Background and purpose:With widely use of anthracyclines,patients are easily failed to respond to anthracyclines baseal regimens chemotherapy.Docetaxel and capecitabine(xeloda)are usually considered as the most active agents in breast cancer and are often used as adjuvant chemotherapy.In this study,we evaluated the efficacy and toxicity of docetaxel and xeloda combination regimen in the treatment of patients with metastatic breast cancer and previously treated with anthracyslines.Methods:64 patients who previously failed to respond to adriamycin based chemotherapy received docetaxel and xeloda combination regimen,docetaxel 75 mg/m2 ivgtt,day 1;xeloda 1 250 mg/m2,twice daily,day 1-14.The regimen was repeated every 21 days and the clinical response was recorded after 2 cycles.The effective patients received at least four cycles.Results:In 64 patients,the overall response rate was 60.9%,with 6 patieuts CR and 33 patients PR.The most frequent treatment-related adverse events were leukopenia, fatigue,nausea,vomiting and hand-foot syndrome.The main reactions were myelosuppression,Ⅲ-Ⅳwas 45.8%. Conclusion:Good clinical efficacy were achieved in the therapy of metastatic breast cancer with docetaxel and xeloda combination regimen and toxic reactions are tolerable.

Objective:To research the imumunological effect of dendritic cell transfected by recombinant plasmid of ΔNp73αon breast cancer.Methods:Cultivate dendritic cells by cytokines( GM-CSF,IL-4,TNF-α) from human umbilical cord blood in vitro, CD1a,CD83 were detected by flow cytometry.Recombinant plasmid pcDNA-HA/ΔNp73αwas used to transfected DCs,the transfection was detected by Western blot.Transfected DCs cocultivate with T cell induce specific cytotoxic lymphocytes( CTL).Proliferation ability of T cell was detected by MTT methods.IFN-γin the culture supernatant of the transfected DCs were detected by ELISA.The killing effect on breast cancer MDA-MB-231 was detected by LDH method.Results:The expression of CD1a(56%),CD83(74%)in mature DC was higher than immature DC(CD1a 19%,CD83 13%)(P<0.01).ΔNp73αtransfected group had a special band.The killing effect of specific CTL induced byΔNp73α-DC and T cells cocultivation on breast cancer cell MDA-MB-231 was statistic stronger than DC group(P<0.05),the proliferation of T cell and secretion level of IFN-γcompared with DC and pcDNA group were statistically significant(P<0.01).Conclusion:The CTL induced byΔNp73αtransfected DC vaccine has significant effect on killing breast cancer.

Background Misfolding of Myocilin protein plays an important role in the pathogenesis of primary open angle glaucoma (POAG).GRP78 can transfer the misfolded proteins out endocytoplasmic reticulum and keep the protein synthesis function of endoplasmic reticulum.However the relationship between GRP78 and Myocilin in the pathogenesis of POAG has not been elucidated.Objective This study was to investigate and analyze the coexpressions of GRP78 and Myolicin in trabecular meshwork cells (TMCs) of POAG.Methods The trabecular meshwork tissues were obtained during the surgery of POAG and healthy donor for the isolated and in vitro culture of TMCs,and the morphology of the cells was compared between POAG-derived TMCs and donor-derived TMCs.The expression of specific factors for TMCs were detected by immunochemistry.The cells were divided into normal control group,tunicamycin (Tm)-treated group and staurosporine (STS)-treated group,and the cells were cultured by regular medium,the 1 μ mol/L Tm medium or 0.1 μmol/L STS medium for 24 hours respectively.The co-expression of GRP78 and Myocilin in the cells were detected using immunofluorescence assay.This study was approved by Ethics Committee of Xi'an No.4 Hospital,and written informed consent was obtained from each patient before surgery.Results Primarily cultured cells showed the fiat star-like and irregular appearance with 3-5 processes,round nuclei,abundant cytoplasm and black engulf particles.The 3-7 generations of POAG-derived cells grew well,showing positive expressions of laminin (LN),fibronectin (FN),neuronal specific enolase (NSE) and Vimentin.Immunofluorescence assay showed positive expressions of GRP78 and Myocilin in the cells of the Tm group,STS group and normal control group,with the reddish and green fluorescence separately.Incomplete co-expression of GRP78 and Myocilin was seen in donor-derived TMCs,and complete co-expression of GRP78 and Myocilin was found in the POAG-derived TMCs in the normal control group.Complete co-expression of GRP78 and Myocilin was exhibited in both donor-and POAG-derived TMCs in the Tm group and STS group.In addition,accumulation of GRP78 protein around nucleus was seen in both donor-and POAG-derived TMCs in the Tm group.Conclusions GRP78 and Myocilin proteins are completely co-expressed in POAG-derived TMCs,inferring that GRP78 and Myocilin play an interaction role in the pathogenesis and development of POAG.GRP78 may play a cytoprotective role against the apoptosis of TMCs caused by endoplasmic reticulum stress.

Xenotransplantation is a feasibility way of solving the shortage of human organs for transplantation. Although it is urgently needed to satisfy the demand of people and sustain the function of human organs, there are multiple hurdles existed to clinical application, such as the immune rejection between human body and the xenografts, the infection of pathogens and a series of ethic, morality and social issues. A historical retrospect of xenotransplantation was given, and then probe into the strategies according to the main problems and the actualities. Finally, the prospect in the field of xenotransplantation was showed.

OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.

METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.

RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).

CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.
