Phellinus is a kind of rare medicinal fungus that has a variety of physiological activities include anti-cancer, anti-liver fibrosisa, antioxidant and so on. Phellinus contains polysaccharides, steroids, terpenoids, flavonoids, pyrone, furan, alkaloids and other substances. Polysaccharide extracts of phellinus showed obvious antitumor effect and has been a hot research field in recent years. It was also found other extracts of phellinus such as ethyl acetate extract exhibited anticancer activity. Thus, the antitumor effect of different extract, especially the anti-cancer mechanism were discussed in this review.

8.Effects of isoflurane on neuronal apoptosis In aged rats
Chinese Journal of Anesthesiology 2009;29(7):610-612
Objective To investigate the effects of different concentrations of isoflurane on neuronal apoptosis in hippocampus and cerebral cortex in the aged rats. Methods Ninety female pathogen-free SD rats 22-24 months old weighing 497-593 g were randomly divided into 3 groups: group Ⅰ oxygen group inhaled air enriched with 40% O2,groupⅡ and Ⅲ were anesthetized with 1.2% and 1.8% isoflurane for 3 h respectively. Morris water maze was used to assess the cognitive function. The animals were killed at 24 and 72 h and on the 7th day after emergence from anesthesia and their brains were removed. Neuronal apoptosis in hippocampus and cerebral cortex was detected by TUNEL. Results The average escape latency was significantly longer on the 2nd and 3rd day after isoflurane anesthesia in isoflurane group than in oxygen group (P < 0.05 ). The neuronal apoptesis rate was significantly higher in the 2 isoflurane group than in oxygen group (P < 0.05 or 0.01 ). Conclusion Isoflurane anesthesia can result in transient cognitive dysfunction, and the mechanism may be involved in apoptosis in cerebral cortex in the aged rats.
9.Gene polymorphisms predict efficacy and toxicity of chemotherapy for colorectal cancer
Tumor 2010;(2):164-169
Objective:The efficacy and toxicity of anticancer drugs differ in different tumor patients. It could not meet the requirements of optimization of tumor treatment if only under the guidance of clinical and pathologic characteristics. More and more attention is focused on individualized therapy based on individual gene profiles. It has been identified that gene polymorphisms are responsible for different outcomes of individuals. Gene polymorphisms, including sequence polymorphism and single nucleotide polymorphism, will decrease the clinical efficacy of chemotherapeutic drugs or increase adverse reactions by influencing the expression or activity of the corresponding proteins. In recent years several gene polymorphisms related to drug metabolism, transportation, or inactivation may affect the outcomes of chemotherapy and the frequency of adverse reactions. Identification of the polymorphism genes is important for individual therapy for tumor patients.
10.EFFECTORSEARCH: Software for identifying effectors of T3SS in bacterial species
Chinese Journal of Zoonoses 2012;(6):528-535
Many gram-negative bacteria use the type Ⅲ secretion system (T3SS) to inject virulence proteins (effectors) directly into host cells.These effectors play a central role in pathogen interactions,and their molecular structures are highly variable.Previous researchers have used particular motifs common to all effectors in order to identify a full suite of candidate effectors of T3SS in the genome of Pseudomonas syringae.Here,we present a program called EFFECTORSEARCH that synthesizes and extends previous work by allowing users to identify candidate effectors based on any combination of the following five criteria:protein length,proximity to the hrp promoter,n-terminal region,similarity to known effectors,and dissimilarity to housekeeping genes.We demonstrate the utility of the program in allowing users either to search broadly for candidates or to restrict attention to the candidates with the highest confidence in their assignment.
