ObjectiveTo investigate the mechanism by which Gegen Qinliantang(GQT) improves skeletal muscle insulin resistance. MethodsThe db/m mice were used as the normal group, while db/db mice were assigned to a model group, low-dose (3.12 g·kg-1), medium-dose (6.24 g·kg-1), and high-dose (12.48 g·kg-1) GQT groups, and a Western medicine group (semaglutide, 0.045 mg·kg-1),n=6 in each group. All groups received corresponding interventions. Intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), and hematoxylin-eosin (HE) staining were used to evaluate insulin resistance and therapeutic efficacy. Serum lipid levels were measured using an automatic biochemical analyzer, and apoptosis in skeletal muscle was assessed via TUNEL assay. Transcriptome sequencing combined with gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses was performed to identify differentially expressed genes (DEGs). Real-time quantitative polymerase chain reaction (Real-time PCR) was used to validate gene expression. Molecular docking was applied to evaluate the binding patterns between active components of GQT and key regulatory genes to elucidate pharmacological mechanisms. ResultsCompared with the model group, the medium-dose and high-dose GQT groups showed significantly reduced fasting blood glucose (FBG) levels (P<0.01). Triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were markedly decreased (P<0.01), while high-density lipoprotein cholesterol (HDL-C) was significantly increased (P<0.01). IPGTT, IPITT, and HE staining demonstrated that GQT enhanced insulin sensitivity and restored skeletal muscle morphology. GQT also alleviated apoptosis in skeletal muscle tissue. Transcriptome analysis revealed that GQT primarily affected biological processes such as oxidative phosphorylation, metabolic pathways, cellular processes, and protein binding. Real-time PCR results showed that CBR2, CDK6, F830016B08Rik, IL-1β, Rab27b, and COLEC12 were key regulatory genes. Molecular docking demonstrated that CBR2, IL-1β, Rab27b, and COLEC12 formed stable binding with the main active components of GQT. The therapeutic effects of high- and medium-dose GQT were comparable to those of the semaglutide group. ConclusionGQT improves skeletal muscle insulin resistance, potentially by regulating apoptosis as part of its underlying biological mechanism.

Intravascular large B-cell lymphoma(IVLBCL) is a rare and aggressive type of lymphoma with diverse and nonspecific clinical manifestations, often leading to misdiagnosis. This article reports a case of IVLBCL in a middle-aged male patient who initially presented with pulmonary arterial hypertension(PAH). The patient exhibited progressive hypoxemia and PAH, showing poor response to standard PAH therapy. Laboratory tests indicated a hyperinflammatory state and significantly elevated lactate dehydrogenase levels, while imaging revealed diffuse bilateral lung lesions. Random skin biopsy identified atypical B lymphocytes within subcutaneous capillaries, confirming the diagnosis of IVLBCL. Following treatment with the ZR-CHOP regimen, the patient's symptoms and laboratory parameters improved markedly. By reviewing relevant literature, this article systematically outlines the diagnostic and therapeutic process of this case, aiming to provide insights for the clinical recognition of such rare presentations.

Objective: To establish an accurate and rapid typing method for Rh typing of samples from patients who have received recent blood transfusions by utilizing the difference in osmotic fragility between fresh and old red blood cells. Methods: A lysing solution suitable for destroying old RBCs was prepared. Sixty-one samples collected in our hospital in 2024 with Rh typing of double groups were treated with the lysing solution to remove the old allogeneic red blood cells while preserving the patient's own fresh red blood cells, followed by repeat Rh typing tests. Results: For 61 samples with Rh typing in double groups, 41 were accurately detected identified through the red blood cell lysis method, yielding an identification rate of 67.21%. No significant difference was observed compared to the detection rate of the commonly used capillary centrifugation modified method (χ
=0.103, P>0.05). Conclusion: The red blood cell lysis method provides a novel and rapid experimental approach for clinical use in processing Rh-typed samples that are of double groups, thereby offering a basis for Rh compatibility blood transfusion.

Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ2= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ2= 108 186.1, P < 0.05) and 2020-2022 (χ2= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

Objective To explore the efficacy and safety of oral solution of magnesium sodium potassium sulfate in bowel preparation before colonoscopy. Methods Patients who planned to undergo colonoscopy at the digestive department of the Ninth People’s Hospital, affiliated to School of Medicine of Shanghai Jiao Tong University from January 2023 to August 2023 were selected and eligible subjects were divided into two groups: Group A took polyethylene glycol (PEG) and Group B took oral solution of magnesium sodium potassium sulfate (OSS). The quality, drug tolerance, and safety of intestinal preparation were evaluated. The quality of bowel preparation was evaluated by the boston bowel preparation scale (BBPS). Results The right colon BBPS score of Group B was (2.39±0.82) points, which was significantly higher than of Group A (2.11±0.43) points (P<0.05). The overall score of Group B was higher than that of Group A (P<0.05). OSS was easier to take than PEG, with a good taste and overall sensation. Patients were willing to use OSS to clean their bowels even when they were willing to undergo another examination (P<0.05). There was a significant difference in nausea and vomiting symptoms between the two groups (P<0.05), and there were no significant changes in renal function and electrolytes before and after medication in the two groups of patients. Conclusion OSS had a higher quality of bowel cleaning and was easier for patients to accept.

