开颅术后张力性气颅

报告１９８８年１２月～１９９２年１２月开颅术后张力性气颅５例，男４，女１．５例中３例治愈，２例死亡。开颅术后张力性气颅产生的主要原因是颅内占位性病变切除后，脑脊液丢失，使颅内压降低，甚至呈负压状态，外界的气体从切口进入颅内的腔隙，ＣＴ扫描或颅骨Ｘ线平片可以确定诊断，钻孔置管排气是活疗张力性气颅的有效方法，作者探讨了预防此种并发症发生的措施。     

畸形肾结石的冲击波碎石术

畸形肾结石是当今泌尿外科的难题之一，在治疗上一直存在争议。自体外冲击波碎石术（SWL）问世以来，随着治疗例数和经验的不断积累，目前已经逐渐达成共识：畸形肾结石的冲击波碎石是一种行之有效的治疗方法，但也有较大的局限性。本在温习新近献的基础上，结合畸形肾结石的形态特点和诊断要点，概要介绍相关冲击波碎石的一些准则、观点和技术。

伽玛刀治疗高危前列腺增生症的临床应用

目的探讨伽玛刀在不适合开放手术或经尿道电切术的高危前列腺增生患者治疗中的应用。方法采用深圳奥沃公司生产的OUR-QGD型立体定向全身伽玛刀治疗20例高危前列腺增生患者。应用国际前列腺症状评分(IPSS)、前列腺重量、最大尿流率(Qmax)、残余尿量作为评价指标。观察上述数据在治疗前后的改变及其临床意义。结果术后随访6个月,IPSS评分由治疗前29分降至19.6分(P<0.01)。前列腺重量平均值均由治疗前的(56.4±4.4)g减少至(54.8±4.3)g(P>0.05)。最大尿流率平均值由治疗前的(6.7±1.8)ml/s增加至(11.5±1.7)ml/s(P<0.01),残余尿量平均值由治疗前的(85.1±27.8)ml降至(50.9±15.6)ml(P<0.01)。结论立体定位体部伽玛刀治疗高危前列腺增生症患者具有简便、安全、无创、痛苦小、并发症少、疗效好,可不需住院等优点,对不愿意接受手术或不宜手术的高危前列腺增生患者不失为一种良好的治疗方法,但费用较高。     

影响同种异体肾移植受者勃起功能障碍的因素与治疗选择

性生活质量是肾移植受者生活质量的重要内容之一,随着肾移植受者存活率的提高,男性受者性生活质量,尤其是勃起功能已经受到医学界和移植肾受者的广泛关注。现有的资料表明男性肾移植受者勃起功能障碍(ED)的患病率为35.8%~78.3%;影响男性受者ED的因素有年龄、透析时间、手术方式、血红蛋白含量、精神心理因素、免疫抑制药物、糖尿病等。在对男性肾移植受者ED的治疗中万艾可是有效、安全的,在口服药物治疗失败后也可选择阴茎海绵体血管活性药物注射或阴茎假体植入术,但是三件套假体应该避免使用。     

人毛乳头细胞条件培养液治疗斑秃的临床观察

目的：人毛乳头细胞条件培养液治疗斑秃患者的临床观察。方法：用人毛乳头细胞条件培养液治疗100例斑秃患者，并分别选择其中53例和30例作去炎松组和空白组自身对照。结果：人毛乳头细胞条件培养液组、去炎松组和空白组治愈率分别为75％、51％、10％，有效率分别为97％、72％、30％，人毛乳头细胞条件培养液组其治愈率和有效率均明显高于去炎松组和空白组（P〈0．05）。结论：人毛乳头细胞条件培养液对斑秃患者有明显的治疗作用。     

Trehalose protects against ocular surface disorders in experimental murine dry eye through suppression of apoptosis

The disaccharide trehalose is a key element involved in anhydrobiosis (the capability of surviving almost complete dehydration) in many organisms. Its presence also confers resistance to desiccation and high osmolarity in bacterial and human cells by protecting proteins and membranes from denaturation. The present study used a novel murine dry eye model induced by controlled low-humidity air velocity to determine whether topically applied trehalose could heal ocular surface epithelial disorders caused by ocular surface desiccation. In addition, the efficacy of 87.6 mM trehalose eyedrops was compared with that of 20% serum, the efficacy of which has been well documented. Mice ocular surface epithelial disorders were induced by exposure of murine eyes to continuous controlled low-humidity air velocity in an intelligently controlled environmental system (ICES) for 21 days, which accelerated the tear evaporation. The mice were then randomized into three groups: the control group received PBS (0.01M) treatment; a second group received 87.6 mM trehalose eyedrops treatment; and the third group received mice serum eyedrops treatment. Each treatment was administered as a 10 μl dose every 6 h for 14 days. The resultant changes in corneal barrier function and histopathologic examination of cornea and conjunctiva were analyzed and the level of apoptosis on the ocular surface was assessed using active caspase-3. After 14 days of treatment, the corneal fluorescein staining area, the ruffling and desquamating cells on the apical corneal epithelium, as well as the apoptotic cells on ocular surface epithelium had significantly reduced in eyes treated with trehalose compared with those treated with serum and PBS. In contrast, after 14 days of treatment, improvements in the thickness of the corneal epithelium, the squamous metaplasia in conjunctival epithelium and the number of goblet cells of the conjunctiva were less marked in eyes treated with trehalose compared with serum. These results demonstrated that trehalose could improve the appearance of ocular surface epithelial disorders due to desiccation through suppression of apoptosis. Trehalose produces some of the same responses as serum upon topical application and can maintain corneal health.     

远隔性小脑出血

远隔性小脑出血极为罕见，可见于多种类型的神经外科手术，一般出现在手术远隔部位，多分布于单侧或双侧小脑沟、蚓部，小脑上部出血也较为多见。远隔性小脑出血总体预后良好，病死率约为10％～15％。     

重视膀胱癌淋巴管浸润和淋巴结转移的研究

转移是膀胱癌患者死亡的主要原因,且早期以淋巴结转移为主。T2 期膀胱癌约 50%淋巴管内有癌细胞,T3 期几乎全部淋巴管内有癌细胞。残存的肿瘤细胞淋巴管浸润是肿瘤切除术后复发的根源,明显的淋巴结转移更是患者预后不良的重要危险因素。然而膀胱癌淋巴管浸润和淋巴结转移的
