RESUMO

Objective To observe the effects of scalp electroacupuncture (SEA) combined con- straint-induced movement therapy ( CIMT) on movement function of ischemic stroke patients' upper limbs. Methods Totally 80 stroke patients were assigned to four groups according to random digit table, i.e., the routine rehabilitation group, the SEA group, the CIMT group, and the comprehensive intervention group. Patients in the routine rehabilitation group strengthened the training of upper limbs on the affected side by Bobath dominated technology and Brunnstrom assisted technology. Patients in the SEA group received Jiao's SEA combined EA therapy. Those in the CIMT group restricted the upper limbs of the healthy side and strengthened training of the affected side. Those in the comprehensive intervention group used SEA combined CIMT treatment. Fugl-Meyer assessment scale (FMA) , grading of hand function and range of wrist movement were observed before intervention, at week 4 and 12 after intervention, respectively. Results Compared with before treatment in the same group, FMA scores of upper limbs significantly increased, grading of hand function, and range of wrist movement were obviously improved in the 4 groups after 4-week treatment (P <0. 05, P <0. 01). There was no statistical difference in FMA scores of upper limbs or grading of hand function among the four groups. But dorsal expansion of wrist and radial deviation were more obviously improved in the comprehensive intervention group than in the routine rehabilitation group (P <0. 05). Compared with the routine rehabilitation group, FMA scores of up- per limbs increased, grading of hand function and range of wrist movement were obviously improved in the comprehensive intervention group (P <0. 05). Conclusions Routine rehabilitation, SEA, and CIMT showed better rehabilitation effect on movement function of ischemic stroke patients' upper limbs. But ESA combined CIMT showed most obvious effect with earliest effect shown.

RESUMO

BACKGROUND: Ginsenoside Re is an active component in ginseng that confers protection against myocardial ischemia/reperfusion (I/R) injury. Ferroptosis is a type of regulated cell death found in various diseases. PURPOSE: Our study aims to investigate the role of ferroptosis and the protective mechanism of Ginsenoside Re in myocardial ischemia/reperfusion. METHODS: In the present study, we treated rats for five days with Ginsenoside Re, then established the myocardial ischemia/reperfusion injury rat model to detect molecular implications in myocardial ischemia/reperfusion regulation and to determine the underlying mechanism. RESULTS: This study identifies the mechanism behind ginsenoside Re's effect on myocardial ischemia/reperfusion injury and its regulation of ferroptosis through miR-144-3p. Ginsenoside Re significantly reduced cardiac damage caused by ferroptosis during myocardial ischemia/reperfusion injury and glutathione decline. To determine how Ginsenoside Re regulated ferroptosis, we isolated exosomes from VEGFR2+ endothelial progenitor cells after ischemia/reperfusion injury and performed miRNA profiling to screen the miRNAs aberrantly expressed in the process of myocardial ischemia/reperfusion injury and ginsenoside Re treatment. We identified that miR-144-3p was upregulated in myocardial ischemia/reperfusion injury by luciferase report and qRT-PCR. We further confirmed that the solute carrier family 7 member 11 (SLC7A11) was the target gene of miR-144-3p by database analysis and western blot. In comparison with ferropstatin-1, a ferroptosis inhibitor, in vivo studies confirmed that ferropstatin-1 also diminished myocardial ischemia/reperfusion injury induced cardiac function damage. CONCLUSION: We demonstrated that ginsenoside Re attenuates myocardial ischemia/reperfusion induced ferroptosis via miR-144-3p/SLC7A11.

RESUMO

Objective: To investigate the effectiveness and safety of sacubitril valsartan sodium in the treatment of resistant hypertension (RH). Methods: This study is a single-center, prospective, randomized controlled study. According to the inclusion and exclusion criteria, patients with RH who met the criteria were screened, and all patients adjusted their drug treatment (valsartan 80 mg, amlodipine 5 mg, and hydrochlorothiazide 12.5 mg). After 4 weeks of drug elution, the random envelope method was used for random grouping. The treatment group took sacubitril valsartan sodium 200 mg, amlodipine 5 mg, hydrochlorothiazide 12.5 mg, and the control group took valsartan 80 mg, amlodipine 5 mg, and hydrochlorothiazide 12.5 mg for 8 weeks. The 24 h ambulatory blood pressure (BP) and the echocardiography index using the office sphygmomanometer were observed in the patients. Results: A total of 100 patients with RH were included in the two groups, with 50 cases in each group. There were no significant differences in sex, age, or comorbid diseases between the two groups. During the 8-week follow-up, the office BP of the research group were significantly decreased (24.78/17.86 mmHg) compared with those of the control group. In the research group the 24 h average BP, daytime average BP, and nighttime average BP were 144.84/79.82, 147.10/82.06, and 138.67/76.31 mmHg at baseline, and reduced to 128.96/73.32, 131.50/74.94, and 122.11/69.27 mmHg at week 8, which were significantly decreased (P < 0.05 or P < 0.01), and the left ventricular ejection fraction was significantly increased (P < 0.05), compared with the control group. Conclusion: Sacubitril valsartan sodium can effectively reduce BP and improve cardiac function in RH.

