Objective To evaluate simple and practical methods to repair deep wounds in the foot near the ankle joint.Methods 128cases of deep wounds near ankle jo int with exposed bone and tendons fro mJan 1990to Jan 2002were reviewed .Altogether 13types of microsurgical flaps were applied in these cases and obtained satisfactory results.Timing of sur gery:53cases of primary repair,28c ases of secondary repair,47cases of delayed repair.Results26cases of reverse skin avultion were repaired by venous anastomosis in a valsed flaps,of which19survived completely,and 7underg one partial necrosis.There were 19f ree tissue flap grafts in which 13sur vived,3failed and 3undergone partial necrosis and infection.All pedicle tissue flap grafts amounted to 83cases wi th only3partial necrosis in 58cases of sura l nerve flaps graft,and 1total necro sis in 25other types of flap grafts.Con-clusion Sural nerve flaps graft is a reliable method to repair deep wounds with exp osed bone and tendons near the ankle joint.It is easy to perform with excellent abrasion resistance and little effect on the donor limb.

Objective To investigate the relationship of the cytogenetic abnormalities detected by FISH in patients with MM and their clinical features. Methods FISH on bone marrow (BM) cells was performed in 57 enrolled MM patients. Relationships between cytogenetic abnormalities and clinical features were analyzed. Results By statistical analysis , both D13S319 deletion and RB1 deletion were associated with high level of serum LDH (P = 0.024; P = 0.018) and BM plasma cells index (P = 0.027; P = 0.013). 1q21 amplification was significantly associated with high level of LDH (P = 0.030 ) and the occurence of light chain type myeloma (P = 0.023). IgH rearrangement was associated with renal function damage (P = 0.009). There were correlations among D13S319 deletion, RB1 deletion, 1q21 amplification and IgH rearrangement (P<0.01). Conclusion The genetic abnormalities detected by FISH in patients with MM were correlated with various clinical poor prognostic indicators, which can evaluate the condition and prognosis of patients more efficiently.
