ObjectiveTo investigate the risk factors for postoperative pulmonary infection in patients with primary liver cancer through a retrospective analysis, and to provide a reference for appropriate preventive measures in clinical treatment. MethodsA total of 286 patients with liver cancer who visited Department of Hepatology, 180 Hospital of PLA, from May 2011 to December 2015 were enrolled, and according to the presence or absence of postoperative pulmonary infection, these patients were divided into infection group (36 patients) and non-infection group (250 patients). The factors for postoperative pulmonary infection were analyzed. The t-test was used for comparison of continuous data between groups, the chi-square test was used for comparison of categorical data between groups, and logistic multivariate regression analysis was used to analyze the risk factors for postoperative pulmonary infection. ResultsThe univariate analysis showed that age distribution, smoking history, diabetes, intraoperative blood transfusion volume, and the indwelling time of abdominal drainage tube showed significant differences between the two groups (all P＜0.05). The multivariate analysis showed that smoking history, diabetes, intraoperative blood transfusion volume, and the indwelling time of abdominal drainage tube were independent risk factors for postoperative pulmonary infection in patients with primary liver cancer (all P＜0.05). Among the anesthesia-related factors, application of single-use medical devices and perioperative antibacterial agents significantly reduced the incidence rate of postoperative pulmonary infection (both P＜0.05). ConclusionSmoking history, diabetes, intraoperative blood transfusion volume, the indwelling time of abdominal drainage tube, no use of single-use medical devices during anesthesia, and no use of perioperative antibacterial agents are risk factors for postoperative pulmonary infection in patients with primary liver cancer. Corresponding preventative and treatment methods can effectively prevent the development of postoperative pulmonary infection.

Objective:To investigate the diagnostic value and imaging characteristics of MRI combined with 18F-fluorodeoxyglucose (FDG) positron-emission tomography (PET)/CT in focal cortical dysplasia (FCD) complicated with refractory epilepsy. Methods:A retrospective analysis was performed on 42 patients with FCD complicated with refractory epilepsy who were admitted to the Affiliated Hospital of Jining Medical University from January 2017 to December 2022. All patients underwent preoperative MRI and 18F-FDG PET/CT, and PET/MRI fusion was performed on the images. Chi-square test and Kappa consistency test were used to compare the localization diagnostic efficacy of PET/CT, MRI and PET/MRI fusion for epileptic foci. The patients were categorized based on gender, lesion location, pathological type, seizure type, and efficacy. Independent sample t-test and analysis of variance were used to compare maximum standardized uptake (SUVmax) values and asymmetry index (AI) of the patients between different groups. Results:Among the 42 patients, the positive rates of MRI, PET/CT, PET/MRI fusion examinations were 85.7%(36/42), 95.2%(40/42), 100.0%(42/42), the lateral localization rates were 71.4%(30/42), 92.9%(39/42), 95.2%(40/42), and the localization rates were 57.1%(24/42), 81.0%(34/42), 88.1%(37/42), respectively. There were significant differences in the lateral localization rates and localization rates of epileptogenic foci between MRI and PET/CT (χ 2=6.574, P=0.010; χ 2=5.570, P=0.018). There were significant differences in the positive rates of lesions, the lateral localization rates and the localization rates of epileptogenic foci between MRI and PET/MRI fusion (χ 2=6.385, P=0.012; χ 2=8.571, P=0.003; χ 2=10.118, P=0.001). There were no significant differences in the positive rates of lesions between MRI and PET/CT, and in the positive rates of lesions, the lateral localization rates and localization rates of epileptogenic foci between PET/CT and PET/MRI fusion (χ 2=2.184, P=0.139; χ 2=2.024, P=0.155; χ 2=0.210, P=0.647; χ 2=0.819, P=0.365). The Kappa consistency test of PET/CT and PET/MRI fusion imaging was performed for the location of epileptogenic foci, and the Kappa=0.721 was obtained, indicating that they were consistent in the location of epileptogenic foci. The SUVmax values of patients with temporal lobe epilepsy were lower, and the AI values were higher than that of patients with extra temporal lobe epilepsy (7.4±1.3 vs 9.6±1.6, 15.5±2.6 vs 12.9±2.4; t=5.154, 6.083; P=0.001, 0.001). The SUVmax values of patients with good efficacy (according to the Engel efficacy grading system, grades Ⅰ-Ⅱ indicating good efficacy) were higher, and the AI values were lower than that of patients with poor efficacy (according to the Engel efficacy grading system, grades Ⅲ-Ⅳ indicating poor efficacy; 9.5±1.9 vs 7.9±2.1, 13.5±3.3 vs 14.8±3.0; t=2.789, 3.722; P=0.042, 0.029). There were no significant differences in SUVmax and AI values among different genders, pathological types and seizure types (all P>0.05). Conclusions:The imaging characteristics of patients with different types of FCD complicated with refractory epilepsy are different. PET/MRI fusion is better than MRI in the diagnosis of FCD complicated with refractory epilepsy, and is consistent with PET/CT in the location of epileptogenic foci.

Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.

Objective:To investigate the clinical efficacy and prognostic influencing factors of open abdomen technique for acute pancreatitis with abdominal compartment syndrome (ACS).Methods:The retrospective cohort study was conducted. The clinical data of 186 patients of acute pancreatitis with ACS who were admitted to 6 hospitals, including 65 cases in the 910th Hospital of Joint Logistics Support Force of Chinese People′s Liberation Army, 46 cases in the First Affiliated Hospital of Wenzhou Medical University, 33 cases in the Fujian Provincial Hospital, 31 cases in the Second Affiliated Hospital of Fujian Medical University, 7 cases in the People′s Hospital Affiliated to Quanzhou Medical College, 4 cases in the Shishi General Hospital, from January 2013 to December 2020 were collected. There were 142 males and 44 females, aged (43±8)years. Observation indica-tors: (1) patients conditions after being treatment with open abdomen technique; (2) analysis of clinical characteristics in patients with different treatment outcomes; (3) changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes; (4) influencing factors for prognosis of patients. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or the continuity correction chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Spearman correlation analysis was used for correlation analyses. The COX regression model was used for univariate analysis and COX regression model with forward regression was used for multivariate analysis. Results:(1) Patients conditions after being treatment with open abdomen technique. Intra-abdominal pressure, oxygena-tion index, levels of lactic acid and sequential organ failure score of the 186 patients were (23.3±1.9)mmHg (1 mmHg=0.133 kPa), (121±24)mmHg, (5.0±3.4)mmol/L and 10.4±3.6 before the treatment with open abdomen technique and (11.2±2.9)mmHg, (222±38)mmHg, (3.2±2.1)mmol/L and 4.4±2.3 at postoperative 168 hours, showing significant differences in time effects before and after the treatment ( Ftime=855.26,208.50, 174.91,208.47, P<0.05). (2) Analysis of clinical characteristics in patients with different treatment outcomes. Of the 186 patients, 166 cases survived and were discharged, and 20 cases died during hospitalization. Age, sequential organ failure score, duration of ACS and levels of lactic acid during hospitalization before the treatment with open abdomen technique were (41±7)years, 9.4±3.4, 13(10,21)hours and (4.2±0.6)mmol/L in surviving patients, versus (45±6)years, 11.5±2.4, 65(39,84)hours and (5.2±0.5)mmol/L in dead patients, respectively, showing significant differences between them ( t=-2.10, -2.71, Z=-5.36, t=-7.16, P<0.05). Duration of postoperative acute gastro-intestinal injury, duration of continuous renal replacement therapy, time to liberation from mech-anical ventilation, duration of vasoactive drugs therapy, cases undergoing early abdominal closure, cases without intestinal fistula or with postoperative high-order intestinal fistula and low-order intestinal fistula during hospitalization after the treatment with open abdomen technique were 4(2,6)days, 4(3,7)days, 34(21,41)days, 3(2,6)days, 126, 131, 23, 12 in surviving patients, versus 13(10,17)days, 10(8,18)days, 0(0,3)days, 8(6,12)days, 1, 2, 15, 3 in dead patients, respectively, showing significant differences between them ( Z=-5.60, -3.75, -3.64, -3.06, χ2=41.43, 45.86, P<0.05). (3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.
