术中应用丝裂霉素C预防翼状胬肉术后复发的疗效观察

OBJECTIVE: To explore the feasibility of intraoperative application of mitomycin C (MMC) in pterygium and observe the ultrastructure change of pterygium with or without intraoperative application of MMC. METHODS: Sixty two eyes of 57 patients with primary pterygium were randomly divided into MMC group and control group, 29 patients (32 eyes) in MMC group underwent transposition with intraoperative application of MMC (0.4 mg.ml-1 for 1 minute), whereas 28 patients (30 eyes) in control group underwent transposition. The recurrence rate, complications and side effects were observed and compared between the two groups. The ultrastructure of pterygium with or without intraoperative application of MMC was studied with transmission electron microscopy. The mean follow-up was(7.6 +/- 3.4) months (1-13 minths). RESULT: Eleven eyes of the 30 eyes in control group (36.%) showed recurrence, whereas only 2 of 32 eyes (6.3%) in MMC group showed recurrence (P < 0.005). No severe complication and side effect appeared during the follow-up. Most of fibroblasts in pterygium that underwent intraoperative MMC occurred the change of rough endoplasmic reticulum (RER) dilatation. CONCLUSION: Intraoperative MMC appears to be an effective treatment in preventing recurrence of primary pterygium. The fibroblasts in pterygium have RER dilatation after application of MMC for 1 minute during the operation.     

椎基底动脉短暂缺血性眩晕患者脑血流量与脑干听力诱发电位的关系研究

为探讨椎基底动脉短暂缺血性眩晕 (VBTIV)患者的脑干听力诱发电位 (BAEP)与脑血流量 (CBF)和病理改变的关系 ,对 6 5例 VBTIV患者 (患者组 )作磁共振血管成像 (MRA)、经颅多普勒 (TCD)和 BAEP检查 ,对 2 6例对照组患者作 MRA和 TCD检查。结果 :MRA显示患者组 5 0例血管病理改变明显 ,1 5例改变不明显或无改变 ;对照组脑血流量为 1 1 2 .3～ 2 78.9ml/ min(2 s) ,较患者组 48.0～ 2 6 2 .0 m l/ min高 (P<0 .0 1 ) ,患者组 1 5例脑血流量下降 ,5 0例脑血流量正常 ;患者组 BAEP异常 47例 (72 .3% ) ,其中 ,1 5例脑血流量下降者 ,1 4例(93.3% ) BAEP异常 ,比 5 0例脑血流量正常者中的 33例 (6 6 % ) BAEP异常高 (P<0 .0 5 ) ;5 0例血管病理改变明显者 ,BAEP异常 40例 (80 % ) ,比 1 5例血管病理改变轻或无改变者中的 7例 (43.3% ) BAEP异常高 (P<0 .0 5 ) ,说明BAEP与 CBF和血管病理改变密切相关     

Changes of type I collagen in the lungs of rats with hypoxic pulmonary hypertension]

The changes of type I collagen in the lung tissues of rats with hypoxic pulmonary hypertension (HPH) and its relationship to the mean pulmonary arterial pressure (mPAP) were investigated. The blood dynamic indexes of pulmonary circulation were measured by using Swan-Ganz. The distribution of type I collagen in pulmonary arteries, bronchi and plumonary interstitial was observed by using streptavidin peroxidase method (SP). The morphologic changes of small pulmonary arteries and the level of type I collagen were determined by image pattern analysis technique and gray scale scanning, respectively. The results showed, compared with the controls, mPAP of the hypoxic rats elevated (from 2.12 +/- 0.25 to 3.95 +/- 0.43 kPa, P < 0.01), their small pulmonary arteries, walls thickened (MT% from 16.35 +/- 2.64 to 35.83 +/- 3.55, MA% from 26.83 +/- 3.40 to 59.68 +/- 4.90, P < 0.01) and lumen narrowed. The distribution of type I collagen was mainly in the external layer of pulmonary arterial walls; the positive degrees of gray scale scanning increased and had a positive linear relationship to the mPAP and MT%. These findings suggest that the increase of type I collagen contents in pulmonary arteries is closely related to the development of HPH.
