Abstract
Most of the current non-pharmacological treatment strategies for atherosclerosis (AS) suffer from poor penetration into the plaque and only aim at a certain factor in its formation process, resulting in limited therapeutic effect. Herein, a kind of nanomotor with dual-mode propulsion is constructed, which is sensitive to higher reactive oxygen species (ROS) at the AS site and near-infrared (NIR) laser by the covalent binding and self-assembly of β-cyclodextrin (β-CD) and L-arginine (LA) with immobilization of Au nanoparticles. NIR laser irradiation can be used as a driving force and to ablate inflammatory macrophages through the photothermal effect. The nitric oxide (NO) released by the nanomotors can be used as another driving force and a therapeutic agent to promote endothelial repair in the plaque site. LA can eliminate ROS in the inflammatory site, and β-CD can promote the removal of cholesterol from foam cells. In particular, the two driving modes of nanomotors synergistically promote their aggregation and penetration in the plaque. This kind of nanomotor can regulate the microenvironment of AS in multiple ways, including combination therapy for endothelial repair, lipid clearance, and reducing ROS, which is expected to become a potential non-pharmacological strategy in the treatment of AS.

Abstract
Objective: To explore the trend of disease burden of degenerative mitral valve disease (DMVD) in the Chinese population from 1990 to 2019. Methods: Based on the 2019 Global Burden of Disease database (GBD 2019), the number of patients, the number of new cases, the number of deaths, the disability-adjusted life years (DALY) as well as the prevalence, incidence and death rate, DALY rate and their age-standardized rates were used to analyze the trend of the burden of DMVD in the Chinese population from 1990 to 2019. Results: In 2019, the number of patients, the number of new cases, and the number of deaths with DMVD in China were 461.2, 27.0 and 0.129 ten thousand, respectively, which increased by 209.0%, 199.1% and 13.2% when compared with 1990. In 2019, the age-standardized prevalence, incidence and death rate were 228.1/100 000, 12.7/100 000 and 0.075/100 000, respectively. Compared with 1990, the change of the age-standardized prevalence, incidence and death rate were 32.6%, 42.8% and -54.1%, respectively. In addition, the 2019 data also showed that the age-standardized prevalence and incidence were higher in females than in males (the age-standardized prevalence was 190.1 (181.5-198.9)/100 000 for males and 262.0 (250.3-273.9)/100 000 for females); the age-standardized incidence was 10.5 (10.0-11.0)/100 000 for males and 14.9 (14.3-15.6)/100 000 for females. The age group with the largest number of DMVD patients was 65 to 69 years old, and the highest incidence was 60 to 64 years old. From 1990 to 2019, DALY caused by DMVD showed an upward trend in China, from 46 439 person-years in 1990 to 69 402 person-years in 2019, with an increase of 49.4%. While the age-standardized DALY rate continued to decline, from 5.5/100 000 in 1990 to 3.8/100 000 in 2019, with a drop of 30.8%. The DALY and the age-standardized DALY rate of females were always higher than that of males in different years. Conclusion: From 1990 to 2019, DALY and the age-standardized prevalence and incidence of DMVD in China shows an increasing trend, and the disease burden caused by DMVD is severe in China.

Abstract
In underground coal mines, the drilling process in roof bolting operation could generate excessive amount of respirable coal and quartz dusts. Improper drilling control might also pose safety hazard and interrupt production. Therefore, an automated, high-efficiency drilling control system with safety features can be beneficial to the bolter personnel. In this research, a comprehensive drilling control algorithm has been developed to reduce the generation of respirable dust and to increase the drilling energy efficiency based on laboratory drilling test results and safety considerations. Specific energy is used to evaluate the energy efficiency. In addition, the ratio between specific energy and rock uniaxial compressive strength can be used as a basis for determining the rational drilling bite depth-typically a determined high one permissible by the driller power and drill steel. The test results show that to achieve and maintain a desired drilling bite depth for good drilling performance, a combination of relatively low rotational rate and a rationally high penetration is preferred. By monitoring the drilling rate, the system is able to evaluate the bit wear condition and improve drilling safety. In this paper, the developed drilling control algorithm for achieving a rational drilling bite depth is demonstrated. By adapting this drilling control algorithm, the drilling efficiency and bit condition can be monitored in real time, so the system can maintain a relatively high energy efficiency, generate less respirable dust, and avoid drilling failure.

Abstract
During a person's entire life, nutrition is essential for growth, development, maintenance, reproduction, disease control and health. Based on a brief review of existing research on lifelong nutrition, this article focuses on the relationship between early life nutrition and noninfectious chronic diseases (NCDs) in adulthood. It points out that early life is the most important stage, with the rapid growth and development of the body and strong requirements for energy and nutrients. Due to the "metabolic memory", insufficient or imbalanced nutrition at this stage affects not only the growth and development of the body, but also leads to increased risks of NCDs in adulthood. In addition to early life, the reasonable intake of nutrients in throughout life plays an important role in meeting the basic requirements of the body and the control of NCDs.

