This article found that the actual situation about humanities education of medical postgraduates is not optimistic through investigation of the situation on humanities education of the postgraduates in Zunyi Medical College. Some prominent problems existed. This article also proposed some practical suggestions to solve the problems based on the analysis of this phenomenon, so as to improve the humanities education of medical postgraduates and cultivate postgraduates to be medical workers with full humanistic care.

Laparoscopic surgery for gastrointestinal diseases had a remarkable progress in the past 20 years. Laparoscopic surgery for colon cancer is adopted worldwide by increasingly surgeons based on the evidence from randomized controlled studies. Minimally invasive surgery is also adopted as alternative procedure for early gastric cancer. The standardization and spreading of the minimally invasive technique for gastrointestinal surgery is also being implemented efficiently in China. However, how to innovate the new technique and improve the new instrumentation for minimally invasive surgery is still a problem which we have to confront in the current situation. But we believe that with the great efforts of gastrointestinal surgeons, the widespread adoption of minimally invasive gastrointestinal surgery would surely take place in the near future.

The defense mechinism of heat shock protein(HSP)acting as moleculars chaperons requires heat shock transcription factors as the primary mediators of the heat shock response.Increased expression of HSP may protect the heart.Overexpression of HSP can inhibit cardiomyocyte apoptosis,protect the integrity of the microtubules and the actin cytoskeleton in cardiac myocytes and endothelial cells exposed to ischemia,participate in the folding and activation of protein kinases and transcription factors such as HIF-1? and HSF1,bind to endothelial nitric oxide synthase(Enos) and stimulate its activity,and downregulate cytokine production.Hence,it is of benefit to efficiently elevate HSP expression in myocardium using pharmacological and/or gene therapy procedures without any adverse effect.

AIM: To evaluate the role of the meso-hippocampal dopaminergic systems in the generation of hippocampal P300-like potentials. METHODS: Changes of ventral hippocampal P300-like potentials were examined after lesions of the meso-hippocampal dopaminergic systems.The extracellular DA and DOPAC were collected by the push-pull method in the ventral and dorsal hippocampus and their contents were measured by high-performance liquid chromatography with electrochemical detection(HPLC-EC). RESULTS: The contents of DA and DOPAC in the ventral hippocampus were higher than those in the dorsal hippocampus in the normal animals. The peak latencies of P300-like potentials were prolonged and the contents of DA and DOPAC decreased in the ventral hippocampi after lesions of the meso-hippocampal dopaminergic systems. CONCLUSIONS: There exist meso-hippocampal dopaminergic systems in rats;The meso-hippocampal dopaminergic terminals is mainly located in the ventral hippocampal area in rats; The meso-hippocampal dopaminergic projections take part in the generation of the hippocampal P300-like potentials in rats.

OBJECTIVE:To evaluate the feasibility of preparing tretinoin liposome by calcium acetate gradient method and to compare this method with the microfilm and the antiphase evaporation method.METHODS:Tretinoin liposome was pre-pared by microfilm method,antiphase evaporation method and calcium acetate gradient method,respectively.Sephadex G-50was used for isolation and ultraviolet spectrophotometry was utilized to determine the entrapped efficiency and grain size of liposomal tretinoin.Electronmicroscope was applied to observe the shape of tretinoin liposome.RESULTS:The calcium ac-etate gradient technology achieved the highest entrapped efficiency of90.48%.The liposomes had perfect shape with the mean diameter of35.8nm and kept stable in quality at4℃for3months.CONCLUSION:The liposome with high entrapped effi-ciency could be prepared by calcium acetate gradient method,and the method is feasible.

Objective To evaluate the academic quality and characteristics of edition of the Chinese Journal of Geriatrics. Methods Within the database of Chinese Medical Citation Index(CMCI), the citation analysis was used to analyze the number and its distribution of the cited original articles published in the Journal 1999-2004. Results The average freguency for a single article cited by other researchers was 2.82, and there were more articles cited than other journals. The authors of these articles were distributed in the 30 province and municipalities, among which Beijing, Guangdong Province, Shanghai were in the front of Geriatrics research. There were 514 cited journals, and self-citing rate was 6.07%. Conclusions The Chinese Journal of Geriatrics has published high quality articles, and has its own edition characteristics to keep its steady level of research. It is one of the most important information resources for the geriatrics researchers and one of the most important medical journal.
