Chronic heart failure (CHF) is a complex clinical syndrome caused by ventricular dysfunction, with mitochondrial energy metabolism disorder being a critical factor in disease progression. Heart-Yang deficiency syndrome, as the core pathogenesis of CHF, persists throughout the disease course. Insufficiency of heart-Yang leads to weakened warming and propelling functions, resulting in the accumulation of phlegm-fluid, blood stasis, and dampness. This eventually causes Qi stagnation with phlegm obstruction and blood stasis with water retention, forming a vicious cycle that exacerbates disease progression. According to the theory of reinforcing Yang, the clinical experience of the traditional Chinese medicine (TCM) master Tang Zuxuan in treating CHF with heart-Yang deficiency syndrome, and achievements from molecular biological studies, this study innovatively proposes an integrated research framework of "TCM syndrome differentiation and staging-mitochondrial metabolism mechanisms-intervention with Yang-reinforcing prescriptions" which is characterized by the integration of traditional Chinese and Western medicine. Heart-Yang deficiency syndrome is classified into mild (Stage Ⅰ-Ⅱ), severe (Stage Ⅲ), and critical (Stage Ⅳ) stages. The study elucidates the precise correlations between the pathogenesis of each stage and mitochondrial metabolism disorders from theoretical, pathophysiological, and therapeutic perspectives. The mild stage is characterized by impaired biogenesis and substrate-utilization imbalance, corresponding to heart-Yang deficiency and phlegm-fluid aggregation. Linggui Zhugantang and similar prescriptions can significantly improve the expression of peroxisome proliferator-activated receptor gamma co-activator-1α(PGC-1α)/silent information regulator 2 homolog 1 (SIRT1) and ATPase activity. The severe stage centers on oxidative stress and structural damage, reflecting Yang deficiency with water overflow and phlegm-blood stasis intermingling. At this stage, Zhenwu Tang and Qiangxin Tang can effectively mitigate oxidative stress damage, increase adenosine triphosphate (ATP) content, and repair mitochondrial structure. The critical stage arises from calcium overload and mitochondrial disintegration, leading to the collapse of Yin-Yang equilibrium. At this stage, Yang-restoring and crisis-resolving prescriptions such as Fuling Sini Tang and Qili Qiangxin capsules can inhibit abnormal opening of the mitochondrial permeability transition pore (MPTP), reduce cardiomyocyte apoptosis rate, and protect mitochondrial function. By summarizing the characteristics of mitochondrial energy metabolism disorders at different stages of CHF, this study explores the application of the theory of reinforcing Yang in treating heart-Yang deficiency syndrome and provides new insights for the clinical diagnosis and treatment of CHF.

ObjectiveTo explore the mechanism of ventricular remodeling mediated by the p38 mitogen-activated protein kinase (MAPK)/nuclear factor kappa B (NF-κB) signaling pathway in the rat model of chronic heart failure (CHF) with heart-blood stasis syndrome, as well as the intervention effect of Danhong injection. MethodsIn vivo experiment: SPF-grade male SD rats were assigned via the random number table method into 4 groups: Sham operation, model, captopril (8.8 mg·kg-1), and Danhong injection (6.0 mL·kg-1). The model of CHF with heart-blood stasis syndrome was established by abdominal aortic constriction, and the sham operation group only underwent laparotomy without constriction. All the groups were treated continuously for 15 days. The tongue color of rats was observed. Echocardiography, hemorheology, heart mass index (HMI), and left ventricular mass index (LVMI) were measured. Hematoxylin-eosin (HE) staining and Masson staining were performed to observe the pathological and fibrotic changes of the myocardial tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), angiotensin Ⅱ (AngⅡ), tumor necrosis factor-α (TNF-α), and Creactive protein (CRP) in the serum, as well as the levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in the myocardial tissue. Western blot was used to quantify the protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue. In vitro experiment: H9C2 cardiomyocytes were treated with 1×10-6 mol·L-1 AngⅡ to establish a model of myocardial hypertrophy. H9C2 cardiomyocytes were allocated into normal, model, inhibitor + Danhong injection, Danhong injection (20 mL·L-1), and inhibitor (SB203580, 5 μmol·L-1) groups. CCK-8 assay was used to detect the viability of H9C2 cardiomyocytes. Rhodamine-labeled phalloidin staining was used to reveal the area of cardiomyocytes. Real-time PCR was performed to determine the mRNA levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). Western blot was used to assess the protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65. ResultsIn vivo experiment: Compared with the sham operation group, the model group showed purplish-dark tongue with decreased R, G, B values of the tongue surface (P<0.01), increased whole blood viscosity (at low, medium, and high shear rates) (P<0.01), decreased left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01), increased left ventricular end-diastolic diameter (LVIDd), left ventricular end-systolic diameter (LVIDs), and left ventricular posterior wall thickness at end-diastole (LVPWd) (P<0.01), raised LVMI and HMI (P<0.01), and elevated levels of NT-proBNP, TNF-α, IL-6, and CRP in the serum and MMP-2 and MMP-9 in the myocardial tissue (P<0.01). The HE and Masson staining of the myocardial tissue showed compensatory myocardial hypertrophy, fibrosis, and massive inflammatory cell infiltration in the model group. Additionally, the model group presented up-regulated protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue (P<0.01). Compared with the model group, each administration group showed increased R, G, B values of the tongue surface (P<0.05, P<0.01), decreased whole blood viscosity (at low, medium, and high shear rates) (P<0.05, P<0.01), increased LVEF and LVFS (P<0.01), decreased LVIDd, LVIDs, and LVPWd (P<0.05, P<0.01), declined LVMI and HMI (P<0.05, P<0.01), and lowered levels of NT-proBNP, TNF-α, IL-6, and CRP in the serum and MMP-2 and MMP-9 in the myocardial tissue (P<0.01). HE and Masson staining showed alleviated compensatory myocardial hypertrophy, reduced fibrosis, and decreased expression of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 in the myocardial tissue (P<0.01). In vitro experiment: When the concentration of Danhong injection reached 20 mL·L-1, the survival rate of H9C2 cardiomyocytes was the highest (P<0.01). Compared with the normal group, the model group showed up-regulated mRNA levels of ANP and BNP (P<0.01), increased relative cell surface area (P<0.01), and raised protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 (P<0.01). Compared with the model group, each administration group showed down-regulated mRNA levels of ANP and BNP (P<0.01), reduced relative cell surface area (P<0.05, P<0.01), and down-regulated protein levels of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 (P<0.05, P<0.01). ConclusionDanhong injection can regulate ventricular remodeling through the p38 MAPK/NF-κB pathway, thereby exerting a protective effect on the rat model of CHF with heart-blood stasis syndrome.

OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger, and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content, total ash, and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides, including 14 flavonoids, 15 iridoids, 10 organic acids, 2 alkaloids and 8 other compounds. Among them, 42 components were detected in raw G. jasminoides, 28 in ginger-processed G. jasminoides, and 21 components were common to both. After processing with ginger, raw G. jasminoides lost 21 components (including iridoids, flavonoids, alkaloids, and others), while 7 chemical components were added (including coumarins, organic acids, organic acid esters, and flavonoids). For the 15 batches of ginger-processed G. jasminoides, the water content ranged from 5.64% to 7.11%, total ash from 2.92% to 4.87%, and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ were 0.108 7, 0.542 2, 0.565 0, and 0.012 5 mg/g, respectively. CONCLUSIONS After processing with ginger, G. jasminoides loses 21 components, while 7 new components are added. Differences are observed in the water content, total ash, ethanol-soluble extract, and the contents of genipin gentiobioside, geniposide, crocin Ⅰ, and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably, samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract, while samples from Jiangxi have a high content of crocin Ⅰ.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

In recent years, gastrointestinal stromal tumors (GIST) have increased incidence and mortality, and most GIST is caused by the activation mutation of the c-KIT gene. Therefore, c-KIT has become a promising therapeutic target of GIST. At present, the drugs approved for the treatment of GIST including imatinib, sunitinib, regorafenib and ripretinib, are mostly prone to developing resistance and accompanied by various degrees of adverse reactions. Therefore, there is an urgent need to develop new c-KIT inhibitors to solve the problem of resistance. In this study, we investigated the anti-tumor effect of a novel c-KIT inhibitor PN17-1 on gastrointestinal stromal tumor GIST-882 cells

Objective To understand the influencing factors of chronic dyslipidemia in T2DM patients who signed a contract for diabetes point system management in Qingpu District, and to provide a basis for comprehensive intervention and prevention and control of dyslipidemia in T2DM patients and to optimize the management strategy of Qingpu District diabetes point system. Methods Among the T2DM patients who signed the diabetes point system from 2017 to 2023, patients with chronic dyslipidemia and normal blood lipids were selected and included in the case group and the control group, respectively. A case-control study was conducted with 1:1 matching by age and gender to analyze the factors influencing dyslipidemia. Results Multifactorial paired logistic regression analysis showed that overweight/obesity and central obesity and smoking in T2DM patients increased the risk of dyslipidemia by 1.93, 2.27, and 2.16 times, respectively. Long-term use of lipid-lowering drugs, duration of diabetes for 5 years or more, regular physical exercise, knowledge of blood lipid status, and married status could reduce the risk of dyslipidemia in T2DM patients (OR values were 0.547, 0.452, 0.685, 0.386 and 0.354, respectively). Current complications (history of stroke, coronary heart disease, and renal insufficiency) were also associated with dyslipidemia (OR=1.802, 95% CI:1.125-2.888). Conclusion The management of diabetes point system in Qingpu District should strengthen the feedback and interpretation of blood lipid monitoring results, improve patients’ health awareness of blood lipid management, and actively take comprehensive management of lifestyle intervention and drug treatment to effectively control blood lipid and reduce the occurrence of related complications.

[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.

