Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

OBJECTIVE To optimize the stir-frying process of Platycodon grandiflorum， compare the protective effect of P. grandiflorum on lung injury in mice before and after stir-frying， and preliminarily explore the characteristics of “enhanced efficacy through processing” of stir-frying P. grandiflorum. METHODS On the basis of single-factor experiment， the stir-frying time， temperature and frequency were taken as factors， and the comprehensive scores of appearance traits， platycodin D content and alcohol extract content were taken as indexes. Box-Behnken response surface experiment was designed to optimize the stir-frying process of P. grandiflorum and verify it. The mice were divided into blank control group， model group， dexamethasone group （positive control drug， 5 mg/kg）， P. grandiflorum low-dose and high-dose groups （0.6，1.2 g/kg）， fried P. grandiflorum low and high dose groups （0.6， 1.2 g/kg）， with 8 mice in each group. The treatment was given once a day for 10 consecutive days. After the last administration， acute lung injury model was established by intratracheal instillation of lipopolysaccharide. The levels of interleukin-6 （IL-6）， IL-1β， tumor necrosis factor-α （TNF-α） in serum and superoxide dismutase （SOD）， myeloperoxidase （MPO） and malondialdehyde （MDA） in lung tissue were detected， lung wet/dry weight ratio and thymus index were calculated， and the pathological changes of lung tissue were observed. RESULTS The optimum processing conditions were as follows：stir- frying temperature of 120 ℃， stir-frying time of 12 min， stir-frying frequency of 19 r/min； the comprehensive scores of the three batches of process verification were all greater than 97 points， RSD＜3% （n＝3）. The results of pharmacodynamic experiments showed that compared with blank control group， the lung dry-wet weight ratio as well as the levels of IL-6， IL-1β， TNF-α， MPO and MDA in the model group were significantly increased （P＜0.01）， the thymus index and SOD level were significantly decreased （P＜0.01）， and the lung tissue was significantly damaged. Compared with model group， above indexes of the mice in each administration group were significantly improved （P＜0.01）， and the lung tissue injury was significantly reduced. At the same dose， except for the lung dry-wet weight ratio， the above indexes of the mice in the stir-fried P. grandiflorum groups were significantly improved compared with P. grandiflorum 涵。E-mail：495758271@qq.com groups （P＜0.05）， and the lung tissue damage was further reduced. CONCLUSIONS The optimized stir-frying process is stable and feasible. The protective effect of stir-fried P.grandiflorum on acute lung injury in mice is better than that of raw products at the same dosage.

Neurofibromatosis type 1 (NF1) presents with a diverse range of symptoms that can affect the skin, bones, eyes, central nervous system, and other organs. This article reports the diagnosis and treatment process of a patient with NF1 complicated by bilateral severe-to-profound sensorineural hearing loss. Genetic testing revealed a heterozygous variant of NF1 NM_ 000267.3: c.4054_ 4058del(p.Ser1352LeufsTer20, supporting the diagnosis of NF1. After thorough evaluation, a right cochlear implantation was performed, yielding satisfactory postoperative results. This case suggests that NF1 patients may exhibit phenotypic heterogeneity and atypicality, providing a reference for clinicians in the diagnosis and treatment of such patients.

