Objective To further explore the relationship of CEA in gastric cancer tissue expression and serum levels,and seek after the prediction effect of serum CEA in the peritoneal metastasis.Methods Retrospective analysis of 38 gastric cancer patients with peritoneal metastasis (group A) and 60 gastric cancer patients without peritoneal mnetastasis (group B),and analyze the first time in two groups of patients with preoperative serum CEA levels.The expression levels of CEA was examined by Immunohistochemistry method in primary tumors、negative margin and peritoneal metastases foci from group A and in primary tumors from group A,and the detection result of the statistical was analyzed.Results The expression of the first preoperative CEA serum levels in group A and group B was 73.68％ and 41.67％ respectively (x2 =9.604,P =0.002),and the two groups of patients with the first preoperative CEA serum levels was (74.00 + 6.00) ng/mL,(46.06 + 9.03) ng/mL,The two groups was statistically significant (t =4.715,P ＜0.01).In group A,the expression of CEA of primary tumors was higher than that of negative margins (x2 =29.587,P =0.000);the difference expression of CEA positive degree in gastric cancer primary tumors and negative margins was statistically significant(Z =-5.348,P =0.000).In peritoneal metastases foci the expression of CEA was 92.11％,that was 64.82％ in primary tumor(x2 =6.728,P =0.009);the difference expression of CEA positive degree in peritoneal metastases foci and primary tumors was statistically significant (Z =-5.397,P =0.017).In primary tumors,the expression of CEA in group A and group B was 68.42％ and 42.67％ respectively (x2 =4.450,P =0.035),the two groups of patients with the difference expression of CEA positive degree was statistically significant,the two groups was statistically significant(Z =-2.227,P =0.026).Conclusion Over expression of CEA might have a critical role in peritoneal metastases of gastric carcinoma.The differences of the expression of CEA in gastric cancer in different tissues may indicate the risk of gastric cancer peritoneal metastasis.

Large number of TCM ancient books, the literature, has a long history and complicated contents, including the principles, methods, prescriptions, medicines and other various aspects. How to obtain and make use of knowledge in ancient books, we must establish a set of relatively precise knowledge and semantic relation networks. Knowledge yun performing reasonable rebuilding of TCM literature, containing much TCM knowledge and information, will be an important way for knowledge findings.

Traditional knowledge digital Library (TKDL) is a mature database for protection of traditional knowledge from illicit aggression, and also used for searching and examining the novelty and inventive step of applied inventions. TKDL has the role of defensive protection on Indian traditional medicine through promoting legislation initiatively, signing TKDL access agreement with international intellectual property authorities, and establishing close cooperation with WIPO. TKDL is a typical and successful case. Based on the publication and promotion ways of traditional knowledge digital library and the actual national condition in China, this paper proposes several applicable ways for publication and promotion of traditional knowledge protection directory of traditional Chinese medicine database.

To study the initiatives and progress of African nations in promoting the development of traditional medicine to determine if these measures can be applied to the protection of traditional Chinese medicine knowledge. Information research methods were used to collect and analyze relevant literature. The development of African traditional medicine has been effectively promoted through various measures taken by African organizations and governments. In recent years, Africa has achieved remarkable results in promoting the development of traditional medicine. Many other countries will benefit from studying their examples and adopting similar measures.

Chinese medical thesaurus was constructed setting knowledge element as the core and knowledge classification as the basis. In making the full use of our previous traditional knowledge classification research on traditional knowledge protection of TCM, the ancient literature of TCM knowledge classification system was constructed. The construction of TCM ancient books thesaurus plays a vital role in ancient Chinese medicine resource description, intelligent retrieval and knowledge discovery. This article disscussed the necessity of constructing Chinese medical thesaurus and the problems need to pay attention to in the process of building from three points of the Chinese medical thesaurus construction idea, plan, and the relevant system construction.

By reviewing the selection principle and evaluation criterion on the periodicals in the well-known evaluation and index system of China and abroad, the article provides both the related information for researchers to get a general idea of this system and the criterion for periodicals to join the system.

Objective To explore the preventive effect of Cefradine plus heparin sealing catheters on central center venous (CVC)catheter-related infections.Methods One hundred and twelve patients with central venous catheter were randomly divided into control group(n=57)and intervention group(n=55).In the control group,heparin sodium was used to seal the catheters and in the intervention group Cefradine plus heparin were used.The two groups were compared in terms of central venous catheter(CVC)-related infections.Results The CVC-related infection rates are 12.28%and 0%in the control and intervention groups respectively, with statistical difference between them(P<0.01).Conclusions Cefazodine and heparin used to seal the catheters in the treatment of patients with central venous catheter can effectively reduce incidence of catheter-related infections.

The quarantine inspection and acceptance of laboratory animals is an important work, which can protect animals from pollution, occurrence and spread of diseases in the surounding area, and it is the key point to realize the quality standardization of laboratory animals.Beagle dogs are acknowledged widely as specialized laboratory dogs which is widely employed in experiments of drug safety evaluation because of the good genetic stability, environmental adaptability, disease resistance and consistency testing in the experiments.Establishment of standard operating procedures of beagle dog quarantine acceptance check for drug GLP organization tests, refining technical points, strengthen the technical training of quarantine officers, and efforts to improve the level of quarantine are needed to finally ensure the quality of laboratory animals.

The normative research on safeguarding intangible cultural heritage of traditional Chinese medicine is the important measure after building list and filing work of Convention of the protection of intangible cultural heritage of UNESCO, and also a strategy in accordance with the principle of the protection of traditional knowledge of traditional Chinese medicine.This article discussed the arrangement and standardization in the academic level of folk medicine technology teaching orally from generation to generation, to provide protection for the living inheritance of intangible cultural heritage of traditional Chinese medicine, and a pilot measure for the construction of intangible cultural heritage protection system.
