The philosophy of “treating disease before its onset” is a fundamental concept of traditional Chinese medicine (TCM), permeating its diagnostic and therapeutic framework, and is central to clinical practice. However, current TCM diagnostic and treatment models for the “pre-disease to disease” window period face several limitations, including the lack of comprehensive clinical parameters, difficulties in characterizing and integrating heterogeneous multimodal data, and insufficient dynamic precision in interventions and efficacy evaluations. To address these issues, guided by Professor Candong Li’s theory of TCM stateology, this study focuses on integrating objective multimodal data. It proposes a new model for personalized TCM diagnosis and treatment targeting the “pre-disease to disease” window period. This approach first proposes the idea of restructuring the conceptual framework of “symptom” and integrating multi-source heterogeneous data at macroscopic, mesoscopic, and microscopic levels to form a three-dimensional assessment indicator system. By integrating graph neural networks, convolutional neural networks, attention mechanisms, and knowledge graph-guided weight allocation, this approach enables collaborative representation, alignment, and fusion of multi-source data. Subsequently, it plans to construct a multimodal fusion model at both feature and decision levels, in order to establish mappings between indicators and TCM state elements, and to screen key indicators characterizing pathological evolution during the window period. Furthermore, it proposes a technical path for enhancing model interpretability using methods such as SHapley Additive exPlanations (SHAP) and Ablation-CAM++. Finally, with state assessment as the core, it proposes the concept of constructing a dynamic evaluation method for individualized diagnosis and treatment based on time-series data analysis using algorithms such as long short-term memory (LSTM) networks and gated recurrent units (GRUs). Moreover, a causal inference framework and semi-supervised learning strategies are introduced to enable quantitative evaluation of individual intervention effects and to provide interpretable therapeutic feedback, forming a complete technical path from data representation and fusion, weight adjustment, and interpretability analysis, to dynamic diagnosis feedback. This study aims to address deficiencies in the current TCM diagnosis and treatment model during the “pre-disease to disease” window period and to provide an operational framework for the clinical practice of TCM’s “treating disease before its onset”.

Objective To observe the correlations of artificial intelligence(AI)measured parameters on anteroposterior and lateral spinal X-ray films with the severity of adolescent idiopathic scoliosis(AIS).Methods Totally 1 786 AIS patients were retrospectively enrolled.Parameters including Cobb angle(CA),coronal balance distance(CBD),T1 slope(T1S),pelvic tilt(PT),sacral slope(SS),apical vertebral translation(AVT),thoracic trunk shift(TTS),thoracic kyphosis(TK)and sagittal vertical axis(SVA)on anteroposterior and lateral spinal X-ray films were measured using uAI DR scoliosis analysis system.The severity of AIS was evaluated according to CA,and the correlations between other parameters and the severity of AIS were explored.The above parameters were compared under different severity levels and coronal/sagittal equilibrium states.Multivariate logistic regression analysis was performed to screen the independent impact factors on the severity of AIS.Results Significant differences of the above parameters were found among different severity levels except for SVA(all P＜0.001).With the aggravation of AIS,CA,CBD,AVT and TTS increased successively(all P＜0.001).T1S of severe AIS was higher than that of mild and moderate AIS(both P＜0.001),PT and SS of moderate and severe AIS were all bigger,while their TK were smaller than those of mild AIS(all P＜0.001).Significant differences of CA,T1S,PT,SS,AVT,TTS and TK were found between coronal balanced and imbalanced AIS(all P＜0.05),while of TK were found between sagittal balanced and unbalanced AIS(P=0.026).CBD,T1S,PT,SS,AVT and TTS were all positively correlated(r,=0.136-0.606,all P＜0.001),while TK was negatively correlated(r,=—0.404,P＜0.001)with the severity of AIS.T1S,AVT and TTS were all independent impact factors of the severity of AIS(all P＜0.001).Conclusion Among AI measured parameters on anteroposterior and lateral spinal X-ray films,CBD,T1S,PT,SS,AVT and TTS were positively correlated,while TK was negatively correlated with the severity of AIS.

