Objective To investigate the effect of miR-495-3p targeting budding uninhibited by benzimidazoles(BUB1)on signal transducer and activator of transcription 3(STAT3)signaling pathway on biological behavior of esophageal cancer(EC)cells.Methods The differentially expressed genes in EC tissues and normal tissues were screened by the cDNA microarray technique.The differentially expressed genes were analyzed by bioinformatics methods.The target genes of miRNAs were predicted by the TargetScan database and verified by a dual luciferase gene reporter assay.KYSE150 cells were divided into blank control group,NC mimics group and miR-495-3p mim-ics group.The activity of KYSE150 cells were detected by the CCK-8 method.Cell cycle and apoptosis were meas-ured by flow cytometry.The expression of BUB1 mRNA was measured by real-time fluorescence quantitative reverse transcription polymerase chain reaction(RT-qPCR).The levels of BUB1,STAT3,phosphor(p)-STAT3,cyclin dependent kinase 1(CCNB1),cyclin dependent kinase 1(CDK1),B-cell lymphoma-2(Bcl-2),cysteinyl aspar-tate-specific proteinase-3(Caspase-3)and cysteinyl aspartate-specific proteinase-3(Caspase-9)were measured by Western blot.The migration and invasion abilities of the cells were measured by wound-healing and Transwell inva-sion assays.Results Differentially expressed genes were involved in biological processes,signaling pathways and network construction,which were mainly related to cell cycle.BUB1 is the key(Hub)gene,and BUB1 is the tar-get gene of miR-495-3p.In vitro experiments showed that overexpression of miR-495-3p could significantly inhibit the migration and invasion of EC cells and induce apoptosis and G2/M phase arrest.After treatment with overex-pression of miR-495-3p,the expression of Caspase-3 and Caspase-9 in EC cells increased significantly(P＜0.01),while the expression of Bcl-2,BUB 1,CCNB1,CDK1 and p-STAT3 decreased significantly(P＜0.01).Moreover,the STAT3 signaling pathway might play an important role in this process.Conclusion miR-495-3p may influence the biological behavior of esophageal cancer cells by down-regulating BUB 1-mediated STAT3 signaling pathway.

Objective To observe the effects of different frequencies of electroacupuncture on the degree of atrophy of quadriceps femoris in rabbits with anterior cruciate ligament(ACL)injury model;To explore the possible mechanisms of electroacupuncture in treating ACL injury.Methods Totally 24 New Zealand rabbits were randomly divided into blank group,model group,low-frequency electroacupuncture group and high-frequency electroacupuncture group,with 6 rabbits in each group.Except for the blank group,ACL injury models were established in the other groups.On the 7th day after modeling,the low-frequency electroacupuncture group and the high-frequency electroacupuncture group performed electroacupuncture treatment(continuous wave,frequency of 2 Hz and 100 Hz respectively,and left the needle in place for 20 min)at"Xuehai"and"Liangqiu"of the operation side,and the remaining groups were only grasped and immobilized,for 21 days.The mass ratio of the quadriceps femoris was calculated,the histopathological morphology of the quadriceps femoris tissue of the rabbits in each group was observed by HE staining,the expressions of NO,iNOS in quadriceps femoris tissue were detected by ELISA,the content of ROS in quadriceps femoris tissue was detected by fluorescent probe,the protein expressions of PERK,ATF6,IRE1,MuRF1,MAFbx in quadriceps femoris tissue were detected by Western blot.Results Compared with the blank group,the quadriceps femoris muscle mass ratio of the model group rabbits was significantly reduced(P<0.01),with irregular arrangement of muscle cells,accompanied by swelling and atrophy,significant interstitial edema,and extensive inflammatory infiltration,the contents of NO,iNOS and ROS in quadriceps femoris tissue significantly increased(P<0.01),while the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly increased(P<0.01).Compared with the model group,the quadriceps femoris muscle mass ratio in the low-frequency and high-frequency electroacupuncture groups significantly increased(P<0.01),with regular arrangement of muscle cells,improved swelling and atrophy of cells,and reduced interstitial edema and inflammation,the contents of NO,iNOS and ROS in quadriceps femoris tissue were significantly reduced(P<0.01),and the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly decreased(P<0.01).Moreover,the low-frequency electroacupuncture group had better effects than the high-frequency electroacupuncture group(P<0.05).Conclusion Different frequencies of electroacupuncture intervention in ACL injury rabbits can better delay the degree of quadriceps femoris atrophy,and its mechanism may be related to reducing the expressions of oxidative metabolites NO,iNOS,ROS,and reducing the expressions of endoplasmic reticulum stress-related proteins PERK,ATF6,IRE1 in quadriceps fermoris,which in turn inhibit the expressions of quadriceps atrophy factors MuRF1,MAFbx,and delaying the degradation of quadriceps muscle proteins.The effect of low-frequency electroacupuncture is superior to the high-frequency electroacupuncture.

