Qiju Dihuang pill is one of the common Traditional Chinese Medicine to treat ophthalmic diseases. In vivo studies have suggested that Qiju Dihuang pill can be used for treating glaucoma, and it can also be used clinically to treat cataract patients. However, the bioactive ingredients and the therapeutic mechanism of Qiju Dihuang pill on treating these ophthalmic diseases remained unclear. ⋯ In final, a molecular docking model was constructed to study the interaction mechanism between active components and drug targets at the molecular level. All the findings show that Qiju Dihuang pill achieves therapeutic effects on treating ophthalmic diseases by regulating the crucial targets of the compounds in it. This work not only provides insight into the therapeutic mechanism of herbal medicine in the treatment of ophthalmic diseases from a multiscale perspective, but also offers an effective approach for drug discovery and development of Traditional Chinese Medicine.

Observational Study
Von Willebrand factor (vWF) in patients with heart failure with preserved ejection fraction (HFpEF): A retrospective observational study.
Heart failure with preserved ejection fraction (HFpEF) is associated with endothelial damage and inflammation. In addition, von Willebrand factor (vWF) has been discovered as a biomarker of endothelial dysfunction. Therefore, the study aims to investigate the association between vWF level and HFpEF. ⋯ Further, statistical significance of the analysis remained after adjusting variables such as body mass index, low-density lipoprotein cholesterol, total cholesterol, coronary artery disease, and type 2 diabetes mellitus (β = 0.406, t = 4.579, P < .001; β = 0.323, t = 3.218, P < .001; β = 0.581, t = 6.922, P < .001). Our study shows that elevated vWF levels are associated with HFpEF, and it may serve as a potential biomarker for HFpEF severity. We also found that increased vWF levels are positively correlated to IL-6, TNF-α, and CRP, which may provide a clue for further researching the pathogenesis of HFpEF.

Postoperative assessment of breast reconstruction results has become increasingly important. In this paper, a unique analysis method with 3-dimensional surface images of patients who were treated with immediate breast reconstruction is presented. ⋯ The scores become a relative value that ranges from 0 (completely different) to 100 (completely the same). By expressing the score as a relative value, the breast contour score could help us understand the degree of breast symmetry more intuitively.
