The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Objective To investigate the effects of Licorice chalcone A(LCA)on proliferation,migration,invasion and antioxidant capacity of human glioma U87 cells and its mechanism.Methods Glioma U87 cells cultured in vitro were divided into 4 groups,blank control group(conventional culture)and experimental-L,-M,-H groups(5,10,20 μmol·L-1 LC A).Cell proliferation capacity was detected by cell counting kit-8,cell clonogenesis ability was detected by clonogenesis assay,cell migration ability was detected by scratch assay,and cell invasion ability was detected by Transwell assay.Colorimetric assay was used to detect total glutathione(T-GSH),malondialdehyde(MDA)and superoxide dismutase(SOD),and Western blotting was used to detect the protein expression levels of phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt).Results The cell proliferation activities of blank control group and experimental-L,-M,-H groups were(90.20±2.17)％,(79.06±1.57)％,(66.13±2.11)％and(49.52±1.82)％;cell clone formation rates were(76.83±2.30)％,(42.33±2.09)％,(17.71±1.84)％and(12.12±1.97)％;12 h cell mobility rates were(34.92±2.24)％,(27.90±1.89)％,(18.76±1.14)％and(14.87±0.82)％;24 h cell mobility rates were(50.37±2.61)％,(39.43±2.56)％,(21.11±2.33)％and(18.32±2.39)％;the number of perforated cells were 120.39±4.16,79.95±3.83,45.67±3.55 and 18.14±2.85;T-GSH levels were(71.43±2.39),(58.51±2.91),(49.43±2.78)and(35.44±2.76)μmol·L-1;MDA levels were(4.14±0.91),(7.23±1.75),(9.20±1.56)and(11.37±1.90)nmol·mL-1;SOD levels were(41.44±2.10),(35.43±2.91),(28.56±2.32)and(20.62±2.05)U·mg-1;the relative expression levels of p-Akt were 1.27±0.03,1.06±0.02,0.89±0.01 and 0.60±0.02,respectively.The above indexes were statistically significant between experimental-L,-M,-H groups and blank control group(all P＜0.01).Conclusion LCA can inhibit the proliferation,migration,invasion and induce oxidative damage of glioma U87 cells,and its mechanism may be related to the down-regulation of p-Akt protein expression in PI3K/Akt signaling pathway.

Objective To provide clinical practitioners with references for rational and safe usage of cyclophosphamide(CTX)by conducting an in-depth analysis of its adverse drug events(ADE)reported in clinical settings.Methods Based on the Food and Drug Administration(FDA)adverse event reporting system,the online pharmacovigilance tool OpenVigil collected ADE data of CTX from January 1,2013 to March 11,2023.The ADE data mining analysis was performed using the reporting odds ratio(ROR)and Bayesian confidence propagation neural network(BCPNN)methods.Results A total of 8 223 ADE reports met the inclusion criteria,and 422 ADE signals were obtained,involving 21 system organ classification(SOC),of which women(44.12％)accounted for a higher proportion than men(31.02％),the age distribution was mainly in the population 46-65 years old.The involved SOC mainly included infections and invasive diseases,hematologic and lymphatic system diseases,systemic diseases and various reactions at the site of administration,etc.;the ADE signals with a higher number of reports were myelosuppression,disease progression,pyrexia,febrile neutropenia,etc.A total of 18 suspected adverse drug reaction(ADR)not documented in the CTX drug insert were unearthed.Conclusion Clinical practitioners should be alert to ADE signals outside the drug insert,such as neonatal diseases and maternal exposure before pregnancy,methemoglobinemia,etc.,when using cyclophosphamide to improve the safety and effectiveness of clinical treatment.

