This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Objective This study aimed to investigate the association between long-term radon exposure and changes in peripheral blood DNA methylation levels, as well as alterations in the expression of methylation-related regulatory genes (DNMT1, DNMT3A, and MBD2) among underground non-uranium metal miners. Methods Five non-uranium metal mines with varying levels of radon exposure were enrolled in this study. From each mine, 30 underground miners and 30 aboveground workers were randomly recruited. Basic demographic information was collected via a standardized questionnaire, and peripheral venous blood samples were obtained from all participants. An enzyme-linked immunosorbent assay (ELISA) colorimetric method was used to detect peripheral blood DNA methylation levels. Real-time quantitative PCR was used to measure mRNA expression levels of DNMT1, DNMT3A, and MBD2. These indicators were compared between underground and aboveground groups and among underground miners with different radon exposure levels. Multiple linear regression analysis was conducted to examine the associations between cumulative radon dose and two outcomes: peripheral blood DNA methylation levels, and the expression levels of methylation-related regulatory genes in underground miners. Results The average radon concentration in the underground workplaces of the five mines was 4,088 Bq/m³ (range: 116-18,188 Bq/m³), corresponding to an estimated annual effective dose of approximately 25.67 mSv for miners. The average radon concentration in aboveground workplaces was 58 Bq/m³ (range: 28-1796 Bq/m³), equivalent to an annual effective dose of approximately 0.51 mSv for aboveground workers. The average cumulative radon dose of underground miners was approximately 26.56 times that of aboveground workers (Z=−12.469, P<0.001). Compared with the aboveground workers, the peripheral blood DNA methylation level of underground miners was significantly decreased, approximately 0.77 times that of the aboveground group (Z=−2.313，P<0.05), accompanied by decreased expression of DNA methyltransferase genes DNMT1 and DNMT3A, which were 0.83 and 0.68 times those of the aboveground group, respectively (Z=−3.002、−4.190，P<0.01). After adjusting for age, working years, body mass index, smoking status, and alcohol consumption, multiple linear regression analysis revealed two key findings: cumulative radon dose was significantly and inversely correlated with peripheral blood DNA methylation levels (β=−0.752, P<0.001); and cumulative radon dose was significantly negatively associated with the expression of DNMT1 and DNMT3A (β=−0.319, −0.369, P<0.01). Conclusion The reduced DNA methylation levels and downregulated expression of DNA methyltransferase genes in underground miners are closely associated with long-term radon exposure.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

Objective: To evaluate the impact of comprehensive nursing based on the behavioral goal attainment model on the clinical intervention effect among elderly female patients with stress urinary incontinence (SUI), so as to provide a basis for optimizing the nursing strategies for patients with SUI and improving their quality of life. Methods: A total of 190 elderly female patients with SUI who were treated in the Department of Gynecology of the First Hospital of Jilin University from January 2023 to August 2024 were selected and randomly divided into the intervention group and the control group. The control group received routine nursing care, while the intervention group received comprehensive nursing based on the behavioral goal attainment model. The 1-hour pad test was used to assess urinary incontinence symptoms. The bio-electrical stimulation feedback instrument was employed to detect the electromyogram (EMG) values in the pre-resting stage and slow-muscle stage for evaluating pelvic floor function. The bladder function scale was utilized to evaluate bladder function. The Chinese version of urinary incontinence ego-efficacy rating scales and incontinence quality of life assessment scale (IQOL) were used to assess self-efficacy and quality of life. The data on intervention compliance and nursing satisfaction were collected by a questionnaire survey. The differences between the two groups before and after the intervention were compared using the analysis of variance for repeated-measures data to evaluate the intervention effect. Results: There were 95 cases in the control group and 95 cases in the intervention group, with median ages were 64.00 (interquartile range, 23.50) and 64.50 (interquartile range, 19.50) years, respectively. The proportion of patients with cesarean section as the last delivery method was 21.05% in the control group and 12.63% in the intervention group. The proportion of patients with moderate disease severity was 67.36% in the control group and 58.95% in the intervention group. There were no statistically significant differences in age, body mass index, number of pregnancies, number of deliveries, marital status, educational level, mode of last delivery and severity of the disease between the two groups of patients (all P>0.05). The analysis of variance of repeated-measures data showed that there were significant interactions between time and group for the urine leakage volume in the 1-hour pad test, the EMG values in the pre-resting stage, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, and the IQOL scores (all P<0.05). After 12 weeks of intervention, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, the IQOL scores in the intervention group were higher than those in the control group, while the urine leakage volume in the 1-hour pad test and the EMG values in the pre-resting stage in the intervention group were lower than those in the control group (all P<0.05). The good compliance rate of intervention and the satisfaction rate of nursing in the intervention group were higher than those in the control group (83.16% vs. 60.00%, 90.53% vs. 75.79%, both P<0.05). Conclusion Comprehensive nursing based on the behavioral goal attainment model can improve urinary incontinence symptoms, pelvic floor function, bladder function, self-efficacy, quality of life, and intervention compliance of elderly female patients with SUI.

