Many seminal advances have been made in human immunodeficiency virus (HIV)/AIDS research over the past four decades. Treatment strategies, such as gene therapy and immunotherapy, are yielding promising results to effectively control HIV infection. Despite this, a cure for HIV/AIDS is not envisioned in the near future. A recently published academic study has raised awareness regarding a promising alternative therapeutic option for HIV/AIDS, referred to as "selective elimination of host cells capable of producing HIV" (SECH). Similar to the "shock and kill strategy," the SECH approach requires the simultaneous administration of drugs targeting key mechanisms in specific cells to efficiently eliminate HIV replication-competent cellular reservoirs. Herein, we comprehensively review the specific mechanisms targeted by the SECH strategy. Briefly, the suggested cocktail of drugs should contain (i) latency reversal agents to promote the latency reversal process in replication-competent reservoir cells, (ii) pro-apoptotic and anti-autophagy drugs to induce death of infected cells through various pathways, and finally (iii) drugs that eliminate new cycles of infection by prevention of HIV attachment to host cells, and by HIV integrase inhibitor drugs. Finally, we discuss three major challenges that are likely to restrict the application of the SECH strategy in HIV/AIDS patients.

海绵状血管瘤多为先天性发育不良的血管畸形,个别报道还认为其与遗传、辐射、外伤、妊娠有关[1-5].然而发生于外伤后的椎管内硬膜外海绵状血管瘤（SECH）比较少见.现报告本院2017 年10月收治的1 例外伤后胸椎SECH,并对PubMed、中国知网、万方数据、维普网等数据库近10 年来已报道的国内外该类型病例进行文献复习,着重探讨SECH的病因、临床表现、诊断与治疗,以提高临床医师对本病的认识.
