Objective: To observe the therapeutic effect of Tangzhi decoction on type 2 diabetes mellitus (DM2) complicated with hyperlipidemia. Methods: One hundred and five cases of DM2 complicated with hyperlipidemia were randomly allocated to two groups: 32 cases treated with phenformin served as control group and 33 treated with phenformin and Tangzhi decoction as treatment group. The treatment course last 2 months. Results: The symptoms were improved, levels of fasting blood glucose (FBS), two-hour postprandial blood glucose (2 hPBG) and glycosylated hemoglobin (HbA1c), low-density lipid cholesterol (LDL-C), total cholesterol and triglycerides lowered and high-density lipid cholesterol (HDL-C) increased in treatment group. The total effective rate was 90.9%in treatment and 56.3 %in control group. The differences of the above indexes were significant in the two groups (P

Objective To establish a simple, efficient and low-cost method for the detection of Salmonella typhimurium carrying SSeC gene. Methods In this study, a nano-biosensor ( FAM-P/GO) was successfully established based on the noncovalent assembly of carboxy-fluorescein ( FAM)-labeled probe and graphene oxide ( GO) . The target gene at different concentrations and SSeC gene-harbored bacterium sam-ples were detected by the FAM-P/GO nano-biosensor to evaluate its sensitivity. The specificity of the estab-lished nano-biosensor was evaluated by using DNAs with mismatched base pairs and single-stranded DNAs ( ssDNAs) extracted from various species. Results The established strategy for SSeC gene detection showed a good linear range of 0. 05-1. 0 μmol/L (R2=0. 992 1) with a lower limit of 0. 05 μmol/L. Moreover, the lower detection limit for target bacterium samples was 103 CFU/ml and the fluorescence intensity increased linearly with the concentration from 103 CFU/ml to 108 CFU/ml. The signal-to-noise ( S/N) of the experi-mental group was much greater than that of the control group, which indicated that the establish method was highly specific. Conclusion The FAM-P/GO nano-biosensor was successfully established in this study, which provided a new and possible way for the rapid detection of Salmonella typhimurium harboring SSeC gene.

Objective: To study the effect of three different doses of propofol, midazolam and etomidate on short latency somatosensory evoked potential(SLSEP). Method:Ninety patients undergoing elective operation were randomly divided into 3 groups with 3 subgroups each,and propofol,midazolam,etomidate were administered by bolus injection at propofol 1.5,2,3mg/kg, midazolam 0.2,0.3,0.4mg/kg, etomidate 0.15,0.3,0.4mg/kg accordingly. SLSEP was recorded before,during and after injection. Result:Propofol did not significantly change the latencies of the subcortical N_(14),cortical N_(20) and central conduction time(CCT)N_(14)-N_(20),decreased the interwave amplitude N_(20)-P_(25)(P

Microglial surveillance plays an essential role in clearing misfolded proteins such as amyloid-beta, tau, and α-synuclein aggregates in neurodegenerative diseases. However, due to the complex structure and ambiguous pathogenic species of the misfolded proteins, a universal approach to remove the misfolded proteins remains unavailable. Here, we found that a polyphenol, α-mangostin, reprogrammed metabolism in the disease-associated microglia through shifting glycolysis to oxidative phosphorylation, which holistically rejuvenated microglial surveillance capacity to enhance microglial phagocytosis and autophagy-mediated degradation of multiple misfolded proteins. Nanoformulation of α-mangostin efficiently delivered α-mangostin to microglia, relieved the reactive status and rejuvenated the misfolded-proteins clearance capacity of microglia, which thus impressively relieved the neuropathological changes in both Alzheimer's disease and Parkinson's disease model mice. These findings provide direct evidences for the concept of rejuvenating microglial surveillance of multiple misfolded proteins through metabolic reprogramming, and demonstrate nanoformulated α-mangostin as a potential and universal therapy against neurodegenerative diseases.