Objective Jiedu Tongluo Tiaogan Formula(JTTF)is an effective formula for the clinical treatment of type 2 diabetes mellitus(T2DM).We used integrated pharmacology and in vitro experiments to explore the molecular mechanism of JTTF to improve insulin resistance(IR)in T2DM.Methods The drug targets of JTTF were obtained by identifying the key active ingredients of JTTF through UPLC-Q-TOF-MS.Multiple databases such as GeneCards,OMIM,and DrugBank were used to screen T2DM-IR related targets.Cytoscape software and String 11.0 database were used to construct the PPI network diagram of JTTF for T2DM-IR.GO and KEGG analyses were performed according to the Metascape platform to find the biological pathways related to the target proteins.AutoDock Tools software was used to simulate molecular docking.In vitro experiments were performed using palmitic acid(PA)-induced HepG2-IR cell model to detect the effect of JTTF on HepG2-IR.Results 28 effective active components of JTTF were screened.There were 857 gene targets of T2DM-IR,and 168 targets of drug-disease intersection.387 GO entries and 145 KEGG pathways were enriched.The molecular docking results showed that the main components of JTTF had good binding activities with PI3K and AKT-related proteins.The in vitro results showed that JTTF significantly alleviated PA-induced HepG2 cell injury,increased HepG2 glucose consumption,increased PI3K and AKT mRNA and protein expression,regulated the expression of GLUT2,GLUT4 and GSK3β,and improved cellular IR.Conclusion JTTF increases insulin sensitivity of HepG2-IR cells,promotes glucose uptake and intracellular glucose metabolism process,and its mechanism of action may be related to the up-regulation of PI3K/AKT signalling pathway.

Objective:To explore the relationship between drug literacy and quality of life in patients with multiple chronic diseases.Methods:It was a cross-sectional study. Between March and October 2023, 260 patients with multiple chronic diseases from the General Medicine Department of Peking University Third Hospital were selected using a convenience sampling method. A medication literacy scale, a medication adherence scale, and a health survey scale (SF-36 scale) were used to conduct a questionnaire survey in the patients. The SF-36 scale reflected the quality of life of the patients (including physical health and mental health). A total of 260 questionnaires were distributed, 260 questionnaires were returned, and 240 were effective (92.3%). Single-factor analysis of medication literacy in those patients was conducted using F-test and t-test. The correlation between medication literacy and medication adherence, as well as between medication literacy and quality of life, was analyzed using Pearson′s test. The correlation between different factors and medication adherence, as well as quality of life, in those patients was analyzed using multiple linear regression. Results:Among the 240 patients with multiple chronic diseases, 134 were male and 106 were female, aged (65.84±11.56) years. The drug literacy scale score was (8.36±3.57) points, the SF-36 physical health score was (242.00±87.85) points, mental health score was (275.67±80.29) points, medication compliance scale score was (6.22±1.93) points. The drug literacy was positively correlated with medication compliance ( r=0.157) and mental health ( r=0.165) in patients with multiple chronic diseases (all P<0.05). The score of drug literacy ( SE=2.440), mental health score ( SE=2.523), perceptual impairment ( SE=2.046) and duration of disease ( SE=2.459) were positively correlated with the medication compliance of the patients, while the number of chronic diseases ( SE=-2.818) was negatively correlated with the medication compliance of the patients (all P<0.05). The score of drug literacy ( SE=0.121) and insensible perception disorder ( SE=0.399) were positively correlated with the quality of life of the patients, and the number of chronic diseases ( SE=-0.171) was negatively correlated with the quality of life of the patients (all P<0.05). Conclusion:The drug literacy of patients with multiple chronic diseases is at the medium level, and the drug literacy is positively correlated with medication compliance and quality of life.