Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Clinical pharmacology is an important discipline that bridges clinical medicine and pharmacology. In the teaching practice, it is necessary to keep up with educational reform and adopt the seminar teaching method combined with case-based learning (CBL), so as to practically improve the benefits of both "teaching" and "learning". The teaching of ideology and politics in the curriculum is the key to cultivate students' high sense of responsibility and noble medical ethics, and realize the goal of moral education. At present, in the teaching of clinical pharmacology of antineoplastic drugs, there are problems such as students' weak basic knowledge of oncology pharmacology, separation of "teaching" and "learning" due to the traditional teaching method, outdated teaching materials, and low motivation of students. Therefore, this paper takes this part of the course teaching as an example to initially explore the role of the innovative model of "Seminar-CBL-Ideological and Political Education " in the teaching practice of clinical pharmacology, with the hope of stimulating the students' interest in learning, cultivating students' correct outlook on the world, life, and values, achieving the goals of "teaching" and "learning", and providing reference for optimizing clinical pharmacology education.

Objective To explore the clinical efficacy of arc-edge needle therapy based on Zaodian theory in the treatment of refractory tennis elbow.Methods 64 patients with refractory tennis elbow were collected and randomly divided into a control group and an observation group using a random number table method.Among them,32 cases in the control group were treated with local pain point injection.32 patients in the observation group were treated with arc-edge needle therapy once a week,with two treatments per group.The Number rating scale(NRS)Mayo,elbow joint performance score(MEPS)and Disabilities of the arm,shoulder and hand(DASH)score were recorded and compared between the two groups before treatment and at 1,2,4 and 24 weeks of follow-up after treatment,disease efficacy score(WDES)at 24 weeks of follow-up.Results During the treat-ment process,neither group of patients experienced serious adverse reactions.At each stage after treatment,two groups of NRS MEPS,DASH,and WDES at 24 weeks of follow-up all improved compared to before treatment.After one week of treatment,there was no statistically significant difference in NRS scores between the two groups(P>0.05).At follow-up visits at weeks 2,4,and 24,the NRS scores in the observation group were lower than those in the control group.After 1,2,4,and 24 weeks of follow-up after treatment,the DASH score was lower in the observation group than in the control group,and the MEPS score was higher in the observation group than in the control group,with statistically significant differences(P<0.05).After 24 weeks of treatment,the WDES of the observation group was better than that of the control group,and the difference was statistically significant(P<0.05).Conclusion Local pain point injection and arc-edge Zaodian release can alleviate pain and improve elbow joint function in the early stage of refractory tennis elbow.However,the long-term effect of local pain point injection treatment is not good,and the treatment effect of the observation group gradually improves.

Objective To screen mitochondria-related genes in Crohn's disease (CD) based on the Gene Expression Omnibus (GEO) database, construct an artificial neural network diagnostic model and evaluate its performance. Methods The CD-related datasets GSE186582 and GSE102133 were downloaded from the GEO database for differential expression genes (DEGs) screening. The intersection of DEGs and mitochondrial genes from the MitoCarta 3.0 database was obtained. Least absolute shrinkage and selection operator regression and random forest algorithms were used to identify CD-specific genes and construct an artificial neural network diagnostic model. The model was further validated by the validation set GSE95095, and the diagnostic performance was evaluated by the area under the curve (AUC) of the receiver operating characteristic curve. The immune cell infiltration in CD was assessed by the CIBERSORT algorithm, and the relationship between biomarkers and infiltrated immune cells was investigated. Results A total of 551 DEGs were obtained, including 275 upregulated and 276 downregulated genes. There were 20 mitochondria-related genes associated with CD. A total of 9 mitochondria-related feature genes (SOD2, MTHFD2, BPHL, PXMP2, RMND1, AGXT2, MAOA, HMGCS2, MAOB) were screened by two machine learning algorithms. An artificial neural network diagnostic model was constructed by the selected feature genes. The values of AUC of the model in the training and validation groups were 0.956 and 0.736 respectively. Immune cell infiltration analysis showed that the feature genes were associated with resting memory CD4⁺ T cells, activated memory CD4⁺ T cells, activated dendritic cells, neutrophils, and CD8⁺ T cells. Conclusion The artificial neural network diagnostic model for CD based on 9 mitochondrial genes has good predictive performance.

Objective To construct a prognostic prediction model for hepatocellular carcinoma (HCC) based on immune and metabolism related genes, analyze the prognostic immune response of HCC patients, and screen potential drugs for HCC treatment through drug sensitivity analysis. Methods HCC expression profiling and clinical data were obtained from The Cancer Genome Atlas (TCGA) database, and a list of immune-related genes was obtained from the Immport database; the Perl language was used to extract metabolism-related pathway gene sets from the Molecular Signatures Database(MSig DB), and co-expression related genes were found through differential analysis and co-expression analysis; the univariate Cox regression analysis, the least absolute shrinkage and selection operator (LASSO) regression analysis, and multivariate Cox regression analysis were used to screen prognosis-related genes and construct a risk prognosis model for HCC, and risk scores for all HCC samples were calculated. Using the median risk score as the critical value, the reliability of the prognostic model was evaluated through risk curves, Kaplan-Meier survival analysis, receiver operating characteristic (ROC) curves, independent prognostic analysis, and Nomograms. The correlations between risk scores and pathway enrichment analysis as well as immune cell infiltration were analyzed. Drug sensitivity analysis was used to identify potential therapeutic drugs for HCC. Results Five immune and metabolic genes with independent prognostic value were obtained, and a prognostic model based on immune and metabolic genes was constructed. Survival analysis showed that in the total dataset, training group and validation group, the survival rate of the low-risk group was significantly higher than that ofthe high-risk group (P < 0.05). The areas under the ROC curves of the prognostic model for the training group at 1, 3 and 5 years were 0.780, 0.699 and 0.706 respectively. Cox regression analysis showed that grading and risk score could be used as independent prognostic factors for HCC (P < 0.05), with a concordance index of 0.734 (95%CI, 0.669 to 0.798), indicating good model performance. Immune cell infiltration results showed significant differences in resting NK cells, monocytes, M0 macrophages, and M1 macrophages between the high-risk and low-risk groups (P < 0.05). Drug sensitivity analysis screened 12 drugs that may have potential therapeutic effects in HCC patients (P < 0.01). Conclusion The prognostic model of HCC based on five immune and metabolic genes has good predictive performance, and can be used as a new indicator for prognosis evaluation; the 12 drugs screened out have potential efficacy for HCC.

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group， model group， positive control group （27 mg/kg allopurinol+0.27 mg/kg colchicine）， Tongfeng li’an capsules low- dose， medium-dose and high-dose groups （2.2， 4.5， 9.0 g/kg）， with 10 rats in each group. Except for normal group， gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically， and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling， serum level of interleukin-1β （IL-1β） and protein expressions of nuclear factor kappa-B （NF-κB） in synovial tissue were detected， and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules （62.5， 125， 250 μg/mL） were given， the levels of nitric oxide （NO）， reactive oxygen species （ROS） and IL-1β in the cells and protein expression of NF-κB were detected， and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group， the swelling degree of the ankle joint， serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group （P＜0.05）； pathological changes such as synovial hyperplasia， edema， vascular congestion， capillary hyperplasia， and increased inflammatory cells were observed. Compared with model group， the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group （P＜0.05）， and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups （P＜0.05）； synovial hyperplasia of the ankle joint improved， and the infiltration of inflammatory cells 2019BS044） decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO， ROS and IL-1β and protein expression of NF-κB（P＜0.01）， and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis， and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.
