ObjectiveThis study aims to systematically analyze the blood-absorbed components and metabolic profiles of Xiebaisan（XBS） in normal and chronic bronchitis （CB） mice using ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， while comparing differences between the two states. MethodsThirty female BABL/c mice were randomly divided into the normal group， the normal drug administration group， the CB group， the CB drug administration group and the dexamethasone group， with 6 mice in each group. The CB mouse model was established by inducing with ovalbumin （OVA）. The mice in the normal drug administration group and the CB drug administration group started to be gavaged with XBS（13.2 g·kg^-1） from the 21^st day， and the dexamethasone group mice were simultaneously gavaged with dexamethasone （0.5 mg·kg^-1） until the end of the 35^th day of the experiment. Subsequently， serum samples were collected and evaluated for their efficacy， based on the pharmacological evaluation indicators， to determine the efficacy of XBS in treating CB. Then the UPLC-Q-Exactive Orbitrap MS was employed to identify and analyze the chemical constituents， blood-absorbed components， and metabolites of XBS. Chemometric analysis was conducted to reveal metabolic profile differences under "dual states". Concurrently， Real-time PCR technology was utilized to detect the expression levels of key liver metabolic enzymes CYP2E1， CYP3A1， UGT1A1， and UGT1A6. ResultsA total of 28 prototype components and 158 metabolites （including 48 phase Ⅰ metabolites and 110 phase Ⅱ metabolites） of XBS were unambiguously identified in the serum of normal mice. Additionally， a comprehensive characterization was performed on a total of 32 prototype components and 178 metabolites （including 50 phase Ⅰ metabolites and 128 phase Ⅱ metabolites） of XBS in the serum of CB mice. Among them， 27 prototype components were detected in both states， including 12 flavonoids， 2 alkaloids， 3 triterpenes， 4 organic acids， 3 amides， 1 stilbene and 2 other compounds. The chemometrics analysis revealed no significant difference in the prototype components and metabolites of XBS between normal and CB mice； however， there was a significant increase in the in-vivo exposure of XBS in CB mice. Compared to normal mice， the levels of phase Ⅰ metabolites such as oxidation， reduction and methylation of blood components of XBS as well as phase Ⅱ metabolites of glucuronidation showed significant changes in CB mice. Real-time PCR further confirmed that these alterations were attributed to the upregulation of CYP2E1 （P<0.05）， CYP3A1 （P>0.05）， UGT1A1 （P<0.01） and UGT1A6 （P<0.01） enzymes expression in the liver of CB mice. ConclusionThis study elucidated the disparities in the levels of the blood-absorbed components and metabolic profiles of XBS in normal and CB mice， especially in oxidation， reduction， methylation in phase Ⅰ metabolism and glucoaldehyde acidification in phase Ⅱ metabolism. And there are related to the differences in the expression levels of phase Ⅰ and phase Ⅱ metabolic enzymes CYP2E1， CYP3A1， UGT1A1 and UGT1A6 in the liver.

Objective:To analyze the risk factors associated with intradialytic hypotension (IDH) in patients undergoing maintenance hemodialysis (MHD).Methods:This study used a cross-sectional design and included 150 adult patients who underwent MHD at The Third Affiliated Hospital of Anhui Medical University from January 2023 to March 2024. Relevant clinical data were collected to analyze the occurrence of IDH in patients undergoing MHD over 3 months, and the associated risk factors.Results:Among the 150 patients undergoing MHD, there were 67 in the IDH group and 83 in the non-IDH group. The IDH group had a higher fibrinogen/albumin ratio (FAR) [89.41 (73.30, 114.50) vs. 76.56 (65.80, 89.60), χ2 = -3.55, P < 0.001], an older age [(68.46 ± 14.10) years vs. (61.30 ± 12.23) years, t = -3.33, P = 0.001], a longer dialysis duration [(4 (3.5, 4.0) hours vs. (4 (4.0, 4.0) hours), U = -2.11, P = 0.044], a greater ultrafiltration volume [(2.20 ± 0.74) L vs. (1.92 ± 0.82) L, t = -2.16, P = 0.032], a higher ultrafiltration rate [(8.90 ± 2.64) mL·h?1·kg?1 vs. (7.75 ± 2.91) mL·h?1·kg?1, t = -2.51, P = 0.013], and a higher ultrafiltration volume/dry body mass ratio [(33.75 ± 9.76) mL/kg vs. (30.21 ± 11.39) mL/kg, t = -2.11, P = 0.046] compared with the non-IDH group. In the IDH group, the proportion of patients with primary chronic glomerulonephritis was lower (19.4% vs. 37.3%, χ2 = 5.76, P = 0.016), fibrinogen levels were higher [(3.63 (3.15, 4.50) μg/L vs. (3.34 (2.90, 3.74) μg/L, U = -2.61, P = 0.009], albumin levels were lower [(41.26 ± 4.03) g/L vs. (43.42 ± 4.29) g/L, t = 3.15, P = 0.002], high-density lipoprotein cholesterol (HDL-C) levels were lower [0.90 (0.77, 1.09) mmol/L vs. 1.05 (0.84, 1.34) mmol/L, U = -2.77, P = 0.006], and C-reactive protein levels were higher [5.92 (2.79, 9.61) mg/L vs. 2.70 (0.99, 6.49) mg/L, U = -2.27, P = 0.023] compared with the non-IDH group. Multivariate logistic regression analysis indicated that higher FAR values ( OR = 1.030, P = 0.025), a history of chronic glomerulonephritis ( OR = 10.408, P = 0.012), older age ( OR = 1.062, P = 0.043), a high ultrafiltration volume/dry body mass ratio ( OR = 1.072, P = 0.037), and low HDL-C levels ( OR = 0.046, P = 0.015) are independent risk factors for IDH. The area under the receiver operating characteristic curve for FAR predicting IDH was 0.699 (95% CI: 0.571-0.827, P = 0.003). The combination of age, chronic glomerulonephritis, ultrafiltration volume/dry body mass ratio, HDL-C levels, and FAR for predicting IDH resulted in a receiver operating characteristic curve area of 0.839 (95% CI: 0.750-0.929, P < 0.001). Conclusions:Among the risk factors for IDH in patients undergoing MHD, FAR is independently associated with an increased risk of IDH and serves as a valuable predictor for its occurrence in these patients.

