Abstract
Objective: To investigate the clinical characteristics of children with early-onset necrotizing enterocolitis (NEC) undergoing enterostomy and analyze the risk factors for postoperative complications. Methods: Retrospective analysis was conducted on the clinical data (perinatal conditions, clinical characteristics, clinical outcomes, etc.) of NEC patients who underwent enterostomy at Beijing Children's Hospital from May 2016 to May 2023. The patients were divided into two groups based on the age of onset: an early-onset enterostomy group (<14 days) and a late-onset enterostomy group (≥14 days). Furthermore, the children with NEC were categorized into complication group and non-complication group based on whether there were complications after enterostomy. The differences in clinical data between these groups were analyzed, and the clinical characteristics of children with early-onset NEC and enterostomy were summarized. Multivariate logistic regression model was employed to analyze the risk factors for postoperative complications in NEC children with enterostomy. Results: A total of 68 cases were enrolled, including 43 cases in the early-onset enterostomy group [26 males and 17 females, aged (6.5±3.0) days] and 25 cases in the late-onset enterostomy group [15 males and 10 females, aged (21.0±3.0) days]. There were 28 cases (17 males and 11 females), age [M (Q1, Q3)] 9 (5, 14) days in the complication group and 33 cases (22 males and 11 females), aged of 14 (6, 21) days in the non-complication group. Compared to the late-onset enterostomy group, the early-onset enterostomy group had significantly higher rates of intraventricular hemorrhage [30.2% (13/43) vs 8.0% (2/25)], hemodynamically significant patent ductus arteriosus [37.2% (16/43) vs 12.0% (3/25)], mechanical ventilation≥72 hours after birth [39.5% (17/43) vs 16.0% (4/25)], stage Ⅲ NEC [(69.8% (30/43) vs 40.0% (10/25)], extensive NEC [27.9% (12/43) vs 8.0% (2/25)], and short-term postoperative complications [56.8% (21/37) vs 29.2% (7/24)] (all P<0.05).Multivariate logistic regression model analysis revealed that residual length of proximal small intestine was a protective factor for postoperative complications after enterostomy in NEC infants (OR=0.764, 95%CI: 0.648-0.901, P=0.001), but stage Ⅲ NEC was a risk factor (OR=1.042, 95%CI: 1.004-5.585, P=0.017). Conclusions: The incidence of postoperative complications is high, and the prognosis is poor in children with early-onset NEC enterostomy. The residual length of proximal enterostomy is a protective factor for postoperative complications of NEC enterostomy, but stage Ⅲ NEC is a risk factor.

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
Objective: To investigate the clinical diagnostic value of multi-target stool fecal immunochemical test-DNA (FIT-DNA) test in colorectal cancer (CRC) and advanced adenoma (AA). Methods: A total of 235 patients who were undergoing colonoscopy or colorectal cancer surgery in the Cancer Hospital, Chinese Academy of Medical Sciences from April 2021 to January 2022 were prospectively enrolled. There were 141 males and 94 females, with an average age of (55±13) years (22-86). The patients were divided into two groups, including 215 patients who were first diagnosed but not treated (86 cases of CRC, 12 cases of AA, 25 cases of non-advanced adenoma, 8 cases of hyperplastic or other polyps and 84 apparently healthy cases) and 20 patients in the intervention group (2 cases with a history of CRC surgery, 6 cases with a history of endoscopic surgery, 4 non-CRC patients with special diseases and 8 cases with a history of neoadjuvant chemoradiotherapy). Fresh stool samples were collected before intestinal preparation or surgery for FIT-DNA test using the matching kit for sample processing and nucleic acid purification. KRAS mutation and methylation of BMP3 and NDRG4 genes were detected by fluorescence probe method, and FIT method was employed to detect fecal occult blood. Colonoscopy or pathological biopsy results were used as the gold standard. And the screening and diagnostic efficacy of FIT-DNA test for colorectal cancer and advanced adenoma were evaluated by receiver operating curve (ROC). Results: The sensitivity of FIT-DNA test for early colorectal cancer and advanced adenoma was 7/7 and 8/12, respectively. And the negative predictive value was 98.1% (104/106) and 93.7% (104/111), respectively. The overall screening sensitivity for both early colorectal cancer and advanced adenoma was 15/19, and the negative predictive value was 96.3% (104/108). Besides, the area under the curves (AUCs) were 0.982 (95%CI: 0.960-1.000, P<0.05), 0.758 (95%CI: 0.592-0.924, P<0.05) and 0.841 (95%CI: 0.724-0.957, P<0.05), respectively. Moreover, the diagnostic sensitivity of FIT-DNA test was 98.8% (85/86) for colorectal cancer, 8/12 for advanced adenoma, and 94.9% (93/98) for both colorectal cancer and advanced adenoma, with a specificity of 88.9% (104/117). The AUCs were 0.968 (95%CI: 0.937-0.997, P<0.05), 0.758 (95%CI: 0.592-0.924, P<0.05) and 0.942 (95%CI: 0.905-0.979, P<0.05), respectively. After the inclusion of intervention group, the overall diagnostic sensitivity and specificity of FIT-DNA test was 91.6% (98/107) and 89.1% (114/128), respectively. Conclusion: FIT-DNA test has a high early screening and diagnostic efficacy for colorectal cancer.

Abstract
Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ2=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ2=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ2=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.

Abstract
Objective: To study the protective effect and mechanism of paeoniflorin (pae) on myocardial injury in septic rats. Methods: Sprague-Dawley (SD) rats were randomly divided into 4 groups with 10 rats in each group. Rats were intraperitoneally injected with 1.4 ml normal saline and 1.4 ml 5% dimethyl sulfoxide (DMSO)solution independently in control group and DMSO group. Rats were intraperitoneally injected with 1.4 ml normal saline and 1.4 ml pae independently, then with 0.1 ml lipopolysaccharide (LPS) 1 hour later in sepsis group and pae group. Enzyme linked immunosorbent assay (ELISA) was used to detect serum cardiac troponin I (cTnI) levels and myocardial tissue tumor necrosis factor alpha (TNFα), interleukin(IL)-6, IL-1β, chemokine (C-X-C motif) ligand 1 (CXCL1), chemokine (C-X-C motif) ligand 2 (CXCL2), vascular cell adhesion molecule 1 (VCAM-1) levels. Evans blue (EB) method was used to detect the EB content of myocardial tissue. HE staining method was used to observe the pathological changes, real-time quantitative polymerase chain reaction (RT-qPCR) to detect mRNA expression levels of the above molecules, and Western-blot to detect vascular endothelium-cadherin (VE-cadherin), phosphorylated p38 mitogen-activated protein kinase (P-p38MAPK), phosphorylated Src protein (P-Src), Ras-Related C3 Botulinum Toxin Substrate 1 (Rac1) levels. Results: Compared with control group, cTnI level and the EB content in sepsis group increased significantly, and the myocardial inflammatory cell infiltration was obvious. The cTnI level and EB content in pae group were significantly reduced, and myocardial inflammatory cell infiltration was reduced [cTnI: (227.7±15.9)pg/ml vs. (312.9±17.9)pg/ml;EB: (13.2±2.3)μg/g vs. (23.8±2.9)μg/g; P<0.05]. Compared with control group, the levels of TNFα, IL-6, IL-1β, CXCL1, CXCL2, and VCAM-1 in sepsis group were increased. Compared with sepsis group, the above-mentioned molecular levels of pae group were significantly decreased [TNFα: (63.39±9.55)pg/ml vs. (126.54±19.17)pg/ml ;IL-6: (64.03±8.82)pg/ml vs. (85.60±9.52)pg/ml;IL-1β: (69.52±9.23)pg/ml vs. (130.45±15.10)pg/ml;CXCL1: (2 600.19±379.54)pg/ml vs. (4 903.89±533.42)pg/ml;CXCL2: (93.71±10.83)pg/ml vs. (127.24±13.92)pg/ml;VCAM-1: (112.22±13.49)pg/ml vs. (149.32±15.65)pg/ml, both P<0.05]. RT-qPCR results showed that the mRNA expressions of TNFα, IL-6, IL-1β, CXCL1, CXCL2 and VCAM-1 in the sepsis group were increased compared with the control group; Compared with sepsis group, the IL-6 mRNA (1.271±0.139 vs. 1.920±0.191, P<0.05), IL-1βmRNA (1.180±0.130 vs. 1.817±0.191, P<0.05), VCAM-1 mRNA (1.088±0.144 vs. 1.460±0.166, P<0.05) expression decreased significantly in the pae group. Compared with control group, the levels of P-p38MAPK and P-Src in sepsis group increased, and the level of VE-cadherin decreased. Compared with sepsis group, the levels of p38MAPK and P-p38MAPK in pae group were significantly decreased, and the level of VE-cadherin was increased (p38MAPK/β-actin: 1.125±0.078 vs. 1.520±0.164; P-p38MAPK protein: 1.639±0.133 vs. 2.112±0.222; both P<0.05). Conclusion: Paeoniflorin could improve the permeability of cardiac microvascular endothelium in sepsis rats and inhibit the secretion and expression of inflammation-related proteins and genes, which might be related to the inhibition of Src/VE-cadherin pathway by paeoniflorin.

