As the body ages， the immune system will undergo a series of changes， which are termed "immunosenescence" and are embodied in immune cells. Previous studies have shown that the immune cells involved in the regulation of immunosenescence include intrinsic immune cells and adaptive immune cells. Intrinsic immune cells are neutrophils， monocytes/macrophages， myeloid-derived suppressor cells， dendritic cells， natural killer cells， etc.， and the underlying mechanisms involve the regulation of cell number， phagocytosis， chemotaxis， adhesion， the function of toll-like receptor （TLR）， antigen presentation， macrophage polarization， cytotoxicity， migration， etc. The adaptive immune cells include T-lymphocytes and B-lymphocytes， and the underlying mechanisms involve the regulation of cell development， proliferation， differentiation， cell number， telomerase activity， self-reactive antibodies， etc. Immunosenescence is the manifestation of aging in the human body and is also an important target for delaying aging by Chinese medicine and western medicine. In recent years， scholars have found some classical prescriptions and their active components （such as Dushentang and total saponins in Panax ginseng leaves， and Shengmaiyin and anwulignan and total saponins in P. ginseng stems and leaves） can regulate immunosenescence by targeting the immune cells and interfering with their molecular regulatory mechanisms. In addition， the mechanisms of the classical prescriptions in regulating immunosenescence are closely related to autophagy. The representative prescription embodying the therapeutic principles of resolving blood stasis and promoting regeneration， Dahuang Zhechongwan， can delay D-galactose-induced renal aging in mice， and its underlying mechanisms are related to the regulation of the number and activity of thymic immune cells and improvement of the protein expression of autophagy-related markers and inflammatory cytokines in the kidney. Therefore， exploring the effects of the classical prescriptions and their active components by targeting the mechanisms of immunosenescence will become a new direction for investigating and developing anti-aging drugs.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5

OBJECTIVETo investigate the association between rs9722 polymorphisms in the S100B gene and hand, foot and mouth disease (HFMD) caused by enterovirus 71.

METHODSA total of 124 HFMD children with enterovirus 71 infection were enrolled as subjects, and 56 healthy children were enrolled as control group. The rs9722 polymorphisms in the S100B gene were detected for both groups, and the serum level of S100B protein was measured for 74 HFMD children.

RESULTSThe rs9722 locus of the S100B gene had three genotypes, CC, CT, and TT, and the genotype frequencies were in accordance with Hardy-Weinberg equilibrium. Compared with the control group, the HFMD group had significant increases in the frequencies of TT genotype and T allele (P<0.01). Children with severe HFMD caused by enterovirus 71 infection had significantly higher frequencies of TT genotype and T allele than those with moderate or mild HFMD (P<0.05). Compared with the cured patients, the patients with poor prognosis had significant increases in the frequencies of TT genotype and T allele in the rs9722 locus of the S100B gene (P<0.05). Among the 74 children with HFMD, the children with TT genotype had the highest serum level of S100B protein, and those with CC genotype had the lowest level (P<0.01).

CONCLUSIONST allele in the rs9722 locus of the S100B gene might be a risk factor for severe HFMD caused by enterovirus 71 infection.

Objective: To observe the effect of miR-155 on angiotensin Ⅱ (AngⅡ)-induced mice vascular smooth muscle cell (VSMC) phenotype switching with its possible mechanism. Methods: Primary cultured mice VSMCs were treated by AngⅡ at different concentrations and time periods, relevant expressions of miR-155 were examined by RT-PCR. qRT-PCR was conducted to determine miR-155 changes in Blank control group, miR-155 mimics group, miR-155 mimics negative control (NC) group, miR-155 inhibitor group and miR-155 inhibitor NC group. Western blot analysis was performed to measure the effect of miR-155 on AngⅡ-enforced ERK1/2 and mTOR signaling pathway in Blank control group, AngⅡ group, miR-155 mimics group, AngⅡ+miR-155 mimics group, miR-155 inhibitor group and AngⅡ+miR-155 inhibitor group; to detect the impact of miR-155, rapamycin (Rap) and U0126 on AngⅡ promoted VSMC phenotype switching in Blank control group, AngⅡ group, miR-155 mimics group, AngⅡ+miR-155 mimics group, AngⅡ+U0126 group and AngⅡ+Rap group, and to detect protein expressions of SM22α, α-SM-actin (contractile phenotype marker protein) and OPN (synthetic phenotype marker). Results: AngⅡ decreasing miR-155 expression was in a dose- and time-dependent manner. miR-155 could reduce the basal and AngⅡ-promoted ERK1/2, mTOR signaling pathway, while miR-155 inhibitor could elevate the above effect. Rap, U0126 and miR-155 could inhibit AngⅡ-attenuated expressions of SM22α, α-SM-actin and meanwhile inhibit AngⅡ-enforced expression of OPN. Conclusion: miR-155 could inhibit mice AngⅡ-promoted VSMC phenotype switching which might be via inhibiting the activations of mTOR and ERK1/2.
