Objective:To explore the risk factors of delayed traumatic intracranial hematoma (DTICH)followed by unilateral large decompressive craniectomy (LDC)and its influence in the prognosis of the severe traumatic brain injury (sTBI)patients,and to improve the successful rate of the rescue.Methods:The clinical data of 130 sTBI patients underwent unilateral LDC were retrospectively analyzed.The patients were divided into DTICH group (n=42)and non-DTICH group (n=88)according to whether the DTICH occurred after operation.The risk factors of DTICH and its influence were contrastively analyzed.Results:The analysis results of the clinical data of patients in two groups showed that preoperative GCS,time from trauma to operation,skull fracture,midline shift > 1 cm, basal cistern disappear,activated partial prothrombin time (APTT),fibrinogen (FIB),and thrombin time (TT) were significantly correlated with the appearance of DTICH (P<0.05).Multivariable Logistic regression analysis showed that the time from trauma to operation, skull fracture, basal cistern disappearing and FIB were the independent risk factors of DTICH (P<0.05).The analysis results of GOS 3 months after operation of the patients in two groups showed that the prognosis of the patients in DTICH group was significantly worse than that in non-DTICH group (P<0.01 ).Conclusion:For those patients who accompanied with shorter time from trauma to operation,skull fracture,basal cistern disappearing and FIB decrease,the appearance of DTICH should be paid attention.DTICH can affect the prognosis of patients;prevention and early diagnosis are crucial to improve the prognosis of patients.

[Objective] To explore the methods of avoiding hemolysis in preparing serum complements of guinea pigs. [Methods] In method 1, the serum of 8 guinea pigs was fixed first and then sheep red blood cells (SRBC) were added to the mixed serum for absorption. In method 2, SRBC was added to the serum of 8 guinea pigs respectively for absorption first and then the serum containing SRBC was mixed. After the experiment, macroscopic examination was carried out to observe the hemolysis and the optical density of the two kinds of mixture was detected at the wavelength of 540 nm. [ Results] In the serum complements of guinea pigs prepared by method 1, macroscopic hemolysis occurred; in the serum complements prepared by method 2, macroscopic hemolysis was not obvious and the optical density of the mixture was lower than that by method 1 ( P

In the context of Popular Entrepreneurship and Innovation, scientific and systemic implementation of innovation and entrepreneurship education is the focus of higher education reform at present. This paper analyzes the important significances of carrying out innovation and entrepreneurship education in higher education of traditional Chinese Medicine, introduces the specific practices and experi-ences of designing educational concept and constructing education system about innovation and entrepre-neurship education, following the objective laws of modern educational development and the growth pattern of Chinese medicine talents, in order to provide reference for further promoting innovation and entrepreneu-rship education reform.

Objective:To investigate the diagnostic values of interleukin-22 (IL-22), interferon-γ(IFN-γ)and macrophage migration inhibition factor (MIF) in pleural effusion for tuberculosis pleurisy.Methods:From April 2018 to May 2019, a total of 77 patients including 45 cases of tuberculous pleurisy, 19 cases of malignant pleurisy, 13 cases of parapneumonia and 13 cases of healthy control in Wuxi Fifth People′s Hospital were enrolled. The levels of IL-22, IFN-γ and MIF in plasma and pleural effusion were detected by enzyme linked immunosorbent assay (ELISA). Mann-Whitney U test was used for statistical analysis.The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic values of IL-22, IFN-γ and MIF for tuberculous pleurisy. Results:The median levels of IL-22, IFN-γ, MIF and adenosine deaminase in 45 cases with pleural effusion in tuberculosis pleurisy group were 396.8 ng/L, 2 200.0 ng/L, 241.3 μg/L and 70.8 U/L, respectively, which were all significantly higher than 32 cases with non-tuberculosis pleurisy group, including 19 cases with malignant pleurisy and 13 cases with parapneumonia (52.8 ng/L, 232.3 ng/L, 179.6 μg/L and 17.0 U/L, respectively). The differences were all statistically significant ( U=179.000, 118.500, 287.000, 162.000, respectively, all P<0.05). The median levels of IL-22 and IFN-γ in plasma of tuberculosis pleurisy group were 20.0 ng/L and 45.9 ng/L, respectively, which were both higher than healthy control group (14.3 ng/L and 33.4 ng/L, respectively). The level of MIF was 96.2 μg/L, which was lower than healthy control (159.5 μg/L). The differences were all statistically significant ( U=74.000, 13.000 and 73.000, respectively, all P<0.05). The areas under ROC curve (AUC) of IL-22, IFN-γ and MIF in pleural effusion for the diagnosis of tuberculosis pleurisy were 0.876, 0.917 and 0.682, respectively.The sensitivities were 93.75%, 100.00% and 63.64%, respectively; the specificities were 82.22%, 91.11% and 65.85%, respectively. The median levels of IL-22 and IFN-γ in plasma in tuberculosis pleurisy group at two months of follow-up after anti-tuberculosis therapy were 16.0 ng/L and 33.9 ng/L, respectively, which were both lower than baseline (20.0 ng/L and 44.7 ng/L, respectively). The differences were both statistically significant ( U=2.156 and 2.221, respectively, both P<0.05). Conclusion:IFN-γ and IL-22 in pleural effusion could be used as effective indicators to identify tuberculous pleurisy, and the dynamic monitoring of IL-22 in patients′plasma could be an important biomarker in evaluating the efficacy of anti-tuberculosis treatment.

Objective:To investigate the relationship between indicators of carotid atherosclerosis and onset of ischemic stroke in patients with non-valvular atrial fibrillation (NVAF).Methods:This is a case-control study, a total of 397 NVAF patients with newly diagnosed ischemic stroke (case group) and 3 038 NVAF patients without ischemic stroke (control group) from January 2015 to December 2017 were included in the study. Differences in general clinical features and carotid atherosclerosis indexes between the two groups were compared. Univariate and multivariate logistic regressions were used to analyze the correlation between carotid atherosclerosis indexes and ischemic stroke.Results:Proportions of patients with carotid intima thickening, carotid plaque, stable plaque, unstable plaque, and moderate to severe stenosis were higher in the ischemic stroke group than those in the control group (82.1% vs. 64.4%, 69.3% vs. 50.3%, 43.6% vs. 30.6%, 25.7% vs. 19.7%, and 7.3% vs. 4.0%, respectively, all P <0.05). After adjustment of age, gender, heart failure, hypertension, low density lipoprotein -cholesterol and drug use, multivariate analyses showed that subjects with carotid intima thickening, carotid plaque, stable plaque, unstable plaque, moderate to severe stenosis had 1.766, 2.111, 1.892, 2.256 and 1.824 times the risk for the development of ischemic stroke compared with the subjects without any carotid atherosclerosis indicators. Conclusion:Carotid atherosclerosis, especially with unstable carotid plaque, is associated with ischemic stroke in patients with NVAF.
