Differences in chemical components in processing of dried ginger-steamed, sand-fried, and rice swill water-bleached Aconiti Lateralis Radix Praeparata pieces in "Jianchang" faction based on UPLC-MS/MS / 中国中药杂志

This study compared the changes in chemical components during the processing of different types of Aconiti Lateralis Radix Praeparata(ALRP) in "Jianchang" faction, i.e., dried ginger-steamed ALRP pieces(Yin-FP), sand-fried ALRP pieces(Yang-FP), and rice swill water-bleached ALRP pieces(DFP), and provided a scientific basis for the mechanism in toxicity reduction and efficacy enhancement from a compositional perspective. Samples were collected during the processing of the three types of ALRP pieces, yielding raw ALRP pieces, water-bleached Yin-FP, ginger juice-moistened Yin-FP, steamed Yin-FP, water-bleached Yang-FP, sand-fried Yang-FP, water-bleached DFP, rice swill water-bleached DFP, and roasted DFP. Aconitine, mesaconitine, hypaconitine, benzoylaconine, benzoylmesaconine, benzoylhypaconine, aconine, mesaconine, hypaconine, salsolinol, fuziline, and higenamine in the extracts were determined by UPLC-MS/MS, and then content analysis and cluster heatmap analysis were performed on 11 sets of samples. During the processing of the three types of ALRP pieces, bleaching significantly reduced the content of 12 alkaloids; steaming, stir-frying, and roasting significantly reduced the content of diester-type alkaloids(aconitine, mesaconitine, and hypaconitine) and significantly increased the content of monoester-type alkaloids(benzoylaconine, benzoylmesaconine, and benzoylhypaconine) and aminoalcohol-type alkaloids(aconine, mesaconine, and hypaconine). During the processing of Yin-FP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. During the processing of Yin-FP, Yang-FP, and DFP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. Steamed Yin-FP showed a higher increase in content than fried Yang-FP and roasted DFP. Comprehensive analysis of content differences in toxic and therapeutic components in three ALRP pieces suggests that the distinctive processing methods in "Jianchang" faction can indeed achieve detoxification and efficacy enhancement on ALRP. This study provides references for understanding the mechanisms of action of the three processing methods.

Objective: To investigate the clinical characteristics, cytogenetics, molecular biology, treatment, and prognosis of patients with therapy-related myelodysplastic syndrome and acute myeloid leukemia (t-MDS/AML) secondary to malignancies. Methods: The clinical data of 86 patients with t-MDS/AML in West China Hospital of Sichuan University between January 2010 and April 2023 were retrospectively analyzed. The clinical characteristics, primary tumor types, and tumor-related therapies were analyzed. Results: The study enrolled a total of 86 patients with t-MDS/AML, including 67 patients with t-AML, including 1 patient with M(0), 6 with M(1), 27 with M(2), 9 with M(3), 12 with M(4), 10 with M(5), 1 with M(6), and 1 with M(7). Sixty-two patients could be genetically stratified, with a median overall survival (OS) of 36 (95% CI 22-52) months for 20 (29.9%) patients in the low-risk group and 6 (95% CI 3-9) months for 10 (14.9%) in the intermediate-risk group. The median OS time was 8 (95% CI 1-15) months in 32 (47.8%) patients in the high-risk group. For patients with non-acute promyelocytic leukemia (APL) and AML, the median OS of the low-risk group was 27 (95% CI 18-36) months, which was significantly longer than that of the non-low-risk group (χ(2)=5.534, P=0.019). All 9 APL cases were treated according to the initial treatment, and the median OS was not reached, and the 1-, 2-, and 3-year OS rates were 100.0%, (75.0±6.2) %, and (75.0±6.2) % respectively. Of the 58 patients with non-APL t-AML (89.7%), 52 received chemotherapy, and 16 achieved complete remission (30.8%) after the first induction chemotherapy. The 1-, 2-, and 3-year OS rates of the non-APL t-AML group were (42.0 ± 6.6) %, (22.9±5.7) %, and (13.4±4.7) %, respectively. The median OS of patients who achieved remission was 24 (95% CI 18-30) months, and the median OS of those who did not achieve remission was 6 (95% CI 3-9) months (χ(2)=10.170, P=0.001). Bone marrow CR was achieved in 7 (53.8%) of 13 patients treated with vineclar-containing chemotherapy, with a median OS of 12 (95% CI 9-15) months, which was not significantly different from that of vineclar-containing chemotherapy (χ(2)=0.600, P=0.437). In 19 patients with t-MDS, the 1-, 2-, and 3-year OS rates were (46.8±11.6) %, (17.5±9.1) %, and (11.7±9.1) % with a median OS of 12 (95% CI 7-17) months, which was not significantly different from that in t-AML (χ(2)=0.232, P=0.630) . Conclusions: Breast cancer, bowel cancer, and other primary tumors are common in patients with t-MDS/AML, which have a higher risk of adverse genetics. Patients with APL had a high induction remission rate and a good long-term prognosis, whereas patients without APL had a low remission rate and a poor long-term prognosis.

