ObjectiveTo investigate the effects and potential mechanisms of morning and evening fasting on postprandial lipid responses, a post hoc analysis based on a crossover randomized controlled trial was conducted to assess the effects of different fasting strategies on postprandial lipid metabolism in community residents in Shanghai. MethodsA total of 23 participants took part in a randomized crossover trial involving two intervention days: morning fasting and evening fasting, with a washout period of 6 days between intervention days. Two-way analysis of variance was used to test the differences in total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and the relative expression of circadian clock genes before and after the next meal under fasting. Wilcoxon rank sum tests were used to analyze the different metabolites between the two groups. Principal component analysis and Orthogonal partial least squares-discriminant analysis were conducted to evaluate the ability of metabolites to differentiate between morning fasting and evening fasting and identify the important differential metabolites. After adjusting for age, sex, and BMI, a partial correlation analysis was performed to identify metabolites associated with plasma lipids. In addition, important metabolites associated with plasma lipids were computed by pathway enrichment analysis. ResultsAfter evening fasting intervention, fasting TG level [(0.37±0.29) vs (0.27±0.18)] mmol·L^-1, fasting and postprandial change values in TC [(2.74±0.47) vs (2.51±0.27)] mmol·L^-1 and LDL-C [(1.32±0.38) vs (0.99±0.27)] mmol·L^-1 were significantly lower than those after morning fasting (P<0.05). While, change values of fasting LDL-C [(0.89±0.37) vs (1.14±0.37)] mmol·L^-1 and TG [(1.14±0.19) vs (1.28±0.17)] mmol·L^-1 were significantly higher than those after morning fasting intervention (P<0.05). After fasting intervention, the relative expression of AMPK, CRY1, CLOCK, MTNR1B, AANAT, and ASMT was correlated with the amount of plasma lipid changes (P<0.05). Specifically, CLOCK and AANAT were upregulated following evening fasting and downregulated after morning fasting. Among the 217 important differential metabolites, 111 were correlated with plasma lipids, and which were primarily enriched in the cysteine and methionine metabolism pathways (P<0.05). ConclusionCompared to morning fasting, evening fasting was more effective in improving postprandial lipid responses, indicating that an evening fasting window during intermittent fasting could be conducive to cardiovascular disease prevention in adults. Meanwhile, it is suggested that morning and evening fasting may affect lipid responses through circadian rhythm oscillations and the cysteine and methionine metabolism pathways.

Objective:To evaluate the role of stimulator of interferon genes (STING) in postoperative cognitive dysfunction (POCD) and the relationship with pyroptosis in hippocampal cells in aged mice.Methods:Forty-eight SPF healthy male C57BL/6 mice, aged 18 months, weighing 23-28 g, were assigned to 4 groups ( n=12 each) using a random number table method: control group (C group), POCD group (P group), STING inhibitor C-176 group (PC group), and C-176 solvent group (PV group). The mice underwent Morris water maze training for 4 days prior to model establishment. Mice in P, PC and PV groups underwent tibial fracture and intramedullary pin fixation under sevoflurane anesthesia to establish the POCD model, while mice in C group received no treatment. The STING inhibitor C-176 (750 nmol/200 μl) and an equal volume of C-176 solvent were intraperitoneally injected at 30 min before establishment of the model in PC and PV groups, respectively. The open field test was performed on the 5th day after model preparation, the novel object recognition test was conducted on the 6th day, and the Morris water maze test was performed on the 7th day. Mice were sacrificed under anesthesia to collect the hippocampus for determination of the expression of STING, phosphorylated STING (p-STING), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), cleaved caspase-1, and gasdermin-D (GSDMD)-NT by Western blot. Results:There were no statistically significant differences in the parameters of the training phase of the Morris water maze test and the open field test among the four groups ( P>0.05). Compared with C group, the recognition index in the novel object recognition test was significantly decreased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was shortened in the Morris water maze test, and the expression of STING, NLRP3, cleaved caspase-1, and GSDMD-NT in hippocampal neurons was up-regulated in P, PC and PV groups, and the expression of p-STING was significantly up-regulated in P and PV groups ( P<0.05). Compared with P group, the recognition index in the novel object recognition test was significantly increased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was prolonged in the Morris water maze test, and the expression of p-STING, NLRP3, cleaved caspase-1, and GSDMD-NT in hippocampal neurons was down-regulated in PC group ( P<0.05). Compared with PC group, the recognition index in the novel object recognition test was significantly decreased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was shortened in the Morris water maze test, and the expression of p-STING, NLRP3, cleaved caspase-1 and GSDMD-NT was up-regulated in PV group ( P<0.05). Conclusions:STING is involved in the development of POCD in aged mice, and the mechanism may be related to promotion of pyroptosis in hippocampal cells.

