Abstract
Light intensity is an important environmental factor that affects fish growth and health through multiple physiological activities and metabolism and eventually impacts aquaculture harvest. There is a need to evaluate the fish stress response to light intensities, which will benefit aquaculture. Here, hybrid grouper (Epinephelus lanceolatus ♂ × Epinephelus fuscoguttatus ♀) was treated with three light intensities for evaluation of the light stress response, including high light intensity (1 250 lx), low light intensity (10 lx) and moderate light intensity (250 lx). Transcriptome analysis showed that a total of 71 318 unigene sequences were obtained with an N50 of 2 589 bp. Compared to the control group (250 lx), 1 697 differentially expressed genes (DEGs), a considerable quantity, were detected in the 1 250 lx group. Among those genes, 548 were upregulated, and the remaining 149 genes showed decreased expression. Comparatively small numbers of DEGs were detected in the 10 lx group; 54 out of 103 genes exhibited upregulated expression, and 49 genes showed downregulation. For further KEGG analysis, 82 DEGs were enriched in nine common signalling pathways in immunity, of which 73 DEGs were significantly inhibited in the 1 250 lx group. In contrast, only 11 DEGs were enriched in three immunity pathways, with nine DEGs showing a significant increase in the 10 lx group. The metabolome analysis revealed 59 and 44 differential metabolites (DMs) from the 1 250 lx and 10 lx groups, respectively. Of note, those DMs from the 1 250 lx-treated group were tendentiously involved in amino acid metabolism and lipid metabolism pathways, while the purine metabolism, amino acid metabolism and lipid metabolism pathways were mostly found in the 10 lx treatment group. In summary, our data indicated that high light intensity significantly inhibited the immune response in hybrid grouper, while low light intensity presented low stimulation of immune activity. In addition, both high and low light intensity could inhibit protein synthesis and amino acid metabolism. Taken together, hybrid grouper exhibited a much milder stress response to low light intensity than to high light intensity.

Abstract
We examine temperature-dependent picosecond dynamics of two benchmarking proteins lysozyme and cytochrome c using temperature-dependent terahertz permittivity measurements. We find that a double Arrhenius temperature dependence with activation energies E1 ∼ 0.1 kJ/mol and E2 ∼ 10 kJ/mol fits the folded and ligand-free state response. The higher activation energy is consistent with the so-called protein dynamical transition associated with beta relaxations at the solvent-protein interface. The lower activation energy is consistent with correlated structural motions. When the structure is removed by denaturing, the lower-activation-energy process is no longer present. Additionally, the lower-activation-energy process is diminished with ligand binding but not for changes in the internal oxidation state. We suggest that the lower-energy activation process is associated with collective structural motions that are no longer accessible with denaturing or binding.

Abstract
Abstract
Background
The association between international normalized-ratio (INR) and long-term prognosis among patients with coronary artery disease (CAD) without atrial fibrillation (AF) or anticoagulant therapy was still unclear. We analyzed the association of INR levels and long-term mortality in a large cohort of CAD patients without atrial fibrillation or using of anticoagulant drugs.
Method
We obtained data from 44,662 patients who were diagnosed with CAD and had follow-up information from January 2008 to December 2018. The patients were divided into 4 groups (Quartile 1: INR ≤0.96; Quartile2: 0.961.06). The main endpoint was long-term all-cause death. Kaplan-Meier curve analysis and Cox proportional hazards models were used to investigate the association between quartiles of INR levels and long-term all-cause mortality.
Result
During a median follow-up of 5.25 years, 5,613 (12.57%) patients died. We observed a non-linear shaped association between INR levels and long-term all-cause mortality. Patients in high INR level (Quartile4: INR >1.06) showed a significantly higher long-term mortality than other groups (Quartile2 or 3 or 4), (Compared with Quartile 1, Quartile 2 [0.961.06], aHR=1.33, 95% CI: 1.22–1.45, P<0.05).
Conclusion
Our study demonstrates high levels of INR were associated with an increased risk of all-cause mortality.

