Objective:To analyze the effects of biodegradable-polymer sirolimus-eluting stents (BP-SES) and durable polymer sirolimus-eluting stents (DP-SES) implantation on serum endothelin 1 levels and the incidence of coronary restenosis in patients with coronary heart disease (CHD).Methods:A total of 114 patients with CHD admitted to the First People's Hospital of Xianyang in Shaanxi Province from May 2022 to January 2024 were selected. According to the principle of comparable baseline characteristics between groups, patients were divided into two groups by random number table method, with 57 cases in each group. After pretreatment of diseased vessels, DP-SES group underwent implantation of DP-SES with appropriate length and diameter, while BP-SES group underwent implantation of BP-SES with appropriate length and diameter. After implantation, non-compliant balloons were used for in-stent post-dilation. Comparisons of vascular endothelial function, levels of inflammatory factors and hemodynamic indicators before operation and at 6 months between groups were made postoperatively, also, the incidence rates of major adverse cardiovascular events (MACE) and coronary restenosis within 6 months were also compared. Measurement data with normal distribution was expressed as “xˉ±s”, independent sample t-test was used on comparison between groups, paired t-test was used for intra-group comparisons before and after treatment. Counting data was expressed as rate or composition ratio, χ2 test was used on comparison between groups. Results:At 6 months after surgery, the levels of endothelin 1 and VEGF were lower in BP-SES group compared to DP-SES group,[(72±5) ng/L vs. (77±7) ng/L, (147±25) ng/L vs. (157±27) ng/L, t=3.76, P<0.001, t=2.16, P=0.033]. The level of nitric oxide was higher in BP-SES group compared to DP-SES group [(79±7) μmol/L vs. (76±8) μmol/L, t=2.46, P<0.001]. At 6 months after surgery, the levels of TNF-α, IL-1 and CRP in DP-SES group were higher than those before surgery, and were all higher compared to BP-SES group[(81±5) ng/L vs. (75±5) ng/L, (159±18) ng/L vs. (151±16) ng/L, (31±4) mg/L vs. (29±3) mg/L, t=6.87, P<0.001, t=2.24, P=0.027, t=2.51, P=0.014]. At 6 months after surgery, the level of whole blood viscosity and plasma viscosity in both group were lower than those before surgery, and the level of Hct in BP-SES group was lower than those before surgery, the differences were statistically significant ( P<0.001), while the differences between groups were not statistically significant( P>0.05). The difference of incidence rates of MACE and coronary restenosis within 6 months between groups before surgery and 6 months after surgery were not statistically significant [7.0%(4/57) vs. 12.3%(7/57), χ2=0.91, P=0.341; 3.7%(2/57) vs. 8.3%(5/57), χ2=0.61, P=0.443]. Conclusion:Both BP-SES implantation and DP-SES implantation could effectively restore coronary blood supply, and are highly safe. However, the former can reduce damage to vascular wall and better improve endothelial function in patients.

As a novel form of cell death, ferroptosis is mainly regulated by the accumulation of soluble iron ions in the cytoplasm and the production of lipid peroxides and is closely associated with several diseases, including acute kidney injury, ischemic reperfusion injury, neurodegenerative diseases, and cancer. The term "immunosuppression" refers to various factors that can directly harm immune cells' structure and function and affect the synthesis, release, and biological activity of immune molecules, leading to the insufficient response of the immune system to antigen production, failure to successfully resist the invasion of foreign pathogens, and even organ damage and metabolic disorders. An immunosuppressive phase commonly occurs in the progression of many ferroptosis-related diseases, and ferroptosis can directly inhibit immune cell function. However, the relationship between ferroptosis and immunosuppression has not yet been published due to their complicated interactions in various diseases. Therefore, this review deeply discusses the contribution of ferroptosis to immunosuppression in specific cases. In addition to offering new therapeutic targets for ferroptosis-related diseases, the findings will help clarify the issues on how ferroptosis contributes to immunosuppression.

