Patients with inflammatory bowel disease (IBD) require long-term pharmacotherapy. Due to the wide variety of clinically available drugs, medication safety has become increasingly concerning. As an indispensable component of pharmaceutical formulations, drug excipients may induce various adverse reactions, including rash, allergic responses, and gastrointestinal discomfort, and may even lead to severe organic injury. However, they are often overlooked in clinical practice. Therefore, identifying and managing excipient-related adverse reactions is crucial for ensuring medication safety. To address this issue, this article systematically reviews common excipients in IBD therapeutics, the underlying mechanisms of excipient-induced adverse reactions, and corresponding management strategies, aiming to enhance clinicians' awareness of excipient-related issues, improve their ability to recognize and manage such reactions, and ultimately ensure patient safety.

Gastroblastoma (GB) is a rare gastric epithelial tumor without special clinical manifestations, whose histologic origin and pathogenesis remain unclear due to less related reports.Low-grade cell forms with biphasic differentiation are typical histological characteristics of GB.Immunohistochemistry and molecular tests can help with its differential diagnosis.GB is an invasive low-grade malignant tumor and the first treatment is surgical resection.However, there is no uniform standard treatment plan at present and most patients have a good prognosis.In this article, the histopathology, diagnosis and identification diagnosis of GB was reviewed to provide a theoretical basis for its origin, development, treatment and patient prognosis.

Objective:To explore the value of lumbar volumetric bone mineral density (vBMD) measured by quantitative computed tomography (QCT) in predicting coronary artery calcification (CAC).Methods:This retrospective, cross-sectional study included a total of 991 patients (504 male and 487 female) who underwent coronary artery CT angiography (CTA) and chest, abdomen, or lumbar spine CT examinations at Taihe County People′s Hospital from January 2023 to June 2024. Lumbar vBMD was measured by QCT. The coronary artery calcification score (CACS) was calculated using an artificial intelligence-assisted diagnostic system. Patients were categorized into a low calcification group (CACS≤100, 592 cases) and a moderate-to-severe calcification group (CACS>100, 399 cases). Independent-sample t-tests, Mann-Whitney U tests, or χ2 tests were employed to analyze the differences in clinical data and lumbar vBMD between the two groups. Binary logistic regression was employed to control confounding factors and analyze the correlation between lumbar vBMD and moderate-to-severe CAC. Multivariate binary logistic regression was used to identify independent predictors of moderate-to-severe CAC and construct a combined prediction model. The receiver operating characteristic curve was used to evaluate the efficacy of lumbar vBMD and the combined model in predicting moderate-to-severe CAC. The comparison of the area under the curve (AUC) was conducted using the DeLong test. Results:The age, incidence of diabetes, hypertension, and osteoporosis were significantly higher in the moderate-to-severe calcification group than in the low calcification group, while lumbar vBMD was significantly lower in the former group (all P<0.05). The body mass index, smoking history, and hyperlipidemia had no statistical differences between the two groups (all P>0.05). Following adjustment for potential confounding variables, the results of binary logistic regression analysis revealed that lumbar vBMD was not significantly associated with the presence of moderate-to-severe CAC in the overall study population or in male ( OR=0.998, 95% CI 0.993-1.003, P=0.379; OR=1.000, 95% CI 0.993-1.006, P=0.918). However, lumbar vBMD was a statistically significant predictor in females ( OR=0.992, 95% CI 0.985-0.999, P=0.032). Multivariate binary logistic regression analysis further demonstrated that age ( OR=1.048, 95% CI 1.019-1.077, P=0.001), hypertension ( OR=2.649, 95% CI 1.719-4.082, P<0.001), and lumbar vBMD ( OR=0.992, 95% CI 0.984-0.999, P=0.022) were independent predictors of moderate-to-severe CAC in women. The AUC of lumbar vBMD for predicting moderate-to-severe CAC in female patients was 0.684 (95% CI 0.641-0.725), and the AUC of the combined model was 0.746 (95% CI 0.705-0.784), with a statistically significant difference ( Z=3.26, P=0.001). Conclusions:Lumbar vBMD measured by QCT is an independent predictor of moderate-to-severe CAC in women and demonstrates moderate predictive value. The predictive performance can be enhanced by integrating age and hypertension into a combined predictive model.

The fluid status and rate of blood flow through the arteriovenous fistula (AVF) are two important factors affecting hemodynamic in hemodialysis patients; however, their effects on pulmonary hypertension have rarely been studied. Hence, we aimed to evaluate the effects of these factors in hemodialysis patients with pulmonary hypertension. Methods: This single-center cross-sectional survey included 219 maintenance hemodialysis patients (139 [63.5%] male). The prevalence of pulmonary hypertension was 13.6% (30 of 219). Pulmonary artery pressure was measured by echocardiography, fluid status was measured objectively using bioimpedance spectroscopy, and blood flow rate in the AVF (Qa) was determined using Doppler ultrasound. Results: The overall mean overhydration before hemodialysis was 1.5 L (range, 0.6–2.8 L). The mean overhydration in patients with and without pulmonary hypertension was 3.6 L (range, 2.3–4.6 L) and 1.4 L (range, 0.6–2.4 L), respectively (p < 0.001). The overall mean Qa was 780 mL/min (range, 570–1,015.5 mL/min). The mean Qa of patients with and without pulmonary hypertension was 672 mL/min (range, 505.7–982.2 mL/min) and 790 mL/min (range, 591–1,026 mL/min), respectively (p = 0.27). Overhydration (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.08–1.97; p = 0.01), N-terminal prohormone of brain natriuretic peptide (NT-proBNP; OR, 1.36; 95% CI, 1.09–1.71; p = 0.007), and left atrial diameter (OR, 1.14; 95% CI, 1.01–1.28; p = 0.03) were risk factors. Conclusion: Pulmonary hypertension is strongly associated with overhydration, NT-proBNP, and left atrial diameter in hemodialysis patients

