Results The abnormal rate of EEG was 86.7 % in children with cysticercosis,which mainly showed the diffuse or focal irregularity complex slow waves in frontal lobe,central lobe and anterior lobe.The abnormal rate of CT was 70.8 % in all patients,and flaky and circular focus were chief manifestations.There was a significant difference be- tween the rates of EEG and CT(P

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

Objective： This study was designed to investigate the relationship between expression level of multidrug resistance-associated protein (MRP) or P-glycoprotein (P-gp) genes and chemotherapy efficacy or clinical drug resistance in the patients with malignant lymphomas. Methods： Using the methods of semi quantitative reverse transcription polymerase chain reaction (RT-PCR) and flow cytometry (FCM), The authors examined the expression level of MRP and P-gp of 46 lymphoma patients. Results： The expression level and positive rate of P-gp in the recurrent patients was higher than that in untreated patients (P<0.001). There was no difference in MRP gene expression level and positive rate between recurrent and untreated patients (P>0.05). Chemotherapeutic effective rate in P-gp positive patients (26.67％ ) was lower than that in P-gp negative patients (83.87％ )(P<0.001). While there was no difference between MRP gene positive and negative patients, their chemotherapy effective rate had no difference. Relevant analysis showed that there was no correlation between MRP and P-gp (r-0.0808, P>0.05). Conclusion： P-gp expression correlates to multidrug resistance, and is the major mechanism of clinical drug resistance of lymphomas, whereas, MRP gene does not appears to play any role in that course.

Objective To discuss the coping modes for patients with chronic heart failure (CHF)dealing with their anxiety and depression; and to explore the possible way to guide effective nursing intervention aimed to reduce the patients' hospitalization rate and the length of hospitalization and to improve the quality of life for patients. Methods 120 patients with CHF were investigated by self-rating anxiety scale (SAS), selfrating depression scale and medical coping modes questionnaire (MCMQ). Results The score of patients with CHF in SAS was higher than norm model [(19.48 ± 3.81) vs (29.78 ± 10.07), t = 11. 127, P ＜ 0. 01] and the SDS was also higher than normal model (P ＜ 0. 01). The "facing" score of patients with CHF in MCMQ was statistically lower than that of normal model in China[(16. 08 ± 3.88) vs (19.48 ± 3.81), t = 2. 046, P ＜0. 05]; Both of the scores on "avoidance" and "surrender" were statistically higher than those of normal model (P ＜ 0. 05 or P ＜ 0. 01). Conclusions Most patients with CHF had the problems involving anxiety, depression and ineffective coping mode; patients' quality of life could be improved when their negative emotion released and their coping mode improved.
