Objective To investigate the effects of alcohol extract of bark and male flower of Eucommia ulmoides Oliv. on airway allergic inflammation induced by chicken ovalbumin (OVA) in mice; To explore its mechanism of action. Methods On day 0, day 7, mice were intraperitoneally injected OVA for sensitization, followed by nasal stimulation for 21 days to establish airway allergic inflammation mice models. The mice were divided into normal group, model group, alcohol extract of bark of Eucommia ulmoides Oliv. group, alcohol extract of male flower of Eucommia ulmoides Oliv.group,and Dexamethasone group.Each medication group was given relevant medicine for gavage. The lung tissue was embedded in HE and PAS dyeing, to observe the pathological changes of bronchus and surrounding lung. The levels of serum OVA-IgE, IL-4, IFN-γ and IL-13 were measured by ELISA. The expression of ICAM-1, VEGF, MMP9 and TIMP1 were detected by immunohistochemistry. Flow cytometry was used to detect the expression of Th17 cells in peripheral blood. The expressions of TNF-α and IL-6 mRNA in lung tissue were detected by RT-PCR. Results The model group showed changes of airway allergic inflammatory such as eosinophils and other inflammatory cell infiltration, bronchial spasm, and mucus secretion. Lung histopathology in alcohol extract of bark and male flower of Eucommia ulmoides Oliv.groups was improved significantly(P<0.05).Compared with the normal group, the levels of serum OVA-IgE, IL-4 and IL-13 increased in model group, while the level of IFN-γ decreased (P<0.05, P<0.01). The expressions of ICAM-1, VEGF and MMP9 increased, while the expression of TIMP1 decreased (P<0.01); peripheral blood IL-17+cells increased (P<0.01); the expressions of TNF-α and IL-6 mRNA increased. Compared with the model group, the levels of serum OVA-IgE, IL-4 and IL-13 decreased in alcohol extract of bark and male flower of Eucommia ulmoides Oliv. groups (P<0.05, P<0.01); the expressions of ICAM-1 and VEGF decreased (P<0.05, P<0.01); the expression of TIMP1 increased. Alcohol extract of bark and male flower of Eucommia ulmoides Oliv.could down-regulate IL-17+cells,reduce the expression of IL-6 mRNA(P<0.05,P<0.01). Alcohol extract of bark of Eucommia ulmoides Oliv. group could induce the secretion of IFN-γ (P<0.01), and down-regulate the expression of TNF-α mRNA(P<0.05).Alcohol extract of male flower of Eucommia ulmoides Oliv. group could significantly down-regulate the expression of MMP9 (P<0.05). Conclusion Alcohol extract of bark and male flower of Eucommia ulmoides Oliv.can induce the production of OVA-IgE,inhibit secretion of Th2 cytokines, inhibit the expression of adhesion molecules, depress Th17 cells, so as to inhibit the airway allergic inflammation.

The investigators isolated one yeast from China Huaimao sweet flour paste. The strain was identified into Citeromyces, and claimed being a new species. The strain was named as Ctieromyces baadingensis zhang sp. Nov., which differed markedly from Citeromyces matritensis in physiological and biochemical characteristics. Citeromyces baod-ingensis didn't ferment sucrose and raffinose, and assimilated galactose and cellobiose, and didn't assimilate galactose and ceflobiose. The G+C mol% was 48.5.

In order to demonstrate the taxonomic position of paramyxovirus Tianjin strain and explore its mechanism of pathogenesis. Bioinformatics methods were used to analyze the deduced amino acid sequences of NP, P, M, and L protein of Tianjin strain. Phylogenetic analysis based on NP, P, M, and L protein sequences demonstrated that Tianjin strain belonged to the genus Respirovirus, in the subfamily Paramyxovirinae and most likely a new genotype of Sendai virus. Sequence similarities comparisons indicated that Tianjin strain P protein was poorly conserved, sharing only 78.7%~91.9% amino acid identity with 6 known Sendai viruses, while L protein was the most conserved, having 96.0%~98.0% amino acid identity with other Sendai viruses. Multiple-sequence alignments of Tianjin strain NP, P, M, and L protein with those of 6 known Sendai viruses showed that Tianjin strain possessed a lot of unique amino acid substitutions in protein sequences, 15 in NP, 29 in P, 6 in M, and 29 in L. The presence of these unique amino acid substitutions suggests that Tianjin strain maybe has a significant difference in host or pathological characteristics from the known Sendai viruses.

