Objective To investigate the relationship between bispectral index (BIS) and cerebrospinal fluid (CSF) concentrations of propofol or effect-site concentrations during target-controlled infusion (TCI) of propofol and evaluate the accuracy of the infusion system targeting at effect-site concentration.Methods Twelve healthy mongrel dogs weighing (17.04? 1.53) kg were anesthetized with intramuscular ketamine 5 mg?kg-1 followed by enflurane inhalation. A catheter was inserted into subarachnoid space and advanced to the base of skull for the collection of CSF. BIS, hemodynamics and PETCO2 were monitored continuously during the experiment. Target effect-site propofol concentration was set at 3 ?g?ml-1 and infusion was continued for 15 min. CSF was collected at 1, 3, 5, 10, 15, 20, 30, 45 and 60 min after infusion was started for determination of propofol concentration by high performance liquid chromatography with fluorescence detection. Results The equilibrium between predicted plasma and effect-site concentration was reached at 10.9 min and the target effect-site concentration was maintained at 3 ?g?ml-1 .The peak CSF concentration of propofol was (0.29? 0.14)?g?ml-1 .CSF concentrations were much lower than the effect-site concentrations at all sampling times (about 18.7% of the effect-site concentration on average) . BIS was consistent with the CSF concentrations of propofol. Both of them reached the lowest or peak values at 5 min after infusion was started, while the peak effect-site concentration was reached relatively later. BIS was found to be better correlated with CSF concentration (? = 0.9195) than with the effect-site concentration (? = 0.554) . The dogs developed hypotension as expected but no other severe adverse effect was observed. Conclusion The inconsistency of BIS with effect-site concentration during TCI of propofol may result from its pharmacokinetic parameters. Good correlation between BIS and CSF concentration indicates that CSF concentration can reflect the pharmacokinetic profileof propofol at effect-site more accurately than the plasma concentration during TCI of propofol targeting at effect-site concentration.

Objective To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. Methods Published articles from the earliest date available to July, 2016 were recalled from PubMed, OVID, Embase, Co-chrane Library, CNKI, VIP and Wanfang Database. Two reviewers selected independently the randomized controlled trials (RCTs) about rT-MS for stroke patients with unilateral spatial neglect, and extracted data independently and analyzed with RevMan 5.3 and GRADE profiler 3.6. Results Twelve trials that represented 353 participants were evaluated. For improving Line Bisection Test, Star Cancellation Test, Albert Test, rTMS groups were significantly more effective than the controls. rTMS groups with different frequencies all showed significantly effec-tive:for low frequency rTMS, SMD=-1.21, 95%CI=-2.17 to-0.25;for high frequency rTMS, SMD=-2.56, 95%CI=-3.54 to-1.58;for continuous theta burst stimulation (cTBS), SMD=-2.51, 95%CI=-3.66 to-1.36. Conclusion rTMS is effective on unilateral spatial neglec-tin in stroke patients.

Objective To assess the clinical outcome of varicose veins with incompetent great saphenous vein(GSV) treated with ultrasound guided foam sclerotherapy. Methods Forty limbs with moderate to severe symptomatic varicose veins with incompetent GSV in 38 patients were injected with foam sclerosing agent (Fibro-Vein) under ultrasound guidance. There were 36 patients with unilateral varicose veins and 2 with bilateral varicose veins. No of them suffered from deep vein incompetence or perforating vein incompetence. Second injection was performed one month after the initial injection in 7 limbs. Thirty-eight of 40 limbs were followed up with clinical examination and duplex ultrasound scan 30-47 months (mean 40 months) after the treatment. Results Among 38 limbs with follow-up mild debilitation was found in two limbs(5. 3%). There were no other symptoms or complications. Duplex ultrasound demonstrated four type of results: type I, sclerosed GSV trunk with no detectable venous flow in 32 of 38 limbs (84. 2%) ;type II,patent GSV trunk in 3 limbs (7. 9%) ,two of them had mild reflux in the GSV trunk;type III,sclerosed GSV trunk and mild reflux in the GSV tributaries, 1/38(2. 6%) ; type IV,sclerosed proximal GSV trunk,patent distal GSV communicated with a superficial vein and mild reflux in the veins, 2/38 (5. 3% ). Conclusions Clinical examination and duplex ultrasound scan demonstrated excellent results of varicose veins with incompetent GSV treated with ultrasound guided foam sclerotherapy 40 months after the treatment. Sclerotherapy is less invasive treatment option for varicose veins with incompetent GSV with satisfactory clinical and cosmetic outcome.

Objective: After establishing standard multi-modal therapy, prognosis of refractory and metastatic high-grade osteosarcoma remains dismal and unchanged over the last decades. Early clinical intervention to newly detected metastatic lesions is crucial and effective for better prognosis. Arsenic trioxide (ATO) is one of the oldest remedies used in traditional oriental medicine and is recently rediscovered as an immunomodulator due to its activity against other solid tumors. This study aims to evaluate the efficiency of ATO combined with first-line chemotherapy in treating pulmonary metastatic osteosarcoma patients with long-term follow-up in our institution.Methods: Osteosarcoma patients with pulmonary metastasis were intravenously administered with ATO (5-10 mg) daily combined with first-line chemotherapy for their treatment. A total of 119 patients were finally enrolled; 65 presented metastasis, and 54 relapsed with lung metastasis. Results: Two-year and five-year overall survival (OS) rates for these patients reached 52.6% and 30.9%, respectively. Only 20 cases underwent thoracotomies (16.8%). Our five-year OS was nearly similar to that of other institutions (37% in Rizzoli, Italy). We observed that combined with bone metastasis, bilateral metastasis, and >3 pulmonary nodules, incomplete resection of pulmonary lesions deteriorated the disease and significantly influenced survival as compared with all other parameters. Conclusion:Combined with conventional chemotherapy, ATO may be effective and well-tolerated as new therapeutic option for patients with nonresectable pulmonary metastatic osteosarcoma. Lung metastasectomy should be strictly selected only for populations who benefit from this treatment.