Abstract
The SARS-CoV-2 Delta variant has spread rapidly worldwide. To provide data on its virological profile, we here report the first local transmission of Delta in mainland China. All 167 infections could be traced back to the first index case. Daily sequential PCR testing of quarantined individuals indicated that the viral loads of Delta infections, when they first become PCR-positive, were on average ~1000 times greater compared to lineage A/B infections during the first epidemic wave in China in early 2020, suggesting potentially faster viral replication and greater infectiousness of Delta during early infection. The estimated transmission bottleneck size of the Delta variant was generally narrow, with 1-3 virions in 29 donor-recipient transmission pairs. However, the transmission of minor iSNVs resulted in at least 3 of the 34 substitutions that were identified in the outbreak, highlighting the contribution of intra-host variants to population-level viral diversity during rapid spread.

Abstract
Background MicroRNAs (miRs) are endogenous, single-stranded, noncoding RNAs that are involved in various physiological processes, and the development and the progression of various types of cancer. Specifically, the role of miR-200a-3p has been implicated in various types of cancer in contributing to a diverse array of cancer types has been previously reported. The present study aimed to investigate the expression levels of miR-200a-3p in human bladder cancer, as well as its potential role in disease pathogenesis. Methods Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the expression of has-mir-200a-3p and tumor necrosis factor α (TNF-α) induced protein 3 (A20) in tumor tissues and cell lines. Dual-luciferase reporter assay and combination with the expression intervention of hsa-mir-200a-3p and A20 in bladder cancer cell lines to clarify the binding relationship between hsa-mir-200a-3p and A20.After the expression intervention of hsa-mir-200a-3p and A20 in bladder cancer cells, the changes of cell proliferation, cell apoptosis, cell cycle, wound-healing ability and migration ability were detected by CCK8, flow cytometry, wound-healing and Transwell methods. Xenograft transplantation model was performed subcutaneously in nude mice by implantation of J82 and T24 cells, and then the bladder cancer growth curve was calculated from mice exposed to has-mir-200a-3p minic or minic-NC. Results Bladder cancer tissues demonstrated significantly upregulated miR-200a-3p expression levels. Moreover, increased miR-200a-3p expression was significantly associated with distant metastasis and advanced stage. In addition, compared with the miR-control (Ctr) group, miR-200a-3p overexpression promoted bladder cancer cell proliferation, migration, invasion, cell cycle, and release of inflammatory cytokines, but inhibited cell apoptosis. Mechanistically, A20 was identified as a target gene of miR-200a-3p in bladder cancer cell lines. Moreover, compared with the miR-Ctr group, the miR-200a-3p overexpression group exhibited significantly promoted tumor growth in vivo, and A20 overexpression blocked the promoting effect of miR-200a-3p on bladder cancer. Conclusions The results of the present study indicated that miR-200a-3p might serve act as an oncogene in human bladder cancer by targeting a novel the gene A20 gene; therefore, miR-200a-3p and A20 might serve could serve as novel therapeutic targets for bladder cancer.

Abstract
Mesenchymal stem cells (MSCs) are well known for their multi-directional differentiation potential and are widely applied in cartilage and bone disease. Synovial mesenchymal stem cells (SMSCs) exhibit a high proliferation rate, low immunogenicity, and greater chondrogenic differentiation potential. Microtubule (MT) plays a key role in various cellular processes. Perturbation of MT stability and their associated proteins is an underlying cause for diseases. Little is known about the role of MT stabilization in the differentiation and homeostasis of SMSCs. In this study, we demonstrated that MT stabilization via docetaxel treatment had a significant effect on enhancing the chondrogenic differentiation of SMSCs. MT stabilization inhibited the expression of Yes-associated proteins (YAP) and the formation of primary cilia in SMSCs to drive chondrogenesis. This finding suggested that MT stabilization might be a promising therapeutic target of cartilage regeneration.

Abstract
Reticuloendotheliosis virus (REV) is an avian oncogenic retrovirus that causes atrophy of immune organs, such as the spleen, thymus, and bursa of Fabricius, leading to severe immunosuppression. However, there is limited information describing the genes or microRNAs (miRNAs) that play a role in replicating REV-spleen necrosis virus (SNV). Our previous miRNA and RNA sequencing data showed that the expression of gga-miR-222b-5p was significantly upregulated in REV-SNV-infected chicken spleens of 7, 14, and 21 dpi compared to non-infected chicken spleens, but mitogen-activated protein kinase 10 (MAPK10), which is related to innate immunity, had the opposite expression pattern. To understand chicken cellular miRNA function in the virus-host interactions during REV infection, we used quantitative reverse transcription PCR (qRT-PCR) to determine whether the expression of gga-miR-222b-5p and MAPK10 in the spleen of specific-pathogen-free chickens at 28, 35, and 42 dpi was consistent with the first 3 time points, and dual-luciferase reporter assay was used to determine the targeting relationship between gga-miR-222b-5p and MAPK10. Results show that MAPK10 was downregulated at all 3 time points; however, significant difference (p⟨0.01) was noted only at 35 dpi. Moreover, the expression of gga-miR-222b-5p was upregulated; however, significant difference (p⟨0.01) was observed only at 28 and 35 dpi. A dual-luciferase reporter assay showed that MAPK10 is a direct target of gga-miR-222b-5p. This study suggests that gga-miR-222b-5p may target MAPK10 to promote the REV-SNV-induced tumorigenesis via the RLRs signaling pathway.

