Objective To analyze the application value of uterine artery flow and cerebral placental rate(CPR)in diagnosing fetal growth restriction(FGR).Methods A total of 114 pregnant women with clinically diagnosed late-onset FGR who were hospitalized in Jiangxi Maternal and Child Health Hospital from January 2021 to June 2022 were assigned to study group,and 122 pregnant women with normal intrauterine development were assigned to control group.The blood flow parameters of uterine artery(UtA),umbilical artery(UA)and middle cerebral artery(MCA)in two groups were determined by ultrasound,and CPR in two groups was calculated.The blood flow difference and pregnancy outcome of two groups were compared.Receiver operating characteristic(ROC)curve was used to analyze the application value of UtA and CPR alone and combined in the clinical diagnosis of FGR.Results The UtA resistance index(RI)of pregnant women in study group was higher than that of control group,the fetal UA blood flow parameter was higher than that of control group,the MCA blood flow parameter and the CPR value were both lower than those of control group,the differences were statistically significant(P<0.05).The birth weight and 1min Apgar score of study group were lower than those of control group(P<0.001).In addition,the incidence of emergency cesarean section operation,premature delivery and neonates transferred to neonatal intensive care unit(NICU)due to various complications in study group were significantly higher than those in control group(P<0.05).ROC curve showed that in predicting FGR,the area under the curve(AUC)of UtA-RI was 0.82(95%CI:0.77-0.88).The predictive efficiency of CPR was 0.75(95%CI:0.69-0.81).The combination of UtA-RI and CPR parameters had the highest efficiency in predicting FGR,with an AUC of 0.92(95%CI:0.89-0.95).Conclusion CPR combined with UtA-RI monitoring has clinical application value for early detection of FGR,guiding intervention,and improving adverse perinatal outcomes.

The five core indicators(the case mix index, the proportion of level-4 surgery, the proportion of technical service income in medical income, the proportion of personnel expenditure in business expenditure, and the proportion of fixed part in personnel salary) and target values determined by the pilot goal of high-quality development of high-level public hospitals jointly built by National Health Commission and Provincial Government had become the core indicators for evaluating the quality and efficiency of public hospital development. The authors proposed the optimization and improvement measures for the five core indicators one by one from the internal reform and innovation in hospitals, as well as the synergetic development and governance of " insurance-medical-medicine linkage", combined with the current situation of a pilot hospital. The authors also proposed the starting points and driving force for promoting the high-quality development of public hospitals through the synergetic development and governance of " insurance-medical-medicine linkage", including implementing government investment responsibilities, streamlining the price evaluation of medical services, deepening the reform of medical insurance payment, accelerating the expansion of drug and consumable procurement, and promoting the application of advanced technologies and products, in order to provide reference for the in-depth promotion of high-quality development of public hospitals.

Objective:To explore the current situation of fear of progression among parents of school-age children with asthma, and to analyze the latent profile categories and influencing factors, so as to provide the reference for the formulation of prevention and intervention.Methods:Using convenient sampling method, school-age children with asthma and their parents treated in the Affiliated Children's Hospital of Xiangya School of Medicine, Central South University from March to August 2023 were selected as the study objects. The General Data Questionnaire, Parent Fear of Progression Scale, Childhood Asthma Control Test, and Social Support Rating Scale were used to investigate school-age children with asthma and their parents. Latent profile analysis was performed on the fear of disease progression among parents of school-age children with asthma, and χ2 test and binary Logistic regression were used to explore the influencing factors. Results:A total of 210 parents of the children were included with 51 fathers and 159 mothers.The age distribution was 20-30 years old with 42 parents, 31-40 years old with 112 parents, 41-50 years old with 56 parents. In 210 children with asthma, there were 123 males and 87 females, with 141 cases aged<10 years old and 69 cases aged ≥10 years old. The fear of progression among parents of school-age children with asthma could be divided into two potential profile categories: "psychological dysfunction group (46.7%, 98/210)" and "psychological health good group (53.3%, 112/210)". The results of binary Logistic regression analysis showed that asthma family history, combined allergic rhinitis, child-parent relationship, marital status, asthma symptom control level, and social support level were the influencing factors of fear of progression among parents of school-age children with asthma( OR values were 0.925-10.010, all P<0.05). Conclusions:The fear of progression among parents of school-age children with asthma is at a moderate level, and there are obvious different classification characteristics. In the future, targeted and precise prevention and intervention should be implemented according to the category characteristics of fear of progression among parents of school-age children with asthma.

