ABSTRACT
Objective: Andrographis paniculata is a well-known medicinal plant in Southeast Asia, India and China. The plant contains andrographolide (AN), a very important phytochemical used in various health problems. However, AN is low in oral absorption bioavailability of AN due to the rapid clearance and high protein binding capacity. Methods: The present study was aimed to develop a nano-phytovesicular formulation of semi-purified AN extracts from a naturally occurring phospholipid (soya phosphatidylcholine) in order to increase the oral absorption and antihyperglycemic activity in rats. Results: The nano-phyto vesicle of semi-purified AN extracts equivalent to 25 mg /kg AN significantly protected the hyperglycemic condition of rats. The in vitro and in vivo experiments results proved that the nano- phytovesicular system of plant extracts containing AN produced better oral absorption, bioavailability and improved antihyperglycemic activity compared with that of free AN at dose of 50 mg/kg. Conclusion: Hence, the prepared semi-purified extract nano-phytovesicular system is helpful in solving the problem of rapid clearance of AN.
ABSTRACT
Hesperetin, an abundant bioactive component of citrus fruits, is poorly water-soluble, resulting in low oral bioavailability. We developed new formulations to improve the water solubility, antioxidant activity, and oral absorption of hesperetin. Two nano-based formulations were developed, namely hesperetin-TPGS (D-α-tocopheryl polyethylene glycol 1000 succinate) micelles and hesperetin-phosphatidylcholine (PC) complexes. These two formulations were prepared by a simple technique called solvent dispersion, using US Food and Drug Administration (FDA)-approved excipients for drugs. Differential scanning calorimetry (DSC) and dynamic light scattering (DLS) were used to characterize the formulations' physical properties. Cytotoxicity analysis, cellular antioxidant activity assay, and a pharmacokinetic study were performed to evaluate the biological properties of these two formulations. The final weight ratios of both hesperetin to TPGS and hesperetin to PC were 1:12 based on their water solubility, which increased to 21.5- and 20.7-fold, respectively. The hesperetin-TPGS micelles had a small particle size of 26.19 nm, whereas the hesperetin-PC complexes exhibited a larger particle size of 219.15 nm. In addition, the cellular antioxidant activity assay indicated that both hesperetin-TPGS micelles and hesperetin-PC complexes increased the antioxidant activity of hesperetin to 4.2- and 3.9-fold, respectively. Importantly, the in vivo oral absorption study on rats indicated that the micelles and complexes significantly increased the peak plasma concentration (Cmax) from 2.64 μg/mL to 20.67 and 33.09 μg/mL and also increased the area under the concentration-time curve of hesperetin after oral administration to 16.2- and 18.0-fold, respectively. The micelles and complexes increased the solubility and remarkably improved the in vitro antioxidant activity and in vivo oral absorption of hesperetin, indicating these formulations' potential applications in drugs and healthcare products.

ABSTRACT
Objective: To evaluate effects of docosahexaenoic acid-enriched phosphatidylcholine (DHA-PC) on cytokine production induced by lipopolysaccharide (LPS). Methods: The culture supernatants of splenocytes exposed to DHA-PC along with LPS were harvested to determine the production of Th 1 (IFN- γ and IL-2) and Th2 [IL-4, IL-5, IL-6 and IL-12/IL-23(p40)] cytokines. Cytokines were measured using ELISA. Results: Co-administration of DHA-PC with LPS resulted in significantly lower IL-2 expression compared to that observed with administration of only LPS (P<0.01). Treatment with DHA-PC and LPS significantly increased IL-5 expression (P<0.01). Moreover, co-administration of DHA-PC with LPS significantly decreased IL-6 and IL-12/IL-23(p40) expressions compared to that observed with administration of only LPS (P<0.01). Conclusions: Our results suggest that DHA-PC inhibits pro-inflammatory cytokines [IL-2, IL-6 and IL-12/IL-23(p40)] expression on induction of inflammation.

Desde a primeira publicação a respeito, em 2001, a aplicação de injeções lipolíticas para gordura localizada tornou-se um procedimento amplamente utilizado na clínica. Consiste de múltiplas injeções subcutâneas de compostos lipolíticos, que podem ter diversos mecanismos de ação. O fármaco mais utilizado atualmente, o desoxicolato de sódio, foi descoberto por acaso, em uma associação com fosfatidilcolina em que sua única função era de veículo da fórmula. Conforme estudos foram sendo realizados, concluiu-se que a ação no tecido era devido ao desoxicolato, um sal biliar que emulsiona os lipídios da membrana celular, resultando em lise do adipócito e consequente necrose do tecido adiposo. Seus principais efeitos adversos, muito frequentemente relatados, incluem dor intensa, edema e formação de nódulos fibrosos nos pontos aplicados. Em decorrência de falhas na aplicação, alguns efeitos adversos mais graves podem ocorrer, como injúria do nervo facial e infecções persistentes. Apesar destes, a utilização de desoxicolato de sódio na camada subcutânea apresenta resultados muito positivos, como publicado em diversos ensaios clínicos, inclusive com relação à satisfação do paciente perante o desfecho final, sendo, portanto, uma boa escolha de técnica para contorno corporal e diminuição de depósitos de gordura localizados.

