Abstract
In 2019, the rate of primary tooth caries rate among 1 598 preschool children in Shinan District and Shibei District of Qingdao was 59.4%. The multivariate logistic regression model showed that compared with children ≤ 2 years old with history of iron deficiency anemia (IDA), suffering IDA, breastfeeding to 2 years old and no tooth melanin, children ≤ 2 years old without history of IDA, not suffering IDA, breastfeeding to less than 2 years old and heavy tooth melanin had a lower risk of primary tooth caries, with OR (95%CI) values about 0.328 (0.197-0.549), 0.354 (0.208-0.603), 0.636 (0.437-0.926) and 0.301 (0.143-0.635), respectively.

Abstract
Mechanical deformation of human skin provides essential information about human motions, muscle stretching, vocal fold vibration, and heart rates. Monitoring these activities requires the measurement of strains at different levels. Herein, we report a wearable wide-range strain sensor based on conducting polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). A bioinspired bilayer structure was constructed to enable a wide-range strain sensing (1%~100%). Besides, hydrogel was chosen as the biological- and mechanical-compatible interface layer with the human skin. Finally, we demonstrated that the strain sensor is capable of monitoring various strain-related activities, including subtle skin deformation (pulse and phonation), mid-level body stretch (swallowing and facial expressions), and substantial joint movement (elbow bending).

Abstract
1.The role of acetate in lipogenesis of chickens remains largely unknown. This trial investigated the effect of sodium acetate (SA) on chicken fat metabolism via in vivo and in vitro experiments.2.The results indicated that supplementation of SA (1.0 g/kg feed) showed marginal to moderate stimulation on the area of the abdominal fat cells and triglyceride (TG) content in liver and adipose tissues. It increased the transcription of some genes involved in fat synthesis and deposition, but did not affect free fatty acid receptor 2 (FFAR2) expression in either liver or abdominal fat.3. In cultured hepatocytes treated with 0.01 mM to 5 mM SA, although mRNA levels of ACC1, PPAR, SREBP-1 c, and FFAR2 were upregulated with SA at certain concentrations, TG content and protein expression of lipogenic genes and FFAR2 were not altered at any dosages. In adipogenic differentiation of preadipocytes, high concentrations of SA (5 mM) exhibited significant increments in TG content and accumulated fat droplets, associated with stimulated transcription of FAS, LPL, AD, FABP4, and FFAR2, as well as elevated protein expression of FABP4 and FFAR2.4. The results showed that adipocytes were more sensitive to acetate than hepatocytes in chickens. While acetate played a minor role in hepatic fat metabolism, it promoted lipogenesis in adipocytes via FFAR2 with the involvement of FAS, LPL, and FABP4.

Abstract
Objective: To evaluate the diagnostic value of bronchoalveolar lavage fluid pathogen detection combined with cryptococcal antigen test(CrAg) for pulmonary cryptococcosis(PC). Methods: A retrospective case analysis was performed on non-acquired immunodeficiency syndrome patients admitted to Ninghai First Hospital for suspected PC from January 2018 to December 2019. Fifty-nine patients were included. Sixteen cases (8 males and 8 females) were diagnosed with PC, aged from 18 to 76 years[an average age of (52±14) years], while 43 cases were diagnosed as having Non-PC. All patients had undergone both serum CrAg test and BALF pathogen detection(cultures and direct examination) combined with BALF-CrAg test. The sensitivity and specificity of the combined method of BALF was evaluated, and a parallel comparison of the diagnostic efficiencies of the two methods were made. Results: Of the 16 confirmed PC cases, serum CrAg tests were positive in 11 and negative in 5 cases, while the combined method showed that 14 were positive and 2 were negative. Compared with the clinical final diagnosis, the sensitivity, specificity, positive predictive value and negative predictive value showed that the serum CrAg tests were 68.8% (11/16), 97.7% (42/43), 91.7% (11/12), 89.3% (42/47) respectively, versus 87.5% (14/16), 100.0% (43/43), 100% (14/14), 95.6% (43/45) by the combined method of BALF. The results displayed no statistical difference between the two diagnostic methods (P =1.000). Among the 5 initially serum CrAg-negative cases, 4 were later confirmed as proven PC via the combined method of BALF and the other one by percutaneous lung biopsy. Conclusion: The combined method of BALF pathogen detection with BALF-CrAg showed a similar statistical efficiency rate for diagnosing pulmonary cryptococcosis compared with serum CrAg tests. It may serve as an efficient diagnosis method for PC cases with negative serum CrAg tests.

