Objective To explore the value of the corrected-size ratio(c-SR)value of intracranial volume computed tomography angiography(CTA)in predicting the risk of intracranial aneurysm rupture.Methods A total of 81 patients with aneurysms who had follow-up records were selected.Among them,39 patients with unruptured aneurysms and underwent regular follow-ups,while 9 patients with unruptured aneurysms opted for surgical intervention.Additionally,surgery was performed on 33 patients with ruptured aneu-rysms.Three-dimensional reconstruction of CTA was performed to obtain the morphological parameters of aneurysms.The initial size ratio(SR)value of aneurysm and the follow-up SR value or postoperative c-SR value were obtained.The changes in SR values of unruptured aneurysms were analyzed,the preoperative SR values and postoperative c-SR values of aneurysms were analyzed.Finally,the correla-tion between the intial SR value of unruptured aneurysms and the c-SR value of ruptured aneurysms was compared.Results No sig-nificant difference was observed between the initial SR value of unruptured aneurysms and the follow-up SR value(P>0.05).Simi-larly,no significant difference was noted between the preoperative SR value of unruptured aneurysms and the postoperative c-SR value(P>0.05).The preoperative SR value of ruptured aneurysms differed significantly from the postoperative c-SR value(P<0.05).There was a significant difference between the initial SR value of unruptured aneurysms and the postoperative c-SR value of ruptured aneurysms(P<0.05).The receiver operating characteristic(ROC)curve analysis was performed on the initial SR value of unrup-tured aneurysms and the postoperative c-SR value of ruptured aneurysms.The area under the curve(AUC)was 0.860 and the best cut-off value was 1.045.Conclusion Unruptured aneurysms remain stable for an extended period of time,exhibiting no significant change in morphological parameters.It can be concluded that surgical intervention does not affect the SR value of aneurysms.In the case of subarachnoid hemorrhage caused by ruptured aneurysms,the parent artery become thinner,then the preoperative SR value of ruptured aneurysms may be exaggerated,which results in the distortion of the preoperative SR value of ruptured aneurysms.However,the postoperative c-SR value is the true SR value before the rup-ture of aneurysms.

Objective:To explore the symptoms of Ménière′s disease patients and their impact on quality of life.Methods:A cross-sectional study was conducted, consecutively enrolling patients of Ménière′s disease who visited the Otolaryngology Clinic at the Eye & ENT Hospital of Fudan University from October 2014 to December 2022. The Chinese version of the Ménière′s Disease Outcomes Questionnaire (MDOQ) and a Ménière′s disease-specific symptom checklist were utilized for assessment. SPSS 25.0 software was employed to perform multiple linear regression analysis to determine the impact of Ménière′s disease symptoms on patients′ quality of life.Results:A total of 790 patients with a definitive diagnosis of Ménière′s disease who met the inclusion and exclusion criteria were analyzed. The cohort comprised 418 males and 372 females, with a mean age of (54.8±13.1) years and a diagnosis duration ranging from 0 to 72 months, with a median of 3 months. The total score of the Chinese MDOQ was 61.0±12.0. The symptomatic presentations of the enrolled patients included hearing changes, tinnitus, aural fullness, drop attacks, vertigo episodes, visual instability, dizziness, and headache. Multiple linear regression analysis revealed that age, tinnitus, aural fullness, frequency of drop attacks, visual instability, dizziness, and headache were significant factors affecting the quality of life in Ménière′s disease patients ( F=145.50, P<0.05). Conclusions:The quality of life in Ménière′s disease patients requires improvement. Attention to the specific symptoms of Ménière′s disease and their impact on patients′ quality of life, along with targeted symptom interventions based on these findings, will be a focal point in future disease management.

Objective To investigate the relationships of nutritional status and length of stay (LOS) with phase angle (PA) in patients with severe craniocerebral injury. Methods A total of 100 patients [Glasgow Coma Scale (GCS) score ≤8 points] admitted outside the department of neurology were selected as study objects. Body composition analysis and blood samples were used to determine the intracellular and extracellular water content, skeletal muscle, PA, prognostic nutritional index (PNI) and LOS. Patients were divided into low PA group (n=42) and normal PA group (n=58) based on PA values. Body composition related indexes, PNI and LOS were compared between the two groups. The correlation between PA and each index was analyzed. The influencing factors of malnutrition were analyzed. The influencing factors of malnutrition were analyzed. Results Intracellular water, total body water, body cell content and PNI in the low PA group were significantly lower, and LOS was significantly longer than that in the normal PA group (P < 0.05). PA was positively correlated with intracellular water, extracellular water, total body water, skeletal muscle, body cell content, bone mineral content, basal metabolic rate and PNI (P < 0.05), while PA was negatively correlated with LOS (P < 0.05). PA (OR=5.441, P=0.001, 95%CI, 2.011 to 14.719) and LOS (OR=8.373, P < 0.001, 95%CI, 3.079 to 22.765) were the influential factors in the occurrence of malnutrition. Conclusion PA is significantly correlated with nutritional status and LOS in patients with severe craniocerebral injury.

