Objective To observe the value of transesophageal echocardiography(TEE)for guiding left atrial appendage closure(LAAC)with LAmbre occluder.Methods Data of 40 non-valvular atrial fibrillation(NVAF)patients who underwent LA AC with LAmbre occluder were retrospectively analyzed.CT angiography(CTA)before treatment,TEE and digital subtraction angiography(DSA)findings during LAAC were comparatively observed,and the correlations of the anchor area diameter and left atrial appendage opening diameter measured with the above three as well as occluder size were analyzed,and TEE and DSA for evaluating peri-device leak(PDL)were compared.Results LAAC were successfully performed with LAmbre occlude in all 40 cases.The diameter of the fixed umbrella was positively correlated with anchor area diameter measured with CTA,TEE and DSA(r=0.79,0.82,0.91,all P＜0.01),of occlusion umbrella was positively correlated with left atrial appendage opening diameter measured with CTA,TEE and DSA(r=0.56,0.89,0.86,all P＜0.01).Immediately after the release of occluder in LAAC,PDL occurred in 16 cases and were detected with both TEE and DSA,while in the rest 24 cases no PDL was found with neither TEE nor DSA.Conclusion TEE had comparable value to DSA for guiding LAAC using LAmbre occluder.

Pregnant women account for 40% of all epilepsy patients, and the economic burden of pregnant women with epilepsy is 5 times higher than that of non-pregnant patients. Additionally, the rates of stillbirth and congenital malformations in pregnant women with epilepsy are 5 times greater than those in normal pregnant women. Therefore, it is crucial to comprehensively review and summarize the management of pregnant women with epilepsy to reduce the burden of the disease. This study provides a thorough review on teratogenic effects of anti-seizure medications (ASMs) used during pregnancy, and summarizes the effects of ASMs on health of offspring and offers clinical management recommendations for pregnant women with epilepsy, aiming to provide guidance for safe use of medications during pregnancy.

Objective:To investigate the correlation between complement C3 and urine protein level and proteinuria remission status in patients with primary membranous nephropathy (PMN), and better guide individualized clinical treatment.Methods:It was a single-center retrospective study. The clinical data of PMN patients who underwent renal biopsy in the First Affiliated Hospital of Nanjing Medical University from January 2017 to June 2022 were collected. Patients with 24 h urinary protein ≥ 3.5 g were followed up after receiving standard treatment, and the last outpatient or inpatient review was used as the end point of follow-up. 24 h urine protein was collected to evaluate the remission status of proteinuria. Kaplan-Meier method was used to analyze the correlation between serum and renal complements and proteinuria remission. Cox regression analysis method was used to analyze the correlation between serum C3 level and renal tissue C3 deposition and proteinuria remission.Results:This study included 507 PMN patients with 312 (61.54%) males, aged 54 (43, 64) years old. Compared with 24 h urinary protein < 3.5 g group, proportion of males ( χ2=22.479, P<0.001), age ( Z=-2.521, P=0.012), systolic blood pressure ( Z=-4.148, P<0.001), diastolic blood pressure ( Z=-4.084, P<0.001), serum anti-phospholipase A2 receptor (PLA2R) antibody titer ( Z=-7.019, P<0.001), total cholesterol ( Z=-8.796, P<0.001), triglyceride ( Z=-6.158, P<0.001), low density lipoprotein cholesterol ( Z=-8.716, P<0.001), serum creatinine ( Z=-7.368, P<0.001), serum C3 ( Z=-3.663, P<0.001), serum C4 ( Z=-6.560, P<0.001), proportion of glucocorticoid use ( χ2=116.417, P<0.001) and proportion of immunosuppressant use ( χ2=53.839, P<0.001) were all higher, while serum albumin ( Z=12.518, P<0.001), estimated glomerular filtration rate ( Z=6.345, P<0.001) and serum IgG ( Z=7.321, P<0.001) were all lower in 24 h urinary protein ≥3.5 g group. There were 268 patients included in the follow-up cohort with baseline 24 h urinary protein of 7.15 (5.14, 10.24) g, serum anti-PLA2R antibody titer of 61.44 (14.35, 193.24) RU/ml, serum C3 of 1.005 (0.864, 1.150) g/L, and serum C4 of 0.260 (0.214, 0.317) g/L. Kaplan-Meier survival curve showed that the incomplete remission rate of proteinuria in serum C3 > 1.005 g/L group was lower than that in serum C3 ≤ 1.005 g/L group (log-rank χ2=4.757, P=0.029). There was no significant difference in the incomplete remission rate of proteinuria between serum C4 ≤ 0.260 g/L group and serum C4 > 0.260 g/L group (log-rank χ2=3.543, P=0.060). Renal C1q (log-rank χ2=0.167, P=0.683) and C4 (log-rank χ2=1.927, P=0.165) deposition had no significant effects on proteinuria remission in PMN patients. The incomplete remission rate of proteinuria in patients with renal C3 deposition was higher than that in patients without renal C3 deposition (log-rank χ2=7.018, P=0.008). Univariate Cox regression analysis showed that serum C3 level and C3 deposition in renal tissues were influencing factors of incomplete remission of proteinuria (both P<0.05), while adjusting for gender, age, mean arterial pressure, serum anti-PLA2R antibody, serum albumin and 24 h urinary protein, serum C3 ≤ 1.005 g/L ( HR=1.374, 95% CI 1.021-1.849, P=0.036), C3 deposition in renal tissues ( HR=1.949, 95% CI 1.098-3.460, P=0.023), and serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues ( HR=1.472, 95% CI 1.093-1.983, P=0.011) were independent influencing factors of incomplete remission of proteinuria. Conclusions:The serum C3 level and C3 deposition in renal tissues are closely related to urinary protein level and proteinuria remission status in PMN patients. The patients with higher urinary protein have higher serum C3. For patients with massive proteinuria, serum C3 ≤ 1.005 g/L, C3 deposition in renal tissues, serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues are independent risk factors of incomplete remission of proteinuria.

