Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease around the world, and it often coexists with insulin resistance-related diseases including obesity, diabetes, hyperlipidemia, and hypertension, which seriously threatens human health. Better prevention and treatment strategies are required to improve the impact of NAFLD. Although needle biopsy is an effective tool for diagnosing NAFLD, this method is invasive and difficult to perform. Therefore, it is very important to develop more efficient approaches for the early diagnosis of NAFLD. Traditional Chinese medicine (TCM) can play a certain role in improving symptoms and protecting target organs, and its mechanism of action needs to be further studied. Metabolomics, the study of all metabolites that is thought to be most closely associated with the patients’ characters, can provide useful clinically biomarkers that can be applied to NAFLD and may open up new methods for diagnosis. Metabolomics technology is consistent with the overall concept of TCM, and it can also be used as a potential mechanism to explain the effects of TCM by measuring biomarkers by metabolomics. Based on PubMed/MEDLINE and other databases, this paper retrieved relevant literature NAFLD and TCM intervention in NAFLD using metabolomics technology in the past 5 years were searched, and the specific metabolites associated with the development of NAFLD and the potential mechanism of Chinese medicine on improving symptoms were summarized.

Abstract
Pueraria flavone (PF), the main component of Pueraria lobata, is a traditional Chinese medicine used for the treatment of cardiovascular and cerebrovascular diseases; however, it exhibits low oral bioavailability because of its poor membrane permeability. In this study, PF-loaded sodium deoxycholate-decorated liposomes (SDC-Lips) were prepared using the reverse-phase evaporation method and optimised using the Box-Behnken design method. The morphology, particle size, zeta potential, and entrapment efficiency of these PF-loaded SDC-Lips were evaluated. The release behaviours of PF-loaded SDC-Lips in simulated gastric and intestinal fluids were consistent with the Weibull kinetic model. In situ intestinal perfusion studies showed that the absorption characteristics of free PF in rats were mainly passive diffusion and partly active transport, and the duodenum was the main absorption site. After encapsulated with SDC-Lips, the absorption of PF increased significantly. The in vivo pharmacokinetic parameters of area under the plasma concentration-time curve (AUC)(0 → 12 h) and AUC(0 → ∞) of PF-loaded SDC-Lips after intragastric administration were 1.34-fold and 1.543-fold, respectively. Overall, the PF-loaded SDC-Lips improved the oral absorption of PF by increasing its solubility and might be considered a promising formulation strategy for prolonging the biological activity time of PF.

Puerarin Restores Autophagosome-Lysosome Fusion to Alleviate Cadmium-Induced Autophagy Blockade via Restoring the Expression of Rab7 in Hepatocytes. Front Pharmacol 2021; 12:632825. [PMID: 33935722 PMCID: PMC8079953 DOI: 10.3389/fphar.2021.632825] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 03/01/2021] [Indexed: 01/02/2023] Open
Abstract
Autophagic dysfunction is one of the main mechanisms by which the environmental pollutant cadmium (Cd) induces cell injury. Puerarin (Pue, a monomeric Chinese herbal medicine extract) has been reported to alleviate Cd-induced cell injury by regulating autophagy pathways; however, its detailed mechanisms are unclear. In the present study, to investigate the detailed mechanisms by which Pue targets autophagy to alleviate Cd hepatotoxicity, alpha mouse liver 12 (AML12) cells were used to construct a model of Cd-induced hepatocyte injury in vitro. First, the protective effect of Pue on Cd-induced cell injury was confirmed by changes in cell proliferation, cell morphology, and cell ultrastructure. Next, we found that Pue activated autophagy and mitigated Cd-induced autophagy blockade. In this process, the lysosome was further activated and the lysosomal degradation capacity was strengthened. We also found that Pue restored the autophagosome-lysosome fusion and the expression of Rab7 in Cd-exposed hepatocytes. However, the fusion of autophagosomes with lysosomes and autophagic flux were inhibited after knocking down Rab7, and were further inhibited after combined treatment with Cd. In addition, after knocking down Rab7, the protective effects of Pue on restoring autophagosome-lysosome fusion and alleviating autophagy blockade in Cd-exposed cells were inhibited. In conclusion, Pue-mediated alleviation of Cd-induced hepatocyte injury was related to the activation of autophagy and the alleviation of autophagy blockade. Pue also restored the fusion of autophagosomes and lysosomes by restoring the protein expression of Rab7, thereby alleviating Cd-induced autophagy blockade in hepatocytes.

