ObjectiveTo observe the effects of Danggui Shaoyaosan on macrophage polarization and renal inflammation in db/db mice with diabetic kidney disease (DKD), and to explore its renal protective effects and underlying mechanisms. MethodsEight db/m mice were assigned to the normal group, and forty db/db mice were randomly divided into a model group, low-, medium-, and high-dose Danggui Shaoyaosan groups (8.39, 16.77, 33.54 g·kg-1), and an irbesartan group (0.025 g·kg-1). All mice were administered treatment by gavage for 12 consecutive weeks. General conditions of the mice were observed during the intervention. At the end of the 12-week intervention, 24-h urine samples were collected using metabolic cages, after which the mice were anesthetized for sample collection. Blood was collected by enucleation and centrifuged to obtain serum for the determination of glycated serum protein (GSP), serum creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), and triglycerides (TG). The urinary albumin-to-creatinine ratio (UACR) was measured. Renal pathological changes were observed using hematoxylin-eosin (HE) staining, periodic acid-Schiff (PAS) staining, and Masson staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and monocyte chemoattractant protein-1 (MCP-1) levels. Immunofluorescence (IF) was performed to detect F4/80 expression in renal tissue, and immunohistochemistry (IHC) was used to assess CD206 expression. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to measure the mRNA expression of TNF-α, IL-10, inducible nitric oxide synthase (iNOS), and arginase-1 (Arg-1). Western blot analysis was used to detect the protein expression of iNOS, Arg-1, CD86, and CD206 in renal tissue. ResultsCompared with the normal group, the model group showed increased levels of GSP, UACR, SCr, BUN, TC, and TG, elevated levels of the inflammatory factor TNF-α and the chemokine MCP-1, and decreased IL-10 levels (P<0.01). Pathological examination revealed glomerular hypertrophy, mesangial cell proliferation with marked mesangial expansion, inflammatory cell infiltration, vacuolar degeneration of renal tubular epithelial cells, prominent glycogen deposition, and increased collagen fiber deposition. In addition, relative F4/80 fluorescence intensity was enhanced, CD206 expression in the glomeruli and renal interstitium was reduced, and TNF-α and iNOS mRNA expression was increased. IL-10 and Arg-1 mRNA expression was decreased, iNOS and CD86 protein expression was increased, and Arg-1 and CD206 protein expression was decreased (P<0.05, P<0.01). Compared with the model group, the Danggui Shaoyaosan groups and the irbesartan group showed decreased levels of GSP, UACR, SCr, BUN, TC, and TG, reduced serum TNF-α and MCP-1 levels, and increased IL-10 levels. Renal pathological damage was improved to varying degrees. Relative F4/80 fluorescence intensity was reduced, CD206 expression in the glomeruli and renal interstitium was increased, and TNF-α and iNOS mRNA expression was decreased. IL-10 and Arg-1 mRNA expression was increased, iNOS and CD86 protein expression was reduced, and Arg-1 and CD206 protein expression was increased (P<0.05, P<0.01). ConclusionDanggui Shaoyaosan can improve renal function and alleviate renal pathological damage in db/db mice. Its mechanism may be related to inhibiting M1 pro-inflammatory macrophage polarization, promoting M2 anti-inflammatory macrophage polarization, reducing inflammatory responses, delaying the progression of renal fibrosis, improving renal pathological injury, and thereby exerting renal protective effects.

