Abstract
Objective: To evaluate the severe occlusal surface wear of implant-supported full-arch prostheses, and to explore the risk factors affecting the severe occlusal surface wear of implant-supported full-arch prostheses. Methods: Five hundred and thirty-five patients who received implant-supported fixed complete dental prostheses or implant-overdentures and completed at least one follow-up 3 months after the delivery of definitive prostheses were enrolled from October 1994 to October 2021 in this retrospective cohort study. The information on demographics, implants, definitive prostheses, and related outcomes was collected. Cox proportional hazard regression model was adopted to analyze the risk factors of the severe wear of occlusal surfaces in implant-supported full-arch prostheses. Univariate analysis was performed on the factors that may affect the severe wear of occlusal surfaces, and the parameters of P<0.10 in univariate analysis were included in multivariate analysis to explore the risk factors affecting the severe wear of occlusal surfaces in implant-supported full-arch prostheses. Results: Severe wear of the posterior occlusal surfaces was detected in 114 prostheses with a duration of 61.4 (33.3, 89.4) months. 13 cases occurred≤2 years after the delivery of definitive prostheses, 44 cases>2 years and≤5 years, 44 cases>5 years and≤10 years, and the other 13 cases>10 years. There was no significant difference in the average time of severe occlusal surface wear between implant-supported fixed complete dental prostheses and implant-overdentures in the maxilla (Z=-1.03, P=0.303). However, in the mandible, it was 48.2 (31.2, 80.2) and 79.2 (51.3, 119.1) months respectively, which was statistically significant (Z=-2.93, P=0.003). Cox proportional hazard regression model showed opposed fixed dentition, bruxism, and posterior resin occlusal surfaces were risk factors (P<0.05) affecting the severe wear of the occlusal surfaces. Conclusions: Severe occlusal surface wear was clinically common with the prolonged application of implant-supported full-arch prostheses. Prostheses opposed to fixed dentition, in patients with bruxism, and made of posterior resin materials were at higher risk of severe occlusal surface wear on the posterior artificial teeth. Regular follow-up, patients' behavior guidance, and clinicians' appropriate intervention were necessary to manage this complication.

Abstract
Objective: To investigate the effect of pretreatment with oral contraceptives (OC) on cumulative clinical pregnancy of oocyte retrieval cycle in polycystic ovary syndrome (PCOS) women with gonadotropin releasing hormone (GnRH) antagonist protocol. Methods: A retrospective cohort study was conducted to analyze PCOS women who underwent in vitro fertilization-embryo transfer (IVF-ET)/intracytoplasmic sperm injection (ICSI) treatment with GnRH antagonist in the Reproductive Medical Center of Peking University First Hospital from January 2017 to December 2020. A total of 225 patients were divided into OC pretreatment group (119 patients) and non-pretreatment group (106 patients), according to whether they received OC before GnRH antagonist protocol. The baseline information, IVF, and pregnancy outcomes of the two groups were compared. A multivariate logistic regression model was used to analyze the effect of OC pretreatment on cumulative clinical pregnancy of the oocyte retrieval cycle. Results: The age of 225 patients was (31.1±3.3) years old. The ages of patients in the OC pretreatment group and non-pretreatment group were (31.0±3.3) and (31.2±3.3) years old (P>0.05), respectively. The cumulative clinical pregnancy rate of oocyte retrieval cycle was significantly higher in the OC pretreatment group than that in the non-pretreatment group (79.8%, 95 patients; 67.0%, 71 patients; P=0.029). Age <35 years old (OR=3.199, 95%CI: 1.200-8.531, P=0.020), OC pretreatment (OR=3.129, 95%CI: 1.305-7.506, P=0.011), number of oocytes retrieved (OR=1.102, 95%CI: 1.007-1.206, P=0.035) and number of high-quality embryos (OR=1.536, 95%CI: 1.205-1.957, P=0.001) were related factors for the cumulative clinical pregnancy of oocyte retrieval cycle. Conclusions: OC pretreatment before GnRH antagonist protocol can significantly increase the cumulative clinical pregnancy rate of oocyte retrieval cycle in women with PCOS. Age <35 years old, OC pretreatment, the number of oocytes retrieved, and the number of high-quality embryos were related factors for the cumulative clinical pregnancy of oocyte retrieval cycle.

Abstract
Objective: To investigate the effects of calorie-restricted diet (CRD), high protein diet (HPD), high protein, and high dietary fiber diet (HPD+HDF) on metabolic parameters and androgen level in overweight/obese patients with polycystic ovary syndrome(PCOS). Methods: Ninety overweight/obese patients with PCOS from Peking University First Hospital from October 2018 to February 2020 were given medical nutrition weight loss therapy for 8 weeks and were randomly divided into CRD group, HPD group, and HPD+HDF group, with 30 patients in each group. Body composition, insulin resistance, and androgen level were detected before and after weight loss, and the efficacy of three weight loss therapies was compared through variance analysis and Kruskal-Wallis H test. Results: Eight patients in CRD group quit because they could not strictly complete the follow-up, therefore at the end of weight loss, 22, 30, and 30 patients in CRD group, HPD group and HPD+HDF group, respectively, were included in the final analysis. The baseline ages of the three groups were (31±2) years, (32±5) years and (31±5) years, respectively (P=0.952). After weight loss, the relevant indicators in HPD group and HPD+HDF group decreased more than those in CRD group. The body weight of CRD group, HPD group and HPD+HDF group decreased by 4.20 (11.92, 1.80), 5.00 (5.10, 3.32) and 6.10 (8.10, 3.07) kg, respectively (P=0.038); BMI of the three groups decreased by 0.80 (1.70, 0.40), 0.90 (1.23, 0.50) and 2.20 (3.30, 1.12) kg/m2, respectively (P=0.002); homeostatic model assessment-insulin resistance(HOMA-IR) index decreased by 0.48(1.93, 0.05), 1.21(2.91, 0.18) and 1.22(1.75, 0.89), respectively (P=0.196); and free androgen index(FAI) decreased by 0.23(0.67, -0.04), 0.41(0.64, 0.30) and 0.44(0.63, 0.24), respectively (P=0.357). Conclusions: The three medical nutrition therapies can effectively reduce the weight of overweight/obese patients with PCOS, and improve insulin resistance and hyperandrogenism. Compared with CRD group, HPD group, and HPD+HDF group have better fat-reducing effect, and can better preserve muscle and basal metabolic rate while losing weight.

Abstract
BACKGROUND Programmed cell death protein-1 (PD-1) blockade therapies have demonstrated efficacy in nasopharyngeal carcinoma (NPC). Thyroid dysfunction is among the most common immune-related adverse events. This study aimed to explore the clinical pattern of thyroid dysfunction and its relationship with survival marker in nonmetastatic NPC after immunotherapy. METHODS From January 1, 2019, to December 31, 2021, 165 pairs of nonmetastatic NPC patients (165 with and 165 without anti-PD-1 immunotherapy) matched by the propensity score matching method were included in this study. Thyroid function was assessed retrospectively before the first treatment and during each immunotherapy cycle. RESULTS The spectrum of thyroid dysfunction was different between the immunotherapy and control groups (P < 0.001). Compared with the control group, patients in the immunotherapy group developed more hypothyroidism (14.545% vs. 7.273%), less hyperthyroidism (10.909% vs. 23.636%), and a distinct pattern, biphasic thyroid dysfunction (3.030% vs. 0%). Immunotherapy also accelerates the onset of hypothyroidism, which was earlier with a median onset time difference of 32 days (P < 0.001). Patients who acquired thyroid dysfunction during immunotherapy had better complete biological response to treatment (OR, 10.980; P = 0.042). CONCLUSIONS For nonmetastatic NPC, thyroid dysfunction was associated with better response to treatment in immunotherapy but not in routine treatment. Thyroid function could be used as a predictor for survival and should be under regular and intensive surveillance in clinical practice of anti-PD-1 immunotherapy for nonmetastatic NPC.

Abstract
Objective: To analyze the genotypes and clinical phenotypes of patients with epilepsy associated with IQSEC2 gene variants. Methods: The genotypes, seizure types, electroencephalogram, neuroimage of 6 patients with IQSEC2 gene variants in the Department of Pediatrics, Peking University First Hospital from July 2019 to October 2021 were analyzed. Results: There were 5 males and 1 female. Six variants were de novo, including 2 frameshift variants (c.3801_3808dup/p.Q1270Rfs*130, c.1459_1460delAT/p.M487Vfs*2), 2 nonsense variants (c.3163C>T/p.R1055*, c.1417G>T/p.E473*), 1 in-frame deletion (c.2295_2297del/p.N765del) and 1 missense variant (c.2293A>G/p.N765D). Age at seizure onset ranged from 3 months to 2 years and 5 months. Multiple seizure types were observed, including epileptic spasms in 5 patients, focal seizures in 5 patients, tonic seizures in 3 patients, myoclonic seizures in 3 patients, atypical absence seizures in 2 patients and atonic seizures in 2 patients. All 6 patients showed global developmental delay before seizure onset. There were other clinical manifestations, including autistic features in 3 patients, microcephaly in 3 patients, dystonia in 2 patients and binocular esotropia in 1 patient. The electroencephalogram showed slow background activity and hypsarrhythmia in all 6 patients. Brain magnetic resonance imaging showed abnormal in 5 patients and normal in 1 patient. Five patients were diagnosed with infantile spasms. Among them, 4 patients had late-onset infantile spasms. One patient was unclassified developmental epileptic encephalopathy. The age of last follow-up ranged from 3 years and 2 months to 7 years and 2 months. All 6 patients still had seizures after multiple anti-seizure medications. Conclusions: The seizure onset of patients with IQSEC2 gene variants usually begins after 1 year of age. The common seizure types include epileptic spasms and focal seizures. Patients usually have a global developmental delay before seizure onset. IQSEC2 variants could be related to developmental and epileptic encephalopathy, and most patients are diagnosed with late onset infantile spasms. Epilepsy associated with IQSEC2 gene variants is usually refractory.

