Association of overweight/obesity and overweight/obesity-related metabolic dysfunction-associated steatotic liver disease in young adults with coronary artery calcification later in life.

AIM: The association of overweight/obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) in young adulthood with subclinical atherosclerosis [coronary artery calcification (CAC) and abdominal aortic calcification (AAC)] by middle age is unknown. METHOD: In total, 2274 participants aged 28-39 years from the coronary artery risk development in young adults study at year 10 (1995-1996) who were re-examined 15 years later were included. CAC and AAC were measured at year 25 using computed tomography. We examined the utility of three young adult phenotypes (lean group; overweight/obese group; overweight/obese MASLD group) at year 10 in predicting CAC or AAC by middle age. Modified Poisson regression was used to estimate the association between groups and CAC, and AAC. Independent determinates of CAC and AAC were determined with linear regression models. RESULTS: Compared with individuals categorized as lean in young adulthood, the relative risk for CAC by middle age was 1.09 (95% confidence interval: 0.93-1.28) for those with overweight/obesity and 1.32 (95% confidence interval: 1.08-1.61) for those with overweight/obesity-related MASLD. For AAC, no difference was observed between these three groups. Group, systolic blood pressure and group × systolic blood pressure interaction were all the independent determinates for CAC. CONCLUSION: In this study, young adults with overweight/obesity-related MASLD have a higher risk of developing CAC by middle age. These abnormalities are only partially explained by traditional cardiovascular risk factors, and overweight/obesity-related MASLD has an independent impact on CAC. Our study provides evidence for identifying young adults at higher risk of developing subclinical atherosclerosis.

Design, synthesis, and antifungal activity of carboxamide derivatives possessing 1,2,3-triazole as potential succinate dehydrogenase inhibitors.

Succinate dehydrogenase (SDH) is demonstrably one of the most important molecular targets in development of new fungicide. In our continuous efforts to discover novel SDH inhibitors, forty-two carboxamide derivatives containing 1,2,3-triazole ring were designed and synthesized, which were precisely characterized by 1H NMR, ESI-MS, elemental analysis and X-ray single-crystal diffraction. The compounds were screened for antifungal activities against phytopathogenic fungi by mycelia growth inhibition assay in vitro. Compound A3-3 exhibited significant antifungal activity against Sclerotinia sclerotiorum, Botrytis cinerea, Rhizoctonia cerealis and Gaeumannomyces graminsis with EC50 values of 1.08, 8.75, 1.67 and 5.30 µg/mL, respectively, comparable to those of commercial SDHI boscalid. In vivo testing demonstrated that A3-3 was effective for suppressing rape sclerotinia rot, cucumber grey mould and wheat powdery mildew caused by S. sclerotiorum， B. cinerea and Blumeria graminis at a dosage of 200 µg/mL. Inhibition activities against SDH test proved the designed analogues were effective in the enzyme level. The molecular docking simulation revealed that A3-3 interacted with ARG43，TYR58 and TRP173 of the SDH through hydrogen bond and pi-pi interaction, which could explain the probable mechanism of action between the inhibitor and target protein.

Nigrosporanenes C and D, two new cyclohexene derivatives from the enphytic fungus Nigrospora oryzae S4.

Two new cyclohexene derivatives, nigrosporanenes C and D (1 and 2), together with three known compounds (3-5), were isolated from the culture of an endophyte Nigrospora oryzae S4. Their structures were characterized by a combination of detailed spectroscopic analysis and comparison of their NMR data with those reported in the literature. All compounds were tested for anti-phytopathogenic activity, however, none of them showed activity at a concentration of 20 µM.

Preparation of 13X from Waste Quartz and Photocatalytic Reaction of Methyl Orange on TiO2/ZSM-5, 13X and Y-Zeolite.

