γ-producing peritoneal fluid CD4+ T lymphocytes were higher in the TB group than in the non-TB group (p = 0.0007, p = 0.0004, and p = 0.0002 respectively). Based on cut-off values determined by ROC curve analysis of the results from TB and highly probable TB compared to those of non-TB patients, the sensitivity of these three tests was 100% with a specificity of 92%. Conclusions The analysis of mycobacterial-induced IFN-γ production by peritoneal lymphocytes is a promising tool to reliably and rapidly diagnose peritoneal TB. Further studies should be performed on larger cohorts of patients in high-TB-incidence countries to confirm the clinical value of this new diagnostic approach for peritoneal TB.

Abstract
Ascitic fluid infection is a major cause of morbidity and mortality in cirrhotic patients, requiring early diagnosis and therapy. We aimed to determine predictors of ascitic fluid infection in children with chronic liver disease. The study included 45 children with chronic liver disease and ascites who underwent 66 paracentesis procedures. Full history taking and clinical examination of all patients were obtained including fever, abdominal pain and tenderness and respiratory distress. Investigations included: complete blood count, C-reactive protein, full liver function tests, ascitic fluid biochemical analysis, cell count and culture. Our results showed that patients' ages ranged between 3 months to 12 years. Prevalence of ascitic fluid infection was 33.3%. Gram-positive bacteria were identified in six cases, and Gram-negative bacteria in five. Fever and abdominal pain were significantly more associated with infected ascites (p value = 0.004, 0.006). Patients with ascitic fluid infection had statistically significant elevated absolute neutrophilic count and C-reactive protein. Logistic regression analysis showed that fever, abdominal pain, elevated absolute neutrophilic count and positive C-reactive protein are independent predictors of ascitic fluid infection. Fever, elevated absolute neutrophilic count and positive C-reactive protein raise the probability of ascitic fluid infection by 3.88, 9.15 and 4.48 times respectively. The cut-off value for C-reactive protein for ascitic fluid infection was 7.2 with sensitivity 73% and specificity of 71%. In conclusion, prevalence of ascitic fluid infection in pediatric patients with chronic liver disease and ascites was 33.3%. Fever, abdominal pain, positive C-reactive protein and elevated absolute neutrophilic count are strong predictors of ascitic fluid infection. Therefore an empirical course of first-line antibiotics should be immediately started with presence of any of these predictors after performing ascitic fluid tapping for culture and sensitivity. In absence of these infection parameters, routine ascitic fluid analysis could be spared.

Abstract
Background/aim Our study aimed to investigate a reliable diagnostic approach for tuberculous peritonitis (TBP) by comparing the
commonly used diagnostic tools. Materials and methods Fifty-one patients had received a series of diagnoses, including laparoscopy, erythrocyte sedimentation rate
(ESR), cancer antigen 125 (CA125), tuberculin skin test, tuberculosis antibody in serum (TB-Ab), the T-SPOT.TB test, or adenosine
deaminase (ADA) in ascitic fluid. The positive rate of each method was calculated and the differences of positive rates between
laparoscopy and laboratory tests that had higher positive rates were analyzed by McNemar chi-square test. Results The most common symptoms and signs of 51 patients were fever (86.3%), abdominal mass (78.4%), abdominal distension
(62.7%), abdominal pain (74.5%), and weight loss (66.7%). Furthermore, the positive rates of CA125, laparoscopy, T-SPOT.TB test, and
ESR were relatively higher than those of the other three methods (tuberculin skin test, TB-Ab, and ascitic ADA). Additionally, there was
no significant difference (P > 0.05) in the positive rates between the diagnoses of laparoscopy and those three laboratory tests. Conclusion CA125, laparoscopy, T-SPOT.TB test, and ESR had a stronger diagnostic power for TBP, and they are reliable alternatives
for the diagnosis of TBP.

