Abstract
Objective: To explore the relationship between expression levels of CLOCK mRNA and protein and the clinical characteristics of patients with nasopharyngeal carcinoma. Methods: The frozen tissue specimens from 33 patients with nasopharyngeal carcinoma in the Affiliated Tumor Hospital of Guizhou Medical University from 2018 to 2019 were collected. Seventeen cases of tissue specimens from patients with nasopharyngeal chronic inflammation in the Affiliated Hospital of Guizhou Medical University in 2019 were collected. From 2008 to 2014, 68 cases of formalin-fixed paraffin-embedding (FFPE) nasopharyngeal carcinoma tissue and 37 cases of FFPE nasopharyngeal chronic inflammation tissue were collected from the Affiliated Tumor Hospital of Guizhou Medical University. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blot (WB) were used to detect the mRNA and protein expression levels of CLOCK. The nasopharyngeal carcinoma cells including CNE1, CNE2, 5-8F and the normal nasopharyngeal epithelial cell NP69 were cultured. qRT-PCR was used to detect the expression level of CLOCK mRNA in each cell line at the time points of ZT2, ZT6, ZT10, ZT14, ZT18 and ZT22. The cosine method was used to fit the rhythm of CLOCK gene in nasopharyngeal carcinoma. The protein expression of CLOCK protein was detected by using immunohistochemical method in 68 cases of nasopharyngeal carcinoma and 37 cases of nasopharyngeal chronic inflammation tissue. Survival was analyzed by Kaplan-Meier method and Log rank test, and the influencing factors was analyzed by Cox regression model. Results: The expression levels of CLOCK mRNA in CNE1, CNE2 and 5-8F cells (0.63±0.07, 0.91±0.02 and 0.33±0.04, respectively) were lower than that in NP69 cell (1.00±0.00, P<0.05). The expression levels of CLOCK protein in CNE1, CNE2 and 5-8F cells (0.79±0.06, 0.57±0.05 and 0.74±0.10, respectively) were lower than that of NP69 cells (1.00±0.00, P<0.05). The expressions of CLOCK mRNA in nasopharyngeal carcinoma cells including CEN1, CNE2, 5-8F and normal nasopharyngeal epithelial cell NP69 were different at different time points, with temporal fluctuations. The fluctuation periods of CLOCK mRNA in CNE1, CNE2, 5-8F, and NP69 cells were 16, 14, 22 and 24 hours, respectively. The peak and trough times were ZT10: 40 and ZT18: 40, ZT10 and ZT3, ZT14: 30 and ZT3: 30, ZT12: 39 and ZT0: 39, respectively. CLOCK mRNA and protein expression levels in nasopharyngeal carcinoma tissues (0.37±0.20 and 0.20±0.26, respectively) were lower than those in nasopharyngeal chronic inflammation tissues (1.00±0.00 and 0.51±0.41, respectively, P<0.05). The 1, 3, and 5-year survival rates of patients in the CLOCK protein high expression group (CLOCK protein expression level ≥ 0.178) were 96.2%, 92.1%, and 80.1%, respectively, which were higher than those in the low expression group (CLOCK protein expression level <0.178, 92.9% , 78.6% and 57.1%, respectively, P=0.009). The 1, 3, and 5-year progression-free survival (PFS) rates of patients in the CLOCK protein high expression group were 96.2%, 87.8%, and 87.7%, respectively, which were higher than those in the low expression group (92.7%, 82.2%, and 70.8%, respectively, P=0.105). Compared with the low-expression group (100.0%, 96.9%, and 90.0%, respectively), the 1, 3, and 5-year recurrence-free survival rates of patients in the CLOCK protein high expression group (100.0%, 95.7%, and 95.7%, respectively) were not statistically significant (P=0.514). Compared with the low-expression group (92.7%, 82.2%, and 79.3%), the 1, 3, and 5-year survival rates without metastasis in the CLOCK protein high expression group (96.2%, 92.0%, and 92.0%, respectively) were not statistically significant (P=0.136). CLOCK protein expression and T stage were independent prognostic factors of overall survival (P<0.05). Conclusions: The expression of CLCOK is downregulated in the nasopharyngeal carcinoma cell and nasopharyngeal carcinoma tissues. Clock gene CLOCK is rhythmically expressed in the nasopharyngeal carcinoma cells and normal nasopharyngeal epithelial cells. Compared with normal nasopharyngeal epithelial cells, the fluctuation period of CLOCK in nasopharyngeal carcinoma cells is shortened. The overall survival of patients in the CLOCK protein high expression group is better than that of low expression group. The expression of CLOCK protein is an independent influencing factor for overall survival. CLOCK gene may be a potential tumor suppressor gene in the nasopharyngeal carcinoma.

Abstract
Objective: To investigate the time and characteristics of screen exposure, to analyze the risk factors affecting screen exposure in children aged 3 years and younger, and to provide scientific basis for the intervention of screen exposure in children. Methods: The data were collected by convenience sampling from 317 children for routine examination aged 0-36 months who visited the Department of Child Healthcare, Children's Hospital, Capital Institute of Pediatrics from December 2019 to December 2020. Self-designed questionnaires of the screen exposure were completed by the parents. The basic information, home nurture environment and screen exposure conditions were investigated. Children <18 months of age who used electronic devices and 18-36 months of age who spent more than 1 h/d on electronic devices were defined as with screen exposure. The differences between <18 and 18-36 months of age were compared by rank sum test. Chi-square test and multivariate Logistic regression were used to analyze the association between screen exposure and potential influential factors. Results: Among 317 children, 209 were boys and 108 girls, aged (28±10) months. There were 117 patients aged <18 months and 200 patients aged 18-36 months. Screen exposure time was 0.3 (0, 1.0) h/d and 1.2 (0.6, 2.0) h/d in children aged <18 months and aged 18-36 months, respectively (Z=-6.770, P<0.01). The proportion of screen exposure was 25.6% (30/117) and 49.0% (98/200) in two age groups, respectively. Logistic regression analysis disclosed that not being the first child (OR=3.81, 95%CI: 1.13-12.77, P=0.030), caregivers spending >1 h/d on electronic devices in front of their children (OR=7.39, 95%CI: 2.24-24.46, P=0.001), caregivers believing that screen exposure can promote early childhood development (OR=4.14, 95%CI: 1.26-13.52, P=0.019) were risk factors for children's screen exposure in <18 months of age. Caregivers spending >1 h/d on electronic devices in front of their children (OR=3.29, 95%CI: 1.78-6.08, P<0.01) was risk factor for children's screen exposure in 18-36 months of age. Mothers with bachelor's or higher degree (OR=0.19, 95%CI: 0.05-0.66, P=0.009; OR=0.35, 95%CI: 0.19-0.66, P=0.001), no television in living room (OR=0.11, 95%CI: 0.03-0.42, P=0.001; OR=0.45, 95%CI: 0.21-0.98, P=0.045) were protective factors for children's screen exposure in children <18 months and 18-36 months of age. Conclusions: Excessive screen exposure is common among children aged 3 years and younger. The exposure time increases with age, and is affected by several factors.

Abstract
Objective: To explore the method and plausibility of using free rectus abdominis flap (FRAF) to reconstruct the major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinoma. Methods: From 2007 to 2018 at No. 980 Hospital of Joint Logistic Supportive Force of People's Liberation Army of China, 13 patients with advanced carcinoma of nasal cavity and paranasal sinuses, including 11 males and 2 females, aged from 33 to 67 years, were treated with FRAF to repair the invasion of skull base, face and orbit. Based on adequate and meticulous preoperative evaluations on patients and tumors, complete resection of tumor bulks was performed. According to the sites, characters and extents of the defects, FRAF was introduced in different ways into reconstruction of major and complex defects in the craniofacial regions after resection of advanced sinonasal carcinomas, restoring the structure and contour of the craniofacial region. Results: Complete resection of tumors was achieved in all cases. For repairing the major and complex defects resulted from tumor ablation, FRAF graft was conducted in 13 patients with advanced sinonasal carcinomas. The recipient vessels were facial artery and vein in 9 cases, superficial temporal artery and vein in 4 cases. Vascular bridging with the external jugular vein was carried out in 2 cases who underwent submandibular neck dissections, in which facial artery and vein were used as recipient vessels. Free fibular flap was used along with FRAF in a case undergone bilateral maxillectomy. Pedicled galea capitis and periosteal flap were applied simultaneously in 3 cases with dura defects at the skullbase resulted from tumor resection. All flaps used in 13 cases survived uneventfully without major complications, with successful repair of defects, reconstruction of structures and restoration of contour of craniofacial regions. Conclusion: With adequate evaluation of resectability of tumors as well as nature and extent of defects after tumor removal, FRAF transplantation is an ideal method and strategy of choice for reconstructing the major and complex defects in craniofacial regions resulted from tumor ablation of advanced sinonasal carcinomas.

Abstract
BACKGROUND Endometrial lesions include endometrial cancer and inferior fibroids. Among them, endometrial cancer as a malignant tumor seriously endangers the life and health of patients. Ultrasonography is an important means of diagnosing female reproductive system diseases, and it is of critical value for the early diagnosis of endometrial cancer. However, different ultrasound inspection programs have achieved different results. It is of great significance to choose a suitable inspection program.
AIM To explore the diagnostic efficacy of different ultrasonic examination methods in clinical endometrial lesions.
METHODS The 140 patients with endometrial lesions who were treated in our hospital from April 2018 to October 2019 were used as the research subjects. All patients underwent transvaginal color ultrasound and transabdominal color ultrasound. We compared the diagnostic coincidence and image display effects of the two different examination methods, and the endometrial thickness, blood flow, uterine effusion and resistance index of different diseases were observed by transvaginal color ultrasound.
RESULTS The diagnostic coincidence rate of all types of diseases of transvaginal color ultrasound was significantly higher than that of transabdominal color ultrasound (P = 0.001, 0.005, 0.001 and 0.001). In addition, the excellent and good rate of image display of transvaginal color ultrasound was higher than that of transabdominal color ultrasound (P = 0.001). There were significant differences in endometrial thickness in patients with different types of endometrial lesions through the transvaginal color examination (P = 0.001). The incidence rate of uterine effusion in patients with endometrial carcinoma was significantly higher than that in patients with other types of endometrial lesions (P = 0.001), and the rate of the blood flow was the highest (P = 0.001). The comparison of blood flow resistance index indicated that the blood flow resistance index in endometrial cancer patients was the lowest, which shows that the difference was statistically significant (P = 0.001).
CONCLUSION The overall diagnostic efficacy of transvaginal color ultrasound in the clinical diagnosis of endometrial lesions is better than that of transabdominal color ultrasound, which held higher diagnostic coincidence rate and image display effect. There were significant differences in the thickness of the endometrium and the blood flow in different types of lesions.

