BACKGROUND: The abnormal gait of stroke patients seriously affects their propulsive force during walking, which subsequently reduces their walking speed, walking distance, and stability, increases their risk of falls, and seriously affects their quality of life. OBJECTIVE: To review the relevant research on propulsive force deficits in stroke patients with hemiplegia, to summarize the understanding of existing researchers on propulsive force deficits, to analyze the relationship between propulsive force and gait, and finally to explain and compare the latest rehabilitation technologies used to improve propulsive force deficits, providing reference for clinical treatment. METHODS: Relevant literature was retrieved from WanFang, CNKI, PubMed, and Web of Science Core Collection through computer search. The Chinese and English search terms were “propulsive force OR propulsive, stroke OR cerebral infarction OR hemiplegia, walk* OR gait.” The search time limit was from 2003 to 2023, and 71 articles were finally included for review and analysis. RESULTS AND CONCLUSION: Training targeting the hip and ankle joints may be more effective for patients’ walking function, especially training with the application of flexible exoskeleton robots, but more sufficient evidence is still needed to use propulsion as a prognostic indicator of walking function in stroke patients. Biomechanical variables related to propulsive force include: the hip joint extension angle at terminal stance, ankle joint dorsiflexion torque, and knee joint extension. Damage to the corticospinal tract, cerebellar-cortical pathways, and the reticulospinal tract in hemiplegic patients are associated with reduced propulsive force and gait asymmetry. Propulsive force is crucial for the stability of healthy gait, and a decrease in propulsive force is unfavorable for gait stability. Gait symmetry is correlated with propulsive force, stride length symmetry, trunk displacement, and lower limb swing ability, with propulsive force being a key factor. Propulsive force can serve as a quantitative indicator for assessing the gait of hemiplegic patients, and evaluation of gait using propulsive force is beneficial for the long-term development of walking ability. Main rehabilitation techniques for improving propulsive force include: lower limb exoskeleton robot walking training, treadmill training combined with functional electrical stimulation, adaptive speed treadmill training, biofeedback technology, and whole-body vibration training. Among them, whole-body vibration training and biofeedback technology are more effective. The specific contributions and mechanisms of the hip, knee, and ankle joints in improving propulsive force are still controversial, but it is expected that the contributions of the hip and ankle joints are greater. Focusing on the improvement of propulsive force as a rehabilitation goal may yield more sustainable advancements in walking function. However, several current challenges persist in this field: understanding the neurobiological basis of propulsive force deficits in stroke patients, assessing the long-term efficacy of current rehabilitation techniques for enhancing propulsive force, and determining the most suitable patient populations for the application of major rehabilitation techniques aiming at improving propulsive force. These areas require further exploration by subsequent researchers. [ABSTRACT FROM AUTHOR]

Ferroptosis is an iron-dependent form of regulated cell death, which is distinct from apoptosis, necrosis, and pyroptosis. Recent studies have found that activators of ferroptosis, such as Erastin, can activate autophagy-related proteins, induce the formation of autophagosomes, and ultimately release ferric ions to mediate ferroptosis. This process, called ferritinophagy, is initiated by the binding of an autophagic cargo receptor protein, nuclear receptor coactivator 4（NCOA4）, to iron-laden ferritin. The transfer of NCOA4-ferritin to the lysosome by ferritinophagy results in the proteolysis of ferritin, and, in turn, the release of its iron content and lipid-reactive oxygen species (ROS) accumulation. Ferritinophagy has been closely associated with central nervous system disorders, circulatory system diseases, and cancer. Furthermore, the regulation mechanism of ferritinophagy is also a hot topic in the study of iron-dependent cell death process. With the in-depth study of ferritinophagy, great progress has been made in the study of key components of ferritinophagy as well as its molecular mechanisms and processes. However, a comprehensive summary of the methods for detecting ferritinophagy is still unclear. To further deepen the understanding of ferritinophagy and its detection methods, this review focuses on the concept, characteristics, methods, and precautions during detection of ferritinophagy. This review provided experimental reference for subsequent researchers and promoting the progress of research related to ferritinophagy. [ABSTRACT FROM AUTHOR]

