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.

Following the release of the Technical Requirements on Quality Control and Standard Establishment of Traditional Chinese Medicine Formula Granules by the National Medical Products Administration in 2021, Chinese Pharmacopoeia Commission has promulgated 296 national drug standards so far, and most provinces have started the work of establishing provincial standards as supplements. The promulgation of standards fostered high-quality development of the industry. Since the implementation of national and provincial standards for more than three years, enterprises have gained deep understanding and hands-on experiences on the characteristics, technical requirements, production process, and quality control of traditional Chinese medicine(TCM) formula granules. Meanwhile, challenges have emerged restricting the high-quality development of this industry, including how to formulate quality control strategies for medicinal materials and decoction pieces, how to reduce manufacturing costs, and how to improve the pass rate and product stability under high standards. Based on the work experiences from standard management and process research, this article analyzed the distribution of sources, processing methods, dry extract rate ranges, process requirements for volatile oil-containing decoction pieces, control measures of safety indices, characteristics and trends of setting characteristic chromatograms or fingerprints, characteristics and trends of setting content ranges, and main differences between national standards and provincial standards. On the one hand, this article aims to present main characteristics for deeply understanding different indicators in standards and provide basic ideas for establishing quality and process control systems. On the other hand, from the perspective of industrial practice, suggestions are put forward on the important aspects that need to be focused on in the quality and process control of TCM formula granules.

Objective To analyze the causal relationship between brain resting state functional magnetic resonance imaging(rsfMRI)network and myocardial infarction using the Mendelian randomization(MR)research method.Methods Four analytical methods of MR[inverse-variance weighted(IVW),weighted median method(WME),weighted mode method,and MR-Egger method]were used to conduct a two-way two-sample analysis between 191 types of rsfMRI phenotypes of the brain(34 691 types)and myocardial infarction.And based on the aggregated analysis of genome-wide association studies(GWAS)data,MR was used to explain the causal relationship between the two.Then,the IVW method was used for analysis and research as the main result,and other analytical methods were used as supplementary analyses.Finally,the credibility of the results was verified by using sensitivity analysis.Results The neural connection activities located at the edge of the fusiform gyrus of the temporal lobe and the default mode network[odds ratio(OR)=1.260,95%confidence interval(95%CI)1.120-1.420,P<0.001]may increase the risk of myocardial infarction.In addition,the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus,and cerebellum(OR=0.770,95%CI was 0.680-0.880,P<0.001),and the subcortical cerebellar and motor networks located in the cerebellum and paracentric lobules(OR=0.810,95%CI was 0.720-0.900,P<0.001)and the neural connection activities of the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and subcortex(OR=0.730,95%CI was 0.630-0.840,P<0.001)were associated with a reduced risk of myocardial infarction.Sensitivity analysis showed that the research results were reliable,and after the reverse MR study,it was confirmed that there was no reverse causal association between the two.Conclusion The network signals located at the edge of the fusiform gyrus of the temporal lobe and in the default mode may be potential risk factors for myocardial infarction;the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and cerebellum,as well as the subcortical cerebellar and motor networks located in the cerebellum and paracentric lobules,and the neural connection activities of the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and subcortex may be potential protective factors,providing new ideas for the prevention and treatment of myocardial infarction.

