Objective To construct a graded nursing program for exercise rehabilitation of children with hematopoietic stem cell transplantation(HSCT)and carry out a preliminary application,aiming to provide a basis for healthcare personnel to guide the exercise rehabilitation of children with HSCT.Methods Literature analysis and Delphi expert correspondence were used to construct a graded nursing program of exercise rehabilitation for children with HSCT.Through the convenience sampling method,children with HSCT in the hematology department of a tertiary-level children's hospital in Suzhou City were selected as the study subjects from June-December 2023,of which 26 children with HSCT from September-December 2023 served as an experimental group,and 23 children with HSCT from June-August 2023 as a control group.The experimental group was applied with the graded nursing program of exercise rehabilitation,and the control group was applied with the conventional nursing care.The comparison of cardiorespiratory fitness and adverse events between the 2 groups after 8 weeks of exercise intervention was conducted,and the adherence to the exercise intervention programme in the experimental group was recorded.Results The final constructed graded care program of exercise rehabilitation for children with HSCT included 6 primary indicators,20 secondary indicators,and 44 tertiary indicators.Finally,21 children in the experimental group and 23 children in the control group were included in the study.After the intervention,the 6 min walking distance of the experimental group increased compared with that of the control group,and the difference was statistically significant(P＜0.001).85.71％of children in the experimental group had good exercise compliance,and there was no adverse events in both groups.Conclusion The constructed graded nursing program of exercise rehabilitation for children with HSCT is scientific,reasonable,safe and feasible,which can improve the cardiorespiratory capacity of children with HSCT and provide the basis for their exercise rehabilitation.

Objective:To investigate the association of serum/body fluid heparin-binding protein (HBP) and blood lactate levels with disease severity and their impact on prognosis in intensive care unit (ICU) patients with sepsis.Methods:Clinical data from 100 sepsis patients admitted to Ma'anshan Shiqiye Hospital ICU (January 2023-September 2024) were retrospectively analyzed. According to Sepsis-3.0 criteria, patients were divided into: uncomplicated sepsis (general group, n=28), sepsis with organ failure/hypotension (severe group, n=61), and septic shock (shock group, n=11). Comparisons included serum/body fluid HBP, lactate, APACHE Ⅱ scores, and mortality across severity groups and laboratory parameters between survivors and non-survivors. Logistic regression was used to identify prognostic predictors. Non-normally distributed data were presented as M(Q1,Q3), comparison between groups were completed by Kruskal-Wallis H test and Mann-Whitney U tests. Spearman correlation was used to analyze relationships between biomarkers and APACHE Ⅱ scores. Categorical data were presented as n(%), and comparison between groups were completed by χ2 test or Fisher's exact tests. ROC curves was used to evaluate predictive value. Results:Shock group demonstrated significantly higher serum HBP [13.3 (12.6-16.4) μg/L], infection-site HBP [230.3 (226.3-241.1) μg/L], lactate [5.4 (4.9-5.6) mmol/L], and APACHE Ⅱ[22.0 (21.0-24.0)] than severe group [9.6 (8.9-10.5) μg/L; 208.9 (200.5-216.1) μg/L; 2.7 (2.6-2.8) mmol/L; 18.0 (17.0-19.0)] and general group [7.4 (6.3-8.1) μg/L; 190.6 (180.5-202.1) μg/L; 1.5 (1.4-1.7) mmol/L; 13.0 (12.0-14.0)] (all P<0.001). There was statistically significant difference in the mortality rate during hospita lization among three groups of patients ( χ2=30.49, P<0.001). Mortality was higher in shock group than severe group than general group [72.7% (8/11) vs. 11.5% (7/61) vs. 3.6% (1/28), all P<0.001]. Non-survivors exhibited elevated lactate [4.8 (2.7-5.5) vs. 2.6 (1.7-2.8) mmol/L, Z=-4.13, P=0.001], serum HBP [12.2 (9.2-13.3) vs. 9.3 (7.8-10.4) μg/L, Z=-3.12, P=0.002], and infection-site HBP [226.8 (209.9-237.6) vs. 203.6 (194.0-212.8) μg/L, Z=-4.32, P<0.001] vs. survivors. Serum HBP ( r=0.74), infection-site HBP ( r=0.64), and lactate ( r=0.86) were all positively correlated with APACHE Ⅱ (all P<0.001). After adjusting for age and APACHE Ⅱ, elevated serum HBP ( OR=3.743, 95% CI:1.834-7.640), infection-site HBP ( OR=3.540, 95% CI:1.932-6.486), and lactate ( OR=5.155, 95% CI:1.868-14.229) independently predicted mortality (all P<0.001). Combined biomarker detection showed superior predictive value (AUC=0.909) versus individual markers (serum HBP:0.747, infection-site HBP:0.842, lactate:0.827, all P<0.001). Conclusion:Elevated blood lactate and serum/infection-site HBP levels correlate with sepsis severity and independently predict mortality. The biomarker combination provides optimal prognostic stratification.

