Background and purpose:Gemcitabine-based chemotherapy has been shown to have signiifcant activity and favourable safety in metastatic breast cancer patients, but the effectiveness is limited due to drug resistance. MicroRNAs are a family of small non-coding RNA molecules, acting as oncogenes or tumor suppressors. Although various mechanisms of chemoresistance have been uncovered, the aberrant microRNA expression and its relationship with drug resistance of breast cancer are still unclear. This study explored the potential role and underlying mechanism of microRNA-21 in gemcitabine resistant breast cancer. Methods:MDA-MB-231 cells were continuously exposed to the increasing concentrations of gemcitabine to induce drug resistance to gemcitabine, which was 10 times more resis-tant. Then multiple methods were used including real-time PCR (RT-PCR), CCK-8, Western blot, transfection, wound healing and Transwell assay to observe the effect of microRNA-21 on epithelial-mesenchymal transition (EMT) and chemosensitivity. Results:The expression of microRNA-21 was up-regulated in gemcitabine resistant breast cancer cell line and inversely correlated with gemcitabine sensitivity. Manipulation of microRNA-21 status could change microR-NA-21 level, and could result in corresponding changes in EMT status and drug sensitivity. Conclusion:MicroRNA-21 induces gemcitabine resistance possibly via EMT process in breast cancer.

OBJECTIVE To observe the bacterial content on the suspension bed sheet in burns intensive care unit.METHODS To detect the bacterial content on the suspension bed sheet and the common sickbed sheet(20 sheets in each group) after sampling them before use and 12 and 24 hours after use and to compare them.RESULTS The bacterial content on two sorts of the sheets before use was accorded with the Ministry of Health standards.but 12 hours after use the significant bacterial content on the common sickbed sheet [(4.9?2.1) CFU/cm2] was much higher than that on the suspension bed [(3.2?1.1) CFU/cm2,P0.01].CONCLUSIONS Using suspension bed could reduce bacterial content on the sheet and ease nurse workload.

Background and purpose:The third generation of aromatase inhibitors (AI) in postmenopausal hormone receptor-positive patients is the routine treatments in endocrine therapy. The 500 mg fulvestrant showed clini-cal beneifts in patients with previous AI treatment. This study aimed to access the effcacy and safety of 500 mg fulves-trant in estrogen receptor (ER) positive postmenopausal patients who had previous AI treatments with locally advanced and metastatic breast cancer.Methods:This study retrospectively analyzed the clinical data from 188 post-AI ER positive and (or) progesterone receptor (PR)-positive locally advanced and metastatic breast cancer patients treated with 500 mg fulvestrant in Fudan University Shanghai Cancer Center from Jul. 2011 to Dec. 2015. Primary end point was progression-free survival (PFS). Secondary end points were objective response rate (ORR), clinical beneift rate (CBR) and safety proifle.Results:After the median follow-up of 11.3 months, median PFS was 5.9 months (95%CI: 4.2-7.5), CBR was 40.0% and ORR was 3.4%. COX proportional hazards regression analysis indicated that PFS was correlated with the number of metastatic sites (HR=1.92, 95% CI: 1.2-2.9,P =0.002) and previous lines of chemotherapy (HR=1.52, 95%CI:1.0-2.1,P=0.022). Six patients stopped the treatment for intolerable adverse events.Conclusion:The treatment of 500 mg fulvestrant has a favorable effcacy and safety in treatment of post-AI ER positive postmenopausal patientswith metastatic breast cancer.

Objective To observe ultramicro pathologic change of rabbit brain central damaged tissue and peripheral tissue after LOT, to evaluate the changed structure of blood brain barrier (BBB) of peripheral tissue in acute stage. Method Seventy Newzealand rabbits were randomly screened from Zhejiang University Animal Experiment Center. By stereotaxic technique, semiconductor surgica laser fibers were inserted into right frontal lobes and heat treated to randomly build LITT Group A (2 W, 600 s, n = 20) and LITT Group B (15 W, 100 s, n = 20) brain damaged models successfully. Other 15 nomal rabbits were randomly distributed as mannitol perfusion group and fake operation group. The ultramicro structures in central thermodamaged tissue were observed with transmission electro microscope after LITT 3 h,6 h,12 h,24 h. In peripheral tissue, ultramicro morphologic changes of brain vessels and BBB were evaluated. S100B protein in serum and BBB indexe were measured at different stages post LITT. Experimental data were treated as one-factor analysis of variance and q test. Results The brain damage center connected the tip of laser fiber and turn into thermodamage tissue. The main structure changes were cytoclasis, damnification of cell membrum, swelling of cell organelle such as mitochondrion, endoplasmic reticulurn,disappearance of mitochondrion and sparseness of cytoplasm in local tissure. Heat energy conducted to damage peripheral tissue, some cells occured apoptosis in different stage. In acute stage after LITT, contracted capillary vessel, oncreted red cell, swell endothelium cell, broken base membrum, wide around clearance and destroyed aperture structure were identified. The levels of serum S100B and BBB indexe dramatically rised. The opening time of BBB in peripheral tissue was longer than mannital perfusion group. However at 24 h post LITT, they began to recover in Group A. The difference of serum S100B and BBB indexe between Group A and Group B has statistical significance ( P =0.0087). Conclusions With semiconductor laser heat treatment and stereotaxic techniqe, definite cells cytoclasis, cell membrance structures and chondriosome damage could be performed obviously in rabbit brain thermotherapy point. Apoptosis could be found in peripheral tissue, BBB could be opened in an acute stage. The opening time course of BBB was shortened in those LITT cases with small power. It shew us a new method to perform a safe and exact damage zone of brain for functional neurosurgery.
