ObjectiveThis paper aims to study the potential active compound components and action mechanism of Shenqi Dihuangtang in the treatment of diabetic kidney disease (DKD) through network pharmacology and in vivo experimental verification. MethodsUltra-high-performance liquid chromatography-Q-exactive orbitrap mass spectrometry (UPLC-Q-Exactive Orbitrap MS) technology was used to clarify the main active chemical components of Shenqi Dihuangtang, and it was combined with network pharmacology methods such as gene ontology (GO) functional annotations and Kyoto encyclopedia of genes and genome (KEGG) to predict the potential action mechanism of Shenqi Dihuangtang in treating DKD. Subsequently, the DKD model of db/db male mice was established, and the mice were randomly divided into model group, low-dose Shenqi Dihuangtang group (6.10 g·kg-1), medium-dose Shenqi Dihuangtang group (12.19 g·kg-1), high-dose Shenqi Dihuangtang group (24.38 g·kg-1), and daplizin group (1.25 mg·kg-1). During the same period, C57BL/6J male mice were selected into normal group and received drug intervention for 8 weeks, respectively. During this period, the body weight and fasting blood glucose (FBG) of the mice were dynamically monitored, and oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed at the end of dosing. The levels of serum creatinine (SCr), blood urea nitrogen (BUN), uric acid (UA), albumin (ALB), and total protein (TP) were measured by an automatic biochemical analyzer, and 24-hour urine protein was measured by a urine protein quantitative kit. Hematoxylin-eosin (HE), periodic-acid Schiff (PAS), and Masson staining were employed to observe the renal histopathology. The expression of nephrotic protein Nephrin was observed by immunohistochemistry. Western blot was used to detect the expression of epithelial-mesenchymal transition (EMT)-related proteins such as TGF-β1, Smad2/3, α-smooth muscle actin (α-SMA), neural-cadherin (N-Cadherin), and snail protein. ResultsUPLC-Q-Exactive Orbitrap MS identified 384 active compounds in the aqueous extract of Shenqi Dihuangtang. According to oral bioavailability≥30% and the five drug-like principles, 44 key active ingredients were screened out, and 169 intersection targets highly correlated with DKD were matched. Among them, there was a significant interaction relationship between tumor necrosis factor(TNF), interleukin(IL)-6, protein kinase B(Akt)1, Caspase-3, Jun proto-oncogene (JUN), hypoxia inducible factor-1α(HIF-1α), B cell lymphoma-2(Bcl-2), matrix metallopeptidase-9(MMP-9), IL-1β, and TGF-β1. GO functional annotations were significantly enriched in cellular components such as membrane rafts, membrane microdomains, and collagen-containing extracellular matrix, molecular functions such as DNA-binding transcription factor binding, R-Smad binding, and Smad protein binding, as well as biological processes such as reactions to lipopolysaccharides(LPS), reactions to bacteria-derived molecules, and wound healing. The KEGG pathway was significantly enriched in lipids and atherosclerosis, TGF-β signaling pathway, phosphatidylinositol 3 kinase (PI3K)/Akt signaling pathway, etc. In vivo experimental results showed that the high-dose Shenqi Dihuangtang group could significantly reduce FBG levels in db/db mice (P<0.01), improve OGTT (P<0.01) and ITT (P<0.01) levels, reduce SCr (P<0.01), BUN (P<0.01), UA (P<0.01) and 24-hour BUN (P<0.01), and increase ALB (P<0.01) and TP (P<0.01) levels. Pathological staining confirmed that the high-dose Shenqi Dihuangtang group could significantly reduce the glomerular mesangial matrix area and collagen deposition (P<0.01) and upregulate the positive expression rate of Nephrin (P<0.01). Western blot results showed that the high-dose Shenqi Dihuangtang group significantly downregulated the expression of TGF-β1 (P<0.01) and Smad2/3 (P<0.01) signal molecules and inhibited the protein levels of α-SMA (P<0.01), N-Cadherin (P<0.01), and Snail (P<0.01). ConclusionShenqi Dihuangtang can inhibit the TGF-β1/Smad signaling axis and block the renal EMT process, thereby improving DKD renal fibrosis damage. Further analysis of its key active components and clinical transformation pathways is needed in the future.