Abstract
Objective: To report the risk factors, clinical characteristics and treatment courses of pulmonary mucormycosis after lung transplantation(LT). Methods: We included 3 cases with pulmonary mucormycosis after LT from March 2017 to July 2020 in the centre for lung transplantation of China-Japan Friendship Hospital. Twelve cases from Chinese and English literature from China National Knowledge Infrastructure (CNKI), China Biomedical Literature Service System and Pubmed Database from March 1980 to July 2020 were added. The risk factors, clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Pulmonary mucormycosis occurred in 1.06% (3/284) in our centre. A total of 15 cases with 12 cases from literature included 10 males and 5 females with a mean age of(47±20)years. Thirteen cases occurred after LT, and 2 cases occurred after heart-lung transplantation (HLT). Nine probable cases were diagnosed by positive isolation of the pathogen from bronchoalveolar lavage fluid or sputum. Three proven cases were diagnosed by transbronchial lung biopsy. Meanwhile, the other 3 proven cases diagnosed by CT-guided percutaneous lung biopsy, autopsy and surgical operation respectively. Ten cases (66.7%) were diagnosed with pulmonary mucormycosis within 90 days after lung transplantation. The mortality was as high as 46.67% (7/15), but if it occurred within 90 days, the mortality reached 70% (7/10). The average interval between transplantation and positive isolation of the pathogen was 112.3 (5-378) days. Conclusions: The clinical and radiographic features of pulmonary mucormycosis after LT were nonspecific. It had a high mortality, especially in those occurred within 90 days after LT. The combination of antifungal therapy and surgical resection may contribute to a better outcome of the disease.

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
Objective: To analyze the clinical efficacy and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH-a) based fertility-sparing re-treatment in women with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) who failed with oral progestin therapy. Methods: Forty cases with EC or AEH who failed to respond to oral progestin were included from January 2012 to December 2020 at Peking Union Medical College Hospital. Combination of GnRH-a with levonorgestrel-releasing intrauterine system (group GLI: a subcutaneous injection of GnRH-a every 4 weeks and LNG-IUS insertion constantly) or the combination of GnRH-a with aromatase inhibitor (group GAI: a subcutaneous injection of GnRH-a every 4 weeks and oral letrozole 2.5 mg, daily) were used for these patients. Histological evaluation were performed at the end of each course (every 3-4 months) by hysteroscopy and curettage. After the complete remission (CR), all patients were followed up regularly. Results: (1) Clinical characteristics:among the 40 patients with EC or AEH, the median age at diagnosis was 31 years (range: 22-40 years) and the median body mass index was 24.7 kg/m2 (range: 18.9-39.5 kg/m2). (2) Efficacy of fertility-sparing re-treatment: 37 (92%, 37/40) patients achieved CR, 6 (6/7) in AEH and 31 (94%, 31/33) in EC patients. The CR rate was 93% (26/28) and 11/12 in group GLI and GAI, respectively. The median time to CR was 5 months (range: 3-12 months). At the end of the first therapy course, the CR rates in AEH and EC were 5/7 and 42% (14/33), at the second course, the CR rates were 6/7 and 82% (27/33), respectively. (3) Recurrence: after 25 months of median follow-up duration (range: 10-75 months), 8 (22%, 8/37) women developed recurrence, 1/6 in AEH and 7 (23%, 7/31) in EC patients, with the median recurrence time of 18 months (range: 9-26 months). Among them, two cases who had completed childbirth chose to receive hysterectomy directly. Six patients met the criteria of fertility-preserving therapy and received conservative treatment again and 5 (5/6) of them achieved CR. (4) Pregnancy: of the 37 patients with CR, 33 desired to conceive. Ten women attempted to get pregnancy spontaneously and 23 cases with assisted reproductive technology. Fourteen (42%, 14/33) patients became pregnant, including 9 (27%, 9/33) live births, 3 (9%, 3/33) missed abortions, and 2 (6%, 2/33) miscarriages at the second trimester. Conclusions: GnRH-a based fertility-sparing re-treatment in AEH or EC patients who failed with oral progestin therapy achieved good treatment effect and reproductive outcomes. It is an encouraging alternative regime for patients who failed with oral progestin therapy.

