ABSTRACT

Traditional Chinese medicine(TCM) syndrome-based efficacy is an evaluation index which is unique to TCM and can reflect the advantages of TCM. The development of the methods and measurement tools for evaluating TCM syndrome-based efficacy can provide objective and quantitative evidence for the clinical efficacy evaluation of TCM and the development of new Chinese medicine preparations, being the exploration direction of innovative methods and technologies for evaluating TCM efficacy. The conventional evaluation methods are subjective and limited to the mitigation of symptoms and the improvement of physical signs, which make it difficult to form a unified evaluation standard. In addition, the evaluation methods lack unity, objectivity, and quantitative research. The scientific connotation, evaluation ideas and methods, and key technologies of the evaluation for the therapeutic effect on syndromes remain unclear, which leads to diverse evaluation modes, methods, and indexes. The syndrome-based efficacy scale provides a new idea for the objective quantification and standardization of TCM syndromes. This review systematically summarizes the methods and problems, introduces the research progress in the evaluation scales, and puts forward some thoughts on the characteristics of TCM syndrome-based efficacy evaluation, aiming to provide insights for the research in this field.

ABSTRACT

BACKGROUND: Percutaneous coronary intervention (PCI), the most common method in treating coronary artery disease (CAD), has a variety of side effects. Yiqi Huoxue therapy (YQHX) can effectively alleviate the symptoms of patients and reduce the side effects. However, a reliable and systematic assessment of the methodologies is not available. METHODS: Seven electronic databases were searched to identify randomized controlled trials of YQHX method for CAD after PCI. The quality assessment of the trials included was performed by employing the Cochrane Risk of Bias tool. RESULTS: One thousand eight hundred sixty-eight patients from 23 randomized controlled trials were included in this review. The aggregated results showed that the experimental group got better effect in increasing ORR, TCMSRR, ECG, HDL-C, and in lowering the level of CRP, TC, and MACE in comparison with the control group. CONCLUSION: YQHX method is a valid complementary and alternative therapy in the management of CAD after PCI, and is an effective and safe therapy for CAD.

ABSTRACT

BACKGROUND: Chronic heart failure (CHF) is the final destination of most cardiovascular diseases and the most important cause of death. The main clinical manifestations were pulmonary congestion and decreased cardiac output. The purpose of this systematic review is to evaluate the effectiveness of Yiqi Huoxue therapy on CHF. METHODS: Seven electronic databases were searched to identify randomized controlled trials of Yiqi Huoxue (YQHX) method for CHF until April 30, 2020. The quality assessment of the included trials was performed by employing the Cochrane Risk of Bias tool and Jadad scale. RESULTS: Nineteen randomized controlled trials were included in our review. Most of the included trials were considered as low quality. The aggregated results suggested that experimental group with YQHX therapy got better effect in increasing overall response rate (risk ratio, RR = 1.21, 95% confidence interval, CI 1.15-1.27), traditional Chinese medicine (TCM) syndrome response rate (RR = 1.26, 95% CI 1.17-1.36), 6-minute walk test (RR = 2.14, 95% CI 1.05-3.22), left ventricular ejection fraction (RR = 0.97, 95% CI 0.60-1.34), and stroke volume (standardized mean difference, SMD = 0.94, 95% CI 0.23-1.56), and in lowering down the TCM syndrome scores (SMD = -0.78, 95% CI -0.91 to -0.64), Minnesota Living with Heart Failure questionnaire (SMD = -1.01, 95% CI -1.56 to -0.45), 6-month readmission rate (RR = 0.50, 95% CI 0.28-0.89), B-type natriuretic peptide (SMD = -0.89, 95% CI -1.52 to -0.25), NT-proBNP (SMD = -2.07, 95% CI -3.34 to -0.08), and C-reactive protein (SMD = -2.04, 95% CI -4.12 to -0.67) as compared to using conventional Western medicine alone. There were no significant differences found in left ventricular end diastolic diameter and E/E' between experimental groups and control groups. Moreover, the included sample capacity is small and the trails are all in Chinese. Quality of the evidence for outcomes were "low" and "very low" according to the GRADE assessment. CONCLUSION: YQHX is a valid complementary and alternative therapy in the management of CHF, especially in improving overall response rate, TCM syndrome response rate, 6-minute walk test, left ventricular ejection fraction, and stroke volume and in decreasing TCM syndrome scores, Minnesota Living with Heart Failure questionnaire, 6-month readmission rate, B-type natriuretic peptide, NT-proBNP, and C-reactive protein levels. Hence, YQHX is a relatively effective and safe therapy for CHF patients, which can be popularized and applied in the clinic. More long-term follow-up studies are still needed to substantiate and confirm the current findings.

