As a common mental disorder, depression is one of the leading causes of disability around the world. Clinical studies have shown that acupuncture is an effective therapy without obvious side effects compared to limited efficacy and adverse reactions of drug therapy, cognitive behavioral therapy, and neuromodulation technology in treating depression. The objective of this review is to systematically evaluate whether acupuncture therapies for depression are safe and effective in order to provide a high-quality reference for clinical trials of acupuncture. A systematic search of the literature was carried out through bibliographic search engine PubMed. Subsequently, the study design, intervention methods, control group, results, and safety of acupuncture were analyzed. The results showed that acupuncture as an adjunct to antidepressants or as a single treatment can exert a positive impact on patients' depressive symptoms. Compared with antidepressants, acupuncture has the advantages of fast onset and long-term efficacy in the treatment of depression, and can enhance the efficacy of antidepressants. Moreover, the efficacy and safety of acupuncture in the treatment of depression maybe related to the qualification of the acupuncturist, the selection of acupoints, and intervention measures.  相似文献

Infection is a common complication of leukemia patients undergoing chemotherapy. Blood culture results are often needed to guide clinical use, but repeated sampling is often necessary to improve the positive rate and eliminate contamination. The purpose of this paper is to find predictive factors of blood culture results among clinical and laboratory indicators and try to establish a prediction model, so as to better choose the time of blood culture examination, predict the results, and better guide clinical treatment. We retrospectively collected clinical and laboratory data of febrile acute leukemia patients undergoing chemotherapy. The samples were randomly assigned to the training set and the validation set, and the prediction model was constructed from the training set. The calibration curve was made in the validation set and the Hosmer-Lemeshow test was performed to evaluate the prediction performance of the prediction model. A total of 229 patients were included. Univariate and multivariate analyses suggested that temperature at fever and procalcitonin were variables of significant difference between positive and negative blood culture patients. The sensitivity of the 2 variables for predicting blood culture results was high, but the specificity was low. In the process of external validation, the predictive ability of the constructed prediction model to the blood culture results was low. This study identified clinical and laboratory parameters associated with blood culture outcomes, but the predictive model established has low predictive accuracy in external validation.  相似文献

BackgroundCD137, a member of the tumor necrosis factor receptor superfamily, has been reported to be expressed highly in patients with acute coronary syndromes. However, limited information is available on the relationship between CD137 expression and complex stenosis morphology in patients with acute coronary syndromes.MethodsOur study included normal controls (n = 50), patients with stable angina (SA) (n = 80) and patients with acute coronary syndromes (ACS), including unstable angina (UA) (n = 70) and acute myocardial infarction (AMI) (n = 100). The expression of CD137 in peripheral monocytes was analyzed by flow cytometry. Serum soluble CD137 (sCD137), MMP-9 and MMP-3 levels were measured by enzyme-linked immunosorbent assay kit. All coronary stenoses with ≥ 50% diameter reduction were assessed by angiographic coronary stenosis morphology.ResultsPatients with ACS(n = 170) showed a significant increase of CD137 [23.6 ± 5.7 mean fluorescence intensity (MFI)] expression in peripheral monocytes compared with control (8.4 ± 2.6 MFI) and SA group (7.9 ± 2.1 MFI) (p < 0.001). sCD137 also showed higher level in patients with ACS(30.2 ± 8.7 ng/ml) than in control (6.2 ± 1.8 ng/ml) and SA group (7.1 ± 2.1 ng/ml) (p < 0.001). Serum MMP-3 and MMP-9 in patients with ACS were 2-times greater than those in control and SA group. A positive correlation was found between MMP-9, MMP-3 and CD137 expression in peripheral monocytes as well as sCD137 levels. An obvious correlation was also observed between soluble or membrane-bound CD137 expression and complex coronary stenoses (r1 = 0.5548, r2 = 0.4652, and p < 0.001). In the logistic regression model, the independent predictors of ACS were sCD137 (odds ratio 2.671, 95% CI 1.718–4.153, P = 0.000), MMP-9 (1.431, 1.043–1.964, P = 0.026) and MMP-3 (1.368, 1.038–1.817, P = 0.018).ConclusionPatients with ACS showed significantly positive correlation between CD137 expression and complex coronary stenosis morphology. We speculate that the increased CD137 expression might represent or reflect an instability of atherosclerotic plaques in patients with ACS.  相似文献

