ABSTRACT

Retrospective analysis was performed on 1 child with silent inactivation (SI) of asparaginase (ASNas) who was diagnosed with acute lymphoblastic leukemia (ALL) and treated in the First Affiliated Hospital, Sun Yat-Sen University in October 2019.The patient was a 9 years and 3 months old boy who was diagnosed as ALL accompanied with late bone marrow relapse.After pegylated Escherichia coli-Asparaginase (PEG-ASNase) was given, he did not have the expected treatment-related adverse reactions, including hyperammonemia, hypofibrinogenemia, and the low activation of antithrombin Ⅲ (ATⅢ). The plasma asparagine (ASN) concentration failed to meet the depletion criteria and the ASNase activity was 64.5 U/L.Therefore, the SI of ASNase was confirmed.Erwinase was used to replace PEG-ASNase, the lowest level of ATⅢ was 33%, and the lowest level of fibrinogen was 1.20 g/L.Hyperammonemia and decreased ASN were also observed, and the ASNase activity was 1 813.0 U/L.All the above suggested that when, SI occurred, the replacement by Erwinase was effective.The ASNase activity should be monitored in ALL patients who were treated with ASNase.Monitoring the treatment-related adverse reactions such as hyperammonia and coagulation disorders closely has important implications to the SI of ASNase when the detection of ASNase activity was unavailable.

ABSTRACT

Objective:To investigate the effects of fasting blood glucose levels on the quality of myocardial metabolism imaging via positron emission tomography/X-ray computed tomography(PET/CT)in patients with coronary heart disease.Methods:A total of 78 patients with coronary heart disease from 2019 to 2020 undergone 18-fluorine deoxyglucose( 18F-FDG)PET/CT myocardial imaging in Beijing Anzhen Hospital were retrospectively analyzed, with 64 patients meeting the inclusion criteria eventually enrolled in this study.All patients fasted over 8 hours and were injected with insulin and 18F-FDG following an oral glucose load.Then myocardial imaging evaluations were performed.Depending on whether the myocardial image quality(IQ)offered a match with clinical diagnosis, a score between 0-2 from the semiquantitative scoring system was defined as good IQ, while a score between 3-4 defined as poor IQ.Differences in sex, age, rate of diabetes, body mass index, fasting blood glucose(FBG), glycosylated hemoglobin, glycosylated serum albumin, triglycerides and free fatty acids, lipid-regulating drugs, and oral antidiabetic medications were analyzed between the good( n=55)and poor( n=19)image groups, and risk factors were examined. Results:The diabetes mellitus rate was higher in the poor group than in the good group(63.2% vs.33.3%, χ2=4.872, P=0.027). FBG, glycosylated hemoglobin and glycosylated serum albumin levels in the poor group were increased compared with the good group[7.67(6.02, 11.64)mmol/L vs.5.52(4.97, 6.37)mmol/L, 7.30(6.43, 8.70)% vs.6.20(5.60, 6.87)%, 19.8(15.1, 24.1)% vs.14.8(13.9, 16.8)%, U=-3.909, -2.419 and -3.042, P<0.001, P=0.016 and 0.002, respectively]. Multivariate Logistic regression analysis showed that FBG was an independent risk factor for poor imaging( OR=1.62, 95% CI: 1.19-2.20, P=0.002). The area under the receiver operator characteristic(ROC)curve for FBG was 0.811(95% CI: 0.69-0.93, P<0.001), and the cut-off value for FBG was 6.66 mmol/L. Conclusions:FBG is an independent risk factor for myocardial image quality.Patients with diabetes mellitus should rigorously control their blood glucose levels.

ABSTRACT

Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for three children with Menkes disease.@*METHODS@#The patients were subjected to next-generation sequencing (NGS) to detect potential variants of the ATP7A gene. Suspected variants were verified by Sanger sequencing of their family members and 200 healthy individuals. Multiplex ligation-dependent probe amplification (MLPA) was also carried out to detect potential deletions in their family members and 20 healthy individuals.@*RESULTS@#Variants of the ATP7A gene were detected in all of the three families, including a novel c.1465A>T nonsense variant in family 1, a novel c.3039_3043del frame-shifting variant in family 2, and deletion of exons 3 to 23 in family 3, which was reported previously. Based on the standards and guidelines of American College of Medical Genetics and Genomics, the c.1465A>T and c.3039_3043del variants of ATP7A gene were predicted to be likely pathogenic (PVS1+PM2).@*CONCLUSION@#Variants of the ATP7A gene may underlay the Menkes disease in the three children. Above findings have facilitated clinical diagnosis and enriched the spectrum of genetic variants of Menkes disease.

