Objective: To analyze the publication activity in traditional Chinese medicine (TCM) and learn more about the development and perspective of TCM as well as its subfields. Methods: TCM-related publications (from 1964 to 2008) indexed in Medline were analyzed, including publication number and proportion of TCM papers, TCM clinical research papers, papers in TCM subfields such as Chinese medicine, Chinese herbs and acupuncture. We also analyzed the journals in which they got published. Results: A total of 34 528 TCM-related papers were indexed in Medline from 1964 to 2008. The number and proportion of publication in Medline were increased steadily. TCM articles have changed towards clinical-oriented research, especially in complementary therapies and acupuncture subfields. Before 1973 the popular content of TCM articles was acupuncture, but at present it changed to Chinese herbs. TCM papers were found in core clinical journals, specialized complementary journals and non-core journals, the last one was the majority. Conclusion: The publication activity of TCM literature increased rapidly since 1970s. TCM attracts more and more attentions and researchers. The safety and efficacy of TCM have been tried to identify by conducting modern scientific researches.

Traditional Chinese medicine (TCM) is an important part of complementary and alternative medicine (CAM) in the world medical market. The basis of globalization of TCM was to make sure the current situation of CAM and the role that TCM plays. It will improve the application and reputation of TCM by analyzing the global usage rate, sort of diseases, social-demographic characteristics of users and medical economics of CAM.

Researches on complementary and alternative medicine (CAM), including traditional Chinese medicine (TCM), are attracting more and more attention in the United States, and their scale and investment are progressively increasing. The differences between China and the United States in application of TCM therapies, background of Eastern and Western knowledge, thinking model, as well as the recognition of TCM theories lead to the differences in content and design of TCM researches.

Objective To evaluate the effects of statins on the cerebral haemodynamics of ischemic stroke patients with transcranial Doppler(TCD). Methods 70 inpatients with acute ischemic stroke were divided into two groups according whether they had taken statins after stroke.The change of the cerebral haemodynamics was studied in the two groups with TCD three months after stroke. Results Three months later,the systolic flow velocities and mean flow velocities of bilateral middle cerebral arteries in the statins groups significantly increased (P＜0.05). The pulse index of bilateral middle cerebral arteries in statins group significantly decreased (P＜0.05).The flow velocities and pulse index of bilateral middle cerebral arteries in control group don't change significantly(P＞0.05). Conclusions Statins may have the effects of improving the situation of cerebral haemodynamics of patients with ischemic stroke.

Objective To analyze the causes of peripherally inserted central catheter (PICC) relat-ed infections, study the types of pathogens and their drug sensitivities in order to supply evidence for clini-cal medication. Methods 110 cancer patients were analyzed for PICC related infections and blood sam-pies underwent bacterial culture. Results Of 110 cases of cancer patients, catheter-related infections were found in 11 patients (10.00%), including 9 cases of local infection (8.18%), and 2 cases of hemato-ge-nous infection (1.82%). Catheter-related infections were not associated with gender, age, types of catheter, venous selection, and the inserted length of intravenous catheter. Catheter- related infections were likely to be associated with the indwelling time of catheters. Conclusions To avoid the infections related to long-term PICC, strict aseptic operation and standardized maintaining procedures are required.

OBJECTIVE To discuss the antibiotic resistance situation of Pseudomonas aeruginosa and provide basis for therapy and control of the nosocomical infection. METHODS Fourteen strains of P.aeruginosa which derived from 60 and more years aged patients in intensive care unit(ICU) were analyzed by conventional chemistry test,PCR inspection,antimicrobial susceptibility test,plasmid pattern analysis and enterobacterial repetitive intergenic consensus(ERIC)-PCR polymorphism analysis. RESULTS Fourteen strains had the same chemistry traits,many strains appeared multi-antibiotic resistance,10 strains had a plasmid of 23kb or so without obvious association with(multi-antibiotic) resistance,14 strains were divided into three clusters by ERIC-PCR technique and their banding pattern cluster analysis,their similarity coefficients were from 0.62 to 0.86. CONCLUSIONS Nosocomial infection of P.aeruginosa which screened from aged patients in ICU has taken on sporadic state;ERIC-PCR fingerprinting technique genotyping method has high discrimination,and good reproducibility and give faster genotyping result with less hands-on time,which serves as nosocomial infection epidemiologic surveillances of P.aeruginosa.
