ObjectiveHistorically documented Zhejiang Atractylodis Macrocephalae Rhizoma(Baizhu) possesses premium characteristics such as phoenix-like head and crane-like neck, pronounced sweetness, and fragrant aroma. However, its current market circulation is low, and the processed products with Zhejiang-style characteristics are at the risk of being lost. This study aims to preserve the ancient Zhejiang-style processing techniques and evaluate them using modern scientific methods. MethodsMultidimensional intelligent sensory evaluation was used to digitally characterize the "quality-structure" of the external appearance of nine-steamed and nine-processed Baizhu medicinal materials(intermediate processed products) and the "odor-taste" of the internal quality of its decoction pieces(slices), and the appearance parameters were digitally characterized by colorimeter, texture analyzer, electronic nose and electronic tongue, the chemical composition was analyzed via ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS). Then, cluster analysis on the differences in odor between the medicinal materials(intermediate processed products) and decoction pieces(slices) of nine-steamed and nine-processed Baizhu was conducted, as well as the differences in taste between water-soluble and alcohol-soluble extracts of the decoction pieces(slices), and the correlation analysis of chroma value-alcohol-soluble extract content-component response value. ResultsThe nine-steamed and nine-processed Baizhu had a dark brown to black epidermis, a brownish-yellow to brownish-gray cross-section, a slightly tough texture, a faint odor, and a slightly sweet, bitter and pungent taste. Texture analyzer measurements revealed minimal adhesion and maximum recovery in the middle section of the characteristic processed Baizhu, consistent with the processing endpoint of thorough steaming and cooking. The head section showed the highest internal hardness, elasticity and chewiness, indicating a denser texture in this area. The electronic nose sensor could clearly distinguish the difference between the medicinal materials and its decoction pieces, with a more significant clustering effect at 60 ℃ for 30 minutes compared to ambient temperature headspace for 2 hours, highlighting the significant impact of the baking degree before slicing on the quality. The electronic tongue taste signal map clearly distinguished the differences between water-soluble and alcohol-soluble extracts of nine-steamed and nine-processed Baizhu decoction pieces, and the addition of auxiliary materials during processing could enhance its alcohol-soluble extract content. A total of 82 chemical components were identified in the characteristic processed Baizhu. After processing, the contents of 58 components increased, while 24 components decreased. Correlation analysis revealed significant negative correlations(P<0.01) between ethanol-soluble extract content and colorimetric values of brightness(L*), yellow-bule value(b*), and total color difference(E*ab). E*ab showed marked negative correlations(P<0.05) with the response values of isochlorogenic acid A and C. ConclusionThis study establishes a modern intelligent sensory evaluation model for multidimensional holographic characterization of nine-steamed and nine-processed Baizhu, clarifying the correlation between increased isochlorogenic acid content and the visual color appearance after different steaming cycles, as well as its intrinsic alcohol-soluble extracts. This provides a reference for quality evaluation and processing standards of the Zhejiang-style characteristic processed products.

Despite therapy with potent antiviral agents, chronic hepatitis B (CHB) patients remain at high risk of hepatocellular carcinoma (HCC). While metabolites have been rediscovered as active drivers of biological processes including carcinogenesis, the specific metabolites modulating HCC risk in CHB patients are largely unknown. Here, we demonstrate that baseline plasma from CHB patients who later developed HCC during follow-up exhibits growth-promoting properties in a case-control design nested within a large-scale, prospective cohort. Metabolomics analysis reveals a reduction in long-chain acylcarnitines (LCACs) in the baseline plasma of patients with HCC development. LCACs preferentially inhibit the proliferation of HCC cells in vitro at a physiological concentration and prevent the occurrence of HCC in vivo without hepatorenal toxicity. Uptake and metabolism of circulating LCACs increase the intracellular level of acetyl coenzyme A, which upregulates histone H3 Lys14 acetylation at the promoter region of KLF6 gene and thereby activates KLF6/p21 pathway. Indeed, blocking LCAC metabolism attenuates the difference in KLF6/p21 expression induced by baseline plasma of HCC/non-HCC patients. The deficiency of circulating LCACs represents a driver of HCC in CHB patients with viral control. These insights provide a promising direction for developing therapeutic strategies to reduce HCC risk further in the antiviral era.

Advanced atherosclerosis is the major global cause of death, as featured by the aggregation of apoptotic cells (ACs) in necrotic cores. The defective efferocytosis and dysfunctional cholesterol efflux of macrophages are the main reasons for forming necrotic cores in advanced atherosclerosis. In this study, we constructed self-assembled procyanidins (PC) NPs for loading pitavastatin (Pita). The designed HA@PC@Pita NPs with hyaluronic acid (HA) modification combined the advantages of efferocytosis restoration of Pita and cholesterol efflux enhancement of PC. In vitro assay indicated that HA@PC@Pita NPs could induce M1/M2 repolarization and upregulate ERK5/Mertk expression to restore efferocytosis of macrophages. Simultaneously, HA@PC@Pita NPs notably promoted cholesterol efflux by promoting macrophage lipophagy, a selective autophagy of lipid droplets. In vivo study showed that HA@PC@Pita NPs cleared necrotic core and enhanced plaque stability in the ApoE -/- mice model with advanced atherosclerosis. Taken together, this study demonstrated the potential of HA@PC@Pita NPs for the treatment of advanced atherosclerosis.

