Objective To investigate the current status of postoperative analgesia practices among patients undergoing neurosurgical procedures in China to provide evidence-based support for formulating a standardized postoperative analgesia consensus and optimizing pain management strategies in the field of neurosurgery.Methods A questionnaire was designed with Wenjuanxing,covering 42 items in aspects including general information of participating medical institutions,current practices of neurosurgical postoperative analgesia,anesthesiologists'understanding and implementation of analgesic concepts,and the status of postoperative analgesic management.Distributed through the Chinese Association of Anesthesiologists,the questionnaire data were exported for descriptive statistical analysis after collection.Results A total of 116 medical institutions participated in this survey,with 178 valid questionnaires collected.Over 90%of respondents recognized the clinical necessity of postoperative analgesia for neurosurgical patients,while the actual implementation rate was only 53.9%.Although most hospitals adopted techniques such as local infiltration anesthesia,scalp nerve blocks,patient-controlled intravenous analgesia,and multimodal analgesia,their actual utilization rates remained low.Less than 50%of participating centers implemented preventive analgesia.Despite high awareness of chronic postoperative pain(96.9%),follow-up rates were relatively low.More than half of the institutions lacked acute pain service for neurosurgical analgesia management.Conclusion Postoperative analgesia in clinical neurosurgical practice in China currently remains suboptimal,with inadequate management.There is an urgent need to enhance public education,facilitate multidisciplinary collaboration,and formulate standardized guidelines for clinical practice.

Objective:To explore the feasibility and clinical outcomes of transperineal prostate multimodal image fusion-targeted biopsy under the day surgery model.Methods:Clinical data of 258 patients who underwent transperineal prostate biopsy at the Second Affiliated Hospital of Xi’an Jiaotong University between December 2022 and June 2024 were retrospectively analyzed. Patients were divided into two groups，and the experimental group（ n = 141）underwent transperineal prostate multi-modal image-fusion targeted biopsy in the day-surgery mode，with age of（70.0 ± 8.8）years，median prostate-specific antigen（PSA）level of 11.10（7.63?17.06）ng/ml，and median Prostate Imaging Reporting and Data System（PI-RADS）score of 4（3，5）. The control group（ n = 117）underwent traditional transperineal systematic biopsy，with age of（69.3 ± 7.4）years，median PSA of 25.20（16.18-54.40）ng/ml，and median PI-RADS score of 4（3，5）. The experimental group was given the day surgery mode：preoperatively，multiparametric magnetic resonance imaging（mpMRI）of the prostate was multimodally fused with ultrasound images，the location of target lesions in the prostate was manually mapped，and a targeted biopsy plan was developed. Intraoperatively，under ultrasound guidance，precise puncture was performed at the lesion sites，followed by systematic biopsy. After the operation，the patients were observed for 4-6 hours，and could be discharged if there were no obvious abnormalities，with the total hospitalization time within 24 hours. For the control group，the conventional biopsy mode was used. Intraoperatively，under ultrasound guidance，the standard 12-core transperineal systematic biopsy protocol was adopted，and sampling was conducted according to the anatomical regions of the prostate（base，midportion，apex，transition zone，and peripheral zone）to cover the entire gland. Patients in this group required routine hospitalization，with a hospital stay of 3-5 days. Operative time，intraoperative pain Numerical Rating Scale（NRS）score，complications within one week postoperatively，treatment costs，overall prostate cancer detection rate，and clinically significant prostate cancer（csPCa，defined as Gleason score ≥ 7 or pathological stage ≥ T 2b）detection rate were compared between the two groups. Results:All procedures were successfully completed without special incidents. The operative time was（13.49 ± 2.00）min in the experimental group and（13.05 ± 2.89）min in the control group，showing no significant difference（ P > 0.05）. The intraoperative pain NRS scores were（3.01 ± 1.17）and（3.10 ± 1.25）in the experimental and control groups，respectively，with no significant difference（ P > 0.05）. Pathological examination revealed that the overall prostate cancer detection rates were 46.8%（66/141）in the experimental group and 42.7%（50/117）in the control group，while the csPCa detection rates were 35.5%（50/141）and 31.6%（37/117），respectively. The differences were not statistically significant（ P > 0.05）. The complication rate was 6.4%（9/141）in the experimental group（including 2 cases of acute urinary retention，3 hematuria，3 fever，and 1 sepsis）and 6.0%（7/117）in the control group（including 3 acute urinary retention，1 hematuria，2 fever，and 1 sepsis），with no significant difference（ P > 0.05）. All complications improved after symptomatic treatment. The treatment costs were（4 063.25 ± 67.26）yuan in the experimental group and（5 185.14 ± 469.15）yuan in the control group，demonstrating a statistically significant difference（ P < 0.05）. Conclusions:Transperineal prostate multimodal image fusion-targeted biopsy can be safely performed under the day surgery model，offering advantages including a relatively high detection rate for csPCa，low complication rate，and better cost-effectiveness.

Following the release of the Technical Requirements on Quality Control and Standard Establishment of Traditional Chinese Medicine Formula Granules by the National Medical Products Administration in 2021, Chinese Pharmacopoeia Commission has promulgated 296 national drug standards so far, and most provinces have started the work of establishing provincial standards as supplements. The promulgation of standards fostered high-quality development of the industry. Since the implementation of national and provincial standards for more than three years, enterprises have gained deep understanding and hands-on experiences on the characteristics, technical requirements, production process, and quality control of traditional Chinese medicine(TCM) formula granules. Meanwhile, challenges have emerged restricting the high-quality development of this industry, including how to formulate quality control strategies for medicinal materials and decoction pieces, how to reduce manufacturing costs, and how to improve the pass rate and product stability under high standards. Based on the work experiences from standard management and process research, this article analyzed the distribution of sources, processing methods, dry extract rate ranges, process requirements for volatile oil-containing decoction pieces, control measures of safety indices, characteristics and trends of setting characteristic chromatograms or fingerprints, characteristics and trends of setting content ranges, and main differences between national standards and provincial standards. On the one hand, this article aims to present main characteristics for deeply understanding different indicators in standards and provide basic ideas for establishing quality and process control systems. On the other hand, from the perspective of industrial practice, suggestions are put forward on the important aspects that need to be focused on in the quality and process control of TCM formula granules.