TiO2 photocatalytic reactions not only remove a variety of organic pollutants via complete mineralization, but also destroy the bacterial cell wall and cell membrane, thus playing an important bactericidal role. However, the post-filtration procedures to separate nanometer-levels of TiO2 and the gradual inactivity of photocatalyst during continuous use are defects that limit its application. In this case, we propose loading TiO2 on zeolite for easy separation and 13X is considered as a promising one. In our study, 13X-zeolite was prepared by a hydrothermal method and the source of Si was extracted from waste quartz sand. For comparison, commercial zeolite with different microporous and mesoporous diameters (ZSM-5 and Y-zeolites) were also used as TiO2 supports. The pore size of the three kinds of zeolites are as follows: Y-zeolite > 13X > ZSM-5. Different TiO2 loading content over ZSM-5, 13X and Y-zeolite were prepared by the sol-gel method. XRD, FTIR, BET, UV-vis, TGA and SEM were used for investigation of material characteristics. In addition, the efficiencies of mineralization and photodegradation were studied in this paper. The effects of the loading ratio of TiO2 over zeolites, initial pH, and concentration on photocatalytic performance are investigated. The relationship between best loading content of TiO2 and pore size of the zeolite was studied. The possible roles of the ZSM-5, 13X-zeolites and Y-zeolites support on the reactions and the possible mechanisms of effects were also explored. The best loading content of TiO2 over ZSM-5, 13X and Y-zeolite was found to be 50 wt%, 12.5 wt% and 7 wt%, respectively. The optimum pH condition is 3 with TiO2 over ZSM-5, 13X-zeolites and Y-zeolites. The results showed that the degradation and mineralization efficiency of 12.5 wt%GT13X (TiO2 over 13X) after 90 min irradiation reached 57.9% and 22.0%, which was better than that of 7 wt%GTYZ (TiO2 over Y-zeolites) while much lower than that of 50 wt%GTZ (TiO2 over ZSM-5). The materials were recycled four times while the degradation was remained at a higher level.

Association of postexercise blood pressure with cardiovascular outcomes and mortality: The CARDIA study.

Postexercise blood pressure (BP) may be a better predictor of cardiovascular risk than office BP, but there is a lack of data supporting this claim. We hypothesized that postexercise BP may be an important prognostic marker. Our aim was to evaluate the association of postexercise BP with major adverse cardiovascular events (MACE) and all-cause mortality. A total of 2581 participants (median age, 46 years; 55.9% women) from the Coronary Artery Risk Development in Young Adults study at year 20 (2005-2006) who underwent a graded exercise treadmill test using a modified Balke graded protocol were included. Postexercise BP was measured at baseline. Cox models were used to estimate the associations of postexercise BP with MACE and all-cause mortality. Participants were followed up until December 31, 2021. In the entire population, postexercise systolic BP showed no significant association with MACE or all-cause mortality, while postexercise diastolic BP was associated with MACE (hazard ratios [HR], 1.27 [95% CI, 1.06-1.52], per 10 mmHg increase) and all-cause mortality (HR, 1.26 [95% CI, 1.05-1.51], per 10 mmHg increase). In the normal BP group, postexercise systolic BP was not significantly associated with MACE or all-cause mortality, and postexercise diastolic BP was strongly associated with MACE (HR, 1.57 [95% CI, 1.18-2.09], per 10 mmHg increase). In this population-based cohort study, postexercise diastolic BP was significantly associated with the risk of MACE and all-cause mortality. Among individuals with normal BP, postexercise diastolic BP could identify those at a higher risk of cardiovascular events.

Association of Hematological Biomarkers of Inflammation with 10-Year Major Adverse Cardiovascular Events and All-Cause Mortality in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease: The ARIC Study.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) increases the risk of cardiovascular disease and existing evidence indicates that MASLD affects the cardiovascular system through systemic inflammation. Our aim was to assess the association of hematological biomarkers of inflammation with the 10-year risk of major adverse cardiovascular events (MACE) and all-cause mortality in MASLD patients. Methods: A total of 1858 MASLD participants from the Atherosclerosis Risk in Communities cohort study at visit 2 (1990-1992) were included. A total of 1338 non-MASLD participants were also included in the comparison. At baseline, hematological biomarkers of inflammation such as leukocytes, neutrophils, lymphocytes, monocytes, and C-reactive protein (CRP) were measured. Participants were followed up for MACE and all-cause mortality for a period of 10 years. Multivariate adjusted Cox models were used to estimate hazard ratios (HR). Results: The 10-year MACE was higher in MASLD participants than in non-MASLD participants (20.8% vs 9.3%). Monocytes (HR 1.114, [95% CI, 1.022-1.216] per 1-SD, P=0.015) and CRP (HR 1.109 [95% CI, 1.032-1.190] per 1-SD, P=0.005) were associated with an increased 10-year risk of MACE, independent of other cardiovascular risk factors. This association was specific to the MASLD population. None of these hematological biomarkers demonstrated a significant association with 10-year all-cause mortality. Conclusion: Increased levels of monocytes and CRP were associated with an increased 10-year risk of MACE in the MASLD population. Hematological biomarkers of inflammation may help identify MASLD populations at higher risk for cardiovascular events.

