Intervertebral disc degeneration (IVDD) is the predominant pathological contributor to chronic low back pain, a pervasive musculoskeletal condition affecting over 630 million people globally and imposing tremendous socioeconomic and public health burdens. The etiopathogenesis of IVDD is remarkably complex and multifactorial, involving intricate crosstalk among chronic inflammatory responses, extracellular matrix (ECM) catabolism, cellular senescence, aberrant programmed cell death (including apoptosis, pyroptosis, and ferroptosis), mitochondrial dysfunction, and oxidative damage. Compelling evidence indicates that the inflammatory microenvironment acts as a decisive driving force throughout the entire degenerative course of IVDD. Among the diverse inflammatory mediators, interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) serve as core pro-inflammatory cytokines that initiate and perpetuate the degenerative cascade. These two pivotal cytokines collectively activate an array of canonical intracellular signaling pathways, including nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3) inflammasome, and the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) cascade. Such interconnected signaling networks trigger a self-reinforcing positive feedback loop, which exacerbates inflammatory reactions, disrupts the anabolic-catabolic homeostasis of the ECM, promotes oxidative stress and mitochondrial injury, induces multiple forms of disc cell death, and ultimately leads to progressive structural collapse and functional deterioration of the intervertebral disc. Conventional therapeutic strategies, dominated by nonsteroidal anti-inflammatory drugs and surgical interventions, are limited by systemic adverse reactions, suboptimal long-term efficacy, and the risk of adjacent segment degeneration. In contrast, traditional Chinese medicine (TCM) exhibits prominent advantages in the prevention and treatment of IVDD by virtue of its holistic regulation, syndrome differentiation, and multi-component, multi-target, multi-pathway pharmacological properties. This review systematically elucidates the molecular mechanisms by which inflammation-associated signaling pathways modulate disc cell fate and ECM metabolic homeostasis, and comprehensively summarizes the experimental progress over the past five years on TCM monomers and compound formulas for intervening in IVDD. Accumulating studies have confirmed that numerous natural active ingredients isolated from herbal medicines (ferulic acid, mangiferin, paeonol, astragaloside IV) and representative TCM compound prescriptions (Bushen Huoxue Formula, Shensuitongzhi Formula, Fuzi Decoction) exert synergistic protective effects by coordinately targeting core signaling hubs. These TCM agents demonstrate potent anti-inflammatory, antioxidant, anti-apoptotic, anti-pyroptotic, anti-ferroptotic, ECM-protective, and autophagy-regulating bioactivities, thereby effectively decelerating the pathological progression of IVDD. Despite remarkable progress, current investigations are still confronted by several critical limitations. Most studies are restricted to validating the regulatory effects of single TCM components on individual signaling pathways, leaving the systematic, dynamic, and synergistic mechanisms of TCM compound formulas within multi-pathway regulatory networks largely unexplored. Furthermore, clinical translation of TCM is severely hampered by the lack of efficient targeted drug delivery systems, unclear pharmacokinetic profiles, suboptimal local bioavailability, and incomplete long-term safety assessments. Therefore, future research should adopt an interdisciplinary paradigm integrating multi-omics technologies, artificial intelligence, organoid models, and organ-on-chip systems to systematically decipher the scientific basis of TCM against IVDD. Concurrently, the development of intelligent, site-specific delivery systems (hydrogels, nanoparticles, exosome-based carriers) is urgently needed to enhance the local accumulation and sustained release of TCM ingredients. By deepening mechanistic exploration and accelerating translational research, TCM is expected to evolve into safe, effective, and personalized precision therapeutic regimens for IVDD, offering novel and reliable solutions for the clinical management of chronic low back pain.