Objective To develop a pulmonary rehabilitation training system based on scenario simulation for children with bronchiolitis obliterans,and to explore its application effect.Methods A pulmonary rehabilitation training program for children with bronchiolitis obliterans was constructed,and on the basis of this program,a pul-monary rehabilitation training system based on scenario simulation was developed for children with bronchiolitis obliterans,with real-time monitoring of relevant data.44 children with bronchiolitis obliterans who were hospitalized in the Department of Respiratory Medicine of a tertiary A children's specialized hospital in Hunan Province from January to December 2022 were selected by convenience sampling method,and the subjects were divided into an experimental group and a control group with 22 cases in each group.The experimental group adopted a pulmonary rehabilitation training program based on scenario simulation,and the control group implemented pulmonary rehabili-tation through nurse demonstration and guidance.At pre-intervention,4 weeks,and 12 weeks of intervention,the 2 groups were compared in terms of clinical symptom severity,pulmonary function,adherence to pulmonary rehabilita-tion,and the occurrence of pulmonary rehabilitation-related adverse events.Results There were no shedding cases in the experimental group and a case in the control group,and 22 cases were finally included in the experimental group and 21 cases in the control group.The results of repeated measures ANOVA showed that the comparison of clinical symptom severity and pulmonary function between the 2 groups at different time points was statistically sig-nificant in terms of time,between groups and interaction(P＜0.05).Simple effect analysis showed that after 4 and 12 weeks of intervention,the severity of clinical symptoms in the experimental group was lighter than that in the control group,and the difference was statistically significant(P＜0.001).At 12 weeks of intervention,pulmonary func-tion indexes,such as exertional expiratory volume in the first second,exertional lung volume,and maximum expiratory flow rate,were higher in the experimental group than those in the control group,and the difference was statistically significant(P＜0.001).At 4 and 12 weeks of intervention,the compliance of pulmonary rehabilitation in the experi-mental group was higher than that of the control group,and the difference was statistically significant(P＜0.05).At 12 weeks of intervention,the occurrence of adverse events related to pulmonary rehabilitation in the experimental group was less than that in the control group,and the difference was statistically significant(P=0.026).Conclusion The use of a scenario simulation-based pulmonary rehabilitation training system for children with bronchiolitis obliterans can effectively alleviate the clinical symptoms of children,improve their pulmonary function,increase compliance,and reduce the occurrence of pulmonary rehabilitation-related adverse events.

Objective:To explore application effect of early respiratory training schemes based on 4E mode (Engage, Educate, Execute, Evaluate) in children with bronchiolitis obliterans (BO) and provide evidence for the clinical implementation of early respiratory rehabilitation in children with BO.Methods:This was a quasi-experimental study. The children with BO who were admitted to 2 wards of the Department of Respiratory Medicine of Hunan Children's Hospital from January 1 to December 31, 2021 were selected as the research objects. They were randomly divided into the control group and the experimental group, with 23 cases in each group. The control group received routine treatment, nursing and rehabilitation guidance. The experimental group established a multidisciplinary team based on the control group, and used the early respiratory training program based on the 4E model to implement intervention. The clinical symptom severity scale was used to evaluate the improvement of the clinical symptoms of the children within 24 hours of being diagnosed as BO, the day of discharge, and 1 and 3 months after discharge for re-examination, and the hospitalization time of the children and the incidence of adverse events related to respiratory training were counted by using medical records and questionnaires.Results:The clinical symptom severity scores of the experimental group within 24 hours of admission diagnosis and the day of discharge were (20.00 ± 2.51) and (11.30 ± 2.46)points respectively, while those of the control group were (20.57 ± 2.21) and (11.70 ± 2.42) points respectively, with no statistically significant difference ( t=0.81, 0.54, both P>0.05). The clinical symptom severity scores of the experimental group were(10.52 ± 2.31) and (8.55 ± 1.06) points, lower than (12.32 ± 1.39) and (12.45 ± 2.19) points of the control group when they returned to the hospital for re-examination 1 and 3 months after discharge, with a statistically significant difference ( t=3.14, 7.25, both P<0.05). The experimental group was hospitalized for (11.78 ± 1.17) days, which was showter than (13.74 ± 1.63) days in the control group, with a statistically significant difference ( t=4.68, P<0.05). No respiratory training-related adverse events occurred in both groups of children during hospitalization. During home respiratory training after discharge, 1 and 2 respiratory training-related adverse events occurred in the experimental group 1 and 3 months after discharge, respectively, compared with 6 and 9 in the control group. The difference was statistically significant ( χ2=4.64, 5.94, both P<0.05). Conclusions:Early respiratory training solutions based on the 4E mode can improve the clinical symptoms of BO children, shorten the hospitalization time, reduce the number of adverse events related to respiratory training, and promote the recovery of children.

