ABSTRACT
Objective:To investigate the effect of high glucose on the release of interleukin (IL)-1β and IL-18 in placental trophoblast by activating NLRP3 inflammasome.Methods:Gestational diabetes mellitus(GDM) placentas and control placentas were collected and the expression levels of NLRP3 and Caspase-1 were determined. Human placental trophoblast HTR-8/SVneo were cultured and divided into control group(5.5 mmol/L glucose), high glucose group(25 mmol/L glucose), DMSO+ high glucose group, and Ac-YVAD-cmk(NLRP3 inflammasome inhibitor)+ high glucose group. The expression levels of NLRP3 and Caspase-1 in cells as well as the contents of IL-1β and IL-18 in the medium were determined.Results:The expression levels of NLRP3 and Caspase-1 in GDM placenta were higher than those in control placenta( P<0.05) and positively correlated with homeostasis model assessment of insulin resistant index(HOMA-IR) and fasting insulin. The expression levels of NLRP3 and Caspase-1 in HTR-8/SVneo cells and the secretion levels of IL-1β and IL-18 in high glucose group were higher than those in control group( P<0.05). Ac-YVAD-cmk significantly suppressed high glucose-stimulated IL-1β and IL-18 secretion( P<0.05). Conclusion:High glucose promotes the release of IL-1β and IL-18 from placental trophoblast via activating NLRP3 inflammasome.
ABSTRACT
Objective:To assess the implementation of injection-related risk management based on WeChat platform for type 2 diabetic patients with the insulin self-injection.Methods:A total of 124 diabetic patients, who would receive insulin therapy by self-injection at home after discharge from the PLA 903 hospital during April 2017 to July 2018, were divided into the control group( n=62)and the study group( n=62). All patients were given routine education on insulin injection during the hospitalization,while the study group( n=62)received additional video and text education based on WeChat platform after discharge.

Conclusion:The risk management based on WeChat platform can improve insulin self-injection skill and the ability of dealing with hypoglycemia,also promote effective blood glucose control for diabetes patients.
ABSTRACT
Objective:To compare the clinical outcomes of one and two blastocysts in the freeze-thaw transplantation cycle.Methods:Totally 3 675 cycles of frozen thawed blastocyst transplantation in Reproductive Medical Center of the Second Nanning People′s Hospital from January 2012 to December 2016 were analyzed retrospectively. According to the quantity and quality of transferred blastocysts, all the patient were divided into two groups: (1) one embryo group, including the single excellent group (one high quality blastocyst) and the single non excellent group (one non high quality blastocyst); (2) two embryo groups, including the double excellent group (two high quality blastocysts), the one excellent and one non excellent group (one high quality blastocyst+one non high quality blastocyst), and the two non excellent group (two non high quality blastocysts were transplanted). Then the patients were divided into subgroups according to their ages: less than 35 years old, 35-40 years old and over 40 years old. On this basis, the implantation rate, clinical pregnancy rate, multiple birth rate and live birth rate were compared.Results:(1) The implantation rate, clinical pregnancy rate, multiple birth rate, preterm birth rate and live birth rate were all significantly increased, while the abortion rate was significantly reduced in the double blastocyst group (all P<0.05). (2) In the group of<35 years old, the rates of multiple birth and preterm birth in the double blastocyst group were significantly higher than those in the single optimal group ( P<0.01). (3) In the 35-40 years old group, the clinical pregnancy rate, multiple birth rate and live birth rate of the double excellent group were significantly higher than those of the single excellent group ( P<0.01); while the clinical pregnancy rate and live birth rate of the one excellent and one non excellent group and the double non excellent group were not significantly different from those of the single excellent group ( P>0.05), but the multiple birth rate and preterm birth rate were significantly increased ( P<0.01). The clinical pregnancy rate, live birth rate and multiple birth rate of double non optimal group were significantly higher than those of single non optimal group ( P<0.01). (4) In the group>40 years old, there were no significant differences in clinical pregnancy rate and live birth rate between the two groups ( P>0.05). There were no significant differences in implantation rate, clinical pregnancy rate and live birth rate between double non optimal group and single non optimal group ( P>0.05). Conclusion:No matter the age of the patients, if the couple have high quality blastocysts, we should give priority to single high quality blastocyst transplantation; even if they have no high quality blastocysts, we should also consider single blastocyst transplantation, in order to reduce the risk of multiple pregnancy and improve the cumulative live birth rate, so as to improve the pregnancy outcome.
