Objective:To analyze the application effect of condition scale in nursing management of children bronchial asthma in acute attack stage.Methods:A total of 136 children with acute attack of bronchial asthma admitted to Shanxi Children's Hospital from January 2020 to December 2021 were selected by convenience sampling method, and randomly divided into observation group and control group according to random number table method, 68 cases in each group. Children in the observation group received graded nursing intervention based on disease scale, while children in the control group received routine nursing intervention. The first second forced expiratory volume (FEV 1), forced vital capacity (FVC), ratio of FEV l/FVC, peak expiratory flow rate (PEF), medical intervention frequency, the number of ICU transfer and length of stay were compared between the two groups. Results:The results of repeated measurement ANOVA showed that there were intergroup, time and interaction effects on the levels of FEV 1, FVC, FEV 1/FVC and PEF in the two groups, and the differences were statistically significant ( P<0.05). The frequency of medical intervention in observation group was less than that in control group, and the length of hospitalization was shorter, with statistical significance ( P<0.05). There was no significant difference in ICU patients transferred between the two groups ( P>0.05) . Conclusions:Application of Condition Scale in nursing management of children with acute attack of bronchial asthma can improve the lung function of children with acute attack bronchial asthma more effectively, reduce the frequency of medical intervention, shorten the length of hospital stay, and significantly improve the nursing effect.

AIM: To analyze the influencing factors of postoperative dry eye complication after corneal transplantation and to build a nomogram prediction model.METHODS: Clinical data were collected on 117 patients who underwent corneal transplantation at our hospital from March 2021 to February 2023. They were divided into dry eye group(n=96)and non-dry eye group(n=21)according to whether there was a postoperative dry eye. The risk factors of postoperative complication of dry eye after corneal transplantation were analyzed, the nomogram prediction model for predicting postoperative complication of dry eye after corneal transplantation was constructed, and the internal validation of the model and the prediction efficacy were assessed by calibration curves and decision curves, respectively.RESULTS: Comorbid diabetes mellitus, comorbid sleep disorders, comorbid meibomian gland dysfunction, chronic eye drop abuse, chronic corneal contact lens wear, interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α)were the risk factors for the complication of dry eye after corneal transplantation(P<0.05). The nomogram model predicted a C-index of 0.890(95% CI 0.877-0.903). The nomogram model had a threshold >0.07, and the nomogram model provided higher net clinical benefit than the single index in all cases.CONCLUSION: The nomogram model built in this study based on the factors affecting the complication of dry eye after corneal transplantation has a good predictive value for the complication of dry eye after corneal transplantation.

Objective:To analyze the risk factors and prognosis for early acute kidney injury (AKI) after orthotopic liver transplantation (OLT).Methods:The retrospective study was conduc-ted. The clinicopathological data of 340 pairs of donor and recipients undergoing OLT in The First Affiliated Hospital of Nanjing Medical University from January 2016 to January 2020 were collected. There were 262 males and 78 females of donors. There were 268 males and 72 females of recipients, aged (51±11)years. Of 340 recipients, 217 cases without postoperative early AKI were divided into the non-AKI group and 123 cases with postoperative early AKI were divided into the AKI group. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distri-bution were represented as M( IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the non-parameter test. Multivariate analysis was conducted using the binary Logistic regre-ssion model with forward method. The nomogram predictive model was constructed using the R software with its RMS package (R3.6.1). The efficacy of the predictive model was validated using the area under curve (AUC) of the receiver operating characteristic (ROC) curve, and internal validation of the predictive model was performed using the Bootstrap method. The Kaplan-Meier method was used to draw survival curves, and Log-rank test was used for survival analysis. Results:(1) Com-parison of preoperative clinical characteristics between donors and recipients of the non-AKI group and the AKI group. There was a significant difference in overweight of donors between the non-AKI group and the AKI group ( P<0.05). There were significant differences in preoperative hypertension, viral hepatitis, pathological types, international normalized ratio, fibrinogen levels, platelet (PLT), hemoglobin, and anemia of recipients between the non-AKI group and the AKI group ( P<0.05). (2) Comparison of surgical situations between recipients of the non-AKI group and the AKI group. There were significant differences in intraoperative urine output, volume of intraoperative blood loss, peak serum potassium after reperfusion, massive transfusion, plasma infusion, cryoprecipitate infusion, and aminocaproic acid use of recipients between the non-AKI group and the AKI group ( P<0.05). (3) Influencing factors for postoperative early AKI and construction and evaluation of the nomogram predictive model for postoperative early AKI. Results of multivariate analysis showed that donors of overweight, recipients of preoperative hypertension, recipients of non-viral hepatitis, recipients of preoperative severe PLT reduction, recipients of less intraoperative urine output, recipients of severe post-reperfusion hypotension, recipients of high peak serum potassium after reperfusion, recipients with intraoperative plasma infusion were independent risk factors for postoperative early AKI ( odds ratio=1.982, 3.365, 0.519, 3.615, 0.169, 2.480, 1.500, 1.001, 95% confidence interval as 1.160-3.388, 1.649-6.865, 0.293-0.917, 1.358-9.621, 0.061-0.464, 1.246-4.934, 1.003-2.243, 1.000-1.001, P<0.05). The nomogram predictive model for postoperative early AKI was constructed based on the results of multivariate analysis. Results of ROC curve showed the AUC was 0.769 (95% confidence interval as 0.717-0.820). Results of the calibration curve showed that the predictive results of nomogram predictive model fitted well with the actual situation, with a mean absolute error of 0.016. (4) Comparison of prognosis between recipients of the non-AKI group and the AKI group. There were significant differences in postopera-tive peak creatinine, peak brain natriuretic peptide, duration of intensive care unit stay, mechanical ventilation time, re-intubation of recipients between the non-AKI group and the AKI group ( Z=-4.836, -5.652, -5.861, -6.533, χ2=14.676, P<0.05). All 340 recipients were followed up. For recipients of hepatocellular carcinoma, the 6-month survival rates after surgery were 87.8% and 75.6% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=4.010, P<0.05), and the overall survival rates were 46.7% and 56.1% of the non-AKI group and the AKI group, respectively, showing no significant difference between them ( χ2=0.047, P>0.05). For recipients of benign liver disease, the 6-month survival rates after surgery were 89.8% and 78.0% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=6.401, P<0.05), and the overall survival rates were 81.4% and 68.0% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=4.452, P<0.05). Conclusions:Donors of overweight, recipients of preoperative hypertension, recipients of non-viral hepatitis, recipients of preoperative severe PLT reduction, reci-pients of less intraoperative urine output, recipients of severe post-reperfusion hypotension, recipi-ents of high peak serum potassium after reperfusion, recipients with intraoperative plasma transfu-sion were independent risk factors for postoperative early AKI. Nomogram predictive model has well clinical application value. For recipients of benign liver disease, the 6-month survival rate after surgery and overall survival rate of recipients in the non-AKI group are superior to those of the AKI group.

