An Experimental Study on Homoharringtonine Liposome and Glaucoma Filtration Surgery

Purpose: To observe the inhibitory action of homoharringtonine liposome during the healing process of wounds in the filtering sitesMethods: posterior sclerectomies were performed in 14 rabbits. Postoperatively one eye of each rabbit received subconjunctival injections of HH liposome and fellow eye received saline injection in a randomized masked fashion.Results; Fourteen days after operation the IOP of experimental eyes reduced significantly (P < 0.01) as compared with the controlled eyes, and the number of remaining filtering blebs increased noticeably (P< 0.05). Pathohistological examination revealed that the number of fibroblasts per square micron in the filtering sites and the thickness of the scars in the center of the filtering sites of the experimental eyes were less than those of the controlled eyes. No serious ocular toxic and side effects were found.Conclusion : This experiment suggests that homoharringtonine liposome can markedly inhibit the scar formation of filtering sites after glaucoma fi     

A Study on the Compliance of the Patients with Ocular Fundus Diseases

Purpose: To investigate the compliance of the patients with ocular fundus diseases with recommendation for follow-up examination after laser treatment, and the underlying reasons for non-compliance.Methods: 53 patients with ocular fundus disease were asked to fill in a questionnaire which includes the socio-demographic characteristics, fear of the fundus disease, conception of the laser treatment and the motivation for staying healthy. Variables were compared for the compliers group and the non-compliers group by chi-square test. Result; Of the 53 subjects, 35 were classified as non-compliers and 18 were classified as compliers. There was no statistically significant difference between the two groups on all selected socio-demographic factors, conception of the laser treatment and the motivation for staying healthy. Significant difference was found between the two groups on two of those items concerning the fear of the diseases (P<0. 05). About half of the participants showed the lack of knowledge about     

高频透热撕囊法在白内障手术中的应用

Practice protocol for the examination of specimens removed from patients with carcinoma of the urinary bladder, ureter, renal pelvis, and urethra

This article details a practice protocol for the examination and reporting of specimens removed from patients with carcinoma of the urinary bladder, ureter, renal pelvis, or urethra. It was created by a multidisciplinary task force of pathologists and oncologists established by the Cancer Committee of the College of American Pathologists. Documentation for the protocol was obtained from the previously published protocol, the medical literature, personal experience, and consultation with colleagues. After creation and review by the task force, the protocol was sent to 1000 randomly selected practicing pathologists as a survey. Their comments and suggestions were addressed in the final version. The protocol was approved by the Board of Governors of the College of American Pathologists.     

lschaemic heart disease: Non-invasive prediction of reperfusion and coronary artery patency by continuous ST segment monitoring in the GUSTO-I trial

In the GUSTO-I ECG ischaemia monitoring substudy, 1067 patientsunderwent continuous ST segment monitoring, using vector-derived12-lead (406 patients), 12-lead (373 patients) and 3-lead Holter(288 patients) ECG recording systems. Simultaneous angiogramsat 90 or 180 min following thrombolytic therapy were performedas a part of the prospective study in 302 patients. Infarct vessel patency was established as TIMI perfusion grades2 or 3 and occlusion as TIMI perfusion grades 0 or 1. Coronaryartery patency was predicted from ST trends up to the time ofangiography. Predictive values at 90 and 180 min after the startof thrombolysis were 70% and 82% for patency and 58% and 64%for occlusion, respectively. In retrospect, accuracy appearedgreatest (79–100%) in patients with extensive ST segmentelevation (400 µV), if both speed of ST recovery and extentof ST segment: elevation were taken into account. Although thethree recording systems differed considerably in signal processing,no significant difference in accuracy was demonstrated amongthese systems. We conclude that continuous ECG monitoring may help select highrisk patients without apparent reperfusion who may benefit fromadditional reperfusion therapy. As ST recovery may occur earlyafter the start of thrombolytics and accuracy of the test isrelated to peak ST levels, the use of on-line ECG monitoringdevices on emergency wards and cardiac care units is recommended.(Eur Heart J 1996; 17: 689–698)
