RESUMEN

Forests influence climate through both the biochemical and biophysical processes, and the impacts of the latter on local climate may be much larger than the former. However, the biophysical effects of afforestation in arid regions have received little attention compared with afforestation in the tropic, temperate and boreal zones. In this study, we combined in situ eddy covariance flux measurements from a neighboring pairs of forested and background desert sites with the decomposed temperature metric (DTM) method to characterize the impacts of arid forests on surface temperature (Ts). A clear-sky, one-dimensional planetary boundary layer (PBL) model was used to estimate the impacts of afforestation on state of regional climate. We showed that despite absorbing more net radiation (35.4 W m-2) the riparian forests tended to cool Ts (-1.28 °C) on annual basis, but with a significant seasonality. Specifically, afforestation may lead to a net cooling effect from March to September and a slightly warming effect in other months. The DTM method revealed that evapotranspiration played a dominant role in cooling surface temperature, while surface albedo (α) and incoming longwave radiation (L↓) acted together to increase forest surface temperature. From June to September, a shallower, cooler and wetter boundary layer was developed over the forest due to high plant transpiration. In other months, the PBL was slightly deeper and warmer over the forest than that over the desert. Therefore, the riparian forests were important in moderating warming trends in arid regions.

METHODS :By equilibrium dialysis ,LGT-6(3,30,300,3 000 nmol/L)was equilibrated in rat ,monkey and human plasma (i. e. internal dialysis solution )for 48 h,using phosphate buffer as the external dialysis solution. The concentration of LGT- 6 in internal and external dialysis solution was determined by UPLC-MS/MS using tolbutamide as internal standard ,and the plasma protein binding rate was calculated. The determination was performed on ACQUITY UPLC HSS T 3 column with water (containing 0.01% formic acid )-acetonitrile(containing 0.01% formic acid )as mobile phase at the flow rate of 0.6 mL/min. The column temperature was 40 ℃,and the sample size was 2 μL. The ion source was electrospray ion source ,and the multiple ion monitoring mode was used to carry out positive ionization scanning. The ion pairs for quantitative analysis were m/z 487.0→434.3(LGT-6),m/z 271.1→172.0(internal standard ),respectively. RESULTS :At the concentrations of 3,30,300,and 3 000 nmol/L,the protein binding rates of LGT- 6 in rat plasma were (96.25±0.97)%,(84.16± 1.24)%,(78.25±0.61)%,(66.63±0.95)%;the protein protein binding rates in monkey plasma were (98.54±0.58)%,(87.27± 1.01)%,(79.35±0.86)%,(66.69±0.54)%;the protein binding rates in human plasma were (99.40±1.03)%,(84.48± 1.15)%,(77.62±0.77)%,(66.93±0.48)%. At the same concentration ,the protein binding rates of LGT- 6 in rat ,monkey and human plasma had no significant difference (P>0.05). In the same species of plasma ,there were significant differences in the plasma protein binding rates of different concentration of LGT-6 among those groups (P<0.05),and it decreased with 才〔2016〕4015) the increase of drug concentration. CONCLUSIONS : The method for the determination of plasma protein binding rate of LGT-6 is successfully established. The data revealed that the protein binding rate of LGT- 6 is concentration-dependent , there was no obvious spec ies difference on protein binding rates of LGT- 6 in rat ,monkey and human plasma under the same concentration.

RESUMEN

OBJECTIVE: To establish a determination method for the concentration of cajanonic acid A (CAA) in liver microsome incubation system, and to compare the metabolism characteristics of it in different species of liver microsomes. METHODS: CAA was dissolved in liver microsome incubation system of rat, Beagle dog and human initiated by reduced nicotinamide adenine dinucleotide phosphate (NADPH), and was incubated in water at 37 ℃. The reaction was terminated with acetonitrile at 0, 5, 10, 15, 30, 45 and 60 min, respectively. Using genistein as internal standard, the concentration of CAA in  different incubation systems was determined by UPLC-MS/MS. The determination was performed on Waters BEH C18 column with mobile phase consisted of water (containing 0.1% formic acid)-acetonitrile (containing 0.1% formic acid) (45 ∶ 55, V/V) at the flow rate of 0.25 mL/min. The column temperature was 30 ℃, and the sample size was 2 μL. The electrospray ionization source was used to the select reaction monitoring mode for negative ion scanning. The ion pairs for quantitative analysis were m/z 353.14→309.11 (CAA), m/z 269.86→224.11 (internal standard) respectively. The residual percentage and enzymatic kinetic parameters of CAA in different incubation systems were calculated according to the mass concentration of CAA at 0 min. RESULTS: The linear range of CAA was 0.05-20 μg/mL; the limit of quanti- tation was 0.05 μg/mL, and the lowest detection limit was 0.01 μg/mL. RSDs of intra-day and inter-day were lower than 10%; relative errors ranged -4.83%-8.94%; extraction method and matrix effect did not affect the determination of the substance to be measured. At 60 min of incubation, residual percentages of CAA in rat, Beagle dog and human liver microsomes were(62.79±9.99)%,(64.07±11.59)%,(96.66±5.71)%, respectively. The half-life period (72.19, 68.61 min) of CAA in rat and Beagle dog liver microsomes were significantly shorter than human liver microsome (364.74 min). The clearance rates [0.019 2, 0.020 2 mL/(min·mg)] were significantly higher than human liver microsome [0.003 8 mL/(min·mg)] (P<0.05). CONCLUSIONS: Established UPLC-MS/MS method is simple, rapid, specific and sensitive, and can be used for the determination of CAA concentration in liver microsome incubation system and the study of metabolism stability in vitro. The stability of CAA metabolism in rat and Beagle dog liver microsomes are poorer than human liver microsome.

