Prostate cancer is one of the most common malignant tumors of male genitourinary system. Prostate cancer has the following characteristics： insidious onset， early asymptomatic or not obvious symptoms， complex etiology and pathogenesis， long incubation period and so on. Therefore， the realization of its early diagnosis and treatment is of great significance to the prognosis of patients. Prostate-specific membrane antigen （PSMA） is a type 2 transmembrane glycoprotein that is highly expressed on the membrane of almost all primary and metastatic prostate cancer cells， and is an ideal target for prostate cancer imaging and treatment. In recent years， with the approval of urea-containing small molecule PET （positron emission computed tomography） radiopharmaceutical based on PSMA （⁶⁸Ga-PSMA-11， ¹⁸F-PSMA-1007）， PET-CT （positron emission computed tomography/computed tomography） has shown new potential for early diagnosis and accurate staging of prostate cancer patients. This review mainly summarizes the research progress of urea-containing PSMA PET imaging agents and finds that they have defects such as uptake in non-target tissues like the kidneys， lacrimal glands， and salivary glands. Thus， further optimizing their structure to reduce the uptake in non-target tissues， providing provide convenience for the labeling of therapeutic radiopharmaceuticals， thereby achieving the goal of integrated diagnosis and treatment， is an important development direction in this field.

The c-Jun N-terminal kinase （JNK） signaling pathway， a key member of the mitogen-activated protein kinase （MAPK） family， plays a central role in the pathogenesis and progression of central nervous system （CNS） diseases by regulating core biological processes such as apoptosis， inflammatory responses， synaptic plasticity， and autophagy. This article sorts out and analyzes relevant literature published domestically and internationally in recent years， summarizing the mechanisms of action of the JNK signaling pathway in common CNS diseases and the research progress in traditional Chinese medicine （TCM） interventions in CNS diseases through the regulation of the JNK signaling pathway. Studies have shown that active components of TCM， such as berberine， paeoniflorin， and astragaloside Ⅳ， as well as compound formulations like Heixiaoyao san， Ditan tang， and Buyang huanwu tang， can exert neuroprotective effects in various CNS disorders， including Alzheimer’s disease， Parkinson’s disease， cerebral ischemia-reperfusion injury， and epilepsy， by inhibiting the aberrant activation of the JNK signaling pathway， thereby alleviating neuroinflammation， oxidative stress， and neuronal apoptosis， while improving synaptic function and cognitive behavioral deficits， regulating autophagy， and maintaining blood-brain barrier integrity.

Alzheimer’s disease （AD） is an age-related neurodegenerative disorder. Marrow-sea insufficiency serves as the fundamental basis for the onset of AD. Early syndrome differentiation-based intervention helps to delay disease progression， and improve patients’ cognitive function. Qifu yin is a representative specialized prescription for AD with marrow-sea insufficiency syndrome. Studies demonstrate that Qifu yin exerts neuroprotective effects through multiple pathways， including inhibiting the abnormal deposition of amyloid β -protein and hyperphosphorylation of tau protein， alleviating neuroinflammation， regulating oxidative stress and mitochondrial dysfunction， modulating the cholinergic system， and improving synaptic plasticity. Qifu yin combined with Western medicine such as donepezil， memantine， and butylphthalide， or combined with external therapies such as acupuncture， can effectively improve cognitive function and activities of daily living in AD patients with favorable safety. Future research should focus on the core pathogenesis and key targets of AD with marrow-sea insufficiency syndrome， provide in-depth elucidation of the scientific connotation of Qifu yin’s “tonifying the kidney to produce marrow”， and further conduct high-quality clinical studies to provide scientific evidence for the prevention and treatment of AD with marrow-sea insufficiency syndrome.

