Objective To explore the effect of earplugs on the reduction of noises in the wards with a few patients after gynecological surgery.Methods Two hundred and fifty-four patients hospitalized in our hospital after gynecological surgery from March 2012 to May 2013 were divided into control group(n=124)and observation group(n=130). The observation group was managed with earplugs and the control group patients received routine nursing. The two groups were compared in terms of breathing,heart rate,blood pressure,24 h scores on anxiety before and after operation.Results The postoperative respiration,heart rate,blood pressure of the observation group patients was significantly lower than those of control group(all P<0.05),anxiety score was significantly lower than that of the control group(P<0.01). Conclusions Earplugs can create a quiet environment in wards with a few patients after gynecological surgery and help to stabilize vital signs and reduce anxiety.

Objective To evaluate left ventricular function in patients with acute myocardial infarction and to investigate the clinical value by two-dimensional strain imaging of ultrasound.Methods Study population was consisted of 28 patients with acute myocardial infarction of wall anterior and 30 healthy subjects.Images were recorded from the left ventricular the apical 4-chamber view,apical 3-chamber view,apical 2-chamber view respectively.Two-dimensional strain and strain rate were measured in the left ventricular segments using two-dimensional strain software.We analyzed that relationship between two-dimensional the global peak systolic strain,global strain rate and left ventricular end systolic volume(LVESV),left ventricular end diastolic volume(LVEDV),wall motion score index(WMSI),left ventricular ejection fraction(LVEF).Results ①Infarct segments in myocardial infarction group showed significant reduction of peak systolic strain as compared with normal group(P

Background and purpose:Glioblastoma is one of the most common intracranial tumors, the morbidity and mortality are both high, and the molecular biological mechanism of the disease is still unclear. In this study, we detected the gene expression of tyrosine kinase receptor (TKR) pathway in primary glioblastoma(GBM) with low-density array, furthermore we analyzed the significance of the gene expression change. Methods:We detected 26 genes of RTK pathway in 10 primary GBM tissues and 9 normal brain tissues (gained from the decompression operation of brain trauma), and analyzed the different expressions of these two kinds of tissues by statistic method.Results:The Ct values of MAP2K1 and MAP2K4 in normal brain tissues were 1.6?1.7 and 2.2?2.1, the Ct values of MAP2K1 and MAP2K4 in primary GBM tissues were 3.9?1.5 and 5.0?2.0, and the Ct different values between normal brain tissues and primary GBM tissues of both genes were -2.3 and -2.8(P

Objective To detect CT appearances of different stomach diseases and evaluate the value of CT in the diagnosis of gastric diseases.Methods 62 cases of stomach diseases were detected by CT.Results 49 cases of gastric cancer,7 cases of stomach leiomyoma,3 cases of stomach ulcer,1 cases pylorus fleshy were examined,2 cases of stomach epineurial tumor.There was 91% correspondent rate of CT with pathologic examination.Conclusion CT imaging analysis is not only important to determine to gastric cancer,but also is great valuable to diagnose and differentiate the different stomach diseases.

University of Manchester who first introduced Problem based learning(PBL)to the UK medical education,and adopted this new curriculum in 1994.Notably,Cambridge and Oxford have always had a high proportion of student-centred and self-directed learning,and have therefore not introduced PBL.Other medical schools have followed the example of Manchester,now PBL has become the mainstream curriculum in British medical edacation.First,this article is going to introduce how PBL curriculum is structured at Manchester medical school,and then reflect and give some thoughts on its current practice.

Objective To evaluate the microscopic characteristics of hepatocellular carcinoma (HCC) invasion,and to provide the reference for GTV-to-CTV expansion. Methods From January 2002 to January 2006,149 HCC patients treated by surgical resection were included. The pathologic slices and clinical data were reviewed, including the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage, histology grade, serum alpha-fetoprotein (AFP), platelet count and the degree of liver cirrhosis. The distance between the tumor capsule and the invasion was measured by 2 senior pathologists. Results of the 149 patients evaluated,79(53.0%) patients presented micro-invasion ranged between 0.5-4.0 mm. The recurrence rate was higher in patients with micro-invasion than those without (44% vs 29%, P=0.047). The invasion extent was positively relative to the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage,histology grade and AFP,while negatively relative to the platelet count. A score system was established according to five predictors of tumor size, capsule status, portal vein invasion, AFP and platelet count. The invasion distance below 2 mm was in 96.6% patients who had≤2 points and only 83.3% for those with 2 points. Conclusions For HCC patients,the invasion extent is relative to the tumor size,cap sule status,portal vein invasion, AFP and platelet count. These 5 predictors could be potentially used as a score system for GTV-to-CTV expansion.