Abstract
Objective: To investigate the feasibility of endoscopic lateral neck dissection via the breast and transoral approaches (ELNDBTOA) for papillary thyroid carcinoma (PTC). Methods: From February 2015 to April 2019, 10 patients with PTC (cN1b) including 1 male and 9 females aged from 22 to 53 years old received ELNDBTOA in the General Surgery Department of Zhongshan Hospital, Xiamen University. Total thyroidectomy, the central lymph node dissection and the selective neck dissection (levels Ⅱ, Ⅲ and Ⅳ) were performed endoscopically via the breast approach, and then the residual lymph nodes were dissected via transoral approach. The medical records, operation time, blood loss, complications and postoperative follow-up outcomes were analyzed retrospectively. SPSS 22.0 software package was used for statistical processing of clinical data of patients. Results: All cases were successfully treated with ELNDBTOA without transfer to open surgery. The average operative time was (362.5±79.7) min, the blood loss was (23.0±14.9) ml, and the postoperative hospital stay was (5.1±1.3) days. The mean number of harvested cervical lymph nodes were (34.2±25.8), and the mean number of positive lymph nodes were (6.5±4.9). Lymph nodes were dissected by the further dissection via oral approach in 6 patients and a total of 9 lateral lymph nodes were havested from 2 of the 6 patients, with 3 positive lymph nodes. Two patients had transient skin numbness in the mandibular area and recovered within two weeks. One patient developed transient hypoparathyroidism and recovered within two months. No secondary bleeding, recurrent laryngeal nerve paralysis, chylous leakage, neck infection, permanent hypoparathyroidism or other complications were observed. The follow-up time was from 16 to 66 months with a median of 42.5 months, no tumor recurrence or metastasis occurred, and also no obvious deformity, abnormal sensation or movement in the chest, neck and mouth was observed. Conclusions: ELNBTOA is safe and feasible, with good cosmetic outcome.

Abstract
Objective: To explore the association between rare UBQLN2 variants and amyotrophic lateral sclerosis (ALS) in Chinese population, and the characteristic of phenotypes of their carriers. Methods: A total of 166 ALS patients who visited Department of Neurology of Peking University Third Hospital between January 2018 and July 2020 were recruited. The next-generation sequencing was performed to screen possible pathogenic rare variants of UBQLN2. Meanwhile, control individuals were obtained from 1000 Genome Project (2 504 samples) and an in-house whole-exome sequencing database (1 812 samples), separately. The sequence kernel association test (SKAT) and the SKAT-optimal test (SKAT-O) were used to identify the association between UBQLN2 rare variants and ALS. The clinical characteristics of rare variant carriers were analyzed. Results: A total of 33 familiar ALS and 133 sporadic ALS of Chinese ancestry were enrolled. Of the 166 ALS patients, 12.7% had bulbar-onset, 85.5% had limb-onset, and 5 cases were ALS with frontotemporal dementia (3.0%). The male-to-female ratio was 1.68∶1, with a mean age at symptom onset of (43.8±12.2) years. Three possible pathogenic rare variants of UBQLN2 were detected, including c.128A>G (p.Lys43Arg), c.142G>T (p.Val48Leu) and c.1451T>G (p.Val484Gly), and all of them were novel missense mutations. Compared with 1000 Genome Project, SKAT and SKAT-O showed a P value of 2.49×10-6 and 9.22×10-7, respectively. While compared with the in-house database, SKAT and SKAT-O revealed a P value of 1.42×10-3 and 1.10×10-3, respectively. Patients who carried rare UBQLN2 variants were with a higher rate of bulbar-onset (2/3 vs 19/163, P=0.042). Conclusion: Rare variants of UBQLN2 are associated with ALS in Chinese population, and mutation of UBQLN2 may be relevant to bulbar-onset.