Abstract
Surgery remains the foundation of curative therapy for non-metastatic breast cancer, but many patients do not undergo surgery. Evidence is limited regarding this population. We sought to assess factors associated with lack of surgery and overall survival (OS) in patients not receiving breast cancer surgery. Retrospective cohort study of patients in the US National Cancer Database treated in 2004-2016. The dataset comprised 2,696,734 patients; excluding patients with unknown surgical status or stage IV, cT0, cTx, or pIS, metastatic or recurrent disease resulted in 1,192,294 patients for analysis. Chi-square and Wilcoxon rank-sum tests were used to assess differences between groups. OS was analyzed using the Kaplan-Meier method with a Cox proportional hazards model performed to assess associated factors. In total 50,626 (4.3%) did not undergo surgery. Black race, age >50 years, lower income, uninsured or public insurance, and lower education were more prevalent in the non-surgical cohort; this group was also more likely to have more comorbidities, higher disease stage, and more aggressive disease biology. Only 3,689 non-surgical patients (7.3%) received radiation therapy (RT). Median OS time for the non-surgical patients was 58 months (3-year and 5-year OS rates 63% and 49%). Median OS times were longer for patients who received chemotherapy (80 vs 50 (no-chemo) months) and RT (85 vs 56 (no-RT) months). On multivariate analysis, age, race, income, insurance status, comorbidity score, disease stage, tumor subtype, treatment facility type and location, and receipt of RT were associated with OS. On subgroup analysis, receipt of chemotherapy improved OS for patients with triple negative (HR 0.66, 95% CI 0.59-0.75, P < 0.001) and HER2+ (HR 0.74, 95% CI 0.65-0.84, P < 0.001) subgroups while RT improved OS for ER+ (HR 0.72, 95% CI 0.64-0.82, P < 0.001) and favorable-disease (ER+, early-stage, age >60) (HR 0.61, 95% CI 0.45-0.83, P = 0.002) subgroups. Approximately 4% of women with breast cancer do not undergo surgery, particularly those with more aggressive disease and lower socioeconomic status. Despite its benefits, RT was underutilized. This study provides a benchmark of survival outcomes for patients who do not undergo surgery and highlights a potential role for use of RT.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of cullin 4A (CUL4A) on promoting the proliferation and inhibiting the apoptosis of cervical cancer (CC) cells by regulating the nuclear factor-kappa B (NF-κB) signaling pathway. PATIENTS AND METHODS The protein expressions of CUL4A and NF-κB in 75 CC tissues were detected through immunohistochemistry. The correlation between the expressions of the two proteins in CC tissues was analyzed via Spearman's correlation test. Meanwhile, the prognostic significance of CUL4A expression for CC patients was analyzed by Kaplan-Meier curve. CUL4A small interfering ribonucleic acid (siRNA) was transfected into CC cells (HeLa) to downregulate the expression level of CUL4A. Subsequently, the effects of CUL4A on the proliferation and apoptosis of HeLa cells were detected by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry, respectively. Finally, the effect of CUL4A on the activity of the NF-κB signaling pathway was analyzed through quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). RESULTS The protein expressions of CUL4A and NF-κB in CC tissues were significantly higher than those in normal tissues (p<0.01). The results of the survival curve showed that the prognosis of CC patients with highly expressed CUL4A is poor (p<0.001). Meanwhile, lowly expressed CUL4A protein significantly inhibited the proliferation and promoted the apoptosis of HeLa cells (p<0.01). QRT-PCR results indicated that the relative messenger RNA (mRNA) expression levels of downstream genes of the NF-κB signaling pathway were significantly lower in CC cells than those in the control group (p<0.001). In addition, CUL4A expression was positively correlated with NF-κB expression in CC (p<0.001). CONCLUSIONS CUL4A promotes the invasion of CC cells through the NF-κB signaling pathway.

