Analysis of tongue figure features in 990 cases of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.</p><p><b>METHODS</b>Recruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.</p><p><b>RESULTS</b>Compared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).</p><p><b>CONCLUSIONS</b>The tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.</p>

The effect of ultraviolet irradiation on the biocompatibility of Medpor / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of ultraviolet ( UV) irradiation on the biocompatibility of Medpor.</p><p><b>METHODS</b>The Medpor implant, 2 mm in thickness, was divided into several pieces with the size of 1 cm x 1 cm. 12 Japanese big ear rabbits were divided into experimental (n=6) and control group (n=6). The 1 cm x 1 cm auricular cartilage defects were made in each rabbit ear. Then the defects were repaired with UV-treated Medpor implants in experimental group, and Medpor implants in control group. The levels of the total hemolytic complement (CH50) were measured 3 d hefore operation, and 1, 3, 7, 14, 21, 30, 60, 90 d after operation. The wound healing was observed. 90 d after operation, the animals were killed to get the specimens for gross observation and histologic examination. The change of CH50 level after operation was significantly different between the two groups ( P < 0.05) . The CH50 level was comparatively stable in experimental group. Compared with control group, the local inflammatory reaction was not obvious in experimental group. A great amount of tissue, including big vessels was growing into the mini-pores of Medpor, resulting a close combination between the implant and surrounding tissue.</p><p><b>CONCLUSION</b>It suggests that ultraviolet irradiation can improve the biocompatibility of Medpor and promote the wound recovery.</p>
