Lung and intestine combination therapy(LICT) is effective in the treatment of acute lung injury(ALI). In this study, the combination of Mahuang Decoction and Dachengqi Decoction(hereinafter referred to as the combination), a manifestation of LICT, was employed to explore the effect of nuclear factor kappaB(NF-κB)/nucleotide binding oligomerization domain-like receptors-3(NLRP3) pathway and alveolar macrophage activation on the lung inflammation in rats with ALI, for the purpose of elucidating the mechanism of LICT in treating ALI. After the modeling of ALI with limpolysaccharide(LPS, ip), rats were respectively given(ig) the combination at 10, 7.5, and 5 g·kg~(-1)(high-dose, medium-dose, and low-dose LICT groups, separately), once every 8 h for 3 times. Haematoxylin-eosin(HE) staining was used to observe the histopathological changes of lung tissue, followed by the scoring of inflammation. Immunohistochemistry was applied to detect alveolar macrophage activation, enzyme-linked immunosorbent assay(ELISA) was applied to detect the serum content of tumor necrosis factor-α(TNF-α) and interleukin-18(IL-18), Western blot was applied to detect the protein expression of phosphorylated-nuclear factor kappaB p65(p-NF-κB p65), nuclear factor kappaB p65(NF-κB p65), phosphorylated-inhibitor kappaB alpha(p-IκBα), inhibitor kappaB alpha(IκBα), and NLRP3 in lung tissue, and quantitative reverse transcription-PCR(qRT-PCR) was applied to detect the mRNA expression of TNF-α, IL-18, NLRP3, and NF-κB p65 in lung tissue. The results showed that LICT groups demonstrated lung injury relief, decrease in inflammation score, alleviation of alveolar macrophage activation, significant decline in serum content of inflammatory factors TNF-α and IL-18, and decrease of the protein expression of p-NF-κB p65/NF-κB p65, p-IκBα/IκBα, and NLRP3, and mRNA expression of TNF-α, IL-18, NLRP3, and NF-κB p65 in lung tissue. In summary, LICT has definite therapeutic effect on ALI. The mechanism is that it inhibits alveolar macrophage activation by suppressing NF-κB/NLRP3 signaling pathway, thereby reducing the activation and release of inflammatory factors and finally inhibiting inflammation.

To analyze the genetic characterization of epidemic rubella virus strains isolated in Liaoning from 2007-2012, a total of 145 rubella virus strains were isolated using Vero/Slam cell line from the patients' throat swabs during rubella outbreaks and sporadics cases in Liaoning Province from 2007 to 2012. Fragments of 945 nucleotides containing 1E gene from 145 rubella virus isolates were amplified by RT-PCR, the PCR products were sequenced and analyzed. Based on the 739 nucleotides of 1E gene, the phylogenetic trees were constructed with 32 WHO rubella reference strains of 13 genotypes downloaded from GenBank and 145 rubella virus strains. The results showed that the 145 rubella virus strains in 2007 -2012 belonged to genotype 1E, nucleotide acids and amino acids similarities were 97.2%-100.0% and 97.6%-100.0%, respectively. Compared to the 1E reference strains(Rvi/ Dezhou.CHN/02, RVi/MYS/01), the nucleotide acids and amino acids similarities were 96.6%-99.2% and 98.2%-100.0%, respectively except for one amino acid change (Val246-Ala246) of RVi/Shenyang. Liaoning. CHN/13.11/13, and Asp262-Asn262 of RVi/Shenyang. Liaoning. CHN/13.11/4 and RVi/Liaoyang. Liaoning. CHN/26. 11/2. there had no change found in the important antigenic epitope sites, the hemagglutination inhibition and neutralization epitopes of the other rubella viruses. All the 145 strains isolated had the same amino acid change (Leu338--Phe338) in E1 protein. These findings suggested that genotype 1E of rubella virus was the predominant genotype in Liaoning province. the rubella prevailed in recent six years was mainly caused by rubella viruses genotype 1E with multi-transmission routes.

