Exploration and Thinking of Literature Research on Ancient Books of Traditional Chinese Medicine / 中国实验方剂学杂志

Literature research on ancient books of traditional Chinese medicine （TCM） is an important carrier for inheriting the academic achievements and thoughts of TCM， and a key step for continuing the Chinese civilization and realizing the great rejuvenation of the Chinese nation. Based on this， the paper puts forward the purpose of sorting out TCM ancient books：to explore the treasure of traditional culture， reveal its significance， carry forward its spirit， learn from its experiences， so as to make a contribution to the development of TCM. And this paper expounds several major problems in the literature research， that is， paying attention to the phenomenon of "stubborn bass"， avoiding the trend of "latecomers turning inferior"， attaching importance to the hidden trouble of "making comments on behalf of the ancients". Then， this paper discusses the methodology of carrying out accurate research and revealing the true nature and true value of scholarship with the idea of confucian orthodoxy， the rules of not forgetting the original intention and the scientific method. Taking the materia medica archaeology as an example， the author shared the practical exploration of how to crack the historical code with scientific and technological means， so as to provide useful reference for the literature research on TCM ancient books.

Genetic and Epigenetic Alterations in Bladder Cancer / 대한배뇨장애요실금학회지

Bladder cancer is one of the most common cancers worldwide, with a high rate of recurrence and poor outcomes as a result of relapse. Bladder cancer patients require lifelong invasive monitoring and treatment, making bladder cancer one of the most expensive malignancies. Lines of evidence increasingly point to distinct genetic and epigenetic alteration patterns in bladder cancer, even between the different stages and grades of disease. In addition, genetic and epigenetic alterations have been demonstrated to play important roles during bladder tumorigenesis. This review will focus on bladder cancer-associated genomic and epigenomic alterations, which are common in bladder cancer and provide potential diagnostic markers and therapeutic targets for bladder cancer treatment.

<p><b>OBJECTIVE</b>To determine the differentially expressed serum proteins in patients with hepatoma carcinoma and identify a putative diagnostic marker.</p><p><b>METHOD</b>The isobaric tags for relative and absolute quantitation (iTRAQ) labeling method and LC-MALDI-TOF/TOF MS detection method were used to quantify serum proteins in hepatocellular carcinoma patients (n =20) and healthy individuals (n =20). Real-time reverse transcription-polymerase chain reaction was used to verify the differentially expressed proteins by analyzing the corresponding mRNA expression levels in the hepatic carcinoma and healthy hepatocyte samples, as well as in 30 pairs of patient-matched hepatic carcinoma and adjacent normal tissue samples. Western blot analysis was used to verify the protein expression in hepatic carcinoma cells.</p><p><b>RESULT</b>Fifty-one proteins were significantly differentially expressed between the hepatic carcinoma group and healthy controls. The iTRAQ protein profile showed that the serum level of clusterin was significantly lower in hepatoma carcinoma patients. The mRNA level of clusterin was 20-fold lower in hepatic carcinoma cells than in healthy hepatocytes, and was 2.38-fold lower in hepatoma tissues than that in adjacent normal tissues. The clusterin protein levels were significantly lower in hepatic carcinoma cells (8.06 vs normal hepatocytes: 27.81; P less than 0.01).</p><p><b>CONCLUSION</b>The serum expression of clusterin is significantly decreased in both serum and tissues of hepatic carcinoma patients. The relationship between hepatic carcinoma and clusterin should be evaluated in future studies.</p>
