IMRT联合TP方案治疗晚期食管鳞癌的临床疗效及对患者血清MMP2、TIMP2、nm23-H1及不良反应的影响

目的分析调强放射治疗(IMRT)联合TP方案治疗晚期食管鳞癌的临床疗效及对患者血清基质金属蛋白酶2(MMP2)、组织金属蛋白酶抑制剂2(TIMP2)、nm23-H1及不良反应的影响。方法选取晚期食管鳞癌患者80例为研究对象,按随机数字表法将其分为观察组(n=40,采用IMRT联合TP方案化疗)、对照组(n=40,单纯采用IMRT治疗),比较2组临床疗效、治疗前后血清MMP2、TIMP2、nm23-H1表达阳性率、局控率与生存情况及不良反应。结果观察组治疗有效率(85.00%)明显高于对照组(65.00%)(P<0.05)。治疗后2组血清MMP2表达阳性率下降,而TIMP2、nm23-H1表达阳性率上升,且观察组治疗后血清MMP2表达阳性率低于对照组,而TIMP2、nm23-H1表达阳性率高于对照组(P<0.05)。观察组治疗后1年、2年局控率高于对照组,但2组治疗后1年、2年生存率差异无统计学意义(P>0.05)。观察组白细胞减少、放射性食管炎发生率高于对照组(P<0.05),2组其他不良反应发生率差异无统计学意义(P>0.05)。结论晚期食管癌患者采用IMRT联合TP方案治疗可获得较好的疗效,对患者血清MMP2、TIMP2、nm23-H1有明显改善,但可能会较单纯IMRT治疗具有更多不良反应,需加以监测。     

GRIA1、GRM3、TCF4基因单核苷酸多态性与精神分裂症的关联研究

目的 探讨GRIA1、GRM3和TCF4基因单核苷酸多态性与精神分裂症的关联,为精神分裂症的遗传学研究提供参考。 方法 选取昆明医科大学第一附属医院精神科的663例符合《精神障碍诊断与统计手册（第4版）》（DSM-IV）诊断标准的精神分裂症患者为病例组,以昆明市第一人民医院体检中心的690例健康人为对照组,使用SNaPshot基因分型方法对受试者GRIA1、GRM3、TCF4三个候选基因12个SNPs进行基因分型,并进行遗传学分析。 结果 GRM3多态性位点rs6465084的A等位基因频率与对照组相比差异有统计学意义（P=0.027）;以性别特异性做相关分析,表明多态性位点rs6465084 A等位基因频率在男性精神分裂症患者与正常对照组中差异有统计学意义（P=0.02）。 结论 GRM3多态性位点rs6465084可能与精神分裂症存在关联,其等位基因A可能增加精神分裂症的发病风险。     

CyclOBEAP (cyclophosphamide, vincristine, bleomycin, etoposide, doxorubicin, prednisolone) regimen with granulocyte colony-stimulating factor (G-CSF) for patients with aggressive non-Hodgkin's lymphoma: a pilot study. The Adult Lymphoma Treatment Study Group (ALTSG)

We conducted a multi-institutional collaborative study to examine the usefulness and safety of third-generation chemotherapy CyclOBEAP (cyclophosphamide, vincristine, bleomycin, etoposide, doxorubicin, prednisolone) combined with granulocyte colony-stimulating factor (G-CSF) in the treatment of aggressive non-Hodgkin's lymphoma (NHL). Subjects included patients with aggressive NHL who were 60 yr of age or younger and had been diagnosed as having a low-intermediate, high-intermediate, or high risk using the International Prognostic Index (IPI). A total of 24 patients were enrolled in the study between May 1997 and March 1998, including 9 low-intermediate-risk cases, 13 high-intermediate-risk cases and 2 high-risk cases. Although all 24 patients were originally enrolled in the study, one adult T-cell leukemia/lymphoma case was subsequently excluded. Thus, in the end, 23 cases were evaluated. Evaluation of the efficacy of therapy revealed complete remission in 20 patients (87%). Of these 20 patients, 8 were low-intermediate-risk cases (89%) and 12 were either high-intermediate- or high-risk cases (86%). Partial remission was achieved in 2 patients (8.7%). The 2-yr survival rate was 91.3%, and the 2-yr disease-free survival rate was 81.8%. Grade 3 or higher adverse reactions were granulocytopenia (87%), thrombocytopenia (17.4%) and liver dysfunction (4.3%). CyclOBEAP therapy has been associated with a high remission rate for aggressive NHL. When combined with G-CSF, a high relative dose intensity was maintained for each drug administered (0.94-0.97). Furthermore, although the observation period was short, both the survival rate and disease-free survival rate were good. Hence, we concluded that there were no problems associated with the procedure in terms of safety.     

TP方案治疗NP方案化疗失败的非小细胞肺癌的疗效观察

目的评价NP方案化疗后进展的晚期非小细胞肺癌（NSCLC）应用TP方案化疗的疗效和毒副反应。方法34例NSCLC均曾接受过NP方案化疗2周期,出现病情进展后接受TP方案化疗,紫杉醇135mg／m^2,d1,顺铂20mg／m^2,d1-4,21d为1周期,完成2周期评价疗效,观察毒副反应。结果34例中CR0例,PR3例（8．82％）,SD6例（17．65％）,PD25例（73．53％）,总有效率为8．82％。主要毒副反应是骨髓抑制和胃肠道反应。结论TP方案对NP方案化疗失败的晚期NSCLC有一定疗效,但有效率较低,提示有交叉耐药性。     

Malondialdehyde regulates glucose-stimulated insulin secretion in murine islets via TCF7L2-dependent Wnt signaling pathway

Evidence showed strong relations between malondialdehyde (MDA) levels and different pathological stages of diabetes. Here, an explicit system with freshly isolated islets and precisely controlled MDA gradient was employed to investigate the physiological effect of MDA on GSIS. Promoter analysis, pathway mapping, Q-PCR profiling, and siRNA verification were performed to clarify the intracellular signaling pathways. MDA at a moderately high level (5 and 10 μM) promoted GSIS and accompanied with ATP/ADP ratio, cytosolic Ca²⁺ level, and key regulators (GK, GLUT2, PDX1, and UCP2) changes in islets. Both upstream (PI3K and p-AKT) and downstream (TCF7L2 and TCF7) factors of Wnt pathway showed greatest changes. Knockdown of TCF7L2 blocked the MDA-induced GSIS elevation. These results indicated that MDA acted as a signaling messenger and regulated islet GSIS mainly through Wnt pathway. Therefore, the elevated MDA level and up-regulated Wnt signaling pathway could be an etiological factor in the development of hyperinsulinemia and type 2 diabetes.     

重组人血管内皮抑素联合TP方案治疗晚期非小细胞肺癌的临床疗效观察

目的观察重组人血管内皮抑素联合TP方案治疗晚期非小细胞肺癌的临床效果。方法将65例晚期非小细胞肺癌随机分为2组。治疗组给予重组人血管内皮抑素+TP方案治疗,对照组仅给予常规TP方案化疗。2个周期后评价疗效,并统计分析不良反应。结果治疗组有效率为54.5%,临床获益率为78.8%;对照组有效率为34.3%,临床获益率为62.5%。2组比较差异有统计学意义(P<0.05)。胃肠道反应、骨髓抑制及肝肾功能异常是最为常见的不良反应。2组不良反应比较差异无统计学差异(P>0.05)。结论重组人血管内皮抑素联合TP方案治疗晚期非小细胞肺癌疗效与单纯TP方案比较可使患者临床获益。
