ABSTRACT
Type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) are the most problematic metabolic diseases in the world. NAFLD encompasses a spectrum of severity, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis, increasing the risk of cirrhosis and hepatocellular carcinoma. Importantly, NAFLD is closely linked to obesity and tightly interrelated with insulin resistance and T2DM. T2DM and NAFLD (T2DM-NAFLD) are called as the Xike Rixijing Disease and Tonglaga Indigestion Disease respectively, in Mongolian medicine. Xike Rixijing Disease maybe develop into Tonglaga Indigestion Disease. Forturnately many Mongolian medicines show efficient treatment of T2DM-NAFLD, such as Agriophyllum squarrosum, Haliyasu (dried powder of camel placenta), Digeda-4 (herbs of Lomatogonium carinthiacum, rhizomata of Coptis chinensis, ripe fruits of Gardenia jasminoides, herbs of Dianthus superbus), Guangmingyan Siwei Decoction Powder (Halite, ripe fruits of Terminalia chebula, rhizomata of Zingiber officinale, fruit clusters of Piper longum), Tonglaga-5 (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius), Tegexidegeqi (rhizomata of Inula helenium, ripe fruits of Gardenia jasminoides, rhizomata of Platycodon grandiflorum, rhizomata of Coptis chinensis, heartwood of Caesalpinia sappan), Ligan Shiliu Bawei San (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius, ripe fruits of Amomum tsao-ko, rhizomata of Zingiber officinale), etc. Principles of Mongolian medicine in treating diseases: by balancing “three essences or roots” and “seven elements”, strengthening liver and kidney function, transporting nutrients to enhance physical strength and disease resistance, and combined with drugs for comprehensive conditioning treatment. However, their molecular mechanisms remain unclear. In this review, we prospect that Mongolian medicines might be a promising treatment for T2DM-NAFLD by activating P2X7R/NLRP3/NF-κB inflammatory pathway via lipid-sensitive nuclear receptors (i.e., FXR and LXR).
ABSTRACT
Objective@#To explore the time and genotype distribution of human enterovirus (HEV) isolated from sewage in Shanghai in 2013-2014.@*Methods@#One sewage sample each was collected from two local sewage plants located in Minhang District and Jiading District on the same day at the day 24-28 of every month from 2013 to 2014. Each sample weighed 1 L. The specimens were concentrated by anionic membrane absorption, eluted with beef extract solution, and then used to inoculate RD, HEp-2, and L20B cell lines. A total of 249 enterovirus strains were isolated from sewage samples during the study period, including 185 non-polio enterovirus (NPEV) and 64 poliovirus (PV) strains, which were identified as vaccine strains. RT-PCR and Sanger sequencing were performed to identify HEV genotypes. Homologous analysis of VP1 sequences was conducted using BioEdit (version 7.0.0). Phylogenetic analysis was performed using the neighbor-joining method based on the alignment of VP1 gene sequences using MEGA (version 4.0.2).@*Results@#Among 185 NPEV strains, 178 strains were successfully sequenced and classified into 15 genotypes, including coxsackievirus group B (CVB) 2, 3, and 5; enteric cytopathic human orphan (ECHO) virus 1, 3, 6, 7, 11, 13, 19, 20, 24, 25, and 30; and coxsackievirus group A 4. CVB5 and ECHO6 genotypes accounted for 33.5% (56 strains) and 24.9% (43 strains) of NPEV isolates, respectively. During the study period, HEV isolates were mainly isolated in summer and autumn in Minhang District. ECHO6 strains were frequently isolated from June 2013 to July 2014. Thereafter, the number of ECHO6 strains gradually reduced in the second half of 2014. CVB5 strains demonstrated scattered distribution from 2013 to the first half of 2014 and gradually increased in the second half of 2014. The distribution of ECHO6 and CVB5 strains in Jiading District was similar to that in Minhang District. In 2013-2014, CVB5 strains comprised C6 and C8 subgenotypes, which belong to two transmission chains and show large differences compared with foreign strains isolated during the same period. ECHO6 strains comprised C6, C8, and D9 subgenotypes, which belong to three transmission chains. Moreover, ECHO6 subgenotype D9 was a dominant subgenotype in Shanghai, with broad geographical distribution both at home and abroad.@*Conclusion@#Poliovirus was identified as a vaccine strain in environmental surveillance from June 2013 to April 2014 in Shanghai. Several transmission strains of ECHO6 and CVB5 were identified, which were the dominant serotypes.
