Breast cancer has become one of the most common malignant tumors in female and endangered their health seriously.In recent years,the incidence of breast cancer continues to be uptrend and tend to be younger.As the treatment of breast cancer is more diversified and meticulous,the prognosis of breast cancer has been improved.When Dr Csatary found a farmer got gastric cancer was cured by Newcastle disease virus occasionally,Newcastle disease virus was widely studied as a novel kind of anti-tumor biologics.So Newcastle disease virus had become an effective new treatment method in breast cancer.This article briefly elaborates the profile of Newcastle disease virus,mechanism,the significance of researching and other aspects.

Breast cancer was a common malignancy in female and endangered their health seriously.In recent years,the incidence of breast cancer has been more and more and younger and younger.With breast cancer checked out widely,the diagnosis rate of the early breast cancer has been significantly increased,so that the prognosis of patients with breast cancer has been apparently improved.Currently,the majority of patients did not only require removing the total tumor completely,but also ensuring tihe quality of life to reduce the psychological pressure.What's morc,they required a better cosmetic result.Thus the conventional treatments (such as surgery,radiotherapy,chemotherapy,estrogen and progesterone) have not met their pursuit; the radiofrequency ablation is a better therapeutic method.I briefly describe its principlcs,methods,status,postoperation,complication and so on.

Objective To investigate whether black cohosh could be improve patients with breast cancer treated chemotherapy like-menopausal symptoms through a non-estrogen pathway.Methods We selected 120 patients with breast cancer dianosised and treated chemotherapy from January 2012 to June 2013 in four Affiliated Hospital of Harbin Medical,which were female patients,20-51 years,preoperative menopause,menstrual regularly,postoperative chemotherapy timely and regularly,and Kupperman score ≥ 15 points.All patients were randomized,double-blind divided into two groups,the experimental group was treated with medication Li Fumin Black Cohosh Extract,40 mg once daily,the other one was treated with placebo,40mg once a day.After 12 weeks,all patients were checked by estrogen hormones,gynecological ultrasound,the ultrasound of the other breast,Kupperman score,Then we make an assessment with those.Results During the experimental group and the control group,estrogen and endometrial thickness were within normal range,and there are not statistically significant difference between before and after medicine(P ＞ 0.05).What's more,before and after medication,the experimental group and the control group were not found new breast lumps.After taking medicine,the Kupperman score of experimental group was significantly lower than before treatment,the difference was statistically significant (P ＜0.05); however,there was not statistically significant difference between before and after medicine for the Kupperman score in control group(P ＞ 0.05).In experimental group,there are 5 cases of patients,which Kupperman is more 15 points,but lower than the score before taking medicine.Conclusions Black cohosh could improve like-menopausal symptoms of patients with breast cancer treated chemotherapy through a non-estrogen pathway,regardless of estrogen-receptor positive or negative,which has a good effection.

Objective: To study the effect of docetaxet (DOC) combined with 4-AP on human breast can-cer MCF-7 cells and to explore whether 4-AP could strengthen the effect of docetaxel. Methods: MTT assays were performed to investigate the effect of docetaxel, 4-AP and the combination of them on the proliferation of MCF-7 cells. Flow cytometry was employed to detect cell cycles and cell apoptosis after the cells were stained by PI alone or by Annexin-V and PI. Results: Docetaxel could significantly inhibit the proliferation of MCF-7 cells in a dose- and time- dependent manner. 4-AP could inhibit the proliferation of MCF-7 cells and the inhibitory rates were 11.9%±1.7%, 42.1%±3.2%, and 44.2%±1.6% at 24h, 48h and 72h after adding 4-AP. Moreover 4-AP (5mmol/L) could strengthen the effect of docetaxel. 4-AP (25μmol/L) could increase the effect of Docetaxel. Docetaxel at 5μmol/L could significantly increase the percentage of cells at G_2/M (53.58%± 1.44% vs. 8.83%±0.44%, P<0.01) and decrease the percentage of cells at G_0/G_1 (11.48%±0.14% vs. 63.89%±0.98%, P<0.01), indicating that docetaxel blocked MCF-7 cells at G_2/M phase. 4-AP at 5mmol/L could in-crease the percentage of MCF-7 cells at G_0/G_1 and decrease the percentage of cells at G_2/M (0.42%±0.17% vs. 8.83%±0.44%, P<0.05). Docetaxel could significantly increase late apoptosis and death of MCF-7 cells af-ter treatment over 24h (from 6.97%±0.75% to 20.77%±0.75%, P<0.05). Docetaxel combined with 4-AP could increase early apoptosis rate from 4.60%±0.91% to 12.20%±0.82% (P<0.05) and could increase late apopto-sis rate and death rate from 4.60%±0.91% to 12.20%±0.82% (P<0.05). Conclusion: Both docetaxel and 4-AP can inhibit the proliferation of MCF-7 cells. Docetaxel can increase the percentage of cells at G_2/M phase and 4-AP can increase the percentage of cells at G_0/G_1 phase. 4-AP could strengthen the inhibitory effect of docetaxel on the proliferation of MCF-7 cells through inducing cell apoptosis.

