This article discusses the important role and practical experience of Guangxi Zhuang Autonomous Region as a bridgehead between China and the Association of Southeast Asian Nations (ASEAN) in the joint prevention and control of cross-border infectious diseases between China and Vietnam. The cross-border transmission of infectious diseases has been effectively managed in Guangxi Zhuang Autonomous Region through a package of strategies, including government leadership, construction of the joint prevention and control mechanism, establishment of dialogue platforms, collaboration of scientific researches, and personnel exchange and training; however, there are still challenges. Further deepening of collaboration is required to meet future needs for infectious disease prevention and control.

OBJECTIVE: To explore the anatomical parameters of the cervical uncinate process "inflection point" through cervical CT angiography (CTA) and MRI measurements, offering a reliable and safe anatomical landmark for anterior cervical decompression surgery. METHODS: A retrospective analysis was conducted on the cervical CTA and MRI imaging data of normal adults who met the selection criteria between January 2020 and January 2024. The CTA dataset included 326 cases, with 200 males and 126 females, aged 22-55 years (mean, 46.7 years). The MRI dataset included 300 cases, with 200 males and 100 females, aged 18-55 years (mean, 43.7 years). Based on the CTA data, three-dimensional models of C ₃-C ₇ were constructed, and the following measurements were obtained from the superior view: uncinate process "inflection point" to vertebral artery distance (UIVD), uncinate process tip to vertebral artery distance (UTVD), uncinate process "inflection point" to "inflection point" distance (UID), uncinate process long-axis to sagittal angle (ULSA), and uncinate process "inflection point" to transverse foramen-sagittal angle (UITSA). From the anterior view, the anterior uncinate process to sagittal angle (AUSA) was measured. From the posterior view, the posterior uncinate process to sagittal angle (PUSA) was measured. Based on the MRI data, uncinate process "inflection point" to dural sac distance (UIDD) and dural sac width (DSW) were measured. The trends in measurement parameters of C ₃-C ₇ were observed, and the differences in measurement parameters between genders and between the left and right sides of the same segment were compared, as well as the difference in UID and DSW within the same segment was compared. RESULTS: The measurement parameters from C ₃ to C ₇ in the CTA data showed a general increasing trend, with no significant difference between the left and right sides within the same segment ( P>0.05). The UIVD, UTVD, and UID were greater in males than in females, with significant differences observed in the UIVD and UTVD at C ₃ and C ₆ and UID at C ₃, C ₆, and C ₇ ( P<0.05). The MRI measured DSW showed a general increasing trend from C ₃ to C ₇, and the DSW at C ₆ was greater in females than in males, with a significant difference ( P<0.05). The UIDD showed a gradual decreasing trend, with the smallest value at C ₆. There was no significant difference between males and females or between the left and right sides within the same segment ( P>0.05). The UID was greater than the DSW at C ₃-C ₇, and the differences were significant ( P<0.05). CONCLUSION The uncinate process "inflection point" is a constant anatomical structure located at the anteromedial aspect of the uncinate process tip and laterally to the dural sac. It maintains a certain safe distance from the vertebral artery. As a decompression landmark in anterior cervical spine surgery, it not only ensures surgical safety but also guarantees complete decompression.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To assess the presence of chemotherapy-induced abnormal myocardial perfusion using SPECT myocardial perfusion imaging (MPI) in patients with malignant hematologic diseases before hematopoietic stem cell transplantation (HSCT), and to explore its predictive value for mid-to-long-term mortality risk after transplantation.Methods:From March 2016 to August 2022, 139 patients with malignant hematologic diseases (80 males, 59 females; age (45.7±13.0) years) who underwent resting MPI to assess the presence of chemotherapy-induced abnormal myocardial perfusion before HSCT at the First People′s Hospital of Changzhou were prospectively included. Baseline-data were collected and patients were followed up for mid-to-long-term (≥100d) adverse outcomes after transplantation. Overall survival (OS) of each patient was recorded. The χ2 test and independent-sample t test were used for data analysis. Cox regression analysis was