Abstract
This study aims at developing and characterizing the puerarin dry powder inhaler (DPI) formulations for pulmonary delivery. The inhalable particles size (<2 μm) was accomplished by micronization and its morphology was examined by scanning electron microscopy (SEM). The puerarin-excipient interaction in powder mixtures was analyzed by using Fourier transform infrared spectroscopy (FTIR), Raman confocal microscopy, X-Ray powder Diffraction (XRD), and differential scanning calorimetry (DSC) methods. Using a Twin stage impinger (TSI), the in-vitro aerosolization of the powder formulations was carried out at a flow rate of 60 L/min and the drug was quantified by employing a validated HPLC method. No significant interactions between the drug and the excipients were observed in the powder formulations. The fine particle fraction (FPF) of the drug alone was 4.2% which has increased five to six-fold for the formulations with aerosolization enhancers. Formulation containing lactose as large carriers produced 32.7% FPF, which further increased with the addition of dispersibility enhancers, leucine and magnesium stearate (40.8% and 41.2%, respectively). The Raman and FTIR techniques are very useful tool for understanding structural integrity and stability of the puerarin in the powder formulations. The puerarin was found to be compatible with the excipients used and the developed DPI formulation may be considered as an efficient formulation for pulmonary delivery for the management of various diseases at a very low dose.

Abstract
Medicinal plants are a vital source of natural products (NPs) that can cure cancer through modulation of different pathways, including oxidative stress, extrinsic and intrinsic apoptosis, cell cycle, inflammation, NF-kB, PI3K/AKT/mTOR, AMPK (JNK), MEK/ERK (Raf)-MEK-ERK and autophagy. Puerarin (Pue), an important NP belonging to the isoflavone glycoside group, is derived from Pueraria lobata (Willd.) Ohwi, Pueraria thomsonii Benth, and Pueraria tuberosa (Willd.). This NP was approved by the Chinese Ministry of Health for the treatment of different diseases in 1993, but it was also later reported to exhibit anticancer activity. Pue causes cancer cells death through modulation of different mechanisms including oxidative stress, intrinsic and extrinsic, Survivin and XIAP, PI3K/AKT/mTOR, Ras-Raf-MEK-ERK, JNK, cell cycle, AMPK, NF-kB, inflammation and autophagy pathways. Therefore, this review compiles for the first time the studies about the anticancer mechanism of Pue and provides comprehensive information about the anticancer effects of Pue. This review may serve as a basis for future research and clinical treatment.

Abstract
As the worldwide population ages, the morbidity of neurodegenerative, cardiovascular, cerebrovascular, and endocrine diseases, such as diabetes and osteoporosis, continues to increase. The etiology of geriatric diseases is complex, involving the interaction of genes and the environment, which makes effective treatment challenging. Traditional Chinese medicine, unlike Western medicine, uses diverse bioactive ingredients to target multiple signaling pathways in geriatric diseases. Radix puerariae is one of the most widely used ancient traditional Chinese medicines and is also consumed as food. This review summarizes the evidence from in vivo and in vitro studies of the pharmacological effects of the main active components of the tuber of Radix puerariae on geriatric diseases.