Abstract
PURPOSE The aims of this study focusing on Locoregionally advanced nasopharyngeal carcinoma (LANPC) were mainly two-fold: on the one hand, to establish a cut-off value to differentiate early and late failure based on prognosis after recurrence or metastasis; and on the other hand, to investigate the duration of concurrent cisplatin benefit over follow-up time. The results of our study have the potential to guide clinical practice and follow-up. METHODS In total, 3123 patients with stage III-IVa NPC receiving Induction chemotherapy followed by concurrent cisplatin or not were analysed. The cut-off value of treatment failure was calculated using the minimum P-value approach. Random survival forest (RSF) model was to simulate the cumulative probabilities of treatment failure (locoregional recurrence and /or distant metastasis) over-time, as well as the monthly time-specific, event-occurring probabilities, for patients at different treatment groups. RESULTS Based on subsequent prognosis, early locoregional failure (ELRF) should be defined as recurrence within 14 months (P = 1.47 × 10 - 3), and early distant failure (EDF) should be defined as recurrence within 20 months (P = 1.95 × 10 - 4). A cumulative cisplatin dose (CCD) > 200 mg/m2 independently reduced the risk of EDF (hazard ratio, 0.351; 95% confidence interval (CI), 0.169-0.732; P = 0.005). Better failure-free survival (FFS) and overall survival (OS) were observed in concurrent chemotherapy settings ([0 mg/m2 vs. 1-200 mg/m2 vs. >200 mg/m2]: FFS: 70.4% vs. 74.4% vs. 82.6%, all P < 0.03; OS: 79.5% vs. 83.8% vs. 90.8%, all P < 0.01). In the monthly analysis, treatment failure mainly occurred during the first 4 years, and the risk of distant failure in patients treated with concurrent chemotherapy never exceeded that of patients without concurrent chemotherapy. CONCLUSION Locoregional failure that developed within 14 months and/or distant failure within 20 months had poorer subsequent survival. Concurrent chemotherapy provides a significant FFS benefit, primarily by reducing EDF, translating into a long-term OS benefit.

Abstract
The patient was found to develop a migrating mass in the lower abdomen without any known cause in 2000, and the cause had not been identified following multiple diagnoses since then. The mass was found to migrate to the left anterior axillary regions on August 11, 2020. Then, three segments of incomplete white worms were resected through minimally invasive surgery, and metagenomic sequencing revealed sparganosis mansoni. After surgical resection of complete worms was performed on October 21, 2021, the case was cured and discharged from the hospital. Follow-up revealed satisfactory outcomes and no new mass was found throughout the body.

Abstract
Objective: To summarize the genetics and clinical phenotypes of epilepsy children with 2q24.3 microdeletion. Methods: All the patients with 2q24.3 microdeletion were retrospectively collected at the Pediatric Department of Peking University First Hospital from March 2017 to July 2022. The features of clinical manifestations, electroencephalogram (EEG), and neuroimaging were analyzed. Results: There were 13 patients with 2q24.3 microdeletion were included. All 13 patients had de novo copy number variation (CNV) with a deletion size ranged 0.18-7.31 Mb. The main pathogenic genes in the region were SCN3A, SCN2A, TTC21B, SCN1A and SCN9A genes. Among the 13 patients, 7 were boys, and 6 were girls. The onset age of epilepsy was 3.3(2.5, 6.0) months. Multiple seizure types were observed, including focal seizures in 13 patients, generalized tonic-clonic seizures (GTCS) in 6 patients, myoclonic seizures in 3 patients, epileptic spasm in 2 patients, and tonic seizures in 2 patients. Seizures were fever sensitivity in 9 patients. Status epilepticus was observed in 6 patients. One case had normal mental motor development and 12 cases had different degrees of developmental delay. Six patients had craniofacial abnormality, 1 had six-finger deformity of the right thumb, and 1 had multiple system abnormalities. EEG showed focal discharge in 3 cases, multifocal discharges in 5 cases, multifocal and generalized discharges in 1 case. Brain magnetic resonance imaging (MRI) showed enlargement of subarachnoid spaces in the frontal and temporal region in 4 patients, enlargement of lateral ventricle in 4 patients and delayed myelination of white matter in 1 patient. Dravet syndrome was diagnosed in 5 cases. The age at the last follow-up were 2.5(1.4,5.5) years, 1 patient was seizure free longer than 1 year, and 12 patients still had seizures. Conclusions: The epilepsy associated with 2q24.3 microdeletion is mainly induced by the deletion of SCN3A, SCN2A and SCN1A genes. The seizure onset age of 2q24.3 microdeletion related epilepsy was in infancy. Multiple seizure types are observed and the common seizure types include focal seizures and GTCS. Most patients have fever sensitivity and status epilepticus. Most patients have developmental delay. The phenotype of patients with deletion of SCN3A and SCN2A gene is more severe than that of patients with deletion of SCN1A gene only.

Abstract
Oxygen plays an important role in the process of wound healing. Researches have shown that more than 97% of chronic wounds are in a state of hypoxia, which is one of the key factors resulting in refractory wounds. Local oxygen therapy is a treatment method that can directly provide oxygen to wounds without relying on the damaged vascular system. It can effectively promote chronic wounds healing by transmitting sufficient oxygen to wounds through specific devices or preparations. Hemoglobin spray is a new form of local oxygen therapy, which has the advantages of good effect, simple operation, and low cost. This article reviews the development, component, safety, oxygen supply principle, and application methods of hemoglobin spray and its effects in the treatment of chronic wounds, so as to provide a new direction for the treatment of chronic wounds.

Abstract
OBJECTIVES To explore the efficacy of induction chemotherapy (IC) plus concurrent chemoradiotherapy (CCRT) in stage II nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT). METHODS Totally, 450 eligible patients with staged II NPC on the basis of the 8th edition of the AJCC/UICC TNM staging system were eventually included from January 2010 to September 2020. The one-to-one propensity score-matched (1:1 PSM) analysis was employed to balance variables. We conducted univariate and multivariate analysis of survival to identify prognostic factors and demonstrated the findings in the matching cohort. RESULTS In total, 141 pairs were selected by 1:1 PSM. IC + CCRT group in the matched data decreased 5-year progression-free survival (PFS, 75.5% vs. 88.0%, p = 0.032) and distant metastasis-free survival (DMFS, 86.0% vs. 96.5%, p = 0.009). There was no significant difference in 5-year overall survival (OS, 93.8% vs. 95.6%, p = 0.192) and locoregional relapse-free survival (LRRFS, 87.1% vs. 94.3%, p = 0.169) compared with RT/CCRT. Multivariate analysis indicated that IC + CCRT was associated with significantly poor PFS (p = 0.024) and DMFS (p = 0.010). High neutrophil-to-lymphocyte ratio (>4.1) was negatively associated with OS (p = 0.034), PFS (p = 0.017) and DMFS (p = 0.001). CONCLUSION Adding IC to CCRT or IMRT alone has decreased PFS and DMFS, therefore, IC should not be recommended in stage II NPC patients. No significant differences in OS and LRRFS were observed in stage II disease.

Abstract
Environmental endocrine disruptors (EDCs) are ubiquitous in the environment, and detectable amounts are found in humans worldwide. EDCs can interact with nuclear receptors such as estrogen receptor, which could interfere with the normal function of endocrine system, and further cause the pathological alterations in the tissues. This article summarizes several common types of EDCs in the environment, which caused cardiac function abnormalities, and morphological growth malformations in heart as well as its relevant mechanisms, including oxidative stress, inflammatory response, changes in signal transduction, expressions of transcriptional regulatory factors, which are related to cardiac development, receptor pathways and cell apoptosis etc., for the purpose of understanding the process of EDCs-induced cardiac developmental toxicity, and further providing scientific theoretical basis for figuring out the toxicity mechanism of EDCs and the prevention and treatment of cardiac diseases.

Abstract
Objective: To explore the clinical features and treatment strategy of rare tumor in the internal auditory canal(IAC). Methods: A retrospective study was carried out in 213 patients with lesion of ICA form January 2010 to December 2020. According to imaging features, surgical findings, and pathological diagnosis, there were 7 cases of non-sporadic acoustic neuroma, including 2 cases of cavernous hemangioma, 2 cases of aneurysm, 1 case of intralabyrinthical schwannoma, 1 case of meningioma, and 1 case of unilateral neurofibromatosis type 2 (NF2). The clinical manifestations, imaging data and intraoperative conditions as well as the formulation of individualized treatment strategies and prognosis were comprehensively analyzed. Results: In addition to hearing loss, cavernous hemangioma early appeared damage of facial nerve. CT showed expansion and calcification of IAC. Patients with aneurysm appeared tinnitus and vertigo early. CT showed enlargement of ampulla shape of IAC. DSA or MRA can help confirm the diagnosis. Patients with intralabyrinthine schwannoma early appeared refractory vertigo. High resolution MRI was helpful for diagnosis. "Dural tail sign" can be seen on enhanced MRI of meningeoma. Neurofibromatosis type 2 usually presented as bilateral vestibular schwannomas,but a few patients presented only with unilateral vestibular schwannomas.. All patients underwent labyrinth approach resection except one patient with NF2 for followed-up. Their postoperative symptoms were relieved. No tumor recurrence was observed during 6-3 years of follow-up. Conclusions: The clinical and imaging manifestations of rare tumors of the internal auditory canal are different. The principle of treatment is also different. It is helpful to avoid the serious consequences caused by blind operation to confirm diagnosis before operation.

