Objective To explore the clinical significance of combined detection of carbohydrate antigen(CA)125,CA153,carcinoembryonic antigen(CEA) and tumor specific growth factor(TSGF) in diagnosis for breast cancer.Methods A total of 125 patients with breast cancer were recruited as objects in this study from march 2015 to march 2016,65 patients in breast cancer group,60 patients in benign breast disease group,meanwhile 55 healthy person were enrolled in the control group.Serum tumor markers such as CA125,CA153,CEA and TSGF were detected and compared in the three groups.Results The serum CA125,CA153,CEA and TSGF levels in the breast cancer group were significant higher than those of benign breast disease group and healthy group,the differences were statistical significant(P<0.05).At the same time,the sensitivity and specificity of joint detection of four kinds of serum tumor marker were 90.2% and 88.9%,which were higher than those of single serum tumor marker detection(χ2=26.12,P<0.05).Conclusion The four kinds of serum tumor markers combined testing not only increases the sensitivity of breast cancer diagnosis,but also improved the specificity of diagnosis of breast cancer.

Objective To survey on knowledge of home blood pressure monitoring (HBPM) in community physicians of Zhejiang province.Methods One hundred and thirty eight community physicians from Xiacheng District of Hangzhou Municipality were assigned in intervention group (n =70) or control group (n =68).The knowledge of home blood pressure monitoring was surveyed by using the China HBPM questionnaire in both groups.Results Total 132 valid questionnaires were returned,including 70 from intervention group and 62 from control group.The results showed that 80.0％ (61/70) physicians in intervention group and 62.9％ in control group frequently suggested hypertensive patients to have HBPM in out-patient clinics (P ＜ 0.05).Physicians who correctly instructed patients to use upper arm electronic sphygmomanometer,to measure blood pressure in morning and night,to repeat 2-3 times each time,to record result 3 times,and to take ≥ 135/85 mmHg(1 mmHg =0.133 kPa) as criteria of hypertension in intervention and control groups were 67.1％ (47/70) versus 32.3％ (20/62),5.7％ (39/70) versus 29.0％ (18/62),92.9％ (65/70)versus 66.7％ (40/62),38.6％ (27/70)versus 6.4％ (4/62)and 57.1％ (40/70) versus 38.7％ (24/62),respectively,and the differences between two groups were all statistically significant (P ＜ 0.05).As for measuring frequency,92.9％ (65/70) physicians in intervention group and 67.7％ (42/62) in control group considered that blood pressure should be measured every day for poorly controlled patients ; 81.4％ (61/70) versus 14.5 ％ (9/62) considered that blood pressure should be measured every week for well-controlled patients; 87.1％ versus 35.5％ (22/62) considered that blood pressure should be measured every year at least for people with normal blood pressure; there were significantly differences between two groups (P ＜ 0.05).The community physicians generally considered that HBPM can be used to improve the awareness of hypertension for patients and to increase the blood pressure control rate in community.

AIM: To investigate the therapeutic effects of "Shen Yan Yi Qi Solution",a chinese Medicine,on nephrotoxic serum nephritis in the rat. METHODS: Nephrotoxic serum nephritis model of the rat was set up by the Clarke's method. RESULTS: Proteinuria and renal insufficiency occurred in all rats after nephrotoxic serum (NTS) injection,but symptoms in treatment group were reduced. At 2nd week,the typical linear deposition of IgG along the glomerular basement membrane (GBM) was observed by fluorescence microscopy. Mesangial hyperplasia and crescent formation in glomeruli were also observed by light microscopy. In treatment group,all the above lesions were alleviated. CONCLUSION: It demonstrated that "Shen Yan Yi Qi Solution" might alleviate the pathological change of glomeruli and improve renal function.

Objective:To assess the predictive values of bioelectrical impedance analysis(BIA)-measured body fat indices to abnormal lipid profiles, and to preliminary propose optimal cut-off values of body fat in children and adolescents.Methods:Children and adolescents, aged 6-16 years, were selected from 30 schools (8 primary schools, 21 middle schools and one 12-year education school) in Dongcheng, Tongzhou, Fangshan and Miyun districts of Beijing by adopting a stratified cluster sampling method from November 2017 to January 2018.Questionnaire survey, body mass index(BMI), body fat mass index (FMI), fat mass percentage (FMP) and four lipid profiles were conducted.Results:A total of 14 309 participants, aged (11.0±3.3) years, were enrolled in the analysis, with 49.9% boys.In boys and girls, the percentile values ( P60- P95) fitted by FMI and FMP with K-median-coefficient of variation(LMS) method were taken as the cutting points, and P75 values were selected as the cut-off points of excessive body fat for their better sensitivity, specificity, predictive value and area under curve (AUC) for identification of abnormal lipid profiles.Boys with FMI above P75 accounted for 28% of the total population, and controlling boys with FMI below P75 could prevent dyslipidemia of 8%-57%.FMI in girl population occupied about 26% of the above, and controlling FMI in girl population below this cut-off point may prevent dyslipidemia from 8%-42%.FMP observed similar results to FMI.Assessed by FMI or FMP with P75 cut-off values, adiposity performed better than BMI for recognizing abnormal lipid profiles in boys (AUC: 52.4%-69.6% vs.50.2%-67.1%, P<0.05) rather than in girls ( P>0.05). In addition, when FMI or FMP beyond P90, the specificity of each abnormal lipid profiles was around 90%. Conclusions:The recommend cut-off points for body fat may be to assess children′s adiposity, and can be applied in preventive activities.