Abstract
Puerarin 6″-O-xyloside (PRX) is a major compound found in the root of the Pueraria lobata (Willd.) Ohwi. The present study aimed to investigate the antitumor activity of PRX against colon cancer and examine its possible mechanism. In the present study, the anti-proliferative effects of PRX against colon cell lines (SW480, LoVo and HCT-116) were evaluated using a Cell Counting Kit-8 assay, and the half maximal inhibitory concentration values of the SW480, LoVo and HCT-11 cells were 37.114, 49.213 and 43.022 µg/ml, respectively. Furthermore, the apoptosis of SW480 cells was detected using flow cytometry with Annexin V-fluorescein isothiocyanate/propidium iodide staining. Subsequently, western blot analysis was performed to examine the expression of proteins associated with apoptosis, invasion and metastasis of tumors. The results showed that PRX possessed antitumor activity against colon cancer cell lines in a dose-dependent and time-dependent manner. In addition, PRX significantly upregulated the expression levels of cleaved (c)-caspase-3, c-caspase-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein and phosphorylated c-Jun terminal kinase, and downregulated the expression levels of Bcl-2, matrix metalloproteinase (MMP)-3, MMP-9 and vascular endothelial growth factor (P<0.01). Therefore, the present study demonstrated the PRX exerted antitumor activity against colon cancer cell lines and that the anticancer mechanisms of PRX may be associated with the induction of mitochondria-mediated intrinsic apoptosis, and inhibition of tumor invasion and metastasis. The present study provides a scientific basis for the clinical use of PRX for the treatment of colon cancer.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2017; 25:100-117. [PMID: 28190464 DOI: 10.1016/j.phymed.2017.01.002] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2015] [Revised: 12/22/2016] [Accepted: 01/05/2017] [Indexed: 06/06/2023]
Abstract
BACKGROUND Currently, many trials have been conducted to investigate the beneficial and harmful effects of Salvia miltiorrhiza depside salts for infusion for treating patients with angina pectoris. It is important to systematically and criticallyevaluate the existing literature into providing a pooled effect to examine outcomes of angina pectoris with Salvia miltiorrhiza depside salts for infusion. PURPOSE A systematic review and meta-analysis were performed to determine the clinical curative effect and safety of Salvia miltiorrhiza depside salts for infusion for angina pectoris and provide clear evidence to inform clinical practice. METHOD The Cochrane Library, MEDLINE, EMBASE, and other four electronic Chinese databases were searched to identify relevant randomized controlled trials. Methodological quality and reporting quality of eligible studies was evaluated by using the Cochrane risk-of-bias tool and CONSORT for traditional Chinese medicine respectively. Meta-analysis was performed by RevMan 5.3 software. RESULT Fifty-six randomized controlled trials involving 5503 patients were included. Most of the trials were classified as having an unclear risk of bias because of poor reported methodology. The main outcomes are improvements in angina symptoms, ECG improvement and reduction of nitroglycerin use. CHD mortality or rate of CHD events was not reported in any trial. Meta-analysis showed that Salvia miltiorrhiza depside salts for infusion combined with conventional treatment was better than conventional treatment alone in improving angina symptoms (RR= 1.28, 95% CI 1.24 to 1.31, p < 0.00001), the frequency of angina attack (time/week)(WMD=-1.47, 95% CI -2.16 to -0.78), reducing clinical symptom scores (WMD=-0.55, 95% CI -0.57 to -0.53, p < 0.000011), increasing physical limitation scores (WMD= 7.68, 95% CI 1.48 to 13.88, p = 0.02), improving ECG (RR= 1.32,95% CI 1.27 to 1.38, p < 0.00001) and reducing dosage of nitroglycerin (RR= 1.50, 95% CI: 1.26 to 1.77, p < 0.00001). In addition, Egger's regression tests was found there was publication bias (Kendall' tau= 0.36, p < 0.01). CONCLUSION The current systematic review indicates relevant evidence for Salvia miltiorrhiza depside salts for infusion combined with conventional treatments treating patient with angina pectoris. However, the results should be interpreted with caution due to the low methodological quality, the risk of publication bias, lack of important clinically relevant outcomes and inadequate reporting on adverse events of the included trials. International methodological and reporting standards could help researchers conduct well designed trials and generate better evidence for Salvia miltiorrhiza depside salts for infusion.

