胸腔镜辅助小切口治疗自发性气胸22例分析

现代胸腔镜外科手术具有创伤小、疗效可靠、恢复快、手术时间短、并发症少等优点，并且通过小切口的应用，减少了一次性医疗器械的使用，降低了治疗费用。2001年6月～2004年10月，我院采用电视胸腔镜辅助小切口治疗自发性气胸22例，取得了满意的疗效，现分析报告如下。     

米索前列醇在人工流产术前的应用

人工流产术中，机械地扩张宫颈，可造成子宫颈组织的损伤，产生人工流产综合征及宫颈裂伤等并发症。我们在人工流产术前应用米索前列醇软化、扩张宫颈，使流产手术易于操作，大大减少了并发症，减轻了病人的痛苦，收到良好的临床效果，现将结果报告如下：     

引导组织再生术在牙周及根周病治疗中的应用

多种因素可致严重的根周及牙周病变 ,其特征是根周骨及牙周支持组织大范围吸收破坏 ,导致牙松动及功能丧失。近年来国内外已有学者用引导组织再生术成功地治愈了传统方法不能治愈的严重根周疾病[1] ,尤其是随着生物相容性更好的材料的不断出现[2 ] ,使引导组织再生术的应用更为简单实用。本科从 2 0 0 0年初起 ,选择性地对 3 0例牙周及根周病患者应用此法治疗 ,效果良好。现报道如下。1　材料与方法1.1　临床资料　患者 3 0例共 4 0颗牙 ,男性 16例 ,女性 14例 ,下颌第一磨牙根分叉Ⅱ度缺损 2 0例 ,下前牙牙周病 6例 ,根尖周病 4例。1.2　材…     

控制性降压在鼻内窥镜手术中的应用

目的 :观察控制性降压在鼻内窥镜手术中应用的意义。方法 :80例双侧鼻息肉、鼻窦炎患者 ,局麻、鼻内窥镜下行双侧鼻息肉摘除、全筛切除及开放上颌窦自然开口。其中 38例术中控制性降压 (降压组 ) ,另 42例作为对照。结果 :降压组术中出血 (6 1 39± 38 5 2 )ml,对照组出血 (140 12± 81 82 )ml,差异有显著性意义 (P <0 0 1) ;手术时间分别为 (4 9 2 5± 7 0 6 )min和(6 2 4 0± 9 90 )min ,差异有显著性意义 (P <0 0 1)。结论 :控制性降压可明显减少术中出血 ,缩短手术时间。     

非典型性儿童恶性淋巴瘤三例报告

恶性淋巴瘤是一组源于淋巴结或其他淋巴组织的恶性肿瘤,为提高对儿童恶性淋巴瘤的认识,减少误诊,现将我院1996～2000年收治的3例报告如下.     

大鼠脂肪干细胞复合胶原-壳聚糖-硫酸软骨素三维支架构建组织工程软骨

Objective To evaluate the character of the collagen-chitosan-chondroitin sulfate scaffold seeded with rat adipose tissue-derived stromal cells. Methods A dipose tissue were harvested from 6 weeks old Wistar rats and the stromal cells were harvested by type Ⅰ collagenase and then cultured in vitro. Type Ⅰ collagen was fully mixed with chitosan, freeze-dried and cross-linked with chondroitin sulfate, then freeze-dried again and sterilized by ethylene oxide. The pore diameter, water content, porosity of the scaffold were tested. The adipose tissue-derived stromal cells were digested, seeded into the plates, scaffold, and cen-trifuged into pellet, and then induced into cartilage. MTT detection for cell proliferation was done. After 3 weeks, the cell morphology, and cell proliferation and adhesion were observed, and chondrngenic differenti-ation was also analyzed. Results The pore diameter, water content, porosity tested for the scaffold showed an appropriate form. Cell proliferation showed faster in the scaffold and pellet culture system after 5 day, there was still cell proliferation in the scaffold system after 14 days but no obvious changes in the pellet cul-ture system; ceils on the scaffold proliferated densely showed by histological staining, but there was a scaf-fold structure residues in the inner layer. The finding of type Ⅱ immunohistochemistry stain showed that cells express strong positive for type Ⅱ collagen in the scaffold and pellet culture system whereas it was weakly positive in the plate culture system; the specific mRNA for cartilage, type Ⅱ collagen, aggrecan and SOX-9 were expressed in all three systems showed by RT-PCR, but type X collagen was expressed continu-ously in the plate culture system and expressed after 21 days in the pellet culture system, whereas it was not detected in the collagen-chitosan-chondroitin sulfate scaffold system. Conclusion The parameters of the collagen-chitosan-chondroitin sulfate scaffold were suitable in our study. The results suggested that it can promote the adipose tissue-derived stromal cells proliferation and chondrogenic differentiation better than the plate and pellet culture systems and maintain the phenotype of chondrocytes well; it is the optimal choice for cartilage tissue engineering in the future.
