Oxidative stress can activate multiple inflammatory pathways， triggering and exacerbating psoriasis lesions. In traditional Chinese medicine （TCM）， blood turbidity refers to a pathological condition in which harmful stimuli or unhealthy lifestyle habits lead to an accumulation of impurities in the blood， resulting in increased viscosity and impaired circulation. Based on the correlation between blood turbidity theory in TCM and the pathological changes of oxidative stress in modern medicine， this paper explored the TCM diagnosis and treatment of psoriasis， proposing that spleen deficiency with latent turbidity is the fundamental cause of the disease. The pathological progression of psoriasis was outlined as follows， spleen deficiency with latent turbidity→phlegm and blood stasis intertwining→internal generation of toxic pathogens. Targeting oxidative stress， the study suggests syndrome differentiation and treatment with angle medicine （角药， means three medicinals combination）. The treatment strategy divided into three stages. For early stage， strengthening the spleen and directing the turbid downward， emphasizing prevention before onset， with angle medicine of Huangqi （Astragali Radix） - Fuling （Poria） - Baizhu （Atractylodis macrocephalae rhizoma） to treat； for middle stage， resolving phlegm and dispersing blood stasis， preventing disease progression， if patient with more phlegm syndrome treated with angle medicine of Banxia （Pinelliae rhizoma） - Chenpi （Citri reticulatae pericarpium） - Zhexie （Alismatis rhizoma）， and if patient with more stasis syndrome treated with Zicao （Arnebiae Radix） - Jixueteng （Spatholobi caulis） - Shouwuteng （Polygonum multiflorum Thunb）； for late stage， resolving toxins and dispelling pathogens， balancing both attack and supplementation， with Quanxie （Scorpio） - Tufuling （Smilacis glabrae rhizoma） - Shudihuang （Rehmanniae radix praeparata） to treat.

ObjectiveTo observe the efficacy and safety of Uyghur medicine Yangxin Dawayimixike Honey Paste （养心达瓦依米西克蜜膏， YDMHP） in the treatment of stable angina pectoris （SAP） of qi stagnation and blood stasis syndrome. MethodsA randomized ， double-blind， positive-controlled，multi-center clinical trial was conducted， in which 370 patients with SAP of qi stagnation and blood stasis syndrome were randomly divided into treatment group（279 cases）and control group（91cases）at a ratio of 3∶1. The treatment group was orally administered with YDMHP， 3 g each time， and placebo of Xuefu Zhuyu Capsule （血府逐瘀胶囊）， 2.4 g each time， while the control group was treated with Xuefu Zhuyu Capsule， 2.4 g each time， and placebo of YDMHP， 3 g each time， both twice a day for a course of 12 weeks. The primary outcome was the effect of angina pectoris symptom. The secondary outcomes include single angina symptom scores such as number of attacks， duration of attacks， pain intensity and usae of nitroglycerin scores， the total angina symptom score before and after the treatment， the usage of nitroglycerin， the exercise duration in treadmill exercise test （TET） and the Duck treadmill score among patients，the scores of Seattle Angina Questionnaire （SAQ） on five dimensions including physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception， and efficacy of TCM syndrome and of each single TCM symptom after treatment. The safety were evaluated by examine blood routine， urine routine， liver and kidney function， fasting blood sugar， electrocardiogram， adverse events. ResultsThe total effective rate of angina symptom in the treatment group was 71.69% （200/279）， significantly higher than 51.64% （47/91） in the control group （P＜0.01）. The curative and markedly effective rate of TCM syndrome in the treatment group was 53.05% （148/279）， which was significantly higher than 25.27% （23/91） in the control group （P＜0.01）. After treatment， scores of the number as well as duration of angina attacks and pain severity， the total score of angina symptoms， and the usage of nitroglycerin significantly decreased in both groups， and more changes were seen in the treatment group than in the control group； the scores of physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception in both groups significantly increased， and more improvement were shown in the experimental group regarding the anginal stability， anginal frequency and treatment satisfaction （P＜0.05 or P＜0.01）. The effects of chest pain， chest tightness， palpitation， shortness of breath and fatigue in experimental group were significantly higher than those in control group （P＜0.05 or P＜0.01）. There was no significant difference in the exercise duration of treadmill test and Duke score among patients between the two groups either before or after treatment （P＞0.05）. Adverse events occurred in 66 cases （23.66%） of the experimental group and 16 cases （17.58%） of the control group， with no statistical significance between the two groups （P＞0.05）. ConclusionThe Uyghur medicine YDMHP can effectively improve symptoms of angina pectoris， reduce the number， duration， and intensity of attacks， decrease the dosage of nitrogly-cerin and improve the individual TCM symptoms and has good safety in the treatment of SAP patients of qi stagnation and blood stasis.