Abstract
Most oral squamous cell carcinoma (OSCC) tumors arise from oral premalignant lesions. Oral submucous fibrosis (OSF), usually occurring in male chewers of betel quid, is a premalignant stromal disease characterized by a high malignant transformation rate and high prevalence. Although a relationship between the inhabited microbiome and carcinogenesis has been proposed, no detailed information regarding the oral microbiome of patients with OSF exists; the changes of the salivary microbiome during cancer formation remain unclear. This study compared the salivary microbiomes of male patients with OSCC and a predisposing OSF background (OSCC-OSF group) and those with OSF only (OSF group). The results of high-throughput sequencing of the bacterial 16S rRNA gene indicated that OSF-related carcinogenesis and smoking status significantly contributed to phylogenetic composition variations in the salivary microbiome, leading to considerable reductions in species richness and phylogenetic diversity. The microbiome profile of OSF-related malignancy was associated with increased microbial stochastic fluctuation, which dominated the salivary microbiome assembly and caused species co-occurrence network collapse. Artificial intelligence selection algorithms consistently identified 5 key species in the OSCC-OSF group: Porphyromonas catoniae, Prevotella multisaccharivorax, Prevotella sp. HMT-300, Mitsuokella sp. HMT-131, and Treponema sp. HMT-927. Robust accuracy in predicting oral carcinogenesis was obtained with our exploratory and validation data sets. In functional analysis, the microbiome of the OSCC-OSF group had greater potential for S-adenosyl-l-methionine and norspermidine synthesis but lower potential for l-ornithine and pyrimidine deoxyribonucleotide synthesis and formaldehyde metabolism. These findings indicated that the salivary microbiome plays important roles in modulating microbial metabolites during oral carcinogenesis. In conclusion, our results provided new insights into salivary microbiome alterations during the malignant transformation of OSF.

Abstract
We measured missing mass spectrum of the ^{12}C(γ,p) reaction for the first time in coincidence with potential decay products from η^{'} bound nuclei. We tagged an (η+p) pair associated with the η^{'}N→ηN process in a nucleus. After applying kinematical selections to reduce backgrounds, no signal events were observed in the bound-state region. An upper limit of the signal cross section in the opening angle cosθ_{lab}^{ηp}<-0.9 was obtained to be 2.2 nb/sr at the 90% confidence level. It is compared with theoretical cross sections, whose normalization ambiguity is suppressed by measuring a quasifree η^{'} production rate. Our results indicate a small branching fraction of the η^{'}N→ηN process and/or a shallow η^{'}-nucleus potential.

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 examine the effectiveness of non-operative of colonic fistula following acute pancreatitis. Methods: Retrospective analysis of 354 patients with acute pancreatitis who were admitted to Department of Hepatobiliary Surgery of Chinese People's Liberation Army General Hospital from January 2013 to December 2018. Age of the patients was (46±14) years (range: 14-85 years); 249 cases (70.3%) were males. There were 41 cases of acute edematous pancreatitis and 313 cases of acute necrotising pancreatitis. Two hundred and fifteen cases were diagnosed as moderate severe acute pancreatitis and 139 were diagnosed as severe acute pancreatitis. Among 313 cases of acute necrotising pancreatitis, 62 cases underwent non-surgical treatment, 251 cases underwent surgical treatment in which 218 of minimal access retroperitoneal pancreatic necrosectomy underwent percutaneous nephroliguectomy with peripancreatic necrotic tissue removal technique. Results: There were 15 cases of colon fistula following acute necrotising pancreatitis, and the incidence rate was 4.2%(15/354). There were 7 males and 8 females, with age of (39±8) years (range: 27 to 50 years). The median interval between acute pancreatitis onset and diagnosis of colonic fistula was 71 days(27-134) days. Two cases occurred at the hepatic flexure of the colon, 4 cases at transverse colon, and 9 cases at splenic flexure of colon. Of the 354 patients, 39 cases died and the mortality was 11.0%. Two patients underwent laparotomy, and one of them died. The remaining 13 patients underwent non-surgical treatment and were discharged. Conclusion: Acute pancreatitis with colonic fistula can be treated with non-surgical treatment and can achieve good prognosis.

