Abstract Objective: To examine the mental health status and related factors in children and adolescents, and to assess age groups and sexes differences in factors influencing mental health. Methods: This cross-sectional study was performed on Chinese children aged 6-18 years from November 2021 to January 2022. Mental health difficulties were accessed by the Strengths and Difficulties Questionnaire. Multivariate logistic regression was used to analyze factors associated with mental health status. Multiple linear regression was used to evaluate factors associated with the scores of the Strengths and Difficulties Questionnaire. Results: The prevalence of mental health difficulties was 12.98% (n =1348). Age (OR, 0.909, [95%CI, 0.830-0.996]), sex (OR, 1.424, [95%CI, 1.033-1.963]) and screen time on weekdays (“≥2” h/d vs “< 1” h/d: OR, 2.001, [95%CI, 1.300-3.080]) were related factors for mental health difficulties. For children (year ≤ 12), the strongest related factor for mental health difficulties was screen time on weekdays (“≥ 2” h/d vs “< 1” h/d: OR, 1.821 [95%CI, 1.203-2.755]). The risk of mental health difficulties in females with ≥ 2 h/d screen time on weekends was 3.420 times higher than those with < 1 h/d (OR, 3.420, [95%CI, 1.923-6.081]). Conclusion: The prevalence of mental health difficulties among children and adolescents was relatively high. The lower age, female sex and excessive screen time were associated with a higher risk of mental health difficulties. The factors influencing mental health varied by different age groups and sexes. Thus, specific measures for different age groups and sexes should be adopted to mitigate the impact.

Abstract Introduction This study aims to explore Programmed Death Receptor-1 (PD-1) and Programmed Death Ligand-1 (PD-L1) variations in Lung Cancer (LC) tissues and Peripheral Blood (PPB) and their association with immunotherapy efficacy and prognosis. Method 72 patients with LC were included in the LC group and 39 patients with concurrent benign lung disease were included in the benign group. PD-1/PDL-1 was compared in PPB and lung tissue. All LC patients were treated with immunotherapy. The relationship between PD-1/PDL-1 in LC tissue and PPB and immunotherapy efficacy was analyzed. Patients were divided into death and survival groups, and PD-1/PDL-1 in tumor tissues and PPB were compared. Results The authors found that PD-1 and PDL-1 positive expression in lung tissue and PPB in LC patients was elevated. Combined detection of PD-1 and PDL-1 was effective in diagnosing LC and evaluating the prognosis of LC patients. PD-1 and PDL-1 positive expression was reduced after disease remission while elevated in dead patients. The 3-year survival rate of patients with PD-1 positive expression was 45.45 % (25/55), which was lower (82.35 %, 14/17) than those with PD-1 negative expression. The 3-year survival rate of patients with positive and negative expression of PDL-1 was 48.78 % (20/41) and 61.29 % (19/31), respectively. Discussion The present results demonstrated that PD-1 and PDL-1 are abnormal in cancer tissue and PPB of LC patients. The combined detection of PD-1 and PDL-1 has diagnostic value for LC and evaluation value for the efficacy and prognosis of immunotherapy.

Abstract Objective The purpose of this study is to develop an animal model of Chronic Intermittent Hypoxia (CIH) and investigate the role of the TRPC5 channel in cardiac damage in OSAHS rats. Methods Twelve male Sprague Dawley rats were randomly divided into the CIH group and the Normoxic Control (NC) group. Changes in structure, function, and pathology of heart tissue were observed through echocardiography, transmission electron microscopy, HE-staining, and TUNEL staining. Results The Interventricular Septum thickness at diastole (IVSd) and End-Diastolic Volume (EDV) of rats in the CIH group significantly increased, whereas the LV ejection fraction and LV fraction shortening significantly decreased. TEM showed that the myofilaments in the CIH group were loosely arranged, the sarcomere length varied, the cell matrix dissolved, the mitochondrial cristae were partly flocculent, the mitochondrial outer membrane dissolved and disappeared, and some mitochondria were swollen and vacuolated. The histopathological examination showed that the cardiomyocytes in the CIH group were swollen with granular degeneration, some of the myocardial fibers were broken and disorganized, and most of the nuclei were vacuolar and hypochromic. Conclusion CIH promoted oxidative stress, the influx of Ca2+, and the activation of the CaN/NFATc signaling pathway, which led to pathological changes in the morphology and ultrastructure of cardiomyocytes, the increase of myocardial apoptosis, and the decrease of myocardial contractility. These changes may be associated with the upregulation of TRPC5.

