Objective:To explore the clinical characteristics of interleukin-6 (IL-6) and interleukin-8 (IL-8) in cerebrospinal fluid (CSF) of children with bacterial meningitis (BM) and provide reference for clinical diagnosis and treatment of BM.Methods:The clinical data of BM children hospitalized in Women and Children′s Medical Center Affiliated to Guangzhou Medical University from December 2019 to March 2022 were collected and retrospectively analyzed in this case series study.Cytokines in CSF of these children were detected at least twice during the treatment. t test, Mann-Whitney test or analysis of variance were carried out for statistical analysis. Results:There were 40 patients included in this study.The age of onset was 2(1, 8) months, ranging from 2 days to 8 years, and the length of time from onset to hospitalization was (15±17) days, ranging from 1 day to 69 days.The main symptoms at the onset were fever (40 cases, 100%), poor mental state (16 cases, 35.0%), convulsion (9 cases, 22.5%), and vomiting (9 cases, 22.5%).According to pathogens, the patients were divided into the Streptococcus agalactia group (GBS group, 9 cases), Streptococcus pneumoniae group (SP group, 9 cases), other bacteria group (9 cases), and unknown bacteria group (13 cases).The levels of cytokines in the CSF of BM children were increased, along with significantly elevated levels of IL-6 and IL-8 within 1 st week of BM, followed by the peak at 2 nd-3 rd weeks, and then levels of IL-6 and IL-8 presented an overall decreasing trend with the progression of BM.The level of IL-6 in CSF of 10 cases significantly decreased in the 4 th week of BM [within 2 weeks: 773.5(164.1, 1 781.2) ng/L vs. 4 th week: 10.8(2.2, 21.1) ng/L, P=0.005].Such statistical differences didn′t occur to the level of IL-8 [within 2 weeks 182.9(33.6, 657.7) ng/L vs. 4 th week: 92.9(22.6, 226.6) ng/L, P=0.303].After effective antibiotic therapy, 6 patients had elevated white blood cell count in CSF during the 4 th-20 th weeks, with or without repeating intermittent fever.Among them, 4 cases of GBS and 1 case of SP were negative for pathogens in CSF during the retest after treatment, and the levels of IL-6 and IL-8 [(149.1-4 218.6) ng/L and (124.2-1 890.3) ng/L, respectively] in CSF were elevated.Low-dose glucocorticoid was administered for anti-inflammatory treatment, with additional gamma globulin for 1 case and Ibuprofen instead for 1 case.Subsequently, the fever completely subsided.The white blood cell count in CSF decreased significantly ( P=0.024). Conclusions:The levels of IL-6 and IL-8 in CSF increase significantly in the acute phase of BM and generally decrease with the progression of BM.If they are still significantly elevated in the later course of BM, it should be noted that an intracranial hyperinflammatory response may occur, especially when the pathogenic bacteria are GBS or SP.

Objective:To explore the correlation between clinical phenotypes and genotypes among 46 children with SCN1A-related developmental epileptic encephalopathy (DEE). Methods:Clinical data of 46 children with DEE and SCN1A variants identified at the Guangzhou Women and Children′s Medical Center between January 2018 and June 2022 were collected. The children were grouped based on their age of onset, clinical manifestations, neurodevelopmental status, and results of genetic testing. The correlation between SCN1A genotypes and clinical phenotypes was analyzed. Results:Among the 46 patients, 2 children (4.35%) had developed the symptoms before 3 months of age, 42 (91.30%) were between 3 to 9 months, and 2 cases (4.35%) were after 10 months. Two cases (4.35%) presented with epilepsy of infancy with migrating focal seizures (EIMFS), while 44 (95.7%) had presented with Dravet syndrome (DS), including 28 cases (63.6%) with focal onset (DS-F), 13 cases (29.5%) with myoclonic type (DS-M), 1 case (2.27%) with generalized type (DS-G), and 2 cases (4.55%) with status epilepticus type (DS-SE). Both of the two EIMFS children had severe developmental delay, and among the DS patients, 7 cases had normal development, while the remaining had developmental delay. A total of 44 variants were identified through genetic sequencing, which included 16 missense variants and 28 truncating variants. All EIMFS children had carried the c. 677C>T (p.Thr226Met) missense variant. In the DS group, there was a significant difference in the age of onset between the missense variants group and the truncating variants group ( P < 0.05). Missense variants were more common in D1 (7/15, 46.7%) and pore regions (8/15, 53.3%), while truncating variants were more common in D1 (12/28, 42.9%). Children with variants outside the pore region were more likely to develop myoclonic seizures. Conclusion:The clinical phenotypes of DEE are diverse. There is a difference in the age of onset between individuals with truncating and missense variants in the SCN1A gene. Missense variants outside the pore region are associated with a higher incidence of myoclonic seizures.

