Objective To evaluate and compare the advantages and disadvantages and the clinical application between transvaginal abdominal hysterectomy(TAH)and laparoscopically assisted vaginal hysterectomy(LAVH)on the benign lesions of non-prolapsed uterus.Methods 400 patients with benign lesions of non-prolapsed uterus were divided into two groups,TAH group(202 cases)and LAVH group(198 cases).The effects of clinical treatment of the two groups were compared.Results There were significant differentces between the two groups in operation time,the blood loss,passage of gas by anus,return to normal activities,and overall cost of treatment.However,after 1to 3 months follow-up,all patients were good in terms of outcome.Conclusion Different surgical patterns of hysterectomy had their distinctive advantages.The key point of a successful operation Was to avoid complications of the operation.

Objective To study the effects of repetitive transcranial magnetic stimulation (rTMS) on rats'locomotor function after hemisectional spinal cord injury (SCI). Methods A model of hemisectional SCI was established at the T10 segment in 12 rats,which were then randomly divided into an SCI-rTMS group and an SCI-control group.Another 6 rats served as normal controls.The SCI-rTMS group received threshold rTMS daily for 4 weeks,while the SCI-control group was given sham rTMS.The normal control group was left without any treatment.BassoBeatti-Bresnahan (BBB) locomotor scores were recorded weekly.Motor evoked potential (MEP) was detected at the 28th day after the operation.Neurofilament-200 (NF-200) was detected with immunofluorescent staining of the spinal cord lesions. Results The BBB scores in the SCI-rTMS group improved more than those in the SCI-control group.MEP of the fight hindlimb was detected in the rTMS group,but not in the control group.Expression of NF-200 marker increased significantly more than in the rTMS group. Conclusions rTMS can improve locomotor function of rats after spinal cord hemisectioning,which may result from increased expression of NF-200 and the regeneration of axons.

Objective To investigate the changes of non-linear dynamics properties of EEG under different mental tasks,and the application of non-linear dynamic analysis for cognitive function research. Methods EEG was recorded in 30 healthy university students under four states: eyes closed,eyes open,mental arithmetic with eyes closed and graphic reasoning test with eyes open.Correlation dimension (D 2) and point-wise correlation dimension (PD 2) were calculated for all subjects.We also performed a surrogate data test in 5 randomized selected subjects. Results In all states tested,the results argued for the presence of non-linearity and fractal D 2 and PD 2.D 2 and PD 2 increased significantly during mental tasks as compared to the rest states (D 2 of above four states was 3.93,4.47,4.33 and 4.98 respectively).The results showed that values of D 2 and PD 2 fluctuated with time,which suggests an intermittent activation of the brain areas participated in the task.With non-linear dynamic analysis,there might be a working circuit from bilateral temporal lobes to the left frontal lobe and parental lobe under mental arithmetic task.Conclusions Through dynamic analysis based on D 2 and PD 2 topographic maps,we can see clearly the distribution of D 2 and PD 2 in the brain,the sequence and the degree of activation of the regions involved in the cognitive task under mental tasks.Dynamic and short-time non-linear analysis methods are more appropriate for the study of mental functions.Non-linear dynamic analysis might help us understand the working mechanism of brain during mental activities.

Pseudotemporal lobe epilepsy refers to an electroencephalogram (EEG) ictal pattern that is localized to the temporal region and the clinical ictal symptoms like the temporal seizure, especially mesial temporal seizure. But the epileptogenic zone is on the extratemporal regions. It is not easy to diagnose pseudotemporal lobe epilepsy. There are difficulties to detect by scalp EEG, and stereoelectroencephalography is usually required for epileptogenetic zone localization. Pseudotemporal lobe epilepsy almost is refractory for antiepileptic drugs. But the situation is illustrated by the failure of temporal lobe surgery resection alone. Therefore, the good result is often obtained after an epileptogenic zone and symptomatic zone resection.

METHODS:56cases of chronic hepatitis C were divided into trial group(30cases)and control group(26cases).Trial group received IF ?-2b +compound glycyrrhizin and control group received IF ?-2b alone.The therapeutic course was24weeks in both groups.RESULTS:There was significant difference in recoversion rate of ALT between two groups either at the end of ther?apeutic course or24weeks after treatment(P

Objective To investigate the clinical efficacy of combined use of acupuncture and medicine in treating spasmodic torticollis.Method Thirty patients were randomly allocated to a treatment group of 15 cases and a control group of 15 cases. The treatment group received combined use of acupuncture and medicine, and the control group, acupuncture alone.Result Clinical observation lasted one year. There was a statistically significant pre-/post-treatment difference in the Tsui score in the two groups at 6 and 12 months after treatment (P<0.01). There was a statistically significant difference in the Tsui score between at 6 and 12 months after treatment in the two groups (P<0.01); the Tsui score decreased gradually after treatment. There was a statistically significant post-treatment difference in the Tsui score between the two groups at 12 months after treatment (P<0.05); the Tsui score decreased more in the treatment group.Conclusion The cure and marked efficacy rate of combined use of acupuncture and medicine for spasmodic torticollis is higher than that of acupuncture alone. A longer course is needed for acupuncture treatment of spasmodic torticollis and the patient should persevere with the treatment.

Objective To study the percentage and cause of new seizure types in epilepsy patients and attempt to evaluate the value of new seizure types.Methods All 1074 eapilepsy patients were envolled in the retrospectively study.The types of seizure were diagnosed according to International League Against Epilepsy seizure classification and neuroimaging results of the patients.The Wilcoxon signed rank sum test was used to assess the difference of age at first seizure and mean duration of epilepsy patients with and without new seizure types.The chi-square test was used to compare the abnormal proportion of EEG and neuroimaging results of epilepsy patients.Results Two hundred and thirty-one(21.5%)of 1074 epilepsy patients experienced new seizure type.Five hundred and eighty-four patients had partial seizure with 132 (22.6%)experiencing new types of seizure while 490 patients had generalized seizure with 99(20.2%)experiencing new types of seizure.Five hundred and seventy-six(53.6%)had abnormal EEG and 237 (22.1%)had abnormal neuroimaging in 1074 epilepsy patients.A hundred and twenty-three(52.3%)of 231 patients with new seizure types had abnormal EEG,and 75(32.5%)of them had abnormal neuroimaging. The possible causes for the new types of seizure could be found in 41 patients.There were no significant difference in the age of the first onset between the patients with and without the new types of seizure while there was significant difference in the average course of disease between them(χ~2=18.511-23.836.P＜0.05).There were significant differences in the rates of abnormal results of examination of nervous system and imaging outcomes.Conclusions There may be different causes of new seizure types.The study of new seizure types is helpful in diagnosis,treatment and prevention of epilepsy.

AIM: To evaluate the effect of luteolin on ulcerative colitis in experimental animals. METHODS: The mouse model of acute colitis was induced by instillation of dinitrochlorobenzene (DNCB) /alcohol. Luteolin (1, 10 and 50 mg?kg~(-1)) were orally administrated to mice for 3 days. Diarrheas, colon weight index, macroscopic damage in the colon were observed and the activity of MPO and the content of PGE_2 in colon were also examined. RESULTS: The diarrhea and the colon weight in- dex were reduced and the macroscopic damage in the inflammatory colon was effectively attenuated by luteolin. The elevated level of MPO and PGE2 were also significantly decreased. CONCLUSION: Luteolin can effectively inhibit the inflammatory infiltration, bleeding and proliferation in experimental ulcerative colitis.
