Indobufen or Aspirin on Top of Clopidogrel After Coronary Drug-Eluting Stent Implantation (OPTION): A Randomized, Open-Label, End Point-Blinded, Noninferiority Trial.

BACKGROUND: Dual antiplatelet therapy (DAPT) with aspirin as a background therapy has become the standard care after percutaneous coronary intervention. However, some adverse noncardiac effects limited the use of aspirin in clinical practice. Thus, evaluation of pharmacological alternatives to aspirin is attractive. Previous data indicated that indobufen could lessen the unwanted side effects of aspirin while retaining the antithrombotic efficacy, but its combination with a P2Y12 inhibitor still lacks randomized clinical trial evidence. METHODS: In this randomized, open-label, noninferiority trial, patients with negative cardiac troponin undergoing coronary drug-eluting stent implantation were randomly assigned in a 1:1 ratio to receive either indobufen-based DAPT (indobufen 100 mg twice a day plus clopidogrel 75 mg/d for 12 months) or conventional DAPT (aspirin 100 mg/d plus clopidogrel 75 mg/d for 12 months). The primary end point was a 1-year composite of cardiovascular death, nonfatal myocardial infarction, ischemic stroke, definite or probable stent thrombosis, or Bleeding Academic Research Consortium criteria type 2, 3, or 5 bleeding. The end points were adjudicated by an independent Clinical Event Committee. RESULTS: Between January 11, 2018, and October 12, 2020, 4551 patients were randomized in 103 cardiovascular centers: 2258 patients to the indobufen-based DAPT group and 2293 to the conventional DAPT group. The primary end point occurred in 101 patients (4.47%) in the indobufen-based DAPT group and 140 patients (6.11%) in the conventional DAPT group (absolute difference, -1.63%; Pnoninferiority<0.001; hazard ratio, 0.73 [95% CI, 0.56-0.94]; P=0.015). Cardiovascular death, nonfatal myocardial infarction, ischemic stroke, and stent thrombosis were observed in 0.13%, 0.40%, 0.80%, and 0.22% of patients in the indobufen-based DAPT group and 0.17%, 0.44%, 0.83%, and 0.17% of patients in the conventional DAPT group (all P>0.05). The occurrence of Bleeding Academic Research Consortium criteria type 2, 3, or 5 bleeding events was lower in the indobufen-based DAPT group compared with the conventional DAPT group (2.97% versus 4.71%; hazard ratio, 0.63 [95% CI, 0.46-0.85]; P=0.002), with the main decrease in type 2 bleeding (1.68% versus 3.49%; hazard ratio, 0.48 [95% CI, 0.33-0.70]; P<0.001). CONCLUSIONS: In Chinese patients with negative cardiac troponin undergoing drug-eluting stent implantation, indobufen plus clopidogrel DAPT compared with aspirin plus clopidogrel DAPT significantly reduced the risk of 1-year net clinical outcomes, which was driven mainly by a reduction in bleeding events without an increase in ischemic events.

Medical students' perceptions of an artificial intelligence (AI) assisted diagnosing program.

As artificial intelligence (AI) assisted diagnosing systems become accessible and user-friendly, evaluating how first-year medical students perceive such systems holds substantial importance in medical education. This study aimed to assess medical students' perceptions of an AI-assisted diagnostic tool known as 'Glass AI.' Data was collected from first year medical students enrolled in a 1.5-week Cell Physiology pre-clerkship unit. Students voluntarily participated in an activity that involved implementation of Glass AI to solve a clinical case. A questionnaire was designed using 3 domains: 1) immediate experience with Glass AI, 2) potential for Glass AI utilization in medical education, and 3) student deliberations of AI-assisted diagnostic systems for future healthcare environments. 73/202 (36.10%) of students completed the survey. 96% of the participants noted that Glass AI increased confidence in the diagnosis, 43% thought Glass AI lacked sufficient explanation, and 68% expressed risk concerns for the physician workforce. Students expressed future positive outlooks involving AI-assisted diagnosing systems in healthcare, provided strict regulations, are set to protect patient privacy and safety, address legal liability, remove system biases, and improve quality of patient care. In conclusion, first year medical students are aware that AI will play a role in their careers as students and future physicians.

Global Research Hotspots in Venous Thromboembolism Anticoagulation: A Knowledge-Map Analysis from 2012 to 2021.

