Uncooked cornstarch--efficacy in type I glycogenosis

Uncooked cornstarch (UCCS) loads in 14 patients with type 1 glycogenosis revealed that satisfactory glycaemia was achieved for a median of 4.25 hours (range 2.5 to 6). Length of glycaemia was related weakly to UCCS dose, but not to patient age or measures of metabolic control. Careful monitoring is required during UCCS treatment.     

Temporomandibular joint arthrography: comparison of morbidity with ionic and low osmolality contrast media

We compared patient morbidity associated with temporomandibular joint (TMJ) arthrography using both meglumine/sodium diatrizoate (60%) and the new monoacidic dimer, Hexabrix, in a double-blind randomized clinical trial in 31 patients. Patients experienced maximal discomfort from TMJ arthrography with the initial joint filling and joint distension; this rapidly resolved over 10 minutes. Delayed exacerbation of pain is less than described for shoulder arthrography. The newer contrast media promise to decrease patient morbidity with arthrography.     

锌缺乏对神经病理性疼痛模型小鼠行为学的影响

目的研究饮食锌缺乏对神经病理性疼痛模型小鼠痛域的影响。方法制备饮食锌缺乏小鼠,采用小鼠坐骨神经分支选择损伤模型,金属自显影和原子吸收光谱检测小鼠脊髓后角锌稳态,检测小鼠痛域。结果 AMG结果证实,与假手术组相比,模型组小鼠和锌缺乏组小鼠脊髓后角游离锌离子减少,与模型组小鼠相比,锌缺乏小鼠脊髓后角游离锌离子减少。原子吸收光谱结果表明,锌缺乏组小鼠总锌含量较假手术组减少。痛域检测结果表明,锌缺乏小鼠痛域下降。结论锌离子可能参与小鼠脊髓后角痛觉专递。     

姜黄素对癫痫小鼠海马脑损伤的保护作用

目的研究姜黄素对匹罗卡品诱导的癫痫小鼠海马新生神经元和细胞凋亡的影响。方法姜黄素预处理后,小鼠腹腔注射匹罗卡品建立小鼠癫痫模型,应用新生神经元标记物双皮层蛋白(doublecortin,DCX)免疫组织化学染色及TUNEL染色对造模后72h的模型小鼠海马进行检测。结果 DCX免疫组织化学染色结果表明,与对照组相比,模型组及姜黄素处理模型组小鼠海马齿状回DCX阳性细胞明显减少;与模型组相比,姜黄素处理模型组小鼠海马齿状回DCX阳性细胞明显增多。TUNEL染色结果表明,与对照组相比,模型组及姜黄素处理模型组小鼠海马齿状回TUNEL阳性细胞明显增多;与模型组相比,姜黄素处理模型组小鼠海马齿状回TUNEL阳性细胞明显减少。结论姜黄素可能对匹罗卡品诱导的癫痫小鼠海马神经元有保护作用。     

巨大下颌骨囊性病变分期治疗效果评价

目的:探讨对巨大下颌骨囊性病变进行分期治疗的效果。方法:选择2005—2009年在本院收治的下颌骨范围大于5cm的囊性病变18例,其中伴牙列不齐者6例,一期局麻下行减压术,待范围减小至小于原来的1/2后,行二期全麻下囊性病变摘除术,即刻Bio-oss骨粉植入,术后每月定期拍摄口腔全景片观察骨密度变化,伴牙列不齐的6例患者手术后2个月开始以常规正畸加力牵引。结果:一期术后4~6个月,病变减小至原来的1/2左右,二期术后6~12个月,骨粉与周围正常骨密度基本一致,2~3a后无一例复发。6例牙列不齐的患者,经1~2a正畸治疗后,错畸形得以矫正。结论:分期治疗既彻底摘除了病变,又保存了下颌骨的连续性及自体牙,还可同时结合正畸治疗,改善错畸形,提高美学效果。     

小鼠角膜移植排斥反应中植片浸润细胞类型及引流淋巴结细胞表型的变化

目的：探讨小鼠角膜移植排斥反应中植片浸润细胞类型及引流淋巴结细胞表型的变化。 方法：建立小鼠角膜移植模型,术后不同时间点进行临床观察及角膜免疫荧光组织化学染色。采用三色流式细胞术分析移植术后3d颌下淋巴结（SMLN）、颈浅淋巴结（SCLN）的细胞表型变化。 结果：角膜移植术后6h,中性粒细胞、树突状细胞、巨噬细胞开始聚集并逐渐浸润植片;24hCD4^＋T和CD8^＋T细胞出现并侵入植片,2wk时达到高峰;术后12～21d所有植片均被排斥。移植后3dSMLN内CD4^＋T细胞比例较正常时明显下降（P=0.038）,而SCLN各细胞比例无明显变化。 结论：角膜移植术后植片迅速出现髓系及淋巴细胞浸润,伴有引流的SM LN内早期CD4^＋T细胞比例下降,二者间有一定关联。     

前列腺癌患者调强放疗计划中不同算法计算结果分析

目的 分析前列腺癌患者调强放疗计划设计时PBC和AAA算法计算得到的剂量学参数差异。方法 对13例术后接受调强放射治疗的前列腺癌患者进行调强放疗计划设计时,分别用Eclipse Version 8.10治疗计划系统提供的PBC和AAA算法进行剂量计算并用二维电离室矩阵进行验证测量,比较两种算法获得的HI、CI、PTV_DP、PTV_mean、直肠和膀胱V₅₀等参数差异,并将二维电离室矩阵测量的剂量分布与两种算法的计算结果分别进行比较获得γ通过率、单次照射时的及DD_mean等参数差异。结果 两种算法得到的靶区HI、CI、PTV_DP、PTV_mean平均相差分别为0.003、0.004、2.2%、10 cGy,直肠和膀胱V₅₀值平均差异分别为0.3%和1.3%。γ通过率、DD_max及DD_mean平均差异分别为0.9%、1.2%(2.4 cGy)和0.85%(1.7 cGy)。两种算法所获得的剂量学参数差异不大。结论 对前列腺癌患者进行调强放疗计划设计时,PBC和AAA两种算法均可使用。

??OBJECTIVE To evaluate retrospectively the clinical application of apatinib in a hospital. METHODS The medical records including apatinib were collected during April 2015 to March 2016. Then, the rationality and safety of drug use were evaluated. RESULTS The 84 patients used apatinib during this time, while 15.48% (15 patients) conformed to the approved indications. The major adverse reactions were gastrointestinal disorders, hypertension, skin disorders and myelosuppression. CONCLUSION Irrational use of apatinib such as off-label use, inadequate usage and dosage exists in clinic. Clinicians should pay close attention to the rationality of apatinib, and clinical pharmacists can improve the safety and effectiveness of therapeutic drugs by taking this as the breakthrough point.