Abstract
Objective: To investigate the effect of interleukin-33 (IL-33) on lipopolysaccharide (LPS)-induced permeability of rat cardiac microvascular endothelial cells (RCMECs). Methods: RCMECs were cultured in vitro to be divided into control group, LPS group, IL-33 group and LPS+IL-33 group. The effect of IL-33 on the proliferation of RCMECs was detected by cell counting reagent (CCK8). Fluorescein isothiocyanate (FITC)-dextran assay was used to evaluate the permeability of RCMECs. The expression of vascular endothelial calmodulin, ras homologous gene family (Rho) member A (RhoA) and phosphorylated Rho-associated coiled-coil-containing protein kinase (p-ROCK2) proteins were tested by western blot. High-throughput sequencing and gene ontology (GO) were performed for gene expression in LPS and LPS+IL-33 groups. Results: No significant effect of IL-33 at 10-50 ng/ml on the proliferation of RCMECs was observed (P>0.05). Compared with the control group, the permeability of RCMECs (permeability coefficient ratio 1.404±0.029 vs. 1.000±0.200, P<0.05) was significantly increased in LPS group and the expression of vascular endothelial calmodulin (relative gray value 0.429 5±0.012 9 vs. 0.594 9±0.014 2, P<0.05) was down-regulated, while the permeability of monolayers (permeability coefficient ratio, 0.948±0.013, P<0.01) was decreased in LPS+IL-33 group and the expression of vascular endothelial calmodulin (relative grayscale value 0.549 1±0.012 0, P<0.005) was up-regulated compared with the LPS group. High-throughput sequencing data revealed that the differential genes downregulated in the LPS and LPS+IL-33 groups were associated with cytoskeleton and Rho signaling pathway. Compared with the control group, RhoA (relative gray value 0.211 4±0.009 9 vs. 0.135 0±0.007 6, P<0.000 1) and p-ROCK (relative gray value 0.656 3±0.013 2 vs. 0.503 6±0.036 2, P<0.000 1) protein expression was upregulated in the LPS group. When compared with LPS group, RhoA (relative gray value 0.157 7±0.010 7, P=0.000 2), p-ROCK (relative gray value 0.427 7±0.003 8, P<0.000 1) protein expression was decreased in LPS+IL-33 group. Conclusion: IL-33 may improve LPS-induced hyperpermeability of RCMECs by inhibiting RhoA and p-ROCK protein expression in Rho/Rho-associated coiled-coil-containing protein kinase signaling pathway.

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 summarize the clinical characteristics and the features of electroencephalograph (EEG) of children with DEPDC5 gene variants related epilepsy. Methods: The clinical data, gene variation, EEG and head magnetic resonance image (MRI) of 20 epileptic children with DEPDC5 gene variants admitted to Department of Pediatrics, Peking University First Hospital from May 2017 to November 2020 were retrospectively analyzed. Results: Twenty patients with heterozygous DEPDC5 gene variants were enrolled, 8 of 20 patients were nonsense variants, 6 were missense variants, 3 were frame-shift variants, 2 were splicing variants, and 1 was large fragment deletion. Sixteen cases had hereditary variation and 4 had de novo variation. Fifteen of variations were novel. Nine were male, while 11 were female. Their latest follow-up age ranged from 10 months to 13 years and one month.The epilepsy onset age ranged from 3 hours to 11 years and 3 months, the median age was 10.5 months. Twelve (60%) patients had developmental delay. Nineteen patients had focal seizures, 7 had epileptic spasms, 1 had multiple seizure types including tonic, atypical absence, dystonic and myoclonic seizures. Epileptic form discharges were observed in 18 patients during the interictal phase, and 11 were focal discharges, 7 were multifocal discharges. Ten (50%) patients had abnormal brain MRI, including focal cortical dysplasia in 5 patients, undefined malformation of cortical development in 4 patients, hemimegalencephaly in 1 patient. Four patients were diagnosed as West syndrome and one patient was diagnosed as Lennox-Gastaut syndrome. Fourteen (70%) patients were diagnosed as drug-resistant epilepsy. Four patients became seizure-free by treatment with anti-epileptic drugs. Three children were treated with surgery, and 2 of them became seizure-free, 1 had more than 75% reduction in seizures. Conclusions: DEPDC5 gene variant epilepsy is inherited with incomplete penetrance and focal seizure is the major seizure type. However, epileptic spasms, generalized seizures can also be observed. Half of the patients brain malformations. Most of the patients are drug-resistant epilepsy. Patients with clear epileptogenic zones can be treated with surgery. Treatment-resistant patients are more likely to be complicated with developmental delay.

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 evaluate the safety and long-term clinical efficacy of percutaneous coronary intervention (PCI) in patients with in-stent chronic total occlusion (IS-CTO) lesions. Metheds: This is a retrospective analysis. Patients with IS-CTO who underwent PCI in Fuwai hospital from January 2010 to December 2013 were enrolled. A total of 212 patients who met the inclusion criteria were included in the IS-CTO group, 212 matched patients with primary CTO lesions were included in the de novo CTO group. The incidence of complications and the success rate of PCI were compared between the two groups. Successful PCI was defined as successfully implantation of stent(s) at target CTO lesions. The primary endpoint was defined as a composite event of cardiac death and myocardial infarction (MI). Secondary endpoints including PCI success, all-cause death, cardiac death, MI, target vessel related MI, revascularization, target vessel revascularization, heart failure for rehospitalization. The patients were followed up for 5 years after PCI. Results: A total of 424 cases were included. The mean age was (57.8±10.5) years, there were 364 males in this cohort. The left ventricular ejection fraction was significantly lower ((58.7±9.2)% vs. (61.0±7.7)%, P=0.01) and the SYNTAX scores was significantly higher (19.4±8.3 vs. 15.3±10.0, P<0.01) in IS-CTO group than that in de novo CTO group. The proportion of patients with target CTO lesions in left anterior descending artery was significantly higher (42.9% (50/212) vs. 23.6% (91/212), P<0.01) in IS-CTO group than that in de novo CTO group. The rate of successful PCI (71.7% (152/212) vs. 69.8% (148/212), P=0.70) and complication (40.6% (86/212) vs. 36.3% (77/212), P=0.37) was similar between the two groups. The incidence of primary endpoint at 5 years was significantly higher in IS-CTO group (10.8% (23/212) vs. 4.7% (10/212), P=0.02), which was driven by higher incidence of MI (9.0% (19/212) vs. 4.2% (9/212), P=0.05). There were a trend of higher secondary endpoints in IS-CTO group (all P>0.05). Conclusion: The safety and effectiveness of PCI are acceptable in patients with IS-CTO, but the risk of long-term cardiac death and MI is higher among patients with IS-CTO as compared to patients with primary CTO lesions.