Abstract
Objective: To investigate the characteristics of consonant among children with speech sound disorder (SSD) and to provide an empirical basis for the subsequent clinical evaluation and evidence-based intervention. Methods: In this retrospective research a total of 1 395 children diagnosed with SSD from the Language-Speech Clinic of the Department of Children Health Care, Children's Hospital, Capital Institute of Pediatrics from January 2007 to December 2018 were enrolled and underwent the phonological examination on the lexical level with picture naming, according to phoneme development in Chinese mandarin. The Chi-square trend test was applied to analyze the differences and trends of the proportion of consonant error subtypes in children of different age groups. The Chi-square test was conducted to compare the proportion of consonant error subtypes in different gender. Results: The 1 395 children diagnosed with SSD included 1 044 boys and 351 girls, with an age of (5.1±0.8) years. The occurrence of consonant errors in different locations of articulation was the highest for blade-alveolar /l/ (71.8%, 1 002/1 395) and the lowest for labial/b/(9.3%, 130/1 395). The occurrence of consonant errors of labial/p/f/, supra-dental/z/c/s/, blade-alveolar/t/l/, blade-palatal/ch/r/, velar/k/h/, and lingua-palatal/q/decreased with age (all P<0.05). The occurrence of consonant errors of labial/b/m/, supra-dental/z/c/, blade-alveolar/n/l/, blade-palatal/sh/, velar/h/, and lingua-palatal/x/were higher in boys than those in girls (10.3% (108/1 044) vs. 6.3% (22/351), 11.4% (119/1 044) vs. 6.0% (21/351), 64.8% (676/1 044) vs. 51.9% (182/351), 67.8% (708/1 044) vs. 59.8% (210/351), 16.7% (174/1 044) vs. 8.8% (31/351), 73.7% (769/1 044) vs. 66.1% (232/351), 58.0% (606/1 044) vs. 47.6% (167/351), 24.0% (251/1 044) vs. 14.2% (50/351), and 39.9% (417/1 044) vs. 27.6% (97/351); χ²=5.167, 8.533, 16.889, 7.447, 12.863, 7.412, 11.650, 14.900, and 17.099, all P<0.05). The error types of consonant were substitution, omission, and distortion. Omission was the main error type of blade-alveolar/l/(53.3%, 743/1 395), distortion was the main error type of velar/h/(11.8%, 165/1 395), and substitution was the main error type of all other consonants. Substitution with blade-palatal/ch/having the highest occurrence of error (60.2%, 840/1 395). Conclusions: The occurrence of the blade-alveolar/l/error is the highest in children with SSD, with boys demonstrating more serious articulation problems. The main error type of consonant is substitution, with blade-palatal/ch/having the highest occurrence of error. These results suggest the necessity of attending to preschoolers' articulation development. Phonological training targeting blade-alveolar/l/and blade-palatal/ch/should be carried out as early as possible.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the most direct and effective method for the diagnosis and treatment of biliary and pancreatic diseases. Compared with surgery, ERCP has the advantages of minimal trauma, shorter surgery time, fewer complications, and shorter hospital stay. Liver cirrhosis, as the advanced stage of liver disease, has reduced tolerance to surgical stresses, and complications such as hepatic encephalopathy, esophagogastric varices, and coagulation dysfunction may occur during the decompensated stage, which poses a challenge to ERCP, and thus increase the intraoperative risk and postoperative complications. This article reviews and discusses the indications, risk and control management of ERCP in patients with liver cirrhosis.

Methods: A total of 16 317 clinical samples and related data of cervical liquid-based thin-layer cell smears, which were obtained from July 2020 to September 2020, were collected from Southern Hospital, Guangzhou Huayin Medical Inspection Center, Shenzhen Bao'an People's Hospital(Group) and Changsha Yuan'an Biotechnology Co., Ltd. The TBS report artificial intelligence-assisted diagnosis system of cervical liquid-based thin-layer cytology jointly developed by Southern Medical University and Guangzhou F. Q. PATHOTECH Co., Ltd. based on deep learning convolution neural network was used to diagnose all clinical samples. The sensitivity,specificity and accuracy of both artificial intelligence-assisted diagnosis system and cytologists using artificial intelligence-assisted diagnosis system were analyzed based on the evaluation standard(2014 TBS). The time spent by the two methods was also compared. Results: The sensitivity of artificial intelligence-assisted diagnosis system in predicting cervical intraepithelial lesions and other lesions (including endometrial cells detected in women over 45 years old and infectious lesions) under different production methods, different cytoplasmic staining and different scanning instruments was 92.90% and 83.55% respectively, and the specificity of negative samples was 87.02%, while that of cytologists using artificial intelligence-assisted diagnosis system was 99.34%, 97.79% and 99.10%, respectively. Moreover, cytologists using artificial intelligence-assisted diagnosis system could save about 6 times of reading time than manual. Conclusions: Artificial intelligence-assisted diagnosis system for TBS report of cervical liquid-based thin-layer cytology has the advantages of high sensitivity, high specificity and strong generalization. Cytologists can significantly improve the accuracy and work efficiency of reading smears by using artificial intelligence-assisted diagnosis system.

Abstract
Objective: To determine whether amoxicillin had an effect on the enamel mineralization of SD rats. Methods: Eighteen SD rats were randomly divided into three groups. The rats in the control group were given distilled water. The rats in two experimental groups were administered 50 or 100 mg/kg amoxicillin by intragastric administration from day 3 to day 17 after birth. The general condition, the structure of liver and kidney, the enamel surface changes of mandibular first molars and incisors were observed. The changes of Ca/P ratio on enamel surface were analyzed by X-ray energy dispersive spectrometer (EDS). The surface morphology after phosphoric acid treatment was examined by scanning electron microscopy (SEM). Histological changes in the ameloblasts of mandibular incisors were analyzed by hematoxylin and eosin (HE) staining. Results: Compared with the control group, the general conditions as well as liver and kidney structures of SD rats in 50 and 100 mg amoxicillin groups had no significant differences. There was no obvious chalky changes on the first mandibular molars of SD rats in each group. All the incisors in 50 and 100 mg groups showed different degrees of chalkiness in the labial incisal 1/3 enamel. X-ray EDS analysis showed that the Ca/P ratios of occlusal and incisal 1/3 enamel in 50 and 100 mg groups (occlusal 1/3 of mandibular first molars: 1.51±0.03 and 1.52±0.02, incisal 1/3 of mandibular incisors: 1.46±0.01 and 1.43±0.01) was significantly lower than that in the control group (occlusal 1/3 of mandibular first molars: 1.67±0.41, incisal1/3 of mandibular incisors: 1.73±0.07) (P<0.05). However, there was no significant differences in the cervical 1/3 Ca/P ratio of mandibular first molars and incisors among the three groups (mandibular first molars: 1.56±0.04 for control group, 1.59±0.05 for 50 mg group and 1.57±0.04 for 100 mg group; incisors: 1.52±0.02 for control group, 1.47±0.01 for 50 mg group and 1.51±0.03 for 100 mg group) (P>0.05). SEM observation showed that the enamel rods of the first molars and incisors in the 50 and 100 mg group varied in size and arranged disorderly. The spaces between the enamel rods were larger than that in the control group and some areas even appeared large pits. HE staining showed that the gaps between ameloblasts in 50 and 100 mg groups were significantly wider than that in the control group. Conclusions: Intake of amoxicillin during the period of enamel development of SD rats might affect enamel mineralization.

Abstract
Objective: To analyze the long-term outcome of unoperated Ebstein's anomaly (EA) patients aged over 18 years, and to evaluate the related factor of outcomes. Methods: The data of 48 unoperated EA patients from March 2004 to December 2008 in the First Hospital of Tsinghua University, were analyzed. The clinical data of the patients were collected, and patients received regular echocardiography, ECG and chest X-ray examinations. Septal leaflet attachment ratio (SLAr) was calculated based on transthoracic echocardiography imagines. The patients were divided into 3 groups according to SLAr: SLAr<0.45 (n=18), 0.45≤SLAr≤0.60 (n=21) and SLAr>0.60 (n=9). Chest X-ray was used for measurement of cardiothoracic ratio (CTR). Kaplan Meier survival curve was used to calculate the long-term survival rate. Cox proportional hazards regression model was used to analyze the influencing factors of death. Results: There were 19 males, and the mean age at diagnosis was (21.3±11.1) years. Forty-two patients (87.5%) were complicated with arrhythmia, including W-P-W syndrome (n=4), supraventricular tachycardia (n=16), right bundle branch block (n=37), and atrial fibrillation (n=2). The mean duration of follow-up was (148.8±16.8) months, the follow-up rate was 100% with no loss-to-follow up. Nine cases (18.8%) died during follow-up: 6 cases (12.5%) died of cardiac origin, including 3 cases of heart failure, 1 case of arrhythmia, and 2 cases of sudden death; 1 case died of accident; 2 cases died from unknown causes. During the follow-up period, the survival rates were 17/18, 19/21 (90.5%) and 3/9 in the SLAr<0.45, 0.45≤SLAr≤0.60 and SLAr>0.60 group, respectively. According to Kaplan-Meier survival curve, the 5-year survival rates among the three groups were 100%, 100% and 78%, respectively. The 10-year survival rates among the three groups were 94%, 95% and 44%, respectively. Decreased activity tolerance and heart failure were found in 7 patients (6 patients in SLAr>0.60 group and 1 patient in 0.45≤SLAr≤0.60 group). Two patients had cerebrovascular embolism. There were 3 cases with tachyarrhythmia lasting more than 24 hours. Cox regression analysis showed that the risk of death was higher in patients with SLAr>0.60 than in patients with SLAr<0.45 (HR=12.375, 95%CI 1.692-22.146, P=0.015); the risk of death in patients with CTR≥0.65 was 1.306 times higher than that in patients with CTR<0.65 (HR=1.306, 95%CI 0.417-12.754, P=0.038). Conclusions: EA patients often combines with arrhythmia. For unoperated EA patients, SLAr>0.60 and CTR≥0.65 are risk factors of death. EA patients with arrhythmia should be actively treated with drugs or radiofrequency ablation.

