Objectives To investigate the dynamic change of galectin-1 in myocardium of mice with viral myocarditis (VMC). Methods A total of 58 male BALB/c mice were selected and randomly divided into CVB3 group (n=50) and control group (n=8). Mice in CVB3 group were infected with 0.10 ml 10-5/L CVB3 through intraperitoneal inoculation, and 8 mice were killed on day 7, 10, 14 and 28 respectively after inoculation. Mice in control group inoculated with 0.10 ml eagle reagent was killed on day 28. The myocardial pathological changes were observed using light microscope. In addition, expressions of serum galectin-1 were detected by ELISA and expressions of myocardial galectin-1 were detected by real-time quantitative-polymerase chain reaction (RQ-PCR). Results Compared with control group, the myocardial expression of galectin-1 mRNA in CVB3 group was obviously increased on day 7 and day 10 (all P<0.05);the serum concentration of galectin-1 in CVB3 group was obviously increased on day 7, day 10 and day 14 (all P<0.05). Conclusion The expressions of galectin-1 in myocardium of mice with viral myocarditis were in dynamic changes. Galectin-1 may play a role in the pathogenesis and development of viral myocarditis.

The expression of sTK1 in the effective group and in the ineffective group after treatment was significantlycorrelated with CRP (P < 0.05). Conclusion sTK1 can be used as a valuable indicator to evaluate the severity of AECOPD and to estimate the efficacy of AECOPD thera-py.

Objective To analyze the characteristics of change in plasma cholesterol level in patients with sepsis, and to explore its relationship with prognosis and its clinical significance. Methods A retrospective analysis was conducted. 568 patients with sepsis admitted to Department of Critical Care Medicine of Beijing Friendship Hospital Affiliated to Capital Medical University from August 2013 to August 2015 were enrolled, and 475 patients without sepsis hospitalized in the same period served as the control. The basic clinical data of the two groups were collected, and the results of blood fat and biochemical parameters were compared. The patients with sepsis were divided into death group and survival group, and risk factors influencing the prognosis of patients with sepsis were analyzed with multivariate logistic model regression analysis. Results Compared with non-sepsis patients, the levels of plasma total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) in the patients with sepsis were significantly lower [TC (mmol/L): 2.5±1.2 vs. 3.4±1.4, t = 4.274, P = 0.021; HDL-C (mmol/L): 1.6±0.9 vs. 2.5±0.8, t = 3.413, P = 0.018], and that of low density lipoprotein cholesterol (LDL-C) showed no statistically significant difference (mmol/L: 1.9±0.9 vs. 2.1±0.9, t = 0.749, P = 0.614). In the patients with sepsis, the patients in death group (n = 227) were older than those of the survival group (n = 341, years: 74.3±15.5 vs. 65.5±17.5, t = 4.037, P = 0.012), serum creatinine (SCr) was higher than that of survival group (μmol/L: 251.0±115.6 vs. 167.4±108.7, t = 3.254, P = 0.023), the levels of plasma TC, HDL-C and LDL-C were significantly lower than those of survival group [TC (mmol/L): 2.2±1.6 vs. 2.9±1.1, t = 3.057, P = 0.023; HDL-C (mmol/L): 1.4±0.8 vs. 1.9±0.8, t = 4.692, P = 0.016; LDL-C (mmol/L): 1.7±0.7 vs. 2.0±0.8, t = 2.541, P = 0.038]; there was no significant difference in the proportion of male, body mass index (BMI), based disease, intensive care unit (ICU) hospitalization time, the severity of the disease and other biochemical indexes between two groups. With single factor analysis with indicators of statistical significance as a covariate into binary logistic regression equation, the results show that age was the risk factor of death in patients with sepsis [odds ratio (OR) = 1.024, 95% confidence interval (95%CI) = 1.010-1.048, P = 0.009], and TC was the protective factor on the prognosis of patients with sepsis (OR = 0.747, 95%CI = 0.682-0.811, P = 0.013). Conclusions Plasma cholesterol levels in patients with sepsis were significantly lowered, and the levels in death group was significantly lower than that in the survival group. TC may be used as a clinical indicator to assess the outcome of patients with sepsis.

Aim To investigate the effect of astragalo-side IV ( ASIV) on myocardial energy metabolism and mitochondrial biosynthesis in myocardial cells of dia-betic rats induced by streptozotocin ( STZ ) . Methods
50 SD rats at 6 weeks of age were assigned to 5 groups,10 for each group:control group, model group, ASIV 10 mg·kg-1 ·d-1 group, ASIV 20 mg·kg-1 ·d-1 group, ASIV 40 mg·kg-1 ·d-1 group. Except the control group,the remaining 40 were used to estab-lish type 1 diabetes model by the tail vein injection of STZ (35 mg·kg-1 ) . At the end of 16 weeks of treat-ment, left ventricular systolic pressure ( LVSP ) , left ventricular diastolic final pressure ( LVEDP ) and left ventricular maximum rising/falling rate ( ± dp/dtmax ) were tested. Pathological section was observed by HE staining. ATP, ADP, AMP levels were detected by ELISA. The expressions of PGC-1α and NRF-1 protein were assessed by Western blot. The expressions of PGC-1α and NRF-1 mRNA were determined by RT-PCR. Results Compared with control group, model group markedly elevated LVEDP and decreased LVSP, ± dp/dtmax , ATP/AMP and ATP/ADP ratio. Com-pared with model group, low-dose ASIV group did not change significantly,middle-dose ASIV group and high-dose ASIV group obviously decreased LVEDP, and im-proved LVSP, ± dp/dtmax , ATP/ADP and ATP/AMP ratio. Meanwhile, the expressions of PGC-1α and NRF-1 protein and mRNA were increased in a dose-de-pendent manner. Conclusion ASIV could promote mitochondrial biosynthesis, improve energy metabolism in myocardial cells of type 1 diabetic rats by PGC-1αand NRF-1 .
