Effect of Renin Angiotensin System Blockade on the Islet Microvessel Density of Diabetic Rats and Its Relationship with Islet Function

To investigate the effects of rennin angiotensin system blockade on the microvessel density in islets of diabetic rats and its relationship with islet function, diabetes model was created by feeding of high-caloric laboratory chow plus intraperitoneal injection of a small dose of streptozotocin （30 mg/kg）. After 8 weeks intervention with perindopril （AE, n=10） or valsartan （AR, n=10）, the islet function of the animals was evaluated by intravenous insulin release test （IVIRT）. The pancreases were immunohistochemically stained to analyze the content of insulin and vascular endothelial growth factor （VEGF） in the islets. The microvessel density （MVD） of islets was detected by counting CD34 positive cells. The hypoxia inducible factor （HIF）-1α mRNA expression in the islets was detected by RT-PCR. Compared with normal control group （NC, n=10）, the area under the curve for insulin from 0 to 30 min （AUCI0-30） of diabetes group （DM, n=8） was decreased by 66.3%; the insulin relative concentration （IRC） of βcell was decreased significantly; the relative content of VEGF was increased obviously [（–4.21±0.13） vs （–4.06±0.29）]; MVD in islets was decreased by 71.4%; the relative expression of HIF-1α mRNA was increased by 1.19 times （all P〈0.01）. Compared with DM group, the AUCI0-30 of AE and AR group was increased by 44.6% and 34.9% respectively; IRC was also increased significantly; the relative content of VEGF was decreased by 21.2% and 21.7% respectively; MVD was increased by 62.5% and 75.0% respectively; the relative expression of HIF-1α was decreased by 27.2% and 29.0% respectively （all P〈0.01 or P〈0.05）. There were no significant differences in the said indexes between group AE and AR. It is concluded that the blockade of RAS may ameliorate islets function of diabetic rats by increasing the MVD in islets.

Objective:To investigate the impact of combining liraglutide with metformin on the enhancement of pancreatic islet function in patients with type 2 diabetes and coronary heart disease.Methods:60 patients with type 2 diabetes and coronary heart disease admitted from February 2022 to August 2023 were selected as research subjects.They were randomly assigned to either control or treatment groups,with 30 patients in each.The control group received metformin alone,while the treatment group received liraglutide in combination with metformin.Various indicators,including blood sugar levels,pancreatic islet function,and cardiac function between the two groups were compared.Results:The results of FPG,2hPG,HbA1c,HOMA-IR,NT-proBNP,and LVEDD in the treatment group were lower than those in the control group,whereas the values of FINS,HOMA-β,E/A,and LVEF in the treatment group were higher than those in the control group(P<0.05).Conclusion:The use of liraglutide in combination with metformin significantly benefits patients with type 2 diabetes and coronary heart disease.It leads to improved pancreatic islet function,better blood sugar control,and enhanced cardiac function.This combination therapy is recommended for clinical adoption.

Relationship between imaging changes of the pancreas and islet beta-cell function

Imaging changes in the pancreas can provide valuable information about the status of islet beta-cell function in different pancreatic diseases,such as diabetes,pancreatitis,pancreatic cancer,fatty pancreas,and insulinoma.While imaging cannot directly measure beta-cell function;it can be used as a marker of disease progression and a tool to guide therapeutic interventions.As imaging techno-logies continue to advance,they will likely play an increasingly important role in diagnosing,monitoring,and managing diabetes.

Influence of heme oxygenase-1 gene transfer on the viability and function of rat islets in in vitro culture

