ObjectiveTo investigate the prevalence of coronary microvascular dysfunction （CMD） during the perioperative period of elective percutaneous coronary intervention （PCI） and the incidence of deterioration in coronary microvascular function using angiography-derived microcirculatory resistance （AMR）， and to explore the influencing factors associated with PCI-related coronary microvascular injury. MethodsPatients who underwent elective PCI on the left anterior descending coronary artery at Beijing Hospital of Traditional Chinese Medicine， Capital Medical University， from January 1， 2021 to December 31， 2024 were retrospectively enrolled. AMR values of the target vessel before and after PCI were calculated to evaluate the prevalence of postoperative CMD and the incidence of microvascular functional deterioration. Multivariate analysis was performed to explore the influencing factors associated with coronary microvascular injury during the periprocedural period of PCI. ResultsA total of 204 patients were finally included. Postoperative AMR of the target vessel were significantly higher than preoperative values （P＜0.001）. The prevalence of CMD was 31.86% （65/204）， and the incidence of microvascular functional deterioration was 69.61% （142/204）. In-stent restenosis （P = 0.004） and post-balloon dilation （P = 0.002） were risk factors for CMD. Traditional Chinese medicine （TCM） syndrome elements phlegm-turbidity （P = 0.004） and blood stasis （P = 0.013）， a higher diameter stenosis rate of the target lesion （P = 0.006）， larger stent/balloon diameter （P = 0.009）， and a greater number of balloon inflations （P = 0.029） were risk factors for microvascular functional deterioration. Preoperative use of Chinese herbal decoctions with actions of resolving phlegm and activating blood （P = 0.014） was a protective factor against microvascular functional deterioration， while intraoperative use of Kuanxiong Aerosol （宽胸气雾剂） was a protective factor against both CMD （P = 0.007） and microvascular functional deterioration （P = 0.030）. ConclusionCMD and microvascular functional deterioration are relatively common during the perio-perative period of elective PCI. Target lesion characteristics， PCI procedural features， and the TCM syndrome elements of phlegm-turbidity and blood stasis are associated with an increased risk of coronary microvascular injury during the perioperative period， whereas TCM treatment may reduce this risk.

Objective To observe the value of MRI quantified uterine indictors in late pregnancy for predicting uterine inertia in delivery.Methods A total of 182 pregnant women were retrospectively collected and were divided into uterine inertia group(inertia group,n=67)and non-uterine inertia group(non-inertia group,n=115)based on delivery or cesarean section records.MRI quantified uterine indicators were compared between groups,and those being statistically different were included to build a multivariate logistic regression model for predicting uterine inertia in delivery.The predictive performance of this model was evaluated using receiver operating characteristic(ROC)curve and the area under the curve(AUC).Results The inertia group had more previous uterine surgeries,also higher proportion of in vitro fertilization and embryo transfer(IVF-ET)and cesarean sections compared to the non-inertia group(all P＜0.05).In late pregnancy,the longitudinal diameter of the uterus,cervical length and the thickness of the myometrium at the placental attachment site in inertia group were larger than those in non-inertia group(all P＜0.05).Increased times of previous uterine surgeries,undergoing IVF-ET,as well as increased longitudinal diameter of the uterus and cervical length in late pregnancy were all independent predictors of uterine inertia in delivery(all P＜0.05).AUC of the multivariate logistic regression model established based on the above factors for predicting uterine inertia in delivery was 0.733.Conclusion MRI quantified uterine indictors in late pregnancy could be used to predict uterine inertia in delivery.

ObjectiveTo systematically evaluate the efficacy and safety of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines in the treatment of coronary microvascular disease （CMD）. MethodsPubMed， Cochrane Library， CNKI， Wanfang Data， and VIP were searched for the randomized controlled trials （RCTs） on the treatment of CMD with Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis with the time interval from inception to December 31， 2023. The primary outcome indicators included the index of microcirculatory resistance （IMR）， coronary flow reserve （CFR）， and corrected TIMI flow frame count （cTFC）. The secondary outcome indicators included symptomatic efficacy， left ventricular ejection fraction （LVEF）， hypersensitive C-reactive protein （hs-CRP）， nitric oxide （NO）， and adverse events. Cochrane risk-of-bias assessment tool 2.0 （RoB 2.0） and Stata 17.0 were used for literature quality evaluation and meta-analysis of the included RCTs. The Grading of Recommendations， Assessment， Development and Evaluation （GRADE） was used to evaluate the quality of evidence. ResultsA total of 36 RCTs were included in this study， involving 3 029 patients. Compared with conventional Western medicine alone， the combined use of Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis and Western medicine reduced the IMR ［mean difference （MD）=-5.93， 95% confidence interval （95%CI） ［-8.73，-3.14］， n=382， P<0.01］， cTFC （MD=-9.35， 95%CI ［-13.94，-4.76］， n=618， P<0.01）， and hs-CRP ［standard mean difference （SMD）=-1.50， 95%CI ［-1.90，-1.11］， n=1 483， P<0.01］， improved the CFR （SMD=1.14， 95%CI ［0.08，2.19］， n=304， P=0.03）， symptomatic efficacy ［relative risk （RR）=1.36， 95%CI ［1.21，1.53］， n=756， P<0.01］， LVEF （MD=4.39， 95%CI ［2.31，6.47］， n=533， P<0.01）， and NO （SMD=3.16， 95%CI ［2.07，4.25］， n=946， P<0.01） of CMD patients. In terms of safety， the combined therapy reduced the occurrence of adverse events in CMD patients （RR=0.49， 95%CI ［0.29，0.82］， n=591， P=0.01）. GRADE showed moderate quality evidence for adverse events， low quality evidence for cTFC， symptomatic efficacy， LVEF， and NO， and very low quality evidence for IMR， CFR， and hs-CRP. ConclusionBased on microcirculatory function indicators， the combined use of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines and Western medicine may further improve the coronary microvascular function in CMD patients with good safety. The above conclusions remain to be verified with high-quality clinical trials.