Thyroid nodules (TNs) are defined as discrete lesions within the thyroid gland. Pregnancy, as a unique physiological stage, presents challenges for both clinicians and pregnant women when TNs are detected. Epidemiological studies have shown that the occurrence and development of TNs are closely related to hormonal changes during pregnancy, geographical location, and iodine intake. Thyroid ultrasonography is the best imaging method for evaluating TNs in pregnant women, which requires combined screening with serological diagnosis and multidisciplinary consultation (clinical endocrinologists, thyroid surgeons, and gynecologists, etc.) to discuss treatment indications, methods, and appropriate timing. Meanwhile, monitoring and follow-up during pregnancy should be conducted to assess the prognosis of both the mother and the fetus. This article focuses on reviewing the relevant research progress of TNs during pregnancy, and provides references for diagnosis, intervention, and treatment of TNs in the gestational period.

Objective:To explore the causal relationships between human inflammatory proteins and keloids.Methods:This study was based on Mendelian randomization (MR) analysis. Human inflammatory proteins were considered as the exposure factors, and keloid was considered as the outcome. Data on 91 inflammatory proteins (14 824 samples) and keloids (668 samples) were obtained from the genome-wide association study database. A significance threshold was established to discern single nucleotide polymorphisms (SNPs) significantly associated with inflammatory proteins as instrumental variables with the influence of weak instrumental variables being excluded. For the analysis of a single instrumental variable, the Wald ratio method was used; for the analysis of multiple instrumental variables, the inverse variance weighted (IVW) method was used as the primary method, with the weighted median method, simple mode method, weighted mode method, and MR-Egger method as supplementary methods to employ two-sample MR analysis to analyze the causal relationships between inflammatory proteins and keloids. Using the IVW method, weighted median method, and MR-Egger method to employ multi-sample MR (MVMR) analysis to evaluate the statistically significant inflammatory proteins in the above-mentioned two-sample MR analysis, thus validating their independent causal relationships with keloids. For SNPs of inflammatory proteins conformed to the hypothesis, the Cochran Q test was used to assess heterogeneity, the MR-Egger regression test and MR-PRESSO outlier test were used to evaluate horizontal pleiotropy, and the leave-one-out analysis was performed to assess reliability.Results:Seventy-five inflammatory proteins met the exposure factor criteria, with the number of SNPs reaching a significance threshold ranging from 1 to 7 082 (with F values all >10), indicating minimal potential for weak instrumental variable bias in this study. The IVW method analysis revealed significant causal relationships between eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), CD5, and osteoprotegerin and keloids (with odds ratios of 0.50, 0.61, and 0.71, respectively, 95% confidence intervals of 0.32-0.77, 0.41-0.89, and 0.52-0.97, respectively, P<0.05); the weighted median method confirmed a significant causal relationship between CD5 and keloids (with odds ratio of 0.61, 95% confidence interval of 0.38-0.97, P<0.05); the simple mode method, weighted mode method, and MR-Egger method confirmed no significant causal relationships between CD5 and osteoprotegerin and keloids ( P>0.05). The Wald ratio method analysis revealed a significant causal relationship between programmed death-ligand 1 (PD-L1) and keloids (with odds ratio of 1.83, 95% confidence interval of 1.06-3.15, P<0.05). Thus IVW method results were considered as the standard. The IVW method analysis confirmed that 4E-BP1, CD5, osteoprotegerin, and PD-L1 maintained significant causal relationships with keloids (with odds ratios of 0.43, 0.58, 0.70, and 1.95, respectively, 95% confidence intervals of 0.28-0.67, 0.39-0.86, 0.51-0.95, and 1.16-3.27, respectively, P<0.05). The MR-Egger method confirmed significant causal relationships between 4E-BP1 and CD5 and keloids (with odds ratios of 0.41 and 0.58, respectively, 95% confidence intervals of 0.22-0.77 and 0.39-0.88, respectively, P<0.05). The weighted median method confirmed significant causal relationships between 4E-BP1 and PD-L1 and keloids (with odds ratios of 0.46 and 2.06, respectively, 95% confidence intervals of 0.26-0.82 and 1.11-3.81, respectively, P<0.05). The Cochran Q test assessment indicated no significant heterogeneity in the SNPs of CD5 and osteoprotegerin that had significant causal relationships with keloids ( P>0.05). The MR-Egger regression test and MR-PRESSO outlier test showed no significant horizontal pleiotropy in the SNPs of CD5 and osteoprotegerin that had significant causal relationships with keloids ( P>0.05). The leave-one-out analysis confirmed that the significant causal relationships between CD5 and osteoprotegerin and keloids remained stable after sequentially removing individual SNP. Conclusions:Two-sample MR analysis and MVMR analysis confirmed significant causal relationships between 4E-BP1, CD5, and osteoprotegerin and keloids, all of which are protective factors for keloids.
