RESUMEN
Slicing is critical in the processing of Chinese materia medica(CMM) processed product and the specification(thickness) is closely related to the quality of the decoction. On the basis of clarifying the concept and evolution of slicing of CMM processed product by reviewing the Chinese herbal classics of the past dynasties and general rules of local processing standards, this study discussed the development history of slicing specifications in general rules of Chinese Pharmacopoeia(2020 edition), analyzed the current situation and key problems, and proposed the thinking and suggestion on promoting the sound development of slicing of CMM processed product. Since 2000, the slicing thickness of CMM processed product in the general rules of local CMM processed product processing specifications newly revised and issued by 27 provinces, autonomous regions, and municipalities has been consistent with that in the general rules of the Chinese Pharmacopoeia(2020 edition). The standard that the thickness of extremely thin pieces is less than 0.5 mm is rarely retained, and the pieces in 0.5-1 mm thickness have not been found on the market, which is consistent with the provisions of the general rules of the Chinese Pharmacopoeia. This study can provide a historical and modern basis for the rationality of slicing of CMM processed product.

This study aims to reveal the effects of different growth patterns and years on the quality of Saposhnikoviae Radix samples. The apparent colors of the powder samples were quantified by a colorimeter, and the total color values(E~*ab) were calculated. The content of prim-O-glucosylcimifugin, cimifugin, 4'-O-ß-D-glucosyl-5-O-methylvisamminol, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol in the samples was simultaneously determined by high performance liquid chromatography(HPLC). Cluster analysis, principal component analysis, partial least squares discriminant analysis, and Pearson correlation analysis were performed to analyze the powder chromatic values and the content of 5 components. The results showed that the E~*ab values of the samples were in the order of wild group<multiple-year-old group<one-year-old group. The content of cimifugin, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol in the wild group was significantly higher than that in the multiple-year-old and one-year-old groups. The results of multivariate statistical analysis showed that the quality of multiple-year-old group varied greatly. The quality of the multiple-year-old samples was close to that of the wild group and better than that of the one-year-old group. The variable importance in the projection(VIP) values of b~*, 3'-O-angeloylhamaudol content, E~*ab, and L~* were all larger than 1, and that of cimifugin content was close to 1. The E~*ab value was negatively correlated with the content of prim-O-glucosylcimifugin, cimifugin, sec-O-glucosylhamaudol, and 3'-O-angeloylhamaudol, while it had no linear correlation with the 4'-O-ß-D-glucosyl-5-O-methylvisamminol content. The growth patterns and years had different effects on the quality of Saposhnikoviae Radix samples. The chromatic values of Saposhnikoviae Radix and the content of 5 components can be used to evaluate the quality of Saposhnikoviae Radix, and 3'-O-angeloylhamaudol and cinmifugin can be considered as markers for the quality control of Saposhnikovia divaricata during the growing process.

Hepatic disorders are a serious health problem threatening human beings. Cuscutae semen (CS), a widely used Chinese medicine, is a tonic to nourish the liver and kidney. Our research aimed to assess the hepatoprotective effect of CS on CCl4 -induced liver injury rats using plasma metabolomics. Liver injury in rats was induced by 40% CCl4 in olive oil twice a week for 21 days. The CS group received 2 g/kg of CS every day for 21 days. The liver tissues were used for histological studies. The serum was used for the analysis of biochemical parameters. Plasma metabolomic analysis was performed using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. CS could relieve hepatocyte necrosis and decrease the levels of serum biochemical parameters in comparison the with CCl4 group. Principal component analysis and orthogonal partial least squares-discriminant analysis on plasma metabolomes showed an obvious separation among the control, model, and CS groups. Heatmap showed that CS-administered mice had similar metabolite profiles as the control group. Seven influential pathways in plasma of the hepatoprotective effect impacted by CS were identified. This study confirmed the hepatoprotective effect of CS, and the related metabolic pathways were discussed.

