ObjectiveTo measure the distance from the surface of Fengfu （GV 16） to the deep important bony structures in children aged 4 to 8 years based on CT three-dimensional reconstruction technology， thereby providing imaging reference data for clinical acupuncture safe operations in terms of different age groups and needle insertion angles. MethodsCervical CT image data were collected from healthy children aged 4 to 8 years with five age groups （4-， 5-， 6-， 7-， 8-year-old groups）， 20 cases in each group. The images were imported into Mimics 21.0 software for three-dimensional reconstruction. The straight-line distances from the skin model surface of the Fengfu （GV 16） to the first underlying bony barrier （such as the lower edge of the occipital bone， the posterior arch of the atlas vertebra） were measured at intervals of 5° on both the transverse section （0° ± 35°） and the sagittal section （40° upward to 40° downward on the diagonal）. The correlation between the measured distance， age， and angle was analyzed. ResultsIn the transverse and sagittal sections， the measured distance from the skin surface to the underlying bone of Fengfu （GV 16） at each angle increased with age. In the transverse section， the increase was relatively small within the 0° to 20° angle range， whereas a more pronounced increase was observed when the angle exceeded 20°； at measurement angles of 30° to 35°， the distance of the skin surface to the bone at Fengfu （GV 16） in the 7- and 8-year-old groups was significantly greater than that in the 4-year-old group （P＜0.05）. In the sagittal section， the measured distance from the skin surface to the bone at Fengfu （GV 16） was shortest and changed greatly at oblique upward angles of 15° to 40° within each age group， and increased markedly at near-vertical angles of 0° to 10°； it was longest at oblique downward angles of -40° to -5° and showed relatively gradual changes. ConclusionThis study obtained the imaging distance data from Fengfu （GV 16） to the surrounding bony structures in children aged 4 to 8 years through three-dimensional modeling， finding that this distance has clear age and angle dependence， which can provide quantitative evidence for developing individualized and precise safe acupuncture schemes at Fengfu （GV 16） in pediatric clinical practice.

OBJECTIVES: To observe the effect of 4-(arylethynyl)-pyrrolo[2,3-d] pyrimidine (10b) on post-traumatic stress disorder (PTSD)-like behaviors and ERK1/2-SGK1 signaling pathway in mice. METHODS: C57BL/6 mouse models exposed to single prolonged stress (SPS) were treated with daily gavage of saline, 10b at low, moderate and high doses, or paroxetine for 14 days. The changes in PTSD-like behaviors of SPS mice with different treatments were observed using behavioral tests. Western blotting and immunofluorescence assay were used to detect the protein expression levels of mGluR5, p-ERK, and SGK1 in the hippocampus of the mice. Pathological changes in the liver and kidney tissues of the mice were examined using HE staining. Molecular docking and molecular dynamics analyses were employed to evaluate the binding stability between the compound 10b and mGluR5. RESULTS: Compared to the normal control mice, the SPS mice exhibited obvious PTSD-like behaviors with increased hippocampal expressions of mGluR5 and p-ERK proteins and decreased SGK1 protein expression. Compound 10b significantly ameliorated behavioral abnormalities in SPS mice, inhibited mGluR5 expression, and reversed the dysregulation of p-ERK and SGK1. No obvious liver or kidney toxicity was observed after 10b treatment. Molecular docking and dynamics studies demonstrated a stable interaction between 10b and mGluR5. CONCLUSIONS The compound 10b ameliorates PTSD-like behaviors induced by SPS in mice possibly by inhibiting mGluR5 expression to modulate the ERK1/2-SGK1 signaling pathway.

