BACKGROUNDCandidal esophagitis is the primary infection among all digestive tract opportunistic ones in acquired immunodeficiency syndrome (AIDS) cases. X-ray manifestation reports of it are still rare. This study aimed to conduct a retrospective analysis on the X-ray data of 6 AIDS cases complicated with candidal esophagitis, and to study the X-ray characteristics of it combined with the findings from gastroscopy.

METHODSAmong 6 cases in this series, all cases were confirmed by Shenzhen Center for Disease Control and Prevention (CDC) to be HIV positive and all of them had CD4 cell counts less than 150 × 10(6)/L. All cases underwent X-ray and gastroscopy, and mycelium were found in the mucous membrane of the esophagus.

RESULTSIn this series, the findings of the X-ray were as follows: (1) Affected areas: Four cases in the whole esophagus, 2 cases in the middle and lower part of esophagus; (2) Abnormal motivity: Six cases had decreased tension, loose walls, weakened peristalsis, decreased number of peristalsis waves and delayed emptying of barium; (3) Abnormal contour: Six cases had the sign of "decorative border" or "brush", two cases had narrowed canal; (4) Abnormal membrane and "cobblestone sign": Six cases had thickened membrane and "cobblestone sign" on the surface of the abnormal membrane. The hyperemia of mucosa was covered tightly with yellow-white pseudomembrane spots. This was in accordance with the small cobblestone-like filling defect found by X-ray.

CONCLUSIONSIf the AIDS cases have dysphagia, and X-ray shows that more than two sections of the esophagus are affected, with decreased motility, the walls in the sign of "brush" or "decorative edges", thickened membrane with "cobblestone sign", candidal esophagitis is highly possible.

Chinese medicinal authentication is fundamental for the standardization and globalization of Chinese medicine. The discipline of authentication addresses difficult issues that have remained unresolved for thousands of years, and is essential for preserving safety. Chinese medicinal authentication has both scientific and traditional cultural connotations; the use of scientific methods to elucidate traditional experience-based differentiation carries the legacy of Chinese medicine forward, and offers immediate practical significance and long-term scientific value. In this paper, a path of inheritance and innovation is explored through the scientific exposition of Chinese medicinal authentication, featuring a review of specialized publications, the establishment of a Chinese medicine specimen center and Chinese medicinal image databases, the expansion of authentication technologies, and the formation of a cultural project dedicated to the Compedium of Materia Medica.

The TCM (traditional Chinese medicine) transdermal plaster (also known as "cataplasma") are flexible adhesive patches used for treatment of pain, resulted from arthritis, sprain and bruise, tendovaginitis, lumbar spine protrude, neuralgia, hyperosteogeny ache, abdominal discomfort and metastatic cancer, etc. Since the 1980's, investigators in China have used this modern patch delivery system for herbal drugs and obtained satisfactory results especially from the treatment of various types of pain associated with bone diseases, abdominal discomfort, and tumors, etc. The production of TCM cataplasma was successfully scaled up in early 90's and the commercial product line for an antirheumatic agent was first established in Shanghai by Leiyunshang Group. Thus far, a number of products in the form of TCM cataplasma became commercially available in the market, and clinical investigations with these products indicated that topically applicable herbal preparations, especially in the form of cataplasma, are preferred formulations with respect to the treatment comfort of the patient. Compared to the traditional preparations which utilize rubber and rosin as adhesives, cataplasma is advantageous in that the lipophilic and hydrophilic ingredients of the herbal extracts are solubilized and then "gellified" with the organic polymers, and that the drug matrix containing up to 40%-70% of water serves as a "drug reservoir" that will sustain the quick and continuous release of herbal ingredients over several days across the skin. While there are conventional remedies for palliation of pain and discomfort associated with bone diseases or cancers, administration of oral medicinal herbs combined with topical agents such as TCM cataplasma may significantly alleviate the symptoms and improve their quality of life. This article provides a review on three aspects, which include the process development, characteristics and developmental status of TCM cataplasma, and future development of such a technology.

Purpose::Terminal performance of a bullet in human body is critical for the treatment of gunshot injury and optimization of bullet design. The effects of the impact velocity ( v0) and the impact attack angle ( δ0) of the bullet on its terminal performance was investigated, using a new evaluation method (called expansion method) based on the expansion of cracks and the permanent cavity wall in ballistic gelatin. Methods::Ballistic gelatin was used to simulate human body. The 7.62 mm × 39 mm rifle bullets with different v0 (600-760 m/s) and δ0 (0°-6°) were fired into the gelatin blocks. The gelatin block was cut into slices of about 20 mm thickness. The cracks and the permanent cavity on each slice were obtained manually. The damaged gelatin was determined using two methods: expanding the permanent cavity but ignoring the cracks, and expanding both the permanent cavity and the cracks. The relations between the damaged gelatin and v0 and δ0 were obtained using linear fitting method. Results::According to the distribution of the damaged gelatin along the penetration depth, the damaged gelatin block could be divided into two parts: the less damaged part and the severely damaged part. The length of the less damaged part depends mostly on δ0; while the average damaged area of this part depends on both δ0 as well as v0. The cracks contributed significantly to the total volume of damaged gelatin, particularly when the expansion was larger than 1.9 mm. The total damaged gelatin increases with v0, δ0 and the expansion extent. The average length of equivalent cracks grew with v0 and δ0 when considering the cracks, and decreased with v0 when ignoring the cracks. Conclusion::The expansion method is suitable to investigate the influence of different factors of bullets on their terminal performance. The characteristics of the damaged gelatin have a linear relationship with the initial attack angle ( δ0) and the initial velocity ( v0) of the bullet.