For the treatment of postherpetic neuralgia, drugs have always played a major but unsatisfactory role. As auxiliary or alternative therapies for postherpetic neuralgia, non-pharmacological interventions, such as electrical stimulation and repetitive transcranial magnetic stimulation, not only have shown favorable efficacy, but also can decrease adverse reactions to drugs with high safety and patient acceptance, and are benificial for management of patients with postherpetic neuralgia.

Objective: The study aimed to explore sex differences in the growth and physical development of Beijing school-aged children and adolescents. Methods: Data obtained from regular health examinations of 94 122 school-aged children and adolescents aged 6-18 years old were collected from primary and high schools in Shunyi District from 2009 to 2018, and a longitudinal dataset was compiled with complete anthropometric parameters including height, weight, and BMI levels after linkage of individuallevel information. The age-specific growth rate was calculated and a linear mixed-effects model was used to identify sex differences according to chronological or relative age to peak height velocity (PHA). Results: Height, weight, and BMI levels increased with age in both boys and girls. Girls were taller than boys in the 10-11 year-old age group, catch-up growth in height was observed in boys at age 12, whose height surpassed that of girls thereafter. Boys had a higher weight and BMI than girls in all age groups (P<0.01). Sex differences were found in the growth rates of height, weight, and BMI levels(t=-67.56，-47.46，3.22，P<0.01), which was demonstrated by the interaction effect of sex and age in the linear mixed-effects model. The PHA in boys was 12 years old, which was two years later than the PHA in girls. Boys reached peak weight velocity at 12 years old, lagging one year behind girls who reached their peak at 11 years old. The curves of the BMI growth rate with age showed double peaks in boys and the first peak appeared at 10 years, which was one year earlier than girls. The change in weight was highly synchronized in time with the increase in height, after adjusting for the growth rate of weight by PHA. Weight velocity increased with age before the onset of puberty until PHA, and then it declined; boys presented with obvious fat accumulation before the onset of puberty. Conclusion Sex differences in the growth and physical development of school-aged children and adolescents were persistent and apparent, and the change in weight was highly synchronized in time with the increase in height.

