Objective To study the association among the color Doppler flow pattern, vascular distribution and the lymph nodes metastasis in breast carcinomas. Methods Sixty-eight patients with infiltrating mammary gland duct carcinoma were divided into the no-lymph-nodes-metastasis group (group I , 37 cases) and the lymph-nodes-metastasis group (group Ⅱ , 31 cases), group Ⅱ were subdivided into group Ⅱa (19 cases): lateral lymph nodes positive of pectoralis minor and group Ⅱ b (12 cases): rear of pectoralis minor and subclavian lymph node positive. Blood flow parameters [peak systoltc velocity (PSV),resistent index ( RI)] and vascular Alder grades were observed and measured with color Doppler ultrasound.The results were compared with the incidence of lymph node metastasis. Results PSV and RI were not significantly different between group Ⅰ and group Ⅱ (t = -0.19,-0.63,P＞ 0.05),and also between group Ⅱ a and group Ⅱ b (t =-1.12,-013,P ＞0.05). By using vascular Alder grades,there were no significant differences between group Ⅰ and group Ⅱ (x2= 0.46, P＞ 0.05 ), but the significant differences were observed between group Ⅱ a [10.5%(2/19) ,63.2%( 12/19) ,26.3%(5/19) in Alder Ⅰ , Ⅱ , Ⅲ grade] and group Ⅱ b [8.3%( 1/12), 16.7%(2/12),75.0%(9/12)in Alder Ⅰ , Ⅱ ,Ⅲ grade](x2 = 7.41,P＜0.05). Conclusion The pattern of blood flow has no correlation with lymph nodes metastasis, vascular Alder grades of carcinoma shows some relevance with the lymph nodes metastasis in the patients with infiltrating mammary gland duct carcinoma.

AIM:To improve the standard of quality control of Yiqi Zhixue Granule(Radix Codonopsis,Radix Astragali,Rhizoma Atractylodis macrocephalae,etc.) METHODS: In the prescription,both Radix codonopsis and Radix Astragali were identified by HPLC.Folium mahoniae was distinguished by TLC.Rhizoma Bletillae was authenticated by microscope.Morever,RP-HPLC method was adopted to determine the astragaloside content in the productions,using a column of C_(18),the column temperature was at 35(?C),acetonitrile-water(32∶68) as a mobile phase,he flow rate was 1.0 mL/min,and ELSD as detection in which the tube temperature was set at 102(?C) and the air flow was at 2.8 mL/min,the impactor was chosen off. RESULTS: The established identification methods were simple and proper,reflecting a good specificity,while the determination method was accurate and reliable,which showed the recovery of 97.95%,RSD=2.21%(n=9),the intermediate precision of RSD=2.67%(n=3),the robustness of RSD=3.67%(n=3) between columns,and the LOQ of 0.539 2 ?g,RSD=2.92%(n=5). CONCLUSION: The improved standard of quality control of Yiqi Zhixue Granule is not only practical but capable of effectively controlling the quality of the medicine as well.

Epithelial-mesenchymal transition (EMT) is an important biological process in embryonic development and tumori-genesis. In this process, epithelial tumor cells can obtain mesenchymal phenotypes and promote tumor invasion and metastasis. EMT is controlled by multiple transcription factors, signal pathways, and microRNAs. EMT and cancer stem cells are closely related. EMT also promotes the self-renewal ability of tumor cells and the overexpression of EMT-related markers in tumor cells with stemness. Some mi-croRNAs can control EMT process and stemness. In this study, recent developments on EMT and cancer stem cells in tumor metastasis were summarized to provide new insights into target therapy of tumor metastasis and recurrence.

Objective To investigate the clinical outcomes of minimally invasive treatment of elderly patients with osteoporotic and stable intertrochanteric fracture with percutaneous compression plate as compared with sliding hip screw.Methods Retrospec-tive analysed 86 old patients with stable intertrochanteric fracture treated by PCCP(PCCP group)or SHS(SHS group)from Janu-ary 2009 to December 2010.There was 39 cases in the PCCP group and 47 cases in the SHS group.The operation time,blood loss, transfusion rate,incidence of lateral wall rupture,full weight bearing time and last Harris hip scores were recorded and compared between two groups.Results Shorter operation time,less blood loss and high Harris scores were observed in the PCCP group(P<0.05),but no signifocont difference between the two groups of tromsfusion rate and incidence of Lateral wall rapture(P>0.05). Conclusion compared with SHS,PCCP can lead to a lower surgery blood loss,shorter operation time and a better hip function.It is a suitable impant for elderly patients with osteoporotic and stable intertrochanteric fracture.

The corneal refractive surgery is invented and improved constantly from 1970's till now,and the excimer laser corneal refractive surgery is the important method for correcting myopia.The corneal safety of post-operation long time is the key point and always is worried by surgeon due to the surgical procedure directly on the normal corneal tissue by different types of flap and ablation. From the corneal safety of view,the advantages and disadvantages of different corneal refractive surgeries were compared and the indications for different methods were mentioned in order to provide rational clinical data.

The physical change of astigmatism in human eye is analyzed in this article.Different methods for astigmatism applied in clinic are expound and compared with advantages and disadvantages.It is important that analyzing carefully and designing customized normgram for astigmatism eye to approach the perfect visual function after reasonable treatment.

The recent report "The Consensus Coding Sequences of Human Breast and Colorectal Cancers"published in Science represents the first unbiased systematic mutational analysis of human genome at any disease states after the completion of The Human Genome Project. It was tentatively discussed how to take advantage of the candidate cancer genes found in this study in discovery of novel targets of therapeutic drugs. In addition, the penitential values of the candidate cancer genes in identification of patients at high risk of cancer, and in renewing classification of tumors based on underlying molecular mechanisms are introduced.

Objective: To study the cellular immune responses and the anti-tumor effects induced by peptides derived from onco-protein HER2/neu. Methods: Two HER2/neu peptides compatible with H-2Kd binding motif as tumor rejection antigens were synthesized. The ability of inducing peptide-specific CTLs and suppressing the tumor growth in BALB/c mice immunized by HER2/neu peptide was analyzed. Results: HER2/neu peptides could promote the proliferation of BALB/c lymphocytes both in vitro and in vivo. HER2/neu peptide-specific CTLs could be induced from peptide-immu-nized BALB/c mice, which showed specifically killing effects on HER2/neu positive SP2/OHER2 cells but not on HER2/neu negative SP2/O cells. Moreover, the growth of SP2/OHER2 tumor were significantly suppressed in BALB/c mice immunized with HER2/neu peptides. Conclusion: These results suggested that it was feasible to use MHC-I epitopes derived from tumor-specific antigens as vaccines for cancer immunotherapy.
