Objective To assess early clinical safety and efficacy of transfemoral transcatheter aortic valve replacement (TF-TAVR) for pure aortic regurgitation (PAR). Methods The clinical data of PAR patients who underwent TAVR in Wuhan Asia Heart Hospital and Wuhan Asia General Hospital from January 2018 to October 2022 were retrospectively analyzed. Patients were divided into a TF-TAVR group and a transapical transcatheter aortic valve replacement (TA-TAVR) group. The clinical data of the patients were analyzed. Results A total of 54 patients were enrolled, including 34 males and 20 females with an average age of 74.43±6.87 years. The preoperative N-terminal pro-B-type natriuretic peptide level was lower [808.50 (143.50, 2 937.00) pg/mL vs. 2 245.00 (486.30, 7 177.50) pg/mL, P=0.015], and the left ventricular end-diastolic diameter (56.00±6.92 mm vs. 63.07±10.23 mm, P=0.005) and sinus junction diameter (32.47±4.41 mm vs. 37.65±8.08 mm, P=0.007) were smaller in the TF-TAVR group. There was no death in the two groups during the hospitalization. Only 1 new death within postoperative 1 month in the TF-TAVR group (cerebral hemorrhage). A total of 2 new deaths in the TF-TAVR group (1 patient of sudden cardiac death and 1 of multiple organ failure), and there was no death in the TA-TAVR group within postoperative 3 months. There was 1 new death in the TA-TAVR group (details unknown), and there was no death in the TF-TAVR group within postoperative 6 months. There was no statistical difference between the two groups in the all-cause mortality and the cumulative survival rate during the follow-up period (P>0.05). The incidence of high atrioventricular block was 36.0% in the TF-TAVR group and 10.3% in the TA-TAVR group (P=0.024). There were no significant differences between the two groups in the perivalvular leakage (≥moderate), valve in valve, a second valve implantation, valve migration, cerebrovascular events, major vascular complications, complete left bundle branch block, new permanent pacemaker implantation or transferring to surgery (P>0.05). However, the incidence rates of complete left bundle branch block and new permanent pacemaker implantation were higher in the TF-TAVR group, accounting for 56.0% and 40.0%, respectively. Conclusion TF-TAVR is a safe and feasible treatment for PAR patients, which is comparable to TA-TAVR in the early postoperative safety and efficacy.

ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.

Objective:To investigate the status quo and influencing factors of social isolation of parents of children with autism spectrum disorder in order to provide theoretical basis for clinical intervention measures.Methods:A total of 340 parents of children with autism spectrum disorder who visited the Children′s Developmental Behavior Center of Third Affiliated Hospital of Sun Yat sen University were selected by the convenience sampling method as research objects during July to November 2023. A cross-sectional survey was investigated by a general information questionnaire, General Alienation Scale, Social Avoidance and Distress Scale, Affiliate Stigma Scale, Family APGAR Index, Chinese Simplified Version of Social Support Scale, and Social Responsiveness Scale.Results:A total of 323 valid questionnaires were collected, including 235 mothers and 88 fathers; 33 individuals aged 25-29 years, 233 individuals aged 30-39 years, and 57 individuals aged 40-60 years. The subjective social isolation score of parents of children with autism spectrum disorder was 33.24 ± 4.92 and the objective social isolation score was 4.00(2.00,7.00). The results of multiple linear regression analysis showed that the subjective social isolation of parents of children with autism spectrum disorder was influenced by factors including self-assessed health status, whether they worked full-time or not, whether they were satisfied with the division of labor in the family caring for their children, affiliate stigma, family care, and social support (all P<0.05); and the objective social isolation of parents was influenced by factors including the severity of autism symptoms, self-assessed health status, affiliate stigma, and family care (all p<0.05). Conclusions:Parents of children with autism spectrum disorder had some degree of social isolation, and the level of subjective social isolation was higher than objective social isolation. Healthcare professionals should pay attention to parents of autistic children who have high levels of symptom severity, poor self-rated health, do not work full-time, and are dissatisfied with the division of labor in the family caring for their child, and take measures to reduce the affiliate stigma, and to increase the level of family care and social support, so as to improve the social isolation of parents of children with autism spectrum disorder.

