Objective:Metabolic alkalosis has raised concerns in patients receiving continuous renal replacement therapy (CRRT) via regional citrate anticoagulation (RCA). This study searched for alkalosis-related factors and mechanisms.Methods:It's a retrospective study of alkalosis in patients who received CRRT for at least 12 hours with RCA in a tertiary hospital between April 2017 and April 2020. Demographic features, baseline laboratory results, CRRT metrics and laboratory results at 12h after CRRT was recorded. Patients was grouped based on whether alkalosis exist at 12h after CRRT, and multivariable logistic regression analysis was used to identify risk factors for alkalosis during CRRT with citrate anticoagulation.Results:The 59 patients meeting the inclusion criteria were 49% male, with a mean age of (55±18) years old, and 42% had alkalosis by 12 hours after CRRT. No significant differences in demographic features or laboratory results were observed patients with or without alkalosis. CRRT metrics, including blood flow rate, citrate rate, replacement fluid rate and total effluent rate, were significantly different among groups ( P<0.01). Multivariable Logistic regression analysis indicated that the citrate rate was a risk factor for alkalosis ( OR=1.088, 95% CI 1.020-1.161, P =0.010). In patients receiving no NaHCO 3 and without alkalosis, the linear regression analysis described the relationships of citrate with replacement fluid rate (citrate rate = 0.090 × replacement fluid rate + 56.581; R2 = 0.6918) and total effluent rate (citrate rate = 0.099 × total effluent rate + 2.449). Conclusions:This retrospective observational study demonstrated that CRRT metrics are highly associated with alkalosis after 12 hours of CRRT. Without NaHCO3 infusion, a 10-fold linear correlation was observed between citrate and total effluent rate in patients without metabolic alkalosis.

Bonding technology has made tremendous progress over the past 50 years,but there are still some unresolved issues re-garding the durability of the bonding interface.In order to improve the durability and stability of dentin bonding,researchers have been trying to develop adhesives with more biological functions,such as promoting dentin remineralisation,inhibiting enzyme activity at the bonding interface,and enhancing collagen cross-linking.Based on the above starting point,this paper evaluates adhesive system mono-mers with multiple functions through a review of scientific papers published in recent years,in the hope of improving the development of new adhesive systems and reducing the degradation of the bonding interface.

Objective:To develop a perinatal depression screening scale for Chinese urban version and test its reliability and validity.Methods:Naturally conceived women who were≥12 weeks of gestation and had regular prenatal examinations or delivered within four weeks in Xi'an and Foshan were recruited using convenience sampling. Initial entries were created through clinical interviews and expert validation of 50 of these pregnancies. Further item screening and testing for reliability and validity using correlation analysis, critical ratio method, homogeneity test, and factor analysis were performed. The final questionnaire was formed and then used to test the subjects. Fifty women who had completed the questionnaire effectively were selected for retesting 10 to 15 days after the initial evaluation. A structural equation model was constructed using the Edinburgh Postpartum Depression Scale (EPDS) as the reference criterion to conduct the scale's exploratory and confirmatory factor analysis. The receiver operating characters curve was used to determine the cut-off point of the scale.Results:(1) 1 300 questionnaires were issued, and 1 049 valid questionnaires were received with a recovery rate of 80.7%. Among them, 601 were used for exploratory and correlation analysis, and 448 were used for confirmatory factor analysis. (2) The initial entries of the scale totaled 63. After eliminating indicators that did not meet the requirements for item analysis, the final scale consisted of 22 entries in total. The final scale consisted of six dimensions, including "abnormal mood", "loss of interest and pleasure," "sleep disorder," "self-blame and guilt," "decline in conscious thought ability," and "lack of energy". (3) The correlation coefficients between the above six dimensions and EPDS were 0.609, 0.322, 0.423, 0.522, 0.545, and 0.516, respectively. The one between the total scale and EPDS was 0.715 (all P<0.01). (4) The confirmatory factor analysis of each model and the scale showed an acceptable fit and a stable factor structure with indices Chi-square/degrees of freedom =2.504, square root of approximation error=0.058, standardized root mean square residual=0.048, comparative fit index=0.925, Tueker-Lewis index=0.911. After retaining 22 items, the Cronbach's coefficients of the six dimensions ranged from 0.708 to 0.870. (5) The test-retest reliability of the total scale, six dimensions, and 22 items were 0.936, 0.786-0.846, and 0.720-0.886, respectively. (6) The receiver operating characteristic curve of the scale was drawn with EPDS≥13 as the cut-off value, and the area under the curve (AUC) of EPDS was 0.808 (95% CI: 0.744-0.872). When the original cut-off point was 21, the Youden index was the max (0.561), with sensitivity and specificity of 0.952 and 0.609, respectively. The Kappa value was 0.691, indicating that the scale was consistent with EPDS. Conclusion:This study preliminarily established a Chinese urban version of the perinatal depression screening scale with a stable factor structure and good reliability and validity.

Objective:To analyze the influencing factors of the medical insurance balance of hospitalization expenses for gastric cancer surgery patients under DRG payment, for reference for promoting the reform of DRG payment in public hospitals and controlling hospitalization expenses reasonably.Methods:The gastric cancer patients enrolled in the gastroenterology department of a tertiary comprehensive hospital from January to July 2022 were selected as the research subjects. The indicators such as patient age, medical insurance balance, hospitalization expenses and their composition were extracted from the hospital information management system and the medical insurance settlement system a certain city. Descriptive analysis was conducted for all data, and stepwise multiple linear regression was used to analyze the influencing factors of patients′ medical insurance balance. Monte Carlo simulation method was used to simulate different combination scenarios of various influencing factors to analyze the probability of medical insurance balance.Results:A total of 205 patients were contained, including 117 in the medical insurance balance group and 88 in the loss group. The difference in hospitalization expenses and medical insurance balance between the two groups of patients were statistically significant ( P<0.05). The intervention of medical insurance specialists, correct DRG enrollment, parenteral nutrition preparation costs, anti infective drug costs, examination costs, and consumables costs were the influencing factors of patient medical insurance balance ( P<0.05). Through Monte Carlo simulation verification, patients with different cost parenteral nutrition preparations, or different anti infective drug schemes had the higher probability of medical insurance balance in the scenario where the medical insurance commissioner intervenes and the DRG enrollment was correct. Conclusions:The hospital adopted interventions from medical insurance specialists to ensure the correct DRG enrollment of patients, accurate use of parenteral nutrition and anti infective drugs, and reasonable control the cost of examinations and consumables, which could increase the probability of medical insurance balance for gastric cancer surgery patients. In the future, hospitals should further promote the procurement of drug consumables in bulk, reduce unnecessary examinations, develop standardized perioperative nutritional interventions and anti infection treatment pathways, ensure the accuracy of DRG enrollment, optimize clinical diagnosis and treatment pathways to improve the efficiency of medical insurance fund utilization and provide high-quality medical services for patients.
