Chronic atrophic gastritis （CAG）， a premalignant gastric condition， represents a critical stage in inflammation-cancer transformation. In this pathological process， mitochondrial damage serves as a key mediator in the inflammation-driven transformation of normal gastric mucosal epithelial cells into gastric cancer cells， while the dysregulation of the reactive oxygen species （ROS）/NOD-like receptor protein 3 （NLRP3） axis plays a key role in perpetuating the vicious cycle of inflammation-mitochondrial damage. The classical theory of traditional Chinese medicine （TCM）， vigorous fire consuming Qi， aptly encapsulates this pathological feature. The essence of this theory lies in the struggle between pathogenic and vital factors， wherein vigorous fire shares similarities with chronic inflammation and may be regarded as a driving force behind inflammation-cancer transformation. Qi reflects the mitochondrial function， and consuming Qi signifies structural and functional impairment of mitochondria. Thus， this theory accurately summarizes the pathological characteristics of inflammation-mitochondrial damage during CAG progression. Building upon this theoretical framework， the theory of vigorous fire consuming Qi provides a holistic understanding of CAG pathogenesis. Reviewing the clinical expertise of TCM master YANG Chunbo in treating spleen-stomach disorders， this paper further elucidates its therapeutic implications： modulating systemic inflammatory responses to restore gastric mucosal homeostasis and targeting mitochondrial damage as a pivotal intervention to delay CAG progression. Clinically， achieving dynamic equilibrium between fire and Qi is essential， mitigating excessive inflammation without compromising vital Qi， while reinforcing Qi without exacerbating pathological fire. This approach offers novel insights for developing preventive and therapeutic strategies against CAG.

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 investigate the correlation between serum homocysteine(Hcy),hemoglobin(HGB)and hematocrit(HCT)levels and the severity of condition and inflammatory factor levels in patients with chronic atrophic gastritis.Methods A total of 122 patients with chronic atrophic gastritis admitted to a hospital from January 2022 to December 2023 were selected as the disease group,and the disease group was di-vided into mild group(n=63)and severe group(n=59)according to pathological grades,and 106 healthy volunteers who underwent physical examination in a hospital during the same period were selected as the con-trol group.Clinical data of patients were collected and binary Logistic regression analysis was performed to an-alyze the factors affecting the severity of patients'condition,and Pearson correlation analysis was used to ana-lyze the correlation between Hcy,HGB,HCT and the levels of inflammatory factors.Receiver operating char-acteristic(ROC)curve was drawn to analyze the diagnostic value of Hcy,HGB and HCT on the severity of patients'condition.Results Compared with the control group,the serum Hcy level in the diseased group was increased,the serum HGB and HCT levels were decreased,the difference was statistically significant(P<0.05).Compared with the mild group,the serum Hcy level in the severe group was increased,the HGB and HCT levels were decreased,and the difference was statistically significant(P<0.05).Compared with mild group,the levels of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)and interleukin(IL)-6 in se-vere group were increased,and the levels of IL-10 were decreased,with statistical significance(P<0.05).Bi-nary Logistic regression analysis showed that Hcy and CRP were the risk factors affecting the severity of pa-tients'condition(P<0.05),and HCT,HGB and IL-10 were the protective factors affecting the severity of pa-tients'condition(P<0.05).Hcy was positively correlated with CRP,TNF-α and IL-6,and negatively correla-ted with IL-10(P<0.05).HGB and HCT were negatively correlated with CRP,TNF-α and IL-6,and posi-tively correlated with IL-10(P<0.05).ROC curve analysis showed that the area under the curve of serum Hcy,HGB,HCT and the combined diagnosis of the severity of patients'condition were 0.834,0.814,0.822 and 0.923,respectively,and the combined diagnosis value of the three was significantly better than that of Hcy(Z=2.519,P=0.012),HGB(Z=2.660,P=0.008)and HCT(Z=2.596,P=0.009)alone.Conclusion The increase of serum Hcy and the decrease of serum HGB and HCT in patients with chronic atrophic gastritis are correlated with the severity of the patient's condition and the level of inflammatory factors.The combined de-tection of the three can be used for the diagnosis of the severity of chronic atrophic gastritis.

Objective:To explore the mechanism that leads to the formation of medical insurance fraud,in order to propose countermeasures and suggestions for preventing medical insurance fraud.Methods:Taking 30 provinces and cities in China as research objects,Fuzzy-Set Qualitative Comparative Analysis and Necessary Condition Analysis are applied to explore the configuration paths that lead to medical insurance fraud.Results:A single factor does not constitute a necessary condition for a high incidence of Medicare insurance fraud.There are four grouping paths that lead to a high incidence of Medicare insurance fraud,namely,the dominant factor of poor medical insurance operation status,the dual auxiliary factor of low informationization level and weak regulatory mechanism under the dominant status of poor medical insurance operation,the auxiliary pathway of low economic level under the dual dominance factors of poor medical insurance operation and low informationization level,and the three dominant factors of poor medical insurance operation as well as weak regulatory mechanism and low economic level.Conclusion:Medical insurance fraud is caused by multiple factors,therefore the following prevention strategies are proposed,focusing on rectifying and breaking through difficult problems,strengthening regulatory effectiveness through departmental linkage,enhancing regulatory accuracy through technological empowerment,and improving long-term mechanisms by addressing both symptoms and root causes.

The intentional suppression of memory retrieval to achieve directed forgetting is a crucial adaptive function for individuals.In psychotherapy theory,such active forgetting is often associated with trauma,where in individuals actively exclude trauma-related negative memories from awareness to reduce unpleasant emotional experiences.Based on the"go/no-go"task paradigm,researchers developed the"think/no-think"(TNT)paradigm,and through this paradigm,they have revealed that individuals can achieve active forgetting by suppressing the retrieval of previously encoded memories.Patients with depressive disorders often exhibit cognitive processing biases toward negative information.Compared to healthy populations,they demonstrate impaired memory retrieval suppression in TNT tasks,especially for negative memories.This deficit in retrieval suppression makes negative memories more susceptible to reactivation,triggering negative emotions and perpetuating a vicious cycle.Relevant neuroimaging results show that during memory retrieval suppression,the lateral prefrontal lobe exerts top-down control through relevant regions to modulate memory processing of hippocampus,thereby blocking intentional recall.Abnormalities in the prefrontal-hippocampal inhibitory pathway and hyperactivation of the amygdala in depressed individuals may be the underlying neural mechanisms for their impaired suppression of negative memory retrieval.This article provides a review focusing on the negative memory bias exhibited in depressed individuals in the TNT task and the exploration of its underlying mechanisms.It summarizes relevant research findings with the aim of offering references for the development of precise psychotherapies and novel approaches targeting the improvement of specific symptom clusters.

Dysfunction of the interoceptive system is recognized as an important component of clinical symptoms, including anxiety, depression, psychosis, and other mental disorders. Non-invasive neuromodulation is an emerging clinical intervention approach, and over the past decade, research on non-invasive neuromodulation aimed at regulating interoception has rapidly developed. This review first outlines the pathways of interoceptive signals and assessment methods, then summarizes the interoceptive abnormalities in psychiatric disorders and current studies for non-invasive neuromodulation targeting interoception, including intervention modes, target sites, interoceptive measures, and potential neurobiological mechanisms. Finally, we discuss significant research challenges and future directions.

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.
