Abstract
Background: Adequate tissue oxygenation is a key determinant of diabetic foot ulcer (DFU) outcomes. Though transcutaneous oxygen pressure (TcPO2) is the gold standard for evaluating tissue oxygenation, its limited availability restricts routine clinical use. Consequently, toe pressure is frequently utilized as a practical surrogate; however, the direct correlation between these two modalities has yet to be rigorously investigated. This study aimed to assess the correlation and agreement between TcPO2and toe pressure in patients with DFUs.
Methods: A retrospective review was conducted on 837 DFU patients who received simultaneous TcPO2and toe pressure assessments.
The correlation between the two tests was analyzed using the Pearson correlation coefficient, and agreement was evaluated using Bland– Altman analysis. To aid interpretation, a scatterplot and Bland–Altman plot were generated.
Results: TcPO2and toe pressure demonstrated a strong correlation (R=0.66; 95% confidence interval, 0.62 to 0.70; P<0.001). Bland–
Altman analysis showed a mean bias of 26.9 mmHg (standard deviation of differences, 28.8 mmHg; 95% limits of agreement, −28.9 to 82.6 mmHg) between toe pressure and TcPO2, reflecting limited agreement and increased variability at higher perfusion levels.
Conclusion: TcPO2and toe pressure are strongly correlated. However, they are not interchangeable, particularly in DFU patients with high tissue perfusion.

最近，一位来自广西的伤口患者，出院时说：我这个伤口去广西、广州很多大医院看了，都建议截肢，说不可能保肢的因为病史已经8年了，来时是打算试一试的，结果很意外，历时2月，居然保肢成功，还能走路！

关于狂犬病疫苗注射的问题，经常被问到。
不该打的时候打了，花冤枉钱还遭罪；
该打的时候不打，却又是一朝发病，神仙难救。
因此，该不该打的问题，往往让人左右为难，无论是医生还是患者均受此困扰
如果周围有一个狐臭的人，你会远离她，因为那味道让让人很不舒服！
