Abstract
Intraoperatively acquired pressure injuries (IAPIs) occur frequently among patients who undergo surgical procedures that last longer than 3 h. Several studies indicated that heat shock proteins (HSPs) play an important role in the protection of stress-induced damages in skin tissues. Hence, the aim of this study was to investigate the potential preventive effect of thermal preconditioning (TPC) on IAPIs in surgical patients and rats and to identify the differentially expressed HSP genes in response to the above treatment. TPC was performed on one group of hairless rats before the model of pressure injuries was established. Subsequently, the size of skin lesions was measured and the expression levels of mRNA and protein of HSPs of the pressured skin were detected by real-time polymerase chain reaction (RT-PCR), western blot, and immunohistochemical staining. For human studies, 118 surgical patients were randomly divided into the TPC group (n = 59) and the control group (n = 59), respectively. The temperature and pressure of sacral skin, as well as the incidence of pressure injury (PI) were detected and compared. In animal studies, TPC significantly reduced both the size and incidence of PI in rats on the second, third and fourth days post treatment. In addition, the expression levels of both mRNA and protein of HSP27 were increased in the TPC group, compared with the control group. Immunohistochemical staining showed that HSP27 was distributed in various types of dermal cells and increased in basal cells. In human studies, a significant reduction (75%) of IAPIs was observed among the patients in the TPC group. TPC can reduce the incidence of PI in rats and humans, and the upregulation of HSP27 may play an important role in this biological progress. Further studies are warranted to explore the molecular mechanism of the preventive effect in PI mediated by HSP27.

Abstract
In order to elucidate the involvement of DNA damage in the induction of heat shock proteins (stress proteins), we examined the induction of 72-kD heat shock protein (HSP72) in an SV40-transformed human fibroblast cell line (WI38VA13) which was exposed to various DNA-damaging agents, including 1-(4-amino-2-methyl-5-pyrimidinyl)methyl-3-(2-chloroethyl)-3 -nitro-methylmethane sulfonate, N-methyl-N'-nitro-N-nitrosoguanidine, and 4-nitroquinoline-N-oxide. Induction of HSP72 was detected by the indirect immunofluorescence method using a monoclonal antibody. All the DNA-damaging agents used in this study induced HSP72 on human fibroblasts. This result indicates that DNA damage is one trigger for the induction of HSP72.
