Objective:To assess the effects of recognition function of four-lead electrocardiogram(ECG)synchronization technique and multi-parameter fusion technique in reducing the number of false alarms and improving the quality of alarms in intensive care units(ICU).Methods:Four-lead ECG synchronization technique and multi-parameter fusion technique were used to strengthen the monitoring and assessment for the alarm of clinical monitors,and reduce the false alarm rate of monitors.The clinical alarm data of bed units corresponding to 48 monitors in clinical use of ICU,cardiovascular intensive care unit(CCU)and neurosurgery intensive care unit(NICU)of Hainan General Hospital from October 14 to December 27,2024 were selected.According to the opening and close of the four-lead ECG synchronization and multi-parameter fusion technique algorithm of the monitors,they were divided into group A(opened four-lead ECG synchronization and multi-parameter fusion),group B(opened four-lead ECG synchronization,but closed multi-parameter fusion),group C(closed four-lead ECG synchronization,but opened multi-parameter fusion)and group D(closed four-lead ECG synchronization and multi-parameter fusion),with 12 units in each group.The numbers of total alarms and false alarms generated by monitor of each bed unit among different optimization strategies were compared.Results:The numbers of average daily alarm of the monitors in groups A,B and C were respectively(134.2±32.4)cases,(392.5±68.2)cases and(583.4±126.5)cases,which were lower than those in group D(1 073.2±168.6),with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).The optimization rates of the alarm numbers in groups A,B and C were increased by 87.51%,63.47%and 45.67%,respectively.The rates of average false alarm of the monitors in groups A,B and C were respectively(1.04±0.15)%,(1.73±0.12)%and(2.07±0.08)%,which were lower than(3.76±0.2)%in group D,with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).Conclusion:Four-lead ECG synchronization technique and multi-parameter fusion technique can effectively optimize the number of alarms in ICU,and reduce the proportion of false alarms of monitors in department,and decrease fatigue of medical staffs for alarm.

Objective:To explore the impact of tislelizumab on renal function in bladder cancer patients with hydronephrosisMethods:A retrospective analysis of 34 bladder cancer patients with hydronephrosis treated at the Second Hospital of Tianjin Medical University from July 2020 to September 2023. Among them, 27 were male, and 7 were female, with an average age of (67.41±11.06)years and a body mass index (BMI) of (29.00±7.34) kg/m 2. 18 patients (52.9%) had hypertension, 5 (14.7%) had diabetes, and 5 (14.7%) had coronary heart disease. The baseline serum creatinine (SCr) was 81.15(69.18, 108.90)μmol/L, and the estimated glomerular filtration rate (eGFR) was 73.86(62.17, 91.12)ml/(min·1.73m 2). Of these, 26 patients (76.5%) had eGFR ≥60 ml/(min·1.73m 2)(G60+ group), and 8 patients (23.5%) had eGFR <60 ml/(min·1.73m 2)(G60- group). 10 patients (29.4%) had non-muscle invasive bladder cancer (NMIBC), and 24(70.6%) had muscle-invasive bladder cancer (MIBC). Eleven patients received surgical interventions within 1 month before baseline data collection that might affect hydronephrosis. All 34 patients received tislelizumab (200 mg, intravenous infusion every 3 weeks) combined with albumin-paclitaxel (200 mg, intravenous infusion every 3 weeks). Serum creatinine values were recorded before cycles 1, 2, and 3, and 21 days after cycle 3 (Cr1, Cr2, Cr3, CrE), and corresponding eGFR values (eGFR1, eGFR2, eGFR3, eGFRE) were calculated. A reduction in eGFR >25% from baseline at any of these points was defined as a decline in renal function (DRF), and an increase in eGFR >25% was defined as improvement in renal function (IRF). Differences in renal function changes and IRF, DRF incidence rates were compared between baseline subgroups Results:After 3 cycles of tislelizumab treatment, there was no significant change in eGFR []eGFR1 vs. eGFRE, 73.86 (62.16, 91.12)ml/(min·1.73m 2) vs. 83.82 (60.32, 90.62) ml/(min·1.73m 2), P=0.197]. Subgroup analysis showed that patients with diabetes had a significant increase in CrE compared to Cr1 (88.90 μmol/L vs. 69.40 μmol/L, P=0.043) and a significant decrease in eGFRE compared to eGFR1 [76.47 ml/(min·1.73m 2) vs. 87.73 ml/(min·1.73m 2), P=0.043]. No significant differences were observed in the other subgroups for SCr and eGFR within or between groups. DRF occurred in 4 patients (11.8%), with 1 diagnosed with acute renal injury, but not immune-related. IRF occurred in 8 patients (22.9%). In the subgroup analysis, the IRF incidence was significantly higher in the G60-group compared to the G60+ group (50.0% vs. 15.4%, P=0.044). No other factors were found to be associated with DRF or IRF. Conclusions:Tislelizumab treatment is safe for renal function in bladder cancer patients with hydronephrosis. Most patients with baseline poor renal function or underlying conditions like hypertension, diabetes, or coronary heart disease showed stable renal function during treatment.

Parkinson's disease (PD) is a common neurodegenerative disease in middle-aged and elderly people. In particular, increasing evidence has showed that astrocyte-mediated neuroinflammation is involved in the pathogenesis of PD. As a precious traditional Chinese medicine, bear bile powder (BBP) has a long history of use in clinical practice. It has numerous activities, such as clearing heat, calming the liver wind and anti-inflammation, and also exhibits good therapeutic effect on convulsive epilepsy. However, whether BBP can prevent the development of PD has not been elucidated. Hence, this study was designed to explore the effect and mechanism of BBP on suppressing astrocyte-mediated neuroinflammation in a mouse model of PD. PD-like behavior was induced in the mice by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (30 mg·kg-1) for five days, followed by BBP (50, 100, and 200 mg·kg-1) treatment daily for ten days. LPS stimulated rat C6 astrocytic cells were used as a cell model of neuroinflammation. THe results indicated that BBP treatment significantly ameliorated dyskinesia, increased the levels of tyrosine hydroxylase (TH) and inhibited astrocyte hyperactivation in the substantia nigra (SN) of PD mice. Furthermore, BBP decreased the protein levels of glial fibrillary acidic protein (GFAP), cyclooxygenase 2 (COX2) and inducible nitric oxide synthase (iNOS), and up-regulated the protein levels of takeda G protein-coupled receptor 5 (TGR5) in the SN. Moreover, BBP significantly activated TGR5 in a dose-dependent manner, and decreased the protein levels of GFAP, iNOS and COX2, as well as the mRNA levels of GFAP, iNOS, COX2, interleukin (IL) -1β, IL-6 and tumor necrosis factor-α (TNF-α) in LPS-stimulated C6 cells. Notably, BBP suppressed the phosphorylation of protein kinase B (AKT), inhibitor of NF-κB (IκBα) and nuclear factor-κB (NF-κB) proteins in vivo and in vitro. We also observed that TGR5 inhibitor triamterene attenuated the anti-neuroinflammatory effect of BBP on LPS-stimulated C6 cells. Taken together, BBP alleviates the progression of PD mice by suppressing astrocyte-mediated inflammation via TGR5.
