ObjectiveTo investigate the predictive value of N-terminal pro-brain natriuretic peptide(NT-proBNP) level on the capacity load of patients with maintenance hemodialysis (MHD).MethodsOne hundred and twenty patients undergoing MHD were divided into two groups according to blood pressure levels:bad blood pressure control group with 72 patients and good blood pressure control group with 48 patients.NT-proBNP levels were detected before and after dialysis,and cardiothoracic ratio,left ventricular mass index ( LVMI ),swelling index,number of occurrences of low blood volume and ultrafiltration volume were measured and compared between two groups.The correlation between NT-proBNP and the above indicators was analyzed.ResultsThe systolic blood pressure,diastolic blood pressure,NT-proBNP before dialysis,cardiothoracic ratio,LVMI,swelling index and number of occurrences of low blood volume in bad blood pressure control group respectively were (159.7±18.2) mm Hg (1 mm Hg =0.133 kPa),(95.3±14.8) mm Hg,(11 837.13±1374.26) ng/L,0.61±0.12,(174.36±21.35) g/m2,2.93±1.72,12cases/week,while the indicators in good blood pressure control group were ( 131.6±17.3) mm Hg,(86.5±13.2) mm Hg,(7649.54±1106.18) ng/L,0.52±0.11,( 151.83±18.94) g/m2,1.02±1.48,26 cases/sweek.There were significant differences between two groups (P ＜ 0.01 ).It was showed that NT-proBNP difference between before and after dialysis had significant positive correlation with ultrafiltration volume(P＜ 0.05).NT-proBNP before dialysis had a significant positive correlation with systolic blood pressure,diastolic blood pressure,cardiothoracic ratio,LVMI and swelling index (P ＜ 0.05 or ＜ 0.01 ),while had obvious negative correlation with the number of occurrences of low blood volume(P ＜ 0.01 ).ConclusionsNT-proBNP level of MHD patients has close correlation with blood pressure,cardiothoracic ratio,swelling index,number of occurrences of low blood volume and ultrafiltration volume.Detecting the level of NT-proBNP can better evaluate the changes of blood volume in dialysis patients,adjust dialysis prescription in time,and ensure the adequacy of dialysis.It has important significance to improve the quality of life of MHD patients.

Objective To investigate clinical characteristics of 48 cases verified to be infected with S.suis type 2.Methods 1.All data of 48 cases suffered from S.suis type2 infection were col- lected and analyzed.2.Pathogenic gene of S.suis type 2,Such as cps 2A,mrp,and sly et al.,were verified by PCR.Results 1.Pathogenic gene of S.suis type 2 were same from those patients and swine.Drug sensitivity test were carried on and showed resistance to tetracycline and streptomycin. 2.All 48 cases had history to butchering and/or direct contacting blood plasma composition of suffer- ing from or dead pigs.People with wound in the skin had higher risk to be infected.3.Four clinical types were classified as general,meningitis.Shock and both shock combined meningitis.Mortality rate was 14.58%.Conclusion 1.S.suis type 2 was the pathogen leading to the infections of 48 cases in this study.The swine of suffering from the disease or dead were the origins of the transmis- sion.2.Main route of infection was butchering or/and direct contacting the plasma composition of be- ing ill or dead pigs.No second generation of patients were found.3.The cases with shock should be treated as early as possible.4.Taking antibiotic were rational used seriously in human being and ani- mals.

Objective To investigate the possibility of taking bees as laboratory animals and establishing the new rapid ag-ing animal model. Methods The bee model was established under environment of high temperature, lack of oxygen, and vibration. The appropriate conditions for establishing the model were investigated by observing the changes of appearance and measuring the activities of the total SOD and GSH-PX in the whole homogenate of bees. Meanwhile, the changes of biopsy were observed. Results Bees aging model could been set up at the conditions of appropriate temperature, hypoxia and noise. The model has obvious indications of aging, such as reduced activity of SOD and GSH-PX, and obviously pathological changes of brain organization and intestinal tissue. The aging indications are not the most seriously and are suit-able for the studies on drug improving the aging indications. Conclusion Being in the enviroment of high temperature (35 ℃), hypoxia and noise for4 hours, can result in the better bee aging model.

By literature survey searching references and parsing prescriptions, the auther has analyze the clinical advantage of Miao medicine in the treatment of symptom heat stranguria. Guizhou Miao medicine Polygonum capitatum has many advantages such as resources and clinical. After companying with Phellodendri Cortex, the compound prescription plays the pharmacological activity of antipyretic and diuretic, especially for the symptom heat stranguria, damp and hot junction based in the bladder.

BackgroundBoth accommodative abnormality and higher order wavefront aberrations associated with near work are interrelated with blurry retinal image.It is very important to investigate the higher order wavefront aberrations in stable and progressive myopic eyes before and after near work. ObjectiveThe present study wasto observe the high order aberration change of myopic eyes before and after computer work upon near work stimulation as well as the relationship of high order aberration changes to types of myopia. MethodsThe case-controlled design was used in this clinical study.Sixty right eyes of 60 subjects were enrolled,including 30 progressive myopias and 30 stable myopias with matched age and gender.Refractive errors of the subjects were completely corrected by the wearing of spectacles.The subjects remained the work for 1 hour in front of a computer monitor with 40 cm distance under the dark environment and nature pupil size,and the height of the eye and monitor center kept the same level.The changes of wavefront aberration in test eyes were measured with Complete Ophthalmic Analysis System before and after 1 hour of continuous computer work.The influences of computer-work and myopia types on wavefront aberration were analyzed in 3,4,5 mm pupil size.Root-mean-square (RMS) of aberrations was calculated as the index of higher order wavefront aberrations.ResultsThere were no significant differences in the higher order wavefront aberrations before and after computer work for the two types of myopic eyes under the 3,4,5 mm pupil.The RMS of higher order wavefront aberrations were similar between progressive myopia and stable myopia under the 3 mm pupil condition.Total higher order RMS,6th-order,5th-order and 3rd-order RMS were significantly higher in progressive myopic group compared with stable myopic group under the 4 mm pupil size ( RMS3:F =5.985,P =0.016 ; RMS5:F =3.975,p=0.049;RMS6:F=8.130,P=0.005:RMST:F=6.493,P=0.012) and 5mm pupil size(RMS3:F=13.132,P=0.000;RMS5:F =4.032,P=0.047 ; RMS6:F =4.393,P=0.038:RMST:F=10.508,P=0.002 ).The spherical aberrations were higher in progressive myopic group under the 3,4,5 mm pupil conditions in comparison with stable myopic group,but these alterations were insignificant between two types of myopias ( P＞0.05 ).Conclusions Higher order wavefront aberrations of progressive myopic eyes is comparable higher than the stable myopic eyes.Computer reading task dose not significantly impact the higher order wavefront aberrations on myopic eyes.
