Roles of ß-catenin in innate immune process and regulating intestinal flora in Qi river crucian carp (Carassius auratus).

In mammals, ß-catenin participates in innate immune process through interaction with NF-κB signaling pathway. However, its role in teleost immune processes remains largely unknown. We aimed to clarify the function of ß-catenin in the natural defense mechanism of Qi river crucian carp (Carassius auratus). ß-catenin exhibited a ubiquitous expression pattern in adult fish, as indicated by real-time PCR analysis. Following lipopolysaccharide (LPS), Polyinosinic-polycytidylic acid (polyI: C) and Aeromonas hydrophila (A. hydrophila) challenges, ß-catenin increased in gill, intestine, liver and kidney, indicating that ß-catenin likely plays a pivotal role in the immune response against pathogen infiltration. Inhibition of the ß-catenin pathway using FH535, an inhibitor of Wnt/ß-catenin pathway, resulting in pathological damage of the gill, intestine, liver and kidney, significant decrease of innate immune factors (C3, defb3, LYZ-C, INF-γ), upregulation of inflammatory factors (NF-κB, TNF-α, IL-1, IL-8), and downregulation of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) activities, increase of Malondialdehyde (MDA) content. Following A. hydrophila invasion, the mortality rate in the FH535 treatment group exceeded that of the control group. In addition, the diversity of intestinal microflora decreased and the community structure was uneven after FH535 treatment. In summary, our findings strongly suggest that ß-catenin plays a vital role in combating pathogen invasion and regulating intestinal flora in Qi river crucian carp.

Powering the future: Exploring self-charging cardiac implantable electronic devices and the Qi revolution.

The incidence and prevalence of cardiovascular diseases (CVD) have risen over the last few decades worldwide, resulting in a cost burden to healthcare systems and increasingly complex procedures. Among many strategies for treating heart diseases, treating arrhythmias using cardiac implantable electronic devices (CIEDs) has been shown to improve quality of life and reduce the incidence of sudden cardiac death. The battery-powered CIEDs have the inherent challenge of regular battery replacements depending upon energy usage for their programmed tasks. Nanogenerator-based  energy harvesters have been extensively studied, developed, and optimized continuously in recent years to overcome this challenge owing to their merits of self-powering abilities and good biocompatibility. Although these nanogenerators and others currently used in energy harvesters, such as biofuel cells (BFCs) exhibit an infinite spectrum of uses for this novel technology, their demerits should not be dismissed. Despite the emergence of Qi wireless power transfer (WPT) has revolutionized the technological world, its application in CIEDs has yet to be studied well. This review outlines the working principles and applications of currently employed energy harvesters to provide a preliminary exploration of CIEDs based on Qi WPT, which may be a promising technology for the next generation of functionalized CIEDs.

Clinical Value of Heart Qi in the Treatment of Chronic Heart Failure With Depression.

Context: Chronic heart failure (CHF) is a form of persistent heart failure. If a patient develops depression, it can worsen the severity of heart failure and can lead to adverse outcomes. No researchers have studied the effects of tonic heart qi soup for patients with CHF and depression. Objective: The study intended to evaluate the clinical efficacy of tonic heart qi soup in the treatment of chronic heart failure (CHF) for patients with comorbid depression. Design: The research team performed a prospective randomized controlled trial. Setting: The study took place in the Department of Chinese Medicine at Cangzhou Central Hospital in Cangzhou, Hebei Province, China. Participants: Participants were 120 patients with CHF at the hospital as inpatients or outpatients between January 2016 and January 2019. Intervention: The research team divided participants into two groups, with 60 patients each: (1) an intervention group, which received conventional Western medical treatment combined with treatment with a commercial tonic heart qi soup and (2) a control group, which received conventional Western medical treatment only. Outcome Measures: The research team measured: (1) treatment efficacy, (2) cardiac function, (3) adverse reactions, (4) B-type natriuretic peptide (BNP) and Ghrelin, and (5) depression. Results: In the intervention group, 55 participants showed significant improvement in the degree of heart failure, for a total effectiveness rate of 91.67%, which was significantly higher than that of the control group (P = .000). The intervention group had 10 participants in class II, 18 in class III, and 22 in class IV. Among them, 28 participants improved, indicating significantly better outcomes than those of the control group. The intervention group's BNP levels, at 1031.58 ± 118.83 pg/ml, and ghrelin levels, at 481.46 ± 57.53%, were significantly lower than those of the control group. No liver- or renal-function damage, insomnia, or significant adverse reactions occurred for either group. The intervention group's total incidence rate for adverse reactions, at 1.67%, was significantly lower than that of the control group, at 11.67% (P = .000) and also had a higher total effective rate in reducing depression, at 86.67%, compared to that of the control group, at 43.33%. Conclusions: Heart Qi Tonic Tang, as an adjunctive therapy, significantly improved outcomes for CHF patients with depression. It effectively reduced heart failure symptoms, with minimal adverse reactions and increased patient comfort and compliance.