ABSTRACT

In recent years, the real-world studies (RWS) have attracted extensive attention, and the real-world evidence (RWE) has been accepted to support the drug development in China and abroad. However, there is still a lack of standards for the evaluation of the quality of RWE. It is necessary to formulate a quality evaluation and reporting specification for RWE especially in traditional Chinese medicine (TCM). To this end, under the guidance of China Association of Chinese Medicine, the Quality Evaluation and Reporting Specification for Real-World Evidence of Traditional Chinese Medicine (QUERST) Group, including 24 experts (clinical epidemiologists, clinicians, pharmacologists, ethical reviewer and statisticians), was established to develop the specification. This specification contains the listing of classification of RWS design and RWE, the general principles and methods of RWE quality evaluation (26 tools or scales), 25 types of bias in RWS, the special considerations in evaluating the quality of RWE of TCM, and the 19 reporting standards of RWE. This specification aims to propose the quality evaluation principles and key points of RWE, and provide guidance for the proper use of RWE in the development of TCM new drugs.

ABSTRACT

OBJECTIVE: To investigate the effect and safety of Guanxinning Tablet (, GXN) for the treatment of stable angina pectoris patients with Xin (Heart)-blood stagnation syndrome (XBSS). METHODS: One hundred and sixty stable angina pectoris patients with XBSS were randomly assigned to receive GXN (80 cases) or placebo (80 cases, Guanxinning simulation tablets, mainly composed of lactose), 4 tablets (0.38 g/tablet), thrice daily for 12 weeks. After treatment, an exercise stress test (treadmill protocol), Chinese medicine (CM) syndrome score, electrocardiogram (ECG), and nitroglycerin withdrawal rate were evaluated and compared in the patients between the two groups. Meanwhile, adverse events (AEs) were evaluated during the whole clinical trial. RESULTS: Compared with the control group, the time extension of exercise duration in the GXN group increased 29.28 ±17.67 s after treatment (P>0.05); moreover, the change of exercise duration in the GXN group increased 63.10 ±96.96 s in subgroup analysis (P<0.05). The effective rates of angina pectoris, CM syndrome and ECG as well as nitroglycerin withdrawal rate were 81.33%, 90.67%, 45.76%, and 70.73%, respectively in the GXN group, which were all significantly higher than those in the control group (40.58%, 75.36%, 26.92%, 28.21%, respectively, P<0.05). CONCLUSION: GXN was a safe and effective treatment for stable angina pectoris patients with XBSS at a dose of 4 tablets, thrice daily.