Objective: To explore sex differences between weight and systolic blood pressure (SBP) changes among school-age children and adolescents in Beijing, and to provide a basis for priority intervention to control the rapid growth of body weight and blood pressure. Methods: Anthropometric measurement data of 70 288 children and adolescents from primary and high schools in Shunyi District were collected from 2009 to 2018, and a longitudinal dataset with complete data related to weight and BP after individual data linkage was compiled. The age-specific weight and SBP growth rates were calculated, and a linear mixed-effects model was used to identify sex differences in chronological growth rates. Results: Weight and SBP increased with age in both boys and girls, and the mean weight and SBP were higher in boys than in girls across all age groups. The result of the linear mixed-effects model indicated apparent sex differences in weight and SBP growth rates, with an age and sex interaction term(β=-0.35, -0.40, P<0.01). The age at peak weight velocity (PWA) was 12 years old and the age at peak SBP velocity was 13 years old in boys, which occurred one and three years later than for girls, respectively. In addition, the peak weight and SBP velocity were higher in boys than in girls. The curves of the SBP growth rate adjusted for the PWA, showed that the peak SBP velocity occurred two years before PWA and the second peak SBP velocity occurred at the PWA, which indicated "double peaks" in both boys and girls. The SBP growth rate was always higher in boys than in girls, and the rates declined after PWA. Conclusion Sex differences in weight and SBP growth rates were persistent and obvious in school-age children and adolescents in Beijing and the change in SBP was highly time synchronized with the increase in weight.

Objective: To explore differences in the detection rate of elevated blood pressure (BP) in children aged 6-8 years old, and to verify the apparent existence of white-coat hypertension (BP) in children. Methods: Based on census data(PROC), and three subsequent BP readings were taken during follow-ups which were carried out from October 2018 to June 2019. A total of 1 785 children were included in the present study. Using updating blood pressure reference for Chinese children aged 3-17 years, compared the BP detection rate at baseline, at the first follow-up, and the average value of the last two BP readings. Fluctuations in the detection rate of elevated BP in children at different time-points were analyzed. Results: The detection rates of the three elevated BP measurements of 6-8-year-old children were 57.65%, 25.88% and 15.46%, respectively, and the detection rate was higher among boys than girls. The detection rate of baseline BP was higher than that of the first follow-up BP measurements and the average of the last two BP measurements(P<0.01). Given the agreement in the diagnosis of high SBP, high DBP, high BP at baseline, and the average of the last two follow-up BP measurements, elevated BP at baseline was the lowest among the three groups and SBP was higher than DBP. Conclusion Blood Pressure fluctuations might be caused by transient tension that was experienced during the baseline BP measurement and during the first of the three follow-ups. Therefore, the average value of last two BP measurements may better reflect the real BP level in children.

Objective: To examine the association between the visceral adiposity index (VAI) and nonalcoholic fatty liver disease (NAFLD) in the pediatric population in order to improve risk stratification and prevention systems for chronic liver disease. Methods: A total of 510 overweight/obese children aged 6-8 years old were enrolled from the child cohort which was designed to study puberty, obesity, and cardiovascular risk (PROC), and complete data from liver ultrasounds and the VAI were obtained. Used Spearman s rank correlation coefficient, Chi-square tests, and Logistic regression analyses to explore the association between the VAI and NAFLD. Results: The detection rates of NAFLD for boys and girls were 25.9% and 11.1%, respectively. VAI for normal group and the NAFLD group were 0.43(0.31, 0.61) and 0.61(0.44, 0.87) in boys, and 0.74(0.56, 1.07) and 1.08(0.67, 1.51) in girls, respectively. Spearman s correlation coefficient analysis showed that triglycerides(TG), VAI, and the third quintile VAI group were positively correlated with NAFLD in both boys and girls(r=0.19,0.26,0.29;0.16,0.16,1.18,P<0.05), and high-density lipoprotein-cholesterol (HDL-C) was negatively correlated with NAFLD in boys (r=-0.21, P<0.05). With advancing tertiles of VAI, the increasing trend in the NAFLD detection rate was statistically significant in boys and girls(Chi-square for trend were 21.77,7.66, P<0.01). The results of univariate and multivariable Logistic regression showed that, by taking the first tertile of VAI as a reference, the risk of NAFLD among boys was higher in the second tertile (cOR=2.59, 95%CI=1.15-5.86; aOR=2.33, 95%CI=1.01-5.36) and in the third tertile(cOR=5.73, 95%CI=2.62-12.53; aOR=4.87, 95%CI=2.15-11.03), where as the risk among girls was higher in the third tertile(cOR=4.43, 95%CI=1.40-14.00). Conclusion VAI is positively correlated with pediatric NAFLD. Higher tertiles of VAI were associated with an increased risk of NAFLD in overweight and obese children, which indicates that VAI can be used as an early predictor of NAFLD.

