Objective:To investigate the effect of a rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings in the postoperative care of children undergoing radical operation on Hirschsprung's disease.Methods:A total of 91 children with Hirschsprung's disease and their parents who underwent radical surgery at the Children's Hospital Affiliated to Zhengzhou University (Henan Children's Hospital, Zhengzhou Children's Hospital) between January 2022 and January 2024 were selected by convenience sampling. Using a computer-generated random number table, they were randomly divided into an intervention group ( n=46) and a control group ( n=45). The control group received routine surgical nursing, while the intervention group received a rapid rehabilitation nursing model based on Rogers' theoretical framework in addition to routine care. Postoperative pain stress, anorectal function, gastrointestinal functional recovery, and parental satisfaction were compared between the two groups. Results:On the third postoperative day, the intervention group had lower scores on the FLACC scale, better anorectal function, and shorter times to first bowel sound, first anal exhaust, and first defecation than the control group. The overall parental satisfaction rate in the intervention group was 86.96% (40/46), higher than 51.11% (23/45) in the control group, and the differences were statistically significant (all P<0.05) . Conclusions:The rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings showed significant effectiveness in children undergoing radical operation on Hirschsprung's disease. It reduced postoperative pain, promoted recovery of anorectal and gastrointestinal function, and improved parental satisfaction.

Objective:To explore the predictive value of systemic immune inflammation index combined with stress response index for postoperative urinary tract infection in patients with complicated kidney stones.Methods:From June 2021 to June 2023,97 patients who underwent treatment for urinary tract infection after complex kidney stone operation in Cangzhou Hospital of Integrated Traditional and Western Medicine were selected as infected group,and 87 patients who did not develop urinary tract infection after complex kidney stone operation were selected as uninfected group.Systemic immunoinflammatory index(SII),neutrophils,lympho-cyte,platelet,malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT)levels were detected.Multivariate Logistic regression analysis was performed to analyze risk factors of postoperative urinary tract infection,and ROC curve was drawn to analyze the predictive value of SII,MDA,SOD and CAT alone and combined detection for postoperative urinary tract infection in patients with complex kidney stones.Results:Compared with uninfected group,levels of SII,neutrophils and MDA were increased in infected group,while levels of SOD and CAT were decreased(P<0.05).Levels of lymphocytes and platelets were decreased,the difference was not statistically significant(P>0.05).Multivariate Logistic regression analysis showed that presence of urinary tract history,opera-tion time≥100 min,urinary catheter retention time≥7 d,presence of preoperative urinary tract infection,stone load≥1 000 mm2,combined renal dysfunction,and preoperative blood glucose≥6.15 mmol/L were main risk factors for postoperative urinary tract infection in patients with complex kidney stones.ROC curve showed that combined detection was significantly more effective than single detec-tion of SII,MDA,SOD and CAT in the diagnosis of postoperative urinary tract infection in patients with precomplex kidney stones.Conclusion:Patients with urinary tract infection after complicated kidney stones have increased SII and MDA,decreased SOD and CAT levels,and the abnormal increased or decreased expression level are the predictors of risk of urinary tract infection after compli-cated kidney stones,which may be related with the diagnosis,development and prognosis of the disease.