Sufficient embryos are needed for the preservation of Beagle dogs germplasm resources and the prepara-tion of gene?modified human disease animal models. Up to now, the induced ovulation technique has no effect on dogs,it is hard to obtain mature oocytes in vivo, although the scientists try a lot in many aspects, but still could not make a break?through. The in vitro maturation rate is too low to support the preservation of germplasm resources, application in gene?modified disease models and biomedical research. Aiming to provide useful information on breakthrough in dog oocytes mat?uration, this review will summarize the effect of different age and reproductive stage,different morphology and size of the oo?cytes and lipid droplet on the in vitro maturation of dog oocytes.

Objective:To investigate the etiololgy and pathogenesis of cholesterol granuloma of the marillary sinus. Method:Five patients with cholesterol granuloma of the maxillary sinus were analysed retrospectively. Result: The cholesterol granuloma was a particular form of tissue reactions of granulation. The clinical symptoms of the disease was short of specificity. Conclusion; The pathogenesis of cholesterol granuloma includes hyperlipemia, obstruction of airfilled cavity ventilation and impaired drainage. The final diagnosis was based on pathologic examination. The treatment should begin with the intervention and treatment of hyperilpemia. Radical cure can be a-chieved by operation.

To determine the effects of Von Hippel-Lindau (VHL) on the invasion and migration of glioma U251 cells. Methods:U251 GBM cells were transfected using VHL expression plasmid. Real-time polymerase chain reaction was conducted to de-tect VHL mRNA expression after transfection. Western blot assay was used to measure protein (VHL, MMP-2, and MMP-9) expres-sion. Tumor invasion and migration were examined by the Transwell and wound-healing experimental methods after VHL up-regula-tion. The intracranial model of nude mouse was developed using U251 cells transfected by VHL expression plasmid, and immunohisto-chemical staining was used to measure protein (VHL, MMP-2, and MMP-9) expression in the tissue sections. Results: In the U251 cells transfected by VHL expression plasmid, the expression of VHL mRNA and VHL proteins increased, and the expression of MMP-2 and MMP-9 protein decreased. Meanwhile, the invasion and migration of glioma U251 cells were also inhibited. Immunohistochemical staining results showed that the expression of MMP-2 and MMP-9 proteins decreased, and the VHL protein expression increased after transfection. Conclusion:VHL can inhibit the invasion and migration of glioma U251 cells. Thus, VHL gene can be used as a target for the gene therapy of gliomas.

Objective To study the clincial effectiveness and safety of endoscopic sphincteropapillotomy combined with balloon dilation for decompensated cirrhosis accompanied with choledocholithiasis.Methods Data of 79 cases of decompensated cirrhosis patients with choledocholithiasis who underwent limited endoscopic sphincterotomy plus endoscopic papillary balloon dilation (ESBD,the ESBD group) and 42 cases who underwent endoscopic papillary balloon dilation(EPBD,the EPBD group)were retrospectively analysed and compared for complete stone clearance rate,one-time stone clearance rate and complications.Results The rate of complete stone clearance and one-time stone clearance were 94.9％ (75/79) and 77.2％ (61/79)in ESBD group,and those were 88.1％ (37/42) and 59.5％ (25/42) in EPBD group respectively.The rate of complete stone clearance was a little higher in ESBD group than that in EPBD group.In ESBD group,ERCP-related bleeding occurred in 3 patients (3.8％),post-ERCP hyperamylasemia in 3 (3.8％)and post-ERCP pancreatitis in 2 (2.5％) ; while in EPBD group,post-ERCP hyperamylasemia occurred in 8 patients(19.0％),post-ERCP pancreatitis in 6(14.3％) and ERCP-related bleeding did not occur.There were no significant difference in ERCP-related bleeding between ESBD group and EPBD group (P =0.551).However,the rates of post-ERCP pancreatitis and hyperamylasemia in ESBD group were significantly lower than those in EPBD group(P ＜ 0.05).Conclusion ESBD is a safe and effective procedure for choledocholithiasis accompanied by decompensated cirrhosis,with several advantages over EPBD in terms of higher one-time stone clearance rate,reduced risk of post-ERCP pancreatitis and hyperamylasemia,and without noticeable increase in the risk of bleeding related to ERCP.
