Objective To evaluate the academic level and the popularity of Chinese Journal of Orthopaedics from the point view of citation. Methods According to the information of Chinese Medical Citation Index (CMCI), the amount and distribution of the original articles in Chinese Journal of Orthopaedics cited by the journals included by CMCI were statistically analyzed. The data analysis included the percentage of cited articles, the number of citation of a single article, authors of most cited articles, geological regions of cited articles, citing journals, the self citing rate and years of citation. Results The percentage of cited papers (663 articles, 3728 times) in all published 1 182 articles in Chinese Journal of Orthopaedics from 2005 to 2009 was an average of 56.09%. The average time of original articles cited by other researchers was 5.62. The highest one was citated by 104 times. 210 articles (31.68% of total papers) were cited 5 or more times, and the all cited times from them were 2835 (76.04% of total cited times). 663 cited articles were written by 485 authors from different countries. The most frequently cited author wrote 12 papers. The number of authors with one paper cited was 386 (79.58% of total authors). The cited authors are from the mainland, HongKong, and Taiwan in China, as well as USA, Canada, France. Beijing, Shanghai and Tianjin are leading cities in orthopaedic research. Beijing was the first place (32.16% of total authors). There were 445 citing journals. There was 217 items self cited; the self- citing rate is 0.058. Conclusion Chinese Journal of Orthopaedics has provided high quality articles and has a strong influence in the field of medical research. It has been become an important resource for orthopaedic researchers and a vital medical journal in China.

Objective To evaluate the relationship between serum albumin(Alb) level and short-term prognosis in patients with acute cerebral stroke.Methods The serum Alb level was examined at admission and once in two weeks during hospitalization in 242 patients with acute cerebral stroke.The mortality,incidence of complication and rate of disease improvement were compared between lower serum Alb level group (Alb

Objective To investigate the changes of coagulation and fibrinolysis systems in patients with solid cancer. Determine the mechanism of thrombosis formation in solid cancer and the the metastasis mechanism of solid cancer.Methods To measure plasma concentrations of TF,TFPI,t-PA,u-PA,PAI-1 by ELISA and test protein C activity(PC:A)by chromogenic substrate assay.Results Plasma concentrations of TF,TFPI,u-PA,PAI-1 were all higher in solid cancer patients than normal control and higher in metasta- sized team than non-metastasized team.In the dead team,u-PA and PAI-1 were higher while TFPI was low- er. t-PA was higher in cancer patients combined with venous thromboembolism while protein C activity was lower.Conclusion Disorders of coagulation and fibrinolysis system are related to the thrombosis formation in solid cancer.Coagulation and fibrinolysis factors take part in the metastasis progress of solid cancer. High concentration of u-PA and PAI-1 or low concentration of TFPI are considered to be related with poor outcome.

Objective To investigate the effects of exogenous fragile histidine triad(FHIT) gene on apoptosis of human glioma cell line U87. Methods By the method of liposome transfection,plasmids pcDNA3.1/myc-His(-)B-FHIT and pcDNA3.1/myc-His(-)B were transfected into glioma cell line U87.U87 cells were divided into three groups: U87-FHIT group,U87 cells transfected by plasmids pcDNA3.1/myc-His(-)B-FHIT;U87-vector group,U87 cells transfected by plasmids pcDNA3.1/myc-His(-)B;and blank control group,U87 cells without transfection.The expression of exogenous FHIT protein was detected by Western blot and immunofluorescence staining.The effects of FHIT on the growth characteristics of U87 were observed by MTT and flow cytometry. Results Growth inhibitory rate and apoptosis rate of the cells in U87-FHIT group were significantly higher than those in U87-vector group and blank control group(P

Fragile histidine triad(FHIT) gene is a tumor suppressor gene that locates on chromosome 3p14.2.FHIT can induce cell apoptosis and inhibit cell growth by activating caspase,inhibiting PI3K-Akt-survivin signal pathway and phosphorylation of I?B-?,and binding with microtube.The inactivation of FHIT is closely related with carcinogenesis.The advances in research on the structure,biological function,relationship between inactivation and carcinogenesis,and gene therapy of FHIT are reviewed in this paper.

Cerebral arteriovenous malformation is a common cerebrovascular disease.Its exact pathogenesis remains unclear.At present,it is thought that this disease is caused by kinds of factors,including congenital and acquired factors.

BACKGROUND:Porous tantalum with high porosity, low elastic modulus, high friction coefficient has stable biological characters and good biocompatibility, which is considered as an ideal implant material in orthopedic surgery. OBJECTIVE:To review the application situation of porous tantalum used in artificial joints, spine, bone necrosis, defects of bone and so on. METHODS:A computer-based search of PubMed, Wanfang, and VIP databases was performed for relevant articles published from 1990 to 2014 using the keywords of “porous tantalum, biological character, orthopedic applications” in English and Chinese. RESULTS AND CONCLUSION:Porous tantalum is a kind of good orthopedic implant material, with high porosity, low elastic modulus, high friction coefficient, and good compatibility. Porous tantalum is mostly used in the preparation of integrated acetabular cup, total hip arthroplasty acetabular cup, acetabular reinforcing pad, porous tantalum metal rod, tibial plateau prosthesis, patelar prosthesis and tibial plateau prosthesis, which has achieved good clinical effects.

Objective To provide the evidence for working out the strategies for library service by investigating the characteristics of Internet users' information behaviors in medical college and university library. Methods The In-ternet users' information behaviors in electronic reading room of medical college and university library were recorded using management software and analyzed using the SPSS. Results Medical undergraduates were the major readers in electronic reading room of medical college and university library. Their Internet information behaviors were charac-terized by information searching which accounted for 55. 19%. The use of foreign databases, especially PubMed, was more than that of domestic databases. The time of readers to search and use information was centralized in their working hours. Conclusion Library should help its readers to know how to search the databases, how to make full use of Internet resources, and how to improve their learning efficiency in order to make sure that the readers can ef-fectively search and use the Internet information.
