The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.

[Objective] To compare the antipyretic and anti-inflammatory actions and acute toxicity between Chuanxinlian Soft Capsules (CSC) and Chuanxinlian Tablets. [Methods] Antipyretic action of CSC was observed on rabbit fever models induced by lipopolysaccharide (LPS) and rat fever models induced by baker's yeast. Rat models with pedal swelling induced by carrageenin, mouse models with auricle swelling induced by dimethylbenzene and mouse models with celiac capillary hyperpermeability induced by acetic acid were used to observe the anti-inflammatory action oi CSC. Its acute toxicity in mice was also evaluated. [Results] High- and moderate-dose CSC reduced fever in rabbits induced by LPS (P 0.05). High-, moderate- and low-dose CSC has an inhibitory effect on acute inflammatory exudation (P

Rubus corchorifolius(Shanmei or mountain berry,2n=14)is widely distributed in China,and its fruits possess high nutritional and medicinal values.Here,we reported a high-quality chromosome-scale genome assembly of Shanmei,with contig size of 215.69 Mb and 26,696 genes.Genome comparison among Rosaceae species showed that Shanmei and Fupenzi(Rubus chingii Hu)were most closely related,followed by blackberry(Rubus occidentalis),and that environmental adaptation-related genes were expanded in the Shanmei genome.Further resequenc-ing of 101 samples of Shanmei collected from four regions in the provinces of Yunnan,Hunan,Jiangxi,and Sichuan in China revealed that among these samples,the Hunan population of Shanmei possessed the highest diversity and represented the more ancestral population.Moreover,the Yunnan population underwent strong selection based on the nucleotide diversity,linkage dise-quilibrium,and historical effective population size analyses.Furthermore,genes from candidate genomic regions that showed strong divergence were significantly enriched in the flavonoid biosyn-thesis and plant hormone signal transduction pathways,indicating the genetic basis of adaptation of Shanmei to the local environment.The high-quality assembled genome and the variome dataset of Shanmei provide valuable resources for breeding applications and for elucidating the genome evo-lution and ecological adaptation of Rubus species.
