2Screening for main components associated with the idiosyncratic hepatotoxicity of a tonic herb, Polygonum multiflorum显示文摘典型药用的植物的主要成分,蓼 multiflorum (用汉语的 Heshouwu ) ,那导致特质的肝损害仍然保持不清楚。我们的以前的工作证明了有 lipopolysaccharide (LPS ) 的无毒的剂量和 Heshouwu 的治疗学的剂量的 cotreatment 能在老鼠导致肝损害,而独唱治疗不能导致看得见的损害。在现在的工作,用成分大美人和敲门在里面策略,我们发现 Heshouwu 的乙醇醋酸盐(EA ) 摘录在对待 LPS 的老鼠显示了可比较的特质的 hepatotoxicity 到整个摘录。结果显示血浆丙氨酸 aminotransferase, aspartate aminotransferase,和肝 histologic 的重要举起变化,而另外的分开的部分没能导致肝损害。有另外的分开的部分的 EA 摘录的混合在对待 LPS 的老鼠导致了可比较的特质的 hepatotoxicity 到整个摘录。化学分析进一步揭示了那 2,3,5,4-tetrahydroxy trans-stilbene-2-O -- 配糖物(trans-SG ) 和它的 cis 异构体是在 EA 的二主要混合物摘录。而且,孤立的 cis- ,并且不它的 trans 异构体,显示的可比较的特质的 hepatotoxicity 到在对待 LPS 的老鼠的 EA 摘录。cis-SG 的更高的内容从与收集的将军相比与 Heshouwu 联系的实际的肝沉醉病人在 Heshouwu 白酒或准备被检测样品。另外,血浆 metabolomics 分析证明 cis-SG-disturbing 充实显著地不同于的小径在对待 LPS 的老鼠的 trans-SG。所有这些结果建议 cis-SG 仔细与 Heshouwu 的特质的 hepatotoxicity 被联系。认为 trans-SG 的 cis-trans 异构化被紫外光或日光调停,我们的调查结果为在药发现控制 photoisomerization 并且为 Heshouwu 和芪相关的药的临床的使用用作参考。Chunyu Li Ming Niu Zhaofang Bai Congen Zhang Yanling Zhao Ruiyu Li Can Tu Huifang Li Jing Jing Yakun Meng Zhijie Ma Wuwen Feng Jinfa Tang Yun Zhu Jinjie Li Xiaoya Shang Zhengsheng Zou Xiaohe Xiao Jiabo Wang 2017Frontiers of Medicine2017,11,2:41
3New incompatible pair of TCM:Epimedii Folium combined with Psoraleae Fructus induces idiosyncratic hepatotoxicity under immunological stress conditions显示文摘Epimedii Folium(EF)combined with Psoraleae Fructus(PF)is a common modern preparation,but liver injury caused by Chinese patent medicine preparations containing EF and PF has been frequently reported in recent years.Zhuangguguanjiewan pills(ZGW),which contain EF and PF,could induce immune idiosyncratic liver injury according to clinical case reports and a nonhepatotoxic dose of lipopolysaccharide(LPS)model.This present study evaluated the liver injury induced by EF or PF alone or in combination and investigated the related mechanism by using the LPS model.Liver function indexes and pathological results showed that either EF or PF alone or in combination led to liver injury in normal rats;however,EF or PF alone could lead to liver injury in LPS-treated rats.Moreover,EF combined with PF could induce a greater degree of injury than that caused by EF or PF alone in LPS-treated rats.Furthermore,EF or PF alone or in combination enhanced the LPS-stimulated inflammatory cytokine production,implying that IL-1β,which is processed and released by activating the NLRP3 inflammasome,is a specific indicator of EF-induced immune idiosyncratic hepatotoxicity.Thus,EF may induce liver injury through enhancing the LPS-mediated proinflammatory cytokine production and activating the NLRP3 inflammasome.In addition,the metabolomics analysis results showed that PF affected more metabolites in glycerophospholipid and sphingolipid metabolic pathways compared with EF in LPS model,suggesting that PF increased the responsiveness of the liver to LPS or other inflammatory mediators via modulation of multiple metabolic pathways.Therefore,EF and PF combination indicates traditional Chinese medicine incompatibility,considering that it induces idiosyncratic hepatotoxicity under immunological stress conditions.Yuan Gao Zhilei Wang Jinfa Tang Xiaoyi Liu Wei Shi Nan Qin Xiaoyan Wang Yu Pang Ruisheng Li Yaming Zhang Jiabo Wang Ming Niu Zhaofang Bai Xiaohe Xiao 2020Frontiers of Medicine2020,14,1:32
4Immunological synergistic mechanisms of trans-/cis-stilbene glycosides in Heshouwu-related idiosyncratic liver injury显示文摘Heshouwu is a traditional non-toxic Chinese medicine commonly used in the clinical setting;however,clinical cases of Heshouwu-induced hepatotoxicity have been frequently reported^([1]).Pharmacoepidemiological studies have found that Heshouwu-induced liver injury occurs only in a small fraction of individuals taking the drug;these patients presented with the typ-Lanzhi He Ping Yin Yakun Meng Jinfa Tang Tingting He Ming Niu Yuming Guo Yun Zhu Jing Jing Chunyu Li Zhijie Ma Jiabo Wang Zhaofang Bai Xiaohe Xiao 2017Science Bulletin2017,62,11:29
