Objective To observe the clinical efficacy of traditional Chinese medicine(TCM)sequential therapy in treating patients with psoriasis vulgaris in Shenzhen,and to explore the syndrome differentiation and treatment for the patients with psoriasis vulgaris in Shenzhen region.Methods From January 2019 to February 2024,70 cases of psoriasis vulgaris admitted to Shenzhen Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Shenzhen Bao'an Traditional Chinese Medicine Hospital Group)were retrospectively analyzed.The patients were divided into the observation group(39 cases)and the control group(31 cases)according to the treatment plans.In the control group,only topical application of Calcipotriol Ointment was given throughout the treatment,while in the observation group the patients were treated with TCM sequential therapy according to the illness stage on the basis of treatment for the control group,i.e.,internal administration of modified Shuiniujiao Huanglian Decoction was given in the acute stage and modified Sijunzi Shuiniujiao Decoction was given in the remission stage.Both groups were treated for 3 months.Before and after the treatment,the changes of Psoriasis Area and Severity Index(PASI)scores,Dermatology Life Quality Index(DLQI)scores and TCM syndrome scores in the two groups were observed.After treatment,the clinical efficacy and drug safety of the two groups were evaluated.Results(1)After 3 months of treatment,the total effective rate of the observation group was 89.74%(35/39),and that of the control group was 74.19%(23/31).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the PASI scores for evaluating the severity of skin lesions in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the DLQI scores for evaluating the quality of life in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the scores of TCM syndromes such as erythema,itching,vexation and dry mouth in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment period,no obvious adverse reactions occurred in the two groups of patients,with high safety.Conclusion On the basis of conventional western medicine treatment,application of TCM sequential therapy exerts certain clinical efficacy in treating patients with psoriasis vulgaris in Shenzhen region,and the combined therapy is effective on controlling the patients'illness conditions,significantly alleviating the symptoms and improving the quality of life of the patients.

This study was performed to investigate the inhibitory effects of Xuebijing injection(XBJ)on lipopolysaccharide(LPS)-induced inflammatory signals on EA.hy926 vascular endothelial cells and the underlying mechanism,and to provide a theoretical basis for the treatment of sepsis with XBJ.WST-1 assay was used to detect the effects of XBJ on the cell viability;Western blot analysis was performed to detect the protein expression levels of IκBα,p-p65,p-ERK,p-JNK,p-p38,p-AMAD17 in cell lysates and the content of sTLR4 fragment in the concentrated culture supernatants.ADAM17 sheddase activity in cells was detected by using a commercial available kit.Data showed that all of the TLR4-mediated inflammatory signals were significantly inhibited by the treatment of XBJ(P＜0.01).ADAM17 phosphorylation and shedding activity were induced by XBJ treatment,simultaneously the sTLR4 contents in the culture media were increased.XBJ-induced shedding of TLR4 was suppressed by the preteatment of 10 μmol/L TAPI-1(an ADAM17 inhibitor).Taken together,XBJ can induce the shedding of TLR4 from cell membrane by up-regulating ADAM17 shedding activity,thereby inhibiting the activation of TLR4-mediated intracellular inflammatory signals in EA.hy926 cells.