Objective To analyze the changes of immune indicators in patients with systemic lupus erythematosus(SLE)and explore their correlation with lupus nephritis(LN).Methods A total of 109 SLE patients treated in Affiliated Lihuili Hospital of Ningbo University from November 2021 to October 2023 were retrospectively included in SLE group,SLE patients were divided into LN group(56 cases)and non-LN group(53 cases)according to whether they were diagnosed with LN or not.32 healthy people who underwent physical examination in the hospital during the same period were included in healthy control group.The immune indicators of subjects were detected,and the clinical data and the scores of systemic lupus erythematosus disease activity index 2000(SLEDAI-2000)were collected.Spearman correlation method was used to analyze correlation between SLEDAI-2000 scores and immune indicators in SLE patients.Multivariate Logistic regression was used to analyze the influencing factors of LN in SLE patients.Results The total lymphocyte count,T cell count,natural killer(NK)cell count,B cell count,helper T(Th)cell proportion,NK cell proportion,B cell proportion,immunoglobulin(Ig)M,complement C3 and complement C4 in SLE group were significantly lower than those in healthy control group(P<0.05),T cell proportion,suppressor T(Ts)cell proportion and anti-double-stranded DNA antibody IgG were significantly higher than those in healthy control group(P<0.05).SLEDAI-2000 scores in SLE group were negatively correlated with NK cell count,B cell count and NK cell proportion(P<0.05),and were positively correlated with T cell proportion and Ts cell proportion(P<0.05).The NK cell count,B cell count,NK cell proportion and B cell proportion in LN group were significantly lower than those in non-LN group(P<0.05),T cell proportion,anti-double-stranded DNA antibody IgG and SLEDAI-2000 scores were significantly higher than those in non-LN group(P<0.05).Multivariate Logistic regression analysis showed that NK cell count and SLEDAI-2000 scores were all factors influencing the development of LN in SLE patients(P<0.05).Conclusion Immune indicators have the ability to evaluate the disease status of SLE patients.SLE patients with decreased NK cell count and increased SLEDAI-2000 scores are more likely to develop LN.

Objective:To investigate the effect and regulation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) on islets function and NOD-like receptor family, pyrin domain containing 3 (NLRP3) and autophagy in type 2 diabetic mellitus (T2DM) mice.Methods:Experimental study. Twenty, 8-week-old, male C57BL/6J mice were selected and divided into a normal control group ( n=5) and a high-fat feeding modeling group ( n=15). The model of T2DM was established by high-fat feeding combined with intraperitoneal injection of low-dose streptozotocin. After successful modeling, those mice were divided into a diabetes group ( n=7) and a UC-MSCs treatment group ( n=7). The UC-MSCs treatment group was given UC-MSCs (1×10 6/0.2 ml phosphate buffer solution) by tail vein infusion once a week for a total of 4 weeks; the diabetes group was injected with the same amount of normal saline, and the normal control group was not treated. One week after the treatment, mice underwent intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests, and then the mice were sacrificed to obtain pancreatic tissue to detect the expressions of interleukin-1β (IL-1β) and pancreatic and duodenal homeobox 1 (PDX-1) by immunofluorescence. The bone marrow-derived macrophages were stimulated with lipopolysaccharide and adenosine triphosphate (experimental group) in vitro, then co-cultured with UC-MSCs for 24 h (treatment group). After the culture, enzyme-linked immunosorbent assay was used to detect the secretion level of IL-1β in the supernatant, and immunofluorescence staining was used to detect the expression of NLRP3 inflammasome, and related autophagy proteins. Statistical analysis was performed using unpaired one-way analysis of variance, repeated measure analysis of variance. Results:In vivo experiments showed that compared with the diabetes group, the UC-MSCs treatment group partially repaired islet structure, improved glucose tolerance and insulin sensitivity (all P<0.05), and the expression of PDX-1 increased and IL-1β decreased in islets under confocal microscopy. In vitro experiments showed that compared with the experimental group, the level of IL-1β secreted by macrophages in the treatment group was decreased [(85.9±74.6) pg/ml vs. (883.4±446.2) pg/ml, P=0.001], the expression of NLRP3 inflammasome and autophagy-related protein P62 was decreased, and the expressions of microtubule-associated protein 1 light chain 3β (LC3) and autophagy effector Beclin-1 were increased under confocal microscopy. Conclusions:UC-MSCs can reduce the level of pancreatic inflammation in T2DM mice, preserving pancreatic function. This might be associated with the ability of UC-MSCs to inhibit the activity of NLRP3 inflammasomes in macrophages and enhance autophagy levels.