BACKGROUND:Currently,there have been studies on three-dimensional digitalization and visualization systems for adult acupoints,but there are not many reports on the visualization of pediatric acupoints based on real pediatric digital sectional anatomical datasets. OBJECTIVE:To design and develop a digital three-dimensional visualization system for children's neck acupoints,to provide a basis for acupuncture and moxibustion,meridian and acupoint science teaching,clinical practice,acupuncture manipulation practice,and acupuncture safety research,and to provide a basis for the development of children's acupoint simulation system. METHODS:Based on a real cross-sectional anatomical dataset of pre-school boys,a three-dimensional digital virtual anatomical model of the neck region of children and internal multi-organ three-dimensional reconstruction were completed using PhotoShop 2021 and Digihuman Reconstruction System software.A database of 11 acupoints was compiled,including Fengfu and Fengchi,using the Unity database language.A three-dimensional model of children's neck anatomy,acupoint database,and writing acupuncture operation codes were integrated in Unity3D software.A three-dimensional digital visualization system for children's neck acupoints was successfully created,which integrated simulation acupoint positioning,three-dimensional acupoint anatomy,acupuncture training,clinical teaching,and acupuncture safety research. RESULTS AND CONCLUSION:(1)This study was based on real child specimens.Manual layer by layer segmentation of cross-sectional images was used to ensure the accuracy of the three-dimensional model to the greatest extent possible.The 3D software Digihuman Reconstruction System was utilized to extract and save independent segmentation data.PhotoShop 2021 software was collaborated with to complete dozens of three-dimensional reconstruction anatomical models of the outer skin of the neck and its internal bone structure,cervical spinal cord,blood vessels and nerves,muscles,and ligaments in children.The basic morphology and overall contour integrity verification of each independent structure were completed in MeshLab software.The 3-material research 13.0 software was applied for final fine tuning and anatomical position confirmation,successfully simulating and restoring the true anatomical morphology of the neck of preschool children.(2)Based on and referring to the national standards of the People's Republic of China,a database of commonly used acupoints in children's neck region was collected and organized,including their names,meridians,positioning,local anatomy,needle insertion levels,acupuncture methods,acupuncture accidents and prevention,acupoint indications,and two-dimensional anatomical sectional images.(3)Unity3D software was employed to integrate the three-dimensional model of children's neck,acupuncture simulation operation,and acupoint database,and a three-dimensional digital children's neck acupoint acupuncture visualization system was successfully constructed.The system displayed information on children's neck acupoints,two-dimensional and three-dimensional anatomical structures,and achieved two-dimensional and three-dimensional acupuncture simulation functions and acupuncture safety research functions for children's neck acupoints.Based on the ultra-thin sectional anatomical dataset of real child specimens,the first three-dimensional digital and visualization system for acupoints in the neck region of children had been constructed.Compared with previous acupoint acupuncture systems,it is more in line with the anatomical and morphological development characteristics of Asian children and has high application value in the fields of acupuncture safety research,clinical teaching,and acupuncture simulation training.

Objective:To analyze the trend of the health literacy level of Chinese residents from 2012 to 2023 and predict the health literacy level from 2024 to 2027.Methods:The study collected data on the health literacy surveillance of Chinese residents from 2012 to 2023. The Joinpoint regression model was used to calculate the average annual percent change (AAPC) and analyze the trend. The interrupted time series analysis with Prais-Winsten transformed generalized least squares estimation was employed to investigate the impact of the"Healthy China 2030" policy on residents′ health literacy levels. Joinpoint regression, autoregressive integrated moving average model and grey forecasting models were established to select the optimal model for forecasting health literacy levels from 2024 to 2027.Results:The results showed that the health literacy level of Chinese residents increased from 8.80% in 2012 to 29.70% in 2023 (AAPC=11.65%, P<0.05). The health literacy level of urban and rural residents increased from 11.79% and 7.13% in 2012 to 33.25% and 26.23% in 2023, respectively (AAPC=9.57% and 12.60%, both P<0.05). Rural (1.59% per year) saw a lower average annual increase than urban (1.79% per year), widening the urban-rural health literacy gap. All aspects of health literacy, including basic knowledge and concepts, healthy lifestyles and behaviors, and health skills, showed an upward trend. The literacy level of six health issues—safety and first aid, scientific health views, health information, infectious disease prevention, chronic disease prevention, and basic medical care—also exhibited rising trends. Interrupted time series analysis indicated a significant further increase in the health literacy level of Chinese residents after the implementation of the "Healthy China 2030" policy, with the growth rate increasing from 0.615% per year before implementation to 2.655% per year afterwards. The Joinpoint regression model showed superior predictive performance compared to autoregressive integrated moving average model and grey forecasting models. The prediction results suggested a continued upward trend in the health literacy level from 2024 to 2027, reaching 32.68%, 35.62%, 38.84%, and 42.34%, respectively. Conclusion:From 2012 to 2023, the overall and various aspects of health literacy among Chinese residents show a continuous upward trend. This study predicts that the level of residents′ health literacy will continue to rise by 2027.

