Objective To study the effect of dialysis adcquacy,microinflammation and residual renal function on nutritional status of hemodialysis patients.Methods One hundred and fourteen patients were enrolled in this study.Kt/V,?_2-MG and serum iPTH were measured as markers of hemodialysis adequacy.Nutritional evaluation included MQSGA,Alb,Hb,TF,IGF-1,IGFBP-3 and anthropometrics such as HGS,BSF,TSF,MAC,MAMC and AMA.Serum IL-6,TNF-?and CRP were detected to assess microinflammation.Urinary volume of 24 hours was measured to investigate the residual renal function (RRF).Results (1)There were different correlations and regressive associations of Kt/V,iPTH and?_2-MG with HGS,MAMC,AMA,Alb,Hb,nPCR,IGF-1 and MQSGA respectively.(2) There were significant correlations and regressive associations of RRF to HGS,TSF,MAMC,Alb,nPCR and IGF-1 within the first year of hemodialysis.(3) There were different correlations and regression relationships of IL-6,TNF-?and CRP with HGS、MAMC、AMA、Alb、TSF、Hb、nPCR、IGF-1 respectively.(4) Multivariate analysis showed that Kt/V,iPTH,IL-6, TNF-?,?_2-MG and RRF were influencing factors,among them,Kt/V,iPTH,IL-6 and TNF-?were independent predictors of nutritional status.Conclusions Hemodialysis adequacy and micruinflammation may impact on nutritional status.Residual renal function may be involved in nutritional status in the first year of hemodialysis.Kt/V,iPTH,IL-6 and TNF-?are independent factors affecting nutritional status.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

OBJECTIVETo observe the clinical effect of combined treatment with safflor yellow powder injection and benazepril in treating patients with diabetic nephropathy (DN).

METHODSSeventy-six patients with DN were randomly assigned to the treatment group (39 cases) and the control group (37 cases). Conventional treatment for lowering blood glucose was given to both groups, but to the control group 10 mg benazepril was given orally once a day additionally, while to those in the treatment group the same dosage of benazepril po. and 150 mg/d of safflor yellow powder injection by adding in 250 mL 0.9% normal saline for intravenous dripping. The therapeutic course for them all was 15 days, and all patients received two courses with an interval of 5 days. Changes of clinical symptoms, urinary albumin excretion rate (UAER), blood and urinary levels of beta2 -microglobulin (beta2 -MG), urinary level of alpha1-microglobulin (alpha1 -MG), D-dimer (D-D) and plasma fibrinogen (FIB) were observed.

RESULTSThe total effective rate in the treatment group was higher than that in the control group (84.62% vs 59.45 %, P < 0.05). The total score of syndrome in the treatment group was lower than that in the control group (P < 0.05). Levels of UAER, 132-MG in serum and in urine, alpha1-MG in urine were decreased significantly after after 2 courses of treatment in both groups, showing significant difference as compared with before treatment (P < 0.05 or P <0.01), and the decrements were more significant in the treatment group than those in the control group (P <0.05); while decrease of FIB, D-D only happened in the treatment group (P <0.01), so the post-treatment data in the treatment group were significantly lower as compared with those in the control group (P <0.01).

CONCLUSIONCombined therapy with safflor yellow injection and benazepril is superior to benazepril alone in reducing urinary albumin, improving renal function and blood hyperviscosity manner for patients with DN, suggesting the combination of the two could play their respective superiorities and act in cooperation for retarding the progression of DN.

Objective To evaluate the clinical efficacy and safety of amiodarone in the treatment of acute myocardial infarction combined with atrial fibrillation.Methods A total of 51 patients with acute myocardial infarction and atrial fibrillation were recruited from January 2012 to October 2014 in our hospital.And they were randomly divided into treat-ment group ( n=26 ) and control group ( n=25 ) .Patients in the treat-ment group were treated with amiodarone 100 mg +0.9%NaCl solution 20 mL by intravenous injection within 6 min and followed by amiodarone 0.5 -1.0 mg? min-1 by intravenous drip until back to sinus rhythm. Patients in the control group were treated with cedilanid 0.4 mg +5%glucose 20 mL by intravenous injection within 5 min.The data of atrial fibrillation control rate in the first 24 hours, the sinus rhythm sustain rate in the first month and adverse drug reactions were compared between the two groups.Results The artial fibrillation control rate was 53.8%and 24.0% in the treatment and control group respectively , indicating treatment group was significantly higher than control group ( P<0.05 ) . The sinus rhythm sustain rate in treatment group was significant higher than that in control group ( 88.5% vs 48.0%, P <0.05 ) .And the incidence of adverse drug reactions in the treatment group were much lower than that in the control group (7.6%vs 40.0%, P<0.05).Conclusion Amiodarone is superior to cedilanid in the treatment of patients with acute myocardial infarction combined with atrial fibrillation for the aspect of clinical efficacy and safety.

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.