Objective: To assess the efficacy and safety of combining traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), with Western medicine (WM), compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis (BCET-OP) by meta-analysis. Methods: Thirty-eight randomized controlled trials involving 2170 participants were analyzed. Eight databases were searched for articles published between inception and December 2023. Quality assessment was performed using the Risk of Bias 2 tool. Results: Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density (BMD) (P < .001, mean difference (MD) = 0.07, 95% confidence interval (CI): 0.06 to 0.08), lumbar vertebrae T-score (P = .0005, MD = 0.21, 95%CI: 0.09 to 0.33) and collum femoris BMD (P = .01, MD = 0.10, 95%CI: 0.02 to 0.19). No significant difference was observed between the groups in the collum femoris T-score and estradiol levels. Bone gla-protein levels were significantly increased in the TCM-WM group (P = .0002, MD = 0.52, 95%CI: 0.25 to 0.79). Beta-CrossLaps decreased significantly in the TCM-WM group (P = .0008, MD = −0.10, 95%CI: −0.16 to −0.04). No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase, in procollagen type I N-terminal propeptide, and in the Kupperman index. The visual analog score (VAS) was decreased in the TCM-WM group compared to the WM group (P < .001, MD = −1.40, 95%CI: −1.94 to −0.87). No significant difference in adverse events was observed between the two groups. Conclusion Combining CHM with WM in patients with BCET-OP significantly improved BMD, T-score, and certain bone turnover markers and reduced the VAS score, indicating potential benefits for bone health and related pain. Adverse event analysis revealed no differences between the groups, supporting the feasibility of the combination therapy. However, further research, particularly in diverse populations, is required.

italic>Schisandra chinensis is a traditional Chinese medicine with the functions of reinforcing deficiency, strengthening, and inducing astringency, appliable to treat the chronic cough and deficiency in breath, palpitation, and insomnia, etc. A hybrid mass spectrometry scanning strategy (high-definition data-independent/data-dependent acquisition, HDDIDDA), enabling the ion mobility separation and alternating data-independent acquisition/data-dependent acquisition, was established, which, in combination with in-house library-driven automatic peak annotation workflows facilitated by the UNIFI software, was utilized to systematically characterize the multi-classes of chemical components from S. chinensis. The use of an HSS T3 column (100 mm × 2.1 mm, 1.8 μm), 0.1% formic acid in H₂O-acetonitrile as the mobile phase running at the flow rate of 0.3 mL·min^-1, and column temperature at 35 ℃, could enable good separation of the S. chinensis components within 42 min. HDDIDDA scan in both the positive and negative ion modes was employed for data acquisition. Based on the automatic peak annotation, reference standards comparison, MS² data interpretation, and literature analysis, we were able to identify or tentatively characterize 105 compounds in the S. chinensis decoction, involving 56 terpenoids, 42 lignans, five glycosides, one organic acid, and one flavonoid. HDDIDDA scanning can improve the coverage of data acquisition and improve the accuracy of identification, while CCS prediction analysis provides the possibility to distinguish isomers by the ion mobility technology. The results provide reference for the intelligent material basis research of TCM.

Objective To analyze the economic burden due to healthcare-associated infection(HAI)in low birth weight(LBW)infants,and provide theoretical basis for formulating HAI related policies.Methods The data of LBW infants in a tertiary first-class hospital from January 2018 to December 2022 were retrospectively collected.Propensity score matching method and marginal analysis were adopted to evaluate the economic losses in LBW in-fants and hospitals due to HAI.Results A total of 1 048 LBW infants were included in analysis,124 of whom had HAI,with HAI incidence of 11.8％.A total of 109 pairs were successfully matched using the propensity score matching method.The median length of hospital stay for LBW infants in the HAI group and non-HAI group were 34.0 and 11.0 days,respectively,the length of hospital extended 23 days in LBW infants in the HAI group(P＜0.001).The median hospitalization expenses for LBW infants in HAI group and non-HAI group were 38 067.6 and 12 375.7 Yuan,respectively,the hospitalization expense for LBW infants in HAI group was 25 691.9 Yuan more than non-HAI group(P＜0.001).The major increased expenses were examination,treatment and medication fees.The total hospitalization expenses in different birth weight LBW infants in HAI group were all higher than non-HAI group,and the differences were all statistically significant(all P＜0.05).LBW infants with gestational age＜32 weeks had longer length of hospital stay and higher total hospitalization expense,differences were all statistically significant(all P＜0.05).When the marginal profit ratios were 5％,10％,and 15％,respectively,the economic losses caused by HAI were 371 000 Yuan,742 000 Yuan,and 1 114 000 Yuan,respectively;The ratios of loss-profit and loss-profit to infection coefficient were 0.33 and 2.79,respectively.Conclusion HAI cause significant economic losses to both LBW infants and hospitals.Infants with a birth weight ≤1 000 g and those with a gestational age＜32 weeks are key populations for prevention and control.The lost-profit to infection coefficient can be used to estimate the economic loss of the hospital,timely adjust infection control measures,and reduce the incidence of HAI.

