Objective To observe the changes of autophagy and apoptosis in the cerebral cortex in rats with brain explosive injury and received hyperbaric oxygen (HBO) treatment, and investigate the effect and significance of HBO on them. Methods Fifty-four SD rats were randomly divided into control group (n=6), explosive injury group (n=24) and explosive injury treated with HBO group (n=24).The control group was not injured and 600 mg TNT electric detonators were exploded over the brain of rats at a 12 cm distance in the explosive injury group and explosive injury treated with HBO group. HBO management was given to the explosive injury treated with HBO group 3 and 22 h after explosive injury and at the same time of the other 6 d. RT-PCR and Western blotting were used to detect the changes of Beclin-1 and caspase-3 in the cerebral cortex on the 6th and 24th h, 3rd and 7th d of injury. Results The expression levels of Beclin-1 and caspase-3 in the explosive injury group and explosive injury treated with HBO group were obviously higher than those in the control group (P＜0.05). The levels of Beclin-1and caspase-3 in the explosive injury treated with HBO group were significantly lower than those in the explosive injury group at the same time points (P＜0.05). Conclusion The decreased expressions of autophagy and apoptosis in brain cells by HBO treatment might be one of the possible mechanisms of treating craniocerebral injury.

Human Interleukin-11(hIL-11)has no Cys residue in its natural form.By site-directed mutagenesis,a Cys residue can be introduced to replace the 1st residue Gly and the rhIL-11 was chemically modified by using 20 kDa mPEG-maleimide conjugated to this site.The mPEG-hIL-11 conjugate was purified and showed a single band on SDS-PAGE with an apparent molecular weight.The biological activity of purified mPEG-hIL-11 was determined using a dependent cell line 7TD1.The remaining biological activity of PEGylated-rhIL-11 was 30% of native rhIL-11,suggesting chemical modification of rhIL-11 by PEG is a promising approach for improving the pharmacological efficacy.

OBJECTIVE: To explore the effect of ghrelin on the duodenal myoelectrical activity during the feeding state and the fasting state in rats. METHODS: One pair of bipolar silver electrodes were chronically implanted in the duodenal serosa of rats for electromyography. The myoelectrical activity was recorded when ghrelin was injected intravenously into rats during the feeding state or the fasting state. Some rats were pretreated with atropine, phentolamine, propranolol, L-arginine, and (D-Lys3)GHRP-6 respectively to explore the mechanism of ghrelin. RESULTS: Duodenal migrating myoelectrical complex (MMC) could be induced by ghrelin in the feeding state. Ghrelin could shorten the length of duodenal MMC cycle and increase the amplitude and frequency of phase III during the fasting state. The percentage of phase III in the MMC cycle did not change. These effects were inhibited by atropine and L-arginine (D-Lys3)GHRP-6, but not by propranolol and phentolamine. CONCLUSION Ghrelin seems to be closely related to the duodenal motility. The excitatory effect of ghrelin on duodenal MMC might rely on the cholinergic pathway, and have a close relationship with NO. The receptor of ghrelin can regulate its activity.

OBJECTIVETo investigate the analgesic and sedative effects of inhaling a mixture of nitrous oxide and oxygen on burn patient during and after dressing change.

METHODSA total of 240 burn patients hospitalized in the Institute of Burn Research of Changhai Hospital Affiliated to the Second Military Medical University, Department of Burns of the First People's Hospital in Zhengzhou, and Department of Burns and Plastic Surgery of General Hospital of Ningxia Medical University from October 2011 to September 2012 were enrolled in our study, and they were all in accordance with the inclusion criteria. The 240 patients were divided into control group (n = 60, treated with inhalation of oxygen during dressing change) and treatment group (n = 180, treated with inhalation of a mixture of 65% nitrous oxide and oxygen during dressing change) according to the computer-generated list of random number. The other treatments in control group and treatment group were the same. Before, during, and after dressing change, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SO2), and adverse effects were observed. The degree of pain and anxiety felt by the patients were respectively evaluated with the visual analogue scale (VAS) and Chinese version of the burn specific pain anxiety scale (C-BSPAS) at the same time points as above. Data were processed with analysis of covariance, chi-square test, analysis of variance, and rank sum test.

RESULTSThere were no significant differences between control group and treatment group in the levels of HR, SBP, DBP, and SO2 before dressing change (with F values respectively 0.76, 0.06, 1.11, 0.70, P values all above 0.05). Compared with those of control group, the levels of HR, SBP, DBP, and SO2 in treatment group were significantly ameliorated during dressing change (with F values respectively 81.78, 146.36, 226.44, 205.62, P values all below 0.01). After dressing change, the levels of DBP in the two groups were close (F = 0.31, P > 0.05), but the levels of HR, SBP, and SO2 showed statistical differences (with F values respectively 7.02, 8.69, 12.23, P < 0.05 or P < 0.01). Before dressing change, the VAS scores were approximate between control group and treatment group (Z = 0.21, P > 0.05). Compared with those in control group (9.4 ± 0.7, 1.7 ± 2.5), the VAS scores were significantly lowered in treatment group during and after dressing change (1.6 ± 1.3, 0.7 ± 1.1, with Z values respectively 11.84, 3.35, P values all below 0.01). There was no significant difference in C-BSPAS score between control group and treatment group before dressing change (Z = 0.62, P > 0.05). Compared with those in control group (75 ± 13, 73 ± 12), the C-BSPAS scores in treatment group were decreased during and after dressing change (9 ± 15, 9 ± 14, with Z values respectively 11.91, 12.28, P values all below 0.01). There were no obvious adverse effects in two groups before, during, and after dressing change.

CONCLUSIONSA mixture of nitrous oxide and oxygen seems to have obvious analgesic and sedative effects on burn patients during dressing change, and it can be widely used.