Risk of Coronary Heart Disease in People with Chronic Obstructive Pulmonary Disease: A Meta-Analysis.

BACKGROUND: Patients with chronic obstructive pulmonary disease complicated with coronary heart disease are a major public health problem, but it has not been widely accepted by the public or health professionals, the purpose of this study is to conduct a meta-analysis of the literature reports on the risk of coronary heart disease in patients with chronic obstructive pulmonary disease. METHODS: Data sources are PubMed and Web of Science searched up to August 2021. Design is meta-analysis. RESULTS: Literature searches yielded 8877 records, meta-analysis showed that the risk of coronary heart disease in chronic obstructive pulmonary disease patients was 1.24 times higher than that in non-chronic obstructive pulmonary disease patients (HR=1.24,95% CL 1.16-1.32). CONCLUSION: The findings suggest that patients with chronic obstructive pulmonary disease are at a higher risk of developing coronary heart disease than non-chronic obstructive pulmonary disease patients.

Comparative effectiveness of herb-partitioned moxibustion plus lifestyle modification treatment for patients with simple obesity: A study protocol for a randomized controlled trial.

INTRODUCTION: Obesity is a global public health issue, which results in many health complications. Moxibustion may serve as an alternative management for simple obesity, where pharmacological therapy is always difficult to be accepted by the majority of obese patients based on its safety. However, the effects of herb-partitioned moxibustion as obesity intervention have not been confirmed. This study is designed as a single-blinded, 3-dummy randomized controlled trial to evaluate the efficacy and safety of herb-partitioned moxibustion plus lifestyle modification treatment in patients with simple obesity. METHODS AND ANALYSIS: This study will be a randomized, controlled trial conducted from April, 2019 to April, 2021 that includes 108 participants who have simple obesity and meet the eligibility criteria. The participants will be randomly divided into 3 treatment groups: heat application group, medicated plaster group, or herb-partitioned moxibustion group. Each treatment will last 4 weeks. The primary outcomes will be the clinical effectiveness. The secondary outcome measures include participants' obesity-related indicators, the IWQOL-Lite scale, and the syndrome score of Traditional Chinese Medicine. Adverse events will be recorded during the intervention period. ETHICS AND DISSEMINATION: Ethical approval of this study was granted by the Ethics Committee of Hubei Provincial Hospital of Traditional Chinese Medicine on 15 November 2018 (Ethics Reference No: HBZY2018-C24-01). Written informed consents will be provided by all participants before they were enrolled in this study. TRIAL REGISTRATION NUMBER: NCT04606680.

Long-term outcomes of single stenting compared with double stenting strategy for unprotected left main coronary artery disease: A protocol for systematic review and meta-analysis.

BACKGROUND: The optimal interventions for unprotected left main coronary artery (ULMCA) disease have long been debated, and long-term clinical studies comparing single stenting to double stenting strategies for ULMCA are currently lacking. METHODS: We plan to perform a systematic review and meta-analysis of clinical trials comparing single stenting with double stents strategy for ULMCA disease. We will search PubMed, EMBASE, Web of science and Cochrane Library using a comprehensive strategy. The related conference proceedings and reference lists of the included studies will also be checked to identify additional studies. Two reviewers will screen retrieved records, extract information and assess the risk of bias independently. STATA software will be used to conduct data synthesis. There is no requirement of ethical approval and informed consent. RESULTS: This study will be submitted to a peer-reviewed journal for publication. CONCLUSION: We hope it will provide a relatively comprehensive reference for clinical practice and future relevant clinical trials. ETHICS AND DISSEMINATION: Ethics approval and patient consent are not required, as this study is a systematic review and meta-analysis. INPLASY REGISTRATION NUMBER: INPLASY2020110030.

[Moxibustion therapy in prevention and treatment of coronavirus disease 2019 (COVID-19): construction and application of non-contact diagnosis and treatment mode].

