OBJECTIVES: To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography. METHODS: Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology. RESULTS: Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis). CONCLUSIONS TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

OBJECTIVE: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies. METHODS: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations. RESULTS: The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery. CONCLUSION Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.

ObjectiveThis study aims to explore the potential molecular mechanism of Gegen Qinliantang （GQL） in the intervention of atherosclerosis （AS） based on network pharmacology and molecular docking. MethodThe active components and targets of each medicinal in GQL were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and AS-related genes from 7 databases. Thereby， the anti-AS targets of GQL were screened out. Cytoscape 3.8.0 was employed to construct the "component-target" network， and STRING the protein-protein interaction （PPI） network. Core targets were screened out with CytoNCA. R clusterProfiler was used for Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment of target genes， which were then visualized. Finally， molecular docking of the top ten active components with the core targets of AS was performed and the binding affinity was compared with that between atorvastatin and the core targets. ResultIn the end， 150 active components of GQL， 20 289 AS targets， and 213 common targets were retrieved， and 48 core common targets were screened out. They were mainly involved in the GO terms of nuclear receptor activity， ligand activation， and transcription factor activity and the pathways of fluid shear force and AS， advanced glycation end products-receptor for advanced glycation end products （AGE/RAGE）， interleukin-17 （IL-17）， tumor necrosis factor （TNF）， Toll-like receptor pathways and other signaling pathways closely related to AS. The molecular docking results showed that the effective components of GQL had high binding affinity to core targets of AS， and the binding affinity was even higher than that between the atorvastatin and core targets. The five groups with high binding affinity were puerarin-TNF， baicalein-inducible nitric oxide synthase 2 （NOS2）， puerarin-NOS2， and formononetin-NOS2， wogonin-NOS2. ConclusionThe above result provides new ideas for further exploration of this classical decoction.

ObjectiveTo explore the mechanism underlying the intervention of Gegen Qinliantang （GQL） in vulnerable plaques in atherosclerosis （AS） of ApoE^-/- mice by regulating the polarization of macrophages. MethodTwelve normal C57BL/6CNC mice were used as the control group， and 60 ApoE^-/- mice of the same line were randomized into 5 groups： model group， low-dose， middle-dose， and high-dose GQL groups （GQL-D， GQL-Z， and GQL-G groups， respectively）， and atorvastatin group （western medicine group）. High-fat diet was used for modeling. The control group and the model group were given （ig） equal volume of sterile distilled water， and GQL-D， GQL-Z， GQL-G， and western medicine groups received （ig） corresponding concentration of drugs for 8 weeks. The levels of total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were detected with biochemical methods. The distribution of plaques in the aortic region was observed based on oil red O staining and hematoxylin-eosin （HE） staining. Serum levels of M1 pro-inflammatory factors tumor necrosis factor （TNF）-α and interleukin （IL）-6 and M2 anti-inflammatory factors IL-13 and transforming growth factor （TGF）-β were detected by enzyme-linked immunosorbent assay （ELISA）. Protein expression of macrophage mannose receptor CD206/arginase-1 （Arg-1） and CD206/inducible nitric oxide synthase （iNOS） was determined by double-labeling immunofluorescence， and mRNA expression of aortic Arg-1 and iNOS by real-time polymerase chain reaction （PCR）. ResultLevels of TG， TC， and LDL-C were significantly lower and HDL-C level was significantly higher in the GQL-Z， GQL-G， and western medicine groups than in the model group. As the concentration of GQL rose， the area with plaques gradually shrunk and the color became lighter. The staining areas of the GQL-G group and the western medicine group were the most scattered. The administration groups showed significant increase in the protein levels of Arg-1 and CD206， significant decrease in the protein level of iNOS， significant rise of Arg-1 mRNA level， and significant drop of iNOS mRNA level （P<0.05）. ConclusionGQL intervenes in the vulnerable plaques in AS by improving lipid metabolism， inhibiting macrophage M1 polarization， promoting macrophage M2 polarization， and further improving the inflammatory microenvironment.

