The Markov property of Markov process functionals which are frequently used in economy, finance, engineering and statistic analysis is studied. The conditions to judge Markov property of some important Markov process functionals are presented, the following conclusions are obtained： the multidimensional process with independent increments is a multidimensional Markov process; the functional in the form of path integral of process with independent increments is a Markov process; the surplus process with the doubly stochastic Poisson process is a vector Markov process. The conditions for linear transformation of vector Markov process being still a Markov process are given.

In this paper, we investigate a two electronic level system with vibrational modes coupled to a Brownian oscillator bath. The difference frequency generation （DFG） signals and sum frequency generation （SFG） signals are calculated. It is shown that, for the same model, the SFG signals are more sensitive than the DFG signals to the changes of the vibrational modes of the electronic two-level system. Because the SFG conversion efficiency can be improved by using the time-delay method, the findings in this paper predict that the SFG spectrum may probe the changes of the microstructure more effectively.

The growth and development of skeletal muscle also determine the meat production of yak, ultimately affecting the economic benefits. Hence, improving growth performance is a top priority in the yak industry. Skeletal muscle development is a complex process involving the regulation of several genes, including microRNAs(miRNAs). However,the transcription of miRNAs in yak skeletal muscle during prenatal to postnatal stages is unknown. We used small RNA sequencing(small RNA-Seq) to determine the global miRNAs of longissimus dorsi muscle from yak(the samples were collected from three fetuses and three adults). Totally 264 differently expressed miRNAs(|log2(fold change)|>1and P-value≤0.05) were detected between the two groups. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis showed that differently expressed miRNAs-targeted genes participated in pathways associated with muscle development, such as MAPK, PI3K-Akt, and Hippo signaling pathways, etc. MiR-652, which was up-regulated in the fetal group, was transfected into C2C12 myoblasts to examine its role. miR-652 promoted(P≤0.05)proliferation and differentiation, but inhibited(P≤0.001) apoptosis at early period. Furthermore, miR-652 reduced(P≤0.001) the proportion of C2C12 myoblasts in the G1 phase while increasing(P≤0.01) the proportion of cells in the S and G2 phases. Dual-luciferase reporter assays indicated that ISL1 served as a target of miR-652. In general, these findings expand our understanding of yak skeletal muscle miRNAs, and suggested that miR-652 probably regulated myogenesis by regulating ISL1.

Fuzheng Jiedu granule exhibits a number of health benefits and it is thought that the mechanisms involved in these effects are due to the modulation of immunity. In this article, we studied the effect of Fuzheng Jiedu granule on immunological function and the expression of immune-related cytokines in immune-suppressed mice. 72 mice were randomly divided into six groups, with 12 in each group. The control groups included an untreated group, a negative control group（Cyclophosphamide） and a positive control group（Astragalus polysaccharide）. There were three treated groups, which were given different doses of Fuzheng Jiedu granule： a low dose（100 mg kg^（–1））, a medium dose（400 mg kg^（–1）） and a high dose（600 mg kg^（–1））. With the exception of the untreated control animals, each group received an intraperitoneal injection of Cyclophosphamide（100 mg kg^（–1）） for 3 days to establish the immune-suppressed model. Mice were then treated for 19 consecutive days and, 24 h after the last treatment, blood was taken for the eyeballs and serum separation was performed. Analysis was made of the levels of related cytokines（IgA, IgG, IgM, IL-6, IFN-γ, C3, C4 and TNF-α）, the transformation of lymphocytes and the immune organ indexes. The results showed that Fuzheng Jiedu granule can improve the levels of cytokines, the rate of proliferation of lymphocytes and the immune organ indexes of immune-suppressed mice.
