With scientific endeavor and further exploration, we came to realize that there are great differences between H&TM and synthetic drugs in many aspects, such as medical theory, medication experience, compatibility, processing, toxicological characteristics, and safety evaluating requirements. In the current preclinical models for synthetic drugs, the safety assessment results of some conventional deemed 'nontoxic' H&TM were not well consistent with clinical situations, which resulted in major difficulties to understand the mechanisms and guide the safe and rational uses of these H&TM. Thus, based on the traditional Chinese medicine toxicity theory called You Gu Wu Yun, this paper introduces a novel safety assessment strategy for H&TM, named as disease-based toxicology. It aims to cognize the relativity and susceptibility of the toxicity of H&TM, and then to enhance controllability in new drug development and clinical applications. It also provides a theoretical practice for the traditional Chinese medicine toxicity theory and a methodological promotion for the future development of the precision toxicology for H&TM.展开更多

The R&D of CTHM is thought to be an important pathway for new drug discovery. Since1949, about 140 approved new drugs have been developed, among which about 80 originated directly or indirectly from medicinal plants. CTHM has gained interest from the international medical, biomedical, and pharmaceutical institutions as a valuable source of potential medicines. For the modernization of CMM and innovative research of CTHM, there are following challenges to be faced: (1) to evaluate the efficacy, pharmacological properties, action mechanism, and active chemical constituents; (2) to develop new methodologies for the quality and safety of CTHM; (3) to apply new '-omics' techniques to accelerate drug discoveries developed from CTHM; and (4) to apply international practices including good agricultural practice, good manufacturing practice, good laboratory practice, and good clinical practice in the R&D of CTHM.展开更多

The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-KB and tumor necrosis factor-a and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis.展开更多

Very few studies have addressed the regulation of Nogo-A in neonatal rats following HIBD. However, numerous studies have shown that ephedrine accelerates neuronal remodeling and promotes recovery of neural function in neonatal rats following HIBD. OBJECTIVE: To investigate the effects of ephedrine on expression of Nogo-A and synaptophysin in brain tissues of neonatal rats following HIBD. DESIGN, TIME AND SETTING: A completely randomized, controlled study was performed at the Immunohistochemistry Laboratory of the Research Institute of Pediatrics, Children's Hospital of Chongqing Medical University from August 2008 to March 2009. MATERIALS: Ephedrine hydrochloride (Chifeng Pharmaceutical Group, China), rabbit anti-Nogo-A polyclonal antibody (Abcam, UK), and rabbit anti-synaptophysin polyclonal antibody (Lab Vision, USA) were used in this study. METHODS: A total of 96 healthy, neonatal, Sprague Dawley rats were randomly assigned to three groups (n = 32): sham operation, HIBD, and ephedrine. The HIBD model was established by permanent occlusion of the left common carotid artery, followed by 2 hours of hypoxia (8% oxygen and 92% nitrogen). In the sham operation group, the left common carotid artery was exposed, but was not ligated or subjected to hypoxia. Rats in the ephedrine group were intraperitoneally injected with ephedrine immediately following HIBD, with 1.5 mg/kg each time. Rats in the sham operation and HIBD groups were injected with an equal volume of saline. All neonatal rats were treated once daily for 7 days. MAIN OUTCOME MEASURES: Histopathological damage to the cortex and hippocampus was determined by hematoxylin-eosin staining. Expression of Nogo-A and synaptophysin was detected using immunohistochemical staining. RESULTS: Neuronal degeneration and edema were observed in the hypoxJc-Jschemic cortex and hippocampus by hematoxylin-eosin staining. Compared with the sham operation group, the levels of Nogo-A significantly increased in the HIBD group at various time points (P 〈 0.01). Nogo-A expression was significantly reduced in the ephedrine group compared with the HIBD group (P 〈 0.01). Synaptophysin expression was significantly decreased in the hypoxic-ischemJc cortex, compared with the sham operation group (P 〈 0.01). Synaptophysin levels were significantly increased in the ephedrine group, compared with the HIBD group (P 〈 0.01). CONCLUSION: Altered Nogo-A expression was associated with inversely altered synaptophysin expression. The use of ephedrine normalized expression levels of Nogo-A and synaptophysin following HIBD.展开更多

