Traditional Chinese medicine formula (TCMF) represents a fundamental component of Chinese medical practice, incorporating medical knowledge and practices from both Han Chinese and various ethnic minorities, while providing comprehensive insights into health and disease. The foundation of TCMF lies in its holistic approach, manifested through herbal compatibility theory, which has emerged from extensive clinical experience and evolved into a highly refined knowledge system. Within this framework, Chinese herbal medicines exhibit intricated characteristics, including multi-component interactions, diverse target sites, and varied biological pathways. These complexities pose significant challenges for understanding their molecular mechanisms. Contemporary advances in artificial intelligence (AI) are reshaping research in traditional Chinese medicine (TCM), offering immense potential to transform our understanding of the molecular mechanisms underlying TCMFs. This review explores the application of AI in uncovering these mechanisms, highlighting its role in compound absorption, distribution, metabolism, and excretion (ADME) prediction, molecular target identification, compound and target synergy recognition, pharmacological mechanisms exploration, and herbal formula optimization. Furthermore, the review discusses the challenges and opportunities in AI-assisted research on TCMF molecular mechanisms, promoting the modernization and globalization of TCM.

Objective:To evaluate the short-term efficacy of endoscopic-laparoscopic regional gastric resection combined with sentinel lymph node basin dissection in patients with early-stage gastric cancer.Methods:This is a retrospective case series study. Data of 17 consecutive early gastric cancer patients from a prospective cohort at Beijing Friendship Hospital,Capital Medical University were analyzed between August 2023 and August 2024. Sixteen cases were from the department of general surgery and 1 from the department of gastroenterology. The cohort included 9 males and 8 females,with a mean age of 61.4 years (range: 46 to 79 years). Clinical data,including demographics,pathological features,surgical procedures,and follow-up outcomes,were collected through medical records and databases. All patients were followed for over 3 months,with follow-up ending on December 5,2024.Results:A total of 17 patients were involved. Among them, 5 patients underwent endoscopic submucosal dissection (ESD) combined with laparoscopic sentinel lymph node dissection (LSBD),and another 3 patients who underwent complete ESD resection received LSBD due to pathological stage meeting the expanded indications. 6 patients who underwent non-curative ESD resection received laparoscopic gastric regional resection (LRG) combined with LSBD,and another 3 patients directly received LRG combined with LSBD. The average number of sentinel lymph nodes dissected before surgery ( M(IQR)) was 8.9 (4.5) (range: 4 to 21),and the detection rate and accuracy rate were both 100%. Postoperative pathology confirmed that there was no metastasis in the sentinel lymph nodes of 5 patients who underwent ESD combined with LSBD and 3 patients who underwent LSBD after complete ESD resection. The vertical and horizontal margins of ESD were all negative. One patient was an absolute indication for ESD. For the 6 patients who underwent non-curative ESD resection combined with LRG and LSBD,the horizontal margins were all negative. Two patients showed 1 metastasis in each of the 21 and 9 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed during the operation. Postoperatively,73 and 39 lymph nodes were retrieved respectively. The former had 1 additional metastasis,while the latter had no metastasis. Among the 3 patients who underwent direct LRG combined with LSBD,the horizontal margins were negative. One patient was confirmed as an absolute indication for ESD by postoperative pathology,and one patient had 1 metastasis in 8 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed. Postoperatively,there was no metastasis in 54 lymph nodes. All patients had no complications such as infection,bleeding,perforation,or death after surgery. Among the 14 patients who did not receive additional radical surgery,they were able to pass gas and defecate within 3 days after surgery,with an average hospital stay of 6 days. The nutritional indicators and gastric radionuclide emptying imaging half-emptying time were similar to those before surgery at 3 months after surgery. Conclusions:Laparoscopic and endoscopic cooperative regional gastrectomy with sentinel lymph node basin dissection has the advantages of minimal invasiveness,preservation of gastric function,and precise treatment. It maybe suitable for patients with early-stage gastric cancer at high risk of lymph node metastasis and has good short-term efficacy.

