Objective To summarize the cytological features of breast carcinoma by fine needle aspiration and differential diagonsis of breast hyperplasia and breast flbroadenoma. Methods Cytological features about 175 cases of breast cancer were analyzed,contrasted with 76 cases of breast hyperplasia and 93 eases of fibroadenoma. And 20 cases of low-diagnosis breast cancer were analyzed, compared with 13 cases of excessive diagnosis. Results The followings were found:disorderly arranged cells in 169 cases of breast cancer, about 96.9% in 175 cases,loose distance between the nucleus in 125 cases of all cases (about 71.4%). The percentage of small groups or scattered cells, medium size cells, round nucleus and irregular border nucleus was 34.3% (60/175) ,81.1% (142/175), 88.6% (155/175) and 28.6% (50/175) respectively. The nucleus/cytoplasm ratio was increased in 105 cases of all (about 60%). The nucleus/cytoplasm ratio was obviously reduced in 15 cases of all (about 8.6%). Big nucleolis were observed in 49 cases of all (about 28%). There was significant difference between nucleus size in 136 cases of all (about 77.7%). There was not myoepithelial cell in 168 cases of all (about 96%). The percentage of visible necrosis, scsttered round nucleus and integrity of cytoplasmic was 13.7% (24/175) ,89.7% (157/175), 66.9% (117/175) respectively. The cases of all above features were significantly more than those of breast hyperplasia and breast fibroadenoma (P <0.05). The percentage of large number of cells was 52.6% in 175 breast cancer cases,higher than 5.3% in 76 breast hyperplasia cases. There was a significant difference(P <0.05) between two groups. In 20 cases of low-diagnosis breast cancer the percentage of round nucleus with integrity of cytoplasmic, special arrangement cells was 70% (14 cases) ,35% (7 cases) ,higher than the cases in 13 excessive diagnosis cases. There was a significant difference(P < 0.05) between two groups. Conclusion The cell morphological characteristics of breast caner by fine needle aspiration are large number of cells, loose distance between the nucleus, disorderly arranged cells, small guoups or scattered cells, integrity of cytoplasmic, increased nuclear, round nuclear, irregular border nucleus,increased or decreased nucleus/cytoplasm ratio, big nucleoli, significant difference in nuclear size, no myoepithelial cell, visible necrosis. Most of breast cancer can be distinguished from breast hyperplasia and breast fibroadenoma by above characteristics. All those cytological characteristics are helpful to identify difficult case.

It also provided powerful convictable effects on the accuracy and scientificity of acupuncture and moxibustion clinical practice, which gained well-acceptance from patients. In the treatment of certain diseases, acupuncture and moxibustion have become irreplaceable so that acupuncture and moxibustion can be strongly promoted both at home and abroad. There were some common problems occurred during the establishment of the national standardization onStandardized Manipulations of Oral and Lip Acupuncture. This article reviewed, analyzed and discussed questions occurred during the standardization establishment. The results showed that according to the principle of standardized production, a rigorous, scientific and reasonable text standard can be established. Advices or opinions gained during the process can be used as references for future standardization establishment. It was concluded that the standardization of acupuncture had great guidance in the acupuncture clinical application. It is an arduous and long-term mission to achieve and strengthen the position of international standardization of acupuncture and moxibustion. The government should increase the effort on investment and promotion of acupuncture and moxibustion standardization. Conversation and cooperation should also be strengthened with international communities to promote the standardization implementation.

L9 (3(4)) orthogonal experiment was used to design the extraction technology of compound Clematidis Radix spray. Weight coefficients of active ingredients and dry extract rate were solved by information entropy. Support vector machine (SVM) was established and the model parameters were optimized through the genetic algorithm. Grid search algorithm was used for optimization of extraction technology of Clematidis Radix spray. The optimal extraction technology was to extract Clematidis Radix spray in water with 6 times the weight of herbal medicine for 3 times, with 2 h once. Bias of value between real and predicted by SVM was 1.23%. SVM was compared with traditional intuitive analysis of orthogonal design. It indicates that the new method used to optimize the extraction parameters of compound Clematidis Radix spray is more accurate and reliable.