Objective To explore the CT and MR features of malignant peripheral nerve sheath tumor (MPNST) of adults.Methods The CT and MRI findings of 20 patients of MPNST confirmed by pathology were analyzed retrospectively.Results Among 20 cases,the lesions were located in the lower extremities (n=4),shoulder and spine (n=4),abdomen (n=3),chest wall (n=2),mediastinum (n=2),breast (n=1),prostate (n=1),scrotum (n=1),scalp (n=1),left maxillary sinus and orbital bottom (n=1).Nineteen cases appeared as solid masses and 1 case appeared as diffuse lesion.The maximum cross section of the lesions were about 1.41 cm× 1.42 cm-17.10 cm× 18.08 cm.Sixteen cases were ill defined margin and 4 cases were well-defined margin.CT scan showed 14 cases were lower density or isodensity and with patchy inhomogeneous density.Multiple calcification were found in 2 cases and osteolytic destruction were found in 7 cases.Enhanced CT of 10 cases showed solid component and gradually delayed enhancement,while cystic lesion and necrosis were not enhancement.The tortuous arteries were displayed in 7 cases.Seven cases were performed MRI and the lesions appeared as hypo-intensity on T1WI and hypo-intensity on T2WI with obviously high intensity of cystic component.Enhanced MRI of 3 cases showed significantly heterogeneous enhancement,cyst and necrosis had no enhancement.MR dynamic enhancement of 1 case showed time-signal intensity curve was platform type.DWI showed high signal.Conclusion MPNST has certain CT and MR characteristics which are helpful to improve the diagnostic accuracy.

Objective To evaluate the feasibility of dual-source computed tomography(DSCT)coronary angiography in a population with premature heart-beats.Methods Seventy patients with suspected coronary artery disease and premature heart-beats were routinely imaged on a DSCT scanner(Somatom Definition,Siemens AG,Germany).The images were reconstructed before and after ECG editing.Two readers independently assessed image quality of all coronary segments using a four-point grading scale from excellent(1)to non-assessable(4).The results ofthe two groups were compared with a paired t-test,and a P value of less than 0.05 Was considered significant.Results The mean heart rate during examination ranged from 49 to 111 bpm[mean(70.7±12.4)bpm].Twenty-eight of 70 patients with relatively small variability of the heart rate[(41.0±18.4)bpm]got diagnostic image quality without ECG editing.In other 42 patients with larger variability of the heart rate[(71.4±28.7)bpm],the meal image quality scores were 2.09±1.27 and 1.50±0.79 before and after ECG editing,there Was a significant difference(t=13.764,P＜0.01).The proportion of non-assessable segments Was reduced from 24.8%(154/620)to 3.4%(21/620)through ECG editing(X2=121.846,P＜0.01).Finally,the diagnostic image accounted 98.0%(1014/1035)in all segments of 70 patients.Conclusion DSCT can provide diagnostic images for patients with premature heart-beats.The image quality in patients with larger variability of the heart rate can be significantly improved through ECG editing.

Objective: To develop the Risk Assessment Scale of Severe Psychiatric Patients in Community and test its reliability and validity. Methods: A random sample of 860 severe psychiatric patients, which was selected from 8 communities in Chaoyang District of Beijing, completed the Risk Assessment Scale of Severe Psychiatric Patients in Community. The internal consistency reliability, the observer reliability, and the correlative coefficients between the total and items of the scale were analyzed, and the exploratory factor analysis was conducted. Results: (1) The Cronbach's coefficient of the scale was 0. 86, and the observer coefficient was 0.92. (2) The Spearman correlative coefficients between the total and items ranged from 0.40 ～ 0.56. (3) Exploratory factor analysis showed that the scale had 4 main factors, all of which could account for 68.14 percent of the whole variance, and the ten item loadings ranged from 0. 60 ～0.91. (4) The patient who scored higher than 35 was called high risk patient Causing trouble behavior of high risk patient was obviously higher than others. Conclusion: The results indicate that the Risk Assessment Scale of Severe Psychiatric Patients in Community has good reliability and validity. It can be used to assess the risk of severe psychiatric patients in community.

