Immunoregulatory mechanism studies of ginseng leaves on lung cancer based on network pharmacology and molecular docking.

Panax ginseng is one of the oldest and most generally prescribed herbs in Eastern traditional medicine to treat diseases. Several studies had documented that ginseng leaves have anti-oxidative, anti-inflammatory, and anticancer properties similar to those of ginseng root. The aim of this research was to forecast of the molecular mechanism of ginseng leaves on lung cancer by molecular docking and network pharmacology so as to decipher ginseng leaves' entire mechanism.

Screening for differentially expressed genes in endophytic fungus strain 39 during co-culture with herbal extract of its host Dioscorea nipponica Makino.

Strain 39 is an endophytic fungus which was isolated from Dioscorea nipponica Makino (DNM). After Strain 39 co-cultured with ethanol extract of DNM rhizomes for several days, the content of saponins in this culture mixture would be obviously increased. To analyze the mechanism of this microbial transformation, we used the differential display reverse transcription polymerase chain reaction (DDRT-PCR) method to compare the transcriptomes between Strain 39 cultured in normal PD medium and in PD medium which added ethanol extract of DNM rhizomes.

[Pharmacological effects of volatile oil of Valeriana amurensis on CNS].

Objective: To study the pharmacological effects of volatile oil of Valeriana amurensis on central nervous system.

Methods: The pharmacological effects of volatile oil of Valeriana amurensis on the autonomic activities of mice, the sleeping synergistic action of mice with pentoharbital sodium at subthreshold and hypnotic dosages, the sleep phases of rats, the writhing response of mice caused by acetic acid and the convulsion of mice induced by thio-semicarbazide were investigated.

Results: The autonomic activities of mice were significantly inhibited by the volatile oil of Valeriana amurensis.
