Among the different x-ray features of breast carcinoma, mass and calcification are the most significant reference parameters in the screening and diagnosis of early carcinoma. Mammographic follow-up after conservation therapy is the other important value of mammography for breast carcinoma. Calcification is the most important sign to show residue or recurrence of conservation therapy.

Objective In order to determine the effect of colchicine(Col) on the changes of serum activity of tumour necrosis factor (TNF) induced by lipopolysaccharide(LPS) in rabbits.Methods Twelve New Zealand white rabbits were equally divided into 2 groups, namely group A and group B. Rabbits in group A were intravenously administered with 0.2ml/ kg of normal saline (NS) from 67h before LPS inje ction, while those in group B were given 0.5mg/ kg of Col instead of NS at the same time course.Endotoxic shock was induced by intravevous injection of 2?g/ kg of LPS after the challenge by Bacillus Calmette Gu?rin(BCG). Results Prior infusion of Col significantly decreased the peak levels of serum TNF activity ( P

Objective To investigate the value of microwave ablation in the treatment of hepatocellular carcinoma in the caudate lobe.Methods We retrospectively analyzed the data of patients with hepatocellular carcinoma in the caudate lobe treated primarily by microwave ablation from January 2011 to May 2016 in our department,and explore the safety,efficacy of microwave ablation (MWA).Results The 11 patients had been treated with microwave ablation procedure in 13 lesions,through caudate lobe epigastric puncture in 9 cases and intercostal puncture in 2 cases.A total of 2 cases did not reach the technical success due to one case treated by radiation therapy,and the other treated by repeated MWA.However,the repeated MWA of that patient failed to reach the technical success.And the effective rate of treatment was 81.8% (9/11).Following up to October 2016,the average follow-up time was (31.5±15.4) months.There were 1 patient with extrahepatic metastasis and 4 cases of patients with intrahepatic distant recurrence,among which 3 cases underwent MWA treatment again and 1 case underwent radiotherapy.Conclusion Microwave ablation is a safe and effective therapy option for the Caudate Lobe tumor.

Objective To study the effect of clopidogrel on different CYP2C19 genotypes and platelet reactivity in acute cerebral infarction patients with antiplatelet aggregation.Methods Four hundred and seventy-four cases of cerebral infarction patients in Beijing Tiantan Hospital Affiliated to Capital Medical University from April 2015 to April 2016 were collected.CYP2C19 genotype was determined,and the genotype was divided into the wild type group,the heterozygous type group and the mutant homozygous group.Platelet aggregation inhibition rate(ADP%) and platelet reactivity index induced by ADP were detected.Patients were divided into clopidogrel resistance group(group CR) and non resistant group according to whether ADP% was less than 30.SPSS 16.0 statistical software was used for statistical analysis,the comparison between groups using independent samples t test,chi square test and multivariate analysis using Logistic regression analysis,when P<0.05 difference was statistically significant.Results Among the 474 patients,204 cases(43.04%) were divided into wild-type group,and 204(43.04%) and 66(13.92%) were divided into the mutant heterozygous group and mutant homozygous group.In Chi square test analysis,clopidogrel resistance group and non resistance group CYP2C19 genotype distribution was significantly different(χ2=6.658,P=0.036).CR group angle(α) values((68.87±5.47)°) and MA((66.77±6.25) mm) were higher than that of CS group ((66.55±6.05)° and (63.30±5.66) mm,t=2.199,3.387,P=0.029,0.001).The multivariate logistic regression analysis showed that OR of angle level was 1.028,95%CI was 0.929-1.137 (P=0.595);OR of Ma level was 1.561,95%CI was 0.785-0.970 (P=0.012).Conclusion The effect of clopidogrel on platelet aggregation in patients with acute cerebral infarction is decreased by CYP2C19 gene mutation.CYP2C19 mutant allele is a risk factor for clopidogrel resistance.Angle (α) value and MA value are the risk factors for the diagnosis of CR in the patients with acute cerebral infarction,and the risk of clopidogrel resistance increased when the patients′ Angle (α) value and the value of MA increased.MA value as a predictor of CR and the screening tool has a certain value.

Objective To find the key miRNA that relative to peritoneal fibrosis associated with peritoneal dialysis (PD) by microarray technology,and verify its expression in vitro and in vivo.Methods The peritoneal fibrosis mouse model associated with PD were established by intraperitoneal injection of lipopolysaccharide (LPS)+ 4.25% peritoneal dialysate.The expression of miRNA was detected by microarray in peritoneal tissues.The expression of miRNA profiles between fibrotic and normal peritoneal tissues was compared.The differentially expressed miRNA (miR-200a) was validated by real-time PCR in lager sample size cohorts.The expressions of miR-200a were also detected in the epithelial-mesenchymal transition (EMT) process of human peritoneal mesothelium cells.Results In mice model of PD,peritoneal tissue was markedly thickened and with a massive extracellular matrix accumulation.In contrast with control,the expression level of epithelial marker E-cadherin was significantly decreased,α-SMA,Col-Ⅰ and FN were remarkably increased (P < 0.05).By miRNA microarray analysis,miR-200a was significantly down-regulated (3.31 folds change,P < 0.05) in fibrotic peritoneal tissues.The down-regulated expression level of miR-200a was also validated by realtime PCR in larger cohorts (P < 0.05).Then,the expression level of miR-200a was detected in the EMT process of human peritoneal mesothelium cells.During the process of TGF-β1 induced EMT,miR -200a was significantly down-regulated compared with the control (P < 0.05).Conclusions Downregulated expression of miR-200a was observed both during peritoneal fibrosis and TGF-β 1 induced EMT in vivo and in vitro,suggesting that miR-200a may be involved in the peritoneum fibrosis by regulating the target genes of EMT.

Objective To investigate the clinical features and current therapy of atrial fibrillation (AF) of inpatients in Urumqi,China.Methods The clinical data of inpatients diagnosed with AF from January,2008 to December,2012,in 12 hospitals in Urumqi were retrospectively analyzed.Results Totally 1 310 AF inpatients were enrolled in this study with the age of (64.8 ±3.3) years old and a men to women ratio of 1.39.Most patients were in age groups of 61-70 years (26.5%) and 71-80 years (27.6%).More patients with paroxysmal AF were at cardiac function class Ⅰ-Ⅱ (75.2%),while more patients with persistent AF were at cardiac function class Ⅲ-Ⅳ (31.0%) (both P values < 0.05).The most common co-morbidities of AF were hypertension (49.2%),coronary heart disease (38.5%),diabetes mellitus (20.1%).Compared with patients of chronic AF,the patients of paroxysmal AF had higher success rates in amiodarone conversation and sinus rhythm maintenance after ablation (44.8% vs 29.9%,87.5% vs 68.9%,P values < 0.05).Among the 1 310 inpatients,992 patients (75.7%) received antithrombotic therapy.There were statistically significant differences in CHA2DS2 score and incidence rate of cerebral infarction among patients receiving aspirin,warfarin or rivaroxaban/other anticoagulation drugs [2 (1,3) vs 3 (2,4) vs 3 (2,5) and 6.3% vs 23.8% vs 30.2%,both P values <0.05].Conclusion Our results of AF inpatients' age,gender,related disease distribution,AF types,incidence of stoke,therapeutic and epidemiological features are in accordance with the domestic and abroad reports.
