Objective To investigate the relationship between plasma low-density lipoprotein (LDL) levels and hematoma enlargement of early intracerebral hemorrhage,outcome at 3 months and death.Methods A total of 316 patients with primary intracerebral hemorrhage were included in the study.Their general information was documented.The patients underwent CT scans at 6 and 24 hours after onset.The lipids,blood glucose,blood pressure,and the National Institutes of Health Stroke Scale (NIHSS) scores were detected at the same time.The patients were followed up for 3 months and their modified Rankin scale (mRS) scores and the number of death were recorded.Results The decreased plasma LDL level (odds ratio [OR] 0.323,95％ confidence interval [CI] 0.128 - 0.819; P =0.017) and the increased systolic pressure (OR 1.015,95％ CI 1.000 -1.029; P =0.043) were independently associated with the early hematoma enlargement.The decreased plasma LDL level (OR 0.253,95％ CI 0.102-0.629; P=0.003) and the increased blood glucose (OR 1.458,95％ CI 1.257 - 1.693; P ＜ 0.001 ) were the independent risk factors for poor outcome at 3 months after onset.The decreased plasma LDL level (OR 0.211,95％ CI 0.075 - 0.597; P =0.003),the increased bloot glucose level (OR 1.406,95％ CI 1.212 - 1.632; P =0.001) and the increased blood glucose level (OR 1.026,95％ CI 1.009 - 1.043; P =0.002) were the independent risk factors for death within 3 months.Receiver operating characteristic curves showed that the LDL level ＜ 2.58 mmol/L was an independent predictor for hematoma enlargement (sensitivity 71.79％,specificity 64.71％,positive predictive value 40.00％,and negative predictive value 87.50％ ).Conclusion The decreased plasma LDL level was the independent predictor for early hematoma enlargement,poor outcome and death at 3 months in patients with primary intracerebral hemorrhage.

Objective To develop an un_fluorescent staining method in Comet Assay. Methods Some special un_fluorescent DNA staining methods, Feulgen, Methyl Green, Stains_all and Silver_Stain were tested in Comet Assay and the comparison studies with EB stain were carried out. Results Among the stain methods tested, just the silver_stain could give a satisfactory effect: legible, ease to judge the stained area of the comets head and tail, permanent, sensitive, could make little segment of DNA be stained, which couldnt be stained by EB stain, the length of comets head and tail, were over 2 times of that of EB stain, safety and economical. Conclusion The silver_stain method discarded the defects of EB stain, so that it could replace EB stain and make comet assay possible to be extended.

Objective To investigate the clinical value of serum endocan and procalcitonin (PCT) in early diagnosis and prognosis evaluation of sepsis.Methods The patients with systemic inflammatory response syndrome (SIRS,n = 26) and sepsis (n = 78) admitted to intensive care unit (ICU) of the Third Hospital of Hebei Medical University from December 2014 to December 2016 were enrolled. According to the severity of disease, the sepsis patients were divided into general sepsis group (n = 20), severe sepsis group (n = 24), and septic shock group (n = 34). The cases were divided into survival group (n = 55) and non-survival group (n = 23) according to 28-day mortality. The serum endocan, PCT, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, and sequential organ failure assessment (SOFA) score were recorded when the patients were admitted into ICU. The differences in endocan, PCT, APACHE Ⅱ, SOFA score between SIRS and sepsis groups and within sepsis subgroups were compared. Spearman correlation analysis was used to analyze the correlation between the indexes of sepsis patients. Receiver operation characteristic curve (ROC) was used to evaluate the value of endocan and PCT for the diagnosis and prognosis of sepsis.Results ① Serum endocan, PCT, APACHE Ⅱ, SOFA score and 28-day mortality in the sepsis group were significantly higher than those in the SIRS group [endocan (μg/L): 4.28 (10.64) vs. 1.03 (0.69), PCT (μg/L): 3.94 (10.75) vs. 0.43 (0.39), APACHE Ⅱ:18.81±9.17 vs. 9.35±3.78, SOFA: 9.00 (7.20) vs. 4.50 (1.50), 28-day mortality: 29.49% vs. 11.54%, allP < 0.01]. The area under the ROC curve (AUC) of endocan, PCT, APACHE Ⅱ, SOFA score for sepsis diagnosis were 0.887, 0.842, 0.822, 0.835, respectively. When the cut-off value of endocan was 1.26μg/L, the sepsis diagnostic sensitivity was 87.2% and specificity was 81.8%. When the cut-off value of PCT was 0.75μg/L, the sepsis diagnostic sensitivity was 85.9% and specificity was 81.8%. ② With the severity of the disease increased, the index showed an increasing trend in patients with sepsis. Serum endocan, PCT, APACHE Ⅱ, SOFA score and 28-day mortality in septic shock group were significantly higher than those in severe sepsis group or general sepsis group [endocan (μg/L): 13.02 (6.70) vs. 3.33 (3.05), 1.60 (0.98); PCT (μg/L): 8.10 (17.68) vs. 5.47 (8.92), 1.57 (2.78); APACHE Ⅱ: 25.00 (9.50) vs. 18.00 (9.00), 9.50 (5.75); SOFA: 13.00 (4.50) vs. 8.00 (3.00), 5.00 (3.50); 28-day mortality: 52.94% vs. 20.83%, 0%; allP < 0.01]. There was a significantly positive correlation between endocan, PCT, APACHE Ⅱ, SOFA, indicating that the endocan and PCT can be used to assess the severity of sepsis. ③ Serum endocan, PCT, APACHE Ⅱ and SOFA score in non-survival group were significantly higher than those in the survival group [endocan (μg/L): 15.05 (9.23) vs. 2.32 (4.81), PCT (μg/L):18.40 (16.99) vs. 3.10 (6.67), APACHE Ⅱ: 28.13±7.56 vs. 14.91±6.64, SOFA: 14.70±3.65 vs. 7.38±3.26, allP < 0.01]. The AUC of endocan, PCT, APACHE Ⅱ, SOFA score for the prediction of non-survival sepsis were 0.915, 0.763, 0.899, 0.930. When the cut-off value of endocan was 4.37μg/L, the septic death prediction sensitivity was 95.7% and specificity was 70.9%. When the cut-off value of PCT was 7.68μg/L, the septic death prediction sensitivity was 65.2% and specificity was 78.2%.Conclusions Serum endocan is more clinically valuable than PCT in early diagnosis and prognosis assessment of sepsis.
