Clinical records of a patient with olfactory neuroblastoma presented with hyponatremia as initial symptoms were analyzed and the literatures were reviewed. At initial onset, the patient presented with hyponatremia. After pathological examination, the diagnosis was olfactory neuroblastoma. The blood sodium has been normal after operation and radiotherapy. The incidence rate of olfactory neuroblastoma is low, and it is easily misdiagnosed. Its diagnosis relies on pathological examination. We should pay more attention to the unspecific symptoms of patients with hyponatremia, which can help to improve early diagnosis and the prognosis.

Objective:To evaluate the antimicrobial effect of ozonated water on the putative periodontopathic bacteria.Methods:Pophyromonas gingivalis (P.g)ATCC33277,Haemophilus actinomycetemcomitans (H.a)ATCC29522,Fusobacterium nucleatum (F.n)ATCC1 0957 and clinically seperated strain of P.g(C -P.g)were treated by ozonated water with ozone concentration(mg/L) of 0.03,0.06 and 0.1 2 for 30,60,90 and 1 20 s respectively.The bactericidal effect was tested by bactericidal assay.H2 O2 was used as the positive control and distilled water as the negative control.Results:The antimicrobial rate of ozonated water agaist the bacteria increased with the ozone concentration increase.There was no statistic diffrence of the effect on P.g and C -P.g(P >0.05).Linear regression analysis showed that the βvalues of the concentration factor were over 0.95,that of the time factor under 0.1 1 .Conclu-sion:The ozonated water has dose-dependent bactericidal effect on P.g,H.a and F.n.

BACKGROUND: Recent studies have suggested that conversion from cyclosporine A (CsA) to tacrolimus (FK 506)-based regimen can improve renal allograft function and survival rate. But little is known about whether the conversion from CsA to tacrolimus(FK 506) plus mycophenolate mofetil (MMF)-based regimen exhibits the same or similar clinical efficacy. OBJECTIVE: To investigate the clinical efficacy and safety of converting CsA to FK506 plus MMF in treatment of different types of chronic allograft nephropathy (CAN). DESIGN, TIME AND SETTING: An observational and controlled trial was performed at the Center for Organ Transplantation, Zhujiang Hospital, Southern Medical University from January 2005 to October 2007. PARTICIPANTS: Fifteen-nine enrolled patients received CsA-based regimen after renal allografting. Following pathological confirm and typing, all patients were assigned to two groups: CAN with chronic rejection (CR, n = 31) and CAN without chronic rejection (non-CR, n = 28). FK 56 was purchased from Fujisawa Pharmaceutical Company, Ltd., Japan. MMF was sourced from Shanghai Roche Pharmaceutical Co., Ltd., China. METHODS: When patients were diagnosed CAN, the CsA regimen was conversed to FK506 plus MMF regimen. FK506 initiated at a dose of 0.08 mg/kg per day and then was adjusted to achieve steady-state whole blood trough levels of approximately 5-8 μg/L. MMF was used at a fixed dosage, 1.0 g/d, twice a day, only if relative adverse events occurred. All patients were followed up at least 6 months. MAIN OUTCOME MEASURES: Serum creatinine(Scr), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), 24-h proteinuria, glomerular filtration rate (GFR), and complications. RESULTS: All initial 59 patients were included in the final analysis. At 6 months after regimen conversion, the levels of Scr, TC, TG, LDL, and 24-hour proteinuria were significantly reduced in non-CR, in particular CR, groups, compared with prior to conversion (P< 0.05). GFR was markedly increased in both the CR and non-CR groups (P< 0.05). In the CR group, 20 patients obtained improved results, 7 got stable results, and 4 showed ineffective results. The effective rate of regimen conversion was 64.5% and 32.1% in the CR and non-CR groups, respectively, and significant difference existed between the two groups (P < 0.05). Compared with prior to conversion, the incidence of hypertension and hyperlipemia was significantly decreased after regimen conversion (P< 0.05). There was no significant difference in diabetes mellitus, opportunistic infection, and malignancy between prior to and after regimen conversion. CONCLUSION: FK506 plus MMF-based regimen can markedly improve the function of renal graft of CAN, in particular CR, patients.

To explore the clinical significance of changes in maximal expiratory flow in 50% and 25% vital capacity (Vmax50% & Vmax25%) before and after bronchodilator reversibility testing in patients with asthma.Forced expiratory volume in one second (FEV1),Vmax50% and Vmax25% were measured before and after bronchodilator reversibility testing in 118 patients with asthma and 82 with chronic obstructive pulmonary disease (COPD).The rate of positive reversibility in Vmax50% was significantly higher than that in FEV1 in 118 asthmatics (x2 =7.995,P =0.007).The rates of positive reversibility in Vmax50% and Vmax25% were significantly higher in asthmatics than those in COPD patients (x2 =9.335,P =0.009).
