Objective To report the early mortality and associated risk factors after damage control operation (DCO) in patients with severe abdominal trauma.Methods A total of 146 patients hospitalized from January to March in 2015 were retrospectively analyzed.Early death was defined as death occurring within 72 h of first surgery and before the definitive surgery.Based on the death definition, the subjects were divided into death group and survival group.The two groups were compared for gender, age, injury time, injury classification, vital signs, need for cardiopulmonary resuscitation, Glasgow coma score (GCS), injury severity score (ISS), hemoglobin, platelets, prothrombin time (PT), activated partial thromboplastin time (APTT), blood pH, base excess, operative time, and postoperative acute physiology and chronic health evaluation score Ⅱ (APACHE Ⅱ).Logistic regression analysis was applied to examine the predicators of early postoperative mortality.Results There were 118 patients (80.8%) in survival group and 28 patients (19.2%) in death group.Survival and death groups differed significantly with regard to the percent of elderly (6.8% vs.21.4%), percent of patients with multiple injury (62.7% vs.85.7%), body temperature [(36.1 ± 0.4) vs.(35.2 ± 0.8) ℃], percent of patients with greater ISS (31.4% vs.64.3%), PT [(12.1±1.5) vs.(13.9±1.2)s], bloodpH (7.25±0.04vs.7.08±0.11), base excess [(-8.9±2.8) vs.(-10.6±3.3)mmol/L], postoperative APACHE Ⅱ[(12.8 ± 1.8) vs.(17.5 ± 2.0) points] (P < 0.05).Logistic regression analysis identified the age (OR=1.512, 95% CI 1.112-4.157,P<0.05), ISS (OR =1.313,95% CI 1.134-5.442, P < 0.05), APACHE Ⅱ (OR =1.361,95 % CI 1.182-5.222, P < 0.05) as the independent risk factors for early mortality.Conclusion The patients underwent DCO for severe abdominal trauma has a high early mortality, which is closely associated with the age, injury severity and postoperative medical status.

Objective To investigate whether mixed venous-arterial carbon dioxide difference (Pv-aCO2) combined with passive leg raising (PLR) could better guide volume management for patients post off-pump coronary artery bypass grafting (OPCABG).Methods Eighty patients experienced OPCABG, and admitted to Tianjin Chest Hospital from June 1st to October 1st in 2016 were enrolled. They were randomly divided into two groups: observation group given Pv-aCO2 combined with PLR directed therapy and control group given central venous pressure (CVP) directed therapy, 40 cases in each group. The difference in body temperature (T), heart rate (HR), mean arterial pressure (MAP), CVP, oxygenation index (PaO2/FiO2), mixed venous oxygen saturation (SvO2), Pv-aCO2, blood lactate (Lac), fluid intake, scores of the vasoactive agents at 6 hours post-operation, sequential organ failure assessment (SOFA) of 24 hours, mechanical ventilation time, the length of intensive care unit (ICU) stay, and hospitalization time were compared. The correlation between Pv-aCO2 and cardiac index (CI), Pv-aCO2 and Lac were analyzed by Spearman analysis in observation group.Results The T, HR, MAP, CVP, PaO2/FiO2, SvO2 and Lac at 6 hours post-operation were higher than those at admission in two groups, and Pv-aCO2 were significantly decreased. The SvO2 and fluid intake in observation group were higher than those in control group [SvO2: 0.671±0.068 vs. 0.634±0.052, fluid intake (mL): 454±151 vs. 304±106, bothP < 0.05], Pv-aCO2, Lac and scores of the vasoactive agents were lower than those in control group [Pv-aCO2 (mmHg, 1 mmHg = 0.133 kPa): 6.1±1.8 vs. 7.0±1.8, Lac (mmol/L): 1.7±0.5 vs. 2.8±0.6, scores of the vasoactive agents: 3.18±1.01 vs. 4.48±1.50, allP < 0.05], mechanical ventilation time and the length of ICU stay were less than those in the control group (hours: 16.52±6.41 vs. 21.96±9.00, 45.51±9.36 vs. 51.76±13.66, bothP< 0.05). There was no significant difference in SOFA, hospitalization time between the two groups. There was negative correlation with Pv-aCO2 and CI (r = -0.752,P < 0.01), and no correlation with Pv-aCO2 and Lac (r = -0.154,P = 0.171).Conclusion Pv-aCO2 combined with PLR can better guide volume management in the patients post OPCABG, reduce the usage of vasoactive agents and decrease the mechanical ventilation time and the length of ICU stay.

