OBJECTIVE To compare the efficacy and safety of different daily doses of aspirin in the prevention of preeclampsia （PE）. METHODS The case-control studies and prospective randomized controlled trials on aspirin with daily dose ≥ 100 mg （trial group） vs. ＜100 mg （control group） in the prevention of PE were retrieved from PubMed， Medline， Embase， the Cochrane Library， CNKI， China Biomedical Literatue Database and Wanfang Data from base-building to January 2025. After literature screening， data extraction and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 11 literatures were included， involving 3 052 pregnant women. Meta-analysis showed the incidence of PE [RR＝0.63， 95%CI （0.53，0.76）， P＜0.000 01]， gestational hypertension [RR＝0.69， 95%CI （0.50，0.94），P＝0.02]， preterm birth [RR＝0.56， 95%CI （0.47，0.66）， P＜0.000 01]， and intrauterine growth retardation [RR＝0.73，95%CI （0.61，0.87），P＝0.000 5] in trial groups were significantly lower than control group. The incidence of postpartum hemorrhage between the two groups had no statistically significant difference [RR＝1.17， 95%CI （0.90，1.53），P＝0.25]. Subgroup analysis showed that the incidence of PE in Chinese pregnant women taking 150 mg of aspirin was significantly higher than taking 100 mg of aspirin [RR＝3.40， 95%CI （1.29， 8.93）， P＝0.01]； but there was no significant difference between the two groups in the incidences of postpartum hemorrhage， preterm birth （P＞0.05）. CONCLUSIONS Aspirin with daily dose ≥100 mg is more effective in preventing PE than daily dose ＜100 mg， with lower rates of gestational hypertension， preterm birth， and intrauterine growth retardation. It does not increase the risk of postpartum hemorrhage. For pregnant women in China， daily dose 100 mg of aspirin may be more effective in preventing PE than 150 mg.

Pulmonary disease is one of the major threats to human health. However, the current clinical treatment drugs for lung diseases generally have problems such as low lung delivery efficiency, fast clearance rate and obvious toxic side effects. Recently, membrane biomimetic nanocarriers have attracted more and more attention. Due to their advantages of high targeting, long cycle time, good biocompatibility and strong immune escape ability, membrane biomimetic nanocarriers have become a major research hotspot in targeted therapy of lung diseases. In this review, we discuss the main preparation methods of membrane biomimetic nanoparticles, the characteristics of membrane biomimetic nanocarriers from different cell sources and their application in the targeted therapy of lung diseases. At the same time, according to the characteristics of different membranes, the shortcomings, current technical limitations and future prospects are discussed. This review is expected to provide references for the design of membrane biomimetic nanocarriers and their potential applications in the treatment of lung diseases.

ObjectiveTo investigate the antidepressant effect of Sinisan （SNS） by regulating glycogen aynthase kinase-3β （GSK-3β）/tumor necrosis factor alpha-induced protein 3（A20）/CCAAT enhancer binding protein β（C/EBPβ） to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group， model group， fluoxetine group （5.0 mg·kg^-1）， low-dose Sinisan group （4.9 g·kg^-1）， medium-dose Sinisan group （9.8 g·kg^-1）， and high-dose Sinisan group （19.6 g·kg^-1）， with 12 mice in each group. After one week of adaptive feeding， chronic unpredictable mild stress （CUMS） was performed to establish the depression model. In the fifth week， drug treatment was conducted for four weeks. In the ninth week， behavioral tests were performed， including sucrose preference test （SPT）， open field test （OPT）， elevated plus maze （EPM） test， and forced swimming test （FST）. Western blot was used to detect the expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， nitric oxide synthase （iNOS）， GSK-3β， A20， and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 （Iba1） and cluster of differentiation 68 （CD68） in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS， compared with the normal group， the mice in the model group had a significantly reduced sucrose preference rate （P<0.01）， and the activity in the central area of the OPT was significantly reduced （P<0.01）. The activity in the open arm area of the EPM test was significantly reduced （P<0.05）， and the immobility time of FST was increased （P<0.01）. The expression levels of inflammatory proteins IL-1β， IL-6， and iNOS were increased （P<0.01）， and the fluorescence co-localization index of Iba1 and CD68 was increased （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ were significantly increased （P<0.05， P<0.01）. After four weeks of SNS intervention， compared with the model group， the mice in the SNS group had significantly increased sucrose preference rate （P<0.01）， significantly increased activities in the central area and the open arm area in the OPT and the EPM test （P<0.05）， and significantly reduced immobility time in the FST （P< 0.01）. The protein expression levels of IL-1β， IL-6， and iNOS were significantly decreased （P<0.05）， and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased （P<0.01）， and that of A20 was significantly increased （P<0.01）. ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