Abstract
OBJECTIVE In recent years, long non-coding RNAs (lncRNAs) have emerged for regulating the development, as well as progression in colorectal cancer (CRC), which assists in finding new targets for CRC treatment. A previous study indicated that INHBA-AS1 promotes oral squamous cell progression by sponging miR-143-3p. However, the exact function possessed by lncRNA INHBA-AS1 in CRC development remains unclear. PATIENTS AND METHODS The expression level of INHBA-AS1 in CRC tissues and cell lines was determined by qRT-PCR. The functional role of INHBA-AS1 in CRC was investigated by a series of in vitro assays. RNA immunoprecipitation (RIP), bioinformatics analysis was utilized to explore the potential mechanisms of INHBA-AS1. RESULTS The present study identified INHBA-AS1 as a kind of lncRNA with high expression in CRC tissues and cells. Functionally, NHBA-AS1 downregulation in CRC cells suppressed CRC cell proliferation as well as colony formability. Mechanistically, INHBA-AS1/miR-422a/AKT1 established the ceRNA network to regulate MMP-2, -7, -9 expressions that participated the modulation of CRC progression. CONCLUSIONS In summary, LncRNA INHBA-AS1 contributes to CRC progression through AKT1 pathway, and provides a new mechanism to regulate CRC development, as well as a potential target for treating CRC.

Abstract
OBJECTIVE To investigate whether anti-hypertrophic memory exists after regression of exercise-induced physiological myocardial hypertrophy (PMH) and explore the contribution of sympathetic activation to hypertrophic memory formation. OBJECTIVE Seventy-two mice were randomized equally into 6 groups, including sedentary sham-operated group, exercise hypertrophic preconditioning (EHP) + sham operation group, bisoprolol (an adrenergic β1 receptor blocker) + EHP + sham operation group (biso+Exe+Sham group), sedentary group with transverse aortic constriction (TAC) (Sed+TAC group), EHP+ TAC group (Exe+TAC group), and bisoprolol+EHP+TAC group (biso+Exe+TAC group). The mice in the EHP groups were subjected to 3 weeks of swimming training, and in the bisoprolol groups, bisoprolol was administered by gavage once daily from two days before till the end of the training. One week after the training, TAC or sham surgery was performed. Echocardiography and hemodynamic measurements were performed to evaluate cardiac function of the mice, and the myocardial tissues were examined histologically to detect cardiac remodeling. OBJECTIVE Compared with the sedentary group, the mice receiving 3 weeks of swimming training had significantly increased heart weight to body weight ratio (HW/BW), HW to tibia length ratio (HW/TL), and the cross-sectional area of the cardiomyocytes (P < 0.05). One week after the training, exercise-induced PMH rapidly diminished and both HW/BW and HW/TL recovered the baseline levels. Treatment with bisoprolol obviously prevented the occurrence of PMH. Four weeks after TAC, the left ventricular posterior wall thickness, HW/BW, HW/TL, left ventricular end diastolic pressure and cross-sectional area of cardiomyocytes were all significantly lower (P < 0.05) while the left ejection fraction and maximal change rate of left ventricular pressure were significantly higher (P < 0.05) in Exe + TAC group than in Sed + TAC group. No significant difference was found in these parameters between biso + Exe + TAC group and Sed + TAC group. OBJECTIVE Anti-hypertrophic memory exists even after the regression of exercise-induced PMH, which may be attributed to the activation of sympathetic nervous system during exercise.

