Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

OBJECTIVETo explore the changes of serum sexual hormone levels in male hyperthyroidisms before and after treatment.
METHODSCompared with the control group, the serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) and estradiol (E2) of 68 cases of male hyperthyroidisms before and after treatment were detected by chemiluminescence immunoassay technique, and then statistical analysis was performed.
RESULTSThe serum T and E2 levels of male hyperthyroidisms were significantly higher than those of the control group before treatment (P < 0.005); while no significant difference in FSH and LH levels existed between the patients and the control group (P > 0.05). There was no difference in FSH, LH, T and E2 levels between patients and the control group after treatment (P > 0.05).
CONCLUSIONThere are sexual hormone metabolism disorder in hyperthyroidism men, and the increasing serum T and E2 levels are only to adapt the high metabolism environment, and the changes of hypothalamus-pituitary-gonadal axes. Along with the control of hyperthyroidism, the sexual hormone levels return to normal.

Objective: The current study was designed to evaluate the clinical application of radioimmunoimaging(RII) for lymph node metastasis in esophageal carcinoma. Methods:1)131I was used to label McAb G9(specific to cellular membrane antigen of human esophageal carcinoma) and form labeling compound 131I-G9. Administration of 131I-G9 in esophagus submucosally with a specific injector for the purpose of submucosal injection via endoscopies in preoperative patients with squamous cell carcinoma of thoracic esophagus followed by RII. 2)The samples of dissected lymph node were used for detection of radioactivity. Results: 1)The pictures at 48 h showed that small radioactivity concentrated dots appeared dispersedly in mediastinum and upper abdomen around esophagus and cardiac gastric. The lymph nodes were considered metastatic in above regions. 2)The pathological results of the lymph nodes dissected compared to the RII result. The metastatic lymph nodes were found in the regions of dispersedly concentrated radioactivity, while no metastatic lymph nodes could be found in the radioactivity free regions. 3)After counting for radioactivity, lymph node metastases showed higher antibody uptake than the non-metastases lymph nodes. The difference was statistically significant. Conclusion: 131I-G9 may be used to locate metastatic lymph nodes in patients with esophageal carcinoma.

OBJECTIVES: In Fujian Province, China, gastric cancer is one of the leading causes of mortality among all malignant tumors. Nanjing county and Minqing county are located in inland Fujian and have similar general demographics. However, the adjusted mortality rate of gastric cancer in Minqing was found to be much higher than that in Nanjing. We sought to explore factors associated with this increased risk of gastric cancer between the two counties. METHODS: We recruited 231 and 224 residents from Nanjing and Minqing, respectively, and analyzed differences between their dietary habits, Helicobacter pylori infection rates, and concentrations of serum pepsinogen I, pepsinogen II, gastrin-17, and ratio of pepsinogen I:II. RESULTS: Subjects in Minqing had more first-degree relatives who had been diagnosed with upper gastrointestinal tumor, more unhealthy dietary habits, a higher Helicobacter pylori positive rate, and greater proportion of abnormal serum gastrin-17 than those in Nanjing did. CONCLUSIONS: The factors that differed between these two counties might indicate that residents in Minqing have a higher risk for developing gastric cancer than those in Nanjing do.

OBJECTIVETo identify the mutation of spondyloepiphyseal dysplasia tarda (SEDL) gene in a large Chinese family with X-linked spondyloepiphyseal dysplasia tarda and to make a discussion on the pathogenesis of SEDL at the molecular level.
METHODSIn two patients, four exons comprising the SEDL open reading frame as well as their exon/intron boundaries were analyzed by bi-directional direct sequencing of PCR products. The sequencing results were compared against the normal sequences in GenBank to find the mutation. Then the mutation was identified in other members of the family.
RESULTSA nucleotide substitution of the splice acceptor in SEDL intron 2, IVS2 -2A-->C,was detected in two affected individuals (IV(15) V(3)) in the Chinese family with SEDL, but no sequence change occurring on exons 3-6 was detected. The transversion was also identified in four heterozygous carriers. The mutation was not found in two unaffected male individuals and fifteen normal controls. Furthermore, four potential carriers were identified in the family.
CONCLUSIONThe mutation IVS2 -2A-->C of SEDL gene was firstly determined in the world. The change of the splice acceptor in SEDL intron 2 may cause skipping of exon 3 which is responsible for the disease. Molecular diagnosis can be made by detecting the mutation.

OBJECTIVETo examine the association of activation of calcium-sensing receptors (CaSR) with apoptosis in cardiomyocytes under simulated ischemia/reperfusion.
METHODSVentricular cardiomyocytes of neonatal rats were incubated in ischemia-mimetic solution for 2 h, then re-incubated in normal culture medium for 24 h to establish a model of simulated ischemia/reperfusion (I/R). Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL assay). The expression of CaSR mRNA was detected by reverse transcriptase polymerase chain reaction (RT-PCR). The expression of Caspase -3 and Bcl-2 was detected by Western blotting.
RESULTThe simulated I/R enhanced the expression of CaSR and cardiomyocyte apoptosis. GdCl(3), a specific activator of CaSR, further increased the expression of CaSR and cardiomyocyte apoptosis, along with upregulation of Caspase-3 and downregulation of Bcl-2.
CONCLUSIONCaSR is associated with I/R injury and apoptosis in neonatal rat ventricular cardiomyocytes via suppressing Bcl-2 and promoting Caspase -3 expression.
