Endometriosis (EMS) is a chronic systemic disease prevalent in women of reproductive age. The signs and symptoms of this disease are not specific, and the severity of the disease varies, leading to clinical heterogeneity, which increases the difficulty of diagnosis. It seriously affects the quality of life of patients and also occupies a large amount of social health resources. Artificial intelligence (AI) refers to the ability of a computer technology to enable machines to simulate human intelligence, including perception, learning, reasoning, decision making and language understanding. AI serves as a powerful data-mining tool capable of processing large amounts of medical data and diagnosing, managing, and treating patients according to their specific conditions. Especially in the diagnostic process of EMS, the use of AI can improve the detection rate and shorten the diagnostic time while increasing the diagnostic sensitivity and specificity. In this paper, we provide an overview of the application of medical big data and AI to the diagnosis and treatment of EMS in order to provide new aids to further improve diagnostic efficiency and therapeutic efficacy.

ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndromes in intrahepatic cholestasis of pregnancy (ICP) and its association with perinatal outcomes, and to provide a basis for precise treatment based on TCM syndrome differentiation. MethodsA cross-sectional study was conducted among 275 patients with ICP who were admitted to The Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from April 2023 to April 2025. A hierarchical cluster analysis was used to summarize TCM syndromes. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A multivariate Logistic regression analysis was used to identify the clinical features significantly associated with TCM syndrome. ResultsThe cluster analysis identified three core TCM syndromes among the 275 patients with ICP, i.e., liver-gallbladder damp-heat syndrome (45.8%), syndrome of blood deficiency generating wind (30.9%), and liver depression and spleen deficiency syndrome (23.3%). There was a significant difference in the distribution of TCM syndromes between different groups stratified by maternal age at delivery, parity, history of ICP recurrence, gestational weeks at disease onset, total bile acid (TBA), alanine aminotransferase (ALT), and comorbidity with gestational diabetes mellitus (GDM) (all P<0.05). The multivariate Logistic regression analysis showed that<34 gestational weeks at disease onset was significantly associated with all three syndromes (damp-heat: odds ratio [OR]=3.769, P<0.001; blood deficiency: OR=4.031, P<0.001; liver stagnation: OR=3.552, P<0.001). Liver-gallbladder damp-heat syndrome was associated with maternal age ≥35 years at disease onset (OR=2.048, P=0.014), parity ≥2 times (OR=1.921, P=0.034), history of ICP recurrence (OR=2.404, P=0.030), ALT ≥200 U/L (OR=2.051, P=0.018), comorbidity with GDM (OR=1.944, P=0.029), and TBA ≥40 μmol/L (OR=2.542, P=0.024). The syndrome of blood deficiency generating wind syndrome was associated with maternal age ≥35 years (OR=2.939, P=0.003), parity ≥2 time (OR=3.222, P=0.003), history of ICP recurrence (OR=3.809, P=0.010), ALT ≥200 U/L (OR=2.889, P=0.006), comorbidity with GDM (OR=3.711, P=0.001), and comorbidity with hypertensive disorders of pregnancy (OR=4.472, P=0.011). Liver depression and spleen deficiency syndrome was associated with TBA ≥40 μmol/L (OR=2.995, P=0.044). The analysis of perinatal outcomes showed that there were significant differences in mode of delivery, gestational weeks at the time of delivery, postpartum blood loss, and neonatal birth weight between the three groups with different TCM syndromes (all P<0.05). ConclusionLiver-gallbladder damp-heat syndrome, syndrome of blood deficiency generating wind, and liver depression and spleen deficiency syndrome are the main TCM syndrome types in ICP, and the distribution of TCM syndromes is closely associated with clinical factors and perinatal outcomes, which provides a basis for precise TCM syndrome differentiation and individualized treatment.

Objective:To investigate the effects of marathon exercise on knee cartilage volume and T2 relaxation time (T2 value) based on MRI.Methods:From December 2018 to December 2021, 25 healthy volunteers without long-distance running habits and 32 non-professional marathon runners with long-term long-distance running were recruited to undergo knee MRI 3D water-selective excitation (three dimensional water-selective excitation, 3D-WATS) and T2 mapping imaging were performed, and the cartilage volumes in 5 knee areas and T2 values in 42 subareas were extracted for analysis. To compare the cartilage volume and its ratio to body surface area of knee joint of healthy volunteers and non-professional marathon runners, the T2 value of cartilage in each subregion, and the correlation between marathon exercise intensity and the volume and T2 value of cartilage in different regions.Results:Compared with healthy volunteers, there was no significant difference in cartilage volume or the ratio of body surface area to body volume of non-professional marathon runners ( P>0.05). There were significant differences between healthy volunteers and non-professional marathon runners in cartilage T2 values of the median layer of medial condyle of femur (47.61±5.65 ms and 44.29±6.10 ms) and the deep layer of medial condyle of femur (36.82±9.05 ms and 31.67±7.59 ms), deep precondylar area of medial femur (38.37±4.68 ms and 34.09±4.19 ms), shallow area of medial condylar area of femur (52.17±11.11 ms and 45.51±7.76 ms), middle layer of medial condylar area of femur (49.09±5.08 ms and 45.63±5.04 ms), medial layer of anterior condylar region of lateral femur (45.69±4.68 ms and 42.57±5.77 ms), superficial layer of posterior condylar region of lateral femur (55.42±18.41 ms and 47.99±8.39 ms), deep layer of anterior tibial medial plateau (33.40±7.76 ms and 29.03±5.69 ms), deep layer of posterior tibial medial plateau (31.28±5.02 ms and 27.92±5.99 ms), deep layer of patellofemoral surface (35.65±6.99 ms and 32.30±5.28 ms), respectively ( P<0.05). In non-professional marathon runners, the medial tibial plateau cartilage volume was negatively correlated with step frequency ( r=-0.371, P=0.035), the lateral femoral condylar cartilage volume was negatively correlated with step frequency ( r=-0.365, P=0.043), and the lateral tibial plateau cartilage volume was negatively correlated with step frequency ( r=-0.550, P=0.001). The T2 value of the medial layer cartilage in the anterior tibial medial plateau region was negatively correlated with body weight ( r=-0.277, P=0.039) and body mass index ( r=-0.290, P=0.030). The T2 value of the superficial layer of patellofemoral surface was negatively correlated with the amount of running in 3 months ( r=-0.457, P=0.010). The superficial T2 value in the posterior lateral plateau of the tibia was negatively correlated with stride length ( r=-0.437, P=0.014), and the medial layer cartilage T2 value in the anterior condylar area of the lateral femur was negatively correlated with stride frequency ( r=-0.380, P=0.035). Conclusion:Marathon exercise had little effect on the knee cartilage volume, but had a certain effect on the cartilage T2 value, resulting in changes in cartilage structure. The higher the step frequency, the smaller the cartilage volume. The greater the body weight or body mass index, the greater the amount of running in 3 months, and the greater the stride length, the lower the cartilage T2 value.