ABSTRACT

ABSTRACT
The clinical data of 96 patients with type 2 diabetes mellitus (T2DM) treated in Department of endocrinology of our hospital from January 2016 to December 2017 were retrospectively analyzed. All patients had been treated with metformin ≥1 000 mg combined with sulfonylureas for>12 weeks and their glycosylated hemoglobin (HbA1c) was>7.5%. On the basis of the original scheme, 57 patients received oral sitagliptin (100 mg q.d, sitagliptin group) and 39 patients received insulin glargine injection (insulin group) for 26 weeks. The blood lipid, liver and kidney function were examined before and after treatment. The abdominal visceral fat area (VFA) was measured by CT scan. Results showed that the fasting plasma glucose (FPG) , 2-hour postprandial blood glucose (2 hPG) and HbA1c were significantly lower than baseline levels in both groups(P<0.05). The decrease of VFA in sitagliptin and insulin groups was by 9.6 (1.4,19.6)cm2 and by 8.3(-2.2,26.8) cm2, respectively; there was significant difference in variation of VFA before and after treatment between the two groups (P<0.05). There was no significant difference in blood pressure, liver function (ALT, AST) and estimated glomerular filtration rate (eGFR) before and after treatment in the sitagliptin group (P>0.05). Additional sitagliptin administration can effectively and safely reduce HbA1c and decrease the abdominal visceral fat content in T2DM patients who failed to metformin and sulfonylureas combined therapy.
ABSTRACT
Objective To study the effect of hydrogen sulfide on the production of soluble fms-like tyrosine kinase 1 (sFlt-1) through a distintegrin and metalloproteinase 17 (ADAM17) in adipocytes. Methods 3T3-L1 cells were cultured and induced to differentiate into adipocytes, then treated with different doses of sodium hydrogen sulfide (NaHS), L-cysteine or transfected with cystathionine-γ-lyase ( CSE) siRNA, ADAM17 siRNA or treated with ADAM17 inhibitor, monoclonal antibody. 24 hours after treatment, the expression of ADAM17, CSE, and the production of sFlt-1 were determined. Results After the treatment of 10, 25, 50 nmol/L NaHS or 0. 5, 1. 0, 2. 0 μmol/L L-cysteine, the expression of ADAM17 and the production of sFlt-1 in adipocytes were significantly decreased, the higher dose of L-cysteine and sFlt-1, the lower expression of ADAM17 and the production of sFlt-1; the effect of 2.0 μmol/L L-cysteine decreasing the expression of ADAM17 and the production of sFlt-1 were reversed by transfection of CSE siRNA; after the transfection of ADAM17 siRNA and treatment of ADAM17 inhibitor or monoclonal antibody, the production of sFlt-1 in adipocytes were significantly decreased. Conclusion Hydrogen sulfide can reduce the production of sFlt-1 in adipocytes by downregulating the expression of ADAM17.
ABSTRACT
Objective To investigate the effect of hydrogen sulfide′s donor NaHS on the secretion of interleukin (IL)-1β and IL-18 in adipocytes and its mechanism.Methods 3T3-L1 cells were induced to differentiate into adipocytes and incubated with various concentrations of NaHS or 10 μg/ml caspase-1 inhibitor Ac-YVAD-CMK for 24 hours.The expressions of NLRP3(NLR family, pyrin domain containing 3), ASC(apoptosis associated speck-like protein containing CARD domain), caspase-1, IL-1β, and IL-18 in adipocytes, as well as the content of IL-1 and IL-18 in culture medium were determined.Results 10, 25, and 50 nmol/L NaHS significantly decreased NLRP3, ASC, and cleaved-caspase-1 protein expressions in adipocytes, as well as IL-1β and IL-18 contents in culture medium in a dose-dependent manner.The mature-IL-1β/pro-IL-1β, mature-IL-18/pro-IL-18 ratios in adipocytes and IL-1β and IL-18 contents in culture medium were also reduced by 10μg/ml Ac-YVAD-CMK.Conclusion Donor of hydrogen sulfide NaHS inhibits the maturation and secretion of IL-1β and IL-18 in adipocytes through downregulating the expression of NLRP3 inflammasome.

