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.

[Objectives]To extract Yang Lishan’s description of latent evils ,summarize his arguments, and provide reference for exploring his academic ideology further. [Methods] Use the literature methodology, take“latent evils”and“pestilential pathogen”as keywords, retrieve the related description in Yang Lishan’s book, summarize his main opinions on latent evils. [Results] Yang Lishan wholly refused the theory of latent cold evil turning into pathogenic warm, and he believed that the cause of latent evils is pestilential pathogen, thereby distinguishes warm disease from exogenous febrile disease on etiology level. He described the disease’s quality, afferent pathway, hiding spot, the way out, therapeutic method, prescription and recuperation in details, which are mature enough to form a complete theoretical system. The prescription Sheng Jiang Powder represents experiment with the thought of treating pestilential pathogen with drugs and special medicine for special disease, which makes the etiology of pestilential pathogen to have real directive value. [Conclusion] Yang Lishan’s theory of latent evils has implications in treatment and prevention of epidemic diseases.

EB virus (EBV) is a ubiquitous y-herpes virus,which asymptomatically infects greater than 90 ％ of the world's population.EBV is closely related to development of several kinds of lymphomas that include B-,T-and NK-cell derived.Subsequent studies have proven that EBV gene expression product plays an activating and/or promoting role on lymphomagenesis,and paves the way for EBV associated lymphomas immunotherapy.This review focuses on the EBV associated lymphomas in 2008 WHO classification of tumours of haematopoietic and lymphoma tissues.

Objective:To explore the effects ofbufalin (BUF) combined with doxorubicin (DOX) on the proliferation and apoptosis in human lung cancer cell line A549 in vitro.Methods:Methyl thiazolyl tetrazolium (MTT) assay was used to measure the inhibitory effects of BUF,DOX and their combination on the growth ofA549 cells.Hoechst 33342 staining was used to observe the changes of nucleus.Flow cytometry was used to investigate the apoptosis and cell cycle distribution of A549 cells.Western blot was used to examine the expression of apoptotic protein.Results:BUF and DOX showed inhibitory effect on the A549 cells in a dose and time-dependent manner.Compared with BUF or DOX alone,combination of BUF (1,20,100 nmol/L) with DOX (1.0 μg/mL) could significantly increase the growth inhibition rate ofA549 cells at 24,36,72 h,respectively (all P＜0.05).BUF and DOX alone could induce apoptosis,and their combination could significantly increase the apoptosis ratio.In addition,BUF combined with DOX could block the cell stage of A549 cells,keep the cell stage stay in S stage and up-regulate the expression of caspase-3.Conclusion:BUF combined with DOX can significantly inhibit the proliferation ofA549 cells,which might be related to the induction of apoptosis,cell cycle S phase arrest and caspase-3 up-regulation.

Stem cells offer considerable promise in the repair or replacement of damaged tissue in the body.Mature and functional endothelial cells play a pivotal role in neovascularization and maintenance of blood vessel integrity.Although being the best choice for transplantation endothelial,cells isolated from autologous vessels have been heavily obstacled in medical application due to poor resources and limitted proliferation potential in culture.Thus,stem cells have been the focus of the studies soareh for suitable cell sources.Several types of stem cells have been reported to possess endothelial cell differentiation potential.This article summarized the recent study on the sources,distribution,features-differentiation,animal experiments and clinical use of stem cells.Advantages and disadvantages are compared to provide a reference for the choice of evdothelial celia source.

Lipid emulsion has been used not only as nutrition in clinic practice,but also recently as an adjuvant therapy of lipophilic drugs poisioning,which is most likely to cause cardiopulmonary arrest and brings difficulty to conventional treatments.More and more reports of whether studies in labs or clinic cases suggest that lipid emulsion can be adopted as one of therapies for lipophilic drugs poisioning.The article mainly sums up the development of lipid emulsion remedy against lipophilic drugs poisioning in the hope of providing reference for clinical application of lipid emulsion to detoxification.