Background: Venous thromboembolism (VTE) is a common cardiovascular disease that seriously threatens human lives. Anticoagulant therapy is considered to be the cornerstone of VTE treatment. An increasing number of studies has been updated in the VTE anticoagulation field. However, no bibliometric analyses have assessed these publications comprehensively. Therefore, our study aimed to analyze the global status, hotspots, and trends of anticoagulant therapy for VTE. Methods: The relevant literature on VTE anticoagulation published between 2012 and 2021 was retrieved and collected from the Web of Science Core Collection database. VOSviewer, Cooccurrence Matrix Builder, gCLUTO, and some online visualization tools were adopted for bibliometric analysis. Results: A total of 15,152 related articles were retrieved. In recent years, the research output of VTE anticoagulation gradually increased. The United States was the most productive country. International cooperation is concentrated in North America and Europe; the most influential documents, journals, authors, and organizations were also from these two continents. Research hotspots mainly focus on clinical guidelines, VTE in special populations, non-vitamin K oral anticoagulants (NOACs), and parenteral anticoagulation. The research frontiers and trends include the assessment of NOACs and the antithrombotic management of VTE complicated with coronavirus disease 2019 (COVID-19). Conclusion: This bibliometric analysis provides a systematic overview of the VTE anticoagulation research, which will facilitate researchers to better understand the situation of VTE anticoagulation. Future studies should be dedicated to NOACs application and VTE-combined COVID-19 patients.

Clinical comprehensive evaluation of direct oral anticoagulants for patients with atrial fibrillation in China.

BACKGROUND: Direct oral anticoagulants (DOACs) are increasingly recommended over warfarin in stroke prevention for patients with non-valvular atrial fibrillation (AF). However, there is an important evidence gap in choosing the most appropriate DOAC for Chinese patients in clinical practice. METHODS: A multi-criteria decision analysis (MCDA) was adopted to build a scoring framework. Attributes and criteria were identified and determined by a scoping literature review, two rounds of Delphi surveys, and a consensus meeting. Weights of each attribute and criterion in the framework were determined using analytic hierarchy process (AHP). Evidence was collected based on the domestic or at least Asian data. Scoring methods for each criterion were developed depended on their characteristics and determined with an expert consensus meeting. Comprehensive scores of each DOAC were calculated based on the utility scores of each criterion and their corresponding weights. RESULTS: A total of 5 attributes, including safety, efficacy, costs/cost-effectiveness, suitability, and accessibility, were determined, and 16 criteria were under the 5 attributes. The safety and efficacy were ranked as the top two important attributes with the weights of 38.8% and 35.9%, respectively, while the suitability received the lowest weight of 7.9%. The comprehensive score for edoxaban was the highest (72.3), followed by dabigatran (49.7), rivaroxaban (37.9), and apixaban (35.8). CONCLUSIONS: This study provided a scoring framework developed for comprehensive evaluation of DOACs in China. The ranking of DOACs could help to support the decision-making in clinical practice. The framework could provide a reference for comprehensive evaluation of other drugs.

Cardiovascular protective effects of GLP-1: a focus on the MAPK signaling pathway.

Cardiovascular and related metabolic diseases are significant global health challenges. Glucagon-like peptide 1 (GLP-1) is a brain-gut peptide secreted by the ileal endocrine system and is now an established drug target in type 2 diabetes (T2DM). GLP-1 targeting agents have been shown not only to treat T2DM, but also to exert cardiovascular protective effects by regulating multiple signaling pathways. The mitogen-activated protein kinase (MAPK) pathway, a common signal transduction pathway for transmitting extracellular signals to downstream effector molecules, is involved in regulating diverse cellular physiological processes, including cell proliferation, differentiation, stress, inflammation, functional synchronization, transformation, and apoptosis. The purpose of this review is to highlight the relationship between GLP-1 and cardiovascular disease (CVD) and discuss how GLP-1 exerts cardiovascular protective effects through the MAPK signaling pathway. This review also discusses the future challenges in fully characterizing and evaluating the CVD protective effects of GLP-1 receptor agonists (GLP-1RA) at the cellular and molecular levels. A better understanding of the MAPK signaling pathway that is dysregulated in CVD may aid in the design and development of promising GLP-1RA.

The effectiveness of governmental nonpharmaceutical interventions against COVID-19 at controlling seasonal influenza transmission: an ecological study.

