Objective To develop a reminiscence therapy program with Montessori educational philosophy in treatment of elderly people with mild cognitive impairment(MCI)in nursing homes and evaluate its effect.Methods On the basis of Montessori education principles,a reminiscence therapy program was drafted through literature review and had it finalised with expert consultations and a pilot study.Between February and May 2022,70 elderly with MCI were recruited from a nursing home in Liaoning Province using convenience sampling.The recruited elderly were randomly divided into a control group(n=35)and an intervention group(n=35)using a random number table.The elderly in control group received conventional cognitive training only while the elderly in the intervention group received reminiscence therapy in addition to the conventional cognitive training.Cognitive function and ability of daily living(ADL)were compared between the two groups after a 6-week intervention.Results The elderly in intervention group demonstrated statistically significant improvements in both cognitive function and dimensions(visuospatial/executive function,naming ability,delayed recall and orientation,as well as in ADL after a 6-week intervention(all P<0.05).Conclusion The Montessori philosophy based on reminiscence therapy improves cognitive function and activities of daily living in the elderly with MCI,particularly from the perspectives of visuospatial/executive function,naming ability,delayed recall and orientation.

Objective:To analyze the efficacy and prognosis of surgical patients with traumatic epidural hematoma straddling the transverse sinus (TEHSTS).Methods:Clinical data of 4 360 patients with epidural hematoma admitted to the First Affiliated Hospital of Henan University of Science and Technology from January 2010 to April 2024 were collected. Among them, 109 cases (2.5%) were diagnosed with TEHSTS. Based on the rapid progression criteria for posterior fossa epidural hematoma [sudden deterioration of Glasgow Coma Scale (GCS) score within hours (a decrease of ≥1 point in the best motor response and/or a decrease of ≥2 points in GCS score), and progressive enlargement of TEHSTS on repeat CT scan], the timing and method of surgery were determined. Two surgical approaches were compared: combined supratentorial and infratentorial craniotomy (craniotomy group) and modified supratentorial burr-hole drainage (burr-hole group). Clinical data, surgical timing, surgical outcomes, and prognosis were compared between the two groups.Results:There were 57 cases (52.3%) in the craniotomy group and 52 cases (47.7%) in the modified burr-hole group. The proportion of patients presenting with vomiting upon admission was higher in the craniotomy group than in the burr-hole group [77.2%(44/57) vs 59.6%(31/52), P=0.048], and the proportion of patients with linear occipital fractures on CT was also higher in the craniotomy group [91.2%(52/57) vs 75.0%(39/52), P=0.023]. No significant differences were observed in other admission symptoms or CT findings between the two groups (all P>0.05). The GCS score upon admission was significantly lower in the craniotomy group [(11.0±1.0)points] than in the modified burr-hole group [(13.0±1.0)points] ( P<0.05). Four cases in the burr-hole group developed delayed hematomas, including two cases of bilateral delayed epidural hematomas. The preoperative GCS score in the craniotomy group [(9.0±0.5)points] was significantly lower than upon admission [(11.0±1.0)points] ( P<0.05), and the surgical timing was (6.5±1.5)hours after injury. The preoperative GCS score in the burr-hole group [(11.5±0.5)points] was also significantly lower than upon admission [(13.0±1.0)points] ( P<0.05), with surgical timing at (19.5±5.5)hours after injury. Preoperative CT scans showed no significant difference in hematoma volume between the burr-hole group [(35.5±7.5)ml] and the craniotomy group [(36.5±9.5)ml] ( P>0.05). The preoperative GCS score was significantly lower in the craniotomy group than in the burr-hole group ( P<0.05). The GCS scores at 24 hours postoperatively were significantly improved compared to preoperative scores in both groups (all P<0.05). The burr-hole group had significantly shorter operative time, less intraoperative blood loss, shorter intensive care unit (ICU) stay, and shorter hospital stay than the craniotomy group (all P<0.01). The incidence of postoperative pulmonary infection was lower in the burr-hole group than in the craniotomy group ( P<0.05). At 3-month follow-up, the rate of good recovery [Glasgow Outcome Scale (GOS) score≥4 points] was significantly higher in the burr-hole group (98.1%) than in the craniotomy group (93.0%) ( P<0.01). Conclusions:TEHSTS should be managed with different surgical approaches based on admission symptoms, GCS score, and the speed of disease progression. The modified burr-hole drainage procedure is convenient, safe, and associated with better prognosis.

Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Objective Based on sentinel symptoms,a nursing intervention program for gastrointestinal symptom group of postoperative chemotherapy for lung cancer was constructed and its application effect was evaluated.Methods The nursing intervention program of gastrointestinal symptom group was constructed on the basis of ref-erence guidelines,qualitative interview and expert consultation.From January 2021 to January 2022,a total of 330 patients with postoperative chemotherapy for lung cancer in a tertiary hospital in Shenyang were selected as re-search subjects.The experimental group received the gastrointestinal symptoms group nursing intervention program on the basis of routine nursing,and the control group received routine care.Patients were investigated with the M.D.Anderson Symptom Inventory and the MOS 36-Item Short-Form Health Survey before 1st chemotherapy(T1),3rd chemotherapy(T2)and 5th chemotherapy(T3).Results After the intervention,the total scores of the 2 groups and the total scores of each symptom in T2 and T3 were statistically significant(P＜0.05),and the score of the experi-mental group was lower than that of the control group.For the scores of 6 dimensions of physiological function,physical pain,overall health,vitality,emotional function,mental health in 2 groups between different time points,the differences are statistically significant(P＜0.05).Conclusion The nursing intervention program of the gastroin-testinal symptom group based on sentinel symptoms is beneficial to reduce the severity of the gastrointestinal symp-tom group and improve the quality of life for postoperative chemotherapy for lung cancer patients.

Background The compound 6:2 chlorinated polyfluorinated ether sulfonic acids (6:2 Cl-PFESA) has been demonstrated abilities of strong bioaccumulation and placental barrier penetration, and it can also cross the blood-brain barrier. However, the mechanism of its neurodevelopmental toxicity in offspring induced by early-life exposure is still unknown. Objective To explore effects of 6:2 Cl-PFESA on the growth and the α-amino-3-hydroxy-5-methylisoxazole-4-propionic (AMPA) receptor gene expression in the hippocampus of offspring mice by establishing a 6:2 Cl-PFESA exposure animal model. Methods Thirty Kunming pregnant mice were randomly divided into five groups: control group, and 2, 10, 50, and 250 μg·L⁻¹ 6:2 Cl-PFESA exposure groups. The treatment groups were exposed to designed doses of 6:2 Cl-PFESA through drinking water from the first day of gestation until the end of lactation. The pups were weaned on postnatal day (PND) 21, and continued to be exposed to 6:2 Cl-PFESA through drinking water. Birth weight and body length of the offspring were recorded. Offspring mice were anesthetized and sacrificed respectively on PND7, PND21, and PND35, then their hippocampus was peeled from harvested brain tissue. The ultrastructure of hippocampus was observed via transmission electron microscopy; and the expression of AMPA receptors GluR1, GluR2, and GluR3 in the hippocampus was evaluated by real-time reverse transcription polymerase chain reaction. The learning and memory ability of the PND35 mice was measured by Morris water maze test before they were sacrificed. Results The birth weights and the lengths of the pups in the 10, 50, and 250 μg·L⁻¹ 6:2 Cl-PFESA exposure groups were (2.23±0.36), (1.92±0.20), (1.88±0.31) g, and (33.73±0.98), (32.91±1.30), (32.52±2.07) mm, respectively, which were lower than those in the control group, (2.78±0.35) g and (36.46±2.34) mm (P<0.05), respectively. The results of Morris water maze showed that the escape latencies in the orientation navigation experiment on the 4th day in the 250 μg·L⁻¹ 6:2 Cl-PFESA exposure group and on the 5th day in the 10, 50, and 250 μg·L⁻¹ 6:2 Cl-PFESA exposure groups were longer than those in the control group (P<0.05). In the space exploration experiment, the times of crossing platform in the 50 and 250 μg·L⁻¹ 6:2 Cl-PFESA exposure groups were decreased when compared with the control group (P<0.05), and the time of staying in the target quadrant of the 250 μg·L⁻¹ 6:2 Cl-PFESA exposure groups were also decreased (P<0.05). Via transmission electron microscopy, compared with the control group, the postsynaptic density was decreased and the synaptic cleft width was widened on PND35 in the 250 μg·L⁻¹ 6:2 Cl-PFESA exposure group. The mRNA expression levels of GluR1, GluR2, and GluR3 in the hippocampus of pups exposed to 250 μg·L⁻¹ 6:2 Cl-PFESA during different developmental stages were significantly lower than those in the control group (P<0.05). Except for the 2 μg·L⁻¹ 6:2 Cl-PFESA exposure group on PND7, the 6:2 Cl-PFESA exposure inhibited the mRNA expression levels of GluR1, GluR2, and GluR3 in the hippocampus of pups at different developmental stages (P<0.05). Among them, the 6:2 Cl-PFESA exposure during early development resulted in the highest decrease in the expression levels of GluR1 and GluR2 mRNA in the hippocampus of pups on PND7; GluR3 mRNA expression level in the hippocampus of the exposed pups on PND21 showed the maximum inhibitory effect; the expression levels of GluR1, GluR2, and GluR3 mRNA all showed the least decrease in the hippocampus of the exposure groups on PND35. Conclusion Early-life exposure to 6:2 Cl-PFESA may affect the growth and development of offspring mice, alter the hippocampal synaptic structure, and influence the learning and memory abilities, which may be related to their inhibitory effects on the expression levels of AMPA receptor subunits GluR1, GluR2, and GluR3 genes in the hippocampus of offspring mice at various developmental stages.

