In view of the imbalance between basic research and clinical research in cancer,and the failure of timely and effective translation from basic achievement to clinical application,new insights to strengthen and accelerate the bidirectional translation between clinical issues and basic achievement have being widely accepted,with the definition of Translational Medicine as a link.With the rapid development of modern molecular biology and cell biology techniques,the strong power of high-throughput deep sequencing,epigenetics,and microenvironment research on exploring cancer biomarkers and interpreting the mechanisms of carcinogenesis and progression,has being taken seriously.Here,we will illuminate the role and further application of deep sequencing,epigenetics,and microenvironment based on analysis from clinical issues or samples in the current cancer research.

This review article briefly described the interaction and inner link between chemotherapy tolerance and metastasis of breast cancer.The common pathways of occurrence of drug resistance and metastasis were analyzed with formation and outcome of breast cancer epithelial-mesenchymal transition (EMT) and with enrichment and function of breast cancer stem cells.The chemotherapy which play positive role in clinical practice was pointed out that may cause negative effects by changing tumor microenvironment.Those evidences show that the theory on tumor microenvironment will help to formulate the research strategies for preventing and reversing resistance of breast cancer to drug and metastasis.

The polymorphism of Bf was determinated in 234 healthy human sera in Beijing by agarose gel high-voltage electrophoresis and PAGIEF followed by immunofixation. The distribution of Bf phenotypes was observed: SS 171, FS 49, FF 8, SS07 4, FS07 1 and SS045 1. Their allele frequencies were, Bf~s = 0.8462, Bf~F=0.1410, Bf~(S07)=0.0107, Bf~(S045)=0.0021. The distribution of Bf phenotypes was good agreement with the Hardy-weinberg law.The time limits of Bf phenotypes in 22 bloodstain samples was determinated.

Objective To investigate the effect evaluation of spironolactone in the treatment of hypertensive heart disease by the real time 3-dimensional echocardiography .Methods Totally 104 patients with hypertensive heart disease were in the study from Jan 2011 to Jan 2012 of our department and divided into objective group and control group .Conventional treatments were put in all the patients and the spironolactone was used in objective group patients only .The results of ventricular morphology and function indexes were compared be -tween the two groups, and then investigate the relationship between cystatin C (CycC) and left ventricular remodeling index (LVRI) at the same time.Results There were significant differences in the comparison of ventricular morphology and function indexes .The left ventric-ular end-diastolic volume(LVEDV), left ventricular end systolic volume (LVESV) and left ventricular ejection fraction (LVEF) of ob-jective group were more advantageous than flowse of control group for prognosis .The same results were observed in the comparison of Cys C and LVRI.Moreover, Cyc C and LVRI had certain correlation in the study .Conclusion The spironolactone can play a positive role in the treatment for the patients with hypertensive heart disease .In the meantime, the RT-3DE is a good evaluation method for the develop-ment of ventricular morphology and function .

106 ethmoidal specimens ranging from 12 to 40 weeks of embryonic age were cut into serial sections and observed by histological method. The results showed that the ethmoid sinus began its development at about 21-23 weeks of fetal life. The frontal folds or furrows were formed by extensions or evaginations of the nasal mucous membrane from the superior and lateral wall of the middle and superior nasal meatuses. The ethmoid cells appeared at 24-26 weeks and they kept their own small ostia that opened into the middle and superior nasal meatuses. The number and size of the ethmoid cells were increased with the age. The cell cavities showed balanced enlargement. At birth each ethmoid labyrinth had 6-11 cells, measuring on the average 1.7?1.3?2.0 mm~3 in size. The distribution of the ethmoid cells approached those of mature age. The epithelium of the ethmoid sinus was cuboidal or low columnar in shape. Cilia appeared sparse. Tunica propria, mainly composed of the connective tissue and its stroma, was thick, loose, and less vascular and glandular. It suggested that the ethmoid sinus was one of the accessory nasal sinuse that developed first. The ethmoid sinus presented at birth and its appreance were not synchronous, but their location were relatively invariable. The histological structure of the mucous membrane in the ethmoid sinus was somewhat different from those of the nasal mucous membrane. It showed that the development of the ethmoid mucous membrane was still imperfect in the newborn.