Abstract
Kidney renal clear cell carcinoma (KIRC) is the subtype pf kidney cancer having the highest mortality as well as the highest potential of invasion and metastasis. The expression of HADH, encoding a key enzyme in fatty acid β-oxidation, has rarely been reported to correlate with prognosis and immune infiltration in cancers. This study aimed to explore the prognostic value of HADH in patients with KIRC. Gene expression profiles and clinical data of KIRC patients were acquired from The Cancer Genome Atlas. We compared the expression of HADH between KIRC tissues and normal tissues. Then, the relationship between HADH expression and the clinicopathological characteristics (survival, age, gender, stage, and grade) of KIRC was explored. Data from several online databases and paraffin-embedded specimens from two cohorts were used for external validation (10 cases from Meizhou People's Hospital and another 75 cases from a tissue chip, with both cohorts including KIRC samples and paired normal tissues). We also predicted the fractions of tumor-infiltrating immune cells (TIICs) in various tissues using CIBERSORT. Next, we estimated the prognostic value of differences in TIIC proportions between the high and low HADH expression groups. Finally, gene set enrichment analysis (GSEA) was performed to explore the potential mechanisms by which HADH expression influences patient survival. The expression of HADH was significantly lower in KIRC tissue than in normal tissue. Decreased expression of HADH was significantly correlated with high histologic grade, advanced stage, and poor prognosis. The differential expression of HADH was validated at the protein level by immunohistochemistry. Multivariate Cox regression analysis indicated that HADH was an independent prognostic factor for KIRC. In addition, HADH expression was significantly associated with the accumulation of several TIICs, especially regulatory T cells. Finally, GSEA revealed that the transcriptome of the low HADH expression group was significantly enriched in genes involved in not only epithelial-mesenchymal transition and inflammatory response but also TNF-α, IL-6-JAK-STAT3, and interferon-γ signaling. In conclusion, our study demonstrated that decreased expression of HADH is related to poor prognosis and immune infiltration in KIRC; this finding may provide crucial information for the development of immunotherapies.

Abstract
Objective: To explore the relationship between non-alcoholic fatty liver disease and sarcopenia in patients with type 2 diabetes mellitus. Methods: 792 cases with type 2 diabetes mellitus who were hospitalized in the Endocrinology Department of the First Affiliated Hospital of Chongqing Medical University from June 2013 to December 2015 were enrolled in this cross-sectional study. Liver ultrasound examination and dual-energy X-ray absorptiometry (DXA) were used to examine the body composition. Patients were grouped according to gender and whether or not they had combined NAFLD, and indicators such as age, duration of diabetes, body mass index (BMI), waist circumference, biochemical indicators, skeletal muscle mass index (SMI), prevalence of sarcopenia, and medication status were collected. An independent-sample t-test, two-sample Kolmogorov-Smirnov test or χ (2) test were performed on the data. Logistic regression model was used to analyze the correlation between NAFLD, sarcopenia and SMI in diabetic patients of different genders. Results: The average age of 792 cases were (64.54 ± 9.61) years, and there were 301 (38%) patients with NAFLD. The prevalence of sarcopenia in male and female NAFLD patients was significantly higher than non-NAFLD patients (male 20.2% and 9.9%, χ(2) = 9.67, P = 0.002; female 12.2% and 5.1%, χ(2) = 5.64, P = 0.018). Male SMI (30.92 ± 2.31 and 31.81 ± 2.17, P < 0.001) and female SMI (25.48 ± 2.14 and 26.34 ± 2.28, P < 0.001) in NAFLD patients were significantly lower than non-NAFLD patients. Multivariate logistic regression analysis showed that sarcopenia was an independent risk factor for NAFLD in male patients with type 2 diabetes mellitus (OR = 2.006, 95% CI: 1.012 ~ 3.976, P = 0.046). There was no correlation between sarcopenia and NAFLD in female patients after adjusting for clinical risk factors. Conclusion: There is an independent correlation between sarcopenia and NAFLD in male patients with type 2 diabetes, and sarcopenia may be an independent risk factor for male patients with NAFLD.
