The actual Association Between Functional Reputation and also Health-Related Quality of Life Following Discharge from your Kid Demanding Attention Product.
TUNEL staining showed that the blue-green fluorescence of the phenolic part group decreased successively, and the degree of myocardial cell apoptosis was reduced. Immunohistochemical staining suggested that it could reduce the number of positive cells for p53 protein expression and significantly improve myocardial cell damage. All above data suggested that the phenolic part group had an anti-mycardial ischemis effect. Related mechanism studies revealed that the crude phenolic part could regulate the expressions of the p53 gene(p53), Bcl-2-associated X protein(Bax), B lymphoma-2 gene(Bcl-2), and caspase-3 protein(caspase-3) in myocardial tissue, suggesting that it could reduce cardiac remodeling and myocardial ischemic damage, and improve cardiac function by inhibiting myocardial apoptosis.This research laid a foundation for the elucidation of the pharmacological ingredients R. chinensis.Schisandrae Chinensis Fructus in six growth stages was taken as materials to study the species and content changes of material basis, which were detected by UPLC, GC and MS chromatography, including lignans, nucleosides, aroma components and fatty acids. The results showed that the texture, color and taste of Schisandrae Chinensis Fructus in six growth stages were different. On the material basis, 12 lignans were detected by UPLC-MS, and the content of total lignans was higher in the samples from late August to early September, among which the highest content of schisandrin was 0.67%±0.01%, followed by schizandrol B, angeloylgomisin H and schisandrin B, and the total content increased with the maturity of Schisandrae Chinensis Fructus. Thirteen kinds of nucleosides were detected by UPLC. The total nucleoside content was the highest in late July samples, in which the contents of uridine and guanosine were higher and decreased after maturity. Aroma components and fatty acids were identified by GC-MS. A total of 53 aroma components were detected and the highest total content was appeared in late August samples, of which ylangene was higher and bergamotene was followed. A total of 24 kinds of fatty acids were detected. The fruits matured basically in August, and the content of fatty acids in the samples was the highest, among which linoleic acid content was top the list and oleic acid was the second. To sum up, the maturity of Schisandra chinensis fruit is related to the content and variety of various material bases, and the growth period has different influences on the quality of Schisandrae Chinensis Fructus. Therefore, the appropriate harvesting time should be determined according to the change law of target components. The results of this study can provide reference for the quality evaluation of Schisandrae Chinensis Fructus material basis.In this study, HPLC-ESI-MS and HPLC methods were established to explore the differences in the main chemical components and content of Mori Cortex with(mulberry root bark) and without(Mori Cortex) the phellem layer from both qualitative and quantitative aspects. The HPLC-ESI-MS method was used for quality analysis in positive and negative ion modes, and 33 compounds were identified in mulberry root bark, 22 compounds in Mori Cortex, and 26 compounds in phellem layer; mulberry root bark and Mori Cortex shared 22 components, and mulberry root bark has 11 unique compounds; Mori Cortex and its phellem layer shared 15 components, while Mori Cortex has 7 unique compounds. HPLC method was used to simultaneously determine 7 major constituents, including mulberroside A, chlorogenic acid, dihydromorin, oxyresveratrol, moracin O, kuwanon G, and kuwanon H, and the developed method showed good linearity(r>0.998 9) within the concentration range and the recoveries varied from 99.88% to 103.0%, and the RSD was 1.7%-2.9%. The HPLC results showed that the contents of the 7 compounds have great differences in 13 batches samples, compared with mulberry root bark, the contents of mulberroside A, chlorogenic acid, dihydromorin and moracin O of Mori Cortex were increased, while the contents of oxyresveratrol, kuwanon G and kuwanon H were decreased after peeling process. These results can provide a basis for the rationality and quality control of Mori Cortex required to remove the phellem layer.To establish a quantitative analysis of multi-components by single marker(QAMS) method for five flavonoids in Rhododendron anthopogonoides and verify its feasibility and applicability in the medicinal materials of R. anthopogonoides. With hyperoside as the internal reference, relative correction factors(RCF) of rutin, quercetin, quercitrin and kaempferol were established by high-performance liquid chromatography(HPLC) analysis. RCFs were used to calculate the content of each component, system durability and relative retention time. Simultaneously, QAMS and external standard method(ESM) were used to determine the content of five flavonoids in 12 batches of R. anthopogonoides from different origins. The results were statistically analyzed to verify the accuracy and feasibility. The fingerprints and cluster analysis data of R. anthopogonoides analyzed and discussed differences among the batches. learn more According to the results, the RCFs of rutin, quercetin, quercetin and kaempferol in R. anthopogonoides were 1.242 6, 0.990 5, 0.535 0, and 0.781 3, respectively. The RCFs represented a good reproducibility under different experimental conditions. Besides, there was no significant difference between QAMS and ESM. Besides, the fingerprint and cluster analysis data showed the consistency between the classification and with the origin distribution of the herbs. In conclusion, the QAMS method shows a good stability and accuracy in the quality control of R. anthopogonoides.A new method of MS/MS~(ALL) was designed to sequentially record a MS~2 spectrum at each unit mass window through gas phase fractionation concept, so as to offer an opportunity for universal MS~2 spectral recording with direct infusion(DI). As a proof-of-concept, DI-MS/MS~(ALL) was applied for rapid chemome profiling of a famous herbal medicine named Lonicerae Japonicae Flos. After each MS~2 spectrum was correlated to its precursor ion, the structural annotation was conducted by applying well-defined mass cracking rules, matching the mass spectral data with literatures and referring to those accessible databases. As a result, a total of 54 components were identified from Lonicerae Japonicae Flos extract, including 21 phenolic acids, 13 flavonoids, 12 iridoids, 4 triterpenoids and 4 other compounds. Therefore, DI-MS/MS~(ALL) is a powerful tool for comprehensive, rapid qualitative analysis of chemical profiles of traditional Chinese medicine and other chemical components of complex systems.
