A new （8-hydroxyquinolin-2-yl）methylene picolinohydrazide derivative （L） has been successfully synthesized and characterized. The probe L displays high selectivity to Co^2＋ in CH3CN/HEPES （1：1, V/ V, 10 mmol.L^-1 pH=7.4） with a fluorescence ＂ON-OFF＂ response. The Co^2＋ ion recognition event possesses some distinct features including rapid response, high selectivity and sensitivity, good anti-interference ability and being applicable within a wide pH range. Based on job＇s plot and ESI-MS studies, the 1 ： 1 binding mode was proposed. The binding constant of L and Co2＋ is 1.63×10^8 L·mol^-1 and the detection limit is 1.15μmol·L^-1. Natural water samples experiments revealed that probe L can be potentially applied to the detection of Co^2＋ in real environment.

MgAl-NH3 LDHs (layered double hydroxides), ZnAl-LDHs and ZnAl-NH3 LDHs with different molar ratio of Al/ammonia were synthesized by co-precipitation method. The synthetic LDHs samples were characterized by XRD, FT-IR, TGA-DTG and SEM techniques and tested by Congo red method. In addition, after PVC (Poly vinyl chloride) and DOP (Dioctylphthalate) were added to LDHs, the thermal stability for PVC was characterized by TGA-DTG. The results indicated that LDHs intercalated with ammonia improved thermal stability for PVC significantly, MgAl-NH3 LDHs (Mg2+:Al3+: NH3·H2O = 3:1:0.5) and ZnAl-NH3 LDHs (Zn2+:Al3+:NH3·H2O=2:1:1.5) showed the best thermal stability for PVC, interlayered space of LDHs became larger by intercalating ammonia.

MgAl LDHs intercalated with CO(NH2)2, NH4Cl and NH3·H2O were prepared by co-precipitation and XRD, FT-IR, TGA-DTA and SEM techniques were employed for characterization. The results indicated that the layer-layer spacing of LDHs was enlarged by 0.169, 0.285 and 0.227 Åwith the intercalation of CO(NH2)2, NH+4 and NH3, separately. The effects on thermal stability and degradation behavior of synthesized LDHs where mole ratios of Mg/Al/urea = 3:1:1, Mg/Al/NH4Cl = 3:1:1.5 and Mg/Al/NH3·H2O = 3:1:0.5 were investigated by Congo Red Method and thermogravimetric analysis (TGA) from 25°C - 800°C under N2. The TGA and DTA results showed, by incorporating 5% MgAl-CO(NH2)2 LDH, the dehydrochlorination temperature of PVC composites is 12°C higher than MgAl-NH+4 and MgAl-NH3 LDHs. MgAl-NH3 LDH enhances the ending temperature of the first degradation stage of PVC composites by 8°C compared with MgAl LDH. The LDH intercalated with CO(NH2)2 is proved to be an effective thermal stabilizer for PVC processing.

The impact of the gut microbiota is not limited to the intestine, but its interaction with the host produces active metabolites, which can be transported by the blood circulation to play important roles in various parts of the body. Among them, short-chain fatty acids (SCFAs), as important active products of gut bacteria, have been shown to exert anti-inflammatory and immunomodulatory effects and can play active roles as signaling molecules in the development of various intestinal and extraintestinal diseases, such as inflammatory bowel disease, colon cancer, multiple sclerosis, hypertension, allergic airway disease, obesity, diabetes, kidney disease, rheumatoid arthritis, etc. In this way, modulation of the intestinal microbiota and metabolism-active substances has gradually become a popular therapeutic method for many diseases of organs beyond the gut. To find new therapeutic targets for major human health problems, this article reviews the research on SCFAs in extraintestinal diseases.
