ABSTRACT

OBJECTIVE@#To study the application of surgical locating guides based on cone beam computed tomography (CBCT) and computer-aided design/computer-aided manufacturing (CAD/CAM) technique on extraction of impacted supernumerary teeth.@*METHODS@#This study included 15 patients with impacted supernumerary teeth in anterior maxillary. Surgical approach was determined by CBCT. Surgical locating guides of labial approach or palatal approach were designed and fabricated by CAD/CAM technique. Impacted supernumerary teeth were extracted under the location of surgical locating guides.@*RESULTS@#Surgical locating guides were well attached in the operation. The impacted supernumerary teeth were located and exposed rapidly, and the adjacent important anatomical structures were avoided.@*CONCLUSIONS@#Surgical locating guides benefit the accurate detection and reduction of trauma in extraction of impacted supernumerary teeth.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of right heart catheterization through the antebrachium veins.</p><p><b>METHODS</b>A total of 68 consecutive patients suspected with pulmonary vascular diseases underwent standard right heart catheterization and pulmonary angiography through the antebrachium veins were enrolled in this multicenter, cross-sectional study.</p><p><b>RESULTS</b>The rate of successfully inserting the sheath into antebrachium veins was as high as 97.1% (66/68) and the rate of successfully performing right heart catheterization or pulmonary angiography through vascular access of antebrachium veins was 91.2% (62/68). The reasons of unsuccessful inserting the catheter to the right heart were due to the abnormality of antebrachium veins (2 cases) or stenosis of subclavian vein (3 cases) or unsatisfactory engorging of antebrachium veins since the history of drug injection (1 case). Haemorrhage of branch of axillary vein was the only adverse event occurred in one patient.</p><p><b>CONCLUSION</b>It is a safe, convenient and well-tolerant option to perform right heart catheterization and pulmonary angiography through the vascular access of antebrachium veins.</p>

ABSTRACT

In this study,nearly 200 endophytic bacteria were isolated from different part of Huperzia serrata, over 60 bacterium with clear antifungal activity were selected from those cultures.Among them,strain H-6 exhibited the highest antifungal activity which was strongly inhibits the growth of many plant pathogenic fungi such as Sclerotinia scleroliorum,Fusarium graminearumt,Sclerotinia libertiana,Phytophthora capsici Leonia and Sesame fusarium wilt.According to the characteristics of morphology,physiology and biochem- istry tests and the comparison of 16S rDNA sequence,the strain H-6 was similar to the Burkholderia.So strain H-6 was identified as Burkholderia sp.H-6.The results also showed that Burkholderia sp.H-6 was markedly different from Burkholderia cepacia that was applied widely in agriculture as antagonistic bacteria. The medium and culture conditions of the strain all were optimized by single factor and orthogonal experiments.In the investigation of the culture condition,growth was carried out in a basal medium(potato juice)and gradually supplemented with the various ingredients to be investigated.The major ingredients be- ing investigated included carbon sources and nitrogen sources.The optimal antifungal activity production condition is growth in a medium(potato juice with 2.5%mannitol and 0.1%NaNO3),initial pH 4.0 at 28℃.