ABSTRACT

BACKGROUND: Alstonia scholaris (Apocynaceae) was reported to be a rich source of indole alkaloids, which exhibited remarkably bioactivities. The leaf of A. scholaris has been used in 'dai' ethno-medicine for treatment of respiratory diseases, and the defined indole alkaloids from leaf of A. scholaris has been registered as investigational new botanical drug (No. 2011L01436) and was approved for phase I/II clinical trials by China Food and Drug Administration (CFDA). PURPOSE: The aim of the trial is to evaluate the safety and explore the relationship of dosing frequency and pharmacokinetics after oral administration of capsule of alkaloids from leaf of A. scholaris (CALAS) at different doses. METHODS: In this randomized, open-labelled, single-center clinical trial, the safety and pharmacokinetics of CALAS were assessed in eligible healthy Chinese volunteers after oral administration of different doses. Each volunteer (n = 10 per group) received single dose of CALAS from 20 mg, 40 mg, 80 mg to 120 mg orally. The pharmacokinetics of CALAS was investigated in healthy Chinese subjects' plasma by a fully-validated LC-MS/MS method. Safety was assessed biochemically and clinically throughout the study, and drug re-excitation research was conducted to verify the correlation between investigational product and minor adverse events. The trial was registered on August 26, 2015 (http://www.chictr.org.cn/showproj.aspx?proj=11736), number ChiCTR-IPR-15006976. RESULTS: 40 subjects completed the study, and as a result, vallesamine had the highest concentration in plasma of healthy volunteers, and the AUC exposure level in each compounds in turn is vallesamine > scholaricine > 19-epischolaricine > picrinine. For the safety evaluation of CALAS, two cases of minor adverse events were observed during the trial, but the drug re-excitation research indicated that these two adverse events were related to the individual's physiological variation. CONCLUSION: Pharmacokinetic characteristics of each ingredient showed different patterns. 19-epischolaricine, vallesamine and picrinine were match to the linear pharmacokinetic characteristics, but scholaricine conformed to the characteristics of nonlinear pharmacokinetics. The CALAS was safe in healthy subjects under the current dose regimen.

ABSTRACT

Iron homeostasis is strictly regulated in mammals, and disordered iron metabolism is recognized as a risk factor for various diseases, including cardiovascular disease. The hepcidin­ferroportin axis is the key signaling mechanism that controls systemic iron homeostasis. Increased serum hepcidin is associated with multiple types of cancer and atherosclerosis (AS), and therapeutics that decrease hepcidin levels have been proposed to treat these diseases. However, the effects of abnormal circulating hepcidin on hyperlipidemia remain unexploited. The natural compound tetramethylpyrazine (TMP) has been reported to have therapeutic effects on cardiovascular diseases, whereas the mechanisms involved remain incompletely understood. Thus, the effects of TMP on the expression of hepcidin in hyperlipidemic mice were investigated and the mechanisms involved were explored. Hyperlipidemia increased serum hepcidin, which was inhibited by TMP intervention. The results also indicated that TMP may decrease hepcidin expression via inhibition of Stat3 signaling. These findings suggest a promising rationale to prevent and hyperlidemia by targeting hepcidin or its upstream regulators, and highlight the potential application of natural compounds in treating hepcidin disorder­associated diseases.

ABSTRACT

BACKGROUND/AIMS: Systemic iron homeostasis is strictly governed in mammals; however, disordered iron metabolism (such as excess iron burden) is recognized as a risk factor for various types of diseases including AS (Atherosclerosis). The hepcidin-ferroportin axis plays the key role in regulation of iron homeostasis and modulation of this signaling could be a potential therapeutic strategy in the treatment of these diseases. TMP (Tetramethylpyrazine) has been reported to have therapeutical effect on AS. Here, we aimed to investigate the effect of iron overload under hyperlipidemia condition on the endothelial injury, inflammation and oxidative stress by employing FPN1 Tek-cre mouse model with or without TMP intervention. METHODS: Subjects for this study were 80 FPN1 Tek-cre mice and 40 C57BL/6 mice and we randomly divided them into six groups: Group N: C57BL/6 mice with normal diet, Group M: C57BL/6 mice with high-fat diet, Group FN: FPN1 Tek-cre mice with normal diet, Group FNT: FPN1 Tek-cre mice with normal diet and TMP injection, Group FM: FPN1 Tek-cre mice with high-fat diet, Group FMT: FPN1 Tek-cre mice with high-fat diet and TMP injection. After seven days of treatment, blood samples were obtained to detect the levels of blood lipids, Hepcidin, NO, ET-1, ROS, MDA, SOD, IL-1, IL-6 and TNF-α respectively. The liver and aorta were used for testing the lipid deposition by using hematoxylin and eosin(HE). RESULTS: Hyperlipidemia could cause iron overload in the aorta and increased serum hepcidin level, particularly in FPN1 Tek-cre mice, and can be reversed by TMP intervention. Knockout of Fpn1 induced increase of serum hepcidin, exacerbated endothelial dysfunction, oxidative stress and inflammatory response, particularly under hyperlipidemia condition. TMP intervention attenuated these processes. CONCLUSIONS: Our study signifies the potential application of certain natural compounds to ameliorating iron disorders induced by hyperlipidemia and protecting on endothelial function through modulation of hepcidin-ferroportin signaling.

