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.

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.

Objecitve To conclude the clinical manifestation of Fournier's gangrene (FG) and its emergency treatment.Methods From 2006 to 201 1,12 patient were involved in the study,all had received debridement,wide spectrum antibiotics and support therapy,the clinical manifestation,treatment choice and prognosis were analyzed retrospectively.Results All patients were male with 67.7 year-old mean age.Initial lesions were all in scrotal skin,an average procedures of each patient was 3.5,mean hospitalization days was 29.7 days.Surgical wound was healed by left scrotal skin in all cases,2 cases with huge urethra defect were received perineostomy.Ten cases were survived with 57-months follow-up and mortality was 16.7％.Conclusions Fournier is one of emergency disease of Urology.Its mortality is still high.Intensive care and appropriate anti-biotic therapy combined with surgical treatment is the key of FG's management.

Objective Base on the theory of traditional Chinese medicine (TCM), obtained human diagnostic information available for joint syndrome differentiation is integrated based on subjective and objective combined syndrome differentiation, in the form of data expression of TCM four diagnosis, forms multiple information fusion of open platform for TCM diagnosis and treatment, and provides some revelation for promoting the development of depression and treatment technology. Methods Totally 30 depression patients and 30 normal people were selected according to the inclusion criteria. TCM four diagnostic and auxiliary diagnosis instrument was used to collect information of four diagnosis, and the statistical software was used for the analysis on pulse diagnosis, and information features of digitalized tongue and listening diagnosis of patients in depression group and normal group were studied. Results Compared with depression group, pulse frequency, fluency, and heart rate of normal group were a bit higher than depression group, without statistical significance (P>0.05);There was statistical significance among pulse frequency, strength, tightness, and pulse wave velocity between the normal group and depression group (P<0.05). 30 patients had 6 depression syndrome types:heart-gallbladder qi deficiency (8 cases), phlegm-heat attacking internally (6 cases), fire excess from yin deficiency (6 cases), liver depression forming fire (6 cases), intense heart fire (3 cases), and heart-spleen deficiency (3 cases). Conclusion The results of differences in pulse diagram parameters were consistent with the theory of classical TCM pulse theory. The results of differences in pulse wave velocity conform to the modern medical research conclusion. TCM four diagnostic auxiliary diagnosis and treatment technology can realize the dynamic detection of depression patients with four diagnostic information, and establish diagnostic methods for depression based on digitalized four diagnostic auxiliary diagnosis.

RNA interference mediated by short interfering RNA is widely used to study functional genes and also being developed for therapeutic applications. However, recent study demonstrated that siRNA might activate innate immune system and induce huge production of inflammatory cytokines in mammals, and also randomly inhibit expression of undesired genes. Designing highly effective siRNAs or modifying the siRNA to retain or enhance the silence efficiency and meanwhile abolish the off-target effects associated with immunostimulation then become the key techniques in application of siRNAs as safe and effective therapeutic agents.
