Objective: To evaluate the validity and reliability of the Chinese version of the Balanced Time Perspective Scale (BTPS) in college students. Methods: In sample 1 (n = 500), the Chinese version of the BTPS was administered, followed by item analysis and exploratory factor analysis. In sample 2 (n=722), the BTPS was tested for criterion validity, and the Zimbardo Time Perspective Inventory (ZTPI), Utrecht Work Engagement Scale-Student (UWE-S), and Index of Well-Being (IWB) were used as criterion measures. Confirmatory factor analysis was conducted. Sample 3 (n = 102) was selected for a retest after a three-week interval. Results: The Chinese version of the BTPS consisted of 27 items, including two dimensions naming past and future. Additionally, confirmatory factor analysis showed that the two-factor model was good fitted (x²/df = 3. 10, CFI = 0. 92, TLI = 0. 91, SRMR = 0. 05, RMSEA = 0.05). Criterion validity testing revealed significant positive associations between the scores of BTPS and those of ZTPI, UWE-S, and IWB. (ICC=0.59, 0. 70, 0. 68, 0. 51, Ps <0.001). The Cronbach's a coefficient for the BTPS was 0.95, while the Cronbach's a coefficients for the past and future dimensions were 0.92 and 0.93. The test-retest reliabilities of the BTPS scale and its past and future dimensions were 0.85, 0.80, and 0. 84. Conclusion: The Chinese version of the Balanced Time Perspective Scale exhibits good validity and reliability in assessing the time perspectives of college students [ABSTRACT FROM AUTHOR]

To investigate the radiosensitivity effect of radioresistant nasopharyngeal carcinoma cell line CNE ‐ 2R after overexpressing miR‐486‐5p. Methods microRNA(miRNA) sequencing and RT‐qPCR were used to detect the expression level of miR‐ 486‐5p in the parent cell line CNE2 and the radioresistant cell line CNE‐2R. CNE‐2R cells were infected with miR‐486‐5p overexpress‐ ion and negative control lentivirus, which were defined as CNE‐2R‐Mimics group and CNE‐2R‐NC group, respectively. CCK‐8 assay and Clonogenic assay were used to detect the proliferation ability and the viability of cells irradiated with different dose of (0 Gy, 2 Gy, 4 Gy, 6 Gy, 8 Gy) X‐ray. The cell apoptosis was detected by Annexin V‐APC/7‐AAD double stain assay. Results miRNA sequencing and RT ‐qPCR results showed that the level of miR ‐486‐5p in cell line CNE ‐2R was significantly lower than that in parent cell line CNE2. CCK‐8 assay revealed that the cell proliferation of CNE‐2R cells overexpressing miR‐486‐5p in CNE‐2R‐Mimics group was decreased compared with that in the CNE‐2R‐NC group after 48 h, 72 h and 96 h culture (all P<0.05). After the cells were irradiated with 2 Gy, 4 Gy, 6 Gy and 8 Gy irradiation, the survival fraction of CNE‐2R‐Mimics group was lower than that of the CNE‐2R‐NC group (all P<0.05), with the largest difference in the 8 Gy dose (t=30.152, P<0.001). Flow cytometry analysis indicated that the apoptosis rate of the CNE‐2R‐Mimics group was higher than that of CNE‐2R‐NC group at the irradiation dose of 0 Gy and 8 Gy (all P<0.05), and the difference of apoptosis rate under the irradiation dose of 8 Gy was more significant (t=14.945, P<0.001). The Clonogenic assay revealed that the clone formation fraction of the CNE‐2R‐Mimics group was lower than that of the CNE‐2R‐NC group under different doses, in which the radiobiological parameters D0, Dq, and the survival fraction in irradiation of 2 Gy in CNE‐2R‐Mimics group were lower than that of the CNE‐2R‐NC group (all P<0.05). Conclusions The nasopharyngeal carcinoma radioresistant cell line CNE‐2R overexpressing miR‐486‐5p may increase radiosensitivity by inhibiting cell proliferation and promoting apoptosis.

