Objective To apply electrical impedance tnmography that is a new evaluation ap-proach to monitor the development of retroperitoneal injury. We used retroperitoneal inject blood model in pigs to study the feasibility on monitoring retroperitoneal bleeding and to provide premise in theory and practice for clinical application. Methods Five pigs were used on the experiment. We insert a vessel into the retroperitoneal and inject blood to simulate retroperitoneal bleeding. Sixteen electrodes were atta-ched on the abdominal region circumference of pigs and used for electrical current injection and surface voltage measurement. Then the monitoring images were performed by electrical impedance tomography. Results The images of electrical impedance tomography retroperitoneal inject blood model of five pigs were clear, the minimal impedance scale was decreasing significantly as the bleeding volume increasing and the images were changed significantly too. The computerized tomography and the dissecting results confirmed the blood was limited in retroperitoneal. Conclusions The establishments of pigs retroper-itoneal inject blood model was successful. The images of electrical impedance tomography retroperitoneal inject blood model were clear with significant contrast. It's feasible to use electrical impedance tomography system to monitor the retroperitoneal bleeding. This technique may become a useful tool for monitoring ret-roperitoneal injury in intensive care patients.

Objective To explore the relation between vitamin D deficiency and susceptibility to spinal tuberculosis. Methods A total of 163 hospitalized patients with untreated spinal tuberculosis in Tianjin Haihe hospital were enrolled in this study from June 2013 to May 2016. A total of 170 individuals participated in health examination program at the same period were enrolled as the control group. The serum level of 25-hydroxyvitamin D [25(OH)D] was measured by enzyme linked immunosorbent assay. The 25(OH)D grading included serious deficiency group (<25 nmol/L), deficiency group (≥25 nmol/L and <50 nmol/L), insufficiency group (≥50 nmol/L and <75 nmol/L) and sufficiency group (≥75 nmol/L). Histopathological classification was confirmed by intraoperative findings. Results The serum level of 25(OH)D was significantly lower in patient group [23.99(20.55,29.54)nmol/L] than that of control group [42.94(35.68,51.04) nmol/L] (P<0.01), and which was also significantly lower in four seasons than that of controls (P<0.05). The serum levels of 25(OH)D were significantly higher in summer group than those of winter group in both patient and control groups (P<0.008 3). The proportion of patients with serious deficiency of 25(OH)D was significantly higher in spring and winter groups in patient group, which was significantly lower in summer group (P<0.01). There was no significant difference in patients with serious deficiency of 25(OH)D between four seasons (P<0.01). For control group, there was a higher proportion of cases with deficiency of 25(OH)D in four seasons, and there was no significant difference in the distribution of seasons (P>0.05). In patient group, there were 107 cases of caseous necrosis type, 56 cases of hyperplasia type, and the proportion of caseous necrosis type was significantly higher in the severe deficiency group (79.17%, 76/96) than that of deficiency group (46.27%, 31/67, P<0.01). Conclusion Excluding the effect of season, vitamin D deficiency is associated with susceptibility to spinal tuberculosis and histopathologic classification.

Objective To screen the altered gene expression profile of hippocampus after traumatic brain injury(TBI)in rats. Methods Rats(n=3)in experimental group underwent moderate fluid-percussion(F-P)brain injury and the hippoeampus sample in the injured hemisphere was removed and conserved in liquid nitrogen three hours later.The rats(n=5)of the control group underwent the same procedure except for injury.Mfymetrix rat genome 230 2.0 array was used to detect the gene expression profile of hippocampus in two groups and find the altered gene expression profile. Results A total of 159 genes in the experimental group changed significantly(≥2 folds)compared with the control group,of which 136 genes were up-regulated and 23 genes down-regulated. Conclusions The significant gene expression changes of hippocampus,especially a large mount of up-regulated genes,are detected after moderate TBI in rats,suggesting that the secondary injury following TBI is a procedure involving multiple factors.