Objective:To evaluate the role of autophagy in hydrogen-rich solution-induced reduction of remifentanil-induced hyperalgesia in rats.Methods:Thirty-two clean-grade healthy male Sprague-Dawley rats, aged 2-3 months, weighing 240-260 g, were divided into 4 groups ( n=8 each) by a random number table method: incisional pain group (group I), remifentanil+ incisional pain group (group RI), hydrogen-rich solution+ remifentanil+ incisional pain group (group HRI), and hydrogen-rich solution + autophagy inhibitor+ remifentanil+ incisional pain group (MHRI group). The tail vein was catheterized, the equal volume of normal saline was intravenously infused for 60 min while the incisional pain model was developed in group I, and remifentanil was intravenously infused at a rate of 1 μg·kg -1·min -1 for 60 min while the incisional pain model was developed in RI, HRI and MHRI groups, hydrogen-rich solution 10 ml/kg was intraperitoneally injected at 10 min before preparing the model in group HRI, and 3-MA 15 mg/kg was intraperitoneally injected at 1 h before preparing the model in MHRI group, and the other treatments were similar to those previously described in group HRI. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were determined at 24 h before and 2, 6, 24 and 48 h after the end of infusion. The rats were sacrificed under anesthesia after the behavioral testing, and the lumbar enlargement segment of the spinal cord was removed for determination of the expression of microtubule-associated protein 1 light chain 3Ⅱ (LC3Ⅱ), Beclin-1 and P62 by Western blot. Results:Compared with the baseline at T 0, the MWT was significantly decreased and TWL was shortened at T 1-4 in the four groups ( P<0.05). Compared with group I, the MWT was significantly decreased and TWL was shortened at T 1-4, the expression of LC3 II and Beclin-1 was up-regulated, and the expression of P62 was down-regulated in group RI and group HRI ( P<0.05). Compared with group RI, the MWT was significantly increased and TWL was prolonged at T 1-4 in group HRI and group MHRI, the expression of LC3 II and Beclin-1 was significantly up-regulated, and the expression of P62 was down-regulated in group HRI, and the expression of LC3 II and Beclin-1 was significantly down-regulated, and the expression of P62 was up-regulated in group MHRI ( P<0.05). Compared with group HRI, the MWT was significantly decreased and TWL was shortened at T 1-4, the expression of LC3 II and Beclin-1 was down-regulated, and the expression of P62 was up-regulated in group MHRI ( P<0.05). Conclusions:The mechanism by which hydrogen-rich solution alleviates hyperalgesia may be related to enhancing the level of autophagy in the spinal cord of rats with incisional pain induced by remifentanil.

Several mitochondrial dysfunctions in obesity and diabetes include impaired mitochondrial membrane potential, excessive mitochondrial reactive oxygen species generation, reduced mitochondrial DNA, increased mitochondrial Ca2+ flux, and mitochondrial dynamics disorders. Mitophagy, specialized autophagy, is responsible for clearing dysfunctional mitochondria in physiological and pathological conditions. As a paradox, inhibition and activation of mitophagy have been observed in obesity and diabetes-related heart disorders, with both exerting bidirectional effects. Suppressed mitophagy is beneficial to mitochondrial homeostasis, also known as benign mitophagy. On the contrary, in most cases, excessive mitophagy is harmful to dysfunctional mitochondria elimination and thus is defined as detrimental mitophagy. In obesity and diabetes, two classical pathways appear to regulate mitophagy, including PTEN-induced putative kinase 1 (PINK1)/Parkin-dependent mitophagy and receptors/adapters-dependent mitophagy. After the pharmacologic interventions of mitophagy, mitochondrial morphology and function have been restored, and cell viability has been further improved. Herein, we summarize the mitochondrial dysfunction and mitophagy alterations in obesity and diabetes, as well as the underlying upstream mechanisms, in order to provide novel therapeutic strategies for the obesity and diabetes-related heart disorders.

Objective:To explore the teaching effect and novel ideas of online teaching applied in skill operation course.Methods:One hundred and fifty-one students studying in Sichuan University taking the First Aid in the Life: Basic Knowledge and Skills as an elective course in the autumn semester of 2019 and spring semester of 2020 were included as the research subjects in this study. Among them, 77 students in the spring semester of 2020 were selected as the experimental group and 74 students in the autumn semester of 2019 were selected as the control group. The students in the experimental group studied the first aid course by online platform, and the others in the control group studied through traditional teaching mode. The teaching effect of the two groups was compared and the teaching satisfaction of the two groups weas analyzed. SPSS 23.0 was used for Chi-square test and t-test. Results:There was no significant difference between the control group and the experimental group in the assessment scores of cardiopulmonary resuscitation, hemostatic bandaging, and fracture fixation [(8.65±0.81 vs 8.69±0.90, P=0.750); (8.10±0.50 vs 8.12±0.61, P=0.880); (8.21±0.89 vs 8.16±0.78, P=0.710)]. Among the students participating in the questionnaire survey in the experimental group, 59 (95.16%) students thought that this course was helpful in dealing with first aid in daily life, and 38 (61.29%) students did not want to change the traditional teaching method to online teaching. Conclusion:The application of online teaching in first-aid skill operation course is feasible and can achieve the similar teaching effect, which provides a novel idea for exploring the online teaching of first aid skills.

