Objective To investigate the expression and the significance of a group of metastasis-associated proteins in invasive ductal breast carcinoma(IDC).Methods Tissue microarray containing 247 IDC specimens was constructed.The expressions of ?-B crystallin,CD44v6,MMP-2 and TIMP-2 were detected by immunohistochemistry,and the relation between the expression of these proteins and the clinicopathologic character was analyzed.Results(1) The expression rates of ?-B crystallin,CD44v6,MMP-2 and TIMP-2 in IDC were 70.0%,61.5%,57.5% and 57.1% respectively,and significantly higher than those of normal breast tissues(P

Objective To explore the etiology of lumbar degenerative spondylolisthesis(DS)by analyzing its CT manifestations.Methods The location,degree and angle of inclination of lumbar facet joints were measured in 125 cases with 131 spondylolisthesis.Results The angle of inclination of lumbar facet joints was

Objective:To analyze the prognostic factors in patients with metastatic breast cancer (MBC). Methods:A total of 205 patients with pretreated MBC were included in this study. These patients were admitted to the Tianjin Medical University Cancer Insti-tute&Hospital and had undergone radical surgery of breast cancer between January 2008 and December 2010. The clinicopathologic information of the patients was collected in this retrospective analysis. Results: The median overall survival of the patients was 32 months (1 month to 132 months). Luminal A, Luminal B, HER-2 overexpression, and triple-negative patients had a median overall sur-vival of 36 months (4 months to 132 months), 32 months (7 months to 122 months), 29 months (1 month to 85 months), and 24 months (1 month to 98 months), respectively. Univariate analysis showed that lymph node metastases, clinical stage, molecular type, visceral disease, first multiple metastatic sites, and shorter metastasis-free interval were significantly associated with poor outcomes. In multivar-iate analysis, lymph node metastases, clinical stage, molecular type, visceral metastasis, and the number of first metastatic sites were significant predictors of patient survival. Conclusion:Lymph node metastasis, clinical stage, triple-negative breast cancer, and visceral metastasis were used as independent poor prognostic indicators for survival in patients. Results of this study may assist physicians in evaluating the survival potential and determining the appropriate therapeutic strategy for MBC patients.

Objective To investigate the correlation between serum cystatin C(Cys-C)and renal function in patients with renal damage secondary to cirrhosis.Methods 129 patients with liver cirrhosis were selected,according to the measured glomerular filtration rate (GFR) as the gold standard for evaluation of renal function,patients were divided into group A(cirrhosis with normal renal function),group B(cirrhosis following renal insufficiency),group C (cirrhosis secondary to renal failure).The concentration of Cys-C was compared among three groups,and the serum creatinine(Scr),serum proteins ball micro β2 (β2-MG),creatinine clearance (Ccr) were detected.Results Cys-C,Scr,β2-MG,Ccr and other indicators of A,B,C three groups increased or decreased with the severity of impaired renal function(t =6.65,6.85,6.58,4.54,all P ＜ 0.05).The abnormal detection rates of Cys-C,Scr,Ccr,β2-MG in A group were 31.1％,11.1％,8.9％,26,7％,those in B group were 83.7％,30.2 ％,34.9％,46.5％,those in C group were 100.0％,85.4％,87.8％,95.1％.Conclusion Serum Cys-C concentration is a sensitive marker to evaluate glomerular filtration,it has accurate and reliable clinical significance in the early diagnosis of liver cirrhosis secondary to kidney damage.

Objective To systematically review the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS)for post-stroke dysphagia. Methods The clinical trials about rTMS for post-stroke dysphagia were searched on Pubmed,EMbase,MEDLINE,Cochrane library,China National Knowledge Infrastructure (CNKI),Chinese BioMedical Literature Database on disc (CBMdisc),and Wanfang database with computers. Two independent reviewers selected the literatures by the inclusion and exclusion criteria,data extraction and cross-checking,and then conducted the analysis. Results A total of seven trails (228 patients,136 of them in a rTMS group and 92 in a control group)were included. Four randomized controlled trials (RCTs)were used for Meta-analysis (54 patients in the rTMS group,42 in the control group). The other three non-RCTs were only reviewed systematically. (1)Meta-analysis showed that the improvement of swallowing function score after rTMS was better than that of the control group (SMD=1. 73,95%CI 0. 45 to 3. 01;P=0. 008). (2)After high-frequency rTMS (>1 Hz),there was significant difference in the improvement of swallowing function score between the two groups (SMD=1. 60,95%CI 0. 10 to 3. 11;P=0. 04). Compared to the control group,there were also significant differences in the improvement of some swallowing function scores in low-frequency rTMS (1 Hz),suggesting the potential advantages of low-frequency therapy. (3)After rTMS,there was no significant difference in the improvement of Barthel index in patients with stroke compared with the control group (MD= -21. 60,95%CI-36. 21 to-7. 00;P=0. 004). (4)In terms of adverse reactions,seven trials did not report any adverse events, such as headache,tinnitus or epilepsy,etc. Conclusion Using rTMS may significantly promote the recovery of swallowing function for patients with post-stroke dysphagia,and it is both safe and effective.