AIM. To investigate the influence of heme oxygenase-1 （HO-1） gene transfer on the viability and function of cultured rat islets in vitro. METHODS： Islets were isolated from the pancreata of Sprague-Dawley rats by intraductal collagenase digestion, and purified by discontinuous Ficoll density gradient centrifugation. Purified rat islets were transfected with adenoviral vectors containing human HO-1 gene （Ad- HO-1） or enhanced green fluorescent protein gene （Ad- EGFP）, and then cultured for seven days. Transfection was confirmed by fluorescence microscopy and Western blot. Islet viability was evaluated by acridine orange/ propidium iodide fluorescent staining. Glucose-stimulated insulin release was detected using insulin radioimmunoassay kits and was used to assess the function of islets. Stimulation index （SI） was calculated by dividing the insulin release upon high glucose stimulation by the insulin release upon low glucose stimulation. RESULTS： After seven days culture, the viability of cultured rat islets decreased significantly （92% ± 6% vs 52% ± 13%, P 〈 0.05）, and glucose-stimulated insulin release also decreased significantly （6.47 ± 0.55 mIU/ L/30IEO vs 4.57 ± 0.40 mIU/L/3OIEO., 14.93 ± 1.17 mIU/L/30IEQ vs 9.63 ± 0.71 mIU/L/30IEQ, P 〈 0.05）. Transfection of rat islets with adenoviral vectors at an 1±10 of 20 was efficient, and did not impair islet function. At 7 d post-transfection, the viability of Ad-HO-1 transfected islets was higher than that of control islets（71% ± 15% vs 52% ± 13%, P 〈 0.05）. There was no significant difference in insulin release upon low glucose stimulation （2.8 mmol/L） among Ad-HO-1 transfected group, Ad-EGFP transfected group, and control group （P 〉 0.05）, while when stimulated by high glucose （16.7 mmol/L） solution, insulin release in Ad-HO-1 transfected group was significantly higher than that in Ad-EGFP transfected group and control group, respectively （12.50 ±2.17 mIU/L/30IEQ vs 8.87 ± 0.65 mIU/L/30IEQ, 12.50 ± 2.17 mIU/L/30IEQ vs 9.63 ± 0.71 mIU/L/30IEQ, P 〈 0.05）. The SI of Ad-HO-1 transfected group was also significantly higher than that of Ad-EGFP transfected group and control group, respectively （2.21 ± 0.02 vs 2.08 ± 0.05; 2.21 ± 0.02 vs 2.11 ± 0.03, P 〈 0.05）. CONCLUSION： The viability and function of rat islets decrease over time in in vitro culture, and heine oxygenase-1 gene transfer could improve the viability and function of cultured rat islets.

Small intestinal submucosa improves islet survival and function during in vitro culture

AIM： To evaluate the recovery and function of isolated rat pancreatic islets during in vitro culture with small intestinal submucosa （SIS）. METHODS： Pancreatic islets were isolated from Wistar rats by standard surgical procurement followed by intraductal collagenase distension, mechanical dissociation and Euroficoll purification. Purified islets were cultured in plates coated with multilayer SIS （SIS-treated group） or without multilayer SIS （standard cultured group） for 7 and 14 d in standard islet culture media of RPMI 1640. After isolation and culture, islets from both experimental groups were stained with dithizone and counted. Recovery of islets was determined by the ratio of counts after the culture to the yield of islets immediately following islet isolation. Viability of islets after the culture was assessed by the glucose challenge best with low （2.7 mmol/L） and high glucose （16.7 mmol/L） solution supplemented with 50 mmol/L 3-isobutyl-1- methylxanthine （IBMX） solution. Apoptosis of islet cells after the culture was measured by relative quantification of histone-complexed DNA fragments using ELISA. RESULTS： After 7 or 14 d of in vitro tissue culture, the recovery of islets in SIS-treated group was significantly higher than that cultured in plates without SIS coating. The recovery of islets in SIS-treated group was about twice more than that of in the control group. In SIS treated group, there was no significant difference in the recovery of islets between short- and long-term periods of culture （95.8±1.0% vs 90.8±1.5%, P〉0.05）. When incubated with high glucose （16.7 mmol/L） solution, insulin secretion in SIS-treated group showed a higher increase than that in control group after 14 d of culture （20.7±1.1 mU/L vs 11.8±1.1 mU/L, P〈0.05）. When islets were placed in high glucose solution containing IBMX, stimulated insulin secretion was higher in SlS-treated group than in control group. Calculated stimulation index of SlS-treated group was about 23 times of control group. In addition, the stimulation index of SlS-treated group remained constant regardless of short- and long- term periods of culture （9.5±0.2 vs 10.2±1.2, P〉0.05）. Much less apoptosis of islet cells occurred in SlS-treated group than in control group after the culture. CONCLUSION： Co-culture of isolated rat islets with native sheet-like SIS might build an extracellular matrix for islets and provide possible biotrophic and growth factors that promote the recovery and subsequent function of islets.

