  • Clinical Predictive Score for Acute Kidney Injury after Cardiac Surgery in Adults

    Objective To analyze risk factors of acute kidney injury (AKI) after cardiac surgery in adults and develop a clinical score system to predict postoperative AKI. Methods Clinical data of 3 500 consecutive patients undergoing cardiac surgery from June 2010 to April 2011 in Beijing Anzhen Hospital of Capital Medical University were retrospectively analyzed. According to whether they had postoperative AKI,all these patients were divided into AKI group and non-AKI group. AKI group was consisted of 1 407 patients (40.2%) with a mean age of 58±12 years,including 1 004 male patients (71.4%). The non-AKI group was consisted of 2 093 patients (59.8%) with a mean age of 55±13 years,including 1 259 male patients (60.2%). Predictive score system of postoperative AKI was established by univariate analysis between the AKI and non-AKI group and multivariate logistic regression and then verified. Results The predictive score system was as followed:male gender (2 points),every 5 years older than 60 years (1 point),diabetes mellitus (2 points),preoperative use of angiotensin converting enzyme inhibitor or angiotensin AT1 receptor blocker (1 point),every 10 ml / (min·1.73 m2) of preoperative estimated glomerular filtration rate (eGFR) under 90 ml / (min·1.73m2) (1 point),preoperative NYHA class Ⅳ (3 points),cardiopulmonary bypass time>120 minutes (2 points),intraoperative hypotension duration>60 minutes (2 points),postoperative hypotension duration>60 minutes (3 points),postoperative peak dosage of intravenous furosemide>100 mg/day (3 points),postoperative peak dosage of intravenous furosemide 60-100 mg/day (2 points),and postoperative mechanical ventilation time>24 hours (2 points). The predictive score system presented a good discrimination ability with the area under the receiver operating characteristic(ROC)curve of 0.738 with 95% CI 0.707 to 0.768,while it also presented a good calibration with Hosmer-Lemeshow statistic (P=0.305). Conclusion A clinical predictive score system for AKI after cardiac surgery in adults is established,which may help clinicians implement early preventive interventions.

  • Exploration of key genes and mechanisms of depression aggravating Crohn disease based on bioinformatics

    Objective To explore key genes and mechanisms of depression aggravating Crohn disease. Methods In March 2023, the Public Health Genomics and Precision Health Knowledge Base and Gene Expression Omnibus database were used to identify the overlapping differentially expressed genes between Crohn disease and depression and the key genes were screened by Metascape, STRING, Cytoscape, and protein interaction network analysis. The Gene Expression Omnibus database was used to analyze the correlations between key genes and clinical pathologies such as Crohn Disease Endoscopic Index of Severity and intestinal microvilli length. Results There were 137 overlapping differentially expressed genes between Crohn disease and depression, and 25 key genes were further screened out. Among them, CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A genes were significantly correlated with multiple clinical parameters. The functions of PROK2 and PROK2-related genes were mainly enriched in neutrophil and granulocyte migration, neutrophil and granulocyte chemotaxis, etc. Conclusions There are 25 key genes, especially CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A, that possibly contribute to the establishment and deterioration of Crohn disease caused by depressive disorder. Among these genes, PROK2 showes the possibility of regulating immune cell (neutrophils and CD8+ T cells) infiltration.

  • Analysis on the analgesic effect of Chinese medicine acupuncture in daytime operation oftotal extraperitoneal inguinal hernia repair

    ObjectiveTo explore the effectiveness of traditional Chinese medicine (TCM) acupuncture analgesia after laparoscopic total extraperitoneal inguinal hernia repair (TEP), aiming to reduce the use of analgesics post-surgery. MethodsPatients who underwent unilateral TEP in the Department of Hernia and Abdominal Wall Surgery at our hospital from May 2022 to May 2023 were selected as research subjects. Those who met the inclusion and exclusion criterias were randomly assigned to three groups: TCM acupuncture analgesia group, traditional Chinese medicine acupuncture analgesia plus western medicine analgesia group (referred to as Chinese and western medicine analgesia group), and western medicine analgesia group. The basic information, postoperative numerical rating scale (NRS) pain scores, postoperative recovery indicators, and complication rates of the three groups were analyzed and compared.ResultsThere was no statistically significant differences in the basic data of patients across the three groups (P>0.05). There were significant differences in NRS score, recovery time of intestinal function, first urination time after operation and first ambulation time after operation at each time point after analgesia (6 h, the next morning, 48 h, 72 h and 96 h after operation) among the three groups (P<0.05). The NRS scores in both the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group were lower than those in the western medicine analgesia group (P<0.05), Additionally, postoperative recovery outcomes were better in the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group compared with the western medicine group (P<0.05). There was no significant difference of the above results compared between the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group (P>0.05). There was no significant difference in postoperative complications among the three groups (P>0.05). ConclusionTCM acupuncture analgesia following TEP surgery is effective and leads to improved postoperative recovery compared with the use of oral analgesics alone, without an increase in adverse reactions.
