2.The potential role and significance of tumor necrosis factor-α induced protein 8 like-2 in autoimmune diseases
Medical Journal of Chinese People's Liberation Army 2017;42(8):749-752
Autoimmune disease is a condition arisen from an abnormal immune response to the tissue cells itself, its precise mechanism remains unknown, and the failure to distinguish self from non-self is often termed a breach of tolerance and is the basis for autoimmune illness. The tumor necrosis factor-α (TNF-α) induced protein 8 like-2 (TIPE2) is a newly discovered member of TNF-α induced protein 8 (TNFAIP8) family which is an essential negative controller of both innate and adaptive immunity. It has been documented that marked expressions of TIPE2 are evident in various autoimmune diseases, including autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), myasthenia gravis (MG) and systemic lupus erythematosus (SLE), which appear to be closely related to the severity, progression as well as prognosis of the illness, thereby contribute to the pathogenesis of autoimmune diseases. Deficient expression of TIPE2 might contribute to the hyper-reactivity of auto-reactive lymphocytes and macrophages, or aggregate inflammatory reaction by prompting high concentration of pro-inflammatory cytokines in peripheral blood, thus, trigger the development and progression of autoimmune diseases. In addition, dysregulation of immune homeostasis could be another latent target involved into the mechanism of autoimmune diseases. The present paper summarized the potential role and its mechanism of TIPE2 in the development of autoimmune diseases.
3.11? Hydroxysterold dehydrogenases and type 2diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 1986;0(03):-
11? Hydroxysterold dehydrogenases (11?-HSDs )catalyse the interconversion of active glucocorticoids(cortisol,corticosterone )and their inert 11?-keto derivatives(cortisone,11-dehydrocorticosterone)They play an important role in regulating the local glucocorticoids activities.Glucoeorticoids can induce insulin resistance.The alteration of 11?-HSD activities in tissues such as liver ,adipose tissue, is closely relevant to some common disorders,including obesity and type 2diabetes mellitus.

Chinese Pharmacological Bulletin 1986;0(06):-
hydroxysteroid dehydrogenase (11? HSD) catalyzes the interconversion of cortisol with its inactive metabolite cortisone. The congenital deficiency of 11? HSD2 induce hypertension and hypokalemia. This disorder is called "Apparent Mineralocorticoid Excess(AME)". Glycyrrhizic acid and other endo and xenobiotics have been found to inhibit the activity of 11? HSD and cause excess mineralocorticoid effects that is similar to AME. The decrease in 11? HSD activity is related with the acquired and congenital hypertention.
5.The Peroxiredoxins protein family and related disease
Journal of Medical Postgraduates 2015;(1):98-101
Peroxiredoxins(Prxs) are a family of antioxidant protein that have been identified in prokaryotes and eukaryotes. As antioxidants, Prxs protein contains an active site cysteine that is sensitive to oxidation by H 2 O2, eliminate active oxygen that exist in normal tissues and cells, protect cells from oxidative damage induced by reactive oxygen species ( ROS). Prxs protein is a known free radical scavenger, and has been shown to play a role in several diseases. In this review, recent advances on the study of Prxs protein family and tumor related diseases are reviewed, which is expected to provide new ideas for the diagnosis and treatment of the related clinical diseases.
6.Important role of interleukin-35 in infectious diseases and its significance
Chinese Critical Care Medicine 2017;29(9):848-852
Infectious diseases are resulted from the invasion of an organism's body tissues by multiple disease-causing agents. It has been demonstrated that the occurrence and development of infectious diseases are closely associated with the functional status of immune system. Cytokines play significant roles in modulating the host immune response to the clearance of pathogenic microorganisms and maintaining immune homeostasis. Interleukin-35 (IL-35), as a newly identified member of IL-12 family, exerts suppressive effect on immune response by means of a specific pattern. With the progress of research in recent years, IL-35 might serve as an essential contributor in the immunopathogensis of vast infectious diseases, including hepatitis B, sepsis, tuberculosis and parasite infection, which simultaneously appear to be closely related to the severity, progression as well as prognosis of the illness. Apparently, IL-35 is regarded as a potent and promising anti-inflammatory cytokine in clinical application; its potential value may shed light on the therapeutic strategies for infectious diseases. Herein, we mainly review the potential role and its mechanism of IL-35 in the pathogenesis of infectious diseases.

Objective To investigate the effect of stress induced by fear on germ cells apoptosis in rat's testis. Methods 36 SD rats were randomly assigned to acute stress group, subacute stress group, chronic stress group and control group, respectively. The model of the stress rat induced by fear was reproduced. The levels of caspase-3 mRNA and bax /bcl-2 mRNA expression in rats' testis were determined by fluorescent quantitative RT-PCR. The apoptosis of spermatogonic cell, primary spermatocyte, secondary spermatocyte and spermatid was identified by TUNEL. Results Caspase-3 mRNA, compared with that in control group, was expressed highly in the subacute stress group (5.34?1.13 vs 3.67?0.34, P0.05). The ratio of bax /bcl-2 mRNA, compared with that in the control group, was increased significantly in the subacute stress group (2.68?0.86 vs 1.60?0.42, P0.05). Compared with that in control group (1.50?0.58), the apoptotic index of germ cells was higher in the subacute stress group (10.50?1.29, P0.05). Conclusion Stress induced by fear plays an important role in inducing germ cells apoptosis, and caspase-3, bax and bcl-2 were involved in this process.