5Guidance for the clinical evaluation of traditional Chinese medicine-induced liver injury Issued by China Food and Drug Administration显示文摘1. Introduction Drug-induced liver injury (DILI), defined as liver injury caused by a drug and/or its metabolites, is a common clinical adverse drug reaction1–4. This type of injury can cause acute liver failure and even death in severe cases5.Xiaohe Xiao Jianyuan Tang Yimin Mao Xiuhui Li Jiabo Wang Chenghai Liu Kewei Sun Yong’an Ye Zhengsheng Zou Cheng Peng Ling Yang Yuming Guo Zhaofang Bai Tingting He Jing Jing Fengyi Li Na An 2019Acta Pharmaceutica Sinica B2019,9,3:22
6T cell–associated immunoregulation and antiviral effect of oxymatrine in hydrodynamic injection HBV mouse model显示文摘Although oxymatrine(OMT) has been shown to directly inhibit the replication of hepatitis B virus(HBV) in vitro, limited research has been done with this drug in vivo. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection.The infection was achieved by tail vein injection of a large volume of DNA solution. OMT(2.2, 6.7 and20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen(HBs Ag), hepatitis B e antigen(HBe Ag)and hepatitis B core antigen(HBc Ag). The immunoregulatory activity of OMT was evaluated by serum ELISA and flow cytometry. Results shows that OMT at 20 mg/kg inhibited HBV replication, and it was more efficient than entecavir(ETV) in the elimination of serum HBs Ag and intrahepatic HBc Ag. Inaddition, OMT accelerated the production of interferon-γ(IFN-γ) in a dose-dependent manner in CD4^+T cells. Our findings demonstrate the beneficial effects of OMT on the enhancement of immunological function and in the control of HBV antigens. The findings suggest this drug to be a good antiviral therapeutic candidate for the treatment of HBV infection.Xiuxiu Sang Ruilin Wang Yanzhong Han Cong’en Zhang Honghui Shen Zhirui Yang Yin Xiong Huimin Liu Shijing Liu Ruisheng Li Ruichuang Yang Jiabo Wang Xuejun Wang Zhaofang Bai Xiaohe Xiao 2017Acta Pharmaceutica Sinica B2017,7,3:20
7Cardamonin from a medicinal herb protects against LPS-induced septic shock by suppressing NLRP3 inflammasome显示文摘Aberrant activation of NLRP3 inflammasome has been implicated in the pathogenesis of diverse inflammation-related diseases, and pharmacological molecules targeting NLRP3 inflammasome are of considerable value to identifying potential therapeutic interventions. Cardamonin(CDN), the major active ingredient of the traditional Chinese medicinal herb Alpinia katsumadai, has exerted an excellent anti-inflammatory activity, but the mechanism underlying this role is not fully understood. Here, we show that CDN blocks canonical and noncanonical NLRP3 inflammasome activation triggered by multiple stimuli. Moreover, the suppression of CDN on inflammasome activation is specific to NLRP3, not to NLRC4 or AIM2 inflammasome. Besides, the inhibitory effect is not dependent on the expression of NF-κB-mediated inflammasome precursor proteins. We also demonstrate that CDN suppresses the NLRP3 inflammasome through blocking ASC oligomerization and speckle formation in a dose-dependent manner.Importantly, CDN improves the survival of mice suffering from lethal septic shock and attenuates IL-1βproduction induced by LPS in vivo, which is shown to be NLRP3 dependent. In conclusion, our results identify CDN as a broad-spectrum and specific inhibitor of NLRP3 inflammasome and a candidate therapeutic drug for treating NLRP3 inflammasome-driven diseases.Zhilei Wang Guang Xu Yuan Gao Xiaoyan Zhan Nan Qin Shubin Fu Ruisheng Li Ming Niu Jiabo Wang Youping Liu Xiaohe Xiao Zhaofang Bai 2019Acta Pharmaceutica Sinica B2019,9,4:19
