Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous disease. Although standard first-line regimens can cure >50% of patients, approximately one-third of them develop relapsed/refractory DLBCL (r/r DLBCL). Consequently, immunotherapy targeting molecular abnormalities has become pivotal for managing r/r DLBCL. The results of this review show that with advances in understanding DLBCL pathogenesis and the tumor immune microenvironment, antibody-based therapies have evolved rapidly, progressing from monoclonal antibodies (e.g., rituximab, tafasitamab) to bispecific antibodies(e.g., odronextamab,glofitamab, epcoritamab) and antibody-drug conjugate (e.g., polatuzumab vedotin, loncastuximab tesirine). These engineered agents enhance immune cytotoxicity and tumor-specific targeting, providing novel therapeutic options for r/r DLBCL patients.

ObjectiveTo explore the effects of the Tibetan medicine Sanwei Doukoutang (SWDK) on cognitive dysfunction in mice suffering from Alzheimer's disease (AD) and its related mechanism. MethodsFifty SPF 5 × FAD mice were randomly divided into model group, total ginsenoside group(0.04 g·kg-1), high-, medium-, and low-dose groups of SWDK (32.60, 16.30, 8.15 g·kg-1), with 10 mice in each group, and ten wild-type mice of the same age were used as the normal group, male and female in 1∶1. Gavage administration was performed once daily for 8 weeks. The Morris water maze test and contextual fear memory experiment were used to observe learning and memory function. Hematoxylin-eosin (HE) staining was utilized to observe the changes in the pathomorphology of brain tissue in mice. The levels of synaptophysin (SYP) and postsynaptic dense substance 95 (PSD95) in mice serum were detected by enzyme-linked immunosorbent assay (ELISA). The positive expression of brain-derived neurotrophic factor(BDNF) in the dentate gyrus (DG) region of mouse brain tissue was observed by immunohistochemistry (IHC). The protein levels of BDNF, Wnt family member 3A(Wnt3a), and β-catenin were detected in the hippocampus of mice by Western blot. ResultsCompared with the normal group of mice, the model group of mice had significantly more complex swimming routes and lower swimming speed (P<0.01), significantly lower percentage of time spent in the target quadrant (P<0.01), and a significantly lower percentage of freezing time (P<0.05). The number of neurons in the hippocampal region of mice was obviously reduced and unevenly arranged. The levels of SYP and PSD95(P<0.01) in the serum of mice were reduced, and the positive expression of BDNF in the DG region of the brain tissue of mice was reduced. The levels of hippocampal BDNF, Wnt3a, and β-catenin proteins in the hippocampus of mice were obviously reduced (P<0.05, P<0.01). Compared with the model group, the mice in the SWDK group and the total ginsenoside group had significantly shorter swimming routes, the high- and medium- dose SWDK groups significantly higher swimming speeds (P<0.01), significantly higher percentage of time spent in the target quadrant (P<0.01), obviously higher percentage of Freezing time (P<0.05), and obviously more neurons in the hippocampal region of the mice with tighter arrangement. The mice had elevated levels of serum SYP (P<0.05, P<0.01), PSD95 (P<0.01), increased BDNF-positive cells in the DG region of brain tissue, and obviously elevated levels of BDNF, Wnt3a, and β-catenin proteins in the hippocampus of mice (P<0.05, P<0.01). ConclusionSWDK can significantly improve the cognitive dysfunction of AD mice, and its mechanism may be related to regulating the Wnt/β-catenin signaling pathway, which promotes BDNF expression and thereby enhances synaptic plasticity, allowing neuronal signaling to be restored.