【Objective】 To investigate the common etiology, characteristics and treatment of iatrogenic ureteral stricture. 【Methods】 The clinical data of 226 patients with ureteral stricture repaired during May 2019 and Mar. 2022 were retrospectively analyzed, including 68 cases of iatrogenic ureteral stricture. According to the etiology, the patients were divided into urinary group and non-urinary group. 【Results】 There were 42 females and 26 males, aged 25 to 67 (average 49.0±10.4) years. Upper ureteral stricture was detected in 24 (35.3%) cases, who received oral mucosal repair of the ureter. Middle ureteral stricture was detected in 12 (17.6%) cases, who underwent ileal ureterography. Lower ureteral stricture was observed in 24 (35.3%) cases, who were treated with vesical wall flap ureteroplasty. Full-length stricture was observed in 8 (11.8%) cases,who were treated with ileal ureterography. There were significant differences in age, gender, stenosis side, stenosis location and length, surgical methods and types between patients in the urinary group and non-urinary group (P<0.05). During the follow-up of 8 to 20 (average 12.3±5.6) months, the symptoms and renal function of all patients improved, and no recurrence occurred. 【Conclusion】 Invasive endourological surgery is the most common cause of iatrogenic ureteral stenosis. Different treatment strategies should be adopted according to patients’ condition, time of diagnosis and location and length of ureteral injury.

Objective:To investigate the prognosis of robotic pancreatoduodenectomy after the learning curve and open pancreatoduodenectomy for pancreatic cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 396 patients who underwent curative pancreatoduodenectomy for pancreatic duct adenocar-cinoma in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from January 2017 to December 2018 were collected. There were 244 males and 152 females, aged 64(range, 36?92)years. Of 396 patients, 86 cases undergoing robotic pancreatoduodenectomy were divided into robotic group, 310 cases undergoing open pancreatoduodenectomy were divided into open group. Observa-tion indicators: (1) propensity score matching and comparison of general data between the two groups after matching; (2) follow-up and survival analysis. Follow-up was conducted by telephone interview or outpatient examinations including tumor markers and abdominal imaging examina-tions to detect survival of patients up to March 2022. Overall survival was defined as the time from the surgery date to death or the last follow-up. Disease-free survival was defined as the time from the surgery date to tumor recurrence or the last follow-up. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Normality of measurement data was examined using the Shapiro-Wilk test. Measurement data with skewed distribution were described as M(range), and comparison between groups was analyzed using the Mann-Whitney rank-sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used for survival analysis. An intent-to-treat analysis was performed in this study, patients who were converted to laparotomy from robotic surgery were still divided into the robotic group. Results:(1) Propensity score matching and comparison of general data between the two groups after matching: 164 of 396 patients had successful matching, including 82 cases in robotic group and open group, respectively. Before propensity score matching, the body mass index, cases in stage T1, T2, T3, T4, cases in N0, N1, N2 were 23.4(range, 21.4?25.3)kg/m 2,24, 41, 10, 11, 52, 27, 7 for the robotic group, versus 22.4(range,20.3?23.9)kg/m 2,57, 144, 22, 87, 131, 132, 47 for the open group, showing significant differences in the above indicators between the two groups ( Z=3.01, 2.63, 3.03, P<0.05). After propensity score matching, cases of males, age, body mass index, cases with American Society of Anesthesiologists (ASA) score as 1, 2, 3, CA19-9, cases with preoperative biliary drainage, cases with portal vein resection, cases with pancreatic resection margin <1 mm, cases in stage T1, T2, T3, T4, cases in stage N0, N1, N2, cases with nerve invasion, cases with tumor differentiation as high-medium differentiation, medium-low differentiation, low differentiation, cases with adjuvant chemotherapy were 51, 65(range, 59?69)years, 23.0(range, 21.0?25.2)kg/m 2, 32, 41, 9, 160.4(range, 46.7?377.2)U/mL, 21, 9, 8, 21, 40, 10, 11, 48, 27, 7, 76, 26, 47, 9, 53 for the robotic group, versus 58, 65(range, 58?69)years, 23.3(range, 21.4?25.3)kg/m 2, 35, 39, 8, 172.0(range, 69.7?402.9)U/mL, 26, 9, 10, 24, 40, 7, 11, 49, 28, 5, 76, 22, 49, 11, 57 for the open group, showing no significant difference in the above indicators between the two groups ( χ2=1.34, Z=0.18, 0.34, 0.49, 0.51, χ2=0.75, 0.00,0.25, Z=0.59, 0.27, χ2=0.00, Z=0.76, χ2=0.44, P>0.05). (2) Follow-up and survival analysis: after propensity score matching, 164 patients were followed up for 54(range, 1?67)months. The follow-up time of patients was 55(range, 51?59)months for the robotic group, versus 54(range, 50?58)months for the open group, respectively, showing no significant difference between the two groups ( Z=0.48, P>0.05). During the follow-up, the 1-year overall survival rate, 3-year overall survival rate, the median survival time, 1-year disease-free survival rate, 3-year disease-free survival rate, the median disease-free survival time, tumor recurrence rate, cases with recurrence pattern as local recurrence, liver recurrence, other distant recurrence, local and distant recurrence were 81.7%, 39.0%, 27 months(95% confidence interval as 19?33 months), 61.0%, 34.2%, 15 months(95% confidence interval as 12?18 months), 54.9%(45/82), 12, 16, 9, 8 for the robotic group. The above indicators were 79.3%, 36.0%, 24 months(95% confidence interval as 19?31 months), 59.8%, 27.5%, 15 months(95% confidence interval as 10?20 months), 58.5% (48/82), 10, 22, 6, 10 for the open group. There was no significant difference in overall survival or disease-free survival between the two groups ( χ2=0.39, 0.47, P>0.05). There was no significant difference in tumor recurrence rate or tumor recurrence site between the two groups either ( χ2=0.22, 1.86, P>0.05). Conclusion:After the learning curve, robotic pancreato-duodenectomy has non-inferior prognosis compared with open pancreatoduodenectomy.

Objective:To explore the influence factors of neurodevelopmental disorders in children with SCN8A-related early-onset epilepsy through analyzing their clinical characteristics and following up their neurodeve-lopmental status. Methods:A retrospective analysis was carried out on 21 children (13 males and 8 females, the age ranged from 4 months to 8 years, average 31.6 months)with SCN8A-related early-onset epilepsy treated in Guangzhou Women and Children′s Medical Center and Kunming Children′s Hospital between January 2017 and February 2021.All patients underwent whole-exome sequencing and Sanger sequencing.The pathogenicity was estimated according to the American College of Medical Genetics and Genomics guidelines.The clinical data of all patients were also collected, including the age of onset of the disease, forms of seizures, seizure frequency, neurological development at onset, electroencephalogram (EEG) and brain magnetic resonance imaging (MRI). Besides, the patients were followed up to acquire the effect of sodium channel blockers after the onset of seizures, the process or improvement of neurodeve-lopment, EEG evaluation and neurodevelopmental outcomes.Patients were grouped based on data analysis results.The Fisher′s exact test was conducted to measure the effect of various factors on the neurodevelopmental process and outcome, and corresponding coe-fficients were calculated. Results:The average onset age of 21 patients was 0-9 months.The follow-up duration was 4 months-8 years.Three cases died.Sixteen cases (76.2%) had early infantile epileptic encephalopathy (EIEE), 5 cases (23.8%) had epilepsy without encephalopathy, and 1 case had benign infantile epilepsy.Fourteen cases (66.7%) belonged to drug resistant epilepsy.Only one child showed normal neurodevelopment.Eleven children showed delayed neurodevelopment, but improvement was observed.Nine children were retrogressed and stagnated in terms of neurodevelopment.Small age at onset ( Fisher=9.517, P=0.020, r=0.571), high seizure frequency ( Fisher=10.512, P=0.003, r=0.572), EEG background ( Fisher=10.512, P=0.003, r=0.572), epileptic discharges ( Fisher=8.288, P=0.008, r=0.542), and EEG changes before and after treatment ( Fisher=10.437, P=0.009, r=0.586) were important factors affecting the neurodevelopmental process.Neurodevelopmental outcome was normal in only 1 case, 1 child belonged to mild mental retardation (MR), 7 children belonged to moderate MR, 3 children belonged to severe MR, and 9 children belonged to profound MR.Statistical analysis indicated that the clinical phenotype ( Fisher=10.059, P=0.004, r=0.739) and drug resistance ( Fisher=13.706, P=0.001, r=0.640) were significantly correlated with neurodevelopmental outcomes.However, the forms of seizures, EEG findings at onset and mutation sites were not related to neurodevelopmental disorders. Conclusions:Most children with SCN8A-related early-onset epilepsy are accompanied with neurodevelopmental retardation of varying degrees.Epileptic encephalopathy and poor response to drug treatment will lead to severe neurodevelopmental disorders.