8Measurement of ecological capital of Chinese terrestrial ecosystem based on remote sensing显示文摘The biosphere of the Earth is essential to human survival and development. The services of ecosystems are critical to the functioning of the Earth’s life-support system. They contribute to human welfare both directly and indirectly. Ecological capital refers to the sum of the direct biological resources value and the indirect ecosystem services value. It is necessary to estimate the ecological capital in order to bring it to the society and market economic system, and draw the social attention to ecological environment constructions. An estimation model for eco-logical capital based on remote sensing is presented in this paper. The parameters in the model are quantitatively measured using NOAA/AVHRR and other ancillary data, including the land cover types, the vegetation coverage, and the vegetation net primary productivity (NPP) of ter-restrial ecosystem. Based on the economic parameters in previously published studies and a few original calculations, the annual ecological capital of the entire terrestrial ecosystem of China is quantitatively estimated at 6.44 trillion (1012) yuan (RMB), and the spatial distribution of the eco-logical capital is also analyzed. Traditional ecological methods to ecological capital measurement are based on homogeneous plot scales, and the regional scaling is a key problem in their appli-cations. As the proposed remote sensing approach, it provides a new method to ecological capital measurement completely based on observation data. It can not only overcome the re-gional scaling problem easily, but also allows the ecological capital to be estimated objectively and spatial-explicitly.PAN Yaozhong SHI Peijun ZHU Wenquan GU Xiaohe FAN Yida LI Jing 2005Science China Earth Sciences2005,48,6:14
9Microcalorimetric investigation of effect of berberine alkaloids from Coptis chinensis Franch on intestinal diagnostic flora growth显示文摘The inhibitory effect of three berberine alkaloids (BAs) from Coptis chinensis Franch, a traditional Chinese medicinal (TCM) herb, on Bifidobacterium adolescentis growth was investigated by micro- calorimetry. The power-time curves of B. adolescentis with and without BAs were acquired, meanwhile the extent and duration of inhibitory effect on the metabolism were evaluated by the growth rate con- stant (k), half inhibitory ratio (IC50), maximum heat-output power (Pmax), peak time of maximum heat-output power (tp) and total heat production (Qt). k, Pmax and Qt decreased, and tp was prolonged with the increase of BAs concentration. The IC50 of BAs is 806 μg/mL for berberine, 341 μg/mL for cop- tisine and 236 μg/mL for palmatine. The sequence of antimicrobial activity of BAs is berberine < cop- tisine < palmatine. Combined with previous studies, it could be shown that the sequences of antim- icrobial activity of BAs on both Bacillus shigae and Escherichia coli are berberine > coptisine > pal- matine. The structure-function relationship of BAs indicates that the functional group methylenedioxy or methoxyl at C2 and C3 might be the major group inducing the activities of BAs on E. coli and B. adolescentis. Meanwhile, the substituent groups at C2, C3, C9 and C10 almost have equal effect on B. shigae.YAN Dan WEI Li XIAO XiaoHe ZHOU DanLei HAN YuMei 2009Chinese Science Bulletin2009,54,3:12
