ObjectiveTo investigate the clinical efficacy and safety of iguratimod combined with the Chinese medicine Runzaoling in the treatment of primary Sjögren's syndrome （pSS）. MethodSeventy-two patients treated in the Department of Rheumatology and Immunology of the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine（TCM） from January 2021 to June 2022 who met the Western medical diagnosis of pSS and had the TCM syndrome of Yin deficiency and heat toxin syndrome were randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group was treated with iguratimod combined with Runzaoling， and the control group was treated with iguratimod. The treatment in both groups lasted for 12 weeks. The clinical symptoms， EULAR Sjogren's syndrome patient reported index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， erythrocyte sedimentation Rate （ESR）， C-reactive protein （CRP）， immunoglobulin （IgG）， Schirmer score， and saliva flow of the two groups were determined before and after treatment. Furthermore， the incidence of adverse reactions was compared between the two groups. ResultThe total response rate in the observation group was 75.0% （27 patients with response and 9 patients with no response）， which was higher than that （61.11%， 22 patients with response and 14 patients without response） in the control group （P<0.05）. After treatment， the ESSPRI， ESSDAI， and TCM syndrome scores in both groups decreased and the decreases were more obvious in the observation group than in the control group （P<0.05）. The treatment in both groups recovered the ESR， CRP， IgG， Schirmer score， and saliva flow （P<0.05）. Moreover， the observation outperformed the control group in terms of the ESR， CRP， IgG， and saliva flow （P<0.05） and had no significant difference in the Schirmer score compared with the control group. During the treatment period， 2 patients in the observation group had nausea， and 1 patient had an abnormal liver function， which were relieved after symptomatic treatment and did not affect the treatment. In the control group， 1 patient withdrew from the study due to rashes and showed no special discomfort in the follow-up 4 weeks， and 1 patient had nausea， which was relieved after symptomatic treatment. ConclusionIguratimod combined with Runzaoling has good clinical efficacy and safety in the treatment of pSS.

Effects of Interaction Between Carbon Nanotubes on Membrane-Wrapped Carbon Nanotubes / 医用生物力学

Objective For the system of two single-walled carbon nanotubes (CNTs) placed in parallel onto a cell membrane, effects of the interaction between carbon nanotubes on wrapping manner of carbon tubes by the membrane were investigated, and the energy-optimized configurations were obtained. Methods A physical model for membrane-wrapped CNTs considering the interaction between two CNTs, and parameters describing the morphology of cell membrane and positions of CNTs were introduced. The Helfrich model based on continuum mechanics was used to calculate the membrane’s bending energy and the Lennard-Jones potential was introduced to describe the interaction between CNTs. Free energy of the system at different distances of NTs was calculated by the look-up table method, and the typical configurations of the membrane-wrapped CNTs was obtained. Results Compared with the case wherein the interaction between CNTs was not considered, the free energy profile of the system significantly changed. Deep well appeared on energy curve, when the distance between CNTs of carbon was 0.3 times of the tube diameter; as the distance between CNTs increased, the energy returned to the case wherein the interaction between CNTs was not considered. Conclusions With introduction of the interaction between CNTs, the wrapping manner of CNTs by the cell membrane changed, and the two CNTs tended to contact during their endocytosis. These results provide theoretical references for understanding and developing novel nanotube-based system for drug delivery.
