Sixty Sprague-Dawley female rats were randomly divided into sham-operated groups and five ovariectomy (OVX) subgroups. Rats subjected to sham and OVX were treated with the vehicle, alendronate, and Zuogui Wan (ZGW) at the doses of low, medium and high lyophilized powder daily for 3 months, respectively. The gene or protein expression of NK1R, PPAR γ, and OSX were assayed by either quantitative polymerase chain reaction or Western blot analysis. The results showed that compared with the OVX group, ZGW could reduce the level of PPARγ and increase the levels of OSX and. Meanwhile, ZGW could prevent bone loss. In addition, we found ZGW upregulated for the NK1R mRNA or protein expression by promoting the expression level of transcription factor FoxO3 and increasing its binding to the NK1R promoter region -700/-200 sequence. These results suggest that the regulation of FoxO3 and NK1R played a role and contributed to the mechanism of ZGW underlying the increase in bone mass in the OVX rat model.

Polyphenolic acids are the widely occurring natural products in almost each herbal plant, among which rosmarinic acid (RA, C18H16O8) is well-known, and is present in over 160 species belonging to many families, especially the Lamiaceae. Aside from this herbal ingredient, dozens of its natural derivatives have also been isolated and characterized from many natural plants. In recent years, with the increasing focus on the natural products as alternative treatments, a large number of pharmacological studies have been carried out to demonstrate the various biological activities of RA such as anti-inflammation, anti-oxidation, anti-diabetes, anti-virus, anti-tumor, neuroprotection, hepatoprotection, etc. In addition, investigations concerning its biosynthesis, extraction, analysis, clinical applications, and pharmacokinetics have also been performed. Although many achievements have been made in various research aspects, there still exist some problems or issues to be answered, especially its toxicity and bioavailability. Thus, we hope that in the case of natural products, the present review can not only provide a comprehensive understanding on RA covering its miscellaneous research fields, but also highlight some of the present issues and future perspectives worth investigating later, in order to help us utilize this polyphenolic acid more efficiently, widely, and safely.

目的 探讨CCK-8与MTT法在检测左归丸含药血清干预大鼠骨髓间充质干细胞(bone marrow mesenchymal stem cells,BMSCs)增殖时所需的最佳实验条件,并比较两种方法的优缺点.方法 用左归丸含药血清进行干预P3 BMSCs,孵育结束后,分别加入CCK-8与MTT试剂,检测两种方法的最佳波长、培养时间、灵敏度和增殖时间.结果 CCK-8法与MTT法检测BMSCs的最佳波长分别为450 nm和550 nm,孵育时间分别为3 h和4 h,细胞接种密度分别为0.1×104/孔和0.25×104/孔.CCK-8法与MTT法在BMSCs接种密度分别高于0.25×104/孔和0.5×104/孔时,两种方法检测所得OD值均提早进入平台期,易出现假S型增长曲线.而当密度分别低于0.05×104/孔和0.1×104/孔时,细胞增加缓慢,难以形成S型增长曲线,不能反映出BMSCs的增殖特性.与CCK-8法相比较,在细胞密度低于0.1×104/孔或高于2×104/孔时,MTT法对BMSCs在翻倍时OD值增加的响应量无明显变化,差异无统计学意义.而细胞密度为0.25×104/孔至1×104/孔时,MTT法对BMSCs在翻倍时OD值增加的响应量明显增加,差异有统计学意义(P<0.05).结论 MTT法更适用于左归丸含药血清干预BMSCs增殖和分化的研究.
OBJECTIVE:To investigate the protective effects of Zuogui Wan (ZGW) on bone loss induced by ovariectomy (OVX) and its mechanism via orexin-A and orexin receptors in the osteoporosis rat model.METHODS:Fifty Sprague-Dawley female rats were randomly divided into sham-operated (sham) group and four OVX subgroups. Rats subjected to sham and OVX were treated with the vehicle (OVX, 1 mL/100 g weight, n = 10), 17β-estradiol (E2, 50 μg*kg-1*d-1), and ZGW at the doses of 2.3 (ZGW-L) and 4.6 (ZGW-H) g/kg/day lyophilized powder daily for 3 months, respectively. The serum biochemical parameters of 17β-estrogen (17β-E2), tartrate-resistant acid phosphatase (TRACP-5b) and bone alkaline phosphatase (BALP) were measured by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was used to detect the changes in the morphological structure in bones. Microcomputed tomography was used to evaluate the bone mineral density and microarchitecture of the distal femur. The gene or protein expression of orexin-A, orexin receptor 1 (OX1R), orexin receptor 2 (OX2R), osteoprotegerin (OPG) and receptor activator of nuclear factor-κB ligand (RANKL) were assayed by either quantitative polymerase chain reaction or Western blot analysis.RESULTS:Compared with the OVX group, ZGW could reduce the serum level of TRACP-5b and increased the serum levels of BALP and17β-E2 (P < 0.01). Meanwhile, ZGW could prevent bone loss and improved bone trabecular microarchitecture by increasing the trabeculae structure thickness and trabecular number, and arranging the trabeculae structure properly. Compared with the OVX group, it was upregulated for the orexin-A and OX2R mRNA or protein expression from the hypothalamus and tibiae, and OPG in the tibiae of ZGW groups (P < 0.01, < 0.05), while downregulated for the OX1R mRNA and protein expression in the tibiae and hypothalamus and RANKL from the tibiae (P < 0.01).CONCLUSION:ZGW exhibited a protective effect for PMOP that may be mediated via orexin-A and orexin receptors regulation.

