Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

BACKGROUND:Readmission to intensive care unit (ICU) after discharge to ward has been reported to be associated with increased hospital mortality and longer length of stay (LOS). The objective of this study was to investigate whether ICU readmission are preventable in critical y il cancer patients. METHODS:Data of patients who readmitted to intensive care unit (ICU) at National Cancer Center/Cancer Hospital of Chinese Academy of Medical Sciences (CAMS) and Peking Union Medical College (PUMC) between January 2013 and November 2016 were retrospectively collected and reviewed. RESULTS:A total of 39 patients were included in the final analysis, and the overall readmission rate between 2013 and 2016 was 1.32％ (39/2,961). Of 39 patients, 32 (82.1％) patients were judged as unpreventable and 7 (17.9％) patients were preventable. There were no significant differences in duration of mechanical ventilation, ICU LOS, hospital LOS, ICU mortality and in-hospital mortality between patients who were unpreventable and preventable. For 24 early readmission patients, 7 (29.2％) patients were preventable and 17 (70.8％) patients were unpreventable. Patients who were late readmission were all unpreventable. There was a trend that patients who were preventable had longer 1-year survival compared with patients who were unpreventable (100％ vs. 66.8％, log rank=1.668, P=0.196). CONCLUSION:Most readmission patients were unpreventable, and all preventable readmissions occurred in early period after discharge to ward. There were no significant differences in short term outcomes and 1-year survival in critically ill cancer patients whose readmissions were preventable or not.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

BACKGROUND:Esophagectomy is a very important method for the treatment of resectable esophageal cancer, which carries a high rate of morbidity and mortality. This study was undertaken to assess the predictive score proposed by Ferguson et al for pulmonary complications after esophagectomy for patients with cancer. METHODS:The data of patients who admitted to the intensive care unit after transthoracic esophagectomy at Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College between September 2008 and October 2010 were retrospectively reviewed. RESULTS:Two hundred and seventeen patients were analyzed and 129 (59.4％) of them had postoperative pulmonary complications. Risk scores varied from 0 to 12 in all patients. The risk scores of patients with postoperative pulmonary complications were higher than those of patients without postoperative pulmonary complications (7.27±2.50 vs. 6.82±2.67;P=0.203). There was no significant difference in the incidence of postoperative pulmonary complications as well as in the increase of risk scores (χ2=5.477,P=0.242). The area under the curve of predictive score was 0.539±0.040 (95％CI 0.461 to 0.618;P=0.324) in predicting the risk of pulmonary complications in patients after esophagectomy. CONCLUSION:In this study, the predictive power of the risk score proposed by Ferguson et al was poor in discriminating whether there were postoperative pulmonary complications after esophagectomy for cancer patients.

BACKGROUND: This study aimed to investigate the risk factors and outcome of critically ill cancer patients with postoperative acute respiratory insuffi ciency.METHODS: The data of 190 critically ill cancer patients with postoperative acute respiratory insuffi ciency were retrospectively reviewed. The data of 321 patients with no acute respiratory insuffi ciency as controls were also colected. Clinical variables of the fi rst 24 hours after admission to intensive care unit were colected, including age, sex, comorbid disease, type of surgery, admission type, presence of shock, presence of acute kidney injury, presence of acute lung injury/acute respiratory distress syndrome, acute physiologic and chronic health evaluation (APACHE II) score, sepsis-related organ failure assessment (SOFA), and PaO2/FiO2 ratio. Duration of mechanical ventilation, length of intensive care unit stay, intensive care unit death, length of hospitalization, hospital death and one-year survival were calculated.RESULTS: The incidence of acute respiratory insufficiency was 37.2% (190/321). Multivariate logistic analysis showed a history of chronic obstructive pulmonary diseases (P=0.001), surgery-related infection (P=0.004), hypo-volemic shock (P<0.001), and emergency surgery (P=0.018), were independent risk factors of postoperative acute respiratory insufficiency. Compared with the patients without acute respiratory insuffi ciency, the patients with acute respiratory insuffi ciency had a prolonged length of intensive care unit stay (P<0.001), a prolonged length of hospitalization (P=0.006), increased intensive care unit mortality (P=0.001), and hospital mortality (P<0.001). Septic shock was shown to be the only independent prognostic factor of intensive care unit death for the patients with acute respiratory insufficiency (P=0.029, RR: 8.522, 95%CI: 1.243-58.437, B=2.143, SE=0.982, Wald=4.758). Compared with the patients without acute respiratory insufficiency, those with acute respiratory insuffi ciency had a shortened one-year survival rate (78.7% vs. 97.1%,P<0.001).CONCLUSION: A history of chronic obstructive pulmonary diseases, surgery-related infection, hypovolemic shock and emergency surgery were risk factors of critically ill cancer patients with postoperative acute respiratory insuffi ciency. Septic shock was the only independent prognostic factor of intensive care unit death in patients with acute respiratory insufficiency. Compared with patients without acute respiratory insufficiency, those with acute respiratory insufficiency had adverse short-term outcome and a decreased one-year survival rate.

