Objective To explore the effect of urine mixing degree on 24-hour urinary total protein(24 h UTP)in patients with chronic kidney disease(CKD).Methods From October 1,2023 to December 31,2023,30 hospitalized patients who needed to complete 24 h UTP testing in Zhongshan Hospital,Fudan University were selected.A 5 L unified container was used to collect urine for 24 hours.After collection and one hour's standing,the urine sample was divided into upper,middle,and lower equal parts according to volume,which was defined as direct-sampling group.Then,the urine samples were fully mixed with a magnetic stirrer and sampled again according to the above-mentioned three-equal sampling method,which was defined as mixed-sampling group.The generalized estimating equation was used to compare the urinary protein concentration before and after mixing and at different sampling location.Results The results of generalized estimating equation showed that after controlling the variable"sampling position",there was no significant difference in urinary protein concentration between the direct-sampling group and the mixed-sampling group.After controlling the variable"mixing method",there was still no significant difference in urinary protein concentration at different sampling positions.After adjusting the covariates such as age,gender,and estimated glomerular filtration rate(eGFR),the results were consistent.Conclusions With standard protocol,the entire 24-hour urine sample is a relatively even-distributed solution.After the total urine collection is completed,the temporary sample can be directly extracted from any level of the original urine within 1 hour,and the urine protein concentration of the sample multiplied by the urine volume can reflect the 24 h UTR.

Background/Aims: This study aimed to assess the impact of INTERCEPT Foam Spray (IFS) application on delayed endoscope reprocessing through microbiological surveillance culture (MSC). Methods: A quasi-experimental, matched-comparison pilot study was conducted using gastrointestinal endoscopy. IFS was applied to the endoscopes after precleaning and before reprocessing the next day. An equal number of endoscopes, matched by endoscope type, were subjected to routine reprocessing. The MSC were subjected to high-level disinfection to detect any contamination. Data were analyzed using the chi-square test or Fisher exact test (categorical data) and Student t-test (continuous data). Results: In total, 150 MSCs were collected from 42 endoscopes. Positive MSCs were observed in 4.0% (4/75) of the sprayed group and 1.3% (1/75) of the control group (95% confidence interval, 30.34–0.31; p>0.05), all of which were contributed by colonoscopes. Colonoscope were more prone to positive MSC (mean difference in percentage, p<0.05). Mean spraying hours were not associated with detected growth (11.7% vs. 13.6%; 95% confidence interval, 1.43 to –5.27; p>0.05), with environmental and skin flora being the primary contaminants. Conclusions IFS may be applied when delayed endoscope processing is necessary, but with caution when applied to colonoscopes. However, further research is warranted to verify the result.

Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.

OBJECTIVES: To systematically evaluate the value of the platelet-to-lymphocyte ratio (PLR) in predicting coronary artery lesions (CAL) in Chinese children with Kawasaki Disease (KD). METHODS: A comprehensive search was conducted in databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang Data, China Biomedical Literature Database, and China Science and Technology Journal Database from inception to December 2022. The quality of the included literature was assessed using the Newcastle-Ottawa Scale, and a Meta analysis was performed using Stata 15.1. RESULTS: A total of ten published reports, involving 3 664 Chinese children with KD, were included in this Meta analysis, of whom 1 328 developed CAL. The Meta analysis revealed a sensitivity of 0.78 (95%CI: 0.71-0.83), specificity of 0.71 (95%CI: 0.61-0.80), overall diagnostic odds ratio of 8.69 (95%CI: 5.02-15.06), and an area under the curve of the summary receiver operating characteristic of 0.82 (95%CI: 0.78-0.85) for PLR in predicting CAL in the children with KD. The sensitivity, specificity, and area under the curve of summary receiver operating characteristic were lower for PLR alone compared to PLR in combination with other indicators. Sensitivity analysis demonstrated the stability of the Meta analysis results with no significant changes upon excluding individual studies. However, a significant publication bias was observed (P<0.001). CONCLUSIONS PLR demonstrates certain predictive value for CAL in Chinese children with KD.