BACKGROUND: A range of strict nonpharmaceutical interventions (NPIs) were implemented in many countries to combat the coronavirus 2019 (COVID-19) pandemic. These NPIs may also be effective at controlling seasonal influenza virus infections, as influenza viruses have the same transmission path as severe acute respiratory syndrome coronavirus 2. The aim of this study was to evaluate the effects of different NPIs on the control of seasonal influenza. METHODS: Data for 14 NPIs implemented in 33 countries and the corresponding influenza virological surveillance data were collected. The influenza suppression index was calculated as the difference between the influenza positivity rate during its period of decline from 2019 to 2020 and during the influenza epidemic seasons in the previous 9 years. A machine learning model was developed using an extreme gradient boosting tree regressor to fit the NPI and influenza suppression index data. The SHapley Additive exPlanations tool was used to characterize the NPIs that suppressed the transmission of influenza. RESULTS: Of all NPIs tested, gathering limitations had the greatest contribution (37.60%) to suppressing influenza transmission during the 2019-2020 influenza season. The three most effective NPIs were gathering limitations, international travel restrictions, and school closures. For these three NPIs, their intensity threshold required to generate an effect were restrictions on the size of gatherings less than 1000 people, ban of travel to all regions or total border closures, and closing only some categories of schools, respectively. There was a strong positive interaction effect between mask-wearing requirements and gathering limitations, whereas merely implementing a mask-wearing requirement, and not other NPIs, diluted the effectiveness of mask-wearing requirements at suppressing influenza transmission. CONCLUSIONS: Gathering limitations, ban of travel to all regions or total border closures, and closing some levels of schools were found to be the most effective NPIs at suppressing influenza transmission. It is recommended that the mask-wearing requirement be combined with gathering limitations and other NPIs. Our findings could facilitate the precise control of future influenza epidemics and other potential pandemics.

Hip abductor strength-based exercise therapy in treating women with moderate-to-severe knee osteoarthritis: a randomized controlled trial.

OBJECTIVE: To investigate whether hip abductor strength-based exercise therapy could result in further function improvement and more pain relief in women with knee osteoarthritis. DESIGN: Randomized controlled trial. SETTINGS: Rehabilitation department of Affiliated Hospital of Southwest Medical University from years 2016 to 2018. SUBJECTS: In total, 82 women aged 50-70 years, with knee osteoarthritis grade II-IV on the Kellgren-Lawrence scale. INTERVENTION: The experimental group engaged in hip abductor strength-based exercises under the supervision of physical therapists (once a day for six weeks), while the control group engaged in quadriceps femoris strength-based exercises. MAIN MEASURES: Osteoarthritis severity measured by the Western Ontario and McMaster Universities Osteoarthritis Index, pain on a visual analogue scale and three objective functional tests were assessed at the sixth and 12th week. Repeated measures analysis of variance and multivariable analysis were applied. RESULTS: Finally, 72 participants completed the study: 35 in the experimental group and 37 in the control group. The self-reported functional difficulties score in the experimental group was significantly lower than that in the control group both at the sixth week and at the 12th week (P < 0.001). There were significant differences between groups in the stair ascent/descent task and Figure of 8 Walk test, but not in the Five Times Sit-to-Stand Test. The pain in the experimental group decreased compared with that in the control group at the sixth week (P < 0.05), but not at the 12th week (P > 0.05). CONCLUSION: Hip abductor strength-based exercises could result in better performance and higher self-reported function in women with symptomatic knee osteoarthritis.

Is Platelet-rich Plasma Injection Effective for Chronic Achilles Tendinopathy? A Meta-analysis.

