In this review, the characteristics of gut microbiota changes in 11 metabolic diseases, as well as the research progress on their interventions, are summarized. The gut microbiota contributes to metabolic diseases through intestinal mucosal dysfunction, chronic metabolic inflammatory response, gut brain axis imbalance, gene regulation, insulin resistance, and the action of its metabolites. The researches of cause effect relationship and mechanism are relatively few, need further study, expecting a breakthrough in the future to be a new path in the treatment of some metabolic diseases.

HIV-associated neurocognitive disorders (HAND) are chronic complications of HIV infection in the central nervous system. Clinical presentations include asymptomatic neurocognitive impairment (ANI), mild neurocognitive impairment (MND), and HIV-associated dementia (HAD). In the era of combination antiretroviral therapy (cART), the prevalence of HAD has significantly decreased, but the rates of ANI and MND have increased, impairing patients’ daily functioning, medical adherence, employment, driving abilities, risk of HIV transmission, overall quality of life, and posing challenges to society, economy, families, and public health. This article reviews the latest research findings regarding the pathogenesis, clinical diagnosis and treatment, neuroimaging, and neuropsychological assessment of HAND, aiming to provide insights into the prevention and management of HAND.

The adsorption curves of carboxymethylated lignin(CML) and sodium lignosulfonate(SL) on calcium carbonate and iron(Ⅲ) oxide particles were determined by Quartz crystal microbalance(QCM),respectively. The results were as follows: When calcium carbonate was used as the adsorbate, the concentration of CML corresponding to saturated adsorption was 200 mg·kg and the saturated adsorption was 4.6797 mg·g. Similarly, for SL, the corresponding concentration was 500 mg·kg and the relevant saturated adsorption was 6.0522 mg·g. When iron(Ⅲ) oxide was used as the adsorbate, for CML, the adsorption capacity firstly increased and then decreased with the increase of the concentration but no saturation capacity appeared. For SL, its concentration under saturated adsorption was 500mg·kg and the saturated adsorption capacity was 3.4300 mg·g. For the comparison, the adsorption curves were also determined by the traditional ultraviolet spectrophotometry(UV) method. The result showed difference between determined adsorption under different concentrations by the two methods was small and the relative error was within ±10%. It proved that QCM was feasible to determine the adsorption capacity of water-soluble ligin derivatives on the surface of calcium carbonate and iron(Ⅲ)oxide particles. This method had a wider scope of application and was a simple, precise and effective method.

Effects of cationic cetyltrimethylammonium bromide(CTAB) on aggregation behaviors of sodium lignosulfonate(Na LS) in concentrated solutions were investigated by rheology, conductivity, zeta potential and surface tension measurements. Results showed the presence of CTAB led to increased aggregate effects and enhanced association networks due to intermolecular bridging caused by the formation of mixed aggregates containing Na LS hydrophobes and CTAB molecules at CTAB/Na LS mixing ratios(w/w) below 1:7. However, further additions of CTAB resulted in the progressive disruption of network structures due to electrostatic repulsion between aggregates. The above results also revealed stoichiometric mass ratio(SMR) of Na LS/CTAB system, where the hydrophobicity was strongest and to prepare colloidal spheres was feasible.

After the reform and opening up, especially in recent years. Dairy farming has a rapid development in our country, however, the dairy farming link in our country also is in a small scale, and dairy cows yield at lower levels, based on the present situation of dair farming in our country, This article mainly analysis the problems of dairy farming link, and puts torward the corresponding countermeasures and suggestions to solve these problems.
