雄激素性脱发是一种人群中常见的损容性疾病,其发病与多种因素有关,而遗传因素在发病率中具较大的影响。低能量激光疗法(Low-Level Laser Therapy)是近年来用于治疗雄激素性脱发的光疗技术。低能量激光是一种低能量,短波长的激光,因早期研究发现其具有促进毛发生长的作用而被用于研究治疗雄激素性脱发(AGA)。在低功率激光疗法中,通过使用低能量激光照射毛囊,使毛囊炎性反应得以减轻,同时促进细胞新陈代谢,从而使休止期毛囊复苏,达到促进毛发生长的作用。本文通过对低能量激光疗法治疗雄激素性脱发的机制及效果进行论述,并讨论局部治疗、系统治疗等其他方法联合低功率激光在AGA治疗中的研究进展。

Androgenetic alopecia is a common and ashamed disease in the human population. Its incidence is related to a variety of factors, and the gene have a greater impact on the incidence. Low-level laser therapy LLLT is a phototherapy technique for the treatment of androgenetic alopecia in recent years. Low-level laser means low-energy, short-wave length that have been used for research and treatment of androgenetic alopecia because of the early discovery which is promoting hair growth. In LLLT, the laser irradiates hair follicles, so that reduces the folliculitis, while promoting cell metabolism.From this, the dormant hair follicles resume growth. This article discusses the mechanism and effect of low-level laser therapy for the treatment of androgenetic alopecia, and further discusses the advancement of topical treatment, systemic treatment, and other methods which combined with low-level laser in the treatment of AGA.

宫内发育迟缓(IUGR)又称小于胎龄儿(SGA),不仅影响近期健康,且对远期健康和生长发育具有重要影响,成年后2型糖尿病、肥胖、高血压、冠心病等代谢综合征的发病率明显增高。可能的机制是在生命早期个体对不利的刺激高度敏感,产生基因表达的异常,影响内分泌系统,从而对某些器官的结构或功能产生长期或永久性的影响。我们需从做好产前母体的营养与健康管理、小于胎龄儿出生后的系统管理、喂养选择纯母乳喂养等措施减少疾病的发生。

Intrauterine growth retardation (IUGR), also known as the small for gestational age (SGA), not only affects the recent health and has an important influence on long-term health and growth development. They are more easy to get the metabolic syndrome such as adult metabolism of type 2 diabetes, obesity, hypertension, coronary heart disease. Possible mechanism is produced in the early life of individual, is highly sensitive to adverse stimuli gene expression abnormalities which affecting the endocrine system, thus it have a long-term or permanent impact on the structure and function of some organs. We need to do more in prenatal maternal nutrition and health management, system management of SGA infants, pure breast feeding. Thus these could reduce the occurrence of metabolic syndrome.

瘦素是维持人体能量代谢平衡的蛋白质,在人体中主要由白色脂肪组织分泌,通过与瘦素受体结合发挥作用。近年来有许多与瘦素相关的研究证明高血压患者及代谢综合征患者的血清瘦素水平较健康人群明显升高。两种疾病均可出现心室肥厚,蛋白尿,动脉粥样硬化等表现,说明二者存在共同的靶器官。瘦素代谢异常可出现瘦素抵抗并通过影响肾素-血管紧张素-醛固酮系统(renin angiotensin aldosterone system, RAAS)及炎症细胞因子来损伤靶器官。本文旨在总结瘦素在高血压及代谢综合征中的作用机制,并探讨瘦素对高血压合并代谢综合征靶器官损伤作用的研究进展。

Leptin is a protein that maintains the balance of energy metabolism in human body. It is mainly secreted by white adipose tissue in human body. In recent years, many studies have shown that the serum leptin level in patients with hypertension complicated with metabolic syndrome is significantly higher than that of healthy people. Both of the diseases can lead to left ventricular hypertrophy, proteinuria, atherosclerosis and other manifestations. The abnormal metabolism of leptin may contribute to leptin resistance which damages target organs by affecting the angiotensin aldosterone system and inflammatory cytokines. The aim of this article is to summarize the mechanism of leptin in hypertension and metabolic syndrome, and to explore its effect on the target organ damage in patients with hypertension complicated with metabolic syndrome.

