Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

OBJECTIVE To standardize the management of patients’ self-carried medicines dispensed by Pharmacy Intravenous Admixture Services （PIVAS） of our hospital， improve the quality of medical care， and ensure the safety of patients’ medication. METHODS Based on evidence-based methodology， the research literature of domestic medical institutions on the management of patients’ self-carried medicines was systematically searched and analyzed， and the data on the use of patients’ self- carried medicines in our hospital from February to April 2023 were extracted based on our hospital’s information system. A fishbone diagram of the difficulties in constructing patients’ self-carried medicines within PIVAS of our hospital was drawn through brainstorming， thereby establishing a refined whole-process management system for patients’ self-carried medicines in PIVAS. The effectiveness of the system was evaluated through the indicators， including dispensing volume， error rate， and so on. RESULTS & CONCLUSIONS A total of 15 papers were included， covering descriptive studies on the reasons for the use of patients’ self- carried medicines， current status of their use， management system， management methods， management suggestions. There were 12 clinical departments in our hospital with a high proportion of patients using self-carried medicines， among which the pediatric neurology department had the most use of patients’ self-carried medicines， accounting for 10.65%. In terms of dosage form， injectable drugs accounted for 13.68%， all of anticancer drug were uniformly dispensed by our hospital’s PIVAS. PIVAS in our hospital had successfully constructed the management system for dispensing patients’ self-carried medicines， which included the processes of drug reception and preservation， medical document retention， doctor’s order review， drug placement， dispensing， review and transportation. After the implementation of the system， from May 2023 to October 2024， our hospital’s PIVAS dispensed 654 bags of patients’ self-carried medicines in total，with a monthly average of 36 bags. Zero error management 5）；was realized for all patients’ self-carried medicines. The system operates stably and effectively， thereby ensuring the high-quality dispensing of patients’ self-carried medicines in PIVAS of our hospital.

Objective To investigate the effect of palmitoleic acid(POA)on pyroptosis of cardiomyocytes after hy-poxia/reoxygenation-induced injury in the human myocardium.Methods The experiment comprised a control group(Control,normal culture),a hypoxia/reoxygenation group(HR),a palmitoleic acid-treated group(HR+POA),and an anhydrous ethanol control group(HR+ET).Cardiomyocytes viability was assessed using CCK-8 assay,and the level of pyroptosis of cardiomyocytes was measured through the double staining with Hoechst33342/PI and LDH assay.ELISA was employed to detect the release of inflammatory factors IL-1 β and IL-18 in the cell culture supernatant.qRT-PCR and Western blot were utilized to determine the relative expression levels of mRNA and protein of pyroptosis-related genes,namely NLRP3,ASC,Caspase-1,GSDMD,IL-1 β and IL-18,respective-ly.Results CCK-8 assay showed that the survival of hypoxic/reoxygenated cardiomyocytes increased with the ad-dition of POA at concentrations ranging from 25 to 100 μmol/L,as compared to the HR group;a hypoxia/reoxy-genation model of cardiomyocyte was established.The expression of protein and mRNA increased in NLRP3,ASC,Cleaved caspase-1,GSDMD-N,IL-Iβ and IL-18 vs the control group(P＜0.05),the positive percentage of Ho-echst33342/PI staining in cardiomyocytes increased significantly(P＜0.05),the release of LDH,IL-Iβ,and IL-18 increased(P＜0.05).After intervention with 100 μmol/L POA,the protein and mRNA expression levels of NLRP3,ASC,Cleaved caspase-1,GSDMD-N,IL-Iβ,and IL-18 were significantly reduced in the HR+POA group vs HR+ET group(P＜0.05).The positive percentage of Hoechst33342/PI staining in cardiomyocytes de-creased significantly,and the levels of LDH,IL-Iβ and IL-18 significantly decreased(P＜0.05).Conclusion Palmitoleic acid may alleviate hypoxia/reoxygenation-induced injury of cardiomyocytes by inhibiting pyroptosis and inflammatory response after hypoxia/reoxygenation in human myocardium.

