文题释义：

人脐带间充质干细胞分化为胰岛样细胞：人脐带间充质干细胞具有多向分化潜能，可分化为骨细胞、脂肪细胞、胰岛细胞等，在相关因子作用下，可使其分化为分泌胰岛素的细胞，称为胰岛样细胞。

葡萄糖耐量：检测胰岛样细胞移植后糖尿病鼠是否可以更好地响应外周血糖浓度变化，释放胰岛素，降低血糖。

摘要

背景：人脐带间充质干细胞诱导的胰岛样细胞移植于1型糖尿病鼠体内，会使血糖降低，糖尿病症状有所改善，但腹腔移植的方式少有报道。

目的：观察不同途径移植人脐带间充质干细胞诱导的胰岛样细胞对于1型糖尿病小鼠的治疗效果。

方法：选采用组织块贴壁法分离培养人脐带间充质干细胞，然后将其定向分化为胰岛样细胞。从15只雄性C57BL/6J小鼠中随机取3只小鼠做正常组，其余12只小鼠腹腔注射链脲佐菌素制备1型糖尿病模型。造模成功9只小鼠随机分为糖尿病组、尾静脉-胰岛样细胞组、腹腔-胰岛样细胞组，每组3只。造模10 d后，正常组和糖尿病组不予处理，尾静脉-胰岛样细胞组经尾静脉注射0.4 mL胰岛样细胞悬液(含5×105个细胞)，腹腔-胰岛样细胞组经腹腔注射0.4 mL胰岛样细胞悬液(含5×105 个细胞)。移植后每周检测2次血糖，移植后28 d进行葡萄糖耐量实验，移植后42 d检测胰岛素水平。

结果与结论：①与糖尿组相比，尾静脉-胰岛样细胞组在移植后第10天开始血糖明显下降，一直维持到31 d，胰岛素水平升高，葡萄糖耐量改善，差异有显著性意义(P < 0.05)；腹腔-胰岛样细胞组血糖、胰岛素水平、葡萄糖耐量未见明显改善；②结果提示，应用人脐带间充质干细胞诱导的胰岛样细胞治疗1型糖尿病鼠，尾静脉注射是一种比较理想的移植方式，腹腔注射的效果不佳。

Abstract

BACKGROUND: Transplanting islet-like cells induced by human umbilical cord mesenchymal stem cells (hUC-MSCs) into type 1 diabetic mice can reduce blood glucose level and improve the symptoms of diabetes mellitus. However, there are few reports on intraperitoneal transplantation.

OBJECTIVE: To study the therapeutic effect of transplantation of islet-like cells induced by hUC-MSCs in different ways for the treatment of type 1 diabetic mice.

METHODS: The hUC-MSCs were isolated and cultured by tissue explants adherent method and differentiated into islet-like cells. The 3 of 15 male C57BL/6J mice were used as normal group, and the remaining mice were taken to prepare a mouse model of type 1 diabetes using intraperitoneal injection of streptozotocin. After successful modeling, nine model mice were randomly divided into diabetes group, tail vein-islet-like cells group, and abdomen-islet-like cells group, with three mice in each group. After 10 days of modeling, the normal group and diabetic group were not treated. The tail vein-islet-like cells group was injected with 5×105 cells/0.4 mL islet-like cells via the tail vein and the abdomen-islet-like cells group was intraperitoneally injected with 5×105 cells/0.4 mL islet-like cells. During the treatment, the blood glucose and insulin levels were measured twice a week; glucose tolerance test was performed at 28 days after cell transplantation; and fasting insulin level was detected at 42 days after cell transplantation.

RESULTS AND CONCLUSION: (1) Compared with the diabetic group, in the tail vein-islet-like cells group, the blood glucose level began to decrease on the 10th day after transplantation and maintained until the 31st day, and the insulin level and glucose tolerance significantly improved (P < 0.05). However, there was no significant improvement in blood glucose level, insulin level and glucose tolerance in the abdomen-islet-like cells group. (2) To conclude, transplantation of hUCMSCs induced islet-like cells for the treatment of type 1 diabetic mice via tail vein is an ideal transplantation method, and the effect of intraperitoneal injection is unsatisfactory.

Abstract

Purpose of Review To synthesize the existing literature regarding the complex interplay between sleep disturbance, obesity, and diabetes. The review emphasizes the three pillars of health being diet, exercise, and sleep, with the notion that if one is ignored, then the other two could suffer.

Recent Findings Sleep deprivation is associated with incident obesity, perhaps mediated by dysregulation in leptin and ghrelin — hormones important in regulation of appetite. Sleep apnea is very common particularly among obese people with type 2 diabetes mellitus. Treatment of sleep apnea has clear symptomatic benefits although its impact on long-term cardiometabolic health is less clear.

Summary Sleep disturbance may be an important modifiable risk for patients at risk of cardiometabolic disease. An assessment of sleep health may be an important component of the comprehensive care of patients with obesity and diabetes mellitus.

ABSTRACT

      Diabetes is the leading cause of chronic kidney disease (CKD), a condition associated with significant morbidity and mortality. As these patients have a high risk of developing cardiovascular disease and end-stage kidney disease, there is a need for early detection and early initiation of appropriate therapeutic interventions that slow disease progression and prevent adverse outcomes. Due to the complex nature of diabetes and CKD management, a holistic, patient-centered, collaborative care approach delivered by a coordinated multidisciplinary team (ideally including a clinical pharmacist as part of a comprehensive medication management program) is needed. In this review, we discuss the barriers to effective care, the current multidisciplinary approach used for CKD prevention and treatment, and the potential ways that the multidisciplinary management of CKD associated with type 2 diabetes mellitus can be refined to improve patient outcomes.

PLAIN LANGUAGE SUMMARY

      People living with type 2 diabetes mellitus are at risk of developing chronic kidney disease. Having chronic kidney disease means that over time the kidneys may not work as well as they should. Some people with chronic kidney disease will eventually need a new kidney (transplant) or will need to use a machine that does the job of their kidneys (dialysis). To slow the rate at which the kidneys get worse, chronic kidney disease needs to be detected and treated early. A multidisciplinary team of healthcare professionals is needed to help people with type 2 diabetes reduce their chances of getting chronic kidney disease, or to prevent their chronic kidney disease from getting worse. Some healthcare teams include a clinical pharmacist who makes sure medicines are given in the correct amount and at the correct time. It is important that the healthcare team members communicate well and include the person with type 2 diabetes and chronic kidney disease and their family members or caregivers (if needed) in the decision-making process to achieve better health results. Barriers stopping people with type 2 diabetes and chronic kidney disease from getting good healthcare include a shortage of nephrologists, not having enough healthcare insurance, limited access to healthcare, and poor understanding about what chronic kidney disease is and how it can be treated. This review article discusses the barriers to better healthcare in chronic kidney disease and how the current healthcare team approach could be changed to improve health results.

Key Summary Points

      Chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) are chronic conditions associated with long-term health, financial, and quality-of-life consequences for patients.

      Barriers to optimized CKD care in people with T2DM include a shortage of specialist clinicians (nephrologists), delays in initiation or appropriate adjustment of evidence-based therapies, inconsistent screening practices, poor health literacy, inadequate healthcare insurance coverage, and limited access to healthcare.

      An effective and well-coordinated multidisciplinary team (MDT), especially one that includes a clinical pharmacist as part of a comprehensive medication management (CMM) program, should proactively address many of these barriers to effective care.

      Implementation of a collaborative care MDT approach (incorporating CMM) for CKD associated with T2DM across the USA is recommended.
