Objective To investigate the event-based prospective memory (EBPM) and time-based prospective memory (TBPM) in temporal lobe epilepsy patients,and test the hypothcsis that temporal lobe is involved in the prospective memory network. Methods Sixty-two patients with temporal lobe epilepsy (TLE) and 30 age- and education level-matched healthy adults were examed with the neuropsychological battery of tests including EBPM and TRPM tasks. Results In comparison with the controls,the TLE patients were impaired on MMSE,DS and VFT.Compared with the healthy adults ( EBPM:6.83± 1.34,TBPM:5.00 ± 1.70),the patients with temporal lobe epilepsy had a significant loss in EBPM (3.95 ±2.77,t =6.72,P <0.01 ) and TBPM (3.08 ±2.42,t =4.39,P <0.01).There was no difference in the performance of EBPM (3.82 ± 2.70,4.10 ± 2.90 ; t =- 0.40,P > 0.05 ) and TBPM (2.55 ± 2.20,3.69± 2.55; t =-1.90,P >0.05 ) between the patients with taking antiepileptic drugs and those without antiepileptic drugs. Conclusions These results suggest that patients with temporal lobe epilepsy may experience general difficulties with prospective memory.It is possible that temporal lobe is involved in the prospective memory network.The passages of TBPM need more self-initiated processes.

Objective To identify the histopathological characteristics of multiple organ dysfunction syndrome (MODS) with V. vulnificus in mice. Methods Sixteen healthy KM mice (6~8 week old ) divided randomly into two groups, study group ( n =12) and control group ( n =4) The animal model of MODS was established by received either an intraperitioneal, intramuscular subcuneous inoculum of 4.34?10 6 cfu/0.2 ml of V.vulnificus or intraperitioneal injection of a sterile physiological salt solution (control group). Pathological changes of the man organs were individually obsenved in under election microscope (EM). Results Mortality rates exced 100%, 12/12) in study group after inoculums of mice within 4~8 h, while in 0% (0/0) in the control . The detection rate of V. vulnificus were in 100%(12/12) from blood, hearts, lungs, livers, intramuscularly, subcutaneous in the study group, while in 0% (0/4) after sterile saline intraperitioneal injection. The man histopathological changes were :degeneration and necrosis of the parenchyma cells in the different organs;interstitial swelling, mitochondriondrial injure of multiple organs.These changes were especially obvious in the lungs and myocardeum. Conclusions Above pathological changes suggested that results of MODS caused by V. vulnificus septicemia,the multiple organs failure as an important feature of the fatality of V. vulnificus infections,and my be helpful for researchers investigating of V.vulnificus.
