Objective To discuss the risk factors for coagulopathy in acute isolated traumatic brain injury (TBI).Methods A retrospective study was performed on 191 patients with acute isolated TBI hospitalized from July 2012 to June 2015.There were 70 patients with coagulopathy (coagulopathy group) and 121 patients without coagulopathy (control group).Age,gender,injury type,midline shift on CT and injury severity (Glasgow Coma Scale,GCS) were analyzed to identify the independent risk factors for coagulopathy using the logistic regression analysis.Correlation between the independent risk factors and coagulation indices was analyzed.Results Injury severity,acute subdural hematoma,intraventricular bleeding and midline shift on CT were identified as the independent risk factors for coagulopathy(P < 0.05,OR > 1).Furthermore,injury severity and acute subdural hematoma were respectively associated with abnormalities of international normalized ratio (INR) and fibrinogen (Fg) (P <0.05 or P < 0.01),intraventricular bleeding with abnormalities of prothrombin time (PT) and platelet count (PC) (P < 0.01),and midline shift on CT with abnormalities of Fg and PC (P < 0.05).Conclusions Injury severity,acute subdural hematoma,intraventricular bleeding and midline shift on CT are independent risk factors for coagulopathy in patients with acute isolated TBI,and correlate with abnormalities of several coagulation indices.Changes in coagulation indices should be monitored accurately after TBI,and timely treatment of coagulopathy can improve the prognosis.

Objective To analyze the clinical epidemiology of primary hepatocellular carcinoma (PHC) in the Xinjiang region. Methods Clinical data of the patients with PHC were collected at First Affiliated Hospital of Xinjiang Medical University from 5 577 cases from January 2002 to December 2014, their gender, race, age, household distribution, hepatitis virus-positive rate were analyzed retrospectively. Results Among the 5 577 eases, the men/women gender ratio was 3.45∶1;the proportion of Han, Uighur, Kazakh, and other ethnic groups (Hui, Mongolian, Manchu, Xibo) was 79.67%, 9.86%, 4.55%, 3.31%and 2.61%, respectively. The Constituent ratio difference between Uighur and Han was significant (P<0.05);4 232 patients had hepatitis B surface antigen (HBsAg) detection, and 3 833 patients had HCV antibody (HCV-Ab) detection. HBsAg was positive in 2 560 cases (60.49%), HCV-Ab was positive in 490 cases (12.78%). Hepatitis B virus detection positive rate in Uygur was 35.52%, in Kazak was 40.00%, which was lower than the Han's (65.68%, P<0.05). Urban and rural population had 3589 cases (64.35%) and 1988 cases (35.65%). Conclusion An increased risk for PHC was found in hepatitis virus-positive patients, the Xinjiang Uygur and Kazak people had significantly lower prevalence of HBV infection than the Han's. Appropriate measures should be taken for clinical diagnosis, treatment and prevention of PHC.

This is a research to enhance the application of natural language understanding and ontology in the Chinese medical text semantic annotation and content analysis, and so to provide technology support for the computer-readable electronic medical records (EMR). The Chinese EMR information extraction and statistical analysis of related subjects in accordance to the user's demands were performed through building the named entity rules, the classified word list and field ontology by using GATE platform on the basis of EMR text set's construction and pre-processing. The automatic and artificial semantic annotation of EMR text set was implemented. The situation of drugs used in medicinal treatment and the distribution of patients' age and sex were obtained. The ontology-based semantic information extraction can improve the function of computer for text understanding, and the discovery of knowledge in EMR through field ontology is feasible.

Objective To explore the correlation between the glucose variability and the severity of acute isolated traumatic brain injury(TBI). Method According to the inclusion/exclusion criteria,a total of 125 cases of acute isolated TBI admitted in Department of Neurosurgery of China Medical University from July 2012 to June 2015 were included. According to Glasgow coma scale(GSC),the patients were divided into five groups including control(GCS 15),mild(GCS 13?14),moderate(GCS 9?12),severe(GCS 6?8),and extra?severe(GCS 3?5)groups. Blood glucose control(including relief of the stress and the application of insulin)were carried out immediately. The average,standard deviation,and variation co?efficient of blood glucose of all groups were recorded at admission,48 hours and 3?7 days after hospitalization. The clinical records and glycemic in?dex were compared among different groups and during different periods,so as to analyze the relationship of the variability of glucose and the duration of hyperglycemia with the severity of TBI and the effects of glycemic intensive care management. Results The results of Kruskal Wallis test and Mann?Whitney Utest showed that the average,standard deviation,and variation coefficient of glucose in the extra?severe group and the severe group were statistically higher than those in the control group(P<0.05)during the same period. Meanwhile,the average,standard deviation,and variation coefficient of glucose at admission,48 hours and 3?7 days after hospitalization were also different among each group(P<0.05). The duration of hy?perglycemia and conscious disturbance in both the extra?severe group and the severe group were longer than those in the control(P<0.05). The analyses using rank correlation indicated that glucose variability,the level and duration of hyperglycemia were positively correlated with the severity of TBI(r>1). Conclusion The glucose variability in acute isolated TBI patients could be considered as the index of the severity of TBI.

Objective:To investigate the killing effect of radiation on echinococcus in vitro culture and its effect on the mRNA expression of growth arrest and DNA damage 45 alpha (Gadd45α) gene. Methods:Echinococcus from naturally infected sheep liver was cultured in vitro and divided into 7 groups. The echinococcus was irradiated with 6 MeV at doses of 0 (control), 20, 40, 60, 80, 100, and 120 Gy, respectively. The growth of echinococcus was observed under light microscope at 1, 3, 5 and 7 d after the radiation. The expression of Gadd45α mRNA in control, 20, 40 and 60 Gy groups of echinococcus was detected by RT-PCR technique at 7 d after the radiation. Results:The disintegration and exfoliation of echinococcus were observed under light microscope at 1, 3, 5 and 7 d after the radiation, and the death rate of echinococcus was positively correlated with the radiation dosages ( r = 0.81, P < 0.05). After the radiation at 7 d, compared with the control group (100.00 ± 0.00), the mRNA expression levels of Gadd45α in echinococcus of 20, 40, and 60 Gy groups were significantly increased (279.74 ± 80.08, 759.38 ± 160.98, 1 666.68 ± 316.36, P < 0.01), and it was positively correlated with the radiation dosages ( r = 0.93, P < 0.01). Conclusion:Radiation has a certain killing effect on echinococcus cultured in vitro, and there is a certain dose-effect relationship with the radiation dosages, and Gadd45α gene may be involved in the molecular mechanism of radiation-induced killing of echinococcus in vitro.
