针对无线通信传统接收机的信道估计和译码分开处理是次优的问题,文章提出了一种联合信道估计和极化码译码的接收机模型。根据极化码译码器级联的循环冗余校验码的校验信息,接收机将译码器中部分硬判决信息再编码,然后将得到的码字反馈到信道估计器中,此时相当于接收机挑选了部分码字比特作为导频,信道估计器根据新的导频重新进行信道估计。文章提出的接收机模型及算法不仅减少了信道估计中导频的开销,还使得信道估计和译码两个过程相互促进,从而改善了极化码的误帧率。仿真结果表明,当归一化多普勒等于0.02时,文章提出的基于硬判决反馈的接收机相比于传统的接收机有2 dB的性能增益。

Objective To explore the clinical efficacy of Fuling Zexie Decoction combined with lifestyle intervention in patients with metabolic syndrome (MetS) of dampness syndrome. Methods A total of 40 patients with MetS of dampness syndrome were randomly divided into experimental group (n=20) and control group (n=20) according to a randomized double-blind placebo-controlled design. The experimental group was given oral administration of Fuling Zexie Decoction, the control group was given placebo, 150 mL each time, twice a day. Both groups were given healthy lifestyle (healthy eating habits and exercise mode) education. The intervention period was 16 weeks. Traditional Chinese medicine dampness syndrome scale score and the diagnostic indexes of Mets, including waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and fasting blood glucose (FBG), were evaluated before and after treatment. Other metabolic indexes such as body mass index (BMI), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), homeostasis model assessment of insulin resistance (HOMA-IR), uric acid (UC), as well as inflammation related indexes including C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor (TNF-α) were also evaluated. Results A total of 33 people completed the trial, including 17 people in the experimental group and 16 people in the control group. Compared to the baseline period, FBG, BMI, LDL-C and dampness syndrome scale score in the experimental group were significantly decreased at the 8th and 16th week of intervention (P<0.05). WC was significantly decreased at the 8th week of intervention (P<0.05). CRP showed a downward trend at the 16th week of intervention (P<0.05). Moreover, SBP and IL-6 in control group decreased significantly at the 8th and 16th week of intervention (P<0.05). WC, DBP and HOMA-IR decreased significantly at the 8th week of intervention (P<0.05). There was no significant difference in other outcome indexes between the two groups at the 8th and 16th week of intervention (P>0.05). The safety indexes of all patients before and after intervention were not significantly abnormal, and no serious adverse events occurred. Conclusion This study initially shows the positive regulatory effect of Fuling Zexie Decoction combined with lifestyle on metabolism and inflammation-related indexes in people with MetS of dampness syndrome, which helps to improve the level of dampness syndrome and provides a basis for further research.

The traditional detection of rust defects on segmental beams relies on manual identification, which poses high safety risks, low detection efficiency, and unstable accuracy. In order to solve these problems, a segment beam rust detection algorithm based on improved YOLOv5s was proposed, and the attention mechanism CBAM (convolutional block attention module) of channel attention and spatial attention fusion was added to the backbone network module to enhance the ability to extract features. The bi-directional weighted feature pyramid network structure BiFPN (bi-directional feature pyramid networ) was integrated into the neck network module to improve the network’ s detection ability. The efficient intersection over union loss EIoU was combined with Alpha-IoU, which can perform power operation on the loss function, to generate an Alpha-EIoU Loss function to replace the original complete intersection over union loss CIoU, reduce the loss value and further improve the overall performance of the model. After experiments, it has been shown that the improved algorithm outperforms the original YOLOv5s algorithm in terms of accuracy, recall mAP@ 0. 5 and mAP@ 0. 5∶ 0. 95 have increased by 2. 8%, 3. 0%, 2. 0%, and 5. 4% respectively, without adding too many parameters. After the validation of a virtual scene designed by the 3D modeling software 3dsMax, this algorithm can achieve high recognition accuracy in various backgrounds and has strong robustness. It has important theoretical significance and engineering value for the deployment of rust detection in prefabricated segmental beams. [ABSTRACT FROM AUTHOR]

