2.Study progresses in respiratory mucosal immunity and related diseases
Chinese Journal of Immunology 2015;(3):289-294
As the passage of environmental atmosphere entering the body,the respiratory tract suffers persistent challenge from foreign substances.The mucosal immune system of the respiratory tract is the main defense line against the invasion of pathogens,which needs to distinguish not only beneficial and detrimental materials but also resident and pathogenic bacteria.Because the knowledge about respiratory mucosal immunity is limited,the immunopathologic mechanisms of related diseases such as asthma,acute lung injury, chronic obstructive pulmonary disease, and respiratory infection need investigation.The study about the immune features of the respiratory tract not only contributes to the prevention and treatment of respiratory disease but also provides ideas for the development and design of new vaccines and medicines.

Objective To evaluate argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) in treating primary hepatocellular carcinoma by comparing the changes of AFP level and T cell immunity after the therapy with that obtained after the treatment of argon-helium cryoablation alone and with that obtained after the treatment of TACE alone. Methods (1) Ninety-nine patients with primary hepatocellular carcinoma were randomly divided into three groups: group A (n=30), treated with argon-helium cryoablation; group B (n=34), treated with TACE; and group C (n=35), treated with argon-helium cryoablation together with TACE. The patients' gender, age and pathology of three groups were comparable with each other. (2) The peripheral blood T cell immunity and AFP level both before and after the treatment were determined and the results were statistically compared. Results After the treatment the AFP level in all 3 groups was significantly reduced when compared to that determined before the treatment (P < 0.05). And the difference in the decrease of AFP level between group C and A, also between group C and B, was statistically significant (P < 0.05). After the treatment the T cell immunity, including Th, TS and Th / TS, in all 3 groups was significantly different from that determined before the treatment (P < 0.01), and significant difference also existed between group C and A and between group C and B (P < 0.01). Conclusion The statistic analysis of AFP and T cell immunity, which are regarded as the index of therapeutic efficacy, indicates that argon-helium cryoablation combined with TACE is superior to simple argon-helium cryoablation and also to simple TACE in the treatment of primary hepatocellular carcinoma.

Objective To analyze the relationship between the chemotherapeutic efficacy and VEGF expression in the patients with oral squamous cell carcinoma. Methods 51 cases with oral squamous cell carcinoma who received preoperative chemotherapy of a total 80mg pingyangmycin were enrolled in this study. The relationship among the chemotherapeutic effect, VEGF expression, fever, and the duration of fever was analyzed using linear correlation, stepwise regression and student t-test. Results VEGF expression in the cancer cells of 92.1%(47/51) patients decreased after preoperative chemotherapy, and the decreased expression of VEGF was not significantly correlated with chemotherapentic efficacy. But the chemotherapeutic effect was closely related with fever degree in the early stage of chemotherapy. Conclusion There was no significant relationship between chemotherapeutic effects and VEGF expression in oral squamous cell carcinoma. Fever in early stage of chemotherapy may serve as an index for evaluating the patient prognosis.

The completion of sequencing human genome creates a new era of biological science and technology. Although the sequence of the human genome has been known, it is still hard to rapidly explore the whole functional genes, especially, their interaction with each other and the meaning to the body. However, the "reverse biology" which comes into being in the recent years provides us a series of novel ideas and technologies for discovering new functional gene, among which the immune-related genes have attracted more attentions, clarifying how functional gene works and their potential value in application.

MicroRNAs (miRNAs) are another interest of small, non-coding RNAs, which regulate gene expression at post-transcriptional level in a sequence-specific manner. Recent researches demonstrate that miRNAs play important roles in innate immune response at various phases in vertebrates. In order to eliminate pathogens such as virus, miRNAs are crucial molecules in signaling of innate immune, and also in directly interfering in virus replication, therefore, miRNA may work as one important aspect of classical innate immune response against pathogenic microorganism. Meanwhile, pathogenic microorganism, especially viruses, can encode miRNA or regulate the miRNAs expression in host cells to disturb the expression of many immune associated genes directly and/or indirectly, so that they can escape from immune attacking. So, pathogenic microorganism and their hosts might fight with each other at miRNA level immediately after infection in the earliest phase.
