Developing an intelligent agent for integrated traditional Chinese and western medicine diagnosis and treatment based on clinical practice guidelines is a key approach to advancing the standardization and intelligent deve-lopment of traditional Chinese medicine （TCM） and to supporting clinical decision-making. This paper argues for the necessity of building a knowledge base using guidelines as the sole data source， systematically identifies five core methodological challenges across the entire process， and proposes corresponding solutions. An ontology framework capable of distinguishing between TCM and western medicine concepts should be designed to address the difficulty of knowledge integration. A closed-loop "algorithm-based extraction-expert review" model is adopted to reduce data extraction errors. Expert consensus is incorporated to address decision gaps in specific clinical scenarios outlined in the guidelines， while a multi-stage， standardized output process for the AI system is established to eliminate model hallucinations. Furthermore， an evaluation framework reflecting clinical applicability is developed to enhance the AI system's accuracy and stability. Throughout the research process， it is essential to ensure the in-depth and continuous participation of multidisciplinary experts， strictly control the selection and quality evaluation of guidelines， and rely on the expert consensus method to address decision gaps in the knowledge base. Additionally， continuous validation and iterative optimization of intelligent agents are required to ensure the accuracy and stability of generated outputs. Limitations remain in the mechanisms for real-time knowledge synchronization in intelligent diagnostic and treatment systems， and further validation through large-scale real-world studies is warranted.

Sepsis exhibits substantial biological heterogeneity. Transcriptome-based subtyping systems， such as sepsis response signature （SRS） subtypes， molecular diagnosis and risk stratification of sepsis （MARS）， inflammation/adaptive/coagulation subtyping， and consensus transcriptomic subtypes， have provided a crucial basis for elucidating the molecular mechanisms of sepsis and guiding precision treatment. Using a literature review approach， this study systematically summarizes the immune subtyping systems of sepsis and their molecular basis， and explores the potential correspondence between traditional Chinese medicine （TCM） syndromes and immune subtypes. It is found that the heat-toxin syndrome tends to correspond to the hyperinflammatory subtype， the stasis-toxin syndrome to the coagulopathy subtype， and the deficiency syndrome to the immunosuppressive subtype. These findings may provide new insights for precision therapy of sepsis through integrated Chinese and western medicine.

Objective:To investigate the effects of anisodamine hydrobromide (654-1), 654-1+ norepinephrine and norepinephrine on early hemodynamic indexes of piglets with septic shock.Methods:A total of 38 healthy Bama pigs were selected as the study subjects, 32 of which were treated with lipopolysaccharide to create septic shock piglet model, and the other 6 were sham operation group. The animals were randomly divided into control group ( n=8), drug treatment group [654-1 group ( n=8), 654-1+ norepinephrine group ( n=8), norepinephrine group ( n=8)]. Hemodynamic parameters were recorded at T 0 (basic state), T 1 (successful shock modeling), T 2 (1 h after successful modeling), T 3 (2 h after successful modeling), T 4 (4 h after successful modeling), T 5 (6 h after successful modeling) and T 6 (8 h after successful modeling) respectively, including: Mean arterial pressure (MAP), cardiac index (CI), whole-heart end-diastolic volume index (GEDI), lactic acid (LAC).

Objective To investigate the diagnosis value of narrow band imaging(NBI)endoscopy in evalua-ting the degenerative properties of vocal cord leukoplakia.Methods A retrospective analysis of clinical data from 95 cases(153 sides)of vocal cord leukoplakia patients was conducted.All patients underwent electronic laryngoscopy before microlaryngoscopy.The lesions of vocal cords were examined with white light and then with NBI mode.The superficial IPCL patterns were classified into six types(types Ⅰ-Ⅵ).Under the NBI endoscope,the vocal cord leu-koplakia was classified as 1)Group A:types Ⅰ,Ⅱ,and Ⅲ.The pathological results were regarded as the gold standard for definitive diagnosis of vocal cord leukoplakia.and 2)Group B:types Ⅳ,Ⅴ,and Ⅵ.All patients un-derwent laryngeal microsurgery under general anesthesia,and lesions were sent for pathological examination.The results of NBI assessment were compared with those of pathology.The sensitivity,specificity,accuracy and Kappa-Cohen index of NBI in assessing the nature of lesions were calculated.Results According to NBI endoscopy,123 lesions(80.4％)were classified as low-risk group(type Ⅰ:18,type Ⅱ:41,type Ⅲ:64)and possibly benign le-sions,while 30 lesions(19.6％)were classified as high-risk group(type Ⅳ:2,type Ⅴ:25,type Ⅵ:3)and possi-bly malignant lesions.The pathological results showed that the 121 lesions(79.1％)were hyperkeratosis(20 le-sions),mild(39 lesions),moderate atypical hyperplasia(62 lesions),and the 32 lesions(20.9％)were severe a-typical hyperplasia(5 lesions),carcinoma in situ(22 lesions),and invasive carcinoma(5 lesions).In the low-risk group,2 lateral lesions were pathologically severe atypical hyperplasia.The sensitivity,specificity,positive predic-tive value,negative predictive value,and accuracy of NBI in predicting the malignancy of leukoplacia were 100％,97.6％,90％,100％,and 98％,respectively.Kappa-Cohen index was 0.90(95％confidence interval 82.3％to 100％).Conclusion NBI endoscopy can accurately evaluate the pathological properties of vocal cord leukoplakia.

