Myocardial disorders such as acute myocardial infarction endanger millions of people and cause a substantial number of deaths each year; 1 of every 6 deaths all over the world. After an acute myocardial infarction (MI), the heart has a limited capacity of self-renewal undergoing remodelling with resulting left ventricular dysfunction (LVD).1,2 Despite the improvement in several pharmacological, interventional and surgical therapeutic measures, the prognosis for heart failure patients remains very poor. Although an early wave of clinical trials has generated marginal success; medical researchers and regulators face new issues and uncertainties involving longterm safety and efficacy. Put together these observations; account for the continued search for new optional treatments. Among many alternatives, cellular therapy has gained a growing interest as the new field exploiting cells to generate biological substitute, improve tissue function and thereby restoring the damaged tissue with high proliferability and differentiability.3,4 It is also being focused as a potential alternative to complicated tissue or organ transplantation because several factors have been cited as causes for disparities in organ donation and its successful transplantation such as lack of education, religious beliefs, distrust of the health care system, lack of communication between healthcare providers and minority patients and desire of minority members to donate their organs only to members of their same ethnic classification.
急性心肌梗死等心肌疾病危及数百万人,每年造成大量死亡;全世界每6例死亡中就有1例。急性心肌梗死(MI)后,心脏自我更新能力有限,正在进行重构,导致左心室功能障碍(LVD)。1,2尽管一些药物、介入和手术治疗措施有所改善,但心力衰竭患者的预后仍然很差。尽管早期的一波临床试验取得了微小的成功;医学研究人员和监管机构面临着涉及长期安全性和有效性的新问题和不确定性。把这些观察结果放在一起;考虑到继续寻找新的可选治疗方法。在众多替代疗法中,细胞疗法作为利用细胞产生生物替代品,改善组织功能,从而以高增殖性和可分化性恢复受损组织的新领域,受到越来越多的关注。它也被认为是复杂组织或器官移植的潜在替代品,因为有几个因素被认为是器官捐赠及其成功移植的差异的原因,如缺乏教育,宗教信仰,对医疗保健系统的不信任,医疗保健提供者与少数民族患者之间缺乏沟通,以及少数民族成员希望只将其器官捐赠给相同种族分类的成员。

Multipotent mesenchymal stromal cells derived from human adipose tissue were used for transplantation. Cellular suspension from adipose tissue was diluted with Dulbecco’s Phosphate Buffered Saline (DPBS), (“Gibco”) 1:2, layered on a density gradient of Histopaque 1.077 (“Sigma”) and centrifuged for 30 minutes at 600g. Then, interfacial mononuclear rings were collected into centrifugal test tubes (“Corning”), washed by centrifugation in excess DPBS. The resulting cell sediment was resuspended in a culture medium and placed in culture test tubes (“Corning”, 25cm2) and transferred to a 37°C constant incubator with 5% carbon dioxide gas.

Prevention and treatment of cerebral palsy caused by intrapartum damage with novel hypoxia index 应用新型缺氧指数预防和治疗产时损伤所致脑瘫
Pub Date : 2018-10-05 DOI: 10.15406/JSRT.2018.04.00122

Cerebral palsy is a big problem in fetal monitoring. Novel hypoxia index=the sum of all fetal heart rate deceleration durations (min) in fetal monitoring, which is divided by the lowest fetal heart rate (bpm), and multiplied by 100. The hypoxia index of all 6 cerebral palsy cases was 25 or more, while the index of all 16 normal non cerebral palsy cases was 24 or less. Thus, cerebral palsy is prevented, if hyoxia index is 24 or less in the birth, and the newborn babies whose hypoxia index was 25 or more can be treated by early cerebral palsy therapy in neonatal stage. As the hypoxia index is adopted to all of deceleration patterns and continuous bradycardia because its calculation equation did not include lag-time, traditional but subjective early, late and variable deceleration pattern classification will change to numeric hypoxia index in fetal monitoring.
脑瘫是胎儿监测中的一大难题。新型缺氧指数=胎儿监测中所有胎心率减速持续时间(min)之和,除以最低胎心率(bpm),再乘以100。6例脑瘫患者缺氧指数均在25及以上,16例正常非脑瘫患者缺氧指数均在24及以下。因此,如果出生时缺氧指数小于等于24,新生儿缺氧指数大于等于25的新生儿可在新生儿期进行早期脑瘫治疗,可预防脑瘫。由于缺氧指数的计算公式不包含时滞,因此对所有减速模式和持续性心动过缓均采用缺氧指数,传统的主观早、晚、可变的减速模式分类将在胎儿监护中转变为数字缺氧指数。

