Objective To explore the clinical and electroencephalography features of children's frontal lobe epilepsy(FLE)and improve the diagnosis and therapy.Methods Medical records were reviewed and neuropsychological evaluations of patients with FLE diagnosed from 2000 to 2006.Children were examined by 24 h EEG and imaging examinations.Their charts for family medical history,seizure,aura,simultaneous phenomenon and anti-epilepic drug therapeutic effects were reviewed.Results Seizures were clonus in 24 cases,tonic in 4 cases,adversive,atonic,vomit in 2 cases,respectively,paresthesia,cephalic,visul,sensory in 1 case,Imaging finding were in 9 of 40.All the 40 cases were bought into 1 to 6 years' follow-up.Long-term control was achieved in 35 of 40.Partial control was achieved in 3 of 40.The left 2 cases had no response to the anti-epileptic drugs.Conclusions The common features of FLE included high seizure frequency,short duration and nocturnal preponderance.There is high positive rate of active EEG in detecting epileptic discharges,and active EEG shoud be necessary.Carbamazepine is recommended to be the first choice to FLE.

Objective To investigate the change of wave-front aberrations after Ortho-K contact lens(CL)by day and overnight wear.Design Retrospective case series.Participant 180 eyes of 92 myopic patients wearing Ortho-K CL.Method Wave-front aberra- tions of 180 eyes of 92 myopic patients wearing Ortho-K CL were analyzed.Patients were divided into by day wear and overnight wear groups.Wave-front aberrations were measured with WFA 1000B subjective aberrometer before and 1 month after Ortho-K CL wear. Wave-front aberrations at initial,after one month of CL fitting and without CL were measured in same condition,and RMS values for overall wave-front aberrations and each order of the Zernike aberrations were analyzed with Matlab software.Main Outcome Measures RMS value of Zernike coefficient of each order.Result Compared with initial aberration in wear by day group,total RMS and each or- der aberrations(except 2nd order)with lens fitting significantly increased(P0.05).Compared with initial aberration in overnight wear group,overall wavefront aberrations and the RMS(except 2nd,3rd and 6th order Zernike aberrations)with lens fitting significantly increased(P0.05).Conclusion The high order aberrations with lens fitting and without lens fit- ting increased in each group.The aberration with lens fitting in wear by day group was higher than that in overnight wear group,while the aberration without lens fitting in overnight wear group was higher than that in wear by day group.(Ophthalmol CHN,2007,16: 351-354)

Objective To investigate effects and safety of dexmedetomidine on the prevention of abnormal mental in patients after liver transplantation.Methods 160 patients after liver transplantation were randomly divided into the two groups using the drawing method:midazolam group(n =80),dexmedetomidine group(n =80),compared the two groups of patients with general,mental abnormality and the occurrence of adverse reactions.Results There were no significant differences in the general situation (gender,age,postoperative ventilator time,ICU stay time,oper-ation time,blood FK506 concentration,APACHEII score 24 hours after operation)of the two groups of patients (P >0.05),the spirit of the abnormal rate of the observation group was lower than that of the control group (P =0.009), incidence of hypotension and hypertension in the observation group was higher than that in the control group (P =0.035,0.029).Conclusion Dexmedetomidine can effectively reduce the postoperative mental disorders in patients in the early stage after liver transplantation.

AIM:To investigate the expression and the significance of VEGF-C/D in rat cornea after alkali burning as well as the role of lymphangiogenesis in the high-risk corneal transplantation rejection.
●METHODS:The model of alkali burn corneal was made. Different times corneas were taken to electron microscope for vascularization, and examined the expression of VEGF-C/D and VEGFR-3 in l, 3, 5, 7, 14, 28d. The other rat cornea after alkali burn were divided into four parts to penetrate keratoplasty, containing only blood vessels in the cornea ( group A ) , angiogenesis and lymphangiogenesis ( group B ) , lymphangiogenesis degenerating period ( group C ) , angiogenesis degenerating period ( group D ) . ln addition, there are also normal groups ( group N ) to compare the Rl values and survival time of corneal graft.
●RESULTS: Electron microscopy showed that, when the first 7d rat cornea appeared neovascularization after alkali burn, but not lymphangiogenesis. The occurrence of new blood vessels and lymphatic in 2wk. There were no obvious lymphangiogenesis in 5wk and the angiogenesis gradually subside in 8 wk. The expression of VEGF-C/D and VEGFR-3 in the corneas of rats were up-regulated in the third days after the injury, and reached its peaks at 5d. The average survival time of group N, A, B, C, D were (14.25±0.62)d, (9.35±1.02)d, (5.06±1.13)d, (8.71±0.83) d, (9. 44±1. 05)d after transplant cornea. Compared to the rest of the group, group B plant average survival time significantly shortened (P<0. 05), while compared with group B, the survival time of A, C, D groups were significantly longer (P<0. 05).
● CONCLUSION: VEGF - C/D and VEGFR - 3 are expressed significantly after corneal alkali burn. New lymphatic vessels can accelerate high - risk corneal transplantation immune rejection.

Objective To review our clinical experience on 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic debridement.Method This retrospective study included 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic dehridement and drainage.Results All the 12 patients recovered well and were finally discharged home.Conclusions Retroperitoneal laparoscopic debridement and drainage for retroperitoneal infection is a mini-invasive procedure.It was found to be safe,produced minimal bleeding and resulted in rapid postoperative recovery.It can be used as the first choice treatment in properly selected patients.

Objective To survey on present situation of medical students' study style and to provide references to improve the development of study style. Methods Totally 512 undergraduate stu-dents of one medical university in Tianjing were asked to fill the questionnaire by themselves. Main con-tents of the questionnaire included study targets,study attitudes,study methods,teaching level,teaching equipments,school training system and management system,etc. Epidata3.02 was used to accomplish data entry and SPSS software was used to do statistical analysis. The data were described by percentage. Results More than 50.0% students took attending post-graduate examination,passing college English test band 4 and band 6 and getting diploma as main study purposes. 81.96%(404/499)medical stu-dents spent their spare time on study by themselves. 98.40%(491/499)students took notes in class,while only 8.62%(43/499)students often discussed questions with their teachers after class. 70.54%students said that they ever attended academic lectures organized by college and achieved benefits from them. 40.88%(204/499)students were highly eager to win scholarship. More than half of the students took gloomy atti-tude towards getting a job and this phenomenon should cause educators' attention. 78.56%(392/499 ) students held the opinion that medical professional teachers have higher teaching level and 26.65%(133/499 ) students thought that college's teaching equipments should be improved . Conclusions Following aspects should be emphasized in order to further strengthen and improve medical students' study style:making further efforts to arouse students' study initiative,playing the leading role of teach-ers and promoting study style by promoting teaching style,improving rules and regulations of study style development and strengthening college's hardware construction.
