Three hundred and twenty cases were accepte d to the study, in which 200 cases were treated by Niaoshitong pill and 120 case s by Shilintong tablet as control. The effect of both groups was observed. Resul t 107 cases (53.5 % ) were cured, 53 cases(26.5 % ) effective, the total effe ctive rate being 80.0 % in the treatment group, and 27 cases(24.5 % ), 42 cas es (38.2 % ), and 62.7 % respectively in the control group. In a open group of 120 cases ,54 cases (45.0 % ) were cured, 44 cases (36.6 % ) were effective , the total effective rate being 81,6 % .Conclusion Niaoshitong pill can mark edly improve the clinical symptoms and exerts a strong lithagogue effect. It can promote the elimination of calculi after external blast lithotrity or ureterosc opic lithotrity, prevent the formation of 'stone street', and reduce the strictu re formed by the damage of ureter.

Objective To investigate the effect of surfactant protein A (SP-A) on the production of MIP-2 and binding activity of NF-?B in rat tubular epithelial cells, and evaluate its possible role in renal inflammation. Methods Confluent cultures of NRK-52E cells (a renal tubular epithelial cell line of rat origin) were pretreated with various concentrations of SP-A(0 to 80 ?g/ml) and stimulated by lipopolysaccharide (LPS) (10 ?g/ml) with 2% serum. MIP-2 expression was measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). The effect of SP-A on NF-?B binding activity was assessed by electrophoretic mobility shift assay (EMSA). Results MIP-2 mRNA and protein was expressed and up-regulated in NRK-52E cells stimulated by LPS. The expression of MIP-2 was down-regulated by SP-A. NF-?B binding activity was inhibited by SP-A in a concentration-dependent manner. Conclusion SP-A binding activity and down-regulates the expression of MIP-2 in renal tubular epithelial cells, which may play an important role in the modulation of renal tissue inflammation.

OBJECTIVETo study retrospectively 20 hip revison patients treated by cementless total hip arthroplasty with structural allograft.

METHODSTwenty patients suffering from aseptic loosening of an uncemented cup complicated by a large defect underwent cementless total hip arthroplasty with structural allograft and were followed up for at least 5 years. Clinical results were evaluated by Harris score and leg length measurements. Radiographic analysis included implants migration, graft absorbance, osteolysis and liner wear.

RESULTSNo cup loosening or graft reabsorption was found at final follow-up. Clinical improvements in pain and functional status were demonstrated during the follow-up period. The mean Harris hip scores improved from 29 preoperatively (range 20-41) to 81 postoperatively (range 73-89).

CONCLUSIONOur study shows that cementless total hip arthroplasty with allograft is a good way for massive defect in acetabular bone stock.

Objective: To explore the influencing factors of slow blood flow phenomenon after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods: Clinical and PCI angiographic data of 488 patients, who were diagnosed as AMI and received primary PCI in our hospital from Jan 2010 to Jun 2011, were retrospectively analyzed. Patients were divided into slow blood flow group (n=51, TIMI flow ≤ grade 2) and normal flow group (n=437, TIMI flow= grade 3). Their clinical characteristics between two groups were compared. Results: Compared with normal flow group, there were significant reductions in percentages of thrombus aspiration (75.3% vs. 60.8%) and application of platelet glycoprotein IIb/IIIa receptor antagonist (81.7% vs. 68.6%) during PCI, and significant rise in total length of implanted stents [(31.8±12.2) mm vs. (35.7±12.0) mm] in slow blood flow group, P<0.05 all. Multi-factor Logistic regression analysis indicated that percentages of thrombus aspiration during PCI and total length of stents were independent influencing factors for slow blood flow (P<0.05 both). Conclusion: Percentages of thrombus aspiration and total length of stents during PCI are independent influencing factors for slow blood flow.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To evaluate the efficacy of intravenous recombinant human brain natriuretic peptide in acute anterior myocardial infarction complicated with heart failure.Methods Two hundred patients suffered from acute anterior myocardial infarction complicated with heart failure were randomly divided into two groups:rhBNP group ( n =100) and control group ( n =100 ).All patients were given conventional treatment,patients in rhBNP group were given rhBNP on the basis of conventional therapy.The clinical effectiveness including the improvement of cardiac function,cardiac ultrasound data,the incidence of hospital adverse cardiac events,and six month follow-up were compared between the two groups.Results The degree of decompensation and Killip class in rhBNP group were better than those of control group after treatment ( improved dyspnea:significantly improved:36 vs 27 ; improved:49 vs 46; no improvement:11 vs 20 ; deterioration:4 vs 7 ; Ridit value:0.4618 vs 0.5382,P =0.043) ( Killip class:significantly improved:26 vs 20; improved:56 vs 45; no improvement:14 vs 25 ; deterioration:4 vs 10; Ridit value:0.4553 vs 0.5447,P =0.017 ).After treatment for one week,The LVEF improvement in rhBNP group was more remarkable than that of control group ( [ 53.0 ± 5.2 ] ％vs.[ 50.0 ±:6.2 ] ％,P =0.014).The occurrence rate of angina ( 13.0％ vs.27.0％,P =0.013 ),heart failure ( 18.0％ vs.32.0％,P =0.022) and major adverse cardiac events(MACE) ( 17.0％ vs.30.0％,P =0.030) inrhBNP group was lower than that in control group.During 6 months follow-up period,event-free survival in rhBNP group was higher than that in control group ( 69.0％ vs.55.0％,P =0.041 ).Conclusion Transvenous injection of rhBNP combined with other routine treatment can improve cardiac function in patients with myocardial infarction in acute anterior myocardial infarction.It can also decrease adverse cardiac events during hospitalization and increase event-free survival in 6 months follow-up period.

