Most patients with pancreatic cancer are already in the locally advanced or metastatic stage at initial diagnosis. While systemic chemotherapy provides clinical benefits for those with mid-to-late-stage pancreatic cancer, its efficacy is often limited by patient tolerance. In response to the dual clinical demands of robust antitumor activity and high targeting specificity, antibody-drug conjugate (ADC) has emerged as a promising solution. By conjugating highly selective monoclonal antibodies with potent cytotoxic small-molecule drugs, ADC achieves precise tumor-targeting while minimizing damage to healthy tissues, which thereby improves treatment tolerance. However, due to the complex pathological features of pancreatic cancer, no ADC has yet been approved for clinical use for this disease. A comprehensive evaluation of factors including ADC-specific targets, payload selection, antibody-drug linkage strategies, drug delivery mechanisms, tissue distribution variability, and tumor heterogeneity will be crucial to advancing the clinical translation of ADC for pancreatic cancer treatment.

Objective:To systematically review the current registered clinical study schemes in China regarding the combination of TCM and targeted drug therapy for lung cancer; To analyze their strengths and weaknesses; To provide reference for future study.Methods:Chinese Clinical Trial Registry for clinical study schemes combining TCM with targeted drug therapy for lung cancer treatment was retrieved from the inception to July 10, 2024. The general characteristics, study types, intervention measures, and outcome indicators of existing schemes were systematically summarized and analyzed.Results:A total of 15 studies were included, with the earliest study registered in 2013. Registration locations were concentrated in Shanghai, Guangdong, Tianjin, and Zhejiang. Among them, 9 studies received funding from local, national finance, or hospitals; 13 studies passed ethical review, and 12 included informed consent. The design schemes included 10 randomized controlled studies, 1 cohort study, 1 interventional single-arm study, and 3 observational studies. 6 studies had a sample size smaller than 100 cases, and most were single-center trials. Intervention measures primarily involved the combination of Chinese patent medicine or TCM with targeted drugs, with evaluation indicators mainly focusing on clinical symptoms and laboratory indicators. The setting of outcome indicators lacked a unified standard.Conclusions:Since 2013, clinical studies combining TCM with targeted drug therapy for lung cancer have been relatively methodologically sound but face challenges such as small sample sizes and a certain degree of regional concentration, leading to relatively insufficient representativeness. The future direction for improvement lies in multi-center, large-sample, and well-designed clinical trials. It is also necessary to establish a standardized and normalized system for evaluating outcomes. Integrating basic research to clarify the mechanisms of TCM can provide a theoretical basis for the combination of TCM and targeted drugs, which is conducive to enhancing the rigor and scientific nature of clinical trial design and promoting the formation of high-level evidence-based medicine.

A 55-year-old male patient was treated with tacrolimus (2.5 mg in the morning and 2 mg at night) for 6 months after lung transplantation to prevent rejection. The blood trough concentration of tacrolimus was stable at 8.0-10.0 μg/L. The patient received antiviral treatment due to corona virus disease 2019 (nirmatrelvir/ritonavir 300 mg/100 mg twice daily orally for a total of 5 days). During the antiviral treatment, the patient continued the anti-rejection treatment. On the second day of antiviral treatment, the patient′s blood trough concentration of tacrolimus increased to >40.0 μg/L, which was considered to be caused by the interaction between nirmatrelvir/ritonavir and tacrolimus. Tacrolimus was withdrawn and antiviral therapy was continued. After discontinuation of tacrolimus for 8 days and nirmatrelvir/ritonavir for 3 days, the blood trough concentration of tacrolimus decreased to 25.7 μg/L. After re-giving tacrolimus at reducing dosage for 3 days, the blood trough concentration of tacrolimus was 8.3 μg/L. After 13 days of resuming administration of tacrolimus at the original dose and frequency, the patient′s blood trough concentration of tacrolimus was 9.2 μg/L. Since then, the blood trough concentration of tacrolimus in the patient was not abnormal again.