Abstract
Abstract
Background
There is a growing prevalence of diabetes worldwide in patients in the general population, including those with prior myocardial infarction (MI).
Purpose
To describe the characteristics, health status, resource utilization and clinical adverse events of stable post-MI patients with diabetes.
Methods
The long-Term rIsk, clinical manaGement and healthcare Resource utilization of stable coronary artery dISease (TIGRIS) prospective observational study (NCT01866904) obtained data from 8985 stable patients 1–3 years post-MI from 369 centres in 25 countries, who provided diabetes status (no, yes, insulin-treated) and follow-up. Diabetes status, other patient characteristics, medications, medical history and healthcare resource utilization were recorded at enrolment. Health status was assessed at enrolment, 1 and 2 years by EQ-5D-3L and converted to an EQ-5D score. Deaths, cardiovascular (CV) events, bleeding events and related hospitalizations were recorded during 2 years of follow-up.
Results
Diabetes mellitus (DM) was prevalent at enrolment in 2966 (33%) patients of whom 872 (29%) were insulin-treated. Compared to patients without DM, those with DM had a higher mean body mass index (28.2 vs 26.6kg/m2) and heart rate (71 vs 67bpm), were more likely to have had ≥2 prior MIs (12% vs 10%), chronic kidney disease (10% vs 6%), peripheral artery disease (10% vs 5%), heart failure (15% vs 10%), anaemia (4% vs 2%), angina (12% vs 9%), stroke (6% vs 4%) and chronic obstructive pulmonary disease (9% vs 7%). Patients with DM reported more problems for each domain of the EQ-5D (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), which resulted in a lower mean EQ-5D utility score at enrolment (0.83±0.22 for no-diabetes vs 0.86±0.19 for diabetes). Moreover, they also had higher CV hospitalization rates in the 6 months prior to enrolment (6.4% vs 5%). All these measures were more marked in insulin-dependent diabetics. The incidences of all-cause death, CV death and the composite of CV death, MI and stroke were all significantly higher in patients with DM, especially those on insulin (see Figure). For CV death, MI and stroke the 2-year risk ratios, compared to patients without DM, were 2.64 (P<0.001) and 1.48 (P<0.001) respectively for those with insulin-treated DM and non-insulin treated.
Figure 1
Conclusions
Within a global population of stable post-MI patients, those with DM (especially those on insulin) have poorer health status and EQ-5D utility score, higher hospitalization rates and worse clinical outcomes compared with those without DM. Thus, in cardiac clinics worldwide, patients with DM require particularly close attention.

