  • EXPERIMENTAL STUDY ON BRACHIAL PLEXUS INJURY INDUCED BY RADIATION IN RATS

    Objective To explore the changes of morphology and ventricornual motor neuronsin SD rats’ ventral horn of spinal cord after radiated as the therapy protocol for breast cancer, to discover the rule of radiationinduced injury of brachialplexus, and also if there exits the reversible conversion in neurons. Methods Twenty SD rats were selected. The left side of the rats was used as the radiation side, and the right side as the control side. The RIBPI animal models were established by divideddose of radiation. Using 2 Gy/time and 5 times/week, a total administered dose reached 30 Gy after 3 weeks. The behaviour of the rats was observed after radiation. At 3, 5, 7 and 9 weeks after the last radiation (n=4), the wet weights of biceps brachii muscle, upperlimb circumference and compound action potential were examined; the pathological changes of biceps brachiimuscle, the morphological changes, counts of the motor neurons in ventral horn and axons of bilateral spinal cord were observed by HE staining, argentums staining and toluidine blue staining. Results The rats showed lameness and a “claw hand” 3 weeks after radiation. Compared with control side, thewet weights of biceps brachii muscle and upperlimb circumference were significantly reduced, meanwhile, the compound action potential significantly decreased, and its latent period was also significantly prolonged 3, 5, 7 and 9 weeks (Plt;0.05). The histological observation: Musculocutaneous nerve showed decreased medullated fibers, heterogeneous ditribution and decreased density, thin myelin sheath, damaged nerve structure and collagen hyperplasia; biceps brachii muscle showed degeneration, fiber breakage and inflammatory cell infiltration; The account of motor neurons in ventral horn was significantly decreased in the radiation side with time extending, the sign of cell death, such as, the neurons crimple, and karyolysis were observed(Plt;0.05). Conclusion Large dose of X-ray can inducedbrachial plexus injury, and the lameness, a “claw hand”, biceps brachii muscle atrophy and the compound action potential abnormality.

  • REPAIR OF SOFT TISSUE DEFECTS OF WRIST AND FINGERS BY ANTEGRADE AND RETROGRADE DORSAL METACARPAL FLAPS WITH CUTANEOUS BRANCHES AS PEDICLES

    Objective To investigate the procedure and applications ofantegrade and retrograde dorsal metacarpal flaps with cutaneous branches as pedicles in repairing soft tissue defects of wrist and fingers. Methods From 1995 to 2003, we observed that the proximal and distal branches, deriving from the dorsal metacarpal artery, formed a consistent anastomosis arc subdermally. The anastomosis arc was paralleled to the dorsal metacarpal artery. Antegrade and retrograde dorsal metacarpal flaps could be designed using proximal anddistal branches as pedicles. Twenty-seven cases of soft tissue defects were treated by use of dorsal metacarpal flaps with cutaneous branches as pedicles, including 3 cases of defects on dorsum of hand with antegrade flaps, and 24 cases of defects on fingers with retrograde flaps ( index finger:12 cases; middle finger: 6 cases; ring finger: 4 cases; and little finger:2 cases). The dimensions of the antegrade flaps were 2.0 cm×4.0 cm~4.0 cm×6.0 cm, and the dimensions of theretrograde flaps were 2.5 cm×3.5 cm~3.0 cm×7.0 cm.The incision of the donor site was closed directly. Results All flaps survived. After a follow-up of 13 years, the texture and color of the flaps were good, and the shape and function of the donors were normal. Conclusion The antegrade or retrograde flap pedicled with the distal or proximal cutaneous branches of thedorsal metacarpal artery, is an optimal flap in repairing finger or wrist softtissue defects.