Abstract
This study was conducted to develop a novel algorithm for determining the origin of tumors by combining analysis of cluster patterns with immunocytochemistry (ICC) for markers in cells from fine-needle aspirates of ascites. We used LBC, based on SurePathTM (BD Diagnostics) technology, to screen 96 peritoneal fluid samples from patients with known malignancies and from 10 control patients with cirrhosis. Following dual ICC staining for cytokeratin 7 (CK7) and paired box gene 8 (PAX8), we developed an algorithm using immunoreactivity and three-dimensional (3D) cluster patterns to correlate staining and 3D cluster patterns with common primary origins that included stomach, ovarian, pancreatobiliary tract, colon, lung, and breast cancers. With the application of an automatic digitalized image analyzer, competence performance was analyzed using receiver operating characteristics (ROC) curve analysis. CK7 and PAX8 staining and 3D cluster patterns were used to differentiate primary origins. Samples from patients with stomach cancer were no 3D cluster /CK7+/PAX8- with area under the curve (AUC) of 0.8699 in ROC curve analysis. Samples from ovarian cancer patients were large 3D cluster/CK7+/PAX8+ with AUC of 0.9812. Samples from pancreatobiliary tract cancer patients were small 3D cluster/CK7+/PAX8- with AUC of 0.8772. The remaining cancer samples, including breast, lung and colon cancer samples, had similar patterns of large 3D clusters/CK7+/PAX8- with AUC of 0.882, especially for lung cancer. SurePathTM technology, using 3D cluster patterns and dual ICC for CK7 and PAX8 in peritoneal fluid samples, can provide important information for determining specific primary origins in cases of unknown primary carcinoma.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kansui, the root of Euphorbia kansui S.L.Liou ex S.B.Ho (E.kansui), is a classical traditional Chinese medicine (TCM) with certain toxicity. According to the theory of TCM, kansui fry-baked wtith vinegar (VEK) possesses low toxicity and mild diuretic and purgative efficacy. In clinical practice, it is commonly used for the treatmtablent of ascites and oliguria. The present study aimed to evaluate the toxicity and efficacy of different fractions of VEK and reveal the underlying material basis by employing an animal model of malignant ascites effusion (MAE) in rats. MATERIALS AND METHODSTA The MAE rats as the model were constructed in SPF male wistar rats by intraperitoneal injection of Walker-256 tumor cells. The MAE rats were used and randomly divided into the control group (normal rats), control groups with different fractions (VEKA, VEKB, VEKC and VEKD), model group (MAE rats), positive control group (model group with furosemide), model groups with different fractions (VEKA, VEKB, VEKC and VEKD). Histopathological observation was used to confirm Walker-256 tumor-bearing organ injuries in rats. For the efficacy evaluation, the ascites and urine volumes, the urinary electrolyte concentrations (Na+, K+ and Cl-) and pH, the ascites levels of pro-inflammatory cytokines (IL-2, IL-6, TNF-α, IFN-γ and VEGF), PRA, the serum levels of Ang II, ALD and ADH, as well as AQP8 protein expression in the gastrointestinal tract were detected. Furthermore, different levels of indicators were measured in the toxicity evaluation of different fractions both on normal and model rats, including serum liver enzymes (AST and ALT), serum oxidative damage parameters (GSH, MDA, LDH and SOD), expressions of inflammatory parameters (NF-κB, ICAM-1 and E-cadherin) and apoptosis signals (caspase-3, -8, -9, Bcl-2 and Bax) in the liver and gastrointestinal tract. RESULTS Walker-256 tumor-bearing malignant ascites effusion rats showed obvious hepatic and gastrointestinal injuries by histopathological observation. In the efficacy evaluation, model rats treated with VEKB and VEKC showed significant urine increase (VEKB, P < 0.01; VEKC, P < 0.01) and ascites reduction (VEKB, P < 0.01; VEKC, P < 0.01). These two fractions also balanced the concentrations of Na+, K+ and Cl- in urine (VEKB, all P < 0.05; VEKC, all P < 0.05), remarkably decreased urinary pH (VEKB, P < 0.01; VEKC, P < 0.01), and reduced the ascites levels of IL-2, IL-6, TNF-α, IFN-γ and VEGF (VEKB, all P < 0.01; VEKC, all P < 0.01) in the model rats. Moreover, levels of PRA, the serum Ang II, ALD and ADH of model rats were decreased after treated by VEKB and VEKC (VEKB, all P < 0.05; VEKC, all P < 0.05). Meanwhile, the expression of gastrointestinal AQP8 of the model rats was also enhanced after treated by VEKB and VEKC (VEKB, P < 0.01; VEKC, P < 0.01). In the toxicity evaluation, although VEKB and VEKC caused toxic indexes moved to the worse aspects in normal rats, nearly all of these indicators notably improved in the model rats. Additionally, VEKA showed no effect on the indicators, either in the efficacy evaluation or in the toxicity evaluation. And VEKD could significantly improve some indicators (urine volume, concentration of K+ in urine, serum MDA, AI and caspase-9) in MAE rats. CONCLUSIONS VEKB and VEKC were demonstrated a significant efficacy in treating malignant ascites effusion, which could reduce hepatic and gastrointestinal damage on the model rats but cause the same damage to the normal. These data embody the traditional Chinese medicine application principle: You Gu Wu Yun. And these results will provide reference for the safer and better clinical utilization of kansui.

