Objective To detect Snail and Raf kinase inhibitor protein (RKIP) expressions in NSCLC (Non-Small Cell Lung Cancer) and their relationship with the pathological characteristics of tumor. Methods Immunohistochemistry was used to detect Snail and RKIP expression in 124 NSCLC samples and 67 paraneoplastic normal lung tissue samples. Snail and RKIP positive expression rates were compared upon clinicopathologic characteristics. Correlation of Snail expres-sion with RKIP expression was also analyzed. Results Positive expression rate of Snail was 79.03%in lung cancer, which is higher than that in normal lung tissue 19.40%(χ2=63.538, P<0.01);positive expression rate of RKIP was 36.29%in lung cancer which is lower than that in normal lung tissue 77.61%(χ2=29.716,P<0.01), Snail and RKIP expressions are corre-lated with tumor differentiation, TNM stage, lymph node metastasis and postoperative survival time ( P<0.05, respectively) . Snail protein expression is negatively correlated with RKIP expression in NSCLC (P<0.05). Conclusion High Snail ex-pression and the low RKIP expression might be important biological markers for invasion and metastasis of NSCLC, which might be used as important prognostic indicators in NSCLC.

Objective To observe the therapeutic effect of glycosaminoglycans(GAGs)on diabetes mellitus with early nephropathy in order to find a new therapeutic approach to diabetic nephropathy. Methods 60 cases of type 2 diabetic nephropathy(albuminuria:30 to 300mg/24h,male/female:38/22,ages:43-70 years old, course of disease:1-30 years)without hypertension were selected. Some indexes were analyzed before and after administration of regular therapy in routine group or glycosaminoglycans group. The elderly group and non elderly group of diabetes nephropathy were compared. When the metabolism is stable, the levels of endothelin (ET), Netricoxide (NO)and urinary albumin excretion rate(UAER)were measured. Results After three months treatment, the levels of UAER were decreased significantly in both GAGs group and routine group(P<0.01).After three months, UAER was decreased step by step, and there was no difference between the two groups. The levels of UAER had no change in regular group and there was significant difference between this group and the other two groups. In GAGs group, the levels of whole blood viscosity of medium shear rate 1,whole blood viscosity of medium sheer rate 2,whole blood viscosity of low shear rate were declined and serum NO increased significantly; that of plasma viscosity, whole blood reduced viscosity, ET were all decreased to some degree. Conclusion GAGs has the therapeutic effect on type 2 diabetic nephropathy patients with microalbuminuria because of decreasing UAER and reversing the development of DN. The benefit was positively correlated with the time of taking glycosaminoglycans.

Objective:To bring to doctors' attention to the first time attack of epilepsy in the patients with Parkinson' s disease, enhance the rational drug use and reduce the occurrence of adverse reactions in clinics. Methods: A Parkinson patient with the first time attack of epilepsy was synthetically analyzed on the mechanism of disease, therapy regimen and pharmaceutical care. Results:It was difficult to distinguish the symptom of epilepsy during the treatment of Parkinson' s disease from that of L-dopa induced dyskinesia, therefore, the suitable treatment was difficult to perform. Moreover, antiepileptic drug valproic acid could aggravate Parkinson syn-drome imperceptibly, which was easy to be ignored in clinics. Conclusion:L-dopa induced dyskinesia should try to avoid during the treatment of Parkinson, and should distinguish from the first time attack of epilepsy in order to choose proper antiepileptic drugs.
