Anti-ribosomal P protein antibodies and insomnia correlate with depression and anxiety in patients suffering from systemic lupus erythematosus.

Objective: Anxiety and depression in patients with systemic lupus erythematosus (SLE) complicate clinical treatment and can seriously affect prognosis. The present study aims to investigate the effects of the anti-ribosomal P protein antibody (anti-RibP) in the peripheral blood and insomnia on the severity of anxiety and depression in case of SLE. The study compared both the results of the investigation on the objective perceptions of physicians concerning mood changes in patients with SLE and the results of self-rating scales that were completed by the enrolled patients. The conclusion of the comparation is used to determine the probability of the accurate detection of anxiety and depression by physicians. The study aims to assist in the early detection in clinical practice of abnormal emotions in patients with SLE and to summarize common clinical interventions for anxiety and depression. Method: The relationship between anxiety and depression was evaluated by the Zung self-rating anxiety/depression scale (SAS/SDS). Basic information (e.g., blood type, smoking history, drinking history, educational background, duration of illness), the insomnia severity index (ISI) results, and anti-RibP in the peripheral blood, were investigated in 107 patients with SLE in northeastern China to further analyze the correlation between the severity of depression and anti-RibP, together with the consistency between results of the questionnaire for physicians and the self-rating scale for patients. Results: Gender, smoking history, drinking history, educational background, and duration of illness were correlated with the SAS/SDS scores (P < 0.05). Family history had a significant effect on the SAS score (P = 0.031), while the SDS score was significantly correlated with blood type (P = 0.021). The ISI score was significantly and positively correlated with the SAS/SDS score (P < 0.001). The titer of anti-RibP showed a correlation with the SDS score (P < 0.05) but not with the SAS score (P = 0.198). The titer of anti-RibP was significantly higher in patients with major depression compared with those with no depression, patients with mild depression, and those with moderate depression (P < 0.001). Conclusion: Anxiety and depression in patients with SLE were correlated with sleeping, educational background, blood type, smoking history, and alcohol consumption. Although anti-RibP was not significantly correlated with anxiety, it indicated a significant correlation with major depression. Clinicians were more accurate in assessing anxiety compared with depression.

Observation of the clinical efficacy of isotope phosphorus-32 dressing combined with diprospan and mucopolysaccharide polysulphate cream in the treatment of keloids.

OBJECTIVE: The present study aims to investigate the effectiveness, recurrence, and adverse reaction rates of isotope phosphorus-32 dressings combined with diprospan and mucopolysaccharide polysulphate cream in the treatment of keloids. METHODS: A total of 80 patients with keloids admitted to the Dermatology Clinic of the Fourth Affiliated Hospital of Harbin Medical University between June 2019 and June 2021 were included in the present study and randomly divided into three groups: Control Group 1 (n = 27), Control Group 2 (n = 25), and the treatment group (n = 28). Patients in Control Group 1 were treated with diprospan combined with mucopolysaccharide polysulphate cream, patients in Control Group 2 were treated with an isotopic phosphorus-32 dressing combined with mucopolysaccharide polysulphate cream, and patients in the treatment group were treated with an isotopic phosphorus-32 dressing combined with diprospan and mucopolysaccharide polysulphate cream. The effectiveness, recurrence, and adverse reaction rates were observed in all three groups. RESULTS: The treatment group had the most significant decrease in the itching scores. The respective effectiveness, recurrence, and adverse reaction rates were 81.4%, 43.6%, and 74.1% in Control Group 1; 56%, 38.7%, and 64% in Control Group 2; and 96.7%, 11.2%, and 41% in the treatment group. The differences were statistically significant (p < 0.05). CONCLUSION: An isotope phosphorus-32 dressing combined with diprospan and mucopolysaccharide polysulphate cream keloid treatment delivers a fast onset, good effectiveness, and low recurrence and adverse effect rates.

Clinical efficacy evaluation of 595-nm pulsed dye lasers, microwave tissue coagulation, and liquid nitrogen cryotherapy in the treatment of verruca vulgaris in children.

