ABSTRACT

Objectif de l'étude.Préciser, chez les diabétiques, la fréquence et les facteurs associés des troubles neurocognitifs. Patients et Méthode. Une étude cas-témoin menée de janvier à décembre 2020 au Centre Neuro-Psychopathologique de l'Université de Kinshasa. Le diabète sucré (DS) a été diagnostiqué selon les critères biologiques de l'OMS et les fonctions neurocognitives évaluées à l'aide du test de Grober et Buschke après un dépistage avec le community screening interview for dementia (CSI-D). Résultats. Cinquante cas et 50 témoins ont été inclus. La fréquence globale des troubles neurocognitifs était de 58%. L'âge moyen des patients diabétiques atteints de troubles neurocognitifs était de 60,48 ± 6,90 ans avec un sex ratio (H/F) de 0,81. Les troubles neurocognitifs étaient en proportion élevés chez les diabétiques qui avaient un DS évoluant entre 6 et 10 ans. Les troubles mnésiques étaient associées au DS ; OR: 3,58, IC 95% [1,29-5,87], p = 0,003 ; avec prédominance d'amnésie d'évocation (65%). Les troubles neurocognitifs chez les diabétiques étaient influencés par l'âge ≥ 60 ans, l'HTA, le manque de ressource sure de revenue financière, les AVC et la durée du diabète supérieure à 5 ans. Le DS demeurait, après ajustement sur différents facteurs, un facteur de risque des troubles neurocognitifs avec un OR ajusté = 3,63, IC 95% [1,86-6,70] et un p = 0, 0001.Conclusion. Les diabétiques sont plus enclins aux troubles neurocognitifs que les non diabétiques. Des facteurs de risque pouvant influencer la survenue de ces troubles ont été identifiés.

ABSTRACT

ObjectiveTo objectively evaluate the clinical efficacy of multiple therapies of traditional Chinese medicine (TCM) in low-prognosis patients who received antagonist protocol for in vitro fertilization and embryo transfer (IVF-ET) again. MethodA total of 128 patients with kidney Yin deficiency, liver depression, and blood stasis who planned to receive antagonist protocol for IVF-ET in the West China Second Hospital of Sichuan University were enrolled and assigned into two groups by random number table method. The observation group (64 casces) was treated by oral administration of Chinese medicine decoction + enema of kidney-tonifying and blood-activating method + auricular point sticking + oral administration of dehydroepiandrosterone (DHEA), while the control group (64 casces) was treated by only oral administration of DHEA. After treatment for three menstrual cycles, both groups received the antagonist protocol for IVF-ET. The TCM syndrome scores, basic sex hormone levels, antral follicle count (AFC), the usage of gonadotropin (Gn), endometrial receptivity indicators, embryo quality indicators, and pregnancy outcomes were compared between the two groups. ResultAfter treatment, the observation group showed decreased follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio, lowered level of estradiol (E2), increased AFC, decreased amount and days of Gn usage, improved endometrial receptivity indicators (endometrial thickness on trigger and ET days, proportion of endometrial type A in endometrial types and the level of E2 on trigger day) and embryo quality indicators (the rates of mature follicles, fertilization, normal fertilization, and premium embryos), and decreased TCM syndrome scores (P<0.05, P<0.01). Moreover, the observation group had lower FSH/LH ratio, E2 level, and amount of Gn usage, higher AFC, poorer endometrial receptivity and embryo quality indicators, and lower TCM syndrome scores than the control group after treatment (P<0.05, P<0.01). In addition, except for 3 cases of natural pregnancy, the observation group outperformed the control group in terms of improving the clinical pregnancy rates during initiation cycle and transplantation cycle and clinical pregnancy rate and decreasing biochemical pregnancy rate and early abortion rate (P<0.05). ConclusionCombined therapies of TCM can alleviate the clinical symptoms, reduce TCM syndrome scores, reduce the Gn usage amount, improve the number and quality of embryos and endometrial receptivity, and coordinate the synchronous development of endometrium and embryo. In this way, they can increase the clinical pregnancy rate and reduce biochemical pregnancy rate and early abortion rate in the low prognosis patients with kidney yin deficiency, liver depression, and blood stasis who are undergoing IVF-ET again.

