BACKGROUND:There are many reports on the clinical effect of total knee arthroplasty in the treatment of advanced rheumatoid arthritis, but the reports on the effect of total knee arthroplasty on the disease activity in patients with rheumatoid arthritis are rare. Therefore, the more clinical evidences are needed for supporting.
OBJECTIVE:To explore the effect of total knee arthroplasty on disease activity in patients with rheumatoid arthritis.
METHODS:109 patients with rheumatoid arthritis were included;48 cases in the replacement group, and received total knee arthroplasty combined with internal medicine medications;the 61 cases in the drug treatment group were treated with simple internal medicine medications. The rheumatoid factor, blood sedimentation rate and C-reactive protein levels of the patients in two groups were measured before treatment, 1 and 2 years after treatment, and the Ishikawa joint function scoring criteria was used to assess the functions.
RESULTS AND CONCLUSION:There were no significant differences in the rheumatoid factor, blood sedimentation rate and C-reactive protein levels between two groups before treatment (P>0.05). At 1 and 2 years after treatment, the indicators in the drug treatment group were higher than those in the replacement group (P<0.05);the indicators in the two groups at 2 years after treatment were significantly lower than those before treatment (P<0.05). The rheumatoid arthritis symptom scores of the affected joints of the patients in two groups were significantly improved, especial y the pain, swel and subjective attitudes, and the replacement group was better than the drug treatment group (P<0.05). The total knee arthroplasty can affect the disease activity of rheumatoid arthritis in short-term, and the effect of total knee arthroplasty is better than simple drug treatment.

Objective To investigate the influence of hyperactivity, Stereotyped behaviors , self-injury and irritabili?ty on parenting stress and emotions of the caregivers for patients with pervasive developmental disorders (PDDs). Methods Abnormal behaviors during last month were assessed in 138 PDDs patients by using Aberrant Behavior Checklist (ABC) and Conners Index of Hyperactivity (CIH). The parenting stress and the emotional state of the patients’parents were evalu?ated by the Caregiver Strain Questionnaire (CGSQ) and Hospital Anxiety and Depression Scale (HAD), respectively. Re?sults Anxiety, depression and combination of anxiety and depression were present in 6.2%, 17.8%and 29.5%of PDDs caregivers, respectively. The partial correlation analysis showed that CGSQ score of patients’parents positively correlated with CIH score (r=0.201, P=0.023) and stereotyped act (r=0.189, P=0.033) of the patients, and negatively correlated with stereotyped speech (r=-0.219, P=0.013). The anxious mood of parents positively correlated with stereotyped act (r=0.206, P=0.021). Conclusions Anxiety and depression are common in caregivers of PDDs. Except for stereotyped speech, aber?rant behaviors of the PDDs increase parenting stress and worsen anxious mood of caregivers.

BACKGROUND: Previous research has demonstrated that dermal tissue has mesenchymal stem cells, which have a possibility of autologous transplantation. If the mesenchymal stem cells derived from the skin differentiate into lymphocytes under a certain condition, the immune system disease can be solved generally.OBJECTIVE: To investigate the possibility of differentiation of human skin-derived mesenchymal stem cells into lymphocytes. METHODS: Surface marker expression was detected in the 14th passage human skin-derived mesenchymal stem cells using flow cytometry. Transdifferentiation medium of human skin-derived mesenchymal stem cells consisted of human lymphocyte supernatant and fresh human skin-derived mesenchymal stem cells based on the ratio of 7:3. Inverted microscope was employed to observe morphological changes, and flow cytometry was used to detect surface marker expression in the lymphocytes at 1-8 days after induction. Self-marker expression of human skin-derived mesenchymal stem cells was then detected at 3,6, and 9 days after induction.RESULTS AND CONCLUSION: Human skin-derived mesenchymal stem cells stably expressed self-specific marker CD73, Vimentin and so on, but did not express specific markers of hematopoietic system, I.e., CD34, CD45 and so on, lowly expressed HLA-I, but did not express HLA-DR at all. At 3 days after induction, the cell volume significantly increased, cell proliferation rate was significantly lower than before induction, and a lot of cystic-like particles with strong refraction were observed in or between cells. The CD45 lymphocyte expression was not significantly changed, but CD3, CD19, CD16, CD4, and CD8 expression rates of human skin-derived mesenchymal stem cells were linearly increased at 1-4 days after induction and stabilized at 5-8 days after induction. In addition, CD37, CD34, Vimentin, and HLA-DR expressions were not changed at 3, 6, and 9 days after induction, but HLA-I expression rate was gradually increased with the prolongation time of induction. This suggested that human skin-derived mesenchymal stem cells can differentiate into lymphocyte and potentially participate in repairing immune system injury.

Adjunctive interventions for accelerating orthodontic tooth movement have been a hot topic of interest in orthodontics. Prolonged orthodontic treatment is often associated with multiple potential complications, such as decalcification, caries, root resorption, and gingival inflammation. Therefore, applying adjunctive interventions that accelerate orthodontic tooth movement and reduce the duration of orthodontic treatment can provide patients with numerous benefits that are of profound clinical significance. Currently, adjunctive interventions for accelerating orthodontic tooth movement can be divided into two main categories: surgical and nonsurgical. Surgical interventions, represented by corticotomy and modified corticotomy procedures, are the most common in clinical practice and can minimize the treatment duration, augment alveolar bone, and expand the range of orthodontic tooth movement. However, these procedures are inevitably traumatic and have many risks and limitations that prevent them from being widely used in clinical practice. In recent years, multiple modified corticotomy techniques, such as corticision, piezocision, micro-osteoperforation, and discision, have been proposed; these techniques can reduce soft and hard tissue damage and the incidence of postoperative complications and are relatively easy to perform in the clinic. Corticotomy and other improved surgical techniques can shorten the duration of orthodontic treatment to a certain extent and promote the recovery of periodontal health with no adverse effects on periodontal, dental, or pulp tissues. However, in clinical application, several potential side effects (such as periodontal tissue damage, root resorption, loss of pulp vitality, etc) and shortcomings need further research with long-term follow-up.

Unrestrained inflammation is harmful to tissue repair and regeneration. Immune cell membrane-camouflaged nanoparticles have been proven to show promise as inflammation targets and multitargeted inflammation controls in the treatment of severe inflammation. Prevention and early intervention of inflammation can reduce the risk of irreversible tissue damage and loss of function, but no cell membrane-camouflaged nanotechnology has been reported to achieve stage-specific treatment in these conditions. In this study, we investigated the prophylactic and therapeutic efficacy of fibroblast membrane-camouflaged nanoparticles for topical treatment of early inflammation (early pulpitis as the model) with the help of in-depth bioinformatics and molecular biology investigations in vitro and in vivo. Nanoparticles have been proven to act as sentinels to detect and competitively neutralize invasive Escherichia coli lipopolysaccharide (E. coli LPS) with resident fibroblasts to effectively inhibit the activation of intricate signaling pathways. Moreover, nanoparticles can alleviate the secretion of multiple inflammatory cytokines to achieve multitargeted anti-inflammatory effects, attenuating inflammatory conditions in the early stage. Our work verified the feasibility of fibroblast membrane-camouflaged nanoparticles for inflammation treatment in the early stage, which widens the potential cell types for inflammation regulation.
