Objective To compare the differences of cognitive dysfunction and hippocampal atrophy among patients with temporal lobe epilepsy (TLE) and healthy controls and probe into the relativity of cognitive dysfunction with hippocampal atrophy after temporal lobe epilepsy. Methods Forty-nine TLE cases and 20 healthy individuals were randomly selected. The WAMS-R and WAIS-R scales were adopted to assess the memory and intelligence of all the subjects. Hippocampal volumes were measured by semiautomatic measurement on the head magnetic resonance imaging (MRI). The degree of hippocampal atrophy (DHA) and asymmetry index (AsI) were caculated by adjusting hippocampal volumes and ratio of difference of two lateral hippocampal volumes. Results Compared with the healthy controls, not only did the TLE patients exhibit more memory deficits (83.2±21.0,t=-3.365 ,P=0.001 ), but also more fullscale intelligence (91.0±12.3, t=- 4.291, P=0.000). The bilateral hippocampi of all TLE patients significantly decreased in volume ( P=0.000 ) and increased in AsI ( t=3.975, P=0.000 ). The MQ of TLE patients was significantly negatively related to the duration of the illness ( r=-0.339, P=0.017 ). The bilateral DHA and the hippocampal AsI were negatively related to Z scores (left: r=-0.297, P= 0.038, right: r=-0.305, P=0.033, AsI: r=-0.441, P=0.002), repectively. Conclusions The more the DHA and asymmetry of bilateral hippocampi, the worse the cognitive dysfunction. The quantitative measurements of hippocampal volume could be used as a clinically effective factor for evaluating the decrease of the intelligence of TLE patients.

Digitalization of ancient medical documents has become an important platform for the development and protection of medical literature and digitalization of ancient medical documents based on ancient medical documents themselves will lead to a series of intellectual property rights. After the relationship between ancient medical docu-ments and protection of intellectual property rights was analyzed, the major intellectual property rights involved in current digitalization of ancient medical documents were pointed out with their solutions elaborated from the reasona-bleness, rationality, legality and normality.

BACKGROUND:Metabolic characteristics of the 800 meters race is not very clear, which creates a lot of obstacles for the exercise training of 800 meters race. OBJECTIVE: To investigate the characteristics of material and energy metabolism of 800 meters race, to improve the scientific training of the 800 meters race and to verify the feasibility of nuclear magnetic resonance-based urine metabonomics in sports training monitoring. METHODS: Seven middle distance athletes were subject to an 800 meters race at ultimate intensity, and their urine metabonomics analysis was conducted in combination with the Human Metabolism Database and other databases before and after exercise. RESULTS AND CONCLUSION:OPLS-DA model showed that the metabolic samples before and after movement presented the cluster-like distribution. The change was mainly caused by the folowing metabolites, including leucine, lactic acid, creatinine, succinic acid, hypoxanthine, and adenosine. Through the analysis we could infer that the 800 meters race is a sport event mainly dependent on glycolysis for energy supply, working together with raw phosphate and aerobic oxidation for energy supply. The amino acid metabolism and methane metabolism of the athletes were more vigorous after 800 meters running, and moreover, there were certain oxidative stress during the 800 meters race. These findings indicate that nuclear magnetic resonance-based urine metabonomics takes the advantages of invasive, high sensitivity, less sample requirement, simple processing.

Objective To investigate the effects of different treatment modes on the prognosis of patients with severe trauma.Methods The general data of 396 patients with severe trauma [injurey severity scores (ISS) ≥25] in our hospital emergency for treatment from January 1,2008 to January 1,2012 was collected.The trauma patients were divided into study group and control group.In the study group,the trauma patients were cared by emergency physician of our hospital for pre-hospital treatment during transportation by ambulance since January 1,2010.In the control group,the trauma patients were served with traditional pre-hospital emergency care by the 120 and 999 before January 1,2010.The injury severity score,medical care and outcomes were recorded in trauma database and the efficiency and quality of medical care were compared between two groups.Results The emergency treatment time,length of hospital stays,ICU admission rate,prehospital mortality rate,long-term (6 months) disability rate,and complication rate in the study group were lower than those in the control group,presenting (78.23 ± 21.57) min vs.(96.45 ± 35.14) min,(23.55±12.46) dvs.(28.67±20.72) d,8.1％ (18/222)vs.65.5％ (114/174),13.3％ (34/256) vs.21.6％ (48/222),4.1％ (9/222)vs.9.2％ (16/174),8.1％ (18/222)vs.18.4％ (32/174),in which the differences were statistically significant (P ＜ 0.05).Hospital mortality in the study group was also lower than that in the control group,showing 8.1％ (18/222) vs.12.6％ (22/174),but there was no statistically significant difference (P ＜ 0.05).There was no significant difference in time from occurrence of injury to receiving treatment between the two groups.Conclusion Emergency physicians-cared mode had advantages to improve treatment success rates and reduce mortality in patients with multiple trauma compared with the current conventional emergency mode.It is a good alternative emergency mode.