Objective To prepare the monoclonal antibody against human perforin(HP). Methods Recombinant eukaryotic expression plasmid pCDM8-HP was extracted and purified, and the BALB/C mice were immunized with the plasmid. The hybridomas producing anti-HP McAbs were established by using hybridoma technique, then the specificity of the McAbs was identified by using immunocytochemical technique and Western blot. Results Three hybridoma cell lines secreting McAbs against human perforin were established, and the three McAbs showed positive only with LAK cells containing human perforin protein, and showed negative with inactive human peripheral blood lymphocytes (PBLs). The subclasses of the three McAbs were determined as lgG2bK. Western blot results showed that the three McAbs recognized a specific band of LAK cell lysateds with molecular weight of 70.0Kd. Conclusion The three hybridoma cell lines secreting McAbs against human perforin were established and the secreted McAbs were specific.

Objective To explore the activity and its possible neural mechanism of brain default mode network by using resting state functional magnetic resonance imaging (fMRI) in patients with mild cognitive impairment (MCI). Methods The 20 amnestic MCI patients and 25 healthy controls were included in this study, and all subjects underwent mini-mental state examination (MMSE), auditory verbal learning test (AVLT) and fMRI. The data were analyzed by amplitude of low frequency fluctuation (ALFF), and the enhanced and weakened regions of ALFF were observed and compared in both MCI patients and healthy controls. Results MMSE and AVLT tests showed that the memory function was seriously impaired in MCI patients compared with healthy controls, which is based on the short and long delayed episodic memory impairment (2.4±1.7 vs. 6.6±1.4, t=3.70, P<0.01; 2.1±1.6 vs. 6.7±1.5, t=4.16, P<0.01). The resting state fMRI showed that MCI patients had significant decreases of ALFF in hippocampal formation, parahippocampal cortex and lateral temporal cortex as compared with health controls (t=2.58, 2.43 and 1.75, all P<0.01), which were closely relevant to the episodic memory. And they had significant increases in temporal-parietal joint and inferior parietal lobule (t=3.14 and 2.77, both P<0.01). Conclusions MCI patients show significant decreased active intensity of some DMN nodes that is related to episodic memory in resting state. Increased active intensity in MCI patients would be some type of compensation.

This paper aimed to review the recent literature on the TCM treatment for stroke sequelae. The content summarized and discussed the definition of stroke sequelae, herbalmedicine, TCM patents, acupuncture and so on. Sequelae of stroke’s pathogenesis was mainly caused by deficiency generating stasis, so the treatment principles were to tonifying Qi and blood and promote circulation and remove stasis with the common prescriptions, such asBuyang-Huanwudecoction,Xuefu-Zhuyu decoction andDihuang-Yinzi. Meanwhile, Chinese medicine patents and acupuncture treatment canimprove the brain function and ADL.

Objective To express human B7.2 extracellular domain with prokaryote expression system and to evaluate its biological activity in vitro. Methods PCR was used to amplify the extracellular region of human B7. 2which contained both the IgV and IgC domains. The recombinant PGEX-4T-3/hB7. 2 (IgV+C) was obtained by cloning the PCR product into a prokaryote expression plasmid PGEX-4T-3 and was transformed into the host strain of DH5-α. The fusion protein consisted of GST and hB7.2(IgV+C) was identified by SDS-PAGE and Western blotting.T cell activation was observed by exposing purified T lymphocytes to the fusion protein and [3H]-TdR incorporation with the presence of the first signal imitated by anti-CD3 antibody. Results The fusion protein GST-hB7.2 (IgV+C) was produced and detected in inclusive body form from engineered bacterial cells. With the first signal existed,T lymphocytes proliferated when it was co-stimulated by the fusion protein. Conclusion These results indicated that the functional human B7.2(IgV+C) fusion protein can be produced in bacterial cells and the fusion protein displays the co-stimulatory activity in T lymphocytes activation.
