Purpose:To investigate the expression of vascular endothelial growth factor (VEGF) and its relationship with proliferating cell nuclear antigen (PCNA) and the prognosis of colon cancer patients. Methods:The VEGF and PCNA as well as p53 expression were examined using immunohistochemistry with monoclonal antibody in 70 surgical samples of colon cancer. Results:VEGF expression was positive in 91.43% of the colon cancer patients. It had a positive relation with the p53 expression (rs=0.417, P

Objective To investigate the effects of Tongxinluo on C reactive protein(CRP)and clinical prognosis in patients after coronary stenting. Methods From January 2003 to December 2004, 132 patients in our department diagnosed as coronary artery disease(including acute myocardial infarction, unstable angina pectoris and stable angina pectoris)were divided into two groups: Tongxinluo group and control group. The control group received routine treatment, while Tongxinluo group based on routine treatment was administrated with Tongxinluo capsule in combination for 6 months. Results CRP level was much lower in Tongxinluo group together with apparent decrease of the major adverse cardiac event(MACE)rate in 6 months' follow-up than those of the control group, but showing no difference in coronary arterial restenosis between the two groups at 6 months after coronary stenting. Conclusion Tongxinluo has favorable effects to decrease the CRP level and improve clinical efficiency together with prognosis for patients after coronary stenting.

The current problems of pharmacology teaching in nursing in 3-year program colleges lie in that the teaching ideas drop behind;course orientation is vague;the development of text books lags;the contents lack characteristics;and there is no clear aims in the practice teaching.So,it is essential to make the teaching evolution.First,according to the post needs,the orientation of the courses should be definite,and new ideas about the curriculum should be set up.Meanwhile,the development of text books should be speeded up and the teaching contents should be optimized.Then,practice teaching needs to be improved,and cultivation of their comprehensive competence should be enhanced.To improve the students’professional qualities,emphasis on the penetration of humanities should be paid attention to.

Objective To evaluate the effect of Tirofiban on CRP levels in patients with acute myocardial infarction (AMI) after primary emergency percutaneous coronary intervention (PCI). Methods Eighty-four AMI patients admitted on emergency were randomly divided into two groups: (1) early-treated group (n=45), immediately receiving Tirofiban intravenously on admission and (2) late-treated group (n=39), receiving Tirofiban intravenously after coronary angiography was performed. TIMI grading before and after PCI in beth groups were compared, CRP levels before and three days after PCI were estimated. The major adverse cardiovascular events (MACEs) occurred during hospitalization and following-up period of three months were recorded. Results Before PCI, TIMI grade 3 forward flow rate in early-treated group was significantly higher than that in late-treated group, while no significant difference existed between two groups after PCI. Three days after PCI, CRP level in early-treated group was markedly lower than that in late-treated group. During hospitalization, the occurrence of MACEs in early-treated group was lower than that in late-treated group, while no marked difference was found between two groups during the following-up period of three months. Conclusion In treating AMI patients with primary PCI, Tirofiban should be used as early as possible, which is safe and effective for PCI and can also significantly improve forward blood flow in target vessels, decrease the ClIP level and reduce the occurrence of MACEs during hospitalization.

Objective To assess the value of intra-aortic balloon pump (IABP) support in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) undergoing percutaneous coronary intervention (PCI). Methods The clinical data of 41 patients with AMI complicated by CS receiving emergency PCI with IABP support were retrospectively reviewed, and 47 patients receiving emergency PCI without IABP support at the same time were included as the control group. Left ventricular function was evaluated in the 2 groups at 2 weeks and at 3 months after the operation respectively. The incidence of MACE was compared between the 2 groups at 30 days and also at 3 months after the operation. Results Patients receiving IABP support had greater improvement in left ventricular function at 2-week and 3-month after operation (43.8?8.2% vs 39.4?5.9%, 45.5?6.6 vs 40.6?4.6%, both P

Objective To estimate the value of the Angio seal (Vascular Cloure Device, St Jude Medical) in femoral artery closure after CAG (coronary angiography) or PCI (percutaneous coronary intervention). Methods From Oct 2002 to Oct 2003 316 patients received CAG or PCI at our hospital They were divided into group A (150 patients) and group B (166 patients) The Angio seal was useded in group A to close the puncturing spot of femoral artery, and the side of the body punctured was trigged for 4 hours Common hemostasis was adopted in group B Results As compared with group B, time to hemostasis and time to ambulation were notably decreased and groin hematoma and time to bleeding disposed at the puncture site were markedly reduced in group A Conclusion Safe and effective, the Angio seal may be widely adopted in clinical practice

Objective To evaluate the clinical value of laparoscopic uItrasonography ( LUS) in u-rinary laparoscopic surgery .Methods In 6 cases of urological laparoscopic surgery , laparoscopic ultra-sound examination were taken , including 3 cases of simple renal cysts , 1 case of adrenal pheochromocyto-ma, 2 cases of hamartoma , were excised under the LUS guidance and the results were compared with the traditional simple laparoscopic surgery .Results With laparoscopic uItrasonography guidance , the bounda-ry and blood supply of cyst or tumor could be shown more clearly compared with trans -abdominal ultrasound . We could differ the tumors from dilated pelvis and renal calices , So the damage to the collecting system and renal blood vessels were avoided .With LUS guidance , tumors were excised more completely , so that re-mained tumor tissues would be avoided and normal renal tissues would be protected .Conclusion LUS may provide more precise surgical information and may play an important role guiding laparoscopic operation in urinary surgery .

Objective To obtain a clear and qualified compound glycyrrhiza oral solution by using NaSO3 and EDTA as stabi-lizers and Tween80 as solubilizer so as to solve the problem of morphine content instability. Methods NaSO34g and EDTA 0.6 g as stabilizers,and Tween803 g as solubilizer were added in the traditional method. The pH of the solution was adjusted to 8.0. Then the solution was obtained and filled in the brown polyester bottle. Results The preparation was clear,qualified and the content of mor-phine was steady. Conclusion The improved method is feasible,simple,stabilized and suitable for manufacturing.

Objective:To analyze the independent and comprehensive effects of the sites and mechanisms of middle cerebral artery(MCA)occlusion on cerebral infarction patterns and the National Institutes of Health Stroke Scale (NIHSS)scores andto investigate the possible related mechanisms and their potential values to the selection of patieras for thrombolysis.Methods:Sixty-six patients with new cerebral infarction caused by MCA occlusion were enrolled.The sites of MCA occlusion were classified into the origin of the MCA(type Ⅰ),the MCA trunk distal to the lenticulostriate arteries(type Ⅱ)and the branches of the MCA(type Ⅲ):the mechanisms of cerebral infection were categorized as thrombotic and embolic.Cerebral infarction lesion patterns were determined according to diffusion-weighted image(DWI).NIHSS scores were evaluated within 24 hours after stroke onset.The independent and comprehensive effects of the sites and mechanisms of MCA occlusion on cerebral infarction lesion patterns and the NIHSS were analyzed.Results:Cerebral infarction involved a larger range and NIHSS scores were higher in patients with occlusion at the origin of MCA and embolic occlusion of the MCA trunk distal to the lenticulostriate arteries.The analysis of the combination of the sites and mechanisms of occlusion could conduct further stratification for patients with cerebral infarction caused by MCA occlusion compared with univariate analysis.Conclusion:The analysis of the combination of the sites and mechanisms of occlusion better stratifies patients with cerebral infarction caused by MCA occlusion.It may be help to select patients for thrombolytic therapy.