Methods: To identify randomized controlled trials, an electronic search has been conducted through databases as follows: PubMed, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biological Medicine Database, China National Knowledge Infrastructure Database, Chinese Scientific Journal Database, and WanFang Digital Periodicals Database.Methodological quality was evaluated by Cochrane Collaboration's tool which is able to assess the risk of bias in Review Manager Software.What's more, meta-analysis was performed by using Cochrane Collaboration's RevMan 5.2 software,(Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen, and Denmark). Dichotomous data were analyzed by using relative risk(RR) and 95% confidence interval(CI).Continuous variables were analyzed using weighted mean differences(WMDs) and 95% CI. Subgroup analysis was performed by the type of medicine which was used in the experimental group. Results: This meta-analysis includes 11 randomized control trials with 818 patients.Compared to the control group(RR: 1.14, 95% CI: [1.03, 1.26], P = 0.009 and WMD:-2.09, 95% CI: [-3.58,-0.18]), the experimental group had a significant higher clinical efficacy rate and relatively lower Hamilton Depression Rating Scale(HAM-D) score. For clinical efficacy rate, the results varied depending on the detail treatment measures of the experimental group. In the experimental group with TCHM,no significant difference was observed(RR: 1.14, 95% CI: [0.97, 1.33]), while in the experimental group combined with western medicine,a significant difference in the clinical efficacy rate between the experimental group and control group showed up(RR: 1.15, 95% CI: [1.01,1.32], P = 0.04). For the HAM-D score, subgroup analyses revealed that the pure TCHM therapy was not associated with significant HAM-D score reduction compared to the control group(WMD:-2.48, 95% CI: [-6.00,1.03], P = 0.17). However, in the experimental group where western medicine was added to, the HAM-D score decreased statistically compared to the control group(WMD:-1.88, 95% CI: [-3.58,-0.18], P = 0.03). There is no serious adverse event in both groups. Conclusions: Combination therapy of TCHM and western medicine is more effective in treating PD in terms of clinical efficacy rate. However, the results should be interpreted with caution due to the mediocre methodological quality of the included trials.展开更多

Methods: Keywords for dementia and traditional herbal medicine for treating dementia were used to extract scientific articles from the Web of Science database from January 2000 to July 2010. A co- occurrence matrix was created based on the concurrent set of author's keywords occurring in each scientific article, and technology network maps were created from similarity index matrices. Results: Twenty specialized research areas were identified in the dementia field, and the relationship strength was 0.2-0.6. Many research fields were associated with diagnosis and risk factors for dementia. Additionally, the mechanism or cause of dementia is an actively studied field. Traditional herbal medicine for treating dementia was located on a map near the cortical dementia diagnosis and therapy, and frontotemporal dementia research field with a relationship strength of 0.53 and 0.31-0.33 respectively, which demonstrates that traditional herbal medicine for dementia occupies an independent research area with a relationship to existing scientific research fields. Conclusion: Traditional herbal medicine can provide an alternative and complementary approach for treating dementia as evidenced by a scientific mapping analysis.展开更多

Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some susceptible individuals, necessitating a stringent pretreatment evaluation of the risk/benefit ratio, based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials.展开更多

TCM has certain treatment advantages for patients suffering from various complex diseases. However, due to the complex nature of TCM, it remains difficult to unveil such holistic medicine by the current reductionism research strategies, which treat both herbal ingredients and targets in isolation. Recently, an emerging network pharmacology approach has been introduced to tackle this bottleneck problem. A TCM-derived novel therapeutic concept, "network target", which is different from the Western medicine's "onetarget" concept, has been proposed from China. The network target strategy is able to illustrate the complex interactions among the biological systems, drugs, and complex diseases from a network perspective, and thus provides an innovative approach to access ancient remedies in a precision manner and at a systematic level, which also highlights TCM's potential in current medical systems.展开更多

