目的观察不同部位皮肤血管结构和形态差异,研究年龄对真皮微循环功能的影响。方法采用活体电视毛细血管镜 (IntravitalVideo-capillaroscopy)和激光多谱勒血流仪(laserDopplerflowmetry)对50名年龄在20～74岁 ,光皮肤类型为II～III型白人女性志愿者的前额、眼角、前臂内侧和手背血管作初步观察。并用计算机图象处理技术 ,对前臂和手背活体真皮血管密度作定量分析。结果真皮乳头毛细血管襻在活体电视毛细血管镜下为点状或逗点状 ;乳头下的血管丛表现为线条状或网状 ;年轻人皮肤血管排列整齐 ,年龄较大者血管扩张增粗、扭曲 ,排列不规则。年龄与襻状血管数、襻状血管面积显著负相关 ;与襻状血管间距、平行血管总长正相关 ;真皮血流量面部高于肢端 ;随年龄的增加真皮血流有逐渐增加趋势。结论年龄影响真皮微循环的形态和功能。两种无创性检测技术联合应用能动态研究活体真皮血管的形态和结构 ,在皮肤血管性疾病的诊断和治疗方面有较高的应用前景。

背景:虽然只有有限的资料,但是人们通常认为欧洲人和亚洲人有不同的皮肤老化特征。目的: 进行本研究是为了评价年龄和阳光照射对亚洲人皮肤老化主要临床特征的影响。方法:由同一个皮肤学家对160名中国妇女和160名年龄相当的法国妇女(年龄范围:20—60岁)进行了临床检查和打分。对面部皱纹(鱼尾纹、眉间皱纹和嘴周围的皱纹)和色斑(面部和手)进行了现场评定,并且拍摄了标准面部照片。终生的太阳照射量是根据调查表上的回答估计的。在年龄相差10岁的各组之间进行了比较。结果: 结果表明,中国女性面部皮肤出现皱纹的时间大约比法国女性晚10年。在以后的时间里,法国女性面部皱纹的增加速率是线性的;而中国女性则是非线性的,似乎在40和50岁之间经历了一个快速老化过程。色斑密集度对中国女性是一个更加重要的老化特征(40岁以后的女性有30％是严重的),而对法国女性不那么重要(不论岁数,严重的少于8％)。结论:这些最初的结果着重指出,在我们研究的中国和法国女性中,主要的皮肤老化特征(皱纹,色斑)进展情况是不同的。这些结果要求由涉及更大群体的多个医学中心的广泛研究加以确认。

HIV is a retrovirus that infects and impairs the cells and functions of the immune system. It has caused a great challenge to global public health systems and leads to Acquired Immunodeficiency syndrome (AIDs), if not attended to in good time. Antiretroviral therapy is used for managing the virus in a patient’s lifetime. some of the symptoms of the disease include lean body mass and many opportunistic infections. This study has developed a sIAT mathematical model to investigate the impact of inconsistency in treatment of the disease. The arising non-linear differential equations have been obtained and analyzed. The DFE and its stability have been obtained and the study found that it is locally asymptotically stable when the basic reproduction number is less than unity. The endemic equilibrium has been obtained and found to be globally asymptotically stable when the basic reproduction number is greater than unity. Numerical solutions have been obtained and analyzed to give the trends in the spread dynamics. The inconsistency in treatment uptake has been analyzed through the numerical solutions. The study found that when the treatment rate of those infected increases, it leads to an increase in treatment population, which slows down the spread of HIV and vice versa. An increase in the rate of treatment of those with AIDs leads to a decrease in the AIDs population, the reverse happens when this rate decreases. The study recommends that the community involvement in advocating for consistent treatment of HIV to curb the spread of the disease.
