肿胀法超声抽吸术治疗腋臭83例疗效观察

目的观察肿胀法超声抽吸术治疗液臭的效果,寻找一种治疗腋臭的新方法。方法在腋窝毛发区皮下注入肿胀液80~100ml,经5mm大小切口将超声探头在腋部皮下组织快速移动,直到皮肤发红发热为止,再用负压抽吸被乳化的皮下组织加压包扎。结果83例受术者,术后6~12个月随访,效果良好者76例(91.5%),有效5例(6.25%),无效2例(2.25%)。结论肿胀法超声抽吸术治疗腋臭,操作简单,不留瘢痕,安全有效,是目前治疗腋臭较为理想的方法。     

Ultrasound evaluation of female urinary incontinence

Thirty women, 25 with incontinence and five asymptomatic volunteer control subjects, were evaluated urodynamically by a variety of techniques, including ultrasound cystourethrography. The ultrasound evaluation was found to be a helpful adjunct in diagnosis. In comparison with radiologic techniques it offers more safety, more comfort, more privacy, more viewing time, and less cost. Bladder and urethral morphology during voiding activity and the amount and direction of urethrovesical mobility are easily determined by utilizing ultrasound techniques.     

针刺穴位后超声监测胆囊收缩功能诊断胆囊炎探讨

目的:超声监测胆囊在针刺穴位后的收缩功能,借此对胆囊炎进行诊断。方法:对临床上已经确诊的51例胆囊炎病例进行超声检查,并测量相关径线,然后运用针刺相关穴位,使胆囊收缩,在针刺后10 min2、0 min、30 min分别进行超声检查,测量相关径线,然后运用胆囊容积计算公式计算出收缩前后胆囊容积,计算胆囊收缩功能。随机抽取与病例组年龄范围相同的25例健康成年人,在针刺穴位胆囊收缩前后进行超声检查,计算胆囊收缩功能,以进行正常对照。将病例组与正常对照组作两样本均数比较的t检验。结果:病例组针刺穴位后的胆囊收缩功能明显低于正常组(t<0.01)。结论:超声监测胆囊在针刺穴位后的收缩功能,可以对胆囊炎进行诊断,并且具有无损伤、痛苦小、病人易接受、可重复等优点,是一种很有发展潜力的中西医结合诊断方法。     

睾丸旁促结缔组织增生性小圆细胞肿瘤1例报告及文献复习

目的:探讨睾丸旁促结缔组织增生性小圆细胞肿瘤的临床、病理特征、诊断及治疗。方法:回顾分析1例睾丸旁促结缔组织增生性小圆细胞肿瘤的诊治及随访资料,并复习相关文献。患者,男,27岁,因阴囊内无痛性肿块4个月就诊。体检于左侧阴囊内可扪及囊性肿块,同侧睾丸不能扪及。行左侧睾丸根治性切除术,术后辅以化疗。结果:术中见左侧睾丸旁多发结节状隆起肿块,质偏硬;术后病理检查肿瘤细胞呈巢状或梁索状结构并埋没在增生的纤维结缔组织中;免疫组化显示瘤细胞具有上皮源性、间质性和神经源性等多向分化的特点。术后已随访3年无瘤生存,预后良好。结论:促结缔组织增生性小圆细胞肿瘤有特异的临床病理特征,好发于年轻男性,手术切除肿瘤联合化疗是治疗的主要方法,睾丸旁促结缔组织增生性小圆细胞肿瘤比腹腔型预后相对好。     

超声引导穿刺置入微导管法治疗恶性心包积液的评价

目的探讨超声引导下穿刺置入微导管法在恶性心包积液治疗中的价值.方法13例恶性心包积液在超声引导下进行心包穿刺,置入硬膜外麻醉导管（微导管）,通过导管抽出心包积液并注入化疗药物.结果13例均成功穿刺并顺利置入微导管,引流积液400～780 ml,平均530 ml.治疗后3、12、24个月存活率分别为92%（12/13）,78%（7/9）和60%（3/5）,无心包积液复发.结论超声引导穿刺置入微导管法治疗恶性心包积液安全、微创、有效、可行.     

金地鼠颊囊癌前病变的细胞增殖动力学研究

目的研究口腔上皮组织癌和癌前病变的细胞动力学变化特征。方法采用Ｓａｌｅｙ的ＤＭＢＡ涂布诱导法，建立金地鼠颊囊癌前病变模型，并用溴脱氧尿苷流式细胞动力学检测方法，对３０只叙利亚种金地鼠进行分组对照研究。结果涂药组光镜下的细胞病变程度随涂药时间延长而逐渐加重，而空白对照组无变化；ＦＣＭ检测显示涂药组与对照组在Ｓ期阳性细胞检出率存在显著差异。即使在光镜下表现为轻度不典型增生时，ＦＣＭ检测结果也有显著差别。结论金地鼠颊囊癌前病变具有细胞异常增殖的细胞动力学特征     

继发性肝癌的联合治疗

采用手术切除联合术后B超引导肝内门静脉区域化疗（简称PHPC）治疗胃肠道癌异时肝转移24例。随访4～54个月，结果：术后经3个疗程的PHPC，8例已存活肥18～48个月；13例分别经过2～11次的PHPC，已存活5～39p个月；另3例死亡。作者认为，对继发性肝癌采用手术切除配合术后B超引导的PHPC是一种延长患者生存期的有效联合治疗方案。     

Donor left ventricular hypertrophy increases risk for early graft failure

A review of factors contributing to early mortality after cardiac transplantation revealed that up to 25 % of deaths were due to primary graft dysfunction unrelated to rejection or infection. In light of this finding, evaluation of a donor heart with regard to its suitability for transplantation takes on added importance. In an effort to screen the suitability of donor hearts in the region covered by the Northwest Organ Procurement Agency (USA), all donors are evaluated by two-dimensional transthoracic echocardiography as part of the initial evaluation. A total of 110 donor echocardiograms were reviewed and an attempt was made to correlate the 30-day outcome with the parameters measured. An unexpected finding was that the presence of left ventricular hypertrophy in the donor heart was associated with an increase in the incidence of donor heart dysfunction compared with donors with normal echocardiographic profiles (33 % vs 3 %, P = 0.007).
