Objective:To investigate the current status of fear of falling in postoperative cardiac surgery patients, and to analyze its influencing factors and interrelationships.Methods:A convenience sample of 246 postoperative cardiac surgery patients hospitalized in the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University, from December 2023 to December 2024 was surveyed. The Body Image Scale, the Personal Mastery Scale, the Fear of Falling Questionnaire-Revised, and a self-designed demographic and clinical questionnaire were used for data collection. Pearson correlation analysis was conducted to examine the relationships among body image, personal mastery, and fear of falling. PROCESS Model 4 was applied to test the mediating role of personal mastery between body image and fear of falling, with bootstrapping for verification.Results:A total of 246 questionnaires were distributed, and 236 valid responses were obtained (valid response rate: 95.93%) . The body image score was (14.02±6.36) , personal mastery score was (20.44±4.16) , and fear of falling score was (38.28±10.83) . Body image was positively correlated with fear of falling ( r=0.324, P<0.01) , while personal mastery was negatively correlated with fear of falling ( r=-0.552, P<0.01) . After controlling for variables with statistically significant differences in univariate analysis (including sex, age, education level, body mass index, history of syncope, pain level, and self-rated preoperative exercise capacity) , PROCESS analysis showed that body image had a direct positive effect on fear of falling ( β=0.288, P<0.05) , and also indirectly affected fear of falling through personal mastery, with the indirect effect accounting for 49.5% of the total effect (0.237/0.525) . Conclusions:Postoperative cardiac surgery patients require improvement in body image, personal mastery, and fear of falling. Understanding how body image influences fear of falling through personal mastery not only enriches theoretical frameworks but also provides guidance for psychological interventions in clinical practice, thereby meeting patients' psychological support needs during rehabilitation.

Objective To investigate the growth, development and health status of primary and secondary school students in Xinzhou District of Wuhan, and analyze the detection and change trend of common diseases in primary and secondary school students, and to provide a basis for relevant departments to formulate prevention and control measures of common diseases in students. Methods The monitoring data of common diseases and health influencing factors of primary and secondary school students in Xinzhou District from 2019 to 2022 were analyzed and compared according to different genders, different grades and ages. SPSS 20.0 software was used to analyze the data of detection rates of myopia, dental caries, obesity, malnutrition and abnormal spinal curvature. Results The overall detection rates of myopia, dental caries, malnutrition, obesity and abnormal spinal curvature were 57.00%, 58.45%, 4.60%, 14.91%, and 6.33%, respectively, in Xinzhou District from 2019 to 2022. The annual change rates were 7.22%, 15.10%, -2.72%, 13.29%, and 4.91%, respectively. The detection rates of myopia, dental caries, obesity and abnormal spinal curvature showed an increasing trend in each year (χ² ≥17.22, P<0.001). The detection rates of myopia and malnutrition increased with the increase of age and school level (both χ²≥42.37, P<0.001), while the opposite was true for the detection rates of dental caries and obesity (both χ²≥14.26, P<0.001). The detection rates of myopia and dental caries were higher in girls than in boys (both χ²≥33.66, P<0.001), while the detection rates of obesity and abnormal spinal curvature were higher in boys than in girls (both χ²≥8.22, P<0.005). The detection rates of myopia, dental caries, obesity and abnormal spinal curvature in 2019 were lower than those in 2020-2022 (χ²≥4.11, P<0.05), while the detection rates of malnutrition had decreased. Conclusion The growth, development and health status of primary and secondary school students in Xinzhou District are serious. The detection rate of common diseases such as myopia, dental caries, obesity and abnormal curvature of the spine is on the rise, which should be the focus of the surveillance work of common diseases in primary and secondary school students in the future, and comprehensive intervention measures are urgently needed to prevent and control these common diseases.