ABSTRACT: The study aimed to investigate the distribution and expression of nesfatin-1 in Bactrian camels and its impact on adipocyte glucose metabolism. Polyclonal antibodies against a single antigenic epitope of NUCB2/nesfatin-1 protein were prepared. Nesfatin-1 expression was detected in various adipose tissues, including the hypothalamus, humps, stomach, duodenum, jejunum, ileum, cecum, colon, rectum, pancreas, liver, and abdomen, using Western blot and qRT-PCR. Glucose uptake levels, pyruvic acid content, and hexokinase and phosphofructokinase activities were measured in cultured 3T3-L1 preadipocytes treated with nesfatin-1 in a high glucose state using a non-radiofluorimetric assay. The results showed that nesfatin-1 was found in all Bactrian camel tissues, with higher adipose tissue and pancreas expression. However, qRT-PCR analysis revealed higher expression of nesfatin-1 mRNA in the abdominal fat and liver. After nesfatin-1 treatment, a significant decrease (p<0.05) was observed in glucose uptake levels, hexokinase, and phosphofructokinase activities in 3T3-L1 cells, with a significant increase (p<0.05) in their pyruvic acid content. These findings suggest that nesfatin-1 is expressed at high levels in the abdominal fat of Bactrian camels and significantly affects adipocyte glucose metabolism by regulating blood glucose levels, inhibiting adipocyte differentiation, and promoting lipid droplet hydrolysis to provide energy for the organism, which may relate to the Bactrian camel’s ability to adapt to harsh environments.

Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5’end or 3’end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5’ end or 3’ end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

Abstract Exogenous additives applied for cigar tobacco leaves fermentation played an important role in sensory quality of cigar. In this study, effects of additives including coffee and cocoa on the quality of cigar tobacco leaves were explored. The changes of sensory quality, conventional chemical components, nonvolatile organic acids, and aroma compositions in tobacco leaves were studied. Results showed that the richness, mellowness and matureness of aroma, as well as the fluentness and sweetness of smoke in cigar were improved with the introduction of coffee or cocoa. According to chemical composition analysis, fermentation with coffee or cocoa increased the contents of alkaloids and sugar in tobacco leaves, which endowed the tobacco a relatively good performance on the sweetness and aroma richness. Besides, the decrease of citric acid, as well as the increase of saturated fatty acid and aroma components were found with additives, which was beneficial to improve the mellowness and aroma richness of cigar. It was suggested that coffee and cocoa exhibited positive effects on the chemical composition, especially increased the contents of sugar, saturated fatty acids and aromatic components, thus improving the sensory quality of tobacco leaves.

Abstract Paper aims We investigate the drivers and barriers for the traceability digitalisation of the Australian construction supply chain. Originality There is a growing interest in the construction industry for embracing digital technologies. Nevertheless, the digital transition in construction industry is still slow, especially for addressing material traceability. Research method An exploratory-empirical study was conducted in which we performed the following steps: (i) definition of selection criteria; (ii) semi-structured interviews with 26 experts (academics, practitioners and stakeholders); and (iii) content analysis and propositions. Main findings Results allowed the identification of the most critical drivers and barriers for such traceability digitalisation, being consolidated in a conceptual framework that characterises the early and late adopters of digital technologies in the construction supply chain. Implications for theory and practice In theoretical terms, when considering the barriers/challenges, the degree to which the digital traceability's results are visible to the adopters seems to be an important issue, being able to impair the digitalisation of the construction supply chain. From a practical perspective, the more companies advance in the traceability digitalisation, the more aware they will become regarding its drivers/benefits and barriers/challenges. Nevertheless, some highly critical drivers/benefits and barriers/challenges were equally perceived by both early and late adopters. chain Nevertheless slow exploratoryempirical exploratory empirical steps i (i criteria ii (ii semistructured semi structured 2 academics, academics (academics stakeholders stakeholders) iii (iii propositions terms barrierschallenges challenges traceabilitys s issue perspective driversbenefits benefits

