Objective To explore the culture method of mass amplification for tumor-infiltrating lymphocytes (TILs) from malignant pleural/ascites in vitro, and identify the function and molecular phenotype of these amplified cells. Methods The pleural/ascites fluid was extracted under aseptic conditions, and lymphocytes were isolated by density gradient centrifugation. Then TILs were amplified by the program based on combined IFN-γ, OKT3 and IL-2, and the cell morphology and growth rate were recorded. The molecular phenotypes of the amplified lymphocytes were analyzed by Flow cytometry, and the killing ability against tumor cells was detected by CCK-8 assay. Results In this culture program, TILs remained in good condition until the 26th day, and the proliferation rate began to decrease on the 30th day. The proportions of CD4-CD8+ and CD8+CD56+ T cells gradually increased as cell culture time extended while the proportions of CD4+CD25+ T cells decreased gradually. Unlike the proportions prior to amplification, the proportions of SLAMF7, CD45RO, PD-1 and granzyme B positive cells in T lymphocyte subpopulation were significantly increased, meanwhile, the expression of exhausted T-cell marker CD57 was also gradually increased. The cytotoxicity of amplified CD8+ T cells from TILs was significantly stronger than that from PBMC, and the cytotoxicity reached the peak at the effect-target ratio of 10:1 and was significantly different among tumor cell types. Conclusion A culture program for TILs amplification from cancerous thoracic/ascites is established. The method is simple and efficient. The effector cells are mainly CD8+ T lymphocytes with active phenotype.

Influenza C virus is an important respiratory pathogen not only infecting people, but also pigs, dogs, and other animals. Polymerase is central to the replication of influenza C virus and is an important target for studying the mechanism of viral replication. However, there is no commercial monoclonal antibody (MAb) targeting influenza C virus polymerase, which hampers the development of relevant research to some extent. In order to prepare MAb targeting the polymerase basic protein 2 (PB2) of influenza C virus, influenza C virus RNA-dependent RNA polymerase (RdRp, consists of PB1, PB2 and P3) was co-immunoprecipitated with Flag-tagged human acidic nuclear phosphoprotein 32A (huANP32A-Flag) from 293T cells based on the interaction between huANP32A and influenza virus RdRp. The purified RdRp was used as antigen to immunize BALB/c mice. Six positive hybridoma cell lines (7B11-5, 8A4-5, 13D9-6, 8D4-1, 8D4-3, 9F9-4) that stably secrete and recognize PB2 MAb were screened by indirect ELISA and Western blotting. The subtypes of MAb 7B11-5, 8A4-5, 8D4-1 and 8D4-3 antibody were identified as IgG1, the subtypes of MAb 13D9-6 and 9F9-4 were IgG2a and IgG3, respectively. All the light chains of the MAbs were κ chain. A hybridoma cell line 8D4-1 with high titer was further selected to prepare ascites. The titer of mouse ascites antibody was determined to be 1:64 000. Western blotting results showed that the MAb 8D4-1 had a specific immune response with ICV PB2; laser confocal assay showed that the prepared MAb 8D4-1 accurately detected the subcellular localization of PB2 subunits. Moreover, ICV RdRp was highly enriched by ANP32A. The high specific of the prepared PB2 MAb 8D4-1 may facilitate the polymerase detection, structural analysis and mechanism study of influenza C virus.

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.

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.

PURPOSE: Adipose stromal cells (ASCs) play an important regulatory role in cancer progression and metastasis by regulating systemic inflammation and tissue metabolism. This study examined whether visceral and subcutaneous ASCs (V- and S-ASCs) facilitate the growth and migration of ovarian cancer cells. MATERIALS AND METHODS: CD45– and CD31– double-negative ASCs were isolated from the subcutaneous and visceral fat using magnetic-activated cell sorting. Ovarian cancer cells were cultured in conditioned media (CM) obtained from ASCs to determine the cancer-promoting effects of ASCs. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, Boyden chamber assay, and western blotting were performed to determine the proliferative activity, migration ability, and activation of the JAK2/STAT3 pathway, respectively. RESULTS: CM from ASCs enhanced the migration of the ovarian cancer line, SKOV3, via activation of the JAK2/STAT3 signaling pathway. Interestingly, in response to ASC-CM, the ascites cells derived from an ovarian cancer patient showed an increase in growth and migration. The migration of ovarian cancer cells was suppressed by blocking the activation of JAK2 and STAT3 using a neutralizing antibody against interleukin 6, small molecular inhibitors (e.g., WP1066 and TG101348), and silencing of STAT3 using siRNA. Anatomical differences between S- and V-ASCs did not affect the growth and migration of the ovarian cancer cell line and ascites cells from the ovarian cancer patients. CONCLUSION: ASCs may regulate the progression of ovarian cancer, and possibly provide a potential target for anticancer therapy.