Abstract
Background: Primary cytoreduction surgery followed by chemotherapy is the cornerstone treatment for epithelial ovarian cancer (EOC). In patients with a low probability of optimal primary surgical debulking, neoadjuvant chemotherapy (NACT) followed by interval debulking increases the chance of optimal surgery. The aim of this study was to develop a model to identify preoperative predictors for suboptimal cytoreduction. Methods: Medical records of patients with EOC who underwent primary cytoreductive surgery in a referral tertiary gyneco-oncology center were reviewed from 2007 to 2017. Data were collected on a range of characteristics including demographic features, comorbidities, serum tumor markers, hematologic markers, preoperative imaging, surgical procedures, and pathologic reports. Univariate and multivariate analyses were performed to clarify the ability of preoperative factors to predict suboptimal primary surgery. Results: The majority of patients (71.3%) who underwent primary cytoreductive surgery were optimally debulked. Based on the Youden index, the best cut-off point for the serum CA125 level to distinguish suboptimal debulking was 420U/ml with 0.730 (95%CI:0.559 to 0.862) sensitivity and 0.783 (0.684 to 0.862) specificity. Multiple logistic regression results showed that serum CA125 level >420 U/ ml (p value <0.001), the presence of liver metastasis on preoperative imaging (p value: 0.041) and ascites (p value: 0.032) or massive ascites (p value:0.010) significantly increased the risk of suboptimal debulking (logit p = 2.36 CA125 level +1.85 Liverinvolvement +1.68 presence of Ascites+ 2.28 Massive Ascites). Conclusion:The present study suggests that a serum CA125 level >420 U/ml, the presence of ascites or massive ascites and liver metastasis are strong predictors of suboptimal primary surgery in cases of EOC. Based on the constructed model, with any of these 4 factors, the probability of suboptimal debulking in EOC is more than 80%.

Abstract
The primary objective of the treatment of malignant ascites in advanced stages is to alleviate symptoms using procedures such as diuresis, paracentesis of subretinal fluid and vena cava anastomosis. The effectiveness of systemic or intraperitoneal chemotherapy treatment is limited, and more efficacious therapies are required. The authors of the present study demonstrated that an antimicrobial peptide, cecropinXJ, isolated from the larvae of Bombyx mori, selectively inhibits the proliferation of gastric cancer cells. However, the effects of antibacterial peptides on gastric ascites tumor remains unclear. In the present study, the therapeutic effects of cecropinXJ were investigated in mice bearing malignant ascites. Compared with bovine serum albumin treatment, cecropinXJ and doxorubicin (Dox) significantly inhibited the formation and growth of malignant ascites, and prolonged the survival time of ascites tumor‑bearing mice. In addition, cecropinXJ treatment normalized the hematological and biochemical phenotypes, induced tumor cell apoptosis in ascites and improved the survival of mice bearing malignant ascites when compared with Dox treatment. These results suggested that cecropinXJ might be a promising therapeutic candidate for the treatment of gastric cancer‑associated ascites.

Abstract
The distribution of hematoporphyrin was determined in normal rats and in rats bearing ascites hepatoma as a function of time after i.p. injection of 10-20 mg/kg of dye. In both cases, hematoporphyrin displayed a high affinity for the tumor cells. At 20 mg/kg, the maximum difference between the amount of hematoporphyrin accumulated in the tumor and in the liver was obtained at 12 h after injection (tumor/liver ratio = 28). Our results suggest that hematoporphyrin is almost exclusively metabolized in the liver and excreted via the biliary tract, whereas only minor amounts are metabolized in the tumor cells. Moreover, the binding between the porphyrin and tumor cells is competitive with serum protein binding.

