With the accelerating process of population aging, binocular vision disorders have become increasingly prevalent, posing new challenges for both social aging strategies and ophthalmic clinical practice. Non-strabismic binocular vision anomalies(NSBVAs)are notably prevalent among elderly populations; however, current research predominantly focuses on the abnormality rates derived from individual binocular vision clinical tests, while data on the actual prevalence based on comprehensive diagnostic criteria remain limited. This review synthesizes existing scientific literature to provide a concise yet comprehensive overview of the prevalence, risk factors, and clinical diagnostic methods of NSBVAs in pre-presbyopic and presbyopic populations, with an in-depth examination of age-related changes in binocular vision function among older adults. By integrating and comparing analyses of the correlations between age and various binocular vision parameters, this review aims to enhance understanding of age-related binocular vision dysfunction and establish a theoretical foundation for developing targeted diagnostic and therapeutic approaches. Ultimately, these insights could contribute to improved visual performance and life satisfaction in elderly individuals.

Objective:
To investigate the survival rate of female breast cancer patients in Panyu District, Guangzhou City, so as to provide the basis for improving the prognosis of breast cancer patients.
Methods:
Basic information including age, clinical stage and surgical treatment of female breast cancer patients registered in Panyu District and diagnosed in 2017 were collected through the Guangzhou Municipal Cancer Registration and Reporting Management System, and were followed up until December 31, 2022. The survival rate was calculated using the life table. Factors affecting survival time among female breast cancer patients were analyzed using a multivariable Cox proportional hazard regression model.
Results:
A total of 227 female breast cancer patients were reported in Panyu District in 2017, and had a median age of 51 (interquartile range, 17) years. There were 43 cases (18.94%) in stage Ⅰ, 55 cases (24.23%) in stage Ⅱ, 63 cases (27.75%) in stage Ⅲ, 27 cases (11.89%) in stage Ⅳ, and 39 cases (17.18%) with unknown staging. Surgical treatment was performed in 204 cases (89.87%), and chemotherapy was administered in 73 cases (32.16%). By December 31, 2022, there were 40 deaths and 14 patients lost to follow-up. The one-year, three-year and five-year survival rates were 96.44%, 87.45% and 82.87%, respectively. Multivariable Cox proportional hazard regression analysis showed that older age (HR=1.023, 95%CI: 1.002-1.046), clinical stage Ⅲ (HR=10.050, 95%CI: 1.324-76.270) or IV (HR=42.663, 95%CI: 5.588-325.742) were associated with a higher risk of mortality in female breast cancer patients, while surgical treatment (HR=0.278, 95%CI: 0.130-0.598) was associated with a lower risk of mortality.
Conclusions
The five-year survival rate of female breast cancer patients in Panyu District was 82.87%. Age, clinical stage and surgical treatment were the main influencing factors for the survival time of female breast cancer patients.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the distribution characteristics and analyze the clinical significance of dermatophagoides pteronyssinus allergen components in children with allergic rhinitis and asthma in Shenzhen.Methods:This study was a cross-sectional study. The clinical data of children with allergic rhinitis and asthma induced by dust mites admitted to the allergy clinic of Shenzhen Children′s Hospital from 2021 to 2024 were collected and the serum sIgE levels of dermatophagoides pteronyssinus, dermatophagoides farinae (Der p, Der f) and dermatophagoides pteronyssinus components (Der p 1, Der p 2, Der p 10, Der p 23) were detected by magnetic bead chemiluminescence method. The correlation between dermatophagoides pteronyssinus allergen components and clinical data of children was analyzed. According to the diagnosis, the children were divided into allergic rhinitis (AR) group and AR with asthma (ARAS) group. According to the age, the children were divided into preschool age (5 years ≤age<7 years), school age (7 years ≤age<10 years) and adolescence (10 years ≤age≤15 years). The expression differences of dermatophagoides pteronyssinus components among AR group and ARAS group and different age groups were compared.Results:A total of 314 children with allergic rhinitis and asthma caused by dust mites were included in the study, of whom 112 were male and 202 were female. There were 188 cases of AR and 126 cases of ARAS, aged 5-15 years, with a median age of 7.54 years and an average age of (8.02±2.24) years. BMI was 13.89-31.76 kg/m 2,the median BMI was 15.87 kg/m2 and average BMI was (16.55±3.05) kg/m2. There was not statistically significant difference in gender, age, BMI, blood eosinophils, blood basophils, FeNO, FVC and FEV1 between the AR group and the ARAS group ( P>0.05). There was significant difference in FEV1/FVC and small airway function indexes MMEF, MEF75%, MEF50% and MEF25% between the AR group and the ARAS group ( P<0.05). In the 314 children, the dermatophagoides pteronyssinus allergen components sensitization rates were in the order of Der p 1 (97.1%), Der p 2 (89.8%), Der p 23 (55.1%), Der p 10 (8.6%), and the difference in the positive rate was statistically significant (χ 2=658.31, P<0.001). There was not significant difference in Der p 1, Der p 2 and Der p 10 among children of different ages ( P>0.05). There was significant difference in Der p 23 among children of different ages (χ 2=7.29, P=0.03). A correlation analysis showed that Der p, Der f, Der p 1 and Der p 2 had a high positive correlation ( P<0.001). Eosinophils are positively correlated with Der p, Der f, Der p 1, Der p 2, Der p 10 and Der p 23 ( P<0.001). FeNO is positively correlated with Der p, Der f, and Der p 23 ( P<0.05). Small airway function indicators MMEF, MEF50% and MEF25% are negatively correlated with Der p, Der f and Der p 1 ( P<0.05). The sIgE levels of Der p, Der f, Der p 1, Der p 2 and Der p 10 in the AR group were significantly lower than those in the ARAS group ( P<0.05). In the ARAS group, 120 cases (95.24%) showed positive results for at least 2 dermatophagoides pteronyssinus components, while 71 cases (56.35%) showed positive results for at least 3 dermatophagoides pteronyssinus components. In the AR group, 171 cases (90.96%) showed positive results for at least 2 dermatophagoides pteronyssinus components, while 94 cases (50.00%) showed positive results for at least 3 dermatophagoides pteronyssinus components. Conclusion:Der p 1, Der p 2 and Der p 23 may be the main dermatophagoides pteronyssinus allergen components that induce allergic rhinitis and asthma in Shenzhen City. The elevation of sIgE levels in the dermatophagoides pteronyssinus components can aggravate the severity of lower airway eosinophilic inflammation and airway obstruction. Attention should be paid to the detection of dermatophagoides pteronyssinus components in children with poor response to dust mite-allergen specific immunotherapy.