Objective:To observe the clinical efficacy of combined acupuncture and medication therapy in treating cerebral infarction in the acute stage and its impact on cerebral blood flow.Methods:A total of 160 patients with cerebral infarction were divided into 4 groups using the random number table method,with 40 cases in each group.Conventional treatment was given to all groups.Besides,the Chinese medication group received Tong Shen Fu Nao Wan;the acupuncture group received Xing Nao Kai Qiao(mind-refreshing and orifice-opening)needling therapy;the acupuncture-medication group received both Tong Shen Fu Nao Wan and Xing Nao Kai Qiao needling therapy.After 4 weeks of treatment,the clinical efficacy was assessed,and changes in the traditional Chinese medicine(TCM)symptom score and hemodynamics were compared among the four groups,as well as complications and adverse reactions.Results:After treatment,the acupuncture-medication group had a higher total effective rate compared to the other three groups(P<0.05).After the intervention,the National Institutes of Health stroke scale(NIHSS)score dropped in all groups(P<0.05)and was lower in the acupuncture-medication group than in the other three groups(P<0.05);all groups showed a decrease in the TCM symptom score(P<0.05),and the acupuncture-medication group was significantly lower than the other groups(P<0.05).After treatment,the blood flow velocity of the bilateral anterior cerebral artery(ACA),middle cerebral artery(MCA),and posterior cerebral artery(PCA)increased in every group(P<0.05),and the acupuncture-medication group had higher blood flow velocities compared to the other three groups(P<0.05).The acupuncture-medication group had the fewest number of complications among the four groups(P<0.05),and there was no statistical significance when comparing the adverse reactions among the groups(P>0.05).Conclusion:Compared to the separate use,the combined use of acupuncture and medication enhances the clinical efficacy,accelerates cerebral blood circulation,and boosts the recovery in treating cerebral infarction.

Objective:To compare and observe the fundus imaging characteristics of eyes with glucocorticoid-related central serous chorioretinopathy (CSC).Methods:A retrospective clinical study. A total of 149 CSC patients with 166 eyes diagnosed at Department of Ophthalmology of The First Affiliated Hospital of Zhengzhou University from March 2021 to October 2024 were included in the study. The duration of the disease from the appearance of symptoms to treatment was less than 3 months. All affected eyes underwent best-corrected visual acuity (BCVA), fundus color photography, swept-source optical coherence tomography (SS-OCT), and fundus fluorescein angiography (FFA) examinations. BCVA was tested using an international standard vision chart and converted into logarithm of the minimum angle of resolution (logMAR) visual acuity for statistical analysis. The SS-OCT instrument measured subfoveal choroidal thickness (SFCT), central macular thickness (CMT), choroidal vascular volume (CVV), and the width and height of flat irregular pigment epithelial detachment (FIPED). FIPED, subretinal fibrin, and choroidal layer strong reflective spots were identified from SS-OCTA B-scan images; multiple leakages (leak points >3) were identified from FFA images. Based on the presence or absence of a clear history of glucocorticoid administration before the onset, patients were divided into glucocorticoid-related and non-glucocorticoid-related groups, comprising 41 patients with 53 eyes and 108 patients with 113 eyes, respectively. Clinical and fundus imaging characteristics of the two groups were compared. The comparison of quantitative data between the two groups was performed using independent samples t test or non-parametric independent samples Wilcoxon test; the comparison of qualitative data was performed using χ2 test. Results:Compared with the non-glucocorticoid-related group, the glucocorticoid-related group had a smaller male-to-female ratio and a higher bilateral incidence, and the differences were statistically significant ( χ2=4.925, 17.849; P<0.05). The logMAR BCVA for the glucocorticoid-related and non-glucocorticoid-related groups were 0.45±0.33 and 0.21±0.21, respectively; SFCT were (644.43±131.91) and (507.26±121.79) μm; CMT were (389.51±233.45) and (362.59±140.85) μm; CVV were (4.44±1.07) and (3.67±0.82) mm 3; FIPED incidence were 58.49% (31/58) and 20.35% (23/113), respectively; FIPED width and height were (1 122.01±533.98) and (742.90±388.79) μm, and (99.13±92.17) and (33.01±15.99) μm; subretinal fibrin were observed in 24 (45.28%, 24/53) and 15 (13.27%, 15/113) eyes; choroidal strong reflections were found in 38 (71.70%, 38/53) and 45 (39.82%, 45/113) eyes; multiple leak points were identified in 35 (66.03%, 35/53) and 40 (35.40%, 40/113) eyes, respectively. Compared with the non-glucocorticoid-related group, the glucocorticoid-related group had worse BCVA ( Z=-4.984), thicker SFCT ( t=6.586), larger CVV ( t=5.160), higher incidence of FIPED ( χ2=23.908), and greater width and height of FIPED ( t=2.895, Z=-3.703). The glucocorticoid-related group also had a significantly increased incidence of subretinal fibrin, choroidal strong reflections, and multiple leak points, with all differences being statistically significant ( χ2=20.565, 14.663, 13.675; P<0.05); however, the comparison of CMT showed no statistically significant difference ( Z=-0.651, P>0.05). Conclusion:Compared with non-glucocorticoid-related CSC, glucocorticoid-related CSC patients have poorer vision, are more likely to affect both eyes, show no gender bias; choroidal vascular dilation is more significant, and damage to the outer retina and retinal pigment epithelium is more severe.

