In order to explore the possibility of Xihuangwan (XHW)'s application in assistant therapy in patients with breast cancer, short- and long-term clinical efficacy were assessed in this study. Eighty and four patients with advanced breast cancer were selected in this study. They were divided into control group and treatment group randomly and evenly. All patients received surgical treatment followed by chemotherapy regimen composed of PTX + EPI + CTX (TEC regimen). Treatment group received additional assistant treatment of XHW. Short-term clinical efficacy was assessed by KPS, lesion stabilizing rate and side effects in 3-month follow-up study. Long-term clinical efficacy was assessed by overall survival (OS) and free-progression survival (FPS). KPS increased significantly after treatment in all patients (P < 0.05), more significantly in treatment group than in control group after treatment (P < 0.05); lesion stabilizing rate in treatment group increased significantly in treatment group than in control group (92.86% vs. 85.71%, P < 0.05); there was no significant difference between control group and treatment group in occurrence of side effects. Compared with control group, OS and FPS increased significantly in treatment group. Data in this study showed that XHW was suitable in treatment of advanced breast cancer due to its satisfactory short-term and long-term therapeutic effects.

Objective To investigate the value of vessel size index(VSI) in grading oligodendroglioma by vessel size imaging technique. Methods Twenty-four histologically confirmed oligodendroglioma cases were enrolled (13 gradeⅡand 11 gradeⅢ) . All patients underwent conventional MRI scanning, followed by multi gradient-echo spin-echo sequence from dynamic susceptibility contrast perfusion to generate VSI maps. Region of interests were contoured on VSI color maps to obtain hot-spot value of mean VSI of microvasculature (VSImean) and maximum VSI of microvasculature (VSImax). Paraffin sections of each case was stained with CD34 to acquire microvascular caliber (VShis). Pearson correlation analysis was used to evaluate the correlation between VSImean, VSImax and VShis respectively. Mann-Whitney U test was used to compare VSImean, VSImax and VShis between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis was performed to assess the effectiveness of VSImean, VSImax and VShis in grading oligodendrogliomas. Results Both VSImean and VSImax were strongly correlated with VShis (r=0.738, 0.705,P<0.05). For gradeⅡand Ⅲ oligodendrogliomas, VSImean were 38.93(17.96 to 81.18)μm and 91.49(36.94 to 144.68)μm, VSImax were 45.12(22.30 to 89.65)μm and 121.19(57.29 to 164.00)μm, VShis were 8.51(5.25 to 12.76)μm and 11.03(7.59 to 21.96)μm respectively. VSImean, VSImax, and VShis showed significant difference (Z=-3.505,-3.911, -2.729,P<0.05) between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis revealed that the optimal cutoff value, sensitivity, specificity and AUC of VSImean was 52.58 μm, 90.91%, 92.31%, 0.923 respectively, 81.18μm, 90.91%, 100.00%, 0.972 for VSImax, and 9.01μm, 90.00%, 84.62%, 0.838 for VShis respectively. Conclusions Vessel size imaging derived VSI correlated well with histopathology. It could provide valuable information in the pre-operative grading of oligodendroglioma.