ABSTRACT

Based on the interaction between supramolecule of traditional Chinese medicine and enterobacteria, the material basis of Rhei Radix et Rhizoma and Coptidis Rhizoma was explored. Scanning electron microscopy (SEM) and dynamic light scattering (DLS) were used to characterize the morphological differences of Rhubarb single decoction, Coptis single decoction and Rhubarb and Coptis co-decoction. An in vitro antibacterial model (E. coli, E. faecium and B. subtilis) was established to evaluate the damage effect of the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma on enterobacteria. Ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to analyze the changes of chemical components of single decoctions and co-decoctions. The co-decoction of Rhei Radix et Rhizoma and Coptidis Rhizoma was turbid after decocting. The spherical particles of 300-400 nm were observed under SEM, and the co-decoction was more uniform and stable than that of single decoction. The interaction between supramolecules formed after the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma and enterobacteria was significantly different from that of single decoction. In the process of interaction between supramolecules and enterobacteria, the spherical state was maintained, and the medicinal ingredients in Coptidis Rhizoma or Rhei Radix et Rhizoma were blocked, which could effectively alleviate the damage to enterobacteria. This study provided a reference for subsequent studies on the regulation of intestinal flora homeostasis by the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma.

ABSTRACT

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma(GRR) decoction pieces produced by fresh and traditional cutting, and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process, and high performance liquid chromatography(HPLC) fingerprint of the standard decoction was established and performed on an Agilent EC-C18 column(4.6 mm×150 mm, 2.7 μm) with acetonitrile(A)-0.1% phosphoric acid aqueous solution(B) as the mobile phase for gradient elution(0-23 min, 18%-21%A; 23-35 min, 21%-28%A; 35-80 min, 28%-32%A), and the detection wavelength was 203 nm. Then similarity evaluation, principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection(VIP) value>1. Quantitative analysis was carried out on the screened known differential components, and combined with the indicators of the dry extract rate and the transfer rate, to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950, and 18 common peaks were identified, including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg1, Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces, while the contents of ginsenoside Rb1, Rc , Rb2 and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg1, Re, Rb1 and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces, while the contents of ginsenoside Rc , Rb2 and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces, the average transfer rates of ginsenoside Rg1, Rb1, Rc, Rb2 and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased(P<0.05), and the average transfer rate of ginsenoside Re and Rd also increased, but the difference was not statistically significant. ConclusionThe dry extract rate, content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces, which can provides data support for the subsequent clinical application of fresh cutting products.

ABSTRACT

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine (TCM) multi-channel intervention on the ovarian function,TCM syndromes and natural conception of poor ovarian responders(kidney-Yin deficiency,liver depression and blood stasis pattern) who planned to receive another in vitro fertilization embryo transfer(IVF-ET)antagonist regimen. MethodThe 128 low-prognosis patients (kidney Yin deficiency,liver depression and blood stasis pattern) who attended the West China Second University Hospital, Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected,and then divided into the treatment group and the control group according to the random number table,with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone(DHEA),while the treatment group was treated with multi-channel TCM(oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema). After 3 menstrual cycles,the relevant indicators for ovarian function evaluation,TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment,the basal follicle stimulating hormone(bFSH),bFSH/basal luteinizing hormone(bLH),basal estradiol(bE2),antral follicle count(AFC),the number of oocytes obtained,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment(P<0.05,P<0.01). For the control group, the bFSH/bLH and TCM syndrome scores were increased after treatment(P<0.05), while the bFSH,bFSH/bLH,bE2,AFC,the number of oocytes obtained,the number of normal fertilization,and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment,bFSH,bFSH/bLH,bE2,AFC,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were better (P<0.05,P<0.01),while there was no significant difference in the number of oocytes obtained. After treatment,there were 3 cases of natural conception in the treatment group,while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency,liver depression and blood stasis pattern,multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH,bFSH/bLH values,improve the levels of bE2,increase AFC,the number of oocytes obtained,the number of normal fertilization and the number of superior embryos,improve ovarian function,menstruation and TCM syndromes,improve their quality of life,and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

