Objective:To explore the clinical phenotype and genetic characteristics of children with childhood absence epilepsy caused by KMT2E gene variants. Methods:The clinical data of 1 case of KMT2E gene variant-associated childhood absence epilepsy admitted to the Department of Pediatric Neurology of Linyi People′s Hospital in January 2023 were collected and followed up, and the child and her family were genetically examined by using whole-exome sequencing and Sanger sequencing, and the pathogenicity of mutation loci was analyzed. The Online Mendelian Inheritance in Man, Human Gene Mutation Database, PubMed database, China National Knowledge Infrastructure, and Wanfang database were consulted with the search term " KMT2E" to summarize the clinical phenotype and genetics of the children with epilepsy associated with KMT2E gene variant. Results:The child is a female, presented with typical absence seizures at the age of 3 years and 8 months, with normal development, video electroencephalogram showing widespread spikes and slow waves around 3 Hz accompanied by typical absence seizures. Seizures decreased after valproic acid was applied at full dosage, and were controlled after combination with lamotrigine. Her clinical diagnosis of childhood absence epilepsy was made. The results of whole-exome sequencing showed that the child had a de novo frameshift variant c.2404dup (p.Arg802Lysfs *8) in the KMT2E gene (NM_182931.3), which had not yet been reported domestically or internationally. The c.2404dup variant was interpreted as a pathogenic variant (PVS1+PS2_Supporting+PM2_Supporting) according to the American Society of Medical Genetics and Genomics variant classification criteria and guidelines. Her parents, older brother and younger sister did not carry the variant and had a normal clinical phenotype. A total of 22 patients with epilepsy associated with KMT2E gene variants were retrieved (including this case, a total of 23 cases), including 10 females and 13 males. All of them were autosomal dominant inheritance, with 20 minor variations, including 8 frameshift variants, 7 missense variants, 2 splicing variants, 2 nonsense variants, 1 synonymous variant, and the remaining 3 cases had large fragment deletions (including 2 cases of the whole gene). Clinical manifestations mainly included epileptic seizures (5 cases of absence seizures, 7 cases of focal seizures with or without secondary tonic-clonic seizures, 9 cases of tonic-clonic seizures, 1 case of spasm seizures, 1 case of myoclonic seizures, tonic seizures, and atonic seizures, 3 cases of epileptic status, and 5 cases of refractory epilepsy, with the onset age of epilepsy ranging from neonatal to adolescence), mental retardation (21/23 cases, 4 mild, 5 moderate, and 5 severe), peculiar facial features (11/23), and autism (3/23), etc. Conclusion:KMT2E gene variant-associated epilepsy is an autosomal dominant disorder with a wide spectrum of clinical phenotypes, and the novel variant c.2404dup in the KMT2E gene identified in the present study can lead to childhood absence epilepsy, which enriches the spectrum of mutations and clinical phenotype of the KMT2E gene.

Based on the six core areas of knowledge, skills, optimism, outcome beliefs, environment and resources, and emotions, they should deeply explore the factors that affect their sexual health, provide professional guidance and comprehensive care, and improve their sexual health level and quality of life.