Abstract
Objective: To investigate the characteristics of pulmonary function changes and its possible influencing factors in patients with pneumoconiosis. Methods: In December 2019, pneumoconiosis patients hospitalized in four departments of occupational diseases in Hunan Occupational Disease Prevention and Control Hospital from December 2015 to December 2016 were selected as subjects. Lung function including forced vital capacity (FVC) , FVC%, forced expiratory volume in one second (FEV1) , FEV1%, forced expiratory volume in one second / forced vital capacity (FEV1/FVC) , diffusion capacity of the lung foe carbon monoxide% (DLCO%) 、maximal expiratory rlow 75% (MEF75%) , maximal expiratory rlow 50% (MEF50%) and maximal expiratory rlow 25% (MEF25%) were tested, and collect their age, occupation history, smoking history and Chronic Obstructive Pulmonary Disease Self Rating Questionnaire (CAT) score. They were followed up after 3 years to analyze the 3-year decline rates of lung function indicators and their relationship with stage of pneumoconiosis, age, smoking index, baseline values of lung function and CAT score. Results: 265 cases were studied effectively. After 3 years, the values of 9 lung function indicators of pneumoconiosis patients were significantly lower than those of 3 years ago (P<0.05) . The decline rates of FEV1%, FEV1/FVC, MEF75%, MEF50% and MEF25% were positively correlated with the stage of pneumoconiosis (r=0.250, 0.290, 0.219, 0.280, 0.141, P<0.05) . The decline rates of FEV1% and MEF75% were positively correlated with smoking index (r=0.148, 0.152, P<0.05) . The decline rates of DLCO% and MEF25% were positively correlated with the baseline value of initial pulmonary function (r=0.276, 0.153, P<0.05) , while the decline rates of FEV1%, FEV1/FVC and MEF50% were negatively correlated with the baseline values of initial pulmonary function (r=-0.215, -0.146, -0.214, P<0.05) . The decline rates of FVC%, FEV1%, MEF75% and MEF50% were positively correlated with the changes of CAT scores (r=0.147, 0.208, 0.210, 0.196, P<0.05) . Logistic regression analysis showed that old age and high initial value of DLCO% were the risk factor for the decline of DLCO% (OR=1.105、1.078, P<0.05) .High smoking index was the risk factors for the decline of MEF75% (OR=1.016, P<0.05) . High stage and the increase of CAT score were the risk factors for the decline of MEF50% (OR=1.548, 1.162, P<0.05) . High initial value of MEF25% was the risk factor for the decline of MEF25% (OR=1.010, P<0.05) . Conclusion: The pulmonary function index of pneumoconiosis patients declined significantly in 3 years. The stage of pneumoconiosis, age, smoking index and degree of pulmonary function damage were related to the decline rate of pulmonary function.

Abstract
Objective: To investigate the genotype and phenotype of children with KCNA2 gene related developmental and epileptic encephalopathy (DEE). Methods: Clinical data including the manifestations and electroencephalogram of 8 children with KCNA2 variants treated in the Department of Pediatrics, Peking University First Hospital from March 2017 to June 2019 were collected and analyzed retrospectively. Results: Among the 8 epileptic patients with KCNA2 variants, 5 were males and 3 were females. The age of onset was from 1 day to 11 months. The age at last follow-up ranged from 4 months to 86 months. Two variants including c.1214C>T (loss-of-function) and c.1120A>G (gain-and loss-of-function) were identified. The variant of c.1214C>T was found in six patients (case 1-6). For these patients, the age of onset was from 5 to 11 months and they were characterized by multiple seizure types. All had focal seizures and had normal development before seizure onset with developmental regression after seizure onset. The first electroencephalogram showed epileptic discharges in Rolandic region in two, epileptic discharges in Rolandic region combined with generalized discharge in one, generalized discharge with posterior predominance in two (combined with or transferred to Rolandic region during the course) and epileptic discharges in posterior region combined with generalized discharge in one. And in 5 of them the Rolandic discharges developed into epileptic electrical status (ESES) during sleep. All the six patients were still treated with a combination of multiple antiepileptic drugs. Two of them had seizure controlled at 80 months and 68 months, respectively. The variant of c.1120A>G were identified in two of eight patients (case 7 and 8) and they had seizure onset on the 1st day after birth. Their epileptic seizures were frequent and difficult to control. They had remarkably developmental delay and microcephaly since birth. One case (case 8) had a wide forehead. They had frequent seizures up to the last follow-up. In case 7, the early electroencephalogram showed epileptic discharges in temporal region, and interictal electroencephalogram at 3 months of age showed multifocal discharge with posterior and temporal region predominance. In case 8, the early electroencephalogram was normal and electroencephalogram showed burst suppression at 2 months of age, and it developed epileptiform discharge in posterior region at 1 year of age. Conclusions: KCNA2 gene variants can lead to DEE with multiple seizures types. Among them, loss-of-function c.1214C>T is the most common, and these patients have seizure onset at infancy with Rolandic discharges tended to develop into to ESES pattern. The variant of c.1120A>G is a gain-of- and loss-of-function variant, patients with c.1120A>G have seizure onset in neonatal period, the phenotype overlaps with the former but is more severe.

Abstract
Objective: To investigate the electroclinical findings in epilepsy children with epileptic negative myoclonus (ENM) restricted to the lower limb as the first seizure type. Methods: Each retrieved electroencephalogram record performed between March 2011 and March 2018 at the Department of Pediatrics of Peking University First Hospital was searched with "midline" . There were 302 records of 175 patients with "benign" or "functional" midline spikes. A retrospective review of each patient's hospital record was performed. Thirteen patients had ENM restricted to the lower limb as the first seizure type. The clinical and electroencephalogram characteristics of them were analyzed. Results: Thirteen patients manifested ENM restricted to the lower limb as the first seizure type, diagnosed as benign childhood focal epilepsy with vertex spikes (BEVS). Six patients had ENM as the first and only seizure type during the short-time follow-up. Among them, there were 1 male and 5 females. The age at seizure onset was (2.5±0.7) years. One of them had electrical status epilepticus during sleep (ESES) identified on electroencephalogram at theage of 4 years and 8 months. The last follow-up age was (3.8±1.5) years. The remaining 7 patients developed nocturnal focal motor seizures. Among them, there were 4 males and 3 females. The age at seizure onset was (3.5±0.7) years. Two of them were diagnosed as BEVS evolving into benign childhood epilepsy with centrotemporal spikes (BECTS) and 5 were diagnosed as BEVS concurring with BECTS. The age at focal seizures was (4.1±0.6) years. The interval ranged from 1 month to 1 years. Six of 7 patients had electrical ESES with the age of (5.2±1.0) years. All had developmental regression, further diagnosed as atypical benign partial epilepsy (ABPE). The median age at last follow-up was 5.9 years. Five of 13 patients had repeated electroencephalogram records at our apartment, showing that epileptiform discharges in midline regions were significantly reduced either in frequency or amplitude with the improvement of ENM restricted to the lower limb and that independent epileptiform discharges in Rolandic regions from midline regions were noticed with the onset of nocturnal focal seizures. Conclusions: ENM restricted to the lower limb has a close association with vertex (midline) epileptiform discharges. ENM restricted to the lower limb as the first seizure type is a peculiar phenomenon of BEVS. Some patients could evolve into BECTS or overlap with BECTS, and further into ABPE. The age of seizure onset in BEVS with ENM restricted to the lower limb as the first symptom is a little earlier than in BECTS. Ignorance of the close association between midline spikes and ENM restricted to the lower limb may lead to misdiagnosis of these patients.