RESUMO

This experiment proposed to investigate the efficiency of omega 3 fatty acids from fish that improves autoimmune against myocarditis in the rat. Fish oil was extracted from fresh Tuna fish and performed FAME analysis and mice bioassay. The autoimmune myocarditis was induced by subcutaneous injection of porcine cardiac myosin (PCM) into the footpads of rats on the first and seventh day. Rats were dissected on the 21st day to analyze the histopathological, hemodynamic, echocardiographic factors, and immunohistochemistry expressions. In the study, 73.90% of total fatty acids were recorded. Histological analysis revealed that omega 3 fatty acids administrated groups showed tremendous development in the multifocal myocardia hyaline degeneration and necrosis with inflammatory changes. Moreover, omega 3 fatty acids inhabited the expressions of inflammatory cells (CD4, CD8 and CD11b) and suppressed the level of NF-κB. The echocardiographic factors such as heartbeat, SBP, DBP, levels of LVDs, LVDd, LVPW percentage of LVFS, EF, expression levels of inflammatory cytokines (TNF, IL-1ß, IFN-ɤ, IL-2, and IL-6) also significantly suppressed by omega 3 fatty acids. Hence, the present study proved that consuming fatty acid-enriched fish might be a successful therapy for improving the inflammatory profile, regenerates the heart tissues, and controlled the production of inflammatory cells.

RESUMO

OBJECTIVE: To explore the blood pressure response to different ablation points of renal denervation (RDN) in patients with resistant hypertension. METHODS: A total of 42 cases with resistant hypertension treated by RDN in our center from 2013 to 2015 were retrospectively analyzed. The patients were divided into two groups according to the different ablation points of RDN: the standard treatment group (spiral ablation from near to proximal, with less than 8 points per artery) and the intensive treatment group (from near to far by spiral ablation, with at least 8 points per artery), with 21 patients in each group. The ablation parameters, including points, impedance, actual wattage, and actual temperature, were recorded intraoperatively. Renal angiography was performed again after RDN. Ambulatory blood pressure (ABP) images were taken for all patients at the baseline and 6 months after operation. RESULTS: The mean 24-h blood pressure of the standard treatment group was lower than that of the baseline (24-h systolic blood pressure decreased by 7.4 ± 10.6 mmHg and 24-h diastolic blood pressure decreased by 4.6  ± 6.1 mmHg), and the mean 24-h blood pressure decreased significantly from baseline to 6 months in the intensive treatment group (24-h systolic blood pressure decreased by 27.4 ±  11.4 mmHg, P < 0.0001; 24-h diastolic blood pressure decreased by 10.9 ±  9.6 mmHg, P = 0.005). There was a positive correlation between the decrease of systolic/diastolic 24-hour mean and the number of ablation points used in the procedure. The mean value of systolic and diastolic blood pressure was positively correlated with ablation points at 24-hour (R 2 = 0.777 and 0.633 respectively, P < 0.01). There were no adverse events in either group after the operation and during the follow-up. CONCLUSIONS: RDN could significantly reduce BP in patients with resistant hypertension. Our study showed that the antihypertensive effect appeared to be positively correlated with the number of ablation points.

RESUMO

We investigate the quantum optical properties of strong light-matter interaction between a quantum emitter and a metallic nanoparticle beyond idealized structures with a smooth surface. Based on the local coupling strength and macroscopic Green's function, we derived an exact quantum optics approach to obtain the field enhancement and light-emission spectrum of a quantum emitter. Numerical simulations show that the surface roughness has a greater effect on the near-field than on the far-field, and slightly increases the vacuum Rabi splitting on average. Further, we verified that the near-field enhancement is mainly determined by the surface features of hot-spot area.

RESUMO

In this work, we investigated insecticidal and repellent activities of the essential oils extracted from Ajania nitida and Ajania nematoloba against Tribolium castaneum and Lasioderma serricorne adults. The components of essential oils were analyzed by GC-MS. The main components of A. nitida oil were camphor (20.76%), thujone (18.64%), eucalyptol (13.42%), borneol (8.32%) and those of A. nematoloba oil were ß-pinene (34.72%), eucalyptol (24.97%) and verbenol (20.39%). The results showed that the two essential oils possessed insecticidal and repellent activities against two species of insects. A. nitida oil possessed contact and fumigant toxicity against T. castaneum (LD50 = 30.10 µg/adult and LC50 = 21.07 mg/L air) and L.serricorne (LD50 = 17.51 µg/adult and LC50 = 11.23 mg/L air). A.nematoloba oil showed contact and fumigant toxicity against T. castaneum (LD50 = 102.29µg/adult and LC50 = 69.45 mg/L air) and contact toxicity against L.serricorne (LD50 = 53.43 µg/adult), but no obvious fumigant effect was observed against L.serricorne. Both of essential oils possessed strong repellent activity against T. castaneum and certain repellent activity against L.serricorne. Especially, A. nematoloba oil showed the same level percentage repellency as DEET(the positve control) against T. castaneum. The results indicated that the essential oils of A. nitida and A. nematoloba had the potential to be developed as natural insecticides and repellents for the control of T. castaneum and L.serricorne.

