ObjectiveTo investigate the level of hepatitis B surface antibody (anti-HBs) among preschool children (aged 3‒6 years) and primary and secondary school students in Tonglu County, Zhejiang Province, to evaluate the effectiveness of hepatitis B vaccination, and to provide a basis for hepatitis B prevention and control in the region. MethodsAs part of the 2023 Tonglu County Urban and Rural Residents Health Examination Program, blood samples were collected during health check-ups. Fingertip blood samples were obtained from preschool children, while venous blood samples were collected from primary and secondary school children. The anti-HBs levels in blood (positive + / negative -) were qualitatively tested using hepatitis B surface antibody test kits (latex method). The differences in anti-HBs positivity rates among different age groups were analyzed. ResultsBetween April 1, 2023 and June 30, 2023, a total of 52 919 individuals were surveyed, including 11 973 preschool children and 40 946 primary and secondary school students. The overall anti-HBs positivity rate was 39.74%, with the highest positivity rate observed among preschool children (60.20%). Age was negatively correlated with the anti-HBs positivity rate (P<0.001). No significant gender differences in anti-HBs positivity rates were observed. The anti-HBs positive rate in rural areas was higher than that in urban areas, with statistically significant differences across school grade groups (primary grades 1‒3, grades 4‒6, middle school, and high school) (P<0.001). ConclusionThe anti-HBs positivity rate among preschool and school-age children in Tonglu County decreases with age and remains relatively low. It is recommended to strengthen the monitoring of hepatitis B antibody levels and promote health education among preschool and school-age children. Children who have not completed the full hepatitis B vaccination should receive timely catch-up vaccination.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

The clinical efficacy advantages of traditional Chinese medicine （TCM） compound prescriptions have always been inadequately characterized in experimental research，which has become a bottleneck restricting the development of TCM pharmacology and even the progress of TCM. The concept of simultaneous treatment/regulation，guided by the theory of mutual generation and restriction of five zang-organs，has guiding significance in the clinical practice of TCM throughout history and is still widely used in the current clinical practice. However，this unique and clinically valuable diagnostic and therapeutic medication system based on the syndrome differentiation has been completely ignored in the modern research of TCM pharmacology，which might be one of the key factors restricting the pharmacological characterization of the therapeutic advantages of TCM compound prescriptions. On the basis of systematically summarizing the phased progress and achievements of the efficacy evaluation of TCM compound prescriptions，this article explores the path of exploring the pharmacological advantages of TCM compound prescriptions on simultaneous treatment/regulation on the basis of the correlation patterns of five zang-organs，from the theory of Zangxiang，the core concept of five zang-organs，and the TCM disease recognition based on the theory of mutual generation and restriction of five zang-organs. With the heart-lung correlation as a breakthrough point，this study explored a new characterization method for the pharmacological advantages of TCM，aiming to provide new ideas for evaluating the efficacy of TCM compound prescriptions.

ObjectiveThis study explores the efficacy and pharmacological mechanism of Wujiwan in rats with inflammatory bowel disease （IBD） from the perspectives of the peroxisome proliferator-activated receptor γ （PPARγ） signaling pathway and T-cell immunity， providing reference for the treatment of IBD with traditional Chinese medicine. MethodThe study involved administering 2，4，6-trinitrobenzenesulfonic acid （TNBS） enemas to 35 rats to induce acute IBD. After 24 hours， the animals were divided into the following groups： normal group， model group， Wujiwan treatment group， and positive drug control group. Each group received gastric gavage for 8 consecutive days before the rats were dissected to compare the disease activity index （DAI） of the rat colon tissue， the colon mucosal damage index （CMDI）， and the spleen index. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin-1β （IL-1β）， interleukin-10 （IL-10）， and tumor necrosis factor-α （TNF-α） in the serum. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to determine the mRNA expression levels of T-bet （T-box expressed in T cells） and Gata3 （Gata-binding protein-3） in the colon tissue. Western blot analysis was conducted to detect the protein expression levels of PPARγ， T-bet， and nuclear factor-κB p65 （NF-κB p65） in the rat colon. ResultThe rat model of IBD was successfully established. Compared with the model group， the Wujiwan treatment group showed reduced DAI， CMDI， and spleen index， decreased content of TNF-α in the serum（P<0.01）， significantly increased content of IL-10（P<0.01）， and elevated mRNA content of T-bet and Gata3（P<0.05） in the colon tissue. The expression of PPARγ protein was augmented（P<0.05）， and the expression of T-bet and NF-κB p65 protein was decreased（P<0.05，P<0.01）. ConclusionWujiwan activates or upregulates PPARγ expression in IBD rats to inhibit the generation of pro-inflammatory factors， participates in the inflammatory immune process， and alleviates inflammatory reactions. Its mechanism may involve regulating the NF-κB pathway through PPARγ， enhancing Th2 cell transcription expression， and reducing Th1 cell transcription.