Abstract
Ovarian cancer (OC) is the leading cause of gynecological cancer-related death in North America. Most ovarian cancer patients (OCPs) experience disease recurrence after first-line surgery and chemotherapy; thus, there is a need for novel second-line treatments to improve the prognosis of OC. Although peripheral blood-derived NK cells are known for their ability to spontaneously lyse tumour cells without prior sensitization, ascites-derived NK cells (ascites-NK cells) isolated from OCPs exhibit inhibitory phenotypes, impaired cytotoxicity and may play a pro-tumourigenic role in cancer progression. Therefore, it is of interest to improve the cytotoxic effector function of impaired OCP ascites-NK cells at the tumour environment. We investigated the efficacy of using an artificial APC-based ex vivo expansion technique to generate cytotoxic, expanded NK cells from previously impaired OCP ascites-NK cells, for use in an autologous model of NK cell immunotherapy. We are the first to obtain a log-scale expansion of OCP ascites-NK cells that upregulate the surface expression of activating receptors NKG2D, NKp30, NKp44, produce robust amounts of anti-tumour cytokines in the presence of OC cells and mediate direct tumour cytotoxicity against ascites-derived, primary OC cells obtained from autologous patients. Our findings demonstrate that it is possible to generate cytotoxic OCP ascites-NK cells from previously impaired OCP ascites-NK cells, which presents a promising immunotherapeutic target for the second-line treatment of OC. Future work should focus on evaluating the in vivo efficacy of autologous NK cell immunotherapy through the intraperitoneal delivery of NK cell expansion factors to a preclinical xenograft mouse model of human OC.

Abstract
The levels of soluble interleukin-2 receptors (sIL-R2) were measured in the serum of 52 patients with epithelial ovarian carcinoma as well as in 25 age and sex-matched normal controls. The mean serum level of sIL-2R was increased in 37 patients (71.2%). Comparison of these levels to those of normal controls showed a highly statistically significant difference (p<0.001). Serum sIL-2R levels were not related to histology, clinical stage or the presence of ascites (p-0.58, p=0.32 and p=0.67, respectively), nor did they follow disease activity or response to chemotherapy. However, patients with higher pretreatment sIL-2R levels (more than 1200 U/ml) were found to have a longer survival (p<0.02), possibly explained by the presence of activated lymphocytes and a better immune surveillance. We conclude that the serum level of sIL-2R: a) is elevated in ovarian cancer patients, b) has no relationship with histological subtypes, tumor burden or the presence of ascites, c) cannot serve as a valuable tumor marker for the monitoring of patient treatment, and d) has a prognostic value for survival.

Abstract
Ascites is a rare complication of multiple myeloma (MM); in most cases, the direct invasion of myeloma cells to the peritoneal cavity has been assumed to be the etiology because the effusion is usually exudative and contains a high proportion of myeloma cells. We herein report a case of MM with massive ascites containing only a small amount of myeloma cells. Instead, high levels of serum and ascitic vascular endothelial growth factor were detected. This was suggested to be a potential mechanism underlying the development of ascites.

Abstract
It has not been systematically analyzed whether the NADPH supply is a limiting factor for oxidative stress management in cancer cells. In the present work, it was determined in non-cancer and cancer cells the protein contents and kinetomics of (i) the cytosolic enzymes responsible for the NADPH production (i.e., Glc6PDH, 6PGDH, ME, IDH-1); and (ii) the two main enzymes responsible for NADPH/NADP+ and GSH/GSSG recycling (GR, GPx-1) associated to oxidative stress management. With these data, kinetic models were built and further validated. Rat liver and hepatoma AS-30D cytosolic fractions exhibited greater Vmax for IDH-1 than for Glc6PDH and 6PGDH whereas human cancer cells and platelets showed greater Vmax for Glc6PDH than for 6PGDH and IDH-1. The ME activity was comparatively low in all cell types tested. The Km values for the respective specific substrates were all similar among the different cell types. Most activities were lower in AS-30D cells than in liver. In contrast, IDH-1, Glc6PDH and GR activities in human cancer cells were similar or greater to those of platelets, but GPx-1 activity was severely suppressed, despite showing similar GPx-1 protein content vs. platelets. Kinetic analysis and pathway modeling revealed a previously unveiled feedback IDH-1 regulation by GSH. The oxidative stress management in cancer cells (i) was mainly controlled by GPx-1 and the main NADPH provider was Glc6PDH; and (ii) modeling indicated that NADPH supply was not a controlling step. These data suggested that Glc6PDH and GPx-1 are adequate and promising targets for anti-cancer therapeutic intervention.

