[Objective] To construct a Nomogram model for the prediction of essential hypertension (EH)
risks with the use of traditional Chinese medicine (TCM) syndrome elements principles in
conjunction with cutting-edge biochemical detection technologies.
[Methods] A case-control study was conducted, involving 301 patients with essential hypertension in the hypertensive group and 314 without in the control group. 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.
[Results] 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. Internal validation confirmed the model’s robust predictive performance, with aconsistency index (C-index) of 0.879, underscoring the model’s strong predictive ability.
[Conclusion] By integrating TCM syndrome elements, the Nomogram model has realized the objective, qualitative, and quantitative selection of early warning factors for developing EH, resulting in the creation of a more comprehensive and precise prediction model for EH risks.

[Objective[ To analyze the main syndrome types, medication rules, and core prescription
characteristics of traditional Chinese medicine (TCM) in the treatment of metabolism-associated fatty liver disease (MAFLD), and to predict the anti-MAFLD mechanism of core formula, so as to provide references for the clinical application of TCM and the development of new drugs.
[Methods] Literature research on TCM in treating MAFLD was retrieved from China National
Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP),
and Wanfang Database since the establishment of the database to July 2022. Excel 2019 and
Chinese Medicine Inheritance Computing Platform (V3.0) were used for frequency analysis,
association rule analysis, and cluster analysis of effective prescriptions. The key components,
targets, and action pathways of anti-MAFLD core formulas were predicted by network pharmacology. Finally, the interactions between the obtained core components and their core targets were verified reversely by molecular docking technology.
[Results] A total of 218 articles were screened and selected, including 352 prescriptions, involving 270 traditional Chinese herbs. 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 stasisheat-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-1β, signal transducer and activator of transcription 3 (STAT3), epidermal growth factor receptor (EGFR), peroxisome proliferative activated receptor gamma (PPARG), and other key targets. The molecular docking results showed that the core components had good binding to lipid and atherosclerosis, and phosphatidylinositol 3 kinase (PI3K)/AKT signaling pathway-associated proteins.
[Conclusion] The main principles of TCM for the treatment of MAFLD involve soothing the liver and strengthening the spleen, eliminating phlegm and dampness, clearing heat and dampness, as well as promoting blood circulation and removing blood stasis. The core formula may exert anti-MAFLD effects mediated through multiple components, targets, and signaling pathways. This study establishes a theoretical foundation for the clinical application of TCM in the treatment of MAFLD, and serves as a reference for further exploration of new drugs against MAFLD.

[Objective] To explore the application of Quality by Design (QbD) tools in assessing geographical variations of Phyllanthus emblica (P. emblica) from five distinct Indian states.
[Methods] In the current experiment, the Box-Behnken design with a reduced quartic model and 105 runs was employed with the use of the Design Expert software for randomized response surface mapping. Three different extraction methods (Soxhlet, maceration, and sonication) along with three solventst [distilled water, methanol, and water-methanol mixture (50 : 50 v/v)] were considered in the present study. The anti-oxidant activities, total flavonoid content (TFC), and total phenolic content (TPC) in the P. emblica were determined and analysed by gas chromatography-mass spectrometry (GC-MS) to identify the major components.
[Results] The QbD overlay plot showed that the extractive value of the P. emblica was no less than 30% w/w, 2,2-diphenyl-1-picrylhydrazyl (DPPH) no less than 60% mcg/mL (micrograms per millilitre), TFC no less than 75 mg QE/g (milligrams of quercetin equivalents per gram), and TPC no less than 80 mg GAE/g (milligrams of gallic acid equivalents per gram). Moreover, the GC-MS data confirmed the presence of variation in the bioactives of P. emblica extracts.
[Conclusion] The model was significant in describing the variation in extractive value, DPPH, TFC, and TPC. The QbD approach may tend to prioritize thoroughness in the extraction process, ultimately resulting in improved quality in the extracted products.