Objective:To explore the clinical characteristics and treatment of a family with inherited generalized epilepsy with febrile seizures plus (GEFS + ) caused by the KCNT2 gene mutation and review the literature. Methods:Clinical data of a child with GEFS + and his family members who visited Department of Pediatric Neurology, Guangzhou Women and Children′s Medical Center in May 2019 were collected.DNA samples were collected from the peripheral blood of the proband, his parents, his elder brother, and his maternal grandparents, and genetic analysis and verification were performed using the next-generation sequencing technique.Using " KCNT2" as the key word, literature was retrieved from PubMed, China National Knowledge Infrastructure and Wanfang databases (up to August 2019). Results:The proband was a 3-year-old boy who was admitted to Guangzhou Women and Children′s Medical Center because of frequent epileptic seizures in the past 5 months.He presented with a binocular gaze and experienced 3 to 8 times of extremities myoclonic-spastic epileptic attacks every day.He had a history of 3 times of febrile seizures at the age of 2 years old.His seizures were refractory to Sodium valproate, Topiramate, Nitrazepam and Levetiracetam.His elder brother and mother had a history of childhood febrile seizures.Other members in the family had no history of convulsion.Ictal electroencephalogram showed general 1 Hz high voltage spike-slow waves.A heterozygous nonsense mutation of KCNT2 gene c. 574C>T(p.Q192X) that was never reported previously was detected in the proband, his brother, mother and maternal grandmother.Furthermore, no other family members carried the mutation at the c. 574 locus of the KCNT2 gene.No article in Chinese was found, and 2 articles in a language other than Chinese provided the complete data of 3 sporadic cases.Together with 4 cases in the family studied in this article, there were 7 cases and 4 mutation sites in KCNT2 gene.Of these mutations, there were 3 missense mutations and 1 nonsense mutation.Three sporadic patients presented with early infantile epileptic encephalopathy.The family of this study was characterized with febrile seizures and febrile seizures plus. Conclusions:A de novo mutation and phenotype of the KCNT2 gene is found in a family with GEFS + .It would expand the gene mutation spectrum and provide basis for family genetic counseling. KCNT2 mutation induced GEFS + is refractory to antiepileptic drugs.

Objective To evaluate the correlations between the cerebral hemodynamic changes of severe acute encephalopathy with the clinical features from emergency periods to stable periods and the value of transcranial Doppler ultrasonography( TCD)in cerebral function assess. Methods Thirty patients with acute brain diseases by assisted mechanical ventilator from Jun 2014 to May 2015 in PICU were included and followed up to Nov 2015,then grouped by Glasgow Coma Scale( GCS),MRI,prognosis( mental sequelae after half a year). Each subject was examined through the temporal bone window by TCD at emergency peri-ods and stable periods. The systolic cerebral blood flow velocity( sCBFV),and pulsatility index( PI)of bilat-eral middle cerebral artery( MCA),anterior cerebral artery,posterior cerebral artery were analyzed. Multivari-ant analysis of variance,repeated measures analysis of variance was conducted to compare sCBFV and PI of MCA among groups in different clinical periods. The variants included sex,disease diagnosis,prognosis, MRI,GCS,and the first abnormal TCD. The variation within groups was tested via a Hotelling T2 test. All sCBFV and PI of each artery and the D-value of sCBFV between the different periods were compared accord-ing to the prognosis groups. Results (1)Five patients could be lateralized,and their lateralization of MRI focus was consistent with the abnormal sides of sCBFV in the stable periods.(2)The D-value of sCBFV in left MCA between the different periods in the poor prognosis group was significantly higher than that in the good prognosis group[(71. 93 ± 58. 21)cm/s vs.(33. 20 ± 30. 23)cm/s,t = -2. 287,P =0. 033].(3) Multivariant analysis of variance showed that GCS classification and disease diagnosis were significantly cor-related with the cerebral hemodynamic changes respectively(P =0. 042,0. 005,respectively).(4)sCBFV and PI of left MCA reduced significantly in the stable periods than those in the emergency periods( P =0. 002,0. 003,respectivly). Conclusion The cerebral hemodynamic changes by TCD from emergency peri-ods to stable periods are consistent with the clinical status,dynamic evaluation by TCD may facilitate the evaluation of brain dysfunction in the severe acute encephalopathy.