Objective: To explore the association between physical activity levels and depressive symptoms among college students, so as to provide evidence for promoting physical and mental health of college students. Methods: Using a cohort study design,a baseline survey of 1 415 college students in Shenyang Normal University in 2017 followed for three years from 2018 to 2020. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Selfrating Depression Scale (SDS) were used to evaluate the physical activity levels and depressive symptoms of college students. According to the level of physical activity at baseline (MET ·h/week), participants were divided into three groups [T1 (≤36.4), T2 (>36.4-89.3) and T3 (>89.3)]. Logistic regression analysis was used to examine the association between baseline physical activity levels and the incidence of depressive symptoms during the school years. Results: In the 3year followup (2018-2020), 852 (60.2%) participants exhibited depressive symptoms. The numbers of individuals with depressive symptoms in the T1, T2, and T3 groups were 324, 268, and 260, respectively. Logistic regression analysis showed that college students who participated in higher levels of physical activity decreased the risk of depressive symptoms by 34.2% [T2: OR(95%CI) = 0.658 (0.500-0.866)] and 38.9% [T3:OR(95%CI)=0.611(0.465-0.804)] compared with T1 group after adjusting for demographic, lifestyle, healthrelated factors, and baseline depressive symptoms as covariates. The sexstratified analysis showed a negative correlation between physical activity levels and the incidence of depressive symptoms in female college students. Compared with T1 group, higher levels of physical activity reduced the incidence of depressive symptoms by 39.6% [T2: OR(95%CI)=0.604(0.445-0.820)] and 37.7% [T3: OR(95%CI)=0.623(0.459-0.846)], respectively (P<0.01). However, there was no significant correlation between physical activity levels and depressive symptoms in male college students (P>0.05). Conclusions There is an inverse relationship between physical activity levels and depressive symptoms. The findings suggest that schools should reduce the risk of depressive symptoms by promoting physical activity levels among college students.

Objective To analyze the influencing factors of chronic obstructive pulmonary disease(COPD)complicating pulmonary interstitial fibrosis,and to establish a nomogram prediction model.Methods The clinical data of 195 patients with COPD admitted and treated in this hospital from January 2019 to Feb-ruary 2021 were retrospectively analyzed.The factors possibly affecting the patients with COPD complicating pulmonary interstitial fibrosis were collected,and the patients were divided into 2 groups according to whether having pulmonary interstitial fibrosis.The independent risk factors were analyzed and screened by the multi-variate logistic regression.Then the nomogram prediction model was constructed.Results Among the includ-ed 195 cases of COPD in this study,there were 50 cases(25.64％)of complicating pulmonary interstitial fi-brosis.The univariate and multivariate logistic regression analysis results showed that the smoking history,duration of COPD,frequency of acute exacerbations onset,serum transforming growth factor β1(TGF-β1),basic fibroblast growth factor(bFGF)and angiotensin Ⅱ(AngⅡ)were the independent influencing factors of COPD complicating pulmonary interstitial fibrosis(P＜0.05).The nomogram model was constructed accord-ing to the results of multivariate analysis results,and the area under the receiver operating characteristic(ROC)curve was 0.956(95％CI:0.930-0.983),the average absolute error of internal verification by the Bootstrap method was 0.025,and the prediction model performance basically fitted the ideal model.Conclusion The nomogram model constructed by this study for predicting the pulmonary interstitial fibrosis in COPD patients has high accuracy and distinction degree.

Objective:To observe the effects of warm acupuncture on post-stroke cognitive impairment (PSCI) based on the theory of intestinal flora.Methods:A randomized controlled trial was conducted. 60 patients with PSCI in the Department of Acupuncture and Neurology of the First Affiliated Hospital of Xinjiang Medical University from October 2020 to June 2022 were selected as the observation objects, and were divided into 2 groups by random number table, with 30 cases in each group. On the basis of cognitive rehabilitation training, the treatment group was given warm acupuncture treatment, and the control group was given routine acupuncture treatment. 2 groups were treated for 4 weeks as 1 course, and a total of 4 courses were treated. Montreal cognitive assessment (MoCA) was used to assess patients' cognitive function before and after treatment, and mini-mental state examination (MMSE) was used to assess patients' intelligence level. The numbers of bifidobacteria and lactic acid bacteria in fecal samples were calculated, and plasma gamma-aminobutyric acid (GABA) levels were detected by ELISA to evaluate the clinical efficacy.Results:During the study, 1 case was lost in each of the two groups, and finally 29 cases were included in the curative effect statistics. The total effective rate was 79.3% (23/29) in the treatment group and 65.5% (19/29) in the control group, with statistical significance ( χ2=43.39， P<0.05). After treatment, MoCA score [(24.23±1.36) vs. (21.26±1.30), t=3.12] and MMSE score [(25.35±1.24) vs. (21.52±1.22), t=3.25] in the treatment group were higher than those in the control group ( P<0.05); Bifidobacterium [(9.20±1.25) LgCFU/g vs. (7.23±1.21) LgCFU/g, t=2.98], Lactic acid bacteria [(8.24±1.12) LgCFU/g vs. (6.25±1.22) LgCFU/g, t=2.92], and the level of GABA [(283.80±83.54) mmol/L vs. (264.76±61.38) mmol/L, t=10.54] were higher than those in the control group ( P<0.05 or P<0.01). Conclusion:Warm acupuncture and moxibustion can effectively regulate the number of intestinal beneficial bacteria in PSCI patients, increase the level of GABA, promote brain tissue repair and improve cognitive function.

