Objective:To investigate the clinical efficacy and safety of a baby smoothing and special caring cream in reducing the recurrence of atopic dermatitis (AD) in infancy.Methods:A randomized controlled trial was conducted. Children with moderate AD (with overall investigator's global assessment [IGA] scores of 3 - < 4) were enrolled from Shunyi Maternal and Children′s Hospital of Beijing Children′s Hospital from April 2021 to June 2024. During the induction period, all children were topically treated with 0.1% hydrocortisone butyrate cream twice daily on the lesional skin, as well as with a baby smoothing and special caring cream at least twice daily throughout the body; at the 2-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those with an IGA score of > 1 point continued the treatment for another 2 weeks; at the 4-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those still with an IGA score of > 1 point were withdrawn from the study, and received conventional treatment. Patients who entered the maintenance period were randomly divided into the test group and the control group in a 1∶1 ratio using a random number table. In the test group, the hydrocortisone butyrate cream was discontinued, while the baby smoothing and special caring cream was continued twice daily for 8 consecutive weeks; in the control group, both the hydrocortisone butyrate cream and the baby smoothing and special caring cream were discontinued. IGA and Scoring AD (SCORAD) scores were assessed by clinicians at weeks 4 and 8 in the maintenance phase, while the patient-oriented eczema measure (POEM) score was evaluated weekly by patients' parents. The Kaplan-Meier survival analysis and Breslow test were used to compare recurrence rates in the two groups (the primary efficacy outcome), and a generalized estimating equation model was used to evaluate the changes in IGA, SCORAD, and POEM scores in the two groups (the secondary efficacy outcomes). Adverse reactions were monitored throughout the study to evaluate safety.Results:A total of 68 children with moderate AD aged from 3 months to 2 years were included. There were 38 females and 30 males, aged 11.72 ± 6.03 months. Fifty-two patients entered the maintenance phase; 2 were lost to follow-up, and 50 were included in the per-protocol set, with 28 in the test group and 22 in the control group. The recurrence rate during the maintenance phase was 7.14% (2/28) in the test group and 31.82% (7/22) in the control group, showing a significant difference between the two groups ( χ 2 = 5.08, P = 0.032). At weeks 4 and 8 in the maintenance phase, the IGA scores were significantly lower in the test group than in the control group (Wald χ 2 = 5.06, P = 0.024), whereas the SCORAD scores showed no significant differences between the two groups (Wald χ 2 = 2.92, P = 0.087). During weeks 1 - 8 in the maintenance phase, the POEM scores showed no significant differences between the two groups or over time (both P > 0.05), while the two groups showed different change trends in POEM scores over time (Wald χ 2interaction = 55.37, Pinteraction < 0.001). Throughout the entire study period, no adverse reactions were observed among all 68 subjects. Conclusion:With a high safety profile, the baby smoothing and special caring cream could reduce the recurrence rate during the maintenance phase, showing promise as an adjuvant therapy for the maintenance treatment of AD in infancy, and is worthy of clinical application.

Objective To utilize single-cell and peripheral blood transcriptomic data from 3D brain organoids,combined with machine learning,to analyze the role of mitochondrial autophagy genes in schizophrenia(SCZ).Methods By integrating two machine learning algorithms,we identified differentially expressed mitochondrial autophagy-related genes between schizophrenia patients and healthy controls using peripheral blood RNA sequencing data.The relationship between mitophagy gene,immune cells and inflammatory factors was further explored.Comprehensive single-cell analysis was used to explore the signaling pathways and specific transcription factors based on mitophagy genes.Results Using machine learning,seven key mitophagy genes expressed in schizophrenia patients were identified.Based on Mitoscore analysis,at the single-cell level,neurons with high mitochondrial autophagy activity(Mitohigh_Neuron)formed new interactions with endothelial cells via the SPP1 signaling pathway.Conclusion This study identified two subtypes of mitophagy and seven key mitophagy genes in schizophrenia,providing new insights into the pathogenesis of the disease.

