OBJECTIVE To identify the quality markers （Q-Markers） of Hyssopus cuspidatus against airway remodeling in bronchial asthma （referred to as “asthma”）， an d to provide a reference for the quality control research of H. cuspidatus based on pharmacodynamic activity. METHODS Potential active components and action targets of H. cuspidatus were screened by network pharmacology method. Using human airway smooth muscle cells （HASMCs） as objects， airway remodeling cell model was induced by platelet-derived growth factor-BB （PDGF-BB）； validation test was then performed for anti-asthmatic effects of H. cuspidatus and the potential active components. HPLC method was employed to establish the fingerprints of 14 batches of H. cuspidatus samples， and chemometric analysis was also conducted. Combined with the results of pharmacodynamic experiments and fingerprint analysis， the Q-Markers of H. cuspidatus against airway remodeling in asthma were determined. RESULTS&CONCLUSIONS Network pharmacology analysis showed that the potential active components of H. cuspidatus against asthma might be flavonoids and phenolic acids such as luteolin， quercetin and rosmarinic acid， and the core anti-asthmatic targets were interleukin-6， mitogen-activated protein kinase， etc. In vitro experimental results confirmed that 25， 50， 100 μg/mL of H. cuspidatus ， as well as neochlorogenic acid （80 μmol/L）， acacetin （80 μmol/L）， salvianolic acid B （40 μmol/L） and quercetin-3- O - β -D-glucuronide （80 μmol/L）， significantly reduced the cell viability induced by PDGF-BB， inhibited cell proliferation， migration， and the phosphorylation level of extracellular signal-regulated protein kinase 1/2， decreased the levels of interleukin-6， tumor necrosis factor-α and reactive oxygen species， and generally arrested cells in the G 0 /G 1 phase （ P ＜0.05）. Fingerprint analysis showed that there were 27 common peaks in the fingerprints of the 14 batches of H. cuspidatus samples， with 15 compounds （including luteolin） identified， and the similarities of fingerprints were all greater than 0.8. The 14 batches of samples could be divided into three categories： S1-S7 as one category， S8-S13 as one category， and S14 as one category. The variable importance in the projection values of rosmarinic acid， chlorogenic acid， caffeic acid， salvigenin， luteolin， ferulic acid， quercetin-3- O - β -D-glucuronide， and the components corresponding to peaks 5 and 8 were greater than 1， indicating they were potential differential markers affecting quality. Integrating network pharmacology， in vitro experimental validation， and chemometric analysis， rosmarinic acid， neochlorogenic acid， caffeic acid， salvigenin， luteolin， ferulic acid， quercetin-3- O - β -D-glucuronide， acacetin， salvianolic acid B and chlorogenic acid may be the Q-Markers of H. cuspidatus against asthma.

OBJECTIVE To control the quality of Inula salsoloides from different producing areas in Xinjiang. METHODS The macroscopic and microscopic identification of medicinal materials was performed using conventional morphological and microscopic observation methods. Thin-layer chromatography（TLC）was applied for the qualitative identification of chlorogenic acid in the medicinal materials. In ac cordance with the General Principles in Volume Ⅳ of the 2025 edition of the Chinese Pharmacopoeia ， the contents of water， total ash， acid-insoluble ash， and extractives of the samples were determined. High-performance liquid chromatography was used to measure the contents of chlorogenic acid， isoquercitrin， and quercetin. Taking water， total ash， acid-insoluble ash， extractives， and the contents of chlorogenic acid， isoquercitrin， and quercetin as evaluation indices， the entropy weight-TOPSIS method was adopted to comprehensively evaluate the quality of 18 batches of samples. RESULTS I. salsoloides from Xinjiang exhibited distinct macroscopic and microscopic characteristics， and the qualitative TLC identification results for chlorogenic acid were clear and reliable. The water content ranged from 6.20% to 7.23%， the total ash content from 12.27% to 15.80%， the acid-insoluble ash content from 1.89% to 2.57%， and the extractive contents from 21.24% to 28.09%. The contents of chlorogenic acid， isoquercitrin， and quercetin were 0.198 5 to 2.335 0 mg/g， 0.014 5 to 0.402 8 mg/g， and 0.016 5 to 0.578 7 mg/g， respectively. The comprehensive closeness degrees of 18 batches of samples were 0.106 to 0.673. CONCLUSIONS The established quality control method is stable and reliable， which can be applied to the quality control of I.salsoloides ， there are significant differences in the quality of medicinal materials from different producing areas.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

