ABSTRACT

Objective The etiology and pathogenesis of recurrent aphtha ulcer (RAU) are not yet sufficiently clear and there has been no cure for it hitherto. This study aimed to compare the short-term effect of Kangfuxin Liquid (KFX) versus that of Beifuji Solution (BFJ, a topical solution of the recombinant bovine alkaline fibroblast growth factor) on refractory minor RAU (RMiRAU).Methods This prospective study included 150 cases of RMiRAU treated in Nanjing Hospital of Stomatology between March 2016 and June 2018. The patients were randomized into five groups of equal number: KFX, BFJ, oral control (oral isotonic saline), topical control (topical isotonic saline), and blank control (not treated). We measured the ulcer area and obtained the pain index at 1, 3, 5 and 7 days of treatment. We also recorded the onset time and duration of analgesia as well as the course of ulcer after initial medication.Results At 3, 5, and 7 days after treatment, the ulcer areas in the KFX group, significantly smaller than in the oral control and blank control groups, and also smaller in the BFJ than in the topical control and blank control groups (P<0.05). At 3 and 5 days, the pain indexes were (3.35±1.23) and (2.32±1.80) in the BFJ group, significantly lower than (5.08±1.83) and (3.53±1.50) in the topical control and (5.50±1.69) and (3.79±1.34) in the blank control group (P<0.05), and lower in the KFX than in the oral control ([5.29±1.73] and [3.74±1.42]) and blank control groups (P<0.05);On day 3, the pain index of the BFJ group is much smaller than the KFX liquid group (P<0.05). The course of ulcer after initial medication was remarkably shorter, the onset of analgesia significantly later, and duration of analgesia markedly shorter in the KFX than in the BFJ group (all P<0.05).Conclusion Both KFX and BFJ have a good short clinical effect on RAU. KFX has advantage in decreasingulcer duration; BFJ has fast onset time and long maintenance time.

ABSTRACT

Laugier-Hunziker syndrome (LHS) is an acquired pigmentary condition affecting lips, oral mucosa and acral area, frequently associated with longitudinal melanonychia. There is neither malignant predisposition nor underlying systemic abnormality associated with LHS. Herein, we present three uncommon cases of LHS with possibly new feature of nail pigmentation, which were diagnosed during the past 2 years. We also review the clinical and histological findings, differential diagnosis, and treatment of the syndrome in published literature.

ABSTRACT

<p><b>AIM</b>To study the relationship between resonance Rayleigh scattering(RRS) and the formation of association nanoparticle, and to develop a new and sensitive RRS method for the determination of trace berberine (BB).</p><p><b>METHODS</b>The association nanoparticle between BB and tetraphenylboron (TPB) was investigated by means of RRS, absorption spectral method and transmission electron microscope (TEM).</p><p><b>RESULTS</b>In pH 5.0 NaAc-HAc buffer solution, BB and TPB combine to BB-TPB association complex. The association complexes aggregate to (BB-TPB)n association nanoparticles, due to the strong hydrophobic force and Van der Waals force. It exhibits a resonance Rayleigh scattering peak at 470 nm, a maximum absorption peak at 368 nm. A new RRS method was proposed for the determination of 0.06 to 5.28 mg.L-1 BB in real samples with satisfactory results. The detection limit is 26 micrograms.L-1.</p><p><b>CONCLUSION</b>The TEM of (BBjAgp-TPBj + p)h composite association nanoparticles was observed by means of composite association nanoreaction both TPB- and BB+ or Ag+. The results indicated that the formation of (BB-TPB)n association nanoparticles and interface of solid-liquid results in the enhanced resonance light-scattering. This new RRS method showed high sensitivity, and had been successfully applied to the determination of BB in real samples.</p>
