Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Objective To explore the comparative study of constructing prediction models for muscle invasive of bladder cancer based on different machine learning algorithms combined with MRI radiomic.Methods A total of 187 bladder cancer patients who underwent MRI examination and were confirmed by pathology were retrospectively selected.Patients were randomly divided into a training set and a test set in a 7∶3 ratio.The patients were divided into muscle invasive bladder cancer(MIBC)group and non-muscle invasive bladder cancer(NMIBC)group according to the surgical pathology results.Tumor volume of interest(VOI)was outlined on the images of T2 WI,diffusion weighted imaging(DWI),and apparent diffusion coefficient(ADC),and the radiomic features were extracted by A.K software,and dimensionality reduction was performed using the maximum relevance minimum redundancy(mRMR)algorithm combined with least absolute shrinkage and selection operator(LASSO).Six machine learning algorithms,including K-nearest neighbor(KNN),decision tree(DT),support vector machine(SVM),logistic regression(LR),random forest(RF),and explainable boosting machine(EBM)were used to construct the radiomic model and calculate the corresponding area under the curve(AUC),accuracy,sensitivity,and specificity,respectively.Results Six machine learning algorithms,including KNN,DT,SVM,LR,RF,and EBM were used to construct the radiomic model,and the AUC values for predicting MIBC in the training set were 0.863,0.838,0.853,0.866,0.977,0.997,and in the test set were 0.748,0.833,0.860,0.868,0.870,0.900.Among them,the MRI radiomic model constructed based on EBM had the highest predictive efficacy for MIBC,with AUC values,accuracy,sensitivity and specificity of 0.997,0.977,0.957 and 0.981 in the training set,and 0.900,0.877,0.800,and 0.894 in the test set,respectively.Conclusion Multiple machine learning algorithms combined with MRI radiomic to construct models have good predictive efficacy for MIBC,and the model constructed based on EBM shows the highest predictive value.

Objective:To compare the clinical efficacy between robot-assisted and free-hand percutaneous cannulated screwing (PCS) in the treatment of femoral neck fractures in the middle-aged and young patients.Methods:A retrospective study was conducted to analyze the clinical data of 53 patients with femoral neck fracture who had been treated with PCS from May 2020 to May 2022 at Department of Traumatic Surgery, Maoming Hospital Affiliated to Southern Medical University. In the robot group of 25 patients subjected to robot-assisted PCS, there were 11 males and 14 females with an age of (48.2 ± 11.9) years; in the free-hand group of 28 patients subjected to free-hand PCS, there were 13 males and 15 females with an age of (48.5 ± 9.8) years. The 2 groups were compared in terms of operation time, intraoperative bleeding, intraoperative guide drills, intraoperative fluoroscopy frequency, fracture union time, Harris hip score at the last follow-up and postoperative complications. Postoperative imaging examination was performed to evaluate distribution accuracy of the cannulated screws in the femoral neck (deviation between the screws and the femoral neck axis, parallelism between the screws and distance between the screws and the neck cortex).Results:There was no statistically significant difference between the robot and free-hand groups in the general clinical data before operation, showing comparability ( P>0.05). The robot group showed significantly shorter operation time [(32.7 ± 4.8) min], significantly less intraoperative bleeding [(14.6 ± 4.8) mL], significantly less intraoperative guide drillings [(3.5 ± 0.7) times] and significantly less intraoperative fluoroscopy frequency [(7.9 ± 1.4) times] than the free-hand group [(56.9 ± 11.3) min, (27.0 ± 7.3) mL, (9.1 ± 1.8) times and (16.3 ± 6.0) times)] (all P<0.05). Postoperative imaging showed that the deviation between the screws and the femoral neck axis was 4.4° ± 1.1° on the anteroposterior X-ray film and 3.2° ± 0.8° on the lateral X-ray film, the parallelism between the screws 4.9° ± 0.8° on the anteroposterior X-ray film and 3.0° ± 0.7° on the lateral X-ray film, and the distance between the screws and the femoral neck cortex (10.4 ± 2.7) mm in the robot group, all significantly smaller than those in the free-hand group [10.5° ± 2.8°, 4.9° ± 1.1°, 12.1° ± 4.0°, 5.1° ± 1.3°, and (15.4 ± 3.2) mm] (all P<0.05). All the 53 patients were followed up for (22.2 ± 8.5) months. All fractures got united. The fracture union time in the robot group [(20.6 ± 4.6) weeks] was insignificantly shorter than that in the free-hand group [(23.7 ± 7.7) weeks] ( P>0.05). At the last follow-up, the Harris hip score in the robot group [(88.6 ± 5.6) points] was significantly higher than that in the free-hand group [(84.8 ± 6.3) points] ( P<0.05). Follow-ups revealed 2 cases of internal fixation loosening, 1 case of screw head cutting and 1 case of femoral head necrosis in the free-hand group but none of such complications in the robot group. Conclusion:In the treatment of femoral neck fractures in the middle-aged and young patients, compared with free-hand PCS, robot-assisted PCS shows advantages of shorter intraoperative time, less bleeding, less fluoroscopic radiation, higher accuracy of screw placement, a lower incidence of postoperative complications and better functional recovery of the hip joint.

