Objective:To investigate the value of combined detection of biomarkers in early diagnosis and prognosis of patients with septic myocardial injury.Methods:The clinical data of 103 patients with sepsis admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Baotou Medical College of Inner Mongolia University of Science and Technology from October 2018 to January 2021 were enrolled. According to the cardiac troponin I (cTnI) at admission of ICU, they were divided into septic myocardial injury group (cTnI ≥ 0.15 μg/L) and non-septic myocardial injury group (cTnI < 0.15 μg/L). The serum levels of heart-type fatty acid-binding protein (H-FABP), procalcitonin (PCT), C-reactive protein (CRP), MB isoenzyme of creatine kinase (CK-MB), cTnI and N-terminal pro-brain natriuretic peptide (NT-proBNP) within 6 hours after ICU admission and the worst value of acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score within 24 hours after ICU admission in 103 patients was recorded as well as the 28-day prognosis of patient with septic myocardial injury. Spearman correlation analysis was used to analyze the correlation of each index; receiver operating characteristic curve (ROC curve) was drawn, and the area under ROC curve (AUC) was calculated to analyze the early diagnosis and prognostic value of each index and APACHEⅡ score alone or combined detection in patients with septic myocardial injury.Results:① Among 103 patients with sepsis, 58 patients were complicated with myocardial injury and 45 patients were not complicated with myocardial injury. The serum levels of PCT, CRP, NT-proBNP, CK-MB, cTnI, H-FABP and APACHEⅡ score in patients with septic myocardial injury were significantly higher than those in patients without septic myocardial injury [PCT (μg/L): 3.46±1.35 vs. 1.89±0.43, CRP (mg/L): 81.1±26.8 vs. 65.3±19.1, NT-proBNP (U/L): 8 261.4±2 346.9 vs. 6 120.2±1 809.6, CK-MB (U/L): 15.89±6.25 vs. 12.14±4.24, cTnI (μg/L): 1.50 (0.91, 2.21) vs. 0.18 (0.16, 0.19), H-FABP (μg/L): 26.45±8.24 vs. 12.82±5.73, APACHEⅡ score: 24.0 (18.0, 29.0) vs. 16.0 (14.0, 18.0), all P < 0.01]. Spearman correlation analysis showed that PCT, CRP and APACHEⅡ scores were positively correlated with NT-proBNP, CK-MB, cTnI and H-FABP. ROC curve analysis showed that H-FABP in the diagnosis of septic myocardial injury (AUC = 0.916) was superior to NT-proBNP (AUC = 0.756) and CK-MB (AUC = 0.675); the AUC of NT-proBNP and CK-MB combined with H-FABP was 0.921, the sensitivity was 82.1%, and the specificity was 88.2%.② Twenty-three patients survived in 28 days, and 35 died. The levels of serum PCT, CRP, NT-proBNP, CK-MB, cTnI, H-FABP and APACHEⅡ score in death group were significantly higher than those in survival group [PCT (μg/L): 3.86±1.27 vs. 2.84±1.24, CRP (mg/L): 92.3 (65.0, 101.7) vs. 74.3 (65.7, 79.8), NT-proBNP (ng/L): 9 106.4±2 013.9 vs. 6 975.5±2 266.7, CK-MB (U/L): 17.90±6.49 vs. 12.82±4.46, cTnI (μg/L): 2.11±0.86 vs. 1.12±0.44, H-FABP (μg/L): 30.08±7.90 vs. 20.93±5.14, APACHEⅡ score: 25.0 (20.0, 30.0) vs. 19.0 (17.0, 24.0), all P < 0.01]. ROC curve analysis showed that H-FABP in evaluating 28-day death of patients with septic myocardial injury (AUC = 0.839) was superior to PCT (AUC = 0.707), CRP (AUC = 0.716), NT-proBNP (AUC = 0.761), CK-MB (AUC = 0.733), cTnI (AUC = 0.824) and APACHEⅡ score (AUC = 0.724); the AUC of NT-proBNP and cTnI combined with H-FABP was 0.888, the sensitivity was 91.4%, and the specificity was 82.6%. Conclusions:H-FABP plays an important role in the early diagnosis and prognosis of septic myocardial injury. Early combined detection of NT-proBNP, CK-MB and H-FABP can significantly improve the diagnostic ability of septic myocardial injury, and NT-proBNP and cTnI combined with H-FABP can significantly improve the ability to predict the adverse prognosis of sepsis myocardial injury.

This study was aimed to generalize the therapeutic rules in“Bentun qi” disease treatment through data mining, in order to show a general picture of“Bentun qi” disease by ancient physicians. Furthermore, it was aimed to reveal the nature of“Bentun qi” disease. Frequency statistics, factor analysis and association rules wereused to summarize the therapeutic rules of“Bentun qi” disease by data mining of therapeutic rules from ancient prescriptions. And then, the etiology and pathogenesis of“Bentun qi” disease were deduced. The results showed that besidesyang deficiency and cold accumulation, pathogenic fire derived from liver-qi stagnation, and drink dynamic due toyang deficiency,“Bentun qi” disease also had the etiology and pathogenesis ofqi stagnation and blood stasis due to depression of the liver-qi, blood stasis and cold stagnation due toyang deficiency, qi stagnation in the middle-jiao, and centralqi deficiency and so on. In addition, the herbs in these ancient prescriptions also related to five internal organs. It was concluded that based on theNan Jing(The Classic of Difficult Issues) andJin-Gui Yao-Lue(Essentials from the Golden Cabinet), the knowledge of“Bentun qi” disease began to show a diversity trend after theHanDynasty.

Objective To investigate the variation of the chromosomal karyotype of patients with congenital pseudarthrosis of the tibia(CPT) and its relation with the neurofibromatosis. Methods Ten patients with complete follow up records in 28 cases of CPT treated between 1982 and 1999 were included in this study. There were 7 males and 3 females. The age of the patients at the surgery ranged 4 to 17 years. Seven patients had skin caf?-au-lait spots. Peripheral venous blood (1-2 ml) of 10 patients was cultured in 1640 culture medium with 10%(v/v) fetal calf serum and phytahematoagglutinin(PHA) for 70-72 hours, and then colchicines was added (10 ?g/ml) in culture medium 4 hours before finishing the culture. The specimens were harvested and the chromosomal karyotype was analysed. Results The karyotype of the chromosomes were normal(46XY or 46XX) in all of the speciments, there were no chromosome aberration, chromosome loss and polyploid. Conclusion Neurofibromatosis has no relation with CPT, the genic location of the CPT may have some relation with the neurofibromatosis.