Abstract
Adaptation to reduced energy production during aging is a fundamental issue for maintaining healthspan or prolonging life span. Currently, however, the underlying mechanism in long-lived people remains poorly understood. Here, we analyzed transcriptomes of 185 long-lived individuals (LLIs) and 86 spouses of their children from two independent Chinese longevity cohorts and found that the ribosome pathway was significantly down-regulated in LLIs. We found that the down-regulation is likely controlled by ETS1 (ETS proto-oncogene 1), a transcription factor down-regulated in LLIs and positively coexpressed with most ribosomal protein genes (RPGs). Functional assays showed that ETS1 can bind to RPG promoters, while ETS1 knockdown reduces RPG expression and alleviates cellular senescence in human dermal fibroblast (HDF) and embryonic lung fibroblast (IMR-90) cells. As protein synthesis/turnover in ribosomes is an energy-intensive cellular process, the decline in ribosomal biogenesis governed by ETS1 in certain female LLIs may serve as an alternative mechanism to achieve energy-saving and healthy aging.

Abstract
Objective: To summarize the phenotypes of epilepsy in patients with MBD5 gene variants. Methods: A total of 9 epileptic patients, who were treated in the Department of Pediatrics, Peking University First Hospital from July 2016 to September 2021 and detected with MBD5 gene pathogenic variants, were enrolled. The features of clinical manifestations, electroencephalogram (EEG), and neuroimaging were analyzed retrospectively. Results: Among 9 patients, 6 were male and 3 were female. Age at seizure onset ranged from 5 to 89 months. Multiple seizure types were observed, including generalized tonic clonic seizures (GTCS) in 7 patients, myoclonic seizures in 5 patients, focal seizures in 5 patients, atypical absence seizures in 3 patients, atonic seizures in 2 patients, myoclonus absence seizures in 1 patient, epileptic spasms in 1 patient, and tonic seizures in 1 patient. There were 8 patients with multiple seizure types, 2 patients with sensitivity to fever and 5 patients with clustering of seizures. Two patients had a history of status epilepticus. All patients had developmental delay before seizure onset. Nine patients had obvious language delay, and 6 patients had autism-like manifestations. Five patients had slow background activity in EEG. Interictal EEG showed abnormal discharges in 9 patients. Brain magnetic resonance imaging (MRI) was normal in all patients. A total of 9 epileptic patients carried MBD5 gene variants, all of them were de novo variants. There were MBD5 gene overall heterozygous deletion in 1 patient, large fragment deletions including MBD5 gene in 3 patients and single nucleotide variations (c.300C>A/p.C100X, c.1775delA/p.N592Tfs*29, c.1759C>T/p.Q587X, c.150_151del/p.Lys51Asnfs*6, c.113+1G>C) in 5 patients. The age at last follow-up ranged from 2 years and 9 months to 11 years and 11 months. At the last follow-up, 2 patients were seizure-free for more than 11 months to 4 years 6 months, 7 patients still had seizures. Conclusions: The initial seizure onset in patients with MBD5 gene variants usually occurs in infancy. Most patients have multiple seizure types. The seizures may be fever sensitive and clustered. Developmental delays, language impairments, and autistic behaviors are common. MBD5 gene variants include single nucleotide variations and fragment deletions. Epilepsy associated with MBD5 gene variants is usually refractory.

Abstract
Objective: To investigate the clinical features and the value of different diagnostic indices for etiology in reproductive age women with hyperandrogenism. Methods: The medical records of 96 reproductive age women with hyperandrogenism in the multi-disciplinary team of Peking University First Hospital from January 2020 to April 2021 were collected. The patients were divided into four groups based on final diagnosis: congenital adrenal hyperplasia (CAH) (n=8), polycystic ovary syndrome (PCOS) (n=67), idiopathic hyperandrogenism (n=13) and other specific diseases (n=8), respectively. The indices related to androgens in different groups were compared, and then their efficiency for diagnosis of CAH and PCOS were analyzed with receiver operator characteristic curve (ROC curve). Results: A total of 96 patients with hyperandrogenism were recruited, with the age of 19-45 (29±6) years old. Overall, 4.2% (4/96) of the patients were with single clinical hyperandrogenism, 56.3% (54/96) were with single laboratory hyperandrogenaemia and 39.6% (38/96) were with both. The breakdown into laboratory hyperandrogenaemia subtypes was as follows: only T elevation 22.8% (21/92), only A2 elevation 7.6% (7/92), none DHEAS elevation, only FAI elevation 5.4% (5/92) and elevation of more than one of the androgen indices mentioned above accounted for 64.1% (59/92). In the reasons of consultation, simple irregular menstruation (36.0%, 32/89) or accompanied by clinical hyperandrogenism with or without infertility (36.0%, 32/89) were the most common. As for primary visiting departments, Obstetrics and Gynecology accounted for 53.2% (51/96), and then Endocrinology as 39.5% (38/96). The 17-OHP level of CAH, PCOS and idiopathic hyperandrogenism group was 20.0 (8.2, 33.1), 1.1 (0.8, 1.4), 0.9 (0.8, 1.3) ng/ml, respectively. The androstenedione level in these groups was 6.3 (4.6, 8.7), 3.8 (2.9, 4.8) and 3.2 (2.7, 3.7) ng/ml, respectively. The 17-OHP and androstenedione levels of CAH group were significantly higher than that in PCOS or idiopathic hyperandrogenism group (all P<0.05). The ratio of LH and FSH in these three groups was 0.8(0.5, 1.0), 1.3(0.6, 1.9) and 0.6(0.3, 0.7), respectively. The ratio of LH and FSH was significantly higher in PCOS than that in idiopathic hyperandrogenism group (P=0.024), but yet there was no significant difference compared with CAH group (P>0.05). The AUC of ROC curve of 17-OHP for CAH diagnosis was 0.94, followed by androstenedione 0.83, whereas LH/FSH for PCOS diagnosis was only 0.63. Conclusions: Among the reasons of consultation in reproductive age women who visited our multi-disciplinary team for female hyperandrogenism, simple irregular menstruation or accompanied by clinical hyperandrogenism with or without infertility are the most common. PCOS accounts for the majority of different androgen excess disorders. 17-OHP is the most valuable parameter for the diagnosis of CAH and secondly androstenedione.

Abstract
Objective: To explore the risk factors and preventive strategies of pancreatitis after percutaneous transhepatic biliary drainage (PTBD) in patients with pancreatic cancer and obstructive jaundice. Methods: A total of 241 patients were retrospectively analyzed from May 2001 to October 2014 in Tianjin Medical University Cancer Institute and Hospital. The possibly correlated 9 factors were analyzed, including gender, age, hemoglobin level, total bilirubin level, degree of pancreatic duct dilatation, degree of pancreatic atrophy, degree of biliary stenosis, the pancreatic duct visualization, and drainage mode. Results: Univariate analysis suggested that pancreatic duct dilatation, pancreatic atrophy, visualized pancreatic duct and drainage mode were associated with the incidence of pancreatitis after PTBD (P<0.05). Logistic regression analysis showed that visualization of pancreatic duct (OR=6.33) was a risk factor for pancreatitis, while pancreatic duct dilatation (OR=0.14), pancreatic atrophy (OR=0.12) and external drainage (OR=0.11) were protective factors for pancreatitis. Conclusion: In pateints with pancreatic cancer and obstructive jaundice, pancreatic duct dilatation and pancreatic atrophy predict low risk of pancreatitis after PTBD,while intraoperative pancreatic duct visualization and internal or external drainage may increase the incidence of postoperative pancreatitis.

Abstract
Objective: To investigate the clinical indicators for preoperative prediction of impacted ureteral stones and analyze the predictive value of ureteral wall area(UWA). Methods: A total of 197 patients who underwent ureteroscopic lithotripsy due to ureteral stones at our institution from January to December 2020 were retrospectively analyzed. Preoperative patient age, gender, body mass index (BMI), history of hypertension, diabetes mellitus, side of stone, location of stone, maximum diameter of stone, CT value of stone, C-reactive protein (CRP), creatinine, renal pelvis diameter, ureteral wall thickness and UWA were collected. Patients were divided into impacted and non-impacted groups according to whether the stones were impacted intraoperatively. Univariate analysis was used to compare the differences in each clinical indicator between the two groups, and multivariate logistic regression was performed to analyze the independent predictors of impacted stones for those with differences. The receiver operating characteristic (ROC) curve was used to analyze the predictive power of each independent predictor, and the Delong test was used to analyze whether the difference in the area under the curve (AUC) of each independent predictor was statistically significant. Results: All 197 patients successfully completed the operation, aged 51 (36, 56) years; 137 males and 60 females. According to the results of ureteroscopy, they were divided into 82 cases of impacted ureteral stones and 115 cases of non-impacted ureteral stones. Univariate analysis showed that there were significant differences in maximum stone diameter, stone CT value, renal pelvis diameter, ureteral wall thickness and ureteral wall area between the two groups (P<0.05); There was no significant difference in age, gender, BMI, history of hypertension, diabetes, stone side, location of stone, CRP and creatinine (P>0.05). Multivariate logistic regression analysis showed that stone CT value (P<0.01), ureteral wall thickness (P<0.001) and ureteral wall area were independent predictors of impacted ureteral stones (P<0.001). The ROC curve was used to compare the predictive efficacy of independent predictors of stone CT value, ureteral wall thickness and ureteral wall area. The area under the ureteral wall area curve was the largest (AUC = 0.901, 95%CI: 0.859-0.943, P<0.001), followed by ureteral wall thickness (AUC = 0.799, 95%CI: 0.736-0.862, P<0.001) and stone CT value (AUC = 0.700, 95%CI: 0.626-0.775, P<0.001). By Delong test, there were significant differences in AUC between ureteral wall area and stone CT value (Z=4.527, P<0.001) and ureteral wall thickness (Z=3.407, P<0.001). The best predictive value of ureteral wall area was 79.6 mm2. The sensitivity and specificity of this critical value for predicting ureteral incarcerated calculi were 80.1% and 89.5%. Conclusions: The UWA, ureteral wall thickness as well as the CT value of stones were all independent predictors of impacted ureteral stones, and UWA had a better predictive value.