OBJECTIVE To compare the therapeutic effect of thunder-fire moxibustion combined with vibration training and simple vibration training on low back pain of primary osteoporosis by Young's modulus of ultrasonic wave, and seek an objective evaluating method. METHODS A total of 60 patients were randomized into an observation group and a control group, 30 cases in each one. The patients in the two groups were treated with vibration training using whole body vibration treatment bed. In the observation group, thunder-fire moxibustion was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Ganshu (BL 18), Shenshu (BL 23) and Dachangshu (BL 25). The treatment was given once every other day, 3 times a week for 4 weeks. The visual analogue score (VAS), real-time shear wave elastography (RTSWE) and medical outcomes study 36-item short-form hearth survey (SF-36) were used to evaluate pain intensity, multifidus muscle tone (Young's modulus) and quality of life before treatment, after 4-week treatment and 1 month after treatment. RESULTS Compared before treatment, the VAS scores, Young's modulus of multifidus muscle and 5 dimensions of SF-36 (physical condition, body pain, general health, social function and mental health) after 4-week treatment and 1 month after treatment were significantly improved in the two groups (all P<0.05), the physiological role in the observation group after 4-week treatment and 1 month after treatment were improved (both P<0.05). In the observation group, the VAS scores, Young's modulus of multifidus muscle and 3 dimensions of SF-36 (physiological role, body pain and general health) after 4-week treatment and 1 month after treatment were superior to the control group (all P<0.05). CONCLUSION The therapeutic effect of thunder-fire moxibustion combined with vibration training is superior to simple vibration training in relieving low back pain intensity and multifidus muscle tone, and improving quality of life for primary osteoporosis. RTSWE technique can be an objective examination method to evaluate pain.

Background: Osteoarthritis is the main cause of disability and pain. Due to limited understanding of the disease mechanism, it is generally difficult to diagnose early and eliminate sequelae. The aim of this study was to identify novel biomarkers for osteoarthritis (OA) using a bioinformatics approach. Method: The gene expression dataset GSE82107 were obtained from the Gene Expression Omnibus (GEO) database. Matrix quality assessment was performed using corrplot packages and principal component analysis. The differentially expressed genes (DEGs) picked out using GEO2R tool. Enrichment analyses were performed using The Database for Annotation, Visualization and Integrated Discovery and Gene Set Enrichment Analysis (GSEA). Weighted correlation network analysis (WGCNA) was used to find gene modules highly associated with OA. Cytoscape with Molecular Complex Detection (MCODE) plug-in was utilized to analyze protein-protein interaction of these DEGs. Receiver operator characteristic curve analysis was used to evaluate the diagnostic effectiveness of genes. Results: Samples with different conditions (HC and OA) are obviously distinguished, and the distance between biological replicates is relatively close. In total, 1676 DEGs were identified. Enrichment analysis showed that there were some gene sets related to OA pathology, such as chondrocyte development. The results of WGCNA analysis showed that 298 genes were most positive associated with OA. 10 common genes obtained were selected as candidate core genes. ROC results showed that 5 of these genes had the greatest diagnostic value. Conclusion: This is the first study to identify biomarkers related to OA by combining multiple algorithms such as GSEA, WGCNA, MCODE and ROC. We suggest that GLG1, PAPSS2, CTSK, TIMP1 and SDC1 could serve as valuable biomarkers. Further studies are needed to examine the precise role and mechanism of these genes in OA.
《辅行诀脏腑用药法要》是一部重要的敦煌遗书.该书作者陶弘景以体用辨证观将五脏系统划分为脏之体与脏之用.调节脏气的本质就是调平脏之体与脏之用之间的失衡态.《辅行诀脏腑用药法要》的病证条文均引自《黄帝内经》的不同篇章,但以《灵枢·本神》《灵枢·邪在》《素问·脏气法时论》等为主.陶弘景以“体虚为实,用虚为虚”为脏腑虚实辨证的准则,对五脏病证加以概述.文章旨在辨析陶弘景五脏体用的内涵.
目的:探讨左归丸治疗绝经后骨质疏松症的分子机制之一是通过对β2-肾上腺素能受体(β2AR)介导的核转录因子-κB受体激活因子配体(RANKL)/骨保护素(OPG)信号通路的调节.方法:通过去卵巢法建立骨质疏松模型,将40只雌性SPF级SD大鼠随机分为模型组、假手术组、雌二醇(50 μg·kg-1·d-1)组、左归丸低、高剂量(2.3,4.6 g·kg-1)组.采用酶联免疫吸附实验检测血清骨转换标志物;显微CT对右侧股骨远端骨密度水平和骨小梁微结构进行测量和分析;实时荧光定量聚合酶链式反应(Real-time PCR)和蛋白免疫印迹法(Western blot)检测胫骨和下丘脑组织中β2AR,OPG,RANK mRNA和蛋白表达水平.结果:与模型组比较,左归丸可显著降低大鼠血清中Ⅰ型胶原交联羧基端肽(β-CTX)水平(P<0.01),增加骨特异性碱性磷酸酶(BALP)水平(P<0.01),减少卵巢摘除诱导引起的大鼠骨量丢失,改善股骨远端骨小梁显微结构水平.同时,左归丸高、低剂量组均能显著上调胫骨组织中OPG mRNA和蛋白表达(P<0.01),下调下丘脑组织β2AR mRNA和蛋白表达水平(P<0.01),同时也能显著下调胫骨组织中RANKL mRNA和蛋白表达水平(P<0.01).结论:左归丸改善围绝经期综合症,增加骨量和改善骨小梁显微结构水平的分子机制可能与对β2 AR介导的RANKL/OPG信号通路的调节有关.