Objective:To evaluate the safety and effectiveness of dual-plane breast augmentation via endoscopic assisted axillary approach.Methods:A retrospective analysis was conducted on 215 female patients who underwent dual-plane breast augmentation via endoscopic assisted axillary approach from March 2019 to March 2021 (15 cases at Longhua Maternal and Child Health Hospital and 200 cases at Chongqing Huamei Hospital). The patient′s age was 22-45 (32.32±5.67) years. 42 cases underwent dual-plane breast augmentation via endoscopic assisted axillary approach, by using a combination of blunt and sharp methods to separate the cavity; while 173 cases used sharp methods to separate cavities. The complications related to breast augmentation were evaluated during a follow-up period of 6 to 18 months.Results:None of the 215 patients experienced wound infection, postoperative hematoma formation, or skin burns. The long-term complications included 1 case (0.46%) of grade Ⅰ capsule contracture, 1 case (0.46%) of grade Ⅲ capsule contracture, and 12 cases (5.58%) of nipple areola sensory impairment or reduction. A patient with grade Ⅲ capsule contracture underwent right capsulotomy and replacement of the prosthesis.Conclusions:The endoscope-assisted transaxillary dual-plane breast augmentation surgery has higher safety and satisfactory, worthy of clinical promotion and application.

Objective:To explore effects of health education based on teach-back method on functional exercise compliance in patients with kinesophobia after total knee arthroplasty (TKA) .Methods:Using the convenient sampling method, a total of 104 patients with TKA kinesiophobia who were admitted to First Ward of Department of Orthopedics in the First Affiliated Hospital of Zhengzhou University from August 2019 to November 2020 were selected as the research objects. Among them, 52 patients admitted from August 2019 to March 2020 were set as the control group, while 52 patients admitted from April to November 2020 were set as the experimental group. They were respectively given routine health education and health education based on teach-back method. Before the intervention and 2 weeks after the intervention, the differences in Functional Exercise Compliance Scale for Orthopedic Patients, Hospital for Special Surgery Knee Score (HSS) and Modified Barthel Index (MBI) scores were compared between the two groups.Results:After implementing the health education intervention program based on the teach-back method, the total score of Functional Exercise Compliance Scale for Orthopedic Patients of patients and dimensions scores of exercise compliance related to physical aspects, the exercise compliance related to psychological aspects and the exercise compliance related to active learning in the experimental group were higher than those of the control group, and the differences were statistically significant ( P<0.05) .