Objective:To evaluate the feasibility of using MRI-only simulation images for dose calculation of both photon and proton radiotherapy for nasopharyngeal carcinoma cases.Methods:T 1-weighted MRI images and CT images of 100 patients with nasopharyngeal carcinoma treated with radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2020 to December 2021 were retrospectively analyzed. MRI images were converted to generate pseudo-CT images by using deep learning network models. The training set, validation set and test set included 70 cases, 10 cases and 20 cases, respectively. Convolutional neural network (CNN) and cycle-consistent generative adversarial neural network (CycleGAN) were exploited. Quantitative assessment of image quality was conducted by using mean absolute error (MAE) and structural similarity (SSIM), etc. Dose assessment was performed by using 3D-gamma pass rate and dose-volume histogram (DVH). The quality of pseudo-CT images generated was statistically analyzed by Wilcoxon signed-rank test. Results:The MAE of the CNN and CycleGAN was (91.99±19.98) HU and (108.30±20.54) HU, and the SSIM was 0.97±0.01 and 0.96±0.01, respectively. In terms of dosimetry, the accuracy of pseudo-CT for photon dose calculation was higher than that of the proton plan. For CNN, the gamma pass rate (3 mm/3%) of the photon radiotherapy plan was 99.90%±0.13%. For CycleGAN, the value was 99.87%±0.34%. The gamma pass rates of proton radiotherapy plans were 98.65%±0.64% (CNN, 3 mm/3%) and 97.69%±0.86% (CycleGAN, 3 mm/3%). For DVH, the dose calculation accuracy in the photon plan of pseudo-CT was better than that of the proton plan.Conclusions:The deep learning-based model generated accurate pseudo-CT images from MR images. Most dosimetric differences were within clinically acceptable criteria for photon and proton radiotherapy, demonstrating the feasibility of an MRI-only workflow for radiotherapy of nasopharyngeal cancer. However, compared with the raw CT images, the error of the CT value in the nasal cavity of the pseudo-CT images was relatively large and special attention should be paid during clinical application.

Objective To investigate the infection of Chlamydia pneumoniae and mycoplasma pneumoniae in adults and their association with atherosclerosis,and to provide theoretical guidance for the prevention of such diseases. Methods A case-control study was used to collect 362 patients who were diagnosed with atherosclerosis from January 2019 to December 2021 in Department of Sichuan Bazhong Central Hospital, and 370 cases who were admitted to the hospital during the same period of physical examination without any cardiovascular disease were selected as the control group, and whole blood samples of the two groups of study subjects were collected, and the infection of Chlamydia pneumoniae and mycoplasma pneumoniae was detected by PCR. Results The infection rate of Chlamydia pneumoniae was 35.49%, the infection rate of mycoplasma was 40.37%, and the co-infection rate was 11.37%；The infection rate of Chlamydia pneumoniae in the control group was 12.04%, the infection rate of mycoplasma was 15.83%, and the coinfection rate was 3.14%, and the difference between the two groups was statistically significant ( χ²=10.926, P=0.023). The effects of mycoplasma, chlamydia, and co-infection on atherosclerotic patients have sex differences, mainly manifested as higher infection rates in men; In addition, the effects of mycoplasma, chlamydia, and co-infection on atherosclerosis patients varied by age, mainly in the 55-70 years age group (P<0.05). Multivariate logistic regression results showed that Chlamydia pneumoniae infection was a risk factor for atherosclerosis (OR=1.303, 95%CI: 1.043-1.677) in the whole population, and chlamydia pneumoniae (OR=1.472, 95% CI: 1.037-1.556), mycoplasma (OR=2.003, 95%CI: 1.637-3.842) and co-infection in men (OR=1.937, 95%CI: 1.380-2.184) were risk factors for atherosclerosis, while co-infection in women (OR=1.699, 95%CI: 1.263-1.765) was a risk factor for atherosclerosis. Conclusion Chlamydia pneumoniae and mycoplasma infection are risk factors for atherosclerosis, and their impact on male groups is greater, and more attention needs to be paid to them.
