为了促进对绝经后骨质疏松症(postmenopausal osteoporosis,PMOP)中药治疗疗效的提高及其作用机制的进一步研究,笔者检索了CNKI数据库中2012年至2021年间常用中药复方治疗PMOP的文献,并梳理总结了PMOP的辨证分型、常用的治疗方药及其机制,发现中药治疗PMOP可有效缓解疼痛、提高患者骨密度、改善雌二醇水平,提升患者生活质量。在机制方面,可通过调节OPG/RANKL、Wnt/β-catenin、JAK/STAT信号通路,或通过提高OX、ERmRNA和蛋白表达等,达到促进成骨细胞分化,减少破骨细胞生成,提高骨密度、平衡骨代谢等作用。中药治疗PMOP机制研究已深入到分子甚至基因水平,建议今后可从骨代谢、骨免疫、骨微结构、肠道菌群、氧化应激与炎症反应、铁过载等方面进一步研究,丰富中药治疗PMOP的机制,阐明中药的作用靶点,增强科学性。 相似文献

本文对中医研究骨质疏松症的近况进行了综合性评述。认为:中医近年来通过借助一些现代医学手段,无论在发病机理、辨证分型及治疗等方面,皆取得了可喜的成绩。在理论方面,通过多位学者的研究,进一步证明了中医理论中肾主骨及骨的强健、脆弱与肾的关系有一定的科学性。在辨证分型方面,除了肾虚型,尚有气滞血瘀、肝郁、脾虎等证型,使分型趋于更加全面、合理。在治疗方面,通过大量的临床及动物试验,以及与治疗此病的西药进行对比,提示中药治疗骨质疏松症的内在物质基础,可能与调节机体内分泌、免疫、微量元素等系统有关,并可看出中药治疗此病具有明显的临床效果,且副作用少,宜于长期服用。 相似文献

近年来中药对骨代谢影响的研究日益增多,从动物实验到临床研究,从作用机理到临床疗效观察,从单组分、单味中药到中药复方制剂,研究的广度和深度不断拓展,也越来越显示出中药在治疗骨代谢疾病特别是骨质疏松症等方面显著而独特的疗效。由于西药在治疗骨质疏松症时所显示出的毒副作用,使得中药的开发和研究显得尤为重要。现将近年来中药对骨代谢影响的研究进展作一综述。 相似文献

半月板组织工程的研究进展 总被引:1,自引:1,他引:0
半月板损伤临床常见,据美国矫形外科学会2008年的统计资料,美国每年全膝关节置换手术>250000例,其中半月板损伤是骨性关节炎进展的关键因素。然而,半月板仅外周1/3有血液供应,发生于此部位的损伤采用缝合治疗可以愈合;而内侧缘2/3均为无血管区,损伤后自行愈合能力较差,目前临床上针对这类损伤多采用半月板部分切除或全部切除术。 相似文献

Improved sexual behavior in male rats treated with a Chinese herbal extract: hormonal and neuronal implications 总被引:3,自引:0,他引:3

Aim: To investigate the influence of an extract obtained from five Chinese medicinal plants on sexual behavior of adult male rats. Methods: The extract was administered at doses of 30, 60 and 120 mg/kg by oral gavage, acutely (one time, 45 min before mating test) or subchronically (daily for 10 days) in sexually potent and sexually sluggish/impotent rats. Sexual behavior, serum levels of luteinizing hormone (LH) and testosterone (T) were evaluated in treated rats and compared with controls receiving vehicle. The effect of the extract on central dopaminergic neurotransmission was assessed in the nucleus accumbens using a microdialysis technique. Results: In sexually potent rats, both acute and subchronic treatment with the extract dosed at 30 and 60 mg/kg reduced mount latency and intromission latency. In sluggish/impotent rats, the acutely administered extract at the dose of 60 mg/kg shortened ejaculation latency, whereas subchronically administered at the doses of 30 and 60 mg/kg, reduced mount, intromission and ejaculation latencies, increasing also the percentage of mounting and ejaculating rats. The extract dosed at 60 mg/kg significantly increased LH and T following acute and subchronic administration and increased 3,4-dihydroxyphenylacetic acid levels in the nucleus accumbens, 30 min after the acute administration. Conclusion: The improvement in both appetitive and consummatory components of sexual behavior observed in male rats treated with the extract could be ascribed to increased serum T level in parallel with the activation of the central dopaminergic system. 相似文献

脊柱侧凸矫形手术早期并发症的处理及预防 总被引:2,自引:2,他引:0
随着脊柱外科的迅速发展,国内越来越多的医院已经或正在开展各类脊柱侧凸的手术治疗。但由于脊柱作为人体的支柱,其解剖关系复杂,邻近有许多重要组织和器官,因此手术相关并发症并不少见,也不容忽视。如何预防和减少手术并发症,已经是迫在眉睫的任务,需要我们不断研究和深入探讨。根据发生时间可将手术并发症分为术中、术后早期及术后晚期并发症。现对脊柱侧凸矫形手术中及术后早期并发症的的处理及预防进行分析。 相似文献

Aim: To investigate the effects of 17β-estradiol (E2), Peganum harmala extract (PHE) and caloric restriction (CR) on various testis parameters during aging. Methods: Twelve-month-old male rats were treated for 6 months with either E2 or PHE, or submitted to CR (40%). Results: Our results show that estrogens and CR are able to protect the male gonad by preventing the decrease of testosterone and E2 levels as well as the decrease of aromatase and estrogen receptor gene expressions. Indeed, E2, PHE and CR treatments induced an increase in the superoxide dismutase activities and decreased the activity of testicular enzymes: gamma-glutamyl transferase, alkaline phosphatase, lactate deshydrogenase as well as the aspartate and lactate transaminases in aged animals. In addition, the testicular catalase and gluthatione peroxidase activities were enhanced in E2, PHE and CR-treated rats compared to untreated animals at 18 months of age. Moreover, the positive effects of estradiol, PHE and CR were further supported by a lower level of lipid peroxidation. Recovery of spermatogenesis was recorded in treated rats. Conclusion: Besides a low caloric diet which is beneficial for spermatogenesis, a protective antioxydant role of estrogens is suggested. Estrogens delay testicular cell damage, which leads to functional senescence and, therefore, estrogens are helpful in protecting the reproductive functions from the adverse effects exerted by reactive oxygen species (ROS) produced in large quanti- ties in the aged testis. 相似文献
