BACKGROUND: Harmful stimuli induce increased production of calcitonin gene-related peptide(CGRP) in the spinal cord and dorsal root ganglion, causing also intense dilation of the microvessels. But it remains unknown whether vessel dilation and pain relief were accompanied by increased CGRP production when negative pressure is applied on the limbs for treatment of peripheral arterial occlusion diseases (PAOD).OBJECTIVE: To examine the changes of calcitonin gene-related peptide (GGRP) -immunoractive nerve fibers in the spinal cord and dorsal root ganglion in dogs with PAOD treated with negative pressure on the limbs.DESIGN: A randomized controlled retrospective study.SETTING: The department of general surgery of a military medical university.MATERIALS: This study was carried out at Xijing Hospital of the Fourth Military Medical University of Chinese PLA between January and August 2003. Seventeen adult male dogs weighing 12 - 18 kg, regardless of the gender, were selected.INTERVENTIONS: Seventeen dogs were randomly divided into three groups, namely the treatment group( n = 10), model group( n = 5), and the normal control group( n = 2). Posterior left leg ischemia was induced in dogs in the treatment and model groups, and those in the treatment group, but not the model group, were treated with negative limb pressure for 10 days 14days after model establishment. The spinal cord and dorsal ganglion at L1-5of these two groups were collected and stained immunohistochemically for observing the changes of GGRP-immunreactive nerve fibers. The dogs in the normal control group were also sampled in similar manner for immunohistochemical staining.MAIN OUTCOME MEASURES: Distribution of CGRP-immunoreactive nerve fibers in the spinal cord and dorsal ganglions of the three groups of dogs.RESULTS: In the dogs of the model group, GGRP-immunoreactive nerve fibers in the spinal cord and dorsal ganglions was significantly more numerous[ (75. 00 ±4. 30)%, (68.20 ± 2.60)% ] than those in the treatment and normal control groups[ (58. 20 ±5. 10)%, (52. 20 ±6.20)%; (37.00±4. 20)%, (34. 00 ± 1.40)%, P < 0.01]. The positive nerve fibers were less strongly stained in the treatment group than those in the model group,but still stronger stained those in the normal control group, with significant difference between the three groups( P < 0.01).CONCLUSION: Negative pressure on the limbs may attenuate the synthesis of CGRP-immunoreactive nerve fibers in the spinal cord and dorsal root ganglion and pain conduction following PAOD in dogs, so that harmful afferent stimuli are inhibited to relieve the pain in the limbs.

Objective To discuss the diagnosis and management of tracheomalacia complicating large goiter. Methods Clinical data of 36 patients with large goiter complicated by tracheomalacia at Xijing Hospital between 1992 and 2004 were retrospectively reviewed. Preoperative Valsalva-Mueller test were performed in all patients before undergoing subtotal thyroidectomy with tracheal suspension, and two patients were treated by subtotal thyroidectomy with tracheal suspension and tracheostomy. Results Valsalva-Mueller test was positive in all patients. The compressed tracheal cartilage disappeared in 2 cases, became thin and soft in other 34 cases. Thirty-four patients who underwent subtotal thyroidectomy with tracheal suspension recovered and 2 patients were resued by tracheal suspension with tracheostomy. There was no mortality. Postoperative 34 cases were followed-up from 6 months to 13 years. Thirty-two cases had no postoperative respiratory obstruction, 2 patients died of unrelated diseases. Conclusions The diagnosis of tracheomalacia from large goiter is based on Valsalva-Mueller test and operative detection. Subtotal thyroidectomy with tracheal suspension is the treatment of choice for tracheomalacia complicating large goiter.

AlM: To describe the expression of hypoxia-inducible factor-1α ( HlF-1α) and erythropoietin ( EPO ) in rats' corneal and evaluate its potential effect on corneal neovascularization ( CNV) growth.
METHODS:The young SD rats (3mo) was chosen and randomly divided into 2 groups, which were experimental group and normal control group. CNV model was established by alkali burn, and the length and area of CNV was observed everyday after operation by slit lamp. After that, the expression of HlF-1α and EPO was measured by SABC and RT-PCR methods at 1, 3, 5, 7, and 14d after alkali burn. The data was analyzed by SPSS 20. 0.
RESULTS:The area of CNV was increasing at 1, 3, 5, 7, and 14d after alkali burn, and the peak point appear at 7d. The growth speed was decreased after 14d. SABC method told us that no HlF-1αand very tiny amount EPO was detected at normal rats' corneal. The expression of the two factors increased at 1d after alkali burn in corneal epithelium and endoderm. The results of RT - PCR showed that a few amounts of HlF-1α and EPO mRNA were detected at normal group. The expression of the two factors was increased at 3d after alkali burn, and the peak value was found at 7d, however, it was decreased at 14d. Statistical difference was found at different time (P<0. 05).
CONCLUSlON: HlF- 1α and EPO is closely related to CNV.