To analyze the clinical and genetic features of oculopharyngodistal myopathy (OPDM) patients and compare the phenotypic differences among various causative genes. A total of 65 genetically confirmed OPDM patients from 43 unrelated families, who were admitted to the Department of Neurology, Peking University First Hospital between January 2008 and December 2025, were retrospectively included.The general demographic data, clinical manifestations, laboratory/auxiliary examinations, muscle pathology, and genetic test results were systematically collected and analyzed. The clinical and pathological characteristics among different OPDM subtypes were compared. Among the 65 patients(39 male and 26 female), the mean age of onset was (31.20±10.43) years (range: 14 to 63 years). The initial symptom was predominantly distal limb weakness (67.44%), which gradually progressed to involve the extraocular muscles, pharyngeal muscles, facial muscles and proximal limb muscles. Serum creatine kinase levels were mildly to moderately elevated. Muscle pathological examinations revealed rimmed vacuoles and intranuclear inclusions (within muscle fibers). The mean duration from onset to diagnosis was (12.33±7.88) years (range: 1 to 32 years). All probands had negative results on conventional next-generation whole-exome sequencing; pathogenic variants were identified through third-generation long-read sequencing or OPDM-targeted repeat-primed polymerase chain reaction(RP-PCR). Among the 43 families, OPDM2 subtype was the most common genetic subtype ( OPDM2 was the predominant subtype in this study. All subtypes share similar age of onset and muscular pathological changes, yet exhibit distinct disease progression patterns. Future multicenter prospective cohort studies are warranted to further elucidate the clinical characteristics, pathogenetic mechanisms, and prognostic differences among OPDM subtypes.

Based on the theoretical framework of "grease-turbidity-heat toxin", this paper elucidates the patholo-gical evolution pattern underlying the alternation between active and remission phases of inflammatory bowel disease (IBD). It is proposed that the active phase of IBD represents a progressive and explosive process characterized by internal accumulation of grease turbidity, constraint transforming into heat, and exuberant heat generating toxin. During the remission phase, the pathogenic process manifests as subsidence of heat toxin, depletion of qi and yin, latent retention of residual turbidity, and a state of coexistence between deficiency of healthy qi and lingering pathogenic factors. Accordingly, a staged therapeutic strategy with dynamic intervention and targeted modulation has been established. During the active phase, treatment follows the sequential principle of unblocking, clearing, and resolving pathogenic factors. In the early stage, the therapeutic approach focuses on regulating qi movement, fortifying the spleen, and resolving turbidity, using Tongxie Essential Formula (痛泻要方) and Shenling Baizhu Powder (参苓白术散) to regulate qi and fortify spleen. In the middle stage, the strategy emphasizes clearing heat, eliminating dampness, and dispersing pathogenic accumulation through downward and outward pathways, and Gegen Qinlian Decoction (葛根芩连汤) combined with Banxia Xiexin Decoction (半夏泻心汤) is used to clear and resolve damp-heat. In the late stage, treatment aims to resolve toxin, restrain sore, cool blood, and stabilize collaterals, using Baitouweng Decoction (白头翁汤), Shaoyao Decoction (芍药汤), and Xijiao Dihuang Decoction (犀角地黄汤) to eliminate toxins and cool blood. During the remission phase, the principle of reinforcing, consolidating, and penetrating is adopted to restore internal balance and clear the source, using Sishen Pills (四神丸) and Sijunzi Decoction (四君子汤) to reinforce healthy qi and venting pathogens.

Based on the theory of Zi Wu Liu Zhu (子午流注, the ebb and flow of midnight and midday) and the clinical characteristics of diarrhea-predominant irritable bowel syndrome (IBS-D) that its symptoms mainly occur during chou (丑) period (01:00—03:00), mao (卯) period (5:00—7:00), and si (巳) period (9:00—11:00), this paper proposes a temporal pathogenesis chain of "liver constraint during chou period, intestinal stagnation during mao period, and spleen deficiency during si period". Within this chain, liver constraint serves as the initiating factor, and intestinal stagnation manifests as the branch, while spleen deficiency constitutes the root of the disease. Accordingly, a chronotherapeutic principle of "soothing the liver, regulating the intestines, and fortifying the spleen" is proposed, establishing a corresponding time-based syndrome differentiation and treatment system. During chou period, the treatment should focus on soothing the liver to relieve constraint and calming the mind to tranquilize the spirit, thereby blocking the mechanism of liver constraint overacting on the spleen. During mao period, the focus is regulating qi to resolve dampness and harmonizing the intestine to alleviate the branch symptoms of morning abdominal pain and diarrhea. During si period, the suggested method is fortifying the spleen and supplementing qi to drain dampness and stop diarrhea, thereby restoring the pivot of spleen-stomach transportation and transformation. These methods are complemented by strategies to optimize medication compliance, thereby providing a new chronotherapeutic approach for clinical diagnosis and treatment of IBS-D.

