Objective To investigate the expressions of Wnt-1 and FZD-1 in small cell lung cancer(SCLC) patients and their relations with chemotherapy resistance,clinical feature and prognosis.Methods Peripheral blood specimens were collected from 41 SCLC patients.The expression of Wnt-1 and FZD-1 in peripheral blood monouclear cells (PBMC) were detected.The relationship among the expression of Wnt-1 and FZD-1,clinicopathologic feature and prognosis was analyzed.Results The relative expression of Wnt-1 and FZD-1 in chemotherapy resistant group was significantly higher than that in chemotherapy sensitive group (all P ＜ 0.05).The expression of Wnt-1was positively correlated with that of FZD-1 (r =0.186,P ＜ 0.05).The FZD-1expression level was not correlated with patients' age,sex and smoking history (all P ＞ 0.05),but closely with clinic-staging (P =0.008).The Wnt-1 expression level was not correlated with patients' clinical features (all P ＞ 0.05).There was statistical difference in median survival time between Wnt-1 and FZD-1 high-expression group and low-expression group.Conclusions Wnt-1 and FZD-1relationships with chemotherapy resistance and prognosis.Wnt-1 and FZD-1 may act as an important role in chemotherapy resistance of SCLC and could be served as indicators for the chemotherapy resistance and outcome assessment of SCLC.

Objective To observe the effects of Fuzheng Huayu Capsule on the expressions of the main roles, Rock1 and Rock2, in RhoA/Rock signal transduction pathway in rats with myocardial infarction (MI);To explore the possible mechanism of Fuzheng Huayu Capsule to improve ventricular remodeling in myocardial fibrosis. Methods The MI model was induced by ligation of the left coronary artery. Rats with MI were randomly divided into the model group, Fuzheng Huayu group and Fasudil hydrochloride group. A sham-operation group threading without ligation was setting as a control group, with eight rats in each group. The rats were treated with corresponding medicine for 4 weeks from the second day after modeling. The expression of Rock1, Rock2 and its mRNA were detected by immunohistochemical and real-time PCR method. Results The protein expression of Rock1 and Rock2 in model group were significantly higher than those in the sham-operation group (P<0.05). The protein expression of Rock1 and Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group were lower than those in the model group. The mRNA expression of Rock2 was significantly higher in the model group than that in the sham-operation group (P<0.05). The mRNA expression of Rock1 in the Fasudil hydrochloride group was lower than that in the model group (P<0.05). The mRNA expression of Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group was lower than that in the model group (P<0.05). Conclusion Fuzheng Huayu Capsule can decrease the expression of Rock1, Rock2 and Rock2 in the marginal zone of myocardial infarction in rats with MI. The anti ventricular remodeling mechanism of Fuzheng Huayu Capsule maybe related with this.

OBJECTIVE: The aim of this study was to investigate ziprasidone plasma concentration, daily dose and clinical efficacy and safety in Han Chinese and Mongolian patients with first-episode schizophrenia. METHODS: A total of 123 inpatients affected by schizophrenia were recruited from the Mental Health Center of Inner Mongolia in China. Ziprasidone plasma concentration, clinical efficacy and side effects were systematically evaluated at baseline, and at 1, 2, 4, and 6 weeks. Metabolic measures such as changes in weight, body mass index (BMI), fasting blood glucose (FBG), triglycerides, and cholesterol, were also recorded. RESULTS: 90 patients completed the study. Compared with Han patients, on average, Mongolian patients received a significantly higher ziprasidone dosage for adequate symptom control during the 6-week period and had a lower plasma concentration-to-dose ratio. The Mongolian patients also experienced greater increases in weight and BMI. No significant differences between the two ethnic groups were found in the rate of reduction in the Positive and Negative Syndrome Scale (PANSS) score, Treatment Emergent Symptom Scale (TESS) total score, FBG, triglycerides, cholesterol or Q-Tc interval. CONCLUSION: Compared to Han Chinese patients, Mongolian patients appeared to have increased ziprasidone clearance and require higher doses to achieve effective treatment for schizophrenia.