EFFECTS OF GLUCAGON ON ISLET β CELL FUNCTION IN PATIENTS WITH DIABETES MELLITUS

Objective To evaluate islet β cell response to intravenous glucagon （ a non-glucose secretagogue） stimulation in diabetes mellitus. Methods Nineteen patients with type 1 diabetes （T1 D） and 131 patients with type 2 diabetes （T2D） were recruited in this study. T2D patients were divided into two groups according to therapy： 36 cases treated with insulin and 95 cases treated with diet or oral therapy. The serum C-peptide levels were determined at fasting and six minutes after intra- venous injection of 1 mg of ghicagon. Results Both fasting and 6-minute post-ghicagon-stimulated C-peptide levels in T1D patients were significantly lower than those of T2D patients （0. 76±0. 36 ng/mL vs. 1.81±0. 78 ng/mL, P 〈 0.05 ; 0.88±0.42 ng/mL vs. 3.68±0. 98 ng/mL, P 〈 0. 05 ）. In T1D patients, the C-peptide level after injection of ghicagon was similar to the fasting level. In T2D, patients treated with diet or oral drug had a significantly greater fasting and stimulated C-peptide level than those patients received insulin therapy （2.45±0. 93 ng/mL vs. 1.61±0. 68 ng/mL, P 〈 0.05 ; 5.26±1.24 ng/mL vs. 2.15±0.76 ng/mL, P 〈 0.05 ）. The serum C-peptide level after ghicagon stimulation was positively correlated with C-peptide levels at fasting in all three groups （ r = 0.76, P 〈 0.05 ）. Conclusions The 6-minute ghicagon test is valuable in assessing the function of islet β cell in patients with diabetes mellitus. It is helpful for diagnosis and treatment of diabetes mellitus.

Relationship between Free Thyroxine and Islet Beta-cell Function in Euthyroid Subjects

Thyroid hormones have a specific effect on glucose-induced insulin secretion from the pancreas.We aimed to investigate the association between euthyroid hormones and islet betacell function in general population and non-treated type 2 diabetes mellitus(T2DM)patients.A total of 5089 euthyroid participants(including 4601 general population and 488 non-treated T2DM patients)were identified from a cross-sectional survey on the prevalence of metabolic diseases and risk factors in East China from February 2014 to June 2016.Anthropometric indices,biochemical parameters,and thyroid hormones were measured.Compared with general population,non-treated T2DM patients exhibited higher total thyroxine(TT4)and free thyroxine(FT4)levels but lower ratio of free triiodothyronine(T3):T4(P<0.01).HOMA-βhad prominently negative correlation with FT4 and positive relationship with free T3:T4 in both groups even after adjusting for age,body mass index(BMI)and smoking.When analyzed by quartiles of FT4 or free T3:T4,there were significantly decreased trend of HOMA-β going with the higher FT4 and lower free T3:T4 in both groups.Linear regression analysis showed that FT4 but not FT3 and free T3:T4 was negatively associated with HOMA-β no matter in general population or T2DM patients,which was independent of age,BMI,smoking,hypertension and lipid profiles.FT4 is independently and negatively associated with islet beta-cell function in euthyroid subjects.Thyroid hormone even in reference range could play an important role in the function of pancreatic islets.

Islet cell transplantation as a cure for insulin dependent diabetes: current improvements in preserving islet cell mass and function

OBJECTIVE: To review the current progress of islet cell transplantation in patients with insulin-dependent diabetes, emphasizing on the difficulties with recovering and preserving islet cell mass and function, 30% of which is lost during the peri-transplantation period. RESULTS: The islet-cell isolation technique is perfected, but improvements are still progressing in two major directions: preservation of islet cells and tolerance induction. Optimum islet cell viability and function depends on appropriate revascularization of the islet graft and blockade of thrombus formation as well as cytokine and free radical release. Conditioning the islet cells in-vitro prior to transplantation to either upregulate VEGF expression or downregulate NF-kappa B transcription factor has proven to improve revascularization and to prevent islet cell apoptosis and cytokine-mediated damage. Tolerance induction is currently being best achieved by selecting and combining immunosuppressive agents such as monoclonal antibodies which target the major signaling molecules during immune activation, but which are least toxic to islet cells. CONCLUSIONS: Patients with insulin-dependent diabetes will greatly benefit from current developments in effective approaches to protect islets during the peritransplant period. Emerging interest in stem cell biology and differentiation may provide the ultimate solution to the problem of organ scarcity and islet cell protection from the peritransplant induced damage.

