To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Extracorporeal circulation serves as a vital auxiliary approach in cardiac surgery, and its introduction and application have directly driven a clinical revolution in cardiac surgical procedures. With the continuous advancement of clinical techniques in cardiac surgery, extracorporeal circulation technology has undergone constant innovation. To align with the trend of minimally invasive surgery, minimally invasive extracorporeal circulation (MiECC) technology has emerged. Its feasibility and safety have been preliminarily verified in clinical practice. This paper synthesizes domestic and international literature to expound on the development of MiECC and its advantages in clinical applications, aiming to further promote its adoption in China.

Objective: To analyze the epidemiological characteristics, etiological distribution and risk factors of recurrent hand, foot and mouth disease (HFMD) in Jiaxing City, so as to provide scientific evidence for developing targeted prevention and control strategies. Methods: Based on the China Disease Prevention and Control Information System, data of all reported HFMD cases in Jiaxing City from January 1, 2016 to December 31, 2024 were collected. Epidemiological and etiological distribution characteristics of recurrent HFMD cases were described. The Kaplan-Meier method was applied to estimate the cumulative risk probability of reinfection, and the Cox proportional hazards regression model was used to identify risk factors for HFMD reinfection. Results: A total of 3 105 recurrent HFMD cases were reported in Jiaxing City during 2016-2024, with a reinfection rate of 3.99%. The majority of reinfections were second episodes (97.68%). HFMD reinfection was associated with sex, age, population category and etiological serotype ( χ 2=26.44, 609.92, 459.72, 32.01, all P <0.01). The incidence of recurrent HFMD exhibited a bimodal seasonal pattern, with peaks occurring from June to July and September to November. Spatial distribution indicated that Nanhu District, Jiashan County and Tongxiang City accounted for 49.02% of all recurrent cases citywide. Among 264 laboratory confirmed recurrent cases, EV-A71 was the predominant pathogen (29.92%). The proportion of EV-A71 showed a trend of initial decline followed by rebound, while the proportion of CV-A6 increased over time ( χ 2 trend =6.94, 47.43, both P <0.05). Of 51 patients with ≥2 etiological test results, 56.86 % experienced reinfection with a different serotype. The median time to HFMD reinfection was 17.23 (0.50, 105.03) months after the primary episode. The reinfection probability was 0.61% at 6 months, 3.68% at 36 months, and remained approximately 5% at 64.37 months. Multivariate Cox regression revealed that male sex ( HR =1.23), age ≤ 3 years ( HR = 1.84), and scattered children and preschool children ( HR =3.78, 3.47, respectively) were independent risk factors for HFMD reinfection (all P <0.05). Conclusions Recurrent HFMD in Jiaxing City presents temporal and population heterogeneity, and its etiology shows an alternating serotype evolution pattern. Enhanced surveillance should be implemented among priority populations and high incidence regions, and multivalent vaccines should be developed to confer broader protection.

As an extension of the central nervous system, the retina is the only tissue in the body that allows direct in vivo observation of both neural and vascular structures, offering a unique non-invasive window for the assessment of cerebral neurovascular diseases. Recent studies have shown that multimodal imaging techniques—such as fundus photography, optical coherence tomography(OCT), and OCT angiography(OCTA)—enable quantitative analysis of retinal indicators including vascular caliber, fractal dimension, retinal nerve fiber layer thickness, and microvascular density. These metrics can, to some extent, reflect the severity and progression risk of cerebrovascular and neurodegenerative diseases such as stroke, Alzheimer's disease, and Parkinson's disease. Consequently, retinal imaging holds promise as a powerful tool for early screening, risk stratification, and treatment monitoring. This article systematically reviews the application of retinal imaging technologies in the diagnosis and management of cerebral neurovascular disorders, with a particular focus on the important role of artificial intelligence(AI)-driven image analysis in enhancing screening efficiency, improving risk assessment accuracy, and promoting multidisciplinary collaborative care, thereby providing insights for clinical translation.

