This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Objective: To study the impact of disaggregation on the quality of in vitro aggregated apheresis platelets. Methods: The apheresis platelets collected from Guangzhou Blood Center served as the study samples. The in vitro aggregated apheresis platelets after successful disaggregation were designated as the experimental group (referred to as the aggregation group), and apheresis platelets without in vitro aggregation during collection served as the control group. The product volume, platelet content, residual white blood cells, red blood cell contamination, pH value, CD62p expression rate, platelet morphology score and thromboelastography of both groups were respectively detected. Results: The routine quality control indicators such as product volume, platelet content, residual white blood cells, red blood cell contamination, and pH value of both groups all met the quality requirements. There were statistically significant differences in pH value (7.180 vs 7.071) between the two groups (P<0.05). There was no significant difference in product volume, platelet content, residual white blood cells, and red blood cell contamination between the two groups (P>0.05). The CD62p expression rate of the aggregation group was higher than that of the control group (42.386% vs 17.310%, P<0.05), while the cell morphology score of the aggregation group was lower than that of the control group (132.066 vs 141.166, P<0.05). No statistically significant differences were found in thromboelastography parameters (R-CK, K-CK, α angle, MA-CK, CI-CK) between the two groups (P>0.05). Conclusion: After the disaggregation of in vitro-aggregated apheresis platelets, the quality indicators met the national quality requirements. Although the expression rate of CD62p increased and the cell morphology score decreased, there were no statistically significant differences in the thromboelastography parameters between the two groups. This indicates that although some platelet activation occurred, it did not affect the hemostatic function of the platelets.

Objective To investigate the clinical efficacy of Xiaoluo Granules combined with an-tituberculosis drugs in the treatment of patients with cervical lymph node tuberculosis.Methods A retrospective analysis was conducted on the clinical data of 118 patients with cervical lymph node tu-berculosis who were treated in our hospital from January 2021 to January 2023.The patients were di-vided into control group(57 patients receiving conventional antituberculosis drug treatment)and ob-servation group(61 patients receiving Xiaoluo Granules combined with antituberculosis drug treat-ment)based on their treatment methods.The efficacy,traditional Chinese medicine(TCM)symptom scores,peripheral blood T-cell subsets,and type 1/type 2 helper T cell(Th1/Th2)-related cytokine levels,including tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-10(IL-10),and interferon-γ(IFN-γ),were compared between the two groups.Results After 6 months of treat-ment,the total effective rate in the observation group was higher than that in the control group(P＜0.05).After 6 months of treatment,the scores for pain,low fever,fatigue,anorexia,and night sweats decreased in both groups,and the scores for these symptoms in the observation group were lower than those in the control group(P＜0.05).After 6 months of treatment,CD3+,CD4+,and CD4+/CD8+increased,while CD8+decreased in both groups.Additionally,CD3+,CD4+,and CD4+/CD8+were higher,while CD8+was lower in the observation group than those in the control group(P＜0.05).After 6 months of treatment,TNF-α,IL-6,and IFN-γ levels decreased,while IL-10 levels increased in both groups.Furthermore,TNF-α,IL-6,and IFN-γ levels were lower in the observa-tion group than in the control group,while IL-10 levels were higher(P＜0.05).Conclusion Xia-oluo Granules combined with antituberculosis drugs can significantly improve the efficacy in the treatment of cervical lymph node tuberculosis and enhance immune function by upregulating CD3+,CD4+,CD4+/CD8+,and IL-10 levels and downregulating CD8+,TNF-α,IL-6,and IFN-γ levels.

Background and purpose:The aberrant activation of pyruvate dehydrogenase kinase 1(PDK1)drives tumor microenvironment remodeling and metastasis through mediating the Warburg effect.As a critical tumor-suppressive phosphatase,phosphatase and tensin homolog deleted on chromoseme ten(PTEN)activates PDK1 via loss of expression to induce aerobic glycolysis and accelerate tumor progression.The molecular interplay between PDK1 and PTEN in kidney renal clear cell carcinoma(KIRC)urgently requires systematic elucidation.This study aimed to clarify how PTEN regulates PDK1 to inhibit malignant phenotypes in KIRC.Methods:Bioinformatics analysis was conducted to compare PTEN and PDK1 expression levels as well as their prognostic correlations in the Cancer Genome Atlas(TCGA)-KIRC datasets.KIRC cell models was established by either silencing PDK1 or enhancing its expression,subsequently evaluating their malignancy characteristics through cell counting kit-8(CCK-8)proliferation,colony formation,cell migration,and invasion assays.To validate the regulatory interactions,we used PDK1-overexpressing cells treated with a PTEN-specific inhibitor.Western blot was used to dectect the protein expression.Results:The TCGA-KIRC analysis found significantly higher mRNA levels of PTEN and PDK1 in tumor tissues compared to normal controls(P＜0.05),yet this high expression was associated with improved overall survival(P＜0.01).Besides,a strong positive correlation was observed between PTEN and PDK1 expressions(r=0.52,P＜0.001).Functional assays demonstrated that PDK1 knockdown markedly promoted cell proliferation,migration,and invasion,whereas PDK1 overexpression exhibited opposing effects.Mechanistically,inhibiting PTEN worsened malignant behaviors(P＜0.01),however,these effects were reversed by overexpressing PDK1.Conclusion:This study presents the first evidence of the dual tumor-suppressive function of the PTEN-PDK1 biological axis in renal cancer,which supports the development of precision treatment strategies based on novel targets.

