YANG Jinrun, LI Xiang, SUN Yang

2025, 43(5): 222-227. doi: 10.12206/j.issn.2097-2024.202410014

Objective To investigate the role and signaling pathway mechanism of Orosomucoid-1（ORM1）in hepatocyte proliferation. Methods The expression data of ORM1 after liver resection from the GEO database were analyzed. The effects of ORM1 on hepatocyte proliferation were assessed after overexpressing ORM1 or supplementing exogenous ORM1 in liver cells. Cell proliferation was evaluated by the CCK8 assay. RNA sequencing （RNA-seq） was performed on liver tissues from ORM1 knockout mice and wildtype littermates to analyze gene expression, and KEGG enrichment analysis was employed to explore the molecular mechanisms by which ORM1 regulates hepatocyte proliferation. Results After partial liver resection in mice, ORM1 expression increased during the liver regeneration process. In vitro, ORM1 promoted the proliferation of murine Hepa1-6 hepatocytes and human HepG2 hepatocellular carcinoma cells. RNA-seq analysis of liver tissues from ORM1 knockout mice indicated that ORM1 influenced several proliferation-related pathways, including the PI3K-Akt, MAPK, Hippo, and Jak-Stat pathways. Upon ORM1 knockout, the expression of pro-proliferative genes such as Ctgf, Tcf7, Tead1, Il6ra, and Lepr decreased, while the expression of anti-proliferative genes such as Cish and Gadd45a increased. Conclusion ORM1 may promote hepatocyte proliferation by regulating key genes in cell proliferation-related pathways, including the PI3K-Akt, MAPK, Hippo and Jak-Stat pathways. More>>

FENG Yifan, YAN Xiaodong, ZHANG Wenbin, LI Bingfeng, et al

2025, 43(5): 228-234. doi: 10.12206/j.issn.2097-2024.202407038

Objective To explore the promoting effect of long-term administration of nicotiflorin on the recovery of neurological function in rats with cerebral ischemia-reperfusion injury （CIRI）. Methods The CIRI model was established and nicotiflorin was injected intraperitoneally after 1 hour of obstruction for 8 weeks. Tail suspension deflection experiment, balance beam experiment and water maze test were performed in the 2nd, 4th and 8th weeks. After 8 weeks, TTC staining was used to observe the volume of infarct atrophy, transcriptome sequencing was employed to screen differential expressed genes （DEGs） and highly enriched pathways were analyzed, Western-bloting and Elisa were used to assess proteins expression related to the pyroptosis pathway and inflammatory cytokines IL-1β and IL-18. Results By long-term administration of nicotiflorin, the contralateral deflection rate was significantly reduced and beam experiment score of CIRI rats was balanced, the number of crossing the platform in water maze test was increased （P<0.05）, the volume of cerebral infarction atrophy was decreased （P<0.01）, which significantly promoted the recovery of neurological function in rats. Transcriptome sequencing found that the expression of genes in the pyroptosis-related signaling pathways in the brain tissue of rats in the nicotiflorin group was significantly down-regulated （P<0.05）. Western-blot and Elisa experiments showed that nicotiflorin reduced the expression levels of Caspase-1 and GSDMD-N and other pyroptosis-related proteins, and at the same time, the release of inflammatory factors IL-1β and IL-18 was significantly reduced （P<0.05）, indicating that nicotiflorin could inhibit the inflammatory process of pyroptosis. Conclusion Nicotiflorin exhibited a significant long-term promotion effect on the recovery of neurological function in CIRI rats, which potentially attributed from its ability to inhibit pyroptosis.

