Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Obstetric antiphospholipid syndrome(OAPS)is an autoimmune disorder associated with various pathological pregnancies,such as recurrent miscarriage,stillbirth,severe pre-eclampsia and severe placental insufficiency.The persistent presence of antiphospholipid antibodies(aPLs)is the most important laboratory characteristic of OAPS.OAPS severely affects the reproductive health of women of childbearing age in China.Reports indicate that approximately 9.6% stillbirths,11.5% severe pre-eclampsia,and 54% recurrent miscarriages are associated with OAPS or aPLs.However,the pathogenesis of OAPS remains unclear.Previously,thrombosis at the maternal-fetal interface(MFI)was considered the main mechanism of OAPS-related pathological pregnancies.Consequently,the use of low molecular weight heparin and aspirin throughout pregnancy was recommended to improve outcomes in OAPS patient.In recent years,many studies have found that thrombosis in MFI is uncommon,but various inflammatory factors are significantly increased in the MFI of OAPS patients.Based on these findings,some clinicians have started using anti-inflammatory treatments for OAPS,which have preliminarily improved the pregnancy outcomes.Nevertheless,there is no consensus on these second-line treatments of OAPS.Another troubling issue is the clinical diagnosis of OAPS.Similar to other autoimmune diseases,there are only classification criteria for OAPS,and clinical diagnosis of OAPS depends on the clinicians'experience.The present classification criteria of OAPS were established for clinical and basic research purposes,not for patient clinical management.In clinical practice,many patients with both positive aPLs and pathological pregnancy histories do not meet the strict OAPS criteria.This has led to widespread issues of incorrect diagnosis and treatment.Timely and accurate diagnosis of OAPS is crucial for effective treatment.In this article,we reviewed the epidemiological research progress on OAPS and summarized its classification principles,including:1)the persistent presence of aPLs in circulation;2)manifestations of OAPS,excluding other possible causes.For the first point,accurate assessment of aPLs is crucial;for the latter,previous studies regarded only placenta-related pregnancy complications as characteristic manifestations of OAPS.However,recent studies have indicated that adverse pregnancy outcomes related to trophoblast damage,such as recurrent miscarriage and stillbirth,also need to be considered in OAPS.We also discussed several key issues in the diagnosis and treatment of OAPS.First,we addressed the definition of non-standard OAPS and offered our opinion on defining non-standard OAPS within the framework of the 2023 American College of Rheumatology(ACR)/European League Against Rheumatism(EULAR)APS criteria.Then,we discussed the advantages and disadvantages of different aPL testing methods,emphasizing that harmonizing results across platforms and establishing specific reference values are keys to resolving controversies in aPL testing results.We also introduced the application of non-criteria aPLs,especially anti-phosphatidylserine/prothrombin antibody(aPS/PT)and anti-β2 glycoprotein Ⅰ domain Ⅰ antibody(aβ2GPⅠDⅠ).Additionally,we discussed aPL-based OAPS risk classification strategies.Finally,we proposed potential treatment methods for refractory OAPS.The goal is to provide a reference for the clinical management of OAPS.

Objective: To evaluate the efficacy and safety of Nocardia rubra cell wall skeleton (Nr-CWS) in the treatment of persistent cervical high-risk human papillomavirus (HR-HPV) infection. Methods: A randomized, double blind, multi-center trial was conducted. A total of 688 patients with clinically and pathologically confirmed HR-HPV infection of the cervix diagnosed in 13 hispital nationwide were recruited and divided into: (1) patients with simple HR-HPV infection lasting for 12 months or more; (2) patients with cervical intraepithelial neoplasia (CIN) Ⅰ and HR-HPV infection lasting for 12 months or more; (3) patients with the same HR-HPV subtype with no CINⅡ and more lesions after treatment with CINⅡ or CIN Ⅲ (CINⅡ/CIN Ⅲ). All participants were randomly divided into the test group and the control group at a ratio of 2∶1. The test group was locally treated with Nr-CWS freeze-dried powder and the control group was treated with freeze-dried powder without Nr-CWS. The efficacy and negative conversion rate of various subtypes of HR-HPV were evaluated at 1, 4, 8, and 12 months after treatment. The safety indicators of initial diagnosis and treatment were observed. Results: (1) This study included 555 patients with HR-HPV infection in the cervix (included 368 in the test group and 187 in the control group), with an age of (44.1±10.0) years. The baseline characteristics of the two groups of subjects, including age, proportion of Han people, weight, composition of HR-HPV subtypes, and proportion of each subgroup, were compared with no statistically significant differences (all P>0.05). (2) After 12 months of treatment, the effective rates of the test group and the control group were 91.0% (335/368) and 44.9% (84/187), respectively. The difference between the two groups was statistically significant (χ²=142.520, P<0.001). After 12 months of treatment, the negative conversion rates of HPV 16, 18, 52, and 58 infection in the test group were 79.2% (84/106), 73.3% (22/30), 83.1% (54/65), and 77.4% (48/62), respectively. The control group were 21.6% (11/51), 1/9, 35.1% (13/37), and 20.0% (8/40), respectively. The differences between the two groups were statistically significant (all P<0.001). (3) There were no statistically significant differences in vital signs (body weight, body temperature, respiration, pulse rate, systolic blood pressure, diastolic blood pressure, etc.) and laboratory routine indicators (blood cell analysis, urine routine examination) between the test group and the control group before treatment and at 1, 4, 8, and 12 months after treatment (all P>0.05); there was no statistically significant difference in the incidence of adverse reactions related to the investigational drug between the two groups of subjects [8.7% (32/368) vs 8.0% (15/187), respectively; χ²=0.073, P=0.787]. Conclusion: External use of Nr-CWS has good efficacy and safety in the treatment of high-risk HPV persistent infection in the cervix.