utilized to identify independent risk factors affecting OS. Kaplan-Meier method and log-rank test were used for survival analysis. Results:The median follow-up time of 139 patients was 41.6(19.5, 65.6) months, with all-cause mortality of 28.8%(40/139), and the cardiovascular mortality was 42.5%(17/40). The prior cardiotoxic therapies rate (anthracycline dose ≥250mg/m 2) was higher in the death group compared to that in the survival group (15.0% (6/40) vs 5.1% (5/99); χ2=3.87, P=0.049). Pre-transplant abnormal myocardial perfusion rate was also higher in the death group compared to that in the survival group (55.0%(22/40) vs 22.2%(22/99); χ2=15.19, P<0.001). But pre-transplant left ventricular ejection fraction (LVEF) was lower in the death group compared to that in the survival group ((60.4±5.2)% vs (62.9±3.9)%; t=-3.07, P=0.003). Cox multivariate regression analysis showed that the abnormal myocardial perfusion indicated by MPI before transplantation was an independent risk factor affecting OS after HSCT in patients with malignant hematologic diseases (hazard rate ( HR)=2.70, 95% CI: 1.33-5.46, P=0.006). Kaplan-Meier analysis showed the 1-, 2-, 5-year OS rates of patients with the abnormal myocardial perfusion and the normal myocardial perfusion were 73.5%, 69.1%, 49.2% and 94.6%, 89.9%, 81.6%, respectively, with significant difference ( χ2=17.01, P<0.001). Conclusions:Patients with abnormal myocardial perfusion detected by MPI before HSCT for malignant hematologic diseases have a poorer prognosis, characterized by lower post-transplantation OS rates. The utilization of MPI for assessing abnormal myocardial perfusion before transplantation in patients with malignant hematologic diseases can aid in predicting the mid-to-long-term mortality risk after transplantation.

Objective:To analyze the epidemiological characteristics and trend of acute hemorrhagic conjunctivitis (AHC) in China from 2015 to 2022, and to provide evidence for the adjustment of prevention and control strategies and measures for AHC.Methods:The case data of AHC reported by national notifiable disease information system from 2015 to 2022 were collected, and descriptive analysis method were used to analyze the population distribution characteristics, temporal epidemiological trends and spatial clusters of AHC in China.Results:From 2015 to 2022, the incidence of AHC in China ranged from 1.85/100 000 to 2.97/100 000, with a fluctuating downward trend. The average annual percent change (AAPC) was -4.91 (95% CI: -7.74 to -2.00, P<0.05), with an annual percent change (APC) of 2.73 (95% CI: -2.34 to 8.06, P=0.189) for 2015—2019 and an APC of -14.23 (95% CI: -21.78 to -5.94, P<0.05). The age-specific incidence rate was highest in children aged 0-4 years (fluctuating between 4.69 and 5.67/100 000 from 2015 to 2019; It decreased significantly during 2020—2022, fluctuating between 1.93 and 2.72 per 100 000).The proportion of cases in children at 0-4 years of age showed a fluctuating downward trend from 8.68% in 2015 to 3.76% in 2020, with an increase in 2021—2022 to 5.74%. After 2020, the proportion of the population aged 60 years and above has increased, reaching 33.59% in 2022. Cases were mainly farmers, with a fluctuating upward trend of around 50% per year, with the highest percentage of 60.96% in 2020. The peak seasonal incidence of AHC was obvious from May to September from 2015 to 2019, but it was not obvious in 2020—2022. The cases were mainly distributed in Guangxi, Hainan and other provinces in the southwestern part of China. The high incidence counties were concentrated in Leye County of Guangxi, Maojian District of Hubei, Fuchuan Yao Autonomous County of Guangxi, Funing County of Yunnan, and Pulan County of Tibet every year. Conclusions:The overall epidemic rate of AHC in China showed a fluctuating downward trend from 2015 to 2022, with a pronounced decline observed between 2020 and 2022, potentially linked to non-pharmaceutical interventions during the COVID-19 pandemic. Increased attention needs to be given to farmers and people above 60 years of age to reduce the risk of morbidity. Moreover, prevention and control efforts should be strengthened in high-risk areas of southwestern China, and comprehensive measures should be implemented in counties with high incidence, including enhanced health education campaigns and improved allocation of sanitary facilities, to reduce the risk of AHC infection. This study is the first to highlight the potential impact of public health policies on AHC epidemiology, thereby offering a scientific foundation for population- and region-specific precision prevention strategies, particularly guiding the refinement of control measures in high-burden areas.

