METHODS: The eligibility criteria were: (1) histologi-cally proven measurable gastric cancer; (2) performance status of 0 or 1; (3) no prior chemotherapy or comple-tion of prior therapy at least 4 wk before enrollment; (4) adequate function of major organs; (5) no other active malignancy; and (6) written informed consent. The regi-men consisted of irinotecan (60 mg/m2) on d 1 and 15 by 24-h infusion and cisplatin (10 mg/m2) on d 1, 2, 3, 15, 16, and 17. Treatment was repeated every 4 wk. RESULTS: Thirty-one patients were registered between April 2000 and January 2001. The response rate for all 31 patients, 20 patients without prior chemotherapy, and 11 patients with prior chemotherapy was 52% (16/31), 60% (12/20), and 36% (4/11), respectively. The median survival time was 378 d. The median number of courses given to all patients was 2. Grade 4 neutropenia oc-curred in 11 (35%) patients, while grade 3 to 4 diarrhea or nausea occurred in 1 (3%) and 3 (10%) patients, respectively. Fatigue was minimal as grade 1 fatigue was found only in 3 (10%) patients. Other adverse events were mild and no treatment-related deaths occurred.CONCLUSION: This regimen showed a high level of ac-tivity and acceptable toxicity in patients with metastatic gastric cancer.展开更多

Methods ：Twenty cases （5.8-7. 5 years old ） with skeletal crossbite were treated by bonding the bite plate combined with the face mask protracting the upper jaw. Cephalometric radiographs were taken and analyzed before and after treatments. Results： On average, in all 20 cases the maxilla was moved by 2.06 mm forwards the mandible was turned 2.45° downward and backwards the skeletal crossbites were corrected and the facial profiles were improved satisfactorily. The period of treatment was conducted for 1.7 months on average. Conclusion： A good effect can be achieved by bonding bite plate combined with the face mask protracting the upper jaw to treat skeletal crossbite in the early mixed dentition, which will benefit the craniofacial growth and the development of young children.展开更多

However tumor progression is the role with median survival of almost 14 months. With lack of effective second line chemotherapy, many physicians and some guidelines advocate prolonged use of adjuvant TMZ more than 6 months. We conduct this study to test the efficacy of protracted adjuvant conventional dose TMZ over the standard 6 doses of adjuvant TMZ. Material and Methods: This phase II trial enrolled patients newly diagnosed as GBM, older than age 18 years, with a Karnofsky performance score (KPS) of ≥60, Neurological Performance Scale (NPS) of ≤3. Patients were randomly assigned to the standard concurrent chemoradiotherapy (CCRT) followed by 6 cycles of adjuvant TMZ or the same treatment with more than 6 cycles of adjuvant chemotherapy extended as long as the patient in good performance, with no unacceptable toxicity, no signs of disease progression. The primary end point was OS. Results: A total of 59 patients were recruited in the study and were randomized in two arms. 29 patients joined arm 1 aiming at receiving CCRT followed by adjuvant 6 cycles TMZ (6 cycles arm) and 30 joined arm 2 aiming at receiving the same treatment with more than 6 cycles of TMZ (>6 cycles). 16 patients managed to complete the adjuvant 6 cycles in arm 1. 19 patients in arm 2, completed the 6 cycles with additive more doses with a median of 11 cycles (range: 8 - 23 cycles). Median PFS was 12.1 months for (6 cycles) arm, and 18.8 months for (>6 cycles) arm, HR 0.88 (95% CI: 1.185 - 4.901) (P 0.015);the overall survival for (6 cycles) arm was 18.1 months, versus 24.1 months, HR 0.70 (95% CI: 1.007 - 4.037) (P 0.048). No significant added toxicity was notice and the 4 weekly TMZ was well tolerated. Conclusion: This study concluded that protracted adjuvant TMZ after concurrent chemoradiotherapy could be a feasible strategy for GBM. This strategy warrants a large phase III randomized trial.展开更多

Methods: One hundred patients of IPCP were divided equally into two groups, the TCM-WM group treated with Maqin Qizhu Decoction combining with antibiotics and the control group treated with antibiotics alone. Efficacy of the two groups was compared after 1 course（15）days） of treatment. Results: The total effective rate of the TCM-WM group was better than that of the control group. Moreover, the days needed in curing coughing, dyspnea, rales and X-ray shadow absorption of the former were fewer than those of the latter. Conclusion: The integrated TCM-WM therapy in treating IPCP could both inhibit the pathogens effectively and improve the humoral immunity and resistant ability of organism.展开更多