BACKGROUND: Consensus guidelines suggested that both dopamine and norepinephrine may be used, but specific doses are not recommended. The aim of this study is to determine the predictive role of vasopressors in patients with shock in intensive care unit.METHODS: One hundred and twenty-two patients, who had received vasopressors for 1 hour or more in intensive care unit (ICU) between October 2008 and October 2011, were included.There were 85 men and 37 women, with a median age of 65 years (55-73 years). Their clinical data were retrospectively collected and analyzed.RESULTS: The median simplified acute physiological score 3 (SAPS 3) was 50 (42-55). Multivariate analysis showed that septic shock (P=0.018, relative risk: 4.094; 95% confi dential interval: 1.274-13.156), SAPS 3 score at ICU admission (P=0.028, relative risk: 1.079; 95% confidential interval: 1.008-1.155), and norepinephrine administration (P<0.001, relative risk: 9.353; 95% confidential interval: 2.667-32.807) were independent predictors of ICU death. Receiver operating characteristic curve analysis demonstrated that administration of norepinephrine ≥0.7 μg/kg per minute resulted in a sensitivity of 75.9% and a specifi city of 90.3% for the likelihood of ICU death. In patients who received norepinephrine ≥0.7 μg/kg per minute there was more ICU death (71.4% vs. 44.8%) and in-hospital death (76.2% vs. 48.3%) than in those who received norepinephrine <0.7 μg/kg per minute. These patients had also a decreased 510-day survival rate compared with those who received norepinephrine <0.7 μg/kg per minute (19.2% vs. 64.2%).CONCLUSION: Septic shock, SAPS 3 score at ICU admission, and norepinephrine administration were independent predictors of ICU death for patients with shock. Patients who received norepinephrine ≥0.7 μg/kg per minute had an increased ICU mortality, an increased in-hospital mortality, and a decreased 510-day survival rate.

BACKGROUND: Several risk scoures have been used in predicting acute kidney injury (AKI) of patients undergoing general or specific operations such as cardiac surgery. This study aimed to evaluate the use of two AKI risk scores in patients who underwent non-cardiac surgery but required intensive care. METHODS: The clinical data of patients who had been admitted to ICU during the first 24 hours of ICU stay between September 2009 and August 2010 at the Cancer Institute, Chinese Academy of Medical Sciences & Peking Union Medical College were retrospectively collected and analyzed. AKI was diagnosed based on the acute kidney injury network (AKIN) criteria. Two AKI risk scores were calculated: Kheterpal and Abelha factors. RESULTS: The incidence of AKI was 10.3％. Patients who developed AKI had a increased ICU mortality of 10.9％ vs. 1.0％ and an in-hospital mortality of 13.0 vs. 1.5％, compared with those without AKI. There was a significant difference between the classification of Kheterpal's AKI risk scores and the occurrence of AKI (P<0.001). There was no significant difference between the number of Abelha's AKI risk scores and the occurrence of AKI (P=0.499). Receiver operating characteristic curves demonstrated an area under the curve of 0.655±0.043 (P=0.001, 95％ confidence interval: 0.571–0.739) for Kheterpal's AKI risk score and 0.507±0.044 (P=0.879, 95％ confidence interval: 0.422–0.592) for Abelha's AKI risk score. CONCLUSION: Kheterpal's AKI risk scores are more accurate than Abelha's AKI risk scores in predicting the occurrence of AKI in patients undergoing non-cardiac surgery with moderate predictive capability.

