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.

Transfusion technicians constitute a core workforce in safeguarding blood safety, and the quality of their standardized training directly affects the operational efficiency of the blood services. At present, training programs for transfusion technicians across China have been developed in a diversified manner. Positive progress has been achieved in integrated theoretical and practical training, on-the-job faculty development, and regional collaborative training models. However, persistent challenges remain, including fragmented training providers, inconsistent training standards, limited coverage, and a disconnect between training and workforce utilization. Based on a review of current standardized training practice, this article systematically analyzes the structural challenges confronting current standardized training, and further proposes a framework for building a comprehensive training system, covering the definition and core components of standardized training, targeted improvement strategies and key assessment indicators. The study aims to facilitate the transformation of training for blood transfusion technicians in blood services from a project-based approach to an institutionalized model, and from fragmented implementation to a systematic framework.

Objective: To investigate the incidence and independent risk factors of adverse events (AEs) associated with therapeutic plasma exchange (TPE) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to provide evidence to support the safe use of TPE in clinical practice. Methods: This retrospective study included 167 allo-HSCT recipients who underwent a total of 385 TPE procedures between March 2022 and December 2023. Patients were divided into two groups according to the occurrence of TPE-related AEs. Baseline characteristics, plasma exchange parameters, and clinical features were collected. Univariate analysis and multivariable Firth logistic regression were performed to identify independent risk factors for AEs. Results: A total of 385 TPE procedures were performed in 167 allo-HSCT patients, and 33 patients (19.8%) experienced TPE-related AEs. Among the 33 patients who experienced AEs, allergic reactions were the most common (n=18, 54.5%), followed by blood pressure fluctuations (n=11, 33.3%) and hypocalcemia (n=4, 12.1%). Most AEs were classified as grade II (n=23, 69.7%), and no grade IV (fatal) events were observed. Univariate analysis demonstrated a significant difference in the incidence of AEs among different hematocrit (HCT) categories (<20%, 20%-30%, and>30%) (Fisher's exact test, P=0.022). Although the overall difference was statistically significant, none of the pairwise comparisons remained significant after Bonferroni correction (adjusted P>0.0167). Multivariable Firth logistic regression identified higher HCT levels, analyzed as a continuous variable (OR=1.07, 95% CI: 1.01-1.13, P=0.020), and TPE performed for cytokine release syndrome (CRS) (OR=9.21, 95% CI: 1.25-78.00, P=0.030) as potential independent risk factors for TPE-related AEs. Receiver operating characteristic (ROC) curve analysis showed that HCT had an AUC of 0.67 (95% CI: 0.57-0.77) for predicting AEs, with an optimal cutoff value of 24.5%, a sensitivity of 60.6%, and a specificity of 75.4%. Using this cutoff, the AEs rate was significantly higher in patients with HCT≥24.5% than in those with HCT<24.5% (37.7% vs 11.4%, P<0.001). Conclusion: A-mong allo-HSCT patients receiving TPE, allergic reactions were the predominant AEs. Higher HCT levels and TPE performed for CRS may be associated with an increased risk of AEs. HCT≥24.5% may help identify patients requiring intensified monitoring, although its discriminatory ability is moderate (AUC=0.67) and it should not be used as a standalone criterion for clinical decision-making. Findings regarding the CRS subgroup require validation in larger cohorts. Optimizing extracorporeal circuit priming and strengthening peri-procedural monitoring may help improve the safety of TPE.

Objective To develop a 3D visualization endoscopic navigation system based on CT portal angiography (CTPA) and explore its clinical value in assisting precise treatment of esophageal and gastric varices (EGV). Methods Patients with EGV needing treatment in the Department of Gastroenterology of Zhongshan Hospital, Fudan University from September 2021 to April 2023 were collected. Preoperative examinations including CTPA and hematological examinations were performed, and a 3D visualization endoscopic navigation system was developed to assist endoscopic treatment. Real time comparison was made between the endoscopic 3D portal vein system image reconstructed by intelligent imaging and the actual endoscopic observation of the vascular morphology inside the cavity. The responsible blood vessels that are prone to bleeding were embolized using a sandwich injection method of “lauromacrogol+tissue adhesive+lauromacrogol”. For patients with portal shunting, ultrasound-guided coil insertion was performed. Postoperative endoscopic ultrasound or CTPA was used reexamination to evaluate vascular embolism and complications. Results A total of 13 patients successfully underwent endoscopic ultrasound-guided variceal embolization. The average maximum inner diameter of target veins was (3.3\begin{document}$ \pm $\end{document}1.3) cm; on average, implanted coil number was 1(0,2) in each patient, with median dosages of lauromacrogol and tissue adhesive were 9.5(7.8,10.0) mL and 1.5(1.0,2.1) mL respectively. Postoperatively, endoscopic ultrasound detecting confirmed complete occlusion of all target veins. At 8 weeks after treatment, none of the patients experienced rebleeding. At 24 weeks after treatment, rebleeding occurred in 3 patients, on postoperative days 107, 126 and 147, respectively. Conclusion The 3D visualization endoscopic navigation system based on CTPA can effectively and safely assist preoperative diagnosis and intraoperative localization of target blood vessels, which is beneficial for the precise treatment of EGV patients.

Conclusion:Kuaijie Ankang Decoction may improve metabolites such as Gamma aminobutyric acid and thiamine through metabolic pathways such as lysine biosynthesis to alleviate inflammatory reactions, thereby exerting therapeutic effects on ulcerative colitis in mice.