Abstract
Ovarian cancer (OC) is the fifth cancer death cause in women worldwide. The malignant nature of this disease stems from its unique dissemination pattern. Epithelial-to-mesenchymal transition (EMT) has been reported in OC and downregulation of Epithelial cadherin (E-cadherin) is a hallmark of this process. However, findings on the relationship between E-cadherin levels and OC progression, dissemination and aggressiveness are controversial. In this study, the evaluation of E-cadherin expression in an OC tissue microarray revealed its prognostic value to discriminate between advanced- and early-stage tumors, as well as serous tumors from other histologies. Moreover, E-cadherin, Neural cadherin (N-cadherin), cytokeratins and vimentin expression was assessed in TOV-112, SKOV-3, OAW-42 and OV-90 OC cell lines grown in monolayers and under anchorage-independent conditions to mimic ovarian tumor cell dissemination, and results were associated with cell aggressiveness. According to these EMT-related markers, cell lines were classified as mesenchymal (M; TOV-112), intermediate mesenchymal (IM; SKOV-3), intermediate epithelial (IE; OAW-42) and epithelial (E; OV-90). M- and IM-cells depicted the highest migration capacity when grown in monolayers, and aggregates derived from M- and IM-cell lines showed lower cell death, higher adhesion to extracellular matrices and higher invasion capacity than E- and IE-aggregates. The analysis of E-cadherin, N-cadherin, cytokeratin 19 and vimentin mRNA levels in 20 advanced-stage high-grade serous human OC ascites showed an IM phenotype in all cases, characterized by higher proportions of N- to E-cadherin and vimentin to cytokeratin 19. In particular, higher E-cadherin mRNA levels were associated with cancer antigen 125 levels more than 500 U/mL and platinum-free intervals less than 6 months. Altogether, E-cadherin expression levels were found relevant for the assessment of OC progression and aggressiveness.

Abstract
Dendritic cells (DC) have the potential to instigate a tumour-specific immune response, but their ability to prime naïve lymphocytes depends on their activation status. Thus, for tumour immunotherapy to be effective, the provision of appropriate DC activation stimuli such as Toll-like receptor (TLR) agonists is crucial in order to overcome immunosuppression associated with the tumour microenvironment. To address this, we investigated how ovarian carcinoma (OC)-associated ascites impedes activation of DC by TLR agonists. Our results show that ascites reduces the TLR-mediated up-regulation of CD86 and partially inhibits the production of the pro-inflammatory cytokines interleukin 6 (IL-6), IL-12 and tumour necrosis factor α (TNFα) in monocyte-derived DC from healthy controls. We further observe an impaired T cell stimulatory capacity of DC upon activation with TLR agonists in the presence of ascites, indicating that their functionality is affected by the immunosuppressive factors. We identify IL-10 and prostaglandin E2 (PGE2) as the pivotal immunosuppressive components in OC-associated ascites compromising TLR-mediated DC activation. Interestingly, IL-10 is present in both ascites from patients with malignant OC and in peritoneal fluid from patients with benign ovarian conditions and both fluids have similar ability to reduce TLR-mediated DC activation. However, depletion of IL-10 from ascites revealed that the presence of paracrine IL-10 is not crucial for ascites-mediated suppression of DC activation in response to TLR activation. Unlike IL-10, PGE2 is absent from peritoneal fluid of patients with benign conditions and selectively reduces TNFα induction in response to TLR-mediated activation in the presence of OC-associated ascites. Our study highlights PGE2 as an immunosuppressive component of the malignant OC microenvironment rendering PGE2 a potentially important target for immunotherapy in OC.

