Objective To explore the correlation between TOP2A gene expression and TCM constitutional types of patients with triple-negative breast cancer.Methods The questionnaire for constitution of Chinese medicine was used to identify the TCM constitutional types of 71 patients with triple-negative breast cancer and TOP2A gene alterations were quantified by real-time PCR. 2-ΔΔCt was used to analyze the expressions of each group. SPSS17.0 was employed to analyze the correlation between TOP2A gene amplification and TCM constitutional types.Results Totally 71 patients were divided into general type (0 case), Qi deficiency type (18 cases), Yang deficiency type (10 cases), Yin deficiency type (12 cases), Qi stagnancy type (7 cases), blood stasis type (10 cases), phlegm wet calculus type (8 cases), damp-heat type (6 cases), and special type (0 case). All of them were biased constitutional types, of which Qi deficiency constitution (25.35%), Yin deficiency constitution (16.90%), blood stasis constitution (14.08%) took the majority. TOP2A gene amplification was negative correlated with each constitutional type (P<0.05).Conclusion Biased constitutional types were the main types of TCM constitutional type of patients with triple-negative breast cancer. The main three biased constitutional types of triple-negative breast cancer were Qi deficiency constitution, Yin deficiency constitution and blood stasis constitution. TOP2A gene expression in patients with triple-negative breast cancer was normal or less expressed, which predicted low chemotherapy sensitivity and poor prognosis.

ObjectiveTo compare the significance of anti-cmDNA antibody in systemic lupus erythematosus (SLE) patients detected with IIF on human's B lymphoma cell line Raji and promyelocytic line HL60.The diagnostic value of anti-cmDNA antibody in SLE was also explored.MethodsThree hundred and six patients with SLE were included in this study.As control groups,we included 192 patients with other rheumatic diseases and 50 healthy controls.The testing method for anti-cmDNA antibody was set up.The assessment of the significance of anti-cmDNA antibody in SLE detected with IIF on cell line Raji and HL60 was carried out andthe diagnostic value of anti-cmDNA antibody in SLE was investigated.ANA and antidsDNA antibody were measured by IIF at the same time.Anti-Sm was measured by immuno-diffusion andWestern blotting.AnuA was tested by enzyme linked immunosorbent assay.The statistical methods used in this study including McNemar X2 test,Spearman related test and Logistic regression analysis.Results The fluorescence brightness of Raji cell line was stronger than HL60 cell line.There was no statistically significant difference in the sensitivity and specificity of anti-cmDNA antibody in SLE detected with IIF with Raji or HL60 cell lines (P＞0.05).The sensitivity of anti-cmDNA antibody detected with IIF on Raji cell line was higher than anti-dsDNA antibody and anti-Sm antibody(P＜0.01),while the specificity of anti-cmDNA antibody was similar to anti-dsDNA antibody (P＞0.05) and was lower than anti-Sin antibody (P＜0.01).The sensitivity of anti-cmDNA antibody was similar to AnuA(P＞0.05) and the specificity was lower than AnuA (P＜0.01).The sensitivity of ANA was higher than anti-cmDNA antibody (P＜0.01) and the specificity was much lower than anti-cmDNA antibody(P＜0.01).The sensitivities of anti-dsDNA antibody,anti-Sm antibody and AnuA were much higher when combined with anti-dsDNA antibody than any one antibody only (P＜0.05).Anti-cmDNA antibody was correlated with mucosa ulcer in SLE patients(OR=2.343,P=0.029).The ESR of SLE patients was also correlated with anti-cmDNA antibody(OR=l.031,P=0.012).Anti-cmDNA antibody was not correlated with SLEDAI (r=0.070,P=0.600).ConclusionRaji cell line is better than HL60 cell line in detecting anti-cmDNA antibody with IIF.Anti-cmDNA antibody has higher sensitivity and specificity in SLE.Combined detection of anti-cmDNA antibody and other autoantibodies can further improve the diagnostic accuracy of SLE.

