Objective To analyze the pathologic and biology features and prognosis of HER-2,ER and PR negative breast cancer(TNBC).Methods Clinic pathologic data of 329 breast cancer patients was retrospectively analyzed. The expression of HER-2, ER, PR and P53 was determined by immunohistochemistry. The patients were divided into three groups, including TN group [ HER-2 (-), ER (-), PR (-)], HER-2 group [HER-2(+),ER(-),PR(-)] and HR group [ER(+),PR(-) or (+),HER-2(-) or (+) ].The pathology and biology features and P53 masculine expression of the three groups were compared.The 5-year overall survival and disease free survival were analyzed by Kaplan-Meier method.Results Of the 329 patients, 20.97% (69/329) was TN group, 34.04% (112/329)was HER-2 group, and 44.98% (148/329) was HR group.The percentage of with lymph node metastasis in TN group 55.07% (38/69) was higher than that in HER-2 group 42.86% (48/112) and HR group 43.24% (64/148) (χ2 = 12.57, P ＜ 0.05).The rates of P53 positive, operation recurrence and metastasis in TN group were 44.93%, 27.54% and 20.29%, which were higher than that in HER-2 group (20.54% ,16.07%,16.96%) and HR group (18.24%, 12.84%, 10.81%) (χ2=12.23, 8.36, P ＜0.05).The ratio of tumor ≥5cm, Ⅲ stages, Ⅲ grade and soakage canula cancer among three groups had statistical difference (χ2 = 7.25,8.79,9.23,8.48, P ＜ 0.05).The 5-year overall survival in three groups were 75.36%,82.14% ,85.14% and disease free survival were 68.12% ,78.57% ,82.43% (χ2 =8.52, P ＜0.05).Conclusion The pathology and biology traits of TNBC were high rate of P53 (+) and recurrence and lymph node metastasis.The most important factor for poor prognosis of TNBC was the low rate of disease free survival for 5 years.

Objective To evaluate the left ventricular function and the synchrony of myocardial ischemic segments in patients with coronary heart disease (CHD) after PTCA and stent implantation by quantitative tissue velocity imaging (QTVI). Methods Thirty-six patients with isolated left anterior descending stenosis (≥75%) were examined by QTVI three days before, one week and one month after successful PTCA and stent implantation to measure the following items of 5 different left ventricular segments: peak systolic velocity( Vs), early diastolic velocity (Ve), late diastolic velocity (Va), time to peak systolic velocity(Ts). Then the coefficient of variation (SD/mean) of the 5 different Ts were calculated.Results The value of Vs,Ve and Va were decreased and the Ve/Va ratio was reverses three days before PTCA + stent. Compared with that before PTCA + stent,the value of Vs and Ve were increased significantly in one week ( P ＜0. 05) and one month( P ＜0.01 ) after PTCA + stent,respectively,the value of Va was not statistically significant. Ve/Va ratio was recovered in one week after PTCA treatment. Ts and Ts-SD were shorted dramatically in one week( P ＜0. 05) and one month( P ＜0.01 ) after PTCA + stent compared with that before PTCA + stent in which Ts were prolonged more than 33 ms. Conclusions QTVI can quantitatively assess the left ventricular function and the synchrony of myocardial ischemic segments, and can be used to real-time detect the changes of function and synchrony of left ventricle after PTCA and stent implantation.

