OBJECTIVE: To construct an integrated management model for early screening and diagnosis of PCa based on the Innovative Care for Chronic Conditions Framework (ICCC) and the 1+1 contract-based tiered diagnosis and treatment system (TDTS) in China. METHODS: Based on the 1+1 contract-based TDTS platform, we conducted PCa screening for the male residents aged 60 years and above during health check-ups in Pujin Community Health Center from January 1, 2023 to December 31, 2023. For those with abnormal total prostate-specific antigen (tPSA) ≥ 4 μg/L, we promptly referred them to higher-level hospitals for further diagnosis and treatment via the two-way referral green channel platform and information sharing service using the 1+1 contract model. We further analyzed the relevant data on screening and diagnosis. RESULTS: A total of 4 080 males aged 71.39±5.059 years received PCa screening from January to December 2023. PSA screening was performed in 43.96% of the male residents, revealing 654 cases of PSA abnormality, with a PSA positivity rate of 16.03%, which was higher than that found in the previous large-scale PCa screenings in other regions of China. Among the males with PSA abnormality, 292 (44.65%) expressed their willingness for medical referral, while the others did not seek further medical attention for reasons of being asymptomatic, low awareness of the disease, no accompany for medical visits, and concerns about further costs of diagnosis and treatment. Prostate biopsy was recommended to 154 cases after further examinations, which was accepted by 92 (59.74%). Fifty-eight cases were diagnosed with Pa, and thedetection rate reached 63.04%. CONCLUSION The integrated management model for PSA examination-based early screening and diagnosis of PCa using the 1+1 contract-based TDTS platform is plays a significant role in enhancing people's awareness and knowledge of PCa and improving the early detection rate of the malignancy.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

Uric acid (UA) is the final product of purine metabolism in human body,and its metabolic disorder will induce hyperuricemia (HUA).The occurrence and development of HUA are associated with a variety of pathological mechanisms such as oxidative stress injury,activation of inflammatory cytokines,and activation of renin-angiotensin-aldosterone system.These mechanisms directly or indirectly affect the bioavailability of endogenous nitric oxide (NO).The decrease in NO bioavailability is common in the diseases with high concentration of UA as an independent risk factor.In this review,we summarize the mechanisms by which high concentrations of UA affect the endogenous NO bioavailability,with a focus on the mechanisms of high-concentration UA in decreasing the synthesis and/or increasing the consumption of NO.This review aims to provide references for alleviating the multisystem symptoms and improving the prognosis of HUA,and lay a theoretical foundation for in-depth study of the correlations between HUA and other metabolic diseases.

Objectives: To establish a newly-designed scoring system for breast imaging-reporting and data system (BI-RADS) 4 and 5 breast lesions only visible on MRI, and to examine their clinical pathway of biopsy. Methods: The BI-RADS 4 and 5 breast lesions only visible on MRI but not suspected on mammograms or ultrasound between June 2007 and December 2021 at Beijing Hospital were evaluated retrospectively. A total of 209 lesions from 184 patients were finally included. All patients were female, aged (50±11) years (range: 27 to 76 years). All lesions were confirmed by pathology and divided into malignancy and non-malignancy. The lesions were divided into mass and non-mass type using BI-RADS. The receiver operator characteristic (ROC) curve was used to evaluate the diagnostic performance of the new scoring system. Four types of pathology-obtaining pathway were used: biopsy guided by second-look ultrasound, local excision guided by lesion position information on MRI, intraductal lesion excision guided by methylene blue stain and mastectomy. The data between mass and non-mass lesions were compared by Mann-Whitney U test, χ² test or Fisher exact test,respectively. Results: There were 124 malignant and 85 non-malignant lesions, while 100 mass and 109 non-mass lessions. The sizes between mass and non-mass lesions showed significant difference(M(IQR)) (7.0 (3.0) mm vs. 25.0 (25.0) mm, U=568.000, P<0.01) and their BI-RADS diagnostic accuracy had no significant difference (53.0% (53/100) vs. 65.1% (71/109), χ²=3.184, P=0.074). The areas under ROC curve of the new scoring system for evaluating mass and non-mass were 0.841 and 0.802, respectively. When taking Score 3 as threshold, it can potentially avoid 14.0% (14/100) and 4.6% (5/109) of biopsies in mass and non-mass, respectively. As to pathway of obtaining pathology, second-look ultrasound succeeded more easily in mass than non-mass (41.0% (41/100) vs.26.6% (29/109), χ²=4.851, P=0.028). More MRI-guided local excisions were performed in non-mass than mass (52.3% (57/109) vs. 34.0% (34/100), χ²=7.100, P=0.008). Conclusions: For suspicious breast lesions detected by MRI but not suspected on X-ray or ultrasound, the new scoring system can further increase diagnostic accuracy. The second-look ultrasound plays an important role for obtaining pathology, especially for mass-type lesion.

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.

