Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P>0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

The alternative pathway (AP) of the complement system is a key contributor to the pathogenesis of several diseases including paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), C3 glomerular disease (C3G) and age-related macular degeneration (AMD). Complement factor B (CFB) is a trypsin-like serine protein that circulates in the human bloodstream in a latent form. As a key node of the alternative pathway, it is an important target for the treatment of diseases mediated by the complement system. With the successful launch of iptacopan, the CFB small molecule inhibitors has become a current research hotspot, a number of domestic and foreign pharmaceutical companies are actively developing CFB small molecule inhibitors. In this paper, the research progress of CFB small molecule inhibitors in recent years is systematically summarized, the representative compounds and their activities are introduced according to structural types and design ideas, so as to provide reference and ideas for the subsequent research on CFB small molecule inhibitors.

Background:
In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes.
Methods:
The degree of tissue injury was observed by pathological staining. Inflammatory cell infiltration was analyzed by immunohistochemical staining. Serum EPO levels were detected by enzyme-linked immunosorbent assay, and EPO production and renal interstitial fibrosis were analyzed by immunofluorescence. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of key inflammatory factors and the activation of signaling pathways. In vitro, the interaction between peripheral blood mononuclear cells (PBMCs) and C3H10T1/2 cells was investigated via cell coculture experiments.
Results:
RasGRP4 decreased the expression of hypoxia-inducible factor 2-alpha (HIF2A) via the ubiquitination–proteasome degradation pathway and promoted myofibroblastic transformation by activating critical inflammatory pathways, consequently reducing the production of EPO in T2DM mice.
Conclusion
RasGRP4 participates in the production of renal EPO in diabetic mice by affecting the secretion of proinflammatory cytokines in PBMCs, degrading HIF2A, and promoting the myofibroblastic transformation of C3H10T1/2 cells.

To summarize the clinical experience of Professor LIU Jinmin in treatment for epilepsy. It is believed that main pathogenesis of epilepsy is yangming failure to close and vital activity loss control, so a therapeutic approach focused on restoring the closure of yangming and regaining vital activity was proposed for the treatment of epilepsy. For excess syndrome, the treatment focuses on draining excess and descending qi, promoting purgation and restoring spirit. When yangming dryness-heat predominates, the approach involves unblock the bowels and regulating the spirit, descending qi and reducing fire, with modified Chengqi Decoction (承气汤) as prescription; when yangming phlegm-fire predominates, the treatment focuses on clearing heat and resolving phlegm, calming mind and suppressing fright, with modified Qingxin Wendan Decoction (清心温胆汤) as prescription; when yangming blood stasis predominates, the approach involves breaking up blood stasis and promoting purgation, eliminating stasis and awakening the mind, with Taoren Chengqi Decoction (桃核承气汤) as prescription. For deficiency syndrome, the treatment emphasizes tonifying deficiency and raising qi, strengthening the stomach and nourishing the spirit. When center qi deficiency and sinking of clear qi of the nutrients from food, the approach involves replenishing and uplifting qi while nourishing vital activity, with modified Liujunzi Decoction (六君子汤) as prescription; when yin deficiency and fluid consumption, the treatment focuses on nourishing stomach and tonifying yin, promoting fluid production and calming the spirit, with modified Maimendong Decoction (麦门冬汤) combined with Yiwei Decoction (益胃汤) as prescriptions. In clinical situations of deficiency-excess complex, it is essential to distinguish the primary condition from the secondary, applying both supplementing and draining methods flexibly to achieve optimal treatment.

OBJECTIVE To establish the precise management model for the centralized preparation of cytotoxic drugs in pharmacy intravenous admixture services (PIVAS), and evaluate the effects of its application. METHODS Pharmacists in PIVAS established the precise management model by soliciting clinical opinions and consulting literature on the centralized preparation of cytotoxic drugs and continuously refining every step of the preparation of cytotoxic drugs, based on data feedback from the information closed-loop management system and the limit of stability time of finished solutions. The indicators such as the preparation time, delivery time, the storage time of finished infusion solutions after preparation, and the completion rate of infusion within the stability time limit were analyzed before the implementation (January to December 2023) and after the implementation (January to December 2024) of this model, to evaluate its application effectiveness. RESULTS The overall framework for the precise management model included upgrading the functions of the prescription review system, improving the prescription review database, providing specialized training for PIVAS pharmacists, managing dynamic batch decision for drug preparation, managing special drugs, managing finished infusion distribution, and establishing a continuous improvement mechanism. Compared with before implementation, the average preparation time of the second and third batches of cytotoxic drugs with more concentrated morning preparation tasks in this model was significantly shorter than before implementation (P<0.05); the delivery time of finished infusion after implementation ([ 11.49±2.92) min] was significantly shorter than the delivery time before implementation ([ 22.11±5.03) min] (P<0.001); the storage time of some drugs with shorter stable time limit and carboplatin in combination regimens (paclitaxel or docetaxel+carboplatin) was significantly shortened compared to before implementation (P<0.05), and the completion rate of infusion within the stability time limit was significantly improved compared to before implementation (P<0.05). CONCLUSIONS Our hospital has successfully established a precise management model for the centralized preparation of cytotoxic drugs in PIVAS. This mode can significantly shorten the preparation time of each batch of PIVAS in the morning, make batch decisions more reasonable and improve the infusion completion rate within the stable time limit of the finished product.

Glucagon-like peptide-1 (GLP-1) receptor agonists are a novel class of antidiabetic drugs that also possess lipid- lowering and cardiovascular protective effects, with liraglutide and semaglutide being their representative medications. Based on a systematic literature search, this review summarizes the lipid-lowering mechanisms by which liraglutide and semaglutide exert direct effects on the liver and kidney (regulating autophagy, key lipid metabolism pathways, reverse cholesterol transport, etc.), direct actions on adipose tissue (affecting adipocyte proliferation and differentiation, expression of lipid metabolism proteins, and gene transcription), activation of sympathetic pathways through the central nervous system, and modulation of the gut microbiota. Additionally, it summarizes the clinical evidence of their lipid-lowering effects in populations with type 2 diabetes mellitus, overweight individuals, and others. These findings indicate that GLP-1 receptor agonists exert lipid-lowering effects by acting on multiple tissues or systems, providing crucial evidence for further elucidating the molecular mechanisms of these drugs in lipid regulation and exploring potential new ideas for their clinical applications.