This study aims to explore the mechanism through which Yishen Jiangtang Decoction(YSJTD) regulates endoplasmic reticulum stress(ERS)-mediated NOD-like receptor thermal protein domain associated protein 3(NLRP3) inflammasome to improve diabetic nephropathy(DN) in db/db mice. Thirty db/db mice were randomly divided into the model group, YSJTD group, ERS inhibitor 4-phenylbutyric acid(4-PBA) group, with 10 mice in each group. Additionally, 10 db/m mice were selected as the control group. The YSJTD group was orally administered YSJTD at a dose of 0.01 mL·g~(-1), the 4-PBA group was orally administered 4-PBA at a dose of 0.5 mg·g~(-1), and the control and model groups were given an equal volume of carboxylmethyl cellulose sodium. The treatments were administered once daily for 8 weeks. Food intake, water consumption, and body weight were recorded every 2 weeks. After the intervention, fasting blood glucose(FBG), glycosylated hemoglobin(HbA1c), urine microalbumin(U-mALB), 24-hour urine volume, serum creatinine(Scr), and blood urea nitrogen(BUN) were measured. Inflammatory markers interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected using the enzyme-linked immunosorbent assay(ELISA). Renal pathology was assessed through hematoxylin-eosin(HE), periodic acid-Schiff(PAS), and Masson staining, and transmission electron microscopy(TEM). Western blot was used to detect the expression levels of glucose-regulated protein 78(GRP78), C/EBP homologous protein(CHOP), NLRP3, apoptosis-associated speck-like protein containing CARD(ASC), cysteinyl aspartate-specific proteinase(caspase-1), and gasdermin D(GSDMD) in kidney tissues. The results showed that compared to the control group, the model group exhibited poor general condition, increased weight and food and water intake, and significantly higher levels of FBG, HbA1c, U-mALB, kidney index, 24-hour urine volume, IL-1β, and IL-18. Compared to the model group, the YSJTD and 4-PBA groups showed improved general condition, increased body weight, decreased food intake, and lower levels of FBG, U-mALB, kidney index, 24-hour urine volume, and IL-1β. Specifically, the YSJTD group showed a significant reduction in IL-18 levels compared to the model group, while the 4-PBA group exhibited decreased water intake and HbA1c levels compared to the model group. Although there was a decreasing trend in water intake and HbA1c in the YSJTD group, the differences were not statistically significant. No significant differences were observed in BUN, Scr, and kidney weight among the groups. Renal pathology revealed that the model group exhibited more severe renal damage compared to the control group. Kidney sections from the model group showed diffuse mesangial proliferation in the glomeruli, tubular edema, tubular dilation, significant inflammatory cell infiltration in the interstitium, and increased glycogen staining and blue collagen deposition in the basement membrane. In contrast, the YSJTD and 4-PBA groups showed varying degrees of improvement in renal damage, glycogen staining, and collagen deposition, with the YSJTD group showing more significant improvements. TEM analysis indicated that the model group had extensive cytoplasmic edema, homogeneous thickening of the basement membrane, fewer foot processes, and widening of fused foot processes. In the YSJTD and 4-PBA groups, cytoplasmic swelling of renal tissues was reduced, the basement membrane remained intact and uniform, and foot process fusion improved.Western blot results indicated that compared to the control group, the model group showed upregulation of GRP78, CHOP, GSDMD, NLRP3, ASC, and caspase-1 expression. In contrast, both the YSJTD and 4-PBA groups showed downregulation of these markers compared to the model group. These findings suggest that YSJTD exerts a protective effect against DN by alleviating NLRP3 inflammasome activation through the inhibition of ERS, thereby improving the inflammatory response in db/db DN mice.

OBJECTIVE To establish the HPLC fingerprint of Xintong granules and the quantitative analysis of multi- components by single-marker method (QAMS) to determine the contents of 7 components, so as to provide a scientific basis for their quality control. METHODS HPLC method was used to establish the fingerprints for 10 batches of Xintong granules (No. S1- S10), and similarity evaluation, cluster analysis (CA) and partial least squares-discriminant analysis (PLS-DA) were performed. At the same time, the contents of seven components, including puerarin, daidzin, calycosin-7-O- β -D-glucoside, stilbene glycoside, naringin, icariin and tanshinone ⅡA, were determined by QAMS method, and were compared with the results of external standard method. RESULTS A total of 18 common peaks were marked and 7 peaks were identified in the HPLC fingerprints for 10 batches of Xintong granules, namely puerarin (peak 4), daidzin (peak 7), calycosin-7-O-β-D-glucoside (peak 9), stilbene glycoside (peak 10), naringin (peak 12), icariin (peak 17), and tanshinone ⅡA (peak 18); the similarities among them were more than 0.990, and CA and PLS-DA results showed that S4-S5,S8-S10,S1-S3 and S6-S7 were clustered into three categories, respectively. Using naringin as the internal standard, the contents of puerarin, daidzin, calycosin-7-O-β-D-glucoside, stilbene glycoside, icariin and tanshinone ⅡA were determined to be 7.868 1-10.181 2, 1.709 2-2.374 1, 0.285 2-0.326 3, 1.024 1- 1.523 9, 0.140 2-0.290 4, and 0.077 1-0.219 4 mg/g, respectively, by the QAMS. These results showed no significant differences compared to those obtained by the external standard method. CONCLUSIONS Established HPLC fingerprint and QAMS method are convenient, stable and accurate, which can provide a basis for the quality evaluation of Xintong granules.
