北大医院：糖尿病有救了打太极拳可明显改善

太极拳中诺医疗

太极拳能治糖尿病？

糖尿病——严重危害人类健康，是现代疾病中的一大杀手，对人体的危害仅次于肿瘤和心脑血管病。据估计，Ⅱ型糖尿病病人在全世界有两亿五千万人。在我国，它已超越高血压人群、成为第一大高发疾病。其中2型糖尿病约占糖尿病总数的90％～95％。

香蕉是“通便高手”？错！小心越吃越便秘！

转载中诺医疗转自：广州市第一人民医院服务号

春节期间，走亲访友、同学聚会……少不了各种大鱼大肉的饭局，而数餐多荤少素的饮食令不少朋友的肠子已“不堪重负”，加上过年食用煎炸应节食品、坚果等，肠子急需“释放”。

这时，

不少人便想着吃几根香蕉来润肠通便。

然而现实是，有人一口气连吃好几根，

结果却便秘了。

怎么回事，

难道他吃的是假香蕉？

重度渗出糖尿病足溃疡的管理

慢伤前沿中诺医疗

为了有效管理糖足溃疡（DFU）的伤口渗出，临床医生须理解渗出的本质和为何其从急性伤口愈合的必要成分变成了慢性伤口中的有害物质。渗液的管理需要了解患者的整体、考虑引起渗出增加的合并症、给予的治疗、皮肤质量和完整性、以及病人的生活质量。

星期五, 06 9月 2019

渗出物管理是伤口愈合过程管控中非常重要的一个环节，它可能贯穿整个伤口治疗的过程。国际伤口愈合联合会（WUWHS， World Union of Wound Healing Societies）在2007年曾经发布过一份关于渗出物管理的共识文件，时隔十二年，因为各种新的临床护理技术及方法的出现，WUWHS认识到临床需要更多、更新的指导意见，因此组织专家组对旧版本的共识文件进行了更新，并于2019年年初发布了新版文件。华阳医疗临床小组对此份文件进行了编译，因篇幅较长，所以内容将分几期进行转发推送，供各位老师参考，并对其中不足之处做出指正，感谢。

不良情绪对疤痕的影响

中诺医疗

疤痕确实给广大疤友带来了无穷的痛苦，但是看到许多疤痕并不重的，甚至都算不上疤痕的人，大喊压力如何大，如何影响疤痕修复，去疤痕的方法不管用什么的。请你不要大喊，这不叫压力。相比人家脸部的疤痕，相比大面积的疤痕这根本不算什么，相对而言，别人那些大面积疤痕修复更加困难。

Keywords: arginine | chondroitin sulfate | glutamine | skin hydration | TEWL | water-holding capacity

ABSTRACT

Purpose: The study explored the enhanced skin moisturizing capabilities and moisture retention effects achieved by forming a polyion complex using sulfated glycosaminoglycan (GAG), specifically chondroitin sulfate (CS), and amino acids (AA) such as glutamine (Q) and arginine (R). The overall hydration effect of this CS-AA complex was examined.

Methods: After analyzing the CS-AA polyion complex structure using spectroscopic methods, the ex vivo moisture retention ability was assessed under dry conditions using porcine skin samples. Additionally, the efficacy of the CS-AA polyion complex in reducing transepidermal water loss (TEWL) and improving skin hydration was evaluated on human subjects using a digital evaporimeter and a corneometer, respectively.

Results: Validating a systematic reduction in particle size, the following order was observed: CS > CS/AA simple mixture > CSAA complex based on dynamic light scattering (DLS) and transmission electron microscopy (TEM) analysis. Furthermore, observations revealed that the CS-AA complex exhibits negligible surface charge. Additionally, Fourier-transform infrared spectroscopy (FT-IR) analysis demonstrated a distinct peak shift in the complex, confirming the successful formation of the CS-AA complex. Subsequently, the water-holding effect through porcine skin was assessed, revealing a notable improvement in moisture retention (weight loss) for the CS-Q complex: 40.6% (1 h), 20.5% (2 h), and 18.7% (4 h) compared to glycerin. Similarly, the CS-R complex demonstrated enhancements of 50.2% (1 h), 37.5% (2 h), and 33% (4 h) compared to glycerin. Furthermore, TEWL improvement efficacy on human skin demonstrated approximately 25% improvement for both the CS-Q complex and CS-R complex, surpassing the modest 12.5% and 18% improvements witnessed with water and glycerin applications, respectively. Finally, employing a corneometer, hydration changes in the skin were monitored over 4 weeks. Although CS alone exhibited nominal alterations, the CS-Q complex and CS-R complex showed a significant increase in moisture levels after 4 weeks of application.

Conclusion: In this study, polyion complexes were successfully formed between CS, a sulfated GAG, and AA. Comparisons with glycerin, a well-known moisturizing agent, confirmed that the CS-AA complex exhibits superior moisturizing effects in various aspects. These findings suggest that the CS-AA complex is a more effective ingredient than CS or AA alone in terms of efficacy.

Abstract

Background: The delicate periorbital region is susceptible to skin dehydration, wrinkles, and loss of elasticity. Thus, targeted and effective anti-aging interventions are necessary for the periorbital area.

Aim: To evaluate the efficacy and safety of a new anti-aging eye cream formulated with the active complex (Yeast/rice fermentation filtrate, N-acetylneuraminic acid, palmityl tripeptide-1, and palmitoyl tetrapeptide-7).

Methods: The cell viability and expressions of key extracellular matrix (ECM) components of the active complex were evaluated using a human skin fibroblast model. In the 12-week clinical trial, skin hydration, elasticity, facial photographs, and collagen density following eye cream application were assessed using Corneometer, Cutometer, VISIA, and ultrasound device, respectively. Dermatologists and participants evaluated clinical efficacy and safety at baseline, and after 4, 8, and 12 weeks.

Results: PCR and immunofluorescent analyses revealed that the active complex significantly stimulated fibroblast proliferation (p < 0.05) and markedly promote the synthesis of collagen and elastin. Clinical findings exhibited a substantial enhancement in skin hydration (28.12%), elasticity (18.81%), and collagen production (54.99%) following 12 weeks of eye cream application. Dermatological evaluations and participants’ assessments reported a significant improvement in skin moisture, roughness, elasticity, as well as fine lines and wrinkles by week 8.

Conclusion: The new anti-aging eye cream, enriched with the active complex, demonstrates comprehensive rejuvenating effects, effectively addressing aging concerns in the periorbital area, coupled with a high safety profile.