Objective To explore the relationship between fluconazole resistance and expression of multidrug resistant protein genes,including CDR1,CDR2,MDRI.Methods The total RNA was extracted from fluconazole-resistant and -susceptible Candida albicans isolates,and cDNA was synthesized.The expression of CDR1,CDR2 and MDRl genes was then detected by quantitative real-time PCR.The?CT (threshold cycle) value was obtained by subtracting the CT value of 18S rRNA from that of the targeted gene.Results The?CT value of CDR2 was significantly lower in fluconazole-resistant isolates than in fluconazole- susceptible isolates (7.52?2.53 vs.9.28?3.15,t=2.367,P

Objective To investigate the correlation between specific features on contrast-enhanced CT and its clinical findings of adrenal tuberculosis so as to improve the diagnostic accuracy of the disease. Methods Contrast-enhanced CT features in 30 patients with documented adrenal tuberculosis were retrospectively evaluated blindly for the features of location,size,morphology,attenuation and enhancement patterns on CT images,and compared with clinical and pathological materials.Results The common CT manifestations were as follows:enlargement of the adrenal glands in all 30 cases(bilateral 90%,mfilateral 10%)including mass-like enlargement in 13 cases and enlargement but the contours preserved in 17 cases, heterogeneity(28 cases,93.3%),calcification(17 cases,56.7%),and low attenuation in the center with peripheral enhancement(16 cases,53.3%)of the lesions.After antituberculosis chemotherapy, 5 cases of enlarged adrenal glands decreased in size or returned to normal size and configuration,with disappearance of the central low attenuation and new appearance of dot-like calcification in 2 cases.Cochran Armitage trend test showed there was an increasing tendency of calcification rate with clinical duration(X~2= 7.47,P

Objective To analyze gene expression profiles of biopsy specimens from breast cancer patients who were treated with neoadjuvant chemotherapy(NAC) after biopsies, and to identify the genes which are closely associated with the efficacy of neoadjuvant chemotherapy with T/FAC [docetaxel(Taxotere), 5-fluorouracil, doxorubicin and cyclophosphamide] or T/FEC (Taxotere, 5-fluorouracil, epirubicin and cyclophosphamide) regimen.Methods We retrieved and collected gene expression profiles from publicly available databases.Four datasets, a total of 844 samples, were finally retained because all the patients had received a uniform neoadjuvant chemotherapy regimen.Response to neoadjuvant chemotherapy was categorized as a pathological complete response (pCR) or residual invasive cancer (RD).The differentially expressed genes (adjusted P-value<0.05) and therapeutic efficacy were analyzed and explored.Results After differential analysis, genes whose expressions were higher or lower in pCR group than in RD group were identified in each of the four datasets, respectively.There were 34 and 42 genes which were simultaneously more highly expressed or more lowly expressed in pCR group than in RD group in the four datasets.The unsupervised clustering, based on the 76 intersection genes, showed that the pCR specimens tended to form one cluster and the RD tended to form the other.Conclusion The seventy-six differentially expressed genes are associated with the efficacy of neoadjuvant chemotherapy and are likely to be novel predictive biomarkers for the efficacy of neoadjuvant chemotherapy.

ObjectiveTo observe the effect of comprehensive therapy on forearm extensor myotenositis.Methods72 cases were divided into two groups: a control group of 36 cases who were given routine treatment,and an experiment group of 36 cases who were given thermotherapy,computerized medium-frequency electrotherapy,physiotherapy,and ADL instruction,etc.After two courses,a simple grading score(for forearms) was used to assess the effect.ResultsOf the control group,22 cases were cured,10 remarkably effective,4 effective;of the experiment,30 cured,4 remarkably effective,2 effective(u=2.04, P<0.05).The difference of average score for forearms before and after the treatment were(6.58±3.17) points for the control and(8.19±3.55) for the experiment(t=2.03,P<0.05).The average days of cure were(5.60±2.54) d for the experiment group,shorter than those for the control(7.00±2.27) d(t=2.05,P<0.05).ConclusionComprehensive therapy is effective on forearm extensor myotenositis.