OBJECTIVE: To investigate the expression of SOX2 in laryngeal carcinoma and analyze the relation of SOX2 and clinical factors. METHOD: We measured the expression of SOX2 protein in 45 laryngeal carcinoma fresh samples and 45 paracarcinoma tissues (cutting margin > 0.5 cm) with flow cytometer (Epics-XL II), 20 normal laryngeal mucosa samples were also studied as controls. RESULT: The quantitative and qualitative expression of SOX2 protein in laryngeal carcinoma tissues was obviously higher than those in paracarcinoma and in normal laryngeal mucosa tissues respectively (P < 0 05). There was no significant difference between the expression of paracarcinoma and normal laryngeal mucosa tissues. In laryngeal carcinoma, the expression of SOX2 protein wasn't significantly related to patients' clinical classification, tumor size, smoking history, patients' age and sex but related to metastasis, pathological grade and clinical stage. CONCLUSION The high expression of SOX2 may contribute to the carcinogenesis and development of laryngeal carcinoma. It is an important index of judging metastasis and staging and prognosis of laryngeal carcinoma to measure the expression of SOX2 protein.

Objective To evaluate a model for axillary lymph node involvement combining CK19 mRNA with contrast enhanced ultrasound sonography (CEUS) score in operable breast cancer.Methods Operable breast cancer patients planned for sentinel lymph node (SLN) biopsy were enrolled.Preoperative CK19mRNA expressions in peripheral blood and CEUS score of axillary lymph nodes were tested before surgery.In the training set,postoperative sentinel lymph node (SLN) and non-sentinel lymph node (nSLN) pathological results were taken as the gold standard,effective modeling variables were screened,logistic regression was used to establish the prediction model.Parallel control studies were conducted between the validation set and the MSKCC model to evaluate the prediction accuracy and prediction efficiency.Results From Oct 2015 to Nov 2016,359 cases (training set) were enrolled and mathematical formulas for predicting SLN and nSLN were established,respectively.The sensitivity,specificity and AUC of predicting SLN involvement were 91.36％,94.92％ and 0.979 respectively.The sensitivity,specificity and AUC of predicting nSLN metastasis were 91.04％,90.53％ and 0.932 respectively.From Dec 2016 to Jul 2017,219 cases (verification set) were included.The sensitivity of SLN metastasis predicted by the model was 91.84％,the specificity was 96.69％,and the AUC was 0.979,significantly superior to the MSKCC model (0.739).The sensitivity,specificity and AUC of predicting nSLN metastasis were 95.35％,92.73％ and 0.945 respectively,significantly superior to the MSKCC model (0.873).Concolusions Combined with peripheral blood CK19 mRNA and CEUS score,the prediction model for axillary lymph node involvement for operable breast cancer,SLN/nSLN involvement probability can be calculated and qualitative judgment can be made.The overall accuracy and AUC of this model are better than the prediction model of MSKCC.

Objective:To seek any differential effect of combining repeated transcranial magnetic stimulation (rTMS) with a modified version of constraint-induced movement therapy (mCIMT) on the walking ability of stroke survivors.Methods:Seventy-five stroke survivors were randomly divided into a sham rTMS group, an rTMS group and a combined group, each of 25. In addition to 40 minutes of routine rehabilitation daily, including balance training, transfer training, muscle strength training, and proprioceptive training five times a week for 4 weeks, the sham rTMS group and rTMS group received sham or genuine rTMS. The combined group received 20 minutes of rTMS followed by mCIMT training 30 minutes later. The treatment was performed once a day, 5 days a week for 4 weeks. Before and after the treatment, all groups were evaluated using the Fugl-Meyer lower extremity assessment, the Berg balance scale, a 10-metre walk test and the modified Barthel index.Results:Significant improvement was observed in the average scores of all three groups in all of the assessments. The combined group′s averages were, however, significantly better than those of the other two groups.Conclusion:Supplementing mCIMT with rTMS can better improve the walking and other abilities in the activities of daily living of stroke survivors.