  • Risk factors of new-onset postoperative atrial fibrillation after off-pump coronary artery bypass grafting

    Objective To investigate the risk factors of new-onset postoperative atrial fibrillation (POAF) in patients who underwent isolated off-pump coronary artery bypass grafting (OPCAB). Methods Between January 2016 and January 2018, a total of 583 patients who underwent OPCAB in TEDA International Cardiovascular Hospital were retrospectively analyzed. There were 434 males and 149 females with an average age of 62.79±8.08 years. The patients were divided into 2 groups, a POAF group (n=158) and a non-POAF group (n=425) , in accordance with the occurrence of POAF. The perioperative clinical parameters of the two groups were analyzed by univariate analysis. Then, statistically significant factors in the univariate analysis were subjected to multivariate logistic regression analysis to determine if it was an independent risk factor for POAF. Results Univariate analysis showed that age≥65 years (P=0.012), history of chronic obstructive pulmonary disease (COPD, P=0.028), left atrial diameter (LAD)≥38 mm (P=0.016) and neutrophil-lymphocyte ratio (NLR, P=0.002) were related to POAF. Logistic multivariate regression analysis showed that age≥65 years (OR=1.717, P=0.006), LAD≥38 mm (OR=1.562, P=0.023) and higher NLR level (OR=1.215, P=0.022) were the independent risk factors of POAF after OPCAB, but not previous history of COPD (OR=2.489, P=0.326). Conclusion In patients with OPCAB, advanced age (≥65 years), LAD enlargement (≥38 mm) and higher NLR level are the independent risk factors of POAF after OPCAB.

  • A clinical study of myocardial viability in predicting the improvement of cardiac function after coronary artery bypass grafting in patients with ischemic heart failure

    ObjectiveTo explore the predictive value of myocardial vitality in the improvement of cardiac function after coronary artery bypass grafting (CABG) in patients with ischemic heart failure.MethodsFrom December 8, 2015 to November 12, 2018, 46 patients with ischemic heart failure who underwent CABG operation alone were collected retrospectively. There were 41 males and 5 females with an average age of 60.4±8.0 years. The myocardial vitality and number of different types of myocardium were measured. The clinical data of patients in the left ventricular ejection fraction (LVEF) improvement group (≥5%) and non-improvement group (<5%) were compared and analyzed. The correlation between each index and LVEF improvement was analyzed by logistic multivariate regression analysis, and the boundary value of hibernating myocardium between LVEF improvement and non-improvement was obtained by receiver operating characteristic (ROC) curve.ResultsThere were significant differences in the number of hibernating myocardium (15.0%±12.3% vs. 4.3%±4.5%, P=0.000), the number of normal myocardium (74.7%±13.7% vs. 82.4%±8.6%, P=0.027), and cardiac function classification (NYHA) development (−0.7±0.7 vs. −0.3±0.5, P=0.047) between the two groups, but there was no significant difference in other indexes between the two groups (P>0.05). Logistic regression analysis showed that the number of hibernating myocardium was an independent factor affecting the improvement of LVEF after CABG in patients with ischemic heart failure (OR=1.366, 95%CI 1.033-1.807, P=0.029). The ROC curve showed that the threshold value, sensitivity and specificity of hibernating myocardium were 15.0%, 43.8% and 100.0%, respectively.ConclusionThe percentage of hibernating myocardium to left ventricular wall area ≥15.0% can accurately predict the improvement of LVEF in patients with ischemic heart failure after CABG. Preoperative myocardial vitality assessment has important diagnostic value in predicting the improvement of cardiac function in patients with ischemic heart failure after simple CABG.

