止痛健骨方对兔膝骨关节炎模型滑膜及软骨修复的影响

目的 观察止痛健骨方对兔膝骨关节炎模型滑膜及软骨修复的影响。方法 建立兔膝骨关节模型,将兔随机分为正常对照组,模型对照组,骨刺宁组,止痛健骨低、中、高组共6组,每组6只,止痛健骨低、中、高剂量组分别给予4.48、8.96、17.92 g/kg止痛健骨方灌胃,骨刺宁组给予0.504 g/kg骨刺宁胶囊灌胃,正常对照组、模型对照组给予蒸馏水灌胃,每次10 mL/kg,每日1次,连续给药4周,检测各组兔右膝关节屈曲活动度、关节滑膜厚度及软骨未钙化厚度/钙化厚度,以及膝关节滑膜液炎性细胞,并进行比较。结果 实验4周后,模型对照组较正常对照组膝关节屈曲活动度、软骨未钙化厚度/钙化厚度明显减少,关节滑膜厚度、滑膜液炎性细胞明显增加（P<0.05）。与模型对照组比较,止痛健骨低、中、高剂量组膝关节屈曲活动度、软骨未钙化厚度/钙化厚度均明显增加,关节滑膜厚度、滑膜液炎性细胞减少,差异有统计学意义（P<0.05）。结论 止痛健骨方能抑制滑膜增生,增加非钙化软骨厚度,延缓软骨退变,增加关节屈曲活动度,这可能是其治疗膝骨关节炎的作用机制。     

大黄水煎剂对乌鳢离体肠道运动的影响（摘要）（英文）

[目的]观察不同浓度的大黄水煎剂对乌鳢离体小肠运动性能的影响,并探讨其药理作用机制。[方法]采用离体器官法,利用RM6240B生物信号采集与处理系统,记录不同浓度的大黄水煎剂对离体肠道作用前后的张力值。离体小肠平滑肌收缩曲线的描记;离体肠段下端固定在通氧气＂L＂形倒钩上,上端连接离体肌肉张力换能器,使肠段在恒温28℃今村液的麦氏浴槽内正常收缩。打开RM6240生物信号采集处理系统,以1 g砝码定标,待肠段收缩稳定后,先记录一段肠管在今村生理溶液恒温28℃时的收缩曲线5 min。在预试验的基础上依次将浓度为0.062、0.125、0.250、0.500 g/ml的大黄水煎剂分别取1 ml放入20 ml的今村液中混匀备用,然后分别记录各组加入不同稀释度大黄水煎剂后的收缩曲线5 min,观察肠管的收缩幅度（g）、收缩频率（次/min）,并从收缩曲线的基线改变,观察小肠平滑肌张力变化,以收缩基线上升表示张力增强,收缩基线下降表示肌张力减弱。[结果]药液浓度为0.062和0.125 g/ml的大黄水煎剂对乌鳢离体肠道收缩表现出明显的增强作用;药液浓度为0.250和0.500 g/ml的大黄水煎剂对乌鳢离体肠道收缩表现出抑制作用,在用药浓度0.500 g/ml前后差异极显著。可见,大黄水煎剂对乌鳢离体小肠平滑肌自发收缩幅度在低剂量有明显的增强效应,表现为正性变力作用,并呈剂量依赖性;在高剂量时有明显的抑制效应,并呈剂量依赖性,但对收缩频率影响不明显。建议在实际养殖过程中饲料中添加大黄的量为0.062 ～0.125 mg/L,用于鱼类细菌慈宁宫疾病治疗,提高鱼体免疫机能。[结论]大黄水煎剂对乌鳢离体肠道平滑肌的收缩活动有明显的效应。

Effects of Yangxue decoction and Yangxue-Jiedu decoction on imiquimod-induced psoriasis-like mouse model

AIM: To investigate and compare the effects of Yangxue (YX) decoction and Yangxue-Jiedu (YXJD) decoction on psoriasis-like mouse skin lesions. METHODS: BALB/c mice (n=50) were randomly divided into control group, model group, methotrexate (MTX) group, YX group and YXJD group (10 mice in each group). The psoriasis-like mouse model was induced by topical application of imiquimod cream on the back. The skin water/oil test pen was used to detect the water/oil content of the skin in the back of the mice. The pathological changes of the lesions were observed by HE staining and the thickness of the epidermis was measured. The immunohistochemical staining was used to observe the skin lesions, and the mRNA expression levels of interleukin (IL)-17, IL-23 and IL-1β in skin lesions were detected by real-time PCR. RESULTS: The skin lesions in YX, YXJD and MTX group were better than those in model group, with lower psoriasis area and severity index (PASI) score and skin thickness. The skin water/oil content in YXJD group was higher than that in model group (P<0.05). The expression of proliferating cell nuclear antigen (PCNA) and the positive expression of CD3⁺ T cells in the skin of YXJD group were lower than those in YX group, and the skin thickness was lower than that in YX group (P<0.05). The results of real-time PCR showed that relative mRNA expression of IL-17, IL-23 and IL-1β in YX group and YXJD group was lower than that in model group (P<0.05), and the relative mRNA expression of IL-1β in YXJD group was lower than that in YX group. Administration of YXJD decoction showed better therapeutic effect than MTX. CONCLUSION: YX decoction and YXJD decoction relieve imiquimod-induced skin lesions by reducing immune response. Meanwhile, the effect of YXJD decoction is better than that of YX decoction.     

Effects of Buzhong Yiqi decoction-medicated serum on drug resistance of human lung adenocarcinoma cell line A549/DDP to cisplatin

AIM:To investigate the effects of Buzhong Yiqi decoction-medicated serum on the drug resistance of human lung adenocarcinoma cell line A549/DDP to cisplatin. METHODS:Medicated serum containing Buzhong Yiqi decoction was prepared. The optimal dose of the medicated serum was selected by MTT assay. The A549 cells and A549/DDP cells were treated with the optimal medicated serum and cisplatin at different concentrations. The IC 50, resistance index and reversal index were determined. The cells were divided into control serum group, optimal medicated serum group, LY294002 group, LY294002 + optimal medicated serum group (combination group) and negative group. The expression of PI3K and Akt at mRNA and protein levels was detected by the methods of immunocytochemistry, Western blotting and real-time PCR. RESULTS:Treatment with 10% middle dose of medicated serum for 48 h was the optimal dose and time for medicated serum. The sensitivity of A549/DDP cells to cisplatin was obviously enhanced when the cells were exposed to the optimal medicated serum with the reversal index of 2.46. The expression of PI3K and Akt at mRNA and protein levels in optimal medicated serum group and combination group was significantly decreased. CONCLUSION:Buzhong Yiqi decoction decreases the resistance index by reducing the expression of PI3K in A549/DDP cells, thus increasing the sensitivity of A549/DDP cells to cisplatin.