ABSTRACT

ObjectiveThis study aims to examine the effect of Rhei Radix et Rhizoma-Coptidis Rhizoma on reducing insulin resistance in db/db mice by regulating the adenylate activated protein kinase (AMPK)/UNC-51-like kinase 1 (ULK1)/key molecule of autophagy, benzyl chloride 1 (Beclin1) pathway and elucidate the underlying mechanism. MethodSixty 6-week-old male db/db mice were studied. They were randomly divided into the model group, metformin group (0.26 g·kg-1), and low-, middle-, and high-dose groups (2.25, 4.5, 9 g·kg-1) of Rhei Radix et Rhizoma-Coptidis Rhizoma. A blank group of db/m mice of the same age was set, with 12 mice in each group. After eight weeks of continuous intragastric administration, the blank group and model group received distilled water intragastrically once a day. The survival status of the mice was observed, and fasting blood glucose (FBG) was measured using a Roche blood glucose device. Fasting serum insulin (FINS) was measured using an enzyme-linked immunosorbent assay, and the insulin resistance index (HOMA-IR) was calculated. Hematoxylin-eosin (HE) staining was performed to observe the pathological changes in the liver of the mice. The protein expression levels of AMPK, Beclin1, autophagy associated protein 5 (Atg5), and p62 in liver tissue were determined by using Western blot. The protein expression levels of autophagy associated protein 1 light chain 3B (LC3B) and ULK1 in liver tissue were determined using immunofluorescence. Real-time fluorescence quantitative PCR (Real-time PCR) was used to measure mRNA expression levels of AMPK, Beclin1, Atg5, ULK1, and p62. ResultCompared with the blank group, the model group exhibited a significant increase in body mass (P<0.01). Additionally, the levels of FBG, FINS, and HOMA-IR significantly changed (P<0.01). The structure of liver cells was disordered. The protein expression levels of AMPK, Beclin1, and Atg5 in liver tissue were significantly decreased (P<0.01), while the expression level of p62 protein was significantly increased (P<0.01). The expression levels of mRNA and proteins were consistent. Compared with the model group, the body mass of the metformin group and high and medium-dose groups of Rhei Radix et Rhizoma-Coptidis Rhizoma was significantly decreased (P<0.05). FBG, FINS, and HOMA-IR were significantly decreased (P<0.05,P<0.01). After treatment, the liver structure damage in each group was alleviated to varying degrees. The protein expressions of AMPK, Beclin1, Atg5, LC3B, and ULK1 were increased (P<0.05,P<0.01), while the protein expression of p62 was decreased (P<0.01). The expression levels of mRNA and proteins were generally consistent. ConclusionThe combination of Rhei Radix et Rhizoma-Coptidis Rhizoma can effectively improve liver insulin resistance, regulate the AMPK autophagy signaling pathway, alleviate insulin resistance in db/db mice, and effectively prevent the occurrence and development of type 2 diabetes.

ABSTRACT

By reviewing the ancient and modern literature, the name, origin, scientific name evolution, place of origin, quality, harvesting, processing, efficacy and toxicity of Asteris Radix et Rhizoma(ARR) were systematically sorted out, so as to provide reference for the development and utilization of the relevant famous classical formulas. According to textual research, ARR was first contained in Shennong Bencaojing, all generations are Ziwan for its proper name, and there are still aliases such as Ziyuan, Ziqian and Xiaobianer. Its mainstream origin in successive generations was Aster tataricus, and there are also Ligularia fischeri and others in local area of use. The medicinal parts of ARR are root and rhizome, but in modern times, the rhizome is mostly used for propagation and cultivation, so some of ARR medicinal materials only have the root without the rhizome. The earliest recorded ancient origin of ARR was now Fangxian(Hubei), Zhengding and Handan(Heibei), then the range of production areas gradually expanded, the mainstream production areas from the Song dynasty to the Ming and Qing dynasties included Hebei, Jiangsu, Anhui, Henan and other places, since modern times, two major producing areas have been formed in Anguo, Hebei province and Bozhou, Anhui province. From the quality evaluation, it is clear that from ancient times, flexible roots and purple color are the best. The ancient harvesting was mainly in lunar February or March, and then dried in the shade, and the modern harvesting is mostly in spring and autumn, and the roots are braided into pigtails and then dried in the sun or dried in the sun after 1-2 d. The ancient and modern processing method of ARR are basically the same, mainly honey processing, there are still methods of frying, steaming, vinegar sizzling, etc. Based on the results, it is recommended that the dried roots and rhizomes of A. tataricus should be used in clinical and the development of related famous classical formulas, and those whose original formulas specify the processing requirements can be processed according to the relevant requirements, while whose processing requirements are not specified should be used in the form of raw products.

