Acidic electrolyzed water (AEW) ice is a novel technique for prolonging the shelf life of foods, but there is limited knowledge of its preservation mechanism. A proteomics approach and 16S rRNA-based Illumina sequencing were employed to investigate the changes of key proteins and bacterial communities in shrimp stored in AEW ice and tap water ice (TW ice) for 7 days. Compared with TW ice, AEW ice markedly retards the degradation of myofibrillar proteins in shrimp, including myosin, actin, and tropomyosin.

The objective of this paper was to investigate the effects of acidic electrolysed water (AEW) technology on polyphenoloxidase (PPO), which is an essential enzyme for browning.
Results: AEW ice exhibited a good ability in delaying browning in shrimp.
Background: Studies have shown a recent upsurge in human immunodeficiency virus (HIV) burden among men who have sex with men (MSM) in China, especially in urban areas. For intervention planning and resource allocation, spatial analyses of HIV/AIDS case-clusters were required to identify epidemic foci and trends among MSM in China.
Methods: Information regarding MSM recorded as HIV/AIDS cases during 2006-2015 were extracted from the National Case Reporting System.
Objectives: To explore models to improve HIV testing, linkage to care and treatment among men who have sex with men (MSM) in cooperation with community-based organizations (CBOs) in China.
Methods: We introduced a new model for HIV testing services targeting MSM in six cities in 2013.These models introduced provision of rapid HIV testing by CBO staff and streamlined processes for HIV screening, confirmation of initial reactive screening results, and linkage to care among diagnosed people.
Dearth of information regarding the trend and correlates of HIV, syphilis and Hepatitis C (HCV) in a country-wide sample of understudied though high-risk Chinese men who have sex with men (MSM) called for a comprehensive serial cross-sectional study. Using a multistage mixed-method strategy, 171,311 MSM from 107 selected cities/counties in 30 provinces of mainland China, were interviewed and tested. Descriptive, bivariate, multivariate and Cochran-Armitage trend analyses were conducted using SAS 9.

We implemented partner notification among HIV-infected MSM, cooperating with MSM-serving community-based organizations (CBOs) in two Chinese cities from June 2014 to May 2015. CBOs participated in identifying new HIV-positive MSM utilizing rapid HIV tests and partner notification among index cases.

Objective: To conduct a cost utility study on the HIV/AIDS 'one-stop service' at county level.
Methods: Financial records and questionnaires were used to collect the information about the resource allocation and the effectiveness of antivirus treatment (ART) during the two period which were January 2012-June 2013 and July 2013-December 2013 in the three pilot counties providing 'one-stop service'. Treeage Pro 2009 was used to build the Markov model to simulate the evolution of 5 different HIV statuses, including HIV infection, AIDS, HIV infection receiving ART, AIDS receiving ART and death.
Objective: To conduct health economic evaluation of the prevention of mother-to-child HIV among pregnant women in Dehong prefecture, Yunnan province, China from 2004 to 2013.
Methods: Data on cost were collected mainly from the annual prevention of mother-to-child transmission (PMTCT) reporting system of Dehong prefecture, and supplemented by HIV PMTCT-related resource allocation data from local health bureau. Effectiveness indexes were from local continuous HIV surveillance system and annual reported data.
During the past over 20 years of AIDS response in China, different fields from the international society and domestic sources provide significant amounts of resources for China's AIDS response. The investment, distribution and use of these resources and their effect has become the concern of the society. The health economic evaluation method is used to scientifically answer these questions, which is also the motivation of the evaluation studies.