Objective: To identify the association of carotid intima-media thickness (cIMT) and visceral fat area (VFA) to inform prevention of cardiovascular disease in later life. Methods: All the grade one students of six non-boarding primary schools in Shunyi District, Beijing were enrolled, based on population-based survey design, to establish the child cohort on sensitization, puberty, obesity and cardiovascular risk (PROC). Socio-demographic information survey and anthropometric measure, blood and urine test were carried out. Robust linear regression was used to determine the relationship between cIMT and other factors. Results: Among 1 711 participants, a significant difference were observed between normal, overweight and obesity children on cIMT [(0.35±0.02)(0.36±0.02)(0.37±0.03)mm] (F=41.4, P<0.01) and VFA [16.2(13.6-19.3), 22.7(18.6-27.3), 51.5(33.9-73.0)cm2] (χ2=854.5, P<0.01). After adjusting age and sex, univariate robust linear regression showed that cIMT was associated with height, SBP, DBP, HDL-C, VFA (P<0.05) and TG (P=0.055). Multivariable robust linear regression indicated that in total and boys only included models, cIMT was associated with VFA and SBP(β=0.000 2, 0.000 2, 0.000 2, 0.000 2, P<0.05); while in girls only included model cIMT was associated with VFA and TG (β=0.000 2, 0.006 2, P<0.05). Conclusion VFA is stable to predict the increase of cIMT in children. We can use VFA to simplify the classification management of children and inform targeted early prevention of cardiovascular disease in adulthood.

Objective:To explore sex difference in height growth and blood pressure (BP) change among Beijing school-age children and adolescents.Methods:Using physical examination data of 70 769 school-age children and adolescents from primary to high school during 2009-2018 in Shunyi District, a longitudinal dataset was formed with completed anthropometrical measurements of height and blood pressure (BP) after individual information linkage. Age-specific height, BP, growth rate of height and BP as well BP growth rate based on age at peak height velocity (PHA) were calculated. Linear mixed-effects model was used to identify sex disparity in the growth rates of height and BP.Results:Height and BP increased with age in both boys and girls, and the mean height and BP of boys were always higher than those of girls, except age group from 10 to 11 years. Sex disparity existed in growth rates of height and BP ( P<0.001), which was demonstrated by the interaction item of"sex ?×?age"in linear mixed-effects model. The PHA of boys was 12 years old, which was 2 years later than that of girls, about 10 years old. The curves of BP growth rate with age showed double peaks in both boys and girls. Boys reached the peak BP velocity at 13 years old, 3 years lagging behind that of girls who reached the peak at 10 years old. However, the peak of height and BP velocity of boys were higher than that of girls. The change of BP was highly synchronized in time with the increase of height, after adjusting for the growth rate of height by PHA. BP velocity increased with age before onset of puberty till PHA and then declined. Conclusion:Sex disparity in height growth and BP change among school-age children and adolescents is persistent and significant and the change of BP is highly synchronized in time with the increase of height.
