Objective To explore the changes and predictive value of serum interleukin-1(IL-1),interleu-kin-12(IL-12)and interferon α(IFN-α)levels in early pregnancy in hepatitis B pregnant women with abnor-mal liver function.Methods A total of 100 hepatitis B pregnant women with normal liver function in early pregnancy in Shijiazhuang Maternal and Child Health Hospital from January 2022 to May 2022 were selected,and were divided into normal liver function group(52 cases)and abnormal liver function group(48 cases)ac-cording to whether there was abnormal liver function in middle and late pregnancy,and another 50 healthy pregnant women of the same gestational week in the same period in Shijiazhuang Maternal and Child Health Hospital were selected as the control group.The general information,liver function indicators[alanine amin-otransferase(ALT),aspartate aminotransferase(AST),glutamine transferase(GGT)],serum interleukin(IL)-1,IL-12,and interferon α(IFN-α)levels among the three groups were compared.The serum levels of IL-1,IL-12,IFN-α in pregnant women with different degrees of liver dysfunction in the liver dysfunction group were compared,and the relationship between the serum levels of IL-1,IL-12,IFN-α and the degree of liver dysfunction was analyzed,as well as the value of predicting liver dysfunction in pregnant women with hepatitis B in the middle and late pregnancy.Results The serum levels of ALT,AST,GGT,IL-1 and IL-12 in early pregnancy from high to low in three groups were liver dysfunction group,normal liver function group,and control group(P＜0.05),while the level of IFN-α in early pregnancy from low to high in three groups were liver dysfunction group,normal liver function group,and control group(P＜0.05).In the abnormal liver func-tion group,there were 12 cases with abnormal concentration values of 3 enzymes,16 cases with abnormal con-centration values of 2 enzymes,and 20 cases with abnormal concentration values of 1 enzyme.The levels of IL-1 and IL-12 from high to low were pregnant women with 3 abnormal values of enzyme,2 abnormal values of enzyme,and 1 abnormal value of enzyme(P＜0.05).The level of IFN-α from low to high were pregnant women with 3 abnormal values of enzyme,2 abnormal values of enzyme,and 1 abnormal value of enzyme(P＜0.05).The levels of serum IL-1 and IL-12 in the abnormal liver function group were positively correlated with the degree of liver function abnormality(r=0.771,0.793,P＜0.05),while the levels of IFN-α were negatively correlated with the degree of liver function abnormality(r=-0.755,P＜0.05).The area under the curve of serum IL-1,IL-12 and IFN-α in the early pregnancy for predicting abnormal liver function of hep-atitis B pregnant women in the middle and late pregnancy was 0.936(95％CI:0.869-0.976,P＜0.05).Conclusion The levels of serum IL-1,IL-12 and IFN-α in early pregnancy of hepatitis B pregnant women are closely related to the degree of liver dysfunction in the middle and late pregnancy,and the combined detection of the three serum indicators has a high predictive value for predicting the liver dysfunction in the middle and late pregnancy of hepatitis B pregnant women.

Objective:To investigate the clinical phenotype and gene mutation in a child with developmental disorders caused by CTNNB1 gene mutation. Methods:Clinical data of a child with CTNNB1 gene mutation who was admitted to Xiamen Hospital of Fudan University Affiliated Pediatric Hospital in May 2017 were collected, whole exome sequencing technology was applied to verify the family lineage of the child, and the pathogenicity of mutation site was analyzed. Results:The patient was a 6 years and 1 month old male, with a clinical phenotype including mental retardation, motor developmental disorders, speech disorders, visual disorders (internal strabismus), microcephaly, and behavioral problems (social withdrawal, overdependence, etc.), as well as panic syndrome (i.e., sudden shrieking in response to auditory and visual stimuli, extensional rigidity of the body, etc., followed by short periods of general extensional rigidity). The whole exome sequencing results showed the presence of a de novo mutation c.283(exon4)C>T in the CTNNB1 gene, and the c.283(exon4)C>T mutation was interpreted as pathogenic (PVS1+PS2+PS1+PM2+PM) according to the American College of Medical Genetics and Genomics variant classification criteria and guidelines. No relevant genetic variants were found in the parental family verification. Conclusion:CTNNB1 gene mutation c.283(exon4)C>T can cause neurodevelopmental disorders, including mental retardation, motor developmental disorders, speech disorders, visual disorders, microcephaly and behavioral abnormalities.

Thioredoxin-interacting protein (TXNIP), which mainly regulates glucose homeostasis in pancreatic β cells, is a novel target in the treatment of diabetes.In this study, 4-hydroxybenzopyrimidine was used as the raw material, four nitrogen-containing rings (imidazole, methylpiperazine, pyrazole, morpholine) were introduced, benzopyrimidine skeleton with nitrogen-containing rings derivatives targeting TXNIP was designed and synthesized, and the protective effect of compounds on palmitic acid-stimulated islet β cells was investigated.A total of 20 benzopyrimidine derivatives were designed and synthesized, and the structures were confirmed by 1H NMR and ESI-MS.Pharmacological studies showed that most of the compounds exhibited protective effects on islet β cells, with better axtivity for compounds C-1, C-2, C-4 and D-2 (cell survival rate > 70%) compared with PA model group (38.3%), Among the four compounds, D-2 had the highest activity of 87.2%, so it could become a potential new anti-diabetic chemical entity.

