Holter监测冠心病无痛性心肌缺血发作规律的研究

目的 探讨冠心病无痛性心肌缺血的发作规律。方法 对确诊的486例冠心病患者，进行24小时Holter监到，观察无痛性心肌缺血发作的次数、时间及其与活动状态的关系。结果 486例冠心病患者中发生无症状性心肌缺血者335例，共698次，累计时间为3526分钟。其中619次与活动有关。6：00—12：00为无痛性心肌缺血发作高峰期，在此期间共发作389次，累计时间为2100分钟。具有无痛性心肌缺血的冠心病患者的死亡率为13．02％，高于有症状的冠心病患者的4．72％。两组死亡率间差别有显著性意义(P＜0．05)。结论 无痛性心肌缺血的发作有一定的规律，掌握该规律对于指导临床治疗、降低心脏猝死及预防心肌缺血的发作有一定的作用。     

膝关节镜下膝后侧腔室联合手术入路的探讨

[目的]探讨在关节镜下膝关节后侧腔室联合手术入路的重要性和可操作性。[方法]经过前内侧、前外侧和股骨髁切迹以及后内侧、后外侧和后纵隔内切口联合入路分别入镜、入器械，进行膝关节后侧腔室的探查和手术操作。[结果]216例（239膝）应用联合入路探查和治疗，其中5例膝因关节僵硬操作失败；175例膝用于治疗后侧腔室疾病，膝关节后侧腔室手术视野显著改善，探查和手术操作完善，均达到手术目的。1例膝内侧隐神经不全损伤，没有腘后神经、腓总神经、腘后血管、交叉韧带等重要组织损伤。[结论]膝关节后侧腔室病变较多，是检查和治疗的重要部位，并非“技术盲区”。这种联合手术入路，手术风险低，具备可操作性，可以提高手术效率和质量，可作为膝关节镜下常规手术入路。

放射线联合p53基因及内皮抑素治疗小鼠前列腺癌皮下移植瘤

Objective To test the hypothesis that p53 gene therapy combined with endostatin can enhance tumor response to radiation therapy of RM-1 mouse xenograft prostate cancer and to investigate its mechanism. Methods A mouse prostate cancer model was established. Then mice with xenograft tumor were randomly divided into group A (control), B (radiation), C (radiation and rAdp53), D (radiation and rh-endostatin) and E (radiation and rAdp53 and rh-endostatin). On day 1, rAdp53 was injected intra-tumorously with 1 × 1010 vp per animal to group C and E. From day 1 to 14, rh-endostatin was given 15 mg/kg intraperitoneally daily to group D and E. On day 4 single fraction of 15 Gy was given to tumors in groups B, C, D and E. Normal saline was injected intra-tumorously or intraperitoneaUy accordingly as control. No treatment was done to group A. Tumor volume was measured daily. Samples were collected on Days 5, 10 and 15. Ki67, CD31, p53 and VEGF were detected by means of immunohistochemistry. Results (1) Radiation alone, radiation combined with intra-tumorous injection of Adp53 and/or intraperitoneal injection of rh-endostatin resulted in tumor growth arrest of RM-1 cells in vivo (P = 0.000). Radiation combined with both rAdp53 and rh-endostatin was the most effective treatment (P < 0.05). (2) All the four treatment groups had a decreased expression of mutant type P53 (P = 0.000). The expression of Ki67 in groups B and C were equal (P 0.05) and increasing (P = 0.000), respectively. Group D had a up-down-up curve (P < 0.05), but group E had a up-down one. On day 5 the expresion of VEGF in group E was the lowest (P < 0.05). An increased expression of MVD compared with the control was shown, and MVD in groups C, D and E were always higher than that in the control (P < 0.05). Conclusions The limitation of radiotherapy could be overcome by combination with beth p53 gene therapy and endostatin on the growth of mouse prostate cancer cell. Radiation, rAdp53 and endostatin have their own role but they can be interacted with each other.     

乳腺良恶性病变的磁共振T2*W首过灌注成像与血管生成相关性研究

Objective： To study the diagnostic value of T2^＊-weighted first-pass perfusion imaging in breast tumors. Methods： We analyzed the magnetic resonance imaging （MRI） information along with the pathological and immunohistochemistry results. Magnetic resonance imaging was performed in 28 patients with breast tumor. The time to signal intensity curves were generated according to the T2^＊-weighted first-pass perfusion imaging. The curve＇s maximal signal intensity drop rate and maximal signal intensity decrease time were analyzed and compared with the pathological diagnoses after surgery. Results： Malignant breast lesions showed higher maximal signal intensity drop rate （44.69% ± 17.07 vs. 17.22% ±7.49, P 〈 0.001） than benign lesions, but there was no significant difference of maximal signal decrease time between those two lesions （23.94 s ± 4.92 vs. 20.02 s ± 6.83, P 〉 0.05）. Conclusion： The T2^＊-weighted first-pass perfusion imaging has enough sensitivity and specificity in breast tumor diagnosis.