Objective:To evaluate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of solid intraductal papilloma (sIDP) of breast by comparing with fibronenoma of breast (FA).Methods:The CEUS data of 62 cases of sIDP patients and 94 cases of FA patients that confirmed by pathology in the First Affiliated Hospital of Soochow University from October 2016 to January 2021 were retrospectively analyzed. The patients were divided into sIDP group and FA group according to the pathological results. The enhancement speed, enhancement degree, enhancement uniformity, whether the edge after enhancement was polished, whether the enhancement range was enlarged, whether there was a ring unenhanced area in the inner edge of the lesion and whether the inner edge of the unenhanced area was polished were observed in the two groups. SonoLiver software was used to perform offline analysis of the dynamic process of CEUS in the two groups respectively, the enhancement sequence diagram of the lesions was obtained. The pathological result was taken as the gold standard, univariate analysis was applied, and the parameters with statistical significance between the two groups were included in multivariate Logistic regression analysis to establish a differential diagnosis model. The diagnostic efficiency of sIDP was analyzed by ROC curve and diagnostic model.Results:Compared with the FA group, CEUS in the sIDP group mostly showed fast forward, high enhancement, and the enhancement sequence was mostly centrifugal. After CEUS, the lesion edges in the sIDP group were mostly accompanied by unenhanced areas and the inner edges of the unenhanced areas were not intact, and the differences between the two groups were statistically significant (all P<0.05). Binary Logistic regression showed that age, enhancement degree and enhancement order were independent risk factors for sIDP diagnosis. The ROC curve showed that the area under the ROC curve of age, enhancement degree and enhancement sequence combined for the diagnosis of sIDP was 0.874 (95% CI=0.812-0.922), the accuracy was 76.9%, the sensitivity was 67.7%, the specificity was 83.0%, the positive predictive value was 72.4%, and the negative predictive value was 79.6%. Conclusions:There are significant differences in age, enhancement degree and enhancement sequence between sIDP and FA patients. The three-parameter combination can improve the diagnostic efficiency of sIDP.

ObjectiveTo evaluate the lipid-lowering activity of Quansanqi tablets（QSQ）， an innovative new drug of Panax notoginseng. MethodMice and golden hamsters were used to establish a hyperlipidemia model by injecting egg yolk milk and feeding high-fat diets. The levels of total cholesterol （TC），triglyceride （TG），low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were detected， and liver function indicators ［alanine aminotransferase （ALT）， aspartate amino-transferase （AST）， and alkaline phosphatase （ALP）］ of golden hamsters were detected. Hematoxylin-eosin （HE） staining was used to observe the degree of liver injury. In the experiments， a normal group， a model group， an atorvastatin calcium group， and low-， medium-， and high-dose QSQ groups （0.32， 0.64， 1.28 g·kg^-1 for mice， and 0.16， 0.32， 0.64 g·kg^-1 for golden hamsters） were set up. ResultCompared with the normal group， the acute hyperlipidemia model mice showed increased TC， TG， and LDL-C levels （P<0.01）， and the hyperlipidemia model mice showed increased TC and LDL-C levels （P<0.01）. Additionally， the hyperlipidemia model golden hamsters showed increased serum TC， TG， LDL-C， ALT， AST， and ALP levels （P<0.05， P<0.01）. HE staining indicated the presence of fat accumulation in the liver， accompanied by inflammatory reactions. Compared with the model group， QSQ of various doses could reduce TC， TG， and LDL-C levels in acute hyperlipidemia model mice （P<0.05， P<0.01）， and the high-dose QSQ could reduce TC and LDL-C levels （P<0.01） and increase HDL-C level （P<0.05） in hyperlipidemia model mice， as well as reduce TC， TG， and LDL-C levels in hyperlipidemia model golden hamsters （P<0.05， P<0.01）， especially in the first two weeks. In addition， atorvastatin calcium could further increase ALT， AST， and ALP levels （P<0.05， P<0.01） and aggravate liver function damage， while low-dose QSQ could reduce ALT， AST， and ALP （P<0.05）， and medium- and high-dose QSQ did not cause further liver function damage. ConclusionQSQ have a significant lipid-lowering effect on different hyperlipidemia model animals and can improve liver function and liver injury.

OBJECTIVE: To investigate the spectrum-effect relationship between the total anthraquinone extract of Cassia seeds and fluorouracil (5-Fu)-induced liver injury in mice and identify the effective components in the extract. METHODS: A mouse model of liver injury was established by intraperitoneal injection of 5-Fu, with bifendate as the positive control. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and myeloperoxidase (MPO), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in the liver tissue were detected to investigate the effect of the total anthraquinone extract of Cassia seeds (0.4, 0.8 and 1.6 g/kg) on liver injury induced by 5-Fu. HPLC fingerprints of 10 batches of the total anthraquinone extracts were established to analyze the spectrum- effectiveness of the extract against 5- Fu- induced liver injury in mice and screen the effective components using the grey correlation method. RESULTS: The 5- Fu- treated mice showed significant differences in liver function parameters from the normal control mice (P < 0.05), suggesting successful modelling. Compared with those in the model group, serum ALT and AST activities were decreased, SOD and T- AOC activities significantly increased, and MPO level was significantly lowered in the mice treated with the total anthraquinone extract (all P < 0.05). HPLC fingerprints of the 31 components in the total anthraquinone extract of Cassia seeds showed good correlations with the potency index of 5-Fu-induced liver injury but with varying correlation strengths. The top 15 components with known correlations included aurantio-obtusina (peak 6), rhein (peak 11), emodin (peak 22), chrysophanol (peak 29) and physcion (peak 30). CONCLUSION The effective components in the total anthraquinone extract of Cassia seeds, including aurantio-obtusina, rhein, emodin, chrysophanol, and physcion, are coordinated to produce protective effects against 5-Fu-induced liver injury in mice.