Ferulic acid (FA), a natural product of phenylpropanoids containing phenolic hydroxyl groups, has a wide range of pharmacological activities and some therapeutic effect on Alzheimer's disease (AD).Using FA as the raw material, the ferulic acid carbamate aniline derivatives were first synthesized by 4-step esterification reaction, splicing carbamate active functional groups, hydrolysis reaction and amide condensation.These FA derivatives were evaluated for in vitro cholinesterase inhibition activity by the Ellman method.A total of 15 novel FA derivatives were designed and synthesized, and their structures were confirmed by 1H NMR, 13C NMR and ESI-MS.Cholinesterase activity tests showed that compounds 5c, 5f, 5j, 5g, 5m possessed good acetylcholinesterase inhibition activity.Except for 5l, 5m, almost all compounds have inhibition activity on butyrylcholinesterase, which is much higher than that on acetylcholinesterase.In conclusion, compounds 5c, 5f, 5j and 5g can be used as potential anti-AD inhibitors targeting cholinesterase..

Fever is a sign of infection and inflammatory diseases in the body. Persistent high fever will lead to cell degeneration, causing multiple organ dysfunction, and seriously affecting brain nerve and tissue function. Although the fever process is common and ordinary, its pathological mechanism involves multiple signaling pathways, such as nuclear transcription factor κB signaling pathway, Toll-like receptor 4 signaling pathway. A large number of studies have shown that traditional Chinese medicine compound and its active components can reduce serum inflammatory factors (TNF-α, IL-1β and IL-6) and hypothalamic thermoregulatory mediators (PGE

Using syringaldehyde as raw material, the phosphine ylide intermediate was efficiently synthesized through acetylated hydroxyl protection, aldehyde group reduction, chlorination and reaction with triphenylphosphine. On this basis, moscatilin (MST) and its 12 analogs (MST-1-MST-12) were synthesized by wittig reaction, deacetylation and double bond reduction. All the structures were confirmed by 1H NMR, 13C NMR and ESI-MS. Bacterial lipopolysaccharide-induced mouse macrophage RAW264.7 inflammation model was used to conduct preliminary anti-inflammatory activity tests in vitro for the target compounds. Results showed that all compounds could inhibit the production of inflammatory factor NO, and that MST-5 exhibited the strongest anti-inflammatory activity (IC50= 0.428 μmol/L).Further exploration is expected for the study of the anti-inflammatory mechanism of MST-5.

Objective:To establish a disease risk prediction model for the newborn screening system of inherited metabolic diseases by artificial intelligence technology.Methods:This was a retrospectively study. Newborn screening data ( n=5 907 547) from February 2010 to May 2019 from 31 hospitals in China and verified data ( n=3 028) from 34 hospitals of the same period were collected to establish the artificial intelligence model for the prediction of inherited metabolic diseases in neonates. The validity of the artificial intelligence disease risk prediction model was verified by 360 814 newborns ' screening data from January 2018 to September 2018 through a single-blind experiment. The effectiveness of the artificial intelligence disease risk prediction model was verified by comparing the detection rate of clinically confirmed cases, the positive rate of initial screening and the positive predictive value between the clinicians and the artificial intelligence prediction model of inherited metabolic diseases. Results:A total of 3 665 697 newborns ' screening data were collected including 3 019 cases ' positive data to establish the 16 artificial intelligence models for 32 inherited metabolic diseases. The single-blind experiment ( n=360 814) showed that 45 clinically diagnosed infants were detected by both artificial intelligence model and clinicians. A total of 2 684 cases were positive in tandem mass spectrometry screening and 1 694 cases were with high risk in artificial intelligence prediction model of inherited metabolic diseases, with the positive rates of tandem 0.74% (2 684/360 814)and 0.46% (1 694/360 814), respectively. Compared to clinicians, the positive rate of newborns was reduced by 36.89% (990/2 684) after the application of the artificial intelligence model, and the positive predictive values of clinicians and artificial intelligence prediction model of inherited metabolic diseases were 1.68% (45/2 684) and 2.66% (45/1 694) respectively. Conclusion:An accurate, fast, and the lower false positive rate auxiliary diagnosis system for neonatal inherited metabolic diseases by artificial intelligence technology has been established, which may have an important clinical value.

The coronavirus disease 2019 (COVID-19) has caused a global pandemic. All people including children are generally susceptible to COVID-19, but the condition is relatively mild for children. The diagnosis of COVID-19 is largely based on the epidemiological evidence and clinical manifestations, and confirmed by positive detection of virus nucleic acid in respiratory samples. The main symptoms of COVID-19 in children are fever and cough; the total number of white blood cell count is usually normal or decreased; the chest imaging is characterized by interstitial pneumonia, which is similar to other respiratory virus infections and infections. Early identification, early isolation, early diagnosis and early treatment are important for clinical management. The treatment of mild or moderate type of child COVID-19 is mainly symptomatic. For severe and critical ill cases, the oxygen therapy, antiviral drugs, antibacterial drugs, glucocorticoids, mechanical ventilation or even extracorporeal membrane oxygenation (ECMO) may be adopted, and the treatment plan should be adjusted timely through multi-disciplinary cooperation.
