Traditional acoustic design of heating, ventilation and air conditioning (HVAC) system mostly relies on the experience of designers, with significant repetition and minimal automation. To achieve the goal of intelligent design, methods such as directed acyclic graph, weighted directed adjacency matrix, and visualization were applied in the acoustic design of ventilation duct system. An algorithm was proposed to automatically calculate the noise levels at any place, whether in the duct or a specific room. The key components such as building 3D models, designing noise attenuation diagram, determining acoustic path, solving acoustic unit, and visualizing acoustic results were included in this system. The results show that this system is robust, accurate and quick to respond. The deviation between results from traditional methods and the proposed algorithm is no more than ± 2%, and the computation time is less than 0.2s, whereas the running time for some small and medium ventilation systems is within 0. 1s. The results based on this algorithm can be combined with 3D models to visualize the change of noise values and provide a reference in the design process of HVAC systems. [ABSTRACT FROM AUTHOR]

Objective To investigate the underlying mechanism of microglia ferroptosis in smoke inhalation-induced (SII) brain injury. Methods Twenty SPF-grade male C57BL/6 mice were randomly divided into the control group, the SII group, the ferrostatin-1 group (Fer-1, 2.5 mmol/kg) and the deferoxamine group (DFO, 200 mg/kg), with 5 mice in each group. Mice in the Fer-1 group and the DFO group were intraperitoneally injected with Fer-1 and DFO 1, 3 and 5 day after smoke exposure, respectively. The pathological changes of brain tissue were examined by HE staining and Prussian blue staining on the 6th day after smoke exposure. RT-qPCR was used to detect levels of inflammatory factors, brain tissue damage markers and ferroptosis markers. The contents of iron in mouse brain tissue were determined by double pyridine colorimetric assay. The contents of malondialdehyde (MDA) and lipid peroxide (LPO) in mouse brain tissue were determined by thiobarbituric acid (TBA) colorimetric assay. Superoxide dismutase (SOD) activity in mouse brain tissue was measured by xanthine oxidase assay kit. The contents of glutathione (GSH) in mouse brain tissue were determined by direct method of dithiodinitrobenzoic acid (DTNB) assay. BV2 cells were cultured in complete DMEM medium and divided into the control group, the erastin group (10 µmol/L), the Fer-1 group (erastinc stimulation combined with 5 mmol/L Fer-1 treatment) and the DFO group (erastinc stimulation combined with 50 mmol/L DFO treatment). After 24 h, cell viability was detected by CCK-8 assay, cell apoptosis was detected by Annexin V-FITC/PI flow cytometry, intracellular reactive oxygen species (ROS) production was detected by DCFDA staining, and mitochondrial membrane potential was detected by MitoTracker Red CMXRos staining. Results Compared with the control group, enhanced iron deposition and inflammation in brain tissue, elevated mRNA expression of inflammatory markers and damage markers in brain tissue, up-regulated ACSL4 and NCOA4 mRNA levels, down-regulated GPX4 and SLC7A11 mRNA levels, decreased GSH and SOD contents, and increased LPO and MDA contents were observed in brain tissue of the SII group (P＜0.05). The mRNA expression level of 7 member of solute carrier family 11 (SLC7A11) was decreased in mice of the SII group. The contents of GSH and SOD were decreased, and the contents of LPO and MDA were increased (P＜0.05). Compared with the SII group, all the above parameters were reversed in the Fer-1 group and the DFO group, and the damage of mouse brain tissue was alleviated (P＜0.05). In BV2 cell experiments, compared with the control group, decreased survival rate of BV2 cells and increased apoptosis rate were found in the erastin group (P＜0.05), and increased intracellular ROS level and decreased mitochondrial membrane potential were also observed in the erastin-stimulated BV2 cells. The above parameters were opposite to those of the erastin group in the Fer-1 group and the DFO group (P＜0.05), and the oxidative damage of BV2 cells was alleviated. Conclusion The ferroptosis inhibitors Fer-1 and DFO can inhibit microglia ferroptosis and alleviate smoke inhalation-induced brain injury. [ABSTRACT FROM AUTHOR]

Objective Explore the relationship between semen quality and trace element levels in seminal plasma, as well as miR-184 levels in exosomes of male infertility patients. Methods 155 male infertility patients in our hospital from January 2022 to July 2023 were selected as the infertility group, and another 155 male patients with normal physical examination during the same period were selected as the normal group. Compare the general information, semen quality parameters, trace elements, and miR-184 levels in exosomes between two groups, and analyze the correlation between male infertility patients and the above laboratory indicators through Spearman rank correlation analysis. Results The sperm concentration, total sperm motility （PR + NP）, forward motility sperm （PR）, average curve velocity, average linear velocity, average path velocity, and average lateral amplitude of sperm head （ALH） in the infertile group were lower than those in the normal group （P < 0.05）; The levels of Zn, Mg, and Ca in the infertile group were lower than those in the normal group, while the levels of Cu, Pb, and relative expression of miR-184 were higher than those in the normal group （P < 0.05）; The levels of Zn and Cu elements in male infertility patients are positively and negatively correlated with sperm concentration, total sperm motility （PR+NP）, and forward motility sperm （PR）, respectively. The levels of Pb elements are negatively correlated with the average lateral amplitude of sperm head （ALH）, and P < 0.05. The relative expression level of miR-184 in male infertility patients is negatively correlated with sperm concentration, total sperm motility （PR + NP）, forward motility sperm （PR）, and average sperm curve velocity, with P < 0.05. Conclusion The quality of semen in male infertility patients is closely related to the levels of trace elements in semen and miR-184 levels in exosomes. [ABSTRACT FROM AUTHOR]

