ObjectiveTo investigate the mechanisms by which Renshentang treats atherosclerosis (AS) in mice, focusing on the regulation of endothelial inflammatory responses mediated by transient receptor potential vanilloid subtype 1 (TRPV1). MethodsAn AS model was established in apolipoprotein E knockout (ApoE-/-) mice fed a high-fat diet. The mice were randomly divided into a simvastatin group (0.02 g·kg-1·d-1) and low-, medium-, and high-dose Renshentang groups (1.77, 3.54, 7.08 g·kg-1·d-1), with 12 mice in each group. ApoE-/- mice were fed a high-fat diet and treated simultaneously. C57BL/6J mice fed a normal diet served as the normal group (n=9). After continuous administration for 12 weeks, mice were anesthetized and the aortas were collected. Oil Red O staining was used to observe lipid plaque formation in the aorta. Hematoxylin-eosin (HE) staining was performed to examine pathological changes in the aortic root. Immunohistochemistry was used to analyze the levels of pro-inflammatory factors tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), as well as the expression of TRPV1, phosphorylated phosphoinositide 3-kinase (p-PI3K), and phosphorylated protein kinase B (p-Akt) in the aortic root. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect endothelial nitric oxide synthase (eNOS) mRNA expression in the aorta, and Western blot was used to detect TRPV1 protein expression. ResultsCompared with the normal group, the model group showed a significant increase in aortic plaque formation (P<0.01) and significantly elevated levels of TNF-α and IL-1β in the aortic root (P<0.01). The expression levels of TRPV1, p-PI3K, and p-Akt were decreased (P<0.05, P<0.01), and eNOS mRNA expression was reduced (P<0.05, P<0.01). Compared with the model group, all Renshentang groups significantly reduced aortic plaque formation (P<0.01), significantly decreased TNF-α and IL-1β levels (P<0.01), and markedly increased the expression levels of TRPV1, p-PI3K, p-Akt, and eNOS mRNA (P<0.05, P<0.01). ConclusionRenshentang may inhibit endothelial inflammation and suppress the formation of AS by increasing TRPV1 protein expression and up-regulating the PI3K/Akt/eNOS signaling pathway, which may be one of the molecular mechanisms underlying its therapeutic effect against AS.

Alzheimer's disease (AD) is a common type of dementia, primarily characterized by cognitive and behavioral impairments as well as deficits in learning and memory. The progression of AD has imposed a significant economic burden on society and families. However, its exact pathogenesis has not yet been fully elucidated. Currently, available therapeutic drugs are limited and are often accompanied by serious adverse effects. Traditional Chinese medicines (TCMs) and their extracts are mostly natural products and possess advantages such as multi-pathway regulation and relatively few adverse reactions. Experimental studies have shown that TCMs exhibit great potential in the prevention and treatment of AD. For example, Huanglian Jieduang, Danggui Shaoyaosan, Kaixin San, Liuwei Dihuangwan, Buyang Huanwutang, as well as Ginseng Radix et Rhizoma, Astragali Radix, Uncariae Ramulus cum Uncis, Coptidis Rhizoma, Gardeniae Fructus, Ginkgo Folium, Salviae Miltiorrhizae Radix et Rhizoma, and Curcumae Longae Rhizoma, can reduce β-amyloid deposition, inhibit excessive Tau protein phosphorylation, restore mitochondrial function, alleviate oxidative stress, suppress neuroinflammation and apoptosis, repair synaptic function, and improve gut microbiota. This article mainly summarizes the effects of several TCMs and compound prescriptions on AD, aiming to provide a reference for subsequent TCM-based treatment of AD.

ObjectiveTo investigate the effect of Yaoshu Zhuyu Fang on the regulation of the microRNA-17-5P (miR-17-5P)/murine double minute 2 (MDM2)/p53 axis in the proliferation and apoptosis of rat intervertebral disc annulus fibrosus cells, and its potential molecular mechanism. MethodsIntervertebral disc annulus fibrosus tissues were obtained from 8-week-old SPF-grade male SD rats, and annulus fibrosus cells were isolated and obtained by enzyme digestion and mechanical dispersion. Annulus fibrosus cells were divided into 6 groups: Group C was the blank control group, in which annulus fibrosus cells were not treated with interleukin-1β (IL-1β) but were cultured in RPMI 1640 complete medium. Group β was the degeneration model group constructed by treating annulus fibrosus cells with 10 ng/mL IL-1β for 24 h. Group β+B was the IL-1β + blank serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then treated with RPMI 1640 medium containing 5% blank serum for 24 h. Group β+W was the IL-1β + Yaoshu Zhuyu Fang-containing serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then treated with RPMI 1640 medium containing 5% Yaoshu Zhuyu Fang-containing serum for 24 h. Group β+I was the IL-1β + miR-17-5P inhibitor group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then transfected with miR-17-5P inhibitor. Group β+I+W was the IL-1β + miR-17-5P inhibitor + Yaoshu Zhuyu Fang-containing serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then transfected with miR-17-5P inhibitor, and finally treated with RPMI 1640 medium containing 5% Yaoshu Zhuyu Fang-containing serum for 24 h. CCK-8 assay was used to detect cell survival rate. Flow cytometry was used to detect cell apoptosis. Real-time quantitative PCR was used to detect the expression levels of miR-17-5P, MDM2 mRNA, and p53 mRNA in cells. Western blotting was used to detect the protein expression levels of MDM2 and p53 in cells. Dual-luciferase reporter system was used to analyze the targeting relationship between miR-17-5P and MDM2. ResultsCompared with Group C, Group β showed a significant decrease in cell survival rate (P<0.001), a significant increase in cell apoptosis rate (P<0.001), significantly increased expression of miR-17-5P, p53 mRNA, and p53 protein (P<0.001), and significantly decreased expression of MDM2 mRNA and protein (P<0.001). Compared with Group β, Group β+W, Group β+I, and Group β+I+W showed significantly increased cell survival rate, significantly decreased apoptosis rate, significantly decreased expression of miR-17-5P, p53 mRNA, and p53 protein, and significantly increased expression of MDM2 mRNA and protein (P<0.001). Moreover, changes in the above indicators were greater in Group β+I+W (P<0.001). Circular RNA Interactome predicted that miR-17-5P had specific binding sites with the 3' untranslated region (3'UTR) of MDM2. Transfection of miR-17-5P mimic significantly reduced the luciferase expression level of co-transfected luciferase reporter plasmid containing wild-type MDM2 3'UTR (P<0.05), but had no significant effect on luciferase expression in cells co-transfected with luciferase reporter plasmid containing mutant MDM2 3'UTR (P>0.05). ConclusionYaoshu Zhuyu Fang down-regulates the expression of miR-17-5P, promotes the synthesis of MDM2 protein, thereby down-regulates p53, promotes proliferation, and inhibits the apoptosis of rat intervertebral disc annulus fibrosus cells.

