Compound 1 is a new phenylethanol glycoside, which was identified as neomartynoside A. Compound 2 was isolated from Rehmannia glutinosa for the first time. In addition, compounds 2, 6 and 7 significantly increased relative glucose consumption, showing potential hypoglycemic activity.

ObjectiveTo multidimensionally analyze the clinical effects of Qianyang Yuyin granules on elderly hypertensive patients through an "energy-inflammation-aging" network. MethodsRelevant datasets were retrieved from the GEO database. Gene set enrichment analysis （GSEA） was performed on the gene expression profiles of peripheral blood cells from patients with essential hypertension in dataset GSE24752. The GSEA referenced "GO gene sets" and "KEGG gene sets" to identify significantly enriched gene sets. A clinical trial was conducted using a randomized controlled study design. A total of 40 patients meeting the inclusion criteria were enrolled. The control group received standard antihypertensive treatment with angiotensin receptor blockers （ARBs） or combined calcium channel blockers （CCBs）. In contrast，the treatment group received Qianyang Yuyin Granules in addition to the standard treatment for 12 weeks. Blood pressure levels and clinical efficacy were observed，and changes in energy metabolism indicators，DNA damage markers，and senescence-associated secretory phenotype （SASP） in blood were measured using ELISA before and after treatment. ResultsGSEA results indicated significant energy metabolism dysregulation in hypertensive patients. Clinical findings showed that both groups achieved blood pressure control without significant intergroup differences. In terms of clinical efficacy，the treatment group had a significantly higher effective rate compared to the control group （95% vs 65%，P0.05）. After treatment，the treatment group showed a significant increase in NAD⁺ levels （P0.01），with higher levels compared to the control group （P0.05）. The treatment group also exhibited a greater reduction in DNA damage marker 8-OHdG （P0.01） and cell adhesion factors ICAM-1 and VCAM-1 （P0.01） compared to the control group. Pro-inflammatory cytokines IL-1β and IL-6 were significantly reduced in the treatment group （P0.01），with greater reductions compared to the control group （P0.05，P0.01）. Anti-inflammatory cytokines IFN-α，IL-4，and IL-10 were significantly elevated in the treatment group （P0.01），with higher levels compared to the control group （P0.01）. No significant adverse reactions were reported in either group. ConclusionThe "energy- inflammation- aging" network plays an important role in the pathological mechanism of hypertension patients. Qianyang Yuyin granules may delay the aging process by increasing patients' energy metabolism levels，reducing DNA oxidative damage，and maintaining the balance of inflammatory factors.

The thought of medicine and food homology and substances with both edible and medicinal values are an important part of China's excellent traditional culture and medicine treasure, playing an important role in human diet and health maintenance for thousands of years. Substances with both edible and medicinal values are a standardized name governed by existing regulations, and many substances with both edible and medicinal values in the list lack important information such as original plants and edible and medicinal parts. Some substances change as the relevant regulations change, which confuses the use and regulation. According to the definition and inclusion conditions of substances with both edible and medicinal values in the Regulation of Substances with Both Edible and Medicinal Values Catalogue, this paper comprehensively reviewed the first batch of 87 substances with both edible and medicinal values published in 2002 by collecting information and investigating the practical application. Some substances supplemented, deleted, and revised were analyzed and discussed, and a complete revised list was compiled, encompassing a total of 90 substances, which were when combined with the 19 substances of the last three batches(published in 2019, 2023, and 2024), amounted to a total of 109 substances. In addition, the substances not currently in the published list but have both edible and medicinal values according to the latest definition were summarized, which revealed at least 27 other substances. Therefore, there were at least 136 substances with both edible and medicinal values. Additionally, the potential substances that could be included in the list of substances with edible and medicinal values were prospected, providing a focus for future expansion of the list. This paper systematically reviewed and revised the list of substances with both edible and medicinal values to lay a foundation for the regulatory authorities to revise the catalog of these substances and provide basic information for promoting the new quality productive forces in the health field and boosting the orderly and rapid development of the big health industry.

