Objective Taking typical cases of Western medicine as an example,this paper explores the connection between Chinese and Western medicine on the understanding of tongue elephants.Methods After collecting the literature with tongue diagram attached to the clinical imaging column published in NEJM magazine,extracting the symptoms,signs and Western medicine disease information recorded in the literature,the tongue diagram was diagnosed from three aspects:tongue quality,tongue moss and sublingual meridians,and whether the symptoms and signs of tongue correspond to a certain diagnosis result,and the results were analyzed.Results A total of 48 articles were included,including 6 literature on abnormal tongue dynamics,which could correspond to abnormal tongue morphology in traditional Chinese medicine.Thirty-four cases of abnormal tongue shape were found.Among them,12 cases could be diagnosed with corresponding TCM tongue diagnosis,including 7 cases of abnormal tongue shape and 5 cases of abnormal coating.The remaining 22 cases were secondary changes in tongue structure.There were 8 articles on abnormal tongue color,including 1 abnormal tongue color,1 abnormal sublingual chord,and 6 abnormal lichen color.Conclusion Starting from the form and function,explore the connection between Chinese medicine and Western medicine in their understanding of tongue diagnosis,and promote the objectification and standardization of Chinese medicine tongue diagnosis.

Esophageal cancer is one of the most common malignant tumors in China. The comprehensive treatment of esophageal cancer based on operation is important. In recent ten years, with the development of surgical techniques and medical instruments, tubular stomach has been widely used. Although the advantages of tubular stomach are becoming more and more obvious, there are still many details and problems for the function and application of tubular stomach worthy of further discussion and study. In this paper, the technical progress, advantages, functions and applications of tubular stomach are reviewed and discussed, and the future prospect is predicted.

Objective To explore the feasibility and safety of non-gastrointestinal decompression after esophagectomy and the necessity of gastric tube or the time to remove gastric tube. Methods Thirty patients with esophageal cancer who underwent surgical treatment in the Department of Thoracic and Cardiovascular Surgery, Nanjing Drum Tower Hospital, were included in the trial from June to October 2017. The patients were randomly and equally assigned to a trial group (non-gastrointestinal decompression) or a control group (gastrointestinal decompression). There was no significant difference in age (P=1.000), sex (P=1.000), tumor location (P=0.732), pathological type (P=1.000), pathological stage (P=0.507), and operation time (P=0.674) between the two groups. The clinical effect between the two groups were compared. Results There was no statistical difference in incidences of anastomotic leakage (P=1.000), anastomotic bleeding (P=1.000), gastroesophageal reflux (P=1.000) between the two groups. And there was no statistical difference in time of the first flatus (P=0.629) and the first bowel movement (P=0.599) after operation between the two groups. Conclusion Without gastrointestinal decompression after Ivor Lewis esophagectomy does not increase the incidences of anastomotic leakage, anastomotic bleeding and gastroesophageal reflux, and has no significant effect on the recovery of gastrointestinal function. Without gastrointestinal decompression after Ivor Lewis esophagectomy is safe and feasible. Removing gastric tube on the second day after operation is reasonable and feasible.

Objective    To explore the application value of CT-guided microcoil localization in pulmonary nodule (diameter≤15 mm) surgery. Methods    The clinical data of 175 patients with pulmonary nodules who underwent single utility port video-assisted thoracoscopic surgery at Nanjing Drum Tower Hospital from August 2018 to December 2019 were retrospectively analyzed. According to whether CT-guided coil localization was performed before operation, they were divided into a locating group and a non-locating group. There were 84 patients (34 males, 50 females, aged 57.8±8.8 years) in the locating group and 91 patients (46 males, 45 females, aged 57.6±10.8 years) in the non-locating group. The localization success rate, localization time, incidence of complications, surgical and postoperative conditions were analyzed between the two groups. Results    All 84 patients in the locating group were successfully located, and localization time was 19.0±3.6 minutes. Among them, 19 (22.6%) patients had a small pneumothorax, 4 (4.8%) pulmonary hemorrhage and 2 (2.4%) coil shift; 6 (7.1%) patients had mild pain, 3 (3.6%) moderate pain and 1 (1.2%) severe pain. Sex (P=0.181), age (P=0.673), nodule location (P=0.167), nature of lesion (P=0.244), rate of conversion to thoracotomy (P=0.414), rate of disposable resection of nodules (P=0.251) and postoperative hospital stay (P=0.207) were similar between the two groups. There were significant differences in nodule size (P<0.001), nature of nodule (P<0.001), the shortest distance from nodule to pleura (P<0.001), operation time (P<0.001), lung volume by wedge resection (P=0.031), number of staplers (P<0.001) and total hospitalization costs (P<0.001) between the two groups. Conclusion    CT-guided microcoil localization has the characteristics of high success rate, and is simple, practicable, effective, safe and minimally invasive. Preoperative CT-guided microcoil localization has important clinical application value for small pulmonary nodules, especially those with small size, deep location and less solid components. It can effectively shorten the operation time, reduce surgical trauma and lower hospitalization costs, which is a preoperative localization technique worthy of popularization.

Objective To develop an innovative recognition algorithm that aids physicians in the identification of pulmonary nodules. Methods Patients with pulmonary nodules who underwent thoracoscopic surgery at the Department of Thoracic Surgery, Affiliated Drum Tower Hospital of Nanjing University Medical School in December 2023, were enrolled in the study. Chest surface exploration data were collected at a rate of 60 frames per second and a resolution of 1 920×1 080. Frame images were saved at regular intervals for subsequent block processing. An algorithm database for lung nodule recognition was developed using the collected data. Results A total of 16 patients were enrolled, including 9 males and 7 females, with an average age of (54.9±14.9) years. In the optimized multi-topology convolutional network model, the test results demonstrated an accuracy rate of 94.39% for recognition tasks. Furthermore, the integration of micro-variation amplification technology into the convolutional network model enhanced the accuracy of lung nodule identification to 96.90%. A comprehensive evaluation of the performance of these two models yielded an overall recognition accuracy of 95.59%. Based on these findings, we conclude that the proposed network model is well-suited for the task of lung nodule recognition, with the convolutional network incorporating micro-variation amplification technology exhibiting superior accuracy. Conclusion Compared to traditional methods, our proposed technique significantly enhances the accuracy of lung nodule identification and localization, aiding surgeons in locating lung nodules during thoracoscopic surgery.
