Network pharmacology and in vitro study of Fengreqing oral liquid in the intervention of wind-heat pattern.

Objective: To investigate the underlying mechanism of the effect of Fengreqing oral liquid (, FOL) on wind-heat pattern (WHP).

Methods: In this study, we predicted the potential targets of FOL via the approach of network pharmacology and verified it by in vitro inflammation model. In the network pharmacology part, two strategies, namely the direct target search and the indirect one, were used to collect the target sets of FOL in WHP treatment.

[Investigation of Lentiviral Vectors Based Integrin β8 RNAi System in Neonatal Rats' Brain].

Objective: To construct lentiviral vectors expressing pSicoR- shRNA and evaluate its efficiency of RNA interference in neonatal rats' brain.

Methods: Plasmid vectors pSicoR- shRNA and pSicoR-control,as well as lentiviral packaging system and were amplified respectively and plasmid DNA was identified by restriction enzyme digestion. Lentiviral packaging system and expressing vector pSicoR- shRNA/pSicoR-control were co-transfected into packaging cell line 293T.

[Comparison of soil heavy metals determined by AAS/AFS and portable X-ray fluorescence analysis].

Total concentrations of Cu, Pb, As, Cr, Ni and Zn were determined for 53 soil samples using portable X-ray fluorescence (PXRF) system in in-situ and ex-situ (Lab.) conditions. PXRF metal concentrations were statistically compared with analytical results from traditional AAS/AFS analysis.

[Effects of long-term manure and crop residues incorporation on yield and phosphorus saturation in a paddy soil].

An 8-year field experiment was conducted in the Taihu Lake region of eastern China to investigate the effects of incorporation of straw and manure on the yield and phosphorus (P) accumulation in the paddy soil, and to evaluate the potential risk of P loss from soil to environment. The experiment had four fertilization treatments, i. e.

[Comparing the ammonia volatilization characteristic of two typical paddy soil with total wheat straw returning in Taihu Lake region].

An experiment using monolith lysimeter was conducted to compare the characteristic of N loss by ammonia (NH3) volatilization between the gleyed paddy soil (G soil) and hydromorphic paddy soil (H soil) the Changshu National Agro-ecological Experimental Station of the Chinese Academy of Sciences(31 degrees 33' N, 123 degrees 38' E). Three treatments were designed for each soil type, i. e.

4-(2,4-Dichloro-phen-yl)-5,5-dimethyl-2-(3-silatranyl-propyl-mino)-1,3,2-dioxa-phospho-rinane 2-oxide.

In the title compound, C(20)H(31)Cl(2)N(2)O(6)PSi, the dioxaphospho-rinane ring adopts a cis conformation. The silatrane fragment forms a cage-like structure in which there exists an intra-molecular Si-N donor-acceptor bond. In the crystal, centrosymmetrically related mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into inversion dimers, generating rings with graph-set motif R(2) (2)(8).

[Effect of ginsenoside Rg1 on angiogenesis after neonatal hypoxia ischemia brain damage in rats].

Objective: To investigate effects of ginsenoside Rg1 on angiogenesis in neonatal rats with hypoxia ischemia brain damage (HIBD), and explore the possible mechanism.

Methods: Fifty-four of 10-day-old SD rats were randomly divided into sham-operation group (n = 6), hypoxia-ischemia brain damage group (n = 24) and ginsenoside Rg1 treatment group (n = 24). SD rats in HIBD group and Rg1 group were treated by separation and ligation of right common carotid artery (CCA) and subsequently exposed to hypoxia for 2.