This study aims to explore whether Albiziae Cortex-Tribuli Fructus can exert an anti-hepatic fibrosis effect by regulating the nuclear factor E2-related factor 2(Nrf2)/NOD-like receptor protein 3(NLRP3)/cysteine protease-1(caspase-1) pathway and analyze its potential mechanism. In the in vivo experiment, a mouse model of hepatic fibrosis was established by subcutaneous injection of carbon tetrachloride. The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), collagen type Ⅳ(ColⅣ), laminin(LN), procollagen type Ⅲ(PCⅢ), and hyaluronic acid(HA) in the serum of mice were measured using a fully automated biochemical analyzer and ELISA. Hematoxylin and eosin(HE) and Masson staining were used to observe inflammation and collagen fiber deposition in the liver tissue. Western blot and RT-qPCR were employed to detect the protein and mRNA expression of collagen type Ⅰ(collagen Ⅰ), α-smooth muscle actin(α-SMA), Nrf2, NLRP3, gasdermin D(GSDMD), and caspase-1 in the hepatic tissue. In the in vitro experiment, human hepatic stellate cells(HSC-LX2) were pretreated with Nrf2 agonist or inhibitor, followed by the addition of blank serum, AngⅡ + blank serum, and AngⅡ + Albiziae Cortex-Tribuli Fructus-containing serum for intervention. Western blot was used to detect the protein expression of Nrf2, NLRP3, GSDMD, caspase-1, α-SMA, GSDMD-N, and apoptosis-associated speck-like protein(ASC) in cells. DCFH-DA fluorescence probe was used to detect the cellular ROS levels. The results from the in vivo experiment showed that, compared with the model group, Albiziae Cortex-Tribuli Fructus significantly reduced the serum levels of AST, ALT, ColⅣ, LN, PCⅢ, and HA, reduced the infiltration of inflammatory cells and collagen fiber deposition in the liver tissue, significantly upregulated the protein and mRNA expression of Nrf2 in the liver tissue, and significantly downregulated the protein and mRNA expression of collagen I, α-SMA, NLRP3, GSDMD, and caspase-1 in the liver tissue. The results from the in vitro experiment showed that Nrf2 activation decreased the protein expression of NLRP3, GSDMD, caspase-1, α-SMA, GSDMD-N, ASC, and ROS levels in HSC-LX2, while Nrf2 inhibition showed the opposite trend. Furthermore, Albiziae Cortex-Tribuli Fructus-containing serum directly decreased the expression of the above proteins and ROS levels. In conclusion, Albiziae Cortex-Tribuli Fructus can effectively improve hepatic fibrosis, and its mechanism of action may involve inhibiting pyroptosis through the regulation of the Nrf2/NLRP3/caspase-1 pathway.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

Objective:To investigate the clinical benefit and application value of the Da Vinci robotic surgical system through bilateral axillary areolar approach in cervical lymph node dissection in obese thyroid carcinoma patients.Methods:The clinical data of 117 patients with thyroid cancer admitted to the thyroid and breast surgery Department of the 960th Hospital of the Chinese PLA Joint Logistic Support Force from January 2018 to June 2023 were retrospectively analyzed. There were 55 males and 62 females, aged from 17 to 64 years, with an average age of (36.05±8.77) years. According to body mass index (BMI), patients were divided into normal group (18.5 kg/m 2≤BMI< 24 kg/m 2, n=60) and obese group (BMI≥28 kg/m 2, n=57). Gender, age, BMI, operation time, postoperative drainage fluid volume, tumor diameter, central lymph node dissection and number of metastasis, cervical lymph node dissection and number of metastasis, postoperative hospital stay, postoperative aesthetic satisfaction score and surgical complications of the two groups were analyzed. SPSS 26.0 statistical software was used to analyze the data. Results:All of patients completed the operation successfully, and neither group was transferred to open surgery. The BMI of obese group was higher than that of normal group [(31.35±3.08) kg/m 2vs (22.53±0.82) kg/m 2, t=20.97, P<0.05]. The maximum tumor diameter in the obese group was greater than that in the normal group [(13.81±10.70) mm vs (10.42±5.53) mm, t=2.17, P<0.05]. There were no significant differences in operation time, number of central lymph node dissection and metastasis, number of cervical lymph node dissection and metastasis and postoperative complications between the two groups ( P>0.05). Conclusions:Utilization of the Da Vinci robotic surgical system via the BABA approach demonstrates both safety and feasibility in obese patients with thyroid carcinoma undergoing lateral cervical lymph node dissection. Importantly, this technique does not increase the risk of surgical complications, thus providing a novel alternative for lateral cervical lymph node dissection in obese thyroid carcinoma patients.