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

OBJECTIVE To study the protective effect and potential mechanism of chikusetsu saponin Ⅳ a (chsⅣ) on renal function in diabetic nephropathy (DN) model rats. METHODS DN rat model was established by high-fat diet combined with streptozotocin injection. Thirty-six model rats were randomly divided into model group (i.g. administration of normal saline, high-fat diet), chsⅣ low-dose and high-dose groups (i.g. administration of 90, 180 mg/kg chsⅣ, high-fat diet), with 12 rats in each group. Additionally, 10 normal rats were set as the control group (i.g. administration of normal saline, regular diet). From the 5th to the 12th week after streptozotocin injection, they were given intragastric administration of relevant drug or normal saline, once a day. After the last medication, the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine and urine protein as well as the levels of reduced glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissues were measured. Additionally, the insulin resistance index was calculated. Hematoxylin-eosin, periodic acid-Schiff, and Masson staining techniques were employed to examine the histopathological alterations in the renal tissue. The expressions of Notch signaling pathway-related proteins in renal tissue were detected by immunohistochemical staining and Western blot methods. RESULTS Compared with model group, the histomorphological of renal tissues in the chsⅣ low- and high-dose groups were significantly improved, with significant decreases in renal histological scores, mesangial expansion index, and glomerulosclerosis scores ( P <0.05); the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine, urine protein and homeostasis model assessment for insulin resistance, as well as MDA content, the expression levels of Notch1, Notch intracellular domain, hairy and enhancer of Split 1 and Delta-like protein 1 in renal tissue were all significantly decreased ( P <0.05). The levels of GSH and SOD in renal tissue were significantly elevated ( P <0.05). Moreover, the improvement in these indicators was significantly more pronounced in the chsⅣ high-dose group compared to the chsⅣ low-dose group ( P <0.05). CONCLUSIONS ChsⅣ can ameliorate renal pathological damage and functional impairment in DN rats. Its underlying mechanisms include restoration of glucose homeostasis and insulin sensitivity, attenuation of renal oxidative stress, and suppression of aberrant Notch signaling pathway activation.

Objective To elucidate the causal relationships between colorectal cancer (CRC) and prevalent psychiatric disorders through a two-sample Mendelian randomization approach. Methods Utilizing publicly available genome-wide association study data, we explored the connections between CRC and various psychiatric disorders, including depression, anxiety, bipolar disorder, and schizophrenia. We applied three statistical analyses: inverse variance weighting, MR-Egger, and median weighting. Sensitivity analyses were conducted to ensure the reliability and validity of the results. Results Inverse variance weighting analysis showed no significant links between CRC and depression (P=0.090), anxiety (P=0.099), or schizophrenia (P=0.899). Conversely, a significant inverse relationship was found with bipolar disorder (P=0.010). Conclusion No causal connection exists between CRC and the psychiatric conditions of depression, anxiety, or schizophrenia. However, CRC may have a causal association with a reduced risk of bipolar disorder, further supporting the existence of the gut-brain axis.

Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.

ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy, to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian, and meanwhile, the contents of four index components(geniposide, paeoniflorin, hesperidin and paeonol) were quantitatively analyzed by high performance liquid chromatography(HPLC). Nonalcoholic fatty liver disease(NAFLD) rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group, model group, lovastatin group(1.8 mg·kg-1), combined decoction group(1.26 g·kg-1) and single decoction group(1.18 g·kg-1). After successful modeling, lovastatin group, combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day, and the control group and model group were given equal amounts of normal saline by intragastric administration, after 4 weeks of administration, the serum and liver tissues were collected, and the contents of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) in serum of rats were detected, and the liver pathological examination was carried out by hematoxylin-eosin(HE) staining and oil red O staining, so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian, and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide, paeoniflorin, hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples(P<0.01). The pharmacodynamic results showed that compared with the model group, both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats, reduce the serum levels of AST, ALT, TC, TG and LDL-C, increase the serum level of HDL-C, and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However, there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition, but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.