OBJECTIVE: To establish and promote the non-contact doctor-patient interactive diagnosis and treatment mode based on mobile internet for the treatment of coronavirus disease 2019 (COVID-19) with moxibustion therapy, and to observe the feasibility and effectiveness of the model in the pandemic. METHODS: A total of 43 first-line medical staff and 149 suspected and confirmed cases with COVID-19 [18 cases in medical observation period, 17 cases of mild type (cold dampness and stagnation in the lung), 24 cases of ordinary type (cold-dampness accumulated in the lung) and 90 cases in recovery period (qi deficiency of spleen and lung)] were included. A non-contact doctor-patient interactive diagnosis and treatment platform was established for the treatment of COVID-19 with indirect moxibustion plaster based on mobile internet. By the platform, the patients were instructed to use indirect moxibustion plaster in treatment. For the first-line medical staff and patients in the medical observation period, Zusanli (ST 36), Qihai (CV 6) and Zhongwan (CV 12) were selected. For the mild cases (cold dampness and stagnation in the lung) and the cases of ordinary type (cold-dampness accumulated in the lung), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36) and Guanyuan (CV 4) were selected. In the recovery period (qi deficiency of spleen and lung), Dazhui (GV 14), Feishu (BL 13), Geshu (BL 17), Zusanli (ST 36) and Kongzui (LU 6) were used. The treatment was given once daily for 40 min each time. The intervention lasted for 10 days. After intervention, the infection rate and the improvement in the symptoms and psychological status of COVID-19 were observed in clinical first-line medical staff and COVID-19 patients. RESULTS: In 10 days of intervention with indirect moxibustion plaster, there was "zero" infection among medical staff. Of 43 first-line physicians and nurses, 33 cases had some physical symptoms and psychological discomforts, mainly as low back pain, poor sleep and anxiety. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 78.8% (26/33) and the curative rate was 36.4% (12/33). Regarding the improvements in psychological discomforts, the effective rate was 58.3% (14/24) and the curative rate was 37.5 (9/24). Of 149 patients, 133 cases had the symptoms and psychological discomforts. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 81.2% (108/133) and the curative rate was 34.6% (46/133). Regarding the improvements in psychological discomforts, the effective rate was 76.5% (52/68) and the curative rate was 57.4 % (39/68). CONCLUSION: It is feasible to apply the indirect moxibustion plaster technique based on mobile internet to the treatment COVID-19. This mode not only relieves the symptoms such as cough and fatigue, improves psychological state, but also possibly prevents the first-line medical staff from COVID-19.

[Comparison of therapeutic effects of electroacupuncture and acupoint catgut embedding in redu-cing serum leptin and insulin levels in simple obesity patients].

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) and acupoint catgut embedding in the treatment of simple obesity. METHODS: Simple obesity patients were randomized into EA group (7 men and 36 women, 21－42 years in age) and catgut embedding group (4 men and 37 women, 22－41 years in age). EA (4 Hz/20 Hz, a tolerable strength) was applied to main acupoints Zhongwan (CV12), bilateral Tianshu (ST25), Daheng (SP15), Daimai (GB26), Shuidao (ST28), Zhigou (TE6), Yinlingquan (SP9), Zusanli (ST36), Fenglong (ST40), and Sanyinjiao (SP6), and some auxiliary acupoints for 30 min, once every other day for 30 times. Subcutaneous catgut-embedment was performed in the same acupoints. Nine to 11 acupoints were used every time, once every 10 days for 6 times. Before and after the treatment, fasting serum leptin and insulin (INS) contents were detected by radioimmunoassay, and the correlation between the leptin, INS and the body mass index (BMI) was analyzed, respectively. RESULTS: Following the treatment, the serum leptin and INS concentrations and BMI in both groups were significantly decreased in comparison with those of their own pre-treatment (P<0.01). No significant differences were found between the two groups in the levels of serum leptin and INS after the treatment (P>0.05). There were positive correlations between the decreased BMI and serum leptin/INS contents in both EA and catgut embedding groups (P<0.01). CONCLUSION: Both catgut embedding and EA interventions have a positive effect in reducing body weight of simple obesity patients, which may be related to its effects in down-regulating serum leptin and INS levels and in correcting leptin resistance and insulin resistance.

Mechanisms of Acupuncture Therapy for Simple Obesity: An Evidence-Based Review of Clinical and Animal Studies on Simple Obesity.

Simple obesity is a worldwide epidemic associated with rapidly growing morbidity and mortality which imposes an enormous burden on individual and public health. As a part of Traditional Chinese Medicine (TCM), acupuncture has shown the positive efficacy in the management of simple obesity. In this article, we comprehensively review the clinical and animal studies that demonstrated the potential mechanisms of acupuncture treatment for simple obesity. Clinical studies suggested that acupuncture regulates endocrine system, promotes digestion, attenuates oxidative stress, and modulates relevant molecules of metabolism in patients of simple obesity. Evidence from laboratory indicated that acupuncture regulates lipid metabolism, modulates inflammatory responses, and promotes white adipose tissue browning. Acupuncture also suppresses appetite through regulating appetite regulatory hormones and the downstream signaling pathway. The evidence from clinical and animal studies indicates that acupuncture induces multifaceted regulation through complex mechanisms and moreover a single factor may not be enough to explain the beneficial effects against simple obesity.

