Objective To explore the safety and effects of alpha-lipoic acid (ALA) in patients with ischemic heart failure (IHF). Methods A randomized, double-blind, placebo-controlled trial was designed (ClinicalTrial.gov registration number NCT03491969). From January 2019 to January 2023, 300 patients with IHF were enrolled in four medical centers in China, and were randomly assigned at a 1∶1 ratio to receive ALA (600 mg daily) or placebo on top of standard care for 24 months. The primary outcome was the composite outcome of hospitalization for heart failure (HF) or all-cause mortality events. The second outcome included non-fatal myocardial infarction (MI), non-fatal stroke, changes of left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) from baseline to 24 months after randomization. Results Finally, 138 patients of the ALA group and 139 patients of the placebo group attained the primary outcome. Hospitalization for HF or all-cause mortality events occurred in 32 patients (23.2%) of the ALA group and in 40 patients (28.8%) of the placebo group (HR＝0.753, 95%CI 0.473-1.198, P＝0.231; Figure 1A-1C). The absolute risk reduction (ARR) was 5.6%, the relative risk reduction (RRR) associated with ALA therapy was approximately 19.4% compared to placebo, corresponding to a number needed to treat (NNT) of 18 patients to prevent one event. In the secondary outcome analysis, the composite outcome of the major adverse cardiovascular events (MACE) including the hospitalization for HF, all-cause mortality events, non-fatal MI or non-fatal stroke occurred in 35 patients (25.4%) in the ALA group and 47 patients (33.8%) in the placebo group (HR＝0.685, 95%CI 0.442-1.062, P＝0.091; Figure 1D). Moreover, greater improvement in LVEF (β＝3.20, 95%CI 1.14-5.23, P＝0.002) and 6MWD (β＝31.7, 95%CI 8.3-54.7, P＝0.008) from baseline to 24 months after randomization were observed in the ALA group as compared to the placebo group. There were no differences in adverse events between the study groups. Conclusions These results show potential long-term beneficial effects of adding ALA to IHF patients. ALA could significantly improve LVEF and 6MWD compared to the placebo group in IHF patients.

OBJECTIVE: To observe the clinical efficacy of Daoqi (directing qi flowing) acupuncture technique in Huangdi Neijing (Yellow Emperor's Inner Classic) for moderate-to-severe obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: Sixty patients with moderate-to-severe OSAHS were randomly divided into a Daoqi acupuncture group (30 cases) and a conventional acupuncture group (30 cases, 1 case dropped out). In the Daoqi acupuncture group, Daoqi acupuncture technique in Huangdi Neijing was applied at Shanglianquan (Extra), Fengfu (GV16), and bilateral Lieque (LU7), Zhaohai (KI6); in the conventional acupuncture group, conventional acupuncture was applied at Shanglianquan (Extra), Fengfu (GV16), Yamen (GV15), and bilateral Lieque (LU7), Zhaohai (KI6), Zusanli (ST36), Fenglong (ST40). The treatment was adopted once every other day, 3 times a week, 4 weeks as one course and 3 courses were required totally in both groups. Before and after treatment, the polysomnography (PSG) indexes [apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), longest apnea duration, lowest nocturnal SaO₂ (LSaO₂)], and scores of Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), World Health Organization quality of life-BREF (WHOQOL-BREF) were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the AHI, HI, AI and longest apnea duration were reduced compared with those before treatment in the two groups (P<0.01), the LSaO₂ was increased in the Daoqi acupuncture group (P<0.01); in the Daoqi acupuncture group, the AHI, HI, AI and longest apnea duration were lower than those in the conventional acupuncture group (P<0.05), and the LSaO₂ was higher than that in the conventional acupuncture group (P<0.05). After treatment, the ESS and PSQI scores were decreased compared with those before treatment (P<0.01), while the WHOQOL-BREF scores were increased compared with those before treatment (P<0.01) in the two groups; in the Daoqi acupuncture group, the ESS and PSQI scores were lower than those in the conventional acupuncture group (P<0.05, P<0.01), and the WHOQOL-BREF score was higher than that in the conventional acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the Daoqi acupuncture group, which was higher than 82.8% (24/29) in the conventional acupuncture group (P<0.01). CONCLUSION Daoqi acupuncture technique in Huangdi Neijing can effectively treat moderate-to-severe OSAHS patients, improve the clinical symptoms and quality of life, and has the advantages i.e. simpler acupoints selection and gentler stimulation.

