ObjectiveTo predict the mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer via network pharmacology and validate the prediction results in animal experiments. MethodsThe potential mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer was predicted by network pharmacology, liquid chromatography-mass spectrometry (LC-MS), and molecular docking methods. C57/BL6 mice were assigned into normal, model, cisplatin, and Shasheng Maidong Tang+cisplatin groups. In addition to the normal group, the remaining groups were injected subcutaneously with 0.2 mL of 1×107 cells·mL-1 Lewis lung cancer cells to establish the Lewis lung cancer model. The daily gavage dose of Shasheng Maidong Tang was 3.58 g·kg-1, and the concentration of cisplatin intraperitoneally injected on every other day was 2 mg·kg-1. Drugs were administered for 14 d. The changes in the tumor volume and the rate of tumor suppression were monitored, and the tumor histopathological changes were observed by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay was employed to measure the interleukin (IL)-6 and interferon (IFN)-γ levels in peripheral blood. Real-time PCR was performed to quantify the mRNA levels of Janus kinase 2 (JAK2), signal transducer and activator of transcription 1 (STAT1), and signal transducer and activator of transcription 3 (STAT3) in the tumor tissue of mice. Western blot was employed to determine the protein levels of JAK2, STAT3, B-cell lymphoma-2 (Bcl-2), cysteinyl aspartate-specific proteinase-3 (Caspase-3), and Pim-1 proto1 (PIM1) in the tumor tissue. Immunohistochemistry was employed to detect the expression of Bcl-2 and PIM1 in the tumor tissue. ResultsNetwork pharmacological predictions indicated that Shasheng Maidong Tang might enhance the efficacy of chemotherapy for lung cancer by regulating nitrogen metabolism, AGE-RAGE signaling pathway, cancer pathway, and JAK/STAT signaling pathway. The experimental results demonstrated that tumor volume in the cisplatin group and Shasheng Maidong Tang+cisplatin group was reduced compared with the model group, with statistically distinct differences observed on days 14, 17, 20 post modeling (P<0.05). Notably, the Shasheng Maidong Tang+cisplatin therapy further decreased tumor volume compared with the cisplatin group, showing marked reductions on days 17 and 20 (P<0.05), consistent with trends visualized in tumor volume comparison charts. The Shasheng Maidong Tang+cisplatin group exhibited higher tumor inhibition rate than the cisplatin group (P<0.05). Histopathological analysis via HE staining revealed that the tumors in the model group displayed frequent nuclear mitosis, densely arranged cells, hyperchromatic nuclei, and no necrosis. Cisplatin treatment induced partial necrosis and vacuolization, while the Shasheng Maidong Tang+cisplatin group exhibited extensive necrotic regions, maximal vacuolization, disarranged tumor cells, and minimal mitotic activity. Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed elevated level of IFN-γ (P<0.01) and declined level of IL-6 (P<0.01) in the peripheral blood. Compared with the cisplatin group, the Shasheng Maidong Tang+cisplatin group presented elevated level of IFN-γ (P<0.01) and lowered level of IL-6 (P<0.01) in the peripheral blood. Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin groups showed down-regulated mRNA levels of JAK2 and STAT3 (P<0.01) and up-regulated mRNA level STAT1 (P<0.01). Compared with the cisplatin group, the Shasheng Maidong Tang+cisplatin group presented down-regulated mRNA levels of JAK2 and STAT3 (P<0.01) and up-regulated mRNA level of STAT1 (P<0.01). Compared with the model group, the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed down-regulated protein levels of JAK2 (P<0.01), Bcl-2 (P<0.01), PIM1 (P<0.01), and STAT3 (P<0.05), and up-regulated protein level of Caspase-3 (P<0.01). Compared with the cisplatin group, Shasheng Maidong Tang+cisplatin group presented down-regulated protein levels of JAK2 (P<0.01), Bcl-2 (P<0.01), PIM1 (P<0.01), STAT3 (P<0.05), and up-regulated protein level of Caspase-3 (P<0.01). The Bcl-2 and PIM1 expression results obtained by immunohistochemistry were consistent with those of Western blot. ConclusionShasheng Maidong Tang may enhance the efficacy of chemotherapy in the mouse model of Lewis lung cancer by regulating the JAK2/STAT3 signaling pathway.

ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo investigate the effects of Shenxiong Huanglian Jiedu decoction on the clearance of amyloid β-protein (Aβ) and neuronal damage in the mouse model of Alzheimer's disease (AD). MethodsA total of 36 SPF-grade 2-month-old C57BL/6J mice were used in this study, and the modeling was performed by bilateral hippocampal injection of Aβ oligomers in C57BL/6J mice. The experiment was conducted with a blank group, a sham operation group, a model group, low- and high-dose (3.27,6.54 g·kg-1, respectively) Shenxiong Huanglian Jiedu decoction groups, and a positive control (donepezil hydrochloride, 0.65 mg·kg-1) group. At the end of the drug intervention, the learning and memory abilities and the activities of mice were evaluated by the Morris water maze and open field tests. Brain histopathology was examined by hematoxylin-eosin and Nissl staining. Additionally, in vivo imaging was employed to measure the metabolism of fluorescent Aβ in the cerebrospinal fluid, and staining of ionized calcium-binding adapter molecule-1 (Iba-1) was employed to assess microglial activation in the hippocampal tissue. Additionally, neurotrophin-3 (NT-3) and brain-derived neurotrophic factor (BDNF) levels in the brain tissue and serum were determined by the immunofluorescence assay and enzyme-linked immunosorbent assay. Western blot was conducted to determine the expression of inflammation and pathway-related proteins in the hippocampal tissue. ResultsCompared with the blank group and the sham operation group, the escape latency of the mice in the model group was prolonged, the platform residence time was shortened, the hippocampal tissue showed pathological manifestations such as neuronal pyknosis, Nissl body dissolution, and microglia activation. The metabolic rate of fluorescent Aβ through cerebrospinal fluid was slowed down, and the expression levels of BDNF, NT-3, and interleukin-10 (IL-10) in the hippocampus were significantly decreased (P<0.01). The expression levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and phosphorylated nuclear transcription factor-κB (p-NF-κB p65) in hippocampus were significantly increased (P<0.05, P<0.01). Compared with the model group, the escape latency of mice in the low and high dose groups of Chinese medicine and donepezil group was shortened, and the platform residence time was prolonged. Neuronal karyopyknosis, Nissl body dissolution and microglia activation in hippocampus were improved. Fluorescence Aβ was metabolized faster by cerebrospinal fluid. The expression of BDNF and NT-3 in hippocampus was increased (P<0.01), and the expression of TLR4, MyD88 and p-NF-κB p65 was significantly decreased (P<0.05, P<0.01). The expression of TNF-α in the hippocampus of the high-dose group was significantly decreased (P<0.05), and the expression of IL-10 was significantly increased (P<0.05). The expression of TNF-α, IL-6 and IL-1β in the hippocampus of the donepezil group was significantly decreased (P<0.05, P<0.01). ConclusionShenxiong Huanglian Jiedu decoction may mitigate neuronal damage and enhance cerebrospinal fluid flow in the mouse model of AD, thereby promoting the clearance of Aβ and improving the learning and memory abilities. These beneficial effects are likely mediated through the inhibition of microglial activation, reduction of inflammation, and modulation of the TLR4/MyD88/NF-κB signaling pathway.

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."