Objective To investigate the effects of indirubatin derivative E804 on proliferation and migration of non-small cell lung cancer(NSCLC)A549 cells,and to elucidate the possible mechanism of Nrf2-HO-1/GPX4 pathway.Methods Lung cancer A549 cells were used as the cell model.The proliferation and migration of differ-ent specific inhibitors(Nec-1,CQ,Z-VAD,DFO,Fer-1 and Lip-1)in 0,10 μmol/L E804 and 10 μmol/L E804+groups were observed by MTT and cell scratch assay.The contents of reactive oxygen species(ROS)were de-tected by DCFH-DA fluorescence probe method,the contents of Fe2+were detected by colorimetric method,the contents of reduced glutathione(GSH)were detected by spectrophotometry,and the contents of malondialdehyde(MDA)were detected by micromethod.The expression levels of SLC7A11,Transferrin,GPX4,SLC40A1,Nrf2 and HO-1 were detected by Western blot in cells of 0,2.5,5 and 10 μmol/L E804 groups.Results Compared with the control group(0 μmol/L E804),2.5,5 and 10 μmol/L E804 significantly increased intracellular ROS,Fe2+and MDA levels,and decreased intracellular GSH content(P＜0.01).Meanwhile,the expression levels of SLC7A11,GPX4,SLC40A1,Nrf2 and HO-1 significantly decreased(P＜0.01),and the expression level of Transferrin increased(P＜0.05).Compared with the 10 μmol/L E804 group alone,the apoptosis inhibitor(Z-VAD)group and the ferroptosis inhibitor(DFO,Fer-1 and Lip-1)group could significantly reverse the inhibition of proliferation and migration of A549 cells by 10 μmol/L E804(P＜0.01).Conclution E804 can induce ferrop-tosis and inhibit the proliferation and migration of A549 cells,which may be related to the inhibition of Nrf2-HO-1/GPX4 pathway.

Objective:To observe the effects of Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction in treating chronic heart failure with syndrome of cold phlegm obstructing lung. Methods:Eighty-six chronic heart failure patients from January of 2017 to December of 2018 in our hospital who met the inclusion criteria were selected and divided into 2 groups according to the random number table method with 43 patients in each group. The control group was treated with conventional therapy, and the observation group was orally treated with Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction. Both groups were treated for 3 months. Then scored the symptoms of cold phlegm obstructing lung from four aspects: palpitations, cough and asthma, uria and edema, and sputum. The ultrasonic cardiogram was used to detect the left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF). The ELISA method was used to measure levels of vascular pseudohemophilia factor (vWF),endothelin-1 (ET-1) and serum levels of total antioxidant capacity (TAC), lipid peroxide (LPO), SOD, MDA. The efficacy was evaluated. Results:The total effective rate of the observation group was 90.7% (39/43), significantly higher than that of the control group as 69.8% (30/43), and the difference between the two groups was statistically significant ( χ2=4.692, P=0.030). After the treatment, scores of palpitation, cough and asthma, urine and sputum in the observation group were obviously lower than those of the control group ( t value were 7.621, 7.033, 6.831, 6.635, respectively, all Ps<0.01); the LVEDD (51.41 ± 5.69 mm vs. 58.49 ± 6.77 mm, t=9.809), LVESD (40.04 ± 4.48 mm vs. 43.25 ± 5.21 mm, t=6.776) of the observation group were significantly lower than that of the control group, and while LVEF (50.16% ± 5.89% vs. 45.87% ± 5.16%, t=7.761) was significantly higher than that of the control group ( P<0.01). Plasma levels of vWF (103.55% ± 11.98% vs. 138.11% ±15.71%, t=41.453) and ET-1 (67.05 ± 7.18 pg/ml vs. 81.72 ± 10.03 pg/ml, t=18.990) in the observation group were significantly lower than that of the control group ( P<0.01). The serum levels of TAC and SOD levels in the observation group were significantly higher ( t value were 4.662, 13.331, respectively, all Ps<0.01), while LPO and MDA levels were significantly lower than the control group ( t value were 4.982, 4.031, all Ps<0.01). Conclusions:The Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction in treating chronic heart failure can improve the heart function and symptoms with syndrome of cold phlegm obstructing lung, and increaseclinical efficacy.

Worster-Drought syndrome (WDS) is a special and rare type of cerebral palsy, which is characte-rized by pseudobulbar palsy, selective weakness of the muscles of the lips, tongue, and soft palate, dysarthria, dysphagia, salivation, and jaw spasm.The onset of WDS is linked with a variety of prenatal, intrapartum and postnatal factors.The report of family cases of WDS suggested the genetic predisposition.Although there is no cure at present, early genetic counseling, early diagnosis and intervention can reduce the morbidity of offspring and improve the symptoms of children with WDS, which will greatly reduce the burden on the family and society in the future.In the present study, this paper aims to explore the etiology, pathogenesis, clinical manifestation, imaging examination, diagnosis, disease spectrum and current treatment of WDS, thus improving the diagnostic and therapeutic efficacy.
