Objective To compare the dosimetric differences, plan complexity, verification pass rate, and execution efficiency of volumetric modulated arc therapy (VMAT) plans designed for post-mastectomy radiotherapy of breast cancer using Halcyon 2.0 and VitalBeam accelerators in flattening filter-free mode. Methods A retrospective analysis was conducted on imaging data from 87 female breast cancer patients aged 29 to 75 (49.9 ± 9.9) years who underwent modified radical mastectomy followed by radiotherapy. VMAT plans were designed using both VitalBeam and Halcyon accelerators in flattening filter-free mode. The dosimetric parameters, plan complexity, verification pass rate, and execution efficiency were compared between the plans designed for both accelerators, with a significance level of P<0.05. Results In terms of target volume parameters, Halcyon 2.0 plans demonstrated superior homogeneity index and conformity index. For organs at risk, the Halcyon 2.0 plans showed lower doses for the lungs (D20% and Dmean) and heart (Dmean) compared to the VitalBeam plans (all P<0.05). Regarding plan complexity, Halcyon 2.0 plans exhibited better median average aperture area variation (0.35 ± 0.02), smaller aperture score, and larger median plan aperture area than VitalBeam plans (all P<0.05). However, VitalBeam plans had a superior median modulation complexity score (0.28 ± 0.01) compared to Halcyon 2.0 plans (P<0.05). Patient plans were assessed using the ArcCHECK phantom, revealing higher pass rates and significantly shorter execution time for Halcyon plans compared to VitalBeam plans (P<0.05). Conclusion Both Halcyon 2.0 and VitalBeam accelerators can provide high-quality VMAT plans for postoperative radiotherapy of breast cancer, with excellent verification pass rates ensuring treatment accuracy and efficacy. However, Halcyon 2.0 offers lower plan complexity, simplifies the treatment planning process, and reduces execution time, thereby achieving higher treatment efficiency and demonstrating greater advantages in clinical applications.

Objective:To compare the effects of erector spinae plane block at T 2 (T 2-ESPB) and nerve root block at C 5 (C 5-NRB) in patients undergoing arthroscopic shoulder surgery with general anesthesia. Methods:This was a randomized, controlled, non-inferiority study. Sixty American Society of Anesthesiologists Physical Status classification I or Ⅱ patients, aged 45-75 yr, with body mass index ≤35 kg/m 2, scheduled for elective arthroscopic shoulder surgery at Jining No. 1 People′s Hospital from April 2023 to February 2024, were included and divided into 2 groups ( n=30 each) using a random number table method: C 5-NRB group (group C) and T 2-ESPB group (group T). In group C, C 5-NRB was carried out by injecting 0.5% ropivacaine 5 ml. In group T, T 2-ESPB was performed by injecting 0.25% ropivacaine 30 ml. The efficacy of nerve block was assessed using a prick test at 30 min after administration, and then total intravenous anesthesia was performed in both groups. The time to first rescue analgesia (the non-inferiority boundary Δ =2 h), requirement for rescue analgesia within 24 h after operation and intraoperative consumption of anesthetics were recorded. The motor function of the affected limb during shoulder abduction, elbow flexion and elbow extension was assessed and scored using the modified Bromage scale (MBS) at 30 min and 4 and 12 h after nerve block. The diaphragmatic excursion was measured and recorded using M-mode ultrasound before nerve block and at 30 min after nerve block to evaluate the occurrence of diaphragmatic paralysis. Complications such as local anesthetic toxicity, recurrent laryngeal nerve block and pneumothorax were also recorded. Results:The mean difference (95% confidence interval) for the time to first rescue analgesia between the two groups was 5.551 (1.875-9.148) h, with the upper limit exceeding the non-inferiority boundary. Compared with group T, the intraoperative consumption of remifentanil was significantly reduced, the time to first rescue analgesia was prolonged, the consumption of morphine for rescue analgesia was decreased, MBS scores during shoulder abduction, elbow flexion and elbow extension were decreased at 30 min after block, and MBS scores during shoulder abduction and elbow flexion were decreased at 4 and 12 h after block in group C ( P<0.05). There was no significant difference in the diaphragmatic excursion, incidence of diaphragm paralysis and incidence of complications before and after block in the two groups ( P>0.05). Conclusions:C 5-NRB provides superior efficacy compared to T 2-ESPB when used for arthroscopic shoulder surgery under general anesthesia.

