ABSTRACT

Liquid chromatography-mass spectrometry was employed to analyze the chemical components in Curcuma longa tuberous roots(HSYJ), C. longa tuberous roots processed with vinegar(CHSYJ), and rat serum after the administration. The active components of HSYJ and CHSYJ absorbed in serum were identified based on the secondary spectrum of database and literature. The targets of primary dysmenorrhea was screened out from database. The protein-protein interaction network analysis, gene ontology(GO) functional annotation, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed for the common targets shared by the drug active components in serum and primary dysmenorrhea, and the component-target-pathway network was constructed. AutoDock was used to conduct molecular docking between the core components and targets. A total of 44 chemical components were identified from HSYJ and CHSYJ, including 18 absorbed in serum. On the basis of network pharmacology, we identified 8 core components(including procurcumenol, isobutyl p-hydroxybenzoate, ferulic acid, and zedoarondiol) and 10 core targets \[including interleukin-6(IL-6), estrogen receptor 1(ESR1), and prostaglandin-endoperoxide synthase 2(PTGS2)\]. The core targets were mainly distributed in the heart, liver, uterus, and smooth muscle. The molecular docking results showed that the core components were well bound to the core targets, indicating that HSYJ and CHSYJ may exert therapeutic effect on primary dysmenorrhea via estrogen, ovarian steroidogenesis, tumor necrosis factor(TNF), hypoxia-inducible factor-1(HIF-1), IL-17 and other signaling pathways. This study clarifies the HSYJ and CHSYJ components absorbed in serum, as well as the corresponding mechanism, providing a reference for further elucidating the therapeutic material basis and clinical application of HSYJ and CHSYJ.

ABSTRACT

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(β-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.

ABSTRACT

Objective:To observe the effect of Wuzi Yanzong Wan made of different processed products on the apoptosis of spermatogenic cells in rats with kidney essence deficiency, and explore its protective effect on spermatogenic cells. Method:SD rats were randomly divided into the blank group, model group, whole raw product group, pharmacopoeia group and salt-processed product group, with 8 rats in each group. The kidney essence deficiency model was replicated by giving tripterygium glycoside tablets (the dose of 20 mg·kg<sup>-1</sup>). The flow cytometry (FCM) was used to analysis the apoptosis of spermatogenic cells in testis, the immunohistochemistry (IHC) and Western blot were used to detect the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) in the testis. High performance liquid chromatography (HPLC) was used to compare the contents of eight components (chlorogenic acid, ellagic acid, hyperoside, isoquercitrin, verbascoside, astragalin, kaempferol and schisandrin) in Wuzi Yanzong Wan made of different processed products, the mobile phase was composed of acetonitrile (A)-0.4% phosphoric acid aqueous solution (B) for gradient elution (0-5 min, 5%-15%A; 5-10 min, 15%-17%A; 10-25 min, 17%A; 25-35 min, 17%-26%A; 35-60 min, 26%-56%A), the detection wavelength was set at 254 nm. Result:Compared with the model group, the total apoptosis rate of spermatogenic cells, protein expression of Bax and Bcl-2 in each administration group were improved. Among them, the pharmacopoeia group and salt-processed product group had significant effects (<italic>P</italic><0.01), and the improvement effect of the pharmacopoeia group and salt-processed product group was significantly better than that of the whole raw product group (<italic>P</italic><0.05). The contents of chlorogenic acid, hyperoside, isoquercitrin and verbascoside in Wuzi Yanzong Wan were increased after the herbal medicines being processed with salt-water. The content of ellagic acid in the salt-processed product group increased, while it decreased in the pharmacopoeia group. The contents of verbascoside, astragalin, kaempferol and schisandrin in samples from the salt-processed product group were greater than those in samples from the pharmacopoeia group. Conclusion:Wuzi Yanzong Wan may reduce the apoptosis of spermatogenic cells in rat testis by inhibiting the expression of Bax and promoting the expression of Bcl-2, and exert its effect of nourishing kidney and enriching essence. The enhanced anti-spermatogenic effect of Wuzi Yanzong Wan after processing may be related to the changes in chemical composition content after processing.