Since the first paper, in 2001, injection lipolysis for localized fat deposits became a widely used procedure in the clinics. It consists basically of multiple subcutaneous injections of lipolytic compounds, with many different mechanisms of action. The most used drug nowadays is sodium deoxycholate, initially thought to be only the solubilizing vehicle in the phosphatidilcholine formula. As studies were performed, it was concluded that the changes seen in the tissue was due to sodium deoxycholate, a biliary salt which emulsifies membrane lipids, resulting in adipocyte lysis and consequent adipose tissue necrosis. Its main adverse events include pain, oedema and fibrous nodules. Due to poor technique, more serious adverse events may happen, such as nerve injury or persistent infection by mycobacterium. In spite of these, the use of sodium deoxycholate presents great results, as published in many clinical trials, including patient's satisfaction at the end of the treatment, which is of much value in the aesthetics field. Therefore, mesotherapy using sodium deoxycholate is a good choice for body contouring and localized fat deposits. (AU)

Objective To study the protective effect of polyene phosphatidylcholine on hepatic injury induced by oxaliplatin and 5?fluorouracil. Methods A subcutaneous tumor model was established by transplanting colocarcinoma HCT116 cells into 30 nude mice,which were random?ized into three groups. The polyene phosphatidylcholine group was injected with polyene phosphatidylcholine(85 mg · kg-1 · d-1)and 5?fluorouracil (20 mg·kg-1·d-1)for 7 days,and then injected with oxaliplatin(6 mg·kg-1·d-1)for 1 day. The hepatic injury group was injected with 5?fluoroura?cil(20 mg·kg-1·d-1)for 7 days and oxaliplatin(6 mg·kg-1·d-1)for 1 day. The tumor?bearing blank group was injected with normal saline. Hepat?ic injury was observed with ultrathin pathological sections. Liver homogenates were prepared to detect superoxide dismutase(SOD)and catalase (CAT)activity. Results In the hepatic injury group,pathological sections revealed dissolved cellular cytoplasm,mitochondrial membrane dam?age,cell membrane edema,and fuzzy,sinusoidal cell expansion . There were no obvious hepatic injuries observed in the polyene phosphatidylcho?line group. The expression of SOD and CAT were lower in the hepatic injury and polyene phosphatidylcholine groups compared to the tumor?bear?ing blank group(P<0.05). The expression of SOD and CAT were higher in the polyene phosphatidylcholine group compared to the hepatic injury group(P<0.05). Conclusion Polyene phosphatidylcholine has a protective effect on hepatic injury induced by oxaliplatin and 5?fluorouracil, which may be related to its effect on membrane repair and inhibition of oxidative stress.
ABSTRACT
Objective · To obtain the latest data on phospholipid composition of human milk in Shanghai and compare the differences in phospholipid composition at different lactation stages. Methods · Healthy postpartum women who delivered full-term infants in the Obstetrical Department of Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine between April and July, 2016 were enrolled. The colostrum, transitional milk, and mature milk were collected at Day 3, 10, and 45 after delivering babies, respectively. Human milk fat was extracted with Folch's method and phospholipids were separated with solid phase extraction (SPE). The phosphatidylethanolamine, phosphatidylcholine, and sphingomyelin were quantitatively analyzed with HPLC/VWD. The differences in phospholipid composition at different lactation stages were compared with univariate analysis of variance and Games-Homell test. Results · One hundred women who provided at least one breast milk sample were enrolled. A total of 70 colostrum samples, 96 transitional milk samples, and 82 mature milk samples were collected. The total phospholipid content of mature milk [(281.93±118.54) μg/g] was significantly lower than that of colostrum [(381.99±205.90) μg/g]. At all lactation stages, the relative content of phosphatidylcholine was the highest (53.74%-59.36%), followed by sphingomyelin (28.12%-32.74%). The relative content of phosphatidylethanolamine was constant (P=0.617), the relative content of phosphatidylcholine gradually decreased (P=0.000), and that of sphingomyelin gradually increased (P=0.000) during the lactation. Conclusion · Sphingomyelin and phosphatidylcholine are major components of human milk phospholipids. The amount of phospholipids varies during the lactation. The total amount of phospholipids is lower in mature milk than in colostrum and transitional milk. The relative content of phosphatidylethanolamine is consistent at all lactation stages, the relative content of phosphatidylcholine gradually decreases, and that of sphingomyelin gradually increases.
ABSTRACT
Objective To discuss the impact of improved pipe-washing on blockage of PICC for infusion of polyene phosphatidylcholine injection (PPI). Methods A total of 15 patients treated with infusion of PPI from April 2014 to March 2015 were chosen as the control group by convenience sampling method, while another 18 patients treated with PPI from April 2015 to March 2016 were selected as the experimental group. In the control group the pipes were washed with 0.9%10 mL sodium chloride injection before PPI infusion, while in the experimental group improved pipe washing method was applied.