Abstract
Exosomes are a kind of membrane vesicle with a diameter of 30-150 nm. It is formed by the budding of multiple vesicles in cells, which can fuse with the cell membrane and be released into the extracellular matrix. Adipose derived stem cells (ADSCs) have the potential of self-renewal and multi-directional differentiation. They can transport the active substance, regulate the inflammatory response, cell migration, proliferation, differentiation and angiogenesis via the action of paracrine exosomes, so as to enhance the ability of wound repair, promote wound healing, and inhibit the formation of scars. Chronic wounds refer to the wounds that can not reach the anatomic and functional integrity through the normal, orderly, and timely repair process, and the course of the wound healing is more than 4 weeks. At present, there are various treatment methods for chronic wounds, among which ADSCs, although showing a good application prospect, have some limitations due to ethical issues, while exosomes can avoid this problem. This article reviews the treatment of chronic wounds with ADSC exosomes.

Abstract
Objective: To investigate the biological function of miR-758-3p and the underlying mechanism in non-small cell lung cancer (NSCLC). Methods: miR-758-3p mimics was transfected to A549 NSCLC cells, miRNA control was used as a negative control, cells transfected with nucleolar and spindle associated protein 1 (NUSAP1)-overexpression vector indicated as NUSAP1 group, cells co-transfected with miR-758-3p mimics and NUSAP1-overexpression vector indicated as miR-758-3p mimics+ NUSAP1 group. The effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells were detected by cell counting kit-8 (CCK-8) and Transwell assays, respectively. Bioinformatics and dual luciferase reporter assay were used to predict and verify the target gene of miR-758-3p. Results: The expressions of miR-758-3p and NUSAP1 in A549 cells were significantly up-regulated at 24 hours after transfection with miR-758-3p mimics (P<0.05). Compared with the miRNA control group (1.15±0.06), the OD value of miR-758-3p mimic group (0.78±0.06) was significantly decreased at 72 hours after transfection (P<0.05). The number of migrated cells of miR-758-3p mimic group (119.04±11.49) was significantly lower than that of the control group (271.38±19.05) (P<0.05). The number of invaded cells of miR-758-3p mimic group (71.33±5.36) was significantly lower than the control group (164.30±8.11) (P<0.05). The result of dual-luciferase reporter assay showed that NUSAP1 was a direct target of miR-758-3p. Moreover, up-regulation of NUSAP1 abolished the inhibitory effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells. Conclusion: miR-758-3p inhibits the proliferation, migration and invasion of NSCLC cells by targeting NUSAP1.

Abstract
Objective: Surgical site infection (SSI) can markedly prolong postoperative hospital stay, aggravate the burden on patients and society, even endanger the life of patients. This study aims to investigate the national incidence of SSI following abdominal surgery and to analyze the related risk factors in order to provide reference for the control and prevention of SSI following abdominal surgery. Methods: A multicenter cross-sectional study was conducted. Clinical data of all the adult patients undergoing abdominal surgery in 68 hospitals across the country from June 1 to 30, 2020 were collected, including demographic characteristics, clinical parameters during the perioperative period, and the results of microbial culture of infected incisions. The primary outcome was the incidence of SSI within postoperative 30 days, and the secondary outcomes were ICU stay, postoperative hospital stay, cost of hospitalization and the mortality within postoperative 30-day. Multivariable logistic regression was used to analyze risk factors of SSI after abdominal surgery. Results: A total of 5560 patients undergoing abdominal surgery were included, and 163 cases (2.9%) developed SSI after surgery, including 98 cases (60.1%) with organ/space infections, 19 cases (11.7%) with deep incisional infections, and 46 cases (28.2%) with superficial incisional infections. The results from microbial culture showed that Escherichia coli was the main pathogen of SSI. Multivariate analysis revealed hypertension (OR=1.792, 95% CI: 1.194-2.687, P=0.005), small intestine as surgical site (OR=6.911, 95% CI: 1.846-25.878, P=0.004), surgical duration (OR=1.002, 95% CI: 1.001-1.003, P<0.001), and surgical incision grade (contaminated incision: OR=3.212, 95% CI: 1.495-6.903, P=0.003; Infection incision: OR=11.562, 95%CI: 3.777-35.391, P<0.001) were risk factors for SSI, while laparoscopic or robotic surgery (OR=0.564, 95%CI: 0.376-0.846, P=0.006) and increased preoperative albumin level (OR=0.920, 95%CI: 0.888-0.952, P<0.001) were protective factors for SSI. In addition, as compared to non-SSI patients, the SSI patients had significantly higher rate of ICU stay [26.4% (43/163) vs. 9.5% (514/5397), χ(2)=54.999, P<0.001] and mortality within postoperative 30-day [1.84% (3/163) vs.0.01% (5/5397), χ(2)=33.642, P<0.001], longer ICU stay (median: 0 vs. 0, U=518 414, P<0.001), postoperative hospital stay (median: 17 days vs. 7 days, U=656 386, P<0.001), and total duration of hospitalization (median: 25 days vs. 12 days, U=648 129, P<0.001), and higher hospitalization costs (median: 71 000 yuan vs. 39 000 yuan, U=557 966, P<0.001). Conclusions: The incidence of SSI after abdominal surgery is 2.9%. In order to reduce the incidence of postoperative SSI, hypoproteinemia should be corrected before surgery, laparoscopic or robotic surgery should be selected when feasible, and the operating time should be minimized. More attentions should be paid and nursing should be strengthened for those patients with hypertension, small bowel surgery and seriously contaminated incision during the perioperative period.

Abstract
Objective: To investigate the inhibitory effects of nucleolar and spindle associated protein 1 (NUSAP1) on lung cancer and the related mechanisms. Methods: A549 cells were transfected with NUSAP1 siRNA, the cell proliferation, migration and invasion, and apoptosis were detected by CCK8, Transwell and flow cytometry, respectively. Western blot was used to detect the expressions of apoptosis and AKT/mTOR signal pathway related proteins. Results: Compared with the negative control group, the proliferation [(0.610±0.058) vs (1.724±0.067), P<0.05], migration [(178.267±14.780) vs (272.464±36.232), P<0.05] and invasion [(73.527±6.617) vs (120.585±13.235), P<0.05] of NUSAP1 deleted A549 cells were significantly inhibited, while the apoptosis [(3.572±0.214)% vs (11.358±1.047)%, P<0.05] was significantly increased. The expressions of apoptosis related protein Bax and active-caspase 3 were increased (P<0.05), while the expressions of anti-apoptosis protein Bcl-2 and proliferation related protein P70, the phosphorylation levels of AKT and mTOR were reduced in NUSAP1 knockdown cells (P<0.05). Conclusion: NUSAP1 knockdown can inhibit the proliferation, migration and invasion, and promote the apoptosis of tumor cells through suppressing AKT/mTOR signaling pathway in lung cancer cells.

Abstract
OBJECTIVE To analyze the sequences of mitochondrial cytochrome C oxidase subunit I gene (COI) and 18S ribosomal RNA gene (18S rRNA), so as to identify the feasible DNA barcodes for 4 species of cheyletid mites and improve the DNA barcoding database for cheyletid mites. METHODS Cheyletid mite samples were collected from small-scale flour mills in Fuyang, Wuhu and Tongling cities of Anhui Province from May 2018 to July 2019, extracted and morphologically identified. Then, genomic DNA was extracted from a single cheyletid mite, and the COI and 18S rRNA gene sequences were obtained by PCR amplification, cloning and sequencing. The obtained sequences were aligned using the BLAST software. Multiple sequence alignment was done using the software ClustalX version 1.83 using the known gene sequences from cheyletid mites. The genetic distance was calculated using the software MEGA X, and the phylogenetic tree was created using the maximum likelihood method. RESULTS The DNA barcoding results of Cheyletus malaccensis, C. carnifex and Cheletomorpha lepidopterorum were consistent with the morphological identification, while no sequences pertaining to Eucheyletia reticulate were retrieved in the GenBank database. The proportions of A + T were 69.6% and 55.1% in the COI and 18S rRNA sequences of 4 cheyletid mites species, respectively, and the numbers of base substitutions were 137 and 46, respectively. There were 154 to 321 and 58 to 99 inter-species variation loci in the COI and 18S rRNA gene sequences of 4 cheyletid mites species, respectively, and the intra-species genetic distance was all 0.020 or less in the COI and 18S rRNA gene sequences of 4 cheyletid mites species, with inter-species genetic distance of 0.235 to 0.583 and 0.078 to 0.114, respectively. Phylogenetic analysis based on COI and 18S rRNA genes showed that all four species of cheyletid mites were clustered into a branch with a 100% supportive rate, which was consistent with the morphological identification. CONCLUSIONS Mitochondrial COI gene is superior to 18S rRNA gene as DNA barcodes for 4 species of cheyletid mites, which is more suitable to be used to investigate the phylogenetic relationship of at genus and species levels.

