Objective To explore the therapeutic effect of hyperbaric oxygen therapy (HBO) in the treatment of neuropsychological disorders in senile patients with type 2 diabetes mellitus combined with cerebral infarction. Methods A total of 70 senile patients with type 2 diabetes mellitus combined with cerebral infarction were randomly divided into two groups: treatment group receiving HBO plus routine medicine treatment and control group receiving routing medicine treatment only. A suit of senile neuropsychological tests was administered pre and post treatment by an experienced psychometrician who was blinded to treatment group assignments. Results Neuropsychological disorders were improved partly in control group while the efficacy in treatment group was markedly improved(P<0.01). Spearman rank correlation analysis revealed that the improvement degree of neuropsychological disorders was positively correlated with hyperbaric oxygen therapy (HBO) (r= 0.502,P<0.05), the time of test before therapy (r=0.260, P<0.05) and the time of test after therapy (r=0.386, P<0.05), and was negatively correlated with hyperlipoidemia (r=-0.261, P< 0.05), glycosylated hemoglobin(GHbAlc) (r=-0.321,P<0.05) and body mass index(BMI) (r= 0.360,P<0.05). Multiple stepwise regression analysis showed that HBO and hyperlipoidemia were the independent predictors for the improvement degree of neuropsychological disorders. Conclusions HBO is an efficacious way to treat neuropsychological disorders in senile patients with type 2 diabetes mellitus combined with cerebral infarction.

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.

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.

Objective To investigate the maternal and fetal outcomes of pregnant women with subclinical hypothyroidism, and clinical observation of thyroxine replacement. Methods From March 2014 to March 2015, the clinical records of 216 women with subclinical hypothyroidism(including 166 cases with thyroxine replacement), and hypothyroidism(n=69)during pregnancy who delivered at our hospital were reviewed. The maternal complications and neonatal outcomes were compared with 406 healthy women who delivered during the same period. Results The age, number of fetus, and morbidity rate of gestational hypertension were without significant differences in those groups. The morbidity of gestational diabetes in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(13.4%, 17.4% vs 0.2%, P<0.05). The rate of thyroid peroxidase antibody and thyroglobulin antibody positive in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(26.9%, 23.2% vs 9.9%; 15.7%, 23.2% vs 8.1%, all P<0.05). No matter treated or not treated in subclinical hypothyroidism group, the preterm birth, Apgar score, low birth weight, birth defects, and infant congenital hypothyroidism were without significant differences as compared to the control group(P>0.05). Further compared those between treated and untreated subclinical hypothyroidism, the results were also without significant difference(P>0.05). Conclusions Subclinical hypothyroidism had no significant influence on pregnancy outcomes and perinatal events. Thyroxine replacement in subclinical hypothyroidism pregnant women also had no significant influence on pregnancy outcomes and perinatal events.

Objective To explore whether adiponectin receptor 1/2(AdipoR1/R2)mediates berberine to alleviate renal lipid toxicity in mice with diabetic kidney disease.Methods C57BLKS/J db/db mice and db/m mice were selected and divided into 4 groups,with 8 in each group.db/db mice and db/m mice were given berberine(150 mg·kg-1·d-)or placebo by gavage for 12 weeks,respectively.After intervention,blood glucose,blood lipids,urinary microalbumin/creatinine ratio and urinary albumin excretion rate were determined.Kidney tissues were taken for pathological examination,and oil red O staining,immunohistochemistry,ELISA and Western blotting were used to examine lipid deposition,AdipoRl/R2 expression and fibrosis markers expressions,etc.,respectively.The human glomerular endothelial cell line(HGEC)was used to verify the role of AdipoR1/R2 in berberine alleviating renal lipid toxicity.Results After berberine intervention,the body weight,blood glucose,lipids,proteinuria,renal lipid deposition,and renal pathological changes decreased in db/db mice(P＜0.05);the expressions of AdipoR1 and AdipoR2 increased,expressions of TGF-β1 and Col-Ⅳ decreased,and the expressions of PPAR-α and p-AMPK increased in kidney tissue of db/db mice(P＜0.05).In high-fat cultured HGEC cells treated with berberine-treated db/db mouse serum,the expressions of TGF-β1 and Col-Ⅳ decreased,while the expressions of PPAR-α and p-AMPK increased(P＜0.05);after AdipoR1/R2 on HGEC cells were silenced,the expressions of TGF-β1 and Col-Ⅳ increased,while the expressions of PPAR-α and p-AMPK decreased(P＜0.05).Conclusions Berberine can reduce renal lipid toxicity in diabetic nephropathy mice,and adiponectin receptor may mediate this effect of berberine.