Qi-Long-Tian capsule alleviates pulmonary fibrosis development by modulating inflammatory response and gut microbiota.

Pulmonary fibrosis (PF) is a chronic, progressive, and fibrotic interstitial lung disease with a high mortality rate. Qi-Long-Tian (QLT) capsule is an herbal formula with great potential for antifibrotic effects, consisting of San Qi (Notoginseng Radix et Rhizoma), Di Long [Pheretima aspergillum (E. Perrier)], and Hong Jingtian (Rhodiolae Crenulatae Radix et Rhizoma), and has been used in clinical practice for many years. To explore the relationship between the effects of Qi-Long-Tian capsule and gut microbiota of PF mice, pulmonary fibrosis model were established by tracheal drip injection of bleomycin. Thirty-six mice were randomly divided into 6 groups: control group (control), model group (model), QLT capsule low dose group (QL), QLT capsule medium dose group (QM), QLT capsule high dose group (QH), and pirfenidone group (PFD). After 21 days of treatment, after pulmonary function tests, the lung tissues, serums, and enterobacterial samples were collected for further analysis. HE staining and Masson's staining were used to detect changes as the main indicators of PF in each group, and the expression of hydroxyproline (HYP) related to collagen metabolism was detected by and alkaline hydrolysis method. qRT-PCR and ELISA were used to detect the mRNA and protein expressions of pro-inflammatory factors include interleukin 1ß (IL-1ß), interleukin 6 (IL-6), transforming growth factor ß1 (TGF-ß1), tumor necrosis factor α (TNF-α) in lung tissues and serums, and the inflammation-mediating factors include tight junction protein (ZO-1, Claudin, Occludin). ELISA was used to detect the protein expressions of secretory immunoglobulin A (sIgA), short-chain fatty acids (SCFAs), and lipopolysaccharide (LPS) in colonic tissues. 16sRNA gene sequencing was used to detect changes in the abundance and diversity of intestinal flora in the control, model, and QM groups, to search for differential genera, and analyze the correlation with inflammatory factors. QLT capsule effectively improved the status of pulmonary fibrosis and reduced HYP. In addition, QLT capsule significantly reduced the abnormal levels of pro-inflammatory factors, including IL-1ß, IL-6, TNF-α, and TGF-ß in lung tissue and serum, while improving the levels of pro-inflammatory related factors ZO-1, Claudin, Occludin, sIgA, SCFAs, and reducing LPS in the colon. The comparison between the alpha diversity and beta diversity in enterobacteria suggested that the composition of the gut flora in the control, model, and QLT capsule groups were different. QLT capsule significantly increased the relative abundance of Bacteroidia (which might limit the onset of inflammation) and decreased the relative abundance of Clostridia (which might promote inflammation). In addition, these two enterobacteria were closely associated with pro-inflammatory-related indicators and pro-inflammatory factors in PF. All these results suggest that QLT capsule intervenes in pulmonary fibrosis by regulating the differential genera of intestinal flora, increasing immunoglobulin secretion, repairing the intestinal mucosal barrier, reducing LPS entry into the blood, and decreasing inflammatory factor secretion in the serum, which in turn alleviates pulmonary inflammation. This study clarifies the therapeutic mechanism of QLT capsule in PF and provides a theoretical basis for it. It provides a theoretical basis for its further clinical application.

Effects of ginseng on short-chain fatty acids and intestinal microbiota in rats with spleen-qi deficiency based on gas chromatography-mass spectrometry and 16s rRNA technology.