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To investigate the impact of immobilization devices and treatment couches on the planned dose in stereotactic body radiation therapy(SBRT).Methods A retrospective study was conducted involving 23 SBRT patients,all of whom underwent CT simulation with foam padding or vacuum bag immobilization.For each patient,two sets of contours were outlined on CT images:one encompassing only the patient's skin(Body),and the other including the skin plus immobilization devices(BodyF).Initially,a reference plan(noFC)meeting clinical requirements was generated based on the Body contour.Without altering the plan(noFC)parameters and field setups,plan calculations were performed separately based on three different contours:BodyF(with immobi-lization devices only),Body+C(with treatment couch only),and BodyF+C(with both immobilization devices and treatment couch),yielding plan(F),plan(C),and plan(FC),respectively.By comparing the target and skin dose parameters across these four plans,the effects of immobilization devices and treatment couches on the planned dose were evaluated.Results Compared to plans based solely on the patient's skin contour,plans incorporating immobilization devices showed reduced high-dose,prescription dose coverage,and average dose in the target volume.Notably,the difference in the percentage of the planning target volume(PTV)receiving 105%of the prescribed dose(PTV/V105%p(%))between plan(FC)and plan(noFC)could reach 61.86%.Conversely,plans with immobilization devices increased both the maximum and average skin doses.Specifically,the dose to 10 cc of skin within 2 mm of the surface(body 2 mm/D 10 cc(Gy))showed a 21.36%difference between plan(FC)and plan(noFC).For all target and skin parameters,no statistically significant differences were observed between plan(C)and plan(noFC).Among plans with immobilization devices,the minimum distance from the target to the skin correlated inversely with skin dose,indicating greater impact on skin dose with closer proximity.Conclusions Immobilization devices in SBRT lead to beam attenuation and altered build-up effects,significantly reducing target dose parameters while increasing skin dose.The closer the target is to the skin,the greater the impact of immobiliza-tion devices on skin dose.It is recommended to incorporate immobilization devices into the contour design during radiotherapy planning.

Aim To investigate the antagonistic effect of Schizandrin A(SchA)on oxidative stress-induced endothelial dysfunction and its mechanism of action.Methods Human umbilical vein endothelial cells(HUVECs)were selected as the research subjects,and the effects of SchA on cell viability were detected by MTT assay;the content of ROS in the cells was detec-ted by flow cytometry;the content of MDA and CAT in the cells,and the content of NO and ET-1 in the cell supernatant were detected by kit assay;and the expres-sion of SOD1,p-eNOS/eNOS proteins,and ET-1 in the cell supernatant were detected by Western blot.Immu-nofluorescence experiments were performed to detect Nrf2 entry into the nucleus of cells.Results SchA re-versed the LPS-or hypoxia-induced increase in ROS and MDA content as well as the decrease in SOD1 and CAT content in HUVECs by activating the Nrf2/Keap1/HO-1 signaling pathway.SchA inhibited the decrease of p-eNOS and eNOS protein expression in HUVECs cells,as well as NO content in cell culture medium and the increase of ET-1 content induced by LPS.The Nrf2 inhibitor ML385 reversed the antagonis-tic effects of SchA on oxidative stress and endothelial dysfunction.Conclusions SchA antagonized LPS and hypoxia-induced oxidative stress,and SchA amelio-rated oxidative stress-induced endothelial dysfunction by up-regulating the Nrf2/Keap1/HO-1 signaling path-way.