Abstract
BACKGROUND Ascitic fluids of horses and humans have fibrinolytic activity, independent of the underlying mechanism of fluid formation. OBJECTIVE To determine whether coagulation and fibrinogenolytic/fibrinolytic activity (ie, low fibrinogen and increased fibrin-fibrinogen degradation products [FDPs], D-dimer, or both) occur in all types of ascitic fluid in dogs. ANIMALS A total of 70 client-owned dogs with ascites. METHODS In this cross-sectional study, dogs were categorized based on the pathophysiology of fluid formation into 4 groups: transudates due to decreased osmotic pressure, transudates due to increased hydrostatic pressure, exudates, and hemorrhagic ascites. Fibrinogen, FDPs, and D-dimer concentrations were measured and then compared in both ascitic fluid and plasma. RESULTS Ten dogs had transudates due to decreased colloid osmotic pressure, 18 had transudates due to increased hydrostatic pressure, 13 had exudates, and 29 had hemorrhagic ascites. Ascitic fibrinogen concentrations (n = 70) were significantly lower (median = 59 mg/dL; range: 59-122 mg/dL) than those in the plasma (median = 168 mg/dL, range: 59-879 mg/dL; P < .0001). Ascitic FDPs concentrations (n = 70) were significantly higher (<5 μg/mL: 3/70 dogs, ≥5 to <20 μg/mL: 11/70 dogs, ≥20 μg/mL: 56/70 dogs) than those in the plasma (<5 μg/mL: 17/70 dogs, ≥5 to <20 μg/mL: 28/70 dogs, ≥20 μg/mL: 25/70 dogs; P < .0001). Ascitic D-dimer concentrations (n = 70) were significantly higher (median = 3.98 μg/mL, range: 0.02-9.19) than those in the plasma (median = 0.11 μg/mL, range: 0.01-4.08; P < .0001). Analysis of the data for each of the 4 different types of ascites showed similar results to those of all the data analyzed together. CONCLUSIONS AND CLINICAL IMPORTANCE Ascitic fluid of dogs has evidence of coagulation activation and fibrinogenolytic/fibrinolytic activity and that this phenomenon occurs independent of the underlying mechanism that leads to the formation of ascites.

Abstract
BACKGROUND Ovarian cancer is the most lethal gynecological cancer, almost 80% of all patients succumb the disease within 5 years of diagnosis. High mortality is caused especially by nonspecific symptoms, diagnosis in late stages and the absence of a specific biomarker. Currently, the most common diagnostic biomarkers are the membrane glycoprotein Cancer Antigen 125 (CA 125), the Human Epididymal Protein 4 (HE4) and the Carcinoembryonic Antigen (CAE). None of these biomarkers is specific only for ovarian cancer and increased levels may be caused by other diseases. Therefore, current research is focused on finding new biomarkers for diagnosis and prognosis of ovarian cancer. Interesting clinical material is ascites, the fluid accumulated in abdominal cavity, which is typical for ovarian cancer and it is present in almost 90% of all cases of stage III and IV. MATERIAL AND METHODS For this study, samples of ascites from patients with benign and malignant ovarian tumors were used. For full glycomic and proteomic analysis, only 5 µL of ascites were used. Glycans were released from proteins by the enzyme PNGase F and proteins were digested to peptides by trypsin. Samples were purified and measured using a mass spectrometer. RESULTS Glycan and protein profiles of patients with benign and malignant ovarian cancer were compared. In patient with a benign tumor, more simple glycans with lowm/z were increased while in the patient with a malignant tumor, higher, more complex glycans were increased. In the malignat tumor in comparison to benign tumor, 127 unique proteins were identified, especially proteins of the annexin, mucin and peroxiredoxin families. CONCLUSION This investigation is a pilot study focused on comparison of protein and glycan composition of ascites in patients with benign and malignant ovarian cancer. Significant differences were found on both glycan and protein levels. Results will be verified on a larger set of patients and compared with a set of control samples.Key words: glycomics - proteomics - ascitic fluid - ovarian cancer This study was supported by projects of the Ministry of Education Youth and Sports - National Sustainability Program I - LO1413; Ministry of Health, Czech Republic - conceptual development of research organization (MMCI, 00209805); Czech Science Foundation 16-04496S.

