Investigating the effects and efficacy of self-compassion intervention on generalized anxiety disorders.

BACKGROUND: Generalized anxiety disorder (GAD) is the least successfully treated anxiety disorder. This clinical trial investigated the effects and efficacy of a novel self-compassion intervention in GAD. METHODS: A total of 75 GAD patients were assigned to a self-compassion intervention group (n = 25), a mindfulness intervention group (n = 25), or a treat-as-usual group (n = 25). Patients in the two active groups received eight intervention sessions in two weeks in addition to usual treatment i.e., pharmacotherapy. Primary outcomes were anxiety and worry, assessed at pre-intervention, post-intervention, and three-month follow-up. Secondary outcomes included depression, sleep, as well as self-compassion and mindfulness. RESULTS: Both the self-compassion and mindfulness intervention induced a more rapid decrease in anxiety and depression than pharmacological treatment alone with excellent response and remission rate. Self-compassion intervention also induced a more rapid improvement in sleep quality compared to mindfulness intervention and pharmacological treatment alone. We also presented a mechanism for the self-compassion intervention in which decreased anxiety led to improvement in sleep quality. There was also a higher pleasure, acceptance, and willingness to re-attend in the self-compassion compared to the mindfulness intervention. LIMITATIONS: This study was single blinded and nonrandomized which may bring risks of bias. CONCLUSIONS: Overall, we provided novel evidence that self-compassion intervention is an alternative psychotherapy for GAD with excellent response and acceptability.

A fluorescent terbium-metal-organic framework material for high-sensitivity detection of vomitoxin and oxytetracycline hydrochloride in water.

A unique luminescent lanthanide metal-organic framework (LnMOF)-based fluorescence detection platform was utilized to achieve sensitive detection of vomitoxin (VT) and oxytetracycline hydrochloride (OTC-HCL) without the use of antibodies or biomolecular modifications. The sensor had a fluorescence quenching constant of 9.74 × 106 M-1 and a low detection limit of 0.68 nM for vomitoxin. Notably, this is the first example of a Tb-MOF sensor for fluorescence detection of vomitoxin. We further investigated its response to two mycotoxins, aflatoxin B1 and ochratoxin A, and found that their Stern-Volmer fluorescence quenching constants were lower than those of VT. In addition, the fluorescence sensor realized sensitive detection of OTC-HCL with a detection limit of 0.039 µM. In conclusion, the method has great potential as a sensitive and simple technique to detect VT and OTC-HCL in water.

Comparison of the early clinical efficacy of the SuperPath approach versus the modified Hardinge approach in total hip arthroplasty for femoral neck fractures in elderly patients: a randomized controlled trial.

PURPOSE: To investigate the clinical efficacy and advantages of the SuperPath approach for total hip arthroplasty in the treatment of femoral neck fractures in the elderly population. METHODS: From February 2018 to March 2019, 120 patients were randomly divided into two groups with 60 patients each: the SuperPath group and the conventional group. The results evaluated included the general operation situation, serum markers, blood loss, pain score, hip function and prosthesis location analysis. RESULTS: There was no demographic difference between the two groups. Compared with the conventional group, the SuperPath group had a shorter operation time (78.4 vs. 93.0 min, p = 0.000), a smaller incision length (5.8 vs. 12.5 cm, p = 0.000), less intraoperative blood loss (121.5 vs. 178.8 ml, p = 0.000), a shorter hospitalization time (8.0 vs. 10.8 days, p = 0.000) and less drainage volume (77.8 vs. 141.2 ml, p = 0.000). The creatine kinase level in the SuperPath group was significantly lower than that in the conventional group, while there was no difference in the C-reactive protein level and erythrocyte sedimentation rate level. The visual analog scale score was lower one month postoperatively, and the Harris hip score was higher three months postoperatively in the SuperPath group (p < 0.05). There was no difference in the cup abduction angle or anteversion angle of the two groups. CONCLUSION: We found better clinical efficacy after using the SuperPath approach with less muscle damage, less postoperative pain and better postoperative function than after using the modified Hardinge approach. Trial registration The randomized clinical trial was retrospectively registered at the Chinese Clinical Trial Registry on 31/12/2020 (ChiCTR-2000041583, http://www.chictr.org.cn/showproj.aspx?proj=57008 ).