BACKGROUND:
Islet transplantation is currently considered the most promising method for treating insulin-dependent diabetes. The two most-studied artificial islets are alginate-encapsulated b cells or b cell spheroids. As three-dimensional (3D) models, both artificial islets have better insulin secretory functions and transplantation efficiencies than cells in twodimensional (2D) monolayer culture. However, the effects of these two methods have not been compared yet. Therefore, in this study, cells from the mouse islet b cell line Min6 were constructed as scaffold-free spheroids or alginate-encapsulated dispersed cells.
METHODS:
MIN6 cell spheroids were prepared by using Agarose-base microwell arrays. The insulin secretion level was determined by mouse insulin ELISA kit, and the gene and protein expression status of the MIN6 were performed by Quantitative polymerase chain reaction and immunoblot, respectively.
RESULTS:
Both 3D cultures effectively promoted the proliferation and glucose-stimulated insulin release (GSIS) of MIN6 cells compared to 2D adherent cells. Furthermore, 1% alginate-encapsulated MIN6 cells demonstrated more significant effects than the spheroids. In general, three pancreatic genes were expressed at higher levels in response to the 3D culture than to the 2D culture, and pancreatic/duodenal homeobox-1 (PDX1) expression was higher in the cells encapsulated in 1% alginate than that in the spheroids. A western blot analysis showed that 1% alginate-encapsulated MIN6 cells activated the phosphoinositide 3-kinase (PI3K)/serine/threonine protein kinase (AKT)/forkhead transcription factor FKHR (FoxO1) pathway more than the spheroids, 0.5% alginate-, or 2% alginate-encapsulated cells did. The 3D MIN6 culture, therefore, showed improved effects compared to the 2D culture, and the 1% alginate-encapsulated MIN6 cells exhibited better effects than the spheroids. The upregulation of PDX1 expression through the activation of the PI3K/AKT/FoxO1 pathway may mediate the improved cell proliferation and GSIS in 1% alginate-encapsulated MIN6 cells.
CONCLUSION
This study may contribute to the construction of in vitro culture systems for pancreatic islets to meet clinical requirements.

Objective:To investigate the relationship between red blood cell distribution width (RDW) and activity of Crohn′s disease (CD), and explore the diagnostic value of RDW for CD activity.Methods:A cross-sectional study was conducted. Clinical data of CD patients treated continuously at the Sixth Affiliated Hospital of Sun Yat-sen University from November 2012 to October 2014 (CD group) were collected, including the first results of routine hematological examinations and C-reactive protein (CRP) levels after admission. Routine hematological examination results were also collected from healthy peoples undergoing regular health check-ups at the same time, who served as the normal control group. CD patients were divided into remission, mild activity, and moderate-severe activity groups based on the Crohn′s disease activity index (CDAI). The levels of routine hematological indicators including RDW and platelet-to-lymphocyte ratio (PLR) were compared between the CD group and the normal control group, as well as among different subgroups of CD patients. The correlations between RDW, PLR and CD activity or CRP were analyzed, and the diagnostic value of RDW for CD activity was evaluated by using ROC curve. Logistic univariate and multivariate regressions were performed to analyze the influencing factors of the activity of CD. Logistic regression equation was constructed to calculate the diagnostic efficacy of the influencing factors.Results:A total of 303 CD patients (216 males, 87 females; mean age 28.6 ± 11.7 years) were assigned to CD group and 293 healthy peoples (190 males, 103 females; mean age 30.1 ± 12.3 years) were assigned to normal control group. There was no significant differences in age and gender between the two groups (both P>0.05), indicating comparability. Among the CD patients, 109 were in remission group, 106 in mild activity group, and 88 in moderate-severe activity group. There was no significant differences in age and gender among the three subgroups (all P>0.05), indicating comparability. Compared with the normal control group, RDW (15.26% ± 2.51% vs. 13.10% ± 1.13%, P<0.001), PLR (245.09 ± 158.69 vs. 119.07 ± 36.52, P<0.001), neutrophil-to-lymphocyte ratio (NLR) [3.22 (2.06, 4.75) vs. 1.76 (1.39, 2.32), P<0.001], white blood cell count [ (7.68 ± 3.30) ×10 9/L vs. (6.52 ± 1.68) × 10 9/L, P<0.001] and platelet count [ (320.69 ± 116.10) × 10 12/L vs. (230.10 ± 51.08) × 10 12/L, P<0.001] were significantly higher in the CD group, while hemoglobin [ (112.8 ± 21.0) g/L vs. (137.1 ± 13.5) g/L, P<0.001] and platelet distribution width (PDW) [ (10.70 ± 1.91) fl vs. (11.89 ± 1.75) fl, P<0.001] were significantly lower. Compared with patients in remission group, the patients in mild activity group had higher RDW and platelet count, and lower hemoglobin (all P<0.05). Compared with the patients in remission and mild activity groups, the patients in moderate-severe activity group had higher RDW, PLR and NLR, and lower hemoglobin (all P<0.05). Correlation analysis showed the positive correlations between RDW, PLR and CD activity ( r = 0.423, P<0.001; r = 0.295, P<0.001), and RDW was positively correlated with CRP ( r = 0.438, P<0.001). The cut-off value of RDW for predicting CD activity was 13.85%, while the area under curve (AUC) was 0.723 (95% CI: 0.664-0.782, P<0.001), sensitivity was 0.784 and specificity was 0.550. Logistic multivariable regression analysis showed that RDW ( OR = 1.532, 95% CI: 1.291-1.818, P<0.001) and PLR ( OR = 1.003, 95% CI: 1.001-1.006, P = 0.013) were independent risk factors. The combination of RDW and PLR in diagnosing CD activity yielded an AUC of 0.730 (95% CI: 0.673-0.787, P<0.001), sensitivity of 0.407, and specificity of 0.927. Conclusions:CD patients with high RDW have more severe activity. RDW is a simple and practical indicator for diagnosing the activity of CD.
