Objective To analyze monitoring results of iodized salt and distribution characteristics of problem areas with non-iodized salt in Gansu province during 2001 - 2009 and to provide a basis to develop countermeasures to iodine deficiency disorders. Methods According to the criterion of "The National Scheme of Iodized Salt Surveillance", two levels of monitoring were carried out on production and wholesale-level(during 2001 -2007) and household-level(during 2001 - 2009). Salt iodine was determined by direct titration method (GB/T13025.7-1999), and Sichuan salt or special salt was determined with an arbitration method. Criteria for qualified iodized salt was (35 ± 15)mg/kg(20 - 50 mg/kg), and for non-iodized salt was ＜ 5 mg/kg. Results During 2001 - 2007, a total of 4900 salt samples at production and wholesale-levels were examined, with a qualification rate of 97.80% (4792/4900). Non-iodized salt rates were all below 5% in Gansu province, consumption rate of qualified iodized salt was higher than 90% after 2003. During 2001 - 2009, cities(states) with non-iodized salt problems appeared 23 times, with Linxia accounting for 39.1%(9/23), Wuwei accounting for 21.7%(5/23). During 2001 -2009, counties(districts) with non-iodized salt problem appeared 123 times, including 68 times of ethnic minorities and state poverty counties, accounting for 55.3%(68/123). During 2001 - 2005 and 2006 - 2009, ethnic minorities and state poverty counties were accounting for 49.4%(44/89) and 70.6%(24/34) in counties with non-iodized salt problem. Conclusions The quality of iodized-salt at production and wholesale level is satisfactory in Gansu province, household consumption rate of qualified iodized salt have reached national standard for eliminating iodine deficiency disorders. But ethnic minorities and state poverty counties are main regions with non-iodized salt problem,these areas will be the key areas of prevention of iodine deficiency disorders in Gansu province in the future.

This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under the feature band. Sixty five groups of phase shift spectroscopy data were obtained. According to the characteristics of cerebral hemorrhage phase shift spectroscopy under the feature hand, an effective method, B-F distribution, to diagnose the severity of cerebral hemorrhage was designed. The results showed that using MIPSS detection method under feature band, the phase shift obviously growed with increase of injection volume of autologous blood, and the phase shift induced by a 3-mL injection reached -7.750 3 degrees ± 1.420 4 degrees. B-F distribution could effectively diagnose the severity of cerebral hemorrhage. It can be concluded that the sensitivity of the cerebral hemorrhage magnetic induction detection system is improved by one order of magnitude with the MIPSS detection method under the feature band.

OBJECTIVESTo observe the change of erythropoietin (EPO) in patients of hypogonadism who received androgen replacement treatment and explore the mechanism of androgen-induced increase of red blood cells and haemoglobin.

METHODSEight patients with Klinefelter's syndrome, divided into two groups, received TU intramuscular injections of 500 mg or 1000 mg dose, respectively. After three months, seven patients received the second injection of crossover dose. Testosterone levels in serum were measured with RIA before and after the injections treatment. RBC count, impacted volume of blood cells and haemoglobin concentration were measured before treatment and 4, 8 weeks after treatment. At the same interval, EPO levels were measured with ELISA method.

RESULTSDevelopment of the secondary sex characters was improved in all patients after the TU injection. Serum testosterone levels raised significantly and reached the peak one week after the injections. Effective level of testosterone lasted for over 6 weeks. RBC count, impacted volume of blood cells and haemoglobin increased at different degrees after TU injections, but these changes were not significant in statistic(P < 0.05). The increased levels remained for 8 weeks. EPO levels were elevated significantly (P < 0.01 or 0.05) after the TU injection(Pbat > 0.05). The second injection could still make the EPO level go up.

CONCLUSIONSAndrogen replacement treatment can increase the EPO levels in patients of hypogonadism, which is one of the mechanism of RBC production increase.

OBJECTIVETo explore the correlation of ZNF217 expression to the carcinogenesis and progression of human ovarian cancer.

METHODSImmunohistochemistry and real-time RT-PCR were used to detect ZNF217 expression in human ovarian cystadenocarcinoma, ovarian cystadenoma and normal ovary tissues.

RESULTSThe expression levels of ZNF217 protein and mRNA in ovarian cystadenocarcinoma was significantly higher than those in matched ovarian cystadenoma and normal tissues (P<0.05). No significant difference was found in the expression between ovarian cystadenoma and normal ovarian tissues (P>0.05). The mRNA expression in the specimens was consistent with the protein expression of ZNF217 (P<0.05).

CONCLUSIONZNF217 gene expression is closely correlated to the occurrence and clinical stages of ovarian carcinomas, suggesting that ZNF217 can be an important candidate gene responsible for the occurrence and progression of ovarian carcinomas.
