Genetics of hypercalciuric stone forming diseases / 中华泌尿外科杂志

Hypercalciuria, as a common clinical feature of kidney stones, is a common feature of hereditary diseases such as idiopathic hypercalciuria, autosomal dominant hypocalcaemia, Bartter's syndrome, Dent disease, hereditary hypophosphataemic rickets with hypercalciuria, infantile hypercalcaemia, familial hypomagnesemia with hypercalciuria and nephrocalcinosis, hereditary distal renal tubular acidosis, However, the clinical phenotypes and genotypes of these hypercalciuric kidney stones have their own characteristics. We summarized the results of recent genetic studies on hypercalciuria to promote clinical screening, diagnosis and reasonable treatment.

Relationship between obesity and related indicators with insulin resistance among the residents over 50-year-old in Wuxi area / 中华内分泌代谢杂志

To analyze the relationship between obesity with related measurable indicators and insulin resistance among the residents over 50-year-old in Wuxi area.The questionnaire survey,physical examination,and relevant biochemical measurements as well as gender,age,height,body w eight,waist circumference,and hip circumference were obtained.The prevalence of obesity was 11.95％ of which 57.24％ were with central obesity,and the prevalence in male was higher than that in female(P＜0.05).With inereasing body mass index (BMI) and waist circumference(WC),the prevalence of insulin resistance increased gradually (P ＜ 0.05).Meanwhile,With the increasing HOMA-IR,the prevalence of obesity and central obesity also gradually increased (P＜0.05).BMI,WC,and waist-to-hip ratio can effectively predict insulin resistance.The cut-off point of waist circumference was 87.5 cm for male,and 84 cm for female.At the same level of body mass index,metabolic measurements in central obesity group were higher than those of non-central obesity group with the same body mass index,especially in normal weight group.The related metabolic measurements of metabolic obesity but normal weight group were mostly higher than metabolically healthy but obese group,and there were statistically significant differences in fasting blood glucose,fasting insulin,HOMA-IR and HOMA-β.Obesity,especially central obesity,is closely related to insulin resistance among residents over 50-year-old in Wuxi area.Meanwhile,waist circumference may effectively predict insulin resistance and may serve as a parameter in the occurrence of metabolic syndrome and cardiovascular diseases.
