Advances in the treatment of malignant ascites in China.

PURPOSE: Malignant ascites (MA) often occurs in recurrent abdominal malignant tumors, and the large amount of ascites associated with cancerous peritonitis not only leads to severe abdominal distension and breathing difficulties, but also reduces the patient's quality of life and ability to resist diseases, which usually makes it difficult to carry out anti-cancer treatment. The exploration of MA treatment methods is also a key link in MA treatment. This article is going to review the treatment of MA, to provide details for further research on the treatment of MA, and to provide some guidance for the clinical treatment of MA. METHOD: This review analyzes various expert papers and summarizes them to obtain the paper. RESULT: There are various treatment methods for MA, including systemic therapy and local therapy. Among them, systemic therapy includes diuretic therapy, chemotherapy, immunotherapy, targeted therapy, anti angiogenic therapy, CAR-T, and vaccine. Local therapy includes puncture surgery, peritoneal vein shunt surgery, acellular ascites infusion therapy, radioactive nuclide intraperitoneal injection therapy, tunnel catheter, and intraperitoneal hyperthermia chemotherapy. And traditional Chinese medicine treatment has also played a role in enhancing efficacy and reducing toxicity to a certain extent. CONCLUSION: Although there has been significant progress in the treatment of MA, it is still one of the clinical difficulties. Exploring the combination or method of drugs with the best therapeutic effect and the least adverse reactions to control MA is still an urgent problem to be solved.

An integration of UPLC-DAD/ESI-Q-TOF MS, GC-MS, and PCA analysis for quality evaluation and identification of cultivars of Chrysanthemi Flos (Juhua).

BACKGROUND: Chrysanthemi Flos (CF), as a popular traditional Chinese medicine (TCM), has five main cultivars in China, namely "Chuju", "Boju", "Gongju", "Huaiju" and "Hangju". Due to their habitats and processing methods, great quality variations occur yet no systematical study has ever been carried out to evaluate such variations. PURPOSE: In this study, we aim to establish a new approach that can serve both as a quality control method and as an identification method for cultivars of CF. METHOD: The components in CF samples were identified by a combination of UPLC-ESI-Q-TOF/MS and GC/MS. Furthermore, a multimodal quantitative method was established by UPLC-UV coupled with principal component analysis (PCA) and the similarity evaluation system (SES), which was used to control and identify four cultivars of CF. RESULTS: 18 compounds of flavonoids and caffeoylquinic acids were identified and ten of them were quantified using UPLC-ESI-Q-TOF/MS. Different cultivars of CF could be clearly distinguished with the fingerprints evaluation and principal component analysis (PCA). A total of 74 volatile compounds were detected by GC/MS. The distinctness of volatile components was observed. By the combination of UPLC-ESI-Q-TOF/MS and GC/MS, an identification and quality control method for CF was successfully established. CONCLUSION: The combination of UPLC-ESI-Q-TOF/MS and GC/MS could act as a comprehensive multimodal method for both identification and quality control of herbal medicines. This study provided new insights into the overall evaluation method for herbal medicines possessing different cultivars.

Zein based oil-in-glycerol emulgels enriched with ß-carotene as margarine alternatives.

Structuring edible oils into solid lipids without saturated and trans fats has attracted increasing interest due to the benefits for human health and promises potential as novel delivery systems for lipophilic bioactive ingredients. The study shows that a zein stabilized high (ϕ=0.6) oil-in-glycerol (O/G) emulgels enriched with ß-carotene was performed, by a facile one-step homogenization. Rheological measurements and morphologies observations indicated that increasing ß-carotene resulted in a progressive strengthening of gel-like network and improving their spreadability in the O/G emulgels stabilized by zein, which was closely related to the hydrophobic interaction of zein and ß-carotene. The formation of emulgels significantly enhanced the UV photo-stability of ß-carotene, and more than 88% of ß-carotene was retained in 64h storage under UV exposure, and consequently retarded oil oxidation while storage. Further, cakes prepared using zein-based O/G emulgels as a margarine alternative showed comparable functionalities (texture and sensory attributes) to the standard cake.

Effect of interfacial composition and crumbliness on aroma release in soy protein/sugar beet pectin mixed emulsion gels.