Abstract
Puerarin, a known isoflavone, is commonly found as a Chinese herb medicine. It is widely used in China to treat cardiac diseases such as angina, cardiac infarction and arrhythmia. However, its cardioprotective mechanism remains unclear. In this study, puerarin significantly prolonged ventricular action potential duration (APD) with a dosage dependent manner in the micromolar range on isolated rat ventricular myocytes. However, submicromolar puerarin had no effect on resting membrane potential (RMP), action potential amplitude (APA) and maximal velocity of depolarization (Vmax) of action potential. Only above the concentration of 10 mM, puerarin exhibited more aggressive effect on action potential, and shifted RMP to the positive direction. Millimolar concentrations of puerarin significantly inhibited inward rectified K+ channels in a dosage dependent manner, and exhibited bigger effects upon Kir2.1 vs Kir2.3 in transfected HEK293 cells. As low as micromolar range concentrations of puerarin significantly inhibited Kv7.1 and IKs. These inhibitory effects may due to the direct inhibition of puerarin upon channels not via the PKA-dependent pathway. These results provided direct preclinical evidence that puerarin prolonged APD via its inhibitory effect upon Kv7.1 and IKs, contributing to a better understanding the mechanism of puerarin cardioprotection in the treatment of cardiovascular diseases.

Abstract
The phytoestrogen puerarin has been shown to protect neurons and astrocytes in the brain, and is therefore an attractive drug in the treatment of Alzheimer's disease, Parkinson's disease and cerebral ischemia. Whether puerarin exhibits the same biological processes in neurons and astrocytes in vitro has rarely been reported. In this study, cortical neurons and astrocytes of newborn Sprague-Dawley rats were separated, identified and co-cultured in a system based on Transwell membranes. The retention time and distribution of puerarin in each cell type was detected by fluorescence spectrophotometry and fluorescence microscope. The concentration of puerarin in both co-cultured and separately cultured neurons was greater than that of astrocytes. Puerarin concentration reached a maximum 20 minutes after it was added. At 60 minutes after its addition, a scant amount of drug was detected in astrocytes; however in both separately cultured and co-cultured neurons, the concentration of puerarin achieved a stable level of about 12.8 ng/mL. The results indicate that puerarin had a higher concentration and longer retention time in neurons than that observed in astrocytes.

Abstract
Puerarin is an active component of Pueraria lobata, which is a commonly used Chinese herbal medicine for the treatment of osteoporosis. The present study aimed to evaluate the osteoprotective effect of puerarin on glucocorticoid (GC)-induced apoptosis of osteoblasts in vitro. The effects of puerarin on dexamethasone (DEX)-induced cell apoptosis were assessed using enzyme-linked immunosorbent assay and a terminal deoxynucleotidyl transferase dUTP nick-end labeling assay, and found that the viability of hFOB1.19 cells was significantly increased following exposure to between 10−6 and 10−10 M puerarin, with a maximal anti-apoptotic effect at a concentration of 10−8 M. In addition, compared with the control group, puerarin upregulated the transcription and protein levels of B-cell lymphoma-2 and downregulated B-cell-associated X protein in the hFOB1.19 cells. Puerarin attenuated the DEX-induced release of cytochrome c and cleavage of caspase-3, and treatment with puerarin inhibited the c-Jun N-terminal kinase (JNK) pathway and activated the phosphoinositide 3-kinase (PI3K)/Akt pathway in the hFOB1.19 cells. Furthermore, the Akt inhibitor, LY294002, partly eliminated the protective effect of puerarin on DEX-induced apoptosis, and puerarin combined with the JNK inhibitor, SP600125, suppressed DEX-induced apoptosis to a lesser extent than in the cells treated with SP600125 alone. These results suggested that the JNK and PI3K/Akt signaling pathways mediate the inhibitory effects of puerarin on apoptosis in the hFOB1.19 cells. In conclusion, puerarin prevented DEX-induced apoptosis of hFOB1.19 cells via inhibition of the JNK pathway and activation of the PI3K/Akt signaling pathway in the cells, dependent on the mitochondrial apoptotic pathway. These results support puerarin as a promising target in the treatment of GC-induced osteoporosis.