ABSTRACT

To determine the content of extracts in different processed products of Chuanxiong Rhizoma and the content of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, in order to study the effect of different proces-sing methods on the alcohol-soluble extract and the content of six ingredients of Chuanxiong Rhizoma. The extract was determined according to the alcohol-soluble extract determination method set forth in item 2201 of the 2020 Chinese Pharmacopoeia Ⅳ; the content was determined by using Agilent TC-C_(18) column(4.6 mm×250 mm, 5 μm) for gradient elution, with acetonitrile(A)-0.5% acetic acid solution(B) as the mobile phase; the column temperature was at 30 ℃; the flow rate was 1.0 mL·min~(-1), the detection wavelength was 285 nm; and the injection volume was 10 μL. Compared with Chuanxiong Rhizoma, the extracts of processed products all increased significantly; by the degree of increase, the order was stir-frying Chuanxiong Rhizoma with honey>stir-frying Chuanxiong Rhizoma with rice wine>stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction>stir-frying Chuanxiong Rhizoma with tea decoction; the HPLC method was convenient and reliable, with a high linear relationship of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, and a high precision, repeatability, stability and the sample recovery rate in Chuanxiong Rhizoma and its processed products. There were 15 chromatographic peaks before and after processing, eight of them were identified. Compared with the pre-processing, two chromatographic peaks were added after the stir-frying with honey and rice wine; and four chromatographic peaks were added after the processing with Angelicae Dahuricae Radix decoction; the contents of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A, and ligustilide in stir-frying Chuanxiong Rhizoma with rice wine were all reduced. Except for the content of ferulic acid that increased, the content of the other five components decreased in stir-frying Chuanxiong Rhizoma with honey, stir-frying Chuanxiong Rhizoma with tea decoction, and stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction. Rice wine, honey, decoction of tea and Angelicae Dahuricae Radix could all promote the dissolution of chemical components in Chuanxiong Rhizoma, and increase the content of extract; the changes in the contents of six components of different processed products could provide a certain basis for studying chemical composition and efficacy of different processed products of Chuanxiong Rhizoma.

ABSTRACT

OBJECTIVE@#To investigate whether Ershen Pill (ESP, ) could alleviate the symptom of Pi (Spleen)-Shen (Kidney) yang deficiency (PSYD)-induced diarrhea in rat model and explore its anti-diarrhea mechanism.@*METHODS@#Seventy-five Sprague-Dawley rats were divided into 5 groups by a random number table, including control, positive, model, low-dose (LD) and high-dose (HD) ESP groups, 15 rats in each group. All the rats, except those in the control group, were developed PSYD induced-diarrhea based on its pathology and etiology. The rats in positive, LD and HD ESP groups were treated with Shenling Baizhu Pill (), LD (1.05 g/kg) or HD (3.50 g/kg) ESP petroleum ether extract once a day for 2 weeks, respectively. Body weight change and diarrhea index were measured. The histology scores of the kidney were evaluated via hematoxylin and eosin (HE) staining. Aquaporin-3 (AQP3) expression in the colon was analyzed by immunofluorescence, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot, respectively.@*RESULTS@#Compared with the model group, oral administration of LD and HD ESP prevented body weight loss and inhibited diarrhea after 2-week treatment (P<0.05). Kidney deterioration was impeded, and the histology score in LD and HD ESP groups were 8.2 and 10.5, respectively, which were both higher than those in the model group (P<0.05). In addition, ESP treatment alleviated rat colitis, and HD ESP significantly improved the AQP3 positive staining intensity in the colon tissue compared with the model group. The result from Western blot revealed that AQP3 protein synthesis in colon tissue of LD and HD ESP groups increased by 2.1- and 5.9-fold compared with the model group (P<0.05). qRT-PCR result showed that AQP3 gene expression in the HD ESP group was also up-regulated by 2.5-fold normalized to the model group (P<0.05).@*CONCLUSION@#ESP extract effectively alleviates the symptoms of PSYD and relieves PSYD-induced diarrhea by improving AQP3 synthesis in the colon.