OBJECTIVE To evaluate the medication adherence of patients with hypertension in medication consultation clinics， and to analyze its influencing factors. METHODS The data of 389 patients who visited the medication consultation clinics of our hospital from June 2021 to June 2023 were collected. Univariate and multivariate Logistic regression analysis were used to analyze the related factors affecting medication adherence of hypertensive patients or those receiving different types of drugs. RESULTS Among 389 patients with hypertension， 302 cases （77.63%） had good adherence. Multivariate Logistic analysis showed that higher education level [corrected OR＝2.25， 95%CI （1.29， 3.93）， P＝0.004] was positively correlated with medication adherence， average blood pressure level [corrected OR＝0.19， 95%CI （0.10， 0.37）， P＜0.001]， without complication [corrected OR＝0.47， 95%CI（0.26，0.84），P＝0.010] and antihypertensive drug regimen being free dose combination [corrected OR＝0.27，95%CI（0.15， 0.47）， P＜0.001] were negatively correlated with adherence. Results of univariate Logistic regression analysis showed that patients who used β-receptor blocking agents [OR＝1.65，95%CI（1.06，2.57），P＝0.027]， calcium channel blockers [OR＝2.13，95%CI（1.33， 3.42），P＝0.002] and agents acting on the renin-angiotensin system [OR＝2.04，95%CI（1.29，3.22），P＝0.002] had good medication adherence. CONCLUSIONS The medication adherence of hypertension patients needs to be improved. Hypertension patients with higher education level， lower average blood pressure level， complications and fixed-dose combination regimen and those who use agents acting on the renin-angiotensin system， calcium channel blockers and β-receptor blocking agents may have better medication adherence.

ObjectiveThe traditional Chinese medicine Strychnos nux-vomica L. (SN) has the clinical effect of reducing swelling and relieving pain; however, SN is toxic due to its alkaloid components. Little is known about the endogenous metabolic changes induced by SN toxicity in rats and their potential effects on the metabolic dysregulation of intestinal microbiota. Therefore, toxicological investigation of SN is of great significance to its safety assessment. In this study, the toxic mechanisms of SN were explored using a combination of metabonomics and 16S rRNA gene sequencing. MethodsThe toxic dose, intensity, and target organ of SN were determined in rats using acute, cumulative, and subacute toxicity tests. UHPLC-MS was used to analyze the serum, liver, and renal samples of rats after intragastric SN administration. The decision tree and K Nearest Neighbor (KNN) model were established based on the bootstrap aggregation (bagging) algorithm to classify the omics data. After samples were extracted from rat feces, the high-throughput sequencing platform was used to analyze the 16S rRNA V3-V4 region of bacteria. ResultsThe bagging algorithm improved the accuracy of sample classification. Twelve biomarkers were identified, where their metabolic dysregulation may be responsible for SN toxicity in vivo. Several types of bacteria such as Bacteroidetes, Anaerostipes, Oscillospira and Bilophila, were demonstrated to be closely related to physiological indices of renal and liver function, indicating that SN-induced liver and kidney damage may be related to the disturbance of these intestinal bacteria. ConclusionThe toxicity mechanism of SN was revealed in vivo, which provides a scientific basis for the safe and rational clinical use of SN.