OBJECTIVETo investigate the expression of matrix metalloproteinase-2 (MMP-2) and insulin-like growth factor-1 (IGF-1) in gastric carcinoma and their clinicopathological significance.

METHODSExpressions of MMP-2 and IGF-1 were examined by using immunohistochemical SP staining and cross-compared with clinicopathological features of gastric carcinoma.

RESULTSHigh expression of MMP-2 and IGF-1 were observed in 70.4% (307/436) and 49.5% (216/436) of gastric carcinoma tissues respectively, significantly higher than those in non-tumor gastric mucosa (3.3% and 5.4%, respectively; all P < 0.05). The high expression rate of MMP-2 and IGF-1 were significantly associated with the patient age, tumor size, tumor location, Lauren classification, TNM staging, depth of tumor infiltration, presence of vessel invasion, lymph node and distant metastasis (all P < 0.05). In addition, the expression of MMP-2 was positively linked with the expression level of IGF-1 (P < 0.05). Univariate analysis showed that high expression of MMP-2, was significantly associated with poor prognosis of tumor of TNM stage I and II (all P < 0.05), high expression of IGF-1 was significantly correlated with poor prognosis of patients with TNM stage I, II and III tumor (all P < 0.05). Cox multivariate analysis indicated that the high expressions of MMP-2 and IGF-1 could be independent prognostic indices for gastric carcinoma.

CONCLUSIONSHigh expression of MMP-2 and IGF-1 proteins are significantly correlated with the invasion and metastasis of gastric carcinoma, it is helpful to simultaneously detect the expressions of MMP-2 and IGF-1 proteins in predicting prognosis of patients with gastric carcinoma.

OBJECTIVETo investigate the effect of lamivudine, interferon alpha and oxymatrine treatment for surviving hepatic failure patients with hepatitis B.

METHODS200 hepatitis B patients, including 100 subacute or acute-on-chronic hepatic failure survivals (group A), and 100 chronic (group B, n=100) hepatic failure survivals, were enrolled in this study. Patients in group A received interferon alpha (n=35), lamivudine (n=33) , or combinational lamivudine and oxymatrine (n=32) therapy for six months; Patients in group B received lamivudine (n=49), or combinational lamivudine and oxymatrine (n=51) therapy for six months, respectively. After the treatment, all patients were followed-up for six months.

RESULTSAt the end of follow-up, all patients in group A survived, while in group B three patients (6.1%) receiving lamivudine, and four (7.8%, P>0.05) receiving combinational therapy died; more than 90% of all survivals had their HBV DNA loss. The HBeAg/anti-HBe seroconversion rate in patients of group A treated with interferon alpha (9/17, 52.9%) was higher than that in patients treated with combinational lamivudine and matrine (5/16, 31.3%, P<0.05), which was higher than that in the patients treated with lamivudine alone (1/17, 5.9%, P<0.01), and the Knodell histological activity index score in patients treated with lamivudine (7.2+/-0.8, P<0.05) was lower than that in patients treated with interferon alpha (8.2+/-1.3, P<0.05), and the best efficacy was found in receiving combinational therapy (6.9+/-0.7, P<0.01); Lamivudine or lamivudine in combination with matrine significantly inhibited the intrahepatic inflammatory activities, but had no effect on the existing fibrosis in group B patients.

CONCLUSIONLong term nucleotide analogues treatment may delay the progress of fibrosis in hepatitis B-induced hepatic failure survivals, and the administration of matrine in time may further enhance the anti-fibrotic effect of nucleotide analogues.
