Chemical investigation was carried out to study the alkaloids from stems of Nelumbo nucifera and their cytotoxic activities. The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytotoxic activities by MTr method. Fifteen compounds were isolated from the total alkaloids extract and identified as asimilobine (1), isococlaurine (2), N-acetylnorarmepavine (3), crykonisine (4), velucryptine (5), pycnarrhine (6), liriodenine (7), nuciferine (8), nornuciferine (9), armepavine (10), N-methylasimilobine (11), coclaurine (12), N-norarmepavine (13), N-methylcoclaurine (14) and lysicamine (15). Compounds 1-7 and 12-15 were isolated from stems of this plant for the first time, and compounds 2-6 were firstly isolated from the family Nelumbonaceae. Compounds 7-10, 13 and 14 showed significant cytotoxic activities against HL-60 carcinoma cell line with inhibitory ratios of 51.36%, 59.09%, 52.51%, 53.93%, 51.43%, and 64.31% at concentration of 1 x 10(-5) mol x L(-1), respectively.

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 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.

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.

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.