Objective:To assess the effect of using different thicknesses of reconstruction layer and different thicknesses of region of interest (ROI) on the results of vertebral bone mineral density (BMD) values that were measured by quantitative computed tomography (QCT). Methods:A total of 100 patients who underwent QCT screening for opportunistic osteoporosis between May and September 2021 at the First Affiliated Hospital of Zhengzhou University were retrospectively collected. Images that the thicknesses of QCT reconstruction layer were respectively 1 and 5 mm were transferred to the QCT Pro workstation,and ROI thicknesses were adjusted to 5,7,and 9 mm,respectively. The average BMD values of QCT measurements were recorded under different thicknesses of reconstruction layer and different ROI thicknesses. Then,the effects of the choose of different thicknesses of reconstruction layer and the different ROI thicknesses on BMD values that were measured by QCT were analyzed. Results:The average BMD values of 1 mm and 5 mm thicknesses of reconstruction layer were respectively (117.41±45.97) mg/cm3 and (118.77±44.84) mg/cm3 when ROI thickness was 5 mm,with a statistically significant difference (t=-2.283,P<0.05). The average BMD values of 1 mm and 5 mm thicknesses of reconstruction layer were respectively (116.38±46.06) mg/cm3 and (119.06±44.55) mg/cm3 when the ROI thickness was 7mm,and the difference was statistically significant (t=-3.280,P<0.05). The average BMD values of 1 mm and 5 mm thicknesses of reconstruction layer were respectively (116.25±45.36) mg/cm3 and (120.12±44.10) mg/cm3 when the ROI thickness was 9 mm,and the difference was statistically significant (t=-5.841,P<0.001). The differences in BMD measurement values among 5,7 and 9 mm ROI thicknesses were not statistically significant when the thicknesses of reconstruction layer were respectively 1 and 5 mm. Conclusion:There is an effect of the thickness of QCT reconstruction layer on average BMD measurement values,and 1 mm thickness of reconstruction layer is more suitable to clinical application,while there is not significant effect in ROI thickness on average BMD measurement value of QCT. In clinical application,it is feasible to adjust ROI thickness according to actual situation so as to avoid the effect caused by some factors such as fracture or vertebral implants.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To explore the feasibility and and clinical efficacy of lingual mucosa replacement ureteral stenosis repair and plasty for the treatment of long segment ureteral polyps.Methods:Clinical data of 3 patients (4 sides) with long-segment ureteral polyps admitted to the Second Hospital of Lanzhou University from October 2017 to October 2019 were retrospectively analyzed. Two cases were male and one case was female. The ages were22, 16, and 45 years old. Preoperative urologic ultrasound, CT urography and ureteroscopy were performed. The lesions were located on the left side in 3 cases and on the right side in 1 case; the stenosis was located in the middle and upper ureter; the length of the ureteral stenosis was 6, 7, 6, and 6 cm, respectively; and the preoperative blood creatinine was 72, 85, and 70 μmol/L, respectively. Three cases underwent ureteral stenosis repair and plasty with tongue mucosal substitution. During the operation, the ureter was fully exposed and longitudinally incised, polyps were removed, and 7.0-10.0 cm long and 1.5-2.0 cm wide lingual mucosa was harvested according to the length of the stenosis, and then the lingual mucosa was transplanted to the muscular layer and the inner surface of the sheath in the stenosed ureter, fixed with 6-0 thread until the muscular layer was rolled into shape and wrapped with a large omentum. All of them left one double-J tube in the ureter on the affected side. Perioperative results and complications were recorded. The patients' blood creatinine and anterior and posterior renal pelvic diameters were compared before and after treatment.Results:In our study, all three 4-sided surgeries were successfully completed without any serious intraoperative or postoperative complications (Clavien-Dindo score ≥ grade Ⅲ). Mean surgical. Time was (240.0±49.0) min, intraoperative bleeding was 50 ml, postoperative drain retention time was (6.3±2.5) d, and median postoperative hospitalization time was 6.5(3, 9)d. The double J-tube was removed at 3 months postoperatively, and renal function and imaging tests were reviewed. Because the postoperative follow-up results of patient 1 were missing, the mean value of blood creatinine in the other 2 patients was 73.0 μmol/L at 3 months postoperatively, which was significantly improved compared with the preoperative value of 58.2 μmol/L, and the difference was statistically significant ( P < 0.05). And the average value of anterior and posterior renal pelvic separation diameters of the other 2 patients after surgery was <5 mm, which was significantly improved compared with the preoperative value of 17.9 mm, but the difference was not statistically significant ( P>0.05).There was no restenosis in all 2 patients after surgery, and the intravenous urography showed that the ureter was patent after the surgery, and the degree of urinary obstruction did not aggravate. The group was followed up for 3 to 8 months (mean 4.7 months), and no recent complications have occurred so far. Conclusions:Lingual mucosa replacement ureteral stenosis repair and plasty for the treatment of ureteral polyps in the long segment has a high success rate and precise efficacy, and its operation is feasible.