10Bavachin enhances NLRP3 inflammasome activation induced by ATP or nigericin and causes idiosyncratic hepatotoxicity显示文摘Psoraleae Fructus(PF)is a well-known traditional herbal medicine in China,and it is widely used for osteoporosis,vitiligo,and other diseases in clinical settings.However,liver injury caused by PF and its preparations has been frequently reported in recent years.Our previous studies have demonstrated that PF could cause idiosyncratic drug-induced liver injury(IDILI),but the mechanism underlying its hepatotoxicity remains unclear.This paper reports that bavachin isolated from PF enhances the specific stimuli-induced activation of the NLRP3 inflammasome and leads to hepatotoxicity.Bavachin boosts the secretion of IL-ip and caspase-1 caused by ATP or nigericin but not those induced by poly(I:C),monosodium urate crystal,or intracellular lipopolysaccharide.Bavachin does not affect AIM2 or NLRC4 inflammasome activation.Mechanistically,bavachin specifically increases the production of nigericin-induced mitochondrial reactive oxygen species among the most important upstream events in the activation of the NLRP3 inflammasome.Bavachin increases the levels of aspartate transaminase and alanine aminotransferase in serum and hepatocyte injury accompanied by the secretion of IL-ip via a mouse model of lipopolysaccharide-mediated susceptibility to IDILI.These results suggest that bavachin specifically enhances the ATP-or nigericin-induced activation of the NLRP3 inflammasome.Bavachin also potentially contributes to PF-induced idiosyncratic hepatotoxicity.Moreover,bavachin and PF should be evaded among patients with diseases linked to the ATP-or nigericin-mediated activation of the NLRP3 inflammasome,which may be a dangerous factor for liver injury.Nan Qin Guang Xu Yan Wang Xiaoyan Zhan Yuan Gao Zhilei Wang Shubin Fu Wei Shi Xiaorong Hou Chunyu Wang Ruisheng Li Yan Liu Jiabo Wang Haiping Zhao Xiaohe Xiao Zhaofang Bai 2021Frontiers of Medicine2021,15,4:9
11Short and long-term efficacy of combining Fuzhengliqi mixture with acupuncture in treatment of functional constipation显示文摘OBJECTIVE: To explore the short and long-term efficacy of combining Fuzhengliqi mixture (FLM) with acupuncture in treating functional constipation (FC). METHODS: The 560 patients with confirmed diagnosis of FC were randomly assigned to four groups: FLM group, acupuncture group, combined therapy group, and control group. There were 140 cases in each group. The FLM group was administered FLM 60 mL twice a day, while the acupuncture group was treated with acupuncture at acupoints Tianshu (ST 25), Shangjuxu (ST 37), Zusanli (ST 36), Dachangshu (BL 25), and Zhigou (TE 6) twice a day, the combined therapy group with FLM and acupuncture, and the control group was administered mosapride (5 mg thrice a day) and Macrogol 4000 (10 g twice a day). The treatment lasted 6 weeks. The defecation interval, stool property, constipation symptoms, and accompanying symptomswere recorded, graded, and scored.The gastrointestinal transit time (GITT) and motilin (MTL) level in serum and life quality score were detected at three time points (pre-treatment, at the end of treatment, and 60 weeks post-treatment). Moreover, the adverse reactions were also observed. RESULTS: In the FLM group 2 cases were eliminated for not taking medication strictly according to the research plan and 1 case was lost to follow-up, while 2 cases in the acupuncture group and 2 cases in the combined therapy group were lost to follow-up. Compared with those detected pre-treat- ment, the defecation interval, stool property, consti- pation symptom grade, accompanying symptom grade, and GITT were all decreased markedly at the end of treatment in every group, while the MTL levels in serum and life quality score were increased markedly (P<0.01), the above-mentioned detecting indices were better in the combined therapy group than those in other groups (P<0.05). Compared with the end of treatment, above-mentioned detecting indices all recurred significantly in the FLM group and control group 60 weeks post-treatment (P>0.05), but these indices recurred insignificantly in the acupuncture and combined therapy groups (P>0.05). The short and long-term total effective rates in the combined therapy group were significantly different from those in other groups (P<0.05 or P<0.01). No serious adverse reactions were found in four groups. CONCLUSION: Both FLM and acupuncture can significantly shorten the defecation interval and GITT, increase MTL levels in serum, decrease the scores of stool property, constipation symptoms, and accompanying symptoms in patients with FC to increase their life quality. The combined therapy is much better in long-term efficacy and the safety is also good, worth spreading in clinical practice.Chaoxian Zhang Like Guo Xiaofeng Guo Guangyan Li Xiaohe Guo 2013Journal of Traditional Chinese Medicine2013,33,1:8