Due to the complexity of the liver region in abdominal images and the limitations of traditional segmentation methods, there are still many challenges in the field of liver segmentation. Aiming at the shortcomings of the existing segmentation network in the global and local information processing of the liver area, a segmentation method of cyclic densely connected network that integrates more local features is designed. This method integrates the cyclic dense connection module and the local feature supplement module into the learning unit of the coding process, so that the coding unit integrates deep-level global information and more-scale local feature information. Finally, after the decoding process, the softmax function is used to output the segmentation results. On the Li TS data set, the method performed well in multiple evaluation indicators, with an accuracy of 95.1%. In addition, in the Data . 6 related experimental data set 7 is also proved that the method has good generalization performance. Experiments show that dense connections and more local information can make the performance of the liver segmentation model better. [ABSTRACT FROM AUTHOR]

Based on the Λ-type level system in quantum mechanics, a three-level Λ-type system model with double electric field driven by microwave is established. The differential equation of the detection field is derived by the system density matrix, and is simulated by four order Runge Kutta numerical method. The steady state absorption properties of the system are studied, the interaction field and the atomic energy level system are analyzed. The results show that when the detuning is zero, the detection field could present a slight oscillation, almost no absorption propagation; when the detuning is not zero, the intensity of the detection field decreases sharply with the inerease of detuning, and electromagnetically induced parency occurs. Therefore, the coherence theory is used to explore its physical mechanism. The strength of detection field will greatly decay as the detuning amount is nonzero. The calculation results implements the electromagnetic induction of transparent with the microwave fields and provide a clear information for related research. [ABSTRACT FROM AUTHOR]

In 2014, 206 single-spore isolates of Fusarium graminearum collected from seven districts in Hubei province were identified by morphology. Sensitivity of 100 randomly selected isolates to carbendazim, tebuconazole and prochloraz was assayed by using mycelium growth inhibition method, and the sensitivity baseline was established. The results showed that the EC50 values of carbendazim, tebuconazole and prochloraz to F. graminearum isolates were in the ranges of 0.115-0.705, 0.006-1.356 and 0.002-0.370 μg/mL, and mean values of 0.248, 0.181 and 0.040 μg/mL, respectively. The sensitivity distributions of the 100 isolates to these three fungicides all followed unimodal quasi-normal distribution , which indicated that the EC50 mean values could be used as the sensitivity baseline of F. graminearum in Hubei province to these three fungicides. Using 10 times of the mean EC50 value of each fungicide as the discriminatory dose, the sensitivity of F. graminearum in Hubei province was monitored from 2015-2016. The study showed that the average inhibition rates of carbendazim, tebuconazole and prochloraz to F. graminearum isolates were 100%, 85.14%, 82.35%, respectively, in 2015, and 100%, 76.67%, 73.62%, respectively, in 2016. In summary, F. graminearum isolates in Hubei province still wxhibit high sensitivity to carbendazim, tebuconazole and prochloraz, although the inhibition rates of tebuconazole and prochloraz were slightly decreased in 2016.

Objective: To find quorum sensing inhibitors (QSIs) from Chinese herbal medicine Magnolia officinalis and to evaluate its inhibitory activity. Method: Pseudomonas aeruginous QSIS-lasI biosensor was used to monitor quorumsensing inhibitory activity. The bioactive compound in M. officinalis with anti-QS activity was separated by a bioautographic TLC assay, preparative TLC, and HPLC analysis. Its structure was identified by spectroscopic analysis. The pyocyanin and rhamnolipid production were determined by spectrophotometric method and orcinol method, respectively. And the swarming motility was assayed on semisolid agar plates. The effect of mRNA of QS-regulated gene was measured by RT-PCR. Results: M. officinalis extract was found to inhibit QS-controlled gene expression in P. aeruginous QSIS-lasI Biosensor. The active compound was purified and identified as honokiol. Honokiol at sub-inhibitory concentrations inhibited the production of virulence factors, including pyocyanin, rhamnolipid and swarming motility. It significantly reduced the level of mRNA of QS-related genes (P<0.05). Conclusion: Honokiol is a new QS inhibitor, which could be a potential agent for the treatment of bacterial infections.
