ABSTRACT
@#Objective To explore the effect of extracorporeal shock wave therapy (ESWT) combined with hyperbaric oxygen on nonunion after surgery. Methods 83 patients with nonunion were treated with ESWT combined with hyperbaric oxygen (treatment group), and 32 cases served as control group. ESWT application was conducted using a protocol totaling 3000 shocks per treatment. The treatment group received 3~5 times of treatment, at the same time hyperbaric oxygen therapy was performed. The control group received no treatment and was followed up at least 3 months after treatment. Results The overall success rate was 78.31% in the treatment group, while only 12.50% recovered in the control group (P<0.01). The complications of treatment group were less and negligible. Conclusion Treatment of nonunion by extracorporeal shock wave combined with hyperbaric oxygen is safe and effective.
ABSTRACT
@#Objective To discuss the treatment of acromioclavicular joint dislocation associated with clavicular distal end fracture and remedial means.Methods 28 cases of acromioclavicular joint dislocation associated with clavicular distal end fracture were treated with clavicular hook plate.28 patients included 4 cases of Allman's type Ⅰ,14 cases of type Ⅱ,10 cases of type Ⅲ.Classification of fracture included 9 traverse cases,14 oblique cases,3 comminuted cases,and 2 avulsion cases.There were 24 acute injury cases,4 obsolete injury cases.3 cases were open fractures.1 case was not successful by conservative management.After operation,early rehabilitation was emphasized and following-up was performed.The therapeutic effect was assessed with Karlsson standard.Results 28 patients were followed up for an average of 14.6 months(6～26 months).According to Karlsson standard:17 cases got A level,8 cases got B level,3 cases got C level.The rate of excellence was 89.3%.Conclusion Acromioclavicular joint dislocation associated with clavicular distal end fracture is not steady fracture and complicated with many ligaments avulsion often.Effective internal fixation on time and ligament repaired is necessary.
ABSTRACT
@#Objective To observe the effect of tilting table exercise and shengmaiyin on alpha 1 adrenogenic receptor (α1AR) in the superior mesenteric artery after spinal cord injury (SCI) in rabbits.Methods 46 rabbits were randomly divided into the sham group (n=6), SCI group (n=10), shenmaiyin group (n=10), exercise group (n=10) and combined treatment (shenmaiyin plus exercise) group (n=10). The rabbit model of SCI was established by complete transection of spinal cord at the T5 spinal segment. Tilting table exercise and shengmaiyin were applied to different groups for 28 days from 4 days after operation. The expression of α1aAR,α1bAR,α1dAR mRNA in the superior mesenteric artery was detected by RT-PCR at 31d after SCI.Results The mRNA expressions of α1aAR, α1bAR, α1dAR subtypes increased to different extent in rabbits of the shengmaiyin group, exercise group and combined treatment group compared with those of SCI group.Conclusion The role of tilting table exercise and shengmaiyin improving orthostatic hypotension after SCI in rabbits may be related to up-regulation of α1aAR, α1bAR, α1dAR mRNA in the superior mesenteric artery.
ABSTRACT
@#ObjectiveTo investigate the applying value of nerve root retractor in lumbar intervertebral disc operation.Methods116 consecutive patients underwent lumbar discectomy performed with a new approach using a series of semi-tubular retractor with consecutively increasing diameters, and their clinical data was analyzed retrospectively.ResultsThe mean operative time was 30～90 min per level, average 50 minutes and estimated blood loss was 50～200 ml per level, average 120 ml, no complications occurred. All patients were followed up 3 to 18 months after operation. All patients had substantial relief of their lumbago and radiculopathy, in which 96 without any symptoms, 3 cases with gently lumbago and limb numbness, 8 cases with gently lumbago, and 9 cases with lightly limb numbness.ConclusionThe nerve root retractor for lumbar discectomy made specially by ourselves can facilitate a good exposure to lumbar disc and intervertebral space, prevent injury of nerve roots or cauda equina and decrease volume of bleeding during operation, so as to make the procedure safe and effective.
ABSTRACT
@#ObjectiveTo observe changes of calcitonin gene related peptide (CGRP) and aetylcholinesterase (AChE) in motor endplate (MEP) after complete spinal cord injury (SCI) in the rat.MethodsSCI model of Wistar rats were established by transecting T10 spinal cord completely. The venters of the tibial anterior muscle were taken at 1, 2, 4 and 8 weeks postoperatively to carry out the experiment.The changes of CGRP and AChE in the MEP were investigated with immunohistochemical test.ResultsAfter complete SCI, the quantity and distribution of CGRP decreased in MEP of 1-week sample, and the changes of AChE were observed until 4-week sample, and although the staining was light and sparse, CGRP and AChE existed in MEP during 2 months postoperatively.ConclusionThere is degeneration of MEP in skeletal muscle after upper motor neuron injury; CGRP and AChE are related to the degeneration of MEP; CGRP test can show the changes of MEP earlier.
ABSTRACT
Objective:To investigate the quality of Herba Leonuri Preparations sold in market. Methods: The alkaloid content in preparations was determined according to the determination method in China Pharmacopoeia (1995). Results: There were significant differences among Herba Leonuri Preparations from different pharmaceutical factories, place of origin and batches. Conclusions: It is suggested that the determination item of stachydrine hydrochloride be added.
