Objective To evaluate the effect of perioperative enteral immunotrition(IMPACT) on liver regeneration in cirrhotic rats with hepatectomy. Methods Forty-eight cirrhotic rats were randomly divided into two groups: Group A, perioperative standard enteral nutrition group(n=24), receiving standard enteral nutrient NUTRISON during hepatectomy. Group B, perioperative enteral immunonutrition group(n=24), receiving enteral immunonutrient IMPACT after hepatectomy. According to the different time of taking specimens, each group was separated into four subgroups, each subgroup had six rats. The rats in the two groups received equal daily nutritional supplement intragastrically, which was 690kJ/kg per day. Before the 68% hepatectomy, the rats were fed with enteral nutrient for 8 days, and after operation were fed until the day of taking specimens. On the day before hepatectomy and 1st, 4th and 8th postoperative day(POD), MI (mitotic index) of liver cell and PCNA (proliferating cell nuclear antigen) labeling index of hepatocyte were determined. Results MI increased significantly in both group on 4th and 8th postoperative day(P

Bone marrow stromal antigen 2 (BST-2) is a kind of host restriction factor. Since it was discovered to be responsible for the defect in virion release of HIV-1 mutants lacking the accessory gene vpu in 2008, it was thought to mainly restrict the viruses by directly tethering viral particles at the plasma membrane. Recent reports suggest that BST-2 also can inhibit the the release of HBV particles, which are budding in the intracellular vesicles, expanding the antiviral spectrum of BST-2. Futhermore, the machanism that BST-2 used to restrict HBV release in multivesicular bodies (MVBs) is similar to that used to restrict HIV at the plasma membrane. However, HBV have evolved strategies to antagonize the antiviral action of BST-2. There are two different opinions about the antagonist. One is HBV inactivated BST-2 by HBx requiring a hepatocyte-specific environment. Another thought envelope protein HBs counteract the antiviral action of BST-2. In this review, we focus on the current advances in the anti-HBV activity of BST-2.

A safe and effective vaccine against the human immunodeficiency virus type 1 (HIV-1) is expected to have a considerable impact on elimination of acquired immune deficiency syndrome. Despite decades of effort, an effective vaccine against HIV-1 remains elusive. In recent years, the Thai HIV Vaccine Efficacy Trial (known as RV144) showed a reduction in HIV-1 acquisition by 31%, but this agent could not delay disease progression in vaccinated individuals. Clinical analyses of experimental data and experiments in vitro have revealed two main types of immunogen design: induction of broad-spectrum neutralizing antibody (bNAb) and cytotoxic T lymphocyte (CTL) responses. bNAb can prevent or reduce acquisition of infection, and its main immunogens are virus-like particles, natural envelope trimers and stable bNAb epitopes. An effective CTL response can slow-down viral infection, and its main immunogens are "mosaic" vaccines, "conserved immunogens", and the "fitness landscape" of HIV-1 proteins. This review summarizes the strategies as well as progress in the design and testing of HIV-1 immunogens to elicit bNAb and CTL responses.
