Objective: To investigate the relationship between 24 hour activity behaviors and fine motor development in preschool children, and to simulate the effects of reallocating time among different activity behaviors on fine motor development using isotemporal substitution analysis. Methods: From March to July 2022, a stratified cluster random sampling method was used to recruit 447 preschool children aged 3-6 years (254 boys and 193 girls) from Pingxiang City, Jiangxi Province. The 24 hour activity behaviors in preschool children were measured using ActiGraph wGT3-BT accelerometers and subjective sleep reports. Fine motor development was assessed using the Gesell Developmental Schedules. A component linear regression model was employed to analyze the impact of 24 hour activity behaviors on the development of fine motor activities, and the potential effects of adjusting activity behaviors were simulated through an isochoric substitution model. Results: The daily durations of sedentary behavior (SB) was ( 572.92 ±102.96) min (accounting for 39.79% of 24 h), the duration of light physical activity (LPA) was (131.21± 38.11 ) min ( 9.11% ), the duration of moderate to vigorous physical activity (MVPA) was (65.61±22.21) min (4.56%), and sleep duration was (670.65±57.58) min (46.82%). Sleep composition was positively associated with fine motor development ( β =2.74), while MVPA ( β =-0.84) and SB ( β =-1.93) compositions were negatively associated with fine motor development (all P <0.01). Isochoric substitution analysis showed that sleep had positive effects on the development of fine motor skills when replacing other activity behaviors (all P < 0.05), with the substitution effect for MVPA being the most significant and gradually increasing with the duration of substitution (60 min: β =28.66); sleep replacement of SB and LPA also showed positive effects (60 min: β =4.25, 2.00) (all P < 0.05). On the contrary, the substitution of sleep with MVPA showed negative effects (60 min: β =-7.86), and the substitution of LPA and SB with MVPA also showed negative effects (60 min: β =-5.65, -3.40) (all P <0.05). Conclusions The overall composition of 24 hour activity behaviors is associated with fine motor development in preschool children, with sleep playing a crucial role. Ensuring adequate sleep and optimizing the structure of activity behaviors may effectively promote the development of fine motor skills in preschool children.

Objective To investigate the effect of deoxyelephantopin(Deo)on regulation of cell apoptosis pathway by reactive oxygen species(ROS)in human non-small cell lung cancer A549 cells.Methods A549 cells were treated with different concentrations of Deo.Cell counting kit 8(CCK-8)assay was used to detect the cell viability,2',7'-dichlorodihydrofluorescein diacetate(DCFH-DA)staining was used to measure cellular ROS content,and Hoechst 33342 staining was used to detect apoptotic bodies.Cell apoptosis and mitochondrial membrane potential were examined by flow cytometry.Quantitative polymerase chain reaction and Western blotting were used to detect the expression of apoptosis-related proteins.A549 xenograft tumor model in nude mice was used to evaluate the anti-tumor effect of Deo in vivo.Hematoxylin-eosin staining and TUNEL assay were used to observe the necrosis and cell apoptosis in tumor tissues.Results With the increase of Deo concentration(1,2,4,8,16,32 μmol/L),the viability of A549 cells showed a decreasing trend.Deo at 10 μmol/L could increase the ROS content in A549 cells,reduce mitochondrial membrane potential and promote cell apoptosis.Deo at 10 and 20 μmol/L promoted the mRNA and protein expression of Bax and caspase-3 and inhibited the mRNA and protein expression of Bcl-2,accompanied by significantly increased protein expression of cytochrome C in the cytoplasm.The volume and weight of transplanted tumor in nude mice were significantly inhibited after 17 d of administration of Deo of 10 and 20 mg·kg-1·d-1,and the necrotic area and the number of apoptotic cells in the tumor tissue were increased.Conclusion Deo can induce intracellular ROS production,and then activate the mitochondrial apoptosis pathway and consequently promote the apoptosis of A549 cells.

