Objective:To investigate the effects of ATG5 and ATG7 genes on the sensitivity of multiple myeloma(MM)cell line RPMI-8226 cells to ferroptosis.Methods:CRISPR/Cas9 technology was used to knock out the autophagy key genes ATG5 and ATG7 in RPMI-8226 cells.Western blot was used to identify gene knockout cells,and detect the expression changes of autophagy-related proteins P62 and LC3B.Flow cytometry was used to detect the change of sensitivity of gene knockout cells to RSL3.The content of intracellular ferrous ions and reactive oxygen species(ROS)level in gene knockout cells were detected.Results:Western blot result confirmed that ATG5 and ATG7 genes were knocked out successfully in RPMI-8226 cells.The result of flow cytometry showed that the cell viability of RPMI-8226 cells was dose-dependent on different concentrations of RSL3(r=-0.969).RSL3(10 μmol/L)was used to induce ferroptosis in cells of control group and gene knockout groups,then the cell viability in gene knockout groups were both higher than control group after 48 hours(both P＜0.001).After knocking out the ATG5 and ATG7 genes,the content of intracellular Fe2+decreased significantly compared with control group(both P＜0.01),and the ROS level also decreased(both P＜0.001).Conclusion:Knockout of ATG5 and ATG7 genes can inhibit the ferroptosis of MM cells,and LAP pathway may be involved in the regulation.

Objective:To investigate the laboratory detection methods for immune hemolytic transfusion reactions caused by anti-tigecycline antibody and the clinical diagnosis and treatment of one patient.Methods:The correlation between hemolysis-related laboratory indexes of the patient and the duration of medication was analyzed. Blood samples of the patient were tested using direct anti-human globulin test, free antibody test, and release test. Erythrocyte sensitization method and immune complexome analysis were used to detect the antibody against tigecycline in the serum of the patient. The properties and the titers of anti-tigecycline antibody were analyzed.Results:Anti-tigecycline antibody was found in the patient through the erythrocyte sensitization method and the immune complexome analysis, and the result of the direct anti-human globulin test was positive. The clinical symptoms and physical signs of the patient improved rapidly after withdrawal of tigecycline and blood transfusion. The patient was discharged after 14-day treatment with immunoglobulin and hormone.Conclusions:Tigecycline can cause hemolytic transfusion reactions. Serological tests are essential for the diagnosis of drug-induced hemolytic anemia. Withdrawal of medications and symptomatic treatment should be conduceted immediately when patients develop drug-related hemolytic anemia.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

Objective To investigate the relationship between insomnia,gastrointestinal symptoms,and glycosylated hemoglobin(HbA1c)levels in individuals diagnosed with type 2 diabetes mellitus(T2DM),as well as the related influencing factors.Methods A total of 910 T2DM patients treated in our multicenter from January 2022 to December 2022 were enrolled in this study.General information(gender,age,smoking and drinking history,exercise,course of disease,treatment and complications),HbA1c,Athens Insomnia Scale(AIS)scores and Gastrointestinal Symptoms Rating Scale(GSRS)scores of patients were collected.The differences of sleep and gastrointestinal symptoms between groups were analyzed,and the correlation between the differences and HbA1c was analyzed.Furthermore,the risk factors for non-standard HbA1c were analyzed.Results The AIS score and GSRS score in the HbA1c control group were less than those in the non-standard group(P＜0.01).Insomnia was reported by 37.0％of T2DM patients,and the HbA1c level in the insomnia group was significantly higher than that in the non-insomnia group(10.00％±2.38％vs.8.26％±1.73％,P＜0.01).Gastrointestinal symptoms were present in 57.5％of T2DM patients,and the HbA1c levels in the group with gastrointestinal symptoms were significantly higher than those in the group without gastrointestinal symptoms(9.26％±2.23％vs.8.43％±1.98％,P＜0.01).Furthermore,26.3％of T2DM patients experienced both insomnia and gastrointestinal symptoms.Remarkably,the HbA1c levels in the group with both insomnia and gastrointestinal symptoms were significantly higher than those in the group without either condition(10.18％±2.44％vs.8.45％±1.86％,P＜0.01).Correlation analysis demonstrated a significant association between sleep quality,gastrointestinal function,and HbA1c levels(P＜0.01).The logistic regression analysis result revealed that age,GSRS score,AIS score,and the presence of insomnia combined with gastrointestinal symptoms were independent risk factors for predicting HbA1c≥6.5％(P＜0.01).Having both insomnia and gastrointestinal symptoms concurrently was the strongest risk factor for substandard HbA1c control,and the risk of blood sugar control may increase about 5 times when both appear together.Conclusion Insomnia and gastrointestinal symptoms are common comorbidities in T2DM patients,showing a cross-interfering relationship,and they appear together with poor blood sugar control,interact causally,and amplify each other.