Objective To analyze the changes in angiopoietin-2(Ang-2)levels before and after microwave ablation(MWA)in patients with high-risk pulmonary nodule and its impact on postoperative recurrence.Method A total of 94 patients with high-risk pulmonary nodules admitted to Guizhou Aerospace Hospital from December 2019 to December 2021 were included and categorized into a recurrence group(n=30)and a non-recurrence group(n=64).Clinical data was compared between the two groups.Pearson correlation analysis was used to analyze the correlation between pre-treatment angiopoietin-2(Ang-2)levels and CT parameters.Logistic regression model,restricted cubic splines,threshold effect analysis,and receiver operating characteristic(ROC)curve were used to analyze the relationship between pre-treatment Ang-2 levels and postoperative recurrence.Kaplan-Meier survival curves were used to analyze the differences in overall survival among patients with different Ang-2 levels.Cox regression model was used to analyze the factors affecting patients'survival.Result Compared to pre-treatment levels within the same group,Ang-2 levels in both groups decreased significantly,with statistically significant differences(P<0.05).Pearson correlation analysis showed that pre-treatment Ang-2 levels were positively correlated with BF,BV,PS,and MTT.Ang-2 level was independently associated with postoperative recurrence.Results of ROC analysis indicated that pre-treatment Ang-2 had certain predictive value for postoperative recurrence(area under the curve=0.789).Restricted cubic spline analysis revealed a nonlinear dose-response relationship between pre-treatment Ang-2 and postoperative recurrence(P<0.05).Threshold effect analysis identified that the inflection point of Ang-2 affecting recurrence as 1905.41 pg/mL.Survival analysis demonstrated that the median overall survival of patients in the Ang-2<1905.41 pg/mL group was longer than that in the Ang-2≥1905.41 pg/mL group(P=0.039).Furthermore,Ang-2≥1905.41 pg/mL was an independent factor affecting patients'survival time.Conclusion The levels of Ang-2 decreased significantly in patients with high-risk pulmonary nodules after MWA,and pre-treatment Ang-2 level has certain predictive value for postoperative recurrence.

Traditional development of small protein scaffolds has relied on display technologies and mutation-based engineering, which limit sequence and functional diversity, thereby constraining their therapeutic and application potential. Protein design tools have significantly advanced the creation of novel protein sequences, structures, and functions. However, further improvements in design strategies are still needed to more efficiently optimize the functional performance of protein-based drugs and enhance their druggability. Here, we extended an evolution-based design protocol to create a novel minibinder, BindHer, against the human epidermal growth factor receptor 2 (HER2). It not only exhibits super stability and binding selectivity but also demonstrates remarkable properties in tissue specificity. Radiolabeling experiments with ^99mTc, ⁶⁸Ga, and ¹⁸F revealed that BindHer efficiently targets tumors in HER2-positive breast cancer mouse models, with minimal nonspecific liver absorption, outperforming scaffolds designed through traditional engineering. These findings highlight a new rational approach to automated protein design, offering significant potential for large-scale applications in therapeutic mini-protein development.

Objective To explore the effect of transjugular intrahepatic portosystemic shunt(TIPS)on gut microbiota and blood ammonia level in patients with decompensated cirrhosis,and to analyze the correlation between the gut microbiota and blood ammonia level.Methods From July 2021 to December 2023,the patients with decompensated cirrhosis and portal hypertension complicated by esophagogastric variceal bleeding and/or refractory ascites,who received TIPS at Zhuhai Hospital of Guangdong Provincial Hospital of Traditional Chinese Medicine,were collected.The blood and stool samples were collected before and after TIPS.The changes in blood routine,prothrombin time,liver function,and blood ammonia level were determined.The change of gut microbiota was detected using 16S rRNA high-throughput sequencing,and Spearman correlation analysis was used to assess the correlation between the gut microbiota and blood ammonia level.Results In 20 patients,the post-TIPS one-month levels of AST,TBil,DBiL,PT,and blood ammonia were higher than their pre-TIPS values(P＜0.05),and the albumin(Alb)level was lower than the pre-TIPS value(P＜0.05).The post-TIPS 3-month levels of TBil,DBil,PT,and blood ammonia were higher than their pre-TIPS values(P＜0.05).One month after TIPS,the beta diversity of the gut microbiota became significantly different from the pre-TIPS pattern(P＜0.05).After TIPS,the harmful bacteria such as Veillonella,Streptococcus and Haemophilus were significantly reduced,the difference was statistically significant(P＜0.05).The correlation analysis of gut microbiota and blood ammonia level showed that in T0 group Colidextribacter was positively correlated with blood ammonia level,while Roxobella was negatively correlated with blood ammonia level;and in T1 group,Colidextribacter and Streptococcus were positively correlated with blood ammonia level,while Coprococcus,Bifidobacterium and Parasutterella were negatively correlated with blood ammonia level,and the differences were statistically significant(all P＜0.05).Conclusion In patients with decompensated cirrhosis after receiving TIPS,significant changes in the pattern of gut microbiota occur.Certain correlations exist between the changes of some microbiota and blood ammonia levels.Regulating the intestinal microecology may contribute to reducing blood ammonia level after TIPS.
