Objective To investigate the possible association of circulating components of GH-IGFs-IGFBPs system with the GHR-exon 3 genotype in idiopathic short stature (ISS) children. Methods Genomic DNA was extracted and isolat-ed from peripheral leukocytes in 108 ISS children. GHR-exon 3 polymorphism was analyzed with multiplex poly-merase chain reactions (PCR) assay. According to the results of genotype, ISS children were divided into GHRfl group and GHRd 3 group. The height and weight were recorded in two groups. The body mass index (BMI) and BMI standard deviation score (SDS) were measured. The serum levels of insulin-like growth factor (IGF)-1, IGF-binding protein (IGFBP)-3, IGF-1 SDS and IGFBP3 SDS were calculated. GH stimulation test was used to measure the serum GH peak value. Fifty-five ISS chil-dren were treated with recombine human GH [0.15 IU/(kg·d)] for three months to analyse the association of IGF-1 response of GH treatment and genotypes. Results There were 63 GHRfl and 45 GHRd3 in 108 ISS children. There were no signifi-cant differences in BMI, IGF-1, IGFBP3, GH peak, IGF-1 SDS and IGFBP3 SDS between two groups (P>0.05). Multiple stepwise regression analysis showed that age, IGFBP3, lg (BMI) and lg (GH peak) were influencing factors of lgIGF-1 (P<0.05). In 55 ISS children treated with rhGH, there were 34 cases of GHRd3. The differences of △IGF-1 and △IGF-1 SDS were higher in GHRd3 group than those of GHRfl group (n=21). Conclusion The GH sensitivity may be a risk factor in ISS children, which may not be related with GHR polymorphism.

OBJECTIVE: Investigate common deafness gene mutations in patients with severe and profound non-syndromic hearing loss in Liaoning in order to understand their hereditary etiologies and characteristics at the molecular level. METHOD: Peripheral blood samples were obtained and the DNA templates were extracted from 128 non-syndromic hearing loss patients who are sporadic in clinics. The deafness gene chip was applied to detect hot-spot deafness gene mutations including GJB2, GJB3, SLC26A4 and mitochondrial 12S rRNA. Deafness etiology questionnaires, pure tone audiometry, auditory brainstem response, tympanometry and temporal bone CT were also applied. RESULT: Various types of gene locus mutations were seen in 52 of the 128 patients (40.6%); (1) GJB2 gene mutations (n=22) included c. 235 del C homozygous mutation (n=10), c. 235 del C heterozygous mutation (n=5); c. 176_191 del 16 heterozygous mutation (n=l); c 35 del G heterozygous mutation (n=l); c. 235 del C/c. 299_300 del AT mutation (n=l), c. 235 del C/c. 176_191 del 16 mutation (n=l), c. 35 del G/c. 176_191 del 16 mutation (n=l); c. 299_300 del AT/c. 919-2 A>G mutation (n=l), c. 235 del C/c. 919-2 A>G mutation (n=l). (2) SLC26A4 gene mutations (n=30) included c. 919-2 A>G homozygous mutation (n=6), c. 919-2 A>G heterozygous mutation (n=17), c. 2168 A>G homozygous mutation (n=l), c. 2168 A>G heterozygous mutation (n=2), c. 2168 A>G/c. 919-2 A>G mutation (n=2), c. 919-2 A>G/GJB2 c. 235 del C mutation (n=2); (3) No GJB3 and mitochondrial 12S rRNA mutation. Genetic deafness was confirmed at the gene level in 24 cases (18.8%) and 28 patients (21.9%) were diagnosed as carriers of genetic deafness gene mutations. CONCLUSION Genetic deafness occupies a large population in deaf community in Liaoning. Molecular genetic screening for these mutations and genetic counseling are effective methods to prevent the occurrence of hereditary hearing loss and provide theoretical guidance.

Objective To assess the modulation of baroreflex activity by exogenous and endogenous nitric oxide (NO) in SD rats. Method The normal baroreflex sensitivity of SD rat was evaluated by intravenous (I.v.) administration of Phenylephrine (PE, 30 μg·kg-1) to elevate blood pressure. Exogenous and endogenous nitric oxide (NO) were respectively produced by I.v. Infusion of sodium nitroprusside (SNP, 10.2 μg·kg-1) and L-arginine (L-Arg, 25 mg·kg-1). And NG-nitro-L-arginine methylester (L-NAME, 10 mg·kg-1) was infused to inhibit the generation of NO. Meanwhile, baroreflex sensitivity fluctuations caused by PE were estimated. Result Compared with the normal state, L-Arg significantly reduced the baroreflex sensitivity (Gmax) and the slope coefficient τ of the blood pressure-heart rate curve [Gmax=-1.469±0.120 beats/(min·mmHg) vs. -0.664±0.080 beats/(min·mmHg), P<0.01; τ=0.0860.005 vs. 0.0490.007, P<0.05]. SNP also led to attenuation of Gmax and τ [Gmax=-1.277±0.392 beats/(min·mmHg) vs. -0.943±0.297 beats/(min·mmHg); τ=0.074豹0.027 vs. 0.071±0.023] but the changes were not significant. In contrast to L-Arg and SNP, L-NAME induced raise of Gmax and τ [Gmax=-0.705±0.231 beats/(min·mmHg) vs. -1.065±0.200 beats/(min·mmHg); τ=0.0450.011 vs. 0.0590.026], however, they were statistically insignificant. Conclusion The results demonstrated that NO imposes effect on baroreflex activity, and the behaviors of exogenous and endogenous NO are different. Endogenous NO may be involved in the regulation of autonomic nervous system via central nervous system or carotid sinus, and inhibits the baroreflex sensitivity.

Objective To investigate the clinical efficacy of percutaneous transhepatic insertion of biliary stent (PTIBS) combined with radioactive seed implantation in treating malignant biliary obstruction. Methods A total of 38 patients with malignant biliary obstruction were enrolled in this study. Radioactive 125I seed was used, and each 125I seed was 4.5 mm in length and 0.8 mm in diameter. The 125I seeds were placed in a catheter to prepare the 125I seed- strip. PTCD was carried out first, then percutaneous catheterization was performed and a guide- wire was inserted through the catheter until it passed the obstructed biliary segment. The obstructed segment was dilated by a balloon - catheter, which was followed by PTIBS. An 8 - 10 F drainage - catheter was placed into the biliary duct through the stent. Finally, guided by fluoroscopy the catheter with the 125I seed- strip was inserted via the drainage- catheter to the area that was planned to be radiated. The external drainage- catheter was wrapped and fixed to the skin, or was imbedded under the skin. Results Of the 38 patients with malignant biliary obstruction, successful PTIBS combined with radioactive seed implantation was accomplished in 36 patients. After the treatment, the serum bilirubin level fell to normal or near normal range in all patients (P < 0.05). No obvious side effects were observed. Conclusion For the treatment of malignant biliary obstruction, percutaneous transhepatic insertion of biliary stent combined with radioactive 125I seed - strip implantation is a safe and effective method.
