Thanks to the communication between hospital information systems and the mobile phone system,the doctor in charge can contact his/her patient by mobile phone.This creates an early warning mechanism for critical results of laboratory tests such as clinical laboratory,radiological,ultrasound and ECC tests,in which the doctor in charge can be advised immediately of any critical results found in laboratory tests by SMS.This mechanism enables clinicians to acquire critical information,identify medical risks and minimize medical errors.

Even though mutations in LMNA have been reported in patients with typical dilated cardiomyopathy (DCM) and atrioventricular block (AVB) previously, the purpose of this study was to disclose this novel genetic abnormality in one Chinese family with the atypical phenotype of progressive AVB followed by DCM with normal QRS interval. Genome-wide linkage analysis mapped the AVB gene in this family to a marker at chromosome 1q21.2, where the LMNA gene was located. Direct DNA sequence analysis revealed a heterozygous G to A transition at nucleotide 244 in exon 1 of LMNA, which resulted in an E82K mutation. The E82K mutation co-segregated with all affected individuals in the family, and was not present in 200 normal controls. Further clinical evaluation of mutation carriers showed that 5 of 6 AVB patients exhibited mild DCM with a late onset of age in the fourth and fifth decades. Ejection fractions were documented in 5 patients with DCM, but 4 showed a normal value of [Symbol: see text]50%. Echocardiography showed that atrial dilatation occurred earlier than ventricular dilatation in the patients. This study suggests that progressive AVB with normal QRS interval and accompanying DCM at later stages may represent a distinct type of DCM. The molecular mechanism by which the E82K mutation causes AVB as the prominent phenotype in DCM may be a focus of future studies.

Objective To evaluate iodine nutrition status and vitamin D level in hyperthyroidism patients and explore their impacts on the pathogenesis of hyperthyroidism.Methods Totally 116 inpatients of hyperthyroidism were tested for serum thyroid function,urine iodine and serum 25-OH-D.Median and component ratio of urine iodine and 25-OH-D were used to evaluate nutrition status.Results The median of urine iodine was 224.9 μg/L,while the component ratio of iodine excessive-intake was 59.48％ (12.93％ in excessive group and 46.55％ in sufficient group).The median of vitamin D was 7.19 ng/ml while as deficiency group accounted for 93.2％ in hyperthyroidism patients.Conclusions Attention should be paid to excessive intake iodine in hyperthyroidism patients.Vitamin D supplementation is important for treating hyperthyroidism and maintaining the health of skeleton and muscle.
