Assessing the evolution of scientific publications in orthopedics journals from mainland China, Hong Kong, and Taiwan: a 12-year survey of the literature.

Background: In China, the field of orthopedics has experienced significant growth over the past 12 years. However, the recent status of research on orthopedics among individuals in mainland China, Hong Kong, and Taiwan is unknown. In this study, we investigated characteristics and trends of orthopedics publications from these three regions.

[The screening and identification of Apolipoprotein A-II from serum differential proteins in hepatocellular carcinoma patients].

Objectives: To screen differential proteins in serum from hepatocellular carcinoma (HCC) patients by Proteomic Technology and to purify and identify them.

Methods: Surface enhanced laser desorption Ionization time of flight-mass spectrum (SELDI-TOF-MS) was employed to screen differential proteins in serum from 33 HCC patients and 33 control cases, and then to purify and identify them using isoelectric precipitation, Tricine sodium dodecyl sulphate polyacrylamide gel electrophoresis (Tricine-SDS-PAGE) and high performance liquid chromatography tandem Mass Spectrum (HPLC-MS).

Results: 65 protein peaks in the range of relative molecular weight from 2,000 to 10,000 were found significant difference (P less than 0.
