Objective to observe the effects of ulinastatin(UtI)and xuebijing on treatment of burns sepsis after coagulation and systemic inflam-mation. Methods A total of 103 patients diagnosed of sepsis in burn department of our hospital during 2009-01 - 2014-01 were recruited for the study and randomly divided into 2 groups. the control group(51 cases)received conventional fluid resuscitation,mechanical ventilation,renal re-placement,wound dressing or operation,metabolic nutrition support;the treatment group(52 cases)received vein infusion of xuebijing 100 mL, bid on the basis of conventional therapy,ulinastatin 400 000 U intravenous drip,bid,for 10 d. the blood routine,blood coagulation function and in-flammatory reaction index and plasma lipopolysaccharide(LPS),tumor necrosis factor-alpha(tNF-alpha),interleukin-6(IL-6),interleukin-10 (IL-10),C- reactive protein(CRP)and procalcitonin(PCt)of the patients in each group were respectively detected before treatment and after treatment in the 1,3,7,10 days. Results After treatment of coagulation,indexes of blood fibrinogen degradation product(FDP),plasma fibrino-gen(FIB),blood concentration of two D- dimer(D-Dt),platelet and inflammatory reaction index compared were significantly improved compare with those before treatment in both two groups(P < 0.01). In addition,the treatment group showed significantly better effects than the control group, and the difference was statistically significant(P < 0.05). 7 d after treatment inflammation index levels in treatment group decreased more significant-ly compared with the control group,and the difference was significant(P < 0.05). Conclusion Combined application of xuebijing,ulinastatin with auxiliary treatment of post-burn sepsis can reduce the systemic inflammatory response,improve blood hypercoagulable state.

Early diagnosis and timely treatment of hepatic steatosis is very important for controlling the development and improving the prog-nosis of disease.This paper introduces the controlled attenuation parameter (CAP),a novel non -invasive method to quantitatively assess hepatic steatosis.This paper briefly describes the advantages of CAP compared with other methods for detecting hepatic steatosis:CAP is simple,fast,repeatable,and generally accepted by patients.CAP is of great value for early detection of fatty liver.Moreover,this paper re-views the optimal cut -off values of CAP for detection of fatty liver in different studies.CAP can be used to dynamically monitor the progres-sion and regression of fatty liver as a guide to clinical treatment.

Objective To research the efficacy of different dose botulinum toxin A in the treatment of patients with neurogenic detrusor overactivity due to spinal cord injury or multiple sclerosis.Methods The datas of 43 patients with neurogenic detrusor overactivity caused by spinal cord injury or multiple sclerosis which accepted treatment in our hostipal were analyzed.And 38 patients were followed up for 12 weeks,of which 20 cases were treated with 200 U botulinum toxin A,and 18 cases received 100 U botulinum toxin A.The average age of 38 patients was 45.3 years old,and the ratio of famale was higher.The incontinence quality of life(I-QOL)changed from baselin after 6 weeks and 12 weeks was recorded.Resluts The final outcomes showed that the efficacy of botulinum toxin A with 200U was better than that with 100 U according to I-QOL score,and the difference was statistical significance(P <0.05).Conclusion The botulinum toxin A has positive effect on neurogenic detrusor overactivity,and the efficacy of 200 U injection is better than that of 100 U.

Objective To evaluate left atrial function by velocity vector imaging (VVI) in patients with rheumatic mitral stenosis(RMS). Methods Thirty eight patients with RMS and 42 normal controls were studied with VVI analysis software. Peak systolic strain (S), systolic strain rate(SRs), early diastolic strain rate(SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured,and also the SRa peak time delay(Td-SRa). Results Comparing to the controls group, the S, SRs and SRe of all segments were significantly lower(P<0.05). Except the base latero-aorta's SRa, the other segments' SRa were lower (P<0.05). In patients with atrial fibrillation(AF),56% segments had no SRa,and 18.6% had irregular low amplitude movement at late diastole, while 25.4% had discernible positive peak. The base and middle inferior SRa of patients with AF were lower (P<0.05 ) than those of the patients with sinus rhythm. While the Td-SRa of patients was longer than that of control group,especially what of the patients with AF. Conclusions The segmental and globe left atrial function of patients with RMS can be evaluated with VVI.

Objective To evaluate left ventricular torsion and untwisting in patients with coronary artery disease by speckle tracking imaging. Methods Study population consisted of 48 patients, who were diagnosed coronary artery disease initially and received one of coronary arteriography, coronary artery spiral computerized tomography, radionuclide imaging, interventional therapy and bypass surgery. High frame rate (≥60 frame/s) two-dimensional dynamic images of the left ventricular apical long-axis views and parasternal short-axis views at basal and apical levels were recorded. Rotation was measured in the left ventricular short-axis views using 2D strain software. Left ventricular torsion was defined as relative rotation degree between the apical level and basal level. Patients were divided into three groups according to clinic final diagnosis [myocardial infarction ( MIN) group, n = 19; myocardial ischemia ( MIS) group, n =19; normal coronary artery (Contrast) group, n - 10]. Results In MIS group,peak rotation value and rotation value at aortic valve closure in basal level were smaller than those in apical level. Untwisting rate reduced in MIN group. There was linear correlation between left ventricular peak torsion and end-diastolic diameter. There was aslo linear correlation between left ventricular peak torsion and eject fraction. Left ventricular peak rotation at basal level was correlative to eject fraction. Left ventricular untwisting rate had linear correlation to eject fraction, and also had correlation to peak torsion. Conclusions In patients with myocardial ischemia, left ventricular rotation value at apical level is larger than that at basal level. Left ventricular diastolic function is injured severely in patients with myocardial infarction. Untwisting rate is a quantitative index to evaluate myocardial diastolic function.

