玻璃体切割联合内界膜剥除治疗糖尿病性黄斑水肿

评估玻璃体切割联合内界膜剥除对糖尿病性黄斑水肿（DME）的疗效。方法：回顾性病例对照研究。2014年6月至2017年1月间因糖尿病视网膜病变合并玻璃体积血或增殖病变于温州医科大学附属眼视光医院杭州院区行玻璃体切割手术治疗，且术前或术中经光学相干断层扫描（OCT）检查确诊合并DME的患者31例（33眼）纳入研究。16例（18眼）术中联合内界膜剥除作为剥膜组，15例（15眼）仅接受玻璃体切割手术治疗者作为对照组。所有手术均由同一医师主刀完成。术后1、3个月随访时复查OCT，对比观察黄斑中心厚度（CMT）和视力的术后变化情况。随访中CMT和最佳矫正视力（BCVA）比较采用重复测量方差分析，组间CMT和BCVA比较采用独立样本t检验。结果：手术前，手术后1、3个月2组间比较LogMAR视力总体差异有统计学意义（F=15.93，P<0.001）。术后 1个月时剥膜组BCVA高于对照组（t=2.55，P=0.02），但术后3个月时2组间差异无统计学意义（t=0.82， P=0.42）。手术前，手术后1、3个月CMT总体差异无统计学意义（F=2.85，P=0.065）。术后1、3个月时，剥膜组的CMT均低于对照组，2组间差异均有统计学意义（t=2.24，P=0.03；t=3.79，P=0.001）。术后1个月时，剥膜组有效（与术前比CMT减少20%以上）、无效（变化不超过20%）及恶化（增厚超过 20%）的例数分别为8、6、4例，术后3个月时则分别为11、5、2例，与对照组相比，术后1个月时组间差异无统计学意义（Z=-1.687，P=0.092），术后3个月时剥膜组DME改善有效比例明显高于对照组，组间差异有统计学意义（Z=-2.177，P=0.029）。结论：对于非牵拉性DME，内界膜剥除有助于术后早期DME消退。

2型糖尿病患者血清抵抗素浓度与血脂代谢水平的临床意义

目的了解2型糖尿病患者血清抵抗素浓度与空腹血糖、血脂的关系。方法选择52例2型糖尿病患者和40例健康中老年人,分别分为糖尿病组和非糖尿病组,用竞争性酶联免疫吸附法测定各组空腹血浆抵抗素水平,同时检测空腹血糖、血脂各项指标。结果糖尿病空腹血浆抵抗素水平显著高于对照组(p<0.05)。抵抗素与甘油三脂、空腹血糖呈正相关关系(r=0.687,p<0.05,r=0.849,p<0.05),而抵抗素与其余各项血脂指标、性别之间无明显相关性。结论血清抵抗素水平与2型糖尿病关系密切,抵抗素水平可能影响体内能量代谢和平衡,与糖、脂代谢的关系更为密切。

目的 评估单纯行玻璃体切除术对外因性细菌性眼内炎的疗效。方法 外因性细菌性眼内炎21例(21只眼)，其中白内障摘除联合人工晶状体植入术后1只眼，眼球穿通伤后20只眼。均作睫状体平部三切口玻璃体切除术，晶状体混浊者一并切除，若有球内异物一并取出，伴视网膜脱离者，重水或气／液交换复位视网膜后行眼内炎光凝、长效气体或硅油填充以及巩膜环扎，术中灌注液内不加入庆大霉素，术毕不作玻璃体腔注药，术后联合抗生索和激素静脉用药。结果 炎症控制20只眼，术后矫正视力提高20只眼，有效率为80．95％。结论 玻璃体切除术对严重细菌性眼内炎而言是最重要的治疗手段。     

国产唑来膦酸治疗肿瘤高钙血症多中心Ⅱ期临床观察

Objective： To evaluate the effect and safety of clinical use of zoledronic acid in the treatment of malignant hypercalcemia. Methods： A multi-center, open phase II clinical trial was conducted in 15 cases with malignant hypercalcemia who received zoledronic acid intravenously for 15 min. The level of blood calcium and side effects were recorded regularly within 28 days after injection. Results： One case was dropped out due to bad compliance. The complete response rate （the corrected serum calcium was reduced to normal level） was 100.00% （14/14）. The medium time of complete response rate was 5.07 days. The medium maintain time was 22.30 days. Slight, or moderate fever was observed. Conclusion： Zoledronic acid can effectively reduce the malignant hypercalcemia. The use of zoledronic acid appears to be safety and convenient.     