Objective To investigate the role of additional platelet protein kinase C epsilon(PKCε)assay in risk stratification and additional diagnostic testing in elderly patients with acute chest pain and normal hypersensitive cardiac troponin I(hs-cTnI)level.Methods A prospective trial was conducted on 220 consecutive elderly patients with angina-like acute chest pain and normal hs-cTnI level in our hospital from April 2022 to April 2023.According to whether major adverse cardiovascular events(MACE)occurred during the 1-year follow-up period,they were assigned in-to MACE group(24 cases)and non-MACE group(196 cases).Their general clinical data and platelet PKCε expression were compared between the two groups.Kaplan-Meier survival curve was plotted to analyzed the event-free time between the platelet PKCε expression＜2.05％group and the≥2.05％group.Multivariate Cox regression analysis was used to investigate the impact of baseline data on the occurrence of MACE during the 1-year follow-up period.Decision tree model was employed to analyze the influencing factors for MACE.Results During 1-year follow-up,24 patients(10.91％)developed MACE.The platelet PKCε expression was significantly higher in the MACE group than the non-MACE group[9.25％(6.60％,15.25％)vs 1.70％(0.80％,3.25％),Z=-7.596,P＜0.01].Kaplan-Meier survival curve analysis showed that the patients in the PKCε＜2.05％group had no events within 360 d,while those in the ≥2.05％group had an average event-free time of 297.13±12.77 d,with a statistical difference(log rank Chi-square=27.051,P=0.000).Multivariate Cox regression analysis showed that highly suspicious angina,hs-cTnI and platelet PKCε were independent risk factors for MACE within 1 year of follow-up(HR=3.011,95％CI:1.049-8.641,P=0.040;HR=1.216,95％CI:1.044-1.418,P=0.012;HR=1.160,95％CI:1.104-1.218,P=0.000).In the decision tree model,the 1-year incidence of MACE was notably higher in the platelet PKCε≥2.05％group than the＜2.05％group(P=0.011).The probability of severe coronary artery stenosis or myocardial ischemia in the platelet PKCε≥2.05％group was remarkably higher than the＜2.05％group(P=0.006).Conclusion In elderly patients suffering from acute chest pain with normal hs-cTnI level,additional platelet PKCε detection appears to have a good prognostic gain.

Objective:This study utilizes data from the 2021 Chinese Longitudinal Healthy Longevity and Happy Family Survey(CLHLS-HF)to examine the current status of Long-Term Care Insurance(LTCI)implementation and to identify the factors influencing whether disabled elderly individuals receive formal care services.The study aims to provide policy recommendations to enhance the effectiveness and equity of the system.Methods:In this cross-sectional study, a sample of 1 447 older participants with dependency, residing in LTCI pilot areas and meeting the inclusion criteria from the 2021 CLHLS-HF, was selected.Chi-square tests and binary logistic regression analyses were employed to explore the factors influencing the receipt of formal care by dependent older individuals.Results:Among the 1 447 participants, there were 496 males with an average age of 92 years(SD 9)and 951 females with an average age of 95 years(SD 9). Of these, 701 received formal care.The logistic regression analysis revealed that factors influencing the receipt of formal care included urban residence( OR=2.237, 95% CI: 1.675-2.987, P<0.001), residing in the eastern region( OR=2.907, 95% CI: 1.747-4.837, P<0.001), living in the western region( OR=3.132, 95% CI: 1.816-5.501, P<0.001), having no children( OR=2.478, 95% CI: 1.108-5.540, P=0.027), and the degree of disability, with severe disability being more likely to receive care compared to mild( OR=0.497, 95% CI: 0.388-0.637, P<0.001)and moderate disabilities( OR=0.589, 95% CI: 0.433-0.801, P=0.001). Conclusions:Dependent older individuals in the eastern and western regions, particularly those without children or with severe disabilities, are more likely to receive formal care through the LTCI system.However, there are substantial inequities in LTCI coverage among individuals with varying degrees of disability.To enhance the effectiveness of the LTCI system, greater efforts should be directed towards economically disadvantaged regions and older individuals with mild to moderate disabilities, thereby ensuring better protection for the disabled population.