Abstract
Objective: To investigate the compliance of inhalation during stable phase of pneumoconiosis complicated with COPD and to explore the factors influencing compliance. Methods: The patients with pneumoconiosis complicated with COPD who were hospitalized in the four Department of occupational disease prevention and treatment in Hunan province from December 2016 to August 2017 were selected as the research subjects. The examination of Chest radiograph, HRCT and lung function was perfected, and CAT score and MRC score were carried out. The age, culture, smoking history, acute aggravation of 1 years, medical insurance and so on were collected, and follow-up was conducted after 6 months. Results: Of the 115 patients who had successfully followed up, 14 cases (12.17%) were persisted in medication, and 101 cases (87.83%) did not adhere to the medication. The smoking index median of the non adherence group was 30 (15, 40) , while that of the adherence group was 16 (6, 31) . The smoking index of the adherence group was lower than that of the non adherence group. The FEV1% in the unadhered group was 44.69+15.48, and the drug group was 37.12+16.98, the FEV(1)/FVC in the unadhered group was 52.43+9.19, and the drug group was 44.43+11.88, and the lung function of the drug group was worse than that of the unadhered group. The adherence rate of group COPD (group D) was higher than that of group A, B and C, and the difference between D group and B group was statistically significant. The adherence rate of pneumoconiosis stage Ⅲ was higher than that of pneumoconiosis stageⅡand pneumoconiosisⅠ. Conclusion: The compliance of long acting bronchodilator inhalation is low in stable phase of pneumoconiosis complicated with COPD. The poorer the lung function, the higher the compliance of inhalation. The compliance of pneumoconiosis patients with Medical insurance for industrial injury is higher than that of pneumoconiosis patients with New rural cooperative medical service.

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: To investigate the safety and influencing factors of ct-guided percutaneous lung biopsy in pneumoconiosis patients. Methods: The data of 63 patients with pneumoconiosis who underwent ct-guided percutaneous lung biopsy in our hospital were studied to analyze the incidence of complications and influencing factors of percutaneous lung biopsy. Results: 63 cases of pneumoconiosis patients received CT guided percutaneous lung biopsy. There were 29 cases of complications (46.03%) , including 20 pneumothorax (37.75%) , 12 bleeding (19.05%) , and 3 cases of liquid pneumothorax (4.76%) . The single factor chi square analysis showed that there were significant differences in age, depth of focus, puncture position and puncture times (P<0.05) , and there was significant difference between the occurrence of hemorrhage and age, type of focus, size of focus, and the location of puncture site (P<0.05) . The unconditional LogisticL multiple factor regression analysis showed that the depth of the lesion was an independent risk factor for concurrency pneumothorax, and the size of the lesion was an independent risk factor for bleeding. Conclusion: Complications of CT-guided percutaneous pulmonary biopsy are mainly pneumothorax and hemorrhage. Age, focus type, focus size, focus depth, puncture site, and puncture times are all the factors of complications.

Abstract
Objective: To characterize the clinical epidemiological features of primary lung cancer patients based on massive clinical data. Methods: The demographic and histological information of 8 081 primary lung cancer patients who were initially identified from 1 January 2012 to 31 December 2013 in 16 hospitals from 6 provinces were retrospectively analyzed to determine the characteristics of different histological subtypes among different gender, age-group and birth cohort. Results: Among the 8 081 lung cancer patients, 5 422 (67.10%) were male and 2 659 (32.90%) were female, the average age was (60.96±10.14) years. The most common histological subtypes of lung cancer successively were adenocarcinoma (ADC), squamous cell carcinoma (SCC), small cell carcinoma and large cell carcinoma, and the proportions of these subtypes were 53.13%, 24.51%, 14.59% and 0.66%, respectively, which collectively accounted for 92.89%. The current highest smoking rate was observed in SCC patients, which was 62.45%, while lowest in ADC, which was 29.68%. The incidence of lung cancer in male was significantly higher that that of female, with a sex ratio of 2.04∶1. The highest sex ratio was observed in SCC, which was 9.14∶1, while lowest in ADC, which was 1.14∶1. The distribution of histological subtypes in male lung cancer patients was consistent with the general situation.While among the female lung cancer patients, the proportion of ADC was the highest (75.42%), followed by SCC (10.08%), squamous cell carcinoma (7.34%) and large cell carcinoma (0.39%). Analyzed by the birth cohort, the proportion of ADC gradually increased with the age, while the reduced tendency was observed in SCC (P<0.000 1). Conclusion: Adenocarcinoma is the most important histological subtype of lung cancer, and the distribution characteristics of histological subtypes of lung cancer differs among genders, age and birth cohort.

Abstract
OBJECTIVES To analyze the causes of perinatal death and related factors from the perspective of forensic medicine, and to provide references for reducing perinatal mortality and guidance for forensic identification. METHODS A retrospective analysis was performed on 102 cases of perinatal autopsy with clinical data from the Department of Forensic Medicine of Chongqing Medical University in 2004-2016. RESULTS Of the 102 cases of perinatal deaths, 66 (64.71%) were neonatal deaths, 24 (23.53%) were stillborn foetuses, and 12 (11.76%) were stillbirths. Among the 66 neonatal death cases, 39 (59.09%) died within 1 d, 19 (28.79%) died within 1-3 d, and 8 (12.12%) died within >3-7 d of birth. The top 3 causes of neonatal death were pulmonary diseases, congenital malformation, umbilical cord and placental abnormalities. The causes of stillborn foetus and stillbirth were mainly umbilical cord and placental abnormalities, and intrauterine asphyxia. CONCLUSIONS Pulmonary diseases, umbilical cord and placental abnormalities, and congenital malformations are the main causes of perinatal death. In order to reduce the perinatal mortality, pre-pregnancy examination and prenatal care should be strengthened, and the knowledge of pregnancy care should be popularized.

Objective: To analyze the trends of cancer incidence and age changes in China with using cancer registration data, and to provide evidence for the development of cancer prevention and control. Methods: Twenty-two cancer registries with continuous (2000-2014) data were selected. The incidence of different sex and regional population, the standardized incidence rate by Chinese population, the average annual change percentage (AAPC) and annual change percentage(APC) were calculated. Age-period-cohort model were used to analyze the changes of cancer incidence, age-adjusted mean ages. The age-standardized proportion of 2000 and 2014 with were compared. Results: The cancer incidence in China increased by 3.9% (95%CI: 3.7%-4.1%) from 2000 to 2014 in APC, and the age-standardized incidence rate increased by 1.2% (95%CI: 1.0%-1.4%) in AAPC. The age-specific incidence showed that each age groups increased significantly in female, ranged between 0.9% to 6.0%. The APC in male aged from 60 years old showed decline trend, the APC in 60-69, 70-79, ≥80 years old were -0.2, -0.3, -0.3, while in the population aged 0-29, 30-39 years old increased dramatically, APC were 3.5, 2.0. Female under 60 also increased, and APC in 0-29, 30-39, 40-49, 0-59 years old were 5.7, 6.0, 3.4, 2.9, respectively. The mean age of patients diagnosed with cancer were increased during the past 15 years, with about 0.11 years per year increased. However, the mean age of the patients diagnosed with cancer showed decreased trend by 0.13 years after age structure adjusted. Conclusion: The trend of mean age for cancer incidence in China were getting younger than before, and the trend in women is more obviously than in man.

Abstract
Objective: To estimate the incidence trend and change in the age distribution of female breast cancer in cancer registry areas in China from 2000 to 2014. Methods: 22 cancer registries in China with continuous monitoring data from 2000 to 2014 were selected. All datasets were checked and evaluated based on data quality control criteria and were included in the analysis. The cancer registries covered 675 954 193 person-years, including 342 010 930 person-years of male and 333 943 263 person-years of female. Female breast cancer cases (International Classification of Diseases-10(th) Revision: C50) were extracted. Crude incidence rate (CR), age-standardized incidence rate by Chinese standard population(ASIRC), annual percent change (APC), crude and adjusted mean age at onset were calculated. Incidence rates stratified by regions and age groups were calculated. Results: Female breast cancer incidence rate significantly increased from 31.90/100 000 in 2000 to 63.30/100 000 in 2014. Incidence rate increased rapidly from 2000 to 2008 (CR: APC=6.5%, 95%CI: 5.3%-7.8%; ASIRC: APC=4.6%, 95%CI: 3.6%-5.7%). Its increment slowed down from 2008-2014 (CR: APC=3.2%, 95%CI: 1.4%-5.1%; ASIRC: APC=1.4%, 95%CI:-0.1%-2.9%). The crude mean age at onset increased from 54.4 in 2000 to 57.0 in 2014. Adjusted mean age at onset remained around 54.3 in 2014. Crude mean age at onset increased significantly over time in all registry areas (β=0.192, P<0.001), urban (β=0.205, P<0.001) and rural (β=0.092, P=0.014) areas, while adjusted mean age at onset remained stable in all registry areas (β=0.009, P=0.289), urban (β=0.017, P=0.139) and rural (β=-0.054, P=0.109) areas. Conclusion: Female breast cancer incidence rate in China increased from 2000 to 2014. Aging of the population resulted in a significant increase in crude mean age at onset. After age adjustment, no significant changes in age distribution were found.