2025, 43(4): 180-184. doi: 10.12206/j.issn.2097-2024.202409055

Objective To investigate the effect of spontaneous hypertension on the remodeling of cardiac and aortic tissues in rats, with special attention to the changes in the content of collagen fibers, elastic fibers and secreted Frizzled-related protein 2 （sFRP2） in cardiac and aortic tissues. Methods 28-week-old SHR rats （Spontaneously Hypertensive rats） and WKY （Wistar-Kyoto rats） of the same age were selected as experimental animals. Cardiac load was assessed by calculating the cardiac weight index. Collagen fibers and elastic fibers were isolated from the rat thoracic aorta by hot alkali method, and their content was determined by biochemical analysis. In addition, pathological evaluation of tissue sections of the left ventricle and thoracic aorta were performed by H&E staining, Sirius red staining, and lichen red staining. Western blotting was used to determine the expression level of sFRP2 protein in cardiac tissues. Results Compared with WKY rats, the heart weight index of SHR rats increased significantly （P<0.001）, and the results of biochemical analysis and staining of pathological sections showed that the content of collagen fibers in the aorta in the SHR group was higher than that in the WKY group, while the content of elastic fibers was lower, but the difference did not have statistical significance. The content of collagen fibers in the heart of the SHR group was significantly higher than that in the WKY group （P<0.01）. Western blotting showed that there was no significant difference in the expression level of sFRP2 protein in heart tissues between the two groups. Conclusion The remodeling of cardiac and aortic tissues in a rat model of spontaneous hypertension may involve complex molecular mechanisms, not just changes in the content of collagen fibers and elastic fibers. The detailed mechanism of the progression of spontaneous hypertension and target organs damage still need further investigation. More>>

Design, synthesis and antifungal and antitumor activity research of novel Hsp90 inhibitors 新型Hsp90抑制剂的设计合成及其抗真菌和抗肿瘤活性研究

SHI Qiao, HAN Guiyan, ZHANG Junteng, LIU Na

2025, 43(3): 124-135. doi: 10.12206/j.issn.2097-2024.202501019

Objective To design and synthesize novel Hsp90 inhibitors with dual functions of synergistically enhancing the antifungal activity of fluconazole （FLC） against drug-resistant fungi and anti-tumor activity based on the Hsp90 inhibitor Ganetespib. Methods The previous research found that Ganetespib had a good synergistic anti-resistant fungal activity with FLC, with a fractional inhibitory concentration index （FICI） of 0.023 to 0.039. In this study, structural modifications were made to Ganetespib by replacing its indole ring with a phenyl ring containing different substituents to design and synthesize a series of new compounds. The in vitro synergistic anti-resistant fungal activity against C. albicans 0304103 in combination with FLC, anti-tumor activity （against HEL, HL60 and A549 cells）, and Hsp90α inhibition activity were determined to explore their structure-activity relationship and mechanism of action. Results The chemical structures of 19 new compounds were confirmed by ¹H NMR, ¹³C NMR and HRMS. Most of the compounds exhibited strong Hsp90α inhibitory activity, good synergistic activity against drug-resistant fungi in combination with FLC and anti-tumor activity. The substitution of electron-donating groups on the benzene ring was beneficial to enhancing the synergistic activity against drug-resistant fungi in combination with FLC. Among them, compounds F3 and F5 showed excellent synergistic activity against drug-resistant fungi in combination with FLC （FICI were both 0.047） and anti-tumor activity （IC₅₀ were 0.025 to 0.15 μmol/L and 0.021 to 0.23 μmol/L respectively）, and could down-regulate the expression levels of drug resistance genes and efflux pump genes in fungi, inhibit the formation of fungal biofilms, and arrest the cell cycle of HEL cells at G0/G1 phase. Conclusion The novel Hsp90 inhibitors such as F3 and F5 could both effectively exert the dual activities of synergizing with FLC to combat drug-resistant fungi and fight against tumors, which provided a new idea for the development of new drugs with dual functions of synergizing with FLC to combat drug-resistant fungi and fight against tumors.

In Press doi: 10.12206/j.issn.2097-2024.202409045

Abstract(7242) HTML(2899) PDF (3171KB)(29)

