Cervical spine health issues not only seriously affect patients' quality of life but also impose a heavy burden on the social healthcare system. Existing guidelines lack sufficient clinical guidance on lifestyle and work habits, such as exercise, posture, daily routine, and diet, making it difficult to meet practical needs. To address this, relying on the China Association of Chinese Medicine, Wangjing Hospital of China Academy of Chinese Medical Sciences took the lead and joined hands with more than ten institutions to form a multidisciplinary guideline development group. For the first time, the group developed the Guidelines for Cervical Spine Health Intervention based on evidence-based medicine methods, strictly following the standardized procedures outlined in the World Health Organization Handbook for Guideline Development and the Guiding Principles for the Formulation/Revision of Clinical Practice Guidelines in China (2022 Edition). This proposal systematically explains the methods and steps for developing the guideline, aiming to make the guideline development process scientific, standardized, and transparent.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Notum, a negative feedback regulator of the Wnt signaling, has emerged as a promising target for treating glucocorticoid-induced osteoporosis (GIOP). This study showcases an efficient strategy for discovering the anti-Notum constituents from herbal medicines (HMs) as novel anti-GIOP agents. Firstly, a rapid-responding near-infrared fluorogenic substrate for Notum was rationally engineered for high-throughput identifying the anti-Notum HMs. The results showed that Bu-Gu-Zhi (BGZ), a known anti-osteoporosis herb, potently inhibited Notum in a competitive-inhibition manner. To uncover the key anti-Notum constituents in BGZ, an efficient strategy was adapted via integrating biochemical, phytochemical, computational, and pharmacological assays. Among all identified BGZ constituents, three furanocoumarins were validated as strong Notum inhibitors, while 5-methoxypsoralen (5-MP) showed the most potent anti-Notum activity and favorable safety profiles. Mechanistically, 5-MP acted as a competitive inhibitor of Notum via creating strong hydrophobic interactions with Trp128 and Phe268 in the catalytic cavity of Notum. Cellular assays showed that 5-MP remarkably promoted osteoblast differentiation and activated Wnt signaling in dexamethasone (DXMS)-challenged MC3T3-E1 osteoblasts. In dexamethasone-induced osteoporotic mice, 5-MP strongly elevated bone mineral density (BMD) and improved cancellous and cortical bone thickness. Collectively, this study constructs a high-efficient platform for discovering key anti-Notum constituents from HMs, while 5-MP emerges as a promising anti-GIOP agent.

Objective To analyze the characteristics of methadone-related poisoning cases and provide a reference for forensic identification.Methods A total of 71 cases of methadone-related poisoning re-ported from 1998 to 2023 in China and 26 cases of methadone-related deaths reported from 2013 to 2018 in Italy were retrieved from databases including PubMed,Wanfang and CNKI.The general infor-mation,forensic pathological and toxicological characteristics were analyzed.Results Among the 71 methadone-related poisoning cases in China,there were 54 cases(76.06%)of poisoning without death and 17 cases(23.94%)of death from poisoning.There were 54 male cases(76.06%),and 51 cases(71.83%)aged 19 to 39 years old.There were 35 cases(49.30%)of poisoning caused by methadone alone,and 32 cases(45.07%)were poisoning caused by methadone combined with other substances or drugs including heroin and benzodiazepines.Most of the poisoned showed coma,respiratory depres-sion and miosis.Signs of asphyxia were often found by autopsy.The mass concentration of methadone detected in the blood of 6 deceased ranged from 0.112 to 3.000 mg/L.Among the 26 methadone-related deaths in Italy,22 cases were male(84.62%).There were 6 cases(23.08%)caused by methadone alone,and 20 cases(76.92%)died from methadone combined with other substances or drugs.The mass concentration of methadone in blood ranged from 0.181 to 4.059 mg/L.Conclusion The propor-tions of poisoning cases caused by methadone alone and methadone combined with other substances or drugs are comparable in China.The majority of deceased caused by methadone poisoning shows typi-cal triad of coma,respiratory depression and miosis,which helps forensic experts determine the cause of death related to methadone.Additionally,it is necessary to increase the routine testing of the con-centration of methadone and its combined substances or drugs in deceased,and collect data for the in-terpretation of the results of related cases.

