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.

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 prove the clinical therapeutic effect of acute and chronic bronchial asthma with Chuankezhi(CKZ) Injection. Methods: 40 cases of bronchial asthma, including inpatients and outpatients were selected, divided into the attack period group (20) and the relief period group (20). The former was intramuscularly injected CKZ injection 4mL, twice a day, 14 days being a course of treatment. The latter was intramuscularly injected CKZ injection 4mL, twice a day for 15~30 days and 2mL, every other day for 31~90 days; 90 days being a course of treatment. The symptoms and signs, such as asthma, cough, expectroation, pulmonary wheeze were observed. and pulmonary function, absolute eosinophilic granulocyte count and immunogobulin E were measured before and after treatment. Result: By the use of CKZ injection to treat bronchial asthma, the total effective rate amounted to 85% and obvious difference before and after treatment in the two groups ( P

Two thermotolerant, ethanol-producing yeast cultures: THFY-4 and THFY-16 were isolated from 381 nature samples. THFY-4 can grow on 30% glucose plate at 51 ℃,while THFY-16 can grow on the same medium at 45℃.After preliminary ide ntification, THFY-4 was identified as Kluyveromyces sp. and THFY-16 belon gs to Saccharomyces genus. The ethanol fermentation experiment shows that T HFY-4 can only produce 4.88% (v/v) ethanol from 20% glucose after 60 hours, wh ile THFY-16 can produce 11.44% ethanol under the same condition. When using s accharified Canna edulis Ker wort as fermentation medium, 9.43%(v/v) ethanol we re produced from 16.1% glucose, which is 91.0% of the theoretical yield.