ObjectiveTo investigate the role and mechanism of DNA repair regulation in the process of hepatocellular carcinoma (HCC) recurrence. MethodsHCC tissue samples were collected from the patients with recurrence within two years or the patients with a good prognosis after 5 years, and the Tandem Mass Tag-labeled quantification proteomic study was used to analyze the differentially expressed proteins enriched in the four pathways of DNA replication, mismatch repair, base excision repair, and nucleotide excision repair, and the regulatory pathways and targets that play a key role in the process of HCC recurrence were analyzed to predict the possible regulatory mechanisms. The independent samples t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsFor the eukaryotic replication complex pathway, there were significant reductions in the protein expression levels of MCM2 (P=0.018), MCM3 (P=0.047), MCM4 (P=0.014), MCM5 (P=0.008), MCM6 (P=0.006), MCM7 (P=0.007), PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the nucleotide excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the base excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019) and LIG1 (P=0.042) in the HCC recurrence group; for the mismatch repair pathway, there were significant reductions in the protein expression levels of MSH2 (P=0.026), MSH6 (P=0.006), RFC4 (P=0.002), RFC5 (P<0.001), PCNA (P=0.019), and LIG1 (P=0.042) in recurrent HCC tissue. The differentially expressed proteins were involved in the important components of MCM complex, DNA polymerase complex, ligase LIG1, long patch base shear repair complex (long patch BER), and DNA mismatch repair protein complex. The clinical sample validation analysis of important differentially expressed proteins regulated by DNA repair showed that except for MCM6 with a trend of reduction, the recurrence group also had significant reductions in the relative protein expression levels of MCM5 (P=0.008), MCM7 (P=0.007), RCF4 (P=0.002), RCF5 (P<0.001), and MSH6 (P=0.006). ConclusionThere are significant reductions or deletions of multiple complex protein components in the process of DNA repair during HCC recurrence.

Objective:To explore the long-term therapeutic efficacy and outcomes of liver transplantation for patients with hepatic myelopathy (HM).Methods:Retrospective analysis of 24 adult liver transplantation recipients due to HM at First Central Municipal Hospital from January 2006 to October 2022. HM was extensively classified by the severity of lower extremity symptoms, degree of muscle stiffness, capability for independent ambulation and muscle strength. Furthermore, their long-term outcomes were examined. From January 2000 to October 2022, the databases of China National Knowledge Infrastructure (CNKI) , Google Scholar, PubMed and Web of Science were searched with such keywords as "肝性脊髓病and肝移植" "Hepatic Myelopathy and Liver Transplantation" .Results:After liver transplantation, liver functions and blood ammonia normalized and most clinical symptoms improved. During a follow-up period of (12-190) months, 19 patients showed a lowered grade of HC as compared to pre-transplantation. Four cases achieved a complete recovery of extremity function. No change occurred in severity grade for the remaining 5 patients. However, 4 of them experienced varying degrees of improvement in muscle strength and independent walking capability. This review summarized the clinical characteristics and clinical outcomes of 17 patients from both domestic and international sources. Most of them experiences varying degrees of symptomatic improvements after liver transplantation (16 cases).Conclusions:This study has confirmed the effectiveness of liver transplantation for HM and its contribution to the long-term patient recovery.

OBJECTIVE To establish a research indicator evaluation system suitable for pharmaceutical personnel in children’s hospitals, and provide technical support and reference basis for the evaluation of scientific research capabilities of pharmacy personnel. METHODS The literature/text research methods were adopted to search related literature, policies, regulations and research reports of scientific research management; brainstorming method was used to sort out the key elements and decompose the indicators at all levels step by step. On this basis, using the method of expert interview, the key elements were clarified, the three- level index evaluation system was preliminarily drawn up, and the letter inquiry paper was made accordingly. Finally, Delphi method was used to establish the evaluation system of scientific research indicators for pharmacists through three screening criteria [importance assignment>3.5, coefficient of variation<25%, and unimportant percentage (including unimportant and very unimportant)<50%]. RESULTS Overall 36 questionnaires were distributed by two rounds of expert letters, and 36 questionnaires were recovered, with a recovery rate and an effective rate of 100% for both rounds. The average expert judgment coefficient was 0.912, the average expert familiarity level was 0.747, and the average expert authority coefficient was 0.830. After the second round of letters and inquiries, the values of Kendall’s W of the first-level, the second-level and the third-level indicators were 0.269, 0.379 and 0.460, which were significantly higher than the results of the first round of inquiry (P<0.01). Finally, the evaluation system of scientific research indicators for pharmacists was determined with 4 first-level indicators, 18 second-level indicators and 62 third-level indicators. CONCLUSIONS The pharmaceutical experts from the children’s hospital selected in this study have high authority and wide professional coverage; the evaluation system of scientific research indicators for pharmacists has certain standards and norms, which can provide a powerful reference for the professional level assessment and scientific research ability evaluation of pharmacists.