Objective To investigate the characteristics of changes in blood uric acid(UA)and detection rate of hyperuricemia(HUA)among officers and soldiers during long-term maritime missions,as well as their related influencing factors.Methods A total of 100 servicemen were randomly selected from 240 officers and soldiers who will participate in a long-distance voyage mission.Their general information,including age,education level,administrative position,years of service on board,and department,was surveyed.Their annual data of physical examination were retrospectively analyzed and compared with the results of another 335 shore-based servicemen during the same period.On mission day 10(D10)and day 50(D50),the venous blood samples were collected from the participants to synchronously measure blood UA level and body composition indicators(body fat mass,BMI,fat percentage,fat mass,muscle mass,and muscle percentage).Additionally,on D50,Self-Rating Scale of Sleep(SRSS)and Symptom Checklist-90(SCL-90)were employed to survey their conditions.Seventy service members were randomly selected from the 100 participants to engage in aerobic exercise.The changes in UA level and detection rate of HUA among the mission personnel were analyzed,along with their influencing factors.Results The UA level and HUA detection rate in long-term navigation personnel during concurrent annual physical examinations were significantly lower than those in shore-based personnel(P<0.01).Compared to pre-voyage physical examination results,the UA level and HUA detection rate in long-term navigation personnel were significantly increased from mission day D10(P<0.001).Compared to the values at D10,the UA level and HUA detection rate at D50 showed significant decreases(P<0.05),and then essentially returned to pre-mission examination levels(P>0.05).Aged<32 years was an independent risk factor for new-onset HUA at mission D10(P<0.05).<32 years old and aerobic exercise during the voyage were independent influencing factors for HUA outcome(P<0.05).Conclusion Serum UA level and HUA detection rate among officers and soldiers participating in long-term maritime missions are relatively low before departure,but in significant increases during the early stages of the mission,particularly among those aged<32 years.Scientific aerobic exercise during the mission period helps reduce UA level and HUA detection rate,playing a crucial role in guaranteeing physical and mental health.

Objective:To assess the predictive value of the percentage of Gleason pattern 4 (G4%) in prostate biopsy for adverse pathology and biochemical recurrence.Methods:We retrospectively analyzed consecutive patients who underwent radical prostatectomy in our institution between January 2019 and December 2023, and included those who were diagnosed with ISUP 2-3 cancer at biopsy. A total of 109 patients were included in this study. The average age of patients was (67.40±6.11) years, and the average BMI of patients was (25.36±2.97) kg/m 2. 49 Cases (45.0%) had a PI-RADS score of 5, and the median prostate volume was 32.60 (24.57, 45.63) ml. The median of most recent tPSA before biopsy was 9.76 (6.89, 12.95) ng/ml, the median PSAD was 0.28 (0.17, 0.44) ng/ml 2, and the median f/tPSA was 0.11 (0.08, 0.16). Clinical T 2b or higher stage was found in 84 cases (77.1%). The total biopsy core length was (22.91±5.18) cm, with a median of 24 (20, 24) biopsy cores and a median of 6 (4, 9) positive cores. Gleason score 3+ 4 was found in 52 cases (47.7%), and Gleason score 4+ 3 in 57 cases (52.3%). Cribriform was present in 30 cases (27.5%). G4% was calculated based on the proportion of Gleason grade 4 tumor relative to total tumor, tumor proportion relative to total tissue, and tissue length. Patients were divided into high-G4% (≥2.45%) and low-G4% (<2.45%) groups based on the median G4% value, with 55 and 54 cases, respectively. No significant differences were observed in baseline characteristics between the two groups ( P>0.05). The main risk factor of adverse pathology was analyzed by logistic regression, and receiver operating characteristic (ROC) curve and area under curve (AUC) were performed. Patients were further stratified by the G4% cutoff value from ROC, and Kaplan-Meier survival curves were plotted to compare biochemical recurrence free survival (BCRFS) between groups. The main risk factor affecting BCRFS was analyzed by Cox regression. Adverse pathology was defined as postoperative Gleason score ≥4+ 3 or pathological stage ≥T 3a. Results:Adverse pathology occurred in 44 (80.0%) high-G4% and 16 (29.6%) low-G4% patients ( P<0.01). Multivariate analysis identified G4% as an independent risk factor for adverse pathology ( OR=1.23, 95% CI 1.02-1.50, P=0.033). The highest ROC AUC value was seen for G4% (0.799), significantly outperforming Gleason score (0.799 vs. 0.641, P=0.003), tPSA (0.799 vs. 0.615, P=0.003), PSAD (0.799 vs. 0.679, P=0.038), positive cores (0.799 vs. 0.677, P=0.009), clinical T stage (0.799 vs. 0.607, P=0.001) and cribriform (0.799 vs. 0.639, P=0.001). The G4% cutoff value for predicting biochemical recurrence was 10.97%. The median BCRFS was significantly higher in the low G4% (<10.97%) group than that in the high G4% (≥10.97%) group (55 vs. 28 months, P=0.002). Cumulative recurrence free survival rates at 1 and 3 years were 94.6% vs. 74.1% and 78.0% vs. 47.6%, respectively. Multivariate Cox regression analysis indicates that G4% was an independent risk factor affecting BCRFS ( HR=1.11, 95% CI 1.00-1.23, P=0.041). Conclusions:For patients with ISUP 2-3 nmPCa, a higher G4% in biopsy specimens demonstrates strong predictive ability for adverse pathology and biochemical recurrence, outperforming traditional clinical indicators such as Gleason score and PSA.