Abstract
Objective: To investigate the effect of occupational factor exposures on carotid atherosclerosis (CAS) in steel workers. Methods: A frequency matched case-control study was conducted by age and factory proportion. A total of 1 033 workers with carotid atherosclerosis diagnosed by ultrasonography examination from February to June 2017 were selected as case group, and 1 033 workers without carotid atherosclerosis indicated by physical examination at the same time were selected as control group. The basic information of the workers, such as diet pattern, lifestyle, serum biochemical index and occupation history, were collected. The effects of occupational hazards on carotid atherosclerosis were analyzed by univariate and multivariate logistic regression analyses. The combined effects of various occupational hazards on carotid atherosclerosis were evaluated by environmental risk score (ERS). Results: High temperature, noise, occupational stress and night shift days increased the risk of CAS. With the increase of cumulative high temperature and noise exposure, occupational stress and night shift days, the risk of CAS increased (trend text: χ(2)=37.53, P<0.01; χ(2)=16.98, P<0.01; χ(2)=13.93, P<0.01; χ(2)=5.59, P<0.05). After adjustment of covariates, compared with P(20) group, the risk of carotid artery in P(40), P(60), P(80) and P(100) groups were as follows: high temperature 1.61 (1.19-2.18), 1.69 (1.25-2.30), 1.84 (1.36-2.49), 2.43 (1.77-3.34); noise 1.70 (1.15-2.52), 1.68 (1.20-2.35), 1.80 (1.34-2.42), 2.23 (1.53-3.26); occupational stress 1.39 (1.04- 1.86), 1.41 (1.06-1.89), 1.45(1.09-1.95), 1.48 (1.10-1.98); night shift days 1.58 (1.08-2.33), 1.66 (1.12-2.47), 1.55 (1.04-2.31), 1.76 (1.17-2.64). The results of the environmental risk score showed that the risk of carotid atherosclerosis increased with the increase of ERS (ERS trend text χ(2)=51.61, P<0.01); RCS results showed that there was a linear relationship between ERS and CAS in steel workers(P<0.01). Linear dose-response relationship existed between ERS and CAS (nonlinear test P>0.05). Conclusions: High temperature, noise, occupational stress and night shift days were related to carotid atherosclerosis. Linear dose-response relationship existed between ERS and CAS in steel workers.

Abstract
Objective: To investigate the clinical characteristics of focal atrial tachycardia (FAT) and the efficacy of radiofrequency catheter ablation (RFCA) in pediatric FAT. Methods: A total of 125 children with FAT who were treated with RFCA in the First Hospital of Tsinghua University from January 2010 to July 2018 were involved in the study. The clinical characteristics, origin of FAT, success rate of RFCA and recurrence rate and complications post RFCA were retrospectively analyzed, and the efficacy and X-ray radiation were compared between two-dimensional (2D) and 3D mapping system by t test or Chi-square analysis. Results: Among the 125 children, 57 were males and 68 females, age of (7.6±3.5) years old and body weight of (27.7±13.3) kg; and 62 (49.6%) had paroxysmal FAT, and 63 (50.4%) incessant FAT. Twenty-seven patients (21.6%) presented with tachycardia-induced cardiomyopathy (TIC), and 22 of whom (81.5%) were secondary to the incessant FATs. Most of the FATs originated from atrial auricle (46/125, 36.8%). Ablation was successful in 111 children (88.8%), and the recurrence rate was 25.2% (28/111). No complications were identified in the whole group. The efficacy and safety of 3D mapping system (87 cases) was better than that of the 2D mapping system (38 cases), according to the lower recurrence rate ((19.0% (15/79) vs. 40.6% (13/32), χ2 = 3.849, P=0.049), shorter X-ray exposure time ((4.9±2.3) vs. (12.5±5.7) min, t=7.942, P<0.01) and lower radiation doses ((5.3±3.3) vs. (10.9±3.7) mGy, t=8.038, P<0.01). Conclusions: FAT in children is mainly originated from atrial auricle, and incessant FAT is prone to progress to tachycardia-induced cardiomyopathy. RFCA is safe and effective for drug-resistant or drug-intolerant FAT in children, and 3D mapping system should be preferred.

Abstract
A 66-year-old male presented with edema for 10 months and high fever for half a month. The patient was diagnosed with type 2 diabetes for 10 years. Renal biopsy revealed membrane nephropathy combined with diabetic nephropathy. A combination regimen with rituximab (1 g, day 1 and day 20), cyclophosphamide (100 mg/d) and prednisone (60 mg/d) was initiated. The dose of prednisone was gradually reduced to 17.5 mg/d within 1.5 months after partial remission of nephrotic syndrome. However, the patient was re-admitted due to high fever, productive cough and mild hand tremor. The lung imaging suggested the diagnosis of community-acquired pneumonia. Ertapenem (1 g/d) was empirically administrated and adjusted to moxifloxacin (0.4 g/d) plus ceftazidime (2 g, 2 times/d) for two weeks. The patient responded and temperature came back to normal. But the fever relapsed after the withdrawal of antibiotics. Mixed infections were suspected, but blood and sputum samples were negative for pathogens. Antibiotics were not effective. The patient recalled a history of pigeon exposure. Positive cryptococcus antigen in blood culture and cerebrospinal fluid unmasked the diagnosis of pulmonary cryptococcosis and cryptococcal meningitis. Fluconazole (200 mg, 2 times/d) and oral flucytosine (1 g, 3 times/d) were given and effective.

Abstract
Asparagus stem blight is a regional disease. In the present study, we compared strains of Phomopsis asparagi from six different provinces to determine their biological characteristics and genetic diversity, differences in the pycnidium and conidium production, pathogenicity, and growth rate. Considerable differences were established in the pycnidium and conidium production among the P. asparagi strains from the six studied provinces. The largest pycnidium and conidium production had the strains from Fujian, followed by those from Hainan. The virulence of P. asparagi strains was significantly different but without a correlation with the geographical source of the strain. FJ2 had the highest virulence, followed by HN2, SD4, and SD5, whereas SD5 had the lowest virulence. The colony diameter and dry weight of the strains of asparagus stem blight fungus from the six provinces were substantially different. The colonies of HN1-5 had the largest diameters, whereas those of XT1-5, LT1-3, FJ1-5, and SX6 had smaller diameters. Four primers with good repeatability and strong specificity were selected from 100 intersimple sequence repeat (ISSR) primers. ISSR-PCR amplification was performed on 36 strains of asparagus stem blight fungus, and a large number of repeatable DNA fingerprints were obtained. Most of the amplified fragments were within 300 to 500 bp. In all, 69 total points, 64 multiple points, and 92.75% polymorphism points were established. The number of ISSR gene sites detected by four primers ranged from 14 to 20, with an average of 16 multiple sites. The copolymerization was divided into three groups: XT1-5, LT1-3, and FJ1-5, which were clustered into the first group; SD1-6, SX1-6, and HB1-6, clustered into the second group; and HN1-5 in the third group. The results of the cluster analysis revealed that the strains of the neighboring provinces had a nearer phylogenetic relationship than that between distant ones. Therefore, the system evolution of P. asparagi is related to the geographical distribution of its strains.

Abstract
Objective: To investigate the efficacy and feasibility of transthoracic implantation of permanent left atrial and left ventricular dual-chamber pacemaker for synchronous treatment of cardiac dysfunction due to idiopathic complete left bundle branch block (CLBBB) in children. Methods: The clinical data of five children with cardiac dysfunction due to idiopathic CLBBB and accepting implantation of permanent left atrial and left ventricular epicardial dual chamber pacemaker from January 2015 to July 2019 at the Pediatric Cardiologic Department of the First Hospital of Tsinghua University were analyzed retrospectively. The effects of pacemaker implantation on patients' cardiac function and cardiac synchrony were evaluated by echocardiogram. Results: Among 5 patients, 2 were males and 3 females. At the time of pacemaker implantation, the age of these patients was 0.5-5.7 years, the left ventricle ejection fraction (LVEF) was 29%-46%, the left ventricle end stage of diastolic diameter was 30-53 mm and the mean Z score was 4.0-34.0. Pacemaker was successfully implanted for all the patients. After the implantation, medications that can suppress atrioventricular node conduction were used and sensed atrioventricular delay (SAV) parameters were modulated until patients' QRS duration became shortest and the percentage of left ventricular pacing increased to and maintained at 97% to 100%. Patients' QRS duration was 120-160 ms before implantation and 90-120 ms after implantation. Patients' cardiac function began to improve 1 day to 1 month after implantation. Patients' cardiac function normalized after a mean of 1-12 months. LVEF increased from 29%-46% to 55%-67%. During the follow-up, interventricular mechanical delay, septal-to-posterior wall motion delay, and left ventricular systolic dyssynchrony index decreased significantly: IVMD decreased from 31-62 ms to 26-50 ms; SPWMD decreased from 40-63 ms to 10-50 ms and Ts-SD decreased from 34.3-50.3 ms to 16.3-31.4 ms. The global longitudinal strain of left ventricle decreased from -7.7%--13.8% to -13.5%--20.3%. Conclusion: Cardiac dysfunction due to CLBBB in children can be treated with transthoracic implantation of permanent epicardial left atrial and left ventricular dual chamber pacemaker which can substitute three chamber pacemaker to achieve the effects of synchronous therapy that lead to reversion and normalization of cardiac function.

