ObjectiveTo identify the pathogen species responsible for the wilt disease of Tetradium ruticarpum in Chongqing, investigate there biological characteristics, and screen effective fungicides, so as to provide a theoretical basis for disease control in production. MethodsThe pathogen was isolated via the tissue culture method. Pathogenicity was verified according to Koch's postulates. The pathogen was identified based on morphological characteristics and multi-gene phylogenetic analysis. The mycelial growth rate method was used for biological characterization of the pathogen and fungicide screening. ResultsThe pathogen colonies were nearly circular with irregular edges, white, short, velvety aerial hyphae, and pale purple undersides. Macroconidia were colorless, sickle-shaped, with 3-5 septa, while microconidia were transparent, elliptical, aseptate or with 1-2 septa. Multi-gene phylogenetic analysis showed that the pathogen clustered in the same clade as Fusarium fujikuroi with 100% support, which, combined with morphological characteristics, identified the pathogen causing wilt of T. ruticarpum in Chongqing as F. fujikuroi. The optimal conditions for the mycelial growth of F. fujikuroi were mung bean agar (MBA) with glucose as the carbon source, beef extract and yeast powder as nitrogen sources, 28 ℃, pH 7.0, and alternating light/dark conditions. The optimal conditions for sporulation were potato dextrose agar (PDA) with glucose as the carbon source, beef extract as the nitrogen source, 28 ℃, pH 7.0, and complete darkness. Among chemical fungicides, phenazine-1-carboxylic acid exhibited the strongest inhibitory effect on F. fujikuroi. Shenqinmycin and tetramycin were the most effective bio-fungicides. ConclusionThis study is the first to report F. fujikuroi as the causal agent of wilt disease in T. rutaecarpa. The chemical fungicide phenazine-1-carboxylic acid and the bio-fungicides shenqinmycin and tetramycin showed strong inhibitory effects against F. fujikuroi.

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.

Electromagnetic fields can regulate the fundamental biological processes involved in bone remodeling. As a non-invasive physical therapy, electromagnetic fields with specific parameters have demonstrated therapeutic effects on bone remodeling diseases, such as fractures and osteoporosis. Electromagnetic fields can be generated by the movement of charged particles or induced by varying currents. Based on whether the strength and direction of the electric field change over time, electromagnetic fields can be classified into static and time-varying fields. The treatment of bone remodeling diseases with static magnetic fields primarily focuses on fractures, often using magnetic splints to immobilize the fracture site while studying the effects of static magnetic fields on bone healing. However, there has been relatively little research on the prevention and treatment of osteoporosis using static magnetic fields. Pulsed electromagnetic fields, a type of time-varying field, have been widely used in clinical studies for treating fractures, osteoporosis, and non-union. However, current clinical applications are limited to low-frequency, and research on the relationship between frequency and biological effects remains insufficient. We believe that different types of electromagnetic fields acting on bone can induce various “secondary physical quantities”, such as magnetism, force, electricity, acoustics, and thermal energy, which can stimulate bone cells either individually or simultaneously. Bone cells possess specific electromagnetic properties, and in a static magnetic field, the presence of a magnetic field gradient can exert a certain magnetism on the bone tissue, leading to observable effects. In a time-varying magnetic field, the charged particles within the bone experience varying Lorentz forces, causing vibrations and generating acoustic effects. Additionally, as the frequency of the time-varying field increases, induced currents or potentials can be generated within the bone, leading to electrical effects. When the frequency and power exceed a certain threshold, electromagnetic energy can be converted into thermal energy, producing thermal effects. In summary, external electromagnetic fields with different characteristics can generate multiple physical quantities within biological tissues, such as magnetic, electric, mechanical, acoustic, and thermal effects. These physical quantities may also interact and couple with each other, stimulating the biological tissues in a combined or composite manner, thereby producing biological effects. This understanding is key to elucidating the electromagnetic mechanisms of how electromagnetic fields influence biological tissues. In the study of electromagnetic fields for bone remodeling diseases, attention should be paid to the biological effects of bone remodeling under different electromagnetic wave characteristics. This includes exploring innovative electromagnetic source technologies applicable to bone remodeling, identifying safe and effective electromagnetic field parameters, and combining basic research with technological invention to develop scientifically grounded, advanced key technologies for innovative electromagnetic treatment devices targeting bone remodeling diseases. In conclusion, electromagnetic fields and multiple physical factors have the potential to prevent and treat bone remodeling diseases, and have significant application prospects.