As an exclusive Miao medicine of Honwing Pharma (Guizhou) Co. Ltd., Yifei Zhike capsules are both a prescription drug and an over-the-counter (OTC) drug. Its main ingredients include Ranunculus ternatus and Panax notoginseng. With the effects of nourishing Yin and moistening the lungs, as well as relieving cough and reducing phlegm, Yifei Zhike capsules are often used in the treatment of acute and chronic bronchitis, pulmonary tuberculosis, and other diseases. However, there is insufficient understanding of their efficacy, suitable syndromes, and safety in clinical practice, with a lack of relevant expert consensus on clinical application. To standardize their clinical application, 30 experts from the fields of respiratory medicine, pharmacy, and evidence-based medicine were invited to develop an Expert Consensus on the Clinical Application of Yifei Zhike Capsules (Consensus for short) through evidence-based medicine methods. The Consensus clarified the syndrome characteristics, disease stages, dosages, treatment courses, combined medication, and other norms in the treatment of acute/chronic bronchitis and pulmonary tuberculosis and could be applicable to clinical physicians and pharmacists in medical and health institutions at all levels. In disease diagnosis, it provided diagnostic criteria for traditional Chinese medicine and Western medicine and clarified that the suitable traditional Chinese medicine syndrome was the syndrome of Qi-Yin deficiency with intermingled phlegm-blood stasis. Clinical studies have confirmed that Yifei Zhike capsules combined with standard anti-tuberculosis therapy can effectively improve the symptoms of pulmonary tuberculosis patients, increase the sputum smear conversion rate, and promote the absorption of lesions. When treating acute cough caused by respiratory tract infections, Yifei Zhike capsules can increase the markedly effective rate and the seven-day disappearance rate of cough symptoms. Meanwhile, recommendations for specific usage, dosages, and treatment courses were given for different diseases, and it was pointed out that long-term medication required key monitoring of adverse reactions. In safety, the adverse reactions of Yifei Zhike capsules involved multiple aspects such as the digestive system and allergic reactions, and pregnant women and women during menstruation were prohibited from using it. In addition, modern research has shown that Yifei Zhike capsules have an adjuvant therapeutic effect on tuberculous pleurisy and may be effective for inflammatory and benign pulmonary nodules. However, further research should be conducted on the toxicological safety of long-term medication. The formulation of the Consensus provides a scientific basis for the rational clinical application of Yifei Zhike capsules, which helps to improve clinical efficacy and reduce medication risks.

This paper aims to discuss the application value and progress of artificial intelligence (AI) in the diagnosis and treatment of gastrointestinal tumors and teaching practice of gastrointestinal oncology. Through a comprehensive analysis of the current clinical research status and literature, this paper summarizes the application practice and exploratory thinking of AI and deep learning technologies in gastrointestinal oncology. In diagnosis, AI technologies have improved the early detection and diagnosis efficiency for gastrointestinal tumors by optimizing medical image analysis, especially in the recognition of liver metastases. Applications of AI in pathological diagnosis include automatic recognition of tumor cells and tissue structure, as well as improving diagnostic sensitivity and specificity through feature extraction and pattern recognition. In treatment, the application scenarios of AI include rapid diagnosis, accurate staging, personalized treatment plan formulation, drug development, and surgical assistance. In surgical assistance, AI technology improves the safety and effectiveness of surgery through preoperative evaluation, surgical navigation, and postoperative evaluation. In teaching, AI technology facilitates knowledge acquisition and clinical skill enhancement of medical students by providing a multidisciplinary learning platform, simulating clinical environment and case details, and establishing a remote learning platform. The application of AI technology in teaching also includes deep learning and assessment feedback, providing personalized teaching and real-time assessment for students. This paper discusses the application prospects for AI technology in the teaching practice of gastrointestinal oncology. Although AI technology shows great potential in the diagnosis and treatment of gastrointestinal tumors and teaching gastrointestinal oncology, it also has limitations and needs to be combined with traditional teaching methods to achieve the best teaching results.

The v-Raf murine sarcoma viral oncogene homolog B (BRAF) gene is one of the most critical proto-oncogenes and functions as a key regulator in the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway. The incidence of BRAF mutations in non-small cell lung cancer (NSCLC) patients ranges from 1.5% to 5.5%, with BRAF V600 mutations accounting for approximately 30%-50% of all BRAF mutations, among which BRAF V600E represents the most prevalent mutation type. Currently, the combination of Dabrafenib and Trametinib has been recommended as first-line therapy for BRAF V600-mutant NSCLC by multiple domestic and international guidelines including National Comprehensive Cancer Network (NCCN), European Society of Medical Oncology (ESMO), and Chinese Society of Clinical Oncology (CSCO). However, there are no clear targeted treatment recommendations for BRAF non-V600 mutations. Although case reports suggest that Dabrafenib combined with Trametinib may be effective for patients with BRAF non-V600 mutations, the efficacy and safety require further validation due to limited sample size and lack of large-scale clinical trial data. This article reports a case of NSCLC with a rare BRAF insertion and deletion mutation that responded well to the treatment of Dabrafenib in combination with Trametinib, aiming to enhance clinicians' understanding of such NSCLC cases with extremely rare mutation and provide a reference for future treatment strategies.
