Objective: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

Aim To explore the potential targets and related signaling pathways of Agaricus blazei Murill (AbM ) extract in the treatment of chronic myeloid leukemia (CML) based on liquid chromatography mass spectrometry ( LC-MS ), network pharmacology, molecular docking, and were further verified by experiments in vitro. Methods The active components of AbM extract were retrieved from LC-MS, Swiss Target Prediction database was used to predict related targets, and CML disease target genes were obtained from Gen- eCards and DisGeNET databases. After screening the common targets of drug and CML, the protein-protein interaction network of the common targets was performed by STRING, and GO and KEGG enrichment a- nalysis were done by DAVID database. Cytoscape software was used to construct the network of target protein. Molecular docking was carried out by DockThor, and the Pymol software was used to make a visual picture. The inhibitory effect of AbM extract on leukemia cells K562 was determined by CCK-8 experiment, and the effect of AbM extract on the expression and phosphorylation level of related proteins was verified by Western blot. Results The prediction results showed that 126 active components of AbM extract, and 172 common targets were collected. KEGG pathway analysis results showed that PI3K/Akt/mTOR signaling pathway might play an important role in the treatment of CML disease. The IC

Aim To investigate the regulatory effect of Cortaetin on pathological myocardial hypertrophy induced by isoprenaline (ISO) and the underlying mechanism. Methods ISO was used to stimulate neonatal rat cardiomyocytes for 24 h, and myocardial hypertrophy model was established at the cellular level. C57BL/6 mice were injected subcutaneously with ISO for one week to establish myocardial hypertrophy model at animal level. RT-qPCR was used to detect the changes of mRNA and Western blot was used to detect the changes of relative protein content. Immunofluorescence was used to measure the subcellular location of Cortaetin and the change of its expression. The overex-pression of Cortaetin by adenovirus infection and the knockdown of Cortaetin by transfection of small interfering RNA were studied. Results On the cellular and animal levels, ISO-induced myocardial hypertrophy models were successfully established, and it was observed that ISO caused the decrease of Cortaetin and N-cadherin protein levels. Overexpression of Cortaetin could reverse the decrease of N-cadherin protein level and myocardial hypertrophy caused by ISO. Knockdown of Cortaetin showed the opposite effect. Conclusion Cortaetin, in combination with N-cadherin, may play a role in combating myocardial hypertrophy by enhancing the connections between cardiomyocytes.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the application effect of F4.8 visualized puncture assisted microchannel percutaneous nephroli-thotomy(mPCNL)in the treatment of patients with calyceal diverticular calculus.Methods A total of 86 patients with calyceal diverticular calculus from January 2020 to January 2023 in Hefei First People's Hospital were selected and divided into the observation group and the conventional group according to random number table method,with 43 cases in each group.Patients in the conventional group were given mPCNL,while patients in the observation group were given F4.8 visualized puncture assisted mPCNL.The stone clearance rate immediately after surgery and 4 weeks after surgery,surgery and postoperative recovery,complications,as well as pre-and post-operative trauma stress indicators[serum cortisol(Cor),norepinephrine(NE),C-reactive protein(CRP),interleukin-6(IL-6)],interlobar renal artery hemodynamic indicators[peak systolic velocity(Vmax),end diastolic velocity(EDV),resistance index(RI)],and renal function indicators[urine kidney injury molecule-1(KIM-1),24 h urinary protein quantitation(24 h Upro),blood urea nitrogen(BUN),serum creatinine(Scr)]were compared between the two groups.Results The stone clearance rate immediately after surgery in the observation group was higher than that in the conventional group,the intraoperative blood loss was less than that in the conventional group,and the operation time,postoperative ambulation time,indwelling nephrostomy tube time,and hospitalization time were shorter than those in the conventional group,and the differences were statistically significant(P<0.05).The serum levels of Cor,NE,CRP and IL-6 1 day and 3 days after surgery in the two groups were higher than those before operation(P<0.05),while the serum levels of Cor,NE,CRP and IL-6 1 day and 3 days after surgery in the observation group were lower than those in the conventional group(P<0.05).The Vmax and EDV of renal interlobar artery 1 day after surgery in the observation group decreased compared with those before operation(P<0.05),while RI increased(P<0.05).The Vmax and EDV of renal interlobar artery 1 day and 3 days after surgery in the conventional group decreased compared with those before operation(P<0.05),while RI increased(P<0.05).The Vmax and EDV of renal interlobar artery 1 day and 3 days after surgery in the observation group were higher than those in the conventional group,while RI was lower than that in the conventional group,and the differences were statistically significant(P<0.05).The levels of KIM-1,24 h Upro,BUN,and Scr of urine 7 days after surgery in both groups were lower than those before surgery,and those in the observation group were lower than those in the conventional group,with statistically significant differences(P<0.05).There was no statistically significant difference in the incidence of complication between the two groups(P>0.05).Conclusion F4.8 visualized puncture assisted mPCNL for the treatment of calyceal diverticular calculus can improve surgical effect,reduce surgical trauma stress,and promote renal function recovery.