RATIONALE: Spleen-qi deficiency syndrome, a common weakness syndrome in traditional Chinese medicine, results from insufficient spleen-qi levels. For centuries, ginseng has been relied upon as a traditional Chinese medicine to treat spleen-qi deficiency syndrome. Until now, the mechanism feature of ginseng in treating temper deficiency through intestinal bacteria and short-chain fatty acid (SCFA) metabolites has not been fully elucidated. METHODS: This study established a rat model of spleen-qi deficiency via multi-factor compound modeling that involved fatigue injury and a controlled diet. The content of SCFAs between different treatment groups was determined by gas chromatography-mass spectrometry. And the 16s rRNA sequencing technology was applied to reveal the effects of ginseng on the intestinal microecological environment of the rats. RESULTS: It was found that the ginseng treatment group exhibited the most remarkable regulatory effect on propionic acid, surpassing all other administration groups. Ginseng increased the relative abundance of beneficial bacteria and decreased that of harmful bacteria at the genus level in rats with spleen-qi deficiency syndrome. And propionic acid is significantly positively correlated with Lactobacillus level and significantly negatively correlated with uncultured_bacterium_f_Muribaculaceae (p < 0.05). n-Butyric acid is negatively correlated with the Faecalibaculum level (p < 0.01). n-Valeric acid is significantly negatively correlated with the Romboutsia level (p < 0.01). CONCLUSION: The mechanism of ginseng treatment for spleen-qi deficiency is elucidated from the perspective of gut microbiota and its metabolite SCFAs. It provides a new way for further development and utilization of ginseng and a theoretical basis.

Urine and serum metabolomics study of wild ginseng in rats with spleen-qi deficiency using rapid resolution liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry.

Patients with a spleen-qi deficiency often exhibit dysfunction in the metabolic system. Metabolites are considered the most direct reflection of individual physiological and pathological conditions and represent attractive candidates to provide deep insights into disease phenotypes. This study examines the potential therapeutic mechanism of wild ginseng on spleen-qi deficiency through the analysis of serum and urine metabolomics using rapid-resolution liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry. The reasons for the superiority of wild ginseng treatment over cultivated ginseng were also analyzed in depth. After wild ginseng intervention, anandamide, urobilinogen, aldosterone, and testosterone glucuronide were significantly reduced in serum. Meanwhile, argininosuccinic acid, L-cysteine, and seven other metabolites were significantly elevated in serum. Nine metabolites, including L-acetylcarnitine, and citrulline were elevated in the urine, and trimethylamine N-oxide, adrenic acid, and 10 other metabolites were reduced. Arginine biosynthesis, pantothenate and CoA biosynthesis, thiamin metabolism, taurine, and tryptophan metabolism pathways were mainly improved. Further analysis was conducted on the relationship between Lactobacillus and Akkermansia bacteria with metabolites, and it was found that they are mainly related to amino acid metabolites. This study provides strong theoretical support and direction for further explanation of the immune mechanism of wild ginseng and lays the foundation for future studies.

Combining lipidomics and efficacy-oriented compatibility revealed that Qi Ge decoction compatibility improved lipid metabolism in hyperlipidemic rats.

The mechanism underlying traditional Chinese medicine (TCM) compatibility is difficult to understand. This study combined lipidomics and efficacy-oriented compatibility to explore underlying compatibility mechanisms of Qi Ge decoction (QG) for improving lipid metabolism in hyperlipidemic rats. The QG was divided into three groups according to the efficacy group strategy: the Huangqi-Gegen (HG), Chenpi (CP), and QG groups. Hyperlipidemic rats were treated with QG, HG, CP, or atorvastatin for 3 weeks. The mass spectral data of widely targeted lipidomics were used to evaluate lipid changes. Principal component analysis and orthogonal partial least squares discriminant analysis were used to assess the lipidomic differences between the groups. MetaboAnalyst 5.0 was used to explore metabolic pathways. Compared with the model group, serum cholesterol, triglyceride, and hepatic steatosis were significantly reduced by QG, whereas HG and CP had no significant effects on these indexes. Lipidomics showed that QG, HG, and CP back-regulated 60, 11, and 14 lipids, respectively. Compared with HG and CP, QG had more metabolic targets in diglycerides, triglycerides, ceramides, and phosphatidylethanolamines. Pathway analysis indicated that QG mainly regulated glycerophospholipid and glycerolipid metabolism. This study provided a new method of combining lipidomics and efficacy-oriented compatibility for exploring the scientific connotation of TCM compatibility.

