Objective To investigate the prevalence of adult osteofluomsis in the endemic fluomsis areas in Tianjin and to provide scientific foundation for endemic fluorosis.Methods Stratified sampling in 55 villages were selected in 3 areas with slight,moderate and severe fluorosis regions in Tianjin from April to June in 2008.Water fluorine were tested and clinical osteofluorosis examinations were conducted to the population aging 16 and above in the villages.Tweenty villages were selected randomly in the slight,moderate and severe fluorosis regions.X-ray osteofluorosis examination were conducted to patients and suspected patients in these 20 villages.Results The geometric mean fluoride content in the water for the 3 areas were 1.35 mg/L,3.44 mg/L,5.49 mg/L,respectively.The prevalence of osteofluorosis were 36.7%(44/120),20.6%(33/160),39.4%(43/109),respectively.The prevalence of osteofluorosis Was increased gradually(r=0.534,P<0.01)and the symptoms and signs of the disease were more serious(H=84.813,P<0.01).The prevalence of X-ray diagnosis Was increased gradually(r=0.990,P<0.01)and signs of the disease were more severe(H=25.169,P<0.01)with an increase in age.There was no statistical significance of prevalence rate of osteofluorosis between males and females,regardless if it Was a clinical diagnosis(X2=0.343,P>0.05)or an X-ray diagnosis(X2=3.532,P>0.05).Conclusions Adult osteofluorosis to a certain extent is still prevalent in the fluorosis areas in Tianjin.Endemic fluorosis is still rampant.Improving water in fulorosis areas should be mandatory.

OBJECTIVETo compare the therapeutic effects of high-frequency oscillatory ventilation+pulmonary surfactant (HFOV+PS), conventional mechanical ventilation+pulmonary surfactant (CMV+PS), and conventional mechanical ventilation (CMV) alone for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in neonates.

METHODSA total of 136 neonates with ALI/ARDS were enrolled, among whom 73 had ALI and 63 had ARDS. They were divided into HFOV+PS group (n=45), CMV+PS group (n=53), and CMV group (n=38). The neonates in the first two groups were given PS at a dose of 70-100 mg/kg. The partial pressure of oxygen (PaO), partial pressure of carbon dioxide (PaCO), PaO/fraction of inspired oxygen (FiO), oxygenation index (OI), and respiratory index (RI) were measured at 0, 12, 24, 48, and 72 hours of mechanical ventilation.

RESULTSAt 12, 24, and 48 hours of mechanical ventilation, the HFOV+PS group had higher PaOand lower PaCOthan the CMV+PS and CMV groups (P<0.05). At 12, 24, 48, and 72 hours of mechanical ventilation, the HFOV+PS group had higher PaO/FiOand lower OI and RI than the CMV+PS and CMV groups (P<0.05). The HFOV+PS group had shorter durations of mechanical ventilation and oxygen use than the CMV+PS and CMV groups (P<0.05). There were no significant differences in the incidence rates of air leakage and intracranial hemorrhage and cure rate between the three groups.

CONCLUSIONSIn neonates with ALI/ARDS, HFOV combined with PS can improve pulmonary function more effectively and shorten the durations of mechanical ventilation and oxygen use compared with CMV+PS and CMV alone. It does not increase the incidence of complications.

OBJECTIVETo investigate the significance of serum IgD quantitation in evaluation of clinical efficacy in IgD myeloma.

METHODSSerum IgD and free light chain (sFLC) levels were determined by immune scatter turbidimetry with SPA plus analysis machine in 29 patients with IgD multiple myeloma (MM) achieving VGPR or better response following previous treatments. The concurrent immunofixation electrophoresis (IFE) results were also incorporated and analyzed.