Objective To investigate the short-term clinical efficacy of levosimendan on treating patients with decompensated cardiac insufficiency.Methods One hundred and twenty patients with heart failure (NYHA Ⅲ-Ⅳ or Killip Ⅲ) were randomly divided into levosimendan group(n =60) and control group(n =60).The patients in levosimendan group were given intravenous levosimendan for 24 hours beside conventional heart failure medications.The patients in control group were given the conventional heart failure medications.The left ventricular ejection fraction (LVEF) was recorded and B-type natriuretic peptide (BNP) were measured before and after treatment.NYHA grade and mortality also were recorded.All patients were followed up for 3 months.Results The LVEF in the levosimendan group after the treatment was (35.6 ± 13.3)％,significantly higher than that in the control group ((31.4 ± 6.7) ％,F =8.952,P =0.002).The BNP in two groups after treatment were lower compared with before treatment(P ＜0.05).And it was more remarkable after treatment in levosimendan group compared with control group (441.0 (212.5,1050.0) ng/L vs.870.0 (435.0,1267.0) ng/L,P =0.014).The change of NYHA grade in levosimendan group was better than that in control group after 5 d.The recovery rate and ineffective or deterioration rate in levosimendan group were 45.0％ (27/60),26.7％ (16/30) and 43.3％ (26/60) respectively,higher than that of control group (28.3％ (17/60),20.0％ (12/60),36.7％ (22/60)) (OR =2.280,95％ CI 1.163-4.468,P =0.016).There was no significant difference in term of mortality between in hospital and 3 months follow-up in the levosimendan and the control group (20％ (12/60) vs.25％ (15/60),28.3％ (17/30) vs.41.7％ (25/60),x2 =1.543,P =0.214 and x2 =2.590,P =0.108).There was a decreasing trend regarding of readmission rate during 3 months in levosimendan group compared with that of the control group (21.7％ (13/60) vs.33.3％ (20/60),x2 =3.591,P =0.058),but mortality or readmission rate was lower than that in the control group (46.7 ％ (28/60)vs.66.7％ (40/60),x2 =4.835,P =0.028).Conclusion The short-term clinical efficacy of levosimendan on treating patients with decompensated cardiac insufficiency is remarkable better than the traditional treatment.

Objective To evaluate the improvement effect of levosimendan by vein injection on short term cardiac function of patients with decompensated heart failure.Methods One hundred and sixty patients admitted due to heart failure were randomly divided into levosimendan group and control group (80 subjects for each group).Patients in control group were given a regular therapy including diuretics,vasodilators (including the recombinant human brain natriuretic peptide),angiotensin converting enzyme inhibitor(ACEI) or angiotensin Ⅱ receptorantagonists(ARB),β blockers,spironolactone and stain.Patients in levosimendan were administered levosimendan for 24 hours plus regular therapy.The improvements of dyspnoea in 9 days and cardiac function classification in 30 days after therapy were assessed.Mortality of 1 month and 3 month in two group were calculated and compared during follow-up.Results The dyspnoea improvement rate was superior than that of control group during 9 days (OR =1.956,95％ CI:1.156-3.310,P =0.013).The improvements in the levosimendan group were better than in the control group at 1 st day (OR =2.261,95 ％ CI:1.280-3.999,P =0.005),at 3rd (OR =2.002,95 ％ CI:1.111-3.607,P =0.021) and 5th day (OR =1.846,95 ％ CI:1.009 -3.377,P =0.047).However,there was no significant difference in term of improving dyspnoea between the levosimendan group and the control group at 9th day (P =0.126).Similarly,the improvement of cardiac function classification in the levosimendan group was superior than the control group during 30 days (OR =1.933,95％ CI:1.229-3.040,P =0.004).Although no significant difference was seen regarding of improving cardiac function classification between the two groups at 30th day after treatment (P =0.115),the improvements in the levosimendan group were better than in the control group at 3rd (OR =1.986,95％ CI:1.195-3.300,P =0.008),5th (OR =2.268,95 ％ CI:1.329-3.873,P =0.003),9th (OR =2.627,95 ％ CI:1.419-4.860,P =0.002) and 14th day(OR =2.212,95％ CI:1.189-4.112,P =0.012).Moreover,there was a nonsignificant reduction in terms of mortality in levosimendan group during 1-month and 3-month follow-up compared with control group (P ＞ 0.05).Condusion Levosimendan can effectively improve the short-term cardiac function in patients with decompensated heart failure.

Hydrolytic amino acids were extracted by acid hydrolysis method, then derivatized with phenyl isothiocyanate (PITC). And the samples were analysed by HPLC on an Ultimate Prime C18 (4.6 mm x 250 mm, 5 microm) column with gradient elution of 0.1 mol x L(-1) sodium acetate buffer solution (adjusted to pH 6. 5)-acetonitrile (93:7) (A) and acetonitrile-water (8:2) (B) at a flow rate of 1.0 mL x min(-1). Column temperature was 40 degrees C and the detected wavelength was 254 nm. Amino acids derivative solution remained stable in 36 hours. The response was linear for 16 amino acids with a correlation coefficient r > 0.999 5. The average recoveries were 98.01% -101.8%. The method is reliable with good accuracy and repeatability, which is useful for the determination of amino acids in Galli Gigerii Endothelium Corneum.