Objective:To analyze differences in the expression of routine laboratory parameters and cerebrospinal fluid (CSF) examination indicators between patients with non-neurosyphilis (syphilis without nervous system involvement) and those with neurosyphilis, to screen for key predictive factors, and to construct a predictive model for neurosyphilis.Methods:A retrospective analysis was conducted on the clinical data from patients with syphilis at the Fifth People's Hospital of Suzhou from 2019 to 2024. Patients with neurosyphilis and non-neurosyphilis who were hospitalized from November 2019 to June 2022 were included in the model cohort, and those hospitalized from January 2024 to October 2024 were included in the validation cohort. The patients' basic information and laboratory test indicators (including routine blood tests, CSF biochemical analysis, and syphilitic antibody tests) were collected. Statistical analysis was performed using the GraphPad software. The receiver operating characteristic (ROC) curve and the binary logistic regression method were used to analyze the predictive performance of key indicators in patients from the model cohort with SPSS software, and a predictive model for neurosyphilis was constructed. The performance of the neurosyphilis predictive model for neurosyphilis was validated based on relevant indicators from the validation cohort.Results:The model cohort included 99 patients with non-neurosyphilis (including 49 males and 50 females), and they were aged between 19 and 85 years, with an average age of 47 years; 69 patients with neurosyphilis were also included in the model cohort, including 58 males and 11 females, and they were aged between 26 and 73 years, with an average age of 51 years. The neurosyphilis group showed a significant increase in the median levels of CSF adenosine deaminase (1 U/L) and microprotein (711 mg/L), white blood cell counts (0.009 × 10?/L), as well as in the proportion of positive Pandy tests (35/69, 50.7%) compared with the non-neurosyphilis group (0 U/L, 309 mg/L, 0.002 × 10?/L, 2 /99 [2.0%], respectively, all P < 0.001). Based on the ROC curve analysis, the CSF microprotein and white blood cell count had relatively high discriminative ability (area under the ROC curve [AUC] > 0.85), while adenosine deaminase and the Pandy test showed moderate discriminative ability (0.7 < AUC < 0.85). According to the above four indicators, the logistic regression analysis showed that CSF microprotein combined with CSF white blood cell counts could construct the best predictive model for neurosyphilis, with a prediction accuracy rate of 0.980, a sensitivity of 98.5%, and a specificity of 89.9%. The prediction formula was logit (p) = -9.926 + 0.015 × microprotein + 362.33 × CSF white blood cell count, with a cutoff value of ≥ -0.867. The validation cohort enrolled 72 patients with non-neurosyphilis and 51 with neurosyphilis, and there were significant differences in CSF microprotein levels and white blood cell counts between the two groups (both P < 0.001). In the validation cohort, the predictive model demonstrated an accuracy of 86.2%, with a sensitivity of 83.6% and a specificity of 91.1% for predicting neurosyphilis. Conclusion:The predictive model for neurosyphilis constructed by combining CSF microprotein and CSF white blood cell count may contribute to the early differential diagnosis of neurosyphilis.

Objective:The clinical symptoms of children with global developmental delay (GDD) were analyzed to provide the scientific basis for the intervention of children with GDD.Methods:The results of the neuro-psychobehavioral scale were collected from 32 511 children with GDD from June 2020 to November 2023. Inclusion criteria: Children diagnosed with GDD according to the Diagnostic and Statistical Manual of Mental Disorders-V, ages 0.0 to 4.9 years. Exclusion criteria: children with common hearing impairment and visual impairment. The Chi-square tests were used for statistical analysis.Results:There were more boys than girls with GDD in outpatient clinics (68.2% vs. 31.8%). Among the children, the proportion of developmental delay in 5, 4, 3, and 2 domains was 31.1%, 23.4%, 22.9% and 22.6% respectively. The rate of delay in 2-3 domains was lower in boys (41.9%) than in girls (53.1%). The rate of delay in 4-5 domains was higher in boys (58.1%) than in girls (46.9%) ( χ2=352.11, P<0.001). Overall, outpatient GDD decreased with age. From 1.0-1.9 to 4.0-4.9 years of age, the proportion of children with developmental delay in 5 domains increased with age (18.2%, 36.4%, 43.9%, 52.4%). Among children aged 0.0-0.9 years, the proportion of 2 domains of developmental delay was higher (33.4%).Among children aged 1.0-1.9 years, the proportion of 2-3 domains of developmental delay was higher (30.7%). Among children aged 2.0-, 3.0-, 4.0-4.9 years, the proportion of developmental delay in 5 domains was higher (36.4%, 43.9%, 52.4%). In children with GDD, the fine motor delay occurred most frequently (85.1%), followed by social self-care (83.9%), language (79.0%), adaptation (62.3%), and gross motor (52.8%). The frequency of developmental delays in fine motor, adaptability, language, and social self-care in boys was higher than that in girls ( χ2=161.37, χ2=41.10, χ2=320.90, χ2=238.54, all P<0.001). The age groups with the highest delay incidence of gross motor, fine motor, adaptability, language, and social self-care were: 4.0-4.9 years (70.6%), 3.0-3.9 years (97.4%), 4.0-4.9 years (81.2%), 2.0-2.9 years (90.9%),2.0-2.9 years (95.4%). The proportions of fine motor delay in GDD children aged 0.0-0.9, 3.0-3.9 and 4.0-4.9 years were (74.5%, 97.4%, 96.8%) and the proportions of social self-care delay in GDD children aged 1.0- and 2.0-2.9 years were (92.1%, 95.4%). Peripheral and mild developmental delays were predominant in children with GDD. The proportion of severe language delay (6.4%) was higher than that in other fields. Conclusions:The proportion of GDD children with developmental delay in 4-5 domains was 54.5%. The most frequent domain of delay was fine motor. The frequencies of developmental delays in fine motor skills, adaptability, language, and social self-care in boys were higher than in girls. Most of the developmental delays in GDD children were marginal and mild. The rate of severe developmental delay in language was higher than in other domains.

