OBJECTIVETo compare the changes of enamel surface and cross-sectional microhardness of artificial caries immediately and after the twice demineralization through coating resin infiltration, fluoride varnish and fissure sealant.

METHODSA total of forty bovine lower incisors enamel samples with artificial caries lesions by the demineralization liquid were used in the experiment. The specimens were then randomly divided into four groups as group A(resin infiltration), B(fluoride varnish), C (fissure sealant), D(control), 10 specimens in each group. The samples were sectioned vertically into two halves through the centre. One half of each sample the surface and cross-sectional microhardness was measured. The other half was put into demineralization liquid for 14 days, then the surface and cross-sectional microhardness was measured again. The cross section morphology of the samples was observed by scanning electron microscope.

RESULTSThe surface of enamel had the highest microhardness value, and with the increase of cross- sectional depth, the microhardness value declined gradually. Variance analysis showed that the difference was statistically significant in the cross-section of different depth among the four groups(P<0.05). The microhardness values of the surface and the cross- section at 40 µm of each group in immediate measure showed the values were significantly higher in group A, B and C than in group D. There was no significant difference in the microhardness value of cross-section at 80 µm between group A[(324 ± 17) kg/mm(2)] and group C[(316 ± 20) kg/mm(2)], but they were significantly higher than group D. There was no significant difference between group B[(303 ± 13) kg/mm(2)] and group D[(294 ± 23) kg/mm(2)]. At 120 µm level, the microhardness value of group A was significantly higher than those of the other three groups. After the twice demineralization, the enamel surface microhardness value of the specimens was the same as the first measurement. In the cross-section at 40 µm level, the microhardness value was equal to the value of cross-section at 80 µm level of the first measurement. In the cross- section at 80 µm and 120 µm level, the microhardness value of group A was significantly higher than those of the other three groups.

CONCLUSIONSResin infiltration can effectively strengthen microhardness of enamel surface and cross-section of different depth of artificial caries.

Objective To investigate the clinical pathological characteristics, diagnosis and treatment of breast rhabdomyosarcoma, and to enhance the awareness of malignancy infiltration to bone marrow (BM). Methods The data of one case of Rhabdomyosarcoma of breast were analyzed retrospectively. BM aspirate and biopsy, morphology, immunology, cytogenetics, molecular biology (MICM) in different parts of BM, peripheral blood smear, fine puncture of breast mass, final biopsy of breast mass by Mammotome System and whole body PET-CT were performed. The immunochemistry stain of specimen of breast mass was used. Results The peripheral blood smear of this patient showed immature erythrocytes, leucocytes and classification of unknown cells which were consistent with BM morphology. The results of BM aspirate and biopsy depicted a hypercellular specimen with disseminated unknown cells infiltration. Unknown cells were positive for CD56 and negative for any hematopoietic markers by flow cytometry. The whole body PET-CT showed that uptake of 18F-FDG of bilateral breast and whole BM was increased, whereas the mass of breast was not presented by CT. PET-CT suggested a probable malignant hematologic disease. The enough specimen of breast mass got from Mammotome System showed embryonal rhabdomyosarcoma, and the tumor cells were positive for MyoD1, Vimentin and Desmin. Conclusions It is a challenge for early diagnosis of solid sarcoma with unknown origin which diffusely infiltrating into BM. Negative expression of hematopoietic markers by flow cytometry plays a role on differential diagnosis in this setting, whereas PET-CT only provides a valuable reference. Enough specimen and immunohistochemical staining could provide solid evidences of diagnosis.

Objective To explore the clinical features and causes of misdiagnosis of the patients with acquired deficiency of vitamin K-dependent coagulation factors (ADVKDCF). Methods Retrospective analysis was performed with the data from 62 patients with ADVKDCF for etiological factors, clinical manifestations,laboratory examinations, diagnosis and treatments. Results Among the 62 patients, 51 patients were with unknown causes( subgroup A) and 11 were with clear histories of anticoagulant rodenticide poisoning( subgroup B). The presentations of hemorrhage of the patients varied with hematuria as the most common first symptom,followed by skin, mucosa, muscle, internal organs bleeding (28/62). The most common hemorrhage symptom is hematuria. 35 of the 62 patients had hemoglobin(Hb) levels less than 100 g/L due to blood loss( the lowest level was 32 g/L). Thirty-eight patients were misdiagnosed at the first visit and the median time from hemorrhage manifestation to definite diagnosis was 8 days (range,2 to 192 days). ADVKDCF was mostly misdiagnosed as the urinary system diseases (23/38), followed by hemophilia (8/38). Laboratory examinations showed normal platelet count , throm bin time (TT) and normal fibrinogen(Fg) concentration, but prolonged plasma prothrombin time (PT), activated partial prothrombin time (APTT) and international normalized ration (INR). All of patients received high dose vitamin K ( intravenous vitamin K1 with a initial dose of 20 to 240 mg/d and then oral vitamin K4 maintenance) . The bleeding symptoms disappeared 1 day after treatment and the Hb levels increased dramatically. There were significant differences in PT, APTT and INR of the patients before and after treatment( P ＜0. 01 ). Followed by a median follow - up of 8 months , no patient had severe adverse effects or recurrence. Conclusion The hemorrhage presentations of the patients with ADVKDCF are various. The most common hemorrhage symptom is hematuria. The misdiagnosis rate of ADVKDCF is high with urinary systems disorders as the most common misdiagnosis. Sequential treatment with vitamin K is an effective and safe method to prevent recurrence. Early detection of coagulation function is helpful to reduce misdiagnosis possibility.
