Résumé
Objective To study the proper perioperative nursing methods about patients who have accepted the procedure of prolapsed hemorrhoid operation. Methods Careful and finished before operative evaluation and the perioperative nursing cares were used for patients.Results Only one patients dead for lung cancer,others had successful operation without any complications.Conclusions Careful nursing intervention can effective reduce the incidence rate of postoperative complication for PPH,and then improve the quality of life for patients.
Résumé
Objective:To explore and sum up diagnostic features and therapy for colorectal carcinoma with hepatic metastasis.Methods:48 cases of colorectal carcinoma with hepatic metastasis treated from Oct.1989 to Oct.1997.Results:The accuracy rates of ultrasound and CT were 18.2%,53.3% respectively.Of the 48 cases,10 cases underwent hepatectomies,10 cases ethanol injected to lives metastatic,8 cases chemotherapy via portal vein synchronously,8 cases intercurrent X-ray,12 cases abandon treatment.Conclusions:Colorectal carcinoma with hepatic metastasis is very difficult to diagnosis before operation,ultrasound and accuracy found on operation were the secure methods for diagnosis of colorectal carcinoma with hepatic metastasis.Hepatectoming is the first way for treating colorectal carcinoma with hepatic metastasis,others way are ethanol inject,chemotherapy via portal vein synchronously,interventional radiotogy,et al.
Résumé
Objective In order to solve the scaffold material and the cell source of the tissue engineering bile duct.This experiment was divided into two parts: ⑴To cultivate the vascular smooth muscle cell(VSMCs)in vitro and observe the cultivate status of the VSMCs in 3D environment of polylatic acid-polynlycolic acid(PLGA).⑵To explore the feasibility of differentiation of rat bone marrow stromal cells towards liver stem cells in vitro.Method ⑴To cultivate the VSMCs with PLGA(the film material with 3D material) after they were successfully cultivated,and to observe the cell growth status by inverted microscope,scanning electron microscope and MTT.⑵To culture rBMSCs in vitro by culturing the full bone marrow stem cells in a system containing hepatocte growth factor(HGF).The morphology of the cells was observed by inverted microscope,and the expressions of albumin,AFP were detected with ELISA and immunohistochemistry technique.Result ⑴The VSMCs growth is prosperous in vitro with good compatibility with PLGA.⑵After being cultured with HGF,the rBMSCs showed multilateral and ovary tansformation.The differentiated cells expressed albumin and AFP.Conclusion ⑴The VSMCs were successfully cultivated and purified in vitro and have good compatibility with PLGA.⑵ The rBMSCs have the ability to-differentiate into liver stem cells in vitro.The current studies provide the experimental basis for rBMSCs to differentiate into endothelial cells of the bile duct.
Résumé
Objective: TO verify through animal experiment the validity of chemical cholecystectomy . Methods: The experimental objects seven healthy juvenile pigs,hardener was infused into the gallbladder,after infusion the samples were collected by pathoiogical examination , according to the different duration under anesthestize. Reslts:The mucous destructive and digestive process remained with one week, the inflammatory reacton in two weeks,the chronic inflatoy reaction compained a a great deal of granu lation tissue and scar formation occurred in 4th-8th week,10 weeks latter,the inflmmatory reaction reduced ,and scar tissue formed. Conclusion: Chemical cholecystectomy is safe and reliable in clinical.
