简介：摘要目的复制Feeney's自由落体模型并对实验体会进行总结。方法对14只雄性SD大鼠进行麻醉、开颅，用自制打击装置打击大鼠的皮层，模型复制后进行实验观察。结果大鼠有2只因失血过多而死亡，7只无明显表现，5只肌张力下降，运动时拖行对侧肢体行走。结论Feeney's自由落体模型可实现局部脑区不同强度的打击，动物死亡率低，但该模型的复制过程中颅骨钻容易损伤皮层，动物易因出血过多而死亡。

简介：AbstractObjective:Scoping review of published literature to establish clinical characteristics and audiologic outcomes in patients diagnosed with Susac’s Syndrome(SS) who have undergone cochlear implantation (CI).Data sources:All published studies of CI in SS and contribution of two of our own patients who have not been reported previously.Methods:A comprehensive search of MEDLINE (via PubMed) was carried out in March 2020 using the following keywords and related entry terms: Susac’s Syndrome, Cochlear Implantation. Results: Our search identified a total of five case reports of CI in SS. With the addition of our two patients reported here, we analyzed characteristics and outcomes in seven patients. Mean age at implantation was 30 years old (range 19-46), with six women and one man implanted. Mean time from onset of hearing loss to implantation was 17 months (range three months to four years). Best reported postoperative speech understanding was reported via different metrics, with six of seven patients achieving open set speech scores of 90% or better, and one subject performing at 68%. Vestibular symptoms were present preoperatively in four of seven patients (57%), with vestibular testing reported in two patients, and showing vestibulopathy in one patient. No complications were reported following cochlear implantation.Conclusion:Cochlear implantation is a viable option for hearing rehabilitation in patients with SS, with levels of attainment of open set speech comparable to other populations of CI candidates.

简介：AbstractThe main treatments for Parkinson’s disease (PD) currently include surgery, rehabilitation, and most commonly, drug therapy. However, the drugs that are currently used to treat PD provide only symptomatic relief and delayed disease progression but have no curative effect and cause many adverse reactions. When considering pathogenic factors and metabolic regulation, PD and type 2 diabetes have a high rate of comorbidity; this provides a theoretical basis for the treatment of PD with first-line antidiabetic drugs. Among these agents, metformin reduces neuronal damage in the brains of PD patients via neuroprotection and the inhibition of oxidative stress and inflammatory responses, thus providing a novel strategy for the clinical treatment of PD. Here, we present the current state of knowledge about the use of metformin to treat PD and discuss its clinical prospects.

简介：Hirschsprung’s病(简称H病)是一种肠壁神经发育障碍的先天性畸形,其发生率甚高,仅次于直肠肛门畸形,占消化道先天畸形第二位。国内称谓“先天性巨结肠症”。然其命名以Hirschsprung’s病或肠道无神经节细胞症似较恰当。

