Multidrug resistance (MDR) is a major impediment to the success of cancer chemotherapy. Multidrug resistance-associated proteins (MRPs) play an important role in the process of MDR. As an ATP-binding cassette (ABC) transporter superfamily, MRPs are selective and specific drug efflux pumps. In this paper, physiological characteristics, structural characteristics and resistance profile of MRPs and the associated reversal studies are reviewed.

In recent years, with the development of some new techniques based on bronchoscopic skills, such as endobronchial ultrasonography, autofluorescence bronchoscopy, electromagnetic navigation bronchoscopy, fibered confocal fluorescence microendoscopy and optic coherence tomography of the advent of technology, which solved the shortcomings of traditional technology from different areas and dimensions. Although these techniques need to be improved and clinical verified further, it was believed that the great impact on diagnosis and treatment of lung cancer should be made by them.

Objective To observe the effect of nimodipine on the treatment of hypertensive cerebral hemorrhage(HCT) .Method Patients with HCT in 24 hours were randomLy divided into control group and treatment group.The treatment group was given 50mL(10mg) nimodipine injection for 14 days and then was orally given 40 mg nimodipine for another 14 days.The control group was given all treatment drug except nimodipine.The absorption of hemorrhage and edema,CSS and BI were observed and compared between the two groups.Result The hemorrhage and edema were better absorbed in the treatment group(t=2.14,P

OBJECTIVE: To investigate the efficacy of endoscopic sinus surgery (ESS)-based multidisciplinary therapy for patients with chronic rhinosinusitis (CRS), nasal polyps and bronchial asthma. METHOD: The study included 32 patients with CRS, nasal polyps and bronchial asthma who received ESS, besides surgery, who also used glucocorticoid inhalation, nasal spray and nasal irrigation perioperatively. The evaluation of the treatment was performed 3 years post after ESS. RESULT: In the 32 cases treated with ESS, 19 cases were cured, 9 cases were improved, 4 cases were inefficient by the treatment. The cure rate was 87.5%. The asthma symptoms were improved in 9 patients (P < 0.01), compared to 2 before surgery. The numbers of patients with improved symptoms were increased from 2 before the surgery to 9 after the surgery. CONCLUSION As the main treatment, endoscopic si- nus surgery was effective on CRS with asthma.

Studies have shown that most of the sequence in the mammalian genome is transcribed into long noncoding RNAs (lncRNAs). Their crucial roles in gene regulation are becoming a hotspot in current biomedical research. LncRNAs can control gene activities through multiple mechanisms such as: 1) direct or indirect regulation of gene expression via cis-/trans-action or function as protein baits in the nucleus; 2) affecting the stability and the translational process of mRNA; 3) functioning as competitors to regulation of microRNA; 4) binding to transcription factors. Recent studies have highlighted the significance of lncRNAs in development and diseases, and their potentials in future clinical application.

Objective To investigate effect of pidotimod on TH1/TH2 balance and immune factor in patients with severe trauma.Methods 90 cases with severe chest trauma patients were randomly divided into two groups.45 cases in control group were treated by conventional anti-inflammatory treatment, 45 cases in experimental group on base of control group with pidotimod 800mg /times, 1 times daily.After treatment, the serum levels of IL-4, IFN-γ, IL-2, IL-10, IL-17,IgM, IgA and IgG were compared.Results Compared with before treatment, indexes were improved(P<0.05). Compared with the control group, IL-4 level was lower, IFN-γlevel was higher, IFN-γ/IL-4 was higher(P<0.05).IL-2, IL-10, IL-17 level was higher(P<0.05).IgA, IgM, IgG level was higher(P<0.05).Conclusion Pidotimod can balance the TH1/TH2 in the patients with severe trauma, and adjust the serum levels of IgM, IgA and IgG,can be used in clinical application.

Objective: To explore the influence of resveratrol (Res) on the growth of Lewis lung carcinomas in mice and the corresponding mechanism. Methods: The Lewis lung carcinoma model was established in C57BL mice. Forty C57BL mice were randomly divided into 4 groups (n = 10): control group, low-dose Res group (2.5 mg · kg-1 · d-1), middle-dose Res group (5 mg · kg-1 · d-1) and high-dose Res group (10 mg · kg-1 · d-1). Mice were given intragastrically with Res for 20 d. All mice were sacrificed on d 22 after inoculation. The volume and weight of tumors were recorded. Microvessel density (MVD) in tumor tissues was measured by immunohistochemistry. The expression level of vascular endothelial growth factor (VEGF) was examined by immunohistochemistry and RT-PCR. The apoptotic index (AI) was determined by TUNEL assay. Results: The tumor growth was suppressed significantly in Res 5 mg and 10 mg · kg-1 · d-1 groups. The weights and volumes of Lewis lung carcinoma in both groups above were markedly decreased compared with control group (P < 0.01). The inhibitory rates were 39.04% and 49.66%, respectively, which was significantly higher than that in Res 2.5 mg · kg-1 · d-1 group (12. 33%, P < 0. 01). Mice in Res 5 mg and 10 mg · kg-1 · d-1 group had markedly lower levels of VEGF expression and MVD and significantly higher AI compared with control group (P < 0.01). However, Res 2.5 mg · kg-1 · d-1 had no obvious influence on VEGF expression, MVD and AI (P > 0.05). Conclusion: Res remarkably inhibites the growth of Lewis lung carcinoma in mice by inhibiting expression of VEGF, reducing MVD, and promoting apoptosis.

Objective To explore the surgery methods for multiple fibroadenoma of breast,provide a ref erence for the surgical treatment of breast multiple fibroadenoma.Methods The clinical data of 152 cases of breast multiple fibmadenoma admitted from January 2008 to October 2012 in Department of Breast Surgery,Obstetrics and Gynecology Hospital of Fudan University were analyzed retrospectively.All the cases were applied intraoperative B-ultrasound guided,taken the areola incision through breast subcutaneous layer approach for resection of multiple breast fibroadenoma.The surgical incision design,surgical procedures and results of operations were analyzed.Results All 152 cases fibroadenoma were resected which were guided by B-ultrasound with areola incision.One month and three months after operation,the assessment of physician-patient for the scars were different.There was no significance in the Pearson Correlations which were 0.894 (P =0.106) and 0.905 (P =0.065),respectively.But twelve months later,it satisfied with the appearance of scar,either the patients or the doctors (P ＜ 0.05).The Pearson Correlation was 0.946 (P ＜0.001).Conclusions B-ultrasound guided areola incision through the breast subcutaneous layer approach could removal multiple breast fibroadenoma at one time,patients were satisfacted with the good cosmetic results,we believe this operation method has short operation time and good clinical value.

Objective To observe the abnormality on behavioral ability of transgenic mice for HRX-EEN fusion gene.Methods Transgenic mice for HRX-EEN fusion gene(transgenic group,n=12)and C57/BL mice(control group,n=12)were tested in hidden platform training(day 1 to day 4)and probe trial testing(day 5)in Morris water maze in which ability of spatial learning and retention was assessed.Results In hidden platform training,the latencies of transgenic group were longer than those in control group,and significant differences were observed between the two groups for day 2,3 and 4(P
