It is important to pay more attention to students’ basic skills training and their comprehensive abilities cultivating in microbiology experiment teaching. Explorations and reforms in enforcing the students’ base and cultivating their abilities were carried out in order to improve teaching quality and train specialized talents with high quality.

0.05).3.Thirty-three point three percent of animals from parental strain group were found fibrillations potentials and the po-sitive sharp waves in gastrocnemius electromyogram,no obvious abnormal waves were found in animals from both waaF mutant and control group.Conclusions The ganglioside-like epitope in LOS of CJ is critical antigen in inducing GM1-IgG antibody and in inducing conduction block of peripheral nerve,therefore,provide a support for the molecular mimicry theory as a pathogenesis in the axonal GBS following CJ infection.

Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.

Ergosterol is the important component of the fungal membrane, and having stable structure. This makes it a suitable indicator for growth of fungi. In the paper, isolation and determination techniques of ergosterol as the indicator of the fungal biomass were reviewed. The methods of extracting ergosterol include traditional saponification and refluxing, rapid physical disruption, rapid ultrasonication, supercritical fluid extraction and so on. The ergosterol determination methods are high performance liquid chromatography, gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and thin-layer chromatography, et al. The application of these techniques was also introduced. Finally, the paper prospected the feasibility of applying the ergosterol as the indicator of fungal biomass in composting.

Background: Myocardial infarction (MI) is a major disease burden. Wild?type p53?induced phosphatase 1 (Wip1) has been studied extensively in the context of cancer and the regulation of different types of stem cells, but the role of Wip1 in cardiac adaptation to MI is unknown. We investigated the significance of Wip1 in a mouse model of MI. Methods:The study began in June 2014 and was completed in July 2016.We compared Wip1?knockout (Wip1?KO) mice and wild?type (WT) mice to determine changes in cardiac function and survival in response to MI. The heart weight/body weight (HW/BW) ratio and cardiac function were measured before MI. Mouse MI was established by ligating the left anterior descending (LAD) coronary artery under 1.5%isoflurane anesthesia.After MI, survival of the mice was observed for 4 weeks. Cardiac function was examined by echocardiography. The HW/BW ratio was analyzed, and cardiac hypertrophy was measured by wheat germ agglutinin staining. Hematoxylin and eosin (H&E) staining was used to determine the infarct size. Gene expression of interleukin?6 (IL?6), tumor necrosis factor?α (TNF-α), and interleukin?1β (IL-1β) was assessed by quantitative real?time polymerase chain reaction (qPCR), and the levels of signal transducers and activators of transcription 3 (stat3) and phosphor?stat3 (p?stat3) were also analyzed by Western blotting. Kaplan?Meier survival analysis, log?rank test, unpaired t?test, and one?way analysis of variance (ANOVA) were used for statistical analyses. Results: Wip1?KO mice had a marginally increased HW/BW ratio and slightly impaired cardiac function before LAD ligation. After MI, Wip1?deficient mice exhibited increased mortality (57.14% vs. 29.17%; n = 24 [WT], n = 35 [Wip1?KO], P < 0.05), increased cardiac hypertrophy (HW/BW ratio: 7 days: 7.25 ± 0.36 vs. 5.84 ± 0.18, n = 10, P < 0.01, and 4 weeks: 6.05 ± 0.17 vs. 5.87 ± 0.24, n = 10, P > 0.05;cross?sectional area: 7 days: 311.80 ± 8.29 vs. 268.90 ± 11.15, n = 6, P < 0.05, and 4 weeks: 308.80 ± 11.26 vs. 317.00 ± 13.55, n = 6, P > 0.05), and reduced cardiac function (ejection fraction: 7 days: 29.37 ± 1.38 vs. 34.72 ± 1.81, P < 0.05, and 4 weeks: 19.06 ± 2.07 vs. 26.37 ± 2.95, P < 0.05; fractional shortening: 7 days: 13.72 ± 0.71 vs. 16.50 ± 0.94, P < 0.05, and 4 weeks: 8.79 ± 1.00 vs. 12.48 ± 1.48, P < 0.05; n = 10 [WT], n = 15 [Wip1?KO]). H&E staining revealed a larger infarct size in Wip1?KO mice than in WT mice (34.79% ± 2.44% vs. 19.55% ± 1.48%, n = 6, P < 0.01). The expression of IL?6 and p?stat3 was downregulated in Wip1?KO mice (IL?6: 1.71 ± 0.27 vs. 4.46 ± 0.79, n = 6, P < 0.01; and p?stat3/stat3: 1.15 ± 0.15 vs. 1.97 ± 0.23, n = 6, P < 0.05). Conclusion: The results suggest that Wip1 could protect the heart from MI?induced ischemic injury.

AIMTo investigate the effects of Angelica sinensis polysaccharide fraction AP-3 on IL-2 and IFN-gamma induction and its further immunomodulatory feature.

METHODSThe percentage of CD4+ lymphocyte was detected by flow cytometric method, the production of IL-2 and IFN-gamma in cell culture supernatant were determined by ELISA, mRNA expressions of IL-2 and IFN-gamma cytokines were detected by RT-PCR.

RESULTSAt the range of 0. 6 - 2 micromol x L(-1), AP-3 significantly enhanced the percentage of CD4+ lymphocytes in total splenocytes. At the range of 2 - 6 micromol x L(-1), the treatment of AP-3 augmented both productions of IL-2 in cell culture supernatant and cell IL-2 mRNA transcription level in a time and dose dependent manner. While in the case of IFN-gamma, AP-3 stimulated at early time after exposure but down-regulated thereafter.

CONCLUSIONAngelica sinensis polysaccharide could regulate the immune response through upregulating IL-2, IFN-gamma expression and activating Th1 cell.

Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in assessment of left ventricular (LV) strains. Methods Thirty healthy young adults examined by two-dimensional speckle tracking imaging (2D-STI) and 3D-STI. And the results of LV measurements were compared, which included mean peak systolic longitudinal strains, radial strains and circumferential strains. Also, the time consumption of these two methods was compared. Results The time needed for 3D-STI in acquisition and analysis of the images were (309.3±23.4)s, (305.5±11.2)s, while the time for 2D-STI were (490.6±14.4)s, (1261.4±39.9)s. The differences were signiifcant(t=-21.81, 69.94, both P<0.01). The global mean peak systolic radial strains was (48.59±7.68)%by 3D-STI and (33.25±7.27)%by 2D-STI. The difference was signiifcant(t=9.16, P<0.01). The global mean peak systolic longitudinal and circumferential strains were (-17.66±3.14)%, (-17.13±2.29)% by 3D-STI and (-21.35±2.46)%, (-21.97±3.84)% by 2D-STI. The differences were signiifcant(t=5.33, 5.99, both P < 0.01). The 3D-STI strains were different at different levels of LV. The longitudinal, circumferential and radial 3D-STI strains were largest at middle levels. However, 2D-STI strains didn′ t show such trend. Peak strains measured by 3D-STI and 2D-STI showed high inter-observer and intra-observer agreement in Bland-Altman chart. Conclusion 3D-STI is a novel, convenient and reproducible method to evaluate the strains of LV.