Quantitative multicomponent analysis of a single marker-based simultaneous determination and quality assessment of nucleoside analogs from Qi Zhi capsules.

Qi Zhi capsule (QZC) is approved by the State Drug Administration of China. The QZC consists of nine crude drugs, including astragalus, leeches, ground beetles, curcuma zedoary, hawthorn, semen cassiae, rhizoma sparganii, polygonum multiflorum, and peach kernel, of which leeches and ground beetles are Traditional Chinese Medicine of animal origin. Nucleosides are animal substances with pharmacological effects that are easy to extract and quantify. Different nucleoside analogs in distinct animal-based formulations can be used to characterize animal-based medicines. However, the quality control of a single indicator does not reflect the overall quality of Chinese medicine. Here, we developed a method to simultaneously determine the nucleoside analogs uracil, xanthine, hypoxanthine, uridine, guanine, and uric acid in QZCs using high-performance liquid chromatography. Hypoxanthine was used as an internal reference to determine relative correction factors for the other five components. The six components were determined in ten different batches of QZCs. There was no significant difference between the quantitative multicomponent analysis of a single marker and the external standard method. The relative standard deviation of total nucleosides analogs of 10 batches of samples was 7%. This method can be applied to simultaneously determine multiple active components in QZCs and other nucleoside analog drugs, enabling multi-indicator quality control.

[Network Meta-analysis of Qi-benefiting and blood-activating Chinese patent medicines against ischemic stroke].

This study aimed to compare the efficacy of Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke with network Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library were searched from database inception to October 2022 for randomized controlled trial(RCT) on 11 Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke. The risk of bias plot was made by RevMan 5.3, and network Meta-analysis and efficacy ranking were performed by Stata 17. Ninety-two RCTs were included, involving 10 608 patients. According to the network Meta-analysis, in terms of the clinical total effective rate, surface under the cumulative ranking curve(SUCRA) as followed: Qilong Capsules+conventional western medicine>Zhishe Tongluo Capsules+conventional western medicine>Longshengzhi Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Tongsaimai Tablets+conventional western medicine>Naoan Capsules+conventional western medicine>Naoluotong Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine=Tongxinluo Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine. In terms of the improvement in National Institute of Health stroke scale(NIHSS) score, SUCRA as followed: Longshengzhi Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Naoluotong Capsules+conventional western medi-cine>Tongxinluo Capsules+conventional western medicine>Naoan Capsules+conventional western medicine>Qilong Capsules+conventional western medicine. In terms of safety, the overall adverse reactions/events of Qi-benefiting and blood-activating Chinese patent medicines + conventional western medicine were less than those of the control group. Since Qilong Capsules+conventional western medicine and Zhishe Tongluo Capsules+conventional western medicine were preferred to improve the clinical total effective rate. In the aspect of improving NIHSS score, Longshengzhi Capsules+conventional western medicine and Naomaitai Capsules+conventional western medicine were first options. Due to the lack of direct comparisons between drugs, the overall quality of RCT was not high, so more studies are needed to verify the strength of the evidence.

[Mechanism of tonifying Qi by traditional Chinese medicine from mitochondrial dynamics].

According to the traditional Chinese medicine(TCM) theory, Qi is the essential component maintaining life. Mitochondria are the cellular organelles that generate energy. Qi exhibits abundant common characteristics in bioenergetics compared with mitochondria which control the cellular energy through fusion and fission. Studies have proven that the qi-tonifying function of Chinese medicinal plants and their components facilitates mitochondrial fusion, therefore enhancing ATP synthesis. These studies provide a framework for deciphering the pharmacological mechanisms of Qi-tonifying herbs. This article introduces the common source and function shared by Qi and mitochondria and the regulatory effects of herbal remedies on energy from mitochondria dynamics. This review aims to interpret the connotation of tonifying qi in TCM theory based on the modern biomedical theory.

[Effect of processing with vinegar on efficacy of Curcuma longa in treatment of dysmenorrhea in rats with syndrome of liver depression and Qi stagnation].