Objective:To investigate the molecular mechanisms of chronic rhinosinusitis (CRS), to identify key cell subgroups and genes, to construct effective diagnostic models, and to screen for potential therapeutic drugs.Methods:Key cell subgroups in CRS were identified through single-cell transcriptomic sequencing data. Essential genes associated with CRS were selected and diagnostic models were constructed by hdWGCNA (high dimensional weighted gene co-expression network analysis) and various machine learning algorithms. Causal inference analysis was performed using Mendelian randomization and colocalization analysis. Potential therapeutic drugs were identified using molecular docking technology, and the results of bioinformatics analysis were validated by immunofluorescence staining. Graphpad Prism, R, Python, and Adobe Illustrator software were used for data and image processing.Results:An increased proportion of basal and suprabasal cells was observed in CRS, especially in eosinophilic CRS with nasal polyps (ECRSwNP), with P=0.001. hdWGCNA revealed that the "yellow module" was closely related to basal and suprabasal cells in CRS. Univariate logistic regression and LASSO algorithm selected 13 key genes ( CTSC, LAMB3, CYP2S1, TRPV4, ARHGAP21, PTHLH, CDH26, MRPS6, TENM4, FAM110C, NCKAP5, SAMD3, and PTCHD4). Based on these 13 genes, an effective CRS diagnostic model was developed using various machine learning algorithms (AUC=0.958). Mendelian randomization analysis indicated a causal relationship between CTSC and CRS (inverse variance weighted: OR=1.06, P=0.006), and colocalization analysis confirmed shared genetic variants between CTSC and CRS (PPH4/PPH3>2). Molecular docking results showed that acetaminophen binded well with CTSC (binding energy:-5.638 kcal/mol). Immunofluorescence staining experiments indicated an increase in CTSC +cells in CRS. Conclusion:This study integrates various bioinformatics methods to identify key cell types and genes in CRS, constructs an effective diagnostic model, underscores the critical role of the CTSC gene in CRS pathogenesis, and provides new targets for the treatment of CRS.

OBJECTIVE To explore the practicality of the pharmaceutical pathway for prophylactic use of antibiotics during the perioperative period of class Ⅰ neurosurgery incisions. METHODS The previously established pharmaceutical pathway for the prophylactic use of antibiotics in the perioperative period of class Ⅰ neurosurgery incisions was used to retrospectively evaluate the prophylactic use of antibiotics in 127 cases. The “antibiotics prophylactic use scoring system” in the pharmaceutical pathway was used to conduct preoperative scoring, and the patient’s actual antibiotics use was compared and analyzed in combination with existing Guiding Principles for Clinical Application of Antibiotics (2015 Edition) (hereinafter referred to as the Guiding Principles). The pharmaceutical pathway also innovatively proposes key points for improvement in terms of the frequency of adding antibiotics during surgery and the duration of prophylactic use of antibiotics after surgery. By comparing with the actual medication situation of patients, the direction for updating the Guiding Principles was explored. RESULTS According to the retrospective analysis results, for neurosurgery class Ⅰ incision surgery, in addition to the preoperative prophylactic use of antibacterial drugs for skull mass resection and carotid endarterectomy recommended in the guidelines, endoscopic trigeminal microvascular decompression, arthroscopy and other specific joint examinations, spinal nerve Radical decompression, endoscopic lumbar nucleectomy, dural repair, and spinal canal decompression can also be further explored about the situation of not using antibacterial prophylaxis before surgery; at the same time, for the patients undergoing class Ⅰ neurosurgery incisions, the use of antibiotics during and after surgery may be considered for a second addition of antibiotics, taking into account the surgical time. If cerebrospinal fluid leakage occurred after surgery, it is recommended to extend the duration of prophylactic use of antibiotics appropriately. CONCLUSIONS The application of pharmaceutical pathways can provide more targeted analysis of key points in the prevention of antibiotic use, which promotes the transformation of perioperative antibiotics management for class Ⅰ incisions from “qualitative, empirical” management to “quantitative, scientific” management.
