Objective To evaluate the predictive value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) 3.0T enhanced magnetic resonance imaging (MRI) for microvascular invasion (MVI) in young and middle-aged patients with small hepatocellular carcinoma (SHCC). Methods Seventy young and middle-aged patients with SHCC were divided into MVI (n=21) and non-MVI (n=49) groups. All patients underwent preoperative univariate analysis of qualitative and quantitative parameters of Gd-EOB-DTPA MRI enhancement, and multivariate logistic regression was performed using the parameters that differed between groups as independent variables. Receiver operating characteristic and Kaplan–Meier survival curves were drawn to determine the predictive parameters and predict postoperative recurrence and metastasis. Results Significant differences in the qualitative parameters of tumor shape, tumor margin, pseudocapsule completeness, peritumoral hypointensity in the hepatobiliary phase, and peritumoral enhancement in the artery phase were found between the MVI and non-MVI groups (P<0.05); with regard to the quantitative parameters, the apparent diffusion coefficient (ADC) values of tumors between two groups were statistically significant (P<0.05). Multivariate logistic regression analysis showed that small ADC, peritumoral hypointensity in the hepatobiliary phase, and peritumoral enhancement were independent risk factors of MVI in young and middle-aged patients with SHCC (P<0.05). Survival analysis revealed that the recurrence rate of the MVI group was higher than that of the non-MVI group in the first two years. Conclusion Gd-EOB-DTPA-enhanced MRI is valuable in predicting the presence of MVI and postoperative recurrence and metastasis in young and middle-aged patients with SHCC.

The paper introduces Professor ZHUANG Lixing's academic thought on Daoqi Tongjing (directing qi to preserve essence) needling technique and the clinical experience. Based on Huangdi Neijing (the Yellow Emperor's Inner Classic), Dongyuan needling technique and Professor JIN Rui 's Daoqi Tongjing needling method, and by inheriting the valuable experience from the ancient masters and associating with his own clinical practices, Professor ZHUANG Lixing fully displayes the characteristics of principles, methods, formulas, acupoints and techniques of acupuncture in diagnosis and treatment of diseases. He integrates the thought of regulating the mind with Daoqi Tongjing needling. This needling method focuses on directing qi through mind regulation and needle manipulation, in which, the operation steps are refined. Besides, this needling method involves both the reinforcing and reducing techniques. The satisfactory effect of this needling has been obtained in clinical treatment for many disorders such as qi reversion and disharmony of yin and yang.

OBJECTIVE: To investigate the clinical value of MRI modified water-lipid separation technique (mDIXON-Quant) in terms of T2* values and fat fraction (FF) values for evaluating the degree of cervical intervertebral disc degeneration. METHODS: A total of 118 patients who underwent routine MRI of the cervical vertebra and the mDIXON-Quant examination in Fuyang People's Hospital from March 2019 to January 2024 were collected. The T2* values of C2/3 to C6/7 intervertebral discs and FF values of the upper and lower vertebral bodies were measured. Cervical intervertebral disc degeneration was graded according to the Pfirrmann criteria. The T2* values and FF values of different patients were compared with the Pfirrmann grades, and the correlation between T2* values, FF values, and Pfirrmann grades was analyzed by Spearman correlation. RESULTS: The T2* values of cervical intervertebral discs in grades I, II, III, IV, and V all showed a decreasing trend ( P＜0.05). The decreasing order of FF values in the upper cervical vertebra was IV, V, III, II, and I ( F=93.28, P＜0.05), and the decreasing order of FF values in the lower cervical vertebra was IV, III, V, II, and I ( F=112.037, P＜0.05). Spearman correlation analysis showed that the T2* values of cervical intervertebral discs were negatively correlated with the Pfirrmann grades ( P＜0.05), and the FF values of the upper and lower vertebrae were positively correlated with the Pfirrmann grades ( P＜0.05). CONCLUSION The mDIXON-Quant technique can be used to quantify the T2* values and FF values of cervical intervertebral disc degeneration and plays an important role in accurate clinical diagnosis and evaluation of treatment effects.