Objective: To examine the effects of high intensity interval training (HIIT) on body composition and cardiorespiratory fitness of obese primary school students, so as to provide a theoretical basis and practical reference for HIIT exercise prescription in schools. Methods: From August to December 2022, 25 obese children [age:(11.0±0.4)years, BMI:(23.3±0.8)kg/m 2] from a primary school in Shenzhen were recruited and divided into an exercise group ( n =13) and a control group ( n =12). After 12 weeks of exercise intervention [The durations of load period and intermittent period were 15 s, load exercise intensity was 100% maximal aerobic speed (MAS), and intermittent exercise intensity was 50% MAS, each time there were 2 groups× 8 rounds, and the rest between groups was 2 minutes, totaling 10 minutes, and 20 meter shuttle run test (20 m-SRT) was performed once every 4 weeks to adjust and update MAS], the changes in body composition and cardio respiratory fitness indexes of obese subjects before and after the intervention were compared. Results: After the intervention, body weight, BMI, body fat, body fat percentage, and visceral adipose tissue area of obese subjects in the exercise group decreased from (55.6±6.2)kg, (22.7±0.6)kg/m 2, (41.8±6.9)kg, ( 23.4± 5.5)% and (102.4±39.0)cm 2 to (52.3±5.8)kg, (21.1±0.8)kg/m 2, (38.6±6.3)kg, (20.2±4.5)% and (84.2±26.9)cm 2, respectively( t =8.73, 10.96, 7.02, 4.92, 4.95, P <0.05). SBP decreased from (115.4±9.7)mmHg to (112.3±8.7)mmHg ( t = 2.96 , P <0.05). The content of skeletal muscle, 20 m-SRT and VO 2max increased from (21.3±5.3)kg, (21.6±4.9) times and (39.4±2.0)mL/(kg ·min) to (21.8±5.2)kg, (31.4±6.3)times and (43.6±2.6)mL/(kg ·min), respectively ( t =-3.33, -8.37, -10.56 , P <0.05). Conclusions HIIT is an effective way to improve the body composition and cardiorespiratory fitness of obese primary school students. It is recommended that schools with the necessary conditions use this method as an intervention measure to help reduce weight and improve cardiovascular health among obese students.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

Conclusions:Compared with cases undergoing TLDG directly, the operation time to TLDG and time to drainage tube removal after TLDG for cases undergoing ESD+TLDG are prolonged, but there is no difference in the short-term efficacy. For cases undergoing TLDG ≤21 days after ESD and cases undergoing TLDG >21 days after ESD, there is a significant difference in the operation time of TLDG.

Objective To explore the value of multi-modal MRI in the differential diagnosis of pure fibroadenosis and mixed fibroadenosis in the breast. Methods Forty female patients who underwent 3.0 T MRI within 1 week before sugery and confirmed as breast fibroadenosis by pathology in the General Hospital of the PLA Rocket Force from January 2014 to May 2016 were retrospectively analyzed in this study. There were 20 cases of pure fibroadenosis which including mass type and non-tumor type, 10 cases per type. Twenty cases of mixed fibrous adenosis which including 4 cases of mass type and 16 cases of non-mass type. According to the breast imaging reporting and data system-MRI standard, conventional MRI features, time intensity curve (TIC) types and ADC values of the lesions were observed. MRI features and ages of pure fibroadenosis and mixed fibroadenosis were compared using χ2 test (qualitative data) and independent sample t test (quantitative data), P<0.05 was considered statistically significant. Statistically significant parameters were then used to perform logistic regression analysis to evaluate predictive value . The efficacy of each MRI parameter in the differential diagnosis of pure fibroadenosis and mixed fibroadenosis was analyzed by ROC. Results Statistically significant differencein the size(P<0.05) but no differences in the shape, T2WI manifestation, marginal, internal enhancement, early enhancement curve, and late enhancement (P>0.05) were observed between pure fibroadenosis and mixed fibroadenosis. There was no significant differences in distribution, internal enhancement, early enhancement curve and late enhancement curve between non-tumor type pure fibroadenosis and mixed fibroadenosis (P>0.05). There were significant differences in age, ADC value and peak signal intensity(P<0.05) while no significant differences in early enhancement rate, maximum enhancement rate and peak time (P>0.05) between patients with pure fibroadenosis and mixed fibroadenosis. Logistic regression analysis suggested that the peak signal intensity was closely related to age. It revealed a positive correlation between ADC value, peak signal intensity and the possibility of mixed fibroadenosis. The regression coefficient value, Wals value, and P value of the ADC value were 3.652, 4.363 and 0.034, respectively. The regression coefficient value, Wals value, and P value of the peak signal intensity were 0.005, 5.463 and 0.019, respectively. The area under ROC curve of ADC value, peak signal intensity, ADC value combined with peak signal intensity were 0.697, 0.701 and 0.786, respectively. Conclusions Significantly differences of peak signal intensity and ADC value were observed in mixed fibroadenosis compared with pure fibroadenosis. The combination of ADC value and peak signal intensity had the highest efficacy in predicting pure and mixed fibroadenosis.