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE To analyze the potential adverse drug interactions based on pharmacokinetics(PK-pADIs)of gefitinib,and establish its corresponding prescription review rules.METHODS Outpatient prescriptions of gefitinib combination therapy in our hospital from January 1,2022 to November 30,2024 were collected through rational drug software system.PK-pADIs present in the prescriptions were identified based on the Drugs.com? drug interactions database.The specific combination drugs and cases of PK-pADIs were statistically analyzed,and prescription review rules were established according to the severity classification of PK-pADIs.RESULTS&CONCLUSIONS A total of 217 prescriptions of gefitinib combination therapy were enrolled.Among them,28 prescriptions(12.90%),involving a total of 28 patients,had 29 cases of PK-pADIs,with respiratory medicine prescriptions(22 prescriptions)being the main type.The combination drugs included proton pump inhibitors(13 cases),strong cytochrome P450 3A4(CYP3A4)inhibitors(7 cases),H2 receptor antagonists(4 cases),CYP3A4 inducers(3 cases),and CYP2D6 substrates(2 cases).The severity classifications for these interactions were severe,moderate,severe,moderate and moderate,respectively.Based on the above severity classification of PK-pADIs,four prescription review rules had been established as follows:when gefitinib was combined with acid-suppressing drugs,it should be subject to"manual review";when gefitinib was combined with dexamethasone,metoprolol,or strong CYP3A4 inhibitors,an"alert"should be triggered,and the physician should be informed via an alert box to strengthen the monitoring of relevant indicators.Clinical pharmacists need to conduct in-depth training on knowledge related to gefitinib drug interactions in key clinical departments such as respiratory medicine.They should strengthen the monitoring and guidance of rational drug use for patients who are on long-term gefitinib therapy,and promptly identify and intervene in PK-pADIs,thereby enhancing the rationality,safety,and effectiveness of clinical drug use.

Objective To analyze the effects of left bundle branch area pacing(LBBaP)on atrial fibrillation occurrence after dual-chamber pacemaker implantation.Methods The medical records of 87 patients who underwent dual-chamber pacemaker implantation at People's Hospital between May 2021 and September 2022 were retrospectively analyzed.According to different implantation methods,the patients were divided into an observation group(n=45)and a control group(n=42).The control group received traditional right ventricular pacing(RVP),while the observation group received LBBaP.Serum N-terminal pro B-type natriuretic peptide(NT-proBNP),QRS onset-to-end duration(QRSd),echocardiographic parameters,cardiac pacing parameters,complications,atrial high-rate events,and atrial fibrillation incidence were compared between the two groups.Results Twelve months after surgery,serum NT-proBNP levels in the observation group were significantly lower than those in the control group(P＜0.05),and QRS duration(QRSd)was shorter in the observation group than in the control group(P＜0.05).There were no significant differences in left ventricular ejection fraction(LVEF)or left ventricular end-systolic diameter(LVESD)between the two groups at 12 months postoperatively(P＞0.05).Left atrial diameter(LAD)was smaller in the observation group than in the control group at 12 months postoperatively(P＜0.05).No significant differences were observed in sensing levels or the proportion of cardiac pacing between the two groups(P＞0.05).However,the proportion of ventricular pacing was higher in the observation group than in the control group(P＜0.05).Intraoperatively and at 12 months postoperatively,impedance levels were lower in the observation group than in the control group(P＜0.05),while threshold values were higher in the observation group(P＜0.05).Total complication rates did not differ significantly between the two groups(P＞0.05).At 12 months postoperatively,the incidence of atrial fibrillation was similar between the two groups(P＞0.05),but the incidence of atrial high-rate events was lower in the observation group than in the control group(P＜0.05).At 24 months postoperatively,both the incidence of atrial high-rate events and atrial fibrillation were lower in the observation group than in the control group(P＜0.05).Conclusion Compared with traditional RVP implantation,LBBaP implantation can significantly improve left heart function,provide more stable pacing parameters,and reduce the risk of long-term atrial high-rate events and atrial fibrillation.The risk of complications is similar for both groups,but LBBaP implantation increases the pacing threshold.