ObjectiveTo investigate the mechanism of action of modified Shaofu Zhuyutang in antagonizing cellular pyroptosis and fibrosis in ectopic endometrial tissues of endometriosis through the Toll-like receptor 4/nuclear factor-κB/NOD-like receptor protein 3 （TRL4/NF-κB/NLPR3） signaling pathway. MethodsSeventy-two SPF-grade female SD rats were randomly divided into a sham-operated group （n = 12） and a modeling group （n = 60）. The rats in the sham-operated group underwent a caesarean section， while the rats in the modeling group were used to establish an endometriosis model through the auto-transplantation method. After successful modeling， the animals were randomly divided into the model group， progesterone group （0.25 mg·kg^-1）， and modified Shaofu Zhuyutang low-， medium-， and high-dose groups （7.5， 15， 30 g·kg^-1）， with 12 animals in each group. After 4 weeks of drug administration， voluntary activity and heat pain latency were observed. The rats were sacrificed for tissue collection， and Masson staining were used to observe histopathological changes in the endometrial tissues. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of interleukin-18 （IL-18）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and transforming growth factor-β （TGF-β）. Immunohistochemistry （IHC） was used to detect the protein expression area of tumor necrosis factor-related factor 6 （TRAF6） and NLPR3 in the endometrial tissues. Immunofluorescence （IF） was used to detect the relative fluorescence intensity of Caspase-1 and gasdermin D （GSDMD） in the endometrial tissues. Western blot was employed to measure the relative expression of TRL4， myeloid differentiation factor 88 （MyD88）， TRAF6， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， and NLPR3 proteins in endometrial tissues. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 in the endometrial tissues. ResultsCompared with the sham-operated group， rats in the model group showed reduced voluntary activity and shorter heat pain latency. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were elevated. The relative expression areas of TRAF6 and NLPR3 proteins were increased， and the relative fluorescence intensity of Caspase-1 and GSDMD was enhanced. The relative expression of TRL4， MyD88， TRAF6， NF-κB p65， p-NF-κB p65， and NLPR3 proteins， along with the expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA， were significantly increased （P<0.01）. Compared with the model group， rats in the progesterone group and the modified Shaofu Zhuyutang medium- and high-dose groups exhibited improved voluntary activity， longer heat pain latency， the fibrosis of endometrial tissue is alleviated. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were decreased. The relative expression areas of TRAF6 and NLPR3 proteins decreased， and the relative fluorescence intensity of Caspase-1 and GSDMD weakened. The relative expression of TRL4， MyD88， TRAF6， p-NF-κB p65， NLPR3 proteins， and TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA expression were reduced （P<0.05， P<0.01）. ConclusionModified Shaofu Zhuyutang may play a therapeutic role in endometriosis by interfering with key proteins in the TRL4/NF-κB/NLPR3 signaling pathway， reducing NLRP3 inflammasome-induced cellular pyroptosis， antagonizing the fibrosis process in ectopic endometrial tissues， improving the inflammatory microenvironment in the pelvic cavity， and alleviating pain.

ObjectiveTo observe the effects of modified Shaofu Zhuyutang on key proteins of the epidermal growth factor receptor （EGFR）/phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway in SD rats with endometriosis. MethodsAfter successful establishment of an endometriosis model in 60 female SD rats of SPF grade via the auto-transplantation method， the rats were randomly divided into a model group， modified Shaofu Zhuyutang high-， medium-， and low-dose groups， and a gestrinone group， with another 12 rats serving as a blank group. The blank and model groups were administered 10 mL·kg^-1 normal saline， while the high-， medium-， and low-dose groups received 30， 15， and 7.5 g·kg^-1 modified Shaofu Zhuyutang， respectively. The gestrinone group was administered 0.25 mg·kg^-1 gestrinone suspension. After four weeks of treatment， uterine contractions were induced with 2 U of oxytocin， and the writhing response of rats was observed. After 24 h， the rats were euthanized， and the weight and volume of ectopic endometrial tissue were recorded. Hematoxylin-eosin （HE） staining was used to observe pathological changes in endometrial tissues， while the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling （TUNEL） assay was used to evaluate the apoptosis rate of endometrial tissues. Immunofluorescence was used to detect the relative expression areas of the B-cell lymphoma-2 gene-associated promoter （Bad） and B-cell lymphoma-2 （Bcl-2） proteins in endometrial tissues. Serum levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， epidermal growth factor （EGF）， and EGFR were measured by enzyme-linked immunosorbent assay （ELISA）. The relative protein expression levels of EGFR， PI3K， phosphorylated PI3K （p-PI3K）， Akt， and phosphorylated Akt （p-Akt） in endometrial tissues were analyzed by Western blot. