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.

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

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

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

Objective To evaluate the efficacy of different duration of low-carbohydrate diet (LCD) intervention on glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) patients. Methods Randomized controlled trials (RCTs) of LCD intervention in T2DM patients were collected in the databases such as MEDLINE, PubMed, OVID, China National Knowledge Infrastructure, China Scientific Journal Database by VIP, Wanfang database, et al.Data were analyzed by RevMan 5.3 version. Results Eight RCTs were included. The results of Meta-analysis indicated that the effects of lowering HbA1c by LCD intervention for three (Z=2.28, P<0.05) and six months (Z=14.99, P<0.01) were better than other diabetes diets, but there was no significant statistical difference between one (Z=0.65, P=0.51) and two years (Z=1.62, P=0.10). Conclusions Hypoglycemic effect of short-term LCD was better than other diabetes diets, but long-term effect was similar between them. LCD was a therapeutic diet suitable for T2DM patients.

AIM:To explore the effect of Pycnogenol on transforming growth factor-β1 ( TGF-β1)-induced he-patic stellate cell activation .METHODS:Cultured LX-2 cells were treated with 5μg/L TGF-β1 and different concentra-tions (0, 10, 25 and 50 mg/L) of Pycnogenol.The viability of the LX-2 cells under the conditions with or without autoph-agy inhibitor 3-MA and ERK inhibitor PD98059 was determined by MTT assay .The protein levels of α-SMA, ColⅠ, TIMP-1, LC3-Ⅱ/Ⅰ, beclin 1, p-ERK1/2 and ERK1/2 were detected by Western blot .RESULTS:Compared with con-trol group, 5μg/L TGF-β1 treatment elevated the cell viability , and increased the protein levels of α-SMA, ColⅠ, TIMP-1, LC3-Ⅱ/Ⅰ, beclin 1, p-ERK1/2, and ERK1/2 in the LX-2 cells (P<0.05).However, these effects were reversed by Pycnogenol pretreatment in a dose-dependent manner and the inhibitory effect of 50 mg/L Pycnogenol was the most sig-nificant in the LX-2 cells (P<0.05).Furthermore, compared with TGF-β1 group, pretreatment with 50 mg/L Pycnog-enol, 5 mmol/L 3-MA or 20 μmol/L PD98059 downregulated TGF-β1-induced cell viability and the protein levels of α-SMA and LC3-Ⅱ/Ⅰ in the LX-2 cells ( P<0.05 ) .CONCLUSION: Pycnogenol suppresses TGF-β1-induced hepatic stellate cell activation via p-ERK and autophagy inhibition .

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.