BACKGROUND:For thoracolumbar spine fractures with developmental stenosis of the vertebral arch,accurate nail placement is difficult using traditional fluoroscopy-assisted techniques.O-arm navigation assistance systems offer higher precision in general vertebral arch nail placement,but there is scarce literature on the application of O-arm navigation-assisted nail placement in thoracolumbar spine fractures with developmental stenosis of the vertebral arch both domestically and abroad. OBJECTIVE:To explore the accuracy of percutaneous vertebral arch nail placement assisted by O-arm navigation in patients with thoracolumbar spine fractures complicated by developmental stenosis of the vertebral arch. METHODS:A retrospective analysis was conducted on 53 patients who underwent percutaneous vertebral arch screw fixation surgery at Department of Orthopedics,General Hospital of Central Theater Command of PLA for thoracolumbar spine fractures complicated by developmental stenosis of the vertebral arch from January 2021 to March 2023.Totally 208 cases of vertebral arch developmental stenosis were found(cases with multiple vertebral arch developmental stenosis were counted separately).Based on the surgical approach,the patients were divided into two groups:O-arm navigation group(n=98)and C-arm fluoroscopy group(n=110).Postoperative imaging data were compared between the two groups,including anatomical perforation score,functional perforation score,actual vs.expected nail trajectory in the horizontal plane,and sagittal plane angle differences. RESULTS AND CONCLUSION:(1)There was no significant difference in the narrowest width of the pedicle isthmus(pow)between the two groups of patients(P>0.05).The proportions of different degrees of narrowing(mild:6 mm≤pow<7 mm,moderate:5 mm≤pow<6 mm,severe:pow<5 mm)were also not significantly different between the two groups(P>0.05).(2)The overall grade and scores of anatomical perforation and functional perforation were lower in the O-arm group compared to the C-arm group,and these differences were statistically significant(P<0.001).In terms of the angular deviation between the actual and planned screw trajectories,the O-arm group had smaller deviations,and these differences were statistically significant(P<0.05).(3)In the mild and moderate narrowing groups,the O-arm group showed significant advantages in anatomical perforation,functional perforation,and angular deviation between actual and planned screw trajectories,and these differences were statistically significant(P<0.001).(4)The O-arm group demonstrated better performance in anatomical perforation and functional perforation,especially in the T12-L2 segment,with more significant advantages.Additionally,the O-arm group had better angular deviations in actual and planned screw trajectories in all segments compared to the C-arm group.(5)Therefore,the use of O-arm navigation-assisted percutaneous screw placement for the treatment of thoracolumbar fractures with developmental pedicle isthmal narrowing provides higher accuracy and safer surgery.