Objective To assess global systolic function of left ventricle (LV) using speckle tracking echocardiography in patients who are left volumetric overload and to establish the correlativity between strain and left ventricle end-diastolic volume index (LVEDVI). Methods Seventy-seven patients who were left volumetric overload and 30 normal volunteers were enrolled in this study. Respective 3 high frame rate (＞ 100 frames/s) 2D images were recorded from the left ventricular short axis views: the levels of mitral valve annulus, papillary muscle and apex. Three global peak systolic radical strain and strain rate were measured using 2D strain imagirg. LVEDV was obtained by two-plane Simpson method and LVEDVI was obtained by normalized LVEDV with surface body area. Patients were divided into 6 groups: transitionalgroup,group A (LVEDVI:90- 120 ml/m2),group B (LVEDVI: 121 - 150 ml/m2 ),group C (LVEDVI:151 -180 ml/m2),group D (LVEDVI: 181 - 210 ml/m2),and group E (LVEDVI＞210 ml/m2). Patients were divided into two groups by left ventricular ejection fraction (LVEF): group Ⅰ (LVEF≥ 50 % ), group Ⅱ (LVEF＜50％). Results①Compared with normal control group,GRS,GRSr in transitional group showed no change at three short axis levels (P ＞0.05). The above parameters in group A, B and C were significantly higher than those in normal control group( P ＜0. 01 ). In transitional group,group A,B and C,GRS, GRSr of three short axis gradually increased with LVEDVI augmentation. Compared with group A, B,C,D and normal control group,the above parameters of 3 short aixs in group E were decreased( P ＜0. 01 ),which gradually decreased in group C, D, E with LVEDVI augmentation. ②GRS,GRSr of 3 short axis views in group Ⅰ were more significantly high than those in group Ⅱ and normal control group. The parameters above were significantly low in group Ⅱ ( P ＜0.01). ③In group A,B,C,GRS of papillary muscle and apex levels were correlated positively to LVEDVI ( rpapillary muscle = 0.55,0.64,0.76 and rspex = 0. 74, 0. 79,0.71,P ＜0.05) ; In group D, there was no correlativity between GRS of papillary muscle and LVEDVI( r =- 0.35, P ＞ 0.05) while negative correlativity was established in apex level( r = - 0.73, P ＜ 0. 05). In group E,the negative correlativity was found between GRS of papillary muscle and LVEDVI( r = -0. 70,P ＜0.05) while no correlativity was established in apex level( r = - 0.39, P ＞0. 05). GRS of mitral valve annulus was correlated positively to LVEDVI in group A, B( r = 0.79, 0.77, P ＜ 0.05) and had no correlativity in group C,D. The negative correlativity between them was found in group E( r = - 0. 54, P ＜0.05). At LVEDVI: 180- 190 ml/m2 ,GRS of papillary muscle and apex level reach the peak point about 93% and 62% ;GRS of mitral valve annulus level reach the peak about 63% at LVEDVI 150 - 160 ml/m2.Conclusions Radial strain,strain rate change periodically with LV volume overload. Wall motion of left ventricle can be evaluated accurately by speckle tracking echocardiography, which provide useful modality for evaluation cardiac systolic function.

OBJECTIVE: To explore the therapeutic effect of prostaglandin E1 lipid drug-loaded microcapsules(Lipo PGE1) on the earlier diabetic nephropathy (DN). METHODS: 72 cases with early DN were randomly divided into treatment group and control group. The control group were assigned to receive routine hypoglycemic agent,blood pressure controlling, and symptomatic treatment, while the treatment group were given another drip infusion of Lipo PGE1 20ug plus NS100ml q.d besides the routine therapy as in the control group. Both groups received 3 weeks’ course of treatment. The changes of urinary albumin excretion rate(UAER), urinary transferrin(TRF), urinary microglobulin(?1MG)and so on in the 24h urine of the 2 groups before and after treatment were observed.RESULTS: There was great decrease in UAER, TRF and ?1MG in the 24h urine in the treatment group after treatment(P

With the availality of new nucleotides (acid) analogues,the experience of anti-virus treatment has been continuously enriched.However,the problem of drug resistance becomes increasingly significant and the concern of individualized strategies,duration and endpoints of therapy as well as drug-resistance prevention for nucleoside (acid) analogues treatment has become a hot issue.Thus,the European Association for the Study of the Liver updated their guideline on diagnosis and treatment of chronic hepatitis B based on the principles of evidence-based medicine,so as to make it more flexible and practical.We briefly review and compare the updated content of this new guideline,and make analysis combined with the clinical practice,so as to promote the standardization of diagnosis and treatment of chronic hepatitis B.

Emergence and broad spread of chloroquine resistance urge human beings to change drug policy in malaria control and to find more effective new drugs. Nevertheless, chloroquine is still used in the treatment of falciparum malaria in some poor endemic regions due to economic and development reasons. It should be of great significance to un-derstand the mechanism of chloroquine resistance and find the way to reverse it in order to bring chloroquine with high efficacy and low cost back to the first line of the combat to malaria. Advent and development of resistance reversal agents provide a new clue for this purpose. When used together with chloroquine, it can partly restore the efficacy of chloroquine in resistant Plasmodium falciparum. The article summarizes the research progress on chloroquine resistance in P. falciparum and resistance reversers.
