Objective To observe the changes of blood sugar following use of recombinant human growth hormone (rhGH) in patients with severe burn. Methods A total of 140 patients with severe burn but with no history of diabetes were randomly and equally divided into Group A ( 18-44 years old) and Group B ( ≥45 years old) according to WHO criteria. Then, two groups were randomly divided Group B0 (treated with normal saline), 35 patients per group. Change of blood sugar and amount of insuline for control of blood sugar were observed and analyzed. Results Of 140 patients in four groups,128 patients accomplished the test, with no statistical difference upon general conditions between groups (P ＞0.05 ). Within four weeks after test, the amount of insuline used for control of blood sugar was (2908.0 ± 153.5) IU and (724.1 ± 31.1 ) IU respectively in Groups A1 and A0, (3725.9 ± 88.4) IU and (801.8 ±22.2) IU respectively in Groups B1 and BO. The results showed that the patients needing insulin to control blood sugar in Group B were more than that in Group A ( P ＜ 0.01 ). The time for blood sugar recovering to normal range in patients with high blood sugar with no use of rhGH in Group A1 and Group B1 was (5.21 ±0.64) d and (5.03 ± 1.01) d respectively (P＞0.05). Conclusions The blood sugar of patients with severe burn will rise after use of rhGH. The age of the patients is positively correlated with changes of blood sugar. Standard use of rhGH does not induce diabetes.

Objective To compare the air permeability,water absorption and water locking properties of two different foam dressings,thus to provide theoretical and experimental evidence to alternative optimization for acute and chronic wound.Methods Five Mepilex foam dressings(group 1) and PermaFoam Comfort dressings(group 2) each was selected.Simulated wound exudation was made by NaCl and CaCl·H2O.The water-absorbing rate of dressings at post immersion 24 h (PIH),the water-absorbing speed of dressings at post immersion 1,5,10,20 min,the diffusion diameter of exudation dripped on the surface of dressings for 5 min,the beaker filled with exudation was sealed tightly by dressing for 24 h,and the weight was gotten before and after 24 h.Statistical analysis was performed.Results (1) The water-absorbing rate:the group 1(616±19)% was significantly higher than (313±13)% of the group 2 (t=29.137,P<0.01);(2) The water-absorbing speed:the group 1 (119.68±2.59)g·s-1·m-2,(24.39±0.62)g·s-1·m-2,(12.33±0.29)g·s-1·m-2,(12.33±0.29)g·s-1·m-2 were significantly higher than those of the group 2[(65.85±4.37)g·s-1·m-2,(13.82±1.03)g·s-1·m-2,(7.16±0.41)g·s-1·m-2,(3.66±0.12)g·s-1·m-2,t=23.704,t=19.708,22.947,31.764,all P<0.01];(3) The water holding capacity:the group 1 (5.66±0.15)cm was significantly higher than (2.2±0.12)cm of the group 2,(t=39.089,P<0.01);(4) The air permeability:there was no statistically significant difference between the two groups(t=0.189,P>0.05).Conclusion The Mepilex foam dressing is more suitable for the early stage of acute wound with large exudation in short time,while the PermaFoam Comfort dressings is better for chronic wound or the later period of acute with less exudation in a relative slow seepage velocity.

Autonomic nervous system activation can result in significant changes of atrial electrophysiology and facilitate induction of atrial fibrillation. By recording influence of different concentrations of acetylcholine (ACh) on atrial fibers (AF), we investigated the role of the increased vagal tone in electrical remodeling in atrial fibrillation. Parameters of action potentials and force contraction (Fc) in atrial fibers were recorded by using standard intracellular microelectrode technique and force transducer. It was found that: (1) ACh at 0.1 μmol/L had no significant influence on spontaneous action potentials (SAPs) and Fc (n=6, P>0.05); ACh at both 1.0 and 10.0 μmol/L shortened action potential duration (APD) and Fc of human AF from right atrium (n=6, P<0.05); there was no significant difference in shortening APD between 10.0 and 1.0 μmol/L of ACh; (2) ACh at 0.1 μmol/L had no significant desensitization (n=6, P>0.05), but ACh at 1.0 and 10.0 μmol/L had desensitization (n=6, P<0.05) to SAPs and Fc. The desensitization of ACh on APD in AF was concentration- and time-dependent. It was shown that APD was longer than the control along with extending time of continuous Tyrode's solution perfusion after desensitization. It is concluded that ACh changes the electrophysiological characteristics of human AF, indicating that increased vagal tone plays a role in the development of a vulnerable substrate for atrial electrical remodeling in atrial fibrillation.