Multi-omics approaches for revealing the etiology of cancer: from genomics, exposomics, metabolomics to system epidemiology / 中华流行病学杂志

Identifying risk factors of the disease are one of the main tasks of epidemiology. With the advancement of omics technologies (e.g., genome, transcriptome, proteome, metabolome, and exposome), cancer etiology research has entered the stage of systems epidemiology. Genomic research identifies cancer susceptibility loci and uncovers their biological mechanisms. Exposomic research investigates the impact of environmental factors on biological processes and disease risks. The metabolome is downstream of biological regulatory networks, reflecting the effects of the gene, environment, and their interactions, which can help elucidate the biological mechanisms of genetic and environmental risk factors and identify new biomarkers. Here, we reviewed the applications of genomic, exposomic, and metabolomic studies in the etiologic research on cancer. We summarized the importance of multi-omics approaches and systems epidemiology in cancer etiology research and outlined future perspectives.

Influencing Factors Regulating the Expression of the Macrophage Migration Inhibitor Factor (MIF) Gene / 中国生物化学与分子生物学报

Macrophage migration inhibitory factor (MIF) is a widely expressed multipotent cytokine that participates and plays an important role in various inflammatory and immune diseases‚ and is a biomarker or therapeutic target of many diseases. MIF is highly conserved in phylogeny and there are specific binding sites of various transcription factors in its promoter region‚ which can regulate the expression of MIF. MIF functions both inside and outside cells‚ and MIF is constitutively expressed. Therefore‚ it is of great significance to study the related factors that regulate MIF gene expression and stimulate MIF secretion. This article summarizes and classifies the related factors affecting MIF gene expression by briefly describing the binding sites on the MIF gene and MIF promoter. According to the way of binding with the MIF gene‚ it can be divided into:(1) binding to specific sites of MIF gene promoters to change transcription activity; (2) binding to MIF CATT5-8 microsatellite repeats to change highly expressed MIF alleles (3) non-coding RNAs regulating MIF expression; (4) related factors affecting MIF secretion. By reviewing the four types of related factors that regulate MIF gene expression‚ we will understand the regulatory mechanism and influencing factors of MIF gene expression‚ in order to provide a theoretical basis for its treatment of related diseases.

The variation of serum uric acid levels among patients with myocardial infarction treated with ticagrelor and the association between serum uric acid and platelet reactivity / 中华心血管病杂志

Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) μmol/L vs. (94.4±43.9) μmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) μmol/L vs. 7.8 (-2.0, 16.6) μmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

The safety and efficacy of Firesorb bioresorbable scaffold in first-in-man study for coronary artery disease: the four-year outcomes / 中华心血管病杂志

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Objective: To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage (tuina) in treating infantile diarrhea due to spleen deficiency. Methods: Ninety infants were randomly divided into a massage plus moxibustion group, a massage group and a drug group by the random number table method, with 30 cases in each group. The intervention was conducted for two consecutive courses. The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque (CV 8). The infants in the massage group were treated with pediatric massage alone, while those in the drug group were treated with smecta. The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups, and the total effective rate was evaluated after treatment. Results: The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group (both P<0.05). After treatment, the scores of primary and secondary symptoms decreased in all three groups, with statistically significant intra-group differences (all P<0.05); the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group (P<0.05); the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group (both P<0.05). The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant (P>0.05). Conclusion: Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency, and has the advantages of appetite improvement, physique strengthening and short course.

Pharmacodynamic material basis and mechanism of Fufang Yuxingcao Mixture for the treatment of heat-clearing and detoxification based on network pharmacology / 药学学报

