Objective To compare the X-ray features between Hirschsprung alied disease (HAD)and Hirschsprung disease ( HD), and analyze the differentiations. Methods From December 2004 to December 2009, nineteen cases of HAD, aged from 30 days to 10 years (median, 14 months), received barium enema examinations in our institution. Other 19 cases with HD, also received barium enema examinations, were chosen randomly. They were aged from 42 days to 8 years ( median, 8 months). The imaging features of HAD and HD were analyzed retrospectively. The incidence rate of colon stenosis,"truncation sign" and spasm notch and R/C ratio (the longest diameter of rectum/colon) were calculated and compared between these two groups. In all these cases, diagnosis was confirmed by postoperative histopathology. The position of barium retained was also evaluated. These parameters of both groups were compared by x2 and Fisher test. Results There was statistical significance in the incidence rate of colon stenosis between HAD (9/19) and HD (18/19) (x2 = 10.364, P ＜0.01). However, there was no statistical significance in "truncation sign" and spasm notch between HAD (4/19 and 3/19, respectively)and HD ( 1/19 and 1/19, respectively) (P ＞0. 05 for both). R/C ratio was 0. 42 ±0. 15 in HAD group and 0.29±0. 12 in HD group, and there was statistical significance between them (t =2.892,P＜0.01). In HAD group, barium retained in distal sigmoid colon in 1 case (1/19), in distal descending colon in 7 cases (7/19), in distal transverse colon in 1 case (1/19), in total colon in 6 cases (6/19); However, in HD group, barium retained in distal rectum in 3 cases (3/19), in distal sigmoid colon in 13 cases ( 13/19), in distal descending colon in 3 cases (3/19). Conclusions There were some differences in the imaging features between HAD and HD though they presented similar clinic experience. HAD cases presented a lower incidence rate of colon stenosis and a higher R/C ratio than HD cases. In HAD cases, the most common site of barium retained is distal descending colon, while in HD cases, it is distal sigmoid colon.

Objective:To explore the prognostic risk factors of patients with multiple injuries and establish a nomogram prediction model.Methods:The clinical data of 291 patients with multiple injuries admitted to the Emergency Intensive Care Unit (EICU) of General Hospital of Ningxia Medical University were collected, including sex, age, open injury, norepinephrine use, mechanical ventilation, time to hospital after injury, distance to hospital, relative lymphocyte value, platelet count, lactic acid, injury severity score (ISS), acute physiology and chronic health evaluationⅡ (APACHE Ⅱ), Glasgow coma scale (GCS), number of blood transfusions, number of operations, and previous history of diabetes, hypertension and smoking within 24 h after admission. According to whether the condition worsened during the hospitalization of EICU, the patients were divided into the deterioration group and improvement group. SPSS26.0 software was used for statistical analysis of the data, univariate and multivariate analysis were used to screen the factors affecting the prognosis of patients with multiple injuries, receiver operating characteristic (ROC) curve and forest chart were drawn, and the influencing factors in binary Logistic regression model were used to make the nomogram.Results:Mechanical ventilation, norepinephrine use, age, relative lymphocyte value, lactic acid, APACHE-II score, GCS score, and number of operations were significant for predicting the prognosis of patients with multiple injuries ( P<0.05). The independent influencing factors obtained by binary Logistic regression model were age, lactic acid, APACHE-Ⅱ score and number of operations. ROC curve analysis showed that the area under the curve was the largest in multi-factor combined prediction, followed by APACHE-Ⅱ score. The diagnostic cut-off value of each index was as follows: age >58 years old, relative lymphocyte value≤ 8.62%, lactic acid >1.72, APACHE-Ⅱ score >16, GCS score≤ 6, and number of operations≤ 0. The R software was used to establish a nomogram of the influencing factors in the binary Logistic regression model, which had good predictive value. Conclusions:The nomogram constructed by age, relative lymphocyte value, lactic acid, APACHE-Ⅱ score, GCS score, number of operations, mechanical ventilation, and norepinephrine use has a good predictive value for the prognosis of patients with multiple injuries, and is worthy of promotion..

Objective:To explore the risk factors of sepsis in patients with multiple trauma and construct a nomogram prediction model.Methods:The data of patients with multiple injuries admitted to the emergency intensive care unit (EICU) of the General Hospital of Ningxia Medical University from January 2021 to April 2022 were respectively collected. Inclusion criteria: (1) meet the diagnostic criteria for multiple injuries; (2) the time from injury to admission ≤ 24 hours; (3) age>18 years old; (4) all examination or rescue measures were approved by the patient or the patient's family; (5) the patient's clinical data were complete. The patients were divided into sepsis group and non-sepsis group according to the definition of Sepsis 3.0 at the 28-day of EICU hospitalization. The receiver operating characteristic curve was drawn. Logistic regression analysis was applied to determine the independent predictors for sepsis, and the nomogram was constructed.Results:A total of 291 patients were included, including 102 in the sepsis group and 189 in the non-sepsis group. Multivariate logistic analysis revealed that age, acute physiology and chronic health status score (APACHE) Ⅱ, Glasgow Coma Scale (GCS), injury severity score (ISS), sequential organ failure assessment (SOFA) within 24 hours after admission, blood transfusion frequency, the application of norepinephrine, mechanical ventilation, pathogenic culture results, and history of diabetes were independent factors influencing the occurrence of sepsis. A nomogram model was constructed by combining these variables (AUC=0.913, 95% CI: 0.847-0.942), and the model had a good fitting calibration curve. Conclusions:The nomogram constructed by age, APACHE-Ⅱ, GCS score, SOFA score, ISS score, number of blood transfusions, mechanical ventilation, norepinephrine drug use, pathogenic culture and diabetes has a good predictive value for sepsis in patients with multiple trauma in the later stage, which is worth promoting.
