AIM:This study aims to examine the ependymin-related protein 1(EPDR1)expression in various tissues from wild-type C57BL/6 mice and type 2 diabetes(db/db)mice.The impact of EPDR1 on lipid accumulation in al-pha mouse liver 12(AML12)hepatocytes was also investigated.METHODS:Western blot was used to detect EPDR1 protein expression in the heart,liver,spleen,lung,kidney,gastrocnemius,brown adipose and brain tissues of C57BL/6 mice.Western blot and immunohistochemical(IHC)staining were also used to compare EPDR1 protein expression in the liver,gastrocnemius muscle,heart and kidney tissues of db/db and C57BL/6 mice.To develop an AML12 cell lipid deposi-tion model,palmitic acid(PA)+oleic acid(OA)was used,and the cells were transfected with adenovirus overexpressing EPDR1 or treated with exogenous recombinant EPDR1 protein(rEPDR1).ELISA was conducted to determine intracellu-lar triglyceride(TG)content,and oil red O staining was employed to assess the effect of EPDR1 on lipid accumulation in AML12 cells.RESULTS:Western blot and IHC staining results revealed that EPDR1 was widely expressed in various tis-sues of wild-type mice,with the liver exhibiting the highest protein expression level.However,EPDR1 expression was down-regulated in the liver,gastrocnemius muscle,heart and kidney tissues in diabetic db/db mice compared with wild-type mice.Oil red O staining revealed that overexpression of EPDR1 in AML12 liver cells or rEPDR1 treatment led to re-duced lipid accumulation.Furthermore,the TG content significantly decreased compared with the model group(P<0.05).CONCLUSION:EPDR1 is expressed in various tissues of wild-type mice,but showed diminished expression in the liver tissues of diabetic mice.Nevertheless,enhancing the expression of EPDR1 can aid in reducing lipid accumula-tion in hepatocytes.These findings provide an experimental foundation for further exploration of the role of EPDR1 in the development of fatty liver in diabetic liver tissue.

Objective To collect data related to nursing quality,describe and analyze the application effect,and explore its application value by combining the contents of key contents of nursing quality control with information technology in clinical nursing work.Methods Based on the clinical nursing quality control information system currently operated in Yichun People's Hospital,actual contents of nursing quality control were incorporated into the system,focusing on key links of nursing quality control,such as patient identification management,medication safety management,doctor's order check management,nursing document writing,overall nursing responsibility system,and health education management.Additionally,the study compared the performance of these quality control points before and after the integration of information technology.Results Following the inte-gration of key quality control contents in nursing with information technology,all departments of the hospital achieved a signifi-cantly higher pass rates for patient identification management,medication safety management,doctor's order check management,health education management,and follow-up rates of discharged patients(P＜0.05),while they had a significant decrease in the incidence of fall injuries,in-hospital pressure injuries,and unplanned extubation among inpatients(P＜0.05).Additionally,the time for post-ward nursing data extraction,problem feedback,and correction cycle was significantly shortened after implemen-tation(P＜0.05).Conclusion The information-oriented key contents of nursing quality control yields effectiveness in enhancing the performance of various quality control measures and reducing the occurrence of adverse events such as fall injuries and pres-sure injuries.This integration allows for more accurate data collection,improves patient follow-up rates,and facilitates timely ad-justments in nursing practices.The study recommends utilizing scientific methods to extract reliable monitoring information,en-hance data accuracy,and minimize adverse events.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective:To compare the efficacy of endoscopic submucosal dissection (ESD) and modified-endoscopic mucosal resection (M-EMR) for G1 rectal neuroendocrine tumors (RNETs) .Methods:Data of 121 patients with pathologically confirmed G1 RNETs treated with ESD ( n=105) or M-EMR ( n=16) in Nanjing Drum Tower Hospital from January 2017 to September 2020 were retrospectively analyzed. The complete resection rate, complication incidence, hospital stay, treatment cost and other indicators of the two groups were compared by using inverse probability of treatment weighting (IPTW). Results:There were significant differences in tumor number ( χ2=8.76, P=0.003), tumor invasion depth ( χ2=6.96, P=0.008), utilization of metal clips [82.9% (87/105) VS 93.8% (15/16), χ2=8.78, P=0.003], number of metal clips ( χ2=8.41, P=0.016), hemostasis using hot clamp [78.1% (82/105) VS 18.7% (3/16), χ2=20.64, P<0.001], traction procedure [2.9% (3/105) VS 18.7% (3/16), χ2=4.45, P=0.035] and treatment cost (17 568.6 ± 8 911.0 yuan VS 8 120.8±1 528.2 yuan, t=3.65, P<0.001) between the ESD group and the M-EMR group. After verifying the stability of the results using IPTW sensitivity analysis, there was still significant difference in the treatment cost ( t=2.07, P<0.001). Conclusion:Both ESD and M-EMR demonstrate comparable efficacy in treating G1 RNETs; however, M-EMR exhibites lower treatment costs.

African swine fever virus (ASFV) infection leads to a mortality rate of up to 100%, causing devastating disasters to the pig industry. Understanding the ASFV infection and replication is therefore of great importance. ASFV has more than 150 open reading frames, among which the inner coat protein p17 encoded by the D117L gene is involved in the formation of the icosahedral structure of the virus. However, little is known about the mechanism how p17 regulates host cell function. In this study, the potential host proteins interacting with ASFV p17 were screened by immunoprecipitation technique combined with protein profiling analysis. The interactions of p17 with mitochondrial membrane protein TOMM70 and heat shock protein HSPA8 were confirmed by co-immunoprecipitation technique and laser confocal experiments. This study provides important information for further exploring the function of p17 during ASFV infection.

OBJECTIVE: To compare the efficacy and safety of combined radiofrequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) with RFA alone for hepatocellular carcinomas (HCC). MATERIALS AND METHODS: Randomized controlled trial (RCT) studies that compared the clinical or oncologic outcomes of combination therapy of TACE and RFA versus RFA for the treatment of HCC were identified through literature searches of electronic databases (Pubmed, Embase, Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure, and Google Scholar). Hazard ratios (HRs) or odds ratios (ORs) with their corresponding 95% confidence interval (CI) were combined as the effective value to assess the summary effects. The strength of evidence was rated by the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: Six RCTs with 534 patients were eligible for inclusion in this meta-analysis. The meta-analysis showed that the combination of TACE and RFA is associated with a significantly longer overall survival (HR = 0.62, 95% CI: 0.49-0.78, p < 0.001) and recurrence-free survival (HR = 0.55, 95% CI: 0.40-0.76, p < 0.001) in contrast with RFA monotherapy. The seemingly higher incidence of major complications in the combination group compared with RFA group did not reach statistical significance (OR = 1.17, 95% CI: 0.39-3.55, p = 0.78). CONCLUSION: In patients with HCC, the combination of TACE and RFA is associated with significantly higher overall survival and recurrence-free survival, as compared with RFA monotherapy, without significant difference in major complications.