ABSTRACT

Strawberry fruits (cv. Benihoppe, Tochiotome, Sachinoka, and Guimeiren) were harvested and evaluated the flavor and nutritional parameters. By principal component analysis and hierarchical clustering analysis, differences were observed based on the volatile compounds composition, sugar and acid concentration, sweetness, and total soluble sugars/total organic acids of the four varieties. A total of 37, 48, 65, and 74 volatile compounds were identified and determined in cv. Benihoppe, Tochiotome, Sachinoka, and Guimeiren strawberry fruits extracted by head-space solid-phase microextraction (HS-SPME), respectively. Esters significantly dominated the chemical composition of the four varieties. Furaneol was detected in cultivars of Sachinoka and Guimeiren, but mesifuran was only found in cv. Tochiotome. Tochiotome and Sachinoka showed higher content of linalool and (E)-nerolidol. Sachinoka showed the highest content of total sugars and total acids. Guimeiren showed higher sweetness index than the other three cultivars. Firmness of Tochiotome was highest among all the varieties. The highest total soluble solids TSS value was found in cv. Sachinoka, followed by the Guimeiren and Tochiotome varieties. Sachinoka had the highest titratable acidity TA value. The content of ascorbic acid (AsA) of cv. Tochiotome was higher than the others, but there was no significant difference in cultivars of Benihoppe, Tochiotome, and Sachinoka. Fructose and glucose were the major sugars in all cultivars. Citric acid was the major organic acid in cv. Tochiotome, cv. Sachinoka, and cv. Guimeiren. Tochiotome had higher ratios of TSS/TA and total sugars/total organic acids than others, arising from its lower acid content. The order of the comprehensive evaluation score was Sachinoka>Guimeiren>Tochiotome>Benihoppe.

ABSTRACT

Body fat storage before hibernation affects the timing of immergence in Daurian ground squirrels (Spermophilus dauricus). Leptin is an adipose signal and plays vital role in energy homeostasis mainly by action in brain. To test the hypothesis that leptin plays a role in facilitating the process of hibernation, squirrels were administrated with recombinant murine leptin (1µg/day) through intracerebroventricular (ICV) injection for 12 days during fattening. From day 7 to 12, animals were moved into a cold room (5±1°C) with constant darkness which functioned as hibernaculum. Energy intake, body mass and core body temperature (Tb) were continuously monitored throughout the course of experiment. Resting metabolic rate (RMR) was measured under both warm and cold conditions. At the end of leptin administration, we measured the serum concentration of hormones related to energy regulation, mRNA expression of hypothalamic neuropeptides and uncoupling protein 1 (UCP1) levels in brown adipose tissue (BAT). Our results showed that during leptin administration, the cumulative food intake and increase of body mass were suppressed while Tb and RMR were unaltered. The proportion of torpid squirrels was not different between two groups. At the end of leptin administration, the expressions of hypothalamic neuropeptide Y and agouti gene-related protein were suppressed. There were no differences in UCP1 mRNA expression or protein content in BAT between groups. Our data suggest that leptin can affect energy intake via hypothalamic neuropeptides, but is not involved in the initiation of hibernation in fattening Daurian ground squirrels.