ObjectiveTo explore the effects of Qingxin Jieyu granules on ventricular remodeling of mice after myocardial infarction， and their regulatory role in mitophagy. MethodsSixty male C57BL/6 mice were randomly assigned to six groups： sham-operated group， model group， Qingxin Jieyu granules low-， medium-， and high-dose groups （1.3， 2.6， 5.2 g·kg^-1）， and sacubitril valsartan sodium group （0.03 g·kg^-1）， with 10 mice per group. Except for the sham-operated group， all other groups utilized left anterior descending coronary artery ligation to build a myocardial infarction model. Ultrasound was used to measure left ventricular parameters， including end-diastolic and end-systolic diameters （LVIDd， LVIDs）， diastolic and systolic posterior wall thickness （LVPWd， LVPWs）， end-diastolic and end-systolic volumes （LV Vold， LV Vols）， left ventricular ejection fraction （LVEF）， and fractional shortening （LVFS）. Additionally， the heart mass index and heart weight/tibia length ratio of mice were calculated. Enzyme-linked immunosorbent assay （ELISA） was employed to quantify brain natriuretic peptide （BNP）， creatine kinase isoenzyme （CK-MB）， angiotensinⅡ （AngⅡ）， and lactate dehydrogenase （LDH） levels in the serum of mice. Histological analysis using hematoxylin-eosin （HE） and Masson staining was conducted to examine morphological changes in myocardial tissue. Immunohistochemistry assessed the expression of vascular growth factors， including basic fibroblast growth factor （bFGF） and vascular endothelial growth factor （VEGF）. Transmission electron microscopy was used to scrutinize mitochondrial morphology in the myocardial tissue of mice. Western blot was performed to analyze the expression of phosphorylated adenosine monophosphate activated protein kinase （p-AMPK） and phosphorylated mammalian target of rapamycin （p-mTOR） proteins in myocardial tissue from each experimental group. ResultsCompared to the sham-operated group， the model group mice exhibited significantly elevated levels of LV Vold， LV Vols， LVIDd， LVIDs， cardiac mass index， heart weight/tibia length ratio， BNP， LDH， and p-mTOR protein expression （P<0.05）， along with decreased levels of LVPWd， LVPWs， LVEF， LVFS， and p-AMPK protein expression （P<0.05）. The model group also displayed substantial inflammatory cell infiltration， collagen deposition in myocardial cells， reduced expression of bFGF and VEGF， mitochondrial swelling， and cristae fragmentation. Compared to the model group， the sacubitril/valsartan group and mid-dose Qingxin Jieyu granules group showed significant reductions in LVIDs， LV Vold， LV Vols， BNP， CK-MB， LDH， and p-mTOR protein expression （P<0.05）， coupled with increases in LVEF， LVFS， and p-AMPK expression （P<0.05）. Improvements were observed across all treatment groups， including reduced inflammatory cell infiltration and collagen deposition， increased bFGF and VEGF expression， alleviated mitochondrial swelling， and the presence of autophagosomes and lysosomes. ConclusionThe results show that Qingxin Jieyu granules can regulate mitochondrial autophagy in myocardial tissue and inhibit ventricular remodeling to improve cardiac performance， by up-regulating the p-AMPK expression in the myocardial tissue of mice with ventricular remodeling after myocardial infarction， and down-regulating the p-mTOR expression.

In endovascular treatment of peripheral arterial disease, paclitaxel-coated device (PCD) have been widely used to reduce vascular restenosis, yet their safety remains controversial. Some scholars have suggested that PCD might increase long-term mortality, sparking widespread concern and debate. In recent years, a number of studies have provided support for the safety of PCD, believing that PCD have advantages in terms of re-intervention, patency rate, and reduction of amputation risk, and do not increase the risk of death. There is no direct relationship between the paclitaxel dose and mortality. Overall, the safety controversy primarily stems from methodological limitations in early studies. The latest research has provided safety evidence for their clinical application. However, further investigations are required to define the boundary conditions for their long-term safety, elucidate variations in responses across different patient populations, and clarify paclitaxel′s mechanisms of action in vivo. Such efforts will facilitate optimal balancing of therapeutic efficacy and safety in clinical applications.