Objective:To explore the characteristics of myopia nursing science popularization video of TikTok and its content, evaluate the quality of video content, so as to provide reference for nursing health education decision-makers.Methods:In March 2022, videos were screened and basic information was captured using the TikTok default "comprehensive retrieval" strategy with "myopia" as the keyword. Finally, 165 videos were included. According to the certification and introduction description of the video author, the video was divided into 3 sources, including medical staff, individuals or profit organizations, news or non-profit organizations. The DISCERN instrument was used to rate video credibility, diagnosis and treatment information quality, and overall quality. The video content coverage was rated from 6 aspects, involving definition, symptoms, risk factors, assessment, nursing, and outcome of myopia.Results:The median duration of 165 included videos was 60 seconds. Within the median release time of 217 days, a total of 801 854 likes and 130 474 shares were received. The video source was mainly medical and nursing staff (48.5%, 80/165). The total score of DISCERN was (37.1±7.5). The overall quality score of the video was 3.0 (2.0, 4.0), the credibility and diagnosis and treatment information quality scores were (19.4±3.9) and (16.9±4.2), respectively. The differences in DICERN (credibility, diagnosis and treatment information quality, and overall quality) scores among different video sources were statistically significant ( P<0.05). The video content focused on myopia management (72.7%, 120/165) and outcomes (65.5%, 108/165). The content scores of different video sources varied, with news or non-profit organization videos scoring higher than medical and nursing staff and individuals or profit organizations [ (5.92±2.51), (4.37±1.64), (5.02±2.24), respectively], with statistical differences ( P<0.05) . Conclusions:TikTok spreads information quickly, has a wide audience, and has great potential for nursing science popularization. However, the quality of nursing science popularization videos for myopia is medium to low, and the content covered is biased. There is an urgent need to create high-quality science popularization videos for myopia nursing.

Objective:To explore the application value of ultrasonic layer-specific strain technology in evaluating left ventricular systolic function in young male strength athletes.Methods:In October 2018, 30 professional young male wrestlers from Henan Provincial Heavy Sports Management Center (athlete group) and 30 healthy young males matched with age (control group) were randomly selected.Using traditional echocardiography combined with stratified strain technique, heart rate (HR), left ventricular end-diastolic diameter(LVDd), interventricular septal thickness on diastole(IVSTd), postwall thickness on diastole (PWTd), relative wall thickness (RWT), end diastolic volume index(EDVI), end systolic volume index (ESVI), ejection fraction (LVEF), stroke volume index (SVI), cardiac index (CI), spherical index (SPI), endocardial myocardial global longitudinal strain(GLSendo), mid-myocardial global longitudinal strain(GLSmid), epicardial myocardial global longitudinal strain(GLSepi), peak strain dispersion(PSD) and whole myocardial longitudinal strain cross-wall difference (ΔLS) were measured respectively. The differences between the two sets of data were analyzed.ROC curves were plotted to analyze and compare the stratified strain parameters performance to predict left ventricular systolic function or synchrony in athletes.Results:The values of LVDd, PWTd, IVSTd, RWT, SPI, EDVI, ESVI and SVI in athelete group were higher than those of the control group. And the values of HR, GLSendo, GLSmid, GLSepi and ΔLS were lower than those of the control group.The differences were statistically significant (all P<0.05). There was no significant difference in LVEF, CI and PSD between the two groups (all P>0.05). The areas under the ROC curve of GLSendo, GLSmid and GLSepi for athletes′ left ventricular systolic function were 0.753, 0.747 and 0.726, respectively, and the optimal cut-off values were -22.34%, -19.95%, -17.35%, respectively. Conclusions:Long-term high-intensity exercise can lead to subclinical changes in left ventricular systolic function, and ultrasonic layer-specific strain technology can more accurately and specifically evaluate left ventricular systolic dysfunction. Among the GLS parameters, GLSendo is the optimal parameter for testing the left ventricular systolic function of athletes.