ObjectiveTo establish three standardized rehabilitation unit models covering acute, critical and comprehensive recovery stages for traumatic brain injury (TBI) that fit the whole-course characteristics, clarify their multidisciplinary collaborative framework, standardized procedures, and information management system, and verify the clinical effectiveness of this staged rehabilitation unit on long-term functional prognosis and in-hospital complications of TBI patients. MethodsThis study was conducted at two stages: model construction and efficacy verification. At the first stage, TBI rehabilitation units for acute, critical and recovery stages were established in the Department of Neurosurgery, Intensive Care Unit and Department of Rehabilitation Medicine, respectively, with unified multidisciplinary team configuration, standardized assessment and treatment protocols, collaborative workflows, and a dedicated information management system. At the second stage, 324 TBI patients admitted to the newly built rehabilitation units from July, 2023 to July, 2025 were enrolled as the observation group, and 167 TBI patients receiving traditional management from January, 2018 to December, 2022 were retrospectively selected as the control group. The primary outcomes were 1-year post-injury Glasgow Outcome Scale (GOS) and Disability Rating Scale (DRS) scores. Secondary outcomes included the incidence of in-hospital complications and the mean indwelling time of tracheal intubation, gastric tube and urinary catheter. ResultsThe 1-year GOS score was significantly higher (t = -7.836, P < 0.001), and the DRS score was significantly lower (t = -6.742, P < 0.001) in the observation group than in the control group. The overall incidence of complications was significantly lower in the observation group than in the control group (χ² = 18.762, P < 0.001). The incidences of pulmonary infection, urinary tract infection, pressure ulcer, lower extremity venous thrombosis and joint contracture deformity were all significantly reduced (χ² > 4.328, P < 0.05). The indwelling time of tracheal intubation, gastric tube and urinary catheter was significantly shorter in the observation group than in the control group (t > 10.276, P < 0.001). ConclusionThe acute-critical-comprehensive three-stage standardized TBI rehabilitation unit could significantly improve the long-term functional outcomes of TBI patients, reduce the incidence of complications, and shorten the indwelling time of invasive tubes through multidisciplinary collaboration, whole-course standardized management and information-based quality control. This model conforms to the pathological and functional laws of TBI, realizes seamless whole-course connection from acute treatment to recovery rehabilitation, and has good clinical feasibility and promotion value. It can provide evidence-based evidence and practical reference for the homogenized and standardized development of TBI rehabilitation in China.

Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

ObjectiveTo explore the changes in volatile components， total polysaccharides， enzyme activity， and chromaticity value of Myristicae Semen Koji（MSK） during the fermentation process， and conduct correlation analysis. MethodsBased on gas chromatography-mass spectrometry（GC-MS）， the changes of volatile components in MSK at different fermentation times were identified. The phenol sulfuric acid method， dinitrosalicylic acid method（DNS）， and carboxymethyl cellulose sodium salt method（CMC-Na） were used to investigate the total polysaccharide content， amylase activity， and cellulase activity during the fermentation process. Visual analysis technology was used to explore the changes in chromaticity values， revealing the fermentation process of MSK and the dynamic changes of various measurement indicators， partial least squares-discriminant analysis（PLS-DA） was used to explore the differential compounds of MSK at different fermentation degrees， and Pearson correlation analysis was used to explore the correlation between volatile components of MSK and total polysaccharides， enzyme activity， and chromaticity values. ResultsA total of 60 volatile compounds were identified from MSK， the relative contents of components such as （+）-α-pinene， β-phellandrene， β-pinene， （+）-limonene， and p-cymene obviously increased， while the relative contents of components such as safrole， methyl isoeugenol， methyleugenol， myristicin， and elemicin significantly decreased. During the fermentation process， the total polysaccharide content showed an upward trend， while the activities of amylase and cellulase showed an initial increase followed by a decrease， and reached their maximum value at 40 h. the overall brightness（L^*） and total color difference（ΔE^*） gradually increased， while the changes in red-green value（a^*） and yellow-blue value（b^*） were not obvious. PLS-DA results showed that MSK could be clearly distinguished at different fermentation times， and 13 differential biomarkers were screened out. Pearson correlation analysis results showed that the contents of α-terpinene， β-phellandrene， methyleugenol， β-cubebene and myristic acid had an obvious correlation with chromaticity values. ConclusionAfter fermentation， the volatile components， total polysaccharides， amylase activity， and cellulase activity of MSK undergo significant changes， and there is a clear correlation between them and chromaticity values， which reveals the dynamic changes in the fermentation process and related indicators of MSK， laying a foundation for the quality control.

