AIM: To clarify the frequency of and changes in the cause of peptic ulcer bleeding. METHODs: This study retrospectively evaluated the out- and inpatients who underwent endoscopy between 2002 to 2008. The subjects were patients presenting with peptic ulcer bleeding. The details of these patients were obtained from their endoscopic reports and medical records. REsULTs: The rates of Helicobacter pylori (H. pylori ) infection were significantly low (P = 0.039), while the proportion of nonsteroidal antiinflammatory drugs (NsAIDs) users and vascular disease significantly increased over the period studied (P = 0.034 and P = 0.04, respectively). However, there was no significant difference in the proportion of low-dose aspirin users (P = 0.832).CONCLUsION: It's found that the primary cause of peptic ulcer bleeding changed from H. pylori infection to use of NsAIDs over the 7-year period of study. It seems that the number of low-dose aspirin users has increased with the increase in the proportion of vascular disease. It is necessary to take measures to prevent peptic ulcer bleeding among NsAIDs and low dose aspirin users.

Objective: Previous animal and clinical studies have shown that acupuncture is an effective alternative treatment in the management of stages I and II hypertension; however, information is still limited for stage III *** this study, we assessed the acute cardiohemodynamic and electrophysiological effects ofelectroacupuncture in the chronic atrioventricular block canine model with severe hypertension and heart failure(n=4).Methods: seven sessions of electroacupuncture were performed for 2 *** each session, needles were inserted at Renying(sT9) and Taichong(LR3), and then an electroacupuncture protocol consisting of 2 Hz frequency and 2 mA amplitude was carried out for 30 min with a Han’s acupoint nerve *** animals were anesthetized with pentobarbital in the initial and last sessions to estimate the acute and chronic cardiohemodynamic and electrophysiological effects of ***: Ventricular rate decreased during continuous stimulation at the first and the seventh sessions(Pssure increased and atrial rate decreased only during the first stimulation(Ps no significant change in the systolic blood pressure, diastolic blood pressure, cardiac output, total peripheral resistance, double product, and QRs width or QT interval during electrical stimulation in the first and the seventh *** was no significant difference in any time-matched variable between those two ***: These results suggest that electroacupuncture may rather expose a risk for hypertension crisis by a short application and that 7 sessions of treatment by electroacupuncture for 2 weeks might not be enough to lower the blood pressure in this special canine model.

A case of hyperkeratosis lenticularis perstans isease was studied istopathologically comparing early and old lesions. The age of the lesions were judged by both the patient’s history and direct observation. The histopathologic and immunophenotypic features of a new lesion were essentially in accordance with previous findings. However, the old lesion had obviously different pathologic features. These included the absence of epidermal atrophy and infiltrate in the upper dermis under the lesion. Ultrastructural studies revealed that the presence of many ormal-appearing membrane-coating granules in the keratinocytes of the old lesion, whereas the organelles were not found in the keratinocytes of the early lesion.
