Objective:To investigate the relationship between heart rate variability(HRV), deceleration capacity(DC) and cardiovascular metabolic disease(CMD) in children and adolescents with normal weight obesity(NWO).Methods:A total of 200 children and adolescents aged 6-17 who underwent normal physical examination in Chengdu Women′s and Children′s Central Hospital from December 2022 to June 2023 were included in this retrospective case-control study.They were divided into the NWO group, normal weight lean(NWL) group, and overweight-obesity(OW-OB) group according to their body mass index(BMI) and body fat percentage(BF%).Fifty children were enrolled into the NWO group; fifty-one children were enrolled into the NWL group; and 99 children were enrolled into the OW-OB group.All the subjects received 24-hour heart monitoring, and their HRV indexes, such as the standard deviation of N-N interval in normal sinus(SDNN), the standard deviation of the mean value N-N intervals every 5-minute(SDANN), the mean of the standard deviations of all N-N intervals for each 5-minute segment of 24 hours(SDNNindex), the root mean square of successive N-N interval difference(rMSSD), the proportion of N-N 50(the successive N-N interval differences>50 ms) in the total number of N-N intervals(pNN50), and DC were automatically calculated.Blood pressure, fasting blood glucose and blood lipids were measured, and the cardiometabolic risk score(CRS) was obtained through the accumulation of relevant factors.The general data, SDNN, SDANN, SDNNindex, rMSSD, pNN50, DC and CRS of the three groups were compared by variance analysis.Spearman correlation and multivariate Logistic regression were used to analyze the risk factors affecting CRS.Results:There was no significant difference in age, gender and other general information among the three groups(all P>0.05).SDNN in the NWO, NWL, and OW-OB groups were(120.88±16.36) ms, (129.07±16.36) ms, and(109.29±16.38) ms, respectively( F=26.231, P<0.001); SDANN were(64.44±11.61) ms, (66.25±8.34) ms, and(61.70±6.85) ms, respectively( F=5.048, P=0.007); rMSSD were(27.02±3.87) ms, (27.51±5.92) ms, and(25.12±6.78) ms, respectively( F=3.328, P=0.038); pNN50 were(12.62±4.04)%, (13.39±2.26)%, and(11.22±2.93)%, respectively( F=9.099, P<0.001); DC were(4.83±0.20) ms, (4.94±0.33) ms, and(4.63±0.28) ms, respectively( F=23.496, P<0.001)and CRS was 0.94±0.87, 0.69±0.19 and 1.57±1.07, respectively( P<0.01).The differences between the three groups were statistically significant.Spearman correlation analysis showed that BMI( r=0.211, P=0.003) and BF%( r=0.558, P<0.001) were significantly positively correlated with CRS, while SDNN( r=-0.258, P<0.001) and DC( r=-0.499, P<0.001) were significantly negatively correlated with CRS.Multivariate Logistic regression analysis showed that BF%(95% CI: 0.098-0.265, P<0.001) and DC(95% CI: -3.962--1.391, P<0.001) were independent risk factors for predicting CMD. Conclusions:Increased BF% and decreased DC are independent risk factors for CMD.Analysis of body composition and HRV in children and adolescents can help to identify potentially high-risk groups more accurately, intervene early, and reduce the risk of CMD.

Nanomaterial matrices have unique advantages in small molecule analysis by matrix-assisted laser desorption ionization mass spectrometry(MALDI-MS).On the basis of comparing different surfactants,a method for pre-coating nanocarbon sodium dodecyl sulfate(SDS)composite matrix was established,which could alleviate the issue of aggregation of nanocarbon particles as a matrix.The experimental results showed that the nanocarbon-SDS composite pre-coated matrix effectively suppressed the background ion peak of the nano matrix,significantly improved the MS peak intensity and signal-to-noise ratio of the tested substance.Under the optimal conditions,cholesterol,1,2-dipalmitoyl-sn-glyceryl-3-phosphorylcholine(DPPC),and triglyceride standards were analyzed,with intra-point repeatability(RSD)of MS peak intensity≤5%and inter-point repeatability≤7%.As to measurement of cyclic adenosine monophosphate and DPPC samples in the range of 0.05?1.0 mg/mL,linear correlation coefficient(R2)between peak intensity and concentration was greater than 0.993,indicating good quantitative analysis potential.The nanocarbon-SDS composite pre-coating matrix was used for MALDI-MS imaging of pig brain tissue,and the differences in component distribution between pig brain white matter and gray matter were observed,demonstrating the potential of nanocarbon-SDS composite pre-coating matrix for MALDI-MS imaging.