Should acupuncture, biofeedback, massage, Qi gong, relaxation therapy, device-guided breathing, yoga and tai chi be used to reduce blood pressure?: Recommendations based on high-quality systematic reviews.

BACKGROUND: This review aims to rate the quality of evidence and the strength of recommendations in high-quality systematic reviews of non-drug therapies. Hypertensive patients who are resistant or non-adherent to antihypertensive drugs may be easier to manage if they choose alternative non-drug therapies for hypertension, based on this review. METHODS: P: Adults (>18 years), except pregnant women, with essential hypertension. I: Cupping, moxibustion, acupuncture, acupoint stimulation, yoga, meditation, tai chi, Qi gong, Chinese massage, massage, spinal manipulation, biofeedback, device-guided breathing therapy, aromatherapy, music therapy, and relaxation approaches. C: 1. No treatment. 2. Sham therapy. 3. Conventional treatment, including antihypertensive drugs and lifestyle modification (e.g., exercise). O: 1. Change in the incidence of cardiovascular death. 2. Change in the incidence of myocardial infarction. 3. Change in the incidence of stroke. 4. Change in blood pressure (BP). 5. Efficacy rate of BP lowering. 6. Adverse effects (review specific). S: Systematic reviews of randomized controlled trials, including meta-analyses and assessments of the methodological quality/risk of bias. INFORMATION SOURCES: Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane library, PubMed, Web of Science, China National Knowledge Infrastructure, and Chinese Scientific Journal Database were searched. The bibliographies of the included articles were also searched for relevant systematic reviews. GRADE criteria were used to rate the quality of evidence in systematic reviews considering 6 factors, including risk of bias. RESULTS: This review ultimately included 13 systematic reviews of 14 non-drug therapies (acupuncture, wet cupping, Baduanjin, blood letting, auricular acupuncture, music, massage, Qi gong, moxibustion, relaxation therapies, biofeedback, device-guided breathing, yoga and tai chi) based on the inclusion criteria. The quality of evidence was generally low, and weak recommendations were given for most therapies except massage and acupuncture plus antihypertensive drug. Based on the analyzed evidence, massage and acupuncture plus antihypertensive drug could benefit people who want to lower their BP and do not have contraindications for massage and acupuncture plus antihypertensive drug. DISCUSSION/STRENGTH: The GRADE approach makes this review a unique reference for people who are considering the grade of quality of evidence in systematic reviews, the balance of desirable and undesirable consequences and the strength of recommendations to decide which intervention should be used to reduce BP. LIMITATIONS: Many non-drug therapies were excluded due to the low methodological quality of their systematic reviews, and only 14 therapies were evaluated in this review. As no patient-important outcomes were reviewed, surrogate outcomes were used to rate the strength of recommendations. This approach may cause a decrease in evidence quality according to GRADE, but we argue that this is appropriate in the context of this review.

The importance of genetic counseling and genetic screening: a case report of a 16-year-old boy with resistant hypertension and severe hypokalemia.

Liddle's syndrome, an autosomal dominant form of monogenic hypertension, is characterized by salt-sensitive hypertension with early penetrance, hypokalemia, metabolic alkalosis, suppression of plasma rennin activity and aldosterone secretion, and a clear-cut response to epithelial sodium channel blockers but not spironolactone therapy. Here, we describe the case of a 16-year-old boy patient with resistant hypertension (maintain 170-180/100-110 mm Hg after administration four kinds of antiypertensive drugs) and severe hypokalemia. After a series of checks, we exclude primary aldosteronism and renal artery stenosis and other diseases. Finally, the Liddle syndrome was diagnosed because of the DNA sequencing found that the proband's mother and himself had mutations P616L (c.1847 C>T) in the SCNN1B gene. Liddle syndrome should be considered as a cause of hypertension in children or adolescents particularly with suppressed renin activity. Early diagnosis and appropriately tailored treatment avoid complications of long-term unrecognized or inappropriately managed hypertension. Genetic testing has made it possible to make accurate diagnoses and develop tailored therapies for mutation carriers. The role of genetic testing and genetic counseling in establishing the early diagnosis of Liddle's syndrome is important.