Objective To investigate the probability and dosimetric risk factors of lung injury after sequential immune checkpoint inhibitors (ICIs) and thoracic radiotherapy. Methods A retrospective analysis was conducted on 139 patients who received sequential ICIs and thoracic radiotherapy in Xuzhou Cancer Hospital and Affiliated Hospital of Xuzhou Medical University between February 2020 and February 2024. The relationships of clinical factors and lung and heart volume dose parameters with grade ≥ 2 acute lung injury (ALI) in patients with thoracic tumors were studied using univariable (χ2 test, t test, nonparametric test) and multivariable (binary logistic regression analysis) methods. The thresholds of dosimetric risk factors were determined using the receiver operating characteristic curves. Clinical factors included age, gender, smoking history, type of ICIs, cycle of ICI application, and the interval between ICI application and thoracic radiotherapy. Dose parameters included total radiotherapy dose, single dose, planning target volume, maximum dose of planning target volume, average dose of planning target volume, total lung volume, heart volume, and the V5, V10, V15, V20, V25, V30, V35, and V40 of lung and heart. Results The incidence of grade ≥ 2 ALI in the included cases was 36% (50/139). The χ2 test did not find any statistically significant clinical factors. In the univariable and binary Logistic regression analysis, lung V15 and V20, heart V15 and V20, and lung volume were independent risk factors for the occurrence of grade ≥ 2 ALI in sequential ICIs and thoracic radiotherapy. The thresholds were 18.51% for lung V15, 14.43% for lung V20, 32.41% for heart V15, and 17.74% for heart V20. Conclusion For patients who are going to receive thoracic radiotherapy after ICIs, the thresholds of lung V15 and V20 and heart V15 and V20 in the radiotherapy plan are recommended to be less than 18.51%, 14.43%, 32.41%, and 17.74%, respectively, which can effectively reduce the occurrence of grade ≥ 2 ALI.

Atherosclerosis is a complex pathological condition resulting from lipid deposition, chronic inflammatory responses, and fibrosis, with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine (TCM) theory of accumulation syndrome, atherosclerosis can be classified under this category, with its pathogenesis involving phlegm, blood stasis, deficiency, and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking, supplementing, dispersing, dissipating", and divided into six stages based on the pathological progression, including the stage of accumulation before formation, the stage of accumulation already formed, the stage of nucleus accumulation, the stage of nucleus accumulation decay, the stage of nucleus accumulation consolidation, and the stage of severe stenosis of nucleus. At different stages, the intervention focuses on reinforcing healthy qi and consolidating the root, tonifying the kidneys and spleen, dispersing and removing turbidity, removing phlegm stagnation, promoting qi circulation, dispersing accumulations and removing stasis, attacking accumulation and expelling stasis, directing the turbid downward and dispersing accumulation, and treatment would be adjusted based on specific symptoms, which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.

