Objectives:The purpose of this cross-sectional study was to determine the predictive value of measuring awake blood pressure(BP)at different time points on nocturnal hypertension by ambulatory blood pressure monitoring(ABPM)device in patients with hypertension. Methods:A total of 204 consecutive hypertensive outpatients seeking medical care at the First Affiliated Hospital of Fujian Medical University from April 2023 to July 2023 were enrolled.We measured office BP and out-office BP.Out-office BP include evening BP,bedtime BP,morning BP and mean morning BP which were measured by ABPM device and BP daily record.Nocturnal hypertension was defined by the mean nocturnal systolic blood pressure≥120 mmHg(1 mmHg=0.133 kPa).ROC curve analyses of different awake blood pressure was established to identify significant correlates to nocturnal hypertension.The serial test was also performed.The value of the two indexes in predicting nocturnal hypertension was compared.The predictors of nocturnal hypertension were evaluated by multivariate analysis. Results:Of the 204 subjects,104(51.0%)had nocturnal hypertension.The repeated measures analysis of variance(ANOVA)showed that mean nighttime systolic BP and bedtime systolic BP were similar(P=0.641).Nocturnal hypertension was present in 75.7%(84/111)of patients with bedtime systolic BP≥120 mmHg,in 94.2%(49/52)of patients with bedtime systolic BP≥135 mmHg and in 88.2%(75/85)of patients with mean morning systolic BP≥135 mmHg.ROC curve analyses showed that the diagnostic accuracy of mean morning systolic BP(AUC 0.903,P<0.05)for subjects with nocturnal hypertension was significantly superior to that of office systolic BP,evening systolic BP,bedtime systolic BP,morning systolic BP.Multivariate logistic regression analysis revealed that mean morning systolic BP and bedtime systolic BP were significantly associated with a higher risk of nocturnal hypertension(P<0.05).ROC curve analyses of predicted probability of bedtime systolic BP and mean morning systolic BP showed higher diagnostic accuracy(AUC 0.929,P<0.05).The serial test showed that nocturnal hypertension was present in 98.0%(49/50)of patients with bedtime systolic BP≥130 mmHg and mean morning systolic BP≥135 mmHg. Conclusions:Mean morning BP and bedtime BP are significant correlates of nocturnal hypertension in patients with hypertension,and combined mean morning BP with bedtime BP showed higher diagnostic accuracy,which might used for predicting nocturnal hypertension with high efficiency.

Objective To analyze the pathogenic composition of hand, foot and mouth disease (HFMD) cases and the antibody level of enterovirus 71 (EV-A71) in healthy people in Xi'an in 2022, so as to provide evidence for the prevention and control of HFMD. Methods Anal swabs or stool specimens of HFMD cases were collected. RT-PCR was used to detect enterovirus (EV) and serotype was identified. Enzyme-linked immunosorbent assay (ELISA) was used to detect EV-A71 IgG antibody levels in healthy people. Results A total of 172 positive cases were detected from 274 HFMD clinical specimens with a total detection rate of 62.77%, including 1 case of EV-A71 (0.58%), 95 cases of CV-A16 (55.23%), 64 cases of CV-A6 (37.21%), and 1 case of CV-A10(0.58%). CV-A16 was the dominant pathogen in spring and summer, and CV-A6 was the dominant pathogen in autumn and winter(χ2= 64.376,P<0.001). The age of HFMD cases caused by CV-A16 was older than the cases caused by CV-A6(t = 2.709,P = 0.007). The positive rate of EV-A71 IgG antibodies in healthy people was 36.92% (168/455). The positive rate of EV-A71 IgG antibodies in men (32.35%) was lower than that in women (43.72%), and the difference was statistically significant (χ2= 6.605 , P = 0.014). The positive rate of EV-A71 IgG antibodies in people of all ages ranged from 21.95% to 54.78%, and the difference was statistically significant (χ2= 27.623 , P<0.001). Conclusion The main pathogens of hand, foot and mouth disease in Xi'an in 2022 are CV-A16 and CV-A6 . The positive rate of EV-A71 IgG antibodies in children under 5 years old is low , and EV-A71 vaccination should be strengthened.

ObjectiveTo explore new targets and herbal medicines of total ginsenosides in ameliorating alcoholic hepatitis (AH) by data mining and experimental validation and to provide new directions for the clinical treatment of AH. MethodGSE28619 was selected as the test set from the GEO database and GSE83148 and GSE103580 were selected as the validation sets. The limma package and weighted gene co-expression network analysis (WGCNA) were employed to identify the AH-related differentially expressed genes and modular genes, and Venny was used to extract the common genes. The protein-protein interaction (PPI) network was constructed and the enrichment analysis was carried out. The hub genes were further screened and evaluated for their diagnostic value. After validation with the datasets, new potential targets of AH and traditional Chinese medicine were predicted. Molecular docking between the targets and active ingredients of traditional Chinese medicine was performed, and the results were validated by experiments. Eight out of 48 SD rats were randomly selected into a blank group and received an equal amount of normal saline. The rest rats were subjected to modeling with ethanol by gavage and then randomized into low- (10 mg·kg-1), medium- (20 mg·kg-1), and high-dose (40 mg·kg-1) total ginsenosides, model, and positive control (metadoxine, 117 mg·kg-1) groups. After 3 weeks of gavage, serum samples were collected for the measurement of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, and liver samples were collected for hematoxylin-eosin (HE) staining. Western blot and Real-time PCR were employed to determine the protein and mRNA levels, respectively, of potential targets in the liver tissue. ResultData mining predicted the potential genes: Proto-oncogene FOS and collagen type Ⅰ alpha 2 (COL1A2). Experimental validation showed that the liver injury was alleviated after drug administration compared with that after modeling. The serum AST and ALT levels were reduced after drug administration. The protein and mRNA levels of FOS were significantly up-regulated, while those of COL1A2 were down-regulated after drug administration. ConclusionTotal ginsenosides ameliorate HA via FOS and COL1A2.