As the last procedure of traditional Chinese medicine(TCM) applied in clinical practice, prescription-based processing(PBP) is an important guarantee for the quality and clinical efficacy of TCM, which can not only maximize the effect of processed product, but also exert the characteristics of syndrome differentiation and treatment in TCM. However, due to various reasons, most medical institutions have no PBP business. As a result, doctors can only use the conventional decoction pieces available on the market, which also greatly limits their flexible medication, with certain impacts on the normal development of the curative effect of TCM. Therefore, the article explained the necessity of PBP from three aspects. In addition, according to Chinese Pharmacopoeia and the characte-ristics of TCM decoction pieces, the varieties suitable for PBP were summarized and proposed, and also some suggestions about developing PBP are given. The PBP is one of the characteristic techniques in TCM, with special technical requirements and profound scientific connotation. The development of PBP will not only promote the processing of TCM and ensure the clinical efficacy, but also promote the vigorous development of TCM.

Thin layer chromatography, high performance liquid chromatography and multivariate statistical analysis were integrated in current study to provide a basis for the quality evaluation and the standard improvement of Paridis Rhizoma(Chinese name: Chong-lou). The results demonstrated that the primary saponins in the two authorized sources of Paridis Rhizoma were polyphyllinsâ , â ¡ and â ¦, while the rhizome of Trillium tschonoskii an adulterant of Paridis Rhizoma was rich of polyphyllin â ¥. Therefore, the apparent content of polyphyllin â ¥ plays a determinant role towards the source authentication of raw materials and decoction slices of Paridis Rhizoma, whose adulterants frequently occur in the market. Moreover, the contents of polyphyllin â ¥ in the two authorized sources could meet the requirements of Chinese Pharmacopoeia. Therefore, we suggested that polyphyllin â ¥ should not be omitted from the quality standard of Paridis Rhizoma in the Chinese Pharmacopoeia, and on the other side, polyphyllinsâ , â ¡ and â ¦ should be the eligible quality indicators. The study aims to sound information and evidences for the quality evaluation of Paridis Rhizoma, and also to provide a theoretical basis for the standard revision of Paridis Rhizoma in the future Chinese Pharmacopoeia.

BACKGROUND: The kidney plays a central role in elimination of metabolic waste products and regulation of low-molecular weight metabolites via glomerular filtration, tubular secretion and reabsorption. Disruption of these processes results in profound changes in the biochemical milieu of the body fluids, which contribute to complications of chronic kidney disease (CKD) by inducing cytotoxicity and inflammation. Insight into the changes of the composition of metabolites and dysregulation of target genes and proteins enhances the understanding of the pathophysiology of CKD and its complications, and the development of novel therapeutic strategies. Chronic interstitial nephropathy is a common cause of CKD. The present study was designed to determine the effect of chronic interstitial nephropathy on the composition of serum metabolites and regulation of oxidative, inflammatory, fibrotic and cytoprotective pathways. METHODS: Male Sprague-Dawley rats were randomized to the CKD and control groups ( n = 8/group). CKD was induced by administration of adenine (200 mg/kg body weight/day) by oral gavage for 3 weeks. The control group was treated with the vehicle alone. The animals were then observed for an additional 3 weeks, at which point they were sacrificed and kidney and serum samples were collected. Serum metabolomic and lipidomic analyses were performed using ultra-performance liquid chromatography-quadrupole time-of-flight high-definition mass spectrometry. Kidney tissues were processed for histological and molecular biochemical analyses. RESULTS: CKD rats exhibited increased plasma urea and creatinine concentrations, renal interstitial fibrosis, tubular damage and up-regulation of pro-inflammatory, pro-oxidant and pro-fibrotic pathways. Comparison of serum from CKD and control rats revealed significant differences in concentrations of amino acids and lipids including 33 metabolites and 35 lipid species. This was associated with marked abnormalities of fatty acid oxidation, and γ-linolenic acid and linoleic acid metabolism in CKD rats. Logistic regression analysis identified tetracosanoic acid, docosatrienoic acid, PC(18:3/14:1) and l -aspartic acid, tetracosanoic acid and docosatrienoic acid as novel biomarkers of chronic interstitial nephropathy. CONCLUSIONS: Advanced CKD in rats with adenine-induced chronic interstitial nephropathy results in profound changes in the serum metabolome, activation of inflammatory, oxidative and fibrotic pathways, and suppression of cytoprotective and antioxidant pathways.

