Objective To observe the clinical efficacy of Lingnan fire needling in the treatment of plaque psoriasis.Methods A total of 60 cases of patients with plaque psoriasis admitted to Bao'an Hospital of Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from August 2021 to January 2023 were selected,and the patients were randomly divided into the observation group and the control group according to the random number table method,with 30 cases in each group.The observation group was given Lingnan fire needling for treatment,and the control group was given topical application of Calcipotriol Ointment.The course of treatment covered eight weeks continuously.After eight weeks of treatment,the clinical efficacy of the two groups was evaluated,and the changes of Psoriasis Area and Severity Index(PASI)scores and Dermatology Life Quality Index(DLQI)scores,as well as the diameter of glomus under dermoscopy of the patients in the two groups were observed before the treatment and after 2,4,6,and 8 weeks of treatment.Changes in Generalized Anxiety Disorder Scale(GAD-7)scores before treatment and after 2,4,6,and 8 weeks of treatment were compared between the two groups.Results(1)After 2,4,6 and 8 weeks of treatment,the scores of PASI,DLQI and GAD-7 of patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(2)The cured and markedly rate of the observation group was 86.67%(26/30);and that of the control group was 66.67%(20/30).The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(3)After 2,4,6,and 8 weeks of treatment,the diameter of glomus under dermoscopy of the patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).Conclusion Lingnan fire needling therapy for plaque psoriasis can effectively improve the clinical symptoms of the patients,relieve the anxiety symptoms induced by skin lesions and itching,so as to improve their quality of life.

Objective To investigate the molecular mechanism of the induction of gastric cancer cell line AGS death by p97 inhibitor eeyarestatin Ⅰ(Eer Ⅰ).Methods AGS cells were treated with Eer Ⅰ.Then liquid chro-matography-mass spectrometry was used to perform proteome analysis for screening differentially expressed proteins and to find underlying signaling pathways.At the same time,the proteins of related pathway were investi-gated by protein immunoblotting.Cell proliferation was detected using the CCK-8 test kit;Cell apoptosis was detec-ted using TUNEL staining test kit;Liperfluo probe was used to detect ferroptosis-related lipid peroxides.Results In Eer Ⅰ treatment group,there were significant changes in proteins(fold change＞1.5 and P＜0.05),in which 125 proteins were increased and 132 proteins were decreased.The enrichment analysis of these DEPs showed that Eer Ⅰ might significantly affect cell apoptosis and ferroptosis-related signaling pathways.Furthermore,Eer Ⅰcould increase genomic DNA fragmentation related to cell apoptosis,increase of lipid peroxides in the ferroptosis pathway,causes changes in cell death related proteins,and inhibit the proliferation of gastric cancer cells.Conclusions p97 inhibitor Eer Ⅰ can induce cell apoptosis and ferroptosis in AGS cells,thereby inhibiting tumor cell proliferation.

Pouchitis is a common complication of ileal pouch anal anastomosis (IPAA) in patients with ulcerative colitis or familial adenomatous polyposis and the mechanism is unknown. The dietary factors including dietary ingredients and mode are related to the occurrence and progression of pouchitis. Dietary factors may play a potential role in changing gut microbiome and regulating immune response. Therefore, adjusting the diet can prevent and treat pouchitis. This article reviews the research progress of the influence of dietary factors on pouchitis.
