Objective To observe the effects of methionine enkephalin (M-Enk) on migration of macrophages from mice with impaired liver and its immunomodulatory mechanisms. MethodsLiver of mice was impaired by feeding CCl4 and macrophage migration inhibitory factor (MMIF) was produced by Con A-stimulated spleen lympho- cytes. Inhibition of macrophage migration was measured in reaction system by adding M-Enk. Results Migration of macrophages in both liver-impaired and control group were suppressed by MMIF, but the suppression might be re- versed by adding 1 μmol/L M-Enk (P<0. 05). M-Enk could significantly inhibit in vitro both of the combination of MMIF with macrophages and production of MMIF from lymphocytes (P<0. 01). Macrophages from liver-imparied group showed a higher sensitivity compared to the control group (P<0. 05). ConclusionThe study suggests that opi- oid peptieds play an important role in the modulation of the immune response under stress as liver impairment.

Objective To explore the application effect and nursing methods of pulse indicator continuous cardiac output (PICCO) monitoring technology in large area burn patients. Methods A total of 82 cases of large area burn patients in the hospital from January 2014 to June 2017 were chosen and divided into experimental group (41 cases) and control group (41 cases) by random digits table method. Two groups of patients were treated with the same method, the control group using routine monitoring method to guide liquid resuscitation, the experimental group based on the use of PICCO monitoring technology to guide fluid resuscitation. Hemodynamic indexes, fluid resuscitation time, ICU days, complication rate and mortality rate of the two groups were compared and analyzed. Results After fluid resuscitation, the acute physiology and chronic health system II (APACHE II) score, heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP) of the observation group were (18.4 ± 4.2) marks, (98.7±8.5) once/min, (88.5±9.6) mmHg (1 mmHg=0.133 kPa), (10.3±2.5) mmHg.The APACHE II score, HR, MAP and CVP of the control group were (22.7±5.4) marks, (112.5±9.6) once/min, (81.2±10.5) mmHg, (7.9±2.2) mmHg. There were significant differences between the two groups (t=3.285-6.891, all P <0.05). The cardiac index (CI),cardiac output(CO), global end-diastolic volume index (GEDVI), intrathoracic blood volume index(ITBVI), extravascular pulmonary water index(EVLWI) of the observation group after fluid resuscitation were (4.21±0.46) L·min-1·m-2, (4.87±0.52) L/min, (734.51±95.83) ml/m2, (725.91 ± 88.42) ml/m2, (6.26 ± 1.21) ml/kg, respectively. The difference was statistically significant compared to those before fluid resuscitation (t=10.454-21.143, all P <0.05).Resuscitation time and ICU days in the observation group were (3.1±1.2), (31.4±5.8) d. Resuscitation time and ICU days in the control group were (3.9 ± 1.5), (37.8 ± 6.5) d. There were significant differences between the two groups (t=2.667, 4.704, P<0.05). Conclusions PICCO monitoring plays an important role in the early fluid resuscitation in the treatment of large area burn patients, and strengthening the nursing work is beneficial to the targeted treatment and rehabilitation of the patients.
