OBJECTIVE:To optimize the forming technology of Duanxueliu dropping pills.METHODS:The forming technology of Duanxueliu dropping pills was optimized by orthogonal experiment with the type of matrix,the ratio of extractum to base material and the dropping temperature as factors and with RSD(weight variance of pills),the dissolution time,molding ratio of dripping pills as indexes,meanwhile,comprehensive scoring was carried out.The dripping conditions were optimized with dropping distance,dropping speed,the internal and external diameters of the burette as factors and with variation coefficient of pill weight as index.RESULTS:The optimized parameters for the forming technology were as follows:PEG6000 was used as base material with the ratio of extractum to base material at 1∶3 and the dropping temperature at 75 ℃.The optimized dripping conditions were as follows:the dropping distance was 10 cm;the dropping speed was 50～60 drops per minute;the internal diameter of the burette was 5.0 mm and the external diameter of the burette was 3.0 mm.CONCLUSIO-N:This forming technology serves as experimental basis for the preparation of Duanxueliu dropping pills.

Chronic inflammation,oxidative stress and retinal ganglion cell apoptosis play important roles in the development of diabetic retinopathy.Fenofibrate,a peroxisome proliferator-activated receptor α agonist,is used for dyslipidemia.In addition to its lipid-modulating effects,fenofibrate also has antiinflammatory,antioxidant,anti-apoptotic and anti-angiogenesis properties that may be useful to delay the progression of diabetic retinopathy.Some clinical studies have already confirmed that fenofibrate has therapeutic effect on diabetic retinopathy.Further studies the application of fenofibrate in the treatment of diabetic microangiopathy to clarify the safety and efficacy of fenofibrate is of great significance.

Objective To investigate the diagnostic value of urine neutrophil gelatinase apolipoprotein (NGAL) and kidney injury molecule 1 (KIM-1) as markers of CIN,and the effectiveness of hydration therapy in the prevention of CIN.Methods One hundred and twenty patients were randomly divided into control group and treatment group.The patients of treatment group received hydration therapy through intravenous fluid infusion.Urine samples were taken for detecting the value of albumin (mAlb),NGAL,and KIM-1 before surgery (T0),after surgery 12 h (T1),24 h (T2),48 h (T3),72 h (T4) by ELISA assay.The levels of urinary mAlb,Scr,BUN and cystatin C were detected at the same time.Results (1) The urine NGAL/Cr and KIM-1/Cr significantly increased and were more than twice the baseline value at the time of 12 h after PCI in 87 of 120 cases of the participants.There are eight cases occurred CIN (6.67％) and one case occurred in hydration treatment group (1.7％),seven cases were in control group (11.7％).The difference was statistically significant.(2) There were no significant difference in BUN,Scr,mAlb/Cr,Cys-C and GFR between two gToUps (P ＞ 0.05).(3) NGAL/Cr,KIM-1/Cr were elevated at T1 in both groups (P ＜ 0.01).In hydration treatment group,levels of NGAL/Cr and KIM-1/Cr decreased substantially to the level of T0 at T4(P ＜ 0.01),while in the control group they didn't.(4) Area under the ROC curve (AUC) of NGAL/Cr and KIM-1/Cr 12 h after PCI were 0.931 [95％ CI (0.889,0.973)] and 0.811 [95％ CI(0.736,0.886)] respectively (all P＜0.05).Conclusions NGAL and KIM-1 are sensitive and specific indicators for predicting early renal injury induced by contrast medium and can be used for early diagnosis of CIN.Hydration therapy can prevent the contrast agent-induced renal damage.

Objective To investigate influencing factors of perioperative myocardial injury in patients undergone percutaneous coronary intervention (PCI). Methods Ninty one patients with coronary heart disease (including stable angina and unstable angina) underwent PCI, the perioperative myocardial injury incidence were observed prospectively by monitoring the preoperative and postoperative high sensitivity troponin protein levels to investigate the influencing factors of perioperative myocardial injury by Logistic regression analysis. Results There were no statistically significance in perioperative myocardial injury incidence (62.5%vs 68.7%, P=0.618) and perioperative myocardial infarction incidence (29.2%vs 20.9%, P=0.411) between stable angina and unstable angina groups . These factors of perioperative myocardial injury in patients undergone PCI by Logistic regression analysis were analysed, and we found that the influencing factors were the application loading dose rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels and total stent length. Conclusion Application loading dose of rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels are related to perioperative myocardial injury reduction, whereas the total length of the stent is associated with an increased occurrence of perioperative myocardial injury.

