Background and Objectives: There is no dedicated occlusive device for closing coronary artery fistulas (CAFs), and specific efficacy and safety data of various off-label occlusive devices for CAFs closure are scarce. Methods: Patients undergoing transcatheter closure of CAFs from January 2011 to December 2022 were included in the single-center retrospective study. The study population was divided into 2 groups: coils group (n=35) and patent ductus arteriosus (PDA) occluders group (n=66). Results: No significant intergroup differences were observed in demographic characteristics except age. The presence of multiple CAF origins (54.3% vs. 4.5%, p<0.001) and multiple draining sites (51.4% vs. 3.0%, p<0.001) were more common in the coils group. In contrast, the presence of aneurysm (72.7% vs. 14.3%, p<0.001), and large fistula (75.8% vs. 37.1%, p<0.001) were more prevalent in the PDA occluders group. The acute procedural success rate of the PDA occluders group was higher compared to that of the coils group (87.9% vs.62.9%, adjusted odds ratio [OR], 7.20; 95% confidence interval, 1.59–32.64; p=0.01).In addition, no significant intergroup differences were noted in both the recanalization rate (7.8% vs. 20%, p=0.107) and the reintervention rate (3.1% vs. 8.6%, p=0.342). Conclusions Transcatheter closure of CAFs using PDA occluders was associated with significantly higher acute procedural success rates compared to coil embolization with comparable late outcomes.

Objective: Randomized controlled trials (RCTs) of Chinese patent medicines and classic traditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023. A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments. This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence. Methods: RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evidence Database for Chinese Patent Medicine (AICED-CPM), with supplementary searches conducted in China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, PubMed, Embase, and Web of Science. The study characteristics and methodological quality of these RCTs were systematically analyzed and evaluated. Results: A total of 1 443 RCTs of Chinese patent medicines were included, comprising 1 399 Chinese articles and 44 English articles. Additionally, 334 RCTs of classic traditional Chinese medicine prescriptions were found, with 331 published in Chinese and 3 in English. 196 567 participants were included, covering 585 types of Chinese patent medicines (487 oral, 61 injectable, and 37 topical) and 179 classic traditional Chinese medicine prescriptions. The involved studies encompassed 22 types of diseases, with research primarily focusing on diseases of the circulatory system, the respiratory system, and the genitourinary system. The sample sizes ranged from 18 to 3 777 participants, and most studies were conducted at a single center. Methodologically, the implementation of allocation concealment and blinding remained insufficiently emphasized. Conclusion Overall, compared with 2022, both the number of RCT publications and their methodological quality have improved in 2023, with heightened attention to research on diseases of the genitourinary system. However, quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence.

Objective To investigate the effect of percutaneous balloon mitral valvuloplasty under echocardiographic guidance for patients with moderate to severe mitral stenosis during pregnancy. Methods A retrospective observational study was conducted to include pregnant women who were diagnosed with moderate to severe mitral stenosis and underwent percutaneous balloon mitral valvuloplasty under echocardiographic guidance in Fuwai Hospital from August 2018 to June 2022, and their baseline characteristics, surgical outcomes, echocardiographic results, and follow-up results were analyzed. Results A total of 3 pregnant women aged 30-35 years, with gestational age of 19-26 weeks, and New York Heart Association (NYHA) function class Ⅲ were included. All the procedures were successfully performed. The mitral valve orifice area increased from 0.9 cm2 preoperatively to 2.1 cm2 postoperatively. The mean transvalvular pressure gradient decreased from 15.0 mm Hg preoperatively to 6.7 mm Hg postoperatively. No perioperative adverse events occurred. The follow-up time ranged from 3 to 48 months. All patients delivered uneventfully and returned to normal life, with maternal-fetal safety. Conclusion Percutaneous balloon mitral valvuloplasty under echocardiographic guidance is a feasible and effective procedure for the treatment of patients with moderate to severe mitral stenosis in pregnancy, with satisfactory maternal-fetal outcomes.

ObjectiveTo explore the molecular mechanism of modified Shengjiangsan in alleviating endoplasmic reticulum （ER） stress and reducing urinary protein in the rat model of diabetic nephropathy （DN）. MethodSeventy-five SD rats were randomized into normal， model， low-， medium-， and high-dose （4.37， 8.73， 17.46 g·kg^-1， respectively） modified Shengjiangsan， and irbesartan （0.014 g·kg^-1） groups， with 10 rats in each group. Rats were administrated with corresponding doses of medications or distilled water by gavage， once a day， for 8 consecutive weeks. After the last administration， the levels of glucose （GLU） in the blood， 24-hour urinary protein （24 h-UTP）， and superoxide dismutase （SOD）， malondialdehyde （MDA）， and glutathione peroxidase （GSH-Px） in the renal tissue were measured. Hematoxylin-eosin staining， periodic acid-Schiff staining， and transmission electron microscopy were employed to observe the pathological changes in rat kidneys. Immunohistochemistry was employed to measure the expression levels of nephrin， podocin， glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， and activating transcription factor 4 （ATF4） in the kidneys of rats. Western blot was employed to measure the protein levels of silent information regulator 1 （Sirt1）， phosphorylated （p）-protein kinase RNA-like endoplasmic reticulum kinase （PERK）， and p-eukaryotic translation initiation factor 2 alpha （eIF2α） in rat kidneys. ResultCompared with the normal group， the modeling caused pathological damage to the kidneys， elevated the levels of GLU and 24 h-UTP （P<0.05）， up-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and down-regulated the protein level of Sirt1 （P<0.05） in rat kidneys. Compared with the model group， modified Shengjiangsan and irbesartan lowered the GLU and 24 h-UTP levels （P<0.05）， alleviated the pathological damage in the renal tissue， down-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and up-regulated the protein level of Sirt1 （P<0.05）. ConclusionModified Shengjiangsan up-regulates Sirt1 expression and inhibits phosphorylation of proteins in the PERK/eIF2α pathway to reduce ER stress and oxidative stress in the renal tissue， thus alleviating the pathological damage in the renal tissue and reducing urinary protein in DN rats.