Objective To evaluate the value of systemic inflammatory markers(SIM)in the prognosis of patients with bladder cancer undergoing radical cystectomy.Methods Clinical data of 233 patients with bladder cancer who underwent radical cystectomy in the Affiliated Hospital of Xuzhou Medical University during Dec.2011 and Nov.2020 were retrospectively collected,the SIM score was calculated and patients were grouped.Progression-free survival(PFS)was assessed with Kaplan-Meier analysis,and differences between groups were compared with log-rank test.Factors affecting PFS were analyzed with Cox proportional risk model.The patients were randomly divided into a training set(n=164)and a verification set(n=69)according to 7:3 ratio,and a nomogram model was established and verified.Results Cox regression analysis showed that SIM score and pathological T staging were independent predictors of PFS(P＜0.05).A predictive model was established based on SIM score and pathological T staging.The area under the receiver operating characteristic(AUC)curve for predicting 1-year,3-year,and 5-year PFS were 0.939,0.943,and 0.943,respectively.After the model was applied to evaluate the validation set,the performance was still stable.Conclusion The prediction model based on SIM score and clinicopathological T staging can accurately predict the survival of patients with bladder cancer after radical cystectomy,and can be used to guide individualized treatment of patients.

Objective:To investigate the genetic and evolutionary characteristics of hemagglutinin (HA) and neuraminidase (NA) genes of influenza B/Victoria (BV) virus in Xi′an city from 2019 to 2023.Methods:Twenty-five BV strains isolated from the Xi′an influenza surveillance network laboratory between 2019 and 2023 were collected. The HA and NA genes were sequenced using MiniSeq high-throughput sequencing platform. An evolutionary tree was constructed using bioinformatics software to analyze homology and mutation sites, and to predict N-glycosylation sites online. The antigenicity of the strains was analyzed through hemagglutination inhibition tests.Results:The BV influenza in Xi′an exhibited a distinct seasonal transmission pattern from 2019 to 2023, with peak prevalence occurring during the winter and spring seasons. The evolutionary analysis of the HA genes shows that the strains from Xi′an in 2019 belong to the V1A.3 branch, and the strains from 2021 to 2023 belong to the V1A.3a.2 branch. Analysis of antigenic sites showed that there were variations in 6 sites of 3 antigenic determinants in the HA proteins of the BV strains from 2021-2022 compared to 2019, and 2 sites of 1 antigenic determinant changed in the HA proteins in 2023 compared to 2021-2022. The evolutionary analysis of the NA genes indicates that the BV strains from Xi′an in 2019 belong to the A. 1.1 branch. By 2021 and 2022, it had evolved into the A. 1.2 clade, and by 2023, it had further evolved into the B clade and its derivatives, with no strains showing mutations associated with resistance to NA inhibitors. Antigenic analysis indicated that the majority of BV strains in Xi′an were similar to the strains included in the vaccine composition. Furthermore, glycosylation analysis showed that the potential N-glycosylation sites in the HA proteins of BV strains from 2021-2023 were reduced by one compared to those from 2019, and only a few strains from 2023 displayed alterations in the potential N-glycosylation sites of the NA proteins.Conclusions:The HA and NA genes of the BV strains from 2019 to 2023 are continuously mutating and evolving into new branches. Since 2021, V1A.3a.2 has become the dominant evolutionary branch of the HA genes, while the evolutionary branches of the NA genes from 2019 to 2023 have been continuously changing.

Purpose To investigate the expression of C1GALT1 in gastric cancer and its effect on the biological be-havior of BGC-823 in gastric cancer cells.Methods The ex-pression of C1GALT1 mRNA and protein in gastric cancer tis-sues and normal gastric mucosa,gastric cancer cells and normal gastric mucosal cells was analyzed by bioinformatics,qRT-PCR and Western blot;the transient transfection of siRNA into BGC-823 cells was designed with C1GALT1 cDNA sequence as the target.Transwell assay was used to detect the effect of C1GALT1-siRNA on the migration and invasion ability of BGC-823 cells in gastric cancer.Western blot method detected the expression of epithelial-mesenchymal transition(EMT)-related proteins in BGC-823 after transfection of C1GALT1-siRNA.Re-sults C1GALT1 was highly expressed in gastric cancer tissues and cell lines BGC-823,SGC-7901 and MGC-803,and the ex-pression levels were positively correlated with gastric cancer pathological stages Ⅰ and Ⅱ(P＜0.05).After interfering with C1GALT1 in BGC-823 cells,the ability of migration and inva-sion decreased(P＜0.05),epithelial cell markers E-cadherin and Claudin-1 protein expression increased,while mesenchymal cell markers vimentin and Slug protein expression decreased(P＜0.05).Conclusion C1GALT1 is highly expressed in gastric cancer tissues and cells,silencing of C1GALT1 can inhibit mi-gration and invasion ability of gastric cancer,the mechanism may be related to EMT.

