A new poly(I:C)-decorated PLGA-PEG nanoparticle promotes Mycobacterium tuberculosis fusion protein to induce comprehensive immune responses in mice intranasally.

Protein-based subunit vaccine against tuberculosis (TB) is regarded as safer but with lower immunogenicity. To investigate effective adjuvant to improve the immunogenicity of TB subunit vaccine, we modified ploy(I:C) onto PLGA-PEG copolymer nanoparticle with polydopamine to produce a new nanoparticle adjuvant named "PLGA-PEG-poly(I:C)" (NP).

Synergism therapeutic and immunoregulatory effects of Albendazole + rAd-mIL-28B against Echinococcosis in experiment-infected mice with protoscoleces.

The metacestode stage of Echinococcus granulosus can cause cystic echinococcosis (CE), which still widely occurs around the world. Since the early 1970s, benzimidazoles have been shown to inhibit the growth of cysts and used to treat CE. However, benzimidazoles are still ineffective in 20%-40% of cases.

Characterization and Recombinant Genotypes of HIV-1 in Gansu Province, China.

It is important to monitor the diversity and evolution of HIV-1 genotypes, especially in some remote and undeveloped regions in China where the diversity and distribution of HIV-1 genotypes are not fully clear. To investigate the genotypes and distribution of HIV-1 in far Northwestern Gansu Province of China, we selected 220 HIV-1-positive plasma samples from the Center for Disease Control and Prevention (CDC) in Gansu from January 2016 to December 2018. The viral load of inclusion samples were over 1,000 copies per milliliter.

Nutrition and exercise interventions could ameliorate age-related cognitive decline: a meta-analysis of randomized controlled trials.

Objective: To evaluate the effect of nutrition combined physical exercise interventions on age-related cognitive decline by a systematic review and meta-analysis.

Methods: We searched 9 databases, including PubMed, EMbase, The Cochrane Library, Web of Science, Science Direct, China National Knowledge Infrastructure (CNKI), VIP Information, China Biological Medical Database (CBM) and Wanfang for studies published until the end of December 2019. The selected trials should meet the following criteria, study objects: healthy adults aged 65 and over with cognitive dysfunction or diagnosed as MCI, but not meet the diagnostic criteria for dementia as well as no restriction on follow-up time, race or gender.

Prevalence of Different Genotypes of HIV-1 in Injection Drug Users in China: A Systematic Review and Meta-Analysis.

Background: Since 1981, an increasing trend in HIV has been observed for transmission via injection drug users (IDUs), sexual transmission and mother-to-child transmission. The IDUs are blamed for early increases in HIV-positive cases in China.

Objective: HIV genotypes of IDUs were comprehensively analysed to trace the source and relationships of the AIDS epidemic in China.
