Objective To investigate the relationship between serum ferritin and p-cell function,insulin resistance in elderly patients(age>60 years)with type 2 diabetes and impaired glucose tolerance.Methods Total 1143 patients with type 2 diabetes,448 patients with impaired glucose tolerance(IGT),and 2 950 subjects with normal glucose tolerance(NGT)were recruited for the measurments of height,weight,serum triglyceride(TG),total cholesterol,fasting plasma glucose(FPG),fasting insulin(FINS),postprandial 2 h plasma glucose(2hPG),and serum ferritin.Homeostasis model assessment of insulin resistance(HOMA-IR)and QUICK index were used to estimate insulin resistance,and homeostasis model assessment of β cell function(HOMA-p)and disposition index(DI)to evaluate p-cell function.Results The results showed that the level of serum ferritin was significantly higher in type2 diabetes mellitus group than NGT group(P<0.01).HOMA-IR was gradually increased,and HOMA-β,QUICK,and DI decreased from NGT to IGT,type 2 diabetes mellitus groups(all P < 0.05).Spearman and partial correlation analysis showed that partial adjustment for age and sex,serum ferritin was positively associated with FPG,2hPG,TG,FINS,and HOMA-IR,and negatively associated with HOMA-β,QUICK,and DI.Stepwise regression showed that serum ferritin was associated with QUICK,BMI,and TG.Conclusion The results suggest that iron overload exists in elderly patients with type 2 diabetes.With increasing serum ferritin level,insulin resistance increases and p-cell function decreases in the elderly patients with abnormal glucose metabolism.

Blood C-peptide,first-void fasting urinary C-peptide/creatinine ratio ( UCPCR ),second-void fasting UCPCR,and 24 h urinary C-peptide (UCP) were determined in 90 type 2 diabetics and 30 health volunteers.The results showed that first-void fasting UCPCR and second-void fasting UCPCR were positively related to 24 h UCP and the index of islet β-cell function( all P＜0.01 ).

Objective To investigate the adiponectin levels in non-obese first-degree relatives (FDR)of type 2 diabetic subjects and its relation to insulin sensitivity and the intima-media thickness of the common carotid artery (IMT) during 5-year follow-up. Methods Fifty-three FDR subjects and 37 control subjects who were free of type 2 diabetes were enrolled. Plasma adipenectin, lipid profile, blood glucose, fasting insulin, and blood pressure were determined at baseline and after 5-year follow-up. IMT and endothelial-dependent vasodilation (EDVD) were measured by high-resolution B-mode ultrasound imaging. Homeostasis model assessment was used to evaluate insulin resistance (HOMA-IR)and β-cell function (HOMA-β). 29 FDR subjects and 20 control subjects completed the follow-up. Results Comparing with the control, plasma adiponectin levels in non-obese FDR subjects were lower at baseline [(10.06±5.79)vs (14.43±7.91) mg/L, P< 0.05]. Plasma adiponectin were decreased 24.0% in non-obese FDR and 36.7% in control duning 5 year follow-up (both P<0.05). Adiponectin levels were negatively correlated with waist-to-hip ratio (r = -0. 397), fasting blood glucose (r = -0. 373), IMT (r = -0. 372), and HOMA-IR (r=-0. 40)in the non-obese FDR. After adjusting other relevant risk factors,adiponectin was associated with age, high-density lipoprotein-cholesterol, and IMT in multiple regression analyses in non-obese FDR group. In the control group, a similar analysis revealed that low-density lipoprotein-cholesterol and IMT explained 25% of the variability in the adiponectin concentration. Conclusion Plasma adiponectin levels were decreased after 5 years in both non-obese FDR and control subjects. Decreased adiponectin level may be related to IMT increment.

Lymphocyte subsets in peripheral blood and function of CD4+CD25+ regulatory T cells(Tregs) were assayed in patients during different periods of Graves' disease ( GD ).Breakdown of Tregs' function lead to the wild proliferation of CD4+T lymphocyte,and may play an important role in the pathogenesis of GD.It is difficult to fully restore the Tregs' function to normal after successful medication in Graves' disease,this phenomenon may lead to easy relapse of GD.

