ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

Efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation treatment for T lymphoblastic leukemia/lymphoma / 中华血液学杂志

Objective: To analyze the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for treating T lymphoblastic leukemia/lymphoma (T-ALL/LBL) . Methods: This study retrospectively evaluated 119 adolescent and adult patients with T-ALL/LBL from January 2006 to January 2020 at Peking University Third Hospital and Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences. Patients were divided into chemotherapy-only, chemotherapy followed by allo-HSCT, and chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) groups according to the consolidation regimen, and the 5-year overall survival (OS) and progression-free survival (PFS) rates of each group were compared. Results: Among 113 patients with effective follow-up, 96 (84.9%) patients achieved overall response (ORR), with 79 (69.9%) having complete response (CR) and 17 (15.0%) having partial response (PR), until July 2022. The analysis of the 96 ORR population revealed that patients without transplantation demonstrated poorer outcomes compared with the allo-HSCT group (5-year OS: 11.4% vs 55.6%, P=0.001; 5-year PFS: 8.9% vs 54.2%, P<0.001). No difference was found in 5-year OS and 5-year PFS between the allo-HSCT and auto-HSCT groups (P=0.271, P=0.197). The same results were achieved in the CR population. Allo-HSCT got better 5-year OS (37.5% vs 0) for the 17 PR cases (P=0.064). Different donor sources did not affect 5-year OS, with sibling of 61.1% vs hap-haploidentical of 63.6% vs unrelated donor of 50.0% (P>0.05). No significant difference was found in the treatment response in the early T-cell precursor acute lymphoblastic leukemia/lymphoma (ETP) and non-ETP populations. The ETP group demonstrated lower 5-year OS compared with the non-ETP group in the chemotherapy alone group (0 vs 12.6%, P=0.045), whereas no significant difference was found between the ETP and non-ETP groups in the allo-HSCT group (75.0% vs 62.9%, P=0.852). Multivariate analysis revealed that high serum lactate dehydrogenase level, without transplantation, and no CR after chemotherapy induction were independently associated with inferior outcomes (P<0.05) . Conclusion: Allo-HSCT could be an effective consolidation therapy for adult and adolescent patients with T-ALL/LBL. Different donor sources did not affect survival. Allo-HSCT may overcome the adverse influence of ETP-ALL/LBL on OS.

"Accordion" technique to promote bony union at the docking site in the treatment of tibial bone defects by Ilizarov technique / 中华创伤骨科杂志

Objective:To evaluate the effect of "accordion" technique on promoting bony union at the docking site in the treatment of tibial bone defects by bone transport.Methods:A retrospective study was conducted to analyze the data of 11 patients with tibial bone infection who had been admitted to Department of Orthopedics, The Second Hospital of Shanxi Medical University from November 2017 to February 2019. There were 10 males and 1 female with an age of (47.0±9.7) years. Seven patients were infected after internal/external fixation for open fractures and 4 cases after internal fixation for closed fractures. After surgical debridement, sensitive antibiotic bone cement was implanted, and dead or infected bone segments were radically resected. In all patients, the resulting bone defects of (6.6±2.9) cm were fixated by an Ilizarov ring external fixator and filled by bone transport. The "accordion" technique was used after the bone segments touched the docking site. The closure time, "accordion" time, bony union time and complications during bone transport were recorded.Results:None of the patients underwent bone grafting. This case series was followed up for (2.7±0.5) years. The closure time was (30.8±6.8) weeks, the "accordion" time (43.1±8.4) days, and the bony union time (31.6±9.0) weeks. None of the patients had obvious pain. Ankle stiffness was observed in 3 patients and traumatic equinus deformity in 1 patient.Conclusions:The "accordion" technique based on the Illizarov technique can accelerate mineralization of the bone segments transported, promote the bony union at the docking site, and effectively solve the problem of tibial bone defects without surgical bone grafting.

Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair (version 2023) / 中华创伤杂志

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

Analysis of risk factors for endometrial atypical hyperplasia and endometrial cancer / 中国医师杂志

Objective:To explore the high-risk factors of endometrial cancer (EC) and provide clinical basis for early screening, diagnosis and treatment of EC.Methods:From January 2017 to December 2022, patients admitted to Shanxi Provincial Maternal and Child Health Hospital for hysteroscopic surgery or diagnostic curettage due to abnormal uterine bleeding, postmenopausal vaginal bleeding and other related symptoms were selected as the research objects. After histopathological examination, they were diagnosed with no atypical endometrial hyperplasia (EH), atypical endometrial hyperplasia (AEH), and EC as the research subjects. The general data of patients′ records, vaginal ultrasound, cervical liquid-based cytology test (LCT), carbohydrate antigen 125 (CA125) and pelvic magnetic resonance imaging were collected, and a case-control study was conducted and the risk factors of AEH and EC were explored using univariate and multivariate logistic regression analysis.Results:This study included a total of 420 cases, including 215 in the EH group, 69 in the AEH group, and 136 in the EC group. Through the comparison of various indicators among the three groups and the results of univariate factor logistic regression analysis, age, menopause, previous delivery history, hypertension, diabetes, color ultrasound showed endometrial thickening (>10 mm), uneven endometrial echo, abnormal echo mass in the uterine cavity, endometrial blood flow signals, cervical LCT examination showed that atypical glandular cells were related to the occurrence of EC, with a statistically significant difference (all P<0.05). The results of multivariate logistic regression analysis showed that age>48 years ( OR=3.65, 95% CI: 2.06-6.45), menopause ( OR=3.19, 95% CI: 1.46-6.98), uneven endometrial echo ( OR=4.08, 95% CI: 2.26-7.36), and intrauterine blood flow signal ( OR=2.91, 95% CI: 1.52-5.58), cervical LCT suggests that atypical glandular cells ( OR=4.25, 95% CI: 1.38-13.11) were independent risk factors for EC and precancerous lesions (all P<0.05). Conclusions:For patients with clinical symptoms such as abnormal uterine bleeding or postmenopausal bleeding, timely and focused screening based on whether they have EC risk factors is an economic, safe, and effective method for early detection and treatment of EC.

Taking the Department of Pathology of Duke University as an example, this paper compares and analyzes the training mode of pathology residents in China and the United States. It is found that the organization and management system and supervision and assessment system of residency training in China have been improved, but it is still necessary to strengthen the in-depth implementation of humanistic education and training subjects for residents. Pathologist training should be based on "elite education" as the guiding ideology, to cultivate high-quality, high-level outstanding clinical pathology personnel as the specific goal, to build a solid foundation of clinical medicine.

Overcoming chemoresistance in non-angiogenic colorectal cancer by metformin via inhibiting endothelial apoptosis and vascular immaturity / 药物分析学报

The development of chemoresistance which results in a poor prognosis often renders current treatments for colorectal cancer(CRC).In this study,we identified reduced microvessel density(MVD)and vascular immaturity resulting from endothelial apoptosis as therapeutic targets for overcoming chemoresistance.We focused on the effect of metformin on MVD,vascular maturity,and endothelial apoptosis of CRCs with a non-angiogenic phenotype,and further investigated its effect in overcoming chemoresistance.In situ transplanted cancer models were established to compare MVD,endothelial apoptosis and vascular maturity,and function in tumors from metformin-and vehicle-treated mice.An in vitro co-culture system was used to observe the effects of metformin on tumor cell-induced endothelial apoptosis.Transcriptome sequencing was performed for genetic screening.Non-angiogenic CRC developed inde-pendently of angiogenesis and was characterized by vascular leakage,immaturity,reduced MVD,and non-hypoxia.This phenomenon had also been observed in human CRC.Furthermore,non-angiogenic CRCs showed a worse response to chemotherapeutic drugs in vivo than in vitro.By suppressing endo-thelial apoptosis,metformin sensitized non-angiogenic CRCs to chemo-drugs via elevation of MVD and improvement of vascular maturity.Further results showed that endothelial apoptosis was induced by tumor cells via activation of caspase signaling,which was abrogated by metformin administration.These findings provide pre-clinical evidence for the involvement of endothelial apoptosis and subsequent vascular immaturity in the chemoresistance of non-angiogenic CRC.By suppressing endothelial apoptosis,metformin restores vascular maturity and function and sensitizes CRC to chemotherapeutic drugs via a vascular mechanism.

