ABSTRACT

Objective@#To explore the effect of different air pressure treatment time on preventing deep vein thrombosis in severe chronic bedridden patients.@*Methods@#This is a prospectie, randomized and controlled study. A total of 120 patients with severe chronic bedridden were randomly divided into normal group and experimental group 1, group 2, with 40 cases in each group. The normal group received 30 min every time, and group 1 received 1h,and group 2 received 2h. To observe the incidence of DVT within 15 days, the blood flow velocity of deep femoral vein before and after the first treatment, and the incidence of deep tissue injury.@*Results@#There was no significant difference in the incidence of DVT among the three groups (P> 0.05), but the incidence of DVT in test group 1 was 5.0% (2/40), 2.5% (1/40) and 12.5% (5/40) compared with the conventional group. Compared with before treatment, the blood flow velocity of deep femoral vein in the three groups increased significantly after treatment (t=1.475、t=2.881、t=4.027, all P < 0.05), but after treatment, the blood flow velocity of deep femoral vein in the conventional group (20.41±1.37) ml/s, the experimental group 1 and the experimental group 2 were (22.39±2.22) ml/s and (22.51±1.73) ml/s, respectively, which were significantly faster than that of the conventional group. There were significant differences (t= 3.086、t= 3.662, all P < 0.05).(3) The incidence of deep tissue injury in experimental group 2 was 20.0% (8/40), which was 2.5% (1/40) and 5.0% (2/40) higher than that in conventional group and experimental group 1 respectively (χ2=6.135、χ2=4.114, all P<0.05).@*Conlousion@#On the basis of conventional barometric therapy, it can be extended to 1 h/time, 3 times/d, which can significantly increase the blood flow velocity of deep femoral vein, reduce the incidence of DVT, and do not increase the incidence of skin pressure injury in patients with chronic bed-rest.

ABSTRACT

Stereo-electroencephalography (SEEG) is widely used to record the electrical activity of patients' brain in clinical. The SEEG-based epileptogenic network can better describe the origin and the spreading of seizures, which makes it an important measure to localize epileptogenic zone (EZ). SEEG data from six patients with refractory epilepsy are used in this study. Five of them are with temporal lobe epilepsy, and the other is with extratemporal lobe epilepsy. The node outflow (out-degree) and inflow (in-degree) of information are calculated in each node of epileptic network, and the overlay between selected nodes and resected nodes is analyzed. In this study, SEEG data is transformed to bipolar montage, and then the epileptic network is established by using independent effective coherence (iCoh) method. The SEEG segments at onset, middle and termination of seizures in Delta, Theta, Alpha, Beta, and Gamma rhythms are used respectively. Finally, the K-means clustering algorithm is applied on the node values of out-degree and in-degree respectively. The nodes in the cluster with high value are compared with the resected regions. The final results show that the accuracy of selected nodes in resected region in the Delta, Alpha and Beta rhythm are 0.90, 0.88 and 0.89 based on out-degree values in temporal lobe epilepsy patients respectively, while the in-degree values cannot differentiate them. In contrast, the out-degree values are higher outside the temporal lobe in the patient with extratemporal lobe epilepsy. Based on the out-degree feature in low-frequency epileptic network, this study provides a potential quantitative measure for identifying patients with temporal lobe epilepsy in clinical.

ABSTRACT

PURPOSE: The aim of this study was to investigate the association of telomere length with breast cancer risk. We simultaneously explored the association between telomerase reverse transcriptase gene polymorphisms and telomere length. METHODS: We used real-time quantitative polymerase chain reaction to measure relative telomere length (RTL) in genomic DNA extracted from peripheral blood from 183 breast cancer cases and 191 healthy controls. Genotyping was performed using the Sequenom MassARRAY platform. RESULTS: Our results show that breast cancer patients had significantly shorter RTLs than control subjects (p 40 years (OR, 2.41; 95% CI, 1.31–4.43; p=0.005), body mass index ≤24 kg/m2 (OR, 2.81; 95% CI, 1.55–5.10; p=0.001), and postmenopausal women (OR, 3.94; 95% CI, 1.63–9.51; p=0.002), respectively. In addition, individuals with the AA genotype of rs2853677 have longer telomeres than those of breast cancer patients with the AG genotype (p=0.011). CONCLUSION: Our results suggest that shorter RTL was associated with an increased risk of breast cancer. An association was found between the AA genotype of rs2853677 and longer RTLs in the case group. Functional studies are warranted to validate this association and further investigate our findings.

ABSTRACT

OBJECTIVE:To study the effects of spirulina kinase(SPK)on the vascular endothelial function of model rats with atherosclerosis. METHODS:60 rats were randomly divided into normal control group(distilled water),model group(distilled wa-ter),positive control group(simvastatin,0.005 g/kg)and SPK low-dose,medium-dose,high-dose groups(80,160,320 U/kg). Except for normal control group,rats in other groups were induced for model of atherosclerosis. All groups were intragastrically ad-ministrated relevant medicines at the same time,once a day for consecutive 12 weeks. Total cholesterol(TC),triglyceride(TG), low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α) contents in serum of rats were measured. And the changes of thoracic aortic endothelium morphology were ob-served by HE staining. RESULTS:Compared with normal control group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in model group were increased(P<0.01),HDL-C content in serum was decreased(P<0.01);vascular endothelial cells fell off, intimal proliferation projected into the lumen,smooth muscle cell proliferated and disordered,medium film elastic fiber disintegrat-ed and fractured. Compared with model group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in administration groups were decreased(P<0.05 or P<0.01),HDL-C content in positive control group and SPK medium-dose,high-dose groups was in-creased (P<0.05). Vascular endothelial cell morphology was improved significantly in administration groups,in which,vascular endothelial cells were structurally intact in SPK medium-dose,high-dose groups,inner membrane was basically smooth;medium smooth muscle cells arranged slightly disordered in SPK medium-dose group. Compared with normal control group,there were no obvious changes. CONCLUSIONS:SPK shows obvious lipid-lowering and anti-inflammatory effects,it can protect vascular endo-thelial function. The mechanism may be related to reducing TC,TG,LDL-C,HDL-C,IL-6,TNF-αcontents and increasing HDL-C content in serum.

ABSTRACT

OBJECTIVE:To study the anti-oxidative effects of spirulina kinase (SPK) in vitro. METHODS:The methods of phenanthroine-Fe2+ oxidation method,DPPH and auto-oxidation of pyrogallol were used to measure the effects of different concen-trations of SPK on scavenging hydroxyl (OH-) free radical,DPPH free radical and superoxide anion (O2-) free radical;IC50 of SPK was calculated. Prussian blue reaction was used to determine total reducing ability(by absorbance)of different concentrations of SPK to Fe3+. Vitamin C(VC)was used as positive control in above trials. RESULTS:SPK could eliminate the OH-free radical, DPPH free radical and O2- free radical in concentration-dependant manner,and the maximum elimination rate of SPK to OH- free radical and DPPH free radical were 86.82% and 78.98%(IC50 were 54.31,0.636 g/L),which were higher than VC (64.77%, 73.49%). The maximum elimination rate of SPK to O2- free radical was 78.31%(IC50 was 3.918 g/L),which was lower than VC (94.14%). In reducing ability test,SPK improved absorbance in reducing ability test system,and maximum absorbance was simi-lar to VC in concentration-dependant manner. CONCLUSIONS:SPK has obvious anti-oxidant activities in vitro.
