Comparing the clinical application values of the Degree of Ulcerative Colitis Burden of Luminal Inflammation(DUBLIN)score and Ulcerative Colitis Endoscopic Index of Severity(UCEIS)in patients with ulcerative colitis

Background:The significance of endoscopic evaluation in the diagnosis and management of ulcerative colitis(UC)has been widely recognized.Over the years,scholars have established several endoscopic scores.Herein,we assessed the clinical application value of the Mayo Endoscopic Subscore(Mayo ES),the Degree of Ulcerative Colitis Burden of Luminal Inflammation(DUBLIN)score,and the Ulcerative Colitis Endoscopic Index of Severity(UCEIS)score in UC patients,by comparing their correlation with disease activity and their predictive potential for treatment response and clinical outcomes.Methods:UC patients hospitalized from September 2015 to September 2019 were retrospectively analysed.We employed Spearman’s rank correlation coefficient to assess the linear association of the assessed endoscopic scores with the clinical parameters.The receiver-operating characteristic curve was applied to evaluate the predictive capabilities of the endoscopic scores for treatment escalation and 1-year readmission.Results:A total of 178 patients were enrolled;most of them(82%)suffered moderate or severe colitis.Among them,48(27%)patients received treatment escalation and 59(33%)were readmitted within 1 year.The DUBLIN and UCEIS scores demonstrated higher correlations with clinical parameters than the Mayo ES.The DUBLIN scores significantly differed between patients with mild,moderate,and severe colitis(all P<0.001).The UCEIS scores demonstrated the best predictabilities for treatment escalation and 1-year readmission with an area under the curve of 0.88 and 0.75,respectively.Compared to the UCEIS and DUBLIN scores,the predictive capabilities of the Mayo ES for treatment escalation(both P<0.001)and 1-year readmission(P<0.001 and P紏0.002,respectively)were lower.The UCEIS scores exhibited a significant difference between the steroid-responsive group and the steroid-dependent or steroid-refractory group(both P<0.001),while no significant differences in the Mayo ES and DUBLIN scores were found among the three groups(both P>0.05).Conclusion:This study demonstrates that both the DUBLIN and UCEIS scores outperform the Mayo ES in assessing disease severity and predicting treatment response and clinical outcomes in UC patients.

Psychosomatic skin disease treated by acupuncture and moxibustion

Based on the theory of "regulating body" integrated with "regulating mind",following the principle of "treating the body and mind simultaneously,treating both symptoms and root causes",Prof.Shao-jun WANG adopts flexibly the different techniques,including body acupuncture,wrist-ankle acupuncture,umbilical acupuncture,fire needling,moxibustion,and cupping,etc.for the treatment of psychosomatic skin diseases.According to the manifestations of skin diseases in different stages,she adopts different acupuncture and moxibustion techniques for the comprehensive treatment of psychosomatic skin diseases,including senile pruritus,alopecia areata,neurodermatitis,eczema,urticaria,and acne,on the basis of syndrome differentiation and different acupoint selections,and achieves good results.

Involvement of RNA helicase p68 in skin wound healing process in rats

Purpose： RNA helicase p68 plays an important role in organ development and maturation through tuning cell proliferation. However, the character and role of p68 in the whole wound healing process need more study. Methods： First, we characterize expression of p68 in normal rat skin development postnatal. Then, we assayed dynamic change of p68 in rat skin from different stage after injury, and explored the role of p68 in proliferation and migration of three types of wound healing related cells. Results： p68 was down-regulated during skin developmental and maturation process, up-regulated after wound, peaked on day 14 and then significantly decreased. Wound fluid enhanced wound healing related cell proliferation and up-regulated expression of p68. Conversely, reducing p68 expression by RNA interference resulted in significantly slower proliferation and migration. Conclusion： Our results define an important role of RNA helicase p68 in skin wound healing process.