In traditional Chinese medicine practice, drying method is an essential factor to influence the components of Chinese medicinal herbs. In this study, an ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UPLC-QTOF-MS/MS)-based approach was used to compare the content of chemical compounds of mountain cultivated ginseng that had been natural air dried (LX-P) and vacuum freeze-dried (LX-L). Multivariate statistical analysis such as principal component analysis (PCA) and supervised orthogonal partial least squared discrimination analysis (OPLS-DA) were used to select the influential components of different samples. There were 41 ginsenosides unambiguously identified and tentatively assigned in both LX-L and LX-P. The results showed that the characteristic components in LX-P were ginsenoside Rb1, ginsenoside Rc, ginsenoside Rg6, dendrolasin, and ginsenoside Rb2. The characteristic components in LX-L were malonyl-ginsenoside Re, malonyl-ginsenoside Rb1, malonyl-ginsenoside Rc, malonyl-ginsenoside Rb1 isomer, malonyl-ginsenoside Rb2, malonyl-ginsenoside Rb3, malonyl-ginsenoside Rd isomer, gypenoside XVII, and notoginsenoside Fe. This is the first time that the differences between LX-L and LX-P have been observed systematically at the chemistry level. It was indicated that vacuum freeze-drying method can improve the content of malonyl-ginsensides in mountain cultivated ginseng.

The fluoritum is used for gynecology frequently and it's for those diseases: kidney yang deficiency, Gong cold sterility, palpitation due to fright, insomnia and dreaminess and cold cough. It's ruled in Chinese Pharmacopoeia (1985 edition) that the fluoritum originates from fluorite which belongs to fluoride minerals. Its main content is CaF2. The colors are of differents grades with purple or green. In the market, there are large differences in quality and it has various colors. Besides of the ruled color of purple and green, white and yellow are also common colors. By digging into and analysis the relevant research literature of fluorite which belongs to fluoride minerals, colors and coloration mechanism of fluorite are summarized in this paper.Natural fluorite is the mineral which has the most species of colors in nature. The different colors of fluorite are mainly caused by the impurity elements. At present, there are mainly about the coloration mechanism of fluorite: rare earth ions (4fN ions), color center, inclusions, crystalline domains or sub microscopic inclusions. The green of fluorite is produced by 570 nm and 305 nm absorption peaks which are caused by Sm2+ and compensated ions Na+ centers generated color center. The yellow of fluorite is produced by the joining of transition element, resulting in the formation of charge transfer between the crystal ions and the formation of O2-O32- ion molecule.The black of fluorite, mainly was attributed to the existence of a higher degree of evolution of organic matter. In this passage,suggestions for modification of the properties of fluoritum in Chinese Pharmacopoeia are put forward.

Fourier transform infrared (FTIR) microspectroscopy technology is the combination of the FTIR spectrometer and the microscope. This technology is of simple preparation of the samples, can be used in micro-area analysis and micro-samples, and reflect the nature of the samples spectra. Panax ginseng include mountain cultivated ginseng (MCG), garden cultivated ginseng (GCG) and mountain wild ginseng (MWG), but the excavation of MWG is prohibited in China. So, only MCG and GCG were collected and recorded in Chinese pharmacopoeia. In this study, we developed a discriminant analysis (DA) method for recognition of MCG and GCG using FTIR microspectroscopy technology. Twenty MCG samples and twenty four GCG samples were obtained, and their spectra of IR microspectroscopy were collected. Then 33 samples were randomly selected into calibration set and the remaining 11 of the samples were selected into validation set. The authors optimized the pretreatment method, the principal components, the modeling region and the scanning parts when developing the models. The optimized model of discriminant analysis was developed using the pretreatment multiplicative scatter correction (MSC) + Savitzky-Golay filter (SG) smoothing, the region 3 932.14-669.18 cm(-1), 4 principal components and the rhizome part. The accuracy of the optimized model got up to 100%. The result demonstrated that infrared microspectroscopy technology combined with DA is of simple operation, rapid, nondestructive and effective, and can be applied to recognize MCG and GCG.