Abstract
Objective: To estimate lung cancer incidence and mortality in China using population-based cancer registry data in 2014 collected by National Central Cancer Registry of China (NCCRC). Methods: 449 cancer registries submitted cancer registry data in 2014. All datasets were evaluated and 339 registries' data which met the quality control criteria of NCCRC were analyzed. Numbers of new lung cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by areas, sexes and age groups. The standard population of Chinese census in 2000 and world Segi' s population were applied to calculate age-standardized incidence and mortality rates in China and worldwide, respectively. Results: A total of 781, 500 new lung cancer cases were diagnosed in 2014. The crude incidence rate was 57.13 per 100 000 and the age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 36.71 per 100 000 and 36.63 per 100 000, respectively. The cumulative incidence rate (0-74 years old) was 4.50%. Lung cancer was the most common cancer in male (ASIRW: 50.04 per 100 000) and the second most common cancer in female (ASIRW: 23.63 per 100 000). The incidence rates were slightly similar in urban areas and in rural areas (ASIRW: 36.64 per 100 000 vs 36.56 per 100 000). A total of 626 400 lung cancer deaths were reported. The crude mortality rate was 45.80 per 100 000 and the age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 28.49 per 100 000 and 28.31 per 100 000, respectively. The cumulative mortality rate (0-74 years old) was 3.32%. Lung cancer was the most common cause of cancer deaths both in male (ASMRW: 40.21 per 100 000) and female (ASMRW: 16.88 per 100 000). The mortality rate was slightly higher in rural areas than in urban areas (ASMRW: 28.63 per 100 000 vs 28.04 per 100 000). Both lung cancer incidence and mortality rates increased with age, and the peak age was 80-84 years group. Conclusions: The disease burden of lung cancer is heavy in China. Efficient national health policies and prevention and control strategies against lung cancer should be promoted.

Abstract
Objective: To estimate the incidence and mortality of stomach cancer in China based on the cancer registration data in 2013, collected by the National Central Cancer Registry (NCCR). Methods: There were 347 cancer registries that submitted stomach cancer incidence and deaths occurred in 2013 to NCCR. After evaluating the data quality, 255 registries' data were accepted for analysis and stratified by areas (urban/rural), sex, and age group. Combined with data on national population in 2013, the nationwide incidence and mortality of stomach cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 255 cancer registries covered a total of 226 494 490 populations (111 595 772 in urban and 114 898 718 in rural areas). The percentage of cases morphologically verified and death certificate-only cases were 76.27% and 1.98%, respectively, and the mortality to incidence rate ratio was 0.72. It is estimated that there were 427 000 new cases for stomach cancer nationwide, with a crude incidence rate of 31.38 per 100 000 (42.85 per 100 000 in males, 19.33 per 100 000 in females). The age-standardized incidence rates by Chinese standard population (ASR China) and by world standard population (ASR world) were 21.40 per 100 000 and 21.32 per 100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 2.66%. The crude and ASR China incidence rates of stomach cancer in urban areas were 27.80 per 100 000 and 18.48 per 100 000, respectively, whereas those were 35.54 per 100 000 and 24.93 per 100 000 in rural areas. It is estimated that there were 301 000 deaths for stomach cancer nationwide, with a crude mortality rate of 22.13 per 100 000 (29.85 per 100 000 in males, 14.03 per 100 000 in females). The ASR China and ASR world mortality rates were 14.68 per 100 000 and 14.54 per 100 000, respectively, with a cumulative mortality rate (0-74 years old) of 1.70%. The crude and ASR China mortality rates were 18.94 per 100 000 and 12.20 per 100 000 in urban areas, respectively, whereas those were 25.84 per 100 000 and 17.67 per 100 000 in rural areas. Conclusions: There is still a heavy burden of stomach cancer in China. The burden and patterns of stomach cancer shows different gender and urban-rural differences. Prevention and control strategies should be implemented referring to local status.

Abstract
Objective: To investigate the change in peripheral nervous conduction velocity in patients with occupational chronic mercury poisoning and related influencing factors. Methods: From February 2011 to December 2014, urinary mercury examination and neural electromyography were performed for 104 patients with occupational chronic mercury poisoning. The data on age, type of work, working years of mercury exposure, and past medical history were collected, and peripheral nervous conduction velocity and its correlation with age, working years of mercury exposure, and urinary mercury concentration were analyzed. Results: All the 104 patients with occupational chronic mercury poisoning had a mean of 45.37±9.82 years, median (P(25), P(75)) working years of 7 (3, 11) , and a median (P(25), P(75)) urinary mercury concentration of 88.50 (56.25, 163.03) μg/g Cr. The major clinical manifestations of peripheral nerve injuries were numbness of extremities (20.2%) , hypopselaphesia/hypalgesia or hyperpselaphesia/hyperalgesia (9.6%) , and bone/muscle pain in the extremities (6.7%) . Neural electromyography showed an increase in denervation potential (fibrillation potential or positive sharp wave) and a detection rate of abnormal peripheral nervous conduction velocity as high as 65.4%. The patients with an older age and more working years had a higher incidence rate of abnormal sensory conduction velocity of the ulnar nerve. There were significant reductions in motor and sensory conduction velocities of the median nerve, motor and sensory conduction velocities of the ulnar nerve, motor conduction velocity of the common peroneal nerve, and the sensory conduction velocity of the superficial peroneal nerve (P<0.05) , with the increase in urinary mercury concentration. Conclusion: Patients with occupational mercury poisoning have a high rate of abnormal neural electromyographic findings, which can be used as an important method for early identification of chronic peripheral nerve injuries induced by mercury poisoning. The degree of peripheral nerve injuries increases with the increasing time of mercury exposure and urinary mercury concentration.

Abstract
Objective: To summarize the clinical features of TBC1D24 gene mutations associated with epilepsy. Methods: All the patients with TBC1D24 gene compound heterozygous mutations were retrospectively collected at the Pediatric Department of Peking University First Hospital from March 2015 to July 2017, and the features of clinical manifestations, electroencephalogram, and neuroimaging were analyzed. Results: Eighteen cases with TBC1D24 gene compound heterozygous mutations were included. The age of seizure onset was 1 day to 8 months, and the median age was 90 days. Seizure types included generalized tonic-clonic seizures (GTCS) in 3 cases, focal seizures in 18 cases, myoclonus in 18 cases, and 17 cases had focal myoclonus and myoclonus status. The focal myoclonus involving one or multiple muscle groups, sometimes migrating and alternating, lasting up to minutes to several days, and could be terminated by sleep or sedation drugs. In 11 cases, myoclonus was exacerbated by fever or infections, and 2 cases developed into myoclonic status during infection, in a severe case with the loss of consciousness. The magnetic resonance imaging (MRI) of seven patients was abnormal, including cerebral atrophy or cerebellar atrophy with abnormal signals. Segment myoclonus was captured in 10 patients, but without correlated epileptiform discharges. There were ten cases had varying degrees of developmental delay, 7 were normal, and one patient died of status epilepticus at the age of 4 months. Three cases had hearing disorders. In the 18 patients, the clinical phenotype of 4 cases consisted of epilepsy of infancy with migrating focal seizures, 2 with progressive myoclonus epilepsies, 1 with Dravet syndrome, 1 with DOORS syndrome, and 3 with unclassified epileptic encephalopathy. Conclusions: The clinical feature of TBC1D24 gene mutation related epilepsy was focal myoclonus, and tended to develop into myoclonic status epilepticus, and could be aggravated by infections, and terminated by sleep or sedation drugs. Mental retardation involved or not, neuroimaging could present with cerebral atrophy or cerebellar atrophy with abnormal signals.