ABSTRACT

OBJECTIVE@#Angelicae Sinensis Radix (ASR, Danggui in Chinese), Cistanches Herba (CH, Roucongrong in Chinese), Ginseng Radix et Rhizoma (PG, Renshen in Chinese), and Panacis Quinquefolii Radix (PQ, Xiyangshen in Chinese), widely used as medicine and dietary supplement around the world, are susceptible to fungal and mycotoxin contamination. In this study, we aim to analyze their fungal community by DNA metabarcoding.@*METHODS@#A total of 12 root samples were collected from three main production areas in China. The samples were divided into four groups based on herb species, including ASR, CH, PG, and PQ groups. The fungal community on the surface of four root groups was investigated through DNA metabarcoding via targeting the internal transcribed spacer 2 region (ITS2).@*RESULTS@#All the 12 samples were detected with fungal contamination. Rhizopus (13.04%-74.03%), Aspergillus (1.76%-23.92%), and Fusarium (0.26%-15.27%) were the predominant genera. Ten important fungi were identified at the species level, including two potential toxigenic fungi (Penicillium citrinum and P. oxalicum) and eight human pathogenic fungi (Alternaria infectoria, Candida sake, Hyphopichia burtonii, Malassezia globosa, M. restricta, Rhizopus arrhizus, Rhodotorula mucilaginosa, and Ochroconis tshawytschae). Fungal community in ASR and CH groups was significantly different from other groups, while fungal community in PG and PQ groups was relatively similar.@*CONCLUSION@#DNA metabarcoding revealed the fungal community in four important root herbs. This study provided an important reference for preventing root herbs against fungal and mycotoxin contamination.

ABSTRACT

OBJECTIVE@#Based on metabonomics technology of high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) and hydrogen nuclear magnetic resonance spectroscopy (1H NMR), the pharmacokinetic characteristics and therapeutic mechanism of Rhei Radix et Rhizoma (RhRR, Dahuang in Chinese), Eupolyphaga Steleophaga (EuS, Tubiechong in Chinese) combined with RhRR acting on acute liver injury were explored.@*METHODS@#Models of acute liver injury were established, and the pharmacokinetic methods of five components of RhRR-EuS in rats were found by HPLC-MS/MS. The liver tissues of different groups of mice were analyzed by 1H NMR spectroscopy combined with multivariate statistical analysis to investigate the metabolomics of RhRR-EuS and RhRR.@*RESULTS@#Pharmacokinetic results showed there were different levels of bimodal phenomenon in different groups, and the absorption of free anthraquinone in RhRR increased after compatibility with EuS. In addition, the pathological state of acute liver injury in rats can selectively promote the absorption of emodin, chrysophanol, physcion and aloe emodin. Through 15 differential metabolites in the liver tissue of acute liver injury mice, it was revealed that RhRR-EuS and RhRR could protect the liver injury by regulating the metabolism of glutamine and glutamic acid, alanine, aspartic acid and glutamic acid, and phosphoinositide. However, the regulation of RhRR was weaker than that of RhRR-EuS.@*CONCLUSION@#For the first time, we studied the pharmacokinetics and metabolomics differences of RhRR-EuS and RhRR in rats and mice with acute liver injury, in order to provide theoretical reference for clinical treatment of liver disease by DHZCP.

