Objective To investigate the effect of excessive fluoride,aluminum on Zn,Fe,Ca,Mg,Cuin rat blood.Methods Forty eight SD rats were randomly divided into 4 groups matched with their weights:control group,high aluminum group,high fluorine group and high fluorine-aluminum group.Aluminum content in their drinking water was 0,90,0,90 mg/L respectively.Fluorine content of their feed was 5.2,5.2,106.0,106.0 mg/kg and aluminum Was 6.8,6.8,19.7,19.7 mg/kg respectively.90 days later,the level of blood Zn,Fe,Ca,Mg, Cu Was detected by the atomic absorption spectrometry.Results Compared among these groups,Zn,Fe,Mg and Cu content of the whole blood had significant difierences(F=46.25,14.74,6.10,2.93,P<0.05),while Ca content of the whole blood did not significantly change(F=2.81.P>0.05).Factorial analysis showed that excessive intake of aluminum could significantly decreased Zn,Fe,Mg content of the blood(F=42.66,5.41,7.04,P<0.05)and excessive intake of fluorine could significantly decreased Zn,Fe,Mg,Cu content of the blood(F=64.50,37.90,9.75,6.74, P<0.05).The coexistence offluorine and Muminum had interaction to the level of Zn(F=31.59,P<0.05)and did not obviously interact with other elements(F=0.91,1.63,1.51.0.00,P>0.05).Compared with the control group [(131.30 ±13.86)μmol/L,(10.24 ±1.02),(1.71 ±0.19)mmol/L,(20.43 ±4.42)μmol/L],Zn content in the high aluminum group[(90.84±9.98)μmol/L]decreased significantly(P<0.05),so did Zn,Fe,Mg content in tlle high fluorine group[(85.85 ±10.92)μmol/L,(8.49 ±0.68),(1.52 ±0.13)mmol/L],the difference being statistically significant(P<0.05)0Zn,Fe,Mg,Cu content in the high fluorine-aluminum group,being(82.82 ±11.00)μmol/L, (8.16±0.45),(1.46±0.09)mmoL/L,(15.69±2.38)μmol/L,respectively,all decreased signitlcarIdy(P<0.05). Compared with the high aluminum group[(9.43±1.09)mmol/L],Fe content of the high fluorine aluminum group[(8.16±0.45)mmol/L]decreased significantly(P<0.05).Conclusions Excessive fluoride can cause blood zn, Fe,Mg,Cu decline,so can excessive aluminum.Combination of excessive fluofine and aiuminum has 8ignificant synergic effect on the level of Zn but have rio influence on Ca.

The aim of this study is to clarify whether edaravone postconditioning had protective effect against renal ischemia/reperfusion injury and to compare the protective effect between ischemic postconditioning and edaravone postconditioning. Rats were subjected to 45 min ischemia followed by 24 h reperfusion. The rats were randomly assigned to seven groups: a sham-operated control group, an ischemia/reperfusion group, an ischemic postconditioning group, a normal saline vehicle postconditioning group and an edaravone postconditioning (1, 3, and 6 mg x kg(-1)) group. Renal function was assessed by serum creatinine and BUN concentration, while histological damage of renal tissue was assessed with HE staining. MDA content and SOD activity of renal tissue were determined. TUNEL staining was performed to analyze the apoptosis of the tubular epithelial cells, the protein level of Bcl-2 and Bax in renal tissue was examined by Western blotting. Compared to the ischemia/reperfusion group, edaravone postconditioning significantly decreased serum creatinine and BUN concentration, and ameliorated histological damage of renal tissue. MDA was less after 24 h reperfusion in the edaravone postconditioning group than that in the ischemia/reperfusion group, consistent with an increase in SOD activity. In addition, edaravone postconditioning decreased TUNEL-positive cells and Bax expression, and increased Bcl-2 expression. Results detected in the edaravone postconditioning group showed no significant difference from the ischemic postconditioning group. Edaravone administered during the last 3 min of ischemia, prior to reperfusion induces a pharmacological postconditioning in vivo against renal ischemia/reperfusion injury in rats. This protection is similar to that observed with ischemic postconditioning.

OBJECTIVETo observe the improvements of synchronous treatment of bilateral scalp acupuncture and rehabilitation training on activities of daily life in patients with cerebral infarction at acute phase, so as to compare the efficacy differences between scalp acupuncture at bilateral and affected side as well as differences between synchronous and non-synchronous treatment.