Conclusion:Both BP-SES implantation and DP-SES implantation could effectively restore coronary blood supply, and are highly safe. However, the former can reduce damage to vascular wall and better improve endothelial function in patients.

Objective:To understand the identification value of pointing gestures in children with autism spectrum disorder(ASD) and its relationship with functional development.Methods:From December 2020 to November 2021, 1 099 children from Children’s Health Care Center of Beijing Children’s Hospital were tested by pointing gestures test, including 942 ASD children and 157 typical developed children.And the data of children's neuropsychological development scale from 800 children aged 1.0-5.9 were collected.SPSS 20.0 was used for statistical analysis. Trend test was used to analyze the distribution of pointing gestures test sensitivity in autistic children, and ANOVA was used to analyze the relationship between pointing gestures test scores and functional development fields.Results:The sensitivity of pointing gestures was 83.5% in children aged 1.0-10.0 years, 76.3%-93.1% in children aged 1.0-4.9 years, and 93.1%-95.1% in children aged 1.0-2.9.With the increase of age, the sensitivity of pointing gestures in autistic children (linear-by-linear association =164.889, P<0.001) and the Yoden index had a decreasing trend. The positive predictive value (91.53%-100.00%) and negative predictive value (75.36%-91.84%) were found in the children aged 1.0-10.0 years.The sensitivity of pointing gestures test was 44.9% in children with mild autism aged 1.0-10.0 years and 46.5%-65.9% in children with mild autism aged from 1.0-3.9 years. The sensitivity of pointing gestures test was 81.5% in children with moderate autism aged from 1.0-10.0 years and 87.3%-97.8% in children with moderate autism aged 1.0-3.9 years. The sensitivity of the pointing gestures test was 97.2% in children with severe autism aged 1.0-10.0 years, and 100.0% in children with severe autism aged 1.0-3.9 years. The sensitivity of the pointing gestures in mild, moderate and severe autism children decreased with age (linear-by-linear association values were 16.725, 64.232, 66.732 respectively, all P<0.001). The children with severe autism mainly scored 2 points (80.3%, 419/522) on the pointing gestures test , and children with moderate autism mainly scored 1 point(64.2%, 170/265) on the pointing gestures test. There were significant differences in functional development among different pointing gestures test groups.Functional development score in the autism children with 0 score of pointing gestures test was significantly higher than those with 1 score and 2 scores of pointing gestures test (all P<0.05). Conclusion:Pointing gestures has good sensitivity in children with autism (especially 1.0-4.9 years of age), and may serve as an objectively observable screening method. The better children with autism score on the pointing gestures, the better their functional development.

