To investigate the risk factors for acute kidney injury (AKI) following the use of amphotericin B deoxycholate and to develop a predictive model to guide clinical monitoring and intervention.

Objective To mine and analyze signals of acute kidney injury(AKI)related to drugs,comprehensively summarize the potential risk drugs,and provide a reference for clinically safe medication.Methods The AKI reports from January 2004 to September 2023 in the US FDA Adverse Event Reporting System(FAERS)were retrieved.Disproportionality methods were used to explore the relationship between drugs and AKI,and demographic information,time to onset,and patient outcomes were analyzed.Results Out of 1 253 drugs,159 were identified as AKI signal drugs.Among these,there were 49 antimicrobial agents(30.82%),including 35 antibiotics and 14 antiviral agents;33 antineoplastic agents(20.75%);and 25 hypotensive agents(15.72%).Drug-related AKI occurred mostly in the elderly,and the male-to-female ratio was 124∶100.The median time to onset for AKI related to antibiotics was≤8 d,with the third quartile≤21 d.Rivaroxaban and aspirin had higher proportions of death reports,with 33.03%and 31.44%respectively.Conclusions A multitude of drugs pose a risk for acute kidney injury,necessitating caution in their clinical application and the implementation of monitoring of renal function.The elderly are a high-risk group for drug-related AKI,and there are more males than females.For antibiotics,the first 21 days are the key monitoring period.For drugs that require long-term use,regular monitoring is necessary.

OBJECTIVE To study the pharmacokinetic characteristics of ciprofol in pregnant and fetal rats， and provide reference for the application of ciprofol in cesarean section. METHODS Eight pregnant rats were selected. A single dose of 2.4 mg/kg of ciprofol was administered via the tail vein. One fetal rat was selected at 2， 4， 8， 12， 16， 25， 35， 45， 60， and 90 minutes respectively after ciprofol administration. Subsequently， whole blood samples were collected simultaneously from both the pregnant rats and fetal rats. HPLC-MS/MS method was used to determine the concentration of ciprofol in the bodies of pregnant and fetal rats. The ratios of fetal-to-maternal blood concentrations （F/M ratios） at each time point were calculated， and the F/M-time curves were plotted. Subsequently， non-compartmental pharmacokinetic parameters were computed using DAS 2.0 software. RESULTS Compared with pregnant rats， cmax， AUC0-90 min and AUC0-∞ of ciprofol in fetal rats were decreased significantly， while MRT was increased significantly （P＜0.05）. The F/M curve of ciprofol initially increased and then decreased， and between 0.16- 0.84， reaching a maximum value of 0.84 at 45 minutes. CONCLUSIONS Ciprofol can penetrate the placental barrier， and there are significant differences in pharmacokinetic parameters between pregnant and fetal rats. Moreover， the exposure level of ciprofol in fetal rats is much lower than that in pregnant rats. Therefore， ciprofol shows promise as an ideal anesthetic agent for cesarean section delivery.

To evaluate the clinical safety of four CD19-targeted and two BCMA-targeted chimeric antigen receptor T-cell (CAR-T) therapies.

Although cancer immunotherapy has made great strides in the clinic, it is still hindered by the tumor immunosuppressive microenvironment (TIME). The stimulator of interferon genes (STING) pathway which can modulate TIME effectively has emerged as a promising therapeutic recently. However, the delivery of most STING agonists, specifically cyclic dinucleotides (CDNs), is performed intratumorally due to their insufficient pharmacological properties, such as weak permeability across cell membranes and vulnerability to nuclease degradation. To expand the clinical applicability of CDNs, a novel pH-sensitive polycationic polymer-modified lipid nanoparticle (LNP-B) system was developed for intravenous delivery of CDNs. LNP-B significantly extended the circulation of CDNs and enhanced the accumulation of CDNs within the tumor, spleen, and tumor-draining lymph nodes compared with free CDNs thereby triggering the STING pathway of dendritic cells and repolarizing pro-tumor macrophages. These events subsequently gave rise to potent anti-tumor immune reactions and substantial inhibition of tumors in CT26 colon cancer-bearing mouse models. In addition, due to the acid-sensitive property of the polycationic polymer, the delivery system of LNP-B was more biocompatible and safer compared with lipid nanoparticles formulated with an indissociable cationic DOTAP (LNP-D). These findings suggest that LNP-B has great potential in the intravenous delivery of CDNs for tumor immunotherapy.

