Objective Intercellular adhesion molecule-1 (ICAM-1) plays an important role in mediating pulmonary infiltration of neutrophils .The aim of the study was to observe the expression of ICAM-1 and its potential regulators MK 2/HuR in pulmonary micro-vascular endothelial cells ( PMVEC ) in mice with acute respiratory distress syndrome ( ARDS) induced by lipopolysaccharide ( LPS) . Methods Ten 6-8 weeks old healthy C57BL/6 mice were randomly divided into an LPS and a control group of equal number , the former injected intraperitoneally with LPS diluted in 100 μL PBS while the latter with PBS only , both at 5 mg per kg of the body weight .At 24 hours after injection , all the mice were sacrificed .Real-time PCR was used to determine the mRNA expressions of HuR and ICAM-1 in the PMVECs, Western bolt employed to detect the protein expressions of MK2, HuR and ICAM-1, and flow cytometry adopted to measure the ICAM-1 expression on the surface of the PMVECs and pulmonary infiltration of neutrophils . Results The W/D ratio in the lung tissue of the mice was significantly lower in the LPS than in the control group (3.61 ±0.28 vs 6.16 ±0.40, P<0.05), while the rate of neutrophil infiltration markedly higher in the former than in the latter ([13.92 ±3.23]%vs [3.24 ±1.24]%, P<0.05).The mRNA and protein expressions of ICAM-1 in the PMVECs were significantly elevated in the LPS group as compared with that in the control (P<0.05), and so was the mRNA expression of HuR (P<0.05).No remarkable changes were observed in the expressions of total MK 2 and HuR proteins, but phosphorylated MK2 (p-MK2) and cytoplasmic HuR were increased in the LPS-stimulated mice. Conclusion Specific blockage or reduction of the HuR expression in PMVECs may lower the expression of ICAM-1, reduce neutrophil infiltration , and lessen pathophysiological changes in mice with ARDS .

Objective To compare the difference of biochemical characteristics and virulent Pst Ⅰ of Yersinia pestis strains in traditional focuses of plague in Yunna Province and in the new focuses of plague in Yulong County. Methods The identification data of biochemical characteristics(Rhamnose, Glycerol, Maltose, L-Arabina and Melibiose fermentation) and virulence factor(Pst Ⅰ) from different focuses of plague in Yunna Province were Retrospectively collected by tube test followed by the analysis using statistics software SAS 8.0 by Fisher exact probability of disordered two-way R × C table χ2 test. Results Among 48 strains of Yersinia pestis from hantaan type plague focus, 1 strain fermented L-maltose, 48 strains fermented Glycerol. Among 165 strains of Yersinia pestis from the Soul type plague focus, 1 strain did not ferment L-maltose, only one of them fermented Glycerol. 1 strain from the Soul type plague focus was confirmed to have mutation, for the test of nitrate reduction reaction was negative. All 5 strains of Yersinia pestis from the new focuses of plague in Yulong County fermented L-maltose and Glycerol. The statistical result showed that the differences in L-maltose and Glycerol fermentation of Yersinia pestis from different natural focuses of plague in Yunnan Province were statistically siguificant (P < 0.01). The differences of other biochemical characteristics and Pst Ⅰ were not statistically significant (P > 0.01). Conclusions Biochemical characteristics of Yersinia pestis from the hantaan type plague focus and the Soul type plague focus in Yunnan province are overlapping. Biochemical characteristics of Yersinia pestis from the new focuses of plague in Yulong County are different from those tradition focuses of plague in Yunna Province but share similarities to those from Unquiculatus focuses in North Tibet.

OBJECTIVETo observe the effect of naringin of Drynaria Rhizome, a Chinese medical component of Zhuanggu Jianxi Recipe (ZJR) containing serum on caveolin-p38MAPK signal factors (such as caveolin-1, p-p38, p-ATF-2, IL-1β, and TNF-α) in IL-1β induced rabbit degenerated chondrocytes, and further to explore its mechanism for protecting articular cartilages.

METHODSNaringin of Drynaria Rhizome was obtained and analyzed by HPLC-TOF/MS. Four weeks old New Zealand rabbits were killed and their bilateral knee joints were isolated aseptically. CDs were isolated and then cultured in vitro. The second generation of CDs were used for later experiment. The effect of naringin on CDs proliferation was detected by MTT assay. The effect of naringin on the expression of IL-1β-induced collagen II in CDs was detected by immunohistochemical method. The effect of naringin on caveolin-1, p-p38, and p-ATF-2 protein in IL-1β-induced CDs was detected by Western blot. The effect of naringin on mRNA expression of IL-1β and TNF-α in IL-1β-induced CDs was detected by RT-PCR.

RESULTSThe appearance time of naringin in flow graphs of naringin standard solution and ZJR containing serum was 23.5 min, and the molecular weight ranged between 581.0 and 581.5 m/z. Naringin could promote the proliferation of CDs, and inhibit the effect of IL-1β on collagen II in CDs. Compared with the model group, naringin could reduce the expression of caveolin-1, p-p38, p-ATF-2, IL-1β, and TNF-α in IL-1β induced CDs (P < 0.05), which was approximate to the level of the normal group.

CONCLUSIONSNaringin could not only promote the proliferation of CDs, but also protect IL-1β-induced CDs. Its mechanism might be associated with decreasing the expression of caveolin-1, p-p38, and p-ATF-2 proteins, inhibiting caveolin-p38MAPK signal pathway, and further reducing mRNA expression of IL-1β and TNF-α in the downstream of caveolin-p38MAPK signal pathway.

