An experimental study on flowrate and stability of a type of control valve of 600MW supercritical steam-turbine was presented by measuring instruments of static, dynamic pressure and vibration in self-designed test rig. The investigation shows that flow coefficient is 30% up more than that of the control valve of GX-1 type used widely in domestic power plants now, as small-medium lifts. If the relative lift (h/D) is less than 20%, the valve can always work steadily in all the pressure ratios. When the h/D is between 20% to 24%, big vibration of valve stem occurs if the pressure ratio is between 0.7 to 0.8. When h/D is more than 25%, relatively great vibration happens in a wide range of pressure ratios of 0.4 to 0.85.

Objective To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. Methods A total of 226 advanced schistosomiasis patients with ascites were randomly di?vided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing,while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed,and the quality of life of the patients before and after hospital discharge was assessed. Results The improvement rate,satisfaction degree,and awareness rate of health knowledge of the patients in the experiment group were 93.8%,100%and 97.4%,respectively,which were significantly higher than those of the control group(all P<0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%,respectively,which were significantly lower than those of the control group(both P<0.05). In addi?tion,the average hospitalization days and the hospitalization cost of the experiment group were(12.2 ± 0.7)d and(4 725.0 ± 310.1)Yuan respectively,which were less than those of the control group(both P<0.01). When 6 months after the discharge from hospital,the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group(all P<0.05). Conclusions The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites;meanwhile,it can short?en the hospitalization time and save the hospitalization cost. Therefore,this nursing model is suitable for popularization and ap?plication in the treatment and nursing work of the advanced schistosomiasis assistance.

A new method for the rapid determination of total phthalates (PAEs) in edible oils was developed. The PAEs in edible oils all were hydrolyzed to phthalic acid with tetrabutylammonium chloride (TBAC) as catalyst. Then phthalic acid was extracted by the supramolecular solvent ( SUPRAS) made up of octanol, tetrahydrofuran and aqueous solution, and detected by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS / MS). As a result, hydrolysis time was 10 min. The linear range of phthalic acid was 0. 05- 2. 0 mg / L with a good correlation coefficients ( r > 0. 999). The limits of detection ( LOD) and quantification (LOQ) were 5. 41 and 18. 05 μg / kg, respectively. The recoveries of target analyte at three spiked levels were in the range of 84. 6% - 104. 5% . The repeatability, expressed as relative standard deviation (RSD), was 2. 6% for intra-day and 3. 7% for inter-day. The total PAEs content of 12 edible oils was found in the range of 0. 30-1. 09 mg / kg.

Hepatorenal syndrome (HRS) is a common complication of severe liver disease, with severe conditions and poor prognosis, and causes a great burden to both patients’ family and society. HRS has a complex pathogenesis, and Western medicine treatment has a limited therapeutic effect; therefore, integrated traditional Chinese and Western medicine therapy is a feasible treatment method with a good clinical effect. This article reviews the advances in the diagnosis and treatment of HRS in both modern and traditional medicine, so as to overcome this challenge as early as possible.

Objective To explore the correlation of fatigue with health-promoting lifestyle in the udnergraduate students, so as to provide scientific evidence for the intervention. Methods A cross-section trial was carried out in the undergraduate students from a medical university in Guangzhou. By a self-designed questionnaire, the incidence of fatigue in the undergraduate students was figured out after data processing and statistical analysis. Results A total of 6 100 questionnaires were released, and 5 843 were responded, with a respondent rate being 95.79%. The number of effective questionnaires arrived 5 676. The results showed that the prevalence of fatigue among undergraduate students was 49.6%. The female had a higher risk than the male ( 51.6% vs 45.8%, P<0.01). The prevalence of fatigue in grade 1-3 students was 49.4%, 48.1% and 52.1% , respectively, the difference being insignificant among the three grades (P>0.05). The students with poor level of health-promoting lifestyle had a higher risk of suffering from fatigue (OR=6.647, 95%CI: 4.913-8.993). Conclusion Fatigue is prevalent among the undergraduate students. The incidence of fatigue can be reduced by increasing the level of self-actualization, physical exercise and pressure management.

Aim To assess the impact of morin and acetyl-resveratrol on the oral bioavailability and pharmacokinetics of saquinavir (SQV), a substrate of P-glycoprotein (P-gp), in rats.Methods Twenty rats were randomized into four groups of equal size, including a control group, two intervention groups and a positive control group, and administered orally 30 mg·kg-1 SQV with or without 40 mg·kg-1 morin or acetyl-resveratrol or verapamil (as positive control).The plasma concentrations of saquinavir were determined using a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method, and the PK of SQV was assessed using non-compartmental analysis.Results The PK parameters values of SQV, SQV+morin, SQV+acetyl-resveratrol, SQV+verapamil were as follows: AUC0-t, 381.53 μg·h·L-1,185.53 μg·h·L-1, 360.43 μg·h·L-1, 529.95 μg·h·L-1;AUC0-∞, 409.48 μg·h·L-1, 228.52 μg·h·L-1,446.67 μg·h·L-1, 552.41 μg·h·L-1;Cmax, 110.80 μg·L-1, 86.44 μg·L-1, 139.84 μg·L-1, 423.60 μg·L-1;Tmax, 0.25 h, 0.25 h, 0.25 h, 0.50 h;T1/2, 5.72 h, 5.94 h, 6.78 h, 3.78 h;MRT0-∞, 10.30 h, 9.61 h, 12.30 h, 4.89 h;CL/F, 7.59 mL·kg-1·h-1, 13.88 mL·kg-1·h-1, 7.28 mL·kg-1·h-1, 5.52 mL·kg-1·h-1.Conclusions Multiple peak phenomenon can be observed in the plasma SQV profiles.Morin can significantly reduce the SQV oral bioavailability and affect SQV PK profiles while acetyl-resveratrol cannot significantly affect the SQV oral bioavailability and SQV PK profiles in rats.

Objective To investigate the effects of Epigallocatechin gallate (EGCG) on cardiac protection in diabetic rats and the expression of TGF-1/Smad3 signaling pathway. Methods The influence of clean level 40 SD rats, weight 200-220 g, divided into four random groups:control (Sham) group, diabetic cardiomyopathy model (DC) group, EGCG group, and metformin positive control group (Met).Post 8 weeks of high-fat-diet administration, the rats were injected intraperitoneally with STZ to establish the diabetes cardiomyopathy model. Upon successful model establishment, the EGCG group was intraperitoneally injected with EGCG and the cardiac function of the rats was measured after 28 days of drug administration. Then, the pathological results of the myocardial tissue were analyzed. Triglyceride (TG), total cholesterol (TC), glycosylated hemoglobin (HbA1 c), and blood glucose (FBG) concentrations were also measured. Further, the concentrations of superoxide dismutases (SOD), malondialdehyde (MDA), catalase (CAT), and glutathione peroxidase (GPX) in serum were measured by ELISA. The expression of TGF-β1 and Smad3 in kidney tissues of the rats was measured by Western blotting analysis. Results EGCG could reduce the glucose, lipid, and MDA levels in the blood of the diabetic rats, enhance cardiac systolic and diastolic functions, inhibit TGF-β1 and Smad3 protein expression, enhance the activity of SOD, CAT and GPX, and reduce myocardial tissue fibrosis. Conclusion EGCG can protect diabetic rat hearts by improving metabolic disorder, and its mechanism may be related to the oxidative-stress mediated by the TGF-β1/Smad3 signaling pathway.