Estrogen receptor α36(ERα36),a splice variant of ERα66,is crucial in the pathogenesis,progression,and therapeutic resistance of female estrogen-related tumors(e.g.,breast,cervical,and endometrial cancers)as it uniquely activates non-genomic signaling pathways.This review provides a comprehensive summary of the structural features of ERα36 and its molecular mechanisms in regulating tumor prolif-eration,migration,and drug resistance via membrane-mediated pathways,including phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT)and mitogen-activated protein kinase/extracellular signal-regulated kinase(MAPK/ERK).The interaction between ERα36 and epi-dermal growth factor receptor/human epidermal growth factor receptor2(EGFR/HER2)forms a positive feedback loop that exacerbates ma-lignant transformation.High ERα36 expression is associated with decreased sensitivity to chemotherapy and resistance to tamoxifen.Recent studies have demonstrated that natural compounds and synthetic inhibitors targeting ERα36 can reverse drug resistance and suppress can-cer stem cell activity by blocking non-genomic signaling.This review provides novel insights into overcoming drug resistance and optimizing targeted therapies for female estrogen-related malignancies.

Objective:To analyze the molecular characteristics of prevalent Bordetella pertussis (Bp) isolates in Liaocheng City, Shandong Province in 2024. Methods:From March to August 2024, oropharyngeal swabs were collected from suspected pertussis cases at Liaocheng People′s Hospital in Shandong Province for Bp isolation. A total of 99 Bp isolates were obtained. Whole-genome sequencing was performed on all isolates, followed by Multilocus Sequence Typing (MLST), vaccine antigen-related gene typing (including ptxP, ptxA, ptxB, ptxC, ptxD, ptxE, fhaB, fim2, fim3, and prn), 23S rRNA gene typing, and phylogenetic analysis. To capture the differences between Bp isolates and vaccine strains in Liaocheng City, the international vaccine strain Tohama I and the Chinese vaccine strain CS were included in the analysis. Antimicrobial resistance testing against 11 agents was performed on 52 isolates. Results:The throat swabs of 99 Bp isolates were collected from patients aged 44 days to 42 years, and the median age of the patients was 7 (5, 8) years. All isolates ptxP were ptxP3 type. 74 isolates (74.75%) carried the prn150, while 21 isolates (21.21%) were prn-deficient. The predominant antigenic profile was ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150, found in 72 isolates (72.73%). All 99 isolates carried the A2047G mutation in the 23S rRNA gene. Antimicrobial susceptibility testing showed that the MICs of macrolides and clindamycin for all 52 Bp isolates were all >256 mg/L. However, the isolates showed low MIC for seven other antimicrobials tested, including trimethoprim-sulfamethoxazole, amoxicillin, and levofloxacin. MLST typing revealed that 94 isolates (94.95%) were identified as ST-2, while 5 isolates (5.05%) belonged to a novel sequence type (ST-118). Phylogenetic analysis demonstrated that all 99 Bp isolates were highly homologous but clustered in evolutionary branches distinct from vaccine strains. Conclusion:In 2024, Bordetella pertussis isolates in Liaocheng City exhibit distinct clonal epidemic characteristics, with the predominant antigenic genotype being ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150. All isolates are resistant to macrolide antibiotics.

Objective:To evaluate the long-term protective efficacy of the recombinant Chinese hamster ovary cell-derived hepatitis B vaccine（CHO-HepB）26 years post-vaccination in the rural China.Methods:Zhengding county，Hebei province was designated as a rural monitoring site for CHO-HepB efficacy. Study participants included individuals born between 1997 and 1999 who had completed the three-dose CHO-HepB primary series without booster doses. A cross-sectional survey was conducted in late 2024 using random sampling. Demographic and vaccination history data were collected via questionnaires，and hepatitis B virus（HBV）serological markers were detected using chemiluminescence. Historical surveillance data were integrated to infer infection statuses of HBsAg-positive individuals and evaluate longitudinal trends in anti-HBs seropositivity and antibody titers.Results:Among 178 participants（mean time since vaccination：26.2 years），the seroprevalence rates were 0.6% for HBsAg（95% CI：0.0%-1.6%），64.6% for anti-HBs（95% CI：57.6%-71.6%），and 1.1% for anti-HBc（95% CI：0.0%-2.7%）. Compared to the pre-vaccination baseline HBsAg positivity of 11.3% in children under 10 years of age，the estimated vaccine protection rate was 95%. Two notable cases were identified：one with concurrent HBsAg and anti-HBc positivity and one with anti-HBs and anti-HBc positivity，suggestive of transient HBV exposure（1999—2009）without chronicity. Natural immune boosting was inferred for the latter case based on anti-HBs titer dynamics. Longitudinal analysis of four prior cross-sectional surveys（2005，2009，2013，and 2017）revealed no significant upward trends in HBsAg and anti-HBc positivity（both P>0.05）over 26 years，while anti-HBs seropositivity declined significantly（ P<0.05）from 6 to 26 years post-vaccination. Conclusion:The CHO-HepB vaccine demonstrates sustained immunological persistence and robust long-term protection up to 26 years post-immunization. Continued emphasis on rigorous implementation of mother-to-child transmission prevention strategies is critical for future hepatitis B control.
