Objective To investigate the clinical efficacy of neoadjuvant chemotherapy regimens of TA or AC in the treatment of locally advanced triple negative breast cancer. Methods Data of 99 women with stageⅡ/ Ⅲ locally advanced triple negative breast cancer treated in the Centre Hospital of Cangzhou from Jan. 2006 to Dec. 2011 were retrospectively analyzed. These patients were divided into two groups based on the regimen of the neoadjuvant chemotherapy. Fifty-two cases were received TA regimen(Docetaxel 75 mg/ m2 and pirarubicin 50 mg/ m2 )and 47 cases were received AC( pirarubicin 50 mg/ m2 ,cyclophosphamide 600 mg/ m2 ). IV drip infusion was administered in both groups for 4 cycles before surgery,with 3 weeks for each cycle. The efficacy after treatment,the 2 year recurrence rate and overall survival rate after operation were compared between the two groups. Results The response rates in TA group were 88. 46% ,higher than that of AC group(57. 45% ),and the difference was statistically significant(χ2 = 12. 260,P < 0. 001). Furthermore,the rate of pathological grade 4 and 5 in TA group were 42. 3%(22 / 52)was superior to AC group(23. 4%(11 / 47);P = 0. 046). The 2-year recurrence rate and survival rate in TA group were 23. 08%(12 / 52)and 84. 62% ,as same as that in AC group ((27. 66%(13 / 47)and 80. 85% ;χ2 = 0. 400;P = 0. 53). Conclusion TA and AC are both effective in terms of females with stage Ⅱ/ Ⅲ locally advanced triple negative breast cancer treat with neoadjuvant chemotherapy. Moreover,TA is superior to AC. However,there is no statistical difference of 2-years recurrence rate and survival rate between two groups.

Objective:To observe the changes of left ventricular energy loss(EL) and apical wall shear stress(WSS) in patients with ventricular aneurysm by using vector flow mapping (VFM).Methods:Twenty-seven patients with ventricular aneurysm were selected as the case group, and they were divided into the ventricular aneurysm group(16 cases) and ventricular aneurysm thrombus group(11 cases) according to whether the apex of the heart was accompanied by thrombosis. Twenty healthy people were collected as the control group. Ventricular structure and cardiac function parameters were measured and the VFM offline analysis was performed. Systolic and diastolic phases were determined based on time-flow curve(T-F curve) and the open-close of valves, the corresponding left ventricular energy loss and the parameters of the WSS of the apex segment of the heart were obtainedand then compared between groups.Results:①In diastolic and systolic phases, EL values of left ventricular apical segment in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than that in control group (all P<0.05). ②In diastolic phase, the peak WSS values of septal apical, lateral apical and anterior apical segments in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than those in control group (all P<0.05), and the mean WSS of anterior apical segment in aneurysm group was lower than that in control group ( P<0.05). ③In systolic phase, the peak WSS values of anterior wall in ventricular aneurysm group and ventricular aneurysm thrombus group were lower than those in control group, and the mean WSS of anterior wall in ventricular aneurysm group was lower than that in control group (all P<0.05). The mean WSS of anterior wall in ventricular aneurysm thrombus group was higher than that in ventricular aneurysm group( P<0.05). Conclusions:VFM technology can quantitatively evaluate the EL and WSS of patients with left ventricular aneurysm, and provide a new perspective for further understanding of intracardiac hemodynamics in patients with left ventricular aneurysm with or without thrombus.

Objective To explore the clinical significance of detecting serum levels of IL-6 and TNF-α in patients with intracranial hemorrhage.Methods The serum levels of IL-6 and TNF-α in different period were detected in patients with intracranial hemorrhage, by enzyme-linked immunosorbent assays (ELISA), and compared with those of healthy subjects (the control group).ResultsThe serum levels of IL-6, TNF-α in the severe and slight patients of study group on 1st, 3rd, 5th and 7th were signiifcantly higher than those in the control group (all withP<0.05). The serum levels of IL-6, TNF-α in the severe patients of study group were signiifcantly higher than those in slight patients of study group (all withP<0.05) on 5th and 7th. The serum levels of IL-6 and TNF-α in dead cases on 5th, 7th days admission were significantly higher than those in survival cases (P<0.05). The serum levels of IL-6 was positively correlated with TNF-α (r=0.721,P<0.05).Conclusion The detection of dynamically serum levels of IL-6 and TNF-α is of great clinical value for assessing the disease development therapeutic efifcacy and prognosis of brain injury patient with intracranial hemorrhage.

Objective To investigate the effect of gastrointestinal Roux-en-Y gastric bypass surgery on blood sugar and insulin function of patients with type-2 diabetes mellitus.Methods Twenty-seven cases of gastric cancer patients with type-2 diabetes and undergone Roux-en-Y bypass the gastrointestinal treatment in the centre hospital of Cangzhou were selected as our subject.Body mass index (BMI),Glycosylated hemoglobin (HBA1c),Fasting and glucose (FPG),fasting insulin (FINS),Fasting C-peptide (FCP) levels were measured.Glucose (2 hPG),insulin (2 hINS) and C-peptide (2 hCP) levels were detected after 2 h for oral use 75 g glucose.Homeostasis model was applied to assess insulin resistance index (HOMA-IR).Results No significant change was seen in terms of BMI between before and after surgery.Compared to before surgery,the levels of FPG((7.58 ±0.84) mmol/L),2 hPG((10.43 ± 1.88) mmol/L),HbA1c((7.56 ± 1.15)％) and HOMA-IR(4.55 ±0.76) were lower in patients at 3 months after surgery ((9.93 ± 1.57) mtmol/L,(13.89± 2.13) mtmol/L,(9.88 ± 1.66) ％,(4.55 ± 0.76),respectively,P ＜ 0.05 or P ＜ 0.01).FPG ((6.56± 0.80) mmol/L),2 hPG ((8.57 ± 1.32) mmol/L),HbA1 c ((6.37 ± 1.24) ％),HOMA-IR (4.03 ± 0.45)of patients after 6 months were lower than that of before surgery and 3 months after surgery (P ＜ 0.05 or P＜0.01).However,the levels of FINS ((13.67 ± 1.96) mU/L),FCP((2.62 ±0.87) μg/L),2 hINS((49.91± 5.14) mU/L) and 2 hCP ((6.28 ± 1.65) μg/L) were higher in patients with 3 months after surgery compared to that of before surgery ((11.08 ± 1.69) mU/L,(1.78 ± 0.61) μg/L,(36.05 ± 4.03) mU/L,(4.28 ± 1.48) μg/L,P ＜ 0.01).Meanwhile those indices after 6 months (FINS:(15.88 ± 2.05) mU/L,FCP:(3.30 ±0.68) μg/L,2 hINS:(67.40 ±5.68) mU/L,2 hCP:(9.39 ± 1.52) μg/L) were higher than that of before surgery and 3 months after surgery(P ＜ 0.01).Conclusion Roux-en-Y gastrointestinal bypass can effectively reduce blood sugar level and improve the situation of Pancreatic Beta-cell function of gastric cancer patients with type-2 diabetes.

Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.
