Objective To study the diagnostic value of 3 dimentional CT reconstruction in upper urinary tract obstructive diseases. Methods 37 patients with upper urinary tract obstructive diseases underwent thin slice helical CT scan and 3 dimentional reconstruction of the urinary tract as well as 3 dimentional CT angiography when needed. Results All the cases have been definitely diagnosed including ureteral carcinoma in 8, bladder carcinoma in 2, ureteral calculi in 9, benign ureteral stricture in 7, congenital malformation in 7 and pelvic tumor in 4.All the patients except those with pelvic tumors underwent surgical intervention and the diagnosis were confirmed.The operative findings were in concord with the helical CT results. Conclusions 3 dimentional CT reconstruction of the urinary tract can provide distinct urinary tract images and helps determining the site and the cause of the obstruction. Compared with other methods, the procedure has the advantages of high resolution, rapid imaging and low invasiveness. It might become the most valuable means of detecting upper urinary tract diseases.

0.05). No significant differences were detected in the median time of remission, median survival time and 1-, 2-year survival rates between the groups. Moreover, no significant differences were detected in the grade Ⅲ～Ⅳ leukopenia, grade Ⅲ～Ⅳ thrombocytopenia, grade Ⅲ～Ⅳ nausea and vomiting and grade Ⅲ～Ⅳ constipation between the groups. Conclusions:The response rate of the MVP regimen is slightly lower than the HMVP regimen, but the HMVP regimen is not noticeably superior. It may increase the toxicity such as leukopenia, nausea/vomiting and constipation, as wellas being more expensive. In short, MVP regimen should be selected between the regimens in the chemotherapy of advanced NSCLC.

Objective To analyse protein tyrosine phosphatase 1B (PTP1B) gene mutation in myeloproliferative neoplasms (MPN).Methods DNA sequencing technology was used to detect DNA sequences of PTP1B in MPN patients (n =84) and normal controls (n =37).Results For Exon1-6,Exon9 and Exon10,84 cases of MPN patients and 37 cases of control group were not detected mutation.For EXON 8,18 of 84 MPN patients had Exon8 C/T heterozygous mutation and 10 of 37 normal controls were detected C/T heterozygous mutation.There was no significant difference between MPN patients and normal controls (x2 =0.453,P =0.501).Exon7 was detected in 38 MPN patients and 2 cases of patients were found C/T heterozygous mutation,while in the control group,1 case with G/C heterozygous mutation.All of the cases were not detected homozygous mutation.Conclusion Using DNA sequencing technology to detect gene mutations of PTP1B,there is no significant difference between MPN patients and normal controls.

Objective To investigate clinical effect of sEMG-BFB training combined with swallowing training for dysphagic patients with cerebral infarction,to provide a reference for life quality improvement of dysphagic patients.Methods 48 patients with cerebral infarction combined swallowing disorder were selected.According to the digital table,patients were divided into the control group and observation group,24 cases in each group.Patients in the control group were given training such as routine training and behavioral swallowing training,while patients in the observation group were given sEMG-BFB training based on training of the control group.FOIS score,Kubota's water drinking test grade,SSA score and SWAL-QOL score were compared between two groups.Results After treatment,FOIS score,SSA score and SWAL-QOL score of the observation group were (3.82 ± 1.04),(19.97 ± 8.17),(158.23 ± 10.27),which were significantly higher than those of the control group [(2.82 ± 1.21),(24.21 ± 6.31),(139.23±7.32),t =4.394,4.115,5.642,all P ＜ 0.05] ; Kubota's water drinking test grade of the observation group was better than the control group,the difference was statistically significant (U =283.43,P ＜ 0.05).Conclusion sEMG-BFB training combined with swallowing training is helpful for dysphagic patients with cerebral infarction to improve swallowing ability and life quality.

Objective To identify etiological factors for non-ulcer dyspepsia (NUD) in elderly patients presenting to the emergency department.Methods A total of 97 elderly patients with NUD presenting to the emergency department from January 2011 to December 2013 were enrolled in the NUD group and 116 elderly people undergoing annual physical examinations served as the control group.Clinical data,including Helicobacter pylori (HP) infection,unhealthy living habits,anxiety,depression and regular intake,were collected and compared between the two groups.Results Compared with the control group,the NUP group showed a higher HP infection rate [70.1％ (68/97)vs.54.3％ (63/116),x2 =5.565,P＜0.05],a higher incidence of unhealthy living habits (unhealthy dietary habits,smoking,drinking,and lack of regular exercise) (P＜0.05),a higher incidence of suspect anxiety/anxiety and a higher incidence of regular intake [30.9％ (30/97) vs 10.3％ (12/116),x2=14.138,P＜0.05].SerumpepsinogenⅠ(PGⅠ) [(178.7±13.6) μg/L vs.(125.2±10.5)μg/L,t=1.971,P＜0.01] and serum pepsinogen Ⅱ(PG Ⅱ) [(28.8±5.3) μg/L vs.(14.7±3.8)μg/L,t=1.960,P＜0.01] levels were also higher in the elderly NUD patients than in the control group.Conclusions HP infection,unhealthy living habits,anxiety and/or depression,and regular intake are closely associated with NUD in the elderly.Serum PGⅠ and PGⅡ could be used as markers in screening for malignant lesions in elderly patients with dyspepsia.
