The DNAzyme-catalyzed cleavage of substrate strand is accompanied by the release of numerous UCNPs from MBs. By measuring the fluorescent signal of released UCNPs after the magnetic separation, target miRNA-21 can be detected by the DDMAL system in a linear range from 1.0 fM to 10 nM, with a limit of detection (LOD) of 0.62 fM (3σ). Moreover, the practicability of DDMAL system was demonstrated by using it to evaluate the expression levels of miRNA-21 in cell lines and assay miRNA-21 in human serum.A new approach to the quantitative analysis of parabens (PBs) in cosmetics, based on microextraction by packed sorbent (MEPS) followed by HPLC-UV detection is proposed. The development of optimal conditions for the sample preparation step was carried out in two stages. The potentially important factors that could influence the extraction were screened using the Plackett-Burman design approach, as a result of which, three statistically significant factors were selected from the nine studied. Thereafter, the selected variables were optimized by response surface methodology using a Central Composite Design. Under optimal conditions, the linear ranges for PBs analysis in cosmetic samples were 0.05-4 μg/mL with excellent precision. Limits of detection (LOD) of PBs in cosmetic samples were 2-5 ng/mL, and the extraction recovery ranged from 89 to 105 %. By comparing the chromatograms of the diluted shampoo sample before and after MEPS, the benefits of developed approach were shown. Then it was applied to the analysis of PBs in commercial hair cosmetic products parabens were determined in all samples in which they were indicated on the package and in 1 of 12 samples labeled "paraben-free". Finally, the proposed method was compared with other analytical HPLC-UV methods with various sample pretreatment techniques for PBs analysis in cosmetics described in recent articles. Its sensitivity turned out to be one of the highest, while it is express, automated, meets the principles of green chemistry.As a traditional Chinese medicine of invigorating the kidney, Cuscuta chinensis (CC) can be applied in improving the deficiency of kidney qi in menopausal women and regulating the level of estrogen. Previously, it was found that the ethanol extract of CC had an estrogen-like effect. In this study, the metabolic profile and metabolic pathways of rats in sham, ovariectomized model and CC groups were analyzed using UPLC-TOFMS-based metabolomics and the pattern recognition technology. The serum endogenouse metabolites could be well differentiated in different group, indicating significant differences of metabolic profiles. CC had an reverse adjustment effect on 14 differential metabolites of ovariectomized rats, including sinapyl alcohol, deoxycholic acid, prostaglandin B2, prostaglandin I2, dihydrosphingosine, choline, pentadecanoic acid, arachidonic acid, 1-stearoyl-Sn-Glycerol-3-Phosphocholine, palmitoleic acid, palmitic acid, vaccenic acid, oleic acid and stearic acid. Furthermore, these differential metabolites were categorized into several major pathways, such as biosynthesis of unsaturated fatty acids, lycerophospholipid metabolism and arachidonic acid metabolism. Therefore, it could be concluded that the estrogen-like effect of CC was related to the lipid metabolism to some extent. The research results provide useful help for the in-depth research and development of CC.The COVID-19 pandemic has led to abrupt changes in the delivery of substance use treatment, notably the adoption of telehealth services and a departure from mandatory urine drug screens (UDS). Amid current circumstances, the UDS, which had evolved to signal a "successful" recovery, no longer seems feasible, safe, or necessary. Even prior to the pandemic, the UDS had notable drawbacks, including sending a message of mistrust and hierarchy, potentially causing psychological trauma, and incentivizing falsification. Nonetheless, certain patients may state that they depend on the UDS for motivation or structure while some providers may rely on it to discover which patients are struggling. While a combination of self-report and UDS is generally regarded as the strongest measure of substance use among patients, our experiences caring for patients without the results of the UDS during the COVID-19 pandemic have forced us to examine the use of other measures to define a successful recovery. Complete abstinence may not be the goal for all patients and those who achieve abstinence may have additional goals worth supporting. While the UDS will likely be incorporated back into our treatment plans, we suggest unseating it as the centerpiece of substance use care and discovering additional methods of measuring our patients' outcomes in less traumatizing and more patient-centered ways.
Glucose and lipid metabolism are major prognostic indicators of coronary heart disease. The ratio of plasma glycosylated hemoglobin A1c (HbA1c) to apolipoprotein A-l (ApoA-l) is an indirect measure of insulin resistance. The study aimed to evaluate whether the HbA1c/ApoA-1 ratio can predict the prognosis in patients with the acute coronary syndrome (ACS).

A total of 476 ACS patients diagnosed by coronary angiography were enrolled in this longitudinal, observational, retrospective study. SBI-0640756 Plasma HbA1c, fasting blood glucose and lipid profile were measured. Patients were stratified according to the tertiles of HbA1c/ApoA-l levels. Cox proportional hazard model was used to examine the predictive value of HbA1c/ApoA-l for study endpoints. The association between the Log HbA1c/ApoA-l ratio and major adverse cardiovascular events (MACEs) was estimated using multiple logistic regression. Baseline characteristics showed a mean age of 66±8 years, and 52.5% were hypertensive, 26.8% diabetic, and 54.5% current or prior smokers. During a mean follow-up period of 22.3±1.7 months, 59 deaths occurred. After adjusting for age, gender, smoking, hypertension, diabetes, and coronary artery disease severity, patients in the highest HbA1c/ApoA-l ratio tertile had a 4.36-fold increased risk of mortality compared with those in the lowest tertile. The multivariate logistic regression showed that the Log HbA1c/ApoA-l ratio was associated with MACEs (Odds ratio 2.95, p=0.013).

After adjusting for traditional cardiovascular risk factors and ACS severity scores, the HbA1c/ApoA-1 ratio remained an independent predictor of all-cause mortality and MACEs in the ACS patients undergoing angiography.