Objective To explore the influence factors and predictors of treatment response after adrenocorticotropic hormone(ACTH)in infantile epileptic spasms syndrome(IESS).Methods A retrospective analysis was conducted on 80 cases of IESS infants(50 males and 30 females)who were diagnosed and treated with ACTH in Chengdu Women's and Children's Central Hospital from January 2016 to December 2020.Patients were divided into effective group(n=39)and ineffective group(n=41)based on their response of ACTH treatment after 28 days,and their clinical data including the patients'basic information,etiology,treatment programmer,per-and post-treatment Kramer scores of electroencephalogram(EEG)hypsarrhythmia severity and so on,were collected to compare and analyze between the two groups.A modified Poisson regression model was constructed to discover predictors of outcome,and the receiver operating characteristic(ROC)curves were used to assess the prognosis evaluation of the positive predictive value.Results The ages at seizure onset ranged from one month and seven days to one year and nine months.Seizure types included simple epileptic spasms in 66 cases and combined with other types(focal and secondarily generalized seizures)in 14 cases.Thirty-two cases had been given anti-seizure medications(ASMs)before ACTH treatment.The median Kramer scores per-treatment and at 14 days post-treatment were 10.0(8.3,12.0)and 6.0(4.0,7.0),respectively.After ACTH treatment,39(48.8%)cases were effective.Compared with the effective group,the ineffective group had significantly higher proportion of abnormal perinatal conditions,unknown aetiology with normal development,ASMs given before ACTH treatment,the dosages of ACTH greater than 2 U/(kg·d),combinations of two or more ASMs,poor control,and still seizure attack after ACTH treatment of 14 days(P<0.05).Additionally,the Kramer scores after ACTH treatment of 14 days in the ineffective group were also significantly higher(P<0.05).The modified Poisson regression model showed that there were significant statistic differences between the two groups on ASMs given before ACTH treatment(RR=0.546,95%CI 0.357-0.833,P=0.005)and Kramer scores of hypsarrhythmia severity(RR=0.701,95%CI 0.620-0.792,P<0.001),while there were no significant differences between the two groups in term of ages,gender,perinatal conditions,etiologies,seizure types,Kramer scores before treatment,time lag between onset and treatment,duration of ACTH treatment,kinds of ASMs combination.ROC curve analysis showed that only Kramer scores at 14 days after ACTH treatment could predict the treatment response with sensitivity and specificity of 92.7%and 84.6%,respectively,with Youden index of 0.773.The area under the ROC curve was 0.930(95%CI 0.873-0.987,P<0.001)and the cut-point of the score was 6,indicating that the higher the Kramer scores at 14 days after ACTH treatment,the worse the treatment response.The treatment response rate would reduce by about 30.0%if the Kramer score increased by one point.Conclusion ASMs given before ACTH treatment may influence the treatment response.Kramer scores greater than 6 at day 14 after ACTH treatment may be used as a predictor of treatment response after ACTH in IESS patients.

Objective To explore clinical effect of closed reduction percutaneous elastic intramedullary nail assisted by arthrography in the treatment of radial neck fracture in children.Methods A retrospective analysis was performed on 23 chil-dren with radial neck fracture treated with arthrography assisted closed reduction and percutaneous elastic intramedullary nail internal fixation(arthrography with elastic nail group)from January 2019 to December 2022,including 12 males and 11 fe-males,aged from 2 to 12 years old with an average of(7.36±1.89)years old;According to Judet fracture types,14 children were type Ⅲ and 9 children were type Ⅳ.In addition,23 children with radial neck fracture were selected from January 2015 to December 2018 who were treated with closed reduction and percutaneous elastic intramedullary nail fixation(elastic nail group),including 11 males and 12 females,aged from 2 to 14 years old with an average of(7.50±1.91)years old;Judet classi-fication included 15 children were type Ⅲ and 8 children were type Ⅳ.Operative time and intraoperative fluoroscopy times were compared between two groups.Metaizeau evaluation criteria was used to evaluate fracture reduction,and Tibone-Stoltz evaluation criteria was used to evaluate functional recovery of elbow between two groups.Results Both groups were followed up for 12 to 24 months with an average of(16.56±6.34)months.Operative time and intraoperative fluoroscopy times of elastic nail group were(56.64±19.27)min and(21.13±7.87)times,while those of joint angiography with elastic nail group were(40.33±1 1.50)min and(12.10±3.52)times;there were difference between two groups(P＜0.05).According to Metaizeau evaluation,11 patients got excellent result,9 good and 3 fair in joint angiography with elastic nail group,while in elastic nail group,5 ex-cellent,13 good,4 acceptable,and 1 poor;the difference between two groups was statistically significant(P＜0.05).According to Tibone-Stoltz criteria,14 patients got excellent result,8 good,and 1 fair in joint arthrography with elastic nail group;while in elastic nail group,12 patients got excellent result,9 good,1 fair and 1 poor;there was no significant difference between two groups(P＞0.05).Conclusion Compared to percutaneous elastic intramedullary nail fixation,closed reduction assisted by arthrography has advantages of reduced operation time,decreased intraoperative fluoroscopy frequency,and improved fracture reduction.Arthrography enables clear visualization of the anatomical structures of radius,head,neck,bone,and cartilage in children,facilitating comprehensive display of fracture reduction and brachioradial joint alignment.This technique more pre-cisely guides the depth of elastic intramedullary nail implantation in radius neck,thereby enhancing surgical efficiency and success rate.