Abstract
OBJECTIVE To explore the factors affecting the survival of patients with advanced gastric cancer and establish a reliable predictive model of the patients' survival outcomes. OBJECTIVE We retrospectively collected the clinical data from patients with advanced gastric cancer treated in our department between January, 2015 and December, 2019. Univariate survival analysis was carried out using Kaplan-Meier method followed by multivariate Cox regression analysis to identify the factors associated with the survival outcomes of the patients. The R package was used to generate the survival rates, and a nomogram was established based on the results of multivariate analysis. The calibration curves and C-index were calculated to determine the predictive and discriminatory power of the model. The performance of the nomogram model for predicting the survival outcomes of the patients was evaluated using receiver- operating characteristic (ROC) curve analysis and decision curve analysis (DCA). OBJECTIVE Univariate analysis showed that the number of metastatic sites, the number of treatment lines received, disease control rate (DCR) and progression-free survival (PFS) time following first-line treatment, and surgical treatment in first-line treatment were significantly correlated with the survival time of the patients (P < 0.05). Multivariate Cox regression analysis showed that surgical treatment, number of treatment lines, PFS time following first-line treatment and peritoneal metastasis, as independent prognostic factors, were significantly correlated with the patients' survival (P < 0.05). The C-index of the nomogram was 0.785 (95%CI: 0.744-0.826) for overall survival of the patients. The calibration curves showed that the actual survival rate of the patients was consistent with the predicted survival rate. The time-dependent AUC and DCA demonstrated that the nomogram had a good performance for predicting the survival outcomes of patients with advanced gastric cancer. OBJECTIVE Peritoneal metastasis is associated with s shorter overall survival time of patients with advanced gastric cancer, while a PFS time following first-line treatment of more than 7.0 months and third-line and posterior-line treatments are related with a longer survival time. Systematic treatment including elective surgery can improve the survival outcomes of the patients. The nomogram we established provides a reliable prognostic model for evaluating the prognosis of patients with advanced gastric cancer.

Abstract
OBJECTIVE Studies have demonstrated that long non-coding RNAs (lncRNAs) are important in the development and prognosis of prostate cancer. The aim of this study was to investigate the functions and mechanism of lnc-SNHG14 in prostate cancer. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) or Western blot (WB) were performed to detect mRNA expressions of SNHG14 and miR-5590-3p, and the protein levels of Yin Yang-1 (YY1) in prostate cancer tissues, adjacent tissues, and cancer cell lines. The correlation analysis was used to analyze the correlations between SNHG14, miR-5590-3p, and YY1. Kaplan-Meier survival analysis was used to analyze the overall survival for prostate cancer patients. Cell Counting Kit-8 (CCK-8) assay was performed to measure cell proliferation ability and flow cytometry assay was used to detect cell apoptotic rate. Besides, transwell assay was used to measure cell invasion ability. In addition, WB was performed to measure protein expressions in prostate cancer cell lines. Finally, Luciferase reporter assay was performed to verify the binding sites between SNHG14 and miR-5590-3p, miR-5590-3p, and YY1. RESULTS The results showed that SNHG14 was significantly increased in prostate cancer tissues and prostate cancer cell lines, which were related with advanced stage and poor diagnosis for prostate cancer patients. MiR-5590-3p was reduced in prostate cancer tissues and cell lines, which were negatively correlated with SNHG14. YY1 was found to be increased in prostate cancer tissues, which was negatively correlated with miR-5590-3p and positively correlated with SNHG14. Furthermore, SNHG14 knockdown inhibited cell proliferation, invasion, and promoted cell apoptosis in DU145 cells. In addition, protein expressions of Cyclin D1, Bcl-2, and N-cadherin were repressed, and the levels of Bax, Cleaved Caspase-3, and E-cadherin were increased. Besides, miR-5590-3p inhibition promoted cell proliferation and invasion, and inhibited apoptosis in DU145 cells. Importantly, Luciferase reporter assay proved that SNHG14 could directly sponge with miR-5590-3p, which could bind with YY1 and regulate the functions of cancer cell. Finally, we proved that SNHG14 regulated cell proliferation, cell apoptosis, and invasion via miR-5590-3p/ YY1 axis in prostate cancer. CONCLUSIONS Above all, we found that SNHG14 was increased in prostate cancer patients, which was related with future diagnosis for prostate cancer patients. Of note, we discovered that SNHG14 could promote cell proliferation, invasion, and repress cell apoptosis via miR-5590-3p/YY1 axis in prostate cancer, which might provide a new target for treating prostate cancer.