BACKGROUND: Psoralen has a strong anti-osteoporotic activity and may have a restorative effect on chemotherapy-induced osteoporosis. OBJECTIVE: To explore the restorative effect of psoralen on the osteogenic differentiation of bone marrow mesenchymal stem cells in mice inhibited by cyclophosphamide and its mechanism. METHODS: C57BL/6 mouse bone marrow mesenchymal stem cells were isolated and cultured. Effect of psoralen on viability of bone marrow mesenchymal stem cells was detected by MTT assay. Osteogenic induction combined with alkaline phosphatase staining was used to determine the optimal dose of psoralen to restore the osteogenic differentiation of bone marrow mesenchymal stem cells inhibited by cyclophosphamide. The mRNA expression levels of Runx2, alkaline phosphatase, Osteocalcin, osteoprotegerin, and Wnt/β-catenin signaling pathway-related genes Wnt1, Wnt4, Wnt10b, β-catenin, and c-MYC were measured by RT-qPCR at different time points under the intervention with psoralen. The protein expression of osteogenic specific transcription factor Runx2 and Wnt/β-catenin signaling pathway related genes Active β-catenin, DKK1, c-MYC, and Cyclin D1 was determined by western blot assay at different time points under the intervention with psoralen. RESULTS AND CONCLUSION: (1) There was no significant effect of different concentrations of psoralen on the viability of bone marrow mesenchymal stem cells. The best recovery of the inhibition of osteogenic differentiation of bone marrow mesenchymal stem cells caused by cyclophosphamide was under the intervention of psoralen at a concentration of 200 μmol/L. (2) Psoralen reversed the reduction in osteogenic differentiation marker genes Runx2, alkaline phosphatase, Osteocalcin and osteoprotegerin mRNA expression and Runx2 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium. (3) Psoralen reversed the decrease in Wnt/β-catenin pathway-related genes Wnt4, β-catenin, c-MYC mRNA and Active β-catenin, c-MYC, and Cyclin D1 protein expression and the increase in DKK1 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium. (4) The results showed that cyclophosphamide inhibited osteogenic differentiation of bone marrow mesenchymal stem cells in mice, and psoralen had a restorative effect on it. The best intervention effect was achieved at a concentration of 200 μmol/L psoralen, and this protective effect might be related to the activation of Wnt4/β-catenin signaling pathway by psoralen.

BACKGROUND: Gait is one of the optimal indicators of functional status in older adults. Gait parameters are associated with adverse health outcomes in older adults. OBJECTIVE: To summarize and compare the practical value of gait parameters, and to review the progress of research on spatio-temporal parameters and the risk of adverse health outcomes in older adults. METHODS: PubMed, Web of Science, and CNKI were searched for relevant literature published from January 2010 to June 2023 using the search terms of “gait speed, walking speed, step length, cadence, step frequency, step time, walking base, aged and elderly” in English and Chinese, respectively. A total of 52 papers were finally included for the systematic review. RESULTS AND CONCLUSION: Currently, researchers have focused on three basic temporal-spatial parameters, namely, step speed, step length and step frequency, to explore their association with adverse health outcomes in older adults. Reduced gait speed in older adults may increase the risk of falls, all-cause mortality, and may be an independent predictor of all-cause mortality. Older adults with slow gait speed are at higher risk of cognitive decline, and may be the preferred gait parameter in assessing cognitive impairment in older adults. Older adults with slow gait speed are more likely to have debilitating or common chronic illnesses, and are at higher risk of hospitalization and public care. Step length is positively correlated with individual height and lower limb length, but age-induced shortening of step length is not related to height or lower limb length, and shortening of step length reflects reduced physical function in older adults, and shortening of step length is a risk factor for falls and cognitive decline in older adults. Stride frequency is often used as a measure of exercise intensity, and a stride frequency of ≥ 100 steps/minute is predictive of all-cause mortality, and slowing of step frequency may lead to a higher risk of falls, hospitalization and all-cause mortality in older adults. Changes in gait parameters are closely related to the level of physical fitness in older adults, and there may be a bidirectional relationship between the two. The results of the study will provide a theoretical basis for further improving risk screening in clinical populations, refining health risk assessment in the elderly, improving health protection and promoting active health in the elderly.

