认识骨关节炎与骨质疏松的关系推进骨关节炎分层治疗

认识骨关节炎和骨质疏松的关系及骨关节炎亚型，为实现患者的分层管理以及精准医疗奠定了基础。骨质 疏松是造成部分骨关节炎进展的重要原因，软骨下骨骨代谢异常和微结构改变是其中重要的病理基础。双膦酸盐 等抗骨质疏松药物可能是伴骨质疏松的骨关节炎亚型患者治疗的新选择。     

非体外循环主动脉弓缩窄外科手术体会

目的:回顾性分析非体外循环外科治疗主动脉弓缩窄手术特点,探讨治疗主动脉弓缩窄的最佳手术方式。方法:回顾性分析我院2009年6月至2018年6月,收治的经左后外侧开胸行主动脉弓缩窄矫治术的患儿80例,依据手术方式分为两组,I组:62例,平均年龄12.2(6.0,37.3)个月;体质量(11±5.4)kg;采用主动脉端端吻合术。Ⅱ组:18例,年龄18.7(8.5,35.7)个月;体质量10.8(7.4,14.2)kg;采用左锁骨下动脉翻转补片成形术。观察两组患儿年龄、体质量、以及诊断、主动脉狭窄段部位、狭窄段长度、狭窄段内径等分布,并记录术前、术后上下肢收缩压峰值压差、术后呼吸机辅助呼吸时间、ICU滞留时间、术后随访上下肢血压等一般情况。结果:I组主动脉狭窄段长度(9.93±4.8)mm,最狭窄处内径(2.84±0.49)mm,II组狭窄段长度15(10,20)mm,最狭窄处内径(3.33±0.59)mm,两组病变,差异有统计学意义(P<0.05);I组术后呼吸机辅助时间为9(6.6,16.4)h、ICU滞留时长37.2(20.6,70)h,II组分别是14.5(7.5,21.4)h、45.2(20,93.9)h,I组患儿带管时间更短(P<0.05); I组中并发乳糜胸1例,II组中并发左侧气胸1例,两组均未见出血、死亡等并发症;余各项指标两组之间均差异无统计学意义。结论:对于狭窄段较短的患者可行主动脉端端吻合,而狭窄段较长,且狭窄内径不过窄可以选择左锁骨下动脉翻转补片成形术。     

结肠息肉内镜下黏膜切除术与高频电切术的疗效比较

目的研究内镜下黏膜切除术(EMR)与高频电切术在结肠息肉患者中的治疗效果。方法选取2016年2月-2018年12月在我院接受择期手术治疗的90例结肠息肉患者作为对象,按照随机数字表法分为A组和B组,各45例。A组行EMR手术,B组行高频电切术。比较两组的治疗有效率、住院时间、手术时间、术中出血量、术后肠功能恢复时间、术后并发症发生率以及不良反应发生率。结果 A组的治疗有效率(95.56%)高于B组(80.00%)(P0.05)。A组住院时间为(4.61±1.13) d,短于B组的(6.52±1.21) d(P0.05); A组手术时间为(85.24±16.54) min,短于B组的(105.52±16.33) min(P0.05)。A组术中出血量为(33.46±8.51) ml,短于B组的(46.67±8.42) ml(P0.05)。A组术后肠功能恢复时间为(16.54±4.72) h,短于B组的(25.61±4.55) h(P0.05)。A组的并发症发生率(2.22%)、不良反应发生率(4.44%)均低于B组(P0.05)。结论采用内镜下黏膜切除术对结肠息肉患者进行治疗,疗效显著,安全性较高,值得应用与推广。     

经皮后路脊柱内镜下椎间盘髓核摘除术治疗神经根型颈椎病

目的探讨经皮后路脊柱内镜下椎间盘髓核摘除术(PPECD)治疗神经根型颈椎病(CSR)的效果。方法采用随机数字表法将2016-10-2018-10间新里程安钢总医院收治的180例CSR患者分为2组,每组90例。对照组行颈椎前路椎间盘切除(ACD)内固定术,观察组行PPECD。比较2组的治疗效果。结果观察组手术时间、术中出血量和住院时间少于对照组,差异有统计学意义(P<0.05)。2组手术前、后的病椎椎间高度差异均无统计学意义(P>0.05)。2组术后第6个月和12个月的颈椎曲度、VAS和JOA评分均较术前明显改善,且观察组的改善效果均优于对照组,差异有统计学意义(P<0.05)。观察组术后第12个月的颈椎功能明显优于对照组,差异有统计学意义(P<0.05)。结论 PPECD治疗CSR,创伤小、手术时间短、术后康复快,可有效缓解患者的症状和改善颈椎曲度及颈椎功能。

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.
