Objective To observe the curative effect of cervical traction combined with low-cycle or intermediate frequency electrical current in cervical vertebrae.Methods 171 patients with cervical vertebrae were randomly divided into the therapy group and control group,86 cases in therapy group were performed the curative measure of cervical traction and low-cycle,85 cases in control group underwent the curative measure of cervical traction and intermediate frequency electrical current.Both of the two groups carried out continuous therapy for 10 days.Results There was significant difference before and after treatment within each group in CASCS score(P ＜ 0.01)and there was also significant difference after treatment between the two groups(P ＜ 0.05),the effective rate of therapy groupwas significant higher than that of control group(P ＜ 0.05).Conclusion The methods of cervical traction and low cycle or intermediate frequency electrical current has better curative effect in cervical vertebrae and cervical traction and low-cycle do much benefit in cervical vertebrae treatment.

Objective To observe and analyse the efficacy of retrograde gonarthritis with interference current and drug-iontophoresis direct current. Methods 185 patients with retrograde gonarthritis were randomly divided into treatment group 92 cases and control group 93 cases. The patients in treatment group underwent interference current and drug-iontophoresis direct current and patients in control group performed modulated medium frequency drug-ionto-phoresis direct current for two treatment courses. Results The comprehensive score of various kind of symptom such as pain、swelling、flexion、walking ability, up-down stair ability in treatment group significantly improved than that of control group (P < 0.01). Conclusion The interference current and drug-iontophoresis direct current is one of effec-tive and safe measurement in treating arthritis with main manifestation of pain and soft tissue disease.

Objective To study the expression of Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma and papillary thyroid hyperplasia and to find the differential diagnostic makers. Methods A total of 200 cases, including 100 with papillary thyroid carcinoma and 100 papillary thyroid hyperplasia by Immunohistochemistry. Results The positive rates for Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma were 100 %, 97 % and 93 %, which were significantly higher than those in the papillary thyroid hyperplasia (13 %, 31 %, 1 %) (P

Objective To provide objective parameters for differentiating pancreatic cystic tumors via using computed tomography texture analysis (CTTA) to quantify the special imaging features of pancreatic cystadenomas.Methods Enhanced CT images of pancreas from patients who were admitted in Department of Radiology in First Hospital affiliated with Zhejiang University and First People's Hospital of Hangzhou City and pathologically diagnosed as pancreatic serous cystadenomas (n =48) and mucinous cystadenomas (n =34) from January 2009 to December 2016 were retrospectively analyzed.Regions of interest were drawn on the parenchymal phase CT images in 5 slices according to the border of the tumors.Mean grey level intensity (M),variance (V),entropy (E),skewness (Ske) and kurtosis (Kur) were obtained from fine texture (σ =1.0) to coarse texture (σ =2.5).Receiver operating characteristic (ROC) curve for texture parameters with statistically difference was drawn,and the area under curve (AUC),diagnostic sensitivity and specificity were calculated.The diagnostic accuracy of senior and junior doctors was compared with the traditional CT analysis method.Results Reliability coefficient of the two radiologists was 0.809 ～ 0.997 with high consistency.Compared with mucinous cystic tumors,serous cystadenomas had a significantly different V (5.93 ± 9.02 vs 1.29±0.62),E (2.39±0.61 vs2.02±0.39) and Kur(30.18 ±42.55 vs 8.80-±4.34) in Ske0 of 2.5 (P ＜0.05),and there were no statistically significant differences on other parameters.The AUC of differential parameters for diagnosing two kinds of cystic tumors ranged from 0.56 to 0.84.The diagnostic accuracy of the traditional CT analysis method by junior doctor and senior radiologist was 60％ and 71％,respectively.Conclusions CTTA can not only effectively quantify the heterogeneity of pancreatic cystadenomas,but also is effective in the differentiation.