Objectives To investigate the association between HLA-DQB1 alleles and Han Chinese with generalized pustular psoriasis (GPP) from Shandong. Methods The distributing frequencies of HLA-DQB1 alleles were detected with polymerase chain reaction-sequence specific primers (PCR-SSP) in 38 GPP patients and 94 healthy subjects from Shandong. Results ①The frequencies of HLA-DQB1*0201 and *0603 alleles increased significantly in GPP patients compared with those of the healthy controls(Pc = 0.005 and Pc = 0.013 , respectively), and the frequency of HLA- DQB1*0604 alleles decreased (OR = 0.08, Pc = 0.039). ②There were significant association between the GPP patients with a previous history of psoriasis vulgaris and HLA-DQB1*0201 and *0603 alleles (OR = 32.31, Pc = 0.005; OR = 12.42, Pc = 0.005, respectively), and between the GPP patients without the history and HLA-DQB1*0602 alleles (OR = 5.60, Pc = 0.039). Conclusions HLA-DQB1*0201 and *0603 alleles are significantly associated with the Chinese patients with GPP in Han population from Shandong. There is a significant heterogeneity in the GPP patients with and without the history of psoriasis vulgaris.

Objective To establish a model of DRG-like grouping of cesarean section patients in the Beijing area so as to observe its feasibility of controlling rising medical costs.Methods DRG-like grouping of cesarean section patients was conducted by case-mix/DRG.The patients were divided into 3 groups according to complications: the serious complication group,the moderate complication group,and the minor or no complication group.Results The rate of cesarean sections remained at 50% or so in Beijing.A statistical analysis showed a significant difference between the 3 groups in costs and length of hospital stay.70% of the cases in the serious complication group belonged to the high cost group whereas 70 % of the cases in the minor or no complication group belonged to the low cost group.Conclusion The main ways of controlling rising costs for cesarean sections include reducing the rate of cesarean sections and(adopting) DRG-like PPS payments in view of the nature of medical insurance and government payments for cesarean sections.

12 cases of human placentas were obtained after administration of Chinese medicinal herb (Chuan-Xin-Lian) -induced abortion during mid-pregnancy. Six placentas from curettage induced abortion during mid-pregnancy were used as controls. All the specimens were studied histochemically and immunohistochemically by using antiserum to HCG with PAP method. In most of the specimens from women treated during mid-pregnancy, we observed a decreased immunoreaction of antiserum to HCG and a decrease of RNA content in the syncytiotrophoblasts. Increased activity of acid phosphatase in dccidual cells was observed during mid-pregnancy. These findings indicate that during mid-pregnancy, Chinese medicinal herb (Chuan-Xin-Lian) can reduce the synthesis of HCG in syncytiotrophoblasts and can initiate uterine contractions, so that abortion results. The possibility that the changes of lysosomal enzymes are involved in the initiation of uterine contractions is disscused.

Objective To investigate the diagnostic value of serum high density lipoprotein cholesterol (HDL-C), serum albumin (SA) and C reactive protein ( CRP) levels combined detection of severe acute pancreatitis.Methods 180 cases of acute pancreatitis were selected from January 2012 to January 2015 in Tianjin fifth central hospital,including 87 severe acute pancreatitis ( SAP) and 93 mild acute pancreatitis ( MAP) , and 100 cases of healthy people were selected as control group.The serum levels of HDL-C, SA and CRP were compared among three groups.Results HDL-C and SA in SAP group and MAP group were significantly lower than control group (P<0.05), the level of CRP was significantly higher than that of control group ( P<0.05); HDL-C, SA levels in SAP group were significantly lower than those of MAP group, the CRP level was significantly higher than that of MAP group (P<0.05).Compared to HDL-C and SA, the sensitivity(89.4%), specificity (95%) and accuracy (92%) of CRP were significantly higher (P<0.05).The sensitivity(93.6%)and specificity (95%) and accuracy (94.3%) of combined detection of three markers were significantly higher than the detection results of the three indexes either,the differences were statistically significant (P <0.05).Conclusion The combined detection of serum HDL-C, SA and CRP levels can effectively improve the early diagnosis rate of SAP, and provide reference for clinical diagnosis.