Abstract
Objective: To investigate the microbiological test, antibiotic sensitivity and surgical treatment of periprosthetic joint infection(PJI) cases in post total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Methods: A retrospective cross-sectional survey was conducted on 318 patients who underwent THA or TKA in 9 clinical centers in Beijing from January 2014 to December 2016.The data of microbiology, antibiotic sensitivity and surgical treatment were collected.The average age of patients was (62.3±13.1) years old (range: 21-86 years old), including 145 males and 173 females.The body mass index was (25.6±3.8) kg/m (2) (range: 15.6-38.1 kg/m(2)). Results: In total, 318 patients had microorganisms detected by periprosthetic tissue culture or synovial fluid culture, 209 cases (65.7%) had Gram-positive bacteria, 29 cases (9.1%) had Gram-negative bacteria, 10 cases (3.1%) had fungi, 3 cases (0.9%) had non-tuberculous mycobacteria, 72 cases (22.6%) were negative, 69 cases (21.7%) had methicillin-resistant bacteria. The antibiotic sensitivity results showed that the overall resistance rate of penicillin, cefuroxime, amoxicillin+clavulanic acid was 79.9%, 69.9%, and 68.1%, respectively; meropenem, vancomycin, and linezolid resistance rate was 0. For the treatment methods of hip and knee PJI, two-stage revision surgery acounted for 72.9% (108/148) and 64.1% (109/170), respectively. One-stage revision surgery accounted for 21.6% (32/148) and 7.6% (13/170), and open debridement surgery accounted for 4.7%(7/148) and 26.4% (45/170). Conclusions: Gram-positive bacteria was still the main pathogen of PJI.The methicillin-resistant bacteria and rare bacteria should be payed attention to. The Majority of hip and knee PJI cases were treated by two-stage revision surgery.

Abstract
Objective:The aim of this study is to investigate the use of CT, magnetic resonance imaging (MRI), functional magnetic resonance (fMRI) and electrical evoked auditory brainstem response in children with cochlear nerve deficiency (CND) before cochlear implantation (CI) (electrically evoked auditory brain stem response, EABR) evaluated auditory pathway, auditory cortex function, and cochlear nerve function. Method:Of 6 children with bilateral profound sensorineural hearing loss, bilateral internal auditory meatus stenosis was diagnosed by CT as in 4 cases and unilateral internal auditory meatus stenosis in 1 case. In 3 cases, oblique sagittal MRI reconstruction of the internal auditory meatus showed only facial nerve and vestibular nerve existence. 6 cases were diagnosed as CND by imaging, among which underwent fMRI and EABR in 3 cases, respectively. All the children received unilateral CI and were followed up for at least 1 year after hearing and speech rehabilitation. Result:fMRI was examed in 3 cases with CND. It showed that the right auditory cortex was activated in 1 case after sound given to the left ear but no activation was found in the left cortex when sound given to the right ear. 1 case showed activation in bilateral transverse temporal gyrus while sound was given to the left, right and both ears at 2000Hz. Another case had no activation in both auditory cortex. EABR detection elicited V wave in 2 of 3 cases. 6 children received audiological and speech evaluation 1 month, 6 and 12 months after CI. Among them, the hearing level was improved within 6 months after surgery in 4 cases, and the threshold of sound field was (48.15±6.60) dB HL, MAIS and CAP scores were improved. However, SIR score improvement is limited in 3 cases. The hearing level was improved in 1 case, but speech rehabilitation was poor mainly due to the older age. Conclusion:Preoperative comprehensive application of imaging and electrophysiological evaluation of children with CND can more accurately assess the integrity of the auditory pathway and understand the function of the cochlear nerve. It has important reference significance for whether or not to perform surgery. There was a significant difference in auditory speech rehabilitation after CND in children with CND.