Dementia in traditional Chinese medicine （TCM） mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course， and the drugs that can reverse the disease course remain to be developed. Therefore， early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors， cognitive functions， and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases， being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore， early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy， and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage， and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia， the apathetic behaviors of dementia animal models， the behaviors of patients with apathy， and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.

Traditional Chinese medicine （TCM） has a long history of application in China and has consistently played a vital role in treating diseases and saving lives. TCM prescriptions （compounds） constitute the primary form of clinical TCM treatment and significantly differ from western medicine （chemicals） due to the diverse composition and chemical constituents of TCM （compounds）. Nevertheless， the potential multi-component， multi-target， and multi-pathway action characteristics of TCM prescriptions also demonstrate their possible （complementary） therapeutic advantages when compared with single-component chemical drugs. Therefore， driven by the development of modern science and technology and the demands of the modernization and internationalization of TCM， modern theories regarding the complexity of TCM prescription effects have been continuously proposed： Different from the abstract language of traditional prescription theory， the modern TCM prescription theory is more inclined to illustrate the connotation of prescription compatibility concretely and vividly from an experimental and scientific perspective. In this paper， new theories on the complexity of TCM prescriptions proposed in recent years are summarized to provide research references and ideas for the greater role of TCM prescriptions and a better scientific understanding.

Objective:To grasp the degree of coordinated development and spatial distribution characteristics of medical service prices,medical service capacity and regional economic level,so as to promote the benign and coordinated development of medical service prices and various systems.Methods:The entropy value method is used to calculate the comprehensive evaluation index of medical service price,medical service capacity and regional economic level in the sample provinces,and the coupling coordination degree model is used to analyze the degree of coupling coordination between medical service price,medical service capacity and regional economic level in the sample provinces,and carry out spatial autocorrelation analysis.Results:The price of medical services was moderately coupled to the capacity of medical services and the level of the regional economy,and there was moderate dependence between the systems;the price of medical services was poorly coordinated with the capacity of medical services and the level of the regional economy;the coordination between the current price of medical services in China and the capacity of medical services and the level of the regional economy did not have a spatial aggregation and radiation effect in space.Conclusion:Coordination between the price of medical services in China and the capacity of medical services and regional economic level needed to be strengthened urgently.Suggestion:The capacity of medical services should be quantitatively evaluated and the formation of medical service prices should be guided,the coordination and linkage between medical service prices and macroeconomic levels should be strengthened,and efforts should be made to enhance the regional equilibrium of China's medical service price policy.

Objective To analyze the current status,research hotspots and development trends in the field of immune responses in the microenvironment after spinal cord injury(SCI). Methods Literatrues about immune responses in the microenvironment after SCI were searched from CNKI and the Web of Science Core Collection,from inception to March,2024.VOSviewer and CiteSpace were used to conduct a vi-sual analysis of authors,countries,institutions,journals,co-cited references and keywords.

Conclusion Immune responses in the microenvironment have emerged as a central focus in SCI research.The emphasis of current researches is shifting from mechanistic exploration to the investigation of immunomodulatory strate-gies,with several cutting-edge technologies showing significant potential in this regard.Moving forward,increas-ing collaboration across regions and institutions are essential to promote information sharing,accelerate scientific progress,and facilitate clinical translation,ultimately enhance patient rehabilitation outcomes.

