Purpose:The phase I study was conducted to evaluate the maximum tolerated dose (MTD) and toxicity of weekly administered docetaxel combined with cisplatin in patients with non-small cell lung cancer ( NSCLC ). The other objective was to measure the pharmacokinetic/dynamics (PK/PD).Methods:In the dose escalation study, 15 patients with unresectable and metastatic untreated NSCLC with performance status(0-1) were enrolled. Escalating doses of D 25 mg/m 2 (30 mg/m 2, 35 mg/m 2, 40 mg/m 2) on day 1, 8, 15 were given as a 30 min iv infusions and C 75 mg/m 2 30 min iv infusion after D on day 1 and the cycle was repeated every 4 weeks. Blood samples were drawn on day 1 and 15 in the first cycle to measure the PK. Dose limiting toxicity(DLT) was based on Cycle 1 and defined as any Grade 3 non-hematologic toxicity not declining to Grade 2 or less within 4 days or any Grade 4 toxicity. Results:Chemotherapy was repeated for at least two cyc1es every 28 days. All patients were assessable for toxicities. Although grade 3/4 neutropenia occurred, there were no significant modifications of chemotherapy schedule. One patient developed an infection (DLT). Non-hematological toxicities, including nausea/vomiting, a1opecia, fluid intension and asthenia were tolerable. Based on these data, the MTD has not yet reached up to dose level of docetaxel of 40mg/m 2 weekly given in combination with cisplatin 75mg/m 2 every 4 weeks at the fixed dose. The exposure to docetaxel after Ⅳ administration on day 1 in combination with cisplatin and on day 15 without cisplatin , increased proportional to the dose for the range 25 to 40 mg/m 2, as measured by Cmax and AUC. No statistically significant difference between clearance values was shown for the 4 dose levels. The pharmacokinetics of docetaxel was not influenced by the coadministration of cisplatin on day 1 as compared to day 15, as the CmaxN, AUCN and CL were not statistically significantly different on both days. Fourteen patients were eva1uab1e for response, five cases achieved partial response, and thus the overall response was 35.7%. 1, 2, and 3 year survivals were 73%, 27%, and 20%, respectively. Weekly administration of docetaxel at 35mg/m 2 (days 1, 8, l5) combined with cisplatin 75mg/m 2 (day 1) is recommended for phase Ⅱ studies. Conclusions:Using the weekly schedule, toxicity was mainly manifested by non-hematologic profile and was well tolerated. A phase Ⅱ study is currently ongoing with docetaxel 35mg/m 2 as the suggested dosage.

Purpose:To study the efficacy and safety of docetaxel administrated weekly plus cisplatin in the treatment for patients with advanced non-small-cell lung cancer (NSCLC). Methods:Thirty-six patients with stage ⅢB,stage Ⅳ not treated previously by chemotherapy,or recurrenct after operation NSCLC received intravenous infusions of docetaxel at 35mg/m 2 three consecutive weeks,followed by a week of rest;and intravenous infusions of cisplatin at 75 mg/m 2 every four weeks. Results:There were 12 partial responses for an objective response rate of 33 %. The median survival was 11.5 months (range 4-27 months),and the 1-year survival was 50%. Hematologic toxicities,which were mild,included grade Ⅲ/Ⅳ neutropenia in 22%. The common nonhematologic toxicities included grade 2-3 nausea and vomiting (39%) and grade 2-3 asthenia (36%). Conclusions:Consecutive weekly administrations of docetaxel for 3 weeks plus cisplatin produce minimal myelosuppression and shows activity in the treatment of patients without previous chemtherapy with advanced NSCLC.

Methods Sixty healthy offsprings with or without a family history of essential hypertension were recruited and divided into two groups: (1) 30 from family with either one parent of essential hypertension; (2) 30 from family with both parents of essential hypertension; (3) control group,30 subjects from family with parents negative history.The levels of plasma CGRP,Ang Ⅱ and ET were determined by radioimmunoassay. Results The plasma levels of CGRP,Ang Ⅱ in one parent group were(28.3?10.4 pg/mL),(52.5?11.1 pg/mL) and (37.7?14.7 pg/mL),(58.4?9.1 pg/mL) in both parents group,which were increased significantly as compared with those in the control group (CGRP 19.9?10.5 pg/mL,Ang Ⅱ 45.3?9.9 pg/mL,P

Objective To observe the protective effect of anthocyanin on irradiation induced bone marrow c-kit positive cell injury, and further explore its possible mechanism. Methods Mouse bone marrow c-kit positive cells were collected by cell sorting method. There were 2 groups: control group and anthocyanin group, which were sub-divided into three groups and received 0 Gy, 1 Gy and 4 Gy irradiation respectively. The control group was added 700μL cell suspension and an equal volume of serum-free hematopoietic stem/progenitor cell culture medium. The 2 × 10-5 mol/L anthocyanin was co-cultured with mouse bone marrow c-kit positive cells of anthocyanin group half an hour before irradiation exposure, then cells were cultured for 18 hours under the conventional culture conditions (37℃,5%CO2). Mouse c-kit positive cell viability was measured by bioluminescence, and which was reflected by relative light units (RLU). The ability of colony-forming units was reflected by CFU-GM. The reactive oxygen species (ROS) level and mean fluorescence intensity (MFI) ofγ-H2AX were detected by flow cytometry. Results Compared to un-irradiated control group, the cell viability and the number of CFU-GM were decreased significantly, while the ROS level and MFI ofγ-H2AX were increased in c-kit positive cells irradiated with 1 Gy and 4 Gy (P<0.05). Compared to 1 Gy and 4 Gy irradiation groups, c-kit positive cell viability and the number of CFU-GM were increased, the ROS level and MFI of γ-H2AX were decreased in anthocyanin group (P < 0.05). Conclusion Anthocyanin exhibits a promising protective effect on radiation-induced bone marrow c-kit positive cell injury, which may be related to the alleviating ROS and DNA damage in bone marrow cells.