Bioinformatic analysis of the expression of KIF14 and its clinical significance and biological functions in clear cell renal cell carcinoma / 现代泌尿外科杂志

【Objective】 To investigate the expression of Kinesin family member 14 (KIF14), and its correlation with clinical prognosis and immune cell infiltration of clear cell renal cell carcinoma (ccRCC). 【Methods】 The correlation between KIF14 expression in ccRCC and different clinicopathological features were analyzed with TCGA, GEO and Ualcan databases. The correlation between KIF14 expression and prognosis was analzyed with Kaplan-Meier method. The correlation between KIF14 expression and immune cell infiltration was analzyed with TIMER. The protein-protein interaction network of KIF14 was conducted with Genemania. The co-expression genes of KIF14 in TCGA-KIRC were picked out in Linkedomics database and were used to perform GO annotations and KEGG pathway enrichment analysis with R software. The biological functions of KIF14 were verified with in vitro functional assay. 【Results】 KIF14 was highly expressed in ccRCC tissue and was positively correlated with clinical stage, pathological grade, and lymphatic metastasis, but negatively correlated with clinical prognosis. KIF14 expression was an independent risk factor for overall survival of ccRCC patients. GO annotations showed that KIF14 was involved in DNA replication, nuclear division, organelle fission, and cell adhesion. KEGG pathway enrichment analysis showed that KIF14 participated in cell cycle and p53 signaling pathway. Genemania analysis indicated KIF14 interacted with CENPE, CIT, KIF23, and other proteins. Timer showed that KIF14 was positively correlated with immune cell infiltration. Knockdown of KIF14 expression suppressed cell proliferation, migration, and invasion of ccRCC. 【Conclusions】 KIF14 may serve as a novel prognostic marker and a potential therapeutic target of clear cell renal cell carcinoma.

Mechanism of TRPC in promoting extracellular matrix deposition of glomerular mesangial cells / 西安交通大学学报(医学版)

【Objective】 To explore the role and mechanism of TRPC in promoting extracellular matrix (ECM) deposition in rat glomerular mesangial cells (HBZY-1). Methods Immunofluorescence staining was performed to observe the distribution and expression of TRPC1 and TRPC6 in HBZY-1 cells. After AngⅡ stimulation, qRT-PCR and Western blotting were used to detect the mRNA and protein expressions of Gαq/PLCβ4/TRPC signaling pathway main proteins and ECM deposition indicators (α-SMA, collagenⅢ and fibronectin). By silencing the expressions of TRPC1 and TRPC6 by RNA interference, the expressions of ECM deposition indicators were detected. Changes in [Ca2+]i influx were determined through Fluo-4AM Ca2+ imaging. 【Results】 Both TRPC1 and TRPC6 were expressed in HBZY-1, and were mainly located in cell membrane and cytoplasm. After AngⅡ stimulation, Gαq/PLCβ4/TRPC signaling pathway was activated, and the mRNA and protein expressions of Gαq, PLCβ4, TRPC1 and TRPC6 were all increased (P<0.05). [Ca2+]i influx also increased (P<0.01), and the mRNA and protein expressions of ECM deposition indicators (α-SMA, ColⅢ and Fn) were upregulated (P<0.05). Silencing the expressions of TRPC1 and TRPC6 by RNA interference led to decreased [Ca2+]i influx (P<0.05), and downregulated mRNA and protein expressions of ECM deposition indicators in HBZY-1 cells (P<0.05). The results suggested that inhibition of TRPC expressions could inhibit AngⅡ induced ECM deposition in HBZY-1 cells, which might be associated with decreased [Ca2+]i influx. 【Conclusion】 TRPC may be a novel therapeutic target of renal fibrosis.

Impurity spectra of lansoprazole enteric-coated preparations by high performance liquid chromatography-high resolution orbital trap mass spectrometry / 中国药科大学学报

@#Using high performance liquid chromatography and high resolution orbital trap mass spectrometry, a two-dimensional online desalting detection method was established to determine the structure of the impurities detected under the official testing conditions of lansoprazole enteric solution preparation, and a chromatographic method compatible with mass spectrometry was established to determine and presume the structure of the impurities that could not be separated by the the official testing method.The identification of impurity was to presume its structure according to the presence of impurity reference product, so as to investigate the difference of impurity spectrum of products from different manufacturers.The one-dimensional chromatographic conditions for the 2D online desalting method were the same as those in China Pharmacopoeia (2020) under relevant substances.Two-dimensional chromatography was performed on a Waters C18 T3 column (2.1 mm × 100 mm, 1.7 μm) with 0.1% formic acid in water-acetonitrile mobile phase and gradient elution.The chromatographic conditions for the compatible mass spectra were based on an Agilent Extend C18 (4.6 mm × 150 mm, 5 μm) column with mobile phase A: 25 mmol/L ammonium acetate and B: 25 mmol/L ammonium acetate-acetonitrile (1∶4) [pH adjusted to 6.5 with glacial acetic acid], with gradient elution. Nine impurities were detected by two-dimensional online desalting method, with 5 known impurities (A-E) and 4 unknown ones.14 impurities were detected by the compatible mass spectrometry method, with 9 unknown impurities (4 consistent with the results of two-dimensional online desalting method, and 5 newly detected).The structures and sources of the unknown impurities were deduced.The two detection methods of lansoprazole preparation by high-performance liquid chromatography-high resolution orbital trap mass spectrometry have guiding significance for quality control and process evaluation.

