Objective: The characteristics and differences of the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia were investigated to provide references and suggestions for the compilation of the Chinese Pharmacopoeia.
Methods: From the perspective of frame structure and main contents, the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia was compared.
Results: Each volume of the Chinese Pharmacopoeia had its general notice, including 34 to 48 items and 10 to 12 chapters based on different varieties collected in each volume. The Japanese Pharmacopoeia had 49 items not arranged by chapters. There are many differences on the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia, such as the definitions and expressions of names, determination of appearance, revision rules, risk assessment and quality control conception. The framework of the general notice in the Chinese Pharmacopoeia was clear, the content was specific and the operation was friendly. The term description of the general notice in the Japanese Pharmacopoeia was concise, and some terms need to be implemented under the guidance of professional knowledge.
Conclusion: In light of comparative study, every volume’s general notice of the Chinese Pharmacopoeia has its own characteristics. By integrating advanced analytical technique, combining the requirements with laws and regulations, and optimizing content and terms, all volume’s general notice could be explored to be coordinated and unified.

Objective To explore the feasibility and accuracy of neutrophil-to-lymphocyte ratio(NLR)in the prediction of testicular torsion(TT)in children with acute scrotal pain.Methods A retrospective case-control study was performed on 158 pediatric patients with ultrasound suspicion of TT who underwent surgical testicular examination during Jan.2017 and Jan.2024.The patients were divided into TT group and non-TT group.Clinical data and laboratory data at admission were analyzed.Sensitivity and specificity of NLR to TT were determined with the area under the curve(AUC)represented on the receiver operating characteristic(ROC)curves.Results There were with no statistically significant differences in clinical data between the two groups(P＞0.05).The NLR was significantly higher in the TT group than in the non-TT group[(4.82±2.37)vs.(2.85±0.75),P＜0.05].The optimal cut-off value of TT predicted by NLR was 2.07,the AUC was 0.809(95％CI:0.709-0.909),and the sensitivity and specificity were 97.9％and 93.3％,respectively,which were significantly higher than other factors.Conclusion For suspicious ultrasound diagnosis of pediatric acute scrotal pain cases,NLR can be used to predict the possibility of TT and may help to evaluate the urgent surgical treatment in these patients.

OBJECTIVE To investigate the mechanism by which Ginkgo flavone aglycone （GA） reduces the cardiotoxicity of doxorubicin （DOX） based on transcriptomics and proteomics. METHODS Thirty-six mice were randomly assigned to control group （CON group， tail vein injection of equal volume of physiological saline every other day+daily intragastric administration of an equal volume of physiological saline）， DOX group （tail vein injection of 3 mg/kg DOX every other day）， and GDOX group （daily intragastric administration of 100 mg/kg GA+tail vein injection of 3 mg/kg DOX every other day）， with 12 mice in each group. The administration of drugs/physiological saline was continued for 15 days. Mouse heart tissues were collected for RNA-Seq transcriptomic sequencing and 4D-Label-free quantitative proteomic analysis to screen differentially expressed genes and proteins， which were then subjected to Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. The expression levels of Apelin peptide （Apelin）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） mRNA and protein in mouse heart tissues， as well as the phosphorylation levels of PI3K and Akt proteins， were verified. H9c2 cardiomyocytes were divided into control group （CON group）， DOX group （2 μmol/L）， and GDOX group （2 μg/mL GA+2 μmol/L DOX） to determine cell viability and the levels of key glycolytic substances in the cells. RESULTS Six common pathways were identified from transcriptomics and proteomics， including the Apelin signaling pathway， the PI3K-Akt signaling pathway， and insulin resistance. Among them， the Apelin and PI3K-Akt signaling pathways were the most enriched in terms of gene numbers. Target validation experiments showed that compared to the CON group， the relative expression of Apelin， PI3K and Akt mRNA and protein levels， as well as the phosphorylation levels of PI3K and Akt proteins， were significantly decreased in the DOX group （P＜0.05 or P＜0.01）. The relative expression of Apelin， PI3K and Akt mRNA and the phosphorylation levels of PI3K and Akt proteins were significantly increased in the GDOX group as compared with the DOX group （P＜0.05 or P＜0.01）. Cellular experiments indicated that compared to the CON group， cell viability in the DOX group was significantly decreased （P＜0.05）， the relative uptake of glucose and the relative production of pyruvate and lactate were significantly increased （P＜0.05）， and the relative production of ATP was significantly reduced （P＜0.05）. Compared to the DOX group， cell viability in the GDOX group was significantly increased （P＜ 0.05）， and the relative production of pyruvate and lactate was significantly reduced （P＜0.05）. CONCLUSIONS GA may alleviate DOX-induced cardiotoxicity by upregulating the mRNA and protein expression of Apelin， PI3K， and Akt in heart tissues， and regulating glycolytic processes.

Objective To investigate the changes and clinical significance of plasminogen activator inhibi-tor-1(PAI-1),transforming growth factor-β(TGF-β),vascular endothelial growth factor(VEGF),and inter-leukin-6(IL-6)in patients with tuberculous pleurisy and pleural fibrosis.Methods A total of 103 patients with tuberculous pleurisy and pleural fibrosis who were treated in a hospital from July 2020 to July 2023 were selected as the research subjects.After 2 weeks of treatment,they were divided into a significant effect group and a non-significant effect group based on the therapeutic efficacy of glucocorticoid treatment.The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion were compared before treatment,after 1 and 2 weeks of treatment.The correlation between the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion and the therapeutic efficacy was analyzed by Spearman correlation analysis.Pearson correlation analy-sis was used to analyze the correlation between the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleu-ral effusion and the levels of these indicators in pleural effusion after 2 weeks of treatment.A receiver operat-ing characteristic curve was drawn to analyze the predictive value of the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion for the efficacy of tuberculous pleurisy and pleural fibrosis patients after 1 and 2 weeks of treatment.Results The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment in both groups were lower than those before treatment,and the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment in the significant effect group were lower than those in the non-significant effect group,with statistically significant differences(P＜0.05).The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment were negatively correlated with the efficacy(P＜0.05).The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 2 weeks of treatment were positively correlated(r=0.761,0.783,0.812,0.741,all P＜0.05).The area under the curve(AUC)of combined detection of serum and pleural effusion in-dicators after 1 and 2 weeks of treatment was greater than the AUC of individual indicators(P＜0.05).Con-clusion The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion of patients with tubercu-lous pleurisy and pleural fibrosis are related to the efficacy of treatment.The combined detection of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion has good predictive value and can provide reference for clinical intervention.

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 explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.
