MRI成像对子宫内膜癌侵犯肌层的评估

目的探讨MRI对子宫内膜癌肌层浸润深度的评估价值。方法回顾性分析67例经分段刮宫并施行手术治疗的子宫内膜癌患者MRI表现,并与术后病理结果进行对照。结果 MRI判断子宫内膜癌局限于内膜、浸润浅肌层、浸润深肌层及浸透浆膜层的准确性分别为92.5%、80.5%、88.0%、80.5%。结论磁共振可多方位、多序列、多角度成像,对软组织有较高分辨率,对准确判断子宫内膜癌肌层有无浸润具有明显优势。     

Prophylactic juxtapapillary laser photocoagulation in pediatric morning glory syndrome

AIM: To determine the anatomic and visual outcomes of prophylactic juxtapapillary laser photocoagulation treatment alone in the prevention of retinal detachment (RD) in a cohort of pediatric patients diagnosed with morning glory syndrome (MGS). METHODS: A total of 24 eyes of 22 consecutive patients aged 0-15y diagnosed with MGS treated with prophylactic juxtapapillary laser photocoagulation alone were reviewed. Data including demographics, ocular examination, anatomic and visual outcomes, following treatment and complications were collected. RESULTS: Two patients had bilateral laser treatment and 20 had monocular laser treatment. The age at treatment of 13 (59.1%) patients was less than 12mo. The presenting symptoms included strabismus (6/22, 27.3%), decreased vision (2/22, 9.1%), and routine fundus screening (14/22, 63.6%). Fifteen (68.2%) patients underwent cranial magnetic resonance imaging (MRI) examinations, and 3 of those 15 (20.0%) had abnormal findings in the nervous system. Based on preoperative wide-field fundus photography and B-scan echography, all (100.0%) eyes had no obvious RD. On postoperative 1mo and 6mo and the following follow-ups, the anatomic outcomes of all eyes remained stable. The mean follow-up duration was 27.7±17.5mo. No severe complications were found. Preoperative visual acuity acquired from 2 (9.1%) patients ranged from light perception to 20/200. Postoperative acuity acquired from 11 (50.0%) patients ranged from light perception to 20/125. CONCLUSION: The preliminary anatomic and visual outcomes of prophylactic juxtapapillary laser treatment alone in pediatric MGS patients are relatively stable in a short-term follow-up. Further long-term clinical observation will be needed to confirm its efficacy and safety.     

双相障碍的功能损害及相关因素

本文目的是探讨双相障碍社会功能和认知功能的特点及其影响因素,为临床识别与干预提供参考。研究显示,双相障碍功能损害显著,即使在稳定期,双相障碍患者仍存在不同程度的认知功能和社会功能损害,双相障碍的功能损害可能存在病理心理机制和相关影响因素。本文从双相障碍社会功能损害、认知功能损害和二者的关系等方面进行阐述,并总结当前研究的不足之处。

大剂量硝酸甘油介入~(99m)Tc-MIBI心肌SPECT判定存活心肌的研究

目的：探讨大剂量硝酸甘油介入（大剂量硝充法）99mTc-MIBI心肌SPECT对存活心肌判定的价值。材料和方法：对44例大剂量硝充组和31例小剂量硝充组的心肌梗塞患者均行静息和硝充法心肌显像。采用9节段评分法对两次显像进行了比较。其中两组中分别有18例和17例于冠脉血管再通术（PTCA或CABG）后半年内再次复查了静息心肌显像并与术前比较。结果：大剂量硝充组静息心肌显像灌注异常节段为154个，硝充后有77个节段呈现了再分布，总再分布率为50．0％（77／154）；小剂量硝充组静息心肌显像灌注异常节段为110个，硝充后有35个节段呈现了再分布，总再分布率为31．8％（35／110）。大剂量和小剂量组中18例和17例PTCA和CABG患者术后静息心肌显像与硝充法心肌显像比较阳性符合率分别为85．7％和68．8％．预测准确率为对71．9％和50．9％。结论：大剂量硝酸甘油介入99Tc-MIBI心肌SPECT具有较高的存活心肌检出率和预测准确性。     

CT导引下肝肾囊肿抽吸硬化治疗

目的：总结CT导引下肝肾囊肿穿刺抽吸硬化治疗的疗效和操作经验。材料和方法：肝囊肿11，肾囊肿15例，多囊肾1例，囊肿大小为3．5－12cm，均用15cm长20GGreene针穿刺治疗，抽出囊液量为21－550ml，囊液抽净后注入99．7％的无水酒精。结果：治疗后症状均有明显好转或消失，本组随访肝囊肿7例、肾囊肿11例，疗效指数I级1例（多囊肾），Ⅱ级肝肾囊肿各2例，Ⅲ级肝囊肿5例肾囊肿8例。穿刺操作顺利，无严重并发症发生。结论：CT导引下肝肾囊肿抽吸硬化治疗操作简便、创伤小、疗效高可作为替代外科手术的有效的治疗方法，多囊肾的单纯抽吸治疗可明显减轻症状，改善肾功能，是一种较好的治疗手段。
