Specification for Quality Control in Traditional Chinese Medicine Clinical Trials（GB/T 47336-2026） is the first national standard in the field of clinical research on traditional Chinese medicine （TCM）， aims to address the core issue that the quality shortcomings of current TCM clinical research restrict the transformation of achievements and international recognition. Through the interpretation of the core contents of this standard， including its scope of application， graded quality control system， TCM-specific quality control requirements， implementation and responsible entities， responsibilities of quality control personnel， formulation of quality control plans， critical nodes of quality control， and quality control archive management， it is believed that the promotion and implementation of this standard are of great significance for improving the standard system of TCM clinical research， enhancing research quality， optimizing the quality management model， and promoting the internationalization process of TCM. Meanwhile， the implementation paths for the standard are discussed， including carrying out pilot applications in institutions， establishing publicity， implementation， and training mechanisms， encouraging multi-party collaborative supervision， and setting up implementation feedback mechanisms. On this basis， the challenges that may be encountered during implementation， such as resource input pressure， difficulties in implementing TCM-specific quality control， and a relative shortage of interdisciplinary composite talents， are sorted out， and corresponding strategies are proposed， which can provide references for relevant researchers and practitioners.

Objective To discuss the regulatory mechanism of nucleotide-binding oligomerzation domain 2(NOD2)/receptor interacting protein 2(RIP2)signaling pathway on inflammatory activation of macrophages in intestinal mucosa and provide experimental evidence for intestinal mucosal inflammation caused by bacterial products.Methods Using the THP-1 monocyte cell line,macrophages were stimulated with muramyl dipeptide(MDP)at varying concentrations and durations.mRNA and protein expression levels of NOD2 and RIP2 were detected.The secretion levels of tumor necrosis factor(TNF)-α and interleukin(IL)-1β in the cell culture supernatant were measured.The most effective siRNA targeting RIP2 and optimal transfection concentration were screened,and the impact of RIP2 gene silencing on MDP-induced inflammatory activation of macrophages was observed.Results After silencing the RIP2 gene,MDP induced a significant decrease in TNF-α and IL-1βsecretion in macrophages,but the changes in cell phenotype were not significantly affected.Conclusion This study revealed the important role of NOD2/RIP2 signaling pathway in inflammatory activation of macrophages,and it is possible to effectively inhibit inflammatory activation of macrophages by interfering with this signaling pathway.

BACKGROUND:Existing studies have compared patients with degenerative lumbar spondylolisthesis with healthy populations,but comparative studies focusing on differences in this aspect of the parameter between these different lumbar spondylolisthesis are lacking.OBJECTIVE:To explore the differences in paraspinal muscle degeneration between isthmic spondylolisthesis and degenerative lumbar spondylolisthesis,and their correlation with low back pain symptoms.METHODS:A total of 107 patients with lumbar spondylolisthesis treated in Affiliated Hospital of Xuzhou Medical University between February 2019 and August 2023 were analyzed retrospectively.They were divided into the isthmic spondylolisthesis group(39 patients)and the degenerative lumbar spondylolisthesis group(68 patients)according to the type of spondylolisthesis.Paravertebral muscle tissue parameters were compared and analyzed as well as functional scores(visual analog scale for low back pain)in both groups.According to the visual analog scale score,the two groups of patients were divided into two subgroups:those with a visual analog scale score＜45 mm and those with a visual analog scale score＞45 mm,and the relationship between the difference in visual analog scale score and the parameters of paraspinal muscle tissue degeneration was analyzed.RESULTS AND CONCLUSION:(1)The percentage of fat infiltration in the multifidus muscle was higher in the degenerative lumbar spondylolisthesis group than in the isthmic spondylolisthesis group(P=0.003).(2)The percentage of fat infiltration in the multifidus muscle was significantly lower in patients with a visual analog scale score of＜45 mm than in patients with a visual analog scale score of＞45 mm in both groups(P=0.021,P＜0.001).(3)Patients in the isthmic spondylolisthesis group also showed a significantly lower percentage of fat infiltration in patients with visual analog scale score＜45 mm compared with those with visual analog scale score＞45 mm(P=0.002).(4)These results showed that there was a significant difference in paraspinal muscle tissue degeneration between isthmic spondylolisthesis patients and degenerative lumbar spondylolisthesis patients,and that degenerative lumbar spondylolisthesis patients demonstrated more severe paraspinal muscle degeneration compared to isthmic spondylolisthesis patients.In addition,the percentage of fatty infiltration of the multifidus muscle was relatively greater in those with higher pain scores in both groups of lumbar spondylolisthesis patients.

Alzheimer's disease(AD), a neurodegenerative disorder associated with aging, is the most prevalent form of dementia.As the aging population continues to expand, AD presents significant health and caregiving challenges for families and society, making it a pressing international public health concern.In recent years, numerous countries have implemented dementia prevention and treatment strategies that emphasize community-based comprehensive approaches.Currently, the community-based AD prevention and treatment model in China is still in the exploratory phase, with community efforts lacking organization.In alignment with China's action plan for advancing dementia prevention and treatment, and to achieve the strategic objective of "healthy aging, " this consensus is based on the principle of three-level prevention and is tailored to the characteristics of AD disease progression.It aims to develop a comprehensive prevention and treatment strategy for AD that is suitable for communities in China, providing technical guidance and support to establish a scientific basis for formulating community AD prevention and treatment models.

Objective To elucidate the role of let-7 in the pathogenesis of oral squamous cell carcinoma(OSCC)and its underlying molecular mechanism.Methods The expression of let-7 in human oral keratinocyte(HOK),OSCC tissues,and OSCC cells(CAL-27,SCC-25,and SCC-9)was detected by quantitative real-time PCR.Colony formation,scratch,Transwell,and flow cytometry assays were used to examine the effects of let-7 on the proliferation,migration,invasion,and apoptosis of SCC-25 cells.Western blotting was used to detect the expression of Wnt and β-catenin proteins.The correlation between let-7 expression and the clinicopathological cha-racteristics and prognosis of OSCC patients was analyzed.Results let-7 was downregulated in OSCC tissues and cells.let-7 over-expression effectively inhibited the proliferation,migration,and invasion of SCC-25 cells while promoting apoptosis by suppressing acti-vation of the Wnt/β-catenin pathway.let-7 expression was closely associated with tumor stage,lymph node metastasis,and patient survival status.Patients with low let-7 expression exhibited lower overall survival rate.Conclusion let-7 targets and regulates the Wnt/β-catenin pathway,thereby inhibiting proliferation,migration,and invasion of OSCC cells while promoting apoptosis.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.