Objective To investigate the effect of polyphosphazene(PAGP) microspheres controled release of growth factors on the adhesion and proliferation of bone marrow mesenchymal stem cells (BMSCs).Methods Two kinds of functional poly(alanine ethyl ester-co-glycine ethyl ester) phosphazene microspheres with different ratios of side-substituent groups were synthesized using the emulsion technique.The rate of degradation/hydrolysis of the polymers was carefully tuned to suit the desired application for controlled release.The enzyme-linked immune sorbent assay was utilized to investigate the characterization of the temporal controlled release strategy of microspheres loaded with transforming growth factor-beta 1(TGF-β1) and insulin-like growth factor-l(IGF-1) respectively.The cell adhesion and proliferation stimulated by different growth factors were evaluated by acridine orange staining.Resuits The morphological difference between two PAGP microspheres was identified according to SEM images.The average diameter of two microspheres was 54.22 ± 19.19 μm and 34.11 ± 18.82 μm respectively.The release assay showed that two kinds of microspheres had different release characteristics,with earlier outburst of TGF-β1 and IGF-1 for them to cooperate and later sustained release of TGF-β1 to stimulate the differentiation of stem cells.The result of the acridine orange staining demonstrated that PAGP microspheres supported cell adhesion and growth without obvious cytotoxicity.Meanwhile,the growth factors release strategy significantly improved the proliferation of BMSCs.Conclusion The two polyphosphazene microspheres have a great release-control effect and their controlled release system will have a promising prospect in the future tissue engineering field.

Objective To analyze the clinicopathologic factors affecting the formation of lymphovascular invasion (LⅥ) in patients with gastric cancer.Methods The retrospective case-control study was conduted.The clinicopathologic data of 1 260 patients with gastric cancer who were admitted to the First Affiliated Hospital of Nanjing Medical University between January 2014 and December 2015 were collected.All the surgical specimens of patients were detected by hematoxylin-eosin (HE) stain and diagnosed by pathological experts.Stages of patients were evaluated by the seventh TNM staging system for gastric cancer of American Joint Committee on Cancer (AJCC) and Union for International Cancer Control (UICC).Observation indicators:(1) pathologica features:histological differentiation,invasive depth,lymph node metastasis and TNM staging;(2) follow-up situations;(3) influenced factors of the positive LⅥ:sex,age,histological differentiation,invasive depth,number of lymph node metastasis and TNM staging affecting positive LⅥ were analyzed.Follow-up using outpatient examination and telephone interview were performed to detect survival of patients up to June 2016.Univariate analysis was done using the chi-square test,and multivariate analysis was done using the trend chi-square test,and binary Logistic regression model.Results (1) Pathological features:1 260 patients with gastric cancer were diagnosed by postoperative pathological examinations,including 355 with positive LⅥ and 905 with negative LⅥ.Histological differentiation:high-differentiated tumor was detected in 13 patients,moderate-differentiated tumor in 232 patients and low-differentiated tumor in 775 patients.There were 95 patients with mucinous adenocarcinoma and 145 with signet-ring cell carcinoma.Invasive depth:tumor invasion into mucosal layer or submucosal layer (T1 stage) was detected in 242 patients,muscular layer (T2 stage) in 160 patients,gastric wall layer and no invasion into serosal layer (T3 stage) in 37 patients and subserosal layer (T4 stage) in 821 patients.Lymph node metastasis:no regional lymph node metastasis (N0 stage) was detected in 461 patients,1-2 lymph nodes metastases (N1 stage)in 164 patients,3-6 lymph nodes metastases (N2 stage) in 245 patients and more than 7 lymph nodes metastases (N3 stage) in 390 patients.TNM staging:there were respectively 191 patients in Ⅰ A stage,114 in Ⅰ B stage,62 in ⅡA stage,202 in ⅡB stage,132 in ⅢA stage,80 in ⅢB stage,476 in ⅢC stage and 3 in Ⅳ stage.(2)Follow-up situations:1 142 patients (320 with positive LⅥ and 822 with negative LⅥ) were followed up for 4.0-24.0 months,with a meidan time of 11.0 months and a follow-up rate of 90.635％ (1 142/1 260).During the follow-up,154 patients died,including 41 with positive LⅥ and 113 with negative LⅥ.(3) Influenced factors of the positive LⅥ:① results of univariate analysis showed that histological differentiation,invasive depth,number of lymph node metastasis and TNM staging were factors affecting positive LⅥ of patients with gastric cancer (X2=16.930,29.190,64.463,46.539,P＜0.05).② Results of the trend chi-square test showed that histological differentiation,invasive depth,number of lymph node metastasis and TNM staging were factors affecting positive LⅥ of patients with gastric cancer,with a linear correlation (X2 =54.883,69.130,164.618,119.594,r=0.211,0.243,0.365,0.316,P＜0.05).There was a greater correlation between number of lymph node metastasis and formation of lymphovascular invasion.③ Results of the binary Logistic regression model showed that moderate-and low-differentiated tumor and N1-N3 stage of lymph node metastasis were independent risk factors affecting positive LⅥ of patients with gastric cancer (OR=2.572,1.782,95％ confidence interval:0.495-1.494,0.386-0.781,P＜0.05).Conclusion Patients with lower tumor differentiation and / or greater number of lymph node metastasis may have a higher risk of forming LⅥ.