环孢素A(cyclosporin A,环孢素A)是强效的免疫抑制剂,常用于抑制器官移植后的排斥反应,器官移植后新发糖尿病与免疫抑制剂的使用有关。除器官移植,环孢素A还被用于治疗其他自身免疫性疾病,例如1型糖尿病。但环孢素A对胰岛β细胞和其他多种器官有毒副作用,长期使用环孢素A会导致胰岛素抵抗和胰岛β细胞功能损伤,这也是器官移植后糖尿病(post-transplant dibetes mellitus,PTDM)的主要原因。因此在糖尿病领域环孢素A的使用需要对病情进行具体分析和仔细斟酌。

Cyclosporin A (CsA) is a powerful immunosuppressant that is widely used to prevent organ rejection and to treat several autoimmune diseases, such as type 1 diabetes mellitus. Post-transplant diabetes mellitus (PTDM) is related with immunosuppressant. Moreover, there are many toxicity and side effects of CsA on pancreatic β cell and other organs, Long-term treatment of CsA may cause insulin resistance and β cell dyfunction. That's the main reason for post-transplant dibetes mellitus (PTDM). In diabetes mellitus fields, CsA must be used carefully considered.

国际功能、残疾和健康分类(international classification of functioning, Disability and Health,ICF)是一种可用于描述健康状况和与健康有关的状况的国际分类。本文回顾了2001年至今开发的ICF检查表、特定疾病的ICF核心组合、通用型ICF组合以及ICF功能障碍组合的研究状况,指出ICF在使用过程中的不足与缺陷,认为应完善ICF内容,并在国际范围内促进各类ICF组合在临床、科学研究中的应用。

International classification of functioning, disability and health (referred to as ICF) can be used to describe the health status and health-related conditions. This article reviewed ICF checklist, ICF core sets for specific diseases, generic ICF set and ICF disability set since 2001 and pointed out the deficiencies of ICF. More contents should be added to ICF. The international application of ICF sets in clinical medicine and researches will be expanded.

飞秒激光辅助的SMILE因其微创、准确性、安全性、可预测性、稳定性好的特点越来越受患者和术者的欢迎,随着大家对手术的期望值增加,视觉质量成为反应手术效果极其重要的因素之一,而高阶像差又是评定视觉质量尤为重要的指标。本文对飞秒激光SMILE的眼高阶像差及其影响因素进行综述。

Femtosecond laser-assisted SMILE is more and more popular with patients and the operators because of the minimal invasion, efficacy, safety, predictability and stability. But with the increase of people's expectations of the surgery, visual quality become one of the important factors which reacts operation effect extremely, and higher-order aberration is an especially important index when evaluate the visual quality. In this paper, the higher-order aberration and its influence factors of femtosecond laser-assisted SMILE were summarized.

肺动脉高压是一类发病率低,但常引起右心衰竭等最终导致患者死亡的严重肺血管疾病,其形成的主要病理改变是肺血管重构和肺血管收缩,多种细胞因子异常作用参与发病,对该作用机制的研究成为了治疗疾病,改善疾病预后的关键。

Pulmonary hypertension is a kind of low incidence, but it is often caused by right heart failure and other serious pulmonary vascular disease. The main pathological changes of pulmonary vascular include remodeling and pulmonary vascular contraction, and many kinds of cytokines are involved in the pathogenesis of disease, which is the key to improve the prognosis of the disease.

急性肾损伤(acute kidney injury,AKI)是由各种因素导致的临床综合征,尽管科学在发展,发病率、死亡率一直居高不下,并且严重影响患者的预后,这主要是由于对肾脏损伤的早期诊断缺乏敏感的、特异性的指标,使得患者错过了最佳的治疗窗口。研究发现在AKI的早期给予干预,能够明显提高患者的预后,达到满意的治疗效果。所以AKI的早期诊断是提高患者的生活质量的关键措施,期间出现了一系列AKI 的早期分子标志物,包括NGAL、IL-18、miRNA、KIM-1、NAG、L-FABP、TIMP-1、IGFBP-7、TFF-3、GST-π、MYL12B等。本文就这些AKI分子标志物进行总结,阐述这些分子标志物在AKI 诊断及预后预测中的价值,以便于及早制定有针对性的 AKI 治疗及护理策略,使早期诊断、早期干预 AKI 成为可能。
