Vascular endothelial growth factor (VEGF)-specific effects on vascular endothelial cells,by promoting endothelial cell proliferation,increased vascular permeability,to induce tumor angiogenesis and lymphangiogenesis in tumor development has played key role.Studies have shown,VEGF and its receptor expression and the incidence of thyroid cancer,lymph node metastasis,prognosis,inhibition of VEGF and its receptor expression in anaplastic thyroid cancer and medullary cancer treatment in a certain application.

Cataract surgery is not only a surgery for vision resuming, but also a kind of refractive surgery. Besides improving the design of intraocular lens, perfecting the technique of surgery and examining far and near visual acuity, we should stress the objective evaluation including contrast sensitivity, glare sensitivity, accommodate ability, binocular function and wavefront aberation for better visual results.

Objective To investigate the role of individualized psychological intervention in gastroscopy.Methods 286 patients first underwent gastroscopy were randomly divided into the intervention and control groups,143 patients in each group. Individualized psychological intervention were provided for intervention group,and the patients of control group were just given routine nursing care. All the patients were measured by self rating anxiety scale (SAS) ,which were as measuring standards before and after intervention. At the same time,the blood pressure and heart rate were compared before and after intervention. Visual analogue scale (VAS) was observed to investigate the satisfaction of patients after operation. Results Compared with control group,anxiety rate and degree,blood pressure and heart rate in intervention group were lower( P ＜ 0. 05 ). The test of VAS revealed that the satisfaction of patients in intervention group was significantly higher than that in control group ( P ＜ 0. 05). Conclusion Individualized psychological intervention could improve negative emotion and relieve anxiety and affliction of patients underwent gastroscopy, and the satisfaction degree for gastroscopy was improved.

0.05).Conclusion At 4℃ storage time up to 2 weeks showed no significant influence on the contents of HbA2 detected by electrophoresis.

Purpose:To study the expression of Epstein-Barr virus gene BARF1 in nasopharyngeal carc inoma cells, to uncover the mechanism and effects of Epstein-Barr virus in the pathogenesis of EBV related carcinomas, and to offer some experimental supports for the prevention and treatment of EBV related carcinomas Methods :After RNA extraction from nasopharyngeal carcinoma samples, RT-PCR was con ducted to amplify the EBV gene EB virus associated nuclear antigen-1 (EBNA1) an d the new gene Bam HI A open reading frame 1 (BARF1) Then the PCR products wer e electrophoresed by 2% agarose gel and the product bands were detected and phot ographed Results:Of the 13 samples, 11 were qualified for the RNA qualit y And all of the 11 NPC cases were EBNA1 positive, showing the EB virus infect ion in the carcinoma cells 9 of the 11 cases were BARF1 positive, the positive rate was nearly 82% Conclusions:The EB virus gene BARF1 was highly expressed in the NPC samples This implies t hat apart from the latent membrane protein 1 (LMP1), BARF1 may play an important role in the pathogenesis of NPC The exact mechanisms of the BARF1 effects on the pathogenesis of NPC need to be studied further

Objective:To investigate the value of the Holter monitoring in silent myocardial ischemia (SMI).Methods: Sixty-eight patients with silent myocardial ischemia had the Holter monitoring.Results:Sixty-eight cases were detected 263 times of the SMI, Among them 05:00-12:00 highest incidence occurs 156 times total, 52.88% of the total number; second highest incidence of the time period of 18:00-22:00, total occurred 97 times, the total number of of 32.88%; 22:00-05:00 totaling occurred 46 times, the total number of 15.59%. There are a total of 187 predisposing factors array times, 63.34% of the total number. Heart rate greater than 100 bpm, SMI total array occurred 175 times, 59.32% of the total number; heart rate>65 bpm and

Objective To investigate the expression of Hedgehog signaling pathway members,Shh,Gli1,Sufu and TAK1 as well as phosphorylation-TAK1 (p-TAK1) protein in human pancreatic carcinoma tissues and to explore its relationship between the expression of proteins and the clinicopathologic parameters.Methods The expressions of Shh,Glil,Sufu,TAK1,p-TAK1 proteins in 38 samples of pancreatic cancer tissues and pairing adjacent normal pancreatic tissues were detected by immunohistochemical method.The relationship among the proteins and the relationship between the expression of the proteins and the clinicopathologic parameters were examined.Results The positive expression rates of Shh,Glil,Sufu,TAK1,p-TAK1 protein in human pancreatic carcinoma were 86.8％ (33/38),52.6％ (22/38),68.4％(26/38),55.3％ (21/38),52.6％ (20/38),but they were not expressed in adjacent normal pancreatic tissues.Gli1 expression was positively related to distant metastasis and clinical staging (r =0.524,0.361,P ＜0.05),Sufu expression was positively related to patient's gender (r =-0.378,P ＜0.05),TAK1 expression was positively related to clinical staging (r =0.468,P ＜ 0.05),p-TAK1 expression was positively related to clinical staging and distant metastasis (r =0.418,0.361,P ＜ 0.05).Gli1 expression was positively related to TAK1 and p-TAK1 expression in pancreatic cancer tissues (P ＜ 0.05).Conclusions Hedgehog signaling pathway and p-TAK1 may play a role in the pathogenesis of pancreatic cancer,and the two pathways may interact with each other.

Objective To investigate the predialysis education on dialysis timing of patients with end-stage renal disease (ESRD). Methods 129 patients with chronic renal failure (CRF) and serum creatinine(Scr)＞442μmol/L, endogenous creatinine clearance rate (Ccr)＜20 ml/min were randomly divided into the experimental group(70 cases) and the control group(59 cases), the experimental group received predialysis education, the control group received routine care.The basic situation, dialysis timing, depression and quality of life on the 6th,12th months after dialysis were assessed. Results There was no significant difference in age, sex, education background, health care payment manners, employment, serum creatinine, endogenous creatinine clearance rate before education.For the timing of dialysis, Ccr for the experimental group was (9.49 ± 0.77)ml/min, Ccr for the control group was (4.54 ±1.79) ml/min,the difference was significant, depression and quality of life between two groups after 6,12 months of dialysis was also statistically different. Conclusions Strengthening predialysis education is conducive to a timely start of dialysis and can effectively improve the quality of life in patients with ESRD.

ObjectiveTo analyze the CT appearances of primary pulmonary non-Hodgkin lymphoma(PPNHL)in order to improve its diagnosis.MethodsCT manifestations of 19 cases with PPNHL confirmed by pathology and clinical follow-up were retrospectively analyzed.ResuitsNodules 7 cases and masses 8 cases in PPNHL were ill-defined and markedly enhanced,in which air bronchogram was commonly seen.Muhiple patchy areas distributed in the bilateral lungs were found in 9 cases.Consolidation 7 cases was lobar and markedly enhanced,in which air bronchogram was commonly seen.Interstitial change manifested as bilateral diffuse ground-glass opacities and reticular shadow was found in 1 case.Mixed imaging manifestations were detected in 10 cases.Pleural effusion 4 cases was uncommon.Conclusion CT manifestations of PPNHL are varied,but some specific imaging features still exist,CT examination combined with clinical manifestations is helpful for the diagnosis of PPNHL.