ObjectiveTo evaluate the quality of Lygodium japonicum (Thunb.) Sw. (L. japonicum, Hai Jin Sha) by comparing its components without stewed (W) and stewed (S) using ultra-high-performance liquid chromatography (UHPLC) and chemometric analysis. Additionally, network pharmacology was employed to investigate the possible mechanisms of action of L. japonicum in the urinary calculi (UC) treatment.MethodsA fingerprinting method was established to identify components through UHPLC-tandem mass spectrometry. Chemometric techniques were used to compare the L. japonicum extraction methods. Furthermore, various network pharmacological approaches were used to identify and analyze the potential targets of the identified components in relation to UC.ResultsThe W and S extracts were distributed into two distinct clusters. Significant differences in the levels of protocatechuic aldehyde, caffeic acid, and p-coumaric acid were observed between S and W. Network pharmacology analysis revealed that the primary targets of L. japonicum in the UC treatment were serum albumin and epidermal growth factor receptors, with potential active components including protocatechuic acid and caffeic acid.ConclusionThis study comprehensively examined the therapeutic components of L. japonicum before and after boiling, shedding light on its potential mechanisms of action in UC treatment. These findings offer valuable insights into the development and utilization of L. japonicum resources.

Objective To investigate the binding interaction between the calmodulin(CaM)mutant D130V and the IQ motif of the car-diac Cav1.2 channel.Methods The binding of mutant CaM-D130V to the IQ motif was predicted by fold recognition modeling,homology modeling,and protein docking.The plasmid was transformed into Escherichia coli BL-21 sensory cells via heat shock at 42 ℃ to induce the expression of glutathione S-transferase(GST)fusion protein.The protein was extracted by ultrasonic fragmentation and purified using GS-4B beads.PreScission protease was applied to remove the GST.SDS-PAGE was performed to detect the purity of protein.A GST pull-down assay was conducted to detect the interaction between CaM-D130V and IQ motif.Results Protein docking results showed that both CaM-WT and CaM-D130V could bind to the IQ motif of the cardiac Cav1.2 channel,but the binding sites of the mutant CaM-D130V to the IQ motif were reduced,and its binding conformation was changed compared with the CaM-WT,with decreased binding energy(|S|reduced from 48.086 6 kcal/mol to 47.309 5 kcal/mol).The GST pull-down assay indicated that the binding of CaM-D130V to IQ motif significantly decreased(P＜0.01),and the affinity was significantly reduced at 2 mmol/L Ca2+concentration compared with CaM-WT.Conclusion The reduced binding ability of CaM-D130V to the IQ motif of the cardiac Cav1.2 channel may contribute to functional alterations in the channel.These findings provide a theoretical basis for understanding the pathogenesis of CaM mutant-associated cardio-vascular diseases as well as targeted therapies.

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

Laccases (LACs), belonging to the multicopper oxidase family, are closely associated with various biological functions including lignin synthesis and responses to biotic and abiotic stresses in plants. However, few studies have reported the laccase genes in China rose (Rosa chinensis). Prickles cause difficulties to the management and harvest of R. chinensis and have become a trait concerned in the breeding. To investigate the expression patterns of laccase genes in roses, we cloned a laccase gene from an ancient variety R. chinensis 'Old Blush' and named it RcLAC15. The expression level of RcLAC15 in prickles was significantly higher than those in roots, stems, and leaves. Fifty-eight laccase genes were identified in the genome of R. chinensis, and bioinformatics analysis revealed that RcLAC15 was a homolog of AtLAC15, predicting that RcLAC15 was a stable hydrophilic protein without transmembrane structures. The recombinant expression vector pBI121-proRcLAC15:: GUS was introduced into Arabidopsis, and GUS staining results showed that the RcLAC15 promoter specifically drove GUS gene expression at the edges of Arabidopsis leaves. In summary, RcLAC15 is a gene specifically expressed in the prickles of R. chinensis. This discovery provides a reference for exploring the biological functions of laccase genes in the prickles of R. chinensis.

Flowering and bolting are important agronomic traits in cruciferous crops such as Brassica juncea. Timely flowering can ensure the crop organ yield and quality, as well as seed propagation. The WRKY family plays an important role in regulating plant bolting and flowering, while the function and mechanism of WRKY12 in B. juncea remain unknown. To explore its function and mechanism in bolting and flowering of B. juncea, we cloned and characterized the BjuWRKY12 gene in B. juncea and found that its expression levels were significantly higher in flowers and inflorescences than in leaves. BjuWRKY12 belonged to the Ⅱc subfamily of the WRKY family, and subcellular localization indicated that the protein was located in the nucleus. Ectopic overexpression of BjuWRKY12 in transgenic lines promoted bolting and flowering, leading to significant increases in the expression levels of flowering integrators SOC1 and FUL. Furthermore, yeast one-hybrid and dual luciferase reporter system assays confirmed that BjuWRKY12 directly bound to the promoters of BjuSOC1 and BjuFUL, undergoing protein-DNA interactions. This discovery gives new insights into the regulation network and molecular mechanisms of BjuWRKY12, laying a theoretical foundation for the breeding of high-yield and high-quality varieties of B. juncea.
