ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4+ T lymphocytes, CD8+ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4+ T lymphocytes. Additionally, spleen CD4+ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4+ and CD8+ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4+ and CD8+ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4+ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4+ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

BACKGROUND:
As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034.
METHODS:
The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC).
RESULTS:
Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively.
CONCLUSIONS
The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Lung transplantation is the optimal treatment for end-stage lung diseases and can significantly improve prognosis of the patients. However, postoperative complications such as infection, rejection, ischemia-reperfusion injury, and other challenges (like shortage of donor lungs) , limit the practical application of lung transplantation in clinical practice. Chinese research teams have been making continuous efforts and have achieved breakthroughs in basic research on lung transplantation by integrating emerging technologies and cutting-edge achievements from interdisciplinary fields, which has strongly propelled the development of this field. This article will comprehensively review the academic progress made by Chinese research teams in the field of lung transplantation in 2024, with a focus on the achievements of Chinese teams in basic research on lung transplantation. It aims to provide innovative ideas and strategies for key issues in the basic field of lung transplantation and to help China's lung transplantation cause reach a higher level.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.
5.Changes in life expectancy of residents in Jiashan County from 2013 to 2023
Journal of Preventive Medicine 2025;37(6):598-602
Objective:
To understand the trends in life expectancy among residents of Jiashan County, Zhejiang Province from 2013 to 2023, so as to provide the basis for determining the priorities of public health prevention and control.
Methods:
The crude mortality was calculated based on the surveillance on causes of death in Jiashan County, and standardized by the data from the Sixth Chinese National Population Census in 2010. The life expectancy among residents were calculated using life table method. The trend of mortality and life expectancy were analyzed by average annual percent change (AAPC). The increments in life expectancy attributable to different age groups and causes of death were dissected using the Arriaga decomposition method, and their respective contribution rates were calculated.
Results:
From 2013 to 2023, there were 34 117 deaths in Jiashan County. The average standardized mortality rate was 352.69/105, showing a downward trend (AAPC=-1.965%, P<0.05). The trend for men was consistent with that of the entire population (AAPC=-1.955%, P<0.05), while no significant trend was observed for women (AAPC=-1.901%, P>0.05). The life expectancy of the entire population increased from 81.80 years in 2013 to 83.42 years in 2023, showing an upward trend (AAPC=0.206%, P<0.05). The increase in life expectancy was 2.61 years from 2013 to 2021 and -0.99 years from 2021 to 2023. The overall increase in life expectancy from 2013 to 2023 was mainly influenced by the 35-<65 and ≥65 age groups, with increases of 0.81 years and 0.65 years, contributing 50.27% and 40.38%, respectively. From 2013 to 2021, the increase was mainly influenced by the ≥65 age group, with an increase of 2.12 years, contributing 81.12%. From 2021 to 2023, the decrease was mainly influenced by the ≥65 age group, with a decrease of 1.49 years, contributing 150.28%. The overall increase in life expectancy from 2013 to 2023 was mainly influenced by tumors and respiratory diseases, with increases of 1.03 years and 0.27 years, contributing 63.46% and 16.40%, respectively. From 2013 to 2021, the increase was mainly influenced by respiratory diseases and tumors, with increases of 1.47 years and 0.90 years, contributing 56.36% and 34.63%, respectively. From 2021 to 2023, the decrease was mainly influenced by respiratory diseases and circulatory diseases, with decreases of 1.10 years and 0.38 years, contributing 111.40% and 38.81%, respectively.
Conclusion
From 2013 to 2023, the increase in life expectancy among residents of Jiashan County was mainly influenced by changes in mortality from tumors and respiratory diseases among the middle-aged and elderly population aged 35 and above.