Objective To analyze the effect of dronedarone and propafenone in preventing postoperative recurrence in patients with atrial fibrillation(AF)and to discuss its influence on inflammatory response and myocardial injury.Methods A total of 113 patients with AF,who were admitted to the Qiandongnan People's Hospital of China from July 2022 to March 2024,were enrolled in this study.By using random number table method,the patients were divided into control group(n=56)and study group(n=57).All patients received circumpulmonary vein electrical isolation.After treatment,the patients of control group were given propafenone orally for three months,while the patients of study group received dronedarone orally for three months.Both the preoperative and postoperative 3-month inflammatory response indicators including hypersensitive C-reactive protein(Hs-CRP),leucolipin,nucleotide-bound oligomeric domain-like receptor protein 3(NLRP3)inflammasome,and tumor necrosis factor α(TNF-α),the echocardiographic indicators including left atrial maximum volume(LAMV),left ventricular end-systolic diameter(LVESD),and left ventricular ejection fraction(LVEF),the myocardial injury markers including creatine kinase(CK),cardiac troponin I(cTn I),the central nervous specific protein β(S100β),the creatine kinase isoenzyme(CK-MB),the adverse reactions,and the recurrence of AF were compared between the two groups.Results At 3 months after treatment,the serum levels of hs-CRP,leucolipin,NLRP3 inflammasome and TNF-α were decreased in both groups(all P＜0.01),which in the study group were obviously lower than those in the control group(all P＜0.001);the levels of LAMV and LVESD were decreased in both groups(both P＜0.01),which in the study group were remarkably lower than those in the control group(both P＜0.001);the level of LVEF was increased in both groups(P＜0.01),which in the study group was significantly higher than that in the control group(P＜0.001);the levels of CK,cTn I,S100β,and CK-MB were decreased in both groups(all P＜0.01),which in the study group were strikingly lower than those in the control group(all P＜0.001).The incidence of adverse drug reactions in control group and in the study group was 5.36％(3/56)and 7.02％(4/57 cases)respectively,and the difference was not statistically significant(P＞0.05).Within 3 months after treatment,the recurrence rate in the study group was 5.26％(3/57),which was lower than 19.64％(11/56)in the control group,and the difference was statistically significant(P＜0.05).Conclusion Compared with propafenone,the use of dronedarone after circumferential pulmonary vein electrical isolation in patients with AF can improve the cardiac functions,reduce myocardial injury and inflammatory responses,and lower the risk of postoperative recurrence of AF.

Objective This study aimed to provide an effective scientific basis for prevention and control of cockroaches on aircrafts by identifying cockroach-carried pathogens,and assess the insecticidal efficacy of gel bait mediated cockroach control on aircrafts,to provide technical guidance for aircraft disinsection.Methods Cassette-trapping was used to trap cockroaches,and the carried pathogens were detected using bacterial cultivation techniques.The gel bait mediated killing rate was calculated after 1,7,and 30 d by field application of gel bait.Results A total of 411 cockroaches were captured,and all were identified as Blattella germanica.26 strains of pathogenic bacteria were isolated from the trapped cockroaches.The killing rates of cockroaches were 58.8％-96.3％with 1-30 day application of gel bait.Statistically significant differences were observed in cockroach killing rates on different days(χ2=58.95,P<0.01).Conclusions B.germanica carry a large variety of pathogenic bacteria and opportunistic pathogens and are thus important infectious disease carriers.Gel bait agents have proven to be very effective against cockroaches on aircrafts.

Objective To investigate the density,species composition,and seasonal prevalence of domestic rodents in different habitats within Lanzhou garrisons,providing basic information for rodent prevention and control.Methods A total of 12 monitoring sites were sampled across urban,suburban,and rural residential areas from 2014 to 2022.Rodent density was monitored using the night-trapping method in the middle of odd-numbered months.Results From 2014 to 2022,346 domestic rodents were captured using 122 035 effective traps,with an average domestic rodent density of 0.28％.The highest domestic rodent density was 0.63％in 2016,and the lowest was 0.07％in 2020,showing significant differences across years,with an overall trend of initially decreasing and then increasing(χ2=136.555,P<0.001).The dominant species was Rattus norvegicus,accounting for 83.24％of the total rodents captured.Rattus norvegicus accounted for a relatively high proportion across different years,with a statistically significant difference in species composition(χ2=20.931,P<0.05).Rodent densities and species composition also varied significantly among the monitored habitats(P<0.001),with the highest densities observed in rural residential areas and the lowest in urban areas.Seasonal variation in rodent densities showed a bimodal pattern,with smaller peaks in January or March and a larger peak in July.Conclusions Domestic rodent density in Lanzhou garrisons has shown an upward trend in the past few years.Rodent control measures should focus on barracks in rural residential areas,with targeted interventions to reduce the risk of rodent-borne diseases.