Objective To investigate the correlations of serum eukaryotic translation promoter 2α (eIF2α) and activated transcription factor 4 (ATF4) levels with the degree of renal tissue injury and renal function in patients with diabetic nephropathy (DN). Methods A total of 102 patients with DN (DN group) and 102 patients with simple diabetes (control group) were selected. According to the severe degree of renal tissue damage, the patients with DN were divided into microalbuminuria group (MG group, 35 cases) and dominant albuminuria group (PG group, 41 cases) and renal dysfunction group (RIG group, 26 cases). Serum levels of eIF2α, ATF4, urea nitrogen (BUN), creatinine (Scr), cystatin C (CysC) and estimated glomerular filtration rate (eGFR) were measured. Pearson correlation analysis was used to explore the correlations of eIF2α and ATF4 with BUN, Scr, CysC and eGFR; multivariate Logistic regression analysis was used to explore the risk factors of DN; receiver operating characteristic (ROC) curve was used to analyze the value of eIF2α and ATF4 in diagnostic of DN. Results Serum levels of eIF2α, ATF4, BUN, Scr and CysC in the DN group were higher than those in control group, eGFR was lower than that in control group (P < 0.05). Serum eIF2α and ATF4levels in the RIG group were higher than those in PG and MG groups (P < 0.05). Serum eIF2α and ATF4 levels in DN patients were positively correlated with BUN, Scr and CysC, and negatively correlated with eGFR (P < 0.05). Long duration of diabetes, higher body mass index, high level of eIF2α and high level of ATF4 were risk factors for DN (P < 0.05). The area under the curve of eIF2α and ATF4 in diagnosis DN was 0.770 and 0.799, respectively, and the area under the curve of their combined diagnosis was 0.879, which was higher than that of single diagnosis (P < 0.05). Conclusion Serum levels of eIF2α and ATF4 are increased in patients with DN, which is related to the severity of renal injury and renal dysfunction in DN. The combination of eIF2α and ATF4 is of high value in the diagnosis of DN.

Objective:To investigate the short-term transplantation effect of different vitrification sollutions in order to optimize the cryopreservation protocol on human ovarian tissue.Methods:Ovarian tissues came from 4 patients who were treated surgically due to gynecological diseases in Peking University Shenzhen Hospital from March 2018 to December 2019. The size of 5-10 mm×10 mm×1 mm ovarian tissues were distributed to fresh control group and four experimental groups (G1, G2, G3 and G4). After equilibrium and thawing, the frozen ovarian tissues were grafted into chorioallantoic membrane (CAM). The transplanted ovarian tissues were collected 5 d after transplantation. The morphology of follicles was assessed by HE, the expression of CD105 protein was detected by immunohistochemistry and the microvascular density was recorded. The expression of Bcl-2 and Bax proteins was detected by Western blotting.Results:There was a significantly difference in the percentage of morphologically normal primordial follicles (MNPF) among G1 [63.2% (24/38)], G2 [68.3% (28/41)], G3 [61.9% (26/42)], G4 [69.6% (32/46)] and fresh control groups [82.8% (82/99), P=0.044]. Compared with fresh control group, the percentages of MNPF were statistically lower in the treatment groups (all P<0.05). The CD105-microvascular density (MVD) in fresh control group, G1, G2, G3 and G4 groups were 6.51±1.30/mm 2, 11.10±1.62/mm 2, 13.04±1.84/mm 2, 9.11±1.09/mm 2, 11.28±1.62/mm 2, respectively. The CD105-MVD in four treatment groups after transplantation was significantly higher than that of fresh control group ( P<0.001, P<0.001, P=0.022, P<0.001), and the CD105-MVD of G1, G2 and G4 groups was higher than that of G3 group ( P=0.024, P<0.001, P=0.034). The ratio of Bcl-2/Bax in G1, G2, G3, G4 groups and fresh control group were 0.71±0.37, 0.84±0.29, 0.45±0.18, 0.84±0.29 and 0.44±0.21, respectively. The ratio of Bcl-2/Bax of G2 group was statistically higher than that of fresh control group and G3 group ( P=0.025, P=0.038). Conclusion:After 5 d of transplantation into CAM, the percentage of normal primordial follicles is lower. Acorrding to the higher vascularization and anti-apoptotic ability, G2 and G4 are the optimal vitrification protocol for human ovarian tissue cryopreservation.