BACKGROUND:Sema3A is a power secretory osteoprotective factor.However,studies about Sema3A-modified dental pulp stem cells(Sema3A-DPSCs)are rare. OBJECTIVE:To explore the osteogenic differentiation ability of Sema3A-DPSCs and their regulatory effect on the osteogenic differentiation of the pre-osteoblast cell line MC3T3-E1. METHODS:First,Sema3A-DPSCs were constructed using a lentivirus infection system carrying the Sema3A gene.Control lentivirus-treated DPSCs(Vector-DPSCs)were used as controls.Sema3A-DPSCs or Vector-DPSCs were co-cultured with proosteoblast line MC3T3-E1 at the ratio of 1∶1 and 1∶3 for 24 hours.Finally,the Sema3A-DPSCs,Vector-DPSCs and their co-cultured cells with MC3T3-E1 were cultured for osteogenic induction and differentiation.Osteogenic gene expression was detected by alkaline phosphatase staining,alizarin red staining and real-time quantitative RT-PCR to evaluate osteogenic differentiation ability. RESULTS AND CONCLUSION:(1)Sema3A mRNA and protein expression levels in Sema3A-DPSCs were significantly up-regulated.The level of secreted Sema3A in cell supernatant was up-regulated.(2)Compared with the Vector-DPSCs,mRNA expressions of osteogenic genes alkaline phosphatase,Runt-related transcription factor 2,osteocalcin and Sp7 transcription factors in Sema3A-DPSCs were up-regulated;the activity of alkaline phosphatase was enhanced,and the formation of mineralized nodules increased.(3)There were no obvious differences in proliferation between Sema3A-DPSCs and Vector-DPSCs.(4)Compared with MC3T3-E1/Vector-DPSCs co-culture system,the expression of MC3T3-E1 osteogenic genes was up-regulated,and the total alkaline phosphatase activity was enhanced and more mineralized nodules were formed in the MC3T3-E1/Sema3A-DPSCs co-culture system.(5)The results suggest that overexpression of Sema3A can enhance the osteogenic differentiation of DPSCs.Overexpression of Sema3A in DPSCs can promote osteogenic differentiation of MC3T3-E1 in the DPSCs/MC3T3-E1 co-culture system.

To understand Helicobacter pylori's drug resistance,genetic diversity,and relationship with clinical diseases in the Guiyang and Qiannan minority areas of Guizhou Province,we collected samples through endoscopy,and isolated and cul-tured H.pylori.The drug resistance and genotype characteristics were determined.The differences in different regions and dis-ease types were compared,and the structural characteristics of H.pylori and mixed infections with different strains of H.py-lori in Qiannan Prefecture were analyzed.A difference in the composition ratio of EPYIA typing in the cagA variable region was observed between the two areas(P=0.012),and the composition ratio of the vacA genotype differed(P=0.000).A total of 94.6％(53/56)new sequences of H.pylori strains from two regions were obtained by MLST.The rate of infection by H.pylori mixed with different strains was 44.4％in Qiannan Pre-fecture,and no significant difference was observed in the com-position of H.pylori mixed infections among patients with dif-ferent clinical diseases(P=0.349).Differences in EPI YA typ-ing and the vacA genotype composition ratio in the cagA varia-ble region of H.pylori were observed between the Qiannan Prefecture and Guiyang City.

Atherosclerosis caused by disorders of lipid metabolism is the main pathological basis of atherosclerotic cardiovascular disease.Statins are the cornerstone of lipid-modulating therapy for this type of disease,but in practice there are still some patients with suboptimal lipid management.Proprotein convertase subtilisin/kexin type 9(PCSK9)inhibitors have been gradually applied as a new class of lipid-modulating drugs for the treatment in patients with this type of disease,and recent studies have shown that in addition to regulating lipid metabolism,PCSK9 inhibitors also have potential anti-inflammatory and anti-platelet activation effects.This article sorts out the multiple pharmacological mechanisms of action of PCSK9 inhibitors and the current status of clinical research of PCSK9 inhibitors.Besides,it discusses the factors that may affect the efficacy of PCSK9 inhibitors,in order to provide a reference for the safe and rational medication of PCSK9 inhibitors.
