The “vertical tongue”method was used in speech training for 12 patients with functional speech disorder of consonant /L/.Af-ter treatment,the average vocal intilligibility of the 12 patients increased from 86.3% to 98.9%(P <0.05)./L/consonant average intelligi-bility increased from 42.9% to 85.2%(P <0.05).

Objective To investigate relationship of microalbuminuria (MAU) and insulin resistance (IR) to severity of coronary lesions in patients with acute coronary syndrome (ACS), and its predictive value for short-term prognosis in then.Methods In total, 162 ACS patients admitted to the department of cardiology, Guangzhou First People's Hospital, Guangzhou, Guangdong province during January 2008 to June 2009 were selected and divided into three groups according to their urine albumin excretion rate (UAER): 54 cases in normal group with UAER less than 20 μg/min, 62 cases in microalbuminuria group with UAER of (20-200)μg/min, and 46 cases in mass-albuminuria group with UAER more than 200 μg/min.Difference in IR (by homeostasis model assessment, HOMA ) and severity of coronary lesions among the three groups was assessed.Effects of baseline MAU and IR on main adverse cardiac events within the recent six months were observed in ACS patients after percutaneous coronary intervention (PCI).Results IR increased and coronary lesions aggravated as UAER increasing in all the three groups of ACS patients (P＜0.05 or P＜0.01).MAU associated with IR, with a coefficient of correlation of 0.366 (P＜0.01).Results of multivariate logistic regression analysis showed that both MAU and IR were strong independent predictors for main adverse cardiac events in ACS patients within six months after PCI.Conclusions MAU and IR associate with severity of coronary lesions in ACS patients, suggesting certain predictive value for main adverse cardiac events in short-term after PCI.

Objective To evaluate the short term and long term clinical effect of internal iliac arterial chemotherapy (IIAC) followed by surgery for invasive bladder cancer. Methods Fifty six patients with invasive bladder cancer were preoperatively treated by IIAC with cisplatin (100 mg/m 2) and adriamycin (30 mg/m 2).All the cases received IIAC twice with 3 to 4 weeks interval.Two weeks after the second chemotherapy,the patients were examined by ultrasound and cystoscopy.Bladder preserving operation or radical cystectomy was performed according to clinical stages and grades of the bladder cancer. Results Two weeks after IIAC,down staging was observed in 42 patients (75%),and no change or increase in volume and stage were observed in 14 patients (25%).After IIAC TURBt was performed on 21 patients,partial cystectomy on 5,and radical cystectomy on 28 depending on the rumor size and clinical stages.The 1 ,2 ,3 ,5 year disease free survival rate in evaluative 40 patients was 85.0%,70.0%,57.5%,50.0%,respectively. Conclusions IIAC as a neoadjuvant chemotherapy has the possibility of down staging the cancer,which provides the chance of bladder preserving operations for invasive bladder cancer, and the possibility of radical cystectomy for high stage (T 3b ～T 4) bladder cancer.IIAC followed by surgery can effectively improve the disease free survival rate for invasive bladder cancer.

Objective To study the effects of ischemia postconditioning(IPC) in reducing ischemia-reperfusion injury(IRI) in acute limp ischemia(ALI) and investigate the mechanism.Methods 45 New Zealand rabbits were treated with the method that combined high lipid diets and femoral intima injury by balloon inflation to build up limp atherosclerotic stenosis model,then they were randomly divided into three groups( each group 15 rabbits):control group;IR group and IPC group.Serum creatine phosphate kinase(CK),malondialehyde(MDA),superoxide dismutase (SOD) in three groups were measured before occlusion and 2 hours after sustaining reperfusion.The histological changes of limp skeletal muscle of experimental rabbits were analyzed and TUNEL method was used to access apoptosis of skeletal muscle cells.Results The levels of CK,M DA in IPC group were lower than IR group [ (7.49 ± 0.84)vs (8.19 ± 1.06),P＜0.05],[ (3.67 ±0.36) vs (4.06 ±0.55),P ＜0.05] while SOD level was higher than IR group [ (420.40 ± 30.94 ) vs ( 384.73 ± 44.12),P ＜ 0.05 ] ; The injury of skeletal muscles in I PC group was lighter than IR group and the apoptosis index of skeletal muscle cells was significantly decreased compared with that in IR group[(12.27+2.11)％ vs (16.62 ± 1.44)％,P＜0.01].Conclusion Applying IPC in acute limp ischemia could alleviate IRI and protect skeletal muscles.The mechanism was associated with oxidation resistance enhancing and the effects in reducing apoptosis of skeletal muscles induced by IRI.