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of EGFR， PI3K， and Akt. ResultsCompared with the blank group， the model group showed endometrial thickening， glandular and mesenchymal hyperplasia， a significant decrease in the relative expression area of Bad in ectopic endometrial tissues， a significant increase in the relative expression area of Bcl-2， and a significant reduction in the apoptosis rate as indicated by TUNEL staining. Serum levels of IL-1β， IL-6， TNF-α， EGF， and EGFR were significantly elevated （P<0.01）. The relative protein expression levels of EGFR， PI3K， p-PI3K， Akt， and p-Akt， as well as the mRNA expression levels of EGFR， PI3K， and Akt， were also significantly increased （P<0.01）. Compared with the model group， the high- and medium-dose groups of modified Shaofu Zhuyutang and the gestrinone group exhibited reduced glandular and mesenchymal hyperplasia to varying degrees， with dilated glandular lumens. The number of writhing responses was significantly reduced， the latency to writhing response was significantly prolonged， and the weight and volume of ectopic endometrial tissue were significantly decreased. The relative expression area of Bad in ectopic endometrial tissue was significantly increased， the relative expression area of Bcl-2 was significantly decreased， and the apoptosis rate was significantly elevated as shown by TUNEL staining. Serum levels of IL-1β， IL-6， TNF-α， EGF， and EGFR were significantly reduced， and the relative protein expression levels of EGFR， PI3K， p-PI3K， Akt， and p-Akt， as well as the mRNA expression levels of EGFR， PI3K， and Akt， were significantly decreased （P<0.05，P<0.01）. ConclusionModified Shaofu Zhuyutang may exert therapeutic effects on endometriosis by interfering with key proteins of the EGFR/PI3K/Akt signaling pathway and inducing apoptosis in ectopic endometrial tissue.

ObjectiveTo investigate the mechanism of modified Shaofu Zhuyutang in inducing ferroptosis in ectopic endometrial tissues of rats with endometriosis through the murine double minute 4 （MDM4）/tumor suppressor p53/glutathione peroxidase 4 （GPX4） signaling pathway. MethodsSeventy SPF-grade female SD rats were randomly divided into a blank group （n = 10）， a sham-operated group （n = 10）， and a modeling group （n = 50）. The sham-operated group underwent laparotomy， while the modeling group was subjected to the autotransplantation method to establish an endometriosis model. After successful modeling， the animals were randomly assigned to the model group， progesterone group （0.25 mg·kg^-1）， and modified Shaofu Zhuyutang high-， medium-， and low-dose groups （30， 15， and 7.5 g·kg^-1， respectively）， with 10 rats per group. After four weeks of drug administration， the rats were euthanized for sample collection. The weight and volume of ectopic endometrial tissues were recorded for each group. Transmission electron microscopy （TEM） was employed to observe ultrastructural changes in endometrial tissues， while Prussian blue staining was used to assess iron ion deposition. Serum levels of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） were measured by enzyme-linked immunosorbent assay （ELISA）. The relative levels of Fe²⁺， malondialdehyde （MDA）， and glutathione （GSH） in endometrial tissues were determined by colorimetric assay. Immunofluorescence （IF） was used to detect the relative fluorescence intensities of GSH and GPX4 in endometrial tissues. The relative expression levels of phosphatidylinositol 3-kinase （PI3K）， phosphorylated PI3K （p-PI3K）， protein kinase B （Akt）， phosphorylated Akt （p-Akt）， MDM4， p53， and GPX4 proteins were detected by Western blot. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to assess the mRNA expression of PI3K， Akt， MDM4， p53， and GPX4. ResultsCompared with the blank and sham-operated groups， the model group exhibited reduced ferroptotic damage in ultrastructural observations， decreased ferroptotic aggregates and positive iron ion expression area on Prussian blue staining， elevated serum IL-6， IL-1β， and TNF-α levels， reduced Fe²⁺ and MDA content， increased GSH content in endometrial tissues， and enhanced GSH and GPX4 fluorescence intensities （P<0.01）. The protein and mRNA expression levels of PI3K， p-PI3K， Akt， p-Akt， MDM4， and GPX4 were elevated， while those of p53 were decreased （P<0.01）. Compared with the model group， in the progesterone group and the modified Shaofu Zhuyutang high- and medium-dose groups， ferroptotic damage in ultrastructural observations was exacerbated to varying degrees by TEM， and ferroptotic aggregates and positive iron ion expression areas were increased on Prussian blue staining. Serum IL-6， IL-1β， and TNF-α levels decreased， Fe²⁺ and MDA content increased， and GSH content decreased in endometrial tissues. GSH and GPX4 fluorescence intensities weakened， while the protein and mRNA expression levels of PI3K， p-PI3K， Akt， p-Akt， MDM4， and GPX4 decreased， and those of p53 increased （P<0.05， P<0.01）. Conclusionmodified Shaofu Zhuyutang may exert therapeutic effects in endometriosis by inducing ferroptosis in ectopic endometrial tissues， alleviating inflammatory responses， and modulating key proteins in the MDM4/p53/GPX4 signaling pathway.

