Objective To evaluate sacral nerve stimulation (SNS) in the treatment of spastic pelvic floor syndrome (SPFS).Method In this study,36 patients of spastic pelvic floor syndrome who received SNS treatment from 2011.3 to 2011.12,were reviewed in terms of clinical curative effect,changes of anal pressure and defecography.Result After a course of SNS treatment,patients were followed up for 3 months,12 cases were cured,22 cases improved and 2 cases were ineffective,the total effective rate was 94.4％.The symptoms such as endless defecate feeling,difficulty in defecation,anal pain and anal obstruction feeling improved significantly (P ＜0.01 ).After the therapy,rectal anal reflex( RAR)threshold value volume rose,anal maximum contraction pressure (AMCP),anal rest perssure (ARP) decreased (P ＜ 0.01 ).While the anal longest contraction time (ALCT)and rectal rest pressure (RRP) did not change significantly (P ＞ 0.05 ).After treatment,when patient defecate the anorectal angle (ARA) increases,the puborectal muscle spasm notch (PMSN)attenuates (P ＜ 0.01 ).Conclusions SNS is effective and minimally invasive in treating spastic pelvic floor syndrome.

ObjectiveTo evaluate the clinical application of endovascular treatment for severe Takayasu's arteritis (TA).MethodsIn this study,35 target lesions in 32 patients [28 women,mean age (30 ±8) years] with severe Takayasu's arteritis were treated with endovascular merthod.The average length of lesion was 3.1 cm( range 2.7 -5.3).The overall average degree of diameter stenosis was 90％ ± 11％ (range 70- 100)in which 15 lesions were completely occlusive.There were 10 patients whose ESR were higher than 20 mm/h( range 25 -37).Follow-up included physical examination and patency evaluated by color duplex souography/computed tomography angiography/angiography at 6 months and then annually.ResultsRecanalization was unsuccessful in 3 completely occlusive lesions,with a successful rate of 80％(12/15).There was one case in which embolization leading to acute thrombogenesis developed during interventional procedure and resulting in severe stroke.The technical successful rate ( residual stenosis ＜ 50％ ) was 88.6％ ( 31/35 ).The transient cerebral ischemia attack ( TIA ) symptoms disappeared in 31 cases.26 cases were followed up for an average of (19 ± 10) months (range 13 -40).Occipital infarction following severe in-stent restenosis developed 13 months later in one case.Symptomatic in-stent restenosis18monthslaterwasfoundin2cases. Patencyratewas88.5％( 23/26 ).ConclusionsEndovascular treatment is safe and effective for severe TA.Strict indication and accurate targeting the lesions help ensure the success of management.

Objective： To study the expression and role of IL-6, IL-6 receptor(IL-6R) and acute phase reaction factor (APRF) in PMNC of multiple myeloma(MM) patients. Methods:The bioactivity of IL-6 and the level of sIL-6R in sera of MM patients were measured using IL-6 dependent cell line 7TD1 and ELISA respectively. The APRF activity of PMNC DNA binding protein was observed by gel blocking electrophoresis (EMSA). Results:The bioactivity of IL-6 and the level of sIL-6R in MM sera were significantly higher than those of the control and the level was coordinated with that of the tumor. The results of PMNC DNA binding protein EMSA showed that PMNC of MM patients expressed APRF after stimulation of IL-6,whereas there was no activity of APRF in the normal PMNC. Conclusion:In MM,some regulation machines of IL-6 signal transduction pathways changed (eg.protein kinase), resulting in the activation of transcription of acute phase reaction element(APRE), APRF may have a role in pathogenesis of MM.

