The prevalence of tuberculosis infection among adolescents born after terminating the Bacillus Calmette–Guérin (BCG) booster vaccination in China was estimated using tuberculin skin testing (TST) and QuantiFERON-TB Gold assay (QFT) to investigate the influence of neonatal BCG vaccination on the performance of TST. Data analysis was conducted for 2831 eligible participants aged 5–15 years from the baseline survey of a population-based multi-center prospective study. The prevalence rates of TST (induration≥10 mm) and QFT positivity were 9.3% (264/2827) and 2.5% (71/2831), respectively. The rate of QFT indeterminate result was 2.2% (62/2831). The overall agreement between TST and QFT was low (concordance= 88.0%; κ coefficient= 0.125). Only TST was positively associated with BCG vaccination with an adjusted odds ratio of 1.71 [95% confidence interval, 1.26–2.31]. A history of close contact with patients of active TB was significantly associated with positivity for TST and QFT. Our results suggested that BCG neonatal vaccination still affects TST performance, and a two-step approach might be considered for TB infection testing among adolescents in China.

Hyperthermia is a condition characterized by increased body temperature as a consequence of failed thermoregulation. Hyperthermia occurs when a body produces or absorbs more heat than it dissipates. Hyperthermia also elicits various effects on the physiology of living cells. For instance, fever-range temperature (39β°C to 40β°C) can modulate the activities of immune cells, including antigen-presenting cells, T cells, and natural killer cells. Heat shock temperature (41β°C to 43β°C) can increase the immunogenicity of tumor cells. Cytotoxic temperature (>43β°C) can create an antigen source to induce an anti-tumor immune response. The immunomodulatory effect of hyperthermia has promoted an interest in hyperthermia-aided immunotherapy, particularly against tumors. Hyperthermia has also been used to treat deep fungal, bacterial, and viral skin infections. We conducted a series of open or controlled trials to treat skin human papillomavirus infection by inducing local hyperthermia. More than half of the patients were significantly cured compared with those in the control trial. A series of challenging clinical cases, such as large lesions in pregnant patients or patients with diabetes mellitus, were also successfully and safely managed using the proposed method. However, further studies should be conducted to clarify the underlying mechanisms and promote the clinical applications of hyperthermia.

全厚皮肤移植对于重建皮肤屏障、促进伤口愈合至关重要,充足的氧气供给与皮肤移植的成功密切相关。然而,全厚皮肤的氧气递送受限于皮肤对氧气的低渗透性。在本篇文章中,构建了产氧缝合线用于促进全厚皮肤的氧气渗透。在皮肤模型的15 mm厚度处,产氧缝合线递送的氧气量是局部气态氧疗的100倍以上。在极端乏氧(< 0.5% O2,v/v)环境下,产氧缝合线可以促进内皮细胞增殖。通过小鼠自体皮瓣移植实验发现,产氧缝合线帮助恢复血液再灌注、促进移植皮肤的存活。产氧缝合线有望在临床中被使用,促进全厚皮肤移植的成功。

微针能直接将治疗药物递送到皮肤病变部位,从而提高治疗效果和降低副作用,因而可用于皮肤疾病的局部治疗。微针可以递送不同种类的治疗药物(如小分子药物、大分子药物、纳米药物、活细胞、细菌和外泌体)来治疗各种皮肤疾病,包括浅表肿瘤、伤口、皮肤感染、炎症性皮肤病和异常皮肤外观。微针的治疗效率可以通过以下几种策略来提高:①整合不同治疗方法的优点来进行联合治疗;②对微针的结构进行仿生设计或者赋予微针内外源响应性释药性能来提高药物的经皮递送效率。一些研究提出将无药物微针发展为一种有前景的机械治疗方法,即通过微针的机械刺激产生机械转导信号来促进伤口愈合、疤痕消退和毛发再生。虽然微针具有诸多优点,但微针的实际应用还存在工业化生产和临床评价难等问题,进而制约微针的临床转化。本文总结了微针在皮肤疾病中的各种应用、新出现的挑战和发展前景,为微针的临床转化思路提供借鉴。

黏合剂作为生物医学工程中的一种先进方式,因其独特的伤口管理行为而备受关注。然而,由于当前的黏合剂系统界面粘合强度较弱,要实现牢固的黏合仍是一项巨大的挑战。此外,传统化学黏合剂缺乏动态适应性,限制了伤口周围的新生细胞向该部分迁移,导致组织再生效果不佳。在此,我们精心设计了一种具有强大黏附力和实时促皮肤愈合效果的细胞外基质衍生的生物复合黏合剂。在嵌合蛋白和天然DNA间超分子相互作用的积极参与下,液-液相分离被很好地用来驱动生物复合黏合剂的组装,从而获得增强的黏合性能。该生物黏合剂具有出色的黏合和止血性能,其中,剪切黏合强度约18 MPa,优于已报道的同类产品。此外,工程生物衍生成分赋予了该黏合材料优异的生物相容性和特殊的生物学功能,包括促进细胞增殖和迁移,因此使用这种材料最终可实现实时原位皮肤再生。这项工作为功能化生物黏合剂工程和生物医学转化开辟了新的途径。