Abstract
(1) Purpose: This study aims to explore risk-adapted treatment for elderly patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) according to their pretreatment risk stratification and the degree of comorbidity. (2) Methods: A total of 583 elderly LA-NPC patients diagnosed from January 2011 to January 2018 are retrospectively studied. A nomogram for disease-free survival (DFS) is constructed based on multivariate Cox regression analysis. The performance of the model is evaluated by using the area under the curve (AUC) of the receiver operating characteristic curve and Harrell concordance index (C-index). Then, the entire cohort is divided into different risk groups according to the nomogram cutoff value determined by X-tile analysis. The degree of comorbidities is assessed by the Charlson Comorbidity Index (CCI). Finally, survival rates are estimated and compared by the Kaplan–Meier method and the log-rank test. (3) Results: A nomogram for DFS is constructed with T/N classification, Epstein-Barr virus DNA and albumin. The nomogram shows well prognostic performance and significantly outperformed the tumor-node-metastasis staging system for estimating DFS (AUC, 0.710 vs. 0.607; C-index, 0.668 vs. 0.585; both p < 0.001). The high-risk group generated by nomogram has significantly poorer survival compared with the low-risk group (3-year DFS, 76.7% vs. 44.6%, p < 0.001). For high-risk patients with fewer comorbidities (CCI = 2), chemotherapy combined with radiotherapy is associated with significantly better survival (p < 0.05) than radiotherapy alone. (4) Conclusion: A prognostic nomogram for DFS is constructed with generating two risk groups. Combining risk stratification and the degree of comorbidities can guide risk-adapted treatment for elderly LA-NPC patients.

Abstract
Objective: To summarize the genotypes and clinical features of neonatal-onset genetic epilepsy. Methods: Patients (114 cases) with identified gene variants were collected from May 2013 to May 2019 in Peking University First Hospital, retrospectively. The genotype, clinical, electroencephalographic and neuroimaging characteristics were analyzed. Results: A total of 141 neonatal-onset epilepsy patients with identified gene variants were enrolled, including 76 males and 65 females and involving 33 epilepsy genes. Top five genes were KCNQ2 (56 cases), SCN2A (25 cases), STXBP1 (9 cases), CDKL5 (8 cases) and KCNT1 (6 cases), accounting for 73.8% (104/141). The age of seizure onset was 3(1-28) days of age, 71.6% (101/141) were within 1 week of age. The age of genetic diagnosis was 4 months (1 month to 13 years) of age. A total of 130 patients presented focal seizures; 47 patients presented epileptic spasms. Other seizure types included generalized tonic-clonic seizures, clonic seizures, myoclonic seizures, tonic seizures and absence seizures. Fifty-eight patients experienced multiple seizure types. The results of video-electroencephlogram (VEEG) were abnormal in 127 patients and in 62 patients clinical seizures were captured. Global developmental delay was presented in 122 patients. Epilepsy syndromes were diagnosed in 59 patients. Thirteen patients were diagnosed as Ohtahara syndrome (OS), 9 as epilepsy of infancy with migrating focal seizures (EIMFS), 17 as West syndrome (WS), 4 as OS developed to WS, 9 as benign neonatal epilepsy (BNE), 2 as benign familiar neonatal-infantile epilepsy (BFNIE), 2 as benign infantile epilepsy (BIE) and 3 as benign familial infantile epilepsy (BFIE). Sixty-seven patients were diagnosed as unclassified early infantile epileptic encephalopathy (EIEE), 13 patients could not be diagnosed as any epilepsy syndrome, and 2 patients were diagnosed as pyridoxine-dependent epilepsy. Forty-six patients had abnormal neuroimaging including cortical atrophy, corpus callosum dysplasia and cerebellar atrophy, involving 19 genes. Conclusions: Neonatal-onset epilepsy is related to many different genes. Seizure onset age of most patients is within one week after birth. Focal seizures and epileptic spasms are more common. Some patients show abnormal neuroimaging.

Abstract
The mechanism of osteoarthritis is still not completely clear,the current treatment can not effectively prevent the disease from progressing.In order to study osteoarthritis,researchers have developed various models,including in vitro models (two-dimension and three-dimension cell culture models and bioreactor culture models) and in vivo models (spontaneous,genetically modified,invasive and non-invasive models).These models are important tools for studying the mechanism of disease occurrence and development,which can simulate the whole process or a certain stage of pathological changes,as well as evaluating the effect of treatment.This paper reviews the osteoarthritis models and their characteristics in order to provide reference for osteoarthritis research.

Abstract
BACKGROUND The optimal posttreatment surveillance strategy for nasopharyngeal carcinoma (NPC) remains unclear. Circulating cell-free Epstein-Barr virus (cfEBV) DNA has been recognized as a promising biomarker to facilitate early detection of NPC recurrence. Therefore, we aim to determine whether integrating circulating cfEBV DNA into NPC follow-up is cost-effective. METHODS For each stage of asymptomatic nonmetastatic NPC patients after complete remission to primary NPC treatment, we developed a Markov model to compare the cost-effectiveness of the following surveillance strategies: routine follow-up strategy, i.e., (1) routine clinical physical examination; routine imaging strategies, including (2) routine magnetic resonance imaging plus computed tomography plus bone scintigraphy (MRI + CT + BS); and (3) routine 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT); cfEBV DNA-guided imaging strategies, including (4) cfEBV DNA-guided MRI + CT + BS and (5) cfEBV DNA-guided PET/CT. Clinical probabilities, utilities, and costs were derived from published studies or databases. Sensitivity analyses were performed. RESULTS For all disease stages, cfEBV DNA-guided imaging strategies demonstrated similar survival benefits but were considerably more economical than routine imaging strategies. They only required approximately one quarter of the number of imaging studies compared with routine imaging strategies to detect one recurrence. Specifically, cfEBV DNA-guided MRI + CT + BS was most cost-effective for stage II (incremental cost-effectiveness ratio [ICER] $57,308/quality-adjusted life-year [QALY]) and stage III ($46,860/QALY) patients, while cfEBV DNA-guided PET/CT was most cost-effective for stage IV patients ($62,269/QALY). However, routine follow-up was adequate for stage I patients due to their low recurrence risk. CONCLUSIONS The cfEBV DNA-guided imaging strategies are effective and cost-effective follow-up methods in NPC. These liquid biopsy-based strategies offer evidence-based, stage-specific surveillance modalities for clinicians and reduce disease burden for patients.

Abstract
Objective: To evaluate the clinical effect of oral contraceptive (OC) pretreatment on the outcome of gonadotropin releasing hormone antagonist (GnRH-a) protocol in patients with non-polycystic ovary syndrome. Methods: From January 2017 to May 2019, a total of 436 patients undergoing in vitro fertilization and embryo transfer/Intracytoplasmic sperm injection (IVF-ET/ICSI) treatment in Peking University First Hospital reproductive center clinic were included in this retrospective cohort study. A total of 144 patients (147 cycles) used OC pretreatment prior to GnRH-a protocol and 292 patients (306 cycles) used GnRH-a protocol without OC pretreatment. The drug usage as well as pregnant outcomes between groups were examined. The primary outcome was the cumulative clinical pregnancy rate of oocyte retrieval cycle and the secondary outcome included the number of oocytes, MⅡ oocytes, embryos and clinical pregnancy rate of fresh embryo transfer cycle. Results: The median ages (and Q1, Q3) of OC pretreatment group and non-OC group were 33 (30,36) and 34 (30,38) years old, respectively. The number of MⅡ oocytes was higher in OC pretreatment group (7/9) than in non-OC group (6/8) (P=0.002). The significant difference were not found in the cumulative clinical pregnancy rate of each oocyte retrieval cycle (61.7% vs 54.6%), the clinical pregnancy rate of fresh embryo transfer cycle (34.4% vs 35.6%), and the number of oocytes (9 vs 8) and embryos (6 vs 6) between groups. Conclusion: Our findings suggest that compared to non-OC pretreatment group, pretreatment with OC is associated with more MⅡ oocytes, and with an increasing trend of the cumulative clinical pregnancy rate in non-polycystic ovary syndrome patients undergoing fresh IVF-ET/ICSI.

