To develop a portable transport vehicle for single injured soldier in field warfare,so as to meet the target of completing emergency transshipment for single injured solider in both peacetime and wartime.The main body of the transport vehicle consists of a general stretcher and an additional wheel device.The stretcher provides a supporting platform for lying down and prone position of injured solider.The device of additional wheel is a foldable portable structure with two-wheels,which composed of 2 wheels,2 sets of frames,a crossbeam,connecting rods,buckles,and hooks.When transport task for injured solider needs to be performed,it can be connected to the stretcher to be expanded as a stretcher cart for transporting injured solider.In normal times,it can be folded for storage in a backpack.The use of the portable transport vehicle for single injured soldier in field warfare can reduce the number of personnel who carries out the stretcher from 2-3 person to 1 person,and can significantly reduce the frequency of transport,and shorten the overall time of transport,and remarkably improve efficiency of transport.Moreover,the scores of medical members for the performance of labor-saving and the recommendation level of transport vehicle in this study were higher than general stretcher,and the differences were significant(t=9.52,3.60,P<0.05).This transport vehicle has a reasonably structural design,favorable portability and safety.It can greatly improve the efficiency of transporting injured solider under limited conditions,and enhance the possibility that successfully rescue injured solider,and meet the requirement of grass-roots unit of army for practical combat in transporting injured solider,which is a suitable transport tool.

Objective To investigate the immediate therapeutic efficacy of Kuanxiong Aerosol on improving the angina pectoris in the patients complicated with intermediate coronary stenosis(ICS),and to observe its effect on resting full-cycle ratio(RFR),corrected TIMI(thrombolysis in myocardial infarction)frame count(CTFC)in angiography,and coronary serum inflammatory factors.Methods Sixty angina pectoris patients with ICS admitted to the Cardiovascular Department of Dade Road Hospital,Guangdong Provincial Hospital of Traditional Chinese Medicine from March 2023 to March 2024 were randomly divided into the trial group and the control group,with 30 patients in each group.The trial group was given four consecutive sprays of Kuanxiong Aerosol by sublingual spray,and the control group had no intervention but just was given the monitoring for 10 minutes.Before and after the intervention,the changes of coronary RFR,CTFC,Visual Analogue Scale(VAS)score of chest pain,and the serum levels of C-reactive protein(CRP),interleukin 6(IL-6)and lipoprotein-associated phospholipase A2(Lp-PLA2)in the two groups were observed.Moreover,the incidence of adverse reactions during the intervention in the two groups of patients was compared.Results(1)After the intervention,the coronary RFR value of the trial group was increased significantly compared with that before intervention(P<0.01),while the coronary RFR value of the control group was not increased significantly compared with that before intervention(P>0.05);the comparison between the two groups showed that the effect on increasing the coronary RFR value in the trial group was superior to that in the control group(P<0.05).(2)After intervention,the CTFC value of the trial group was significantly decreased compared with that before intervention(P<0.01),while the CTFC value of the control group was not significantly decreased compared with that before intervention(P>0.05);the intergroup comparison showed that the trial group tended to have a better effect on the decrease of CTFC value than the control group,but the difference being not statistically significant(P>0.05).(3)After the intervention,the chest pain VAS score of the trial group was significantly reduced compared with that before intervention(P<0.01),while the pre-and post-treatment changes of the score in the control group was not significant(P>0.05);the intergroup comparison showed that the decrease of the chest pain VAS score in the trial group was superior to that in the control group(P<0.01).In particular for immediate therapeutic efficacy,Kuanxiong Aerosol achieved the effective rate of 96.67%(29/30)for relieving chest pain 10 minutes after sublingual spraying,which was significantly superior to that of the control group[10.00%(3/30)],and the comparison between the two groups showed that the difference was statistically significant(P<0.001).(4)After the intervention,the Lp-LPA2 value of the trial group was decreased compared with that before intervention(P<0.05),while the CRP and IL-6 values of the trial group as well as the CRP,IL-6,and Lp-LPA2 values of the control group were all not significantly decreased compared with those before intervention(P>0.05).The intergroup comparison showed that the trial group's effect on the decrease of Lp-LPA2 value was significantly superior to that of the control group(P<0.05).(5)Before and after the intervention,no obvious changes of the general vital signs in the two groups were shown,no drug-related adverse occurred,either.Conclusion Kuanxiong Aerosol can immediately improve the coronary physiological function indicators of angina pectoris patients with ICS,increase the coronary flow rate,and inhibit inflammatory response of the coronary artery to some degree,thus to alleviate the symptoms of angina pectoris in patients with ICS.