Objective To observe the value of placental MRI morphological indicators for diagnosing placenta accreta spectrum(PAS).Methods Totally 214 pregnant women who underwent prenatal placental MR examination were retrospectively enrolled and divided into PAS group(n=110)and non PAS group(n=104)based on the presence of PAS or not,also into PAS subgroup and non PAS subgroup during different weeks of pregnancy.Clinical and MRI data were compared between groups and subgroups,and the value of placental MRI morphological indicators for diagnosing PAS was analyzed.Results Significant differences of pregnant women's age,gestational week at MR examination,delivery gestational week,times of pregnancies,deliveries,cesarean sections,miscarriages and uterine clearances,as well as proportion of placenta praevia were found between groups(all P＜0.05).During 28-32 weeks and 32+1-36 weeks of pregnancy,significant differences of placental diameter,area and volume were found between subgroups(all P＜0.05),while no significant differences of placental MRI morphological indicators at gestational age＞36 weeks was found between subgroups(all P＞0.05).The area under the curve(AUC)of placental diameter,area and volume for diagnosing PAS at 28-32 weeks of pregnancy was 0.749,0.729 and 0.791,respectively,at 32+1-36 weeks was 0.718,0.686 and 0.614,respectively,being not significantly different(all P＞0.05).Conclusion Placental MRI morphological indicators at 28-36 weeks of pregnancy were helpful for diagnosing PAS.

Objective:To explore the effective components and potential mechanisms of Xiefei Lishui Prescription in the treatment of heart failure.Methods:Ultra high-performance liquid chromatography tandem four stage rod time of flight mass spectrometry (UPLC-Q-TOF-MS) technology was used to analyze and identify the active components of Xiefei Lishui Prescription. Drug targets were predicted through the Swiss Target Prediction database, and disease targets were collected from Gene Cards, Dis GENET, and TTD databases. The intersection of drug targets and disease targets was screened using a STRING database for protein interaction to identify core targets. The core targets were included in the DAVID database for GO enrichment and KEGG analysis. Finally, molecular docking validation was performed between the drug components and the corresponding core targets.Results:The results identified 10 active components of Xiefei Lishui Prescription, and 8 potential active components were screened using network pharmacology for the treatment of heart failure with Xiefei Lishui Prescription, corresponding to 160 related action targets. A total of 1 305 disease-related targets were collected, and a total of 51 targets ad 17 core targets were included in the string database for protein interaction analysis. GO functional enrichment and KEGG analysis indicated that the mechanism of Xiefei Lishui Prescription in treating heart failure may be related to pathways such as protein binding, ATP binding, and negative regulation of the VEGF signaling pathway and T cell receptor pathway during apoptosis. The molecular docking results showed that baicalin exhibited good binding activity with ESR1, sorghum isoflavones with ESR1, and quercetin with AKT1, EGFR, IL2, and ABCB1.Conclusion:Xiefei Lishui Prescription may exert therapeutic effects on heart failure through multiple pathways by targeting ESR1, AKT1, EGFR, and other targets.

Myocardial fibrosis is characterized by pathological remodeling of extracellular matrix,which is a common pathological change during the development of various cardiovascular diseases.Qi transformation dysfunction in the zang-fu organs,subtle substance accumulation,and endogenous turbid evil production lead to the occurrence of diseases.The theory of turbid blood is widely used to elucidate the pathological changes of diseases and guide the prevention and treatment.Turbid blood,as a special pathogenic factor and pathological product,plays a crucial role in the oxidative stress process of myocardial fibrosis.Qi deficiency of the heart and spleen,stagnation of turbid blood,impaired blood circulation in the heart,and the inability to maintain the oxidative-reductive system balance of myocardial cells are the root causes of disease onset.Accumulation of turbid blood,intermingled phlegm and blood stasis,blockage of heart vessels,and accumulation of metabolic waste products contribute to disease progression.Prolonged turbidity accumulation leads to cardiac enlargement,scattered mental state,and pathological remodeling of the extracellular matrix,indicating a severe disease stage.Early treatment focuses on strengthening the vital qi and spleen,reducing turbidity and recovering clarity.In the middle stage,the key is to resolve phlegm,eliminate stasis,and promote clarity while removing turbidity.In the late stage,detoxification,turbidity elimination,and restoring clarity are emphasized.By adhering to the characteristics of the pathological mechanism and using traditional Chinese medicine intervention,it is possible to suppress oxidative stress,prevent pathological remodeling of the extracellular matrix,and improve myocardial fibrosis.