Perceptions of older adults and generativity among older citizens in Japan: a descriptive cross-sectional study

Objectives@#As the population ages worldwide, including in Japan, there is a growing expectation for older adults to remain active participants in society. The act of sharing one’s experiences and knowledge with younger generations through social engagement not onlyenriches the lives of older individuals, but also holds significant value for our society. In thisstudy, we examined both positive and negative perceptions of older adults and investigated the correlation between these perceptions and generativity among older citizens. Additionally, we evaluated the impact of life satisfaction on these factors. @*Methods@#We conducted a survey of 100 older adults in Japan (mean age, 71.68 years) and utilized multiple regression analyses, using positive and negative perceptions of older adults, life satisfaction, and demographic factors as independent variables. The sub-categories of generativity—namely, generative action, concern, and accomplishment—were used as dependent variables. @*Results@#Participants who held a more positive perception of older adults demonstrated a higher level of generative actions and concerns. Additionally, participants who reported higher levels of life satisfaction also exhibited more generative actions, concerns, and accomplishments. Conversely, those who held a more negative perception of older adults were found to have higher levels of generative actions. @*Conclusion@#Enhancing positive perceptions of older adults among them can boost the subcategories of generativity. This study, which was conducted from an exploratory perspective, has several limitations, including a potential sampling bias. A more comprehensive examination of the relationship between perceptions of older adults and generativity is anticipated in future research.

Hypercalin B alleviates nonalcoholic steatohepatitis progression via suppressing mTORC1 signaling pathway / 药学学报

The global incidence rate of nonalcoholic steatohepatitis (NASH) continues to rise. The pathogenesis of NASH is complex, and there is no effective clinical treatment. Previous study has shown that DEAD box protein 5 (DDX5) can significantly alleviate the NASH process in mice. This study screened the natural product library of the research group and found that the active compound hypercalin B (HB) in Hypericum beanii N. Robson, a traditional Chinese medicine, can upregulate the expression of DDX5 protein in a dose-dependent manner. In this study, an in vitro model of NASH stimulated by palmitic acid (PA) and an animal model of NASH induced by the methionine- and choline-deficient diet (MCD) were constructed. Different concentrations of HB were used to investigate the effect and mechanism of HB in alleviating NASH progression. All animal experiments in this paper were approved by the Ethics Committee of China Pharmaceutical University (NO: 2021-02-003). In vitro model results showed that HB significantly reduced the intracellular lipid deposition induced by free fatty acid (FFA). Animal experiments showed that HB improved liver injury by significantly reducing lipid accumulation in the liver of NASH mice, and reducing serum aspartate transaminase (AST) and alanine transaminase (ALT) levels. Moreover, HB could inhibit liver inflammation by reducing the mRNA levels of liver pro-inflammatory cytokines including interleukin 6 (IL-6), interleukin 1β (IL-1β), and tumor necrosis factor α (TNFα). Further research showed that HB could reduce the phosphorylation level of the mechanical target of rapamycin (mTOR) and reduce the expression of sterol regulatory element binding protein 1 (SREBP1) and fatty acid synthase (FASN), thereby improving lipid metabolism and alleviating NASH progression, and the effects of HB against NASH were dependent on DDX5. In conclusion, HB can improve lipid metabolism and inhibit inflammatory activation by suppressing mTORC1 pathway via upregulating DDX5 protein, and showed promising anti-NASH activity in vitro and in vivo.

Advances on research of structure and function of puromycin sensitive aminopeptidase / 药学学报

Puromycin-sensitive aminopeptidase (PSAP) belongs to the M1 family of aminopeptidases, characterized by the N-terminal substrate binding sequence GAMEN, the enzyme activity center HEXXH(X)18E motif, and the C-terminal ERAP-1-like superfamily structural domain. Encoded by the gene NPEPPS located at 17q21.32, PSAP consists of 919 amino acids and is widely distributed throughout the human body, with the highest expression in the brain, followed by the heart and skeletal muscle. It is also found in the liver, renal tubular epithelium, small intestine, large intestine epithelium, and gastric epithelial cells. PSAP primarily relies on its aminopeptidase hydrolytic activity to remove toxic protein aggregates such as Tau, poly Q, and Cu, Zn-superoxide dismutase 1, making it an important factor in the development of diseases such as Alzheimer's disease, Huntington's chorea, and tumors. Existing PSAP inhibitors include bestatin, amastatin, leuhistin, actinonin, and purinomycin, some of which are already available or in clinical trials. This review provides an overview of the structural and biological functions of M1 family aminopeptidases, with a focus on PSAP, to facilitate further research and targeted drug development.