12Clinical curative effect of electroacupuncture combined with Zhizhukuanzhong Capsules for treating gastroesophageal reflux disease显示文摘OBJECTIVE:To study the clinical curative effect,safety and mechanism of action of electroacupuncture combined with Zhizhukuanzhong capsules(ZZKZC) in treating gastroesophageal reflux disease(GERD).METHODS:A total of 480 patients with confirmed GERD were randomly divided into four groups:the electroacupuncture group,the ZZKZC group,the combined therapy group,and the control group,with 120 cases in each group.Each case in the electroacupuncture group was treated with electroacupuncture on Zusanli(ST36),Zhongwan(CV12),Neiguan(PC6),Taichong(LR3)and Gongsun(SP 4)once daily for 6 weeks.Each case in the ZZKZC group was treated with oral administration of 1.29 g ZZKZC three times daily.The combined therapy group had electroacupuncture and ZZKZC.The control group was given oral administration of 5 mg mosapride three times and 20 mg pantoprazole twice daily.The 24-hour intraesophageal total number of reflux episodes with pH <4(or bilirubin absorbance ≥ 0.14),the number of long-term(≥5 min) reflux episodes,the percentage of upright time,the percentage of supine time,the percentage of total time of pH <4(or bilirubin absorbance ≥0.14),endoscopic grading score,symptom score,quality of life score,and adverse reactions were observed before treatment,at the end of treatment and 54 weeks after treatment in the four groups.RESULTS:The 24-hour intraesophageal pH and bile reflux,endoscopic grading score and symptom score were all significantly decreased at the end of treatment in every group,while the scores of 8 dimensions of quality of life were all increased compared with those before treatment(P<0.01).All of these indices were better in the combined therapy group than those in the other groups(P<0.05).These indices did not significantly deteriorate in the combined therapy group and electroacupuncture group 54 weeks after treatment compared with the end of treatment(P>0.05);however,these indices all significantly deteriorated in the ZZKZC and control groups(P>0.05).The short and long-term total efficacy rates in the combined therapy group showed significant superiority to those in the other groups(P<0.05 or P<0.01).No serious adverse reactions were found in the four groups.CONCLUSION:Electroacupuncture and ZZKZC play an important role in inhibiting intraesophageal acid and bile reflux,decreasing the endoscopic grading score,and alleviating the symptoms of gastroesophageal reflux to improve the quality of life.However,the effect of combined treatment is more effective,with better security and long-term efficacy,and therefore,this combination treatment is appropriate for clinicaluse.Chaoxian Zhang Like Guo Xiaofeng Guo Xiaohe Guo Guangyan Li 2012Journal of Traditional Chinese Medicine2012,32,3:8
13Multiple Components are Integrated to Determine Leaf Complexity in Lotus japonicus显示文摘Transcription factors and phytohormones have been reported to play crucial roles to regulate leaf complexity among plant species. Using the compound-leafed species Lotus japonicus, a model legume plant with five visible leaflets, we characterized four independent mutants with reduced leaf complexity, proliferating floral meristem (pfm), proliferating floral organ-2 (pfo-2), fused leaflets1 (ful1) and umbrella leaflets (uml), which were further identified as loss-of-function mutants of Arabidopsis