SUMMARY OBJECTIVE: This study aimed to explore the correlation between different body components and bone mineral density in healthy adults. METHODS: A total of 306 non-manual subjects, 161 males and 145 females, were selected from the physical examination center of our hospital from June to September 2019. They were divided into control group, overweight group, and obese group according to body mass index. The muscle mass and fat mass, body fat content, trunk fat mass, upper limb and thigh fat mass, bone density of femoral neck and lumbar vertebra, and bone mineral salt content of the whole body were measured by dual-energy X-ray absorptiometry. RESULTS: Body mass index, systolic blood pressure, diastolic blood pressure, femoral neck bone mineral density, bone mineral salt content, fat mass, muscle mass, upper limb fat mass, thigh fat mass, and trunk fat mass in the overweight group and obese group were all higher than those in the control group (P<0.05). The fat mass, muscle mass, upper limb fat mass, and trunk fat mass were positively correlated with the femoral neck bone mineral density, total lumbar vertebra bone mineral density, and bone mineral salt content (P<0.05). In addition, thigh fat mass was positively correlated with femoral neck bone mineral density and total lumbar spine bone mineral density, whereas body fat content was negatively correlated with bone mineral salt content. CONCLUSION: Body composition was related to bone mineral density and bone mineral salt content, and the correlation between different body composition indexes, and bone mineral density, and bone mineral salt content was different.

Abstract This article study the influences of fermented wheat germ on rats in terms of the blood glucose, insulin level, serum lipid level, cholesterol metabolism, triglyceride metabolism and enzyme activity on the basis of the high-fat rat model. High fat rats were fed for modeling, and then the serum and liver were collected after sacrifice. Total cholesterol (TC), triglyceride (TG), total superoxide dismutase (SOD), Superoxide dismutase (T-SOD), glutathione peroxidase (GSH-PX), Malonic dialdehyde (MDA), lecithin cholesterol acyltransferase (lecithin cholesterol), Acyltransferase (LCAT), LDL-C, blood glucose and insulin were measured. Fermented wheat germ can significantly increase the levels of insulin and blood glucose in high-fat rats. Fermented wheat germ for 60 days did not affect the levels of serum LDL-C and TG in high-fat rats, but could significantly reduce the level of serum TC. Fermented wheat germ for 60 days did not affect the activities of serum GSH-Px, T-SOD, LCAT and T-SOD, MDA and total lipase in high-fat rats, but it could significantly reduce the activity of serum MDA and increase the activity of GSH-PX in liver. Fermented wheat germ could reduce the protein expression of CYP7A1, induced p-AMPK protein expression, but had no effect on HMGR. Fermented wheat germ can significantly reduce the level of serum cholesterol in high-fat model rats by AMPK signaling pathway, and affect some cholesterol metabolism and triglyceride metabolism related enzyme activities to a certain extent.

Abstract The cigar market is growing rapidly in China. However, insufficient aroma value and quality, as well as confused subject fragrance were found in cigar tobacco leaves (CTLs), which has greatly restricted the development of Chinese cigar. In this study, several new and effective additives, including coffee, cocoa, ginger, cumin, and rhodiola rosea, were screened out for facilitating the fermentation process. Significant improvements on the aroma and sensory quality of CTLs were detected. The above-mentioned additives can increase the contents of total sugar, alcohols, alkenes, ketonic and acid aroma components in tobacco leaves. Besides, the content of representative aroma component, such as neophytadiene, increased by 1~2 times. Moreover, abundant new aroma components were introduced into CTLs. As a result, the performances on aroma richness, aroma and smoke characteristics, as well as aftertaste and combustion of CTLs were enhanced. The findings provide a promising strategy for enhancing sensory quality of domestic CTLs and the flourishment of Chinese cigar.

Abstract Shewanella and Pseudomonas are considered to be the main spoilage bacteria for chilled fish. This work focused on the spoilage and adhesion ability of two spoilage bacteria (Shewanella spp. S-1 and Pseudomonas spp. P-1), and the adhesion inhibitory effects of Bacillus subtilis against the spoilage bacteria in large yellow croaker (Pseudosciaena crocea). We aimed to develop a feasible solution to prolong the shelf life of large yellow croaker. The spoilage and adhesion characteristics of Shewanella spp. and Pseudomonas spp. strains were compared. It was found that Shewanella spp. induced more significant spoilage of large yellow croaker than Pseudomonas spp. at low temperature in vitro. In addition, Shewanella spp. demonstrated stronger adhesion to the intestinal mucus than Pseudomonas spp. in vitro. The results of a one-week feeding experiment showed that Shewanella was more likely to adhere to large yellow croaker intestines than Pseudomonas. The supplementation of B. subtilis strain BS08 effectively inhibited the proliferation of Shewanella and slowed the spoilage process of large yellow croaker.