Abstract
OBJECTIVE To analyze the species, abundance and structure differences of intestinal flora between patients with type 2 diabetes mellitus (T2D) and healthy individuals and explore the correlation between intestinal flora changes and T2D. OBJECTIVE We collected a total of 133 clinical fecal samples from 78 healthy individuals and 55 patients with T2D. Hiseq2500 was used for high-throughput sequencing of the V3+V4 regions of the 16S rRNA gene. Usearch and QIIME were used for data splicing and filtering, classification and species annotation. The Alpha diversity index and Beta diversity index of the samples were analyzed using R language data packets to compare the richness and diversity of the sample flora. The flora differences were compared between the two groups and the disease marker flora was screened after correction of the relevant factors. PICRUST software was used to predict the function of different flora. OBJECTIVE There was significant difference in the intestinal flora diversity between the two groups. Cluster analysis showed that Fimicutes and Bacteroidetes were the dominant species at the phylum level. LefSe analysis showed that significant differences in the relative abundance between the two groups in 2 phyla, 3 classes, 3 orders, 4 families and 10 genera. After correction for the influence of related factors, the markers of T2Drelated bacteria groups were identified, including Bifidobacterium, Bifidobacteriales, Bifidobacteriaceae, Actinobacteria, Bacilli, Lactobacillales, Lactobacillaceae and Lactobacillus. On this basis, analysis of KEGG metabolic pathways of the differential flora revealed significant differences in 36 KEGG metabolic pathways between the two groups, and the citric acid cycle, lipopolysaccharide biosynthesis and other metabolic pathways were all up-regulated in T2D group. OBJECTIVE The composition and abundance of intestinal flora were different between T2D group and the normal group, and T2D group showed the characteristics of ecological imbalance.

Abstract
In the paper, synthesis of chitosan-based hydrogels modified with Aloe vera juice is presented. The novelty of the research was a combination of hydrogel materials with properties beneficial in viewpoint of their use as modern wound dressings and Aloe vera juice supporting the wound healing process. Hydrogels have been obtained via UV radiation. The impact of the amount of the crosslinking agent as well as the introduction of the Aloe vera juice into the hydrogel matrix has been determined. Performed measurements involved analysis of the swelling ability, characteristics of the surface roughness, determining the release profile of Aloe vera and the contact angles of hydrogels. Furthermore, the analysis of the dehydration process of the polymer membrane, investigations on the cytotoxicity of hydrogels via MTT reduction assay and the neutral red uptake assay as well as the studies on the pro-inflammatory activity have also been performed. It was proved that the addition of Aloe vera juice improves the hydrophilic properties of the materials (e.g. contact angle changed from 82.5° to 73.0°). Next, the use of 25% more of the crosslinker resulted even in the increase of the contact angle by 86%. Modified hydrogels showed higher swelling properties even by 15% than unmodified materials. Furthermore, obtained hydrogels show an ability to release Aloe vera - after 5 h approx. 80% of this additive has been released in an acidic environment. Tested materials do not exhibit cytotoxic properties, the addition of Aloe vera results in an improvement of the viability of L929 murine fibroblasts and, importantly, these materials show lower pro-inflammatory activity than the positive control. Performed investigations allow to state that obtained materials show a great application potential.