orthologs LEAFY (LFY ), UNUSUAL FLORAL ORGANS (UFO), CUP-SHAPED COTYLEDON 2 (CUC2) and PIN-FORMED 1 (PIN1), respectively. Comparing the leaf development of wild-type and mutants by a scanning electron microscopy approach, leaflet initiation and/or dissection were found to be affected in these mutants. Expression and phenotype analysis indicated that PFM/LjLFY and PFO/LjUFO determined the basipetal leaflet initiation manner in L. japonicus. Genetic analysis of ful1 and uml mutants and their double mutants revealed that the CUC2-like gene and auxin pathway also participated in leaflet dissection in L. japonicus, and their functions might influence cytokinin biogenesis directly or indirectly. Our results here suggest that multiple genes were interplayed and played conserved functions in controlling leaf complexity during compound leaf development in L. japonicus.Zhenhua Wang Jianghua Chen Lin Weng Xin Li Xianglin Cao Xiaohe Hu Da Luo Jun Yang 2013Journal of Integrative Plant Biology2013,55,5:6

15Effectiveness and safety of Chinese herbal medicines for hepatitis B virus-related acute-on-chronic liver failure:study protocol for a multicenter randomized controlled trial显示文摘OBJECTIVE:To conduct a multicenter randomized controlled trial of the efficacy of standardized Chinese herbal medicines(CHMs)against acuteon-chronic liver failure(ACLF)and provide reproducible and high-level evidence for clinical practice.METHODS:This is a prospective,multicenter,centrally randomized controlled trial.Patients diagnosed with hepatitis B virus-related ACLF(n=510)will be allocated to the standard medical therapy or CHM group at a 1∶1 ratio.Two CHMs will be used on the basis of the traditional Chinese medicine syndrome:Liangxue Jiedu granules for excess syndromes and Yiqi Jiedu granules for deficiency syndromes.The primary outcome is transplant-free survival at week 12.The secondary outcomes are(a)transplant-free survival at week 24,(b)liver function as assessed using the model for end-stage liver disease score at week 12,(c)liver function as assessed using the Child-Pugh score at week 12,and(d)the incidence of complications at week 12.DISCUSSION:The effectiveness and safety of CHM formulations will be assessed following treatment for ACLF.TRIAL REGISTRATION:The trial was registered at Clinical Trials.gov(NCT03577938)on June 24,2018.Zhang Ning Zhou Chao Wang Lifu He Tingting Wang Yao Wang Yan Bai Yunfeng Li Jun Xiao Xiaohe Gong Man 2020Journal of Traditional Chinese Medicine2020,40,6:5
16The self-regulation process and its mechanism of channels' bed changes in the Changjiang(Yangtze) Estuary in China显示文摘Recent bathymetric changes in the Changjiang Estuary under the influence of artificial regulation engineerings and basin reservoirs have been analyzed based on the maritime charts since 1997 and recent fieldworks. The results indicate a slight erosion of the channels in the upper and middle estuary, continuing deposition and seaward move of the mouth bar crest and intensifying erosion at the nearshore seabed. It is noteworthy that the morphological evolution caused by intensive human activities dominates over the changes from nature process.First, the riverbes are eroded overall in the South Branch(SB), the South Channel(SC) and the upper and middle reaches of the North Channel(NC). The nearshore seabed outside the river mouth is being eroded slightly, which is attributed to the declining sediment supply from the Changjiang Basin due to the construction of the Three Gorges Dam upstream. The sediment above the seabed is very active and coarsened, meanwhile, sand waves are becoming more distinct. Second, a deposition occurs in the North Brach(NB), the mouth of the NC, the mouth bars of the North Passage(NP) and the South Passage(SP) and especially the main channel of the NP, where it shows a massive siltation after the deep waterway project. The