铁死亡是近些年新发现的一种程序性细胞死亡方式，参与到多种急性和慢性疾病的病 理过程中，其引发机制主要包括铁依赖性的活性氧自由基蓄积和多元未饱和脂肪酸的消耗。卒中一 直以高死亡率和致残率受到全世界研究者的广泛关注，但关于铁死亡在卒中致病机制中的研究目前 还较少，本文分别从铁死亡与出血性及缺血性卒中两方面对已有的最新研究成果进行回顾总结。 Abstract: Ferroptosis is a newly discovered programmed cell death in recent years, which involves the pathogenesis of many acute and chronic diseases. The mechanism mainly includes that ferroptosis can trigger iron-dependent accumulation of reactive oxygen species(ROS) and consumption of plasma polyunsaturated fatty acids. Though there are numerous studies on stroke, studies on the effect of ferroptosis in the pathogenesis of stroke are very few. This article reviewed the advances in ferroptosis in the pathogenesis of hemorrhagic and ischemic stroke.

Objective To explore the the effect and possible mechanism of heat stress at different rewarming time on the damage of human skeletal muscle cells (HSKMC). Methods HSKMC in the logarithmic growth phase were divided into the heat stress group and control group. Cells in the control group were cultured normally, and the heat stress models were established in the heat stress group and then were rewarmed in 37 ℃ and 5% CO2 cell incubator for 0, 6, 12 and 24 h, respectively. The cell survival rate was detected by CCK-8, the cell ultrastructure was observed by transmission electron microscopy, TRPV4 protein was detected by Western blotting, and TRPV4 mRNA was detected by real-time fluorescence quantitative PCR. HSKMC in the logarithmic growth phase were randomly divided into the HS group, GSK+HS group, HC+HS group, and NC group. Cells in the NC group were cultured normally, and the heat stress models were established in the other three groups, and the rewarming time was 12 h. Cells in the GSK+HS group and HC+HS group were given TRPV4 agonist GSK1016790A (500 nmol) and TRPV4 inhibitor HC-067047(5 µmol) at 0. 5 h before heat stress, and Ca2+ level was detected by flow cytometry. Results Compared with the control group, the survival rate of cells in heat stress group decreased after rewarming for 0, 6, 12 and 24 h (P<0. 05). With the extension of rewarming time, the survival rate of cells in the heat stress group decreased successively, and significant difference was found between these two groups (all P<0. 05). Compared with the control group, ultrastructural changes were observed in the cells in the heat stress group after rewarming for 0 and 6 h, which were mainly manifested as cell swelling, enlarged volume, cytoplasmic vacuolation, obvious mitochondrial swelling, degranulation, double ridge loss, widening of perinuclear space, nucleus condensation and contraction, and interruption of some envelope continuity. After rewarming for 12 and 24 h, the cells in the heat stress group even showed nucleolysis and disappearance, nucleus fragmentation, chromatin boundary aggregation, and cytoplasmic structure disintegration and granulation. Compared with the control group, the relative expression levels of TRPV4 mRNA and protein in heat stress group increased after rewarming for 0, 6, 12 and 24 h (all P<0. 05). The levels of intracellular Ca2+ in the NC group, HC+HS group, HS group and GSK+HS group increased successively, and significant difference was found between groups (all P<0. 05). Conclusions Heat stress can reduce HSKMC survival rate and damage HSKMC structure. The longer rewarming time after heat stress, the greater the damage to HSKMC cells. The mechanism may be related to the promotion of TRPV4 expression and its mediated Ca2+ influx. [ABSTRACT FROM AUTHOR]

This paper takes16 prefecture-level and above cities in the Chengdu-Chongqing economic circle as the object to observe the current situation of economic talent training in Chengdu-Chongqing area, and explores the promotion ways of economic talent training to meet the needs of the development of new culture. This study finds that the overall distribution of university resources in the Chengdu-Chongqing economic circle is highly concentrated in Chengdu city and Chongqing city, and more than 30% of the cities do not have undergraduate universities. From the perspective of economics talent training, half of the cities in the Chengdu-Chongqing economic circle do not have conditions for the cultivation of economics undergraduate talents. At the same time, there is an obvious gap between the Chengdu-Chongqing economic circle and other developed urban agglomerations in China in terms of economic basis and top-notch talent training. Finally, on the basis of summing up the experience of economic talent training in developed regions at home and abroad, this paper puts forward ways to improve the economic talent training ability from the aspects of cooperation, target positioning, management mechanism, curriculum and teaching staff.

After entering the new century, especially since the outbreak of COVID-19, China's public health social work has been valued by the people of all circles, and relevant practical exploration and theoretical research have been continuously deepened. The research framework has been formed in seven aspects, including value ethics, theoretical perspective, methods and technologies, development mode, practical field, social policy and foreign experience. While the research results have been enriching, the perspectives have been broadening, and the influence has been expanding, the existing researches are faced with limitations such as narrow scope of research achievements, relatively single research methods, unclear core competence and lagging disciplinary discourse system. Future research on social work in public health should enrich the research content and dimension, expand research perspective and methods, reflect on the purpose of research, focus on core competence, construct the disciplinary discourse system, and enhance the discourse power of disciplines.