BACKGROUND: Chronic Achilles tendinopathy is common in the general population, and platelet-rich plasma (PRP) is seeing increased use to treat this problem. However, studies disagree as to whether PRP confers a beneficial effect for chronic Achilles tendinopathy, and no one to our knowledge has pooled the available randomized trials in a formal meta-analysis to try to reconcile those differences. QUESTIONS/PURPOSES: In the setting of a systematic review and meta-analysis of randomized controlled trials (RCTs), we asked: Does PRP plus eccentric strength training result in (1) greater improvements in Victorian Institute of Sports Assessment-Achilles (VISA-A) scores; (2) differences in tendon thickness; or (3) differences in color Doppler activity compared with placebo (saline) injections plus eccentric strength training in patients with chronic Achilles tendinopathy? METHODS: A search of peer-reviewed articles was conducted to identify all RCTs using PRP injection with eccentric training for chronic Achilles tendinopathy in the electronic databases of PubMed, Web of Science (SCI-E/SSCI/A&HCI), and EMBASE from January 1981 to August 2017. Results were limited to human RCTs and published in all languages. Two reviewers assessed study quality using the Cochrane Collaboration risk-of-bias tool. All the included studies had low risk of bias. The primary endpoint was improvement in the VISA-A score, which ranges from 0 to 100 points, with higher scores representing increased activity and less pain; we considered the minimum clinically important difference on the VISA-A to be 12 points. Secondary outcomes were tendon thickness change (with a thicker tendon representing more severe disease), color Doppler activity (with more activity representing a poorer result), and other functional measures (such as pain and return to sports activity). Four RCTs involving 170 participants were eligible and included 85 participants treated with PRP injection and eccentric training and 85 treated with saline injection and eccentric training. The patients in both PRP and placebo (saline) groups seemed comparable at baseline. We assessed for publication bias using a funnel plot and saw no evidence of publication bias. Based on previous studies, we had 80% power to detect a 12-point difference on the VISA-A score with the available sample size in each group. RESULTS: With the numbers available, there was no difference between the PRP and saline groups regarding the primary outcome (VISA-A score: mean difference [MD], 5.3; 95% confidence interval [CI], -0.7 to 11.3; p = 0.085). Likewise, we found no difference between the PRP and saline groups in terms of our secondary outcomes of tendon thickness change (MD, 0.2 mm; 95% CI, 0.6-1.0 mm; p = 0.663) and color Doppler activity (MD, 0.1; 95% CI, -0.7 to 0.4; p = 0.695). CONCLUSIONS: PRP injection with eccentric training did not improve VISA-A scores, reduce tendon thickness, or reduce color Doppler activity in patients with chronic Achilles tendinopathy compared with saline injection. Larger randomized trials are needed to confirm these results, but until or unless a clear benefit has been demonstrated in favor of the new treatment, we cannot recommend it for general use. LEVEL OF EVIDENCE: Level I, therapeutic study.

Effects of short-wave therapy in patients with knee osteoarthritis: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy and safety of short-wave therapy with sham or no intervention for the management of patients with knee osteoarthritis. METHODS: We searched the following databases from their inception up to 26 October 2016: MEDLINE, CENTRAL, EMBASE, Physiotherapy Evidence Database, CINAHL and OpenGrey. Studies included randomized controlled trials compared with a sham or no intervention in patients with knee osteoarthritis. The results were calculated via standardized mean difference (SMD) and risk ratio for continuous variables outcomes as well as dichotomous variables, respectively. Heterogeneity was explored by the I2 test and inverse-variance random effects analysis was applied to all studies. RESULTS: Eight trials (542 patients) met the inclusion criteria. The effect of short-wave therapy on pain was found positive (SMD, -0.53; 95% CI, -0.84 to -0.21). The pain subgroup showed that patients received pulse modality achieved clinical improvement (SMD, -0.83; 95% CI, -1.14 to -0.52) and the pain scale in female patients decreased (SMD, -0.53; 95% CI, -0.98 to -0.08). In terms of extensor strength, short-wave therapy was superior to the control group ( p < 0.05, I2 = 0%). There was no significant difference in the physical function (SMD, -0.16; 95% CI, -0.36 to 0.05). For adverse effects, there was no significant difference between the treatment and control group. CONCLUSION: Short-wave therapy is beneficial for relieving pain caused by knee osteoarthritis (the pulse modality seems superior to the continuous modality), and knee extensor muscle combining with isokinetic strength. Function is not improved.

Effects of whole-body vibration on neuromuscular performance in individuals with spinal cord injury: a systematic review.

OBJECTIVE: To examine the effects of whole-body vibration on neuromuscular performance in people with spinal cord injury and evaluate the safe and effective vibration protocols. METHODS: PubMed, EMBASE, CINAHL and PEDro were mainly searched for English literatures. Other data sources were ClinicalTrials.gov , Current Controlled Trials and reference lists of all relevant articles. The PEDro scale was used to evaluate the methodological quality, and the Oxford Centre for Evidence-based Medicine level of evidence was used to assess the level of evidence. Basic information and whole-body vibration protocols were extracted by two independent researchers. Any disagreements were resolved by the third researcher. RESULTS: Of the eight included studies involving 94 individuals with spinal cord injury and 24 able-bodied participants, six of them reported beneficial effects of whole-body vibration on muscle activation and the other two on muscle spasticity. Based on the reviewed studies, an intermittent mode of whole-body vibration (frequency: 10-50 Hz; amplitude: 0.6-4 mm) is less likely to cause adverse events when applying to spinal cord injury subjects standing on platform (knees flexed at 10°-40°). CONCLUSIONS: The strength of evidence is insufficient in supporting the benefits of whole-body vibration on neuromuscular performance in individuals with spinal cord injury. The intermittent vibration (frequency: 10-50 Hz; amplitude: 0.6-4 mm; knee flexion: 10°-40°) may be the possible effective range and have good compliance.