Objective To investigate the expression of serum microRNA-204-5p(miR-204-5p)in patients with sudden deafness(SD)and its relationship with cochlear function and hearing prognosis.Methods A to-tal of 113 SD patients admitted to this hospital from October 2020 to October 2023 were selected as the case group.According to the hearing prognosis of SD patients,they were divided into a poor prognosis group(n=43)and a good prognosis group(n=70).Another 95 healthy people who underwent the physical examination were selected as the control group.Real-time fluorescent quantitative PCR and enzyme-linked immunosorbent assay were used to detect serum levels of miR-204-5p and endothelin-1(ET-1),and the relationship between them and cochlear function was analyzed.Automatic hemorheology instrument was used to detect the hemo-dynamic parameters.Multivariate Logistic regression was used to analyze the influencing factors of hearing prognosis in SD patients.Receiver operating characteristic(ROC)curve was used to analyze the predictive val-ue of serum miR-204-5p in hearing prognosis of SD patients.Results The serum levels of miR-204-5p and ET-1 and hemodynamic parameters including plasma viscosity(PV),low-shear viscosity(LSV)and whole blood high-shear viscosity(HSV)in the case group were significantly higher than those in the control group(P<0.05).The incidence of cochlear dysfunction in the miR-204-5p high expression group was higher than that in the miR-204-5p low expression group(P<0.05).The levels of serum miR-204-5p,ET-1,PTA,HSV,LSV and PV in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).HSV,LSV,PV,miR-204-5p and ET-1 were related factors affecting the hearing prognosis of SD patients(P<0.05).The area under the curve of serum miR-204-5p,ET-1 combined with hemodynamic pa-rameters to predict the hearing prognosis of SD patients was 0.976.It was better than that of each individual diagnosis(Zfive combination-HSV=3.464,Zfive combination-LSV=3.014,Zfive combination-PV=3.741,Zfive combination-miR-204-5p=3.476,Zfive combination-ET-1=2.829,P=0.001,0.003,<0.001,0.001,0.005).The sensitivity and specificity of combined prediction were 95.35%and 88.57%,respectively.Conclusion Serum miR-204-5p level is significantly in-creased in SD patients,which is closely related to cochlear function and hearing prognosis.Serum miR-204-5p and ET-1 levels combined with hemodynamic indicators have higher predictive efficiency for hearing prognosis in SD patients.

Objective:To explore the application effect of comfort-based light sedation strategy nursing model in early rehabilitation exercises for critically ill patients after gastrointestinal surgery, aiming to provide a reference for the recovery of patients after gastrointestinal surgery.Methods:A randomized controlled trial was conducted using purposive sampling to select 110 critically ill patients who underwent gastrointestinal surgery from July 2022 to December 2023 in the Department of Critical Care Medicine of Shantou Central Hospital. Patients were randomly assigned into the control group and the observation group, with 55 cases in each group. The control group received routine sedation care, while the observation group adopted a comfort-based light sedation strategy nursing model. The NRS (Digital Rating Scale for Pain), RASS (Rationalizing Self-Assessment Scale), SAS (Self-Rating Anxiety Scale), analgesic and sedative drug usage, postoperative bowel sounds, flatus, and defecation onset time, ICU length of stay, delirium incidence, postoperative 24-hour MRC muscle strength score, and discharge Modified Barthel Index (MBI) scores were compared between the two groups at 8 hours, 24 hours, 48 hours, 72 hours, and 96 hours postoperatively.Results:During the study, 5 cases dropped out from both the observation and control groups, leaving 50 cases each complete. The control group consisted of 32 males and 18 females, with an average age of (66.94 ± 14.39) years; the observation group consisted of 34 males and 16 females, with an average age of (68.01 ± 14.76) years. At 8, 24, 48, 72, 96 hours postoperatively, the NRS scores for the observation group were (3.11 ± 0.58), (3.14 ± 0.53), (3.09 ± 0.56), (2.97 ± 0.50), and (2.48 ± 0.45), respectively, were all lower than those of the control group (3.55 ± 0.61), (3.46 ± 0.59), (3.42 ± 0.62), (3.38 ± 0.54), (2.87 ± 0.53), with statistically significant differences ( t values were 2.80 - 3.97, all P<0.05). The RASS scores at postoperative 8, 24, 48, 72, 96 hours were (- 1.42 ± 0.43), (- 1.41 ± 0.42), (- 1.39 ± 0.44), (- 1.36 ± 0.41), (- 1.32 ± 0.40) respectively, compared to the control group (- 1.85 ± 0.47), (- 1.78 ± 0.44), (- 1.81 ± 0.50), (- 1.80 ± 0.48), (- 1.68 ± 0.45), with statistically significant differences ( t values were 4.23 - 4.93, all P<0.05). The SAS scores at postoperative 48, 72, 96 hours were (49.68 ± 4.55), (48.69 ± 4.41), (46.71 ± 4.33) respectively, compared to the control group (53.75 ± 4.76), (53.13 ± 4.69), (52.84 ± 4.51), with statistically significant differences ( t = 4.37, 4.89, 6.93, all P<0.05); the propofol dosage in the observation group (3 228.52 ± 587.78) mg and the dexmedetomidine dosage (1 205.58 ± 311.46) μg were all lower than those of the control group (4 056.77 ± 638.04) mg and (1 650.77 ± 432.69) μg, with statistically significant differences ( t = 6.75, 5.92, both P<0.05). The start time of bowel sounds in the observation group was (18.63 ± 5.96) hours, the start time of flatus was (1.42 ± 0.57) days, and the start time of defecation was (2.02 ± 1.25) days. The ICU hospitalization duration of the observation group (5.54 ± 1.51) days was shorter than that of the control group (7.36 ± 1.89) days, with differences being statistically significant ( t values were 2.71 - 5.32, all P<0.05). The postoperative delirium incidence rate of the observation group was 8.00% (4/50) lower than that of the control group 24.00% (12/50), with differences being statistically significant ( χ2 = 4.76, P<0.05). The postoperative 24-hour MRC muscle strength score (5.34 ± 0.58) and the discharge MBI score (77.56 ± 11.34) in the observation group were both significantly higher than those of the control group (4.79 ± 0.65) and (68.25 ± 10.47), respectively ( t = 4.46, 4.27, both P<0.05). Conclusions:The comfort-oriented light sedation strategy nursing model can improve the postoperative sedation and analgesia effects for ICU gastrointestinal surgery patients, promote gastrointestinal function recovery, shorten ICU hospital stay, reduce delirium incidence, and accelerate patient postoperative recovery.

Objectives To construct frailty risk prediction models based on logistic regression anal-ysis,decision tree and random forest algorithm in elderly patients with heart failure(HF),and to compare the predictive performance of three models.Methods A total of 426 elderly HF patients hospitalized in the Affiliated Hospital of Nantong University from September 2022 to October 2023 were selected using convenience sampling.Based on the results of frailty assessment,194 of them were classified into the frail group and the other 232 into the non-frail group.The 426 patients were divided into training(299 casses)and testing sets(127 cases)in a 7∶3 ratio.Three prediction models were then constructed in the training set,while the test set was used to validate the results.Area under curve and confusion matrix were used to measure performance of the mod-els.The optimal model was then selected by evaluating the performance on the testing set.Results The area under curve value of the logistic regression model,decision tree model and random forest model in the testing set was 0.898,0.825 and 0.903,with a classification accuracy of 84.25％,77.95％and 83.46％,a sensitivity of 82.76％,68.97％and 82.76％,a specificity of 85.51％,85.51％and 84.06％,a positive predictive value of 82.76％,80.00％and 81.36％,and a negative predictive value of 85.51％,76.62％and 85.29％,respectively.The factors that ultimately affecting frailty in elderly HF patients were age,left atrial diameter,depression,albumin,physical activity level and social support.Conclusion Among the three prediction models,the logistic regression model demonstrates best predictive performance for frailty risk in elderly HF patients than the decision tree and random forest models.