reasons for the recent changes are not only the dynamic structure in estuarine mouth bars, but also the supply of sediment resuspension in a local and offshore area. Meanwhile, the severe erosion and siltation in some reaches is related to the construction of estuarine engineerings. It is indicated that the Changjiang Estuary is gradually self-adjusted and adapting to the varying natural factors and intensive human activities. The study on the mechanism of self-regulation of the recent bathymetric changes in the Changjiang Estuary has important and practical significance.ZHANG Xiaohe LI Jiufa ZHU Wenwu CHENG Heqin CHEN Wei 2015Acta Oceanologica Sinica2015,34,7:5
17A quality evaluation strategy for Rhizoma coptidis from a variety of different sources using chromatographic fingerprinting combined with biological fingerprinting显示文摘Most of herbal medicines of different sources are used for the same treatment goal in clinic despite their tremendous differences of the quality.Because the clinical efficacy is closely related to the quality of medicines,the implementation of an effective quality control(QC)process is vital.Chemical methods based on content determination and chromatographic fingerprints(CFs)have been recommended as powerful tools.In spite of advances in QC,it is still difficult to determine that which of the chemical compositions can best reflect the correlation with the desired biological activity.Herein,we have focused on the biological activities of multi-source herbal medicines to establish an analytical method.By looking for correlations between the biological activities and their chemical compositions,the method can identify reasonable chemical indicators or chemical methods with biological activity information.In this study,high-performance liquid chromatography(HPLC)and microcalorimetry are combined as a useful method for evaluating the quality of Rhizoma coptidis from different sources.The results of biological fingerprints(BFs)showed that the antibacterial activity sequence of R.coptidis of different sources was Coptis teeta Wall.(CT)>Coptis chinensis Franch.(CC)>Coptis deltoidea C.Y.Cheng et Hsiao(CD).The'spectrum-activity'relationships between CFs and BFs were investigated using the canonical correlation analysis(CCA).Compared with the CCA result of CFs and BFs,the canonical correlation coefficient r1and r2were 0.9974 and 0.9752,respectively.It revealed that there are a close correlation between the spectrum-activity relationships and several of the major anti-bacterial components in the CFs,including jatrorrhizine,coptisine,palmatine,and berberine.Of course,R.coptidis was only a representative of multisource medical plants.The result of the current study will provide an effective reference for evaluating the quality of multisource herbal medicines.LI JunXian YAN Dan MA LiNa XIONG Yin YAN ChunXia LI BaoCai PENG Cheng XIAO XiaoHe 2013Chinese Science Bulletin2013,58,33:5
18MULTI-SCALE GAUSSIAN PROCESSES MODEL显示文摘A novel model named Multi-scale Gaussian Processes (MGP) is proposed. Motivated by the ideas of multi-scale representations in the wavelet theory, in the new model, a Gaussian process is represented at a scale by a linear basis that is composed of a scale function and its different translations. Finally the distribution of the targets of the given samples can be obtained at different scales. Compared with the standard Gaussian Processes (GP) model, the MGP model can control its complexity conveniently just by adjusting the scale pa-rameter. So it can trade-off the generalization ability and the empirical risk rapidly. Experiments verify the fea-sibility of the MGP model, and exhibit that its performance is superior to the GP model if appropriate scales are chosen.Zhou Yatong Zhang Taiyi Li Xiaohe 2006Journal of Electronics(China)2006,23,4:4