ABSTRACT

Dormancy is a biological characteristic developed to resist the cold conditions in winter. The bZIP transcription factors are present exclusively in eukaryotes and have been identified and classified in many species. bZIP proteins are known to regulate numerous biological processes, however, the role of bZIP in bud dodormancy has not been studied extensively. In total, 50 PpbZIP transcription factor-encoding genes were identified and categorized them into 10 groups (A-I and S). Similar intron/exon structures, additional conserved motifs, and DNA-binding site specificity supported our classification scheme. Additionally, chromosomal distribution and collinearity analyses suggested that expansion of the PpbZIP transcription factor family was due to segment/chromosomal duplications. We also predicted the dimerization properties based on characteristic features of the leucine zipper and classified PpbZIP proteins into 23 subfamilies. Furthermore, qRT-PCR results indicated that PpbZIPs genes may be involved in regulating dormancy. The same gene of different species might participate in different regulating networks through interactions with specific partners. Our expression profiling results complemented the microarray data, suggesting that co-expression patterns of bZIP transcription factors during dormancy differed among deciduous fruit trees. Our findings further clarify the molecular characteristics of the PpbZIP transcription factor family, including potential gene functions during dormancy. This information may facilitate further research on the evolutionary history and biological functions of bZIP proteins in peach and other rosaceae plants.

ABSTRACT

Objective To observe the correlation between blood glucose fluctuation in type 2 dia- betes mellitus ( T2DM) patients and vascular endothelial injury/platelet activation/protein kinase Cß1 (PKCpß1). Methods Capillary blood was collected from finger tips of 38 T2DM patients at 7 time points, i.e., before 3 meals, 2 h after 3 meals, 21:00 pm before sleep. The mean amplitude of plasma glucose excursions (MAGE) was calculated. The peripheral blood platelet aggregation rate (PAG) induced by a- denosine diphosphate (ADP) and platelet membrane protein level of CD62p were determined by platelet fluorescent aggregometer and flow cytometry respectively. HbAlc was measured by ion-exchange high- performance liquid chromatography. Serum levels of E-selectin, von Willebrand factor ( vWF), and PKCß1 were detected by ELISA. Meanwhile, liver and renal functions, blood lipids were also measured. Their blood pressure was measured and body mass index (BMI) calculated. By taking HbA1c as a moni- tored index for assessing long-term glucose control, MAGE as an indicator for assessing glucose fluctua- tion, the correlations between serum markers for vascular endothelial injury (levels of E-selectin and vWF)/platelet activation indices (PAG and CD62p expression) and PKCß1 level/MAGE respectively were analyzed using Pearson correlation analysis and multivariant Logistic regression. The correlations be- tween PKCß1 level and MAGE/HbA1 c were also analyzed. Results In simple correlation analysis, there were no significant correlations between age/BMI/course of disease/medical history/serum levels of E-se- lectin/vWF/PKCß1/PAG/CD62p expression and MAGE (P >0. 05). There were significant correlations be- tween vascular endothelial injury markers ( E-selectin and vWF)/platelet activation indicators ( PAG, CD62p expression) and MAGE (r =0. 468, 0. 609, 0. 451 , 0. 674; P <0. 01). There were significant corre- lations between PKCß1 and glucose assessment indicators (MAGE and HbA1c)/vascular endothelial inju- ry markers ( E-selectin and vWF) , platelet activation indicators ( PAG and CD62p expression) (r = 0. 643, 0. 705, 0. 394, 0. 665, 0. 441 , 0. 577; P <0. 01). Conclusion PKCß1 , the key regulatory gene of coronary artery disease with blood stasis syndrome, was closely related with the degree of vascular en- dothelial injury and aggregation level of platelet activation in T2DM patients with blood glucose fluctuation.