Abstract
The aim of the present investigation was to evaluate Zingiber officinale paste against Dalton's lymphoma ascites (DLA)-induced tumours in Swiss albino mice. Experimental animals received Z. officinale paste (low dose 100 mg/kg bw and high dose 500 mg/kg bw) orally for eight alternative days. Treatment with Z. officinale paste showed significant increase in haemoglobin level and decrease in aspartate amino transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (γ-GT) level. Z. officinale paste reduced the inflammatory mediators and cytokine levels, such as inducible nitric oxide (iNOS), tumour necrosis factor level (TNF-α) and interleukin-1β (IL-1β). Treatment with Z. officinale paste also significantly increased the antioxidant enzyme level, such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and glutathione transferase (GST), and decreased the lipid peroxidation. Treatment also increased the vitamin C and E levels in treated animals compared with the DLA-bearing host. Histopathological studies also confirmed the protective influence of Z. officinale paste against DLA. The present study suggested that Z. officinale paste could be used as natural spice and a potent antitumour agent.

Abstract
Objective To prepare the fluorescein isothiocyanate (FITC)-labeled mouse monoclonal antibody (mAb) against astrocyte elevated gene-1 (AEG-1) and evaluate its binding ability to tumor cells. Methods The mouse anti-AEG-1 mAb was purified from mouse ascites. The purity and activity of the mAb were identified by SDS-PAGE, Western blotting and immunohistochemistry (IHC). The FITC labeling efficiency was examined by flow cytometry (FCM) and the binding ability of FITC-labeled mAb to tumor cells was detected by FCM and IHC. Results The AEG-1 mAb was successfully purified form mouse ascites, and successfully labeled by FITC. FCM showed that the fluorescence intensity of tumor cells bound with FITC- mAb was significantly strengthened, and the binding rate reached more than 90%. Moreover, the FITC-labeled anti-AEG-1 mAb could specifically recognize and bind to AEG-1 positive tumor cells. Conclusion The mouse anti-AEG-1 mAb has been successfully purified and labeled by FITC, which can specifically bind to tumor cells in vivo and in vitro.

Abstract
OBJECTIVE Increased nitric oxide (NO) production in cirrhotic patients causes splanchnic vasodilation, leading to the development of the hyperdynamic circulatory syndrome. One factor that influences plasma NO concentration is eNOS gene polymorphism; consequently, the aim of this study was to investigate whether the eNOS gene G894T and T-786C polymorphisms play any role in the development of ascites in such patients. PATIENTS AND METHODS Three groups were created: 70 cirrhotic patients with ascites, 69 cirrhotic participants without ascites (stable cirrhosis), and 60 healthy controls. Polymorphisms were determined using polymerase chain reaction (PCR) and melting curve analysis. The plasma nitrite (NO marker) level was measured by deploying the spectrophotometric Griess reaction. RESULTS Plasma nitrite levels in the cirrhosis with ascites and stable cirrhosis groups were significantly higher than in the controls (p < 0.0001). The frequency of GG, GT, and TT genotypes for the eNOS G894T polymorphism in the cirrhosis with ascites group was 55.7%, 38.6%, and 5.7% respectively, while in the stable cirrhosis group these figures were 60.9%, 36.2%, and 2.9%. In the controls, the distribution was 63.3%, 33.3%, and 3.3%, respectively. The frequency of TT, TC, and CC genotypes for the eNOS-786C polymorphism in the first group was 52.9%, 34.2%, and 12.9% respectively; in the second group, this was 46.4%, 42%, and 11.6%, and in the controls, 48.3%, 46.7%, and 5%. There were no significant differences in genotype and allele distributions of the eNOS-786C and eNOS G894T polymorphisms among the groups. CONCLUSIONS Plasma nitrite concentration is enhanced in cirrhotic patients, and there is no relationship between the G894T and eNOS-786C polymorphisms and the development of ascites.