Abstract This study aims to investigate the mechanism and effects of Fibrinogen-like protein 2 (FGL2) in myocardial ischemia/reperfusion injury in mice following sevoflurane anesthetic. Mice of SAP group were placed in box with oxygen and anesthetic gas (60 mg/kg, pentobarbital), 2.5% Sevoflurane was pumped into the box for 1 h. H9C2 cells were treated by 3% sevoflurane for 6 h and a mixture of 95% O2 + 5% CO2 for 24 h. Fgl2 mRNA expression was up-regulated in mice of I/R injury following sevoflurane. Fgl2 protein reduced HR, LVDP, dp/dtmax (+) and dp/dtmax (-), increased LVEDP levels, myocardial infarct size and AI in mice of I/R injury following sevoflurane. Fgl2 suppressed PPAR signaling pathway, and promoted ROS production in vivo or vitro model. The activation of PPAR signaling pathway reduced the function of Fgl2 in vivo and vitro model. Fgl2 might serve as a therapeutic target in the treatment of I/R injury following sevoflurane. We hope that our findings will pave a way for future therapies against I/R injury following sevoflurane.

Abstract Measuring red blood cell survival (RBCS) by a carbon monoxide breath test can help diagnose and analyze disease type and progression of anemia. In this study, we reported the application of RBCS in the differential diagnosis of thalassemia and iron deficiency anemia (IDA). A total of 233 patients were selected in this study, including 48 IDA, 60 thalassemia, and 125 healthy individual controls. The endogenous alveolar CO of each subject was measured by RBCS-01 red blood cell lifespanmeter to obtain the RBCS values. The mean RBCS for mild β-thalassemia, severe β-thalassemia, α-thalassemia, IDA and the control were 67.5±22.0, 31.3±13.9, 69.3±27.7, 78.2±28.2 and 114.3±33.8 days, respectively (P<0.05). RBCS values for thalassemia and IDA patients showed obvious shorter lifespan compared to healthy controls. The cutoff points for thalassemia, IDA and control were <72.5 and <83.5, respectively. RBCS showed a strong positive correlation to red blood cells (RBC) and hemoglobin (HGB) in thalassemia patients. In IDA patients, RBCS demonstrated a moderate positive correlation with HGB, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW). There were significant differences between RBCS in different types of thalassemia. RBCS by endogenous alveolar CO testing is a rapid and reliable method for the differential diagnosis of thalassemia and IDA.

Abstract Background: Phospholipase C-like 1 (PLCL1), a protein that lacks catalytic activity, has similar structures to the PLC family. The aim of this research was to find the function and underlying mechanisms of PLCL1 in fibroblast-like synoviocyte (FLS) of rheumatoid arthritis (RA). Methods: In this study, we first analyzed the expression of PLCL1 in the synovial tissue of RA patients and K/BxN mice by immunohistochemical staining. Then silencing or overexpressing PLCL1 in FLS before stimulating by TNF-α. The levels of IL-6, IL-1β and CXCL8 in FLS and supernatants were detected by Western Blot (WB), Real-Time Quantitative PCR and Enzyme Linked Immunosorbent Assay. We used INF39 to specifically inhibit the activation of NLRP3 inflammasomes, and detected the expression of NLRP3, Cleaved Caspase-1, IL-6 and IL-1β in FLS by WB. Result: When PLCL1 was silenced, the level of IL-6, IL-1β and CXCL8 were down-regulated. When PLCL1 was overexpressed, the level of IL-6, IL-1β and CXCL8 were unregulated. The previous results demonstrated that the mechanism of PLCL1 regulating inflammation in FLS was related to NLRP3 inflammasomes. INF39 could counteract the release of inflammatory cytokines caused by overexpression of PLCL1. Conclusion: Result showed that the function of PLCL1 in RA FLS might be related to the NLRP3 inflammasomes. We finally confirmed our hypothesis with the NLRP3 inhibitor INF39. Our results suggested that PLCL1 might promote the inflammatory response of RA FLS by regulating the NLRP3 inflammasomes.
