ABSTRACT
Echinococcosis is an age-old disease that causes serious damage to the animal husbandry and the human health perennially. As a newly discovered species of Echinococus, E. shiquicus has the potential public health significance and could be a potential parasitic zoonosis. In this review, its etiology, life cycle, epidemiology, detection and diagnoses, public health etc. are discussed or summarized. Also, a series of comparisons among E. granulosus, E. multilocularis and E. shiquicus are made.
ABSTRACT
Objective To investigate the effect of glucagon-like peptide-1(GLP-1) in a dose related manner on glucose metabolism after 65% hepatectomy in rats.Methods We determined the serum glucose levels of hepatomized rats at 0,5,10,20,and 30 minutes after an intravenous glucose load(IVGTT,0.5 g/kg glucose) on the first postoperative day,and the changes of blood glucose,serum insulin and glucagon concentrations of hepatomized rats that received the volum load with normal saline or 0.3 nmol/kg GLP-1,0.45 nmol/kg GLP-1 respectively.Blood was drawn for determination of glucose(glucose oxidase),insulin,glucagon,and GLP-1(radioimmunoassay).Results The peak glucose and 30-minute glucose levels and the area under the curve(AUC 0-30) were significantly higher in the hepatomized rats compared to the control rats,which had not undergone any operation and received a same intravenous glucose load(0.5 g/kg glucose with normal saline)(P0.05).Nevertheless the peak glucose and 30-minute glucose levels and AUC 0-30 of the hepatomized rats that received with 0.45 nmol/kg GLP-1 were significantly lower compared to the rats that received the same volum load with normal saline or 0.3 nmol/kg GLP-1 respectively after liver resection.There was an increasing postoperative serum concentration of glucose,insulin,glucagon on the first day,then,the serum glucose concentration was significantly lowered after infusion of GLP-1 in rats undergoing hepatectomy(P

ABSTRACT
Objective To evaluate adbomen surgery in patients who are found to have poorly controlled or untreated hypertension before operation.Methods From January 1997 to December 1998,the perioperative clinical data of 531 patients with hypertension and undergoing abdomen surgery in our hospital were retrospectively analyzed.Results The incidences of perioperative hypertensive events were not significantly different,between controlled and uncontrolled patients with grade one and grade two (P>0.05).In grade three and systolic hypertension,certain perioperative complications in patients with poorly controlled hypertension were higher than in those with well-controlled hypertension(P<0.05).Conclusion The patients with grade on e and grade two hypertension are not at increased operative risk.In Patients with grade three and systolic hypertension,perioperative complications are increased and elective surgery should be postponed until their blood pressure is brought under 180/110 mmHg over 1 to 2 weeks.
