Objective To observe the psychological stress reactions of 238 patients injured in earthquake in our hospital and explore their interventions to such reaction. Methods A total of 238 patients wounded in earthquake were recruited. Along with the active treatment of primary physical trauma, wide range of preventative psychological interventions for crisis was carried out individually or in group. The psychological emergency measures included communication and exchange of ideas, mental health education, and psychological support and a relaxing environment to the patients. All the patients were evaluated by using depression and anxiety assessment scales before and after the intervention. Results Various psychological stress responses were found in 238 patients after injury, in which sleep disorders, memory decline, tension and fear, wabble and emotional instability ranked the top 5. Some patients' psychological status recovered after one-week's hospitalization, while most recovered after two-week's hospitalization. Three patients were transferred to other professional psychiatric hospitals for professional psychological treatment and intervention because of serious psychological obstacle. Conclusion The wounded caused by earthquake manifested various psychological stress reactions. Immediate psychological intervention can effectively help the patients to recover psychologically, promote their physical rehabilitation, and prevent posttraumatic stress disorder.

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.

OBJECTIVETo compare anatomical differences between subinguinal and ilioinguinal approaches for the treatment of acetabular fracture and investigate clinical therapeutic effect of subinguinal approach.

METHODSSeven fresh human bodies were chosen, comparative study were performed on the right and left side on the same specimen. Ilioinguinal approaches were adopted on the left and subinguinal were adopted on the right. Inner part of incision started to sun wild above pubic symphysis at 2 cm, and lateral incision ranged from iliac to anterior superior spine about 5 cm. Length and transverse diameter of the first window exposed and lliopsoas freeness were tested and compared. Fifteen acetabular fracture patients treated through subinguinal approach were compared from May 2010 to August 2012. Among all patients, including 12 males and 3 females aged from 20 to 65 years old with an average of 40.6 years old. Matta criteria were used to evaluate clinical outcomes.

RESULTSLength and transverse diameter of the first window exposed and lliopsoas freeness through subinguinal approach were better than through ilioinguinal approach (P<0.01). In 15 patients with acetabular fracture, 10 patients obtained anatomical reduction and 10 patients got satisfied reduction in accordance with Matta criteria. X-ray results of all patients were excellent.

CONCLUSIONCompared with ilioinguinal approach, subinguinal approach could enlarge visualization of the first window and simplify surgical procedure. It is an ideal approach to expose anterior and anterior-medialis wall of acetabulum and anterior hip capsule.

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To explore protective effects of curcumin on lung injury in the early hepatic ischemia/reperfsion (reperfusion for 1 and 3 hour) inrats. Methods Wistarratswererandom]y divided into the fo]]owinggroups: GroupA (shamoperation), group B (control group) and group C (cureumin applied). Contents of superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), myeloperoxidase (MPO) in lung tissues were determined to evaluate the protective effect of eurcumin on lung injury in the injury of isehemia/ reperfusion. Results Curcumin relieved edema of diaphragmatic wall and exudation of blood cell and white cell in pulmonary alveoli. Curcumin increased the contents of SOD, CAT and decreased contents of MDA, MPO in lung tissue. Conclusion By repressing the generation of oxygen free radical and infiltration of polymorphonuclear leukocyte in lung tissue, curcumin can relieve lung injury in the early hepatic ischemia/repeffusion.

Objective To observe the changes of expressions of glucose transporter 1,3 gene(GLUT1 mRNA and GLUT3 mRNA) in hippocampus after hypoxic-ischemic brain damage in newborn rats and effects of progesterone on them.Methods Forty SD rats(7-day-old) were divided randomly into 4 groups:normal group,sham operation group,hypoxic-ischemic group and progesterone group.Rats were subjected to right common carotid artery ligation and exposed to 80 mL/L oxygen and 920 mL/L nitrogen gas for 2 hours to establish hypoxic-ischemic model in hypoxic-ischemic group and progesterone group.The rats in sham operation group only received right common carotid artery ligation.Progesterone(8 mg/kg) or sesame oil(of same volume) was given intraperitonealy in progesterone group or other groups 30 minutes before operation.All rats were killed 24 hours after operations.The expressions of GLUT1 mRNA and GLUT3 mRNA in hippocampus of rats in every group were assessed by adopting RT-PCR technique.Results The expressions of GLUT1 mRNA and GLUT3 mRNA in the hypoxic-ischemic group(0.674?0.083,0.785?0.093) increased markedly compared with those in sham operated group(0.374?0.061,0.519?0.060)(Pa0.05).Conclusions Progesterone maintain the energy supply of the brain by up-regulating the expression of GLUT1 mRNA and GLUT3 mRNA and accelerating the transportation of glucose into brain,which may be one of the protective mechanisms.

OBJECTIVETo observe the effect of natural type ginsenoside Rg2 (Rg2) and its stereoisomers [20 (R)-Rg2 and 20 (S)-Rg2] at different concentrations on oxygen-glucose deprivation/ reperfusion (OGD/R) induced cortical neuronal injury model in vitro, and to explore the mechanism, and compare their differences of action.

METHODSCortical neurons after 7-day culture were randomly divided into 5 groups, i.e., the control group, the model group, the Rg2 group, 20 (R) -Rg2 group, and 20 (S) - Rg2 group. Cortical neurons in the Rg2 group, 20 (R)-Rg2 group, and 20(S)-Rg2 group were pretreated with 20, 40, and 80 μmol/L Rg2, 20 (R) -Rg2, and 20 (S) -Rg2 for 24 h to prepare OGD/R model. The cell survival rate, the activity of Caspase-3, the intracellular Ca2+ concentration, contents of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected 24 h later.

RESULTSCompared with the control group, cell survival rates and activities of SOD obviously decreased, the activity of Caspase-3, Ca2+ fluorescent optical gray value, and contents of MDA significantly increased with statistical difference (P < 0.05). Compared with the model group, cell survival rates and activities of SOD obviously increased, the activity of Caspase-3, Ca2+ fluorescent optical gray value, and contents of MDA significantly decreased in 20 μmol/L Rg2 group, 40 μmol/L 20 (R) -Rg2 group, and 80 μmol/L 20 (S) -Rg2 group (P < 0.05). Compared with 20(S)-Rg2 group, cell survival rates increased and contents of MDA significantly decreased in 20, 40, and 80 μmol/L Rg2 and 20 (R)-Rg2 groups (P < 0.05). The activity of Caspase-3 decreased and contents of SOD increased in 80 μmol/L 20 (R)-Rg2 group, and 40, 80 μmol/L Rg2 groups (P < 0.05). Ca2+ fluorescent optical gray value decreased in 40, 80 μmol/L Rg2 and 20 (R)-Rg2 groups (P < 0.05). Compared with 20 (R)-Rg2 group, Ca2+ fluorescent optical gray value decreased in 80 μmol/L Rg2 group (P < 0.05); contents of SOD increased in 40 and 80 μmol/L Rg2 groups (P < 0.05); contents of MDA decreased in 20, 40, and 80 μmol/L Rg2 groups (P < 0.05).

CONCLUSIONSRg2 and its stereoisomers could improve cell vitality of cortical neurons against OGD/R induced injury. This might be related to improving anti-apoptotic capacities and antioxidant abilities, and reducing Ca2+ inflow. Besides, the neuroprotective effect of 20 (R) -Rg2 was better than that of 20 (S) -Rg2, but inferior to that of Rg2.