Objective To observe the hemostatic efficacy and safety of argon plasma coagulation (APC) through bron?choscope after biopsy. Methods The APC was given to patients suffered from coronary heart disease combined hyperten?sion or paroxysmal auricular fibrillation and accepted bronchoscopy biopsy with much bleeding. The hemostatic effect and changes of heart rate, blood pressure and SPO2 were observed before and after treatment. Results Sixty-two patients were treated with endoscopic hemostasis by APC. The hemostasis was successful in 60 cases. The hemostasis was performed with APC successfully in 2 patients after intubation and mechanical ventilation because of the biopsy hemorrhage. Sixty-two cas?es included 42 cases of airway tumor (26 cases in lobe bronchus and 16 in segmental bronchus), 16 cases of broadening of the trachea ridge and mucosal rough, and 4 cases of granulation tissue of lobe bronchus. There were no significant differenc?es in mean arterial pressure and heart rate before and after treatment in 60 patients (P>0.05). The oxygen saturation was sig?nificantly lower after treatment than that before treatment (0.939±0.027 vs. 0.956±0.017, P<0.05). Conclusion Hemosta?sis treatment by APC through bronchoscope has the characteristics of rapid, thorough and safe, especially for patients com?bined with cardiovascular disease. It can avoid the occurrence of cardiovascular system complications caused by convention?al hemostatic treatment.

Aquaporin 1 (AQP1) is a specific protein that transports water molecules through the cell membrane. AQP1 mainly ex-presses in the choroid plexus epithelial cells of the central nervous system and participates in the formation of cerebrospinal fluid. In gli-omas, AQP1 expresses in neoplastic astrocytes and vascular endothelial cells. AQP1 expression is increased in parallel with histological grade in gliomas. AQP1 expression in gliosarcoma cell line is induced by dexamethasone, platelet-derived growth factor, sodium chlo-ride, hypoxia, D-glucose, and fructose. AQP1 mRNA expression is upregulated with increasing dosage. Through the expression of AQP1 in gliomas and the existing research on its function, we suggest that AQP1 may participate in tumor angiogenesis and tumor-relat-ed edema. AQP1 is closely associated with glioma cell migration. The function of AQP1 and its mechanism has been elucidated. Thus, this protein can be used as a new therapeutic target to inhibit the metastasis and recurrence of gliomas.

Objective:To explore the expression of aquaporin1 (AQP1) in human glioma tissues and its relationship with the clini-copathological parameters and prognosis of this tumor. This study also observed the function of AQP1 in the proliferation and invasion of LN229 glioblastoma cells. Methods:The expression of AQP1 in 135 cases of glioma was detected by immunohistochemical meth-od, and the correlation between AQP1 and pathological features of glioma was analyzed. The relationship of AQP1 with survival was al-so investigated using 103 specimens with complete clinical data. AQP1 was successfully transfected into LN229 cells with lentiviral vector, and the expression of AQP1 protein was tested by Western blot. Cell proliferation was detected by using methyl thiazolyl tetrazo-lium assay, whereas cell invasion was determined by Transwell assay. Results:The expression of AQP1 was positively correlated with pathological grading. High AQP1 expression was associated with poor prognosis (P<0.05). Moreover, the overexpression of AQP1 can significantly increase the proliferation and invasion of LN229 cells (P<0.05). Conclusion:AQP1 is closely associated with the progres-sion of glioma. Upregulation of the AQP1 expression promoted the proliferation and metastasis of glioma cells. These findings indicat-ed that AQP1 can function as a therapeutic target for glioma in future research.