ABSTRACT

OBJECTIVE: To explore the role of N~6-methyladenosine(m~6A) catalytic enzymes(methyltransferases and demethylases) in cadmium-induced oxidative damage in human renal epithelial cells(HK-2 cells), and to analyze the correlation between nuclear factor-erythroid 2-related factor 2(NRF2) and m~6A catalytic enzymes. METHODS: i) HK-2 cells in logarithmic growth phase were randomly divided into control group and 6 cadmium sulfate treatment groups, then treated with 0, 2, 4, 8, 16, 32 and 64 μmol/L cadmium sulfate solution for 24 hours. The cell survival rates were detected by CCK-8 assay, and the appropriate doses of cadmium sulfate were selected for subsequent experiments. ii) HK-2 cells in logarithmic growth phase were randomly divided into control group and low-, medium-, and high-dose groups, and treated with 0, 4, 8, and 16 μmol/L cadmium sulfate solution respectively for 24 hours. Subsequently, the levels of reactive oxygen species(ROS) were detected by fluorescence probe. The mRNA expression of NRF2, the m~6A methyltransferases such as methyltransferase like proteins(METTL) 3, METTL14, METTL16 and the m~6A demethylases such as fat mass and obesity associated protein(FTO), AlkB family of nonheme Fe(Ⅱ)/α-ketoglutarate(α-KG)-dependent dioxygenases 5(ALKBH5) were determined by real-time polymerase chain reaction. RESULTS: i) The survival rate of HK-2 cells was more than 60.00% and lower than that of the control group(P<0.05) after the cells were stimulated with 16 μmol/L of cadmium sulfate. Therefore, 4, 8 and 16 μmol/L of cadmium sulfate were selected as the stimulation concentrations in the follow-up experiments. ii) The relative expression of NRF2, METTL3, METTL14 and METTL16 in HK-2 cells in low-dose group increased(all P<0.05), while the levels of ROS and the relative mRNA expression of NRF2, METTL3, METTL14, METTL16 and FTO in HK-2 cells in medium and high-dose groups increased(all P<0.05) when compared with the control group. There was no significant difference in the expression of ALKBH5 mRNA among these 4 groups(P>0.05). In the correlation analysis, NRF2 mRNA expression was positively correlated with the mRNA expression of METTL3 and METTL16 [Pearson correlation coefficient(r) = 0.61 and 0.66, respectively, all P<0.05]. There was no correlation between NRF2 mRNA expression and METTL14, FTO and ALKBH5(r=0.53, 0.48, and 0.01 respectively, all P>0.05). CONCLUSION: Cadmium sulfate may increase intracellular ROS level, up-regulate NRF2 expression and activate NRF2 signaling pathway as well as enhance the expression of METTL3 and METTL16 in HK-2 cells, thus increasing intracellular oxidative damage and decreasing the cell survival rate.

ABSTRACT

Objective:To summarize the clinical features and PLGL gene variation characteristics of children with CHIME syndrome. Methods:The medical records of one patient who was diagnosed with CHIME syndrome in the Third Affiliated Hospital of Zhengzhou University in October 2018 were analyzed.Foreign and domestic databases were searched with " CHIME syndrome or PIGL gene" as the keywords, so as to review clinical features of CHIME syndrome and PIGL gene variation characteristics. Results:(1) The boy, 1 year old and 3 months, developed seizures at the age of 7 months, when he received rehabilitation due to developmental delay.Physical examination showed that the boy had facial dysmorphisms, including high forehead, ocular hypertelorism, low and flat nasal root, broad nose tip, full lips, overfolded helices, cleft palate, developmental delay, dry skin, erythematous papular rash on the neck, and indirect inguinal hernia. Conductive deafness was revealed by the hearing test and retinal defect was found in fundus examination.Whole exome sequencing test identified PIGL(NM_004278)gene compound hybrid variation.The frameshift variation c. 26delT was present in one allele, combined with a synonymous variation c. 333C>T in the opposite allele.(2) A total of 9 CHIME syndrome patients were retrieved from the databases.No cases were reported in China.All 9 patients had craniofacial dysmorphism, epilepsy, conductive deafness, development delay and retinal defect.Eight patients had ichthyosiform skin, 6 patients had congenital heart disease and 4 patients had renal malformation.There were 6 different kinds of PIGL gene variations in patients, including 7 missense variants, 4 frameshift variants, 3 deletion variants, 2 nonsense variants, 1 splice variant, and 1 synonymous variant. All of the missense variants were c. 500T>C (p.Leu167Pro), which was the most common site. Conclusions:CHIME syndrome is mainly manifested by nervous system and dermal system abnormalities, and often involves multiple systems. PIGL gene variation is the cause of CHIME syndrome, and c. 500T>C (p.Leu167Pro) is the most common site.