Objective

Increasing evidence show that serum pregnancy-associated plasma protein-A (PAPP-A) and OX40 ligand (OX40L) expression have been implicated in acute coronary syndromes (ACS). We investigated the relationship between PAPP-A level and OX40L in serum and membrane-bound OX40L in patients with ACS.

Methods

The present study included normal controls (n = 30), patients with stable angina (SA) (n = 60) and patients with ACS, including unstable angina (UA) (n = 50) and acute myocardial infarction (AMI) (n = 30). Serum concentrations of PAPP-A and soluble OX40L (sOX40L) were determined with Elisa, whereas the expression of OX40L on monocytes were analyzed with flow cytometry.

Results

The expression of OX40L in peripheral monocytes in patients with UA [25.6 ± 5.5 mean fluorescence intensity (MFI)] and AMI (29.4 ± 6.3 MFI) were significantly higher than those in patients with SA (10.6 ± 2.8 MFI) and controls (11.1 ± 3.5 MFI). Both sOX40L and PAPP-A in patients with UA (15.7 ± 4.9 ng/mL, 25.4 ± 6.8 μg/mL, respectively) and AMI (17.1 ± 5.3 ng/mL, 26.3 ± 5.6 μg/mL, respectively) were significantly higher than those in patients with SA (3.4 ± 1.4 ng/mL, 9.6 ± 2.1 μg/mL, respectively) and controls (3.9 ± 1.3 ng/mL, 8.5 ± 2.8 μg/mL, respectively) (P < 0.001). Interestingly, a positive correlation was found between sOX40L, membrane-bound OX40L and serum PAPP-A levels (r1 = 0.54, r2 = 0.51; P < 0.0001). Both serum and membrane-bound OX40L and PAPP-A levels significantly correlated with complex coronary stenosis (r1 = 0.56, r2 = 0.55, r3 = 0.40; P < 0.001).

Conclusion

PAPP-A level was significantly related to soluble and membrane-bound OX40L in patients with ACS. Enhanced level of serum PAPP-A and sOX40L might represent a prognostic marker for coronary disease activity.  相似文献

The ubiquitous prevalence of pharmaceuticals and personal care products (PPCPs) in water has aroused enormous public concerns. The development of promising materials for eliminating such contaminants in the water environment has attracted extensive attention in the scientific community. In this study, three (350 °C, 450 °C, and 600 °C, respectively) pyrolytic conditions were developed to prepare biochars (BCs), which were mainly prepared from the wastes of the overgrown plants (i.e., vallisneria natans, potamogeton malaianus, phragmites australis, potampgeton crispus, and river sediment additional). BCs were thoroughly characterised by various important properties (i.e., porosity and superficial functional group) and applied to remove diclofenac sodium (DS) drug from water media. Results indicated that the BCs adsorption capacity were remarkably improved when pyrolytic temperature was 450 °C and the adsorption equilibrium could be reached after 4 h (with BCs of 0.12 g/L and DS concentration of 12 mg/L). Batch adsorption experiments demonstrated a fit of Pseudo-second order (R2 = 0.992-0.996) and the Langmuir adsorption isotherm (R2 = 0.981-0.989) was suitable. The thermodynamic parameters derived from the fitting procedure point out the adsorption processes were all spontaneous and endothermic. The overall adsorption mechanism was regarded as pore filling, π-π interaction, van der Waals force, and π-electron attraction. This study stress out the main DS adsorption behavior using the above-mentioned materials was chemisorption predominated, but the adsorption capacity differs with different material properties. The prepared BCs can serve as potential carbonaceous porous adsorbents for removing DS from water media.  相似文献