In order to study the effects of fermented feed on the growth performance and intestinal structure of cherry valley ducks, a total of 360 1- day- old male cherry valley ducks were randomly divided into three groups with four replicates per group and 30 ducks per replicates in this research. Ducks in the control group were fed with normal diet, while the experimental groupsⅠ and Ⅱ were fed with normal diet supplemented with 5% and 10% fermented feed, respectively. The ducks were raised using two-stage diets for 42 days. The results showed that the average daily gain of the experimental groupⅠ was significantly higher than that of the control group (P<0.05), and the feed weight ratio was significantly lower than that of the control group (P<0.05). Compared with the control group, the length of the duodenum, ileum, cecum and rectum in the experimental groupⅠ had increased (P>0.05), and the length of the jejunum in the experimental groups were significantly higher than that in the control group (P<0.05). The villus height in the duodenum, jejunum and ileum of the experimental group Ⅰ was significantly higher than that in the control group (P<0.05). The supplementation of fermented feed was beneficial to increase the crypt depth, but there was no significant difference between the experimental groups and the control group (P>0.05). In terms of villus height/crypt depth, there was no significant difference among the groups (P>0.05). Therefore, supplementation with 5% fermented feed could reduce the feed weight ratio significantly, increase body weight gain, improve intestinal structure, and be beneficial for the healthy growth of cherry valley ducks.

Objective To explore the feasibility and clinical efficacy of super-thin scar flap in the repair of wounds in trunk and extremities after medium-sized or large keloid resection. Methods From October 2018 to November 2020, 17 patients with medium-sized or large keloids in trunk and extremities were treated in the Department of Burn and Plastic Surgery of Jining First People's Hospital, including 8 cases of shoulder and back and 9 case of extremities. The size of keloid was from 2.0 cm × 6.0 cm to 5.0 cm × 15.0 cm. The operation was performed along the central part of the long axis of keloid, and sharp dissection was made to both sides. The thickness of scar flap was from 1.5 to 2.0 mm. The scar tissue under the scar flap and the infection were completely removed, and the incision of the scar flap was closed by interrupted suture. Sixteen adult patients received superficial electron beam radiotherapy within 24 hours after operation. Ten patients received vacuum sealing drainage (VSD) treatment for 10 days after radiotherapy, and 1 child received VSD treatment for 14 days immediately after operation. Results The incisions of 17 patients healed from 14 to 21 days after operation. Sixteen patients who received electron beam radiotherapy had different degrees of local superficial necrosis of scar flap, without affecting the flap survival and wound repair. All patients were followed up for 11 to 30 months. No hyperplasia of keloid was found in all patients. Patients with small scope recurrence of keloid were treated with triamcinolone acetonide. The preserved pathological scars gradually recovered to normal scar tissue in 16 patients who received radiotherapy. Conclusion It is feasible to use super-thin scar flap to repair the wounds in trunk and extremities after medium-sized or large keloid resection. This method will not increase wounds of donor site and has positive clinical significance. [ABSTRACT FROM AUTHOR]

The widespread distribution of unconventional pollutants potentially exposes to the machinery cab, particularly with the continuous improvement of agricultural mechanization in China in recent years. Taking a tractor of Dongfanghong 1 804 as the research object, this study aims to clarify the emission characteristics of unconventional pollutants in the cab using the combination of simulation and test. 1) The diffusion process of unconventional pollutants in the cab was simulated by a Computational Fluid Dynamics (CFD) software (Fluent). The initial conditions were set at the ambient temperature of 23 ℃, where benzene was selected as a representative pollutant, considering the high carcinogenicity of benzene. Two reference sections were selected as the cross-sectional area of the breathing belt and the middle sectional area of the air supply outlet in a cab. The reason was that the breathing belt area of drivers with a great impact on the human body, while, the outlet area of air supply with a large air flow in the cab. In addition, the reference point was selected from the human breathing area, each of which was located on the connecting line between the upper part of the steering wheel and the top of the seat. The height was aligned with the height of the breathing belt of the driver and passengers. After that, a CFD simulation was conducted to obtain the temporal and spatial distribution of benzene concentration in different sections and reference points. The simulation results showed that the benzene concentration in each section basically reached equilibrium under the condition of a closed cab after 12 hours. The average benzene concentrations at the reference point and two reference sections were 1.81, 2.70, and 3.03 μg/m3, respectively, which were below the limit value required for the concentration of organic matter in the air in the vehicle. Furthermore, the pollutant concentration in the cab decreased significantly under the condition of external circulation ventilation, where the average mass percentage of benzene in two sections decreased to 1.71 and 1.98 μg/m³. Correspondingly, the entry of fresh air was conducive to the improvement of air quality in the cab. 2) A systematic test was carried out to verify the concentration of pollutants in the cab. According to HJ/t400-2007 sampling and determination s of volatile organic compounds and aldehydes and ketones in vehicles and the standard TO-17 of the National Environmental Protection Agency (EPA), the volatile organic compounds in the cab were collected by a Tenax TA tube, afterward they were analyzed by thermal desorption gas chromatography/mass spectrometry. It was found that there were a wide variety of volatile organic compounds detected in the cab of agricultural machinery, including 241 kinds of alkanes, olefins, halogenated hydrocarbons, alcohols, aldehydes, ketones, esters, and other compounds, of which alkanes accounted for the largest proportion, followed by aromatic compounds and esters. The detected concentrations of benzene, toluene, xylene, ethylbenzene, and styrene were 3.08, 30.49, 46.84, 8.39, and 2.43 μg/m³, respectively, which were lower than the maximum concentration specified in the national standard of GB/T27630-2011 guidelines for the evaluation of air quality in passenger cars. A comparison was made on the measured benzene concentration at the reference point after being closed for 16 hours with the simulation. It was found that the error range was 7.7%-10.0%, indicating the more reliable simulation. In addition, a portable handheld detector was used to detect the changing trend of total volatile organic compounds (TVOC) concentration in the cab within 18 hours at the reference point under the condition of the closed cab, in order to further verify the reliability of the numerical simulation. It was found that the TVOC concentration in the tractor cab basically reached equilibrium after 12 hours, and the changing trend was roughly the same as that of benzene concentration at the reference point during simulation, indicating the high reliability and accuracy of the model. This finding can provide a theoretical basis for further study of air quality in an agricultural machinery cab. [ABSTRACT FROM AUTHOR]