ABSTRACT

Ginseng Radix et Rhizoma(GRR) has the function of replenishing vital energy and can lighten the body and prolong the life when taken for a long time, which is suitable for the development of anti-aging products, so this paper intends to sort out the progress of anti-aging research on GRR. After combing, the results of modern studies have shown that a variety of components in GRR have anti-aging effect, which can prolong the lifespan of aging animal models, as well as delay the aging of various systems. The anti-aging mechanisms mainly include anti-cellular senescence, anti-oxidative stress, inhibiting telomere shortening, maintaining mitochondrial homeostasis and so on. The anti-aging ingredients of GRR involved in the researches mainly include ginsenoside Rg1 and ginsenoside Rb1, in addition, ginsenoside Rg3, ginsenoside Rd, ginsenoside Rg2, ginsenoside Re, ginsenoside Rb2, oligosaccharides of GRR, polysaccharides of GRR, water extract of GRR, total saponins of Panax ginseng stems and leaves are also included. Therefore, under current background of population aging, the in-depth development of GRR and its transformation into anti-aging products are of great significance for delaying senility and improving the health conditions of aging population.

ABSTRACT

ObjectiveTo observe the effects of Hirudo, Notoginseng Radix et Rhizoma, and drug pair on renal pathological morphology and protein phosphatase 2A (PP2A)/adenylate activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signal pathway in rats with chronic renal failure (CRF). MethodThe 55 male SD rats were randomly divided into a normal group (n=11) and a modeling group (n=44). The normal group was fed conventionally, and the modeling group was given 0.25 g·kg-1·d-1 adenine by gavage for 28 days to replicate the CRF model. After successful modeling, rats were randomly divided into model group, Hirudo group (3 g·kg-1·d-1), Notoginseng Radix et Rhizoma group (3 g·kg-1·d-1), and Hirudo + Notoginseng Radix et Rhizoma group (3 g·kg-1·d-1), with 9 rats in each group. The normal group and model group were given a constant volume of normal saline by intragastric administration for 30 days. At the end of the experiment, the levels of serum creatinine (SCr) and urea nitrogen (BUN) in all groups were measured. The renal pathological morphology changes were observed by hematoxylin-eosin (HE) staining, Masson staining, and electron microscopy. The mRNA expressions of PP2A, AMPK, and mTOR were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of PP2A, AMPK, phosphorylation(p)-AMPK, mTOR, and p-mTOR in renal tissue were detected by Western blot. ResultCompared with the normal group, the renal pathological structure changes were obvious, and the levels of SCr and BUN were significantly increased. The mRNA expression of PP2A, protein expression of PP2A, and p-mTOR/mTOR expression were significantly increased, and the p-AMPK/AMPK was significantly decreased in the model group (P<0.05). Compared with the model group, the renal pathological morphology changes were significantly improved, and the levels of SCr and BUN were significantly decreased. The mRNA expression of PP2A, protein expression of PP2A, and p-mTOR/mTOR expression in the renal tissue were significantly decreased, and the p-AMPK/AMPK was significantly increased (P<0.05) in all groups after drug intervention. In addition, the effect in the Hirudo+Notoginseng Radix et Rhizoma group was better. The mRNA expression levels of AMPK and mTOR in the renal tissue were not significantly different among the normal group, model group, and other groups. ConclusionThe efficacy of Hirudo and Notoginseng Radix et Rhizoma pairs in improving renal fibrosis in rats with CRF is significantly better than that of the single drug, and its improvement on renal fibrosis in rats with CRF may be related to the regulation of PP2A/AMPK/mTOR signaling pathway.

ABSTRACT

Introduction: the first COVID-19 case in Brazil was confirmed on February 26, 2020. As of March 17, 2023, the Ministry of Health reported 699,634 deaths from COVID-19, with a case fatality rate of 1.9%. The impact of the COVID-19 pandemic in Brazil extends to socioeconomic and healthcare systems, reflecting significant regional disparities. Objective: To analyze mortality, incidence, and case fatality rates for COVID-19 in the states of Paraná and Santa Catarina, in the southern region of Brazil. Methods: This is an ecological time-series study using official Brazilian secondary data for COVID-19 cases and deaths. Data were extracted from the dashboard of the State Health Department of Santa Catarina and Paraná. Temporal series were developed for trend analysis using the Prais-Winsten regression model. Statistical analyses were performed using STATA 14.0 software (College Station, TX, USA, 2013). Results: In the analysis of rates over the entire period, trends for mortality, case fatality, and incidence in the state of Santa Catarina are decreasing, decreasing, and stationary, respectively. In Paraná, rates over the entire period showed a stationary trend for mortality, decreasing for case fatality, and increasing for incidence. Conclusion: COVID-19 had a devastating effect on the states of Santa Catarina and Paraná. Both states experienced the progression of the COVID-19 pandemic, with higher case fatality and mortality rates observed in Paraná, while Santa Catarina had a higher incidence rate over the three years of the COVID-19 pandemic.