Conclusion:Utilizing the intra-prepontine cisternal drug infusion system to manage refractory craniofacial pain could provide advantages in terms of minimally invasive,secure,and effective treatment.This application can not only alleviate the suffering of individuals experiencing the prolonged pain but also support the maintenance of quality of life and dignity in their final moments,justifiing its widespread dissemination and standardized adoption in domestic and international professional fields.

Objective To clarify whether the use of dynamic coronary artery roadmap(DCR)technology in a low-dose mode with 7.5 frames per second during coronary intervention can further reduce the total radiation dose,fluoroscopy time,and contrast agent usage.Methods A total of 94 patients,who received coronary angiography at the Shanghai Tongji Hospital of China between July 2022 and December 2022,were enrolled in this study.The patients were randomly divided into DCR group(n=53)and control group(n=41).DCR technology was used in the DCR group to guide the performance of percutaneous coronary intervention(PCI),while low-dose mode coronary angiography was adopted in the control group.The total air kerma(AK),dose-area product(DAP),intraoperative fluoroscopy time,and contrast agent usage were compared between the two groups.Results In the DCR group AK was(597.9±222.8)mGy,which was significantly lower than(717.0±326.8)mGy in the control group(P=0.039);DAP was(33.2±13.3)Gycm2/s,which was also remarkably lower than(41.3±21.5)Gycm2/s in the control group(P=0.027).In the DCR group and the control group,the intraoperative fluoroscopy time was(9.8± 3.3)min and(12.1±4.3)min respectively(P＜0.01),and the contrast agent usage was(122.3±19.0)mL and(130.5± 28.5)mL respectively(P=0.116).Conclusion In a low-dose mode during coronary intervention,the use of DCR technology can further reduce radiation dose,fluoroscopy time,and contrast agent usage.(J Intervent Radiol,2024,33:236-239)

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

Objective: To study the association between 24 h activities and Fundamental Motor Skills (FMS) among children with autism spectrum disorder (ASD) using compositional data analysis, and the expected changes in FMS after isochronous substitution of each activity, in order to provide reference basis for improving FMS levels in children with ASD. Methods: From October 2023 to April 2024, a total of 301 children with ASD aged 6-10 from 7 special education schools in Jinan, were investigated by cluster random sampling, and 24 h movement behaviors were calculated based on accelerator data. Test of Gross Motor Development- 2 was used to assess FMS. R software was used to perform the descriptive statistical, multiple linear regression and isochronous substitution analyses. Results: The proportion of moderatevigorous physical activity (MVPA) in children with ASD was positively related with FMS scores, locomotor, and object control skills ( β=12.42, 6.32, 6.10, P <0.01). Reallocating 15 min from sleep (SLP) to MVPA resulted in respective increases of 3.66, 1.91, and 1.75 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from sedentary behavior (SB) to MVPA resulted in respective increases of 3.72, 1.88 , and 1.83 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from light physical activity (LPA) to MVPA resulted in respective increases of 3.32, 1.57, and 1.74 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Moreover, reallocating 15 min from SB to LPA resulted in an increase of 0.28 points in locomotor skills ( P <0.05). Dose response analysis revealed that substitution of MVPA for SLP, SB, and LPA in children with ASD enhanced their FMS levels, and their substitution was asymmetrical; and substitution of LPA for SB enhanced locomotor skills level. Conclusions Among the 24 h movement behaviors, increasing the time spent on MVPA and LPA have positive impacts on the FMS of children with ASD. Schools and families should optimize the allocation of 24 h activity time in children with ASD, so as to promote the improvement of FMS levels of children with ASD.