OBJECTIVE: To evaluate the clinical efficacy and safety of 595-nm pulsed dye laser in the treatment of verruca vulgaris in children and to compare the efficacy of this method against two other methods, microwave tissue coagulation and liquid nitrogen cryotherapy. METHODS: A total of 90 children being treated in the dermatology outpatient department of our hospital from 2019 to 2021 were selected and divided into three groups: the treatment group A (n = 30, treated with a 595-nm pulsed dye laser), treatment group B (n = 30, treated with microwave tissue coagulation), and treatment group C (n = 30, treated with liquid nitrogen cryotherapy). All the patients in the treatment group A, treatment group B, and treatment group C were treated once every two weeks, with a maximum of six treatments. RESULTS: The response rate of the treatment group A was 93.3%, which was higher than the 83.3% rate of treatment group B and the 66.7% rate of treatment group C. The average treatment times of the treatment group A (2.45 ± 1.10) were lower than group B (3.51 ± 0.98) and group C (4.63 ± 0.96). The adverse reaction rate in the treatment group A (16.7%) was significantly lower than that in treatment group B (56.7%) and treatment group C (63.3%). The differences were statistically significant (all p < 0.05). CONCLUSIONS: The 595-nm pulsed dye laser is safe and seems to be the most effective treatment for verruca vulgaris in children. Further high-level clinical trial is warranted to verify our results.

A new metabolic signature contributes to disease progression and predicts worse survival in melanoma.

Metabolic reprogramming is a common hallmark of tumor cells and is a crucial mediator of resistance toward anticancer therapies. The pattern of a metabolism-related signature in melanoma remains unknown. Here, we explored the role of a multi-metabolism-related gene signature in melanoma.We used the training and validation sets to develop a multi-metabolism-related gene signature. Cox regression analysis and the least absolute shrinkage and selection operator (LASSO) method were used for constructing a model. The predictive role of the metabolic signature with clinicopathological features of melanoma was also analyzed. Functional analysis of this metabolic signature was also investigated.A ten metabolism-related gene signature was identified and can stratify melanoma into high- and low- risk groups. The signature was correlated with progressive T stage, Breslow thickness, Clark level, and worse survival (all Ps< 0.01). This metabolic signature was shown as an independent prognostic factor and was also a predictive indicator for worse survival in various clinical and molecular features of melanoma. Furthermore, the metabolic signature was implicated in immune responses such as the regulation of T cell activation and cytokine activity. The metabolic signaturewas associated with the progression and worse survival of melanoma. Our study offered a valuable metabolism-targeted therapy approach for melanoma.

Exogenous hydrogen sulfide promotes cell proliferation and differentiation by modulating autophagy in human keratinocytes.

The effects and the underlying mechanisms of hydrogen sulfide (H2S) on keratinocyte proliferation and differentiation are still less known. In the current study, we investigated the effects and the underlying mechanisms of exogenous H2S on keratinocyte proliferation and differentiation. Human keratinocytes (HaCaT cells) were treated with various concentrations (0.05, 0.25, 0.5 and 1 mM) of sodium hydrosulfide (NaHS, a donor of H2S) for 24 h. A CCK-8 assay was used to assess cell viability. Western blot analysis was performed to determine the expression levels of proteins associated with differentiation and autophagy. Transmission electron microscopy was performed to observe autophagic vacuoles, and flow cytometry was applied to evaluate apoptosis. NaHS promoted the viability, induced the differentiation, and enhanced autophagic activity in a dose-dependent manner in HaCaT cells but had no effect on cell apoptosis. Blockage of autophagy by ATG5 siRNA inhibited NaHS-induced cell proliferation and differentiation. The current study demonstrated that autophagy in response to exogenous H2S treatment promoted keratinocyte proliferation and differentiation. Our results provide additional insights into the potential role of autophagy in keratinocyte proliferation and differentiation.