This study compared the effects of Curcuma longa before and after processing with vinegar on the rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation to reveal the mechanism of vinegar processing in improving the role of C. longa in soothing liver and relieving pain. The rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation was established according to the Preparation of the Animal Model of Dysmenorrhea(Draft) and the chronic unpredictable stress me-thod. The changes in the body weight, organ indexes, writhing latency, writhing score, and serum levels of six liver function indicators, sex hormones, pain factors, and blood rheological indicators were measured to evaluate the efficacy of C. longa processed with vinegar or not in treating dysmenorrhea in the rats with syndrome of liver depression and qi stagnation. Compared with the model group, the C. longa group(processed with vinegar or not) showed slow weight loss, increase in writhing latency, and decrease in writhing response(P<0.05). The inhibition rates on writhing in raw C. longa, vinegar-processed C. longa, and positive groups were 33.780%, 64.611%, and 62.466%, respectively. The significantly higher inhibition rate of the vinegar processing group indicated that vinegar-processed C. longa demonstrated more significant therapeutic effect. The vinegar-processed C. longa group showed lower levels of alanine aminotransferase(ALT), alkaline phosphatase(ALP), aspartate aminotransferase(AST), direct bilirubin(DBIL), and total bilirubin(TBIL) and higher level of albumin(ALB)(P<0.05), which indicated that vinegar processing enhanced the therapeutic effect of C. longa on liver injury. The serum levels of estradiol(E_2) and oxytocin(OT) were lower in the vinegar-processed C. longa group(P<0.05), indicating that the vinegar-processed C. longa could regulate the sex hormone levels, reduce the activity of uterine smooth muscle and contraction of uterus, and alleviate the symptoms of dysmenorrhea in rats. Moreover, the vinegar-processed C. longa group showed lower interleukin-6(IL-6) and arginine vasopressin(AVP) levels and higher beta-endorphin(ß-EP) level(P<0.05), which indicated that vinegar-processed C. longa regulated the levels of pain factors to exert the pain-relieving effect. Drug intervention decreased the whole blood viscosity low-cut, medium-cut and high-cut values, plasma viscosity, whole blood reduction viscosity low-cut and high-cut values, erythrocyte cumulative pressure, and equation K value of erythrocyte sedimentation rate(P<0.05), and the vinegar-processed C. longa group outperformed other groups. This result indicated that vinegar processing enhanced the function of C. longa in improving the local blood rheology. C. longa processed with vinegar can enter the liver to relieve the da-mage to the heart, liver, kidney, and uterus, repair the liver function, and recover the sex hormone levels and immune function by regulating the levels of sex hormones and pain factors and improving the blood rheology. It activates the pain-relieving mechanism to relieve the pain, protect the liver, and fight inflammation, which is consistent with the theory that vinegar processing facilitates C. longa entering the liver to sooth liver and relieve pain.

[Network Meta-analysis of Qi-supplementing and Yin-nourishing Chinese patent medicines in treatment of early diabetic nephropathy].

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Metabolomics and network pharmacological analysis to explore the mechanism of ginseng treatment for spleen-qi deficiency.

Ginseng is the main Chinese herbal medicine for tonifying Qi and invigorating the spleen. It has been used to treat spleen-qi deficiency with good protective effects for thousands of years, however, its biological mechanism has not been fully elucidated. This study aims to explore the mechanism of ginseng in the treatment of spleen-qi deficiency by using a comprehensive method combining metabolomics and network pharmacological analysis. Gas chromatography-mass spectroscopy was applied for investigating the changes in urine metabolites in spleen-qi deficiency rats and after treatment with ginseng. Metabolomics and network pharmacology analysis were applied to screen potential biomarkers and therapeutic targets of ginseng in the treatment of spleen-qi deficiency, respectively. Molecular docking was employed to further evaluate the docking mode of potential biomarkers and therapeutic target proteins. The results of metabolomics showed that the therapeutic effects of ginseng are mainly related to its regulation of three metabolic pathways. The molecular structure of potential biomarkers and common proteins was further analyzed by molecular docking to verify its effectiveness. Ginseng has good pharmacological effects by controlling key targets of related metabolic pathways, signal pathways, and potential biomarkers.