Objective:To compare the clinical efficacy and safety of bronchial artery chemoembolization (BACE) combined with anlotinib (BACE+A) versus BACE alone in patients with stage III-IV non-small cell lung cancer (NSCLC).Methods:A total of 94 patients with advanced NSCLC treated at six interventional centers between November 2020 and November 2021 were retrospectively enrolled. Patients were divided into the BACE+A group ( n=46) and the BACE alone group ( n=48) based on treatment regimen. Baseline and perioperative clinical data were collected and compared between the two groups. Treatment response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 1, 6, and 12 months after the first BACE procedure. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were recorded. Kaplan-Meier survival curves were plotted to compare median OS and PFS between groups. Cox proportional hazards regression analysis was used to identify factors influencing OS and PFS. Results:The Kaplan-Meier analysis showed that the median OS was significantly longer in the BACE+A group (18.8 months, 95% CI 16.3-21.3) than in the BACE group (13.4 months, 95% CI 11.6-15.2) ( P=0.001). The median PFS was also significantly longer in the BACE+A group (9.0 months, 95% CI 7.3-10.7) compared to the BACE group (6.1 months, 95% CI 4.9-7.3) ( P=0.001). At 6 and 12 months post-first BACE, the ORR (43.5%, 40.0%) and DCR (89.1%, 83.3%) were significantly higher in the BACE+A group than in the BACE group (ORR: 20.8%, 14.8%; DCR: 66.7%, 59.3%) (all P<0.05). Multivariate Cox regression identified treatment with BACE+A ( HR=0.42, 95% CI 0.27-0.72, P=0.002), tumor stage ( HR=1.80, 95% CI 1.05-3.07, P=0.031), presence of pre-existing complications requiring intervention ( HR=2.72, 95% CI 1.65-4.50, P<0.001), and >2 BACE procedures ( HR=0.32, 95% CI 0.15-0.68, P=0.003) as independent factors influencing OS. Treatment with BACE+A ( HR=0.49, 95% CI 0.32-0.76, P=0.001), tumor stage ( HR=1.72, 95% CI 1.07-2.77, P=0.025), multi-arterial tumor blood supply ( HR=2.76, 95% CI 1.76-4.31, P<0.001), and>2 BACE procedures ( HR=0.40, 95% CI 0.22-0.71, P=0.002) were independent factors influencing PFS. There was no significant difference in BACE-related adverse events between the two groups (all P>0.05). Hypertension, fatigue, hand-foot syndrome, and anorexia were common anlotinib-specific adverse reactions in the combination group, but no grade 4 or higher adverse reactions were observed. Conclusions:BACE combined with anlotinib demonstrates superior efficacy compared to BACE alone in treating advanced NSCLC, significantly prolonging OS and PFS. The safety profile is manageable, with adverse events remaining within tolerable limits.

Peptide-based hydrogel, the polymer materials with a special network structure, are widely used in various fields of biomedicine due to their stable properties and biocompatibility. Environment-responsive self-assembled peptide aqueous solutions can respond to environment changes by the self-assembly of peptides into nanofiber networks. Peptide-based hydrogels well simulate the extracellular matrix and cell growth microenvironment, being suitable for 3D cell culture and organoid culture. To establish a tumor organoid culture system with peptide-based hydrogels, we cultured Panc-1, U87, and H358 cells in a 3D spherical manner using CulX Ⅱ peptide-based hydrogels in 24-well plates for 15 days. The organoids showed a 3D spherical shape, and their sizes increased with the extension of the culture time, with a final diameter ranging from 150 to 300 μm. The organoids had a large number, varying sizes, good cell viability, clear edges, and a good shape, which indicated successful organoid construction. The tumor organoid culture system established in this study with CulX Ⅱ peptide-based hydrogels provides a model for studying tumor pathogenesis, drug development, and tumor suppression.