AIM:To evaluate the effectiveness of EYESI binocular indirect ophthalmoscope simulation system as a training platform for fundus examination skills of general practitioner.METHODS:Prospective randomized study. A total of 40 general practitioners who received clinical ophthalmology training at Shenzhen Eye Hospital from January 2021 to December 2024 were selected and randomly divided into two groups by random number table method, with 20 cases in the study group and 20 cases in the control group. The study group was trained by EYESI binocular indirect ophthalmoscope simulation system and the control group was trained by conventional teaching. Training effects of the two groups were analyzed.RESULTS: The general information of the two groups was comparable. Through training with the EYESI binocular indirect ophthalmoscope simulator, the study group showed significant improvements in total examination and drawing scores compared to pre-training results(all P<0.001). Additionally, examination duration, retinal light exposure time, and drawing time were all significantly shorter than those before training(all P<0.001).The study group achieved significantly higher total examination and drawing scores than the control group during the EYESI binocular indirect ophthalmoscope simulator assessment(all P<0.001). Furthermore, examination duration, retinal light exposure time, and drawing time were all significantly shorter in the study group compared to the control group(all P<0.001). Moreover, ratings for the novelty of the training method and overall satisfaction with the training were significantly higher in the study group than in the control group(all P<0.001); while the perceived psychological stress during training was significantly lower in the study group(P<0.001).CONCLUSION:The EYESI binocular indirect ophthalmoscope simulaton system effectively enhances both the proficiency in fundus examination skills and overall training satisfaction among general practitioners.

OBJECTIVES:
To evaluate the causal association between circulating levels of zinc, magnesium, and other minerals and autism spectrum disorder (ASD).
METHODS:
A two-sample Mendelian randomization (MR) analysis was performed using summary statistics from large-scale genome-wide association studies of European populations, including 18 382 ASD cases and 27 969 controls. Genetic data for iron, calcium, and magnesium were obtained from the UK Biobank, and data for zinc and selenium were sourced from an Australian-British cohort. A total of 351 genetic instrumental variables were selected. Causal inference was performed using inverse-variance weighting as the primary analysis method. Sensitivity analyses were performed by Cochran's Q test and MR-PRESSO global test to assess the robustness of the findings.
RESULTS:
No statistically significant causal effect was observed for circulating zinc, magnesium, calcium, selenium, or iron levels on ASD risk (all P>0.05). The odds ratios and 95% confidence intervals from the inverse-variance weighting analysis were 0.934 (0.869-1.003) for zinc, 1.315 (0.971-1.850) for magnesium, 1.055 (0.960-1.159) for calcium, 1.015 (0.953-1.080) for selenium, and 0.946 (0.687-1.303) for iron. Sensitivity analysis revealed significant heterogeneity in the causal association between circulating calcium and ASD (P=0.006), while the effect estimate remained stable after MR-PRESSO correction (P=0.487). The causal effect estimates for the remaining minerals demonstrated good robustness.
CONCLUSIONS
This study did not find significant evidence supporting a causal association between circulating zinc, magnesium, calcium, selenium, or iron levels and ASD risk, providing important clues for the etiology of ASD and precision nutritional interventions.

Objective:To explore the relationship between CT renal imaging parameters measured by 3D-slicer software and glomerular filtration rate (GFR) measured by 99mTc-DTPA renal dynamic imaging. Methods:A retrospective analysis was conducted on the clinical data of 177 patients (65 renal transplant donors, 60 patients with obstructive nephropathy, and 52 patients with renal tumors) admitted to Beijing Friendship Hospital, Capital Medical University from January 2015 to August 2021. GFR was measured for all patients. After three-dimensional imaging reconstruction of the urinary system enhanced CT using the 3D-slicer software platform, renal cortical volume, parenchymal volume, and average CT values were measured. A total of 189 kidneys (65 healthy kidneys, 72 hydronephrotic kidneys, and 52 tumor kidneys) were analyzed for the above parameters. The statistical analysis methods used independent sample t-test, one-way analysis of variance (ANOVA), Pearson correlation analysis, and receiver operating characteristics (ROC) curve analysis. Results:Compared with healthy kidneys, renal cortex volume and parenchyma volume in hydronephrotic and tumor kidneys were significantly reduced ( P<0.001), and GFR was significantly lower ( P<0.001). Among the 189 renal parameters, except for renal medulla volume ( r=0.146, P=0.531), renal cortex volume ( r=0.784, P<0.001) and renal parenchyma volume ( r=0.698, P<0.001) were significantly correlated with GFR. The results of one-way ANOVA showed significant differences between the groups in terms of renal cortex volume ( F=142.62, P<0.001), renal parenchyma volume ( F=92.92, P<0.001), average CT value of the renal cortex ( F=12.68, P<0.001), average CT value of the renal parenchyma ( F=19.68, P<0.001), and renal medulla volume ( F=3.26, P=0.041). Significant differences were observed between the subgroups for both renal cortex and parenchyma volumes ( P<0.001). Compared with other parameters, renal cortex volume showed higher diagnostic performance in distinguishing different levels of renal function. When the renal cortex volume was set to 77.91 mL and 45.46 mL, respectively, the diagnostic performance for distinguishing normal renal function from mild renal impairment ( AUC=0.830, 95% CI: 0.761-0.889, P<0.001) and mild renal impairment from severe renal impairment ( AUC=0.894, 95% CI: 0.787-0.952, P<0.001) showed high sensitivity and specificity. Conclusions:The measurement of renal imaging parameters using 3D-slicer software has clinical value in evaluating renal function in patients. Renal cortex volume demonstrates good diagnostic performance in distinguishing different levels of renal function, and is worthy of clinical promotion and application.