Abstract
Chigger mites is a group of arthropods and some of them are vectors of scrub typhus. As a common synanthropic rodent species, the Brown rat (Rattus norvegicus) often harbors lots of ectoparasites including chigger mites. According to some "data mining" strategies, the present study took the advantage of the abundant original data from a long-term field ecological investigation between 2001 and 2015 to make a detailed analysis of chigger mites on R. norvegicus in Yunnan Province, Southwest of China. From 18 of 33 investigated counties, only 1414 chigger mites were collected from 1113 Brown rats with relatively low infestations. The 1414 individual chigger mites were identified as comprising 61 species, 11 genera and 2 subfamilies of the family Trombiculidae with a high species diversity (S=61, H'=3.13). Of 61 mite species, there were four main species, Walchia ewingi, Ascoschoengastia indica, W. koi and A. rattinorvegici, which accounted for 44.41% of the total mites. All the chigger mites were of aggregated distribution among different individuals of R. norvegicus. The Brown rats in the outdoor habitats harbored much more individuals and species of chigger mites with a higher mean abundance (MA=1.46) and mean intensity (MI=12.53) than in the indoor habitats (P<0.05). The overall infestation of the rats was significantly higher in the mountainous landscapes than in the flatland landscapes (P<0.001). The species similarity (Css) of the mites on the male and female rats reached 64.44% with sex biased infestations. The male rats harbored more species and individuals of the mites than the female rats. The adult rats harbored more species and individuals of the mites than the juvenile rats. The species abundance distribution of the mites was successfully fitted by Preston's lognormal model with ŝ(R)=15e-[0.31(R-1)]2 (α=0.31, R2=0.95). On the basis of fitting the theoretical curve by Preston's model, the total mite species on R. norvegicus was estimated to be 86 species, and 25 rare mite species were missed in the sampling field investigation. The curve tendency of the species-plot relationship indicates that R. norvegicus have a great potential to harbor many species of chigger mites, and more species of the mites would be collected if more rats are sampled.

Abstract
We propose a feasible, high-efficiency scheme of primary terahertz (THz) radiation source through manipulating electronic structure (ES) of a metallic film by targeted-designed DC-fields configuration. The DC magnetic field is designed to be of a spatially inhomogeneous strength profile, and its direction is designed to be normal to the film, and the direction of the DC electric field is parallel to the film. Strict quantum theory and numerical results indicate that the ES under such a field configuration will change from a 3D Fermi sphere into a highly-degenerate structure whose density-of-state curve has pseudogap near Fermi surface. Wavefunctions' shapes in this new ES are space-asymmetric, and the width of pseudogap near Fermi surface, as well as magnitudes of transition matrix element, can be handily controlled by adjusting parameter values of DC fields. Under available parameter values, the width of the pseudogap can be at milli-electron-volt level (corresponding to THz radiation frequency), and the magnitude of oscillating dipole can be at [Formula: see text]-level. In room-temperature environment, phonon in metal can pump the ES to achieve population inversion.

Abstract
The amount of mental effort we invest in a task is influenced by the reward we can expect if we perform that task well. However, some of the rewards that have the greatest potential for driving these efforts are partly determined by factors beyond one's control. In such cases, effort has more limited efficacy for obtaining rewards. According to the Expected Value of Control theory, people integrate information about the expected reward and efficacy of task performance to determine the expected value of control, and then adjust their control allocation (i.e., mental effort) accordingly. Here we test this theory's key behavioral and neural predictions. We show that participants invest more cognitive control when this control is more rewarding and more efficacious, and that these incentive components separately modulate EEG signatures of incentive evaluation and proactive control allocation. Our findings support the prediction that people combine expectations of reward and efficacy to determine how much effort to invest.