ObjectiveTo investigate the mechanisms by which the combination of berberine (BBR) and baicalin (BAI) ameliorates type 2 diabetes mellitus (T2DM) due to internal accumulation of dampness-heat from the perspectives of gut microbiota and metabolomics. MethodsAntibiotics were used to induce pseudo-sterile mice. Thirty pseudo-sterile mice were randomized into a normal fecal microbiota transplantation group (n=10) and a T2DM (syndrome of internal accumulation of dampness-heat) fecal microbiota transplantation group (n=20). The mice were then administrated with suspensions of fecal microbiota from healthy volunteers and a patient with T2DM due to internal accumulation of dampness-heat by gavage, respectively. Each mouse received 200 µL suspension every other day for a total of 15 times to reshape the gut microbiota. The T2DM model mice were then assigned into a model group (n=8) and a BBR-BAI group (n=11). BBR was administrated at a dose of 200 mg·kg-1, and BAI was administrated in a ratio of BBR-BAI 10∶1 based on preliminary research findings. The administration lasted for 8 consecutive weeks. Fasting blood glucose (FBG), glycated hemoglobin (HbA1c), insulin (INS), triglycerides (TG), total cholesterol (CHOL), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels were measured to evaluate the effects of the BBR-BAI combination on glucose and lipid metabolism and liver function in T2DM mice. Hematoxylin-eosin staining was employed to observe pathological changes in the colon tissue. The expression of claudin-1, zonula occludens-1 (ZO-1), and occludin in the colon tissue was determined by Western blot. Real-time quantitative polymerase chain reaction(Real-time PCR) was employed to assess the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the colon tissue. The fecal microbiota composition and differential metabolites were analyzed by 16S rRNA sequencing and ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (UPLC-Q-TOF-MS), respectively. ResultsThe BBR-BAI combination lowered the FBG, HbA1c, and INS levels (P<0.05, P<0.01) and alleviated insulin resistance (P<0.01) in T2DM mice. Additionally, BBR-BAI elevated the levels of ZO-1, occludin, and claudin-1 (P<0.05, P<0.01) and down-regulated the expression levels of TNF-α, IL-1β, and IL-6 in the colon (P<0.05, P<0.01). The results of 16S rRNA sequencing showed that BBR-BAI increased the relative abundance of Ligilactobacillus, Phascolarctobacterium, and Akkermansia (P<0.05), while significantly decreasing the relative abundance of Alistipes, Odoribacter, and Colidextribacter (P<0.05). UPLC-Q-TOF-MS identified 28 differential metabolites, which were primarily involved in arachidonic acid metabolism and α-linolenic acid metabolism. ConclusionBBR-BAI can ameliorate T2DM due to internal accumulation of dampness-heat by modulating the relative abundance of various bacterial genera in the gut microbiota and the expression of fecal metabolites.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

ObjectiveTo explore the possible mechanisms of Shujin Jiannao Formula (舒筋健脑方) for cerebral palsy. MethodsThirty 7-day-old SD rats were randomly divided into normal group, model group, and Shujin Jiannao Formula group, with 10 rats in each group. The model group and Shujin Jiannao Formula group established a cerebral palsy model by the classic Rice-Vannucci method. After successful modeling, rats in Shujin Jiannao Formula group were given Shujin Jiannao Formula 16 g/(kg·d) by gavage, while the normal group and model group were given normal saline 10 ml/(kg·d) by gavage once a day. After one week of intervention, the rats' body weight was measured, and Zea-Longa scores, the righting reflex test, and the hindlimb suspension test were conducted for assessment; hematoxylin-eosin (HE) staining and Nissl staining were used to observe pathological changes in brain tissue, and the number of Nissl-positive neurons was counted; enzyme-linked immunosorbent assay (ELISA) was employed to measure levels of inflammatory cytokines in the brain tissue, specifically interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α); immunofluorescence was used to detect the expression levels of neurofilament protein 200 (NF200) and myelin basic protein (MBP) in brain tissue; Western Blot analysis was conducted to determine the protein levels of phosphoinositide 3-kinase (PI3K), protein kinase B (Akt/PKB/Rac), and mammalian target of rapamycin (mTOR) in brain tissue. ResultsCompared with the normal group, rats in the model group showed significantly higher Zea-Longa scores and lower scores in the hindlimb suspension test (P<0.01); pathological findings revealed loose structure in the cerebral cortex, hippocampal atrophy, and neuronal damage in brain tissue. Levels of IL-1β and TNF-α elevated, and the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region reduced, and immunofluorescence intensity of NF200 and MBP, as well as protein expression levels of PI3K and mTOR, significantly decreased (P<0.05 or P<0.01). Compared with the model group, rats in Shujin Jiannao Formula group showed decreased Zea-Longa scores and increased hindlimb suspension test scores (P<0.05); pathological damage in brain tissue alleviated, levels of IL-1β and TNF-α reduced, the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region increased, and the immunofluorescence intensity of NF200 and MBP, as well as the protein levels of PI3K and mTOR, significantly elevated (P<0.05 or P<0.01). There were no statistically significant differences among the groups in body weight, body-turning time, or AKT protein levels in brain tissue (P>0.05). ConclusionShujin Jiannao Formula can improve the neurological function of rats with cerebral palsy, exert neurorestorative effects, and its mechanism of action may be related to the reduction of inflammatory response in brain tissue and the activation of the PI3K/AKT/mTOR signaling pathway.