Objective:To explore the risk factors of renal function progression in patients with acute renal injury (AKI) after moderate hypothermic circulatory arrest surgery in acute aortic dissection (AD).Methods:Retrospective analysis was made base on the data of 290 patients with acute AD who underwent surgical treatment from January 2014 to August 2022 in the Affiliated Hospital of Jining Medical University. According to the Kidney Disease: Improving Global Outcomes (KDIGO) AKI diagnostic criteria in 2015, patients with AKI after surgery were selected as the study objects. Patients with progressive deterioration of renal function or required continuous renal replacement therapy after AD operation were defined as the progression group of AKI, the other patients with gradual improvement of renal function after AD operation were defined as the improvement group of AKI. The clinical data of the two groups were compared, and the risk factors for the progression of AKI after AD were analyzed by multivariate logistic regression.Results:A total of 290 AD surgeries were completed, of which 143 cases developed AKI after surgery, including 81 cases in AKI progression group and 62 cases in AKI improvement group. In the progression group of AKI, before surgery the proportion of patients with coronary heart disease: 24.7% (20/81) vs.11.3% (7/62), serum creatinine (Scr) >133 μmol/L: 24.7% (20/81) vs. 3.2% (2/62), pericardial tamponade: 22.2% (18/81) vs. 8.1% (5/62), lower limb ischemia: 25.9% (21/81) vs. 3.2% (2/62) were significantly increased. Postoperative acute physiology and chronic health evaluation Ⅱ (APACHE) score: 14.00 (9.00, 19.75) scores vs. 10.00 (7.00, 12.00) scores, ICU hospitalization days: 8 (5, 13) d vs. 5 (3, 7) d, postoperative mortality: 24.7%(20/81) vs. 1.6%(1/62), the proportion of KDIGO phase 3 ratio: 46.9%(38/81) vs. 3.2%(2/62), postoperative infection: 61.7%(50/81) vs. 38.7% (24/62), low cardiac output syndrome: 29.6% (24/81) vs. 6.5% (4/62), cerebral infarction complications: 38.2%(31/81) vs. 16.1%(10/62), and mortality after surgery were also higher. Compared with improvement group of AKI, all differences were statistically significant ( P<0.05). Multivariate Logistic regression analysis showed that preoperative lower limb ischemia ( OR = 9.430, 95% CI 1.975 to 45.032, P = 0.005), postoperative low cardiac output syndrome ( OR = 5.288, 95% CI 1.543 to 18.126, P = 0.008), and postoperative infection ( OR = 2.273, 95% CI 1.022 to 5.057, P = 0.044) were independent risk factors for the progression of AKI after AD surgery. Conclusions:The independent risk factors of renal function progression in patients with AKI after hypothermic circulatory arrest surgery in acute AD include preoperative lower limb ischemia, postoperative low cardiac output syndrome, and postoperative infection.

Objective:To identify the risk factors and develop nomogram for idiopathic chronic pancreatitis (ICP) patients with common bile duct stricture (CBDS).Methods:The clinical data of 1 633 ICP patients admitted to the Department of Gastroenterology of First Affiliated Hospital of Naval Medical University from January 2000 to December 2013 were collected retrospectively and prospectively. The patients were classified into CBDS group ( n=259) and non-CBDS group ( n=1 374) according to whether CBDS occurred. The cumulative incidence of CBDS after the onset and diagnosis of ICP were calculated by Kaplan-Meier method. After excluding patients who had developed CBDS before/or at the diagnosis of ICP, the remaining patients were randomly divided into the training set and the validation set. The univariate and multivariate Cox proportional hazards regression analysis were used to establish a risk predicting nomogram for CBDS after ICP onset. Its clinical application value was evaluated through the consistency index (C index). Results:15.9%(259/1 633) of patients developed CBDS after the onset of ICP. The cumulative incidence of CBDS at 3, 5, and 10 years after the onset of ICP was 9.6% (95% CI 0.082-0.111), 11.2% (95% CI 0.097-0.129) and 16.2% (95% CI 0.142-0.184), respectively. 9.4%(143/1 517) of patients developed CBDS after the diagnosis of ICP. The cumulative incidence of CBDS at 3, 5, and 10 years after the diagnosis of ICP was 8.3% (95% CI 0.069-0.099), 8.9% (95% CI 0.074-0.105) and 13.3% (95% CI 0.110-0.162), respectively. Univariate analysis found that factors including gender, age at onset of ICP, age at diagnosis of ICP, being adolescents at onset of ICP, smoking history, alcohol intake, initial manifestations, pancreatic duct stones, fatty steatorrhea, main pancreatic duct (MPD) morphology and pain type were significantly different between CBDS group and non-CBDS group. Multivariate analysis showed that male ( HR 2.134, 95% CI 1.336-3.408), age at diagnosis of ICP ( HR 1.038, 95% CI 1.024-1.052), first manifestation (pancreatic abdominal pain) and main duct morphology (complex lesion) were identified as independent risk factors for CBDS in ICP patients. A nomogram for predicting CBDS after ICP diagnosis was established based on the above four variables. The nomogram had a C-index of 0.740 (95% CI 0.700-0.790) for internal validation in the training set and 0.650 (95% CI 0.570-0.730) for external validation in the validation set. Conclusions:The nomogram established in this study can evaluate the risk of developing CBDS in ICP patients, benefit the early diagnosis and timely intervention of CBDS in clinical practice, and prevent potential related complications.

OBJECTIVE To evaluate the correlation between the solid dispersion(SD) powder properties and the relative crystallinity(RC) during SD recrystallization. METHODS Andrographolide was used as model drug, polyvinylpyrrolidone K30, polyethylene glycol 8000, Poloxam 188, Soluplus® as carrier materials, 12 SD powders were prepared by three preparation processes, and then the SD powder properties were determined. Afterwards, the principle component analysis and partial least squares analysis(PLS) were used to evaluate the correlation between the SD powder properties and RC during SD recrystallization. RESULTS The correlation model was successfully established by partial least square method between the SD powder properties and the RC. The VIP value of particle size parameter D(0.5) was >1.2, which indicated that the particle size was the key factor affecting the recrystallization of SD powder. CONCLUSION In practical work, SD powder with different particle size parameters can be obtained by different preparation methods or by adjusting the process parameters of the selected preparation method, so as to improve the recrystallization stability of SD.