Objective To explore the effect of " hospital informationized blood glucose management" on perioperative diabetic patients. Methods Three hundred patients with type 2 diabetes mellitus, who underwent selective operations from orthopedics, general surgery, urological surgery, and thoracic surgery were divided into two groups: 150 cases of blood glucose information management group and 150 cases of traditional blood glucose monitoring and management group. The blood glucose on target rate, percent of hypoglycemic events, percent of hyperglycemic events, the blood glucose level on the first postoperative day, the average hospitalization day, perioperative infection rate were evaluated for efficacy. Results The blood glucose on target rate in informationized blood glucose management group was significantly higher than that of the control group [(52.52 ± 18.31)%vs (14.88 ± 8.39)%, P＜0.01]. The frequency of hyperglycemia, the average daily blood glucose, the average blood glucose on fasting, after three meals and at night, the fasting and postprandial blood glucose level on the first postoperative day in informationized blood glucose management group were significantly lower than that of the control group [( 45. 31 ± 18.87)%vs (84.41±8.86)%, (8.59±1.34 vs 12.47±2.37) mmol/L, (7.33±1.41 vs 10.01±1.99)mmol/L, (8.89 ±2.34vs13.61±3.47)mmol/L,(9.47±1.94vs13.46±2.77)mmol/L,(9.40±2.72vs13.28±2.94)mmol/L, (8.28±2.11vs11.31±2.89)mmol/L,(8.29±2.51vs11.58±3.52)mmol/L,(8.25±3.67vs17.65±19.68) mmol/L, all P＜0.01]. In addition, the average hospitalization day of the informationized blood glucose management group was significantly shorter than that of the control group [(16±7 vs 21±15)d, P＜0.05]. The infection rate of the management group and the control group were 41. 2% and 58. 8% respectively. There was no significant difference between two groups (P＞0.05). Conclusion The " hospital informationized blood glucose management" is simple and practical, which may significantly improve the rate of blood glucose control in each period, reduce the average hospitalization day, and decrease perioperative infection tendency.

Objective:To investigate the effects of persistent isolated hypothyroxinemia in the first and second trimester of pregnancy on complications and adverse outcomes of pregnancy.Methods:A retrospective analysis was conducted in 784 pregnant women including 111 cases of persistent isolated hypothyroxinemia in the first and second trimester of pregnancy and 673 pregnant women with normal thyroid function as control group. All women were registered and delivered in the Department of Obstetrics of our hospital from April 2016 to April 2017. The complications and adverse outcomes of pregnancy in the two groups were analyzed.Results:Age, body weight before pregnancy, body mass index(BMI), 1 h plasma glucose and 2 h plasma glucose during oral glucose tolerance test in persistent isolated hypothyroxinemia group were higher than those in control group( P<0.05), with increased incidence of anemia during pregnancy( P<0.05). However, there were no significant differences in the incidences of gestational diabetes mellitus and gestational hypertension between the two groups( P>0.05). No significant statistical differences were found in macrosomia, stillbirth, neonatal malformation, postpartum hemorrhage, acute delivery, premature delivery, fetal intrauterine development delay, and small full-term infants between the two groups( P>0.05). Logistic regression analysis showed that age( OR=1.1, 95% CI 1.0-1.1, P=0.002) and pre-pregnancy body weight( OR=1.0, 95% CI 1.0-1.1, P=0.046) were risk factors for the occurrence of persistent isolated hypothyroxinemia in the first and second trimesters of pregnancy. Persistent isolated hypothyroxinemia in the first and second trimesters was associated with anemia during pregnancy( OR=1.9, 95% CI 1.1-3.2, P=0.024). Conclusions:Pregnant women who are older and heavier before pregnancy should pay more attention to their thyroid function. Pregnant women with persistent isolated hypothyroxinemia in the first and second trimesters should be concerned for anemia.

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.

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.