文摘The safety issue on herbal and traditional medicines(H&TM) is one of the most challenging problems and serious concern worldwide. With scientific endeavor and further exploration, we came to realize that there are great differences between H&TM and synthetic drugs in many aspects, such as medical theory, medication experience, compatibility, processing, toxicological characteristics, and safety evaluating requirements. In the current preclinical models for synthetic drugs, the safety assessment results of some conventional deemed 'nontoxic' H&TM were not well consistent with clinical situations, which resulted in major difficulties to understand the mechanisms and guide the safe and rational uses of these H&TM. Thus, based on the traditional Chinese medicine toxicity theory called You Gu Wu Yun, this paper introduces a novel safety assessment strategy for H&TM, named as disease-based toxicology. It aims to cognize the relativity and susceptibility of the toxicity of H&TM, and then to enhance controllability in new drug development and clinical applications. It also provides a theoretical practice for the traditional Chinese medicine toxicity theory and a methodological promotion for the future development of the precision toxicology for H&TM.
文摘This review is briefly to recall the history of research and development (R&D) of Chinese materia medica (CMM) and to discuss the challenges of Chinese traditional and herbal medicines (CTHM) facing the modern science and technology. The R&D of CTHM is thought to be an important pathway for new drug discovery. Since1949, about 140 approved new drugs have been developed, among which about 80 originated directly or indirectly from medicinal plants. CTHM has gained interest from the international medical, biomedical, and pharmaceutical institutions as a valuable source of potential medicines. For the modernization of CMM and innovative research of CTHM, there are following challenges to be faced: (1) to evaluate the efficacy, pharmacological properties, action mechanism, and active chemical constituents; (2) to develop new methodologies for the quality and safety of CTHM; (3) to apply new '-omics' techniques to accelerate drug discoveries developed from CTHM; and (4) to apply international practices including good agricultural practice, good manufacturing practice, good laboratory practice, and good clinical practice in the R&D of CTHM.

文摘Buyang Huanwu Decoction fraction extracted from Buyang Huanwu Decoction contains saponins of Astragalus, total paeony glycoside and safflower flavones. The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-KB and tumor necrosis factor-a and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis.

文摘BACKGROUND: Central nervous system axons regenerate poorly following neonatal hypoxic-ischemic brain damage (HIBD), partly due to inhibitors, such as Nogo-A. Very few studies have addressed the regulation of Nogo-A in neonatal rats following HIBD. However, numerous studies have shown that ephedrine accelerates neuronal remodeling and promotes recovery of neural function in neonatal rats following HIBD. OBJECTIVE: To investigate the effects of ephedrine on expression of Nogo-A and synaptophysin in brain tissues of neonatal rats following HIBD. DESIGN, TIME AND SETTING: A completely randomized, controlled study was performed at the Immunohistochemistry Laboratory of the Research Institute of Pediatrics, Children's Hospital of Chongqing Medical University from August 2008 to March 2009. MATERIALS: Ephedrine hydrochloride (Chifeng Pharmaceutical Group, China), rabbit anti-Nogo-A polyclonal antibody (Abcam, UK), and rabbit anti-synaptophysin polyclonal antibody (Lab Vision, USA) were used in this study. METHODS: A total of 96 healthy, neonatal, Sprague Dawley rats were randomly assigned to three groups (n = 32): sham operation, HIBD, and ephedrine. The HIBD model was established by permanent occlusion of the left common carotid artery, followed by 2 hours of hypoxia (8% oxygen and 92% nitrogen). In the sham operation group, the left common carotid artery was exposed, but was not ligated or subjected to hypoxia. Rats in the ephedrine group were intraperitoneally injected with ephedrine immediately following HIBD, with 1.5 mg/kg each time. Rats in the sham operation and HIBD groups were injected with an equal volume of saline. All neonatal rats were treated once daily for 7 days. MAIN OUTCOME MEASURES: Histopathological damage to the cortex and hippocampus was determined by hematoxylin-eosin staining. Expression of Nogo-A and synaptophysin was detected using immunohistochemical staining. RESULTS: Neuronal degeneration and edema were observed in the hypoxJc-Jschemic cortex and hippocampus by hematoxylin-eosin staining. Compared with the sham operation group, the levels of Nogo-A significantly increased in the HIBD group at various time points (P 〈 0.01). Nogo-A expression was significantly reduced in the ephedrine group compared with the HIBD group (P 〈 0.01). Synaptophysin expression was significantly decreased in the hypoxic-ischemJc cortex, compared with the sham operation group (P 〈 0.01). Synaptophysin levels were significantly increased in the ephedrine group, compared with the HIBD group (P 〈 0.01). CONCLUSION: Altered Nogo-A expression was associated with inversely altered synaptophysin expression. The use of ephedrine normalized expression levels of Nogo-A and synaptophysin following HIBD.