Cold tumors have a poor response to tumor immunotherapy due to low immune cell infiltration and the ability to evade immune attacks. Converting cold tumors into hot tumors can enhance the clinical effectiveness of anti-tumor immunotherapy. High-intensity focused ultrasound (HIFU) as a non-invasive treatment can damage tumors through mechanical effects, but there is a lack of research on its cytotoxic mechanisms at the cellular level and its role in inducing anti-immune responses. In this study, the role of HIFU in triggering tumor ferroptosis by disrupting the GSH/GSSG balance through mechanochemical action and the associated anti-tumor immune priming effect were investigated. The use of a nano-enhancer loaded with PFOB combined with HIFU could enhance ferroptosis in triple-negative breast cancer at a specific stage of tumor growth (UTGR = 0) while promoting the conversion of a cold tumor into a hot tumor, thereby improving the immune response. Overall, this provides valuable guidance for the clinical application of HIFU in tumor immunotherapy.

Objective:To investigate the short-term efficacy and safety of rituximab (RTX) in children with calcineurin inhibitor (CNI) resistant steroid resistant nephrotic syndrome (SRNS).Methods:A retrospective case analysis was conducted. Thirteen children with CNI resistant SRNS who were regularly treated with RTX (375 mg/m 2 per dose (maximum dose 500 mg), 1 dose per week, a total of 4 doses) in Department of Nephrology, Children′s Hospital of Fudan University from January 2016 to December 2023 were enrolled. The general data, disease related information, urinary protein/creatinine, serum albumin, blood creatinine before RTX treatment, immunosuppressants, adverse events, and monthly urinary protein/creatinine, serum albumin, and blood creatinine indexes within 6 months after RTX treatment were collected. The changes of urinary protein/creatinine, serum albumin and estimated glomerular filtration rate (eGFR) before and after RTX at 3 and 6 months were analyzed by using paired sample t test and Wilcoxon signed-rank test. Results:Among the 13 patients, 8 were male and 5 were female. The age of disease onset was 4.0 (2.9, 6.8) years and the age of RTX treatment was 9.8 (5.9, 13.6) years. There were 8 cases of focal segmental glomerulosclerosis, 3 cases of minimal change disease and 2 cases of mesangial proliferative glomerulonephritis. No clinically significant gene variation was detected in 12 cases and the other one did not receive gene test. Before RTX treatment, 11 cases were in chronic kidney disease stage G1, and 1 case each was in stage G2 and stage G3. Ten children completed 4 doses of RTX treatment, 1 patient completed 3 doses, and 2 patients completed 2 doses. Urinary protein/creatinine in 13 children at 3 and 6 months after RTX treatment was significantly lower than baseline (0.60 (0.13, 2.04), 0.49 (0.28, 1.10) vs. 1.44 (0.76, 4.11) mg/mg, Z=-2.34, -2.34, both P<0.05), and serum albumin was significantly higher than baseline ((35±8), (34±7) vs. (30±6) g/L, t=2.30, 2.60, both P<0.05). The eGFR at 6 months after RTX treatment was not significantly different from the baseline ((110±32) vs. (113±35) ml/(min·1.73 m 2), t=-0.76, P>0.05)). No serious adverse reactions occurred in this study. Conclusion:RTX could reduce urinary protein and increase serum albumin in short-term treatment in children with CNI resistant SRNS without significant side effects.

BACKGROUND:Previous studies have indicated that cathepsin K can intervene with the occurrence and development of osteoporosis by regulating bone mineral density in middle-aged and older adults. However,whether there is a causal relationship between the cathepsin family and bone mineral density in other populations remains unknown. OBJECTIVE:To investigate the causal relationship between cathepsin and bone mineral density.METHODS:Genetic loci associated with eight cathepins were extracted from the IEU Open GWAS database as instrumental variables,and bone mineral density values in five age groups acted as an outcome. The causal relationship between cathepin and bone mineral density was assessed by two-way Mendelian randomization analysis. Heterogeneity of the genetic instrumental variables was assessed using Cochran's Q test,pleiotropy was assessed using the MR-Egger intercept test,and the sensitivity of single nucleotide polymorphisms used as instrumental variables to the causal effect of exposure and outcome was assessed using the leave-one-out method. RESULTS AND CONCLUSION:The results of the inverse variance weighting method with positive Mendelian randomization showed that cathepin H was negatively associated with bone mineral density in people aged 45-60 years[odds ratio (95％ confidence interval)=0.965(0.94-0.99),P=0.04];cathepin Z was negatively associated with bone mineral density in people aged 30-45 year[odds ratio (95％ confidence interval)=1.06 (1.00-1.11),P=0.03]. The results of sensitivity analysis showed a stable causal relationship,and MR-Egger intercept analysis did not detect potential horizontal pleiotropy. The inverse Mendelian randomization results showed that bone mineral density had no significant inverse effect on cathepin. The above results confirm that cathepin can affect bone mineral density in some age groups,which may increase the risk of osteoporosis and should be given more attention.