Objective:To explore the ventilation strategy of using pressure controlled ventilation-volume guaranteed (PCV-VG) mode combined with personalized positive end expiratory pressure (PEEP) during surgery, and its impact on oxygenation function and incidence of postoperative pulmonary complications (PPCs) in patients undergoing brain tumor surgery.Methods:Sixty patients who underwent elective brain tumor surgery at the Linyi People′s Hospital from January 2023 to June 2023 were selected. The patients were randomly divided into PCV-VG ventilation mode group (T group) and volume controlled ventilation (VCV) mode group (C group) using a random number table method, with 30 patients in each group. One patient was excluded from group T due to changes in the condition, and 29 patients were actually included. Group T adopted PCV-VG ventilation mode and searched for the maximum dynamic lung compliance (Cdyn) by titrating PEEP. The PEEP corresponding to the maximum Cdyn value was the optimal PEEP, which was maintained until the end of mechanical ventilation. Group C adopted a ventilation mode of VCV plus 5 cmH 2O fixed value PEEP. All patients underwent arterial blood gas analysis before anesthesia induction (T 1), 15 minutes after setting ventilation mode (T 2), and 15 minutes after extubation (T 3), recording arterial oxygen partial pressure (PaO 2), carbon dioxide partial pressure (PaCO 2), lactate (Lac), and blood glucose (Glu), and calculating oxygenation index (PaO 2/FiO 2). The levels of white blood cells (WBC), C-reactive protein (CRP), and procalcitonin (PCT) were recorded before and 72 hours after surgery. The incidence of postoperative PPCs at 72 hours was observed. Results:There was a statistically significant difference in the grouping effect and time effect of PaO 2 and PaCO 2 between group C and group T (all P<0.05), while there was no statistically significant difference in the interaction effect (all P>0.05); The differences in grouping effects, time effects, and interaction effects of PaO 2/FiO 2 between group C and group T were statistically significant (all P<0.05); The average value of the optimized PEEP obtained by T-group titration was 7.48 cmH 2O, corresponding to an average platform pressure (Pplat) of 14.90 cmH 2O, and an average value of 53.37 ml/cmH 2O corresponding to the maximum Cdyn value. Compared with the Pplat and Cdyn corresponding to the fixed value of 5 cmH 2O PEEP in Group C, the Pplat corresponding to the optimized PEEP in Group T was lower than that in Group C ( P<0.05), and the Cdyn was higher than that in group C ( P<0.05). The CRP level and incidence of PPCs in group T after 72 hours of surgery were significantly lower than those in group C (all P<0.05). Conclusions:Compared with VCV, the ventilation mode of PCV-VG combined with personalized PEEP can improve intraoperative lung ventilation and oxygenation function in patients with brain tumors, reduce the occurrence of pulmonary inflammation 72 hours after surgery, and lower the incidence of PPCs.