This paper reports a case of a male patient with diabetes for more than 20 years who came to see doctor due to weakness, poor appetite and significantly elevated blood glucose. At first, it was considered that the poor blood glucose control of diabetes was the reason, and the possibility of diabetes related complications already existed. Hospital routine examination indicated a globulin increase and immunologic examination indicated that IgM was mainly increased. Subsequent imageological diagnosis revealed a small amount of bilateral pleural effusion, and after 2 weeks of hypoglycemic treatment, the blood glucose was significantly improved, but the symptoms still existed. In combination with the patient′s laboratory examination, considering the combination of blood system diseases, the hematology department was invited for consultation. Immunoelectrophoresis, bone marrow cytology, and flow cytometry were further conducted, and the patient was diagnosed with Waldenstrom macroglobulinebia. Bortezomib + dexamethasone regimen was given for chemotherapy. Currently, the patient has received 1 course of chemotherapy, and the symptoms of poor appetite were significantly improved. Coexistence of diabetes mellitus and Waldenstrom macroglobulinebia is very rare in clinical practice, and it is easy to be misdiagnosed as a complication of diabetes mellitus, both of which can be manifested as poor appetite, weakness, peripheral neuropathy and other symptoms. When diabetic patients have abnormal immunoglobulin increases and other abnormal test results that cannot be well explained by diabetes, other potential disorders, such as hematological diseases, should be considered to avoid missed diagnosis.

Objective To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People′s Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m2, (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m2, (6.7±1.6) mmol/L, (6.1± 1.2) mmol/L; (22±3) kg/m2, (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM ( OR=2.799, 95% CI :1.186-6.604; P<0.05). Conclusion The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

Objective To investigate the threshold values of insulin resistance ( IR) assessed by homeostasis model and the prevalence of IR in elderly people over 60 years old in Minhang district of Shanghai, and to evaluate the relationship between IR and metabolic syndrome ( MS) . Methods A total of 3003 elderly people aged 60 and over in the Jiangchuan community of Minhang District, Shanghai, were recruited, including 1286 males and 1717 females. Blood pressure, waist circumference, BMI, blood routine, serum creatinine, blood lipids, glucose, and fasting insulin were measured in all populations studied. Homeostasis model assessment ( HOMA) was used to estimate IR, and MS, and defined according to three diagnostic criteria including NCEP-ATPIII, IDF, and CDS. Results 75th percentile, 80th percentile and 90th percentile of HOMA values in 268 subjects with normotensive and normal BMI, glucose tolerance were considered as the thresholds of IR. The cut-off values were 2. 78, 3. 01 and 3. 56, respectively. And the prevalence of IR were 50. 0％, 42. 1％, and 27. 2％, respectively. IR level was significantly higher in people with MS. Based on the receiver operating characteristic ( ROC ) curve analysis, HOMA-IR and QUICKI index predicted MS well, and the optimal thresholds for diagnosing MS of HOMA-IR were 3. 17 for NCEP-ATPⅢ, 3. 02 for IDF and 3. 03 for CDS. BMI was the best factor for diagnosing IR among different MS components. Logistic regression analysis showed that gender, WC, BMI, SBP, HDL-C, TG, FBG and WBC were independent risk factors for IR. FBG≥5.84 mmol/L was the most dangerous factor of IR (OR=3.603,P<0.01), followed by WC≥85.4 cm(OR=2.152, P<0.01) and BMI≥24.6 kg/m2(OR=2.150,P<0.01). Conclusion The cut-off values of IR estimated by HOMA and the prevalence of IR were higher in elder subjects than other populations. IR was significantly positively correlated with MS. Excluding the conditions that insulin measurement were affected by external factors, HOMA-IR may predict the risk of MS. The components of MS were relative specific measurements of IR, FBG, BMI and WC were important risk predictors of IR in the elderly.

Objective:To Investigate comprehensive predictive ability of first-trimester complete blood count combined with maternal characteristics for gestational diabetes mellitus (GDM).Methods:From May 2015 to July 2018, 1 412 pregnant women were retrospectively screened at the Fifth People′s Hospital of Shanghai, Fudan University. We recruited 258 women who developed GDM and 1 154 women who had normal glucose level during pregnancy. At the first visit, clinical data and complete blood count result were obtained. GDM prediction models were established through logistic regression analysis of GDM related risk factors and the prediction abilities of each model were compared.Results:Logistic regression analyses identified age, pre-pregnancy body mass index, previous GDM history, family history of diabetes mellitus, the neutrophil-to-lymphocyte ratio, leukocyte, neutrophil, and monocyte counts were significantly independent predictors of GDM. In the entire cohort, the predictive ability of neutrophil and monocyte counts together with maternal basal characteristics model for the development of GDM [areas under the receiver operating characteristic curve (AUC-ROC)=0.809, integrated discrimination improvement (IDI)=0.056, P=0.001] was the best among various models (basal characteristics model, AUC-ROC=0.753; Monocyte count+ basal characteristics model, AUC-ROC=0.764; neutrophil count + basal characteristics model, AUC-ROC=0.775). Similar results obtained by the same way in all pregnant women without previous GDM history. Conclusion:It could improve the prediction of GDM with model incorporated maternal characteristics and first-trimester neutrophil and monocyte counts.