Abstract
Objective: To investigate the association between occupational stress and carotid atherosclerosis among the workers in a steel plant. Methods: In October 2018, a total of 2947 workers from a steel plant, who underwent occupational health examination in the center for occupational health examination from March to May 2017, were selected as subjects. Job Content Questionnaire (JCQ) and Effort-Reward Imbalance (ERI) were used to investigate the job content and the degree of occupational stress. According to the results of carotid artery examination, the subjects were divided into normal carotid artery group with 2013 workers, increased carotid intima-media thickness (IMT) group with 277 workers, stable plaque group with 236 workers, and unstable plaque group with 421 workers. A unified questionnaire was distributed to each group, and related physical and biochemical examinations were performed. A multivariate unconditional logistic regression analysis was performed to investigate the risk factors for unstable plaque. Results: There were significant differences between the groups in sex, educational level, marital status, work in shifts, smoking, drinking, age, and working years (P<0.05) , while there was no significant difference in exercise between groups (P>0.05) . Based on the JCQ score, 761 (25.8%) had no stress, 959 (32.5%) had mild stress, 699 (23.7%) had moderate stress, and 528 (17.9%) had severe stress; based on the ERI score, 2526 (85.7%) had high effort and low reward and 421 (14.3%) did not have the high-effort and low-reward conditions. There was a significant difference in the composition of JCQ and ERI scores between groups (P<0.05) . Moderate stress (odds ratio [OR]=1.695) , severe stress (OR=5.443) , ERI (OR=7.391) , work in shift (OR=1.784) , old age (OR=1.009) , high systolic blood pressure (OR=1.105) , high fasting blood glucose (OR=1.212) , abnormal total cholesterol (OR=3.693) , abnormal apolipoprotein B (OR=39.215) , and abnormal high-sensitivity C-reactive protein (OR=1.632) were the risk factors for unstable plaque. Conclusion: Occupational stress may be involved in the development of carotid atherosclerosis.

Abstract
On January 1st, 2019, one male patient, aged 55 years, with chronic ulcer in right lower extremity was admitted to Northern Jiangsu People's Hospital. After admission, ulcer debridement and vacuum sealing drainage (VSD) surgery was performed in lower right extremity. Two pieces of bone-like tissue was removed from the lateral space between the Achilles tendon and fibula in the right leg, which was confirmed as ossification tissue by histopathological sections after surgery. The wounds were treated with VSD technique and dressing changes. On the 49th day after surgery, split-thickness skin graft was taken from the lateral left thigh and grafted to the wound area, which was then treated with VSD. The skin graft of patient survived well. The wound healed completely and the patient was discharged from hospital on day 77 post hospitalization. This case suggests that the patients with chronic ulcer should complete all related examinations in time, and improving the blood circulation of the wound and clearing the ectopic ossification in the wound are critical for wound healing.

Abstract
Sjögren's syndrome is a chronic systemic autoimmune disease characterized by lymphocyte proliferation and progressive exocrine gland damage. In China, standardized diagnosis and treatment for Sjögren's syndrome lags behind other common rheumatic diseases, such as rheumatoid arthritis and systemic lupus erythematosus. Based on the evidence and guidelines from China and other countries, Chinese Sjögren's Syndrome Collaborative Research Group together with stomatologist and ophthalmologist developed Standardization of diagnosis and treatment of primary Sjögren's syndrome. The purposes are: (1) to standardize the detection and interpretation of key indicators for the diagnosis of Sjögren's syndrome, including serum anti SSA antibody and labial gland pathology; (2) to suggest using widely accepted disease activity index in evaluation of the disease; (3) to standardize rational management for Sjögren's syndrome patients with topical and systemic diseases.

Abstract
Objective: To explore changing trend in prognosis of primary hypopharyngeal carcinoma and to analyze the reasons at the Eye, Ear, Nose and Throat Hospital of Fudan University. Methods: We retrospectively analyzed the clinical data of 461 patients with primary hypopharyngeal carcinoma treated at the Eye, Ear, Nose and Throat Hospital of Fudan University from 2003 to 2007 (Group 1) and 2010 to 2014 (Group 2) according to the inclusion criteria. 142 from Group 1, including 133 males and 9 females, rangedfrom 38 to 82 years old and 319 from Group 2, including 313 males and 6 females, ranged from 39 to 81 years old, were included in this work. The laryngeal function preservation rate, survival outcome, application and effect of pre-and post-operative adjuvant therapy were compared. SPSS 24.0 was used for statistical analyses. Results: There were 62 patients with early disease (T1-2N0) including 18 in Group 1 and 44 in Group 2, in whom 3 (16.7%) underwent surgical procedures with laryngeal function preservation in Group 1, while, 30 (68.2%) underwent laryngeal function preservation surgery in Group 2. The laryngeal function preservation rate showed an obviously upward trend in recent years (χ(2)=13.617, P<0.001), whereas, the recurrence-free survival rate (RFS) and overall survival rate (OS) showed no significant differences between two groups (P=0.469 and 0.808, respectively). Among the 399 patients with advanced disease, 124 were in Group 1 and 275 in Group 2. After propensity score matching (PSM) was used, the OS rate was significantly higher for Group 2 than Group 1 (P=0.017), while the application of laryngeal function preservation surgery was significantly higher in Group 2 (χ(2)=4.686, P=0.030). The application rates of preoperative adjuvant therapy and postoperative adjuvant chemotherapy were significantly higher in group 2 than in group 1 (χ(2)=5.687, P=0.017; χ(2)=19.407, P<0.001). Conclusion: The application of laryngeal function preserving surgery significantly increases the retention rate of laryngeal functions in patients with early-stage hypopharyngeal carcinoma, with similar long-term survival outcomes. The application of comprehensive treatment including preoperative adjuvant therapy and postoperative adjuvant treatments, especially postoperative chemoradiotherapy, shows an obvious increase in the function preservation rate and long-term survival in patients with advanced hypopharyngeal carcinoma.

Abstract
Background Toxoplasma gondii (T. gondii) is an obligate intracellular parasite, which can affect the pregnancy outcomes in infected females by damaging the uterus, and the intrauterine environment as well as and the hypothalamus resulting in hormonal imbalance. However, the molecular mechanisms underlying the parasite-induced poor pregnancy outcomes and the key genes regulating these mechanisms remain unclear. Therefore, this study aimed to analyze the gene expression in the mouse’s uterus following experimentally-induced acute infection with T. gondii RH strain. Three groups of female mice were intraperitoneally injected with tachyzoites as follow; 3 days before pregnancy (FBD6), after pregnancy (FAD6), and after implantation (FID8) as the experimental groups. Another corresponding three groups served as control, were injected with normal saline at the same time. Transcriptome analysis of the total RNA extracted from both infected and non-infected mouse uterus samples was performed using RNA sequencing (RNA-Seq). Results The three experimental groups (FBD6, FAD6, and FID8) had a total of 4,561, 2,345, and 2,997 differentially expressed genes (DEGs) compared to the controls. The significantly upregulated and downregulated DEGs were 2,571 and 1,990 genes in FBD6, 1,042 and 1,303 genes in FAD6 and 1,162 and 1,835 genes in FID8 group, respectively. The analysis of GO annotation, and KEGG pathway showed that DEGs were mainly involved in anatomical structure development, transport, cell differentiation, embryo development, hormone biosynthetic process, signal transduction, immune system process, phagosome, pathways in cancer, and cytokine-cytokine receptor interaction pathways. Conclusion T. gondii infection can induce global transcriptomic changes in the uterus that may cause pregnancy hypertension, destruct the intrauterine environment, and hinder the normal development of placenta and embryo. Our results may help to understand the molecular mechanisms of the acute T. gondii infection, which could promote the development of new therapeutics or prophylactics for toxoplasmosis in pregnancy.

Abstract
Objective: To examine the mortality rate and relative factors associate with ventricular septal rupture in myocardial infarction patients. Methods: A total of 51 patients who suffered from myocardial infarction complicating with ventricular septal rupture received operative procedures between January 2005 and December 2018 in Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, were retrospectively analyzed. There were 34 males and 17 females, with an age of (63±8) years (range: 44 to 82 years). The time between ventricular septal rupture and surgical procedure was (44±39) days (range: 3 to 187 days). The t test and χ(2) test were used for univariate analysis, Logistics regression model was used for multivariate analysis of in-hospital mortality relative factors. Results: There were 8 patients dead in hospital, 43 patients survived, the overall mortality rate was 15.7% in hospital. The post-operation mortality rate was 2/3 of who suffered ventricular septal rupture and underwent operation within 1 week, but it's markedly decreased to 6.5% if the time over 4 weeks. Univariate analysis showed that renal failure before operation, creatinine before operation, left ventricular ejection fraction, cardiac function (New York Heart Association) grade Ⅳ, severe tricuspid regurgitation, dialysis post-operation, creatinine of the first day of post-operation, the time between and operation more than 4 weeks were in-hospital mortality relative factors. Multivariate analysis reflected that advanced age (OR=1.32, 95%CI: 1.05 to 1.75, P=0.033), cardiac function grade Ⅳ (OR=2.25, 95%CI: 1.62 to 2.82, P=0.003), severe tricuspid regurgitation (OR= 1.82, 95%CI: 1.31 to 2.43, P=0.001), renal failure before operation (OR=1.78, 95%CI: 1.26 to 2.32, P=0.015), the time between ventricular septal rupture and operation less than 1 week (OR=2.50, 95%CI: 1.52 to 2.98, P=0.012), were independent in-hospital mortality relative factors. Conclusions: The surgery operation is an effective way to deal with ventricular septal rupture combined with myocardial infarction. The independent relative factors of in-hospital mortality are advanced age, cardiac function grade Ⅳ, renal failure before operation, severe tricuspid regurgitation, the time between ventricular septal rupture and operation less than 1 week.

Abstract
Objective: To investigate the risk factors for diagnosis of transformation of high-grade dysplastic nodules (HGDN) to hypervascular hepatocellular carcinoma (HCC) in patients with chronic liver disease with gadoxetate disodium-enhanced magnetic resonance imaging (MRI). Methods: 2 037 cases that underwent gadoxetate disodium-enhanced magnetic resonance imaging from January 2012 to December 2014 were retrospectively analyzed. 51 cases of HGDN with a background of chronic liver disease were screened and followed-up for at least 2 times with gadoxetate disodium-enhanced MRI scans and contrast enhanced CT scans was performed within 1 month before and after the first MRI. The endpoint of study was transformation of HGDN to hypervascular hepatocellular carcinoma, with a deadline of April 2019. Transformation was divided into transformed (group A) and untransformed (group B) group according to the presence or absence of hypervascularization. Linear regression was used to analyze the possible risk factors for hypervascular transformation. Results: There were 36 nodules in group A and 79 nodules in group B, and hypervascular transformation rate was 31.3% (36/115). On univariate analysis, the length and diameter of nodule was > 10.2 mm (P = 0.034), with annual growth rate > 2% (P < 0.001), and lipid content (P = 0.007) was related to the occurrence of hypervascularity. On multivariate analysis, the annual growth rate of nodules was an independent risk factor for the occurrence of hypervascularity (P < 0.000 1). Conclusion: The annual growth rate of HGDN in patients with chronic liver disease diagnosed with gadoxetate disodium-enhanced MRI imaging can be used as a potential predictor of hypervascularization.