Abstract
Objective: To investigate the spectrum of mutations in families with benign familial neonatal-infantile epilepsy (BFNIE) . Methods: Clinical data and peripheral blood DNA samples of all BFNIE probands and their family members were collected from Peking University First Hospital between December 2012 and April 2016. Clinical phenotypes of affected members were analyzed. Genomic DNA was extracted from peripheral blood samples with standard protoco1. Mutations in PRRT2 were screened using Sanger sequencing. For families that PRRT2 mutations were not detected by Sanger sequencing, candidate gene mutations were further screened by next-generation sequencing for epilepsy. Results: A total of 7 families were collected. Of the 30 affected members, 15 were male and 15 were female. The age of epilepsy onset was from 2 days to 6 months. Genetic testing led to the identification of gene mutations in all families. One family had the PRRT2 hotspot mutation (c.649dupC). Three families had missense SCN2A mutations (c.2674G>A/p.V892I, c.2872A>G/p.M958V, and c.2627A>G/p.N876S) . Both c.2872A>G/p.M958V and c.2627A>G/p.N876S were novel SCN2A mutations. Three families had KCNQ2 mutations. Two of them had missense mutations (c.958G>A/p.V320I and c.998G>A/p.R333Q) . The KCNQ2 mutation c.958G>A/p.V320I was novel. One family had a gene deletion of KCNQ2, which also extended to the adjacent gene, CHRNA4; and the deletion involved all the exons of KCNQ2 and CHRNA4. Conclusions: Mutations in KCNQ2, SCN2A, and PRRT2 are genetic causes of BFNIE in Chinese families. The detection rate for gene mutations is high in BFNIE families. KCNQ2 and SCN2A mutations are common in BFNIE families. SCN2A mutations (c.2872A>G/p.M958V and c.2627A>G/p.N876S) and KCNQ2 mutation (c.958G>A/p.V320I) are novel mutations.

Abstract
OBJECTIVE To investigate the clinical significance of high-frequency oscillations (HFOs) on scalp electroencephalography (EEG) in patients with epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS). METHODS Twenty-one CSWS patients treated for epilepsy from January 2006 to December 2016 in Pediatric Department of Peking University First Hospital were enrolled into the study. Selected clinical variables including gender, age parameters, seizure frequencies and antiepileptic drugs were compared between (a). HFO-positive group and HFO-negative group before methylprednisolone treatment and (b). excellent seizure outcome group and not-excellent seizure outcome group after methylprednisolone treatment. Interictal HFOs and spikes in pre- and post-methylprednisolone scalp EEG were measured and analyzed. RESULTS Before methylprednisolone treatment, there were 12 of 21 (57%) CSWS patients had HFOs, with a mean value 43.17 per 60 s per patient. The 12 patients with HFOs tended to have more frequent epileptic negative myoclonus/atonic/myoclonus/atypical absences than those without HFOs in a month before methylprednisolone treatment. A total of 518 HFOs and 22 592 spikes were found in the pre-methylprednisolone EEG data of 21 patients, and 441 HFOs (86%) were associated with spikes. The highest amplitudes of HFOs were significantly positively correlated with that of spikes (r=0.279, P<0.001). Rates reduced by methylprednisolone treatment were statistically significant for both HFOs (P=0.002) and spikes (P=0.006). The percentage of reduction was 91% (473/518) and 39% (8 905/22 592) for spikes and HFOs, respectively. The percentage of spike and HFOs changes was respectively 100% decrease and 47% decrease in the excellent seizure outcome group, and they were 79% decrease and 18% increase in the not-excellent seizure outcome group. CONCLUSION Prevalence of HFOs might reflect some aspect of epileptic activity. HFOs were more sensitive to methylprednisolone treatment than spikes and had a good correlation with the prognosis of seizures, and HFOs could be applied to assess epilepsy severity and antiepileptic therapy.

Abstract
Objective: To estimate the incidence and mortality of female breast cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for breast cancer prevention and control in China. Methods: There were 449 cancer registries submitting female breast cancer incidence and deaths data occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of female breast cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas) in 2014. The morphology verified cases (MV%) accounted for 87.42% and 0.59% of incident cases were identified through death certifications only (DCO%), with mortality to incidence ratio of 0.24. The estimates of new breast cancer cases were about 278 900 in China in 2014, accounting for 16.51% of all new cases in female. The crude incidence rate, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of breast cancer were 41.82/100 000, 30.69/100 000, and 28.77/100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 3.12%. The crude incidence rates and ASRIC in urban areas were 49.94 per 100 000 and 34.85 per 100 000, respectively, whereas those were 31.72 per 100 000 and 24.89 per 100 000 in rural areas. The estimates of breast cancer deaths were about 66 000 in China in 2014, accounting for 7.82% of all the cancer-related deaths in female. The crude mortality rate, age-standardized rate of mortality by Chinese standard population(ASRMC) and age-standardized rate of mortality by world standard population (ASRMW) of breast cancer were 9.90/100 000, 6.53/100 000, and 6.35/100 000, respectively, with a cumulative mortality rate of 0.69%. The crude mortality rates and ASRMC in urban areas were 11.48 per 100 000 and 7.04 per 100 000, respectively, whereas those were 7.93 per 100 000 and 5.79 per 100 000 in rural areas. The incidence and mortality rates of breast cancer were higher in areas than those in rural areas. The age-specific incidence rates of breast cancer increased greatly after 20 years old and peaked at the age group of 55-60. The age-specific mortality rates increased rapidly with age, particularly after 25 years old. They remained at a relative stable level from 55 to 65 years of age, and then increased dramatically and peaked in the age group of 85 and above. Conclusions: Breast cancer is still one of the most common malignant tumor threatening to famale health in China. The disease is more prevalent in urban areas at the age group of 55-60. Comprehensive prevention and control strategies referring to local status and age groups should be carried out to reduce the burden of breast cancer.

Abstract
To explore the clinical and genetic characteristics of Williams-Beuren syndrome (WBS) and to raise awareness of the disease. The characteristics of clinical manifestations, personal history, cardiac ultrasound, brain magnetic resonance imaging (MRI), electroencephalogram (EEG) and chromosome detection results of two cases with WBS were analyzed. The two patients were both male and the age was 11 months and 1 day, and 9 months and 9 days, respectively. They both suffered from cardiovascular malformation: case one presented supravalvular aortic stenosis, and case two showed atrial septal defect and patent ductus arteriosus. Both of the cases were exhibited characteristic facial features of WBS, including full orbital, spherical nose, flat nasal bridge, long philtrum and thick lips. For the mental development, case one displayed moderate to severe developmental retardation, and case two showed severe developmental retardation. In addition, case one presented bilateral indirect inguinal hernia and hydrocele, and case two manifested feeding difficulties, buried penis and infantile spasms. Personal history: case one's mother had tocolytic therapy during pregnancy period, and case one was born at full-term by cesarean section due to amniotic fluid pollution. Supplementary examination: brain MRI of the two cases were no significant abnormalities; the EEG of case two showed hypsarrhythmia, and the epileptic spasms were recorded. Chromosome detection results: case one was identified as 7q11.23 deletion including the fragment deletion mutation of elastin (ELN) gene by multiplex ligation dependent probe amplification method, and case two was found with 7q11.21q11.23 deletion by high resolution G-band method. The two cases with WBS both had cardiovascular malformations, special facial features, mental retardation and connective tissue or urinary system abnormality. The supravalvular aortic stenosis of case one may be associated with the deletion of ELN gene, and the occurrence of epilepsy of case two may be related to the q11.21 deletion beyond the 7q11.23 region.