Objective:To analyze the changing trends and international differences in the incidence and disability-adjusted life years (DALY) of hypertensive disorders in pregnancy (HDP) in China from 1990 to 2021 based on the Global Burden of Disease (GBD) database.Methods:The data were derived from the GBD database, covering the incidence and DALY data of HDP in countries or regions around the world. Descriptive statistics were used to compare the differences in disease burden between China and different regions of Europe, America and other developed countries, and to analyze the disease burden characteristics of women of childbearing age in different age groups (every 5 years). The Joinpoint regression model was used to identify trend change points. The age-period-cohort model was used to analyze the independent effects of age, period and birth cohort.Results:(1) From 1990 to 2021, the incidence of HDP in China showed an overall downward trend, from 387.18/100 000 in 1990 to 216.35/100 000 in 2021. Compared with the global incidence rate (1990: 1 167.28/100 000; 2021: 923.48/100 000), the incidence rate of HDP in China was relatively low, but it was still higher than that in some developed countries. (2) The analysis of the Joinpoint regression model showed that the incidence rate of HDP in different age groups first decreased, then increased, and finally leveled off. The connection point with the lowest point was in 2005. DALY showed a continuous downward trend in all age groups. Among them, the decline in maternal DALY of pregnant women in all age groups from 15 to 39 years old was more obvious. (3) The age-period-cohort effect model showed that the incidence rate and DALY of HDP in women of childbearing age aged 20 to 24 years reached their peak.Conclusions:The burden of HDP in China continues to decrease, and the disease prevention and control has achieved remarkable results, but the incidence rate is still higher than that in some developed countries. It is suggested that personalized interventions should be developed for different risk groups to further reduce the burden of disease.

Objective:To investigate the mode and timing of delivery in pregnant women with complex fetal congenital heart disease (CHD) detected by prenatal ultrasound.Methods:The clinical data of 123 fetuses with complex CHD detected by prenatal ultrasound in Peking University People′s Hospital from January 2016 to December 2023 were retrospectively analyzed. Pregnant women with indications for prenatal diagnosis underwent G-banding karyotype analysis, single nucleotide polymorphism array (SNP arrry) or whole exome sequencing after informed consent. Integrated managements were provided for pregnant women with complex CHD during pregnancy and perinatal period, and to determine the mode and timing of delivery. Infants with complex CHD received timely treatment or referral after birth.Results:The gestational age at ultrasound diagnosis of the 123 fetuses with complex CHD was (23.7±3.4) weeks. There were 11 cases (8.9%) of total anomalous pulmonary venous connection (TAPVC), 14 cases (11.4%) of anomalous pulmonary valve (PVA), 7 cases (5.7%) of right ventricle double outlet (RVDO), 13 cases (10.6%) of anomalous aortic arch, 69 cases (56.1%) of transposition of the great arteries (TGA), 9 cases (7.3%) of other types. All cases were treated with fetal preservation after prenatal consultation. Among the 72 cases undergoing prenatal diagnosis, 9 cases (12.5%) had chromosomal variations. Fifty-five cases (44.7%, 55/123) underwent trial of labor, of which 46 cases (37.4%, 46/123) had successful vaginal delivery, including 6 cases of forceps delivery, and other 9 cases of failed trial of labor transferred to cesarean section. A total of 77 cases of pregnant women underwent cesarean section. Except for the 21 cases of pregnant women who asked for cesarean section, the cesarean section rate of pregnant women with complex CHD was 45.5% (56/123), which was not significantly different from the average cesarean section rate of the same period in our hospital (40.2%; χ2=7.34, P=0.270). The gestational age at delivery of the 123 fetuses with complex CHD was (37.9±1.4) weeks, the birth weight of the neonates was (3 099±480) g, and the umbilical artery blood pH value was 7.31±0.05. The oxygen saturation of 86 cases before and after alprostadil infusion were (72.8±6.0)% and (80.5±5.0)%, respectively, and the difference was statistically significant ( t=4.38, P<0.001). One hundred and fourteen children underwent surgical treatment, 112 of them (98.2%) had good postoperative reexamination. Only 2 cases (1.8%) died after surgery, and 14.0% (16/114) had the possibility of secondary surgery. Conclusions:Fetal complex CHD is not an indication for cesarean section, and the delivery mode could be selected according to the obstetric situation. If the mother and child are in stable condition, the delivery is planned after 39 weeks of gestation. For children with low oxygen saturation after birth, alprostadil could be pumped to maintain the open ductus arteriosus, and timely referral to the pediatric cardiac surgery for subsequent surgical treatment, which could achieve a good prognosis.

