BACKGROUND: There exists insufficient study with specific applicability regarding vascular distribution characteristics of sural nerve nutrient vessels of the distally based flap.OBJECTIVE: To investigate the distribution of sural nerve nutrient vessels of the distally based flap and provide an anatomical evidence for the design of operation on repair of foot injury.DESIGN: A single sample study.SETTING: Research Center of Clinical Anatomy, Fuzhou General Military Hospital of Nanjing Military Area Command of Chinese PLA, and Department of Orthopaedics, the 97 Hospital of Chinese PLA.PARTICIPANTS: Thirty-two samples of lower extremities whose blood vessels were perfused with red emulsion were provided by Research Center of Clinical Anatomy, Fuzhou General Military Hospital of Nanjing Military Area Command of Chinese PLA.METHODS: The origin of the blood vessels of distally based flap and deep communicating branches of the lesser saphenous vein in the samples were dissected and observed.MAIN OUTCOME MEASURES: ①The nutrient vessels of sural nerve of distally basde flap.②The nutrient vessels of lesser saphenous vein of distally based flap.③The superficial and deep communicating branches of lesser saphenous vein of distally based flap.RESULTS: There were 2 to 5 nutrient vessels in the distally based flap:one originating from the perforating branch of the lateral calcaneal artery was (0. 6 ± 0.2) mm in diameter and one from the terminal perforating branch of the peroneal artery was(0.8±0. 2) mm in diameter and they were (1.0 ± 1.3) and(2. 8 ± 1.0) cm, respectively, away from the lateral malleolus. The incidence of intermuscular septum perforating branches (0 to 3) was 96. 7%, 66.7% and 20. 0%, respectively, and their diameter was (0.9 ±0. 3), (1.0 ±0. 2) and (0. 8 ±0. 4) mm and their distance to lateral malleolus was(5.3 ±2. 1), (6. 8 ±2.8) and (7.0 ±4.0) cm, respectively. There were 2 types of nutrient vessels of the lesser saphenous vein of distally based flap, the nutrient vessels of nerve-vein and the ones of vein-nerve. The superficial and deep communicating branches of the lesser saphenous vein were(1.7 ±0. 5) mm in diameter and(3.4 ±0. 9) cm away from the lateral malleolus. They ended at the peroneal veins.CONCLUSION: The perforating branches of heel lateral artery, the terminal perforating branches and intermuscular septum perforating branches of the peroneal artery have sub-branches to deep fascia, skin, nerves and parenteral nutrient vessels. These sub-branches communicate and form vascular chain of lesser saphenous vein to sural nerve and vascular network of superficial and deep fascia. The superficial and deep communicating branches end at the peroneal veins.

Objective To investigate the expression and its clinical significance of adisintegrin and metalloprotease-17 (ADAM17) in human glioma.Methods The expressions of ADAM17 in human glioma were detected by immunohistochemical staining.The correlation between ADAM17 expression and the malignance of glioma was analyzed.Results Expression of ADAM17 in human gliomas increased.With the malignant degree,ADAM17 expression has also further increased.However,there was a less ADAM17 expression in normal human brain.The positive expression of ADAM17 in low malignant group was 75％ (18/24),of which 1 case were strong positive.The strong positive expression of ADAM17 was the majority (82.1％,23/28) in malignant group.Conclusion The expression of ADAM-17 was higher in human brain gliomas.With malignance degree increased,of the ADAM-17 expression has gradually increased,suggesting that ADAM-17 might play a certain role in the occurrence and development of glioma.

Objectives To explore therapeutic effect,indication and timing of nerve decompression for traumatic recurrent laryngeal nerve injury inducing vocal cord paralysis. Methods A total of 42 patients with recurrent laryngeal nerve injury inducing vocal cord paralysis within six months, were divided into nerve decompression group (15 cases), end to end anastomosis of recurrent laryngeal nerve group (six cases) and nonsurgical treatment (21 cases). Nerve decompression was performed in the patients who were operatively found to have compressing sutures or compression due to cicatricial hypertrophy. Results In 13 patients with a course less than four months, nerve decompression restored normal functional adductory and abductory motion of the vocal cord in 11 patients and motionless in two. Although functional motion of vocal cord was not seen in two patients with a course less than four months and two longer than four months, the mass and tension of the reinnervated vocal cord became much the same as the contralateral normal vocal cord, thus resuming symmetric vibration of the vocal cords and physiological phonation. End-to-end anastomosis of recurrent laryngeal nerve failed to restore motion of the glottis. Nevertheless, the procedures enabled adductory muscles to be reinnervated and then restored normal voice. Although nonsurgical treatment improved severe hoarseness, the vocal cord didn't restore normal functional motion of the vocal cord and normal voice. Conclusions Early and mid-stage recurrent laryngeal nerve decompression may restore normal motion of the vocal cord. End-to-end anastomosis of recurrent laryngeal nerve enables adductory muscles to be reinnervated and thus restores normal voice.