Abstract
Objective: To explore the diagnostic value of serum amyloid A (SAA) and C-reactive protein (CRP) for predicting acute aortic dissection (AAD). Methods: One hundred and seventy-five AAD patients and 160 patients with acute coronary syndrome (disease control group) who were admitted to Cardio-cerebrovascular Disease Hospital of General Hospital of Ningxia Medical University from January 2018 to June 2020 were retrospectively selected. Meanwhile, 148 healthy subjects (healthy control group) who underwent physical examination were also enrolled. The latex-enhanced immunoturbidimetric assay and the latex immunoturbidimetric assay were used to determine the serum SAA and CRP levels of all subjects, and related clinical data were collected and analyzed. Univariate and multivariate logistic regression analyses were performed to analyze the independent risk factors, and the receiver operating characteristic (ROC) curve was drawn to calculate the diagnostic value of SAA and CRP for predicting AAD. Results: The levels of SAA and CRP in the AAD patient group ((165.7±7.4) mg/L and (76.0±4.0)mg/L) were significantly higher than those of the healthy control group ((6.5±0.4) mg/L and (3.9±0.2) mg/L) and the disease control group ((27.2±1.3) mg/L and (9.4±3.2) mg/L), with significant differences (all P<0.05). Compared with patients less than 60 years, levels of SAA and CRP in AAD patients over 60 years old decreased ((150.6±12.7) mg/L and (73.9±7.3) mg/L), and there were significant differences (both P<0.05). Likewise, SAA levels in AAD patients with high-risk pain characteristics over 6 h increased compared to those with pain less than 6 h, and there was a significant difference (P<0.05). SAA was positively correlated with CRP (r=0.053 4, P<0.05). ROC analysis showed that SAA and CRP levels were independently related to the risk of AAD (P=0.001), and the ROC curve of SAA for predicting AAD showed that the area under the curve (AUC) of type A aortic dissection (TAAD) and type B aortic dissection (TBAD) were 0.997 and 0.995, respectively (both P<0.001). And the ROC curve of CRP for predicting AAD demonstrated that the AUC of TAAD and TBAD were 0.998 and 0.991, respectively (both P<0.001). The best cut-off values of SAA and CRP for predicting AAD were 175.17 mg/L and 72.96 mg/L, respectively. Conclusion: Increased levels of SAA and CRP have high predictive value for AAD, and SAA combined with CRP is expected to serve as a laboratory marker to assist the diagnosis of AAD.

Abstract
PURPOSE To develop predictive models with dosimetric and clinical variables for temporal lobe injury (TLI) in nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS Data of 8194 NPC patients who received IMRT-based treatment were retrospectively reviewed. TLI was diagnosed by magnetic resonance imaging. Dosimetric factors were selected by penalized regression and machine learning, with area under the receiver operating curve (AUC) calculated. Cox proportional hazards models containing the most predictive dosimetric factor with/without clinical variables were performed. A nomogram was generated as a visualization of Cox regression for predicting TLI-free survival. RESULTS During median follow-up of 66.8 months (interquartile range [IQR] 54.2-82.2 months), 12.1% of patients (989/8194) developed TLI. Median latency from IMRT to TLI was 36 months (IQR 28-47 months). D0.5cc (dose delivered to 0.5-cm3 temporal-lobe volume) was the most predictive dosimetric factor (AUC: 0.799). Tolerance dose for 5% and 50% probabilities to develop TLI in 5 years were 65.06 Gy (95% confidence interval [CI]: 64.19-65.92) and 89.75 Gy (95% CI: 87.39-92.11), respectively. A nomogram comprising age, T stage, and D0.5cc significantly outperformed the model with only D0.5cc in predicting TLI (C-index: 0.78 vs. 0.737 in train set; 0.775 vs. 0.73 in test set; both P < 0.001). The nomogram-defined high-risk group had worse 5-year TLI-free survival. CONCLUSIONS D0.5cc of 65.06 Gy was the tolerance dose of the temporal lobe. Reducing D0.5cc decreased risk of TLI, especially in older patients with advanced T stage. The nomogram could predict TLI precisely and allow individualized follow-up management.

Abstract
Enhancement of light extraction efficiency (LEE) of AlGaN-based deep-ultraviolet (DUV) light emitting diodes (LEDs) has been attempted by adopting Ag-nanodots/Al reflective electrodes on a highly transparent complex p-type layer. By thinning the p-GaN to several nm, highly DUV transparent p-type layer is achieved, making it meaningful for the application of reflective electrodes composed of Ag-nanodots and Al film to allow most light emitted upward to be reflected back to the sapphire side. By this approach, the maximum light output power and external quantum efficiency of the DUV-LEDs with optimized Ag nanodots/Al electrodes are severally increased by 52% and 58%, respectively, compared to those with traditional Ni/Au electrodes when the current is below 200 mA.

Abstract
PURPOSE To evaluate how prevertebral space involvement (PSI) and degree of tumor extension within the space affects prognosis in nasopharyngeal carcinoma (NPC). PARTICIPANTS AND METHODS Data of patients with newly-diagnosed nonmetastatic NPC (n = 757) were retrospectively analyzed. Patients were separated into groups according to presence or absence of PSI and degree of tumor spread. Overall survival (OS), failure-free survival (FFS), local relapse-free survival (LRFS), and distant metastasis-free survival (DMFS) were compared between the groups. RESULTS Prevalence of PSI, simple prevertebral muscle involvement (PMI), and behind prevertebral muscle involvement (BPMI) were 44.9% (340/757), 22.5% (170/757), and 22.5% (170/757), respectively. OS, FFS, LRFS, and DMFS for patients with and without PSI were 64% vs. 84.8%, 68% vs. 85.6%, 85.8% vs. 94.4%, and 78.5% vs. 92.8%, respectively (all P < 0.001). PSI was an independent predictor of OS, FFS, LRFS, and DMFS. OS, FFS, and DMFS for patients with simple PMI and with BPMI were 72.7% vs. 54.8% (P = 0.002), 75.8% vs. 59.8% (P = 0.003), and 85.5% vs. 71.2% (P = 0.002), respectively. Degree of PSI extension was related to OS, FFS, and DMFS. OS, FFS, LRFS, and DMFS were significantly poorer in patients with PSI in T2-3 stage than in patients without PSI in T3 stage (P < 0.05), but comparable to those in patients with T4 stage (P > 0.05). CONCLUSIONS PSI predicts poor prognosis in NPC. Survival is poorer in patients with BPMI than in those with simple PMI. NPC with PSI should be classified as T4 stage.

Abstract
Background Conditional survival (CS) provides dynamic prognostic estimates by considering the patients existing survival time. Since CS for endemic nasopharyngeal carcinoma (NPC) is lacking, we aimed to assess the CS of endemic NPC and establish a web‐based calculator to predict individualized, conditional site‐specific recurrence risk. Methods Using an NPC‐specific database with a big‐data intelligence platform, 10,058 endemic patients with non‐metastatic stage I–IVA NPC receiving intensity‐modulated radiotherapy with or without chemotherapy between April 2009 and December 2015 were investigated. Crude CS estimates of conditional overall survival (COS), conditional disease‐free survival (CDFS), conditional locoregional relapse‐free survival (CLRRFS), conditional distant metastasis‐free survival (CDMFS), and conditional NPC‐specific survival (CNPC‐SS) were calculated. Covariate‐adjusted CS estimates were generated using inverse probability weighting. A prediction model was established using competing risk models and was externally validated with an independent, non‐metastatic stage I–IVA NPC cohort undergoing intensity‐modulated radiotherapy with or without chemotherapy (n = 601) at another institution. Results The median follow‐up of the primary cohort was 67.2 months. The 5‐year COS, CDFS, CLRRFS, CDMFS, and CNPC‐SS increased from 86.2%, 78.1%, 89.8%, 87.3%, and 87.6% at diagnosis to 87.3%, 87.7%, 94.4%, 96.0%, and 90.1%, respectively, for an existing survival time of 3 years since diagnosis. Differences in CS estimates between prognostic factor subgroups of each endpoint were noticeable at diagnosis but diminished with time, whereas an ever‐increasing disparity in CS between different age subgroups was observed over time. Notably, the prognoses of patients that were poor at diagnosis improved greatly as patients survived longer. For individualized CS predictions, we developed a web‐based model to estimate the conditional risk of local (C‐index, 0.656), regional (0.667), bone (0.742), lung (0.681), and liver (0.711) recurrence, which significantly outperformed the current staging system (P < 0.001). The performance of this web‐based model was further validated using an external validation cohort (median follow‐up, 61.3 months), with C‐indices of 0.672, 0.736, 0.754, 0.663, and 0.721, respectively. Conclusions We characterized the CS of endemic NPC in the largest cohort to date. Moreover, we established a web‐based calculator to predict the CS of site‐specific recurrence, which may help to tailor individualized, risk‐based, time‐adapted follow‐up strategies.