Abstract:
Objective To investigate the effect of activating α7 nicotinic acetylcholine receptor （α7nAChR） on calcium chloride （CaCl₂）-induced abdominal aortic aneurysm （AAA） injury in mice. Methods AAA model was induced by CaCl₂ in wild type （WT） mice and α7nAChR knockout （α7nAChR^−/-） mice. The effects of knockout of α7nAChR on histological damage in CaCl₂-induced AAA mice and expression of inflammatory factors were assessed by HE staining, EVG staining and IHC staining. Rat-derived primary vascular smooth muscle cells （VSMC） were stimulated with TNF-α, which mimicked the inflammatory environment of AAA. The expressions of inflammation-related proteins were detected by using Western-Blot with or without PNU-282987 to activate α7nAChR. Results Aortic dilatation was obvious, and the aortic structure was disrupted in CaCl₂-induced AAA mice. Knockout of α7nAChR further exacerbated the histological injury and significantly up-regulated the expression of inflammation-related proteins in aorta of AAA mice. It was showed that TNF-α stimulation of VSMC increased inflammation-related protein expression, whereas activation of α7nAChR prevented the phenomenon. Conclusion Activation of α7nAChR could attenuate CaCl₂-induced AAA injury in mice by suppressing the inflammatory response.

Objective To compare the contents of malonyl-ginsenosides Rb3 （MG-Rb3） in different parts, including roots, stems, leaves and flowers, of Panax ginseng, P. quinquefolium and P. notoginseng. To explore the effects of two drying methods, constant temperature drying and vacuum freeze drying on their contents. Methods The contents of MG-Rb3 in P. ginseng, P. quinquefolium and P. notoginseng were compared based on HPLC analysis, using enzymatically synthesized MG-Rb3 as the reference standard. Results The buds of P. ginseng and P. quinquefolium exhibited relatively high levels of MG-Rb3, which were approximately 7.3-18.1 times and 2.8-4.3 times higher than those found in the roots, respectively, and the lowest contents were detected in the stems. The content of MG-Rb3 in P. notoginseng flower buds was about 31.2 times higher than that in leaves. The content of MG-Rb3 in the buds treated by constant temperature drying was about 1-1.1 times that of using vacuum freeze drying. Conclusion The highest content of MG-Rb3 was detected in the flower buds of P. ginseng and P. notoginseng, and the content of MG-Rb3 in leaves of P. quinquefolium was the highest. Content of MG-Rb3 in the buds after constant temperature drying was slightly higher than that of using vacuum freeze drying.

Abstract:
Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg） by gavage, and the positive control drug atorvastatin calcium （1.5 mg/kg）. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.01]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by atorvastatin calcium. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in atorvastatin calcium group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduces the body weight of animals with high fat, reduce liver size, fat deposition, inflammatory damage and also significantly reduces blood lipid CHOL and LDL-C levels and reduce transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

Abstract:
Alzheimer’s disease （AD） is a typical neurodegenerative disorder, and its pathogenic mechanism remains to be fully elucidated. Currently, there are limited drugs available for the clinical treatment of AD, and many of these drugs are associated with numerous adverse effects. Traditional Chinese medicine （TCM）, featuring multi-component and multi-target properties, possesses unique advantages and potential in the prevention and treatment of AD. AD cell models enable in-depth investigations into the pathogenesis of AD and the mechanisms underlying drug-based prevention and treatment. Cell metabolomics studies changes in intracellular metabolites to accurately capture dynamic variations in metabolite types, contents, and metabolic pathways of cells under different physiological states; this approach holds promise for revealing the complex regulatory mechanisms of cellular metabolic networks, identifying AD-specific biomarkers, and providing support for research on the mechanisms of AD. This article reviews the drugs used for AD prevention and treatment, as well as recent progress in the application of cellular metabolomics in AD research, aiming to provide a reference for studies on AD mechanisms, clinical diagnosis and treatment, and drug development.

Abstract:
Objective To explore the application effect of a standardized management method based on failure mode and effect analysis （FMEA） in optimizing the whole-process quality control system of the intravenous admixture service （PIVAS）. Methods The quality control management system of the PIVAS was optimized by establishing six quality control groups led by the head nurse, with full participation of pharmacy, nursing, and logistical staff, ensuring comprehensive coverage and traceability of all quality control links. Each group conducted risk priority number （RPN） scoring for potential failure modes in their respective quality control processes, and targeted improvement measures were formulated based on the scoring results. The RPN values of failure modes and quality control-related evaluation indicators before and after implementation were compared to achieve closed-loop management. Results After one year of management, the RPN values of the six major failure modes significantly decreased compared to those before implementation （P<0.05）. The compounding error rate dropped to 0.13%, the dispensing error rate decreased to 0.95%, the compounding efficiency increased to 98%, the delivery time was shortened by 0.45 h per batch, the intervention rate for irrational prescriptions rose to 94.87%, satisfaction improved to 96.78%, and the participation rate of quality control personnel reached 95.36% （P<0.05）. Conclusion FMEA-based identification of potential failure modes in the whole-process quality control system of the IVAS, combined with risk quantification and targeted interventions, significantly reduces high-risk failure modes, improves compounding accuracy and efficiency, and ensures the safety of clinical intravenous medication and the effectiveness of healthcare quality management.

