Objective:To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Weinan City, Shaanxi Province, and study the predictive effect of the seasonal autoregressive integrated moving average (SARIMA) model.Methods:Relevant information on HFRS cases reported by the China Disease Prevention and Control Information System from January 2010 to August 2024 in Weinan City, as well as the epidemiological investigation data on clinical diagnosis and confirmed HFRS cases in Weinan City were collected. Epidemiological characteristics of HFRS were analyzed by descriptive epidemiological methods. At the same time, a SARIMA model was constructed based on the monthly incidence of HFRS from 2010 to 2023, the incidence of HFRS from January to August 2024 was used to test the simulation prediction effect, and the optimal model was used to predict the incidence of HFRS from September to December 2024.Results:A total of 4 373 HFRS cases were reported in Weinan City from 2010 to 2023, with an average annual incidence of 6.39/100 000. The incidence rate showed a cyclical fluctuation trend, reaching two peaks in 2012 (10.25/100 000) and 2021 (12.26/100 000), respectively. The incidence of HFRS presented a seasonal bimodal distribution, with the peak predominantly in autumn and winter (from October to January of the following year), accounting for 67.83% (2 966/4 373), and the peak in spring and summer (form May to July) accounting for 17.27% (755/4 373). HFRS cases were reported in all counties (cities and districts) of Weinan City, and the top 3 annual incidence rates were Huazhou District (17.84/100 000), Linwei District (16.10/100 000) and Huayin City (9.15/100 000). The age of onset was mainly concentrated in the age group of 15 - 59 years old, accounting for 68.31% (2 987/4 373). The male to female ratio was 2.96∶1.00 (3 268∶1 105). The main occupation was farmers, accounting for 82.07% (3 589/4 373). SARIMA (1, 0, 1) (2, 1, 1) 12 model was the optimal model for short-term prediction of HFRS incidence rate in Weinan City, and the residual difference was listed as white noise ( Q = 7.45, P = 0.878), the model could be used for disease prediction. The model was used to predict the incidence of HFRS from September to December 2024, and the predicted values of each month were 0.17/100 000, 0.59/100 000, 1.85/100 000 and 1.61/100 000, respectively. Conclusions:The epidemic range of HFRS in Weinan City is wide, and the incidence has obvious seasonality. The population are mainly males, young and middle-aged adults and farmers. The SARIMA (1, 0, 1) (2, 1, 1) 12 model constructed can be used for predicting the short-term incidence trend of HFRS in Weinan City.

Objective To investigate the value of urine liver?type fatty acid?binding proteins(L?FABP) for early diagnosis and progress predicting of acute kidney injury(AKI)after lung transplantation. Methods Urine L?FABP and Scr blood samples in perioperative periods of 119 lung transplant recipients (hospitalized between 2013?2014)were involved in the research. Patients were divided into AKI group and non?AKI group according to KDIGO. Changes in urine L?FABP and Scr of two groups at various time points were recorded. Results Of 119 patients,57 developed AKI after surgery. Urine L?FABP from 0 h to 48 h in the two groups increased significantly, and the difference at 6 h to 48 h between the two groups is significant. In terms of diagnostic value,ROC area of urine L?FABP at 6h is 0.818. When 2254.52 ng/mg Cr was taken as diagnostic dividing line ,sensitivity and specificity was 0.782 and 0.814. In predicting AKI progression ,AUC below AUC of urine L?FABP 0.852. When 4313.17 ng/mgCr was taken as diagnostic dividing line ,sensitivity and specificity was 0.867 and 0.700. Conclusion Urinary L?FABP appears to be a sensitive and specific marker of AKI in lung transplant recipients ,could be a biological marker in the early diagnosis and progression tendency of AKI.

Objective To investigate the influence of prenatal integrated intervention model for the childbirth respond and birth outcomes of primiparous mothers. Methods A total of 417 cases patients were the objects for the study, which were treated in our hospital from Jan 2012 to Feb 2014, all the patients were divided into control group (203 cases) and intervention group (214 cases). After 28 weeks pregnant, the control group received regular check-ups and care, while the intervention group received comprehensive intervention contrary to the four paths of the sources of self-efficacy. Results After intervention, the score of OE-16 scores and EE-16 score of control group with only a small increase, while the intervention group was increased obviously, and the difference between the two groups was statistically signifi-cant(P<0.05). The degree of childbirth pain of intervention group was more slight than control group, and the difference between the two groups was statistically significant (P<0.05). In addition, except the scores of 1 min Apgar was no dif-ference between two groups, the childbirth time and the cesarean section rate of intervention group was improved com-pared with control group, and the difference was statistically significant (P<0.05). Conclusion The prenatal comprehen-sive intervention is benefit to improve the childbirth early self-efficacy levels and reduce the cesarean section rate, worthy of further promoting in clinical obstetrics.