The pain-evoked potential electroencephalogram (EEG) is an effective electrophysiological indicator for pain assessment, yet its extraction is challenging due to interference from background activity and involuntary blinks. Although existing blink artifact-removal methods show efficacy, they face limitations such as the need for reference signals, neglect of individual differences, and reliance on user input, hindering their practical application in clinical pain assessments. In this paper, we propose a novel framework applying adaptive quadrature mirror filter banks (AQMFB) with discrete wavelet transform (DWT) to remove blink artifacts in pain EEG. Unlike traditional DWT methods that apply fixed wavelets across subjects, our method adapts wavelet construction based on the characteristics of EEG. Experimental results demonstrate that AQMFB-DWT outperforms four leading methods in removing blink artifacts with minimal distortion of pain information, all within an acceptable processing time. This technique is a valuable preprocessing step for enhancing the extraction of pain-evoked potentials.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Objective To assess the value of cardiac magnetic resonance(CMR)imaging for predicting adverse left ventricular remodeling in patients with ST-segment elevation myocardial infarction(STEMI).Methods We retrospectively analyzed the clinical data and serial CMR(cine and LGE sequences)images of 86 STEMI patients within 1 week and 5 months after percutaneous coronary intervention(PCI),including 25 patients with adverse LV remodeling and 61 without adverse LV remodeling,defined as an increase of left ventricular end-systolic volume(LVESV)over 15%at the second CMR compared to the initial CMR.The CMR images were analyzed for LV volume,infarct characteristics,and global and infarct zone myocardial function.The independent predictors of adverse LV remodeling following STEMI were analyzed using univariate and multivariate Logistic regression methods.Results The initial CMR showed no significant differences in LV volume or LV ejection fraction(LVEF)between the two groups,but the infarct mass and microvascular obstructive(MVO)mass were significantly greater in adverse LV remodeling group(P<0.05).Myocardial injury and cardiac function of the patients recovered over time in both groups.At the second CMR,the patients with adverse LV remodeling showed a significantly lower LVEF,a larger left ventricular end-systolic volume index(LVESVI)and a greater extent of infarct mass(P<0.001)with lower global peak strains and strain rates in the radial,circumferential,and longitudinal directions(P<0.05),infarct zone peak strains in the 3 directions,and infarct zone peak radial and circumferential strain rates(P<0.05).The independent predictors for adverse LV remodeling following STEMI included the extent of infarct mass(AUC=0.793,95%CI:0.693-0.873;cut-off value:30.67%),radial diastolic peak strain rate(AUC=0.645,95%CI:0.534-0.745;cut-off value:0.58%),and RAAS inhibitor(AUC= 0.699,95%CI:0.590-0.793).Conclusion The extent of infarct mass,peak radial diastolic strain rate,and RAAS inhibitor are independent predictors of adverse LV remodeling following STEMI.

Objective:To investigate the clinical characteristics and prognosis of cryptococcal meningitis patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies.Methods:A total of 216 non-acquired immunodeficiency syndrome (AIDS) related cryptococcal meningitis cases with positive cultures of Cryptococcus, hospitalized at Huashan Hospital, Fudan University during January 2014 and December 2021, were retrospectively included. The serum anti-GM-CSF autoantibodies were detected by enzyme linked immunosorbent assay, and the clinical characteristics and prognosis were compared between patients with and without anti-GM-CSF autoantibodies. Statistical comparisons were mainly performed using the chi-square test or Fisher′s exact test. Cox proportional-hazards model was used to analyze the risk factors associated with prognosis. Results:Among 216 enrolled patients, 23 patients were positive of anti-GM-CSF autoantibodies, with a positive rate of 10.6%. Among 23 patients, seven cases were infected with Cryptococcus gattii, and 16 cases were infected with Cryptococcus neoformans. In the group with positive anti-GM-CSF autoantibodies, 30.4%(7/23) of the patients were infected with Cryptococcus gattii, which was higher than that of 1.6%(3/193) in the group with negative anti-GM-CSF autoantibodies, and the difference was statistically significant ( χ2=38.82, P<0.001). In the group with positive anti-GM-CSF autoantibodies, 30.0% (6/20) had mass lesions with a diameter greater than three centimeters in the lungs, and the one-year all-cause mortality rate was 50.0% (10/20), which were both higher than those of 3.4%(5/145) and 16.1% (29/180) in the negative group, respectively. The differences were both statistically significant (both Fisher′s exact test, P<0.01). Age≥60 years (hazard ratio ( HR)=4.146, P=0.002), predisposing factors ( HR=3.160, P=0.021), epilepsy ( HR=6.129, P=0.002), positive anti-GM-CSF autoantibodies ( HR=2.675, P=0.034), white blood cell count of cerebrospinal fluid (CSF)<100 ×10 6/L ( HR=2.736, P=0.039), the titers of cryptococcal capsular polysaccharide antigen of CSF≥1∶1 280 ( HR=4.361, P=0.009) were independent risk factors for one-year all-cause mortality in patients with cryptococcal meningitis. Conclusions:In non-AIDS related cryptococcal meningitis patients, the positive rate of serum anti-GM-CSF autoantibodies is as high as 10.6%. Patients with anti-GM-CSF autoantibodies could be infected with both Cryptococcus neoformans and Cryptococcus gattii, and they have higher proportion of lung mass lesions than patients with negative anti-GM-CSF autoantibodies. The one-year survival rate decreases significantly in patients with anti-GM-CSF autoantibodies, which is an independent risk factor for the prognosis of cryptococcal meningitis.

