虫类药治疗乳腺癌骨转移思路探析

虫类药因其药性的猛烈,药物功效对症,成为治疗乳腺癌骨转移的常用药。相较于其他中药,虫类药对各类恶性肿瘤有较好的疗效,但在运用的同时还需注意,虫类药的毒性以及其对脏腑,尤其是肝脏的损伤,需动态关注患者各项生命体征变化,药用时间不宜过长,应严格遵守药物禁忌、配伍等规则,并要求临床医师辨证准确,密切观察患者病情变化。同时,虫类药的更多药物作用机制、临床方案的优化等,需进一步研究探讨。     

How to implement guidelines and models of care

In subjects older than 50 years, the presence of clinical risk factors (CRFs) for fractures or a recent fracture is the cornerstone for case finding. In patients who are clinically at high short- and long-term risk of fractures (those with a recent clinical fracture or with multiple CRFs), further assessment with bone mineral density (BMD) measurement using dual-energy absorptiometry (DXA), imaging of the spine, fall risk evaluation and laboratory examination contributes to treatment decisions according to the height and modifiability of fracture risk. Treatment is available with anti-resorptive and anabolic drugs, and from the start of treatment a lifelong strategy is needed to decide about continuous, intermittent, and sequential therapy. Implementation of guidelines requires further initiatives for improving case finding, public awareness about osteoporosis and national policies on reimbursement of assessment and therapy.     

绝经后血清BMP-7、OCN水平与骨质疏松的相关性研究

目的探究骨形态发生蛋白-7(BMP-7)、骨钙素(OCN)在绝经后骨质疏松(OP)患者血清中的水平与骨代谢指标骨特异性碱性磷酸酶(BAP)、I型胶原交联氨基末端肽(NTX)及骨密度(BMD)的相关性。方法选取2017年5月至2019年3月收治的93例绝经女性OP患者作为OP组;并以同期来我院进行健康体检的86例绝经女性作为对照组进行研究;以实时荧光定量PCR(qRT-PCR)法检测两组受试者血清BMP-7、OCN表达水平;以酶联免疫吸附法(ELISA)检测两组受试者血清BAP、NTX水平,计算BAP/NTX比值;利用双能X线骨密度仪测定两组受试者骨密度;分析OP患者血清BMP-7、OCN表达水平与骨代谢相关指标、BMD的相关性及BMP-7表达水平与OCN的关系; Logistic回归分析OP发生的影响因素。结果 OP组患者雌二醇水平、血清BMP-7、OCN、BAP/NTX、BMD水平均明显低于对照组(t=11.962、9.969、12.823、4.052、18.215,P均0.05); OP组患者血清BAP、NTX水平均明显高于对照组(t=4.014、9.092,P均0.05); OP患者血清BMP-7、OCN表达水平与BAP、NTX均呈负相关(P均0.05),与BAP/NTX、BMD均呈正相关(P均0.05),BMP-7表达水平与OCN呈正相关(P 0.05);雌二醇、BMD是影响OP发生的保护险因素(95%CI=0.536～0.978、0.335～0.916,P均0.05),BAP、NTX是影响OP发生的危险因素(95%CI=1.336～1.859、1.427～2.357,P均0.05)。结论绝经女性血清BMP-7、OCN表达水平下调,BMP-7、OCN与骨代谢指标及BMD密切相关,两者可能与BAP、NTX、BMD相互影响,从而在OP发展进程中发挥作用。

Risk factors of rib metastases in nasopharyngeal carcinoma patients with rib 99mTc- MDP foci on whole-body bone scansCSCD

Objective To investigate the correlation of rib 99mTc-MDP foci on whole-body bone scan with clinical variables and rib metastases in nasopharyngeal carcinoma(NPC) patients, and to screen the risk factors of rib metastases. Methods We retrospectively reviewed 312 NPC patients with rib 99mTc-MDP foci on wholebody bone scan. Chi-square test and logistic regression were performed to evaluate the correlation between clinical variables and rib metastases. Results In all 312 NPC patients, rib metastases were associated with T stage, skull base bone invasion, other bone metastasis, number of rib foci, lateral localization on rib and foci type (P<0.01), and the risk factors of rib metastasis included skull base bone invasion, other bone metastases, lateral localization on rib and foci type (P<0.05). In 176 patients with pure rib foci, rib metastases were closely related to T stage, skull base bone invasion, other bone metastasis, number of rib foci and lateral localization on rib (P<0.05), while only lobar distribution (P=0.029) was the effective risk factor. In 198 patients with single rib focus, rib metastases were affected by skull base bone invasion and foci type (P<0.01), while only foci type (P=0.000) was the effective risk factor. In all 566 rib foci, uptake level and localization on rib were the effective risk factors of rib metastases(P<0.01). Conclusion In NPC patients with rib foci on whole body bone scan, the effective risk factors of rib metastases include skull base bone invasion, other bone metastases, lateral localization on rib, foci type, uptake level and anterior and posterior localization on rib. Follow up should be the main way for the pure rib foci on unilateral ribs. For multiples rib foci on bilateral ribs or single rib focus combined with other bones foci, additional image modalities should be required to exclude bone metastasis. © 2020, CHINA RESEARCH ON PREVENTION AND TREATMENT.

