Purpose of ReviewWith increased understanding of the biomechanical function of the acetabular labrum, more attention has been directed towards surgical techniques that preserve or restore normal joint anatomy. While labral repair has been shown to produce superior outcomes to labral debridement, repair is not always possible in the setting of severe labral intrasubstance tearing or deficiency. These patients were previously left without suitable arthroscopic treatment options.Recent FindingsLabral reconstruction is an emerging procedure that has been shown to offer promising outcomes for traditionally difficult-to-treat hip pathology. Short- and mid-term follow-up studies have consistently demonstrated significant improvement in patient-reported outcomes, function, and patient satisfaction postoperatively, often despite less favorable preoperative characteristics.SummaryLabral reconstruction is a viable arthroscopic treatment option that has been shown to reliably produce clinically meaningful results in patients with severe labral pathology that is not amenable to repair/refixation or augmentation. 相似文献

We present a patient with surgical stage I endometrial cancer who experienced laparotomy wound recurrence 4 years after primary treatment. She was treated successfully by complete surgical resection of recurrent tumors and chemotherapy. A 62-year-old white female with laparotomy wound recurrence of endometrial carcinoma with small-bowel involvement and concomitant subcutaneous metastasis in the abdominal wall underwent complete surgical resection of metastatic tumors followed by six cycles of chemotherapy consisting of paclitaxel (175 mg/m2) and carboplatin (area under the curve 5). Since 24 months after resection of recurrence, she has no evidence of disease recurrence. Endometrial carcinoma with laparotomy wound recurrences, especially those with concomitant metastases, can be successfully treated by complete surgical resection followed by chemotherapy consisting of paclitaxel and carboplatin. 相似文献

预激态补骨脂素抑制 K562细胞增殖的实验研究 总被引:6,自引:0,他引:6
本研究的目的是观察预激态补骨脂素对K562细胞增殖的影响,为补骨脂素的临床应用提供实验依据。取预激态补骨脂素和晚激态补骨脂素处理的细胞,在培养后检测台盼蓝拒染细胞数和白血病细胞集落,并对它们在台盼蓝拒染细胞抑制率(TBIR)、细胞增殖抑制率(CPIR)和集落形成抑制率(CFIR)方面的差异进行比较。结果表明:预激态补骨脂素对K562细胞增殖有抑制作用;随着预激态补骨脂素浓度的增加,其抑制作用也随之增强;预激态补骨脂素与晚激态补骨脂素的TBIR、CPIR、CFIR各值比的差异不显著;为使预激态补骨脂素要充分发挥对K562细胞的抑制作用,补骨脂素的紫外线照射时间应在10分钟以上;与K562细胞作用时间也应大于12小时;抑制作用会因预激态补骨脂素预激后搁置时间的延长而下降,在6小时内作用最强。结论:预激态补骨脂素和晚激态补骨脂素对K562细胞的增殖均表现出抑制作用,有望作为临床的抗肿瘤用药。 相似文献

Introduction
Although inhalation of 80 parts per million (ppm) of hydrogen sulfide (H2S) reduces metabolism in mice, doses higher than 200 ppm of H2S were required to depress metabolism in rats. We therefore hypothesized that higher concentrations of H2S are required to reduce metabolism in larger mammals and humans. To avoid the potential pulmonary toxicity of H2S inhalation at high concentrations, we investigated whether administering H2S via ventilation of an extracorporeal membrane lung (ECML) would provide means to manipulate the metabolic rate in sheep. 相似文献98.

Intravascular tumors: transvenous biopsy 总被引:1,自引:0,他引:1
A technique is described for transfemoral biopsy of intravenous tumors. Positive results were obtained at biopsy in three patients who had an intraluminal mass in the inferior vena cava and in one patient with a mass in the iliac vein. Transvenous biopsy is helpful in obtaining a histologic diagnosis and provides an alternative method to surgery or percutaneous transabdominal needle biopsy. 相似文献