ABSTRACT

This study used metabolomics to explore the improvement effect of raw and honey-processed Glycyrrhizae Radix et Rhizoma on acute kidney injury (AKI) in rats. All animal experiments were approved by the Animal Ethics Committee of Shandong Academy of Chinese Medicine (approval No.: SDZYY20200101001). SD rats were randomly divided into normal group, model group, raw Glycyrrhizae Radix et Rhizoma group (0.9 g·kg-1) and honey-processed Glycyrrhizae Radix et Rhizoma group (0.9 g·kg-1), 6 rats in each group. The rats model of acute kidney injury was established by single intraperitoneal injection of cisplatin (CP) and treated with raw and honey-processed Glycyrrhizae Radix et Rhizoma. The pathological changes of renal tissue were evaluated by hematoxylin and eosin (HE) and PAS staining, the contents creatinine (Cr), blood urea nitrogen (BUN) and superoxide dismutase (SOD) in serum were detected. UPLC-Q-TOF/MS was used to study tissue metabolomics to screen the biomarkers affected by raw and honey-processed Glycyrrhizae Radix et Rhizoma and analyz the metabolic pathways. The results showed that compared with the model group, raw and honey-processed Glycyrrhizae Radix et Rhizoma can significantly improve the pathological changes of renal tissue and decrease the content of Cr, BUN and increase the activity of SOD. In addition, honey-processed Glycyrrhizae Radix et Rhizoma can also significantly reduce the kidney index. In tissue samples, 45 biomarkers were measured in AKI rats. Raw Glycyrrhizae Radix et Rhizoma and honey-processed Glycyrrhizae Radix et Rhizoma could simultaneously call back 11 differential metabolites, which were involved in the regulation of glycerophospholipid metabolism, tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and glutathione metabolism. In addition, raw Glycyrrhizae Radix et Rhizoma is also involved in the regulation of glycine, serine and threonine metabolism and pyrimidine metabolism. In summary, raw and honey-processed Glycyrrhizae Radix et Rhizoma can participate in the regulation of different metabolic pathways, and play an improvement role in AKI rats by regulating amino acid, lipid metabolism, energy metabolism and oxidative stress.

ABSTRACT

Cerebral hemorrhage accounts for about 10%-15% of all strokes, and its pathogenesis is complex. Currently, the main clinical treatment is mainly medical symptomatic treatment, including the use of antihypertensive drugs, hypoglycemic drugs, and hemostatic drugs, and surgical treatment is required in some cases, but there is still a lack of effective treatment. In recent years, traditional Chinese medicine and proprietary Chinese medicine have been widely accepted for their stable efficacy, high safety, and low cost. Rhei Radix et Rhizoma is one of the most commonly used herbal medicines for the treatment of cerebral hemorrhage. This paper summarizes the relevant literature on the treatment of cerebral hemorrhage with Rhei Radix et Rhizoma and finds that its active ingredients are mainly anthraquinones, such as emodin, Rhei Radix et Rhizoma acid, and Rhei Radix et Rhizoma phenol. The herbal formulas are Da Chengqitang, Shengdi Dahuangtang, Liangxue Tongyufang, and Naoxueshu oral liquid. The effects involve protecting the blood-brain barrier, promoting hematoma absorption, reducing inflammation levels, decreasing lactic acid accumulation at the bleeding site, and increasing the expression of brain-derived neurotrophic factors. The pathways involved include aquaporin 4 (AQP4), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), extracellular signal-regulated kinase 1/2 (ERK1/2), Toll-like receptor 4 (TLR4), nuclear transcription factor-κB (NF-κB), nuclear factor E2-related factor 2 (Nrf2), and Wnt3a/β-linked protein pathway. This paper summarizes the progress of clinical studies and animal experiments on the treatment of cerebral hemorrhage with active ingredients of Rhei Radix et Rhizoma and herbal compounds containing Rhei Radix et Rhizoma, so as to provide a reference for the treatment protocol of cerebral hemorrhage.

