Objective: To study the protective effects of canthaxanthin against decreasing of i mmuno-function of the acute lung injury induced by lipopolysaccharide in mice and research its possible mechanism for offering scientific basis of its health function. Methods: Randomly distribute 60 male Kunming mices into control group, lipopolysaccharide-induced acute lung injury model group(ALI), dexamethasone (DXM) group (5 mg/kg) and low, middle, high dose groups of canthaxanthin (10 mg/kg, 15 mg/kg, 20 mg/kg). After 30 d feed by different dosage canthaxanthin, control group were given physiological saline, ALI model group, canthaxanthin administrated groups and DXM group were injected with lipopolysaccharide (LPS) (6.0 mg/kg) to induce ALI. Six hours after LPS or physiological saline challenged, abdominal aorta blood for measuring lymphocyte subpopulations(CD3+, CD4+, CD8+), tumour factor-?(TNF-?), leckocyte interpose-8(IL-8), malondialdehyde (MDA) content, superoxide dismutase (SOD), glutathione perioxidase (GSH-Px) activities, and lung wet weight/dry weight ratio, neutrophil MPO activity of lung, tumour factor-?(TNF-?), leckocyte interpose-10 (IL-10) content of lung. Results: Treatment with different dosage canthaxanthin could significantly decrease serum TNF-?, IL-8, MPO, MDA content and lung wet weight/dry weight ratio, while inhibit the reduction of IL-10 in lung and SOD, GSH-Px activities, improve the percent of lymphocyte subpopulations. Conclusion: Canthaxanthin showed protective effects on immuno-function of the acute lung injury induced by LPS in mice.

Proteomics, a new branch of science, has been used to study protein expressions on the molecular level with a dynamic perspective. Organisms under varying states may express different proteins, which results in the set-up of differential proteomics. Research methods of differential proteomics include the separation and identification of proteins. Differential proteomics has a rapid development in recent years. In the study of acupuncture, researchers have reached certain achievements using differential proteomics to investigate the mechanisms of acupuncture treatment for some diseases, including acute spinal cord injury, ischemic cerebrovascular disease, Parkinson's disease and neuralgia.

In recent years, translational medicine, which is characterized by advanced concepts and methods, developes rapidly and playes a strategic role in the development of TCM acupuncture and moxibustion. Therefore, it is worth studying by acupuncturists. Through the background, development, features and research model of translational medicine, the present situation and problems of TCM acupuncture research are analyzed. Several cases of translational Chinese medicine and acupuncture are listed with the consideration of the concept of translational medicine. Studies and thoughts on translational acupuncture are expounded as well. Thus, it is suggested that combined with characteristics of acupuncture, the concept of translational medicine should be utilized to instruct the clinical treatment and research of acupuncture, foster researchers of translational medicine as well as establish the related research teams.

Basic research program is essential to the investigation of the pathogenesis of ocular diseases and the development of novel strategies for the prevention and treatment for these diseases. With increasing support of research grants at various levels, basic research in ophthalmology has gained great achievement in China in recent years. A number of studies have recently been published in well known peer-review international journals and won the State Scientific and Technological Progress Awards. However, we have to keep it in mind that basic research in ophthalmology should be improved qualitatively meanwhile, the imbalance in basic study among different areas needs to be resolved in the near future.

Alzheimer's disease (AD) and other aging-related diseases have become an important public health issue in China. However, current clinical drugs have failed to reverse the pathological process of AD. The holistic approach of traditional Chinese medicine offers advantages in improving cognitive function in AD through multiple molecular pathways, and may have potential for preventing AD. This paper summarizes the effects of classical traditional Chinese medicine and its active components in the improvement of AD-related cognitive dysfunction and describes the functional targets and related molecular mechanisms. This may have significance for the prevention and treatment of AD through multi-target intervention.

Objective To explore the clinical features and operative treatment of floating shoulder injuries. Methods The clinical data of 36 patients with floating shoulder injuries that had been admitted to our hospital from June 1999 to June 2005 were retrospectively analyzed. The scapular neck fractures associated with clavicle fractures were in 31 cases and acromioclavicular joint dislocation in 5 cases. All cases were accompanied by associated injuries, in which rib fractures combined hemopneumothorax and/or lung contusion was 88.9%. The mean time from primary injury to the fracture operation was 9.6 days (range, 3 to 43 days). The clavicle fractures or acromioclavicular joint dislocation were dealt with firstly, then scapular neck fractures treated through modified Judet posterior approach. Thirty-three cases received internal fixation with both injuries of scapular neck and clavicle or acromioclavicular joint and 3 cases received internal fixation only in clavicle shaft. Results All fractures had been restored anatomical reduction in the target site. The mean followed up time was 19.7 months (range, 6 to 69 months). According to Constant and Murley's evaluation, the median score of functional results was 93% (mean 81.3%, range from 9% to 100%). Based on Herscovici's evaluation, 25 (69.4%) cases showed excellent results, 6 (16.7) good, 4 (11.1%) fair, and 1 (2.8%) poor. The recurrence of primary hemopneumothorax was found in 1 case, shoulder joint abduction weakness and subacromial space pain in 3 cases, delayed lesion of suprascapular nerve in 1 case, and posttraumatic shoulder joint instability secondary to arthritis in 1 case postoperation. Conclusion The double injuries with scapular neck and their suspensory device of clavicular shaft or acromioclavicular joint in floating shoulder injuries can hardly be corrected and reduced in three dimensional displacement of distal fracture unit without operation. It is an effective way for such unstable injuries to get good results after open reduction and internal fixation in early stage.

Objective To explore the effects of advanced glyeosylation end products (AGEs) on the binding of hepatic nuclear factors to the human insulin receptor (hlR) gene promoter. Methods The oligonueleotides with hlR gene promoter activity, 42 bp (spanning -1 441 to -1 400, US1) or 146 bp (spanning -638 to -493), were artificially synthesized, with point mutations at 5 key G residues in 42 bp US1 m5 oligonucleotides. US1 and rat hepatic nuclear extracts (HNE) were incubated with glucose 6-phosphate, prior to non-competition and competition gel retardation electrophoresis. Results Competition gel retardation electrophoresis showed that the binding capacity of 32p-labeled US1 probe to HNE could be signifficantly decreased with increased US1. US1-AGEs and US1m5 decreased the binding of probe to HNE as well, but only partly affected the electrophoretie bands [1,5,10 ng US1-AGEs: (41.08±2.86)%, (27.64±2.92)%, (15.35±1.81%) vs (52.05±1.79)%]; 5,10 ng US1m5: (5.20± 1.03)%, (1.81±0.21)% vs (52.05±1.79)%]. AGEs formed on HNE could increase the binding of HNE to probe, along with nonspecifie binding increasing. Conclusion The impact of AGEs on hlR gene expression seems to be related to the effects on cis-elements and trans-acting factors.