文摘Objective: The objective of this study is to evaluate the effectiveness and safety of traditional Chinese herbal medicine(TCHM) in treatment of perimenopausal depression(PD) in China. Methods: To identify randomized controlled trials, an electronic search has been conducted through databases as follows: PubMed, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biological Medicine Database, China National Knowledge Infrastructure Database, Chinese Scientific Journal Database, and WanFang Digital Periodicals Database.Methodological quality was evaluated by Cochrane Collaboration's tool which is able to assess the risk of bias in Review Manager Software.What's more, meta-analysis was performed by using Cochrane Collaboration's RevMan 5.2 software,(Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen, and Denmark). Dichotomous data were analyzed by using relative risk(RR) and 95% confidence interval(CI).Continuous variables were analyzed using weighted mean differences(WMDs) and 95% CI. Subgroup analysis was performed by the type of medicine which was used in the experimental group. Results: This meta-analysis includes 11 randomized control trials with 818 patients.Compared to the control group(RR: 1.14, 95% CI: [1.03, 1.26], P = 0.009 and WMD:-2.09, 95% CI: [-3.58,-0.18]), the experimental group had a significant higher clinical efficacy rate and relatively lower Hamilton Depression Rating Scale(HAM-D) score. For clinical efficacy rate, the results varied depending on the detail treatment measures of the experimental group. In the experimental group with TCHM,no significant difference was observed(RR: 1.14, 95% CI: [0.97, 1.33]), while in the experimental group combined with western medicine,a significant difference in the clinical efficacy rate between the experimental group and control group showed up(RR: 1.15, 95% CI: [1.01,1.32], P = 0.04). For the HAM-D score, subgroup analyses revealed that the pure TCHM therapy was not associated with significant HAM-D score reduction compared to the control group(WMD:-2.48, 95% CI: [-6.00,1.03], P = 0.17). However, in the experimental group where western medicine was added to, the HAM-D score decreased statistically compared to the control group(WMD:-1.88, 95% CI: [-3.58,-0.18], P = 0.03). There is no serious adverse event in both groups. Conclusions: Combination therapy of TCHM and western medicine is more effective in treating PD in terms of clinical efficacy rate. However, the results should be interpreted with caution due to the mediocre methodological quality of the included trials.

文摘Objective: To identify the position of traditional herbal medicine in dementia research field using mapping technology. Methods: Keywords for dementia and traditional herbal medicine for treating dementia were used to extract scientific articles from the Web of Science database from January 2000 to July 2010. A co- occurrence matrix was created based on the concurrent set of author's keywords occurring in each scientific article, and technology network maps were created from similarity index matrices. Results: Twenty specialized research areas were identified in the dementia field, and the relationship strength was 0.2-0.6. Many research fields were associated with diagnosis and risk factors for dementia. Additionally, the mechanism or cause of dementia is an actively studied field. Traditional herbal medicine for treating dementia was located on a map near the cortical dementia diagnosis and therapy, and frontotemporal dementia research field with a relationship strength of 0.53 and 0.31-0.33 respectively, which demonstrates that traditional herbal medicine for dementia occupies an independent research area with a relationship to existing scientific research fields. Conclusion: Traditional herbal medicine can provide an alternative and complementary approach for treating dementia as evidenced by a scientific mapping analysis.

文摘Traditional Chinese Medicine (TCM) is popular around the world and encompasses many different practices with parti-cular emphasis on herbal TCM. Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some susceptible individuals, necessitating a stringent pretreatment evaluation of the risk/benefit ratio, based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials.

文摘Traditional Chinese medicine(TCM) holds a holistic theory, and specializes in balancing disordered human body using numerous natural products, particularly Chinese herbal formulae. TCM has certain treatment advantages for patients suffering from various complex diseases. However, due to the complex nature of TCM, it remains difficult to unveil such holistic medicine by the current reductionism research strategies, which treat both herbal ingredients and targets in isolation. Recently, an emerging network pharmacology approach has been introduced to tackle this bottleneck problem. A TCM-derived novel therapeutic concept, "network target", which is different from the Western medicine's "onetarget" concept, has been proposed from China. The network target strategy is able to illustrate the complex interactions among the biological systems, drugs, and complex diseases from a network perspective, and thus provides an innovative approach to access ancient remedies in a precision manner and at a systematic level, which also highlights TCM's potential in current medical systems.