Objective:To investigate the relationship between the duration of the second stage of labor and the amount of postpartum hemorrhage within 2 hours in primiparas using epidural analgesia.Methods:A retrospective study was conducted on the clinical data of pregnant women who delivered vaginally in the obstetrics department of the Affiliated Hospital of Jining Medical University from January 1, 2020, to December 31, 2020. The data included maternal age, pre-pregnancy body mass index (BMI), gravidity, gestational age at delivery, weight gain during pregnancy, common pregnancy complications (such as gestational hypertension, gestational diabetes, hypothyroidism, and pregnancy-related anemia), types of uterotonics, duration of each stage of labor, delivery outcomes, perineal conditions, postpartum hemorrhage within 2 hours, and neonatal birth length and weight. The exposure variable was the duration of the second stage of labor, and the outcome was the amount of postpartum hemorrhage within 2 hours. Potential risk factors were analyzed using univariate analysis. After adjusting for potential confounding factors, a generalized additive model was used for linear regression analysis, smooth curve fitting, and threshold effect analysis to observe the relationship between the duration of the second stage of labor and postpartum hemorrhage within 2 hours.Results:A total of 2 067 primiparas were included in the study. The mean age of the participants was 26.5±3.6 years, the median duration of the second stage of labor was 54 min (range: 35-81 min), and the median amount of postpartum hemorrhage within 2 hours was 230 ml (range: 200-300 ml). After adjusting for factors such as maternal age, pre-pregnancy BMI, gestational age at delivery, vaginal delivery, duration of the first and third stages of labor, perineal conditions, types of uterotonics used within 2 hours postpartum, and neonatal birth length and weight, a positive relationship was found between the duration of the second stage of labor and the amount of postpartum hemorrhage within 2 hours ( ?=0.20, 95% CI: 0.00-0.30, P<0.05). The smooth curve fitting results showed a non-linear relationship between the duration of the second stage of labor and postpartum hemorrhage within 2 hours. Threshold effect analysis indicated that the two-segment regression model (Model Ⅱ) was more suitable for fitting the correlation compared to the univariate linear regression model (Model Ⅰ), with a log-likelihood ratio test P-value of 0.001, and the inflection point was 115 min for the second stage of labor (95% CI: 99-125 min). Conclusions:In primiparas using epidural analgesia, there is a non-linear relationship and threshold effect between the duration of the second stage of labor and the amount of postpartum hemorrhage within 2 hours. When the second stage of labor exceeds 115 min, the extension of the second stage may increase the amount of postpartum hemorrhage within 2 hours.

The second edition of the Chinese guideline for the prevention and treatment of anxiety disorders was published in August 2023, 13 years after the first edition. The revision principles for the second edition were maintaining the first edition's framework, and based on that framework, making necessary revisions by incorporating research progress and supplementing the latest research findings from the domestic studies and the overseas literature. Referring to the DSM-5 and ICD-11 classifications of mental disorders and the actual clinical situation in China, the anxiety disorders in the second edition were panic disorder, generalized anxiety disorder, social anxiety disorder, separation anxiety disorder, and anxiety disorder due to another medical condition. The latest epidemiological data on anxiety disorders in China were added. Following the international guidelines, medications not included in the first edition have been added. Chinese traditional medicines, physical therapy, and internet web-based psychotherapy were also supplemented to fit Chinese clinical settings. Based on a literature review, the latest information on the risks of using antidepressants during pregnancy has been added.A whole course of treatment across the acute phase, consolidation phase, and maintenance phase was further addressed as the treatment principle. First-line and second-line recommendations are provided for medication selections.