Factors that influence full-time MPH Students' willingness in China: would You apply again for an MPH graduate degree if you had another opportunity?

BACKGROUND: Current and emerging challenges to public health in the 21st century are vastly different from those faced in previous centuries. And the shortage of health personnel and their low level of educational qualifications hindered the development of Chinese public health services. In order to fulfill this requirement, the Ministry of Education initiated a full-time, Master of Public Health (MPH) graduate programme in 2009. This study aimed to evaluate the level of graduate students' satisfaction with full-time Master of Public Health (MPH) education in China, and whether they would apply again for an MPH graduate degree if they had another opportunity to do so, as well as to identify the factors influencing their decision-making process. METHODS: An anonymous, web-based survey questionnaire containing 61 items was distributed to 702 MPH students in 35 universities or colleges. The questions covered the categories of student admission, training goals, lecture courses, practical training, research activities and mentorship. Levels of satisfaction were compared between MPH students who would choose MPH again as their graduate degree if they had another opportunity to do so and those who would not. Key influencing factors of training satisfaction were identified using logistic regression models. RESULTS: A total of 65.10% of the participants would apply again for MPH education if they had another opportunity to do so. The factors influencing students' willingness included their university type, the time since admission and their initial willingness. In addition, the four common factors (admissions & lecture courses, research activities & mentorship, practical training and training goals) emerging from factor analysis were all significantly positively correlated with student willingness (p < 0.001). CONCLUSIONS: Most MPH students surveyed were highly satisfied with their MPH education and, although they advocated for improvements and reforms in some aspects, they would still choose MPH as their graduate degree again if they had another opportunity to do so.

Effects of therapeutic ultrasound on pain, physical functions and safety outcomes in patients with knee osteoarthritis: a systematic review and meta-analysis.

OBJECTIVE: To explore the effects of therapeutic ultrasound with sham or no intervention on pain, physical function and safety outcomes in patients with knee osteoarthritis. DATA SOURCES: This systematic review was searched on CENTRAL, EMBASE, MEDLINE, CINAHL, Physiotherapy Evidence Database, Open Gray on 4 September 2015. Trials included randomized controlled trials that compared therapeutic ultrasound with a sham or no intervention in patients with osteoarthritis of the knee. REVIEW METHODS: Eligible trials and extracted data were identified by two independent investigators. Standardized mean differences (SMDs) and 95% confidence interval (CI) were calculated for pain and physical function outcomes. Heterogeneity was assessed by the I2 test and inverse-variance random-effects analysis was applied to all trials. RESULTS: Ten randomized controlled trials (645 patients) met the inclusion criteria. Therapeutic ultrasound showed a positive effect on pain (SMD = -0.93, 95%, CI = -1.22 to -0.64, p < 0.01, p for heterogeneity = 0.12, I2 = 42%). For physical function, therapeutic ultrasound was advantageous for reducingWestern Ontario and McMaster Universities physical function score (SMD = -0.37, 95% CI = -0.73 to -0.01, p = 0.04, p for heterogeneity = 0.94, I2 = 0%). In terms of safety, no occurrence of adverse events caused by therapeutic ultrasound was reported in any trial. CONCLUSION: The authors suggested that therapeutic ultrasound is beneficial for reducing knee pain and improving physical functions in patients with knee osteoarthritis and could be a safe treatment.

[A randomized, placebo controlled study on Fangfeng Tongsheng granule in treatment of sub-acute eczema].