Abstract
PURPOSE To assess the impact of tumor necrosis on treatment sensitivity and long-term survival in patients with nasopharyngeal carcinoma (NPC) treated using intensity-modulated radiation therapy (IMRT). PARTICIPANTS AND METHODS In total, 757 patients with non-metastatic, histologically confirmed NPC were retrospectively examined. All patients were treated using IMRT; 93.7% patients with stage T3-T4/N1-N3 disease also received cisplatin-based chemotherapy. RESULTS The incidence rates of tumor necrosis in primary tumor, retropharyngeal lymph nodes, neck lymph nodes, and total tumor were 2%, 17.7%, 21.5%, and 31.4%. Overall, 40.8% patients with necrosis of the total tumor achieved complete response (CR) and 54.7% patients without tumor necrosis achieved CR at the end of treatment (χ2 = 12.728, P < 0.001). The estimated 7-year overall survival (OS), failure-free survival (FFS), distant metastasis-free survival (DMFS), and loco-regional relapse-free survival (LRRFS) for patients with tumor necrosis and without tumor necrosis of the total tumor were 68.5% vs. 88.4%, 70.5% vs. 88.1%, 77.6% vs. 90.6%, and 85.9% vs. 91.3%, respectively (all P < 0.001). Multivariate analyses indicated that necrosis of the total tumor was an independent predictor of OS, FFS, DMFS, and LRRFS. The impact of lymph node necrosis on long-term survival was similar to that of necrosis of the total tumor. ROC curves verified that inclusion of lymph node necrosis improved the predictive value of the current N classification criteria (P = 0.006). CONCLUSIONS Tumor necrosis served as a predictor of treatment sensitivity and poor prognosis for patients with NPC. Lymph node necrosis significantly improved the prognostic value of the current N classification criteria for NPC.

Abstract
Objective: To research the mitochondrial cytochrome c oxidase subunit I (MT-COI) gene methylation levels in patients with occupational chronic benzene poisoning, and to explore effective molec μlar biomarkers in patients with occupational chronic benzene poisoning. Methods: 38 confirmed cases of occupational chronic benzene poisoning were selected in the case group. 46 healthy people who underwent physical in our hospital were selected in the control group. Pyrosequencing was used to detect the methylation sites of methylation sites, flow cytometry was used to detect peripheral blood cell count levels, and non-parametric statistical methods were used to analyze the differences in detection results between the two groups. Results: The methylation level of mitochondrial MT-COI site 1 (2.21±0.81) % in the case group was less than that in the control group, and the difference was statistically significant (P<0.05) . The methylation level of mitochondrial MT-COI site 2 (2.31±0.96%) in the case group was less than that in the control group, and the difference was statistically significant (P<0.05) . The methylation average level of mitochondrial MT-COI (2.26±0.75) % in the case group was less than that in the control group, and the difference was statistically significant (P<0.05) . Analysis of the average level of methylation found that the methylation level of mitochondrial MT-COI was correlated with WBC (P<0.05) . Analysis of the average level of methylation found that the methylation level of mitochondrial MT-COI was correlated with platelets (r=0.254、0.280, P<0.05) . Conclusion: The level of mitochondrial MT-COI gene methylation in patients with occupational chronic benzene poisoning may be related to the sensitivity to benzene exposure. Mitochondrial MT-COI gene methylation may serve as a potential predictive biomarker for benzene poisoning.

Abstract
We aimed to investigate the prognostic value of radiation interruptions at different times on the overall survival (OS) and disease‐free survival (DFS) of patients with nasopharyngeal carcinoma receiving intensity‐modulated radiation therapy. Totally, 4510 patients were identified from a well‐established big‐data intelligence platform. Optimal interruption thresholds were identified using Recursive partitioning analyses. Actuarial rates were plotted using the Kaplan–Meier method and were compared using the log‐rank test. Patients with preceding interruptions ≥1 d (5‐year OS, 89.6% vs. 85.7%, p < 0.001; 5‐year DFS, 81.4% vs. 76.4%, p < 0.001), or latter interruptions ≥4 d (88.4% vs. 82.3%, p < 0.001; 79.2% vs. 75.1%, p = 0.006) showed significant detrimental effects on OS and DFS than patients without those interruptions. However, no significant lower survival was identified in latter interruptions ≥1 d (5‐year OS: 89.0% vs. 86.7%, p = 0.053; 5‐year DFS, 80.2% vs. 77.8%, p = 0.080). Latter interruptions ≥4 d was an independent unfavorable prognostic factor for OS (HR, 1.404; 95% CI, 1.143–1.723, p = 0.001) and DFS (HR, 1.351; 95% CI, 1.105–1.652, p = 0.003) in multivariate analysis. Radiation interruptions longer than 3 days that occurred in the latter period of treatment with IMRT were independent factors in poorer survival. Efforts are needed to minimize radiation interruptions and improve the timely provision of treatment.

Abstract
Objective: To investigate the epidemiological characteristics of a family clustering of COVID-19. Methods: Field epidemiological survey was conducted. Results: Case 1 of the long-term residents from Hubei province was the source of infection of this family clustering. There were 6 cases (from case 2 to case 7) infected in the whole incubation period. The incubation period was more than 14 days for 3 of the second-generation cases. Routes of transmission included respiratory droplets (from case 1 transmitted to case 6, from case 1 to her family members) and close contact (from case 1 to other cases in her family). All the age groups were generally susceptible, while elderly were easier to progress to critically ill. Besides respiratory symptoms, there were also gastrointestinal symptoms, of which diarrhea was the most common one. Conclusions: Family clustering had been an important part for COVID-19 cases.

Abstract
Objective: To explore the effects and mechanisms of Dendrobium nobile Lindl. alkaloids (DNLA) on myocardial lipid metabolism during ischemia-reperfusion in dogs undergoing cardiopulmonary bypass (CPB). Methods: Twenty-four healthy hybrid dogs, half male and half female, were randomly divided into sham group, model group, solvent control group and treatment group (DNLA, 6 mg/kg) (n=6), all of which were established with CPB. Except for the sham group, the aorta of the other groups was occluded for 60 min and then reopened. The uptake rate of free fatty acids, the concentration of long-chain acyl coenzyme A (LCACoA), mRNA and protein expression of fatty acid translocase enzyme/CD36 (FAT/CD36) in myocardial tissue and the cardiac function indexes were measured at 4 time points: before cardiopulmonary bypass (T1), 15 min (T2), 60 min (T3), and 90 min (T4) after reperfusion in each group. Results: Before CPB, there were no statistically significant differences in the uptake rate of free fatty acids, the concentration of LCACoA and mRNA expression of FAT/CD36 in myocardial tissue in each group (P>0.05). After the opening of the aorta, the above indexes in model group [(35.8±4.7)%, (8.55±1.51) nmol/g, 3.23±0.68] and treatment group [(27.4±2.7)%, (6.10±1.38) nmol/g, 2.20±0.56] were higher than those in sham group [(19.6±3.9)%, (4.16±0.81)nmol/g, 1.19±0.52], which were the highest at T2, and then gradually decreased (all P<0.05). Compared with the model group, the increase of above indicators in the treatment group was significantly lower at T2 (all P<0.05). Before CPB, there was no statistically significant differences in cardiac function indexes [left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP) and±dp/dtmax] among the groups (P>0.05). After the aorta was opened, the above indexes in model group [(76.5±9.1) mmHg, (31.1±2.9) mmHg, (1.2±0.4) mmHg/ms, (-0.9±0.1) mmHg/ms] and treatment group [(92.9±8.7) mmHg, (25.3±3.6) mmHg, (1.8±0.4) mmHg/ms, (-1.3±0.1) mmHg/ms] were lower than those in sham group [(165.5±12.9) mmHg, (6.5±0.5) mmHg, (3.3±0.6) mmHg/ms, (-2.9±0.3) mmHg/ms] (all P<0.05), but the impairment degree of cardiac function indicators in treatment group was significantly lower than that those in model group (all P<0.05). Conclusion: During CPB in dogs, DNLA can inhibit the abnormal expression of FAT/CD36, decrease the uptake of free fatty acids, and reduce the abnormal accumulation of LCACoA in myocardium,thereby alleviating the myocardial injury after ischemia-reperfusion.

Abstract
Objective: To summarize the clinical phenotypes of epilepsy in patients with GABRA1 gene variants. Methods: A total of 11 epileptic patients (4 boys and 7 girls) who were treated in the Department of Pediatrics, Peking University First Hospital from March 2016 to July 2019 and detected with GABRA1 gene heterozygous pathogenic variants by targeted next-generation sequencing were enrolled. The features of clinical manifestations, electroencephalogram (EEG), and neuroimaging were analyzed retrospectively. Results: A total of 11 epileptic patients carried GABRA1 gene pathogenic variants, of whom 10 were de novo variants and the other one was inherited from the patient's mother. Two patients had the same variants. Six variants were novel. Ages at seizure onset ranged from 3 to 14 months, and the median age was 8 months. The seizure was first observed within 1 year in 10 patients and beyond 1 year of age in 1 patient. Multiple seizure types were observed, including focal seizures in 10 patients, generalized tonic clonic seizures (GTCS) in 3 patients, myoclonic seizures in 3 patients, and epileptic spasm in 2 patients. There were 5 patients with multiple seizure types. Sensitivity to fever was observed in 9 patients, among whom 6 patients had a history of status epilepticus. Two patients had photoparoxysmal response. Five patients had abnormal EEG background, and 6 patients had abnormal discharges in EEG during interictal phase. Brain magnetic resonance imaging (MRI) was normal in all patients. Developmental delay in various degrees was present in 9 patients. Among the 11 patients, Dravet syndrome was diagnosed in 5 patients, West syndrome in 2 patients, undiagnosed early-onset epileptic encephalopathy in 1 patient, and focal epilepsy in the other 3 patients. The ages at the last follow-up ranged from 8 months to 12 years. During follow-up, 8 patients were seizure-free for 6 months to 8 years, and 1 patient had discontinuation of medication. Conclusions: In epilepsy associated with GABRA1 gene variants, de novo pathogenic variants are more common than inherited. Most epilepsy caused by GABRA1 gene variants occurs in infancy. Most patients have multiple seizures and focal seizures are common. Most patients have a comparatively favorable prognosis, but they may still have varied degrees of developmental delay.

