ObjectiveTo investigate the mechanism of action of Kaixinsan in the treatment of Alzheimer's disease (AD) based on network pharmacology, molecular docking, and animal experimental validation. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and the Encyclopedia of Traditional Chinese Medicine(ETCM) databases were used to obtain the active ingredients and targets of Kaixinsan. GeneCards, Online Mendelian Inheritance in Man(OMIM), TTD, PharmGKB, and DrugBank databases were used to obtain the relevant targets of AD. The intersection (common targets) of the active ingredient targets of Kaixinsan and the relevant targets of AD was taken, and the network interaction analysis of the common targets was carried out in the STRING database to construct a protein-protein interaction(PPI) network. The CytoNCA plugin within Cytoscape was used to screen out the core targets, and the Metascape platform was used to perform gene ontology(GO) functional enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis. The “drug-active ingredient-target” interaction network was constructed with the help of Cytoscape 3.8.2, and AutoDock Vina was used for molecular docking. Scopolamine (SCOP) was utilized for modeling and injected intraperitoneally once daily. Thirty-two male C57/BL6 mice were randomly divided into blank control (CON) group (0.9% NaCl, n=8), model (SCOP) group (3 mg·kg-1·d-1, n=8), positive control group (3 mg·kg-1·d-1 of SCOP+3 mg·kg-1·d-1 of Donepezil, n=8), and Kaixinsan group (3 mg·kg-1·d-1 of SCOP+6.5 g·kg-1·d-1 of Kaixinsan, n=8). Mice in each group were administered with 0.9% NaCl, Kaixinsan, or Donepezil by gavage twice a day for 14 days. Morris water maze experiment was used to observe the learning memory ability of mice. Hematoxylin-eosin (HE) staining method was used to observe the pathological changes in the CA1 area of the mouse hippocampus. Enzyme linked immunosorbent assay(ELISA) was used to determine the serum acetylcholine (ACh) and acetylcholinesterase (AChE) contents of mice. Western blot method was used to detect the protein expression levels of signal transducer and activator of transcription 3(STAT3) and nuclear transcription factor(NF)-κB p65 in the hippocampus of mice. ResultsA total of 73 active ingredients of Kaixinsan were obtained, and 578 potential targets (common targets) of Kaixinsan for the treatment of AD were screened out. Key active ingredients included kaempferol, gijugliflozin, etc.. Potential core targets were STAT3, NF-κB p65, et al. GO functional enrichment analysis obtained 3 124 biological functions, 254 cellular building blocks, and 461 molecular functions. KEGG pathway enrichment obtained 248 pathways, mainly involving cancer-related pathways, TRP pathway, cyclic adenosine monophosphate(cAMP) pathway, and NF-κB pathway. Molecular docking showed that the binding of the key active ingredients to the target targets was more stable. Morris water maze experiment indicated that Kaixinsan could improve the learning memory ability of SCOP-induced mice. HE staining and ELISA results showed that Kaixinsan had an ameliorating effect on central nerve injury in mice. Western blot test indicated that Kaixinsan had a down-regulating effect on the levels of NF-κB p65 phosphorylation and STAT3 phosphorylation in the hippocampal tissue of mice in the SCOP model. ConclusionKaixinsan can improve the cognitive impairment function in SCOP model mice and may reduce hippocampal neuronal damage and thus play a therapeutic role in the treatment of AD by regulating NF-κB p65, STAT3, and other targets involved in the NF-κB signaling pathway.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

Objective:To explore the distribution of allergen-specific IgE (sIgE) for children with atopic dermatitis in Tianjin City and provide the evidences of clinical diagnosis and treatment.Methods:A retrospective cross-sectional study was conducted to analyze the children who were suspected of atopic dermatitis and tested for serum sIgE in the Tianjin Children′s Hospital from March 2021 to February 2023. Using first detection results only, a total of 1 841 serum samples were tested for twenty common allergens. The method was the enzyme-linked immune capture assay. The allergen epidemiological characteristics were statistically analyzed by Chi square test based on the children′s characteristics and factors such as different sexes, ages and seasons by the mass data.Results:Among the 1 841 cases, the results showed that 1 247 (67.73%) were sensitized to at least 1 allergen-sIgE, comprising to 49.86% (918/1 841) to food allergen-sIgE and 47.96% (883/1 841) to aeroallergen-sIgE. The top three food allergens-sIgE were egg 32.10% (591/1 841), milk 25.91% (477/1 841) and wheat flour 14.61% (269/1 841); the top three positive rates of aeroallergens-sIgE were house dust 24.33% (448/1 841), alternaria 20.59% (379/1 841) and dermatophagoides farinae 14.83% (273/1 841). The positive rates of food allergens-sIgE were the highest in the 1-3 years old group (64.11%, 434/677) ( χ2=122.854, P<0.001), while the positive rates of aeroallergens-sIgE were higher in the 11-14 years old group (71.26%, 62/87) ( χ2=134.968, P<0.001). No seasonal difference was revealed in the overall positive rate of food allergen-sIgE and aeroallergen-sIgE ( χ2=4.047, P=0.256; χ2=7.549, P=0.056). The positive rates of soybean-sIgE and milk-sIgE were the highest in summer ( χ2=11.329, P=0.010; χ2=28.720 , P<0.001), whereas alternaria-sIgE and mugwort-sIgE were the highest in summer and autumn, respectively ( χ2=8.462, P=0.037; χ2=10.641 , P=0.014). Among the 1 841 cases, 32.21% were sensitized to three or more allergens-sIgE. The sIgE concentration levels of egg, milk and house dust were mainly level 1 to 2, and the proportions of level 3 and above were all under 15%; although the positive rates of crab, shrimp, and peanut were low, the proportions of grade 3 and above were all beyond 30%. Children sensitized to alternaria, dermatophagoides farinae, mugwort, and cat dander had higher sIgE concentration levels, which were 68.07%, 49.45%, 56.57% and 47.83% respectively. Conclusions:This study can reflect the epidemic characteristics of allergen-sIgE in children with atopic dermatitis in Tianjin region to a certain extent. Allergen-sIgE positivity in patients differed by age, and there were seasonal differences and grade distribution differences in the positive rates of some allergens-sIgE. It is necessary to reasonably avoid the high-risk allergens according to the epidemiological characteristics and clinical symptoms, which provide valuable information for the prevention, diagnosis and treatment of atopic dermatitis.