OBJECTIVE To observe the effects of chlorogenic acid on the activation of macrophage induced by lipopolysaccharide （LPS）， and to explore the role of triggering receptors expressed on myeloid cells-2 （TREM2） in the action. METHODS To find a suitable LPS concentration， the cells were cultured with 1， 10 and 100 ng/mL LPS for 24 h. The level of interleukin 6 （IL-6） in the cell culture supernatant and protein expression of inducible nitric oxide synthase （iNOS） in the cells were detected. To search for a suitable chlorogenic acid concentration， the cells were divided into control group， LPS group and three chlorogenic acid （0.01， 0.1 and 1 μmol/L）+LPS groups. The levels of tumor necrosis factor α （TNF-α） and IL-1β in the cell culture supernatant， the protein expressions of iNOS and TREM2 in the cells and cell viability were detected. To observe the effects of TREM2 in chlorogenic acid alleviating macrophage activation， TREM2-small interfering RNA （TREM2-siRNA） was taken to intervene in TREM2 protein expression. The cells were divided into control group， LPS group， chlorogenic acid+LPS group， TREM2-siRNA+chlorogenic acid+LPS group and SC-siRNA+chlorogenic acid+LPS group. After 24 h incubation， the levels of TNF- α and IL-1β in the cell culture supernatant and protein expressions of TREM2， iNOS and nuclear factor κB p65 （NF-κB p65） in the cells were detected. RESULTS 10 ng/mL LPS promoted IL-6 release and increased iNOS protein expression， and 10 ng/mL LPS was taken in the next experiments. Compared with the LPS group， 0.1 μmol/L chlorogenic acid decreased TNF-α jiaji1981@126.com and IL-1β levels， and down-regulated iNOS expression，meanwhile increased TREM2 expression without effect on cell viability， and 0.1 μmol/L chlorogenic acid was taken in the next experiments. Compared with the control group， the protein expressions of iNOS and NF- κB p65 in the LPS group were significantly increased （P＜0.05）； compared with the LPS group， the protein expressions of iNOS and NF- κB p65 in the chlorogenic acid+LPS group were significantly decreased， the protein expressions of TREM2 was significantly increased （P＜ 0.05）； compared with the chlorogenic acid+LPS group， the protein expressions of iNOS and NF-κB p65 of TREM2-siRNA+ chlorogenic acid+LPS group were significantly increased， the protein expressions of TREM2 was significantly decreased （P＜0.05）. TREM2-siRNA could significantly reverse the above effects of chlorogenic acid， while SC-siRNA did not significantly affect the above anti-inflammatory effects of chlorogenic acid. CONCLUSIONS Chlorogenic acid can inhibit the LPS-induced macrophage activation， and its anti-inflammatory may be mediated by TREM2 protein.