Abstract
Objective: To investigate the incidence of venous thromboembolism (VTE) in lung transplant (LT) recipients. Methods: The clinical data on 124 consecutive patients who underwent lung transplant at Lung Transplantation Center of China-Japan Friendship Hospital from March 2017 to September 2018 were retrospectively collected. Deep venous thrombosis (DVT) was ascertained by vascular ultrasound. Pulmonary embolism (PE) was diagnosed by either chest computed tomography pulmonary angiogram or ventilation/perfusion scan. The risk factors in those patients with postoperative VTE were studied. Results: A total of 124 lung transplant recipients including 78 single lung transplant recipients (62.9%) and 46 bilateral lung transplant recipients(37.1%) were enrolled. Preoperative and postoperative prophylactic anticoagulant was used in 52 patients(52/124, 41.9%) and 69 patients(69/124, 55.6%) respectively. Thirty-two patients developed postoperative VTE among 124 consecutive patients. The overall incidence rate of VTE among 124 LT recipients was 25.8%. The median time to VTE episode following lung transplant was 22.5 days (range 4-295 days). The percentage of DVT in VTE was 93.8%(30/32), involving 1-8 (2.83±1.86) veins. And 60.0% of DVT was from lower extremities and 56.7% located in upper extremities (P>0.05). Four patients (4/32,12.5%) had PE episodes, and half of them suffered from only PE without DVT. The use of extracorporeal membrane oxygenation (ECMO) in 32 patients with VTE was 90.6% (29/32), which was significantly higher than that without VTE (64/92,69.6%, P=0.033). However, there was no difference in the use of peripherally inserted central catheter (PICC) between two groups (96.9% vs 81.5%, P=0.067). Resolution of VTE was successfully accomplished by anticoagulant therapy with long-term use of low molecular weight heparin in 30 patients (93.7%) and followed by oral warfarin in 2 patients (6.3%). Three months follow-up data after anticoagulant therapy showed that total and partial vascular recanalization rate was 65.6%(21/32) and 34.4%(11/32), respectively. Despite anticoagulation-related bleeding complications in three patients, no serious consequences occurred. Conclusions: VTE was frequent in LT recipients. It was speculated that ECMO utilization may be a major risk factor for high incidence of VTE in LT recipients. Aggressive VTE screening/treatment protocols were suggested to be implemented in LT recipients.

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
Objective:This study was to analyze the results of video head impulse test (vHIT) of benign paroxysmal vertigo of childhood (BPVC) in order to determine the potential value of vHIT in the diagnosis and treatment for BPVC and to discuss its possible pathogenesis of BPVC. Method:Thirty-six children with BPVC were enrolled. No hearing loss and skull abnormality were found in these children as assessed by pure tone audiometry, acoustic impedance, CT or MRI scan. The vHIT was carried out, and main outcome measures were the gain of vestibulo-ocular reflex, gain asymmetry, and refixation saccades. Eleven healthy children were selected as normal control who came to our hospital for doing a routine checkup and have no history of dizziness. The differences of vHIT results between these two groups were analyzed. Result:①The vHIT results in control group were normal. In all BPVC subjects, abnormalities were detected in 9 patients (25.0%),including vHIT gains decline in 3 patients, abnormal symmetry in 4 patients, and abnormal isolated overt saccades in 2 patients.②The average saccadic gain in different canals of BPVC group was 1.03±0.14, 1.01±0.15, 1.13±0.31, 1.18±0.36, 1.21±0.33, 1.14±0.30 in left horizontal, right horizontal, left anterior, right posterior, right anterior, left posterior canal, respectively; while in normal group, it was 1.14±0.15, 1.18±0.09, 1.16±0.30, 1.18±0.40, 1.34±0.26, 1.30±0.20, respectively. Significant statistical difference was found only in horizontal canals between these two groups (P<0.05). ③Asymmetry of the three pairs of conjugated semicircular canals was 0.04±0.07 (horizontal canal), 0.06±0.04 (left anterior and right posterior canal), 0.06±0.04 (right anterior and left posterior canal) in BPVC group, respectively; while in control group, it was 0.02±0.02, 0.04±0.03, 0.04±0.04,respectively. There was no statistical difference between the two groups (P>0.05). Conclusion:A certain proportion of abnormal peripheral vestibule function in children with BPVC was found. vHIT is a "child friendly," relatively easytouse, and simple tool to evaluate each of the 6 semicircular canals, which may offer some potential clinical information for assessing the vestibule dysfunction for BPVC.