This paper discusses the treatment of polycystic ovary syndrome(PCOS)based on the midnight-noon ebb-flow theory.The midnight-noon ebb-flow theory is a Chinese medicine science that combines the time and space of nature with the internal rhythm of the human body.PCOS is characterized by disappearance of the reproductive monthly rhythm.Its etiology is based on kidney deficiency.The key to its pathogenesis is the excess of yin and deficiency of yang,the hyperactivity of yang and deficiency of yin,and the lack of smooth connection between yin and yang.PCOS patients have circadian rhythm disorders,and the oscillation of the core clock gene is attenuated,which leads to the interruption of the circadian rhythm gene in the ovary,the imbalance of yin and yang trans-formation in the kidney,and the asynchrony of qi and blood flow with the time rhythm.Therefore,the treatment focuses on harmonizing yin and yang and rebuilding the normal reproductive rhythm of women.Using the midnight-noon ebb-flow theory,combined with the reproductive physiological characteristics of women,choosing different drug administration time and selecting meridians and acupoints according to the time will be helpful to unlock the"time code"of the female reproductive system,and assist clinical menstruation regu-lation,pregnancy and treatment of diseases.

Objective:To investigate the immunophenotypic and molecular biological characteristics of patients with elevated serum alpha-fetoprotein (AFP) and enteroblastic differentiated gastric adenocarcinoma (GAED).Methods:The clinicopathological data of 13 patients with elevated serum AFP and GAED admitted to Shanxi Cancer Hospital from 2018 to 2020 were collected. Immunohistochemistry (IHC) and next-generation sequencing (NGS) were used to analyze the immune markers and molecular biological characteristics of the pathological tissues of the patients. Kaplan-Meier method and log rank test were used for survival analysis.Results:Among the 13 patients with GAED, 12 were male and 1 was female, aged 41-70 years, with a median age of 64 years. The lesions were mainly located in the gastric antrum (5 cases) and gastric body (4 cases). IHC results showed that the tumor embryonic protein (AFP, SALL4, GPC3), intestinal epithelial differentiation protein (CDX-2, CD10), and some original intestinal epithelial phenotype markers (OCT3/4, Claudin6) were expressed in the tumor tissues. Combined application of multiple markers can reduce the rate of missed diagnosis. Among the 13 patients, 12 had at least one mutation (1 mutation: 1 case, 2-5 mutations: 3 cases, 6-15 mutations: 8 cases), and 1 case was not detected. The gene with the highest mutation frequency was TP53 (10 cases), and other mutant genes included EPHB1 (3 cases), ATRX (2 cases), EPHA5 (2 cases), GATA3 (2 cases), LRP1B (2 cases) and MAP2K4 (2 cases) were also detected. Three of the 13 patients had structural variations, which were C14orf177- GNAS, AIM1- FGFR3, and EPHA6- ROS1 gene rearrangements. All 13 patients had copy number variation, and 11 patients had copy number variation of more than 2 genes. The common amplification genes were IRS2 (5 cases), PTEN (5 cases), GNAS (4 cases), CCNE1 (3 cases), CEBPA (3 cases), PCK1 (3 cases) and ERBB2 (2 cases). The common deletion genes were SOX2 (5 cases) and MYC (5 cases). Among the 13 patients, 4 died, and 2 of the dead patients had liver metastasis. There were 4 patients with disease-free survival and 5 patients with disease progression, including 3 cases of abdominal metastasis and 2 cases of liver metastasis. The 3-year survival rate of patients was 65.9 %, and the 3-year progression-free survival rate was 30.7 %. Gene LRP1B point mutation was associated with poor prognosis ( P＜0.001). There was no significant improvement in the prognosis of patients treated with immunotherapy compared with those treated with chemotherapy alone ( P=0.595), but the prognosis of patients treated with postoperative chemotherapy or postoperative chemotherapy plus immunotherapy was better than that of patients treated with surgery alone ( P＜0.05). Conclusions:Elevated serum AFP with GAED is a highly invasive tumor with unique molecular characteristics, often accompanied by multiple molecular events. TP53 mutation is the most common type of gene mutation. In addition, some cases are accompanied by HER2 amplification and gene rearrangement.
