OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger， and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content， total ash， and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides， including 14 flavonoids， 15 iridoids， 10 organic acids， 2 alkaloids and 8 other compounds. Among them， 42 components were detected in raw G. jasminoides， 28 in ginger-processed G. jasminoides， and 21 components were common to both. After processing with ginger， raw G. jasminoides lost 21 components （including iridoids， flavonoids， alkaloids， and others）， while 7 chemical components were added （including coumarins， organic acids， organic acid esters， and flavonoids）. For the 15 batches of ginger-processed G. jasminoides， the water content ranged from 5.64% to 7.11%， total ash from 2.92% to 4.87%， and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ were 0.108 7， 0.542 2， 0.565 0， and 0.012 5 mg/g， respectively. CONCLUSIONS After processing with ginger， G. jasminoides loses 21 components， while 7 new components are added. Differences are observed in the water content， total ash， ethanol-soluble extract， and the contents of genipin gentiobioside， geniposide， crocin Ⅰ， and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably， samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract， while samples from Jiangxi have a high content of crocin Ⅰ.

Objective:To examine attentional bias and its characteristics of college students with different lev-els of self-esteem toward cyber-aggressive information versus cyber-neutral information in frustration situations.Methods:Totally 280 college students were selected,and 76 subjects in the high self-esteem group(27％of the top SES scores)and 76 subjects in the low self-esteem group(27％of the bottom SES scores)were screened with the Self-Esteem Scale(SES).A virtual intelligence test was used to manipulate the frustration situation,and two groups were subjected to a situation initiation with and without frustration,and completed a point-probe task to examine the attentional vigilance and attentional extrication difficulty components of the attentional bias of college students with high and low self-esteem in frustration situations.Results:In the frustration context,low self-esteem college students had shorter response times to cyber-aggressive words than to cyber-neutral words(P＜0.001),low self-esteem college students' attentional vigilance scores to cyber-aggressive words weregreaterthan0(P＜0.001),and there was no statistically significant difference in the scores of attentional dissociative difficulties to cyber-ag-gressive words between high and low self-esteem college students compared to 0(Ps＞0.05).Conclusion:Low self-esteem college students in frustration situations have a significant attentional bias toward cyber-aggressive infor-mation,mainly in the form of attentional vigilance.

Objective:To evaluate the long-term outcomes and predictors of coronary atherosclerotic lesions deemed functionally non-ischemic (quantitative flow ratio(QFR)>0.80) and deferred from intervention.Methods:This study is a post-hoc analysis of the FAVOR Ⅲ China trial, which enrolled 3 825 patients with stable or unstable angina pectoris or with myocardial infarction occurring at least 72 hours prior to screening, between December 5, 2018 and January 9, 2020 from 26 research centers in China. Coronary vessels with QFR>0.80 and without interventional treatment were analyzed in this study. The primary endpoint was 3-year target vessel revascularization. Vessels with revascularization (revascularized group) during follow-up were matched 1∶1 using propensity score matching to comparable vessels without revascularization (non-revascularized group). Multivariate Cox regression analysis was used to identify the risk factors for target vessel revascularization (TVR).Results:A total of 6 212 functionally negative vessels with deferred intervention were included in the final analysis, among which 153 vessels (2.5%) underwent TVR during a 3-year follow-up. Prior to propensity score matching, 6 059 vessels comprised the non-revascularized group. At the vessel level, compared to the non-revascularized group, the revascularized group exhibited a significantly higher proportion of males (79.1% (121/153) vs. 70.2% (4 253/6 059), P=0.018), higher body mass index ((25.6±4.0) kg/m2 vs. (24.3±5.2) kg/m2, P=0.003), and a higher prevalence of hypertension (73.9% (113/153) vs. 65.1% (3 944/6 059), P=0.025). And 152 pairs of vessels were successfully matched. Multivariate Cox regression analysis identified in-stent restenosis lesions ( HR=2.59, 95% CI 1.28-5.23, P=0.008) as an independent risk factor for target vessel revascularization. Conclusions:Coronary lesions classified as functionally non-ischemic at baseline are not entirely stable and may progress to lesions that requiring revascularization over time. In-stent restenosis emerges as a critical independent predictor of revascularization.