Objective: To verify whether phosphoglycerate mutase 1 (PGAM1) allosteric inhibitor could enhance the sensitivity of colon cancer cells to oxaliplatin (OXA). Methods: OXA sensitivity and PGAM1 expression levels of four consensus molecular subgroups (CMS) of colon cancer cells were analyzed according to genomics of drug sensitivity in cancer (GDSC）and cancer cell line encyclopedia (CCLE) databases. CCK8 assay and Annexin V/PI staining were used to investigate the effect of PGAM1 allosteric inhibitor HKB99 on the proliferation and apoptosis of human colon cancer cell lines. CCK8 assay were performed to investigate the effect of HKB99 combined with OXA on the proliferation of colon cancer DLD-1 cells and cooperativity index was analyzed according to the result. Results: Firstly, GDSC and CCLE databases results showed that CMS1 and CMS4 colon cancer cells were less sensitive to OXA than CMS2 and CMS3 cells in terms of the sensitive cells proportion. Compared with, the expression of PGAM1 was higher in CMS1 and CMS4 cells than in CMS1 and CMS3 cells (P＜0. 05). HKB99 significantly inhibits the proliferation of SW480, SCUN2B and DLD-1 cells, with an IC50 of approximately 1μM. Annexin V/PI staining results showed that apoptosis of DLD-1 cells was significantly increased compared with Control group after HKB99 treatment (P＜0. 01). Results of CCK8 assay result showed that 1. 5μM HKB99 significantly enhanced the inhibitory effect of OXA on colon cancer DLD-1 cells compared with control group (IC50: 0. 37 vs 3. 26μM). The cooperativity index analysis result showed that the synergistic coefficient of OXA with HKB99 was less than 1 at the concentration between 1. 56μM and 25μM. Conclusions: In this study, we found that CMS1 and CMS4 colon cancer cells are less sensitive to OXA and higher level of PGAM1compared with CMS2 and CMS3 cells. An allosteric inhibitor of PGAM1, HKB99, enhances the sensitivity of colon cancer cells to OXA, which suggests that HKB99 may enhance the sensitivity of OXA chemotherapy and provide a potential treatment strategy for patients with individualized chemotherapy in colon cancer.

In order to evaluate the relationship between human and water quantitatively, taking Xi'an City as an example, the evaluation index system of human and water harmony was built on the basis of the concept of human and water harmony. The weights of each index were calculated by improving G1 weighting method. Based on the comprehensive development level of water system and human system, the coupling coordination model was used to calculate the coordination degree of human water system, and the obstacle factors were identified by the obstacle degree model. The evaluation method of single index quantification, multi-index synthesis and multi-criteria integration was adopted to calculate the health degree of effluent system and the development degree of human system, and then integrate with the coordination degree of human water system, and finally got the evaluation result of human water harmony in Xi'an City from 2012 to 2021. The results show that the man-water coordination degree of Xi'an City is gradually improved, and the obstacle degree of each index to the coordinated development of man-water system in each year is clearly visible, and the harmony of man-water is also improved from less harmonious to harmonious level. The evaluation results of this method are consistent with the actual results and have good applicability. The identification of obstacle factors is instructive to further improve the harmony between human and water. [ABSTRACT FROM AUTHOR]

Post-traumatic olfactory dysfunction (PTOD) is a common but underdiagnosed problem, and most patients do not receive effective treatment. Currently, there is a lack of diagnosis and treatment guidelines for PTOD in China. This article systematically explores the epidemiology, pathogenesis, diagnostic methods, and treatment measures of PTOD by reviewing related literature. The subjective and objective assessment methods of PTOD and treatment measures including drugs and olfactory training are summarized. It is pointed out that there is relatively little epidemiological data on PTOD, and the pathogenesis involves multiple locations including the nasal cavity, olfactory nerve, and brain.
