Objective​ To evaluate the clinical characteristics and influencing factors of fatigue in patients with rheumatoid arthritis （RA）， with the aim of providing guidance for clinical treatment. Methods​ Based on the multicenter real-world cohort of the China Registry of Traditional Chinese Medicine for Rheumatism （CERTAIN） platform， patients with RA enrolled from 2019 to 2025 were included. Demographic data， disease assessment indicators， laboratory indices， and traditional Chinese medicine （TCM） syndrome patterns were collected to analyze the TCM syndromes and clinical characteristics of RA patients with fatigue. Spearman correlation analysis and logistic regression analysis were used to identify factors associated with fatigue in RA. Results​ A total of 3 021 patients with RA were included， among whom 2 007 （66.43%） had fatigue. Compared with the non-fatigue group， the fatigue group was older and had a longer disease duration， with significantly higher scores for the 28-joint Disease Activity Score （DAS28）， swollen joint count （SJC）， tender joint count （TJC）， Health Assessment Questionnaire （HAQ）， pain visual analog scale （VAS）， and patient global assessment （PGA） （P<0.01）. Among TCM syndromes， fatigue was more common in patients with dampness-heat obstruction， cold-dampness obstruction， and liver-kidney deficiency syndromes （P<0.05）. Multivariate analysis revealed that morning stiffness duration exhibited a stepwise association with fatigue， while poor appetite， insomnia with frequent dreaming， restlessness， high HAQ scores， and high pain VAS scores were identified as risk factors. ConclusionFatigue is a prominent symptom in patients with RA and is more common among those with dampness-heat obstruction， cold-dampness obstruction， and liver-kidney deficiency syndromes. It is closely associated with disease activity， pain， functional limitation， sleep， and emotional status.

Objective To investigate the effect of free toe transplantation in finger reconstruction.Methods Free toe transplantations were performed in 164 patients (185 fingers) suffering from finger defection.There were 134 males and 30 females,aged at 12-83 years [mean (44.8 ± 11.2)years].Finger deletion severity was classified as grade Ⅰ in one case,grade Ⅱ in 18,grade Ⅲ in 23,grade Ⅳ in 49,grade Ⅴ in 54,and grade Ⅵ in 19.According to Gilbert standards,dorsal metatarsal arteries were classified as type Ⅰ in 68 cases,type Ⅱ in 84,and type Ⅲ in 12.Survival ratio of the transplanted fingers and hand function rehabilitation were observed.Results The transplanted toe survived in 160 cases (173 fingers).They composed of all the cases of grade Ⅰ-Ⅴ finger deletion and 15 cases of grade Ⅵ finger deletion; all the cases of type Ⅰ dorsal metatarsal arteries,83 cases of type Ⅱ dorsal metatarsal arteries and nine case of type Ⅲ dorsal metatarsal arteries.Transplantation failed in four cases (12 fingers) of grade Ⅵ finger defection including one case of Gilbert Ⅱ dorsal metatarsal arteries and three cases of Gilbert Ⅱ dorsal metatarsal arteries.Postoperative results were excellent in 110 cases and good in 50.Conclusions Toe transplantation is helpful to restore the finger shape and function and the outcome is satisfactory.Anatomic deformation of dorsal metatarsal arteries is the main cause for the failure of finger reconstruction.