Abstract
The oncogene c-Myc is aberrantly expressed and plays a key role in malignant transformation and progression of hepatocellular carcinoma (HCC). Here, we report that c-Myc is significantly up-regulated by tumor necrosis factor receptor-associated factor 6 (TRAF6), an E3 ubiquitin ligase, in hepatocarcinogenesis. High TRAF6 expression in clinical HCC samples correlates with poor prognosis, and the loss of one copy of the Traf6 gene in Traf6+/- mice significantly impairs liver tumorigenesis. Mechanistically, TRAF6 first interacts with and ubiquitinates histone deacetylase 3 (HDAC3) with K63-linked ubiquitin chains, which leads to the dissociation of HDAC3 from the c-Myc promoter and subsequent acetylation of histone H3 at K9, thereby epigenetically enhancing the mRNA expression of c-Myc. Second, the K63-linked ubiquitination of HDAC3 impairs the HDAC3 interaction with c-Myc and promotes c-Myc protein acetylation, which thereby enhances c-Myc protein stability by inhibiting carboxyl terminus of heat shock cognate 70-kDa-interacting protein-mediated c-Myc ubiquitination and degradation. Importantly, TRAF6/HDAC3/c-Myc signaling is also primed in hepatitis B virus-transgenic mice, unveiling a critical role for a mechanism in inflammation-cancer transition. In clinical specimens, TRAF6 positively correlates with c-Myc at both the mRNA and protein levels, and high TRAF6 and c-Myc expression is associated with an unfavorable prognosis, suggesting that TRAF6 collaborates with c-Myc to promote human hepatocarcinogenesis. Consistently, curbing c-Myc expression by inhibition of TRAF6 activity with a TRAF6 inhibitor peptide or the silencing of c-Myc by small interfering RNA significantly suppressed tumor growth in mice. Conclusion: These findings demonstrate the oncogenic potential of TRAF6 during hepatocarcinogenesis by modulating TRAF6/HDAC3/c-Myc signaling, with potential implications for HCC therapy.

Abstract
A 43-year-old male presented with elevated serum creatinine for 4 years and developed abdominal pain for 3 days. He started peritoneal dialysis 2 months ago. Dialysis-related peritonitis was ruled out and acute gastroenteritis was diagnosed. The patient was administrated with ertapenem 500 mg/d. An acute mental abnormality developed 3 days later. After excluded organic encephalopathy, ertapenem was discontinued for the suspicion of antibiotic-related encephalopathy. The frequency of peritoneal dialysis was increased to accelerate the clearance of antibiotics. However, the metal abnormality became even more severe. Then a diagnosis of Wernick-Korsakoff syndrome was considered. After the administration of high dose vitamin B(1), the mental disorder dramatically relieved. Vitamin B(1) 30 mg/d is maintained during peritoneal dialysis and the mental disorder does not relapse.

Abstract
Objective: To investigate the clinical characteristics and prognostic factors after catheter ablation of accessory pathway (AP)-induced dilated cardiomyopathy (DCM) in children. Methods: Data were collected and analyzed on 147 consecutive pediatric patients (81males and 66 females), who hospitalized in our pediatric heart center between January 2009 and August 2018 and received catheter ablation for ventricular pre-excitation (right AP). Thirty-one children were diagnosed as AP-induced DCM and 116 children with normal cardiac function served as control. Data including clinical characteristics, electrocardiogram (ECG), echocardiography, electrophysiological examination (EPS), successful ablation and follow up were analyzed. Results: The median age at first examination was 3.07 (0.09, 5.83) years. The pre-hospital misdiagnosis rate was 87.1% (27/31). The incidence of the AP-induced DCM was 21.1% (31/147) and the rate of right anterior free wall accessory pathway (AP) was the highest (50.0%, 10/20). AP-induced DCM was more common in right free wall Aps (41.9%, 13/31) and right anterior free wall (32.3%, 10/31). 48.4% (15/31) cases had no supraventricular tachycardia (SVT). EPS showed that 29% (9/31) of the AP did not have retrograde conduction. The median follow-up time after successful catheter ablation was 8 (2, 36) months of AP-induced DCM group, LVDd was significantly decreased ((41.6±12.8)mm vs. (45.6±13.9)mm, P<0.01) and LVEF ((56.2±11.8)% vs. (40.8±12.5)%, P<0.01) was significantly increased after ablation. Cox regression analysis showed that LVEF was the predictor of the duration of cardiac function recovery (HR=1.08, 95%CI 1.01-1.15, P=0.03). Conclusions: Misdiagnosis rate is high for children with AP-induced DCM, leading to the delayed treatment. All of the AP-induced DCM occurred in right APs and right anterior free wall APs is the highest. Right free wall APs and right anterior free wall are most common in AP-induced DCM. Catheter ablation is a safe and effective treatment option for these patients. The lower the LVEF, the longer the cardiac function recovery.

Abstract
BACKGROUND Some researchers have reported that Toxoplasma gondii can cause serious reproductive impairment in male animals. Specifically, T. gondii destroy the quality of sperm in the epididymis, which affects their sexual ability. However, among such studies, none have investigated the male reproductive transcriptome. Therefore, to investigate the relationship between T. gondii and sperm maturation, we infected mice with T. gondii prugniaud (PRU) strain and performed transcriptome sequencing of the epididymis. RESULTS Compared with the control group, 431 upregulated and 229 downregulated differentially expressed genes (DEGs) were found (P-value < 0.05, false discovery rate (FDR) < 0.05 and |log2 (fold change)| ≥ 1). According to results of a bioinformatics analysis, Gene Ontology (GO) function is divided into three categories: cellular component, molecular function and biological process. Upon performing GO analysis, we found that some DEGs correlated with an integral part of membrane, protein complex, cell surface, ATP binding, immune system process, signal transduction and metabolic process which are responsible for the epididymal injury. DEGs were mapped to 101 unique KEGG pathways. Pathways such as cytokine-cytokine receptor interaction, glycolysis/gluconeogenesis and apoptosis are closely related to sperm quality. Moreover, Tnfsf10 and spata18 can damage the mitochondria in sperm, which decreases sperm motility and morphology. CONCLUSIONS We sequenced the reproductive system of male mice chronically infected with T. gondii, which provides a new direction for research into male sterility caused by Toxoplasma infection. This work provides valuable information and a comprehensive database for future studies of the interaction between T. gondii infection and the male reproductive system.

Abstract
Objective: To investigate the expression of nucleolar and spindle-associated protein 1 (NUSAP1) in non-small cell lung cancer (NSCLC) and analyze its relationship with the prognosis of NSCLC patients. Methods: Real-time fluorescent quantitative PCR and immunohistochemical staining were performed to determine the expression of NUSAP1 in NSCLC tissues and adjacent tissues collected from hospital. The relationship between NUSAP1 expression and prognosis of NSCLC patients was analyzed by online database. Results: The expression level of NUSAP1 mRNA in tumor tissues was significantly higher than that of adjacent tissues (P<0.05). The high expression rate of NUSAP1 protein in NSCLC tissues was 58.0% (29/50), significantly higher than 22.0% (11/50) of adjacent tissues (P<0.05). The high expression of NUSAP1 protein in NSCLC tissues was closely correlated with tumor size, lymph node metastasis and TNM stage (P<0.05), but was not related to age and gender. The data showed that the expression level of NUSAP1 mRNA was inversely associated with the overall survival (OS) of NSCLC patients (P<0.001). The expression of NUSAP1 mRNA was significantly correlated with the pathological grade, clinical stage, gender, chemotherapy, smoking history, and histological type of NSCLC patients (P<0.05). Conclusions: The expression of NUSAP1 is up-regulated in NSCLC, which is correlated with the growth and development of NSCLC and prognosis of the patients. These results indicate that NUSAP1 can be used as a potential prognostic marker for NSCLC.

Abstract
Objective: To investigate the clinical features and results of treatment for right atrial appendage aneurysms complicated by atrial tachyarrhythmias in children. Methods: This retrospective study included three children with right atrial appendage aneurysm complicated by atrial tachyarrhythmias (aged 1.0 to 5.3 years, weight 10 to 17.1 kg) who were hospitalized at the Pediatric Cardiology Department (Heart Center) of the First Hospital of Tsinghua University (Beijing Huaxin Hospital) during the period from January 2016 through April 2018. The patients' clinical features, the results of electrocardiogram (ECG) and echocardiography, the effects of therapeutic interventions (antiarrhythmics, radiofrequency ablation, and surgical resection of right atrial appendage aneurysm) and the results of pathological assessment were analyzed. Results: Three cases of right atrial appendage aneurysm were diagnosed at 36 weeks of gestational age, 1 month and 4 months after birth respectively. In two cases, ECG showed alternating episodes of atrial tachyarrhythmias including atrial tachycardia, atrial flutter, and atrial fibrillation, and echocardiography showed aneurysmal dilatation of right atrial appendage. These two cases underwent right atrial appendage aneurysm resection. In the remaining one case of atrial tachycardia, echocardiography did not visualize important lesions in the right atrium, thus the intracardiac electrophysiologic study and radiofrequency ablation were performed; and focal atrial tachycardia originating from the apex of right atrial appendage was mapped but failed to be ablated; consequently, the patient received the right atrial appendage resection, in which the right atrial appendage aneurysm was found. Preoperative multiple antiarrhythmics showed only modest or no efficacy for all the three cases. The atrial tachyarrhythmias disappeared in all the three cases after right atrial appendage aneurysm resection. Postoperative atrial tachycardias associated with new foci of impulse formation developed in two cases. These two patients reverted to normal sinus rhythm and remained in this rhythm by using antiarrhythmics. Pathological assessment showed cystic dilation of parts of atrial cavity, fibrosis of cyst wall, generalized fibrosis of atrial myocardium combined with myocardial atrophy and cystic dilation, as well as uneven myocardial thickness with generalized myocardial interstitial fibrosis. Conclusions: For patients with congenital right atrial appendage aneurysm, atrial tachyarrhythmias might develop during fetal stage or early postpartum period. Reliance on echocardiography might often lead to the missed diagnosis. These patients with atrial tachyarrhythmias responded poorly to antiarrhythmics. Radiofrequency ablation might be associated with a high risk and limited efficacy. Surgical resection of right atrial appendage aneurysm showed satisfactory results and should be highly recommended.