ABSTRACT

Objective: To investigate the effect of Coptidis Rhizoma on intestinal microflora of normal and type 2 diabetic rats before and after being steamed with rice wine based on 16S rRNA sequencing technology. Method: The type 2 diabetic rat model was established by high-fat diet and streptozotocin. Normal and model rats were given the decoction of Coptidis Rhizoma or Coptidis Rhizoma steamed with rice wine every day (0.8 g·kg-1, according to raw drug quantity), the positive drug group was given metformin solution every day (0.25 g·kg-1), continuous administration for 30 d. Blood glucose was measured once a week and oral glucose tolerance was measured on the 27th day of administration. On the 30th day, feces were taken and the rats were anesthetized. Blood was taken for enzyme linked immunosorbent assay (ELISA). Colon was dissected for hematoxylin-eosin (HE) staining. Based on 16S rRNA gene sequencing technology, the alpha diversity, beta diversity, abundance and composition, and the correlation with anti-inflammatory and antioxidant activities of intestinal microflora were comprehensively analyzed and evaluated. Result: After giving normal rats Coptidis Rhizoma or Coptidis Rhizoma steamed with rice wine, there were some inflammatory reactions, imbalance of oxidation-antioxidant system, pathological damage of colon and changes of intestinal microflora, which showed some toxic and side effects, but the toxic and side effects of Coptidis Rhizoma steamed with rice wine were lower than those of Coptidis Rhizoma. Coptidis Rhizoma could reduce fasting blood glucose and improve glucose tolerance in type 2 diabetic rats before and after steaming. Although the effect of Coptidis Rhizoma steamed with rice wine had an increasing trend, there was no significant difference between before and after processing. Type 2 diabetic rats appeared mild inflammation and imbalance of oxidation-antioxidant system, characterized by significant increase of contents of interleukin (IL)-6, nuclear transcription factor (NF)-κB and malondialdehyde (MDA) (PPPConclusion: Coptidis Rhizoma can treat type 2 diabetic rats by regulating intestinal microflora before and after steaming with rice wine, and the effect of Coptidis Rhizoma steamed with rice wine is better. The toxic and side effects of Coptidis Rhizoma on intestinal flora are reduced by steamed with rice wine. The processing mechanism of increasing efficacy and decreasing toxicity of Coptidis Rhizoma steamed with rice wine is closely related to intestinal microflora.

ABSTRACT

As one of the three pillars of Chinese medicine industry, traditional Chinese medicines prepared in ready-to-use forms are important raw materials for clinical medication and production of Chinese patent drugs. By considering the literature of Curcumae Radix, a multi-source Chinese herb and the situation of market investigation, the modern evaluation method based on traditional grading was introduced for comprehensive evaluation of the processed Curcumae Radix. The correlation between traditional grading method and modern evaluation index was explored to establish the grading standard of Curcumae Radix. According to the comprehensive evaluation, Curcumae Radix was divided into four grades: superior, first, second and third grades under the guidance of the theory of traditional Chinese medicine. This study provides a new idea for the grading of multi-source processed Chinese medicine, achieving high quality and good price, which is helpful to improve the clinical efficacy.

ABSTRACT

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

ABSTRACT

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

ABSTRACT

Untargeted metabolomics analysis of rhubarb and stewed rhubarb samples shows that the determined samples clearly clustered in to two groups, indicating that the processing procedures caused changes in the composition and/or content of components in rhubarb. Ten components were identified by UHPLC-Q-TOF-MS/MS and references, which intensity declined in rhubarb after processing. Targeted metabolomics analysis of rhubarb and stewed rhubarb samples indicated that aloe-emodin, rhein, emodin and physcion were detected with lower intensity in stewed rhubarb samples than in rhubarb samples. Metabolomics analysis of rhubarb and stewed rhubarb indicated the various components of rhubarb changed after processing.

ABSTRACT

To study the pharmacokinetics of ginsenosides Rg1 and its metabolites after iv and oral administration in Wistar rats, the LC-MS/MS method was selected to determine ginsenosides Rg1 and its metabolites in plasma and their pharmacokinetic parameters were calculated. After oral administration of ginsenosides Rg1 to rats, ginsenosides Rg1, Rh1, F1 and protopanaxatriol (Ppt) could be detected in plasma. Their Tmax were 0.92, 3.64, 5.17, and 7.30 h, respectively; MRT were 2.68, 5.06, 6.65, and 5.33 h, respectively; AUC(o-t), were 2 363.5, 4 185.5, 3 774.3, and 396.2 ng x mL(-1) x h, respectively. After iv administration of ginsenosides Rg1 to rats, ginsenosides Rg1, Rh1 and FI could be detected in plasma. Their T1/2betaS were 3.12, 5.87, and 6.87 h, respectively; MRTs were 1.92, 5.99, and 7.13 h, respectively; AUCo-tS were 1 454.7, 597.5, and 805.6 ng x mL(-1) x h, respectively. So, it can be concluded that after oral administration, the amounts of metabolites were higher than the prototype in vivo, and the distribution and elimination of the metabolites were relatively slow. After iv administration, the amount of prototype were higher than that of the metabolites in vivo, and the distribution and elimination of the metabolites were relatively slow.