Objective To investigate the clinical value of indwelling hepatic arterial catheter in splitting fullfilling of lipiodol treatment for giant primary hepatic carcinomas. Methods Sixteen patients with giant primary hepatic carcinomas under DSA guidance,splitting lipiodol embolizations were carried out through indwelling hepatic arterial catheter everyday until the lipiodol with fulfilling the tumors. Total forty times (average 2.5 individually)of interventional treatment were accomplished in these patients. Liver function and short-term effect after interventional therapy were observed. Results None of these 16 patients had serious liver function damage and recovered uneventfully after general protective care. PR and SD were achieved in 9 and 7 cases respectively,3 months after this interventional procedure. PD was not found. Conclusions Indwelling hepatic arterial catheter in fulfilling of lipiodol treatment for giant primary hepatic carcinomas is not only unlikely to cause serious liver function damage,but also can completely embolize the tumor quickly,therefore worthy to be recommended clinically.

Objective To evaluate the accuracy, of different threshold segmentation of 18FDG PET for target volume delineation of non-small cell lung cancer(NSCLC) and the potential influence on radiotherapy treatment planning. Methods Eight NSCLC patients who had tumor with clear margin on CT scan and the amplitude of tumor movements not more than 5 mm were enrolled. PET scans were carried out at 1 h after intravenous injection of 18FDG with CT image for attenuation revisement. Gross target volume (GTV) delineated on CT image ( GTVCT ) was used as the standard. Then, GTVs were delineated on PET image with three different threshold segmentation of 42% Imax(total) (42% of maximum voxel intensity within the tumor) ,Iback + 20% Imax-back(max) (mean background intensity + 20% of normalized background-subtracted maximum voxel intensity within the tumor) and Iback -20% Imax-back(slice) (mean background intensity + 20% of normalized background-subtracted maximum voxel intensity of each slice within the tumor) ,the corresponding GTV was named as GTV42%, GTV20%max and GTV20%slice. Both the size of GTV42%, GTV20%max, GTV20%slice and GTVCT,and the coverage over GTVCT for each GTV were compared. A three dimensional margin of 1 cm were added to GTVCT, GTV42%, GTV20%max and GTV20%slice to form corresponding PTVCT, PTV42%, PTV20%max and PTV20%slic e. Three dimensional conformal radiotherapy treatment plans were designed based on PTVCT,PTV42% , PTV20%max and PTV20%slice respectively for each patient. The prescription dose of all PTVs was 66 Gy in 33 fractions in 6.6 weeks. Both the volume accepting dose less than 95% of prescription dose within PTVCT ( VPTV ) and the lung V20 were compared among the four plans based on different PTVs. Tumor control probability(TCP) as well as lung normal tissue complication probability (NTCP) were also compared. Resuits Eight patients were enrolled in this study. Median deviation of volume between GTVPET and GTVCT were -54.1% , -21.5 % and 5.3 % for GTV42% , GTV20%max and GTV20%slice, respectively. Median coverage over GTVCT of GTV42% , GTV20%max and GTV20%slice was 45.9% ,78.0% and 95.3% respectively( F = 57.50,P＜0.01). Median 7.5% of VPTV was observed for radiotherapy treatment plan based on PTV42% ,which meant that it might induce median 1% decrease of TCP comparing with that of radiotherapy treatment plan based on PTVCT. Whereas,there were only 1.3% and 0.0% of VPTV for treatment plans based on PTV20%max and PTV20%slice respectively. As far as TCP was concemed, both PTV20%max group and PTV20%slice group were superior to PTV42% group,there was no significant difference among PTV20%max group, PTV20%slice group and PTVCT group. Lung V20 and lung NTCP showed no significant difference among all groups. Conclusions The threshold segmentation of Iback + 20% Imax-back(slice) , being slice specialized, might be an optimal threshold segmentation for target volume delineation of lung caner. Independent of information of target volume provided by CT scan in advance,it is recommended to use for the target volume delineation of NSCLC with atelectasis.