ObjectiveTo explore the effect of Gegen Qinliantang （GQL） on vulnerable plaque of atherosclerosis based on the macrophage pyroptosis mediated by nuclear factor （NF）-κB/NOD-like receptor protein 3 （NLRP3）/cysteine-aspartic acid protease （Caspase）-1 pathway. MethodA total of 12 normal C57BL/6CNC mice were used as the control group， and 60 ApoE^-/- mice of the same line were randomized into 5 groups： model group， low-dose， medium-dose， and high-dose GQL groups （GQL-D， GQL-Z， GQL-G groups， respectively）， and western medicine group. The control group and model group were given （ig） equal volume sterile distilled， and GQL-D， GQL-Z， GQL-G and western medicine groups received （ig） corresponding concentration of drugs for 8 weeks. Aortic plaques were observed based on hematoxylin and eosin （HE） staining. Serum levels of interleukin （IL）-1β and IL-18 were detected by enzyme-linked immunosorbent assay （ELISA）， protein levels of macrophage mannose receptor （CD206）/apoptosis-associated speck-like protein containing a CARD （ASC） and CD206/NLRP3 by double-labeling immunofluorescence， and C-terminal gasdermin D （GSDMD）， N-terminal GSDMD， NLRP3， pro-cysteinyl aspartate specific proteinase 1 （pro-Caspase-1） and NF-κB p65 by Western blot. ResultCompared with the control group， model group demonstrated serious pathological changes， rise of the levels of serum IL-1β and IL-18 and tissue ASC， NLRP3， C-terminal GSDMD， N-terminal GSDMD， pro-Caspase-1， and NF-κB p65， and decrease of CD206 level （P<0.05）. As compared with model group， the administration groups showed alleviation of the lesions in aortic wall， decrease in levels of serum IL-1β and IL-18 and tissue ASC， NLRP3， C-terminal GSDMD， N-terminal GSDMD， pro-Caspase-1， and NF-κB p65， and rise of CD206 level， with significant difference between some groups （P<0.05）. ConclusionGegen Qinliantang alleviates vulnerable plaque of atherosclerosis by regulating NF-κB/NLRP3/Caspase-1 pathway and further relieving macrophage pyroptosis.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

OBJECTIVE Only limited number of drugs are currently available for treating ischemic stroke. Therapeu?tic angiogenesis has recently emerged as one of the most promising therapies for cerebral ischemic injury. Isopropyl-β-(3,4-dihydroxyphenyl)-α-hydroxypropanoate (IDHP) is a metabolite derived from the botanical formulation for Dantonic?. Here, we investigated the angiogenic efficacy of IDHP in cerebral ischemia. METHODS The in vivo effects of IDHP were evaluated in the C57BL/6 mouse Matrigel plug and rat transient middle cerebral artery occlusion (tMCAO) models. Primary human umbilical vein endothelial cells (HUVEC) and human brain microvascular endothelial cells (HBMEC) were used to explore the effects of IDHP on stimulating proliferation, migration and tube formation in vitro. ELISA and Western blotting were used to quantitate the release and expression of relevant target molecules and signaling path?ways. RESULTS IDHP reduced infarct volume and improved sensorimotor function in rats subjected to tMCAO by pro?moting angiogenesis, and promoted Matrigel neovascularization in mice. Moreover, IDHP produced a biphasic modula?tion on proliferation and migration both in HUVEC and HBMEC. It also induced tube formation in a 12-day HUVEC-HDF co-culture model and in Matrigel assays. IDHP-induced angiogenesis was accompanied by increased levels of p-AMPKα (Thr172) and p-eNOS (Ser1177) both in vitro and in vivo, and the decreased level of VEGF in rat brains on day 1 whereas enhanced level of VEGF on day 3 and 7 after tMCAO. Mechanistically, AMPK knockdown or pharmacologi?cally inhibiting AMPK and its upstream kinases (CaMKKβ) inhibited the eNOS phosphorylation induced by IDHP in HUVEC. Furthermore, selective eNOS inhibitor (L-NIO), selective CaMKKβ inhibitor (STO) and AMPKa inhibitor (Com?pound C) blocked the capillary-like tube formation in the co-culture model induced by IDHP (10 nmol · L-1). CONCLU?SION Collectively, these findings showed that IDHP protected rats from cerebral ischemia-reperfusion injury by promot?ing angiogenesis via activating CaMKKβ/AMPK(Thr172)/eNOS(Ser1177) signaling, and suggest it to be a promising new drug candidate for the prevention and/or treatment of cerebral ischemia and other vascular occlusive diseases.