RESULTSIncreased IgD levels were detected in 1 of 12 patients achieving sCR, 2 of 5 patients achieving CR and 4 of 12 patients achieving VGPR, respectively. The median progression-free survival (PFS) was 38.5 months, 34.1 months and 15.5 months for patients achieving sCR, CR and VGPR, respectively, with a significant difference between sCR and VGPR groups (P=0.022), and between CR and VGPR groups (P=0.018). There was no difference in overall survival (OS) among sCR, CR and VGPR groups (P>0.05). The median PFS were 7.8, 33.7 and 43.9 months, respectively for the patients with both abnormal sFLC ratios and IgD levels (6 cases, Group A), with either abnormal sFLC ratios or increased IgD levels (10 cases, Group B) or with normal sFLC ratios and IgD levels (13 cases, Group C). A significant PFS benefit of Group A over Group C was found (P=0.033), and no differences in terms of OS among three groups (P>0.05).

CONCLUSIONIgD levels may remain abnormal in IgD MM patients who have achieved VGPR or better response, and IgD quantitation represented a useful assay complementary to the current lab examinations. IgD quantitation assay was of significance in clinical efficacy evaluation and survival judgement, and should be incorporated into the evaluation parameters used for IgD MM in addition to sFLC and IFE assays.

OBJECTIVETo explore the toxic effect of fluoride on the human thyroid cells (Nthy-ori 3-1) and its mechanism.

METHODSNthy-ori 3-1 cells were exposed to 0.0, 0.1, 1.0, 3.0 mmol/L of sodium fluoride (NaF) in vitro. After 24 hours incubation, 3 (4,5-Dimethylthiazol-z-yl)-3, 5-diphenyltetrazolium bromide (MTT) assay and lactate dehydrogenase (LDH) assay were used to measure cell viability and the LDH leakage rate. Reactive oxygen species (ROS) level, constituent ratio of the cell cycle, and apoptosis rate were measured by flow cytometry.

RESULTSComparing to viability of control group (set as 100.00%), the cell viability of the 1.0, 3.0 mmol/L fluoride-treated groups (76.64 +/- 9.13)%, (64.04 +/- 6.32)% were significantly decreased (all P values <0.01). LDH leakage rate and ROS level of the 3.0 mmol/L fluoride-treated group ((48.66 +/-7.15)%, (29993.50 +/- 1786. 86) FI) were significantly increased (all P values <0.01) compared to control group ((35.24 +/- 3.02)%, (13021.33 +/- 1067.55) FI). The G0/G1 phase cells of the 1.0 mmol/L fluoride-treated group ((40.76 +/- 5.65)%) were lower than control group (60.09 +/- 1.76)% (P < 0.01), yet the percentage of cells in S phase ((54.05 +/- 4.59)%) were higher than the control group (32.59 +/- 2.43) % (P < 0.01). Comparing to control group ((9.64 +/- 3.44)%), the percentage of apoptosis cells increased in the 3.0 mmol/L fluoride-treated group ((20.09 +/- 3.22)%) (P < 0.01).

CONCLUSIONTo Nthy-ori 3-1 cells, fluoride under experimental concentrations decreases cell viability, improve the LDH leakage rate, and ROS level. It blocks the cells in S phase and induce cell apoptosis.

OBJECTIVETo study the expression of signal transducer and activator of transcription 3 (Stat3), hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) in Wilms' tumor and their roles in the development of Wilms' tumor.

METHODSThe expression of Stat3, HIF-1alpha and VEGF were detected by the immunohistochemical staining in 52 specimens from Wilms' tumor tissues, 47 from adjacent kidney tissues and 8 from normal kidney tissues. The expression intensity was analyzed by computer image processing.

RESULTSThe expression of Stat3, HIF-1 and VEGF were significantly up-regulated in Wilms' tumor tissues compared to those in adjacent tissues and normal kidney tissues (P < 0.05). Stat3 and VEGF proteins in Wilms' tumor tissues of stage III-IV and high risk histopathology were significantly higher than those of stage I-II and low risk histopathology. The higher expression of HIF-1 in Wilms' tumor tissues was shown in tumors with high risk histopathology and tumor size > or = 6 cm.

CONCLUSIONSIncreased expression of Stat3, HIF-1 and VEGF were found in Wilms' tumor tissues, and may be related to the development and angiogenesis of Wilms' tumor. Stat3 may regulate the expression of HIF-1 and VEGF, so it could be an effective target for inhibiting VEGF expression and angiogenesis of Wilms' tumor.
