ObjectiveTo develop a scale for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease （NAFLD） that combines disease and syndrome and has the characteristics of traditional Chinese medicine （TCM）. MethodsAn item pool was established for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease （NAFLD） with reference to the guideline for developing international scales. A clinical survey was conducted among the outpatients and inpatients who were diagnosed with NAFLD and had the syndrome of internal retention of dampness and turbidity in Department of Hepatology and Spleen-Stomach， The First Affiliated Hospital of Henan University of Chinese Medicine， from June to August， 2023， and the items were screened based on the classical test theory and the item response theory. An expert questionnaire was developed， and expert discussions were conducted using the Delphi method to identify the items for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD. Finally， the scale was given scientific scores. ResultsA preliminary item pool was established， with 16 primary items and 22 secondary items， and it was divided into the two dimensions of disease and syndrome type. Clinical pre-survey suggested to retain 9 primary items and 14 secondary items， while the Delphi expert questionnaire recommended to retain 11 primary items and 15 secondary items， and tongue manifestation and pulse manifestation were no longer used for assessing the severity of syndrome. After hierarchical analysis and scientific assignment of scores， the scale for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD had a total score of 123 points and 9 important items， i.e.， discomfort in the hypochondrium， abdominal fullness and distension， obesity， heaviness of the head and body， loose stool， anorexia， coughing up phlegm， nausea with a tendency to vomit， and lethargy. ConclusionA preliminary scale is established for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD， which fills the gap in this research field and provides a basis for further clinical application.

Objective: To establish a database of CD36 antigen-negative donors through large-scale screening of apheresis platelet donors in Shenzhen for CD36 deficiency subtypes and blood group distribution, and to assess clinical demand and blood supply capacity through a retrospective analysis of the apheresis platelet donation volumes from 2019 to 2023. Methods: Flow cytometry with fluorescent CD36 monoclonal antibodies was employed to screen platelet/monocyte CD36 deficiency (Type I and Ⅱ), and statistical analyses were conducted using SPSS software (version 27.0). Results: Among 11 603 apheresis platelet donors, 248 (2.14%) exhibited CD36 deficiency, comprising 51 type Ⅰ (0.43%, 51/11, 603) and 197 type Ⅱ (1.70%, 197/11, 603) cases, with significant difference (P<0.001). CD36 deficient platelets were mainly distributed in blood group B (2.28%, 902.3/39 602.1) and AB (2.14, 269/12 544.5), significantly exceeding those in blood group A (1.43%, 667/46 508.4) and O (1.64%, 1 000/60 965.6) (P<0.001). The proportion of donors with 10-100 U from CD36 deficient donors was the highest (51%, 1 446.4/2 838.3). Conclusion: Sustained screening for CD36-deficient donors is recommended to meet the clinical transfusion needs for immunized patients and those requiring antigen-negative products. Regional resource-sharing mechanisms should be optimized to maximize utilization of CD36-deficient platelet inventories.

Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.

Objective To investigate the risk factors for the development of advanced liver fibrosis by analyzing the clinical features of patients with in nonalcoholic fatty liver disease(NAFLD)and advanced liver fibrosis,and to establish a nomogram model for predicting the risk of advanced liver fibrosis.Methods A retrospective analysis was performed for the clinical data of 406 NAFLD patients who attended The First Affiliated Hospital of Henan University of Chinese Medicine from January 2022 to October 2023,and according to whether liver stiffness measurement(LSM)measured by FibroScan was≥11.0 kPa,the patients were divided into advanced liver fibrosis group with 65 patients and non-advanced liver fibrosis group with 341 patients.Related data were collected,including general information,laboratory markers,and medical history.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.A multivariate Logistic regression analysis was used to identify independent risk factors,and a nomogram model was established based on these factors.The receiver operating characteristic(ROC)curve was used to evaluate the discriminatory ability of the nomogram model,and the calibration curve was used to evaluate its effectiveness.Results The univariate analysis showed that there were significant differences between the advanced liver fibrosis group and the non-advanced liver fibrosis group in age,controlled attenuation parameter(CAP),total bilirubin,direct bilirubin(DBil),indirect bilirubin,globin,alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase(ALP),gamma-glutamyl transpeptidase(GGT),glucose,body mass index(BMI),and history of diabetes(all P<0.05).The multivariate Logistic regression analysis showed that CAP(odds ratio[OR]=1.015,95%confidence interval[CI]:1.006-1.024,P=0.010),DBil(OR=1.345,95%CI:1.139-1.590,P=0.001),ALP(OR=1.019,95%CI:1.008-1.029,P=0.001),GGT(OR=1.004,95%CI:1.000-1.008,P=0.035)and BMI(OR=1.240,95%CI:1.137-1.353,P=0.001)were independent risk factors for the development of advanced liver fibrosis in NAFLD.A nomogram model was established based on the results of the multivariate Logistic regression analysis.The ROC curve analysis showed that this nomogram model had an area under the ROC curve of 0.841(95%CI:0.791-0.891)in predicting the development of advanced liver fibrosis in the NAFLD population,and the calibration curve showed a good degree of fitting between the observed and predicted values for the development of advanced liver fibrosis.Conclusion Elevated levels of CAP,BMI,DBil,ALP,and GGT are independent risk factors for advanced liver fibrosis in NAFLD.The nomogram model established based on these factors has good predictive performance and a certain value in predicting advanced liver fibrosis.