异常孕产史妇女风疹病毒感染的研究

目的了解孕妇风疹病毒的感染率；为早期预测异常妊娠的出现、及时防治提供理论依据。方法采用酶联免疫吸附法（ＥＬＩＳＡ）检测２０６例有异常孕产史妇女和８１０例正常孕妇血清中特异性抗风疹ＩｇＭ抗体。结果有异常孕产史的妇女风疹病毒感染率明显高于对照组（ｘ２＝１１．３３Ｐ＜０．０１）。结论风疹病毒感染是造成异常妊娠的主要原因之一；孕前或孕早期进行风疹病毒感染的检测，对降低异常妊娠的出现具有重要意义。

抗体阴性重症肌无力发病与凝集素之间关系研究

借助研究抗体阴性重症肌无力（ＭＧ）发病与凝集素之间的关系，以阐明其发病过程是否与凝集素有关。方法观察伴刀豆球蛋白Ａ（ＣｏｎＡ）和麦胚凝集素（Ｔｒｉｔｉｃｕｍ）及其凝集素－糖复合物对ＴＥ６７１细胞表达的乙酰胆碱受体（ＡＣｈＲ）功能的作用，以及对α－ＢｕＴｘ结合试验的影响。结果有两种凝集素对ＡＣｈＲ功能均有抑制作用，抑制率（％）分别为５４±１４（ｎ＝１１）和４７±１６（ｎ＝１０），此作用可被３种糖抑制，抑制率（％）分别为：９５±５（ｎ＝５）和８４±８（ｎ＝５）；６９±６（ｎ＝４）和６５±５（ｎ＝４）；３９±４（ｎ＝５）和５７±６（ｎ＝５）；ＣｏｎＡ抑制α－ＢｕＴｘ结合试验，而Ｔｒｉｔｉｃｕｍ则不能。结论Ｔｒｉｔｉｃｕｍ和抗体阴性ＭＧ患者非ＩｇＧ部分对ＡＣｈＲ功能和α－ＢｕＴｘ结合试验的作用类同或一致，表明抗体阴性ＭＧ患者非ＩｇＧ部分中的内源性Ｔｒｉｔｉｃｕｍ样糖蛋白在其发病过程中起重要作用。     

Role of macrophage and smooth muscle cell apoptosis in association with oxidized low-density lipoprotein in the atherosclerotic development.

To examine the role of the apoptosis of macrophages and smooth muscle cells in the development of atherosclerosis, human aortic tissues with intimal lesions were immunostained with antibodies against terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-biotin nick end labeling (TUNEL), single-stranded DNA (clone F7-26), and active caspase-3. Apoptotic cells were detected in the intima using both TUNEL and single-stranded DNA, however, the latter method was the more sensitive one for detecting apoptotic cells in the early stages of atherosclerosis. The number of apoptotic cells increased as the disease progressed. It implies that the apoptosis of intimal cells is involved in the formation of atherosclerotic lesions. In addition, quantitative analyses of the cell types undergoing apoptosis using double-immunostaining revealed that the susceptibility of macrophages and smooth muscle cells to apoptosis was greater specifically in atheroma than in the other atherosclerotic lesions, and macrophages were more susceptible to apoptosis than smooth muscle cells. The frequency and spatial distribution of oxidized low-density lipoprotein (oxLDL) (FOH1a/DLH3)-positive cells were examined by immunohistochemistry, and the results resembled those of apoptotic cells. The number of oxLDL-positive cells in the intima significantly correlated with the susceptibility of smooth muscle cells, but not with that of macrophages, to apoptosis. These results suggest that oxLDL affects the apoptosis of smooth muscle cells during the atherosclerotic development.