RESUMO

OBJECTIVE: To investigate the effect of the peroxisome proliferator activated receptor-gamma (PPAR-gamma) agonist troglitazone on TGF-beta(1) and fibronectin (Fn) expression in human peritoneal mesothelial cells (HPMCs). METHODS: HPMCs were cultured from human omentum by an enzyme digestion method, growing in medium containing 30 mmol/L D-glucose. TGF-beta(1) and Fn expression were measured in HPMCs in the presence and absence of 15 micromol/L troglitazone. The mRNA expressions of PPAR-gamma,TGF-beta(1) and Fn were determined by semi-quantification reverse transcriptive PCR (RT-PCR). The protein of TGF-beta(1) was determined by enzyme-linked immunosorbent assay (ELISA) and proteins of PPAR-gamma and Fn were determined by Western blot. RESULTS: The mRNA and protein expression of TGF-beta(1) and Fn were significantly increased in HPMCs stimulated with 30 mmol/L D-glucose compared with the control group with F12 media (P<0.01). Obvious decrease of TGF-beta(1) was found in troglitazone(15 micromol/L) treated group compared with group stimulated with 30 mmol/L D-glucose (P<0.05). Exposure of HPMCs to troglitazone reduced the Fn secretion (P<0.05). CONCLUSION: Troglitazone reduced the expression of TGF-beta(1) in HPMCs stimulated by 30mmol/L D-glucose, and reduced Fn production. PPAR-gamma agonists may have a specific role in ameliorating the course of progressive peritoneal fibrosis under long-term peritoneal dialysis states.

RESUMO

Recent studies suggest an anti-inflammatory activity of oxyresveratrol, a stilbene extracted from Cortex mori root used in traditional Chinese medicine that also presents estrogen-like activity. We herein tested the hypothesis that oxyreservatrol exerts an anti-inflammatory effect through its estrogenic-like function. In MCF-7 cells, oxyresveratrol significantly induced proliferation, which was accompanied with estrogen receptor (ER)-mediated transcriptional activation, increased estrogen-targeted gene expression (e.g., pS2, PGR, and CTSD), and increased ERα/ß proteins. The estrogen-like effect of oxyresveratrol was reversed by the ER inhibitor ICI 182780. Strong ER-binding activities of oxyresveratrol were revealed by negative docking scores. The LPS-induced inflammatory response (e.g., upregulated IκB-α phosphorylation, NF-κB nuclear translocation, and cytokine messenger RNA expression) was significantly suppressed in an ER-dependent manner by oxyresveratrol in RAW264.7 cells. These results suggest that oxyresveratrol may function as an ER agonist and modulate NF-κB signaling.

RESUMO

Rab proteins belong to a subfamily of small GTP-binding proteins of the Ras superfamily, which play an important role in intracellular vesicular traffic. In this study, a rab gene was obtained from Euplotes octocarinatus by polymerase chain reaction (PCR) and RT-PCR. The rab gene from macronucleic DNA was 884 bp in length, including non-coding regions and telomeric sequences at both ends. The rab gene from micronuclear DNA (723 bp), lacking of internal eliminated sequences, was identical to rab gene from macronuclear DNA. RT-PCR showed that the opening reading frame of the rab gene was 663 bp long. The rab gene from macronuclear DNA contained an intron of 60 bp at the position from 153 bp to 212 bp of macronuclear DNA. The rab gene had two in-frame TGAs encoding for cysteine in Euplotes octocarinatus. The rab gene used TAG as stop codon, which was the first report in Euplotes octocarinatus. The result of BLAST in NCBI demonstrates that the Rab shares a homology of 49-52% at the amino acid level with Rab1 proteins from a number of other eukaryote, which suggesting that the Rab is a Rab1 homolog. The rab gene was therefore designated Eo-rab-1N (GenBank accession number: DQ105562). The evolution of Eo-rab-1N was analyzed using phylogenetic tree of amino acids sequences of Rab1 obtained from GenBank.

RESUMO

This open-label, multi-dose, single-center, sequential, inpatient study evaluated the effects of a two herb combination drug (T89, Danshen plus Sanqi) on the steady-state pharmacodynamics (PD) and pharmacokinetics (PK) of warfarin in 24 healthy volunteers. Twenty-three subjects attained a stable international normalized ratio (INR) by taking warfarin alone prior to 1-week of added-on use of T89. INR was not increased after the addition of T89 for 7 days (P > .05). The 90% confidence interval (CI) of the geometric mean ratio for maximum plasma concentrations (Cmax) and area under curve (AUClast ) of both R- and S-warfarin when warfarin was administered with or without T89 was within the 0.80 to 1.25 equivalence ratio. These results indicate that T89 has no effect on the steady-state PD and PK of warfarin. Warfarin and T89 dose adjustments are not required when these two drugs are co-administrated in clinical practice.