Background: Alzheimer's Disease (AD) and Type 2 Diabetes Mellitus (DM) have an increased incidence in modern society. Although more and more evidence has supported that DM is prone to AD, the interrelational mechanisms remain fully elucidated. Purpose: The primary purpose of this study is to explore the shared pathophysiological mechanisms of AD and DM. Methods: Download the expression matrix of AD and DM from the Gene Expression Omnibus (GEO) database with sequence numbers GSE97760 and GSE95849, respectively. The common differentially expressed genes (DEGs) were identified by limma package analysis. Then we analyzed the six kinds of module analysis: gene functional annotation, protein-protein interaction (PPI) network, potential drug screening, immune cell infiltration, hub genes identification and validation, and prediction of transcription factors (TFs). Results: The subsequent analyses included 339 common DEGs, and the importance of immunity, hormone, cytokines, neurotransmitters, and insulin in these diseases was underscored by functional analysis. In addition, serotonergic synapse, ovarian steroidogenesis, estrogen signaling pathway, and regulation of lipolysis are closely related to both. DEGs were input into the CMap database to screen small molecule compounds with the potential to reverse AD and DM pathological functions. L-690488, exemestane, and BMS-345541 ranked top three among the screened small molecule compounds. Finally, 10 essential hub genes were identified using cytoHubba, including PTGS2, RAB10, LRRK2, SOS1, EEA1, NF1, RAB14, ADCY5, RAPGEF3, and PRKACG. For the characteristic Aß and Tau pathology of AD, RAPGEF3 was associated significantly positively with AD and NF1 significantly negatively with AD. In addition, we also found ADCY5 and NF1 significant correlations with DM phenotypes. Other datasets verified that NF1, RAB14, ADCY5, and RAPGEF3 could be used as key markers of DM complicated with AD. Meanwhile, the immune cell infiltration score reflects the different cellular immune microenvironments of the two diseases. Conclusion: The common pathogenesis of AD and DM was revealed in our research. These common pathways and hub genes directions for further exploration of the pathogenesis or treatment of these two diseases.

Background: Yiqi Huoxue Decoction (YQHXD) is a traditional Chinese medicine that promotes blood circulation, removes blood stasis, facilitates diuresis, and alleviates edema. It is composed of 10 herbal medicines and has extensive application in treating nephrotic syndrome (NS). However, the active components and the potential mechanism of YQHXD for treating NS remain unclear. Methods: We set up a sensitive and rapid method based on Ultra-High Performance Liquid Chromatograph-Mass (UPLC-MS) to identify the compounds in YQHXD and constituents absorbed into the blood. Disease genes were collected through GeneCards, DisGeNET, and OMIM database. Genes of compounds absorbed into blood were predicted by the TCMSP database. We constructed Disease-Drug-Ingredient-Gene (DDIG) network using Cytoscape, established a Protein-protein interaction (PPI) network using String, Gene biological process (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis was performed using DAVID. Cellular experiments were performed to validate the results of network pharmacology. Result: A total of 233 compounds in YQHXD and 50 constituents absorbed into the blood of rats were identified. The 36 core targets in the PPI network were clustered in the phosphatidylinositol 3 kinase-RAC serine/threonine-protein kinase (PI3K-AKT) and nuclear factor kappa-B (NF-κB) signaling pathways. Luteolin, Wogonin, Formononetin, and Calycosin were top-ranking components as potentially active compounds. Conclusion: The results of our studies show that YQHXD is able to enhance renal function, alleviate podocyte injury, and improve adriamycin nephrotic syndrome.
RESUMEN
Ginseng has been widely applied in clinical practice, but the cultivation age cannot be ignored as it influences the quality of ginseng and its products. In this work, different cultivation ages of fresh ginseng (FG) from four to seven years were analysed by UPLC-Q-TOF-MS/MS. Principal component analysis and supervised orthogonal partial least squared discrimination analysis, which belong to the normal method of multivariate statistical analysis, were applied to discover the characteristic components of FG at different cultivation ages. The components of new type of red ginseng (NRG) derived from FG at different cultivation ages were compared by HPLC analysis. The pharmacological anti-inflammatory activity was evaluated by ELISA and qPCR. The result showed that the characteristic components of both 6- and 7-year-old ginseng were ginsenoside Rb1, mal-ginsenoside Rb1, ginsenoside Rc, mal-ginsenoside Rc, mal-ginsenoside Rb1 isomer, and mal-ginsenoside Rb2. Moreover, the characteristic components of both 4- and 5-year-old ginseng were ADP-glucose and 3-hydroxyhexanoyl CoA. In addition, 6-year-old NRG has higher rare ginsenosides than 4-year-old NRG, which possesses great anti-inflammatory activity in vitro. The results reveal the ginsenoside transformation law of NRG processing and suggest that the cultivation age of FG influences the content of ginsenosides in NRG. Therefore, 6-year-old ginseng is more suitable for red ginseng processing and clinical use.