ABSTRACT

ObjectiveTo investigate the principle and scientific connotation of Euodiae Fructus(EF) processed with Glycyrrhizae Radix et Rhizoma(Gly) by comparing the effects of unprocessed products of EF(UEF) and processed products of EF with the different proportions of Gly(GEFs) at toxic doses on oxidative stress and autophagy in the liver of mice. MethodSeventy mice were randomly divided into 7 groups, namely the control group, the UEF group, the group of the processed products of EF without Gly(PEF) and 4 groups of GEFs(the mass ratios of EF to Gly were 100∶3, 100∶6, 100∶12 and 100∶24, respectively, hereinafter referred to as the processed products of EF with the mass ratios of 100∶3, 100∶6, 100∶12 and 100∶24 of Gly). The mice were given purified water, the decoction of UEF, PEF and GEFs by gavage at a dose of 30 g·kg-1. PEF and GEFs were prepared according to the method under EF in the 2020 edition of Chinese Pharmacopoeia. Levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined by ultraviolet-visible spectrophotometry, hematoxylin-eosin(HE) staining was used to evaluate the pathological changes of liver tissue, the level of reactive oxygen species(ROS) was detected by fluorescence method, the mRNA expression of heme oxygenase-1(HO-1), quinone oxidoreductase-1(NQO1), glutathione-S-transferase 1(GSTA1), Kelch-like epichlorohydrin-associated protein 1(Keap1) and p62 were measured by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR), western blot was used to detect the protein expression of phosphorylated mammal target of rapamycin(p-mTOR), phosphorylated ribosomal p70 S6 protein kinase(p-p70S6K), p62, microtubule-associated protein 1 light chain 3Ⅰ(LC3Ⅰ) and LC3Ⅱ. ResultCompared with the control group, after 7 d of administration, the increase in body mass of mice in the UEF group began to slow down and the difference gradually increased, and the liver body index significantly increased(P<0.01), pathomorphological observation showed that the structure of hepatic lobules was disordered, and local hepatic sinuses were narrowed or disappeared, and there were inflammatory infiltration and local bleeding, the levels of ALT and AST in serum and ROS in liver tissue were significantly increased(P<0.01), and the expressions of Keap1, HO-1, NQO1, GSTA1, p62 mRNA and p-mTOR, p-p70S6K, p62 protein in liver tissue were significantly decreased(P<0.01), and LC3Ⅱ/LC3Ⅰ was significantly increased(P<0.01). Compared with the UEF group, the body mass of mice increased, and the liver body index, the levels of ALT and AST in serum, and the level of ROS in liver tissue all decreased in the groups of PEF and GEFs. Among these groups, only the liver lobules in GEF(100∶6) group were intact, and the size of liver sinuses was close to that in the control group. The mRNA expressions of Keap1, HO-1, NQO1, GSTA1 and p62 in liver tissue showed an overall upward trend in the groups of PEF and GEFs. Among these groups, only the ones of the above mRNA in the GEF(100∶6) group had a significant increase(P<0.05, P<0.01). The protein expressions of p-mTOR, p-p70S6K, p62 and LC3Ⅱ/LC3Ⅰ had a callback in the groups of PEF and GEFs, of which the protein expressions of p-mTOR, p-p70S6K and LC3Ⅱ/LC3Ⅰ in the GEF(100∶6) group and the expression of p62 protein in the GEF(100∶24) group had the largest callback. Except for p-mTOR protein, other protein expressions were statistically significant(P<0.05, P<0.01). ConclusionThe hepatotoxicity of EF is closely related to its ability to induce oxidative stress, which leads to pathological autophagy and hepatocyte damage. This ability can be reduced by the processing with different proportions of Gly, especially the ratio of 100∶6.