Objective To explore the effect of imiquimod (IMQ) on the proliferation of glioma U87 cell line U87. Methods U87 cells were divided into control group, 1 mmol/L I mmol/L MQ group, 5 mmol/L IMQ group, 1 mmol/L IMQ+ STAT3 inhibitor(STAT3-IN) group and 5 mmol/L IMQ + STAT3-IN group. To detect the number of 5-ethynyl-2 ' - deoxyuridine(EdU) -labeled cells or proliferation absorbance(A) values in each group by EdU and MTT assays. Interleukin (I L) - 6 mRNA, tumor necrosis factor (TNF) -a mRNA and protein content in U87 cells of each group were detected by Real-time PCR or ELISA. Western blotting was used to detect the protein expression of STAT3, phosphorylated STAT3 (p - S T A T 3), nuclear factor (N F) -KB and phosphorylated NF-KB (p-NF-KB) in U87 cells of each group. Results Compared with the control group, the number of EdU-labeled cells and absorbance values of U87 cells were successively decreased in 1 mmol/L IMQ group and 5 mmol/L IMQ group, showing a dose-dependent manner (P < 0 . 0 1, n— 1 0) . However, the number of EdU-labeled cells and the A values in IMQ + STAT3-IN group and 5 mmol/L IMQ + STAT3-IN group were significantly reduced. Compared with the control group, the protein expression of STAT3, p-STAT3, N F - K B, P ~ N F - K B, IL-6 and TNF-a were continuing low level in U87 cells of 1 mmol/L IMQ group and 5 mmol/L IMQ group (P < 0 . 0 1, * = 1 0) . As well as in 1 mmol/L IMQ + STAT3-INgroup and 5 mmol/L IMQ + STAT3-IN group, the proteins of above were low expressed (P < 0 . 01, n— 10) . Conclusion Imiquimod decreased the contents of IL-6 and TNF-a by down-regulating S T A T 3 / N F - K B pathway, and thus inhibited the proliferation of U87 cells.

Objective To evaluate the risk of hearing loss of assembly workers in an automobile manufacturing factory. Methods An 8-hour equivalent sound level monitoring was carried out for assembly posts in an automobile factory. The risk of noise-induced hearing loss of assembly workers was measured using the method specified in ISO 1999:2013(E). The risk of noise-induced hearing loss was assessed in a graded manner according to the Guidelines for the Management of Occupational Disease Hazards from Noise. The results were statistically analyzed using Pearson correlation analysis. Results The average 8-hour equivalent sound level of the assembly work post in this automobile manufacturing factory was 89.5 dB (A). At 4000 Hz, the hearing loss N₅₀ (dB) of assembly workers reached the maximum. The longer the exposure time, the higher the risk of high-frequency standard hearing threshold shift. The risk of high-frequency standard hearing threshold shift was at a relatively high level at 30 years of work, while the risk of noise deafness reached a higher level after 40 years of work. Conclusion The 8-hour equivalent sound level (L_EX,8h) of assembly workers in the automobile factory exceeds the occupational exposure limit. With the increase of exposure years, the risk of high-frequency standard hearing threshold shift and noise deafness increases.

Objective To systematically analyze the framework and core content of physical activity inclusive school health policies. Methods This study conducted systematic content analysis of key messages of WHO key documents related to physical activity and school health services, and constructed policy and research framework. WHO's key policy documents in the field of school health included: Making Every School a Health-Promoting School Implementation Guidelines, WHO Guidelines on School Health Services, and the Global Criteria and Indicators for Making Every School a Health-Promoting School, and the key documents in the field of physical activity mainly include Global Action Plan for Physical Activity Promotion 2018-2030: Strengthening Physical Activity for a Healthy World, and WHO Guidelines on Physical Activity and Sedentary Behavior (Children and adolescents). Results Physical activity, as a health strategy and development strategy, is one of the most important tools for achieving health-promoting schools. In the area of health and education, the key to building health-promoting schools is to focus on child functioning and development, with the goal of promoting healthy inclusion and equity in schools. In the school setting, physical activity for children and adolescents is integrated into the school health service continuum with a focus on health promotion. At the macro level, the state and relevant authorities should establish a strategic structure and strategic planning for the integration of physical activity into the school health service system. At the meso level, educational institutions should develop and improve school health service policies and programs, and improve school health service tools based on the requirements of WHO school health service guidelines. Child health services are achieved through the provision of high-quality physical education programs and after-school physical activities. At the micro level, guided by global standards for building health-promoting schools, physical activity is promoted in the form of lessons and activities for healthy child development. Integrating physical activity into the school health service system can be done in six areas: school health leadership and governance, school infrastructure funding, school health service delivery that supports physical activity, human resources for school health, school health-related medicine and technology, and school health information system. We need to implement health-promoting school policies, strengthen multi-level school leadership and governance, raise the necessary funds to develop human resources adapted to the construction of health-promoting schools and build programs to support physical activity. Conclusion School health service is an important area for promoting children's health and achieving the UN 2030 Sustainable Development Goals, and physical activity is an important strategy of school health services. Policy documents issued by WHO construct the integration of physical activity into the policy framework of the school health service system, of which the core component is to integrate physical activity into the health-promoting school with educational and physical activity approaches. According to the WHO six building blocks of health service system, the integration of physical activity into the school health requires strengthening school health leadership and governance, improving school infrastructure financing, developing school health human resources, developing school-based health-related medical technologies, and establishing a health information system for sharing student health data.