Objective To investigate the effect and mechanism of circular RNA_0009910(circ_0009910)on the proliferation and apoptosis of non-small cell lung cancer cells.Methods A549 cells were randomly divided into groups and transfected as follows:si-NC group,si-circ_0009910 group,miR-NC group,miR-34a-5p group,si-circ_0009910+anti-miR-NC group,and si-circ_0009910+anti-miR-34a-5p group.After successful transfec-tion,cell proliferation was measured using the CCK-8 assay.Dual-luciferase reporter assays were used to vali-date the target gene of circ_0009910.Apoptosis of A549 cells was analyzed by flow cytometry.Protein expres-sion levels of B-cell lymphoma-2(Bcl-2),transmembrane receptor protein 1(Notch1),cell proliferation-asso-ciated nuclear antigen(Ki-67),Bcl-2-associated X protein(Bax),and cysteine aspartic acid protease-3(Caspase-3)were detected by Western blot.Cells from each group were subcutaneously injected into the abdo-mens of male nude mice to establish xenograft models.Tumor volume,tumor weight,and protein expression in tumor tissues were measured.Results Compared with the si-NC group,the si-circ_0009910 group showed significantly reduced A549 cell proliferation,increased apoptosis,decreased expression of Ki-67,Notch1,and Bcl-2,and increased expression of Bax and Caspase-3(P＜0.05).Compared with the miR-NC group,the miR-34a-5p group exhibited significantly reduced luciferase activity after transfection with wild-type circ_0009910(P＜0.05).The si-circ_0009910 group showed upregulated miR-34a-5p expression compared to the si-NC group.The miR-34a-5p group demonstrated weaker proliferation,higher apoptosis,downregulated Bcl-2,Notch1,and Ki-67,and upregulated Bax and Caspase-3 compared to the miR-NC group(P＜0.05).Compared with the si-circ_0009910+anti-miR-NC group,the si-circ_0009910+anti-miR-34a-5p group exhibited en-hanced proliferation,reduced apoptosis,upregulated Bcl-2,Notch1,and Ki-67,and downregulated Bax and Caspase-3(P＜0.05).In vivo,the si-circ_0009910 and miR-34a-5p groups showed smaller tumor volumes and weights,downregulated Notch1,Ki-67,and Bcl-2,and upregulated Bax and Caspase-3 in tumor tissues com-pared to their respective control groups(P＜0.05).Conclusion Low expression of circ_0009910 inhibits A549 cell proliferation and promotes apoptosis,potentially via the miR-34a-5p/Notch1 signaling pathway.

Objective:To investigate the interactive effects of loss of the only child and childhood trauma on brain structure, function, and structure-function coupling, and to analyze their association with clinical symptom.Methods:A total of 112 parents who lost their only child and participated in the psychological aid project organized by Local Civil Affairs Department in Sunan aear of Jiangsu Province in China from April 2021 to July 2021 and 36 healthy controls recruited from the community during the same period were selected. Based on childhood trauma questionnaire scores, parents who had lost their only child were divided into those with childhood trauma (group A, n=55) and those without childhood trauma (group B, n=57); similarly, the healthy controls were divided into a group with childhood trauma (group C, n=12) and a group without childhood trauma (group D, n=24). All participants were evaluated by clinical scales such as Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), and Mini-Mental State Examination (MMSE). MRI 3D-T1 structural images and resting-state functional magnetic resonance imaging data were collected; gray matter volume (GMV) and degree centrality (DC) were calculated by standardized image preprocessing procedure, and ratio of DC to GMV within each voxel was computed to obtain the structure-function coupling map. A two-factor analysis of variance was used to analyze the independent effect and interactive effect of loss of the only child and childhood trauma on GMV, DC, and DC/GMV coupling value. Spearman rank correlation analysis was used to evaluate the associations of above indicators in brain regions with significant difference in independent effect and interactive effect with clinical scale scores. Results:(1) Compared with the participants without childhood trauma (group B+group D), the participants with childhood trauma (group A+group C) showed significantly reduced GMV in the left middle temporal gyrus and right dorsolateral superior frontal gyrus (voxel-level P<0.01, cluster-level P<0.05, Gaussian random field [GRF] corrected). A significant interactive effect of loss of the only child and childhood trauma on GMV in the right precuneus was observed (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). (2) Compared with the healthy controls, parents who had lost their only child exhibited significantly increased DC in the left middle frontal gyrus (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). Compared with participants without childhood trauma, participants with childhood trauma showed significantly increased DC in the right thalamus (voxel-level P<0.01, cluster-level P< 0.05, GRF corrected). A significant interactive effect of loss of the only child and childhood trauma on DC in the left dorsolateral superior frontal gyrus was observed (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). (3) Compared with the healthy controls, parents who had lost their only child showed significantly decreased DC/GMV coupling value in the left middle frontal gyrus (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). Compared with participants without childhood trauma, participants with childhood trauma showed significantly increased DC/GMV coupling value in the right thalamus (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). A significant interactive effect of loss of the only child and childhood trauma on DC/GMV coupling value in the left dorsolateral superior frontal gyrus was observed (voxel-level P<0.01, cluster-level P<0.05, GRF corrected). (4) Correlation analysis revealed that GMV in the right precuneus with significant interactive effect of loss of the only child and childhood trauma was positively correlated with MMSE score ( r s=0.317, P=0.010, Bonferroni corrected). GMV in the left middle temporal gyrus with significant independent effect of childhood trauma was positively correlated with both HAMD score and HAMA score ( r s=0.362, P=0.006; r s= 0.349, P=0.008, Bonferroni corrected). Conclusion:Loss of the only child and childhood trauma can interact to jointly affect the brain structure, function, and structure-function coupling; and some of these brain structure alterations are closely associated with clinical symptoms.

Objective:To summarize the experience of repairing partial areolar necrosis following reduction mammaplasty.Methods:A retrospective analysis was conducted on clinical data from patients who experienced partial areola necrosis after reduction mammaplasty. These patients were treated or consulted at the Department of Plastic Surgery, Zhongshan Hospital, Fudan University, between January 2017 and February 2023. Preoperatively, daily dressing changes were performed on the necrotic areola wounds until the boundaries of necrosis were clearly defined. Debridement and repair were then carried out by resecting bilateral breast glandular tissue through the original incision to reduce breast volume, followed by narrowing the areola radius. If no areola defect remained after narrowing, direct suturing was performed; if defects persisted, the resected normal areola skin was used for grafting. Postoperative follow-up was conducted to observe areola recovery and complications. At the 6-month postoperative mark, patient satisfaction was evaluated using a 5-level scale (very satisfied, satisfied, neutral, dissatisfied, very dissatisfied). An experienced plastic physician, not involved in the surgery, assessed areolar outcomes based on four criteria: color, softness, shape, and scarring, with each criterion scored from 1 to 4 (higher scores indicating better outcomes).Results:Eight female patients (9 necrotic areolas) were included in the study, with a mean age of (31.8±5.4) years and a mean body mass index of (24.1±1.8) kg/m 2. Among the 9 necrotic areolas, 3 had defect areas greater than 50% of the total areola area, while 6 had defects less than 50%. Direct suturing after areola narrowing was performed in 3 areolas, while free areola skin grafting was used in 6 areolas. Postoperatively, 2 cases exhibited mild epidermal erosion at the graft site, which improved with dressing changes. No complications such as infection, bleeding, hematoma, or seroma occurred. At the 6-month follow-up, all 8 patients demonstrated good wound healing, and all 9 areolas survived. The areolas exhibited consistent shape and color bilaterally, without significant pigmentation changes, depigmentation, or irregular shapes. In the 6 grafted areolas, the grafted skin color closely matched the surrounding native areola tissue, with no obvious demarcation or scar hyperplasia. Patient satisfaction was rated as very satisfied in 3 cases and satisfied in 5 cases. According to the physician’s evaluation, the scores for color, softness, shape, and scarring were (3.7±0.5), (3.8±0.4), (3.3±0.7) and (3.2±0.7) points, respectively. Conclusion:Partial areola necrosis following reduction mammaplasty can be effectively repaired by further reducing breast volume and narrowing the areola for direct suturing or by grafting excess areola skin to the defect site. A satisfactory appearance can be achieved after surgery.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.