Objective:To evaluate the efficacy and safety of traditional Chinese medicine(TCM)in the treatment of male im-mune infertility(MII)by meta-analysis.Methods:We retrieved randomized controlled trial(RCT)on the treatment of male im-mune infertility with traditional Chinese medicine from the databases of WanFang,Chinese Biomedical Literature,Cochrane Library,Weipu,PubMed and CNKI,and performed methodological quality assessment of the RCTs identified and statistical analysis and evalua-tion of the publication bias using the RevMan5.4 software.Results:Totally,25 RCTs(2 563 cases)were included in this study.Compared with Western medicine alone in the treatment of MII,TCM achieved a significantly higher total effectiveness rate(OR=6.35,95% CI:4.96-8.13,P<0.000 01),negative conversion rate of seminal plasma anti-sperm antibodies(OR=4.52,95% CI:2.72-7.51,P<0.000 01),negative rate of serum anti-sperm antibodies(OR=2.98,95% CI:2.23-3.96,P<0.000 01),sperm concentration(MD=15.56,95% CI:11.32-19.79,P<0.000 01),grade a sperm motility(MD=3.85,95% CI:1.91-5.79,P=0.000 01),grade a+b sperm motility(MD=13.77,95% CI:7.06-20.48,P<0.000 1),sperm viability(MD=10.32,95% CI:6.78-13.86,P<0.000 01)and pregnancy rate(OR=3.53,95% CI:2.68-4.63,P<0.000 01),but a lower rate of adverse reactions(OR=0.06,95% CI:0.01-0.23,P<0.000 01).There was no statistically significant difference in the percentage of morphologically abnormal sperm between TCM and Western medicine alone in the treatment of MII(MD=-7.53,95% CI:-15.50-0.44,P=0.06).Conclusion:TCM has a definite effectiveness and high safe in the treatment of male immune infertility.

Background: Intrahepatic cholangiocarcinoma (ICC) is a highly desmoplastic tumor with poor prognosis even after curative resection. We investigated the associations between the composition of the ICC stroma and immune cell infiltration and aimed to develop a stromal-immune signature to predict prognosis in surgically treated ICC. Patients and methods: We recruited 359 ICC patients and performed immunohistochemistry to detect α-smooth muscle actin (α-SMA), CD3, CD4, CD8, Foxp3, CD68, and CD66b. Aniline was used to stain collagen deposition. Survival analyses were performed to detect prognostic values of these markers. Recursive partitioning for a discrete-time survival tree was applied to define a stromal-immune signature with distinct prognostic value. We delineated an integrated stromal-immune signature based on immune cell subpopulations and stromal composition to distinguish subgroups with different recurrence-free survival (RFS) and overall survival (OS) time. Results: We defined four major patterns of ICC stroma composition according to the distributions of α-SMA and collagen: dormant (α-SMAlow/collagenhigh), fibrogenic (α-SMAhigh/collagenhigh), inert (α-SMAlow/collagenlow), and fibrolytic (α-SMAhigh/collagenlow). The stroma types were characterized by distinct patterns of infiltration by immune cells. We divided patients into six classes. Class I, characterized by high CD8 expression and dormant stroma, displayed the longest RFS and OS, whereas Class VI, characterized by low CD8 expression and high CD66b expression, displayed the shortest RFS and OS. The integrated stromal-immune signature was consolidated in a validation cohort. Conclusion We developed and validated a stromal-immune signature to predict prognosis in surgically treated ICC. These findings provide new insights into the stromal-immune response to ICC.