ABSTRACT

Hepatitis B is a major public health problem in China. Nucleoside/nucleotide analogues and interferon(IFN) can effectively inhibit the replication of hepatitis B virus, but the treatment effect is still not so effective because cccDNA cannot be completely removed. IFNλ is a newly discovered family of cytokines that induces antiviral, antiproliferative and antitumor effects by activating the Jak-STAT pathway. Recent studies have found that IFNλ is also of great significance in hepatitis B as a therapeutic agent and immunological indicator. IFNλ can effectively inhibit the replication of hepatitis B virus, while the gene polymorphisms of IFNλ are closely related to prognosis and susceptibility to hepatitis B; and IFNλ also shows a certain anti-tumor activity in hepatitis B-related hepatocellular carcinoma. IFNλ is expected to be used as a clinical adjuvant treatment for patients with hepatitis B. This article describes the current research progress on IFNλ in hepatitis B.

ABSTRACT

Chronic hepatitis B (CHB) is an infectious disease characterized by liver damage, which can progress to liver fibrosis, cirrhosis, liver failure or liver cancer, threatening the life of patients. CHB patients are prone to be complicated with hepatitis B virus-associated glomerulonephritis and other kidney diseases, therefore the renal safety should be fully considered in the antiviral treatment of CHB patients. According to current guidelines, telbivudine, entecavir or tenofovir alafenamide are recommended for CHB patients with renal insufficiency or potential renal injury, but each has its advantages and disadvantages. How to carry out antiviral treatment in CHB patients with renal impairment deserves our attention. At the same time, the renal function should be monitored regularly in the course of antiviral treatment to identify the damage of renal function in the early stage. This article reviews the causes of renal dysfunction in CHB patients, the risk of kidney damage during the antiviral treatment, the choices of antiviral therapy and the monitoring of renal function in the patients.

ABSTRACT

Objective:To evaluate the clinical value of 18F-fluorodexoyglucose (FDG) PET/CT in distinguishing benign from malignant tumors in patients with cardiac tumors. Methods:Between January 2015 and September 2018, 18F-FDG PET/CT was performed in 3 678 patents in Beijing Anzhen Hospital, and 51 of them (51/3 678, 1.39%) were diagnosed as cardiac tumors. Finally, 28 patients (10 males, 18 females; mean age (52±14) years, age range: 18-84 years) with pathological results were included. According to pathological results, patients were divided into 4 groups: group 1 with primary benign cardiac tumor ( n=9), group 2 with primary malignant cardiac tumor ( n=9), group 3 with lymphoma ( n=6) and group 4 with secondary malignant cardiac tumor ( n=4). All patients underwent early (60 min) 18F-FDG PET/CT imaging and 22 patients (6, 7, 6, 3 patients in group 1, group 2, group 3, group 4 respectively) underwent delayed (120 min) imaging. The maximum standardized uptake value (SUV max) and target/backgroud ratio (TBR) of 4 groups in early imaging and delayed imaging were calculated and compared with one-way analysis of viariace and Scheffe Post-hoc test. TBR were calcualted as SUV max/mean standardized uptake value (SUV mean) in the liver. Receiver operating characteristic (ROC) curve analysis was also performed. Results:SUV max during early imaging, defined SUV max(early), was 2.6±1.5, 9.9±4.0, 20.5±6.1, 9.2±5.8 in group 1-4 respectively ( F=21.39, P<0.01), the value of group 1 was lower than that of group 2 and 3, and the value of group 3 was the highest (all P<0.005). TBR early was 1.1±0.6, 4.1±1.6, 9.4±2.6, 3.7±2.0 in the 4 groups ( F=29.15, P<0.01), the value of group 1 was lower than that of group 2 and 3, and the value of group 3 was the highest (all P<0.005). SUV max in delayed imaging (SUV max(delay)) was 2.4±1.2, 11.0±5.9, 25.8±7.7, 13.7±7.7 respectively in the 4 groups ( F=16.01, P<0.01). TBR delay was also significantly different among the 4 groups (1.3±0.7, 5.5±2.9, 14.4±4.9, 7.9±5.0; F=14.78, P<0.01), the value of group 3 was higher than that of group 1 and 2 (all P<0.05). ROC curve analysis showed optimal cut-off values for indicating malignancy were: SUV max(early)=4.2, TBR early=1.6, SUV max(delay)=4.6, TBR delay=1.9. The corresponding sensitivities, specificities, accuracies were 19/19, 8/9, 96.4%(27/28); 19/19, 7/9, 92.9%(26/28); 16/16, 6/6, 100%(22/22); 16/16, 5/6, 95.5%(21/22), respectively. Conclusions:18F-FDG PET/CT imaging can accurately diagnose malignant cardiac tumors. Delayed imaging can further improve the accuracy for diagnosis of malignant cardiac tumors.