Objective To compare the significance of DNA-associated autoantibodies to cell membrane(cmDNA)in systemic lupus erythematosus(SLE)detected with indirect immunofluorescence on human B lymphoma cell line Raji and pmmyelocytic line HL60.Methods Indirect immunofluorescence assay both on cell line Raji and HL60 was used to measure anti-cmDNA antibodies in sera of 306 SLE patients.192 patients with other rheumatic diseases and 50 healthy controls.Results Indirect immunofluorescence assay on cell line Raji was used to measure anti-cmDNA antibodies.72.5% SLE and 10.4% other rheumatic diseases were positive for anti-cmDNA,but negative in 50 blood donors(P<0.01).Indirect immunofluorescence assay on cell line HL60 was used to measure anti-cmDNA antibodies,76.1% SLE and 16.7% other rheumatic diseases were positive for anti-cmDNA,but negative in 50 blood donors(P<0.01).The sensitivity of anti-cmDNA were 72.5%and 76.1%,respectively.The specificity of anti-cmDNA was 91.7% and 86.8%,respectively.There was no significant difference in sensitivity and spocificity(P>0.05).The methods of culture,freeze and resuscitation on the two cells were similar.but cell line Raji was easier to resuscitate than cell line HL60.Observing with fluorescence microscope.we find that cmDNA was expressed on the both cells and the staining was stronger on cellline Raji than HL60.Conclusion Anti-cmDNA antibody has high positivity which is one of the most valuable marker in the diagnosis of SLE.We recommend to measure anti-cmDNA antibodies with indirect immunofluorescence assay on cell line Raji rather than HL60.

ObjectiveTo evaluate the safety, and the brief-and prolongedterm therapeutic efficacy for im- plantation of biodegradable stent Excel combined with Tirofiban made in China into patients with acute coronary syndrome(ACS). MethodA total of 301 patients were divided into Excel group (n = 100), Cypher group (n =102) and bare metal stem(BMS) (n = 99). The Tirofiban used in three groups was administered intravenously during and after operation.The loading dose of Tirofiban was 10 μg/kg given within 3 min followed by a Tirofiban intravenous maintenance infusion in 0.15 μg/(kg·min) with micro pump for 48 hours. Safety and efficacy were compared among three groups after stents implantation by the observation of TIMI flow, complication of bleeding, changes of platelet count, haematoglobin and hematocrit, incidence of angina, acute and subacute thrombosis inner stent and major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction and target ves-sel revascularization). Follow-up information got from out-patient clinic and telephone call including incidence of angina, MACE and rehospitalization were comapared sucessively 1 month, 6 monthes and 12 monthes after dis- charge. ResultsAmong there groups,there were no significant differences in demographics,and physical and lab-oratory findings before treatment. Successful rate of implantation was 100 percent and the TIMI flow of class Ⅲ was found in all patients. There was no complication of stroke and massive hemorrhage of gastrointestinal tract, and no significant differences in complication of bleeding, platelet count, hemoglobin and hematocrit after implantation. Incidence rates of acute thrombosis were 0, 0.98 and 1.01 percent in three groups, and there was no significant difference in acute thrombosis inner stent among three groups (P >0.05). The rates of angina, sub.acute stent thrombosis, MACE and rehospitalization among three groups had no differences at 1 month and 6 monthes follow-up (P > 0.05), but significant differences were not found until 12 monthes follow-up (P < 0.05). Conclusions Drug-eluting stent Excel with biodegradable polymer combined with Tirofiban made in China implanted in patients with ACS were capable of preventing acute and later thrombosis inner stent. This procedure had favourable safety, and brief-term and proionge-term therapeutic efficacy.