Objective:To investigate and analyze the use and duration of anti-seizure medications (ASMs) in patients with chronic epilepsy after autoimmune encephalitis (AE), as well as the effect of ASMs use on the formation of this epilepsy to provide relevant evidence for the choice of ASMs in patients with acute seizure or chronic epilepsy after AE.Methods:A retrospective follow-up study was performed on AE patients (including patients with antibody-negative autoimmune limbic encephalitis) diagnosed in the Affiliated Brain Hospital of Nanjing Medical University from December 1, 2013 to October 31, 2022. The dates of the first seizure onset and the chronic epilepsy formation (defined as 1 year after immunotherapy) were recorded. The initial time, types and numbers of ASMs used in acute symptomatic seizure (ASS) and the maintenance time, types and numbers of ASMs in chronic epilepsy period (the continuation or the combined therapy of ASMs) were collected, respectively. A Logistic regression model was used to analyze multi-influencing factors on the formation of chronic epilepsy after AE.Results:A total of 332 patients were enrolled in this study, of whom 32.5% (108/332) with antibody-negative autoimmune limbic encephalitis. In total, 54.8% (182/332) of patients were males, and the age of onset was (40.7±19.7) years. Finally, 81.0% (269/332) of participants manifested ASS, and 57.2% (190/332) developed chronic epilepsy up to the last follow-up. The follow-up time was 1-8 years, with a median of 2 years. All patients received ASMs treatment during ASS period. Among the ASS patients, 48.0% (129/269) were prescribed monotherapy of ASMs, and 52.0% (140/269) were given the combined therapy of ASMs. Of all the patients with ASMs, 70.3% (189/269) were given early ASMs treatment (within 24 hours of the seizure onset), and 29.7% (80/269) were given delayed ASMs treatment. Subsequently, 81.0% (218/269) of the ASS patients continued the ASMs treatment (>6 months), and 19.0% (51/269) stopped use of ASMs. In the chronic epilepsy stage, 79.5% (151/190) of thee epilepsy patients continued ASMs, of whom 37.1% (56/151) were treated with monotherapy, and 62.9% (95/151) were treated with combined therapy. The incidence of chronic epilepsy was 81.3% (65/80) in the delayed ASMs treatment group, higher than the 66.1% (125/189) in the early ASMs treatment group,with statistically significant difference (χ 2=6.189, P=0.013). There were no statistically significant differences in the ASMs types and whether combined therapy of ASMs was used between chronic epilepsy group and non-chronic epilepsy group. The Logistic regression model showed that delayed ASMs treatment ( OR=2.306,95% CI 1.032-6.387, P=0.018), positive anti-neuronal intracellular antibodies ( OR=2.626,95% CI 1.536-9.531, P=0.004,compared with anti- neuronal surface antibodies), abnormal brain magnetic resonance imaging ( OR=9.883,95% CI 3.608-27.071, P<0.001), elevated cerebrospinal fluid protein ( OR=2.874,95% CI 1.115-7.409, P=0.029), and abnormal electroencephalogram ( OR=9.287,95% CI 3.767-22.896, P<0.001) were independent risk factors for chronic epilepsy after AE. Conclusions:The development of chronic epilepsy after AE is associated with the occurrence of ASS and the delayed use of ASMs, but the type of ASMs or whether the combined ASMs therapy is used is not associated with the formation of chronic epilepsy after AE. It is concluded that early ASMs treatment for the AE patients with ASS may reduce the incidence of chronic epilepsy. For AE patients with ASS who have undergone early standardized treatment, long-term, combined ASMs treatment may not be necessary.

Objective To investigate the possible mechanism of action of Jinqi Qingshu granules(JQQSG)in the treatment of community-acquired pneumonia(CAP)by network pharmacology and molecular docking technology.Methods The TCMSP database and SwissTargetPrediction database were used to obtain and screen the active ingredients and targets of JQQSG,and GeneCards,OMIM,TTD,and DisGeNET databases were used to search for the predicted targets of CAP,and the two targets were mapped and then imported into STRING database to construct a PPI network to screen the key targets,and then the GO and KEGG pathway enrichment were analyzed by the DAVID database,and molecular docking was carried out by the AutoDock Tools software.Results 209 active ingredients and 1 041 targets of JQQSG were obtained after screening;312 targets were co-activated with CAP,and 64 core targets were obtained after PPI network screening.571 biological processes,68 cellular components,and 199 molecular functions were analyzed by GO enrichment,and 165 KEGG pathways were analyzed by KEGG pathway enrichment,mainly involved in protein action,apoptosis and MAPK signaling pathway.Molecular docking suggests that the core target and the core components all have good binding ability.Conclusion The mechanism of action of JQQSG in the treatment of CAP may be related to its regulation of Akt,MAPK signaling pathway,improvement of oxidative stress,and other pathways to exert anti-inflammatory and antioxidant effects,which could lay the foundation for further in-depth study of its specific mechanism of action.

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.