ObjectiveTo investigate the mechanism of Yangxin Tongmai Formula (养心通脉方, YTF) in trea-ting coronary heart disease with blood stasis syndrome based on DNA methylation. MethodsSeventy-two SD rats were randomly divided into a control group (n=12) and a modeling group (n=60). The modeling group was subjected to a high-fat diet, intragastric administration of vitamin D3, and subcutaneous injection of isoprenaline to establish the rat model of coronary heart disease with blood stasis syndrome. Forty-one successfully modeled rats were then randomly allocated into model group, YTF low-, medium-, and high-dose groups, and the atorvastatin calcium group, with 8 rats in each group and 1 rat reserved. The YTF low-, medium-, and high-dose groups received YTF at 6, 12, and 18 g/(kg·d) by gavage, respectively. The atorvastatin calcium group received atorvastatin calcium tablets at 1.8 mg/(kg·d) by gavage. The control group and the model group received 0.9% sodium chloride injection at 4 ml/(kg·d) by gavage. All administrations were performed once daily for 3 weeks. Twenty-four hours after the last administration, serum lipid levels including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), myocardial enzymes including cardiac troponin T (cTnT), creatine kinase MB (CK-MB), and lactate dehydrogenase (LDH), and inflammatory factors including interleukin-1β (IL-1β) and interleukin-10 (IL-10) were detected by ELISA. Pathological changes in myocardial tissue were observed via HE staining. Whole blood DNA methylation sequencing was used to analyze differential methylation gene expression among the control group, model group, and YTF high-dose group. Western Blotting was used to verify the protein levels of the key genes and downstream signaling pathways. ResultsCompared to the control group, the model group showed increased levels of TC, TG, LDL-C, cTnT, CK-MB, LDH, and IL-1β, along with decreased levels of HDL-C and IL-10 (P<0.05 or P<0.01). Compared to the model group, all treatment groups exhibited decreased levels of TC, LDL-C, CK-MB, and LDH, along with increased IL-10 levels. Among these, the high-dose YTF group demonstrated superior efficacy in reducing cTnT levels compared to the other TCM groups (P<0.05 or P<0.01). HE staining indicated that the YTF high-dose group ameliorated myocardial cell swelling, disordered arrangement, pyknosis, and disappearance of nuclei, thereby reducing myocardial cell damage. Whole blood DNA methylation sequencing identified 240 differentially methylated genes shared by the control group, model group, and YTF high-dose group, including 109 hypermethylated and 131 hypomethylated genes; eif2ak3 was identified as a key differentially methylated gene. Compared to the control group, the model group exhibited increased protein levels of eukaryotic translation initiation factor 2 alpha kinase 3 (eIf2ak3), phosphorylated protein kinase RNA-like endoplasmic reticulum kinase (p-PERK), activating transcription factor 4 (ATF4), C/EBP homologous protein (CHOP), and Bax, along with a decreased level of B-cell lymphoma-2 (Bcl-2) protein (P<0.05 or P<0.01). Compared to the model group, the YTF high-dose group showed decreased protein levels of eIf2ak3, p-PERK, ATF4, CHOP, and Bax, and an increased level of Bcl-2 protein (P<0.05 or P<0.01). ConclusionYTF may regulate key differentially methylated genes such as eIf2ak3 and the PERK/ATF4/CHOP signaling pathway, thereby inhibiting endoplasmic reticulum stress, reducing myocardial cell apoptosis, and exerting therapeutic effects in coronary heart disease blood stasis syndrome.

OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori (Hp) infection, and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1, 2021 to December 1, 2024 were selected and randomly divided into control group and study group, with 100 cases in each group. The control group was treated with classic quadruple therapy regimen (Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets). The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat (ITT) and per-protocol (PP) analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses, there was no significant difference of Hp eradication rates between the two groups (P>0.05). There was no significant difference in incidence of mild to moderate adverse reactions between the two groups (P>0.05). BMI ≤18.5 kg/m2, BMI >23.9 kg/m2, rural residence, concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment (P<0.05). CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2, BMI >23.9 kg/m2, rural residence, concomitant diabetes and concomitant heart disease.

Nuclear factor-kappa B (NF-κB) is an important intracellular transcription factor widely involved in the processes such as immune response, inflammatory response, cell proliferation, and apoptosis. The abnormal activation of the NF-κB signaling pathway plays a pivotal role in various liver diseases including chronic hepatitis, liver fibrosis, liver cirrhosis, and hepatocellular carcinoma. Extensive studies have shown that inhibiting NF-κB activity may effectively reduce inflammation and fibrosis and improve metabolic disorders. Several natural compounds, such as matrine and salvianolic acid B, have shown the potential in suppressing NF-κB activity, thereby exerting anti-inflammatory, anti-fibrotic, and anti-tumor effects. This article systematically reviews the critical role of the NF-κB signaling pathway in liver diseases and its potential as a therapeutic target, in order to highlight its potential as a therapeutic target for liver diseases and provide new directions for the treatment of liver diseases.