Objective To explore the method and feasibility of establishing patent ductus arteriosus (PDA) model in Bama miniature pig by using autologous jugular vein, and to provide a large animal model for the development of PDA occluder and the study of pulmonary hypertension associated with congenital heart disease. Methods Five male Bama miniature pigs weighing about 45 kg were selected to gain the PDA model of the autogenous jugular vein, which was fixed by glutaraldehyde and anastomosed between the ascending aorta and the main pulmonary artery. The patency of PDA was confirmed by echocardiography and angiocardiography immediately and one week after the operation. Two animals were selected to undergo transcatheter closure of PDA via femoral vein 1 week after the operation, and the rest were euthanized to obtain PDA and lung tissue for pathological examination. Results The PDA model was successfully established in all five animals with a success rate of 100.0%. Immediately and 1 week after the operation, echocardiography and angiography showed that PDA blood flow was unobstructed, and hematoxylin-eosin staining showed that PDA endothelialization was good. One week after the operation, two animals were successfully treated with transcatheter femoral vein occlusion. The pathological examination of lung tissue showed thickening of the intima and muscular layer of pulmonary arterioles, thickening of pulmonary interstitium and infiltration of neutrophils. Conclusion It is safe and feasible to establish a large animal model of PDA by using autogenous jugular vein anastomosis between the ascending aorta and the main pulmonary artery. The model can be used for the development of PDA interventional occlusive devices and the pathophysiological study of congenital heart disease-related pulmonary hypertension.

Objective Traditional Chinese medicine tongue diagnosis plays an important role in the clinical diagnosis and treatment of diseases,but the current research results are not applicable to the evaluation of clinical efficacy.This study conducted a hierarchical quantitative study on tongue color based on hyperspectral data of tongue images,making it suitable for clinical efficacy evaluation.Methods Establish inclusion and exclusion criteria,obtain tongue images of different spectral wavelengths within the visible light range of 400-1000 nm,and use traditional Chinese medicine clinical experts to distinguish between red tongue and yellow coating in four different color levels(mild,moderate,severe,and severe).Finally,establish a quantitative prediction model for the grade of red tongue and yellow coating based on machine learning models.Results There were significant differences in hyperspectral curve characteristics between red tongue and yellow coating with different color levels,which could be used as the basis for grade quantification.With the help of principal component analysis+random forest model,85.79%and 88.34%of the red tongue and yellow coating with different color levels could be predicted.Conclusion The use of hyperspectral image data features and machine learning models for predicting different color levels of tongue color has achieved good accuracy.

Objective:To analyze the influence of midwifeled accompanyon the psychological status and delivery outcomes of gestational diabetes patients, and to provide reference for the implementation of clinical intervention programs for gestational diabetes patients.Methods:A semi-randomized controlled trial was adopted.Convenience sampling method was used to select 120 gestational diabetes patients admitted to Langfang People′s Hospital from March 2021 to September 2023, and they were divided into control group and experimental group according to the admission order. Both groups were given intraspinal delivery analgesia, while the control group was combined with routine midwifery management, and the experimental group was combined with a midwife led accompany. Intervention lasted until 2 h postpartum in both groups, and follow-up for 1 month. The delivery indicators, psychological status, delivery outcome and satisfaction of the two groups were compared.Results:Finally, 120 gestational diabetes patients were included, 60 patients in the control group, aged (28.73 ± 2.79) years, and 60 patients in the experimental group, aged (27.98 ± 1.09) years. The first and second stages of labor in the experimental group were (416.35 ± 29.87) and (60.95 ± 7.44) min, respectively, which were shorter than (501.33 ± 37.59) and (80.28 ± 8.95) min in the control group, and the differences were statistically significant ( t = 13.71, 12.87, both P<0.05). The blood glucose during delivery and 2 h postpartum hemorrhage was (6.81 ± 0.10) mmol/L and (236.18 ± 37.58) ml, respectively, lower than (7.48 ± 0.45) mmol/L and (325.70 ± 59.88) ml in the control group, the differences were statistically significant ( t = 11.26, 9.81, both P<0.05). After 1 month of follow-up, the scores of Self-rating Anxiety Scale and Self-rating Depression Scale of the experimental group were (30.86 ± 2.55) and (21.45 ± 2.67) points, which were lower than (42.19 ± 3.86) and (42.97 ± 3.15) points in the control group, and the scores of Psychological Resilience Scale were (71.22 ± 6.54) points, which was higher than that of the control group (55.38 ± 6.06) points, the differences were statistically significant ( t = 18.97, 40.37, 13.76, all P<0.05). After intervention, the incidence rates of lateral resection and postpartum hemorrhage in the experimental group were 28.3%(17/60) and 5.0%(3/60), respectively, lower than 48.3%(29/60) and 18.3%(11/60) in the control group, and the total satisfaction rate of the experimental group was 93.3%(56/60), higher than 80.0% (48/60) of the control group. The differences were statistically significant ( χ2 = 5.08, 5.18, 4.62, all P<0.05). Conclusions:The midwife led accompany could shorten the labor process of gestational diabetes patients, reduce their blood glucose during delivery and the amount of blood 2 h postpartum, and improve their psychological status and delivery outcomes, which was conducive to improving patient satisfaction.
