Objective To analyze the effect of Shuxuetong injection on microcirculation in patients with septic shock and its therapeutic effect. Methods A prospective study was conducted. Eighty patients with septic shock treated in Department of Critical Care Medicine of Hebei Provincial Traditional Chinese Medical Hospital were randomly divided into a Shuxuetong group and a conventional therapy group according to random number table, 40 cases in each group. The conventional treatment in the two groups was energetically carried out in accord to the sepsis shock guidelines, such as positive fluid resuscitation, anti-infection, etc. In the Shuxuetong group, additionally Shuxuetong injection 6 mL in 5% glucose injection 250 mL intravenous drip was given once a day for 7 days. The levels of urine output, lactic acid (Lac), blood urea nitrogen (BUN), creatinine (Cr), aspartate aminotransferase (AST), alanine aminotransferase (ALT), left ventricular ejection fraction (LVEF), and cardiac index (CI) in the two groups were observed before and after treatment; the total dosages of dopamine, dobutamine, noradrenaline, etc. vascoactive agent used for the patients and 28-day mortality in the two groups were also recorded. Results The comparisons of levels of urine output, Lac, BUN, Cr, AST, ALT, LVEF, and CI before treatment between the two groups were of no statistical significant differences (all P>0.05). After treatment in the two groups, the urine output, LVEF, and CI were increased compared with those before treatment, whereas the Lac, BUN, Cr, AST, and ALT were significantly decreased, and the changes were more obvious in Shuxuetong group [urine output (mL/h):112.1±39.8 vs. 73.3±28.5, LVEF:0.49±0.15 vs. 0.44±0.14, CI (mL·s-1·m-2):66.2±5.7 vs. 54.2±6.2, Lac (mmol/L):3.83±1.65 vs. 4.72±2.25, BUN (mmol/L):7.1±2.7 vs. 9.3±3.5, Cr (μmol/L): 73.9±16.2 vs. 95.7±15.8, AST (U/L): 39.8±9.5 vs. 45.8±12.7, ALT (U/L):34.3±9.7 vs. 41.7±11.3, all P<0.05]. The total dosages of all kinds of vascoactive agent of Shuxuetong group were remarkably less than those in the conventional therapy group [dopamine (mg): 993.1±261.7 vs. 1 340.9±356.4, dobutamine (mg):776.2±281.0 vs. 1 049.2±364.3, noradrenaline (mg):56.4±34.6 vs. 107.6±51.3, all P<0.05]. The 28-day mortality of Shuxuetong group was obviously lower than that of conventional therapy group [40.0%(16/40) vs. 60.0%(24/40), P<0.05]. Conclusion Shuxuetong injection can improve the microcirculation perfusion in patients with septic shock and reduce their mortality.

Objective To explore the relationship between obesity phenotypes and adipocytokines in children.Methods Based on the Beijing child and adolescent metabolic syndrome (BCAMS) study,3 508 children (1 788 boys and 1 720 girls) aged 6-18 were recruited.In this study,participants were categorized into four groups:226 cases in general obese group,192 cases in abdominal obese group,1 004 cases in combined obese group and 2 086 cases in non-obese group,according to the sex,age,specific body mass index(BMI),and waist circumference (WC) equal to or greater than the 90th percentile for age and gender of school children in Beijing in 2004.The levels of plasma insulin,serum leptin,resistin and adiponectin were measured by sensitive,specific double-antibody sandwich enzyme-linked immunosorbent assays (ELISA).Analysis of covariance,multivariate linear regression and binary logistic regression analysis were performed.Results There were highest plasma insulin and serum leptin,and lowest adiponectin levels in combined obese group than those in other obese groups and non-obese group and resistin level in abdominal obese group was highest than those in other obese groups or non-obese group.Among subjects with general obesity and conbined obesity,WC was more important factor than BMI for plasma insulin[?(WC)=0.158 P0.05].With covariates adjusted,the odds ratios(OR)and 95% confidence intervals of general obesity,abdominal obesity and combined obesity were 3.46(2.44-4.91),5.41(3.87-7.57) and 10.10(8.26-12.35) for predicting hyperinsulinemia,respectively,5.83(4.02-8.45),7.07(4.97-10.05)and 20.82(16.49-26.28) for hyperleptinaemia,respectively,1.47(1.05-2.07),2.0(1.42-2.80) and 2.66(2.23-3.18) for hypoadiponectinaemia,respectively.Serum resistin was highest in abdominal obesity.Conclusion The levels of adipocytokines in children were correlated with the phenotypes of obesity,especially for abdominal obesity.

AIM: To observe effect of the iris location to femtosecond - combined wavefront guided LASIK for myopia and astigmatism.?METHODS:The patients with astigmatism >1. 0D during the same time and followed up for 1a were selected. A total of 129 eyes in 67 patients were treated under iris location with femtosecond-combined wavefront guided LASIK ( experimental group) and 161 eyes in 82 cases with femtosecond-combined wavefront guided LASIK ( control group) . Laser cutting went with the same laser machine. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) , and wavefront aberration between the two groups were compared at 1, 3, 6mo and 1a after surgery.?RESULTS:At 1 and 3mo after surgery, the number of patients with better postoperative UCVA than preoperative BCVA between the two group showed a statistically significant difference (χ2=6. 423, P=0. 011,χ2=14. 431, P=0. 01 ); at 1d and 1mo after surgery, the residual astigmatism showed a statistically significant difference between two groups (t=1. 98, P<0. 05; t=2. 23, P<0. 05). At 3, 6mo and 1a after surgery, the differences on the change of residual astigmatism between the two groups weren’t significant ( P > 0. 05 ). At 6mo and 1a after surgery, the differences on UCVA between the two groups weren’t significant ( P > 0. 05 ). Until 1a after surgery, the root mean square ( RMS ) of high order wavefront aberration of the two groups, spherical aberration and coma aberration ( COMA ) were all enhanced compared to before surgery(P<0. 05). At 1, 3mo after surgery, the RMS showed a statistically significant difference between two groups (P<0. 05). At 1, 3, 6mo, 1a after surgery, the increase of COMA in experimental group was significantly lower than that in control group (P<0. 05).? CONCLUSION: Iris location technology applied in femtosecond - combined wavefront guided LASIK for myopia and astigmatism, can make the vision recovery faster, the RMS of high order and COMA increase less, the residual astigmatism less, show better and more stable treatment effect.
