1.Effect of early application of liraglutide on visceral obesity
Chinese Journal of Endocrinology and Metabolism 2014;30(10):872-875
Visceral obesity is closely related to development of insulin resistance,metabolic syndrome,type 2 diabetes mellitus,and cardiovascular disease.Visceral obesity leads to increased insulin resistance,which is an important risk factor for the development of type 2 diabetes mellitus.Weight loss,especially reduction of visceral adipose,can improve insulin sensitivity effectively,and thereby reduce the risk of obesity-related type 2 diabetes mellitus and cardiovascular disease.Studies have confirmed that liraglutide,as an analogue of human glucagon like peptide-1 (GLP-1),when used early in type 2 diabetes patients with obesity,can not only control glycemia and protect β-cells,but also significantly lose weight,and its benefit on weight is mainly based on the reduction of visceral adipose.Therefore,early application of liragtutide in type 2 diabetes with obesity will provide a new choice for the treatment of type 2 diabetes mellitus.

Chinese Journal of Clinical Nutrition 2010;18(2):72-76
Objective To analyze the hospitalization rates of diabetic patients in different departments in different years and compare the differences in hospitalization costs, length of stay, and mortality between diabetic and non-diabetic patients. Methods The clinical data of hospitalized patients from 1995 to 2009 in different departments of Peking Union Medical College Hospital were retrospectively analyzed. Patients were divided into three groups by calendar period (every five years) and into four groups by ages. Results A total of 500 523 patients were enrolled in this study. From 1995 to 2009, the hospitalization rates of diabetic patients increased from 2.85% to 7.65% , especially among patients who were treated in the departments of cardiology, ophthalmology,and vascular surgery. In 2009, the hospitalization rates of diabetic patients in the three departments were 29.36% , 24. 51% , and 21.25 % , respectively. The length of hospital stay was significantly longer among diabetic patients than among non-diabetic patients (P < 0. 001). The total hospital costs were also significantly higher among diabetic patients than among non-diabetic patients in all the period and age groups (P < 0.01 or P <0.001)except in 2000-2004 group and 2005 - 2009 group in 0 - 18 years group (P >0. 05). The hospital cost per day in diabetic patients was significantly lower than that in non-diabetic patients in all the period and age groups (P < 0. 05, P < 0. 01 or P < 0. 001)except in 1995-1999 group in over 65 years group (P > 0.05). The mortality rate of diabetic patients in the 1995-2004 in 0-18 years group was zero, and the mortality rates were not significantly different between diabetic patients and non-diabetic patients in 2005 -2009 group in 0-18 years group (P >0.05), and were significantly higher in diabetic patients than in non-diabetic patients in all other period and age groups (P <0.01 or P < 0. 001). Conclusions Diabetic inpatients tend to have a longer hospital stay, higher hospitalization rate, higher hospital costs, and higher mortality rates. A hospital-wide diabetes management mode should be developed to optimize its treatment.

Objective To understand the application of dietary supplements among adult patients with type 2 diabetes mellitus (T2MD) in two areas of China. Methods A total of 615 T2MD patients were recruited from three hospitals in Beijing and Shenyang, with convenience sampling for the study using self-reported questionnaires. Data were statistically analyzed. Results Overall 34. 8% of the participants (22.5% in Beijing and 45.5% in Shenyang, respectively) reported ever use of at least one dietary supplement in the past 12 months. The most commonly used supplement was royal jelly ( 16. 1% ), followed by vitamins ( 10. 1% ), calcium (8. 8% ),fish oil (7. 3% ), spirulina (3.9%), and lecithin (2. 3% ). Except that royal jelly was used for complementary treatment for T2MD, most of the other supplements were used for improving their body defense. In addition, more than 20 other health dietary supplements were also used for diabetes-related conditions in 8. 5% of the participants surveyed. The participants' main sources of information about dietary supplements were from mass media or recommendations by relatives and friends. About half of supplements users perceived that the dietary supplements were effective. The application of dietary supplements was associated with gender, educational background, living area,perceived burden of medical cost, stage of diabetes, comorbidity, and body mass index (BMI) of the patients ( all P <0. 05). Conclusions Dietary supplements are widely used among T2MD patients in Beijing and Shenyang.The types of these dietary supplements are diverse and lack professional instructions. It is recommended that information on dietary supplements should be included in diabetes education.

Objective To evaluate the value of continuous glucose monitoring system (CGMS) in the gestational patients with impaired glucose regulation. Methods The glucose level in the subcutaneous tissue was monitored by CGMS for 3 days in 6 patients with gestational diabetes mellitus (GDM) and 6 patients with gestational impaired glucose tolerance (GIGT). The fluctuation coefficient of blood glucose, percentage of hyperglycemic time, and percentage of hypoglycemic time were calculated. Results As shown by CGMS, the fluctuation coefficient of blood glucose, mean glucose level, percentage of hyperglycemic time, percentage of hypoglycemic time, mean fasting blood glucose, and mean postprandial blood glucose (PBG) levels were not significantly different between GDM group and GIGT group (P > 0. 05). The time for reaching the peak PBG level ranged 90-120minutes in both two groups (P > 0. 05). No sensor-related adverse events were noted. Conclusions It is safe to apply CGMS sensor in pregnant women. The blood glucose profiles are comparable between GDM and GIGT patients by CGMS; therefore, control of blood glucose should be equally strict in patients with GIGT as those with GDM.

Primary hyperparathyroidism (PHPT) in children is a rare condition,co-existing with vitamin D deficiency can lead to more diagnostic uncertainty.Here we report a case of a boy with PHPT complicated with vitamin D deficient rickets.The diagnosis and treatment of this patient was analyzed against literature review to summarize evidence-based clinical features of PHPT in children.We found that compared with adult PHPT,PHPT in children is associated with severer symptoms,higher serum calcium level,lower parathyroid hormone,preponderance of single adenoma in pathology,and higher cure rate of surgery.Co-existence of osteomalacia may induce reduction of the serum calcium level to the normal range,but cause more severe bone lesions.
