膝关节镜术后结合活血祛瘀汤内服对膝关节炎患者骨代谢指标及炎性指标的影响

目的:研究膝关节镜术后结合活血祛瘀汤内服对膝关节炎患者骨代谢指标及炎性指标的影响。方法:选取2013年6月至2016年5月抚顺市中医院骨科住院部收治的进行关节镜清理术的膝骨关节炎患者68例进行回顾性分析,按照术后治疗方法的不同分为观察组和对照组,每组34例。观察组内服活血祛瘀汤(58膝),对照组行单纯关节镜清理术(62膝)。将2组患者术后6个月随访疗效结果进行比较。结果:6个月治疗结束后,观察组总有效率81. 02%,显著高于对照组的48. 55%,差异有统计学意义(P 0. 05),观察组治疗后夜间卧床休息时疼痛、晨僵或起床后疼痛加重、绞锁、肿胀以及跛行优于对照组,差异有统计学意义(P 0. 05)。观察组治疗后TNF-α、IL-6改善显著,与对照组比较,差异有统计学意义(P 0. 05),观察组与对照组治疗后COMP、CTX-Ⅱ、CTX-Ⅰ、MMP-3治疗后效果显著,且观察组优于对照组,差异有统计学意义(P 0. 05)。结论:活血祛瘀汤可明显降低膝关节术后患者炎性反应递质水平,患者COMP,CTX-Ⅱ,CTX-Ⅰ和MMP-3指标亦有显著改善,患者综合治疗疗效优于患者单纯使用关节镜下清理术疗效。

Introduction

Little is known about dementia incidence in diverse populations of oldest-old, the age group with highest dementia incidence.

Supraclavicular lymphadenopathy following COVID-19 vaccination: an increasing presentation to the two-week wait neck lump clinic?

The first COVID-19 vaccination was given in December 2020 and there is an effort to vaccinate the international population on a massive scale. Common side effects from the vaccine include headache and tiredness. Regional lymphadenopathy has been described in relation to other vaccines. We describe two cases of supraclavicular reactive lymphadenopathy presenting in patients who had the COVID vaccination in the ipsilateral arm. Awareness of this diagnosis is important for patients presenting to the neck lump clinic.

腹腔镜肝癌根治术的热点与未来发展

随着腹腔镜肝切除技术的发展与推广，腹腔镜肝切除中的一些难点，如术中出血的控制、解剖性肝切除、巨大肝癌切除、腹腔镜下联合肝脏分割与门静脉支结扎的二步肝切除术(ALPPS)等方面均基本解决。术中超声与荧光染色技术也得到普及。本文就上述问题做一概述，并对腹腔镜肝切除未来发展提出思路，以进一步推动我国腹腔镜肝切除的技术进步。     

Mimengosides J and K: two new neuroprotective triterpenoids from the fruits of Buddleja lindleyana

Two new 11-methoxyl substituted triterpenoids, named as mimengosides J (1) and K (2), along with seven known compounds, were isolated from the fruits of Buddleja lindleyana. Their structures were elucidated on the basis of spectroscopic analysis. In addition, the new ones were evaluated for protective effects against damage of SH-SY5Y cells induced by 1-methyl-4-phenylpyridinium ion (MPP⁺) and the results indicated that those may be one of the candidate compositions of Buddleja lindleyana for the treatment of neurodegenerative disease.