Abstract
Contemporary pharmacological research has demonstrated that puerarin, the most important phytoestrogen extracted from Pueraria lobata(Willd.) Ohwi, has protecting functions on the cardiovascular system, nervous system, osteoporosis, liver injury, and inflammation in vivo and in vitro. Most of these research studies focused on inhibiting oxidative stress and apoptosis through regulating various bioactivators and signal pathways. Among these, superoxide dismutase (SOD), endothelial nitric oxide synthase (eNOS) and malondialdehyde (MDA), and PI3K/Akt, MAPK, and NF-κB are of great importance. The data cited in this review were mainly obtained from articles listed in PubMed and Elsevier SDOL published from 1959 to 2013, and the search term used was "puerarin".

Abstract
Puerarin is an isoflavone isolated from traditional Chinese medicine Ge-gen (Radix Puerariae). Clinical studies have confirmed the cardioprotective effects of puerarin; however, the mechanisms underlying these effects are still unclear. On the basis of previous findings, we hypothesized that puerarin protects cardiomyocytes from ischemia-reperfusion injury via the protein kinase C epsilon (PKCε) (a critical cardioprotective protein) signalling pathway. Neonatal rat primary cardiomyocytes were preconditioned with puerarin or puerarin plus εV1-2, a selective PKCε inhibitor, prior to anoxia/reoxygenation (A/R) treatment. Western blot analysis showed that expression and activity of PKCε protein in puerarin preconditioned group were both increased compared with the control or A/R group. Subsequent assays showed that preconditioning with puerarin could increase the viability of neonatal rat primary cardiomyocytes treated with A/R, decreased the generation of reactive oxygen species (ROS), loss of mitochondrial membrane potential, cell necrosis and apoptosis induced by A/R injury. However, the protective effects of puerarin completely disappeared in the group pretreated with puerarin plus εV1-2. Thus, for the first time, we revealed the protective effects of puerarin in cardiomocytes from anoxia/reoxygenation injury are mediated by PKCε.

Abstract
Puerarin is the major bioactive ingredient isolated from the root of the Pueraria lobata (Willd.) Ohwi, which is well known as Gegen (Chinese name) in traditional Chinese medicine. As the most abundant secondary metabolite, puerarin was isolated from Gegen in the late 1950s. Since then, its pharmacological properties have been extensively investigated. It is available in common foods and is used in alternative medicine. It has been widely used in the treatment of cardiovascular and cerebrovascular diseases, diabetes and diabetic complications, osteonecrosis, Parkinson's disease, Alzheimer's disease, endometriosis, and cancer. The beneficial effects of puerarin on the various medicinal purposes may be due to its wide spectrum of pharmacological properties such as vasodilation, cardioprotection, neuroprotection, antioxidant, anticancer, antiinflammation, alleviating pain, promoting bone formation, inhibiting alcohol intake, and attenuating insulin resistance. However, the direct molecular mechanisms and targets remain unclear. This review provides a comprehensive summary of the pharmacological effects of puerarin.

Abstract
BACKGROUND Puerarin (daidzein 8-C-glucoside) has potential on preventing osteoporosis. This study aims to investigate the effects of puerarin on osteogenesis and adipogenesis in vitro. METHODS CCK-8 assay, alkaline phosphatase (ALP) activity and Alizarin Red S were used to measure the effects of puerarin on proliferation, osteoblastic differentiation, and mineralization in osteoblast-like MC3T3-E1 cells. The effects of puerarin on adipogenesis were measured by Oil Red O staining and intracellular triglyceride level in preadipocyte 3T3-L1 cells. The mRNA and protein levels of osteogenesis- and adiopogenesis-related factors were detected by qRT-PCR and western blot, respectively. Further, the secreted osteocalcin levels and nuclear translocation of β-catenin were detected by ELISA and immunofluorescence assay, respectively. RESULTS As to osteogenesis, puerarin could stimulate proliferation (1 μM, P = 0.012; 10 μM, P = 0.015; 20 μM, P = 0.050), ALP activity (20 μM, P = 0.008) and calcium nodule formation (20 μM, P = 0.011) in a dose-dependent manner. Puerarin (20 μM) promoted osteocalcin secretion (P = 0.004) and the protein expression of both osteopontin (P = 0.001) and osteoprotegerin (P = 0.003). As to adipogenesis, puerarin suppressed adipocytes formation and intracellular triglyceride level (P = 0.001). In addition, puerarin (20 μM) decreased the mRNA and protein levels of CCAAT/enhancer binding protein α (P = 0.001, P = 0.002), proliferator-activated receptor γ (P = 0.005, P = 0.003), and adipocyte lipid-binding protein 4 (P = 0.001, P = 0.001). Moreover, phosphorylation of AKT1-Ser437 (10 μM, P = 0.003; 20 μM, P = 0.007) and GSK-Ser9 (10 μM, P = 0.005; 20 μM, P = 0.003), and the nuclear translocation of β-catenin (10 μM, P = 0.006; 10 μM, P = 0.002) were increased in 3T3-L1 cells treated by puerarin. CONCLUSION Puerarin promoted osteogenesis and inhibited adipogenesis in vivo, and Akt/GSK-3β/β-catenin signaling pathway was involved in the suppression of adipogenesis.

