Objective To investigate the melanocyte lymphocyte reacion when the allogeneic lymphocytes are cultured with normal melanocytes. Methods 3H-thymidine was incorporated into the mixed culture and the transformation and proliferation rates of lymphocytes were detected by liquid scintillation counting and expressed as cpm. Electron microscopy was used to observe the ultrastructure of melanocytes after mixed culture. Results The results of lymphocyte proliferation were expressed by the stimulation indexes. The stimulation indexes in active vitiligo group was significantly different from that in stable vitiligo group and normal controls. The stimulation indexes of the melanocyte stimulated group was significantly different from that of ConA stimulated group. In the mixed melanocyte lymphocyte reaction, the allogeneic lymphocytes had little effect on the melanocytes. The ultrastructure of the melanocytes in the mixed culture showed normal morphology and normal function of synthesis of melanin. Conclusion As a specific antigen in mixed melanocyte lymphocyte reaction, melanocyte has a weak effect on the lymphocytes. The melanocytes from stable stage vitiligo patients seem more suitble to be allografted.

Objective To analyze the effects of different age and gender on the efficacy and pharmacokinetics of the target controlled infusion of atracurium besylate on liver dysfunction.Methods 160 case of patients with liver dysfunction and undergoing elective general anesthesia operation were divided into four groups according to their age and gender, 40 cases in each group:group A (age≥65 years old, male), group B (age≥65 years old, female), group C (age<65 years old, male), group D (age<65 years old, female).The patients received one-time double dose ED95 atracurium besylate, pharmacodynamic indexes and pharmacokinetic parameters were compared.Results The four groups of patients with block onset time, block maintenance time, clinical duration of T25%, in vivo role time T95%, muscle relaxation recovery index were compared, the difference was not statistically significant.The preoperative and postoperative 24h, four groups of patients with liver function ( alanine aminotransferase, aspartate aminotransferase, albumin, bilirubin) and renal function ( creatinine, urea nitrogen) were compared, the difference was not statistically significant.There was no significant difference between the four groups in the plasma concentrations of the substance to be measured, the peak time, the area under the curve and the elimination half lives.Conclusion For the patients with liver dysfunction, the target controlled infusion of atracurium besylate in general anesthesia operation, gender and age were not considered.

The Ebola virus belongs to the Filovirus family, which causes Ebola hemorrhagic fever (mortality, 25%-90%). An outbreak of infection by the Ebola virus is sweeping across West Africa, leading to high mortality and worldwide panic. The Ebola virus has caused a serious threat to public health, so intensive scientific studies have been carried out. Several vaccines (e.g., rVSV-ZEBOV, ChAd3-ZEBOV) have been put into clinical trials and antiviral drugs (e.g., TKM-Ebola, ZMAPP) have been administered in the emergency setting to patients infected by the Ebola virus. Here, recent advances in vaccines and drugs against the Ebola virus are reviewed.

Objective To investigate the current situation of the use of standard medical terminologies in journal, and analysis the reasons and then find the solutions.Methods Through searching the WANFANG database, we selected the nonstandard and standard terms of 100 common medical terminologies as Search Words, all the fields as Search Options to trace articles in periodicals from Jan.2011 to Dec.2013.After getting the top ten ranked words, the rate of use of the standard terms was analyzed.Results Some journals still use nonstandard terms, standard terms were mixed up with nonstandard terms in all of the 100 medical terminologies.Conclusions More attention should be paid to the use of the standard medical terms in periodicals to unify and standardize the use of medical terms.

RIG-I-like receptors (RLRs) belong to pattern recognition receptors, which perform significant roles in antiviral responses. RLRs can initiate a cascade of signaling transduction that induces the production of type I interferon and activates the interferon signaling pathway, ultimately resulting in antiviral responses. In the course of evolution, viruses have been constantly counteracting host immune systems to facilitate their own survival and replication, and have developed a set of antagonistic strategies. These mainly comprise elusion, disguise and attack strategies to eliminate the activation of RLRs. In virus-infected cells, RLRs recognize viral RNA and then induce antiviral responses. A better understanding of viral antagonistic strategies against RLRs will provide insights into the development of new antiviral medicines. This mini-review concludes that there are three main antagonistic strategies by which RNA viruses can counteract the activation of the RLRs pathway. It aims to provide references and insights for similar studies on viral antagonism in an array of RNA viruses.

Objective To investigate the effect ofnarrow-band ultraviolet-B(NB-UVB)(311 nm)on dendrite formation in B16 melanoma cells.Methods B16 melanoma cells were irradiated with various doses of NB-UVB(0,25,50,100,200,300 mJ/cm2).Atier additional culture of varying durations,irradiated cells were harvested and subjected to the observation of morphological changes and cell cytoskeleton F-actin microfilaments by phase contrast microscopy and laser scanning confocal microscopy(LSCM).respectively,and to the detection of cell proliferation bv MTT colorimetric assay.Pull down assay was performed to detect the activity of GTP-RhoAA and GTP-Rac1 in B16 cells before and after UVB irradiation.Results Twenty-four hours after irradiation with UVB of 100 mJ/cm2.an increase was observed in the cell body of B16 cells which appeared in sphericity,as well as in the number of dendrites(P＜0.01)which showed a branch-like appearance.compared with non-irradiated cells which had 2-3 dendrites and obscure branches.LSCM revealed that F-actin microfilaments in B16 cells were well organized with clear textures before irradiation;after irradiation wim NB-UVB of 100 mJ/cm2.stress fibers were disassembled and disrupted and the texture became unclear,which was observed as early as 30 minutes and became more and more evident,and at 6 hours the stress fibers displayed a clumping appearance with obscure textures.Following the irradiation with NB-UVB of 100 mJ/cm2,the expression level of GTP-Rac 1 protein increased at l 5 minutes,and.at 30minutes,reached 2 times of that observed in nonirradiated cells,then decreased a liale,but still remained elevated at 60 minutes and 120 minutes,compared to unirradiated cells;meanwhile.the level of GTP-RhoA dropped a little at 30 minutes,then gradually increased and,at 120 minutes.reached 1.6 times of that observed in unirradiated cells.Conclusion Narrow-band UVB(311 nm)can promote dendrite formation.likely via regulating the expression of GTP-Racl and GTP-RhoA in B16 melanoma cells.

Objective To investigate the cytolytic activity of extracellular cytolytic toxin rVVC of Vibrio vulnificus on the apoptosis of human ECV304 cells, and to analyze the activities of Caspase-3,-8 and -9. Methods The cytotoxic effect of refolded rVVC on the growth and apoptosis of ECV304 cells was identified by MTT, Hochest33342/PI fluorescent staining, flow cytometry and DNA agarose electrophoresis analysis, respectively. The activities of Caspase-3, -8 and -9 was measured using a colorimetric method. Results The viability of human ECV304 cells exposed to rVVC was inhibited by rVVC after 24 h. 2.0 HU/ml rVVC groups had a better cytotoxic effect to human ECV304 than that of 0.5 HU /ml rVVC groups. The apoptosis of human ECV304 cells in 2.0 HU/ml rVVC+40 μmol/L Z-VAD-FMK groups was relative reduced than that of 2.0 HU/ml of rVVC groups. After 0.5 h treatment with 2.0 HU/ml of rVVC, the Caspase-3 activity in human ECV304 cells increased gradually and reached the peak at 3 h (versus control groups, P<0.01). The activity of Caspase-8 and -9 remained unchanging. Conclusion The rVVC has cytotoxic effect on human ECV304 and the cytolysin is probably correlated with Caspase-3.
