用３％海藻酸钠及２．２％ＣａＣｌ＿２所制备的微囊在高流速及高浓度的蔗糖溶液冲击下未见破裂，且微囊包裹活细胞经过二小时的剧烈搅拌，亦无损漏。改进法所制备的微囊具有良好的机械强度，其物理性能已达到临床进行包膜胰岛移植治疗糖尿病的要求。     

医院联合体的构建及成效研究

介绍了浙江省温州医学院附属第一医院和温州市第八医院构建联合体的过程,阐明在卫生改革不断深入的形势下,医院联合体的组建既符合卫生改革的总体精神,也提高了医疗卫生资源的利用率,是我国卫生改革的一种走向,也是拆"围墙"打破各种隶属、所有制,优化卫生资源的必然趋势.它的最终目的是有利于盘活存量,资源共享,提高效益,有利于为人民提供优质医疗卫生服务[1],同时也为浙江省<深化医药卫生体制改革若干意见>的稳步实施提供了生动的案例,为行政主管部门的决策提供了借鉴.     

JNK通路可能介导MPTP诱导的黑质神经元凋亡

目的 探讨氧化应激激活的c-jun NH2-terminal kinase(JNK)细胞凋亡通路在1-甲基-4-苯基-1，2，3，6-四氢吡啶(MPTP)诱导帕金森病(PD)小鼠黑质神经元凋亡中的可能作用。方法 采用MPTP制备PD小鼠模型，应用生化技术检测黑质区域谷胱甘肽(GSH)浓度及超氧化物歧化酶(SOD)活力，尼氏体染色和酪氨酸羟化酶(TH)免疫组织化学染色观察黑质神经元的损害情况，原位缺口末端标记(TUNEL)染色和活化型Caspase 3免疫组织化学染色观察黑质神经元的凋亡情况，同时采用蛋白兔疫印迹法检测磷酸化JNK及磷酸化c-jun蛋白表达水平。结果 MPTP诱导的PD小鼠黑质区域GSH浓度明显降低，SOD活力明显升高，黑质致密带尼氏体阳性神经元和TH阳性神经元显著脱失，磷酸化JNK及磷酸化c-jun蛋白表达水平上升，同时活化型Caspase 3表达阳性细胞增多，黑质神经元TUNEL染色的阳性率增高。结论 MPTP可诱导小鼠黑质神经元凋亡，机制与增强氧化应激并激活JNK细胞凋亡通路有关。     

手术及综合康复治疗膝关节僵直

目的 探讨膝关节纤维性僵直手术及围手术期、术后综合康复治疗的方法和意义.方法 26例膝关节纤维性僵直患者,采用髌骨外上方小切口,辅助关节镜下行关节内粘连松解,并结合徒手推拿松解.术前进行心理宣教,术后第2天开始经止痛泵维持在CPM机上行慢速全范围关节活动度功能锻炼,并行主被动伸屈膝功能锻炼、髌骨内推训练.结果 术后平均随访19个月(8～32个月),膝关节活动度从术前平均32°增至113°,平均提高81°.无皮肤坏死、创口裂开、肌腱断裂、骨折等并发症发生.结论 关节镜辅助下小切口松解治疗膝关节纤维性僵直的手术操作简单,创伤小,康复快.膝关节僵直围手术期及术后综合康复治疗,对膝关节功能恢复有重要意义.     

Prospective Open-Label Study of Botulinum Toxin Type A in Patients with Axillary Hyperhidrosis: Effects on Functional Impairment and Quality of Life

BACKGROUND: Patients with primary axillary hyperhidrosis experience substantial functional impairment and reduced health-related quality of life (HRQOL). Few studies have comprehensively evaluated the effects of botulinum toxin type A (BoNT-A) on these symptoms. OBJECTIVE: To prospectively assess the effects of BoNT-A on functional impairment associated with primary axillary hyperhidrosis. METHODS: Patients treated with BoNT-A 50 U per axilla at baseline were assessed 4 and 12 weeks later. Outcome measures included functional impairment as assessed by the Hyperhidrosis Disease Severity Scale and the Hyperhidrosis Impact Questionnaire and dermatology-specific HRQOL as assessed by the Dermatology Life Quality Index. RESULTS: At weeks 4 and 12 after BoNT-A treatment, 85% and 90% of patients achieved the a priori definition of treatment responder. Patients reported less occupational and emotional impairment, spent less time managing their hyperhidrosis, and had fewer difficulties in social situations. Adverse events were uncommon (5.5%), were mild, and did not require treatment. At study end, 53% of patients reported no dermatology-specific HRQOL impairment and 90% were satisfied with treatment. CONCLUSIONS: Significant, meaningful, rapid, and durable reductions in disease severity and functional impairment, as well as improvements in HRQOL, were seen following BoNT-A treatment. BoNT-A was safe and well tolerated, producing high levels of patient satisfaction.

Partial Least Squares Analysis and Mixture Design for the Study of the Influence of Composition Variables on Lipidic Nanoparticle Characteristics

Lipidic nanoparticles (NP), formulated from a phase inversion temperature process, have been studied with chemometric techniques to emphasize the influence of the four major components (Solutol®, Labrasol®, Labrafac®, water) on their average diameter and their distribution in size. Typically, these NP present a monodisperse size lower than 200 nm, as determined by dynamic light scattering measurements. From the application of the partial least squares (PLS) regression technique to the experimental data collected during definition of the feasibility zone, it was established that NP present a core-shell structure where Labrasol® is well encapsulated and contributes to the structuring of the NP. Even if this solubility enhancer is regarded as a pure surfactant in the literature, it appears that the oil moieties of this macrogolglyceride mixture significantly influence its properties. Furthermore, results have shown that PLS technique can be also used for predictions of sizes for given relative proportions of components and it was established that from a mixture design, the quantitative mixture composition to use in order to reach a targeted size and a targeted polydispersity index (PDI) can be easily predicted. Hence, statistical models can be a useful tool to control and optimize the characteristics in size of NP. ©2010 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 99:4603–4615, 2010