Objective To survey the awareness and knowledge of Helicobacter pylori (Hp) infection among medical staff in Shanghai.Methods A questionnaire survey was conducted among 316 medical staff in Shanghai,including 74 gastroenterologists (GI),158 general practitioners (GP),and 68 gastroenterology nurses(GN),from October 2014 to September 2015.The questionnaire was designed according to the Fourth Helicobacter Pylori Infection Treatment Consensus Report of China (the Consensus).There were 4 parts and 29 questions in the questionnaire,including the knowledge and performance of the Consensus (8 questions),the indications of Hp eradication (8 questions),detection methods of Hp infection (7 questions)and the therapy of Hp eradication (6 questions).Results Total 300 valid questionnaires were received with a response rate of 94.9％ (300/316).The awareness rate of the Consensus in GI,GP and GN groups was 81.1％ (60/74),57.6％ (91/158) and 26.4％ (18/68),respectively (χ2 =43.67,P=0.001).GI had higher awareness rate than GP and GN in indications of Hp eradications (for peptic ulcer,mucosa-associated lymphoid malignancies,post-resection patients of early gastric cancer,and family history of gastric cancer,the χ2 values were 16.68,35.60,33.46 and 39.22,respectively;all P ＜0.05).In part of Hp infection detection methods,the responses of GI,GP and GN groups in C14 or C13 urea breathing test were 97.3％ (72/74),47.5％ (75/158) and 82.1％ (55/68),respectively (χ2 =72.38,P =0.001);in gastric mucosa tissue rapid urease test were 70.3％ (52/74),13.9％ (22/158) and 25.4％ (17/68),respectively (χ2 =78.22,P =0.001);in serological test were 58.1％ (43/74),20.9％ (33/158)and 44.8％ (30/68),respectively (χ2 =40.30,P =0.001);in gastric mucosa tissue section staining were 56.8％ (42/74),13.3％ (21/158) and 22.4％ (15/68),respectively (χ2 =50.35,P =0.00).In part of Hp eradication therapy the responses of GI,GP and GN groups in recommended bismuth quadruple therapy were 71.6％ (53/74),47.5％ (75/158) and 40.3％ (25/62),respectively (χ2 =15.93,P =0.001);in triple therapy were 27.0％ (20/74),51.6％ (81/158) and 42.0％ (26/62),respectively (χ2 =12.42,P =0.002);in 10 or 14 d for treatment duration were 78.4％ (58/74),78.5％ (124/158)and 67.6％ (46/68),respectively (χ2 =3.36,P =0.186).Conclusion Gastroenterologists are more likely to adhere with the Consensus than general practitioners and gastroenterological nurses in the management of Hp infection.The survey suggests that more attention should be paid for popularization and implementation of Hp infection guidelines and consensus among Shanghai medical staff,especially for GP and nurses.
