Objective To monitor the quality changes of iodized salt and analyze its impact factor in Chongqing between 2001 and 2009. Methods Salt samples were collected according to the east, west, south,north and center locations in iodized salt production, wholesale and household sectors. Two units in iodized salt production and wholesale segment were sampled from north, south, east and west places and only 1 unit was sampled from the central place. Nine samples were collected every month in each place. If the place had less than 9 units, and then taken all the units. About resident household, 2 townships were sampled from north, south, east and west places, and 1 township was sampled from the central place, then 20 samples were collected from each township. Iodine content was detected by oxidation-reduction assay. The index of mean iodine, qualified rate from factories and wholesale, coverage rate and taking rate of qualified iodized salt in residents were calculated.Significance was analyzed by trend test, analysis of variance and X2 test. Results The qualified rate of iodized salt from the manufacturers was 92.9%(13/14) in 2001 and the rate was 100.0% each year from 2002 to 2009. The qualified rates of iodized salt from the wholesale were 88.7%(282/318) - 99.8%(431/432). The rates of 2001 and 2002 were lower than that of other years(X2 = 4.98 - 45.69, all P< 0.05 or < 0.01). The coverage rate and taking rate of qualified iodized salt in residents were 94.2% (11 154/11 841 ) - 98.9% ( 14 061/14 217), 83.5% (9 887/11 841 ) -95.8% (13 449/14 039), respectively. The rates showed an increasing tendency (F = 9.27, 26.39, all P < 0.05).The districts(counties) with qualified iodized salt consumption rate > 90% kept increasing. The mean iodine from the manufacturers and wholesale were 29.71 - 36.25, and 31.26 - 36.13 mg/kg, respectively. The iodine level showed a descending trend(F = 35.45, 140.59, all P < 0.01 ). The mean iodine level from the inhabitants were 28.84 - 30.98 mg/kg which remained stable (F = 3.05, P > 0.05 ). The iodine level from manufacturers, wholesale to inhabitants showed an descending trend(F = 38.46 - 671.23, all P < 0.01 ). Conclusions The surveillance results of iodized salt shows an increasing tendency in quality of iodized salt, eoverage rate and taking rate of qualified iodized salt. Factors that affect the quality of iodized salt is that the enterprise does not add iodine to salt strictly by the standard.

Objective To study the relationship between Couagen Ⅰ,MMP-2,TIMP-2 gene expression and atrial fibrosis during heart failure(HF)in dog.Methods Fourteen dogs were used and randomized into HF induced by ventricular tachypacing and control group.Burst atrial pacing was used to induce atrial fibrillation(AF).And the mRNA and protein level of collagen Ⅰ,MMP-2 and TIMP-2 were detected by RT-PCR and immunohistochemical technique.Tissue samples were stained with Mallory trichrome.Results Left ventricular ejection fraction (LVEF) decreased from (67.4? 6.0)% to (29.2?7.8)%,the inducible rate of AF(7/7 vs 2/7) and sustained AF(5/7 vs 0/7) increased and duration of AF stabeatrial fibrillation(SAF) [(462.12?181.43)s vs(0.57?0.57) s] prolonged significantly in HF group.Atrial fibrous tissue content and atrial size of HF group were significantly greater than the controls dogs(268.8% in lefe atria and 190.3% in right atria).The mRNA and protein level of collagen Ⅰ(56.2% and 132.2% in lefe atria,37.4% and 78.0% in right atria)and MMP-2 (100.0% and 115.7% in lefe atria,65.7% and 96.8% in right atria) increased evidently in both lefe atria and right atria,TIMP-2 mRNA decreased 46.3% in lefe atria and had no change in right atria and that its protein had no change in both atrium,whereas the ratio of MMP-2/ TIMP-2 of mRNA and protein increased markedly in both lefe atria (285.3% and 148.8%)and right atria (106.1% and 134.7%)of HF group.SAF had a positive correlation with fibrosis and the gene level of collagen Ⅰ in lefe atria,the ratio of MMP-2/TIMP-2 had a positive correlation with fibrosis and collagen Ⅰ gene level in lefe atria during HF.Conclusions The changes of collagen Ⅰ,MMP-2 and TIMP-2 gene expression appear to be a molecular mechanism of AF, and the molecular remodeling of collagen Ⅰ induced by regulation unbalance of MMP-2/TIMP-2 appears to be an important mechanism of atrial fibrosis during HF.

Objective To explore the molecular basis of familial hypercholesteraemia(FH)by analyzing the phenotype and genotype relationship through identify the low density liporotein receptor(LDL-r)gene mutation in a FH kindred.Methods A male patient of 15 years old was selected to examine the electrocardiogram,lipid.Color Doppler was used to examine heart and great vessels.The promoter region and the 18 exons of the LDL-r gene were screened by touch-down polymerase chain reaction(PCR)and DNA sequencing.Results The caro-tid intima-media thickness(IMT)was increased to 0.23 cm,while coronary flow velocity reserve(CFVR)was decreased to 1.57,and mode-rate mitral regurgitation was found in the proband.The genetic alteration G→A change at 1 448 of exon 10 causing premature stop codon(W462X).The same heterozygous nonsense mutation was also found in his father.The mutation had been reported in other Chinese patients.In vitro experiments showed that W462X mutation leads to low LDL binding and internalization ability.Conclusions The homozygous mutation(W462X)in exon 10 of the LDL-r gene were identified in the clinically heterozygous FH proband.The W462X mutation is the underl-ying cause of hypercholesterolaemia and clinical AS manifestations.W462X is recurrent mutation among Chinese FH patients.It might be a hot spot mutation in LDL-r in Chinese FH.J Appl Clin Pediatr,2009,24(1):18-20

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.
