Repairing soft tissue defect coverage in lower leg with a bridge shaped medial hemisleus muscle flap transplantation / 中国骨伤

<p><b>OBJECTIVE</b>To summarize clinical application results of repairing soft tissue defect in lower leg with a bridge shaped medial hemisleus muscle flap pedicle transplantation.</p><p><b>METHODS</b>From January 2008 to January 2012,12 patients with soft-tissue defect in lower leg underwent reconstruction with a bridge shaped medial hemisleus muscle flap pedicle transplantation. There were 8 males and 4 females with an average age of 34 years old ranging from 22 to 50 years old. Time after injury was from 2 to 12 weeks (means, 3.5 weeks ). The immediate coverage of the muscle flaps were performed by a meshed split-thickness skin graft. The donor site was closed directly.</p><p><b>RESULTS</b>All the muscle flaps had survived completely. Follow-up period ranged form 1.8 to 4.0 years (means, 2.8 years) postoperatively. The tibia and fibula fractures were confirmed healing. A good contour was confirmed at the recipient area. The results were evaluated with LEM questionnaire, excellent results were obtained in 6 cases, good in 5 cases and fair in 1 case. Satisfactory clinical results were obtained in 11 cases.</p><p><b>CONCLUSION</b>This technique is particularly useful for repairing soft tissue defect in the injured leg when only one vessel remains, and can reduce injury to donor site.</p>

Repair of a soft tissue defect of medial malleolus with cross-leg bridge free transfer of anterolateral thigh muscle flap: a case report / 中华创伤杂志(英文版)

A 38-year-old man sustained a traffic accident injury to his right medial malleolus and leg. It was an open fracture of the right tibia and fibula accompanied by a large soft tissue defect of the right medial malleolus sized 12 cm multiply 4 cm. Doppler examination revealed that the tibialis posterior vessel was occluded due to thrombosis. The anterior tibial artery was patent. Three weeks after injury, the left anterolateral thigh muscle flap was harvested and transplanted to the right medial malleolus defect area for repair of the soft tissue defect, and an end-to-side anastomosis was performed between the posterior tibial vessel of the contralateral leg and the muscle flap's vascular pedicle. A split thickness free skin graft was used to cover the muscle flap and around the flap's vascular pedicle. The vascular pedicle was cut off after 28 days and the muscle flap survived completely. After 3-year follow-up postoperatively, the right tibia and fibula fractures were confirmed healing radiologically. The posterior tibial artery of contralateral leg was patent by clinical and Doppler examinations. This technique can be used to preserve the flow and patency of recipient arteries.

Repair of a large soft tissue defect in the leg with cross-leg bridge free transfer of a latissimus dorsi myocutaneous flap: a case report / 中华创伤杂志(英文版)

A 48-year-old man sustained a traffic accident injury to his left leg. It was an open fracture of the left tibia and fibula accompanied by a large soft tissue defect (27 cm multiply 7 cm). Doppler examination revealed the posterior tibial artery was occluded due to thrombosis. Three weeks after injury, the latissimus dors myocutaneous flap was elevated with a T-shaped vascular pedicle and was interposed between the two vascular ends of the posterior tibial vessel of the contralateral leg. Two end to end anastomoses were performed between the two vascular ends of the posterior tibial vessel of the contralateral leg and the latissimus dors myocutaneous flap's T-shaped vascular pedicle. The latissimus dorsi myocutaneous flap was used for repair of a large soft tissue defect of the left leg. The vascular pedicle was cut off after 28 days and the flap survived completely. After 3-years'follow-up postoperatively, a good contour was confirmed at the recipient area. The right tibia and fibula fractures were confirmed healing radiologically. The posterior tibial artery of contralateral leg was demonstrated patent by clinical and Doppler examinations.

Hand reconstruction using heterotopic replantation of amputated index and little fingers / 中华创伤杂志(英文版)

In cases of severe segmental injury across the hand and wrist, but one or other fingers are still in peak condition, the fingers can be selected for replantation at the forearm bones to restore pinch function. Here we reported an unusual case with a severe crush-avulsion amputated injury to the right hand caused by a machine accident. We conducted hand reconstruction using heterotopic replantation of the amputated index and little fingers. During 19 months follow-up, the bone union healed well with satisfactory outcome. The interphalangeal and metacarpophalangeal joint of the fingers after the heterotopic replantation had a good holding activity. This is a worthwhile procedure and the patient is satisfied with the result. The major disadvantage of this method is the poor appearance of the reconstructed fingers.

Staurospolin promotes the apoptosis of multidrug resistance tumor cell lines induced by adriamycin / 肿瘤研究与临床

Objective To investigate whether the protein kinase C inhibitor can promote the apopto- sis of multidrug resistance tumor cell lines which are induced by chemotherapy drugs.Methods Choose the KB/S(oral squamous cancer cell line)and KB/VCR(its multidrug resistant cell line)to compare the Adri- amycin-induced apoptosis with or without staurospolin(protein kinase C inhibitor).The apoptosis is stained with acridine orange,tested by flow cytometry,and approved by electron microscope.Results 36 hours after the treatment with 0.04 ?g/ml adriamycin,apoptotic cells of KB/S are 96.68%,and after 48 hours,the apop- totic cells of KB/VCR are 64.99%.When the concentration of adriamycin are augmented to 0.4?g/ml and 2.0?g/ml,the apoptotic cells of KB/VCR are 69.74% and 37.18% respectively.When treated with stau- rospolin together,the apoptotic cells of KB/VCR increased to 72.58%(?~2=4.5,P0.05)respectively.These results were testified by electron microscope and acridine orange-stain.Conclu- sion The resistance to apoptosis may be one of the mechanisms of multidrug resistance and the protein ki- nase C inhibitor may reverse this resistance by promoting the apoptosis of multidrug resistance tumor cells.
