Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

Objective: To assess the autonomic nervous impairm ent in chronic renal failure and its related factors. Methods: F orty adults were randomly selected including in-patients in the nephrology ward and healthy subjects for routine medical examination. The subjects were classifi ed into 4 groups: normal subjects(NS)，normal renal function，nitremia， uremic patients. The time domain measurements of heart rate variability(HRV) and ambula tory blood pressure were analyzed simultaneously . Results: (1) There were significant differences as compared with normal subjects in the time domain measurements of HRV in uremic group. It decreased significantly when the patient was defined as end stage chronic renal failure. There were no significan t differences between NS，normal renal function group and nitremic group. (2) Ti me domain measurements of HRV was significantly lower(P<0.05) in uremia with renal hypertension than in uremia with normal blood pressure. Conclusio n: (1) Patients with chronic renal failure(HRV) have their cardiac auton omic nervous system impaired conspicuously in the course of uremia. (2) There is a positive correlation between cardiac autonomic nervous system impairment in p atients with CRF and renal function levels. Uremia itself is an independent fact or for the impairment of cardiac autonomic nervous system. (3) Renal hypertensio n with uremia may intensify the impairment of cardiac autonomic nervous system of the patients.

In order to identify novel genes involved in spermatogenesis, testis cDNA samples from Balb/C mice of different postnatal days were hybridized with the whole mouse genome Affymetrix chip to screen the testis-specific genes. The characteristics of the selected genes were analyzed by RT-PCR as well as other bioinformatic tools. A novel differentially expressed testis-specific gene (GenBank Accession No: NM_029042) in the developmental stages of testes was identified, and named TSCPA. Cellular mapping prediction of TSCPA indicated that its protein was probably expressed in nuclei, and one putative domain (aa 332-377) was anchoring domain of cAMP-dependent type II PK. The result of subcellular localization of GFP-TSCPA fusion protein in Cos-7 cells showed that TSCPA protein was expressed in nuclei. RT-PCR analysis revealed that TSCPA was expressed specifically in mouse and human testis. TSCPA gene was expressed weakly in 21-day-old mouse testis and the expression was increased gradually from 38th day to 6th month of mouse testes. No expression of hTSCPA was found in cryptorchidism and Sertoli-cell-only syndrome patients. It was concluded that the expression profile of TSCPA in human and mice indicated that TSCPA might play an important role in spermatogenesis.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

OBJECTIVETo investigate the glutamate dehydrogenase 1 (GLUD1) gene mutation of three patients diagnosed as glutamate dehydrogenase congenital hyperinsulinism (GDH-HI).

METHODSThree patients diagnosed as GDH-HI and their parents were involved in the study. PCR-DNA direct sequencing was used to analyze the exons 6,7,10,11 and 12 of the GLUD1 gene.

RESULTSIn the first case, an R269H heterozygous mutation was found in the GLUD1 gene, with autosomal dominant inheritance. In the second case, there was a de novo S445L heterozygous mutation of the GLUD1 gene. No mutation was detected in the third case.

CONCLUSIONIn Chinese, R269H, S445L heterozygous mutation of the GLUD1 gene can lead to GDH-HI. Genetic analysis is necessary in making genetic diagnosis of congenital hyperinsulinsm.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.