Objective:Investigate the impact of calcification on the long-term outcomes of patients with coronary chronic total occlusion (CTO) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted. Patients who underwent PCI and had at least one CTO lesion at Fuwai Hospital between January 2010 and December 2013 were consecutively enrolled. Calcification was evaluated by coronary angiography, and patients were divided into two groups: moderate/severe calcification group and non/mild calcification group. Clinical follow-up was completed up to 5 years. Incidence of PCI-related complications and immediate procedural outcomes were compared between two groups, and the primary endpoint was the target lesion failure (TLF) at 5 years after PCI. Clinical follow-up endpoint events were analyzed using Kaplan-Meier survival analysis with log-rank test, and Cox multivariate regression model was used to evaluate the relationship between calcification and TLF.Results:The study included 2 659 CTO patients with an age of (57.2±10.5) years, of whom 442 (16.6%) were female, and among whom 13.5% (360/2 659) had moderate/severe calcification. Compared with the non/mild calcification group, the moderate/severe calcification group had a higher incidence of PCI-related complications (43.2% (156/361) vs. 32.5% (772/2 374), P<0.001) and procedural failure (34.3% (124/361) vs. 24.3% (577/2 374), P<0.001). Additionally, the moderate/severe calcification group showed a higher risk of the primary endpoint event (TLF) during the 5-year follow-up (19.8% vs. 15.3%, log-rank P=0.028). Higher incidence of cardiac death was observed in moderate/severe calcification group (5.7% vs. 2.7%, log-rank P=0.003). Cox multivariate regression analysis revealed that moderate/severe calcified plaques remained an independent risk factor for 5-year TLF after CTO-PCI ( HR=1.34, 95% CI: 1.01-1.79, P=0.043). Conclusion:Compared with CTO patients with non/mild calcification, those with moderate/severe calcification have higher procedural failure and complication rates, as well as poorer long-term prognosis, mainly due to an increase in cardiac death.

Proteins are fundamental carriers as the structural elements and biochemically active entities responsible for catalysis, transport, and regulation. These functions are depending on the protein folding into precise three-dimensional structures, interacting with ligands, and conformational changes. This article reviews the recent progress of nanopores in single-molecule protein sensing, involving the identification of polypeptides and proteins, the conformation changes of protein folding, the molecular structure responsible to the pH of solutions, the molecular interactions, and protein sequencing. These studies provide clues to understand life activities and facilitate the early diagnosis of diseases and design of drugs for precise treatment.

Objective To explore the nephrotoxic effects of exposure to perfluorobutanoic acid (PFBA) and its mechanism in mice, with a particular focus on analyzing the changes in kidney metabolism and their potential implications. Methods The specific pathogen free C57BL/6 mice were randomly divided into control group, low-dose group, and high-dose group, with 10 mice in each group. Mice in the three groups received intragastric administration of PFBA solution at doses of 0, 35 and 350 mg/kg body weight, once per day for seven consecutive days. The histopathological changes of kidneys of mice in these three groups were evaluated. Metabolomic profiling of mouse kidneys was performed using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Differentially accumulated metabolites (DAMs) were identified based on the Human Metabolome Database, and related metabolic pathways were analyzed through MetaboAnalyst 6.0 and Kyoto Encyclopedia of Genes and Genomes (KEGG). Results Histopathological analysis of kidneys showed that the renal pelvis mucosa of mice in the low-dose group presented focal mild inflammatory changes without marked structural damage, whereas mice in the high-dose group showed severe inflammation and partial destruction of renal structure. The kidney coefficient of mice in both low-dose group and the high-dose group decreased (both P<0.05), and the Paller scores of renal tissues increased (both P<0.05) compared with that in the control group. The Paller score of mouse renal tissue in the high-dose group was higher than that in the low-dose group (P<0.05). Metabolomic profiling identified 46 DAMs (26 upregulated, 20 downregulated) in the low-dose group and 104 DAMs (54 upregulated, 50 downregulated) in the high-dose group, with 26 shared DAMs between the two dose groups. KEGG pathway analysis revealed that DAMs were mainly involved in metabolic pathways such as glycerophospholipid metabolism, glycerolipid metabolism, sphingolipid and steroid hormone synthesis. Conclusion Acute exposure to PFBA can cause kidney injury in mice. Lipid metabolism pathways such as glycerophospholipid and sphingolipid metabolism is involved in the development of acute renal toxicity of PFBA.