The clinical study was conducted to further evaluation the effectiveness and safety of Fangfeng Tongsheng granule in the treatment of sub-acute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome). In the block randomized, multi-centered study, totally 108 patients were enrolled and assigned to two groups: 72 patients in the test group and 36 patients in the placebo control group. Those in the test group took Fangfeng Tongsheng granule with the dose of 3 g, twice a day, while those in the control group were give simulated agent granules with the same dose. The therapeutic course lasted for 14 days. Their efficacies in TCM syndrome, dermal symptoms and adverse events were observed. According to the test results, except for the one exit case, all of the remaining 108 cases, including 71 in the test group, and 36 in the control group, completed the clinical trial. As for the efficacy of TCM syndrome, after the medication for 2 weeks, the cure rate was 33.81% (24/71) in the test group and 0% (0/36) in the control group (P < 0.01), with a statistical difference between the two groups. Regarding the TCM score, after the medication for 2 weeks, the test group decreased by (12.82 +/- 7.96), while the control group decreased by (3.67 +/- 4.12), indicating a statistical difference between the two groups. As for the efficacy of dermal symptoms, after the medication for 2 weeks, the cure rate was 25.35% (18/71) in the test group and 0% (0/36) in the control group, with a statistical difference between the two groups. Regarding the dermal symptom score, after the medication for 2 weeks., the test group decreased by (10.04 +/- 7.17), while the control group decreased by (2.33 +/- 3.57), indicating a statistical difference between the two groups. There was no significant adverse event caused by Fangfeng Tongsheng granule. In conclusion, Fangfeng Tongsheng granule was effective and safe in treating subcute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome).

Optimization strategy of community planning for environmental health and public health in smart city under multi-objectives.

As population density increases, environmental hygiene and public health become increasingly severe. As the space where residents stay for the longest time and have the most profound impact on their physical and mental health, the quality of the environment in urban communities largely determines the degree to which residents engage in physical activity, bear the risk of pollution exposure, and obtain healthy food. Therefore, in order to ensure the physical and mental health of residents, this study proposes community planning guided by environmental hygiene and public health, and establishes an environmental health assessment system for this purpose. This system evaluates the community environment from four aspects: land use, service facilities, site convenience, and environmental quality. Established the diversity, density, road network connectivity and facilities accessibility nine criteria, as well as the land function of mix, plot ratio, food environment, network ring α and connected ß index, pavement risk level, green configuration and neighborhood material environment disorder degree of 27 indicators of community built environmental evaluation index system. The data is collected through field survey, questionnaire distribution, resident interview and data mapping, and the established evaluation index system is used to evaluate the construction environment of the community. The experimental research data included population data, CAD plan, land use data, street data, POI point data, building data and bus station data, etc. 273 questionnaires were distributed, 264 were recovered, 8 invalid questionnaires were removed, and 256 valid questionnaires were obtained. These experiments confirm that land use, service facilities, site convenience, and environmental quality have a significant impact on the built environment of communities, with impact weights of 0.513, 0.227, 0.135, and 0.125, respectively. The above weights are calculated based on the index judgment matrix and the eigenvectors. The scores of land use, service facilities, site convenience, and environmental quality for the study subjects were 3.44, 1.46, 0.94, and 0.51, respectively, among them, the land use score is less than 3.85, the 1 service facility score is less than 1.71, the site convenience score is less than 1.01, and the environmental quality score is less than 0.94; indicating that the community has serious problems such as single land use types, pollution exposure, and difficulty in obtaining healthy food. Therefore, community planning and transformation based on land use, service facilities, venue convenience, and environmental quality can effectively improve the physical and mental health of residents. In the specific community transformation plan, artificial intelligence and data-driven methods can be used to optimize the land use plan, service facility configuration, site convenience transformation and environmental quality improvement, so as to formulate the optimal community transformation plan and improve the comfort and happiness of community residents. In the future, on the basis of the existing research, the selection of community types will be further enriched and the research cases will be expanded. And through the in-depth practical study of the case, the constructed evaluation index system is optimized and improved to make it more scientific. At the same time, as urban renewal and design have entered the era of stock planning, based on the more perfect evaluation index system, more specific and detailed system discussion of the built communities with public health problems, in order to provide more detailed services for the construction of a better and healthy living environment in the future.

Improving intestinal inflammaging to delay aging? A new perspective.

Greying population is becoming an increasingly critical issue for social development. In advanced aging context, organismal multiple tissues and organs experience a progressive deterioration, initially presenting with functional decline, followed by structural disruption and eventually organ failure. The aging of the gut is one of the key links. Decreased gut function leads to reduced nutrient absorption and can perturb systemic metabolic rates. The degeneration of the intestinal structure causes the migration of harmful components such as pathogens and toxins, inducing pathophysiological changes in other organs through the "brain-gut axis" and "liver-gut axis". There is no accepted singular underlying mechanism of aged gut. While the inflamm-aging theory was first proposed in 2000, the mutual promotion of chronic inflammation and aging has attracted much attention. Numerous studies have established that gut microbiome composition, gut immune function, and gut barrier integrity are involved in the formation of inflammaging in the aging gut. Remarkably, inflammaging additionally drives the development of aging-like phenotypes, such as microbiota dysbiosis and impaired intestinal barrier, via a broad array of inflammatory mediators. Here we demonstrate the mechanisms of inflammaging in the gut and explore whether aging-like phenotypes in the gut can be negated by improving gut inflammaging.

