Objective To compare the clinical efficacy between laparoscopic resection and open resection for rectal cancer and explore the safety and feasibility of laparoscopic resection.Methods The clinical data of 68 patients suffering rectal cancer resection were analyzed retrospectively.The patients were divided into laparoscopic group(31 cases)and open group(37 cases)according to the operation method.Results There was no significant difference in the number of lymph nodes dissection and postoperative complication rate between two groups(P > 0.05).The operation time in laparoscopic group was significantly longer than that in open group [(162.03 ±39.78)min vs.(142.70 ±30.29)min].The bleeding in laparoscopic group was less than that in open group [(153.23 ± 58.94)ml vs.(247.46 ± 92.51)ml].The recovery of intestinal function time and hospital stay in laparoscopic group was shorter than that in open group [(51.39 ±7.28)h vs.(77.81 ±11.68)h,(12.65 ±2.24)d vs.(15.29 ±3.11)d].And there were significant differences between two groups(P < 0.05 or < 0.01).Conclusion Laparoscopic resection for rectal cancer can achieve short-term clinical efficacy similar to the traditional open surgery,and advantages in terms of safety and postoperative recovery worthy of further promotion.

Objective To investigate the influence of topiramate(TPM) on quantitative pharmacoelectroencephalography (QPEEG) in normal subjects and epilepsy patients. Methods EEG were recorded in normal and epileptic subjects prior to and at 0.5,1,2,4,6,8,12,24 hours after the administration of single dose of TPM.The EEG power spectral activity including the absolute power,percent of power,total power in both occipital and total power of the whole scalp areas were calculated through 30 s epochs without artifacts after each recording.The statistical difference between baseline assessment and each post-drug time point was analyzed by the Wilcoxon matched-paired rank test. Results The power of sloe wave(peak value 66.76 ?V 2),?1-band (peak value 57.33 ?V 2)and total power (peak value 385.12 ?V 2)was increased after the administration of TPM and the total power of the whole scalp areas was also increased(peak value 2 500.75?V 2).The percent of power of ?-band(peak value 12.4%) and ?1-band(healthy control,peak value 17.5%) or ?-band(patient,peak value 13.94%)was increased,while ?3-band(healthy control,lowest value 10.4%) decreased. Conclusion TPM might change the background activity of EEG that was different from other antiepilepsy drugs.

Objective The quantitative pharmacoelectroencephalography ( QPEEG ) of many antiepileptic drugs (AEDs), such as carbamazepine, valproic acid, phenobarbital and topiramate but not levetiracetam (LEV), have been studied. This study is to investigate the effect of LEV on QPEEG. Methods One dose of LEV at l g was administrated to 12 healthy adults (6 males, average age at 26 years, average height at l.67 m). The EEG samples (of 180 seconds each) were obtained prior to and at regular intervals ( 1, 1.5, 2, 3, 4, 6, 7, 8, 12, 24 hours) after administration of LEV. The EEG activity was processed with the power spectral analysis and separated into different frequency bands. The absolute powers of both occipital and frontal lobes were calculated through 30 seconds epochs without artifacts for each recording. The statistical difference between baseline pre-drug control and each post-drug assessment was evaluated by the Wilcoxon matched-paired rank test. Results The power of α1-band and β-band increased bilaterally over both frontal and occipital lobes after the administration of LEV. There was no change of α2-band over bilateral frontal lobes, but increased in double peaks shape with the low point at the 6 hours after the administration. The power of α1-band showed the significant change after the administration at the 1.5 hours (18.8950, Z= -3.059, P=0.002) in the left front, 3 hours (18.6150, Z= -2.981, P =0.003)in the right front, 1.5, 2, 3 and 4 hours (61.0233, 53.9425, 47.6192 and 51.8250 respectively, Z =-3.059, -3.059, -2.903 and -3.059, all P < 0.01 ) in the left occipital, and 1, 1.5, 2 and 3 hours (53.5358, 56.8092, 50.3500 and 47.1733 respectively, Z = -2.903, -3.059, -3.059 and -2.981,all P < 0.01 ) in the right occipital. The power of α2-band showed the significant change after the administration at the 3 hours (73.5450, Z = - 3.059, P = 0.002) in the left occipital, and 1, 3 hours (80. 6808 and 87. 1750, Z = -2.903 and - 3.059, P = 0.004 and 0.002 respectively ) in the right occipital. The power of β-band showed the significant change after the administration at the 3 hours (3.8000, Z = -3.059, P = 0.002) in the left front, 1.5, 2 and 3 hours (4.0408, 4.3217 and 4. 1050,Z= -2.903, -3.059 and -3.061, all P<0.01) in the right frontal, 3 hours (9.1408, Z= -3.059,P =0.002) in the left occipital, and 1.5, 3 hours (8.9267 and 9.3033, Z = -2.981 and -2.981, both P = 0.003) in the right occipital. Conclusions LEV can change the background activity of QPEEG. The changes are different from those of the other AEDs.

Endocrinology is a new and important medical science.Owing to the great development of modern scientific revolution,it improves quickly.However,the development of endocrinology abides by the laws of epistemology and dialectics.It embodies not only the practicality,penetration,creativity of the scientific cognition,the law of the unity of oppositeness in the growth of the object,but also the high unity of comprehension and analysis of the cognition.

ObjectiveTo investigate the effects of topiramate (TPM) on complexity of electroencephalography (EEG) by means of quantitative pharmacoelectroencephalography (QPEEG) and nonlinear analysis methods.MethodsOne dose of TPM was administrated to epileptics and healthy adults. The EEG samples were obtained prior to and at regular intervals (at 0.5, 1, 2, 4, 6, 8, 12, 24 hours after the administration) within 24 hours following the administration of TPM. The EEG activity was processed with the nonlinear analysis methods. The complexity measure, approximate entropy, Lyapunov exponent and fractional dimension of the whole scalp areas were calculated through 60 seconds epochs without artifacts after each recording. The statistical difference between baseline predrug assessment and each postdrug control was described by analysis of variance.ResultsThe Lyapunov exponent was increased first, then decreased, and then increased finally (the maximum value was 0.44 in both centrals in the healthy people). The approximate entropy and fractional dimension showed the tendency of descent, the complexity measure decreased in healthy adults (the least value was 0.34 on right parietal), but increased in patients (the maximum value was 0.34 in right posterior temporal).ConclusionTPM might change the complexity of EEG.
