ABSTRACT
<p><b>OBJECTIVE</b>To assess the application of ultrathin transnasal gastroscopy in transnasal percutaneous endoscopic gastrostomy (nPEG) in patients with trimus and/or pharyngeal narrowing.</p><p><b>METHODS</b>Nine consecutive patients underwent PEG with the Introducer method using conventional gastroscopy (5 cases) or ultrathin transnasal gastroscopy (4 cases). Among the 4 patients undergoing nPEG, 3 received radiotherapy for nasopharyngeal cancer, including two with trimus and one with trimus and pharyngeal narrowing. The procedure time, safety, discomfort and complications in these cases were compared and evaluated.</p><p><b>RESULTS</b>The average procedure time of PEG was 17+/-3.5 min in conventional gastroscopy group and 17+/-3.1 min in nPEG group. No complications were observed in these patients, but the patients in nPEG group reported less discomfort associated with the procedure.</p><p><b>CONCLUSIONS</b>Ultrathin transnasal gastroscopy reduces the discomfort of the procedure and is safer than conventional gastroscopy for PEG, especially in patients with trimus and/or pharyngeal narrowing.</p>

<p><b>OBJECTIVE</b>To observe the effect of herbal eye drop Reduqing (clearing toxic heat) on herpes simplex virus (HSV) on the cytopathic effect in cell culture in vitro.</p><p><b>METHODS</b>The maximal non-toxic Reduqing eye drop concentration added to cell culture infected with 100 and 10TCID50 of herpes simplex virus? (HSV-1) to observe the inhibitory effect of the medicine on HSV-I induced cytopathic effect.</p><p><b>RESULTS</b>The Reduqing eye drop at maximal non-toxic concentration could obviously inhibit the cytopatic effect induced by 100TCID50 and 10TCID50 HSV-I. No statistically significant difference was found when compared with 0.1% acyclovir eye drop (P>0.05), on cytopathic effect occurred with boty eye drops. However, there was significant difference when compared with control group(P<0.05). The inhibitory effect of concentrations of Reduqing at 500,000 and 63,000 microg/L was stronger than that of 2,000,000 and 1,000,000 microg/L (P 0.01). The maximal tolerable concentration of Reduqing eye drop by the cell was 2,000,000 microg/L (1:80 dilution), which was higher than that of 5,000 microg/L(1:400 dilution) acyclovir eye drop.</p><p><b>CONCLUSIONS</b>These results suggest that Reduqing eye drop could markedly inhibit the cytopathic effects caused by HSV-I. The Reduqing eye drop showed remarkably low toxic effect to the cells as compared to acyclovir eye drop.</p>