Objective To observe the effects of interactive scalp acupuncture on cognitive function, depression, anxiety and sleep quality in patients with post-stroke patients. Methods A total of 445 patients with stroke who had been admitted to the Rehabilitation Department of Nan'ao People's Hospital, Shenzhen Second People's Hospital and Shenzhen Futian District Hospital of Traditional Chinese Medicine from May 2019 to May 2020 were selected and randomly divided into the experimental group (n=223) and the control group (n=222), with 23 cases shed in the experimental group and 22 cases shed in the control group. Two groups of patients were treated with standard care and conventional rehabilitation exercise therapy. The experimental group was given interactive head acupuncture therapy, while the control group was given conventional scalp acupuncture and cognitive training therapy for a course of 8 weeks. Before the initial treatment, at the end of the treatment course, and at the follow-up 2 months later, Montreal Cognitive Assessment Scale (MoCA), Mini-mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), and Modified Barthel Index (MBI) were evaluated. The levels of serum Brain-derived Neurotrophic Factor (BDNF) and Nerve Growth factor (NGF)were measured before and after the first treatment. Results At the end of the treatment course and at the follow-up, the scores of MoCA, MMSE and MBI in the experimental group were increased compared with those before treatment (P＜ 0.01), and the scores of HAMD, HAMA and PSQI were decreased compared with those before treatment (P＜ 0.01). MoCA scores increased (P＜ 0.01) and HAMD scores of the control group decreased (P＜ 0.01) both at the end of the treatment course and at the follow-up, whereas MMSE and MBI scores of the control group increased only at the end of treatment (P< 0.01). The scores of MoCA, MMSE and MBI in the experimental group were higher than those in the control group at the end of the course and at the follow-up (P＜ 0.01), and the scores of HAMD, HAMA and PSQI in the experimental group were lower than those in the control group (P＜ 0.01). In terms of serological indexes, the levels of BDNF and NGF in both groups at the end of the course of treatment were higher than those before treatment (P＜ 0.01), and those in the experimental group were higher than those in the control group (P< 0.01). Conclusion Interactive scalp acupuncture can significantly improve not only the cognitive function, depression, anxiety but also the sleep quality and self-care ability of patients with stroke, and promote the recovery of cerebral nerve function. Compared with conventional rehabilitation treatment, it has the efficacy advantage which can be maintained after stopping the treatment. [ABSTRACT FROM AUTHOR]

For the location problem of unexploded ordnance (UXO) in the processes of conventional weapon test, military training and exercises, a low cost UXO detection method of the terminal ballistics is presented. According to the size of the impact area , many low cost acoustic sensors are installed in shooting range. The measuring range of these sensors covers the whole impact area. As for the signals of aerodynamic noise and the landing sound, which are captured by each acoustic sensor, the computation is implemented to used FFT and Laplace wavelet to denoise and enhance the original acoustic signal; use the short time energy, short time amplitude, and short time zero-crossing rate to detect the endpoint of these signals above; use the wavelet packet to collect the features of the enhanced signal; and use the minimized distance-based threshold criterion to identify the aerodynamic noise and the landing sound. The test results of UXO location in the shooting range show that the proposed technique can be used for UXO location and the location accuracy can reach 10 m. [ABSTRACT FROM AUTHOR]