Objective:To investigate the relationship between retinoblastoma binding protein 1 (RB1) gene deletion and the prognosis of multiple myeloma (MM) patients, and the possible effect of renal insufficiency on it.Methods:A retrospective cohort study was conducted. The clinical data and follow-up information of MM patients who were treated in the Second Affiliated Hospital of Xuzhou Medical University and the Affiliated Hospital of Xuzhou Medical University from December 2020 to November 2023 were collected. According to the presence of RB1 gene deletion in bone marrow samples detected by fluorescence in situ hybridization (FISH), the patients were divided into the RB1 gene deletion group and the RB1 gene non-deletion group, and the clinicopathological characteristics and hematological index levels were compared between the two groups. Renal insufficiency was determined by renal function assessment indicator serum creatinine (Scr) >177 μmol/L. The Spearman test was used to analyze the relationship between the number of RB1 gene deletion positive cells and levels of Scr, hemoglobin and serum calcium in MM patients. The Kaplan-Meier method was used to analyze progression-free survival (PFS), and the Cox proportional hazards model was used to determine the influencing factors of PFS in all MM patients and RB1 gene deletion and non-deletion MM patients.Results:A total of 75 MM patients were enrolled, of whom 24 (32.0%) had RB1 gene deletion. There were no significant differences in gender, age ≥65 years old, bone destruction and lactate dehydrogenase level between the RB1 gene deletion and non-deletion groups (all P > 0.05). There were significant differences in the distributions of patients in each stage of MM International Staging System (ISS) and revised International Staging System (R-ISS) between the two groups, as well as in hemoglobin, serum calcium, Scr, β 2-microglobulin, serum albumin levels, and the proportion of bone marrow plasma cells (all P < 0.05). The number of RB1 gene deletion positive cells was positively correlated with Scr level ( r = 0.863, P = 0.016), but not with hemoglobin and serum calcium levels (both P > 0.05). The PFS of the RB1 gene non-deletion group was better than that of the RB1 gene deletion group (1-year PFS rate: 83.5% vs. 71.7%, 2-year PFS rate: 56.3% vs. 26.3%), and the difference was statistically significant ( P = 0.012). PFS in the non-renal insufficiency group was better than that in the renal insufficiency group (1-year PFS rate: 85.6% vs. 61.9%, 2-year PFS rate: 58.0% vs. 13.5%), and the difference was statistically significant ( P = 0.001). The PFS of patients without renal insufficiency in both the RB1 gene deletion and non-deletion groups was better than that in patients with renal insufficiency, and the differences were statistically significant (both P < 0.05). Multivariate Cox regression analysis showed that ISS stage Ⅲ was an independent risk factor for poor PFS in MM patients (stage Ⅲ vs. stage Ⅰ, HR = 11.317, 95% CI: 1.220-104.979, P = 0.033). Multivariate Cox regression analysis in RB1 gene deletion and non-deletion groups showed that ISS stage Ⅲ (stage Ⅲ vs. stageⅠ, HR = 4.166, 95% CI: 1.419-12.225, P = 0.009), R-ISS stage Ⅲ (stage Ⅲ vs. stage Ⅰ, HR = 3.800, 95% CI: 1.005-14.367, P = 0.049), serum calcium > 2.52 mmol/L (> 2.52 mmol/L vs. ≤2.52 mmol/L, HR = 2.398, 95% CI: 1.037-5.546, P = 0.041) and renal insufficiency (yes vs. no, HR = 2.363, 95% CI: 1.021-5.472, P = 0.045) were independent risk factors for poor PFS in RB1 gene non-deletion MM patients, and serum calcium >2.52 mmol/L (>2.52 mmol/L vs. ≤ 2.52 mmol/L, HR = 3.673, 95% CI: 1.160-11.627, P = 0.027) and renal insufficiency (yes vs. no, HR = 3.985, 95% CI: 1.220-13.016, P = 0.022) were independent risk factors for poor PFS in RB1 gene deletion MM patients. Conclusions:The PFS of MM patients with RB1 gene deletion is worse than that of patients without RB1 gene deletion, RB1 gene deletion may be related to renal insufficiency in MM patients, and the prognosis of MM patients with RB1 gene deletion and renal insufficiency may be worse.