Objective To investigate the effect of subclinical epileptiform discharges (SED) on the cognition of adult patients with epilepsy,exploring the mechanism of SED that leads to cognitive impairment in adult patients with epilepsy to raise physicians' attention about SED.Methods Patients were collected in the Department of Neurology,China-Japan Union Hospital of Jilin University from March 2016 to March 2017.Sixty adult patients with epilepsy without clinical episodes in the last three months were selected as SED group and 40 healthy volunteers as control group.Medical history of the SED group was recorded in detail.All patients were examined by Self-rating Anxiety Scale,Self-rating Depression Scale,Pittsburgh Sleep Quality Index scale in order to exclude organic brain disorders,metabolic diseases,anxiety,depression,sleep disorders and drug-induced cognitive dysfunction.Subjects in the two groups received Montreal Cognitive Assessment (MoCA),electroencephalogram and blood oxygen level dependent functional magnetic resonance imaging examination.Finally,the results were compared between the two groups.Results ①SED had different effects on cognitive function in adult patients with epilepsy,and the MoCA score (26(22,27)) showed statistically significant difference compared with the control group (29 (28,29),Z =-6.26,P =0.00).②Different discharges indexes showed different effects on cognitive function aspects.Cognitive impairment was significant when the discharges indexes were ＞ 10％ (discharges indexes 1％-10％:MoCA score 26(26,28),discharges indexes 10％-50％:MoCA score 22(19.5,25),Z =-4.74,P =0.00).③The cognitive function of epilepsy patients was positively correlated with the duration of education (r =0.41,P =0.00) and the time interval to recent seizure (r =0.31,P =0.02),and negatively correlated with SED (r =-0.57,P=0.17).There was no correlation between cognitive function and duration of disease and onset age.The SED was the main influencing factor of cognitive function in epilepsy.④Compared with healthy people,epilepsy patients with SED showed differences in resting brain function network connection,with strong connective regions at the right inferior temporal gyrus,right hippocampus,bilateral thalamus,with weak connective regions at the double medial upper frontal gyrus,lateral dorsal frontal gyurs.Conclusions SED had an effect on the cognitive function of adult patients with epilepsy.The mechanism of cognitive impairment in adult epilepsy with SED may be related to abnormal brain function in cognitive-related areas.

Objective To study the effect of infrasound on expression of calmodulin-dependent protein kinase II (CaMKII) and tau pro-tein in hippocampus of rats. Methods Fifty-six male Sprague-Dawley rats were randomized into control group (n=8), 1-day group (n=8), 7-day group (n=8) and 14-day group (n=32), and the 14-day group was subgrouped as 1-hour, 6-hour, 24-hour, 48-hour subgroups, naming after the time after infrasound exposure, 8 in each subgroup. All the test groups were put in an infrasound field with 8 Hz, 130 dB for 2 hours daily, while the control group was put in the infrasound instrument without infrasound exposure for 2 hours daily. The expression of pT286-CaMKII and tau protein in hippocampus was detected with immunohistochemisty, Western blotting and enzyme-linked immunoabsor-bent assay. Results The expression of pT286-CaMKII was the most in 14-day group (F>14.912, P<0.001), as well as the expression of tau pro-tein (F>36.229, P<0.001), and secondary in 7-day group (P<0.05). For 14-day group, the expression of tau protein was the most in 1-hour and 6-hour subgroups, and dropped down in 24-hour subgroup, although more than that in the control group (P<0.05). Conclusion Exposure of 8 Hz, 130 dB infrasound may induce phosphorylation of CaMKII and tau protein, and the expression of tau protein in hippocampal cells in rat, which may disturb their learning and memory function.
