The syndrome of malignant migrating partial seizures in infancy (MMPSI) is one of the most severe epileptic encephalopathies of infancy onset.It has been firstly reported by Coppola in 1995.There have been approximately 80 cases reported worldwide by now,but there is no case reported in our country.The etiology for MMPSI is still unknown,the diagnosis is difficult,and conventional antiepileptic drugs have little efficacy.This paper reviews the possible causes,clinical characteristics,diagnosis and treatment of MMPSI.

AIM: To establish a simple and repeatable orthotopic animal model of the A549 cell line.METHODS: A549 cells in matrigel were inoculated into left lung or right flank of nude mouse. The growth pattern of A549 tumors and the chemotherapeutic efficacy of carboplatinum were studied. RESULTS: Tumors generated and dispersed widespreadly to contralateral lung. Tumors in lung were less susceptible to carboplatinum than those growing in flank. CONCLUSION: A simple and repeatable orthotopic animal model of the A549 cell line was presented, this allows researchers to evaluate novel compounds and new drugs for treatment of human lung cancer.KEY WORDS A549 cell line; orthotopic model; nude mice

Ghrelin is a small active peptide secreted by gastric fundus cell. As an endogenous ligand of growth hormone receptor,it helps to promote growth hormone secretion,increase food intake and participate in energy metabolism. Recently,studies have indicated that Ghrelin,together with other peripheral signals,participate in the regulation of glucose and lipid metabolism. Insulin resistance (IR) is an important pathophysiological basis of the development of type 2 diabetes mellitus (T2DM),while obesity is the common risk factor of both IR and T2DM. It has been confirmed that Ghrelin has a close and complex connection with obesity and T2DM. Further study about Ghrelin may open up a new way to the diagnosis and treatment of obesity and T2DM.

Objective To investigate the effect of dexmedetomidine combined with sufentanil on postoperative analgesia and the vascular crisis in patients undergoing free flap transplantation. Methods Forty patients with ASA physical statusⅠ-Ⅱhaving underwent free flap transplantation were divided into groupⅠand groupⅡaccording to the random digits table method with 20 cases each. The drugs of patient controlled intravenous analgesia (PCIA) in groupⅠwere sufentanil 1.0μg/(kg·d)+tropisetron 5 mg/100 ml, and the drugs of PCIA in group Ⅱ were sufentanil 1.0 μg/(kg · d) +dexmedetomidine 1.0 μg/(kg · d) + tropisetron 5 mg/100 ml. The PCIA pump was set in 2 groups as follows: continuous perfusion rate 2 ml/h, single bolus 2 ml, lockout time 15 min. The visual analogue score (VAS), Ramsay sedation score, press number of PCIA pump within 48 h after operation, satisfaction score after operation, untoward reaction and vascular crisis were recorded. Results The VAS at 6, 12, 24 and 48 h after operation in group Ⅱ were significantly lower than those in group Ⅰ: (2.18 ± 0.41) scores vs. (3.00 ± 0.63) scores, (2.64 ± 0.51) scores vs. (3.82 ± 0.60) scores, (2.55 ± 0.52) scores vs. (3.36 ± 0.51) scores and (2.27 ± 0.47) scores vs. (3.09 ± 0.70) scores, the Ramsay sedation scores were significantly higher than those in group Ⅰ: (2.42 ± 0.51) scores vs. (2.00 ± 0.58) scores, (2.74 ± 0.45) scores vs. (2.11 ± 0.57) scores, (2.58 ± 0.51) scores vs. (2.05 ± 0.52) scores and (2.53 ± 0.51) scores vs. (2.00 ± 0.47) scores, and there were statistical differences (P<0.05). The press number of PCIA pump within 48 h after operation in groupⅡwas significantly lower than that in groupⅠ:(3.75 ± 1.45) times vs. (8.25 ± 2.61) times, the satisfaction score after operation was significantly higher than that in groupⅠ:(2.47 ± 0.51) scores vs. (1.60 ± 0.50) scores, and there were statistical differences (P<0.05). There were no statistical differences in the incidences of untoward reaction and vascular crisis (P>0.05). Conclusions Dexmedetomidine can relieve anxiety and nervousness, reduce postoperative consumption of sufentanil, and decrease the incidence of nausea and vomiting. In addition, dexmedetomidine does not affect the incidence of vascular crisis.
