Objective To investigate the characteristics of cognitive function impairment in patients with epilepsy. Methods Forty-five epilepsy patients and twenty age-,gender-,and education-matched healthy controls were submitted to a wide neuropsychological battery,including Raven's standard progressive matrices,auditory verbal memory test,logical memory test,visual memory test,Stroop color words test,trail making test,verbal fluency test,Boston naming test,math and complex figure test,etc. Results The epilepsy patients performed significantly worse than the controls in the verbal delayed memory,verbal short memory,cued recall,immediated recall of logical memory test,visual spatial memory,attention,information processing speed test,word finding difficulty and logical reasoning.Conclusion There exists impairment in various cognitive domains in patients with epilepsy,and the main impaired areas are memory,executive functions and logical reasoning.

Objective To investigate the application progress of postoperative fluid administration in colorectal surgery.Methods Literatures about the advancement of fluid administration in colorectal surgery were reviewed and analyzed.Results Compared to standard fluid management,restrictive fluid administration could reduce the incidence of complications,the length of stay in hospital and improve postoperative survival rate.Colloid-crystalloid combined therapy was better than that pure crystal therapy.Conclusion Volume and type of rehydration influence postoperative recovery,which is also considered in "fast track" colorectal surgery.

Objective:to study psychosomatic factors in patients with psoriasis Method:40 inpatients with psoriasis and 38 normal control were collected Both of them received a battery of psychological tests Result:patients had higher scores in life events, type A behavior, negative coping, anxiety and depression than normal control They had also lower scores in positive coping, social support The risk factors for psoriasis included positive family history, type A behavior, and depression, while protective factors included positive coping and better social support Conclusion:psychosomatic factors have great influence on psoriasis

Objective: To investigate the relationship between psychosocial stress and some neuroendocrine-immuno indexes in patients with psoriasis Methods: The psychosocial factors were evaluated by TABPQ, SDS, SAS, TAS in 40 patients with psoriasis and 38 norm controls The levels of NPY\IL-6\IL-8\Cortisol of both of them were also measured Results: 1 The scores of TH and CH of TABPQ , the scores of TAS and depression and anxiety were higher than the controls(P

OBJECTIVETo explore the alterations of after depolarization and triggered activity in myocardiac muscle during progression of mouse aortic stenosis.

METHODSAfter the establishment of mouse aortic stenosis model, the heart was collected and intracellular potential was recorded using standard glass microelectrode. After the recording, the action potential (AP), early after depolarization (EAD), delayed after depolarization (DAD) in papillary muscles were analysed.

RESULTS(1) Compared with that of time-matched control mice, there were no changes of the action potoutial duration at 90% repolarization(APD90) in model mice at 2 and 5 weeks, whereas the APD90 was progressively prolonged at 9 and 13 weeks. (2) During the 30 minites of the experiment, spontaneous EADs and DADs were frequently present in medel mice at 9 and 13 weeks, were not in control and model mice at 2 and 5 weeks. (3) Compared with those of control group, EADs and DADs triggered by hypokalaemia or isoproterenol were increased significantly. The incidence rate of triggering EADs and DADs was progressively increased over time.

CONCLUSIONEAD, DAD and trigger activities increase gradually during the process of aortic stenosis, and it suggests that the myocardium electrical-instability is markedly increased in the insult hearts.

OBJECTIVETo find the characteristic parameters from electrocardiogram (ECG) which is most related to pathological progress, surface ECG was performed in mice at 2, 5, 9 and 13 week post surgery.

METHODSElectrocardiogram recordings: The mice were anaesthetized with tribromoethanol (250 mg/kg, i.p.). Lead II surface ECG were acquired by using the Biopac System MP150 at a rate of 5 kHz.

RESULTS(1) No arrhythmia was observed in Sham and 2-week Band mice. Spontaneous arrhythmias were observed in ECG recordings, with an incidence of 15%, 28% and 63% in 5-, 9- and 13-week Band mice, respectively. Tachyarrhythmias, such as frequent premature ventricular extrasystole, bigeminy, trigeminy, and paroxysmal tachycardia were found. (2) Analysis of ECG recordings revealed a significant prolongation of QT and QTc intervals. Compared with age-matched Sham mice, the increment in QT and QTc intervals was 20.4%, 32.7%, 49.7%, 61.0% and 27.1%, 32.1%, 43.9%, 59.1% at 2, 5, 9 and 13 week, respectively (P < 0.01). (3) The characteristic change in electrocardiogram was on the J wave. The amplitude of J wave was upward in Sham mice, and it was significantly flattened or inverted in Band mice. (4) Except that RR interval at 2 week showed a slight decrease, there was no significant change in PR interval and RR interval in Band mice.

CONCLUSIONIn the present study, we found that the increase incidence of spontaneous arrhythmias, prologation of QT interval and changes in the amplitude of the J wave in the surface ECG during progression of mouse cardiac hypertrophy and failure, and the progressive pattern indicated that a gradual aggravation of the ventricular repolarization delay in this mouse model.

Photodynamic therapy (PDT) has attracted wide attention due to its unique advantages such as minimal invasiveness, high efficiency and high selectivity, and its ability to induce anti-tumor immune response. However, the treatment process is heavily dependent on the oxygen content of the treatment site, and the widespread oxygen deficiency in malignant tumors severely limits its efficacy. In addition, PDT-mediated oxygen depletion exacerbates tumor hypoxia, which further reduces its therapeutic effect. In recent years, many researches have been devoted to overcoming this problem. This paper summarized various strategies based on tumor hypoxic PDT in recent years, discussing the advantages and disadvantages of these strategies, and analyzing the main challenges and future directions of PDT in the treatment of tumors, so as to provide references for the in-depth study of photodynamic therapy of tumors.
