Objective To explore the risk factors of cognitive function in out-patients with depression in order to direct clinical therapy.Methods The clinical data of 180 cases of epileptic patients with depression from September 2005 to March 2009 were analyzed retrospectively.Results In 180 cases of epileptic patients with depression,82 cases(45.6%) of cognitive function were found,the occurrence with sex,marital status,the site of epileptic foci,the types of epileptic seizures were no significant correlation(P＞0.05),but related with onset age,educational level,disease course,the frequency of epileptic seizures and duration of attack (P＜0.05).Conclusion The risk factors of cognitive function in epileptic patients with depression were onset age,educational level,disease course,seizure frequency and duration of attack,it should avoid the occurrence of these risk factors and improve the quality of life of patients in clinical practice.

ObjectiveTo evaluate the effect on postoperative urinary and sexual function of radical resection with pelvic autonomic nerve preservation for female rectal cancer patients.MethodsPostoperative sex and urination disorders were compared between groups of pelvic autonomic nerve preservation and conventional procedure in 120 female cases of middle-lower rectal carcinoma undergoing radical resection. ResultsThe venery decline、sexual climax slip、vagina wetness degree slip and the coition pain rate were 12.5%、10.5%、8.33%、4.15% in autonomic nerve preservation group and 54.1%、45.9%、41.7%、37.5% in control group, respectively(all P0.05).ConclusionPelvic autonomic nerve preservation is effective to reduce postoperative sex and urination disorders in female rectal cancer cases undergoing radical resection though it does not seem to benift cases receiving posterior pelvic exenteration.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Background Vitreous hemorrhage in long-term produces toxic substances and influent the metabolism of eye tissue.Lens capsule is found more thin and transparent in the eyes with chronic vitreous hemorrhage.To research the effect of vitreous hemorrhage to lens is very important for the choose of the phaco operative timing.Objective The aim of this work was to investigate the ultrastructural change of lens epithelial cells(LECs) in the eyes with experimental vitreous hemorrhage.Methods The autologous blood of 0.1 ml was intravitreally injected in the left eyes of 8 general New Zealand white rabbits,and the equal amount of phosphate buffered saline(pH7.4) was used at the same way in the right eyes.Vitreous and fundus were examined with direct ophthalmoscope on 1,3,5,9,15,20,25,30 days to assess the inflammatory response after intravitreal injection.The specimens of lens anterior capsule were obtained in 30 days after injection and the ultrastructure and apoptosis of LECs were evaluated under the transmission electron microscope. Results No obvious ocular inflammatory response was seen throughout the experimental duration,and there was no vitreous hemorrhage in the right eyes after intravitreal injection.The vitreous hemorrhage agglutinated with clear boundary in the left eyes on 1 day after intravitreal injection,and the hemorrhage turned into dark-red color on the fifth day.On the fifteenth day after injection,the hemorrhage mass became to be grey color and the vitreous liquefaction occurred in the left eyes.The hemorrhage disappeared until 25 days.But in the one month after injection of self-blood,the vitreous showed the deeper red color.The early apoptosis appeared in the LECs of the left eyes in the thirty day,presenting the enlargement and broaden of intercellular space,the decrease of mitochondria number,vacuolar change,expanse of endoplasmic reticulum and disappearance of the nuclear membrane structure. Conclusions Vitreous hemorrhage leads to the ultrastructural pathological changes of lens.

Objective To evaluate MRI in the diagnosis of the bone contusion of the knee joint and its clinical significance.Methods Using special coil for knee joint,coronal,sagittal,axial and oblique sagittal plane scanning with fast spin-echo sequence(T_1WI,T_2WI,PDWI+FS)was performed on knee joint in 205 patients in three days after injury.According the distributing bone marrow edema and injury mechanism,bone contusion were classified five types as pivot shift injury,clip injury,dashboard injury, hyperextension injury and lateral patellar dislocation.Results One hundred and forty-five cases of the 205 patients were found bone marrow edema without fracture on X-ray films.Among them,pivot shift injury was found in 43 cases accompanied with anterior cruciate ligament rupture in 30 cases,tear of the posterior horn of the lateral or medial meniscus in 12 and tears of the medial collateral ligament in 8 cases;clip injury in 53 cases accompanied with anterior cruciate ligament rupture in 10 cases,tear of the posterior horn of the lateral or medial meniscus in 15 and tears of the medial collateral ligament in 38 cases;dashboard injury 40 cases accompanied with posterior cruciate ligament rupture in 16 cases,hyperextension injury 9 cases accompanied with anterior cruciate ligament rupture in 2 cases,posterior cruciate ligament rupture in 5 cases.No lateral patellar dislocation was found.Forty-eight of 145 patients had undergone arthroscopy, 43 cases(89.6%)of them were in accordance with MRI diagnosis.Bone contusion were defined as geographic regions of abnormal signal intensity,that is,low signal intensity in T_1-weighted images and high signal intensity in PD-weighted or T_2-weigeted images with fat saturation.Conclusion MRI can accurately display the location and area of bone contusion of the knee joint as well as its adjunctive structure injury and deduce their injury mechanism.MRI should be used routinely for knee trauma.

ObjectiveTo characterize the neural progenitor cell in the human amnion mesenchyme and epithelial layer with specific mark proteins of neural stem cell.MethodsExpressions of specific mark proteins of neural stem cell including nestin, glial fibrillary acidic protein (GFAP), musashi-1, vimentin and PSA-NCAM in human amnion tissue and cultured amniotic cells were determined by immunohistochemistry and immunofluorescence staining.ResultsExpressions of pluripotent neural stem cell specific makers (nestin, musashi-1, vimentin and PSA-NCAM) were detected in the human amnion mesenchyme and epithelial layer. In addition, cultured amniotic cells were expressed several neural stem cell specific markers including nestin, GFAP and PSA-NCAM. Nestin+ and GFAP+ double positive cells were identified in the human amnion tissue and cultured amniotic cells by immunohistochemistry and immunofluorescence staining.ConclusionSpecific mark proteins of neural stem cell are expressed in human amnion tissue and cultured amniotic cells.