Objective To investigate the effects of metformin on the radiosensitivity of breast carcinoma cells with different estrogen receptors stasus (MCF-7 and MDA-MB-231) and to explore the underlying mechanisms.Methods Two cell lines,MCF-7 and MDA-MB-231 in logarithmic phase were divided into four groups:control group,drug group (mefformin),irradiation group and experimental group (irradiation plus metformin).MTT assay and the clonogenic assay were performed to evaluate the effects of metformin on the proliferation and survival of breast carcinoma cell lines,respectively.The change of cell cycle distribution and apoptosis rates were measured by propidium iodide (PI) and Hoechst 33342 staining analysis repectively.Western blot was used to detect the expression of p-AMPK and p-mTOR.Resutls Metformin could obviously inhibit the proliferation of the two breast carcinoma cell lines in a dose dependent manner.The cloning formation capacity was decreased in the group of metformin plus irradiation,which displayed the values of Dq,D0 and SF2 significantly lower than those of irradiation alone group (MCF-7:t =9.305,14.528,13.708,P ＜0.05;MDA-MB-231:t =19.560,16.893,36.048,P ＜0.05),and the sensitizing enhance rate (SER) of D0 were 1.29 and 1.21 for MCF-7 and MDA-MB-231 cell lines,respectively.Compared with irradiation alone,metformin plus irradiation obviously increased the proportion of cells in the G2/M phase in both cell lines (t =6.103,38.431,P ＜ 0.05).Metformin plus irradiation also enhanced radiation-induced apoptosis in both cell lines so that the apoptosis rates were higher than that in the metformin group or irradiation alone group (t =9.143,14.561,P ＜ 0.05).In MCF-7 cell lines,the expression of p-AMPK in the metformin combined with irradiation group was significantly higher than other treatment groups (t =35.194,8.647,10.316,P ＜ 0.05),but no significant changes of p-AMPK expression in MDA-MB-231 cell lines was observed (P ＞ 0.05).While inhibition of p-mTOR by metformin was observed in both cell lines (MCF-7:t =80.133,31.820,11.308,P＜0.05;MDA-MB-231:t=12.436,15.757,8.402,P＜0.05).Conclusions This study suggests that metformin possessed a strong radiosensitizing potential in both breast carcinoma cell lines of MCF-7 (ER positive) and MDA-MB-231 (ER negative).This radiosensitizing effect may result from the activation of AMPK or AMPK-independent pathway,inhibition of mTOR signaling pathway,and the enhancement of radiation-induced G2/M phase arrest and cell apoptosis after metformin treatment.

In previous study, the 150-ku oxygen-regulated protein(ORP150) was identified as a candidate glycoprotein related to hepatocellular carcinoma.In order to further validate the expression level of ORP150 in hepatocellular carcinoma, protein expression was determined by Western blot and cell immunochemistry, and messenger RNA(mRNA) expression was detected by quantitative real-time polymerase chain reaction.The effect of ORP150 on apoptosis and invasive potential of hepatocellular carcinoma cells was evaluated using the small interference RNA(siRNA) technique.Both the protein and mRNA expression levels of ORP150 were significantly upregulated in hepatocellular carcinoma cell lines compared with a non-tumor human liver cell line.After transfection with the specific siRNA of ORP150, significantly greater apoptosis of hepatocellular carcinoma cells was induced compared with untransfected cells.However, no significant effect on invasive potential was found.Overexpression of ORP150 was associated with hepatocellular carcinoma, and ORP150 might promote the proliferation of hepatocellular carcinoma cells by inhibiting apoptosis.ORP150 could be a potential therapeutic target for hepatocellular carcinoma.

Objective To analyze the risk factors of cortical micro-infarcts (CMIs) in patients with acute ischemic stroke and to evaluate the diagnostic value of 3.0 Tesla (T) magnetic resonance imaging (MRI) using double inversion recovery (DIR) sequence and 3-dimensional fluid attenuated inversion recovery (3D-FLAIR) sequence in CMIs in vivo.Methods One hundred and ten consecutive patients with acute ischemic stroke within 7 d of onset were chosen from August 2014 to July 2015;these patients were classified into CMIs group and non-CMIs group by results of 3.0 conventional T MRI,DIR-MRI and 3D-FLAIR-MRI.Baseline characteristics and risk factors were analyzed to investigate the independent risk factors of CMIs.The presence of CMIs was evaluated based on conventional T MRI,DIR-MRI and 3D-FLAIR-MRI.Results Of the 110 enrolled patients with acute ischemic stroke,CMIs were presented in 23.6％ patients (26/110).The age of patients from the CMIs group was significantly older as compared with that of patients from the non-CMIs group (67.65±10.37 vs.58.52± 11.24 years old,P=0.009).Patients from the CMIs group had significantly higher percentages of age＞65 years,age of 76-80 years,hypertension,history of cerebral ischemia and intracranial atherosclerosis than patients from non-CMIs group (P＜0.05).Multivariate Logistic regression analysis indicated that age＞65 years (OR=1.982;95％CI:1.362-2.889,P=0.010) and hypertension (OR=1.326;95％CI:1.022-1.682,P=0.026) were the independent risk factors of CMIs.The prevalence of CMIs detected by conventional sequence (10.9％) was significantly lower than that detected by DIR sequence (23.6％) or 3D-FLAIR sequence (20.9％,P=0.013 and P=0.043).Conclusions Age＞65 years and hypertension are independent risk factors of CMIs.DIR and 3D-FLAIR sequences at 3.0 T MRI substantially improve the sensitivity of detection of CMIs as compared with conventional MRI sequence.