This study aims to explore the medication rules and mechanisms of treating chronic renal failure(CRF) by Jinling medical school based on data mining, network pharmacology, and experimental validation systematically and deeply. Firstly, the study selected the papers published by the inherited clinicians in Jinling medical school in Chinese journals using the subject headings named "traditional Chinese medicine(TCM) + chronic renal failure", "TCM + chronic renal inefficiency", or "TCM + consumptive disease" in China National Knowledge Infrastructure, Wanfang, and VIP Chinese Science and Technology Periodical Database and screened TCM formulas for treating CRF according to inclusion and exclusion criteria. The study analyzed the frequency of use of single TCM and the four properties, five tastes, channel tropism, and efficacy of TCM used with high frequency and performed association rule and clustering analysis, respectively. As a result, a total of 215 TCM formulas and 235 different single TCM were screened, respectively. The TCM used with high frequency included Astragali Radix, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Poria, and Atractylodis Macrocephalae Rhizoma(top 5). The single TCM characterized by "cold properties, sweet flavor, and restoring spleen channel" and the TCM with the efficacy of tonifying deficiency had the highest frequency of use, respectively. Then, the TCM with the rules of "blood-activating and stasis-removing" and "diuretic and dampness-penetrating" appeared. In addition, the core combination of TCM [(Hexin Formula, HXF)] included "Astragali Radix, Rhei Radix et Rhizoma, Poria, Salviae Miltiorrhizae Radix, and Angelicae Sinensis Radix". The network pharmacology analysis showed that HXF had 91 active compounds and 250 corresponding protein targets including prostaglandin-endoperoxide synthase 2(PTGS2), PTGS1, sodium voltage-gated channel alpha subunit 5(SCN5A), cholinergic receptor muscarinic 1(CHRM1), and heat shock protein 90 alpha family class A member 1(HSP90AA1)(top 5). Gene Ontology(GO) function analysis revealed that the core targets of HXF predominantly affected biological processes, cellular components, and molecular functions such as positive regulation of transcription by ribonucleic acid polymerase Ⅱ and DNA template transcription, formation of cytosol, nucleus, and plasma membrane, and identical protein binding and enzyme binding. Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis revealed that CRF-related genes were involved in a variety of signaling pathways and cellular metabolic pathways, primarily involving "phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt) pathway" and "advanced glycation end products-receptor for advanced glycation end products". Molecular docking results showed that the active components in HXF such as isomucronulatol 7-O-glucoside, betulinic acid, sitosterol, and przewaquinone B might be crucial in the treatment of CRF. Finally, a modified rat model with renal failure induced by adenine was used, and the in vivo experimental confirmation was performed based on the above-mentioned predictions. The results verify that HXF can regulate mitochondrial autophagy in the kidneys and the PI3K-Akt-mammalian target of rapamycin(mTOR) signaling pathway activation at upstream, so as to alleviate renal tubulointerstitial fibrosis and then delay the progression of CRF.

The interactions between microorganisms and medicinal plants are crucial to the quality improvement of medicinal plants. Medicinal plants attract microorganisms to colonize by secreting specific compounds and provide niche and nutrient support for these microorganisms, with a symbiotic network formed. These microorganisms grow in the rhizosphere, phyllosphere, and endophytic tissues of plants and significantly improve the growth performance and medicinal component accumulation of medicinal plants by promoting nutrient uptake, enhancing disease resistance, and regulating the synthesis of secondary metabolites. Microorganisms are also widely used in the ecological planting of medicinal plants, and the growth conditions of medicinal plants are optimized by simulating the microbial effects in the natural environment. The interactions between microorganisms and medicinal plants not only significantly improve the yield and quality of medicinal plants but also enhance their geoherbalism, which is in line with the concept of green agriculture and eco-friendly development. This study reviewed the research results on the interactions between medicinal plants and microorganisms in recent years and focused on the analysis of the great potential of microorganisms in optimizing the growth environment of medicinal plants, regulating the accumulation of secondary metabolites, inducing systemic resistance, and promoting the ecological planting of medicinal plants. It provides a scientific basis for the research on the interactions between medicinal plants and microorganisms, the research and development of microbial agents, and the application of microorganisms in the ecological planting of medicinal plants and is of great significance for the quality improvement of medicinal plants and the green and sustainable development of TCM resources.
