Objective We aimed to use 1H-MRS to characterize metabolite concentrations in the bilateral hippo?campus in GPI patient. Methods Metabolite ratios in the bilateral hippocampus were compared between patients with GPI (n=52) and Normal Control (NC) (n=38). Clinical neurological tests were measured in all subjects and were correlat?ed to the metabolite concentrations. Results The GPI patients showed significantly lower concentrations of N-acetylas?partate(NAA)/creatine(Cr) ratios in the bilateral hippocampus region compared to the NC subjects. There was significant?ly difference in the NAA/Cr ratios between the mild GPI dementia and the severe GPI dementia groups on the left hippo?campus region. We found that the NAA/Cr ratios concentrations were positively correlated with Mini Mental state Exami?nation (MMSE) and Montreal Cognitive Assessment scale (MoCA) scores in the left hippocampus region and the mI/Cr ra?tios concentrations were positively correlated. Conclusions GPI Patients have neuronal dysfunction in the bilateral hippo?campus. The severity of cognitive impairments is associated with the severity of the damage in the left side.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

Objective To investigate the pathologic features, diagnosis and differential diagnosis of inflammatory myofibroblastic tumor (IMT) in urinary bladder. Methods It was retrospectively reviewed for the characters of pathologic features and immunohistochemistry type in 3 patients diagnosed IMT in urinary bladder. Results 3 patients including 1 female and 2 male were 15, 36 and 60 years old (mean age 37),respectively. All patients underwent partial cystectomy. All cases presented single or multiple, polypoid or nodular mass(es), ranging in size from 1.8 to 5.5 cm. Microscopically, the tumor cell grew in invasive pattern, and were spindled with prominent nucleoli. The lesions varied from highly myxoid to highly cellular lesions. The mitotic rates were invisible. AE1/AE3, CK18 and ALK were positive in IMT. Follow-up was available for 3 patients (2, 18 and 18 months, respectively). None developed recurrences or metastasis. Conclusion IMT in urinary bladder are rare tumors. IMT grows in invasive pattern, and are spindled with prominent nucleoli.The main differential diagnosis of IMT includes embryonal rhabdomyosarcoma in juvenile, sarcomatoid urothelial carcinoma and leiomyosarcoma in adult.
