Objective To study the clinical pathological significance and relationship of placental glutathione-s-transferase(GST-?) and p53 protein expression in the tissues of human lung carcinomas. Methods The expressions of GST-? and p53 in 60 cases of lung carcinomas were detected by the LSAB immunohistochemical method. Results The positive rates of GST-? and p53 protein expression in lung carcinomas were 56 67% and 31 67% respectively. The expressions of both GST-? and p53 had obvious relationship with the differential degree of the tumors(P

Objective To evaluate the methods of electrophysiological study (EPS) and radiofrequency catheter ablation (RFCA) for atrial tachycardia (AT) and the efficacy of RFCA. Methods Thirty-nine patients with AT were selected to undergo EPS and RFCA. The mean illness course was (4.5?1.6) years. Two patients had atrial septal defect, one had coronary artery disease, one dermatomyositis, and the other 35 patients had no structural heart disease. Identification of the earliest endocardial atrial activity (EAA) was based on the activation mapping recorded during AT. Results AT was induced spontaneously by atrial premature beats in 3 patients, and all other AT was inducible by atrial stimulation. Nine patients had other types of tachycardia combining with AT (including 5 patients with atrioventricular nodal reentrant tachycardia, 2 with atrial flutter and 2 accessory pathway). The site of AT was located by recording the EAA during AT and the region of successful FRCA. In 33 patients of successful ablation, the sites of AT were 9 near coronary sinus orifice, 5 near His bundle, 13 in right atrial lateral wall along crista terminalis, 2 in superior vena cava, 3 in atrial septum and 1 in right pulmonary vein. The successful rate was 81% (33/39) with all success of 9 other tachycardia. The mean fluoroscopic time was (16.4?2.1) minutes. None of patients had complications during and after ablation. Conclusions RFCA is an effective and safe treatment for AT. The activation mapping is the most effective method. Atrial septum and crista terminalis are the most common sites of AT.

Objective To explore the roles of insulin in the early treatment of acute brain injury and its administration methods.Methods 253 patients were randomly divided into the intensive insulin therapy group and the conventional therapy group.Infection rates,the short-term effect (APACHE Ⅱ assessment),and long-term efficacy (GOS prognosis) was compared between two groups.Results The results of the strengthen treatment group in the rate of infection (25.95％ vs 39.34％,x2 =5.17,P ＜0.05),the short-term effect (11.33 ± 7.66 vs 16.49 ± 14.97,u =3.42,P ＜ 0.05) and the long-term efficacy (40.46％,55.73％,3.82％ vs 25.41％,68.85％,5.74％,x2 =7.62,P ＜0.05) were significantly better than the conventional therapy group with the statistically significant differences (P ＜ 0.05).Conclusions The hypoglycemic effect,neuroprotective effect,regulatory role,and nutrition role of insulin occurred in the early treatment of acute brain injury.After acute brain injury,patients with hyperglycemia should be treated early with an enough volume,continuous,and uniform insulin.

Objective: To investigate the findings of coronary artery angiography in coronary artery disease patients with diabetes mellitus. Methods: The angiographic fingings of 153 coronary artery disease patients from 1995 to 1997 were reviewed. Among them, 33 were diabetic,23 were impaired glucose tolerance(IGT) and 97 were nondiabetic patients. Results: The age, sex, hypertension, hypercholesterolemia, smoking and the rate of myocardial infarction were the same among 3 groups. But the 2 vessel and 3 vessel disease were more frequent in diabetic group(66.7% ,30.3%) than in nondiabetic group (26.8%,19 6%). Two vessel disease were more frequent in diabetic group(66.7%) than in IGT group (13.1%). Single vessel disease were less frequent in diabetic group(3.0%) than in IGT group(52.2%)and nondiabetic group(53.6%)( P