Objective To establish a mouse model of prostate cancer expressing human PSCA for the development of new anti-tumor drugs or vaccines. Methods The total RNA of DU145 cells,a human prostate cancer cell line,was isolated by using TRIzol reagent according to the (RT-PCR),the first-strand cDNA was synthesized using the SuperScript First-Strand synthesis system. The human PSCA gene was amplified with the primers and cloned into the plasmid pcDNA3.1 to generate pcDNA-PSCA. DNA sequencing was used to confirm the constructs. The mouse prostate tumor cell line RM-1 cells,syngeneic to C57BL/6,were transfected with pcDNA-PSCA plasmids followed by selection using G418. RT-PCR analysis was performed to examine the validity of the constructs. Expression of PSCA on the cell surface was determined by staining with anti-PSCA antibody,and the anti-PSCA antibody was detected using an FITC-conjugated goat anti-rabbit IgG antibody,and analyzed by flow cytometry. 4-6-week-old male C57BL/6 mice purchased from the Laboratory Animals Center were inoculated with different amounts of RM-PSCA cells to search for suitable cell population which can form tumor in mouse,and the mice were monitored twice a week. The growth and the survival time of mice were measured,respectively. The tumor volume was measured by vernier caliper according to the formula:V=0.5a×b~2,where a and b are the long and short diameters of the tumor,respectively. Results The plasmid pcDNA-PSCA was successfully constructed and the PSCA was successfully expressed in RM-PSCA 7~# and RM-PSCA 28~# cells by RT-PCR and confirmed by flow cytometry. 1×10~5 RM-PSCA cells were sufficient to get tumor growth in 100% of inoculated mice. The tumor grew quickly and the volume of the tumor reached 12000 mm~3 within 34 days. All the mice died within 40 days and their mean survival time was 37 days. Conclusion A PSCA-expressing tumor model in mice has been successfully established. It can be used to evaluate the activities of drugs or vaccines.

Objective:To construct CD106-targeted RNAi lentiviral vector plasmids. Methods:4 targets aimed at CD106(Target 1, 2, 3, 4)were designed. Oligo-DNA fragment containing short hairpin frame was synthesized and reannealed, and then cloned into lentivi-ral expression vector. PCR and sequencing analysis were made for verifying the positive clones. The virus packaging plasmids were trans-fected into 293T cells to harvest siRNA lentivirus. After infection in HN12 cells, Real-time PCR and western blot were performed to de-termine the expressing level of CD106. Results:PCR and sequencing revealed that siRNA plasmids was correctly constructed. Virus with a titer of 1 × 109 TU/ml was successfully packaged at least. CD106 expression in HN12 cells could be knockdown by virus infection sig-nifically, compared with negative control lentivirus. Conclusion: The recombinant lentiviral siRNA expressing vector targeting human CD106 gene has been successfully constructed and packaged. CD106 gene in cells may be down-regulated by lentiviral siRNA.

Objective To investigate the protective effects of atorvastatin on hyperphosphate-induced rat vascular smooth muscle ceils (RVSMCs) calcification and to discuss the mechanism. Methods RVSMCs were placed in various culture media, including normal phosphate medium, high phosphate medium, ZVAD-FMK medium and atorvastatin medium.Calcium content and cell protein content were quantified by the o-cresolphthalein complexone method and BCA protein assay respectively. Calcification was visualized by yon Kossa staining. And cell apoptosis was quantified by ELISA. Results (1)At day 3, 6, 9, RVSMCs calcification occurred more frequently in high phosphate medium than that in normal phosphate medium (P<0.05). (2)At day 6, RVSMCs calcification was significantly inhibited in 1.0 μmol/L and 2.0 μmol/LZVAD-FMK medium (P<0.05). And in 10 nmol/L and I00 nmol/L statin medium, RVSMCscalcium deposition significantly decreased (P<0.05). (3)RVSMCs apoptosis and calcification occurredfrequently in high phosphate medium. And atorvastatin significantly inhibited RVSMCs apoptosisboth in long-term and short-term (P<0.05). Conclusions Hyperphosphate can induce the calcium deposition of RVSMCs in vitro. Atorvastatin protects RVSMCs from phosphate-induced calcification by inhibiting apoptosis.