Objective:To compare the efficacy of new nasopharyngeal airway and laryngeal mask airway for airway management in the patients undergoing non-intubated video-assisted thoracoscopic surgery (NIVATS).Methods:In this randomised, controlled, non-inferiority trial, 60 American Society of Anesthesiologists Physical Status classification I or Ⅱ patients of both sexes, aged 18-79 yr, scheduled for elective NIVATS from December 2021 to December 2023 at Jining No.1 People′s Hospital, were divided into 2 groups ( n=30 each) using a computer-generated random code in a 1∶1 ratio: new type nasopharyngeal airway group (group N) and laryngeal mask airway group (group L). After anesthesia induction, a new nasopharyngeal airway was inserted in group N, and a laryngeal mask airway was inserted in group L. Spontaneous ventilation was maintained during the NIVATS. Ultrasound-guided serratus anterior plane block was performed on the affected side before anesthesia induction. Anesthesia was maintained with propofol and remifentanil. The primary outcome measure was the rate of intraoperative airway intervention, the airway interventions included repositioning of the airway tools, manual assisted ventilation, jaw-thrust maneuver, and conversion to endotracheal intubation. The secondary outcome measures included the first-attempt success rate of airway device placement, time for establishing a patent airway, the minimum value of SpO 2, the maximum value of P ETCO 2, and incidence of complications such as postoperative sore throat. Results:The rate of intraoperative airway intervention was 27% in group L and 47% in group N ( χ2=2.58, P=0.108). The difference in the rate of intraoperative airway intervention between the two groups was 0.20 (95% confidence interval 0.15-0.25), with a 95% confidence interval upper limit higher than the non-inferiority boundary (10%), indicating that this non-inferiority hypothesis was not established. In comparison to group L, the rate of intraoperative jaw-thrust maneuver intervention was significantly increased, the time to establish a patent airway was shortened, and the incidence of postoperative sore throat was decreased in group N ( P<0.05). Conclusions:Compared with the laryngeal mask airway, the new nasopharyngeal airway can reduce the development of postoperative throat pain, however, it is less effective in maintaining a patent airway. It requires careful consideration of risks and benefits when used for NIVATS.