OBJECTIVE: To describe the nutritional status of women with peritoneal metastasis (PM) from recurrent ovarian, fallopian, or peritoneal cancer and to assess longitudinal variations of the cachexia-anorexia syndrome (CAS) during palliative pressurized intraperitoneal aerosol chemotherapy (PIPAC). METHODS: Nutritional assessment included body mass index (BMI), bioelectrical impedance analysis (BIA), and blood chemistry. CAS presence/absence was recorded before and during repeated cycles (1–11) of PIPAC. RESULTS: Eighty-four patients with peritoneal cancer (n=5) or PM from recurrent ovarian (n=77) or fallopian tube (n=2) cancer were included. At baseline, resting metabolism (RM) (1,432±172 kcal/day), visceral fat level (7.5±3.2), skeletal muscle mass (27.2%±4.6%), upper arm circumference (27.9±4.6 cm), lower leg circumference (35.1±3.9 cm), serum parameters (albumin [3.5±0.7 g/dL], total protein [6.3±0.9 g/dL], and transferrin [202±60 mg/dL]) were below normal limits. C-reactive protein (CRP) (4.3±6.8 mg/dL), caliper body fat (35.7%±6.3%), and total body fat mass (35.6%±8.5%) were above normal limits. Nineteen/84 (23%) patients had CAS at baseline. Deterioration or stabilization/improvement of CAS was observed in 9/55 (16.4%) and 46/55 (83.6%) patients with follow-up data, respectively. Baseline body fat mass, visceral fat level, skeletal muscle mass, caliper body fat, BMI, ascites, Karnofsky index, RM, and CRP, as well as tumor response were not predictive of CAS deterioration. CONCLUSION: Nutritional decline and onset or deterioration of CAS are difficult to predict. Careful measuring and monitoring of nutritional parameters and CAS in all patients seems to be necessary in order to identify those patients in need of enteral/parenteral nutrition support.

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

OBJECTIVE: To investigate the clinical characteristics of fetal hydrops and to find the antenatal ultrasound findings predictive of adverse perinatal outcome. METHODS: This is a retrospective study of 42 women with fetal hydrops who delivered in a tertiary-referral center from 2005 to 2013. Fetal hydrops was defined as the presence of fluid collection in > or =2 body cavities: ascites, pleural effusion, pericardial effusion, and skin edema. Predictor variables recorded included: maternal characteristics, gestational age at diagnosis, ultrasound findings, and identifiable causes. Primary outcome variables analyzed were fetal death and neonatal death. RESULTS: The mean gestational age at diagnosis was 29.3+/-5.4 weeks (range, 18 to 39 weeks). The most common identifiable causes were cardiac abnormality (10), followed by syndrome (4), aneuploidy (3), congenital infection (3), twin-to-twin transfusion syndrome (3), non-cardiac anormaly (2), chorioangioma (2), inborn errors of metabolism (1), and immune hydrops by anti-E antibody isoimmunization (1). Thirteen cases had no definite identifiable causes. Three women elected termination of pregnancy. Fetal death occurred in 4 cases. Among the 35 live-born babies, only 16 survived (54.0% neonatal mortality rate). Fetal death and neonatal mortality rate was not significantly associated with Doppler velocimetry indices or location of fluid collection, but increasing numbers of fluid collection site was significantly associated with a higher risk of neonatal death. CONCLUSION: The incidence of fetal hydrops in our retrospective study was 24.4 per 10,000 deliveries and the perinatal mortality rate was 61.9% (26/42). The number of fluid collection sites was the significant antenatal risk factor to predict neonatal death.

OBJECTIVETo observe the effect of Gansui Banxia Tang plus-minus Gansui and Gancao anti-drug combination on hepatic and renal functions in malignant ascites rats to explore whether the efficacy or toxicity associated with the anti-drug combination.
METHODThe male wistar rats were randomly divided into a blank group, model group, furosemide group, Gansui Banxia Tang group, Gansui Banxia Tang removed Zhigancao group, Gansui Banxia Tang removed Cugansui group, Gansui Banxia Tang removed Zhigancao and Cugansui group. In addition to normal feeding, every morning except for the blank group and model group, the rest of the group was given drugs, the control group and the model group was given distilled water, the volume is 10 mL x kg(-1). Administered five days, all rats were fasted but except water for 24 hours to collect urine. Administered nine days all rats were fasted but except water for 12 hours, we need to weigh weight of rats. When we remove the ascites, we also need to weigh weight of rats. We use the weight before removing ascites minus weight after removing ascites to indirectly measure the amount of ascites. When we remove the ascites, we need to abdominal aortic blood, centrifuge testing renin, angiotensin II, aldosterone, antidiuretic hormone and other indicators.
RESULTThe effect of Gansui Banixa Tang on increasing the net weight, lowering abdominal circumference and body weight ratio, lowering renin, angiotensin, aldosterone, antidiuretic hormone is better than the other treatment group.
CONCLUSIONIn diuresis party, the group of Gansui Banxia Tang is better than the group of Gansui Banxia Tang remove Zhigancao or Cugansui or Zhigancao and Cugansui, renin-angiotensin-aldosterone system may play a diuretic effect of its one way.

OBJECTIVETo investigate the intervention effect of Danggui Shaoyao San on rats with cirrhotic ascites, and discuss the effect of arginine vasopressin (AVP) on cirrhotic ascites.
METHODMale SD rats were randomly divided into the control group, the model group, Danggui Shaoyao San low, middle and high dose groups. The cirrhotic ascites rat model was established by CCl4 combined with phenobarbital. Their urines were collected at 24 h to observe urine excretion of each group. Filter papers were used to determine the amount of ascites. The levels of serum alanine aminotransferasa (ALT) , aspartate aminotransferase (AST) were detected by the automatic biochemistry analyzer. Plasma prothrombin time (PT) was evaluated by the blood coagulation analyzer. The concentration of AVP in plasma was detected by enzyme-linked immunosorbent assay (ELISA). Pathological changes in livers were observed by HE staining.
RESULTCompared with the model group, the Danggui Shaoyao San group showed significant improvement in live indexes, with notable decrease in serum ALT and AST and the time of PT, improvement in liver pathological changes. Simultaneously, the amount of ascites decreased to varying degrees, with notable increase in urine in 24 h and decrease in AVP concentration in plasma.
CONCLUSIONDanggui Shaoyao San can notably improve liver functions of rats with cirrhotic ascites, reduce the generation of ascites and delay the progress of liver pathological changes. Its mechanism may be related to AVP.
