InfluenceofQingdaiCompoundCapsule（复方青黛胶囊）ontheExpressionofc－mycinPsoriaticKeratinocytes

In this immunohistochemical study, the authors detected the expression of c-myc in ker-atinocytes ( ECK) from 30 psoriatics before and after Qingdai Compound Capsule ( QDCC) treatment and 12normal subjects for control. The results showed that the ECK of patients betore treatment was significantlyhigher than that in the normal control group, and its level was correlated with histopathological changes of af -fected skin. After treatment the ECK was normalized. It is believed that QDCC could decrease the ECK inpsoriatics and this effect was probably mediated by inhibiting c-myc expression. This study provided an ex-perimental evidence for the application of QDCC in treating psoriasis.

Effect of compound Guizhu capsule on phosphate and tension homology deleted on chromsome ten and murine double mimute 2 gene expression in lung cancer of mice

OBJECTIVE: To observe the inhibitory effect of the Chinese herbal compound Guizhu capsule(CGZC)on lung cancer and explore the possible mechanism underlying its actions by evaluating its effects on the expression of phosphate and tension homology deleted on chromsome ten(PTEN) and murine double mimute 2(MDM2) in lung cancer model mice.METHODS: A mouse model of transplanted lung cancer was established by subcutaneous inoculation of cancer cells into the axillae of mice. Twenty-four hours later, the mice were weighed and randomly divided into the model control group, cisplatin group(DDP group), and high, moderate and low dosage CGZC groups, with ten mice in each group. The control mice received an equal volume of distilled water. DDP was intraperitoneally injected at 1 mg/kg in the DDP group, once a day for 3days. CGZC diluted with distilled water was admin-istered at 20 g/kg(10 times the clinical adult dosage) in the high-dose group, 10 g/kg(5 times the clinical adult dosage) in the moderate-dose group and 5 g/kg(2.5 times the clinical adult dosage) in the low-dose group once a day for 10 days. On the11 th day, the mice were weighed and killed. The tumor tissues were weighed and the tumor inhibition rate was calculated. PTEN and MDM2 protein expression were detected by immunohistochemical analysis of tumor tissues.RESULTS: The CGZC high-and moderate-dose groups showed a significant inhibitory effect on tumor growth(P < 0.05); there was no significant difference between the high dose group and the DDP group(P > 0.05). The CGZC high-dose group also showed enhanced expression of PTEN protein(P <0.01) and decreased expression of MDM2 protein(P < 0.01) in lung cancer cells of the mice. There was no significant difference between the high dose group and the DDP group.CONCLUSION: CGZC has a significant inhibitory effect on transplanted lung cancer in mice. The mechanism may involve reducing expression of PTEN and decreasing the expression of MDM2 in the lung cancer tissues of the mice.