Objective:To investigate the effect of dexmedetomidine on the intraoperative and early postoperative complications of patients undergoing orthotopic liver transplantation.Methods:This is a retrospective cohort study. The clinical data of 399 patients who underwent orthotopic liver transplantation at the First Affiliated Hospital of Nanjing Medical University from January 2016 to September 2020 were retrospectively collected. There were 319 males and 80 females, aged (50.9±10.2) years (range: 10 to 73 years). These patients were divided into the control group (369 cases) and the dexmedetomidine group (30 cases) according to whether dexmedetomidine was continuously pumped intravenously during the operation until the operation ended. The 1∶2 propensity score matching was used to match the preoperative and intraoperative conditions of the two groups of patients, and the caliper width was 0.2. Outcome indicators included intraoperative postreperfusion syndrome, acute kidney injury and pulmonary complications within 7 days after surgery, length of hospital stay, time of stay in ICU, duration of assisted mechanical ventilation, rate of reintubation, 6-month and 1-year survival and recurrence-free survival rate after surgery. The independent sample t test, χ2 test, Mann-Whitney U test or Fisher exact test was used to statistically analyze the data of the two groups of patients, respectively. Survival curves of overall survival and disease-free-survival were plotted by Kaplan-Meier method, and the survival rate and recurrence-free survival rate were compared by Log-rank test. Results:A total of 78 patients were included after propensity score matching, including 26 in the dexmedetomidine group and 52 in the control group. The incidence of acute kidney injury in the dexmedetomidine group within 7 days after surgery was 0 (0/26), significantly lower than that of the control group (21.2%,11/52)(corrected χ2=4.776, P=0.029). There were no significant differences in the incidence of intraoperative postreperfusion syndrome and pulmonary complications within 7 days after surgery, length of hospital stay, ICU time, the duration of assisted mechanical ventilation, rate of reintubation, 6-month and 1-year survival, and recurrence-free survival rate after surgery between the two groups (all P>0.05). Conclusion:Continuous infusion of dexmedetomidine via intravenous pump during operation may be beneficial in reducing the incidence of acute kidney injury within 7 days after orthotopic liver transplantation.

Objective:To investigate the distribution and antimicrobial resistance profile of clinical bacteria isolated from blood culture in China.Methods:The clinical bacterial strains isolated from blood culture from member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS) were collected during January 2018 to December 2019. Antibiotic susceptibility tests were conducted with agar dilution or broth dilution methods recommended by US Clinical and Laboratory Standards Institute (CLSI). WHONET 5.6 was used to analyze data.Results:During the study period, 14 778 bacterial strains were collected from 50 hospitals, of which 4 117 (27.9%) were Gram-positive bacteria and 10 661(72.1%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (37.2%), Klebsiella pneumoniae (17.0%), Staphylococcus aureus (9.7%), coagulase-negative Staphylococci (8.7%), Pseudomonas aeruginosa (3.7%), Enterococcus faecium (3.4%), Acinetobacter baumannii(3.4%), Enterobacter cloacae (2.9%), Streptococci(2.8%) and Enterococcus faecalis (2.3%). The the prevalence of methicillin-resistant S. aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus were 27.4% (394/1 438) and 70.4% (905/1 285), respectively. No glycopeptide-resistant Staphylococcus was detected. More than 95% of S. aureus were sensitive to amikacin, rifampicin and SMZco. The resistance rate of E. faecium to vancomycin was 0.4% (2/504), and no vancomycin-resistant E. faecalis was detected. The ESBLs-producing rates in no carbapenem-resistance E. coli, carbapenem sensitive K. pneumoniae and Proteus were 50.4% (2 731/5 415), 24.6% (493/2001) and 35.2% (31/88), respectively. The prevalence of carbapenem-resistance in E. coli and K. pneumoniae were 1.5% (85/5 500), 20.6% (518/2 519), respectively. 8.3% (27/325) of carbapenem-resistance K. pneumoniae was resistant to ceftazidime/avibactam combination. The resistance rates of A. baumannii to polymyxin and tigecycline were 2.8% (14/501) and 3.4% (17/501) respectively, and that of P. aeruginosa to carbapenem were 18.9% (103/546). Conclusions:The surveillance results from 2018 to 2019 showed that the main pathogens of bloodstream infection in China were gram-negative bacteria, while E. coli was the most common pathogen, and ESBLs-producing strains were in majority; the MRSA incidence is getting lower in China; carbapenem-resistant E. coli keeps at a low level, while carbapenem-resistant K. pneumoniae is on the rise obviously.