Objective To investigate the influencing factors for the short-term prognosis of patients with alcohol-related liver diseases-acute-on-chronic liver failure(ALD-ACLF)comorbid with infection.Methods A total of 89 ALD-ACLF patients with infection who were admitted to the Fifth Medical Center of PLA General Hospital from January 2019 to December 2021 were enrolled as subjects,and related clinical data were collected at baseline(time of patient enrollment).According to the 28-day survival status of patients,they were divided into survival group with 53 patients and death group with 36 patients,and baseline clinical data were compared between the two groups.The t-test was used for comparison of normally distributed continuous data between groups,and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups;the chi-square test was used for comparison of categorical data between groups.A non-conditional Logistic regression analysis was used to perform the multivariate analysis.The Z-test was used for comparison of the area under the ROC curve(AUC),and the diagnostic value of the model was assessed.Results Compared with the survival group,the death group had significantly higher hemoglobin(t=-2.397,P=0.019),alanine aminotransferase(Z=-3.437,P=0.001),gamma-glutamyl transpeptidase(Z=-2.617,P=0.009),creatinine(Z=-3.938,P<0.001),blood urea nitrogen(Z=-3.423,P=0.001),NH3(Z=-4.406,P<0.001),international normalized ratio(Z=-3.428,P=0.001),C-reactive protein(Z=-2.128,P=0.033),procalcitonin(Z=-2.441,P=0.015),Model for End-Stage Liver Disease(MELD)score(t=-4.817,P<0.001),incidence rate of acute kidney injury(χ2=21.602,P<0.001),incidence rate of pulmonary infection(χ2=4.866,P=0.027),and incidence rate of shock(χ2=16.285,P<0.001),as well as significantly lower albumin(Z=-2.473,P=0.013)and incidence rate of abdominal infection(χ2=5.897,P=0.015).The multivariate analysis showed that NH3(odds ratio[OR]=1.027,95%confidence interval[CI]:1.006-1.049,P=0.012),MELD score(OR=1.103,95%CI:1.011-1.203,P=0.027],and the incidence rate of shock(OR=6.326,95%CI:1.533-26.101,P=0.011)were independent risk factors for 28-day mortality in ALD-ACLF patients comorbid with infection.Based on these factors,a predictive model was established as Y=0.027×NH3+0.098×MELD score+1.845×shock-4.111.The ROC curve analysis showed that the new model had an AUC of 0.861,a sensitivity of 77.78%,and a specificity of 88.68%,while MELD score had an AUC of 0.776,a sensitivity of 77.78%,and a specificity of 67.92%,suggesting that the new model had a significantly higher diagnostic value than MELD score(Z=2.136,P=0.032 6).Conclusion ALD-ACLF patients with infection tend to have a poor short-term prognosis,and MELD score,NH3,and shock are influencing factors for the short-term prognosis of such patients.The combination of these three factors has a high value in predicting short-term prognosis.

OBJECTIVE: To explore the clinical and genetic characteristics of a child with intellectual development disorder and seizures due to a variant of AP2M1 gene. METHODS: Clinical data of a child with intellectual development disorder and epilepsy who was admitted to the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University in January 2021 were retrospectively analyzed. Peripheral blood samples of the child and his parents were collected for whole exome sequencing. Candidate variant was verified by Sanger sequencing and pathogenicity analysis. The three-dimensional structure of the AP2M1 protein was visualized using Chimera v1.10.1 software. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants from the American College of Medical Genetics and Genomics American College of Medical Genetics (ACMG). With "AP2M1 gene" "epilepsy" "intellectual disability" as the keywords, relevant cases were searched from CNKI, Wanfang Data knowledge service platform and PubMed databases with the search time spanning from the establishment of the database to September 2024. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2020-57). RESULTS: The child was a 8-years-and-6-months-old boy, who could raise his head at 3 months and sit alone at 8 months old. He could not walk alone at 1 year old and underwent 2 months' rehabilitation treatment, and could walk alone and call his parents at 1-and-a-half-years-old. At 4-years-and-10-months-old, he started to have frequent seizures, manifesting as low level of consciousness, body shaking, accompanied by blinking, lasting about a few seconds several times a day and could be relieved. With the treatment of sodium valproate combined with lamotrigine, the convulsions were controlled, but his movement and cognition were lagged behind. DNA sequencing revealed that he has harbored a novel variant of the AP2M1 gene (NM_004068.3) c.508C>T (p.Arg170Trp). Sanger sequencing confirmed that both of his parents were of the wild-type. According to the guidelines from the American College for Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PS2+PS4+PM1+PM2+PP2+PP3). The difference between the wild-type and mutant AP2M1 proteins can be clearly viewed through its three-dimensional structure. Two previous reports have included 5 cases due to the same variant. Common manifestations have included seizures (100%, 5/5), motor retardation (100%, 5/5), intellectual impairment (100%, 5/5), autism spectrum disorder (60%, 3/5), ataxia (100%, 5/5), and special facial features (20%, 1/5). CONCLUSION The c.508C>T (p.Arg170Trp) variant of the AP2M1 gene may underlie the intellectual retardation and seizure in this child.