Objective To explore the clinical application of ultrasound-guided transabdominal villus and amniocentesis in the prenatal diagnosis of thalassemia,and to find a suitable method for the prenatal diagnosis of thalassemia in Qinzhou.Methods A total of 531 high-risk pregnant women with severe or intermediate thalassemia during single pregnancy who were treated in the Department of Medical Genetics and Prenatal Diagnosis,Qinzhou Maternal and Child Health Hospital from March 2021 to April 2022 were selected for the study.According to different sampling methods,they were divided into control group(amniocentesis,n=415)and study group(transabdominal villus puncture,n=116).The success rate,complication rate of the two groups were compared.Results The success rate of puncture in the control group was 100％,2 cases were aborted within 2 weeks after surgery,17 cases were diagnosed with severe alpha-thalassemia,10 cases with severe β-thalassemia and 64 cases with intermediate thalassemia,48 cases with moderate and severe thalassemia induced labor.The success rate of puncture in the research group was 100％,10 cases were diagnosed with severe alpha-thalassemia,4 cases with severe β-thalassemia and 17 cases with intermediate thalassemia,and 26 cases with moderate severe thalassemia were induced labor.There was no significant difference in puncture success rate and abortion rate between the two methods(P>0.05).Conclusion Both methods are safe and effective.Transabdominal villus sampling can detect fetal thalassemia in early pregnancy,and it is worth promoting and applying in clinical practice.

Objective:To observe the clinical characteristics and risk factors associated with pachydrusen in eyes affected by central serous chorioretinopathy (CSC).Methods:A retrospective clinical study. From July 2021 to June 2024, 144 cases and 158 eyes of CSC patients diagnosed through ophthalmological examination at Department of Ophthalmology of The First Affiliated Hospital of Zhengzhou University were included. All affected eyes underwent a series of assessments, including refraction, intraocular pressure measurement, fundus color photography, fluorescein fundus angiography (FFA), and swept-source optical coherence tomography (OCT). Additionally, 58 eyes underwent indocyanine green angiography (ICGA). Cross-sectional (en-face) OCT was utilized to observe the colocalization of pachydrusen with areas of dilation of large choroidal vessels and attenuation of the choriocapillaris layer. The device was used for OCT included software for calculating subfoveal choroidal thickness (SFCT). FFA fluorescein leakage was categorized into "ink stain", "cooking smoke", and "diffuse point leakage". Patients were classified into groups of CSC patients complicated by pachydrusen and groups of CSC patients without pachydrusen. Comparisons between the groups were performed using the χ2 test, and factors associated with the presence of pachydrusen were analyzed using logistic regression. Results:Among 158 eyes, 72 eyes (45.6%, 72/158) were complicated by pachydrusen. In en-face OCT images, pachydrusen were co-located with dilated large choroidal vessels in 59 eyes (81.94%, 59/72) and corresponded to choroidal capillary layer blood flow holes in 61 eyes (84.72%, 61/72). Among the 58 eyes that underwent ICGA examination, pachydrusen corresponded to punctate strong fluorescence in 46 eyes (79.31%, 46/58) and were located in areas of choroidal hyperpermeability in 43 eyes (74.14%, 43/58). Compared with the CSC group without pachydrusen, the incidence of choroidal neovascularization, flat irregular pigment epithelial detachment, diffuse punctal leakage and multiple leakage points increased in the CSC group, and the differences were statistically significant ( χ2=6.217, 8.455, 5.363, 17.749; P<0.05). Logistic regression analysis indicated that age [odds ratio ( OR)=1.116, 95% confidence interval ( CI) 1.060-1.176, P<0.001], chronic CSC [ OR=2.628, 95% CI 1.250-5.526, P=0.011] were independent risk factors for the occurrence of pachydrusen. Conclusions:The incidence of pachydrusen in eyes with CSC is 45.6%, with age and chronic CSC identified as independent risk factors for their occurrence. Pachydrusen correspond to dilated choroidal vessels and areas of choroidal hyperpermeability, which may serve as potential risk factors for CSC activity or development.