Characterization of Islets from Chronic Calcific Pancreatitis Patients of Tropical Region with Distinct Phenotype

Background and Objective: Islet autotransplantation is performed to preserve endocrine function in patients undergoing pancreatic resections for painful chronic pancreatitis. We characterized islets isolated from chronic pancreatitis patients (CP) of tropical region. Patients and Methods: Pancreatic tissues were obtained from CP patients with and without diabetes undergoing pancreatic resections (n = 35) and brain-dead multi organ donors (n = 6;considered as controls). Islets isolated were assessed for yield, purity, viability and in vitro islet function (Glucose stimulated insulin release, GSIR) as per standard protocols. Results: Islets from CP patients without diabetes were similar to controls in yield (control 4120 - 6100 IE/g, CP 3550 - 5660 IE/g), purity (control 78% ± 12%, CP 70% ± 8.2%) and viability (control 85% ± 8%, CP 81% ± 10%) and islets from CP patients with diabetes showed decreases in yield (3002 - 2300 IE/g), purity (61% ± 16%) and viability (62% ± 21%). Islets measuring 50 - 200 μ were similar in abundance in controls (94.74% ± 3.2%) and CP patients with and without diabetes, 86.31% ± 4.9%, 91.03% ± 3.8%. GSIR of islets from CP patients and controls were similar at 5.5 mM glucose (2.8 - 3.1 μU/ml). However, GSIR at 16.5 mM glucose was decreased in CP patients (control 18.5 ± 0.6, CP without diabetes 11.8 ± 0.3, CP with diabetes 4.3 ± 0.3 μU/ml). Conclusion: Our results demonstrate suitability of islets isolated from CP patients of tropical region for autotransplantation.

Six-year follow-up of pancreatic β cell function in adults with latent autoimmune diabetes

AIM: To investigate the characteristics of the progression of islet β cell function in Chinese latent autoimmune diabetes in adult (LADA) patients with glutamic acid decarboxylase antibody (GAD-Ab) positivity, and to explore the prognostic factors for β cell function. METHODS: Forty-five LADA patients with GAD-Ab positivity screened from phenotypic type 2 diabetic (T2DM) patients and 45 T2DM patients without GAD-Ab matched as controls were followed-up every 6 mo. Sixteen patients in LADA1 and T2DM1 groups respectively have been followed-up for 6 years, while 29 patients in LADA2 and T2DM2 groups respectively for only 1.5 years. GAD-Ab was determined by radioligand assay, and C-peptides (CP) by radioimmune assay.RESULTS: The percentage of patients whose fasting CP(FCP) decreased more than 50% compared with thebaseline reached to 25.0% at 1.5th year in LADA1 group, and FCP level decreased (395.8±71.5 vs 572.8±72.3 pmol/L, P＜0.05) at 2.5th year and continuously went down to the end of follow-up. No significant changes of the above parameters were found in T2DM1 group. The average decreased percentages of FCP per year in LADA and T2DM patients were 15.8% (4.0-91.0%) and 5.2% (-3.5 to 35.5%, P= 0.000) respectively. The index of GAD-Ab was negatively correlated with the FCP in LADA patients (rs= -0.483, P = 0.000). The decreased percentage of FCP per year in LADA patients were correlated with GAD-Ab index, body mass index (BMI) and age at onset (rs = 0.408, -0.301 and -0.523 respectively, P＜0.05). Moreover, GAD-Ab wasthe only risk factor for predicting βcell failure in LADA patients (B = 1.455, EXP (B) = 4.283, P = 0.023). CONCLUSION: The decreasing rate of islet β cell function in LADA, being highly heterogeneous, is three times that of T2DM patients. The titer of GAD-Ab is an important predictor for the progression of islet β cell function, and age at onset and BMI could also act as the predictors.

目的探究参黄降糖胶囊联合穴位贴敷对2型糖尿病病人胰岛功能及脂联素水平的影响。方法通过随机数字表法将2020年2月至2022年2月河北省沧州中西医结合医院接收的200例气阴两虚型2型糖尿病病人分为对照组(n=100,强化生活方式干预+二甲双胍肠溶片)和研究组(n=100,强化生活方式干预+二甲双胍肠溶片+参黄降糖胶囊和穴位贴敷)。比较两组病人临床治疗效果、胰岛功能指标、脂联素水平、中医证候积分、脂代谢水平。结果研究组总有效率(90.00%,90/100)高于对照组(79.00%,79/100)(P<0.05)。治疗后,研究组和对照组病人胰岛素抵抗指数(HOMA-IR)较治疗前降低(P<0.05),研究组低于对照组(2.51±0.48比2.99±0.59,P<0.05);空腹胰岛素(FINS)、HOMA-β较治疗前升高(P<0.05),研究组高于对照组[(11.92±1.46)mIU/L比(8.47±1.88)mIU/L,124.86±35.96比69.55±21.35;P<0.05]。治疗后,研究组和对照组病人脂联素水平较治疗前升高(P<0.05),研究组高于对照组[(19.04±5.37)mg/L比(16.02±5.58)mg/L,P<0.05]。治疗后,研究组和对照组病人中医证候积分较治疗前降低(P<0.05),研究组低于对照组(P<0.05)。治疗后,研究组和对照组病人总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)较治疗前降低(P<0.05),研究组低于对照组(P<0.05)。结论参黄降糖胶囊联合穴位贴敷对2型糖尿病病人临床治疗效果显著,可改善胰岛功能、脂联素水平和脂代谢水平,减轻临床症状。