Abstract
Objective: To analyze the incidence and influencing factors of venous thromboembolism (VTE) after lung transplantation. Methods: This study retrospectively analyzed the clinical data of 375 lung transplant patients from January 2015 to December 2017 in Wuxi People's Hospital. Every patient was classified into the VTE group or the non-VTE group according to whether the patient had VTE or not. Basic information like age, type of surgical procedure etc. was compared between two groups. The prevention and treatment of VTE between two groups were also compared. Furthermore, multivariate Logistic regression analysis was used to analyze the influence of related factors on the occurrence of postoperative VTE. Deep venous thrombosis (DVT) was diagnosed with vascular ultrasonography, and pulmonary thromboembolism (PTE) was diagnosed with CT pulmonary angiogram, nuclear ventilation/perfusion scanning, or pulmonary angiography. Results: This study included 316 lung transplant patients. VTE occurred in 19 patients (6.0%) during perioperative and follow-up period. The age of the VTE group was significantly higher than that of the non-VTE group (63.4±11.9 vs 54.3±13.0, P=0.003). The proportion of single lung transplantation in the VTE group was significantly higher than that in the non-VTE group (78.9% vs 48.5%, P=0.010). The incidence of VTE in patients without prevention was significantly higher than that in patients with prevention (15.0% vs 1.9%, P<0.001). Single lung transplantation (OR=4.425, P=0.018), duration in intensive care unit (ICU) (OR=1.396, P=0.001) and age (OR=1.080, P=0.005) were independent risk factors for VTE after lung transplantation. Conclusions: The incidence of VTE after lung transplantation is high. Single lung transplantation, prolonged duration of ICU stay and advanced age increase the risk of VTE after lung transplantation.

Abstract
Objective: To discuss the benefit of using transmastoid slotted labyrinthotomy approach (TSLA) and customized electrode for common cavity deformity (CCD) patients, and to evaluate the audiological outcomes. Methods: A retrospective analysis of the intraoperative monitoring data and postoperative auditory outcomes of 10 CCD cases who received cochlear implantation in Beijing Tongren Hospital,Capital Medical University from April 2016 to December 2017, was conducted using TSLA and customized electrod as a test group.At the same time, 10 cases of age and gender matched children with severe or severe sensorineural hearing loss and normal inner ear structures were recorded as a control group. Four questionnaires were collected from the two groupspre-operative, 6 months and 1 year after start-up. The Wilcoxon signed rank sum test was used to compare the scores of different time points. Rank sum test of two independent samples was used to compare the scores between different groups. Results: None of the patients exhibited CSF leakage or facial paralysis after operation. The average impedance of 8 CCD children in the experimental group was below 5 kΩ. The total extraction rate of auditory neural response telemetry (ART) of all stimulating electrodes was 55% (33/60), and the amplitude of the electricity induced complex action potential (ECAP) of electrodes at different positions ranged from 50.69 to 170.3 μV.The average surgical time of the TSLA group was 46.4 min, shorter than the traditional approach.There was significant difference between the scores of pre-operative, 6 months and 1 year after start-up for the TSLA group(categories of auditory performance,CAP: 2.0 (2.0,3.0) vs. 4.0 (3.8,4.0) , Z=-3.109, P=0.002; speech intelligibility rating,SIR: 2.0 (2.0,2.3) vs. 3.0 (2.8,4.0) , Z=-2.952, P=0.003; meaningful use of speech scale,MUSS: 4.0 (3.3,6.0) vs. 9.0 (6.0,11.8) , Z=-3.421, P=0.001; meaningful auditory integration scale, MAIS or infant-toddler and meaningful auditory integration scale, IT-MAIS: 5.5 (3.8,9.0) vs. 15.5 (10.8,18.5) , Z=-3.522, P=0.000 for the latter two).In addition, The scores of the TSLA group were significantly worse than the control group at 6 months and 1 year after start-up.The high-resolution CT scan showed good adhesion of the electrodes without displacementone week and one year after surgery. Conclusions: For CCD patients, TSLA and customized electrode is recommended due to lower surgical difficulty and post-operative risk, shortened surgical time; Intraoperative ART monitoring can be used to determine the integrity of the auditory pathway. Children with common cavity deformity have a longer period of auditory rehabilitation, and the individual differences in speech rehabilitation are significantly different, which is significantly worse than those with normal structure.