Design, synthesis, and activity of 5-cyano-2-thiacetyl aromatic pyrimidinone as DENV NS5 RdRp inhibitors / 药学学报

To screen novel anti-dengue virus (DENV) NS5 RdRp enzyme inhibitors, a series of 5-cyano-2-thiacetoaryl pyrimidinone compounds were designed and synthesized by molecular hybridization method with HCV NS5B RdRp inhibitor 3jc and ZIKV NS5 RdRp inhibitor 4w as lead compounds. The anti-DENV activity of these compounds was evaluated by MTT assay and plaque assay and five compounds showed anti-DENV activity. The most active compound 7a'k showed better anti-DENV activity than that of the positive control ribavirin (EC50 = 7.86 μmol·L-1 vs EC50 = 18.07 μmol·L-1), and the other four compounds showed almost the same anti-DENV activity as ribavirin. Finally, the prediction and simulation of the binding mode through molecular provided new ideas for the further development of this new DENV NS5 RdRp inhibitor.

Research progress of multi-source information fusion technology in quality evaluation of traditional Chinese medicine / 药学学报

The quality evaluation of traditional Chinese medicine is one of the key issues related to the modernization of traditional Chinese medicine. The quality evaluation technology system of traditional Chinese medicine mainly includes traditional evaluation (traits, microscopic and physicochemical identification), chemical evaluation and biological evaluation. Due to the complex composition of traditional Chinese medicine, the single detection method in the above evaluation technology system usually cannot obtain sufficient quality information. The multi-source information fusion strategy can organically integrate data from multiple analysis and detection technologies to obtain more comprehensive information of samples and improve the quality evaluation effect. At present, multi-source information fusion strategy has been widely used in the fields of military, industrial and food, and it is still in its infancy in the field of quality evaluation of traditional Chinese medicine. This research introduces the definition, structure, method (algorithm) and fusion level of multi-source information fusion, summarizes its research progress in the origin traceability, variety identification and pharmaceutical analysis of traditional Chinese medicine, and sorts out the specific methods of data fusion in each literature. Finally, we summarized, prospected and discussed the application, development and existing problems of information fusion technology and its application in the quality evaluation of traditional Chinese medicine, in order to provide reference for broadening the application of this technology in the field of traditional Chinese medicine.

Prognostic Predictive Value of ITPKB Mutation's Variant Allele Frequency in Diffuse Large B-cell Lymphoma / 肿瘤防治研究

Objective To investigate the correlation between ITPKB mutation's variant allele frequency (VAF) and prognosis of diffuse large B-cell lymphoma (DLBCL). Methods This study included 155 patients with DLBCL initially diagnosed in the People's Hospital of Xinjiang Uygur Autonomous Region from June 2014 to December 2020. Paraffin-embedded tumor tissue specimens were obtained, and tumor tissue DNA was extracted. A total of 475 hotspot genes including ITPKB were detected by the next generation sequencing to analyze the relationship of the VAF of high-frequency mutant gene with progression-free survival (PFS) and overall survival (OS). Results The mutation frequency of ITPKB was 18.71%. The PFS was significantly shorter in the patients with ITPKB mutations than in those without mutations (37 months vs. 108 months; HR=1.643, 95%CI: 0.920-2.934, P=0.093). The R-language based web tool was used to find the best VAF cutoff to differentiate prognosis. The patients were divided into two groups (VAF High vs. VAF Low+Wt) according to their VAF values. The optimal VAF threshold for ITPKB was 27.48% (HR=3.480, 95%CI: 1.70-7.13, P=0.00027). Multivariate Cox analysis was conducted using clinical indicators such as age, gender, COO classification, IPI, and LDH, and the results showed that PFS was associated with high ITPKB VAF (≥28%) (HR=3.592, 95%CI: 1.738-7.425, P < 0.001) which was an independent adverse predictor of PFS. Conclusion The high load of ITPKB mutation is an independent risk factor for the PFS of patients with DLBCL, and the VAF of ITPKB mutation has a prognostic predictive value for patients with DLBCL.