Objective:To construct a training program for epilepsy specialist nurses, so as to provide a theoretical basis for the training and development of epilepsy specialist nurses.Methods:A preliminary training program for epilepsy specialist nurses was developed based on literature review, semi-structured interview, focus group discussion and clinical practice experience. Delphi method was used to select 20 experts from several regions of China for two rounds of consultation.Results:In the two rounds of expert consultation, the effective recovery rate of the questionnaire was both 100%, the expert authority coefficient was 0.908 and 0.958, and the degree of coordination of expert opinions was 0.180 to 0.229 and 0.138 to 0.189, respectively ( P<0.05). The standardized training program for epilepsy specialist nurses was finally constructed, including 5 first-level indicators (admission conditions, general theory courses, specialty theory courses, specialty nursing practice courses, training modes and effectiveness evaluation), 15 second-level indicators and 61 third-level indicators. Conclusions:The training program constructed for epilepsy specialist nurses is scientific and reasonable, with certain reliability and practicality, which provides a theoretical basis for the training of epilepsy specialist nurses, and promotes the common development of China's epilepsy specialist nurse team.

Objective:To investigate the status of leisure crafting and post competence and their correlation among anesthesia specialist nurses.Methods:A convenience sampling method was used to conducted a questionnaire survey on 280 anesthesia specialist nurses at grade A tertiary hospitals in 19 provinces of China. Data were collected using a general information questionnaire, the Chinese version of Leisure Crafting Scale, and the Post Competency Scale for Anesthesia Specialist Nurses. SPSS 24.0 was used for t test and one-way analysis of variance. A Pearson correlation analysis was used to assess relationships between variables. Results:The total score of leisure crafting was (30.41±6.69) and the average score was (3.38±0.74). The total score of post competency was (141.76±21.76) and the average score was (3.73±0.57). A positive correlation was observed between leisure crafting and post competency ( r=0.215, P<0.01). Conclusions:Managers should encourage anesthesia specialist nurses to actively engage in leisure crafting and provide diverse opportunities for leisure crafting to improve their post competence and ultimately the quality of anesthesia nursing.

Objective:To investigate the predictive value of the cancer antigen 125 (CA 125) elimination rate constant K (KELIM) score for no visible residual disease (R0) and prognosis in high-grade serous ovarian carcinoma (HGSOC) patients undergoing neoadjuvant chemotherapy (NACT)+interval debulking surgery (IDS). Methods:A retrospective analysis was conducted on 78 HGSOC patients treated with NACT+IDS at Beijing Hospital, from June 2014 to June 2024. The KELIM score was calculated, and its predictive value for R0 resection, chemotherapy response score (CRS), platinum-free interval (PFI), progression-free survival (PFS) time, and overall survival (OS) time was analyzed.Results:(1) The mean age at diagnosis was (61.9±9.9) years. The mean KELIM score was 1.1±0.4, with 44 patients having KELIM score≥1 and 34 having KELIM score <1. (2) Patients with KELIM score ≥1 had significantly higher rates of R0 resection (84% vs 56%; P=0.006), CRS3 grading (41% vs 0; P<0.001), and PFI ≥6 months (84% vs 53%; P=0.04) compared to those with KELIM score <1. Additionally, the median PFS time (18.7 vs 13.2 months; P<0.001) and OS time (34.8 vs 29.9 months; P=0.007) were significantly longer in the KELIM score ≥1 group. Chemosensitivity: patients with PFI <6 months had a significantly lower median KELIM score than those with PFI ≥6 months (0.8 vs 1.2; P=0.005). Surgical outcome: patients achieving R0 resection had a significantly higher median KELIM score than those without R0 (1.2 vs 0.7; P<0.001). (3) Univariate analysis identified non-R0 resection, CRS3 grading, lack of poly adenosine diphosphate ribose polymerase (PARP) inhibitor maintenance therapy, and KELIM score <1 as significant risk factors for OS time (all P<0.05). Multivariate analysis confirmed non-R0 resection ( HR=3.78,95% CI: 1.13-12.66; P=0.031), no PARP inhibitor maintenance ( HR=7.41,95% CI:1.82-30.15; P=0.005), and KELIM score <1 ( HR=5.14,95% CI:1.41-18.72; P=0.013) as independent risk factors for OS time. Conclusions:The KELIM score may serve as a predictive marker for chemosensitivity, R0 resection, PFS time, and OS time in HGSOC patients undergoing NACT+IDS. KELIM score<1 is an independent risk factor for OS.