Objective To investigate the effects of paclitaxel and doxorubicin on the immune microenvironment of breast cancer in mice. Methods The CTR-DB database, a database for analysis of gene expression profiles and drug resistance characteristics related to tumor drug response, was used to analyze the effect of chemotherapeutic drugs on the immune microenvironment of breast cancer. Mouse models with breast cancer were established by in situ injection with 4T1 cells, a triple-negative breast cancer (TNBC) cells. Then they were treated with doxorubicin and paclitaxel, respectively. The sizes of tumor were recorded and analyzed by growth curve. The number of different types of immune cells was analyzed using flow cytometry. The expressions of Ki67, S100 calcium binding protein A9 (S100A9) and matrix metalloproteinase 9 (MMP9) were detected by immunohistochemistry. The cell cycles of 4T1 cells in paclitaxel group and doxorubicin group were analyzed by flow cytometry. Results The results of CTR_Microarray_75 analysis showed that the immune scores, and the number of cytotoxic lymphocytes, B lineages, CD8⁺ T cells, dendritic cells (DCs), monocytic lineages and natural killer (NK) cells in chemotherapy-sensitive breast cancer were higher than those in chemotherapy-insensitive breast cancer. Through growth curve analysis in mice with breast cancer, we found that both paclitaxel and doxorubicin could inhibit the increase of the tumor sizes, and the paclitaxel showed a higher inhibitory effect. The results of cytometry displayed that both paclitaxel and doxorubicin could restrain the expression of Ki67 and increase the number of breast cancer cells in G2/M phase, and in the paclitaxel group, the expression of Ki67 was lower and the number of breast cancer cells in G2/M phase was larger. Paclitaxel and doxorubicin enhanced the infiltration of CD45⁺ immune cells but decreased the infiltration of neutrophils. Additionally, paclitaxel promoted the infiltration of CD3⁺CD4⁺ T helper cells, CD3⁺CD8⁺ cytotoxic T cells and CD45⁺CD19⁺B cells, while doxorubicin increased the infiltration of CD4⁺CD25⁺ regulatory T cells (Tregs). The results of immunohistochemistry displayed that the paclitaxel significantly inhibited the expression of S100A9, while the doxorubicin significantly restrained the expression of MMP9. Conclusion Paclitaxel and doxorubicin can effectively inhibit the growth of breast cancer cells and change immune microenvironment of TNBC by regulating the different patterns of cell infiltration and the expression of different extracellular matrix components.

BACKGROUND: Tri-ponderal mass index (TMI) has been reported to be a more accurate estimate of body fat than body mass index (BMI). This study aims to compare the effectiveness of TMI and BMI in identifying hypertension, dyslipidemia, impaired fasting glucose (IFG), abdominal obesity, and clustered cardio-metabolic risk factors (CMRFs) in 3- to 17-year-old children. METHODS: A total of 1587 children aged 3 to 17 years were included. Logistic regression was used to evaluate correlations between BMI and TMI. Area under the curves (AUCs) were used to compare discriminative capability among indicators. BMI was converted to BMI- z scores, and accuracy was compared by false-positive rate, false-negative rate, and total misclassification rate. RESULTS: Among children aged 3 to 17 years, the mean TMI was 13.57 ± 2.50 kg/m 3 for boys and 13.3 ± 2.33 kg/m 3 for girls. Odds ratios (ORs) of TMI for hypertension, dyslipidemia, abdominal obesity, and clustered CMRFs ranged from 1.13 to 3.15, higher than BMI, whose ORs ranged from 1.08 to 2.98. AUCs showed similar ability of TMI (AUC: 0.83) and BMI (AUC: 0.85) in identifying clustered CMRFs. For abdominal obesity and hypertension, the AUC of TMI was 0.92 and 0.64, respectively, which was significantly better than that of BMI, 0.85 and 0.61. AUCs of TMI for dyslipidemia and IFG were 0.58 and 0.49. When 85th and 95th of TMI were set as thresholds, total misclassification rates of TMI for clustered CMRFs ranged from 6.5% to 16.4%, which was not significantly different from that of BMI- z scores standardized according to World Health Organization criteria. CONCLUSIONS TMI was found to have equal or even better effectiveness in comparison with BMI in identifying hypertension, abdominal obesity, and clustered CMRFs TMI was more stable than BMI in 3- to 17-year-old children, while it failed to identify dyslipidemia and IFG. It is worth considering the use of TMI for screening CMRFs in children and adolescents.

PURPOSE: Child head injury under impact scenarios (e.g. falls, vehicle crashes, etc.) is an important topic in the field of injury biomechanics. The head of piglet was commonly used as the surrogate to investigate the biomechanical response and mechanisms of pediatric head injuries because of the similar cellular structures and material properties. However, up to date, piglet head models with accurate geometry and material properties, which have been validated by impact experiments, are seldom. We aim to develop such a model for future research. METHODS: In this study, first, the detailed anatomical structures of the piglet head, including the skull, suture, brain, pia mater, dura mater, cerebrospinal fluid, scalp and soft tissue, were constructed based on CT scans. Then, a structured butterfly method was adopted to mesh the complex geometries of the piglet head to generate high-quality elements and each component was assigned corresponding constitutive material models. Finally, the guided drop tower tests were conducted and the force-time histories were ectracted to validate the piglet head finite element model. RESULTS: Simulations were conducted on the developed finite element model under impact conditions and the simulation results were compared with the experimental data from the guided drop tower tests and the published literature. The average peak force and duration of the guide drop tower test were similar to that of the simulation, with an error below 10%. The inaccuracy was below 20%. The average peak force and duration reported in the literature were comparable to those of the simulation, with the exception of the duration for an impact energy of 11 J. The results showed that the model was capable to capture the response of the pig head. CONCLUSION This study can provide an effective tool for investigating child head injury mechanisms and protection strategies under impact loading conditions.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.