Objective To investigate the effect of baseline Left-ventricular ejection fraction (LVEF) on the cardiac resynchronization therapy (CRT). Methods A retrospective analysis of patients with heart failure was performed. Fifty-four patients [aged (59.73 ± 11.61)years, 31 males, 23 females] who underwent CRT/CRTD were divided into 2 groups according to LVEF ( group A, LVEF≤ 35%; group B, LVEF > 35% ). NYHA class, LVEF,CRT respond rates and medical adverse event (MAE) due to worsening heart failure were detected at 3 and 12 months post-surgery. Results The score of NYHA class changing wasn′t different between these two group. Compared to group B, LVEF was markedly increased (5.08 ± 2.81)% vs (2.45 ± 1.80)%, P < 0.05;(5.38 ± 2.92)% vs (2.39 ± 3.53)%, P < 0.05)at 3 and 12 months post-surgery. Similarly, group A owned high CRT response rates(66.1% vs 33.9%, P < 0.05; 81.25% vs 47.83%, P < 0.05) at the both two time points. At 12 months post-surgery , LVED decreased and the MAE was similar in all groups. Conclusion Patients with EF≤ 35% have more increases in LVEF and own high CRT response rates post-CRT.

Objective To compare the CLIP score, the JIS score, and the China staging system (CS) in the prediction of survival of patients with resectable hepatocellular carcinoma (HCC). Methods The Clinicopathologic and follow-up data of 224 patients who underwent hepatic resection for HCC from January 2000 to July 2005 were retrospectively studied. The patient distribution and the survival curve of each staging system were used to compare the ability to stratify and to discriminate prognosis. The likelihood ratio, chi-square test and the linear trend chi-square test were used to compare the homogeneity and the monotonicity of the relationship between stage and mortality rate of each staging system. The increase in the -2 log likelihood statistic on removal of any one staging system was in turn used as a means of ranking the individual staging systems according to their importance within the regression model. The statistical package used was SPSS version 16. 0 and Stata SE version 8.0. Results Based on the China staging system, the percentages of patients categorized as Ⅰa, Ⅰ b, Ⅱa,Ⅱb and Ⅲ a were 14. 3%, 17.4%, 21.9%, 31.7% and 14. 7% respectively, showing excellent stratification ability. However, nearly 81. 6% of the patients were classified as a CLIP score of 0-2, which showed poor stratification ability, and only 3. 1 % of the patients were classified as score 0 category of the JIS scoring system. In the follow-up period, the log-rank test and the corresponding Kaplan-Meier survival curves confirmed each staging system to be able to differentiate patient survival in the different stages. Individual pairwise comparisons revealed inconsistencies across the different staging systems. In particular, using the log-rank test, the JIS scoring system and the China staging system showed significant differences in patient survival on all pairwise comparisons. By contrast, the CLIP scoring system failed to differentiate significantly between score 2 and score 3 patients. The JIS scoring system could identify the best prognostic group who would benefit from curative and aggressive treatments, whereas the discriminatory value of the CLIP score was noted in the intermediate- and advanced-phase HCC patients. The China staging system was shown to have the best homogeneity, overall discriminatory capacity and monotonicity of gradient. The change in the -2 log likelihood statistic on removal of any staging system revealed that for this cohort of patients, the appropriate importance in the ranking of the independent contribution of each factor to the regression model was: CS> CLIP>JIS. Conclusion Among three clinical staging systems, the China staging system had the highest prognostic value, with better stratification and higher discriminatory capacity than the CLIP scoring system and the JIS scoring system for this cohort of patients who received partial hepatectomy for HCC. The CLIP scoring system performed better in identifying the worst prognostic patients.

Objective To compare the accuracy rate of talar osteochondral lesions between the small field of view (FOV) surface coil MR imaging and 2D FSE proton density weighted imaging (2D-FSE-PD),3D-SPACE sequences MR imaging with boot-shaped coil.Methods Totally 43 patients (45 ankles) underwent 3D-SPACE sequence after 2D-FSE-PD sequence scanning using the boot-shaped coil,then the PDWI sequence was scanning after the boot-shaped coil was replaced by the small FOV surface coil at 1.5T MRI.The results of the arthroscopic examinations was regarded as the standard for assessing the accuracy rate of the three methods.Results The accuracy rate of 2D-FSE-PD sequence with small FOV surface coil was 86.67％ (39/45),the accuracy rate of 2D-FSE-PD sequence with boot coil was 60.00％ (27/45),the accuracy rate of 3D-SPACE sequence with boot coil was 68.89％ (31/45).The accuracy rate of small FOV surface coil was higher than those of boot coil used 3D-SPACE sequence (x2 =4.114,P =0.002) and boot coil used 2D-FSE-PD sequence (x2 =8.182,P＜0.001).There was not significant difference between 3D-SPACE sequence using boot coil and 2D-FSE-PD sequence using boot coil (x2 =0.776,P=0.125).Conclusion Compared with the 2D-FSE-PD and 3D-SPACE sequences with boot-shaped coil,the small surface coil scanning with routine sequence can show talar osteochondral lesions better.