Objective:To analyze the current status and related factors of occupational burnout among immunization program staff in Dezhou City in 2025.Methods:From February to March 2025, 1 209 healthcare workers engaged in immunization programs in all disease prevention and control centers (CDCs), vaccination clinics and obstetrics vaccination rooms within the jurisdiction of Dezhou City were enrolled in this study. Basic information was collected via questionnaires. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to assess occupational burnout status across three dimensions: emotional exhaustion, depersonalization and low personal achievement, with severity graded by scores. Multivariate logistic regression models were adopted to analyze the related factors of occupational burnout.Results:Among 1 209 participants, 986 (81.56%) were female and 513 (42.43%) were aged ≥40 years old. About 91 (7.53%) worked in CDCs, 970 (80.23%) in vaccination clinics and 148 (12.24%) in obstetric units. The detection rate of occupational burnout was 83.87% (1 014/1 209), with mild-to-moderate and severe occupational burnout rates of 16.38% (198/1 209) and 67.49% (816/1 209), respectively. Multivariate logistic regression model showed that compared with those who had no intention of resigning, those who frequently had turnover intention ( OR=10.225, 95% CI: 4.093-25.543) had a higher risk of experiencing occupational burnout. Compared with those who slept for more than seven hours a day, those who slept for less than six hours a day ( OR=4.266, 95% CI: 1.773-10.266) and those who slept for 6-7 hours ( OR=1.543, 95% CI: 1.100-2.164) had a higher risk of developing occupational burnout. Conclusion:The detection rate of occupational burnout among immunization program staff in Dezhou City is relatively high, significantly related to frequent turnover intention and insufficient sleep.

Objective:To investigate the association between blood selenium levels and sex hormones in Chinese men aged 18-79 years.Methods:Data were derived from the China National Human Biomonitoring survey conducted in 2017-2018, with a final sample size of 5 414 men. General demographic characteristics, behavioral habits, and dietary frequency were collected through questionnaires and physical examinations. Fasting blood samples were collected to measure blood lead, serum testosterone, and estradiol levels. Complex sampling linear regression models were used to analyze the associations between blood selenium levels and testosterone, estradiol, and the testosterone/estradiol ratio, adjusting for confounding factors including age, education level, marital status, smoking status, alcohol consumption, seafood intake, soy product intake, protein supplement intake, BMI, and diabetes status.Results:The mean age of the 5 414 participants was (46.85±27.91) years; 4 774 (91.65%) were of Han ethnicity and 4 505 (86.68%) were married. The median ( Q1, Q3) blood selenium concentration in men was 97.80 (80.64, 116.99) μg/L. After adjusting for confounding factors, the complex sampling linear regression model revealed negative associations between blood selenium levels and both testosterone levels and the testosterone/estradiol ratio, with a significant linear trend ( Ptrend<0.05). Compared with the Q1 group, the β (95% CI) values for testosterone in the Q2, Q3, and Q4 groups were -0.02 (-0.06 to 0.02), -0.03 (-0.08 to 0.01), and -0.06 (-0.09 to -0.02), respectively. Similarly, the β (95% CI) values for the testosterone/estradiol ratio in the Q2, Q3, and Q4 groups were -0.01 (-0.03 to 0.02), -0.01 (-0.04 to 0.04), and -0.03 (-0.06 to -0.01), respectively. Subgroup analysis indicated stronger associations between blood selenium levels and testosterone/estradiol levels in non-smoking and obese men (BMI≥28 kg/m2). Conclusion:Blood selenium levels are negatively associated with testosterone levels and the testosterone/estradiol ratio in Chinese adult males.

