[Objective] To investigate the implementation of emergency transfusion strategy of uncrossmatched type O suspended RBCs based on the single-center clinical practice, which is "emergency transfusion is initiated by the authorized doctor of the emergency department, and no more than 4 U of type O uncrossmatched suspended RBCs are issued within 15 minutes in the transfusion department"(referred as the Practice), so as to provide reference for blood management. [Methods] A retrospective analysis of the information of patients who received uncrossmatched type O suspended RBCs in West China Hospital of Sichuan University from August 2019 to April 2024 was conducted. The analysis included reasons for emergency blood transfusion, time of receiving transfusion application and blood distribution, total bilirubin, indirect bilirubin, lactate dehydrogenase before and after transfusion, blood group of patients, and disease outcome. [Results] From August 2019 to April 2024, 39 cases applied for emergency transfusion of type O suspended RBCs, and a total of 90 U uncrossmatched suspended RBCs were transfused. All patients were Rh(D) positive, including 14 cases of blood group A, 6 cases of blood group B, 16 cases of blood group O, 2 cases of blood group AB, one case of undetermined blood group, and 2 cases with positive antibody screening. The main cause of emergency transfusion of type O suspended RBCs was traffic accident, accounting for 46% (18/39), with a mortality rate at 51.28% (20/39). The cause of death was primary injury, and no adverse reactions were reported. There was no significant difference in total bilirubin (TBIL), indirect bilirubin (IBIL) and lactate dehydrogenase (LDH) before and after blood transfusion (P>0.05). The median duration from admission to receiving transfusion application was 30.20 minutes, and 5.30 minutes from receipt of the application to blood distribution. [Conclusion] The single-center based Practice is safe, but there is room for optimization before the link of blood transfusion application sent to the transfusion department when applying for emergency transfusion of type O suspended RBCs.

AIM: To evaluate the repeatability and accuracy of iCare IC100 tonometer in measuring intraocular pressure(IOP)by comparing the correlation and difference with Goldmann applanation tonometry(GAT)and non-contact tonometer(NCT), and to compare the correlation of the three types of IOP measurement with the central corneal thickness(CCT).METHODS: Prospective study. A total of 90 outpatients(90 eyes)in Liaoning Aier Eye Hospital from March 2019 to May 2019 were randomly selected as study subjects. All patients were measured IOP using iCare IC100, NCT, and GAT. The interclass correlation coefficient(ICC)was used to evaluate the repeatability of IOP measured 3 times consecutively using an intraocular tonometer. The correlation and consistency of iCare IC100, GAT and NCT were compared by one-way ANOVA, Pearson linear correlation analysis and Bland-Altman analysis. The linear regression analysis was used to analyze the correlation of the three tonometers with CCT.RESULTS: The mean IOP measured with iCare IC100, GAT and NCT was 19.74±6.90, 19.88±7.07 and 18.47±6.31 mmHg, respectively(F=1.180, P=0.309). The measurements of iCare IC100 with GAT, iCare IC100 with NCT and GAT with NCT were all positively correlated(r=0.930, 0.946, 0.918, all P<0.05), the Bland-Altman analysis showed that the mean differences between iCare IC100 and GAT, iCare IC100 and NCT, GAT and NCT were -0.142±2.61, 1.27±2.24, and 1.41±2.81 mmHg, respectively, with 97%(87/90), 96%(86/90), and 97%(87/90)IOP differences distributed within their 95% confidence intervals. The IOP measured with iCare IC100 and CCT, GAT and CCT and NCT and CCT were all positively correlated(r=0.426, 0.353, 0.451, all P<0.01). The linear regression equations between iCare IC100, GAT and NCT measurement and CCT were iCare IC100 IOP=-19.62+0.074×CCT; GAT IOP=-13.54+0.063×CCT; NCT IOP=-19.65+0.072×CCT; that is, for every 10 μm increase in CCT, iCare IC100 measurement increased by 0.74 mmHg, GAT measurement increased by 0.63 mmHg, and NCT measurement increased by 0.72 mmHg.CONCLUSION: The iCare IC100 tonometer has good repeatability and accuracy in measuring IOP, and the CCT has a greater impact on the measurement of iCare IC100 than the GAT and NCT.

ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation, migration, and aerobic glycolysis of hepatocellular carcinoma (HCC) using cell experiments, as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected, and Sprague-Dawley rats were randomly divided into blank serum group, inhibitor group, and high-, middle-, and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells; glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells; RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression, related proteins, and phosphorylation of the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group, the Biejia Decoction Pill groups had significant reductions in OD value, migration rate during different periods of time, glycolytic rate-limiting enzymes (hexokinase, phosphofructokinase, pyruvate kinase), and glycolytic metabolites (pyruvate, lactic acid, ATP) (all P<0.05). RT-qPCR results showed that compared with the blank serum group, the high-, middle-, and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR, and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT (all P<0.05). Western blot results showed that compared with the blank serum group, the high-, middle-, and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins, and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins (all P<0.05). ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells, thereby inhibiting their proliferation and migration, possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.

Objective: To explore the possibility of performing allogeneic platelet-rich plasma (PRP) treatment for patients who were not suitable for autologous PRP collection through case reports of two patients with refractory wounds treated with allogeneic PRP. Methods: The ABO-compatible allogeneic whole blood was centrifuged 3 times to obtain allogeneic PRP within 6 hours of blood collection. Then the qualified allogeneic PRP was applied to 2 cases of refractory wound on the same day. Results: The platelet concentration in allogeneic PRP was higher than 1 000×10
/L, and the test results of infectious diseases, as well as the mixing of red blood cells and white blood cells, met the standard of quality control. Both patients achieved satisfactory wound healing outcomes (3 d). Conclusions: For patients who were not suitable for autologous PRP treatment, allogeneic PRP might be a new option.

INTRODUCTION:
Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration.
METHOD:
An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded.
RESULTS:
The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations.
CONCLUSION
The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

BACKGROUND:
The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC).
METHODS:
A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS).
RESULTS:
After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade.
CONCLUSION
Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

ObjectiveTo study the regulatory effects of Yinchenhao Tang combined with Yinchen Zhufu Tang on the expression of regulatory T (Treg)/helper T 17 (Th17) cells cultured in vitro from the patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsFresh peripheral blood was collected from the patients with HBV-ACLF for the separation of peripheral blood mononuclear cells (PBMCs). Immunomagnetic beads were used to isolate primary Treg and naive CD4+ T cells. After in vitro expansion, naive CD4+ T cells were induced to differentiate into Th17 cells. Rats were treated with the clearing method (Yinchenhao Tang), warming method (Yinchen Zhufu Tang), and combination of clearing method with warming method (Yinchenhao Tang combined with Yinchen Zhufu Tang, also known as Wenyang Jiedu Huayu Prescription), respectively, and then the medicated plasma samples were collected. Meanwhile, blank plasma was collected from the rats treated with normal saline. Cells were classified into blank, clearing method (5.04 g·kg-1), warming method (6.21 g·kg-1), and combination of clearing method with warming method (17.1 g·kg-1) groups and treated with corresponding plasma. The frequency of Treg/Th17 cells was detected by flow cytometry. The level of transforming growth factor-β (TGF-β) was measured by the enzyme-linked immunosorbent assay. The cytometric bead array (CBA) was employed to measure the levels of interleukin-10 (IL-10), interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), and interleukin-23 (IL-23). The mRNA and protein levels of Forkhead box P3 (FoxP3) and retinoic acid-related orphan receptor-gamma t (ROR-γt) were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the combination of clearing method with warming method group showed decreased frequency of Treg and Th17 cells, lowered levels of Treg cytokines (TGF-β and IL-10) and Th17 cytokines (TNF-α, IL-17A, and IL-23), and down-regulated mRNA and protein levels of FoxP3 and ROR-γt (P<0.01). Compared with the clearing method group, the combination of clearing method with warming method group showed decreased Treg cell frequency and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, lowered levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05, P<0.01). Compared with the warming method group, the combination of clearing method with warming method group showed decreased frequency of Treg cells and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, declined levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05). ConclusionThe combination of clearing method with warming method can down-regulate the expression of specific cytokines of Treg and Th17 cells, inhibit the over activation of Treg and Th17 cells, and reduce the secretion of cytokines such as TGF-β, IL-10, TNF-α, IL-17A, and IL-23, thereby alleviating inflammation and improving the prognosis of the patients with liver failure.