Objective To detect the expression of HER2 and TOPOⅡ? in human breast cancer to explore the relationship between them and the potential value in the chemotherapy of breast cancer. Method 24 breast cancer tissues and paired normal tissues were investigated. RT-PCR and imumohistochemical staining were used to detect the expressions of HER2 and TOPOⅡ? at the transcription and protein level respectively. Results HER2 mRNA expressed positively in 29% (7/24) breast cancer tissues vs 4% (1/24) in paired normal tissues. The positive expression of TOPOⅡ? mRNA in breast cancer tissues and paired normal tissues were 92% (22/24) and 21%(5/24) respectively. The result of the immunohistochemical staining showed that the positive rates of HER2 and TOPOⅡ? in breast cancer tissues were 30%(6/20) and 94%(16/17) respectively, which was consistent with RT-PCR. The 6 cancer samples with HER2 positive expression coexpressed TOPOⅡ?. The expression of these two proteins was correlated(R=0.524,P

Objective To evaluate the safety of cardiac rehabilitation(CR)for the elderly patients with chronic heart failure(CHF). Methods All 72 patients with CHF over the age of 60 were enrolled and randomly divided into two groups: the experimental groups(n=35)and control groups(n=37). Patients in both groups were treated strictly according to the treatment guideline. On the basis of drug treatment,patients in experimental group were given a comprehensive CR program. The occurrence of all-cause death,due to deterioration of heart failure readmission and serious adverse events were compared after 12 months. ResultsCompared with the control group,the incidence of all-cause and the cases for the deterioration of heart failure readmission decreased in the experimental group after 12 months(P < 0.05). There was no statistically significant difference in the occurrence of serious adverse events between the two groups(P > 0.05). Conclusion For the elderly CHF patients,cardiac rehabilitation can effectively reduce all-cause death and deterioration of heart failure readmission in patients,but the serious adverse events had no obvious change. It is safe and effective for the elderly patients with chronic heart failure.

] Objective To explore the role and mechanisms of FGF2 in chemo?resistance in breast cancer. Methods The inhibitors for different signal pathway were used to treat two drug?resistant breast cancer cell lines MCF?7/5?Fu and T47D/5?Fu established in our lab. MTS assay was used to determine chemo?sensitivity and Hoechst stain was used to measure apoptosis. Protein activation and FGF2 protein level in cell culture medium were detected by western blot and ELISA respectively. Results Akt inhibitor MK?2206 (20 nM) and mTOR inhibitor AZD8055 (2 nM) significantly reversed the chemo?resistance of MCF?7/5?Fu and T47D/5?Fu cell lines to 5?Fu and paclitaxel, but ERK1/2 inhibitor SCH772984 showed no significant effect. Compared to parent cell lines MCF?7 and T47D, p?Akt and p?S6K (represented as mTORactivity) levels were obviously up?regulated in MCF?7/5?Fu and T47D/5?Fu cell lines, and so do the FGF2 mRNA level and FGF2 protein level from culture medium. Moreover, FGFR inhibitor AZD4547 (4 nM) markedly reversed the chemo?resistance of MCF?7/5?Fu and T47D/5?Fu cell lines to 5?Fu and paclitaxel and down?regulated activation of FGFR?Akt?mTOR signal pathway. In agreement, FGF2 protein (10ng/ml) enhanced the chemo?resistance of MCF?7 and T47D cell lines to 5?Fu and paclitaxel and up?regulated activation of FGFR?Akt?mTOR signal pathway. Conclusion Activation of FGF2?FGFR?Akt?mTOR signal pathway promoted chemo?resistance of breast cancer cells.

Objective To introduce the initial experience of transperitoneal laparoscopic uretero ureter anastomosis for ureteral obstruction. Methods This series included 9 cases (4 males and 5 females).Their mean age was 49 years (range,34-64 years).Five cases had obstruction on the left side and 4,on the right.Of the 9 cases,2 had upper segment ureterolithiasis with big polyps;1,retro venacaval ureter;1,upper segment ureter polyps;1,middle segment ureter tumor;1,middle segment ureter stricture;1,upper segment ureter stricture after open ureterolithotomy;1,middle segment ureterolithiasis with stricture;1,lower segment ureter ligation after hystero myomectomy.All the 9 cases underwent relief of ureter obstruction and uretero ureter anastomosis via laparoscope. Results The operations were all successful in 9 cases.The blood loss was 80-200 ml (mean,147 ml).No one needed blood transfusion.The operative time was 80-170 min (mean,116 men).Postoperative drain had no obvious leakage of urine.Double J tubes were removed 1 month after operation.The mean follow up was 14 months.IVU,BUS or RGU examinations showed that hydronephrosis was lessened and renal function was improved. No ureter stricture was found.One patient with ureter tumor was pathologically confirmed to suffer from ureter squamous carcinoma; the edge was negative.However,the patient developed recurrence 13 months after operation and then underwent renal fistulization again. Conclusions Laparoscopic uretero ureter anastomosis is an effective and minimally invasive method and can be used as an alternative approach to treatment of ureter obstruction.
