Objective To evaluate the effects of parecoxib sodium for preemptive analgesia in patients undergoing cerebral angiography. Methods Sixty patients undergoing cerebral angiography were divided into two groups by random digits table with 30 cases in each : group P and group F. Patients in group P received parecoxib sodium 40 mg 30 min before operation, while group F received fentanyl 1 μ g/kg 2 min before operation. The changes of hemodynamics were observed before operation (To), immediately right internal carotid artery angiography during operation (T1), immediately right vertebral artery angiography (T2),immediately left internal carotid artery angiography(T3), immediately left vertebral artery angiography(T4), 10min after operation (T5). The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2)and visual analogue score (VAS) were recorded at different times during the whole operation. Results There were no significantly differences on MAP, HR and VAS between group P and group F (P > 0.05 ). But the SpO2 at T1 ,T2,T3 in group F (0.94±0.03,0.95±0.02,0.95±0.02) were significantly lower than those in group P (0.98 ± 0.01,0.98 ± 0.02,0.98 ± 0.02 )(P<0.05 ), and 2 cases SpO2 < 0.90 at Ti. Conclusion Parecoxib sodium administered preemptively provides a nice analgesic effect in patients undergoing cerebral angiography, and is more safe than fentanyl.

Objective To observe the leading effect of end-tidal pressure of carbon dioxide in artery ( PET CO2 ) on mechanical ventila-tion in New Zealand white rabbits, and to establish parameters for medical animal experiments in terms of hemodynamics, blood gas, blood glucose, electrolyte. Methods 31 anesthetized New Zealand rabbits were practiced tracheostomy tube and mechanical ventilation. Respira-tion rate was 40 breaths/min and tidal volume was adjusted so that PET CO2 was 29 mmHg. Invasive blood pressure, electrocardiogram and PET CO2 were monitored. Blood gas analysis, electrolyte, hemoglobin and blood glucose were tested. Results When PET CO2 was maintained at 29 mmHg, the results were as follows:PH (7.42 ±0.07), 95% confidenceinterval (7.40~7.45);PaCO2(38.5 ±5.8) mmHg, 95%confidenceinterval (36. 4~40. 6) mmHg;BE (1. 45 ± 2. 80) mmol/L,95% confidenceinterval (0. 43~2. 48) mmHg. Conclusion Moni-toring of PET CO2 is good to guide mechanical ventilation in New Zealand white rabbits.

Objective:To investigate the diagnostic performance of continuous-time random-walk (CTRW) diffusion model combined with vesical imaging-reporting and data system (VI-RADS) in the diagnosis of muscle invasion of bladder cancer.Methods:In this case-control study, 64 patients with pathologically confirmed bladder urothelial carcinoma in Peking University First Hospital were retrospectively enrolled from August 2022 to March 2023. The patients were divided into the muscle invasive bladder cancer (MIBC) group and the nonmuscle invasive bladder cancer (NMIBC) group (29 cases and 35 cases, respectively) according to the pathological results. All patients underwent bladder MRI within 4 weeks before surgery, including T 2WI, conventional diffusion weighted imaging (DWI), and multi-b-value DWI. The CTRW model was used to obtain three quantitative diffusion parameters, including D m (an anomalous diffusion coefficient), α (related to temporal diffusion heterogeneity), and β (related to spatial diffusion heterogeneity). The apparent diffusion coefficient (ADC) was calculated using a mono-exponential model. The VI-RADS scores were evaluated based on T 2WI and conventional DWI. The Mann-Whitney U test was used to compare the diffusion parameters between the MIBC group and the NMIBC group. The combination of the parameters was investigated with logistic regression analysis. The diagnostic performance for muscle invasion of bladder cancer was evaluated by receiver operating characteristic analysis and the area under the curve (AUC). The difference between AUC was compared using the DeLong test. Results:There were statistically significant differences in ADC, D m, and α between the MIBC group and the NMIBC group ( Z=-2.31, -2.91, -3.97, P=0.021, 0.004,<0.001). No significant difference was found in β between the two groups ( Z=1.69, P=0.091). The AUC (95% CI) of D m and α for diagnosing MIBC were 0.712 (0.587-0.838) and 0.790 (0.676-0.904) respectively, both of which were higher than that of ADC (AUC 0.669, 95% CI 0.537-0.801) with statistically significant differences ( Z=2.86, 2.27, P=0.004, 0.023). The AUC (95% CI) of CTRW (D m+α) was 0.782 (0.661-0.876), which was significantly higher than that of ADC ( Z=2.35, P=0.019). The AUC (95% CI) of VI-RADS score and VI-RADS combined with CTRW parameter (VI-RADS+D m+α) were 0.823 (0.716-0.930) and 0.900 (0.799-0.961) respectively, with a statistically significant difference between them ( Z=2.16, P=0.031). Conclusion:The D m and α parameters in the CTRW diffusion model show better performance than the ADC in the mono-exponential model for muscle-invasive evaluation of bladder cancer, and the CTRW diffusion model can enhance the diagnostic performance of VI-RADS.

BACKGROUND:
Triple-negative breast cancer (TNBC) is a type of highly invasive breast cancer with a poor prognosis. According to new research, long noncoding RNAs (lncRNAs) play a significant role in the progression of cancer. Although the role of lncRNAs in breast cancer has been well reported, few studies have focused on TNBC. This study aimed to explore the biological function and clinical significance of forkhead box C1 promoter upstream transcript (FOXCUT) in triple-negative breast cancer.
METHODS:
Based on a bioinformatic analysis of the cancer genome atlas (TCGA) database, we detected that the lncRNA FOXCUT was overexpressed in TNBC tissues, which was further validated in an external cohort of tissues from the General Surgery Department of the First Affiliated Hospital of Nanjing Medical University. The functions of FOXCUT in proliferation, migration, and invasion were detected in vitro or in vivo. Luciferase assays and RNA immunoprecipitation (RIP) were performed to reveal that FOXCUT acted as a competitive endogenous RNA (ceRNA) for the microRNA miR-24-3p and consequently inhibited the degradation of p38.
RESULTS:
lncRNA FOXCUT was markedly highly expressed in breast cancer, which was associated with poor prognosis in some cases. Knockdown of FOXCUT significantly inhibited cancer growth and metastasis in vitro or in vivo. Mechanistically, FOXCUT competitively bounded to miR-24-3p to prevent the degradation of p38, which might act as an oncogene in breast cancer.
CONCLUSION
Collectively, this research revealed a novel FOXCUT/miR-24-3p/p38 axis that affected breast cancer progression and suggested that the lncRNA FOXCUT could be a diagnostic marker and therapeutic target for breast cancer.

Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40%of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated he-patic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and ther-apeutic targets for liver protection.