The underlying cause of low response rates to existing immunotherapies is that tumor cells dominate tumor immune escape through surface antigen deficiency and inducing tumor immunosuppressive microenvironment (TIME). Here, we proposed an in situ tumor cell engineering strategy to disrupt tumor immune escape at the root by restoring tumor cell MHC-I/tumor-specific antigen complex (MHC-I/TSA) expression to promote T-cell recognition and by silencing tumor cell CD55 to increase the ICOSL⁺ B-cell proportion and reverse the TIME. A doxorubicin (DOX) and dual-gene plasmid (MAC pDNA, encoding both MHC-I/ASMTNMELM and CD55-shRNA) coloaded drug delivery system (LCPN@ACD) with tumor targeting and charge/size dual-conversion properties was prepared. LCPN@ACD-induced ICD promoted DC maturation and enhanced T-cell activation and infiltration. LCPN@ACD enabled effective expression of MHC-I/TSA on tumor cells, increasing the ability of tumor cell recognition and killing. LCPN@ACD downregulated tumor cell CD55 expression, increased the proportion of ICOSL⁺ B cells and CTLs, and reversed the TIME, thus greatly improving the efficacy of αPD-1 and CAR-T therapies. The application of this in situ tumor cell engineering strategy eliminated the source of tumor immune escape, providing new ideas for solving the challenges of clinical immunotherapy.

Since 1986, the WHO has held ten global health promotion conferences covering various health promotion issues and sustainable development worldwide. These sessions have formed a series of consensus and actions that guide promoting health globally. This study analyzed the declarations, reports, and news materials from the ten conferences that studied health promotion action areas, focal topics, actor networks, partnership relationships, and other significant outcomes. It also explored how these conferences contributed to the construction and advancement of global health promotion consensus and actions. The first Global Conference on Health Promotion identified the concept of health promotion and five key action areas, laying the foundation for subsequent conferences and health promotion actions. Over the years, the ten conferences continuously expanded the essence of health promotion, developed partnership relationships, formulated public health promotion policies, and called for health promotion actions. This process culminated in the formation of global consensus and collective actions. The latter conferences have gained significant attention and influence. The conferences offer valuable insights for future global health promotion endeavors and provide global perspectives and pathways for the development of Healthy China.

Parkinson’s disease (PD) is a neurodegenerative disease characterized by various motor and non-motor symptoms. The complexity of its symptoms suggests that PD is a heterogeneous neurological disorder. Its pathological changes are not limited to the substantia nigra-striatal system, but gradually extending to other regions including the cerebellum. The cerebellum is connected to a wide range of central nervous system regions that form essential neural circuits affected by PD. In addition, altered dopaminergic activity and α-synuclein pathology are found in the cerebellum, further suggesting its role in the PD progression. Furthermore, an increasing evidence obtained from imaging studies has demonstrated that cerebellar structure, functional connectivity, and neural metabolism are altered in PD when compared to healthy controls, as well as among different PD subtypes. This review provides a comprehensive summary of the cerebellar pathophysiology and results from neuroimaging studies related to both motor and non-motor symptoms of PD, highlighting the potential significance of cerebellar assessment in PD diagnosis, differential diagnosis, and disease monitoring.

Pathological,electrophysiological,and neuroimaging changes in the cerebellum can occur in neurodegenerative diseases such as Alzheimer disease,Parkinson disease,and amyotrophic lateral sclerosis.The activation and neurodegeneration of neurons in specific cerebellar regions may contribute to the clinical symptoms and pathological processes of these neurodegenerative diseases.This article reviews the clinical assessment methods and neuroimaging studies related to cerebellar symptoms in neurodegenerative diseases.The findings suggest that structural and functional abnormalities of the cerebellum are associated with symptoms such as motor,cognitive,and emotional dysfunction in these diseases.Developing a multidimensional,systematic clinical and imaging evaluation approach centered on the cerebellum will help deepen our understanding of the cerebellum's role in the pathogenesis of neurodegenerative diseases.It will also provide new directions for the early identification of symptoms,differential diagnosis,and the formulation of precise treatment plans.

Objective:This study analyzed how the 10 Global Conferences on Health Promotion have played a significant role in shaping and promoting a worldwide consensus and actions on health promotion,effectively addressing diverse health challenges that evolved over different periods. Methods:The textual analysis method was used in this study and text encoding was conducted to systematically examine the declarations and reports presented by the 10 Global Conferences on Health Promotion held during 1986-2021.We summarized the themes and key achievements,and key vocabulary in the conference declarations was extracted and analyzed to construct the global health promotion consensus and actions. Results:The fundamental principles of the conferences are to foster consensus and initiate actions in the realm of health promotion on a global scale.The primary purpose and goal are to promote health from regional to global.Significantly,our findings highlight a transition in the primary actors driving health promotion.It underscores a shift in health promotion from being driven primarily by organizations like the World Health Organization,governments,and international bodies,to a more inclusive approach involving non-governmental organizations and the general public.This development implies that health promotion has evolved into a collective global en-deavor,demanding the proactive involvement of various stakeholders,and forging new alliances in public health.Meanwhile,the coronavirus disease 2019(COVID-19)pandemic has further shaped the landscape of health pro-motion,underscoring the need for intensified focus on areas including disease prevention,health education,and the integration of digital health technologies,and emphasizing the importance of a multidimensional,responsive approach in public health initiatives. Conclusions:Sustained collaboration and innovative strategies are pivotal to advancing health promotion globally.Countries,together with public and private entities,should intensify cooperation.Multisectoral collaboration among partners such as healthcare,education,social security,and the industry is vital for health promotion and achieving global health goals.