ABSTRACT
Objective To investigate the association of serum visfatin and free fatty acid (FFA) with insulin resistance in type 2 diabetes mellitus (T2DM).Methods One hundred and nineteen patients with T2DM and 65 health subjects with normal glucose tolerance (NGT) were enrolled in the study.TheT2DM patients were further classified as insulin resistant (HOMA-IR ＞ 2.8 mU/L,T2DM-IR group,n =61) and non-insulin resistant (HOMA-IR≤2.8 mU/L,T2DM-NIR group,n =58).Serum visfatin,free fatty acid and related clinical variables were measured,and HOMA-IR was calculated.Results The serum levels of visfatin and FFA in T2DM patients were significantly higher than those in healthy controls [(4.7 ±2.5) vs.(1.7±0.9) ng/L,t=-11.831,P＜0.01; (1.65±0.69) vs.(0.61 ±0.21) mmol/L,t=-9.239,P ＜0.01].The serum levels of visfatin and FFA in T2DM-IR group were significantly higher than those in T2DM-NIR group [(6.3±2.3) vs.(3.0±1.4) ng/L,P＜0.01; (2.16±0.45) vs.(1.12± 0.46) mmol/L,P ＜0.01].Multiple regression analysis showed that FFA,fasting insulin level and waist/ hip ratio (WHR) were independent risk factors of serum visfatin level (r =0.564,0.267 and 0.188 respectively,all P ＜ 0.05).Conclusion Serum levels of visfatin and FFA are increased in T2DM,and they are closely associated with insulin resistance.
ABSTRACT
Objective To investigate the association of serum levels of soluble intercellular cell adhesion molecule-1 (sICAM-1),soluble vascular cell adhesion molecule-1 (sVCAM-1) and high sensitivity C-reactive protein (hs-CRP) with peripheral vascular disease of lower limbs in patients with type 2 diabetes mellitus (T2DM).Methods One hundred and thirty T2DM patients admitted from October 2011 to October 2012,and 30 age/sex-matched healthy subjects were enrolled in the study.The serum levels of sICAM-1,sVCAM-1,hs-CRP and other clinical parameters were measured; the peripheral blood vessels of lower limbs were examined with color Doppler ultrasonography.Based on the extent of angiopathy of lower limbs T2DM patients were classified as normal vascular group (n =26),mild angiopathy group (n =45),moderate/severe angiopathy group (n =59).Results The serum levels of sICAM-1 and sVCAM-1 in moderate/ severe angiopathy group of T2DM patients were higher than those in mild angiopathy group,normal vascular group and healthy controls (t:4.15-8.93,all P ＜0.05) ; the serum levels of hs-CRP in moderate/severe angiopathy group were higher than those in mild angiopathy group,normal vascular group and healthy controls (t:2.18-4.27,all P ＜ 0.05).The serum sICAM-1 level was positively correlated with total cholesterol (TC),low density lipoprotein cholesterol (LDL-C) and sVCAM-1.The serum sVCAM-1 level was positively correlated with course of disease,systolic blood pressure and CRP.Conclusions Serum levels of sICAM-1,sVCAM-1 and hs-CRP are correlated with the extent of angiopathy of lower limbs in T2DM patients,and the elevated sICAM-1 ; sVCAM-1 and hs-CRP levels are also associated with hyper blood pressure,dislipidemia and chronic inflammation.
ABSTRACT
Seventy patients with type 2 diabetes (T2DM),23 subjects with impaired glucose tolerance (IGT) and 35 individuals with normal glucose tolerance (NGT) were recruited in the study.Fasting free fatty acids (fFFA) and postprandial free fatty acids (2 hFFA) after oral glucose tolerance test (OGTT) were measured; homeostasis model assessment of insulin resistance (HOMA-IR),area under the curve of free fatty acids (AUCFFA) were calculated.The carotid artery intima-media thickness (IMT) was assessed by color ultrasonography.HOMA-IR,fFFA,2 hFFA,AUCFFA and IMT in T2DM group were 3.3 ±3.2,(0.55 ± 0.20) mmol/L,(0.28 ±0.18)mmol/L,(0.83 ±0.34)mmol · L-1 · h-1 and (0.12±0.05) cm,which were significantly higher than those in NGT group,respectively [1.9 ± 1.3,(0.41 ±0.15) mmol/L,(0.12 ± 0.10) mmol/L,(0.53 ± 0.20) mmol · L-1 · h 1 and (0.09 ± 0.03) cm,all P ＜0.05].Both HOMA-IR and IMT were positively correlated with fFFA,2 hFFA and AUCFFA (all P ＜ 0.05).The results indicate that the levels of fasting and postprantial free fatty acid were related with insulin resistance and atherosclerosis of carotid artery.

ABSTRACT
Serum matrix metalloproteinase-9 (MMP-9), hypersensitive C-reactive protein (hsCRP) and other clinical parameters were measured in patients with types 2 diabetes mellitu (with or without angiopathy of lower limbs). The serum levels of MMP-9 and hsCRP were higher in type 2 diabetic patients and those with angiopathy by Doppler ultrasonography than those in normal controls. The change of serum MMP-9 was positively correlated with the level of hsCRP. The extent of angiopathy was correlated positively with both hsCRP and MMP-9.