ObjectiveTo evaluate the clinical efficacy and safety of Qidan Tangshen Granules (芪丹糖肾颗粒, QTG) in the treatment of early diabetic kidney disease (DKD) with qi deficiency, blood stasis, and kidney deficiency syndrome, and to explore its mechanism. MethodsA double-blind, double-simulated method was used to enroll 200 patients with early DKD and qi deficiency, blood stasis, and kidney deficiency syndrome. Patients were randomly assigned in a 1∶1 ratio to the treatment group (100 cases) and the control group (100 cases). The treatment group received QTG plus a valsartan capsule simulant, while the control group received valsartan capsules plus a QTG simulant, both for 12 weeks. The primary outcome was the urinary albumin-to-creatinine ratio (UACR). Secondary outcomes included estimated glomerular filtration rate (eGFR), fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG), glycated hemoglobin (HbA1c), and traditional Chinese medicine (TCM) syndrome scores (including individual symptom scores for fatigue, dull complexion, soreness and weakness of the waist and knees, headache and chest pain, irritability, spontaneous sweating, thirst and polydipsia, polyphagia, polyuria, numbness of the limbs, and the total TCM syndrome score). Oxidative stress markers including serum 8-hydroxy-2'-deoxyguanosine (8-OHDG), 3-nitrotyrosine (3-NT), and superoxide dismutase (SOD) were also assessed. Clinical efficacy and TCM syndrome efficacy were evaluated after treatment, and routine blood tests, urinalysis, and liver function tests were conducted and adverse reaction during the tria was recorded to assess safety. ResultsA total of 191 patients completed the study (95 in the treatment group and 96 in the control group). The treatment group showed significant reductions in UACR, FBG, PBG, and HbA1c levels after treatment (P<0.05 or P<0.01). The single TCM symptom scores except for polyphagia and total TCM syndrome scores significantly decreased (P<0.05 or P<0.01). Compared to the control group, the treatment group had signi-ficantly lower UACR, FBG, PBG levels, and total TCM syndrome scores, sinlge symptoms scores except for polyphagia and limb numbness (P<0.05 or P<0.01). Among 40 randomly selected patients (21 cases in the treatment group and 19 cases in the control group) for oxidative stress analysis, there were no significant differences in SOD, 3-NT, and 8-OHDG levels before and after treatment within or between groups (P>0.05). The overall effective rate in the treatment group was 64.2% (61/95) and 39.6% (38/96) in the control group, while the TCM syndrome efficacy rates were 80.0% (76/95) and 24.0% (23/96), respectively, with the treatment group showing superior efficacy (P<0.01). No significant differences were observed in routine blood tests, urinalysis, or liver function indices before and after treatment in either group (P>0.05). The incidence of adverse reactions was 8.4% (8/95) in the treatment group and 9.4% (9/96) in the control group, with no statistically significant difference (P>0.05). ConclusionQTG can effectively reduce UACR and blood glucose levels, alleviate clinical symptoms, and improve clinical efficacy in patients with early DKD with qi deficiency, blood stasis, and kidney deficiency syndrome. The treatment is well-tolerated and safe, with no significant impact on oxidative stress markers.

Objective:
To explore the impact of household tobacco smoke exposure on adolescents attempted smoking behavior, so as to provide a reference for tobacco control policy formulation and evaluation.
Methods:
From September to November 2023, a stratified cluster random sampling method was employed to select 7 841 middle and high school students from 10 monitoring sites (districts/counties) in Beijing for a questionnaire survey. Rao-Scott Chi square test was used to assess differences in proportions across subgroups, and complex sampling design based multivariate Logistic regression analysis was conducted to explore the influence of parental smoking and secondhand smoke (SHS) exposure at home on adolescents attempted smoking behavior.
Results:
About 47.17% of adolescents reported to have at least one parent smoked, with 42.36% reported of having only the father smoked, 0.73% reported of having only the mother smoked, and 4.08% reported of having both parents smoked. About 34.66% of middle and high school students were reported SHS exposure at home in the past 7 days, with 10.98%, 4.79% and 18.89% reported SHS exposure for 1-2, 3-4 and 5-7 days. Compared to adolescents with non smoking parents, those with a smoking father or both smoking parents had higher rates of attempted smoking [ OR (95% CI )=1.45(1.06-1.98), 3.73(2.18-6.37), P < 0.05 ]. Compared to adolescents without SHS exposure at home in the past 7 days, those exposed for 3-4 or 5- 7 days had higher rates of attempted smoking [ OR (95% CI )=2.21(1.27- 3.84 ), 2.46(1.58-3.83), P <0.01].
Conclusions
Household tobacco smoke exposure is associated with adolescent attempted smoking behavior. Parents should quit smoking and prohibit smoking at home to create a smoke free environment for adolescents.