BACKGROUND:It has been found that vascular endothelial growth factor 165 and bone morphogenetic proteins interact with each other during hypoxia-reoxygenation and are involved in the repair process of osteoblast injury by regulating the activation of intracellular signaling pathways. OBJECTIVE:To further investigate the relationship between vascular endothelial growth factor 165/bone morphogenetic protein and hypoxic-reoxygenated osteoblast injury. METHODS:Osteoblasts were selected and the hypoxic-reoxygenated injury model was established.Vascular endothelial growth factor 165 and bone morphogenetic protein expressions at mRNA and protein levels were detected by real-time PCR and western blot before and after modeling.After modeling,osteoblasts were given different concentrations of vascular endothelial growth factor 165 and bone morphogenetic protein 2(10,20,40 ng/mL).Cell proliferation was detected by cell counting kit-8 method and apoptosis was detected by DAPI at 12,24,36,48,and 72 hours after treatment. RESULTS AND CONCLUSION:Compared with before modeling,the mRNA and protein expressions of vascular endothelial growth factor 165 and bone morphogenetic protein 2 in osteoblasts after modeling were significantly decreased(P＜0.05).The proliferation rate of osteoblasts was significantly increased with the increase of vascular endothelial growth factor 165 concentration(P＜0.05),while the apoptosis rate of osteoblasts decreased significantly with the increase of vascular endothelial growth factor 165 concentration(P＜0.05).The proliferation rate of osteoblast was significantly increased with the increase of bone morphogenetic protein 2 concentration(P＜0.05),while the apoptosis rate of osteoblast decreased significantly with the increase of bone morphogenetic protein 2 concentration(P＜0.05).To conclude,vascular endothelial growth factor 165 and bone morphogenetic protein are lowly expressed in hypoxic-reoxygenated osteoblast injury,and treatment with vascular endothelial growth factor 165 and bone morphogenetic protein can reduce the injury of hypoxic-reoxygenated osteoblast in a concentration-dependent manner,suggesting that vascular endothelial growth factor 165 and bone morphogenetic protein have a significant protective effect against the injury of hypoxic-reoxygenated osteoblasts.

Objective:To explore the role of information-based points system management platform in enhancing the medical management capabilities of laboratory medicine.Methods:A total of 106 personnel who were on duty from January 2021 to December 2022 in the clinical laboratory of Guangdong Provincial People′s Hospital were selected and divided into 8 professional groups, including 24 in Clinical Routine Lab, 22 in Clinical Biochemistry Lab, 11 in Clinical Immune Lab, 13 in Clinical Microbiology Lab, 10 in Clinical Molecular Lab, 9 in Flow Cytometry Lab, 9 in HuiFu Lab, and 8 in Interdisciplinary Lab. Information-based points system management platform was established by formulating the detailed rules for the assessment of this points system, and the points achieved by the 106 participants in 2021 and 2022 were obtained and analyzed. The points were divided into 6 intervals (<41, 41-45, 46-50, 51-55, 56-60 and>60).Results:The overall medical points of laboratory medicine was significantly higher in 2022 than in 2021 (52.15±5.48 vs 49.81±3.73, P<0.001). In 2022, the number of participants with points between 41-45 and 46-50 intervals was lower than those in 2021; with points 51-55, 56-60 and>60 intervals was higher than those in 2021 (χ2=10.479, P<0.05). In addition, the points of Clinical Molecular, Clinical Microbiology and HuiFu Lab were 57.46±7.40, 52.05±5.43 and 54.98±4.31 respectively, which were significantly higher than those of 2021 (50.16±4.14, 49.10±4.06, 49.23±4.28, respectively;all P<0.05). The number of report revisions has significantly decreased in 2022 (18) compared to that in 2021 (48), clinical communication and various levels of publicity and promotion were significantly increased from 52 and 58 (2021) to 108 and 137 (2022), respectively. Conclusion:The construction and application of the information-based points management system have effectively improved the enthusiasm and subjective initiative of laboratory personnel, enhanced the quality and service capabilities of laboratory medicine, and might serve as an important tool for standardized management of laboratory medicine.

Objective:To construct and test the reliability and validity of an assessment scale for self-management of patients with dry eye, so as to help patients establish dry eye related health behaviors.Methods:Based on the knowledge attitude and practice theory, the initial scale was constructed on the basis of literature review and qualitative interview, and revised through Delphi expert consultation and expert argumentation. After the preliminary investigation, 211 dry eye patients treated in the dry eye nursing outpatient department of Beijing Tongren Hospital from August 2023 to January 2024 were selected by convenience sampling method for questionnaire investigation to test the reliability and validity of the scale.Results:Among 211 dry eye patients, there were 58 males and 153 females, aged (39.31 ± 12.81) years old. The scale of self-management of patients with dry eye included 27 items in 3 dimensions: knowledge, attitude and behavior. The authority coefficient of the two rounds of expert consultation was 0.86, and the Kendall coordination index increased from 0.175 to 0.223 (both P < 0.01). The cumulative variance contribution rates of the three dimensions were 41.843%, 54.219% and 44.273%, respectively. The Cronbach α coefficient of the scale was 0.787, and the Spearman-Brown coefficient was 0.641. Conclusions:The scale of self-management of patients with dry eye has good reliability and validity and can be used in the assessment of dry eye patients to provide a reference basis for targeted guidance and intervention.