Objective:To investigate the clinical efficacy and safety of the triplet regimen of flumatinib, venetoclax (VEN) and azacitidine (AZA) for Philadelphia chromosome-positive (Ph +) mixed-phenotype acute leukemia (MPAL). Methods:The clinical data of 2 Ph + MPAL patients treated with triplet regimen of flumatinib, VEN and AZA who were admitted to the Institute of Hematology & Blood Diseases Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College in February and March 2023 were retrospectively analyzed, and the relevant literature was reviewed. Results:Patient 1 was a 56-year-old female, and patient 2 was a 59-year-old male. Both patients were diagnosed with Ph + B cell/myeloid (B/My) MPAL. After the first course of induction chemotherapy with the triplet regimen, patient 1 achieved hematological complete remission (HCR), complete cytogenetic remission (CCyR) and major molecular response (MMR), and patient 2 achieved HCR and CCyR. During the entire treatment process, the adverse reactions of two patients were mainly fever and ≥ grade 3 hematological adverse reactions, which were relieved after the use of antibiotics and intermittent infusion of blood products. When the patient achieved HCR and received consolidation treatment with the same regimen, the adverse reactions were mild. Conclusions:The triplet regimen of flumatinib, VEN and AZA is safe and effective for the treatment of Ph + MPAL, and is a new induction therapy option for such patients.

OBJECTIVE: To observe the efficacy and safety of Tiaowei Jiannao acupuncture (acupuncture for regulating defensive qi and nourishing brain) for post-ischemic stroke insomnia (PISI). METHODS: A total of 96 patients with PISI were randomized into an acupuncture group (32 cases, 1 case was excluded), a medication group (32 cases, 1 case dropped out, 1 case was excluded) and a sham-acupuncture group (32 cases, 1 case dropped out, 1 case was excluded). In the acupuncture group, Tiaowei Jiannao acupuncture was applied at bilateral Shenmai (BL62), Zhaohai (KI6), Hegu (LI4), Taichong (LR3), and Baihui (GV20), Sishencong (EX-HN1), Yintang (GV24⁺), Shenting (GV24), once a day, 1-day interval was taken after 6-day treatment, for 3 weeks totally. In the medication group, eszopiclone tablet was given orally, 1-3 mg a time, once a day for 3 weeks. In the sham-acupuncture group, non-invasive sham acupuncture was applied, the acupoint selection, frequency and course of treatment were the same as the acupuncture group. Before treatment, after 2,3 weeks of treatment, the scores of Pittsburgh sleep quality index (PSQI), self-rating sleep scale (SRSS), National Institutes of Health Stroke scale (NIHSS), Hamilton depression scale-17 (HAMD-17) were observed; before and after treatment, the sleep parameters were recorded using polysomnography (PSG); and the efficacy and safety were evaluated after treatment in the 3 groups. RESULTS: After 2,3 weeks of treatment, the scores of PSQI, HAMD-17 and SRSS in the acupuncture group and the medication group, as well as the SRSS scores in the sham-acupuncture group were decreased compared with those before treatment (P<0.05); after 2 weeks of treatment, the NIHSS score in the acupuncture group was decreased compared with that before treatment (P<0.05); after 3 weeks of treatment, the NIHSS scores in the acupuncture group, the medication group and the sham-acupuncture group were decreased compared with those before treatment (P<0.05). After 3 weeks of treatment, the scores of PSQI, SRSS, HAMD-17 and NIHSS in the acupuncture group and the medication group, as well as the NIHSS score in the sham-acupuncture group were decreased compared with those after 2 weeks of treatment (P<0.05).