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and the severity of intrauterine adhesions (IUA). MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions (TCRA) from December 2019 to March 2025. Based on the American Fertility Society (AFS) classification, patients were divided into mild (n=61), moderate (n=225), and severe (n=94) groups. NLR, PLR, and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR, PLR, and SII were significantly higher in the severe IUA group compared to the mild group (P<0.05), with SII showing the strongest predictive ability (OR=1.004, P=0.001). The number of intrauterine procedures was an independent risk factor (OR=1.27/level, P=0.016). The predictive model [Logit(P)=-0.676+0.241×operation times+0.004×SII] effectively identified severe IUA cases. ConclusionInflammatory markers (particularly SII) are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

ObjectiveTo systematically evaluate the association between serum indirect bilirubin (IBIL) levels and the risk of stroke incidence in patients with cardiovascular-kidney-metabolic (CKM) syndrome stages 0-3. MethodsA total of 48 301 participants with CKM syndrome stages 0-3 were included, during which 2 904 stroke events were recorded. A prospective cohort study design was employed. Cox proportional hazards regression models were used to analyze the relationship between IBIL and stroke risk, and restricted cubic spline (RCS) regression was applied to examine the dose-response relationship. Threshold effect analysis was conducted to identify potential inflection points in nonlinear relationships. ResultsMultivariable Cox regression analysis showed that in the overall population, each 1 μmol/L increase in IBIL level was associated with approximately a 1.2% reduction in stroke risk (HR = 0.988, 95% CI: 0.979-0.996, P < 0.05). A significant interaction was observed between IBIL and CKM stages in relation to stroke risk (Pinteraction < 0.05). In individuals with stages 0–2 of CKM syndrome, higher IBIL levels showed a significant inverse association with stroke risk (Ptrend < 0.05); however, no such association was observed in stage 3 patients. RCS regression and threshold effect analysis further revealed a nonlinear relationship between IBIL levels and stroke risk in stage 3 CKM patients (Plog-likelihood ratio < 0.05). When serum IBIL exceeded 10.980 μmol/L, each 1 μmol/L increase was associated with approximately 5.7% increase in stroke risk (HR = 1.057, 95% CI: 1.009–1.107, P < 0.05). ConclusionThe correlation between serum IBIL and stroke varies across different stages of CKM syndrome, showing a significant negative association in individuals at stages \0–2, while in stage 3 patients, it exhibits a threshold effect with an inflection point at 10.980 μmol/L.

ObjectiveTo investigate the uric acid-lowering effects and mechanisms of acacetin on hyperuricemia (HUA) in mice. MethodsOteracil potassium and adenine were used to establish the mouse model of HUA. Male Kunming mice (n=48) were randomized into six groups: control, model, low-dose (12.5 mg·kg-1) acacetin, medium-dose (25 mg·kg-1) acacetin, high-dose (50 mg·kg-1) acacetin, and allopurinol (10 mg·kg-1). Each group received continuous gavage administration for 21 days. An automatic biochemical analyzer was used to measure the levels of uric acid (UA), creatinine (Cr), urea nitrogen (BUN), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Additionally, the activity of xanthine oxidase (XOD) in the liver and the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-18 in the serum were measured by enzyme-linked immunosorbent assay (ELISA). Pathological changes in the renal tissue were observed by hematoxylin-eosin (HE) staining. Western blot was employed to determine the levels of glucose transporter 9 (GLUT9), urate transporter 1 (URAT1), phospho-NF-κB p65 (p-NF-κB p65), and nucleotide-binding oligomerization domain-like receptor pyrin domain-containing 3 (NLRP3) in the renal tissue. ResultsCompared with the control group, the model group showed elevated levels of UA, Cr, BUN, ALT, and AST, increased activity of XOD in the liver(P<0.01), raised levels of TNF-α, IL-1β and IL-18 in the serum(P<0.01), and significantly up-regulated expression of GLUT9, URAT1, p-NF-κB p65, and NLRP3 in the renal tissue(P<0.01). Compared with the model group, acacetin reduced the UA level in a dose-dependent manner, significantly improved liver and kidney functions, decreased the XOD activity in the liver, ameliorated the pathological changes in the renal tissue, down-regulated the expression of GLUT9, URAT1, p-NF-κB p65 and NLRP3 in the renal tissue(P<0.01), and lowered the levels of TNF-α, IL-1β, and IL-18 in the serum(P<0.01). ConclusionAcacetin can ameliorate HUA by decreasing uric acid production, increasing uric acid excretion, and inhibiting the NF-κB/NLRP3 signaling pathway. Therefore, acacetin may be a potential drug for the treatment of HUA.