The diagnosis of hematological disorders is currently established from the combined results of different tests, including those assessing morphology (M), immunophenotype (I), cytogenetics (C), and molecular biology (M) (collectively known as the MICM classification). In this workflow, most of the results are interpreted manually (i.e., by a human, without automation), which is expertise-dependent, labor-intensive, time-consuming, and with inherent interobserver variability. Also, with advances in instruments and technologies, the data is gaining higher dimensionality and throughput, making additional challenges for manual analysis. Recently, artificial intelligence (AI) has emerged as a promising tool in clinical hematology to ensure timely diagnosis, precise risk stratification, and treatment success. In this review, we summarize the current advances, limitations, and challenges of AI models and raise potential strategies for improving their performance in each sector of the MICM pipeline. Finally, we share perspectives, highlight future directions, and call for extensive interdisciplinary cooperation to perfect AI with wise human-level strategies and promote its integration into the clinical workflow.

OBJECTIVES:
To investigate the effects of quercetin on cuproptosis and L-type calcium currents in the myocardium of diabetic rats.
METHODS:
Forty SD rats were randomized into control group and diabetic model groups. The rat models of diabetes mellitus (DM) induced by high-fat and high-sugar diet combined with streptozotocin (STZ) injection were further divided into DM model group, quercetin treatment group, and empagliflozin treatment group (n=10). Blood glucose and body weight were measured every other week, and cardiac function of the rats was evaluated using echocardiography. HE staining, Sirius red staining, and wheat germ agglutinin (WGA) analysis were used to observe the changes in myocardial histomorphology, and serum copper levels and myocardial FDX1 expression were detected. In cultured rat cardiomyocyte H9c2 cells with high-glucose exposure, the effects of quercetin and elesclomol, alone or in combination, on intracellular CK-MB and LDH levels and FDX1 expression were assessed, and the changes in L-type calcium currents were analyzed using patch-clamp technique.
RESULTS:
The diabetic rats exhibited elevated blood glucose, reduced body weight, impaired left ventricular function, increased serum copper levels and myocardial FDX1 expression, decreased L-type calcium currents, and prolonged action potential duration. Quercetin and empagliflozin treatment significantly lowered blood glucose, improved body weight, and restored cardiac function of the diabetic rats, and compared with empagliflozin, quercetin more effectively reduced serum copper levels, downregulated FDX1 expression, and enhanced myocardial L-type calcium currents in diabetic rats. In H9c2 cells, high glucose exposure significantly increased myocardial expressions of FDX1, CK-MB and LDH, which were effectively lowered by quercetin treatment; Elesclomol further elevated FDX1, CK-MB and LDH levels in the exposed cells, and these changes were not significantly affected by the application of quercetin.
CONCLUSIONS
Quercetin ameliorates myocardial injury in diabetic rats possibly by suppressing myocardial cuproptosis signaling and restoring L-type calcium channel activity.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

OBJECTIVE To know about the working mode and human resource status of pharmacy intravenous admixture services (PIVAS) in national medical institutions. METHODS Through questionnaire survey, the national PIVAS was invited to fill out questionnaire and statistical analysis was performed on the effective sample data related to PIVAS working mode and human resources in the questionnaire. RESULTS In this study, 761 PIVAS from 722 medical institutions of 29 provinces were involved in the questionnaire survey, with 471 valid questionnaires for working mode and 441 valid questionnaires for human resources survey. In terms of working mode, among 471 PIVAS, 292 PIVAS (62.0%) were in pharmacist-alone mode, and 176 PIVAS (37.4%) were in pharmacist-nurse cooperative mode; there was no significant difference in the types of medical orders received by PIVAS between these two working modes except for the other medical orders (P>0.05). In terms of human resource setting, among 441 PIVAS, the average number of total staff of single PIVAS was 24(16,33), including 11(6,19) pharmacists, 7(2,13) nursing staff, and 3(1,5) workers; there was a statistically significant difference in the number of personnel among three groups (P< 0.01). The per capita income of PIVAS respondents in 2019 was [7.9(4.8,10.7)]×104 yuan, and in 2021 it was [8.8(5.8,11.7)]× 104 yuan, with an increase of 9.0% compared to 2019. The difference between the two groups was statistically significant (P< 0.01). CONCLUSIONS Medical institutions’ PIVAS in China had not fully implemented the pharmacist-alone work model, and some medical institutions had chosen a pharmacist-nurse cooperative mode. It is suggested that relevant departments formulate corresponding qualification requirements and training standards for nursing personnel as soon as possible based on sufficient research on PIVAS’s demand for nursing professionals.

OBJECTIVE To know about the pharmacy intravenous admixture charge and operation balance of pharmacy intravenous admixture services (PIVAS) in national medical institutions. METHODS Using questionnaire survey method, the national PIVAS leaders were invited to fill in the questionnaire, investigation and statistical analysis of the drug dispensing charge standard and the income and expenditure situations of PIVAS nationwide were conducted. RESULTS A total of 761 PIVAS completed the questionnaire, among which 466 PIVAS (61.2%) had already started implementing pharmacy intravenous admixture charge, mainly in tertiary hospitals. The charge standards for chemotherapy drugs and parenteral nutrition solutions were relatively high, while the standards for packaged drugs were the lowest, with differences in charge standards among provinces(P<0.05). Among the 25 provinces that reported annual drug preparation fee revenue, Hubei had the highest revenue in both 2019 and 2021. In 2019, the number of PIVAS with a balance of payments was more than that of PIVAS with an imbalance of payments, but the number of PIVAS with an imbalance of payments in 2021 exceeded the number of PIVAS with a balance of payments (P<0.05); among them, eight provinces were unbalanced in 2019 and 2021, such as Tianjin, Chongqing, Guizhou, etc. CONCLUSIONS PIVAS charge standards of the surveyed medical institutions in all provinces are not unified. It is suggested to improve the charge standard further, formulate the charge adjustment cycle, and promote a sustainable development of PIVAS.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.
