Objective: To explore the expression and gene amplification status of human epidermal growth factor receptor-2 (HER2) in the different stages of invasive urothelial bladder carcinoma. Methods:Tumor tissues from 49 patients with different stages of invasive urothelial bladder carcinoma were tested by immunohistochemical staining for HER2 and HER2 gene fluorescence in situ hybridization. Results:The number of male patients was higher than that of females. The positive rate of HER2 protein expression was higher in the patients with the higher stage of invasive urothelial bladder carcinoma. However, no gene amplification was observed in all patients. Twelve patients had ployploid chromosome 17. More ployploids were observed in the patients with the higher stage of inva-sive urothelial bladder carcinoma. Conclusion:The increase in the protein expression of HER2 in the invasive urothelial bladder carci-noma patients was not caused by gene amplification. Other transcriptional and post-transcriptional mechanisms were probably involved in the regulation of the HER2 protein.

Objective To compare the curative effects and safety of mirtazapine and fluoxetine in treatment of elderly depressive patients with insomnia.Methods 92 cases of elderly depressive patients with insomnia were randomly divided into two groups: the mirtazapine treatment group and the fluoxetine treatment group. The period of treatment was six weeks. The antidepressant effect was assessed with the drop rate of Hamilton Depression Scale (HAMD),the effect of improving sleep was assessed with HAMD sleep disturbance factor and the Pittsburgh Sleep Index (PSQI), and the administration of security was assessed with vice Treatment Emergent Symptom Scale (TESS).Results After treatment, the effective rate of the mirtazapine group was 90.9% (40/44), that of the fluoxetine group was 84.1% (37/44). In the end of 1st, 2nd, and 4th weeks after treatment, the difference between the two groups were significant (P<0.001). At the end of 6th week, the difference was not significant (P>0.05) in HAMD; the difference was significant in HAMD sleep disturbance factor and PSQI score (P<0.05).Conclusion The clinical effects of mirtazapine in treatment of depression are similar to that of fluoxetine, but mirtazapine takes effects fast, can improve the symptoms of insomnia, has higher safety and better compliance, and is more appropriate for the depressive elderly patients with insomnia than fluoxetine.

ObjectiveTo investigate the quality of life (QOL) of the epilepsy patients and the factors affected the QOL.Methods200 cases were investigated using the Quality of Life in Epilepsy Inventory 10 (QOLEI-10) and the Washington Psychosocial Seizure Investigate (WPSI). 200 healthy persons were chosen as normal control group. ResultsThe QOL of the patient group were significantly poor as compared with that of normal control group(P<0.01). The factors that the patients always faced with were disability in the attack control, short in money, unemployment, restriction of movement, disability in intercommunication, psychological disorder (depress, strain, anxiety, dread, shame feel, cognitional dysfunction, etc.), as well as the difficult to get professional curtains, taking medicine improperly and side effects of the medicine. Conclusions The factors mentioned, which were usually neglected by many doctors, do affect the QOL of epilepsy patients, and hinder the epilepsy treatment effectively.

To investigate the effect and possible mechanism of echinacoside-containing serum on the osteogenic differentiation in rat bone marrow mesenchymal stem cells. Rat bone marrow mesenchymal stem cells were cultivated by the whole bone marrow adherence method. The 3rd generation of cells were divided into 3 groups: the blank control group, the classic osteogenic-induced group and the 10% echinacoside-containing serum group. The expression of alkaline phosphatase and osteocalcin were detected by ELISA. The ex- pression of ZHX, protein was detected by Western blot technique. RT-PCR technique was used to detect the expression of ZHX₃mRNA. According to the result, the expressions of the alkaline phosphatase and osteocalcin in the classic osteogenic-induced group and the 10% echinacoside-containing serum group were significantly higher than that of the blank control group (P <0. 01). And expressions of the alkaline phosphatase activity and osteocalcin in the 10% echinacoside-containing serum group were significantly higher than that in the classic osteogenic-induced group (P < 0.01). Meanwhile, the classic osteogenic-induced group and the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the black control group, with significant differences (P < 0.01); the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the classic osteogenic-induced group, with a significant difference (P < 0.01). In conclusion, 10% echinacoside-containing serum can promote the differentiation of the bone marrow mesenchymal stem cells cultured in vitro. Its mechanism may be correlated with the increase in the ZHX₃expression.