[Objective] To investigate the evolution of inflammation under conditions and the effects of ginsenosides on macrophages subjected to the simulated weightlessness, with the aim of mitigating the inflammation.
[Methods] Initially, genes related to weightlessness, inflammation, and immunity were identified in the GeneCards database. Then, Search Tool for the Retrieval of Interaction Gene/Proteins (STRING) protein network analysis was conducted to determine the core targets involved in the weightlessness-induced inflammation. Subsequently, Label-Free Quantitative
(LFQ) proteomics was carried out to discern the distinctive genes within ginsenoside-treated
Tohoku Hospital Pediatrics-1 (THP-1) cells. 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)-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α from lipopolysaccharide (LPS)-induced THP-1 cells under simulated weightlessness conditions, as well as during the weightlessness recovery period following treatment with
ginsenosides.
[Results] 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. Protein-protein interaction (PPI) networks were generated to identify pivotal targets associated with weightlessness-induced inflammation such as IL-1β, IL-6, TNF, and albumin (ALB). It was found that ginsenosides primarily participated in the regulation of various inflammationrelated signaling pathways and pathways related to pathogenic microorganism infections. Moreover, it has a significant impact on the expression of proteins such as cluster of differentiation 40 (CD40), IL-1β, and poly ADP-ribose polymerase 1 (PARP1). As revealed in the simulated weightlessness cell test, ginsenosides exhibited a remarkable capacity to attenuate the secretion of inflammatory factors, specifically IL-6 and TNF-α (P < 0.000 1), in THP-1 macrophages following induction by LPS under simulated weightlessness conditions. In addition, it reduced the secretion of IL-1β, IL-6, IL-8, and TNF-α (P < 0.000 1) during the weightlessness recovery phase
[Conclusion] Weightlessness can disrupt several inflammation-related signaling pathways, but ginsenosides were shown to mitigate the release of various inflammatory factors in macrophages subjected to simulated weightlessness, thereby exerting a protective role against inflammation. This study has laid a theoretical groundwork for further exploring the potential application of ginsenosides in safeguarding against LPS induced inflammation in a weightlessness environment.

Objective:
To evaluate the methodological quality of papers that performed meta-analyzed and systematically reviewed acupoint selections for the treatment of functional dyspepsia (FD) and to identify the ideal acupoint combinations for FD.
Methods:
Chinese databases including China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), China Biology Medicine (CBM), and Wanfang Database, as well as English databases including PubMed, Embase, and Cochrane Library were searched to retrieve papers about meta-analysis and systematic literature reviews on acupuncture for FD. The time span for the paper retrieval was set from the foundation of the databases to April 30, 2022. The Veritas scores of the papers based on their publication year, study type, Assessment of Multiple Systematic Reviews 2 (AMSTAR2), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), heterogeneity, and publication bias were rated to assess the methodological quality of the included studies. Then, randomized controlled trials (RCTs) were extracted from those meta-analysis papers or systematic literature reviews for analyzing acupoints frequency, meridian frequency, and association rules with the use of R software (V 4.3.1).
Results:
Eight meta-analysis papers were included in the study after screening. The mean Veritas scores of the papers based on publication year, type of study, AMSTAR2, PRISMA, heterogeneity, and publication bias were 4.50, 8.00, 4.63, 4.63, 4.50, and 6.13, respectively. The analysis of the scores revealed insufficiencies in the reviews pertaining to the methodology, comprehension of the research strategy, detailed list of excluded studies, sources of funding, assessment of potential bias risks impact on meta-analysis results in each study, explanation of heterogeneity, and identification of potential conflicts of interest. Furthermore, a total of 85 RCTs were obtained from the eight meta-analysis papers involving 85 acupuncture prescriptions and 67 acupoints for subsequent data mining. The most commonly used meridian was Stomach meridian of Foot-Yangming (ST). Zusanli (ST36), Neiguan (PC6), Zhongwan (CV12), Taichong (LR3), Tianshu (ST25), Gongsun (SP4), Weishu (BL21), Pishu (BL20), Neiting (ST44), and Yinlingquan (SP9) topped the list of frequently selected acupoints. Additionally, a total of 28 association rules were identified, including 10 second-order, 15 third-order, and 3 fourth-order association rules. The top-ranking association rules in each order were “Neiguan (PC6) → Zusanli (ST36)” “Zhongwan (CV12) + Neiguan (PC6) → Zusanli (ST36)” and “Zhongwan (CV12) + Taichong (LR3) + Neiguan (PC6) → Zusanli (ST36)”, respectively.
Conclusion
Acupuncture could alleviate the clinical symptoms of FD. However, the quality of methodology applied in the meta-analysis papers on the subject needs to be improved. Through data mining, a combination of Neiguan (PC6), Zusanli (ST36), Zhongwan (CV12), and Taichong (LR3) was identified as an essential acupoint combination for the treatment of FD.

