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 evaluate the pharmacokinetics of palonosetron hydrochloride in healthy volunteers. Methods: Thir-ty-one healthy volunteers were grouped into three palonosetron hydrochloride dosage regimens of 0.125, 0.25, and 0.5 mg. The plasma concentrations of palonosetron were determined by ultra high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). DAS 2.1 software was applied to assess the plasma concentration-time data. Results:After intravenous injection of 0.125, 0.25, and 0.5 mg palonosetron to the subjects, the AUC0-168h values of palonosetron were (7.5±2.5), (15.2±4.0), and (34.8±9.7) μg· h·mL-1. The t1/2 values were (27.2±9.5), ( 27.2±6.5), and (31.4±5.6) h. Palonosetron exposure increased proportionally with the dose range of 0.125 mg to 0.5 mg. The correlation coefficient was 0.998. No grade 3 or grade 4 toxicity was observed during the study. Con-clusion:A rapid, sensitive, and selective UPLC-MS/MS method for palonosetron quantification in human plasma was developed and validated. All the participants indicated high tolerance throughout the study. Our data showed that palonosetron exhibits linear pharma-cokinetics over the the dose range of 0.125 mg to 0.5 mg.

Objective To investigate the effects of ultrasound irradiating hydroxycamptothecin (HCPT)-loaded microbubbles on apoptosis in human hepatoma SMMC-7721 cells, and to clarify its probable mechanism. Methods The SMMC-7721 cells were randomly divided into six groups as follows: control group, blank liposome microbubbles plus ultrasound, HCPT-loaded microbubbles, HCPT, HCPT plus ultrasound,and HCPT-loaded microbubbles plus ultrasound. Apoptosis was ascertained by Annexin V-Fire/ PI and TUNEL methods. The expression of Bcl-2 and Bax protein was detected by immunocytochemistry staining technique. Results In the group of HCPT-loaded microbubbles plus ultrasound,the apoptosis rate at early term was found to reach (12.18 ± 1.38)% by Annexin V-Fitc/PI assay, brown-colored positive apoptotic cells were observed and the apoptosis rate at advanced term was found to reach (34.25 ± 1.83)% with TUNEL method. The expression of Bcl-2 was found to decrease,the expression of Bax increase,and the ratio of Bcl-2/bax significantly decrease by immunocytochemistry staining technique in the same group. Differences with other groups were significant. Conclusions The method of ultrasound irradiating HCPT-loaded microbubbles can notability induce human hepatoma SMMC-7721 cells apoptosis. The decrease in the ratio of Bcl-2 to Bax might be responsible for cells apoptosis.

Objective To evaluate the effect of exercise on the relationship between body mass index (BMI) and health-related quality of life (HRQOL).Methods A total of 1 114 participants were recruited from the Physical Examination Center of two hospitals.SF-36 was used to measure HRQOL,and the classification of sports level was done according to the subjective evaluation of participants.Results The total score of HRQOL,physical component summary and mental component summary were 76.26± 16.10,75.97 ± 16.67 and 76.55± 18.33 respectively.The results of correlation analysis were as following:the positive correlation between BMI and general health (r=0.109),vitality (r=0.116),social functioning (r=0.092),role emotional (r=0.122),mental health (r =0.145) were significant (P＜ 0.01).The negative correlation between BMI and PF(r=-0.07,P=0.019)was significant.The mediation effects of exercise in was relationship between BMI and general health,vitality,mental health were significant,and the mediating effect were 5.84％,9.14％ and 6.58％.Conclusion This study demonstrates that mediation effects of the exercise are significant in some dimensions of HRQOL,but the direct influence of BMI on the HRQOL plays a leading role.And BMI is a protective factor under certain conditions.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

Objective:To investigate the relationship between the gene polymorphism cluster of differentiation 14 (CD14)-159C/T (rs2569190),and interleukin-8 (IL-8)-251A/ T (rs4073)and the susceptibility of necrotizing enterocolitis (NEC),to clarify the influencing factors of susceptibility of NEC and to provide genetics theory basis for the research on the pathogenesis of NEC. Methods:Total 28 newborns with NEC and 41 newborns without NEC were selected.The amplification of peripheral blood DNA was conducted by PCR.The genotypic and allelic frequencies of CD14-159C/T and IL-8-251A/T of the patients were detected by Sanger DNA sequencing method. The relationship between them and the susceptibility of NEC was studied.Results:The distribution of genotypic frequencies of CD14-159C/T and IL-8-251A/T was consistent with Hardy-Weinberg equilibrium (P >0.05).There were no significant differences of the allelic and genotypic frequencies of CD14-159C/T,or genotypic frequencies of IL-8-251A/T between two groups (P >0.05).While in NEC group,the T allelic frequency of IL-8-251A/T site was higher than that in control group (χ2 = 4.184, P = 0.041, OR = 2.14, 95% CI: 1.03 - 4.46 ). Conclusion:The polymorphism of CD14-159C/T is irrelevant to the pathogeny of NEC,but T allelic frequency of IL-8-251A/T site might be related to the susceptibility of NEC.So T allele in IL-8-251A/T may be one of the danger factors of NEC.