[Comparison of therapeutic efficacy of Wuling Capsules prepared with different methods for rats with syndrome of liver Qi stagnation, spleen deficiency, and blood stasis].

Wuling Capsules is one of the commonly used drugs for the clinical treatment of chronic hepatitis B with the syndrome of liver Qi stagnation, spleen deficiency, and blood stasis. However, the present preparation method of Wuling Capsules ignores some macromolecules like polysaccharides. In this study, the influences of different ethanol concentrations in the preparation process on the extraction rates of macro-and micro-molecules were investigated. Further, the therapeutic efficacy of Wuling Capsules was evaluated with the reserpine-induced rat model of liver Qi stagnation, spleen deficiency, and blood stasis. When 50% ethanol was used for the last time of extraction, the concentrations of polysaccharides, salvianolic acid B, and schisandrin in the extract, as well as the dry extract yield, increased significantly compared with those of the original preparation method. However, the fingerprints of micro-molecules showed little difference between the two methods, with a similarity of 0.862. The study then set the 50% ethanol extraction as the new preparation method. The pharmacodynamics evaluation showed that the Wuling Capsules prepared with the original and new methods both significantly alleviated the emotional depression and metabolic disturbance in model rats, demonstrating good performance in protecting the rats against gastric mucosal injuries, modulating intestinal function, and activating blood circulation. The mechanism of action may be related to the regulation of gastrointestinal hormone secretion, reduction of inflammation, and promotion of dopamine synthesis in cortex and hippocampus. At the same dose, the Wuling Capsules prepared with the original and new methods showed roughly the same overall therapeutic efficacy. However, the Wuling Capsules prepared with the new method had stronger effect in activating blood circulation and modulating inflammation, but weaker effects in regulating gastrin and dopamine. The present study provides basis data for optimizing the preparation process of Wuling Capsules and deciphering the mechanism of its therapeutic effect on liver Qi stagnation, spleen deficiency, and blood stasis.

[Clinical comprehensive evaluation of Qilong Capsules in treatment of ischemic stroke with Qi deficiency and blood stasis syndrome].

The present study systematically sorted out the existing research on Qilong Capsules in the treatment of ischemic stroke with Qi deficiency and blood stasis syndrome and comprehensively evaluated its clinical evidence and value to highlight the advantages and characteristics of products and provide references for the decision-making of national pharmaceutical management departments. Based on the evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, and pharmacoeconomics, the qualitative and quantitative evaluation of "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, and accessibility, as well as characteristics of traditional Chinese medicine(TCM) was performed with multi-criteria decision analysis(MCDA) mo-del using the information, such as public data, literature data, pharmaceutical research, and questionnaire survey, and CSC v2.0 was used to calculate the clinical value of Qilong Capsules. The evaluation results were grade A, B, C, or D. Spontaneous reporting system(SRS) monitoring data, literature reports, clinical trials, and other multi-source safety evidence showed that the main adverse reactions of this drug included dry mouth, nausea, and rash, and no severe adverse reactions was found. The evidence was sufficient with small and controllable known risks, and the safety was grade A. Meta-analysis showed that Qilong Capsules combined with conventional western medicine in the treatment of acute ischemic stroke was superior to the control group in improving neurological deficits, clinical total response rate, patients' activities of daily living, and hemorheological indexes. The level of evidence was high with manifest clinical significance, and the effectiveness was grade A. The results of pharmacoeconomic research showed that Qilong Capsules combined with conventional western medicine in the treatment of ischemic stroke were advantageous in cost-effectiveness as compared with conventional western medicine alone, but the incremental effect was not significant. The quality evaluation results of the economic report were comparatively clear, and the economy was grade B. Aiming at major cerebrovascular diseases in the society and giving full play to the advantages of TCM, Qilong Capsules focused on the inheritance of classics and scientific and technological innovation, and innovation was grade B. The results of the questionnaire survey showed that the technical characteristics and drug application could meet the medication needs of clinical doctors and patients, and the suitability was grade B. The price level of this drug was comparatively high and the affordability was good since the treatment cost accounted for a small proportion of disposable income. The drug accessibility was good with a wide range of drug sales, sufficient production capacity, and sustainable medicinal materials resources, and was grade B. This drug was derived from the classic prescription Buyang Huanwu Decoction with rich experience of human application, which could regulate Qi and blood circulation, and the section of TCM characteristics was grade B. Based on the evidence evaluation results of "6+1" dimensions of Qilong Capsules, the comprehensive evaluation of clinical value was class A. It is suggested that it can be transformed into relevant policy results of basic clinical medication management according to procedures.