The hydrogen bond between tryptophan and the host molecule induced fluorescence enhancement.

Tryptophan is one of important amino acids in the human body, therefore its detection is particularly important. The 3,5-bis(4-pyridyl)-4-amino-1,2,4-triazole (BPAT) organic molecule was designed to be used as fluorescence detectors to detect tryptophan molecules for the interaction between the host and the guest. BPAT shows good sensitivity and selectivity towards tryptophan compared with other amino acid molecules. The limit of detection obtained from formula 3δ/KSV is considered to be 5.43 × 10-7  mol/L. We speculated that this change is mainly caused by the hydrogen bond between tryptophan and the host molecule BPAT. This conjecture was verified by the controlled experiments with other host molecules.

The effects of serum ischemia modified albumin on diagnosis of cerebral infarction and vertebral basilar artery stenosis.

OBJECTIVES: Serum ischemia-modified albumin (IMA) is higher in patients with cerebral infarction (CI). In this study, we aimed at studying the association between IMA and CI. METHODS: Patients with CI were divided to severe stenosis group and mild stenosis group according to the stenosis of vertebrobasilar artery. Digital subtraction angiography (DSA) and magnetic resonance imaging (MRI) were used for diagnosis. Cobalt-combined with Albumin test was used to determine the serum IMA levels. Serum IMA levels in patients with CI and healthy volunteers were compared by t test. Receiver operating characteristic (ROC) curve was performed for evaluating the diagnostic efficiency of serum IMA for CI. The correlation between IMA level and the National Institute of Health Stroke Scale(NIHSS) score after treatment was analyzed. RESULTS: Serum IMA levels in patients with CI was increased compared to healthy volunteers(P < .05). Patients in severe stenosis group had a higher serum IMA level than mild stenosis group(P < .05). Serum IMA level at admission was associated with NIHSS score on the 7th day after treatment(P < .05). CONCLUSIONS: Serum IMA level was correlated with vertebrobasilar artery stenosis and  short-term prognosis in patients with acute CI.

Disturbances of Dynamic Function in Patients With Bipolar Disorder I and Its Relationship With Executive-Function Deficit.

Abnormity in brain regional function and inter-regional cooperation have been linked with the dysfunction during cognitive and emotional processing in bipolar disorder (BD) patients. Recent evidences have suggested that brain function is not static but temporal dynamic. In present study, we aimed to characterize the temporal dynamics of regional function and inter-regional cooperation in BD and its relationship with executive dysfunction, an important deficit in BD. Resting-state functional MRI was performed in patients with bipolar I disorder (BDI) (n = 18) and healthy controls (HCs, n = 19). We first assessed local-function temporal variety with dynamic amplitude of low-frequency fluctuation (dALFF). Region with significant inter-groups difference in dALFF was chosen as a seed to calculate inter-regions connective temporal variety with dynamic functional connectivity (dFC). The executive function was measured by Verbal Fluency Test (VFT). The relationship between executive function and brain dynamics were examined. Compared with HC, the BDI group showed decreased dALFF (less temporal variability) in the posterior cingulate cortex (PCC) and decreased dFC between PCC and medial prefrontal cortex (mPFC). The PCC-mPFC dFC was positively associated with VFT in BDI patients, but not in HC. These findings implicated the reduced temporal variability in local region and inter-regions cooperation in BDI, which may be a neural substrate of executive-function deficit in BDI.

miR-26a-5p Regulates Synovial Fibroblast Invasion in Patients with Rheumatoid Arthritis by Targeting Smad 1.