ABSTRACT

Objective:To evaluate the image quality (IQ) of 18F-fluorodeoxyglucose (FDG) PET/CT imaging and identify its influenfial factors in diabetes mellitus (DM) and non-DM patients with coronary artery disease (CAD). Methods:A total of 196 consecutive CAD patients (174 males, 22 females, 68 DM; age: (57±10) years) in Beijing Anzhen Hospital between June 2016 and February 2018 were retrospectively analyzed. All patients underwent 18F-FDG myocardial PET/CT imaging. The standardized fasting+ oral glucose loading (OGL) and intravenously injection of insulin protocol was performed. According to the FDG uptake by myocardium, background activity in blood and other visceral organ nearby the heart, the IQ was visually evaluated and scored by 0-4. Zero-two was considered as good IQ, 3-4 was regarded as poor IQ. Patients were divided into three groups: group 1 (non-DM+ good IQ), group 2 (DM+ good IQ), group 3 (DM+ poor IQ). Factors which may affect IQ were analyzed, which including OGL, the injection dose of insulin, fasting blood glucose (FBG), peak blood glucose (PBG), blood glucose (BG) level at 18F-FDG injection (BG injnection), BG increasing rate ((PBG-FBG)/FBG, %), and BG decreasing rate ((PBG-BG injection)/PBG, %). One-way analysis of variance, Spearman correlation analysis and logistic regression analysis were used for data analysis. Results:There were significant differences ( F values: 13.074-38.371, all P<0.05) of FBG, PBG, OGL, BG decreasing rate and the injection dose of insulin among group 1 ( n=132, 67.3%), group 2 ( n=53, 27.1%), group 3 ( n=11, 5.6%). All those parameters, except for OGL, were positively correlated with FDG PET/CT IQ ( r s values: 0.142-0.262, all P<0.05). OGL was negatively correlated with IQ ( r s=-0.324, P<0.05). Logistic regression analysis showed that FBG (odds ratio ( OR)=0.687, 95% CI: 0.633-0.746), PBG( OR=0.786, 95% CI: 0.746~0.829), BG injection( OR=0.631, 95% CI: 0.595-0.716), OGL( OR=0.897, 95% CI: 0.873-0.922), the injection dose of insulin( OR=0.680, 95% CI: 0.618-0.748) were predictive factors (all P<0.01) for good IQ in all patients. For DM patients, OGL was the only predictive factor for good IQ( OR =0.940, 95% CI: 0.904-0.960; P<0.01). Conclusions:FBG, PBG, BG injection, OGL, the injection dose of insulin can predict IQ for all patients with CAD. For DM patients with CAD, OGL is the only predictive factor for good IQ. A good IQ of 18F-FDG PET/CT could be obtained in majority of CAD patients, with the standardized fasting + OGL and intravenously injection of insulin protocol and adjust according to the personal status, and prevent the hypoglycemia from happening.

ABSTRACT

Objective@#To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.@*Methods@#530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients.@*Results@#A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05).@*Conclusions@#Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It′s important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.

ABSTRACT

Background: Liver reserve function decreases with aging, and at the same time liver histomorphology is degenerated. The incidence and mortality rate of hepatic diseases in elderly people are higher than young people. Aims: To explore the changes and significance of biological molecules in liver tissue of elderly beagle dogs. Methods: Fifteen healthy beagle dogs were divided into young group and aged group. The contents of Bcl-2, Bax, TE, GSK-3, caspase-9, HA, LN, PCIII, Col and CYP1A2 were determined by ELISA. The content of GSH-Px was assessed by biochemical methods. mRNA and protein expressions of PDGF-B, TGF-β1, TGF-β3 were detected by fluorescent quantitative PCR and Western blotting, respectively. Results: Compared with the young group, the contents of regeneration-related molecules Bcl-2, Bax, TE, caspase-9 were significantly increased in aged group (P<0.05), GSK-3 was significantly decreased (P=0.013). The activity of antioxidant molecule GSH-Px and hepatic drug metabolic enzyme CYP1A2 were significantly decreased in aged group than in young group (P=0.012, P=0.006). The contents of liver fibrosis molecules LN, PCIII were significantly increased in aged group than in young group (P<0.05), however, no significant difference in contents of HA and Col were found between the two groups. The mRNA and protein expressions of PDGF-B and TGF-β1 were significantly increased in aged group than in young group (P<0.05); mRNA expression of TGF-β3 was significantly increased (P=0.035), however, the protein expression was significantly decreased (P=0.004). Conclusions: There are a series of molecular biology changes, which are the basis of histomorphological changes in liver tissue of elderly, and its underlying clinical value are deserved to be further studied and developed.

