ABSTRACT
Objective To investigate the effect of magnifying endoscopy with narrow-band imaging (ME-NBI) in diagnosis of early gastric neoplastic lesion. Methods 151 patients with suspected gastric cancer underwent endoscopic examination in digestive endoscopy center from January 2013 to June 2016 were enrolled the study. They firstly received conventional white light endoscopy (WLE), then ME-NBI (including intervening part) and targeted biopsy. And all patients were divided into early cancer group (high grade intraepithelial neoplasia, intramucosal carcinoma and submucosal carcinoma, n = 72) and non-early cancer group (low grade intraepithelial neoplasia, n = 79). The area under receiver-operating characteristic curve (AUC) was performed to evaluate prognostic value of each index in early cancer. Results The incidences of the demarcation line, irregular microvascular pattern, irregular microsurface pattern and increasing intervening part in early cancer group were significantly higher than that in the non-early cancer group (P < 0.05). The AUC of ME-NBI for early gastric cancer was 0.947 and higher than 0.832 of WLE. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden index were 97.2%, 84.8%, 85.4%, 97.1% and 0.820, respectively. The AUC of intervening part for early gastric cancer was 0.907 and higher than 0.889 of the traditional VS classification, and AUC, sensitivity, specificity, PPV, NPV and Youden index of VS type combined with intervening part were 0.933, 95.8%, 83.5%, 84.1%, 95.7% and 0.794, respectively. Conclusions ME-NBI is an important method for diagnosis of early gastric cancer, and intervening part has the advantages of strong objectivity, simple and easy to operate, good repeatability, and it could be used to assist traditional VS classification in judging the nature of lesions.
ABSTRACT
Objective To investigate the effect of meridian exercises on blood glucose and clinical symptoms of community elderly type 2 diabetic patients.Methods Sixty elderly patients with type 2diabetes mellitus (T2DM) were selected from two communities from February to September in 2012.Thirty participants from one community received meridian excise-based group sport management (experiment group),the other 30 subjects from another community got meridian excise-based individual sport management (control group).Before and after the intervention,blood glucose and self-report symptoms were assessed.Results At baseline and after the intervention,there was statistically significant difference of postprandial blood glucose and self-symptom score between the two groups (t values were-5.954,-2.900,-4.214 and-3.798,respectively; all P＜0.05).After the intervention,experiment group showed statistically significant difference in self-assessment of symptom score from the control group (t=-5.484,P＜0.05).Conclusion Meridian exercises can efficiently improve diabetic patients' postprandial blood glucose and clinical symptons.
ABSTRACT
Objective To investigate the correlation rs2272087 polymorphism of STATS gene and asthma.Methods The polymerase chain reaction PCR- SBT technique was used to determine rs2272087 polymorphism in asthma and control group.Results The genotype of AA,AG and GG of rs2272087 were 0.600,0.412 and 0.167 in asthma group,and 0.430,0.200,0.367 in control group,respectively.The frequency of allele A and G was 0.903 and 0.344 in asthma group,and 0.656,0.970 in control group,respectively.There was significant difference in two groups(x2 =9.40,P ＜0.01 ;x2 =11.58,P ＜0.01 ).Conclusions The rs2272087 polymorphism of STAT5 gene may be an important candidate gene for asthma.
ABSTRACT
Objective To study the significance of the prognosis assessment by acute physiology and chronic health evaluation (APACHE Ⅱ ),sequential organ failure assessment (SOFA) score,clinical pulmonary infection score(CPIS) and multiple organ dysfunction syndrome (MODS) score in the patients of ventilator-associated pneumonia (VAP). Methods The clinical data of 68 cases with VAP in the ICU or RICU were studied. APACHE Ⅱ , SOFA and MODS scores on admission and APACHE Ⅱ , SOFA, CPIS and MODS scores on the first 24-hour of VAP diagnosis were recorded. The area under the receiver operating characteristic curve(AUROC ) and Logistic regression were used to estimate the prognostic ability by the four kinds of scoring systems. Results The APACHE Ⅱ , CPIS, MODS and SOFA scores on the first 24-hour of VAP diagnosis were significantly higher in non-survivors than those in survivors. AUROC of APACHE Ⅱ ,SOFA,MODS and CPIS respectively were 0.80,0.75,0.73,0.71. Logistic regression analysis showed that only APACHE Ⅱ＞ 18 scores on the first 24-hour of VAP diagnosis was an independent predictor of the mortality (OR: 5.7,95% CI: 1.9 - 20.0, P = 0.013). Conclusion The APACHE Ⅱ on the first 24-hour of VAP diagnosis may be a useful index in predicting progress of patients with VAP.