Abstract
OBJECTIVE To analyze the clinical and genetic characteristics of patients with pyridoxine dependent epilepsy (PDE), and build a method to detect and analyze the concentration of urinary pipecolic acid in PDE patients receiving pyridoxine treatment. METHOD Twelve patients (8 were male, 4 were female) were diagnosed as PDE in Peking University First Hospital between April 2012 and September 2015. The clinical manifestations, diagnosis and treatment process, video-electroencephalogram, magnetic resonance imaging were retrospectively analyzed. ALDH7A1 gene was detected using Sanger sequencing or targeted next-generation sequencing. The concentration of urinary pipecolic acid in PDE patients was detected with gas chromatography-mass spectrometry (GC-MS), as well as in some non-PDE children served as normal control. All controls, 58 cases totally, were neonates born in our hospital or children came to our hospital for reasons such as syncope (without disturbing pipecolic acid metabolism) from November 2015 to January 2016. Of them, 25 were ≤6 months old(14 were male, 11 were female), 33 were >6 months old(14 were male, 19 were female). The Student's t-test or Mann-Whitney U test was used for comparing the pipecolic acid between the two groups. Correlation analysis was conducted using Pearson or Spearman test. RESULT Of the 12 patients, seven of them were abnormal at birth. The age of epilepsy onset was from 5 h to 5 months, within 10 d in 8 patients. After a diagnostic delay time of 15 d to 20 months, seizures in all patients were controlled by pyridoxine monotherapy, at a dose of higher than 10.0 mg/(kg·d) in 10 patients, and 8.5 and 2.5 mg/(kg·d) in the other 2 patients respectively. The range of maintenance dose was 2.5-20.0 mg/(kg·d) during the follow up. Interictal electroencephalogram showed nonspecific abnormality in 10, normal in 2. Brain magnetic resonance imaging showed nonspecific abnormality in 7, normal in 5. ALDH7A1 mutations were found in all patients, including 15 different mutation sites, four of which were never reported before. Splicing mutation IVS11+ 1G>A was carried in 6 patients, with a frequency of 25% (6/24). At the last follow-up, eleven patients were in various degree of psychomotor development delay, including the 4 patients with severe delay in whom birth abnormalities presented, and no significant delay was found in one patient. The concentration of urinary pipecolic acid in control: age ≤6 months, median 8.47 (0.46-35.33) mmol/mol creatinine; age >6 months, median 0.66 (0.12-3.52) mmol/mol creatinine. The concentration of urinary pipecolic acid was different between two groups of control (Z=-5.464, P<0.01). Twelve patients were all older than 6 months when they were tested, and the concentration was only mildly elevated in one patient, the range of 12 patients was 0.14-4.08 mmol/mol creatinine. The concentration was not significantly different between the control with age >6 months and our PDE patients (Z=-0.655, P>0.05). There were no significant correlations between the concentration of urinary pipecolic acid and the initial dose or maintenance dose at last follow-up of pyridoxine (r=0.418 and 0.166, P=0.176 and 0.607). CONCLUSION Seizures start in early infancy in most PDE patients. The splicing mutation IVS11+ 1G>A is supposed to be a probable"hotspot"mutation with a high frequency in Chinese PDE patients. Most patients have different levels of psychomotor development delay after seizures are controlled, and the patients with birth abnormalities may have worse outcomes. No relationships between the diagnostic delay time and the development outcome are found. The concentration of urinary pipecolic acid can return to normal during treatment with pyridoxine.

Abstract
Objective: To summarize the clinical features and gene mutations of epilepsy of infancy with migrating focal seizures (EIMFS). Method: Clinical features and electroencephalograms(EEG)of 9 patients with EIMFS of Peking University First Hospital from May 2015 to January 2016 were analyzed. Candidate gene mutations were screened by next generation sequencing. Result: Among the 9 patients, 3 were males and 6 were females. Two patients had family history. Seizure onset age was 2 days to 3 months after birth (median age 35 days). Migrating focal seizure was presented. Seizures manifested as eyes and(or)head deviation, involuntary blinking, swallowing, trembling or stiffness of limbs, hand clenching, flushing and cyanosis of lips, etc. Four patients had a history of status epilepticus. All 9 patients had psychomotor delay. EEG of all patients presented relatively slow background; during interictal phase, there were multi-focal epileptic discharges, which dominated one hemisphere or brain region; seizures were recorded in all 9 cases, which manifested eyes or(and)head deviation, stiffening or trembling of limbs, lip smacking, etc. Corresponding EEG showed low-medium-amplitude fast waves that originated from some brain regions and migrated to other regions. Cranial magnetic resonance imaging (MRI) was abnormal in 4 cases, which predominantly showed white matter dysplasia and enlargement of subarachnoid spaces. Two cases carried heterozygous missense mutations of SCN1A gene, while 3 cases carried heterozygous missense mutations of KCNT1 gene, all of which were de novo. One case carried compound heterozygous mutation of TBC1D24 gene(p.Gln207*, p. Ala289Va). Gene mutation was not found in 3 cases. All patients used multiple antiepileptic drugs (AED) and their seizures were not controlled. Follow-up ranged from 2 months to 5 years and 8 months, during which 4 were found dead. Two were lost to follow-up. Conclusion: EIMFS is clinically characterized by early onset, which is usually within 3 months after birth, migrating focal seizures, psychomotor delay, bad response to AED and high death rate. The interictal EEG showed multi-focal discharges, while ictal EEG shows migrating multifocal discharges. Genetic analysis can assist in diagnosis and genetic counseling.

Abstract
Objective: To investigate the clinical and neuroimaging characteristics of acute encephalopathy (AE) after status epilepticus (SE) of patients with Dravet syndrome (DS). Method: The clinical data of DS patients who had AE (coma ≥24 h) after SE were retrospectively collected from February 2005 to August 2016 in Peking University First Hospital and SCN1A gene tests were performed.The clinical and neuroimaging features were summarized. Result: Twenty-two patients (9 males and 13 females) with AE were collected among 412 DS patients during follow-up.Of which 18 patients had SCN1A gene mutations while the remaining 4 patients had no SCN1A gene mutations.The onset age of AE was between 6 months and 10 years.The duration of SE varied between 40 minutes and 9 hours.Prior to the onset of SE, twenty-one patients had high fever, and one patient had normal temperature.Coma lasted from 2 days to 20 days.Nine patients died after the AE, and 13 patients survived with massive neurological regression.From AE to the last visit, the median time of follow-up was 2 years and 3 months (from 7 months to 4 years and 4 months). Nine of 13 survivors had varied improvement in motor, language and cognition, while the remaining 4 patients had no significant improvement.After AE, there were 6 patients with seizure-free, 4 patients with reduced seizures, and 3 patients with no change in seizure frequency, moreover, spasm occurred in 2 patients.Six patients had brain magnetic resonance imaging (MRI) in acute phase and showed bilateral (2 patients) or unilateral (4 patients) hemisphere edema, accompanied by subcortical white matter hyperintense signal in T1 and T2 weighted images in two patients.The neuroimaging of 13 survivors demonstrated diverse cortical atrophy during recovery phase, among which 4 patients showed cerebellar atrophy, one patient had right pontine atrophy, 4 patients accompanied by signal abnormalities in subcortical and periventricular white matter, 2 patients showed right hippocampal sclerosis, and one patient showed signal abnormalities in bilateral basal ganglia. Conclusion: SE is more prone to occur in Dravet patients who have high fever.It may result in AE or even death in severe cases.Survivors will leave severe neurological sequelae.The neuroimaging shows brain edema in acute phase.In recovery phase the neuroimaging shows diverse brain atrophy, moreover, a few patients may be associated with cerebellar or pontine atrophy, hippocampal sclerosis or abnormal signals in white matter or basal ganglia.