Objective    To compare the perioperative outcomes between robot-assisted complex segmentectomy and simple segmentectomy for stage ⅠA non-small cell lung cancer (NSCLC). Methods    The clinical data of 285 patients with NSCLC undergoing robot-assisted thoracic surgery (RATS) in our hospital from January 2015 to August 2021 were retrospectively analyzed. There were 105 males and 180 females aged 23-83 years. The patients were divided into a complex segmentectomy group (n=170) and a simple segmentectomy group (n=115) according to tumor location and surgical method. The clinical pathological baseline characteristics and perioperative outcomes between the two groups were compared, including operative time, blood loss volume, dissected lymph nodes, conversion rate, postoperative duration of drainage, postoperative hospital stay, the incidence of persistent air leakage and postoperative 30 d mortality. Results    There was no statistical difference in baseline data between the two groups (P>0.05). No postoperative 30 d death was observed. One patient in the complex segmentectomy group was transferred to thoracotomy. No statistical difference was observed between the two groups in the operative time (97.36±38.16 min vs. 94.65±31.67 min, P=0.515),  postoperative duration of drainage (3.69±1.85 d vs. 3.60±1.90 d, P=0.679), postoperative hospital stay (4.07±1.85 d vs. 4.05±1.97 d, P=0.957), dissected lymph nodes (5.15±3.53 vs. 5.13±2.93, P=0.952), incidence of blood loss volume<100 mL (98.2% vs. 99.1%, P=0.650), and incidence of postoperative persistent air leakage (6.5% vs. 5.2%, P=0.661). Conclusion    The safety and effectiveness of robot-assisted complex segmentectomy and simple segmentectomy are satisfactory in the treatment of stage ⅠA NSCLC. The perioperative results of RATS complex segmentectomy and simple segmentectomy are similar.

Objective    To investigate the effectiveness and safety of robotic lobectomy in clinical N0 lung malignant tumor≥3 cm. Methods    We retrospectively analyzed the clinical data of 182 patients with lung malignant tumor≥3 cm receiving robotic or thoracoscopic lobectomy at Shanghai Chest Hospital in 2019. The patients were divided into a robotic surgery group (RATS group) and a thoracoscopic surgery group (VATS group). There were 39 males and 38 females with an average age of 60.55±8.59 years in the RATS group, and 51 males and 54 females with an average age of 61.58±9.30 years in the VATS group. A propensity score matching analysis was applied to compare the operative data between the two groups. Results    A total of 57 patients were included in each group after the propensity score matching analysis. Patients in the RATS group had more groups of N1 lymph node dissected (2.53±0.83 groups vs. 2.07±0.88 groups, P=0.005) in comparison with the VATS group. No statistical difference was found in operation time, blood loss, postoperative hospital stay, number of N1 and N2 lymph nodes dissected, groups of N2 lymph node dissected, lymph node upstage rate or postoperative complications. The hospitalization cost of RATS was higher than that of VATS (P<0.001). Conclusion    In contrast with thoracoscopic lobectomy, robotic lobectomy has similar operative safety, and a thorough N1 lymphadenectomy in patients with clinical N0 lung malignant tumor≥3 cm.

Objective:To discuss the the effects, indications and protective measures of tracheotomy for severe cases of coronavirus disease 2019 (COVID-19) patients.Methods:A retrospectively analysis was conducted to explore the clinical data of COVID-19 patients who received tracheotomy in February to March 2020, and descriptive statistics were used to analyze the indication of tracheotomy, particularity of intraoperative treatment and protective measures.Results:A total of 4 cases were included in this article. All patients were successfully operated. One case had postoperative incision continuous bleeding, there were not other complications and nosocomial infection among the medical staff. The patient′s condition was relieved in different degrees after the operation, who remained hospitalized.Conclusion:Tracheotomy for severe cases of COVID-19 can achieve certain curative effect, but the occurrence of tracheotomy related complications and nosocomial infection should be effectively controlled, and the risk benefit ratio of tracheotomy should be carefully weighed before surgery.

Objective To explore the clinical significance of the ratio of descending aorta diameter to ascending aorta diameter (rDA) in rapid diagnosis of Stanford B aortic dissection (AD). Methods A total of 118 patients with chest pain admitted to the emergency department from January 2013 to June 2018 in the People′s Hospital of Longhua were selected,and 42 patients with Stanford B type AD (group A) and 76 patients without AD (group B) were diagnosed by CT angiography.Eighty healthy people in the same period were selected as control group (group C). The descending aorta diameter and ascending aorta diameter were measured and rDA was calculated. The receiver operating characteristic curves were made. The sensitivity and specificity of descending aorta diameter and rDA for predicting Stanford B-type AD were analyzed. Results The descending aorta diameter, ascending aorta diameter and rDA in group A (male and female) were significantly higher than those in group C (male and female), while the descending aorta diameter and rDA in group A (male and female) were significantly higher than those in group B (male and female) (P<0.05). The sensitivity and specificity of descending aorta diameter with 30.0 mm as the cut-off point for the diagnosis of Stanford B-type AD were 92.9%(39/42),82.9%(63/76), and those of rDA with 0.8 as the cut-off point for Stanford B-type AD were 95.2%(40/42),90.8%(69/76). Conclusions The descending aorta diameter and rDA can be used as indicators for rapid diagnosis of Stanford B-type AD, and rDA is better than the diameter of descending aorta.