OBJECTIVE: To observe the effects of Tongdu Tiaoshen acupuncture (for unblocking the obstruction in the governor vessel and regulating the spirit) on depression-like behavior and the hippocampal Endophilin A1/reactive oxygen species (ROS) pathway in the chronic unpredictable mild stress (CUMS) model rats, and explore the mechanism of this therapy for depression. METHODS: Forty-eight male SD rats of SPF grade were randomly divided into a normal group (n=12) and a modeling group (n=36). In the modeling group, CUMS was performed to establish depression model. The successfully-modeled rats were randomized into a model group, a Tongdu Tiaoshen acupuncture group (referred to as the acupuncture group), and a fluoxetine group, with 12 rats in each group. In the acupuncture group, "Baihui" (GV20), "Shenting" (GV24), "Shuigou" (GV26) and "Dazhui" (GV14) were stimulated with acupuncture. This intervention measure was delivered once a day, continuously for 6 days; it was discontinued on day 7 and was completed in 28 days. In the fluoxetine group, intragastric administration was done with fluoxetine solution (2.1 mg/kg), once a day, and for 28 consecutive days. Before and after modeling, and after intervention completion, the body mass, sucrose preference rate and the total distance of movement and the boxes of horizontal crossing in the open field experiment were observed in each group. After intervention, using HE staining, the hippocampal neuron morphology was observed; using Nissl staining, the hippocampal Nissl body number was counted. The hippocampal mitochondria was observed under transmission electron microscopy. The average fluorescence intensity of ROS in hippocampal was determined using flow cytometry. With Western blot method, the protein expression of Endophilin A1, growth associated protein 43 (GAP-43), and brain-derived neurotrophic factor (BDNF) in hippocampal was detected; and with RT-qPCR method, the mRNA expression of Endophilin A1, GAP-43, and BDNF was recorded. Using the immunofluorescence, the average fluorescence intensity of Endophilin A1, GAP-43, and BDNF in hippocampal tissue was determined. RESULTS: Compared with the normal group, in the model group, the body mass, sucrose preference rate, and the total distance of movement and the boxes of horizontal crossing in the open field experiment decreased (P<0.01); the hippocampal neuronal structure was unclear, the matrix was relatively loose, and the number of Nissl body decreased (P<0.01); mitochondrial structure was disarranged, the outer membrane was ruptured, mitochondrial cristae was irregular or missed; the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue increased (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and its average fluorescence intensity decreased (P<0.01). Compared with the model group, the acupuncture group and the fluoxetine group showed the increase in body mass, sucrose preference rate, the total distance of movement and the boxes of horizontal crossing in the open field experiment (P<0.05, P<0.01); the hippocampal neuronal structure became relatively clear, the matrix was relatively dense, and the number of Nissl body was elevated (P<0.01); mitochondrial structure got normal and disarranged slightly, the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue were reduced (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and the average fluorescence intensity rose (P<0.01, P<0.05). Compared with the fluoxetine group, the acupuncture group presented the increase in the average fluorescence intensity of ROS, the protein expression and the average fluorescence intensity of Endophilin A1, the protein expression of GAP-43 and the mRNA expression of BDNF (P<0.01, P<0.05), and the decrease of the protein expression and the average fluorescence intensity of BDNF, the mRNA expression of Endophilin A1, and the average fluorescence intensity of GAP-43 (P<0.01, P<0.05). CONCLUSION Tongdu tiaoshen acupuncture alleviates depression-like behaviors in CUMS model rats and protects hippocampal neurons, which may be related to suppressing Endophilin A1/ROS signaling pathway and attenuating oxidative stress reactions.