ABSTRACT

AIMS: Estrogen plays a protective role in atherosclerosis. Our preliminary work demonstrated that the active conformation of Tanshinone IIA(TanIIA) is similar to the 17ß-estradiol and it can bind to the estrogen receptor. Here, we hypothesized that Tanshinone IIA might have anti-inflammatory and anti-oxidative effects in atherosclerosis, mediated through estrogen receptor activation. METHODS: Subjects for this study were 120 apoE(-/-) female mice and 20 C57/BL female mice. The apoE(-/-) mice were ovariectomized (OVX) and the C57/BL mice were sham ovariectomized. The sham OVX mice were maintained on a normal diet (NOR) group. The OVX apoE(-/-) mice were fed a high fat diet and randomly divided into 6 groups: Model (MOD) group which was fed a high fat diet only, E2 group were given estrogen (E2) 0.13 mg/kg/d; E2+ICI group were given E2:0.13 mg/kg/d and ICI182780:65 mg/kg/m; TLD group (TanIIA low dose) were given TanIIA: 30 mg/kg/d; THD group (TanIIA high dose) were given TanIIA:60 mg/kg/d; and TLD+ICI group were given TanIIA 30 mg/kg/d and ICI182780 65 mg/kg/m. After three months of treatment, the aorta and the blood of the mice from each group was collected. The aorta were used for testing the lipid deposition by using hematoxylin and eosin(HE) and oil red O staining and for testing the expression of p-ERK1/2 by Western blot. The blood was used for testing the serum cholesterol, superoxide dismutase (SOD), methane dicarboxylic aldehyde (MDA), nuclear factor kappa (NF-κB), soluble intercellular cell adhesion molecule-1 (sICAM-1), activating protein-1 (AP-1), E-selectin and 17ß-estradiol in serum. RESULTS: Tanshinone IIA significantly reduced the lipid deposition in aorta, decreased the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), very low density lipoprotein (VLDL), MDA, NF-κB, sICAM-1, AP-1, and E-selectin in serum but increased the levels of high density lipoprotein (HDL) and SOD in serum. Tanshinone IIA also suppressed the expression of p-ERK1/2. Tanshinone IIA had no effect of level of serum 17ß-estradiol levels. All of the effects of Tanshinone IIA were similar to estrogen and were inhibited by the estrogen receptor antagonist ICI182780. CONCLUSION: Tanshinone IIA may play an anti-inflammatory and anti-oxidative stress role in OVX atherosclerotic apoE(-/-) mice by activating the estrogen receptor through the ERK signaling pathway. Therefore, Tanshinone IIA, as a phytoestrogen, could be used for estrogen replacement therapy for cardiovascular disease of postmenopausal women.

ABSTRACT

Ginsenoside Rb3 (GRb3) is one of the main components in plasma of Panax quinquefolius Saponin of stem and leaf (PQS), which can be into human plasma. Previous studies have found PQS has estrogen-like vascular protective effects. In the present study, we investigated the estrogen-like protective effect of GRb3 on oxidative stress and dysfunction of endothelial cells induced by oxidized low-density lipoprotein. The activities of SOD, NOS and the contents of MDA in the cell lysate were examined by enzyme method or spectrophotometry. The NO and ET-1 concentrations in the cell culture supernatant were measured by ELISA method. The iNOS and eNOS mRNA expression were measured by real time RT-PCR, while the phosphorylation levels of Akt was measured by Western blotting. The results showed that GRb3 could enhance the activity of SOD, reduce the content of MDA, increase the level of NOS, NO, ET-1 and iNOS mRNA expression while decrease the eNOS mRNA expression and the phosphorylation level of Akt. These effects were blocked by estrogen receptor antagonist ICI182780. GRb3 can play a role in protecting vascular endothelial cells by estrogen receptors, the protective mechanism is similar to 17-ß estrodiol.

ABSTRACT

The purpose of this study was to investigate clinical aspects and quality of life (QOL) as risk factors for depression in patients with epilepsy. One hundred and forty outpatients with a diagnosis of epilepsy who were attending our epilepsy center participated. Patients anonymously filled out a questionnaire with clinical data related to epilepsy. Depression level was evaluated by the Hamilton Depression Rating Scale-17 (HAMD-17), and quality of life was evaluated by the Quality of Life in Epilepsy-31 (QOLIE-31). Thirty-six patients with epilepsy suffered from depression (25.7%). Complex partial seizures (OR=0.112) and number of seizure types (OR=3.773) were found to be clinical risk factors for depression. Low scores for seizure worry (OR=0.947) and social function (OR=0.947) on the QOLIE-31 increased the probability of depression in patients with epilepsy.
