ABSTRACT
Objective To study the method and nursing measurements of the detection of portal venous pressure. Method The implantable drug delivery system was performed during the operation in 31 patients with liver cancer. The direct dynamic observation was performed by using the system and the corresponding nursing measurement was given. Result The measurement of portal venous pressure was successful performed 251 times in 31 cases with liver cancer and no complications were taken place. Conclusions The dynamic observation of portal venous of pressure by using the implantable drug delivery system was simple. Safety and could be repeated and could easily be receipted by the cases, the nurses skilled measured the key points of nursing and actively prevented the complications was taken implant role in increasing the rate of success of detection .
ABSTRACT
Objective To study the effect of forpart operation on reducing death rate of patients with severe acute pancreatitis.Methods A retrospective study was conducted to analyze 56 patients with severe acute pancreatitis.Results Among 56 patients,11 cases died,5 patients died from MODS after operation in 24 hours;6 patient died of abdominal infection etc;and other patients were cured.Conclusion To patients with severe acute pancreatitis,making use of different method according as clinic sign in appropriate time can reduce death rate and obtain satisfactory treatment outcome.
ABSTRACT
Objective To evaluate the effect of cholecystokinin receptor antagonist proglumide on the pancreatic function of post-ERCP. Methods The frequency and mortality of acute pancreatitis of post-ERCP, and the plasma contents of cholecystokinin-octapeptide(CCK-OP) and amylase were compared among control group(group C),octreotide treatment group(group O) and proglumide treatment group(group P). Results The frequency of acute pancreatitis of post-ERCP in group C was 13.6%(3/20), which was significantly higher than that in Group O(5%,1/20) and group P (4.0%,1/25)(P0.05). The contents of plasma CCK-OP were significantly lower in group P than those in groups O and C 4h after ERCP (P0.05). Conclusion Proglumide could inhibit the action of cholecystokinin-octapeptide, and decreas the hyperamylasemia and the frequency of pancreatitis of post-ERCP as octreotide.
ABSTRACT
Objective To observe the effect of somatostatin (SST) on the expression of metalloproteinase-2(MMP-2) and tissue inhibitor matrix metalloproteinase-2(TIMP-2) of implanted tumor in nude mice after partial hepatectomy.Method Nude mice were divided into group A(n=10) implanted by human hepatocellular carcinoma(HCC),group B(n=10, partial hepatectomy) and C(n=10,HCC implantation after liver resection). SST(250 ?g/kg,b.i.d) was given intraperitoneally in group C. Mice were sacrificed on 35th d, tumor was measured, the expression of MVD.MMP-2 and TIMP-2 was detected by immunochemical staining and quantitative image computer-analysis. Results In group B, the weight and volume and expression of MVD.MMP-2 of tumor tissue was markedly incressed than in group A(P