ObjectiveBidirectional and two-sample Mendelian randomization(MR) method was used to investigate the bidirectional causal relationship between constipation and pneumonia and to understand the potential relationship between the two diseases from a new perspective, providing new targets for future treatment strategies. MethodConstipation and pneumonia datasets were selected from the genome-wide association study(GWAS) website for the European population in 2021. The data related to constipation included 411 623 samples, and the single nucleotide polymorphism(SNP) data were 24 176 599. The pneumonia data contained 480 299 samples with a number of SNPs of 24 174 646. In this study, inverse variance weighting(IVW) was adopted as the main analysis method of MR, supplemented by weighted median method, simple model, weighted model and MR-Egger regression analysis results, and sensitivity analysis was performed to evaluate the robustness of the results. ResultSeventeen SNPs highly correlated with constipation and 12 SNPs highly correlated with pneumonia were finally included. IVW analysis results of forward MR analysis showed that constipation increased the risk of pneumonia{odds ratio(OR)=1.143, 95% confidence interval(CI)[1.045, 1.249], P=0.003}, MR-Egger regression, simple model, weighted model and weighted median analysis all supported the result(P<0.05). IVW analysis by reverse MR analysis showed that pneumonia did not increase the risk of constipation{OR=1.138, 95%CI[0.974, 1.329], P=0.103}, MR-Egger regression, simple model, weighted model and weighted median analysis also supported this result. ConclusionThe bidirectional and dual-sample MR analysis method is used to confirm the causal relationship between constipation and pneumonia from the perspective of genetic variation, while there is no obvious causal relationship on the contrary. This study will be helpful for the clinical diagnosis and treatment of constipation and pneumonia, and provide a reference for the study of the pathogenesis between the two.

Shufeng Jiedu capsules, a Chinese patent medicine composed of Polygoni Cuspidati Rhizoma et Radix, Forsythiae Fructus, etc., has shown positive effects in the clinical treatment of upper respiratory tract infections, pharyngitis, acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and coronavirus disease 2019 (COVID-19). The available evidence suggests that Shufeng Jiedu capsules can modulate the proportions of immune cells and the concentrations of inflammatory cytokines, thereby easing symptoms and enhancing cure rates. The existing reviews predominantly focus on the clinical applications of Shufeng Jiedu capsules, while the comprehensive review of the immunomodulatory effect of this medicine remains to be carried out. This review delineates the immune responses triggered by respiratory tract infections, and then summarizes the clinical application of Shufeng Jiedu capsules and its main chemical components. Principally, this review summarizes the immunomodulatory and anti-inflammatory mechanisms, mainly focusing on various immune cells including macrophages, neutrophils, natural killer (NK) cells, and lymphocytes. In addition, this paper discusses the influences of Shufeng Jiedu capsules and its main chemical components on signaling pathways, secretion of pro-inflammatory cytokines, and antibody production. In terms of innate immunity, the intervention effects of Shufeng Jiedu capsules are highlighted by its capacity to inhibit the activation of nuclear factor kappa-B (NF-κB) and interferon regulatory factor 3 (IRF3) pathways. Additionally, Shufeng Jiedu capsules have been shown to reduce the expression of microtubule-associated protein 1 light chain 3 Ⅱ (LC3Ⅱ), thereby suppressing the inflammation and autophagy of macrophages. Furthermore, the influence of this medicine extends to altering the proportions of neutrophils and nature killer(NK) cells. Regarding adaptive immunity, Shufeng Jiedu capsules can increase the proportion of T cells in peripheral blood and restore the balance of B cells. This review aims to provide directions for the further research and clinical application of Shufeng Jiedu capsules.