Abstract
BACKGROUND Diagnosis of spontaneous bacterial peritonitis (SBP) is based on a differential ascites leukocyte count which does not provide prognostic information. We performed a pilot study to assess calprotectin in ascites as an alternative diagnostic and prognostic marker. METHODS We collected ascites from patients with liver cirrhosis from March 2012 to July 2013. Routine clinical and laboratory data of the patients were recorded. Ascites calprotectin levels were determined by ELISA. RESULTS Overall, we collected 120 ascites samples from 100 patients with liver cirrhosis and from eight patients with malignant peritoneal effusion as disease control. Samples without infection had significantly lower calprotectin levels (median 34 ng/mL, range 5-795) than SBP samples (median 928 ng/mL, range 21-110,480; p<0.001) and malignant effusions (median 401, range 47-2596 ng/mL; p<0.001). In non-infected ascites, calprotectin levels were higher in Child-Pugh stage B versus C (median 57 ng/mL vs. 17 ng/mL; p<0.001) and in alcoholic versus viral cirrhosis (median 37 ng/mL vs. 10 ng/mL; p=0.015). The ratio of ascites calprotectin to total protein was a better marker for SBP than calprotectin alone (AUROC=0.93; p<0.001; sensitivity 93%, specificity 79%; positive predictive value 60%; negative predictive value 97%). In addition, high levels of the ratio to total protein were associated with poor 30-day survival (p=0.042). CONCLUSIONS The ratio of ascites calprotectin to total protein may be a promising new diagnostic and prognostic marker in patients with liver cirrhosis and SBP and should be evaluated further.

Abstract
Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is a zoonotic pathogen of worldwide importance that causes foodborne infections in humans. Intimin gamma 1 (intimin γ1) is one of the most important outer membrane proteins required for EHEC’s intimate adhesion to epithelial cells. Here, we generated a polyclonal antibody (pAb) and a monoclonal antibody (mAb) against intimin γ1 to develop a double antibody sandwich ELISA (DAS-ELISA) with increased sensitivity and specificity for measuring EHEC O157:H7. To achieve this goal, a rabbit pAb was used as a capture antibody, and a mouse mAb was a detection antibody. No cross-reactivity was observed with the other genera of pathogenic bacteria tested with the DAS-ELISA, which included Salmonella enteritidis, Shigella flexneri type 2, Listeria monocytogenes, Streptococcus suis type 2, and other 18 serotype E. coli. Detection limits of the DAS-ELISA were 1 × 103 CFU/mL for EHEC O157:H7 cultures, 1 × 104 CFU/g before enrichment, and 1 × 102 CFU/g after enrichment of contaminated samples. Field samples (n = 498) were tested using a previously established duplex-PCR method and compared to our DAS-ELISA. The DAS-ELISA had a specificity of 94.4%, a sensitivity of 91.5% and accuracy of 94.0% compared with duplex-PCR. The DAS-ELISA developed here can be applied to EHEC O157:H7 quantification in food, animal, and environmental samples.

Abstract
The most common properties of oncogenes are cell proliferation and the prevention of apoptosis in malignant cells, which, as a consequence, induce tumor formation and dissemination. However, the effects of oncogenes on the tumor microenvironment (TME) have not yet been examined in detail. The accumulation of ascites accompanied by chronic inflammation and elevated concentrations of VEGF is a hallmark of the progression of ovarian cancer. We herein demonstrated the mechanisms by which oncogenes contribute to modulating the ovarian cancer microenvironment. c-MYC and KRAS were transduced into the mouse ovarian cancer cell line ID8. ID8, ID8-c-MYC, or ID8-KRAS cells were then injected into the peritoneal cavities of C57/BL6 mice and the production of ascites was assessed. ID8-c-MYC and ID8-KRAS both markedly accelerated ovarian cancer progression in vivo, whereas no significant differences were observed in proliferative activity in vitro. ID8-KRAS in particular induced the production of ascites, which accumulated between approximately two to three weeks after the injection, more rapidly than ID8 and ID8-c-MYC (between nine and ten weeks and between six and seven weeks, respectively). VEGF concentrations in ascites significantly increased in c-MYC-induced ovarian cancer, whereas the concentrations of inflammatory cytokines in ascites were significantly high in KRAS-induced ovarian cancer and were accompanied by an increased number of neutrophils in ascites. A cytokine array revealed that KRAS markedly induced the expression of granulocyte macrophage colony-stimulating factor (GM-CSF) in ID8 cells. These results suggest that oncogenes promote cancer progression by modulating the TME in favor of cancer progression.