Objective To investigate the fertility history and demand for reproductive health services of new residents in Shanghai. Methods A questionnaire survey was conducted among 1 358 new residents in 36 survey sites in 7 districts of Shanghai from July to September 2020. The content includes fertility history， induced abortion history， demand for reproductive health-related services， awareness rate of the Shanghai Family Planning Association and service access rate， etc. Results Among the new residents themselves and their spouses/sexual partners， 31.3% （374/1 194） had been pregnant once and 33.6% （401/1 194） had been pregnant twice； 46.3% （533/1 194）had one child and 29.7% （355/1 194）had two children. The difference of number of births among new residents with different residence time， those who did or did not possess permanent residency or residence permits， and those from different sources （urban or rural） was statistically significant （ χ ²=158.664， 50.263， 16.011， 114.419， all P <0.001）. Among the new residents themselves and their spouses / sexual partners， the proportion of induced abortion of more than once was 36.1%. The difference of the number of abortions of new residents with or without permanent residency was statistically significant （ χ ²=19.389， P <0.001）. The awareness rate of new residents of the harm of induced abortion to health was 92.1% （1 100/1 194）； There were significant differences in the scientific knowledge of harm of induced abortion to health among new residents with different local residence time and those with or without a residence permit （ χ ²=36.590， 20.926， both P <0.001）. The awareness rate of the Family Planning Association was 82.6% （986/1 194）， and the service access rate was 51.3% （613/1 194）. Permanent residency and residence permits are the main factors that affect the service accessibility of the Shanghai Family Planning Association. 44.8% （535/1 194） of new residents hope to receive reproductive health services in their place of residence， and they are most concerned about knowledge on good prenatal and postnatal care. Conclusion We should further publicize the "three-child" fertility policy， advocate a friendly fertility culture， and provide new residents with people-centered and accurate reproductive health services adapted to their needs through multi-sectoral cooperation， so as to improve their reproductive health level.

Objective To investigate and evaluate the changes in total α and total β radioactivity levels in drinking water in Beijing, China, 2012—2021. Methods The test results of total α and total β radioactivity levels at 14 monitoring sites from 9 groundwater sources and 5 surface water sources in Beijing, 2012—2021 were collected. The radioactivity levels in the two types of water sources were compared. Statistical charts were used to show the monitoring situation at sampling sites in different regions during different periods, and related issues were explored. Results The total α and total β activity concentrations measured at monitoring sites from some water sources in Beijing, 2012—2021, were less than the total α and total β guideline values specified in the Standards for Drinking Water Quality (GB 5749—2006) (total α: 0.5 Bq/L, total β: 1.0 Bq/L). The mean total α activity concentration in the groundwater was significantly higher than that in the surface water. The total α and total β radioactivity levels in the reservoir D in the surface water were slightly higher than those in the other surface water. Conclusion In the past decade from 2012 to 2021, the total α and total β radioactivity levels in some water sources in Beijing were generally in a good condition and fluctuated within the range of environmental background values, without significant changes on the whole.

Amplifying "eat me signal" during tumor immunogenic cell death (ICD) cascade is crucial for tumor immunotherapy. Inspired by the indispensable role of adenosine triphosphate (ATP, a necessary "eat me signal" for ICD), a versatile ICD amplifier was developed for chemotherapy-sensitized immunotherapy. Doxorubicin (DOX), ATP and ferrous ions (Fe²⁺) were co-assembled into nanosized amplifier (ADO-Fe) through π‒π stacking and coordination effect. Meanwhile, phenylboric acid-polyethylene glycol-phenylboric acid (PBA-PEG-PBA) was modified on the surface of ADO-Fe (denoted as PADO-Fe) by the virtue of d-ribose unit of ATP. PADO-Fe could display active targetability against tumor cells via sialic acid/PBA interaction. In acidic microenvironment, PBA-PEG-PBA would dissociate from amplifier. Moreover, high H₂O₂ concentration would induce hydroxyl radical (·OH) and oxygen (O₂) generation through Fenton reaction by Fe²⁺. DOX and ATP would be released from the amplifier, which could induce ICD effect and "ICD adjuvant" to amplify this process. Together with programmed death ligands 1 (PD-L1) checkpoint blockade immunotherapy, PADO-Fe could not only activate immune response against primary tumor, but also strong abscopal effect against distant tumor. Our simple and multifunctional ICD amplifier opens a new window for enhancing ICD effect and immune checkpoint blockade therapy.