Abstract
Objective: To compare the 10 years risk for ischemic cardiovascular disease among Han, Uygur, Kazak nationality residents of Xinjiang Uygur Autonomous Region. Methods: From October 2007 to October 2010,14 618 adult (aged ≥35 years) Han (n=5 757),Uygur (n=4 767) and Kazak (n=4 094) residents were selected to join this study through the four-stage stratified cluster sampling method from 7 cities and regions of Xinjiang Uygur Autonomous Region. The 10 years risk for ischemic cardiovascular disease was calculated according to the 10 years ischemic cardiovascular disease risk assessment form modified with Chinese characteristics and compared among the residents of 3 nationalities. Results: (1) There were significant differences in age, body mass index, systolic blood pressure, diastolic blood pressure,fasting blood glucose,triglycerides,total cholesterol,low-density lipoprotein,high-density lipoprotein cholesterol, smoking history, and drinking history among Han, Uygur, Kazak nationality population (all P< 0.001). (2) There were significant differences in 10 years risk for ischemic cardiovascular disease between different gender and age group including 35-39, 40-44, 45-49, 50-54, 55-59, and ≥60 years old between Han, Uygur, Kazak nationality population (all P<0.001). (3) There were significant differences in rates of 10%-20% and>20% of 10 years risk for ischemic cardiovascular disease between different gender in Han, Uygur, Kazak nationality population (P values were 0.013 and <0.001, respectively). There were no significant differences in rates of <5% and 5%-9% of 10 years risk for ischemic cardiovascular disease between different gender in Han,Uygur,Kazak nationality population (all P>0.05).(4) There were significant differences in detection rates of diabetes,hypertension,smoking,hypertriglyceridemia,and obesity in male and female Han,Uygur,Kazak nationality population with 10 years risk for ischemic cardiovascular disease ≥10% (P<0.01 or 0.05). Meanwhile,there was significant difference in detection rates of hypercholesteremia in male Han, Uygur, Kazak nationality adults(P<0.001). There were no significant differences in detection rates of elevated low density lipoprotein cholesterol and reduced high density lipoprotein cholesterol in male and female Han,Uygur,Kazak nationality adults (all P>0.05). Conclusion: There are gender and age differences in the 10 years risk for ischemic cardiovascular disease in ≥35 years old Han,Uygur,Kazak nationality adults from Xinjiang Uygur Autonomous Region.

Abstract
Objective: To assess the clinical characteristics, pathogenic genes and therapeutic effects of congenital long QT syndrome (LQTS) in children. Methods: A retrospective analysis included 58 LQTS children (37 boys, 21 girls; age of diagnosis (8.0±4.1) years, range 0.1 to 16.0 years) at Division of Pediatric Cardiology, First Hospital of Tsinghua University from August 2013 to November 2017. Each patient was evaluated with a detailed medical history, 12-lead resting electrocardiogram, Doppler echocardiography, and molecular genetic analysis. Results: Forty-eight of the children (83%) had a delay to diagnosis (0.7 (0.1, 2.0)years) and initially received a misdiagnosis. QT prolongation of unknown origin was found in 10 cases (17%), complex arrhythmic conditions in 27 cases (47%), myocarditis in 3 cases (5%), syncope of unknown origin in 3 cases (5%), epilepsy in 2 cases (3%), myocardial infarction in 1 case (2%), cardiomyopathy in 1 case (2%), and vasovagal syncope in 1 case (2%). Nine children presented with the positive family history of LQTS and three children had congenital nervous deafness. Twenty-one (36%) children presented with recurrent syncope, and 14 cases of whom had symptoms during physical activity and/or emotional stress. The common arrhythmias were ventricular arrhythmia (26 cases), sinus node dysfunction (18 cases), atrioventricular block (AVB) (12 cases), and atrial arrhythmia (6 cases). LQTS-associated pathologic or possibly pathologic mutations were found in 41 children (71%). Thirty-three children (57%) were treated with propranolol (22 cases), permanent pacemaker (PM) combined with propranolol (5 cases), PM (4 cases), and implantable cardioverter defibrillator (ICD) combined with propranolol (2 cases). Eighteen children (55%) were asymptomatic, thirteen children (39%) reported infrequent syncope, and one case (2%) died. Conclusions: LQTS in children is potentially malignant and present as phenotypic diversity and complex arrhythmias. LQTS-related pathogenic or possibly pathogenic mutations are identified in most of the children. Beta-blockers therapy is effective in reducing the risk of malignant cardiac events. Some children with LQTS should receive PM or ICD therapy.

Abstract
Objective: To determine the relationship between nodal disease distribution patterns and oncological outcome and optimum management of cN0/cN1 patients with hypopharyngeal squamous cell carcinoma (HPSCC). Methods: The collected clinical data and the follow-up disease-free survival (DFS) information from 154 patients with HPSCC treated between 2001 and 2014 in Eye Ear Nose and Throat Hospital of Fudan University were retrospectively analyzed. Kaplan-Meier method was used to calculate DFS rate. Log-rank test and Cox regression model were performed to evaluate the survival prognostic factors for univariate and multivariate analyses. Results: Among 154 patients (63 cN0 patients, 91 cN1 patients) with HPSCC,in whom 148 were male, 6 were female, with an arerage age of (58.6±9.9), 63 cN0 patients received lateral neck dissection, of whom 9 were histologically positive nodes. Particularly, occult metastasis rate was 15.6%(7/45) for HPSCC in pyriform sinus and 18.2%(2/11) for HPSCC in posterior pharyngeal wall. Among 91 cN1 HPSCC, 34 underwent radical neck dissection and 54 underwent selective neck dissection. DFS for patients(T3-4N1) with radical neck dissection was lower than that for patient with selective neck dissection(15.2% vs.39.5%, χ(2)=5.153, P<0.05). The DFS of cN0 HPSCC was overestimated by the false-negative patients (cN0→pN+) for cN0 HPSCC and the DFS of cN1 HPSCC was underestimated by the false-positive(cN1→pN0) for cN1 HPSCC. Conclusions: For cN1 HPSCC, compared with radical neck dissection, selective neck dissection may be considered as a more adequate method for removal of metastatic lymph nodes. Postoperative combined therapy and follow-up strategy should be established according to pathological N staging.

Abstract
Objective: To explore the function and role of innate lymphoid cells in the pathogenesis of systemic lupus erythematosus (SLE) at different disease activity levels. Methods: From Nov 2017 to May 2018, 40 patients with SLE and 15 age-matched healthy non-immune-related diseases controls were enrolled from Anhui provincial hospital. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K, the patients were divided into active group (n=20) and remission group (n=20). The frequency of ILCs, B cells, CD4+T and CD8+T cells from peripheral blood mononuclear cells (PBMCs) was detected by flow cytometry. The subsets of ILCs in each group were compared with the subsets of B cells and T cell respectively. The levels of IL-4, IL-33 and IFN-γ in each group were tested by ELISA. Result: Compared with the control group, ILC1 percentage was significantly increased in SLE active group [(22.33%±2.52%) vs (14.56%±1.28%), P=0.018 1]; ILC2 percentage was decreased significantly in both remission group [(19.67%±1.83%) vs (42.48%±3.46%), P<0.000 1] and active group [(8.67%±0.83%) vs (19.67%±1.83%), P<0.000 1]; ILC3 percentage was decreased significantly in active group [(5.72%±1.08%) vs (14.35%±2.40%), P=0.001 3]. SLEDAI score was negatively correlated with the percentage of ILC2 (P=0.023 9) in all patients. The percentage of ILCs in the remission group (P=0.046 2) and activity group (P=0.003 7) were both increased significantly. Moreover, the percentage of ILC2 in active group was negatively correlated with CD4+T cells (P=0.030 8), and the serum IgG was negatively correlated with ILC2% in all patients (P=0.013 8). Compared with control group or remission group, the levels of IFN-γ (F=10.91, P=0.000 1) and IL-4 (F=6.046, P=0.004 7) in active group were remarkable higher. However, IL-33 was significantly reduced in active group (F=6.645, P=0.002 7). The percentage of ILC2 (r=0.154 3, P=0.028 8) and ILC3 (r=0.313 6, P=0.001 1) in all patients with SLE were positively correlated with the level of IL-4. Conclusion: The percentage of ILCs is related to disease activity, and ILCs play a "double-edged" role in the pathogenesis of SLE. Its function and mechanism are worth further exploration.