ObjectiveTo evaluate the clinical safety and efficacy of SilverHawk directional atherectomy for femoropopliteal occlusive lesions. MethodsEighteen ischemia occlusive lesions in 11 patients of the lower extremity were treated with SilverHawk directional atherectomy.The mean lesion number was 1.6 ± 1. 1 per patient. The mean lesion length was ( 3.4 ± 2. 2 ) cm. The average degree of diameter stenosis was 96％ ± 14％. 9 lesions were totally occlusive. Clinical symptoms included claudication in 4 cases ( Rutherford classes: 3) and critical limb ischemia ( Rutherford classes: 4) in 7 cases. Lesions characteristics were divided by TASC classification: TASC B in 7 cases; TASC C in 1 case (in-stent occlusion); TASC D in 3 cases.Mean ABI was 0. 5± 0.4. Patency was evaluated with color duplex sonography or CTA besides clinical examination during follow-up.ResultsNine totally occlusive lesions were recanalizated successfully via intraluminal approach. 18 lesions achieved technical success (residual stenosis ＜50％ ) leaving 15％ ±7％ mean residual stenosis in mean (8 ±3)min, predilation was needed in one lesion ( in-stent occlusion) prior to atherectomy. Clinical symptoms improved or disappeared with mean ABI 1.07 ±0. 12 and Rutherford grades: 0 (n =9) and 1 (n =2). Patency rate was 100％ with mean 0. 93 ± 0. 14 ABI and Rutherford grades remain unchanged after follow-up of mean ( 9 ± 4 ) monthes.ConclusionsSilverHawk directional atherectomy is safe and effective for the treatment of lower extremity ischemia.

In China, many surveys have shown that most people do not have a correct understanding about cold and administration of anti-cold Chinese patent medicine preparations. The author conducted a systematic summary and analysis on the actual application of anti-cold Chinese patent medicine preparations as well as the warning on safe application of anti-cold Chinese patent medicine preparations in Clinical Medication Information of China Pharmacopoeia, in the expectation of reducing the blind application of anti-cold Chinese patent medicine preparations and providing traditional Chinese medicine pharmacists new ideas in monitoring the safe application of exterior syndrome-relieving Chinese patent medicine preparations.

OBJECTIVETo study the effects and mechanism of lovastatin on cell cycle phase and proliferation of cultured human glomerular mesangial cells in vitro.

METHODSHMC proliferation was determined by 3H-Thymidine incorporation. HMC cell cycle was measured by flow cytometric analysis.

RESULTSLovastatin was found to inhibit HMC proliferation in a dose-dependent manner. Flow cytometric analysis demonstrated that lovstatin induced G1/S transition arrest. Concomitant addition of mevalonate or farnesol restored all the inhibitory effect of lovstatin on HMC.

CONCLUSIONLovastatin is a HMC proliferation inhibitor. It provides an experimental evidence for re-evaluate renal protective effect of HRI, which has already been widely used in clinical treatment.

Objective:To evaluate the mortality and risk factors for acute kidney injury (AKI) in hospitalized patients by the risk, injury, failure, loss, end stage kidney disease (RIFLE) and acute kidney injury network (AKIN).
Methods:We constructed a retrospective study of all AKI patients in the Second Xiangya Hospital of Central South University between February 2006 and January 2011. The diagnosis and classiifcation of AKI were reconifrmed and categorized by RIFLE and AKIN criteria. To compare the clinical characteristics, mortality and associated risk factors in AKI patients by the RIFLE and AKIN stage, univariate analysis and multivariate logistic regression analysis were performed. Results:The patients were diagnosed as AKI by AKIN (n=1027) or by RIFLE criteria (n=1020). There was no signiifcant difference in the hospital mortality, hospital length stay (days), or the proportion of complete recovery in each stage of AKI patients by RIFLE and AKIN (P>0.05). In the univariate analysis, age, pre-renal causes, proportion of hospital acquired AKI, mechanical ventilation, hypotension, the number of failed organs, acute tubular necrosis-index severity score (ATN-ISS), and the peak of serum potassium ion concentration were signiifcantly higher in the non-survivors than in the survivors (P<0.05). Logistic regression analysis revealed that age older than 65, hospital acquired AKI, hypotension, number of failed organs, ATN-ISS scores, and the peak of serum potassium ion concentration were independent risk factors for hospital mortality. Conclusion:Both RIFLE and AKIN criteria have similar scientiifc value in assessing hospital mortality. AKI stage is associated with the recent prognosis of AKI patients.