[Effects of Qilong Capsules on myocardial fibrosis and insufficient blood circulation in ischemic cardiomyopathy with Qi deficiency and blood stasis].

Protective effect of Qilong Capsules(QL) on the myocardial fibrosis and blood circulation of rats with coronary heart disease of Qi deficiency and blood stasis type was investigated. Sleep deprivation and coronary artery ligation were used to construct a disease-symptom combination model, and 60 SD rats were divided into sham operation(sham) group, syndrome(S) group, disease and syndrome(M) group and QL group randomly. The treatment group received administration of QL 0.4 g·kg~(-1)·d~(-1). Other groups were given the same amount of normal saline. The disease indexes of each group [left ventricular end diastolic diameter(LVESD), left ventricular end systolic diameter(LVEDD), left ventricular ejection fraction(LVEF), left ventricular axis shortening rate(LVFS), myocardial histopathology, platelet morphology, peripheral blood flow] and syndrome indexes(tongue color, pulse, grip power) were detected. In sham group, cardiomyocytes and myocardial fibers were arranged neatly and densely with clear structures. The tongues' color in sham were light red, and the pulse shape were regular. RGB is a parameter reflected the brightness of the image of the tongue. In the S group, the amplitude and frequency of the animal's pulse increased accompanied by decreasing R,G,B, however, the decreased R,G,B was accompanied by reduced pulse amplitude in M group. And in M group, we observed fuzzy cell morphology, hypertrophied myocytes, disordered arrangement of cardiomyocytes and myocardial fibers, reduced peripheral blood flow and increased collagen volume fraction(CVF). Increased LVESD and LVEDD, and decreased LVEF and LVFS represented cardiac function in S group was significantly lower than that in sham. In QL group, the tongue's color was red and the pulse was smooth. The myocardial fibers of the QL group were arranged neatly and secreted less collagen. It improved the blood circulation in the sole and tail, and reversed the increasing of LVEDD, LVESD and the decreasing of LVEF and LVFS of M group. Platelets in M and S group showed high reactivity, and QL could decrease aggregation risk. In conclusion, Qilong Capsules has an obvious myocardial protective effect on ischemic cardiomyopathy, which may inhibit the degree of myocardial fibrosis and reduce platelet reactivity.

[Pharmacoeconomic evaluation of Qidong Yixin Oral Liquid in treatment of viral myocarditis (Qi-Yin deficiency syndrome) with TreeAge Pro].

To evaluate the pharmacoeconomic value of Qidong Yixin Oral Liquid in the treatment of viral myocarditis(Qi-Yin deficiency syndrome) by supplementing Qi, nourishing the heart, calming the mind, and relieving palpitation, the present study performed the Meta-analysis based on the published papers on Qidong Yixin Oral Liquid by AMSTAR and carried out pharmacoeconomic evaluation using TreeAge Pro by the cost-effectiveness analysis. The results showed that the quality of the included papers was good. After four weeks of treatment, Qidong Yixin Oral Liquid combined with the conventional treatment regimen was superior to the conventional treatment in improving creatine kinase isoenzyme, and the difference was statistically significant. Furthermore, the treatment cost was also higher than that of conventional treatment, with an incremental cost-effectiveness ratio of CNY 95.89, accounting for 0.30% of per capita disposable income. The results of sensitivity analysis showed that the research results were robust. Therefore, based on the assumption that the per capita disposable income in 2020 was the threshold of patients' willingness to pay, it is more economical for patients with viral myocarditis to use Qidong Yixin Oral Liquid combined with conventional secondary prevention regimen than conventio-nal secondary prevention regimen alone. The economic evaluation of Qidong Yixin Oral Liquid in the treatment of viral myocarditis will help physicians and patients choose optimal treatment options, improve rational clinical medication, and provide references for the efficient allocation and utilization of medical resources in China.