Objective To investigate the clinical application of temporary balloon occlusion of the common iliac artery in performing cesarean section for patients with pernicious placenta previa and placenta accreta.Methods A total of five cases with ultrasound or MRI diagnosed pernicious placenta previa and placenta accreta were analyzed retrospectively.One of the cases was diagnosed Rh(-)blood type.Prophylactic temporary balloon implantation in bilateral common iliac arteries were carried out before cesarean section.Digital subtraction angiography ensured the position of balloon catheter and the catheter was fixed.The balloon was inflated immediately after the removal of the fetus.The balloon was removed at 6-8 hours after the cesarean section.The amount of blood loss,transfusion requirement,cesarean hysterectomy rate, and X-ray exposured time and dose during the procedure were recorded.Results Temporary balloon implantation in bilateral common iliac arteries in all five patients were obtained successfully.The blood loss was seen <500 mL in one patient and 500-1 000 mL in other four patients.Because of placenta implantation over depth of serosa and placenta percreta in one case,massive intractable hemorrhage occurred in short time,partial hysterectomy had to be carried out.The uterus was retained in other four cases.Conclusion The temporary balloon occlusion of the common iliac artery in performing cesarean section is a safe and effective technique,and it can reduce the amount of blood loss,transfusion requirement and secondary risk due to uncontrollable bleeding during surgery.

Intra-atrial re-entrant tachycardias (IARTs) are common late after heart surgery. Conventional mapping and ablation is relatively difficult because of the complicated anatomy and multiple potential re-entry loops. In this study we aimed to evaluate the electrophysiological characteristics and radiofrequency catheter ablation of atrial tachycardia (AT) induced by myocardial scar or incision. Methods In 6 patients (three male and three female, aged 33.3+ 11.8 years) who had AT related to myocardial scar or incision,electrophysiological study and radiofrequency catheter ablation (RFCA) were performed. Earliest activation combined with entrainment mapping was adopted to determine a critical isthmus. Results Re-entry related to the lateral atriotomy scar was inducible in 5 of6 patients. With entrainment mapping, the PPI (post-pacing interval)-TCL (tachycardia cycle length) difference was ＜30 ms when pacing at the inferior margins of the right lateral atriotomy scar. Among them, 3 patients had successful linear ablation between scar area to inferior vena cava, and 2 patients between scar area to tricuspid annulus. Re-entry involving an ASD patch was demonstrated in 1 of 6 patients. PPI-TCL differences ＜30 ms were observed when entraining tachycardia at sites near the septal patch. But linear ablation failed in terminating AT. There was no complication during procedure. No recurrence of AT related to incision was observed during follow-up except for the failed patient. Conclusion Under conventional electrophysiological mapping, adopting linear ablation from scar area to anatomic barrier, successful ablation can be obtained in patients with IRATs related to myocardial scar or incision.

Objective To evaluate the clinical application and therapeutic effect of interventional embolization in treating renal pseudoaneurysms. Methods The clinical data of 11 patients with renal pseudoaneurysm, who had received interventional embolization management at authors’ hospital, were retrospectively analyzed. The embolic agents used in the embolization procedure included conventional steel coil, gelatin sponge particles, PVA, etc. All the patients were followed up for 6-24 months. Results Single renal pseudoaneurysm was found in all the 11 patients. Clinically, symptom of bleeding was seen in 3 cases. The renal pseudoaneurysm was located at the upper (n=1), middle (n=4) and lower (n=5) renal artery of the kidney, and in one case the renal pseudoaneurysm was situated at the accessory renal artery. In performing renal artery embolization, pure PVA was used in one case, spring steel coil in one case, PVA together with spring steel coil in one case, and gelatin sponge combined with spring coil in 8 cases. After the embolization, the pseudoaneurysm was no more visualized, the contrast extravasation disappeared, and the parent artery was manifested as a residual root. During the operation the patients had no obvious discomfort. Within one week after embolization therapy, 2 patients developed hemorrhage, and their hemoglobin, white blood cell count and hematocrit were significantly increased. During the follow-up period, all patients showed no recurrence signs, and routine urine tests were normal. Conclusion For the treatment of renal pseudoaneurysms, interventional embolization is minimally-invasive, safe and reliable; this technique can maximally protect the normal kidney tissue, quickly control the bleeding and effectively save the life of patient. Therefore, it is worth promoting this treatment in clinical practice.