Based on the five core indicators (the case mix index, the proportion of level-4 surgery, the proportion of technical service income in medical income, the proportion of personnel expenditure in business expenditure, and the proportion of fixed part in personnel salary), the authors discussed the guiding significance of " paying attention to the medical level, strengthening the functional orientation, reflecting the technical value, highlighting people-orientation, and ensuring sustainable development" in the high-quality development of public hospitals. In combination with the current situation of a pilot hospital of high-quality development with the corporate supports of National Health Commission and Province Government, the authors explained the common bottlenecks of public hospitals, such as inaccurate functional positioning, weak innovation ability, poor finance structure, poor salary system and insufficient attention to talents. In the last, the authors pointed out that high-quality development was the development of deepening reform, innovation driven, structural optimization, talent oriented, people-oriented and under the leadership of the Communist Party of China, and put forward targeted implementation paths to provide reference for the pilot work.

Objective:To analyze the internal conditions and external environment of high-quality development of high-level public hospitals and establish a high-quality development strategy model, for reference of public hospitals to formulate and implement high-quality development strategies.Methods:The case hospital was a pilot in high-quality development of high-level public hospitals. SWOT method was used to analyze the influencing factors, AHP analytic hierarchy process was used to compare the importance of each influencing factor, and then the four-quadrant coordinate system method was used to establish a high-quality development strategy model.Results:The total strength(S), the total weaknesses(W), the total opportunity(O), and the total threat(T)were 0.095, 0.063, 0.065 and 0.024 respectively, reflecting that the strength of internal conditions was greater than the weaknesses, and the opportunities of external environment were greater than the threats. In the four-quadrants, the growth strategy model had the largest triangle area(0.003), and the strategic quadrilateral center of gravity was located in the opportunity area of the growth strategy.Conclusions:High-level public hospitals as represented by the case hospital had entered a period of important strategic opportunities, which the external opportunities were greater than its own strength. These hospitals were recommended to fully leverage the external opportunities, adopt a positive growth oriented(SO)strategy, formulate a development strategy with their own characteristics, promote the interaction of internal conditions and external environment to form new momentum, hence achieving high-quality development.

Objective: To determine whether T1 mapping could monitor the dynamic changes of injury in myocardial infarction (MI) and be histologically validated. Materials and Methods: In 22 pigs, MI was induced by ligating the left anterior descending artery and they underwent serial cardiovascular magnetic resonance examinations with modified Look-Locker inversion T1 mapping and extracellular volume (ECV) computation in acute (within 24 hours, n = 22), subacute (7 days, n = 13), and chronic (3 months, n = 7) phases of MI. Masson’s trichrome staining was performed for histological ECV calculation. Myocardial native T1 and ECV were obtained by region of interest measurement in infarcted, peri-infarct, and remote myocardium. Results: Native T1 and ECV in peri-infarct myocardium differed from remote myocardium in acute (1181 ± 62 ms vs. 1113 ± 64 ms, p = 0.002; 24 ± 4% vs. 19 ± 4%, p = 0.031) and subacute phases (1264 ± 41 ms vs. 1171 ± 56 ms, p < 0.001; 27 ± 4% vs. 22 ± 2%, p = 0.009) but not in chronic phase (1157 ± 57 ms vs. 1120 ± 54 ms, p = 0.934; 23 ± 2% vs. 20 ± 1%, p = 0.109). From acute to chronic MI, infarcted native T1 peaked in subacute phase (1275 ± 63 ms vs. 1637 ± 123 ms vs. 1471 ± 98 ms, p < 0.001), while ECV progressively increased with time (35 ± 7% vs. 46 ± 6% vs. 52 ± 4%,p < 0.001). Native T1 correlated well with histological findings (R2 = 0.65 to 0.89, all p < 0.001) so did ECV (R2 = 0.73 to 0.94, all p < 0.001). Conclusion T1 mapping allows the quantitative assessment of injury in MI and the noninvasive monitoring of tissue injury evolution, which correlates well with histological findings.