Objective:To investigate the iodine nutrition status of children aged 8 - 10 and pregnant women in Xining City, Qinghai Province.Methods:From 2019 to 2021, a stratified cluster sampling method was used to divide 7 counties (districts) under the jurisdiction of Xining City, Qinghai Province into 5 sampling areas according to east, west, south, north, and center each year. One township (town, street) was selected from each area. Forty non boarding students aged 8 to 10 from each primary school (half male and half female, age balanced) and 20 pregnant women from each township (town, street) location were selected to collect edible salt samples at home and a random urine sample to measure salt iodine and urinary iodine level. B-ultrasound was used to measure thyroid volume in children and the goiter rate was calculated.Results:A total of 6 534 samples of household edible salt were collected from children and pregnant women, with an average salt iodine concentration of 25.58 mg/kg. The coverage rate of iodized salt was 97.50% (6 371/6 534), and the qualified iodized salt consumption rate was 89.46% (5 845/6 534). A total of 4 362 urine samples were collected from children, with a median urinary iodine level of 183.10 μg/L. The difference between different years was statistically significant ( H = 20.27, P < 0.001). A total of 2 169 urine samples were collected from pregnant women, with a median urinary iodine level of 168.90 μg/L. The difference between different years was statistically significant ( H = 107.09, P < 0.001). A total of 3 336 cases of thyroid gland examination were conducted in children, including 33 cases of thyroid enlargement, with a goiter rate of 0.99%. There was a statistically significant difference between different years (χ 2 = 15.00, P < 0.001). Conclusion:From 2019 to 2021, children aged 8 to 10 and pregnant women in Xining City are at an appropriate level of iodine, and the achievements in prevention and treatment of iodine deficiency disorders still need to be continuously consolidated.

Objective:To evaluate the clinical efficacy and safety of sacubitril/valsartan in the treatment of hypertension complicated with heart failure.Methods:This retrospective study included 159 patients with hypertension and heart failure who were admitted to our hospital from Jan 2022 to Sep 2023 and treated with sacubitril/valsartan.Based on whether the treatment was discontinued,the patients were divided into the discontinuation group(58 cases)and the non-discontinuation group(101 cases).The baseline characteristics of the two groups were compared,and changes in blood pressure,cardiac ultrasound parameters,and serum biomarkers before and after treatment were analyzed in 101 patients undergoing continuous treatment.Results:There were no significant differences in baseline characteristics between the two groups(P＞0.05).After 12 months of continuous treatment,systolic and diastolic blood pressure significantly decreased(P＜0.01),left atrial diameter,left ventricular end-systolic diameter,and left ventricular end-diastolic diameter were significantly reduced,left ventricular ejection fraction significantly improved(P＜0.01),and NT-proBNP level significantly decreased(P＜0.01).In the discontinuation group,65.5%of patients discontinued treatment due to adverse reactions,mainly including renal function deterioration(24.1%),hypotension(20.7%),and hyperkalemia(10.3%).The readmission rate in the discontinuation group was higher than that in the non-discontinuation group(P＜0.05).Conclusions:Sacubitril/valsartan effectively improves blood pressure control and cardiac function in patients with hypertension combined with heart failure.However,the risk of adverse reactions in specific high-risk populations warrants close monitoring in clinical practice.

Objective:To explore the application effect of risk anticipation and coping intervention model in patients with cervical spondylosis undergoing anterior decompression and bone grafting with internal fixation.Methods:A convenience sampling method was used to select 132 patients with cervical spondylosis who underwent the aforementioned surgical procedure at the First Affiliated Hospital of Anhui Medical University between January 2022 and June 2024. Patients admitted between January 2022 and March 2023 ( n=66) formed the control group and received routine nursing care, while those admitted between April 2023 and June 2024 ( n=66) formed the observation group and received nursing interventions based on the risk anticipation and coping model. Both groups were followed until three months after discharge. Pain intensity, swallowing function, nutritional status, cervical spine function, and quality of life were compared between the two groups. Results:Pain scores were lower in the observation group than in the control group at 6, 12, 24, and 48 hours postoperatively ( P<0.05) . At 24 and 48 hours postoperatively, the observation group had significantly better scores on the Kubota Water Swallowing Test compared to the control group ( P<0.05) . On the day before discharge and three months post-discharge, body mass index, plasma albumin, total protein, Japanese Orthopaedic Association score, and quality of life score were all significantly higher in the observation group than in the control group ( P<0.05) . Conclusions:The risk anticipation and coping intervention model can effectively reduce postoperative pain and improve swallowing function in patients undergoing anterior decompression and bone grafting with internal fixation for cervical spondylosis. It also promotes the recovery of cervical spine function and enhances quality of life.
