Objective@#To observe the effect of dynamic and static combination of Wuqinxi on the psychological state and prefrontal oxygenated hemoglobin of female college students with subliminal depression (SD), so as to provide a high quality reference for optimizing their interventional measures.@*Methods@#A total of 72 female college students with SD in their third year of two semesters in the 2021-2022 academic year of Chongqing Second Normal University were randomly divided into a control group, an observation group 1, and an observation group 2. The control group received routine psychological intervention once a week, 20 minutes/time, while the observation group 1 received Wuqinxi exercise twice a day for about 30 minutes on the basis of the control group. The observation group 2 received a combination of dynamic and static Wuqinxi exercise on the basis of the control group, Wuqinxi dynamic exercise combined with Wuqinxi exercise guided imagination training about 20 minutes/time. All three groups received 12 weeks of intervention. Observe the Chinese version of the Hamilton Depression Scale (HAMD-24), Subthreshold Depression Scale (STDS), and Symptom Checklist-90 (SCL-90) before and after intervention, and collect serum γ aminobutyric acid (GABA) and plasma adrenocor ticotropic hormone (ACTH), and the concentration of oxyhemoglobin (Oxy Hb) in the prefrontal lobe were detected by functional near infrared spectroscopy (fNIRS).@*Results@#The results showed that the HAMD-24 and STDS scores of the two groups (11.33±1.29, 53.08±2.31) were lower than those of the control group and observation group 1 (18.27± 2.02 , 73.60±4.05; 15.19±1.92, 64.58±2.69), with statistically significant differences ( F=8.64, 11.85, P <0.05). Observing that the six dimensions of somatization, interpersonal, depression, anxiety, hostility psychoticism in the SCL-90 scale were lower in the two groups than in the other two groups ( F=3.68, 9.83, 10.37, 5.85, 3.05, 7.46, P <0.05). The plasma ACTH levels in the observation group were lower than those in the other two groups, while the peak concentration of Oxy Hb was higher than those in the other two groups ( F =3.27, 6.08, P <0.05). The serum GABA levels were higher than those in the control group, and there was no difference compared to the observation group 1 ( P >0.05).@*Conclusion@#The combination of dynamic and static Wuqinxi training can improve the psychological state of female college students with subthreshold depression, alleviate the depressive symptoms,possibly through increase of prefrontal oxygenated hemoglobin.

OBJECTIVE@#To propose a framework that combines sinogram interpolation with unsupervised image-to-image translation (UNIT) network to correct metal artifacts in CT images.@*METHODS@#The initially corrected CT image and the prior image without artifacts, which were considered as different elements in two different domains, were input into the image transformation network to obtain the corrected image. Verification experiments were carried out to assess the effectiveness of the proposed method using the simulation data, and PSNR and SSIM were calculated for quantitative evaluation of the performance of the method.@*RESULTS@#The experiment using the simulation data showed that the proposed method achieved better results for improving image quality as compared with other methods, and the corrected images preserved more details and structures. Compared with ADN algorithm, the proposed algorithm improved the PSNR and SSIM by 2.4449 and 0.0023 when the metal was small, by 5.9942 and 8.8388 for images with large metals, and by 8.8388 and 0.0130 when both small and large metals were present, respectively.@*CONCLUSION@#The proposed method for metal artifact correction can effectively remove metal artifacts, improve image quality, and preserve more details and structures on CT images.

Objective@#To analyze risk factors of anastomotic leakage after McKeown'sesophagectomy.@*Methods@#The clinical data of 635 esophageal cancer patients, who underwent McKeown's esophagectomy at Cancer Hospital of Chinese Academy of Medical Sciences from January 2012 to December 2015, were retrospectively analyzed. The risk factors of cervical anastomotic leakage were identified through analysis of medical history, surgical procedure, tumor characteristics and vascular calcification.@*Results@#Among all the 635 patients, anastomotic leakage occurred in 111 (17.5%)patients. Univariate analysis showed that the American Society of Anesthesiologists (ASA) risk class, prior thoracic surgery, upper digestive tract ulcer, COPD, hypertension, peripheral vascular disease, renal insufficiency, FEV1% predicted, DLCO% predicted, duration of surgery and calcification of descending aorta, celiac trunk and left postceliac arteries were associated with a statistically significant increase in risk of cervical anastomotic leakage (P<0.05 for all). Logistic regression analysis showed that ASA risk class, peripheral vascular disease, renal insufficiency and calcification of descending aorta and celiac trunk were independent risk factors of cervical anastomotic leakage after McKeown's esophagectomy (P<0.05 for all).@*Conclusions@#ASA risk class, peripheral vascular disease, renal insufficiency, calcification of descending aorta and celiac trunk are independent risk factors of cervical esophageal anastomotic leakage after McKeown's esophagectomy.
