Objective:To identify early predictors of factors influencing the efficacy of infliximab (IFX) treatment in patients with Crohn's disease (CD) .Methods:This study is a nested case-control study, including CD patients treated with IFX at the Second Affiliated Hospital of Soochow University from November 2015 to April 2021 and at the First Affiliated Hospital of Nanjing Medical University from November 2015 to December 2022. All the patients were followed up until June 2023 and categorized into IFX non-response and treatment-effective groups based on changes in clinical symptoms and endoscopic image during the follow-up. Laboratory data of inflammatory markers, post-induction trough IFX concentration and antibody levels in both groups were retrospectively collected and compared. Logistic regression models were employed to identify potential factors associated with the risk of IFX non-responsiveness. Machine learning using random forest analysis was utilized to quantitatively assess the predictive features for IFX treatment efficacy and ROC curves was used to evaluate the model's accuracy.Results:This study included 147 CD patients undergoing IFX treatment, with 58 from the Second Affiliated Hospital of Soochow University and 89 from the First Affiliated Hospital of Nanjing Medical University. Among them, 38 were classified as the IFX non-response group, and 109 as the effective group. Patients in the IFX non-response group had lower trough concentration ( P < 0.001), higher antibody levels ( P < 0.001), and a less pronounced reduction in ESR during the induction therapy ( P < 0.001). Univariate and multi-variate Logistic regression models demonstrated that IFX trough concentration and the ratio of ESR before and after induction therapy was associated with the risk of non-responsiveness. After the induction period, for each unit increase in IFX trough concentration (1 μg/ml), the risk of IFX non-response decreased by 23% ( RR = 0.77, 95% CI = 0.68-0.89), while each doubling of the ESR ratio after induction was associated with a 1.43-fold increase in the risk of non-response ( RR = 2.43, 95% CI = 1.48-4.00). Random forest machine learning analysis revealed that IFX trough concentration below 1.5 μg/ml could predict IFX non-response, with area under the ROC curve was 0.722. Conclusion:Lower post-induction IFX trough concentrations is predictive of IFX non-response, while a lack of significant decrease in ESR during the induction phase is also significantly associated with IFX non-response.

The local microenvironment is essential to stem cell-based therapy for ischemic stroke, and spatiotemporal changes of the microenvironment in the pathological process provide vital clues for understanding the therapeutic mechanisms. However, relevant studies on microenvironmental changes were mainly confined in the acute phase of stroke, and long-term changes remain unclear. This study aimed to investigate the microenvironmental changes in the subacute and chronic phases of ischemic stroke after stem cell transplantation. Herein, induced pluripotent stem cells (iPSCs) and neural stem cells (NSCs) were transplanted into the ischemic brain established by middle cerebral artery occlusion surgery. Positron emission tomography imaging and neurological tests were applied to evaluate the metabolic and neurofunctional alterations of rats transplanted with stem cells. Quantitative proteomics was employed to investigate the protein expression profiles in iPSCs-transplanted brain in the subacute and chronic phases of stroke. Compared with NSCs-transplanted rats, significantly increased glucose metabolism and neurofunctional scores were observed in iPSCs-transplanted rats. Subsequent proteomic data of iPSCs-transplanted rats identified a total of 39 differentially expressed proteins in the subacute and chronic phases, which are involved in various ischemic stroke-related biological processes, including neuronal survival, axonal remodeling, antioxidative stress, and mitochondrial function restoration. Taken together, our study indicated that iPSCs have a positive therapeutic effect in ischemic stroke and emphasized the wide-ranging microenvironmental changes in the subacute and chronic phases.

BACKGROUND: The occurrence and development of lung cancer are closely linked to epigenetic modification. Abnormal DNA methylation in the CpG island region of genes has been found in many cancers. Protein kinase C delta binding protein (PRKCDBP) is a potential tumor suppressor and its epigenetic changes are found in many human malignancies. This study investigated the possibility of PRKCDBP methylation as a potential biomarker for non-small cell lung cancer (NSCLC). METHODS: We measured the methylation levels of PRKCDBP in the three groups of NSCLC tissues. Promoter activity was measured by the dual luciferase assay, with 5'-aza-deoxycytidine to examine the effect of demethylation on the expression level of PRKCDBP. RESULTS: The methylation levels of PRKCDBP in tumor tissues and 3 cm para-tumor were higher than those of distant (>10 cm) non-tumor tissues. Receiver operating characteristic (ROC) curve analysis between tumor tissues and distant non-tumor tissues showed that the area under the line (AUC) was 0.717. Dual luciferase experiment confirmed that the promoter region was able to promote gene expression. Meanwhile, in vitro methylation of the fragment (PRKCDBP_Me) could significantly reduce the promoter activity of the fragment. Demethylation of 5'-aza-deoxycytidine in lung cancer cell lines A549 and H1299 showed a significant up-regulation of PRKCDBP mRNA levels. CONCLUSIONS PRKCDBP methylation is a potential and promising candidate biomarker for non-small cell lung cancer.

Objective:To evaluate the effect of preventing and treatment of pharmaceuticals on intensive care unit-acquired weakness (ICU-AW) by systematic review.Methods:The randomized controlled trials (RCTs) concerning pharmaceutical prevention and treatment about ICU-AW in SinoMed, CNKI, Wanfang data, PubMed, Cochrane Library, Web of Science, EMbase, and other sources were searched from their foundation to May 30th, 2019. The patients in the intervention group were treated with drugs to prevent or treat ICU-AW; and those in control group were treated with other rehabilitation methods. Data searching, extracting and quality evaluation were assessed by two reviewers independently. Stata 12.0 software was then used for Meta-analysis. Only descriptive analysis was conducted when only one study was enrolled.Results:A total of 11 RCTs were enrolled with 1 865 patients in the intervention group and 1 894 in the control group. The results of quality evaluation showed that 4 studies were A-level and 7 studies were B-level, indicating that the overall quality of the enrolled literature was high. Meta-analysis showed that intensive insulin therapy could prevent ICU-AW [relative risk ( RR) = 0.761, 95% confidence interval (95% CI) was 0.662-0.876, P = 0.000], but reduced phenylalanine loss (nmol·100 mL -1·min -1: -3±3 vs. -11±3, P < 0.05) and glutamine intake (nmol·100 mL -1·min -1: -97±22 vs. -51±13, P < 0.05). There was no significant difference in the prevention and treatment of ICU-AW between other drugs (including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin) and control group. Conclusions:Intensive insulin therapy can prevent ICU-AW, but the risk of hypoglycemia will increase. Other drugs including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin have no obvious advantages in the prevention and treatment of ICU-AW, so no drug has been recommended to prevent and treat ICU-AW.