Abstract
This systematic review aims to evaluate current evidence for the benefit and side effect of oral Panax notoginseng preparation for coronary heart disease (CHD). We included 17 randomized clinical trials (17 papers and 1747 participants). Comparing with no intervention on the basis of conventional therapy, oral Panax notoginseng did not show significant effect on reducing cardiovascular events, but it could alleviate angina pectoris (including improving the symptoms of angina pectoris [RR 1.20; 95% CI 1.12 to 1.28; 7 trials, n = 791], improving electrocardiogram [RR 1.35; 95% CI 1.19 to 1.53; 8 trials, n = 727], decreasing the recurrence of angina pectoris [RR 0.38; 95% CI 0.16 to 0.94; 1 trials, n = 60], duration of angina pectoris [RR -1.88; 95% CI -2.08 to -1.69; 2 trials, n = 292], and dosage of nitroglycerin [MD -1.13; 95% CI -1.70 to -0.56; 2 trials, n = 212]); oral Panax notoginseng had no significant difference compared with isosorbide dinitrate on immediate effect for angina pectoris [RR 0.96; 95% CI 0.81 to 1.15; 1 trial, n = 80]. In conclusion, oral Panax notoginseng preparation could relieve angina pectoris related symptoms. However, the small sample size and potential bias of most trials influence the convincingness of this conclusion. More rigorous trials with high quality are needed to give high level of evidence, especially for the potential benefit of cardiovascular events.

Abstract
Objective. The aim of this overview was to summarize the outcome measures of Chinese herbal medicine (CHM) as the treatment of coronary heart disease (CHD) based on available systematic reviews (SRs), so as to display the current situation and evaluate the potential benefits and advantages of CHM on CHD. Methods. An extensive search included the Cochrane Database of Systematic Reviews, MEDLINE, and 4 databases in Chinese. SRs of CHM for CHD were included. Besides evaluating and summarizing the outcome measures, we also estimated the quality of the included reviews by PRISMA (preferred reporting items for systematic reviews and meta-analyses). Data were extracted according to predefined inclusion criteria by two independent reviewers. Results. 46 articles were included. 20 kinds of CHM were reviewed. 7 SRs were concerned with myocardial infarction (MI), 38 SRs were related to angina pectoris. 11 SRs had primary endpoints, while others focused on secondary endpoints to evaluate CHM for CHD such as angina pectoris and electrocardiogram (ECG). One SR reported more adverse effects of CHM for CHD and of the SRs analyzed quality of life. Many CHM appeared to have significant effect on improving symptoms, ECG, biomarkers and so on. However, most SRs failed to make a definite conclusion for the effectiveness of CHM in CHD patients due specifically to the poor evidence. And according to PRISMA we found most of the trials in the SRs were of low quality. Conclusion. Primary endpoints were not used widely. The benefits of CHM for CHD need to be confirmed in the future with RCTs of more persuasive primary endpoints and high-quality SRs.