Objective:To analyze the characteristics of clinical manifestation, auxiliary examination and gene mutation of 3-hydroxy-isobutyryl-coenzyme A hydrolase (HIBCH) deficiency to better understand this disease.Methods:The clinical manifestations and genetic results of a patient with HIBCH deficiency were analyzed. The clinical features and genetic characteristics of HIBCH deficiency were summarized based on the literature review.Results:The proband, female, one year and four months old, was admitted to Children′s Hospital Affiliated to Zhengzhou University for “vomiting and diarrhea for 15 days, dyspnea and intermittent convulsions for 13 days after digestive tract infection”. The intelligence was normal, however, the motor development was slightly delayed before onset. Physical examination showed light coma, poor response and insensitivity to light. She also had shortness of breath, weak positive three concave signs and coarse breath sound in both lungs with sputum purrs. In addition, the muscle tension of extremities was increased. Bilateral Brudzinski′s sign, Babinski′s sign and Kernig′s sign were negative. Serum hydroxybutyryl carnitine (C4OH) was increased. Cranial magnetic resonance imaging (MRI) showed atrophy in bilateral cerebral hemispheres and abnormal symmetry signals in bilateral globus pallidus and cerebral peduncle. Novel compound heterozygous variants of HIBCH, c.489T>A (p. C163*) and c.740A>G (p. Y247C), were found in the patient, which respectively inherited from her healthy parents. Her symptoms were relieved after“cocktail”therapy and symptomatic treatment. Literature related to HIBCH deficiency published all around the world was reviewed. As a result, 17 articles, including 24 cases, had been reported. The majority of patients presented with poor feeding, dystonia and progressive motor developmental delay in early infancy. Cranial MRI showed lesions in bilateral basal ganglia. Serum C4OH concentration was elevated. And compound heterozygous or homozygous variants of HIBCH gene were found in patients with HIBCH deficiency.Conclusions:The detection of serum amino acids and acylcarnitine profiles on HIBCH deficiency was relatively specific and it was helpful to make a clear diagnosis by combining with cranial MRI and genetic tests. In this study, a case of HIBCH deficiency was confirmed, which expanded the mutation spectrum of HIBCH gene. Meanwhile, summarizing the clinical and genetic characteristics of cases reported improved understanding of HIBCH deficiency.

Membrane-disruptive peptides/peptidomimetics (MDPs) are antimicrobials or anticarcinogens that present a general killing mechanism through the physical disruption of cell membranes, in contrast to conventional chemotherapeutic drugs, which act on precise targets such as DNA or specific enzymes. Owing to their rapid action, broad-spectrum activity, and mechanisms of action that potentially hinder the development of resistance, MDPs have been increasingly considered as future therapeutics in the drug-resistant era. Recently, growing experimental evidence has demonstrated that MDPs can also be utilized as adjuvants to enhance the therapeutic effects of other agents. In this review, we evaluate the literature around the broad-spectrum antimicrobial properties and anticancer activity of MDPs, and summarize the current development and mechanisms of MDPs alone or in combination with other agents. Notably, this review highlights recent advances in the design of various MDP-based drug delivery systems that can improve the therapeutic effect of MDPs, minimize side effects, and promote the co-delivery of multiple chemotherapeutics, for more efficient antimicrobial and anticancer therapy.