Objective:To investigate the correlation between social and linguistic parenting behaviors and developing capability of children with autism.Methods:From August 2020 to December 2020, the social and linguistic parenting behaviors of 302 parents of children diagnosed with autism were investigated in the outpatient department of the hospital.Meanwhile, the data of Gesell scale for children, the social life competence scale for infant and junior middle school students, the autism behavior checklist and the Cancy autism behavior scale were collected.SPSS 20.0 software was used for statistical analysis.Independent sample t test and analysis of variance were used to compare the social and linguistic parenting behaviors of different parents.Pearson correlation analysis was used to analyze the correlation between the social and linguistic parenting behaviors of parents and children's developmental ability and symptom severity. Results:There were no statistically significant differences in children's social and language development parenting behavior between father and mother ( t=1.033, P=0.303; t=-0.312, P=0.756). There were no statistically significant differences in children's social and linguistic parenting behaviors between fathers of different age groups ( F=1.425, P=0.244; F=1.127, P=0.345). Among mothers of different age groups, the social parenting behaviors of <30 years old and 30-34 years old groups were significantly better than those of 35-39 years old group ( F=3.374, P=0.019; LSD: P=0.010, P=0.006). Among fathers, the social parenting behavior( F=4.346, P=0.008; LSD: P=0.020, P=0.001) and social + linguistic parenting behavior in the graduate group and college group were significantly better than those in the high school/vocational group( F=3.965, P=0.012; LSD: P=0.020, P=0.002). Among mothers, the social parenting behavior ( F=2.812, P=0.040; LSD: P=0.008, P=0.023, P=0.009), linguistic parenting behavior ( F=3.769, P=0.011; LSD: P=0.010, P=0.025, P=0.001), social + linguistic parenting behavior ( F=3.654, P=0.013; LSD: P=0.005, P=0.015, P=0.002) in graduate and above groups were significantly better than those in college group, high school/vocational group, junior high school and below groups.The scores of social parenting behavior(40.72±6.80), linguistic parenting behavior(27.20±5.22), and social + linguistic parenting behavior(67.92±11.10) were significantly correlated with children’s fine motor(61.75±16.41)( r=0.193, P=0.001; r=0.153, P=0.009; r=0.190, P=0.001), cognition(68.28±16.83)( r=0.231, P=0.000; r=0.186, P=0.001; r=0.229, P=0.000), language(53.01±18.55) ( r=0.262, P=0.000; r=0.305, P=0.000; r=0.304, P=0.000) and social self-care(61.44±17.85) ( r=0.264, P=0.000; r=0.238, P=0.000; r=0.274, P=0.000). The scores of linguistic parenting behavior and social + linguistic parenting behavior were correlated with children's social life ability (8.65±0.89) ( r=0.142, P=0.046; r=0.140, P=0.049). There was no significant correlation between social parenting behavior, linguistic parenting behavior, social + linguistic parenting behavior and the scores of ABC scale (50.53±21.39) ( r=-0.089, P=0.336; r=-0.115, P=0.215; r=-0.107, P=0.250) and CABS scale (13.96±4.54) ( r=-0.050, P=0.490; r=-0.059, P=0.411; r=-0.058, P=0.421). Conclusions:The social and linguistic parenting behaviors are related to their age and educational level, and are significantly correlated to developing capability of children with autism, but have nothing to do with the severity of children's symptoms.

Objective:To understand the health status of children in an organization in the urban area of Beijing.Methods:From October to November 2019, 558 children aged from 0 to 13 of employees in an organization in Beijing received physical examination, including height, weight, ophthalmology and otorhinolaryngology, heart and lung examination, etc.Statistical analysis was conducted on the items related to physical status and with higher detection rate. Body mass index (BMI)≥P 85(P is the percentile compared to the standardized growth curve) was defined as overweight and BMI≥P 95 as obese. The rate and composition ratio were used to describe the relevant data of each item in children′s physical examination. The differences between different age groups and gender groups were compared with the chi-square test. Results:The items with high detection rate were overweight, obesity, rhinitis, caries, phimosis, etc. The ratio of children′s weight and height ≤P 10 were 3.4% and 2.7%, ≥P 97 were 12.0% and 7.0%respectively; the rates of overweight (BMI≥P 85) and obesity (BMI≥P 95) in children were 13.8% and 13.3% respectively, the ratio of weight ≥P 97, height ≥P 97 and BMI≥P 95all increased with age in all children and in boys (all P<0.05), the ratio of BMI≤P 5 increased with age ( P<0.05), and the ratio of body weight ≥P 75 decreased with age in boys ( P<0.05); the ratio of weight ≥P 75 in boys was significantly higher than that in girls ( P<0.05). The prevalence of rhinitis in children was 39.8%, among which the prevalence of allergic rhinitis was 14.9%.The prevalence of allergic rhinitis in the 3.0-5.9 age group of all children was significantly higher than that in 0.0-0.9 age group and 6.0-9.9 age group (both P<0.05), the prevalence of total rhinitis in the 3.0-5.9 age group of girls was significantly higher than that in 0.0-0.9 age group, 1.0-2.9 age group and 10.0-13.9 age group (all P<0.05). The prevalence of dental caries in children (excluding the group of 0.0-0.9 years old) was 26.0%, the prevalence of dental caries in the 3.0-5.9 age group of all children was significantly higher than that in 1.0-2.9 age group and 10.0-13.9 age group (both P<0.05), the prevalence of dental caries in 3.0-5.9 age group and 6.0-9.9 age group of boys and girls were both significantly higher than that in 1.0-2.9 age group (all P<0.05). The prevalence of phimosis in boyswas 31.5%, the phimosis rates were significantly higher in the 1.0-2.9 age group and 3.0-5.9 age group than that in 6.0-9.9 age group and 10.0-13.9 age group (all P<0.05). No statistical differences were found in the prevalence of allergic rhinitis and dental caries between obese and non-obese children ( P>0.05). Conclusion:The severity of overweight and obesity in children is beyond our expectation, the allergenicity problem is becoming more and more prominent, the prevention and treatment of dental caries needs to be improved urgently, and the phimosis problem in boys needs to be paid attention to.