ObjectiveTo explore the mechanism by which modified Shaofu Zhuyutang inhibits angiogenesis in endometriosis via the vascular endothelial growth factor （VEGF）/phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/endothelial nitric oxide synthase （eNOS）-nitric oxide （NO） signaling pathway. MethodsEighty-four female SD rats were randomly assigned into blank， sham operation， model， positive control （gestrinone， 0.25 mg·kg^-1）， high-， medium-， and low-dose （30， 15， 7.5 g·kg^-1， respectively） traditional Chinese medicine （TCM， modified Shaofu Zhuyutang） groups. A rat model of endometriosis was established by the autotransplantation method. After successful modeling， rats in the drug intervention groups were administrated with corresponding agents by gavage， and those in the blank， sham operation， and model groups received an equal volume of distilled water. After 28 days of gavage， rats were administrated with oxytocin， and the number and latency period of writhing responses were observed. Serum samples from each group， ectopic lesions from modeling groups， and uteri from blank and sham operation groups were collected. Hematoxylin-eosin staining was used to observe the pathological morphology of endometriotic lesions. Immunohistochemistry was employed to observe the expression of angiogenesis-specific markers cluster of differentiation 34 antigen （CD34） and friend leukemia virus integration-1 （FLI-1）. Enzyme-linked immunosorbent assay and the nitrate reductase method were employed to determine the serum levels of VEGF and NO， respectively. Western blot was employed to measure the protein levels of VEGF， PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， eNOS， and phosphorylated eNOS （p-eNOS）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was conducted to determine the mRNA levels of VEGF， PI3K， Akt， and eNOS. ResultsThe blank group and the sham operation group had no significant changes in the number and latency period of writhing responses， serum VEGF and NO levels， protein levels of VEGF， p-PI3K/PI3K， p-Akt/Akt， and p-eNOS/eNOS， and mRNA levels of VEGF， PI3K， Akt， and eNOS. The model group showed an increase in the number and a reduction in the latency period of writhing responses， enlargement of ectopic endometrial tissue in the abdominal wall， with stromal hyperplasia， glandular dilation， and increased vasculature. In addition， the modeling led to increased positive expression of CD34 and FLI-1， elevated serum VEGF and NO levels， and up-regulated protein levels of VEGF， p-PI3K/PI3K， p-Akt/Akt， and p-eNOS/eNOS and mRNA levels of VEGF， PI3K， Akt， and eNOS （P<0.01）. Compared with the model group， the gestrinone and high-， medium-， and low-dose TCM groups showed a significant reduction in the number of writhing responses， a significant prolongation of the latency period， reduced ectopic endometrial tissue in the abdominal wall， alleviated pathological damage， and reduced positive expression of CD34 and FLI-1. The gestrinone group and the high- and medium-dose TCM groups showed lowered serum VEGF and NO levels as well as down-regulated protein levels of VEGF， p-PI3K/PI3K， p-Akt/Akt， and p-eNOS/eNOS and mRNA levels of VEGF， PI3K， Akt， and eNOS. Moreover， the low-dose TCM group showed reductions in the serum VEGF level， the protein levels of VEGF， p-PI3K/PI3K， p-Akt/Akt， and p-eNOS/eNOS， and the mRNA levels of VEGF and eNOS （P<0.05， P<0.01）. ConclusionModified SShaofu Zhuyutang can inhibit angiogenesis in endometriosis by antagonizing the abnormal activation of the VEGF/PI3K/Akt/eNOS-NO signaling pathway， thereby preventing the occurrence， development， and deterioration of endometriosis.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.