Objective: To investigate the recurrence of pulmonary tuberculosis patients 5 years after successful treatment in Hengyang City, Hunan Province, and to analyze its influencing factors. Methods: The data of pulmonary tuberculosis patients who were successfully treated in Hengyang City in 2014 were collected through the tuberculosis management information system. The recurrence of pulmonary tuberculosis was defined as the endpoint, and all patients were observed for five consecutive years. Factors affecting recurrence of pulmonary tuberculosis were identified using Kaplan-Meier estimates, log-rank test and multivariable Cox proportional hazards regression analysis. Results: A total of 6 626 patients with successfully treated pulmonary tuberculosis were included, including 4 961 males and 1 665 females, with a median age of 54 years. There were 536 cases with recurrence of pulmonary tuberculosis within five years, with a 8.09% cumulative proportion of recurrence and annual recurrence rate of 1.75 per 100 person-years. Multivariable Cox proportional hazards regression analysis showed that men ( HR=1.592, 95%CI: 1.256-2.019 ), age of 40 years and greater ( age of 40 to 59 years, HR=7.025, 95%CI: 1.739-28.377; age of 60 years and greater, HR=8.175, 95%CI: 2.024-33.023), farmers ( HR=1.379, 95%CI: 1.070-1.778 ), retreatment ( HR=6.398, 95%CI: 5.163-7.929 ) and positive etiology ( HR=1.255, 95%CI: 1.042-1.511 ) were risk factors for five-year recurrence of pulmonary tuberculosis among successfully-treated patients. Conclusions High recurrence rate is found among pulmonary tuberculosis patients within five years after successful treatment in Hengyang City. There is a high risk of pulmonary tuberculosis recurrence among male, etiologically positive, retreated farmers at ages of 40 years and older, and targeted interventions are recommended.

Purpose: This study was aimed to investigate long-term survivals and toxicities of early-stage nasopharyngeal carcinoma (NPC) in endemic area, evaluating the role of chemotherapy in stage II patients. Materials and Methods: Totally 187 patients with newly diagnosed NPC and restaged American Joint Committee on Cancer/ International Union Against Cancer 8th T1-2N0-1M0 were retrospectively recruited. All received intensity-modulated radiotherapy (IMRT)±chemotherapy (CT) from 2001 to 2010. Results: With 15.7-year median follow-up, 10-year locoregional recurrence-free survival, distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were 93.3%, 93.5%, 92.9% and 88.2%, respectively. Multivariable analyses showed cervical lymph nodes positive and pre-treatment prognostic nutritional index ≥ 52.0 could independently predict DMFS (p=0.036 and p=0.011), DSS (p=0.014 and p=0.026), and OS (p=0.002 and p < 0.001); Charlson comorbidity index < 3 points could predict DSS (p=0.011); age > 45 years (p=0.002) and pre-treatment lactate dehydrogenase ≥ 240 U/L (p < 0.001) predicted OS. No grade 4 late toxicity happened; grade 3 late toxicities included subcutaneous fibrosis (4.3%), deafness or otitis (4.8%), skin dystrophy (2.1%), and xerostomia (1.1%). No differences on survivals were shown between IMRT+CT vs. IMRT alone in stage II patients, even in T2N1M0 (p > 0.05). Unsurprising, patients in IMRT+CT had more acute gastrointestinal reaction, myelosuppression, mucositis, late ear toxicity, and cranial nerve injury (all p < 0.05) than IMRT alone group. Conclusion Superior tumor control and satisfying long-term outcomes could be achieved with IMRT in early-stage NPC with mild late toxicities. As CT would bring more toxicities, it should be carefully performed to stage II patients.

With the development of organ transplantation in clinical practice, allograft pathology has been constantly developing and advancing. The convening of Banff conference on allograft pathology and the establishment of Banff classification on allograft pathology (Banff classification) are pivotal milestones in the development of international allograft pathology. Since then, Banff classification on pathological diagnosis of various transplant organs have been continually updated and improved. Ultrastructural pathological observation by electron microscope plays an irreplaceable role in the early diagnosis of antibody-mediated rejection, recurrent disease and de novo disease of renal allograft. Early detection and rational treatment help to maintain the long-term survival of renal allograft and reduce the failure of renal allograft. In this article, the basic definition of electron microscope and the ultrastructural pathological diagnosis, the research history and main progress on electron microscope diagnosis on Banff classification for renal allograft pathology were introduced, and typical pathological changes, specific terminology and diagnostic criteria of electron microscope diagnosis on renal allograft biopsy were summarized, aiming to provide reference for clinical and basic research of organ transplantation.