Objective To investigate the clinical value of the ratio of plasma vascular endothelial growth factor level to platelet count (VEGF/PLT) in predicting 28-day prognosis in patients with sepsis.Methods A prospective cohort study was conducted.From September 2009 to March 2013,164 sepsis patients in Intensive Care Unit (ICU) of Guangdong General Hospital were included for study.Patients with age younger than 18 years old,the illness already reaching final stage of chronic diseases,suffering from two or more organs dysfunction within 3 days,acute pancreatitis without infection,or less than 28 days of expected survival time were excluded.Finally,135 patients were included in the further analysis.Peripheral blood samples were collected at admission.Routine blood tests were done,and then VEGF levels in plasma were measured by enzyme linked immunosorbent assay (ELISA).Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores were recorded every day for 7 days.Patients' prognosis was assessed during the following 28 days.The patients were divided into 28-day survival group and non-survival group.Comparison between two groups was done by single factor analysis.Spearman rank correlation was used to analyze the correlation between VEGF levels and PLT.Mutivariate logistic regression analysis was performed to identify the independent risk factor for 28-day prognosis.Receiver operating characteristic curve (ROC curve) was plotted,and the effect of related indexes on predicting 28-day survival was evaluated by area under ROC curve (AUC).Results There were no significant differences in VEGF (ng/L:471.73 ± 198.34 vs.383.49 ± 266.54,t=-1.918,P=0.057),PLT (× 109/L:220.40±127.60 vs.246.42± 100.72,t=1.275,P=0.204),leucocyte counts (× 109/L:12.48 ±4.62 vs.13.70 ±5.97,t=1.063,P=0.292),mean arterial pressure [mmHg (1 mmHg=0.133 kPa):86.50 ± 12.04 vs.91.03 t 13.10,t=1.557,P=0.123] and blood lactic acid (mmol/L:1.79 ± 1.30 vs.1.50 ± 0.60,t=-1.768,P=0.079) at admission between the non-survival group (n=42) and survival group (n=93).VEGF/PLT (2.59 ± 1.44 vs.1.73 ± 1.13,t=-3.756,P=0.000) as well as APACHE Ⅱ scores (15.50 ± 4.50 vs.13.28 ± 4.61,t =-2.022,P=0.045) of the non-survival group were significantly higher than those of survival group,and oxygenation index (PaO2/FiO2) of the non-survival group was significantly lower than that of survival group (kPa:32.38 ± 11.12 vs.37.04 ± 10.97,t=2.278,P=0.024).Correlation analysis showed that the concentration of VEGF was positively correlated with PLT (r=0.271,P=0.001).It was shown by multivariate logistic regression analysis that only VEGF/PLT was the independent risk factor in predicting 28-day prognosis in patients with sepsis [odds ratio (OR) was 1.591,95% confidence interval (95%CI) 1.164-2.175,P=0.004].AUC of VEGF/PLT was 0.704 ± 0.047 (P=0.000,95%CI:0.611-0.797) for predicting 28-day survival.The optimal cut-off point was 1.32,and the sensitivity and specificity were 81.0% and 48.4%,respectively.Conclusion VEGF/PLT can be used as one of the indicators to predict 28-day survival in patients with sepsis.

RESUMEN

Objective To investigate the characteristic changes in cerebral infarction and brain edema. Method A total of 122 Healthy adult male Spraque-Dawley rats were randomly (random number) divided into three groups: normal group ( n = 12), sham operated group (n=12) and cerebral ischemia group ( n = 98). Cerebral infarction and brain edema were induced by a permanent occlusion of right middle cerebral artery (POM-CA) with ligature. According to the duration of POMCA, the rats of cerebral ischemia group were further divided into seven sub-groups, 2 h, 4 h, 6 h, 12 h, 18 h, 24 h and 30 hours. The hemispheric ratio was detected by staining with 2% 2,3,5-triphenyltetrazolium chloride solution, and brain water content was assayed by dry/wet ratio 2 h, 4 h, 6 h, 12 h, 18 h, 24 h and hours after POMCA. Results There was a focal cerebral infarction in the rats of cerebral ischemia group 4 hours after POMCA. There was no significant difference in hemispheric ratio between 4 hours and 6 hours after POMCA by One-way ANOVA (P = 0.091). Compared with 6 h sub-group, the hemispheric ratio increased significantly in 12 h, 18 h, 24 h and 30 h sub-groups (P < 0.01), and the peak was in the 24 h sub-group. The brain water content began to increase 4 hours after POMCA and aggravated 6 hours later, and reached the peak 24 hours after POMCA. The brain water content of the non-ischemic hemisphere increased 18 h,24 h and 30 hours after POMCA. Furthermore, there was a significant correlation between the hemispheric ratio and brain water content ( r = 0.834, P < 0.01). Conclusions The critical point of cerebral infarction and brain edema aggravated is 6 hours after POMCA. Both brain edema and cerebral infarction reach the most serious degree 24 hours after POMCA. It is an important experimental evidence for evaluating the milieu conducive to the pathogenesis, and choosing the suitable time window for the treatment of cerebral infarction and brain edema.