Association between periodontitis and medication-related osteonecrosis of the jaw: A systematic review and meta-analysis

Consensus has yet to be reached about the prevention and treatment of medication-related osteonecrosis of the jaw (MRONJ), which is a treatment sequela of several antiresorptive therapies and other pharmaceutical interventions. Several epidemiologic studies have identified periodontal disease (PD) as a risk factor for this outcome. Thus, the objective of this systematic review and meta-analysis was to investigate this association and its magnitude. A systematic search in MEDLINE via PubMed, Scopus and ISI Web of Science, and a meta-analysis were undertaken. Observational studies that gathered information regarding prefixed definitions for both outcomes were selected, and the relevant information was then extracted, and their risk of bias was evaluated using the Newcastle-Ottawa Scale. The protocol of the study was registered on PROSPERO (CRD42019125646). The initial search yielded 757 eligible records, of which 12 were deemed adequate for inclusion (5 cohort studies and 7 case-control studies). On a random-effects meta-analysis, the risk of PD in MRONJ-affected sites compared with at-risk non-affected patients was significantly greater, with a risk ratio of 2.75 (95% CI: 1.67-4.52). Nonetheless, from a pooled analysis of three standardized periodontal measures (ie plaque index, clinical attachment loss and probing depth) no significant results were obtained. MRONJ appears to be associated with an increase in prevalence of PD. The direction of this association, and the factors influencing it must be investigated using further prospective data, and likewise, the possibility for using periodontal therapy as a prevention strategy must be looked into. Periodontal screening needs to be made an indispensable requisite for clinicians in order to establish a correct multidisciplinary approach in MRONJ.     

不同骨密度老年人群的体成分、肌力及心脏功能特点

目的 分析不同骨密度老年人群的体成分、肌力和心脏功能特点。方法 选择2019年1月至2021年12月在内蒙古自治区人民医院健康管理中心行骨密度检查年龄为65~80岁的500名受试者作为研究对象。采用人体成分分析仪检测并记录受试者骨骼肌指数、体脂肪率、脂肪控制、肌肉控制、右臂肌肉量、肌力；采用超声诊断仪检查并记录受试者心脏功能（EF、EDV、ESV、FS、HR、e/a）。结果 在500例研究对象中，骨量异常人数较多，占77 %，其中骨质疏松者93人（18.6 %），骨量减少者292人（58.4 %），骨量正常者115人（23%）。在男性中，骨质疏松者21人（8.4 %），骨量减少者153人（61.2 %），骨量正常者76人（30.4 %）；在女性中，骨质疏松者72人（28.8 %），骨量减少者139人（55.6 %），骨量正常者39人（15.6 %）；女性患骨质疏松的比例高于男性。女性的体脂肪率（37.20±4.13）高于男性（28.15±5.38）；女性骨骼肌指数（8.20±0.58）低于男性（9.23±0.55）（P＜0.05）。500例研究对象中需进行肌肉控制（增肌）的比例为55.6 % (278人),需进行脂肪控制（减脂）的比例为100 %（500人）。男性、女性分别按照骨密度分为骨质疏松组、骨量减少组及骨质正常组，三组体质量指数（body mass index, BMI)、T值、 Z值、骨骼肌指数、肌肉控制、右臂肌肉量、右手握力、左手握力比较，差异有统计学意义（P＜0.05）；年龄、体脂肪率、脂肪控制比较，差异无统计学意义（P＞0.05）。组间两两比较男性组BMI、T值、 Z值、骨骼肌指数、肌肉控制、右臂肌肉量、右手握力、左手握力组间比较差异有统计学意义（P＜0.05）；女性组T值、 Z值、骨骼肌指数、肌肉控制、右臂肌肉量、右手握力、左手握力组间比较差异有统计学意义（P＜0.05）。Pearson 相关分析显示，T值与骨骼肌指数、BMI、右臂肌肉量及右手握力呈正相关；相较BMI，T值与骨骼肌指数、右臂肌肉量相关性更高；与肌肉控制（增肌）呈负相关（r值= – 0.326，P=0.000）；与体脂肪率及脂肪控制无相关性。心脏功能EDV（F=0.042,P=0.958）、ESV（F=0.008,P=0.992）、EF值（F=0.060,P=0.942）、FS值（F=0. 057,P=0.945）、HR（F=0. 032,P=0.969）组间比较差异无统计学意义（P＞0.05）；e/a（F=3.768,P=0.034）比较差异有统计学意义（P＜0.05）。结论 老年人群骨量异常比率较高，随着骨密度减低，骨骼肌指数及肌力也会下降，且骨质疏松患者易出现心脏舒张功能减低。利用生物电阻抗测定人体成分可以分析骨质疏松患者人体成分变化，能够更细化地了解其肌肉和脂肪的含量，为进一步预防、治疗骨质疏松及优化老年人人体成分提供依据。
