ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

ObjectiveThis paper aims to investigate the potential molecular biological mechanism of Buyang Huanwu Tongfeng decoction in treating hyperuricemia and gouty arthritis by network pharmacology and molecular docking technology and preliminarily verify the mechanism through animal experiments. MethodsThe active ingredients and targets in the Buyang Huanwu Tongfeng decoction were obtained by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and ETCM databases. The DisGeNET and GeneCards databases were utilized to acquire disease targets associated with hyperuricemia and gouty arthritis. These disease targets were then intersected with drug targets to identify key targets. The R language ClusterProfiler package and Python were employed for conducting gene ontology(GO) enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) enrichment analysis. The regulatory network diagram of the drug-key target-function-pathway was visualized using Cytoscape 3.9.1 software, and the protein-protein interaction (PPI) network for key targets was depicted. Finally, the hub gene was determined through topological analysis. Auto Dock, PyMOL, and other software were used for molecular docking to explore the possible therapeutic mechanism of Buyang Huanwu Tongfeng decoction for hyperuricemia and gouty arthritis. In animal experiments, a composite rat model of hyperuricemia induced by intraperitoneal injection of oteracil potassium combined with gouty arthritis induced by the modified Coderre method was established. Through hematoxylin-eosin(HE) staining, uric acid test, enzyme linked immunosorbent assay(ELISA), Western blot, and real-time polymerase chain reaction(Real-time PCR), the molecular mechanism and key targets of Buyang Huanwu Tongfeng decoction for treating hyperuricemia and gouty arthritis were observed. ResultsAfter screening and removing duplicate values, 76 active ingredients and 15 key targets were finally obtained. GO enrichment analysis yielded that the treatment of hyperuricemia and gouty arthritis with Buyang Huanwu Tongfeng decoction was significantly associated with acute inflammatory response, astrocyte activation, regulation of interleukin (IL)-8 production, nuclear receptor activity, and binding of growth factor receptor. KEGG pathway enrichment analysis obtained that the key target genes were significantly associated with the IL-17 signaling pathway, advanced glycosylation end/receptor of advanced glycation endproducts(AGE/RAGE) signaling pathway, anti-inflammatory, and other pathways. PPI network indicated that albumin(ALB), peroxisome proliferator-activated receptor-γ (PPAR-γ), IL-6, IL-1β, and C-reactive protein(CRP) were the key protein targets. The molecular docking results showed that ALB had the strongest binding force with beta-carotene (β-carotene). Biochemical results showed that blood uric acid decreased in the Buyang Huanwu Tongfeng decoction groups. HE staining results showed that the low-dose (7.76 g·kg-1·d-1), medium-dose (15.53 g·kg-1·d-1), and high-dose (31.05 g·kg-1·d-1) groups of Buyang Huanwu Tongfeng decoction had different degrees of remission, and the remission of the high-dose group was the most obvious. Fibroblastic tissue hyperplasia in synovial joints accompanied with inflammatory cell infiltration, as well as inflammatory cell infiltration in renal tissue of the high-dose group was significantly reduced, followed by the medium-dose and low-dose groups, and the expression of ALB, PPAR-γ, IL-6, IL-1β, and CRP was down-regulated to different degrees. ConclusionBy regulating the targets such as ALB, PPAR-γ, IL-6, IL-1β, and CRP, inhibiting the PPAR-γ/nuclear transcription factor (NF)-κB pathway, and reducing AGEs/RAGE-mediated inflammation, Buyang Huanwu Tongfeng decoction exerts anti-inflammatory and analgesic effects and activates blood circulation and diuresis in the treatment of hyperuricemia and gouty arthritis.

AIM: To observe the changes of retinal nerve fiber layer(RNFL)thickness and radial peripheral capillary(RPC)density in patients with unilateral branch retinal vein occlusion(BRVO), and further analyze the correlation between RPC density and RNFL thickness.METHODS: Observational study. Totally 37 patients with unilateral BRVO diagnosed at the ophthalmology department of First Hospital of Qinhuangdao from October 2020 to January 2022 were selected, the 37 affected eyes were the unilateral BRVO group, and 37 fellow healthy eyes were the contralateral unaffected group, and 35 healthy individuals(35 right eyes were selected)without ocular diseases during the same period were selected as the normal control group. The best corrected visual acuity, intraocular pressure, anterior segment, fundus and optical coherence tomography angiography(OCTA)were examined in both eyes of all BRVO patients and healthy individuals. The central macular thickness(CMT), the RNFL thickness, and the optic disc-AV crossing distance(DAVD)were measured by built-in software of the OCTA equipment. The optimized U-net algorithm was used to eliminate the large blood vessels, and then the RPC density was calculated. The CMT, RNFL thickness and RPC density were compared among the three groups. And the correlations of the RPC density with the CMT, RNFL thickness, and the DAVD were investigated.RESULTS: Compared with the contralateral unaffected group and the normal control group, the CMT and the RNFL thickness were significantly thickened in the unilateral BRVO group(all P<0.05); there were no statistical differences in the CMT and the RNFL thickness between the contralateral unaffected group and the normal control group(all P>0.05). The RPC density in the unilateral BRVO group increased compared with the contralateral unaffected group and decreased compared with the normal control group, but there was no statistically difference(all P>0.05). However, the RPC density in the contralateral unaffected group decreased compared with the normal control group(P<0.05). The RPC density in the unilateral BRVO group was not correlated with the CMT(P=0.960), but positively correlated with the RNFL thickness(r=0.401, P=0.014)and negatively correlated with the DAVD(r=-0.339, P=0.040).CONCLUSION: The RNFL thickened significantly and the RPC density did not change significantly in the optic disc area of BRVO patients. The RPC density is positively correlated with the RNFL thickness, indicating that the RNFL thickness can be used as a monitoring indicator to analyze and study the damage degree of the RPC density.