Abstract
Aberrant CTNNB1 signaling is one of the fundamental processes in cancers, especially colorectal cancer (CRC). Here, we reported that TRAF6, an E3 ubiquitin ligase important for inflammatory signaling, inhibited epithelial-mesenchymal transition (EMT) and CRC metastasis through driving a selective autophagic CTNNB1 degradation machinery. Mechanistically, TRAF6 interacted with MAP1LC3B/LC3B through its LC3-interacting region 'YxxL' and catalyzed K63-linked polyubiquitination of LC3B. The K63-linked ubiquitination of LC3B promoted the formation of the LC3B-ATG7 complex and was critical to the subsequent recognition of CTNNB1 by LC3B for the selective autophagic degradation. However, TRAF6 was phosphorylated at Thr266 by GSK3B in most clinical CRC, which triggered K48-linked polyubiquitination and degradation of TRAF6 and thereby attenuated its inhibitory activity towards the autophagy-dependent CTNNB1 signaling. Clinically, decreased expression of TRAF6 was associated with elevated GSK3B protein levels and activity and reduced overall survival in CRC patients. Pharmacological inhibition of GSK3B activity stabilized the TRAF6 protein, promoted CTNNB1 degradation, and effectively suppressed EMT and CRC metastasis. Thus, targeting TRAF6 and its pathway may be meaningful for treating advanced CRC.

Abstract
Idiopathic rapid eye movement sleep behavior disorder (iRBD) is often a precursor to neurodegenerative disease. However, voxel-based morphological studies evaluating structural abnormalities in the brains of iRBD patients are relatively rare. This study aimed to explore cerebral structural alterations using magnetic resonance imaging and to determine their association with clinical parameters in iRBD patients. Brain structural T1-weighted MRI scans were acquired from 19 polysomnogram-confirmed iRBD patients (male:female 16:3; mean age 66.6 ± 7.0 years) and 20 age-matched healthy controls (male:female 5:15; mean age 63.7 ± 5.9 years). Gray matter volume (GMV) data were analyzed based on Statistical Parametric Mapping 8, using a voxel-based morphometry method and two-sample t-test and multiple regression analysis. Compared with controls, iRBD patients had increased GMV in the middle temporal gyrus and cerebellar posterior lobe, but decreased GMV in the Rolandic operculum, postcentral gyrus, insular lobe, cingulate gyrus, precuneus, rectus gyrus, and superior frontal gyrus. iRBD duration was positively correlated with GMV in the precuneus, cuneus, superior parietal gyrus, postcentral gyrus, posterior cingulate gyrus, hippocampus, lingual gyrus, middle occipital gyrus, middle temporal gyrus, and cerebellum posterior lobe. Furthermore, phasic chin electromyographic activity was positively correlated with GMV in the hippocampus, precuneus, fusiform gyrus, precentral gyrus, superior frontal gyrus, cuneus, inferior parietal lobule, angular gyrus, superior parietal gyrus, paracentral lobule, and cerebellar posterior lobe. There were no significant negative correlations of brain GMV with disease duration or electromyographic activity in iRBD patients. These findings expand the spectrum of known gray matter modifications in iRBD patients and provide evidence of a correlation between brain dysfunction and clinical manifestations in such patients. The protocol was approved by the Ethics Committee of Huashan Hospital (approval No. KY2013-336) on January 6, 2014. This trial was registered in the ISRCTN registry (ISRCTN18238599).

Abstract
Objective:To explore the fundamental clinical characteristics and survival prognostic factors of laryngeal squamous cell carcinoma (LSCC) patients treated with open laryngeal function-preserving operations. Method: The collected clinical data and the follow-up survival information from 760 patients with LSCC undergoing open laryngeal function-preserving operations between January 2005 and December 2010 in Eye & ENT Hospital of Fudan University were retrospectively analyzed. Kaplan-Meier was applied to calculate survival rates. Log-rank test and Cox regression model were performed to evaluate the survival prognostic factors for univariate and multivariate analysis. Result: Among the enrolled 760 cases, 697 patients were glottic cancer, followed by 59 cases in supraglottis and 4 cases in subglottis. The number of laryngeal cancer patients staged in T1 to T4 was 222, 420, 112 and 6, respectively. 27 patients had positive cervical lymph nodes. There were 220, 408, 111 and 21 patients with clinical stage Ⅰ to Ⅳ, respectively. The 5-year overall survival (OS), disease free survival (DFS) and disease specific survival (DSS) rates were 89.3%, 83.9% and 89.8%, respectively. Multivariate Cox analysis indicated that clinical stage and second primary tumor were independent influencing factors for the OS rate, while, age, primary site, pathological differentiation, T stage, clinical stage and surgical margin were independent risk factors for tumor recurrence and progression (P<0.05). Conclusion: Open laryngeal function-preserving operation is a crucial therapeutic strategy applicable to LSCC patients in early and selected advanced stage in China. Early diagnosis and therapy, and sufficient safety surgical margin are keys for improving the survival rate and reducing the risk of relapse for laryngeal cancer patients.

Abstract
Recent studies indicate that circular RNA (circRNA) is involved in tumorigenesis, but its role in triple-negative breast cancer (TNBC) remains largely unknown. In this study, we characterized the role of circ-ITCH in TNBC and found that circ-ITCH was significantly down-regulated in TNBC tissues and cell lines and closely associated with poor prognosis. We therefore constructed the MDA-MB-231 and BT-549 TNBC cell lines stably expressing circ-ITCH by lentiviral vectors to determine its underlying mechanisms in TNBC progression. Most importantly, over-expression of circ-ITCH remarkably inhibited TNBC proliferation, invasion and metastasis both in vitro and in vivo. Mechanistically, we found that circ-ITCH acts as a sponge for miR-214 and miR-17 to increase expression of its ITCH linear isoform, thereby inactivating Wnt/β-catenin signaling. Our combined results show for the first time that circ-ITCH is a tumor suppressor, a promising prognostic biomarker in TNBC and that its restoration could well be a successful strategy in TNBC.

Abstract
Objective: To investigate the clinical features and evaluate the efficacy of radiofrequency catheter ablation (RFCA) guided by 3D electronic-anatomy mapping system (CARTO3 System) in children with atrioventricular nodal reentrant tachycardia (AVNRT). Methods: This was a retrospective case-controlled study. Data were collected from 95 children with AVNRT who underwent RFCA using CARTO3 System in the first hospital of Tsinghua University from January 2014 to December 2017. The onset age, characteristic of electrophysiology and anatomy feature of Koch triangle were analyzed. The efficacy and safety of ablation and X-ray fluoroscopy were compared with control 135 children with AVNRT who underwent RFCA without using CARTO3 System. The t test or the chi-square test was used for group comparison. Linear regression equation was established for correlation analysis. Results: The onset age of the 95 children (male 55, female 40; the average age (8.0±3.6) years) with AVNRT was (0.2-17.0) years and 23(24.2%) children were less than 3 years old. Electrophysiologic study showed that 84.2% (80 cases) was AVNRT-slow fast (SF), 11.6% (11 cases) AVNRT-slowslow and 4.2%(4 cases) AVNRT-fast slow. The phenomena of atrio-Hisian(AH) jump occurred in 65.3% and the interval of AH jump was (73.0±10.6) ms. The height of Koch triangle (CSo-His) was (22.3±5.8) mm and related with the weight of children (Y=0.171X+ 16.660, r(2)=0.224, P<0.001).The distance between the successful ablation target and the lowest point of His zone (ABL-His) was (11.7±2.6) mm. And there was no relation with the body weight(Y=-0.005X + 11.650, r(2)=0.001, P=0.780) and CSo-His (Y=0.072X+9.914, r(2)=0.030, P=0.171). The acute success rate was 97.9% (93/95) and recurrent rate was 5.4% (5/93) during follow-up. No obvious complication was reported. Compared with control group, the fluoroscopy time ((3.3±2.5) vs. (10.7±5.8) min, t=13.190, P<0.05), radiation dose ((5.4±4.9) vs. (15.5±6.3) mGy, t=13.660, P<0.05), and dose area product (514±445) vs. (2 478±415) mGy·cm(2), t=33.850, P<0.05) were decreased significantly. Conclusions: AVNRT-SF was the most common type of AVNRT. AVNRT incidence in infant and toddlers is lower than that in elder children. CSo-His is correlated with the body weight. ABL-His is relatively fixed. There is no correlation between ABL-His and the body weight and also no correlation between ABL-His and CSo-His. RFCA of AVNRT in children using the CARTO3 system is safe, effective and minimizes X-ray fluoroscopy.

Abstract
Background Ubiquitination is a basic post-translational modification for cellular homeostasis, and members of the conjugating enzyme (E2) family are the key components of the ubiquitin–proteasome system. However, the role of E2 family in colorectal cancer (CRC) is largely unknown. Our study aimed to investigate the role of Ube2v1, one of the ubiquitin-conjugating E2 enzyme variant proteins (Ube2v) but without the conserved cysteine residue required for the catalytic activity of E2s, in CRC. Methods Immunohistochemistry and real-time RT-PCR were used to study the expressions of Ube2v1 at protein and mRNA levels in CRC, respectively. Western blotting and immunofluorescence, transmission electron microscopy, and in vivo rescue experiments were used to study the functional effects of Ube2v1 on autophagy and EMT program. Quantitative mass spectrometry, immunoprecipitation, ubiquitination assay, western blotting, and real-time RT-PCR were used to analyze the effects of Ube2v1 on histone H4 lysine 16 acetylation, interaction with Sirt1, ubiquitination of Sirt1, and autophagy-related gene expression. Results Ube2v1 was elevated in CRC samples, and its increased expression was correlated with poorer survival of CRC patients. Ube2v1 promoted migration and invasion of CRC cells in vitro and tumor growth and metastasis of CRC cells in vivo. Interestingly, Ube2v1suppressed autophagy program and promoted epithelial mesenchymal transition (EMT) and metastasis of CRC cells in an autophagy-dependent pattern in vitro and in vivo. Moreover, both rapamycin and trehalose attenuated the enhanced Ube2v1-mediated lung metastasis by inducing the autophagy pathway in an orthotropic mouse xenograft model of lung metastasis. Mechanistically, Ube2v1 promoted Ubc13-mediated ubiquitination and degradation of Sirt1 and inhibited histone H4 lysine 16 acetylation, and finally epigenetically suppressed autophagy gene expression in CRC. Conclusions Our study functionally links Ube2v1, an E2 member in the ubiquitin–proteasome system, to autophagy program, thereby shedding light on developing Ube2v1 targeted therapy for CRC patients.