ABSTRACT
OBJECTIVE:To study the improvement effect and mechanism of Meng medicine Wuwei Shaji powder(WSP)on smoke-induced lung inflammation injury in mice. METHODS:ICR mice were randomly divided into blank group(normal saline), model group (normal saline) and WSP group (2 g/kg). Mice in model group and WSP group received passive smoking to induce model of lung inflammation injury,and intragastrically administrated relevant medicine when modeling,once a day,for 28 d. Af-ter administration,enzyme-linked immunosorbent assay was used to detect the tumor necrosis factor α(TNF-α),interleukin-1β(IL-1β),IL-6,IL-10 levels in bronchoalveolar lavage fluids(BALF);the pathological changes of lung tissue were observed by op-tical microscope after hematoxylin-eosin staining;Western blot was adopted to detect the protein expressions of extracellular sig-nal-regulated kinase (ERK1/2),phosphorylated ERK1/2 (p-ERK1/2),p38 mitogen-activated protein kinase (p38 MAPK),phos-phorylated p38 MAPK(p-p38 MAPK),nuclear factor kappaB p65(NF-κB p65)and phosphorylated NF-κB p65(p-NF-κB p65)in lung tissue of mice. RESULTS:Compared with blank group,TNF-α,IL-1β,IL-6 levels in BALF in model group were obviously increased (P<0.01);lung tissue showed significant inflammatory lesions;and the protein expressions of p-ERK1/2, p-p38 MAPK,p-NF-κB p65 in lung tissue were obviously increased (P<0.01). Compared with model group,TNF-α,IL-1β levels in BALF in WSP group were obviously decreased(P<0.05);inflammation injury in lung tissue was obviously improved;and protein expressions of p-p38 MAPK and p-NF-κB p65 in lung tissue were obviously decreased (P<0.05). CONCLUSIONS:WSP shows improvement effect on smoke-induced lung inflammation injury in mice,which might be by blocking the p38 MAPK,NF-κB p65 phosphorycation to inhibit the high expression of inflammatory factors as TNF-αand IL-6.
ABSTRACT
In this research project, rats were made into animal models of acute focal cerebral ischemia and reperfusion (IR) by occlusion of their middle cerebral artery (MCAO). We observed the effect of endogenous endothelial progenitor cells (EPCs) and serum cytokines on cerebral ischemia rats treated by electro-acupuncture(EA). The results showed: MCAO model had high stability after EA treatment which was delivered via the acupuncture needles inserted into "quchi" and "zusanli" points, the nervous functions of cerebral IR rats recovered faster than those of rats not treated; EPCs in rats' blood increased after acute focal cerebral ischemia and reperfusion; and the growth rate was obvious in IR group. This phenomenon might be related to the inflammation elicited by injury of ischemia and self-repair. Besides, EA treatment could decrease induced nitric oxide synthase (iNOS) activity, alleviate injury after cerebral ischemia, and regulate the quantity of EPCs in blood. The quantity of EPCs in blood increased in IR-24hr. In IR-48 hr, the rise of EPCs quantity was significant (P < 0.01). The level of vascular endothelium growth factor (VEGF) in serum of rats after cerebral ischemia was escalated, which indicated to a certain extent that cerebral ischemia could stimulate stress reaction. EA treatment could raise VEGF level, which suggested that high expression of VEGF could accelerate mobilization, chemotaxis and homing of EPCs. At the same time, the levels of matrix metalloproteinase-9 (MMP-9) and basic fibroblast growth factor (bFGF) also changed. In conclusion, EA treatment could promote neovascularization after cerebral ischemia by mobilizing EPCs, decreasing iNOS activity and increasing VEGF level. This may be one of the ways by which EA could treat cerebral ischemia.

The change of hemodynamics and hemorrheology induced by hypoxia challenge in the dog were investigated. The results showed that hypoxia caused significant decrease of cardiac output,increased pulmonary artery pressure and pulmonary vascular resistance. Hypoxia also caused increase of blood viscosity. In terms of changes of the reduced viscosity is directly related to the deformation and agglutination properties of red blood cells.
