A review on antitumor effect of pachymic acid.

Poria cocos, also known as Jade Ling and Songbai taro, is a dry fungus core for Wolfiporia cocos, which is parasitic on the roots of pine trees. The ancients called it "medicine of four seasons" because of its extensive effect and ability to be combined with many medicines. Pachymic acid (PA) is one of the main biological compounds of Poria cocos.

Beneficial Effects of Traditional Chinese Medicine in the Treatment of Premature Ovarian Failure.

Premature ovarian failure (POF) is characterized by hormonal disorders, amenorrhea, and premature loss of fertility potential in women of reproductive age. Several studies have been conducted on the effectiveness of traditional Chinese medicine (TCM) in treating POF. TCM relied primarily on apoptosis, immunity, and aging to treat POF based on the studies of domestic and foreign literature.

The main goal of our study was to characterize the population pharmacokinetics of vancomycin in critically ill Chinese neonates to develop a pharmacokinetic model and investigate factors that have significant influences on the pharmacokinetics of vancomycin in this population. The study population consisted of 80 neonates in the neonatal intensive care unit (ICU) from which 165 trough and peak concentrations of vancomycin were obtained. Nonlinear mixed effect modeling was used to develop a population pharmacokinetic model for vancomycin.

Anti-hypercholesterolemic Effect of Berbamine Isolated from in Hypercholesterolemic Zebrafish Induced by High-Cholesterol Diet.

The anti-hypercholesterolemic effect of berbamine (BBM) isolated from (RC) was investigated in hypercholesterolemic zebrafish model induced by high-cholesterol (HC) diet. Zebrafish embryo assay revealed no significant difference in morphology and cell death with the treatment of BBM less than 20 μg/mL. In zebrafish larvae, the fluorescently labeled cholesterol in caudal artery was reduced dose-dependently after BBM treatment.

Identification of key differentially expressed genes associated with non‑small cell lung cancer by bioinformatics analyses.

Increasing evidence has indicated that the abnormal expressions of certain genes serve important roles in tumorigenesis, progression and metastasis. The aim of the present study was to explore the key differentially expressed genes (DEGs) between non‑small cell lung cancer (NSCLC) and matched normal lung tissues by analyzing 4 different mRNA microarray datasets downloaded from the Gene Expression Omnibus (GEO) database. In improving the reliability of the bioinformatics analysis, the DEGs in each dataset that met the cut‑off criteria (adjust P‑value <0.

8-Cetylberberine inhibits growth of lung cancer in vitro and in vivo.

Aims: This study is aimed at detecting the anti-tumor efficacy of a new berberine (BBR) derivative 8-cetylberberine (HBBR), which has a significant improvement in hydrophobicity and pharmacological effects compared to BBR.

Main Methods: The human non-small lung cancer cell line A549 and normal human lung epithelial cells (MRC-5) were cultured to observe inhibition in vitro. Cell viability was analyzed via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

Coptisine from Rhizoma Coptidis Suppresses HCT-116 Cells-related Tumor Growth in vitro and in vivo.

Colorectal cancer is one of the most common causes of cancer-related death in humans. Coptisine (COP) is a natural alkaloid from Coptidis Rhizoma with unclear antitumor mechanism. Human colon cancer cells (HCT-116) and xenograft mice were used to systematically explore the anti-tumor activity of COP in this study.

Comparative effect of berberine and its derivative 8-cetylberberine on attenuating atherosclerosis in ApoE mice.

Berberine (BBR), one of the main bioactive compounds in Rhizoma coptidis, has multiple pharmacological activities. It has been reported that 8-cetylberberine (8-BBR-C16) has increased anti-microbial property in vivo and a higher bioavailability in hamsters. Therefore, in the present study, we used apolipoprotein E-deficient mice (ApoE) as an atherosclerosis model to investigate the anti-atherosclerosis effects of 8-BBR-C16.

Activation of Akt and JNK/Nrf2/NQO1 pathway contributes to the protective effect of coptisine against AAPH-induced oxidative stress.

Coptisine (COP) is one of the main active constituents of Coptidis Rhizoma. Previous studies have clarified that COP possesses antioxidant activity, but its defensive effects against pathological characteristics accompanied by oxidative damage in animal models and antioxidant mechanism are still unclear. Therefore, our purpose was to confirm the antioxidant activity of COP and explore its mechanism of action.