Background/Aims:
Dexamethasone (DEX) is a widely used exogenous therapeutic glucocorticoid in clinical settings. Its long-term use leads to many side effects. However, its effect on metabolic disorders in individuals on a high-fat diet (HFD) remains poorly understood.
Methods:
In this study, HFD-fed mice were intraperitoneally injected with DEX 2.5 mg/kg/day for 30 days. Lipid metabolism, adipocyte proliferation, and inflammation were assayed using typical approaches.
Results:
DEX increased the epididymal fat index and epididymal adipocyte size in HFD-fed mice. The number of epididymal adipocytes with diameters > 70 μm accounted for 0.5% of the cells in the control group, 30% of the cells in the DEX group, 19% of the cells in the HFD group, and 38% of all the cells in the D+H group. Adipocyte proliferation in the D+H group was inhibited by DEX treatment. Adipocyte enlargement in the D+H group was associated with increased the lipid accumulation but not the adipocyte proliferation. In contrast, the liver triglyceride and total cholesterol levels and their metabolism were downregulated by the same treatment, indicating the therapeutic potential of DEX for nonalcoholic fatty liver disease.
Conclusions
DEX synergizes with HFD to promote lipid deposition in adipose tissues. A high risk of obesity development in patients receiving HFD and DEX treatment is suggested.

ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine (TCM) syndrome elements and major adverse cardiovascular events (MACEs) in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor, and the patients were divided into an exposure group (integrated traditional Chinese and western medicine treatment group) and a non-exposure group (western medicine treatment group). The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third, sixth, and twelfth months, and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included, with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group, the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved (P<0.05). Compared with the non-exposure group, the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period (P<0.01) and significantly reduced blood stasis syndrome scores in the sixth month (P<0.05). In the remaining follow-up period, there was no statistically significant difference between the two groups. Compared with that of the non-exposure group, during the treatment period (the third month), the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant (P<0.05, P<0.01). At the end of the follow-up period, patients in the non-exposure group had a MACE probability of 6.90% (4/58), higher than 3.13% in the exposure group (4/58). Compared with patients with angina pectoris who used conventional medicine, patients administered with Tongxinluo Capsules had a relative risk(RR) of 0.45 [95%confidence interval(95%CI) 0.12-1.75, P=0.26]. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term, and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year, the incidence of MACE in the exposure group was lower than that in the non-exposure group.

ObjectiveTo explore the mechanism of the anti-cancer compound formula Feiyanning in inhibiting epithelial-mesenchymal transition (EMT) and invasion and metastasis of non-small cell lung cancer (NSCLC). MethodsCell proliferation and activity were assessed using the cell counting kit-8(CCK-8) assay to evaluate the effect of Feiyanning on the proliferation of A549 and H1299 cells. Wound healing and Transwell assays were conducted to examine Feiyanning's impact on the metastasis of A549 and H1299 cells. The effects of Feiyanning on EMT and the transforming growth factor-β1 (TGF-β1)/Smad signaling pathway proteins in A549 and H1299 cells were detected by Western blot. Exogenous TGF-β1 was used to induce EMT in A549 and H1299 cells. The effects of Feiyanning on TGF-β1-induced NSCLC cell metastasis, EMT, and the TGF-β1/Smad pathway proteins were assessed by wound healing assay, Transwell assay, and Western blot. In vivo, an A549 lung metastasis model was established via tail vein injection in nude mice. A total of 28 SPF male nude mice were randomly divided into four groups: Model (NC) group, Feiyanning low-dose (FYN1) group, Feiyanning high-dose (FYN2) group, and the positive control group (TGF-β receptor kinase inhibitor SB431542 group). The corresponding interventions were performed. After 40 days, the mice were euthanized, and lung metastases were analyzed. The expression of E-cadherin, N-cadherin, p-Smad2, and p-Smad3 in each group was detected by immunohistochemistry (IHC). ResultsAfter Feiyanning intervention, compared to the blank group, Feiyanning inhibited the proliferation of A549 and H1299 cells in a concentration-dependent manner (P<0.01). The metastasis ability of Feiyanning-treated cells was significantly decreased compared to the blank group (P<0.01). The expression of EMT marker proteins N-cadherin and zinc finger transcription factors (Zeb1, Snail, Slug) was significantly reduced in the Feiyanning groups compared to the blank group (P<0.05, P<0.01). The expression of p-Smad2/3, Smad2/3, TβRI, and TβRⅡ, key proteins in the TGF-β1/Smad signaling pathway, was also significantly decreased (P<0.01). In the TGF-β1-induced EMT model, compared to the TGF-β1 group, the cell metastasis ability in the Feiyanning groups was reduced (P<0.01), and the expression levels of N-cadherin, Zeb1, Snail, and Slug were significantly lower (P<0.01). The expression levels of p-Smad2/3, Smad2/3, TβRI, and TβRⅡ were also significantly reduced (P<0.01). In vivo results showed that compared to the model group, the number of lung metastases in the FYN1, FYN2, and SB431542 groups was reduced (P<0.01), and the range of cell infiltration was narrowed. Immunohistochemical results showed that compared to the model group, the expression of E-cadherin in the FYN1, FYN2, and SB431542 groups was increased (P<0.01), the expression of N-cadherin decreased (P<0.05, P<0.01), and the expression of p-Smad2 and p-Smad3, key proteins of the TGF-β1/Smad pathway, was reduced (P<0.01). ConclusionFeiyanning inhibits the invasion and metastasis of NSCLC cells and EMT. The mechanism is related to the inhibition of TGF-β1/Smad signaling pathway.