We explored the pharmacodynamic material basis and network regulatory mechanism of Fufang Yuxingcao Mixture (FYM) for the treatment of fever and inflammation. Targets of the 25 compounds in FYM were predicted according to the reverse pharmacophore method and TCMSP, UniProt database. Gene ontology (GO) function enrichment and pathway analysis of the targets was analyzed by Omicsbean software and the Kyoto Gene and Genome Encyclopedia (KEGG) database. A "compound-target-pathway-pharmacological action-effect" network was established with Cytoscape 3.6.1 software. The lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was used to verify the anti-inflammatory effects of FYM and its 10 important components. The network pharmacology experiment showed that 25 compounds affected 97 pathways through 211 targets, of which 15 key targets [including RAC-alpha serine/threonine-protein kinase (AKT1), insulin (INS), vascular endothelial growth factor A (VEGFA), interleukin-6 (IL-6), cellular tumor antigen p53 (TP53), tumor necrosis factor (TNF), transcription factor AP-1 (JUN), caspase-3 (CASP3), matrix metalloproteinase-9 (MMP9), interleukin-8 (IL-8), prostaglandin G/H synthase 2 (PTGS2), proto-oncogene c-Fos (FOS), tyrosine-protein kinase SRC (SRC), c-Jun N-terminal kinase 1 (MAPK8), estrogen receptor 1 (ESR1)] and 46 pathways (including NF-kappa B signaling pathway, Toll-like receptor signaling pathway, MAPK signaling pathway, IL-17 signaling pathway, arachidonic acid metabolism, cAMP signaling pathway, T cell receptor signaling pathway, calcium signaling pathway, inflammatory mediator regulation of TRP channels, chemokine signaling pathway, Th1 and Th2 cell differentiation, natural killer cell mediated cytotoxicity, etc.) were related to anti-inflammatory, antipyretic, immune regulation, and analgesia. In vitro cell experiments showed that FYM and the 10 components (including isoquercitrin, luteoloside, baicalein, wogonin, wogonoside, phillyrin, forsythoside A, chlorogenic acid, isochlorogenic acid A, and sweroside) could significantly reduce the expression of nitric oxide (NO), TNF-α and IL-6 in cell supernatants, indicating that the above 10 components may be the key pharmacodynamic material basis of FYM.

Ethnobotanical study of Juenang cultural area in Rangtang county of northwestern Sichuan / 中国中药杂志

Indigenous knowledge and traditional culture for sustainable use of native plants in Juenang cultural region of Rangtang county, Aba Zang and Qiang Prefecture of Sichuan province, have been characterized in this paper followed the principles and methods of ethnobotany. The results indicate that 38 species from 27 families(including 6 species of fungi) are ethnobotanically used commonly in this area. Of 38 species of the native plants, 13 species from 12 families are collected for eatables and vegetables, 12 families and 16 species of indigenous plants for medicinal and edible use, 4 species from 4 families for decoration, 4 species from 4 families used for building materials or firewood, and 1 species from 1 families used for religious folklore. Under the influence of Juenang culture and Tibetan culture, indigenous knowledge such as instinctive reverence and gratitude for nature, protection ecological environment and habitats, and moderate use of natural resources(especially wild bioresource), have been gotten passed on from generation to generation in Juenang culture region of Rangtang county, which is of great significance to the protection of local bioresources and environment, including ethnic medicinal plants, and also to provide practical guidance for biodiversity conservation and ecological restoration in those alpine ecological vulnerable areas.

Associations between postprocedural D-dimer, hs-CRP, LDL-C levels and prognosis of acute myocardial infarction patients treated by percutaneous coronary intervention / 中华心血管病杂志

Objective: To investigate the association between postprocedural D-dimer, high sensitivity C-reactive protein(hs-CRP) and low-density lipoprotein-cholesterol(LDL-C) and outcomes of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention(PCI), in order to clarify the impacts of thrombotic, inflammatory and cholesterol risks on long-term prognosis. Methods: Patients with AMI who underwent emergency PCI from January 2010 to June 2017 in Fuwai Hospital with complete baseline data were enrolled. Patients were stratified into four groups according to quartiles of D-dimer, hs-CRP and LCL-C. Cox regression was used to analyze the relationship between these biomarkers and prognosis. Restricted cubic spline (RCS) was used to characterize the continuous association between risk of all-cause death and biomarkers. The primary outcome was all-cause death. Results: A total of 3 614 patients were included in the analysis. The age was (59.2±12.0) years old, and 2 845 (78.7%) were male and 3 161 (87.5%) patients were diagnosed as ST-segment elevation myocardial infarction. The follow-up time was 652 (414, 1 880) days. Survival analysis showed that postprocedural D-dimer and hs-CRP were significantly associated with all-cause mortality (all P<0.05). Cox regression with multiple adjustments showed that patients with D-dimer≥580 μg/L presented higher risk of all-cause death (HR=2.03, 95%CI 1.22-3.38, P=0.006), compared to patients with D-dimer<220 μg/L. RCS analysis showed that risk of all-cause death was stably high when D-dimer reached 500 μg/L. Multivariable Cox regression also showed that patients with hs-CRP<2.74 mg/L (HR=1.86, 95%CI 1.10-3.15, P=0.020)or hs-CRP≥11.99 mg/L (HR=2.14, 95%CI 1.35-3.40, P=0.001) presented higher mortality compared to patients whose hs-CRP was 2.74-7.18 mg/L. RCS analysis indicated a J-shaped relation between hs-CRP and mortality, as greater risk of death was observed when hs-CRP was lower than 2 mg/L or higher than 10 mg/L. LDL-C was not associated with outcomes (all P>0.05). Conclusions: Postprocedural D-dimer is significantly associated with long-term prognosis of AMI patients treated by PCI. Patients with extremely high or low levels of hs-CRP presents worse outcomes. Intensive and tailored antithrombotic or anti-inflammatory therapies should be considered for patients with increased thrombotic risk and those with extremely high or low inflammatory risk.
