Use of ritonavir in the manufacture of a medicament for the treatment of human cytomegalovirus infection. Ritonavir is used to inhibit replication of the HCMV immediate early phase. By targeting the HCMV immediate early protein 1, it is stifled at an early stage in the initiation of the HCMV viral gene expression program. This mechanism, which acts upstream in the viral life cycle, offers new possibilities for the treatment of HCMV infection.

This invention is a divisional application of application number 202010500967.1. The invention relates to a layered double hydroxide material system, its preparation method, and its application, specifically the application of LDH / EDTA layered double hydroxide materials in the preparation of antitumor drugs. The LDH / EDTA layered double hydroxide material is a zinc-aluminum layered double hydroxide loaded with ethylenediaminetetraacetic acid (EDTA); in the EDTA-loaded zinc-aluminum layered double hydroxide, EDTA is anion-exchange-intercalated into the interlayer space of the zinc-aluminum layered double hydroxide; the surface of the EDTA-loaded zinc-aluminum layered double hydroxide is positively charged.

The present application relates to the field of medical devices, and provides an ablation catheter and an ablation system comprising the same, the ablation catheter comprising a penetrating part, an ablation main body, a catheter main body and a control handle connected in sequence; the penetrating part comprises a screwing-in member capable of screwing into and being fixed to a target tissue under the action of an external force; the ablation main body comprises an ablation electrode, a connecting member and a temperature sensor; the catheter main body comprises a non-ablation electrode and a perfusion channel; the non-ablation electrode is arranged in a spaced manner with the ablation electrode, and the non-ablation electrode is not in contact with the target tissue during ablation. By using the ablation catheter and the ablation system, the thickened interventricular septum is screwed and ablated, the screwing speed is easier to control, the depth can be stopped or adjusted in time before penetrating the myocardial wall, myocardial perforation can be prevented, and the damage to the myocardial tissue is reduced through temperature detection and perfusion function.