Abstract:
Objective To investigate the efficacy of aerobic exercise combined with sertraline in the treatment of post-stroke depression （PSD） in elderly patients and its effects on cognitive function and inflammatory cytokines. Methods 70 elderly PSD patients admitted to the Xuzhou Municipal Hospital affiliated with Xuzhou Medical University from June 2022 to December 2024 were selected as study objects. Patients were randomly divided into control group treated with sertraline and study group treated with aerobic exercise combined with sertraline. The treatment duration was 8 weeks. The Hamilton Depression Rating Scale （HAMD） scores, the clinical efficacy, cognitive function [Mini Mental State Examination （MMSE）], and the levels of inflammatory cytokines （IL-1β, IL-6, TNF-α） were compared before and after treatment. Results No significant differences in baseline data were observed between the two groups before treatment. After 4 and 8 weeks of treatment, HAMD scores were significantly decreased compared to baseline in both groups （all P<0.05）. The study group showed significantly lower HAMD scores than the control group at both 4 and 8 weeks （all P<0.05）. The overall clinical effective rate was significantly higher in the study group （94.29%） than in the control group （77.14%）（P<0.05）. MMSE scores were significantly increased compared to baseline in both groups at 4 and 8 weeks（all P<0.05）, and the study group demonstrated significantly higher MMSE scores than the control group at both time points （all P<0.05）. Similarly, serum levels of IL-1β, IL-6, and TNF-α were significantly reduced from baseline in both groups at 4 and 8 weeks （all P<0.05）. The reductions in these inflammatory cytokine levels were significantly greater in the study group compared to the control group （all P<0.05）. The incidence of adverse reactions was 8.57% in the control group and 5.71% in the study group, with no statistically significant difference （P>0.05）. Conclusion The combination of aerobic exercise and sertraline is a safe and reliable therapeutic strategy for elderly PSD patients, alleviating depressive symptoms, improving cognitive function, and reducing systemic inflammation.

Abstract:
Objective To investigate the efficacy and safety of EGFR-TKIs monotherapy and its combination therapy in the first-line treatment of advanced non-small cell lung cancer（NSCLC）patients with EGFR mutations. Methods Databases such as PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were systematically searched to collect eligible phase II/III randomized controlled trials （RCTs）, with the time range from the establishment of the databases to June 2023. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in the studies. Outcome data, including overall survival （OS）, progression-free survival （PFS）, objective response rate （ORR）, grade 3 or higher adverse events （≥3 AEs）, and serious adverse events （SAEs）, were collected. A network meta-analysis was performed using R software （version 4.2.1） under the Bayesian theoretical framework. Subgroup analyses of survival outcomes （OS, PFS） were conducted based on different clinical and pathophysiological characteristics of the patients. Results A total of t wenty-eight phase II/III RCTs were included in the study, involving a total of 7 460 patients and 18 first-line treatment regimens. The results showed that in terms of efficacy, gefitinib + pemetrexed-containing chemotherapy performed best in OS and ORR, while osimertinib + bevacizumab performed best in PFS. In terms of safety, furmonertinib had the lowest incidence of ≥3 grade AEs, and osimertinib had the lowest incidence of SAEs. Subgroup analysis results indicated that the efficacy and safety of various treatment regimens differed among patients with different clinical and pathological characteristics. Conclusion Monotherapy with third-generation EGFR-TKIs, represented by osimertinib, serves as the preferred therapeutic option considering both efficacy and safety profiles. While some combination therapies can enhance survival benefits, but need to be vigilant about increased toxicity. Clinical decision-making should be tailored based on patient' mutation subtypes, comorbidities, and tolerance.