BACKGROUND:
Pulmonary arterial hypertension (PAH) presents a significant health burden in Asia and remains a critical challenge. This study aims to delineate the PAH burden in Asia from 1990 to 2021.
METHODS:
Using the latest data from the Global Burden of Disease 2021, we evaluated and analyzed the distributions and patterns of PAH disease burden among various age groups, sexes, regions, and countries in Asia. Additionally, we examined the associations between PAH disease burden and key health system indicators, including the socio-demographic index (SDI) and the universal health coverage (UHC) index.
RESULTS:
In 2021, there were 25,989 new PAH cases, 103,382 existing cases, 13,909 PAH-associated deaths, and 385,755 DALYs attributed to PAH in Asia, which accounted for approximately 60% of global PAH cases. The age-standardized rates (ASRs) for prevalence and deaths were 2.05 (95% uncertainty interval [UI]: 1.66-2.52) per 100,000 population and 0.31 (95% UI: 0.23-0.38) per 100,000 population, respectively. From 1990 to 2021, Asia reported the lowest ASRs for PAH prevalence but the highest ASRs for deaths compared to other continents. While the ASRs for prevalence increased slightly, ASRs for mortality and DALYs decreased over time. This increasing burden of PAH was primarily driven by population growth and aging. The burden was especially pronounced among individuals aged ≥60 years and <9 years, who collectively accounted for the majority of deaths and DALYs. Moreover, higher SDI and UHC levels were linked to reduced incidence, but higher prevalence rates.
CONCLUSIONS
Although progress has been made in reducing PAH-related mortality and DALYs, the disease continues to impose a substantial burden in Asia, particularly among older adults and young children. Region-specific health policies should focus on improving early diagnosis, expanding access to treatment, and effectively addressing the growing PAH burden in the region.

Processing for deodorization is widely used in the production of animal-derived Chinese medicinal materials. In this study, Heracles Neo ultra-fast gas-phase electronic nose combined with chemometrics was employed to analyze the overall odor difference of Cervi Cornu Pantotrichum(focusing on that derived from Cervus nippon Temminck in this study) before and after processing. The results showed that the electronic nose effectively distinguished between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. HS-GC-MS was used to identify and quantify the volatile components in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum, and 35 and 37 volatile components were detected in the medicinal materials and decoction pieces, respectively. The medicinal materials and decoction pieces contained 28 common volatile components contributing to the odor of Cervi Cornu Pantotrichum. The odor activity value(OAV) of each volatile component was calculated based on the olfactory threshold and relative content. The results showed that there were 17 key odor substances such as isovaleraldehyde, 2-methylbutanal, isobutyraldehyde, hexanal, and methanethiol in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. All of them had bad odor and were the main source of the odor of Cervi Cornu Pantotrichum. The results of principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) showed that there were significant differences in volatile components between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. Based on the thresholds of P<0.05 and Variable Importance in Projection(VIP)>1, 21 differential volatile odor components were screened out. Among them, isopentanol, isovaleraldehyde, 2-methylbutanal, n-nonanal, and dimethylamine were the key differential odor compounds between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. The odor compounds and their relative content reduced, and some flavor substances such as esters were produced after processing with wine, which was the main reason for the reduction of the odor after processing of Cervi Cornu Pantotrichum.

Quality control is a key link in the modernization process of traditional Chinese medicine(TCM). Studies have shown that the effects of active components in TCM depend on not only their chemical composition but also their suitable physical forms and states. The physical phase structures, such as micelles, vesicles, gels, and nanoparticles, can improve the solubility, delivery efficiency, and targeting precision of active components. These structures significantly enhance the pharmacological activity while reducing the toxicity and side effects, demonstrating functional activity surpassing that of active components and highlighting the key effects of "structures" on "functions" of active components. Taking the physical phase structure as a breakthrough point, this paper outlines the common types of TCM physical phase structures. Furthermore, this paper explores how to realize the quality upgrading of TCM through the precise regulation of physical phase structures based on the current applications and potential of TCM physical phase structures in processing to increase the efficacy and reduce the toxicity, compounding and decocting processes, drug delivery systems, and quality control, aiming to provide novel insights for the future quality control of TCM.

OpenSim is an open source, free motion simulation and gait analysis software, which can be used to dynamically simulate and analyze the complex motion of the human body, and is widely used in human biomechanical research. Since OpenSim can analyze multi-dimensional motion data such as muscle strength, joint torque, and muscle synergistic activation during human movement, it can be used to study the biomechanical mechanism of musculoskeletal imbalance diseases and various treatment methods in TCM orthopedics, and has a broad application prospect in the field of TCM orthopedics. By the analysis of the basic characteristics, elements, analysis process, and application prospects of OpenSim, it is concluded that OpenSim musculoskeletal model has a large application space in the field of traditional Chinese medicine orthopedic, which is helpful to explain the pathogenesis and mechanism of diseases, and promote the precision diagnosis and treatment of orthopedics diseases;the application of OpenSim musculoskeletal model can solve the problem that the previous research paid attention to the bone malalignment and not enough attention to the tendon, and provide a new method for the research of orthopedic diseases. At present, there are still problems in the promotion and application of OpenSim, such as large equipment requirements and high operation threshold. Therefore, multidisciplinary cooperation, clinical research, and data sharing are the basic research strategies in this field.
