Objective Through isolating the histidine kin ase gene of Aspergillus fumigatus,to detect its role in the invasive aspergillosis.Methods Using degenerate primers for highly conserved regions of his-tidine kinase,RT -PCR was performed with cDNA of Aspergillus fumigatus as a template.The gene expression of it in vitro and in vivo was investig ated by Northern blot.Results A fragment of this gene was cloned fro m Aspergillus fumigatus that is highly homologous to tesA gene of Aspergillus nidulans,which was expressed at high level during invasive infection.Conclusion The results indicate that this gene may attribute to the invasive aspergillosis.

Objective To establish a qualitative and quanti ta tive method with RP-HPLC for controlling the quality of Cortex Moutan. Methods The experimental conditions of the RP-HPLC method wer e as follows: planetsil C 18 column (150 mm?4.6 mm, 5 ?m), mobile phase of methanol-water-acetic acid ( 44∶56∶0.1), flow rate at 1.0 mL?min -1, detection wavelength at 240 nm and room temperature. The qualitative fingerprint of Cortex Moutan and the quantitative measurement of paeonol wer e carried out under the chromatographic conditions mentioned above. Res ults Eleven comparatively stable peaks were detected among 13 differ ent samples, from which 10 common peaks used as index peaks for qualitative iden tification were conformed by correlating the peak areas. At the same time, the c ontents of paeonol in samples range from 1.32% to 2.78%. Conclusion The analytical method with qualitative fingerprint of Cortex Moutan and quantitative measurement of paeonol can effectively be used to control the quality of Cortex Moutan.

Objective To investigate the efficacy of microsurgery treatment with small craniotomy lateral fissure approach for hyperten-sive basal ganglia intracranial hemorrhage. Methods From December 2013 to February 2015, 30 patients with hypertensive basal ganglia intracranial hemorrhage ( blood loss within 30~60 mL) were analyzed respectively. Summarized the methods and techniques of this microsur-gery treatment and analyzed its advantages and disadvantages compared with the traditional operation. Results The hematomas were excluded more than 90% which were proved by reexamination after opreation. There was one case of temporal lobe infarction,but there was no re-bleed case and death case. The recovery of consciousness is good, and the limb function and language function were improved by early rehabilitation treatment. Conclusion Microsurgery treatment with small craniotomy lateral fissure approach for hypertensive basal ganglia intracerebral hemorrhage has the advantages of minimal invasion,complete hematoma removal and low complication and disability rates, which is worthy of promotion and application.

Background: Peste des petits ruminants (PPR), caused by the PPR virus (PPRV), is an acute and fatal contagious disease that mainly infects goats, sheep, and other artiodactyls.Peripheral blood mononuclear cells (PBMCs) are considered the primary innate immune cells. Objectives: PBMCs derived from goats were infected with PPRV and analyzed to detect the relationship between PPRV replication and apoptosis or the inflammatory response. Methods: Quantitative real-time polymerase chain reaction was used to identify PPRV replication and cytokines expression. Flow cytometry was conducted to detect apoptosis and the differentiation of CD4+ and CD8+T cells after PPRV infection. Results: PPRV stimulated the differentiation of CD4+ and CD8+ T cells. In addition, PPRV induced apoptosis in goat PBMCs. Furthermore, apoptosis and the inflammatory response induced by PPRV could be suppressed by Z-VAD-FMK and Z-YVAD-FMK, respectively.Moreover, the virus titer of PPRV was attenuated by inhibiting caspase-1-dependent apoptosis and inflammation. Conclusions This study showed that apoptosis and the inflammatory response play an essential role in PPR viral replication in vitro, providing a new mechanism related to the cell host response.