Objective:
To investigate the protective effects and mechanisms of acellular nerve allografts (ANA) on motor neurons in the spinal cord anterior horn of sciatic nerve injury ( SNI) rats .
Methods:
SPF grade male SD rats were randomly divided into normal , model , ANA-bridged (bridge group) , and autologous nerve transplantation groups (autograft group) , with 6 rats in each group . The SNI rat model was established using the right sciatic nerve clamp method for 10 mm . In the bridge group , the ANA was bridged to the two severed ends of the injured sciatic nerve , and in the autograft group , the autologous nerves were flipped head to tail and then bridged to the two se- vered ends . A spectrophotometer was applied to determine the DNA content in normal nerves and ANA . The foot- print test was used to determine the sciatic nerve function index (SFI) of the rats in each group , the wet weight ra- tio of the anterior tibialis muscle was calculated . The morphology and structure of the anterior horn motor neurons of the spinal cord of each group were observed by HE staining. The immunofluorescence and Western blot were used to detect Apaf-1 , Caspase-3 , Bcl-2 , Bax , and Cyt-C proteins expression in the L4-6 segment of the spinal cord .
Results:
The DNA content in the ANA prepared in this study was significantly lower than that in normal nerves (P < 0. 05) . Compared with the normal group , the SFI and wet weight ratio of the anterior tibialis muscle were re- duced in the model group (P < 0. 001) ; compared with the model group , both SFI and wet weight ratio of the ante- rior tibialis muscle significantly increased in the bridge group and the autografts group ( P < 0. 05 , P < 0. 001) , and the SFI and wet weight ratio of the anterior tibialis muscle in the autograft group were higher than those in the bridge group (P < 0. 001 , P < 0. 01) . The results of HE staining showed that the motor neurons in the anterior horn of the spinal cord of the normal group were structurally intact and had clear cytosolic boundaries; the neurons in the model group were lysed and necrotic , with blurred cytosolic boundaries; the neurons in the bridge group were less lysed and necrotic , but the nuclear translocation phenomenon could still be seen; the neurons in the autograft group were morphologically and structurally intact with clear cytosolic boundaries . Compared with the normal group , the expression of Apaf-1 , Caspase-3 , Bax and Cyt-C proteins significantly increased in the model group (P < 0. 001 , P < 0. 01 , P < 0. 01 , P < 0. 05) . Compared with the model group , the expression of Apaf-1 , Caspase- 3 , Bax , and Cyt-C proteins significantly decreased (P < 0. 001 , P < 0. 05 , P < 0. 05 , P < 0. 05) ; but the expres- sion of Bcl-2 protein significantly increased in the bridge group and the autograft group (P < 0. 05) . The expression of Apaf-1 , Caspase-3 , Bax and Cyt-C proteins in the autografts group was lower than that in the bridge group (P < 0. 001 , P < 0. 05 , P < 0. 05 , P < 0. 05) .
Conclusion
ANA can exert a protective effect on motor neurons in the anterior horn of the spinal cord of SNI rats by improving the morphology and structure of neurons , increasing the ex- pression of Bcl-2 protein , but decreasing the expression of Cyt-C , Bax , Caspase-3 , and Apaf-1 proteins in the spi- nal cord . The mechanism of ANA may be related to the Bcl-2/Cyt-C/Apaf-1-mediated mitochondrial apoptosis sig- naling pathway .
