Since laser therapy has been applied to dentistry, many dental practitioners are very interested in laser therapy on various intraoral soft tissue lesions including gingival hyperplasia and aphthous ulcer. The purpose of the present study was to determine the therapeutic effect and the harmful effect of a pulsed-Nd:YAG laser irradiation on human gingival tissue. In twenty periodontal patients with gingival enlargement, the facial gingival surface of maxillary anterior teeth was randomly irradiated at various power of 1.0W(100mJ, 10Hz), 3.0W(100mJ, 30Hz) and 6.0W(150mJ, 40Hz) for 60 seconds by contact delivery of a pulsed-Nd:Y AG laser(EN.EL.EN060, Italy). Immediately after laser irradiation, the gingival tissues were surgically excised and prepared in size of 1mm3. Subsequently the specimens were processed for prefixation and postfixation, embedded with epon mixture, sectioned in 1micron thickness, stained with uranyl acetate and lead citrate, and observed under transmission electron microscope(JEM 100 CXII). Following findings were observed; 1. In the gingival specimens irradiated with 1.0W power, widening of intercelluar space and minute vesicle formation along the widened intercellular space were noted at the epithelial cells adjacent to irradiated area. 2. In the gingival specimens irradiated with 3.0W power, the disruption of cellular membrane, aggregation of cytoplasm, and loss of intercellular space were observed at the epithelial cells adjacent to irradiated area. 3. In the gingival specimens irradiated with 6.0W power, the disruption of nuclear and cellular membrane was observed at the epithelial cells adjacent to irradiated area. The ultrastructural findings of this study suggest that surgical application of a pulsed-Nd:YAG laser on human gingival tissue may lead somewhat delayed wound healing due to damage of epithelial cells adjacent to irradiated area.

OBJECTIVE: To study the clinical features of children with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome, a polygenic and multifactorial autoinflammatory disease with unknown pathogenesis. METHODS: A retrospective analysis was performed on the medical data of 13 children with PFAPA syndrome. RESULTS: All 13 children had disease onset within the age of 3 years, with a mean age of onset of (14±10) months. They all had periodic fever, with 8-18 attacks each year. The mean interictal period of fever was (30±5) days. Pharyngitis, cervical adenitis, and aphthous stomatitis were the three cardinal symptoms, with incidence rates of 100% (13/13), 85% (11/13), and 38% (5/13) respectively. There were increases in white blood cells, C-reactive protein, and erythrocyte sedimentation rate during fever. Of all the 13 children, 6 underwent whole exome sequencing and 7 underwent panel gene detection for autoinflammatory disease, and the results showed single heterozygous mutations in the CONCLUSIONS For children with unexplained periodic fever with early onset accompanied by pharyngitis, cervical adenitis, aphthous stomatitis, elevated inflammatory indices, and good response to glucocorticoids, PFAPA syndrome should be considered. This disorder has good prognosis, and early diagnosis can avoid the long-term repeated use of antibiotics.

Behcet's disease is an inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. A few cases of hematologic disease in patients with Behcet's disease have been reported in the literature. However, acute precursor T cell lymphoblastic leukemia has never been described in association with Behcet's disease. We recently encountered a case of acute precursor T cell lymphoblastic leukemia in a 62-year-old man with a prior diagnosis of Behcet's disease. The patient presented with febrile neutropenia and his bone marrow biopsy revealed acute precursor T cell lymphoblastic leukemia. He was scheduled to undergo therapeutic chemotherapy, but unfortunately he died from pneumonia prior to treatment.

OBJECTIVETo investigate the effect of Shuizhongcao Granule (SZCG) on cellular immune function in animal model of recurrent aphthous stomatitis (RAS).

METHODSExperimental animal model of RAS were established by immunological method. The modeled animals were randomized into 4 groups, Group A was the model control group, Group B was treated by Levamisole (2.5 mg/mL), Group C and D was treated with high-dose (0.5 g/mL) and low-dose (0.24 g/mL) SZCG respectively. The medication was administered via gastric perfusion, starting from the 7th week of the experiment, and continued for 28 days. Meanwhile, a normal control group was set up. Percentage of T-lymphocyte subsets, CD3, CD4 and CD8, and serum levels of interleukin 10 and 12 (IL-10 and IL-12) in peripheral blood were detected before and after treatment.

RESULTSPercentages of CD3, CD4 and CD4/CD8 ratio in the model control group were 40.50 +/- 7.46%, 30.80 +/- 5.33% and 79.56 +/- 8.32 respectively, all lower than those in the normal control group (P<0.05); level of serum IL-10 was higher (8.02 +/- 0.53 ng/L) and that of IL-12 was lower (15.51 +/- 1.35 ng/L) in the model animal than those in normal control (P<0.05). After treatment, levels of CD3, CD4, CD4/CD8 and IL-12 in Group B were 55.30 +/- 6.33%, 43.50 +/- 5.33%, 99.29 +/- 13.84 and 17.72 +/- 1.70 ng/L, those in Group C were 61.50 +/- 4.32%, 47.20 +/- 4.37%, 103.30 +/- 7.42 and 18.18 +/- 1.54 ng/L, and in Group D were 58.50 +/- 6.03%, 42.80 +/- 3.17%, 110.27 +/- 12.85 and 17.74 +/- 1.96 ng/L, respectively, all were higher than those in Group A, but levels of IL-10 in the three treatment groups were lower than that in Goup A (P<0.05 or P<0.01).

CONCLUSIONThe immune function of RAS model animals is in the suppressed condition; SZCG can improve the immune suppression to achieve its therapeutic effect on the disease.