Objective To explore the correlation of peritumoral brain edema( PTBE)size,histologi-cal grades and the expression rate of Ki-67 in gliomas. Methods The data and specimens about 74 cases of gliomas in People's Hospital of Xinjiang Uygur Autonomous Region during 2010-2013 were collected. All cases were confirmed by surgery and pathology. According to preoperative MRI,PTBE was graded. Immunohisto-chemical discriminate the expression of Ki-67. HE coloration distinguish the histological grades. Results In this study,90. 54%(67/74)patients occured PTBE,the incidence of PTBE inⅠ,Ⅱ,Ⅲ,Ⅳlevel of groups were 100%(3/3),78. 95%(15/19),83. 33%(15/18),100%(34/34). Ki-67 expression was positive in 75. 68%(56/74)patients,and the rates were 0,36. 84%(7/19),94. 44%(17/18),94. 12%(32/34) in Ⅰ,Ⅱ,Ⅲ,Ⅳ level of groups. The expression rate of Ki-67 was 57. 14%(4/7),60. 00%(6/10),and 80. 70%(46/57)in normal group,Ⅰ-level groups of PTBE,Ⅱ-level groups of PTBE. The result of Kruskal-Wallis H showed that the PTBE from different grades was statistically significant(H=11. 304,P=0. 010). The expression rate of Ki-67 in different grade gliomas was statistically significant(H=38. 530,P﹤0. 05), The difference of expression Ki-67 in gliomas of different PTBE was statistically significant( H=6. 478,P=0. 039). The result of Spearman rank correlation analysis showed that the PTBE level increased with the histo-logical grade up in gliomas(r=0. 385,P=0. 001). The expression rate of Ki-67 increased with the histologi-cal grade up in gliomas(r=0. 692,P﹤0. 05),and the expression rate of Ki-67 increased with the degree of PTBE up in glomas( r =0. 256,P =0. 028 ). Conclusion Accorrding to the PTBE size,the histological grades and proliferation ability of glioma can be judged pre-operation. Ki-67 can be used as the indicator of pro-liferation activity of tumor,and also be used as the important basis of histological grades.

Objective:To investigate the risk factors and predictive effect of lateral cervical lymph node metastasis of papillary thyroid carcinoma (PTC) by applying the concept of central lymph node metastasis intensity.Methods:This study retrospectively analyzed integrated clinic data of 106 cases with PTC undergoing treatment of cervical lymph node dissection in Department of Thyroid and Breast Surgery of the Affiliated Hospital of Inner Mongolia Medical University from Dec. 2009 to Jan. 2014. Based on whether lateral cervical lymph nodes had metastasis, patents were classified into lymph node metastasis positive group ( n=75 cases) , lymph node metastasis negative group ( n=31 cases) . This study explored metastasis-associated risk factors of age, gender, triiodothyronine (T3) , thyroxine (T4) , free triiodothyronine (FT3) , free thyroxine (FT4) , thyroid stimulating hormone (TSH) , thyroglobulin antibody (TGAb) , thyroid peroxidase antibody (TPOAb) , whether combined with Hashimoto’s disease, tumor location, infringing the membrane, mulifocality, tumor glands distribution, tumor diameter, number of central lymph node metastases, central lymph node metastasis ratio, and analyzed the effects of central lymph node metastasis intensity on lateral cervical lymph node metastasis. SPSS 21.0 software was used for data analysis, the metering data of normal distribution was expressed as ± s, and t test was used for comparison between groups. Count data was expressed as a rate (composition ratio) , and comparisons between groups were performed by χ2 test or Fisher exact probability method. Results:Univariate analysis found that whether combined with Hashimoto’s disease ( P=0.087) , tumor location ( P=0.249) , tumor glands distribution ( P=0.219) and tumor diameter ( P=0.224) had no correlation with lateral cervical lymph node metastasis, which showed no statistical significant differences ( P>0.05) . Infringing the membrane ( P=0.030) , mulifocality ( P=0.031) , number of central lymph node metastases ( P=0.022) and central lymph node metastasis ratio ( P=0.001) had correlation with lateral cervical lymph node metastasis, which showed statistical significant differences ( P<0.05) . The number of central lymph node metastases and the increase of central lymph node metastasis ratio had positive correlation with the occurrence of lateral cervical lymph node metastasis; when the number of central lymph node metastases was ≥4 or (and) the central lymph node metastasis ratio was ≥20%, the incidence of lateral cervical lymph node metastases increased significantly, and the difference was statistically significant ( P<0.05) . Conclusion:Infringing the membrane and mulifocality are risk factors for lateral cervical lymph node metastasis. When central lymph node metastasis intensity: number of metastases ≥4 or (and) metastasis ratio ≥20%, lateral cervical lymph node dissection is recommended.
