AIM: To examine whether Akt signal pathway proteins, including Akt, NF-?B and I?B?, are activated in kidney tissue of murine chronic graft-versus -host disease (GvHD) lupus nephritis in vivo , and whether prednisone suppres ses activation of them. METHODS: Akt activity and phosphorylated I?B? were detected by Weste rn-blot. Activation of NF-?B was detected by electropheretic mobilit y shift assay (EMSA). RESULTS: Activity of Akt, NF-?B and phosp horylated I?B ? were significantly increased in kidney tissue of murine chronic graft-versus -ho st disease (GvHD) in 8th week and 12th week after monocell injection, respective ly. However, they were no significant elevation in 16th week, when compared with controls. Prednisone treatment significantly prevented the increase in serum an ti-dsDNA antibody level, urinary protein excretion and glomerular cell prolif eration in GvHD mice, indicating the beneficial effects of prednisone on t his model. Prednisone also significantly suppressed the increase in the activities o f glomerular Akt, NF-?B and phosphorylated I?B?. CONCLUSION: T his study provides t he first evidence of marked increase in glomerular Akt-NF-?B signal pathway act ivities in murine chronic graft-versus-host disease lupus nephritis. The benefic ial effect of prednisone on this lupus nephritis model may be partially mediated by the suppression of abnormal Akt- NF-?B activation.

Objective:
This study amis to evaluate the effect of resilience group counseling based on Achieving Success Everyday(ASE) group counseling model on mental health promotion of junior high school students.
Methods:
An experimental design of 2 (experimental group/control group)×3(pre-test/post-test/follow-up test) was adopted to conduct resilience group counseling for junior high school students in a school in southern Xinjiang (8 weeks, once a week, each activity lasts for 60-90 min), followed by a detailed analysis of intervention effect.
Results:
After intervention, scores of resilience, goal focus, emotional control, family support, interpersonal assistance, core self-evaluation, coping styles and positive coping in intervention group increased significantly(t=8.93, 3.78, 6.62, 3.17, 6.13, 5.18, 4.01, 2.91, P<0.01). The scores of mental health and negative coping significantly decreased (t=-4.24, -3.01, P<0.01) and was lower than control group(t=-2.58, -3.11, P<0.05). The scores of resilience, goal focus, interpersonal assistance, core self-evaluation, coping styles and positive coping were significantly higher than those of the control group(t=3.88, 2.84, 3.18, 4.19, 3.68, 2.49, P<0.01). The results of the follow-up test showed that the scores of resilience and goal concentration, emotional control, positive cognition, family support, interpersonal assistance, core self-evaluation and positive coping were still significantly higher than those of the pretest(t=5.69, 3.50, 2.26, 2.80, 2.64, 4.13, 3.39, 2.13, P<0.05), and the scores of mental health were still significantly lower than the pretest(t=-4.62, P<0.01).
Conclusion
Mental resilience group counseling based on ASE model can effectively improve students’ mental health level, and at the same time, it shows positive effect on improving core self-evaluation and coping styles.

The thyroid function test is universally used for the evaluation of thyroid function. However, there are factors other than endocrine diseases, such as special physiological conditions, interference in laboratory measurement, or disorders in other systems that should be taken into consideration. When encountering thyroid function test results that are not in line with clinical manifestation, a comprehensive evaluation is essential for a correct and timely diagnosis. We presented a case of a significant rise in serum total triiodothyronine(TT 3) secondary to multiple myeloma. Through case studies and literature review, we intended to provide clinicians with experience for better interpretation of abnormal thyroid function test results.

Objective:
To develop a convolution neural network (CNN) model to classify multi-sequence MR images of the prostate.
Methods:
ResNet18 convolution neural network (CNN) model was developed to classify multi-sequence MR images of the prostate. A deep residual network was used to improve training accuracy and test accuracy. The dataset used in this experiment included 19 146 7-sequence prostate MR images (transverse T1WI, transverse T2WI, coronal T2WI, sagittal T2WI, transverse DWI, transverse ADC, transverse PWI), from which a total of 2 800 7-sequence MR images was selected as a training set. Three hundred and eighty eight 7-sequence MR images were selected as test sets. Accuracy was used to evaluate the effectiveness of ResNet18 CNN model.
Results:
The classification accuracy of the model for transverse DWI, sagittal T2WI, transverse ADC, transverse T1WI, and transverse T2WI was as high as 100.0% (44/44,52/52), and the accuracy for transverse PWI was also as high as 96.7% (116/120). The accuracy for coronal T2WI was 77.5% (31/40). 0.8% (1/120) of transverse PWI was incorrectly assigned to transverse T2WI, and 2.5% (3/120) incorrectly assigned to sagittal T2WI. 15.0% (6/40) of coronal T2WI was incorrectly assigned to transverse T2WI, and 7.5% (3/40) to sagittal T2WI.
Conclusion
The experimental results show the effectiveness of our deep learning method regarding accuracy in the prostate multi-sequence MR images detection.
