Therapeutic effects of Radix Dipsaci, Pyrola Herb, and Cynomorium Songaricum on bone metabolism of ovariectomized rats

ABSTRACT: BACKGROUND: It is not yet determined whether herbs can be used as alternative medicines for therapy of osteoporosis. The objective of this study was to evaluate the effects of herbal medicines, such as Radix Dipsaci (RDD), Pyrola Herb (PHD), and Cynomorium songaricum decoction (CSD), on osteoporotic rats induced by ovariectomy (OVX). METHODS: OVX or sham operations were performed on 69 virgin Wistar rats that were divided into six groups: sham (sham, n = 12), OVX control group (OVX, n = 12), and OVX rats with treatments (diethylstilbestrol, DES, n = 12; RDD, n = 11, PHD, n = 11, and CSD, n = 11). Non-surgical rats served as normal control (NC, n = 12). The treatments began four weeks after surgery and lasted for 12 weeks. Bone mass and bone turnover were analyzed by histomorphometry. Levels of protein expression and mRNA of OPG and RANKL in osteoblasts (OB) and bone marrow stromal cells (bMSC) were evaluated by immunohistochemistry and in situ hybridization. RESULTS: Compared to NC and sham rats, trabecular bone formation was significantly reduced in OVX rats, but restored in DES-treated rats. Treatment with either RDD or PHD enhanced trabecular bone formation remarkably. No significant change of bone formation was observed in CSD-treated rats. OPG expression of protein and mRNA was reduced significantly in OB and bMSC of OVX control rats. RANKL expression of protein and mRNA was increased significantly in OB and bMSC of OVX control rats. These effects were substantially reversed (increased in OPG and decreased in RANKL) by treatment with DES, RDD, or PHD in OB and bMSC of OVX rats. No significant changes in either OPG or RANKL expression were observed in OB and bMSC of OVX rats treated with CSD. CONCLUSIONS: Our study showed that RDD and PHD increased bone formation by stimulating overexpression of OPG and downregulation of RANKL in OB and bMSC. This suggests that RDD and PHD may be used as alternative therapeutic agents for postmenopausal osteoporosis.

褪黑素及其受体介导的耳甲电刺激降糖效应机制研究进展及展望＊

2型糖尿病发病率逐年攀升，给社会、家庭和个人都带来巨大负担。大量临床研究表明，耳针对高血糖状态具有明显的改善作用，且具有方便、简捷、利于操作等优势。由于2型糖尿病的发生与褪黑素的低水平密切相关，本文试图从褪黑素及其受体的角度进一步揭示耳甲电针降糖效应机制，为临床治疗糖尿病提供科学依据。     

耳甲电针治疗功能性消化不良的临床效果

目的:观察耳甲电针治疗功能性消化不良的疗效。方法:选取2018年6月至2019年5月北京同仁医院收治的功能性消化不良患者90例作为研究对象,按照随机数字表法分为对照组和观察组,每组45例,对照组采用对照刺激,观察组采用耳甲电针刺激,所有患者治疗前后均使用功能性消化不良主要症状评分表、功能性消化不良生命质量量表(FDDQL)、汉密尔顿焦虑量表(HAMA)、汉密尔顿抑郁量表(HAMD)、抑郁自评量表(SDS)评估患者症状的严重程度,并参照功能性消化不良中医诊疗专家共识意见和功能性消化不良中西医结合诊疗共识意见的疗效评估方法,对比分析观察组与对照组治疗功能性消化不良的疗效。结果:观察组和对照组治疗前主要症状评分表、功能性消化不良生命质量量表(FDDQL)、汉密尔顿焦虑量表(HAMA)、汉密尔顿抑郁量表(HAMD)、抑郁自评量表(SDS)差异无统计学意义(P>0.05),治疗后观察组症状及量表评分与对照组差异有统计学意义(P<0.05)。观察组治疗有效率82.22%,对照组治疗有效率57.78%,差异有统计学意义(P<0.05)。结论:耳甲电针对于功能性消化不良的各项症状具有较好的疗效。     

酪酸梭菌对轮状病毒性肠炎血清促炎因子的影响

观察酪酸梭菌对轮状病毒肠炎患儿血清中促炎因子IL-1、IL-6、IFN-γ水平的影响及与临床疗效之间的关系。将轮状病毒性肠炎患儿98例随机分为试验组和对照组,均予利巴韦林抗病毒、蒙脱石散止泻,有发热予对乙酰氨基酚,有脱水予补液对症等常规治疗,试验组加用酪酸梭菌0.5片,1天3次,温开水冲服。检测2组患儿治疗前和治疗72 h后血清IL-1、IL-6、IFN-γ,同时比较分析2组患儿临床疗效与促炎因子水平的关系。治疗72 h后2组患儿血清IL-1、IL-6、IFN-γ水平均有下降（P＜0.05）,试验组显著性低于对照组（P＜0.01）。酪酸梭菌对轮状病毒肠炎具有较好的疗效,能降低血清IL-1、IL-6、IFN-γ水平,从而抑制患儿的免疫性炎症反应,促进疾病痊愈。     

口服乳糖酶对婴幼儿轮状病毒肠炎80例的临床疗效影响

目的 分析乳糖酶对婴幼儿轮状病毒肠炎临床疗效的影响,为该病提供有效的辅助治疗方法。方法 选择莎车县人民医院儿科病房住院2017年1月25日至2018年4月1日明确诊断婴幼儿轮状病毒肠炎病人160例,依据随机数字表法随机分为对照组和观察组,每组80例。观察组在对照组常规治疗基础上再口服乳糖酶制剂,以腹泻、呕吐、发热及腹胀等症状消失的时间作为疗效判断指标,对各组病例的疗效情况进行分析。结果 口服乳糖酶时间＜3 d时,对照组和观察组的总有效率分别为32.50%和36.25%,差异无统计学意义(χ²=0.249,P=0.618);口服乳糖酶时间≥3 d时,对照组和观察组的总有效率分别为77.50%和95.00%,差异有统计学意义(χ²=10.329,P=0.001)。观察组口服乳糖酶＜3 d和≥3 d间比较,差异有统计学意义(χ²=61.20,P=0.000)。结论 口服乳糖酶对婴幼儿轮状病毒肠炎治疗具有明显辅助作用,但作用显现至少需要口服时间达到3 d,应该引起临床重视。
