Comprehensive data, including the information on the four TCM diagnoses, general data, and blood biochemical indicators of participants in both groups, were collected separately for analysis. The differentiation principles of syndrome elements were used to discern the location and nature of hypertension. One-way analysis was carried out to screen for potential risk factors of the disease. Least absolute shrinkage and selection operator (LASSO) regression was used to identify factors that contribute significantly to the model, and eliminate possible collinearity problems. At last, multivariate logistic regression analysis was used to both screen and quantify independent risk factors essential for the prediction model. The “rms” package in the R Studio was used to construct the Nomogram model, creating line segments of varying lengths based on the contribution of each risk factor to aid in the prediction of risks of hypertension. For internal model validation, the Bootstrap program package was utilized to perform 1000 repetitions of sampling and generate calibration curves.</p></div><div><h3>[Results]</h3><p>The results of the multivariate logistic regression analysis revealed that the risk factors of EH included age, heart rate (HR), waist-to-hip ratio (WHR), uric acid (UA) levels, family medical history, sleep patterns (early awakening and light sleep), water intake, and psychological traits (depression and anger). Additionally, TCM syndrome elements such as phlegm, Yin deficiency, and Yang hyperactivity contributed to the risk of EH onset as well. TCM syndrome elements liver, spleen, and kidney were also considered the risk factors of EH. Next, the Nomogram model was constructed using the aforementioned 14 risk predictors, with an area under the curve (AUC) of 0.868 and a 95% confidence interval (CI) ranging from 0.840 to 0.895. The diagnostic sensitivity and specificity were found to be 80.7% and 85.0%, respectively.

While ZR and CZR obviously stem from the same botanical source, their attributes, chemical compositions, pharmacological behaviors, and clinical applications are different owing to variations in the extent of drying and processing they undergo. In this paper, data pertaining to ZR and CZR were retrieved from databases including China National Knowledge Infrastructure (CNKI), PubMed, Web of Science, and Google Scholar. These sources were scrutinized to elucidate the distinctions between ZR and CZR arising from carbonization processing in terms of their ethnopharmacology, quality control, chemical compositions, biological activities, pharmacological mechanisms, and clinical uses. In this study, a total of 56 chemical constituents were identified and isolated from ZR and CZR, which primarily encompassed volatile oils, gingerols, and diphenylheptane compounds. CZR's pharmacological effects include hemostatic, anti-oxidant, analgesic, antibacterial, anti-cancer, and other biological activities. ZR has pungent and warm properties. It is a Yang-supplementing herbal medicine for ailments exacerbated by cold or damp climatic influences. CZR is a product of ZR after undergoing high temperature, with diminished intensity of its pungent and warm attributes. This change leads to a more gradual treatment efficacy, renowned hemostatic effects and its ability to gently invigorate the spleen and effectively alleviate diarrhea. Currently, research on the pharmacological mechanism of CZR is mainly focused on the effects of CZR on coagulation and fibrinolysis. Although the healing effect of CZR has long been known, and some correlation has been found between the changing composition and the changing color of the decoctions, people still lack relatively clear processing mechanisms to reflect the characteristics and specific quality standards of the ingredients of CZR's hemostatic effect. This review provides a systematic summary on quality control, chemical composition, ethnopharmacology, and pharmacology of CZR, offering novel perspectives for advancing the exploration of additional carbonized herbal medicine and fostering their application in clinical settings.</p></div>","PeriodicalId":33578,"journal":{"name":"Digital Chinese Medicine","volume":"6 3","pages":"Pages 341-356"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589377723000599/pdfft?md5=240a119c27f4076e0379025406642fa3&pid=1-s2.0-S2589377723000599-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138395701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Next, utilizing the outcomes of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, the biological processes and signaling pathways in which ginsenosides predominately engaged were scrutinized, and the primary targets of ginsenosides in combating weightlessness-induced inflammation were examined. Finally, enzyme-linked immunosorbent assay (ELISA) was performed to detect the secretion levels of interleukin (IL)-1<em>β</em>, IL-6, IL-8, and tumor necrosis factor (TNF)-<em>α</em> from lipopolysaccharide (LPS)-induced THP-1 cells under simulated weightlessness conditions, as well as during the weightlessness recovery period following treatment with ginsenosides.</p></div><div><h3>Results</h3><p>A total of 2 933 genes associated with inflammation, 425 genes linked to weightlessness, and 4 564 genes connected to immunity were retrieved from the GeneCards database.

And the 661W cells were exposed to varying concentrations of H₂O₂ ranging from 50 to 400 μmol/L to determine the optimal concentration for inducing apoptosis (200 μmol/L). Then the cell viability was assessed using Cell Counting Kit-8 (CCK-8), while the apoptosis rate was detected by flow cytometry; the expression of NLRP3 was detected by immunofluorescence; and the expression of apoptosis markers was detected by enzyme-linked immunosorbent assay (ELISA) and Western blot (WB).

The drugs were used a total of 3 901 times, and a total of 10 915 cases were collected, among which the prevalence rate was higher in males. The main types of TCM syndrome included intermingled phlegm and blood stasis syndrome, liver depression and spleen deficiency syndrome, and damp-heat in liver and gallbladder syndrome, among which Shanzha (Crataegi Fructus), Danshen (Salviae Miltiorrhizae Radix et Rhizoma), Fuling (Poria), Zexie (Alismatis Rhizoma), Chaihu (Bupleuri Radix), and Baizhu (Atractylodis Macrocephalae Rhizoma) were the most frequently used. The properties of Chinese medicine primarily encompassed thermal characteristics, with a predominant emphasis on cold and warm; the flavors of herbs were predominantly characterized by bitterness and sweetness, while the majority exhibited tropism towards the spleen and liver meridians. The drugs were primarily classified based on their efficacy in tonifying deficiencies, promoting diuresis and moistening, enhancing blood circulation and removing blood stasis, heat-clearing, etc. The association rules were employed to derive a set of 20 core drug pairs, while cluster analysis was utilized to identify three distinct groups of core drug combinations. Network pharmacological showed that the main components of the core formula “Shanzha (Crataegi Fructus) - Danshen (Salviae Miltiorrhizae Radix et Rhizoma) - Zexie (Alismatis Rhizoma) - Chaihu (Bupleuri Radix) - Fuling (Poria)” in the treatment of MAFLD were quercetin, apigenin, puerarin, luteolin, ursolic acid, kaempferol, tanshinone IIA, emodin, paeonol, etc., which involved RAC-alpha serine/threonine-protein kinase 1 (AKT1), cellular tumor antigen p53 (TP53), interleukin (IL)-6, IL-1<em>β</em>, signal transducer and ","PeriodicalId":33578,"journal":{"name":"Digital Chinese Medicine","volume":"6 3","pages":"Pages 257-271"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589377723000526/pdfft?md5=206c27be40ee42f6346f7000f05c688b&pid=1-s2.0-S2589377723000526-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138390011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