Objective To establish a method for simultaneous determination of trace levels of microcystins,cylindrospermopsin,anatoxin,and nodularin in lake water based on liquid chromatography-tandem mass spectrometry(LC-MS/MS).Methods After being adjusted to alkaline conditions and mixed with six internal standards,the water samples were enriched using dual HLB and ENVI-Carb cartridges.The eluates were then evaporated under nitrogen,reconstituted,and subjected to instrumental analysis.Both water and acetonitrile containing 0.1%formic acid were used as mobile phases.An ACQUITY UPLC? BEH C18 column(150 mm×2.1 mm,1.7 μm)was selected to separate the target cyanotoxins.Multiple reaction monitoring was applied for data acquisition,and quantification was accomplished using internal standard methods.Results Within certain concentration ranges,all 14 cyanotoxins examined in the study showed good linearity,with all correlation coefficients greater than 0.998.When the water volume was 100 mL,the limits of detection and quantification for the 14 cyanotoxins were 0.1-0.9 ng/L and 0.3-2.9 ng/L,respectively,and spiked recoveries and relative standard deviations were 81.7%-132.9%and 1.2%-14.9%,respectively.In the 10 lake water samples analyzed,cylindrospermopsin,anatoxin-α,and multiple microcystins were detected.Conclusion The method developed in the study has high-throughput capacity,as well as high sensitivity,accuracy,and reliability.The method can be applied in the simultaneous detection of microcystins,cylindrospermopsin,anatoxin,and nodularin in lake water.

Objective: To analyze the iodine nutritional status of children aged 8-10 in Baoshan City, so as to comprehensively evaluate the effectiveness of eliminating and consolidating iodine deficiency disorders in Baoshan City. Methods: From 2018 to 2024, a stratified random sampling method was used to sample 7 363 non boarding children aged 8-10 from 35 survey sites in 5 counties of Baoshan City (Longyang County, Shidian County, Changning County, Tengchong City, Longling County). The salt iodine content and urinary iodine concentration were detected, and the thyroid volume of children was measured by ultrasound. Group comparison was conducted by using Mann-Whitney U test, Kruskal-Wallis H test, and Chi square test. Spearman rank correlation analysis was used to investigate the correlation of salt iodine, urinary iodine and thyroid volume. Results: A total of 7 361 samples of household edible salt for children were detected. The iodized salt coverage rate was 99.70%, the qualified iodized salt consumption rate was 97.02 %. The proportion of unqualified iodized salt fluctuated and decreased from 3.14% in 2018 to 2.14% in 2024. The median iodine content of household edible salt for children was 23.70 (21.60, 25.80) mg/kg. The median urinary iodine of children was 217.41 (152.40, 294.59) μg/L, and the proportions of iodine deficiency, adequate iodine, and iodine excess were 9.75 %, 66.66%, and 23.58%, respectively. There were statistically significant differences in the median urinary iodine of children among different years, ages, genders and before and after the supply of non iodized salt ( Z/H =134.88, 11.04,-4.28,-2.66, all P < 0.01). An average thyroid volume of children was 3.32 (2.77, 3.93) mL, with a goiter rate of 1.91%. Before and after the implementation of non iodized salt supply in Baoshan City in 2023, there were no statistically significant differences in the median iodine content of household edible salt and the goiter rate of children ( Z/χ 2=-1.54, 3.25, both P >0.05), but there were statistically significant differences in the qualified status of iodized salt, the median urinary iodine, and the frequency distribution of urinary iodine ( χ 2/Z =15.53,-2.66, 10.14, all P <0.05). Salt iodine was positively correlated with urinary iodine ( r =0.04) and negatively correlated with thyroid volume ( r =-0.07), and urinary iodine was negatively correlated with thyroid volume ( r =-0.03) (all P < 0.05 ). The thyroid volume of children consuming iodized salt was larger than that of children consuming non iodized salt ( H = 9.99 ), and there were statistically significant differences in thyroid volume among children with different urinary iodine levels ( H =15.13) (both P <0.01). Conclusions From 2018 to 2024, the overall iodine nutritional level of children aged 8-10 in Baoshan City is at an adequate level. The elimination status of iodine deficiency disorders has been continuously consolidated.
