OBJECTIVE To compare the antihypertensive efficacy of sacubitril/valsartan versus benazepril in patients with perimenopausal hypertension， as well as their impacts on ventricular remodeling and inflammatory fibrosis. METHODS A total of 206 perimenopausal hypertensive patients in our hospital from January 1， 2023 to December 30， 2024 were retrospectively included.These patients were enrolled and divided into benazepril group （105 cases） and sacubitril/valsartan group （101 cases）. Benazepril group received Benazepril hydrochloride tablet， and sacubitril/valsartan group received Sacubitril valsartan sodium tablet. All patients were treated for 6 months. The blood pressure（systolic blood pressure and diastolic blood pressure） and blood pressure control status before and after treatment， echocardiographic indicators （left ventricular ejection fraction， left ventricular mass index， relative wall thickness， and early-diastolic peak transmitral flow velocity/early-diastolic peak velocity of the mitral annulus）， inflammatory fibrosis related indicators（high-sensitivity C-reactive protein，ratio of monocytes to lymphocytes，and ratio of neutrophils to lymphocytes）， as well as the occurrence of adverse reactions（hypotension，hyperkalemia，and angioedema） were observed in both groups before and after treatment. RESULTS The blood pressure control rate was significantly higher in the sacubitril/valsartan group than in benazepril group （ P ＜0.05）. After treatment， the blood pressure， echocardiographic indicators（except for left ventricular ejection fraction） ，and inflammatory fibrosis related indicators were significantly lower than those before treatment within the same group， and the sacubitril/valsartan group were significantly lower than the benazepril group （ P ＜0.05）. There were no statistically significant differences in the incidence of hypotension， hyperkalemia， angioedema， and overall adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared with benazepril， sacubitril/valsartan provides superior blood-pressure control， reverses ventricular remodeling， attenuates inflammatory fibrosis in perimenopausal hypertensive patients， while maintaining a similar safety profile.

In this study, araucarene diterpenes, characterized by a pimarene skeleton with a variably oxidized side chain at C-13, were investigated. A total of 16 araucarene diterpenoids and their derivatives were isolated from the woods of Agathis dammara, including 11 previously unreported compounds: dammaradione (1), dammarones D-G (2, 5, 14, 15), dammaric acids B-F (8-12), and dammarol (16). The structures of these new compounds were elucidated using high-resolution electrospray ionization mass spectroscopy (HR-ESI-MS) and one-dimensional/two-dimensional (1D/2D) nuclear magnetic resonance (NMR), while their absolute configurations were determined through the electronic circular dichroism (ECD) exciton chirality method and Snatzke's method. The hypoglycemic activity of all isolated compounds was evaluated using a transgenic zebrafish model, and a structure-activity relationship (SAR) analysis was conducted. Araucarone (3) and dammaric acid C (9), serving as representative compounds, demonstrated significant hypoglycemic effects on zebrafish. The primary mechanism involves the promotion of pancreatic β cell regeneration and glucose uptake. Specifically, these compounds enhance the differentiation of pancreatic endocrine precursor cells (PEP cells) into β cells in zebrafish.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

Objective:To compare the efficacy of drug-coated balloon (DCB) angioplasty and self-expanding stenting in symptomatic middle cerebral artery stenosis (MCAS).Methods:A retrospective study was performed. Patients with symptomatic MCAS admitted to Department of Cerebrovascular Diseases, Interventional Center, He'nan Provincial People's Hospital from January 2020 to December 2022 were chosen from their prospective study database. They were divided into a DCB group and a stent group based on approaches. Baseline data differences between the two groups were eliminated using 1: 1 propensity score matching (PSM). Then, the technical success rate, immediate restenosis rate, and 6-month restenosis rate, and clinical outcomes within 30 days and 1 year of procedure were compared between the two groups.Results:After PSM, 58 patients were included, with 29 in the stent group and 29 in the DCB group. Technical success rate was 93.1% (27/29) in the DCB group and 96.6% (28/29) in the stent group, without significant difference ( P>0.05). The immediate restenosis rate was 6.9% (2/29) in the DCB group and 3.4% (1/29) in the stent group, without significant difference ( P>0.05). In terms of safety, no stroke or death events were noted in the two groups within 30 days of procedure; ischemic stroke incidence in the offending vessel areas within 1 year of procedure in the DCB group and stent group was 3.7% (1/27) and 11.5% (3/26), without significant difference ( P>0.05); no hemorrhagic stroke or death were noted in the two groups within 1 year of procedure. In terms of efficacy, the modified Rankin scale score of the two groups was both 0 (0, 0) at 1 year of follow-up, without significant difference ( P>0.05); 46 patients in the DCB group and stent group had imaging followe-up for 6 months: the restenosis rate was 8.0% (2/25) and 23.8% (5/21), respectively, without significant difference ( P>0.05). Conclusion:DCB angioplasty is comparable in efficacy and safety with self-expanding stenting in symptomatic MCAS.