Objective:To explore the efficacy and surgical seletion or timing for elderly patients(≥85 years) with inguinal hernia.Methods:A retrospective analysis was conducted on clinical data of 323 patients aged ≥ 85 years who underwent surgical treatment for inguinal hernia admitted to the Department of General Surgery of East China Hospital Affiliated to Fudan University from Jan 2020 to Dec 2024.There were 308 males (95.36%) and 15 females (4.64%), with an average age of (87.83 ± 1.91) years. The ASA classification included 15 cases of grade Ⅰ, 209 cases of grade Ⅱ, 97 cases of grade Ⅲ, and 2 cases of grade Ⅳ.Results:Among the 323 patients, there were 20 bilateral hernia cases and 303 unilateral cases. Ninety-seven cases were of scrotal hernia. Surgical methods included 11 TAPP cases, 10 TEP cases, 297 Lichtenstein cases, 3 open suture repair and 2 laparoscopic suture repair. Four cases underwent intestinal resection and in two cases enterostomy was performed. The median follow-up after surgery was 3 months. Hernia recurrence was found in 2 cases, seroma in 14 cases, chronic pain in 2 cases, SSI in 11 cases, intestinal obstruction in 1 case, urinary retention in 3 cases, pulmonary infection in 9 cases, urinary tract infection in 2 cases, cardiovascular and cerebrovascular accidents in 2 cases. The incidence of postoperative complications in the emergency group was significantly higher than that in the elective group. Three deaths occurred within 30 days after surgery, all of which were in the emergency group.Conclusions:Selective inguinal hernia repair is safe and effective for over 85 year old patients with inguinal hernia. The incidence of emergency surgical complications and mortality is significantly increased. Lichtenstein surgery under local anesthesia or regional block anesthesia is the preferred method.

Objective To investigate the relationship between the mRNA expression levels of colony stimulating factor 2 receptor subunit beta CSF2RB and granase A(GZMA)in peripheral blood mononuclear cells(PBMC)of patients with acute myocardial infarction(AMI)and ventricular remodeling after percutaneous coronary intervention(PCI).Methods A total of 161 AMI patients admitted to the First Affiliated Hospital of Hebei North University from February 2022 to August 2023 were selected as the study objects,and were further divided into non-remodeling group(n=105)and remodeling group(n=56)according to whether ventricular remodeling was possible.A total of 85 patients with coronary heart disease who did not have myocardial infarction were taken as control group.The clinical data of patients were collected,and the expression levels of CSF2RB and GZMA mRNA in peripheral blood mononuclear cells were detected by real-time fluorescence quantitative PCR.Cardiac structural parameters were detected by echocardiography,and the relationship between CSF2RB and GZMA mRNA levels and cardiac structural parameters was analyzed by Pearson correlation.The influencing factors of ventricular remodeling in AMI patients were analyzed by univariate and Logistic regression,and P<0.05 was considered statistically significant.Results The mRNA expression of CSF2RB(1.15±0.28 vs 1.80±0.37),GZMA(0.85±0.16 vs 1.15±0.26),Cys C and Hcy levels were compared between the two groups,and the differences were statistically significant(t=-39.002～-4.854,all P<0.05).The follow-up was up to August 2024.Among 161 AMI patients who underwent PCI,56 cases had ventricular remodeling.The expression level of CSF2RB mRNA(1.85±0.31),GZMA mRNA(1.27±0.29)in the reconstructed group were significantly higher than that in the non-reconstructed group(1.71±0.34,1.12±0.30),and the differences were statistically significant(t=2.564,3.057,all P<0.001).LAD,LVEDD,LVPWTd and IVST in the postoperative reconstruction group were higher than those in the non-reconstruction group(t=11.247～26.008),and LVEF was lower than that in the reconstruction group(t=-15.271),with statistical significance(all P<0.001).The level of CSF2RB and GZMA in AMI patients was positively correlated with LAD,LVEDD,LVPWTd and IVST(rCSF2RB mRNA=0.657～0.754,rGZMA mRNA=0.512～0.745),and negatively correlated with LVEF(r=-0.684,-0.754),with statistical significance(all P<0.05).There was a statistically significant differences in the levels of Cys C and Hcy between the reconstructed group and non-reconstructed group after the use of aldehyed steroid receptor antagonsts(t=5.495,20.710,30.906,all P<0.05).Logistic regression analysis showed that CSF2RBmRNA＞1.79,GZMAmRNA＞1.18,Hcy＞20.15μmol/L and no use of aldosterol receptorantagonists were independent risk factors for ventricular remodeling in AMI patients.LVEF＞58.11%was an independent protective factor for ventricular remodeling in AMI patients(Wald χ2=1.137～3.206,P<0.05).Conclusion The expression levels of CSF2RB and GZMA in PBMC of AMI patients were significantly increased.CSF2RB and GZMA are independent risk factors for postoperative ventricular remodeling in patients with AMI,and can be used as potential diagnostic markers for ventricular remodeling after acute myocardial infarction.