Abstract
Objective: To evaluate the application of combinatorial probe anchor synthesis (cPAS)-based high-throughput low coverage whole genome sequencing in chromosomal aberration detection in spontaneous miscarriage. Methods: From September 2015 to May 2017, spontaneous miscarriage samples were collected from Inner Mongolia Maternal and Child Health Care Hospital. Those samples were further analyzed with two independent methods, fluorescence in situ hybridization (FISH) and low coverage whole genome sequencing on the BGISEQ-500 high-throughput platform. The performance of low coverage whole genome sequencing was assessed by comparing to FISH results. Results: In 595 spontaneous miscarried specimens, low coverage whole genome sequencing revealed 144 cases (24.2%, 144/595) chromosomal abnormalities, of which a subset of 137 cases (23.0%, 137/595) were detected as aneuploidies, 2 cases (0.3%, 2/595) as mosaicisms and 5 cases (0.8%, 5/595) as copy number variation (≥5 Mb). Conclusion: cPAS-based high-throughput low coverage whole genome sequencing is a reliable method in detecting chromosomal aberrations inspontaneous abortion tissues, including chromosome aneuploidies, mosaicisms and copy number variation (≥5 Mb).

Abstract
Objective: To explore the effect of tracheotomy combined with thyrocricocentesis and puncture of front tracheal wall in emergency treatment of laryngeal edema in patients with burns. Methods: From November 2000 to August 2018, 22 patients with severe burn or extremely severe burn combined with acute laryngeal edema were rescued in the author's unit, including 18 males and 4 females, aged 17 to 68 years. All patients were complicated with mild inhalation injury or above and more than deep partial-thickness burn to head, face, and neck. From November 2000 to October 2012, simple emergency tracheotomy was performed for 12 cases. From May 2013 to August 2018, tracheotomy combined with thyrocricocentesis and puncture of front tracheal wall was performed for 10 cases. Rescue effect and complication of the two kinds of tracheotomy were recorded. Data were processed with Fisher's exact probability test. Results: Among the 12 patients treated with simple emergency tracheotomy, 5 cases survived and 7 cases died of suffocation during tracheotomy. Among the 10 patients treated with tracheotomy combined with thyrocricocentesis and puncture of front tracheal wall, 9 cases survived and 1 case died of cardiac arrest caused by arrhythmia. There was statistically significant difference in successful rescue effect between the two kinds of tracheotomy (P<0.05). Among the 14 patients who were successfully rescued, symptoms of insomnia and post-traumatic stress disorder occurred in 12 cases, which were relieved after symptomatic treatment for 14 to 45 d without permanent hypoxic brain damage. Conclusions: In case of loss of the condition of preventive tracheotomy, first aid of acute laryngeal edema of burn patient is very difficult. Tracheotomy combined with thyrocricocentesis and puncture of front tracheal wall is simple and rapid with high successful rate and amelioration of hypoxia, which is an ideal plan for laryngeal edema.

Abstract
Objective: To study the expression level of monoacylglycerol lipase (MAGL) in liver tissues of patients with hepatocellular carcinoma (HCC), and its clinical correlation. Methods: Immunohistochemistry was employed to detect MAGL protein in 353 cases with hepatocellular carcinoma (HCC) and tissue microarray (TMA) for paracancerous liver tissues. The expression levels of MAGL in TMA were quantitatively analyzed using Image-Pro plus 6.0. The difference in MAGL expression between liver cancer tissues and paracancerous liver tissues was compared. Combined with the clinical follow-up data of TMA patients, the correlation between the expression of MAGL in TMA and the degree of HCC tumors differentiation and the survival rate of 1-year and 3-year were analyzed using Logistic regression analysis. The survival curves of patients with different levels of MAGL protein was plotted and analyzed using Kaplan-Meier method. The expression of MAGL protein was analyzed by multiple linear regression analysis. COX regression was used to analyze the correlation between MAGL protein expression level and the risk of HCC death in the included patients. Results: The expression of MAGL in HCC tissues was significantly higher than paracancerous liver tissues. The expression level of MAGL was correlated to the degrees of HCC tumors differentiation (P < 0.001) and 1-year survival rate (P = 0.01), but not with 3-year survival rate (P = 0.91). Survival curve showed that the expression level of MAGL was negatively correlated with prognosis and survival of HCC patients (P = 0.001). Multiple linear regressions showed a negative correlation between MAGL expression level and overall survival time of HCC patients (P=0.010, R2=0.166, Durbin-Watson value: 1.989). COX regression showed that the expression of MAGL was a risk factor for death of patients with HCC [P = 0.004, Exp (B) = 1.000]. Conclusion: The expression level of MAGL has positive correlation with the malignant degree in HCC patients, and negative correlation with its prognosis. Therefore, MAGL may serve as a new prognostic indicator for HCC patients.

Abstract
Carrier transport in AlGaN-based deep ultraviolet (DUV) light emitting diodes (LEDs) with the wavelength of 273 nm has been investigated by introducing polarization modulated electron blocking layer (EBL) that adopts an Al composition and thickness graded multiple quantum barriers (MQB) structure. The experimental result shows that the maximum light output power and external quantum efficiency for the proposed structure at the current of 250 mA are 9.6 mW and 1.03% respectively, severally increasing by 405% and 249% compared to traditional one, meanwhile, the efficiency droop at 250 mA is also dramatically reduced from 42.2% to 16.6%. Further simulation analysis indicates that this graded MQB-EBL enhances the potential barrier height for electrons and meanwhile reduces that for holes, hence effectively suppresses the electron leakage, and at the same time significantly improves the hole injection efficiency. As a result, the whole performance of the LED with the proposed MQB-EBL is dramatically improved.

Abstract
Objective: To investigate the effect of NACHT-LRR-PYD- containing proteins 3 (NLRP3) mediated pyroptosis in myocardial cells undergoing hypoxia/deoxygenation (H/R) injury. Methods: In order to observe whether H/R-treatment could cause pyroptosis, H9c2 cells were divided into 2 groups randomly using the lottery method: control group(without H/R-treatment) and H/R group (in which the H9c2 cells were underwent H/R-treatment). In order to clarify the role of pyroptosis in H/R-injury, H9c2 cells were divided into 4 groups randomly using the lottery method: control group(in which the H9c2 cells were cultivated with normal medium); YVAD group(in which the H9c2 cells were pretreated with z-Val-Ala-Asp(Ome)-fluoromethylketone (Z-YVAD-FMK) 20 μm for 4 hours, then replaced with normal medium); H/R group(H9c2 cells underwent H/R-treatment); YVAD+H/R group (in which the H9c2 cells were pretreated with 20 μm Z-YVAD-FMK for 4 hours before H/R-treatment). To determine whether H/R-induced cell pyroptosis is associated with NLRP3, H9c2 cells were divided into 4 groups randomly using the lottery method: control group (in which cells were transfected with a control nonspecific siRNA); si-NLRP3 group (in which cells were transfected with NLRP3-targeting siRNA); H/R group(in which cells were transfected with a control nonspecific siRNA before H/R-treatment); si-NLRP3+H/R group(in which the H9c2 cells were transfected with NLRP3-targeting siRNA before H/R-treatment). Pore formation on cell membrane was detected by propidium iodide (PI) staining. Cell viability was detected by CCK8 reagent. The protein expression of Caspase-1, interleukin-1β (IL-1β) and NLRP3 was detected by Western blot. Results: (1) The positive rate of PI staining ((26.46±5.15)% vs. (1.69±0.73)%,P<0.01), expression of NLRP3 (0.57±0.16 vs. 0.23±0.06,P<0.01), expression of Caspase-1 (1.07±0.13 vs. 0.37±0.08,P<0.01), and expression of IL-1β (0.38±0.08 vs. 0.16±0.05,P<0.01) were significantly higher in H/R group than in control group. (2)The cell vitality was significantly higher in YVAD+H/R group than in H/R group ((87.31±9.05)% vs. (73.30±7.19)%, P<0.05).The positive rate of PI staining was significantly decreased in YVAD+H/R group than in H/R group ((18.12±4.36)% vs. (26.45±4.60)%, P<0.05). The expression of Caspase-1 (0.72±0.12 vs. 1.07±0.15, P<0.05) and IL-1β(0.29±0.07 vs. 0.39±0.06, P<0.05) were significantly lower in YVAD+H/R group than in H/R group. (3) The cell vitality was significantly increased in si-NLRP3+H/R group than in H/R group ((85.46±7.71)% vs. (72.41±5.53)%, P<0.05). The positive rate of PI staining was significantly lower in si-NLRP3+H/R group than in H/R group ((18.22±4.20)% vs. (26.73±3.26)%, P<0.05). The expression of Caspase-1(0.87±0.07 vs. 1.15±0.15, P<0.05) and IL-1β(0.41±0.07 vs. 0.58±0.10, P<0.05) were significantly decreased in si-NLRP3+H/R group than in H/R group. Conclusion: NLRP3 mediated pyroptosis is involved in H/R injury of myocardial cells.