METHODSNinety patients of acute-phase cerebral infarction with motor dysfunction were randomly divided into three groups. The observation group was treated with synchronous treatment of scalp acupuncture at the Dingzhongxian (middle line of vertex), bilateral Dingnieqianxiexian (anterior oblique line of vertex-temporal) and bilateral Dingniehouxiexian (posterior oblique line of vertex-temporal) and rehabilitation training; the control group A was treated with synchronous treatment of affected scalp acupuncture at the Dingzhongxian, affected Dingnieqianxiexian and affected Dingniehouxiexian and rehabilitation training; the control group B was treated with bilateral scalp acupuncture for 4 h, followed by rehabilitation training. All the patients took the treatment once a day, and 6 days for a course of treatment for total of 4 courses. The modified Barthel index (MBI), activities of daily living (ADL) and Fugl-Meyer motor assessment (FMA) were used to perform efficacy assessment before treatment, in the 14th days of treatment and in the 28th days of treatment in three groups.

RESULTSAfter treatment, three indices at each time point were superior to those before the treatment in three groups (all P<0.01) ; the improvements of ADL and FMA in the observation group after 28 days of treatment were superior to those in the control group A and control group B (all P<0.05), and the improvement of MBI was superior to that in the control group B (P<0.05).

CONCLUSIONThe synchronous treatment of bilateral scalp acupuncture and rehabilitation training could significantly improve the activities of daily life and motor function in patients with cerebral infarction at acute phase, which is superior to scalp acupuncture at affected side and non-synchronous treatment.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

Objective To investigate the state of endemic fluorosis, running status of water improvement project to reduce fluoride in Jiangsu province, and to provide a scientific basis for prevention and control of endemic fluorosis. Methods In 2008, in the ten key counties of endemic fluorosis (zone), in Xuzhou,Lianyungang and Suqian, a stratified sampling method was employed to select 40 diseased villages according to their past water fluoride survey data. All children aged 8 to 12 were examined dental fluorosis, and all adults over 16 years were examined clinical skeletal fluorosis. Thirty per cent of the 40 diseased villages were selected, and 20 adults over the age of 16 in each selected village were examined by X-ray, respectively;50% of the 40 diseased villages were selected, and 30 any time urine samples of children aged 8 to 12 in each diseased village were tested urine fluoride. In each city, select a county, the status of water improvement project to reduce fluoride, water supply capacity and coverage in the county were investigated. Results A total of 3560 children aged 8 to 12 were examined, the detection rate of dental fluorosis was 38.51% (1371/3560), tooth defect rate was 5.34% (190/3560), and dental fluorosis index was 0.8. Seven hundred and eight urine samples were tested, the median urinary fluoride was 1.47 mg/L and the range was 0.08 ~ 10.08 mg/L. Clinical detection of skeletal fluorosis was 21.3% among adults over the age of 16, and X-ray detection rate of skeletal fluorosis was 39.2% (123/314).Investigated a total of 248 facilities of centralized water improvement projects, no funds to run or damaged 49, the water fluoride > 1.0 mg/L was 18. Conclusions Endemic fluorosis in Northern Jiangsu province has not been controlled completely, but has a rising trend, we should further strengthen the supervision of water fluoride reduction.

Objective To observe the effects of soybean,selenium and spirulina on hemoglobin(Hb)of rats intoxicated with fluorine and aluminiums.Methods According to body weight,84 SD rats were randomly divided into control group,high aluminum group,high fluorine group,high fluorine-aluminum group,high fluorine-aluminium intoxicated rats strengthened with soybean group,high fluorine-aluminium intoxicated rats strengthened with selenium group and high fluorine-aluminium intoxicated rats strengthened with spirulina group,12 in each group.Rats in the control group and the high aluminum group were fed with feed containing 5.2 mg/kg of fluorine and 6.8 mg/kg of aluminum.In other groups,fluorine wag 106 mg/Kg and aluminum 19.7 mg/kg.Fluorine and aluminum concentration in the drinking water of the control group and the high fluorine group were 0.69 mg/L and 0.20 mg/L,respectively.In other groups' drinking water,these values were 0.69 mg/L and 90.2 mg/L,respectively.Ninety days later,Hb concentration of the whole blood was tested.Results Hb concentration of the control group,the high aluminum group,the high fluorine group,and the high fluorine-aluminum group were (160.8±6.3),(142.2±15.9),(156.1±4.9)and(145.2±6.2)g/L,respectively.Fluorine had an effect on the concentration of Hb(F=29.56,P<0.05).The Hb concentration of the high fluorine-aluminum group,the strengthened with soybean group,the strengthened with selenium group and the strengthened with Spirulina group were(145.2±6.2),(150.7±17.7),(156.8±14.5),(154.5±17.8)g/L,respectively.Though the concentration of Hb had increased,there was no significant difference between the four groups(χ2=3.304,P>0.05).Conclusions High-dose fluorine could cause varied decrease in the concentration of Hb.However,aluminum has neitherantagonistic effect nor synergistic effect on the Hb of fluorotic Rat.Soybean,selenium and Spirulina show a trend to increase fluorotic rat's Hb,but they has no evident antagonistic effect.
