Objective: To analyze the clinical characteristics, pathological features and survival of patients with AIDS related non-Hodgkin’s lymphoma (ARL) . Methods: The clinical data of 53 ARL cases diagnosed and received care at Zhongnan hospital of Wuhan University were retrospectively studied, and 106 controls were enrolled as control group according to 1∶2 for paired cases and control. SPSS 13.0 package was used for statistical analysis. Kaplan-Meier was applied to assess the survival probability. Results: The mean age of patients with ARL was 43 (11-67) years. Male versus female was approximately 4∶1. The median CD4⁺ T cell count was (146±20) /ml. The Ann Arbor clinical classification showed that 52.8% of the cases were of stage Ⅲ and Ⅳ. Approximately 54.7% of the patients had elevated serum lactate dehydrogenase (LDH) . According to international prognosis index score, 64.2% of the patients were in high risk group. Diffuse large B-cell lymphoma (DLBCL) was the predominant histological subtype. Among 53 cases, 33 cases (62.3%) received combination of anti-HIV therapy and anti-NHL (CHOP) chemotherapy regimen, 8 cases (15.1%) only received anti-HIV therapy, and 12 cases (22.6%) asked for alleviative treatment. Median survival time was (6.0±1.3) months for ARL cases versus (48.0±10.0) months for controls (P<0.05) . After eliminating cases who did not receive anti-lymphoma treatment, ARL cases showed a lower 1-year OS rates than control group (60.6% versus 83.0%) , but no difference about 2-, 3- and 5-year OS rates (53.5% versus 60.5%, 48.1% versus 45.9%, and 39.1% versus 27.5%, respectively) . Conclusions ARL is more common in young adults; one-year mortality rate is high. Anti-HIV therapy combined with anti-NHL therapy could significantly improve the prognosis of ARL patients. CHOP regimen may be more suitable for ARL patients.

Objective: To investigate clinical effects of middle and low peroneal artery perforator flap with pedicle on repairing skin and soft tissue defects of ankle. Methods: Twenty patients with skin and soft tissue defects of ankle and exposure of tendon and bone were admitted in our burn wards from April 2012 to December 2015. The size of skin and soft tissue defects ranged from 5 cm×4 cm to 23 cm×10 cm. Patients were treated with debridement and vacuum sealing drainage (VSD) after admission. After VSD treatment for 1 week, flap transplantation operation was performed. Middle and low perforating branches of peroneal artery were detected by portable Doppler blood flow meter before the operation. Flaps were designed and resected according wounds during the operation, with 1 or 2 middle and low perforating branches of peroneal artery in flaps. Seventeen patients were treated with middle and low peroneal artery perforator flap. Larger wounds with exposure of tendon and bone were repaired with middle and low peroneal artery perforator flap, and the other wounds were repaired with intermediate split-thickness skin graft of thigh on the same side in three patients. The size of flap ranged from 6 cm×5 cm to 25 cm×12 cm. The donor sites were sutured directly or repaired with intermediate split-thickness skin graft of thigh on the same side. Results: After operation, 1 patient with partial skin necrosis at the distal of the flap because of disorder of venous circulation healed after dressing change and physiotherapy, and flaps of the other 19 patients survived well. During follow-up of 3 to 36 months, flaps of all patients were in good appearance, with no obvious cicatrix, and the affected limbs and ankle joints functioned well. Conclusions Middle and low peroneal artery perforator flap with advantages of stable perforating branch, reliable blood supply, and large resected size, can repair skin and soft tissue defects of ankle.

OBJECTIVETo explore the curative effect of reverse bi-pedicle posterior interosseous artery perforator flap in repairing skin and soft tissue defects on the wrist.

METHODSSeven patients with soft tissue defects on the wrist, including simple skin and soft tissue defects in 4 cases and skin and soft tissue defects combined with radial tendon injury in 3 cases, were hospitalized from December 2010 to March 2012. The area of skin defect on the volar side of the wrist ranged from 4.8 cm x 4.0 cm to 6.2 cm x 4.5 cm, while that on the dorsal side ranged from 3.5 cm x 3.2 cm to 6. 5 cm x 5.4 cm. These wounds were respectively caused by traffic injury (3 cases), reamer injury (2 cases), burn (1 case), and tumor resection (1 case). Reverse bi-pedicle posterior interosseous artery perforator flaps were used to repair these defects, with area of one pedicle ranging from 2.5 cm x 2.0 cm to 3.5 cm x 2.5 cm and the area of the other pedicle ranging from 2.5 cm x 2.5 cm to 4.0 cm x 3.0 cm. The donor sites were closed by suturing.
