A non-invasive tool for skin disease diagnosis would be a useful clinical adjunct. The purpose of this study was to determine whether visible/near-infrared spectroscopy can be used to non-invasively characterize skin diseases. In-vivo visible- and near-infrared spectra (400-2500 nm) of skin neoplasms (actinic keratoses, basal cell carcinomata, banal common acquired melanocytic nevi, dysplastic melanocytic nevi, actinic lentigines and seborrheic keratoses) were collected by placing a fiber optic probe on the skin. Paired t-tests, repeated measures analysis of variance and linear discriminant analysis were used to determine whether significant spectral differences existed and whether spectra could be classified according to lesion type. Paired t-tests showed significant differences (p<0.05) between normal skin and skin lesions in several areas of the visible/near-infrared spectrum. In addition, significant differences were found between the lesion groups by analysis of variance. Linear discriminant analysis classified spectra from benign lesions compared to pre-malignant or malignant lesions with high accuracy. Visible/near-infrared spectroscopy is a promising non-invasive technique for the screening of skin diseases.

A micro-Raman spectrometer system for use in differentiating tumor lesions from normal skin detects specific characteristics of Raman spectra indicative of cancer. A peak at 899 cm⁻¹ and a higher intensity region in the 1325 cm⁻¹ to 1330 cm⁻¹ range indicate the presence of tumors. The spectrometer system may be applied for skin cancer detection and for mapping the margins of lesions. Cancer detection methods as described herein have achieved diagnostic sensitivity of 95.8% and specificity of 93.8%.

The invention discloses scald and burn dressing prepared by a coaxial electrostatic spinning method. The scald and burn dressing is a nanofiber membrane with a core/shell structure, wherein the shell is made of a natural biological high molecular material and the core is a degradable synthetic high molecular material loaded with astragaloside. The mass ratio of astragaloside to the degradable synthetic high molecular material is 1:(2-50). The invention further discloses a preparation method of the scald and burn dressing. The raw materials are easy to get and cheap, and the preparation process is simple, easy to operate and control and can be easily put into large-scale industrial production.

The invention relates to the technical field of a traditional Chinese medicine preparation, and particularly discloses externally-applied skin-generating oil for treatment of burns and a preparation method and application thereof. The skin-generating oil is prepared by soaking the following 15 Chinese herbs in sesame oil: radix scutellariae, rheum officinale, astragalus mongholicus, coptis chinensis, cortex phellodendri, angelica sinensis, sanguisorba officinalis, lithospermum, rehmannia, radix angelicae, cynanchum atratum, bletilla striata, olibanum, myrrh and borneol. When the skin-generating oil is applied in treatment of burns, wound infection caused after injury can be prevented effectively, proliferation and migration of fibroblasts and vascular endothelial cells can be promoted, neovascularization can be induced, wound healing can be accelerated, scar repair can be promoted, the wound healing time can be shortened, Class I-II burns can be cured in 10-12 days, and Class III burns of rabbits can be cured in 20-25 days. When Class III burns of rabbits are treated with the skin-generating oil, the wound area can be reduced from 6 cm<2> to 0.1cm<2>, the wound surface is flat, smooth and soft, and newborn hair is normal. The wound epidermis can be recovered completely, dense hair follicles can be formed in the dermis layer, and almost no difference from normal skin tissues can be produced.

The NSAID, sulindac and/or its metabolites and derivatives, in combination with hydrogen peroxide or another oxidizing agent, such as arsenic trioxide that generates reactive oxygen species (ROS), significantly enhances the killing of cancer cells. This effect occurs at concentrations of each compound that individually have little or no activity directed against cancer cells. A skin cream has been developed and used to treat skin cancer and precancerous skin growths that effectively removes the lesions with no effect on surrounding normal skin.

For determining autofluorescence of a clinically normal skin issue (7) of a patient, the tissue (7) is irradiated with electromagnetic radiation. An amount of fluorescent radiation emitted by the tissue (7) in response to the irradiation is measured and, in response thereto, a signal is generated which represents a determined autofluorescence in agreement with the measured amount of electromagnetic radiation. Because the tissue (7) is skin tissue (7) in vivo and irradiation is performed noninvasively, a method which is very simple to apply for determining autofluorescence is obtained. An apparatus especially adapted for use in this method is also described.
