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.

Objective To explore the effect of the gene silencing of phosphatidic acid-preferring phospholipase A1 (PA-PLA1) on insulin secretion in mouse insulin-secreting cell line MIN6. Methods The siRNA expression vector of mouse PA-PLA1 gene targeting was constructed using mouse PA-PLA1 mRNA sequence available in GenBank, and MIN6 cells were transfected with the vector. Fluorescence quantitative PCR and Western-blotwere applied to screen efficient RNAi-vector. After transfection with obtained efficient RNAi-vectors for 48 hours, glucose-stimulated insulin secretion experiments were conducted, and the changes of insulin secretion were examined. Results Four siRNA expression vectors of mouse PA-PLA1 gene targeting were confirmed to be successfully constructed by the analyses of enzyme cleavage and sequencing. The results of fluorescence quantitative PCR and Western blot analyses indicated that the siRNA expression vectorpGPU6-PA-PLA1-1885was the most effective RNAi-vector in the four vectors. The expression levels of the PA-PLA1 mRNA and protein of the MIN6 cells transfectedwith pGPU6-PA-PLA1-1885 decreased to 46.3% and 33.9% of that of the control, respectively, and meanwhile the insulin secretion levels of the cells decreased to 65.0% of that of the control (P < 0.05). Conclusion The gene silencing of phosphatidic acid-preferring phospholipase A1 might decrease insulin secretion in MIN6 cells.

Objective To investigate the prognosis of patients with Kawasaki's disease complicated with coronary artery lesion and to provide evidence for diagnosis and treatment of these patients. Methods This study was conducted during January 2002 to June 2007. All patients diagnosed as Kawasaki's disease complicated with coronary artery lesions were from the Affiliated Hospital of Guilin Medical College, the Second People's Hospital of Guangxi Province and Guilin Women and Childrens' Hospital. All cases were echocardiogram examined in month 3, 6, 12, 24 and 36 in the purpose of observing the morphology of coronary artery. The study subjects were re-categorized to the groups of mild, moderate dilatation of coronary artery and giant coronary aneurysm, based on the severity of coronary artery lesion. The results of these results of the three groups were compared. Results Eighty-four cases in the mild group, 27 cases in the moderate group and 8 cases in the giant coronary aneurysm. The recovery cases were 23 (27%), 3 (11%) and 0 in the 3 groups respectively at month 3. The above numbers were 44 (52%), 8 (30%) and 0 respectively at month 6.The numbers were 69(82%), 13 (48%) and 1 (13%) at month 12. The numbers were 78 (93%), 19 (70%), 3 (38%) at month 24. The numbers were 82(98%), 20(74%) and 4(50%) at month 36. Thirteen patients were treated with adenosine-triphosphate (ATP) stress echocardiography examiantion, 5 patients were evaluated by coronary angiography,and 4 patients were tested by 64-slice CT coronary reconstruction. Part of the patients were found to have coronary stenosis or occlusion. Conclusion Patients of Kawasaki's disease often have concurrent coronary artery lesions. Patients with mild dilatation of the coronary artery are the most commonly seen and have the best prognosis. On the contrast, patients with giant coronary aneurysm are the lest common situation and is the worst in prognosis. Part of them will develop coronary artery stenosis or occlusion in late stage which may lead to ischemic heart disease. We should stress on close follow-up of patients with Kawasaki's disease complicated with coronary artery lesion. Appropriate and timely treatment will increase their clinical outcomes.

To explore the growth and development and analyze the quality of the parthenocarpy fruit induced by exogenous hormones of Siraitia grosvenorii. the horizontal and vertical diameter, volume of the fruit were respectively measured by morphological and the content of endogenous hormones were determined by ELISA. The size and seed and content of mogrosides of mature fruit were determined. The results showed that the fruit of parthenocarpy was seedless and its growth and development is similar to the diploid fruit by hand pollination and triploid fruit by hand pollination or hormones. But the absolute value of horizontal and vertical diameter, volume of parthenocarpy fruit was less than those of fruit by hand pollination, while triploid was opposite. The content of IAA, ABA and ratio of ABA/GA was obviously wavy. At 0-30 d the content of IAA and ABA of parthenocarpy fruit first reduced then increased, content of IAA and GA parthenocarpy fruit was higher than that of fruit by hand pollination. Mogrosides of parthenocarpy fruit was close to pollination fruit. Hormones can induce S. grosvenorii parthenocarpy to get seedless fruit and the fruit shape and size and quality is close to normal diploid fruit by hand pollination and better than triploid fruit by hormone or hand pollination.

Cerebral cysticercosis is the most common worldwide parasitic infection of the central nervous system. Intraventricular involvement is apparent in 15% to 28.8% of cases with neural compartment infestation.' Although different forms of the disease (parenchymatous, subarachnoid, and mixed form ) have been treated successfully with chemotherapy, direct surgical excision of simple cystic lesions appears to be an adequate primary therapeutic strategy in the majority of intraventricular forms. In recent years, however, some authors have advocated the use of anthelmintic treatment in all cases of intraventricular cysts so that surgical procedures of the posterior fossa and their potential complications can be avoided. The strict definition for managing the spectrum of intraventricular infestation remains controversial. We present our experience in the treatment of a patient with primary isolated intraventricular cysticercosis.
