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 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 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.

Objective To analyze the pathogenic composition of hand, foot and mouth disease (HFMD) cases and the antibody level of enterovirus 71 (EV-A71) in healthy people in Xi'an in 2022, so as to provide evidence for the prevention and control of HFMD. Methods Anal swabs or stool specimens of HFMD cases were collected. RT-PCR was used to detect enterovirus (EV) and serotype was identified. Enzyme-linked immunosorbent assay (ELISA) was used to detect EV-A71 IgG antibody levels in healthy people. Results A total of 172 positive cases were detected from 274 HFMD clinical specimens with a total detection rate of 62.77%, including 1 case of EV-A71 (0.58%), 95 cases of CV-A16 (55.23%), 64 cases of CV-A6 (37.21%), and 1 case of CV-A10(0.58%). CV-A16 was the dominant pathogen in spring and summer, and CV-A6 was the dominant pathogen in autumn and winter（χ²= 64.376，P＜0.001）. The age of HFMD cases caused by CV-A16 was older than the cases caused by CV-A6（t = 2.709，P = 0.007）. The positive rate of EV-A71 IgG antibodies in healthy people was 36.92% (168/455). The positive rate of EV-A71 IgG antibodies in men (32.35%) was lower than that in women (43.72%), and the difference was statistically significant (χ²= 6.605 , P = 0.014). The positive rate of EV-A71 IgG antibodies in people of all ages ranged from 21.95% to 54.78%, and the difference was statistically significant (χ²= 27.623 , P<0.001). Conclusion The main pathogens of hand, foot and mouth disease in Xi'an in 2022 are CV-A16 and CV-A6 . The positive rate of EV-A71 IgG antibodies in children under 5 years old is low , and EV-A71 vaccination should be strengthened.

ObjectiveTo explore the effects of modified Danggui Beimu Kushen pills on tumor growth and T-cell subsets in H22 hepatocellular carcinoma-bearing mice and to provide an experimental basis for the treatment of hepatocellular carcinoma with modified Danggui Beimu Kushen pills combined with immune checkpoint antibodies. MethodA H22 hepatocellular carcinoma-bearing mouse model was established. The modeled mice were randomized into model， cisplatin， low- （4 g·kg^-1·d^-1）， medium- （8 g·kg^-1·d^-1）， and high-dose （16 g·kg^-1·d^-1） modified Danggui Beimu Kushen pills groups. After continuous administration for 14 days， the mice were sacrificed on day 15. The tumor volume was measured on days 0， 4， 8， 12， 15 of drug administration. Tumors were weighed and thymus index and spleen index were calculated. Spleen lymphocytes were co-cultured with H22 hepatoma cells， and the tumor cell-killing rate was detected by the cell counting kit-8 （CCK-8）. Real-time polymerase chain reaction was carried to determine the mRNA levels of programmed cell death protein-1 （PD-1） and lymphocyte activation gene-3 （LAG-3） in spleen and tumor tissues. The number of CD4⁺ and CD8⁺ T cells and the expression of PD-1 and LAG-3 were detected by immunohistochemistry （IHC）. ResultOn day 8 of drug administration， tumor volumes in all treatment groups decreased compared with that in the model group. On day 15， both tumor volume and tumor weight were significantly lower in the treatment groups than in the model group （P<0.01）， with the cisplatin group showing the most pronounced reduction. Compared with the model and cisplatin groups， medium- and high-dose modified Danggui Beimu Kushen pills increased the thymus index （P<0.01）. Compared with the model group， all treatment groups showed increased spleen index （P<0.05， P<0.01）， with the cisplatin group showing the most significant increase. Compared with the model and cisplatin groups， all the groups of modified Danggui Beimu Kushen pills demonstrated increased number of CD4⁺ and CD8⁺ T cells and tumor cell-killing rate in the spleen and tumor tissues （P<0.01） and down-regulated mRNA and protein levels of LAG-3 （P<0.05， P<0.01）. The high-dose group of modified Danggui Beimu Kushen pills had lower mRNA level of PD-1 in the tumor tissue than the model and cisplatin groups （P<0.01）. ConclusionModified Danggui Beimu Kushen pills may promote the proliferation and tumor microenvironment infiltration of CD4⁺ and CD8⁺ T cells in H22 tumor-bearing mice by down-regulating LAG-3 expression， thereby improving T-cell immune activity and inhibiting tumor growth. This study provides an experimental basis for the combination of modified Danggui Beimu Kushen pills and immune checkpoint antibodies in the treatment of hepatocellular carcinoma.

【Objective】 To investigate the prognostic value of tumor location in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU), and to develop and validate a nomogram model for predicting the overall survival (OS). 【Methods】 UTUC patients undergoing RUN at our hospital during Jan.2010 and Dec.2022 were retrospectively collected, 70% of whom were included in the training group and 30% in the validation group.According to the tumor location, patients were divided into renal pelvis tumor (RPT) group and ureteral tumor (UT) group.The differences in clinicopathological features and prognosis were analyzed.Based on multivariate Cox results, a nomogram model for predicting OS was developed and validated. 【Results】 A total of 366 patients (196 RPT and 170 UT) were included in this study.There were statistically significantly differences in urine cytology (P=0.001), hydronephrosis (P<0.001), history of bladder tumor (P=0.021), pathological T stage (P<0.001) and histological structure (P=0.037) between the two groups.Multivariate Cox results showed that patients with UT had a worse prognosis (HR=2.00, 95%CI: 1.22-3.27, P=0.006).Factors of the nomogram for predicting OS included age, tumor location, lymphovascular invasion and pathological T stage.The model showed good discrimination and calibration, and performed well in internal verification. 【Conclusion】 Compared with RPT, UT has a worse prognosis and the fat around the tumor should be surgically removed more thoroughly to avoid micro-residual.We successfully coustructed a nomogram model that can be used to predict the OS of UTUC patients after RNU surgery.

Lung cancer， the most common malignant tumor， is characterized by a complex pathogenesis and high malignancy， and poses a significant threat to the health and lives of affected individuals. p53 signaling pathway plays a crucial role in the progression of lung cancer and is considered one of the potential targets for targeted therapy. In recent years， multiple studies have indicated that traditional Chinese medicine （TCM） can exert anticancer effects by modulating the p53 signaling pathway. Based on this， this article systematically summarizes the current status and progress of research on TCM intervening in lung cancer by regulating p53 signaling pathway. It was found that TCM formula and preparations， such as Qingjin desheng tablet， Tiaoqi xiaoji decoction， Bufei tongluo jiedu formula， Jianpi bushen formula and Yiqi fuzheng jiedu formula， can promote autophagy and apoptosis of lung cancer cells， inhibit the growth and metastasis of lung cancer cells and strengthen the immune function of the body by activating p53 signaling pathway， thereby inhibiting lung cancer. TCM monomers， such as pseudoginsenoside-Rh2， saikosaponin D， polyphyllin Ⅶ， dendrobiine， sophoridine， gambogic acid， triptolide and triptolide succinate monoester YJ-4， can accelerate cell apoptosis， inhibit the proliferation of lung cancer cells and regulate cell cycle by activating p53 signaling pathway， thereby inhibiting lung cancer.