Abstract
Objective. The aim of this overview was to evaluate and summarize Cochrane reviews of traditional Chinese herbal products (TCHPs) as the treatment for coronary heart disease (CHD). Methods. We searched the Cochrane Database that was concerned with the effectiveness of TCHPs for CHD. We also searched the Cochrane Central Register of Controlled Trials. Reviews and primary studies of TCHP as the treatment of any type of CHD were included. Data were extracted according to predefined inclusion criteria by two independent reviewers. Results. Six Cochrane reviews were included. They related to a wide range of TCHPs for different types of CHD. Four reviews were concerned with angina pectoris (unstable or stable), one review was concerned with heart failure, and for acute myocardial infarction. No reviews concluded that TCHPs were definitely effective for CHD because of the weak evidence. Eight primary studies were TCHPs from CHD. These studies also maybe result in bias, but better than before. Conclusion. Several Cochrane reviews of TCHPs for the treatment of different types of CHD have recently been published. None of these reviews got definite conclusion favoring the effectiveness of TCHPs due to the weak evidence. With the improved quality of the new registered RCTs. The potential role of TCHPs in treating CHD is anticipated to be detected.

Abstract
AIM OF THE STUDY The purpose of this study was to explore the optimal therapeutic timing and mechanism of puerarin treatment of spinal cord ischemia-reperfusion injury. MATERIALS AND METHODS The spinal ischemia-reperfusion injury was conducted in male Sprague-Dawley rats, and 50mg/kg of puerarin was injected intraperitoneally at 1, 2, 4 and 6h after the injury. Motor function was measured 48 h after reperfusion started. Thioredoxin expression and apoptosis indices were determined. RESULTS Improvement of motor function at 1, 2, and 4h was demonstrated in the animals with puerarin treatment. Ischemia-reperfusion injury resulted in a decrease in the expression of thioredoxin, while puerarin administration elevated the expression of thioredoxin-1/thioredoxin-2 mRNA. Apoptosis indices were significantly reduced by puerarin administration. CONCLUSIONS We conclude that administration of puerarin within 4h of spinal ischemia-reperfusion injury reduces ischemic reperfusion damage, and that the neuroprotective effect of puerarin involves an increase in the transcription of thioredoxin and a reduction of apoptosis.

Abstract
BACKGROUND The Cochrane Collaboration, an international not-for-profit organization that prepares and maintains systematic reviews of randomized trials of health care therapies, has produced reviews summarizing much of the evidence on Traditional Chinese Medicine (TCM). Our objective was to review the evidence base according to Cochrane systematic reviews. METHODS In order to detect reviews focusing on TCM, we searched the titles and abstracts of all reviews in Issue 4, 2008 of the Cochrane Database of Systematic Reviews. For each review, we extracted data on the number of trials included and the total number of participants. We provided an indication of the strength of the review findings by assessing the reviewers' abstract conclusions statement. We supplemented our assessment of the abstract conclusions statements with a listing of the comparisons and outcomes showing statistically significant meta-analyses results. RESULTS We identified 70 Cochrane systematic reviews of TCM, primarily acupuncture (n = 26) and Chinese herbal medicine (n = 42), and 1 each of moxibustion and t'ai chi. Nineteen (19) of 26 acupuncture reviews and 22/42 herbal medicine reviews concluded that there was not enough good quality trial evidence to make any conclusion about the efficacy of the evaluated treatment, while the remaining 7 acupuncture and 20 herbal medicine reviews and each of the moxibustion and t'ai chi reviews indicated a suggestion of benefit, which was qualified by a caveat about the poor quality and quantity of studies. Most reviews included many distinct interventions, controls, outcomes, and populations, and a large number of different comparisons were made, each with a distinct forest plot. CONCLUSIONS Most Cochrane systematic reviews of TCM are inconclusive, due specifically to the poor methodology and heterogeneity of the studies reviewed. Some systematic reviews provide preliminary evidence of Chinese medicine's benefits to certain patient populations, underscoring the importance and appropriateness of further research. These preliminary findings should be considered tentative and need to be confirmed with rigorous randomized controlled trials.