Objective:To evaluate the diagnostic performance of radiomics model based on contrast-enhanced ultrasound(CEUS) in predicting pathological complete response(pCR) after neoadjuvant chemoradiotherapy(nCRT) in patients with locally advanced rectal cancer(LARC).Methods:One hundred and six patients with LARC who underwent total mesorectal excision after nCRT between April 2018 and April 2023 in the First Affiliated Hospital of Guangxi Medical University were retrospectively included, the patients were randomly divided into a training set of 63(14 pCR patients) and a validation set of 43(12 pCR patients) in a 6∶4 ratios. Radiomics features were extracted from the tumors′ region of interest of CEUS images based on PyRadiomics. Intra-class correlation coefficient(ICC), Mann-Whitney U test, and least absolute shrinkage and selection operator(LASSO) algorithms were used to reduce features dimension. Finally, 7 radiomics features relevanted to pCR were selected to construct an ultrasomics model using elastic network regression, based on the R language. A combined model was constructed by jointing clinical feature. The performance of the models was assessed with the area under the ROC curve(AUC). Results:The AUC of the ultrasomics model and the combined model was 0.695(95% CI=0.532-0.859) and 0.726(95% CI=0.584-0.868) respectively in the training set. The AUC of the ultrasomics model and the combined model was 0.763(95% CI=0.625-0.902) and 0.790(95% CI=0.653-0.928) respectively in the validation set. Both univariate and multivariate Logistic regression analyses showed that CA199( P<0.05) and ultrasomics score( P<0.001) could be an independent predictor of pCR after nCRT in patients with LARC. Conclusions:The CEUS-based radiomics scores has certain predictive value for whether LARC patients achieve pCR after nCRT, and may provide a non-invasive imaging biomarker for predicting LARC patients achieve pCR after nCRT.

Wuhutang is the 51st Chinese medicine prescription of Han ethnic group on in the catalogue of ancient classical prescriptions （the second batch） ，which originated from Renzhai' Straight Diections Prescriptions （《仁斋直指方》） by YANG Shiying in the Song dynasty，it is composed of 5 medicines， including Ephedrae Herba，Armeniacae Semen Amarum， Glycyrrhizae Radix et Rhizoma， tea and Gypsum Fibrosum. It treats shortness of breath and phlegm. Following the principle of textual research on the key information of ancient classical famous prescriptions， the author collected and recorded the ancient books of traditional Chinese medicine of Wuhutang with the method of Bibliometrics， and screened out 53 valid data， involving 41 ancient books. Based on the historical evolution， drug composition， main treatment of disease and syndrome， drug dosage， method of preparation and usage， drug origin and processing， the author conducted a dig and a systematic study of Wuhutang. The results show that：in the later generations， besides inheriting the original prescription， the composition of medicine was added or subtracted， and the frequency of addition of Mori Cortex was the most；in the treatment of disease and syndrome， most of them inherited the original prescription mainly treating asthma syndrome， also see in the treatment of asthma， cough and other lung disease， in the drug dosage and method of use ， it is suggested to inherit the original prescription， the dosage of each medicine is： Ephedrae Herba 2.89 g， Armeniacae Semen Amarum 4.13 g， Glycyrrhizae Radix et Rhizoma 1.65 g， tea 3.30 g， Gypsum Fibrosum 6.20 g， decoction， take warm clothes before eating；on the source of medcine，ephedra is made from the dried herbaceous stems of Ephedra sinica （Ephedraceae），bitter almond is made from the dried and mature seeds of Prunus armeniaca （Rosaceae），Licorice is made from the dried roots and rhizomes of Glycyrrhiza uralensis（Legumes）， tea is made from the buds leaves of Camellia sinensis（Camellia），plaster is made from Gypsum Fibrosum of sulfate mineral gypsum family. At the same time， we collected and sorted the modern clinical application literature of Wuhutang， and obtained 73 effective literatures， all of which are for the treatment of respiratory system diseases， especially for children's pneumonia and asthma， and mostly belong to"phlegm-heat obstructing the lung syndrome". Through the analysis and study of ancient books and modern applied literature， the historical evolution and prescription evolution of Wuhutang are clarified， and its key information is determined， in order to provide more accurate reference for the research and development of the classic Wuhutang and the rational addition and subtraction of the application.
