Objective:To investigate the significance of urinary 8-oxo-7, 8-dihydroguanosine(8-oxoGuo)in assessing the short-term prognosis of sepsis in frail elderly patients.Methods:We conducted a cross-sectional study involving 62 frail elderly patients diagnosed with sepsis who were admitted to the Emergency Intensive Care Unit(EICU)at Beijing Hospital between March 2021 and March 2022.Based on their 28-day prognosis, the patients were categorized into two groups: those who died and those who survived.Upon admission, we collected urine samples and clinical data from both groups.We employed isotope dilution high-performance liquid chromatography-mass spectrometry to measure the levels of the RNA oxidation marker 8-oxoGuo in the urine.Results:A total of 62 frail elderly patients[aged(85.1±6.3)years]diagnosed with sepsis were included in the study, comprising 36 patients in the 28-day mortality group and 26 patients in the survival group.Univariate analysis revealed that the survival group had significantly lower body temperature, blood calcitonin(PCT)levels, sequential organ failure assessment(SOFA)scores, and urinary 8-oxoGuo levels compared to the mortality group.Additionally, the survival group exhibited a higher mean arterial pressure(MAP)than the mortality group, with all differences reaching statistical significance(all P<0.05).Spearman correlation analysis indicated that urinary 8-oxoGuo levels were positively correlated with both PCT and SOFA scores in frail elderly sepsis patients( r=0.426, 0.768, both P<0.05).Furthermore, logistic regression analysis identified urinary 8-oxoGuo and SOFA as independent risk factors for 28-day mortality in this population( OR=1.936, 1.427; P=0.006, 0.002).The area under the receiver operating characteristic curve(AUC)for urinary 8-oxoGuo and SOFA in predicting the 28-day prognosis of frail elderly sepsis patients was 0.761 and 0.741, respectively, both demonstrating statistical significance(both P<0.001). Conclusions:Our findings suggest that urinary 8-oxoGuo possesses strong predictive value for the short-term prognosis of sepsis in this vulnerable population.

Objective To analyze the pattern of group medication in Parkinson's disease cognitive disorders based on data mining.Methods The famous TCM experience and effective clinical treatment of cognitive impairment in the treatment of Parkinson's disease were retrieved in databases of CNKI,Wanfang and Weipu,from the founding of the databases to August 2024.Medication rules were analyzed.Results A total of 60 Chinese prescriptions were included,including 120 traditional Chinese medicines.High-frequency drugs for the treatment of cognitive impairment in Parkinson's disease included Radix Rehmanniae Praeparata,Radix Paeoniae Alba,Rhizoma Gastrodiae Praeparata,Fructus Lycii,Herba Cistanches,Acorus Calamus and others.The flavour of the medicine were mainly sweet,bitter and pungent,the nature of the medicine was mainly warm,cold and calm and the meridians of the medicine were mainly liver,kidney and heart.Radix Rehmanniae Praeparata-Comu Cervi Pantotrichum,Rhizoma Gastrodiae Praeparata-Hooker's Tree,Radix Rehmanniae Praeparata-Cistanches are the commonly used pairs;Lycium barbarum-Cornus officinalis-Radix Rehmanniae Praeparata,Radix Rehmanniae Praeparata-Radix Angelicae Sinensis-Radix Paeoniae Alba were commonly used combination.Cluster analysis yielded 5 broad categories.Conclusion The primary pharmacological agents employed in traditional Chinese medicine to address cognitive impairment associated with Parkinson's disease emphasize the replenishment of essence and nourishing the marrow.These agents are complemented by nootropic substances that facilitate bodily openness,promote liver health,alleviate wind,resolve phlegm,and invigorate blood circulation and meridian pathways,worth of clinical promotion and application.

Objective To examine of Ye Tianshi's approach to managing internal wind through herbal remedies.Methods A comprehensive search was conducted for medical cases pertaining to internal wind,liver wind,dizziness,head wind,deficiency labor,liver fire,insomnia,convulsions,epilepsy,and headache within the Clinical Guidelines in Medical Cases.Statistical analysis of symptom elements,target locations of symptom elements,frequency of Chinese medicinal substances,their properties,and meridian affiliations was performed using Excel.Prescription patterns were further analyzed through association rules and high-frequency drug clustering.Results The study included a total of 167 medical cases,from which 241 symptom elements and 333 target locations were extracted.A total of 183 prescriptions were analyzed,comprising 132 medicinal substances with an overall frequency of 1309 occurrences.The five most frequently used Chinese medicines were Sheng Di Huang,Fu Shen,E Jiao,Fu Ling,and Shu Di Huang.The predominant property observed was cold,followed by warm and neutral;the most common flavor was sweet,succeeded by bitter and warm.The leading meridian affiliations identified were liver,kidney,lung,heart,and spleen.The drug association rule analysis revealed 14 items,while high-frequency drug clustering resulted in 9 distinct categories.Conclusion Ye Tianshi's therapeutic approach to internal wind emphasizes the concept of"yang transforming into internal wind."The core principles of this treatment strategy involve nourishing bodily fluids to mitigate wind,addressing excess conditions in the upper body while rectifying deficiencies in the lower body,and promoting tranquility in the liver and stomach.Additionally,the use of pungent and sweet flavors is employed to facilitate the transformation of wind,to clear the liver and dispel heat,to eliminate wind and resolve phlegm,to tonify qi and enhance defensive qi,and to clear heat in order to soothe the spirit.This methodology seeks to achieve harmony among the organs and meridians while pacifying internal wind.

Antibody-based therapies are one of the crucial tumor-targeted therapies,enabling pre-cise elimination of tumor cells by specifically binding to antigens on the tumor cell surface.However,their wide applications in solid tumor therapy are often limited by on-target toxicity.Recent advance-ments in antibody engineering have led to the development of novel tumor-targeted masking antibod-ies,which are specifically designed to address these limitations.Masking antibodies typically consist of an antibody domain,a masking domain and a linker.These antibodies are characterized by selective activation and other functional properties.Currently,various masking antibody technologies with distinct characteristics have been developed and have demonstrated favorable safety profiles in animal studies.This review summarizes the structure and characteristics of tumor-targeted masking antibodies outlines common masking technologies and their drug development in order to offer new lines of thought for the design and development of next-generation tumor-targeted therapeutics.
