Objective: To determine the value of telomerase activity in urine exfoliated cells as clinical indicator of tumor presence, stage, and recurrence. Methods: The techniques of TRAP-PCR and TRAP-sliver staining were employed to detect telomerase activity in 73 patients with TCC before operation (study group) and 20 benign urothelial cancer patients (control group) and 21 normal individuals (normal group). Cytologic results were obtained simultaneously. The bladder tumor specimens were obtained from 73 patients during operation, and histologically evaluated for tumor content and grade. Results: Positive rate of telomerase activity detection in TCC patients (80.8%,59 of 73) was significantly higher than that of cytological examination (20.5%, 15 of 73). Positive telomerase activity was not found in 17 of 20 in control group and none was found in normal group. Analysis of the distribution of abnormalities with tumor stage revealed greater detection of high pathological stage (T 2-T 4) (89.7%, 26 of 29) compared with low stage (Tis-T 1) (75%, 33 of 44). Conclusion: Detection of telomerase activity in urine exfoliated cells may be a sensitive and effective marker in the diagnosis of TCC.

OBJECTIVETo investigate the influence of ozonated water on physical and chemical properties of vacuum sealing drainage (VSD) materials.

METHODSVSD materials (foam and sealing membrane) were immersed in 10 µg/ml ozonated water for 1 h twice daily for 8 days. The foam appearance and microscopic structure of the materials were observed, and tensile tests and Raman spectrum scan were performed assess the effect of ozonated water. Simulated VSD devices were prepared and tested for leakproofness under negative pressure after ozonated water treatment.

RESULTSzonated water treatment for 8 days caused no obvious abnormal changes in the foam appearance or microscopic structure of the materials. The maximum tensile load of foam before and after ozonated water treatment was 4.25∓0.73 kgf and 2.44∓0.19 kgf (P=0.000), the momentary distance when the foam torn before and after intervention was 92.54∓12.83 mm and 64.44∓4.60 mm, respectively (P=0.000). The corresponding results for VSD sealing membrane were 0.70∓0.58 kgf and 0.71∓0.08 kgf (P=0.698), and 99.30∓10.27 mm and 100.95∓18.22 mm (P=0.966), respectively. Raman spectroscopy revealed changes in only several wave intensities and no new chemical groups appeared within the scan range of 400-4000 cm(-1). The VSD device was well hermetic after treatment with ozonated water.

CONCLUSIONExcept for a decreased stretch resistance property of the foam, VSD materials display no obvious changes in physical and chemical characteristics after treatment with ozonated water for 8 days.

Objective To analyze the status of postoperative pain subjected to the patients undergone the common operation methods in Urology Department, in order to understand the characteristics of the postoperative pain in the patients and to provide a theoretical basis for better intervention and treatment of the pain. Methods In May 2016, a total of 179 patients in Urology Department of West China Hospital of Sichuan University of 6 diseases, including renal carcinoma, prostate cancer, bladder cancer, adrenal gland occupying, urethral stricture and renal cyst, were selected by purposive sampling method. The postoperative pain were retrospective assessed by six pain specialist nurses using the Visual Analogue Scale (VAS), and the time, degree and other characteristics of pain were analyzed. Results The most painful time of the patients undergoing renal surgery was about 4 hours after operation,and the degree of pain was mainly moderate or severe; the most painful time of prostate cancer was about 5 hours after operation, and the degree of pain was moderate; the most painful time of bladder cancer was 4 to 5 hours after surgery, and the degree of pain was severe; the most painful time after adrenal surgery was 4 hours after surgery, and the pain was moderate; the most painful time of urethral reconstructive surgery was 2 to 4 hours after surgery, and the pain was moderate; the most painful time of renal cyst decompression surgery was 2 to 3 hours after surgery, and the degree of pain was mild. The degree of pain at the most painful times of the six investigated kinds of diseases were different from those at 6 h, 12 h, 24 h and 48 h after operation, and the differences were statistically significant (P<0.05). Conclusions The degree of postoperative pain in patients with common urological diseases was mostly moderate or above. The VAS score of the pain reduces gradually in 6 to 48 hours after operation, and the most painful time of all patients is within 5 hours after surgery, which appears mostly after anesthesia resuscitation. Therefore, to establish a more accurate analgesic intervention according to the pain characteristics of these common operations is the key to the management of pain in the perioperative period in urology department.

