目的 探讨冬凌草甲素（Ori）对白血病Molt-4细胞致凋亡作用及其可能的机制。 方法 将不同浓度的Ori（2.5、5、10、20、40 μmol/L）作用于Molt-4细胞。采用甲基噻唑基四唑（MTT）法检测细胞增殖，流式细胞术检测细胞凋亡，电子显微镜观察细胞凋亡超微结构的变化，Western blot方法分析凋亡相关蛋白及Caspase-3表达的变化。 结果 Ori可抑制Molt-4细胞的生长及诱导凋亡，并有时间-剂量依赖性；Ori可时间依赖性的下调抗凋亡蛋白Bcl-2的表达，上调促凋亡蛋白Bax和Bim表达以及活化Caspase-3。 结论 Ori可诱导Molt-4细胞凋亡，其机制可能与调节Bcl-2家族蛋白及活化Caspase-3有关。
Objective To evaluate and select essential medicine for bone fracture using evidence-based methods based on the burden of disease. Methods By means of the approaches, criteria, and workflow set up in the second article of this series, we referred to the recommendations of evidence-based or authority guidelines from inside and outside China, collected relevant evidence from domestic clinical studies, and recommended essential medicine based on evidence-based evaluation. Data were analyzed by Review Manager (RevMan) 5.1 and GRADE profiler 3.6 to evaluate quality of evidence. Results (1) 17 guidelines were included, six of which were evidence-based or based on expert consensus. We found that for fracture, global guidelines recommended surgical treatment and analgesics, while domestic guidelines recommended Chinese patent drugs. (2) A result of one RCT (low quality) indicated that Shang Ke Jie Gu Pian (name of a Chinese patent drug) shortened the clinical recovery time of fracture (MD=–4.2, 95%CI –5.25 to –3.14). A result of one RCT indicated that Shang Ke Jiu Ji Pian had a higher total clinical efficiency compared with San Qi Pian (name of a Chinese patent drug) (RR=1.28, 95%CI 1.11 to 1.47). A result of one RCT (low quality) indicated that Shang Ke Jiu Ji Pian (name of a Chinese patent drug) had a better effect than Shenyang Hong Yao Pian (name of a Chinese patent drug) in promoting the growth of osteotylus (RR=1.48, 95%CI 1.27 to 1.73) and also it had a higher clinical recovery rate (RR=1.62, 95%CI 1.37 to 1.9) compared to Shenyang Hong Yao Pian. A result of one RCT (moderate quality) indicated that Shang Ke Jiu Ji Pian was slightly better than Die Da Wan (name of Chinese patent drug) in regard to the recovery score of fracture (MD=0.25, 95%CI 0.026 to 0.47). A result of one RCT (low quality) indicated that compared to fracture reduction alone Shang Ke Jiu Ji Pian efficiently relieved pain (MD=–25.9, 95% –32.6 to –19.19) and shortened pain time (MD=–38.6, 95% –41.44 to –35.77). A result of one quasi-RCT (low quality) indicated that Shang Ke Jiu Ji Pian had a higher efficiency in relieving pain than benorylate (RR=1.13, 95%CI 1.04 to 1.23). A result of one RCT (low quality) indicated that Shang Ke Jiu Ji Pian had a higher efficiency than Shenyang Hong Yao Pian in relieving pain and swelling (RR=2.4, 95%CI 1.88 to 3.02). A result of one RCT (moderate quality) indicated that Shang Ke Jiu Ji Pian was superior to Die Da Wan in relieving pain and swelling (MD=–0.4, 95%CI –0.60 to –0.2). A result of two RCT (n=198) indicated that Shang Ke Jie Gu Pian caused no adverse reaction. With good applicability, Shang Ke Jie Gu Pian (taken with warm water or rice wine) cost 7.47 yuan daily. Conclusion (1) We offer a b recommendation for Shang Ke Jie Gu Pian and Jie Gu Qi Li Pian used in the treatment of adult fracture. (2) We should carry out more large-sample and controlled trials and improve outcome indicator in order to produce high-quality local evidence.