OBJECTIVE
To explore the mechanism of Baihe Dihuang decoction in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking and animal experiment.
METHODS
TCMSP were used to predict the active components and targets of Baihe Dihuang decoction and disease-related targets were collected from GeneCards, OMIM and DRUGBANK databases, respectively. Target protein interactions were analyzed with STRING database and biological function and pathway were analyzed with Metascape database. Lastly relevant results were analyzed with Cytoscape 3.8.0. AutoDock vina software was used for molecular docking to analyze the binding energy of the active components and key targets of Baihe Dihuang decoction. PyMOL software were used to visualize the optimal docking results. ICR male mice were randomly divided into control group, model group, Rolipram group, low, medium and high dose group of Baihe Dihuang decoction. After 14 days of administration, the neurobehavioral scores of mice in each group were collected, and the expression of related proteins in brain tissue was detected, ELISA and Western blotting were used to detect the expression of the key protein cAMP, PKA, p-CREB and BDNF. At last, the adverse reaction of Baihe Dihuang decoction was observed by vomiting experiment.
RESULTS
A total of 13 active components and 39 key targets were collected from network pharmacology. The docking results showed that the first 10 core targets all performed well and their effects were closely related to PRKACA. Compared with the control group, the model group mice's recognition rate of new objects and the spontaneous alternation reaction rate were significantly reduced, the escape latency was significantly prolonged, and the target quadrant stay time, the number of crossing platforms were significantly reduced; cAMP, PKA, p-CREB and BDNF in the hippocampus of mice was significantly decreased. Baihe Dihuang decoction could reverse the behavior of AD mice and the expression of cAMP, PKA, p-CREB and BDNF. In the vomiting experiment, the anesthesia recovery time of the Rolipram group was significantly prolonged, while that of the Baihe Dihuang decoction group was not significantly affected.
CONCLUSION
The mechanism of Baihe Dihuang decoction in the treatment of AD may be related to its influence on cAMP-PKA and regulation of cAMP-PKA-CREB-BDNF signal pathway, and the adverse reactions are milder than those of clopramide.

Objective:To investigate the genetic and evolutionary characteristics of hemagglutinin (HA) and neuraminidase (NA) genes of influenza B/Victoria (BV) virus in Xi′an city from 2019 to 2023.Methods:Twenty-five BV strains isolated from the Xi′an influenza surveillance network laboratory between 2019 and 2023 were collected. The HA and NA genes were sequenced using MiniSeq high-throughput sequencing platform. An evolutionary tree was constructed using bioinformatics software to analyze homology and mutation sites, and to predict N-glycosylation sites online. The antigenicity of the strains was analyzed through hemagglutination inhibition tests.Results:The BV influenza in Xi′an exhibited a distinct seasonal transmission pattern from 2019 to 2023, with peak prevalence occurring during the winter and spring seasons. The evolutionary analysis of the HA genes shows that the strains from Xi′an in 2019 belong to the V1A.3 branch, and the strains from 2021 to 2023 belong to the V1A.3a.2 branch. Analysis of antigenic sites showed that there were variations in 6 sites of 3 antigenic determinants in the HA proteins of the BV strains from 2021-2022 compared to 2019, and 2 sites of 1 antigenic determinant changed in the HA proteins in 2023 compared to 2021-2022. The evolutionary analysis of the NA genes indicates that the BV strains from Xi′an in 2019 belong to the A. 1.1 branch. By 2021 and 2022, it had evolved into the A. 1.2 clade, and by 2023, it had further evolved into the B clade and its derivatives, with no strains showing mutations associated with resistance to NA inhibitors. Antigenic analysis indicated that the majority of BV strains in Xi′an were similar to the strains included in the vaccine composition. Furthermore, glycosylation analysis showed that the potential N-glycosylation sites in the HA proteins of BV strains from 2021-2023 were reduced by one compared to those from 2019, and only a few strains from 2023 displayed alterations in the potential N-glycosylation sites of the NA proteins.Conclusions:The HA and NA genes of the BV strains from 2019 to 2023 are continuously mutating and evolving into new branches. Since 2021, V1A.3a.2 has become the dominant evolutionary branch of the HA genes, while the evolutionary branches of the NA genes from 2019 to 2023 have been continuously changing.

Long-term inflammation will develop into chronic inflammation and become inflammatory diseases.Antibiotics are commonly used in clinical practice to treat inflammatory diseases.But patients are prone to drug resistance.So we need to find new treatment.Chlorogenic acid is an organic compound extracted from honeysuckle and other plants.Its anti-inflammatory activity is strong,and it has a significant anti-inflammatory effect on inflammatory diseases in various systems.It has been shown that chlorogenic acid can regulate inflammation-related signaling pathways,such as nuclear factor κB(NF-κB)canonical signaling pathway,NF-κB atypical signaling pathway,nuclear factor-erythroid 2-related factor 2(Nrf2)canonical signaling pathway,and Nrf2 atypical signaling pathway,etc.It can up-regulate the expression of anti-inflammatory cytokines such as interleukin(IL)-4,IL-10,IL-13 and down-regulate the expression of pro-inflammatory cytokine such as IL-1β,IL-6,and IL-8.Although chlorogenic acid has a strong anti-inflammatory effect,but clinical trials and application still face many difficulties.In the future,the anti-inflammatory molecular mechanism of chlorogenic acid should be further studied to explore its clinical application value and improve new ideas for the treatment of inflammatory diseases.