Abstract:
This study aimed to clarify the causal relationship between meaning in life and depression symptoms, explore the evolutionary patterns of meaning in life, and assess its impact on the incidence of depressive symptoms. A two-wave longitudinal study with a 12-month interval was conducted among 896 university students recruited from one university. The meaning in life questionnaire and the depression symptom screening questionnaire were administered. The findings showed that: 1）Meaning in life at T1 negatively predicted depression symptoms at T2. Conversely, depression symptoms at T1 did not significantly predict meaning in life at T2. 2）The evolutionary patterns of meaning in life from T1 to T2 could be categorized into four groups: sustained low meaning, meaning improvement, meaning reduction, and sustained high meaning. The incidence of depressive symptoms in these four groups was 13.00%, 5.00%, 12.00%, and 4.00%, respectively. 3）The evolutionary patterns of meaning in life significantly impacted the incidence of depressive symptoms. Compared to the sustained high meaning group, both the sustained low meaning group and the meaning reduction group exhibited significantly higher rates of depression symptoms. The results suggest that psychological health education in universities should focus on individuals with sustained low meaning or meaning reduction, and that enhancing meaning in life serves as an effective intervention approach to reducing the incidence of depression symptoms among university students.

Abstract:
Objective The alkaloids contained in the Chinese herb Sophora flavescens have good anti-inflammatory activity. To investigate the structure-activity relationship between the novel Matrine and the anti-inflammatory activity by modifying the structure of Matrine . Methods Fourteen novel Matrine derivatives were obtained by chemical modification using Matrine as the lead compound with Matrine and M19 as positive controls. The cytotoxicity of Matrine derivatives against RAW264.7 cells was detected by the Cell Counting Kit 8 （CCK8） assay, and the relative amount of Nitric Oxide （NO） produced by Matrine derivatives against Lipopolysaccharide （LPS）-induced inflammation model of RAW264.7 cells was detected using an NO assay kit. The Enzyme-Linked Immunosorbent Assay （ELISA） d was used to detect the secretion of Interleukin-6 （IL-6） and Tumor Necrosis Factor Alpha （TNF-α） by Matrine derivatives in LPS-induced inflammation model of RAW264.7 cells. Results The novel Matrine derivatives all exhibited lower cytotoxicity compared with M19. The NO inhibition rates of the novel Matrine derivatives were all higher than that of Matrine, and some were higher than that of M19 , with compound A12 having the highest NO inhibition rate. Compounds A11 and A12 showed higher IL-6 inhibition than the control M19 . Additionally, compound A12 had higher TNF-α inhibition than the control M19 . Conclusion Compound A12 inhibited the strongest inhibition of NO, IL-6 and TNF-α release and had the best anti-inflammatory activity, which provided an important lead compound for this subsequent in-depth study.

Abstract:
Objective To investigate the preventive and therapeutic effects of ethanol extracts derived from three sources of traditional Chinese medicine: Stellera chamaejasme L., Euphorbia fischeriana Steud., and Euphorbia kansuensis Prokh., on imiquimod （IMQ）-induced psoriasis in mice. Methods Thirty-six male BALB/c mice were randomly divided into the following 6 groups with 6 mice in each group: blank control, model, Stellera chamaejasme, Euphorbia fischeriana, Euphorbia kansuensis, and calcipotriol. PASI （Psoriasis Area and Severity Index） scores were used to record the changes of skin lesions in each group; HE （hematoxylin-eosin） staining was used to observe the pathological morphology of skin and measure the thickness of the epidermis. Immunohistochemistry was used to detect the expression of nuclear antigen Ki67 in the skin tissues of mice. Results Compared with the model group, the three kinds of ethanol extracts can reduce the PASI score, inhibit epidermal thickening, and decrease expression of Ki67 in the psoriasis mice. Among them, the therapeutic effect of Stellera chamaejasme was the most significant and it was better than the commonly used topical drug calcipotriol. Conclusion The ethanol extract of Stellera chamaejasme has good anti-psoriatic activity, can inhibit the abnormal proliferation of keratinocytes, can reduce the expression of Ki67, and can significantly improve psoriasis-like skin lesions.