Objective:To explore the association of blood and urinary cadmium levels with lipid profile levels and dyslipidemia in Chinese adults aged 18 to 79 years.Methods:Based on the China National Human Biomonitoring (CNHBM) program, a cross-sectional survey was conducted from 2017 to 2018 using a multi-stage stratified random sampling method, including a total of 10 713 adults aged 18 to 79 years. Data was obtained through questionnaires, physical examinations, biological sample collection, and laboratory testing. Multiple linear mixed effect model (MLMM) and generalized linear mixed effect model (GLMM) were used to analyze the association of blood and creatinine-corrected urinary cadmium levels with lipid profile levels as well as dyslipidemia among adults.Results:The age of 10 713 participants was (47.23±0.24) years, with 5 372 males accounting for 61.3% of the national population. The weighted mean±standard error (SE) of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) was (5.21±0.03), (1.86±0.03), (2.96±0.03), and (1.43±0.01) mmol/L, respectively. The prevalence rate of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, low HDL-C, and high LDL-C was 16.0%, 21.6%, 6.6%, 13.5%, and 10.0%, respectively. MLMM showed that, after adjusting for relevant confounders, log-transformed blood cadmium levels were positively associated with increased levels of TC, TG and LDL-C ( P<0.05). When blood cadmium levels were categorized into quartiles, compared to the lowest exposure group ( Q1), participants in the highest blood cadmium exposure group ( Q4) had increases of 0.19 (95% CI: 0.06, 0.32) mmol/L in TC and 0.25 (95% CI: 0.08, 0.43) mmol/L in TG. GLMM indicated that, after adjusting for confounders, higher blood cadmium exposure levels were associated with increased risks of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and high LDL-C ( P<0.05). Further analysis by quartiles showed that, compared to the blood cadmium Q1 exposure group, the OR value (95% CI) for the Q4 group was 1.53 (1.12, 2.08) for hypercholesterolemia, 1.54 (1.09, 2.17) for hypertriglyceridemia, 2.24 (1.47, 3.40) for mixed hyperlipidemia, and 1.49 (1.07, 2.09) for high LDL-C. Conclusion:The cadmium internal exposure levels are associated with blood lipid profile levels as well as the incidence of dyslipidemia in Chinese adults aged 18 to 79.

Objective:To explore the mechanism of lncRNA FOXD2-AS1 regulating the expression of LATS1 via EZH2 to affect the proliferation and migration of clear cell renal cell carcinoma(ccRCC)cells.Methods:The GEPIA 2 online tool was used to analyze the expression levels of FOXD2-AS1 in ccRCC tissues from the Cancer Genome Atlas(TCGA)database,and their correlation with patients'overall survival rates was evaluated.Quantitative PCR(qPCR)was performed to analyze the expressions of FOXD2-AS1 in renal cancer cells and 26 clinically collected ccRCC tissue samples.CCK-8 cell proliferation assay and transwell chamber migration assay were employed to observe the effects of FOXD2-AS1 knockdown on the proliferation and migration of renal cancer cells.qPCR and Western blot analysis were utilized to assess the impact of FOXD2-AS1 knockdown on the expression of LATS1.RNA immunoprecipitation(RIP)and chromatin immunoprecipitation(ChIP)assays were performed to analyze the interaction between FOXD2-AS1,EZH2,and LATS1.Results:The GEPIA 2 software analysis revealed that FOXD2-AS1 was significantly upregulated in ccRCC tissues(P<0.01)and patients with high FOXD2-AS1 expression exhibited lower overall survival rates(P<0.05).The qPCR analysis results showed that FOXD2-AS1 was significantly upregulated in 26 samples of ccRCC tissues compared with adjacent normal kidney tissues(P<0.01).Compared with immortalized renal tubular epithelial cell line HK-2,the expression of FOXD2-AS1was significantly elevated in three types of renal cancer cell lines(786-O,ACHN and SN12-PM6)(P<0.01).Knockdown of FOXD2-AS1 expression significantly decreased the proliferation and migration abilities of renal cancer cells(P<0.05),and markedly increased the mRNA and protein expression levels of LATS1(all P<0.01).RIP and ChIP assays confirmed that FOXD2-AS1 can bind and recruit EZH2 to the promoter region of LATS1 to exert its effect.Salvage experiments demonstrated that knocking down LATS1 or overexpressing EZH2 partially reversed the inhibitory effect of FOXD2-AS1 knockdown on the proliferation and migration of renal cancer cells.Conclusion:FOXD2-AS1 is highly expressed in ccRCC,and it negatively regulates the expression of LATS1 by recruiting EZH2 to the promoter region of the LATS1 gene,thereby facilitating the proliferation and migration of renal cancer cells.
