ABSTRACT

Objective To study the antimicrobial activity of chemically synthesized Musca domes-tica cecropin-4 (mdCec4) against Acinetobacter baumannii. Methods Minimum inhibitory concentration (MIC) and minimum bactericidal concentration(MBC) of mdCec4 against Acinetobacter baumannii were de-tected by microdilution method. Dynamic time-kill curve was monitored by microplate reader. Effects of dif-ferent influencing factors,such as NaCl,trypsin and pH value,on the antimicrobial activity of mdCec4 were assessed. The ultrastructure of Acinetobacter baumannii exposed to the MIC of mdCec4 was observed under scanning electron microscope (SEM). Results The MIC and MBC of mdCec4 against Acinetobacter bau-mannii were 4 μg/ml and 8 μg/ml,respectively. The dynamic time-kill curve revealed that mdCec4 had a high antimicrobial activity within 24 hours. The antimicrobial activity of mdCec4 was not affected by NaCl concentration ranged from 0 to 200 mmol/L, but could be inhibited by trypsin at a concentration of 1.0 mg/ml. Among Tris-HCl buffers with different pH values (6.5, 7.5, 8.8), the optimum condition for mdCec4 was pH8.8. Results of SEM showed that the degree of bacterial cell injury was positively correlated with exposing time. Conclusion This study shows that the newly discovered mdCec4 has a better antimicro-bial activity against Acinetobacter baumannii as it can eliminate Acinetobacter baumannii within a short period of time and its antimicrobial ability can last more than 24 hours. Moreover,mdCec4 has the characteristic of good stability in conditions of different concentrations of NaCl and Trypsin as well as various pH values. SEM observation shows that the MIC of mdCec4 can destroy the integrity of bacterial membrane resulting in a re-lease of a large number of cell contents, which finally lead to the death of Acinetobacter baumannii. This study provides references for further study of the antimicrobial mechanism of mdCec4 against Acinetobacter baumannii.

ABSTRACT

ABSTRACT Housefly, Musca domestica, has a complicated immune system. However, its underlying operating mechanism remains elusive. Candida albicans is a major pathogen affecting humans by causing deep infection fungous disease, but it is non-symbiotic in houseflies. To investigate the C. albicans infection process in housefly, the changes in morphological and histological and expression patterns of antimicrobial peptide were monitored to indicate the insect's response to fungal infection. The results showed that scattered brown spots were comprising melanized encapsulation and encapsulated fungal cells were initially observed at the inner side of larvae's body wall 3 h post-infection (PI). Between 6 and 36 h PI, the whole body of larvae was densely covered with the brown spots, which then gradually disappeared. The majority had disappeared at 48 h PI. Some fungi colonized in the gaps between the body wall and the muscle layer, as well as among muscle fibers of the muscle layer at 12 h PI and hyphal was observed at 18 h PI. These fungi colonized distribution changed from a continuous line to scattered spots at 24 h PI and virtually disappeared at 48 h. The results of quantitative PCR analysis revealed that in coordination with the variation during the infection, the expression levels of four antimicrobial peptides were up-regulated. In conclusion, C. albicans infection in M. domestica larvae involved the following stages: injection, infection, immune response and elimination of the pathogen. The rapid response of antimicrobial peptides, melanized encapsulation and agglutination played a vital role against the pathogenic invasion.

ABSTRACT

Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.

ABSTRACT

In order to construct and express human cardiac troponin C-linker-troponin I(P) [ cTnC-linker-TnI(P)] fusion protein, detect its activity and prepare lyophilized protein, we searched the CDs of human cTnC and cTnI from GenBank, synthesized cTnC and cTnI(30-110aa) into cloning vector by a short DNA sequence coding for 15 neutral amino acid residues. pCold I-cTnC-linker-TnI(P) was constructed and transformed into E. coli BL21(DE3). Then, cTnC-linker-TnI(P) fusion protein was induced by isopropyl-β-D-thiogalactopyranoside (IPTG). Soluable expression of cTnC-linker-TnI(P) in prokaryotic system was successfully obtained. The fusion protein was purified by Ni²⁺ Sepharose 6 Fast Flow affinity chromatography with over 95% purity and prepared into lyophilized protein. The activity of purified cTnC-linker-TnI(P) and its lyophilized protein were detected by Wondfo Finecare™ cTnI Test. Lyophilized protein of cTnC-linker-TnI(P) was stable for 10 or more days at 37 °C and 4 or more months at 25 °C and 4 °C. The expression system established in this research is feasible and efficient. Lyophilized protein is stable enough to be provided as biological raw materials for further research.

ABSTRACT

Objective To gain experimental data about breeding Musca domestica larvae by pig manure and to evaluate the effects and cost-benefit of feeding hens with larvae instead of fish powder. Methods The concentration of fatty acids and trace elements in the larvae bred with man-made fodder or pig manure were measured. The quality of eggs produced by hens fed with the larva powder or fresh larvae was investigated. Results The contents of trace elements (Ca,Fe,Cu,Zn,Se) of the larvae bred with pig manure were higher than those with man-made fodder(P0.05).