Abstract
Objective: To identify the pathogenic gene variants and clinical phenotype features of 26 children with progressive myoclonic epilepsy (PME). Methods: In this cross-sectional study, 26 PME children (11 boys and 15 girls) sent to neurological outpatient clinics and admitted to wards of the Department of Pediatrics, Peking University First Hospital were enrolled prospectively from January 2014 to October 2018. The pathogenic gene variants of PME children and their parents were identified by Sanger sequencing, next generation sequencing panels of epilepsy or trio-based whole exome sequencing and so on. The genotypes and phenotypes of the PME children were anaylzed. Results: The clinical features of 26 children include myoclonus, multiple types of seizures and progressive neurological regression. Their onset ages ranged from 3 months to 15 years. Several pathogenic gene variants were identified in the 15 patients, including TPP1 gene variantions in 3 patients; NEU1, GBA, TBC1D24 and KCNC1 gene variantions in 2 patients respectively; CLN6, MFSD8, ASAH1 and ATN1 gene variantions in 1 patient respectively. Several variants of uncertain significance were identified in 4 patients, including GOSR2 gene compound heterozygous variants in 2 patients, KCTD7 gene compound heterozygous variants in 1 patient, and compound heterozygous variants of an unreported TARS gene in 1 patient. No pathogenic gene variant was identified in 7 patients. In 15 children with the identified pathogenic gene variants, 5 patients were diagnosed with neuronal ceroid lipofuscinoses (NCL), 2 patients with sialidosis, 2 patients with neuronopathic Gaucher disease, 1 patient with dentatorubral-pallidoluysian atrophy (DRPLA), and 1 patient with spinal muscular atrophy-progressive myoclonic epilepsy (SMA-PME). Conclusions: PME include a group of diseases with genetic heterogeneity. Identification of the pathogenic gene variants of PME could help to predict the prognosis and guide the genetic counseling.

Abstract
Background: Activation of the clotting-fibrinolytic system in cancer patients is common and results in an unfavorable clinical outcome. This study aimed to investigate the role of pretreatment plasma D-dimer levels and the combination of D-dimer and albumin (DA) on the prediction of survival prognosis in patients with nasopharyngeal carcinoma (NPC). Methods: The study comprised 511 patients with NPC. Pretreatment plasma D-dimer and serum albumin levels were measured. DA was classified as a new biomarker where D-dimer and albumin levels were combined and was grouped by the cutoff value of both. The correlations of plasma D-dimer levels with clinicopathological features and survival outcome were calculated using the Chi-square test. Kaplan-Meier estimates were performed to analyze the survival functions and were compared using log-rank tests. Cox proportional hazard regression analysis was used to assess the effects of D-dimer and DA on distant overall survival (OS) and distant metastasis-free survival (DMFS). Results: The median follow-up period was 45.2 months (range 2.1-79.8). Elevated plasma D-dimer levels were positively associated with age at diagnosis (P = 0.034), platelet levels (P = 0.043), and Epstein Barr Virus (EBV) DNA copy number (P = 0.035). Additionally, multivariate analysis demonstrated that elevated plasma D-dimer levels were strongly associated with a poorer OS (HR 2.074, 95% CI 1.190-3.612, P = 0.010), but not DMFS. After adjustment for other variables, DA stratification acted as an independent prognostic marker for OS (P = 0.038) and DMFS (P = 0.031) in patients with NPC, when combined with albumin levels. Conclusions: Increased plasma D-dimer levels accurately predict poor OS and may be an effective independent prognostic factor in patients with NPC. Moreover, in conjunction with serum albumin, DA may serve as a factor in predicting OS and DMFS.

Abstract
Fever and abdominal pain are common symptoms and could be main manifestations in patients with autoinflammatory diseases. A 48-year-old female patient was admitted with recurrent fever and abdominal pain for 9 years. Serum level of inflammatory markers synchronously fluctuated with fever, and returned to normal when fever subsided. The periodic episodes of fever occurred every 1 to 4 months and failed to respond to empirical antibiotics. Whole exome sequencing showed heterozygous mutation of NOD2 gene q902k, leading to the final diagnosis of autoinflammatory disease. Corticosteroid and tripterygiumglycosides were effective for the disease remission.

Abstract
Objective: To summarize the phenotype of epileptic children with SCN2A mutations. Methods: Epileptic patients who were treated in the Pediatric Department of Peking University First Hospital from September 2006 to October 2017 and detected with SCN2A mutations by targeted next-generation sequencing were enrolled. Clinical manifestations of all patients were analyzed retrospectively. Results: A total of 21 patients (16 boys and 5 girls) with SCN2A mutations were collected. Twenty-one SCN2A mutations were identified. Ten patients had mutations inherited from one of their parents and 11 patients had de novo mutations. The age of epilepsy onset was from 2 days to 2 years and 6 months: six patients with seizure onset in neonates (29%) , six patients with seizure onset between 1 month and 3 months of age (29%), three patients with seizure onset between 4 months and 6 months of age, two patients with seizure onset between 7 months and one year of age, and four patients with seizure onset beyond one year of age. Multiple seizure types were observed. The focal seizure was the most common seizure type which was observed in 18 patients (86%) . Spasm seizure was observed in 6 patients (29%) . Other seizure types were rare. In 19 patients, seizures manifested in clusters (90%) . In 3 patients, seizures manifested fever-sensitive. Nine of ten patients with inherited SCN2A mutations had normal development. However, all patients with de novo SCN2A mutations had mild or severer development delay. In 21 patients with SCN2A mutations, five were diagnosed with benign familial infantile epilepsy, 3 with benign familial neonatal-infantile epilepsy, 3 with Ohtahara syndrome, 3 with West syndrome, 2 with encephalopathy with early infantile onset epilepsy, one with febrile seizures plus, one with Dravet syndrome, one with encephalopathy with childhood-onset epilepsy, one with autism with epilepsy and one with intellectual disability with epilepsy. Conclusions: The clinical features of patients with SCN2A mutations include that main seizure onset is the neonate and early infancy, and the main seizure type is the focal seizure, manifested in clusters. The large spectrum of SCN2A-related epilepsy, which not only includes epilepsy with a comparatively favorable prognosis, but also epileptic encephalopathy. De novo mutations often lead to severe phenotype with development delay.

Abstract
Objective: To investigate the effect of Baicalin on the expression of connexin 36 (Cx36) in cerebral cortex and striatum area of 6-OHDA-induced Parkinson's (PD) model rats and its significance. Methods: Male Sprague-Dawley (SD) rats were randomly divided into 6 groups, 12 in each group: normal control group, PD model group (untreated group), PD model (Medopa group), PD model (Baicalin low dose group) PD model (Baicalin medium dose group) and PD model (Baicalin high dose group). Except for the normal control group, 6-OHDA was injected using microinjection under the mouse brain stereotaxic apparatus to establish the hemiparkinsonian PD model. On the basis of the success of making model, the rats were treated by Medopa and Baicalin (low, medium and high dose). Immunohistochemistry was used to detect tyrosine hydroxylase (TH) and Cx36 expression in cerebral cortex and striatum of the 6 groups. Western-Blot technique was used to detect the cerebral cortex and striatum Cx36 expression changes, and to preliminarily study the effect of Baicalin on rat cerebral cortex and striatum Cx36 expression levels. Results: Immunohistochemical staining and Western blotting showed that the expression of TH-positive neurons and Cx36 in the cerebral cortex and striatum of the PD model group was lower than that of the normal control group (828±188). While expressions of Cx36 in the low, medium and high dose PD model groups of Baicalin (733±118, 759±134, 779±125) were up-regulated, compared with the untreated PD model group (487±125), and the differences were statistically significant (all P<0.05), but the difference between the doses was not statistically significant (P>0.05). Conclusion: The expression of Cx36 decreases in cerebral cortex and striatum area of 6-OHDA-induced Parkinson's disease model rats, and the expressions of TH and Cx36 in cerebral cortex and striatum increase after treatment with Baicalin, which may provide new drug research direction for Parkinson's disease.

Abstract
Objective: To explore the in vitro and in vivo effect of GP73 on the proliferation, invasion and metastasis in hepatocellular carcinoma. Methods: GP73 gene was knocked out using CRISPR/Cas9 gene editing system in H22 and HepG2 cells, and stable knock out strains were constructed. The knockout efficiency was measured by western blot. Colony formation assay was used to detect the effect of GP73 on long-term survival ability. Cells were then highly synchronized in G(1) phase upon treatment with cell synchronization reagents (mimosine), and the percentage of cells in G(2)/M phase at different time points was detected by flow cytometry. The invasive and metastasis abilities of hepatocellular carcinoma cells were detected by Transwell™ assay. Furthermore, the tumor formation abilities in vivo were examined using subcutaneous xenograft models. Results: The stable knock out strains of GP73 in H22 and HepG2 cells were successfully established via puromycin selection. The number of colonies of GP73 knock out groups in HepG2 and H22 cells 10 days after transfection were 400±70 and 248±60, respectively. They were significantly lower than those in the control groups (980±40 and 1 100±50, respectively; P<0.01). In addition, GP73 knockout slowed down the cell cycle progression. Moreover, the cell numbers that had migrated to the underside of the filters were 312±50 and 305±49 in the GP73 knockout groups of HepG2 and H22 cells, respectively, significantly lower than 1 540±87 and 1 270±86 in the controls (P<0.01). For transwell invasion assay, the cell number that had invaded into the underside of the filters were 230±47 and 238±54 in the GP73 knockout groups of HepG2 and H22 cells, respectively, significantly lower than 648±74 and 596±63 in the controls(P<0.01). Furthermore, the tumor volume of GP73 knockout group was (70±170) mm(3,) significantly smaller than (1 200±110)mm(3) of the control guoup (P<0.01). Conclusions: GP73 knockout decreases the proliferation, invasive and migratory abilities of HepG2 and H22 cells in vitro and in vivo. GP73 may contribute to tumorigenesis of hepatocellular carcinoma.