Objective:To explore the mechanism for the occurrence and phenotypic characteristics of Turner syndrome based on a prenatally diagnosed case of a mosaic karyotype containing double pseudo-isodicentric X chromosome and a review of relevant literature.Methods:A fetus who was diagnosed with increased risk of trisomy 21 at the Provincial Hospital Affiliated to Shandong First Medical University in August 2023 was selected as the study subject. Clinical data of the fetus was collected. Following amniocentesis, chromosomal G-banding karyotype analysis and chromosomal microarray analysis (CMA) were carried out. This study has been approved by the Ethics Committee of the Hospital (Ethics No.: SWYX No. 2022-287).Results:The early-trimester screening suggested a high risk of trisomy 21(1/19), with free β-hCG of 116 ng/mL (MoM value 2.35), PAPP-A of 0.394 ng/mL (MoM value 0.12), and NT value of 1.3 mm, though no abnormality was found in the fetus at 19 weeks gestation. The karyotype of amniocyte was determined as 46, X, psu idic(X)(p11.21)[55]/45, X[27]/47, X, psu idic(X)(p11.21)×2[5]/46, XX[13]. CMA has yielded a result of arr[GRCh37] Xp22.33p11.21(168552_55585678)×1[0.67], Xp11.21q28(55703291_155233098)×3[0.5].Conclusion:Karyotypes of Turner syndrome are complex and diverse, and a rare 46, X, psu idic(X)(p11.21)[55]/45, X[27]/47, X, psu idic(X)(p11.21)×2[5]/46, XX[13] mosaic karyotype with double pseudo-isodicentric X chromosome has been identified. Literature review suggested that this karyotype may lead to phenotypic diversification and a risk of reduced sensitivity to hormone therapy.

Objective To explore the establishment,implementation,and outcomes of an integrated physician-nurse team-based comprehensive management model for breast cancer chemotherapy outpatients,ai-ming to provide a reference for standardized patient care.Methods In January 2019,the Breast Surgery De-partment of Peking Union Medical College Hospital developed an integrated physician-nurse team and estab-lished a full-cycle management pathway covering the pre-chemotherapy,chemotherapy,and inter-cycle phases.This model featured appointment-based scheduling,time-segmented visits,and closed-loop patient management.Key performance indicators-including healthcare efficiency,chemotherapy safety,staffing ratios,and satisfaction levels among patients and healthcare providers-were compared between pre-implementation(2018)and post-imple-mentation(2019)periods.Results Before implementation,patient waited times ranged from 30 to 120(75.40±20.97)minutes,with an annual chemotherapy volume of 8 715 cases.Two ward nurses were routinely redeployed daily to support the chemotherapy clinic.Post-implementation,patients received timely chemotherapy per scheduled appointments without delays,annual chemotherapy volume in-creased to 10 101 cases,and staffing between two chemotherapy units became flexibly adjustable.Ward nurses transitioned from an on-call to a reserve role.Adverse events(chemotherapy-related,catheter-related,and nursing incidents)remained at 0,consistent with pre-implementation levels.Both patient and staff satisfaction scores significantly improved across all domains(all P＜0.05).Conclusions The integrated physician-nurse team-based chemotherapy management model enhances service efficiency,ensures treatment safety,optimizes workforce allocation,and improves satisfaction among patients and healthcare providers.

ObjectiveTo evaluate the quality of Lygodium japonicum (Thunb.) Sw. (L. japonicum, Hai Jin Sha) by comparing its components without stewed (W) and stewed (S) using ultra-high-performance liquid chromatography (UHPLC) and chemometric analysis. Additionally, network pharmacology was employed to investigate the possible mechanisms of action of L. japonicum in the urinary calculi (UC) treatment.MethodsA fingerprinting method was established to identify components through UHPLC-tandem mass spectrometry. Chemometric techniques were used to compare the L. japonicum extraction methods. Furthermore, various network pharmacological approaches were used to identify and analyze the potential targets of the identified components in relation to UC.ResultsThe W and S extracts were distributed into two distinct clusters. Significant differences in the levels of protocatechuic aldehyde, caffeic acid, and p-coumaric acid were observed between S and W. Network pharmacology analysis revealed that the primary targets of L. japonicum in the UC treatment were serum albumin and epidermal growth factor receptors, with potential active components including protocatechuic acid and caffeic acid.ConclusionThis study comprehensively examined the therapeutic components of L. japonicum before and after boiling, shedding light on its potential mechanisms of action in UC treatment. These findings offer valuable insights into the development and utilization of L. japonicum resources.
