BACKGROUND: The attack of temporal epilepsy is associated with the loss and death of hippocampal neurons, in which the specific pattern and mechanism of the loss of hippocampal neurons are still unclear, and it is hard to make sure the inevitable association of the epileptic discharge with activation of cysteine-containing ASPartate-specific protease (caspase 3)and neuronal apoptosis, of hippocampal neurons.OBJECTIVE: To observe the neuronal apoptosis and caspase 3 gene expression of in vitro cultured rat hippocampal neurons of epilepsy models.DESIGN: An open experiment.SETTINGS: Department of Neurosurgery, Changhai Hospital, the Second Military Medical University of Chinese PLA; Department of Neurosurgery,Changzheng Hospital, the University.MATERIALS: The experiments were carried out in the Neurosurgery Laboratory of the Second Military Medical University of Chinese PLA from June 2002 to June 2003. Ten male or female SD rats with 24 hours after birth were used. The Caspase 3 flow detection kit was purchased from American BD Company, and polymerase chain reaction (PCR) primers were synthetized by Shanghai Haojia Company.METHODS: ① The SD rats within 24 hours after birth were killed by cutting down the head to remove the brain, then bilateral hippocampi were taken out, and hippocanpal neuron models of epileptic discharge were established. The discharge of the models was recorded with whole cell patch clamp technique. The neurons cultured for 8 days and treated with Mg-free medium were taken as epileptic discharge model group, and those cultured for 8 days but not treated with Mg-free medium were taken as the blank control group, and the changes of potentials were recorded. ② The fulllength cDNA of caspase 3 was cloned with reverse transcription-polymerase chain reaction (RT-PCR), and then it was labeled. The expression of caspase 3 gene and neuronal apoptosis were detected with in situ hybridization and flow cytometry.MAIN OUTCOME MEASURES: ① Results of cDNA cloning of caspase 3; ② Results of Caspase 3 in situ hybridization; ③ Results of apoptosis.RESULTS: ① The products amplified by RT-PCR showed DNA segment lanes of about 800 bp after treated with 12 g/L agarose gel electrophoresis (Figure 1), which was concordant with the predicted value. The detection of DNA sequence showed that the length of the obtained cloning open-reading frame was 843 bp. ② The hybridization showed that in the blank control group, the positively stained hippocampal neurons were less than 10%, the neurites were well-stacked, and formed extensive synaptic association; In the epileptic discharge model group, the positively stained neurons were obviously increased at 3 hours after the Mg-free treatment, and there were many strongly and positively stained neurons at 12 hours, all these neurons kept the neurites, which became little. ③ The flow cytometry showed that at 6 hours after the Mg-free treatment, the apoptotic cells began to increase obviously, the numbers of apoptotic cells in certain times were not the same.CONCLUSION: Epileptic discharge can trigger the caspase 3 gene expression, by which neuronal apoptosis is induced.

Objective To characterize differences within facial profile esthetic evaluations among three groups of evaluators and the influences of sagittal or vertical skeletal patterns on facial profile esthetics. Methods A total of 114 silhouettes,from the pre?or post?treatment facial profiles of 57 patients,were scored by three groups of evaluators(professionals,patients'parents,and laypersons)to characterize differences within facial es?thetics evaluation among evaluators. The highest?scoring 30 silhouettes and the lowest?scoring 30 silhouettes were selected as the high score group and the low score group,respectively. Sixteen indices of the relative lateral cephalometric films were measured. Data were analyzed by SPSS 21.0. Results Facial profiles following orthodontic treatment scored higher than pre?treatment(P<0.05). There were significant differences between professionals and laypersons in facial profile scoring. Different sagittal skeletal patterns had no effect on esthetic evaluation ,but lower facial height significantly influenced whether a patient received a high or low esthetic score(P<0.05). Conclusion Orthodontic treatment can improve the fa?cial profile significantly,and lower facial height is the most sensitive index for facial profile evaluation in our study. However,all three evaluator groups have different esthetic standards that don't overlap. Notably,the expectations of laymen are higher than those of orthodontists.

BACKGROUND: Ribavirin is easily diluted by lacrimal fluid and has low bioavailability. In situ ophthalmic gel changes from liquid drug to gel phase upon exposure to physiological conditions, resulting in an increase in the precorneal residence time of drugs. OBJECTIVE: To prepare ribavirin in situ ophthalmic gel and valuate its theological feature. DESIGN, TIME AND SETTING: In vitro controlled observation, performed at the Engineering Research Center of Modem Chinese Medicine Discovery and Preparation Technique, Ministry of Education, Tianjin University of Traditional Chinese Medicine between September and October 2006. MATERIALS: Sodium alginate, Carbopol, and ribavirin. METHODS: Sodium alginate (1% and 2%) and Carbopol (0.3%, 0.6%, and 2%) were combined at different proportions to prepare in sire ophthalmic gel, then in which ribavirin was added. MAIN OUTCOME MEASURES: Viscosity determinations of prepared different concentrations of formulations were determined using a cone and plate viscometer. RESULTS: Ribavirin in situ ophthalmic gel prepared with 1% sodium alginate and 0.6% Carbopol had the largest viscosity. The viscosity change was not influenced by the addition of ribavirin. The in situ ophthalmic gel prepared with sodium alginate and Carbopol changed to the gel phase upon exposure to lacrimal fluid. CONCLUSION: 1% sodium alginate and 0.6% Carbopol produced the best rheological feature and could prolonge the precorneal residence time of drug than that of conventional ophthalmic solution.

Objective To investigate the clinical features and risk factors of spondyloarthropathy with anterior uveitis. Methods The clinical and laboratory data of 86 patients with spondyoarthropathy associated with anterior uveitis in our hospital were collected, analyzed and summarized from March 2005 to December 2008, and the patients were followed up as closely as possible. The data of the 86 patients were compared with 93 patients who had spondyloarthropathy without anterior uveitis at the same period. All data were analyzed by using SPSS11.5 software package. Results Compared with non-ophthalmia group, ophthalmia group had significantly longer course[(11 ±8)vs(5±6), P＜0.01], and higher proportion of positive family history(27.9%vs 9.7%, P＜0.01), the proportion of low back pain at night, morning stiffness, spinal deformity, limitation of waist-bending and severe sacroiliac joint lesions were all significantly higher(P＜0.05), HLA-B27 positive rate was significantly higher as well(92.2% vs 81.5%, P＜0.05). The attack of uveitis usually had seasonality and precipitating cause. The patients with anterior uveitis as first symptom had significant higher frequency of ophthalmitis(P＜0.01), the ratio of eye permanent lesions was also significantly higher(P＜0.01). The frequencies of attack were positively correlated with the course of disease(r=0.294, P=0.006), Logistic multiple regression analysis showed that the incidence risk of ophthalmia were related to the course of disease(P=0.013, OR=1.099, 95%CI 1.030～1.183)and severe sacroiliac joint lesions(P=0.012, OR=3.071, 95%CI 1.286 ～7.314). Conclusion The spondyloarthropathy associated with anterior uveitis had its own characteristics, We should pay attention to the risk factors of anterior uveitis,and prevent the recurrence of ophthalmia.

Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P<0?01), 87?5% versus 68?75% (P>0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.