Erbin, a member of Leucine-rich repeat and PDZ-containing protein family, was found to inhibit TGF-β-induced epithelial-mesenchymal transition (EMT) in our previous study. However, the mechanism of Erbin in regulating EMT is unclear. Semaphorin protein Sema4C, with PDZ binding site at C-terminal has been recognized as a positive regulator of EMT. Here, we aimed to examine the interaction between Erbin and Sema4C. HK2 cells were treated with TGF-β1, or transfected with Erbin and (or) Sema4C. Interaction of Erbin and Sema4C was identified by immunoprecipitation. RT-PCR was used to detect the expression of Erbin and Sema4C at mRNA level after transfection. The expression levels of Erbin, Sema4C, and markers of EMT were measured by using Western blotting or ELISA. After HK2 cells were stimulated with 10 ng/mL TGF-β1 for 72 h, the protein expression levels of Erbin and Sema4C were both up-regulated, and immunoprecipitation results showed Erbin interacted with Sema4C in HK2 cells both at endogenous and exogenous levels. Furthermore, overexpression of Sema4C suppressed E-cadherin, induced vimentin and promoted fibronectin secretion, indicating Sema4C promotes the process of EMT. However, HK2 cells overexpressing Erbin were resistant to Sema4C-induced EMT. In contrast, Erbin specific siRNA promoted EMT induced by Sema4C. Taken together, these results suggest that Erbin can interact with Sema4C, and co-expression of Erbin blocks the process of Sema4C-induced EMT.

ObjectiveTo investigate the effect of combined therapy of lung and intestine （Mahuangtang + Da Chengqitang） on lipopolysaccharide （LPS）-induced acute lung injury （ALI） in rats and its protective mechanism. MethodWistar rats were randomly divided into blank group， model group， low-， medium-， and high-dose groups with combined therapy of lung and intestine ， and dexamethasone group. LPS （10 mg·kg^-1） was given （ip） to induce ALI in rats. The general state of rats in each group was observed and recorded. The body temperature of rats in each group was recorded 0-8 h after modeling by means of anal temperature measurement. Serum and lung tissues were collected 24 h after modeling. Serum levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， interleukin-10 （IL-10）， and arginase-1 （Arg-1） were determined by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the protein levels of nuclear factor kappa B p65 （NF-κB p65）， phosphorylated NF-κB p65 （p-NF-κB p65）， NF-κB inhibitor α （IκBα）， and phosphorylated IκBα （p-IκBα） in lung tissues of rats. The levels of classically activated （M1） macrophage marker CD80 and IL-1β and macrophage markers F4/80 and IL-10 were detected by double immunofluorescence. ResultCompared with the blank group， the model group showed increased body temperature and thermal response index （TRI）， elevated serum levels of pro-inflammatory factor TNF-α and IL-1β and anti-inflammatory factor IL-10 （P<0.01）， up-regulated protein levels of p-NF-κB p65 and p-IκBα in lung tissues （P<0.01）， and increased levels of F4/80， CD80， and IL-1β in lung tissues （P<0.01）. Compared with the model group， the lung-intestine combined treatment groups and the dexamethasone group exhibited decreased body temperature and TRI in rats （P<0.01）， declined serum levels of inflammatory factor TNF-α and IL-1β （P<0.05， P<0.01）， elevated serum levels of anti-inflammatory factor IL-10 and Arg-1 （P<0.05， P<0.01）， down-regulated protein levels of p-NF-κB p65 and p-IκBα in lung tissues （P<0.05， P<0.01）， decreased levels of CD80 and IL-1β， and increased levels of IL-10 in lung tissues （P<0.01）， while the level of F4/80 was not significantly changed. ConclusionThe combined therapy of lung and intestine can obviously alleviate the fever and inflammatory state of ALI rats， and the mechanism may be related to the inhibition of NF-κB inflammatory pathway and the polarization of lung tissue macrophages to anti-inflammatory phenotype.

Objective To explore the nutritional efficacy of compound protein powder formulations from different sources. Methods Three groups of compound protein powder formulations were obtained through scientific blending using soy protein, whey protein and yeast protein as raw materials. The effects of the compound protein powders on nitrogen metabolism, serum biochemical indicators, and pathological changes of liver tissue and epididymal fat in rats were evaluated. Results Compared with the control (casein), the net protein utilization, biological evaluation, and protein efficacy ratio of the compound protein powders in rats were significantly improved, and the changes in these indicators in the formula with the highest whey protein content were most significant among all three formulas. The compound protein powders effectively increased the levels of albumin and globulin, while decreased the content of total cholesterol, indicating beneficial effects on improving immunity and controlling lipid metabolism, with the formula group 2 being the most effective among all three groups. The pathological examination showed that the three groups of protein powder did not have adverse effects on liver tissue and epididymal fat. Conclusion The present study demonstrates that the compound protein powder formulation has nutritional value, which suggests a potential of the application of the compound protein powder formulation in the elderly, and people with special nutritional needs, such as sports people.
