This paper reviewed the researches of TCM syndromes of rheumatoid arthritis in the past four years.The author believed that more and deeper epidemiological surveys are needed for studying rheumatoid arthritis and hence to improve its clinical effects.

Objective:To investigate the application valve of bFGF to improve the viability of subdermal vascular network flap.Methods:Four white healthy pigs were used,each pig had 6 SVNF on back,16cm?4cm,totally 24 flaps were divided randomly into 2 groups:The bFGF groups and the control groups.On postoperative day 6,we observed the appearance of the flaps.The survival area of each flap was measured and the flap was harvested for histological analysis and the density of angiogenesis was also examined.Results:On postoperative day 6,the survival rates of the bFGF group and the control group were (81.2?1.7)% and (66.2?1.8)% respectively,the angiogenesis density of the middle and the distal segment in the bFGF group was (16.7?6.0)/mm2,(29.7?5.5)/mm2,(14.9?6.0)/mm2 respectively,while (16.6?4.0)/mm2,(21.4?5.2)/mm2,(3.5?5.1)/mm2 respectively in the control group.The bFGF group was superior to the control group in the appearance and histological analysis of the flaps.Conclusion:The results suggest that the injection of bFGF locally can promote the survival rate by accelerating the blood circulation of the SVNF’ bottom and edge,shorten the division time of SVNF and broaden the ratio of length and width.