Objective To investigate the neurovascular coupling(NVC)status in the acute phase of patients with minor ischemic stroke(MIS)or transient ischemic attack(TIA)due to intracranial large artery moderate-to-severe stenosis or occlusion using multimodal MRI techniques and to explore its correlation with quality of life(QoL).Methods This prospective,consecutive study enrolled patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion form the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University,between June 2022 and October 2023.Recruit healthy subjects with matched age,sex,and handedness form the community during the same period.Patients were divided into left-sided involvement and right-sided involvement groups based on the affected side of the responsible vessel,while the healthy subjects were set as the healthy control group.Post-hoc power analysis was performed using G*Power 3.1 software.General characteristics(age,gender,body mass index,education level)were collected and compared across all three groups.Clinical data and QoL assessment were collected and compared between the two patient groups.Collected clinical data including type of cerebrovascular events(TIA,MIS),the National Institutes of Health stroke scale(NIHSS)score at admission,the responsible vessel(internal carotid artery,middle cerebral artery)and its side location,the degree of responsibility artery stenosis(moderate-severe stenosis[50%-99%stenosis rate],occlusion[100%stenosis rate]),the intracranial collateral circulation status(American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASITN/SIR]collateral circulation grading),cerebrovascular risk factors(hypertension,diabetes,hyperlipidemia,smoking history),and the laboratory test indicators at admission(glycated hemoglobin,triglycerides,total cholesterol,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,blood uric acid,blood homocysteine).QoL was assessed using the stroke impact scale(SIS),covering eight functional domains and a patient-reported overall recovery item.Multimodal MR data were acquired for all subjects.Whole-brain cerebral blood flow(CBF)images were generated using statistics parameter mapping 12(SPM 12)software,while regional homogeneity(ReHo)images were generated using DPABI software.The voxel-wise ratio of CBF to ReHo(CBF/ReHo)was calculated as the regional NVC parameter.Differences in regional NVC characteristics were compared between patient groups and the healthy control group.Correlations between NVC parameters and SIS scores within patient groups were explored.Results(1)A total of 38 patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion were included(26 males,12 females,aged 36-69 years,with mean age of[52±11]years),with 23 in the left-sided involvement group and 15 in the right-sided involvement group.Nineteen healthy subjects were included(10 males,9 females,aged 37-67 years,with mean age of[53±10]years).Post-hoc power analysis showed statistical power of 0.808 for comparing the left-sided involvement group with the healthy control group and 0.762 for comparing the right-sided involvement group with control group.(2)No statistically significant differences were found on gender,age,education level,or body mass index across the three groups(all P＞0.05).No statistically significant differences were observed on the type of cerebrovascular event,cerebrovascular risk factors,distribution of the responsible vessel,degree of stenosis in the responsible vessel,admission NIHSS score,or laboratory test results between the two patient groups(all P＞0.05).There were no statistically significant differences in the total SIS score and the scores of subscales between the two patient groups(all P＞0.05).(3)Compared with the healthy control group,the left-sided involvement group exhibited reduced CBF/ReHo values in the left superior and middle temporal gyri,supramarginal gyrus,middle and inferior frontal gyri,precentral gyrus,angular gyrus,postcentral gyrus,insula,and posterior cerebellar lobe(FDR-corrected,all P＜0.05).In the right-sided involvement group,reduced CBF/ReHo values were observed in the right supramarginal gyrus,right postcentral gyrus,inferior temporal gyrus,and insula(FDR-corrected,all P＜0.05).(4)Correlation analysis revealed that the SIS total score in the left-sided involvement group negatively correlated with CBF/ReHo values in the right inferior frontal gyrus(T=-5.91)and the right middle temporal gyrus(T=-6.65,FDR-corrected,both P＜0.05).The SIS subscale score for activities of daily living in the left-sided involvement group showed negative correlations with CBF/ReHo values in the right angular gyrus(T=-7.36),right medial superior frontal gyrus(T=-6.97),right orbitofrontal cortex(T=-8.99),and left thalamus(T=-7.51,FDR-corrected,all P＜0.05).No significant correlation was observed between the SIS total score and CBF/ReHo values in patients with right-sided involvement group.The SIS subscale for communication score in the right-sided involvement group correlated with CBF/ReHo in the left lingual gyrus(T=-12.15),left olfactory cortex(T=-7.68),and right anterior cingulate and paracingulate cortex(T=-9.46,FDR-corrected,all P＜0.05).Conclusions Patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion show abnormal NVC in the acute phase,especially those with left hemisphere involvement,who exhibit more extensive impairments.QoL in left-sided involvement patients is strongly linked to NVC in the right orbitofrontal cortex and right middle temporal gyrus.These findings require further validation in larger-scale studies.