Aim To explore the role of SIRT1/Nrf2 / HO-1 in alleviating the cognitive function impairment by sevoflurane treatment in a mouse model of postoperative cerebral reperfusion. Methods C57BL/6J mice were randomly divided into five groups: sham operation group, hemorrhagic shock reperfusion group, sevoflurane postconditioning group, sevoflurane postcondition-ing + SIRT1 inhibitor group and sevoflurane postconditioning + Nrf2 inhibitor group. Mice were subjected to Morris water maze test after cerebral ischemia reperfusion. The ATP, superoxide dismutase (SOD), ROS and MDA contents in tissue of mice were detected. SIRT1, Nrf2 and HO-1 proteins in tissue were detected by Western blot. Results After hemorrhagic shock, the learning and memory ability of mice was reduced.ATP and SOD concentration in hippocampus was reduced , MDA and ROS concentration increased, and the SIRT, Nrf2 and HO-1 concentration was reduced. Sevoflurane improved the cognitive dysfunction and oxi-dative damage in postoperative mice, and the neuro-protective effect of sevoflurane on hemorrhagic shock and resuscitation mice was weakened followed with SIRT1 and Nrf2 inhibitors. Conclusion Sevoflurane probably alleviates the oxidative reaction damage and cognitive impairment caused by cerebral reperfusion in mice through SIRT1/Nrf2/H0-1 pathway.

Objective To analyse the analgesic effect and possible mechanism of panax notoginseng saponin (PNS) on mouse models of chronic inflammatory pain caused by complete Freund’s adjuvant (CFA). Methods A total of 48 male C57BL/ 6J mice were divided randomly into four groups: normal saline control group (Ctrl), CFA group (CFA), CFA + PNS group (CFA+PNS), CFA + dexamethasone (DEX) group (CFA+DEX). Von Frey filaments were used to detect mechanical pain in mice. Immunohistochemistry was used to detect the number and morphological changes of glial fibrillary acidic protein (GFAP) positive astrocytes. Western blotting was used to detect the expressions of GFAP, nucleotide-binding and oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, interleukin (IL)-1β, and IL-18 in mice’s spinal cord segments in each group. Results Compared with the Ctrl group, mice in the CFA group showed a significant decrease in mechanical pain thresholds at day 1, day 3, day 5, day 7, and day 14. Additionally, there was a significant decrease in NLRP3, ASC, Caspase-1, IL-1β and IL-18 in the spinal cord of the mice. PNS intervention could relieve mechanical pain and down-regulate the expressions of NLRP3, ASC, Caspase-1, IL-1β and IL-18 in the spinal cord of mice, with no significant difference compared with the CFA+DEX group. CFA group mice had significantly more GFAP positive cells in their posterior horns than Ctrl group mice, as measured by immunohistochemistry; PNS intervention decreased the number of GFAP positive cells in the posterior horn of the spinal cord in model mice;DEX had no effect on the number of GFAP positive cells in the dorsal horn of spinal cord. According to Western blotting results, GFAP expression in the spinal cord of the CFA group was significantly more than that of the Ctrl group; PNS intervention significantly reduced GFAP expression in the spinal cord of CFA group mice;DEX had no effect on the expression of GFAP in the posterior horn of spinal cord. Conclusion PNS has a good alleviating effect on inflammatory pain, and its mechanism may be related to inhibition of astrocyte activation and NLRP3 inflammasome activation.