Objective:To explore supportive care needs of patients with stable stroke in the acute phase and provide guidance for effective supportive care through mixed-methods.Methods:A mixed-method study with convergent parallel design was used. A convenient sampling method was used to select neurological inpatients for questionnaire survey. At the same time, a purposive sampling was used to conduct semi-structured interviews with 15 stroke patients.Results:A total of 176 valid questionnaires were collected, and the average score of supportive care needs were 2.17±0.37, The top 3 were disease-related information needs (2.75 ± 0.40), daily life care needs (2.28 ± 0.51), and social support needs (2.26 ± 0.28). Knowing the causes of stroke ranked first in each entry. The theme of qualitative interviews included: assisting daily activities, management of impaired functions, early functional rehabilitation, disease-related knowledge, psychosocial support, and discharge guidance.Conclusions:Stroke patients have rich and high-level supportive care needs, and provide corresponding information needs based on patient needs. Implement early secondary prevention guidance to prevent stroke recurrence; cooperate with multidisciplinary teams to provide early rehabilitation, reduce functional impairment; timely identify negative emotions of patients, and jointly provide family with patients psychological support. Implement a case management model to promote full-course care for stroke patients.

Objective:To investigate whether autophagy in the inflammatory environment of thrombotic antiphospholipid syndrome (APS) drives polymorphonuclear neutrophils (PMNs) to release neutrophil extracellular traps (NETs) and whether IFN-λ1(IL-29) has a function of inhibiting NETs-related thrombin production.Methods:PMNs isolated from peripheral blood of healthy volunteers were in vitro stimulated by serum samples of patients with active APS. IL-29 and 3-methyladenine (3-MA) were used to regulate NETs release and autophagy. NETs expression was evaluated by immunofluorescence technique (IFT) and flow cytometry (FCM). Autophagy-related proteins were detected by Western blot. The levels of thrombin-antithrombin (TAT) complexes were determined by enzyme-linked immunosorbent assay (ELISA). Results:The percentages of NETs released from PMNs of healthy volunteers after stimulation with serum samples of APS patients were (22.8±3.1)% according to IFT and (10.1±2.7)% according to FCM and used as control group. IL-29 and 3-MA inhibited the release of NETs from PMNs stimulated by serum samples of APS patients and the percentages of NETs were (5.3±2.2)% and (4.9±2.4)% detected by IFT, and (2.1±1.3)% and (2.7±1.4)% by FCM, respectively. There were significant differences with the control group ( q=9.89, 10.67, 11.74, 9.61, all P<0.01). IL-29 inhibited the expression of LC3B, but promoted the expression of p62 on PMNs of healthy volunteers after stimulating with serum samples of APS patients, and the differences with the group without IL-29 pretreatment were statistically significant [LC3B/GAPDH: (0.28±0.03)% vs (0.77±0.06)%, q=8.65; p62/GAPDH: (0.63±0.05)% vs (0.33±0.03)%, q=4.78; both P<0.01]. IL-29 and 3-MA reduced the levels of NETs-related TAT complexes from (7.6±0.6) ng/ml to (3.1±0.5) ng/ml and (4.7±0.4) ng/ml, respectively ( q=6.34 and 5.15, both P<0.01). Conclusions:Autophagy was involved in the formation of NETs and subsequent coagulation cascade activation in PMNs of healthy subjects after stimulation with serum samples of APS patients with thrombosis. IL-29 suppressed the production of NETs and NETs-associated thrombin by inhibiting autophagy.