19Rhubarb-based Chinese herbal formulae for hepatic encephalopa-thy:a systematic review and Meta-analysis显示文摘OBJECTIVE: To evaluate the effectiveness and safety of rhubarb-based Chinese herbal formulae(RCHF), which are widely used to treat hepatic encephalopathy(HE) in China.METHODS: Nine online databases were searched from inception to November 22, 2016. Eligible studies were randomized controlled trials of Traditional Chinese Medicine(TCM) treatment for adult patients(≥ 18 years old) with HE. Outcomes such as mortality rate, clinical response rate, blood ammonia level, and alanine aminotransferase were evaluated between TCM group and control group.RESULTS: Thirty studies involving 2661 HE patients were analyzed. Most studies used RCHF treatment.Compared with conventional treatment as usual,lactulose, and vinegar, RCHF were associated with significant improvement in clinical response rate[risk ratio(RR) = 1.33, 95% confidence interval(CI) =1.25, 1.43, I2= 0%; RR = 1.26, 95% CI = 1.14, 1.38, I2=22%; and RR = 1.19, 95% CI = 1.06, 1.33, I2= 0%, respectively] and significant reductions in levels of blood ammonia and alanine aminotransferase. Only minor RCHF-associated adverse events, such as abdominal pain(0.3%), anal tenesmus(0.3%), and diarrhea(2.3%), were reported, and there were no significant differences in these events between the treatment group and the three types of control group.CONCLUSION: The findings suggest that RCHF may be an alternative treatment option for HE patients. More rigorous multicenter studies with larger samples and longer observational periods are needed to confirm these findings.Zhang Ning Zhou Shuangnan Xiao Xiaohe Wanq Zhen Bai Yunfeng He Tingting Zhou Chao Wang Yao Kun Zhou Wang Zhongxia Liu Bing Larry J.Prokop Matthew C.Hernandez Li Jun Gong Man 2017Journal of Traditional Chinese Medicine2017,37,6:3
20Clinical characteristics of 96 patients with drug-induced acute liver failure:a comparison between Traditional Chinese and Western Medicine显示文摘OBJECTIVE: To compare the causes, clinical symptoms, laboratory test results, and prognosis in patients with acute liver failure(ALF) induced by traditional Chinese medicines(TCM) and by Western Medicines(WM).METHODS: The medical histories of patients who were diagnosed with drug-induced ALF(DALF)(n =96) after hospitalization in the 302 Military Hospital between January 2010 and December 2015 were retrospectively examined.RESULTS: Fifty-eight of the 96 DALF patients(60.4%) had a hepatocellular pattern of DALF, 16 patients(16.7%) had a cholestatic pattern, and 22 patients(22.9%) had a mixed pattern. DALF resolved in 24 patients(25.0%). Twenty-five patients(26.0%)developed chronic liver injury, 43 patients(44.8%)died, and 4 patients(4.2%) underwent liver transplantation. There were 42 ALF patients(43.8%) who received WM, and 32 ALF patients(33.3%) who received TCM. TCM-induced ALF patients had a higher average age [42.4 ± 18.4) vs(33.5 ± 17.9) years,P = 0.04] and higher creatinine and urine nitrogen levels [(155.2 ± 108.8) vs(97.5 ± 130.4) mmol/L, P =0.047;(9.1 ± 7.7) vs(4.3 ± 5.0) mmol/L, P = 0.002, respectively]. Patients with TCM-induced ALF exhibited an increased risk of renal injury [odds ratio(OR),3.75; 95% confidence interval(CI), 1.330-10.577].The 14 patients with TCM-induced ALF who died exhibited higher creatinine levels than the 18 patients with TCM-induced ALF patients who survived[(218.7 ± 111.6) vs(105.8 ± 78.4) mmol/L, P =0.002]. They were also more likely to exhibit ascites(85.7% vs 44.4%, P = 0.017) and hepatorenal syndrome(78.6% vs 22.2%, P = 0.002).CONCLUSION: TCM-induced ALF was more likely to be accompanied by renal injury than was WM-induced ALF, especially in TCM-induced ALF patients who died.He Tingting Zhu Yun Wang Jiabo Gong Man Wang Ruilin Niu Ming Jing Jing Wang Lifu Wang Zhongxia Zhang Ning Bai Zhaofang Bai Yunfeng Li Yonggang Xiao Xiaohe 2017Journal of Traditional Chinese Medicine2017,37,3:3
