Objective To study the effect of regional arterial chemotherapy (RACT) on unresectable gastric carcinoma (URGC). Methods The clinical data of 100 patients with URGC treated by RACT were retrospectively analysed. Results In addition to different degree of symptoms improvement, the size of gastric cancer became smaller in 81 2% of the cases, and the survival time of patients had been prolonged (mean 29 5 months). Conclusions RACT is more effective for treating URGC and worthly of further clinical study.

Background The ubiquitin-proteasome pathway(UPP)involves 80%-90% degradation of all in- tracellular proteins.Both ubiquitin and rat component 3 of proteasome(RC3)are hence considered to be central me- diators for cell biology.Objective To evaluate the effect of simvastatin on neointimal hyperplasia and the expres- sion of ubiquitin and rat component 3 of proteasome(RC3)after balloon injury in carotid artery.Methods Thirty- two male SD rats were randomly to receive,low dose(0.4 mg/ng,n=8),or moderate(4 mg/ng,n=8),or high- dose(40 mg/ng,n=8)of simvastatin treatment for 28 days.Common carotid aortic artery was injuried rat ballon. The ratio of intima-media(I/M)thickness was determined.The expression level of ubiquitin and RC3 mRNA were assessed by RT-PCR.The expression level of ubiquitin protein was examined with immunohistochemistry. Results Simvastatin inhibited the expression of ubiquitin and RC3 mRNA and ubiquitin protein in dose dependent manner.The intima-media ratio(-50.2 %)and the expression of ubiquitin(-60.3 %)and RC3 mRNA and ubiq- uitin protein(-60.5 %)was reduced by the high dose simvastatin [40 mg/(kg?d)](P

Objective To discuss the application of the bolus chasing DSA technology in angiography in thoracic, abdominal, common iliac and four limbs′ arteries. Methods Bolus chasing DSA with Mask Before program of the system was performed in 40 procedures in 25 patients, using the control handle to control the moving of the bed, and obtained the real time bolus chasing DSA pictures at the blood stream speed. Results In the 40 procedures, photographing in 35 had good qualities, accounting for 87.5%, but not good in 5, accounting for 12 5%, which could still meet the request of diagnosing after non subtraction processing. Conclusion Bolus chasing DSA could display a large scale of anatomical skeleton and blood stream condition from chest to the four limbs exactly. It was a new method that could be taken to observe real time continuous multi sections of blood vessel structure.

Objective:To investigate the 256 slice spiral CT pulmonary angiography (CTPA) application value by using multiple stage double mixed injection velocity tracking method in the diagnosis of pulmonary embolism.Methods: Fifty patients with pulmonary embolism from 2014 January to 2015 January were treated in our hospital patients as the research object. Using a random number table method, all patients were randomly divided into observation group and control group, 25 cases each group of patients, two groups of patients in our hospital by imaging with 256 slice spiral CT pulmonary artery (CTPA), the control group were treated by routine pre injection time density curve method, was used in the observation group than in mixed injection agent tracking method by two physicians, CT, using the double-blind assessment of two groups of patients with image quality and quantification of pulmonary artery trunk.Results: in the control group, 25 patients were satisfied with the time - density curve, the results of 5 conventional image quality scores showed no significant difference between the two imaging methods, was not statistically significant; two groups of patients with pulmonary artery trunk, branch clear imaging score and endovascular CT value had no significant difference(t=1.892,t=1.952,t=1.832;P>0.05), but the observation group patients with CTPA were examined by contrast agent dose was significantly lower than the control group, the patient''s heart rate, blood pressure was significantly lower than the control group(t=2.315,t=1.958,t=2.982;P<0.05), with statistical significance. Conclusion: CTPA with multi period mixed double flow injection method can guarantee the tracking based on image quality and diagnostic value can effectively reduce the contrast agent dosage and application effects of cardiac function, and the examination is relatively simple, safe, has clinical value of application and popularization.

Objective:To investigate the effect and application feasibility of low tube voltage, low concentration of contrast agent volume to CTA in the diagnosis of coronary artery stenosis and its effect.Methods: Seventy two cases of suspected patients with coronary atherosclerosis selected as the object Using random number table method, all patients were divided into group A and group B 36 cases in each group, two groups of patients underwent 320 slice CTA examination, in group A the tube voltage is 120kV, the contrast agent was 350mgI/mL iodixanol group, B tube voltage is set to 100kV, the contrast agent was 270mgI/mL iodixanol. According to the examination results of group A, group B and catheter coronary angiography (CCA), evaluated group A, group B of acquiring the image quality and radiation dose of patients, and analyzed the sensitivity of A, B and CCA examination of the extent of coronary artery stenosis degree and deliberately.Results: The quartering method showed no significant difference between the group A and the group B of image quality. There was significant difference between the two groups of patients with the image noise and enhance the effect (t=-4.736, 11.927;P<0.05); Group B of coronary artery stenoses (more than 50%) and severe stenosis (more than 75%) sensitivity, specially degree and coincidence rate compared with the results of CCA showed no significant difference. Kappa consistency analysis showed that the two consistency is good(kappa=1.320,P<0.001).Conclusion: In the premise of ensuring the image quality with low tube voltage, low concentration of contrast agent volume coronary CTA examination had safety and reliability of inspection.

ObjectiveTo explore the etiology of incisional hernia of abdomianal wall.Methods98 cases with incisional hernia were analyzed retrospectively in terms of incision type, technique of suture, suture materials,infection of incision, and the time of occurrence.ResultsLongitudinal incision, improper technique of suture,infection, increase of intraabdominal pressure, and diabetes mellitus were risk factors of incisional hernia. ConclusionsTransverse incision, prevention of infection of the incision, strict aseptic manipulation and hemostasis were effective in the prevention of incisional hernia. Most hernia developed within 6 months postoperatively.

Proliferation and migration of vascular smooth muscle cells (VSMC) are common pathological features of diabetic vascular complications,such as atherosclerosis and hypertension. Phenotypic modulation of VSMC is the basis for VSMC proliferation and migration. Therefore, studies on VSMC phenotypic modulation and its mechanisms in diabetes mellitus were of important significance to the prevention and therapy of diabetic vascular complications. This paper introduces VSMC phenotypic modulation and the underlying mechanisms in diabetes mellitus, and summarizes advance of studies on traditional Chinese medicine intervention upon VSMC phenotypic modulation, so as to provide reference for preventing and treating diabetic vascular complications with traditional Chinese medicines.

The hospital information structure, which is made up of various medical business systems, is suffering from the problems of the "information isolated island". Medical business systems in the hospital are mutually isomerous and difficult to become a whole. How to realize the internal barrier-free interaction of the patients effective medical information in the hospital and further to complete the area sharing of patients longitudinal diagnosis and treatment information has become a question having to be solved urgently in the process of healthcare informatization. Based on the HL7 standard, this paper refers to the IHE technical framework, expounds the overall structure of the interaction in the hospital internal and area sharing of medical information with the medical information exchange platform. The paper also gives the details of the whole process of the complete display of the discrete patient health information using Portal technology, which is saved in the business systems in different hospitals. It interacts internally through the information exchange platform and at last stores the information in the regional clinical data repository (CDR).