OBJECTIVES: This population-based, prospective cohort study investigated the association between glaucoma and mortality in older adults. METHODS: Participants aged 45 years or older at baseline (47.9% male) were enrolled in 2011 for the China Health and Retirement Longitudinal Study (CHARLS). All-cause mortality was observed during 7 years of follow-up. The baseline data were collected in the 2011 CHARLS, and participants were followed up for 7 years (until 2018). The risk of all-cause mortality was investigated using Cox proportional-hazards regression with age as the time scale, adjusting for significant risk factors and comorbid conditions. RESULTS: Among the 14,803 participants included, the risk of all-cause death was significantly higher among people with glaucoma than among those without glaucoma, after adjustment for other confounders (hazard ratio [HR], 1.46; 95% confidence interval [CI], 1.04 to 2.03). In a subgroup analysis based on the mean age of death, among those who were 75 years and older (n=1,231), the risk of all-cause death was significantly higher in patients with glaucoma than in those without glaucoma (HR, 1.89; 95% CI, 1.24 to 1.89). CONCLUSIONS Participants with glaucoma had a higher risk of all-cause mortality, especially those aged 75 years and above. Our findings revealed potential mechanisms underlying an association between glaucoma and all-cause mortality. They also highlighted the importance of glaucoma management to prevent premature death in middle-aged and older adults.

OBJECTIVES: This study evaluated the association between obesity and glaucoma in middle-aged and older people. A population-based retrospective cohort study was conducted using data from the China Health and Retirement Longitudinal Study. METHODS: Glaucoma was assessed via self-reports. Multivariate logistic regression analysis and a Cox proportional hazards model were used to assess the relationship between obesity and glaucoma risk. RESULTS: Older males living in urban areas who were single, smokers, and non-drinkers were found to have a significantly higher incidence of glaucoma (all p<0.05). Diabetes, hypertension, and kidney disease were also associated with higher glaucoma risk, while dyslipidemia was associated with lower risk (all p<0.05). After the model was adjusted for demographic, socioeconomic, and health-related variables, obesity was significantly associated with a 10.2% decrease in glaucoma risk according to the Cox proportional hazards model (hazard ratio, 0.90; 95% confidence interval [CI], 0.83 to 0.97) and an 11.8% risk reduction in the multivariate logistic regression analysis (odds ratio, 0.88; 95% CI, 0.80 to 0.97). A further subgroup analysis showed that obesity was associated with a reduced risk of glaucoma in people living in rural areas, in smokers, and in those with kidney disease (all p<0.05). Obesity also reduced glaucoma risk in people with diabetes, hypertension, or dyslipidemia more than in healthy controls (all p<0.05). CONCLUSIONS This cohort study suggests that obesity was associated with a reduced risk of glaucoma, especially in rural residents, smokers, and people with kidney disease. Obesity exerted a stronger protective effect in people with diabetes, hypertension, or dyslipidemia than in healthy people.

Objective:To explore the mechanism of acupuncture and moxibustion for ulcerative colitis(UC)from the perspective of the P2X7 receptor(P2X7R)-nucleotide-binding oligomerization domain(NOD)-like receptor protein 3(NLRP3)inflammasome pathway. Methods:Sprague-Dawley rats were randomly assigned to a normal(N)group,a model(M)group,a herb-partitioned moxibustion(HM)group,and an electroacupuncture(EA)group.For modeling,the rats drank 4%dextran sulfate sodium for 7 d.Rats in the HM group and EA group received 7 consecutive days of HM or EA at bilateral Tianshu(ST25),respectively.The histopathological change in colon tissue was observed by hematoxylin-eosin(HE)staining;immunofluorescence staining was used to detect the protein expression of related molecules in the colon tissue,and enzyme-linked immunosorbent assay was used to detect the concentrations or contents of related molecules in the serum and colon tissue.Wild-type(WT)and P2X7R gene knockout(KO)mice were used to construct UC models,histopathological changes in the colon tissue were observed by HE staining,and the NLRP3 protein expression in the colon tissue was observed by immunohistochemistry. Results:Compared with the N group,the colon histopathological score in the M group was significantly increased,and the protein expression of P2X7R,NLRP3,apoptosis-associated speck-like protein containing CARD(ASC),Caspase-1,interleukin-1β(IL-1β),and interleukin-18(IL-18)in the colon tissue and the protein levels of IL-1β and IL-18 in the serum were significantly increased(P<0.05).Compared with the M group,the histopathological scores of the colon in the HM group and the EA group were significantly decreased,and the protein expression levels of P2X7R,NLRP3,ASC,Caspase-1,IL-1β,and IL-18 in the colon tissue and the protein level of IL-18 in the serum were significantly decreased(P<0.05).After UC modeling,the colonic mucosal epithelial damage and inflammatory cell infiltration in P2X7R KO mice were less than those in WT mice,and the NLRP3 protein expression in the colon was also decreased compared with that in WT mice(P<0.05). Conclusion:HM and EA at Tianshu(ST25)may inhibit the protein activities of P2X7R,NLRP3,ASC,and Caspase-1 in the colon tissue of rats with UC,thereby reducing the downstream molecules IL-1β and IL-18 in the P2X7R-NLRP3 inflammasome pathway to relieve UC inflammation.
