1.Metabolic syndrome and hepatocellular carcinoma:an advance in epidemiology study
Academic Journal of Second Military Medical University 1981;0(04):-
Hepatocellular carcinoma(HCC) is the fifth most common cancer and the third cause of cancer-related death worldwide;meanwhile,it is also one of the fastest growing malignancies.The causes of HCC are multiple;HBV is the most important cause in China,with about 25%-30% of HBV infection patients finally develop hepatic cirrhosis and liver cancer.At present,large scale epidemiological studies revealed that the metabolic syndrome(MS) was closely related to liver cancer,and it even served as an independent risk factor for the occurrence and progression of liver cancer.Non-alcoholic fatty liver disease is a metabolic syndrome clinically manifested in the liver;recently it has been indicated to be closely related with HCC development and progression.This paper reviews the recent researches on metabolic syndrome and liver cancer,so as to provide literature for preventive and therapeutic studies on non-virus-related liver cancer.
2.Updates on the relationship between vitamin D and epilepsy
International Journal of Pediatrics 2016;43(12):948-952
Vitamin D adjusts the body′s absorption and utilization of calciumand phosphorus. Vitamin D deficiency is closely related to incidence of many disease. Several disorders,both systemic and those of the nerv-ous system,have been linked with vitamin D deficiency. Neurological disorders with a vitamin D link include but are not limited to multiple sclerosis,Alzheimer and Parkinson disease,as well as cerebrovascular disorders. In re-cent years,studies have found that the vitamin D may play a critical role in the pathogenesis of epilepsy and pos-sess certain anticonvulsant effects. This article summarized the role of vitamin D in the nervous system and epi-lepsy,the level of serum vitamin D and the correlation of the polymorphism of its receptor genes with epilepsy. The review also summarizes the interaction between antiepileptic drugs and vitamin D.

Histone acetyltransferases (HATs) are involved in the regulation of gene transcription in eukaryotic cells and their inhibitors could be a promising class of drugs due to their ability to modulate transcription and exert antiviral, anti-inflammatory as well as antioxidant effects. Nonradioactive spectrophotometric HAT assay is an alternative method to the widespread radioactive assay but suffers from drawbacks as lack of sensitivity and accuracy. A simple, non-radioactive fluorescent assay that measures the production of CoASH was established by its facile reaction with O-phthalaldehyde and 2-amino-ethanol. This method gives much higher accuracy compared to spectrophotometric assay, and allows screening of various compounds with potential HAT inhibition. The novel assay should be a valuable tool in transcriptional research and especially drug discovery.