Objective: To construct a prediction model for sleep disorders in shift workers of a chemical fiber enterprise, so as to provide the basis for early identification and prevention of sleep disorders in shift workers. Methods: Shift workers were sampled from a chemical fiber enterprise in Tongxiang City, Zhejiang Province using a cluster sampling method from August 2022 to July 2024. Demographic information, length of service and average weekly working hours were collected through questionnaire surveys. Depressive symptoms, anxiety symptoms and sleep disorders were evaluated using the Pittsburgh Sleep Quality Index, Patient Health Questionnaire and Generalized Anxiety Disorder Questionnaire, respectively. The shift workers were randomly divided into a training set and a validation set at a ratio of 7∶3. Predictive factors were selected using a multivariable logistic regression model based on the training set, and a nomograph model for prediction of sleep disorders in shift workers was established. The predictive values of the model were evaluated using the receiver operating characteristic (ROC) curve and calibration curve based on the training set and validation set. Results: Totally 673 shift workers were included, with a median age of 32 (interquartile range, 12) years. There were 493 males, accounting for 73.25%. There were 471 (69.99%) workers in the training set and 202 (30.01%) workers in the validation set. There were 274 workers with sleep disorders, accounting for 40.71%. The equation for the prediction model was ln[p/(1-p)]=-8.391+1.906×average weekly working hours+1.822×depressive symptoms+1.667×anxiety symptoms. The area under the ROC curve was 0.769 (95%CI: 0.661-0.835) for the training set and 0.655 (95%CI: 0.593-0.737) for the validation set, and Hosmer-Lemeshow test showed a good fitting effect (both P>0.05). Conclusion The nomograph model constructed by average weekly working hours, depressive symptoms and anxiety symptoms can be used to predict the risk of sleep disorders in shift workers of a chemical fiber enterprise.

Objective:To explore the effects of real-time feedback intervention based on ecological momentary assessment on health behaviors and quality of life in stroke patients, to provide new insights and evidence for secondary prevention of stroke and post-discharge rehabilitation management.Methods:This was a non synchronous controlled study. A total of 160 stroke patients admitted to the First Affiliated Hospital of Soochow University from January 2022 to June 2023 were selected by convenience sampling method and sequentially assigned to a control group (80 cases) and an intervention group (80 cases) according to the admission time. The control group received routine discharge follow-ups. The intervention group wore smart wristbands and received ecological momentary assessment -based real-time feedback intervention. Health behaviors and quality of life were compared between the two groups before discharge, 3 months and 6 months after discharge.Results:Both groups of patients completed the study. In the intervention group, there were 43 cases aged ≤ 65 years and 37 cases aged>65 years, with 55 males and 25 females. In the control group, there were 42 cases aged ≤ 65 years and 38 cases aged>65 years, with 53 males and 27 females. There were no significant differences in the level of health behaviors and quality of life before discharge between the two groups (both P>0.05). At both 3 and 6 months after discharge, the total scores of the health behaviors were (92.59 ± 7.12), (92.58 ± 5.77) points in the intervention group, and (86.15 ± 14.64), (83.40 ± 8.19) points in the control group, there were significant differences between the two groups ( t=-3.54, -7.72; both P<0.01). The quality of life in the intervention group at 3 months after discharge was 0.904 ± 0.123, which was higher than the control group's 0.845 ± 0.232, and the difference was statistically significant ( t=-2.01, P<0.05). However, there was no statistically significant difference in the quality of life between the two groups at 6 months after discharge ( P>0.05). The overall compliance rate with smart wristband usage in the intervention group was 100%(80/80). Conclusions:Ecological momentary assessment-based real-time feedback intervention effectively improves health behaviors in stroke patients and enhances their quality of life in the short term, demonstrating good feasibility and acceptability.

Objective To investigate the relationships of serum levels of human fractalkine (CX3CL1) and chitinase-3-like protein 1 (YKL-40) with early cognitive impairment in elderly patients with Alzheimer's disease (AD). Methods A total of 110 AD patients in the Second Affiliated Hospital of Xinxiang Medical University from February 2021 to December 2023 were selected as AD group, and 50 healthy individuals with physical examination during the same period were selected as control group. Clinical materials and serum levels of CX3CL1 and YKL-40 were compared between the two groups, and multivariate Logistic regression models were used to analyze the influencing factors of cognitive impairment in AD patients. Based on the Mini-Mental State Examination (MMSE) score, the 110 AD patients were divided into mild cognitive impairment group (n=47), moderate cognitive impairment group (n=36), and severe cognitive impairment group (n=27). Spearman correlation analysis was performed to explore the relationships of serum CX3CL1 and YKL-40 with MMSE score, Addenbrooke's Cognitive Examination-Ⅲ (ACE-Ⅲ) score, and Montreal Cognitive Assessment (MoCA) score. Results The AD group had higher proportions of patients aged over 80 years, with an education level of primary school or below, smoking history, alcohol consumption history, diabetes mellitus, hypertension, AD family history, and living alone as well as higher serum levels of CX3CL1 and YKL-40 compared to the control group; conversely, the AD group had a lower proportion of patients engaging in no physical exercise/labor, and lower MMSE, ACE-Ⅲ, and MoCA scores, with significant between-group differences (P < 0.05). Advanced age, diabetes mellitus, and high serum levels of CX3CL1 and YKL-40 were independent risk factors for cognitive impairment in AD patients (P < 0.05), while an education level of college or above was a protective factor (P < 0.05). Compared with the mild cognitive impairment group, the moderate and severe cognitive impairment groups had higher serum levels of CX3CL1 and YKL-40, and the severe cognitive impairment group had higher serum levels of CX3CL1 and YKL-40 than the moderate group, with significant between-group differences (P < 0.05). Spearman correlation analysis revealed that serum CX3CL1 and YKL-40 were negatively correlated with MMSE, ACE-Ⅲ, and MoCA scores (P < 0.05). Conclusion Serum CX3CL1 and YKL-40 are highly expressed in elderly AD patients, and are closely related to early cognitive impairment in elderly AD patients.

Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d⁻¹ increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹ were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week⁻¹ group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week⁻¹ group compared to the <1 serving·week⁻¹ SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (P_interaction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L⁻¹ and 0.18 mmol·L⁻¹, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.