Crataegus pinnatifida: A botanical, ethnopharmacological, phytochemical, and pharmacological overview.

ETHNOPHARMACOLOGICAL RELEVANCE: Crataegus pinnatifida belongs to the Rosaceae family and extensively distribute in North China, Europe, and North America. Its usage was first described in "Xinxiu Ben Cao." The dried fruits of Crataegus pinnatifida Bunge or Crataegus pinnatifida var. major N. E. Br., also known as "Shanzha," is a famous medicine and food homology herb with a long history of medicinal usage in China. C. pinnatifida has the functions for digestive promotion, cardiovascular protection, and lipid reduction. It was traditionally used to treat indigestion, cardiodynia, thoracalgia, hernia, postpartum blood stagnation, and hemafecia. In recent years, C. pinnatifida has attracted worldwide attention as an important medicinal and economical crop due to its multiple and excellent health-promoting effects on cardiovascular, nervous, digestive, endocrine systems, and morbigenous microorganisms of the human body due to its medicinal and nutritional values. AIM OF THE REVIEW: The current review aims to provide a comprehensive analysis of the geographical distribution, traditional usage, phytochemical components, pharmacological actions, clinical settings, and toxicities of C. pinnatifida. Moreover, the connection between the claimed biological activities and the traditional usage, along with the future perspectives for ongoing research on this plant, were also critically summarized. MATERIALS AND METHODS: We collected the published literature on C. pinnatifida using a variety of scientific databases, including Web of Science, ScienceDirect, PubMed, Wiley, Springer, Taylor & Francis, ACS Publications, Google Scholar, Baidu Scholar, CNKI, The Plant List Database, and other literature sources (Ph.D. and MSc dissertations) from 2012 to 2022. RESULTS: In the last decade, over 250 phytochemical compounds containing lignans, phenylpropanoids, flavonoids, triterpenoids, and their glycosides, as well as other compounds, have been isolated and characterized from different parts, including the fruit, leaves, and seeds of C. pinnatifida. Among these compounds, flavonoids and triterpenoids were major bioactive components of C. pinnatifida. They exhibited a broad spectrum of pharmacological actions with low toxicity in vitro and in vivo, such as cardiovascular protection, neuroprotection, anti-inflammatory, antioxidant, antibacterial, antiviral, anti-diabetes, anti-cancer, anti-mutagenic, anti-osteoporosis, anti-aging, anti-obesity, and hepatoprotection and other actions. CONCLUSION: A long history of traditional uses and abundant pharmacochemical and pharmacological investigations have demonstrated that C. pinnatifida is an important medicine and food homology herb, which displays outstanding therapeutic potential, especially in the digestive system and cardiovascular disease. Nevertheless, the current studies on the active ingredients or crude extracts of C. pinnatifida and the possible mechanism of action are unclear. More evidence-based scientific studies are required to verify the traditional uses of C. pinnatifida. Furthermore, more efforts must be paid to selecting index components for quality control research and toxicity and safety studies of C. pinnatifida.

Efficacy and Safety of Panax notoginseng Saponins in the Treatment of Adults With Ischemic Stroke in China: A Randomized Clinical Trial.

Importance: Preclinical and clinical studies have suggested the neuroprotective effect of Panax notoginseng saponins (Xuesaitong soft capsules). However, robust evidence in patients with ischemic stroke is lacking. Objective: To assess the efficacy and safety of Xuesaitong soft capsules in patients with ischemic stroke. Design, Setting, and Participants: This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted at 67 tertiary health centers in China from July 1, 2018, to June 30, 2020. Included patients were aged 18 to 75 years with a diagnosis of ischemic stroke and a National Institutes of Health Stroke Scale score between 4 and 15. Interventions: Eligible patients were randomly assigned within 14 days after symptom onset to receive either treatment with Xuesaitong soft capsules (120 mg orally twice daily) or placebo (120 mg orally twice daily) for 3 months. Main Outcomes and Measures: The primary outcome was functional independence at 3 months, defined as a modified Rankin Scale score of 0 to 2. Results: Among 3072 eligible patients with ischemic stroke who were randomized, 2966 (96.5%) were included in the modified intention-to-treat cohort (median [IQR] age, 62 [55-68] years; 1982 male [66.8%]). The number of patients who achieved functional independence at 3 months was 1328 (89.3%) in the Xuesaitong group and 1218 (82.4%) in the control group (odds ratio, 1.95; 95% CI, 1.56-2.44; P < .001). In the safety cohort, serious adverse events occurred in 15 of 1488 patients (1.0%) in the Xuesaitong group and 16 of 1482 (1.1%) in the control group (P = .85). Conclusions and Relevance: In this randomized clinical trial, Xuesaitong soft capsules significantly increased the likelihood of functional independence at 3 months in patients with ischemic stroke, indicating that this may be a safe and effective alternative therapy to improve prognosis in this population.