BACKGROUND: In this study, soy protein isolate/sugar beet pectin (SPI/SBP) emulsion gels were prepared through an enzymatic gelation process. The effects of emulsifier (SBP, SPI or SPI/SBP complex) and emulsification process on the microstructure, texture, breakdown properties and aroma release behavior of resulting emulsion gels were investigated. RESULTS: Oil emulsification by SBP/SPI complex resulted in a higher amount of emulsifier absorbing on the oil-water interface than by SBP and SPI alone, indicating that a more compact interfacial network was formed. Flocculation of oil droplets was observed and corresponding emulsion gels exhibited lower fracture force and strain when the oil was emulsified by SPI and SBP/SPI complex. Moreover, emulsion gels with small droplets produced a greater quantity of small fragments after mastication. However, microstructure did not have a significant effect on breakdown properties of emulsion gels. Headspace gas chromatography analysis showed that the release rate of ethyl butyrate before and after mastication was significantly lower in emulsion gel with more compact network, but the release of aroma compounds with higher hydrophobicity did not show a significant influence of the microstructure and texture of emulsion gel. CONCLUSION: This finding provides a useful application for designing semi-solid foods with desirable flavor perception. © 2016 Society of Chemical Industry.

[Chemical constituents from stems of Hedyotis hedyotidea and their immunosuppressive activity].

Hedyotis hedyotidea has been traditionally used for the treatment of arthritis, cold, cough, gastro-enteritis, headstroke, etc. But few studies have screened the active compounds from extracts of H. hedyotidea. In this study, the structure of the chemical constituents from stems of H. hedyotidea were determined and the immunosuppressive activity of the compounds was evaluated. The compounds were separated and purified with silica gel, gel column chromatographies and preparative HPLC, and their structures were identified by spectral methods such as MS and NMR. Eleven compounds were obtained and identified as(6S,9S) -vomifoliol (1), betulonic acid (2), betulinic acid (3), betulin(4), 3-epi-betulinic acid (5), ursolic acid (6), ß-sitosterol (7), stigmast-4-en-3-one (8), 7ß-hydroxysitosterol (9), (3ß,7ß) -7-methoxystigmast-5-en-3-ol (10) and morindacin (11). This is the first report of compounds 1, 2, 4, 8, 9, 10 and 11 from H. hedyotidea. Compounds 1, 2 and 8-11 were firstly isolated from the genus Hedyotis, and compounds 9 and 10 were isolated from the family Rubiaceae for the first time. The immunosuppressive activity of these compounds was tested using the lymphocyte transsormationtest. Compounds 4, 6 and 9 showed significant immunosuppressive activity.

[Effect of ASO Blood Stasis Syndrome Serum on Vascular Endothelial Cell Injury and Regulation of Taohong Siwu Decoction on it].

OBJECTIVE: To explore the effect of arteriosclerosis obliterans (ASO) blood stasis syndrome (BSS) serum on vascular endothelial cell injury and to study the regulation of Taohong Siwu Decoction (TSD) on it. METHODS: Umbilical vein endothelial cell culture system was established. The serum endothelial cell injury model with ASO BSS was prepared. Low, medium, and high concentrations TSD containing serums were respectively added. The endothelial cell proliferation activity was observed by MTT method. Ultrastructures of endothelial cells were observed under transmission electron microscope. Changes of intracellular calcium ion concentration and the cytoskeleton were observed under laser confocal microscope. Contents of ET, NO, and transforming growth factor beta1 (TGF-beta1) in endothelial cell culture supernatant were detected by ELISA. RESULTS: In ASO BSS serum group endothelial cell proliferation activities decreased, the cell structure was obviously destroyed, calcium ion concentration increased, contents of ET, NO and TGF-beta1 increased significantly (P < 0.01), and ET/NO ratio was imbalanced. After incubating with TSD drug containing serum, endothelial cell proliferation activities and injured cell structures were obviously improved; ET, NO and TGF-beta1 levels decreased (P < 0.05, P < 0.01), ET/NO ratios approximated to the normal level. CONCLUSION: The main mechanism of TSD for treating ASO ASS lied in improving injured vascular endothelial cells and endocrine disorder.