ABSTRACT

OBJECTIVE To discuss the correlation between effectual time and the curative effect in patients with all frequency descending sudden deafness. METHODS According to effectual time,the subjects were divided into first week effectual group and second week effectual group and the curative effect of each group was compared. RESULTS In patients with flat descent sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, but there was no significant difference between the two groups(χ2=1.599, P =0.206). Meanwhile, the total significant effective rate of the first week effectual group was higher than that of the second week effectual group, without obvious difference between the two groups(χ2=0.124, P =0.725). Furthermore, in patients with total deafness type of sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, showing no remarkable difference between the two groups(χ2=2.493, P =0.114). Besides, there was no remarkable difference in the comparison of the total significant effective rate (χ2=2.308, P =0.129), which was higher in the first week effectual group than that in the second week effectual group. CONCLUSION The course of treatment should be at least 2 weeks in patients with all frequency descending sudden deafness after onset.

ABSTRACT

Objective To explore the relationship between different mutation characteristics and clinical phenotype of children with Dravet syndrome (DS) with SCN1A gene mutation,and to summarize the drug efficacy.Methods The clinical data of children diagnosed as DS from the Department of Pediatrics Neurology,the Third Affiliated Hospital of Zhengzhou University from January 2014 to May 2018 were collected.The peripheral blood DNA of the children was detected by adopting next generation sequencing for epilepsy-related gene-panel,while the parents' were screened by using Sanger sequencing for family verification.Multiple ligation-dependent probe amplification technology was used to detect large fragment variation of SCN1A gene if the mutations of the children were negative.The Gesell scale and cavity Wechsler intelligence scale for children(C-WISC) were used to evaluate the intelligence of children.Results A total of 50 cases of DS were collected,38 cases of them were positive for SCN1A mutation,and the mutation rate was 76.0% (38/50 cases),of which,the missense mutation[50.0% (19/38 cases)] and frameshift mutation[28.9% (11/38 cases)] were dominant.The average onset age of 50 patients was 6 months,of which onset of seizures was triggered by fever(temperature > 37.5 ℃) in 68.0% (34/50 cases)of children,the history of seizures in hot baths was found in 60.0% (30/50 cases) of children,status epilepticus was found in 74.0% (37/50 cases),cluster-like episodes was found in 80.0% (40/50 cases),≥2 seizure types was found in 92.0% (46/50 cases).Mental retardation was found in most of the children,of which 30.0% (15/50 cases) were mild mental retardation,38.0% (19/50 cases) were moderate mental retardation,14.0% (7/50 cases)were severe intelligence retardation.Interictal abnormalities of electroencephalogram(EEG) before 1 year old was found in 24.0% (12/50 cases),and the average age of EEG abnormalities was 30.12 months old;the top three drug efficacy rates were 70.0% (28/40 cases) of Topiramate,48.0% (24/50 cases) of Sodium Valproate,45.7% (16/35 cases) Clonazepam or Clobazam.The time of onset of myoclonus and atypical absence of the truncation mutation group was earlier than that of the missense mutation group(14.75 months vs.21.20 months;16.82 months vs.26.00 months),and the difference was statistically significant (P < 0.05).The proportion of clustered episodes in the truncation mutation group was higher than that in the missense mutation group [94.7% (18/19 cases)vs.63.2% (12/19 cases)],and the difference was statistically significant (P <0.05).There was no significant correlation between the SCN1A gene mutation (type and position) and age of onset,type of seizure,proportion of convulsion persistence,the mental development or abnormal proportion of EEG and seizure frequency before 1 year old(all P > 0.05).Conclusions The SCN1A gene mutation rate is high in children with DS,and the SCN1A gene mutation characteristics has a certain correlation with DS clinical phenotype.Topiramate is the most effective drug among children with DS.