Effects of shock wave therapy in patients with carpal tunnel syndrome: a systematic review and meta-analysis.

PURPOSE: To determine whether shock wave therapy could improve symptoms and hand function in patients with carpal tunnel syndrome. MATERIALS AND METHODS: Medline, Embase, Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials, OpenGrey, CNKI, VIP, Wang Fang databases, and China Biological Medicine were searched, from inception to December 2019. RESULTS: Ten trials involving 433 patients (501 wrists) were included in this systematic review. The shock wave therapy was observed to have a significant effect on pain relief (MD: -0.60, 95% CI: -1.16 to -0.05, p = 0.03), syndrome alleviation (MD: -2.26, 95% CI: -3.24 to -1.27, p < 0.00001) and functional recovery (MD: -1.25 95% CI: -2.08 to -0.43, p = 0.003) among the carpal tunnel syndrome patients. As revealed by the subgroup analysis, radial shock wave therapy made a significant difference in pain relief, syndrome alleviation, and functional recovery (p < 0.05). Focused shock wave had no significant effect on pain relief, syndrome alleviation, and functional recovery (p > 0.05). CONCLUSION: Shock wave therapy could be conductive to improve syndrome and hand function for carpal tunnel syndrome patients.Implications for rehabilitationShock wave therapy is beneficial for alleviating syndrome and improving hand function of carpal tunnel syndrome patients.Radial shock wave therapy seems superior to focused shock wave therapy on syndrome alleviation and functional recovery of hand in carpal tunnel syndrome patients.

Risk of device-related thrombosis following short-term oral anticoagulation with low-dose dabigatran versus warfarin after Watchman left atrial appendage occlusion.

BACKGROUND: Percutaneous left atrial appendage occlusion (LAAO) provides an alternative for poor candidates for long-term oral anticoagulation (OAC). To prevent device-related thrombosis (DRT), OAC should be continued for the first 45 days to allow complete endothelialization post-LAAO implantation. Whereas, evidence is limited on the feasibility and safety of direct oral anticoagulants (DOACs) used after LAAO. METHODS: This was a retrospective observational single-center study of AF patients undergoing LAAO with a Watchman device and receiving either low-dose dabigatran (110mg twice daily) or warfarin in the peri- and post-procedural period for 45 days. Transesophageal echocardiography was scheduled to perform at 6 weeks, 6 months, and 12 months after the procedure to assess the stability of the device and to detect DRT. Incidence of thromboembolic and bleeding events were also evaluated during the follow-up period. RESULTS: There were a total of 84 patients who successfully underwent Watchman implantation, with 38 patients (45.2%) receiving low-dose dabigatran and 46 patients (54.8%) using warfarin post-LAAO. Peri-procedural complications occurred in 10 patients, with 3 patients in the dabigatran group and 7 patients in the warfarin group (7.9% vs. 15.2%, p = 0.30). During the 12-month follow-up, 1 patient experienced major bleeding and 16 patients suffered minor bleeding in the warfarin group, while 5 patients treated with dabigatran had minor bleeding (34.8% vs. 13.2%, p = 0.02). Besides, 6 DRT (15.8%) were detected in dabigatran groups, and the incidence was higher than in the warfarin group (15.8% vs. 2.2%, p = 0.03). No DRT-related ischemic events were found. CONCLUSIONS: This study suggested that short-term low-dose dabigatran (110 mg twice daily) could significantly decrease the risk of bleeding compared with warfarin at the expense of increased risk of DRT post-LAAO. Therefore, low-dose dabigatran should be used with caution for post-implant anticoagulation of LAAO. Further studies are urgently needed on the feasibility and safety of DOACs post-LAAO.