Objective:To investigate the survival rate and clinical failure reasons of onlay and occlusal veneer restorations retrospectively,and to put forward valuable suggestions for the selection of clinical in-dications.Methods:A total of 102 patients and 124 teeth treated by one of the authors from 2016 to 2019 were subjected to CAD/CAM lithium silicate reinforced glass-ceramic onlay or veneer restorations of premolars and molars,including 43 teeth with pulp vitality,81 endodontic treated teeth,and occlusal thickness of restoration was 1.5 mm.After four years of restoration,retrospective surveys were conducted to record the survival rate of restorations,the causes of restoration failure,and patient satisfaction rates,and the survival rate of restorations between vital teeth and endodontic treated teeth and among restored teeth was statistically analyzed by Chi-square test.Results:The survival rates of restorations on vital teeth and endodontic treated teeth were 95.5％and 90.0％,respectively,the average survival rate was 90.2％.The survival rates of vital teeth were higher than those of endodontic treated teeth without statis-tical difference.There was also no statistically significant difference among the tooth locations.The cau-ses of failure included the cracking of the restoration,the loss of the restoration,the fracture of the abut-ment teeth,secondary caries below the adjacent contact point,and food impaction caused by the loose-ning of the adjacent contact point.The overall patient satisfaction rate was 91.5％.Conclusion:The 4-year survival rate of glass-ceramic onlays and occlusal veneers is lower than that of the full crown restora-tion,and there are more complications than that of the single-crown restorations.The design of the resto-ration should be carefully selected based on the vitality of the abutment tooth and the remaining amount of tooth tissue.When there is too little tooth structure left,a post and crown should be selected for restora-tion.Adequate strength and thickness of the restoration should be ensured to prevent food impaction.Due to the small amount of abutment tooth preparation,it has the advantages of less stimulation of the pulp and periodontal tissue,and can be recommended as a trial restoration.

Objective:To analyze the relationship between dietary composition of residents in endemic fluorosis areas and skeletal fluorosis.Methods:A case-control study was used to analyze the difference of dietary composition between patients with skeletal fluorosis (case group) and residents without skeletal fluorosis (control group). In August 2019, taking the drinking water-borne endemic fluorosis area in Wenshui County, Lvliang City, Shanxi Province as the survey site, a cluster sampling method was adopted to select local residents aged over 18 years old, and a questionnaire survey was conducted by face-to-face interview. The survey contents included gender, age and consumption frequency of various foods. Binary logistic regression was used to analyze the relationship between food consumption frequency and skeletal fluorosis. The diagnosis of skeletal fluorosis was made by using portable digital radiography (DR) to take X-ray films of forearm and lower leg, combining with clinical signs, and according to the Diagnostic Standard for Endemic Skeletal Fluorosis (WS/T 192-2008) to determine.Results:A total of 1 061 subjects were included in this study, including 376 in the case group and 685 in the control group. The age composition of patients in the case group (≤60, > 60 years old: 162, 214 cases) was significantly different from that in the control group (≤60, > 60 years old: 423, 261 cases, χ 2 = 34.52, P < 0.001). There was no statistically significant difference in gender ratio (χ 2 = 1.37, P = 0.251). The proportion of patients in the case group who ate meat and eggs > 1 time/week was lower than that in the control group (χ 2 = 8.06, 5.46, P < 0.05), the proportion of patients who ate milk > 1 time/week was higher than that in the control group (χ 2 = 4.01, P = 0.046), and the proportion of patients who ate seafood ≥1 time/week was lower than that in the control group (χ 2 = 4.16, P = 0.046). The results of binary logistic regression analysis showed that after adjusting for age, sex, and urinary fluoride, the frequency of eating meat, eggs or milk > 1 time/week and the frequency of eating seafood ≥1 time/week were not related to the risk of skeletal fluorosis ( P > 0.05); however, in the group ≤60 years old, the frequency of eating eggs > 1 time/week was associated with the risk of skeletal fluorosis [odds ratio ( OR) = 0.59, 95% confidence interval ( CI): 0.39, 0.88]. Conclusions:The consumption frequency of meat, milk, eggs and seafood is significantly different between the skeletal fluorosis patients and the control people. In the population ≤60 years old, consumption frequency of eggs > 1 time/week may reduce the risk of skeletal fluorosis.