Abstract
OBJECTIVE To explore the effect of ulinastatin on prevention of acute respiratory distress syndrome (ARDS). METHODS A prospective multicentral cohort study was conducted. The patients from three intensive care units (ICUs) of grade A tertiary hospitals in Beijing and a ICU of grade A tertiary hospitals in Cangzhou from January 2012 to December 2014, included 77 ARDS at-risk patients with ulinastatin treatment and 108 ARDS at-risk patients without ulinastatin treatment (control) were eligible. Both groups received normal treatment; additionally, the intervention group received 600 000 units of ulinastatin via intravenous infusion for 5 days. The control group received the same amount of saline via intravenous infusion for 5 days. Venous blood human neutrophil elastase (HNE) and peptidase inhibitor 3 (PI3) levels were measured on days 1, 3, and 7, respectively. Other outcomes included acute physiology and chronic health evaluation scoring II (APACHE II), body temperature, respiratory rate, heart rate, mean arterial pressure, white blood cell counts, PaO2/FiO2, ARDS incident, mechanical ventilation time, ICU treatment and hospitalization duration, 28 days mortality. RESULTS The PI3 levels showed no statistical difference on day 1, but significant differences on day 3 and day 7 between the two groups (P<0.01). HNE/PI3 ratio showed no statistical difference on day 1, but significant differences on day 3 and day 7 (P<0.05). PaO2/FiO2 was significantly higher in ulinastatin group on day 3 and day 7 (P<0.05). The incident rate for ulinastatin group was 15.58%, lower than that for the control group (33.33%), and the difference was statistically significant (P<0.05). The mechanical ventilation time and ICU treatment time in ulinastatin group was shorter than that in the control group, and the difference was statistically significant (P<0.05). There were no significant effects in other factors. CONCLUSION Increased dose of ulinastatin can recover the balance of HNE and its antagonist, lower the HNE's damage to lungs, and further reduce the ARDS incident rate.

Abstract
OBJECTIVE To explore the genotype and phenotype of female Dravet syndrome (DS) patients with PCDH19 mutations. METHOD Clinical data of all DS patients seen at Pediatric Department of Peking University First Hospital from February 2005 to May 2015 were prospectively collected. Genomic DNAs were extracted from the patients and their family members. Female DS patients without SCN1A mutation were enrolled. PCR and Sanger sequencing were performed to identify PCDH19 mutations. Clinical data of DS patients with PCDH19 mutations were summarized. RESULT Five different heterozygous PCDH19 mutations were identified in six unrelated patients of 75 SCN1A-negative female DS patients (8%), among whom five patients had de novo mutations and one patient's mutation was inherited from her affected mother. Three missense mutations and two insertion mutations were all located in exon 1. Mean age of onset of the six patients with PCDH19 mutations was 6.8 months (range 5-9 months). Onset of seizures were triggered by fever in four patients, after vaccination in one and without fever in one. Generalized tonic clonic seizure (GTCS) was the first seizure type in four patients and focal seizure with secondary generalized tonic clonic seizures in the remaining two. During the course, all patients presented multiple seizure types including generalized tonic clonic seizures and focal seizures in all six patients, myoclonic seizures in three, absence seizures and atonic seizures in one respectively. In all patients, seizures manifested fever-sensitive and in clusters. Seizures were always in brief duration, in most less than 5 minutes, except one experienced twice status epilepticus triggered by fever. Six patients had development delay after the seizure onset, two with autism spectrum disorder, three with ataxia. CONCLUSION PCDH19 is another important gene of DS after SCN1A, mutations mainly occurred de novo. PCDH19 gene mutation should be routinely screened in female DS patients without SCN1A mutation. The clinical features of female DS patients with PCDH19 mutations include that the main seizures types are generalized tonic clonic seizures and focal seizures, seizures occurr in clusters and fever-sensitive, short seizure duration, rare status epilepticus, common development delay and some may manifest autism spectrum disorders.

Abstract
OBJECTIVE The aim of this study was to investigate the correlation of twisting motion phase and infantile spasms in high risk infants. MATERIALS AND METHODS One hundred seventy-eight high-risk newborns experiencing follow-up in the rehabilitation phase were selected and full-body motion quality assessment was performed in the twisting motion phase. The occurrence of infants with infantile spasms after 12 months (corrected age) was statistically analyzed. RESULTS No clear correlation was found between monotonous movement twisting motion phase and infantile spasms, and spasm synchronized movement had no definite prediction for infantile spasms. The incidence of infant spasm with movement form having spastic synchronized characteristics had significant difference compared with monotonous systemic movement (p < 0.01). The sensitivity of predictive rate for spasm-synchronous movement of infantile spasms was 90.9%, the specificity was 96.8%, the positive predictive value was 80%, and the negative predictive value was 98.7%. CONCLUSIONS Spasm synchronized movement had some predictive value for infantile spasms in twisting motion stage. The newborns with this kind of movement form should be checked by regularly ambulatory EEG.

Abstract
The study aimed to investigate the bio-distribution and radio-immuno-imaging features of [(131)I]-herceptin in nude mice with BT-474 breast carcinoma. [(131)I]-Herceptin was administrated by tail intravenous injection to the nude mice with BT-474 breast carcinoma. Radiocounting was performed at 4, 12, 24, 48, and 96 h after administration. The activity ratio in the tumor tissue and non-tumor tissue (T/NT) and the radiocounting percentage per gram tissue to the injected dose (%ID/g) were calculated. The nude mice with BT-474 breast carcinoma were also visualized continuously by single photon emission computed tomography at 2, 4, 8, 12, 24, 48, and 96 h after the injection of [(131)I]-herceptin. Nude mice with MDA-MB-231 used as the control group were subjected to the same analyses. Clear tumor images were obtained after the injection of [(131)I]-herceptin in nude mice with BT-474 breast carcinoma. The images were the clearest at 24 h after the injection and remained clear even at 96 h. The T/NT ratio and %ID/g in the tumor tissues of nude mice with BT-474 were both significantly higher than those of the control group (P < 0.01). [(131)I]-Herceptin displays tumors clearly in the nude mice with BT-474 and accumulates well in the tumor tissues.

Abstract
The objective of this study was to explore the feasibility and methods of screening the residual normal ovarian tissue adjacent to orthotopic ovarian carcinomas in nude mice. Human epithelial ovarian cancer cells (OVCAR3) were subcutaneously implanted for a tumor source and ovarian orthotopic transplantation. The cancer tissue, proximal paraneoplastic tissue, middle paraneoplastic tissue, remote paraneoplastic tissue, and normal ovarian tissue were removed. CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was detected by reverse transcription polymerase chain reaction. We obtained 35 paraneoplastic residual ovarian tissues with normal biopsies from 40 cases of an orthotopic epithelial ovarian carcinoma model (87.5%). CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was lower in proximal paraneoplastic tissue than in cancer tissue (P < 0.05) and higher than in middle and remote paraneoplastic tissue (P < 0.01). There was no statistically significant difference between the expression of these genes in middle and proximal paraneoplastic tissue as well as among residual normal ovarian tissues with different severity (P > 0.05). In ovarian tissues of 20 normal nude mice, the expression of CK- 7, CA125, p53, survivin, MMP-2, and TIMP-2 was negative. Overall, the expression levels of CK-7, CA125, p53, survivin, MMP-2, TIMP-2, and other molecular markers showed a decreasing trend in the non-cancer tissue direction. The expression levels can be used as standards to screen residual normal ovarian tissue. We can obtain relatively safe normal ovarian tissues adjacent to epithelial ovarian cancer.

In this paper, we reported the realization of an ultra-long ring fiber laser (RFL) with hybrid emission related to both random lasing and cavity resonance. Compared with a linear random fiber laser (LRFL), the Rayleigh scattering (RS) inducting distributed feedback effect and the cavity inducting resonance effect exist simultaneously in the laser, which reduces the lasing threshold considerably and provides a hybrid way to form random lasing (RL). The laser output can be purely modeless RL when pump power is high enough. It is also discovered that the laser is insensitive to temperature variation and mechanical disturbance, this is unique and quite different from conventional RFLs which are environmentally unstable due to existence of the cavity modes.