OBJECTIVETo investigate the optimum phase and dose of pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) on the differentiation and mineralization of osteoblast (OB). METHODS (OB) was isolated from the skull of 10 newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion. After the OB was identified, different kinds of pharmaco-serum of diabetic rats fed with inactive Qianggubao decoction ([Chinese characters: see text]) of different phase (rats were fed with medicine three days or five days after last fed with medicine one hour or three hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After 7 days and 18 days of culture,the effects of the differentiation and mineralization of osteoblast were detected.

RESULTSThe secretion of ALP and formation of mineralized nodules of osteoblast in the different doses of pharmaco-serum groups were almost the same as that of normal control group, but were superior to that in the model control group. And the group with concentration of 20% pharmaco-serum was the best in the secretion of ALP and formation of mineralized nodules of osteoblast. As to the phases of pharmaco-serum, the best one on the differentiation and mineralization of osteoblast was the serums from diabetic rat-model fed with Qianggubao decoction ([Chinese characters: see text]) three days or five days, after one hour of last fed with medicine.

CONCLUSIONThe pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) can promote the differentiation and mineralization of osteoblast. Allow for time and the cost of experiment,we presume that pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) three days, after one hour of last fed, with concentration of 20% and not-inactivation is the optimum on the differentiation and mineralization of osteoblast.

OBJECTIVETo investigate the association of single nucleotide polymorphisms (SNPs) in the interleukin 17 (IL-17) gene and serum protein levels in patients with chronic hepatitis C virus (HCV) infection.

METHODSA total of 228 patients with chronic HCV infection and 81 healthy controls were enrolled in the study. The frequencies of IL-17 rs8193036 and rs2275913 polymorphisms were detected by the TaqMan SNP genotyping assay. Serum levels of IL-17 protein were detected by ELISA. Pairwise comparisons were made by the Chi-square test, and the significance of between-group differences was assessed by the Student's t-test with P less than 0.05.

RESULTSThe patients with chronic HCV infection and the healthy controls showed similar frequencies of the rs8193036 C/T allele (x2 = 1.428, P = 0.232) and the rs2275913 A/G allele (x2 = 0.106, P = 0.744). In addition, the two groups showed similar distribution of the rs8193036 CC (chronic HCV infection: 46.49% vs. healthy controls: 41.98%), CT (45.61% vs. 44.44%) and TT (7.89% vs. 13.58%) genotypes (x2 = 2.346, P = 0.309), and of the rs2275913 AA (16.23% vs. 13.58%), AG (48.25% vs. 50.62%) and GG (35.53% vs. 35.80%) genotypes (x2 = 0.340, P = 0.844). Subgroup analysis of chronic HCV infection patients stratified according to HCV genotypes 1 and 2 showed no differences in the distribution of rs8193036 and rs2275913 alleles (x2 = 1.127, P = 0.288; x2 = 1.088, P = 0.297) and genotypes (x2 = 2.825, P = 0.246; x2 = 0.970, P = 0.616). However, the chronic HCV infection group did show significantly higher levels of serum IL-17 than the controls (97.67+/-39.68 vs. 71.60+/-19.78 pg/ml, t = 2.414, P = 0.033).

CONCLUSIONChronic HCV infection is associated with increased serum IL-17; however, the IL-17 polymorphisms rs8193036 and rs2275913 were not associated with chronic HCV infection susceptibility in this study's Chinese cohort.

OBJECTIVETo evaluate the effect of Zhuanggu Jianxi Decoction (, ZGJXD) on interleukin-1 β (IL-1 β)-induced degeneration of chondrocytes (CDs) as well as the activation of caveolin-p38 mitogen-activated protein kinase (MAPK) signal pathway, investigating the possible molecular mechanism that ZGJXD treats osteoarthritis.

METHODSSerum pharmacology was applied in the present study, where ZGJXD was orally administrated to New Zealand rabbits and then ZGJXD containing serum (ZGJXD-S) was collected for following in vitro experiments. CDs were isolated aseptically from New Zealand rabbits and then cultured in vitro. Upon IL-1 β stimulation, the degeneration of CDs was verified by inverted microscope, toluidine blue stain and type II collagen immunocytochemistry. After IL-1 β-stimulated CDs were intervened with blank control serum, ZGJXD-S, together with or without SB203580 (a specific inhibitor of p38 MAPK) for 48 h, caveolin-1 protein expression and the phosphorylation level of p38 were determined by Western blotting, and the mRNA expression of IL-1 β, tumor necrosis factor α (TNF-α), matrix metalloproteinase 3 (MMP-3) and MMP-13 were examined by real-time polymerase chain reaction.

RESULTSIL-1 β stimulation induced degeneration of CDs, increased caveolin-1 expression and p38 phosphorylation, up-regulated the mRNA level of IL-1 β, TNF-α, MMP-3 and MMP-13. However, the IL-1 β-induced activation of caveolin-p38 signaling and alteration in the expression of p38 downstream target genes were suppressed by ZGJXD-S and/or SB203580 in CDs.

CONCLUSIONZGJXD can prevent CDs degeneration via inhibition of caveolin-p38 MAPK signal pathway, which might be one of the mechanisms that ZGJXD treats osteoarthritis.
