Methods Eighty cases of children patients with deep second-degree burn were included in this study, who were admitted in Tianjin 4th Center Hospital from March 2015 to March 2016. The cases were divided into control group and combined treatment group, 40 cases for each group. Wherein, the control group was treated with bFGF, the combined treatment group was received compound polymyxin B ointment and bFGF. The occurrence rate of infection of burn wound surface, wound healing time and occurrence rate of scar after healing were compared between two groups. Results There were lower infection rates on day 7, 10, 15 and 20 after burn in combined treatment group than those in control group (P<0.05). The healing time was significantly shorter in combined treatment group than that in control group [(21.53±1.33) d vs. (25.76±1.50) d, t=13.345, P<0.01]. The scar occurrence was significantly lessin combined group than that of control group (U=5.077,P<0.05). Conclusion The compound polymyxin B ointment combined with bFGF show a certain effect of anti-infection, acceleration of wound surface healing and preventing the scar from generating for wound surface on deep second-degree burn in children, which having a significant clinical curative effect.

Objective To evaluate the feasibility of propofol infusion by a closed-loop system for the titration of anaesthetic in laparoscopic cholecystectomy guided by Bispectral Index ( BIS). Methods Forty patients subjected to laparoscopic cholecystectomy randomly allocated into two groups: the control group with opened-loop titratioin of propofol TCI induced at a target of 4 μg?mL-1 and aintained from 2 to 5 μg?mL-1 and the treatment group with closed-loop titration was performed using a proportional differential algorithm.For both groups,the BIS was set at 45-55.Remifentanil TCI was infused at a target of 4 ng?mL-1 and was maintained according to the situation.The change in medial arterial pressure(MAP),heart rate (HR) and BIS were recorded before anesthesia(t0 ),target BIS of 50(t1 ),at tracheal intubation(t2 ),during incision of skin (t3 ),5 min after the operation(t4 ),at t5 of gallbladder removing and at t6 of skin suturing.The dose of propofol was calculated. Results Haemodynamic data were similar between groups during the induction.But MAP was decreased significantly at t1 ,t3 ,t4 , t5 in the control compared with the treatment group (P<0.05).HR changes a lot at t5 in the control compared with the treatment (P<0.05).Total dose of propofol in the treatment group was statistically lower than that in the controls [(110.10± 8.34) vs (120.55±6.26) mg; (603.20±116.55) vs (759.50±116.37) mg,P<0.05)]. Conclusion Automated titration guided by BIS for propofol infusion is feasible without increase in haemodynamic adverse effects and is of less propofol consumption in the laparoscopic cholecystectomy.

Objective To investigate the myocardial perfusion abnormalities in patients with isolated left ventricular noncompaction (ILVNC) and analyze the correlation between MPI and MRI.Methods Nineteen patients (14 males,5 females,age range:15-76 years) with ILVNC diagnosed by cardiac MRI were recruited.All patients underwent 99Tcm-MIBI MPI.Both MPI and cardiac MRI were analyzed using a 17-segment model.The thickness ratio of the non-compacted to compacted layers of myocardium (NC/C) was calculated,and segments with NC/C＞2.3 were considered as noncompaction.The incidences of delayed enhancement (DE) and myocardial perfusion abnormalities in non-compacted segments and compacted segments were calculated.x2 test was used for categorical data.The Pearson and Spearman correlation coefficient were used to assess the relationship between the numbers of myocardial segments with myocardial perfusion abnormalities/noncompaction/DE and lgLVEF.Results Of 19 patients,myocardial perfusion abnormality was found in 16 (84.2％) patients.The incidences of perfusion abnormality were 33.6％ (36/107) in non-compacted segments and 31.9％ (69/216) in compacted segments,respectively (x2=0.09,P＞0.05).There were 31 segments with DE.The incidences of DE were 5.6％ (6/107) in non-compacted segments and 11.6％ (25/216) in compacted segments,respectively (x2 =2.94,P＞0.05).The incidence of reduced perfusion was higher in segments with DE than those in segments without DE (54.8％ (17/31) vs 30.1％ (88/292) ; x2 =7.80,P＜0.01).The lgLVEF and the numbers of myocardial segments with noncompaction/DE/myocardial perfusion abnormalities were not correlated(r=-0.35,0.15,-0.34,all P＞0.05).Conclusion Most patients with ILVNC have myocardial perfusion abnormality,which can be observed both in non-compacted and compacted myocardium.Further research is required to elucidate the role of myocardial perfusion abnormality in ILVNC.