BACKGROUND We studied the expression and effect of miR-26a-5p in synovial fibroblast in patients with rheumatoid arthritis (RA). MATERIAL AND METHODS The synovial tissues of 55 RA patients with total knee arthroplasty performed from January 2016 to December 2016 were collected as the RA group, and 62 patients without RA history amputation or total knee arthroplasty served as the control group. The expressions of miR-26a-5p and Smad 1 mRNA in synovial fibroblast in patients with RA were detected by qPCR; The expression of Smad 1 and TGF-ß1 protein in synovial tissue or synovial fibroblasts was detected by immunoblotting. Transwell assay was used to detect the invasive ability of synovial fibroblasts. RESULTS The expression of miR-26a-5p and Smad 1 in synovial fibroblast in patients with RA were significantly higher than those in the control group (P<0.05). The expression of miR-26a-5p in synovial tissue of RA patients was positively correlated with the expression of Smad 1 mRNA (r=0.8982, P<0.001). The luciferase system showed that miR-26a-5p targeting synovial membrane FLS cells (P<0.05); the expression of MMP-1, MMP-3, MMP-13, and TGF-b1 protein and mRNA in the synovial FLS cells of RA patients was significantly decreased; and the expression of miR-26a-5p was significantly decreased in FLS cells with invasive ability. CONCLUSIONS miR-26a-5p is highly expressed in synovial tissue of patients with RA, and its high expression can improve the invasive ability of synovial fibroblasts by targeting Smad 1 gene and accelerating the progression of RA.

Influence of carotid artery stenting on cognition of elderly patients with severe stenosis of the internal carotid artery.

BACKGROUND: The aim of this study was to investigate the influence of carotid artery stenting (CAS) on the cognition and quality of life of elderly patients with severe stenosis of the internal carotid artery. MATERIAL/METHODS: 65 elderly patients with symptomatic severe stenosis of internal carotid artery were recruited into 2 groups: the pharmacotherapy group (n=29) and the CAS group (n=36). Before surgery and 1, 3, 6, and 12 months after surgery, Montreal cognitive assessment (MoCA) was used for the evaluation of cognition and WHOQOL-BREF was used for the assessment of quality of life. RESULTS: At 12 months after surgery, total MoCA score and WHOQOL-BREF score in the pharmacotherapy group was significantly reduced when compared with those before surgery (P<0.05). In the CAS group, the total MoCA score, scores of attention and delayed recall, and WHOQOL-BREF score increased significantly at different time points after surgery when compared with those before surgery (P<0.05). Moreover, in CAS group, the MoCA score and WHOQOL-BREF markedly increased gradually over time (P<0.05). Compared with the pharmacotherapy group, cognition and quality of life in the CAS group were improved dramatically during the follow-up period (P<0.05). CONCLUSIONS: Severe stenosis of the internal carotid artery is a cause of cognition impairment, and CAS may improve cognition and quality of life.

Influence of stent-assisted angioplasty on cognitive function and affective disorder in elderly patients with symptomatic vertebrobasilar artery stenosis.

BACKGROUND: We aimed to investigate cognitive function and affective disorder in elderly patients with symptomatic vertebrobasilar artery stenosis (SVAS) after stent-assisted angioplasty (SAA) and to explore the potential mechanism. MATERIAL AND METHODS: The study subjects were 26 elderly SVAS patients who were non-responsive to pharmacotherapy and received SAA (study group) and 30 patients receiving intracoronary stent implantation (control group). Montreal cognitive assessment (MoCA), Hamilton depression rating scale (HAMD), and Hamilton anxiety rating scale (HAMA) were used. RESULTS: The total MoCA score, scores of line connection, copying cube, drawing clock, and delayed recall increased significantly in the study group after surgery (P<0.05, P<0.01). In addition, the MoCA score increased over time and the total MoCA score at 12 months was markedly higher than that at 1 month (P<0.05). The scores of HAMD and HAMA decreased dramatically after surgery compared with before surgery in these patients (P<0.01). A comparison at the corresponding period was performed between study group and control group, and it was found that the differences in total MoCA scores and scores of line connection, copying cube, drawing clock, and delayed recall before surgery and at 1 month after surgery were significant (P<0.05, P<0.01). CONCLUSIONS: SAA may improve the visuospatial/executive abilities and delayed recall, as well as the depression and anxiety in patients with SVAS. Larger and controlled trails are needed to investigate the effect of SAA on cognition and affection in these patients.
