Objective To compare the efficacy and safety of prourokinase,reteplase and urokinase on the patients with acute ST -segment elvation myocardial infarction.Methods According to random number table,the eligible patients with acute ST -segment elvation myocardial infarction were randomly divided into prourokinase group (50mg,n =34),reteplase group (36mg,n =42)and urokinase group (1 500 000IU,n =32).The patency of infarct related coronary artery was estimated by coronary angiography at 90min after administration of thrombolytic agents.The adverse reaction was also observed including bleeding and the major adverse cardiac events(MACEs).Results The patency of culprit vessel in the prourokinase group was 76.50% (≥TIMI 2 flow),which in the reteplase group was 83.30% (≥TIMI 2 flow),and which in the urokinase group was 53.10% (≥TIMI 2 flow),respctively.Both of prourokinase group and reteplase group were higher in the patency than theurokinase group(χ2 =8.27,P =0.004). The MACEs and bleeding adverse reaction(prourokinase group 17.65%,reteplase group 28.57%,urokinase group 42.19%)showed that security of prourokinase group was securer than reteplase group and urokinase group(χ2 =6.36,P =0.012).Conclusion Both of prourokinase and reteplase are effective for the patients with acute myocardial infarction with ST -segment elvation,and prourokinase is safer.

Objective To investigate the clinical value of para-aortic lymphadenectomy in patients with cervical cancer in stage Ⅰ B2 and Ⅱ A2.Methods One hundred and six patients with cervical cancer in stage Ⅰ B2 and Ⅱ A2 were assigned into two groups:control group(55 patients,radical hysterectomy and pelvic lymphadenectomy) and study group (51 patients,radical hysterectomy,pelvic lymphadenectomy and para-aortic lymphadenectomy).Postoperative radiotherapy or chemotherapy was conducted appropriately.Intraoperative and postoperative characteristics,recurrence rate,survival rate were compared between two groups.Results In study group,the recurrence rate was 15.7 ％ (8/51),and in control group,the recurrence rate was 38.2％(21/55),there was significant difference (P ＜ 0.05).No significant difference were observed in the complication incidence [27.5％ (14/51) vs.30.9％ (17/55)],blood loss [(326.1 ± 59.1) ml vs.(316.1 ± 51.2) ml] and pelvic lymph node-positive rate [56.9％ (29/51) vs.58.2 ％ (32/55)](P ＞ 0.05).The incidence of para-aortic lymph node metastasis was 17.6 ％ (9/51).Positive correlation was observed between the number of the pelvic lymph node metastasis and para-aortic lymph node metastasis (P ＜ 0.01).Conclusions In cervical cancer,the number of the pelvic lymph node metastasis was associated with para-aortic lymph node metastasis,abdominal aortic lymphadenectomy in radical surgery for cervical cancer is safe and feasible and can improve the prognosis of the patients.

Medical imaging is an important auxiliary means of disease diagnosis. In the process of diagnosis, diseases are usually presented in a static way, which is one of the characteristics of imaging diagnosis. However, this static representation of diseases imposes certain limitations, which can, to some extent, lead to the loss of medical humanities. Therefore, it is very important for imaging diagnostic doctors to correctly use philosophical thinking to understand, analyze, and solve problems. The reinforcement of philosophical thinking in imaging diagnosis entails commitment to the "patient-centered" perspective in medicine as well as the integration of comprehensiveness, regularity, and proactivity. This not only effectively trains the diagnostic thinking of imaging diagnostic doctors but also improves their humanistic quality, thereby addressing the problems associated with these limitations. This allows the diagnosis to be both technically accurate and emotionally attuned.