Objective:To explore the mediating roles of family resilience and perceived social support between fear of progression and quality of life in patients with adult pulmonary hypertension, so as to provide guidance for grassroots medical staff to deeply understand and improve the long-term quality of life of adult pulmonary hypertension patients.Methods:Using a convenience sampling method, 219 adult pulmonary hypertension patients who attended Qilu Hospital, Shandong University from July 2021 to February 2022 were selected for a cross-sectional study using the World Health Organization Quality of Life Questionnaire Abbreviated Version (WHOQOL-BREF), Perceived Social Support Scale (PSSS), Shortened Chinese version of the Family Resilience Assessment Scale (FRAS-C) and Chinese version of Fear of Progression Questionnaire-Short Form (FoP-Q-SF) for investigation. A structural equation model was established to evaluate the mediating effect of family resilience and perceived social support on fear of progression and quality of life.Results:The scores of WHOQOL-BREF, PSSS, FRAS-C, and FoP-Q-SF were (45.85 ± 10.22), 66(56, 75), 94(89, 97) and 39(32, 46) points in adult pulmonary hypertension patients. The total scores of WHOQOL-BREF were negatively correlated with FoP-Q-SF ( r = -0.63, P<0.01), and positively correlated with FRAS-C and PSSS ( r=0.54, 0.46, both P<0.01). Family resilience played a partial mediating role between fear of progression and quality of life, accounting for 13.43% of the total effect. Family resilience and perceived social support played a chain mediating role between fear of progression and quality of life, accounting for 2.71% of the total effect. Conclusions:Family resilience-perceived social support play mediating roles between fear of progression and quality of life, healthcare workers can alleviate fear of progression and improve quality of life by promoting the levels of family resilience and perceived social support of adult pulmonary hypertension parents.

Immunoglobulin G4-related sialadenitis (IgG4-RS) is an immune-mediated fibro-inflammatory disease and the pathogenesis is still not fully understood. The aim of this study was to explore the role and mechanism of interleukin-13 (IL-13) in the cellular senescence during the progress of IgG4-RS. We found that the expression of IL-13 and IL-13 receptor α1 (IL-13Rα1) as well as the number of senescent cells were significantly higher in the submandibular glands (SMGs) of IgG4-RS patients. IL-13 directly induced senescence as shown by the elevated activity of senescence-associated β-galactosidase (SA-β-gal), the decreased cell proliferation, and the upregulation of senescence markers (p53 and p16) and senescence-associated secretory phenotype (SASP) factors (IL-1β and IL-6) in SMG-C6 cells. Mechanistically, IL-13 increased the level of phosphorylated signal transducer and activator of transcription 6 (p-STAT6) and mitochondrial-reactive oxygen species (mtROS), while decreased the mitochondrial membrane potential, ATP level, and the expression and activity of superoxide dismutase 2 (SOD2). Notably, the IL-13-induced cellular senescence and mitochondrial dysfunction could be inhibited by pretreatment with either STAT6 inhibitor AS1517499 or mitochondria-targeted ROS scavenger MitoTEMPO. Moreover, IL-13 increased the interaction between p-STAT6 and cAMP-response element binding protein (CREB)-binding protein (CBP) and decreased the transcriptional activity of CREB on SOD2. Taken together, our findings revealed a critical role of IL-13 in the induction of salivary gland epithelial cell senescence through the elevated mitochondrial oxidative stress in a STAT6-CREB-SOD2-dependent pathway in IgG4-RS.

Pain is a complex physiological and psychological activity, involving at least three dimensions, including pain sensation, pain emotion, and pain cognition. Acupuncture can clearly relieve the pain sensation of patients and improve pain emotion and pain cognition induced by pain; acupuncture participates in the multi-dimensional regulation of pain through brain regions of the limbic system such as anterior cingulate cortex (ACC), amygdala (AMY), and hippocampus. By analyzing relevant literature, it has been found that the regulation of acupuncture on pain emotion is mainly related to the activation of pertinent opioid receptors in the ACC, the decrease of the expression of extracellular signal-regulated kinase (ERK), and the promotion of the expression of glutamic acid (Glu) A1, metabotropic glutamate receptor-1 (mGluR1), and γ-aminobutyric acid aminobutyric acid (GABA) B2 protein in the AMY. The regulation of acupuncture on pain cognition is mainly related to the elevation of the expression of protein kinase A (PKA) and phospho-p38 mitogen-activated protein kinase (phospho-p38 MAPK) and the inhibition of cyclic adenosine monophosphate (cAMP)/PKA/cAMP response element-binding protein (CREB) signaling pathway in the ACC.
