Objective To study the activation of TLRs/NF-κB signal pathway and production of different functional cytokines during invasive pulmonary aspergillosis( IPA) , in order to probe the pathogene-sis of IPA. Methods Mouse were randomly divided into normal, normal + inoculated with Aspergillus fumigatus( normal inoculation group), and immune suppression + inoculation with Aspergillus fumigatus (IPAmodel group) , the mouse were killed at different time points after inhaling Aspergillus fumigatus spores by nose. Removing the lung tissue in a sterile manner and making pathological section respectively, counting Aspergillus fumigatus colony, dynamiclly detecting the expression of TLR2, TLR4 mRNA, variation of NF-κB p65 protein, pro-inflammatory cytokines TNF-α, IL-1β and anti-inflammatory cytokines IL-10 levels in the lung tissue by RT-PCR and Western blot method during Aspergillus fumigatus infection in mouse. Results (1) When it's 72 h after inhaling Aspergillus fumigatus by nose, IPA model emerged severe lung tissue inflammation, and generated a large number of hyphae, meanwhile, burthen of Aspergillus fumigatus was higher than normal inoculation group at each time point. (2)Compared with the normal inoculation group, IPA group whose TLR2 mRNA was low expression at early stage of infection (24 h), and emerged high expression at late stage of infection (120 h, 144 h); and TLR4 mRNA has been at a state of low expression in the infection process; NF-κB p65 suddenly increased at early stage of infection(24 h) and then continued to decline. (3) After infected by Aspergillus fumigatus in normal mouse, proinflammatory cytokine TNF-α, IL-1β in lung exhibited high expression at the early stages of infection, and the highest expression levels appeared at 48 h or 72 h, then decreased and recovered to normal level. And the expression level of anti-inflammatory cytokine IL-10 rised at late stage of infection; The IP A mouse released a lot of anti-inflammatory cytokine IL-10 at early stage of infection, which significantly reduced at late stage, and released pro-inflammatory cyto-kines TNF-α, IL-1β at slow and low level. Conclusion The abnormal activation of TLRs/NF-β signaling pathway caused the loss of dynamic balance between pro-inflammatory cytokines and anti-inflammatory cytokines, leading to the occurrence and development of IPA.

The amino acid sequence of the fusion protein FP3 was measured by two types of LC-MS/MS and its primary structure was confirmed. After reduction and alkylation, the protein was digested with trypsin and glycosyl groups in glycopeptide were removed by PNGase F. The mixed peptides were separated by LC, then Q-TOF and Ion trap tandem mass spectrometry were used to measure b, y fragment ions of each peptide to analyze the amino acid sequence of fusion protein FP3. Seventy-six percent of full amino acid sequence of the fusion protein FP3 was measured by LC-ESI-Q-TOF with the remaining 24% completed by LC-ESI-Trap. As LC-MS and tandem mass spectrometry are rapid, sensitive, accurate to measure the protein amino acid sequence, they are important approach to structure analysis and identification of recombinant protein.

This study aims to perform a survey of genetic variation in neuraminidase (NA) gene of influenza A/H3N2 virus, as well as related resistance to NA inhibitors, in Qinghai Province of China, 2010 to 2012. Strains of influenza A/H3N2 isolated during an influenza survey from 2010 to 2012 in Qinghai were enrolled by random sampling. Viral RNA was extracted and amplified by RT-PCR. Purified PCR products were sequenced thereafter. Genetic analysis of nucleic acid and the derived amino acid sequences was performed by MEGA 4.0. Phylogenetic trees were also constructed. Strains isolated during 2010-2011 in this study clustered closely with World Health Organization (WHO) 2010-2012 reference vaccine strain A/Perth/16/2009 and 2008-2010 reference vaccine strain A/Brisbane/10/2007 on the phylogenetic tree, while the 2012 isolates were located on another branch. In analysis of derived amino acid sequences, the 2010 isolates mutated at K81T, the 2011 isolates mutated at I26V and D127N, while the 2012 isolates mutated at E41K, P46A, I58V, T71N, L81P, D93G, D127N, D151N, and I307M. The D151N mutation added a glycosylation site to the activity center of NA. No significant variation was discovered in H3N2 NA gene of 2010-2011 isolates in Qinghai, China. Isolates of 2012 were found with significant mutation, which has the potential of inducing minor resistance to NA inhibitors like zanamivir and oseltamivir.

OBJECTIVETo compare the therapeutic effect of Astragalus and Angelica Mixture (AAM) on treating CKD patients according to different CKD primary diseases, staging and TCM syndromes.

METHODSA multicentre, open-label, and self control clinical design was used, and thirty-two patients in line with inclusive criteria were recruited. Based on maintaining their previous basic CKD treatment, patients additionally took AAM (Astragalus and Angelica each 30 g), once a day, three months consisted of one therapeutic course. Serum creatinine (SCr), estimated glomerular filtration rate (eG- FR), 24 h urinary total protein (UTP), plasma albumin (ALB), hemoglobin (Hb), and changes of TCM syndrome factor integrals were compared before treatment, at the end of month 1, 2, and 3. The differences in the aforesaid indices were compared between CKD patients with different CKD primary diseases (chronic glomerulonephritis, chronic renal tubulointerstitial disease, hypertensive renal damage), different CKD stages (CKD 3 and CKD 4), and patients of qi-blood deficiency syndrome (QBDS) and non-QBDS.

RESULTSAAM could improve 78.12% (25/32) patients' renal function. Compared with before treatment, SCr decreased (12.08% +/- 10.11%), eGFR increased (21.14% +/- 18.55%), and ALB increased (2.76% +/- 1.97%) at the end of 3-month treatment (all P < 0.05). As for TCM syndrome factor integrals, compared with before treatment, the integrals for qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome decreased, while the integrals for dampness heat syndrome and turbid-toxin syndrome increased (all P < 0.05). There was no obvious difference in all indices except the integral for hypertensive renal damage patients of yin deficiency syndrome (P > 0.05). The SCr decreasing percent was 19.82% +/- 8.30% for patients of non-QBDS and 5.24% +/- 10.75% for patients of QBDS. The latter was higher with statistical difference (P < 0.05). As for TCM syndrome factor integrals, the integral differences of qi deficiency and blood deficiency were obviously higher in patients of QBDS, when compared with patients of non-QBDS (P < 0.05).

CONCLUSIONAAM could improve the renal function of CKD patients, elevate their ALB levels, and ameliorate associated qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome, especially for CKD patients of QBDS.