Objective:To summarize the clinical characteristics and treatment experience of patients with botulism after cosmetic botulinum toxin injection.Methods:A retrospective study was conducted on patients admitted to the Department of Medical Aesthetic and Plastic Surgery of the Fifth Affiliated Hospital of Zhengzhou University for botulism after cosmetic botulinum toxin injection between January 1, 2023, and October 31, 2024. Clinical data and treatment regimens were collected. Patients received botulinum antitoxin injection, neurotrophic therapy, nutrition supplementation, modulation and enhancement of cellular immune function, and systemic supportive care based on their condition. Prior to antitoxin administration, a skin test was performed. Patients with a negative test received intramuscular injections of 10 000 U of antitoxin serum every 12 hours, while those with a positive result underwent a desensitization protocol. The cessation criterion was significant improvement of toxic symptoms. Data collected included age, gender, region, time of presentation, injection location, brand and type of toxin, injection time, sites and dose of injection, time to onset of initial symptoms, main symptoms, skin test result for antitoxin, dosage of antitoxin administered, length of hospital stay, adverse reactions and prognosis. Data analysis was performed using GraphPad Prism Version 10.2.0.Results:A total of 179 patients were included, with 8 cases in 2023 and 171 cases in 2024. The majority were female (97.2%, 174 cases). The age range was 18-62 years, with a median age of 35 years; the highest proportion was in the 20-40 age group (71.5%, 128 cases). Patients were from 23 different provinces, autonomous regions, and municipalities directly under the central government in China. The injected product was mostly an unspecified brand of botulinum toxin (57.5%, 103 cases). Injections were primarily administered in non-medical institutions, with beauty salons or private studios accounting for 88.8% (159 cases). Injection sites included the platysma (92 cases), masseter muscle (82 cases), orbicularis oculi muscle (82 cases), frontalis muscle (67 cases), among others, with some patients receiving injections at multiple sites. 69 cases (38.5%) of patients were unaware of the injected dose; for the remaining cases, based on information provided, the injected doses were all within the safe range. The incubation period was mostly 1-7 days. The main symptoms included fatigue (171 cases), dysphagia (137 cases), dizziness (101 cases), blurred vision (76 cases), and difficulty opening eyes (66 cases). 176 patients received botulinum antitoxin treatment; 82 cases (46.6%) had a positive skin test and received desensitization injections, while 94 cases (53.4%) had a negative test. The total dosage of antitoxin used ranged from 10 000 U to 240 000 U. Three patients received only adjuvant therapy such as neurotrophic support. Adverse reactions during treatment primarily included induration at the injection site and serum sickness, all of which resolved after symptomatic treatment with antihistamines, steroids, etc. The hospital stay ranged from 1 to 24 d, with an average of 4.6 d. Upon discharge, symptoms in all patients had alleviated or resolved. At the 6-month follow-up after discharge, 14 patients were lost to follow-up; the remaining patients recovered well with no other complications.Conclusion:Poisoning incidents due to the illegal or improper use of botulinum toxin are increasing. Administration of botulinum antitoxin is an effective means to ameliorate intoxicating symptoms. Patients should seek timely medical intervention and receive antitoxin treatment as early as possible. Desensitization administration does not affect the efficacy of the antitoxin.

OBJECTIVE To investigate the relationship between M2-type macrophages and immunotherapy prognosis in head and neck squamous cell carcinoma.METHODS 165 patients with head and neck squamous cell carcinoma who received immunotherapy in Tangshan People's Hospital from April 2021 to May 2022 were selected as the study objects.According to the number of CD163 positive cells,the patients were divided into high expression group(n=75)and low expression group(n=90),and the relationship between the expression level of M2 macrophages and clinical characteristics was analyzed.Patients were divided into death group(n=62)and survival group(n=103)according to the prognosis.Hierarchical regression model was used to analyze the relationship between different clinical features and M2 macrophages,and Logistic regression was used to analyze the relationship between M2 macrophages and prognosis.The association and dose-response relationship between M2-type macrophages and death were analyzed by unconditional Logistic regression and restricted cubic spline model.The influence of M2-type macrophages on survival was verified by Kaplan-meier survival curve.REULTS The expression of M2 macrophages was compared in patients with different tumor diameters,T grades,N grades,different degrees of tumor differentiation,lymph node metastasis,and distant metastasis,and the differences were statistically significant(P<0.05).The differences in tumor diameter,T grade,N grade,degree of tumor differentiation,lymph node metastasis,distant metastasis,and expression level of M2 macrophages between the death group and survival group were statistically significant(P<0.05).Hierarchical regression analysis showed that tumor diameter,clinical T stage,clinical N stage,degree of tumor differentiation,lymph node metastasis and distant metastasis had significant effects on M2-type macrophages(P<0.05).After the collinear confounding factors were excluded,the expression level of M2-type macrophage was independently correlated with death(P<0.05).The 1-year survival rate was 82.64%,the 2-year survival rate was 66.77%,and the 3-year survival rate was 60.28%in patients with low expression of M2 macrophages.The 1-year survival rate was 60.11%,2-year survival rate was 42.53%,and 3-year survival rate was 41.82%in patients with high expression of M2 macrophages.There was statistical difference between the two groups(P<0.05).CONCLUSION There is an independent correlation between M2-type macrophages and the prognosis of patients with head and neck squamous cell carcinoma.The high expression of M2-type macrophages will promote the occurrence and development of head and neck squamous cell carcinoma.
