ABSTRACT
ObjectiveTo investigate the effects of budesonide inhaled on the levels of interleukin-8 (IL-8), C-reactive protein (CRP) and procalcitonin (PCT) in bronchoalveolar lavage fluid (BALF) of patients with AECOPD treated by using inhalation of budesonide in different doses or by using injection of dexamethasone. MethodsNinety AECOPD patients with mechanical ventilation in ICU ward were enrolled from Jan. 2008 through Sep. 2010. All patients were selected in this study as per the criteria of AECOPD set by the Chinese Medical Association. Ninety AECOPD patients treated with routine therapy were randomly (random number) divided into 3 groups. The patients of group A were given budesonide 2 mg inhaled 1 time/d. The patients of group B was given budesonide 4 mg inhaled 1 time/d. The patients of group C had dexamethasone 2. 5 mg injected 1 time/12h. The changes of IL-8, PCT and CRP in both BALF and serum were respectively detected in three groups at the beginning of treatment, and 3 days and 7days after treatment. The detected data of variables were analyzed by SPSS 13.0 package. ResultsThe level of IL-8 in BALF declined in 3days and 7days after treatment, and the magnitude of decrease in the following order:Group B ( budesonide 4mg/d) ＞ Group A ( budesonide 2 mg/d) ＞ Group C ( intravenous dexamethasone)with significant differences among them ( P ＜ 0. 05 ). The decrease in IL-8 in serum showed the similar trend, but there were no statistical differences among them. The CRP and PCT in both BALF and serum had no significant changes. There was a correlation between the concentration of IL-8 in BALF and the duration of mechanical ventilation.Conclusions The treatment with the inhalation of budesonide could more significantly reduced the IL-8 level in BALF compared with intravenous dexamethasone, whereas the CRP and PCT were not changed. The dynamic changes of IL-8 in BALF might be used as an indicator of prognosis in AECOPD patients with mechanical ventilation.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Xuebijing injection on serum protein level in the early phase of septic rats and explain the mechanism from the perspective of molecular biology.</p><p><b>METHOD</b>Fifty-four healthy wistar rats were randomly divided into control group, sepsis group and Xuebijing treatment group. The rat model of sepsis was established with injecting lipopolysaccharide (LPS) through caudal vein. Serum total protein (TP) and albumin (ALB) were measured at the point of 6, 12 and 24 h with the established model. The expression of AMPK, eEF2 protein in liver in the three groups were detected by Western blot analysis.</p><p><b>RESULT</b>Compared with control gruop, the concentrations of TP and ALB of sepsis group and Xuebijing group were no significant difference with 6, 12 h treatment TP and ALB in sepsis group was lower (P<0.01) than control group after 24 h, and the expression of phos-AMPK, pho-eEF2 protein in livers was increased (P<0.01) simultaneously. All measured indexes in Xuebijing group has no difference with control group. Compared with sepsis group, TP and ALB of Xuebijing group was significantly higher (P<0.05), but litle lower than control group, the expression of phos-AMPK, pho-eEF2 protein in livers was decreased (P<0.05) simultaneously.</p><p><b>CONCLUSION</b>These data suggest that Xuebijing injection prohibits catabolising serum albumin and inhibit liver protein catabolism by method of AMPK way.</p>

Objective To study the MRI signs of primary central nervous system lymphoma(PCNSL).Methods MRI features of PCNSL in 44 patients proven by pathology from January 2004 to September 2005 were analysed retrospectively.There were 29 men and 15 women,the age ranged from 12~76 years old with mean 53.Results The lesions localized at brain in 41 patients and spinal cord in 3.The lesions were multiple and single.The lesions were hypointense on T1WI and isointense or hyperintense on T2WI mostly.Nearlly all the lesions had parenchymatously massive or nodular enhancement,the minority has ring-like enhancement post contrast-enhanced scan.Conclusion PCNSL has certain MRI characteristic.The solitary or multiple lesions with obviously nodular enhancement,especial contact with cerebrospinal fluid space,the possibility of PCNSL diagnosis should be consider.