Normal adult stem cells are characterized by their ability to selfrenew, as well as their ability to differentiate into various mature cell types. Cancer stem cells were first recognized by Bonnet et al, who showed a sub-portion of acute myelogenous leukemia (AML) stem cells could be identified and separated from AML cells in patients. This subset of AML cells were the only cells capable of transferring AML from the human patients to studied mice.1 The hypothesis of the existence of cancer stem cells gained more attention around 2001 when Reya et al pushed the notion that cancer stems cells are composed of a subset fraction of tumor cells that have the ability to maintain the tumor through self-renewal, conferring drug resistance, and inducing tumor relapse.2 These cancer stem cells have similar physiologic properties to normal adult stem cells, like self-renewal and differentiation. Normal stem cells had been shown to be resistant to cytotoxic agents compared to mature cell types, which is explained by anti-apoptotic mechanisms,3 quiescence,4 and high expression levels of ATP-binding cassette (ABC) transporters.5 Thus, the existence of cancer stem cells explains the reason why many treatments for metastatic tumors ultimately fail. Current treatments like chemotherapy and radiation can shrink, but not cure metastatic tumors. Frequently, these treatments do indeed target the bulk of tumor cells in the human body, but often, the drug therapy is unable to kill the cancer stem cells (due to inherited and/or acquired resistance), and thus the tumor can easily grow back. In recent years, cancer stem cells have been identified and isolated by characteristics of normal stem cells, like using tissue specific CD markers (The cluster of differentiation) and ABC transporter proteins.6 Research about targeted therapy in regard to these cancer stem cells has come in full swing over the past decade.
正常成体干细胞的特点是具有自我更新的能力,以及分化成各种成熟细胞类型的能力。肿瘤干细胞最早是由Bonnet等人发现的,他们发现急性髓性白血病(acute myelelogenous leukemia, AML)干细胞的一个亚部分可以从患者的AML细胞中被识别和分离出来。AML细胞的这个亚群是唯一能够将AML从人类患者转移到研究小鼠的细胞2001年前后,Reya等人提出癌症干细胞是由肿瘤细胞亚群组成的,这些肿瘤细胞具有通过自我更新、赋予耐药性和诱导肿瘤复发的能力,癌症干细胞的存在假说得到了更多的关注这些癌症干细胞具有与正常成体干细胞相似的生理特性,如自我更新和分化。与成熟细胞类型相比,正常干细胞已被证明对细胞毒性药物具有抗性,这可以通过抗凋亡机制,3静止,4和atp结合盒(ABC)转运体的高表达水平来解释因此,癌症干细胞的存在解释了许多转移性肿瘤治疗最终失败的原因。目前的治疗方法,如化疗和放疗,可以缩小,但不能治愈转移性肿瘤。通常,这些治疗确实针对人体中的大部分肿瘤细胞,但通常,药物治疗无法杀死癌症干细胞(由于遗传和/或获得性抵抗),因此肿瘤很容易生长回来。近年来,利用组织特异性CD标记(The cluster of differentiation)和ABC转运蛋白等正常干细胞的特点,对肿瘤干细胞进行了鉴定和分离在过去的十年里,针对这些癌症干细胞的靶向治疗研究正如火如荼地进行着。

Mitochondrial Ca2+ levels lower down rate of metabolic diseases and cardiomyopathies 线粒体Ca2+水平降低代谢性疾病和心肌病的发病率

Mitochondrial is an important cell organelle that generates ATP that is used as sole energy molecule for all physiological and metabolic activities. It supplies cellular energy and assist in signaling, cell metabolism, cellular differentiation, cell survival and other cell-specific functions. Calcium uptake takes place through mitochondrial outer membrane by voltage-dependent anion channels. After formation of electrochemical gradient and equilibrium on both sides’ mitochondrial functions become normal. It is maintained during oxidative phosphorylation. Thus buffering of cytosolic Ca2+ levels regulate mitochondrial effector functions. Ca2+ transported into mitochondria regulates its metabolism and causes transient depolarisation of mitochondrial membrane. Imbalance in Ca2+ levels cause cardiac myocyte injury that is increased with the decline in pH.1 Dysregulated mitochondrial Ca2+ level and its imbalances generate ischemia neurodegenerative diseases, neuropsychiatric disorders and cancer.2 Accumulation of extra calcium in mitochondria also increases production and modulation of reactive oxygen species. Therefore, balanced Ca2+ buffering is required for normal mitochondrial functions, cell survival and longevity. Mitochondria also involve in control of cell cycle and cell growth. Hence, excessive calcium influx increases ROS generation, induces mitochondrial depolarization and triggers sever pathogenesis. Contrary to this low calcium level affects homoeostasis and redox signaling.3 It also gives rise stress particularly, nitrosative or oxidative stress. More often, excessive calcium uptake of calcium and accumulation of it in cardiac muscle cells result in mitochondrial dysfunctions that impose heart disease. Mitochondria play a central role in cell life and cell death. Availability of Ca2+ in cell from endoplasmic reticulum plays a pivotal role in cell proliferation.
线粒体是产生ATP的重要细胞器,ATP是所有生理和代谢活动的唯一能量分子。它提供细胞能量,并协助信号传导、细胞代谢、细胞分化、细胞存活和其他细胞特异性功能。钙的摄取通过电压依赖性阴离子通道通过线粒体外膜进行。电化学梯度和平衡形成后,双方线粒体功能恢复正常。它在氧化磷酸化过程中得到维持。因此,缓冲细胞质Ca2+水平调节线粒体效应功能。Ca2+转运到线粒体调节其代谢并引起线粒体膜的短暂去极化。Ca2+水平失衡引起心肌细胞损伤,心肌细胞损伤随ph的下降而加重。线粒体Ca2+水平失调及其失衡可导致缺血性神经退行性疾病、神经精神疾病和癌症线粒体中额外钙的积累也增加了活性氧的产生和调节。因此,平衡的Ca2+缓冲是正常线粒体功能、细胞存活和长寿所必需的。线粒体还参与控制细胞周期和细胞生长。因此,过量的钙内流增加ROS的产生,诱导线粒体去极化并引发严重的发病机制。相反,低钙水平会影响体内平衡和氧化还原信号它也会引起压力,尤其是亚硝化或氧化应激。更常见的是,钙的过量摄取和钙在心肌细胞中的积累导致线粒体功能障碍,从而导致心脏病。线粒体在细胞的生命和死亡中起着重要的作用。细胞内质网Ca2+的获取在细胞增殖中起关键作用。