2型糖尿病湿热困脾证合并血脂紊乱胰岛功能变化及其影响因素分析

目的探讨2型糖尿病湿热困脾证合并血脂紊乱患者胰岛功能变化及其影响因素。方法选择2020年1月—2020年12月医院收治的2型糖尿病湿热困脾证患者100例,根据美国ATPIII评估标准将其分为血脂紊乱组62例与血脂正常组38例。比较各组SF-36积分、胰岛素分泌功能(Homeostasis model assessment-β,HOMA-β)、胰岛素抵抗水平(Homeostasis model assessment-IR,HOMA-IR)、胰岛素敏感指数(Insulin sensitivity index,ISI)、空腹C肽和空腹胰岛素。应用单因素和多因素分析法研究血脂异常的相关因素。结果高甘油三酯组与混合型高脂组空腹胰岛素水平显著高于高胆固醇组与血脂正常组,差异有统计学意义(P<0.05)。高甘油三酯组空腹C肽水平显著高于高胆固醇组,差异有统计学意义(P<0.05)。混合型高脂组与高甘油三酯组的ISI水平低于高胆固醇组(P<0.05)。高甘油三酯组HOMA-β水平明显高于高胆固醇组与血脂正常组,差异有统计学意义(P<0.05)。高甘油三酯组及混合型高脂组HOMA-IR水平显著高于高胆固醇组,差异有统计学意义(P<0.05)。两组患者在躯体疼痛、整体健康、活力、社会功能和精神健康维度方面比较,差异有统计学意义(P<0.01)。多因素Logistic分析显示,喜食油腻、吸烟史、腰围和空腹胰岛素是2型糖尿病湿热困脾证患者血脂异常的危险因素,有氧运动是2型糖尿病湿热困脾证患者血脂异常的保护因素(P<0.05)。结论不同血脂紊乱类型对胰岛功能的影响并不相同,应针对相关因素积极预防,降低胰岛分泌负担,促使胰岛功能恢复。

西藏门巴族人群胰岛细胞功能、脂质代谢、炎症反应与中医体质的相关性研究

目的探讨西藏门巴族人群胰岛细胞功能、脂质代谢和炎症反应与中医体质的相关性。方法选取2023年1月—2023年6月墨脱村、亚东村、朗杰岗村、巴日村、德吉村、玛迪村6个门巴族乡的门巴族人群进行调查,共计237例。分析人群中医体质分布情况,同时比较前三位中医体质人群的胰岛细胞功能、脂质代谢和炎症因子水平。结果中医体质类型中以痰湿质、湿热质和气虚质为主,分别占32.07%、26.16%和18.57%。痰湿质组、湿热质组和气虚质组性别、年龄、体质量指数比较,差异均无统计学意义(P>0.05)。湿热质组空腹血糖和胰岛素抵抗指数分别为(4.98±0.83)mmol/L和(1.75±0.32),均低于痰湿质组和气虚质组(P<0.05),湿热质组胰岛β细胞功能指数为(94.45±9.11),均高于痰湿质和气虚质组(P<0.05);湿热质组总胆固醇和甘油三酯分别为(3.98±0.99)mmol/L和(1.02±0.29)mmol/L,均低于痰湿质组和气虚质组(P<0.05),湿热质组高密度脂蛋白胆固醇为(1.26±0.20)mmol/L,均高于痰湿质组和气虚质组(P<0.05)。痰湿质、湿热质和气虚质组血清白细胞介素-6、超敏c反应蛋白、肿瘤坏死因子-α比较,差异均无统计学意义(P>0.05)。结论西藏门巴族人群中医体质以痰湿质、湿热质和气虚质为主,其中湿热质人群胰岛细胞功能、脂质代谢优于痰湿质和气虚质人群,炎症因子比较无差异。
