Orthopedic Journal of China 2006;0(17):-
[Objective] To measure the patella thickness and to investigate the techniques and safety of patella resurfacing during total knee arthroplasty in Chinese patients with rheumatoid arthritis.[Methods]From Jan.2005 to Jan.2006,the maximal and minimum thickness of the patella,the preserved thickness of bony patella after resurfacing and the total thickness of patella composite after patella replacement in 95 consecutive total knee arthroplasty for rheumatoid arthritis were measured.The patients were followed-up after operation,anterior knee pain and patella fracture were recorded.[Results]1)The mean maximal thickness before resurfacing was(22.01?1.64)mm(range,18~26 mm),the mean minimum thickness before resurfacing was(11.69?2.33)mm(range,6~16mm).2)The mean thickness of preserved bony patellar thickness was(13.23?0.96)mm,(range,11~16 mm),including 11 mm in 4 knees(4.2%),12 mm in 15 knees(12.7%),13 mm in 38 knees(40%),14 mm in 32 knees(33.7%),15 mm in 5 knees(5.3%)and 16 mm in 1 knee(1.1%).The mean thickness of the patella composite was 21.42 mm(range,20~25 mm),the thickness of resurfaced patella was equal to or thinner than the preoperative patellar thickness in 86 knees(90.5%).Anterior knee pain was found in 3 knees,but no patellar fracture or component loosening occurred.[Conclusion]1)The patellar thickness in rheumatoid arthritis is thinner than the thickness in normal patella.2)It is a safe option to retain bony patella thickness at 12~14 mm during patellar resurfacing in Chinese adults with rheumatoid arthritis.3)Patellar resurfacing in patients with rheumatoid arthritis has a good result in a short term.Careful attention to good surgical technique in component alignment and patellar resurfacing is crucial to obtain good results.
2.The interrelationship between the severity of periodontitis and changes in the human dental pulp
Chinese Journal of Pathophysiology 1986;0(03):-
In order to analyze the association of the periodontitis severity withchanges of the human dental pulp, one hundred caries-free and restoration-free periodontallyinvolved teeth with different periodontic destruction were studied histologically. It wasfound that there was correlation between the severity of periodontitis and changes in thehuman dental pulp. The incidence of pulpal pathosis rose as the periodontic destructionbecame severe. Pulpal inflammation was related to periodontitis, but not to the severityof periodontitis. Pulpal necrosis was mostly found in the teeth with advanced periodonti-tis.

Distribution channel of Chinese herbal medicines has been changing. From Han to Ming Dynasty, Chinese herbal medicine were mainly trafficked to urban by dealers or farmers; From the Ming Dynasty to the foundation of new China, distribution channels are primarily intermediated with township "bazaar" and national distribution center with fixed place and regularly trading hours. In the planned economy period, the state-owned herbal medicine company was the sole medium with monopoly nature. From the mid1980s to the end of last century, planned economy and market economy have been co-existing. Stepping into 21st century, producing area highlighted in the distribution channels. Presence or absence and rise or fall of different types of distribution market went throughout the changing process of distribution channels, which became an important clue. Changes were motivated by economical consideration of channel subject, which originated from commodity characteristic and social environment changes.

Objective To observe any effects of pulsed electromagnetic fields (PEMFs) on the expression of transforming growth factor beta-1 (TGF-β1) after sciatic nerve injury and to investigate the possible mechanism of any regeneration of the injured sciatic nerve.MethodsForty-eight SD rats were randomly divided into a PEMF treatment group,a model group and a normal control group with 16 rats in each group.The three groups were then sub-divided into 1 day,3 day,7 day and 14 day subgroups.The rats of the model and treatment groups were clamped to produce a sciatic nerve injury model.The treatment sub groups were exposed to a 9 mT PEMF at 14 Hz for 2 hours once daily for 1,3,7 and 14 days,respectively.The model group was given sham exposure and the normal control group was reared conventionally and not given any special treatment.The histological changes in the rats' sciatic nerves were observed under a light microscope after hematoxylin-eosin staining.Expression of TGF-β1 was detected by immunohistochemical methods.ResultsAfter 7 and 14 days of treatment,Wallerian degeneration of the sciatic nerve in the treatment group was more obvious than in the model group.The expression of TGF-β1 increased during the treatment process and reached a maximum at the 14th day after nerve injury.The expression of TGF-β1 had increased significantly in the model and treatment groups compared with the control group at all observation time points.At the 3rd,7th and 14th day after the operation,the expression of TGF-β1 in the treatment group was significantly higher than that in the model group. Conclusion PEMFs can accelerate Wallerian degeneration of peripheral nerves and can up-regulate the expression of TGF-β1 after sciatic nerve injury,at least in rats.