Objective:To evaluate the anesthetic effect of remazolam when combined with sufentanil in elderly patients with liver cirrhosis and esophageal and gastric varices undergoing endoscopic sclerotherapy.Methods:A total of 150 cirrhotic patients with liver cirrhosis and esophageal and gastric varices, regardless of gender, aged 65-80 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, who underwent endoscopic sclerotherapy under non-intubated general anesthesia from March 2022 to September 2023 in our hospital, were selected and divided into 2 groups ( n=75 each) by a random number table method: sufentanil plus propofol group (PS group) and sufentanil plus remazolam group (RS group). Anesthesia was induced with intravenous propofol 1-2 mg/kg and sufentanil 0.1 μg/kg and maintained by intravenous infusion of propofol 4-10 mg·kg -1·h -1 in PS group. Anesthesia was induced with intravenous remimazolam 0.1-0.2 mg/kg and sufentanil 0.1 μg/kg and was maintained with intravenous infusion of remimazolam 0.5-2.0 mg·kg -1·h -1 in RS group. BIS values were maintained between 40 and 60 during operation in both groups. Endoscopy was placed when the patients lost consciousness (modified observer′s assessment of alertness/sedation score ≤1). Sclerosing agent laurosinol injection was injected into esophageal submucosal varices in both groups. The time to loss of consciousness and recovery of consciousness, intraoperative body movement and cardiovascular events, and postoperative hypoxemia and nausea and vomiting were recorded. The operator-patient satisfaction was assessed by the visual analogue scale. Results:Compared with PS group, no significant changes were found in the incidence of intraoperative bradycardia, time to loss of consciousness and time to recovery of consciousness( P>0.05), the incidence of intraoperative hypotension was significantly decreased, the incidence of postoperative hypoxemia and nausea and vomiting was decreased, and the satisfaction scores for operators and patients were increased in RS group ( P<0.05). No obvious body movement was found in the two groups. Conclusions:Sufentanil combined with remifentanil provides better anesthetic effect than sufentanil combined with propofol in elderly patients with esophageal and gastric varices undergoing endoscopic sclerotherapy.

Objective To develop a simple and effective method for monitoring cortical ischemia after temporary occlusion of the parent arteries during anterior circulation intracranial aneurysm surgery. Methods Fifty-two patients with anterior circulation aneurysm (58 aneurysms) received craniotomy from April to November 2008, and at the same time,cortical electroencephalograpby (EEG) and scalp EEG were monitored during the surgery.According to the international 10/20 electrode placement system, scalp electrodes were placed on O1, O2, P3, P4, T5, and T6 for monitoring the changes in the depth of anesthesia. A cortical strip electrode was placed on the cortical surface supplied by the artery that was possibly blocked during the operation, which was used to monitor the possible cortical ischemia. For patients who had cortical EEG suppression after the temporary occlusion of the parent arteries Were compared with the changes of scalp EEG. Whether there were ischemic events in the corresponding supply territory after vascular occlusion were observed after surgery. Results Of the 58 aneurysms, 40 aneurysms and 41 major arteries were occluded temporarily. After being occluded temporarily in 19 arteries of 18 patients, cortical EEG changed significantly,while scalp EEG did not change significantly. Only 9 patients had ischemic events in the corresponding supply territories after the occlusion in the cortical EEG significant change group. The changes in the depth of anesthesia had the consistent impact on cortical and scalp EEG. Conelusions Simultaneous monitoring of cortical and scalp EEG is a simple and effective method for monitoring cortical ischemia during anterior circulation intracranial aneurysm surgery, and may effectively identify the effect of anesthesia on EEG.

As the most effective treatment for acute ischemic stroke, intravenous thrombolysis can not only improve the outcome of patients, but also affect post-stroke depression (PSD) through direct or indirect mechanisms. Therefore, it is of great clinical significance to explore the effect of intravenous thrombolysis on PSD. This article reviews the characteristics of PSD, the possible impact and mechanisms of intravenous thrombolysis on PSD, and the prevention and treatment of PSD.