Objective:To investigate the value of postoperative radiotherapy in patients with cT 1-2N 1M 0 breast cancer after neoadjuvant chemotherapy and modified radical mastectomy which postoperative pathology showed that the number of axillary lymph node metastases was 0-3. Methods:One hundred and twenty-eight patients diagnosed with cT 1-2N 1M 0 breast cancer admitted to our hospital from January 1, 2000 to December 31, 2014 were retrospectively reviewed. All patients underwent neoadjuvant chemotherapy and modified radical mastectomy. The number of postoperative axillary lymph node metastases was 0-3. According to whether there was postoperative radiotherapy or not, the whole group of patients was divided into radiotherapy group ( n=87) and non-radiotherapy group ( n=41). In the two groups after operation, there were 43 and 11 patients with 1-3 axillary lymph node metastases (ypN 1), while there were 44 and 30 patients without axillary lymph node metastases (ypN 0) respectively. The 5-year locoregional recurrence-free survival (LRFS) rate, disease-free survival (DFS) rate and overall survival (OS) rate were calculated by Kaplan-Meier method, and the differences were compared by log-rank test. Univariate analysis was performed to analyze the effects of clinical features and treatment on prognosis. Results:The 5-year LRFS rate, DFS rate and OS rate of 128 patients were 91.4%, 82.8% and 93.0% respectively. The 5-year LRFS rates of the patients in the radiotherapy group and the non-radiotherapy group were 94.3% and 85.4% respectively, and the difference was not statistically significant ( χ2=3.055, P=0.080). As well as the 5-year DFS rates were 89.7% and 68.3% respectively, and the difference was statistically significant ( χ2=9.312, P=0.005). The 5-year OS rates were 94.3% and 90.2% respectively, and the difference was not statistically significant ( χ2=0.810, P=0.368). In the subgroup analysis, the 5-year LRFS rates of the patients who had achieved ypN 1 in the radiotherapy group and the non-radiotherapy group were 93.0% and 72.7%, and the 5-year DFS rates were 88.4% and 63.6%, with statistically significant differences ( χ2=4.248, P=0.039; χ2=4.525, P=0.033). The 5-year OS rates were 90.7% and 81.8% respectively, and the difference was not statistically significant ( χ2=0.713, P=0.399). The 5-year LRFS rates of the patients who had achieved ypN 0 in the radiotherapy group and the non-radiotherapy group were 95.5% and 90.0% respectively, with no statistically significant difference ( χ2=0.872, P=0.350). The 5-year DFS rates were 90.9% and 70.0% respectively, with statistically significant difference ( χ2=5.439, P=0.019). The 5-year OS rates were 97.7% and 93.3% respectively, with no statistically significant difference ( χ2=0.876, P=0.349). The univariate analysis indicated that age ( χ2=11.709, P=0.001) and blood vessel invasion ( χ2=7.608, P=0.006) were significant influencing factors for 5-year LRFS rate. Postoperative radiotherapy ( χ2=9.312, P=0.002) was a prognostic factor for 5-year DFS rate. Age ( χ2=6.093, P=0.014) and hormone receptor status ( χ2=3.974, P=0.046) were prognostic factors for OS. Conclusion:For the cT 1-2N 1M 0 breast cancer patients with 1-3 positive axillary lymph nodes after neoadjuvant chemotherapy, postmastectomy radiotherapy has local control benefit, and it can improve DFS. However, the benefit of postoperative radiotherapy needs to be further investigated in patients with pathological negative axillary lymph nodes after neoadjuvant chemotherapy.