Objective:To investigate the overall drug resistance, drug resistance trend and distribution of drug resistance mutation sites in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients with antiviral therapy failure in Yunnan Province.Methods:The demographic data and genotype drug resistance of HIV/AIDS population with antiviral therapy failure in Yunnan Province from January 2021 to December 2023 were collected and analyzed by cross-sectional investigation. Statistical analyses were performed using chi-square test.Results:Among 15 159 HIV/AIDS patients, 12 215 cases tested positive by amplification. The circulating recombinant form (CRF) 08_BC was the predominant genetic subtype, accounting for 54.97%(6 714/12 215), followed by CRF01_AE (16.14%(1 972/12 215)) and CRF07_BC (14.48% (1 769/12 215)). When the viral load was ≥200 to <1 000 copies/mL, the incidence of drug resistance was 21.48%(99/461). When it was ≥1 000 to <10 000 copies/mL, the incidence was 51.29%(2 867/5 590). When it was ≥10 000 to <100 000 copies/mL, the incidence was 69.39% (3 979/5 734). When it was ≥100 000 copies/mL, the incidence was 81.86%(352/430). A total of 7 297 drug resistant cases were detected, with a drug resistance rate of 59.74% (7 297/12 215), thus the estimated drug resistance incidence rate among the antiviral treated population in Yunnan Province was 2.00% (7 297/364 238). From 2021 to 2023, the annual drug resistance rates among patients were 60.71%(2 554/4 207), 60.28%(1 671/2 772), and 58.67% (3 072/5 236), respectively, with no statistically significant difference ( χ2=4.47, P=0.107). Among the population with antiviral therapy failure, the drug resistance rates of non-nucleoside reverse transcriptase inhibitor (NNRTI), nucleoside reverse transcriptase inhibitor (NRTI), and protease inhibitor (PI) were 93.70%(6 837/7 297), 44.10%(3 218/7 297) and 5.15%(376/7 297), respectively. The mutation sites with the highest frequencies among the three classes of drugs including NRTI, NNRTI and PI were M184V/I (46.13%(2 123/4 602)), K103N/S (37.14%(2 648/7 129)), L33F (15.50%(82/529)) and M46I/L (15.50%(82/529)), respectively. Analysis of the degree of drug resistance showed that among NNRTI drugs, nevirapine (49.01%(5 987/12 215)) and efavirenz (48.00%(5 863/12 215)) had the highest drug resistance rates, followed by emtricitabine (23.59%(2 882/12 215)) and lamivudine (23.58%(2 881/12 215)) among NRTI drugs. Conclusions:Among HIV/AIDS patients with antiviral therapy failure in Yunnan Province from 2021 to 2023, CRF08_BC is the main genetic subtype. The drug resistance rate of patients increases with the increase of HIV-1 viral load. There is no significant change in the drug resistance rate from 2021 to 2023. NNRTI has the highest drug resistance rate, followed by NRTI, and PI has the lowest. The main mutation sites are M184V/I for NRTI, K103N/S for NNRTI, and M46I/L and L33F for PI. The drug resistance rates of nevirapine, efavirenz, emtricitabine and lamivudine are relatively high.

Objective To explore the perfusion distribution of vertebral arteries(VA)in healthy adults,and to observe the impact of VA diameter on perfusion distribution based on territorial arterial spin labeling(t-ASL)technique.Methods A total of 228 healthy adult volunteers were prospectively recruited.t-ASL imaging was utilized to analyze VA perfusion patterns in supratentorial region.Bilateral VA diameters,absolute inter-side VA diameter differences,as well as perfusion volumes(PV)supplied by each VA to supratentorial,cerebellar and their combined were recorded.Pearson correlation analysis was performed to analyze the correlations of VA diameters with PVsupratentorial,PVcerebellar and PVsupratentorial+cerebellar.Results Five patterns of distinct perfusion distribution were identified in supratentorial region,leading to participant stratification into 5 groups.Significant differences of absolute inter-side VA diameter differences was found among groups(P＜0.001).The mean bilateral VA diameter,PVsupratentorial,PVcerebellar and PVsupratentorial+cerebellar was(1.94±0.49)mm,(91.77±49.34)cm3,(74.72±27.68)cm3 and(166.49±59.53)cm3,respectively.VA diameter showed low-moderate positive correlations with PVsupratentorial,PVcerebellar and PVsupratentorial+cerebellar(r=0.483,0.179,0.484,all P＜0.001).Conclusion Perfusion imaging of t-ASL could visualize various perfusion distribution forms of VA in supratentorial region.Diameter of VA had certain impact on both spatial distribution characteristics and quantitative perfusion volumes.
