Objective:To study the effect ofRNA interferenc(RNA)ion FAK gene expression and the biological characteristics of human breast cancer MCF-7.Methods:The constructed recombinant plasmid FAK-siRNA was transfected into human breast cancer MCF-7 cell using LipofectamineTM 2000.The transfection efficiency was observed under fluorescence confocal microscope.Expression of FAK mRNA and protein were detected by reverse transcription polymerase chain reaction(RT-PCR)and Western blot.Distribution of cell cycle was assessed by flow cytometry.Cell penetrate matrigel capacity were determined by invitro experiment.Results:FAK-siRNA effectively inhibited FAK mRNA and protein expression(P

Developing along with the chemicals to tend gradually hard and adopting the natural medicine to rise,the international pharmacy field interesting in Chinese materia medica(CMM) increases gradually.The exterior competition of the CMM enterprises is becoming drastic and the secondary deve-(lopment) of CMM for the medicine enterprises in our country should be a better choose to face the international medicine market competition.The internal and external process about the secondary development of CMM should be taken into account and the strategy that should be adopted in the secondary development put forward.Such as: secendary development of new medicine of the CMM compound recipe;turning deeply to the CMM foundation research;the importance of developing the safe and valid CMM whose qua-(lity) is stabile and controlled;the importance of rising the processing level of the product,etc.It emphasized the importance in appling modern science and technology in the text.

Objective To study the curative effectiveness of external iliac-popliteal artery artificial graft cross bypass in treating extensive arterial occlusion in unilateral lilac-femoral arteriosclerosis. Methods From Sep. 1999 to Oct. 2007, 39 elder patients were diagnosed as having extensive arterial occlusion in unilateral lilac-femoral arteriosclerosis by color Doppler ultrasonography, CTA or DSA. 25 patients (61.5%) had resting pain, 14 had ulcers or gangrenes in the toes. The average ankle-brachial index was 0. 19. Contralateral external iliac-popliteal artery artificial graft cross bypass surgeries were performed on 22 patients from left to right, the other 17 were from right to left. Results There were no perioperative death or amputation. The ankle-brachial index increased from 0 ～ 0. 41 ( preoperative ) to 0. 85 ～ 1.02(postoperative) ; the claudication distance increased from 15 ～ 60 m (preoperative) to 350 ～ 500 m or more than 500 m [ postoperatively at the speed of (100 ～ 120) m/min] ; The postoperative color Doppler uhrasonography showed the average velocity of the popliteal artery was 45 cm/s. In the anterior tibial artery or the posterior tibial artery, little blood flow was showed in preoperative color Doppler ultrasonography examination, the postoperative average blood flow velocity was 41 cm/s. 35 patients (89. 7% ) were followed up for an average of 3.4 years, with an accumulative patency rate of 85.7%. Four patients had amputation, the limb salvage rate is 88.6%. Conclusion External iliac-popliteal artery artificial graft cross bypass is effective in treating unilateral lilac-femoral arterial occlusion, particularly for aged patients with vital organ incompetence.

Papillary carcinoma is one of the commonest tumors in the thyroid.The pathologic diagnosis of papillary carcinoma as well as follicular carcinoma and follicular adenoma of the thyroid are based on the morphology observation hitherto.However,the diagnostic value of immunostaining for distinction among differentiated neoplasm of the thyroid was so far absent.With the identification of the special markers of lymphatic vessel endothelial cell by immunohistochemical method in the recent years,the rapid progress in the research of lymphangiogenesis of the tumors had been made.This article briefly reviewed the progress of the special markers of lymphatic vessel endothelial cell and vascular endothelial growth factors in the differentiated neoplasm of the thyroid.

Objective To investigate the correlation between the expression of p170、GST-π 、TOPO Ⅱ and the expression of Her-2 in human breast cancer. Methods The expression of Her-2 was detected by fluorescence in situ hybridization.The expression of p170,GST-π,TOPO Ⅱ were tested in 48 breast cancer by immunohistochemical SP method,and their correlations with clinicopathological features and the expression of Her-2 were analyzed.Results The positive rate of p170,GST-π,TOPO Ⅱ were 43.8 ％(21/48),39.6 ％(19/48),56.3 ％(27/48),respectively. The expression of p170, GST-π,TOPO Ⅱ positively correlated with the expression of Her-2(P＜ 0.05).The levels of p170,GST-π,TOPO Ⅱ expression were not associated with age,primary tumor and lymph node metastasis(P ＞ 0.05).Conclusion There is great possibility of chemotherapy drug resistance in breast cancer with expression of Her-2.Expressions of p170,GST-π,TOPO Ⅱ and Her-2 have an instructive significance for chemotherapy.

Sinusoid lining endothelial cell(SEC) of the liver is a group of cells different from vessel lining endothelial cells with high heterogeneity characteristics, it shows many biological functions in normal liver and plays a role in liver injury caused by acute and chronic liver diseases as well as fibrogenesis. Increasing attention has been paid to the capillarization in hepatocellular carcinoma in recently years, some studies showed that SEC is attributed to the formation of capillarization with changes of the immunophenotype, such as expression of CD34.The pathological study of SEC on liver disease was briefly reviewed in this paper.

Although dyslipidemia is common in the patients with end-stage renal disease undergoing dialysis, it is still controver-sial in the efficacy and safety of lipid-modulating agents used in the patients. In this paper, current large-scale randomized controlled trials and observational studies were reviewed, and the influence and characteristics of dyslipidemia as well as the application of com-mon lipid-modulating agents in dialysis patients were summarized. The current clinical evidence suggested that the use of statins with or without ezetimibe could effectively reduce the level of blood lipid in dialysis patients without increased risk of adverse events, while it had limited role in cardiovascular protection;fibrates had higher risks in dialysis patients; nicotinic acids had limited use mainly be-cause of their unbearable side effects.

Immune thrombocytopenia (ITP) of childhood is the most common hemorrhagic disease which is characterized by isolated thrombocytopenia.Depending on individual patient characteristics,appropriate initial management for newly diagnosed ITP may be either watchful waiting or pharmacologic intervention.The main options for initial pharmacologic intervention include a single dose of intravenous immune globulin(IVIG) and/or a short course of glucocorticoids.For ITP children with severe or life-threatening bleeding,it is recommended that both platelet transfusions and the combination of pharmacotherapy.Approximately 20 percent of children who present with ITP will progress to chronic ITP(CITP).Children who develop CITP should have an additional evaluation to exclude other disorders.The pharmacologic options for CITP include Rituximab,and thrombopoietin (TPO)/TPO receptor agonist (Romiplostim or Eltrombopag).Combination therapy and novel immunological targeting drugs become more effective treatment options.Splenectomy is only suit for a small number of children with chronic refractory ITP patients who present significant and persistent hemorrhagic symptoms requiring repeated pharmacologic interventions.
