Journal of Chinese Physician 2013;15(10):1353-1357
Objective To explore the serum lactic acid,transaminase and their relationship with liver pathological damage in sepsis rats,whether a correlation exists between serum lactate clearance rate and transaminase in sepsis rats,and whether they can be used as indicators for the prediction and evaluation of septic rats liver injury.Methods A total of 150 clean Sprague-Dawley (SD) rats was divided into normal group (n =50),sham operated group (n =50),and the cecal ligation and puncture (CLP) (n =50).Ten rats were killed after successful surgery at the 6th,12th,24th,48th,and 72nd hour in CLP group,respectively.At each time point,10 normal rats and 10 sham-operated rats were taken as a control in the corresponding time point.The liver tissue was obtained for pathological analysis.The levels of lactate and liver transaminase were detected and the lactate clearance rate was calculated.The levels of lactate and transaminase at each time point were statistically compared.The correlation analysis was performed among serum lactate,transaminase,and liver damage pathological changes.Results The rat hepatocytes in CLP group begin to appear at the 6th hour,and the damage was gradually enhanced at the 12th,24th,and 48th,and up to the worst damage at the 48th time point.The levels of lactate and alanine aminotransferase (ALT)in CLP group at the 12th and 24th hour were significantly elevated compared with the normal and sham operation groups (P <0.05); The level of aspartate aminotransferase (AST) in CLP group at the 6th,12th,24th,48th,and 72nd hour was significantly elevated compared with the normal and sham operation groups (P < 0.05).A positive correlation was found between the levels of ALT and lactate (r =0.766,P <0.05),and a negative correlation was found between lactate clearance rate and ALT (r =-0.712,P <0.05).Conclusions In septic rats,both lactate and lactate clearance rate were correlated with ALT,and they were correlated with liver pathological damage.The level of lactate,lactate clearance rate,and ALT could be used as the key indicators to predict liver damage in septic rats.

Chinese Critical Care Medicine 2017;29(4):321-326
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.

10.Expression and role of SPARCL1 gene in tumor
Journal of International Oncology 2016;43(9):673-675
Abnormal expression of secreted protein acidic and rich in cysteine like 1 (SPARCL1 )gene is closely related to the development,metastasis and prognosis of a variety of tumors.Recent studies show that SPARCL1 gene is high expressed in glioma.The protein product of SPARCL1 gene encoded can interact with collagen,thus affecting the metastasis ability of tumor,which is positively correlated with tumor malignant de-gree.SPARCL1 gene is low expressed in gastric cancer,colorectal cancer,prostate cancer and breast cancer, which is negatively correlated with the invasion and metastasis abilities of tumors.At present,the role of speci-fic molecular mechanisms of SPARCL1 gene remains controversial. The expressions and functions of SPARCL1 gene in tumor tissues seem to depend on the tumor microenvironment.