Objective To assess the value of color Doppler ultrasonogarphy in the diagnosis of subacute thyroiditis (SAT). Methods Sixty-eight patients of SAT and 30 patients with thyroid papillary carcinoma were included, and their imaging features were retrospectively reviewed. Results All the patients with SAT had either focal or diffuse hypoechogenicity of the thyroid lobes with rich blood supplying in the diseased region, among them 52 patients (76.47%, 52/68) had tenderness on palpation. Diffuse and focal lesions were found in 40 (58.82%, 40/68) and 28 patients (41.18%, 28/68). The boundary and shape of focal lesions had no diagnostic characteristics compared with those of thyroid papillary carcinoma. Punctate calcification and resistance index (RI) in the nodule were significant different between the SAT and thyroid papillary carcinoma (P＜0.05). Conclusion Color Doppler ultrasonography can display the features of SAT and is an effective method for the diagnosis of SAT.

ObjectiveTo evaluate the impact of patient's heart rate(HR)on coronary CT angiography(CTA)image quality(IQ)and reconstruction timing in dual-source CT(DSCT).Methods Ninety-five patients with suspicion of coronary artery disease were examined with a DSCT scanner(Somatom Definition.Siemens)using 32×0.6 mm collimation.All patients were divided three groups according to the heart rate(HR):group 1,HR≤70 beats per minute(bpm),n=26;group 2,HR＞70 bpm to≤90 bpm, n=37;group 3,HR＞90 bpm,n=32. No beta-blockers were taken before CT scan.50-60 ml of nonionic contrast agent were injected with a rate of 5 ml/s. Images were reconstructed from 10%to 100% of the R-R interval using single-segment reconstruction. Two readers independently assessed IQ of all coronary segments using a 3-point scale from excellent(1)to non-assessable(3)for coronary segments and the relationshiD between IQ and the HR. ResuitsOverall mean IQ score was 1.31 ±0.55 for all patients with 1.08±0.27 for group 1,1.32±0.58 for group 2 and 1.47±0.61 for group 3. The IQ was better in the LAD than the RCA and LCX(P＜0.01).Only 1.4%(19/1386)of coronary artery segments were considered non-assessable due to the motion artifacts.Optimal image quality of all coronary segments in 74 patients(77.9%)can be achieved with one reconstruction data set.The best IQ was predominately in diastote(88.5%)in group 1,while the best IQ was in systole(84.4%)in group 3. ConclusionsDSCT can achieve the optimal IQ with a wide range of HR using single-segment reconstruction. With the increasing of HR,the timing of data reconstruction for the best IQ shifts from mid-diastole to systole.

Objective To analyze the levels of serum thrombin-activatable fibrinolysis inhibitor ( TAFI) in patients with chronic hepatitis B ( CHB ) with different degrees of hepatic fibrosis , and to evaluate the value of TAFI in the evaluation of liver fibrosis .Methods Forty six patients with CHB who underwent liver biopsy from June 2016 to March 2017 in Zhejiang Provincial People' s Hospital were enrolled.According to liver fibrosis stage (S0-4), they were divided into mild liver fibrosis group (S0-1, n=16), significant liver fibrosis group (S2, n=15) and severe liver fibrosis group (S3-4, n=15).At the same time, 16 healthy subjects were randomly selected as health controls in the physical examination center of the hospital .Serum TAFI levels were analyzed in each group , and the receiver operating curve ( ROC) was used to evaluate the diagnostic value of TAFI in CHB patients with significant liver fibrosis and severe liver fibrosis (S≥2).The SPSS 23.0 software was used to analyze the data .Results Serum TAFI levels in the mild liver fibrosis group , significant liver fibrosis group , severe liver fibrosis group and health controls were (63.4 ±18.2), (43.8 ±20.4), (27.5 ±19.2) and (71.3 ±25.6) ng/mL, the difference between the four groups was statistically significant (F=13.512, P<0.01).The level of TAFI in the significant liver fibrosis group was lower than that in the healthy control group and the mild liver fibrosis group (t=3.283 and 2.822, P<0.01).The level of TAFI in the severe fibrosis group was lower than that in the significant liver fibrosis group (t=2.260, P<0.05).Serum TAFI levels were negatively correlated with liver fibrosis stage (r=-0.562, P<0.01).The area under the ROC curve of TAFI for predicting liver fibrosis (S≥2) was 0.832, and the sensitivity and specificity were 81.3％and 78.3％, respectively. Compared with the APRI score and the FIB4 index, the difference was not statistically significant ( P >0.05).Conclusion The serum TAFI level is negatively correlated with the degree of liver fibrosis in CHB patients, which has a good diagnostic value for liver fibrosis (S≥2) in patients with CHB.