Objective:
To investigate the cardioprotective effect of Saffron (Crocus sativus L.) treatment as
a potential supplement on patients with type 2 diabetes mellitus (T2DM).
Methods:
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied to analyze articles retrieved from PubMed, ScienceDirect, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and China Biology Medicine (CBM) with a publication time span from January 15, 2015 to March 20, 2023. The articles were published in English only, including randomized controlled trials (RCTs) on adult patients who were diagnosed with T2DM, and received either Saffron or placebo treatment. Meta-analysis was performed using Review Manager 5.4 software. The present study was registered on the International Prospective Register of Systematic Reviews (PROSPERO) with a registration number as CRD42023443180.
Results:
Seven RCTs with 455 patients were included in the study. The data revealed that Saffron treatment significantly reduced tumor necrosis factor (TNF)-α (P = 0.008) and fasting blood glucose (FBG) (P = 0.04) levels compared with what placebo did in T2DM patients. No significant differences were shown in the levels of interleukin (IL)-6, malondialdehyde (MDA), high serum C-reactive protein (hs-CRP), lipid profile, blood pressure, and body mass index (BMI) between Saffron and placebo ( P > 0.05) .
Conclusion
Saffron treatment has a cardioprotective effect in T2DM patients by reducing TNF-α and FBG levels. However, the potential anti-oxidant, anti-hypertensive, and anti-dyslipidaemia effects of the phytochemical need to be further investigated.

Objective:
To explore the therapeutic effects of ginseng total saponins (GTSs) on cognitive impairments in astronauts caused by prolonged exposure to microgravity environment.
Methods:
Fifty specific pathogen-free (SPF) male Wistar rats were randomized into control, hindlimb suspension (HLS), Huperzine A (HLS-Hup A 0.1 mg/kg), low-dose GTSs (HLS-GTSs 100 mg/kg), and high-dose GTSs (HLS-GTSs 200 mg/kg) groups, based on the completion time of reward-directed conditioning tasks. Except for rats in the control group, the others were subjected to HLS and treated with drugs (day 20 – 58), received reflex test under the condition of rewarding, and underwent Nissl body staining and Western blot detection on hippocampal.
Results:
After modeling, rats in HLS group exhibited a reduction in the number of lever presses and an increase in the completion time of the reward-directed operant conditioning task Ⅰ (P < 0.05) when compared with the control group, which were not substantially altered in the HLS-GTSs 100 and 200 mg/kg groups (P > 0.05). In the reward-directed operant conditioning task Ⅱ, the HLS group rats demonstrated a marked decrease in the number of lever presses (P < 0.05) and nose pokes (P < 0.01) when compared with the control group rats; the HLS-GTSs 100 mg/kg showed a significant increase in the number of lever presses and nose pokes (P < 0.05), while the HLS-GTSs 200 mg/kg demonstrated a significant reduction in completion time and an elevation in the number of lever presses (P < 0.05) when compared with the HLS group rats. In visual signal discrimination task, compared with the control group rats, the HLS group rats showed decrease in the indexes of the visual signal discrimination(P < 0.01), while HLS-GTSs 100 and 200 mg/kg groups exhibited manifest increase in it (P < 0.01). In reward extinction experiment, the number of lever presses in HLS rats significantly increased when compared with the control group (P < 0.01); compared with the HLS group,
HLS-GTSs 100 and 200 mg/kg groups demonstrated a marked descrease (P < 0.05). The expressions of N-methyl-D-aspartic acid receptor 1 (NR1) and phosophorylated N-methyl-Daspartic acid receptor 2B (p-NR2B) proteins were markedly decreased in rats in the HLS group (P < 0.05 and P < 0.01, respectively), while that of NR2B protein maintained the same (P > 0.05). GTSs increased the expression levels of p-NR2B (P < 0.01).
Conclusion
GTSs improved the learning and memory ability of complex operations by regulating the NR1/NR2B phosphorylation pathways in rats.