简介：摘要目的探讨完全后腹腔镜经膀胱外途径规范化直视下(P.R.E.S.S.)膀胱袖套状切除术的操作要点和疗效。方法回顾性分析2017年8月至2020年12月收治的95例上尿路尿路上皮癌(UTUC)患者的病例资料，分别为海军军医大学长征医院30例，北京大学第一医院21例，烟台毓璜顶医院20例，大连医科大学附属第二医院21例，东部战区总医院3例。男57例，女38例。平均年龄(67.7±10.0)岁。中位肿瘤最大径3.0 cm。95例均行单次体位全程后腹腔镜肾输尿管全长切除联合P.R.E.S.S.技术膀胱袖套状切除术，根据术者手术习惯和经验分别采用四孔法(36例)和五孔法(59例)套管布局完成手术。四孔法组和五孔法组的年龄[(66.3±11.2)岁与(68.6±9.1)岁]、性别(男/女：25/11例与32/27例)、体质指数[(25.0±3.0)kg/m2与(24.8±3.4)kg/m2]、肿瘤最大径[2.8(1.6，3.5)cm与3.0(2.0，4.0)cm]、肿瘤侧别(左/右：19/17例与34/25例)、临床分期(T1～2/T3～4/Tis期：25/10/4例与49/10/0例)、多灶性肿瘤(3例与2例)比较差异均无统计学意义(P>0.05)；术侧合并肾积水(13例与39例，P＝0.004)、肿瘤位置(肾盂肾盏及上段输尿管/中段输尿管/下段输尿管：23/9/4例与35/4/20例，P＝0.005)的差异均有统计学意义。术中行P.R.E.S.S.技术膀胱袖套状切除时，以脐动脉索为解剖标志，扩大输尿管周围的盆底侧方腹膜外间隙，切开膀胱壁后形成气膀胱效应，进行充分的膀胱袖套状切除和确切的膀胱袖口关闭。记录围手术期临床指标及随访结果。比较四孔法组和五孔法组的相关临床指标，分析套管布局方式对手术操作的影响。结果本研究95例中，91例(95.8%)采用P.R.E.S.S.技术完成膀胱袖套状切除；1例(1.1%)因出血中转开放手术；3例(3.1%)因局部空间显露困难，仅以Hem-o-lok夹闭输尿管远端完成手术。手术时间中位值180(125，230)min。术中估计出血量中位值100(50，100)ml。总体并发症发生率10.5%(10/95)，其中术中并发症2例(2.1%)均为出血，1例术中输血400 ml，1例中转开放手术，未输血；术后并发症8例(8.4%)，其中Clavien-DindoⅡ级7例[继发出血3例，药物过敏、急性肾功能减退(血肌酐490 μmol/L)、肺部感染及淋巴漏各1例]，Ⅲa级1例(肠梗阻，局麻下置入肠梗阻导管)，患者经对症治疗后均顺利出院。四孔法组和五孔法组在手术中转率[8.3%(3/36)与1.7%(1/59)]、术中估计出血量(100 ml与60 ml)、术中淋巴结清扫率[25.0%(9/36)与20.3%(12/59)]、P.R.E.S.S.技术膀胱袖套状切除成功率[91.7%(33/36)与98.3%(58/59)]、并发症发生率[13.8%(5/36)与8.5%(5/59)]、肿瘤病理分期(pT1～2/pT3～4/pTis期：22/11/3例与37/19/3例)以及复发转移比例[8.3%(3/36)与3.4%(2/59)]方面差异均无统计学意义(P>0.05)；在手术时间(190 min与170 min，P＝0.011)和术后住院时间(5 d与6 d，P＝0.005)方面差异均有统计学意义。结论P．R.E.S.S.技术通过建立扩大的盆底侧方腹膜外间隙和气膀胱效应，以脐动脉索为解剖标志，可直视下确切地行膀胱袖套状切除术，用于单次体位完全后腹腔镜肾输尿管全长切除术安全、可行。五孔法布局较四孔法布局更适用于下段输尿管肿瘤患者，但可能延长术后住院时间。

简介：目的:探讨S100A8、S100A9在子宫颈鳞癌及正常宫颈组织中的表达及其意义。方法:采用半定量的RT-PCR技术和免疫组织化学的方法,从mRNA及蛋白水平检测32例子宫颈鳞癌和15例正常宫颈组织中S100A8、S100A9的表达,及与不同临床病理参数的关系。结果:子宫颈鳞癌组织中,S100A8、S100A9在mRNA及蛋白水平上均低表达(P<0.05),其中,低分化肿瘤的表达明显低于高、中分化肿瘤(P<0.05)。结论:S100A8、S100A9在子宫颈鳞癌组织中低表达,且可能与鳞状细胞的分化程度相关。提示S100A8、S100A9低表达可能与子宫颈鳞癌的发生发展有关系。

简介：［摘要］目的探讨Fahr’s病的CT表现和临床资料，以更好地认识Fahr’s病。方法回顾性分析9例临床确诊为Fahr’s病的临床和影像学资料，全部病例均行颅脑CT扫描。结果全部病例发病年龄为15～70岁，血清钙、磷均在正常范围，CT表现为颅内广泛对称性钙化，主要累及基底节、小脑齿状核、皮质下和丘脑。临床表现最常见有帕金森综合征，其次有精神障碍、记忆力下降、智力低下、癫痫、舞蹈症等。结论根据CT表现、临床表现、实验室检查和家族病史，可以对Fahr’s病作出正确的诊断，CT是Fahr’s病诊断最有价值的影像学检查，预防与对症治疗是目前主要治疗目的。

简介：摘要目的探讨乳头Paget’s病的临床特点、诊断及治疗方法，提高对乳头Paget’s病的诊治水平。方法回顾性分析我院2011年8月至2014年8月间收治的12例乳头Paget’s病患者的临床资料结果单纯湿疹样改变者2例，单纯乳腺肿块者3例，乳头湿疹样改变伴乳腺肿块者7例。最终病理证实乳腺浸润性导管癌伴乳头Paget’s病者8例，占所有病例的66.7%；导管内癌伴乳头Paget’s病者3例，占所有病例的25%；导管内癌局部微浸润伴乳头Paget’s病者1例，占所有病例的8.3%。结论乳头paget’s多伴有乳腺深部肿块，伴肿块的乳头paget’s病出现浸润性乳腺癌的可能性较大。预后较单纯浸润性乳腺癌差，需更为积极的综合治疗。