Nonalcoholic fatty liver disease(NAFLD)is a common metabolic disease,and in recent years,the incidence rate of NAFLD is gradually increasing,which seriously threatens human health.As a traditional treatment method,external therapy of traditional Chinese medicine(TCM)has shown unique advantages and potential in the treatment of NAFLD.This article provides a detailed analysis of the TCM understanding of the etiology and pathogenesis of NAFLD,the application of TCM external therapy in clinical research,and the research on its therapeutic mechanism,in order to provide reference and guidance for further research in this field.

Objective To investigate the impact of O-linked β-N-acetylglucosamine(O-GlcNAc)modification levels in the amygdala on stress resilience.Methods A restraint stress model was established in male C57BL/6J mice by confining them for 24 hours,followed by by 7days of rest.Behavioral assays,including the tail suspension test,forced swimming test and fear conditioning test,were conducted.Subsequently,the mice were euthanized,and the hippocampus,cortex,and amygdala were isolated.O-GlcNAc modification levels in these brain regions were assessed using enzyme-linked immunosorbent assay(ELISA).Using stereotaxic brain injection techniques,the O-GlcNAcase(OGA)inhibitor,O-GlcNAc transferase(OGT)inhibitor,and OGA and OGT adeno-associated viruses were administered to regulate O-GlcNAc levels in the amygdala before their effects on stress-related behavior were observed.Results The restraint stress group showed significantly increased anxiety,depressive-like behavior,and impaired memory.Concomitantly,O-GlcNAc levels in the amygdala were significantly decreased post-stress and were negatively correlated with behavioral performance.Mice with higher stress resilience exhibited significantly higher levels of O-GlcNAc in the amygdala than more sensitive ones.Upregulation of O-GlcNAc levels in the amygdala via Thiamet-G or adeno-associated virus-O-GlcNAc transferaseinjections increased O-GlcNAc levels,alleviated depressive-like behavior and enhanced stress resilience.In contrast,downregulation of O-GlcNAc levels through OSMI-1 or adeno-associated virus-O-GlcNAcase injections reduced the O-GlcNAc levels,exacerbated depressive-like behavior and reduced resilience to stress.Conclusion O-GlcNAc modification levels in the amygdala play a critical role in regulating stress resilience following restraint stress in mice.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

The overall health condition of patients significantly affects the diagnosis,treatment,and prognosis of endodontic diseases.A systemic consideration of the patient's overall health along with oral conditions holds the utmost importance in determining the necessity and feasibility of endodontic therapy,as well as selecting appropriate therapeutic approaches.This expert consensus is a collaborative effort by specialists from endodontics and clinical physicians across the nation based on the current clinical evidence,aiming to provide general guidance on clinical procedures,improve patient safety and enhance clinical outcomes of endodontic therapy in patients with compromised overall health.

Digital guided therapy (DGT) has been advocated as a contemporary computer-aided technique for treating endodontic diseases in recent decades. The concept of DGT for endodontic diseases is categorized into static guided endodontics (SGE), necessitating a meticulously designed template, and dynamic guided endodontics (DGE), which utilizes an optical triangulation tracking system. Based on cone-beam computed tomography (CBCT) images superimposed with or without oral scan (OS) data, a virtual template is crafted through software and subsequently translated into a 3-dimensional (3D) printing for SGE, while the system guides the drilling path with a real-time navigation in DGE. DGT was reported to resolve a series of challenging endodontic cases, including teeth with pulp obliteration, teeth with anatomical abnormalities, teeth requiring retreatment, posterior teeth needing endodontic microsurgery, and tooth autotransplantation. Case reports and basic researches all demonstrate that DGT stand as a precise, time-saving, and minimally invasive approach in contrast to conventional freehand method. This expert consensus mainly introduces the case selection, general workflow, evaluation, and impact factor of DGT, which could provide an alternative working strategy in endodontic treatment.