  • COMPARATIVE STUDY ON MICROPLATE AND ANCHOR FIXATION IN OPEN-DOOR CERVICAL EXPANSIVE LAMINOPLASTY

    Objective To evaluate the effectiveness of microplate fixation in open-door cervical expansive laminoplasty (ELP) by comparing with anchor fixation. Methods Between January 2005 and October 2008, 35 patients with multi-segment cervical spondylotic myelopathy were treated. Of them, 15 patients underwent ELP by microplate fixation (microplate group) and 20 patients underwent ELP by anchor fixation (anchor group). In microplate group, there were 10 malesand 5 females with the age of (51.2 ± 11.5) years; the disease duration ranged from 6 to 60 months (mean, 14 months); and the preoperative Japanese Orthopoaedic Association (JOA) score was 7.7 ± 2.5. In anchor group, there were 13 males and 7 females with the age of (50.7 ± 10.8) years; the disease duration ranged from 3 to 58 months (mean, 17 months); and the preoperative JOA score was 7.8 ± 2.9. There was no significant difference in the general data, such as gender, age, and JOA score between 2 groups (P gt; 0.05). Results All incisions healed by first intention. Thirty-five cases were followed up 24-68 months (mean, 32 months). The operation time was (113 ± 24) minutes in anchor group and (111 ± 27) minutes in microplate group, showing no significant difference (t=0.231 3, P=0.818 5). The rate of spinal canal expansion in microplate group (60% ± 24%) was significantly higher than that in anchor group (40% ± 18%) (t=2.820, P=0.008). The JOA scores of 2 groups at 3 months and 24 months after operation were significantly higher than the preoperative scores (P lt; 0.01). There was no significant difference in JOA score between 2 groups at 3 months after operation (t=1.620 5, P=0.114 6), but the JOA score of microplate group was significantly higher than that of anchor group at 24 months after operation (t=3.454 3, P=0.001 5). X-ray film, MRI, and CT scan at 3-6 months after operation displayed that door spindle reached bony fusion. There was no occurrence of ‘‘re-close of door’’ in 2 groups. The rate of compl ication in microplate group (13.3%, 2/15) was significantly lower than that in anchor group (25.0%, 5/20) (χ2=7.160 0, P=0.008 6). Conclusion ELP by microplate fixation can achieve the stabil ity quickly after operation, which can help patients to do functional exercises early, and has satisfactory effectiveness and less complications.

  • CLINICAL EFFECT OF METHYLPREDNISOLONE SODIUM SUCCINATE AND MOUSE NERVE GROWTH FACTOR FOR INJECTION IN TREATING ACUTE SPINAL CORD INJURY AND CAUDA EQUINA INJURY

    Objective To investigate the effect of methylprednisolone sodium succinate (MP) and mouse nerve growth factor (mNGF) for injection in treating acute spinal cord injury (ASCI) and cauda equina injury. Methods Between December 2004 and December 2007, 43 patients with ASCI and cauda equina injury were treated, including 33 males and 10 females with an average age of 43 years (range, 32-66 years). Injured vertebral columns were C2 in 1 case, C4 in 5 cases, C5 in 7cases, C6 in 3 cases, T8 in 1 case, T10 in 1 case, T11 in 2 cases, T12 in 3 cases, L1 in 9 cases, L2 in 5 cases, L3 in 3 cases, L4 in 1 case, and L5 in 2 cases. All the patients had sensory disturbance and motor dysfunction at admission. The Frankel scale was used for assessment of nerve function, 5 cases were rated as Grade A, 12 as Grade B, 22 as Grade C, and 4 as Grade D before operation. In 43 patients, 23 cases were treated with MP and mNGF (group A), 20 cases with MP only (group B). There was no significant difference in general data between 2 groups (P gt; 0.05). All the patients were admitted, received drug treatment within 8 hours of injury, and were given spinal canal decompression, bone transplantation, and internal fixation within 48 hours. The neurological function score systems of American Spinal Injury Association (ASIA) were used for neurological scores before treament, at 1 week and 2 years after treatment. The scores of the activity of daily l iving (ADL) were evaluated and compared. Results All the patients achieved heal ing of incision by first intention. Forty-three cases were followed up 24-61 months with an average of 30 months. Bone graft fusion was achieved after 6-17 months, 11 months on average with stable fixation. No death and compl ications of osteonecrosis and central obesity occurred. There was no significant difference in neurological function scores and ADL scores between 2 groups before treatment (P gt; 0.05); however, the neurological function scores and ADL scores at 1 week and 2 years after treatment were higher than those before treatment (P lt; 0.01) in 2 groups. Group A had higher neurological function scores and ADL scores than group B (P lt; 0.01). At 1 week and 2 years after treatment, the improvement rates of neurological function of group A (47.8%, 11/23 and 91.3%, 21/23) were significantly higher (P lt; 0.01) than those of group B (30.0%, 6/20 and 70.0%, 14/20). Conclusion MP and mNGF play an important role in improving the neurological function in patients with ASCI and cauda equina injury.