Objective To set up a rat model with acute traumatic coma and identify the variation of microRNA in mesencephalon. Methods After rats were injured moderately by central fluid percussion system, tissues of the mesencephalon were removed one hour after injury. RNA of brain tissue of the mesencephalon was isolated for microRNA array by using the exiqon microarray system. The data were analyzed statistically by Genepix Pro 6.0 after hybridization results were scanned and fluorescence intensity standardized. Resets Hybridization results showed 33 microRNAs with up-regulated expressions but 38 microRNAs with down-regulated activity. Conclusion Expression of microRNA array shows marked changes in the tissues of the mesencephalon in rats with traumatic coma, as may be injury mechanism of traumatic coma and also a way of neurobiological protection of coma.

Objective To analyze the correlation between neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR) in peripheral blood and the therapeutic effect and prognosis of patients with advanced lung adenocarcinoma treated with tyrosine-kinase inhibitors.Methods Retrospective analysis was utilized to measure the clinical pathological characteristics and follow-up data of 40 cases with advanced lung adenocarcinoma definitely diagnosed by pathology.Correlation analysis was performed by Spearman test,and comparison of the sample rate was measured by the chi square test.Survival analysis was performed by Kaplan-Meier method,Log-rank test was used to compare patients survival difference among different groups.COX regression model was utilized to analyze the prognostic factors of patients with lung cancer.Results Through the ROC curve,the optimal cut-off points of NLR and PLR were calculated to be 3.74 and 205.1 respectively.In NLR<3.74 group,objective response rate(ORR),the median progression-free survival(PFS) and the median overall survival(OS) were 86.9%(20/23),9.02 months and 12.37 months respectively.In NLR ≥3.74 group,ORR,the median PFS and the median OS was ORR were 35.2%(6/17),3.15 months and 5.12 months respectively.Compared with NLR ≥ 3.74 group,NLR<3.74 group had a higher ORR(P=0.036),PFS(P=0.011) and OS(P=0.021),the difference was statistically significant.In PLR<205.1 group,ORR,the median PFS and the median OS was ORR were 85.7%(18/21),9.67 months and 14.35 months respectively.In PLR ≥ 205.1 group,ORR,the median PFS and the median OS was ORR were 42.1%(8/19),3.21 months and 9.25 months respectively.Compared with group PLR ≥ 205.1,PLR<205.1 group had a higher ORR(P=0.045) and PFS(P=0.018),the difference was statistically significant.COX multivariate analysis showed that NLR was an independent prognostic factor for PFS(RR=1.091,95%CI:1.004-1.185,P=0.039) and OS(RR=0.986,95%CI:0.932-1.148,P=0.021).PLR was an independent prognostic indicator of PFS(RR=1.100,95%CI:0.996-1.005,P=0.024).Conclusion NLR and PLR may be independent prognostic factors in patients with advanced lung adenocarcinoma.

Objective To examine the difference of neurological soft signs (NSS) among the remittent schizophrenia patients,first-degree non-psychotic relatives of schizophrenia patients and healthy controls.Methods The Cambridge Neurological Inventory (CNI) (the Chinese version) was administered to 86 remittent schizophrenia patients (patient group),86 first-degree non-psychotic relatives of schizophrenia patients (relative group) and 86 healthy controls (control group).Results Compared with relative group,NSS total-score,the subscore of motor coordination and sensory integration were significantly higher in patient group (P＜0.01).Compared with control group,NSS total-score,the subscore of motor coordination and sensory integration were significantly higher in patient group (P＜0.01).Compared with control group,NSS total-score and the subscore of motor coordination were significantly higher in relative group (P＜0.01).Conclusions The levels of NSS in remittent schizophrenia patients and their first-degree non-psychotic relatives are higher than normal control,and the patients have more NSS than their relatives.The motor coordination nay be a potential endophenotype for schizophrenia.
