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.

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.

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.

Objective To observe the combined poisonous effects of fluoride and aluminum on sex hormone of male rats.Methods Sixteen weaned SD healthy male rats aged two week were selected and divided into control group,aluminum group,fluoride group,fluorine-aluminum group,four rats in each group.All rats in the experimental groups were fed with corn collected from the prevailng areas containing different fluorine contents respectively for 90 days.Serum testosterone(T)and estradiol(E2)were detected.Results Compared separatelv with the control group[(3.317±0.635)μg/L],serum T level of fluorine-aluminum group[(15.994±6.558)μg/L]was higher(P＜0.05),but aluminum[(8.134±3.134)μg/L]and fluorine[(1.868±0.367)μg/L]groups had no significant differences(P＞0.05).Compared separately with the control group[(0.319±0.072)nmol/L],E2 level of the fluorine group[(0.172±0.030)nmol/L]being lower(P＜0.05),and it was not significant differences(P＞0.05)in the control group when compared with aluminum group[(0.282±0.012)nmol/L],and fluorine-aluminum group[(0.265±0.047)nmol/L].Fluorine and aluminum interacted with each other(F=9.82,P＜0.05).Conclusion The combined poisonous effects of fluorine and aluminum may influence sex hormone levels of male rats.

OBJECTIVETo analyze the consistency of evolution condition between HA gene and the whole genome of influenza virus subtype A/H3N2 strains isolated in Zhejiang province from 1998 to 2009, and to study the potential antigenic region on the whole genome.

METHODSThe sequences of whole genome of 19 Zhejiang influenza virus isolates circulated from 1998 to 2009, which conserved by influenza laboratory of Zhejiang Provincial Centre for Disease Prevention and Control, were amplified using RT-PCR assays. The obtained sequences were used to conduct phylogenetic analysis with 10 contemporaneous vaccine strains. Three methods, including comparison of the amino acid substitutions, calculation of the entropy value and the filtering of positive selection sites, were used to confirm the mutable sites on each gene.

RESULTSThe whole genome of influenza virus subtype A/H3N2 was 4466 amino acids in length, with 137 stable mutations. The 144, 158 aa of HA gene mutate four and three times respectively; 93, 143, 307, 370, 372 aa of NA gene and 450 aa of NP gene mutate twice, and there were 29% (12/41) and 77% (24/31) mutations of HA and NA genes occurred on the non-epitope regions respectively. Analysis of the entropy value suggest that many amino acid sites on the non-epitope regions were prone to mutation, including 3, 225, 361 aa of HA gene; 93, 143, 147, 150, 372 aa of NA gene; 113, 576, 586 aa of PB1 gene; 101,256, 382, 421, 437 aa of PA; 377, 450 aa of NP gene; 218 aa of M1 gene and 31 aa of M2 gene.

CONCLUSIONBased on the whole genome of influenza virus subtype A/H3N2 strains isolated in Zhejiang province in 1998 to 2009, there may be several unknown or new antigen sites existing on the non-epitope regions of HA and NA genes and parts of internal genes. The phylogenetic tree constructed based on the complete sequence was more comprehensive than on the HA gene to reflect the genetic relationship and law of evolution among the influenza virus strains.