Objective:To explore the relevant factors affecting the efficacy of microscopic spermatic cord surgery and build a predictive model for postoperative pain relief.Methods:A retrospective analysis was conducted on the clinical data of 324 patients with spermatic cord pain who visited the Department of Urology at Peking University People's Hospital between October 2015 and April 2023.This cohort included 212 patients with varicocele-related spermatic cord pain and 112 patients with idiopathic sper-matic cord pain.All the patients underwent microsurgical procedures:varicocele-related pain was treated with microsurgical varicocelectomy,and idiopathic pain was treated with microsurgical denervation of the spermatic cord.The patients were categorized into effective and ineffective groups based on whether their pain had decreased by more than 50％six months post-surgery compared with pre-surgery levels.Base-line data were preliminarily screened for clinical indicators using t tests and univariate analysis.Clinical predictor variables[age,duration of pain,diameter of varicocele,patient health questionnaire-9(PHQ-9)score,generalized anxiety disorder-7(GAD-7)score]were selected using Lasso regression.Aclini-cal prediction model for effective pain relief following microscopic spermatic cord surgery was constructed using Logistic regression and presented as a nomogram.The model's internal validation was performed using the bootstrap method.Its predictive power and clinical utility were evaluated through the concor-dance index,the area under the receiver operating characteristic curve,and calibration plots.Results:Post-microscopic varicocele ligation,156 patients(73.58％)experienced significant pain relief,as did 94 patients(83.93％)following microscopic denervation.Independent predictors for postoperative out-comes included age,PHQ-9 score,GAD-7 score,chronic pain duration,and varicocele diameter,diffe-ring slightly between varicocele-related and idiopathic pain groups.The models demonstrated excellent predictive ability,with areas under the curve of 0.909 and 0.913 for varicocele and idiopathic groups,respectively,and high concordance indices.Conclusion:The postoperative efficacy prediction model based on age,pain duration,PHQ-9 score,GAD-7 score,and varicocele diameter has good predictive ability and clinical applicability,and can be used in clinical practice.

Objective To investigate the effect and mechanism of recombinant human CC16 protein(rhCC16)on cigarette smoke extract(CSE)-induced senescence of human bronchial epithelial cells(HBECs).Methods CCK-8 assay was used to evaluate the cell viability in HBECs after treated with 0％,1％,2.5％,5％,7.5％and 10％CSE and/or 0,10,100,250 and 500 ng/mL rhCC16.β-galactosidase staining was used to observe the activity of the enzyme in control,CSE,and CSE+rhCC16 treated HBECs.The mRNA levels of P16 and P21 in above cell groups were detected by real-time fluorescence quantitative PCR(qPCR),and the protein levels of P16,P21,p-P53,P38,p-P38,ERK1/2 and p-ERK1/2 were detected with Western blot in control group,CSE and CSE+rhCC16 groups.Results Compared with the control group,5％CSE stimulation for 72 h or the treatment of 500 ng/mL or lower dose of rhCC16 had no significant effect on cell viability of HBECs.Stimulation 5％CSE for 72 h resulted in significantly higher positive rate to β-galactosidase staining(P＜0.05),elevated mRNA and protein levels of P16 and P21(P＜0.05),and enhanced protein levels of p-P53,p-P38 and p-ERK1/2(P＜0.05)when compared with the control group.Compared with the simple CSE stimulation,250 ng/mL 1hCC16 treatment decreased positive rate to β-galactosidase staining(P＜0.05),reduced mRNA and protein levels of P16 and P21(P＜0.05)and protein levels of p-P53,p-P38 and p-ERK1/2(P＜0.05).Conclusion rhCC16 inhibits CSE-induced cellular senescence of HBECs,which may due to its suppression in P38 MAPK and ERK1/2 signaling pathway.
