Objective To evaluate whether to defer abdomen surgery in patients having poorly controlled or untreated hypertension before operation. MethodsThe perioperative clinical data of 531 patients with hypertension in our hospital from January 1997 to December 1998 was retrospectively analyzed. ResultsThe modility of perioperative hypertensive events was not significantly different, between controlled and uncontrolled patients with grade one and grade two（Pgt;0.05）. In grade three and systolic hypertension, certain complications in patients with poorly controlled hypertension were higher than in those with wellcontrolled hypertension（P＜0.05）. Conclusion The patients with grade one 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 24/14.7 kPa （180/110 mm Hg） over 1 to 2 weeks.
Objective To enhance survival rate and treatment effect for advanced gallbladder cancer (GBC). MethodsEighty cases of advanced GBC were treated surgically from January 1990 to June 2001.Seventyone cases had obstructive jaundice, 15 had palpable abdominal mass. Extended radical cholecystectomy was performed in 39 cases of advanced GBC in which the tumor invaded the surrounding organs or tissues but without distant metastasis. ResultsFollowup showed that the survival period was between 8 and 37 months (average 18.1 months), 1， 2 and 3year survival rates were 43.6%， 20.5% and 5.1% respectively. Palliative operations were performed in other 41 advanced GBC cases with distant metastasis. All of the patients died within one year. Conclusion This result suggests that extended radical cholecystectomy is effective for advanced GBC.
【Abstract】Objective To search for the drug that promots the hepatocyte regeneration after partial hepatectomy. Methods Quantitative morphometry technique, 3H-TdR in vivo test and arterial ketone body ratio (AKBR) were employed to evaluate the energy metabolism, DNA synthesis, and liver cell nuclear mitosis and hepatocyte regeneration of the residual liver tissue in rats after partial lobectomy when treated with human growth hormone (hGH) and placebo. Results After partial hepatectomy in the experimental group, liver cell nuclear mitosis，nuclear density, new liver cell numbers, AKBR and 3H-TdR in vivo test were much higher than those in the control group (P＜0.01 or P＜0.05). Conclusion hGH promotes the hepatocyte regeneration of the residual liver.
